PRELIMINARY—SUBJECT TO COMPLETION—DATED MARCH 9, 2020

To the shareholders of First Horizon National Corporation and IBERIABANK Corporation

MERGER PROPOSED—YOUR VOTE IS VERY IMPORTANT

On November 3, 2019, First Horizon National Corporation (“First Horizon”) and IBERIABANK Corporation (“IBKC”) entered into an Agreement and Plan of Merger (as amended from time to time, the “merger agreement”), pursuant to which First Horizon and IBKC have agreed to combine their respective businesses in a merger of equals. Under the merger agreement, IBKC will merge with and into First Horizon (the “merger”), with First Horizon as the surviving entity (the “combined company” or “First Horizon,” as the case may be). Following the completion of the merger, IBERIABANK, a subsidiary of IBKC, will merge with and into First Horizon Bank, a subsidiary of First Horizon, with First Horizon Bank as the surviving bank (the “bank merger”). The merger will bring together two companies with complementary franchises to create one of the largest financial services companies headquartered in the South and one of the top 25 banks in the United States based on deposits.

In the merger, holders of IBKC common stock will receive 4.584 shares (the “exchange ratio” and such shares, the “merger consideration”) of First Horizon common stock for each share of IBKC common stock they own. Holders of First Horizon common stock will continue to own their existing shares of First Horizon common stock. Based on the closing price of First Horizon’s common stock on the New York Stock Exchange (“NYSE”) on November 1, 2019, the last trading day before public announcement of the merger, the exchange ratio represented approximately $74.76 in value for each share of IBKC common stock, representing merger consideration of approximately $3.9 billion on an aggregate basis. Based on First Horizon’s closing price on [ ], 2020 of $[ ], the exchange ratio represented approximately $[ ] in value for each share of IBKC common stock, representing merger consideration of approximately $[ ] on an aggregate basis. The value of the First Horizon common stock at the time of completion of the merger could be greater than, less than or the same as the value of First Horizon common stock on the date of the accompanying joint proxy statement/prospectus. We urge you to obtain current market quotations of First Horizon common stock (trading symbol “FHN”) and IBKC common stock (trading symbol “IBKC”).

In addition, each share of IBKC preferred stock issued and outstanding immediately prior to the effective time will be converted into the right to receive one (1) share of an applicable newly issued series of rollover First Horizon preferred stock with terms that are the same as the terms of the applicable series of outstanding IBKC preferred stock. Likewise, following the completion of the merger, each outstanding IBKC depositary share representing a 1/400th interest in a share of the applicable series of IBKC preferred stock will become a First Horizon depositary share and will represent a 1/400th interest in a share of the applicable series of rollover First Horizon preferred stock. The IBKC depositary shares representing a 1/400th interest in a share of IBKC series B preferred stock, IBKC series C preferred stock and IBKC series D preferred stock are currently listed on the The NASDAQ Stock Market LLC under the symbol “IBKCP,” “IBKCO,” and “IBKCN,” respectively. The First Horizon depositary shares representing a 1/400th interest in a share of rollover First Horizon series B preferred stock, First Horizon series C preferred stock and First Horizon series D preferred stock are expected to be listed on the NYSE upon completion of the merger.

We expect the merger will qualify as a reorganization for federal income tax purposes. Accordingly, holders of IBKC common stock or IBKC preferred stock generally will not recognize any gain or loss for federal income tax purposes on the exchange of shares of IBKC common stock or IBKC preferred stock, as applicable, for First Horizon common stock or rollover First Horizon preferred stock, as applicable, in the merger, except with respect to any cash received by such holders.

Based on the current number of shares of IBKC common stock outstanding or reserved for issuance, First Horizon expects to issue approximately 244 million shares of First Horizon common stock to holders of IBKC common stock in the aggregate in the merger. Following the completion of the merger, we estimate that former holders of IBKC common stock will own approximately 44% and former holders of First Horizon common stock will own approximately 56% of the common stock of the combined company. At the effective time, each outstanding IBKC depositary share (other than IBKC depositary shares in respect of dissenting shares of IBKC preferred stock) will become a rollover First Horizon depositary share and

will represent a 1/400th interest in a share of the applicable series of rollover First Horizon preferred stock, which will have terms that are the same as the terms of the applicable series of outstanding IBKC preferred stock. At the effective time, there will be 3,200,000 depositary shares of newly created First Horizon series B preferred stock (each representing an 1/400 interest in one (1) of the 8,000 newly created underlying shares of First Horizon series B preferred stock), 2,300,000 depositary shares of newly created First Horizon series C preferred stock (each representing an 1/400 interest in one (1) of the 5,750 newly created underlying shares of First Horizon series C preferred stock) and 4,000,000 depositary shares of newly created First Horizon series D preferred stock (each representing an 1/400 interest in one (1) of the 10,000 newly created underlying shares of First Horizon series D preferred stock).

First Horizon and IBKC will each hold a special meeting of our respective shareholders in connection with the merger. At our respective special meetings, in addition to other business, First Horizon will ask holders of its common stock and IBKC will ask holders of its common stock to approve the merger. Information about these meetings and the merger is contained in this document. In particular, see “Risk Factors” beginning on page 41. We urge you to read this document carefully and in its entirety.

Holders of IBKC preferred stock and holders of depositary shares representing interests in the shares of the applicable series of IBKC preferred stock are not entitled to and are not requested to vote at the IBKC special meeting. Holders of First Horizon preferred stock and holders of depositary shares representing interests in the shares of First Horizon preferred stock are not entitled to and are not requested to vote at the First Horizon special meeting.

The special meeting of holders of IBKC common stock will be held on [ ], 2020 at [ ], at [ ], local time. The special meeting of holders of First Horizon common stock will be held on [ ], 2020 at [ ], at [ ], local time.

Whether or not you plan to attend your special meeting, please vote as soon as possible to make sure that your shares are represented at the meeting. If you do not vote your shares of common stock, it will have the same effect as voting “AGAINST” the merger.

Each of our boards of directors unanimously recommends that holders of common stock vote “FOR” each of the proposals to be considered at the respective meetings. We strongly support this combination of our companies and join our boards in their recommendations.

This joint proxy statement/prospectus provides you with detailed information about the merger agreement and the merger. It also contains or references information about First Horizon and IBKC and certain related matters. You are encouraged to read this joint proxy statement/prospectus carefully. In particular, you should read the “Risk Factors” section beginning on page 41 for a discussion of the risks you should consider in evaluating the proposed merger and how it will affect you.

NOTICE OF SPECIAL MEETING OF SHAREHOLDERS

To IBKC Shareholders:

On November 3, 2019, First Horizon National Corporation (“First Horizon”) and IBERIABANK Corporation (“IBKC”) entered into an Agreement and Plan of Merger (as amended from time to time, the “merger agreement”), a copy of which is attached as Annex A to the accompanying joint proxy statement/prospectus.

NOTICE IS HEREBY GIVEN that a special meeting of holders of IBKC common stock (the “IBKC special meeting”) will be held on [ ], 2020 at [ ], local time at [ ]. We are pleased to notify you of and invite you to the IBKC special meeting.

At the IBKC special meeting, holders of IBKC common stock will be asked to vote on the following matters:

| • |  | Proposal to approve the merger agreement (the “IBKC merger proposal”).
| • |  | Proposal to approve, on an advisory (non-binding) basis, the merger-related compensation payments that will or may be paid by IBKC to its named executive officers in connection with the merger (the “IBKC compensation proposal”).
| • |  | Proposal to adjourn the IBKC special meeting, if necessary or appropriate, to solicit additional proxies if, immediately prior to such adjournment, there are not sufficient votes to approve the IBKC merger proposal or to ensure that any supplement or amendment to the accompanying joint proxy statement/prospectus is timely provided to holders of IBKC common stock (the “IBKC adjournment proposal”).

The board of directors of IBKC has fixed the close of business on February 24, 2020 as the record date for the IBKC special meeting. Only holders of record of IBKC common stock and IBKC preferred stock as of the close of business on the record date for the IBKC special meeting are entitled to notice of the IBKC special meeting or any adjournment or postponement thereof. Only holders of record of IBKC common stock will be entitled to vote at the IBKC special meeting or any adjournment or postponement thereof.

IBKC has determined that holders of IBKC common stock are not entitled to appraisal rights with respect to the proposed merger under Section 12:1-1302 of the Louisiana Business Corporation Act (“LBCA”).

Holders of IBKC preferred stock are entitled to exercise appraisal rights in connection with the merger, provided the proper procedures of Part 13 of the LBCA are followed. A copy of Part 13 of the LBCA is attached as Annex E to the accompanying joint proxy statement/prospectus.

Holders of IBKC preferred stock have appraisal rights under the LBCA in connection with the proposed merger. Because appraisal rights are available to preferred shareholders, the following notice of such rights is required under Part 13 of the LBCA:

Appraisal rights allow a shareholder to avoid the effects of the proposed corporate action described in this notice by selling the shareholder’s shares to the corporation at their fair value, paid in cash. To retain the right to assert appraisal rights, a shareholder is required by law: (1) to deliver to the corporation, before the vote is taken on the action described in this notice, a written notice of the shareholder’s intent to demand appraisal if the corporate action proposed in this notice takes effect, and (2) not to vote, or cause or permit to be voted, in favor of the proposed corporate action any shares of the class or series for which the shareholder intends to assert appraisal rights. If a shareholder complies with those requirements, and the action proposed in this notice takes effect, the law requires the corporation to send

to the shareholder an appraisal form that the shareholder must complete and return, and a copy of Part 13 of the Business Corporation Act, governing appraisal rights.

The IBKC board of directors unanimously recommends that holders of IBKC common stock vote “FOR” the IBKC merger proposal, “FOR” the IBKC compensation proposal and “FOR” the IBKC adjournment proposal.

Your vote is important. We cannot complete the transactions contemplated by the merger agreement unless holders of IBKC common stock approve the merger agreement. The affirmative vote of a majority of all the votes entitled to be cast on the merger agreement by the holders of IBKC common stock is required to approve the IBKC merger proposal.

Whether or not you plan to attend the IBKC special meeting, we urge you to please promptly complete, sign, date and return the accompanying proxy card in the enclosed postage-paid envelope or authorize the individuals named on the accompanying proxy card to vote your shares by calling the toll-free telephone number or by using the Internet as described in the instructions included with the accompanying proxy card. If your shares are held in the name of a bank, broker or other nominee, please follow the instructions on the voting instruction card furnished by such bank, broker or other nominee.

| Q: |  | Why am I receiving this joint proxy statement/prospectus?
| A: |  | You are receiving this joint proxy statement/prospectus because First Horizon and IBKC have agreed to combine their companies in a merger of equals structured through a merger of IBKC with and into First Horizon (the “merger”), with First Horizon as the surviving entity (the “combined company” or “First Horizon,” as the case may be). A copy of the Agreement and Plan of Merger, dated as of November 3, 2019, by and between First Horizon and IBKC (the “merger agreement”) is attached as Annex A to this joint proxy statement/prospectus and is incorporated by reference herein. Following the completion of the merger, IBERIABANK, a subsidiary of IBKC, will merge with and into First Horizon Bank (the “bank merger”), a

1

|  |  | subsidiary of First Horizon, with First Horizon Bank as the surviving bank (the “combined bank”). In this joint proxy statement/prospectus, we refer to the closing of the transactions contemplated by the merger agreement as the “closing” and the date on which the closing occurs as the “closing date.”
|  |  | In order to complete the merger, among other things:

| • |  | holders of First Horizon common stock must approve the merger agreement (the “First Horizon merger proposal”);
| • |  | holders of First Horizon common stock must approve the proposed amendment of the restated charter of First Horizon (the “First Horizon charter”) to effect an increase in the number of authorized shares of First Horizon common stock from 400,000,000 to 700,000,000 (the “First Horizon charter amendment proposal”); and
| • |  | holders of IBKC common stock must approve the merger agreement (the “IBKC merger proposal”).

First Horizon is holding a special meeting of holders of First Horizon common stock (the “First Horizon special meeting”) to obtain approval of the First Horizon merger proposal and the approval of the First Horizon charter amendment proposal. Holders of First Horizon preferred stock are also entitled to notice of the special meeting, but holders of First Horizon preferred stock and holders of depositary shares representing interests in the shares of First Horizon preferred stock are not entitled to and are not requested to vote at the First Horizon special meeting.

Holders of First Horizon common stock will also be asked to approve the proposal to adjourn the First Horizon special meeting to solicit additional proxies (i) if there are not sufficient votes at the time of the First Horizon special meeting to approve the First Horizon merger proposal and/or the First Horizon charter amendment proposal or (ii) if adjournment is necessary or appropriate to ensure that any supplement or amendment to this joint proxy statement/prospectus is timely provided to holders of First Horizon common stock (the “First Horizon adjournment proposal”). Pursuant to First Horizon’s bylaws, whether or not a quorum is obtained at the First Horizon special meeting, the chairman of the First Horizon special meeting may adjourn the meeting without notice, except as provided by law and other than by announcement at the First Horizon special meeting, and may do so without a vote of holders of First Horizon common stock. Holders of First Horizon common stock will also be asked to approve, on an advisory (non-binding) basis, the merger-related compensation payments that will or may be paid by First Horizon to its named executive officers in connection with the merger (the “First Horizon compensation proposal”).

IBKC is holding a special meeting of holders of IBKC common stock (the “IBKC special meeting”) to obtain approval of the IBKC merger proposal. Holders of IBKC preferred stock will receive appraisal rights and are also entitled to notice of the special meeting. Holders of IBKC preferred stock and holders of IBKC depositary shares are not entitled to and are not requested to vote at the IBKC special meeting.

Holders of IBKC common stock will also be asked to approve, on an advisory (non-binding) basis, the merger-related compensation payments that will or may be paid by IBKC to its named executive officers in connection with the merger (the “IBKC compensation proposal”) and to approve the proposal to adjourn the IBKC special meeting to solicit additional proxies (i) if there are not sufficient votes at the time of the IBKC special meeting, to approve the IBKC merger proposal or (ii) if adjournment is necessary or appropriate, to ensure that any supplement or amendment to this joint proxy statement/prospectus is timely provided to holders of IBKC common stock and holders of IBKC preferred stock (the “IBKC adjournment proposal”). Under IBKC’s bylaws, the IBKC special meeting may be adjourned without new notice being given unless a new record date is set for the adjourned meeting. Pursuant to IBKC’s bylaws and except as may be otherwise required by law or IBKC’s articles of incorporation, the IBKC board of directors may, by resolution upon public notice given prior to the scheduled date of the IBKC special meeting, postpone the IBKC special meeting.

This document is also a prospectus that is being delivered to holders of IBKC common stock and holders of IBKC preferred stock because, in connection with the merger, First Horizon is offering shares of First Horizon common stock to holders of IBKC common stock and is also issuing shares of rollover First Horizon preferred stock to holders of the applicable series of IBKC preferred stock. Each share of IBKC preferred stock will be automatically converted into the right to receive one (1) share of the applicable series of rollover First Horizon preferred stock in the merger. Under the Louisiana Business Corporation Act (the “LBCA”), holders of IBKC preferred stock will receive appraisal rights in connection with the merger. Following the completion of the merger, each outstanding IBKC depositary share will be automatically converted into a rollover First Horizon depositary share.

This joint proxy statement/prospectus contains important information about the merger and the other proposals being voted on at the First Horizon and IBKC special meetings. You should read it carefully and in its entirety. The enclosed materials allow you to have your shares of common stock voted by proxy without attending your meeting.

After completion of the merger, IBKC will no longer be a public company, and IBKC common stock and IBKC depositary shares will be delisted from the The NASDAQ Stock Market LLC (“NASDAQ”), will be deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and will cease to be publicly traded. Holders of First Horizon common stock will continue to own their existing shares of First Horizon common stock. See the information provided in the section entitled “The Merger Agreement—Structure of the Merger” beginning on page 141 and the merger agreement for more information about the merger.

Shares held in “street name” may be voted in person by you only if you obtain a signed legal proxy from your bank, broker or other nominee giving you the right to vote the shares.

| Q: |  | What matters will be considered at each of the special meetings?

| • |  | First Horizon Proposal 4: The First Horizon adjournment proposal. Approval of the adjournment of the First Horizon special meeting to solicit additional proxies if a quorum is not present and (i) if there are not sufficient votes at the time of the First Horizon special meeting to approve the First Horizon merger proposal and/or the First Horizon charter amendment proposal or (ii) if necessary or appropriate, to ensure that any supplement or amendment to this joint proxy statement/prospectus is timely provided to holders of First Horizon common stock.

|  |  | At the IBKC special meeting, holders of IBKC common stock will be asked to consider and vote on the following proposals:

| • |  | IBKC Proposal 1: The IBKC merger proposal. Approval of the merger agreement;
| • |  | IBKC Proposal 2: The IBKC compensation proposal. Approval of, on an advisory (non-binding) basis, the merger-related compensation payments that will or may be paid by IBKC to its named executive officers in connection with the merger; and

In order to complete the merger, among other things, holders of First Horizon common stock must approve the First Horizon merger proposal and the First Horizon charter amendment, and holders of IBKC common stock must approve the IBKC merger proposal. None of the approval of the First Horizon adjournment proposal, the First Horizon compensation proposal, the IBKC compensation proposal or the IBKC adjournment proposal are conditions to the obligations of First Horizon or IBKC to complete the merger.

| Q: |  | What will holders of IBKC common stock receive in the merger?
| A: |  | In the merger, holders of IBKC common stock will receive 4.584 shares of First Horizon common stock for each share of IBKC common stock held immediately prior to the completion of the merger. First Horizon will not issue any fractional shares of First Horizon common stock in the merger. Holders of IBKC common stock who would otherwise be entitled to a fractional share of First Horizon common stock in the merger will instead receive an amount in cash (rounded to the nearest cent) determined by multiplying the average closing-sale price per share of First Horizon common stock for the consecutive period of five (5) trading days immediately preceding (but not including) the day on which the merger is completed (the “First Horizon closing share value”) by the fraction of a share (rounded to the nearest thousandth when expressed in decimal) of First Horizon common stock that such shareholder would otherwise be entitled to receive.

| Q: |  | What will holders of IBKC preferred stock receive in the merger?
| A: |  | In the merger, each share of IBKC series B preferred stock, IBKC series C preferred stock and IBKC series D preferred stock, in each case issued and outstanding immediately prior to the effective time and excluding dissenting shares, will be converted into the right to receive one (1) share of First Horizon series B preferred stock, First Horizon series C preferred stock and First Horizon series D preferred stock, respectively.

| Q: |  | What will holders of IBKC depositary shares receive in the merger?
| A: |  | In the merger, each outstanding IBKC depositary share (other than IBKC depositary shares in respect of dissenting shares of IBKC preferred stock) will become a rollover First Horizon depositary share and will represent a 1/400th interest in a share of the applicable series of rollover First Horizon preferred stock, which will have terms that are the same as the terms of the applicable series of outstanding IBKC preferred stock. Upon completion of the merger, First Horizon will assume the obligations of IBKC under the applicable deposit agreements. For more information, see “Description of Rollover First Horizon Preferred Stock” beginning on page 172.

| Q: |  | What will holders of First Horizon common stock receive in the merger?
| A: |  | In the merger, holders of First Horizon common stock will not receive any consideration, and their shares of First Horizon common stock will remain outstanding and will constitute shares of the combined company. Following the merger, shares of First Horizon common stock will continue to be traded on the New York Stock Exchange (“NYSE”).

| Q: |  | Will the value of the merger consideration change between the date of this joint proxy statement/prospectus and the time the merger is completed?
| A: |  | Yes. Although the number of shares of First Horizon common stock that holders of IBKC common stock will receive is fixed, the value of the merger consideration will fluctuate between the date of this joint proxy statement/prospectus and the completion of the merger based upon the market value for First Horizon common stock. Any fluctuation in the market price of First Horizon common stock will change the value of the shares of First Horizon common stock that holders of IBKC common stock will receive. Neither First Horizon nor IBKC is permitted to terminate the merger agreement as a result of any increase or decrease in the market price of First Horizon common stock or IBKC common stock.

| Q: |  | How will the merger affect IBKC equity awards?
| A: |  | With respect to IBKC equity awards granted prior to the execution of the merger agreement, unless otherwise mutually agreed by the parties and a holder of any such IBKC equity award, at the effective time:

| • |  | each outstanding and unexercised option to purchase IBKC common stock under IBKC’s equity compensation plans (each an “IBKC stock option”) shall, automatically and without any required action on the part of the holder thereof, vest and be converted into an option to purchase First Horizon common stock based on the exchange ratio and be subject to the same terms and conditions, after giving effect to any “change in control” provisions under the applicable IBKC equity incentive plan or award agreement, that applied to the corresponding IBKC stock option immediately prior to the effective time;
| • |  | each outstanding award in respect of a share of IBKC common stock subject to vesting, repurchase or other lapse restriction (each an “IBKC restricted stock award”) shall, automatically and without any required action on the part of the holder thereof, vest and be converted into the right to receive the merger consideration;
| • |  | each outstanding performance stock unit award in respect of shares of IBKC common stock (each, an “IBKC PSU”) shall, automatically and without any required action on the part of the holder thereof, vest and be converted into the right to receive the merger consideration, with the number of IBKC PSUs entitled to receive the merger consideration determined immediately prior to the effective time based on the greater of (i) the target performance level or (ii) the actual performance level through September 30, 2019, as reasonably determined by the compensation committee of the IBKC board of directors; and
| • |  | each outstanding phantom stock award in respect of shares of IBKC common stock (each, an “IBKC phantom stock award”) shall, automatically and without any required action on the

5

|  |  | part of the holder thereof, vest and entitle the holder of such IBKC phantom stock award to an amount in cash equal to the product of (i) the closing price of one (1) share of First Horizon common stock on the closing date and (ii) the number of shares of First Horizon common stock underlying such IBKC phantom stock award, adjusted based on the exchange ratio.

To the extent the terms of any IBKC equity award granted on or after the date of the merger agreement expressly provide for treatment in connection with the occurrence of the effective time that is different from the treatment described above, or the parties and a holder of any IBKC equity award mutually agree to treatment that is different from the treatment described above, then in each case, the terms of such IBKC equity award or mutual agreement, as applicable, shall control; provided that, at the effective time, each such IBKC equity award will automatically and without any required action on the part of the holder thereof, cease to represent an equity award denominated in shares of IBKC common stock and will be converted into an equity award denominated in shares of First Horizon common stock (based on the exchange ratio).

| Q: |  | What if I own IBKC depositary shares and wish to exercise appraisal rights?
|  |  | If you hold IBKC depositary shares and you wish that appraisal rights be exercised in respect of the merger, IBKC requests that you complete the form of instruction to be provided to you (in accordance with the instructions set out in the form) and return it to your bank, broker or other nominee, as applicable, to direct the depository to exercise appraisal rights on your behalf following the depository’s usual procedures and in accordance with requirements of Louisiana law.
|  |  | In the merger, each share of IBKC preferred stock issued and outstanding immediately prior to the effective time (other than dissenting shares) will be converted into the right to receive one (1) share of an applicable newly issued series of First Horizon preferred stock having the same terms as the terms of such share of IBKC preferred stock. For more information, see “Description of Rollover First Horizon Preferred Stock” beginning on page 172.

| Q: |  | How does the First Horizon board of directors recommend that I vote at the First Horizon special meeting?
| A: |  | The First Horizon board of directors unanimously recommends that you vote “FOR” the First Horizon merger proposal, “FOR” the First Horizon charter amendment proposal, “FOR” the First Horizon compensation proposal and “FOR” the First Horizon adjournment proposal.
|  |  | In considering the recommendations of the First Horizon board of directors, holders of First Horizon common stock should be aware that First Horizon directors and executive officers may have interests in the merger that are different from, or in addition to, the interests of holders of First Horizon common stock generally. For a more complete description of these interests, see the information provided in the section entitled “The Merger—Interests of Certain First Horizon Directors and Executive Officers in the Merger” beginning on page 113.

| Q: |  | How does the IBKC board of directors recommend that I vote at the IBKC special meeting?

| Q: |  | What vote is required for the approval of each proposal at the First Horizon special meeting?
| A: |  | First Horizon Proposal 1: First Horizon merger proposal. Approval of the First Horizon merger proposal requires the affirmative vote of a majority of all the votes entitled to be cast on the First Horizon merger proposal by the holders of First Horizon common stock. Shares of First Horizon common stock not present, and shares present and not voted, whether by broker non-vote, abstention or otherwise, will have the same effect as votes cast “AGAINST” the proposal to approve the merger agreement.

7

|  |  | First Horizon Proposal 2: First Horizon charter amendment proposal. Approval of the First Horizon charter amendment proposal to effect an increase in the number of authorized shares of First Horizon common stock from 400,000,000 to 700,000,000 requires the affirmative vote of a majority of the votes cast on the First Horizon charter amendment proposal by the holders of First Horizon common stock. Accordingly, an abstention or a broker non-vote or other failure to vote will have no effect on the outcome of the First Horizon charter amendment proposal.
|  |  | First Horizon Proposal 3: First Horizon compensation proposal. Approval of the First Horizon compensation proposal requires the affirmative vote of a majority of the votes cast by the holders of First Horizon common stock. Accordingly, an abstention or a broker non-vote or other failure to vote will have no effect on the outcome of the First Horizon compensation proposal.
|  |  | First Horizon Proposal 4: First Horizon adjournment proposal. Approval of the First Horizon adjournment proposal requires the affirmative vote of a majority of the votes cast by the holders of First Horizon common stock at the First Horizon special meeting.

| A: |  | IBKC Proposal 1: IBKC merger proposal. Approval of the IBKC merger proposal requires the affirmative vote of a majority of all the votes entitled to be cast on the IBKC merger proposal by the holders of IBKC common stock. Shares of IBKC common stock not present, and shares present and not voted, whether by broker non-vote, abstention or otherwise, will have the same effect as votes cast “AGAINST” the proposal to approve the merger agreement.

Accordingly, an abstention or a broker non-vote or other failure to vote will have no effect on the outcome of the IBKC compensation proposal.

| Q: |  | Why am I being asked to consider and vote on a proposal to approve, by non-binding, advisory vote, merger-related compensation arrangements for the First Horizon and IBKC named executive officers (i.e., the First Horizon compensation proposal and the IBKC compensation proposal)?
| A: |  | Under Securities and Exchange Commission (“SEC”) rules, First Horizon and IBKC are required to seek a non-binding, advisory vote with respect to the compensation that may be paid or become payable to First Horizon’s or IBKC’s named executive officers, respectively, that is based on or otherwise relates to the merger.

| Q: |  | What happens if holders of First Horizon or IBKC common stock do not approve, by non-binding, advisory vote, merger-related compensation arrangements for First Horizon’s or IBKC’s named executive officers (i.e., the First Horizon compensation proposal and the IBKC compensation proposal?)
| A: |  | The votes on the proposals to approve the merger-related compensation arrangements for each of First Horizon’s and IBKC’s named executive officers are separate and apart from the votes to approve the other proposals being presented at the First Horizon and IBKC special meetings. Because the votes on the proposals to approve the merger-related executive compensation are advisory in nature only, they will not be binding upon First Horizon, IBKC, or the combined company in the merger. Accordingly, the merger-related compensation will be paid to First

8

|  |  | Horizon’s and IBKC’s named executive officers to the extent payable in accordance with the terms of their compensation agreements and other contractual arrangements even if the holders of First Horizon and/or IBKC common stock, respectively, do not approve the proposals to approve the merger-related executive compensation.

| Q: |  | What if I hold shares in both First Horizon and IBKC?
| A: |  | If you hold shares in both First Horizon common stock and IBKC common stock, you will receive separate packages of proxy materials. A vote cast as a holder of First Horizon common stock will not count as a vote cast as a holder of IBKC common stock, and a vote cast as a holder of IBKC common stock will not count as a vote cast as a holder of First Horizon common stock. Therefore, please submit separate proxies for your shares of First Horizon common stock and your shares of IBKC common stock.

| Q: |  | How can I vote my shares in person at my respective special meeting?
| A: |  | Record Holders. Shares held directly in your name as the holder of record of First Horizon or IBKC common stock may be voted in person at the First Horizon special meeting or the IBKC special meeting, as applicable. If you choose to vote your shares in person at the respective special meeting, please bring your enclosed proxy card and proof of identification.
|  |  | Shares in “street name.” Shares held in a brokerage or other account in “street name” may be voted in person by you only if you obtain a signed legal proxy from your bank, broker or other nominee giving you the right to vote the shares. If you choose to vote your shares in street name in person at the First Horizon special meeting or the IBKC special meeting, as applicable, please bring that signed legal proxy along with proof of identification.
|  |  | Even if you plan to attend the First Horizon special meeting or the IBKC special meeting, as applicable, First Horizon and IBKC recommend that you vote your shares in advance as described below so that your vote will be counted if you later decide not to or become unable to attend the respective special meeting.
|  |  | Additional information on attending the special meetings can be found under the section entitled “The First Horizon Special Meeting” on page 51 and under the section entitled “The IBKC Special Meeting” on page 58.

| Q: |  | How can I vote my shares without attending my respective special meeting?
| A: |  | Whether you hold your shares directly as the holder of record of First Horizon or IBKC or beneficially in “street name,” you may direct your vote by proxy without attending the First Horizon special meeting or the IBKC special meeting, as applicable.
|  |  | If you are a record holder of First Horizon common stock or IBKC common stock, you can vote your shares by proxy over the Internet, by telephone or by mail by following the instructions provided in the enclosed proxy card. If you hold shares beneficially in “street name,” you should follow the voting instructions provided by your bank, broker or other nominee.
|  |  | Additional information on voting procedures can be found under the section entitled “The First Horizon Special Meeting” on page 51 and under the section entitled “The IBKC Special Meeting” on page 58.

| Q: |  | What do I need to do now?
| A: |  | After carefully reading and considering the information contained in this document, please vote as soon as possible. If you hold shares of First Horizon common stock or IBKC common stock, please respond by completing, signing and dating the accompanying proxy card and returning it in the enclosed postage-paid envelope, or by submitting your proxy by telephone or through the Internet, as soon as possible so that your shares may be represented at your meeting.

|  |  | that if you hold shares beneficially in “street name,” you should follow the voting instructions provided by your bank, broker or other nominee.

| Q: |  | If my shares are held in “street name” by a broker, bank or other nominee, will my broker, bank or other nominee vote my shares for me?
| A: |  | No. Your bank, broker or other nominee cannot vote your shares without instructions from you. You should instruct your bank, broker or other nominee how to vote your shares in accordance with the instructions provided to you. Please check the voting form used by your bank, broker or other nominee.

| Q: |  | Why is my vote important?
| A: |  | Your failure to submit a proxy or vote in person, or failure to instruct your bank or broker how to vote, or abstention will have the same effect as a vote “AGAINST” approval of the IBKC merger proposal and the First Horizon merger proposal. The merger agreement must be approved by the affirmative vote of a majority of all the votes entitled to be cast on the First Horizon merger proposal by the holders of First Horizon common stock and by the affirmative vote of a majority of all the votes entitled to be cast on the IBKC merger proposal by the holders of IBKC common stock. The First Horizon charter amendment proposal must be approved by the affirmative vote of a majority of the votes cast on the First Horizon charter amendment proposal by the holders of First Horizon common stock. The First Horizon board of directors unanimously recommends that you vote “FOR” the First Horizon merger proposal and the First Horizon charter amendment proposal, and the IBKC board of directors unanimously recommends that you vote “FOR” the IBKC merger proposal.

| Q: |  | What will happen if I return my proxy card without indicating how to vote?
| A: |  | If you sign and return your proxy card without indicating how to vote on any particular proposal, the shares of First Horizon common stock represented by your proxy will be voted as recommended by the First Horizon board of directors with respect to such proposals or the shares of IBKC common stock represented by your proxy will be voted as recommended by the IBKC board of directors with respect to such proposals, as the case may be.

| Q: |  | Can I change my vote after I have delivered my proxy or voting instruction card?
| A: |  | If you directly hold shares of First Horizon common stock or IBKC common stock in your name as a record holder, you can change your vote at any time before your proxy is voted at your meeting. You can do this by:

| • |  | submitting a written statement that you would like to revoke your proxy to the corporate secretary of First Horizon or IBKC, as applicable;
| • |  | signing and returning a proxy card with a later date;
| • |  | attending the special meeting in person, notifying the corporate secretary and voting by ballot at the special meeting; or
| • |  | voting by telephone or the Internet at a later time.
|  |  | If your shares are held by a broker, bank or other nominee, you should contact your broker, bank or other nominee to change your vote.

| Q: |  | Will First Horizon be required to submit the First Horizon merger proposal and the First Horizon charter amendment proposal to its shareholders even if the First Horizon board of directors has withdrawn, modified or qualified its recommendation?
| A: |  | Yes. Unless the merger agreement is terminated before the First Horizon special meeting, First Horizon is required to submit the First Horizon merger proposal and the First Horizon charter amendment proposal to its shareholders even if the First Horizon board of directors has withdrawn or modified its recommendation.

| Q: |  | Will IBKC be required to submit the IBKC merger proposal to its shareholders even if the IBKC board of directors has withdrawn, modified or qualified its recommendation?
| A: |  | Yes. Unless the merger agreement is terminated before the IBKC special meeting, IBKC is required to submit the IBKC merger proposal to its shareholders even if the IBKC board of directors has withdrawn or modified its recommendation.

| Q: |  | Are holders of First Horizon common stock entitled to dissenters’ rights?
| A: |  | No. Holders of First Horizon common stock are not entitled to dissenters’ rights under the Tennessee Business Corporation Act (the “TBCA”). For more information, see the section entitled “The Merger—Appraisal or Dissenters’ Rights in the Merger” beginning on page 135.

| Q: |  | Are holders of IBKC common stock entitled to appraisal rights?
| A: |  | No. Holders of IBKC common stock are not entitled to appraisal rights under the LBCA. For more information, see the section entitled “The Merger—Appraisal or Dissenters’ Rights in the Merger” beginning on page 135.

| Q: |  | Are holders of IBKC preferred stock entitled to appraisal rights?
| A: |  | Holders of record of IBKC preferred stock are entitled to exercise appraisal rights in connection with the merger, provided the proper procedures of Part 13 of the LBCA are followed. The Depository Trust Company (“DTC”), as nominee for the depository, is the holder of record of the shares of IBKC preferred stock as of the date of this joint proxy statement/prospectus.
|  |  | The IBKC depositary shares are not a class or series of shares issued by IBKC and thus appraisal rights under Part 13 of the LBCA do not independently apply to the depositary shares. Accordingly, to direct the depository to exercise appraisal rights with respect to the IBKC preferred stock, holders of depositary shares will be required to follow the procedures provided by the depository with respect thereto and in accordance with requirements of Louisiana law.
|  |  | If you hold IBKC depositary shares and you wish to exercise appraisal rights in respect of the merger, IBKC requests that you complete the form of instruction to be provided to you (in accordance with the instructions set out on the form) and return it to your bank, broker or other nominee, as applicable, to direct the depository to exercise appraisal rights on your behalf following their usual procedures.
|  |  | A copy of Part 13 of the LBCA is attached as Annex E to this joint proxy statement/prospectus. Holders of IBKC preferred stock who desire to exercise appraisal rights, or holders of depositary shares who direct the depository to exercise appraisal rights, pursuant to Part 13 of the LBCA, are urged to consult a legal advisor before electing or attempting to exercise these rights.

| Q: |  | Are there any risks that I should consider in deciding whether to vote for the approval of the First Horizon merger proposal, the approval of the First Horizon charter amendment proposal or the approval of the IBKC merger proposal?
| A: |  | Yes. You should read and carefully consider the risk factors set forth in the section entitled “Risk Factors” beginning on page 41. You also should read and carefully consider the risk

11

|  |  | factors of First Horizon and IBKC contained in the documents that are incorporated by reference into this joint proxy statement/prospectus.

| Q: |  | What are the material U.S. federal income tax consequences of the merger to holders of IBKC common stock or IBKC preferred stock?
| A: |  | The merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Code and it is a condition to the respective obligations of First Horizon and IBKC to complete the merger that each of First Horizon and IBKC receives a legal opinion to that effect. Accordingly, the tax consequences of the merger to holders of IBKC common stock or IBKC preferred stock, as applicable, are as follows:

| • |  | with respect to dissenting holders of IBKC preferred stock, a holder who receives solely cash for shares of IBKC preferred stock and does not otherwise own any IBKC common stock will recognize gain or loss equal to the difference between the amount of cash received by a holder of IBKC preferred stock and such holder’s tax basis in such holder’s shares of IBKC preferred stock;
| • |  | a holder who receives solely shares of First Horizon common stock (or receives First Horizon common stock and cash solely in lieu of a fractional share) or rollover First Horizon preferred stock, as applicable, in exchange for shares of IBKC common stock or IBKC preferred stock, as applicable, generally will not recognize any gain or loss upon the merger, except with respect to the cash received in lieu of fractional share of First Horizon common stock;
| • |  | with respect to dissenting holders of IBKC preferred stock, a holder who receives both cash for shares of IBKC preferred stock and shares of First Horizon common stock in respect of IBKC common stock, such cash may be allocated entirely to IBKC preferred stock and such dissenting holder will recognize gain (but not loss) equal to the difference between the amount of such cash received by a holder of IBKC preferred stock and such holder’s tax basis in such holder’s shares of IBKC preferred stock.

The United States federal income tax consequences described above may not apply to all holders of IBKC common stock or IBKC preferred stock. Your tax consequences will depend on your individual situation. Accordingly, we strongly urge you to consult your tax advisor for a full understanding of the particular tax consequences of the merger to you.

| Q: |  | When is the merger expected to be completed?
| A: |  | First Horizon and IBKC expect the merger to close in the second quarter of 2020. However, neither First Horizon nor IBKC can predict the actual date on which the merger will be completed, or if the merger will be completed at all, because completion is subject to conditions and factors outside the control of both companies. First Horizon and IBKC must first obtain the approval of holders of First Horizon common stock and holders of IBKC common stock for the merger and First Horizon must obtain approval of the First Horizon charter amendment proposal, as well as obtain necessary regulatory approvals and satisfy certain other closing conditions.

| Q: |  | What are the conditions to complete the merger?
| A: |  | The obligations of First Horizon and IBKC to complete the merger are subject to the satisfaction or waiver of certain closing conditions contained in the merger agreement, including the receipt of required regulatory approvals and the expiration of all statutory waiting periods without the imposition of any materially burdensome regulatory condition, tax opinions, approval by First Horizon shareholders of both the First Horizon merger proposal and the First Horizon charter amendment proposal and approval by IBKC stockholders of the IBKC merger proposal. For more information, see “The Merger Agreement—Conditions to Complete the Merger” beginning on page 154.

12

| Q: |  | What happens if the merger is not completed?
| A: |  | If the merger is not completed, neither holders of IBKC common stock nor holders of IBKC preferred stock will receive any consideration for their shares of IBKC common stock or IBKC preferred stock, respectively, in connection with the merger. Instead, IBKC will remain an independent public company, IBKC common stock and IBKC depositary shares will continue to be listed and traded on NASDAQ, and First Horizon will not complete the issuance of shares of First Horizon common stock or rollover First Horizon preferred stock pursuant to the merger agreement. In addition, if the merger agreement is terminated in certain circumstances, a termination fee of $156 million will be payable by either First Horizon or IBKC, as applicable. See “The Merger Agreement—Termination Fee” beginning on page 156 for a more detailed discussion of the circumstances under which a termination fee will be required to be paid.

| Q: |  | What happens if I sell my shares after the applicable record date but before my company’s special meeting?
| A: |  | Each of the First Horizon and IBKC record date is earlier than the date of the First Horizon special meeting and the IBKC special meeting, as applicable, and earlier than the date that the merger is expected to be completed. If you sell or otherwise transfer your shares of First Horizon common stock or IBKC common stock, as applicable, after the applicable record date but before the date of the applicable special meeting, you will retain your right to vote at such special meeting (provided that such shares remain outstanding on the date of such special meeting), but, with respect to the IBKC common stock, you will not have the right to receive the merger consideration to be received by IBKC shareholders in connection with the merger. In order to receive the merger consideration, you must hold your shares of IBKC common stock through the completion of the merger.

| Q: |  | Should I send in my stock certificates now?
| A: |  | No. Please do not send in your stock certificates with your proxy. After the merger is completed, an exchange agent selected by First Horizon and IBKC (the “exchange agent”) will send you instructions for exchanging IBKC stock certificates for the consideration to be received in the merger. See “The Merger Agreement—Conversion of Shares; Exchange of IBKC Stock Certificates” beginning on page 144.

| Q: |  | What should I do if I receive more than one set of voting materials for the same special meeting?
| A: |  | If you hold shares of First Horizon common stock or IBKC common stock in “street name” and also directly in your name as a holder of record or otherwise or if you hold shares of First Horizon common stock or IBKC common stock in more than one (1) brokerage account, you may receive more than one (1) set of voting materials relating to the same special meeting.
|  |  | Record Holders. For shares held directly, please complete, sign, date and return each proxy card (or cast your vote by telephone or Internet as provided on each proxy card) or otherwise follow the voting instructions provided in this joint proxy statement/prospectus in order to ensure that all of your shares of First Horizon common stock or IBKC common stock are voted.
|  |  | Shares in “street name.” For shares held in “street name” through a bank, broker or other nominee, you should follow the procedures provided by your bank, broker or other nominee to vote your shares.

| Q: |  | Who can help answer my questions?
| A: |  | First Horizon shareholders: If you have any questions about the merger or how to submit your proxy or voting instruction card, or if you need additional copies of this document or the enclosed proxy card or voting instruction card, you should contact First Horizon’s proxy solicitor, Morrow Sodali LLC, by calling toll-free at (800) 662-5200.

| Q: |  | Where can I find more information about First Horizon and IBKC?
| A: |  | You can find more information about First Horizon and IBKC from the various sources described under “Where You Can Find More Information” beginning on page 218.

| Q: |  | What is householding and how does it affect me?
| A: |  | The SEC permits companies to send a single set of proxy materials to any household at which two or more shareholders reside, unless contrary instructions have been received, but only if the applicable shareholders provide advance notice and follow certain procedures. In such cases, each shareholder continues to receive a separate notice of the meeting and proxy card. Certain brokerage firms may have instituted householding for beneficial owners of First Horizon common stock and IBKC common stock, as applicable, held through brokerage firms. If your family has multiple accounts holding First Horizon common stock or IBKC common stock, as applicable, you may have already received a householding notification from your broker. Please contact your broker directly if you have any questions or require additional copies of this joint proxy statement/prospectus. The broker will arrange for delivery of a separate copy of this joint proxy statement/prospectus promptly upon your written or oral request. You may decide at any time to revoke your decision to household, and thereby receive multiple copies.

The Merger and the Merger Agreement (pages 66 and 141)

The terms and conditions of the merger are contained in the merger agreement, a copy of which is attached as Annex A to this joint proxy statement/prospectus. You are encouraged to read the merger agreement carefully and in its entirety, as it is the primary legal document that governs the merger.

Subject to the terms and conditions of the merger agreement, at the completion of the merger, IBKC will merge with and into First Horizon, with First Horizon as the surviving corporation in a merger of equals. Following the completion of the merger, IBERIABANK, a subsidiary of IBKC, will merge with and into First Horizon Bank, a subsidiary of First Horizon, with First Horizon Bank as the surviving bank in the bank merger. Following the merger, IBKC common stock and IBKC depositary shares will be delisted from the NASDAQ, deregistered under the Exchange Act and will cease to be publicly traded.

Merger Consideration (page 142)

In the merger, holders of IBKC common stock will receive 4.584 shares of First Horizon common stock for each share of IBKC common stock they hold immediately prior to the effective time. First Horizon will not issue any fractional shares of First Horizon common stock in the merger. Holders of IBKC common stock who would otherwise be entitled to a fraction of a share of First Horizon common stock in the merger will instead receive, for the fraction of a share, an amount in cash (rounded to the nearest cent) based on the First Horizon closing share value.

First Horizon common stock is listed on the NYSE under the symbol “FHN,” and IBKC common stock is listed on the NASDAQ under the symbol “IBKC.” The following table shows the closing sale prices of First Horizon common stock and IBKC common stock as reported on the NYSE and NASDAQ, as applicable, on November 1, 2019, the last full trading day before the public announcement of the merger agreement, and on [ ], 2020, the last practicable trading day before the date of this joint proxy statement/prospectus. This table also shows the implied value of the merger consideration to be issued in exchange for each share of IBKC common stock, which was calculated by multiplying the closing price of First Horizon common stock on those dates by the exchange ratio of 4.584.

Treatment of IBKC Preferred Stock and IBKC Depositary Shares (page 135)

In the merger, each share of IBKC series B preferred stock, IBKC series C preferred stock and IBKC series D preferred stock, in each case issued and outstanding immediately prior to the effective time and excluding dissenting shares, will be converted into the right to receive one (1) share of First Horizon series B preferred stock, First Horizon series C preferred stock and First Horizon series D preferred stock, respectively. The rollover First Horizon preferred stock will have terms that are the same as the terms of the applicable series of outstanding IBKC preferred stock, taking into account that IBKC will not be the surviving entity in the merger and, with respect to the IBKC series B preferred stock, taking into account that the optional redemption date for the First Horizon series B preferred stock may be deferred until the first dividend payment date that is at least five (5) years from the closing date.

Each outstanding share of IBKC series B preferred stock, IBKC series C preferred stock and IBKC series D preferred stock is presently represented by IBKC depositary shares. Upon completion of the merger, First Horizon will assume the obligations of IBKC under the applicable deposit agreements. Each IBKC depositary share (other than in respect of dissenting shares of IBKC preferred stock) will then become a rollover First Horizon depositary share and thereafter represent interests in shares of rollover First Horizon preferred stock. The IBKC depositary shares representing a 1/400th interest in a share of IBKC series B preferred stock, IBKC series C preferred stock and IBKC series D preferred stock are currently listed on the NASDAQ under the symbol “IBKCP,” “IBKCO” and “IBKCN,” respectively. The rollover First Horizon depositary shares are expected to be listed on the NYSE upon completion of the merger.

IBKC Equity Awards Granted On or After November 3, 2019

Any IBKC equity awards are granted on or after November 3, 2019 will be converted into First Horizon equity awards with the number of shares of First Horizon common stock and exercise price, if applicable, adjusted based on the exchange ratio.

Opinions of IBKC’s Financial Advisors (page 88)

Opinion of Keefe, Bruyette & Woods, Inc.

In connection with the merger, IBKC’s financial advisor, Keefe, Bruyette & Woods, Inc. (“KBW”), delivered a written opinion, dated November 3, 2019, to the IBKC board of directors as to the fairness, from a financial point of view and as of the date of the opinion, to the holders of IBKC common stock of the exchange ratio in the proposed merger. The full text of the opinion, which describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW in preparing the opinion, is attached as Annex C to this document. The opinion was for the information of, and was directed to, the IBKC board (in its capacity as such) in connection with its consideration of the financial terms of the merger. The opinion does not address the underlying business decision of IBKC to engage in the merger or enter into the merger agreement or constitute a recommendation to the IBKC board of directors in connection with the merger, and it does not constitute a recommendation to any holder of IBKC common stock or any shareholder of any other entity as to how to vote or act in connection with the merger or any other matter.

Pursuant to an engagement letter between IBKC and KBW, IBKC agreed to pay KBW a cash fee equal to 0.70% of the aggregate merger consideration, which fee is estimated to be approximately $29 million, based on the closing share price of First Horizon common stock on November 1, 2019, $4,000,000 of which became payable upon IBKC entering into the merger agreement and the balance of which is contingent upon the completion of the merger.

statement/prospectus as Annex D. The summary of the Goldman Sachs opinion contained in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of Goldman Sachs’ written opinion. Goldman Sachs’ advisory services and opinion were provided for the information and assistance of the IBKC board of directors in connection with its consideration of the merger and the opinion does not constitute a recommendation as to how any holder of IBKC common stock should vote with respect to the merger or any other matter.

Pursuant to an engagement letter between IBKC and Goldman Sachs, IBKC has agreed to pay Goldman Sachs for its services in connection with the merger a fee that is estimated to be approximately $19.6 million, based on the closing share price of First Horizon common stock on November 1, 2019. $2.5 million of Goldman Sachs’ fee became payable upon the execution of the merger agreement and the remainder of Goldman Sachs’ fee will become payable upon completion of the merger.

Appraisal or Dissenters’ Rights in the Merger (page 135)

Holders of First Horizon common stock are not entitled to dissenters’ rights under the TBCA and holders of IBKC common stock are not entitled to appraisal rights under the LBCA. For more information, see “The Merger—Appraisal or Dissenters’ Rights in the Merger” beginning on page 135.

Holders of record of IBKC preferred stock are entitled to exercise appraisal rights in connection with the merger, provided the proper procedures of Part 13 of the LBCA are followed. DTC, as nominee for the depository, is the holder of record of the shares of IBKC preferred stock as of the date of this joint proxy statement/prospectus.

The IBKC depositary shares are not a class or series of shares issued by IBKC and thus appraisal rights under Part 13 of the LBCA do not independently apply to the depositary shares. Accordingly, to exercise or to direct the depository to exercise appraisal rights with respect to the IBKC preferred stock, holders of depositary shares will be required to follow the procedures provided by the depository with respect thereto and in accordance with requirements of Louisiana law.

If you hold IBKC depositary shares and you wish to exercise appraisal rights in respect of the merger, IBKC requests that you complete the form of instruction provided to you (in accordance with the instructions set out on the form) and return it to your bank, broker or other nominee, as applicable, to direct the depository to exercise appraisal rights on your behalf following their usual procedures. Although holders of depositary shares may attend the IBKC special meeting, such holders may not exercise appraisal rights with respect to, or vote, as applicable, the shares of IBKC preferred stock represented by such depositary shares in person at the IBKC special meeting.

A copy of Part 13 of the LBCA is attached as Annex E to this joint proxy statement/prospectus. Holders of IBKC preferred stock who desire to exercise appraisal rights, or holders of depositary shares who direct the depository to exercise appraisal rights, pursuant to Part 13 of the LBCA are urged to consult a legal advisor before electing or attempting to exercise these rights.

Under Part 13 of the LBCA, the holders of IBKC common stock will not be entitled to appraisal rights in connection with the merger if, on the record date for the IBKC special meeting, IBKC’s shares are traded in an organized market that has at least two thousand (2,000) shareholders and a market value of at least $20 million. IBKC common stock is currently listed on the NASDAQ, a national securities exchange, and is expected to continue to be so listed on the record date for the IBKC special meeting. Accordingly, the holders of IBKC common stock are not entitled to any appraisal rights in connection with the merger.

21

Holders of IBKC preferred stock have a right to demand payment in cash of the “fair value” of their shares, as that term is defined in the LBCA. Shareholders who receive a fair value cash payment will not be entitled to receive any shares of rollover First Horizon preferred stock. Part 13 of the LBCA sets forth the rights of IBKC preferred shareholders who wish to demand appraisal for their shares. A summary of the material terms of the statutory procedures to be followed by a holder of IBKC preferred stock in order to perfect appraisal rights under the LBCA can be found under “The Merger—Appraisal or Dissenters’ Rights in the Merger—Holders of IBKC Preferred Stock,” beginning on page 136. Shareholders who do not properly follow appraisal rights procedures will receive the merger consideration provided under the merger agreement if the merger is completed. A copy of Part 13 of the LBCA is attached as Annex E to this joint proxy statement/prospectus.

Interests of Certain First Horizon Directors and Executive Officers in the Merger (page 113)

In considering the First Horizon board of directors’ recommendation to vote to approve the First Horizon merger proposal, holders of First Horizon common stock should be aware that First Horizon’s directors and executive officers may have interests in the merger that are different from, or in addition to, those of holders of First Horizon common stock generally and that may create potential conflicts of interest. These interests include:

| • |  | D. Bryan Jordan and First Horizon have entered into a letter agreement with respect to the terms of Mr. Jordan’s employment following the closing. Pursuant to the letter agreement, Mr. Jordan will resign as Chairman on the closing date and continue to serve as the President and Chief Executive Officer of the combined company and the combined bank. On the chairman succession date (as such term is defined under “The Merger—Interests of Certain IBKC Directors and Executive Officers in the Merger—Chairman Letter Agreement of Mr. Byrd” beginning on page 121), Mr. Jordan will be reappointed as Chairman of the combined company and the combined bank, as further described under “The Merger—Governance of the Combined Company After the Merger” beginning on page 129. The letter agreement also provides for the waiver of Mr. Jordan’s right to terminate his employment for “good reason” under Mr. Jordan’s Change in Control Severance Agreement with First Horizon (the “Jordan CIC agreement”) as a result of Mr. Jordan’s resignation as Chairman or the reassignment of certain duties, so long as Mr. Jordan remains President and Chief Executive Officer and is reappointed as Chairman on the chairman succession date.
| • |  | Each of William C. Losch III, David T. Popwell and one (1) additional executive officer who is not a named executive officer have entered into letter agreements (the “executive letter agreements”) with First Horizon that provide for the grant of closing incentive restricted stock awards in consideration for a waiver of the executive’s rights to terminate employment for “good reason” under the executive’s Change in Control Severance Agreement with First Horizon as a result of the executive’s new role at the combined company and any corresponding change in duties and responsibilities. The restricted stock awards will vest in full on the first anniversary of the closing date and will be forfeited upon any termination of employment other than termination by the surviving entity or surviving bank that is not for “cause.” All restricted stock awards also will be forfeited if the merger does not close and will be subject to repayment and recovery in full if the executive materially violates restrictive covenants in the letter agreement. The amounts of the closing incentive awards are $1,250,000 for Mr. Losch, $1,400,000 for Mr. Popwell and $863,000 for the executive officer who is not a named executive officer.

| • |  | In connection with the merger, First Horizon intends to establish a retention program to promote retention and to incentivize efforts to consummate the merger and effectuate the integration and conversion. Awards under this retention program will be in the form of cash or full-value equity awards and will be contingent upon the recipient’s continued employment with the combined company through the first anniversary of the effective time, provided that

22

|  |  | such awards will vest or be payable (as applicable) upon a qualifying termination of employment. First Horizon’s executive officers (including certain of First Horizon’s named executive officers), other than Mr. Jordan and the officers who entered into the executive letter agreements described above, will be eligible to participate in this retention program.
| • |  | First Horizon’s executive officers are each party to a Change in Control Severance Agreement with First Horizon that provides for certain benefits upon a termination by First Horizon other than for “cause,” disability or retirement, or upon a termination by the executive officer for “good reason,” within thirty-six (36) months following a change in control event, such as the merger.
| • |  | At closing, certain of First Horizon’s directors and executive officers will continue to serve as directors or executive officers, as applicable, of the combined company.
| • |  | First Horizon’s directors and executive officers are entitled to continued indemnification and insurance coverage.

The First Horizon board of directors was aware of and considered these respective interests when deciding to adopt the merger agreement. For more information, see the section entitled “The Merger—Interests of Certain First Horizon Directors and Executive Officers in the Merger” beginning on page 113.

Interests of Certain IBKC Directors and Executive Officers in the Merger (page 119)

In considering the recommendation of the IBKC board of directors to vote for the IBKC merger proposal, holders of IBKC common stock should be aware that the directors and executive officers of IBKC may have interests in the merger that are different from, or in addition to, the interests of holders of IBKC common stock generally and that may create potential conflicts of interest.

For the subsequent thirty-six (36)-month period, Mr. Byrd will serve as a consultant to the combined company and the combined bank and will receive an annual consulting fee equal to (i) $3,750,000 for the first two (2) years and (ii) $3,500,000 for the third (3rd) year. As of the closing date, the combined company and the combined bank will grant Mr. Byrd a one-time cash integration and continuity award in the amount of $5,000,000, payable in quarterly installments over five (5) years. Mr. Byrd has agreed to be bound by certain restrictive covenants, including non-competition and non-solicitation covenants, for the five (5)-year period following the closing date. He will also be subject to indefinite non-disparagement and confidentiality covenants.
| • |  | Mr. Byrd, IBKC and IBERIABANK have entered into a letter agreement, providing for the grant of a closing incentive restricted stock award with a grant date value of $5,000,000 that will vest on the six (6)-month anniversary of the completion of the merger.

|  |  | termination of employment other than a termination for “just cause” or resignation without “good reason.” All such restricted stock awards will be forfeited if the merger does not close and will be subject to repayment and recovery in full if the executive materially violates any of the restrictive covenants outlined in the letter agreements. The amounts of the closing incentive awards are $1,350,000 for Mr. Restel, $1,400,000 for Mr. Brown and $1,688,000 (in the aggregate) for the other two (2) executive officers who are not named executive officers.
| • |  | In connection with the merger, IBKC intends to establish a retention program to promote retention and to incentivize efforts to consummate the merger and effectuate the integration and conversion. Awards under these retention programs will be in the form of cash or full-value equity awards and will be contingent upon the recipient’s continued employment with the combined company through the first (1 st) anniversary of the effective time, provided that such awards will vest or be payable (as applicable) upon a qualifying termination of employment. IBKC’s executive officers (including certain of IBKC’s named executive officers), other than Mr. Byrd and the executive officers who entered into the letter agreements described above, will be eligible to participate in this retention program.
| • |  | Unvested IBKC equity awards granted prior to the execution of the merger agreement held by executive officers that would otherwise be subject to vesting conditions will, in accordance with the terms and conditions applicable to such awards prior to the execution of the merger agreement, vest on the closing. IBKC equity awards granted following the execution of the merger agreement and converted into First Horizon equity awards will generally be eligible to vest upon a termination of the holder without “cause” or the holder’s resignation for “good reason” following the closing.
| • |  | At closing, certain of IBKC’s directors and executive officers will continue to serve as directors or executive officers, as applicable, of the combined company.
| • |  | The restricted stock awards held by the IBKC non-employee directors that would otherwise vest on the first anniversary of the grant date will, in accordance with the terms and conditions applicable to such awards prior to the execution of the merger agreement, vest on the closing.
| • |  | IBKC directors and executive officers are entitled to continued indemnification and insurance coverage under the merger agreement.

| • |  | all regulatory authorizations, consents, orders and approvals from the Federal Reserve Board and the TDFI or such other approvals the failure of which to be obtained would reasonably be expected to have, individually or in the aggregate, a material adverse effect (the “requisite regulatory approvals”) having been obtained and remaining in full force and effect, and all statutory waiting periods in respect thereof having expired or been terminated, without the imposition of any materially burdensome regulatory condition;
| • |  | effectiveness of the registration statement of which this joint proxy statement/prospectus is part;

The merger agreement may be terminated at any time prior to the completion of the merger, whether before or after the receipt of the required vote to approve the merger agreement by First Horizon shareholders or IBKC shareholders, in the following circumstances:

| • |  | by mutual written consent of First Horizon and IBKC;
| • |  | by either First Horizon or IBKC if any governmental entity that must grant a requisite regulatory approval has denied approval of the merger or the bank merger and such denial has become final and nonappealable or any governmental entity of competent jurisdiction has issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the merger or the bank merger, unless the failure to obtain a requisite regulatory approval is due to the failure of the party seeking to terminate the merger agreement to perform or observe its obligations, covenants and agreements under the merger agreement;
| • |  | by either First Horizon or IBKC if the merger has not been completed on or before November 3, 2020 (the “termination date”), unless the failure of the merger to be completed by such date is due to the failure of the party seeking to terminate the merger agreement to perform or observe its obligations, covenants and agreements under the merger agreement;
| • |  | by either First Horizon or IBKC (provided that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained in

27

|  |  | the merger agreement) if there is a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty ceases to be true) set forth in the merger agreement on the part of the other party which either individually or in the aggregate would constitute, if occurring or continuing on the date the merger is completed, the failure of a closing condition of the terminating party and which is not cured within forty-five (45) days following written notice to the party committing such breach, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the termination date);
| • |  | by IBKC, if: (1) the First Horizon board of directors (i) withholds, withdraws, modifies or qualifies in a manner adverse to IBKC its recommendation in this joint proxy statement/prospectus that the holders of First Horizon common stock approve the merger agreement (the “First Horizon board recommendation”); (ii) fails to make the First Horizon board recommendation in this joint proxy statement/prospectus; (iii) adopts, approves, recommends or endorses an acquisition proposal (as defined below in “The Merger Agreement—Agreement Not to Solicit Other Offers” beginning on page 153) or publicly announces an intention to adopt, approve, recommend or endorse an acquisition proposal; (iv) fails to publicly and without qualification (A) recommend against any acquisition proposal or (B) reaffirm the First Horizon board recommendation within ten (10) business days (or such fewer number of days as remains prior to the First Horizon special meeting) after an acquisition proposal is made public or any request by IBKC to do so; or (v) publicly proposes to do any of the foregoing; or (2) First Horizon or the First Horizon board of directors breaches in any material respect its obligations relating to non-solicitation of acquisition proposals or its obligations related to shareholder approval and the First Horizon board recommendation; or
| • |  | by First Horizon, if: (1) the IBKC board of directors (i) withholds, withdraws, modifies or qualifies in a manner adverse to First Horizon its recommendation in this joint proxy statement/prospectus that the holders of IBKC common stock and holders of IBKC preferred stock approve the merger agreement (the “IBKC board recommendation”); (ii) fails to make the IBKC board recommendation in this joint proxy statement/prospectus; (iii) adopts, approves, recommends or endorses an acquisition proposal or publicly announces an intention to adopt, approve, recommend or endorse an acquisition proposal; (iv) fails to publicly and without qualification (A) recommend against any acquisition proposal or (B) reaffirm the IBKC board recommendation within ten (10) business days (or such fewer number of days as remains prior to the IBKC special meeting) after an acquisition proposal is made public or any request by First Horizon to do so; or (v) publicly proposes to do any of the foregoing; or (2) IBKC or the IBKC board of directors breaches in any material respect its obligations relating to non-solicitation of acquisition proposals or its obligations related to shareholder approval and the IBKC board recommendation.

Neither First Horizon nor IBKC is permitted to terminate the merger agreement as a result of any increase or decrease in the market price of First Horizon common stock or IBKC common stock.

Termination Fee (page 156)

If the merger agreement is terminated under certain circumstances, including circumstances involving alternative acquisition proposals and changes in the recommendation of IBKC’s or First Horizon’s respective boards, IBKC or First Horizon may be required to pay a termination fee to the other equal to $156 million.

Accounting Treatment (page 132)

First Horizon and IBKC each prepare their respective financial statements in accordance with accounting principles generally accepted in the United States (“GAAP”). The merger will be

28

accounted for using the acquisition method of accounting, and First Horizon will be treated as the accounting acquirer.

The Rights of Holders of IBKC Common Stock Will Change as a Result of the Merger (page 200)

The rights of holders of IBKC common stock are governed by Louisiana law and by the articles of incorporation and bylaws of IBKC. In the merger, holders of IBKC common stock will become holders of common stock of First Horizon, and their rights will be governed by Tennessee law and the First Horizon charter, as amended by the First Horizon charter amendment, and the bylaws of First Horizon, as amended by the First Horizon bylaw amendment. Holders of IBKC common stock will have different rights once they become holders of common stock of First Horizon due to differences between the IBKC governing documents and Louisiana law, on the one hand, and the First Horizon governing documents and Tennessee law, on the other hand. These differences are described in more detail under the section entitled “Comparison of Shareholders’ Rights” beginning on page 200.

Listing of First Horizon Common Stock and Rollover First Horizon Depositary Shares in Respect of Rollover First Horizon Preferred Stock; Delisting and Deregistration of IBKC Common Stock and Depositary Shares in Respect of IBKC Preferred Stock (page 172)

The shares of First Horizon common stock and rollover First Horizon depositary shares to be issued in the merger will be listed for trading on the NYSE. Following the merger, shares of First Horizon common stock will continue to be traded on the NYSE. In addition, following the merger, IBKC common stock and IBKC depositary shares will be delisted from the NASDAQ and deregistered under the Exchange Act.

The First Horizon Special Meeting (page 51)

The First Horizon special meeting will be held at [ ] on [ ], 2020 at [ ], local time. At the First Horizon special meeting, holders of First Horizon common stock will be asked to vote on the following matters:

| • |  | approve the First Horizon merger proposal;
| • |  | approve the First Horizon charter amendment proposal;
| • |  | approve the First Horizon compensation proposal; and
| • |  | approve the First Horizon adjournment proposal.

You may vote at the First Horizon special meeting if you owned shares of First Horizon common stock at the close of business on February 24, 2020. As of February 24, 2020, there were [ ] shares of First Horizon common stock outstanding, of which less than [ ] percent ([ ]%) were owned and entitled to be voted by First Horizon directors and executive officers and their affiliates. We currently expect that First Horizon’s directors and executive officers will vote their shares in favor of the First Horizon merger proposal and the First Horizon charter amendment proposal, although none of them has entered into any agreements obligating them to do so.

The First Horizon merger proposal will be approved if a majority of all the votes entitled to be cast on the proposal by the holders of First Horizon common stock are voted in favor of the proposal. The First Horizon charter amendment proposal, the First Horizon compensation proposal and the First Horizon adjournment proposal will each be approved if a majority of the votes cast at the First Horizon special meeting are voted in favor of such proposal. If you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the First Horizon special meeting or fail to instruct your bank, broker or other nominee how to vote with respect to the First Horizon merger proposal, it will have the same effect as a vote “AGAINST” the First Horizon merger proposal.

special meeting or fail to instruct your bank or broker how to vote with respect to the First Horizon charter amendment proposal, the First Horizon compensation proposal or the First Horizon adjournment proposal, you will not be deemed to have cast a vote with respect to the First Horizon charter amendment proposal, the First Horizon compensation proposal or the First Horizon adjournment proposal, as applicable, and it will have no effect on the applicable proposal.

The IBKC Special Meeting (page 58)

The IBKC special meeting will be held at [ ] on [ ], 2020, at [ ], local time. At the IBKC special meeting, holders of IBKC common stock will be asked to vote on the following matters:

| • |  | approve the IBKC merger proposal;
| • |  | approve the IBKC compensation proposal; and
| • |  | approve the IBKC adjournment proposal.

You may vote at the IBKC special meeting if you owned shares of IBKC common stock at the close of business on February 24, 2020. As of February 24, 2020, there were [ ] shares of IBKC common stock outstanding, of which less than [ ] percent ([ ]%) were owned and entitled to be voted by IBKC directors and executive officers and their affiliates. We currently expect that IBKC’s directors and executive officers will vote their shares in favor of the IBKC merger proposal, although none of them has entered into any agreements obligating them to do so.

The IBKC merger proposal will be approved if a majority of all the votes entitled to be cast on the IBKC merger proposal by the holders of IBKC common stock are voted in favor of such proposal. The IBKC compensation proposal will be approved if a majority of the votes cast by the holders of IBKC common stock at the IBKC special meeting are voted in favor of such proposal. The IBKC adjournment proposal will be approved if the affirmative vote of a majority of the votes cast by holders of IBKC common stock are voted in favor of the proposal. If you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the IBKC special meeting or fail to instruct your bank, broker or other nominee how to vote with respect to the IBKC merger proposal, it will have the same effect as a vote “AGAINST” the IBKC merger proposal. If you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the IBKC special meeting or fail to instruct your bank, broker or other nominee how to vote with respect to the IBKC compensation proposal, you will not be deemed to have cast a vote with respect to the IBKC compensation proposal and it will have no effect on the IBKC compensation proposal. If you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the IBKC special meeting or fail to instruct your bank, broker or other nominee how to vote with respect to the IBKC adjournment proposal, you will not be deemed to have cast a vote with respect to the IBKC adjournment proposal and it will have no effect on the IBKC adjournment proposal.

Litigation Relating to the Merger (page 139)

Following the public announcement of the merger agreement, purported stockholders of IBKC filed a putative class action lawsuit and three individual lawsuits against IBKC, the members of the IBKC board of directors, and in the case of the putative class action, against First Horizon. Two of the individual lawsuits were filed in the United States District Court for the Eastern District of New York (Hertz v. IBERIABANK et al., No. 1:20-cv-00267 (filed Jan. 16, 2020); Cooksey v. IBERIABANK et al., No. 1:20-cv-00431 (filed Jan. 26, 2020)) and the third was filed in the United States District Court for the Southern District of New York, (Wang v. IBERIABANK, et al., No. 1:20-cv-00105 (filed on Jan. 6, 2020)). The putative class action was filed in the United States District Court for the District of Delaware (Parshall v. IBERIABANK et al., No. 1:20-cv-00027 (Jan. 8, 2020)). The complaints contain similar allegations contending, among other things, that the registration statement on Form S-4 misstated or failed to disclose certain allegedly material

SELECTED UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL DATA

The following table shows unaudited pro forma financial information about the financial condition and results of operations, including per share data, after giving effect to the merger between First Horizon and IBKC as well as the purchase of certain branches of SunTrust Bank by First Horizon (the “SunTrust Purchase”) and other pro forma adjustments. The unaudited pro forma financial information assumes that the IBKC merger and the SunTrust Purchase are accounted for under the acquisition method of accounting, and the assets and liabilities of IBKC and the purchased branches of SunTrust Bank will generally be recorded by First Horizon at their respective fair values as of the date the transactions were or are (as applicable) completed. The unaudited pro forma combined balance sheet gives effect to the transactions as if the transactions had occurred on December 31, 2019. The unaudited pro forma combined income statement for the year ended December 31, 2019, gives effect to the transactions as if the transactions had become effective at January 1, 2019. The unaudited selected pro forma combined financial information has been derived from and should be read in conjunction with the consolidated financial statements and related notes of First Horizon, which are incorporated in this joint proxy statement/prospectus by reference, the consolidated financial statements and related notes of IBKC, which are incorporated in this joint proxy statement/prospectus by reference, and the more detailed unaudited pro forma condensed combined financial information, including the notes thereto, appearing elsewhere in this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 218 and “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 163.

The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and does not indicate the financial results of the combined company had the companies actually been combined at the beginning of the period presented, nor the impact of possible business model changes. The unaudited pro forma condensed combined financial information also does not consider any potential effects of changes in market conditions on revenues, expense efficiencies, asset dispositions, and share repurchases, among other factors, including those discussed in the section entitled “Risk Factors” beginning on page 41. In addition, as explained in more detail in the accompanying notes to the “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 163, the preliminary allocations of the pro forma purchase prices reflected in the unaudited pro forma condensed combined financial information are subject to adjustment and may vary materially from the actual purchase price allocations that will be recorded upon completion of the merger and the SunTrust Purchase.

COMPARATIVE HISTORICAL AND UNAUDITED PRO FORMA PER SHARE DATA

The historical per share data for First Horizon common stock and IBKC common stock below has been derived from the audited consolidated financial statements of each of First Horizon and IBKC as of and for the year ended December 31, 2019, which is incorporated by reference herein.

The unaudited pro forma combined per share data set forth below gives effect to the merger as if it had occurred on January 1, 2019, the beginning of the earliest period presented, in the case of continuing net income per share data, and as of December 31, 2019 in the case of book value per share data, assuming that each outstanding share of IBKC common stock had been converted into shares of First Horizon common stock based on the exchange ratio of 4.584 shares of First Horizon common stock for each share of IBKC common stock. The unaudited pro forma combined per share data has been derived from the audited consolidated financial statements for each of First Horizon and IBKC as of and for the year ended December 31, 2019.

The unaudited pro forma combined per share data has been derived using the acquisition method of accounting. See “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 163 for more information. Accordingly, the pro forma adjustments reflect the assets and liabilities of IBKC and the purchased branches of SunTrust Bank at their preliminary estimated fair values. Differences between these preliminary estimates and the final values in acquisition accounting will occur and these differences could have a material impact on the unaudited pro forma combined per share information set forth below.

The unaudited pro forma combined per share data does not purport to represent the actual results of operations that the combined company would have achieved had the merger been completed during these periods or to project the future results of operations that the combined company may achieve after the merger and asset purchase.

The unaudited pro forma combined per share equivalent data set forth below shows the effect of the merger from the perspective of a holder of IBKC common stock. The information was calculated by multiplying the unaudited pro forma combined per share data by the exchange ratio of 4.584.

You should read the information below in conjunction with the selected consolidated historical financial data included elsewhere in this joint proxy statement/prospectus and the historical consolidated financial statements of First Horizon and IBKC and related notes that have been filed with the SEC, certain of which are incorporated by reference herein. See “Selected Consolidated Historical Financial Data of First Horizon”, “Selected Consolidated Historical Financial Data of IBKC” and “Where You Can Find More Information” beginning on pages 32, 34, and 218, respectively. The unaudited pro forma combined per share data and the unaudited pro forma combined per share equivalent data has been derived from, and should be read in conjunction with, the unaudited pro forma combined financial information and related notes included in this joint proxy statement/prospectus. See “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 163, which are based on and should be read in conjunction with (i) the historical audited consolidated financial statements of First Horizon and the related notes included in First Horizon’s Annual Report on Form 10-K for the year ended December 31, 2019 which is incorporated by reference herein, and (ii) the historical audited consolidated financial statements of IBKC and the related notes included in IBKC’s Annual Report on Form 10-K for the year ended December 31, 2019 and 2018 which is incorporated by reference herein.

Except as required by applicable law, neither First Horizon nor IBKC undertakes to update these forward-looking statements to reflect facts, circumstances, assumptions or events that occur after the date the forward-looking statements are made.

For additional information about factors that could cause actual results to differ materially from those described in the forward-looking statements, please see the reports that First Horizon and IBKC have filed with the SEC as described under “Where You Can Find More Information” beginning on page 218.

We expressly qualify in their entirety all forward-looking statements attributable to either of us or any person acting on our behalf by the cautionary statements contained or referred to in this joint proxy statement/prospectus.

RISK FACTORS

In addition to the other information contained in or incorporated by reference into this joint proxy statement/prospectus, including the matters addressed under the caption “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 39, you should carefully consider the following risk factors in deciding whether to vote for the approval of the merger agreement and, for the First Horizon shareholders, the approval of the First Horizon charter amendment proposal.

Because the market price of First Horizon common stock may fluctuate, holders of IBKC common stock cannot be certain of the market value of the merger consideration they will receive.

In the merger, each share of IBKC common stock issued and outstanding immediately prior to the effective time (other than certain shares held by First Horizon or IBKC) will be converted into 4.584 shares of First Horizon common stock. This exchange ratio is fixed and will not be adjusted for changes in the market price of either First Horizon common stock or IBKC common stock. Changes in the price of First Horizon common stock between now and the time of the merger will affect the value that holders of IBKC common stock will receive in the merger. Neither First Horizon nor IBKC is permitted to terminate the merger agreement as a result of any increase or decrease in the market price of First Horizon common stock or IBKC common stock.

Stock price changes may result from a variety of factors, including general market and economic conditions, changes in IBKC’s and First Horizon’s businesses, operations and prospects, the recent outbreak of the novel strain of coronavirus, COVID-19 and regulatory considerations, many of which factors are beyond IBKC’s and First Horizon’s control. Therefore, at the time of the First Horizon special meeting and the IBKC special meeting, holders of First Horizon common stock and holders of IBKC common stock will not know the market value of the consideration that IBKC shareholders will receive at the effective time. You should obtain current market quotations for shares of First Horizon common stock and for shares of IBKC common stock.

The market price of First Horizon common stock after the merger may be affected by factors different from those affecting the shares of IBKC common stock or First Horizon common stock currently.

In the merger, holders of IBKC common stock will become holders of First Horizon common stock. First Horizon’s business differs from that of IBKC. Accordingly, the results of operations of the combined company and the market price of First Horizon common stock after the completion of the merger may be affected by factors different from those currently affecting the independent results of operations of each of First Horizon and IBKC. For a discussion of the businesses of First Horizon and IBKC and of certain factors to consider in connection with those businesses, see the documents incorporated by reference in this joint proxy statement/prospectus and referred to under “Where You Can Find More Information” beginning on page 218.

The fairness opinions delivered by Morgan Stanley and KBW and Goldman Sachs, respectively, to First Horizon’s and IBKC’s respective boards of directors prior to the entry into the merger agreement will not reflect changes in circumstances that may have occurred since the dates of the opinions.

The respective boards of directors of First Horizon and IBKC have not obtained updated fairness opinions either as of the date of this joint proxy statement/prospectus or as of any other date subsequent to the dates of such opinions from Morgan Stanley, which is First Horizon’s financial advisor, or from KBW or Goldman Sachs, each of which is IBKC’s financial advisor. Changes in the operations and prospects of First Horizon or IBKC, general market and economic conditions and other factors which may be beyond the control of First Horizon and IBKC, may have altered the value of First Horizon or IBKC or the prices of shares of First Horizon common stock and shares of IBKC common stock as of the date of this joint proxy statement/prospectus, or may alter such

41

values and prices by the time the merger is completed. The opinions do not speak as of any date other than the dates of those opinions.

Combining First Horizon and IBKC may be more difficult, costly or time consuming than expected and First Horizon and IBKC may fail to realize the anticipated benefits of the merger.

The success of the merger will depend, in part, on the ability to realize the anticipated cost savings from combining the businesses of First Horizon and IBKC. To realize the anticipated benefits and cost savings from the merger, which are expected to be approximately $170 million in annual pre-tax cost savings (primarily resulting from redundancies in areas such as general overhead, bank branches, operations and computer services), First Horizon and IBKC must integrate and combine their businesses in a manner that permits those cost savings to be realized, without adversely affecting current revenues and future growth. If First Horizon and IBKC are not able to successfully achieve these objectives, the anticipated benefits of the merger may not be realized fully or at all or may take longer to realize than expected. In addition, the actual cost savings of the merger could be less than anticipated, and integration may result in additional and unforeseen expenses. For more information, see “Unaudited Pro Forma Condensed Combined Financial Statements—Note 5—Estimated Cost Savings and Merger Integration Costs” beginning on page 170.

An inability to realize the full extent of the anticipated benefits of the merger and the other transactions contemplated by the merger agreement, as well as any delays encountered in the integration process, could have an adverse effect upon the revenues, levels of expenses and operating results of the combined company, which may adversely affect the value of the common stock of the combined company after the completion of the merger.

First Horizon and IBKC have operated and, until the completion of the merger, must continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing businesses or inconsistencies in standards, controls, procedures and policies that adversely affect the companies’ ability to maintain relationships with clients, customers, depositors and employees or to achieve the anticipated benefits and cost savings of the merger. Integration efforts between the two companies may also divert management attention and resources. These integration matters could have an adverse effect on each of First Horizon and IBKC during this transition period and for an undetermined period after completion of the merger on the combined company.

Furthermore, the board of directors and executive leadership of the combined company will consist of former directors and executive officers from each of First Horizon and IBKC. Combining the boards of directors and management teams of each company into a single board and a single management team could require the reconciliation of differing priorities and philosophies.

The combined company may be unable to retain First Horizon and/or IBKC personnel successfully after the merger is completed.

The success of the merger will depend in part on the combined company’s ability to retain the talents and dedication of key employees currently employed by First Horizon and IBKC. It is possible that these employees may decide not to remain with First Horizon or IBKC, as applicable, while the merger is pending or with the combined company after the merger is consummated. If First Horizon and IBKC are unable to retain key employees, including management, who are critical to the successful integration and future operations of the companies, First Horizon and IBKC could face disruptions in their operations, loss of existing customers, loss of key information, expertise or know-how and unanticipated additional recruitment costs. In addition, if key employees terminate their employment, the combined company’s business activities may be adversely affected and management’s attention may be diverted from successfully integrating First Horizon and IBKC to hiring suitable replacements, all of which may cause the combined company’s business to suffer. In addition, First Horizon and IBKC may not be able to locate or retain suitable replacements for any key employees who leave either company. For more information, see “Governance of the Combined

42

Company After the Merger—Chairman of the Board and Chief Executive Officer” and “Governance of the Combined Company After the Merger—Management Team” each beginning on pages 130 and 131.

Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated or that could have an adverse effect on the combined company following the merger.

Before the merger and the bank merger may be completed, various approvals, consents and non-objections must be obtained from the Federal Reserve Board and various other bank regulatory, antitrust, insurance and other authorities in the United States. In determining whether to grant these approvals, such regulatory authorities consider a variety of factors, including the regulatory standing of each party and the factors described under “The Merger—Regulatory Approvals” beginning on page 132. These approvals could be delayed or not obtained at all, including due to: an adverse development in either party’s regulatory standing or in any other factors considered by regulators when granting such approvals; governmental, political or community group inquiries, investigations or opposition; or changes in legislation or the political environment generally. The Federal Reserve Board has stated that if material weaknesses are identified by examiners before a banking organization applies to engage in expansionary activity, the Federal Reserve Board will expect the banking organization to resolve all such weaknesses before applying for such expansionary activity. The Federal Reserve Board has also stated that if issues arise during the processing of an application for expansionary activity, it will expect the applicant banking organization to withdraw its application pending resolution of any supervisory concerns.

The approvals that are granted may impose terms and conditions, limitations, obligations or costs, or place restrictions on the conduct of the combined company’s business or require changes to the terms of the transactions contemplated by the merger agreement. There can be no assurance that regulators will not impose any such conditions, limitations, obligations or restrictions and that such conditions, limitations, obligations or restrictions will not have the effect of delaying the completion of any of the transactions contemplated by the merger agreement, imposing additional material costs on or materially limiting the revenues of the combined company following the merger or otherwise reduce the anticipated benefits of the merger if the merger were consummated successfully within the expected timeframe. In addition, there can be no assurance that any such conditions, terms, obligations or restrictions will not result in the delay or abandonment of the merger. Additionally, the completion of the merger is conditioned on the absence of certain orders, injunctions or decrees by any court or regulatory agency of competent jurisdiction that would prohibit or make illegal the completion of any of the transactions contemplated by the merger agreement.

In addition, despite the parties’ commitments to use their reasonable best efforts to comply with conditions imposed by regulators, under the terms of the merger agreement, neither First Horizon nor IBKC will be required, and neither party will be permitted without the prior written consent of the other party, to take actions or agree to conditions that would reasonably be expected to have a material adverse effect on the combined company and its subsidiaries, taken as a whole, after giving effect to the merger. See “The Merger—Regulatory Approvals” beginning on page 132.

The unaudited pro forma condensed combined financial information included in this joint proxy statement/prospectus is preliminary and the actual financial condition and results of operations of the combined company after the merger may differ materially.

The unaudited pro forma condensed combined financial information in this joint proxy statement/prospectus is presented for illustrative purposes only and are not necessarily indicative of what the combined company’s actual financial condition or results of operations would have been had the merger been completed on the dates indicated. The unaudited pro forma condensed combined financial information reflects adjustments, which are based upon preliminary estimates, to record the IBKC identifiable assets acquired and liabilities assumed at fair value and the resulting goodwill recognized. The purchase price allocation reflected in this document is preliminary, and

43

final allocation of the purchase price will be based upon the actual purchase price and the fair value of the assets and liabilities of IBKC as of the date of the completion of the merger. Accordingly, the final acquisition accounting adjustments may differ materially from the pro forma adjustments reflected in this document. For more information, see “Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page 163.

Certain of First Horizon’s and IBKC’s directors and executive officers may have interests in the merger that may differ from the interests of holders of First Horizon common stock and holders of IBKC common stock.

Holders of First Horizon common stock and holders of IBKC common stock should be aware that some of First Horizon’s and IBKC’s directors and executive officers may have interests in the merger and have arrangements that are different from, or in addition to, those of holders of First Horizon common stock and holders of IBKC common stock. These interests and arrangements may create potential conflicts of interest. The First Horizon and IBKC boards of directors were aware of these respective interests and considered these interests, among other matters, when making their decisions to approve the merger agreement, and in recommending that holders of common stock vote to approve the merger agreement. For a more complete description of these interests, please see “The Merger—Interests of Certain First Horizon Directors and Executive Officers in the Merger” beginning on page 113 and “The Merger—Interests of Certain IBKC Directors and Executive Officers in the Merger” beginning on page 119.

The merger agreement may be terminated in accordance with its terms and the merger may not be completed.

The merger agreement is subject to a number of conditions which must be fulfilled in order to complete the merger. Those conditions include: (i) the approval of the First Horizon merger proposal and the First Horizon charter amendment proposal by the requisite vote of the First Horizon shareholders; (ii) the approval of the IBKC merger proposal by the requisite vote of the IBKC shareholders; (iii) authorization for listing on the NYSE of the shares of First Horizon common stock and rollover First Horizon preferred stock (or depositary shares in respect thereof) to be issued in the merger; (iv) the receipt of all required regulatory approvals which are necessary to close the merger and the bank merger and the expiration of all statutory waiting periods without the imposition of any materially burdensome regulatory condition; (v) the effectiveness of the registration statement on Form S-4, of which this joint proxy statement/prospectus is a part, and the absence of a stop order or proceeding initiated or threatened by the SEC for that purpose; (vi) the absence of any order, injunction, decree or other legal restraint preventing the completion of the merger or any of the other transactions contemplated by the merger agreement or making the completion of the merger illegal; (vii) subject to certain exceptions, the accuracy of the representations and warranties of each party, generally subject to a material adverse effect qualification; (viii) the prior performance in all material respects by each party of the obligations required to be performed by it at or prior to the closing date; and (ix) receipt by each party of an opinion from its counsel to the effect that the merger will qualify as a reorganization within the meaning of Section 368(a) of the Code.

These conditions to the closing may not be fulfilled in a timely manner or at all, and, accordingly, the merger may not be completed. In addition, the parties can mutually decide to terminate the merger agreement at any time, before or after shareholder approval, or First Horizon or IBKC may elect to terminate the merger agreement in certain other circumstances. See “The Merger Agreement—Termination of the Merger Agreement” beginning on page 155.

Failure to complete the merger could negatively impact First Horizon or IBKC.

If the merger agreement is not completed for any reason, including as a result of First Horizon shareholders failing to approve either the First Horizon merger proposal or the First Horizon charter

44

amendment or IBKC shareholders failing to approve the IBKC merger proposal, there may be various adverse consequences and First Horizon and/or IBKC may experience negative reactions from the financial markets and from their respective customers and employees. For example, First Horizon’s or IBKC’s businesses may have been impacted adversely by the failure to pursue other beneficial opportunities due to the focus of management on the merger, without realizing any of the anticipated benefits of completing the merger. Additionally, if the merger agreement is terminated, the market price of First Horizon common stock or IBKC common stock could decline to the extent that current market prices reflect a market assumption that the merger will be beneficial and will be completed. First Horizon and/or IBKC also could be subject to litigation related to any failure to complete the merger or to proceedings commenced against First Horizon or IBKC to perform their respective obligations under the merger agreement. If the merger agreement is terminated under certain circumstances, either First Horizon or IBKC may be required to pay a termination fee of $156 million to the other party.

Additionally, each of First Horizon and IBKC has incurred and will incur substantial expenses in connection with the negotiation and completion of the transactions contemplated by the merger agreement, as well as the costs and expenses of preparing, filing, printing and mailing this joint proxy statement/prospectus, and all filing and other fees paid in connection with the merger. If the merger is not completed, First Horizon and IBKC would have to pay these expenses without realizing the expected benefits of the merger.

First Horizon and IBKC will be subject to business uncertainties and contractual restrictions while the merger is pending.

Uncertainty about the effect of the merger on employees and customers may have an adverse effect on First Horizon or IBKC. These uncertainties may impair First Horizon’s or IBKC’s ability to attract, retain and motivate key personnel until the merger is completed, and could cause customers and others that deal with First Horizon or IBKC to seek to change existing business relationships with First Horizon or IBKC. In addition, subject to certain exceptions, First Horizon and IBKC have agreed to operate their respective businesses in the ordinary course prior to the closing, and each party is restricted from making certain acquisitions and taking other specified actions without the consent of the other party until the merger is completed. These restrictions may prevent First Horizon and/or IBKC from pursuing attractive business opportunities that may arise prior to the completion of the merger. See “The Merger Agreement—Covenants and Agreements” beginning on page 147 for a description of the restrictive covenants applicable to First Horizon and IBKC.

The merger agreement contains provisions that could discourage a potential competing acquirer that might be willing to pay more to acquire or merge with either First Horizon or IBKC.

The merger agreement contains provisions that restrict each of First Horizon’s and IBKC’s ability to, among other things, initiate, solicit, knowingly encourage or knowingly facilitate, inquiries or proposals with respect to, or, subject to certain exceptions generally related to the exercise of fiduciary duties by each respective board of directors, engage in any negotiations concerning, or provide any confidential or nonpublic information or data relating to, any alternative acquisition proposals. These provisions, which include a $156 million termination fee payable under certain circumstances, might discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of First Horizon or IBKC from considering or proposing that acquisition even if, in the case of a potential acquisition of IBKC, it were prepared to pay consideration with a higher per share price to IBKC shareholders than what is contemplated in the merger, or might result in a potential competing acquirer proposing to pay a lower per share price to acquire First Horizon or IBKC than it might otherwise have proposed to pay. For more information, see “The Merger Agreement—Agreement Not to Solicit Other Offers; Termination of the Merger Agreement; Effect of Termination; Termination Fee” and “The Merger Agreement—Shareholder Meetings and Recommendation of First Horizon’s and IBKC’s Boards of Directors” beginning on pages 153 and 152 respectively.

45

The shares of First Horizon common stock to be received by holders of IBKC common stock as a result of the merger will have different rights from the shares of IBKC common stock.

In the merger, holders of IBKC common stock will become holders of First Horizon common stock and their rights as shareholders will be governed by Tennessee law and the governing documents of the combined company. The rights associated with First Horizon common stock are different from the rights associated with IBKC common stock. See “Comparison of Shareholders’ Rights” beginning on page 200 for a discussion of the different rights associated with First Horizon common stock.

The rights of holders of First Horizon common stock and of holders of rollover First Horizon depositary shares to pursue claims against First Horizon or the depositary, as applicable, are limited by First Horizon’s bylaws and by the terms of the deposit agreements.

First Horizon’s bylaws, which will govern the combined company following completion of the merger, provide that, unless First Horizon consents in writing to an alternative forum, a state or federal court located within Shelby County in the State of Tennessee will be the sole and exclusive forum for (i) any derivative action or proceeding brought in the right of First Horizon, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of First Horizon to First Horizon or its shareholders, (iii) any action asserting a claim against First Horizon or any director, officer or other employee of First Horizon arising pursuant to any provision of the TBCA, of First Horizon’s charter or bylaws or (iv) any action asserting a claim against First Horizon or any director, officer or other employee of First Horizon that is governed by the internal affairs doctrine. In addition, the deposit agreements between IBKC and the depositary, which will be assumed by First Horizon at closing and will govern the rights of the rollover First Horizon depositary shares following completion of the merger, provide that any action or proceeding arising out of or relating in any way to the applicable deposit agreement may only be brought in a state court located in the State of New York or in the United States District Court for the Southern District of New York.

The foregoing exclusive forum clauses may have the effect of discouraging lawsuits against First Horizon or its directors, officers or other employees, or against the depositary, as applicable. Exclusive forum clauses may also lead to increased costs to bring a claim, or may limit the ability of holders of First Horizon common stock or holders of rollover First Horizon depositary shares to bring a claim in a judicial forum they find favorable.

To the fullest extent permitted by law, the exclusive forum clauses in First Horizon’s bylaws and in the deposit agreements will apply, respectively, to any actions or proceedings described in the first paragraph of this risk factor that arise or purport to arise under the federal securities laws, including the Securities Act and the Exchange Act. However, holders of First Horizon common stock and holders of rollover First Horizon depositary shares will not be deemed to have waived First Horizon’s compliance with the federal securities laws and the rules and regulations thereunder. To the extent these exclusive forum provisions restrict the courts in which holders of First Horizon common stock or holders of rollover First Horizon depositary shares may bring claims arising under the federal securities laws, there is uncertainty as to whether a court would enforce such provisions.

First Horizon and IBKC will incur transaction and integration costs in connection with the merger.

First Horizon and IBKC have incurred and expect to incur significant, non-recurring costs in connection with negotiating the merger agreement and closing the merger. In addition, the combined company will incur integration costs following the completion of the merger as First Horizon and IBKC integrate their businesses, including facilities and systems consolidation costs and employment-related costs. Anticipated future merger and integration-related pre-tax costs are currently estimated to be $440 million. For more information, see “Unaudited Pro Forma Condensed Combined Financial Statements—Note 5—Estimated Cost Savings and Merger Integration Costs” beginning on page 170.

46

There can be no assurances that the expected benefits and efficiencies related to the integration of the businesses will be realized to offset these transaction and integration costs over time. First Horizon and IBKC may also incur additional costs to maintain employee morale and to retain key employees. First Horizon and IBKC will also incur significant legal, financial advisory, accounting, banking and consulting fees, fees relating to regulatory filings and notices, SEC filing fees, printing and mailing fees and other costs associated with the merger. Some of these costs are payable regardless of whether the merger is completed. See “The Merger Agreement—Expenses and Fees” beginning on page 157.

In connection with the merger, First Horizon will assume IBKC’s outstanding debt obligations and preferred stock, and the combined company’s level of indebtedness following the completion of the merger could adversely affect the combined company’s ability to raise additional capital and to meet its obligations under its existing indebtedness.

In connection with the merger, First Horizon will assume IBKC’s outstanding indebtedness and IBKC’s obligations related to its outstanding preferred stock. As of December 31, 2019, IBKC’s outstanding consolidated indebtedness consisted of $1,343,687,000 in long-term debt obligations, consisting of $1,188,584,000 in Federal Home Loan Bank advances, $34,993,000 in notes payable, and $120,110,000 in trust preferred securities. Of such long-term debt obligations, $582,371,000 matures in 2020, $175,225,000 matures in 2021 and the balance matures in 2022 and thereafter. First Horizon’s existing debt, together with any future incurrence of additional indebtedness, and the assumption of IBKC’s outstanding preferred stock, could have important consequences for the combined company’s creditors and the combined company’s shareholders. For example, it could:

| • |  | limit the combined company’s ability to obtain additional financing for working capital, capital expenditures, debt service requirements, acquisitions and general corporate or other purposes;
| • |  | restrict the combined company from making strategic acquisitions or cause the combined company to make non-strategic divestitures;
| • |  | restrict the combined company from paying dividends to its shareholders;
| • |  | increase the combined company’s vulnerability to general economic and industry conditions; and
| • |  | require a substantial portion of cash flow from operations to be dedicated to the payment of principal and interest on the combined company’s indebtedness and dividends on the preferred stock, thereby reducing the combined company’s ability to use cash flows to fund its operations, capital expenditures and future business opportunities.

Following completion of the merger, holders of First Horizon common stock will be subject to the prior dividend and liquidation rights of the holders of the First Horizon preferred stock and the rollover First Horizon preferred stock that First Horizon will issue upon completion of the merger. Holders of shares of IBKC preferred stock, which will be converted into rollover First Horizon preferred stock, as well as holders of shares of First Horizon preferred stock and any shares of preferred stock that First Horizon may issue in the future, would receive, upon the combined company’s voluntary or involuntary liquidation, dissolution or winding up, before any payment is made to holders of First Horizon common stock, their liquidation preferences as well as any accrued and unpaid distributions. These payments would reduce the remaining amount of the combined company’s assets, if any, available for distribution to holders of its common stock.

General market conditions and unpredictable factors, including conditions and factors different from those affecting IBKC preferred stock and IBKC depositary shares currently, could adversely affect market prices for rollover First Horizon preferred stock and rollover First Horizon depositary shares once the rollover First Horizon preferred stock is issued.

There can be no assurance about the market prices for the rollover First Horizon preferred stock that will be issued upon completion of the merger or the rollover First Horizon depositary shares.

47

Several factors, many of which are beyond the control of First Horizon, could influence the market prices of the rollover First Horizon preferred stock and the rollover First Horizon depositary shares, including:

| • |  | whether the combined company declares or fails to declare dividends on the rollover First Horizon preferred stock from time to time;
| • |  | real or anticipated changes in the credit ratings assigned to the rollover First Horizon preferred stock and the rollover First Horizon depositary shares or other First Horizon securities;
| • |  | the combined company’s creditworthiness;
| • |  | interest rates;
| • |  | developments in the securities, credit and housing markets, and developments with respect to financial institutions generally;
| • |  | the market for similar securities; and
| • |  | economic, corporate, securities market, geopolitical, public health (including the impact of the coronavirus (COVID-19)), regulatory or judicial events that affect the combined company, the banking industry or the financial markets generally.

Shares of rollover First Horizon preferred stock will be equity interests and will not constitute indebtedness. As such, rollover First Horizon preferred stock and rollover First Horizon depositary shares will rank junior to all indebtedness of, and other non-equity claims on, the combined company with respect to assets available to satisfy claims. The market prices for the rollover First Horizon preferred stock and rollover First Horizon depositary shares following the merger may be affected by factors different from those currently affecting the IBKC preferred stock and IBKC depositary shares.

The recent global coronavirus outbreak could harm business and results of operations for each of First Horizon and IBKC and the combined company following the completion of the merger

In December 2019, a coronavirus (COVID-19) was reported in China, and, in January 2020, the World Health Organization declared it a Public Health Emergency of International Concern. The coronavirus has since spread to additional countries including the United States. Given the ongoing and dynamic nature of the circumstances, it is difficult to predict the impact of the coronavirus outbreak on businesses of First Horizon, IBKC and the combined company, and there is no guarantee that efforts by First Horizon, IBKC and the combined company to address the adverse impacts of the coronavirus will be effective. The extent of such impact will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity of the coronavirus and actions taken to contain the coronavirus or its impact, among others. If First Horizon or IBKC are unable to recover from a business disruption on a timely basis, the merger and the combined company's business and financial conditions and results of operations following the completion of the merger would be adversely affected. The merger and efforts to integrate the businesses of First Horizon and IBKC may also be delayed and adversely affected by the coronavirus outbreak, and become more costly. Each of First Horizon, IBKC and the combined company may also incur additional costs to remedy damages caused by such disruptions, which could adversely affect its financial condition and results of operations.

Holders of First Horizon and IBKC common stock will have a reduced ownership and voting interest in the combined company after the merger and will exercise less influence over management.

Holders of First Horizon and IBKC common stock currently have the right to vote in the election of the board of directors and on other matters affecting First Horizon and IBKC, respectively. When the merger is completed, each IBKC shareholder will become a shareholder of First Horizon, and each holder of First Horizon common stock and each holder of IBKC common stock will become a

48

holder of common stock of the combined company, with a percentage ownership of the combined company that is smaller than the shareholder’s percentage ownership of either First Horizon or IBKC individually, as applicable, prior to the consummation of the merger. Based on the number of shares of First Horizon and IBKC common stock outstanding as of the close of business on the respective record date, and based on the number of shares of First Horizon common stock expected to be issued in the merger, the former holders of IBKC common stock, as a group, are estimated to own approximately forty-four percent (44%) of the outstanding shares of the combined company immediately after the merger and current holders of First Horizon common stock as a group are estimated to own approximately fifty-six percent (56%) of the outstanding shares of the combined company immediately after the merger. Because of this, holders of IBKC common stock may have less influence on the management and policies of the combined company than they now have on the management and policies of IBKC, and holders of First Horizon common stock may have less influence on the management and policies of the combined company than they now have on the management and policies of First Horizon.

Holders of First Horizon common stock and holders of IBKC common stock will not have dissenters’ rights or appraisal rights in the merger.

Appraisal rights (also known as dissenters’ rights) are statutory rights that, if applicable under law, enable shareholders to dissent from an extraordinary transaction, such as a merger, and to demand that the corporation pay the fair value for their shares as determined by a court in a judicial proceeding instead of receiving the consideration offered to shareholders in connection with the extraordinary transaction.

Under Section 48-23-102 of the TBCA, the holders of First Horizon common stock will not be entitled to dissenters’ rights in connection with the merger with respect to shares of any class or series that remain outstanding after completion of the merger. If the merger is completed, holders of First Horizon common stock will not receive any consideration, and their shares of First Horizon common stock will remain outstanding and will constitute shares of the combined company. Accordingly, holders of First Horizon common stock are not entitled to any dissenters’ rights in connection with the merger.

Under Part 13 of the LBCA, the holders of IBKC common stock will not be entitled to appraisal rights in connection with the merger if, on the record date for the IBKC special meeting, IBKC’s shares are traded in an organized market that has at least two thousand (2,000) shareholders and a market value of at least $20 million. IBKC common stock is currently listed on the NASDAQ, a national securities exchange, and is expected to continue to be so listed on the record date for the IBKC special meeting. Accordingly, the holders of IBKC common stock are not entitled to any appraisal rights in connection with the merger.

Holders of record of IBKC preferred stock are entitled to exercise appraisal rights in connection with the merger, provided the proper procedures of Part 13 of the LBCA are followed. DTC, as nominee for the depository, is the holder of record of the shares of IBKC preferred stock as of the date of this joint proxy statement/prospectus.

The IBKC depositary shares are not a class or series of shares issued by IBKC and thus appraisal rights under Part 13 of the LBCA do not independently apply to the depositary shares. Accordingly, to exercise or to direct the depository to exercise appraisal rights with respect to the IBKC preferred stock, holders of depositary shares will be required to follow the procedures provided by the depository with respect thereto and in accordance with requirements of Louisiana law.

Shareholder litigation could prevent or delay the completion of the merger or otherwise negatively impact the business and operations of First Horizon and IBKC.

Shareholders of First Horizon and/or IBKC may file lawsuits against First Horizon, IBKC and/or the directors and officers of either company in connection with the merger. One of the conditions to the closing is that no order, injunction or decree issued by any court or governmental entity of competent jurisdiction or other legal restraint preventing the consummation of the merger or any of the other transactions contemplated by the merger agreement be in effect. If any plaintiff were

49

successful in obtaining an injunction prohibiting First Horizon or IBKC defendants from completing the merger pursuant to the merger agreement, then such injunction may delay or prevent the effectiveness of the merger and could result in significant costs to First Horizon and/or IBKC, including any cost associated with the indemnification of directors and officers of each company. If a lawsuit is filed, First Horizon and IBKC may incur costs in connection with the defense or settlement of any shareholder lawsuits filed in connection with the merger. Such litigation could have an adverse effect on the financial condition and results of operations of First Horizon and IBKC and could prevent or delay the completion of the merger.

Litigation relating to the merger could delay and/or enjoin the merger.

Following the public announcement of the merger agreement, purported stockholders of IBKC filed a putative class action lawsuit and three individual lawsuits against IBKC, the members of the IBKC board of directors, and in the case of the putative class action, against First Horizon. Two of the individual lawsuits were filed in the United States District Court for the Eastern District of New York (Hertz v. IBERIABANK et al., No. 1:20-cv-00267 (filed Jan. 16, 2020); Cooksey v. IBERIABANK et al., No. 1:20-cv-00431 (filed Jan. 26, 2020)) and the third was filed in the United States District Court for the Southern District of New York, (Wang v. IBERIABANK, et al., No. 1:20-cv-00105 (filed on Jan. 6, 2020)). The putative class action was filed in the United States District Court for the District of Delaware (Parshall v. IBERIABANK et al., No. 1:20-cv-00027 (Jan. 8, 2020)). The complaints contain similar allegations contending, among other things, that the registration statement on Form S-4 misstated or failed to disclose certain allegedly material information in violation of federal securities laws. The complaints seek injunctive relief enjoining the merger, attorneys and experts’ fees, and other remedies. Additional lawsuits against First Horizon, IBKC, and/or the directors and officers of either company in connection with the merger may be filed. The outcome of the pending and any additional future litigation is uncertain. If any case is not resolved, the lawsuit(s) could prevent or delay completion of the merger and result in substantial costs to First Horizon and IBKC, including any costs associated with the indemnification of directors and officers. One of the conditions to the closing of the merger is that no order, injunction or decree issued by any court or agency of competent jurisdiction or other legal restraint or prohibition preventing the consummation of the merger or the bank merger shall be in effect. As such, if plaintiffs are successful in obtaining an injunction prohibiting the completion of the merger or the bank merger on the agreed-upon terms, then such injunction may prevent the merger from being completed, or from being completed within the expected timeframe. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger is completed may adversely affect the combined company’s business, financial condition, results of operations and cash flows. See “The Merger—Litigation Relating to the Merger” on page 139.

Risks Relating to First Horizon’s Business

You should read and consider risk factors specific to First Horizon’s business that will also affect the combined company after the merger. These risks are described in the sections entitled “Risk Factors” in First Horizon’s Annual Report on Form 10-K for the year ended December 31, 2019 and in other documents incorporated by reference into this joint proxy statement/prospectus.

This joint proxy statement/prospectus is accompanied by a notice of the First Horizon special meeting, and a form of proxy card that the First Horizon board of directors is soliciting for use by holders of First Horizon common stock at the special meeting and at any adjournments or postponements of the special meeting.

The First Horizon special meeting will be held on [ ] at [ ], at [ ] local time.

| • |  | the First Horizon merger proposal;
| • |  | the First Horizon charter amendment proposal;
| • |  | the First Horizon compensation proposal; and

Recommendation of First Horizon’s Board of Directors

The First Horizon board of directors recommends that you vote “FOR” the First Horizon merger proposal, “FOR” the First Horizon charter amendment proposal, “FOR” the First Horizon compensation proposal and “FOR” the First Horizon adjournment proposal.

Record Date and Quorum

The First Horizon board of directors has fixed the close of business on February 24, 2020 as the record date for determination of holders of First Horizon common stock entitled to notice of and to vote at the First Horizon special meeting. As of the record date, there were [ ] shares of First Horizon common stock outstanding.

Holders of a majority of the shares of First Horizon common stock outstanding on the record date must be present, either in person or by proxy, to constitute a quorum at the First Horizon special meeting. If you fail to submit a proxy or to vote in person at the First Horizon special meeting, your shares of First Horizon common stock will not be counted towards a quorum. Abstentions are considered present for purposes of establishing a quorum.

At the First Horizon special meeting, each share of First Horizon common stock is entitled to one (1) vote on all matters properly submitted to holders of First Horizon common stock.

As of February 24, 2020, First Horizon directors and executive officers and their affiliates owned and were entitled to vote approximately [ ] shares of First Horizon common stock, representing less than [ ] percent ([ ]%) of the outstanding shares of First Horizon common stock. We currently expect that First Horizon’s directors and executive officers will vote their shares in favor of the merger and the First Horizon charter amendment proposal, although none of them has entered into any agreements obligating them to do so.

51

Vote Required; Treatment of Abstentions and Failure to Vote

First Horizon merger proposal:

| • |  | Vote required: Approval of the First Horizon merger proposal requires the affirmative vote of a majority of the votes entitled to be cast on First Horizon merger proposal by the holders of First Horizon common stock. Approval of the First Horizon merger proposal is a condition to the completion of the merger.
| • |  | Effect of abstentions and broker non-votes: If you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the First Horizon special meeting or fail to instruct your bank, broker or other nominee how to vote with respect to the First Horizon merger proposal, it will have the same effect as a vote “AGAINST” the First Horizon merger proposal.

First Horizon charter amendment proposal:

| • |  | Vote required: Approval of the First Horizon charter amendment proposal requires the affirmative vote of the holders of at least a majority of the votes cast at the First Horizon special meeting.

First Horizon compensation proposal:

Approval of the First Horizon compensation proposal is not a condition to the completion of the merger.

Holders of First Horizon preferred stock are also entitled to notice of the special meeting, but holders of First Horizon preferred stock and holders of depositary shares representing interest in

52

shares of First Horizon preferred stock are not entitled to and are not requested to vote at the First Horizon special meeting.

Attending the Special Meeting

All holders of First Horizon common stock, including holders of record and shareholders who hold their shares of First Horizon common stock through banks, brokers or other nominees are invited to attend the First Horizon special meeting. Shareholders of record can vote in person at the First Horizon special meeting. If you are not a shareholder of record, you must obtain a proxy executed in your favor from the record holder of your shares, such as a broker, bank or other nominee, to be able to vote in person at the First Horizon special meeting. If you plan to attend the First Horizon special meeting, you must hold your shares in your own name or have a letter from the record holder of your shares confirming your ownership. In addition, you must bring a form of personal photo identification with you in order to be admitted. First Horizon reserves the right to refuse admittance to anyone without proper proof of share ownership and without proper photo identification. The use of cameras, sound recording equipment, communications devices or any similar equipment during the First Horizon special meeting is prohibited without First Horizon’s express written consent.

Proxies

A holder of First Horizon common stock may vote by proxy or in person at the First Horizon special meeting. If you hold your shares of First Horizon common stock in your name as a holder of record, to submit a proxy, you, as a holder of First Horizon common stock, may use one of the following methods:

| • |  | By telephone: by calling the toll-free number indicated on the accompanying proxy card and following the recorded instructions.
| • |  | Through the Internet: by visiting the website indicated on the accompanying proxy card and following the instructions.
| • |  | By completing and returning the accompanying proxy card in the enclosed postage-paid envelope. The envelope requires no additional postage if mailed in the United States.

First Horizon requests that holders of First Horizon common stock vote by telephone, over the Internet or by completing and signing the accompanying proxy card and returning it to First Horizon as soon as possible in the enclosed postage-paid envelope. When the accompanying proxy card is returned properly executed, the shares of First Horizon common stock represented by it will be voted at the First Horizon special meeting in accordance with the instructions contained on the proxy card. If you make no specification on your proxy card as to how you want your shares voted before signing and returning it, your proxy will be voted “FOR” the First Horizon merger proposal, “FOR” the First Horizon charter amendment proposal, “FOR” the First Horizon compensation proposal and “FOR” the First Horizon adjournment proposal.

If a holder’s shares are held in “street name” by a broker, bank or other nominee, the holder should check the voting form used by that firm to determine whether the holder may vote by telephone or the Internet.

Every vote is important. Accordingly, you should sign, date and return the enclosed proxy card, or vote via the Internet or by telephone, whether or not you plan to attend the First Horizon special meeting in person. Sending in your proxy card or voting by telephone or on the Internet will not prevent you from voting your shares personally at the meeting because you may revoke your proxy at any time before it is voted.

53

Shares Held in Street Name

If your shares are held in “street name” through a broker, bank or other nominee, you must instruct the broker, bank or other nominee on how to vote your shares. Your broker, bank or other nominee will vote your shares only if you provide specific instructions on how to vote by following the instructions provided to you by your broker, bank or other nominee.

You may not vote shares held in street name by returning a proxy card directly to First Horizon or by voting in person at the First Horizon special meeting unless you provide a “legal proxy” giving you the right to vote the shares, which you must obtain from your broker, bank or other nominee. If you choose to vote your shares in person at the First Horizon special meeting, please bring proof of identification.

Further, brokers, banks or other nominees who hold shares of First Horizon common stock on behalf of their customers may not give a proxy to First Horizon to vote those shares with respect to any of the proposals without specific instructions from their customers, as brokers, banks, and other nominees do not have discretionary voting power on the proposals that will be voted upon at the First Horizon special meeting.

Revocability of Proxies

If you are a holder of First Horizon common stock of record, you may revoke your proxy at any time before it is voted by:

| • |  | submitting a written notice of revocation to First Horizon’s corporate secretary;
| • |  | granting a subsequently dated proxy;
| • |  | voting by telephone or the Internet at a later time; or
| • |  | attending in person and voting at the First Horizon special meeting.

If you hold your shares of First Horizon common stock through a broker, bank or other nominee, you should contact your broker, bank or other nominee to change your vote.

Attendance at the First Horizon special meeting will not in and of itself constitute revocation of a proxy. A revocation or later-dated proxy received by First Horizon after the vote will not affect the vote. First Horizon’s corporate secretary’s mailing address is: Corporate Secretary, First Horizon National Corporation, 165 Madison Avenue, Memphis, Tennessee 38103. If the First Horizon special meeting is postponed or adjourned, it will not affect the ability of holders of First Horizon common stock of record as of the record date to exercise their voting rights or to revoke any previously-granted proxy using the methods described above.

Delivery of Proxy Materials

As permitted by applicable law, only one (1) copy of this joint proxy statement/prospectus is being delivered to holders of First Horizon common stock residing at the same address, unless such holders of First Horizon common stock have notified First Horizon of their desire to receive multiple copies of the joint proxy statement/prospectus.

FIRST HORIZON PROPOSALS

PROPOSAL 1: FIRST HORIZON MERGER PROPOSAL

First Horizon is asking holders of First Horizon common stock to approve the merger agreement and the transactions contemplated thereby. Holders of First Horizon common stock should read this joint proxy statement/prospectus carefully and in its entirety, including the annexes, for more detailed information concerning the merger agreement and the merger. A copy of the merger agreement is attached to this joint proxy statement/prospectus as Annex A.

After careful consideration, the First Horizon board of directors unanimously determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are advisable and in the best interests of First Horizon and its shareholders and unanimously approved and adopted the merger agreement, the merger and the other transactions contemplated by the merger agreement. See “The Merger—First Horizon’s Reasons for the Merger; Recommendation of First Horizon’s Board of Directors” beginning on page 73 in this joint proxy statement/prospectus for a more detailed discussion of the First Horizon board of directors’ recommendation.

The approval of the merger by holders of First Horizon common stock is a condition to the completion of the merger.

The First Horizon board of directors unanimously recommends a vote “FOR” the First Horizon merger proposal.

PROPOSAL 2: FIRST HORIZON CHARTER AMENDMENT PROPOSAL

In connection with the merger, First Horizon is asking the holders of First Horizon common stock to approve an amendment to the First Horizon charter to effect an increase in the number of authorized shares of First Horizon common stock from 400,000,000 to 700,000,000, to be effective only upon the completion of the merger. A copy of the proposed articles of amendment to First Horizon’s charter is attached to this joint proxy statement/prospectus as Annex F. Holders of First Horizon common stock should read the First Horizon charter amendment in its entirety.

The approval of the First Horizon charter amendment proposal by holders of First Horizon common stock is a condition to the completion of the merger.

The First Horizon board of directors unanimously recommends a vote “FOR” the First Horizon charter amendment proposal.

PROPOSAL 3: FIRST HORIZON COMPENSATION PROPOSAL

Pursuant to Section 14A of the Exchange Act and Rule 14a-21(c) thereunder, First Horizon is seeking a non-binding, advisory stockholder approval of the compensation of First Horizon’s named executive officers that is based on or otherwise relates to the merger as disclosed in the section entitled “The Merger—Interests of Certain First Horizon Directors and Executive Officers in the Merger—Quantification of Payments and Benefits to First Horizon’s Named Executive Officers—Golden Parachute Compensation” beginning on page 118. The proposal gives holders of First Horizon common stock the opportunity to express their views on the merger-related compensation of First Horizon’s named executive officers.

Accordingly, First Horizon is asking holders of First Horizon common stock to vote “FOR” the adoption of the following resolution, on a non-binding advisory basis:

“RESOLVED, that the compensation that will or may be paid or become payable to the First Horizon named executive officers, in connection with the merger, and the agreements or understandings pursuant to which such compensation will or may be paid or become payable, in each case as disclosed pursuant to Item 402(t) of Regulation S-K in “Interests of Certain First Horizon Directors and Executive Officers in the Merger—Quantification of Payments and Benefits

56

to First Horizon’s Named Executive Officers—Golden Parachute Compensation” are hereby APPROVED.”

The advisory vote on the First Horizon compensation proposal is a vote separate and apart from the votes on the First Horizon merger proposal, the First Horizon charter amendment proposal and the First Horizon adjournment proposal. Accordingly, if you are a holder of First Horizon common stock, you may vote to approve the First Horizon merger proposal, the First Horizon charter amendment proposal and/or the First Horizon adjournment proposal and vote not to approve the First Horizon compensation proposal, and vice versa. The approval of the First Horizon compensation proposal by holders of First Horizon common stock is not a condition to the completion of the merger. If the merger is completed, the merger-related compensation will be paid to First Horizon’s named executive officers to the extent payable in accordance with the terms of the compensation agreements and arrangements even if holders of First Horizon common stock fail to approve the advisory vote regarding merger-related compensation.

The First Horizon board of directors unanimously recommends a vote “FOR” the advisory First Horizon compensation proposal.

PROPOSAL 4: FIRST HORIZON ADJOURNMENT PROPOSAL

The First Horizon special meeting may be adjourned to another time or place, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the First Horizon special meeting to approve the First Horizon merger proposal and/or the First Horizon charter amendment or to ensure that any supplement or amendment to this joint proxy statement/prospectus is timely provided to holders of First Horizon common stock.

If, at the First Horizon special meeting, the number of shares of First Horizon common stock present or represented and voting in favor of the First Horizon merger proposal and/or the First Horizon charter amendment proposal is insufficient to approve the First Horizon merger proposal and/or the First Horizon charter amendment proposal, as the case may be, First Horizon intends to move to adjourn the First Horizon special meeting in order to enable the First Horizon board of directors to solicit additional proxies for approval of the First Horizon merger proposal and/or the First Horizon charter amendment proposal. In that event, First Horizon will ask holders of First Horizon common stock to vote upon the First Horizon adjournment proposal, but not the First Horizon merger proposal or the First Horizon charter amendment proposal.

In this proposal, First Horizon is asking holders of First Horizon common stock to authorize the holder of any proxy solicited by the First Horizon board of directors, on a discretionary basis, if a quorum is not present and (i) if there are not sufficient votes at the time of the First Horizon special meeting to approve the First Horizon merger proposal and/or the First Horizon charter amendment proposal or (ii) if necessary or appropriate to ensure that any supplement or amendment to this joint proxy statement/prospectus is timely provided to holders of First Horizon common stock, to vote in favor of adjourning the First Horizon special meeting to another time and place for the purpose of soliciting additional proxies, including the solicitation of proxies from holders of First Horizon common stock who have previously voted. Pursuant to First Horizon’s bylaws, whether or not a quorum is obtained at the First Horizon special meeting, the chairman of the First Horizon special meeting may adjourn the meeting without notice, except as provided by law and other than by announcement at the First Horizon special meeting, and may do so without a vote of holders of First Horizon common stock.

The approval of the First Horizon adjournment proposal by holders of First Horizon common stock is not a condition to the completion of the merger.

The First Horizon board of directors unanimously recommends a vote “FOR” the First Horizon adjournment proposal.

57

Record Date and Quorum

The IBKC board of directors has fixed the close of business on February 24, 2020 as the record date for determination of holders of IBKC common stock entitled to notice of and to vote at the IBKC special meeting. As of the record date, there were [ ] shares of IBKC common stock outstanding.

The presence at the IBKC special meeting, in person or by proxy, of the holders of a majority of the outstanding shares of IBKC common stock entitled to vote at the IBKC special meeting will constitute a quorum for purposes of taking actions on the IBKC merger proposal, the IBKC compensation proposal and the IBKC adjournment proposal. Abstentions will be included in determining the number of shares present at the IBKC special meeting for the purpose of determining the presence of a quorum.

At the IBKC special meeting, each share of IBKC common stock is entitled to one (1) vote on all matters properly submitted to holders of IBKC common stock.

As of February 24, 2020, IBKC directors and executive officers and their affiliates owned and were entitled to vote approximately [ ] shares of IBKC common stock, representing less than [ ] percent ([ ]%) of the outstanding shares of IBKC common stock. We currently expect that IBKC’s directors and executive officers will vote their shares in favor of the merger, although none of them has entered into any agreements obligating them to do so.

58

Vote Required; Treatment of Abstentions and Failure to Vote

IBKC merger proposal:

| • |  | Vote required: Approval of the IBKC merger proposal requires the affirmative vote of a majority of all votes entitled to be cast on the IBKC merger proposal by holders of IBKC common stock. Approval of the IBKC merger proposal is a condition to the completion of the merger.

IBKC compensation proposal:

| • |  | Vote required: Approval of the IBKC compensation proposal requires the affirmative vote of the holders of at least a majority of the votes cast by holders of IBKC common stock at the IBKC special meeting. Approval of the IBKC compensation proposal is not a condition to the completion of the merger.
| • |  | Effect of abstentions and broker non-votes: If you mark “ABSTAIN” on your proxy, fail to submit a proxy or vote in person at the IBKC special meeting or fail to instruct your bank, broker or other nominee how to vote with respect to the IBKC compensation proposal, you will not be deemed to have cast a vote with respect to the IBKC compensation proposal and it will have no effect on the IBKC compensation proposal.

Holders of IBKC preferred stock are also entitled to notice of the IBKC special meeting, but holders of IBKC preferred stock and holders of IBKC depositary shares are not entitled to and are not requested to vote at the IBKC special meeting.

Attending the Special Meeting

The proxy card is your admission ticket. When you arrive at the IBKC special meeting, you will be asked to present photo identification, such as a driver’s license. If you are a beneficial owner of IBKC common stock held by a broker, bank or other nominee, you will need proof of ownership to be admitted to the meeting. A recent brokerage statement or a letter from a bank or broker are examples of proof of ownership. If you want to vote your IBKC shares held in nominee name in person, you must get a “legal proxy” in your name from the broker, bank or other nominee that holds your shares.

59

Every vote is important. Accordingly, you should sign, date and return the enclosed proxy card, or vote via the Internet or by telephone, whether or not you plan to attend the IBKC special meeting in person. Sending in your proxy card or voting by telephone or on the Internet will not prevent you from voting your shares personally at the meeting because you may revoke your proxy at any time before it is voted.

Shares Held in Street Name

If your shares are held in “street name” through a broker, bank or other nominee, you must instruct the broker, bank or other nominee on how to vote your shares.

Further, brokers, banks or other nominees who hold shares on behalf of their customers may not give a proxy to IBKC to vote those shares with respect to any of the proposals without specific instructions from their customers, as brokers, banks, and other nominees do not have discretionary voting power on the proposals that will be voted upon at the IBKC special meeting.

Revocability of Proxies

If you are a holder of IBKC shares of record, you may revoke your proxy at any time before it is voted by:

IBKC PROPOSALS

PROPOSAL 1: IBKC MERGER PROPOSAL

IBKC is asking holders of IBKC common stock to approve the merger agreement and the transactions contemplated thereby. Holders of IBKC common stock should read this joint proxy statement/prospectus carefully and in its entirety, including the annexes, for more detailed information concerning the merger agreement and the merger. A copy of the merger agreement is attached to this joint proxy statement/prospectus as Annex A.

After careful consideration, the IBKC board of directors, by a unanimous vote of all directors, approved and adopted the merger agreement and declared the merger agreement and the transactions contemplated thereby, including the merger, to be advisable and in the best interest of IBKC and the shareholders of IBKC. See “The Merger—IBKC’s Reasons for the Merger; Recommendation of IBKC’s Board of Directors” beginning on page 76 for a more detailed discussion of the IBKC board of directors’ recommendation.

The approval of the IBKC merger proposal by holders of the IBKC common stock is a condition to the completion of the merger.

The IBKC board of directors recommends a vote “FOR” the IBKC merger proposal.

PROPOSAL 2: IBKC COMPENSATION PROPOSAL

Pursuant to Section 14A of the Exchange Act and Rule 14a-21(c) thereunder, IBKC is seeking a non-binding, advisory stockholder approval of the compensation of IBKC’s named executive officers that is based on or otherwise relates to the merger as disclosed in the section entitled “The Merger—Interests of Certain IBKC Directors and Executive Officers in the Merger—Quantification of Payments and Benefits to IBKC’s Named Executive Officers—Golden Parachute Compensation” beginning on page 127. The proposal gives holders of IBKC common stock the opportunity to express their views on the merger-related compensation of IBKC’s named executive officers.

Accordingly, IBKC is asking holders of IBKC common stock to vote “FOR” the adoption of the following resolution, on a non-binding advisory basis:

“RESOLVED, that the compensation that will or may be paid or become payable to the IBKC named executive officers, in connection with the merger, and the agreements or understandings pursuant to which such compensation will or may be paid or become payable, in each case as disclosed pursuant to Item 402(t) of Regulation S-K in “Interests of Certain IBKC Directors and Executive Officers in the Merger—Quantification of Payments and Benefits to IBKC’s Named Executive Officers—Golden Parachute Compensation,” are hereby APPROVED.”

The advisory vote on the IBKC compensation proposal is a vote separate and apart from the votes on the IBKC merger proposal and the IBKC adjournment proposal. Accordingly, if you are a holder of IBKC common stock, you may vote to approve the IBKC merger proposal and/or the IBKC adjournment proposal and vote not to approve the IBKC compensation proposal, and vice versa. The approval of the IBKC compensation proposal by holders of IBKC common stock is not a condition to the completion of the merger. If the merger is completed, the merger-related compensation will be paid to IBKC’s named executive officers to the extent payable in accordance with the terms of the compensation agreements and arrangements even if holders of IBKC common stock fail to approve the advisory vote regarding merger-related compensation.

The IBKC board of directors unanimously recommends a vote “FOR” the advisory IBKC compensation proposal.

62

PROPOSAL 3: IBKC ADJOURNMENT PROPOSAL

The IBKC special meeting may be adjourned to another time or place, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the IBKC special meeting to approve the IBKC merger proposal.

If, at the IBKC special meeting, the number of shares of IBKC common stock present or represented and voting in favor of the IBKC merger proposal is insufficient to approve the IBKC merger proposal, IBKC intends to move to adjourn the IBKC special meeting in order to enable the IBKC board of directors to solicit additional proxies for approval of the IBKC merger proposal. In that event, IBKC will ask holders of IBKC common stock to vote upon the IBKC adjournment proposal, but not the IBKC merger proposal or the IBKC compensation proposal.

In this proposal, IBKC is asking holders of IBKC common stock to authorize the holder of any proxy solicited by the IBKC board of directors on a discretionary basis (i) if there are not sufficient votes at the time of the IBKC special meeting to approve the IBKC merger proposal or (ii) if necessary or appropriate to ensure that any supplement or amendment to this joint proxy statement/prospectus is timely provided to holders of IBKC common stock, to vote in favor of adjourning the IBKC special meeting to another time and place for the purpose of soliciting additional proxies, including the solicitation of proxies from holders of IBKC common stock who have previously voted. Pursuant to IBKC’s bylaws, the IBKC special meeting may be adjourned without new notice being given unless a new record date is set for the adjourned meeting

The approval of the IBKC adjournment proposal by the holders of IBKC common stock is not a condition to the completion of the merger.

The IBKC board of directors recommends a vote “FOR” the IBKC adjournment proposal.

Terms of the Merger

Each of First Horizon’s and IBKC’s respective boards of directors has approved and adopted the merger agreement. The merger agreement provides that IBKC will merge with and into First Horizon, with First Horizon as the surviving entity in a merger of equals.

See “The Merger Agreement” beginning on page 141 for additional and more detailed information regarding the legal documents that govern the merger, including information about the conditions to the completion of the merger and the provisions for terminating or amending the merger agreement.

Background of the Merger

Each of IBKC’s and First Horizon’s boards of directors (which we refer to as the “IBKC board” and the “First Horizon board,” respectively) and their respective senior managements have from time to time separately engaged in reviews and discussions of long-term strategies and objectives and have considered ways to enhance their respective companies’ performance and prospects in light of competitive, regulatory and other developments, all with the goal of increasing long-term value for their respective shareholders and taking into account the interests of their other constituencies. The strategic reviews and discussions have focused on, among other things, the business and regulatory environment facing financial institutions generally and IBKC and First Horizon, respectively, in particular, as well as conditions and trends in the banking industry, including assessments of ongoing consolidation in the financial services industry and the benefits and risks to First Horizon and IBKC, respectively, and their shareholders of strategic combinations compared to the benefits and risks of continued operation as a stand-alone company. Factors assessed in connection with these reviews have included the risks and opportunities associated with operating in existing and new markets, competition, potential positive and negative expense and revenue synergies, regulatory burdens, interest rate environment and prospects, scale, credit risk, unpredictable market risk, and rapid changes in technology. For each of IBKC and First Horizon, these reviews have also included discussions with respect to potential transactions that would further its strategic objectives and the potential benefits and risks of any such transactions, and both companies have engaged in acquisitions as part of their corporate strategies.

66

Daryl Byrd, the President and Chief Executive Officer of IBKC, and Bryan Jordan, the Chairman and Chief Executive Officer of First Horizon, have periodically discussed with each other trends in the financial services industry and their respective institutions generally. These discussions occurred during meetings at investor and banking industry conferences and social settings. In 2016, Mr. Byrd and Mr. Jordan met and had a conceptual discussion regarding the possibility of a business combination between their companies, but both concluded they had other strategic initiatives of a higher priority to pursue at that time, including acquisitions of other banking organizations, and accordingly, no transaction discussions between the two companies were pursued. Mr. Jordan and Mr. Byrd did not further discuss a potential merger of First Horizon and IBKC until July 2019.

As part of its strategy, from time to time, First Horizon has evaluated potential strategic transactions with other banking institutions, occasionally acquired smaller banking institutions and pursued opportunities to acquire assets of other banking institutions, such as branch acquisitions. Prior to the execution of the merger agreement with IBKC, First Horizon had discussions with two institutions regarding potential strategic transactions, but neither of these discussions advanced beyond preliminary stages.

On March 19, 2019, at a regularly scheduled meeting of the IBKC board, the IBKC board discussed the changing competitive landscape highlighted by several recently announced large bank merger-of-equals transactions, as well as trends in deposit growth and technology spending by the largest U.S. banks. The IBKC board also discussed the potential opportunities for IBKC to engage in merger-and-acquisitions activity that could enhance long-term value for IBKC’s shareholders and its other constituencies in light of the increasing need for scale and technology investments in the banking industry and the current business and regulatory environment. Mr. Byrd updated the IBKC board on the work that management, with the assistance of IBKC’s financial advisors, had been doing to identify potential transaction counterparties for IBKC and to explore their level of interest in pursuing a strategic transaction. Mr. Byrd presented, and the IBKC board reviewed and discussed, a broad list of potential targets that IBKC could acquire, buyers who could acquire IBKC, and counterparties who could engage in a merger-of-equals transaction. The IBKC board indicated its support for management to continue, with the assistance of KBW and Goldman Sachs, reviewing potential counterparties for a strategic transaction and, where appropriate in their judgment, reaching out to such potential counterparties to explore their level of interest in pursuing a strategic transaction. At subsequent meetings of the IBKC board, Mr. Byrd further updated the IBKC board on the progress and results of this review and outreach process, including at the regularly scheduled July 16, 2019 board meeting where Mr. Byrd updated the board on preliminary conversations between representatives of First Horizon and IBKC regarding a possible business combination between the two companies. In addition, at this meeting the Board reviewed an overview provided by KBW and Goldman Sachs regarding current banking industry trends and a review of IBKC’s competitive position and potential merger partners.

At a meeting held July 22-23, 2019, Mr. Jordan briefed the First Horizon board on the general landscape for financial services mergers and acquisitions and the operating environment for financial institutions. At that meeting, Mr. Jordan reported on preliminary conversations between representatives of First Horizon and IBKC regarding a possible business combination between the two companies, and discussed with the First Horizon board the potential benefits and risks of considering IBKC as a partner in a strategic transaction as compared to other potential strategic combinations and other strategies that could be pursued by First Horizon. Following the July 22-23, 2019 First Horizon board meeting and continuing through the November 3, 2019 First Horizon board meeting, Mr. Jordan communicated updates to representatives of the First Horizon board regarding the status of discussions between representatives of First Horizon and IBKC and the progression of negotiations of key terms of the potential transaction, including with respect to compensation and retention matters.

On July 30, 2019, following discussions between representatives of First Horizon and IBKC, Mr. Byrd and Mr. Jordan spoke by telephone regarding First Horizon’s expressed interest in pursuing discussions regarding a possible strategic combination between the parties. During this discussion, Mr. Jordan and Mr. Byrd discussed that any strategic combination between the parties

67

would be structured as a merger of equals, and Mr. Jordan proposed that the parties utilize an at-the-market exchange ratio to be set at the signing of a merger agreement. Mr. Byrd indicated he would brief his board on First Horizon’s interest at IBKC’s upcoming off-site retreat, and if the IBKC board was supportive of engaging in discussions with First Horizon, would arrange to meet in person with Mr. Jordan shortly thereafter. During the course of subsequent negotiations between the parties, no alternate formulation of the exchange ratio was proposed by either party, and it was agreed that the precise exchange ratio would be calculated based on the closing prices of the shares of each company on the last trading day prior to announcement.

On August 12 and 13, 2019, the IBKC board held an off-site retreat with representatives of management in attendance. One segment of this retreat included a broad strategic review during which the IBKC board, together with members of management, conducted an in-depth review of IBKC’s strengths, weaknesses and potential challenges, including risks with respect to the interest rate environment, uncertainty regarding potential changes in the regulatory and political climate, technology spending relative to competitors, industry consolidation and the fact that the largest U.S. banks continue to maintain and increase their size and scale. IBKC’s management also noted that in recent periods interest rate spreads had compressed, making earnings more volatile, and that banks with more scale could invest more in fee income businesses as well as in technology and their brand marketing. The IBKC board, with the assistance of management, also engaged in a detailed review of strategic alternatives, which included a discussion regarding the possibility of IBKC remaining independent, engaging in a merger of equals, resuming its strategy of acquiring smaller banks, or being acquired in a transaction in which IBKC’s shareholders would receive a premium. The IBKC board discussed the key benefits and risks of engaging in each such course of action. IBKC’s management noted that there were a very limited number of viable acquisition candidates which could meaningfully enhance IBKC’s strategic position, and likely no potential acquirers for IBKC at such time that would pay a significant premium. Management provided the IBKC board with an update on potential merger partners which had been contacted and the results of these discussions. Management noted that of the more than 16 banks contacted by or which reached out to management or IBKC’s financial advisors over the past year, management had engaged in substantive discussions with six which management had determined, after evaluation with the assistance of IBKC’s financial advisors, represented the most attractive potential transaction opportunities, but only two counterparties (First Horizon and another institution we refer to as “Party A”) presented potentially attractive and actionable strategic transaction alternatives at that time.

At this same meeting the IBKC board also reviewed an overview provided by KBW and Goldman Sachs of potential financial considerations for evaluating whether to engage in a transaction with First Horizon or with Party A. Mr. Byrd also updated the IBKC board with regard to his conversation with Mr. Jordan on July 30, 2019 and with regard to other preliminary conversations between representatives of First Horizon and representatives of IBKC involving key terms of a potential transaction. Such key terms included structuring the transaction as an all-stock merger using an at-the-market exchange ratio, having a board and management split proportionate to the share ownership of the two companies’ respective stockholders, and the respective roles of Mr. Byrd and Mr. Jordan and of Mr. Byrd’s potential compensation and retention arrangements relating to such role. After a discussion of the potential risks and benefits in pursuing the various strategic alternatives, and in particular a transaction with First Horizon or Party A, the IBKC board authorized management to engage in further discussions with First Horizon while also continuing to explore other potential strategic alternatives, including the pending discussions with Party A.

On August 14, 2019, Mr. Byrd and Mr. Jordan met in Nashville, Tennessee to further discuss the potential benefits of a merger-of-equals transaction between IBKC and First Horizon including, among other things, potential earnings accretion, a strengthened and diversified franchise and greater scale to invest in technology and the customer experience. Mr. Byrd and Mr. Jordan noted that their two companies had held preliminary merger discussions several years earlier, and discussed the changes in the operating environment since then that created heightened benefits to resuming those discussions now, including the need for greater scale and volatile interest rate and economic trends

68

that created greater benefits from combining the two companies’ countercyclical businesses. Mr. Byrd and Mr. Jordan agreed that their respective chief financial officers should further discuss the compatibility of business models and operating cultures of the two companies as well as the feasibility and potential benefits of engaging in such a transaction.

On August 16, 22 and 30, 2019, the chief financial officers of IBKC and First Horizon discussed by telephone the process for engaging in due diligence of each other’s respective businesses, the importance of scale and technology, their respective approaches to client engagement and specialty businesses, their credit and risk management processes and other related topics. The chief financial officers concluded that IBKC’s and First Horizon’s businesses could complement each other and agreed to meet in person during the second week of September to continue their discussions.

Following these meetings and discussions, management of both companies agreed that further discussions would be facilitated by the exchange of nonpublic information. Accordingly, First Horizon and IBKC executed a mutual nondisclosure agreement on August 27, 2019.

On August 30, 2019, the Chief Executive Officer of Party A indicated to IBKC that, due to internal considerations, Party A was no longer interested in pursuing a strategic combination with IBKC at that time.

On September 11, 2019, the chief financial officers of IBKC and First Horizon met in Memphis, Tennessee to discuss the operational and financial feasibility of engaging in a merger-of-equals transaction, including a review of complementary businesses and markets, potential synergies, potential technology investments and employee culture and retention.

On September 12, 2019, Mr. Byrd and Mr. Jordan joined their respective chief financial officers in Memphis, Tennessee to further discuss the terms of a potential business combination. The discussion focused on both the “industrial logic” of the potential combination as well as key governance terms relevant to a merger of equals, including corporate name, headquarters, board split and similar matters.

On multiple occasions over the following weeks, the respective management teams of IBKC and First Horizon, with the assistance of their respective legal counsel and financial advisors, engaged in additional discussions with respect to corporate governance and a board and management structure designed to achieve meaningful participation by both companies in the future strategic direction of the combined company, the name of the combined company and the location of the combined company’s headquarters and major operational centers.

On September 16, 2019, the IBKC board held a regularly scheduled meeting at which representatives of management, KBW and Goldman Sachs were present. IBKC’s management briefed the IBKC board on the discussions with First Horizon to date, including the potential strategic benefits from increased scale and diversification as well as shareholder value creation through significant cost savings and synergies.

On September 27, 2019, Mr. Jordan and certain First Horizon independent directors had a meeting with Mr. Byrd and certain IBKC independent directors to continue discussions about a potential merger.

On October 1, 2019, the IBKC board held a special meeting, at which Mr. Byrd provided a summary of the September 27, 2019 meeting, as well as a follow-up telephone conversation he had with Mr. Jordan. The directors discussed the potential benefits and risks of the potential merger of equals with First Horizon. Mr. Byrd indicated to the IBKC board that he planned to meet with Mr. Jordan the following day to continue their discussions regarding the organization structure and related matters for the post-merger company, and that he would update the board following that meeting.

At a meeting on October 1, 2019, Mr. Jordan briefed the First Horizon board on the general landscape for financial services mergers and acquisitions and the operating environment for financial institutions. At that meeting, Mr. Jordan reported on the status of First Horizon’s bid to acquire branches to be divested by SunTrust Bank in connection with the merger of SunTrust Banks, Inc.

69

and BB&T Corporation and also reported on the status of discussions between First Horizon and IBKC regarding a potential merger of equals between the parties. As part of this report, Mr. Jordan described to the First Horizon board key terms of the potential merger of equals with IBKC that had been discussed to date.

On October 2, 2019, Mr. Byrd and Mr. Jordan met together with their respective chief financial officers to discuss a proposed organizational structure of the combined company, and agreed upon the identities of the combined company’s top eight executive officers who would report directly to the chief executive officer. The parties also agreed to begin preparing electronic data rooms in order to facilitate each party’s due diligence review of the other.

On October 7, 2019, the IBKC board held a special meeting with members of IBKC’s management in attendance. At this meeting, Mr. Byrd provided an overview of the meeting that he had with Mr. Jordan on October 2, 2019. The IBKC board then discussed the potential benefits of the proposed transaction, including that the combined business would have almost 500 branches and that IBKC executives would serve in key positions of the combined business. Mr. Byrd confirmed for the IBKC board that First Horizon was proposing a no-premium at-the-market exchange ratio. The IBKC board agreed that management should continue to engage with First Horizon to negotiate a potential transaction.

On October 15, 2019, the IBKC board held a special meeting with members of IBKC’s management in attendance. Mr. Byrd and other members of management updated the IBKC board on the status of negotiations with First Horizon. Mr. Byrd then reviewed the process conducted to-date with respect to looking at alternative types of strategic transactions and potential counterparties, including with respect to a potential acquisition of IBKC, potential targets that could be acquired by IBKC and potential merger-of-equals partners for IBKC, and updated the IBKC board on management’s current assessment of the potential benefits of a combination with First Horizon, including with respect to scale, complementary businesses, financial performance and value for IBKC’s shareholders and other constituencies. The IBKC board discussed the various strategic alternatives that the IBKC board and management had evaluated over the past year and before. The board also reviewed its previous discussions regarding the potential benefits and risks of a transaction with First Horizon as compared to other alternatives available to IBKC, including those described in “—IBKC’s Reasons for the Merger; Recommendation of IBKC Board of Directors” beginning on page 76. Following further discussion, the IBKC board authorized IBKC’s management, with the assistance of IBKC’s financial and legal advisors, to continue their discussions with First Horizon regarding a potential business combination transaction.

Starting on October 18, 2019, First Horizon and IBKC made available to each other in virtual data rooms various documents for mutual due diligence review. Management teams from each of First Horizon and IBKC and the parties’ respective advisors reviewed these materials. First Horizon and IBKC and their respective legal advisors engaged in extensive due diligence, including a significant number of due diligence meetings and telephone calls between the parties to discuss various topics. On October 18 and 19, 2019, members of First Horizon management, including Mr. Jordan, met with members of IBKC management, including Mr. Byrd, off-site, to discuss the integration of the companies’ businesses and management teams if a merger of equals of First Horizon and IBKC were to go forward. Following those meetings and continuing until the merger agreement was executed, members of the management teams of both companies continued to have discussions in person and by phone regarding the potential integration of First Horizon and IBKC.

On October 20, 2019, Sullivan & Cromwell, LLP (which we refer to as “Sullivan & Cromwell”), legal counsel to First Horizon, sent a term sheet to Simpson Thacher & Bartlett LLP (which we refer to as “Simpson Thacher”), legal counsel to IBKC, which outlined the proposed terms of Mr. Byrd’s employment with First Horizon following the closing of a transaction, which Simpson Thacher forwarded to Mr. Byrd and his personal legal counsel. The term sheet outlined certain key aspects of Mr. Byrd’s employment with First Horizon following the closing of the proposed transaction, including his roles as executive chairman and special advisor to the chief executive officer of First Horizon and his compensation for his service in such roles. From October 20 through 22, 2019, First

70

Horizon and Mr. Byrd, together with their respective legal counsel, continued to discuss such terms, which were later memorialized in the letter agreement between Mr. Byrd and First Horizon as described under “Interests of Certain IBKC Directors and Executive Officers in the Merger—Chairman Letter Agreement of Mr. Byrd.”

On October 22, 2019, the IBKC board met with members of IBKC’s management and representatives of Simpson Thacher, KBW and Goldman Sachs in attendance. IBKC’s management provided the IBKC board with an update regarding the status of the discussions and negotiations with First Horizon regarding the potential merger. KBW and Goldman Sachs reviewed with the IBKC board a preliminary analysis of certain financial aspects of the proposed transaction, including a comparison of the financial results of the two companies and their respective stock trading prices. A representative of Simpson Thacher then reviewed with the IBKC board certain legal matters, including the directors’ fiduciary duties, and also discussed illustrative terms that would be expected in a draft merger agreement to be provided by First Horizon as well as the current terms proposed by First Horizon for Mr. Byrd’s post-merger employment as reflected in the term sheet.

In the evening of October 22, 2019, Sullivan & Cromwell delivered an initial draft of the merger agreement to Simpson Thacher, which draft contemplated an all-stock merger based on a to-be-agreed fixed exchange ratio. Thereafter, the parties continued to negotiate the terms of, and exchanged drafts of, the merger agreement and related documentation.

On October 22 and 23, 2019, Mr. Jordan and other members of First Horizon senior management had discussions with Mr. Byrd and other members of IBKC senior management regarding business models, credit and other diligence matters.

On October 28, 2019, the IBKC board met, with members of management and representatives of KBW, Goldman Sachs and Simpson Thacher in attendance. The representatives of Simpson Thacher presented a summary of, and the IBKC board discussed, the principal terms of the merger agreement, taking into account revisions to be proposed by IBKC. The representatives of KBW and Goldman Sachs then discussed with the IBKC board, among other matters, the recent stock price performance of IBKC and First Horizon and other financial information of the two companies, as well as certain financial aspects of the proposed transaction. Members of management then reviewed with the IBKC board the status and process of IBKC’s ongoing due diligence regarding First Horizon, including IBKC’s preliminary diligence findings and the remaining diligence areas to be covered. Following the various presentations, the IBKC board discussed the terms, merits and risks of a potential transaction with First Horizon.

On October 28 and 29, 2019, the First Horizon board held a regularly scheduled two-day meeting. On October 28, 2019, Mr. Jordan provided the directors with information regarding the potential transaction with IBKC. On October 29, 2019, the First Horizon board met in executive session to discuss the potential transaction. Subsequently, members of management joined the meeting to provide directors with an overview of due diligence findings. Following the due diligence discussion, representatives of Morgan Stanley and Sullivan & Cromwell joined the meeting to discuss the financial, legal and regulatory implications of the potential merger. Representatives of Morgan Stanley provided directors with an overview of the strategic banking landscape, followed by a discussion of strategic alternatives to the proposed merger with IBKC and an overview of the transaction framework that had been discussed between First Horizon and IBKC senior management, including pricing and corporate governance terms. Morgan Stanley also provided directors with an overview of IBKC, prior mergers of equals in the banking industry and recent consolidation transactions in the banking industry and discussed certain preliminary considerations regarding the valuation of the two companies. Representatives of Sullivan & Cromwell next discussed the directors’ fiduciary duties in connection with the First Horizon board’s evaluation of the potential merger and strategic alternatives, the regulatory requirements for approvals of bank and bank holding company combination transactions, the regulatory environment for banks in general and for bank merger transactions in particular, and provided an overview of the terms of the draft of the potential merger agreement. The First Horizon board then continued in executive session to discuss the potential transaction. At the conclusion of the October 29, 2019 meeting, the

71

First Horizon board of directors authorized First Horizon senior management to continue negotiating the terms of the potential merger of equals with IBKC.

On October 31, 2019, First Horizon provided IBKC with a draft of Mr. Jordan’s letter agreement with First Horizon with respect to Mr. Jordan’s employment with First Horizon following the merger, to be effective upon, and subject to, the closing of the merger. The letter agreement provides for the terms described under “Interests of Certain First Horizon Directors and Executive Officers in the Merger—Letter Agreement between First Horizon and Mr. Jordan”, including a waiver of Mr. Jordan’s right to terminate his employment for “good reason” solely as a result of the contemplated succession plan in connection with the merger.

In the afternoon of November 1, 2019, the Compensation Committee of the IBKC board held a special meeting that was attended by representatives of Simpson Thacher. The representatives of Simpson Thacher reviewed and discussed with the committee the terms of (i) a draft agreement to be entered into between Mr. Byrd and First Horizon regarding his employment and service with the combined company upon the closing of the merger, (ii) drafts of proposed retention agreements to be entered into by IBKC with certain of its key executives, (iii) the proposed acceleration of certain performance-based restricted stock awards concurrently with the signing of the merger agreement and (iv) the terms of IBKC equity awards proposed to be granted to Mr. Byrd concurrently with the signing of the merger agreement (all of which are further described under “Interests of Certain IBKC Directors and Executive Officers in the Merger”). Representatives of Simpson Thacher also reviewed and discussed with the committee the proposed treatment of IBKC equity awards under the merger agreement. Following a discussion, the IBKC Compensation Committee unanimously approved each of the foregoing matters.

In addition, following the close of trading on Friday, November 1, 2019, management of each of IBKC and First Horizon, and their respective financial advisors, discussed the exchange ratio for the potential merger agreement, and such managements determined to propose to their respective boards of directors a fixed exchange ratio of 4.584 shares of First Horizon common stock for each share of IBKC common stock in an all-stock merger, which represented an at-the-market exchange ratio based on the parties’ respective closing stock prices on November 1, 2019.

In the morning of November 2, 2019, the IBKC board convened a special meeting with representatives of IBKC’s management, KBW, Goldman Sachs and Simpson Thacher in attendance. The representatives of Simpson Thacher reviewed, and the IBKC board discussed, the proposed governance arrangements of the combined company, including with respect to the roles of Mr. Byrd and Mr. Jordan, the composition of the board of directors and committees thereof, and First Horizon’s commitment to contribute $20 million to a newly-formed foundation focused on community support in the State of Louisiana. The representatives of KBW and Goldman Sachs then separately discussed with the IBKC board, among other matters, certain financial aspects of the proposed transaction based on the 4.584 exchange ratio and certain financial information, and reviewed their respective financial analyses. Thereafter, members of management, including Mr. Byrd, and financial advisors left the meeting, and representatives of Simpson Thacher reviewed the actions taken by the IBKC Compensation Committee on November 1, 2019, including the key terms of the proposed employment agreement between Mr. Byrd and First Horizon, the grant of restricted stock to Mr. Byrd and the proposed retention agreements with certain of IBKC’s executive officers.

Throughout the rest of November 2, 2019 and during the following day, First Horizon’s and IBKC’s management teams and their respective financial and legal advisors continued to negotiate and finalize the merger agreement and other transaction documents.

In the evening of November 3, 2019, the IBKC board convened another special meeting, with representatives of IBKC’s management, KBW, Goldman Sachs and Simpson Thacher in attendance. The representatives of KBW provided the financial presentation of KBW to the IBKC board, and KBW rendered to the IBKC board an opinion to the effect that, as of that date and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW as set forth in such opinion, the exchange ratio in the merger was fair, from a financial point of view, to the holders of IBKC common shares. The representatives of

72

Goldman Sachs then reviewed Goldman Sachs’s updated financial analyses of the proposed merger and rendered to the IBKC board Goldman Sachs’s oral opinion, subsequently confirmed in writing, attached to this joint proxy statement/prospectus as Annex D, to the effect that, as of November 3, 2019, the date of Goldman Sachs’ written opinion, and based upon and subject to the factors, qualifications and assumptions set forth in Goldman Sachs’ written opinion, the exchange ratio was fair from a financial point of view to the holders (other than First Horizon and its affiliates) of IBKC common shares. See “—Opinions of IBKC’s Financial Advisors” beginning on page 88. The representatives of Simpson Thacher in attendance reviewed the key terms of the merger agreement that had been negotiated since the previous meeting of the IBKC board and responded to questions regarding the potential transaction.

Following further discussion and after taking into consideration the matters discussed during the November 3, 2019 meeting and prior meetings of the IBKC board, including the factors described under “—IBKC’s Reasons for the Merger; Recommendation of IBKC Board of Directors” beginning on page 76, the IBKC board unanimously approved the merger agreement and the transactions contemplated thereby, including the proposed merger, and directed that the approval of the merger agreement be submitted to a vote at a meeting of the IBKC shareholders, and recommended that the IBKC shareholders approve the merger agreement.

At a special meeting on November 3, 2019, the First Horizon board considered the negotiated terms of the proposed merger and entry into the merger agreement by First Horizon. Morgan Stanley representatives reviewed with the First Horizon directors Morgan Stanley’s financial analysis summarized below under “—Opinion of First Horizon’s Financial Advisor” on page 79 and rendered to the board the oral opinion of Morgan Stanley, subsequently confirmed by delivery of a written opinion attached to this joint proxy statement/prospectus as Annex B, to the effect that, that as of the date of Morgan Stanley’s written opinion and subject to the various assumptions made, procedures followed, matters considered, and the qualifications and limitations on the scope of review undertaken by Morgan Stanley as set forth in its written opinion, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to First Horizon. Representatives of Sullivan & Cromwell provided a summary of the proposed terms of the merger agreement and described the resolutions the First Horizon directors would be asked to consider if they were to approve the merger. The directors then discussed the potential advantages and risks to First Horizon of the proposed merger, including the factors described under “—First Horizon’s Reasons for the Merger; Recommendation of First Horizon Board of Directors” beginning on page 73, and asked First Horizon senior management a number of questions about the proposed merger. At the conclusion of the meeting, the First Horizon board unanimously approved the resolutions, including approving the proposed merger and entry into the merger agreement by First Horizon.

Following the meetings of the First Horizon board and the IBKC board on November 3, 2019, and after finalizing the merger agreement, First Horizon and IBKC executed the merger agreement on the evening of November 3, 2019. The transaction was announced the morning of November 4, 2019, before the opening of the financial markets in New York, in a press release jointly issued by First Horizon and IBKC.

First Horizon’s Reasons for the Merger; Recommendation of First Horizon’s Board of Directors

After careful consideration, the First Horizon board, at a special meeting held on November 3, 2019, unanimously (i) determined that the merger agreement and the transactions contemplated thereby, including the merger, are advisable and fair to and in the best interests of First Horizon and its shareholders, (ii) declared First Horizon’s entry into the merger agreement advisable and (iii) adopted and approved the merger agreement and the consummation of the transactions contemplated thereby, including the merger and the charter amendment. Accordingly, the First Horizon board unanimously recommends that the First Horizon shareholders vote “FOR” the First Horizon merger proposal, “FOR” the First Horizon charter amendment proposal, “FOR” the First Horizon compensation proposal and “FOR” the First Horizon adjournment proposal.

73

In reaching the decision to approve the merger agreement, and to adopt the plan of merger and recommend approval of the plan of merger by First Horizon’s shareholders, the First Horizon board of directors evaluated the merger agreement, the merger and the other matters contemplated by the merger agreement in consultation with First Horizon senior management, as well as with First Horizon’s legal and financial advisors, and considered a number of factors, including the following:

| • |  | each of First Horizon’s and IBKC’s business, operations, financial condition, stock performance, asset quality, earnings and prospects, and legal and regulatory compliance. In reviewing these factors, including the information obtained through due diligence, the First Horizon board of directors considered IBKC’s financial condition and asset quality; that First Horizon’s and IBKC’s respective businesses, operations and risk profiles complement each other; that the companies’ separate earnings and prospects create the opportunity for the combined company to leverage complementary and diversified revenue streams and to have superior future earnings and prospects compared to First Horizon’s earnings and prospects on a stand-alone basis;
| • |  | the ability to leverage the combined company’s investments in technology across a greater number of customers;
| • |  | the combined company’s position as one of the largest financial services organizations in the southern United States in terms of total consolidated assets, loans, deposits and revenues;
| • |  | IBKC’s operations in high-growth southern U.S. banking markets, which enhances First Horizon’s footprint and deposit gathering opportunities in these fast growing markets;
| • |  | the compatibility of First Horizon’s and IBKC’s cultures and credit philosophies;
| • |  | the current environment in the financial services industry, including economic conditions and the interest rate and regulatory environments, increased operating costs resulting from regulatory and compliance mandates, increasing competition from both banks and non-bank financial and financial technology firms, current financial market conditions and the likely effects of these factors on First Horizon’s and the combined company’s potential growth, development, productivity and strategic options;
| • |  | the governance structure for the combined company, including the composition of the board of directors and executive management;
| • |  | First Horizon’s and IBKC’s past records of integrating acquisitions and of realizing expected financial and other benefits of such acquisitions;
| • |  | the anticipated pro forma financial impact of the merger on the combined company, including earnings, dividends, return on equity, tangible book value dilution (and earn-back period), asset quality, liquidity and regulatory capital levels;
| • |  | the expectation that the transaction would be generally tax-free for United States federal income tax purposes to First Horizon’s shareholders;
| • |  | the oral opinion of Morgan Stanley, subsequently confirmed in Morgan Stanley’s written opinion, to the effect that, as of the date of Morgan Stanley’s written opinion and subject to the various assumptions made, procedures followed, matters considered, and the qualifications and limitations on the scope of review undertaken by Morgan Stanley as set forth in its written opinion, the exchange ratio pursuant to the merger agreement was fair from a financial point of view to First Horizon, as more fully described below in the section “—Opinion of First Horizon’s Financial Advisor” beginning on page 79;
| • |  | the fact that the exchange ratio would be fixed, which the First Horizon board of directors believed was consistent with market practice for transactions of this type and with the strategic purpose of the transaction;

74

| • |  | its review and discussions with First Horizon’s senior management concerning the due diligence examination of the operations, financial condition and regulatory compliance programs and prospects of IBKC; and
| • |  | its review with its financial advisors of the financial terms of the merger agreement and its review with its legal advisors of the other terms of the merger agreement, including the representations, covenants, deal protection and termination provisions.

The First Horizon board of directors also considered the potential risks related to the transaction. The board concluded that the anticipated benefits of combining with IBKC were likely to outweigh these risks substantially. These potential risks included:

| • |  | the diversion of management focus and resources from other strategic opportunities and operational matters while working to implement the transaction and integrate the two companies;
| • |  | the possibility of encountering difficulties in achieving cost savings and synergies in the amounts currently estimated or within the time frame currently contemplated;
| • |  | the possibility of encountering difficulties in successfully integrating the businesses, operations and workforces of First Horizon and IBKC;
| • |  | certain anticipated merger-related costs;
| • |  | the regulatory and other approvals required in connection with the merger and the bank merger and the risk that such regulatory approvals will not be received in a timely manner or may impose unacceptable conditions;
| • |  | the possibility that divestitures may be required by regulatory authorities in one or more markets in which First Horizon and IBKC compete;
| • |  | the potential for legal claims challenging the merger;
| • |  | the merger’s effect on the combined company’s regulatory capital levels; and
| • |  | the other risks described under the sections entitled “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements.”

The foregoing discussion of the information and factors considered by the First Horizon board of directors is not intended to be exhaustive, but includes the material factors considered by the board. In reaching its decision to approve the merger agreement, the merger, and the other transactions contemplated by the merger agreement, the First Horizon board of directors did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The board considered all these factors as a whole, including discussions with, and questioning of, First Horizon’s management and First Horizon’s independent financial and legal advisors, and overall considered the factors to support its determination.

For the reasons set forth above, the First Horizon board of directors determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are advisable and in the best interests of First Horizon, and adopted and approved the merger agreement and the transactions contemplated by it.

In considering the recommendation of the First Horizon board of directors, you should be aware that certain directors and executive officers of First Horizon may have interests in the merger that are different from, or in addition to, interests of shareholders of First Horizon generally and may create potential conflicts of interest. The First Horizon board was aware of these interests and considered them when evaluating and negotiating the merger agreement, the merger and the other transactions contemplated by the merger agreement, and in recommending to First Horizon’s shareholders that they vote in favor of the First Horizon merger proposal. See “The Merger—Interests of Certain First Horizon Directors and Executive Officers in the Merger.”

75

It should be noted that this explanation of the reasoning of the First Horizon board of directors and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” on page 39.

IBKC’s Reasons for the Merger; Recommendation of IBKC’s Board of Directors

After careful consideration, the IBKC board, at a special meeting held on November 3, 2019, unanimously (i) determined that the merger agreement and the transactions contemplated thereby, including the merger, are in the best interests of IBKC, its shareholders and other constituencies, (ii) declared the merger agreement advisable and (iii) approved the execution, delivery and performance of the merger agreement and the consummation of the transactions contemplated thereby, including the merger. Accordingly, the IBKC board unanimously recommends that the IBKC shareholders vote “FOR” the IBKC merger proposal, “FOR” the IBKC compensation proposal and “FOR” the IBKC adjournment proposal.

In reaching its decision to approve and adopt the merger agreement and the transactions contemplated thereby, including the merger, and to recommend that IBKC’s shareholders approve the merger agreement, the IBKC board evaluated the merger agreement, the merger and the other transactions contemplated by the merger agreement in consultation with IBKC’s management, as well as with IBKC’s legal and financial advisors, and considered a number of factors, including the following:

| • |  | each of IBKC’s and First Horizon’s business, operations, financial condition, stock performance, asset quality, earnings and prospects. In reviewing these factors, including the information obtained through due diligence, the IBKC board considered the following:

| o |  | its view that the merger is a strategically compelling transaction that will create a stronger company, elevate growth and provide meaningful long-term value for the shareholders and other constituencies of both IBKC and First Horizon;
| o |  | its view that the combination strengthens the competitive position of the combined business in high-growth, demographically attractive Southern markets, with a pro forma bank branch footprint located in 15 of the top 20 Southern metropolitan statistical areas by population and in 11 states throughout the combined footprint;
| o |  | that shareholders of IBKC and First Horizon would benefit from expected annual cost synergies from maximizing efficiencies across the combined organization;
| o |  | its view that combined organization will offer a broader and more comprehensive suite of products and services for commercial, consumer and small business clients;
| o |  | its view that the combined company will be well positioned to capitalize on market opportunities and increase its client base through greater scale, strategic investments in advanced technologies and expanded product offerings;
| o |  | its view that IBKC and First Horizon share a commitment to their respective customers, communities, shareholders and the employees;
| o |  | its view that the combined company would have a more diversified business mix with the earnings streams from unique lending capabilities and distinct fee income businesses across a broader customer base;
| o |  | its view that, in light of the agreed-upon governance arrangements, the combined company would have a stronger, deeper leadership team with complementary expertise to drive enhanced operational performance, strategic growth and risk management;
| o |  | the anticipated impact of the transaction on the combined company, including the expected impact on financial metrics (including earnings per share, return on average assets, return on average tangible common equity and cash efficiency ratio);

76

| o |  | the historical performance of IBKC and First Horizon common shares; and
| o |  | its review and discussions with IBKC’s management and its legal advisors concerning the due diligence review of First Horizon;

| • |  | its familiarity of the current and prospective environment in the financial services industry, including economic conditions and the interest rate and regulatory environments, possible effects of scale, increased operating costs resulting from regulatory and compliance mandates, increasing competition from both nationwide banks and non-bank financial and financial technology firms, and current financial market conditions and the likely effects of these factors on IBKC’s and the combined company’s potential growth, development productivity and strategic options, and the likely effect of these factors on IBKC both with and without the proposed transaction;
| • |  | its views with respect to other strategic alternatives potentially available to IBKC, including continuing as a standalone company focusing exclusively on organic growth, making smaller acquisitions of other banks, transformative transactions (including large acquisitions or a merger of equals) and a transaction involving the sale of IBKC;
| • |  | the structure of the transaction as a merger of equals in which the IBKC board and IBKC’s management would have significant participation in the combined company; in particular, the provisions of the merger agreement setting forth the corporate governance of the combined company, including:

| o |  | that, until the third anniversary of the consummation of the merger, the board of directors of the combined company would consist of seventeen members, with eight from IBKC and nine from First Horizon; and
| o |  | that (i) Mr. Byrd, the current President and Chief Executive Officer of IBKC, would become and serve as the Executive Chairman of the combined company for two years following the consummation of the merger and (ii) other members of IBKC’s management would participate in the senior management of the combined company;

| • |  | the consistency of the transaction with IBKC’s business strategies, including achieving strong earnings growth, reaching new markets, improving customer attraction and retention, developing technology capabilities and focusing on cost management;
| • |  | the belief that the transaction is likely to increase value to shareholders, given that, from the perspective of an IBKC shareholder, the transaction is expected to be immediately accretive in 2020;
| • |  | the expectation that the transaction will be generally tax-free for United States federal income tax purposes to IBKC shareholders;
| • |  | the oral opinion of Goldman Sachs to the IBKC board to the effect that, subsequently confirmed in writing, as of November 3, 2019, the date of Goldman Sachs’ written opinion, and based upon and subject to the factors, qualifications and assumptions set forth in Goldman Sachs’ written opinion, the exchange ratio was fair from a financial point of view to the holders (other than First Horizon and its affiliates) of IBKC common shares, as more fully described below in the section “—Opinions of IBKC’s Financial Advisors—Opinion of Goldman Sachs & Co. LLC” beginning on page 98;
| • |  | the opinion, dated November 3, 2019, of KBW to the IBKC board to the effect that, as of that date and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW as set forth in such opinion, the exchange ratio in the merger was fair, from a financial point of view, to the holders of IBKC common shares, as more fully described below under “—Opinions of IBKC’s Financial Advisors—Opinion of Keefe, Bruyette & Woods, Inc.” beginning on page 88;
| • |  | the financial and other terms of the merger agreement, which IBKC reviewed with its outside financial and legal advisors, including:

77

| o |  | its expectation that, upon consummation of the merger, IBKC shareholders would own approximately 44% of the combined company;
| o |  | the fact that the exchange ratio is fixed, which the IBKC board believed was consistent with market practice for transactions of this type and with the strategic purpose of the transaction;
| o |  | the expectation of an immediate increase to IBKC shareholders in dividends per share based on anticipated dividend payments by the combined company, and the greater trading liquidity of First Horizon’s common stock;
| o |  | the fact that IBKC’s shareholders will have an opportunity to vote on the approval of the merger agreement;
| o |  | the right of the IBKC board under the merger agreement to withdraw its recommendation to the IBKC shareholders that they approve the merger agreement and the right of the First Horizon Board under the merger agreement to withdraw its recommendation to the First Horizon shareholders that they approve the merger agreement, in each case, in certain circumstances, as more fully described under “The Merger Agreement—Covenants and Agreements” and “The Merger Agreement—Termination of the Merger Agreement; Termination Fee” beginning on pages 147 and 155, respectively; and
| o |  | the rights of IBKC and First Horizon to terminate the merger agreement in certain circumstances, as more fully described under “The Merger Agreement—Termination of the Merger Agreement; Termination Fee” beginning on page 155.

The IBKC board also considered the potential risks related to the transaction. The IBKC board concluded that the anticipated benefits of combining with First Horizon were likely to outweigh these risks substantially. These potential risks included:

| • |  | the potential for the value of the merger consideration to be received by holders of shares of IBKC common stock to be adversely affected by a decrease in the trading price of First Horizon common stock;
| • |  | the potential risks associated with achieving anticipated efficiency improvements and cost reductions and savings and successfully integrating IBKC’s business, operations and workforce with those of First Horizon;
| • |  | the nature and amount of payments and other benefits to be received by IBKC’s management in connection with the merger pursuant to existing IBKC plans and compensation arrangements and the merger agreement;
| • |  | the potential risk of diverting management attention and resources from the operation of IBKC’s business and towards the completion of the merger and the integration of the two companies;
| • |  | the regulatory and other approvals required in connection with the merger and the expected likelihood that such regulatory approvals will be received in a reasonably timely manner and without the imposition of unacceptable conditions;
| • |  | the restrictions on the conduct of IBKC’s business during the period between execution of the merger agreement and the consummation of the merger, which could potentially delay or prevent IBKC from undertaking business opportunities that might arise or certain other actions it might otherwise take with respect to its operations absent the pendency of the merger;
| • |  | the potential effect of the merger on IBKC’s overall business, including its relationships with customers, employees, suppliers and regulators;
| • |  | the risk of losing key IBKC or First Horizon employees during the pendency of the merger and thereafter;

78

| • |  | the substantial costs to be incurred in connection with the merger, including the costs of integrating the businesses of IBKC and First Horizon, transaction fees, expenses and other payments that will or may arise from the merger;
| • |  | the fact that IBKC’s common shareholders would not be entitled to appraisal or dissenters’ rights in connection with the merger;
| • |  | that IBKC’s directors and executive officers may have interests in the merger that are different from or in addition to those of its shareholders generally, as more fully described under “—Interests of Certain IBKC Directors and Executive Officers in the Merger” beginning on page 119;
| • |  | that the merger may not be completed despite the combined efforts of IBKC and First Horizon or that completion may be unduly delayed, even if the required regulatory approvals are obtained and the requisite approvals are obtained from IBKC and First Horizon shareholders;
| • |  | the fact that IBKC may be obligated to pay First Horizon a termination fee of $156 million in certain circumstances, as more fully described under “The Merger Agreement—Termination of the Merger Agreement”; Termination Fee” beginning on page 155, may deter others from proposing an alternative transaction that may be more advantageous to IBKC’s shareholders; and
| • |  | the other risks described under “Risk Factors” and “Cautionary Statement Regarding Forward-Looking Statements” beginning on pages 41 and 39, respectively.

The foregoing discussion of the information and factors considered by the IBKC board is not intended to be exhaustive and may not include all of the factors considered by the IBKC board. In view of the variety of factors considered in connection with its consideration of the merger and the other transactions contemplated by the merger agreement, and the complexity of these matters, the IBKC board did not quantify or assign any relative weights to the factors considered, and individual directors may have given different weights to different factors. The above factors are not listed in any particular order of priority. The IBKC board considered all these factors as a whole.

In considering the recommendation of the IBKC board, you should be aware that certain directors and executive officers of IBKC may have interests in the merger that are different from, or in addition to, interests of shareholders of IBKC generally and may create potential conflicts of interest. The IBKC board was aware of these interests and considered them when evaluating and negotiating the merger agreement, the merger and the other transactions contemplated by the merger agreement, and in recommending to IBKC’s shareholders that they vote in favor of the IBKC merger proposal. See “The Merger—Interests of Certain IBKC Directors and Executive Officers in the Merger” beginning on page 119.

It should be noted that this explanation of the reasoning of the IBKC board and all other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed in “Cautionary Statement Regarding Forward-Looking Statements” on page 39.

Opinion of First Horizon’s Financial Advisor

First Horizon retained Morgan Stanley to provide it with financial advisory services in connection with a possible merger with IBKC, and, if requested by First Horizon, a financial opinion with respect thereto. First Horizon selected Morgan Stanley to act as its financial advisor based on Morgan Stanley’s qualifications, expertise and reputation and its knowledge of the business and affairs of First Horizon. Morgan Stanley rendered to the First Horizon board of directors at its special meeting on November 3, 2019, its oral opinion, subsequently confirmed by delivery of a written opinion dated November 3, 2019, that, as of such date, and based upon and subject to the various assumptions made, procedures followed, matters considered, and qualifications and limitations on the scope of review undertaken by Morgan Stanley as set forth therein, the exchange ratio pursuant to the merger agreement was fair, from a financial point of view, to First Horizon.

79

The full text of the written opinion of Morgan Stanley, dated November 3, 2019, is attached as Annex B and incorporated by reference into this joint proxy statement/prospectus. The opinion sets forth, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on the scope of the review undertaken by Morgan Stanley in rendering its opinion. Shareholders are urged to, and should, read the opinion carefully and in its entirety. Morgan Stanley’s opinion is directed to the First Horizon board of directors and addresses only the fairness, from a financial point of view, to First Horizon of the exchange ratio pursuant to the merger agreement as of the date of the opinion. Morgan Stanley’s opinion does not address any other aspect of the transactions contemplated by the merger agreement and does not constitute a recommendation to shareholders of First Horizon or shareholders of IBKC as to how to vote at any shareholders meetings held with respect to the merger or any other matter or whether to take any other action with respect to the merger. The summary of Morgan Stanley’s opinion set forth in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of the opinion. In addition, the opinion does not in any manner address the price at which First Horizon common stock will trade following the consummation of the merger or at any time.

For purposes of rendering its opinion, Morgan Stanley, among other things:

| • |  | reviewed certain publicly available financial statements and other business and financial information of IBKC and First Horizon, respectively;
| • |  | reviewed certain internal financial statements and other financial and operating data concerning IBKC and First Horizon, respectively;
| • |  | reviewed certain financial projections furnished to Morgan Stanley by the managements of IBKC and First Horizon, respectively, which were derived from a consensus of selected Wall Street equity research financial forecasts identified by the managements of IBKC and First Horizon, which forecasts were extrapolated for certain fiscal years based on the guidance of First Horizon (such forecasts are referred to herein as the “IBKC Street Forecasts” and the “First Horizon Street Forecasts,” respectively, and collectively as the “Street Forecasts”;
| • |  | reviewed information relating to certain strategic, financial and operational benefits anticipated from the merger, prepared by the managements of IBKC and First Horizon, respectively (such information is referred to herein as the “Synergies”;
| • |  | discussed the past and current operations and financial condition and the prospects of IBKC, including information relating to certain strategic, financial and operational benefits anticipated from the merger, with senior executives of IBKC;
| • |  | discussed the past and current operations and financial condition and the prospects of First Horizon, including information relating to certain strategic, financial and operational benefits anticipated from the merger, with senior executives of First Horizon;
| • |  | reviewed the pro forma impact of the merger on First Horizon’s earnings per share, tangible book value per share, common equity Tier 1 ratio, cash flow, consolidated capitalization and certain financial ratios;
| • |  | reviewed the reported prices and trading activity for IBKC common stock and First Horizon common stock;
| • |  | compared the financial performance of IBKC and First Horizon and the prices and trading activity of IBKC common stock and First Horizon common stock with that of certain other publicly-traded companies comparable with IBKC and First Horizon, respectively, and their securities;
| • |  | reviewed the financial terms, to the extent publicly available, of certain comparable merger transactions;
| • |  | participated in certain discussions and negotiations among representatives of IBKC and First Horizon and their financial and legal advisors;

80

| • |  | reviewed the merger agreement and certain related documents; and
| • |  | performed such other analyses, reviewed such other information and considered such other factors as Morgan Stanley deemed appropriate.

In arriving at its opinion, Morgan Stanley assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to it by First Horizon and IBKC, and formed a substantial basis for its opinion. At First Horizon’s direction, Morgan Stanley’s analysis relating to the business and financial prospects for IBKC and First Horizon for purposes of its opinion was made only on the basis of the Street Forecasts. Morgan Stanley was advised by IBKC and First Horizon, and assumed, with the consent of First Horizon, that the Street Forecasts were a reasonable basis upon which to evaluate the business and financial prospects of IBKC and First Horizon, respectively, and reflect the best currently available estimates of the future financial performance of IBKC and First Horizon, respectively. Morgan Stanley expressed no view as to the Street Forecasts or the assumptions on which they were based, including the selection of the equity research financial forecasts from which the Street Forecasts were derived. In addition, Morgan Stanley assumed that the merger will be consummated in accordance with the terms set forth in the merger agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the merger will be treated as a tax-free reorganization, pursuant to the Code, and that the definitive merger agreement would not differ in any material respect from the draft thereof furnished to Morgan Stanley. Morgan Stanley assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the proposed merger, no delays, limitations, conditions or restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed merger. Morgan Stanley is not an expert in the evaluation of allowance for loan losses, and it neither made an independent evaluation of the adequacy of the allowance for loan losses at IBKC or First Horizon, nor did it examine any individual loan credit files of IBKC or First Horizon nor was it requested to conduct such a review, and, as a result, Morgan Stanley assumed that the aggregate allowance for loan losses of IBKC and First Horizon, respectively, is adequate. Morgan Stanley is not a legal, tax, or regulatory advisor. Morgan Stanley is a financial advisor only and relied upon, without independent verification, the assessment of First Horizon and IBKC and their legal, tax, or regulatory advisors with respect to legal, tax, or regulatory matters.

IBKC Standalone Analyses

IBKC Public Trading Comparables Analysis

Morgan Stanley performed a public trading comparables analysis, which is designed to provide an implied trading value of a company by comparing it to selected companies with similar characteristics to the company. Morgan Stanley compared certain financial information of IBKC with publicly available information for the selected companies. The selected companies were chosen based on Morgan Stanley’s knowledge of the industry and because these companies have businesses that may be considered similar to IBKC’s and First Horizon’s. The selected companies consisted of all publicly traded banks in the United States with total assets between $25 billion and $50 billion, excluding thrifts and Puerto Rican banks. The selected companies consisted of:

| • |  | Signature Bank Corporation
| • |  | Synovus Financial Corporation
| • |  | TCF Financial Corporation
| • |  | East West Bancorp Inc.
| • |  | BOK Financial Corp
| • |  | Wintrust Financial Corporation
| • |  | F.N.B. Corporation
| • |  | Valley National Bancorp
| • |  | Texas Capital Bancshares Inc.
| • |  | Cullen/Frost Bankers, Inc.
| • |  | BankUnited, Inc.
| • |  | Associated Banc-Corp
| • |  | Hancock Whitney Corporation
| • |  | Sterling Bancorp
| • |  | Webster Financial Corp
| • |  | Umpqua Holdings Corporation
| • |  | Pinnacle Financial Partners, Inc.
| • |  | PacWest Bancorp
| • |  | Western Alliance Bancorporation
| • |  | Commerce Bancshares, Inc.

In all instances, multiples were based on closing stock prices on November 1, 2019. For each of the following analyses performed by Morgan Stanley, financial and market data for the selected companies were based on the most recent publicly available information and Wall Street consensus estimates.

With respect to the selected companies, the information Morgan Stanley presented included:

| • |  | multiple of price to estimated earnings per share for 2020, or Price / 2020E EPS; and
| • |  | multiple of price to tangible book value per share, or Price / Tangible Book Value

82

|  | Selected Companies’ Top Quartile |  | Selected Companies’ Median |  | Selected Companies’ Bottom Quartile |  | IBKC
Price / 2020E EPS |  |  |  | 11.3x |  |  |  |  | 10.8x |  |  |  |  | 9.9x |  |  |  |  | 10.9x |
Price / Tangible Book Value |  |  |  | 1.8x |  |  |  |  | 1.6x |  |  |  |  | 1.4x |  |  |  |  | 1.4x |

Based on the analysis of the relevant metrics for each of the selected banks, Morgan Stanley selected a range of multiples and applied this range of multiples to the relevant financial statistics for IBKC. For purposes of this analysis, Morgan Stanley utilized estimated earnings per share for 2020 as set forth in the IBKC Street Forecasts and tangible book value per share of IBKC as of September 30, 2019 as set forth in IBKC’s public filings.

Morgan Stanley estimated the implied trading value per share of IBKC common stock as of November 1, 2019, as follows:

|  | IBKC Metric |  | Multiple Statistic Range |  | Implied Value Per Share of IBKC Common Stock
Price / 2020E EPS |  |  | $ |  | 6.84 |  |  |  |  | 9.5x – 11.5x |  |  |  | $ |  | 64.98 – $78.66 |
Price / Tangible Book Value |  |  | $ |  | 52.68 |  |  |  |  | 1.4x – 1.8x |  |  |  | $ |  | 73.75 – $94.83 |

Morgan Stanley also did a regression-based analysis based on Price / Tangible Book Value versus 2020 return on tangible common equity for each of the selected companies. The range of estimated regression-based analysis implied values represents +/- 10% of the value implied by the regression line equation. The low-end range of $69.23 represents the implied value if IBKC were valued at 90% of the value implied by the regression line and the high-end range of $84.62 represents the implied value if IBKC were valued at 110% of the value implied by the regression line. For purposes of this analysis, Morgan Stanley utilized a 2020 return on tangible common equity estimate for IBKC of 12.7%, as set forth in the IBKC Street Forecasts.

No company in the public trading comparables analysis is identical to IBKC. In evaluating the group of selected companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of IBKC, such as the impact of competition on the business of IBKC or the industry generally, industry growth and the absence of any material adverse change in the financial condition and prospects of IBKC or the industry or in the financial markets in general. Mathematical analysis, such as determining the average or median, is not in itself a meaningful method of using peer group data.

IBKC Dividend Discount Analysis

Using the IBKC Street Forecasts and assuming, at the direction of First Horizon management, that IBKC would make distributions of capital in excess of the amount necessary to achieve a 9.25% common equity Tier 1 ratio level, Morgan Stanley performed a dividend discount analysis for IBKC on a standalone basis. Morgan Stanley calculated a range of implied values per share of IBKC common stock based on the sum of the discounted present values of (1) projected dividends on shares of IBKC common stock for the fourth quarter of 2019 through December 31, 2024 and (2) a projected terminal value of IBKC common stock as of December 31, 2024.

Morgan Stanley based its analysis on a range of terminal forward multiples of 9.0x to 11.0x to the terminal year 2025 estimated earnings, 7.4% to 9.4% discount rates, using the capital asset pricing model, and a 1.50% opportunity cost of cash. Utilizing the range of discount rates and terminal value multiples, Morgan Stanley derived an implied valuation range of present value indications per share of IBKC common stock ranging from $70.50 to $87.25.

First Horizon Standalone Analyses

First Horizon Public Trading Comparables Analysis

Morgan Stanley performed a public trading comparables analysis, which is designed to provide an implied trading value of a company by comparing it to selected companies with similar characteristics to the company. Morgan Stanley compared certain financial information of First Horizon with publicly available information for the selected companies, as identified above under “IBKC Standalone Analyses—IBKC Public Trading Comparables Analysis.”

In all instances, multiples were based on closing stock prices on November 1, 2019. For each of the following analyses performed by Morgan Stanley, financial and market data for the selected companies were based on the most recent publicly available information and Wall Street consensus estimates.

With respect to the selected companies, the information Morgan Stanley presented included:

| • |  | multiple of price to estimated earnings per share for 2020, or Price / 2020E EPS; and
| • |  | multiple of price to tangible book value per share, or Price / Tangible Book Value

|  | Selected Companies’ Top Quartile |  | Selected Companies’ Median |  | Selected Companies’ Bottom Quartile |  | First Horizon
Price / 2020E EPS |  |  |  | 11.3x |  |  |  |  | 10.8x |  |  |  |  | 9.9x |  |  |  |  | 10.1x |
Price / Tangible Book Value |  |  |  | 1.8x |  |  |  |  | 1.6x |  |  |  |  | 1.4x |  |  |  |  | 1.7x |

Based on the analysis of the relevant metrics for each of the selected banks, Morgan Stanley selected a range of multiples and applied this range of multiples to the relevant financial statistics for First Horizon. For purposes of this analysis, Morgan Stanley utilized estimated earnings per share for 2020 as set forth in the First Horizon Street Forecasts and tangible book value per share of First Horizon as of September 30, 2019 as set forth in First Horizon’s public filings.

Morgan Stanley estimated the implied trading value per share of First Horizon common stock as of November 1, 2019, as follows:

|  | First Horizon Metric |  | Multiple Statistic Range |  | Implied Value Per Share of First Horizon Common Stock
Price / 2020E EPS |  |  | $ |  | 1.61 |  |  |  |  | 9.5x – 11.5x |  |  |  | $ |  | 15.31 – $18.53 |
Price / Tangible Book Value |  |  | $ |  | 9.76 |  |  |  |  | 1.4x – 1.8x |  |  |  | $ |  | 13.66 – $17.56 |

Morgan Stanley also did a regression-based analysis based on Price / Tangible Book Value versus 2020 return on tangible common equity for each of the selected companies. The range of estimated regression-based analysis implied values represents +/- 10% of the value implied by the regression line equation. The low-end range of $15.51 represents the implied value if First Horizon were valued at 90% of the value implied by the regression line and the high-end range of $18.95 represents the implied value if First Horizon were valued at 110% of the value implied by the regression line. For purposes of this analysis, Morgan Stanley utilized a 2020 return on tangible common equity estimate for First Horizon of 15.9%, as set forth in the First Horizon Street Forecasts.

No company in the public trading comparables analysis is identical to First Horizon. In evaluating the group of selected companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of First Horizon, such as the impact of competition on the business of First Horizon or the industry generally, industry growth and the absence of any material adverse change in the financial condition and prospects of First Horizon or the industry or in the financial markets in general. Mathematical analysis, such as determining the average or median, is not in itself a meaningful method of using peer group data.

First Horizon Dividend Discount Analysis

Using the First Horizon Street Forecasts and assuming, at the direction of First Horizon management, that First Horizon would make distributions of capital in excess of the amount necessary to achieve a 9.25% common equity Tier 1 ratio level, Morgan Stanley performed a dividend discount analysis for First Horizon on a standalone basis. Morgan Stanley calculated a range of implied values per share of First Horizon common stock based on the sum of the discounted present values of (1) projected dividends on shares of First Horizon common stock for the fourth quarter of 2019 through December 31, 2024 and (2) a projected terminal value of First Horizon common stock as of December 31, 2024.

Morgan Stanley based its analysis on a range of terminal forward multiples of 9.0x to 11.0x to the terminal year 2025 estimated earnings, 7.3% to 9.3% discount rates, using the capital asset pricing model, and a 1.50% opportunity cost of cash. Utilizing the range of discount rates and terminal value multiples, Morgan Stanley derived an implied valuation range of present value indications per share of First Horizon common stock ranging from $15.30 to $19.32.

Contribution Analysis

Morgan Stanley compared IBKC’s and First Horizon’ respective percentage contributions for certain financial metrics described below to the combined company. Morgan Stanley utilized First Horizon’s and IBKC’s respective balance sheet as of September 30, 2019 and estimates of net income for calendar years 2020 and 2021 as set forth in the Street Forecasts. The following table summarizes Morgan Stanley’s analysis, as compared to the 56% (First Horizon) and 44% (IBKC) ownership of the combined company resulting from the exchange ratio of 4.584x provided for in the merger agreement:

|  | IBKC Contribution |  | First Horizon Contribution
Total Assets |  |  |  | 42 | % |  |  |  |  | 58 | % |

Exchange Ratios Analysis

Using the implied value per share reference ranges for IBKC and First Horizon indicated in the public trading comparables analyses and the dividend discount analyses of IBKC and First Horizon described above, and the percentage contributions indicated in the contribution analyses described above, Morgan Stanley calculated ranges of implied exchange ratios of IBKC common stock into First Horizon common stock. Other than for the contribution analyses, the implied exchange ratios represent the range of high-to-low and low-to-high exchange ratios implied by the respective valuation analyses. For the contribution analyses, the implied exchange ratio represents the high and low exchange ratios implied by the individual balance sheet and net income contribution analyses. This implied exchange ratio analysis indicated the following implied exchange ratio reference ranges, as compared to the exchange ratio of 4.584x provided for in the merger agreement:

|  | Implied Exchange Ratio
Public Trading Comparables |  |
Price / 2020 E EPS |  |  |  | 3.506x – 5.138x |
Price / Tangible Book Value |  |  |  | 4.200x – 6.943x |

Contribution Analysis |  |  |  | 4.224x – 5.400x |

85

Morgan Stanley also reviewed the historical trading prices for IBKC common stock and First Horizon common stock from November 1, 2016 to November 1, 2019 and calculated implied historical exchange ratios by dividing the average daily closing price per share of IBKC common stock by the average daily closing price per share of First Horizon common stock. This implied historical exchange ratio analysis indicated the following historical exchange ratios, as compared to the exchange ratio of 4.584x provided for in the merger agreement:

|  | Implied Exchange Ratio
November 1, 2019 |  |  |  | 4.584x |
One-Month Average |  |  |  | 4.671x |
Two-Month Average |  |  |  | 4.632x |
Three-Month Average |  |  |  | 4.587x |
Six-Month Average |  |  |  | 4.882x |
One-Year Average |  |  |  | 4.911x |
Three-Year Average |  |  |  | 4.513x |

The historical exchange ratios were presented for reference purposes only, and were not relied upon for valuation purposes.

Pro Forma Accretion/Dilution Analysis

Morgan Stanley reviewed and analyzed the estimated pro forma impact of the merger on (i) projected accretion/(dilution) to holders of First Horizon common stock for the years 2021 and 2022, (ii) tangible book value per share as of the closing date and (iii) common equity Tier 1 ratio as of the closing date, in each case based on the Street Forecasts and the Synergies. For purposes of the tangible book value per share and common equity Tier 1 ratio analyses, Morgan Stanley utilized an estimated closing date of June 30, 2020. Based on these analyses, Morgan Stanley calculated (a) an estimated pro forma accretive impact to earnings per share for holders of First Horizon common stock of 12% and 16% for 2021 and 2022, respectively, (b) an estimated pro forma dilutive impact on tangible book value per share as of the closing date of 5%, assuming the full impact of one-time merger-related expenses, and (c) an estimated pro forma dilutive impact on common equity Tier 1 ratio as of the closing date of 20 basis points, assuming the impact of estimated one-time merger-related expenses incurred prior to or around closing. Any such estimates are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by the estimates.

Pro Forma Dividend Discount Analysis

Using the Street Forecasts, the Synergies and other fair market value and transaction adjustments and assuming, at the direction of First Horizon management, that First Horizon would make distributions of capital in excess of the amount necessary to achieve a 9.25% common equity Tier 1 ratio level, Morgan Stanley performed a dividend discount analysis for First Horizon on a pro forma basis after giving effect to the merger. Morgan Stanley calculated a range of implied values per share of First Horizon common stock based on the sum of the discounted present values of (1) projected dividends on shares of First Horizon common stock as of the estimated closing date for the third quarter of 2020 through December 31, 2025 and (2) a projected terminal value of First Horizon common stock as of December 31, 2025.

Morgan Stanley based its analysis on a range of terminal forward multiples of 9.0x to 11.0x to the terminal year 2026 estimated earnings, 7.3% to 9.3% discount rates, using the capital asset pricing model, and a 1.50% opportunity cost of cash. Utilizing the range of discount rates and terminal value multiples, Morgan Stanley derived an implied valuation range of present value indications per share of First Horizon common stock ranging from $17.30 to $22.01.

General

In connection with the review of the merger by First Horizon’s board of directors, Morgan Stanley performed a variety of financial and comparative analyses for purposes of rendering its opinion. The preparation of a financial opinion is a complex process and is not necessarily susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any analysis or factor it considered. Morgan Stanley believes that selecting any portion of its analyses, without considering all analyses as a whole, would create an incomplete view of the process underlying its analyses and opinion. In addition, Morgan Stanley may have given various analyses and factors more or less weight than other analyses and factors, and may have deemed various assumptions more or less probable than other assumptions. As a result, the ranges of valuations resulting from any particular analysis described above should not be taken to be Morgan Stanley’s view of the actual value of First Horizon or IBKC. In performing its analyses, Morgan Stanley made numerous assumptions with regard to industry performance, general business, economic, market and financial conditions and other matters which are beyond the control of First Horizon or IBKC. Any estimates contained in Morgan Stanley’s analyses are not necessarily indicative of future results or actual values, which may be significantly more or less favorable than those suggested by such estimates.

Morgan Stanley conducted the analyses described above solely as part of its analysis of the fairness, from a financial point of view to First Horizon of the exchange ratio pursuant to the merger agreement, and in connection with the delivery of its oral opinion, and its subsequent written opinion, to First Horizon’s board of directors. These analyses do not purport to be appraisals or to reflect the prices at which First Horizon common stock or IBKC common stock might actually trade. Morgan Stanley expressed no opinion or recommendation as to how the shareholders of First Horizon and IBKC should vote at the shareholders’ meetings to be held in connection with the merger.

The exchange ratio was determined through arm’s-length negotiations between First Horizon and IBKC and was approved by First Horizon’s board of directors. Morgan Stanley provided advice to First Horizon during these negotiations but did not, however, recommend any specific exchange ratio to First Horizon or IBKC, or that any specific exchange ratio constituted the only appropriate exchange ratio for the merger.

Morgan Stanley’s opinion and its presentation to First Horizon’s board of directors was one of many factors taken into consideration by First Horizon’s board of directors in deciding to approve, adopt and authorize the merger agreement and approve the transactions contemplated thereby, including the merger. Consequently, the analyses as described above should not be viewed as determinative of the opinion of First Horizon’s board of directors with respect to the exchange ratio pursuant to the merger agreement or of whether First Horizon’s board of directors would have been willing to agree to a different exchange ratio. Morgan Stanley’s opinion was approved by a committee of Morgan Stanley investment banking and other professionals in accordance with its customary practice.

First Horizon’s board of directors retained Morgan Stanley based upon Morgan Stanley’s qualifications, experience and expertise. Morgan Stanley is an internationally recognized investment banking and advisory firm. Morgan Stanley is a global financial services firm engaged in the securities, investment management and individual wealth management businesses. Its securities business is engaged in securities underwriting, trading and brokerage activities, foreign exchange, commodities and derivatives trading, prime brokerage, as well as providing investment banking, financing and financial advisory services. Morgan Stanley, its affiliates, directors and officers may at any time invest on a principal basis or manage funds that invest, hold long or short positions, finance positions, and may trade or otherwise structure and effect transactions, for their own account or the accounts of its customers, in debt or equity securities or loans of First Horizon, IBKC or any other company, or any currency or commodity, that may be involved in this transaction, or any related derivative instrument.

Under the terms of its engagement letter, as compensation for its services relating to the merger, First Horizon has agreed to pay Morgan Stanley a fee of $28 million in the aggregate, $5 million of

87

which was payable upon the rendering of its opinion and $23 million of which is contingent upon the consummation of the merger. First Horizon has also agreed to reimburse Morgan Stanley for its reasonable expenses incurred in performing its services. In addition, First Horizon has agreed to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses, including certain liabilities under the federal securities laws, related to or arising out of Morgan Stanley’s engagement. During the two years preceding the date of delivery of Morgan Stanley’s written opinion, Morgan Stanley and its affiliates have provided financial advisory and financing services to First Horizon for which Morgan Stanley and its affiliates have received aggregate fees of approximately $5 million. Morgan Stanley may also seek to provide financial advisory and financing services to First Horizon, IBKC and their respective affiliates in the future and would expect to receive fees for the rendering of these services.

Opinions of IBKC’s Financial Advisors

Opinion of Keefe, Bruyette & Woods, Inc.

IBKC engaged KBW to render financial advisory and investment banking services to IBKC, including an opinion to the IBKC board of directors as to the fairness, from a financial point of view, to the holders of IBKC common stock of the exchange ratio in the proposed merger of IBKC with and into First Horizon. IBKC selected KBW because KBW is a nationally recognized investment banking firm with substantial experience in transactions similar to the merger. As part of its investment banking business, KBW is continually engaged in the valuation of financial services businesses and their securities in connection with mergers and acquisitions.

As part of its engagement, representatives of KBW participated telephonically in the meeting of the IBKC board held on November 3, 2019, at which the IBKC board evaluated the proposed merger. At this meeting, KBW rendered to the IBKC board an opinion to the effect that, as of such date and subject to the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW as set forth in its opinion, the exchange ratio in the proposed merger was fair, from a financial point of view, to the holders of IBKC common stock. The IBKC board approved the merger agreement at this meeting.

The description of the opinion set forth herein is qualified in its entirety by reference to the full text of the opinion, which is attached as Annex C to this document and is incorporated herein by reference, and describes the procedures followed, assumptions made, matters considered, and qualifications and limitations on the review undertaken by KBW in preparing the opinion.

KBW’s opinion speaks only as of the date of the opinion. The opinion was for the information of, and was directed to, the IBKC board (in its capacity as such) in connection with its consideration of the financial terms of the merger. The opinion addressed only the fairness, from a financial point of view, of the exchange ratio in the merger to the holders of IBKC common stock. It did not address the underlying business decision of IBKC to engage in the merger or enter into the merger agreement or constitute a recommendation to the IBKC board in connection with the merger, and it does not constitute a recommendation to any holder of IBKC common stock or any shareholder of any other entity as to how to vote in connection with the merger or any other matter, nor does it constitute a recommendation regarding whether or not any such shareholder should enter into a voting, shareholders’, or affiliates’ agreement with respect to the merger or exercise any dissenters’ or appraisal rights that may be available to such shareholder.

KBW’s opinion was reviewed and approved by KBW’s Fairness Opinion Committee in conformity with its policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

In connection with the opinion, KBW reviewed, analyzed and relied upon material bearing upon the financial and operating condition of IBKC and First Horizon and bearing upon the merger, including, among other things:

| • |  | certain regulatory filings of IBKC and First Horizon and their respective subsidiaries, including the quarterly reports on Form FR Y-9C and call reports filed with respect to each quarter during the three-year period ended December 31, 2018 as well as the quarters ended March 31, 2019 and June 30, 2019, and in the case of IBERIABANK and First Horizon Bank, September 30, 2019;
| • |  | certain other interim reports and other communications of IBKC and First Horizon to their respective shareholders; and
| • |  | other financial information concerning the businesses and operations of IBKC and First Horizon that was furnished to KBW by IBKC and First Horizon or which KBW was otherwise directed to use for purposes of KBW’s analyses.

KBW’s consideration of financial information and other factors that it deemed appropriate under the circumstances or relevant to its analyses included, among others, the following:

| • |  | the historical and current financial position and results of operations of IBKC and First Horizon;
| • |  | the assets and liabilities of IBKC and First Horizon;
| • |  | a comparison of certain financial and stock market information for IBKC and First Horizon with similar information for certain other companies the securities of which were publicly traded;
| • |  | financial and operating forecasts and projections of IBKC that were prepared by IBKC management, provided to and discussed with KBW by IBKC management, and used and relied upon by KBW at the direction of such management and with the consent of the IBKC board;
| • |  | financial and operating forecasts and projections of First Horizon with respect to fiscal years 2019 and 2020 that were prepared by First Horizon management, provided to and discussed with KBW by First Horizon management, and used and relied upon by KBW based on such discussions, at the direction of IBKC management and with the consent of the IBKC board;
| • |  | financial and operating forecasts and projections of First Horizon with respect to certain fiscal years beyond 2020 that were prepared by IBKC management, provided to and discussed with KBW by IBKC management and used and relied upon by KBW at the direction of such management and with the consent of the IBKC board; and

89

| • |  | estimates regarding certain pro forma financial effects of the merger on First Horizon (including, without limitation, the cost savings and related expenses expected to result or be derived from the merger) that were prepared by First Horizon management, provided to and discussed with KBW by First Horizon management, and used and relied upon by KBW based on such discussions, at the direction of IBKC management and with the consent of the IBKC board.

KBW also performed such other studies and analyses as it considered appropriate and took into account its assessment of general economic, market and financial conditions and its experience in other transactions, as well as its experience in securities valuation and knowledge of the banking industry generally. KBW also participated in discussions held by the managements of IBKC and First Horizon regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters as KBW deemed relevant to its inquiry.

In conducting its review and arriving at its opinion, KBW relied upon and assumed the accuracy and completeness of all of the financial and other information that was provided to KBW or that was publicly available and KBW did not independently verify the accuracy or completeness of any such information or assume any responsibility or liability for such verification, accuracy or completeness. KBW relied upon the management of IBKC as to the reasonableness and achievability of the financial and operating forecasts and projections of IBKC and the financial and operating forecasts and projections of First Horizon with respect to certain fiscal years beyond 2020, all as referred to above (and the assumptions and bases for all such information), and KBW assumed that all such information was reasonably prepared on a basis reflecting the best currently available estimates and judgments of such management and that the forecasts, projections and estimates reflected in such information would be realized in the amounts and in the time periods estimated by such management. KBW further relied upon First Horizon management, with the consent of IBKC, as to the reasonableness and achievability of the financial and operating forecasts and projections of First Horizon (with respect to fiscal years 2019 and 2020) and the estimates regarding certain pro forma financial effects of the merger on First Horizon (including, without limitation, the cost savings and related expenses expected to result or be derived from the merger), all as referred to above (and the assumptions and bases for all such information), and KBW assumed that all such information was reasonably prepared on a basis reflecting the best currently available estimates and judgments of First Horizon management and that the forecasts, projections and estimates reflected in such information would be realized in the amounts and in the time periods estimated by such management.

It is understood that the foregoing financial information of IBKC and First Horizon that was provided to KBW was not prepared with the expectation of public disclosure and that the foregoing financial information was based on numerous variables and assumptions that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions) and, accordingly, actual results could vary significantly from those set forth in such information. KBW assumed, based on discussions with the respective managements of IBKC and First Horizon and with the consent of the IBKC board, that all such information provided a reasonable basis upon which KBW could form its opinion and KBW expressed no view as to any such information or the assumptions or bases therefor. KBW relied on all such information without independent verification or analysis and did not in any respect assume any responsibility or liability for the accuracy or completeness thereof.

KBW also assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either IBKC or First Horizon since the date of the last financial statements of each such entity that were made available to KBW. KBW is not an expert in the independent verification of the adequacy of allowances for loan and lease losses and KBW assumed, without independent verification and with IBKC’s consent, that the aggregate allowances for loan and lease losses for IBKC and First Horizon are adequate to cover such losses. In rendering its opinion, KBW did not make or obtain any evaluations or appraisals or physical inspection of the property, assets or liabilities (contingent or otherwise) of IBKC or First Horizon, the collateral

90

securing any of such assets or liabilities, or the collectability of any such assets, nor did KBW examine any individual loan or credit files, nor did it evaluate the solvency, financial capability or fair value of IBKC or First Horizon under any state or federal laws, including those relating to bankruptcy, insolvency or other matters. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Because such estimates are inherently subject to uncertainty, they should not be taken as KBW’s view of the actual value of such companies or assets.

KBW assumed, in all respects material to its analyses:

| • |  | that the merger and any related transactions (including, without limitation, the bank subsidiary merger) would be completed substantially in accordance with the terms set forth in the merger agreement (the final terms of which KBW assumed would not differ in any respect material to KBW’s analyses from the draft reviewed by KBW and referred to above) with no adjustments to the exchange ratio and with no other consideration or payments in respect of IBKC common stock;
| • |  | that the representations and warranties of each party in the merger agreement and in all related documents and instruments referred to in the merger agreement were true and correct;
| • |  | that each party to the merger agreement and all related documents would perform all of the covenants and agreements required to be performed by such party under such documents;
| • |  | that there were no factors that would delay or subject to any adverse conditions, any necessary regulatory or governmental approval for the merger or any related transactions and that all conditions to the completion of the merger and any related transaction would be satisfied without any waivers or modifications to the merger agreement or any of the related documents; and
| • |  | that in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the merger and any related transaction, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, would be imposed that would have a material adverse effect on the future results of operations or financial condition of IBKC, First Horizon or the pro forma entity, or the contemplated benefits of the merger, including without limitation the cost savings and related expenses expected to result or be derived from the merger.

KBW assumed that the merger would be consummated in a manner that complies with the applicable provisions of the Securities Act, the Exchange Act and all other applicable federal and state statutes, rules and regulations. KBW was further advised by representatives of IBKC that IBKC relied upon advice from its advisors (other than KBW) or other appropriate sources as to all legal, financial reporting, tax, accounting and regulatory matters with respect to IBKC, First Horizon, the merger and any related transaction, and the merger agreement. KBW did not provide advice with respect to any such matters.

KBW’s opinion addressed only the fairness, from a financial point of view, as of the date of the opinion, of the exchange ratio in the merger to the holders of IBKC common stock. KBW expressed no view or opinion as to any other terms or aspects of the merger or any term or aspect of any related transaction, including without limitation, the form or structure of the merger or any such related transaction, any consequences of the merger or any such related transaction to IBKC, its shareholders, creditors or otherwise, the treatment of IBKC’s outstanding preferred stock in the merger, or any terms, aspects, merits or implications of any employment, consulting, voting, support, shareholder or other agreements, arrangements or understandings contemplated or entered into in connection with the merger or otherwise. KBW’s opinion was necessarily based upon conditions as they existed and could be evaluated on the date of such opinion and the information made available to KBW through such date. Developments subsequent to the date of KBW’s opinion may have affected, and may affect, the conclusion reached in KBW’s opinion and KBW did not and does not

91

have an obligation to update, revise or reaffirm its opinion. KBW’s opinion did not address, and KBW expressed no view or opinion with respect to:

| • |  | the underlying business decision of IBKC to engage in the merger or enter into the merger agreement;
| • |  | the relative merits of the merger as compared to any strategic alternatives that are, have been or may be available to or contemplated by IBKC or the IBKC board;
| • |  | the fairness of the amount or nature of any compensation to any of IBKC’s officers, directors or employees, or any class of such persons, relative to the compensation to the holders of IBKC common stock;
| • |  | the effect of the merger or any related transaction on, or the fairness of the consideration to be received by, holders of any class of securities of IBKC (other than the holders of IBKC common stock, solely with respect to the exchange ratio, as described in KBW’s opinion and not relative to the consideration to be received by holders of any other class of securities) or holders of any class of securities of First Horizon or any other party to any transaction contemplated by the merger agreement;
| • |  | the actual value of First Horizon common stock to be issued in the merger;
| • |  | the prices, trading range or volume at which IBKC common stock and First Horizon common stock would trade following the public announcement of the merger or the prices, trading range or volume at which First Horizon common stock would trade following the consummation of the merger;
| • |  | any advice or opinions provided by any other advisor to any of the parties to the merger or any other transaction contemplated by the merger agreement; or
| • |  | any legal, regulatory, accounting, tax or similar matters relating to IBKC, First Horizon, their respective shareholders, or relating to or arising out of or as a consequence of the merger or any related transaction (including the subsidiary bank merger), including whether or not the merger would qualify as a tax-free reorganization for United States federal income tax purposes.

In performing its analyses, KBW made numerous assumptions with respect to industry performance, general business, economic, market and financial conditions and other matters, which are beyond the control of KBW, IBKC and First Horizon. Any estimates contained in the analyses performed by KBW are not necessarily indicative of actual values or future results, which may be significantly more or less favorable than suggested by these analyses. Additionally, estimates of the value of businesses or securities do not purport to be appraisals or to reflect the prices at which such businesses or securities might actually be sold. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. In addition, KBW’s opinion was among several factors taken into consideration by the IBKC board in making its determination to approve the merger agreement and the merger. Consequently, the analyses described below should not be viewed as determinative of the decision of the IBKC board with respect to the fairness of the exchange ratio. The type and amount of consideration payable in the merger were determined through negotiation between IBKC and First Horizon and the decision of IBKC to enter into the merger agreement was solely that of the IBKC board.

The following is a summary of the material financial analyses presented by KBW to the IBKC board in connection with its opinion. The summary is not a complete description of the financial analyses underlying the opinion or the presentation made by KBW to the IBKC board, but summarizes the material analyses performed and presented in connection with such opinion. The financial analyses summarized below include information presented in tabular format. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex analytic process involving various determinations as to appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. Therefore, a fairness opinion is not readily susceptible to partial analysis or summary description. In arriving at

92

its opinion, KBW did not attribute any particular weight to any analysis or factor that it considered, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Accordingly, KBW believes that its analyses and the summary of its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on the information presented below in tabular format, without considering all analyses and factors or the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of the process underlying its analyses and opinion.

Implied Transaction Statistics for the Proposed Merger. Utilizing an implied transaction value for the proposed merger of $74.77 per outstanding share of IBKC common stock based on the 4.584x exchange ratio in the proposed merger and the closing price of First Horizon common stock on November 1, 2019, KBW reviewed with the IBKC board of directors, among other things, the following implied transaction statistics for the proposed merger, which (as indicated below) were based on historical financial information of IBKC and either earnings per share (“EPS”) consensus “street estimates” for IBKC or internal EPS estimates for IBKC provided by IBKC management:

Price / September 30, 2019 Tangible Book Value per Share |  |  |  | 1.42x |

|  | Based on “Street” Estimates |  | Based on Internal Estimates
Price / 2019 Earnings per Share |  |  |  | 10.5x |  |  |  |  | 10.6x |
Price / 2020 Earnings per Share |  |  |  | 11.0x |  |  |  |  | 10.6x |
Price / 2021 Earnings per Share |  |  |  | 10.3x |  |  |  |  | 10.3x |

IBKC and First Horizon Selected Companies Analysis. Using publicly available information, KBW compared the financial performance, financial condition and market performance of IBKC and First Horizon to nine publicly-traded banks and thrifts in the Southeast, Texas and Louisiana with total assets between $20.0 billion and $50.0 billion. Merger targets and mutual holding companies were excluded from the selected companies.

The selected companies were as follows:

Bank OZK |  |
BankUnited, Inc. |  |
Cullen/Frost Bankers, Inc. |  |
First Citizens BancShares, Inc. |  |
Hancock Whitney Corporation |  |
Pinnacle Financial Partners, Inc. |  |
Prosperity Bancshares, Inc. |  |
Synovus Financial Corp. |  |
Texas Capital Bancshares, Inc. |  |

To perform this analysis, KBW used profitability and other financial information for the latest 12 months (“LTM”) available or as of the end of the most recent quarter available and market price information as of November 1, 2019. KBW also used 2019, 2020 and 2021 EPS estimates taken from publicly available consensus “street estimates” for IBKC, First Horizon and the eight selected companies for which consensus “street estimates” were available. Certain financial data prepared by KBW, as referenced in the tables presented below, may not correspond to the data presented in IBKC’s or First Horizon’s historical financial statements, or the data prepared by Goldman Sachs presented under the section “The Merger—Opinions of IBKC’s Financial Advisors—Opinion of Goldman Sachs & Co. LLC” or Morgan Stanley presented under the section “The Merger—Opinion of First Horizon’s Financial Advisor,” as a result of the different periods, assumptions and methods used by KBW to compute the financial data presented.

KBW’s analysis showed the following concerning the financial performance of IBKC, First Horizon and the selected companies:

In addition, KBW’s analysis showed the following concerning the market performance of IBKC, First Horizon and, to the extent publicly available, the selected companies:

|  | IBKC |  | First Horizon |  | Selected Companies
| Bottom Quartile |  | Median |  | Average |  | Top Quartile
1—Year Stock Price Change (%) |  | (0.2) |  | (0.5) |  | (8.3) |  | 5.0 |  | 0.9 |  | 7.0

| (1) |  | Consensus “street estimates” for First Citizens BancShares, Inc. were not available for purposes of calculating EPS multiples for the selected companies.
| (2) |  | First EPS multiples were calculated using consensus “street estimates.” Second EPS multiples were calculated using financial forecasts and projections of IBKC or First Horizon, as the case may be, provided by IBKC management.
| (3) |  | First EPS multiples were calculated using consensus “street estimates.” Second EPS multiples were calculated using financial forecasts and projections of First Horizon provided by First Horizon management.

The low and high stock price-to-tangible book value per share multiples of the selected companies were 1.08x and 2.22x, respectively. For the eight selected companies for which consensus “street estimates” were available (which included all of the selected companies other than First Citizens BancShares, Inc.), the low and high stock price-to-2019 estimated EPS multiples of the selected companies were 8.7x and 15.0x, respectively, the low and high stock price-to-2020 estimated EPS

94

multiples of the selected companies were 9.5x and 14.7x, respectively, and the low and high stock price-to-2021 estimated EPS multiples of the selected companies were 8.9x and 14.2x, respectively.

No company used as a comparison in the above selected companies analysis is identical to IBKC or First Horizon. Accordingly, an analysis of these results is not mathematical. Rather, it involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies involved.

Relative Contribution Analysis. KBW analyzed the relative standalone contribution of First Horizon and IBKC to various pro forma balance sheet and income statement items of the combined entity. This analysis did not include purchase accounting adjustments or synergies. To perform this analysis, KBW used (i) historical balance sheet data for First Horizon and IBKC as of September 30, 2019, (ii) publicly available consensus “street estimates” of First Horizon and IBKC, (iii) financial forecasts and projections of First Horizon (with respect to fiscal years 2019 and 2020) provided by First Horizon management, and (iv) financial forecasts and projections of First Horizon (with respect to fiscal year 2021) and IBKC provided by IBKC management. The results of KBW’s analysis are set forth in the following table, which also compares the results of KBW’s analysis with the implied pro forma ownership percentages of First Horizon and IBKC shareholders in the combined company based on the 4.584x exchange ratio in the proposed merger and a diluted IBKC share count as of September 30, 2019 (net of restricted stock awards assumed to be withheld for tax liability purposes) per IBKC management and diluted First Horizon share count as of September 30, 2019 per First Horizon management:

|  | First Horizon as a % of Total |  | IBKC as a % of Total
Fully Diluted Ownership |  |  |  |
At 4.584x Merger Exchange Ratio |  |  |  | 56.9 | % |  |  |  |  | 43.1 | % |
Balance Sheet |  |  |  |
Assets |  |  |  | 57.9 | % |  |  |  |  | 42.1 | % |
Gross Loans Held for Inv. |  |  |  | 56.9 | % |  |  |  |  | 43.1 | % |
Deposits |  |  |  | 56.1 | % |  |  |  |  | 43.9 | % |
Tangible Common Equity |  |  |  | 52.4 | % |  |  |  |  | 47.6 | % |
Income Statement—“Street” Estimates |  |  |  |
2019 Est. GAAP Net Income to Common |  |  |  | 57.4 | % |  |  |  |  | 42.6 | % |
2020 Est. GAAP Net Income to Common |  |  |  | 58.4 | % |  |  |  |  | 41.6 | % |
2021 Est. GAAP Net Income to Common |  |  |  | 58.5 | % |  |  |  |  | 41.5 | % |

2021 Est. GAAP Net Income to Common |  |  |  | 58.6 | % |  |  |  |  | 41.4 | % |

Pro Forma Financial Impact Analysis. KBW performed a pro forma financial impact analysis that combined projected income statement and balance sheet information of First Horizon and IBKC. Using (i) closing balance sheet estimates as of June 30, 2020 for First Horizon and IBKC provided by First Horizon and IBKC managements, (ii) financial forecasts and projections of First Horizon (with respect to fiscal years 2019 and 2020) provided by First Horizon management, (iii) financial forecasts and projections of First Horizon (with respect to fiscal year 2021) and IBKC provided by IBKC management, and (iv) pro forma assumptions (including, without limitation, the cost savings and related expenses expected to result from the merger as well as certain accounting adjustments and restructuring charges assumed with respect thereto) provided by First Horizon management, KBW analyzed the estimated financial impact of the merger on certain projected financial results. This analysis indicated that the merger could be accretive to First Horizon’s 2020 estimated EPS (assuming full year impact) by approximately 8.9%, accretive to First Horizon’s 2021 estimated EPS by approximately 13.6%, and dilutive to First Horizon’s estimated tangible book value per share at closing as of June 30, 2020 by approximately 5.4%. Furthermore, this analysis indicated that, pro

95

forma for the merger, each of First Horizon’s tangible common equity to tangible assets ratio, tier 1 leverage ratio, common equity tier 1 ratio, tier 1 capital ratio and total risk-based capital ratio could be lower at closing as of June 30, 2020. For all of the above analysis, the actual results achieved by First Horizon following the merger may vary from the projected results, and the variations may be material.

IBKC Discounted Cash Flow Analysis. KBW performed a discounted cash flow analysis to estimate a range for the implied equity value of IBKC. In this analysis, KBW utilized financial forecasts and projections relating to the net income and assets of IBKC provided by IBKC management, and assumed discount rates ranging from 9.0% to 11.0%. The range of discount rates assumed in this analysis was selected taking into account a capital asset pricing model implied cost of capital calculation. The range of values was derived by adding (i) the present value of the estimated excess cash flows that IBKC could generate over the 4.5-year period from the second quarter of 2020 through 2024 and (ii) the present value of IBKC’s implied terminal value at the end of such period. KBW assumed that IBKC would maintain a common equity tier 1 ratio of 10.00% and IBKC would retain sufficient earnings to maintain that level. Estimates of excess cash flows were calculated generally as any portion of estimated earnings in excess of the amount assumed to be retained by IBKC to maintain the assumed common equity tier 1 ratio. In calculating the terminal value of IBKC, KBW applied a range of 9.5x to 11.5x IBKC’s estimated 2025 earnings. This discounted cash flow analysis resulted in a range of implied values per share of IBKC common stock of $70.37 per share to $85.85 per share.

The discounted cash flow analysis is a widely used valuation methodology, but the results of such methodology are highly dependent on the assumptions that must be made, including asset and earnings growth rates, terminal values, dividend payout rates, and discount rates. The above analysis did not purport to be indicative of the actual values or expected values of IBKC.

First Horizon Discounted Cash Flow Analysis. KBW performed a discounted cash flow analysis to estimate a range for the implied equity value of First Horizon. In this analysis, KBW used financial forecasts and projections relating to the net income and assets of First Horizon (with respect to fiscal years 2019 and 2020) provided by First Horizon management and financial forecasts and projections relating to the net income and assets of First Horizon (with respect to certain fiscal years beyond 2020) provided by IBKC management, and assumed discount rates ranging from 8.5% to 10.5%. The range of discount rates assumed in this analysis was selected taking into account a capital asset pricing model implied cost of capital calculation. The range of values was derived by adding (i) the present value of the estimated excess cash flows that First Horizon could generate over the 4.5-year period from the second quarter of 2020 through 2024 and (ii) the present value of First Horizon’s implied terminal value at the end of such period. KBW assumed that First Horizon would maintain a common equity tier 1 ratio of 10.00% and First Horizon would retain sufficient earnings to maintain that level. Estimates of excess cash flows were calculated generally as any portion of estimated earnings in excess of the amount assumed to be retained by First Horizon to maintain the assumed common equity tier 1 ratio. In calculating the terminal value of First Horizon, KBW applied a range of 9.5x to 11.5x First Horizon’s estimated 2025 earnings. This discounted cash flow analysis resulted in a range of implied values per share of First Horizon common stock of $15.64 per share to $19.37 per share.

The discounted cash flow analysis is a widely used valuation methodology, but the results of such methodology are highly dependent on the assumptions that must be made, including asset and earnings growth rates, terminal values, dividend payout rates, and discount rates. The above analysis did not purport to be indicative of the actual values or expected values of First Horizon.

Pro Forma Combined Discounted Cash Flow Analysis. KBW performed a discounted cash flow analysis to estimate an illustrative range for the implied equity value of the pro forma combined entity, taking into account the cost savings and related expenses expected to result from the merger as well as certain accounting adjustments and restructuring charges assumed with respect thereto. In this analysis, KBW used financial forecasts and projections relating to the net income and assets of First Horizon (with respect to fiscal years 2019 and 2020) provided by First Horizon management,

96

financial forecasts and projections relating to the net income and assets of First Horizon (with respect to certain fiscal years beyond 2020) and IBKC provided by IBKC management, and estimated cost savings and related expenses and accounting adjustments and restructuring charges provided by First Horizon management, and assumed discount rates ranging from 8.75% to 10.75%. The range of discount rates assumed in this analysis was selected taking into account capital asset pricing model implied cost of capital calculations. The range of values was derived by adding (i) the present value of the estimated excess cash flows that the pro forma combined entity could generate over the 4.5-year period from the second quarter of 2020 through 2024 and (ii) the present value of the pro forma combined entity’s implied terminal value at the end of such period, in each case applying estimated cost savings and related expenses and accounting adjustments and restructuring charges. KBW assumed that the pro forma combined entity would maintain a common equity tier 1 ratio of 10.00% and would retain sufficient earnings to maintain that level. Estimates of excess cash flows were calculated generally as any portion of estimated earnings in excess of the amount assumed to be retained by the pro forma combined entity to maintain the assumed common equity tier 1 ratio. In calculating the terminal value of the pro forma combined entity, KBW applied a range of 9.5x to 11.5x the pro forma combined entity’s estimated 2025 earnings. This discounted cash flow analysis resulted in an illustrative range of implied values of $77.89 to $96.57 for the 4.584 shares of First Horizon common stock to be received in the proposed merger for each share of IBKC common stock.

The discounted cash flow analysis is a widely used valuation methodology, but the results of such methodology are highly dependent on the assumptions that must be made, including asset and earnings growth rates, terminal values, dividend payout rates, and discount rates. The above analysis did not purport to be indicative of the actual values or expected values of the pro forma combined entity.

Miscellaneous. KBW acted as financial advisor to IBKC and not as an advisor to or agent of any other person. As part of its investment banking business, KBW is continually engaged in the valuation of bank and bank holding company securities in connection with acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for various other purposes. As specialists in the securities of banking companies, KBW has experience in, and knowledge of, the valuation of banking enterprises. KBW and its affiliates, in the ordinary course of its and their broker-dealer businesses (and further to existing sales and trading relationships between each of KBW and a KBW broker-dealer affiliate and IBKC), may from time to time purchase securities from, and sell securities to, IBKC and First Horizon. In addition, as a market maker in securities, KBW and its affiliates may from time to time have a long or short position in, and buy or sell, debt or equity securities of IBKC or First Horizon for its and their own respective accounts and for the accounts of its and their respective customers and clients.

Pursuant to the KBW engagement agreement, IBKC agreed to pay KBW a cash fee equal to 0.70% of the aggregate merger consideration, which fee is estimated to be approximately $29 million, based on the closing share price of First Horizon common stock on November 1, 2019, $4,000,000 of which became payable upon IBKC entering into the merger agreement and the balance of which is contingent upon the completion of the merger. IBKC also agreed to reimburse KBW for reasonable out-of-pocket expenses and disbursements incurred in connection with its retention and to indemnify KBW against certain liabilities relating to or arising out of KBW’s engagement or KBW’s role in connection therewith. In addition to the present engagement, in the two years preceding the date of its opinion, KBW provided investment banking or financial advisory services to IBKC and received compensation for such services. KBW acted as financial advisor to IBKC in connection with its March 2018 acquisition of Gibraltar Private Bank & Trust Co. In addition, KBW acted as joint book-running manager for IBKC’s March 2019 offering of preferred stock. In connection with the foregoing acquisition and preferred stock offering, KBW received fees (including underwriting discounts) of approximately $1.2 million in the aggregate from IBKC. During the two years preceding the date of its opinion, KBW did not provide investment banking and financial advisory services to First Horizon. KBW may in the future provide investment banking and financial advisory services to IBKC or First Horizon and receive compensation for such services.

The full text of the written opinion of Goldman Sachs, dated November 3, 2019, which sets forth the assumptions made, procedures followed, matters considered, qualifications and limitations on the review undertaken in connection with the opinion, is attached to this joint proxy statement/prospectus as Annex D. The summary of the Goldman Sachs opinion contained in this joint proxy statement/prospectus is qualified in its entirety by reference to the full text of Goldman Sachs’ written opinion. Goldman Sachs’ advisory services and opinion were provided for the information and assistance of the IBKC board of directors in connection with its consideration of the merger and the opinion does not constitute a recommendation as to how any holder of IBKC common stock should vote with respect to the merger or any other matter.

In connection with rendering the opinion described above and performing its related financial analyses, Goldman Sachs reviewed, among other things:

| • |  | the merger agreement;
| • |  | annual reports to shareholders and Annual Reports on Form 10-K of IBKC and First Horizon for the five (5) years ended December 31, 2018;
| • |  | certain interim reports to shareholders and Quarterly Reports on Form 10-Q of IBKC and First Horizon;
| • |  | certain other communications from IBKC and First Horizon to their respective shareholders;
| • |  | certain publicly available research analyst reports for IBKC and First Horizon;
| • |  | certain internal financial analyses and forecasts for First Horizon on a stand-alone basis prepared by its management; and
| • |  | certain internal financial analyses and forecasts for IBKC on a stand-alone basis prepared by its management and certain financial analyses and forecasts for First Horizon on a stand-alone basis and pro forma for the merger prepared by the management of IBKC (referred to in this section as the “management forecasts”), in each case, as approved for Goldman Sachs’ use by IBKC, including certain operating synergies projected by the management of IBKC and the management of First Horizon to result from the merger, as approved for Goldman Sachs’ use by IBKC (referred to in this section as the “synergies”).

Goldman Sachs also held discussions with members of the senior management of IBKC and the senior management of First Horizon regarding their assessments of the strategic rationale for, and the potential benefits of, the merger, and the past and current business operations, financial condition and future prospects of IBKC and First Horizon; reviewed the reported price and trading activity for IBKC common stock and First Horizon common stock; compared certain financial and stock market information for IBKC and First Horizon with similar information for certain other companies the securities of which are publicly traded; reviewed the financial terms of certain recent business combinations in the banking industry; and performed such other studies and analyses, and considered such other factors, as Goldman Sachs deemed appropriate.

For purposes of rendering its opinion, Goldman Sachs, with the consent of the IBKC board of directors, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, Goldman Sachs, without assuming any responsibility for independent verification thereof. In that regard, Goldman Sachs assumed with the consent of the IBKC board of directors that the management forecasts, including the synergies, were reasonably prepared on a basis reflecting the

98

best currently available estimates and judgments of the management of IBKC. Goldman Sachs did not review individual credit files or make an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or other off-balance-sheet assets and liabilities) of IBKC or First Horizon or any of their respective subsidiaries and Goldman Sachs was not furnished with any such evaluation or appraisal. Goldman Sachs is not an expert in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto, and, accordingly, Goldman Sachs assumed that such allowances for IBKC or First Horizon were, in the aggregate, adequate to cover such losses. Goldman Sachs assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the merger would be obtained without any adverse effect on IBKC or First Horizon or on the expected benefits of the merger in any way meaningful to Goldman Sachs’ analysis. Goldman Sachs assumed that the merger would be consummated on the terms set forth in the merger agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to Goldman Sachs’ analysis.

Goldman Sachs’ opinion did not address the underlying business decision of IBKC to engage in the merger, or the relative merits of the merger as compared to any strategic alternatives that may be available to IBKC; nor did it address any legal, regulatory, tax or accounting matters. Goldman Sachs’ opinion addressed only the fairness from a financial point of view to the holders (other than First Horizon and its affiliates) of IBKC common stock as of November 3, 2019 of the exchange ratio. Goldman Sachs did not express any view on, and its opinion did not address, any other term or aspect of the merger agreement or the merger or any term or aspect of any other agreement or instrument contemplated by the merger agreement or entered into or amended in connection with the merger, including the fairness of the merger to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors, or other constituencies of IBKC; nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of IBKC, or class of such persons, in connection with the merger, whether relative to the exchange ratio or otherwise. Goldman Sachs did not express any opinion as to the prices at which the First Horizon common stock would trade at any time or as to the impact of the merger on the solvency or viability of IBKC or First Horizon or the ability of IBKC or First Horizon to pay their respective obligations when they come due. Goldman Sachs’ opinion was necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to Goldman Sachs as of, November 3, 2019 and Goldman Sachs assumed no responsibility for updating, revising or reaffirming its opinion based on circumstances, developments or events occurring after November 3, 2019. Goldman Sachs’ advisory services and its opinion were provided for the information and assistance of IBKC’s board of directors in connection with its consideration of the merger and Goldman Sachs’ opinion does not constitute a recommendation as to how any holder of IBKC common stock should vote with respect to the merger or any other matter. Goldman Sachs’ opinion was approved by a fairness committee of Goldman Sachs.

Selected Companies Analyses for IBKC

Goldman Sachs reviewed and compared certain financial information for IBKC to corresponding financial information and public market multiples for the nine (9) selected publicly traded companies in the banking industry listed below. Although none of the selected companies is directly comparable to IBKC, the selected companies,based on Goldman Sachs’ professional judgment and experience, all of the publicly traded banking organizations based in the Southeastern United States with assets between $20 billion and $50 billion that, for purposes of analysis, may be considered similar to IBKC.

For each of IBKC and the selected companies, Goldman Sachs calculated and compared such company’s closing price per share as of November 1, 2019 as a multiple of each of such company’s:

| • |  | estimated EPS for calendar years 2019 and 2020; and
| • |  | TBV per share as of its most recently completed fiscal quarter for which TBV per share information was publicly available as of November 1, 2019.

For purposes of its calculations, Goldman Sachs used 2019 and 2020 EPS estimates for IBKC and the selected companies reflecting the most recent median EPS estimates for such companies published by IBES as of November 1, 2019. For IBKC, Goldman Sachs also used the 2019 and 2020 EPS estimates reflected in the management forecasts.

The multiples calculated by Goldman Sachs for the selected companies and multiples calculated by Goldman Sachs for IBKC are as follows:

Illustrative Present Value of Future Stock Price Analysis for IBKC

Goldman Sachs performed an illustrative analysis of the implied present value of the future value of the shares of IBKC common stock on a stand-alone basis.

Goldman Sachs derived a range of theoretical future values per share for the shares of IBKC common stock on a stand-alone basis as of December 31, 2019, 2020 and 2021 by applying illustrative price to EPS multiples of 10.4x and 11.4x to the estimates of the EPS of IBKC on a stand-alone basis for 2020, 2021 and 2022, respectively, based on the management forecasts. By applying a discount rate of 8.0%, reflecting an estimate of IBKC’s cost of equity on a stand-alone basis, Goldman Sachs discounted to present value as of September 30, 2019 both the theoretical future values per share it derived for IBKC on a stand-alone basis and the cumulative estimated dividends to be paid per share of IBKC common stock on a stand-alone basis through the end of the applicable year as reflected in the management forecasts, to yield illustrative present values per share of IBKC common stock on a stand-alone basis ranging from $69.77 to $78.91.

The illustrative price to EPS multiples used in the foregoing analysis were derived by Goldman Sachs using its professional judgement and experience, taking into account the multiples calculated by Goldman Sachs as set forth above under “—Selected Companies Analyses for IBKC.” Goldman Sachs derived the discount rate used in the foregoing analysis by application of the capital asset pricing model (“CAPM”), which requires certain company-specific inputs, including a beta for the company, as well as certain financial metrics for the United States financial markets generally.

Regression Analysis for IBKC

Goldman Sachs performed a regression analysis using the Price/TBV per share multiples for the selected companies calculated by Goldman Sachs as described above under “—Selected Companies Analyses for IBKC” compared to the 2020 estimated return on average tangible common equity (“2020E ROATCE”) for those selected companies using the median estimates for such companies published by IBES as of November 1, 2019 to derive a regression line reflecting a range of Price/TBV per share multiples at a range of 2020E ROATCE for the selected companies. The 2020 ROATCE for those selected companies ranged from 9.9% to 16.7%, with a median of 13.8%. Goldman Sachs observed that the 2020E ROATCE for IBKC, as reflected in the management forecasts, corresponded to an implied Price/TBV per share multiple of 1.5x on the regression line. Goldman Sachs calculated that the closing price for IBKC common stock on November 1, 2019 reflected a multiple of approximately 1.4x the TBV per share as of September 30, 2019 for IBKC, as provided by IBKC management, which implied an 8.3% discount to the implied regression line.

Goldman Sachs applied implied Price/TBV per share multiples ranging from 1.3x (0.2x less than the 2020E ROATCE regression implied Price/TBV per share multiple) to 1.7x (0.2x more than the 2020E ROATCE regression implied Price/TBV per share multiple) to the TBV per share as of September 30, 2019 for IBKC, as provided by IBKC management, to derive a range of regression implied values per share of IBKC common stock on a stand-alone basis. Goldman Sachs applied IBKC’s implied 8.3% trading discount to the implied regression line to derive discounted regression implied values per share of IBKC common stock ranging from $65.10 to $84.42.

Illustrative Discounted Dividend Analyses for IBKC on a Stand-Alone Basis

Using the management forecasts, Goldman Sachs performed an illustrative discounted dividend analysis for IBKC on a stand-alone basis, to derive a range of illustrative present values per share of IBKC common stock on a stand-alone basis.

Using discount rates ranging from 7.0% to 9.0%, reflecting estimates of the cost of equity for IBKC on a stand-alone basis, Goldman Sachs derived a range of illustrative equity values for IBKC on a stand-alone basis by discounting to present value as of September 30, 2019, (a) the implied distributions to holders of IBKC common stock over the period beginning September 30, 2019 through December 31, 2024 calculated based on the management forecasts assuming, at the direction

102

of IBKC management, that IBKC would make distributions of capital in excess of the amount necessary to achieve a 10.0% CET1 ratio target and (b) a range of illustrative terminal values for IBKC as of December 31, 2024, calculated by applying illustrative price to EPS multiples ranging from 10.4x to 11.4x (reflecting implied Price/TBV per share exit multiples ranging from 1.4x to 1.6x) to the estimate of IBKC’s terminal year (2025) net income on a stand-alone basis of $420 million, as reflected in the management forecasts. Goldman Sachs derived the range of discount rates by application of the CAPM. To derive illustrative terminal values for IBKC, Goldman Sachs applied illustrative price to EPS multiples based on its professional judgment and experience, taking into account the multiples it calculated as described above under “—Selected Companies Analyses for IBKC.”

Goldman Sachs divided the range of illustrative equity values it derived for IBKC by the total number of fully diluted shares of IBKC common stock outstanding as of September 30, 2019 of 52.3 million, as provided by IBKC management, to derive illustrative present values per share of IBKC common stock on a stand-alone basis ranging from $77.35 to $89.45.

Selected Companies Analyses for First Horizon on a Stand-Alone Basis

Goldman Sachs reviewed and compared certain financial information for First Horizon on a stand-alone basis to corresponding financial information and public market multiples for the nine (9) selected publicly traded companies in the banking industry set forth above under “—Selected Companies Analyses for IBKC.” Although none of the selected companies is directly comparable to First Horizon, the selected companies were chosen because they are publicly traded companies with operations that, for purposes of analysis, may be considered similar to certain operations of First Horizon.

For each of First Horizon on a stand-alone basis and the selected companies, Goldman Sachs calculated and compared such company’s closing price per share as of November 1, 2019 as a multiple of each of such company’s:

| • |  | estimated EPS for the calendar years 2019 and 2020; and
| • |  | TBV per share as of its most recently completed fiscal quarter for which TBV per share information was publicly available as of November 1, 2019.

For purposes of its calculations, Goldman Sachs used 2019 and 2020 EPS estimates for First Horizon on a stand-alone basis and for the selected companies reflecting the most recent median EPS estimates for such companies published by IBES as of November 1, 2019. For First Horizon on a stand-alone basis, Goldman Sachs also used the 2019 and 2020 EPS estimates reflected in the management forecasts.

The multiples calculated by Goldman Sachs for the selected companies are set forth above under “—Selected Companies Analyses for IBKC.” The multiples calculated by Goldman Sachs for First Horizon on a stand-alone basis are as follows:

First Horizon |  | Price/ 2019E EPS |  | Price/ 2020E EPS |  | Price/TBV per share
Management Forecasts/Public Information |  |  |  | 10.1x |  |  |  |  | 10.1x |  |  |  |  | 1.7x |
IBES Median EPS Estimates/Public Information |  |  |  | 10.1x |  |  |  |  | 10.2x |  |  |  |  | 1.7x |

Illustrative Present Value of Future Stock Price Analysis for First Horizon on a Stand-Alone Basis

Goldman Sachs performed an illustrative analysis of the implied present value of the future value of the shares of First Horizon common stock on a stand-alone basis.

Goldman Sachs derived a range of theoretical future values per share for the shares of First Horizon common stock on a stand-alone basis as of December 31, 2019, 2020 and 2021 by applying illustrative price to EPS multiples of 9.7x to 10.7x to the estimates of the EPS of First Horizon on a stand-alone basis for 2020, 2021 and 2022, respectively, based on management forecasts. By applying

103

a discount rate of 7.5%, reflecting an estimate of First Horizon’s cost of equity on a stand-alone basis, Goldman Sachs discounted to present value as of September 30, 2019 both the theoretical future values per share it derived for First Horizon on a stand-alone basis and the cumulative estimated dividends to be paid per share of First Horizon common stock on a stand-alone basis through the end of the applicable year as reflected in the management forecasts, to yield illustrative present values per share of First Horizon common stock on a stand-alone basis ranging from $15.16 to $17.07.

The illustrative price to EPS multiples used in the foregoing analysis were derived by Goldman Sachs based on its professional judgement and experience, taking into account the multiples calculated by Goldman Sachs as set forth above under “—Selected Companies Analyses for IBKC.” Goldman Sachs derived the discount rate used in the foregoing analysis by application of CAPM.

Regression Analysis for First Horizon on a Stand-Alone Basis

Goldman Sachs observed that the 2020E ROATCE for First Horizon on a stand-alone basis, as reflected in the management forecasts, corresponded to an implied Price/TBV per share multiple of 2.1x on the regression line derived by Goldman Sachs reflecting a range of Price/TBV per share multiples at a range of 2020E ROATCEs for the selected companies as described above under “—Regression Analysis for IBKC.” Goldman Sachs calculated that the closing price for First Horizon common stock on November 1, 2019 reflected a multiple of approximately 1.7x the TBV per share as of September 30, 2019 for First Horizon, as provided by First Horizon management, which implied a 19.7% discount to the implied regression line.

Goldman Sachs applied implied Price/TBV per share multiples ranging from 1.9x (0.2x less than the 2020E ROATCE regression implied stand-alone Price/TBV per share multiple) to 2.3x (0.2x more than the 2020E ROATCE implied market stand-alone Price/TBV per share multiple) to the TBV per share as of September 30, 2019 for First Horizon on a stand-alone basis, as provided by First Horizon management, to derive a range of regression implied values per share of First Horizon common stock on a stand-alone basis. Goldman Sachs applied First Horizon’s implied 19.7% trading discount to the implied regression line to derive discounted regression implied values per share of First Horizon common stock ranging from $14.74 to $17.88.

Illustrative Discounted Dividend Analyses for First Horizon on a Stand-Alone Basis

Using the management forecasts, Goldman Sachs performed illustrative discounted dividend analyses for First Horizon on a stand-alone basis, to derive a range of illustrative present values per share of First Horizon common stock on a stand-alone basis.

Using discount rates ranging from 6.5% to 8.5%, reflecting estimates of the cost of equity for First Horizon on a stand-alone basis, Goldman Sachs derived a range of illustrative equity values for First Horizon on a stand-alone basis by discounting to present value as of September 30, 2019, (a) the implied distributions to holders of First Horizon common stock on a stand-alone basis over the period beginning September 30, 2019 through December 31, 2024, on a stand-alone basis, calculated based on the management forecasts assuming at the direction of IBKC management that First Horizon would make distributions of capital in excess of the amount necessary to achieve a 10.0% CET1 ratio target and (b) a range of illustrative terminal values for First Horizon on a stand-alone basis as of December 31, 2024, calculated by applying illustrative price to EPS multiples ranging from 9.7x to 10.7x (reflecting implied price/TBV per share exit multiples ranging from 1.4x to 1.6x) to the estimate of First Horizon’s terminal year (2025) net income on a stand-alone basis of $592 million, as reflected in the management forecasts. Goldman Sachs derived the range of discount rates by application of the CAPM. To derive illustrative terminal values for First Horizon on a stand-alone basis, Goldman Sachs applied illustrative price to EPS multiples based on its professional judgment and experience, taking into account the multiples it calculated for the selected companies as described above under “—Selected Companies Analyses for IBKC” and the multiples

104

it calculated for First Horizon on a stand-alone basis as set forth above under “—Selected Companies Analyses for First Horizon on a Stand-Alone Basis.”

Goldman Sachs divided the range of illustrative equity values it derived for First Horizon on a stand-alone basis by the total number of fully diluted shares of First Horizon common stock outstanding as of September 30, 2019 of 312.0 million, as provided by First Horizon management, to derive illustrative present values per share of First Horizon common stock on a stand-alone basis ranging from $16.02 to $18.83.

Illustrative Present Value of Future Stock Price Analyses for IBKC Shares on a Pro Forma Basis

Goldman Sachs performed an illustrative analysis of the implied present value of the future value of the 4.584 shares of First Horizon common stock to be received for each share of IBKC common stock in the merger.

Goldman Sachs derived a range of theoretical future values per share for the shares of First Horizon common stock on a pro forma basis (giving effect to the merger) as of December 31, 2020, 2021 and 2022 by applying illustrative price to EPS multiples of 10.0x to 11.0x to the estimates of the EPS of First Horizon on a pro forma basis for 2021, 2022 and 2023, respectively, based on the management forecasts, taking into account the synergies. By applying a discount rate of 7.75%, reflecting an estimate of First Horizon’s cost of equity on a pro forma basis (based on the estimated cost of equity for each of First Horizon and IBKC on a stand-alone basis blended based on the pro forma ownership of their respective common shareholders in the combined company), Goldman Sachs discounted to present value as of September 30, 2019 both the theoretical future values per share it derived for First Horizon on a pro forma basis and the cumulative estimated dividends to be paid per share of First Horizon common stock on a stand-alone basis until the estimated transaction closing and a pro forma basis thereafter through the end of the applicable year as reflected in the management forecasts to yield illustrative present values per share of First Horizon common stock on a pro forma basis. Goldman Sachs then multiplied this range by the exchange ratio to yield illustrative present values ranging from $81.23 to $92.16 for the 4.584 shares of First Horizon common stock to be received for each share of IBKC common stock in the merger. The illustrative price to EPS multiples used in the foregoing analysis were derived by Goldman Sachs based on its professional judgment and experience, taking into account the multiples calculated by Goldman Sachs as set forth above under “—Selected Companies Analyses for IBKC.”

Regression Analysis for IBKC Shares on a Pro Forma Basis

Goldman Sachs observed that the estimated 2020E ROATCE for First Horizon on a pro forma basis, as reflected in the management forecasts, corresponded to an implied Price/TBV per share multiple of 2.7x on the regression line derived by Goldman Sachs reflecting a range of Price/TBV per share multiples at a range of 2020E ROATCEs for the selected companies as described above under “—Regression Analysis for IBKC.”

Goldman Sachs applied implied Price/TBV per share multiples ranging from 2.5x (0.2x less than the 2020E ROATCE regression implied pro forma Price/TBV per share multiple) to 2.9x (0.2x more than the 2020E ROATCE implied market pro forma Price/TBV per share multiple) to the TBV per share as of June 30, 2020 for First Horizon on a pro forma basis as reflected in the management forecasts, and discounting the results to present value as of September 30, 2019, using a discount rate of 7.75%, reflecting an estimate of First Horizon’s cost of equity on a pro forma basis (based on the estimated cost of equity for each of First Horizon and IBKC on a stand-alone basis blended based on the pro forma ownership of their respective common shareholders in the combined company), to derive a range of regression implied present values per share of First Horizon common stock on a pro forma basis. Goldman Sachs then applied a discount of 14.8%, which was calculated to be IBKC’s and First Horizon’s blended current trading discount to the implied regression line based on the pro forma ownership of their respective common shareholders in the combined company, to derive a range of discounted regression implied present values per share of First

105

Horizon common stock on a pro forma basis. Goldman Sachs multiplied this range by the exchange ratio to derive discounted regression implied present values ranging from $88.13 to $102.38 for the 4.584 shares of First Horizon common stock to be received for each share of IBKC common stock in the merger.

Illustrative Discounted Dividend Analyses for IBKC Shares on a Pro Forma Basis

Using the management forecasts, Goldman Sachs performed illustrative discounted dividend analysis for First Horizon on a pro forma basis giving effect to the merger. Using discount rates ranging from 6.75% to 8.75%, reflecting estimates of the cost of equity for First Horizon on a pro forma basis giving effect to the merger, Goldman Sachs derived a range of illustrative equity values for First Horizon on a pro forma basis by discounting to present value as of September 30, 2019, (a) the implied distributions to/ infusions from holders of First Horizon’s common stock on a pro forma basis from June 30, 2020 through December 31, 2024 calculated using the management forecasts, taking into account the synergies, assuming, at the direction of IBKC management, that First Horizon would on a pro forma basis make distributions/require infusions of capital as necessary to achieve a 10.0% CET1 ratio target and (b) a range of illustrative terminal values for First Horizon on a pro forma basis as of December 31, 2024, calculated by applying illustrative price to EPS multiples ranging from 10.0x to 11.0x (reflecting implied price/TBV per share multiples ranging from 1.7x to 1.9x) to the estimate of First Horizon’s terminal year (2025) net income on a pro forma basis of $1,193 million, as reflected in the management forecasts, taking into account the synergies. To derive illustrative terminal values for First Horizon on a pro forma basis, Goldman Sachs applied illustrative price to EPS multiples based on its professional judgment and experience, the multiples it calculated for the selected companies and IBKC on a stand-alone basis as described above under “—Selected Companies Analyses for IBKC” and the multiples it calculated for First Horizon on a stand-alone basis as set forth above under “—Selected Companies Analyses for First Horizon on a Stand-Alone Basis.”

Goldman Sachs divided the range of illustrative equity values it derived for First Horizon on a pro forma basis by the total number of fully diluted shares of First Horizon common stock outstanding of 312.0 million, as provided by First Horizon management, increased by 239.9 million, the number of shares of First Horizon common stock anticipated to be issued in the merger, as provided by IBKC management, to derive a range of illustrative present values per share of First Horizon common stock on a pro forma basis. Goldman Sachs then multiplied this range by the exchange ratio, to derive illustrative present values ranging from $82.71 to $97.56 for the 4.584 shares of First Horizon common stock to be received for each share of IBKC common stock in the merger.

Illustrative Contribution Analysis

Using the management forecasts and publicly available information, Goldman Sachs analyzed the implied equity contributions of First Horizon and IBKC to the pro forma combined company based on specific historical and estimated future operating and financial information of each company, including, among other things, closing stock prices of each company as of November 1, 2019, average closing stock prices of each company for the six (6)-month, one (1)-year, three (3)-year and five (5)-year periods ended November 1, 2019, actual net income for 2018, and estimated net income for 2019 through 2020.

Based on the number of fully diluted shares of First Horizon common stock and IBKC common stock outstanding as of November 1, 2019, as provided by IBKC management, following the consummation of the merger, holders of IBKC common stock would hold approximately 43.1% of the fully diluted shares of the pro forma combined company, and holders of First Horizon common

106

stock would hold approximately 56.9% of the fully diluted shares of the pro forma combined company. The following table presents the results of this analysis:

|  | IBKC |  | First Horizon
Closing Share Prices |  |  |  |
November 1, 2019 |  |  |  | 43.1 | % |  |  |  |  | 56.9 | % |
6-Month Average |  |  |  | 44.0 | % |  |  |  |  | 56.0 | % |

General

The preparation of a fairness opinion is a complex process and is not necessarily susceptible to partial analysis or summary description. Selecting portions of the analyses or of the summary set forth above, without considering the analyses as a whole, could create an incomplete view of the processes underlying Goldman Sachs’ opinion. In arriving at its fairness determination, Goldman Sachs considered the results of all of its analyses and did not attribute any particular weight to any factor or analysis considered by it. Rather, Goldman Sachs made its determination as to fairness on the basis of its experience and professional judgment after considering the results of all of its analyses. No company used in the above analyses as a comparison is directly comparable to IBKC or First Horizon.

Goldman Sachs prepared these analyses for purposes of providing its opinion to the IBKC board of directors that, as of the date of the opinion, the exchange ratio was fair from a financial point of view to the holders (other than First Horizon and its affiliates) of IBKC common stock. These analyses do not purport to be appraisals nor do they necessarily reflect the prices at which businesses or securities actually may be sold. Analyses based upon projections of future results are not necessarily indicative of actual future results, which may be significantly more or less favorable than suggested by these analyses. Because these analyses are inherently subject to uncertainty, being based upon numerous factors or events beyond the control of the parties or their respective advisors, Goldman Sachs does not assume responsibility if future results are materially different from those forecast.

The exchange ratio and the merger consideration to be paid by First Horizon for each share of IBKC common stock pursuant to the merger agreement was determined through arm’s-length negotiations between IBKC and First Horizon and was approved by the IBKC board of directors. Goldman Sachs provided advice to IBKC during these negotiations. Goldman Sachs did not, however, recommend any specific exchange ratio or amount of consideration to IBKC or that any specific exchange ratio or amount of consideration constituted the only appropriate consideration for the merger.

As described above, Goldman Sachs’ opinion was one of many factors taken into consideration by the IBKC board of directors in making its determination to approve the merger. The foregoing summary does not purport to be a complete description of the analyses performed by Goldman Sachs in connection with the delivery of its fairness opinion to the IBKC board of directors and is qualified in its entirety by reference to the written opinion of Goldman Sachs attached as Annex D to this joint proxy statement/prospectus.

Goldman Sachs and its affiliates are engaged in advisory, underwriting and financing, principal investing, sales and trading, research, investment management and other financial and non-financial activities and services for various persons and entities. Goldman Sachs and its affiliates and

107

employees, and funds or other entities they manage or in which they invest or have other economic interests or with which they co-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of IBKC, First Horizon, any of their respective affiliates and third parties, or any currency or commodity that may be involved in the merger. Goldman Sachs acted as financial advisor to IBKC in connection with, and participated in certain of the negotiations leading to, the merger. Goldman Sachs expects to receive fees from IBKC for its services in connection with the merger, the principal portion of which is contingent upon consummation of the merger, and IBKC has agreed to reimburse certain of Goldman Sachs’ expenses arising, and indemnify Goldman Sachs against certain liabilities that may arise, out of its engagement. Goldman Sachs may in the future provide financial advisory and/or underwriting services to IBKC, First Horizon and their respective affiliates for which its Investment Banking Division may receive compensation.

IBKC selected Goldman Sachs as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the merger. Pursuant to an engagement letter dated October 29, 2019, Goldman Sachs was engaged to serve as the financial advisor to the IBKC board of directors in connection with the merger. The engagement letter between IBKC and Goldman Sachs provides for a fee that is estimated to be approximately $19.6 million, based on the closing share price of First Horizon common stock on November 1, 2019. $2.5 million of Goldman Sachs’ fee became payable upon the execution of the merger agreement and the remainder of Goldman Sachs’ fee will become payable upon completion of the merger. In addition, IBKC agreed to reimburse Goldman Sachs for certain of its expenses, including reasonable attorneys’ fees and disbursements, and to indemnify Goldman Sachs and related persons against various liabilities, including certain liabilities under the federal securities laws. During the two year period ended November 3, 2019, the Investment Banking Division of Goldman Sachs has not been engaged by IBKC or First Horizon or any of their respective affiliates to provide financial advisory or underwriting services for which Goldman Sachs has recognized compensation.

Unaudited Financial Forecasts

First Horizon and IBKC do not, as a matter of course, publicly disclose forecasts or internal projections as to future performance, revenues, earnings, financial condition or other results due to, among other reasons, the inherent uncertainty of the underlying assumptions and estimates.

However, in connection with the merger, First Horizon senior management prepared or approved for use certain unaudited prospective financial information with respect to First Horizon on a standalone basis and without giving effect to the merger for calendar years 2019 and 2020 (the “First Horizon financial forecasts”). The First Horizon financial forecasts were provided to IBKC and IBKC’s financial advisors. In addition, IBKC senior management prepared or approved for use certain unaudited prospective financial information (i) with respect to IBKC for calendar years 2019 through 2024, (ii) with respect to First Horizon by making certain adjustments and including certain additional line items to the First Horizon financial forecasts for calendars year 2019 and 2020, and (iii) with respect to First Horizon for calendar years 2021 through 2024, in each case on a standalone basis and without giving effect to the merger (the “IBKC financial forecasts”). The IBKC financial forecasts were provided to and used by KBW and Goldman Sachs for the purpose of performing financial analyses in connection with their respective opinions, as described in this joint proxy statement/prospectus under the heading “—Opinions of IBKC’s Financial Advisors” beginning on page 88. First Horizon senior management also approved for use certain publicly available consensus “street estimates” for First Horizon and IBKC, as extrapolated for certain fiscal years based on the guidance of First Horizon senior management, which were provided to and used by Morgan Stanley for the purpose of performing its financial analysis in connection with its opinion, as described in this joint proxy statement/prospectus under the heading “—Opinion of First Horizon’s Financial Advisor” beginning on page 79 (the “consensus ‘street estimates’”). In addition, (1) the IBKC financial forecasts were provided to First Horizon and to the IBKC board of directors and (2) the First Horizon financial forecasts were provided to IBKC, in each case in connection with their

108

respective evaluations of the merger. The IBKC financial forecasts, the First Horizon financial forecasts and the consensus “street estimates” are collectively referred to in this joint proxy statement/prospectus as the “financial forecasts.”

The financial forecasts were not prepared for the purposes of, or with a view toward, public disclosure (except in the case of the publicly available consensus “street estimates,” excluding, for the avoidance of doubt, the extrapolations included in the consensus “street estimates”) or with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants for preparation and presentation of prospective financial information, published guidelines of the SEC regarding forward-looking statements or generally accepted accounting principles. A summary of certain significant elements of this information is set forth below, and is included in this joint proxy statement/prospectus solely for the purpose of providing First Horizon shareholders and IBKC shareholders access to certain prospective financial information made available to IBKC’s financial advisors for the purpose of performing financial analyses in connection with their respective opinions. The information included below does not comprise all of the prospective financial information provided to IBKC’s financial advisors.

Although presented with numeric specificity, the IBKC financial forecasts reflect numerous estimates and assumptions made by IBKC senior management at the time such forecasts were prepared, or approved for use by IBKC’s financial advisors, and represent IBKC senior management’s evaluation of IBKC’s and First Horizon’s expected future financial performance on a stand-alone basis, without reference to the merger. Similarly, the First Horizon financial forecasts reflect numerous estimates and assumptions made by First Horizon senior management at the time such forecasts were prepared, or approved for use by IBKC’s financial advisors, and represent First Horizon senior management’s evaluation of First Horizon’s expected future financial performance on a stand-alone basis, without reference to the merger. In addition, the extrapolations included in the consensus “street estimates” reflect numerous estimates and assumptions made by First Horizon senior management at the time such forecasts were confirmed for use by First Horizon’s financial advisor and represent IBKC senior management’s and First Horizon senior management’s respective evaluations of IBKC’s and First Horizon’s expected future financial performance on a stand-alone basis, without reference to the merger. These and the other estimates and assumptions underlying the financial forecasts involve judgments with respect to, among other things, economic, competitive, regulatory and financial market conditions and future business decisions that may not be realized and that are inherently subject to significant business, economic, competitive and regulatory uncertainties and contingencies, including, among other things, the inherent uncertainty of the business and economic conditions affecting the industries in which IBKC and First Horizon operate and the risks and uncertainties described under “Risk Factors” beginning on page 41, “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 39 and in the reports that IBKC and First Horizon respectively file with the SEC from time to time, all of which are difficult to predict and many of which are outside the control of IBKC and First Horizon and will be beyond the control of the combined company following completion of the merger. There can be no assurance that the underlying assumptions would prove to be accurate or that the projected results would be realized, and actual results could differ materially from those reflected in the financial forecasts, whether or not the merger is completed. Further, these assumptions do not include all potential actions that the senior management of IBKC or First Horizon could or might have taken during these time periods. The inclusion in this joint proxy statement/prospectus of the unaudited prospective financial information below should not be regarded as an indication that First Horizon, IBKC or their board of directors or financial advisors, considered, or now consider, these projections and forecasts to be material information to any First Horizon shareholder or IBKC shareholder, as the case may be, particularly in light of the inherent risks and uncertainties associated with those projections and forecasts. The financial forecasts are not fact and should not be relied upon as being necessarily indicative of actual future results, and this information should not be relied on as such. The financial forecasts also reflect numerous variables, expectations and assumptions available at the time they were prepared as to certain business decisions that are subject to change and do not take into account any circumstances or events occurring after the date they were prepared. No assurances can be given that if these financial forecasts and the underlying assumptions had been prepared as

109

of the date of this joint proxy statement/prospectus, similar assumptions would be used. In addition, the financial forecasts may not reflect the manner in which the combined company would operate after the merger.

Ernst & Young LLP (IBKC’s independent registered public accounting firm) and KPMG LLP (First Horizon’s independent registered public accounting firm) have not examined, compiled or otherwise performed any procedures with respect to the prospective financial information contained in these financial forecasts and, accordingly, neither Ernst & Young LLP nor KPMG LLP have expressed any opinion or given any other form of assurance with respect thereto and they assume no responsibility for the prospective financial information. The reports of the independent registered public accounting firms incorporated by reference in this joint proxy statement/prospectus relate to the historical financial information of IBKC and First Horizon, as applicable. Such reports do not extend to the financial forecasts and should not be read to do so. No independent registered public accounting firm has examined, compiled or otherwise performed any procedures with respect to the prospective financial information contained in these financial forecasts and, accordingly, no independent registered public accounting firm has expressed any opinion or given any other form of assurance with respect thereto and no independent registered public accounting firm assumes any responsibility for the prospective financial information.

In light of the foregoing, and taking into account that the First Horizon special meeting and the IBKC special meeting will be held several months after the financial forecasts were prepared, as well as the uncertainties inherent in any forecasted information, First Horizon shareholders and IBKC shareholders are strongly cautioned not to place unwarranted reliance on such information, and First Horizon and IBKC urge all First Horizon shareholders and IBKC shareholders to review First Horizon’s and IBKC’s respective most recent SEC filings for descriptions of First Horizon’s and IBKC’s respective reported financial results. See “Where You Can Find More Information” in the forepart of this joint proxy statement/prospectus.

General

The financial forecasts were prepared separately using, in some cases, different assumptions, and are not intended to be added together. Adding the financial forecasts together for the two companies is not intended to represent the results the combined company will achieve if the merger is completed and is not intended to represent forecasted financial information for the combined company if the merger is completed.

By including in this joint proxy statement/prospectus a summary of the financial forecasts, neither First Horizon nor IBKC nor any of IBKC’s representatives has made or makes any representation to any person regarding the ultimate performance of First Horizon or IBKC compared to the information contained in the financial forecasts. Neither First Horizon, IBKC nor, after completion of the merger, the combined company undertakes any obligation to update or otherwise revise the financial forecasts or financial information to reflect circumstances existing since their preparation or to reflect the occurrence of subsequent or unanticipated events, even in the event that any or all of the underlying assumptions are shown to be in error, or to reflect changes in general economic or industry conditions.

The financial forecasts summarized in this section are not being included in this joint proxy statement/prospectus in order to induce any First Horizon shareholder to vote in favor of the First Horizon merger proposal or any of the other proposals to be voted on at the First Horizon special meeting or to induce any IBKC shareholder to vote in favor of the IBKC merger proposal or any of the other proposals to be voted on at the IBKC special meeting.

Consensus “Street Estimates”

First Horizon senior management confirmed that Morgan Stanley should use the following publicly available consensus “street estimates” for First Horizon, as extrapolated for certain fiscal years based on the guidance of First Horizon senior management: (1) 2019, 2020 and 2021 earnings per share of $1.61 per share, $1.61 per share and $1.68 per share, respectively, and (2) 2019, 2020 and 2021 net

112

income of $488 million, $498 million and $508 million, respectively, which First Horizon advised were consistent with First Horizon’s internal estimates. First Horizon senior management confirmed that Morgan Stanley should use the following publicly available consensus “street estimates” for IBKC, as extrapolated for certain fiscal years based on the guidance of First Horizon senior management: (1) 2019, 2020 and 2021 earnings per share of $7.11 per share, $6.84 per share and $7.31 per share, respectively, and (2) 2019, 2020 and 2021 net income of $371 million, $354 million and $362 million, respectively, which IBKC advised were consistent with IBKC’s internal estimates. In addition, First Horizon confirmed that Morgan Stanley should use an estimated 5.0% net income growth rate for each of First Horizon and IBKC for 2022, 2023 and 2024.

Interests of Certain First Horizon Directors and Executive Officers in the Merger

In considering the recommendation of the First Horizon board of directors to vote to approve the First Horizon merger proposal, holders of First Horizon common stock should be aware that the directors and executive officers of First Horizon may have interests in the merger that are different from, or in addition to, the interests of holders of First Horizon common stock generally and that may create potential conflicts of interest. The First Horizon board of directors was aware of these interests and considered them, among other matters, in evaluating and negotiating the merger agreement and approving the merger agreement, and in recommending to holders of First Horizon common stock that they vote to approve the First Horizon merger proposal. For more information, see the sections entitled “The Merger—Background of the Merger” beginning on page 66 and “The Merger—First Horizon’s Reasons for the Merger; Recommendation of First Horizon’s Board of Directors” beginning on page 73. Any such interests are described in more detail below. Note that the merger will not constitute a change in control for purposes of the First Horizon equity compensation awards held by employees, including those awards held by First Horizon’s executive officers, but will constitute a change in control for the purposes of the Change in Control Severance Agreements between First Horizon and certain of its employees, including its executive officers.

Treatment of First Horizon Equity Awards

The First Horizon stock options, First Horizon restricted stock awards, First Horizon restricted stock units, First Horizon performance stock units and First Horizon deferred stock units (collectively, the “First Horizon equity awards”) held by First Horizon’s directors and executive officers immediately prior to the effective time will not be impacted by the merger and will continue to be awards in respect of First Horizon common stock following the effective time, subject to the same terms and conditions that were applicable to such awards before the effective time. The closing will not constitute a change in control for purposes of the First Horizon equity awards held by First Horizon’s employees, including those held by First Horizon’s directors and executive officers. As such, the merger will not result in First Horizon’s directors and executive officers receiving any enhanced, accelerated or additional vesting or other entitlements with respect to their First Horizon equity awards, except as provided for in connection with certain terminations of employment under the Change in Control Severance Agreements with certain of First Horizon’s executive officers. For more information, see the section entitled “—Change in Control Severance Agreements” beginning on page 115.

Letter Agreement between First Horizon and Mr. Jordan

On November 3, 2019, D. Bryan Jordan, the Chairman, President and Chief Executive Officer of First Horizon, entered into a letter agreement with First Horizon (the “Jordan letter agreement”), providing for the terms of Mr. Jordan’s employment following the closing and supplementing the Jordan CIC agreement. In the event that Mr. Jordan’s employment terminates for any reason prior to the closing or the merger agreement is terminated prior to closing, the Jordan letter agreement will automatically terminate and be of no further force or effect. The Jordan letter agreement provides for the following:

| • |  | As further described in the section entitled “The Merger—Governance of the Combined Company After the Merger” beginning on page 129, on the closing date, Mr. Jordan will

113

|  |  | resign as Chairman, he will continue to serve as President and Chief Executive Officer of the combined company and the combined bank, and Mr. Byrd will be appointed as Executive Chairman of the combined company and the combined bank. During Mr. Jordan’s service as President and Chief Executive Officer of the combined company and the combined bank, Mr. Jordan will continue to be nominated to the board of directors of the combined company and serve on the board of directors of the combined bank.
| • |  | On the chairman succession date (as such term is defined under “The Merger—Interests of Certain IBKC Directors and Executive Officers in the Merger—Chairman Letter Agreement of Mr. Byrd” beginning on page 121), Mr. Jordan will be reappointed Chairman of the combined company and the combined bank, and Mr. Byrd will resign as Executive Chairman of the combined company and the combined bank and become a special adviser to Mr. Jordan.
| • |  | Mr. Jordan will continue to maintain all rights under the Jordan CIC agreement, which will continue in effect for a period of thirty-six (36) months following the closing date. Pursuant to the Jordan letter agreement, the parties acknowledge that the merger constitutes a “change in control” for purposes of the Jordan CIC agreement and upon a termination (i) by First Horizon other than for “cause,” disability or retirement or (ii) by Mr. Jordan for “good reason” during the thirty-six (36)-month period following the closing, Mr. Jordan will be entitled to receive the severance, accelerated vesting of all unvested and outstanding equity awards and other benefits provided under the Jordan CIC agreement, subject to the terms and conditions of the Jordan CIC agreement. In addition, Mr. Jordan will continue to be eligible for insurance coverage under the First Horizon directors’ and officers’ liability insurance policy on substantially the same terms as such coverage is provided to First Horizon’s other directors and executive officers.
| • |  | Mr. Jordan waived his right to terminate his employment for “good reason” under the Jordan CIC agreement solely as a result of Mr. Jordan’s resignation as Chairman of the combined company and the combined bank on the closing date (or the assignment to Mr. Byrd of the certain duties outlined in a separate letter agreement between Mr. Byrd and First Horizon, as described further under “The Merger—Interests of Certain IBKC Directors and Executive Officers in the Merger” beginning on page 119).
| • |  | For purposes of the Jordan CIC agreement, the definition of “good reason” was amended to include (i) any changes in Mr. Jordan’s titles or positions from those contemplated in the Jordan letter agreement or (ii) the failure of First Horizon to reappoint Mr. Jordan as the Chairman of the combined company or of the combined bank on the chairman succession date.

Letter Agreements between First Horizon and Certain of its Executive Officers

Each of Messrs. Losch and Popwell and one (1) additional executive officer who is not a named executive officer have entered into executive letter agreements with First Horizon, which provide for the grant of closing incentive restricted stock awards (the “closing incentive awards”) in consideration for a waiver of the executive’s rights to terminate employment for “good reason” under the executive’s Change in Control Severance Agreement with First Horizon as a result of the executive’s new role at the combined company and any corresponding change in duties and responsibilities. The executive letter agreements also set forth the executive officer’s new position, reporting relationship and principal work location with the combined company.

The closing incentive awards will vest in full on the first (1 st) anniversary of the closing date, subject to the executive officer’s continued employment through such date, and will be forfeited upon any termination of employment other than a termination of the executive officer’s employment by the combined company or combined bank that is not for “cause.” All closing incentive awards also will be forfeited if the merger does not close and will be subject to repayment and recovery in full if the executive materially violates the restrictive covenants contained in the executive letter agreements.

114

Under the executive letter agreements, Messrs. Losch and Popwell and the executive officer who is not a named executive officer have agreed to be bound by certain restrictive covenants, including non-solicitation covenants, for the one-year period following the closing date. Each will also be subject to indefinite non-disparagement and confidentiality covenants.

The amounts of the closing incentive awards are $1,250,000 for Mr. Losch, $1,400,000 for Mr. Popwell and $863,000 for the executive officer who is not a named executive officer. The number of shares for each award was determined using the volume weighted average price of a share of First Horizon common stock over the ten trading days immediately prior to November 18, 2019.

Retention Program

In connection with the merger, First Horizon intends to establish a retention program to promote retention and to incentivize efforts to consummate the merger and effectuate the integration and conversion. Awards under this retention program will be in the form of cash or full-value equity awards that will vest on the first anniversary of the closing date, subject to continued employment through such date; provided that such awards will vest or be payable (as applicable) upon a qualifying termination of employment. First Horizon’s executive officers (including certain of First Horizon’s named executive officers), other than Mr. Jordan and the officers who entered into the executive letter agreements described above, will be eligible to participate in this retention program.

Change in Control Severance Agreements

Each of First Horizon’s executive officers, including each of the named executive officers, is party to a Change in Control Severance Agreement with First Horizon (the “CIC agreements”), which provide for the following benefits if the executive officer’s employment is terminated (i) by First Horizon other than for “cause,” disability or retirement or (ii) by the executive for “good reason,” in each case within thirty-six (36) months of a change in control of First Horizon, such as the merger:

| • |  | the executive’s base salary through the executive’s date of termination at the rate in effect just prior to the time a notice of termination is given, plus any bonus amounts which have become earned and payable but have not yet been paid, plus the value of the executive’s accrued but unused vacation days;
| • |  | a pro rata portion of the executive officer’s annual bonus, based on the product of (i) the executive’s bonus amount (which is average of the annual bonuses received for the five (5) fiscal years prior to the date of termination after excluding the highest and lowest of such full-year annual bonuses; provided, however (A) if the executive received at least three (3) but fewer than five (5) full-year bonuses, the amount will be an average of the full-year bonuses the executive received; (B) if the executive received fewer than three (3) full-year bonuses, the amount will be the average of any full-year bonuses received and 100% of the target bonus in effect for the year of termination; and (C) if any full-year bonus referred to above was determined using a formula based on a percentage of the executive’s business unit pre-tax income or other similar measure of business unit operating results, including awards made under a pool arrangement where the pool was determined based on business unit pre-tax income or other similar measure, the bonus for purpose of this calculation shall not exceed the greater of 100% of the executive’s base salary in effect immediately prior to the executive’s date of termination or 100% of the executive’s annual base salary in effect immediately prior to the change in control (such calculation, the “bonus amount”)) and (ii) the number of days the executive officer remained employed through the fiscal year in which the date of termination occurs, reduced by any amounts paid from First Horizon’s annual incentive plan for the fiscal year in which the date of termination occurs;
| • |  | a lump sum cash payment equal to three (3) times (two (2) times for one executive officer who is not a named executive officer) the sum of (i) the executive officer’s highest annual

115

|  |  | rate of base salary during the twelve (12) months prior to the date of termination plus (ii) the bonus amount;
| • |  | continued medical, dental and life insurance benefits for up to eighteen (18) months following the date of termination or until commencement of equivalent benefits from a new employer, provided that the executive officer continues to pay an amount equal to the executive officer’s contribution as in effect prior to the date of the change in control or the date of termination, as applicable;
| • |  | full vesting of any unvested equity awards upon the date of termination, with any First Horizon stock options or similar awards remaining exercisable for the greater of (i) the period remaining for exercise provided by the terms of each applicable award or its related plan or (ii) 90 days after the date of termination or, if earlier, until they would have expired but for the executive officer’s termination;
| • |  | reasonable outplacement services through the last day of the second (2 nd) calendar year following the calendar year during which the executive officer’s termination of employment occurred; and
| • |  | for Messrs. Jordan and Tuggle and one (1) additional executive officer who is not a named executive officer, each of whom is party to a CIC agreement entered into prior to 2008, a gross up payment covering any excise taxes imposed by Section 4999 of the Code. (First Horizon does not expect that the merger will constitute a change in control for purposes of Sections 280G or 4999 of the Code in relation to First Horizon.) The CIC agreements with Messrs. Losch, Kisber and Popwell and certain other executive officers who are not named executive officers contain a Section 280G “net-better” cutback provision, which provides that, if the total payments to the executive officer upon a termination would exceed the applicable threshold under the Code), then those payments will be reduced to the applicable threshold to avoid the imposition of the excise taxes under Section 4999 of the Code in the event, and only in the event, such reduction would result in a better after-tax result for the executive officer.

For an estimate of the value of the payments and benefits described above that would be payable to First Horizon’s named executive officers upon a qualifying termination in connection with the merger, see the section entitled “—Quantification of Payments and Benefits to First Horizon’s Named Executive Officers” beginning on page 117. The estimated aggregate amount that would be payable to First Horizon’s four (4) executive officers who are not named executive officers under their CIC agreements if the merger were to be completed and they were to experience a qualifying termination on June 30, 2020, based on base salary rate and target bonus as of March 2, 2020, is $13,789,746. The amounts in this paragraph with respect to the executive officers’ equity awards were determined using equity awards outstanding as of March 2, 2020 (other than the closing incentive awards, as described and quantified above) and a price per share of First Horizon common stock of $17.05 (the average closing market price of First Horizon common stock over the first five (5) business days following the public announcement of the merger on November 4, 2019) and, for purposes of unvested First Horizon performance stock units, target performance. These amounts do not attempt to forecast any additional equity or cash award grants, issuances or forfeitures that may occur prior to the closing and do not reflect the closing incentive awards or any First Horizon equity awards that are expected to vest in accordance with their terms prior to June 30, 2020. As a result of the foregoing assumptions, which may or may not actually occur or be accurate on the relevant date, the actual amounts, if any, to be received by First Horizon’s executive officers may materially differ from the amounts set forth above.

Membership on the Combined Company’s Board of Directors

The board of directors of the combined company and the combined bank after the merger will have seventeen (17) members, including Mr. Jordan and eight (8) other continuing First Horizon directors.

116

Indemnification and Insurance

First Horizon’s directors and executive officers are entitled to continued indemnification and insurance coverage.

Quantification of Payments and Benefits to First Horizon’s Named Executive Officers

This section sets forth the information required by Item 402(t) of the SEC’s Regulation S-K regarding compensation for each named executive officer of First Horizon that is based on, or otherwise relates to, the merger. This compensation is referred to as “golden parachute” compensation by the applicable SEC disclosure rules, and in this section such term is used to describe the merger-related compensation payable to First Horizon’s named executive officers. The “golden parachute” compensation payable to these individuals is subject to a non-binding advisory vote of holders of First Horizon common stock, as described in the section entitled “First Horizon Proposals—Proposal 3: First Horizon Compensation Proposal” beginning on page 56. The table below sets forth, for the purposes of this golden parachute disclosure, the amount of payments and benefits (on a pre-tax basis) that each of First Horizon’s named executive officers would receive, using the following assumptions:

| • |  | the effective time will occur on June 30, 2020 (which is the assumed date solely for purposes of this golden parachute compensation disclosure);
| • |  | each of First Horizon’s named executive officers will experience a qualifying termination under their CIC agreements at such time;
| • |  | the named executive officer’s base salary rate and annual target bonus remain unchanged from those in place as of March 2, 2020;
| • |  | equity awards that were outstanding as of March 2, 2020;
| • |  | a price per share of First Horizon common stock of $17.05 (the average closing market price of First Horizon common stock over the first five (5) business days following the public announcement of the merger on November 4, 2019);
| • |  | for purposes of the unvested First Horizon performance stock units (“First Horizon PSUs”) set forth in the table, target performance; and
| • |  | for the unvested First Horizon restricted stock units (“First Horizon RSUs”) and First Horizon PSUs set forth in the table, includes associated dividend equivalent rights accrued thereon.

The calculations in the table do not include amounts that First Horizon’s named executive officers were already entitled to receive, or were vested in, as of the date of this joint proxy statement/prospectus. The calculations in this table also do not include the closing incentive awards discussed in the section entitled “—Letter Agreements between First Horizon and Certain of its Executive Officers” beginning on page 114, as those awards are contingent upon and will vest based on services provided to First Horizon following the closing, including upon a termination other than for “cause.” In addition, these amounts do not attempt to forecast any additional equity award grants, issuances or forfeitures that may occur, or future dividends or dividend equivalents that may be accrued, prior to the completion of the merger and do not reflect any First Horizon equity or other incentive awards that are expected to vest in accordance with their terms prior to June 30, 2020. As a result of the foregoing assumptions, which may or may not actually occur or be accurate on the relevant date, including the assumptions described in the footnotes to the table, the actual amounts, if any, to be received by a named executive officer may materially differ from the amounts set forth below.

Treatment of all such equity awards is “double trigger,” and such awards are payable only upon the named executive officer’s qualifying termination within thirty-six (36) months following the closing.

Does not take into account any illiquidity discounts.

Interests of Certain IBKC Directors and Executive Officers in the Merger

In considering the recommendation of the IBKC board of directors to vote to approve the IBKC merger proposal, holders of IBKC common stock should be aware that the directors and executive officers of IBKC may have interests in the merger that are different from, or in addition to, the interests of holders of IBKC common stock generally and that may create potential conflicts of interest. The IBKC board of directors was aware of these interests and considered them, among other matters, in evaluating and negotiating the merger agreement and approving the merger agreement and in recommending to holders of IBKC common stock that they vote to approve the IBKC merger proposal. For more information, see the sections entitled “The Merger—Background of the Merger” beginning on page 66 and “The Merger—IBKC’s Reasons for the Merger; Recommendation of IBKC’s Board of Directors” beginning on page 76. Any such interests are described in more detail below.

Treatment of IBKC Equity Awards

The IBKC stock options, IBKC phantom stock awards, IBKC restricted stock awards and IBKC PSUs (collectively, the “IBKC equity awards”) held by IBKC’s directors and executive officers immediately prior to the effective time will be generally treated in the same manner as those IBKC equity awards held by other employees of IBKC and in each case, except as described below, will be treated in accordance with the terms and conditions that were applicable to such awards before the effective time, unless otherwise mutually agreed by the parties and a holder of any IBKC equity award.

| • |  | IBKC Stock Options. At the effective time, each outstanding option to purchase shares of IBKC common stock under IBKC’s equity incentive plans (each, an “IBKC stock option”) that was granted prior to November 3, 2019 shall vest and accelerate in full and shall, automatically and without any required action on the part of the holder thereof, be converted

119

|  |  | into an option (a “First Horizon stock option”) to purchase (i) a number of shares of First Horizon common stock (rounded down to the nearest whole share) equal to the product of (A) the total number of shares of IBKC common stock subject to such IBKC stock option immediately prior to the effective time multiplied by (B) the exchange ratio, (ii) at an exercise price per share of First Horizon common stock (rounded up to the nearest whole cent) equal to the quotient of (A) the exercise price per share of IBKC common stock of such IBKC stock option immediately prior to the effective time divided by (B) the exchange ratio (as it may be adjusted as set forth in the merger agreement), with each such First Horizon stock option subject to the same terms and conditions, including exercisability and forfeiture terms, as applied to the corresponding IBKC stock option immediately prior to the effective time, except as expressly set forth in the merger agreement.
| • |  | IBKC Restricted Stock Awards. At the effective time, each outstanding IBKC restricted stock award that was granted prior to November 3, 2019 shall vest and accelerate in full and shall, automatically and without any required action on the part of the holder thereof, be cancelled and shall only entitle the holder to receive immediately following the effective time, the merger consideration, less applicable taxes required to be withheld with respect to such vesting.
| • |  | IBKC PSU Awards. At the effective time, each outstanding IBKC PSU award that was granted prior to November 3, 2019 shall vest and accelerate in full and shall, automatically and without any required action on the part of the holder thereof, be cancelled and shall only entitle the holder to receive (without interest), immediately following the effective time, the merger consideration (less applicable taxes required to be withheld with respect to such vesting) with the number of IBKC PSUs (including any applicable dividend equivalents) entitled to receive the merger consideration determined based on the greater of (A) the target performance level or (B) the actual performance level through September 30, 2019 as reasonably determined by the compensation committee of the board of directors of IBKC, multiplied by (ii) the exchange ratio; provided that, with respect to any IBKC PSU award that constitutes nonqualified deferred compensation subject to Section 409A of the Internal Revenue Code and that is not permitted to be paid at the effective time without triggering a tax or penalty under Section 409A of the Code, such payment will be made at the earliest time permitted under the applicable IBKC equity incentive plan and award agreement that will not trigger a tax or penalty under Section 409A of the Code.
| • |  | IBKC Phantom Stock Awards. At the effective time, each outstanding IBKC phantom stock award that was granted prior to November 3, 2019 shall vest and be cancelled and automatically and without any required action on the part of the holder thereof entitle the holder of such IBKC phantom stock award to receive (without interest), on the first regularly scheduled payroll date of First Horizon following the closing date, an amount in cash (rounded to the nearest cent and less applicable taxes required to be withheld with respect to such vesting) determined by multiplying (i) the closing price of one share of First Horizon common stock on the closing date by (ii) the number of shares of First Horizon common stock underlying such IBKC phantom stock award (as determined by multiplying (A) the number of shares of IBKC common stock (including any applicable dividend equivalents) underlying such IBKC phantom stock award by (B) the exchange ratio (the “phantom stock consideration”); provided that, to the extent a holder of IBKC phantom stock awards has made a deferral election in respect of payments pursuant to such IBKC phantom stock awards, the applicable portion of the phantom stock consideration will be credited to such holder’s deferred compensation account under IBKC’s Executive Nonqualified Excess Plan.
| • |  | Future Grants of Equity Awards. At the effective time, each IBKC equity award granted on or after the date of the merger agreement and not in violation of the merger agreement that expressly provides for treatment in connection with the occurrence of the effective time that is different from the treatment prescribed in the merger agreement as set forth above, or as mutually agreed by the parties and a holder of any IBKC equity award, will be converted into an equity award denominated in shares of First Horizon common stock (rounded down to the

120

|  |  | nearest whole number) (a “converted equity award”) equal to the product of (i) the number of shares of IBKC common stock subject to such IBKC equity award immediately prior to the effective time multiplied by (ii) the exchange ratio; provided, that to the extent any such converted equity award is a IBKC stock option (a “converted stock option”), the exercise price per share of such converted stock option will be equal to the quotient (rounded up to the nearest whole cent) of (A) the exercise price per share of IBKC common stock of such IBKC stock option immediately prior to the effective time divided by (B) the exchange ratio. Notwithstanding the above, any IBKC equity awards granted on or after November 3, 2019 and prior to the closing date will not provide for automatic “single-trigger” acceleration of vesting or payment at the effective time of the merger, but may instead provide for “double-trigger” vesting upon a termination without “cause” or for “good reason” following the effective time of the merger.

For an estimate of the amounts that would be realized by each of IBKC’s named executive officers upon the effective time and upon a termination without “cause” or for “good reason” (each as defined in the applicable award agreement and each a “qualifying termination”) immediately following the effective time in respect of their unvested IBKC equity awards that are outstanding on March 2, 2020 (excluding the closing incentive awards, as described below and any associated dividends and dividend equivalent rights accrued thereon), see the section entitled “—Quantification of Payments and Benefits to IBKC’s Named Executive Officers” beginning on page 126.

The estimated aggregate amount that would be realized by the nine (9) IBKC executive officers who are not named executive officers (each, referred to as a “non-NEO”) upon the effective time and upon a termination without “cause” or for “good reason” (each as defined in the applicable award agreement and each a “qualifying termination”) immediately following the effective time in respect of their unvested IBKC equity awards that are outstanding on March 2, 2020 (excluding the closing incentive awards, as described and quantified below, and any associated dividends and dividend equivalent rights accrued thereon) if the merger were to be completed and they experienced a qualifying termination on June 30, 2020 is $8,075,542, and for purposes of IBKC PSUs, based on the greater of performance as of September 30, 2019 or target performance, as applicable. The estimated aggregate amount that would be realized by the nine (9) non-employee directors of IBKC in connection with the vesting of their unvested IBKC equity awards that are outstanding on March 2, 2020 (including associated dividends accrued thereon) if the merger were to be completed is $951,876. The amounts in this paragraph were determined using a price per share of IBKC common stock of $77.20 (the average closing market price of IBKC common stock over the first five (5) business days following the public announcement of the merger on November 4, 2019). These amounts do not attempt to forecast any additional equity award grants, issuances or forfeitures that may occur prior to the closing and, with respect to IBKC’s executive officers, do not reflect any IBKC equity awards that are expected to vest in accordance with their terms prior to June 30, 2019. As a result of the foregoing assumptions, which may or may not actually occur or be accurate on the relevant date, the actual amounts, if any, to be received by IBKC’s non-NEOs and IBKC’s non-employee directors may materially differ from the amounts set forth above.

Chairman Letter Agreement of Mr. Byrd

On November 3, 2019, First Horizon and Mr. Byrd entered into a letter agreement (the “Byrd letter agreement”) with respect to the terms of Mr. Byrd’s employment with and service to the combined company and combined bank following the closing. The Byrd letter agreement provides for the following:

| • |  | Mr. Byrd will serve as the Executive Chairman of the combined company and combined bank through the second (2 nd) anniversary of the closing or such earlier time that Mr. Byrd and the Chief Executive Officer of the combined company jointly determine (or 75% of the combined company’s board of directors should resolve) that an Executive Chairman is no longer required for the successful integration of First Horizon and IBKC (the “chairman succession date”). For the period commencing upon the chairman succession date and ending on the fifth

121

|  |  | (5 th) anniversary of the closing date, Mr. Byrd will serve as Special Advisor to the Chief Executive Officer of the combined company and combined bank.
| • |  | Mr. Byrd will be employed by the combined company and combined bank through the second (2 nd) anniversary of the closing date (the “employment period”) and Mr. Byrd’s annual target direct compensation and form of long-term incentive awards will be in the same amounts and on the same terms, and with the same payout determinations and amounts, as those that apply to the Chief Executive Officer of First Horizon (subject to certain exceptions, including that Mr. Byrd’s base salary and target annual incentive will not be less than each as provided immediately before the closing date). During the employment period, Mr. Byrd will be eligible to participate in the same employee benefit plans as are made available to similarly situated executives of the combined company and combined bank and he will continue to receive the same perquisites as were made available to him as of immediately prior to the closing.
| • |  | For the thirty-six (36)-month period immediately following the employment period (the “consulting period”), Mr. Byrd will serve as a consultant to the combined company and combined bank and will receive an annual consulting fee equal to (i) $3,750,000 for the first two (2) years and (ii) $3,500,000 for the third (3 rd) year. Through the end of the consulting period, Mr. Byrd will continue to have access to administrative support, office space and security arrangements provided by the combined company.
| • |  | As of the closing date, the combined company will grant Mr. Byrd a one-time cash integration and continuity award in the amount of $5,000,000, payable in quarterly installments over five (5) years; provided that any unpaid portion of the award will be paid to him in a lump sum at the time that Mr. Byrd transitions from Executive Chairman to Special Advisor or upon Mr. Byrd’s earlier termination other than by First Horizon for “cause” or by Mr. Byrd without “good reason” (each as defined in the Byrd letter agreement). Any paid portion of the integration and continuity award will be subject to repayment and recovery in full by First Horizon and any unpaid portion will be forfeited upon a (i) termination for “cause,” (ii) resignation other than for “good reason” or (iii) material violation of the restrictive covenants in the Byrd letter agreement (as described below).
| • |  | If Mr. Byrd’s employment or consulting service, as applicable, is terminated by First Horizon other than for “cause” or by him for “good reason,” such termination will not affect the compensation to be provided to him under the Byrd letter agreement, subject to his continued compliance with restrictive covenants. If Mr. Byrd dies during the employment period or the consulting period, any remaining unpaid amounts due to him under the Byrd letter agreement (determined assuming target performance) will be paid to his estate, to the extent such unpaid amounts exceed the value of incremental life insurance benefits.
| • |  | Mr. Byrd has agreed to be bound by certain restrictive covenants, including non-competition and non-solicitation covenants, for the five (5)-year period following the closing date. He will also be subject to indefinite non-disparagement and confidentiality covenants.
| • |  | Under the Byrd letter agreement, “good reason” means a material violation by First Horizon of the terms of the Byrd letter agreement that has not been cured within 30 days after written notice has been given by Mr. Byrd to the Chief Executive Officer of First Horizon (provided that such notice must be given within 30 days of Mr. Byrd becoming aware of such event). Mr. Byrd will also not be found to have engaged in “cause” or to have materially violated any of the restrictive covenants in the Byrd letter agreement until he has had delivered to him resolution duly adopted by the vote of not less than three-quarters (75%) of the entire membership of the Board that he was guilty of such conduct constituting cause or the material violation and specifying the particulars thereof in detail.

The Byrd letter agreement does not affect the severance and other benefits under the terms of Mr. Byrd’s existing employment agreement (the “Byrd employment agreement”), dated December 31, 2008, by and among IBKC, IBERIABANK and Mr. Byrd. Any amounts due to him under the Byrd

122

employment agreement will be funded and maintained in a rabbi trust along with the integration and continuity award described above. The severance and other benefits due to Mr. Byrd upon a termination without “cause” or for “good reason” under the Byrd employment agreement will be paid to Mr. Byrd in connection with his future “separation from service” with the combined company and combined bank, which would occur upon the commencement of his service as Special Advisor. Mr. Byrd’s cash severance is equal to 100% of his 280G Maximum (generally defined as 2.99 times the applicable executive’s average compensation over the previous five (5) years). Under the Byrd employment agreement, Mr. Byrd is also entitled to the continuation of the group insurance, life insurance, health and accident, disability and other employee benefits provided to Mr. Byrd prior to his termination for thirty-nine (39) months following termination at no cost to Mr. Byrd. Mr. Byrd is also entitled to the reimbursement of excise taxes incurred under Section 4999 of the Code, including with respect to amounts and benefits paid to him in connection with the Byrd letter agreement and the Byrd closing incentive award (as described below).

IBKC Closing Incentive Award Letter with Daryl G. Byrd

On November 3, 2019, IBKC and IBERIABANK entered into a letter agreement (the “closing incentive award letter”) with Mr. Byrd, providing for a closing incentive award in the form of a restricted stock award (the “Byrd closing incentive award”). The award was granted effective November 18, 2019 and had a grant-date value of $5,000,000, with the number of shares determined using the volume average weighted price of a share of IBKC common stock over the ten (10) trading days immediately prior to November 18, 2019.

The Byrd closing incentive award will vest in full on the six (6)-month anniversary of the closing date unless prior to such date Mr. Byrd voluntarily resigns without “good reason” or Mr. Byrd’s employment is terminated for “cause” (each as defined in the Byrd letter agreement, described above). The Byrd closing incentive award will be forfeited if the merger does not close, and it is not transferable during Mr. Byrd’s service as Executive Chairman of the combined company. The Byrd closing incentive award will be subject to repayment and recovery in full upon a (i) termination for “cause,” (ii) resignation other than for “good reason” (each as defined in the Byrd letter agreement) or (iii) material violation of the restrictive covenants contained in the Byrd letter agreement, in each case, prior to the second (2 nd) anniversary of the closing date.

In connection with the closing, the Byrd closing incentive award will automatically be converted into an equity award denominated in shares of First Horizon common stock based on the exchange ratio and will remain outstanding and eligible to vest in accordance with its terms.

IBKC Letter Agreements

Anthony J. Restel and Michael J. Brown and two (2) IBKC non-NEOs, have entered into letter agreements (the “letter agreements”) in recognition of their new roles at the combined company and any corresponding change in duties and responsibilities. The awards were granted in the form of restricted stock awards (each, an “executive closing incentive award” and, together with the Byrd closing incentive award, the “closing incentive awards”) effective November 18, 2019 with the following grant date values: Mr. Restel, $1,350,000; Mr. Brown, $1,400,000; and for two (2) other IBKC non-NEOs, $1,688,000 (in the aggregate), with the number of shares determined using the volume average weighted price of a share of IBKC common stock over the ten (10) trading days immediately prior to November 18, 2019.

Each executive closing incentive award will vest in full on the first anniversary of the closing date or, if earlier, upon any termination of employment other than a termination for “just cause” or resignation without “good reason” (each as defined in the letter agreements). All executive closing incentive awards will be forfeited if the merger does not close and will be subject to repayment and recovery in full if the executive materially violates any of the restrictive covenants outlined in the letter agreements. In connection with the closing, each executive closing incentive award will automatically be converted into an equity award denominated in shares of First Horizon common

123

stock based on the exchange ratio and will remain outstanding and eligible to vest in accordance with its terms.

To incentivize the executive officers to remain employed with the combined company and combined bank following the closing, the letter agreements (with the exception of one (1) agreement for a non-NEO) also provide that Messrs. Restel and Brown and one (1) non-NEO, will receive a future payment equal to the amount of potential severance payments outlined in each executive officer’s preexisting change in control severance agreement with IBKC and IBERIABANK (each, a “CIC severance agreement”) that the executive officer would otherwise have become entitled to in connection with the closing (which amount would be equal to 100% of each executive officer’s 280G Maximum (generally defined as 2.99 times the applicable executive’s average compensation over the previous five (5) years)). These severance payments will be made upon the occurrence of any future “separation from service” (as contemplated by Section 409A of the Code). Prior to the closing, the compensation committee of the board of directors of IBKC will calculate the amount of severance to be paid as if the executive officer had resigned immediately following the closing and credit such amount, within ten (10) business days following the closing, as a deferred compensation balance under IBKC’s Executive Nonqualified Excess Plan and such amount will be funded and maintained in a rabbi trust. The letter agreements also affirm that such executive officers will remain entitled to up to thirty-nine (39) months’ continued coverage under the executive officer’s medical and life benefit plans upon a termination other than for “just cause” during the thirty-six (36)-month period following the closing and the reimbursement of excise taxes incurred under Section 4999 of the Code and that each will be entitled to. The other non-NEO will remain entitled to severance benefits under her CIC severance agreement without modification, as described below.

Under the letter agreements, Messrs. Restel and Brown and the two (2) other IBKC executive officers have agreed to be bound by certain restrictive covenants, including non-competition and non-solicitation covenants, for the twelve (12)-month period following the effective time. They will also be subject to indefinite non-disparagement and confidentiality covenants.

For an estimate of the value of the payments and benefits described above that would be payable to Messrs. Restel and Brown under their letter agreements with respect to their CIC severance agreements in connection with the merger, see the section entitled “—Quantification of Payments and Benefits to IBKC’s Named Executive Officers” beginning on page 126. The estimated aggregate amount that would be payable to the IBKC non-NEO who is party to a letter agreement with respect to her CIC severance agreement if the merger were to be completed is $6,628,932, based on base salary rate and annual target bonus as of March 2, 2020.

Acceleration of IBKC Restricted Stock Awards

In connection with the merger agreement, the compensation committee of the board of directors of IBKC accelerated the vesting of the performance-based restricted stock awards previously awarded as a special Acquisition Incentive, dated as of August 1, 2017, and as amended as of April 30, 2018), held by Mr. Byrd (35,000 shares), Mr. Restel (20,000 shares) Mr. Brown (20,000 shares) and one non-NEO (15,000 shares), such that such restricted stock awards became fully vested upon the execution of the merger agreement.

IBKC Executive Nonqualified Excess Plan

Certain of IBKC’s executive officers and non-employee directors have balances under the IBKC Executive Nonqualified Excess Plan. During the thirty (30) days preceding or the twelve (12) months following the effective time, the compensation committee of the IBKC board may exercise its discretion to terminate such plan and distribute the account balance of each participant in full within twelve (12) months after such termination. To the extent that an IBKC executive officer has made an election to receive a distribution upon a change in control under such plan or undergoes a separation from service within the first thirty (30) days following the effective time, payment in respect of such distributions shall be made no later than sixty (60) days following such termination

124

or the effective time, as applicable. The aggregate account balances in such plan held by IBKC executive officers and non-employee directors as of March 2, 2020 were $14,229,253 and $757,941, respectively.

IBKC Change in Control Severance Agreements

Each of Messrs. Restel and Brown, and Fernando Perez-Hickman and Jefferson G. Parker, and nine (9) IBKC non-NEOs, is party to a CIC severance agreement. For a description of certain amendments to the CIC severance agreements with Messrs. Restel and Brown and one (1) non-NEO pursuant to letter agreements that will be assumed by the combined company and the combined bank at the closing, see the section entitled “—IBKC Letter Agreements” beginning on page 123. At the closing, the CIC severance agreements with Messrs. Perez-Hickman and Parker, and the remaining eight (8) non-NEOs will be assumed by the combined company and the combined bank.

Mr. Parker and two (2) non-NEOs would become entitled to receive a cash severance payment under their CIC severance agreements equal to a specified percentage of the executive officer’s 280G Maximum (100% for Mr. Parker and 70% for the other two (2) non-NEOs) in the event Mr. Parker or such executive officers resign for “good reason” or are terminated without “just cause” (each as defined in the applicable CIC severance agreement) during the thirty-six (36)-month period following the closing or resign for any reason other than “just cause” in the thirty (30)-day period following the closing. Each such executive officer would also be entitled to up to thirty-nine (39) months of continued coverage under the executive officer’s medical and life benefit plans and the reimbursement of excise taxes incurred under Section 4999 of the Code. IBKC and IBERIABANK may enter into amendment agreements with Mr. Parker and such non-NEOs with respect to their CIC severance agreements to provide that each will receive a future payment upon any “separation from service” (as contemplated by Section 409A of the Code) equal to the amount of potential severance payments outlined in the applicable CIC severance agreement that Mr. Parker and such executive officers would otherwise have become entitled to in connection with the closing. For an estimate of the value of the payments and benefits described above that would be payable to Mr. Parker under his CIC severance agreement in connection with the merger, see the section entitled “—Quantification of Payments and Benefits to IBKC’s Named Executive Officers” beginning on page 126. The estimated aggregate amount that would be payable to the other two (2) non-NEOs with such CIC severance agreements if the merger were to be completed is $4,328,775, based on base salary rate and annual target bonus as of March 2, 2020.

With respect to Mr. Perez Hickman and three (3) non-NEOs, in the event Mr. Perez Hickman or such executive officers resign for “good reason” or are terminated without “just cause” (each as defined in the applicable CIC severance agreement) during the twenty-four (24)-month period following the closing, Mr. Perez Hickman and such executive officers would be entitled to a lump sum cash severance payment equal to the sum of (i) a pro rata bonus for the year of termination and (ii) two and one-half (2.5) times the sum of the applicable executive officer’s (A) then-current base salary and (B) bonus, determined as follows in the stated order of priority: (I) if applicable, the executive officer’s guaranteed bonus, (II) if the executive officer is not entitled to a guaranteed bonus, the target bonus for the year, (III) if the executive officer does not have a target bonus, the average of the annual bonuses awarded to such executive officer for the three most recently completed fiscal years, or (IV) if the executive officer was not employed during each of the three most recently completed fiscal years, then the average of the annual bonuses awarded to such executive officer for each fiscal year such executive officer was eligible to receive a bonus. Additionally, each such executive officer would be entitled to a lump sum cash payment in an amount equal to the sum of the aggregate monthly premium that would be paid by such executive officer and the IBKC to obtain group health coverage and group term life insurance, multiplied by thirty-six (36), less applicable withholding taxes. For an estimate of the value of the payments and benefits described above that would be payable to Mr. Perez Hickman under his CIC severance agreement in connection with the merger, see the section entitled “—Quantification of Payments and Benefits to IBKC’s Named Executive Officers” beginning on page 126. The estimated aggregate amount that would be payable to the other three (3) non-NEOs with such CIC severance

125

agreements if the merger were to be completed is $5,129,581, based on base salary rate and annual target bonus as of March 2, 2020.

With respect to the remaining three (3) IBKC non-NEOs, upon a resignation for “good reason” or a termination without “just cause” (each as defined in the applicable CIC severance agreement) during the thirty-six (36)-month period following the closing, such executive officer would be entitled to a lump-sum payment equal to a specified percentage (ranging from 35% to 70%) of the executive officer’s 280G Maximum. Such executive officers would also be entitled to up to thirty-nine (39) months of continued coverage under the executive officer’s medical and life benefit plans and the reimbursement of excise taxes incurred under Section 4999 of the Code. The estimated aggregate amount that would be payable to the three (3) non-NEOs with such CIC severance agreements if the merger were to be completed is $4,561,977, based on base salary rate and annual target bonus as of March 2, 2020.

Indemnification and Insurance

Pursuant to the terms of the merger agreement, from and after the effective time, the combined company would indemnify certain persons, including IBKC’s directors and executive officers. In addition, for a period of six (6) years from the effective time, the combined company would maintain an insurance policy for the benefit of certain persons, including IBKC’s directors and executive officers. For additional information, see “The Merger Agreement—Covenants and Agreements—Director and Officer Indemnification and Insurance” beginning on page 151.

Membership of the Board of Directors of the Combined Company and Bank

The board of directors of the combined company and combined bank following the merger will consist of seventeen (17) directors, including Mr. Byrd and seven (7) other members of the IBKC board of directors, designated by IBKC. Other than Mr. Byrd, as of the date of this joint proxy statement/prospectus, no decisions have been made with respect to which current IBKC directors will be appointed to the board of directors of the combined company and combined bank in the merger.

Quantification of Payments and Benefits to IBKC’s Named Executive Officers

This section sets forth the information required by Item 402(t) of the SEC’s Regulation S-K regarding compensation for each named executive officer of IBKC that is based on, or otherwise relates to, the merger. This compensation is referred to as “golden parachute” compensation by the applicable SEC disclosure rules and in this section such term is used to describe the merger-related compensation payable to IBKC’s named executive officers. The “golden parachute” compensation payable to these individuals is subject to a non-binding advisory vote of holders of IBKC common stock, as described in the section entitled “IBKC Proposals—Proposal 2: IBKC Compensation Proposal” beginning on page 62. The table below sets forth, for the purposes of this golden parachute disclosure, the amount of payments and benefits (on a pre-tax basis) that each of IBKC’s named executive officers would receive, using the following assumptions:

| • |  | the effective time will occur on June 30, 2020 (which is the assumed date solely for purposes of this golden parachute compensation disclosure);
| • |  | Mr. Byrd will experience a termination without “cause” under the Byrd employment agreement and Messrs. Restel, Brown, Perez-Hickman and Parker will each experience a termination without “just cause” under their CIC severance agreements at such time;
| • |  | the named executive officers’ base salary rate and annual target bonus remain unchanged from those in place as of March 2, 2020;
| • |  | equity awards that are outstanding as of March 2, 2020;

126

| • |  | a price per share of IBKC common stock of $77.20 (the average closing market price of IBKC common stock over the first five (5) business days following the public announcement of the merger on November 4, 2019);
| • |  | for purposes of the unvested IBKC PSUs set forth in the table, the greater of performance as of September 30, 2019 or target performance, as applicable; and
| • |  | for the unvested IBKC PSUs set forth in the table, includes associated dividend equivalent rights accrued thereon.

The calculations in the table do not include amounts that IBKC’s named executive officers were already entitled to receive or vested in as of the date of this joint proxy statement/prospectus. The calculations in this table also do not include the Byrd closing incentive award discussed in the section entitled “—IBKC Closing Incentive Award Letter with Daryl G. Byrd” or the executive closing incentive awards discussed in the section entitled “—IBKC Letter Agreements” beginning on page 123, as those awards are contingent upon and will vest based on services provided to First Horizon following the closing, including upon a termination other than for “just cause” (or “cause” in the case of Mr. Byrd). In addition, the calculations in the table do not include any payments or other post-closing compensation entitlements pursuant to the Byrd letter agreement (including the integration and continuity award), which are compensation for Mr. Byrd’s post-closing employment and service and based on his post-closing service to the combined company and the combined bank under a bona fide employment agreement (see the section entitled “—Chairman Letter Agreement of Mr. Byrd” beginning on page 121 for a description of the Byrd letter agreement). In addition, these amounts do not attempt to forecast any additional equity award grants, issuances or forfeitures that may occur, or future dividends or dividend equivalents that may be accrued, prior to the completion of the merger and do not reflect any IBKC equity or other incentive awards that are expected to vest in accordance with their terms prior to June 30, 2020. As a result of the foregoing assumptions, which may or may not actually occur or be accurate on the relevant date, including the assumptions described in the footnotes to the table, the actual amounts, if any, to be received by a named executive officer may materially differ from the amounts set forth below.

| (1) |  | Represents cash amounts payable to each of the named executive officers, except for Mr. Byrd, pursuant to the applicable CIC severance agreement (as modified by the applicable letter agreement, in the case of Messrs. Restel and Brown). Mr. Byrd is entitled to cash amounts payable pursuant to the Byrd employment agreement. Each of Messrs. Byrd, Restel and Brown is entitled to receive cash severance equal to 100% of his 280G Maximum following his “separation from service” following the effective time, regardless of the reason for such separation. Upon a termination without “just cause” or resignation for “good reason” during the thirty-six (36)-month period following the effective time, or resignation for any reason in the thirty (30) days following the effective time, Mr. Parker would be entitled to 100% of his 280G Maximum. The foregoing cash amounts due to each of Messrs. Byrd, Restel, Brown and Parker are “single-trigger” and not conditioned upon a termination for “cause” or “just cause” or resignation for “good reason.” Pursuant to his CIC severance agreement, which is “double-trigger,” upon a termination without “just cause” or resignation for “good reason” during the twenty-four (24)-month period following the effective time, Mr. Perez-Hickman would be

127

|  |  | entitled to (i) a lump sum cash severance payment equal to the sum of (A) a pro-rata bonus for the year of termination and (B) two and one-half (2.5) times the sum of (I) his then-current base salary and (II) bonus and (ii) a lump sum cash payment in an amount equal to the sum of the aggregate monthly premium that would be paid by him and IBKC to obtain group health coverage and group term life insurance, multiplied by thirty-six (36), less applicable withholding taxes. Mr. Perez-Hickman’s bonus for the purpose of the foregoing clause (II) is determined as follows in the stated order of priority: (i) if applicable, his guaranteed bonus, (ii) if he is not entitled to a guaranteed bonus, the target bonus for the year, (iii) if he does not have a target bonus, the average of the annual bonuses awarded to him for the three most recently completed fiscal years, or (iv) that if he has not been employed during each of the three most recently completed fiscal years, then the amount shall be the average of the annual bonuses awarded to him for each fiscal year he was eligible to receive a bonus. The confidential disclosure schedules to the merger agreement permit, but do not require, the payment of a pro rata annual bonus to an employee who experiences a qualifying termination prior to or at the closing, based on actual performance, pro-rated for the period of employment during the year and payable at the same time that bonuses are otherwise payable. The payment of such “double-trigger” pro rata bonuses has not yet been approved by the compensation committee of the board of directors of IBKC, however a pro-rata bonus based on each named executive officer’s 2019 target bonus has been included in the below column “Pro-Rata Bonus,” other than Mr. Perez-Hickman, who is entitled to a pro-rata bonus amount pursuant to his CIC agreement (which amount is included in the below column “IBKC Cash Severance”).

Name |  | IBKC Cash Severance ($) |  | Pro Rata Bonus ($) |  | Total ($)
Daryl G. Byrd |  |  | $ |  | 14,979,262 |  |  |  | $ |  | 657,637 |  |  |  | $ |  | 15,636,898 |

| (2) |  | All IBKC equity awards granted prior to November 3, 2019 are “single-trigger” and will accelerate and vest at the effective time in accordance with the terms and conditions applicable to such awards prior to the effective time. IBKC equity awards granted on or following November 3, 2019 to the named executive officers will not vest upon the closing, but may contain “double trigger” vesting provisions upon a termination without “cause” or resignation for “good reason” following the effective time. The below column “Unvested PSUs” is inclusive of the value of re-invested dividend equivalents underlying such IBKC PSUs in accordance with the terms and conditions of the PSU award agreements. The below column “Restricted Stock Accelerated Effective November 3, 2019” describes the value of the restricted stock awards held by each of Messrs. Byrd, Restel and Brown that accelerated and vested upon the execution of the merger agreement based on the per share price of IBKC common stock described above. The below column “Unvested Restricted Stock” does not include the value of restricted stock issued pursuant to the closing incentive awards held by Messrs. Byrd, Restel and Brown. For a description of the closing incentive awards, which are “double-trigger” and would accelerate and vest upon a termination of employment of employment other than for “cause” or a voluntary resignation without “good reason,” see “Interests of Certain IBKC Directors and Executive Officers in the Merger—IBKC Closing Incentive Award Letter with Daryl G. Byrd” beginning on page 123 and “Interests of Certain IBKC Directors and Executive Officers in the Merger—IBKC Letter Agreements” beginning on page 123.

Byrd, Restel, Brown and Parker, pursuant to the Byrd employment agreement or applicable CIC severance agreement for each of Messrs. Restel, Brown and Parker (as modified by the applicable letter agreement, in the case of Messrs. Restel and Brown), each of which is a “single-trigger” arrangement.
| (4) |  | Represents taxes associated with “excess parachute payments” pursuant to the Byrd employment agreement or applicable CIC severance agreement for each of Messrs. Restel, Brown and Parker (as modified by the applicable letter agreement, in the case of Messrs. Restel and Brown), each of which is a “single-trigger” arrangement. These taxes include any excise tax imposed under Section 4999 of the Code as well as any federal, state or local tax resulting from the excise tax payment.

Governance of the Combined Company After the Merger

Bylaws

Prior to the effective time, the First Horizon board of directors will take all actions necessary to cause the bylaws of First Horizon to be amended as set forth in the merger agreement, and as so amended the bylaws of First Horizon will be the bylaws of the combined company, until thereafter amended as provided therein or in accordance with applicable law. The bylaws of First Horizon as amended pursuant to the merger agreement will implement certain governance and related matters for the combined company following completion of the merger, including: the composition of the combined company’s board of directors, the roles of the Chairman of the Board and the Chief Executive Officer and related succession matters, the role of the lead director, the composition of the committees of the board of directors and the location of the headquarters of the combined company’s regional banking business. Each of the foregoing governance matters is discussed further below.

Board of Directors

Immediately after the effective time and until the expiration date, the board of directors of the combined company and the combined bank will have seventeen (17) members, consisting of:

| • |  | the continuing First Horizon directors—the Chief Executive Officer of First Horizon as of immediately prior to the effective time and eight (8) additional members of the First Horizon board of directors as of immediately prior to the effective time, designated by First Horizon; and
| • |  | the continuing IBKC directors—the Chief Executive Officer of IBKC as of immediately prior to the effective time and seven (7) additional members of the IBKC board of directors as of immediately prior to the effective time, designated by IBKC.

As a result, immediately following the effective time, the board of directors of the combined company and the combined bank is expected to consist of D. Bryan Jordan, the current Chairman of the Board, President and Chief Executive Officer of First Horizon; Daryl G. Byrd, the current

129

President and Chief Executive Officer of IBKC; and those other directors designated by First Horizon and IBKC, as applicable.

Until the expiration date, any vacancy on the board of directors of the combined company or of the combined bank resulting from the cessation of service by any continuing IBKC director will be filled by the board of directors with a nominee selected by majority vote of the continuing IBKC directors then in office, in which case the continuing First Horizon directors will vote to approve the appointment or nomination, as applicable, of such individual, provided that any such appointment or nomination (as applicable) will be made in accordance with applicable law and the rules of the NYSE or other national securities exchange on which the combined company’s securities are listed. During this period, the continuing IBKC directors shall have the exclusive authority to nominate, by majority vote, on behalf of the board of directors, directors for election at each annual meeting, or at any special meeting at which directors are to be elected, to fill each seat previously held by a continuing IBKC director. Any additional directors who were nominated and subsequently appointed or elected to fill a vacancy created by the cessation of a continuing IBKC director shall also be considered to be a continuing IBKC director thereafter.

Until the expiration date, any vacancy on the board of directors of the combined company or of the combined bank resulting from the cessation of service by any continuing First Horizon director will be filled by the board of directors with a nominee selected by majority vote of the continuing First Horizon directors then in office, in which case the continuing IBKC directors shall vote to approve the appointment or nomination, as applicable, of such individual, provided that any such appointment or nomination (as applicable) will be made in accordance with applicable law and the rules of the NYSE or other national securities exchange on which the combined company’s securities are listed. During this period, the continuing First Horizon directors will have the exclusive authority to nominate, by majority vote, on behalf of the board of directors, directors for election at each annual meeting, or at any special meeting at which directors are to be elected, to fill each seat previously held by a continuing First Horizon director. Any additional directors who were nominated and subsequently appointed or elected to fill a vacancy by the cessation of service of a continuing First Horizon director shall also be considered to be a continuing First Horizon director thereafter.

Until the expiration date, any modification or amendment to, or repeal of, the bylaw provisions implementing the above arrangements will require the affirmative vote of at least seventy-five percent (75%) of the entire board of directors of the combined company.

Until the expiration date, First Horizon’s existing bylaw provision prohibiting the nomination of any director will attain the age of seventy-two (72) on or before the last day of his or her applicable term will not apply to any director who is already a member of, or who joins the combined company’s board of directors on, the closing date.

Chairman of the Board and Chief Executive Officer

Immediately following the effective time, D. Bryan Jordan, the current Chairman of the Board, President and Chief Executive Officer of First Horizon and First Horizon Bank, will continue to serve as President and Chief Executive Officer of the combined company and the combined bank. Immediately following the effective time, Daryl G. Byrd, current President and Chief Executive Officer of IBKC, will become the Executive Chairman of the boards of directors of the combined company and the combined bank until the chairman succession date, at which time Mr. Jordan will succeed Mr. Byrd as the Chairman of the boards of directors of the combined company and the combined bank. Thereafter, Mr. Byrd will serve as a special advisor to the Chief Executive Officer until the fifth (5 th) anniversary of the closing date.

Until the expiration date, any removal of (or failure to re-elect or nominate) Mr. Jordan or Mr. Byrd from (or to) the positions described above and in any employment agreement with Mr. Jordan or Mr. Byrd, as applicable, at the times specifically provided for above, will require the affirmative vote of at least seventy-five percent (75%) of the entire board of directors of the combined company. For a period of two (2) years following completion of the merger, any determination not

130

to nominate Mr. Jordan or Mr. Byrd as a director of the combined company or the combined bank, in each case as contemplated by their respective employment agreements, will require the affirmative vote of at least seventy-five percent (75%) of the entire board of directors of the combined company.

Until the expiration date, any modification or amendment to, or repeal of, the bylaw provisions implementing the above arrangements will require the affirmative vote of at least seventy-five percent (75%) of the entire board of directors of the combined company.

Following completion of the merger, the combined company will continue to elect all of its directors annually, and, as a result, Mr. Jordan and Mr. Byrd will stand for re-election to the board of directors in each year covered by the applicable provisions of the merger agreement. In addition, the combined company will continue to have a majority voting policy under which an incumbent director who does not receive more “for” votes than “against” votes (including, following completion of the merger, Mr. Jordan and Mr. Byrd) in an uncontested election must tender his or her resignation to the board of directors. The board of directors will then accept, reject or otherwise act with respect to the tendered resignation. If the resignation is not accepted, the director will continue to serve as a member of the board of directors.

In the event that Mr. Jordan or Mr. Byrd does not receive a majority “for” vote in an uncontested election and must submit his resignation, the board of directors could accept the resignation, or not accept the resignation (which would result in Mr. Jordan or Mr. Byrd, as applicable, continuing to serve as a member of the board of directors). In the event that Mr. Jordan or Mr. Byrd is not re-elected in a contested election, the newly-elected board of directors could expand the size of the board of directors (if necessary) and reappoint Mr. Jordan or Mr. Byrd to the board of directors.

Management Team

Immediately following completion of the merger, in addition to the positions held by Mr. Jordan and Mr. Byrd described above, the officers of the combined company and/or the combined bank will include William C. Losch III, as Chief Financial Officer of the combined company and the combined bank, Michael Brown, as President, Regional Banking, of the combined bank, David Popwell, as President, Specialty Banking, of the combined bank, Anthony Restel, as Chief Operating Officer of the combined company and the combined bank, Susan Springfield, as Chief Credit Officer of the combined company and the combined bank, Beth Ardoin, as Chief Communications Officer of the combined company and the combined bank, Vernon H. Stafford, as Chief Audit Executive of the combined company and the combined bank and Terry Akins, as Chief Risk Officer of the combined company and the combined bank.

Lead Director

Immediately following the effective time and until the chairman succession date, the lead director of the board of directors of the combined company and the combined bank will be an independent director chosen by the continuing First Horizon Directors from among the continuing First Horizon directors. Following the chairman succession date and until the third (3 rd) anniversary of the closing date, the lead director will be an independent director chosen by the majority of the continuing IBKC directors from among the continuing IBKC directors, and thereafter will serve in that capacity until replaced by a majority vote of the entire board of directors of the combined company.

Until the expiration date, any modification or amendment to, or repeal of, the bylaw provisions implementing the above arrangements will require the affirmative vote of at least seventy-five percent (75%) of the entire board of directors of the combined company.

Composition of Committees

Immediately following the effective time and until the third (3 rd) anniversary of the closing date, (i) each committee of the boards of directors of the combined company and combined bank will, to the

131

fullest extent practicable, have at least five (5) members, (ii) each committee of the boards of directors of the combined company and combined bank will have a number of continuing IBKC directors that is one (1) less than the number of continuing First Horizon directors serving on each such committee, (iii) the chair of the Compensation Committee will be a director selected from among the continuing IBKC directors by majority vote of the continuing IBKC directors, and (iv) the chair of the Executive and Risk Committee will be (A) until the chairman succession date, a director selected from among the continuing IBKC directors by a majority vote of the continuing IBKC directors, and (B) thereafter, a director selected from among the continuing First Horizon directors by a majority vote of the continuing First Horizon directors.

Until the expiration date, any modification or amendment to, or repeal of, the bylaw provisions implementing the above arrangements will require the affirmative vote of at least seventy-five percent (75%) of the entire board of directors of the combined company.

Headquarters of the Combined Company and the Combined Bank After the Merger

Immediately following the effective time, the headquarters of the combined company and the combined bank will be located in Memphis, Tennessee. Following the effective time and until the expiration date, the headquarters for the combined company’s and the combined bank’s regional banking business will be located in New Orleans, Louisiana.

Until the expiration date, any amendment to the bylaw provisions providing that the combined company’s and the combined bank’s regional banking business will be located in New Orleans, Louisiana will require the affirmative vote of at least seventy-five percent (75%) of the entire board of directors of the combined company.

Commitments to the Community

Prior to the completion of the merger, IBKC will use its reasonable best efforts to establish the First Horizon Louisiana Foundation, focused on community support in Louisiana. The initial members of the board of trustees of the First Horizon Louisiana Foundation will be selected by the IBKC board of directors and the First Horizon board of directors prior to the completion of the merger, with the First Horizon board of directors entitled to select one (1) initial member and the IBKC board of directors entitled to select the remaining initial members. Upon completion of the merger, the combined company will contribute $20 million in cash to the First Horizon Louisiana Foundation.

Accounting Treatment

First Horizon and IBKC prepare their respective financial statements in accordance with GAAP. Although the parties have structured the merger as a merger of equals, GAAP requires that one party to the merger be identified as the acquirer. The merger will be accounted for using the acquisition method of accounting, and First Horizon will be treated as the accounting acquirer. In identifying First Horizon as the acquiring entity for accounting purposes, First Horizon and IBKC took into account a number of factors as of the date of this joint proxy statement/prospectus, including the relative voting rights of all equity instruments in the combined company and the intended corporate governance structure of the combined company. No single factor was the sole determinant in the overall conclusion that First Horizon is the acquirer for accounting purposes; rather all factors were considered in arriving at such conclusion.

Regulatory Approvals

To complete the merger, First Horizon and IBKC need to obtain approvals or consents from, or make filings with, a number of U.S. federal and state bank, antitrust, securities, insurance and other regulatory authorities. Subject to the terms of the merger agreement, First Horizon and IBKC have agreed to cooperate with each other and use reasonable best efforts to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties and governmental entities which are necessary or advisable to consummate the transactions contemplated by the

132

merger agreement (including the merger and the bank merger), and to comply with the terms and conditions of all such permits, consents, approvals and authorizations of all such governmental entities. These approvals include, among others, the approval of the Federal Reserve Board and the TDFI. Under the terms of the merger agreement, neither First Horizon nor IBKC is required to take any action or agree to any condition or restriction in connection with obtaining these approvals that would reasonably be expected to have a material adverse effect on the combined company and its subsidiaries, taken as a whole, after giving effect to the merger.

The approval of an application means only that the regulatory criteria for approval have been satisfied or waived. It does not mean that the approving authority has determined that the consideration to be received by holders of IBKC common stock in the merger is fair. Regulatory approval does not constitute an endorsement or recommendation of the merger.

First Horizon and IBKC believe that the merger does not raise substantial antitrust or other significant regulatory concerns and that they will be able to obtain all requisite regulatory approvals. However, there can be no assurance that all of the regulatory approvals described below will be obtained and, if obtained, there can be no assurances regarding the timing of the approvals, the companies’ ability to obtain the approvals on satisfactory terms or the absence of litigation challenging such approvals. In addition, there can be no assurance that such approvals will not impose conditions or requirements that, individually or in the aggregate, would or could reasonably be expected to have a material adverse effect on the financial condition, results of operations, assets or business of the combined company following completion of the merger. There can likewise be no assurances that U.S. federal or state regulatory authorities will not attempt to challenge the merger or, if such a challenge is made, what the result of such challenge will be.

Federal Reserve Board

The transactions contemplated by the merger agreement are subject to approval by the Federal Reserve Board pursuant to section 3 of the BHC Act with respect to the merger and section 18(c)(2)(B) of the Federal Deposit Insurance Act (the “Bank Merger Act”) with respect to the bank merger. The Federal Reserve Board takes into consideration a number of factors when acting on applications under section 3 of the BHC Act. These factors include the financial and managerial resources (including consideration of the competence, experience and integrity of the officers, directors and principal shareholders, as well as the pro forma capital ratios) and future prospects of the combined organization. The Federal Reserve Board also considers the effectiveness of the applicant in combatting money laundering, the convenience and needs of the communities to be served, as well as the extent to which the proposal would result in greater or more concentrated risks to the stability of the U.S. banking or financial system. The Federal Reserve Board may not approve a proposal that would have significant adverse effects on competition or on the concentration of resources in any banking market. In evaluating an application filed under the Bank Merger Act, the Federal Reserve Board considers: (i) the competitive impact of the transaction; (ii) the financial and managerial resources of the depository institutions party to the bank merger and future prospects of the resulting institution; (iii) the convenience and needs of the communities to be served; (iv) the depository institutions’ effectiveness in combating money-laundering activities; and (v) the risk to the stability of the U.S. banking and financial system.

In considering an application under section 3 of the BHC Act and the Bank Merger Act, the Federal Reserve Board also reviews the records of performance of the relevant insured depository institutions under the Community Reinvestment Act (the “CRA”), pursuant to which the Federal Reserve Board must also take into account the record of performance of each of First Horizon and IBKC in meeting the credit needs of the entire community, including low and moderate income neighborhoods, served by their depository institution subsidiaries. As part of the review process in merger transactions, the Federal Reserve Board frequently receives protests from community groups and others. In their most recent CRA performance evaluation, First Horizon’s subsidiary, First Horizon Bank, received an overall “satisfactory” regulatory rating and IBKC’s wholly owned subsidiary, IBERIABANK, received an overall “satisfactory” regulatory rating, respectively.

133

In addition, in connection with an interstate bank merger transaction, the Federal Reserve Board considers certain additional factors under the Riegle-Neal Act, including state laws regarding the minimum age of the bank to be acquired, the concentration of deposits on a nationwide and statewide basis, and compliance with any applicable state community reinvestment and antitrust laws. Under the Riegle-Neal Act, the Federal Reserve Board may approve an interstate merger transaction only if each constituent bank is adequately capitalized at the time the application for such transaction is filed with the Federal Reserve Board, and the Federal Reserve Board determines that the resulting bank will be well capitalized and well managed upon the consummation of the transaction.

The initial filing of the applications to the Federal Reserve Board occurred on December 18, 2019.

TDFI

Certain of the transactions contemplated by the merger agreement are subject to approval by the TDFI under Section 0180-15-.03 of the Tennessee Rules and Regulations, and the bank merger agreement is subject to approval by the TDFI under Section 45-2-1304 of the Tennessee Code. In evaluating a merger agreement between stock-form banking organizations, the TDFI considers: (i) whether the resulting state bank meets the requirements of state law as to the formation of a new state bank; (ii) whether the agreement provides an adequate capital structure, including surplus, in relation to the deposit liabilities of the resulting state bank and its other activities that are to continue or are to be undertaken; (iii) whether the agreement is fair; and (iv) whether or not the merger is contrary to the public interest.

The TDFI approved the bank merger and expressed its non-objection to the merger on January 27, 2020.

Public Notice and Comments

Furthermore, the BHC Act and the Bank Merger Act require published notice of, and the opportunity for public comment on, the applications to the Federal Reserve Board. The Federal Reserve Board takes into account the views of third-party commenters, particularly on the subject of the merging parties’ CRA performance and record of service to their communities. The Federal Reserve Board is also authorized to hold one or more public hearings or meetings if it determines that such hearings or meetings would be appropriate. The receipt of written comments or any public meeting or hearing could prolong the period during which the applicable application is under review by the Federal Reserve Board.

Waiting Periods

In addition to the Federal Reserve Board, the Antitrust Division of the Department of Justice (the “DOJ”) conducts a concurrent competitive review of the merger to analyze the merger’s competitive effects and determine whether the merger would result in a violation of the antitrust laws. Transactions approved under section 3 of the BHC Act or the Bank Merger Act generally may not be completed until thirty (30) days after the approval of the applicable federal agency is received, during which time the DOJ may challenge the transaction on antitrust grounds. With the approval of the applicable federal agency and the concurrence of the DOJ, the waiting period may be reduced to no less than fifteen (15) days. The commencement of an antitrust action would stay the effectiveness of such an approval unless a court specifically ordered otherwise. In reviewing the merger, the DOJ could analyze the merger’s effect on competition differently than the Federal Reserve Board, and, thus, it is possible that the DOJ could reach a different conclusion than the Federal Reserve Board regarding the merger’s effects on competition. A determination by the DOJ not to object to the merger may not prevent the filing of antitrust actions by private persons or state attorneys general. There can be no assurance if and when DOJ clearance will be obtained, or as to the conditions or limitations that such DOJ approval may contain or impose.

134

Additional Regulatory Approvals and Notices

Notifications and/or applications requesting approval may be submitted to various other federal and state regulatory authorities and self-regulatory organizations, including certain state insurance departments.

Treatment of IBKC Preferred Stock and IBKC Depositary Shares

In the merger, each share of IBKC series B preferred stock, IBKC series C preferred stock and IBKC series D preferred stock, in each case issued and outstanding immediately prior to the effective time and excluding dissenting shares, will be converted into the right to receive one (1) share of First Horizon series B preferred stock, First Horizon series C preferred stock and First Horizon series D preferred stock, respectively. The rollover First Horizon preferred stock will have terms that are the same as the terms of the applicable series of outstanding IBKC preferred stock, taking into account that IBKC will not be the surviving entity in the merger and, with respect to the IBKC series B preferred stock, taking into account that the optional redemption date for the First Horizon series B preferred stock may be deferred until the first dividend payment date that is at least five (5) years from the closing date.

Each outstanding share of IBKC series B preferred stock, IBKC series C preferred stock and IBKC series D preferred is presently represented by IBKC depositary shares that represent a 1/400th ownership interest in a share of the applicable series of IBKC preferred stock. Upon completion of the merger, First Horizon will assume the obligations of IBKC under the applicable deposit agreements. Each IBKC depositary share (other than in respect of dissenting shares of IBKC preferred stock) will then become a rollover First Horizon depositary share and thereafter represent shares of rollover First Horizon depository preferred stock.

Stock Exchange Listings

First Horizon common stock is listed for trading on the NYSE under the symbol “FHN,” and IBKC common stock is listed on NASDAQ under the symbol “IBKC.” In the merger, the IBKC common stock currently listed on the NASDAQ will be delisted from such exchange and deregistered under the Exchange Act.

Under the terms of the merger agreement, First Horizon will cause the shares of First Horizon common stock to be issued in the merger to be approved for listing on the NYSE, subject to official notice of issuance, and the merger agreement provides that neither First Horizon nor IBKC will be required to complete the merger if such shares are not authorized for listing on the NYSE, subject to notice of issuance. Following the merger, shares of First Horizon common stock will continue to be traded on the NYSE.

The IBKC depositary shares representing a 1/400th interest in a share of IBKC series B preferred stock, series C preferred stock and series D preferred stock are currently listed on the NASDAQ under the symbol “IBKCP,” “IBKCO” and “IBKCN,” respectively. The rollover First Horizon depositary shares are expected to be listed on the NYSE upon completion of the merger.

Appraisal or Dissenters’ Rights in the Merger

Holders of First Horizon Common Stock

Under Section 48-23-102 of the TBCA, the holders of First Horizon common stock will not be entitled to dissenters’ rights in connection with the merger with respect to shares of any class or series that remain outstanding after completion of the merger. If the merger is completed, holders of First Horizon common stock will not receive any consideration, and their shares of First Horizon common stock will remain outstanding and will constitute shares of the combined company. Accordingly, holders of First Horizon common stock are not entitled to any dissenters’ rights in connection with the merger.

135

Holders of IBKC Common Stock

Under Part 13 of the LBCA, the holders of IBKC common stock will not be entitled to appraisal rights in connection with the merger if, on the record date for the IBKC special meeting, IBKC’s shares are traded in an organized market that has at least two thousand (2,000) shareholders and a market value of at least $20 million. IBKC common stock is currently listed on the NASDAQ, a national securities exchange, and is expected to continue to be so listed on the record date for the IBKC special meeting. Accordingly, the holders of IBKC common stock are not entitled to any appraisal rights in connection with the merger.

Holders of IBKC Preferred Stock

The IBKC depositary shares are not a class or series of shares issued by IBKC and thus appraisal rights under Part 13 of the LBCA do not independently apply to the depositary shares. Accordingly, to direct the depository to exercise appraisal rights with respect to the IBKC preferred stock, holders of depositary shares will be required to follow the procedures provided by the depository with respect thereto and in accordance with requirements of Louisiana law.

If you hold IBKC depositary shares and you wish to exercise appraisal rights in respect of the merger, IBKC requests that you complete the form of instruction to be provided to you (in accordance with the instructions set out on the form) and return it to your bank, broker or other nominee, as applicable, to direct the depository to exercise appraisal rights on your behalf following their usual procedures.

The following discussion is not a complete description of appraisal rights available to holders of IBKC preferred stock under Louisiana law. This description is qualified in its entirety by the full text of the relevant provision of the LBCA, which is reprinted in its entirety as Annex E to this joint proxy statement/prospectus. If you desire to exercise your appraisal rights, you should review carefully the LBCA and are urged to consult a legal advisor before electing or attempting to exercise these rights.

Holders of IBKC preferred stock have a right to demand payment in cash of the “fair value” of their shares, as that term is defined in the LBCA. Shareholders who receive a fair value cash payment will not be entitled to receive any shares of rollover First Horizon preferred stock. Part 13 of the LBCA sets forth the rights of IBKC preferred shareholders who wish to demand appraisal for their shares. The following is a summary of the material terms of the statutory procedures to be followed by a holder of IBKC preferred stock in order to perfect appraisal rights under the LBCA. Shareholders who do not properly follow appraisal rights procedures will receive the merger consideration provided under the merger agreement if the merger is effected. A copy of Part 13 of the LBCA is attached as Annex E to this joint proxy statement/prospectus.

Requirements of Appraisal Rights

If an IBKC preferred shareholder elects to exercise the right to demand appraisal, such shareholder must satisfy all of the following conditions:

| • |  | The shareholder must deliver to IBKC, before the vote on approval or disapproval of the IBKC merger proposal is taken, written notice of the shareholder’s intent to demand payment if the merger is effectuated. This notice must be in addition to and separate from any proxy or vote against the IBKC merger proposal. Neither voting against, abstaining from voting, nor failing to vote on the IBKC merger proposal will constitute a notice within the meaning of Part 13.
| • |  | The preferred shareholder must not vote, or cause or permit to be voted, any shares in favor of the plan of merger. A failure to vote will satisfy this requirement, as will a vote against the plan of merger, but a vote in favor of the plan of merger, by proxy or in person, or the return of a signed proxy which does not specify a vote against approval of the plan of merger or contain a direction to abstain, will constitute a waiver of the preferred shareholder’s appraisal rights.

136

If the requirements above are not satisfied and the merger becomes effective, an IBKC preferred shareholder will not be entitled to payment for such shareholder’s shares under the provisions of Part 13.

Required Notice to IBKC

Written notices of intent to demand appraisal should be addressed to IBERIABANK Corporation, 200 West Congress Street, Lafayette, Louisiana 70501, Attention: Corporate Secretary. The notice should be executed by the holder of record of shares of IBKC preferred stock.

Appraisal Notice from Surviving Corporation

If the merger becomes effective, the surviving corporation will be required to deliver a written appraisal notice and form to all preferred shareholders who have satisfied the requirements described above. The appraisal notice and form must be sent no earlier than the effective date of the merger and no later than 10 days after such effective date. The appraisal notice must include:

| • |  | a form requiring a preferred shareholder asserting appraisal rights to certify that the shareholder did not vote for or consent to the merger;
| • |  | a statement of where the form must be sent;
| • |  | a statement of the date by which the surviving corporation must receive the form, which date may not be fewer than 40 nor more than 60 days after the date the appraisal notice and form are sent. The form must also state that the preferred shareholder will have waived the right to demand appraisal with respect to the shares unless the form is received by the surviving corporation by the demand deadline;
| • |  | the surviving corporation’s estimate of the fair value of the preferred shareholder’s shares;
| • |  | a statement that, if requested in writing, the surviving corporation will provide to the shareholder so requesting, within 10 days after the date the appraisal notice and form are sent, the number of preferred shareholders who return the forms by the specified date and the total number of shares owned by them;
| • |  | a statement of the date by which the notice to withdraw from the appraisal process must be received, which date must be within 20 days after the demand deadline;
| • |  | a statement specifying the first date of any announcement to shareholders, made prior to the date the merger became effective, of the principal terms of the merger, and if such an announcement was made, the form must require a preferred shareholder asserting appraisal rights to certify whether beneficial ownership of those shares for which appraisal rights are asserted was acquired before that date; and
| • |  | a copy of Part 13 of the LBCA.

A preferred shareholder who receives an appraisal notice from the surviving corporation must demand payment by signing and returning the appraisal form included with the notice. Preferred shareholders should respond to the appraisal form’s request discussed above regarding when beneficial ownership of the shares was acquired. A failure to provide this certification allows the surviving corporation to treat the shares as “after-acquired shares” subject to the surviving corporation’s authority to delay payment as described below. Once a preferred shareholder returns the signed appraisal form, the shareholder loses all rights as a shareholder unless a timely withdrawal occurs as described below. A preferred shareholder who does not sign and return the appraisal form is not entitled to payment under Part 13 of the LBCA and will receive the merger consideration.

A preferred shareholder who has complied with all the steps required for appraisal may thereafter decline to exercise appraisal rights and withdraw from the appraisal process by notifying the surviving corporation in writing. The appraisal notice will include a date by which the withdrawal

137

notice must be received. Following this date, a preferred shareholder may only withdraw from the appraisal process with the surviving corporation’s consent. A preferred shareholder who withdraws from the appraisal process will receive the merger consideration.

Surviving Corporation’s Payment to Dissenting Preferred Shareholders

Within 30 days after the deadline for making a demand for appraisal rights, the surviving corporation from the merger is required to pay each preferred shareholder the amount that the surviving corporation estimates to be the fair value of such shareholder’s shares, plus interest accrued from the effective date of the merger to the date of payment. The payment must be accompanied by the following:

| • |  | IBKC’s most recently available balance sheet, income statement, and statement of cash flows as of the end of or for the fiscal year ending not more than 16 months before the date of payment, and the latest available quarterly financial statements, if any;
| • |  | a statement of the surviving corporation’s estimate of the fair value of the preferred shares, which must equal or exceed the estimate in the earlier-provided appraisal notice; and
| • |  | a statement that the preferred shareholder has the right to submit a final payment demand as described below and that, if the shareholder does not submit a final payment demand within the specified time frame, the shareholder will (i) lose the right to submit a final payment demand and (ii) be deemed to have accepted the provided payment in full satisfaction of the surviving corporation’s obligations under Part 13 of the LBCA.

Final Payment Demand by Dissatisfied Preferred Shareholders

A preferred shareholder who is dissatisfied with the amount of the payment received from the surviving corporation may notify the surviving corporation in writing of such preferred shareholder’s own estimate of the fair value of the shares and the amount of interest due, and demand payment of the excess of this estimate over the amount previously paid by the surviving corporation. A shareholder who does not submit a final payment demand within 30 days after receiving payment from the surviving corporation is only entitled to the amount previously paid by the surviving corporation.

After-Acquired Shares

The surviving corporation may withhold payment with respect to any preferred shares which a preferred shareholder failed to certify on the appraisal form as being beneficially owned prior to the date stated in the appraisal notice as the date on which the principal terms of the merger were first announced. If the surviving corporation withholds payment, it must, within 30 days after the demand deadline, provide affected preferred shareholders with IBKC’s most recently available balance sheet, income statement, and statement of cash flows as of the end of or for the fiscal year ending not more than 16 months before the date of payment, and the latest available quarterly financial statements, if any. The surviving corporation must also inform such shareholders that they may accept the surviving corporation’s estimate of the fair value of their shares, plus interest, in full satisfaction of their claim or submit a final payment demand. Preferred shareholders who wish to accept the offer must notify the surviving corporation of their acceptance within 30 days after receiving the offer. The surviving corporation must send payment to such shareholders within 10 days after receiving their acceptance. Preferred shareholders who are dissatisfied with the offer must reject the offer and demand payment of the shareholder’s own estimate of the fair value of the shares, plus interest. If a preferred shareholder does not explicitly accept or reject the surviving corporation’s offer, the shareholder will be deemed to have accepted the offer. The surviving corporation must send payment to these preferred shareholders within 40 days after sending the notice regarding withholding of payment.

138

Judicial Appraisal of Shares

If the surviving corporation does not pay the amount demanded pursuant to a preferred shareholder’s final payment demand, the surviving corporation must commence a proceeding in the district court in Lafayette Parish within 60 days after receiving the final demand. The purpose of the proceeding is to determine the fair value of the shares and the interest due. If the surviving corporation does not commence the proceeding within the 60-day period, it must pay each shareholder demanding appraisal the amount demanded, plus interest.

All preferred shareholders whose payment demands remain unsettled will be parties to the action. Each preferred shareholder who is a party to the proceeding will be entitled to judgment for the amount, if any, by which the court finds the fair value of the shareholder’s shares, plus interest, exceeds the amount paid by the surviving corporation to the shareholder for the shares.

The court will determine all court costs of the proceeding and will assess the costs against the surviving corporation, except that the court may assess costs against some or all of the preferred shareholders demanding appraisal, in amounts the court finds equitable, to the extent the court finds such preferred shareholders acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by Part 13. The court may also assess expenses (including legal fees) for the respective parties, in the amounts the court finds equitable (i) against the surviving corporation if the court finds that it did not comply with the statutes or (ii) against the surviving corporation or the shareholder demanding appraisal, if the court finds that the party against whom expenses are assessed acted arbitrarily, vexatiously, or not in good faith. If the court finds that the expenses incurred by any preferred shareholder were of substantial benefit to other shareholders similarly situated and that the expenses should not be assessed against the surviving corporation, it may direct that the expenses be paid out of the amounts awarded to the preferred shareholders who were benefited.

If the surviving corporation fails to make a required payment to a preferred shareholder under Part 13, the shareholder entitled to payment can commence an action against the surviving corporation directly for the amount owed and recover the expenses of that action. A preferred shareholder’s right to enforce the surviving corporation’s payment obligation is preempted five years after the date that the corporation’s payment to the preferred shareholder becomes due under Part 13.

If you do not follow the prescribed procedures, you will not be entitled to appraisal rights with respect to your shares of IBKC preferred stock. Because of the complexity of the procedures necessary to exercise appraisal rights, any IBKC preferred shareholder wishing to exercise the right to appraisal should consult with a legal advisor.

Litigation Relating to the Merger

Following the public announcement of the merger agreement, purported stockholders of IBKC filed a putative class action lawsuit and three individual lawsuits against IBKC, the members of the IBKC board of directors, and in the case of the putative class action, against First Horizon. Two of the individual lawsuits were filed in the United States District Court for the Eastern District of New York (Hertz v. IBERIABANK et al., No. 1:20-cv-00267 (filed Jan. 16, 2020); Cooksey v. IBERIABANK et al., No. 1:20-cv-00431 (filed Jan. 26, 2020)) and the third was filed in the United States District Court for the Southern District of New York, (Wang v. IBERIABANK, et al., No. 1:20-cv-00105 (filed on Jan. 6, 2020)). The putative class action was filed in the United States District Court for the District of Delaware (Parshall v. IBERIABANK et al., No. 1:20-cv-00027 (Jan. 8, 2020)). The complaints contain similar allegations contending, among other things, that the registration statement on Form S-4 misstated or failed to disclose certain allegedly material information in violation of federal securities laws. The complaints seek injunctive relief enjoining the merger, attorneys and experts’ fees, and other remedies.

The outcome of the pending and any additional future litigation is uncertain. If any case is not resolved, the lawsuit(s) could prevent or delay completion of the merger and result in substantial costs to First Horizon and IBC, including any costs associated with the indemnification of directors

139

and officers. One of the conditions to the closing of the merger is that no order, injunction or decree issued by any court or agency of competent jurisdiction or other legal restraint or prohibition preventing the consummation of the merger or the bank merger shall be in effect. As such, if plaintiffs are successful in obtaining an injunction prohibiting the completion of the merger or the bank merger on the agreed-upon terms, then such injunction may prevent the merger from being completed, or from being completed within the expected timeframe. The defense or settlement of any lawsuit or claim that remains unresolved at the time the merger is completed may adversely affect the combined company’s business, financial condition, results of operations and cash flows.

THE MERGER AGREEMENT

This section of the joint proxy statement/prospectus describes the material terms of the merger agreement. The description in this section and elsewhere in this joint proxy statement/prospectus is subject to, and qualified in its entirety by reference to, the complete text of the merger agreement, which is attached as Annex A to this document and incorporated by reference herein. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. We urge you to read the full text of the merger agreement, as it is the legal document governing the merger. This section is not intended to provide you with any factual information about First Horizon or IBKC. Such information can be found elsewhere in this joint proxy statement/prospectus and in the public filings First Horizon and IBKC make with the SEC, as described in the section entitled “Where You Can Find More Information” beginning on page 218 of this joint proxy statement/prospectus.

Explanatory Note Regarding the Merger Agreement

The merger agreement and this summary of terms are included to provide you with information regarding the terms of the merger agreement. Factual disclosures about First Horizon and IBKC contained in this joint proxy statement/prospectus or in the public reports of First Horizon or IBKC filed with the SEC may supplement, update or modify the factual disclosures about First Horizon and IBKC contained in the merger agreement. The merger agreement contains representations and warranties by First Horizon, on the one hand, and by IBKC, on the other hand, made solely for the benefit of the other. The representations, warranties and covenants made in the merger agreement by First Horizon and IBKC were qualified and subject to important limitations agreed to by First Horizon and IBKC in connection with negotiating the terms of the merger agreement. In particular, in your review of the representations and warranties contained in the merger agreement and described in this summary, it is important to bear in mind that the representations and warranties were negotiated with the principal purpose of establishing circumstances in which a party to the merger agreement may have the right not to consummate the merger if the representations and warranties of the other party prove to be untrue due to a change in circumstance or otherwise, and allocating risk between the parties to the merger agreement, rather than establishing matters as facts. The representations and warranties also may be subject to a contractual standard of materiality different from that generally applicable to shareholders and reports and documents filed with the SEC, and some were qualified by the matters contained in the confidential disclosure schedules that First Horizon and IBKC each delivered in connection with the merger agreement and certain documents filed with the SEC. Moreover, information concerning the subject matter of the representations and warranties, which do not purport to be accurate as of the date of this joint proxy statement/prospectus, may have changed since the date of the merger agreement. Accordingly, the representations and warranties in the merger agreement should not be relied on by any persons as characterizations of the actual state of facts about First Horizon and IBKC at the time they were made or otherwise.

Structure of the Merger

Each of First Horizon’s and IBKC’s respective boards of directors has unanimously approved and adopted the merger agreement. The merger agreement provides for the merger of IBKC with and into First Horizon, with First Horizon continuing as the surviving entity in a merger of equals. Following the completion of the merger, IBERIABANK, a subsidiary of IBKC, will merge with and into First Horizon Bank, a subsidiary of First Horizon, with First Horizon Bank as the surviving bank in the bank merger.

Prior to the completion of the merger, First Horizon and IBKC may, by mutual agreement, change the method or structure of effecting the combination of First Horizon and IBKC, except that no such change may (1) alter or change the exchange ratio or the number of shares of First Horizon common stock received by holders of IBKC common stock in exchange for each share of IBKC common stock, (2) adversely affect the tax treatment of holders of IBKC common stock or holders

141

of First Horizon common stock, (3) adversely affect the tax treatment of IBKC or First Horizon or (4) materially impede or delay the consummation of the transactions contemplated by the merger agreement in a timely manner.

Merger Consideration

Each share of IBKC common stock issued and outstanding immediately prior to the effective time, except for shares of IBKC common stock held by IBKC or First Horizon (in each case other than shares of IBKC common stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in an fiduciary or agency capacity that are beneficially owned by third parties or (ii) held directly or indirectly by IBKC or First Horizon in respect of debts previously contracted), will be converted into the right to receive 4.584 shares of First Horizon common stock.

If the outstanding shares of IBKC common stock or First Horizon common stock is increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split, or other similar change in capitalization, or there is any extraordinary dividend or distribution, an appropriate and proportionate adjustment will be made to the exchange ratio to give First Horizon and the holders of IBKC common stock the same economic effect as contemplated by the merger agreement prior to such event.

Also in the merger, each share of IBKC preferred stock issued and outstanding immediately prior to the effective time (other than dissenting shares) will be converted into the right to receive one (1) share of an applicable newly issued series of rollover First Horizon preferred stock with the same terms as the outstanding IBKC preferred stock.

Fractional Shares

First Horizon will not issue any fractional shares of First Horizon common stock in the merger. Instead, a former holder of IBKC common stock who otherwise would have received a fraction of a share of First Horizon common stock will receive an amount in cash rounded to the nearest whole cent. This cash amount will be determined by multiplying the fraction of a share (after taking into account all shares of IBKC common stock held by such holder immediately prior to the effective time and rounded to the nearest thousandth when expressed in decimal form) of First Horizon common stock to which the holder would otherwise be entitled by the average closing-sale price per share of First Horizon common stock for the consecutive period of five (5) trading days ending on the day preceding the closing date.

Governing Documents

At the effective time, the First Horizon charter, as amended by the First Horizon charter amendment, will be the charter of the combined company, and the bylaws of First Horizon, as amended by the First Horizon bylaw amendment, will be the bylaws of the combined company.

Treatment of IBKC Equity Awards

IBKC Stock Options.

At the effective time, each outstanding option to purchase shares of IBKC common stock (an “IBKC stock option”) that was granted prior to November 3, 2019 will accelerate in full and be converted into an option (a “First Horizon stock option”) to purchase (i) a number of shares of First Horizon common stock (rounded down to the nearest whole share) equal to the product of (A) the total number of shares of IBKC common stock subject to such IBKC stock option immediately prior to the effective time multiplied by (B) the exchange ratio, (ii) at an exercise price per share of First Horizon common stock (rounded up to the nearest whole cent) equal to the quotient of (A) the exercise price per share of IBKC common stock of such IBKC stock option immediately prior to

142

the effective time divided by (B) the exchange ratio (as it may be adjusted as set forth in the merger agreement), with each such First Horizon stock option subject to the same terms and conditions, including exercisability and forfeiture terms, as applied to the corresponding IBKC stock option immediately prior to the effective time, except as expressly set forth in the merger agreement.

IBKC Restricted Stock Awards.

At the effective time, each outstanding IBKC restricted stock award that was granted prior to November 3, 2019 will accelerate in full and be cancelled and will only entitle the holder to receive immediately following the effective time, a number of shares of First Horizon common stock equal to the product of (i) the total number of shares of IBKC common stock subject to such IBKC restricted stock award immediately prior to the effective time multiplied by (ii) the exchange ratio, less applicable taxes required to be withheld with respect to such vesting.

IBKC PSU Awards.

At the effective time, each outstanding IBKC PSU award that was granted prior to November 3, 2019 will accelerate in full and be cancelled and will only entitle the holder to receive (without interest), immediately following the effective time, a number of shares of First Horizon common stock (less applicable taxes required to be withheld with respect to such vesting) equal to (i) the number of shares of IBKC common stock subject to such IBKC PSU award immediately prior to the effective time (including any applicable dividend equivalents) based on the greater of (A) the target performance level or (B) the actual performance level through September 30, 2019 as reasonably determined by the compensation committee of the board of directors of IBKC, multiplied by (ii) the exchange ratio; provided that, with respect to any IBKC PSU award that constitutes nonqualified deferred compensation subject to Section 409A of the Code and that is not permitted to be paid at the effective time without triggering a tax or penalty under Section 409A of the Code, such payment will be made at the earliest time permitted under the applicable IBKC equity incentive plan and award agreement that will not trigger a tax or penalty under Section 409A of the Code.

IBKC Phantom Stock Awards.

At the effective time, each outstanding IBKC phantom stock award that was granted prior to November 3, 2019 will vest and be cancelled and automatically entitle the holder of such IBKC phantom stock award to receive (without interest), on the first regularly scheduled payroll date of First Horizon following the closing date, an amount in cash (rounded to the nearest cent and less applicable taxes required to be withheld with respect to such vesting) determined by multiplying (i) the closing price of one share of First Horizon common stock on the closing date by (ii) the number of shares of First Horizon common stock underlying such IBKC phantom stock award (as determined by multiplying (A) the number of shares of IBKC common stock (including any applicable dividend equivalents) underlying such IBKC phantom stock award by (B) the exchange ratio (the “phantom stock consideration”); provided that, to the extent a holder of IBKC phantom stock awards has made a deferral election in respect of payments pursuant to such IBKC phantom stock awards, the applicable portion of the phantom stock consideration will be credited to such holder’s deferred compensation account under IBKC’s Executive Nonqualified Excess Plan.

Future Grants of Equity Awards.

At the effective time, each IBKC equity award granted on or after the date of the merger agreement and not in violation of the merger agreement that expressly provides for treatment in connection with the occurrence of the effective time that is different from the treatment prescribed in the merger agreement as set forth above, or as mutually agreed by the parties and a holder of any IBKC equity award, will be converted into an equity award denominated in shares of First

143

Horizon common stock (rounded down to the nearest whole number) (a “converted equity award”) equal to the product of (i) the number of shares of IBKC common stock subject to such IBKC equity award immediately prior to the effective time multiplied by (ii) the exchange ratio; provided, that to the extent any such converted equity award is a IBKC stock option (a “converted stock option”), the exercise price per share of such converted stock option will be equal to the quotient (rounded up to the nearest whole cent) of (A) the exercise price per share of IBKC common stock of such IBKC stock option immediately prior to the effective time divided by (B) the exchange ratio. Notwithstanding the above, any IBKC equity awards granted on or after November 3, 2019 and prior to the closing date will not provide for automatic “single-trigger” acceleration of vesting or payment at the effective time, but may instead provide for “double-trigger” vesting upon a termination without “cause” or for “good reason” following the effective time.

Closing and Effective Time of the Merger

The merger will become effective at such time specified in the articles of merger to be filed with the Tennessee Secretary and the articles of merger to be filed with the Louisiana Secretary, or at such other time provided by applicable law. The closing will occur at 10:00 a.m., New York City time on a date no later than three (3) business days after the satisfaction or waiver (subject to applicable law) of the conditions set forth in the merger agreement (other than those conditions that by their nature can only be satisfied at the closing, but subject to the satisfaction or waiver of such conditions), unless another date, time or place is agreed to in writing by IBKC and First Horizon.

Conversion of Shares; Exchange of IBKC Stock Certificates

Letter of Transmittal

As promptly as practicable after the effective time, and in any event within five (5) days thereafter, First Horizon and IBKC will cause the exchange agent to mail to each holder of record of IBKC common stock or IBKC preferred stock immediately prior to the effective time a letter of transmittal and instructions for use in surrendering shares of IBKC common stock or IBKC preferred stock, as applicable, in exchange for the consideration the holder is entitled to receive under the merger agreement.

If a certificate for IBKC common stock or IBKC preferred stock has been lost, stolen or destroyed, the exchange agent will issue the consideration in the merger upon receipt of (1) an affidavit of that fact by the claimant and (2) if required by First Horizon or the exchange agent, the posting of a bond in an amount as First Horizon or the exchange agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such certificate.

After the effective time, there will be no further transfers on the stock transfer books of IBKC of IBKC common stock or IBKC preferred stock that were issued and outstanding immediately prior to the effective time.

Withholding

First Horizon will be entitled to deduct and withhold, or cause the exchange agent to deduct and withhold, from any cash portion of the merger consideration, cash in lieu of fractional shares or any other cash amounts payable under the merger agreement to any holder of IBKC common stock or IBKC preferred stock the amounts it is required to deduct and withhold under the Code or any provision of state, local, or foreign tax law. If any such amounts are withheld and paid over to the appropriate governmental authority, such amounts will be treated for all purposes of the merger agreement as having been paid to the holder from whom they were withheld.

144

Dividends and Distributions

No dividends or other distributions declared with respect to First Horizon common stock or rollover First Horizon preferred stock will be paid to the holder of any unsurrendered certificates of IBKC common stock or IBKC preferred stock, as applicable, until the holder surrenders such certificate in accordance with the merger agreement. After the surrender of a certificate in accordance with the merger agreement, the record holder thereof will be entitled to receive any such dividends or other distributions, without any interest, which had previously become payable with respect to the whole shares of First Horizon common stock or rollover First Horizon preferred stock which the shares of IBKC common stock or IBKC preferred stock, as applicable, represented by such certificate have been converted into the right to receive under the merger agreement.

Certain representations and warranties of First Horizon and IBKC are qualified as to “materiality” or “material adverse effect.” For purposes of the merger agreement, a “material adverse effect,” when used in reference to either IBKC, First Horizon or the combined company, means any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (1) the business, properties, assets, liabilities, results of operations or financial condition of such party and its subsidiaries taken as a whole or (2) the ability of such party to timely consummate the transactions contemplated by the merger agreement.

However, with respect to clause (1), a material adverse effect will not be deemed to include the impact of:

| • |  | changes, after the date of the merger agreement, in U.S. generally accepted accounting principles or applicable regulatory accounting requirements;
| • |  | changes, after the date of the merger agreement, in laws, rules or regulations of general applicability to companies in the industries in which such party and its subsidiaries operate, or interpretations thereof by courts or governmental entities;

| • |  | a decline in the trading price of a party’s common stock or the failure, in and of itself, to meet earnings projections or internal financial forecasts (provided that the underlying causes of such decline or failure may be taken into account in determining whether a material adverse effect has occurred);

except, with respect to the first, second and third bullets described above, to the extent that the effects of such change are materially disproportionately adverse to the business, properties, assets, liabilities, results of operations or financial condition of such party and its subsidiaries, taken as a whole, as compared to other companies in the industry in which such party and its subsidiaries operate.

The representations and warranties in the merger agreement do not survive the effective time.

146

Regulatory Matters

First Horizon and IBKC have agreed to cooperate with each other and use their respective reasonable best efforts to prepare and file all necessary documentation, to effect all applications, notices, petitions and filings, (and in the case of the applications, notices, petitions and filings in respect of the requisite regulatory approvals, use their reasonable best efforts to make such filings within forty-five (45) days of the date of the merger agreement), to obtain as promptly as practicable all permits, consents, approvals and authorizations of all third parties, regulatory agencies and governmental entities which are necessary or advisable to consummate the transactions contemplated by the merger agreement, and to comply with the terms and conditions of all such

149

permits, consents, approvals and authorizations of all such regulatory agencies and governmental entities. Each of First Horizon and IBKC has agreed to use its reasonable best efforts to resolve any objection that may be asserted by any governmental entity with respect to the merger agreement or the transactions contemplated by the merger agreement. However, in no event will First Horizon or IBKC or any of their respective subsidiaries be required, and in no event will First Horizon or IBKC or any of their respective subsidiaries be permitted (without the written consent of the other party), to take any action, or commit to take any action, or agree to any condition or restriction, in connection with obtaining the required permits, consents, approvals and authorizations of governmental entities that would reasonably be expected to have a material adverse effect on the combined company and its subsidiaries, taken as a whole, after giving effect to the merger. First Horizon and IBKC have also agreed to furnish each other with all information reasonably necessary or advisable in connection with any statement, filing, notice or application to any governmental entity in connection with the merger, as well as to keep each other apprised of the status of matters related to the completion of the transactions contemplated by the merger agreement. First Horizon and IBKC have further agreed to promptly advise the other party with respect to substantive matters that are addressed in any meeting or conference with any governmental entity in connection with or affecting the transactions contemplated by the merger agreement which the other party does not attend or participate in, to the extent permitted by such governmental entity and subject to applicable law and the merger agreement.

Employee Matters

From and after the effective time, unless otherwise mutually determined by IBKC and First Horizon prior to the effective time, First Horizon will provide generally to employees of IBKC and its subsidiaries who at the effective time become employees of First Horizon or its subsidiaries (the “continuing employees”), employee compensation and benefits under the First Horizon benefit plans on terms and conditions that are substantially comparable in the aggregate as those that apply to similarly situated First Horizon employees. Notwithstanding the foregoing, First Horizon and IBKC agree that, during the period commencing at the effective time and ending on the eighteen (18)-month anniversary thereof, any continuing employee of First Horizon, IBKC or any of their respective subsidiaries who is involuntarily terminated during such eighteen (18)-month period will be provided with severance benefits as described in Section 6.6(a) of the First Horizon disclosure schedule.

For purposes of eligibility, participation, vesting and benefit accrual (except not for purposes of benefit accrual under any defined benefit pension plan or to the extent that such credit would result in a duplication of benefits) under the First Horizon benefit plans and the IBKC benefit plans, service with or credited by First Horizon, IBKC or any of their respective subsidiaries or predecessors for continuing employees or continuing employees of First Horizon or its subsidiaries will be treated as service with First Horizon to the same extent that such service was taken into account under the analogous IBKC benefit plan or First Horizon benefit plan prior to the effective time. Additionally, with respect to any IBKC benefit plan or First Horizon benefit plan in which any employees of First Horizon or IBKC (or their subsidiaries) prior to the effective time first become eligible to participate on or after the effective time, and in which such employees did not participate prior to the effective time, each party will: (i) waive all preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous First Horizon benefit plan or IBKC benefit plan, as the case may be, and (ii) provide each such employee and his or her eligible dependents with credit for any co-payments and deductibles paid prior to the effective time under a First Horizon benefit plan or IBKC benefit plan (to the same extent that such credit was given under the analogous IBKC or First Horizon benefit plan) in satisfying any applicable deductible or out-of-pocket requirements under any IBKC benefit plan or First Horizon benefit plan in which such employee first become eligible to participate after the effective time.

150

The combined company agrees to honor in accordance with their terms all First Horizon benefit plans and IBKC benefit plans. IBKC and First Horizon agree that the transactions contemplated by the merger agreement shall constitute a “change in control,” “change of control” or other similar concept under any IBKC benefit plan, and prior to the effective time the board of directors of IBKC shall be empowered to take such action as necessary to declare such status under such plans.

Director and Officer Indemnification and Insurance

The merger agreement provides that after the effective time, the combined company will indemnify and hold harmless all present and former directors, officers and employees of IBKC and its subsidiaries against, and will advance expenses as incurred to such persons in respect of, all costs and liabilities arising out of the fact that such person is or was a director, officer or employee of IBKC or its subsidiaries and pertaining to matters existing or occurring at or prior to the effective time, in each case to the extent permitted by applicable law, the IBKC articles, the IBKC bylaws and the governing or organizational documents of any subsidiary of IBKC; provided, that in the case of advancement of expenses, any such person provides an undertaking to repay such advances if it is ultimately determined that such person is not entitled to indemnification. All rights to indemnification as provided in any indemnification agreement in existence on the date of the merger will survive the merger and be honored by the combined company.

The merger agreement requires the combined company to maintain for a period of six (6) years after consummation of the merger IBKC’s existing directors’ and officers’ liability insurance policy, or policies with a substantially comparable insurer of at least the same coverage and amounts and containing terms and conditions that are no less advantageous to the insured, with respect to claims arising from facts or events that occurred at or prior to the consummation of the merger. However, the combined company is not required to spend annually more than three hundred percent (300%) of the current annual premium paid as of the date of the merger agreement by IBKC for such insurance (the “premium cap”), and if such premiums for such insurance would at any time exceed that amount, then the combined company will maintain policies of insurance which, in its good faith determination, provide the maximum coverage available at an annual premium equal to the premium cap. In lieu of the foregoing, First Horizon or IBKC, in consultation with, but only upon the consent of First Horizon, may (and at the request of First Horizon, IBKC will use its reasonable best efforts to) obtain at or prior to the effective time a six (6)-year “tail” policy under IBKC’s existing directors and officers insurance policy providing equivalent coverage to that described in the preceding sentence if such a policy can be obtained for an amount that, in the aggregate, does not exceed the premium cap.

Commitments to the Community

Prior to the consummation of the merger, IBKC will use its reasonable best efforts to establish the Louisiana First Horizon Foundation, focused on community support in Louisiana. The initial members of the board of trustees of the Louisiana First Horizon Foundation will be selected by the IBKC board of directors and the First Horizon board of directors prior to the consummation of the merger, with the First Horizon board of directors entitled to select one (1) initial member and the IBKC board of directors entitled to select the remaining initial members. Upon consummation of the merger, the combined company will contribute $20 million in cash to the Louisiana First Horizon Foundation.

Restructuring Efforts

The merger agreement provides that if either IBKC or First Horizon fails to obtain the required vote of its holders of common stock to approve the merger agreement or if First Horizon fails to obtain the required vote of its holders of common stock to approve the First Horizon charter amendment, each of the parties will in good faith use its reasonable best efforts to negotiate a restructuring of the transactions provided for in the merger agreement (provided that neither party

151

will have any obligation to alter or change any material terms, including the amount or kind of the consideration to be issued to holders of the capital stock of IBKC as provided for in the merger agreement, in a manner adverse to such party or its shareholders, or any term that would adversely affect the tax treatment of the transactions contemplated in the merger agreement) and/or resubmit the merger agreement or the transactions contemplated thereby (or as restructured) to its respective holders of common stock for approval.

Certain Additional Covenants

The merger agreement also contains additional covenants, including, among others, covenants relating to the filing of this joint proxy statement/prospectus, obtaining required consents, the listing of the shares of First Horizon common stock and rollover First Horizon preferred stock or rollover First Horizon depositary shares to be issued in the merger, access to information of the other company, advice of changes, exemption from takeover laws, shareholder litigation relating to the transactions contemplated by the merger agreement, the coordination of dividend declarations, the assumption by First Horizon of IBKC indebtedness, public announcements with respect to the transactions contemplated by the merger agreement and the First Horizon charter amendment.

Combined Company Governance and Headquarters Matters

Under the merger agreement, First Horizon and IBKC have agreed to certain provisions relating to the governance and headquarters of the combined company, including the composition of the combined company board of directors and committees; the roles of Chairman, lead director, President and Chief Executive Officer; and identification of members of the combined company and combined bank’s management team. For a more detailed description of the governance matters relating to the combined company, see the section entitled “The Merger—Governance of the Combined Company After the Merger” beginning on page 129.

Shareholder Meetings and Recommendation of First Horizon’s and IBKC’s Boards of Directors

Each of First Horizon and IBKC has agreed to call a meeting of its shareholders for the purpose of voting upon the approval of the merger agreement and the First Horizon charter amendment (in the case of First Horizon shareholders) and to use reasonable best efforts to cause the meetings to occur as promptly as reasonably practicable and on the same date. The board of directors of each of First Horizon and IBKC has agreed to use its reasonable best efforts to obtain from its shareholders the vote required to approve the merger agreement and the First Horizon charter amendment (in the case of First Horizon shareholders), including by communicating to its shareholders the First Horizon board recommendation and the IBKC board recommendation, as applicable. Each of First Horizon and IBKC has agreed that each of First Horizon and IBKC and their respective boards of directors will not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the First Horizon board recommendation, in the case of First Horizon, or the IBKC board recommendation, in the case of IBKC, (ii) fail to make the First Horizon board recommendation, in the case of First Horizon, or the IBKC board recommendation, in the case of IBKC, (iii) adopt, approve, recommend or endorse an acquisition proposal (as defined in “—Agreement Not to Solicit Other Offers” below) or publicly announce an intention to adopt, approve, recommend or endorse an acquisition proposal, (iv) fail to publicly and without qualification (A) recommend against any acquisition proposal or (B) reaffirm the First Horizon board recommendation, in the case of First Horizon, or the IBKC board recommendation, in the case of IBKC, in each case within ten (10) business days (or such fewer number of days as remains prior to the First Horizon special meeting or the IBKC special meeting, as applicable) after an acquisition proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing a “recommendation change”).

However, subject to certain termination rights described in “—Termination of the Merger Agreement” below, if the First Horizon board of directors or the IBKC board of directors, after

152

receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the First Horizon board recommendation or the IBKC board recommendation, as applicable, then, in the case of First Horizon, prior to the receipt of the approval of the First Horizon merger proposal and the First Horizon charter amendment proposal by holders of First Horizon common stock (the “requisite First Horizon vote”), and in the case of IBKC, prior to the receipt of the approval of the IBKC merger proposal by holders of IBKC common stock (the “requisite IBKC vote”), it may submit the merger agreement to its shareholders without recommendation and may communicate the basis for its lack of a recommendation to its shareholders to the extent required by law, provided that (1) it gives the other party at least three (3) business days’ prior written notice of its intention to take such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an acquisition proposal, the latest material terms and conditions and the identity of the third party in any such acquisition proposal, or any amendment or modification thereof, or a description in reasonable detail of such other event or circumstances) and (2) at the end of such notice period, it takes into account any amendment or modification to the merger agreement proposed by the other party and, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the First Horizon board recommendation or IBKC board recommendation, as the case may be. Any material amendment to any acquisition proposal will require a new notice period.

Notwithstanding any recommendation change by the First Horizon board of directors or the IBKC board of directors, unless the merger agreement has been terminated in accordance with its terms, each party is required to convene a meeting of its shareholders and to submit the merger agreement and the First Horizon charter amendment (in the case of First Horizon shareholders) to a vote of such shareholders. First Horizon and IBKC must adjourn or postpone such meeting if there are insufficient shares of First Horizon common stock or IBKC common stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting First Horizon or IBKC, as applicable, it has not received proxies representing a sufficient number of shares necessary for approval of the merger agreement or the First Horizon charter amendment (in the case of First Horizon shareholders), and subject to the terms and conditions of the merger agreement, IBKC or First Horizon, as applicable, will continue to use reasonable best efforts to solicit proxies from its shareholders.

Agreement Not to Solicit Other Offers

Each of First Horizon and IBKC has agreed that it will not, and will cause, and use its reasonable best efforts to cause, each of its subsidiaries and its and their respective officers, directors, employees, agents, advisors and representatives not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any acquisition proposal, (ii) engage or participate in any negotiations concerning any acquisition proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any acquisition proposal (except to notify a person that has made or, to the knowledge of such party, is making inquiries with respect to, or is considering making, an acquisition proposal, of the existence of such duties) or (iv) unless the merger agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other similar agreement (whether written or oral, binding or nonbinding) (other than an acceptable confidentiality agreement entered into in accordance with the merger agreement) in connection with or relating to any acquisition proposal. For purposes of the merger agreement, an “acquisition proposal” means, with respect to First Horizon or IBKC, as applicable, other than the transactions contemplated by the merger agreement, any offer, proposal or inquiry relating to, or any third-party indication of interest in, (i) any acquisition or purchase, direct or

153

indirect, of twenty-five percent (25%) or more of the consolidated assets of a party and its subsidiaries or twenty-five percent (25%) or more of any class of equity or voting securities of a party or its subsidiaries whose assets, individually or in the aggregate, constitute more than twenty-five percent (25%) of the consolidated assets of the party, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third-party beneficially owning twenty-five percent (25%) or more of any class of equity or voting securities of a party or its subsidiaries whose assets, individually or in the aggregate, constitute more than twenty-five percent (25%) of the consolidated assets of the party or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving a party or its subsidiaries whose assets, individually or in the aggregate, constitute more than twenty-five percent (25%) of the consolidated assets of the party.

However, in the event that after the date of the merger agreement and prior to the receipt of the required vote of First Horizon shareholders to approve the merger agreement and the First Horizon charter amendment, in the case of First Horizon, or the required vote of IBKC shareholders to approve the merger agreement, in the case of IBKC, a party receives an unsolicited bona fide written acquisition proposal, it may, and may permit its subsidiaries and its and its subsidiaries’ officers, directors, agents, advisors and representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in negotiations or discussions with the person making the acquisition proposal if the First Horizon or IBKC board of directors, as applicable, concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law, provided that, prior to furnishing and confidential or nonpublic information, such party provides such information to the other party to the merger agreement and enters into a confidentiality agreement with the person making such acquisition proposal on terms no less favorable to it than the confidentiality agreement between First Horizon and IBKC, and which confidentiality agreement does not provide such person with any exclusive right to negotiate with such party.

Each of First Horizon and IBKC has also agreed to, and to cause its officers, directors, agents, advisors and representatives to, immediately cease and terminate any activities, discussions or negotiations conducted before the date of the merger agreement with any person other than First Horizon or IBKC, with respect to any acquisition proposal. In addition, each party has agreed to (1) promptly (and within twenty-four (24) hours) advise the other party following receipt of any acquisition proposal or any inquiry which could reasonably be expected to lead to an acquisition proposal, and the substance thereof (including the material terms and conditions of and the identity of the person making such inquiry or acquisition proposal), to provide the other party with an unredacted copy of any such acquisition proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or acquisition proposal, and to keep the other party reasonably apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the material terms of such inquiry or acquisition proposal and (2) use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its subsidiaries is a party.

Conditions to Complete the Merger

First Horizon’s and IBKC’s respective obligations to complete the merger are subject to the satisfaction or waiver, at or prior to the effective time, of the following conditions:

| • |  | the approval of the merger agreement and the First Horizon charter amendment by holders of First Horizon common stock, and the approval of the merger agreement by holders of IBKC common stock;
| • |  | the authorization for listing on the NYSE, subject to official notice of issuance, of the First Horizon common stock and First Horizon preferred stock (or depositary shares with respect thereof) to be issued in the merger;

154

| • |  | all requisite regulatory approvals having been obtained and remaining in full force and effect, and all statutory waiting periods in respect thereof having expired or been terminated, without the imposition of any requirement to take or commit to take any action or agree to any condition or restriction that would reasonably be expected to have a material adverse effect on the combined company and its subsidiaries, taken as a whole, after giving effect to the merger;
| • |  | the effectiveness of the registration statement of which this joint proxy statement/prospectus is a part, and the absence of any stop order (or proceedings for such purpose initiated or threatened and not withdrawn);
| • |  | no order, injunction, or decree by any court or governmental entity of competent jurisdiction or other legal restraint or prohibition preventing the completion of the merger, the bank merger or any of the other transactions contemplated by the merger agreement being in effect, and no law, statute, rule, regulation, order, injunction or decree having been enacted, entered, promulgated or enforced by any governmental entity which prohibits or makes illegal the consummation of the merger, the bank merger or any of the other transactions contemplated by the merger agreement;
| • |  | the accuracy of the representations and warranties of the other party contained in the merger agreement as of the date on which the merger agreement was entered into and as of the date on which the merger is completed, subject to the materiality standards provided in the merger agreement (and the receipt by each party of an officers’ certificate from the other party to such effect);
| • |  | the performance by the other party in all material respects of all obligations, covenants and agreements required to be performed by it under the merger agreement at or prior to the date on which the merger is completed (and the receipt by each party of an officers’ certificate from the other party to such effect); and
| • |  | receipt by such party of an opinion of legal counsel to the effect that on the basis of facts, representations and assumptions set forth or referred to in such opinion, the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code.

Neither First Horizon nor IBKC can provide assurance as to when or if all of the conditions to the merger can or will be satisfied or waived by the appropriate party.

Termination of the Merger Agreement

The merger agreement can be terminated at any time prior to completion of the merger, whether before or after the receipt of the required vote to approve the merger agreement by First Horizon shareholders or IBKC shareholders, in the following circumstances:

| • |  | by mutual written consent of First Horizon and IBKC;
| • |  | by either First Horizon or IBKC if any governmental entity that must grant a requisite regulatory approval has denied approval of the merger or the bank merger and such denial has become final and nonappealable or any governmental entity of competent jurisdiction has issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the merger or the bank merger, unless the failure to obtain a requisite regulatory approval is due to the failure of the party seeking to terminate the merger agreement to perform or observe its obligations, covenants and agreements under the merger agreement;
| • |  | by either First Horizon or IBKC if the merger has not been completed on or before the termination date, unless the failure of the merger to be completed by such date is due to the failure of the party seeking to terminate the merger agreement to perform or observe its obligations, covenants and agreements under the merger agreement;

155

| • |  | by either First Horizon or IBKC (provided that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained in the merger agreement) if there is a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty ceases to be true) set forth in the merger agreement on the part of the other party which either individually or in the aggregate would constitute, if occurring or continuing on the date the merger is completed, the failure of a closing condition of the terminating party and which is not cured within forty-five (45) days following written notice to the party committing such breach, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the termination date);
| • |  | by IBKC, if (1) First Horizon or the First Horizon board of directors has made a recommendation change or (2) First Horizon or the First Horizon board of directors breaches in any material respect its obligations relating to non-solicitation of acquisition proposals or its obligations related to shareholder approval and the First Horizon board recommendation; or
| • |  | by First Horizon, if (1) IBKC or the IBKC board of directors has made a recommendation change or (2) IBKC or the IBKC board of directors breaches in any material respect its obligations relating to non-solicitation of acquisition proposals or its obligations related to shareholder approval and the IBKC board recommendation.

Neither First Horizon nor IBKC is permitted to terminate the merger agreement as a result of any increase or decrease in the market price of First Horizon common stock or IBKC common stock.

Effect of Termination

If the merger agreement is terminated, it will become void and have no effect, except that (1) neither First Horizon nor IBKC will be relieved or released from any liabilities or damages arising out of its willful and material breach of any provision of the merger agreement and (2) designated provisions of the merger agreement will survive the termination, including those relating to payment of fees and expenses, the confidential treatment of information and the termination fee described below. For purposes of the merger agreement, “willful and material breach” means a material breach of, or material failure to perform any of the covenants or other agreements contained in, the merger agreement that is a consequence of an act or failure to act by the breaching or non-performing party with actual knowledge that such party’s act or failure to act would, or would reasonably be expected to, result in or constitute such breach of or such failure of performance under the merger agreement.

Termination Fee

IBKC will pay First Horizon a termination fee of $156 million in cash (the “termination fee”) if the merger agreement is terminated in the following circumstances:

| • |  | In the event that the merger agreement is terminated by First Horizon pursuant to the last bullet set forth under “—Termination of the Merger Agreement” above. In such case, the termination fee must be paid to First Horizon within two (2) business days of the date of termination.
| • |  | In the event, after the date of the merger agreement and prior to the termination of the merger agreement, a bona fide acquisition proposal has been communicated to or otherwise made known to the IBKC board of directors or IBKC’s senior management or has been made directly to IBKC shareholders, or any person has publicly announced (and not publicly withdrawn at least two (2) business days prior to the IBKC special meeting) an acquisition proposal with respect to IBKC, and (i) (A) thereafter the merger agreement is terminated by either First Horizon or IBKC because the merger has not been completed prior to the termination date, and IBKC has not obtained the required vote of IBKC shareholders approving the merger agreement but all other conditions to IBKC’s obligation to complete

156

|  |  | the merger had been satisfied or were capable of being satisfied prior to such termination or (B) thereafter the merger agreement is terminated by First Horizon based on a breach of the merger agreement by IBKC that would constitute the failure of an applicable closing condition, and (ii) prior to the date that is twelve (12) months after the date of such termination, IBKC enters into a definitive agreement or consummates a transaction with respect to an acquisition proposal (whether or not the same acquisition proposal as that referred to above), provided that for purposes of the foregoing, all references in the definition of acquisition proposal to “twenty-five percent (25%)” will instead refer to “fifty percent (50%).” In such case, the termination fee must be paid to First Horizon on the earlier of the date IBKC enters into such definitive agreement and the date of consummation of such transaction.

First Horizon will pay IBKC the termination fee if the merger agreement is terminated in the following circumstances:

| • |  | In the event that the merger agreement is terminated by IBKC pursuant to the second to last bullet set forth under “—Termination of the Merger Agreement” above. In such case the termination fee must be paid to IBKC within two (2) business days of the date of termination.
| • |  | In the event, after the date of the merger agreement and prior to the termination of the merger agreement, a bona fide acquisition proposal has been communicated to or otherwise made known to the First Horizon board of directors or First Horizon’s senior management or has been made directly to First Horizon shareholders, or any person has publicly announced (and not publicly withdrawn at least two (2) business days prior to the First Horizon special meeting) an acquisition proposal with respect to First Horizon, and (i) (A) thereafter the merger agreement is terminated by either First Horizon or IBKC because the merger has not been completed prior to the termination date, and First Horizon has not obtained the required vote of First Horizon shareholders approving the merger agreement but all other conditions to First Horizon’s obligation to complete the merger had been satisfied or were capable of being satisfied prior to such termination or (B) thereafter the merger agreement is terminated by IBKC based on a breach of the merger agreement by First Horizon that would constitute the failure of an applicable closing condition and (ii) prior to the date that is twelve (12) months after the date of such termination, First Horizon enters into a definitive agreement or consummates a transaction with respect to an acquisition proposal (whether or not the same acquisition proposal as that referred to above), provided that for purposes of the foregoing, all references in the definition of acquisition proposal to “twenty-five percent (25%)” will instead refer to “fifty percent (50%).” In such case, the termination fee must be paid to IBKC on the earlier of the date First Horizon enters into such definitive agreement and the date of consummation of such transaction.

Expenses and Fees

Except as otherwise expressly provided in the merger agreement, all costs and expenses incurred in connection with the merger agreement and the transactions contemplated thereby will be paid by the party incurring such expense, except that the costs and expenses of printing and mailing this joint proxy statement/prospectus and all filing and other fees paid to the SEC in connection with the merger and the other transactions contemplated by the merger agreement will be borne equally by First Horizon and IBKC.

Amendment, Waiver and Extension of the Merger Agreement

Subject to compliance with applicable law, the merger agreement may be amended by the parties at any time before or after the receipt of the requisite First Horizon vote or the requisite IBKC vote, except that after the receipt of the requisite First Horizon vote or the requisite IBKC vote, there may not be, without further approval of the holders of common stock of First Horizon or IBKC, as

157

applicable, any amendment of the merger agreement that requires such further approval under applicable law.

At any time prior to the completion of the merger, each of the parties may, to the extent legally allowed, extend the time for the performance of any of the obligations or other acts of the other party, waive any inaccuracies in the representations and warranties of the other party contained in the merger agreement or in any document delivered by such other party pursuant to the merger agreement, and waive compliance with any of the agreements or satisfaction of any conditions for its benefit contained in the merger agreement, except that after the receipt of the requisite First Horizon vote or the requisite IBKC vote, there may not be, without further approval of the holders of common stock of First Horizon or IBKC, as applicable, any extension or waiver of the merger agreement or any portion thereof that requires further approval under applicable law.

Governing Law

The merger agreement is governed by and will be construed in accordance with the laws of the State of Delaware applicable to agreements made and to be performed within the State of Delaware, without regard to any applicable conflicts of law principles (except that matters relating to the fiduciary duties of the IBKC board of directors will be subject to the laws of the State of Louisiana and matters relating to the fiduciary duties of the First Horizon board of directors will be subject to the laws of the State of Tennessee).

Specific Performance

First Horizon and IBKC will be entitled to an injunction or injunctions to prevent breaches or threatened breaches of the merger agreement (including the parties’ obligations to consummate the merger), in addition to any other remedy to which they are entitled at law or in equity.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

The following discussion sets forth the anticipated material United States federal income tax consequences of the merger to U.S. holders (as defined below) of IBKC common stock or IBKC preferred stock, as applicable, that exchange their shares of IBKC common stock or IBKC preferred stock, as applicable, for the merger consideration. This discussion does not address any tax consequences arising under the laws of any state, local or foreign jurisdiction, or under any United States federal laws other than those pertaining to income tax. This discussion is based upon the Internal Revenue Code of 1986, as amended, the regulations promulgated under the Code and court and administrative rulings and decisions, all as in effect on the date of this joint proxy statement/prospectus. These laws may change, possibly retroactively, and any change could affect the accuracy of the statements and conclusions set forth in this discussion. To the extent this section consists of statements as to matters of U.S. federal income tax law, this section constitutes the opinion of Sullivan & Cromwell and the opinion of Simpson Thacher.

This discussion addresses only those holders of IBKC common stock and IBKC preferred stock that hold their shares of IBKC common stock or IBKC preferred stock, as applicable, as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment). Further, this discussion does not address all aspects of United States federal income taxation that may be relevant to you in light of your particular circumstances or that may be applicable to you if you are subject to special treatment under the United States federal income tax laws, including if you are:

| • |  | a financial institution;
| • |  | a tax-exempt organization;
| • |  | a pass-through entity (or an investor in a pass-through entity);
| • |  | an insurance company;
| • |  | a mutual fund;
| • |  | a dealer or broker in stocks and securities, or currencies;
| • |  | a trader in securities that elects mark-to-market treatment;
| • |  | a holder of IBKC common stock or IBKC preferred stock that received IBKC common stock or IBKC preferred stock, as applicable, through the exercise of an employee stock option, through a tax qualified retirement plan or otherwise as compensation;
| • |  | a person that is not a U.S. holder;
| • |  | a person that has a functional currency other than the U.S. dollar;
| • |  | a real estate investment trust;
| • |  | regulated investment companies;
| • |  | A dissenting holder of IBKC preferred stock that owns or is deemed to own First Horizon stock; or
| • |  | a holder of IBKC common stock or IBKC preferred stock that holds IBKC common stock or IBKC preferred stock as part of a hedge, straddle, constructive sale, wash sale, conversion or other integrated transaction.

In addition, the discussion does not address any alternative minimum tax or any state, local or foreign tax consequences of the merger, nor does it address any tax consequences arising under the unearned income Medicare contribution tax pursuant to the Health Care and Education Reconciliation Act of 2010. Determining the actual tax consequences of the merger to you may be complex. They will depend on your specific situation and on factors that are not within the control of IBKC or First Horizon. You should consult with your own tax advisor as to the tax consequences of the merger in your particular circumstances.

159

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of IBKC common stock or IBKC preferred stock that is for United States federal income tax purposes (i) an individual citizen or resident of the United States, (ii) a corporation, or entity treated as a corporation, organized in or under the laws of the United States or any state thereof or the District of Columbia, (iii) a trust if (a) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more United States persons have the authority to control all substantial decisions of the trust or (b) such trust has made a valid election to be treated as a U.S. person for United States federal income tax purposes or (iv) an estate, the income of which is includible in gross income for United States federal income tax purposes regardless of its source.

The United States federal income tax consequences to a partner in an entity or arrangement that is treated as a partnership for United States federal income tax purposes and that holds IBKC common stock or IBKC preferred stock generally will depend on the status of the partner and the activities of the partnership. Partners in a partnership holding IBKC common stock or IBKC preferred stock should consult their own tax advisors.

Tax Consequences of the Merger Generally

The parties intend for the merger to qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is a condition to First Horizon’s obligation to complete the merger that First Horizon receive an opinion from Sullivan & Cromwell (or other nationally recognized tax counsel), dated the closing date, to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. It is a condition to IBKC’s obligation to complete the merger that IBKC receive an opinion from Simpson Thacher (or other nationally recognized tax counsel), dated the closing date, to the effect that the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Code. These opinions will be based on representation letters (the “Representation Letters”) provided by First Horizon and IBKC and on customary factual assumptions. Neither of the opinions described above will be binding on the Internal Revenue Service. First Horizon and IBKC have not sought and will not seek any ruling from the Internal Revenue Service regarding any matters relating to the merger, and as a result, there can be no assurance that the Internal Revenue Service will not assert, or that a court would not sustain, a position contrary to any of the conclusions set forth below. In addition, if any of the representations, warranties, covenants or assumption upon which the opinions described above are based (the “Representations and Assumptions”) are inconsistent with the actual facts, or if any condition contained in the merger agreement and affecting these opinions is breached or is waived by any party, the U.S. federal income tax consequences of the merger could be adversely affected.

Based on the facts and representations set forth or referred to in the opinions included as exhibits to this joint proxy statement/prospectus filed with the SEC, and subject to the Representations and Assumptions (and the receipt of the Representation Letters) and the qualifications, assumptions and limitations stated in this joint proxy statement/prospectus, it is the opinion of Simpson Thacher and Sullivan & Cromwell that the merger will constitute a “reorganization” within the meaning of Section 368(a) of the Code. The foregoing opinions are filed as Exhibit 8.1 and 8.2 to this registration statement of which this joint proxy statement/prospectus forms a part.

As a “reorganization,” the material U.S. federal income tax consequences of the merger to U.S. holders of IBKC common stock or IBKC preferred stock, as applicable, are set forth in the remainder of this discussion:

| • |  | a holder who receives solely shares of First Horizon common stock (or receives First Horizon common stock and cash solely in lieu of a fractional share) or rollover First Horizon preferred stock, as applicable, in exchange for shares of IBKC common stock or IBKC preferred stock, as applicable, generally will not recognize any gain or loss upon the merger, except with respect to the cash received in lieu of fractional share of First Horizon common stock;

160

| • |  | the aggregate tax basis of the First Horizon common stock or rollover First Horizon preferred stock, as applicable, received in the merger (including fractional share interests in First Horizon common stock deemed received and exchanged for cash) will be equal to the holder’s aggregate tax basis in the IBKC common stock or IBKC preferred stock, as applicable, for which it is exchanged, decreased by the amount of cash received in the merger, and increased by the amount of gain recognized on the exchange (regardless of whether such gain is classified as capital gain, or as dividend income, as discussed below), but excluding any gain recognized with respect to fractional share interests in First Horizon common stock for which cash is received, as discussed below;
| • |  | the holding period of First Horizon common stock or rollover First Horizon preferred stock, as applicable, received in the merger (including any fractional shares deemed received and redeemed as described below) will include the holder’s holding period of the IBKC common stock or IBKC preferred stock, as applicable, for which it is exchanged.

If holders acquired different blocks of IBKC common stock or IBKC preferred stock at different times and at different prices, a holder’s tax basis and holding period in First Horizon common stock or First Horizon preferred stock may be determined with reference to each block of IBKC common stock or IBKC preferred stock.

Cash Instead of a Fractional Share

A holder of IBKC common stock who receives cash instead of a fractional share of First Horizon common stock will be treated as having received the fractional share of First Horizon common stock pursuant to the merger and then as having sold that fractional share for cash. As a result, generally such a holder will recognize gain or loss equal to the difference between the amount of cash received and the basis allocable to such holder’s fractional share of First Horizon common stock. This gain or loss generally will be capital gain or loss, and will be long-term capital gain or loss if, as of the effective time of the merger, the holding period for the shares (including the holding period of IBKC common stock surrendered therefor) is greater than one year. The deductibility of capital losses is subject to limitations.

Dissenting IBKC Preferred Stockholders

With respect to dissenting holders of IBKC preferred stock, a holder who receives solely cash for shares of IBKC preferred stock will recognize gain or loss equal to the difference between the amount of cash received by a holder of IBKC preferred stock and such holder’s tax basis in such holder’s shares of IBKC preferred stock.

If holders acquired different blocks of IBKC preferred stock at different times or different prices, any gain or loss may be determined with reference to each block of IBKC preferred stock. Any such holders should consult their tax advisors regarding the manner in which cash or rollover First Horizon preferred stock, as applicable, received in the merger should be allocated among different blocks of IBKC preferred stock and with respect to identifying the bases or holding periods of the particular shares of rollover First Horizon preferred stock received in the merger.

Gain or loss that holders of IBKC preferred stock recognize in connection with the merger will generally constitute capital gain or loss and will constitute long-term capital gain or loss if such holders have held their IBKC preferred stock for more than one year as of the effective time of the merger. Long-term capital gain of certain non-corporate IBKC preferred stock including individuals, is generally taxed at preferential rates. The deductibility of capital losses is subject to limitations.

Dissenting IBKC Preferred and IBKC Common Stockholders

With respect to dissenting holders of IBKC preferred stock, a holder who receives both cash for shares of IBKC preferred stock and shares of First Horizon common stock in respect of IBKC common stock, such cash may be allocated entirely to the IBKC preferred stock and such dissenting

161

holder will recognize gain (but not loss) equal to the difference between the amount of such cash received by a holder of IBKC preferred stock and such holder’s tax basis in such holder’s shares of IBKC preferred stock.

The amount of any such gain would be taxed as described above under “—Dissenting IBKC Preferred Stockholders.”

Backup Withholding

Payments of cash to a non-corporate holder of IBKC common stock or IBKC preferred stock, as applicable, in connection with the merger may be subject to information reporting and backup withholding (currently at a rate of 24%). Such holders of IBKC common stock or IBKC preferred stock, as applicable, generally will not be subject to backup withholding, however, if the holder:

| • |  | furnishes a correct taxpayer identification number and any other required information to the exchange agent; or
| • |  | provides proof of an applicable exemption from backup withholding.

Any amounts withheld under the backup withholding rules are not additional tax and will generally be allowed as a refund or credit against the holder’s United States federal income tax liability, provided the required information is timely furnished to the Internal Revenue Service.

This summary of certain material United States federal income tax consequences is for general information only and is not tax advice. You are urged to consult your tax advisor with respect to the application of United States federal income tax laws to your particular situation as well as any tax consequences arising under the United States federal estate or gift tax rules, or under the laws of any state, local, foreign or other taxing jurisdiction.

UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The following tables show unaudited pro forma condensed combined consolidated financial information about the financial condition and results of operations, including per share data, after giving effect to the SunTrust Purchase and the merger with IBKC and other pro forma adjustments. The unaudited pro forma financial information assumes that the transactions are accounted for under the acquisition method of accounting, and the assets and liabilities of the purchased branches of SunTrust Bank and IBKC will generally be recorded by First Horizon at their respective fair values as of the date the transactions were or are (as applicable) completed. The unaudited pro forma condensed balance sheet gives effect to the transactions as if the transactions had occurred on December 31, 2019. The unaudited pro forma combined income statement for the year ended December 31, 2019 gives effect to the transactions as if the transactions had become effective at January 1, 2019. The unaudited selected pro forma combined financial information has been derived from and should be read in conjunction with the consolidated financial statements and related notes of First Horizon, which are incorporated in this joint proxy statement/prospectus by reference, the consolidated financial statements and related notes of IBKC, which are incorporated in this joint proxy statement/prospectus by reference, and the more detailed unaudited pro forma condensed combined financial information, including the notes thereto, appearing elsewhere in this joint proxy statement/prospectus. See “Where You Can Find More Information” beginning on page 218.

The unaudited pro forma condensed combined financial information is presented for illustrative purposes only and does not indicate the financial results of the combined company had the companies actually been combined at the beginning of each period presented, nor the impact of possible business model changes. The unaudited pro forma condensed combined financial information also does not consider any potential effects of changes in market conditions on revenues, expense efficiencies, asset dispositions, and share repurchases, among other factors, including those discussed in the section entitled “Risk Factors” beginning on page 41. In addition, as explained in more detail in the below accompanying notes, the preliminary allocation of the pro forma purchase prices for both transactions reflected in the unaudited pro forma condensed combined financial information is subject to adjustment and may vary materially from the actual purchase price allocation that will be recorded upon completion of the transactions.

Note 1—Basis of Presentation

The unaudited pro forma combined consolidated financial information and explanatory notes have been prepared to illustrate the effects of the SunTrust Purchase and the merger under the acquisition method of accounting with First Horizon treated as the acquirer. The unaudited pro forma combined consolidated financial information is presented for illustrative purposes only and does not necessarily indicate the financial results of the combined companies had the companies actually been combined at the beginning of each period presented, nor does it necessarily indicate the results of operations in future periods or the future financial position of the combined entities. Under the acquisition method of accounting, the assets and liabilities from the SunTrust Purchase and the merger as of their respective effective date (as set forth in the applicable agreement) will generally be recorded by First Horizon at their respective fair values with the excess of purchase price over the acquired net assets allocated to goodwill.

The SunTrust Purchase, which is currently expected to be completed in the second quarter of 2020, results in the acquisition of branch loans and related fixed assets and the assumption of branch deposits of SunTrust Bank by First Horizon for approximately $586 million in cash.

The merger, which is currently expected to be completed in mid 2020, provides for IBKC common shareholders to receive 4.584 shares of First Horizon common stock for each share of IBKC common stock they hold immediately prior to the merger closing. Based on the closing trading price of First Horizon common stock on the NYSE on February 28, 2020, the value of the merger consideration per share of IBKC common stock was $61.10. Based on the closing trading price of First Horizon common stock on the NYSE on [ ], 2020, the last practicable date before the date of this joint proxy statement/prospectus, the value of the merger consideration per share of IBKC common stock was [ ].

The pro forma allocation of purchase price reflected in the unaudited pro forma financial information is subject to adjustment and may vary from the actual purchase price allocation that will be recorded at the closing date. Adjustments may include, but not be limited to, changes in (i) IBKC’s balance sheet through the effective date of the merger; (ii) the aggregate value of merger consideration paid if the price of First Horizon’s shares vary from the assumed $13.33 per share, which represents the closing share price of First Horizon common stock on February 28, 2020; (iii) total merger related expenses if consummation and/or implementation costs vary from currently estimated amounts; and (iv) the underlying values of assets and liabilities if market conditions differ from current assumptions.

The accounting policies of both First Horizon and IBKC are in the process of being reviewed in detail. Upon completion of such review, conforming adjustments or financial statement reclassification may be determined.

In June 2016, the Financial Accounting Standards Board issued Accounting Standards Update (“ASU”) 2016-13, “Measurement of Credit Losses on Financial Instruments,” which revises the measurement and recognition of credit losses for assets measured at amortized cost (e.g., held-to-maturity (“HTM”) loans and debt securities) and available-for-sale (“AFS”) debt securities. The provisions of ASU 2016-13 and multiple related accounting standards that were subsequently issued (collectively the “Credit Impairment Standards”) are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years and will be generally adopted through cumulative-effect adjustments to retained earnings and affected asset classifications as of the beginning of the first reporting period in the year of adoption. Accordingly, the unaudited pro forma condensed combined financial information does not reflect any adjustments for the effects of adopting the Credit Impairment Standards. For the most recent information related to the pending adoption of the Credit Impairment Standards, reference should be made to the notes to the historical consolidated financial statements included in First Horizon’s Annual Report on Form 10-K for the year ended December 31, 2019 and the notes to the historical consolidated financial statements included in IBKC’s Annual Report on Form 10-K for the period ended December 31, 2019, each of which is incorporated by reference herein.

Note 2—Preliminary Purchase Price Allocation for the SunTrust Purchase

The pro forma adjustments for the SunTrust Purchase include the estimated acquisition accounting entries to record the purchase of branch loans and related fixed assets and the assumption of branch deposits, as well as conformity adjustments to align with First Horizon’s presentation. The excess of the purchase price over the fair value of net assets acquired, net of deferred taxes, is allocated to goodwill. Estimated fair value adjustments included in the pro forma combined consolidated financial statements are based upon available information and certain assumptions considered reasonable, and are subject to change as additional information becomes available.

Other intangible assets of $33.5 million are included in the SunTrust Purchase pro forma adjustments separate from goodwill and are amortized using the sum-of-the-years-digits method or an accelerated methodology that mirrors the discounted cash flows used in the determination of fair value. Goodwill totaling $52.3 million is included in the SunTrust Purchase pro forma adjustments and is not subject to amortization.

The following schedule details significant assets purchased and liabilities assumed from the SunTrust Purchase estimated as of December 31, 2019:

(Dollars in thousands) |  |
Purchase Price |  |
Cash consideration |  |  | $ |  | 586,465 |
SunTrust Purchase Net Assets at Fair Value |  |
Assets acquired: |  |
Cash and due from banks |  |  | $ |  | 2,303,059 |
Loans |  |  |  | 489,446 |
Other intangible assets |  |  |  | 33,491 |
Premises and equipment |  |  |  | 11,262 |
Other assets |  |  |  | 23,039 |
Total assets acquired |  |  | $ |  | 2,860,297 |
Liabilities assumed: |  |
Deposits |  |  |  | 2,303,059 |
Other liabilities |  |  |  | 23,039 |
Total liabilities assumed |  |  | $ |  | 2,326,098 |
Net assets acquired |  |  | $ |  | 534,199 |
Preliminary pro forma goodwill |  |  | $ |  | 52,266 |

Note 3—Preliminary Purchase Price Allocation for IBKC

The pro forma adjustments for IBKC include the estimated acquisition accounting entries to record the merger. The excess of the purchase price over the acquisition accounting value of net assets acquired, net of deferred taxes, is allocated to goodwill. Estimated fair value adjustments included in the pro forma combined consolidated financial statements are based upon available information and certain assumptions considered reasonable, and may be subject to change as additional information becomes available.

Core deposits and other intangible assets of $356.2 million resulting from the merger have been recorded separately from goodwill and have been amortized over an estimated ten year average life using the sum-of-the-years-digits method or an accelerated methodology that mirrors the timing of related expected cash flows used in the determination of fair value. Goodwill totaling $381.1 million resulting from the merger is not subject to amortization. The purchase price is based on First Horizon’s price per common share at the closing date, which has not yet occurred. Accordingly, a 10 percent increase or decrease in First Horizon’s closing sale price per share of common stock on February 28, 2020 (which was $13.33) would result in a corresponding goodwill adjustment of approximately $322.9 million.

Note 5—Estimated Cost Savings and Merger Integration Costs

First Horizon expects to realize approximately $170 million, or 25 percent of IBKC’s current noninterest expense, in annual pre-tax cost savings following the merger. The estimated cost savings is expected to be 75 percent realized in the run-rate by the end of fiscal year 2021 and fully realized during fiscal year 2022 and is excluded from this pro forma analysis.

Anticipated future merger and integration-related costs are not included in the pro forma combined statements of income since they will be recorded in the combined results of income as they are incurred prior to, or after completion of, the merger and are not indicative of what the historical results of the condensed combined company would have been had the companies been actually

170

combined during the periods presented. Anticipated future merger and integration-related pre-tax costs are estimated to be $440 million.

Note 6—Divestiture of IBKC and/or First Horizon Bank Branches

After regulatory assessment of competitive considerations of the merger in accordance with regulatory guidelines, IBKC may be required to divest branches in certain banking areas in order to obtain regulatory approvals to complete the transactions contemplated by the merger agreement. If required by regulatory authorities, branches will be divested in certain areas in a manner sufficient to eliminate such regulatory authorities’ competitive concerns. Presently, however, no potential branch divestitures have been identified by regulators, none are expected by the parties, and therefore none are included in the pro forma analysis. See “The Merger—Regulatory Approvals” beginning on page 132.

171

DESCRIPTION OF ROLLOVER FIRST HORIZON PREFERRED STOCK

At the effective time, each share of IBKC series B preferred stock, IBKC series C preferred stock and IBKC series D preferred stock, in each case issued and outstanding immediately prior to the effective time and excluding dissenting shares, will be converted into the right to receive one (1) share of newly created First Horizon series B preferred stock, First Horizon series C preferred stock and First Horizon series D preferred stock, respectively. The rollover First Horizon preferred stock will have terms that are the same as the terms of the applicable series of outstanding IBKC preferred stock, taking into account that IBKC will not be the surviving entity in the merger and, with respect to the IBKC series B preferred stock, taking into account that the optional redemption date for the First Horizon series B preferred stock may be deferred until the first dividend payment date that is at least five (5) years from the closing date. The following briefly summarizes the terms and provisions of the rollover First Horizon preferred stock. The form of Articles of Amendment for the rollover First Horizon preferred stock is attached to the joint proxy statement/prospectus as Annex G.

First Horizon Preferred Stock

The First Horizon charter authorizes First Horizon to issue up to 5,000,000 shares of serial preferred stock, no par value. The First Horizon board of directors is authorized to cause the issuance of preferred stock, in one or more series, from time to time with such voting powers, full or limited, or without voting powers, and with such designations, preferences and relative participating, optional or other special rights and qualifications, limitations and restrictions thereof, as may be provided in a resolution or resolutions adopted by the First Horizon board of directors. As of the date of this joint proxy statement/prospectus, there are 1,000 shares of First Horizon Non-Cumulative Perpetual Preferred Stock, Series A, issued and outstanding.

First Horizon Series B Preferred Stock

General

The “6.625% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series B,” which we refer to in this section as the “Series B preferred stock,” will be designated as a new series of First Horizon’s authorized preferred stock. The Series B preferred stock, upon issuance against full payment of the purchase price for the depositary shares, will be fully paid and nonassessable. First Horizon may from time to time, without notice to or the consent of holders of the Series B preferred stock, issue additional shares of Series B preferred stock, provided that if the additional shares are not fungible for U.S. federal income tax purposes with the initial shares of such series, the additional shares shall be issued under a separate CUSIP number. The additional shares would form a single series together with all previously issued shares of Series B preferred stock. In the event First Horizon issues additional shares of Series B preferred stock, First Horizon will cause a corresponding number of additional depositary shares to be issued.

The depository will initially be the sole holder of the Series B preferred stock. The holders of depositary shares will be required to exercise their proportional rights in the shares of Series B preferred stock through the depository, as described in “First Horizon Depositary Shares” section below.

Ranking

With respect to the payment of dividends and distributions upon First Horizon’s liquidation, dissolution or winding up, the Series B preferred stock will rank (i) senior to First Horizon’s common stock and any other class or series of preferred stock that by its terms ranks junior to the Series B preferred stock, (ii) equally with the First Horizon series A preferred stock, the First Horizon series C preferred stock, the First Horizon series D preferred stock and any future series of preferred stock that First Horizon may issue that does not by its terms provide for a junior ranking and (iii) junior to all existing and future indebtedness and other liabilities and any class or series of

172

preferred stock that expressly provides in the articles of amendment creating such preferred stock that such series ranks senior to the Series B preferred stock (subject to any requisite consents prior to issuance).

The Series B preferred stock will not be convertible into, or exchangeable for, shares of any other class or series of capital stock or other securities of First Horizon and will not be subject to any sinking fund or other obligation to redeem or repurchase the Series B preferred stock. The preferred stock is not secured, is not guaranteed by First Horizon or any of its affiliates and is not subject to any other arrangement that legally or economically enhances the ranking of the Series B preferred stock.

Dividends

Holders of the Series B preferred stock will be entitled to receive, only when, as, and if declared by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), out of assets legally available under applicable law for payment, non-cumulative cash dividends based on the liquidation preference of $10,000 per share of Series B preferred stock, and no more, at a rate equal to (1) 6.625% per annum (equivalent to $1.65625 per depositary share per annum), for each semi-annual Dividend Period occurring from, and including, the original issue date of the Series B preferred stock to, but excluding, August 1, 2025 (the “Fixed Rate Period”), and (2) thereafter, three-month LIBOR plus a spread of 426.2 basis points per annum, for each quarterly Dividend Period beginning August 1, 2025 (the “Floating Rate Period”). A “Dividend Period” means the period from, and including, each Dividend Payment Date (as defined below) to, but excluding, the next succeeding Dividend Payment Date, except that the initial Dividend Period will be the period from, and including, the last dividend payment date prior to the closing.

When, as, and if declared by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), during the Fixed Rate Period, First Horizon will pay cash dividends on the Series B preferred stock semi-annually, in arrears, on February 1 and August 1 of each year (each such date, a “Fixed Period Dividend Payment Date”), beginning on February 1, 2016, and, when, as and if declared by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), during the Floating Rate Period, First Horizon will pay cash dividends on the Series B preferred stock quarterly, in arrears, on February 1, May 1, August 1 and November 1 of each year, beginning on November 1, 2025 (each such date, a “Floating Period Dividend Payment Date,” and together with the Fixed Period Dividend Payment Dates, the “Dividend Payment Dates”). First Horizon will pay cash dividends to the holders of record of shares of the Series B preferred stock as they appear on the First Horizon stock register on the applicable record date, which shall be the fifteenth calendar day before that Dividend Payment Date or such other record date fixed by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) that is not more than 60 nor less than 10 days prior to such Dividend Payment Date.

If any Dividend Payment Date on or prior to August 1, 2025 is a day that is not a business day (as defined below), then the dividend with respect to that Dividend Payment Date will instead be paid on the immediately succeeding business day, without interest or other payment in respect of such delayed payment. If any Dividend Payment Date after August 1, 2025 is a day that is not a business day, then the Dividend Payment Date will be the immediately succeeding business day unless such day falls in the next calendar month, in which case the Dividend Payment Date will instead be the immediately preceding day that is a business day, and dividends will accumulate to the Dividend Payment Date as so adjusted. A “business day” for the Fixed Rate Period means any weekday in New York, New York that is not a day on which banking institutions in those cities are authorized or required by law, regulation, or executive order to be closed. A “business day” for the Floating Rate Period means any weekday in New York, New York that is not a day on which banking institutions in those cities are authorized or required by law, regulation, or executive order to be closed, and additionally, is a London banking day (as defined below).

173

First Horizon will calculate dividends on the Series B preferred stock for the Fixed Rate Period on the basis of a 360-day year of twelve 30-day months. First Horizon will calculate dividends on the Series B preferred stock for the Floating Rate Period on the basis of the actual number of days in a Dividend Period and a 360-day year. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward. Dividends on the Series B preferred stock will cease to accumulate after the redemption date, as described below under “—Redemption,” unless First Horizon defaults in the payment of the redemption price of the shares of the Series B preferred stock called for redemption.

Dividends on the Series B preferred stock will not be cumulative or mandatory. If the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) does not declare a dividend on the Series B preferred stock for any Dividend Period prior to the related Dividend Payment Date, that dividend will not accumulate, and First Horizon will have no obligation to pay a dividend for that Dividend Period at any time, whether or not dividends on the Series B preferred stock or any other series of First Horizon preferred stock or common stock are declared for any future Dividend Period.

Dividends on the Series B preferred stock will accumulate from the original issue date at the then-applicable dividend rate on the liquidation preference amount of $10,000 per share (equivalent to $25 per depositary share). If First Horizon issues additional shares of the Series B preferred stock, dividends on those additional shares will accumulate from the original issue date of those additional shares at the then-applicable dividend rate.

The dividend rate for each Dividend Period in the Floating Rate Period will be determined by the calculation agent using three-month LIBOR as in effect on the second London banking day prior to the beginning of the Dividend Period, which date is the “dividend determination date” for the relevant Dividend Period. The calculation agent then will add three-month LIBOR as determined on the dividend determination date and the applicable spread. Once the dividend rate for the Series B preferred stock is determined, the calculation agent will deliver that information to First Horizon and the transfer agent. Absent manifest error, the calculation agent’s determination of the dividend rate for a Dividend Period for the Series B preferred stock will be final. A “London banking day” is any day on which commercial banks are open for dealings in deposits in U.S. dollars in the London interbank market.

The term “three-month LIBOR” means the London interbank offered rate for deposits in U.S. dollars for a three month period, as that rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) at approximately 11:00 a.m., London time, on the relevant dividend determination date.

If no offered rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) on the relevant dividend determination date at approximately 11:00 a.m., London time, then the calculation agent, in consultation with First Horizon, will select four major banks in the London interbank market and will request each of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time. If at least two quotations are provided, three-month LIBOR will be the arithmetic average (rounded upward if necessary to the nearest .00001 of 1%) of the quotations provided. Otherwise, the calculation agent in consultation with First Horizon will select three major banks in New York City and will request each of them to provide a quotation of the rate offered by it at approximately 11:00 a.m., New York City time, on the dividend determination date for loans in U.S. dollars to leading European banks for a three month period for the applicable Dividend Period in an amount of at least $1,000,000. If three quotations are provided, three-month LIBOR will be the arithmetic average of the quotations provided. Otherwise, three-month LIBOR for the next

Dividend Period will be equal to three-month LIBOR in effect for the then-current Dividend Period or, in the case of the first Dividend Period in the Floating Rate Period, the most recent rate on which three-month LIBOR could have been determined in accordance with the first sentence of this paragraph had the dividend rate been a floating rate during the Fixed Rate Period.

174

Priority Regarding Dividends

So long as any share of Series B preferred stock remains outstanding, (1) no dividend will be declared and paid or set aside for payment and no distribution will be declared and made or set aside for payment on any Junior Stock (as defined below) (other than a dividend payable solely in shares of Junior Stock or any dividend in connection with the implementation of a shareholder rights plan or the redemption or repurchase of any rights under such a plan), (2) no shares of Junior Stock will be repurchased, redeemed, or otherwise acquired for consideration by First Horizon, directly or indirectly (other than as a result of a reclassification of Junior Stock for or into other Junior Stock, or the exchange for or conversion into Junior Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Junior Stock or pursuant to a contractually binding requirement to buy Junior Stock pursuant to a binding stock repurchase plan existing prior to the most recently completed Dividend Period), nor will any monies be paid to or made available for a sinking fund for the redemption of any such securities by First Horizon and (3) no shares of Parity Stock (as defined below) will be repurchased, redeemed or otherwise acquired for consideration by First Horizon (other than pursuant to pro rata offers to purchase all, or a pro rata portion, of the Series B preferred stock and such Parity Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Parity Stock or Junior Stock, as a result of a reclassification of Parity Stock for or into other Parity Stock, or by conversion into or exchange for other Parity Stock or Junior Stock), during a Dividend Period, unless, in each case, the full dividends for the most recently completed Dividend Period on all outstanding shares of the Series B preferred stock have been declared and paid in full or declared and a sum sufficient for the payment of those dividends has been set aside. The foregoing limitations do not apply to purchases or acquisitions of First Horizon Junior Stock pursuant to any employee or director incentive or benefit plan or arrangement (including any of First Horizon’s employment, severance, or consulting agreements) of First Horizon’s or of any of First Horizon’s subsidiaries.

Except as provided below, for so long as any share of Series B preferred stock remains outstanding, First Horizon will not declare, pay, or set aside for payment full dividends on any Parity Stock unless First Horizon has paid in full, or set aside payment in full, in respect of all accumulated dividends for all Dividend Periods for outstanding shares of preferred stock. To the extent that First Horizon declares dividends on the Series B preferred stock and on any Parity Stock but cannot make full payment of such declared dividends, First Horizon will allocate the dividend payments on a pro rata basis among the holders of the shares of Series B preferred stock and the holders of any Parity Stock then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, First Horizon will allocate dividend payments based on the ratio between the then current and unpaid dividend payments due on the shares of Series B preferred stock and (1) in the case of cumulative Parity Stock the aggregate of the accumulated and unpaid dividends due on any such Parity Stock and (2) in the case of non-cumulative Parity Stock, the aggregate of the declared but unpaid dividends due on any such Parity Stock. No interest will be payable in respect of any dividend payment on Series B preferred stock that may be in arrears.

As used in this section, “Junior Stock” means First Horizon common stock and any other class or series of First Horizon capital stock over which the Series B preferred stock has preference or priority in the payment of dividends or in the distribution of assets on First Horizon’s liquidation, dissolution or winding up, and “Parity Stock” means the First Horizon series A preferred stock, the First Horizon series C preferred stock, the First Horizon series D preferred stock and any other class or series of First Horizon capital stock that ranks on a par with the Series B preferred stock in the payment of dividends and in the distribution of assets on First Horizon’s liquidation, dissolution or winding up, which includes any class or series of First Horizon stock hereafter authorized that ranks on a par with the Series B preferred stock in the payment of dividends and in the distribution of assets on First Horizon’s liquidation, dissolution or winding up.

Subject to the conditions described above, and not otherwise, dividends (payable in cash, stock, or otherwise), as may be determined by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), may be declared and paid on First Horizon common stock and any Junior Stock from time to time out of any funds legally available for such

175

payment, and the holders of the Series B preferred stock will not be entitled to participate in those dividends.

Liquidation Rights

Upon First Horizon’s voluntary or involuntary liquidation, dissolution or winding up, the holders of the outstanding shares of Series B preferred stock are entitled to be paid out of First Horizon assets legally available for distribution to First Horizon shareholders, before any distribution of assets is made to holders of common stock or any other Junior Stock, a liquidating distribution in the amount of a liquidation preference of $10,000 per share (equivalent to $25 per depositary share), plus the sum of any declared and unpaid dividends for prior Dividend Periods prior to the Dividend Period in which the liquidation distribution is made and any declared and unpaid dividends for the then current Dividend Period in which the liquidation distribution is made to the date of such liquidation distribution. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series B preferred stock will have no right or claim to any of First Horizon’s remaining assets.

Distributions will be made only to the extent that First Horizon assets are available after satisfaction of all liabilities to depositors, and creditors and subject to the rights of holders of any securities ranking senior to the Series B preferred stock. If First Horizon’s remaining assets are not sufficient to pay the full liquidating distributions to the holders of all outstanding Series B preferred stock and all Parity Stock, then First Horizon will distribute First Horizon’s assets to those holders pro rata in proportion to the full liquidating distributions to which they would otherwise have received.

First Horizon’s merger or consolidation with one or more other entities or the sale, lease, exchange or other transfer of all or substantially all of First Horizon’s assets (for cash, securities or other consideration) will not be deemed to be a voluntary or involuntary liquidation, dissolution or winding up. If First Horizon enters into any merger or consolidation transaction with or into any other entity and First Horizon is not the surviving entity in such transaction, the Series B preferred stock may be converted into shares of the surviving or successor corporation or the direct or indirect parent of the surviving or successor corporation having terms identical to the terms of the Series B preferred stock.

Because First Horizon is a holding company, First Horizon’s rights and the rights of First Horizon’s creditors and First Horizon’s stockholders, including the holders of the Series B preferred stock, to participate in the distribution of assets of any of First Horizon’s subsidiaries upon that subsidiary’s voluntary or involuntary liquidation, dissolution or winding up will be subject to the prior claims of that subsidiary’s creditors, except to the extent that First Horizon is a creditor with recognized claims against that subsidiary. In addition, holders of the Series B preferred stock (and of depositary shares representing the Series B preferred stock) may be fully subordinated to interests held by the U.S. Government in the event First Horizon enters into a receivership, insolvency, liquidation or similar proceeding.

Conversion Rights

The Series B preferred stock is not convertible into or exchangeable for any other of First Horizon’s property, interests or securities.

Redemption

The Series B preferred stock is not subject to any mandatory redemption, sinking fund or other similar provision.

Neither the holders of Series B preferred stock nor the holders of the related depositary shares have the right to require the redemption or repurchase of the Series B preferred stock. In addition, under the Federal Reserve Board’s risk-based capital rules applicable to bank holding companies, any

176

redemption of the Series B preferred stock is subject to prior approval of the Federal Reserve Board.

Optional Redemption

First Horizon may redeem the Series B preferred stock, in whole or in part, at First Horizon’s option, for cash, on any Dividend Payment Date on or after August 1, 2025, with not less than 30 days’ and not more than 60 days’ notice (“Optional Redemption”), subject to the approval of the appropriate federal banking agency, at the redemption price provided below. Notwithstanding the foregoing, if the closing date occurs after August 1, 2020, the date of the Optional Redemption will be the first Dividend Payment Date that is five (5) years from the closing date. Dividends will not accumulate on those shares of Series B preferred stock on and after the redemption date.

Redemption Following a Regulatory Capital Event

First Horizon may redeem the Series B preferred stock, in whole but not in part, at First Horizon’s option, for cash, at any time within 90 days following a Regulatory Capital Treatment Event, subject to the approval of the appropriate federal banking agency, at the redemption price provided below (“Regulatory Event Redemption”). A “Regulatory Capital Treatment Event” means a good faith determination by First Horizon that, as a result of any: amendment to, clarification of, or change (including any announced prospective change) in, the laws or regulations of the United States or any political subdivision of or in the United States that is enacted or becomes effective after the initial issuance of the Series B preferred stock; proposed change in those laws or regulations that is announced or becomes effective after the initial issuance of the Series B preferred stock; or official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws or regulations that is announced or becomes effective after the initial issuance of the Series B preferred stock there is more than an insubstantial risk that First Horizon will not be entitled to treat the full liquidation value of the Series B preferred stock then outstanding as “Tier 1 Capital” (or its equivalent) for purposes of the capital adequacy laws or regulations of the Federal Reserve Board (or, as and if applicable, the capital adequacy laws or regulations of any successor appropriate federal banking agency), as then in effect and applicable, for as long as any share of Series B preferred stock is outstanding. Dividends will not accumulate on the shares of Series B preferred stock on and after the redemption date.

Redemption Price

The redemption price for any redemption of Series B preferred stock, whether an Optional Redemption or Regulatory Event Redemption, will be equal to $10,000 per share of Series B preferred stock (equivalent to $25 per depositary share), plus any declared and unpaid dividends (without regard to any undeclared dividends) to, but excluding, the date of redemption.

Redemption Procedures

If First Horizon elects to redeem any shares of Series B preferred stock, First Horizon will provide notice to the holders of record of the shares of Series B preferred stock to be redeemed, not less than 30 days and not more than 60 days before the date fixed for redemption thereof (provided, however, that if the shares of Series B preferred stock or the depositary shares representing the shares of Series B preferred stock are held in book-entry form through The Depository Trust Company (“DTC”), First Horizon may give this notice in any manner permitted by DTC). Any notice given as provided in this paragraph will be conclusively presumed to have been duly given, whether or not the holder receives this notice, and any defect in this notice or in the provision of this notice, to any holder of shares of Series B preferred stock designated for redemption will not affect the redemption of any other shares of Series B preferred stock. Each notice of redemption shall state: the redemption date; the redemption price; if fewer than all shares of Series B preferred stock are to be redeemed, the number of shares of Series B preferred stock to be redeemed; and the

177

manner in which holders of Series B preferred stock called for redemption may obtain payment of the redemption price in respect to those shares.

If notice of redemption of any shares of Series B preferred stock has been given and if the funds necessary for such redemption have been set aside by First Horizon in trust for the benefit of the holders of any shares of Series B preferred stock so called for redemption, then from and after the redemption date such shares of Series B preferred stock will no longer be deemed outstanding, all dividends with respect to such shares of Series B preferred stock shall cease to accumulate after the redemption date and all rights of the holders of such shares will terminate, except the right to receive the redemption price, without interest.

In the case of any redemption of only part of the Series B preferred stock at the time outstanding, the shares of Series B preferred stock to be redeemed will be selected either pro rata or by lot or in such other manner as the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) determines to be fair and equitable. Subject to the provisions set forth in this section, the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) will have the full power and authority to prescribe the terms and conditions upon which shares of Series B preferred stock may be redeemed from time to time.

Voting Rights

Registered owners of Series B preferred stock will not have any voting rights, except as set forth below or as otherwise required by applicable law.

Whenever dividends payable on the Series B preferred stock or any other class or series of preferred stock ranking equally with the Series B preferred stock, including the First Horizon series A preferred stock, the First Horizon series C preferred stock and the First Horizon series D preferred stock, as to payment of dividends, and upon which voting rights equivalent to those described in this paragraph have been conferred and are exercisable, have not been declared and paid in an aggregate amount equal to, as to any class or series, the equivalent of at least three or more semi-annual or six or more quarterly Dividend Periods, as applicable, whether or not for consecutive Dividend Periods (a “Nonpayment”), the holders of outstanding shares of the Series B preferred stock voting as a class with holders of shares of any other series of First Horizon preferred stock ranking equally with the Series B preferred stock, including the First Horizon series A preferred stock, the First Horizon series C preferred stock and the First Horizon series D preferred stock, as to payment of dividends, and upon which like voting rights have been conferred and are exercisable (“Voting Parity Stock”), will be entitled to vote for the election of two additional directors of First Horizon board of directors on the terms set forth below (and to fill any vacancies in the terms of such directorships) (the “Preferred Stock Directors”). Holders of all series of First Horizon Voting Parity Stock will vote as a single class. In the event that the holders of the shares of the Series B preferred stock are entitled to vote as described in this paragraph, the number of members of the First Horizon board of directors at the time will be increased by two directors, and the holders of the Series B preferred stock will have the right, as members of that class, as outlined above, to elect two directors at a special meeting called at the request of the holders of record of at least 20% of the aggregate voting power of the Series B preferred stock or any other series of Voting Parity Stock (unless such request is received less than 90 days before the date fixed for First Horizon’s next annual or special meeting of the stockholders, in which event such election shall be held at such next annual or special meeting of the stockholders), provided that the election of any Preferred Stock Directors shall not cause First Horizon to violate the corporate governance requirements of the NYSE (or any other exchange on which First Horizon’s securities may at such time be listed) that listed companies must have a majority of independent directors, and provided further that at no time shall the First Horizon board of directors include more than two Preferred Stock Directors.

When First Horizon has paid full dividends on the Series B preferred stock for the equivalent of at least two semi-annual or four quarterly Dividend Periods, as applicable, following a Nonpayment, the voting rights described above will terminate, except as expressly provided by law. The voting rights described above are subject to re-vesting upon each and every subsequent Nonpayment.

178

Upon termination of the right of the holders of the Series B preferred stock and Voting Parity Stock to vote for Preferred Stock Directors as described above, the term of office of all Preferred Stock Directors then in office elected by only those holders will terminate immediately. Whenever the term of office of the Preferred Stock Directors ends and the related voting rights have expired, the number of directors automatically will be decreased to the number of directors as otherwise would prevail. Any Preferred Stock Director may be removed at any time by the holders of record of a majority of the outstanding shares of the Series B preferred stock (together with holders of any Voting Parity Stock) when they have the voting rights described in this section.

Under regulations adopted by the Federal Reserve Board, if the holders of any series of preferred stock are or become entitled to vote for the election of directors, such series will be deemed a class of voting securities and a company holding 25% or more of the series, or 10% or more if it otherwise exercises a “controlling influence” over First Horizon, will be subject to regulation as a bank holding company under the BHC Act. In addition, at the time the series is deemed a class of voting securities, any other bank holding company will be required to obtain the prior approval of the Federal Reserve Board under the BHC Act to acquire or retain more than 5% of that series. Any other person (other than a bank holding company) will be required to obtain the non-objection of the Federal Reserve Board under the Change in Bank Control Act of 1978, as amended, to acquire or retain 10% or more of that series.

So long as any shares of preferred stock remain outstanding, First Horizon will not, without the affirmative vote or consent of holders of at least 66 2/3% in voting power of the Series B preferred stock and any Voting Parity Stock, voting together as a class, authorize, create or issue any capital stock ranking senior to the Series B preferred stock as to dividends or the distribution of assets upon liquidation, dissolution or winding up, or reclassify any authorized capital stock into any such shares of such capital stock or issue any obligation or security convertible into or evidencing the right to purchase any such shares of capital stock. So long as any shares of the Series B preferred stock remain outstanding, First Horizon will not, without the affirmative vote of the holders of at least 66 2/3% in voting power of the Series B preferred stock, amend, alter or repeal any provision of the Articles of Amendment or First Horizon’s charter, including by merger, consolidation or otherwise, so as to adversely affect the powers, preferences or special rights of the Series B preferred stock.

Notwithstanding the foregoing, none of the following will be deemed to adversely affect the powers, preferences or special rights of the Series B preferred stock: any increase in the amount of authorized common stock or authorized preferred stock, or any increase or decrease in the number of shares of any series of preferred stock, or the authorization, creation and issuance of other classes or series of capital stock, in each case ranking on parity with or junior to the Series B preferred stock as to dividends or distribution of assets upon First Horizon’s liquidation, dissolution or winding up; a merger or consolidation of First Horizon with or into another entity in which the shares of the Series B preferred stock remain outstanding; and a merger or consolidation of First Horizon with or into another entity in which the shares of the Series B preferred stock are converted into or exchanged for preference securities of the surviving entity or any entity, directly or indirectly, controlling such surviving entity and such new preference securities have powers, preferences and special rights that are not materially less favorable than the Series B preferred stock.

Voting Rights under Tennessee Law

Under current provisions of the TBCA, holders of the First Horizon series B preferred stock are entitled to vote separately as a class on certain amendments to the First Horizon charter that would impact the First Horizon series B preferred stock.

Depository, Transfer Agent, and Registrar

Computershare will be the depository, transfer agent, and registrar for the Series B preferred stock.

179

Calculation Agent

First Horizon will appoint a calculation agent for the Series B preferred stock prior to the commencement of the Floating Rate Period.

First Horizon Series C Preferred Stock

General

The “6.60% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series C,” which we refer to in this section as the “Series C preferred stock,” will be designated as one series of First Horizon’s authorized preferred stock. The Series C preferred stock, upon issuance against full payment of the purchase price for the depositary shares, will be fully paid and nonassessable. First Horizon may from time to time, without notice to or the consent of holders of the Series C preferred stock, issue additional shares of Series C preferred stock, provided that if the additional shares are not fungible for U.S. federal income tax purposes with the initial shares of such series, the additional shares shall be issued under a separate CUSIP number. The additional shares would form a single series together with all previously issued shares of Series C preferred stock. In the event First Horizon issues additional shares of Series C preferred stock, First Horizon will cause a corresponding number of additional depositary shares to be issued.

The depository will initially be the sole holder of the Series C preferred stock. The holders of depositary shares will be required to exercise their proportional rights in the shares of Series C preferred stock through the depository, as described in “First Horizon Depositary Shares” below.

Ranking

With respect to the payment of dividends and distributions upon First Horizon’s liquidation, dissolution or winding up, the Series C preferred stock will rank (i) senior to First Horizon common stock and any other class or series of preferred stock that by its terms ranks junior to the Series C preferred stock, (ii) equally with the First Horizon series A preferred stock, the First Horizon series B preferred stock, the First Horizon series D preferred stock and any existing or future series of preferred stock that does not by its terms provide for a junior ranking, and (iii) junior to all existing and future indebtedness and other liabilities and any class or series of preferred stock that expressly provides in the Articles of Amendment creating such preferred stock that such series ranks senior to the Series C preferred stock (subject to any requisite consents prior to issuance).

The Series C preferred stock will not be convertible into, or exchangeable for, shares of any other class or series of capital stock or other securities of First Horizon and will not be subject to any sinking fund or other obligation to redeem or repurchase the Series C preferred stock. The preferred stock is not secured, is not guaranteed by First Horizon or any of its affiliates and is not subject to any other arrangement that legally or economically enhances the ranking of the Series C preferred stock.

Dividends

Holders of the Series C preferred stock will be entitled to receive, only when, as, and if declared by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), out of assets legally available under applicable law for payment, non-cumulative cash dividends based on the liquidation preference of $10,000 per share of Series C preferred stock, and no more, at a rate equal to (1) 6.60% per annum (equivalent to $1.65 per depositary share per annum), for each quarterly Dividend Period occurring from, and including, the original issue date of the Series C preferred stock to, but excluding, May 1, 2026 (the “Fixed Rate Period”), and (2) thereafter, three-month LIBOR plus a spread of 492 basis points per annum, for each quarterly Dividend Period beginning May 1, 2026 (the “Floating Rate Period”). A “Dividend Period” means the period from, and including, each Dividend Payment Date (as defined below) to, but excluding,

180

the next succeeding Dividend Payment Date, except that the initial Dividend Period will be the period from, and including, the last dividend payment date prior to the closing.

When, as, and if declared by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), First Horizon will pay cash dividends on the Series C preferred stock quarterly, in arrears, on February 1, May 1, August 1 and November 1 of each year (each such date, a “Dividend Payment Date”), beginning on the first Dividend Payment Date after completion of the merger. First Horizon will pay cash dividends to the holders of record of shares of the Series C preferred stock as they appear on First Horizon’s stock register on the applicable record date, which shall be the fifteenth calendar day before that Dividend Payment Date or such other record date fixed by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) that is not more than 60 nor less than 10 days prior to such Dividend Payment Date.

If any Dividend Payment Date on or prior to May 1, 2026 is a day that is not a business day (as defined below), then the dividend with respect to that Dividend Payment Date will instead be paid on the immediately succeeding business day, without interest or other payment in respect of such delayed payment. If any Dividend Payment Date after May 1, 2026 is a day that is not a business day, then the Dividend Payment Date will be the immediately succeeding business day unless such day falls in the next calendar month, in which case the Dividend Payment Date will instead be the immediately preceding day that is a business day, and dividends will accumulate to the Dividend Payment Date as so adjusted. A “business day” for the Fixed Rate Period means any weekday in New York, New York that is not a day on which banking institutions in those cities are authorized or required by law, regulation, or executive order to be closed. A “business day” for the Floating Rate Period means any weekday in New York, New York that is not a day on which banking institutions in those cities are authorized or required by law, regulation, or executive order to be closed, and additionally, is a London banking day (as defined below).

First Horizon will calculate dividends on the Series C preferred stock for the Fixed Rate Period on the basis of a 360-day year of twelve 30-day months. First Horizon will calculate dividends on the Series C preferred stock for the Floating Rate Period on the basis of the actual number of days in a Dividend Period and a 360-day year. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward. Dividends on the Series C preferred stock will cease to accumulate after the redemption date, as described below under “—Redemption,” unless First Horizon defaults in the payment of the redemption price of the shares of the Series C preferred stock called for redemption.

Dividends on the Series C preferred stock will not be cumulative or mandatory. If the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) does not declare a dividend on the Series C preferred stock for any Dividend Period prior to the related Dividend Payment Date, that dividend will not accumulate, and First Horizon will have no obligation to pay a dividend for that Dividend Period at any time, whether or not dividends on the Series C preferred stock or any other series of First Horizon preferred stock or common stock are declared for any future Dividend Period.

Dividends on the Series C preferred stock will accumulate from the issue date at the then-applicable dividend rate on the liquidation preference amount of $10,000 per share (equivalent to $25 per depositary share). If First Horizon issues additional shares of the Series C preferred stock, dividends on those additional shares will accumulate from the issue date of those additional shares at the then-applicable dividend rate.

The dividend rate for each Dividend Period in the Floating Rate Period will be determined by the calculation agent using three-month LIBOR as in effect on the second London banking day prior to the beginning of the Dividend Period, which date is the “dividend determination date” for the relevant Dividend Period. The calculation agent then will add three-month LIBOR as determined on the dividend determination date and the applicable spread. Once the dividend rate for the Series C preferred stock is determined, the calculation agent will deliver that information to First Horizon and the transfer agent. Absent manifest error, the calculation agent’s determination of the dividend

rate for a Dividend Period for the Series C preferred stock will be final. A “London banking day” is any day on which commercial banks are open for dealings in deposits in U.S. dollars in the London interbank market.

The term “three-month LIBOR” means the London interbank offered rate for deposits in U.S. dollars for a three month period, as that rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) at approximately 11:00 a.m., London time, on the relevant dividend determination date.

If no offered rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) on the relevant dividend determination date at approximately 11:00 a.m., London time, then the calculation agent, in consultation with First Horizon, will select four major banks in the London interbank market and will request each of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time. If at least two quotations are provided, three-month LIBOR will be the arithmetic average (rounded upward if necessary to the nearest .00001 of 1%) of the quotations provided. Otherwise, the calculation agent in consultation with First Horizon will select three major banks in New York City and will request each of them to provide a quotation of the rate offered by it at approximately 11:00 a.m., New York City time, on the dividend determination date for loans in U.S. dollars to leading European banks for a three month period for the applicable Dividend Period in an amount of at least $1,000,000. If three quotations are provided, three-month LIBOR will be the arithmetic average of the quotations provided. Otherwise, three-month LIBOR for the next Dividend Period will be equal to three-month LIBOR in effect for the then-current Dividend Period or, in the case of the first Dividend Period in the Floating Rate Period, the most recent rate on which three-month LIBOR could have been determined in accordance with the first sentence of this paragraph had the dividend rate been a floating rate during the Fixed Rate Period.

Priority Regarding Dividends

So long as any share of Series C preferred stock remains outstanding, (1) no dividend will be declared and paid or set aside for payment and no distribution will be declared and made or set aside for payment on any Junior Stock (as defined below) (other than a dividend payable solely in shares of Junior Stock or any dividend in connection with the implementation of a shareholder rights plan or the redemption or repurchase of any rights under such a plan); (2) no shares of Junior Stock will be repurchased, redeemed, or otherwise acquired for consideration by First Horizon, directly or indirectly (other than as a result of a reclassification of Junior Stock for or into other Junior Stock, or the exchange for or conversion into Junior Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Junior Stock or pursuant to a contractually binding requirement to buy Junior Stock pursuant to a binding stock repurchase plan existing prior to the most recently completed Dividend Period), nor will any monies be paid to or made available for a sinking fund for the redemption of any such securities by First Horizon; and (3) no shares of Parity Stock (as defined below) will be repurchased, redeemed or otherwise acquired for consideration by First Horizon (other than pursuant to pro rata offers to purchase all, or a pro rata portion, of the Series C preferred stock and such Parity Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Parity Stock or Junior Stock, as a result of a reclassification of Parity Stock for or into other Parity Stock, or by conversion into or exchange for other Parity Stock or Junior Stock), during a Dividend Period, unless, in each case, the full dividends for the most recently completed Dividend Period on all outstanding shares of the Series C preferred stock have been declared and paid in full or declared and a sum sufficient for the payment of those dividends has been set aside. The foregoing limitations do not apply to purchases or acquisitions of First Horizon’s Junior Stock pursuant to any employee or director incentive or benefit plan or arrangement (including any First Horizon employment, severance, or consulting agreements) of First Horizon’s or of any of First Horizon’s subsidiaries.

182

Except as provided below, for so long as any share of Series C preferred stock remains outstanding, First Horizon will not declare, pay, or set aside for payment full dividends on any Parity Stock unless First Horizon has paid in full, or set aside payment in full, in respect of all accumulated dividends for all Dividend Periods for outstanding shares of preferred stock. To the extent that First Horizon declares dividends on the Series C preferred stock and on any Parity Stock but cannot make full payment of such declared dividends, First Horizon will allocate the dividend payments on a pro rata basis among the holders of the shares of Series C preferred stock and the holders of any Parity Stock then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, First Horizon will allocate dividend payments based on the ratio between the then current and unpaid dividend payments due on the shares of Series C preferred stock and (1) in the case of cumulative Parity Stock the aggregate of the accumulated and unpaid dividends due on any such Parity Stock and (2) in the case of non-cumulative Parity Stock, the aggregate of the declared but unpaid dividends due on any such Parity Stock. No interest will be payable in respect of any dividend payment on Series C preferred stock that may be in arrears.

As used in this section, “Junior Stock” means First Horizon common stock and any other class or series of First Horizon’s capital stock over which the Series C preferred stock has preference or priority in the payment of dividends or in the distribution of assets on First Horizon’s liquidation, dissolution or winding up, and “Parity Stock” means the First Horizon series A preferred stock, the First Horizon series B preferred stock, the First Horizon series D preferred stock and any other class or series of First Horizon’s capital stock that ranks on a par with the Series C preferred stock in the payment of dividends and in the distribution of assets on First Horizon’s liquidation, dissolution or winding up, which includes any other class or series of First Horizon’s stock hereafter authorized that ranks on a par with the Series C preferred stock in the payment of dividends and in the distribution of assets on First Horizon’s liquidation, dissolution or winding up.

Subject to the conditions described above, and not otherwise, dividends (payable in cash, stock, or otherwise), as may be determined by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), may be declared and paid on First Horizon’s common stock and any Junior Stock from time to time out of any funds legally available for such payment, and the holders of the Series C preferred stock will not be entitled to participate in those dividends.

Liquidation Rights

Upon First Horizon’s voluntary or involuntary liquidation, dissolution or winding up, the holders of the outstanding shares of Series C preferred stock are entitled to be paid out of First Horizon’s assets legally available for distribution to First Horizon’s shareholders, before any distribution of assets is made to holders of common stock or any other Junior Stock, a liquidating distribution in the amount of a liquidation preference of $10,000 per share (equivalent to $25 per depositary share), plus the sum of any declared and unpaid dividends for prior Dividend Periods prior to the Dividend Period in which the liquidation distribution is made and any declared and unpaid dividends for the then current Dividend Period in which the liquidation distribution is made to the date of such liquidation distribution. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series C preferred stock will have no right or claim to any of First Horizon’s remaining assets.

Distributions will be made only to the extent that First Horizon’s assets are available after satisfaction of all liabilities to depositors, and creditors and subject to the rights of holders of any securities ranking senior to the Series C preferred stock. If First Horizon’s remaining assets are not sufficient to pay the full liquidating distributions to the holders of all outstanding Series C preferred stock and all Parity Stock, then First Horizon will distribute First Horizon’s assets to those holders pro rata in proportion to the full liquidating distributions to which they would otherwise have received.

First Horizon’s merger or consolidation with one or more other entities or the sale, lease, exchange or other transfer of all or substantially all of First Horizon’s assets (for cash, securities or other

183

consideration) will not be deemed to be a voluntary or involuntary liquidation, dissolution or winding up. If First Horizon enters into any merger or consolidation transaction with or into any other entity and First Horizon is not the surviving entity in such transaction, the Series C preferred stock may be converted into shares of the surviving or successor corporation or the direct or indirect parent of the surviving or successor corporation having terms identical to the terms of the Series C preferred stock.

Because First Horizon is a holding company, First Horizon’s rights and the rights of First Horizon’s creditors and First Horizon’s shareholders, including the holders of the Series C preferred stock, to participate in the distribution of assets of any of First Horizon’s subsidiaries upon that subsidiary’s voluntary or involuntary liquidation, dissolution or winding up will be subject to the prior claims of that subsidiary’s creditors, except to the extent that First Horizon is a creditor with recognized claims against that subsidiary. In addition, holders of the Series C preferred stock (and of depositary shares representing the Series C preferred stock) may be fully subordinated to interests held by the U.S. Government in the event First Horizon enters into a receivership, insolvency, liquidation or similar proceeding.

Conversion Rights

The Series C preferred stock is not convertible into or exchangeable for any other of First Horizon’s property, interests or securities.

Redemption

The Series C preferred stock is not subject to any mandatory redemption, sinking fund or other similar provision.

Neither the holders of Series C preferred stock nor the holders of the related depositary shares have the right to require the redemption or repurchase of the Series C preferred stock. In addition, under the Federal Reserve Board’s risk-based capital rules applicable to bank holding companies, any redemption of the Series C preferred stock is subject to prior approval of the Federal Reserve Board.

Optional Redemption

First Horizon may redeem the Series C preferred stock, in whole or in part, at First Horizon’s option, for cash, on any Dividend Payment Date on or after May 1, 2026, with not less than 30 days’ and not more than 60 days’ notice (“Optional Redemption”), subject to the approval of the appropriate federal banking agency, at the redemption price provided below. Dividends will not accumulate on those shares of Series C preferred stock on and after the redemption date.

Redemption Following a Regulatory Capital Event

First Horizon may redeem the Series C preferred stock, in whole but not in part, at First Horizon’s option, for cash, at any time within 90 days following a Regulatory Capital Treatment Event, subject to the approval of the appropriate federal banking agency, at the redemption price provided below (“Regulatory Event Redemption”). A “Regulatory Capital Treatment Event” means a good faith determination by First Horizon that, as a result of any: amendment to, clarification of, or change (including any announced prospective change) in, the laws or regulations of the United States or any political subdivision of or in the United States that is enacted or becomes effective after the initial issuance of the Series C preferred stock; proposed change in those laws or regulations that is announced or becomes effective after the initial issuance of the Series C preferred stock; or official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws or regulations that is announced or becomes effective after the initial issuance of the Series C preferred stock, there is more than an insubstantial risk that First Horizon will not be entitled to treat the full liquidation value of the Series C preferred stock then

184

outstanding as “Tier 1 Capital” (or its equivalent) for purposes of the capital adequacy laws or regulations of the Federal Reserve Board (or, as and if applicable, the capital adequacy laws or regulations of any successor appropriate federal banking agency), as then in effect and applicable, for as long as any share of Series C preferred stock is outstanding. Dividends will not accumulate on the shares of Series C preferred stock on and after the redemption date.

Redemption Price

The redemption price for any redemption of Series C preferred stock, whether an Optional Redemption or Regulatory Event Redemption, will be equal to $10,000 per share of Series C preferred stock (equivalent to $25 per depositary share), plus any declared and unpaid dividends (without regard to any undeclared dividends) to, but excluding, the date of redemption.

Redemption Procedures

If First Horizon elects to redeem any shares of Series C preferred stock, First Horizon will provide notice to the holders of record of the shares of Series C preferred stock to be redeemed, not less than 30 days and not more than 60 days before the date fixed for redemption thereof (provided, however, that if the shares of Series C preferred stock or the depositary shares representing the shares of Series C preferred stock are held in book-entry form through DTC, First Horizon may give this notice in any manner permitted by DTC). Any notice given as provided in this paragraph will be conclusively presumed to have been duly given, whether or not the holder receives this notice, and any defect in this notice or in the provision of this notice, to any holder of shares of Series C preferred stock designated for redemption will not affect the redemption of any other shares of Series C preferred stock. Each notice of redemption shall state: the redemption date; the redemption price; if fewer than all shares of Series C preferred stock are to be redeemed, the number of shares of Series C preferred stock to be redeemed; and the manner in which holders of Series C preferred stock called for redemption may obtain payment of the redemption price in respect to those shares.

If notice of redemption of any shares of Series C preferred stock has been given and if the funds necessary for such redemption have been set aside by First Horizon in trust for the benefit of the holders of any shares of Series C preferred stock so called for redemption, then from and after the redemption date such shares of Series C preferred stock will no longer be deemed outstanding, all dividends with respect to such shares of Series C preferred stock shall cease to accumulate after the redemption date and all rights of the holders of such shares will terminate, except the right to receive the redemption price, without interest.

In the case of any redemption of only part of the Series C preferred stock at the time outstanding, the shares of Series C preferred stock to be redeemed will be selected either pro rata or by lot or in such other manner as the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) determines to be fair and equitable. Subject to the provisions set forth in this section, the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) will have the full power and authority to prescribe the terms and conditions upon which shares of Series C preferred stock may be redeemed from time to time.

Voting Rights

Registered owners of Series C preferred stock will not have any voting rights, except as set forth below or as otherwise required by applicable law.

Whenever dividends payable on the Series C preferred stock or any other class or series of preferred stock ranking equally with the Series C preferred stock, including the First Horizon series A preferred stock, the First Horizon series B preferred stock and the First Horizon series D preferred stock, as to payment of dividends, and upon which voting rights equivalent to those described in this paragraph have been conferred and are exercisable, have not been declared and paid in an

185

aggregate amount equal to, as to any class or series, the equivalent of at least six or more quarterly Dividend Periods, whether or not for consecutive Dividend Periods (a “Nonpayment”), the holders of outstanding shares of the Series C preferred stock voting as a class with holders of shares of any other series of First Horizon preferred stock ranking equally with the Series C preferred stock, including the First Horizon series A preferred stock, the First Horizon series B preferred stock and the First Horizon series D preferred stock, as to payment of dividends, and upon which like voting rights have been conferred and are exercisable (“Voting Parity Stock”), will be entitled to vote for the election of two additional directors of the First Horizon board of directors on the terms set forth below (and to fill any vacancies in the terms of such directorships) (the “Preferred Stock Directors”). Holders of all series of First Horizon Voting Parity Stock will vote as a single class. In the event that the holders of the shares of the Series C preferred stock are entitled to vote as described in this paragraph, the number of members of the First Horizon board of directors at the time will be increased by two directors, and the holders of the Series C preferred stock will have the right, as members of that class, as outlined above, to elect two directors at a special meeting called at the request of the holders of record of at least 20% of the aggregate voting power of the Series C preferred stock or any other series of Voting Parity Stock (unless such request is received less than 90 days before the date fixed for First Horizon’s next annual or special meeting of the shareholders, in which event such election shall be held at such next annual or special meeting of the shareholders), provided that the election of any Preferred Stock Directors shall not cause First Horizon to violate the corporate governance requirements of the NYSE (or any other exchange on which First Horizon’s securities may at such time be listed) that listed companies must have a majority of independent directors, and provided further that at no time shall the First Horizon board of directors include more than two Preferred Stock Directors.

When First Horizon has paid full dividends on the Series C preferred stock for the equivalent of at least four quarterly Dividend Periods following a Nonpayment, the voting rights described above will terminate, except as expressly provided by law. The voting rights described above are subject to re-vesting upon each and every subsequent Nonpayment.

Upon termination of the right of the holders of the Series C preferred stock and Voting Parity Stock to vote for Preferred Stock Directors as described above, the term of office of all Preferred Stock Directors then in office elected by only those holders will terminate immediately. Whenever the term of office of the Preferred Stock Directors ends and the related voting rights have expired, the number of directors automatically will be decreased to the number of directors as otherwise would prevail. Any Preferred Stock Director may be removed at any time by the holders of record of a majority of the outstanding shares of the Series C preferred stock (together with holders of any Voting Parity Stock) when they have the voting rights described in this section.

Under regulations adopted by the Federal Reserve Board, if the holders of any series of preferred stock are or become entitled to vote for the election of directors, such series will be deemed a class of voting securities and a company holding 25% or more of the series, or 10% or more if it otherwise exercises a “controlling influence” over us, will be subject to regulation as a bank holding company under the BHC Act. In addition, at the time the series is deemed a class of voting securities, any other bank holding company will be required to obtain the prior approval of the Federal Reserve Board under the BHC Act to acquire or retain more than 5% of that series. Any other person (other than a bank holding company) will be required to obtain the non-objection of the Federal Reserve Board under the Change in Bank Control Act of 1978, as amended, to acquire or retain 10% or more of that series.

So long as any shares of preferred stock remain outstanding, First Horizon will not, without the affirmative vote or consent of holders of at least 66 2/3% in voting power of the Series C preferred stock and any Voting Parity Stock, voting together as a class, authorize, create or issue any capital stock ranking senior to the Series C preferred stock as to dividends or the distribution of assets upon liquidation, dissolution or winding up, or reclassify any authorized capital stock into any such shares of such capital stock or issue any obligation or security convertible into or evidencing the right to purchase any such shares of capital stock. So long as any shares of the Series C preferred stock remain outstanding, First Horizon will not, without the affirmative vote of the holders of at

186

least 66 2/3% in voting power of the Series C preferred stock, amend, alter or repeal any provision of the Articles of Amendment or the First Horizon charter, including by merger, consolidation or otherwise, so as to affect the powers, preferences or special rights of the Series C preferred stock.

Notwithstanding the foregoing, none of the following will be deemed to affect the powers, preferences or special rights of the Series C preferred stock: any increase in the amount of authorized common stock or authorized preferred stock, or any increase or decrease in the number of shares of any series of preferred stock, or the authorization, creation and issuance of other classes or series of capital stock, in each case ranking on parity with or junior to the Series C preferred stock as to dividends or distribution of assets upon First Horizon’s liquidation, dissolution or winding up; a merger or consolidation of First Horizon with or into another entity in which the shares of the Series C preferred stock remain outstanding; and a merger or consolidation of First Horizon with or into another entity in which the shares of the Series C preferred stock are converted into or exchanged for preference securities of the surviving entity or any entity, directly or indirectly, controlling such surviving entity and such new preference securities have powers, preferences and special rights that are not materially less favorable than the Series C preferred stock.

Voting Rights under Tennessee Law

Under current provisions of the TBCA, holders of the First Horizon series C preferred stock are entitled to vote separately as a class on certain amendments to the First Horizon charter that would impact the First Horizon series C preferred stock.

Depository, Transfer Agent, and Registrar

Computershare will be the depository, transfer agent, and registrar for the Series C preferred stock.

Calculation Agent

First Horizon will appoint a calculation agent for the Series C preferred stock prior to the commencement of the Floating Rate Period.

First Horizon Series D Preferred Stock

General

The “6.100% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series D,” which we refer to in this section as the “Series D preferred stock,” will be designated as one series of First Horizon’s authorized preferred stock. The Series D preferred stock, upon issuance against full payment of the purchase price for the depositary shares, will be fully paid and nonassessable. First Horizon may from time to time, without notice to or the consent of holders of the Series D preferred stock, issue additional shares of Series D preferred stock, provided that if the additional shares are not fungible for U.S. federal income tax purposes with the initial shares of such series, the additional shares shall be issued under a separate CUSIP number. The additional shares would form a single series together with all previously issued shares of Series D preferred stock. In the event First Horizon issues additional shares of Series D preferred stock, it will cause a corresponding number of additional depositary shares to be issued.

The depository will initially be the sole holder of the Series D preferred stock. The holders of depositary shares will be required to exercise their proportional rights in the shares of Series D preferred stock through the depository, as described in “First Horizon Depositary Shares” below.

Ranking

With respect to the payment of dividends and distributions upon First Horizon’s liquidation, dissolution or winding up, the Series D preferred stock will rank (i) senior to First Horizon’s

187

common stock and any other class or series of capital stock that by its terms ranks junior to the Series D preferred stock, (ii) equally with the First Horizon series A preferred stock, the First Horizon series B preferred stock, the First Horizon series C preferred stock and any existing or future series of capital stock that does not by its terms provide for a junior ranking, and (iii) junior to all existing and future indebtedness and other liabilities and any class or series of capital stock that expressly provides in the Articles of Amendment creating such preferred stock that such series ranks senior to the Series D preferred stock (subject to any requisite consents prior to issuance).

The Series D preferred stock will not be convertible into, or exchangeable for, shares of any other class or series of First Horizon capital stock or other securities and will not be subject to any sinking fund or other obligation to redeem or repurchase the Series D preferred stock. The preferred stock is not secured, is not guaranteed by First Horizon or any of First Horizon’s affiliates and is not subject to any other arrangement that legally or economically enhances the ranking of the Series D preferred stock.

Dividends

Holders of the Series D preferred stock will be entitled to receive, only when, as, and if declared by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), out of assets legally available under applicable law for payment, non-cumulative cash dividends based on the liquidation preference of $10,000 per share of Series D preferred stock, and no more, at a rate equal to (1) 6.100 % per annum (equivalent to $1.525 per depositary share per annum), for each semi-annual Dividend Period occurring from, and including, the original issue date of the Series D preferred stock to, but excluding, May 1, 2024 (the “Fixed Rate Period”), and (2) thereafter, three-month LIBOR plus a spread of 385.9 basis points per annum, for each quarterly Dividend Period beginning May 1, 2024 (the “Floating Rate Period”), subject to potential adjustment as provided in clause (iii) of the definition of three-month LIBOR. A “Dividend Period” means the period from, and including, each Dividend Payment Date (as defined below) to, but excluding, the next succeeding Dividend Payment Date, except that the initial Dividend Period will be the period from, and including, the last dividend payment date prior to the closing.

When, as, and if declared by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), First Horizon will pay cash dividends on the Series D preferred stock semi-annually, in arrears, on May 1 and November 1 of each year (each such date, a “Dividend Payment Date”), beginning on the first Dividend Payment Date after completion of the merger and ending on May 1, 2024. From, and including, May 1, 2024, First Horizon will pay cash dividends on the Series D preferred stock quarterly, in arrears, on February 1, May 1, August 1, and November 1, beginning on August 1, 2024, subject to potential adjustment as provided in clause (iii) of the definition of three-month LIBOR. First Horizon will pay cash dividends to the holders of record of shares of the Series D preferred stock as they appear on First Horizon’s stock register on the applicable record date, which shall be the fifteenth calendar day before that Dividend Payment Date or such other record date fixed by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) that is not more than 60 nor less than 10 days prior to such Dividend Payment Date.

If any Dividend Payment Date on or prior to May 1, 2024 is a day that is not a business day (as defined below), then the dividend with respect to that Dividend Payment Date will instead be paid on the immediately succeeding business day, without interest or other payment in respect of such delayed payment. If any Dividend Payment Date after May 1, 2024 is a day that is not a business day, then the Dividend Payment Date will be the immediately succeeding business day unless such day falls in the next calendar month, in which case the Dividend Payment Date will instead be the immediately preceding day that is a business day, and dividends will accumulate to the Dividend Payment Date as so adjusted. A “business day” for the Fixed Rate Period means any weekday in New York, New York that is not a day on which banking institutions in those cities are authorized or required by law, regulation, or executive order to be closed. A “business day” for the Floating Rate Period means any weekday in New York, New York that is not a day on which banking

188

institutions in those cities are authorized or required by law, regulation, or executive order to be closed, and additionally, is a London banking day, which is any day on which commercial banks are open for dealings in deposits in U.S. dollars in the London interbank market.

First Horizon will calculate dividends on the Series D preferred stock for the Fixed Rate Period on the basis of a 360-day year of twelve 30-day months. First Horizon will calculate dividends on the Series D preferred stock for the Floating Rate Period on the basis of the actual number of days in a Dividend Period and a 360-day year, subject to potential adjustment as provided in clause (iii) of the definition of three-month LIBOR. Dollar amounts resulting from that calculation will be rounded to the nearest cent, with one-half cent being rounded upward. Dividends on the Series D preferred stock will cease to accumulate on and after the redemption date, as described below under “—Redemption,” unless First Horizon defaults in the payment of the redemption price of the shares of the Series D preferred stock called for redemption.

Dividends on the Series D preferred stock will not be cumulative or mandatory. If the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) does not declare a dividend on the Series D preferred stock for any Dividend Period prior to the related Dividend Payment Date, that dividend will not accumulate, and First Horizon will have no obligation to pay a dividend for that Dividend Period at any time, whether or not dividends on the Series D preferred stock or any other series of First Horizon’s preferred stock or common stock are declared for any future Dividend Period.

Dividends on the Series D preferred stock will accumulate from the issue date at the then-applicable dividend rate on the liquidation preference amount of $10,000 per share (equivalent to $25 per depositary share). If First Horizon issues additional shares of the Series D preferred stock, dividends on those additional shares will accumulate from the issue date of those additional shares at the then-applicable dividend rate.

The dividend rate for each Dividend Period in the Floating Rate Period will be determined by the calculation agent using three-month LIBOR as in effect on the second London banking day prior to the beginning of the Dividend Period, which date is the “dividend determination date” for the relevant Dividend Period. The calculation agent then will add three-month LIBOR as determined on the dividend determination date and the applicable spread. Once the dividend rate for the Series D preferred stock is determined, the calculation agent will deliver that information to First Horizon and the transfer agent. Absent manifest error, the determination by the calculation agent (or, for the avoidance of doubt, by the IFA in the clause (iii) below) of the dividend rate for a Dividend Period for the Series D preferred stock will be final and binding. A “London banking day” is any day on which commercial banks are open for dealings in deposits in U.S. dollars in the London interbank market.

The term “three-month LIBOR” means, for each dividend determination date related to the Floating-Rate Period, the rate determined by the calculation agent as follows: (i) the London interbank offered rate for deposits in U.S. dollars for a three month period, as that rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) at approximately 11:00 a.m., London time, on the relevant dividend determination date. (ii) If no offered rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) on the relevant dividend determination date at approximately 11:00 a.m., London time, then the calculation agent, in consultation with First Horizon, will select four major banks in the London interbank market and will request each of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time. If at least two quotations are provided, three-month LIBOR will be the arithmetic average (rounded upward if necessary to the nearest .00001 of 1%) of the quotations provided. Otherwise, the calculation agent in consultation with First Horizon will select three major banks in New York City and will request each of them to provide a quotation of the rate offered by it at approximately 11:00 a.m., New York City time, on the dividend determination date for loans in U.S. dollars to leading European banks for a three month period for the applicable Dividend Period in an amount of at least $1,000,000. If three quotations

189

are provided, three-month LIBOR will be the arithmetic average of the quotations provided. Otherwise, if a LIBOR Event (as defined below) has not occurred, three-month LIBOR for the next Dividend Period will be equal to three-month LIBOR in effect for the then-current Dividend Period or, in the case of the first Dividend Period in the Floating Rate Period, the most recent rate on which three-month LIBOR could have been determined in accordance with the first sentence of this paragraph had the dividend rate been a floating rate during the Fixed Rate Period. (iii) Notwithstanding clauses (i) and (ii) above, if First Horizon, in its sole discretion, determine on the relevant dividend determination date that the three-month LIBOR has been permanently discontinued or is no longer viewed as an acceptable benchmark for securities like the Series D preferred stock, and First Horizon has notified the calculation agent (if it is not First Horizon) of such determination (a “LIBOR Event”), then the calculation agent will use, as directed by First Horizon, as a substitute or successor base rate (the “Alternative Rate”) for each future dividend determination date, the alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with market practice regarding a substitute for the three-month LIBOR. As part of such substitution, the calculation agent will, as directed by First Horizon, make such adjustment to the Alternative Rate or the spread thereon, as well as the business day convention, the dividend determination date and related provisions and definitions (“Adjustments”), in each case that are consistent with market practice for the use of such Alternative Rate. Notwithstanding the foregoing, if First Horizon determines that there is no alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with market practice regarding a substitute for three-month LIBOR, First Horizon may, in its sole discretion, appoint an independent financial advisor (“IFA”) to determine an appropriate Alternative Rate and any Adjustments, and the decision of the IFA will be binding on First Horizon, the calculation agent and the holders of the Series D Preferred Stock. If on any dividend determination date during the Floating-Rate Period (which may be the first dividend determination date of the Floating-Rate Period) a LIBOR Event has occurred prior to such Dividend Determination Date and for any reason an Alternative Rate has not been determined or there is no such market practice for the use of such Alternative Rate (and, in each case, an IFA has not determined an appropriate Alternative Rate and Adjustments or an IFA has not been appointed) as of such Dividend Determination Date, then commencing on such Dividend Determination Date the dividend rate, business day convention and manner of calculating dividends applicable during the Fixed-Rate Period will be in effect for the applicable Dividend Period and will remain in effect during the remainder of the Floating-Rate Period.

Priority Regarding Dividends

During any Dividend Period, so long as any share of Series D preferred stock remains outstanding, unless (i) the full dividends for the immediately preceding Dividend Period on all outstanding shares of Series D preferred stock have been paid in full or declared; and funds sufficient for the payment of those dividends set aside, and (ii) First Horizon is not in default on its obligation to redeem any shares of Series D preferred stock that have been called for redemption, (1) no dividend will be declared and paid or set aside for payment and no distribution will be declared and made or set aside for payment on any Junior Stock (as defined below) (other than a dividend payable solely in shares of Junior Stock or any dividend in connection with the implementation of a shareholder rights plan or the redemption or repurchase of any rights under such a plan); (2) no shares of Junior Stock will be repurchased, redeemed, or otherwise acquired for consideration by First Horizon, directly or indirectly (other than as a result of a reclassification of Junior Stock for or into other Junior Stock, or the exchange for or conversion into Junior Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Junior Stock or pursuant to a contractually binding requirement to buy Junior Stock pursuant to a binding stock repurchase plan existing prior to the most recently completed Dividend Period), nor will any monies be paid to or made available for a sinking fund for the redemption of any such securities by us; and (3) no shares of Parity Stock (as defined below) will be repurchased, redeemed or otherwise acquired for consideration by First Horizon (other than pursuant to pro rata offers to purchase all, or a pro rata

190

portion, of the Series D preferred stock and such Parity Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Parity Stock or Junior Stock, as a result of a reclassification of Parity Stock for or into other Parity Stock, or by conversion into or exchange for other Parity Stock or Junior Stock), during a Dividend Period.

The foregoing limitations do not apply to purchases or acquisitions of First Horizon Junior Stock pursuant to any employee or director incentive or benefit plan or arrangement (including any of First Horizon’s employment, severance, or consulting agreements) of First Horizon’s or of any of First Horizon’s subsidiaries.

Except as provided below, for so long as any share of Series D preferred stock remains outstanding, First Horizon will not declare, pay, or set aside for payment full dividends on any Parity Stock unless First Horizon has paid in full, or set aside payment in full, in respect of all accumulated dividends for all Dividend Periods for outstanding shares of preferred stock. To the extent that First Horizon declares dividends on the Series D preferred stock and on any Parity Stock but cannot make full payment of such declared dividends, First Horizon will allocate the dividend payments on a pro rata basis among the holders of the shares of Series D preferred stock and the holders of any Parity Stock then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, First Horizon will allocate dividend payments based on the ratio between the then current and unpaid dividend payments due on the shares of Series D preferred stock and (1) in the case of cumulative Parity Stock the aggregate of the accumulated and unpaid dividends due on any such Parity Stock and (2) in the case of non-cumulative Parity Stock, the aggregate of the declared but unpaid dividends due on any such Parity Stock. No interest will be payable in respect of any dividend payment on Series D preferred stock that may be in arrears.

“Junior Stock” means First Horizon common stock and any other class or series of First Horizon capital stock over which the Series D preferred stock has preference or priority in the payment of dividends or in the distribution of assets on First Horizon’s liquidation, dissolution or winding up, and “Parity Stock” means the First Horizon series A preferred stock, the First Horizon series B preferred stock, the First Horizon series C preferred stock and any other class or series of First Horizon capital stock that ranks on a par with the Series D preferred stock in the payment of dividends and in the distribution of assets on First Horizon’s liquidation, dissolution or winding up, which includes any other class or series of First Horizon’s stock hereafter authorized that ranks on a par with the Series D preferred stock in the payment of dividends and in the distribution of assets on First Horizon’s liquidation, dissolution or winding up.

Subject to the conditions described above, and not otherwise, dividends (payable in cash, stock, or otherwise), as may be determined by the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors), may be declared and paid on First Horizon common stock and any Junior Stock from time to time out of any funds legally available for such payment, and the holders of the Series D preferred stock will not be entitled to participate in those dividends.

Liquidation Rights

Upon First Horizon’s voluntary or involuntary liquidation, dissolution or winding up, the holders of the outstanding shares of Series D preferred stock are entitled to be paid out of First Horizon’s assets legally available for distribution to First Horizon shareholders, before any distribution of assets is made to holders of common stock or any other Junior Stock, a liquidating distribution in the amount of a liquidation preference of $10,000 per share (equivalent to $25 per depositary share), plus the sum of any declared and unpaid dividends for prior Dividend Periods prior to the Dividend Period in which the liquidation distribution is made and any declared and unpaid dividends for the then current Dividend Period in which the liquidation distribution is made to the date of such liquidation distribution. After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series D preferred stock will have no right or claim to any of First Horizon’s remaining assets.

191

In the event that, upon any such voluntary or involuntary liquidation, dissolution or winding up, First Horizon’s available assets are insufficient to pay the amount of the liquidating distributions on all outstanding shares of Series D Preferred Stock and the corresponding amounts payable on all shares of Parity Stock in the distribution of assets upon any such liquidation, dissolution or winding up, then First Horizon will distribute First Horizon’s assets to those holders pro rata in proportion to the full liquidating distributions to which they would otherwise have received.

First Horizon’s merger or consolidation with one or more other entities or the sale, lease, exchange or other transfer of all or substantially all of First Horizon’s assets (for cash, securities or other consideration) will not be deemed to be a voluntary or involuntary liquidation, dissolution or winding up. If First Horizon enters into any merger or consolidation transaction with or into any other entity and First Horizon is not the surviving entity in such transaction, the Series D preferred stock may be converted into or exchanged for preference securities of the surviving entity or any entity, directly or indirectly, controlling such surviving entity, so long as such new preference securities have powers, preferences and special rights that are identical to the powers, preferences and special rights of the Series D preferred stock set forth herein.

Because First Horizon is a holding company, First Horizon’s rights and the rights of First Horizon creditors and First Horizon shareholders, including the holders of the Series D preferred stock, to participate in the distribution of assets of any of First Horizon’s subsidiaries upon that subsidiary’s voluntary or involuntary liquidation, dissolution or winding up will be subject to the prior claims of that subsidiary’s creditors, except to the extent that First Horizon is a creditor with recognized claims against that subsidiary. In addition, holders of the Series D preferred stock (and of depositary shares representing the Series D preferred stock) may be fully subordinated to interests held by the U.S. Government in the event First Horizon enters into a receivership, insolvency, liquidation or similar proceeding.

Conversion Rights

The Series D preferred stock is not convertible into or exchangeable for any other of First Horizon’s property, interests or securities.

Redemption

The Series D preferred stock is not subject to any mandatory redemption, sinking fund or other similar provision.

Neither the holders of Series D preferred stock nor the holders of the related depositary shares have the right to require the redemption or repurchase of the Series D preferred stock. In addition, under the Federal Reserve Board’s risk-based capital rules applicable to bank holding companies, any redemption of the Series D preferred stock is subject to prior approval of the Federal Reserve Board.

Optional Redemption

First Horizon may redeem the Series D preferred stock, in whole or in part, at First Horizon’s option, for cash, on any Dividend Payment Date on or after May 1, 2024, with not less than 30 days’ and not more than 60 days’ notice (“Optional Redemption”), subject to the approval of the appropriate federal banking agency, at the redemption price provided below. Dividends will not accumulate on those shares of Series D preferred stock on and after the redemption date.

Redemption Following a Regulatory Capital Event

First Horizon may redeem the Series D preferred stock, in whole but not in part, at First Horizon’s option, for cash, at any time within 90 days following a Regulatory Capital Treatment Event, subject to the approval of the appropriate federal banking agency, at the redemption price provided below.

192

A “Regulatory Capital Treatment Event” means a good faith determination by First Horizon that, as a result of any: amendment to, clarification of, or change (including any announced prospective change) in, the laws or regulations of the United States or any political subdivision of or in the United States that is enacted or becomes effective after the initial issuance of the Series D preferred stock; proposed change in those laws or regulations that is announced or becomes effective after the initial issuance of the Series D preferred stock; or official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or applying those laws or regulations that is announced or becomes effective after the initial issuance of the Series D preferred stock there is more than an insubstantial risk that First Horizon will not be entitled to treat the full liquidation value of the Series D preferred stock then outstanding as “Tier 1 Capital” (or its equivalent) for purposes of the capital adequacy laws or regulations of the Federal Reserve Board (or, as and if applicable, the capital adequacy laws or regulations of any successor appropriate federal banking agency), as then in effect and applicable, for as long as any share of Series D preferred stock is outstanding. Dividends will not accumulate on the shares of Series D preferred stock on and after the redemption date.

Redemption Price

The redemption price for any redemption of Series D preferred stock, whether an Optional Redemption or Regulatory Event Redemption, will be equal to $10,000 per share of Series D preferred stock (equivalent to $25 per depositary share), plus any declared and unpaid dividends (without regard to any undeclared dividends) to, but excluding, the date of redemption.

Redemption Procedures

If First Horizon elects to redeem any shares of Series D preferred stock, First Horizon will provide notice to the holders of record of the shares of Series D preferred stock to be redeemed, not less than thirty (30) days and not more than sixty (60) days before the date fixed for redemption thereof (provided, however, that if the shares of Series D preferred stock or the depositary shares representing the shares of Series D preferred stock are held in book-entry form through DTC, First Horizon may give this notice in any manner permitted by DTC). Any notice given as provided in this paragraph will be conclusively presumed to have been duly given, whether or not the holder receives this notice, and any defect in this notice or in the provision of this notice, to any holder of shares of Series D preferred stock designated for redemption will not affect the redemption of any other shares of Series D preferred stock. Each notice of redemption shall state: the redemption date; the redemption price; if fewer than all shares of Series D preferred stock are to be redeemed, the number of shares of Series D preferred stock to be redeemed; and the manner in which holders of Series D preferred stock called for redemption may obtain payment of the redemption price in respect to those shares.

If notice of redemption of any shares of Series D preferred stock has been given and if the funds necessary for such redemption have been set aside by First Horizon in trust for the benefit of the holders of any shares of Series D preferred stock so called for redemption, then from and after the redemption date such shares of Series D preferred stock will no longer be deemed outstanding, all dividends with respect to such shares of Series D preferred stock shall cease to accumulate after the redemption date and all rights of the holders of such shares will terminate, except the right to receive the redemption price, without interest.

In the case of any redemption of only part of the Series D preferred stock at the time outstanding, the shares of Series D preferred stock to be redeemed will be selected either pro rata or by lot or in such other manner as the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) determines to be fair and equitable. Subject to the provisions set forth herein, the First Horizon board of directors (or a duly authorized committee of the First Horizon board of directors) will have the full power and authority to prescribe the terms and conditions upon which shares of Series D preferred stock may be redeemed from time to time.

193

Voting Rights

Registered owners of Series D preferred stock will not have any voting rights, except as set forth below or as otherwise required by applicable law.

Whenever dividends payable on the Series D preferred stock or any other class or series of preferred stock ranking equally with the Series D preferred stock, including the First Horizon series A preferred stock, the First Horizon series B preferred stock and the First Horizon series C preferred stock, as to payment of dividends, and upon which voting rights equivalent to those described in this paragraph have been conferred and are exercisable, have not been declared and paid in an aggregate amount equal to, as to any class or series, the equivalent of at least three Fixed Rate Periods or at least six Floating Rate Periods, whether or not for consecutive Dividend Periods (a “Nonpayment”), the holders of outstanding shares of the Series D preferred stock voting as a class with holders of shares of any other series of First Horizon preferred stock ranking equally with the Series D preferred stock, including the First Horizon series A preferred stock, the First Horizon series B preferred stock and the First Horizon series C preferred stock, as to payment of dividends, and upon which like voting rights have been conferred and are exercisable (“Voting Parity Stock”), will be entitled to vote for the election of two additional directors of the First Horizon board of directors on the terms set forth below (and to fill any vacancies in the terms of such directorships) (the “Preferred Stock Directors”). Holders of all series of First Horizon Voting Parity Stock will vote as a single class. In the event that the holders of the shares of the Series D preferred stock are entitled to vote as described in this paragraph, the number of members of the First Horizon board of directors at the time will be increased by two directors, and the holders of the Series D preferred stock will have the right, as members of that class, as outlined above, to elect two directors at a special meeting called at the request of the holders of record of at least 20% of the aggregate voting power of the Series D preferred stock or any other series of Voting Parity Stock (unless such request is received less than 90 days before the date fixed for First Horizon’s next annual or special meeting of the shareholders, in which event such election shall be held at such next annual or special meeting of the shareholders), provided that the election of any Preferred Stock Directors shall not cause First Horizon to violate the corporate governance requirements of the NYSE (or any other exchange on which First Horizon’s securities may at such time be listed) that listed companies must have a majority of independent directors, and provided further that at no time shall the First Horizon board of directors include more than two Preferred Stock Directors.

The Preferred Stock Directors elected at any such special meeting will hold office until First Horizon’s next annual meeting of the shareholders unless they have been previously terminated or removed pursuant to the First Horizon charter. In case any vacancy in the office of a Preferred Stock Director occurs (other than prior to the initial election of the Preferred Stock Directors), the vacancy may be filled by the written consent of the Preferred Stock Director remaining in office, or if none remains in office, by the vote of the holders of the Series D preferred stock (together with holders of any Voting Parity Stock) to serve until First Horizon’s next annual meeting of the shareholders.

When First Horizon has paid full dividends on the Series D preferred stock for the equivalent of at least two Fixed Rate Periods or at least four Floating Rate Periods following a Nonpayment, the voting rights described above will terminate, except as expressly provided by law. The voting rights described above are subject to re-vesting upon each and every subsequent Nonpayment.

Upon termination of the right of the holders of the Series D preferred stock and Voting Parity Stock to vote for Preferred Stock Directors as described above, the term of office of all Preferred Stock Directors then in office elected by only those holders will terminate immediately. Whenever the term of office of the Preferred Stock Directors ends and the related voting rights have expired, the number of directors automatically will be decreased to the number of directors as otherwise would prevail. Any Preferred Stock Director may be removed at any time by the holders of record of a majority of the outstanding shares of the Series D preferred stock (together with holders of any Voting Parity Stock) when they have the voting rights described in this section.

194

Under regulations adopted by the Federal Reserve Board, if the holders of any series of preferred stock are or become entitled to vote for the election of directors, such series will be deemed a class of voting securities and a company holding 25% or more of the series, or 10% or more if it otherwise exercises a “controlling influence” over First Horizon, will be subject to regulation as a bank holding company under the BHC Act. In addition, at the time the series is deemed a class of voting securities, any other bank holding company will be required to obtain the prior approval of the Federal Reserve Board under the BHC Act to acquire or retain more than 5% of that series. Any other person (other than a bank holding company) will be required to obtain the non-objection of the Federal Reserve Board under the Change in Bank Control Act of 1978, as amended, to acquire or retain 10% or more of that series.

So long as any shares of preferred stock remain outstanding, First Horizon will not, without the affirmative vote or consent of holders of at least 66 2/3% in voting power of the Series D preferred stock and any Voting Parity Stock, voting together as a class, authorize, create or issue any capital stock ranking senior to the Series D preferred stock as to dividends or the distribution of assets upon liquidation, dissolution or winding up, or reclassify any authorized capital stock into any such shares of such capital stock or issue any obligation or security convertible into or evidencing the right to purchase any such shares of capital stock. So long as any shares of the Series D preferred stock remain outstanding, First Horizon will not, without the affirmative vote of the holders of at least 66 2/3% in voting power of the Series D preferred stock, amend, alter or repeal any provision of the Articles of Amendment or First Horizon’s charter, including by merger, consolidation or otherwise, so as to affect the powers, preferences or special rights of the Series D preferred stock.

Notwithstanding the foregoing, none of the following will be deemed to affect the powers, preferences or special rights of the Series D preferred stock: any increase in the amount of authorized common stock or authorized preferred stock, or any increase or decrease in the number of shares of any series of preferred stock, or the authorization, creation and issuance of other classes or series of capital stock, in each case ranking on parity with or junior to the Series D preferred stock as to dividends or distribution of assets upon First Horizon’s liquidation, dissolution or winding up; a merger or consolidation of First Horizon with or into another entity in which the shares of the Series D preferred stock remain outstanding; and a merger or consolidation of First Horizon with or into another entity in which the shares of the Series D preferred stock are converted into or exchanged for preference securities of the surviving entity or any entity, directly or indirectly, controlling such surviving entity, so long as such new preference securities have powers, preferences and special rights that are identical to the powers, preferences and special rights of the Series D preferred stock.

Voting Rights under Tennessee Law

Under current provisions of the TBCA, holders of the First Horizon series D preferred stock are entitled to vote separately as a class on certain amendments to the First Horizon charter that would impact the First Horizon series D preferred stock.

Depository, Transfer Agent, and Registrar

Computershare will be the depository, transfer agent, and registrar for the Series D preferred stock.

Calculation Agent

First Horizon will initially act as calculation agent unless First Horizon appoints a calculation agent for the Series D preferred stock prior to the commencement of the Floating Rate Period.

Information Rights

During any period in which First Horizon is not subject to Section 13 or 15(d) of the Exchange Act and any shares of Series D preferred stock are outstanding, First Horizon will use commercially

195

reasonable efforts to provide any requesting beneficial owner a copy of First Horizon’s most recently filed “Consolidated Financial Statements for Holding Companies—FR Y-9C” and “Consolidated Reports of Condition and Income for a Bank With Domestic Offices Only-FFIEC 041,” in each case or any applicable successor form. Any such request must be made in writing addressed to First Horizon National Corporation, 165 Madison Avenue, Memphis, Tennessee 38103, Attention: Chief Financial Officer.

First Horizon Depositary Shares

General

IBKC has issued fractional interests in shares of each series of IBKC preferred stock in the form of depositary shares, which upon the effective time will represent a corresponding interest in shares of rollover First Horizon preferred stock. The shares of rollover First Horizon preferred stock will be deposited with Computershare, as depository, under the applicable deposit agreement. First Horizon will assume the obligations of IBKC under the deposit agreements upon the completion of the merger. First Horizon will instruct the depository to treat the rollover First Horizon preferred stock received by it in exchange for shares of IBKC preferred stock as newly deposited securities as provided in the applicable deposit agreement. The IBKC depositary shares will then become rollover First Horizon depositary shares and thereafter represent shares of rollover First Horizon preferred stock.

Each rollover First Horizon depositary share represents a 1/400th interest in a share of the applicable series of rollover First Horizon preferred stock, and will be evidenced by depositary receipts. Subject to the terms of the applicable deposit agreement, the rollover First Horizon depositary shares will be entitled to all the powers, preferences and special rights of the rollover First Horizon preferred stock, as applicable, in proportion to the applicable fraction of a share of rollover First Horizon preferred stock those rollover First Horizon depositary shares represent.

References to “holders” of rollover First Horizon depositary shares mean those who own rollover First Horizon depositary shares registered in their own names on the books that First Horizon or the depository maintain for this purpose. DTC is the only registered holder of the depositary receipts representing the IBKC depositary shares and, following the closing, will be the only registered holder of the depositary shares representing the rollover First Horizon depositary shares. References to “holders” of depositary shares do not include indirect holders who own beneficial interests in depositary shares registered in street name or issued in book-entry form through DTC.

Listing

First Horizon plans to file an application to list the rollover First Horizon depositary shares on the NYSE under the symbols “FHN PR B,” “FHN PR C” and “FHN PR D,” respectively. If the application is approved, trading of the rollover First Horizon depositary shares on the NYSE is expected to begin within thirty (30) days after the date of initial issuance of the rollover First Horizon depositary shares. The rollover First Horizon preferred stock will not be listed, and First Horizon does not expect that there will be any trading market for the rollover First Horizon preferred stock except as represented by depositary shares.

Dividends and Other Distributions

Each dividend payable on a rollover First Horizon depositary share will be in an amount equal to 1/400th of the dividend declared and payable on each share of rollover First Horizon preferred stock.

The depository will distribute all dividends and other cash distributions received on the rollover First Horizon preferred stock to the holders of record of the depositary receipts in proportion to the number of rollover First Horizon depositary shares held by each holder. In the event of a distribution other than in cash, the depository will distribute property received by it to the holders

196

of record of the depositary receipts in proportion to the number of First Horizon depositary shares held by each holder, unless the depository determines that this distribution is not feasible, in which case the depository may, with First Horizon’s approval, adopt a method of distribution that it deems equitable and practicable, including the sale of the property (in a commercially reasonable manner) and distribution of the net proceeds of that sale to the holders of the depositary receipts.

If the calculation of a dividend or other cash distribution results in an amount that is a fraction of a cent and that fraction is equal to or greater than $0.005, the depository will round that amount up to the next highest whole cent and will request that First Horizon pay the resulting additional amount to the depository for the relevant dividend or other cash distribution. If the fractional amount is less than $0.005, the depository will disregard that fractional amount and add such amount to, and treat it as a part of, the next succeeding distribution.

Record dates for the payment of dividends and other matters relating to the rollover First Horizon depositary shares will be the same as the corresponding record dates for the applicable series of rollover First Horizon preferred stock.

The amount paid as dividends or otherwise distributable by the depository with respect to the rollover First Horizon depositary shares or the underlying rollover First Horizon preferred stock will be reduced by any amounts required to be withheld by First Horizon or the depository on account of taxes or other governmental charges. The depository may refuse to make any payment or distribution, or any transfer, exchange, or withdrawal of any rollover First Horizon depositary shares or the shares of the rollover First Horizon preferred stock until such taxes or other governmental charges are paid.

Liquidation Preference

In the event of First Horizon’s liquidation, dissolution or winding up, a holder of rollover First Horizon depositary shares will receive the fraction of the liquidation preference accorded each share of underlying rollover First Horizon preferred stock represented by the depositary shares.

First Horizon’s merger or consolidation with one or more other entities or the sale, lease, exchange or other transfer of all or substantially all of First Horizon’s assets (for cash, securities or other consideration) will not be deemed to be a voluntary or involuntary liquidation, dissolution or winding up.

Redemption of Depositary Shares

If First Horizon redeems any series of rollover First Horizon preferred stock, in whole or in part, rollover First Horizon depositary shares also will be redeemed with the proceeds received by the depository from the redemption of the rollover First Horizon preferred stock held by the depository. The redemption price per rollover First Horizon depositary share will be 1/400th of the redemption price per share payable with respect to the rollover First Horizon preferred stock (or $25 per depositary share), plus, as applicable, any accumulated and unpaid dividends on the shares of the rollover First Horizon preferred stock called for redemption for the then-current dividend period to, but excluding, the redemption date, without accumulation of any undeclared dividends.

If First Horizon redeems shares of the rollover First Horizon preferred stock held by the depository, the depository will redeem, as of the same redemption date, the number of rollover First Horizon depositary shares representing those shares of the rollover First Horizon preferred stock so redeemed. If First Horizon redeems less than all of the outstanding rollover First Horizon depositary shares, the rollover First Horizon depositary shares to be redeemed will be selected either pro rata or by lot. In any case, the depository will redeem rollover First Horizon depositary shares only in increments of 400 rollover First Horizon depositary shares and multiples thereof. The depository will provide notice of redemption to record holders of the depositary receipts not less than 30 and not more than 60 days prior to the date fixed for redemption of the applicable series of rollover First Horizon preferred stock and the related rollover First Horizon depositary shares.

197

Voting

Because each rollover First Horizon depositary share represents a 1/400th ownership interest in a share of rollover First Horizon preferred stock, holders of depositary receipts will be entitled to vote 1/400th of a vote per rollover First Horizon depositary share under those limited circumstances in which holders of the rollover First Horizon preferred stock are entitled to vote.

When the depository receives notice of any meeting at which the holders of the rollover First Horizon preferred stock are entitled to vote, the depository will provide the information contained in the notice to the record holders of the rollover First Horizon depositary shares relating to the rollover First Horizon preferred stock. Each record holder of the First Horizon depositary shares on the record date, which will be the same date as the record date for the rollover First Horizon preferred stock, may instruct the depository to vote the amount of the rollover First Horizon preferred stock represented by the holder’s rollover First Horizon depositary shares. To the extent possible, the depository will vote the amount of the rollover First Horizon preferred stock represented by depositary shares in accordance with the instructions it receives. First Horizon will agree to take all reasonable actions that the depository determines are necessary to enable the depository to vote as instructed. If the depository does not receive specific instructions from the holders of any rollover First Horizon depositary shares representing the rollover First Horizon preferred stock, it will abstain from voting with respect to such shares (but shall appear at the meeting with respect to such shares unless directed to the contrary).

Withdrawal of Rollover First Horizon Preferred Stock

Upon surrender of rollover First Horizon depositary shares at the principal office of the depository, upon payment of any unpaid amount due the depository, and subject to the terms of the applicable deposit agreement, the owner of the rollover First Horizon depositary shares evidenced thereby is entitled to delivery of the number of shares of the applicable series of rollover First Horizon preferred stock and all money and other property, if any, represented by such rollover First Horizon depositary shares. Only whole shares of rollover First Horizon preferred stock may be withdrawn. If the rollover First Horizon depositary shares surrendered by the holder in connection with withdrawal exceed the number of First Horizon depositary shares that represent the number of whole shares of rollover First Horizon preferred stock to be withdrawn, the depository will deliver to that holder at the same time a new depositary receipt evidencing the excess number of First Horizon depositary shares. Holders of rollover First Horizon preferred stock thus withdrawn will not thereafter be entitled to deposit such shares under the applicable deposit agreement or to receive rollover First Horizon depositary shares therefor.

Resignation and Removal of the Depository

The depository may resign at any time by delivering to First Horizon notice of its election to resign. First Horizon may also remove or replace a depository at any time. Any resignation or removal will take effect upon the earlier of the appointment of a successor depository and thirty (30) days following such notice. First Horizon will appoint a successor depository within thirty (30) days after delivery of the notice of resignation or removal. The successor must be authorized under applicable laws to exercise the powers of a transfer agent and subject to supervision or examination by federal or state authorities, have its principal office in the United States, and have a combined capital and surplus of at least $50 million.

Miscellaneous

The depository will forward to the holders of rollover First Horizon depositary shares any reports and communications from First Horizon with respect to the underlying rollover First Horizon preferred stock. Neither First Horizon nor the depository will be liable if any law or any circumstances beyond their control prevent or delay them from performing their obligations under the applicable deposit agreement. The obligations of First Horizon and a depository under the

198

applicable deposit agreement will be limited to performing their duties without bad faith, gross negligence or willful misconduct. Neither First Horizon nor a depository must prosecute or defend any legal proceeding with respect to any rollover First Horizon depositary shares or the underlying rollover First Horizon preferred stock unless they are furnished with satisfactory indemnity. Both First Horizon and the depository may rely on the written advice of counsel or accountants, and on documents they believe in good faith to be genuine and signed by a proper party. In the event a depository receives conflicting claims, requests or instructions from First Horizon and any holders of rollover First Horizon depositary shares, the depository will be entitled to act on the claims, requests or instructions received from First Horizon.

The exclusive forum clause in each deposit agreement provides that any action or proceeding arising out of or relating in any way to such deposit agreement may only be brought in a state court located in the State of New York or in the United States District Court for the Southern District of New York. To the fullest extent permitted by law, the exclusive forum clause in the applicable deposit agreement will apply to any action or proceeding described in the prior sentence that arises or purports to arise under the federal securities laws, including claims brought under the Securities Act and Exchange Act. To the extent these exclusive forum provisions restrict the courts in which holders of rollover First Horizon depositary shares may bring claims arising under the federal securities laws, there is uncertainty as to whether a court would enforce such provisions.

199

COMPARISON OF SHAREHOLDERS’ RIGHTS

If the merger is completed, IBKC common shareholders will receive shares of First Horizon common stock in the merger and IBKC preferred shareholders will receive shares of the applicable series of the rollover First Horizon preferred stock, and in both cases they will cease to be shareholders of IBKC. First Horizon is organized under the laws of the State of Tennessee. IBKC is organized under the laws of the State of Louisiana. The following is a summary of certain material differences between (1) the current rights of IBKC shareholders under the IBKC articles of incorporation and bylaws and Louisiana law and (2) the current rights of First Horizon shareholders under the First Horizon charter and bylaws and Tennessee law.

The rollover First Horizon preferred stock will have terms that are the same as the terms of the applicable series of outstanding IBKC preferred stock, taking into account that IBKC will not be the surviving entity in the merger and, with respect to the IBKC series B preferred stock, taking into account that the optional redemption date for the First Horizon series B preferred stock may be deferred until the first dividend payment date that is at least five (5) years from the closing date. For more information, see “Description of Rollover First Horizon Preferred Stock” beginning on page 172.

The following summary is not a complete statement of the rights of shareholders of the two companies or a complete description of the specific provisions referred to below. The summary is qualified in its entirety by reference to IBKC’s and First Horizon’s governing documents, which we urge you to read carefully and in their entirety. Copies of First Horizon’s and IBKC’s governing documents have been filed with the SEC. See “Where You Can Find More Information” beginning on page 218.

First Horizon shareholders do not have the right to cumulate their votes with respect to the election of directors.
|  | Except as otherwise required by the LBCA or IBKC’s articles of incorporation or bylaws, all matters brought before IBKC’s common shareholders, other than the election of directors, require the affirmative vote of at least a majority of the votes cast. Under IBKC’s bylaws, directors are elected by plurality vote. |  | Except as otherwise required by the TBCA or First Horizon’s charter, all matters brought before First Horizon’s shareholders, other than the election of directors, require the affirmative vote of at least a majority of the votes cast. Under the TBCA, directors may be elected by plurality vote. However, as discussed below, First Horizon’s charter establishes a majority-of-votes-cast standard, and First Horizon has adopted a director resignation policy which requires a director elected with less than a majority vote to tender his or her resignation for the board’s consideration.
Rights of Preferred Stock: |  | IBKC’s articles of incorporation provide that its board of directors shall have the full authority permitted by law to divide the authorized and unissued shares of preferred stock into series and to fix by resolution full, limited, multiple or fractional, or no voting rights, and such designations, preferences, qualifications, privileges, limitations, restrictions, options, conversion rights, and other special or relative rights of the preferred stock or any series thereof that may be desired. Prior to the issuance of any series of preferred stock, the board of directors will adopt resolutions creating and designating the series as a series of preferred stock, and the articles of amendment setting forth the terms of such series will be filed with the Secretary of State of Louisiana. |  | First Horizon’s charter provides that its board of directors is authorized, in respect of each series of preferred stock that may be issued, to fix the number of shares of each such series and to determine the voting powers (if any), designation, preferences and relative, participating, optional and/or other special rights, and the qualifications, limitations or restrictions thereof, including to provide that any class or series of preferred stock be subject to redemption, entitled to receive dividends, entitled to rights upon the dissolution or convertible into, or exchangeable for, shares of any other class or series of securities. Prior to the issuance of any series of preferred stock, the board of directors will adopt resolutions creating and designating the series as a series of preferred stock, and the articles of amendment to the charter setting forth the preferences, rights, limitations and other terms of such series will be filed with the Secretary of State of Tennessee.

Size of Board of Directors |  | IBKC’s bylaws currently provide that its board of directors shall consist of eleven directors. Any change in the number of directors on the IBKC board of directors requires an amendment to the bylaws. |  | First Horizon’s bylaws provide that its board of directors shall consist of fourteen directors until directors are elected at the 2020 Annual Meeting of shareholders; after that election, the board of directors shall consist of twelve directors. Any change in the number of directors on the First Horizon board of directors requires an amendment to the bylaws and the affirmative vote of a majority of the directors then in office. Upon completion of the merger, the size of First Horizon board of directors will increase to seventeen directors.
Classes of Directors |  | The IBKC board of directors is divided into three classes. The members of each class will be elected for a term of three years and only one class of directors will be elected annually. Thus, it would take at least two annual elections to replace a majority of IBKC’s board of directors. |  | First Horizon’s charter does not separate the directors into classes with staggered, multi-year terms of office. Instead, directors are elected to one-year terms.
Director Eligibility and Mandatory Retirement |  | IBKC’s bylaws provide that no person shall be eligible for nomination or election as a director who shall have attained the age of 76 or who, while a director of IBKC, was absent during his or her annual term of office from more than one-third of the aggregate number of meetings of the IBKC board of directors and committees of which he or she was a member, unless the failure to so attend resulted from illness or other reason determined by IBKC’s Nominating and Corporate Governance Committee to excuse such failure to attend. |  | First Horizon’s bylaws provide that any First Horizon director who is 72 on or before the last day of the term for which he or she was elected shall not be nominated for re-election. Without amending the bylaws, each year the First Horizon board of directors may waive this age limit for any director for an additional term if it determines such waiver to be beneficial to the board and in the best interest of First Horizon. A First Horizon director who leaves his or her principal position (other than by promotion) while serving on the First Horizon Board is expected to tender his or her resignation for consideration by the Board. The tender may be accepted or rejected by the Board based on the Board’s determinations of certain factors specified in First Horizon’s bylaws.
Election of Directors |  | Under IBKC’s bylaws, directors are elected by a plurality of the votes cast by the shareholders entitled to vote in the election. |  | First Horizon’s charter provides that each director will be elected by the affirmative vote of a majority of the votes cast with respect to the director in an uncontested election of directors at a meeting at which a quorum is present. For this purpose, the

202

|  | IBKC |  | First Horizon
|  |  |  | “affirmative vote of a majority of the votes cast” means that the number of votes cast “for” exceeds the number of votes cast “against” that director. Abstentions and broker non-votes will normally have no effect on the results of director elections. If an election is contested, the directors will be elected by the vote of a plurality of the votes cast by the shares entitled to vote in the election at any such meeting. First Horizon has a director resignation policy that provides that, in an uncontested election, a director who does not receive the affirmative vote of a majority of the votes cast with respect to his or her election must tender his or her resignation. First Horizon’s Nominating & Corporate Governance Committee must then promptly consider the resignation offer and a range of possible responses and make a recommendation to the board of directors. The board of directors will act on the Nominating & Corporate Governance Committee’s recommendation within 90 days following certification of the shareholder vote.
Removal of Directors |  | Under IBKC’s articles of incorporation and bylaws, directors may be removed, without cause, by the affirmative vote of not less than 75% of the total votes eligible to be cast by common shareholders at a shareholder meeting called expressly for such purpose. |  | Under First Horizon’s charter and bylaws, directors may be removed by the shareholders only for cause by the affirmative vote of the holders of at least a majority of the voting power of all outstanding voting stock.
|  | In addition, under IBKC’s articles of incorporation, directors may be removed, with cause, by the affirmative vote of not less than a majority of the total votes eligible to be cast by common shareholders. Cause for removal shall exist only if the director whose removal is proposed has been (i) declared incompetent by an order of a court, (ii) convicted of a felony or of an offense punishable by imprisonment for a term of more than one year by a court of competent jurisdiction, or (iii) |  |

203

|  | IBKC |  | First Horizon
|  | deemed liable by a court of competent jurisdiction for gross negligence or misconduct in the performance of such director’s duties to IBKC. |  |
Filing Vacancies on the Board of Directors |  | IBKC’s articles of incorporation and bylaws provide that vacancies on IBKC’s board of directors for any reason (including any vacancy resulting from an increase in the number of directors, or from the failure of the shareholders to elect the full number of authorized directors) may be filled by the affirmative vote of a majority of the remaining directors for an unexpired term; provided, that the shareholders will have the right, at a special meeting called for such purpose prior to action by the board of directors, to fill the vacancy. |  | First Horizon’s charter and bylaws provide that vacancies on the First Horizon board of directors for any reason (except removal from office) and newly created directorships resulting from an increase in the number of directors may only be filled by the directors. Any vacancy on the board of directors resulting from a director being removed from office may be filled by the affirmative vote the holders of at least a majority of the voting power of all outstanding voting stock or, if the shareholders do not so fill such vacancy, by a majority of the directors then in office.
|  |  |  | The bylaws provide that directors elected to fill a newly created directorship or other vacancy will hold office for a term expiring at the next shareholders’ meeting at which directors are elected and until such director’s successor has been duly elected and qualified.
Special Meetings of Stockholders / Shareholders |  | The LBCA provides that a Louisiana corporation shall hold a special shareholder meeting if shareholders holding at least 10% of all votes entitled to be cast on an issue deliver an appropriate written demand. In addition, under IBKC’s articles of incorporation, special meetings of the shareholders may be called by the board of directors, chairman of the board or president, or, under certain circumstances, by the holders of a class or series of IBKC preferred shares. |  | Under First Horizon’s bylaws, a special meeting of shareholders may be called by the Chairman of the board of directors or the Secretary and will be called by the Chairman of the board of directors or Secretary at the request, in writing, of a majority of the board of directors. Under the TBCA, the holders of at least 10% of the votes entitled to be cast may call a special meeting of shareholders.
Quorum |  | Under IBKC’s bylaws, the presence in person or by proxy of the holders of a majority of the total voting power constitutes a quorum at all meetings of shareholders. If a quorum is not present or represented at a meeting of shareholders, those present may adjourn the meeting to such time and place as they may determine. In the case of any meeting called for the election of directors, those who attend |  | Under First Horizon’s bylaws, the presence in person or by proxy of holders of a majority of the shares entitled to vote at a meeting of First Horizon shareholders constitutes a quorum for such meeting of shareholders. If a quorum is not present or represented at a meeting of shareholders, the holders of a majority of the shares entitled to vote at the meeting who are present or

204

|  | IBKC |  | First Horizon
|  | the second of such adjourned meetings, although less than a quorum as described above, shall nevertheless constitute a quorum for the purpose of electing directors. |  | represented at the meeting may adjourn the meeting until a quorum is obtained, from time to time. The chairman of the meeting has the power to adjourn the meeting from time to time, whether or not a quorum is obtained.
Notice of Stockholder / Shareholder Meetings |  | IBKC’s bylaws provide that IBKC must give written notice at least ten days and not more than sixty days prior to the day fixed for a shareholder meeting to each shareholder entitled to vote at such meeting. The notice must state the time and place of the meeting. If the meeting is a special meeting of the shareholders, the notice of the meeting must state the purposes of the meeting. |  | First Horizon’s bylaws provide that First Horizon must give written notice between ten days and two months before any shareholder meeting to each shareholder entitled to vote at such meeting. The notice must state the date, time and place of the meeting. If the meeting is a special meeting of the shareholders, the notice of the meeting must state the purposes of the meeting and the person or persons calling the meeting.
Advance Notice of Stockholder / Shareholder Proposals and Nominations |  | IBKC’s articles of incorporation establish advance notice requirements for shareholder proposals and the nomination (other than by or at the direction of IBKC’s board of directors or one of its committees) of candidates for election as directors. A shareholder of IBKC wishing to nominate a person as a candidate for election to the board of directors must submit the nomination in writing at least sixty days before the one year anniversary of the most recent annual meeting of shareholders, together with (a) as to each person the shareholder proposes to nominate, and as to the shareholder submitting the notice, (i) their names, ages, business and residence addresses, (ii) principal occupation or employment, (iii) stockholdings, and (iv) other information required by SEC proxy rules; and (b) to the extent known, (i) the name and address of other shareholders supporting the nominee(s), and (ii) their stockholdings. Nominations that are not made in accordance with the foregoing provisions may be ruled out of order. In addition, a shareholder intending to make a proposal for consideration at a regularly scheduled annual meeting that is not intended to |  | First Horizon’s bylaws provide that, for a proposal relating to the nomination of a director to be elected to the board of directors or to bring a proposal at an annual or special meeting, the shareholder must deliver timely written notice to First Horizon’s secretary before the meeting. To be considered timely, the notice must be received by the secretary not less than ninety (90) days or more than one hundred twenty (120) days prior to the date of the meeting, provided, however, if fewer than one hundred (100) days’ notice or prior public disclosure of the date of the meeting is given to shareholders, notice by the shareholders to be timely must be delivered or received not later than the close of business on the tenth (10 th) day following the earlier of (i) the day on which such notice of the date of such meeting was mailed, or (ii) the day on which such public disclosure was made. To be in proper written form, each notice of proposal must set forth (i) for proposed nominees, the name, age and address of such person, principal occupation or employment, shares beneficially owned, and other information required to be disclosed by

205

|  | IBKC |  | First Horizon
|  | be included in the proxy statement for the meeting must notify IBKC in writing at least sixty days before the one year anniversary of the most recent annual meeting of the shareholder’s intention. The notice must contain: (a) a brief description of the proposal and the reasons for conducting such business at the annual meeting, (b) the name, address and stockholdings of the shareholder submitting the proposal and other shareholders supporting the proposal, and (c) any financial interest of the shareholder in the proposal. |  | federal securities laws, (ii) for other proposals, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of the shareholder, on whose behalf the proposal is made; and in each case (iii) as to the shareholder giving the notice (A) the name and address of the shareholder and any other shareholder known by such shareholder to be supporting the proposal; (B) the class and number of shares of First Horizon stock beneficially owned by such shareholder on the date of such shareholder’s notice and by any other shareholders known by such shareholder to be supporting such proposal. First Horizon may also require any proposed nominee to furnish such other information as it may reasonably request to determine the eligibility of the proposed nominee to serve as an independent director and to comply with applicable law.
Proxy Access |  | Same as above. |  | The First Horizon’s bylaws permit a shareholder, or a group of up to twenty (20) shareholders, who has maintained continuous ownership of three percent (3%) or more of the outstanding shares of First Horizon common stock for at least the previous three (3) years (as of the date the notice of nomination is delivered to First Horizon and through the meeting date) to nominate and include in First Horizon’s annual meeting proxy materials director nominees constituting up to the greater of two (2) individuals and twenty percent (20%) of the First Horizon board of directors as of the last day on which the notice of nomination may be submitted pursuant to First Horizon’s bylaws, provided that the shareholder(s) and the nominee(s) satisfy the requirements specified in First Horizon’s bylaws and First Horizon receives notice of such nominations as required under First Horizon’s bylaws.
|  |  |  | First Horizon’s bylaws provide that each shareholder seeking to include a

206

|  | IBKC |  | First Horizon
|  |  |  | director nominee in First Horizon’s proxy materials is required to provide First Horizon with certain information and undertakings specified in the First Horizon’s bylaws.
Anti-Takeover Provisions and Other Stockholder / Shareholder Protections |  | There is no business combination or control share statute under Louisiana law. The IBKC articles of incorporation and bylaws contain no special requirements for transactions with interested parties. |  | The Tennessee Business Combination Act generally prohibits a “business combination” by First Horizon or a subsidiary with an “interested shareholder” within five years after the shareholder becomes an interested shareholder. First Horizon or a subsidiary can, however, enter into a business combination within that period if, before the interested shareholder became such, the First Horizon board of directors approved the business combination or the transaction in which the interested shareholder became an interested shareholder. After that five-year moratorium, the business combination with the interested shareholder can be consummated only if it satisfies certain fair price criteria or is approved by two-thirds of the other shareholders. For purposes of the TBCA, a “business combination” includes mergers, share exchanges, sales and leases of assets, issuances of securities, and similar transactions. An “interested shareholder” is generally any person or entity that beneficially owns 10% or more of the voting power of any outstanding class or series of First Horizon’s stock.
|  |  |  | First Horizon’s charter does not have special requirements for transactions with interested parties; however, to the extent that the Tennessee Business Combination Act applies to First Horizon, all business combinations, as defined above, must be approved by two-thirds of the directors and a majority of the shares entitled to vote or a majority of the directors and two-thirds of the shares entitled to vote.
|  |  |  | The Tennessee Control Share Acquisition Act only applies if a Tennessee corporation’s charter or bylaws expressly provides that the

207

|  | IBKC |  | First Horizon
|  |  |  | corporation will be subject to such Act. First Horizon’s charter and bylaws do not provide that it will be governed under the Tennessee Control Share Acquisition Act.
Limitation of Personal Liability of Officers and Directors |  | IBKC’s articles of incorporation provide that a director or officer of IBKC will not be personally liable for monetary damages for any action taken, or any failure to take any action, as a director or officer except to the extent that by law a director’s or officer’s liability for monetary damages may not be limited. This provision does not eliminate or limit the liability of directors and officers for (i) actions taken in a grossly negligent manner, as defined in the Louisiana Banking Law, (ii) conduct that demonstrates a greater disregard of the duty of care than gross negligence, including intentional tortious conduct or intentional breach of the director’s or officer’s duty of loyalty, (iii) violations of Section 833 of the LBCA (relating to unlawful distributions), or (iv) an intentional violation of criminal law. |  | First Horizon’s charter provides that directors of First Horizon will not be personally liable to First Horizon or its shareholders for money damages, except for liability (i) for any breach of the director’s duty of loyalty to First Horizon or its shareholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, or (iii) under Section 48-18-302 of the TBCA (with respect to the unlawful payment of any dividends).
Indemnification of Directors and Officers and Insurance |  | IBKC’s articles of incorporation provide that IBKC shall indemnify, to the fullest extent permitted by law, any person who is or was a director or officer of IBKC or who was or is made a party to, or is threatened to be made a party to, any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including in actions or suits by or in the right of IBKC, by reason of such service or the fact that such person is or was serving as a director, officer, employee or agent of another corporation or organization at the request of IBKC) against costs, charges, expenses, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person. This indemnification is conditioned upon the director or officer having acted in good faith and in a manner he or she reasonably |  | First Horizon’s bylaws provide that if any current or former officer is wholly successful in the defense of any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative and whether formal or informal, and such officer is a party to such proceeding because he or she was an officer of First Horizon, the officer will be entitled to indemnification. If any current or former officer is not wholly successful, he or she may still be entitled to indemnification if the officer (i) acted in good faith, (ii) reasonably believed that the conduct was in First Horizon’s best interest, and (iii) the officer had no reason to think the conduct was unlawful. However, First Horizon will not indemnify any officer in any proceeding by or in the right of First Horizon in which the officer was adjudged liable to First Horizon

208

|  | IBKC |  | First Horizon
|  | believed to be in, or not opposed to, the best interest of IBKC and, with respect to any criminal action or proceeding, having no reasonable cause to believe that his or her conduct was unlawful. With respect to a director’s or officer’s actions in an official capacity, the LBCA further provides that indemnification may only be paid if the director or officer acted in a manner he or she reasonably believed to be in the best interest of IBKC. Under the LBCA, IBKC may not indemnify a director or officer in any proceeding with respect to conduct for which the director or officer was adjudged liable on the basis of receiving a financial benefit to which he or she was not entitled, whether or not involving action in the director’s or officer’s official capacity. Under the articles of incorporation, IBKC may advance litigation expenses to a director or officer, conditioned upon such person’s undertaking to repay such expenses if it is ultimately determined that he or she was not entitled to indemnification. In addition, the LBCA requires that an advance of litigation expenses to a director be conditioned on the prior receipt of a written affirmation of the director’s good faith belief that he or she has met the relevant standard of conduct or that the proceeding involves only duty of care claims from which he or she has been exculpated. |  | or in any other proceeding in which the officer is charged with receiving an improper benefit and adjudged liable or on the basis that personal benefit was improperly received by the officer. Such officer is entitled to an advancement of indemnifiable expenses provided that the officer agrees to repay the advance if it is ultimately determined that the officer is not entitled to indemnification and indemnification is not otherwise precluded. Employees and former directors are entitled to the same indemnification rights as any officer. First Horizon’s bylaws provide that First Horizon may purchase and maintain insurance on behalf of its directors, officers, employees and agents against any liability, whether or not First Horizon would have the power to indemnify such person against such liability under its charter. First Horizon maintains such insurance. First Horizon’s bylaws provide mandatory indemnification to each director and to officers designated by the board to the maximum extent permitted by law and authorize individual indemnity agreements. Each of First Horizon’s directors and certain of its officers have entered into indemnity agreements with First Horizon, forms of which are on file with the SEC.
|  | The rights of indemnification provided in IBKC’s articles of incorporation are not exclusive of any other rights that may be available under the bylaws, any insurance or other agreement, by vote of shareholders or directors, or otherwise. The articles of incorporation authorize IBKC to maintain insurance on behalf of any person who is or was a director, officer, employee or agent of IBKC, whether or not IBKC would have the power to provide indemnification to such person. IBKC maintains such |  |

209

|  | IBKC |  | First Horizon
|  | insurance consistent with the articles of incorporation. IBKC may also enter into agreements with its officers, directors, employees and agents for the purpose of securing or insuring in any manner its obligation to indemnify or advance expenses provided for in the provisions in the articles of incorporation regarding indemnification. IBKC has entered into indemnification agreements with two executive officers, forms of which are on file with the SEC. |  |
Dissenters’ Rights |  | Under the LBCA, a shareholder of a Louisiana corporation may receive payment of the fair value of his or her shares in the event of certain major corporate transactions, including a proposed merger or a sale of all or substantially all of the assets of the corporation for which shareholder approval is required. However, appraisal rights generally are not available to holders of a class of shares that is either: (a) a “covered security” under Section 18(b)(1)(A) or (B) of the Securities Act, or (b) traded in an organized market and has at least 2,000 shareholders and a market value of at least $20 million, exclusive of the value of such shares held by the corporation’s subsidiaries, senior executive officers, and directors and by beneficial shareholders and voting trust beneficial owners owning more than 10% of such shares. |  | The TBCA provides that a shareholder of a corporation may receive payment of the fair value of his or her stock if the shareholder dissents from certain major corporate transactions including a proposed merger, share exchange or a sale of substantially all of the assets of the corporation. However, dissenters’ rights generally are not available to holders of shares where the company (rather than a company subsidiary) is not one of the merging parties. Additionally, Section 48-23-102 of the TBCA provides that dissenters’ rights are generally not available to holders of shares of a security which, is listed on an exchange registered under Section 6 of the Exchange Act or is a “national market system security,” as defined in the rules promulgated pursuant to the Exchange Act.
Dividends |  | IBKC’s articles of incorporation provide that IBKC’s board of directors may declare a dividend out of funds lawfully available for such purpose, subject to the rights and preferences of any class of stock having preference over the common stock. Under the LBCA, IBKC may not declare a dividend if, after giving effect to such dividend, it would not be able to pay its debts as the debts become due in the usual course of business or if its total assets would be less than the sum of its total liabilities, plus the amount that would |  | First Horizon’s bylaws provide that the First Horizon board of directors may declare a dividend and direct payment of dividends or other distributions upon the outstanding shares out of funds legally available for such purposes as permitted by law. Under Tennessee law, First Horizon may not declare a dividend if, after giving effect to such dividend, it would not be able to pay its debts as the debts become due in its usual course of business or if its total assets would be less than the sum of its total liabilities, plus, unless the charter permits otherwise, the amount that

210

|  | IBKC |  | First Horizon
|  | be needed, if IBKC were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution. |  | would be needed, if First Horizon were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of shareholders whose preferential rights are superior to those receiving the distribution.
Amendments to Charter and Bylaws |  | The LBCA provides that, with the limited exception of certain non-substantive amendments that can be adopted by the board of directors without shareholder action, a Louisiana corporation’s board of directors may propose one or more amendments to the articles of incorporation for submission to the shareholders. Except as set forth in IBKC’s articles of incorporation, the proposed amendment is adopted if it receives the approval of at least a majority of the votes entitled to be cast on the amendment (including the approval of a majority of the votes entitled to be cast on the amendment by any separate voting group). IBKC’s articles of incorporation require the affirmative vote of the holders of at least 75% of the shares of IBKC entitled to vote generally in an election of directors, voting together as a single class, as well as such additional vote of the preferred stock as may be required by the provisions of any series thereof, to amend, adopt, alter, change or repeal any provisions inconsistent with provisions relating to the number, nomination, election and removal of directors; absence of preemptive rights; personal liability, indemnification, advancement of expenses and other rights of officers, directors, employees and agents; meetings of shareholders and shareholder proposals; and amendment of the articles and bylaws. IBKC’s bylaws may be amended or repealed or new bylaws adopted either by a majority of the directors then in office or by the affirmative vote of the holders of a majority of shares of IBKC entitled to vote generally in an election of directors, voting together as a single class, as well as such |  | Unless otherwise provided in the charter, the TBCA provides that with the limited exception of certain non-substantive amendments that can be adopted by the board of directors without shareholder action, a corporation’s board of directors may propose one or more amendments to the charter for submission to the shareholders. The proposed amendment (excluding First Horizon’s Article 12 relating to directors and the bylaws) is adopted if it receives the affirmative vote of a majority of the votes cast on the proposed amendment. Amendments to First Horizon’s Article 12 require an affirmative vote of at least 80% of the outstanding shares entitled to vote. First Horizon’s bylaws may be amended or repealed or new bylaws adopted either by a majority of the board of directors or by a vote of the holders of at least 80% of the outstanding shares of stock entitled to vote at any annual or special meeting if notice of the proposed amendment, repeal, or adoption is contained in the notice of the meeting.

211

|  | IBKC |  | First Horizon
|  | additional vote of the preferred stock as may be required by the provision of any series thereof. However, the affirmative vote of the holders of at least 75% of the shares of IBKC entitled to vote generally in an election of directors, voting together as a single class, as well as such additional vote of the preferred stock as may be required by the provisions of any series thereof, shall be required to amend, adopt, alter, change or repeal any provision inconsistent with bylaws relating to meetings of the IBKC board of directors or certification of stock. |  |
Action by Written Consent of the Stockholders / Shareholders |  | Under the LBCA and IBKC’s articles of incorporation, any action required or permitted to be taken by the shareholders at a meeting may be taken without a meeting if consent in writing setting forth the action so taken shall be signed by all of the shareholders who would be entitled to vote at a meeting for such purpose and filed with the Secretary of IBKC as part of the corporate records. |  | Under the TBCA, any action required or permitted to be taken at an annual or special meeting of holders of common stock may be taken without a meeting, without prior notice, and without a vote, if before or after the action all the shareholders entitled to vote consent in writing.
Stockholder / Shareholder Rights Plan |  | IBKC does not have a rights plan in effect. The IBKC board of directors has the authority to adopt certain forms of rights plans without action or approval by shareholders. |  | First Horizon does not have a rights plan in effect. The First Horizon board of directors has the authority to adopt certain forms of rights plans without action or approval by shareholders.
Forum Selection Bylaw |  | IBKC’s bylaws do not require any exclusive forum with respect to legal actions against or involving IBKC. |  | First Horizon’s bylaws provide that the exclusive forum for four specified categories of legal actions against or involving First Horizon, including derivative actions, actions claiming breach of fiduciary duty, actions involving corporation law or First Horizon’s charter or bylaws, and actions involving the internal affairs legal doctrine, will be a state or federal court located within Shelby County in the State of Tennessee. To the fullest extent permitted by law, this provision will apply to any actions or proceedings described in the prior sentence that arise or purport to arise under the federal securities laws, including the Securities Act and Exchange Act. To the extent these

212

|  | IBKC |  | First Horizon
|  |  |  | exclusive forum provisions restrict the courts in which holders of First Horizon common stock may bring claims arising under the federal securities laws, there is uncertainty as to whether a court would enforce such provisions.

As set forth in the First Horizon bylaws, a shareholder or group of up to twenty (20) shareholders that has held at least three percent (3%) of First Horizon’s common stock for at least three (3) years is able to submit director nominees for up to twenty percent (20%) of the First Horizon board of directors (but at least two directors) for inclusion in the First Horizon proxy statement if the shareowner(s) and nominee(s) satisfy the requirements specified in the First Horizon bylaws and notice is received between one hundred and fifty (150) and one hundred and twenty (120) calendar days before the anniversary of the date that First Horizon mailed its proxy statement for the prior year’s annual meeting of shareholders. In order for a nominee to be considered for inclusion in First Horizon’s proxy statement for the First Horizon 2020 annual meeting, a shareholder must deliver timely notice in writing to the First Horizon Corporate Secretary (at the address above) no earlier than October 12, 2019 and no later than November 11, 2019. The notice must contain the specific information required by Section 3.16 of the First Horizon bylaws. If the First Horizon 2020 annual meeting is not scheduled to be held within thirty (30) days before or thirty (30) days after the first anniversary date of the previous year’s annual meeting, the nomination must be submitted by the later of the close of business on the date that is on hundred and eighty (180) days prior to the First Horizon 2020 annual meeting date or the tenth day following the date such annual meeting date is first publicly announced or disclosed.

Other Proposals and Nominations. Sections 2.8 and 3.6 of the First Horizon bylaws provide that a shareholder who wishes to bring before a shareholder meeting a director nomination or other proposal, outside the processes that permit them to be included in First Horizon’s proxy statement, must comply with certain procedures. These procedures require written notification to First Horizon, generally not less than ninety (90) nor more than one hundred and twenty (120) days prior to the date of the shareholder meeting. Such shareholder proposals and nominations must be submitted to the Corporate Secretary. Section 2.4 of First Horizon’s bylaws provides that the annual meeting of shareholders will be held each year on the date and at the time fixed by the First Horizon board of directors. The board of directors has determined that the First Horizon 2020 annual meeting will be held on April 28, 2020. Thus, shareholder proposals and director nominations submitted outside the processes that permit them to be included in First Horizon’s proxy statement must be submitted to the Corporate Secretary between December 30, 2019 and January 29, 2020, or the proposals will be considered untimely. If First Horizon gives fewer than one hundred (100) days’ notice or public disclosure of a shareholder meeting date to shareholders, then it must receive the shareholder notification not later than ten (10) days after the earlier of the date notice of the shareholders’ meeting was mailed or publicly disclosed. Untimely proposals may be excluded by the Chairman of the First Horizon board of directors or First Horizon’s proxies may exercise their discretion and vote on these matters in a manner they determine to be appropriate.

RECITALS

A. The Boards of Directors of First Horizon and IBKC have determined that it is in the best interests of their respective companies and their shareholders to consummate the strategic business combination transaction provided for in this Agreement, pursuant to which IBKC will, subject to the terms and conditions set forth herein, merge with and into First Horizon (the “Merger”), so that First Horizon is the surviving entity (in such capacity, the “Surviving Entity”) in the Merger.

B. In furtherance thereof, the respective Boards of Directors of First Horizon and IBKC have approved the Merger and adopted this Agreement and have resolved to submit this Agreement to their respective shareholders for approval and to recommend that their respective shareholders approve this Agreement.

C. For federal income tax purposes, it is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), and this Agreement is intended to be and is adopted as a plan of reorganization for purposes of Sections 354 and 361 of the Code.

D. In this Agreement, the parties desire to make certain representations, warranties and agreements in connection with the Merger and also to prescribe certain conditions to the Merger.

NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties and agreements contained in this Agreement, and intending to be legally bound, the parties agree as follows:

ARTICLE I

T HE M ERGER

1.1 The Merger. Subject to the terms and conditions of this Agreement, in accordance with the Tennessee Business Corporation Act (the “TBCA”) and the Louisiana Business Corporation Act (the “LBCA”), at the Effective Time, IBKC shall merge with and into First Horizon pursuant to this Agreement. First Horizon shall be the Surviving Entity, and shall continue its corporate existence under the laws of the State of Tennessee. Upon consummation of the Merger, the separate corporate existence of IBKC shall terminate.

1.2 Closing. Subject to the terms and conditions of this Agreement, the closing of the Merger (the “Closing”) will take place by electronic exchange of documents at 10:00 a.m., New York City time, on a date which shall be no later than three (3) business days after the satisfaction or waiver (subject to applicable law) of all of the conditions set forth in Article VII hereof (other than those conditions that by their nature can only be satisfied at the Closing, but subject to the satisfaction or waiver thereof), unless another date, time or place is agreed to in writing by IBKC and First Horizon. The date on which the Closing occurs is referred to as the “Closing Date.”

1.3 Effective Time. On or (if agreed by IBKC and First Horizon) prior to the Closing Date, First Horizon and IBKC, respectively, shall cause to be filed articles of merger with the Secretary of State of the State of Tennessee (the “Tennessee Secretary”) and articles of merger with the Secretary of State of the State of Louisiana (the “Louisiana Secretary”) (collectively, the “Articles of Merger”). The Merger shall become effective at such time as specified in the Articles of Merger in accordance with the relevant provisions of the TBCA and LBCA, or at such other time as shall be provided by applicable law (such time hereinafter referred to as the “Effective Time”).

A-8

1.4 Effects of the Merger. At and after the Effective Time, the Merger shall have the effects set forth in the applicable provisions of the TBCA, the LBCA and this Agreement.

1.5 Conversion of IBKC Common Stock. At the Effective Time, by virtue of the Merger and without any action on the part of First Horizon, IBKC or the holder of any securities of First Horizon or IBKC:

(a) Subject to Section 2.2(e), each share of the common stock, par value $1.00 per share, of IBKC issued and outstanding immediately prior to the Effective Time (the “IBKC Common Stock”), except for shares of IBKC Common Stock owned by IBKC or First Horizon (in each case, other than shares of IBKC Common Stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties, or (ii) held, directly or indirectly, by IBKC or First Horizon in respect of debts previously contracted), shall be converted into the right to receive 4.584 shares (the “Exchange Ratio”; and such shares, the “Merger Consideration”) of the common stock, par value $0.625, of First Horizon (the “First Horizon Common Stock”); it being understood that at and after the Effective Time, pursuant to Section 1.6, the First Horizon Common Stock, including the shares issued to former holders of IBKC Common Stock, shall be the common stock of the Surviving Entity.

(b) All of the shares of IBKC Common Stock converted into the right to receive the Merger Consideration pursuant to this Article I shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time, and each certificate (each, an “Old Certificate”; it being understood that any reference herein to “Old Certificate” shall be deemed to include reference to book-entry account statements relating to the ownership of shares of IBKC Common Stock) previously representing any such shares of IBKC Common Stock shall thereafter represent only the right to receive (i) a New Certificate representing the number of whole shares of First Horizon Common Stock that such shares of IBKC Common Stock have been converted into the right to receive, (ii) cash in lieu of fractional shares which the shares of IBKC Common Stock represented by such Old Certificate have been converted into the right to receive pursuant to this Section 1.5 and Section 2.2(e), without any interest thereon, and (iii) any dividends or distributions that the holder thereof has the right to receive pursuant to Section 2.2, in each case, without any interest thereon. If, prior to the Effective Time, the outstanding shares of First Horizon Common Stock or IBKC Common Stock shall have been increased, decreased, changed into or exchanged for a different number or kind of shares or securities as a result of a reorganization, recapitalization, reclassification, stock dividend, stock split, reverse stock split or other similar change in capitalization, or there shall be any extraordinary dividend or distribution, an appropriate and proportionate adjustment shall be made to the Exchange Ratio to give First Horizon and the holders of IBKC Common Stock the same economic effect as contemplated by this Agreement prior to such event; provided, that nothing contained in this sentence shall be construed to permit IBKC or First Horizon to take any action with respect to its securities or otherwise that is prohibited by the terms of this Agreement.

(c) Notwithstanding anything in this Agreement to the contrary, at the Effective Time, all shares of IBKC Common Stock that are owned by IBKC or First Horizon (in each case, other than shares of IBKC Common Stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties, or (ii) held, directly or indirectly, by IBKC or First Horizon in respect of debts previously contracted) shall be cancelled and shall cease to exist and no First Horizon Common Stock or other consideration shall be delivered in exchange therefor.

1.6 First Horizon Stock. At and after the Effective Time, each share of First Horizon Common Stock and each share of First Horizon Preferred Stock issued and outstanding immediately prior to the Effective Time shall remain an issued and outstanding share of common stock or preferred stock, as applicable, of the Surviving Entity and shall not be affected by the Merger.

1.7 IBKC Preferred Stock. At the Effective Time, by virtue of the Merger and without any action on the part of First Horizon, IBKC or the holder of any securities of First Horizon or IBKC:

A-9

(a) Each share of 6.625% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series B, par value $1.00 per share, of IBKC (“IBKC Series B Preferred Stock”) issued and outstanding immediately prior to the Effective Time, other than Dissenting Shares, shall be converted into the right to receive a share of a newly created series of preferred stock of First Horizon having the same terms (taking into account that IBKC will not be the surviving entity in the Merger and, if the Closing Date is after August 1, 2020, with the Optional Redemption (as defined in Article 4, Section D of the IBKC Articles), beginning on a date that is five years after the Closing Date) as the IBKC Series B Preferred Stock (all shares of such newly created series, collectively, the “First Horizon Series B Preferred Stock”) and, upon such conversion, the IBKC Series B Preferred Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time.

(b) Each share of 6.60% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series C, par value $1.00 per share, of IBKC (“IBKC Series C Preferred Stock”) issued and outstanding immediately prior to the Effective Time, other than Dissenting Shares, shall be converted into the right to receive a share of a newly created series of preferred stock of First Horizon having the same terms (taking into account that IBKC will not be the surviving entity in the Merger) as the IBKC Series C Preferred Stock (all shares of such newly created series, collectively, the “First Horizon Series C Preferred Stock”) and, upon such conversion, the IBKC Series C Preferred Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time.

(c) Each share of 6.100% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series D, par value $1.00 per share, of IBKC (“IBKC Series D Preferred Stock,” and together with the IBKC Series B Preferred Stock and IBKC Series C Preferred Stock, the “IBKC Preferred Stock”) issued and outstanding immediately prior to the Effective Time, other than Dissenting Shares, shall be converted into the right to receive a share of a newly created series of preferred stock of First Horizon having identical powers, preferences and special rights as the IBKC Series D Preferred Stock (all shares of such newly created series, collectively, the “First Horizon Series D Preferred Stock,” and collectively with the First Horizon Series B Preferred Stock and First Horizon Series C Preferred Stock, the “New First Horizon Preferred Stock”) and, upon such conversion, the IBKC Series D Preferred Stock shall no longer be outstanding and shall automatically be cancelled and shall cease to exist as of the Effective Time.

(d) Notwithstanding anything in this Section 1.7 to the contrary, all shares of IBKC Preferred Stock that are issued and outstanding immediately prior to the Effective Time and are held by a holder of IBKC Preferred Stock who exercises appraisal rights in respect of such shares when and in the manner required under Part 13 of the LBCA (“Dissenting Shares”), shall not be converted as provided in Sections 1.7(a), 1.7(b) or 1.7(c), as applicable, but instead, such holder shall be entitled only to such rights as are granted with respect to the payment of the fair value of such shares under the applicable provisions of Part 13 of the LBCA (and at the Effective Time, such Dissenting Shares shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and such holder shall cease to have any rights with respect thereto, except the rights provided for pursuant to the applicable provisions of Part 13 of the LBCA and this Section 1.7(d)), unless and until such holder shall have failed to perfect or effectively withdrawn or lost rights to demand or receive the fair value of such shares under the LBCA. If, after the Effective Time, any holder of Dissenting Shares fails to perfect or effectively withdraws or loses the right to dissent, the applicable Dissenting Shares will thereupon be treated as though such shares had been converted into shares of New First Horizon Preferred Stock pursuant to this Section 1.7. If any holder of shares of IBKC Preferred Stock provides notice to IBKC of such holder’s intent to demand or receive fair value of such shares under the LBCA, IBKC will promptly give First Horizon notice thereof (and of any other instruments served pursuant to Part 13 of the LBCA), and First Horizon will have the right to participate in all negotiations and proceedings with respect to any such demands. IBKC will not, except with the prior written consent of First Horizon, voluntarily make any payment with respect to, or settle or offer to settle, any such demand.

1.8 Treatment of IBKC Equity Awards.

(a) At the Effective Time, any vesting conditions applicable to each option to purchase shares of IBKC Common Stock (an “IBKC Stock Option”) that is outstanding and unexercised immediately prior to the Effective Time shall be deemed satisfied and accelerate in full and each IBKC Stock Option shall, automatically and without any required action on the part of the holder thereof, be converted into an option (a “First Horizon Stock Option”) to purchase (i) that number of shares of First Horizon Common Stock (rounded down to the nearest whole share) equal to the product of (A) the total number of shares of IBKC Common Stock subject to such IBKC Stock Option immediately prior to the Effective Time multiplied by (B) the Exchange Ratio (as adjusted if necessary pursuant to the last sentence of Section 1.5(b)), (ii) at an exercise price per share of First Horizon Common Stock (rounded up to the nearest whole cent) equal to the quotient of (A) the exercise price per share of IBKC Common Stock of such IBKC Stock Option immediately prior to the Effective Time divided by (B) the Exchange Ratio (as adjusted if necessary pursuant to the last sentence of Section 1.5(b)); provided, however, that the exercise price and the number of shares of First Horizon Common Stock purchasable pursuant to the IBKC Stock Options shall be determined in a manner consistent with the requirements of Section 409A of the Internal Revenue Code; provided, further, that in the case of any IBKC Stock Option to which Section 422 of the Internal Revenue Code applies, the exercise price and the number of shares of First Horizon Common Stock purchasable pursuant to such option shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Internal Revenue Code. Except as expressly provided in this Section 1.8(a), each such First Horizon Stock Option shall be subject to the same terms and conditions (including exercisability and forfeiture terms), after giving effect to any “change in control” provisions under the applicable IBKC equity incentive plan or award agreement, as applied to the corresponding IBKC Stock Option immediately prior to the Effective Time.

(b) At the Effective Time, any vesting conditions applicable to each award in respect of a share of IBKC Common Stock subject to vesting, repurchase or other lapse restriction (an “IBKC Restricted Stock Award”) that is outstanding immediately prior to the Effective Time shall be deemed satisfied and accelerate in full and each IBKC Restricted Stock Award shall, automatically and without any required action on the part of the holder thereof, be cancelled and shall only entitle the holder to receive immediately following the Effective Time, the Merger Consideration (less applicable Taxes required to be withheld with respect to such vesting).

(c) At the Effective Time, (i) any vesting conditions applicable to each performance stock unit award in respect of shares of IBKC Common Stock (an “IBKC PSU Award”) that is outstanding immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder thereof, accelerate in full, and (ii) each IBKC PSU Award shall, automatically and without any required action on the part of the holder thereof, be cancelled and shall only entitle the holder to receive (without interest), immediately following the Effective Time, an amount of Merger Consideration (less applicable Taxes required to be withheld with respect to such vesting) equal to (x) the number of shares of IBKC Common Stock subject to such IBKC PSU Award immediately prior to the Effective Time (including any applicable dividend equivalents) based on the greater of (A) the target performance level, or (B) the actual performance level through September 30, 2019 as reasonably determined by the compensation committee of the IBKC Board of Directors (the “IBKC Compensation Committee”), multiplied by (y) the Exchange Ratio (as adjusted if necessary pursuant to the last sentence of Section 1.5(b)); provided, that, with respect to any IBKC PSU Award that constitutes nonqualified deferred compensation subject to Section 409A of the Code and that is not permitted to be paid at the Effective Time without triggering a Tax or penalty under Section 409A of the Code, such payment shall be made at the earliest time permitted under the applicable IBKC equity incentive plan and award agreement that will not trigger a Tax or penalty under Section 409A of the Code.

(d) At the Effective Time, each phantom stock award in respect of shares of IBKC Common Stock (an “IBKC Phantom Stock Award”) that is outstanding and unvested immediately prior to the Effective Time shall, automatically and without any required action on the part of the holder

A-11

thereof, vest and be cancelled and automatically entitle the holder of such IBKC Phantom Stock Award to receive (without interest), on the first regularly scheduled payroll date of First Horizon following the Closing Date, an amount in cash (rounded to the nearest cent and less applicable Taxes required to be withheld with respect to such vesting) determined by multiplying (i) the closing price of one share of First Horizon Common Stock on the Closing Date by (ii) the number of shares of First Horizon Common Stock underlying such IBKC Phantom Stock Award (as determined by multiplying (x) the number of shares of IBKC Common Stock (including any applicable dividend equivalents) underlying such IBKC Phantom Stock Award by (y) the Exchange Ratio) (the “Phantom Stock Consideration”); provided, that, to the extent a holder of IBKC Phantom Stock Awards has made a deferral election in respect of payments pursuant to such IBKC Phantom Stock Awards, the applicable portion of the Phantom Stock Consideration shall be credited to such holder’s deferred compensation account under IBKC’s Executive Nonqualified Excess Plan.

(e) At or prior to the Effective Time, IBKC, the Board of Directors of IBKC and the IBKC Compensation Committee, as applicable, shall adopt any resolutions and take any actions that are necessary or appropriate to effectuate the provisions of this Section 1.8 and provide for the deduction, withholding and remittance of any Taxes or amounts required under applicable law.

(f) As of the Effective Time, the number and kind of shares available for issuance under each IBKC equity or equity-based incentive plan shall be adjusted to reflect First Horizon Common Stock in accordance with the provisions of the applicable plan.

(g) First Horizon shall take all corporate actions that are necessary for the treatment of the IBKC Equity Awards pursuant to Section 1.8(a) through 1.8(d) and Section 1.8(h), including the reservation, issuance and listing of First Horizon Common Stock as necessary to effect the transactions contemplated by this Section 1.8. As soon as practicable following the Effective Time, First Horizon shall file with the SEC a post-effective amendment to the Form S-4 or a registration statement on Form S-8 (or any successor or other appropriate form) with respect to the shares of First Horizon Common Stock underlying such IBKC Equity Awards (other than the IBKC Phantom Stock Awards), and shall use reasonable best efforts to maintain the effectiveness of such registration statement for so long as the relevant IBKC equity incentive plans remain in effect and such registration of shares of First Horizon Common Stock issuable thereunder continues to be required.

(h) Notwithstanding anything in Section 1.8(a) through Section 1.8(e) to the contrary, but subject to Section 5.2(b), (i) to the extent the terms of any IBKC Equity Award granted on or after the date of this Agreement and not in violation of this Agreement expressly provides for treatment in connection with the occurrence of the Effective Time that is different from the treatment prescribed by this Section 1.8, or (ii) as mutually agreed by the parties and a holder of any IBKC Equity Award, then in each case, the terms of such IBKC Equity Award or mutual agreement, as applicable, shall control (and the applicable provisions of this Section 1.8 shall not apply); provided, that such IBKC Equity Award shall automatically and without any required action on the part of the holder thereof, cease to represent an equity award denominated in shares of IBKC Common Stock and shall be converted into an equity award denominated in shares of First Horizon Common Stock (a “Converted Equity Award”). The number of shares of First Horizon Common Stock subject to each such Converted Equity Award shall equal the product (with the result rounded down to the nearest whole number) of (i) the number of shares of IBKC Common Stock subject to such IBKC Equity Award immediately prior to the Effective Time multiplied by (ii) the Exchange Ratio (as adjusted if necessary pursuant to the last sentence of Section 1.5(b)); provided, that to the extent any Converted Equity Award is an IBKC Stock Option (a “Converted Stock Option”), the exercise price per share of such Converted Stock Option shall be equal to the quotient (rounded up to the nearest whole cent) of (A) the exercise price per share of IBKC Common Stock of such IBKC Stock Option immediately prior to the Effective Time divided by (B) the Exchange Ratio (as adjusted if necessary pursuant to the last sentence of Section 1.5(b)); and provided, however, that the exercise price and the number of shares of First Horizon Common Stock purchasable pursuant to the Converted Stock Options shall be determined in a manner consistent with the requirements of Section 409A of the Internal Revenue Code; provided, further, that in the case of any IBKC Stock

A-12

Option to which Section 422 of the Internal Revenue Code applies, the exercise price and the number of shares of First Horizon Common Stock purchasable pursuant to such option shall be determined in accordance with the foregoing, subject to such adjustments as are necessary in order to satisfy the requirements of Section 424(a) of the Internal Revenue Code.

1.9 Charter of Surviving Entity. At the Effective Time, the charter of First Horizon, as in effect immediately prior to the Effective Time, as amended pursuant to Section 6.20 and for the filing of the terms of the New First Horizon Preferred Stock, shall be the charter of the Surviving Entity until thereafter amended in accordance with applicable law.

1.10 Bylaws of Surviving Entity. At the Effective Time, the bylaws of First Horizon, as in effect immediately prior to the Effective Time, as amended as set forth in Exhibit A (such amendment, the “First Horizon Bylaw Amendment”), shall be the bylaws of the Surviving Entity until thereafter amended in accordance with applicable law.

1.11 Tax Consequences. It is intended that the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Code, and that this Agreement is intended to be and is adopted as a plan of reorganization for the purposes of Sections 354 and 361 of the Code.

1.12 Bank Merger. At the Bank Merger Effective Time (as defined below) IBERIABANK, a Louisiana-chartered bank and Subsidiary of IBKC (“IBERIABANK”), will merge with and into First Horizon Bank, a Tennessee-chartered bank and Subsidiary of First Horizon (“First Horizon Bank”) (the “Bank Merger”). First Horizon Bank shall be the surviving entity in the Bank Merger and, following the Bank Merger, the separate corporate existence of IBERIABANK shall cease. The Bank Merger shall be implemented pursuant to an agreement and plan of merger in form and substance agreed by First Horizon and IBKC, which shall be customary for mergers similar to the Bank Merger (the “Bank Merger Agreement”), which shall be entered into by First Horizon Bank and IBERIABANK promptly after the date of this Agreement. Each of First Horizon and IBKC shall approve the Bank Merger Agreement and the Bank Merger as the sole voting shareholder of First Horizon Bank and IBERIABANK, respectively, and First Horizon and IBKC shall, and shall cause First Horizon Bank and IBERIABANK, respectively, to, execute certificates or articles of merger and such other agreements, documents and certificates as are necessary to make the Bank Merger effective (“Bank Merger Certificates”) at the Bank Merger Effective Time. The Bank Merger shall become effective promptly following the Effective Time or at such later time and date as specified in the Bank Merger Agreement in accordance with applicable law (the “Bank Merger Effective Time”).

ARTICLE II

E XCHANGE OF S HARES

2.1 First Horizon to Make Consideration Available. At or prior to the Effective Time, First Horizon shall deposit, or shall cause to be deposited, with a bank or trust company mutually agreed upon by First Horizon and IBKC (the “Exchange Agent”), for exchange in accordance with this Article II for the benefit of the holders of Old Certificates (which for purposes of this Article II shall be deemed to include certificates or book-entry account statements representing shares of IBKC Preferred Stock), certificates or, at First Horizon’s option, evidence in book-entry form, representing shares of First Horizon Common Stock or New First Horizon Preferred Stock to be issued pursuant to Section 1.5 and Section 1.7, respectively (collectively, referred to herein as “New Certificates”), and cash in lieu of any fractional shares to be paid pursuant to Section 2.2(e) (such cash and New Certificates, together with any dividends or distributions with respect to shares of First Horizon Common Stock or New First Horizon Preferred Stock payable in accordance with Section 2.2(b), being hereinafter referred to as the “Exchange Fund”).

2.2 Exchange of Shares.

(a) As promptly as practicable after the Effective Time, but in no event later than five (5) business days thereafter, First Horizon shall cause the Exchange Agent to mail to each holder of record of

A-13

one or more Old Certificates representing shares of IBKC Common Stock or IBKC Preferred Stock immediately prior to the Effective Time that have been converted at the Effective Time into the right to receive First Horizon Common Stock or New First Horizon Preferred Stock, as applicable, pursuant to Article I, a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Old Certificates shall pass, only upon proper delivery of the Old Certificates to the Exchange Agent) and instructions for use in effecting the surrender of the Old Certificates in exchange for New Certificates representing the number of whole shares of First Horizon Common Stock and any cash in lieu of fractional shares or shares of New First Horizon Preferred Stock, as applicable, which the shares of IBKC Common Stock or IBKC Preferred Stock represented by such Old Certificate or Old Certificates shall have been converted into the right to receive pursuant to this Agreement as well as any dividends or distributions to be paid pursuant to Section 2.2(b). Upon proper surrender of an Old Certificate or Old Certificates for exchange and cancellation to the Exchange Agent, together with such properly completed letter of transmittal, duly executed, the holder of such Old Certificate or Old Certificates shall be entitled to receive in exchange therefor, as applicable, (i) (A) a New Certificate representing that number of whole shares of First Horizon Common Stock to which such holder of IBKC Common Stock shall have become entitled pursuant to the provisions of Article I, and (B) a check representing the amount of (x) any cash in lieu of fractional shares which such holder has the right to receive in respect of the Old Certificate or Old Certificates surrendered pursuant to the provisions of this Article II, and (y) any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), or (ii) (A) a New Certificate representing that number of shares of New First Horizon Preferred Stock to which such holder of IBKC Preferred Stock shall have become entitled pursuant to the provisions of Article I, and (B) a check representing the amount of any dividends or distributions which the holder thereof has the right to receive pursuant to Section 2.2(b), and the Old Certificate or Old Certificates so surrendered shall forthwith be cancelled. No interest will be paid or accrued on any cash in lieu of fractional shares or dividends or distributions payable to holders of Old Certificates. Until surrendered as contemplated by this Section 2.2, each Old Certificate shall be deemed at any time after the Effective Time to represent only the right to receive, upon surrender, the number of whole shares of First Horizon Common Stock or shares of New First Horizon Preferred Stock which the shares of IBKC Common Stock or IBKC Preferred Stock, as applicable, represented by such Old Certificate have been converted into the right to receive and any cash in lieu of fractional shares or in respect of dividends or distributions as contemplated by this Section 2.2.

(b) No dividends or other distributions declared with respect to First Horizon Common Stock or New First Horizon Preferred Stock shall be paid to the holder of any unsurrendered Old Certificate until the holder thereof shall surrender such Old Certificate in accordance with this Article II. After the surrender of an Old Certificate in accordance with this Article II, the record holder thereof shall be entitled to receive any such dividends or other distributions, without any interest thereon, which theretofore had become payable with respect to the whole shares of First Horizon Common Stock or shares of New First Horizon Preferred Stock that the shares of IBKC Common Stock or IBKC Preferred Stock, as applicable, represented by such Old Certificate have been converted into the right to receive.

(c) If any New Certificate representing shares of First Horizon Common Stock or New First Horizon Preferred Stock is to be issued in a name other than that in which the Old Certificate or Old Certificates surrendered in exchange therefor is or are registered, it shall be a condition of the issuance thereof that the Old Certificate or Old Certificates so surrendered shall be properly endorsed (or accompanied by an appropriate instrument of transfer) and otherwise in proper form for transfer, and that the person requesting such exchange shall pay to the Exchange Agent in advance any transfer or other similar Taxes required by reason of the issuance of a New Certificate representing shares of First Horizon Common Stock or New First Horizon Preferred Stock in any name other than that of the registered holder of the Old Certificate or Old Certificates surrendered, or required for any other reason, or shall establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

A-14

(d) After the Effective Time, there shall be no transfers on the stock transfer books of IBKC of the shares of IBKC Common Stock or IBKC Preferred Stock that were issued and outstanding immediately prior to the Effective Time. If, after the Effective Time, Old Certificates representing such shares are presented for transfer to the Exchange Agent, they shall be cancelled and exchanged for New Certificates representing shares of First Horizon Common Stock or New First Horizon Preferred Stock, cash in lieu of fractional shares and dividends or distributions as contemplated by this Section 2.2, as applicable.

(e) Notwithstanding anything to the contrary contained in this Agreement, no New Certificates or scrip representing fractional shares of First Horizon Common Stock shall be issued upon the surrender for exchange of Old Certificates, no dividend or distribution with respect to First Horizon Common Stock shall be payable on or with respect to any fractional share, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a shareholder of First Horizon. In lieu of the issuance of any such fractional share, First Horizon shall pay to each former holder of IBKC Common Stock who otherwise would be entitled to receive such fractional share an amount in cash (rounded to the nearest cent) determined by multiplying (i) the average of the closing-sale prices of First Horizon Common Stock on the New York Stock Exchange (the “NYSE”) as reported by The Wall Street Journal for the consecutive period of five (5) full trading days ending on the day preceding the Closing Date by (ii) the fraction of a share (after taking into account all shares of IBKC Common Stock held by such holder immediately prior to the Effective Time and rounded to the nearest one-thousandth when expressed in decimal form) of First Horizon Common Stock which such holder would otherwise be entitled to receive pursuant to Section 1.5. The parties acknowledge that payment of such cash consideration in lieu of issuing fractional shares is not separately bargained-for consideration, but merely represents a mechanical rounding off for purposes of avoiding the expense and inconvenience that would otherwise be caused by the issuance of fractional shares.

(f) Any portion of the Exchange Fund that remains unclaimed by the shareholders of IBKC for twelve (12) months after the Effective Time shall be paid to the Surviving Entity. Any former holders of IBKC Common Stock or IBKC Preferred Stock who have not theretofore complied with this Article II shall thereafter look only to the Surviving Entity for payment of the shares of First Horizon Common Stock, cash in lieu of any fractional shares and any unpaid dividends and distributions on the First Horizon Common Stock deliverable in respect of each former share of IBKC Common Stock such holder holds as determined pursuant to this Agreement, or the shares of New First Horizon Preferred Stock and any unpaid dividends and distributions on the New First Horizon Preferred Stock deliverable in respect of each former share of IBKC Preferred Stock such holder holds as determined pursuant to this Agreement, in each case, without any interest thereon. Notwithstanding the foregoing, none of First Horizon, IBKC, the Surviving Entity, the Exchange Agent or any other person shall be liable to any former holder of shares of IBKC Common Stock or IBKC Preferred Stock for any amount delivered in good faith to a public official pursuant to applicable abandoned property, escheat or similar laws.

(g) First Horizon shall be entitled to deduct and withhold, or cause the Exchange Agent to deduct and withhold, from any cash in lieu of fractional shares of First Horizon Common Stock, cash dividends or distributions payable pursuant to this Section 2.2 or any other amounts otherwise payable pursuant to this Agreement to any holder of IBKC Common Stock, IBKC Preferred Stock or IBKC Equity Awards, such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code or any provision of state, local or foreign Tax law. To the extent that amounts are so withheld by First Horizon or the Exchange Agent, as the case may be, and paid over to the appropriate Governmental Entity, the withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of IBKC Common Stock, IBKC Preferred Stock or IBKC Equity Awards in respect of which the deduction and withholding was made by First Horizon or the Exchange Agent, as the case may be.

(h) In the event any Old Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Old Certificate to be lost, stolen or destroyed and, if required by First Horizon or the Exchange Agent, the posting by such person of a bond in

A-15

such amount as First Horizon or the Exchange Agent may determine is reasonably necessary as indemnity against any claim that may be made against it with respect to such Old Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Old Certificate the shares of First Horizon Common Stock and any cash in lieu of fractional shares, or the shares of New First Horizon Preferred Stock, as applicable, and dividends or distributions, deliverable in respect thereof pursuant to this Agreement.

Except (a) as disclosed in the disclosure schedule delivered by IBKC to First Horizon concurrently herewith (the “IBKC Disclosure Schedule”) (it being understood that (i) no item is required to be set forth as an exception to a representation or warranty if its absence would not result in the related representation or warranty being deemed untrue or incorrect, (ii) the mere inclusion of an item in the IBKC Disclosure Schedule as an exception to a representation or warranty shall not be deemed an admission by IBKC that such item represents a material exception or fact, event or circumstance or that such item would reasonably be expected to have a Material Adverse Effect, and (iii) any disclosures made with respect to a section of this Article III shall be deemed to qualify (1) any other section of this Article III specifically referenced or cross-referenced, and (2) other sections of this Article III to the extent it is reasonably apparent on its face (notwithstanding the absence of a specific cross reference) from a reading of the disclosure that such disclosure applies to such other sections), or (b) as disclosed in any IBKC Reports filed with or furnished to the SEC by IBKC since December 31, 2016 and prior to the date hereof (but disregarding risk factor disclosures contained under the heading “Risk Factors,” or disclosures of risks set forth in any “forward-looking statements” disclaimer or any other statements that are similarly non-specific or cautionary, predictive or forward-looking in nature), IBKC hereby represents and warrants to First Horizon as follows:

3.1 Corporate Organization.

(a) IBKC is a corporation duly organized, validly existing and in good standing under the laws of the State of Louisiana, is a bank holding company duly registered under the Bank Holding Company Act of 1956, as amended (the “BHC Act”) and has elected to be treated as a financial holding company under the BHC Act. IBKC has the corporate power and authority to own, lease or operate all of its properties and assets and to carry on its business as it is now being conducted in all material respects. IBKC is duly licensed or qualified to do business and in good standing in each jurisdiction in which the nature of the business conducted by it or the character or location of the properties and assets owned, leased or operated by it makes such licensing, qualification or standing necessary, except where the failure to be so licensed or qualified or to be in good standing would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on IBKC. As used in this Agreement, the term “Material Adverse Effect” means, with respect to First Horizon, IBKC or the Surviving Entity, as the case may be, any effect, change, event, circumstance, condition, occurrence or development that, either individually or in the aggregate, has had or would reasonably be expected to have a material adverse effect on (i) the business, properties, assets, liabilities, results of operations or financial condition of such party and its Subsidiaries taken as a whole (provided, however, that, with respect to this clause (i), Material Adverse Effect shall not be deemed to include the impact of (A) changes, after the date hereof, in U.S. generally accepted accounting principles (“GAAP”) or applicable regulatory accounting requirements, (B) changes, after the date hereof, in laws, rules or regulations of general applicability to companies in the industries in which such party and its Subsidiaries operate, or interpretations thereof by courts or Governmental Entities (as defined below), (C) changes, after the date hereof, in global, national or regional political conditions (including the outbreak of war or acts of terrorism) or in economic or market (including equity, credit and debt markets, as well as changes in interest rates) conditions affecting the financial services industry generally and not specifically relating to such party or its Subsidiaries, (D) public disclosure of the execution of this Agreement, public

A-16

As used in this Agreement, the word “Subsidiary” when used with respect to any person, means any corporation, partnership, limited liability company, bank or other organization, whether incorporated or unincorporated, or person of which (x) such first person directly or indirectly owns or controls at least a majority of the securities or other interests having by their terms ordinary voting power to elect a majority of the board of directors or others performing similar functions, or (y) such first person is or directly or indirectly has the power to appoint a general partner, manager or managing member or others performing similar functions. True and complete copies of the articles of incorporation of IBKC (the “IBKC Articles”) and the bylaws of IBKC (the “IBKC Bylaws”), in each case, as in effect as of the date of this Agreement, have previously been made available by IBKC to First Horizon.

(b) Except as would not, either individually or in the aggregate, reasonably be expected to have a Material Adverse Effect on IBKC, each Subsidiary of IBKC (an “IBKC Subsidiary”) (i) is duly organized and validly existing under the laws of its jurisdiction of organization, (ii) is duly licensed or qualified to do business and, where such concept is recognized under applicable law, in good standing in all jurisdictions (whether federal, state, local or foreign) where its ownership, leasing or operation of property or the conduct of its business requires it to be so licensed or qualified or in good standing, and (iii) has all requisite corporate power and authority to own, lease or operate its properties and assets and to carry on its business as now conducted. There are no restrictions on the ability of IBKC or any Subsidiary of IBKC to pay dividends or distributions except, in the case of IBKC or a Subsidiary that is a regulated entity, for restrictions on dividends or distributions generally applicable to all similarly regulated entities. IBERIABANK is the only depository institution Subsidiary of IBKC, and the deposit accounts of IBERIABANK are insured by the Federal Deposit Insurance Corporation (the “FDIC”) through the Deposit Insurance Fund (as defined in Section 3(y) of the Federal Deposit Insurance Act of 1950 (the “Bank Merger Act”) to the fullest extent permitted by law, all premiums and assessments required to be paid in connection therewith have been paid when due, and no proceedings for the termination of such insurance are pending or threatened.

A-20

become due), except for those liabilities that are reflected or reserved against on the consolidated balance sheet of IBKC included in its Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2019 (including any notes thereto) and for liabilities incurred in the ordinary course of business consistent with past practice since June 30, 2019, or in connection with this Agreement and the transactions contemplated hereby.

6.3 Shareholders’ Approvals. Each of First Horizon and IBKC shall call, give notice of, convene and hold a meeting of its shareholders (the “First Horizon Meeting” and the “IBKC Meeting,” respectively) as soon as reasonably practicable after the S-4 is declared effective, for the purpose of obtaining (a) the Requisite First Horizon Vote and the Requisite IBKC Vote, respectively, required in connection with this Agreement and the Merger, and (b) if so desired and mutually agreed, a vote upon other matters of the type customarily brought before a meeting of shareholders in connection with the approval of a merger agreement or the transactions contemplated thereby, and each of IBKC and First Horizon shall use its reasonable best efforts to cause such meetings to occur as soon as reasonably practicable and on the same date and at the same time, and to set the same record date for each such meeting. Each of First Horizon and IBKC and their respective Boards of Directors shall use its reasonable best efforts to obtain from the shareholders of First Horizon and IBKC, respectively, the Requisite First Horizon Vote and the Requisite IBKC Vote, respectively, including by communicating to the respective shareholders of First Horizon and IBKC its recommendation (and including such recommendation in the Joint Proxy Statement) that, in the case of First Horizon, the shareholders of First Horizon approve this Agreement and the First Horizon Charter Amendment (the “First Horizon Board Recommendation”), and in the case of IBKC, that the shareholders of IBKC approve this Agreement (the “IBKC Board Recommendation”), First Horizon and each of First Horizon and IBKC and their respective Boards of Directors shall not (i) withhold, withdraw, modify or qualify in a manner adverse to the other party the First Horizon Board Recommendation, in the case of First Horizon, or the IBKC Board Recommendation, in the case of IBKC, (ii) fail to make the First Horizon Board Recommendation, in the case of First Horizon, or the IBKC Board Recommendation, in the case of IBKC, in the Joint Proxy Statement, (iii) adopt, approve, recommend or endorse an Acquisition Proposal or publicly announce an intention to adopt, approve, recommend or endorse an Acquisition Proposal, (iv) fail to publicly and without qualification (A) recommend against any Acquisition Proposal, or (B) reaffirm the First Horizon Board Recommendation, in the case of First Horizon, or the IBKC Board Recommendation, in the case of IBKC, in each case, within ten (10) business days (or such fewer number of days as remains prior to the First Horizon Meeting or the IBKC Meeting, as applicable) after an Acquisition Proposal is made public or any request by the other party to do so, or (v) publicly propose to do any of the foregoing (any of the foregoing a “Recommendation Change”). However, subject to Section 8.1 and Section 8.2, if the Board of Directors of First Horizon or IBKC, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the First Horizon Board Recommendation or the IBKC Board Recommendation, as applicable, such Board of Directors may, in the case of First Horizon, prior to the receipt of the Requisite First Horizon Vote, and in the case of IBKC, prior to the receipt of the Requisite IBKC Vote, submit this Agreement to its shareholders without recommendation (although the resolutions approving this Agreement as of the date hereof may not be rescinded or amended), in which event such Board of Directors may communicate the basis for its lack of a recommendation to its shareholders in the Joint Proxy Statement or an appropriate amendment or supplement thereto to the extent required by law; provided, that such Board of Directors may not take any actions under this sentence unless it (A) gives the other party at least three (3) business days’ prior written notice of its intention to take

A-55

such action and a reasonable description of the event or circumstances giving rise to its determination to take such action (including, in the event such action is taken in response to an Acquisition Proposal, the latest material terms and conditions and the identity of the third party in any such Acquisition Proposal, or any amendment or modification thereof, or describe in reasonable detail such other event or circumstances), and (B) at the end of such notice period, takes into account any amendment or modification to this Agreement proposed by the other party and, after receiving the advice of its outside counsel and, with respect to financial matters, its financial advisors, determines in good faith that it would nevertheless more likely than not result in a violation of its fiduciary duties under applicable law to make or continue to make the First Horizon Board Recommendation or IBKC Board Recommendation, as the case may be. Any material amendment to any Acquisition Proposal will be deemed to be a new Acquisition Proposal for purposes of this Section 6.3 and will require a new notice period as referred to in this Section 6.3. First Horizon or IBKC shall adjourn or postpone the First Horizon Meeting or the IBKC Meeting, as the case may be, if, as of the time for which such meeting is originally scheduled there are insufficient shares of First Horizon Common Stock or IBKC Common Stock, as the case may be, represented (either in person or by proxy) to constitute a quorum necessary to conduct the business of such meeting, or if on the date of such meeting IBKC or First Horizon, as applicable, has not received proxies representing a sufficient number of shares necessary to obtain the Requisite IBKC Vote or the Requisite First Horizon Vote, and subject to the terms and conditions of this Agreement, IBKC or First Horizon, as applicable, shall continue to use reasonable best efforts to solicit proxies from its shareholders in order to obtain the Requisite IBKC Vote or Requisite First Horizon Vote, respectively. Notwithstanding anything to the contrary in this Agreement, but subject to the obligation to adjourn or postpone such meeting as set forth in the immediately preceding sentence, unless this Agreement has been terminated in accordance with its terms, (x) the First Horizon Meeting shall be convened and this Agreement and the First Horizon Charter Amendment shall be submitted to the shareholders of First Horizon at the First Horizon Meeting, and (y) the IBKC Meeting shall be convened and this Agreement shall be submitted to the shareholders of IBKC at the IBKC Meeting, and nothing contained in this Agreement shall be deemed to relieve either First Horizon or IBKC of such obligation.

6.4 Legal Conditions to Merger. Subject in all respects to Section 6.1 of this Agreement, each of First Horizon and IBKC shall, and shall cause its Subsidiaries to, use their reasonable best efforts (a) to take, or cause to be taken, all actions necessary, proper or advisable to comply promptly with all legal requirements that may be imposed on such party or its Subsidiaries with respect to the Merger and the Bank Merger and, subject to the conditions set forth in Article VII hereof, to consummate the transactions contemplated by this Agreement, (b) to obtain (and to cooperate with the other party to obtain) any material consent, authorization, order or approval of, or any exemption by, any Governmental Entity and any other third party that is required to be obtained by IBKC or First Horizon or any of their respective Subsidiaries in connection with the Merger, the Bank Merger and the other transactions contemplated by this Agreement, and (c) to obtain the tax opinions referenced in Section 7.2(c) and Section 7.3(c), including by executing and delivering representations contained in certificates of officers of First Horizon and IBKC reasonably satisfactory in form and substance to First Horizon’s and IBKC’s counsel.

6.5 Stock Exchange Listing. First Horizon shall cause the shares of First Horizon Common Stock and New First Horizon Preferred Stock (or depositary shares in respect thereof) to be issued in the Merger to be approved for listing on the NYSE, subject to official notice of issuance, prior to the Effective Time.

6.6 Employee Matters.

(a) From and after the Effective Time, unless otherwise mutually determined by IBKC and First Horizon prior to the Effective Time, First Horizon shall provide generally to employees of IBKC and its Subsidiaries who at the Effective Time become employees of First Horizon or its Subsidiaries (the “Continuing Employees”), employee compensation and benefits under the First Horizon Benefit Plans on terms and conditions that are substantially comparable in the aggregate as those that apply to similarly situated First Horizon employees. Notwithstanding the foregoing, First Horizon and

A-56

IBKC agree that, during the period commencing at the Effective Time and ending on the eighteen (18)-month anniversary thereof, any continuing employee of First Horizon, IBKC or any of their respective Subsidiaries who is involuntarily terminated during such eighteen (18)-month period will be provided with severance as described in Section 6.6(a) of the First Horizon Disclosure Schedule.

(b) For purposes of eligibility, participation, vesting and benefit accrual (except not for purposes of benefit accrual under any defined benefit pension plan or to the extent that such credit would result in a duplication of benefits) under the First Horizon Benefit Plans and the IBKC Benefit Plans, service with or credited by First Horizon, IBKC or any of their respective Subsidiaries or predecessors for Continuing Employees or continuing employees of First Horizon or its Subsidiaries shall be treated as service with First Horizon to the same extent that such service was taken into account under the analogous IBKC Benefit Plan or First Horizon Benefit Plan prior to the Effective Time. With respect to any IBKC Benefit Plan or First Horizon Benefit Plan in which any employees of First Horizon or IBKC (or their Subsidiaries) prior to the Effective Time first become eligible to participate on or after the Effective Time, and in which such employees did not participate prior to the Effective Time, First Horizon, IBKC and the Surviving Entity shall: (i) waive all preexisting conditions, exclusions and waiting periods with respect to participation and coverage requirements applicable to such employees and their eligible dependents, except to the extent such pre-existing conditions, exclusions or waiting periods would apply under the analogous First Horizon Benefit Plan or IBKC Benefit Plan, as the case may be, and (ii) provide each such employee and his or her eligible dependents with credit for any co-payments and deductibles paid prior to the Effective Time under a First Horizon Benefit Plan or IBKC Benefit Plan (to the same extent that such credit was given under the analogous IBKC or First Horizon Benefit Plan) in satisfying any applicable deductible or out-of-pocket requirements under any IBKC Benefit Plan or First Horizon Benefit Plan in which such employee first become eligible to participate after the Effective Time.

(c) The Surviving Entity agrees to honor in accordance with their terms all First Horizon Benefit Plans and IBKC Benefit Plans. IBKC and First Horizon agree that the transactions contemplated by this Agreement shall constitute a “change in control”, “change of control” or other similar concept under any IBKC Benefit Plan, and prior to the Effective Time the Board of Directors of IBKC shall be empowered to take such action as necessary to declare such status under such plans.

(d) If requested by First Horizon in writing delivered to IBKC not less than ten (10) business days before the Closing Date, the Board of Directors of IBKC (or the appropriate committee thereof) shall adopt resolutions and take such corporate action as is necessary or appropriate to terminate the IBKC Banks, Inc. 401(k) Plan (the “IBKC 401(k) Plan”), effective as of the day prior to the Closing Date and contingent upon the occurrence of the Effective Time. If First Horizon requests that the IBKC 401(k) Plan be terminated, (i) IBKC shall provide First Horizon with evidence that such plan has been terminated (the form and substance of which shall be subject to reasonable review and comment by First Horizon) not later than two (2) days immediately preceding the Closing Date, and (ii) the Continuing Employees shall be eligible to participate, effective as of the Effective Time, in a 401(k) plan sponsored or maintained by First Horizon or one of its Subsidiaries (the “First Horizon 401(k) Plan”), it being agreed that there shall be no gap in participation in a tax-qualified defined contribution plan. First Horizon and IBKC shall take any and all actions as may be required, including amendments to the IBKC 401(k) Plan and/or the First Horizon 401(k) Plan, to permit the Continuing Employees to make rollover contributions to the First Horizon 401(k) Plan of “eligible rollover distributions” (within the meaning of Section 401(a)(31) of the Code) in the form of cash, notes (in the case of loans), First Horizon Common Stock or a combination thereof in an amount equal to the full account balance distributed to such employee from the IBKC 401(k) Plan.

(e) Nothing in this Agreement shall confer upon any employee, officer, director or consultant of First Horizon or IBKC or any of their Subsidiaries or affiliates any right to continue in the employ or service of the Surviving Entity, IBKC, First Horizon or any Subsidiary or affiliate thereof, or shall interfere with or restrict in any way the rights of the Surviving Entity, IBKC, First Horizon or any Subsidiary or affiliate thereof to discharge or terminate the services of any employee, officer, director or consultant of First Horizon or IBKC or any of their Subsidiaries or affiliates at any time

A-57

for any reason whatsoever, with or without cause. Nothing in this Agreement shall be deemed to (i) establish, amend, or modify any IBKC Benefit Plan or First Horizon Benefit Plan or any other benefit or employment plan, program, agreement or arrangement, or (ii) alter or limit the ability of the Surviving Entity or any of its Subsidiaries or affiliates to amend, modify or terminate any particular IBKC Benefit Plan or First Horizon Benefit Plan or any other benefit or employment plan, program, agreement or arrangement after the Effective Time. Without limiting the generality of Section 9.11, nothing in this Agreement, express or implied, is intended to or shall confer upon any person, including any current or former employee, officer, director or consultant of First Horizon or IBKC or any of their Subsidiaries or affiliates, any right, benefit or remedy of any nature whatsoever under or by reason of this Agreement.

6.7 Indemnification; Directors’ and Officers’ Insurance.

(a) From and after the Effective Time, the Surviving Entity shall indemnify and hold harmless and shall advance expenses as incurred, in each case, to the fullest extent permitted by applicable law, the IBKC Articles, the IBKC Bylaws and the governing or organizational documents of any IBKC Subsidiary, each present and former director, officer or employee of IBKC and its Subsidiaries (in each case, when acting in such capacity) (collectively, the “IBKC Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, damages or liabilities incurred in connection with any threatened or actual claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, whether arising before or after the Effective Time, arising out of, or pertaining to, the fact that such person is or was a director, officer or employee of IBKC or any of its Subsidiaries or is or was serving at the request of IBKC or any of its Subsidiaries as a director or officer of another person and pertaining to matters, acts or omissions existing or occurring at or prior to the Effective Time, including matters, acts or omissions occurring in connection with the approval of this Agreement and the transactions contemplated by this Agreement; provided, that in the case of advancement of expenses, any IBKC Indemnified Party to whom expenses are advanced provides an undertaking to repay such advances if it is ultimately determined that such IBKC Indemnified Party is not entitled to indemnification. The Surviving Entity shall reasonably cooperate with the IBKC Indemnified Parties, and the IBKC Indemnified Parties shall reasonably cooperate with the Surviving Entity, in the defense of any such claim, action, suit, proceeding or investigation. Without limiting the indemnification and other rights provided in this clause (a), all rights to indemnification and all limitations on liability existing in favor of the IBKC Indemnified Parties as provided in any indemnification agreement in existence on the date of this Agreement shall survive the Merger and shall continue in full force and effect to the fullest extent permitted by law, and shall be honored by the Surviving Entity and its Subsidiaries or their respective successors as if they were the indemnifying party thereunder, without any amendment thereto.

(b) For a period of six (6) years after the Effective Time, the Surviving Entity shall cause to be maintained in effect the current policies of directors’ and officers’ liability insurance maintained by IBKC (provided, that the Surviving Entity may substitute therefor policies with a substantially comparable insurer of at least the same coverage and amounts containing terms and conditions that are no less advantageous to the insured) with respect to claims against the present and former officers and directors of IBKC or any of its Subsidiaries arising from facts or events which occurred at or before the Effective Time (including the approval of the transactions contemplated by this Agreement); provided, however, that the Surviving Entity shall not be obligated to expend, on an annual basis, an amount in excess of 300% of the current annual premium paid as of the date hereof by IBKC for such insurance (the “Premium Cap”), and if such premiums for such insurance would at any time exceed the Premium Cap, then the Surviving Entity shall cause to be maintained policies of insurance which, in the Surviving Entity’s good faith determination, provide the maximum coverage available at an annual premium equal to the Premium Cap. In lieu of the foregoing, First Horizon or IBKC, in consultation with, but only upon the consent, of First Horizon, may (and at the request of First Horizon, IBKC shall use its reasonable best efforts to) obtain at or prior to the Effective Time a six (6)-year “tail” policy under IBKC’s existing directors’ and officers’ insurance policy providing equivalent coverage to that described in the preceding sentence if and to the extent

A-58

that the same may be obtained for an amount that, in the aggregate, does not exceed the Premium Cap.

(c) The obligations of the Surviving Entity, First Horizon or IBKC under this Section 6.7 shall not be terminated or modified after the Effective Time in a manner so as to adversely affect any IBKC Indemnified Party or any other person entitled to the benefit of this Section 6.7 without the prior written consent of the affected IBKC Indemnified Party or affected person.

(d) The provisions of this Section 6.7 shall survive the Effective Time and are intended to be for the benefit of, and shall be enforceable by, each IBKC Indemnified Party and his or her heirs and representatives. If the Surviving Entity or any of its successors or assigns (i) consolidates with or merges into any other person and is not the continuing or surviving entity of such consolidation or merger, or (ii) transfers all or substantially all of its assets or deposits to any other person or engages in any similar transaction, then in each such case, the Surviving Entity will cause proper provision to be made so that the successors and assigns of the Surviving Entity will expressly assume the obligations set forth in this Section 6.7.

6.8 Additional Agreements. In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement (including any merger between a Subsidiary of First Horizon, on the one hand, and a Subsidiary of IBKC, on the other hand) or to vest the Surviving Entity with full title to all properties, assets, rights, approvals, immunities and franchises of any of the parties to the Merger or the Bank Merger, the proper officers and directors of each party to this Agreement and their respective Subsidiaries shall take all such necessary action as may be reasonably requested by First Horizon.

6.9 Advice of Changes. First Horizon and IBKC shall each promptly advise the other party of any effect, change, event, circumstance, condition, occurrence or development (i) that has had or would reasonably be expected to have, either individually or in the aggregate, a Material Adverse Effect on such first party, or (ii) that such first party believes would or would reasonably be expected to cause or constitute a material breach of any of its representations, warranties, obligations, covenants or agreements contained in this Agreement that reasonably could be expected to give rise, individually or in the aggregate, to the failure of a condition in Article VII; provided, that any failure to give notice in accordance with the foregoing with respect to any breach shall not be deemed to constitute a violation of this Section 6.9 or the failure of any condition set forth in Section 7.2 or 7.3 to be satisfied, or otherwise constitute a breach of this Agreement by the party failing to give such notice, in each case, unless the underlying breach would independently result in a failure of the conditions set forth in Section 7.2 or 7.3 to be satisfied; and provided, further, that the delivery of any notice pursuant to this Section 6.9 shall not cure any breach of, or noncompliance with, any other provision of this Agreement or limit the remedies available to the party receiving such notice.

6.10 Dividends. After the date of this Agreement and to the extent permitted under the First Horizon Charter and the IBKC Articles, respectively, each of First Horizon and IBKC shall coordinate with the other the declaration of any dividends in respect of First Horizon Common Stock, First Horizon Preferred Stock, IBKC Common Stock and IBKC Preferred Stock and the record dates and payment dates relating thereto, it being the intention of the parties hereto that holders of IBKC Common Stock and holders of IBKC Preferred Stock shall not receive two dividends, or fail to receive one dividend, in any quarter with respect to their shares of IBKC Common Stock or IBKC Preferred Stock and any shares of First Horizon Common Stock or New First Horizon Preferred Stock any such holder receives in exchange therefor in the Merger.

6.11 Shareholder Litigation. Each party shall give the other party prompt notice of any shareholder litigation against such party or its directors or officers relating to the transactions contemplated by this Agreement, and shall give the other party the opportunity to participate (at such other party’s expense) in the defense or settlement of any such litigation. Each party shall give the other a reasonable opportunity to review and comment on all filings or responses to be made by such party in connection with any such litigation, and will in good faith take such comments into account. No party shall agree to settle any such litigation without the other party’s prior written consent, which

A-59

consent shall not be unreasonably withheld, conditioned or delayed; provided, that the other party shall not be obligated to consent to any settlement which does not include a full release of such other party and its affiliates or which imposes an injunction or other equitable relief after the Effective Time upon the Surviving Entity or any of its affiliates.

6.12 Corporate Governance; Headquarters.

(a) Prior to the Effective Time, the Board of Directors of First Horizon shall take all actions necessary to adopt the First Horizon Bylaw Amendment effective as of and from and after the Effective Time and to effect the requirements referenced therein. The provisions of Section 3.17 of such bylaws shall also be considered an agreement of the parties in this Agreement mutatis mutandis. Effective as of the Effective Time, in accordance with the First Horizon Bylaw Amendment, the number of directors that will comprise the entire Board of Directors of the Surviving Entity and the entire Board of Directors of First Horizon Bank shall each be seventeen (17).

(b) In accordance with, and to the extent provided in, the First Horizon Bylaw Amendment: (i) effective as of the Effective Time, Mr. D.

6.13 Commitments to the Community

(a) Prior to the Closing Date, IBKC shall use its reasonable best efforts to establish a new charitable foundation, incorporating the name “Louisiana First Horizon” (the “Foundation”), focused on community support in the State of Louisiana. The initial members of the board of trustees of the Foundation will be selected by the Board of Directors of IBKC and the Board of Directors of First Horizon prior to the Closing Date, with the Board of Directors of First Horizon entitled to select one (1) initial member and the Board of Directors of IBKC entitled to select the remaining initial

A-60

members. On the Closing Date, the Surviving Entity shall contribute to the Foundation an amount in cash equal to $20,000,000.

(b) As of the Effective Time, the headquarters for the Surviving Entity’s and First Horizon Bank’s regional banking business will be located in New Orleans, Louisiana.

6.14 Acquisition Proposals.

(a) Each party agrees that it will not, and will cause each of its Subsidiaries and use its reasonable best efforts to cause its and their respective officers, directors, employees, agents, advisors and representatives (collectively, “Representatives”) not to, directly or indirectly, (i) initiate, solicit, knowingly encourage or knowingly facilitate any inquiries or proposals with respect to any Acquisition Proposal, (ii) engage or participate in any negotiations with any person concerning any Acquisition Proposal, (iii) provide any confidential or nonpublic information or data to, or have or participate in any discussions with, any person relating to any Acquisition Proposal (except to notify a person that has made or, to the knowledge of such party, is making any inquiries with respect to, or is considering making, an Acquisition Proposal, of the existence of the provisions of this Section 6.14), or (iv) unless this Agreement has been terminated in accordance with its terms, approve or enter into any term sheet, letter of intent, commitment, memorandum of understanding, agreement in principle, acquisition agreement, merger agreement or other similar agreement (whether written or oral, binding or nonbinding) (other than an Acceptable Confidentiality Agreement entered into in accordance with this Section 6.14) in connection with or relating to any Acquisition Proposal. Notwithstanding the foregoing, in the event that after the date of this Agreement and prior to the receipt of the Requisite First Horizon Vote, in the case or First Horizon, or the Requisite IBKC Vote, in the case of IBKC, a party receives an unsolicited bona fide written Acquisition Proposal, such party may, and may permit its Subsidiaries and its and its Subsidiaries’ Representatives to, furnish or cause to be furnished confidential or nonpublic information or data and participate in such negotiations or discussions with the person making the Acquisition Proposal if the Board of Directors of such party concludes in good faith (after receiving the advice of its outside counsel, and with respect to financial matters, its financial advisors) that failure to take such actions would be more likely than not to result in a violation of its fiduciary duties under applicable law; provided, that, prior to furnishing any confidential or nonpublic information permitted to be provided pursuant to this sentence, such party shall have provided such information to the other party to this Agreement and shall have entered into a confidentiality agreement with the person making such Acquisition Proposal on terms no less favorable to it than the Confidentiality Agreement (“Acceptable Confidentiality Agreement”), which confidentiality agreement shall not provide such person with any exclusive right to negotiate with such party. Each party will, and will cause its Representatives to, immediately cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any person other than IBKC or First Horizon, as applicable, with respect to any Acquisition Proposal. Each party will promptly (within twenty-four (24) hours) advise the other party following receipt of any Acquisition Proposal or any inquiry which could reasonably be expected to lead to an Acquisition Proposal, and the substance thereof (including the material terms and conditions of and the identity of the person making such inquiry or Acquisition Proposal), will provide the other party with an unredacted copy of any such Acquisition Proposal and any draft agreements, proposals or other materials received in connection with any such inquiry or Acquisition Proposal, and will keep the other party reasonably apprised of any related developments, discussions and negotiations on a current basis, including any amendments to or revisions of the material terms of such inquiry or Acquisition Proposal. Each party shall use its reasonable best efforts to enforce any existing confidentiality or standstill agreements to which it or any of its Subsidiaries is a party in accordance with the terms thereof. As used in this Agreement, “Acquisition Proposal” shall mean, with respect to First Horizon or IBKC, as applicable, other than the transactions contemplated by this Agreement, any offer, proposal or inquiry relating to, or any third-party indication of interest in, (i) any acquisition or purchase, direct or indirect, of twenty-five percent (25%) or more of the consolidated assets of a party and its Subsidiaries or twenty-five percent (25%) or more of any class of equity or voting securities of a party or its Subsidiaries whose assets, individually or in the

A-61

aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party, (ii) any tender offer (including a self-tender offer) or exchange offer that, if consummated, would result in such third party beneficially owning twenty-five percent (25%) or more of any class of equity or voting securities of a party or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party, or (iii) a merger, consolidation, share exchange, business combination, reorganization, recapitalization, liquidation, dissolution or other similar transaction involving a party or its Subsidiaries whose assets, individually or in the aggregate, constitute twenty-five percent (25%) or more of the consolidated assets of the party.

(b) Nothing contained in this Agreement shall prevent a party or its Board of Directors from complying with Rule 14d-9 and Rule 14e-2 under the Exchange Act or Item 1012(a) of Regulation M-A with respect to an Acquisition Proposal or from making any legally required disclosure to such party’s shareholders; provided, that such rules will in no way eliminate or modify the effect that any action pursuant to such rules would otherwise have under this Agreement.

6.15 Public Announcements. IBKC and First Horizon agree that the initial press release with respect to the execution and delivery of this Agreement shall be a release mutually agreed to by the parties. Thereafter, each of the parties agrees that no public release or announcement or statement concerning this Agreement or the transactions contemplated hereby shall be issued by any party without the prior written consent of the other party (which consent shall not be unreasonably withheld, conditioned or delayed), except (i) as required by applicable law or the rules or regulations of any applicable Governmental Entity or stock exchange to which the relevant party is subject, in which case the party required to make the release or announcement shall consult with the other party about, and allow the other party reasonable time to comment on, such release or announcement in advance of such issuance, or (ii) for such releases, announcements or statements that are consistent with other such releases, announcement or statements made after the date of this Agreement in compliance with this Section 6.15.

6.16 Change of Method. IBKC and First Horizon shall be empowered, upon their mutual agreement, at any time prior to the Effective Time, to change the method or structure of effecting the combination of IBKC and First Horizon (including the provisions of Article I), if and to the extent they both deem such change to be necessary, appropriate or desirable; provided, however, that no such change shall (i) alter or change the Exchange Ratio or the number of shares of First Horizon Common Stock received by holders of IBKC Common Stock in exchange for each share of IBKC Common Stock, (ii) adversely affect the Tax treatment of IBKC’s shareholders or First Horizon’s shareholders pursuant to this Agreement, (iii) adversely affect the Tax treatment of IBKC or First Horizon pursuant to this Agreement, or (iv) materially impede or delay the consummation of the transactions contemplated by this Agreement in a timely manner. The parties agree to reflect any such change in an appropriate amendment to this Agreement executed by both parties in accordance with Section 9.1.

6.17 Restructuring Efforts. If either IBKC or First Horizon shall have failed to obtain the Requisite IBKC Vote or the Requisite First Horizon Vote at the duly convened IBKC Meeting or First Horizon Meeting, as applicable, or any adjournment or postponement thereof, each of the parties shall in good faith use its reasonable best efforts to negotiate a restructuring of the transactions provided for in this Agreement (it being understood that neither party shall have any obligation to alter or change any material terms, including the amount or kind of the consideration to be issued to holders of the capital stock of IBKC as provided for in this Agreement, or any term that would adversely affect the tax treatment of the transactions contemplated hereby, in a manner adverse to such party or its shareholders) and/or resubmit this Agreement and the transactions contemplated hereby (or as restructured pursuant to this Section 6.17) to its respective shareholders for approval.

6.18 Takeover Statutes. None of IBKC, First Horizon or their respective Boards of Directors shall take any action that would cause any Takeover Statute to become applicable to this Agreement, the Merger, or any of the other transactions contemplated hereby, and each shall take all necessary steps to exempt (or ensure the continued exemption of) the Merger and the other transactions

A-62

contemplated hereby from any applicable Takeover Statute now or hereafter in effect. If any Takeover Statute may become, or may purport to be, applicable to the transactions contemplated hereby, each party and the members of their respective Boards of Directors will grant such approvals and take such actions as are necessary so that the transactions contemplated by this Agreement may be consummated as promptly as practicable on the terms contemplated hereby and otherwise act to eliminate or minimize the effects of any Takeover Statute on any of the transactions contemplated by this Agreement, including, if necessary, challenging the validity or applicability of any such Takeover Statute.

6.19 Treatment of IBKC Indebtedness. At and after the Effective Time, First Horizon shall assume the due and punctual performance and observance of the covenants to be performed by IBKC under the indentures set forth on Section 6.19 of the IBKC Disclosure Schedule, and the due and punctual payment of the principal of (and premium, if any) and interest on, the notes governed thereby. In connection therewith, prior to the Effective Time, First Horizon and IBKC shall cooperate and use reasonable best efforts to execute and deliver any supplemental indentures, officer’s certificates or other documents, and the parties hereto shall cooperate and use reasonable best efforts to provide any opinion of counsel to the trustee thereof, required to make such assumption effective as of the Effective Time.

6.20 Amendment of First Horizon Charter. Prior to the Effective Time, subject to the Requisite First Horizon Vote, First Horizon shall amend the First Horizon Charter to effect an increase in the number of authorized shares of First Horizon Common Stock from 400,000,000 to 700,000,000.

6.21 IBKC Series D Preferred Stock. Prior to the Effective Time, IBKC shall use its reasonable best efforts to solicit the consent of the holders of the IBKC Series D Preferred Stock and any other securityholders of IBKC required to either (a) effect an amendment of the terms of the IBKC Series D Preferred Stock, or (b) modify the terms of the First Horizon Series D Preferred Stock, in each case, to extend the Optional Redemption (as defined in Article 4, Section F of the IBKC Articles or the corresponding terms of the First Horizon Series D Preferred Stock, as applicable) to a date which is at least five (5) years from the Closing Date of the Merger. For the avoidance of doubt, the receipt by IBKC of the foregoing consent shall not be a condition to the respective obligations of the parties to effect the Merger.

6.22 Exemption from Liability Under Section 16(b). IBKC and First Horizon agree that, in order to most effectively compensate and retain IBKC Insiders, both prior to and after the Effective Time, it is desirable that IBKC Insiders not be subject to a risk of liability under Section 16(b) of the Exchange Act to the fullest extent permitted by applicable law in connection with the conversion of shares of IBKC Common Stock and IBKC Preferred Stock and IBKC PSU Awards into shares of First Horizon Common Stock and New First Horizon Preferred Stock in the Merger and the conversion of IBKC Equity Awards into corresponding First Horizon Equity Awards in the Merger, and for that compensatory and retentive purpose agree to the provisions of this Section 6.22. IBKC shall deliver to First Horizon in a reasonably timely fashion prior to the Effective Time accurate information regarding those officers and directors of IBKC subject to the reporting requirements of Section 16(a) of the Exchange Act (the “IBKC Insiders”), and the Board of Directors of First Horizon and of IBKC, or a committee of non-employee directors thereof (as such term is defined for purposes of Rule 16b-3(d) under the Exchange Act), shall reasonably promptly thereafter, and in any event prior to the Effective Time, take all such steps as may be required to cause (in the case of IBKC) any dispositions of IBKC Common Stock, IBKC Preferred Stock or IBKC Equity Awards by the IBKC Insiders, and (in the case of First Horizon) any acquisitions of First Horizon Common Stock, New First Horizon Preferred Stock, or First Horizon Equity Awards by any IBKC Insiders who, immediately following the Merger, will be officers or directors of the Surviving Entity subject to the reporting requirements of Section 16(a) of the Exchange Act, in each case, pursuant to the transactions contemplated by this Agreement, to be exempt from liability pursuant to Rule 16b-3 under the Exchange Act to the fullest extent permitted by applicable law.

ARTICLE VIII

T ERMINATION AND A MENDMENT

8.1 Termination. This Agreement may be terminated at any time prior to the Effective Time, whether before or after receipt of the Requisite IBKC Vote or the Requisite First Horizon Vote:

(a) by mutual written consent of First Horizon and IBKC;

(b) by either First Horizon or IBKC if any Governmental Entity that must grant a Requisite Regulatory Approval has denied approval of the Merger or the Bank Merger and such denial has become final and nonappealable or any Governmental Entity of competent jurisdiction shall have issued a final and nonappealable order, injunction, decree or other legal restraint or prohibition permanently enjoining or otherwise prohibiting or making illegal the consummation of the Merger or the Bank Merger, unless the failure to obtain a Requisite Regulatory Approval shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein;

(c) by either First Horizon or IBKC if the Merger shall not have been consummated on or before the twelve (12) month anniversary of the date of this Agreement (the “Termination Date”), unless the failure of the Closing to occur by such date shall be due to the failure of the party seeking to terminate this Agreement to perform or observe the obligations, covenants and agreements of such party set forth herein;

(d) by either First Horizon or IBKC (provided, that the terminating party is not then in material breach of any representation, warranty, obligation, covenant or other agreement contained herein) if there shall have been a breach of any of the obligations, covenants or agreements or any of the representations or warranties (or any such representation or warranty shall cease to be true) set forth in this Agreement on the part of IBKC, in the case of a termination by First Horizon, or First Horizon, in the case of a termination by IBKC, which breach or failure to be true, either individually or in the aggregate with all other breaches by such party (or failures of such representations or warranties to be true), would constitute, if occurring or continuing on the Closing Date, the failure of a condition set forth in Section 7.2, in the case of a termination by First Horizon, or Section 7.3, in the case of a termination by IBKC, and which is not cured within forty-five (45) days following written notice to IBKC, in the case of a termination by First Horizon, or First Horizon, in the case of a termination by IBKC, or by its nature or timing cannot be cured during such period (or such fewer days as remain prior to the Termination Date);

(e) by IBKC, if (i) First Horizon or the Board of Directors of First Horizon shall have made a Recommendation Change, or (ii) First Horizon or the Board of Directors of First Horizon shall have breached its obligations under Section 6.3 or 6.14 in any material respect; or

8.2 Effect of Termination.

(a) In the event of termination of this Agreement by either First Horizon or IBKC as provided in Section 8.1, this Agreement shall forthwith become void and have no effect, and none of First Horizon, IBKC, any of their respective Subsidiaries or any of the officers or directors of any of them shall have any liability of any nature whatsoever hereunder, or in connection with the transactions contemplated hereby, except that (i) Section 6.2(b) (Access to Information;

A-66

Confidentiality), Section 6.15 (Public Announcements), this Section 8.2 and Article IX (other than Section 9.12) shall survive any termination of this Agreement, and (ii) notwithstanding anything to the contrary contained in this Agreement, neither First Horizon nor IBKC shall be relieved or released from any liabilities or damages arising out of its fraud or its willful and material breach of any provision of this Agreement. “Willful and material breach” shall mean a material breach of, or material failure to perform any of the covenants or other agreements contained in, this Agreement that is a consequence of an act or failure to act by the breaching or non-performing party with actual knowledge that such party’s act or failure to act would, or would reasonably be expected to, result in or constitute such breach of or such failure of performance under this Agreement.

(b) (i) In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of IBKC or shall have been made directly to the shareholders of IBKC or any person shall have publicly announced (and not withdrawn at least two (2) business days prior to the IBKC Meeting) an Acquisition Proposal, in each case, with respect to IBKC, and (A) (x) thereafter this Agreement is terminated by either First Horizon or IBKC pursuant to Section 8.1(c) without the Requisite IBKC Vote having been obtained (and all other conditions set forth in Section 7.1 and Section 7.3 were satisfied or were capable of being satisfied prior to such termination), or (y) thereafter this Agreement is terminated by First Horizon pursuant to Section 8.1(d) as a result of a willful and material breach, and (B) prior to the date that is twelve (12) months after the date of such termination, IBKC enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then IBKC shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay First Horizon, by wire transfer of same-day funds, a fee equal to $156,000,000 (the “Termination Fee”); provided, that for purposes of this Section 8.2(b)(i), all references in the definition of Acquisition Proposal to “twenty-five percent (25%)” shall instead refer to “fifty percent (50%).”

(ii) In the event that this Agreement is terminated by First Horizon pursuant to Section 8.1(f), then IBKC shall pay First Horizon, by wire transfer of same-day funds, the Termination Fee within two (2) business days of the date of termination.

(c) (i) In the event that after the date of this Agreement and prior to the termination of this Agreement, a bona fide Acquisition Proposal shall have been communicated to or otherwise made known to the Board of Directors or senior management of First Horizon or shall have been made directly to the shareholders of First Horizon or any person shall have publicly announced (and not withdrawn at least two (2) business days prior to the First Horizon Meeting) an Acquisition Proposal, in each case, with respect to First Horizon, and (A) (x) thereafter this Agreement is terminated by either First Horizon or IBKC pursuant to Section 8.1(c) without the Requisite First Horizon Vote having been obtained (and all other conditions set forth in Section 7.1 and Section 7.2 were satisfied or were capable of being satisfied prior to such termination), or (y) thereafter this Agreement is terminated by IBKC pursuant to Section 8.1(d) as a result of a willful and material breach, and (B) prior to the date that is twelve (12) months after the date of such termination, First Horizon enters into a definitive agreement or consummates a transaction with respect to an Acquisition Proposal (whether or not the same Acquisition Proposal as that referred to above), then First Horizon shall, on the earlier of the date it enters into such definitive agreement and the date of consummation of such transaction, pay IBKC the Termination Fee by wire transfer of same-day funds; provided, that for purposes of this Section 8.2(c)(i), all references in the definition of Acquisition Proposal to “twenty-five percent (25%)” shall instead refer to “fifty percent (50%).”

(ii) In the event that this Agreement is terminated by IBKC pursuant to Section 8.1(e), then First Horizon shall pay IBKC, by wire transfer of same-day funds, the Termination Fee within two (2) business days of the date of termination.

(d) Notwithstanding anything to the contrary in this Agreement, but without limiting the right of any party to recover liabilities or damages arising out of the other party’s fraud or willful and

A-67

material breach of any provision of this Agreement, in no event shall either party be required to pay the Termination Fee more than once.

(e) Each of First Horizon and IBKC acknowledges that the agreements contained in this Section 8.2 are an integral part of the transactions contemplated by this Agreement, and that, without these agreements, the other party would not enter into this Agreement; accordingly, if First Horizon or IBKC, as the case may be, fails promptly to pay the amount due pursuant to this Section 8.2, and, in order to obtain such payment, the other party commences a suit which results in a judgment against the non-paying party for the Termination Fee or any portion thereof, such non-paying party shall pay the costs and expenses of the other party (including attorneys’ fees and expenses) in connection with such suit. In addition, if First Horizon or IBKC, as the case may be, fails to pay the amounts payable pursuant to this Section 8.2, then such party shall pay interest on such overdue amounts at a rate per annum equal to the “prime rate” published in the Wall Street Journal on the date on which such payment was required to be made for the period commencing as of the date that such overdue amount was originally required to be paid and ending on the date that such overdue amount is actually paid in full.

November 3, 2019

Board of Directors
First Horizon National Corporation
165 Madison Avenue
Memphis, TN 38103

Members of the Board:

We understand that IBERIABANK Corporation (“Iberia”) and First Horizon National Corporation (“First Horizon”) propose to enter into an Agreement and Plan of Merger, substantially in the form of the draft dated November 3, 2019 (the “Merger Agreement”), which provides, among other things, for the merger (the “Merger”) of Iberia with and into First Horizon, with First Horizon remaining as the surviving entity. Pursuant to the Merger, each outstanding share of common stock, par value $1.00 per share, of Iberia (the “Iberia Common Stock”), other than shares held by Iberia or First Horizon (in each case other than shares of Iberia Common Stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity, that are beneficially owned by third parties or (ii) held, directly or indirectly, by Iberia or First Horizon in respect of debts previously contracted), will be converted into the right to receive 4.584 shares (the “Exchange Ratio”) of common stock, par value $0.625 per share, of First Horizon (the “First Horizon Common Stock”), subject to adjustment in certain circumstances (the “Consideration”). The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to First Horizon.

For purposes of the opinion set forth herein, we have:

1)

Reviewed certain publicly available financial statements and other business and financial information of Iberia and First Horizon, respectively;

2)

Reviewed certain internal financial statements and other financial and operating data concerning Iberia and First Horizon, respectively;

3)

Reviewed the Street Forecasts (as defined below);

4)

Reviewed information relating to certain strategic, financial and operational benefits anticipated from the Merger, prepared by the managements of Iberia and First Horizon, respectively;

5)

Discussed the past and current operations and financial condition and the prospects of Iberia, including information relating to certain strategic, financial and operational benefits anticipated from the Merger, with senior executives of Iberia;

6)

Discussed the past and current operations and financial condition and the prospects of First Horizon, including information relating to certain strategic, financial and operational benefits anticipated from the Merger, with senior executives of First Horizon;

7)

Reviewed the pro forma impact of the Merger on First Horizon’ earnings per share, tangible book value per share, common equity Tier 1 ratio, cash flow, consolidated capitalization and certain financial ratios;

8)

Reviewed the reported prices and trading activity for Iberia Common Stock and First Horizon Common Stock;

9)

Compared the financial performance of Iberia and First Horizon and the prices and trading activity of Iberia Common Stock and First Horizon Common Stock with that of certain other publicly-traded companies comparable with Iberia and First Horizon, respectively, and their securities;

B-1

10)

Reviewed the financial terms, to the extent publicly available, of certain comparable merger transactions;

11)

Participated in discussions and negotiations among representatives of Iberia and First Horizon and their financial and legal advisors;

12)

Reviewed the Merger Agreement and certain related documents; and

13)

Performed such other analyses, reviewed such other information and considered such other factors as we have deemed appropriate.

We have assumed and relied upon, without independent verification, the accuracy and completeness of the information that was publicly available or supplied or otherwise made available to us by Iberia and First Horizon, and formed a substantial basis for this opinion.

At your direction, our analysis relating to the business and financial prospects for Iberia and First Horizon for purposes of this opinion have been made only on the basis of certain financial projections furnished to us by the managements of Iberia and First Horizon, respectively, which were primarily derived from a consensus of selected Wall Street equity research financial forecasts identified by the managements of Iberia and First Horizon, which forecasts were extrapolated for certain fiscal years based on your guidance (such forecasts and extrapolations thereof, the “Street Forecasts”). We have been advised by Iberia and First Horizon, and have assumed, with your consent, that the Street Forecasts are a reasonable basis upon which to evaluate the business and financial prospects of Iberia and First Horizon, respectively, and reflect the best currently available estimates of the future financial performance of Iberia and First Horizon, respectively. We express no view as to the Street Forecasts or the assumptions on which they were based, including the selection of the equity research financial forecasts from which the Street Forecasts were derived.

In addition, we have assumed that the Merger will be consummated in accordance with the terms set forth in the Merger Agreement without any waiver, amendment or delay of any terms or conditions, including, among other things, that the Merger will be treated as a tax-free reorganization, pursuant to the Internal Revenue Code of 1986, as amended, and that the definitive Merger Agreement will not differ in any material respect from the draft thereof furnished to us. Morgan Stanley has assumed that in connection with the receipt of all the necessary governmental, regulatory or other approvals and consents required for the proposed Merger, no delays, limitations, conditions or restrictions will be imposed that would have a material adverse effect on the contemplated benefits expected to be derived in the proposed Merger. We are not legal, tax, or regulatory advisors. We are not experts in the evaluation of allowance for loan losses, and we have neither made an independent evaluation of the adequacy of the allowance for loan losses at Iberia or First Horizon, nor have we examined any individual loan credit files of Iberia or First Horizon or been requested to conduct such a review, and, as a result, we have assumed that the aggregate allowance for loan losses of Iberia and First Horizon, respectively, is adequate. We are financial advisors only and have relied upon, without independent verification, the assessment of First Horizon and Iberia and their legal, tax, or regulatory advisors with respect to legal, tax, or regulatory matters. We express no opinion with respect to the fairness of the amount or nature of the consideration pursuant to the Merger Agreement in respect of any series of preferred stock of Iberia. We express no opinion with respect to the fairness of the amount or nature of the compensation to any of Iberia’s officers, directors or employees, or any class of such persons, relative to the Consideration to be paid to the holders of shares of the Iberia Common Stock in the transaction. We have not made any independent valuation or appraisal of the assets or liabilities of Iberia or First Horizon, nor have we been furnished with any such valuations or appraisals. Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof. Events occurring after the date hereof may affect this opinion and the assumptions used in preparing it, and we do not assume any obligation to update, revise or reaffirm this opinion.

We have acted as financial advisor to the Board of Directors of First Horizon in connection with this transaction and will receive a fee for our services, a substantial portion of which is contingent

B-2

upon the closing of the Merger. In the two years prior to the date hereof, we have provided financial advisory and financing services for First Horizon and have received fees in connection with such services. Morgan Stanley may also seek to provide financial advisory and financing services to First Horizon, Iberia and their respective affiliates in the future and would expect to receive fees for the rendering of these services.

Please note that Morgan Stanley is a global financial services firm engaged in the securities, investment management and individual wealth management businesses. Our securities business is engaged in securities underwriting, trading and brokerage activities, foreign exchange, commodities and derivatives trading, prime brokerage, as well as providing investment banking, financing and financial advisory services. Morgan Stanley, its affiliates, directors and officers may at any time invest on a principal basis or manage funds that invest, hold long or short positions, finance positions, and may trade or otherwise structure and effect transactions, for their own account or the accounts of its customers, in debt or equity securities or loans of First Horizon, Iberia, or any other company, or any currency or commodity, that may be involved in this transaction, or any related derivative instrument.

This opinion has been approved by a committee of Morgan Stanley investment banking and other professionals in accordance with our customary practice. This opinion is for the information of the Board of Directors of First Horizon and may not be used for any other purpose or disclosed without our prior written consent, except that a copy of this opinion may be included in its entirety in any filing First Horizon is required to make with the Securities and Exchange Commission in connection with this transaction if such inclusion is required by applicable law. In addition, this opinion does not in any manner address the prices at which First Horizon Common Stock will trade following consummation of the Merger or at any time and Morgan Stanley expresses no opinion or recommendation as to how the shareholders of First Horizon and the Company should vote at the shareholders’ meetings to be held in connection with the Merger.

Based on and subject to the foregoing, we are of the opinion on the date hereof that the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to First Horizon.

Very truly yours,

MORGAN STANLEY & CO. LLC

November 3, 2019

The Board of Directors
IBERIABANK Corporation
200 West Congress Street
Lafayette, Louisiana 70501

Members of the Board:

You have requested the opinion of Keefe, Bruyette & Woods, Inc. (“KBW” or “we”) as investment bankers as to the fairness, from a financial point of view, to the common stockholders of IBERIABANK Corporation (“IBKC”) of the Exchange Ratio (as defined below) in the proposed merger (the “Merger”) of IBKC with and into First Horizon National Corporation (“First Horizon”) pursuant to the Agreement and Plan of Merger (the “Agreement”) to be entered into by and between IBKC and First Horizon. Pursuant to the Agreement and subject to the terms, conditions and limitations set forth therein, at the Effective Time (as defined in the Agreement), by virtue of the Merger and without any action on the part of First Horizon, IBKC, or the holder of any securities of IBKC or First Horizon, each share of common stock, par value $1.00 per share, of IBKC (“IBKC Common Stock”) issued and outstanding immediately prior to the Effective Time, except for shares of IBKC Common Stock owned by IBKC or First Horizon (in each case, other than shares of IBKC Common Stock (i) held in trust accounts, managed accounts, mutual funds and the like, or otherwise held in a fiduciary or agency capacity that are beneficially owned by third parties, or (ii) held, directly or indirectly, by IBKC or First Horizon in respect of debts previously contracted), shall be converted into the right to receive 4.584 shares of the common stock, par value $0.625 per share, of First Horizon (“First Horizon Common Stock”). The ratio of 4,584 shares of First Horizon Common Stock for one share of IBKC Common Stock is referred to herein as the “Exchange Ratio.” The terms and conditions of the Merger are more fully set forth in the Agreement.

The Agreement further provides that, promptly following the Effective Time or at such later time and date as specified in a separate bank merger agreement (the “Bank Merger Agreement”), IBERIABANK, a wholly-owned subsidiary of IBKC, will merge with and into First Horizon Bank, a wholly-owned subsidiary of First Horizon, with First Horizon Bank as the surviving entity, pursuant to the Bank Merger Agreement (such transaction, the “Bank Merger”).

KBW has acted as financial advisor to IBKC and not as an advisor to or agent of any other person. As part of our investment banking business, we are continually engaged in the valuation of bank and bank holding company securities in connection with acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for various other purposes. As specialists in the securities of banking companies, we have experience in, and knowledge of, the valuation of banking enterprises. We and our affiliates, in the ordinary course of our and their broker-dealer businesses (and further to existing sales and trading relationships between each of KBW and a KBW broker-dealer affiliate and IBKC), may from time to time purchase securities from, and sell securities to, IBKC and First Horizon. In addition, as a market maker in securities, we and our affiliates may from time to time have a long or short position in, and buy or sell, debt or equity securities of IBKC or First Horizon for our and their own respective accounts and for the accounts of our and their respective customers and clients. KBW employees may also from time to time maintain individual positions in IBKC and First Horizon. As IBKC has

previously been informed by KBW, such positions currently include an individual position in shares of IBKC Common Stock held by a senior member of the KBW advisory team providing services to IBKC in connection with the proposed Merger. We have acted exclusively for the board of directors of IBKC (the “Board”) in rendering this opinion and will receive a fee from IBKC for our services. A portion of our fee is payable upon entering into the Agreement, and a significant portion is contingent upon the successful completion of the Merger. In addition, IBKC has agreed to indemnify us for certain liabilities arising out of our engagement.

In addition to this present engagement, in the past two years, KBW has provided investment banking or financial advisory services to IBKC and received compensation for such services. KBW acted as financial advisor to IBKC in connection with its March 2018 acquisition of Gibraltar Private Bank & Trust Co. In addition, KBW acted as joint book-running manager for IBKC’s March 2019 offering of preferred stock. In the past two years, KBW has not provided investment banking and financial advisory services to First Horizon. We may in the future provide investment banking and financial advisory services to IBKC or First Horizon and receive compensation for such services.

In connection with this opinion, we have reviewed, analyzed and relied upon material bearing upon the financial and operating condition of IBKC and First Horizon and bearing upon the Merger, including among other things, the following: (i) a draft of the Agreement dated November 3, 2019 (the most recent draft made available to us); (ii) the audited financial statements and the Annual Reports on Form 10-K for the three fiscal years ended December 31, 2018 of IBKC; (iii) the unaudited quarterly financial statements and Quarterly Reports on Form 10-Q for the quarters ended March 31, 2019 and June 30, 2019 of IBKC; (iv) certain unaudited quarterly financial results for the quarter ended September 30, 2019 of IBKC (contained in the Current Report on Form 8-K filed by IBKC with the Securities and Exchange Commission on October 18, 2019); (v) the audited financial statements and Annual Reports on Form 10-K for the three fiscal years ended December 31, 2018 of First Horizon; (vi) the unaudited quarterly financial statements and Quarterly Reports on Form 10-Q for the quarters ended March 31, 2019 and June 30, 2019 of First Horizon; (vii) certain unaudited quarterly financial results for the quarter ended September 30, 2019 of First Horizon (contained in the Current Report on Form 8-K filed by First Horizon with the Securities and Exchange Commission on October 16, 2019); (viii) certain regulatory filings of IBKC and First Horizon and their respective subsidiaries, including the quarterly reports on Form FR Y-9C and call reports filed with respect to each quarter during the three-year period ended December 31, 2018 as well as the quarters ended March 31, 2019 and June 30, 2019, and in the case of IBERIABANK and First Horizon Bank, September 30, 2019; (ix) certain other interim reports and other communications of IBKC and First Horizon to their respective shareholders; and (x) other financial information concerning the businesses and operations of IBKC and First Horizon that was furnished to us by IBKC and First Horizon or which we were otherwise directed to use for purposes of our analyses. Our consideration of financial information and other factors that we deemed appropriate under the circumstances or relevant to our analyses included, among others, the following: (i) the historical and current financial position and results of operations of IBKC and First Horizon; (ii) the assets and liabilities of IBKC and First Horizon; (iii) a comparison of certain financial and stock market information for IBKC and First Horizon with similar information for certain other companies the securities of which are publicly traded; (iv) financial and operating forecasts and projections of IBKC that were prepared by IBKC management, provided to and discussed with us by IBKC management, and used and relied upon by us at the direction of such management and with the consent of the Board; (v) financial and operating forecasts and projections of First Horizon with respect to fiscal years 2019 and 2020 that were prepared by First Horizon management, provided to and discussed with us by First Horizon management, and used and relied upon by us based on such

discussions, at the direction of IBKC management and with the consent of the Board; (vi) financial and operating forecasts and projections of First Horizon with respect to certain fiscal years beyond 2020 that were prepared by IBKC management, provided to and discussed with us by IBKC management and used and relied upon by us at the direction of such management and with the consent of the Board; and (vii) estimates regarding certain pro forma financial effects of the Merger on First Horizon (including, without limitation, the cost savings and related expenses expected to result or be derived from the Merger) that were prepared by First Horizon management, provided to and discussed with us by First Horizon management, and used and relied upon by us based on such discussions, at the direction of IBKC management and with the consent of the Board. We have also performed such other studies and analyses as we considered appropriate and have taken into account our assessment of general economic, market and financial conditions and our experience in other transactions, as well as our experience in securities valuation and knowledge of the banking industry generally. We have also participated in discussions held by the managements of IBKC and First Horizon regarding the past and current business operations, regulatory relations, financial condition and future prospects of their respective companies and such other matters as we have deemed relevant to our inquiry.

In conducting our review and arriving at our opinion, we have relied upon and assumed the accuracy and completeness of all of the financial and other information that was provided to us or that was publicly available and we have not independently verified the accuracy or completeness of any such information or assumed any responsibility or liability for such verification, accuracy or completeness. We have relied upon the management of IBKC as to the reasonableness and achievability of the financial and operating forecasts and projections of IBKC and the financial and operating forecasts and projections of First Horizon with respect to certain fiscal years beyond 2020, all as referred to above (and the assumptions and bases for all such information), and we have assumed that all such information has been reasonably prepared on a basis reflecting the best currently available estimates and judgments of such management and that the forecasts, projections and estimates reflected in such information will be realized in the amounts and in the time periods currently estimated by such management. We have further relied upon First Horizon management, with the consent of IBKC, as to the reasonableness and achievability of the financial and operating forecasts and projections of First Horizon (with respect to fiscal years 2019 and 2020) and the estimates regarding certain pro forma financial effects of the Merger on First Horizon (including, without limitation, the cost savings and related expenses expected to result or be derived from the Merger), all as referred to above (and the assumptions and bases for all such information), and we have assumed that all such information has been reasonably prepared on a basis reflecting the best currently available estimates and judgments of First Horizon management and that the forecasts, projections and estimates reflected in such information will be realized in the amounts and in the time periods currently estimated by such management.

It is understood that the foregoing financial information of IBKC and First Horizon that was provided to us was not prepared with the expectation of public disclosure and that the foregoing financial information has been based on numerous variables and assumptions that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions) and, accordingly, actual results could vary significantly from those set forth in such information. We have assumed, based on discussions with the respective managements of IBKC and First Horizon and with the consent of the Board, that all such information provides a reasonable basis upon which we could form our opinion and we express no view as to any such information or the assumptions or bases therefor. We have relied on all such information without independent

verification or analysis and do not in any respect assume any responsibility or liability for the accuracy or completeness thereof.

We also assumed that there were no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either IBKC or First Horizon since the date of the last financial statements of each such entity that were made available to us. We are not experts in the independent verification of the adequacy of allowances for loan and lease losses and we have assumed, without independent verification and with your consent, that the aggregate allowances for loan and lease losses for IBKC and First Horizon are adequate to cover such losses. In rendering our opinion, we have not made or obtained any evaluations or appraisals or physical inspection of the property, assets or liabilities (contingent or otherwise) of IBKC or First Horizon, the collateral securing any of such assets or liabilities, or the collectability of any such assets, nor have we examined any individual loan or credit files, nor did we evaluate the solvency, financial capability or fair value of IBKC or First Horizon under any state or federal laws, including those relating to bankruptcy, insolvency or other matters. Estimates of values of companies and assets do not purport to be appraisals or necessarily reflect the prices at which companies or assets may actually be sold. Because such estimates are inherently subject to uncertainty, we assume no responsibility or liability for their accuracy.

We have assumed, in all respects material to our analyses, the following: (i) that the Merger and any related transactions (including, without limitation, the Bank Merger) will be completed substantially in accordance with the terms set forth in the Agreement (the final terms of which we have assumed will not differ in any respect material to our analyses from the draft reviewed by us and referred to above) with no adjustments to the Exchange Ratio and with no other consideration or payments in respect of IBKC Common Stock; (ii) that the representations and warranties of each party in the Agreement and in all related documents and instruments referred to in the Agreement are true and correct; (iii) that each party to the Agreement and all related documents will perform all of the covenants and agreements required to be performed by such party under such documents; (iv) that there are no factors that would delay or subject to any adverse conditions, any necessary regulatory or governmental approval for the Merger or any related transactions and that all conditions to the completion of the Merger and any related transaction will be satisfied without any waivers or modifications to the Agreement or any of the related documents; and (v) that in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the Merger and any related transaction, no restrictions, including any divestiture requirements, termination or other payments or amendments or modifications, will be imposed that will have a material adverse effect on the future results of operations or financial condition of IBKC, First Horizon or the pro forma entity, or the contemplated benefits of the Merger, including without limitation the cost savings and related expenses expected to result or be derived from the Merger. We have assumed that the Merger will be consummated in a manner that complies with the applicable provisions of the Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as amended, and all other applicable federal and state statutes, rules and regulations. We have further been advised by representatives of IBKC that IBKC has relied upon advice from its advisors (other than KBW) or other appropriate sources as to all legal, financial reporting, tax, accounting and regulatory matters with respect to IBKC, First Horizon, the Merger and any related transaction and the Agreement. KBW has not provided advice with respect to any such matters.

This opinion addresses only the fairness, from a financial point of view, as of the date hereof, of the Exchange Ratio in the Merger to the holders of IBKC Common Stock. We express no view or opinion as to any other terms or aspects of the Merger or any term or aspect of any related transaction, including without limitation, the form or structure of the Merger or any such related

transaction, any consequences of the Merger or any such related transaction to IBKC, its shareholders, creditors or otherwise, the treatment of IBKC’s outstanding preferred stock in the Merger, or any terms, aspects, merits or implications of any employment, consulting, voting, support, shareholder or other agreements, arrangements or understandings contemplated or entered into in connection with the Merger or otherwise. Our opinion is necessarily based upon conditions as they exist and can be evaluated on the date hereof and the information made available to us through the date hereof. It is understood that subsequent developments may affect the conclusion reached in this opinion and that KBW does not have an obligation to update, revise or reaffirm this opinion. Our opinion does not address, and we express no view or opinion with respect to, (i) the underlying business decision of IBKC to engage in the Merger or enter into the Agreement; (ii) the relative merits of the Merger as compared to any strategic alternatives that are, have been or may be available to or contemplated by IBKC or the Board; (iii) the fairness of the amount or nature of any compensation to any of IBKC’s officers, directors or employees, or any class of such persons, relative to the compensation to the holders of IBKC Common Stock; (iv) the effect of the Merger or any related transaction on, or the fairness of the consideration to be received by, holders of any class of securities of IBKC (other than the holders of IBKC Common Stock, solely with respect to the Exchange Ratio as described herein and not relative to the consideration to be received by holders of any other class of securities) or holders of any class of securities of First Horizon or any other party to any transaction contemplated by the Agreement; (v) the actual value of First Horizon Common Stock to be issued in the Merger; (vi) the prices, trading range or volume at which IBKC Common Stock or First Horizon Common Stock will trade following the public announcement of the Merger or the prices, trading range or volume at which First Horizon Common Stock will trade following the consummation of the Merger; (vii) any advice or opinions provided by any other advisor to any of the parties to the Merger or any other transaction contemplated by the Agreement; or (viii) any legal, regulatory, accounting, tax or similar matters relating to IBKC, First Horizon, their respective shareholders, or relating to or arising out of or as a consequence of the Merger or any related transaction (including the Bank Merger), including whether or not the Merger will qualify as a tax-free reorganization for United States federal income tax purposes.

This opinion is for the information of, and is directed to, the Board (in its capacity as such) in connection with its consideration of the financial terms of the Merger. This opinion does not constitute a recommendation to the Board as to how it should vote on the Merger, or to any holder of IBKC Common Stock or any shareholder of any other entity as to how to vote in connection with the Merger or any other matter, nor does it constitute a recommendation regarding whether or not any such shareholder should enter into a voting, shareholders’, or affiliates’ agreement with respect to the Merger or exercise any dissenters’ or appraisal rights that may be available to such shareholder.

This opinion has been reviewed and approved by our Fairness Opinion Committee in conformity with our policies and procedures established under the requirements of Rule 5150 of the Financial Industry Regulatory Authority.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio in the Merger is fair, from a financial point of view, to the holders of IBKC Common Stock.

Very truly yours,

Board of Directors
IBERIABANK Corporation
200 West Congress Street
Lafayette, LA 70501

Lady and Gentlemen:

You have requested our opinion as to the fairness from a financial point of view to the holders (other than First Horizon National Corporation (“First Horizon”) and its affiliates) of the outstanding shares of common stock, par value $1.00 per share (the “Shares”), of IBERIABANK Corporation (the “Company”) of the exchange ratio of 4.584 shares of common stock, par value $0.625 per share (the “First Horizon Common Stock”), of First Horizon to be paid for each Share (the “Exchange Ratio”), pursuant to the Agreement and Plan of Merger, dated as of November 3, 2019 (the “Agreement”), by and between First Horizon and the Company.

Goldman Sachs & Co. LLC and its affiliates are engaged in advisory, underwriting and financing, principal investing, sales and trading, research, investment management and other financial and non-financial activities and services for various persons and entities. Goldman Sachs & Co. LLC and its affiliates and employees, and funds or other entities they manage or in which they invest or have other economic interests or with which they co-invest, may at any time purchase, sell, hold or vote long or short positions and investments in securities, derivatives, loans, commodities, currencies, credit default swaps and other financial instruments of the Company, First Horizon, any of their respective affiliates and third parties, or any currency or commodity that may be involved in the transaction contemplated by the Agreement (the “Transaction”). We have acted as financial advisor to the Company in connection with, and have participated in certain of the negotiations leading to, the Transaction. We expect to receive fees for our services in connection with the Transaction, the principal portion of which is contingent upon consummation of the Transaction, and the Company has agreed to reimburse certain of our expenses arising, and indemnify us against certain liabilities that may arise, out of our engagement. We may in the future provide financial advisory and/or underwriting services to the Company, First Horizon and their respective affiliates for which our Investment Banking Division may receive compensation.

In connection with this opinion, we have reviewed, among other things, the Agreement; annual reports to stockholders and Annual Reports on Form 10-K of the Company and First Horizon for the five years ended December 31, 2018; certain interim reports to stockholders and Quarterly Reports on Form 10-Q of the Company and First Horizon; certain other communications from the Company and First Horizon to their respective stockholders; certain publicly available research analyst reports for the Company and First Horizon; certain internal financial analyses and forecasts for First Horizon on a stand-alone basis prepared by its management; certain internal financial analyses and forecasts for the Company on a stand-alone basis prepared by its management and certain financial analyses and forecasts for First Horizon on a stand-alone basis and pro-forma for the Transaction prepared by the management of the Company, in each case, as approved for our use by the Company (the “Forecasts”), including certain operating synergies projected by the management of the Company and the management of First Horizon to result from the Transaction, as approved for our use by the Company (the “Synergies”). We have also held discussions with members of the senior management of the Company and the senior management of First Horizon regarding their assessment of the strategic rationale for, and the potential benefits of, the Transaction and the past and current business operations, financial condition and future prospects of the Company and First Horizon; reviewed the reported price and trading activity for the Shares and shares of First Horizon Common Stock; compared certain financial and stock market information for the Company and First Horizon with similar information for certain other companies the securities

of which are publicly traded; reviewed the financial terms of certain recent business combinations in the banking industry; and performed such other studies and analyses, and considered such other factors, as we deemed appropriate.

For purposes of rendering this opinion, we have, with your consent, relied upon and assumed the accuracy and completeness of all of the financial, legal, regulatory, tax, accounting and other information provided to, discussed with or reviewed by, us, without assuming any responsibility for independent verification thereof. In that regard, we have assumed with your consent that the Forecasts, including the Synergies, have been reasonably prepared on a basis reflecting the best currently available estimates and judgments of the management of the Company. We have not reviewed individual credit files nor have we made an independent evaluation or appraisal of the assets and liabilities (including any contingent, derivative or other off-balance-sheet assets and liabilities) of the Company or First Horizon or any of their respective subsidiaries and we have not been furnished with any such evaluation or appraisal. We are not experts in the evaluation of loan and lease portfolios for purposes of assessing the adequacy of the allowances for losses with respect thereto and, accordingly, we have assumed that such allowances for the Company or First Horizon are in the aggregate adequate to cover such losses. We have assumed that all governmental, regulatory or other consents and approvals necessary for the consummation of the Transaction will be obtained without any adverse effect on the Company or First Horizon or on the expected benefits of the Transaction in any way meaningful to our analysis. We have assumed that the Transaction will be consummated on the terms set forth in the Agreement, without the waiver or modification of any term or condition the effect of which would be in any way meaningful to our analysis.

Our opinion does not address the underlying business decision of the Company to engage in the Transaction, or the relative merits of the Transaction as compared to any strategic alternatives that may be available to the Company; nor does it address any legal, regulatory, tax or accounting matters. This opinion addresses only the fairness from a financial point of view to the holders (other than First Horizon and its affiliates) of Shares as of the date hereof of the Exchange Ratio pursuant to the Agreement. We do not express any view on, and our opinion does not address, any other term or aspect of the Agreement or Transaction or any term or aspect of any other agreement or instrument contemplated by the Agreement or entered into or amended in connection with the Transaction, including, the fairness of the Transaction to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors, or other constituencies of the Company; nor as to the fairness of the amount or nature of any compensation to be paid or payable to any of the officers, directors or employees of the Company, or class of such persons, in connection with the Transaction, whether relative to the Exchange Ratio pursuant to the Agreement or otherwise. We are not expressing any opinion as to the prices at which shares of First Horizon Common Stock will trade at any time or as to the impact of the Transaction on the solvency or viability of the Company or First Horizon or the ability of the Company or First Horizon to pay their respective obligations when they come due. Our opinion is necessarily based on economic, monetary, market and other conditions as in effect on, and the information made available to us as of, the date hereof and we assume no responsibility for updating, revising or reaffirming this opinion based on circumstances, developments or events occurring after the date hereof. Our advisory services and the opinion expressed herein are provided for the information and assistance of the Board of Directors of the Company in connection with its consideration of the Transaction and such opinion does not constitute a recommendation as to how any holder of Shares should vote with respect to such Transaction or any other matter. This opinion has been approved by a fairness committee of Goldman Sachs & Co. LLC.

“Appraisal rights allow a shareholder to avoid the effects of the proposed corporate action described in this notice by selling the shareholder’s shares to the corporation at their fair value, paid in cash. To retain the right to assert appraisal rights, a shareholder is required by law not to sign any consent in favor of the proposed corporate action with respect to any shares of the class or series for which the shareholder intends to assert appraisal rights.

“Appraisal rights allow a shareholder to avoid the effects of the corporate action described in this notice by selling the shareholder’s shares to the corporation at their fair value, paid in cash. A shareholder may obtain appraisal rights only by completing and returning an appraisal form that the law requires the corporation to send to the shareholder, and by complying with all other requirements of Part 13 of the Business Corporation Act, a copy of which is enclosed.”

D. Where corporate action described in R.S. 12:1-1302(A) is proposed, or a merger pursuant to R.S. 12:1-1105 is effected, the notice referred to in Subsection A or C of this Section, if the corporation concludes that appraisal rights are or may be available, and in Subsection B of this Section shall be accompanied by both of the following:

E-5

E. The right to receive the information described in Subsection D of this Section may be waived in writing by a shareholder before or after the corporate action. If the information described in Subsection D of this Section is not publicly available, the shareholder who receives it owes a duty to the corporation to use and disclose the information only for purposes of deciding whether to exercise appraisal rights and for other proper purposes.

§ 12:1-1321 Notice of intent to demand appraisal and consequences of voting or consenting

If a corporate action specified in R.S. 12:1-1302(A) is to be approved by written consent, a shareholder may assert appraisal rights with respect to a class or series of shares only if the shareholder does not sign a consent in favor of the proposed action with respect to that class or series of shares.

C. A shareholder who fails to satisfy the requirements of Subsection A or B of this Section is not entitled to appraisal under this Part.

§ 12:1-1322 Appraisal notice and form

A. If a corporate action requiring appraisal rights under R.S. 12:1-1302(A) becomes effective, the corporation must send a written appraisal notice and the form required by Paragraph (B)(1) of this Section to all shareholders who satisfy the requirements of R.S. 12:1-1321(A) or R.S. 12:1-1321(B). In the case of a merger under R.S. 12:1-1105, the parent must deliver an appraisal notice and form to all record shareholders who may be entitled to assert appraisal rights.

B. The appraisal notice must be delivered no earlier than the date the corporate action specified in R.S. 12:1-1302(A) became effective, and no later than ten days after such date, and must do all of the following:

(1)

Supply a form that requires the shareholder asserting appraisal rights to certify that such shareholder did not vote for or consent to the transaction.

(2)

State all of the following:

(a)

Where the form must be sent and where certificates for certificated shares must be deposited and the date by which those certificates must be deposited, which date may not be earlier than the date for receiving the required form under Subparagraph (B)(2)(b) of this Section.

(b)

A date by which the corporation must receive the form, which date may not be fewer than forty nor more than sixty days after the date the appraisal notice is sent pursuant to Subsection A of this Section, and state that the shareholder shall have waived the right to demand appraisal with respect to the shares unless the form is received by the corporation by such specified date.

(c)

The corporation’s estimate of the fair value of the shares.

(d)

That, if requested in writing, the corporation will provide, to the shareholder so requesting, within ten days after the date specified in Subparagraph (B)(2)(b) of this Section the number of shareholders who return the forms by the specified date and the total number of shares owned by them.

E-6

(e)

The date by which the notice to withdraw under R.S. 12:1-1323 must be received, which date must be at least twenty days after the date specified in Subparagraph (B)(2)(b) of this Section.

(3)

Be accompanied by a copy of this Part.

C. A corporation may elect to withhold payment as permitted by R.S. 12:1-1325 only if the form required by Subsection B of this Section does both of the following:

(1)

Specifies the first date of any announcement to shareholders made prior to the date the corporate action became effective of the principal terms of the proposed corporate action.

(2)

If such announcement was made, requires the shareholder asserting appraisal rights to certify whether beneficial ownership of those shares for which appraisal rights are asserted was acquired before that date.

§ 12:1-1323 Perfection of rights and right to withdraw

A. A shareholder who receives notice pursuant to R.S. 12:1-1322 and who wishes to exercise appraisal rights must sign and return the form sent by the corporation and, in the case of certificated shares, deposit the shareholder’s certificates in accordance with the terms of the notice by the date referred to in the notice pursuant to R.S. 12:1-1322(B)(2)(b). In addition, if applicable, the shareholder must certify on the form whether the beneficial owner of such shares acquired beneficial ownership of the shares before the date required to be set forth in the notice pursuant to R.S. 12:1-1322(B)(1). If a shareholder fails to make this certification, the corporation may elect to treat the shareholder’s shares as after-acquired shares under R.S. 12:1-1325. Once a shareholder deposits that shareholder’s certificates or, in the case of uncertificated shares, returns the signed forms, that shareholder loses all rights as a shareholder, unless the shareholder withdraws pursuant to Subsection B of this Section.

B. A shareholder who has complied with Subsection A of this Section may nevertheless decline to exercise appraisal rights and withdraw from the appraisal process by so notifying the corporation in writing by the date set forth in the appraisal notice pursuant to R.S. 12:1-1322(B)(2)(e). A shareholder who fails to so withdraw from the appraisal process may not thereafter withdraw without the corporation’s written consent.

C. A shareholder who does not sign and return the form and, in the case of certificated shares, deposit that shareholder’s share certificates where required, each by the date set forth in the notice described in R.S. 12:1-1322(B), shall not be entitled to payment under this Part.

§ 12:1-1324 Payment

A. Except as provided in R.S. 12:1-1325, within thirty days after the form required by R.S. 12:1-1322(B)(2)(b) is due, the corporation shall pay in cash to those shareholders who complied with R.S. 12:1-1323(A) the amount the corporation estimates to be the fair value of their shares, plus interest.

B. Except as provided in Subsection C of this Section, the payment to each shareholder pursuant to Subsection A of this Section must be accompanied by all of the following:

(1)

(a) The annual financial statements specified in R.S. 12:1-1620(B) of the corporation that issued the shares to be appraised, which shall be of a date ending not more than sixteen months before the date of payment and shall comply with R.S. 12:1-1620(B); provided that, if such annual financial statements are not reasonably available, the corporation shall provide reasonably equivalent financial information.

(b) The latest available quarterly financial statements of such corporation, if any.

(2)

A statement of the corporation’s estimate of the fair value of the shares, which estimate must equal or exceed the corporation’s estimate given pursuant to R.S. 12:1-1322(B)(2)(c).

(3)

A statement that shareholders described in Subsection A of this Section have the right to demand further payment under R.S. 12:1-1326 and that if any such shareholder does not do so

E-7

within the time period specified therein, such shareholder shall be deemed to have accepted such payment in full satisfaction of the corporation’s obligations under this Part.

C. The financial information described in Paragraph (B)(1) of this Section need not accompany the corporation’s payment under Subsection A of this Section if the corporation has earlier delivered to the shareholder financial information that meets the requirements of Paragraph (B)(1) of this Section as of the time of the payment.

§ 12:1-1325 After-acquired shares

A. A corporation may elect to withhold payment required by R.S. 12:1-1324 from any shareholder who was required to, but did not, certify that beneficial ownership of all of the shareholder’s shares for which appraisal rights are asserted was acquired before the date specified in the appraisal notice sent in accordance with R.S. 12:1-1322(B)(1) and R.S. 12:1-1322(C).

B. If the corporation elects to withhold payment under Subsection A of this Section, it must, within thirty days after the form required by R.S. 12:1-1322(B)(2)(b) is due, notify all shareholders who are described in Subsection A of this Section of all of the following:

(1)

The information required by R.S. 12:1-1324(B)(1).

(2)

The corporation’s estimate of fair value pursuant to R.S. 12:1-1324(B)(2).

(3)

That they may accept the corporation’s estimate of fair value, plus interest, in full satisfaction of their demands or demand appraisal under R.S. 12:1-1326.

(4)

That those shareholders who wish to accept such offer must so notify the corporation of their acceptance of the corporation’s offer within thirty days after receiving the offer.

(5)

That those shareholders who do not satisfy the requirements for demanding appraisal under R.S. 12:1-1326 shall be deemed to have accepted the corporation’s offer.

C. Within ten days after receiving the shareholder’s acceptance pursuant to Subsection B of this Section, the corporation must pay in cash the amount it offered under Paragraph (B)(2) of this Section to each shareholder who agreed to accept the corporation’s offer in full satisfaction of the shareholder’s demand.

D. Within forty days after sending the notice described in Subsection B of this Section, the corporation must pay in cash the amount it offered to pay under Paragraph (B)(2) of this Section to each shareholder described in Paragraph (B)(5) of this Section.

§ 12:1-1326 Procedure if shareholder dissatisfied with payment or offer

A. A shareholder paid pursuant to R.S. 12:1-1324 who is dissatisfied with the amount of the payment must notify the corporation in writing of that shareholder’s estimate of the fair value of the shares and demand payment of that estimate plus interest, less any payment under R.S. 12:1-1324. A shareholder offered payment under R.S. 12:1-1325 who is dissatisfied with that offer must reject the offer and demand payment of the shareholder’s stated estimate of the fair value of the shares plus interest.

B. A shareholder who fails to notify the corporation in writing of that shareholder’s demand to be paid the shareholder’s stated estimate of the fair value plus interest under Subsection A of this Section within thirty days after receiving the corporation’s payment or offer of payment under R.S. 12:1-1324 or 1-1325, respectively, waives the right to demand payment under this Section and shall be entitled only to the payment made or offered pursuant to those respective Sections.

Subpart C. Judicial appraisal of shares

§ 12:1-1330 Court action

A. If a shareholder makes demand for payment under R.S. 12:1-1326 which remains unsettled, the corporation shall commence a summary proceeding within sixty days after receiving the payment

E-8

demand and petition the court to determine the fair value of the shares and accrued interest. If the corporation does not commence the proceeding within the sixty-day period, it shall pay in cash to each shareholder the amount the shareholder demanded pursuant to R.S. 12:1-1326, plus interest, within ten days after the expiration of the sixty-day period.

B. The corporation shall commence the proceeding in the district court of the parish where the corporation’s principal office or, if none, its registered office in this state is located. If the corporation is a foreign corporation without a registered office in this state, it shall commence the proceeding in the parish in this state where the principal office or registered office of the domestic corporation merged with the foreign corporation was located at the time of the transaction.

C. The corporation shall make all shareholders, whether or not residents of this state, whose demands remain unsettled parties to the proceeding, and all parties must be served with a copy of the petition. Nonresidents may be served as provided by law.

D. The jurisdiction of the court in which the proceeding is commenced under Subsection B of this Section is exclusive. The court may appoint an appraiser to file a written report with the court on the question of fair value. The appraiser shall have the powers described in the appointing order, or in any amendment to it. The shareholders demanding appraisal rights are entitled to the same discovery rights as parties in other civil proceedings. If the court appoints an appraiser, the appraiser’s written report shall be treated as the report of an expert witness, and the corporation and shareholders demanding appraisal shall be entitled to depose and to examine and cross-examine the appraiser as an expert witness.

E. Each shareholder made a party to the proceeding is entitled to judgment for either of the following:

(1)

The amount, if any, by which the court finds the fair value of the shareholder’s shares, plus interest, exceeds the amount paid by the corporation to the shareholder for such shares.

(2)

The fair value, plus interest, of the shareholder’s shares for which the corporation elected to withhold payment under R.S. 12:1-1325.

§ 12:1-1331 Court costs and expenses

A. The court in an appraisal proceeding commenced under R.S. 12:1-1330 shall determine all court costs of the proceeding, including the reasonable compensation and expenses of appraisers appointed by the court. The court shall assess the court costs against the corporation, except that the court may assess court costs against all or some of the shareholders demanding appraisal, in amounts which the court finds equitable, to the extent the court finds such shareholders acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by this Part.

B. The court in an appraisal proceeding may also assess the expenses of the respective parties in amounts the court finds equitable against either of the following:

(1)

The corporation and in favor of any or all shareholders demanding appraisal if the court finds the corporation did not substantially comply with the requirements of R.S. 12:1-1320, 1-1322, 1-1324, or 1-1325.

(2)

Either the corporation or a shareholder demanding appraisal, in favor of any other party, if the court finds the party against whom expenses are assessed acted arbitrarily, vexatiously, or not in good faith with respect to the rights provided by this Part.

C. If the court in an appraisal proceeding finds that the expenses incurred by any shareholder were of substantial benefit to other shareholders similarly situated and that such expenses should not be assessed against the corporation, the court may direct that such expenses be paid out of the amounts awarded the shareholders who were benefitted.

D. To the extent the corporation fails to make a required payment pursuant to R.S. 12:1-1324, 1-1325, 1-1326, or 1-1330(A), the shareholder may sue directly for the amount owed, and to the extent successful, shall be entitled to recover from the corporation all expenses of the suit. The

E-9

shareholder’s right to enforce the corporation’s payment obligation under this Subsection is perempted five years after the date that the payment by the corporation becomes due under the relevant provision.

Subpart D. Other remedies

§ 12:1-1340 Other remedies limited

A. The legality of a proposed or completed corporate action described in R.S. 12:1-1302(A) may not be contested, nor may the corporate action be enjoined, set aside or rescinded, in any proceeding commenced by a shareholder after the shareholders have approved the corporate action.

B. The appraisal rights provided by this Part are the exclusive remedy of a shareholder in connection with a corporate action for which R.S. 12:1-1302 makes appraisal rights available if either of the following conditions is satisfied:

(1)

The shareholder is not subject to the requirements of R.S. 12:1-1321(A)(1) concerning the delivery of a written notice of the shareholder’s intent to assert appraisal rights.

(2)

The corporation waives the requirements of R.S. 12:1-1321(A)(1).

C. If Subsection B of this Section makes appraisal rights the exclusive remedy of a shareholder, then the shareholder shall not have any other cause of action for damages or for any other form of relief against the corporation, or any director, officer, employee, agent, or controlling person of the corporation, in connection with the corporate action for which R.S. 12:1-1302 makes appraisal rights available.

D. If the corporation waives the requirements of R.S. 12:1-1321(A)(1), a shareholder may assert appraisal rights without complying with those requirements. A corporation waives the requirements of R.S. 12:1-1321(A)(1) by sending shareholders the notice specified in R.S. 12:1-1320(A)(2).

E. Subsections A, B, and C of this Section do not apply to a corporate action that is any of the following:

(1)

Not authorized and approved in accordance with the applicable provisions of any of the following:

(a)

Part 9, 10, 11, or 12 of this Chapter.

(b)

The articles of incorporation or bylaws.

(c)

The resolution of the board of directors authorizing the corporate action.

(2)

[Reserved.]

(3)

[Reserved.]

(4)

Approved by less than unanimous consent of the voting shareholders pursuant to R.S. 12:1-704 if both of the following requirements are met:

(a)

The challenge to the corporate action is brought by a shareholder who did not consent and as to whom notice of the approval of the corporate action was not effective at least ten days before the corporate action was effected.

(b)

The proceeding challenging the corporate action is commenced within ten days after notice of the approval of the corporate action is effective as to the shareholder bringing the proceeding.

F. Subsections B and C of this Section do not affect any right of a shareholder that is provided by the terms of the corporate action itself if the shareholder does not assert, or loses the right to enforce, appraisal rights under this Part.

FORM OF ARTICLES OF AMENDMENT
TO THE RESTATED CHARTER
OF FIRST HORIZON NATIONAL CORPORATION
(Rollover Preferred Stock Designation)

The undersigned, being a duly authorized officer of First Horizon National Corporation (the “Corporation”), acting pursuant to Sections 48-20-102 and 48-20-106 of the Tennessee Business Corporation Act, hereby certifies as follows:

1.

The name of the Corporation is FIRST HORIZON NATIONAL CORPORATION.

2.

The Restated Charter is hereby amended by adding the following text to Article X to set forth the terms of the Corporation’s Series B Non-Cumulative Perpetual Preferred Stock, Series C Non-Cumulative Perpetual Preferred Stock and Series D Non-Cumulative Perpetual Preferred Stock, by adding new sections (b), (c) and (d) to such Article X:

(b) 6.625% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series B. Pursuant to the provisions of the Restated Charter of the Corporation and applicable law, a series of preferred stock, no par value, of the Corporation be and hereby is created and the designation and number of shares of such series, and the voting and other powers, preferences and relative, participating, optional or other rights, and the qualifications, limitations and restrictions thereof, of the shares of such series, are as follows:

(1) Designation.

The designation of the series of preferred stock shall be “6.625% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series B” (the “Series B Preferred Stock”). With respect to payment of dividends and distributions upon the Corporation’s liquidation, dissolution or winding up, the Series B Preferred Stock shall rank (i) senior to the Corporation’s common stock and any other class or series of preferred stock that by its terms ranks junior to the Series B Preferred Stock, (ii) equally with all future series of preferred stock that the Corporation may issue that does not by its terms rank junior to the Series B Preferred Stock and (iii) junior to all existing and future indebtedness and other liabilities of the Corporation any class or series of preferred stock that expressly provides in the articles of amendment creating such preferred stock that it ranks senior to the Series B Preferred Stock (subject to any requisite consents required for the creation of such preferred stock ranking senior to the Series B Preferred Stock).

(2) Number of Shares.

The number of authorized shares of Series B Preferred Stock shall be 8,625. That number from time to time may be increased (but not in excess of the total number of authorized shares of preferred stock) or decreased (but not below the number of shares of Series B Preferred Stock then outstanding) by further resolution duly adopted by the Board of Directors (or a duly authorized committee thereof) and by the filing of a certificate pursuant to the provisions of Section 48-20-106 of the Tennessee Business Corporation Act stating that such increase or decrease, as the case may be, has been so authorized. The Corporation may from time to time, without notice to or the consent of holders of the Series B Preferred Stock, issue additional shares of Series B Preferred Stock, provided that if the additional shares are not fungible for U.S. federal income tax purposes with the initial shares of such series, the additional shares shall be issued under a separate CUSIP number. The additional shares would form a single series together with all previously issued shares of Series B Preferred Stock.

G-1

If no offered rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) on the relevant Dividend Determination Date at approximately 11:00 a.m., London time, then the calculation agent, in consultation with the Corporation, shall select four major banks in the London interbank market and shall request each of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time. If at least two quotations are provided, Three-month LIBOR shall be the arithmetic average (rounded upward if necessary to the nearest .00001 of 1%) of the quotations provided. Otherwise, the Calculation Agent in consultation with the Corporation shall select three major banks in New York City and shall request each of them to provide a quotation of the rate offered by it at approximately 11:00 a.m., New York City time, on the Dividend Determination Date for loans in U.S. dollars to leading European banks for a three month period for the applicable Dividend Period in an amount of at least $1,000,000.

Otherwise, Three-month LIBOR for the next Dividend Period shall be equal to Three-month LIBOR in effect for the then-current Dividend Period or, in the case of the first Dividend Period in the Floating Rate Period, the most recent rate on which Three-month LIBOR could have been determined in accordance with the first sentence of this Section had the dividend rate been a floating rate during the Fixed Rate Period.

(U) “Voting Parity Stock” shall have the meaning set forth in Section (7)(B) hereof.

(4) Dividends.

(A) Holders of the Series B Preferred Stock shall be entitled to receive, only when, as, and if declared by the Corporation’s Board of Directors (or a duly authorized committee thereof), out of assets legally available under applicable law for payment, non-cumulative cash dividends based on the Liquidation Preference, and no more, at a rate equal to (1) 6.625% per annum, for each semi-annual Dividend Period occurring from, and including, the original issue date of the Series B Preferred Stock to, but excluding, August 1, 2025 (the “Fixed Rate Period”), and (2) thereafter, Three-month LIBOR plus a spread of 426.2 basis points per annum (the “Spread”), for each quarterly Dividend Period beginning August 1, 2025 (the “Floating Rate Period”).

(B) When, as, and if declared by the Corporation’s Board of Directors (or a duly authorized committee thereof) (1) during the Fixed Rate Period, the Corporation shall pay cash dividends on the Series B Preferred Stock semi-annually, in arrears, on February 1 and August 1 of each year (each such date, a “Fixed Period Dividend Payment Date”), beginning on [•], and, when, as and if declared by the Corporation’s Board of Directors (or a duly authorized committee thereof) and (2) during the Floating Rate Period, the Corporation shall pay cash dividends on the Series B Preferred Stock quarterly, in arrears,

G-3

on February 1, May 1, August 1, and November 1 of each year, beginning on November 1, 2025 (each such date, a “Floating Period Dividend Payment Date,” and together with the Fixed Period Dividend Payment Dates, the “Dividend Payment Dates”). The Corporation shall pay cash dividends to the holders of record of shares of the Series B Preferred Stock as such holders appear on the Corporation’s stock register on the applicable record date, which shall be the fifteenth calendar day before that Dividend Payment Date or such other record date fixed by our Board of Directors (or a duly authorized committee thereof) that is not more than 60 nor less than 10 days prior to such Dividend Payment Date.

(C) If any Dividend Payment Date on or prior to August 1, 2025 is a day that is not a Business Day, then the dividend with respect to that Dividend Payment Date shall instead be paid on the immediately succeeding Business Day, without interest or other payment in respect of such delayed payment. If any Dividend Payment Date after August 1, 2025 is a day that is not a Business Day, then the Dividend Payment Date shall be the immediately succeeding Business Day unless such day falls in the next calendar month, in which case the Dividend Payment Date shall instead be the immediately preceding day that is a Business Day, and dividends will accumulate to the Dividend Payment Date as so adjusted.

(D) The Corporation shall calculate dividends on the Series B Preferred Stock for the Fixed Rate Period on the basis of a 360-day year of twelve 30-day months. The Corporation shall calculate dividends on the Series B Preferred Stock for the Floating Rate Period on the basis of the actual number of days in a Dividend Period and a 360-day year. Dollar amounts resulting from such calculation shall be rounded to the nearest cent, with one-half cent being rounded upward.

(E) Dividends on the Series B Preferred Stock shall not be cumulative or mandatory. If the Corporation’s Board of Directors (or a duly authorized committee thereof) does not declare a dividend on the Series B Preferred Stock for any Dividend Period prior to the related Dividend Payment Date, that dividend shall not accumulate, and the Corporation shall have no obligation to pay a dividend for that Dividend Period at any time, whether or not dividends on the Series B Preferred Stock or any other series of our preferred stock or common stock are declared for any future Dividend Period.

(F) Dividends on the Series B Preferred Stock shall accumulate from the original issue date of the Series B Preferred Stock at the then-applicable dividend rate on the liquidation preference amount of $10,000 per share. If the Corporation issues additional shares of the Series B Preferred Stock, dividends on those additional shares shall accumulate from the original issue date of those additional shares at the then-applicable dividend rate.

(G) The dividend rate for each Dividend Period in the Floating Rate Period shall be determined by the Calculation Agent using Three-month LIBOR as in effect on the second London Banking Day prior to the beginning of the Dividend Period, which date shall be the “Dividend Determination Date” for the relevant Dividend Period. The Calculation Agent then shall add Three-month LIBOR as determined on the Dividend Determination Date and the applicable Spread. Once the dividend rate for the Series B Preferred Stock is determined, the Calculation Agent shall deliver that information to the Corporation and the Transfer Agent. Absent manifest error, the Calculation Agent’s determination of the dividend rate for a Dividend Period for the Series B Preferred Stock shall be final.

(H) So long as any share of Series B Preferred Stock remains outstanding:

(i) no dividend shall be declared and paid or set aside for payment and no distribution shall be declared and made or set aside for payment on any Junior Stock (other than a dividend payable solely in shares of Junior Stock or any dividend in connection with the implementation of a stockholder rights plan or the redemption or repurchase of any rights under such a plan);

(ii) no shares of Junior Stock shall be repurchased, redeemed, or otherwise acquired for consideration by the Corporation, directly or indirectly (other than as a result of a

reclassification of Junior Stock for or into other Junior Stock, or the exchange for or conversion into Junior Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Junior Stock or pursuant to a contractually binding requirement to buy Junior Stock pursuant to a binding stock repurchase plan existing prior to the most recently completed Dividend Period), nor shall any monies be paid to or made available for a sinking fund for the redemption of any such securities by the Corporation; and

(iii) no shares of Parity Stock shall be repurchased, redeemed or otherwise acquired for consideration by the Corporation (other than pursuant to pro rata offers to purchase all, or a pro rata portion, of the Series B Preferred Stock and such Parity Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Parity Stock or Junior Stock, as a result of a reclassification of Parity Stock for or into other Parity Stock, or by conversion into or exchange for Junior Stock), during a Dividend Period, unless, in each case, the full dividends for the most recently completed Dividend Period on all outstanding shares of the Series B Preferred Stock have been declared and paid in full or declared and a sum sufficient for the payment of those dividends has been set aside. The foregoing limitations shall not apply to purchases or acquisitions of the Corporation’s Junior Stock pursuant to any employee or director incentive or benefit plan or arrangement (including any of the Corporation’s employment, severance, or consulting agreements) of the Corporation or of any of the Corporation’s subsidiaries heretofore or hereafter adopted.

(I) Except as provided below, for so long as any share of Series B Preferred Stock remains outstanding, the Corporation shall not declare, pay, or set aside for payment full dividends on any Parity Stock unless the Corporation has paid in full, or set aside payment in full, in respect of all accumulated dividends for all Dividend Periods for outstanding shares of Series B Preferred Stock. To the extent that the Corporation declares dividends on the Series B Preferred Stock and on any Parity Stock but cannot make full payment of such declared dividends, the Corporation shall allocate the dividend payments on a pro rata basis among the holders of the shares of Series B Preferred Stock and the holders of any Parity Stock then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, the Corporation shall allocate dividend payments based on the ratio between the then current and accumulated dividend payments due on the shares of Series B Preferred Stock and (1) in the case of cumulative Parity Stock the aggregate of the accumulated and unpaid dividends due on any such Parity Stock and (2) in the case of non-cumulative Parity Stock the aggregate of the declared but unpaid dividends due on any such Parity Stock. No interest shall be payable in respect of any dividend payment on Series B Preferred Stock that may be in arrears.

(J) Subject to the foregoing conditions, and not otherwise, dividends (payable in cash, stock, or otherwise), as may be determined by the Corporation’s Board of Directors (or a duly authorized committee thereof), may be declared and paid on the Corporation’s common stock and any Junior Stock from time to time out of any funds legally available for such payment, and the holders of the Series B Preferred Stock shall not be entitled to participate in such dividends.

(5) Liquidation Rights.

(A) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of the shares of Series B Preferred Stock then outstanding shall be entitled to be paid out of the Corporation’s assets legally available for distribution to the Corporation’s stockholders, before any distribution of assets is made to holders of common stock or any other Junior Stock, a liquidating distribution in the amount equal to the sum of (1) the Liquidation Preference, plus (2) the sum of any declared and unpaid dividends for prior Dividend Periods prior to the Dividend Period in which the liquidation distribution is made and any declared and unpaid dividends for the then current Dividend

G-5

Period in which the liquidation distribution is made to the date of such liquidation distribution. After payment of the full amount of the liquidating distributions to which they are entitled pursuant to the foregoing, the holders of Series B Preferred Stock shall have no right or claim to any remaining assets of the Corporation.

(B) In the event that, upon any such voluntary or involuntary liquidation, dissolution or winding up, the available assets of the Corporation are insufficient to pay the amount of the liquidating distributions on all outstanding shares of Series B Preferred Stock and the corresponding amounts payable on all shares of Parity Stock in the distribution of assets upon any liquidation, dissolution or winding up of the Corporation, then the holders of the Series B Preferred Stock and such Parity Stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they respectively would be entitled.

(C) For the purposes of this Section (5), the merger or consolidation of the Corporation with or into any other entity or by another entity with or into the Corporation or the sale, lease, exchange or other transfer of all or substantially all of the assets of the Corporation (for cash, securities or other consideration) shall not be deemed to constitute the liquidation, dissolution or winding up of the Corporation. If the Corporation enters into any merger or consolidation transaction with or into any other entity and the Corporation is not the surviving entity in such transaction, the Series B Preferred Stock may be converted into shares of the surviving or successor corporation or the direct or indirect parent of the surviving or successor corporation having terms identical to the terms of the Series B Preferred Stock set forth herein.

(6) Redemption Rights.

(A) Subject to the further terms and conditions provided herein, the Corporation may redeem the Series B Preferred Stock, in whole or in part, at its option, for cash, on any Dividend Payment Date on or after [•], with not less than 30 days’ and not more than 60 days’ notice (“Optional Redemption”), subject to the approval of the appropriate federal banking agency, at the redemption price provided in Section (6)(C) below. Dividends shall not accumulate on those shares of Series B Preferred Stock so redeemed on and after the applicable redemption date.

(B) In addition, the Corporation may, redeem the Series B Preferred Stock, in whole but not in part, at its option, for cash, at any time within 90 days following a Regulatory Capital Treatment Event, subject to the approval of the appropriate federal banking agency, at the redemption price provided in Section (6)(C) below (a “Regulatory Event Redemption”).

(C) The redemption price for any redemption of Series B Preferred Stock, whether an Optional Redemption or Regulatory Event Redemption, shall be equal to (i) $10,000 per share of Series B Preferred Stock, plus any declared and unpaid dividends (without regard to any undeclared dividends) to, but excluding, the date of redemption.

(D) Any notice given as provided in this Section (6) shall be conclusively presumed to have been duly given, whether or not the holder receives the notice, and any defect in the notice or in the provision of the notice, to any holder of shares of Series B Preferred Stock designated for redemption will not affect the redemption of any other shares of Series B Preferred Stock. Any notice provided to a holder of Series B Preferred Stock shall be deemed given on the date provided, whether or not the holder actually receives the notice. A notice of redemption shall be given not less than 30 days and not more than 60 days prior to the date of redemption specified in the notice, and shall specify (i) the redemption date, (ii) the redemption price, (iii) if fewer than all shares of Series B Preferred Stock are to be redeemed, the number of shares of Series B Preferred Stock to be redeemed and (iv) the manner in which holders of Series B Preferred Stock called for redemption may obtain payment of the redemption price in respect of those shares. Notwithstanding

G-6

anything to the contrary in this paragraph, if the Series B Preferred Stock is issued in book-entry form through The Depository Trust Company or any other similar facility, notice of redemption may be given to the holders of Series B Preferred Stock at such time and in any manner permitted by such facility.

(E) If notice of redemption of any shares of Series B Preferred Stock has been given by the Corporation and if the funds necessary for such redemption have been set aside by the Corporation in trust for the benefit of the holders of any shares of Series B Preferred Stock, then from and after the Redemption Date such shares of Series B Preferred Stock shall no longer be outstanding for any purpose, all dividends with respect to such shares of Series B Preferred Stock shall cease to accumulate from the Redemption Date and all rights of the holders of such shares shall terminate, except the right to receive the Redemption Price, without interest. Series B Preferred Stock redeemed pursuant to this Section (6) or purchased or otherwise acquired for value by the Corporation shall, after such acquisition, have the status of authorized and unissued shares of preferred stock and may be reissued by the Corporation at any time as shares of any series of preferred stock other than as Series B Preferred Stock.

(F) In the event that fewer than all the outstanding shares of Series B Preferred Stock are to be redeemed, the shares of Series B Preferred Stock to be redeemed shall be selected either pro rata or by lot or in such other manner as the Board of Directors of the Corporation (or a duly authorized committee thereof), determines to be fair and equitable, subject to the provisions hereof. The Board of Directors of the Corporation (or a duly authorized committee thereof) shall have the full power and authority to prescribe the terms and conditions upon which such shares of Series B Preferred Stock may be redeemed from time to time.

(G) No holder of Series B Preferred Stock shall have the right to require the redemption of the Series B Preferred Stock.

(7) Voting Rights.

(A) Holders of Series B Preferred Stock shall not have any voting rights, except as set forth below or as otherwise required by the Tennessee Business Corporation Act.

(B) Whenever dividends payable on the Series B Preferred Stock or any other class or series of preferred stock ranking equally with the Series B Preferred Stock as to payment of dividends, and upon which voting rights equivalent to those described in this paragraph have been conferred and are exercisable, have not been declared and paid in an aggregate amount equal to, as to any class or series, the equivalent of at least three or more semi-annual or six or more quarterly Dividend Periods, as applicable, whether or not for consecutive Dividend Periods (a “Nonpayment”), the holders of outstanding shares of the Series B Preferred Stock voting as a class with holders of shares of any other series of our preferred stock ranking equally with the Series B Preferred Stock as to payment of dividends, and upon which like voting rights have been conferred and are exercisable (“Voting Parity Stock”), shall be entitled to vote for the election of two additional directors of the Board of Directors of the Corporation on the terms set forth in this Section (7) (and to fill any vacancies in the terms of such directorships) (the “Preferred Stock Directors”). Holders of all series of our Voting Parity Stock shall vote as a single class. In the event that the holders of the shares of the Series B Preferred Stock are entitled to vote as described in this Section (7), the number of members of the Corporation’s Board of Directors at that time shall be increased by two directors, and the holders of the Series B Preferred Stock shall have the right, as members of that class, to elect two directors at a special meeting called at the request of the holders of record of at least 20% of the aggregate voting power of the Series B Preferred Stock or any other series of Voting Parity Stock (unless such request is received less than 90 days before the date fixed for the Corporation’s next annual or special meeting of the stockholders, in which event such election shall be held at such next annual or special meeting of the stockholders), provided

G-7

that the election of any Preferred Stock Directors shall not cause the Corporation to violate the corporate governance requirements of the New York Stock Exchange (or any other exchange on which the securities of the Corporation may at such time be listed) that listed companies must have a majority of independent directors, and provided further that at no time shall the Board of Directors of the Corporation include more than two Preferred Stock Directors.

(C) The Preferred Stock Directors elected at any such special meeting shall hold office until the next annual meeting of the Corporation’s stockholders unless they have been previously terminated or removed pursuant to Section (7)(D). In case any vacancy in the office of a Preferred Stock Director occurs (other than prior to the initial election of the Preferred Stock Directors), the vacancy may be filled by the written consent of the Preferred Stock Director remaining in office, or if none remains in office, by the vote of the holders of the Series B Preferred Stock (together with holders of any Voting Parity Stock) to serve until the next annual meeting of the stockholders.

(D) When the Corporation has paid full dividends on the Series B Preferred Stock for the equivalent of at least two semi-annual or four quarterly Dividend Periods, as applicable, following a Nonpayment, then the right of the holders of Series B Preferred Stock to elect the Preferred Stock Directors set forth in this Section (7) shall cease (except as provided by law and subject always to the same provisions for the vesting of the special voting rights in the case of any future Nonpayment). Upon termination of the right of the holders of the Series B Preferred Stock and Voting Parity Stock to vote for Preferred Stock Directors as set forth in this Section (7), the term of office of all Preferred Stock Directors then in office elected by only those holders shall terminate immediately. Whenever the term of office of the Preferred Stock Directors ends and the related voting rights have expired, the number of directors automatically will be decreased to the number of directors as otherwise would prevail. Any Preferred Stock Director may be removed at any time without cause by the holders of record of a majority of the outstanding shares of the Series B Preferred Stock (together with holders of any Voting Parity Stock) when they have the voting rights described in Section (7)(B).

(E) So long as any shares of Preferred Stock remain outstanding, the Corporation shall not, without the affirmative vote or consent of holders of at least 662/3% in voting power of the Series B Preferred Stock and any Voting Parity Stock, voting together as a single class, given in person or by proxy, either in writing without a meeting or at any meeting called for the purpose, authorize, create or issue any capital stock ranking senior to the Series B Preferred Stock as to dividends or the distribution of assets upon liquidation, dissolution or winding up, or reclassify any authorized capital stock into any such shares of such capital stock or issue any obligation or security convertible into or evidencing the right to purchase any such shares of capital stock. Further, so long as any shares of the Series B Preferred Stock remain outstanding, the Corporation shall not, without the affirmative vote of the holders of at least 662/3% in voting power of the Series B Preferred Stock, amend, alter or repeal any provision of these Articles of Amendment or the Restated Charter of the Corporation, including by merger, consolidation or otherwise, so as to adversely affect the powers, preferences or special rights of the Series B Preferred Stock.

Notwithstanding the foregoing, (i) any increase in the amount of authorized common stock or authorized preferred stock, or any increase or decrease in the number of shares of any series of preferred stock, or the authorization, creation and issuance of other classes or series of capital stock, in each case ranking on parity with or junior to the shares of the Series B Preferred Stock as to dividends and distribution of assets upon liquidation, dissolution or winding up, shall not be deemed to adversely affect such powers, preferences or special rights and (ii) a merger or consolidation of the Corporation with or into another entity in which the shares of the Series B Preferred Stock (A) remain outstanding or (B) are converted into or exchanged for preference securities of the surviving entity or any entity, directly or indirectly, controlling such surviving entity and such new preference

G-8

securities have powers, preferences and special rights that are not materially less favorable than the Series B Preferred Stock shall not be deemed to adversely affect the powers, preferences or special rights of the Series B Preferred Stock.

(F) Notice for a special meeting to elect the Preferred Stock Directors shall be given in a similar manner to that provided in the Corporation’s By-laws for a special meeting of the stockholders. If the secretary of the Corporation does not call a special meeting within 20 days after receipt of any such request, then any holder of Series B Preferred Stock may (at the Corporation’s expense) call such meeting, upon notice as provided in this Section (7)(F), and for that purpose shall have access to the stock register of the Corporation.

(G) Except as otherwise set forth in Section (7)(F) hereof, the rules and procedures for calling and conducting any meeting of the holders of Series B Preferred Stock (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules that the Board of Directors of the Corporation (or a duly authorized committee thereof), in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of the Restated Charter of the Corporation, the By-laws of the Corporation, and applicable laws and the rules of any national securities exchange or other trading facility on which Series B Preferred Stock is listed or traded at the time.

(8) Conversion Rights.

The holders of Series B Preferred Stock shall not have any rights to convert such shares into shares of any other class or series of stock or into any other securities of, or any interest or property in, the Corporation.

(9) No Sinking Fund.

No sinking fund shall be established for the retirement or redemption of Series B Preferred Stock.

(10) No Preemptive or Subscription Rights.

No holder of Series B Preferred Stock of the Corporation shall, as such holder, have any preemptive right to purchase or subscribe for any additional shares of stock of the Corporation or any other security of the Corporation that it may issue or sell.

(11) No Other Rights.

The Series B Preferred Stock shall not have any designations, preferences or relative, participating, optional or other special rights except as set forth herein or in the Restated Charter of the Corporation or as otherwise required by applicable law.

(c) 6.60% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series C. Pursuant to the provisions of the Restated Charter of the Corporation and applicable law, a series of preferred stock, no par value, of the Corporation be and hereby is created and the designation and number of shares of such series, and the voting and other powers, preferences and relative, participating, optional or other rights, and the qualifications, limitations and restrictions thereof, of the shares of such series, are as follows:

(1) Designation.

The designation of the series of preferred stock shall be “6.60% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series C” (the “Series C Preferred Stock”). With respect to payment of dividends and distributions upon the Corporation’s liquidation, dissolution or winding up, the Series C Preferred Stock shall rank (i) senior to the Corporation’s common stock and any other class or series of preferred stock that by its terms ranks junior to the Series C Preferred Stock, (ii) equally with all existing and future series of preferred stock that

G-9

does not by its terms so provide, including the Series B Preferred Stock and (iii) junior to all existing and future indebtedness and other liabilities of the Corporation any class or series of preferred stock that expressly provides in the articles of amendment creating such preferred stock that it ranks senior to the Series C Preferred Stock (subject to any requisite consents prior to issuance).

(2) Number of Shares.

The number of authorized shares of Series C Preferred Stock shall be 5,750. That number from time to time may be increased (but not in excess of the total number of authorized shares of preferred stock) or decreased (but not below the number of shares of Series C Preferred Stock then outstanding) by further resolution duly adopted by the Board of Directors (or a duly authorized committee thereof) and by the filing of a certificate pursuant to the provisions of Section 48-20-106 of the Tennessee Business Corporation Act stating that such increase or decrease, as the case may be, has been so authorized. The Corporation may from time to time, without notice to or the consent of holders of the Series C Preferred Stock, issue additional shares of Series C Preferred Stock, provided that if the additional shares are not fungible for U.S. federal income tax purposes with the initial shares of such series, the additional shares shall be issued under a separate CUSIP number. The additional shares would form a single series together with all previously issued shares of Series C Preferred Stock.

(S) “Voting Parity Stock” shall have the meaning set forth in Section (7)(B) hereof.

G-11

(4) Dividends.

(A) Holders of the Series C Preferred Stock shall be entitled to receive, only when, as, and if declared by the Corporation’s Board of Directors (or a duly authorized committee thereof), out of assets legally available under applicable law for payment, non-cumulative cash dividends based on the Liquidation Preference, and no more, at a rate equal to (1) 6.60% per annum, for each quarterly Dividend Period occurring from, and including, the original issue date of the Series C Preferred Stock to, but excluding, May 1, 2026 (the “Fixed Rate Period”), and (2) thereafter, Three-month LIBOR plus a spread of 492 basis points per annum (the “Spread”), for each quarterly Dividend Period beginning May 1, 2026 (the “Floating Rate Period”).

(B) When, as, and if declared by the Corporation’s Board of Directors (or a duly authorized committee thereof), the Corporation shall pay cash dividends on the Series C Preferred Stock quarterly, in arrears, on February 1, May 1, August 1, and November 1 of each year (each such date, a “Dividend Payment Date”), beginning on [•], and, when, as and if declared by the Corporation’s Board of Directors (or a duly authorized committee thereof). The Corporation shall pay cash dividends to the holders of record of shares of the Series C Preferred Stock as such holders appear on the Corporation’s stock register on the applicable record date, which shall be the fifteenth calendar day before that Dividend Payment Date or such other record date fixed by our Board of Directors (or a duly authorized committee thereof) that is not more than 60 nor less than 10 days prior to such Dividend Payment Date.

(C) If any Dividend Payment Date on or prior to May 1, 2026 is a day that is not a Business Day, then the dividend with respect to that Dividend Payment Date shall instead be paid on the immediately succeeding Business Day, without interest or other payment in respect of such delayed payment. If any Dividend Payment Date after May 1, 2026 is a day that is not a Business Day, then the Dividend Payment Date shall be the immediately succeeding Business Day unless such day falls in the next calendar month, in which case the Dividend Payment Date shall instead be the immediately preceding day that is a Business Day, and dividends will accumulate to the Dividend Payment Date as so adjusted.

(D) The Corporation shall calculate dividends on the Series C Preferred Stock for the Fixed Rate Period on the basis of a 360-day year of twelve 30-day months. The Corporation shall calculate dividends on the Series C Preferred Stock for the Floating Rate Period on the basis of the actual number of days in a Dividend Period and a 360-day year. Dollar amounts resulting from such calculation shall be rounded to the nearest cent, with one-half cent being rounded upward.

(E) Dividends on the Series C Preferred Stock shall not be cumulative or mandatory. If the Corporation’s Board of Directors (or a duly authorized committee thereof) does not declare a dividend on the Series C Preferred Stock for any Dividend Period prior to the related Dividend Payment Date, that dividend shall not accumulate, and the Corporation shall have no obligation to pay a dividend for that Dividend Period at any time, whether or not dividends on the Series C Preferred Stock or any other series of our preferred stock or common stock are declared for any future Dividend Period.

(F) Dividends on the Series C Preferred Stock shall accumulate from the original issue date of the Series C Preferred Stock at the then-applicable dividend rate on the liquidation preference amount of $10,000 per share. If the Corporation issues additional shares of the Series C Preferred Stock, dividends on those additional shares shall accumulate from the original issue date of those additional shares at the then-applicable dividend rate.

(G) The dividend rate for each Dividend Period in the Floating Rate Period shall be determined by the Calculation Agent using Three-month LIBOR as in effect on the second London Banking Day prior to the beginning of the Dividend Period, which date shall be the “Dividend Determination Date” for the relevant Dividend Period. The Calculation

G-12

Agent then shall add Three-month LIBOR as determined on the Dividend Determination Date and the applicable Spread. Once the dividend rate for the Series C Preferred Stock is determined, the Calculation Agent shall deliver that information to the Corporation and the Transfer Agent. Absent manifest error, the Calculation Agent’s determination of the dividend rate for a Dividend Period for the Series C Preferred Stock shall be final.

(H) So long as any share of Series C Preferred Stock remains outstanding:

(i) no dividend shall be declared and paid or set aside for payment and no distribution shall be declared and made or set aside for payment on any Junior Stock (other than a dividend payable solely in shares of Junior Stock or any dividend in connection with the implementation of a stockholder rights plan or the redemption or repurchase of any rights under such a plan);

(ii) no shares of Junior Stock shall be repurchased, redeemed, or otherwise acquired for consideration by the Corporation, directly or indirectly (other than as a result of a reclassification of Junior Stock for or into other Junior Stock, or the exchange for or conversion into Junior Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Junior Stock or pursuant to a contractually binding requirement to buy Junior Stock pursuant to a binding stock repurchase plan existing prior to the most recently completed Dividend Period), nor shall any monies be paid to or made available for a sinking fund for the redemption of any such securities by the Corporation; and

(iii) no shares of Parity Stock shall be repurchased, redeemed or otherwise acquired for consideration by the Corporation (other than pursuant to pro rata offers to purchase all, or a pro rata portion, of the Series C Preferred Stock and such Parity Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Parity Stock or Junior Stock, as a result of a reclassification of Parity Stock for or into other Parity Stock, or by conversion into or exchange for Junior Stock), during a Dividend Period, unless, in each case, the full dividends for the most recently completed Dividend Period on all outstanding shares of the Series C Preferred Stock have been declared and paid in full or declared and a sum sufficient for the payment of those dividends has been set aside. The foregoing limitations shall not apply to purchases or acquisitions of the Corporation’s Junior Stock pursuant to any employee or director incentive or benefit plan or arrangement (including any of the Corporation’s employment, severance, or consulting agreements) of the Corporation or of any of the Corporation’s subsidiaries heretofore or hereafter adopted.

(I) Except as provided below, for so long as any share of Series C Preferred Stock remains outstanding, the Corporation shall not declare, pay, or set aside for payment full dividends on any Parity Stock unless the Corporation has paid in full, or set aside payment in full, in respect of all accumulated dividends for all Dividend Periods for outstanding shares of Series C Preferred Stock. To the extent that the Corporation declares dividends on the Series C Preferred Stock and on any Parity Stock but cannot make full payment of such declared dividends, the Corporation shall allocate the dividend payments on a pro rata basis among the holders of the shares of Series C Preferred Stock and the holders of any Parity Stock then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, the Corporation shall allocate dividend payments based on the ratio between the then current and accumulated dividend payments due on the shares of Series C Preferred Stock and (1) in the case of cumulative Parity Stock the aggregate of the accumulated and unpaid dividends due on any such Parity Stock and (2) in the case of non-cumulative Parity Stock the aggregate of the declared but unpaid dividends due on any such Parity Stock. No interest shall be payable in respect of any dividend payment on Series C Preferred Stock that may be in arrears.

(J) Subject to the foregoing conditions, and not otherwise, dividends (payable in cash, stock, or otherwise), as may be determined by the Corporation’s Board of Directors (or a duly

G-13

authorized committee thereof), may be declared and paid on the Corporation’s common stock and any Junior Stock from time to time out of any funds legally available for such payment, and the holders of the Series C Preferred Stock shall not be entitled to participate in such dividends.

(5) Liquidation Rights.

(A) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of the shares of Series C Preferred Stock then outstanding shall be entitled to be paid out of the Corporation’s assets legally available for distribution to the Corporation’s stockholders, before any distribution of assets is made to holders of common stock or any other Junior Stock, a liquidating distribution in the amount equal to the sum of (1) the Liquidation Preference, plus (2) the sum of any declared and unpaid dividends for prior Dividend Periods prior to the Dividend Period in which the liquidation distribution is made and any declared and unpaid dividends for the then current Dividend Period in which the liquidation distribution is made to the date of such liquidation distribution. After payment of the full amount of the liquidating distributions to which they are entitled pursuant to the foregoing, the holders of Series C Preferred Stock shall have no right or claim to any remaining assets of the Corporation.

(B) In the event that, upon any such voluntary or involuntary liquidation, dissolution or winding up, the available assets of the Corporation are insufficient to pay the amount of the liquidating distributions on all outstanding shares of Series C Preferred Stock and the corresponding amounts payable on all shares of Parity Stock in the distribution of assets upon any liquidation, dissolution or winding up of the Corporation, then the holders of the Series C Preferred Stock and such Parity Stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they respectively would be entitled.

(C) For the purposes of this Section (5), the merger or consolidation of the Corporation with or into any other entity or by another entity with or into the Corporation or the sale, lease, exchange or other transfer of all or substantially all of the assets of the Corporation (for cash, securities or other consideration) shall not be deemed to constitute the liquidation, dissolution or winding up of the Corporation. If the Corporation enters into any merger or consolidation transaction with or into any other entity and the Corporation is not the surviving entity in such transaction, the Series C Preferred Stock may be converted into shares of the surviving or successor corporation or the direct or indirect parent of the surviving or successor corporation having terms identical to the terms of the Series C Preferred Stock set forth herein.

(6) Redemption Rights.

(A) Subject to the further terms and conditions provided herein, the Corporation may redeem the Series C Preferred Stock, in whole or in part, at its option, for cash, on any Dividend Payment Date on or after May 1, 2026, with not less than 30 days’ and not more than 60 days’ notice (“Optional Redemption”), subject to the approval of the appropriate federal banking agency, at the redemption price provided in Section (6)(C) below. Dividends shall not accumulate on those shares of Series C Preferred Stock so redeemed on and after the applicable redemption date.

(B) In addition, the Corporation may, redeem the Series C Preferred Stock, in whole but not in part, at its option, for cash, at any time within 90 days following a Regulatory Capital Treatment Event, subject to the approval of the appropriate federal banking agency, at the redemption price provided in Section (6)(C) below (a “Regulatory Event Redemption”).

(C) The redemption price for any redemption of Series C Preferred Stock, whether an Optional Redemption or Regulatory Event Redemption, shall be equal to (i)

G-14

$10,000 per share of Series C Preferred Stock, plus any declared and unpaid dividends (without regard to any undeclared dividends) to, but excluding, the date of redemption.

(D) Any notice given as provided in this Section (6) shall be conclusively presumed to have been duly given, whether or not the holder receives the notice, and any defect in the notice or in the provision of the notice, to any holder of shares of Series C Preferred Stock designated for redemption will not affect the redemption of any other shares of Series C Preferred Stock. Any notice provided to a holder of Series C Preferred Stock shall be deemed given on the date provided, whether or not the holder actually receives the notice. A notice of redemption shall be given not less than 30 days and not more than 60 days prior to the date of redemption specified in the notice, and shall specify (i) the redemption date, (ii) the redemption price, (iii) if fewer than all shares of Series C Preferred Stock are to be redeemed, the number of shares of Series C Preferred Stock to be redeemed and (iv) the manner in which holders of Series C Preferred Stock called for redemption may obtain payment of the redemption price in respect of those shares. Notwithstanding anything to the contrary in this paragraph, if the Series C Preferred Stock is issued in book-entry form through The Depository Trust Company or any other similar facility, notice of redemption may be given to the holders of Series C Preferred Stock at such time and in any manner permitted by such facility.

(E) If notice of redemption of any shares of Series C Preferred Stock has been given by the Corporation and if the funds necessary for such redemption have been set aside by the Corporation in trust for the benefit of the holders of any shares of Series C Preferred Stock, then from and after the Redemption Date such shares of Series C Preferred Stock shall no longer be outstanding for any purpose, all dividends with respect to such shares of Series C Preferred Stock shall cease to accumulate from the Redemption Date and all rights of the holders of such shares shall terminate, except the right to receive the Redemption Price, without interest. Series C Preferred Stock redeemed pursuant to this Section (6) or purchased or otherwise acquired for value by the Corporation shall, after such acquisition, have the status of authorized and unissued shares of preferred stock and may be reissued by the Corporation at any time as shares of any series of preferred stock other than as Series C Preferred Stock.

(F) In the event that fewer than all the outstanding shares of Series C Preferred Stock are to be redeemed, the shares of Series C Preferred Stock to be redeemed shall be selected either pro rata or by lot or in such other manner as the Board of Directors of the Corporation (or a duly authorized committee thereof), determines to be fair and equitable, subject to the provisions hereof. The Board of Directors of the Corporation (or a duly authorized committee thereof) shall have the full power and authority to prescribe the terms and conditions upon which such shares of Series C Preferred Stock may be redeemed from time to time.

(G) No holder of Series C Preferred Stock shall have the right to require the redemption of the Series C Preferred Stock.

(7) Voting Rights.

(A) Holders of Series C Preferred Stock shall not have any voting rights, except as set forth below or as otherwise required by the Tennessee Business Corporation Act.

(B) Whenever dividends payable on the Series C Preferred Stock or any other class or series of preferred stock ranking equally with the Series C Preferred Stock, including the Series B Preferred Stock, as to payment of dividends, and upon which voting rights equivalent to those described in this paragraph have been conferred and are exercisable, have not been declared and paid in an aggregate amount equal to, as to any class or series, the equivalent of at least six or more quarterly Dividend Periods, whether or not for consecutive Dividend Periods (a “Nonpayment”), the holders of outstanding shares of the Series C Preferred Stock voting as a class with holders of shares of any other series of our

G-15

preferred stock ranking equally with the Series C Preferred Stock, including the Series B Preferred Stock, as to payment of dividends, and upon which like voting rights have been conferred and are exercisable (“Voting Parity Stock”), shall be entitled to vote for the election of two additional directors of the Board of Directors of the Corporation on the terms set forth in this Section (7) (and to fill any vacancies in the terms of such directorships) (the “Preferred Stock Directors”). Holders of all series of our Voting Parity Stock shall vote as a single class. In the event that the holders of the shares of the Series C Preferred Stock are entitled to vote as described in this Section (7), the number of members of the Corporation’s Board of Directors at that time shall be increased by two directors, and the holders of the Series C Preferred Stock shall have the right, as members of that class, to elect two directors at a special meeting called at the request of the holders of record of at least 20% of the aggregate voting power of the Series C Preferred Stock or any other series of Voting Parity Stock (unless such request is received less than 90 days before the date fixed for the Corporation’s next annual or special meeting of the stockholders, in which event such election shall be held at such next annual or special meeting of the stockholders), provided that the election of any Preferred Stock Directors shall not cause the Corporation to violate the corporate governance requirements of the New York Stock Exchange (or any other exchange on which the securities of the Corporation may at such time be listed) that listed companies must have a majority of independent directors, and provided further that at no time shall the Board of Directors of the Corporation include more than two Preferred Stock Directors.

(C) The Preferred Stock Directors elected at any such special meeting shall hold office until the next annual meeting of the Corporation’s stockholders unless they have been previously terminated or removed pursuant to Section (7)(D). In case any vacancy in the office of a Preferred Stock Director occurs (other than prior to the initial election of the Preferred Stock Directors), the vacancy may be filled by the written consent of the Preferred Stock Director remaining in office, or if none remains in office, by the vote of the holders of the Series C Preferred Stock (together with holders of any Voting Parity Stock) to serve until the next annual meeting of the stockholders.

(D) When the Corporation has paid full dividends on the Series C Preferred Stock for the equivalent of at least four quarterly Dividend Periods, following a Nonpayment, then the right of the holders of Series C Preferred Stock to elect the Preferred Stock Directors set forth in this Section (7) shall cease (except as provided by law and subject always to the same provisions for the vesting of the special voting rights in the case of any future Nonpayment). Upon termination of the right of the holders of the Series C Preferred Stock and Voting Parity Stock to vote for Preferred Stock Directors as set forth in this Section (7), the term of office of all Preferred Stock Directors then in office elected by only those holders shall terminate immediately. Whenever the term of office of the Preferred Stock Directors ends and the related voting rights have expired, the number of directors automatically will be decreased to the number of directors as otherwise would prevail. Any Preferred Stock Director may be removed at any time without cause by the holders of record of a majority of the outstanding shares of the Series C Preferred Stock (together with holders of any Voting Parity Stock) when they have the voting rights described in Section (7)(B).

(E) So long as any shares of Preferred Stock remain outstanding, the Corporation shall not, without the affirmative vote or consent of holders of at least 66 2/3% in voting power of the Series C Preferred Stock and any Voting Parity Stock, voting together as a single class, given in person or by proxy, either in writing without a meeting or at any meeting called for the purpose, authorize, create or issue any capital stock ranking senior to the Series C Preferred Stock as to dividends or the distribution of assets upon liquidation, dissolution or winding up, or reclassify any authorized capital stock into any such shares of such capital stock or issue any obligation or security convertible into or evidencing the right to purchase any such shares of capital stock. Further, so long as any shares of the Series C Preferred

G-16

Stock remain outstanding, the Corporation shall not, without the affirmative vote of the holders of at least 66 2/3% in voting power of the Series C Preferred Stock, amend, alter or repeal any provision of these Articles of Amendment or the Restated Charter of the Corporation, including by merger, consolidation or otherwise, so as to affect the powers, preferences or special rights of the Series C Preferred Stock.

Notwithstanding the foregoing, (i) any increase in the amount of authorized common stock or authorized preferred stock, or any increase or decrease in the number of shares of any series of preferred stock, or the authorization, creation and issuance of other classes or series of capital stock, in each case ranking on parity with or junior to the shares of the Series C Preferred Stock as to dividends and distribution of assets upon liquidation, dissolution or winding up, shall not be deemed to affect such powers, preferences or special rights and (ii) a merger or consolidation of the Corporation with or into another entity in which the shares of the Series C Preferred Stock (A) remain outstanding or (B) are converted into or exchanged for preference securities of the surviving entity or any entity, directly or indirectly, controlling such surviving entity and such new preference securities have powers, preferences and special rights that are not materially less favorable than the Series C Preferred Stock shall not be deemed to affect the powers, preferences or special rights of the Series C Preferred Stock.

(F) Notice for a special meeting to elect the Preferred Stock Directors shall be given in a similar manner to that provided in the Corporation’s By-laws for a special meeting of the stockholders. If the secretary of the Corporation does not call a special meeting within 20 days after receipt of any such request, then any holder of Series C Preferred Stock may (at the Corporation’s expense) call such meeting, upon notice as provided in this Section (7)(F), and for that purpose shall have access to the stock register of the Corporation.

(G) Except as otherwise set forth in Section (7)(F) hereof, the rules and procedures for calling and conducting any meeting of the holders of Series C Preferred Stock (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules that the Board of Directors of the Corporation (or a duly authorized committee thereof), in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of the Restated Charter of the Corporation, the By-laws of the Corporation, and applicable laws and the rules of any national securities exchange or other trading facility on which Series C Preferred Stock is listed or traded at the time.

(8) Conversion Rights.

The holders of Series C Preferred Stock shall not have any rights to convert such shares into shares of any other class or series of stock or into any other securities of, or any interest or property in, the Corporation.

(9) No Sinking Fund.

No sinking fund shall be established for the retirement or redemption of Series C Preferred Stock.

(10) No Preemptive or Subscription Rights.

No holder of Series C Preferred Stock of the Corporation shall, as such holder, have any preemptive right to purchase or subscribe for any additional shares of stock of the Corporation or any other security of the Corporation that it may issue or sell.

G-17

(11) No Other Rights.

The Series C Preferred Stock shall not have any designations, preferences or relative, participating, optional or other special rights except as set forth herein or in the Company’s Restated Charter or as otherwise required by applicable law.

(d) 6.60% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series D. Pursuant to the provisions of the Restated Charter of the Corporation and applicable law, a series of preferred stock, no par value, of the Corporation be and hereby is created and the designation and number of shares of such series, and the voting and other powers, preferences and relative, participating, optional or other rights, and the qualifications, limitations and restrictions thereof, of the shares of such series, are as follows:

(1) Designation.

The designation of the series of preferred stock shall be “6.100% Fixed-to-Floating Non-Cumulative Perpetual Preferred Stock, Series D” (the “Series D Preferred Stock”). With respect to payment of dividends and distributions upon the Corporation’s liquidation, dissolution or winding up, the Series D Preferred Stock shall rank (i) senior to the Corporation’s common stock and any other class or series of capital stock that by its terms ranks junior to the Series D Preferred Stock, (ii) equally with all existing and future series of capital stock that does not by its terms so provide, including the Series B Preferred Stock and the Series C Preferred Stock and (iii) junior to all existing and future indebtedness and other liabilities of the Corporation any class or series of capital stock that expressly provides in the articles of amendment creating such preferred stock that it ranks senior to the Series D Preferred Stock (subject to any requisite consents prior to issuance).

(2) Number of Shares.

The number of authorized shares of Series D Preferred Stock shall be 10,000. That number from time to time may be increased (but not in excess of the total number of authorized shares of preferred stock) or decreased (but not below the number of shares of Series D Preferred Stock then outstanding) by further resolution duly adopted by the Board of Directors (or a duly authorized committee thereof) and by the filing of a certificate pursuant to the provisions of Section 48-20-106 of the Tennessee Business Corporation Act stating that such increase or decrease, as the case may be, has been so authorized. The Corporation may from time to time, without notice to or the consent of holders of the Series D Preferred Stock, issue additional shares of Series D Preferred Stock, provided that if the additional shares are not fungible for U.S. federal income tax purposes with the initial shares of such series, the additional shares shall be issued under a separate CUSIP number. The additional shares would form a single series together with all previously issued shares of Series D Preferred Stock.

(3) Definitions.

(Y) “Three-month LIBOR” shall mean, for each Dividend Determination Date related to the Floating-Rate Period, the rate determined by the Calculation Agent as follows:

(i) The London interbank offered rate for deposits in U.S. dollars for a three month period, as that rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) at approximately 11:00 a.m., London time, on the relevant Dividend Determination Date.

(ii) If no offered rate appears on Reuters screen page “LIBOR01” (or any successor or replacement page) on the relevant Dividend Determination Date at approximately 11:00 a.m., London time, then the Calculation Agent, in consultation with the Corporation, shall select four major banks in the London interbank market and shall request each of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars in amounts of at least $1,000,000 are offered by it to prime banks in the London interbank market, on that date and at that time. If at least two quotations are provided, Three-month LIBOR shall be the arithmetic average (rounded upward if necessary to the nearest .00001 of 1%) of the quotations provided. Otherwise, the Calculation Agent in consultation with the Corporation shall select three major banks in New York City and shall request each of them to provide a quotation of the rate offered by it at approximately 11:00 a.m., New York City time, on the Dividend Determination Date for loans in U.S. dollars to leading European banks for a three month period for the applicable Dividend Period in an amount of at least $1,000,000. If three quotations are provided, Three-month LIBOR shall be the arithmetic average of the quotations provided. Otherwise, if a LIBOR Event (as defined below) has not occurred, Three-month LIBOR for the next Dividend Period shall be equal to Three-month LIBOR in effect for the then-current Dividend Period or, in the case of the first Dividend Period in the Floating Rate Period, the most recent rate on which Three-month LIBOR could have been determined in accordance with the first sentence of this Section had the dividend rate been a floating rate during the Fixed Rate Period.

(iii) Notwithstanding clauses (1) and (2) above, if the Corporation, in its sole discretion, determines on the relevant Dividend Determination Date that the Three-month LIBOR has been permanently discontinued or is no longer viewed as an acceptable benchmark for securities like the Series D Preferred Stock, and the Corporation has notified the Calculation Agent (if it is not the Corporation) of such determination (a “LIBOR Event”), then the Calculation Agent will use, as directed by the Corporation, as a substitute or successor base rate (the “Alternative Rate”) for each future Dividend Determination Date, the alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution (including any committee or working group thereof) that is consistent with market practice regarding a substitute for the Three-month LIBOR. As part of such substitution, the Calculation Agent will, as directed by the Corporation, make such adjustment to the Alternative Rate or the spread thereon, as well as the business day convention, the Dividend Determination Date and related provisions and definitions (“Adjustments”), in each case that are consistent with market practice for the use of such Alternative Rate. Notwithstanding the foregoing, if the Calculation Agent determines that there is no alternative reference rate selected by the central bank, reserve bank, monetary authority or any similar institution

G-20

(including any committee or working group thereof) that is consistent with market practice regarding a substitute for Three-month LIBOR, the Corporation may, in its sole discretion, appoint an independent financial advisor (“IFA”) to determine an appropriate Alternative Rate and any Adjustments, and the decision of the IFA will be binding on the Corporation, the Calculation Agent and the holders of the Series D Preferred Stock. If on any Dividend Determination Date during the Floating-Rate Period (which may be the first Dividend Determination Date of the Floating-Rate Period) a LIBOR Event has occurred prior to such Dividend Determination Date and for any reason an Alternative Rate has not been determined or there is no such market practice for the use of such Alternative Rate (and, in each case, an IFA has not determined an appropriate Alternative Rate and Adjustments or an IFA has not been appointed) as of such Dividend Determination Date, then commencing on such Dividend Determination Date the dividend rate, Business Day convention and manner of calculating dividends applicable during the Fixed-Rate Period will be in effect for the applicable Dividend Period and will remain in effect during the remainder of the Floating-Rate Period. The establishment of Three-month LIBOR for each Dividend Period by the Calculation Agent (including, for the avoidance of doubt, at the direction of the Corporation in the case of clause (2)) or IFA, as applicable, shall (in the absence of manifest error) be final and binding. For the avoidance of doubt, any Adjustments made pursuant to clause (2) of the definition of “Three-month LIBOR” shall not be subject to the vote or consent of the holders of Series D Preferred Stock.

(Z) “Voting Parity Stock” shall have the meaning set forth in Section (7)(B) hereof.

(4) Dividends.

(A) Holders of the Series D Preferred Stock shall be entitled to receive, only when, as, and if declared by the Corporation’s Board of Directors (or a duly authorized committee thereof), out of assets legally available under applicable law for payment, non-cumulative cash dividends based on the Liquidation Preference, and no more, at a rate equal to (1) 6.100% per annum, for each semi-annual Dividend Period occurring from, and including, the original issue date of the Series D Preferred Stock to, but excluding, May 1, 2024 (the “Fixed Rate Period”), and (2) thereafter, Three-month LIBOR plus a spread of 385.9 basis points per annum (the “Spread”), for each quarterly Dividend Period beginning May 1, 2024 (the “Floating Rate Period”), subject to potential adjustment as provided in clause (3) of the definition of three-month LIBOR.

(B) When, as, and if declared by the Corporation’s Board of Directors (or a duly authorized committee thereof), the Corporation shall pay cash dividends on the Series D Preferred Stock (i) semi-annually, in arrears, on May 1 and November 1 of each year, beginning on [•] and ending on May 1, 2024, and (ii) quarterly, in arrears, on February 1, May 1, August 1, and November 1, beginning on August 1, 2024, subject to potential adjustment as provided in clause (3) of the definition of three-month LIBOR (each such date, a “Dividend Payment Date”). The Corporation shall pay cash dividends to the holders of record of shares of the Series D Preferred Stock as such holders appear on the Corporation’s stock register on the applicable record date, which shall be the fifteenth calendar day before that Dividend Payment Date or such other record date fixed by our Board of Directors (or a duly authorized committee thereof) that is not more than 60 nor less than 10 days prior to such Dividend Payment Date.

(C) If any Dividend Payment Date on or prior to May 1, 2024 is a day that is not a Business Day, then the dividend with respect to that Dividend Payment Date shall instead be paid on the immediately succeeding Business Day, without interest or other payment in respect of such delayed payment. If any Dividend Payment Date after May 1, 2024 is a day that is not a Business Day, then the Dividend Payment Date shall be the immediately succeeding Business Day unless such day falls in the next calendar month, in which case the

G-21

Dividend Payment Date shall instead be the immediately preceding day that is a Business Day, and dividends will accumulate to the Dividend Payment Date as so adjusted.

(D) The Corporation shall calculate dividends on the Series D Preferred Stock for the Fixed Rate Period on the basis of a 360-day year of twelve 30-day months. The Corporation shall calculate dividends on the Series D Preferred Stock for the Floating Rate Period on the basis of the actual number of days in a Dividend Period and a 360-day year, subject to potential adjustment as provided in clause (3) of the definition of three-month LIBOR. Dollar amounts resulting from such calculation shall be rounded to the nearest cent, with one-half cent being rounded upward.

(E) Dividends on the Series D Preferred Stock shall not be cumulative or mandatory. If the Corporation’s Board of Directors (or a duly authorized committee thereof) does not declare a dividend on the Series D Preferred Stock for any Dividend Period prior to the related Dividend Payment Date, that dividend shall not accumulate, and the Corporation shall have no obligation to pay a dividend for that Dividend Period at any time, whether or not dividends on the Series D Preferred Stock or any other series of our preferred stock or common stock are declared for any future Dividend Period,

(F) Dividends on the Series D Preferred Stock shall accumulate from the original issue date of the Series D Preferred Stock at the then-applicable dividend rate on the liquidation preference amount of $10,000 per share (equivalent to $25 per depositary share). If the Corporation issues additional shares of the Series D Preferred Stock, dividends on those additional shares shall accumulate from the original issue date of those additional shares at the then-applicable dividend rate.

(G) The dividend rate for each Dividend Period in the Floating Rate Period shall be determined by the Calculation Agent using Three-month LIBOR as in effect on the second London Banking Day prior to the beginning of the Dividend Period, which date shall be the “Dividend Determination Date” for the relevant Dividend Period. The Calculation Agent then shall add Three-month LIBOR as determined on the Dividend Determination Date and the applicable Spread. Once the dividend rate for the Series D Preferred Stock is determined, the Calculation Agent shall deliver that information to the Corporation and the Transfer Agent. Absent manifest error, the determination by the Calculation Agent (or, for the avoidance of doubt, by the IFA in the case of Section (3)(Y)(iii) above) of the dividend rate for a Dividend Period for the Series D Preferred Stock shall be final.

(H) During any Dividend Period, so long as any share of Series D Preferred Stock remains outstanding unless (i) the full dividends for the immediately preceding Dividend Period on all outstanding shares of Series D preferred stock have been paid in full or declared, and funds sufficient for the payment of those dividends set aside; and (ii) we are not in default on our obligation to redeem any shares of Series D preferred stock that have been called for redemption,

(i) no dividend shall be declared and paid or set aside for payment and no distribution shall be declared and made or set aside for payment on any Junior Stock (other than a dividend payable solely in shares of Junior Stock or any dividend in connection with the implementation of a shareholder rights plan or the redemption or repurchase of any rights under such a plan);

(ii) no shares of Junior Stock shall be repurchased, redeemed, or otherwise acquired for consideration by the Corporation, directly or indirectly (other than as a result of a reclassification of Junior Stock for or into other Junior Stock, or the exchange for or conversion into Junior Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Junior Stock or pursuant to a contractually binding requirement to buy Junior Stock pursuant to a binding stock repurchase plan existing prior to the most recently completed Dividend Period), nor shall any monies

G-22

be paid to or made available for a sinking fund for the redemption of any such securities by the Corporation; and

(iii) no shares of Parity Stock shall be repurchased, redeemed or otherwise acquired for consideration by the Corporation (other than pursuant to pro rata offers to purchase all, or a pro rata portion, of the Series D Preferred Stock and such Parity Stock, through the use of the proceeds of a substantially contemporaneous sale of other shares of Parity Stock or Junior Stock, as a result of a reclassification of Parity Stock for or into other Parity Stock, or by conversion into or exchange for Junior Stock), during a Dividend Period.

The foregoing limitations shall not apply to purchases or acquisitions of the Corporation’s Junior Stock pursuant to any employee or director incentive or benefit plan or arrangement (including any of the Corporation’s employment, severance, or consulting agreements) of the Corporation or of any of the Corporation’s subsidiaries heretofore or hereafter adopted.

(I) Except as provided below, for so long as any share of Series D Preferred Stock remains outstanding, the Corporation shall not declare, pay, or set aside for payment full dividends on any Parity Stock unless the Corporation has paid in full, or set aside funds sufficient for payment in full, in respect of all accumulated dividends for all Dividend Periods for outstanding shares of Series D Preferred Stock. To the extent that the Corporation declares dividends on the Series D Preferred Stock and on any Parity Stock but cannot make full payment of such declared dividends, the Corporation shall allocate the dividend payments on a pro rata basis among the holders of the shares of Series D Preferred Stock and the holders of any Parity Stock then outstanding. For purposes of calculating the pro rata allocation of partial dividend payments, the Corporation shall allocate dividend payments based on the ratio between the then current and accumulated dividend payments due on the shares of Series D Preferred Stock and (1) in the case of cumulative Parity Stock the aggregate of the accumulated and unpaid dividends due on any such Parity Stock and (2) in the case of non-cumulative Parity Stock the aggregate of the declared but unpaid dividends due on any such Parity Stock. No interest shall be payable in respect of any dividend payment on Series D Preferred Stock that may be in arrears.

(J) Subject to the foregoing conditions, and not otherwise, dividends (payable in cash, stock, or otherwise), as may be determined by the Corporation’s Board of Directors (or a duly authorized committee thereof), may be declared and paid on the Corporation’s common stock and any Junior Stock from time to time out of any funds legally available for such payment, and the holders of the Series D Preferred Stock shall not be entitled to participate in such dividends.

(5) Liquidation Rights.

(A) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of the shares of Series D Preferred Stock then outstanding shall be entitled to be paid out of the Corporation’s assets legally available for distribution to the Corporation’s shareholders, before any distribution of assets is made to holders of common stock or any other Junior Stock, a liquidating distribution in the amount equal to the sum of (1) the Liquidation Preference, plus (2) the sum of any declared and unpaid dividends for prior Dividend Periods prior to the Dividend Period in which the liquidation distribution is made and any declared and unpaid dividends for the then current Dividend Period in which the liquidation distribution is made to the date of such liquidation distribution. After payment of the full amount of the liquidating distributions to which they are entitled pursuant to the foregoing, the holders of Series D Preferred Stock shall have no right or claim to any remaining assets of the Corporation.

(B) In the event that, upon any such voluntary or involuntary liquidation, dissolution or winding up, the available assets of the Corporation are insufficient to pay the amount of the liquidating distributions on all outstanding shares of Series D Preferred Stock and the

G-23

corresponding amounts payable on all shares of Parity Stock in the distribution of assets upon any liquidation, dissolution or winding up of the Corporation, then the holders of the Series D Preferred Stock and such Parity Stock shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they respectively would be entitled.

(C) For the purposes of this Section (5), the merger or consolidation of the Corporation with or into any other entity or by another entity with or into the Corporation or the sale, lease, exchange or other transfer of all or substantially all of the assets of the Corporation (for cash, securities or other consideration) shall not be deemed to constitute the liquidation, dissolution or winding up of the Corporation. If the Corporation enters into any merger or consolidation transaction with or into any other entity and the Corporation is not the surviving entity in such transaction, the Series D Preferred Stock may be converted into or exchanged for preference securities of the surviving entity or any entity, directly or indirectly, controlling such surviving entity, so long as such new preference securities have powers, preferences and special rights that are identical to the powers, preferences and special rights of the Series D Preferred Stock set forth herein.

(6) Redemption Rights.

(A) Subject to the further terms and conditions provided herein, the Corporation may redeem the Series D Preferred Stock, in whole or in part, at its option, for cash, on any Dividend Payment Date on or after May 1, 2024, with not less than 30 days’ and not more than 60 days’ notice (“Optional Redemption”), subject to the approval of the appropriate federal banking agency, at the redemption price provided in Section (6)(C) below. Dividends shall not accumulate on those shares of Series D Preferred Stock so redeemed on and after the applicable redemption date.

(B) In addition, the Corporation may, redeem the Series D Preferred Stock, in whole but not in part, at its option, for cash, at any time within 90 days following a Regulatory Capital Treatment Event, subject to the approval of the appropriate federal banking agency, at the redemption price provided in Section (6)(C) below (a “Regulatory Event Redemption”).

(C) The redemption price for any redemption of Series D Preferred Stock, whether an Optional Redemption or Regulatory Event Redemption, shall be equal to (1) $10,000 per share of Series D Preferred Stock, plus any declared and unpaid dividends (without regard to any undeclared dividends) to, but excluding, the date of redemption.

(D) Any notice given as provided in this Section (6) shall be conclusively presumed to have been duly given, whether or not the holder receives the notice, and any defect in the notice or in the provision of the notice, to any holder of shares of Series D Preferred Stock designated for redemption will not affect the redemption of any other shares of Series D Preferred Stock. Any notice provided to a holder of Series D Preferred Stock shall be deemed given on the date provided, whether or not the holder actually receives the notice. A notice of redemption shall be given not less than 30 days and not more than 60 days prior to the date of redemption specified in the notice, and shall specify (i) the redemption date, (ii) the redemption price, (iii) if fewer than all shares of Series D Preferred Stock are to be redeemed, the number of shares of Series D Preferred Stock to be redeemed and (iv) the manner in which holders of Series D Preferred Stock called for redemption may obtain payment of the redemption price in respect of those shares. Notwithstanding anything to the contrary in this paragraph, if the Series D Preferred Stock is issued in book-entry form through The Depository Trust Company or any other similar facility, notice of redemption may be given to the holders of Series D Preferred Stock at such time and in any manner permitted by such facility.

(E) If notice of redemption of any shares of Series D Preferred Stock has been given by the Corporation and if the funds necessary for such redemption have been set aside by the

G-24

Corporation in trust for the benefit of the holders of any shares of Series D Preferred Stock, then from and after the Redemption Date such shares of Series D Preferred Stock shall no longer be outstanding for any purpose, all dividends with respect to such shares of Series D Preferred Stock shall cease to accumulate from the Redemption Date and all rights of the holders of such shares shall terminate, except the right to receive the Redemption Price, without interest. Series D Preferred Stock redeemed pursuant to this Section (6) or purchased or otherwise acquired for value by the Corporation shall, after such acquisition, have the status of authorized and unissued shares of preferred stock and may be reissued by the Corporation at any time as shares of any series of preferred stock other than as Series D Preferred Stock.

(F) In the event that fewer than all the outstanding shares of Series D Preferred Stock are to be redeemed, the shares of Series D Preferred Stock to be redeemed shall be selected either pro rata or by lot or in such other manner as the Board of Directors (or a duly authorized committee thereof), determines to be fair and equitable, subject to the provisions hereof. The Board of Directors (or a duly authorized committee thereof) shall have the full power and authority to prescribe the terms and conditions upon which such shares of Series D Preferred Stock may be redeemed from time to time.

(G) No holder of Series D Preferred Stock shall have the right to require the redemption of the Series D Preferred Stock.

(7) Voting Rights.

(A) Holders of Series D Preferred Stock shall not have any voting rights, except as set forth below or as otherwise required by the Tennessee Business Corporation Act.

(B) Whenever dividends payable on the Series D Preferred Stock or any other class or series of preferred stock ranking equally with the Series D Preferred Stock, including the Series B Preferred Stock and Series C Preferred Stock, as to payment of dividends, and upon which voting rights equivalent to those described in this paragraph have been conferred and are exercisable, have not been declared and paid in an aggregate amount equal to, as to any class or series, the equivalent of at least three Fixed Rate Periods or at least six Floating Rate Periods, as applicable, whether or not for consecutive Dividend Periods (a “Nonpayment”), the holders of outstanding shares of the Series D Preferred Stock voting as a class with holders of shares of any other series of our preferred stock ranking equally with the Series D Preferred Stock, including the Series B Preferred Stock and the Series C Preferred Stock, as to payment of dividends, and upon which like voting rights have been conferred and are exercisable (“Voting Parity Stock”), shall be entitled to vote for the election of two additional directors of the Board of Directors on the terms set forth in this Section (7) (and to fill any vacancies in the terms of such directorships) (the “Preferred Stock Directors”). Holders of all series of our Voting Parity Stock shall vote as a single class. In the event that the holders of the shares of the Series D Preferred Stock are entitled to vote as described in this Section (7), the number of members of the Corporation’s Board of Directors at that time shall be increased by two directors, and the holders of the Series D Preferred Stock shall have the right, as members of that class, to elect two directors at a special meeting called at the request of the holders of record of at least 20% of the aggregate voting power of the Series D Preferred Stock or any other series of Voting Parity Stock (unless such request is received less than 90 days before the date fixed for the Corporation’s next annual or special meeting of the shareholders, in which event such election shall be held at such next annual or special meeting of the shareholders), provided that the election of any Preferred Stock Directors shall not cause the Corporation to violate the corporate governance requirements of the New York Stock Exchange (or any other exchange on which the securities of the Corporation may at such time be listed) that listed companies must have a majority of independent directors, and provided further that at no time shall the Board of Directors include more than two Preferred Stock Directors.

G-25

(C) The Preferred Stock Directors elected at any such special meeting shall hold office until the next annual meeting of the Corporation’s shareholders unless they have been previously terminated or removed pursuant to Section (7)(D). In case any vacancy in the office of a Preferred Stock Director occurs (other than prior to the initial election of the Preferred Stock Directors), the vacancy may be filled by the written consent of the Preferred Stock Director remaining in office, or if none remains in office, by the vote of the holders of the Series D Preferred Stock (together with holders of any Voting Parity Stock) to serve until the next annual meeting of the shareholders.

(D) When the Corporation has paid full dividends on the Series D Preferred Stock for the equivalent of at least two Fixed Rate Periods or at least four Floating Rate Periods, as applicable, following a Nonpayment, then the right of the holders of Series D Preferred Stock to elect the Preferred Stock Directors set forth in this Section (7) shall cease (except as provided by law and subject always to the same provisions for the vesting of the special voting rights in the case of any future Nonpayment). Upon termination of the right of the holders of the Series D Preferred Stock and Voting Parity Stock to vote for Preferred Stock Directors as set forth in this Section (7), the term of office of all Preferred Stock Directors then in office elected by only those holders shall terminate immediately. Whenever the term of office of the Preferred Stock Directors ends and the related voting rights have expired, the number of directors automatically will be decreased to the number of directors as otherwise would prevail. Any Preferred Stock Director may be removed at any time without cause by the holders of record of a majority of the outstanding shares of the Series D Preferred Stock (together with holders of any Voting Parity Stock) when they have the voting rights described in Section (7)(B).

(E) So long as any shares of Preferred Stock remain outstanding, the Corporation shall not, without the affirmative vote or consent of holders of at least 66 2/3% in voting power of the Series D Preferred Stock and any Voting Parity Stock, voting together as a single class, given in person or by proxy, either in writing without a meeting or at any meeting called for the purpose, authorize, create or issue any capital stock ranking senior to the Series D Preferred Stock as to dividends or the distribution of assets upon liquidation, dissolution or winding up, or reclassify any authorized capital stock into any such shares of such capital stock or issue any obligation or security convertible into or evidencing the right to purchase any such shares of capital stock. Further, so long as any shares of the Series D Preferred Stock remain outstanding, the Corporation shall not, without the affirmative vote of the holders of at least 66 2/3% in voting power of the Series D Preferred Stock, amend, alter or repeal any provision of these Articles of Amendment or the Restated Charter of the Corporation, including by merger, consolidation or otherwise, so as to affect the powers, preferences or special rights of the Series D Preferred Stock. Notwithstanding the foregoing, (i) any increase in the amount of authorized common stock or authorized preferred stock, or any increase or decrease in the number of shares of any series of preferred stock, or the authorization, creation and issuance of other classes or series of capital stock, in each case ranking on parity with or junior to the shares of the Series D Preferred Stock as to dividends and distribution of assets upon liquidation, dissolution or winding up, shall not be deemed to affect such powers, preferences or special rights and (ii) a merger or consolidation of the Corporation with or into another entity in which the shares of the Series D Preferred Stock (A) remain outstanding or (B) are converted into or exchanged for preference securities of the surviving entity or any entity, directly or indirectly, controlling such surviving entity, so long as such new preference securities have powers, preferences and special rights that are identical to the powers, preferences and special rights of the Series D Preferred Stock set forth herein shall not be deemed to affect the powers, preferences or special rights of the Series D Preferred Stock.

(F) Notice for a special meeting to elect the Preferred Stock Directors shall be given in a similar manner to that provided in the Corporation’s By-laws for a special meeting of the shareholders. If the secretary of the Corporation does not call a special meeting within

G-26

20 days after receipt of any such request, then any holder of Series D Preferred Stock may (at the Corporation’s expense) call such meeting, upon notice as provided in this Section (7)(F), and for that purpose shall have access to the stock register of the Corporation.

(G) Except as otherwise set forth in Section (7)(F) hereof, the rules and procedures for calling and conducting any meeting of the holders of Series D Preferred Stock (including, without limitation, the fixing of a record date in connection therewith), the solicitation and use of proxies at such a meeting, the obtaining of written consents and any other aspect or matter with regard to such a meeting or such consents shall be governed by any rules that the Board of Directors of the Corporation (or a duly authorized committee thereof), in its discretion, may adopt from time to time, which rules and procedures shall conform to the requirements of the Restated Charter of the Corporation, the By-laws of the Corporation, and applicable laws and the rules of any national securities exchange or other trading facility on which Series D Preferred Stock is listed or traded at the time.

(8) Conversion Rights.

The holders of Series D Preferred Stock shall not have any rights to convert such shares into shares of any other class or series of stock or into any other securities of, or any interest or property in, the Corporation.

(9) No Sinking Fund.

No sinking fund shall be established for the retirement or redemption of Series D Preferred Stock.

(10) No Preemptive or Subscription Rights.

No holder of Series D Preferred Stock of the Corporation shall, as such holder, have any preemptive right to purchase or subscribe for any additional shares of stock of the Corporation or any other security of the Corporation that it may issue or sell.

(11) Information Rights.

During any period in which we are not subject to Section 13 or 15(d) of the Exchange Act and any shares of Series D preferred stock are outstanding, we will use commercially reasonable efforts to provide any requesting beneficial owner a copy of our most recently filed “Consolidated Financial Statements for Holding Companies-FR Y-9C” and “Consolidated Reports of Condition and Income for a Bank With Domestic Offices Only-FFIEC 041,” in each case or any applicable successor form.

(12) No Other Rights.

The Series D Preferred Stock shall not have any designations, preferences or relative, participating, optional or other special rights except as set forth herein or in the Corporation’s Restated Charter or as otherwise required by applicable law.

3.

The foregoing amendment to the Restated Charter was authorized by the Board of Directors (at a meeting duly convened and held on [ ] [ ], 2020) without shareholder action, as such was not required.

4.

The foregoing amendments will be effective upon filing of the Articles of Amendment with the Secretary of State of the State of Tennessee.

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers

Sections 48-18-501 through 48-18-509 of the TBCA authorize a corporation to provide for the indemnification of officers, directors, employees and agents in terms sufficiently broad to permit indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act. First Horizon adopted the provisions of the Tennessee statute pursuant to Article Six of First Horizon’s bylaws. In addition, First Horizon have a directors’ and officers’ liability insurance policy which provides coverage sufficiently broad to permit indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act.

Section 48-12-102 of the TBCA permits the inclusion in the charter of a Tennessee corporation of a provision, with certain exceptions, eliminating the personal monetary liability of directors to the corporation or its shareholders for breach of the duty of care. First Horizon has adopted the provisions of the statute as Article 14 of its charter.

First Horizon’s shareholders have approved a provision in Article Six of First Horizon’s bylaws pursuant to which First Horizon is required to indemnify each director and any officers designated by the board of directors, and advance expenses, to the maximum extent not prohibited by law. In accordance with the foregoing, First Horizon is authorized to enter into individual indemnity agreements with its directors and such officers. Such indemnity agreements have been approved for all of the directors and certain officers.

Certain rules of the Federal Deposit Insurance Corporation limit the ability of certain depository institutions, their subsidiaries and their affiliated depository institution holding companies to indemnify affiliated parties, including institution directors. In general, subject to the ability to purchase directors’ and officers’ liability insurance and to advance professional expenses under certain circumstances, the rules prohibit such institutions from indemnifying a director for certain costs incurred with regard to an administrative or enforcement action commenced by any federal banking agency that results in a final order or settlement pursuant to which the director is assessed a civil money penalty, removed from office, prohibited from participating in the affairs of an insured depository institution or required to cease and desist from or take an affirmative action described in Section 8(b) of the Federal Deposit Insurance Act (12 U.S.C. § 1818(b)).

Item 22. Undertakings

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) to include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) to reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement; notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) to include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of securities, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser: (i) any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424; (ii) any free writing prospectus relating to the offering prepared by

II-3

or on behalf of the undersigned registrant or used or referred to by the undersigned registrant; (iii) the portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and (iv) any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

(5) That, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(6) That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other items of the applicable form.

(7) That every prospectus (i) that is filed pursuant to paragraph (5) immediately preceding, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act of 1933 and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(8) To respond to requests for information that is incorporated by reference into this prospectus pursuant to Items 4, 10(b), 11, or 13 of this form, within one (1) business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means; this includes information contained in documents filed subsequent to the effective date of this registration statement through the date of responding to the request.

(9) To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in this registration statement when it became effective.

(10) Insofar as indemnification for liabilities under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable. In the event a claim of indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in a successful defense of any action, suit or proceeding) is asserted by such director, officer, or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
