PRELIMINARY JOINT PROXY STATEMENT/PROSPECTUS—SUBJECT TO COMPLETION—DATED MARCH 24, 2023

WASHINGTON FEDERAL, INC.

425 Pike Street

Seattle, Washington 98101

To the Shareholders of Washington Federal, Inc.:

On November 13, 2022, Washington Federal, Inc., a Washington corporation (“Washington Federal”), entered into an agreement and plan of reorganization (the “merger agreement”) to acquire Luther Burbank Corporation, a California corporation (“Luther Burbank”). If the required shareholder and regulatory approvals are obtained, all closing conditions are satisfied or waived and the merger is subsequently completed, Luther Burbank will be merged with and into Washington Federal, with Washington Federal as the surviving institution (the “merger”). Shortly thereafter, Luther Burbank’s wholly-owned bank subsidiary, Luther Burbank Savings, a California-chartered bank (“LB Savings”), will be merged with and into Washington Federal Bank, dba WaFd Bank, a Washington state chartered commercial bank and the wholly-owned bank subsidiary of Washington Federal (“WaFd Bank”), with WaFd Bank as the surviving bank.

You are cordially invited to attend a special meeting of Washington Federal shareholders, to be held virtually on Thursday, May 4, 2023 at 9:00 a.m., Pacific Time, (the “Washington Federal special meeting”). To attend the special meeting online please visit https://www.virtualshareholdermeeting.com/WAFD2023SM. At the Washington Federal special meeting, Washington Federal shareholders will be asked to consider and vote upon a proposal to approve the issuance of shares of Washington Federal common stock, par value $1.00 per share (the “Washington Federal common stock”) to the shareholders of Luther Burbank pursuant to the merger agreement (the “Washington Federal share issuance proposal”) and a proposal to adjourn the Washington Federal special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Washington Federal special meeting to approve the Washington Federal share issuance proposal. Luther Burbank will also hold a special meeting of shareholders to consider a proposal to approve the proposed merger agreement and the merger and a proposal to approve on a non-binding, advisory basis the compensation that certain named executive officers of Luther Burbank may receive that is based on or otherwise relates to the merger. Washington Federal and Luther Burbank cannot complete the proposed merger unless Washington Federal’s shareholders vote to approve the issuance of shares of Washington Federal common stock in connection with the merger and Luther Burbank’s shareholders vote to approve the merger agreement and the merger. This letter is accompanied by the attached joint proxy statement/prospectus, which Washington Federal’s board of directors (the “Washington Federal board”) is providing to you to solicit your vote for the approval of the Washington Federal share issuance proposal and the approval of the adjournment of the Washington Federal special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Washington Federal special meeting to approve the Washington Federal share issuance proposal. We refer to this solicitation as the Washington Federal proxy solicitation.

If the required shareholder and regulatory approvals are obtained and the merger is subsequently completed, upon effectiveness of the merger, each outstanding share of Luther Burbank common stock, no par value per share (“Luther Burbank common stock”), will be converted into, and canceled in exchange for, the right to receive 0.3353 shares of Washington Federal common stock (the “exchange ratio”). Cash will be paid in lieu of any fractional share interest. We refer to the aggregate consideration to be paid to Luther Burbank shareholders in the merger as the merger consideration.

##### Table of Contents

The implied value of the merger consideration to be paid to Luther Burbank is based on the exchange ratio of 0.3353 of a share of Washington Federal common stock for each share of Luther Burbank common stock. The implied value per share of Luther Burbank common stock on March 23, 2023, was approximately $9.71, which amount was based on the $28.97 closing price per share of Washington Federal common stock on that date. Based on the current number of shares of Luther Burbank common stock outstanding and the Luther Burbank restricted stock and Luther Burbank restricted stock units described in “The Merger Agreement — Consideration to be Received in the Merger,” Washington Federal expects to issue approximately 17,135,074 shares of Washington Federal common stock in the aggregate upon completion of the merger.

The value of the merger consideration will fluctuate based on the market price of Washington Federal common stock. Consequently, the value of the merger consideration will not be known at the time you vote on the merger agreement. Washington Federal’s common stock is listed on the NASDAQ Global Select Market under the symbol “WAFD.” You should obtain current market quotations for the Washington Federal common stock. Luther Burbank’s common stock is traded on the NASDAQ Global Select Market under the symbol “LBC.” You should obtain current market quotations for the Luther Burbank common stock.

Based on the reasons for the merger described in the accompanying document, the Washington Federal board has determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are in the best interests of Washington Federal and its shareholders. Accordingly, our board of directors has unanimously recommended that you vote “FOR” the proposal to approve the issuance of Washington Federal common stock to the shareholders of Luther Burbank pursuant to the merger agreement and “FOR” the proposal to approve the adjournment of the Washington Federal special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Washington Federal special meeting to approve the Washington Federal share issuance proposal. The accompanying joint proxy statement/prospectus describes the Washington Federal special meeting, the merger agreement and related matters. In addition to being a proxy statement of Washington Federal, this document also is the proxy statement for the solicitation of proxies from Luther Burbank shareholders to vote to approve the proposed merger agreement and to approve on a non-binding, advisory basis the compensation that certain named executive officers of Luther Burbank may receive that is based on or otherwise relates to the merger.

We encourage you to read this entire document carefully, including the considerations discussed under “Risk Factors” beginning on page 25, and the appendices to the accompanying joint proxy statement/prospectus, which include the merger agreement.

Your vote is very important. The merger cannot be completed unless the holders of a majority of the outstanding shares of Washington Federal common stock entitled to vote at the Washington Federal special meeting vote in favor of the Washington Federal share issuance proposal. Whether or not you plan to attend the Washington Federal special meeting, please take the time to vote by completing and mailing the enclosed proxy card or by following the instructions to vote via the Internet or by telephone indicated on the proxy card.

We appreciate your continuing loyalty and support and, should you choose to attend, we look forward to seeing you at the Washington Federal special meeting.

You are cordially invited to attend a special meeting of Luther Burbank shareholders (the “Luther Burbank special meeting”), to be held at 9:00 a.m., Pacific Time, on Thursday, May 4, 2023 at Luther Burbank’s corporate headquarters located at 520 Third Street, 4th Floor, Santa Rosa, California 95401.

Washington Federal will also hold a special meeting of shareholders to consider the issuance of shares of Washington Federal common stock, par value $1.00 per share (“Washington Federal common stock”), in connection with the merger. Washington Federal and Luther Burbank cannot complete the proposed merger unless Washington Federal’s shareholders vote to approve the issuance of shares of Washington Federal common stock in connection with the merger and Luther Burbank’s shareholders vote to approve the merger agreement and the merger. This letter is accompanied by the attached joint proxy statement/prospectus, which Luther Burbank’s board of directors (the “Luther Burbank board”) is providing to you to solicit your vote for the approval of the merger agreement and the merger, the approval, on a non-binding, advisory basis of the compensation that certain named executive officers of Luther Burbank may receive that is based on or otherwise relates to the merger and the approval of the adjournment of the Luther Burbank special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Luther Burbank special meeting to approve the Luther Burbank merger proposal. We refer to this solicitation as the Luther Burbank proxy solicitation.

If the required shareholder and regulatory approvals are obtained and the merger is subsequently completed, upon effectiveness of the merger, each outstanding share of Luther Burbank common stock, no par value per share (“Luther Burbank common stock”), will be converted into, and canceled in exchange for, the right to receive 0.3353 shares of Washington Federal common stock (the “exchange ratio”).

agreement. Based on the current number of shares of Luther Burbank common stock outstanding and the Luther Burbank restricted stock and Luther Burbank restricted stock units described in “The Merger Agreement — Consideration to be Received in the Merger,” Washington Federal expects to issue approximately 17,135,074 shares of Washington Federal common stock in the aggregate upon completion of the merger.

Luther Burbank’s common stock is traded on the NASDAQ Global Select Market under the symbol “LBC.” You should obtain current market quotations for the Luther Burbank common stock.

We expect the merger will qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended. Accordingly, Luther Burbank shareholders generally will not recognize any income, gain or loss for U.S. federal income tax purposes on the exchange of shares of Luther Burbank common stock for Washington Federal common stock in the corporate merger, except with respect to any cash received by Luther Burbank shareholders (i) in lieu of fractional shares of Luther Burbank common stock or (ii) on account of any accrued dividends or dividend equivalents payable to certain directors and employees of Luther Burbank and its subsidiaries.

Based on the reasons for the merger described in the accompanying document, the Luther Burbank board has determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are in the best interests of Luther Burbank and its shareholders. Accordingly, our board of directors has unanimously recommended that you vote “FOR” the proposal to approve the merger agreement and the merger, “FOR” the proposal to approve on a non-binding, advisory basis the compensation that certain named executive officers of Luther Burbank may receive that is based on or otherwise relates to the merger and “FOR” the proposal to approve the adjournment of the Luther Burbank special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Luther Burbank special meeting to approve the Luther Burbank merger proposal. The accompanying joint proxy statement/prospectus describes the Luther Burbank special meeting, the merger agreement and related matters. In addition to being a proxy statement of Luther Burbank, this document also is the proxy statement for the solicitation of proxies from Washington Federal shareholders to vote to approve the issuance of shares of Washington Federal common stock in connection with the merger and is the prospectus of Washington Federal for the shares of its common stock that will be issued to the Luther Burbank shareholders in connection with the merger.

We encourage you to read this entire document carefully, including the considerations discussed under “Risk Factors” beginning on page 25, and the appendices to the accompanying joint proxy statement/prospectus, which include the merger agreement.

QUESTIONS AND ANSWERS ABOUT THE MERGER AND THE SPECIAL MEETINGS

The following are some of the questions that you, as a shareholder of Washington Federal or Luther Burbank, may have regarding the merger, and the special meetings of Washington Federal and Luther Burbank, and brief answers to those questions. These questions and answers, as well as the following summary, are not meant to be a substitute for the information contained in the remainder of this document, and this information is qualified in its entirety by the more detailed descriptions and explanations contained elsewhere in this document. We urge you to read this document in its entirety because the information in this section does not provide all of the information that may be important to you with respect to the merger and the special meetings of Washington Federal and Luther Burbank. Additional important information is also contained in the documents incorporated by reference into this joint proxy statement/prospectus. See the section entitled “Where You Can Find More Information” beginning on page 151.

Q1: | Why am I receiving this joint proxy statement/prospectus?

A1: | You are receiving this joint proxy statement/prospectus because Washington Federal, Inc. (“Washington Federal”) and Luther Burbank Corporation (“Luther Burbank”) have entered into an agreement and plan of reorganization, dated as of November 13, 2022 (the “merger agreement”), pursuant to which, and subject to the terms and conditions therein, Luther Burbank will merge with and into Washington Federal, with Washington Federal as the surviving institution (the “merger”). Promptly following the completion of the merger, Luther Burbank Savings (“LB Savings”) will merge with and into Washington Federal Bank, doing business as WaFd Bank (“WaFd Bank”), with WaFd Bank as the surviving bank (the “bank merger”).

A copy of the merger agreement is attached as Appendix A to this document. In this joint proxy statement/prospectus, we refer to the closing of the merger as the “closing” and the date on which the closing occurs as the “closing date.”

In order to complete the merger, among other things:

| • |  | Luther Burbank shareholders must approve (such approval, the “requisite Luther Burbank shareholder approval”) the merger agreement and the merger (the “Luther Burbank merger proposal”); and

| • |  | Washington Federal shareholders must approve (such approval, the “requisite Washington Federal shareholder approval”) a proposal to approve the issuance of shares of Washington Federal common stock, par value $1.00 per share (the “Washington Federal common stock”), that will comprise the merger consideration pursuant to the merger agreement (the “Washington Federal share issuance proposal”).

In addition, Washington Federal shareholders will also be asked to approve a proposal to adjourn the special meeting of Washington Federal shareholders (the “Washington Federal special meeting”), if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the Washington Federal special meeting to approve the Washington Federal share issuance proposal (the “Washington Federal adjournment proposal”).

Luther Burbank shareholders will also be asked (i) to approve, on a non-binding, advisory basis, the compensation that certain named executive officers of Luther Burbank may receive that is based on or otherwise relates to the merger (the “Luther Burbank compensation proposal”), and (ii) to approve a proposal to adjourn the special meeting of Luther Burbank shareholders (the “Luther Burbank special meeting”), if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the Luther Burbank special meeting to approve the Luther Burbank merger proposal (the “Luther Burbank adjournment proposal”).

This document is also a prospectus that is being delivered to Luther Burbank shareholders because, pursuant to the merger agreement, Washington Federal is offering shares of Washington Federal common stock to Luther Burbank shareholders.

##### Table of Contents

This joint proxy statement/prospectus contains important information about the merger and the other proposals being voted on at the Washington Federal and Luther Burbank special meetings, and about the special meetings themselves. 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 special meeting. Your vote is important and we encourage you to submit your proxy as soon as possible.

Q2: | Will Luther Burbank shareholders be able to trade the Washington Federal common stock that they receive in the merger?

A2: | Yes. The Washington Federal common stock to be issued in the merger to Luther Burbank shareholders will be listed on the NASDAQ Global Select Market (the “NASDAQ”) under the symbol “WAFD.” Unless you are deemed an “affiliate” of Washington Federal after the merger is completed, you may sell the shares of Washington Federal common stock you receive in the merger without restriction.

Q3: | What is the vote required to approve each proposal?

A3: | Washington Federal Proposal 1—The Washington Federal Share Issuance Proposal. Approval of the Washington Federal share issuance proposal requires the affirmative vote, virtually or by proxy, of the majority of the votes cast at the Washington Federal special meeting. If you fail to submit a proxy or vote at the Washington Federal special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee with respect to the share issuance proposal, it will have no effect on such proposal.

Washington Federal Proposal 2—The Washington Federal Adjournment Proposal. Approval of the Washington Federal adjournment proposal requires the affirmative vote, virtually or by proxy, of the majority of the votes cast at the Washington Federal special meeting. If you fail to submit a proxy or vote at the Washington Federal meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee with respect to the share issuance proposal, it will have no effect on such proposal.

Luther Burbank Proposal 1—The Luther Burbank Merger Proposal. Approval of the Luther Burbank merger proposal requires the affirmative vote of the holders of a majority of the outstanding shares of Luther Burbank common stock, no par value per share (“Luther Burbank common stock”), entitled to vote at the Luther Burbank special meeting. If you fail to submit a proxy or to vote in person at the Luther Burbank special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the Luther Burbank merger proposal, it will have the same effect as a vote “AGAINST” the Luther Burbank merger proposal.

Luther Burbank Proposal 2—The Luther Burbank Compensation Proposal. Approval of the Luther Burbank compensation proposal requires the affirmative vote of a majority of shares of Luther Burbank common stock entitled to vote represented in person or by proxy and voting at the Luther Burbank special meeting (assuming a quorum is present). If you fail to submit a proxy or vote in person at the Luther Burbank special meeting, or fail to instruct your bank, broker or other nominee with respect to the compensation proposal, it will have no effect on such proposal (assuming a quorum is present). If you mark “ABSTAIN” on your proxy with respect to the compensation proposal, it will have the same effect as a vote “AGAINST” the Luther Burbank compensation proposal.

The Luther Burbank compensation proposal is advisory, and therefore not binding on Luther Burbank, the Luther Burbank board of director’s compensation committee or the Luther Burbank board of directors (the “Luther Burbank board”). Further, the arrangements are contractual in nature and not, by their terms, subject to Luther Burbank shareholder approval. Accordingly, regardless of the outcome of the Luther Burbank compensation proposal, if the merger is completed, Luther Burbank’s named executive officers may be or become entitled to receive the compensation that is based on or otherwise relates to the merger in accordance with the terms and conditions applicable to those payments.

Luther Burbank Proposal 3—The Luther Burbank Adjournment Proposal. Approval of the Luther Burbank adjournment proposal requires the affirmative vote of a majority of shares of Luther Burbank

common stock entitled to vote represented in person or by proxy and voting at the Luther Burbank special meeting. If you fail to submit a proxy or vote in person at the Luther Burbank special meeting, or fail to instruct your bank, broker or other nominee with respect to the Luther Burbank adjournment proposal, it will have no effect on such proposal. If you mark “ABSTAIN” on your proxy with respect to the Luther Burbank adjournment proposal, it will have the same effect as a vote “AGAINST” the Luther Burbank adjournment proposal.

Q4: | What will Luther Burbank shareholders receive in the merger?

A4: | Luther Burbank shareholders will receive, in exchange for each share of Luther Burbank common stock they hold (subject to certain exceptions set forth in the merger agreement), 0.3353 shares of Washington Federal common stock (the “merger consideration”), as further described in “The Merger Agreement — Consideration to be Received in the Merger” beginning on page 103. Washington Federal will not issue any fractional shares of Washington Federal common stock in the merger. Instead, Luther Burbank shareholders who would otherwise be entitled to a fractional share of Washington Federal common stock in the merger will instead receive an amount in cash (rounded to the nearest whole cent) determined by multiplying the average closing price per share of Washington Federal common stock, as reported on the NASDAQ, for the 20 trading days ending on and including the fifth trading day prior to the closing date (the “Washington Federal average share price”) by the fraction of a share (after taking into account all certificates representing Luther Burbank common stock and shares of Luther Burbank common stock held in book-entry form delivered by such shareholders) of Washington Federal common stock that such Luther Burbank shareholder would otherwise be entitled to receive.

Q5: | What will Washington Federal shareholders receive in the merger?

A5: | Washington Federal shareholders will not receive any consideration in the merger, and their shares of Washington Federal common stock will remain outstanding and will constitute shares of the combined company following the merger. Following the merger, shares of Washington Federal common stock will continue to be traded on the NASDAQ.

Q6: | Will the value of the merger consideration change between the date of this joint proxy statement/prospectus and the time the merger is completed?

A6: | Yes. Although the number of shares of Washington Federal common stock that Luther Burbank shareholders will receive is fixed, the value of the merger consideration will fluctuate between the date of this joint proxy statement/prospectus and the effective time of the merger based upon the market value of shares of Washington Federal common stock. Any fluctuation in the market price of Washington Federal common stock after the date of this joint proxy statement/prospectus will change the value of the shares of Washington Federal common stock that Luther Burbank shareholders will receive. Neither Washington Federal nor Luther Burbank is permitted to terminate the merger agreement as a result of any increase or decrease in the market price of Washington Federal common stock or Luther Burbank common stock.

Q7: | Why is my vote important?

A7: | The merger cannot be completed unless the Washington Federal shareholders approve the Washington Federal share issuance proposal and the Luther Burbank shareholders approve the Luther Burbank merger proposal, which are the only applicable Washington Federal and Luther Burbank shareholder proposals necessary to complete the merger. Information about the Washington Federal special meeting and the Luther Burbank special meeting, the merger, and other matters to be considered by shareholders of each of Washington Federal and Luther Burbank is contained in this document.

Each director and certain executive officers of Luther Burbank who beneficially own shares of Luther Burbank common stock, reflecting an aggregate of approximately 23.19% of the outstanding Luther Burbank common stock as of the close of business on March 23, 2023, the record date for the Luther Burbank special meeting (the “Luther Burbank record date”), entered into a shareholder agreement with Luther Burbank and Washington Federal (collectively, the “shareholder agreements”) pursuant to which

3

##### Table of Contents

he or she agreed, among other things, to vote all shares of Luther Burbank common stock beneficially owned by him or her in favor of adoption and approval of the merger, the merger agreement and the transactions contemplated by the merger agreement at any meeting of the shareholders of Luther Burbank, subject to certain conditions set forth therein.

Q8: | Why must the Washington Federal shareholders approve the issuance of shares of Washington Federal common stock in connection with the merger (i.e. the Washington Federal share issuance proposal)?

A8: | The Washington Federal shareholders are required to approve the issuance of shares of Washington Federal common stock in connection with the merger, which is estimated to equate to approximately 21% of Washington Federal’s issued and outstanding shares of common stock following the completion of the merger, because Washington Federal is listed on the NASDAQ and is subject to the NASDAQ listing rules. Because Washington Federal will issue in excess of 20% of its outstanding shares of common stock to the Luther Burbank shareholders in connection with the merger, under the NASDAQ listing rules, the shareholders of Washington Federal are required to approve the issuance of shares of Washington Federal common stock in connection with the merger. The merger cannot be completed unless the Washington Federal shareholders approve the Washington Federal share issuance proposal.

Q9: | Why am I being asked to consider and vote on a proposal to approve on a non-binding, advisory basis, the compensation that certain named executive officers of Luther Burbank may receive that is based on or otherwise relates to the merger (i.e. the Luther Burbank compensation proposal)?

A9: | Under Securities and Exchange Commission (the “SEC”) rules, Luther Burbank is required to seek a non-binding, advisory vote with respect to the compensation that may be paid or become payable to Luther Burbank’s named executive officers that is based on or otherwise relates to the merger, or “golden parachute” compensation.

Q10: | What happens if Luther Burbank shareholders do not approve, by a non-binding, advisory vote, the Luther Burbank compensation proposal?

A10: | The vote on the proposal to approve the Luther Burbank compensation proposal is separate and apart from the votes to approve the other proposals being presented at the Luther Burbank special meeting. Because the vote on the proposal to approve the merger-related executive compensation is advisory in nature only, it will not be binding upon Luther Burbank or Washington Federal. Accordingly, the merger-related compensation will be paid to Luther Burbank’s named executive officers to the extent payable in accordance with the terms of their compensation agreements and other contractual arrangements even if Luther Burbank shareholders do not approve the proposal to approve the merger-related executive compensation.

Q11: | What are the recommendations of the boards of directors of Washington Federal and Luther Burbank?

A11: | The Washington Federal board of directors (the “Washington Federal board”) had determined that the merger is in the best interests of Washington Federal and its shareholders and unanimously recommends a vote “FOR” approval of the Washington Federal share issuance proposal and “FOR” approval of the Washington Federal adjournment proposal.

See the section entitled “The Merger — Recommendation of the Washington Federal Board and Reasons of Washington Federal for the Merger” beginning on page 56 for a more detailed discussion of the Washington Federal board’s recommendation and reasons therefor.

The Luther Burbank board has determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are in the best interests of Luther Burbank and its shareholders

##### Table of Contents

and unanimously recommends a vote “FOR” approval of the Luther Burbank merger proposal, “FOR” approval of the Luther Burbank compensation proposal and “FOR” approval of the Luther Burbank adjournment proposal.

See the section entitled “The Merger — Recommendation of the Luther Burbank Board and Reasons of Luther Burbank for the Merger” beginning on page 73 for a more detailed discussion of the Luther Burbank board’s recommendations and reasons therefor. In addition, certain of Luther Burbank’s officers and directors have financial interests in the transactions contemplated by the merger agreement that are different from, or in addition to, the interests of Luther Burbank’s shareholders. These interests are described in more detail in the section entitled “The Merger — Interests of Certain Luther Burbank Officers and Directors in the Merger” beginning on page 91.

Q12: | Do I have dissenters’ or appraisal rights with respect to the merger?

A12: | No. The holders of Luther Burbank common stock do not have the right to dissent from the merger and assert dissenters’ or appraisal rights.

Under the California General Corporation Law, (the “CGCL”) shareholders are generally entitled to dissent from a merger or consolidation and obtain payment of the fair value of their shares when a merger or consolidation occurs. However, the CGCL provides that appraisal rights are not available for shares that are listed on a national securities exchange where the merger consideration is stock of a publicly-traded corporation. Luther Burbank’s common stock is traded on a national security exchange and the merger consideration, comprised of Washington Federal’s common stock, is also traded on a national securities exchange. As such, Luther Burbank’s shareholders are not entitled to appraisal rights.

Q13: | Are there any risks that should be considered in deciding whether to vote for the matters required to be voted on by the respective shareholders of Washington Federal and Luther Burbank?

A13: | Yes. Set forth under the section entitled “Risk Factors,” beginning on page 25, are a number of risk factors that each of the shareholders of Washington Federal and Luther Burbank should consider carefully.

Q14: | When do you expect to complete the merger?

A14: | We are working to complete the merger as early as the quarter ending September 30, 2023. We must first obtain the necessary regulatory approvals, the requisite Washington Federal shareholder approval and the requisite Luther Burbank shareholder approval, and other conditions to the consummation of the merger must be satisfied. In the event of delays, the date for completing the merger can occur as late as November 30, 2023 (which may be extended to February 29, 2024 by either Washington Federal or Luther Burbank by written notice to the other party if all regulatory approvals have not been obtained but all other conditions to closing have been satisfied or waived (other than conditions that by their nature are to be satisfied at the closing and are capable of being satisfied by such date)), after which Luther Burbank and Washington Federal would need to mutually agree to extend the closing date of the merger. We cannot assure you as to if and when all the conditions to the merger will be met nor can we predict the exact timing. It is possible we will not complete the merger.

Q15: | If the merger is completed, when can Luther Burbank shareholders expect to receive the merger consideration?

A15: | Promptly following completion of the merger, Washington Federal will mail to each former Luther Burbank shareholder of record written instructions detailing how its shareholders of record can exchange their shares of Luther Burbank common stock for shares of Washington Federal common stock.

Q16: | How will my rights as a Luther Burbank shareholder differ following the merger?

A16: | Following the closing of the merger, shareholders of Luther Burbank will receive shares of Washington Federal common stock in exchange for their shares of Luther Burbank common stock and become shareholders of Washington Federal, and their rights as shareholders of Washington Federal will be

5

##### Table of Contents

| governed by Washington Federal’s restated articles of incorporation, as amended (the “Washington Federal articles”), and Washington Federal’s amended and restated bylaws (the “Washington Federal bylaws”). The rights associated with Luther Burbank common stock are different from the rights associated with Washington Federal common stock. See the section entitled “Comparison of the Rights of Shareholders” beginning on page 137.

Q17: | What happens if the merger is not completed?

A17: | If the merger is not completed, holders of Luther Burbank common stock will not receive any consideration for their shares of Luther Burbank common stock in connection with the merger. Instead, Luther Burbank will remain an independent public company and its common stock will continue to be listed and traded on the NASDAQ. In addition, if the merger agreement is terminated in certain circumstances, Luther Burbank may be required to pay a termination fee. See the sections entitled “The Merger Agreement — Termination of the Merger Agreement” beginning on page 118 and “The Merger Agreement — Termination Fee” beginning on page 119 for a complete discussion of the circumstances under which a termination fee will be required to be paid.

Q18: | What are the material U.S. federal income tax consequences of the merger to me?

A18: | The merger is intended to qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended (the “Code”), for U.S. federal income tax purposes, and it is a condition to our respective obligations to complete the merger that each of Washington Federal and Luther Burbank receives a legal opinion to the effect that the merger will so qualify. Accordingly, assuming that the merger so qualifies as a reorganization, Luther Burbank shareholders generally will not recognize any income, gain or loss for U.S. federal income tax purposes on the exchange of Luther Burbank common stock for Washington Federal common stock in the merger, except for any gain or loss that may result from the receipt of cash (i) in lieu of a fractional share of Washington Federal common stock or (ii) on account of accrued dividends or dividend equivalents payable to certain directors and employees of Luther Burbank and its subsidiaries. You should be aware that the tax consequences to you of the merger may depend upon your own situation. In addition, you may be subject to state, local or foreign tax laws that are not discussed in this joint proxy statement/prospectus. You should therefore consult with your own tax advisor for a full understanding of the tax consequences to you of the merger.

For further information concerning U.S. federal income tax consequences of the merger, see the section entitled “Material United States Federal Income Tax Consequences of the Merger” beginning on page 121.

Q19: | What do I need to do now?

A19: | Read and consider the information contained in this joint proxy statement/prospectus, including the appendices, carefully and then please submit as soon as possible either your Washington Federal proxy, in the case of Washington Federal shareholders, or your Luther Burbank proxy, in the case of Luther Burbank shareholders.

Q20: | What is a “broker non-vote”?

A20: | Banks, brokers, trustees and other nominees who hold shares in street name for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, banks, brokers, trustees and other nominees are not allowed to exercise their voting discretion with respect to the approval of matters determined to be “non-routine” without specific instructions from the beneficial owner.

A broker non-vote occurs when a bank, broker, trustee or other nominee is not permitted to vote on a “non-routine” matter without instructions from the beneficial owner of the shares and the beneficial owner fails to provide the bank, broker, trustee or other nominee with such instructions. Broker non-votes only count toward a quorum if at least one proposal is presented with respect to which the bank, broker, trustee or other nominee has discretionary authority. It is expected that all proposals to be voted on at

6

##### Table of Contents

each of the Washington Federal special meeting and the Luther Burbank special meeting will be “non-routine” matters, and, as such, broker non-votes, if any, will not be counted as present and entitled to vote for purposes of determining a quorum at the Washington Federal special meeting or the Luther Burbank special meeting. If your bank, broker, trustee or other nominee holds your shares of Washington Federal common stock or Luther Burbank common stock in “street name,” such entity will vote your shares of Washington Federal common stock or Luther Burbank common stock only if you provide instructions on how to vote by complying with the instructions provided to you by your bank, broker, trustee or other nominee with this joint proxy statement/prospectus.

If you are a beneficial owner of Washington Federal common stock and you do not instruct your bank, broker, trustee or other nominee on how to vote your shares of Washington Federal common stock:

| • |  | Washington Federal share issuance proposal: your bank, broker, trustee or other nominee may not vote your shares on the Washington Federal share issuance proposal, which broker non-votes, if any, will have no effect on such proposal; and

| • |  | Washington Federal adjournment proposal: your bank, broker, trustee or other nominee may not vote your shares on the Washington Federal adjournment proposal, which broker non-votes, if any, will have no effect on the outcome of such proposal.

If you are a beneficial owner of Luther Burbank common stock and you do not instruct your bank, broker, trustee or other nominee on how to vote your shares of Luther Burbank common stock:

| • |  | Luther Burbank merger proposal: your bank, broker, trustee or other nominee may not vote your shares on the Luther Burbank merger proposal, which broker non-votes, if any, will have the same effect as a vote “AGAINST” such proposal;

| • |  | Luther Burbank compensation proposal: your bank, broker, trustee or other nominee may not vote your shares on the Luther Burbank compensation proposal, which broker non-votes, if any, will have no effect on the outcome of such proposal; and

| • |  | Luther Burbank adjournment proposal: your bank, broker, trustee or other nominee may not vote your shares on the Luther Burbank adjournment proposal, which broker non-votes, if any, will have no effect on the outcome of such proposal.

Q21: | If I am a holder of Luther Burbank common stock in certificated form, should I send in my Luther Burbank stock certificates now?

A21: | No. Please do not send in your Luther Burbank stock certificates with your proxy. After completion of the merger, Broadridge Corporate Issuer Solutions, Inc., as the exchange agent under the merger agreement (the “exchange agent”), will send you instructions for exchanging Luther Burbank stock certificates for the merger consideration. See the section entitled “The Merger Agreement — Procedures for Exchanging Shares of Luther Burbank Common Stock — Exchange Procedures” beginning on page 104.

Q22: | What should I do if I hold my shares of Luther Burbank common stock in book-entry form?

A22: | You are not required to take any special additional actions if your shares of Luther Burbank common stock are held in book-entry form. After the completion of the merger, the exchange agent will send you instructions for converting your book entry shares for the merger consideration. See the section entitled “The Merger Agreement — Procedures for Exchanging Shares of Luther Burbank Common Stock — Exchange Procedures” beginning on page 104.

Q23: | What do I do if I receive more than one joint proxy statement/prospectus or set of voting instructions?

A23: | Washington Federal shareholders and Luther Burbank shareholders may receive more than one set of voting materials, including multiple copies of this joint proxy statement/prospectus and multiple proxy cards or voting instruction cards. For example, if you hold shares of Washington Federal common stock

##### Table of Contents

| or Luther Burbank common stock in more than one brokerage account, you will receive a separate voting instruction card for each brokerage account in which you hold such shares. If you are a holder of record of Washington Federal common stock or Luther Burbank common stock and your shares are registered in more than one name, you will receive more than one proxy card. In addition, if you are a holder of both Washington Federal common stock and Luther Burbank common stock, you will receive one or more separate proxy cards or voting instruction cards for each company. Please complete, sign, date and return each proxy card and voting instruction card that you receive or otherwise follow the voting instructions set forth in this joint proxy statement/prospectus to ensure that you vote every share of Washington Federal common stock and/or Luther Burbank common stock that you own.

Material United States Federal Income Tax Consequences of the Merger (Page 121)

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 completion of the merger that Washington Federal and Luther Burbank each receive a legal opinion to that effect.

Assuming the merger qualifies as a reorganization, subject to the limitations and more detailed discussion set forth in “Material United States Federal Income Tax Consequences of the Merger” beginning on page 121, a Luther Burbank shareholder that is a U.S. holder generally will not recognize income, gain or loss on the exchange of Luther Burbank common stock for Washington Federal common stock in the merger, other than with respect to cash received (i) in lieu of fractional shares of Washington Federal common stock or (ii) on account of accrued dividends and dividend equivalents payable to certain directors and employees of Luther Burbank and its subsidiaries.

Tax matters are complicated, and the tax consequences of the merger to a particular Luther Burbank shareholder will depend in part on such shareholder’s individual circumstances. Accordingly, each Luther Burbank shareholder is urged to consult his or her own tax advisor for a full understanding of the tax consequences of the merger to such shareholder, including the applicability and effect of federal, state, local and foreign income and other tax laws.

As of the Luther Burbank record date, each director and certain executive officers of Luther Burbank who own shares of Luther Burbank common stock, who collectively beneficially own an aggregate of approximately 23.19% of the outstanding Luther Burbank common stock have each entered into the shareholder agreements with Luther Burbank and Washington Federal pursuant to which he or she agreed, among other things, to vote all shares of Luther Burbank common stock beneficially owned by him or her in favor of adoption and approval of the merger agreement, the merger and any other matters required to be approved for the consummation of the merger agreement at any meeting of the shareholders of Luther Burbank, subject to certain conditions set forth therein. The form of shareholder agreement is attached as Annex A to the merger agreement, which is attached as Appendix A to this joint proxy statement/prospectus.

Completion of the merger depends on meeting a number of conditions, including the following:

| • |  | shareholders of Washington Federal must approve the issuance of Washington Federal common stock in the merger;

| • |  | shareholders of Luther Burbank must approve the merger agreement and the merger;

| • |  | Washington Federal and Luther Burbank must file all notices and applications, and receive all regulatory approvals, required to consummate the merger and the bank merger and such approvals must remain in full force and effect, and any waiting periods required by law must have expired and no such approval may contain any conditions, restrictions or requirements that would require Washington Federal or Luther Burbank to take any action or commit to take any action that would reasonably be likely to have a material adverse effect (as defined in the merger agreement) on Washington Federal after giving effect to the merger (measured on a scale relative to Luther Burbank and its subsidiaries, taken as a whole);

| • |  | no statute, rule, regulation, judgment, decree, injunction or other order which is in effect and prohibits or makes illegal the consummation of the merger will have been enacted, issued, promulgated, enforced or entered by a governmental authority of competent jurisdiction;

| • |  | the registration statement of Washington Federal, of which this document is a part, must have become effective under the Securities Act of 1933 (the “Securities Act”), and no stop order suspending the effectiveness of such registration statement will have been issued and no proceedings for that purpose will have been initiated or threatened by the SEC and not withdrawn;

| • |  | the Washington Federal common stock to be issued to Luther Burbank shareholders as the merger consideration in the merger must have been approved for trading on the NASDAQ;

| • |  | the representations and warranties made by each of Washington Federal and Luther Burbank in the merger agreement must be true and correct, subject to the materiality standards and other qualifications provided in the merger agreement, as of the date of the merger agreement and as of the effective time of the merger, except for certain inaccuracies that would not have, or would not reasonably be expected to have, a material adverse effect;

| • |  | Washington Federal and Luther Burbank must have complied in all material respects with their respective obligations in the merger agreement;

| • |  | Washington Federal must have received such certificates of Luther Burbank’s officers or others and such other documents to evidence fulfillment of the conditions to its obligations as Washington Federal may reasonably request;

Neither Washington Federal nor Luther Burbank can be certain whether or when any of the conditions to the merger will be satisfied, or waived where permissible, or that the merger will be completed.

Regulatory Approvals Required for the Merger (Page 99)

The closing of the merger is conditioned upon the receipt of all approvals of regulatory authorities required for the merger and the bank merger. Under the terms of the merger agreement, Washington Federal and Luther Burbank have agreed to use their reasonable best efforts to file all required notices and applications, and obtain all necessary permits, consents, approvals and authorizations from any governmental authority necessary to consummate the merger and the bank merger.

In order to complete the transactions contemplated by the merger agreement, Washington Federal and Luther Burbank must first file all required notices and obtain all regulatory approvals, consents and orders required in connection with both the merger and the bank merger. In this regard, the parties must obtain the approval of the FDIC and the approval of the Washington State Department of Financial Institutions (the “WDFI”) for the bank merger, and provide notice of the bank merger to the California Department of Financial Protection and Innovation (the “CDFPI”). Applications to merge the banks were filed with the FDIC on or about January 6, 2023, and the WDFI on or about January 9, 2023, and the notice to the CDFPI was filed on or about January 9, 2023.

Washington Federal was also advised by the CDFPI to file a request for an order of exemption pursuant to Section 1260 of the California Financial Code to avoid having to file a change of control application under Section 1251 of the California Financial Code for the momentary acquisition of control of LB Savings before it is merged with WaFd Bank. Finally, in connection with communications with the Federal Reserve Bank of San Francisco (the “FRBSF”), Washington Federal was advised that prior approval of the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) is not required for the merger and the momentary acquisition of control of LB Savings because it qualifies as a transaction not requiring Federal Reserve Board approval pursuant to 12 CFR 225.12(d)(2). Thus, a bank holding company application is not required for the transaction. Rather, Washington Federal must provide written notice of the proposed transaction to the FRBSF pursuant to the requirements of 12 CFR 225.12(d)(2). Washington Federal submitted the required notice to the FRBSF and the request for an exemption to the CDFPI on March 1, 2023. On March 21, 2023, WaFd Bank was notified that the CDFPI had approved the request for exemption via the issuance of an order of exemption.

Termination of the Merger Agreement (Page 118)

Washington Federal and Luther Burbank can mutually agree at any time to terminate the merger agreement before completing the merger, even if shareholders of Washington Federal or Luther Burbank have already voted to approve the Washington Federal share issuance proposal or the Luther Burbank merger proposal, respectively.

Washington Federal or Luther Burbank can also terminate the merger agreement:

| • |  | if the terminating party is not in material breach of any representation, warranty, covenant, or agreement contained in the merger agreement, in the event of a breach by the other party of any representation, warranty, covenant, or agreement contained in the merger agreement that (i) cannot be or has not been cured within 30 days after the giving of written notice to the breaching party of such breach and (ii) would entitle the non-breaching party not to consummate the merger;

| • |  | in the event that the merger is not consummated by November 30, 2023 (the “outside date”), except to the extent that the failure to consummate the merger by such date is due to (i) the failure of the party seeking to terminate to perform or observe its covenants and agreements set forth in the merger agreement, or (ii) the failure of any of the Luther Burbank shareholders (if Luther Burbank is the party seeking to terminate) to perform or observe their respective covenants under their respective shareholder agreements with Luther Burbank and Washington Federal; provided, that the outside date may be extended to February 29, 2024 by either party’s written notice to the other party if the closing has not occurred by the outside date due to the failure to receive all requisite regulatory approvals and

20

##### Table of Contents

| all other conditions to closing have been satisfied (other than conditions that are to be satisfied at closing and such conditions would have been capable of being satisfied on the outside date); or

| • |  | in the event the approval of any governmental authority required for consummation of the merger has been denied by final, non-appealable action of the governmental authority, or any governmental authority will have issued a final, non-appealable injunction permanently enjoining or otherwise prohibiting the consummation of the merger, or an application for approval has been permanently withdrawn by mutual agreement of Washington Federal and Luther Burbank at the formal or informal request of a governmental authority, provided that no party has the right to terminate the merger agreement if the party seeking to terminate the merger agreement failed to perform or observe its covenants set forth in the merger agreement.

In addition, Washington Federal may terminate the merger agreement if the requisite Luther Burbank shareholder approval has not been obtained by reason of the failure to obtain the required vote at the Luther Burbank special meeting or at any adjournment or postponement thereof.

Washington Federal may also terminate the merger agreement at any time prior to the Luther Burbank special meeting if (i) Luther Burbank has materially breached its covenants described under the section entitled “The Merger Agreement — No Solicitation” beginning on page 114 in any respect adverse to Washington Federal, (ii) the Luther Burbank board fails to recommend to the Luther Burbank shareholders that they approve the merger agreement and the merger, or withdraws, modifies or changes its recommendation to the Luther Burbank shareholders in a manner adverse in any respect to the interests of Washington Federal, or (iii) the Luther Burbank board fails to call, give notice of, convene or hold the Luther Burbank special meeting.

Washington Federal also may terminate the merger agreement if a tender offer or exchange offer for 15% or more of the outstanding Luther Burbank common stock is commenced (other than by Washington Federal or its subsidiaries) and the Luther Burbank board recommends that Luther Burbank shareholders tender their shares in such tender offer or exchange offer or otherwise fails to recommend that Luther Burbank shareholders reject the offer within a specified period.

Luther Burbank may also terminate the merger agreement if approval of the Washington Federal share issuance proposal has not been obtained by reason of the failure to obtain the required vote at the Washington Federal special meeting or at any adjournment or postponement thereof.

Luther Burbank may also terminate the merger agreement if, prior to the approval of the Luther Burbank merger proposal by Luther Burbank shareholders at the Luther Burbank special meeting or at any adjournment or postponement thereof, (i) the Luther Burbank board has, in compliance with the requirements of the merger agreement, authorized Luther Burbank to enter into a binding written agreement with respect to a superior proposal, as defined in the merger agreement, and (ii) Luther Burbank pays to Washington Federal the termination fee described below substantially concurrently with the termination of the merger agreement.

Termination Fee (Page 119)

Luther Burbank must pay Washington Federal a termination fee of $26.17 million (the “termination fee”) if the merger agreement is terminated under specified circumstances.

Amendment of the Merger Agreement (Page 120)

To the extent permitted under applicable law, the merger agreement may be amended or modified at any time by written agreement of the parties whether before or after the approval of the shareholders of Luther Burbank; provided, however, no amendment that by law requires further approval by the Luther Burbank

21

##### Table of Contents

shareholders may be made after the approval of the principal terms of the merger agreement by the Luther Burbank shareholders without first obtaining such approval.

Interests of Certain Luther Burbank Officers and Directors in the Merger (Page 91)

Luther Burbank directors and officers have interests in the merger as individuals that are in addition to, or different from, their interests as shareholders of Luther Burbank, which are:

| • |  | upon consummation of the merger, each outstanding award of Luther Burbank restricted stock and Luther Burbank restricted stock units issued pursuant to the Luther Burbank Omnibus Plan held by directors and executive officers who are not continuing employees will automatically vest in full and will be converted into, and will be cancelled in exchange for, the right to receive the merger consideration, plus the amount in cash equal to the sum of any accrued dividends or dividend equivalents that are payable in cash, pursuant to the terms of the Luther Burbank restricted stock or Luther Burbank restricted stock units;

| • |  | upon consummation of the merger, each outstanding share of Luther Burbank restricted stock and each Luther Burbank restricted stock unit held by an executive officer who is a continuing employee, to the extent expressly assumed by Washington Federal, will be substituted with an award of Washington Federal restricted stock or a Washington Federal restricted stock unit based on the exchange ratio;

| • |  | upon consummation of the merger, each outstanding share of Luther Burbank restricted stock and each Luther Burbank restricted stock unit held by an executive officer who is a continuing employee, to the extent not expressly assumed by Washington Federal, will automatically vest in full and will be converted into, and will be cancelled in exchange for, the right to receive the merger consideration, plus the amount in cash equal to the sum of any accrued dividends or dividend equivalents that are payable in cash, pursuant to the terms of the Luther Burbank restricted stock or Luther Burbank restricted stock units;

| • |  | cash payments to executive officers of Luther Burbank in the aggregate amount of approximately $12,752,998, on a pre-tax basis, as well as the continuation of health and welfare benefits for such executive officers, in each case, consisting of severance and certain other cash payments owed to such executive officers in connection with the merger pursuant to the term of their respective employment, severance, supplemental retirement, or other similar agreements with Luther Burbank;

| • |  | cash payments to Mr. Trione, the chair of the Luther Burbank board and the LB Savings board of directors (the “LB Savings board”) in the aggregate amount of approximately $6.4 million, on a pre-tax basis, consisting of certain cash payments owed to Mr. Trione in connection with the merger pursuant to the terms of Mr. Trione’s salary continuation agreement with Luther Burbank;

| • |  | Tammy Mahoney, Executive Vice President and Chief Risk Officer of Luther Burbank, has entered into an offer letter with Washington Federal, effective at the completion of the merger, which provides compensation to Ms. Mahoney for continued provision of services to, or employment with Washington Federal following the merger;

| • |  | the agreement of Washington Federal to honor indemnification obligations of Luther Burbank, as well as to maintain liability insurance for Luther Burbank directors and officers, each for a period of six years following the merger, subject to the terms of the merger agreement; and

| • |  | pursuant to the terms of the merger agreement, Washington Federal has agreed that, effective as of the effective time of the merger, each of the Washington Federal board and the WaFd Bank board of directors (the “WaFd Bank board”) will be comprised of 12 members, including two new directors, who will be recommended by Luther Burbank and be agreeable to Washington Federal (Washington Federal’s consent will not be unreasonably withheld, conditioned or delayed).

22

##### Table of Contents

In addition, the shareholder agreement entered into by Victor S. Trione, the Chairman of the Luther Burbank board and the LB Savings board, provides that Mr. Trione will not sell, transfer, pledge, hypothecate or otherwise dispose of more than one-third of his shares of Luther Burbank common stock during each 12-month period following the effective time of the merger until the expiration of 36 months from the effective time of the merger.

The Washington Federal board and the Luther Burbank board were aware of the foregoing interests and considered them among other matters, in approving the merger agreement and the merger.

Board of Directors and Officers of Washington Federal and WaFd Bank After the Merger (Page 98)

Except as described in the next sentence, the directors and officers of Washington Federal and WaFd Bank immediately prior to the effective time of the merger will be the directors and officers of Washington Federal and WaFd Bank following the merger until the earlier of their resignation or removal or until their respective successors are duly appointed and qualified. Washington Federal has agreed that, effective as of the effective time of the merger, each of the Washington Federal board and the WaFd Bank board will be comprised of 12 members, including two new directors, who will be recommended by Luther Burbank and be agreeable to Washington Federal (Washington Federal’s consent will not be unreasonably withheld, conditioned or delayed). Each such individual will serve until the next annual meeting of shareholders of Washington Federal at which the class of directors to which such individual will be appointed is presented to shareholders for reelection. In the event such an individual is appointed to a class of Washington Federal directors that will be presented to Washington Federal’s shareholders for reelection at an annual meeting of shareholders of Washington Federal held within 24 months following the closing date of the merger, Washington Federal is required to include such individual on the list of nominees for director presented by the Washington Federal board and for which the Washington Federal board will solicit proxies at such annual meeting of shareholders of Washington Federal, to serve for the applicable term of such individual’s class of directors and until such individual’s successor will be duly elected and qualified, provided, that such nomination and solicitation would not violate the fiduciary duties of the members of the Washington Federal board. The two new directors recommended by Luther Burbank will be selected from the five current independent members of the Luther Burbank board who are eligible to serve as a member of the Washington Federal board. Washington Federal and Luther Burbank have not yet determined the two existing directors of the Luther Burbank board who will be appointed or elected to the Washington Federal board and the WaFd Bank board.

Accounting Treatment of the Merger (Page 99)

The merger will be accounted for under the acquisition method of accounting under U.S. generally accepted accounting principles, or GAAP.

Assumption of Luther Burbank Debt Obligations (Page 113)

Washington Federal has agreed to assume, or to cause one of its subsidiaries to assume, Luther Burbank’s obligations under Luther Burbank’s 6.50% senior unsecured term notes (the “senior notes”) and Luther

Burbank’s fixed/floating rate junior subordinated deferrable interest debentures (the “subordinated debentures” and, together with the senior notes, the “Luther Burbank debt obligations”). As of December 31, 2022, an aggregate principal amount of $95,000,000 of the senior notes was outstanding and an aggregate principal amount of $61,857,000 of the subordinated debentures was outstanding.

Comparison of the Rights of Shareholders (Page 137)

The rights of shareholders of Washington Federal differ from the rights of shareholders of Luther Burbank. Washington Federal is incorporated under the laws of the State of Washington and Luther Burbank is

23

##### Table of Contents

incorporated under the laws of the State of California. The rights of holders of Washington Federal common stock are governed by the Washington Business Corporations Act (the “WBCA”), as well as the Washington Federal articles and the Washington Federal bylaws. The rights of holders of Luther Burbank common stock are governed by the CGCL, as well as the Amended and Restated Articles of Incorporation of Luther Burbank (the “Luther Burbank articles”) and the Amended and Restated Bylaws of Luther Burbank Corporation (the “Luther Burbank bylaws”). Following the closing of the merger, shareholders of Luther Burbank will receive shares of Washington Federal common stock in exchange for their shares of Luther Burbank common stock and become shareholders of Washington Federal, and their rights as shareholders of Washington Federal will be governed by the Washington Federal articles, the Washington Federal bylaws and the WBCA.

Risk Factors (Page 25)

Before voting at the Washington Federal special meeting or the Luther Burbank special meeting, you should carefully consider all of the information contained in or incorporated by reference into this joint proxy statement/prospectus, including the risk factors set forth in the section entitled “Risk Factors” beginning on page 25. You should also read and consider the risk factors relating to the businesses of Washington Federal and ownership of Washington Federal common stock described in Part I, Item 1A of Washington Federal’s Annual Report on Form 10-K for the year ended September 30, 2022 that has been filed with the SEC, as well as any subsequent documents filed by Washington Federal with the SEC, which are incorporated into this joint proxy statement/prospectus by reference. See the section entitled “Where You Can Find More Information” beginning on page 151. You should also read and consider risk factors relating to the businesses of Luther Burbank that will also affect the combined company after the merger. These risks are described in Part I, Item 1A of Luther Burbank’s Form 10-K for the year ended December 31, 2022 that has been filed by Luther Burbank with the SEC, as well as any subsequent documents filed by Luther Burbank with the SEC, which are incorporated into this joint proxy statement/prospectus by reference.

RISK FACTORS

An investment by Luther Burbank’s shareholders, as a result of the exchange of shares of Luther Burbank common stock for shares of Washington Federal common stock, is an investment in Washington Federal as combined with Luther Burbank and involves certain risks. Similarly, a decision on the part of Washington Federal shareholders to approve the Washington Federal share issuance proposal also involves risks for Washington Federal shareholders, who will continue to hold their shares of Washington Federal common stock after the merger. Certain material risks and uncertainties connected with the merger agreement and transactions contemplated thereby, including the merger, the bank merger, and ownership of Washington Federal common stock are discussed below. In addition, Washington Federal and Luther Burbank have discussed certain other material risks connected with the ownership of Washington Federal common stock and with Washington Federal’s business, and with the ownership of Luther Burbank common stock and Luther Burbank’s business, respectively, under the caption “Risk Factors” appearing in their respective Annual Reports on Form 10-K most recently filed with the SEC, and may include additional or updated disclosures of such material risks in its subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K that each has filed with the SEC or may file with the SEC after the date of this joint proxy statement/prospectus.

Washington Federal shareholders and Luther Burbank shareholders should carefully read and consider all of these risks and all other information contained in this joint proxy statement/prospectus, including the matters addressed in the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 34 and the discussions of risk factors included in the documents incorporated by reference in this joint proxy statement/prospectus, in deciding whether to vote for approval of the various proposals for which they may be entitled to vote at the Washington Federal special meeting or the Luther Burbank special meeting, as applicable. The risks described in this joint proxy statement/prospectus and in those documents incorporated by reference may adversely affect the value of Washington Federal common stock that you, as an existing Washington Federal shareholder, currently hold or that you, as an existing Luther Burbank shareholder, will hold upon consummation of the merger, and could result in a significant decline in the value of Washington Federal common stock and cause you to lose all or part of the value of your investments in Washington Federal common stock.

Risks Related To The Merger

Because the market price of Washington Federal common stock will fluctuate, Luther Burbank shareholders cannot be sure of the value of the merger consideration they will receive.

Upon completion of the merger, each outstanding share of Luther Burbank common stock will, subject to the provisions of the merger agreement, be converted into 0.3353 of a share of Washington Federal common stock. This exchange ratio is fixed and will not be adjusted to reflect changes in the market prices of Washington Federal common stock or Luther Burbank common stock. Any change in the market price of Washington Federal common stock prior to completion of the merger could affect the value of the merger consideration that Luther Burbank shareholders will receive upon completion of the merger. Neither Washington Federal nor Luther Burbank is permitted to terminate the merger agreement or resolicit the vote of its shareholders solely because of changes in the market prices of either company’s common stock.

Stock price changes may result from a variety of factors, including general market and economic conditions, changes in our respective businesses, operations and prospects, the recent volatility in the prices of securities in global financial markets, including the market prices of Washington Federal and Luther Burbank and other banking companies, the performance of peer companies and other financial companies, regulatory considerations and tax laws, and the effects of public health crises, such as the COVID-19 pandemic, and the governmental and other responses thereto, many of which are beyond Washington Federal’s and Luther Burbank’s control. Therefore, at the time of the Washington Federal special meeting and the Luther Burbank special meeting, Washington Federal shareholders and Luther Burbank shareholders will not know the market value of the

25

##### Table of Contents

consideration that Luther Burbank shareholders will receive at the effective time of the merger. You should obtain current market quotations for shares of Washington Federal common stock (NASDAQ: WAFD) and for shares of Luther Burbank common stock (NASDAQ: LBC).

The market price of Washington Federal common stock after the merger may be affected by factors different from those currently affecting the shares of Washington Federal common stock or Luther Burbank common stock.

Upon completion of the merger, Luther Burbank shareholders will become Washington Federal shareholders. Washington Federal’s business differs from that of Luther Burbank and certain adjustments may be made to the combined company’s business as a result of the merger. Accordingly, the results of operations of the combined company and the market price of Washington Federal 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 Washington Federal and Luther Burbank. For a discussion of the businesses of Washington Federal and Luther Burbank 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 the section entitled “Where You Can Find More Information” beginning on page 151.

Washington Federal and Luther Burbank expect to incur substantial costs related to the merger and integration.

Washington Federal and Luther Burbank have incurred and expect to incur a number of non-recurring costs associated with the merger. These costs include legal, financial advisory, accounting, consulting and other advisory fees, severance/employee benefit-related costs, public company filing fees and other regulatory fees, financial printing and other printing costs and other related costs. Some of these costs are payable by either Washington Federal or Luther Burbank regardless of whether the merger is completed. See the section entitled “The Merger Agreement — Expenses” beginning on page 120.

Washington Federal and Luther Burbank have incurred and expect to incur significant, non-recurring costs in connection with negotiating the merger agreement and closing the merger. In addition, Washington Federal will incur integration costs following the completion of the merger as Washington Federal and Luther Burbank integrate their businesses, including facilities and systems consolidation costs and employment-related costs. Washington Federal and Luther Burbank may also incur additional costs to maintain employee morale and to retain key employees. There are a large number of processes, policies, procedures, operations, technologies and systems that may need to be integrated, including purchasing, accounting and finance, payroll, compliance, treasury management, branch operations, vendor management, risk management, lines of business, pricing and benefits. While Washington Federal and Luther Burbank have assumed that a certain level of costs will be incurred, there are many factors beyond their control that could affect the total amount or the timing of the integration costs. Moreover, many of the costs that will be incurred are, by their nature, difficult to estimate accurately. These integration costs may result in the combined company taking charges against earnings following the completion of the merger, and the amount and timing of such charges are uncertain at present. 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.

If Washington Federal is unable to integrate the combined operations successfully, its business and earnings may be negatively affected.

The merger involves the integration of companies that have previously operated independently. The success of the merger will depend, in part, on the ability to realize the anticipated cost savings from combining the businesses of Washington Federal and Luther Burbank. To realize the anticipated benefits and cost savings from the merger, Washington Federal must successfully integrate Luther Burbank’s operations in a manner that permits those cost savings to be realized, without adversely affecting current revenues and future growth. If

26

##### Table of Contents

Washington Federal and Luther Burbank 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.

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 following the completion of the merger, which may adversely affect the value of the common stock of the combined company following the completion of the merger.

Washington Federal and Luther Burbank 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 Washington Federal and Luther Burbank during this transition period and for an undetermined period after completion of the merger on the combined company.

Each of Washington Federal’s shareholders and Luther Burbank’s shareholders will have less influence as a shareholder of the combined company than as a shareholder of Washington Federal or Luther Burbank individually, as applicable.

Washington Federal shareholders and Luther Burbank shareholders currently have the right to vote in the election of the board of directors and on other matters affecting Washington Federal and Luther Burbank, respectively. Following completion of the merger, the shareholders of Luther Burbank as a group are expected to hold a maximum ownership interest of approximately 21% of Washington Federal. When the merger occurs, each Washington Federal and Luther Burbank shareholder will become a shareholder of Washington Federal with a percentage ownership of the combined company smaller than such shareholder’s percentage ownership of Washington Federal common stock or Luther Burbank common stock, respectively, prior to the completion of the merger. Because of this, Luther Burbank’s shareholders will have less influence on the management and policies of Washington Federal than they now have on the management and policies of Luther Burbank, and Washington Federal’s shareholders will have less influence on the management and policies of the combined company than they now have on the management and policies of Washington Federal.

Washington Federal’s entry into California may present increased risk that may adversely impact Washington Federal’s business, prospects and financial condition.

The merger will result in Washington Federal’s initial entry into the state of California where Washington Federal has no operating experience. Although Washington Federal will retain a number of Luther Burbank’s lending and business development officers with experience in the California market, Washington Federal is new to this market area. The banking and financial services business in California is highly competitive. The entry of Washington Federal into California will present Washington Federal with different competitive conditions and Washington Federal will be required to compete for loans, deposits and customers for financial services with other commercial banks, savings and loan associations, securities and brokerage companies, mortgage companies, insurance companies, finance companies, money market funds, credit unions and other nonbank financial service providers in California. Many of these competitors are much larger in total assets and capitalization, have greater access to capital markets and offer a broader array of financial services than Luther

Burbank or Washington Federal. As a result, there can be no assurance that Washington Federal will be able to compete effectively in California, and the results of operations of Washington Federal could be materially and adversely affected if Washington Federal is unable to compete effectively.

##### Table of Contents

Because the fair value of the assets held by each of Luther Burbank and Washington Federal as a result of the merger may fluctuate as a result of changes in interest rates, an adverse change prior to the closing of the merger may reduce or eliminate the anticipated benefits of the merger for Luther Burbank or Washington Federal shareholders.

Any change in the market interest rates applicable to Washington Federal or Luther Burbank prior to completion of the merger could affect the value of the assets held by either or both of Luther Burbank and Washington Federal. The magnitude of any such changes would not necessarily be equal between Luther Burbank and Washington Federal, and consequently the relative value of the assets held by each company may be altered in a way that is material to either company or the anticipated benefits of the merger. Prior to the closing of the merger and at the time of the Luther Burbank special meeting and the Washington Federal special meeting, Luther Burbank or Washington Federal shareholders, as applicable, will not necessarily know or be able to calculate how market interest rates may change, if at all, and the impact any such change would have on the value of assets held by Luther Burbank or Washington Federal, as applicable.

Upon the closing of the merger, the combined company will need to adjust the fair value of Luther Burbank’s investment and loan portfolios. The rising interest rate environment could have the effect of increasing the magnitude of the purchase accounting marks relating to such fair value adjustments, thereby increasing initial tangible book value dilution, extending the tangible book value earn-back period, and negatively impacting the combined company’s capital ratios, which may result in the combined company taking steps to strengthen its capital position.

Should market interest rates rise in the future, it would have a negative effect on estimates of the fair value of loans and other assets held by Luther Burbank and Washington Federal, which could be material and, in certain cases, may result in realized losses or require write-downs that could have a material effect on either company’s earnings or financial condition. The fair value of an obligation with a fixed interest rate generally decreases when prevailing interest rates rise, and the fair value of an obligation with an adjustable interest rate can be adversely affected when interest rates increase due to a lag in the implementation of repricing terms as well as due to interest rate caps which may limit the amount of increase in such obligation’s interest rate. Interest rate changes may result from a variety of factors, including general market and economic conditions, actions of central banks or other governmental authorities, regulatory considerations and the effects of SARS-CoV-2 or COVID-19, or any variants, evolutions or mutations thereof, or any other viruses (including influenza), and the governmental and other responses thereto (including any pandemic measures). These factors are generally beyond the control of both companies. Neither Washington Federal nor Luther Burbank is permitted to terminate the merger agreement or resolicit the vote of its shareholders solely because of changes in market interest rates.

The opinion of Washington Federal’s financial advisor received by the Washington Federal board and the opinion of Luther Burbank’s financial advisor received by the Luther Burbank board do not reflect any changes since the date of such opinions, each of which was delivered prior to the signing of the merger agreement.

Changes in the operations and prospects of Washington Federal or Luther Burbank, general market and economic conditions and other factors that may be beyond the control of Washington Federal and Luther Burbank may alter the value of Washington Federal or Luther Burbank or the market price for shares of Washington Federal common stock or Luther Burbank common stock by the time the merger is completed. Neither the opinion delivered by KBW to the Washington Federal board nor the opinion delivered by Piper Sandler to the Luther Burbank board speaks as of any date other than the date of such opinion, which was

For a description of the other factors considered by the Washington Federal board in determining to approve the merger, see the section entitled “The Merger — Recommendation of the Washington Federal Board and Reasons of Washington Federal for the Merger” beginning on page 56. For a description of the other factors considered by the Luther Burbank board in determining to approve the merger, see the section entitled “The Merger — Recommendation of the Luther Burbank Board and Reasons of Luther Burbank for the Merger” beginning on page 73.

The merger agreement limits Luther Burbank’s ability to pursue alternatives to the merger and may discourage other companies from trying to acquire Luther Burbank.

Until the completion of the merger, with certain limited exceptions, Luther Burbank is prohibited from soliciting, initiating, knowingly encouraging or participating in any discussion of or otherwise considering any inquiries or proposals that may lead to an acquisition proposal, such as a merger or other business combination transaction with any person other than Washington Federal. Although the Luther Burbank board is permitted to take certain actions in connection with the receipt of a competing acquisition proposal if it determines in good faith that the failure to do so would more likely than not result in a breach of its fiduciary duties, taking such actions could, and other actions (such as withdrawing or modifying its recommendation to Luther Burbank shareholders that they vote in favor of approval of the merger agreement and the merger) would, entitle Washington Federal to terminate the merger agreement and receive the termination fee. See the section entitled “The Merger Agreement — Termination of the Merger Agreement” beginning on page 118 and “The Merger Agreement — Termination Fee” beginning on page 119. These provisions might discourage a potential competing acquiror that might have an interest in acquiring all or a significant part of Luther Burbank from considering or proposing that acquisition even if such acquiror was willing to offer a greater merger consideration to Luther Burbank shareholders than the merger consideration that Washington Federal has offered in the merger. The payment of the termination fee could also have an adverse impact on Luther Burbank’s financial condition.

The unaudited pro forma condensed combined financial information included in this joint proxy statement/prospectus is preliminary and the actual consideration to be issued in the merger as well as 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 is 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 Luther Burbank identifiable assets acquired and liabilities assumed at fair value and the resulting goodwill recognized. The merger consideration value allocation reflected in this document is preliminary, and the final allocation thereof will be based upon the value of the actual merger consideration and the fair value of the assets and liabilities of Luther Burbank as of the closing date. Accordingly, the actual value of the merger consideration may vary significantly from the value used in preparing the unaudited pro forma condensed combined financial information in this document. Further, the final acquisition accounting adjustments may differ materially from the pro forma adjustments reflected in this document. For more information, see the section entitled “Unaudited Pro Forma Condensed Combined Financial Information” beginning on page 125. Any potential decline in the combined company’s financial condition or results of operations may cause significant variations in the stock price of the combined company.

Each of Washington Federal and Luther Burbank will be subject to business uncertainties and contractual restrictions while the merger is pending.

Washington Federal and Luther Burbank have operated and, until the completion of the merger, will continue to operate, independently. Uncertainty about the effect of the merger on employees and customers may have an adverse effect on Luther Burbank and Washington Federal. These uncertainties may impair Luther Burbank’s and Washington Federal’s ability to attract, retain or motivate key personnel until the merger is consummated, and could cause customers and others that deal with Luther Burbank and Washington Federal to seek to change existing business relationships with Luther Burbank and Washington Federal. Retention of certain employees may be challenging during the pendency of the merger, as certain employees may experience uncertainty about their future roles with Washington Federal. If key employees depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Washington Federal, Washington Federal’s business following the merger could be harmed. In addition, subject to certain exceptions, Washington Federal and Luther Burbank have each agreed to operate its business in the ordinary and usual course consistent with past practice and to refrain from taking certain actions that may adversely affect its ability to consummation the transactions contemplated by the merger agreement on a timely basis without the consent of the other party. These restrictions may prevent Washington Federal and/or Luther Burbank from pursuing attractive business opportunities that may arise prior to the completion of the merger. See the section entitled “The Merger Agreement — Covenants and Agreements — Conduct of Businesses Pending the Merger” beginning on page 106 for a description of the restrictive covenants applicable to Washington Federal and Luther Burbank.

Luther Burbank’s directors and executive officers have additional interests in the merger.

In deciding how to vote on the Luther Burbank merger proposal, you should be aware that Luther Burbank’s respective directors and executive officers might have interests in the merger that are different from, or in addition to, the interests of Luther Burbank shareholders generally. See the section entitled “The Merger — Interests of Certain Luther Burbank Officers and Directors in the Merger” beginning on page 91. The Luther Burbank board was aware of these interests related to directors and executive officers of Luther Burbank and considered them when it recommended approval of the Luther Burbank merger proposal to the Luther Burbank shareholders.

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 Washington Federal following the merger.

Before the merger and the bank merger may be completed, Washington Federal and Luther Burbank must obtain approvals, waivers or exemptions from the FDIC, the CDFPI and the WDFI, as applicable, and file notices with the Federal Reserve Board and the CDFPI. Other approvals, waivers or consents from regulators may also be required. An adverse development in either party’s regulatory standing or other factors could result in an inability to obtain approvals or delay their receipt. 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 (which have been received, as described below), investigations or opposition, or changes in legislation or the political environment generally. The regulators may impose conditions on the completion of the merger or the bank merger or require changes to the terms of the merger or the bank merger. While Washington Federal and Luther Burbank do not believe that any such conditions or changes would be appropriate, there can be no assurance that they will not be imposed, and such conditions or changes could have the effect of delaying or preventing completion of the merger or imposing additional costs on or limiting the revenues of Washington Federal following the merger, any of which might have an adverse effect on Washington Federal following the merger. Neither Washington Federal nor Luther Burbank is obligated to complete the merger if the regulatory approvals received in connection with the completion of the merger impose any conditions, restrictions or requirements that require Washington Federal or Luther Burbank to take any action or commit to take any action that would reasonably be likely to have a “material adverse effect” (as defined in the merger agreement) on Washington

Federal (measured on a scale relative to Luther Burbank and its subsidiaries, taken as a whole). See the sections entitled “The Merger — Regulatory Approvals Required for the Merger” beginning on page 99 and “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 115.

In a February 3, 2023 comment letter to the FDIC (the “CRC letter”), the California Reinvestment Coalition (the “CRC”) requested that the FDIC extend the comment period and hold public hearings on the bank merger application, and urged the FDIC to deny the bank merger application. The CRC letter was co-signed by other community groups and organizations.

Washington Federal and Luther Burbank became aware of the CRC letter in connection with a press release issued by the CRC on February 7, 2023. Neither Washington Federal nor Luther Burbank had an opportunity to discuss with the CRC the issues raised in the CRC letter before it was released and, thus, did not immediately address, respond to or provide any specific comments on the issues raised in the CRC letter. Since becoming aware of the CRC letter, Washington Federal and Luther Burbank have reached out to the CRC to establish a dialogue to understand their concerns regarding the bank merger. Both Washington Federal and Luther Burbank appreciate that the CRC and its partner organizations have a role in connection with the bank merger process, and more importantly have a voice with respect to the communities to be served and future communities that may be served by the resulting institution, if the bank merger is approved. Accordingly, Washington Federal and Luther Burbank intend to work cooperatively with the CRC and its partner organizations to review and address their concerns; however, despite the best of intentions of all parties concerned, there can be no assurance that these efforts will be successful. If Washington Federal and Luther Burbank are not able to reach a constructive solution to address the concerns raised by the CRC and its partner organizations, it is possible that conditions of approval could be imposed by the regulators on the completion of the bank merger, or the regulators could require changes to the terms of the merger or bank merger. Any such conditions or changes could delay or prevent completion of the merger or bank merger, and impose excessive costs on or limit revenues of the resulting institution. As noted above, if any of such conditions or changes could have an adverse effect on the resulting institution, both Washington Federal and Luther Burbank have the ability to terminate the merger agreement. See — “Regulatory approvals may not be received, may take longer than expected or may impose conditions that are not presently anticipated of that could have an adverse effect on Washington Federal following the merger” above.

In another comment letter on the bank merger application, dated February 1, 2023 (received by Washington Federal on or about February 21, 2023), Southern Dallas Progress (“SDP”), a community development corporation, indicated that it does not support the bank merger application, and requested that the FDIC deny the application. Consistent with the approach being taken with respect to the CRC letter, Washington Federal is reaching out to SDP to establish a dialogue to understand their concerns regarding the bank merger. While Washington Federal intends to work cooperatively with SDP, as with the discussions with the CRC, there can be no assurance that these efforts will be successful.

The merger is subject to certain closing conditions that, if not satisfied or waived, will result in the merger not being completed, which may cause the price of Washington Federal common stock or Luther Burbank common stock to decline.

The consummation of the merger is subject to customary conditions to closing, including the receipt of required regulatory approvals and approval of Luther Burbank’s shareholders. If any condition to the merger agreement is not satisfied or waived, to the extent permitted by law, the merger will not be completed. In addition, Washington Federal and Luther Burbank may terminate the merger agreement under certain circumstances, even if Luther Burbank’s shareholders approve the merger agreement and the merger. If Washington Federal and Luther Burbank do not complete the merger, the trading prices of Washington Federal common stock or Luther Burbank common stock on the NASDAQ may decline. In addition, neither company would realize any of the expected benefits of having completed the merger. If the merger is not completed and the Luther Burbank board seeks another merger or business combination, Luther Burbank shareholders cannot be certain that Luther Burbank will

##### Table of Contents

be able to find a party willing to offer equivalent or more attractive consideration than the consideration Washington Federal has agreed to provide. If the merger is not completed, additional risks could materialize, which could materially and adversely affect the business, financial condition and results of Washington Federal and Luther Burbank, including the recognition of the expenses relating to the merger without realizing the economic benefits of the merger. For more information on closing conditions to the merger agreement, see the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 115.

The shares of Washington Federal common stock to be received by Luther Burbank shareholders as a result of the merger will have different rights from the shares of Luther Burbank common stock.

In the merger, Luther Burbank shareholders will become Washington Federal shareholders and their rights as shareholders will be governed by Washington law and the governing documents of Washington Federal following the merger. The rights associated with Washington Federal common stock are different from the rights associated with Luther Burbank common stock. See the section entitled “Comparison of the Rights of Shareholders” beginning on page 137 for a discussion of the different rights associated with Washington Federal common stock.

Issuance of shares of Washington Federal common stock in connection with the merger may adversely affect the market price of Washington Federal common stock.

In connection with the payment of the merger consideration, Washington Federal expects to issue 17,135,074 shares of Washington Federal common stock to Luther Burbank shareholders. The issuance of these new shares of Washington Federal common stock may result in fluctuations in the market price of Washington Federal common stock, including a stock price decrease.

Shareholder litigation could prevent or delay the completion of the merger or otherwise negatively impact the business and operations of Washington Federal and Luther Burbank.

Shareholders of Washington Federal and/or Luther Burbank may file lawsuits against Washington Federal, Luther Burbank and/or the directors and officers of either company in connection with the merger. One of the conditions to the closing is that no statute, rule, regulation, judgment, decree, injunction or other order issued by any court or governmental entity of competent jurisdiction or other legal restraint preventing the consummation of the merger, the bank merger or any of the other transactions contemplated by the merger agreement be in effect. If any plaintiff were successful in obtaining an injunction prohibiting Washington Federal or Luther Burbank defendants from completing the merger, the bank merger or any of the other transactions contemplated by the merger agreement, then such injunction may delay or prevent the effectiveness of the merger and could result in significant costs to Washington Federal and/or Luther Burbank, including any cost associated with the indemnification of directors and officers of each company. Washington Federal and Luther Burbank 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 Washington Federal and Luther Burbank and could prevent or delay the completion of the merger.

Risks Related to Washington Federal and Washington Federal’s Business

You should read and consider risk factors specific to Washington Federal’s business that will also affect the combined company after the merger. Washington Federal is, and will continue to be, subject to the risks described in Washington Federal’s Annual Report on Form 10-K for the fiscal year ended September 30, 2022, as updated by subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K, all of which are filed with the SEC and incorporated by reference into this joint proxy statement/prospectus.

| • |  | the Washington Federal adjournment proposal.

No other business may be conducted at the Washington Federal special meeting. A copy of the merger agreement is included in this joint proxy statement/prospectus as Appendix A, and the Washington Federal shareholders are encouraged to read it carefully in its entirety.

Voting Your Shares of Washington Federal Common Stock

Shareholders of Record

Washington Federal shareholders of record may vote their shares of Washington Federal common stock using one of the following methods:

| • |  | Vote through the Internet at www.proxyvote.com;

| • |  | Vote by telephone using the toll-free number shown on the proxy card; or

| • |  | Complete and return a written proxy card.

Votes submitted through the Internet or by telephone must be received by 11:59 p.m., Eastern Time, on May 3, 2023. Internet and telephone voting are available 24 hours a day, and if you use one of those methods, you do not need to return a proxy card.

You can also vote virtually at the special meeting, and submitting your voting instructions by any of the methods mentioned above will not affect your right to attend the special meeting and vote.

Shares Held in “Street Name”

If a Washington Federal shareholder’s shares of Washington Federal common stock are held through a bank, broker or other nominee, such Washington Federal shareholder is considered the beneficial owner of such shares held in “street name.” In such case, this joint proxy statement/prospectus has been forwarded by such Washington Federal shareholder’s bank, broker or other nominee, who is considered, with respect to such shares, the shareholder of record. As the beneficial owner, a Washington Federal shareholder has the right to direct such bank, broker or other nominee how to vote the shares by following the voting instructions that they have sent, or will send, to the Washington Federal shareholder. Without specific instructions from the Washington Federal shareholder, which will result in a broker non-vote, the bank, broker or other nominee is not empowered to vote a Luther Burbank shareholder’s shares on non-routine matters such as the Washington Federal merger proposal or the Washington Federal adjournment proposal. Not voting these shares will not have any effect on the approval of the Washington Federal merger proposal or the Washington Federal adjournment proposal. When the vote is tabulated for the proposals, as described below, broker non-votes, if any, will not be counted for purposes of determining whether a quorum is present. Accordingly, we advise each Washington Federal shareholder to promptly give instructions to his or her bank, broker or other nominee to vote “FOR” approval of the Washington Federal share issuance proposal and “FOR” approval of the Washington Federal adjournment proposal.

If a Washington Federal shareholder is a beneficial owner and wishes to vote at the Washington Federal special meeting, the Washington Federal must provide a proxy executed in such Washington Federal shareholder’s favor by the bank, broker or other nominee.

Proxy Revocation Procedures

Washington Federal shareholders may revoke a proxy at any time by:

| • |  | sending written notice of revocation to the corporate secretary of Washington Federal prior to the Washington Federal special meeting, addressed to Washington Federal, Inc., Attn: Corporate Secretary, 425 Pike Street, Seattle, Washington 98101;

| • |  | executing and delivering a proxy for the Luther Burbank special meeting bearing a later date; or

37

##### Table of Contents

| • |  | attending the special meeting and voting virtually. Attendance at the special meeting will not automatically revoke a proxy, but a shareholder in attendance may request a ballot and vote virtually thereby revoking a prior granted proxy.

If a Washington Federal shareholder has instructed a bank, broker or other nominee to vote such Washington Federal shareholder’s shares of Washington Federal common stock, the Washington Federal shareholder must follow directions received from the bank, broker or other nominee to change his or her vote.

Voting of Proxies

Proxies (including those given through voting by telephone or Internet) received by Washington Federal before or at the Washington Federal special meeting (and not revoked) by a holder of Washington Federal common stock will be voted in accordance with the instructions indicated thereon. Proxies that do not provide the proxy holders with direction in voting on the Washington Federal share issuance proposal or with respect to the Washington Federal adjournment proposal will be voted “FOR” approval of the Washington Federal share issuance proposal and “FOR” approval of the Washington Federal adjournment proposal, in accordance with the recommendation of the Washington Federal board.

Broker Non-Votes

A broker non-vote occurs when a bank, broker, trustee or other nominee is not permitted to vote on a “non-routine” matter without instructions from the beneficial owner of the shares and the beneficial owner fails to provide the bank, broker, trustee or other nominee with such instructions. Broker non-votes only count toward a quorum if at least one proposal is presented with respect to which the bank, broker, trustee or other nominee has discretionary authority. It is expected that all proposals to be voted on at the Washington Federal special meeting will be “non-routine” matters, and, as such, broker non-votes, if any, will not be counted as present and entitled to vote for purposes of determining a quorum at the Washington Federal special meeting. If your bank, broker, trustee or other nominee holds your shares of Washington Federal common stock in “street name,” such entity will vote your shares of Washington Federal common stock only if you provide instructions on how to vote by complying with the voter instruction form sent to you by your bank, broker, trustee or other nominee with this joint proxy statement/prospectus.

Quorum

The presence, virtually or by proxy, of at least a majority of the total number of outstanding shares of Washington Federal common stock entitled to vote is necessary to constitute a quorum at the Washington Federal special meeting. Abstentions will be counted as shares present and entitled to vote at the special meeting for purposes of determining the existence of a quorum. In the event a quorum is not present at the Washington Federal special meeting, it is expected that the Washington Federal special meeting will be adjourned or postponed.

Vote Required; Treatment of Abstentions; Broker Non-Votes and Failure to Vote

The Washington Federal share issuance proposal

Vote required: Approval of the Washington Federal share issuance proposal requires the affirmative vote, virtually or by proxy, of a majority of the votes cast at the Washington Federal special meeting. Approval of the Washington Federal share issuance proposal is a condition to the completion of the merger.

Effect of abstentions; broker non-votes and failure to vote: If you fail to submit a proxy or vote virtually at the Washington Federal special meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee with respect to the Washington Federal share issuance proposal, it will have no effect on such proposal.

38

##### Table of Contents

The Washington Federal adjournment proposal

Vote Required: Approval of the Washington Federal adjournment proposal requires the affirmative vote of the majority of the votes cast at the Washington Federal special meeting.

Effect of abstentions; broker non-votes and failure to vote: If you fail to submit a proxy or vote virtually at the Washington Federal meeting, mark “ABSTAIN” on your proxy or fail to instruct your bank, broker or other nominee with respect to the share issuance proposal, it will have no effect on such proposal.

As of the Washington Federal record date, the executive officers and directors of Washington Federal, as a group, held 1,307,158 shares of Washington Federal common stock, or approximately 1.99% of the outstanding Washington Federal common stock. While the executive officers and directors of Washington Federal have not entered into voting agreements agreeing to vote their shares of Washington Federal common stock in a particular manner, it is anticipated that the executive officers and directors of Washington Federal will vote consistent with the recommendation of the Washington Federal board, which is to vote “FOR” approval of the Washington Federal share issuance proposal.

Pursuant to the merger agreement, Washington Federal expects to issue a total of approximately 17,135,074 shares of Washington Federal common stock in connection with the consummation of the merger. Under the NASDAQ Listing Rules, a company listed on the NASDAQ is required to obtain shareholder approval prior to the issuance of common stock or securities convertible into or exercisable for common stock, in connection with the acquisition of stock of another company if the common stock has or will have upon issuance voting power equal to or in excess of 20% of the voting power outstanding before the issuance of stock or securities convertible into or exercisable for common stock, or the number of shares of common stock to be issued is or will be equal to or in excess of 20% of the number of shares of common stock outstanding before the issuance of the stock or securities. If the merger is completed, the number of shares of Washington Federal common stock issued will exceed 20% of the Washington Federal common stock outstanding before such issuance. In this proposal, Washington Federal is asking Washington Federal shareholders to authorize the issuance of Washington Federal common stock in connection with the merger.

After careful consideration, The Washington Federal board has determined that the share issuance pursuant to the merger agreement is in the best interests of Washington Federal and its shareholders and has unanimously approved the merger agreement, the merger and the other transactions contemplated by the merger agreement. See the section entitled “The Merger — Recommendation of the Washington Federal Board and Reasons of Washington Federal for the Merger” beginning on page 56.

The approval of the Washington Federal share issuance proposal is a condition to the completion of the merger.

The Washington Federal board has unanimously recommended that shareholders vote “FOR” approval of the Washington Federal share issuance proposal.

Proposal 2: The Washington Federal Adjournment Proposal

The Washington Federal special meeting may be adjourned or postponed, including for the purpose of soliciting additional proxies, if there are insufficient votes at the time of the Washington Federal special meeting to approve the Washington Federal share issuance proposal or if a quorum is not present at the Washington Federal special meeting. Other than an announcement to be made at the Washington Federal special meeting of the time, date and place of an adjourned meeting, an adjournment generally may be made without notice. Any adjournment or postponement of the Washington Federal special meeting for the purpose of soliciting additional proxies will allow the shareholders who have already sent in their proxies to revoke them at any time prior to their use at the Washington Federal special meeting as adjourned or postponed.

In this proposal, Washington Federal is asking Washington Federal shareholders to vote to approve to adjourn the Washington Federal special meeting to a later date or dates, if necessary, to permit further solicitation of proxies if there are not sufficient votes at the time of the Washington Federal special meeting to approve the Washington Federal share issuance proposal.

The Washington Federal board has unanimously recommended that shareholders vote “FOR” approval of the Washington Federal adjournment proposal.

Matters to Be Considered

At the Luther Burbank special meeting, Luther Burbank shareholders will be asked to consider and vote on the following proposals:

| • |  | the Luther Burbank merger proposal;

| • |  | the Luther Burbank compensation proposal; and

| • |  | the Luther Burbank adjournment proposal.

No other business may be conducted at the Luther Burbank special meeting. A copy of the merger agreement is included in this joint proxy statement/prospectus as Appendix A, and Luther Burbank shareholders are encouraged to read it carefully in its entirety.

Recommendation of the Luther Burbank Board

The Luther Burbank board has unanimously approved the merger agreement and the transactions contemplated by the merger agreement. Based on the Luther Burbank board’s reasons for approving the merger agreement described in this joint proxy statement/prospectus, the Luther Burbank board has determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are in the best interests of Luther Burbank and its shareholders and unanimously has recommended that Luther Burbank shareholders vote “FOR” approval of the Luther Burbank merger proposal. See the section entitled “The Merger — Recommendation of the Luther Burbank Board and Reasons of Luther Burbank for the Merger” beginning on page 73.

The Luther Burbank board has also unanimously recommended that Luther Burbank shareholders vote “FOR” approval of the Luther Burbank compensation proposal and “FOR” approval of the Luther Burbank adjournment proposal.

Shares Outstanding and Entitled to Vote; Luther Burbank Record Date

The close of business on March 23, 2023 has been fixed by Luther Burbank as the Luther Burbank record date for the determination of Luther Burbank shareholders entitled to notice of and to vote at the Luther Burbank special meeting and any adjournment or postponement of the Luther Burbank special meeting. At the close of business on the Luther Burbank record date, there were 51,103,710 shares of Luther Burbank common stock outstanding and

42

##### Table of Contents

entitled to vote, held by approximately 3,177 holders of record. Each share of Luther Burbank common stock entitles the holder to one vote at the Luther Burbank special meeting on all matters properly presented at the Luther Burbank special meeting.

Voting Your Shares of Luther Burbank Common Stock

Shareholders of Record

Luther Burbank shareholders of record may vote by mail, telephone, via the Internet or by attending the Luther Burbank special meeting and voting in person. If a Luther Burbank shareholder chooses to vote by mail, he or she should simply mark the enclosed proxy card, date and sign it, and return it in the postage paid envelope provided. Internet and telephone voting is available until 11:59 p.m., Eastern Time, on May 3, 2023.

Shares Held in “Street Name”

If a Luther Burbank shareholder’s shares of Luther Burbank common stock are held through a bank, broker or other nominee, such Luther Burbank shareholder is considered the beneficial owner of such shares held in “street name.” In such case, this joint proxy statement/prospectus has been forwarded by such Luther Burbank shareholder’s bank, broker or other nominee, who is considered, with respect to such shares, the shareholder of record. As the beneficial owner, a Luther Burbank shareholder has the right to direct such bank, broker or other nominee how to vote the shares by following the voting instructions that they have sent, or will send, to the Luther Burbank shareholder. Without specific instructions from the Luther Burbank shareholder, which will result in a broker non-vote, the bank, broker or other nominee is not empowered to vote a Luther Burbank shareholder’s shares on non-routine matters such as the Luther Burbank merger proposal, the Luther Burbank compensation proposal or the Luther Burbank adjournment proposal. Not voting these shares will have the effect of voting “AGAINST” the approval of the Luther Burbank merger proposal, but will not have any effect on the Luther Burbank compensation proposal (assuming a quorum is present) or the Luther Burbank adjournment proposal. When the vote is tabulated for the proposals, as described below, broker non-votes, if any, will not be counted for purposes of determining whether a quorum is present. Accordingly, we advise each Luther Burbank shareholder to promptly give instructions to his or her bank, broker or other nominee to vote “FOR” approval of the Luther Burbank merger proposal, “FOR” approval of the Luther Burbank compensation proposal and “FOR” approval of the Luther Burbank adjournment proposal. Alternatively, if a Luther Burbank shareholder is a beneficial owner and wishes to vote in person at the Luther Burbank special meeting, the Luther Burbank shareholder must provide a proxy executed in such Luther Burbank shareholder’s favor by the bank, broker or other nominee.

Revocation of Proxies

A Luther Burbank shareholder can revoke a proxy at any time before his or her shares are voted. If the Luther Burbank shareholder is a shareholder of record, the Luther Burbank shareholder can revoke a proxy by:

| • |  | delivering to Luther Burbank prior to the Luther Burbank special meeting a written notice of revocation addressed to Luther Burbank Corporation, 520 Third Street, 4th floor, Santa Rosa, CA 95401; Attention: Corporate Secretary;

| • |  | completing, signing and returning a new proxy card with a later date before the date of the Luther Burbank special meeting, which will automatically revoke any earlier dated proxy;

| • |  | calling the toll-free number listed on the Luther Burbank proxy card or by accessing the Internet site listed on the Luther Burbank proxy card to change his or her vote by 11:59 p.m., Eastern Time, on May 3, 2023, in which case the later submitted proxy via telephone or Internet, as the case may be, will be recorded and the earlier dated proxy revoked; or

43

##### Table of Contents

| • |  | attending the Luther Burbank special meeting and voting in person, which will automatically revoke any earlier dated proxy. However, simply attending the Luther Burbank special meeting without voting will not revoke a Luther Burbank proxy.

If a Luther Burbank shareholder has instructed a bank, broker or other nominee to vote such Luther Burbank shareholder’s shares of Luther Burbank common stock, the Luther Burbank shareholder must follow directions received from the bank, broker or other nominee to change his or her vote.

Voting of Proxies

Each executed proxy (including those given through voting by telephone or Internet) received by Luther Burbank before or at the Luther Burbank special meeting (and not revoked) by a holder of Luther Burbank common stock will be voted in accordance with the instructions indicated thereon. If no instructions are indicated on a properly executed proxy that is returned, such proxy will be voted “FOR” approval of the Luther Burbank merger proposal, “FOR” approval of the Luther Burbank compensation proposal and “FOR” approval of the Luther Burbank adjournment proposal.

Broker Non-Votes

A broker non-vote occurs when a bank, broker, trustee or other nominee is not permitted to vote on a “non-routine” matter without instructions from the beneficial owner of the shares and the beneficial owner fails to provide the bank, broker, trustee or other nominee with such instructions. Broker non-votes only count toward a quorum if at least one proposal is presented with respect to which the bank, broker, trustee or other nominee has discretionary authority. It is expected that all proposals to be voted on at the Luther Burbank special meeting will be “non-routine” matters, and, as such, broker non-votes, if any, will not be counted as present and entitled to vote for purposes of determining a quorum at the Luther Burbank special meeting. If your bank, broker, trustee or other nominee holds your shares of Luther Burbank common stock in “street name,” such entity will vote your shares of Luther Burbank common stock only if you provide instructions on how to vote by complying with the voter instruction form sent to you by your bank, broker, trustee or other nominee with this joint proxy statement/prospectus.

Quorum

A quorum, consisting of the holders of a majority of the shares entitled to vote at the Luther Burbank special meeting, must be present in person or represented by proxy before any action may be taken at the Luther Burbank special meeting. Once a share of Luther Burbank common stock is represented at the Luther Burbank special meeting, it will be counted for the purpose of determining a quorum not only at the Luther Burbank special meeting but also at any adjournment or postponement of the Luther Burbank special meeting. In the event that a quorum is not present at the Luther Burbank special meeting, it is expected that the Luther Burbank special meeting will be adjourned or postponed.

Abstentions of Luther Burbank common stock will be treated as represented and presented for quorum purposes.

Broker non-votes of Luther Burbank common stock and the failure to vote shares of Luther Burbank common stock by failing to return a properly executed proxy and failing to appear in person at the Luther Burbank special meeting, which is referred to as a failure to vote, will not be counted as present for purposes of establishing a quorum at the Luther Burbank special meeting and will not be voted on any of the proposals at the Luther Burbank special meeting.

44

##### Table of Contents

Vote Required; Treatment of Abstentions; Broker Non-Votes and Failure to Vote

The Merger Proposal

Vote required: Approval of the Luther Burbank merger proposal requires the affirmative vote of the holders of a majority of the outstanding shares of Luther Burbank common stock entitled to vote at the Luther Burbank special meeting. Approval of the Luther Burbank merger proposal is a condition to the completion of the merger.

Effect of abstentions; broker non-votes and failure to vote: If you fail to submit a proxy or vote in person at the Luther Burbank special meeting, mark “ABSTAIN” on your proxy or if you fail to instruct your bank, broker or other nominee (which we refer to as a broker non-vote) with respect to the merger proposal, it will have the same effect as a vote “AGAINST” the Luther Burbank merger proposal.

The Luther Burbank Compensation Proposal

Vote required: Approval of the Luther Burbank compensation proposal requires the affirmative vote of a majority of shares of Luther Burbank common stock entitled to vote represented in person or by proxy and voting at the Luther Burbank special meeting (assuming a quorum is present). Approval of the Luther Burbank compensation proposal is not a condition to the completion of the merger.

Effect of abstentions; broker non-votes and failure to vote: If you fail to submit a proxy or vote in person at the Luther Burbank special meeting, or fail to instruct your bank, broker or other nominee with respect to the compensation proposal, it will have no effect on such proposal (assuming a quorum if present). If you mark “ABSTAIN” on your proxy with respect to the compensation proposal, it will have the same effect as a vote “AGAINST” the compensation proposal.

The Luther Burbank compensation proposal is advisory, and therefore not binding on Luther Burbank, the Luther Burbank board’s compensation committee or the Luther Burbank board. Further, the arrangements are contractual in nature and not, by their terms, subject to Luther Burbank shareholder approval. Accordingly, regardless of the outcome of the Luther Burbank compensation proposal, if the merger is completed, Luther Burbank’s named executive officers may be or become entitled to receive the compensation that is based on or otherwise relates to the merger in accordance with the terms and conditions applicable to those payments.

The Luther Burbank Adjournment Proposal

Vote required: Approval of the Luther Burbank adjournment proposal requires the affirmative vote of a majority of shares of Luther Burbank common stock entitled to vote represented in person or by proxy and voting at the Luther Burbank special meeting.

Effect of abstentions; broker non-votes and failure to vote: If you fail to submit a proxy or vote in person at the Luther Burbank special meeting, or fail to instruct your bank, broker or other nominee with respect to the Luther Burbank adjournment proposal, it will have no effect on such proposal. If you mark “ABSTAIN” on your proxy with respect to the Luther Burbank adjournment proposal, it will have the same effect as a vote “AGAINST” the Luther Burbank adjournment proposal.

Shares of Luther Burbank Common Stock Subject to Shareholder Agreements

Each director and certain executive officers of Luther Burbank who own shares of Luther Burbank common stock, who collectively beneficially own in the aggregate approximately 23.19% of the outstanding shares of Luther Burbank common stock as of the Luther Burbank record date, have entered into the shareholder agreements with Washington Federal and Luther Burbank pursuant to which such shareholders have agreed to, among other things, to vote all shares of Luther Burbank common stock beneficially owned by him or her in favor of adoption and approval of the merger agreement and the merger and any other matters required to be

45

##### Table of Contents

approved for the consummation of the merger at any meeting of the shareholders of Luther Burbank, subject to certain conditions set forth therein. See the section entitled “The Merger — Shareholder Agreements” beginning on page 100.

The form of the shareholder agreement is included in this joint proxy statement/prospectus as Annex A to the merger agreement, which is attached as Appendix A to this joint proxy statement/prospectus.

Delivery of Proxy Materials

As permitted by applicable law, only one copy of this joint proxy statement/prospectus is being delivered to Luther Burbank shareholders residing at the same address, unless such Luther Burbank shareholders have notified Luther Burbank of their desire to receive multiple copies of the joint proxy statement/prospectus.

Luther Burbank will promptly deliver, upon oral or written request, a separate copy of the joint proxy statement/prospectus to any Luther Burbank shareholder residing at an address to which only one copy of such document was mailed.

Solicitation of Proxies

Luther Burbank will pay the costs of soliciting its shareholders’ proxies, as well as all other costs incurred by it in connection with the solicitation of proxies from its shareholders on behalf of the Luther Burbank board. In addition to solicitation by mail, directors, officers and employees of Luther Burbank may solicit proxies from shareholders of Luther Burbank in person or by telephone, facsimile or other electronic methods without compensation other than reimbursement for their actual expenses.

Arrangements also will be made with custodians, nominees and fiduciaries for the forwarding of solicitation material to the beneficial owners of stock held of record by such persons, and Luther Burbank will reimburse such custodians, nominees and fiduciaries for their reasonable out of pocket expenses in connection therewith.

Attending the Luther Burbank Special Meeting

All holders of Luther Burbank common stock, including holders of record and shareholders who hold their shares of Luther Burbank common stock through banks, brokers or other nominees are invited to attend the Luther Burbank special meeting. Shareholders of record can vote in person at the Luther Burbank 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 Luther Burbank special meeting. If you plan to attend the Luther Burbank 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.

Luther Burbank reserves the right to refuse admittance to anyone without proper proof of share ownership and without proper photo identification.

Adjournments and Postponements

You should read carefully this entire joint proxy statement/prospectus, including the merger agreement and the other documents included with this joint proxy statement/prospectus. A copy of the merger agreement is attached to this joint proxy statement/prospectus as Appendix A.

After careful consideration, the Luther Burbank board has determined that the merger, the merger agreement and the transactions contemplated by the merger agreement are in the best interests of Luther Burbank and its shareholders and has unanimously approved the merger agreement, the merger and the other transactions contemplated by the merger agreement. See the section entitled “The Merger — Recommendation of the Luther Burbank Board and Reasons of Luther Burbank for the Merger” beginning on page 73.

The approval of the Luther Burbank merger proposal is a condition to the completion of the merger.

The Luther Burbank board has unanimously recommended that shareholders vote “FOR” approval of the Luther Burbank merger proposal.

Proposal 2: The Luther Burbank Compensation Proposal

Pursuant to Section 14A of the Exchange Act and Rule 14a-21(c) thereunder, Luther Burbank is seeking a non-binding, advisory shareholder approval of the compensation that certain named executive officers of Luther Burbank may receive that is based on or otherwise relates to the merger as disclosed under “The Merger — Interests of Certain Luther Burbank Officers and Directors in the Merger — Golden Parachute Compensation.” The proposal gives Luther Burbank shareholders the opportunity to express their views on the merger-related compensation of Luther Burbank’s named executive officers.

Accordingly, Luther Burbank is asking Luther Burbank shareholders to vote “FOR” 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 Luther Burbank 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 “The Merger — Interests of Certain Luther Burbank Officers and Directors in the Merger — Golden Parachute Compensation” are hereby APPROVED.”

The Luther Burbank compensation proposal is advisory, and therefore not binding on Luther Burbank, the Luther Burbank board’s compensation committee or the Luther Burbank board. Further, the arrangements are contractual in nature and not, by their terms, subject to Luther Burbank shareholder approval. Accordingly, regardless of the outcome of the compensation proposal, if the merger is completed, Luther Burbank’s named executive officers may be or become entitled to receive the compensation that is based on or otherwise relates to the merger in accordance with the terms and conditions applicable to those payments.

The Luther Burbank board has unanimously recommended that shareholders vote “FOR” approval of the Luther Burbank compensation proposal.

As part of Luther Burbank’s continuous efforts to strengthen its business, increase value for shareholders and deliver superior loan and deposit products and services to its customers and communities it serves, the Luther Burbank board, in consultation with Luther Burbank senior management and, from time to time, with outside advisors, regularly reviews and considers Luther Burbank’s business plans and its basic strategic options, including organic growth, potential acquisitions of other financial institutions by Luther Burbank, mergers of equals and acquisitions of Luther Burbank. These strategic discussions have been set against a backdrop of, among other things, business performance as well as prospects and developments in the financial services industry, regulatory and compliance environments, the economy generally and financial markets, and the implications of such developments for financial institutions generally and for Luther Burbank, in particular. These reviews have also included assessments of ongoing consolidation in the financial services industry and the benefits and risks to Luther Burbank and its shareholders of strategic combinations compared to the benefits and risks of continued operation as a standalone company, all with the goal of enhancing shareholder value.

Ms. Lagomarsino, Luther Burbank’s President and Chief Executive Officer, and Mr. Beardall, Washington Federal’s President and Chief Executive Officer, were introduced at a conference in Carlsbad, California on March 8, 2022. During this introductory meeting, Ms. Lagomarsino and Mr. Beardall discussed, among other things, the pace of technological innovations in the banking industry and the history and culture of their respective organizations, recognizing the historical similarities. Ms. Lagomarsino and Mr. Beardall agreed to remain in contact, and to continue to get to know more about each other’s respective organizations. They did not make any definitive plans for future meetings. During the meeting on March 8, 2022, the parties did not discuss the terms of any potential strategic transaction.

During the ensuing months, and consistent with past practices, Ms. Lagomarsino participated in various conversations with executives from other financial institutions as well as financial advisors known to work with financial institutions regarding potential strategic opportunities for Luther Burbank. The perception among these parties, generally, was that Luther Burbank was not a particularly attractive strategic partner because of its relatively high-cost deposit base, liability-sensitive balance sheet and unique and limited loan and deposit product and service offerings. During this same period, Ms. Lagomarsino periodically communicated with Mr. Beardall on an informal basis regarding their respective organizations’ earnings announcements, general economic conditions, the financial services industry, and market trends. Neither Ms. Lagomarsino nor Mr. Beardall mentioned or otherwise discussed the terms or specifics of a potential strategic transaction between Luther Burbank and Washington Federal during these communications.

On September 16, 2022, in anticipation of a scheduled in-person meeting with Ms. Lagomarsino in Los Angeles, California on September 23, 2022, Mr. Beardall presented Ms. Lagomarsino with a broad outline for a potential strategic transaction between their respective institutions, which did not specifically address any proposed transaction consideration. During the September 23, 2022 meeting, Ms. Lagomarsino and Mr. Beardall discussed preliminarily a potential strategic transaction between their respective institutions. Mr. Beardall noted the strategic benefit for Washington Federal of entering into California, leveraging the Luther Burbank reputation and in-depth market knowledge to expand Washington Federal’s more diversified product offerings into California. Ms. Lagomarsino noted the strategic benefit for Luther Burbank of partnering with an institution like Washington Federal that had evolved its balance sheet and operations away from a thrift model very similar to Luther Burbank’s and into a diversified commercial bank. On a preliminary basis, the parties discussed a few specific terms of a potential transaction, after which both Ms. Lagomarsino and Mr. Beardall concluded that the meeting was sufficiently productive that it would be appropriate to invite the Luther Burbank board Chair, Mr. Trione, to join them in a follow up meeting.

On October 5, 2022, Ms. Lagomarsino and Mr. Trione met with Mr. Beardall in Seattle, Washington. At this meeting, Messrs. Trione and Beardall and Ms. Lagomarsino discussed, among other things, Mr. Beardall’s views on the banking industry’s outlook, his operating philosophy, and Washington Federal’s technology innovation initiatives. They also discussed the history of Washington Federal, and how Washington Federal was transformed from a thrift-like structure into a commercial bank. Although the participants discussed the potential benefits of a strategic transaction, as well as the potential risks, they did not discuss any terms of a potential transaction. Following this meeting, Ms. Lagomarsino and Mr. Trione determined that the discussion was sufficiently positive so as to warrant informing the Luther Burbank board of their discussion with Mr. Beardall regarding a potential strategic transaction with Washington Federal.

On October 7, 2022, the Washington Federal board held a special meeting via videoconference at which Mr. Beardall reported to the Washington Federal board on the discussions with Ms. Lagomarsino and the possibility of a strategic transaction with Luther Burbank. Mr. Beardall provided an overview of Luther Burbank and shared his observations regarding the strategic rationale for the transaction and potential benefits. Mr. Beardall also reviewed a draft non-binding term sheet to present to Luther Burbank that contained the contemplated proposed material terms of such a transaction. The potential terms included an acquisition of Luther Burbank by Washington Federal in an all-stock merger transaction in which Luther Burbank shareholders would receive shares of Washington Federal common stock as merger consideration at an undefined fixed

52

##### Table of Contents

exchange ratio to be set prior to announcement, but with an anticipated value of a 15% premium to Luther Burbank’s common stock trading price. The draft non-binding term sheet also provided that two representatives of Luther Burbank would be added to the Washington Federal board, although no specific individuals were identified for these board seats. In addition, the draft non-binding term sheet further provided that the parties would separately enter into an exclusivity agreement that would prohibit Luther Burbank or its officers, directors or representatives or advisors from soliciting proposals or entering into discussions with any other party relating to a possible acquisition of Luther Burbank so as to allow the parties sufficient time to conduct due diligence and negotiate a definitive agreement. Following these discussions, the Washington Federal board authorized Mr. Beardall to continue discussions with Luther Burbank regarding a possible strategic transaction and to take such other steps Washington Federal management deemed necessary or appropriate in furtherance of such discussions, including presenting to Luther Burbank a non-binding term sheet and exclusivity agreement on substantially the terms presented to the Washington Federal board.

On October 10, 2022, Luther Burbank and Washington Federal entered into a mutual non-disclosure agreement in order to facilitate the mutual exchange of certain business and financial information by each party. Promptly after entering into the mutual non-disclosure agreement, each party made available to representatives of the other party its respective due diligence materials in an electronic data room.

On October 13, 2022, Washington Federal submitted to Luther Burbank a draft non-binding term sheet. The potential terms included an acquisition of Luther Burbank by Washington Federal in an all-stock merger transaction in which Luther Burbank shareholders would receive shares of Washington Federal common stock as merger consideration at an undefined fixed exchange ratio to be set prior to announcement, but with an anticipated value of a 15% premium to Luther Burbank’s common stock trading price. The draft non-binding term sheet also provided that two representatives of Luther Burbank would be added to the Washington Federal board, although no specific individuals were identified for these board seats. In addition, the draft non-binding term sheet further provided that the parties would separately enter into an exclusivity agreement that would prohibit Luther Burbank or its officers, directors or representatives or advisors from soliciting proposals or entering into discussions with any other party relating to a possible acquisition of Luther Burbank so as to allow the parties sufficient time to conduct due diligence and negotiate a definitive agreement.

Commencing immediately after the parties entered into the mutual exclusivity agreement and extending through mid-November 2022, representatives of Luther Burbank and Washington Federal held numerous virtual, telephonic and in-person meetings focused on diligence topics covering a number of operational and functional areas. In addition to participating in due diligence sessions and having in-person meetings with members of the other party’s senior management, throughout October and November 2022, Ms. Lagomarsino and Mr. Beardall continued to engage in discussions about potential valuation terms and the other potential terms of the proposed transaction.

Recommendation of the Washington Federal Board and Reasons of Washington Federal for the Merger

After careful consideration, at a meeting held on November 13, 2022, the Washington Federal board unanimously determined that the merger agreement, including the merger and the other transactions, including the issuance of additional shares of Washington Federal common stock, contemplated thereby, is in the best interests of Washington Federal and its shareholders.

agreement, the merger and the other transactions, including the issuance of additional shares of Washington Federal common stock, contemplated by the merger agreement in consultation with Washington Federal management, as well as Washington Federal’s outside financial and legal advisors, and considered a number of factors, including the following material factors:

| • |  | its belief that the merger will result in a stronger commercial banking franchise with a diversified revenue stream, strong capital ratios, a well-balanced loan portfolio and an attractive funding base that has the potential to deliver enhanced value to Washington Federal’s shareholders;

| • |  | its understanding of Luther Burbank’s business, operations, regulatory and financial condition, asset quality, earnings, capital and prospects taking into account publicly available information and information furnished by Luther Burbank;

| • |  | its belief that the two companies share a common vision of the importance of customer service and local decision-making and that management and employees of Luther Burbank and Washington Federal possess complementary skills and expertise, which it believes should facilitate integration and implementation of the transaction;

| • |  | the anticipated pro forma financial impact of the merger on Washington Federal, including potential synergies, and the expected impact on financial metrics such as earnings and regulatory capital levels;

| • |  | the benefits to Washington Federal and its customers of operating as a larger organization, including enhancements in products and services, higher lending limits, and greater financial resources;

| • |  | the opportunity for Washington Federal to enter the California market in a meaningful way and expand and strengthen its presence in the West without generating substantial amounts of goodwill that would dilute shareholders;

| • |  | the shareholder agreements, as more fully described below under “The Merger – Shareholder Agreements” beginning on page 100;

| • |  | the increasing importance of operational scale and financial resources in maintaining efficiency and remaining competitive over the long term and in being able to capitalize on technological developments which significantly impact industry competitive conditions;

| • |  | the expected social and economic impact of the merger on the constituencies served by Washington Federal, including its borrowers, customers, depositors, employees, suppliers and communities;

| • |  | the opinion, dated November 13, 2022, of KBW to the Washington Federal board as to the fairness, from a financial point of view and as of the date of the opinion, to Washington Federal of the exchange ratio in the merger, as more fully described below under the section entitled “The Merger – Opinion of Washington Federal’s Financial Advisor” beginning on page 58; and

| • |  | Washington Federal’s review with Washington Federal’s outside legal advisor, DWT, of the material terms of the merger agreement, including the transaction structure, the amount and type of consideration to be paid, the terms related to a change in the Luther Burbank board’s recommendation to its shareholders, and the terms related to termination of the merger agreement, including the circumstances in which Washington Federal would be entitled to receive a termination fee from Luther Burbank, and regulatory approvals for the transaction.

The Washington Federal board also considered a number of potential risks and uncertainties associated with the merger in connection with its deliberation of the proposed transaction, including, without limitation, the following:

| • |  | the potential risk of diverting management attention and resources from the operation of Washington Federal’s business and towards the completion of the merger;

| • |  | the potential risks associated with achieving anticipated cost savings and successfully integrating Luther Burbank’s business, operations and workforce with those of Washington Federal;

57

##### Table of Contents

| • |  | the merger-related costs;

| • |  | the fact that, while Washington Federal expects that the merger will be consummated, there can be no assurance that all conditions to the parties’ obligations to complete the merger agreement will be satisfied, including the risk that necessary regulatory approvals of the merger and the bank merger, the Washington Federal shareholder approval of the share issuance or the Luther Burbank shareholder approval of the merger agreement and the merger might not be obtained and, as a result, the merger may not be consummated;

| • |  | the possibility that the anticipated benefits of the transaction will not be realized when expected or at all, including as a result of the impact of, or challenges arising from, the integration of the two companies or as a result of the strength of the economy, general market conditions and competitive factors in the areas where Washington Federal and Luther Burbank operate their respective businesses;

| • |  | the possibility that the fair value of the assets held by each of Luther Burbank and Washington Federal as a result of the merger may be affected negatively in the event of adverse changes in interest rates, which would reduce or eliminate the anticipated benefits of the merger for Washington Federal shareholders;

| • |  | the risk of potential employee attrition and/or adverse effects on business and customer relationships as a result of the pending merger; and

| • |  | the other risks described under the sections entitled “Risk Factors” beginning on page 25 and “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 34.

The foregoing discussion of the information and factors considered by the Washington Federal board is not intended to be exhaustive, but includes the material factors considered by the Washington Federal board. In reaching its decision to approve the merger agreement, the merger and the other transactions contemplated by the merger agreement, the Washington Federal board did not quantify or assign any relative weights to the specific factors it considered, and individual directors may have given different weights to different factors. The Washington Federal board considered all these factors as a whole, and overall considered the factors to be favorable to, and to support, its determination.

The Washington Federal board unanimously approved the merger agreement and recommends that Washington Federal’s shareholders vote “FOR” approval of the Washington Federal share issuance proposal and “FOR” approval of the Washington Federal adjournment proposal.

This summary of the reasoning of the Washington Federal board and other information presented in this section is forward-looking in nature and, therefore, should be read in light of the factors discussed under the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 34.

Opinion of Washington Federal’s Financial Advisor

Washington Federal engaged KBW to render financial advisory and investment banking services to Washington Federal, including an opinion to the Washington Federal board as to the fairness, from a financial point of view, to Washington Federal of the exchange ratio in the proposed merger. Washington Federal 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 attended the meeting of the Washington Federal board held on November 13, 2022 at which the Washington Federal board evaluated the proposed merger. At this meeting, KBW reviewed the financial aspects of the proposed merger and rendered 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 such opinion, the exchange ratio in the proposed

##### Table of Contents

merger was fair, from a financial point of view, to Washington Federal. The Washington Federal 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 Appendix B 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 Washington Federal 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 Washington Federal. It did not address the underlying business decision of Washington Federal to engage in the merger or enter into the merger agreement or constitute a recommendation to the Washington Federal board in connection with the merger, and it does not constitute a recommendation to any holder of Washington Federal 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’, affiliates’ or other 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 Washington Federal and Luther Burbank and bearing upon the merger, including, among other things:

##### Table of Contents

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 Washington Federal and Luther Burbank;

| • |  | the assets and liabilities of Washington Federal and Luther Burbank;

| • |  | the nature and terms of certain other merger transactions and business combinations in the banking industry;

| • |  | a comparison of certain financial and stock market information of Washington Federal and Luther Burbank with similar information for certain other companies, the securities of which were publicly traded;

| • |  | publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management), as well as assumed long-term growth rates for Luther Burbank provided to KBW by Washington Federal management, all of which information was discussed with KBW by Washington Federal management and used and relied upon by KBW at the direction of such management and with the consent of the Washington Federal board;

| • |  | publicly available consensus “street estimates” of Washington Federal, as well as assumed long-term growth rates for Washington Federal provided to KBW by Washington Federal management, all of which information was discussed with KBW by Washington Federal management and used and relied upon by KBW at the direction of such management and with the consent of the Washington Federal board; and

| • |  | estimates regarding certain pro forma financial effects of the merger on Washington Federal (including, without limitation, the cost savings and related expenses expected to result or be derived from the merger) that were prepared by Washington Federal management, provided to and discussed with KBW by such management, and used and relied upon by KBW at the direction of such management and with the consent of the Washington Federal 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 that were held by the managements of Washington Federal and Luther Burbank regarding the past and current business operations, regulatory relations, financial condition and future prospects of Washington Federal and Luther Burbank 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 provided to or discussed with it 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 Washington Federal management as to the reasonableness and achievability of the publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management), the publicly available consensus “street estimates” of Washington Federal, the assumed long-term growth rates for Luther Burbank and Washington Federal, and the estimates regarding certain pro forma financial effects of the merger on Washington Federal (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 (as so adjusted in the case of the publicly available consensus “street estimates” of Luther Burbank) was reasonably prepared and represented, or in the case of the publicly available consensus “street estimates” of Washington Federal referred to above that such estimates were consistent with, the best currently available estimates and judgments of Washington Federal management and that the forecasts, projections and estimates reflected in such information would be realized in the amounts and in the time periods

estimated. The publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management), as well as the assumed long-term growth rates for Luther Burbank provided to KBW by Washington Federal management, all of which KBW was directed by such management to use, reflected differences from the forecasts and projections that were prepared by Luther Burbank and provided to Washington Federal. Accordingly, with the consent of Washington Federal, in rendering its opinion, KBW’s reliance upon Washington Federal management as to the reasonableness and achievability of such publicly available consensus “street estimates” of Luther Burbank (as so adjusted) and such assumed long-term growth rates for Luther Burbank included reliance upon the judgments, estimates and assessments of Washington Federal management with respect to such differences.

It is understood that the portion of the foregoing financial information of Washington Federal and Luther Burbank that was provided to KBW was not prepared with the expectation of public disclosure and that all of the foregoing financial information, including the publicly available consensus “street estimates” of Luther Burbank and Washington Federal, was based on numerous variables and assumptions that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions, and, in particular, the widespread disruption, extraordinary uncertainty and unusual volatility arising from global tensions and political unrest, economic uncertainty, inflation, and the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions) and, accordingly, actual results could vary significantly from those set forth in such information. KBW assumed, based on discussions with the management of Washington Federal and with the consent of the Washington Federal 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. Among other things, such information assumed that the ongoing COVID-19 pandemic could have an adverse impact on Washington Federal and Luther Burbank. 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 Washington Federal or Luther Burbank 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 Washington Federal’s consent, that the aggregate allowances for loan and lease losses for each of Washington Federal and Luther Burbank 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 Washington Federal or Luther Burbank, the collateral 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 Washington Federal or Luther Burbank 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. Such estimates are inherently subject to uncertainty and should not be taken as KBW’s view of the actual value of any companies or assets.

KBW assumed, in all respects material to its analyses:

| • |  | the merger and any related transactions (including, without limitation, the bank 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 its analyses, from the draft of the merger agreement reviewed by KBW and referred to above), with no adjustments to the exchange ratio and with no other consideration or payments in respect of Luther Burbank common stock;

| • |  | the representations and warranties of each party in the merger agreement and in all related documents referred to in the merger agreement were true and correct;

| • |  | 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;

61

##### Table of Contents

| • |  | 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 all conditions to the completion of the merger and any related transactions would be satisfied without any waivers or modifications to the merger agreement or any of the related documents; and

| • |  | in the course of obtaining the necessary regulatory, contractual, or other consents or approvals for the merger and any related transactions, 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 Washington Federal, Luther Burbank 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 and the Exchange Act and all other applicable federal and state statutes, rules and regulations. KBW was further advised by representatives of Washington Federal that Washington Federal 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 Washington Federal, Luther Burbank, the merger and any related transaction (including the bank merger), 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 such opinion, of the exchange ratio in the merger to Washington Federal. 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 the bank merger), including without limitation, the form or structure of the merger or any such related transaction, any consequences of the merger or any related transaction to Washington Federal, its shareholders, creditors or otherwise, 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, any such related transaction, 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. There is currently significant volatility in the stock and other financial markets arising from global tensions and political unrest, economic uncertainty, inflation, and the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions. 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 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 Washington Federal 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 Washington Federal or the Washington Federal board;

| • |  | the fairness of the amount or nature of any compensation to any of Washington Federal’s officers, directors or employees, or any class of such persons, relative to any compensation to the holders of Washington Federal common stock or relative to the exchange ratio;

| • |  | 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 Washington Federal, Luther Burbank or any other party to any transaction contemplated by the merger agreement;

| • |  | the actual value of Washington Federal common stock to be issued in connection with the merger;

| • |  | the prices, trading range or volume at which Washington Federal common stock or Luther Burbank common stock would trade following the public announcement of the merger or the prices, trading range or volume at which Washington Federal common stock would trade following the consummation of the merger;

##### Table of Contents

| • |  | 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 Washington Federal, Luther Burbank, any of their respective shareholders, or relating to or arising out of or as a consequence of the merger or any other related transaction (including the bank merger), including whether or not the merger would qualify as a tax-free reorganization for U.S. 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, Washington Federal and Luther Burbank. 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, the KBW opinion was among several factors taken into consideration by the Washington Federal 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 Washington Federal 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 Washington Federal and Luther Burbank and the decision of Washington Federal to enter into the merger agreement was solely that of the Washington Federal board.

The following is a summary of the material financial analyses presented by KBW to the Washington Federal 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 Washington Federal 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 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.

For purposes of the financial analyses described below, KBW utilized an implied transaction value for the proposed merger of $12.53 per outstanding share of Luther Burbank common stock, or approximately $640.8 million in the aggregate, based on the 0.3353x exchange ratio in the proposed merger and the closing price of Washington Federal common stock on November 9, 2022. In addition to the financial analyses described below, KBW reviewed with the Washington Federal board for informational purposes, among other things, an implied transaction multiple for the proposed merger (based on the implied transaction value for the proposed merger of $12.53 per outstanding share of Luther Burbank common stock) of 14.5x Luther Burbank’s estimated 2023 earnings per share (“EPS”) assuming a September 30 fiscal year end using publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management).

Washington Federal Selected Companies Analysis (Group A). Using publicly available information, KBW compared the financial performance, financial condition and market performance of Washington Federal to seven selected major exchange-traded banks that were headquartered in the Western Region (defined as Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, New Mexico, Nevada, Oregon, Utah, Washington and Wyoming ) with total assets between $15 billion and $35 billion. Merger targets and ethnic-focused banks were excluded from the selected companies.

The selected companies were as follows (shown in descending order of total assets):

First Interstate BancSystem, Inc. Glacier Bancorp, Inc. First Hawaiian, Inc. Bank of Hawaii Corporation Pacific Premier Bancorp, Inc. Banner Corporation CVB Financial Corp.

To perform this analysis, KBW used profitability and other financial information for the most recent completed fiscal quarter (“MRQ”) or the latest 12 months (“LTM”) available (which, in all cases, were the periods ended September 30, 2022) or as of the end of such periods and market price information as of November 9, 2022. KBW also used fiscal year 2022 and 2023 EPS estimates taken from consensus “street” estimates for Washington Federal (which has a fiscal year end of September 30) and the selected companies (which have fiscal year ends of December 31). Where consolidated holding company level financial data for the selected companies was unreported, subsidiary bank level data was utilized to calculate ratios. Certain financial data presented in the tables below may not correspond to the data presented in Washington Federal’s historical financial statements, or the data presented under the section entitled “Opinion of Luther Burbank’s Financial Advisor” beginning on page 77, as a result of the different periods, assumptions and methods used by KBW to compute the financial data presented.

To perform this analysis, KBW used profitability and other financial information for the most recent completed fiscal quarter or the latest 12 months available (which, in all cases, were the periods ended September 30, 2022) or as of the end of such periods and market price information as of November 9, 2022. KBW also used fiscal year 2022 and 2023 earnings per share estimates taken from consensus “street” estimates for Luther Burbank and the selected companies (which have fiscal year ends of December 31 in all cases (including Luther Burbank) except for Kearny Financial Corp.) to the extent publicly available (consensus “street” estimates were not publicly available for one of the selected companies) and also consensus “street” estimates for Luther Burbank as adjusted by Washington Federal management. Where consolidated holding company level financial data for the selected companies was unreported, subsidiary bank level data was utilized to calculate ratios (subsidiary bank level data necessary to calculate Total Capital Ratio was also unreported for three of the selected companies). Certain financial data presented in the tables below may not correspond to the data presented in Luther Burbank’s historical financial statements, or the data presented under the section entitled “Opinion of Luther Burbank’s Financial Advisor” beginning on page 77, as a result of the different periods, assumptions and methods used by KBW to compute the financial data presented.

Selected Transactions Analysis. KBW reviewed publicly available information related to 11 selected U.S. bank mergers and acquisitions transactions announced since January 1, 2020 with a total announced transaction value between $500 million and $1 billion.

The selected transactions were as follows:

|  | Acquiror |  | Acquired Company |  |
|  | Simmons First National Corporation CBTX, Inc. Home Bancshares, Inc. SouthState Corporation United Community Banks, Inc. Glacier Bancorp, Inc. Eastern Bankshares, Inc. WSFS Financial Corporation SVB Financial Group Pacific Premier Bancorp, Inc. FB Financial Corporation |  | Spirit of Texas Bancshares, Inc. Allegiance Bancshares, Inc. Happy Bancshares, Inc. Atlantic Capital Bancshares, Inc. Reliant Bancorp, Inc. Altabancorp Century Bancorp, Inc. Bryn Mawr Bank Corporation Boston Private Financial Holdings, Inc. Opus Bank Franklin Financial Network, Inc. |  |

For each selected transaction, KBW derived the following implied transaction statistics, in each case based on the transaction consideration value paid for the acquired company and using financial data based on the acquired company’s then latest publicly available financial statements prior to the announcement of the respective transaction and publicly available one year LTM estimated EPS prior to the announcement of the respective transaction:

| • |  | Price per common share to tangible book value per share of the acquired company (in the case of selected transactions involving a private acquired company, this transaction statistic was calculated as total transaction consideration divided by total tangible common equity);

| • |  | Pay-to-Trade ratio (calculated as the price to tangible book value multiple paid in the respective transaction divided by the acquiror’s standalone closing stock price to tangible book value multiple);

##### Table of Contents

| • |  | Price per common share to LTM estimated EPS of the acquired company (in the case of selected transactions involving a private acquired company, this transaction statistic was calculated as total transaction consideration divided by LTM earnings); and

| • |  | Tangible equity premium to core deposits (total deposits less time deposits greater than $100,000) of the acquired company, referred to as core deposit premium.

KBW also reviewed the price per common share paid for the acquired company in the 10 selected transactions involving publicly traded acquired companies as a premium/(discount) to the closing price of the acquired company one day prior to the announcement of the respective transaction (expressed as a percentage and referred to as the one-day market premium). The above transaction statistics for the selected transactions were compared with the corresponding transaction statistics for the proposed merger based on the implied transaction value for the proposed merger of $12.53 per outstanding share of Luther Burbank common stock and using historical financial information for Luther Burbank as of or for the 12-month period ended September 30, 2022 and the closing price of Luther Burbank common stock on November 9, 2022.

The results of the analysis are set forth in the following (excluding the impact of the LTM EPS multiple for one of the selected transactions, which multiple was considered not meaningful because it was greater than 40.0x):

|  | Washington Federal / Luther Burbank |  |  | 25th Percentile |  |  | Median |  |  | Average |  |  | 75th Percentile |
Price / Tangible Book Value per Share |  |  | 0.95 | x |  |  | 1.50 | x |  |  | 1.62 | x |  |  | 1.75 | x |  |  | 1.82 | x

Price / LTM EPS |  |  | 7.2 | x |  |  | 12.3 | x |  |  | 13.7 | x |  |  | 16.2 | x |  |  | 19.1 | x
Core Deposit Premium |  |  | (0.8 | )% |  |  | 5.6 | % |  |  | 7.1 | % |  |  | 8.8 | % |  |  | 12.4 | %
One-Day Market Premium |  |  | 4.1 | % |  |  | 11.1 | % |  |  | 13.6 | % |  |  | 13.8 | % |  |  | 18.6 | %

No company or transaction used as a comparison in the above selected transaction analysis is identical to Luther Burbank or the proposed merger. 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 Washington Federal and Luther Burbank to various pro forma balance sheet and income statement items and the combined market capitalization of the combined entity. This analysis did not include purchase accounting adjustments or cost savings. To perform this analysis, KBW used (i) historical balance sheet data for Washington Federal and Luther Burbank as of September 30, 2022, (ii) publicly available consensus “street estimates” of Washington Federal, (iii) publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management) assuming a September 30 fiscal year end, and (iv) market price data as of November 9, 2022. 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 Washington Federal and Luther Burbank shareholders in the combined company based on the 0.3353x exchange ratio provided for in the merger agreement:

|  | Washington Federal % of Total |  |  | Luther Burbank % of Total |
Ownership at 0.3353x merger exchange ratio: |  |  | 79.2 | % |  |  | 20.8 | %
Pre-Transaction Market Capitalization: |  |  | 79.9 | % |  |  | 20.1 | %
Balance Sheet: |  |  |  |  |  |  |  |
Assets |  |  | 72.4 | % |  |  | 27.6 | %
Gross Loans Held for Investment (excl. PPP) |  |  | 70.4 | % |  |  | 29.6 | %

Pro Forma Financial Impact Analysis. KBW performed a pro forma financial impact analysis that combined projected income statement and balance sheet information of Washington Federal and Luther Burbank. Using (i) closing balance sheet estimates assumed as of June 30, 2023 for Washington Federal and Luther Burbank, extrapolated from historical data using growth rates as provided by Washington Federal management, (ii) publicly available consensus “street estimates” of Washington Federal, (iii) publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management) assuming a September 30 fiscal year end, and (iv) pro forma assumptions (including, without limitation, the cost savings and related expenses expected to result from the merger as well as certain purchase accounting adjustments and other merger-related adjustments and restructuring charges assumed with respect thereto) provided by Washington Federal 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 Washington Federal’s fiscal year 2024 estimated EPS and accretive to Washington Federal’s estimated tangible book value per share at closing assumed as of June 30, 2023. Furthermore, the analysis indicated that, pro forma for the merger, each of Washington Federal’s Tangible Common Equity to Tangible Assets, Leverage Ratio and Tier 1 Risk-Based Capital Ratio could be lower at closing assumed as of June 30, 2023, Washington Federal’s Common Equity Tier 1 Ratio could be higher at closing assumed as of June 30, 2023, and Washington Federal’s Total Risk-Based Capital Ratio could be approximately unchanged at closing assumed as of June 30, 2023. For all of the above analysis, the actual results achieved by Washington Federal following the merger may vary from the projected results, and the variations may be material.

Washington Federal Dividend Discount Model Analysis. KBW performed a dividend discount model analysis to estimate a range for the implied equity value of Washington Federal. In this analysis, KBW used publicly available consensus “street estimates” of Washington Federal and assumed Washington Federal long-term growth rates provided by Washington Federal management, and KBW assumed discount rates ranging from 10.0% to 14.0%. The range of values was derived by adding (i) the present value of the implied future excess capital available for dividends that Washington Federal could generate over the period from October 1, 2022 through September 30, 2027 and (ii) the present value of Washington Federal’s implied terminal value at the end of such period. KBW assumed that Washington Federal would maintain a tangible common equity to tangible assets ratio of 8.00% and Washington Federal would retain sufficient earnings to maintain that level. In calculating the terminal value of Washington Federal, KBW applied a range of 8.0x to 13.0x Washington Federal’s estimated fiscal year 2028 earnings. This dividend discount model analysis resulted in a range of implied values per share of Washington Federal common stock of $40.13 to $59.88, as compared to the closing price of Washington Federal common stock on November 9, 2022 of $37.36.

The dividend discount model 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, and discount rates. The analysis did not purport to be indicative of the actual values or expected values of Washington Federal or the pro forma combined company.

Luther Burbank Dividend Discount Model Analysis. KBW performed a dividend discount model analysis to estimate a range for the implied equity value of Luther Burbank, taking into account the cost savings expected to result from the merger. In this analysis, KBW used publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management), assumed Luther Burbank long-term growth rates provided by Washington Federal management and assumptions regarding cost savings expected to result from

72

##### Table of Contents

the merger provided by Washington Federal management, and KBW assumed discount rates ranging from 10.0% to 14.0%. The range of values was derived by adding (i) the present value of the implied future excess capital available for dividends that Luther Burbank could generate over the period from July 1, 2023 through September 30, 2027 and (ii) the present value of Luther Burbank’s implied terminal value at the end of such period, in each case applying estimated cost savings. KBW assumed that Luther Burbank would maintain a tangible common equity to tangible assets ratio of 8.00% and Luther Burbank would retain sufficient earnings to maintain that level. In calculating the terminal value of Luther Burbank, KBW applied a range of 8.0x to 13.0x Luther Burbank’s estimated fiscal year 2028 earnings (inclusive of estimated cost savings). This dividend discount model analysis resulted in a range of implied values per share of Luther Burbank common stock, taking into account the cost savings expected to result from the merger, of $9.75 to $16.74, as compared to the implied transaction value for the proposed merger of $12.53 per outstanding share of Luther Burbank common stock.

The dividend discount model 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, and discount rates. The analysis did not purport to be indicative of the actual values or expected values of Luther Burbank.

Miscellaneous. KBW acted as financial advisor to Washington Federal in connection with the proposed merger and did not act 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 an existing sales and trading relationship (i) between Washington Federal and each of KBW and a KBW broker-dealer affiliate and (ii) between Luther Burbank and a KBW broker-dealer affiliate), may from time to time purchase securities from, and sell securities to, Washington Federal and Luther Burbank. In addition, as market makers 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 Washington Federal or Luther Burbank 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, Washington Federal has agreed to pay KBW a total cash fee of $3,600,000, $1,000,000 of which became payable with the rendering of KBW’s opinion, and the balance of which is contingent upon the consummation of the merger. Washington Federal also agreed 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 KBW’s opinion, KBW provided investment banking and financial advisory services to Washington Federal and received compensation for such services. KBW acted as co-manager for Washington Federal’s February 2021 offering of preferred stock. In connection with such offering, KBW received aggregate fees (including underwriting discounts) of approximately $105,000 from Washington Federal. In the two years preceding the date of KBW’s opinion, KBW did not provide investment banking or financial advisory services to Luther Burbank. KBW may in the future provide investment banking and financial advisory services to Washington Federal or Luther Burbank and receive compensation for such services.

Recommendation of the Luther Burbank Board and Reasons of Luther Burbank for the Merger

After considering its strategic options and the factors discussed in this joint proxy statement/prospectus, the Luther Burbank board unanimously recommends approval of the merger agreement and the merger, determining that the merger, the merger agreement and the transactions contemplated by the merger agreement are in the best interests of Luther Burbank and its shareholders.

In evaluating the merger and the merger agreement, the Luther Burbank board consulted with Luther Burbank’s financial advisor, Piper Sandler, with respect to the financial aspects of the proposed sale, and

73

##### Table of Contents

consulted with Luther Burbank’s legal counsel, H&K, as to its legal duties and the terms of the merger agreement and related agreements. In reaching the conclusion to approve the merger and recommend approval of the merger agreement and the merger to the Luther Burbank shareholders, the Luther Burbank board considered a number of factors, including the following, without assigning any specific or relative weights to the factors and in no particular order:

| • |  | an extensive review of strategic options available to Luther Burbank and a thorough review of Washington Federal’s business, operations, financial condition, stock performance, asset quality, earnings and prospects, including the information obtained through due diligence;

| • |  | a review of the risks and prospects of Luther Burbank remaining independent, including (i) the challenges of the current interest rate environment and the effect of increasing rates on Luther Burbank’s liability sensitive balance sheet, particularly its effect on Luther Burbank’s net interest margin, capital and liquidity; (ii) the challenges of the current and prospective economic, regulatory and competitive environment facing the financial services industry generally, and Luther Burbank in particular, including the importance of scale in the continued rapid consolidation in the financial services industry; (iii) the additional risks associated with executing any of the options developed by Luther Burbank senior management to support a standalone strategy; (iv) the increasing costs associated with banking regulation, compliance and technology, generally; and (v) the anticipated costs of continuing to develop and enhance Luther Burbank’s business capabilities;

| • |  | the Luther Burbank board’s consideration that the transaction with Washington Federal was more favorable to holders of Luther Burbank common stock than the potential value that might result from other options reasonably available to Luther Burbank, including:

| • |  | the challenges facing Luther Burbank as an independent company and the Luther Burbank board’s belief that combining with a larger financial institution would benefit Luther Burbank’s shareholders;

| • |  | the fact that as of the date the Luther Burbank board determined to approve the merger and merger agreement, Luther Burbank’s senior management had recently contacted multiple financial institutions believed by Luther Burbank senior management to have a likelihood of having a serious interest in a business combination with Luther Burbank, and Luther Burbank did not receive any proposals in response; and

| • |  | the low probability of securing a more attractive proposal from another institution capable of consummating an acquisition of Luther Burbank;

| • |  | the exchange ratio and other financial terms of the merger and the merger agreement;

| • |  | the fact that the consideration that Luther Burbank’s shareholders will receive in the merger is in the form of a fixed exchange ratio of Washington Federal common stock and the fact that Luther Burbank shareholders would own approximately 21% of the combined company;

| • |  | the structure of the merger consideration as payable in shares of Washington Federal common stock, which will allow Luther Burbank shareholders to participate in the future performance of the combined company’s business and synergies resulting from the merger, including an expanded geographic footprint and an expansion and diversification of business lines;

| • |  | Washington Federal’s asset-sensitive interest rate risk profile and the opportunity to moderate Luther Burbank’s liability-sensitive interest rate risk profile, particularly in the prevailing and anticipated near- and medium-term interest rate environment;

| • |  | the potential for Luther Burbank’s shareholders to participate in the future earnings and growth of the combined company, including the potential challenges for Luther Burbank as a result of the current interest rate environment as well as in achieving significant organic growth on a standalone basis given its existing business lines, capital base and its relative scale;

##### Table of Contents

| • |  | the fact that the merger agreement does not preclude a third party from making an unsolicited acquisition proposal to Luther Burbank and that, under certain circumstances more fully described under “The Merger Agreement — No Solicitation” beginning on page 114, Luther Burbank may furnish non-public information to, and enter into discussions with, such a third party regarding a qualifying acquisition proposal;

The Luther Burbank board also considered the potential risks related to the transaction. The Luther Burbank board concluded that the anticipated benefits of combining with Washington Federal were likely substantially to outweigh these risks. These potential risks included:

| • |  | the potential risks associated with successfully integrating Luther Burbank’s business, operations and workforce with those of Washington Federal, including the costs of successfully integrating the two companies;

| • |  | the potential risks associated with Washington Federal entering the California market, within which Washington Federal has limited operating history;

| • |  | the potential for diversion of management and employee attention, and for employee attrition, during the period following the announcement of the merger and prior to the completion of the merger, and the potential effect on Luther Burbank’s business and relations with customers, service providers and other stakeholders, whether or not the merger is completed;

| • |  | the potential reaction of Luther Burbank’s customers to the proposed merger with WaFd Bank;

| • |  | the merger agreement provisions generally requiring Luther Burbank to conduct its business in the ordinary and usual course consistent with past practice and the other restrictions on the conduct of Luther Burbank’s business prior to the completion of the merger, which may delay or prevent Luther Burbank from undertaking business opportunities that may arise pending the completion of the merger;

The foregoing discussion of the information and factors considered by the Luther Burbank board is not intended to be exhaustive, but Luther Burbank believes that it includes the material factors considered by the Luther Burbank board in reaching its determination and recommendation. In view of the wide variety of factors considered by the Luther Burbank board in connection with its evaluation of the merger and the complexity of these matters, the Luther Burbank board did not attempt to quantify, rank or otherwise assign relative weights to specific factors that it considered in reaching its decision. Furthermore, in considering the factors described above, individual members of the Luther Burbank board may have given different weights to different factors.

In considering the recommendation of the Luther Burbank board, you should be aware that certain directors and executive officers of Luther Burbank may have interests in the merger that are different from, or in addition to, interests of shareholders of Luther Burbank generally and may create potential conflicts of interest. The Luther Burbank 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 Luther Burbank’s shareholders that they vote in favor of the merger proposal. See the section entitled “The Merger — Interests of Certain Luther Burbank Officers and Directors in the Merger” beginning on page 91.

The foregoing discussion of the information and factors considered by the Luther Burbank board is forward-looking in nature. This information should be read in light of the factors described under the section entitled “Cautionary Statement Regarding Forward-Looking Statements” beginning on page 34.

On the basis of these considerations, the Luther Burbank board unanimously approved the merger agreement and the transactions contemplated thereby and recommends that Luther Burbank’s shareholders vote “FOR” approval of the Luther Burbank merger proposal, “FOR” approval of the Luther Burbank compensation proposal and “FOR” approval of the Luther Burbank adjournment proposal.

Opinion of Luther Burbank’s Financial Advisor

Luther Burbank retained Piper Sandler to act as financial advisor to the Luther Burbank board in connection with Luther Burbank’s consideration of a possible business combination. Luther Burbank selected Piper Sandler to act as its financial advisor because Piper Sandler is a nationally recognized investment banking firm whose principal business specialty is financial institutions. In the ordinary course of its investment banking business, Piper Sandler is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions.

Piper Sandler acted as financial advisor to the Luther Burbank board in connection with the proposed merger and participated in certain of the negotiations leading to the execution of the merger agreement. At the November 13, 2022 meeting at which the Luther Burbank board considered the merger and the merger agreement, Piper Sandler delivered to the Luther Burbank board its oral opinion, which was subsequently confirmed in writing, to the effect that, as of such date, the exchange ratio was fair to the holders of Luther Burbank’s common stock from a financial point of view. The full text of Piper Sandler’s opinion is attached as Appendix C to this joint proxy statement/prospectus. The opinion outlines the procedures followed, assumptions made, matters considered and qualifications and limitations on the review undertaken by Piper Sandler in rendering its opinion. The description of the opinion set forth below is qualified in its entirety by reference to the full text of the opinion. Holders of Luther Burbank common stock are urged to read the entire opinion carefully in connection with their consideration of the proposed merger.

##### Table of Contents

Piper Sandler’s opinion was directed to the Luther Burbank board in connection with its consideration of the merger and the merger agreement and does not constitute a recommendation to any shareholder of Luther Burbank as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the merger and the merger agreement. Piper Sandler’s opinion was directed only to the fairness, from a financial point of view, of the exchange ratio to the holders of Luther Burbank common stock and did not address the underlying business decision of Luther Burbank to engage in the merger, the form or structure of the merger or any other transactions contemplated in the merger agreement, the relative merits of the merger as compared to any other alternative transactions or business strategies that might exist for Luther Burbank or the effect of any other transaction in which Luther Burbank might engage. Piper Sandler also did not express any opinion as to the fairness of the amount or nature of the compensation to be received in the merger by any officer, director or employee of Luther Burbank or Washington Federal, or any class of such persons, if any, relative to the compensation to be received in the merger by any other shareholder. Piper Sandler’s opinion was approved by Piper Sandler’s fairness opinion committee.

| • |  | certain publicly available financial statements and other historical financial information of Luther Burbank that Piper Sandler deemed relevant;

| • |  | the pro forma financial impact of the merger on Washington Federal based on estimated net income for Luther Burbank for the fiscal years ending September 30, 2023 and September 30, 2024 with an estimated annual net income growth rate for Luther Burbank for the fiscal years ending September 30, 2025 through September 30, 2027, as well as certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, and certain adjustments for current expected credit losses (“CECL”) accounting standards, as provided by the senior management of Washington Federal;

| • |  | the current market environment generally and the banking environment in particular; and

| • |  | such other information, financial studies, analyses and investigations and financial, economic and market criteria as Piper Sandler considered relevant.

Piper Sandler also discussed with certain members of the senior management of Luther Burbank and its representatives the business, financial condition, results of operations and prospects of Luther Burbank and held similar discussions with certain members of the senior management of Washington Federal and its representatives regarding the business, financial condition, results of operations and prospects of Washington Federal.

In performing its review, Piper Sandler relied upon the accuracy and completeness of all of the financial and other information that was available from public sources, that was provided to Piper Sandler by Luther Burbank, Washington Federal or their respective representatives, or that was otherwise reviewed by Piper Sandler, and Piper Sandler assumed such accuracy and completeness for purposes of rendering its opinion without any independent verification or investigation. Piper Sandler relied on the assurances of the respective senior managements of Luther Burbank and Washington Federal that they were not aware of any facts or circumstances that would have made any of such information inaccurate or misleading in any respect material to Piper Sandler’s analyses. Piper Sandler was not asked to and did not undertake an independent verification of any such information and Piper Sandler did not assume any responsibility or liability for the accuracy or completeness thereof. Piper Sandler did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of Luther Burbank or Washington Federal, nor was Piper Sandler furnished with any such evaluations or appraisals. Piper Sandler rendered no opinion on, or evaluation of, the collectability of any assets or the future performance of any loans of Luther Burbank or Washington Federal. Piper Sandler did not make an independent evaluation of the adequacy of the allowance for loan losses of Luther Burbank or Washington Federal, or the combined entity after the merger, and Piper Sandler did not review any individual credit files relating to Luther Burbank or Washington Federal. Piper Sandler assumed, with Luther Burbank’s consent, that the respective allowances for loan losses for both Luther Burbank and Washington Federal were adequate to cover such losses and would be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used certain internal net income projections for Luther Burbank for the years ending December 31, 2022 through December 31, 2024, estimated net income for Luther Burbank for the twelve months ending September 30, 2025 assuming annualized net income for the quarter ended December 31, 2024 with an estimated annual net income growth rate for the years ending September 30, 2026 and September 30, 2027 and estimated dividends per share for the years ending December 31, 2023 through September 30, 2027, as provided by the senior management of Luther Burbank. In addition, Piper Sandler used publicly available mean analyst net income estimates for Washington Federal for the fiscal years ending September 30, 2023 and September 30, 2024, as well as a long-term annual earnings per share growth rate for the fiscal years ending September 30, 2025 through September 30, 2027 and estimated dividends per share for Washington Federal for the fiscal years ending September 30, 2023 through September 30, 2027, as provided by the senior management of Washington Federal. Piper Sandler also received and used in its pro forma analyses estimated net income for Luther Burbank for the fiscal years ending September 30, 2023 and September 30, 2024 with an estimated annual net income growth rate for Luther Burbank for the fiscal years ending September 30, 2025 through September 30, 2027, as well as certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, and certain adjustments for CECL accounting standards, as provided by the senior management of Washington Federal. With respect to the foregoing information, the respective senior managements of Luther Burbank and Washington Federal confirmed to Piper Sandler that such information reflected (or in the case of the publicly available analyst estimates referred to above, were consistent with) the best currently available projections, estimates and judgements of senior management as to the future financial performance of Luther Burbank and Washington Federal, respectively, and Piper Sandler assumed that the financial results reflected in such information would be achieved. Piper Sandler expressed no opinion as to such projections, estimates or judgements, or the assumptions on which they were based. Piper Sandler also assumed

79

##### Table of Contents

that there had been no material change in Luther Burbank’s or Washington Federal’s assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements made available to Piper Sandler. Piper Sandler assumed in all respects material to its analyses that Luther Burbank and Washington Federal would remain as going concerns for all periods relevant to its analyses.

Piper Sandler also assumed, with Luther Burbank’s consent, that (i) each of the parties to the merger agreement would comply in all material respects with all material terms and conditions of the merger agreement and all related agreements, that all of the representations and warranties contained in such agreements were true and correct in all material respects, that each of the parties to such agreements would perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements were not and would not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the merger, no delay, limitation, restriction or condition would be imposed that would have an adverse effect on Luther Burbank, Washington Federal, the merger or any related transactions, and (iii) the merger and any related transactions would be consummated in accordance with the terms of the merger agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with Luther Burbank’s consent, Piper Sandler relied upon the advice that Luther Burbank received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the merger and the other transactions contemplated by the merger agreement. Piper Sandler expressed no opinion as to any such matters.

Piper Sandler’s opinion was necessarily based on financial, regulatory, economic, market and other conditions as in effect on, and the information made available to Piper Sandler as of, the date thereof. Events occurring after the date thereof could materially affect Piper Sandler’s opinion. Piper Sandler has not undertaken to update, revise, reaffirm or withdraw its opinion or otherwise comment upon events occurring after the date thereof. Piper Sandler expressed no opinion as to the trading value of Luther Burbank common stock or Washington Federal common stock at any time or what the value of Washington Federal common stock would be once it is actually received by the holders of Luther Burbank common stock.

In rendering its opinion, Piper Sandler performed a variety of financial analyses. The summary below is not a complete description of all the analyses underlying Piper Sandler’s opinion or the presentation made by Piper Sandler to the Luther Burbank board, but is a summary of the material analyses performed and presented by Piper Sandler. The summary includes information presented in tabular format. In order to fully understand the financial analyses, these tables must be read together with the accompanying text. The tables alone do not constitute a complete description of the financial analyses. The preparation of a fairness opinion is a complex process involving subjective judgments as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances. The process, therefore, is not necessarily susceptible to a partial analysis or summary description. Piper Sandler believes that its analyses must be considered as a whole and that selecting portions of the factors and analyses to be considered without considering all factors and analyses, or attempting to ascribe relative weights to some or all such factors and analyses, could create an incomplete view of the evaluation process underlying its opinion. Also, no company included in Piper Sandler’s comparative analyses described below is identical to Luther Burbank or Washington Federal and no transaction is identical to the merger. Accordingly, an analysis of comparable companies or transactions involves complex considerations and judgments concerning differences in financial and operating characteristics of the companies and other factors that could affect the public trading values or transaction values, as the case may be, of Luther Burbank and Washington Federal and the companies to which they were compared. In arriving at its opinion, Piper Sandler did not attribute any particular weight to any analysis or factor that it considered. Rather, Piper Sandler made qualitative judgments as to the significance and relevance of each analysis and factor. Piper Sandler did not form an opinion as to whether any individual analysis or factor (positive or negative) considered in isolation supported or failed to support its opinion, rather, Piper Sandler made its determination as to the fairness of the exchange ratio to the holders of Luther Burbank common stock on the basis of its experience and professional judgment after considering the results of all its analyses taken as a whole.

##### Table of Contents

In performing its analyses, Piper Sandler also made numerous assumptions with respect to industry performance, business and economic conditions and various other matters, many of which cannot be predicted and are beyond the control of Luther Burbank, Washington Federal, and Piper Sandler. The analyses performed by Piper Sandler are not necessarily indicative of actual values or future results, both of which may be significantly more or less favorable than suggested by such analyses. Piper Sandler prepared its analyses solely for purposes of rendering its opinion and provided such analyses to the Luther Burbank board at its November 13, 2022 meeting. Estimates on the values of companies do not purport to be appraisals or necessarily reflect the prices at which companies or their securities may actually be sold. Such estimates are inherently subject to uncertainty and actual values may be materially different. Accordingly, Piper Sandler’s analyses do not necessarily reflect the value of Luther Burbank common stock or Washington Federal common stock or the prices at which Luther Burbank or Washington Federal common stock may be sold at any time. The analyses of Piper Sandler and its opinion were among a number of factors taken into consideration by the Luther Burbank board in making its determination to approve the merger agreement and the analyses described below should not be viewed as determinative of the decision of the Luther Burbank board with respect to the fairness of the exchange ratio.

Summary of Proposed Merger Consideration and Implied Transaction Metrics.

Piper Sandler reviewed the financial terms of the proposed merger. Pursuant to the terms of the merger agreement, at the effective time of the merger each share of Luther Burbank common stock issued and outstanding immediately prior to the effective time of the transaction, except for certain shares as set forth in the merger agreement, shall be converted into the right to receive 0.3353 of a share of Washington Federal common stock. Piper Sandler calculated an aggregate implied transaction value of approximately $654 million and an implied purchase price per share of $12.79 consisting of the implied value of 51,155,830 shares of Luther Burbank common stock and based on the closing price of Washington Federal common stock on November 11, 2022. Based upon financial information for Luther Burbank as of or for the last twelve months (“LTM”) ended September 30, 2022 and the closing price of Washington Federal common stock on November 11, 2022, Piper Sandler calculated the following implied transaction metrics:

Transaction Price Per Share / Tangible Book Value Per Share |  |  | 97 | %
Transaction Price Per Share / LTM Earnings |  |  | 7.3 | x
Transaction Price Per Share / Estimated 2023e Earnings(1) |  |  | 19.1 | x
Transaction Price Per Share / Estimated 2024e Earnings(1) |  |  | 22.1 | x
Core Deposit Premium(2) |  |  | (4.0 | )%
Market Premium as of November 11, 2022 |  |  | 3.2 | %

| (1) | Based on year-ended December 31 Luther Burbank management projections

| (2) | Core deposits defined as total deposits less time deposits with balances greater than $250,000

##### Table of Contents

September 30, 2027, as provided by the senior management of Luther Burbank. To approximate the terminal value of a share of Luther Burbank common stock at September 30, 2027, Piper Sandler applied price to 2027 earnings multiples ranging from 7.0x to 12.0x and multiples of September 30, 2027 tangible book value ranging from 90% to 130%. Piper Sandler selected these price to earnings and tangible book value multiples based on Piper Sandler’s review of, among other matters, the trading multiples of the Nationwide Luther Burbank Peer Group, which Piper Sandler deemed to be comparable to Luther Burbank. The terminal values were then discounted to present values using different discount rates ranging from 10.0% to 14.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Luther Burbank common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of Luther Burbank common stock of $4.18 to $7.83 when applying multiples of earnings and $8.25 to $13.75 when applying multiples of tangible book value.

Piper Sandler also considered and discussed with the Luther Burbank board how this analysis would be affected by changes in the underlying assumptions, including variations with respect to earnings. To illustrate this impact, Piper Sandler performed a similar analysis, assuming Luther Burbank’s earnings varied from 20% above projections to 20% below projections. This analysis resulted in the following range of per share values for Luther Burbank’s common stock, applying the price to 2027 earnings multiples range of 7.0x to 12.0x referred to above and a discount rate of 10.24%.

Piper Sandler also performed an analysis that estimated the net present value per share of Washington Federal common stock, assuming Washington Federal performed in accordance with publicly available mean analyst net income estimates for Washington Federal for the fiscal years ending September 30, 2023 and September 30, 2024, as well as a long-term annual earnings per share growth rate for the fiscal years ending September 30, 2025 through September 30, 2027 and estimated dividends per share for Washington Federal for the fiscal years ending September 30, 2023 through September 30, 2027, as provided by the senior management of Washington Federal. To approximate the terminal value of a share of Washington Federal common stock at September 30, 2027, Piper Sandler applied price to 2027 earnings multiples ranging from 9.0x to 14.0x and multiples of September 30, 2027 tangible book value ranging from 140% to 190%. Piper Sandler selected these price to earnings and tangible book value multiples based on Piper Sandler’s review of, among other matters, the trading multiples of the Washington Federal Peer Group, which Piper Sandler deemed to be comparable to Washington Federal. The terminal values were then discounted to present values using different discount rates ranging from 8.0% to 12.0%, which were chosen to reflect different assumptions regarding required rates of return of holders or prospective buyers of Washington Federal common stock. As illustrated in the following tables, the analysis indicated an imputed range of values per share of Washington Federal common stock of $27.56 to $48.80 when applying multiples of earnings and $37.38 to $59.05 when applying multiples of tangible book value.

Piper Sandler noted that the net present value analysis is a widely used valuation methodology, but the results of such methodology are highly dependent upon the numerous assumptions that must be made, and the results thereof are not necessarily indicative of actual values or future results.

The following tables describe the discount rate calculation for Luther Burbank common stock and Washington Federal common stock, respectively, prepared by Piper Sandler. In its normal course of business Piper Sandler employs the Kroll Cost of Capital Navigator and Bloomberg in determining an appropriate discount rate. The discount rate for Luther Burbank common stock equals the risk free rate, plus the equity risk premium, plus the size premium, plus the industry premium. The discount rate for Washington Federal common stock equals the risk free rate, plus the product of the 2-year beta for Washington Federal common stock and the equity risk premium, plus the size premium.

Pro Forma Transaction Analysis

Piper Sandler analyzed certain potential pro forma effects of the merger on Washington Federal assuming the transaction closes on June 30, 2023. Piper Sandler utilized the following information and assumptions: (a) certain net income projections for Luther Burbank for the fiscal years ending September 30, 2023 and September 30, 2024 as well as long-term annual net income growth rates for the fiscal years ending September 30, 2025 through September 30, 2027, as provided by the senior management of Washington Federal, (b) publicly available mean analyst net income estimates for Washington Federal for the fiscal years ending September 30, 2023 and September 30, 2024, as well as a long-term annual earnings per share growth rate for the fiscal years ending September 30, 2025 through September 30, 2027 and estimated dividends per share for Washington Federal for the fiscal years ending September 30, 2023 through September 30, 2027, as provided by the senior management of Washington Federal, and (c) certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, and certain adjustments for CECL accounting standards, as provided by the senior management of Washington Federal. The analysis indicated that the transaction could be accretive to Washington Federal’s estimated earnings per share (excluding one-time transaction costs and expenses) in the years ending 2024 through 2027 and accretive to Washington Federal’s estimated tangible book value per share at close.

##### Table of Contents

In connection with this analysis, Piper Sandler considered and discussed with the Luther Burbank board how the analysis would be affected by changes in the underlying assumptions, including the impact of final purchase accounting adjustments determined at the closing of the transaction, and noted that the actual results achieved by the combined company may vary from projected results and the variations may be material.

Piper Sandler’s Relationship

Piper Sandler is acting as Luther Burbank’s financial advisor in connection with the transaction and will receive a fee for such services, which fee is contingent upon the closing of the merger. Piper Sandler’s fee will be 1.10% of the aggregate transaction value, which at the date of announcement was approximately $8.94 million. Piper Sandler also received a $500,000 fee from Luther Burbank upon rendering its opinion, which opinion fee will be credited in full towards the transaction fee which will become payable to Piper Sandler upon closing of the merger. Luther Burbank has also agreed to indemnify Piper Sandler against certain claims and liabilities arising out of Piper Sandler’s engagement and to reimburse Piper Sandler for certain of its out-of-pocket expenses incurred in connection with Piper Sandler’s engagement.

Piper Sandler has not provided any other investment banking services to Luther Burbank in the two years preceding the date of its opinion, nor did Piper Sandler provide any investment banking services to Washington Federal in the two years preceding the date thereof. In the ordinary course of Piper Sandler’s business as a broker-dealer, Piper Sandler may purchase securities from and sell securities to Luther Burbank and Washington Federal. Piper Sandler may also actively trade the equity and debt securities of Luther Burbank and Washington Federal for its own account and for the accounts of its customers.

Interests of Certain Luther Burbank Officers and Directors in the Merger

When Luther Burbank shareholders are considering the recommendation of the Luther Burbank board with respect to approving the Luther Burbank merger proposal at the Luther Burbank special meeting, Luther Burbank shareholders should be aware that Luther Burbank directors and officers have interests in the merger as individuals that are in addition to, or different from, the interests of shareholders of Luther Burbank generally. The Luther Burbank board was aware of these factors and considered them, among other matters, in approving the merger agreement and the merger, and in recommending to shareholders that they vote for approval of the merger proposal. These interests are described below. For purposes of this disclosure, the named executive officers of Luther Burbank are Simone Lagomarsino, President and Chief Executive Officer; Laura Tarantino, Executive Vice President, Chief Financial Officer; and Tammy Mahoney, Executive Vice President, Chief Risk Officer.

Stock Ownership

The directors and executive officers of Luther Burbank, as a group, beneficially owned and had the power to vote as of the Luther Burbank record date, a total of 11,878,732 shares of Luther Burbank common stock, representing approximately 23.24% of the outstanding shares of Luther Burbank common stock as of that date. Substantially all of the shares of Luther Burbank common stock beneficially owned by the directors and executive officers of Luther Burbank are expected to be voted in favor of the merger agreement, subject to the terms of the shareholder agreements entered into by Washington Federal, Luther Burbank and each director and certain executive officers of Luther Burbank who own shares of Luther Burbank common stock. See the section entitled “The Merger — Shareholder Agreements” beginning on page 100. Each of these persons will receive the same merger consideration for their shares of Luther Burbank common stock as the other Luther Burbank shareholders.

Treatment of Luther Burbank Restricted Stock and Luther Burbank Restricted Stock Units

Each outstanding award of Luther Burbank restricted stock and Luther Burbank restricted stock units issued pursuant to the Luther Burbank Omnibus Plan to directors and any executive officers or any other individual who

91

##### Table of Contents

is not a continuing employee will automatically vest in full, effective as of the effective time of the merger. The shares of Luther Burbank restricted stock and Luther Burbank restricted stock units will be converted into, and will be cancelled in exchange for, the right to receive (i) a number of shares of Washington Federal common stock equal to the number of such shares of Luther Burbank restricted stock and Luther Burbank restricted stock units multiplied by the exchange ratio, provided that any fractional shares of Washington Federal common stock will receive cash in lieu of fractional shares of Washington Federal common stock, plus (ii) the amount in cash equal to the sum of any accrued dividends or dividend equivalents that are payable in cash, pursuant to the terms of the Luther Burbank restricted stock or Luther Burbank restricted stock units.

Each share of Luther Burbank restricted stock and each Luther Burbank restricted stock unit held by any executive officer or other individual who is a continuing employee, to the extent expressly assumed by Washington Federal, will automatically cease to represent a share of Luther Burbank restricted stock or Luther Burbank restricted stock units and will be substituted with an award of Washington Federal restricted stock or a Washington Federal restricted stock unit. The number of shares of Washington Federal common stock subject to each Washington Federal award will be equal to the product (rounded to the nearest whole number) of the number of shares of Luther Burbank common stock subject to Luther Burbank restricted stock or Luther Burbank restricted stock units immediately prior to the effective time of the merger multiplied by the exchange ratio.

Each share of Luther Burbank restricted stock and each Luther Burbank restricted stock unit held by any executive officer or other individual who is a continuing employee, to the extent not expressly assumed by Washington Federal, will automatically vest in full, effective as of the effective time of the merger, and such shares of Luther Burbank restricted stock and such Luther Burbank restricted stock units will be converted into, and will be cancelled in exchange for, the right to receive (i) a number of shares of Washington Federal common stock equal to the number of shares of Luther Burbank restricted stock or Luther Burbank restricted stock units multiplied by the exchange ratio, provided that any fractional shares of Washington Federal common stock will receive cash in lieu of fractional shares of Washington Federal Common Stock, plus (ii) the amount in cash equal to the sum of any accrued dividends or dividend equivalents that are payable in cash, pursuant to the terms of the Luther Burbank restricted stock or Luther Burbank restricted stock units.

For an estimate of the amounts that would be realized by each of the Luther Burbank’s named executive officers in respect of her unvested equity awards assuming such executive officers are not continuing employees at the effective time of the merger, see the section entitled “ — Golden Parachute Compensation” beginning on page 96. The estimated aggregate amount that would be realized by the four Luther Burbank executive officers who are not named executive officers, and who hold unvested Luther Burbank equity awards in respect of their unvested Luther Burbank equity awards, if such executive officers are not continuing employees and the merger were to be completed on January 31, 2023 is $541,047. The estimated aggregate amount that would be realized by Luther Burbank non-employee directors in respect of their unvested Luther Burbank equity awards if the merger were to be completed on January 31, 2023 is $374,477. The amounts in this paragraph are based on equity award holdings as of January 31, 2023 and were calculated based on a price per share of Luther Burbank common stock equal to $11.69 (the average closing market price of Luther Burbank common stock over the first five business days following the public announcement of the merger on November 13, 2022) and include dividend equivalent rights accrued on outstanding equity awards. These amounts do not attempt to forecast any additional equity grants, vesting or forfeitures that may occur prior to the closing of the merger. As a result of the foregoing assumptions, the actual amounts to be received by the Luther Burbank executive officers and directors may differ materially from the amounts discussed above and in the disclosure in the section entitled “ — Golden Parachute Compensation” beginning on page 96.

Appointment of the Luther Burbank Nominees to the Boards of Directors of Washington Federal and WaFd Bank

Pursuant to the terms of the merger agreement, Washington Federal has agreed that, effective as of the effective time of the merger, each of the Washington Federal board and the WaFd Bank board will be comprised

92

##### Table of Contents

of 12 members, including two new directors, who will be recommended by Luther Burbank and be agreeable to Washington Federal (Washington Federal’s consent will not be unreasonably withheld, conditioned or delayed). Each such individual will serve until the next annual meeting of shareholders of Washington Federal at which the class of directors to which such individual will be appointed is presented to shareholders for reelection. In the event such an individual is appointed to a class of Washington Federal directors that will be presented to Washington Federal’s shareholders for reelection at an annual meeting of shareholders of Washington Federal held within 24 months following the closing date of the merger, Washington Federal is required to include such individual on the list of nominees for director presented by the Washington Federal board and for which the Washington Federal board will solicit proxies at such annual meeting of shareholders of Washington Federal, to serve for the applicable term of such individual’s class of directors and until such individual’s successor will be duly elected and qualified, provided, that such nomination and solicitation would not violate the fiduciary duties of the members of the Washington Federal board. The two new directors recommended by Luther Burbank will be selected from the five current independent members of the Luther Burbank board who are eligible to serve as a member of the Washington Federal board. Washington Federal and Luther Burbank have not yet determined the two existing directors of the Luther Burbank board who will be appointed or elected to the Washington Federal board and the WaFd Bank board.

As a director of Washington Federal and WaFd Bank, the Luther Burbank nominees will be entitled to receive the same compensation as the current non-employee directors of Washington Federal and WaFd Bank. During 2022, non-employee directors received cash annual retainer fees in the amount of $105,000, for the Chairman, and $70,000, for each other non-employee director, plus stock awards valued at $85,019.

Payments Upon Termination or a Change in Control

Employment Agreements

Luther Burbank is party to employment agreements with each of Msses. Lagomarsino, Tarantino and Mahoney. Each of these agreements provides for severance benefits in the event of certain qualifying terminations of employment, including a termination following a change in control (such as the merger).

If Ms. Lagomarsino’s employment was terminated voluntarily by Ms. Lagomarsino for “good reason” or if Luther Burbank terminates her employment “without cause,” in either case during the one-year period following a change in control, then, in consideration for executing a general release of claims in favor of Luther Burbank, Ms. Lagomarsino would be entitled to: (i) a severance payment equal to 36 months of Ms. Lagomarsino’s base salary and target bonus (as then in effect), paid in equal installments for 36 months; (ii) a pro-rated bonus for the calendar year in which the termination occurs based on the number of days Ms. Lagomarsino was employed that year and the actual satisfaction of the performance conditions, paid at the time bonuses are paid to other participants; and (iii) full vesting of each outstanding award under the Luther Burbank Omnibus Plan that Luther Burbank granted to Ms. Lagomarsino. In addition, Luther Burbank will pay Ms. Lagomarsino, in 24 monthly installments, an amount equal to the monthly cost of COBRA continuation coverage under the applicable medical plan or plans at the date of termination, so long as she elects such continuation coverage. Ms. Lagomarsino’s employment agreement provides that any change in control benefits are subject to reduction to avoid the imposition of excise taxes under Section 4999 of the Code to the extent that she will be in a better net after-tax position as a result of such reduction.

If Ms. Tarantino’s employment was terminated voluntarily by Ms. Tarantino for “good reason” or Luther Burbank terminates her employment “without cause,” in either case during the one-year period following a change in control, then, in consideration for executing a general release of claims in favor of Luther Burbank, Ms. Tarantino would be entitled to: (i) a severance payment equal to 24 months of Ms. Tarantino’s base salary and target bonus (as then in effect), paid in equal installments for 24 months; and (ii) two times the target bonus for the calendar year in which the termination occurs, paid at the time bonuses are paid to other participants. Each outstanding award under the Luther Burbank Omnibus Plan that Luther Burbank granted to Ms. Tarantino

93

##### Table of Contents

will become fully vested. In addition, Luther Burbank will pay Ms. Tarantino, in 24 monthly installments, an amount equal to the monthly cost of COBRA continuation coverage under the applicable medical plan or plans at the date of termination, so long as she elects such continuation coverage. Ms. Tarantino’s employment agreement provides that any change in control benefits are subject to reduction to avoid the imposition of excise taxes under Section 4999 of the Code to the extent that she will be in a better net after-tax position as a result of such reduction.

If Ms. Mahoney’s employment was terminated voluntarily by Ms. Mahoney for “good reason” or Luther Burbank terminates her employment “without cause,” in either case during the one-year period following a change in control, then, in consideration for executing a general release of claims in favor of Luther Burbank, Ms. Mahoney would be entitled to a severance payment equal to 24 months of Ms. Mahoney’s base salary and the target bonus (as then in effect), paid in equal installments for 24 months. Each outstanding award under the Luther Burbank Omnibus Plan that Luther Burbank granted to Ms. Mahoney will become fully vested. In addition, Luther Burbank will pay Ms. Mahoney, in 18 monthly installments, an amount equal to the monthly cost of COBRA continuation coverage under the applicable medical plan or plans at the date of termination, so long as she elects such continuation coverage. Ms. Mahoney’s employment agreement provides that any change in control benefits are subject to reduction to avoid the imposition of excise taxes under Section 4999 of the Code to the extent that she will be in a better net after-tax position as a result of such reduction.

Executive Severance Plans

Luther Burbank maintains an executive severance and change in control plan (the “Change in Control Plan”), in which each of Messrs. Medhat, Stefani, Fanter and Smith participate. The Change in Control Plan provides for severance benefits in the event of certain qualifying terminations of employment, including a termination following a change in control (such as the merger).

Pursuant to the Change in Control Plan, the termination of a participant’s employment by Luther Burbank without “cause” or by the participant with “good reason” that occurs during the 12-month period following a change in control (including the merger) will entitle the participant to a severance payment equal to 24 months of the base salary, plus two times the participant’s target bonus, paid in equal monthly installments for 24 months. In addition, Luther Burbank will pay each executive, in 24 monthly installments, an amount equal to the monthly cost of COBRA continuation coverage under the applicable medical plan, or plans at the date of termination, so long as the participant elects such continuation coverage. The Change in Control Plan provides that any change in control benefits are subject to reduction to avoid the imposition of excise taxes under Section 4999 of the Code to the extent that the participant will be in a better net after-tax position as a result of such reduction.

Salary Continuation Agreements

LB Savings is a party to salary continuation agreements with each of Mr. Trione and Ms. Tarantino. Each agreement provides post-employment monthly retirement benefits or payments in the event of death or disability.

Pursuant to the salary continuation agreement with Mr. Trione, LB Savings will distribute an annual benefit equal to $318,400, payable in 12 monthly installments commencing on the first day of the month following his termination of employment. The annual benefit will be distributed to Mr. Trione for 20 years.

Pursuant to the salary continuation agreement with Ms. Tarantino, upon her termination of employment after reaching age 62 or due to a termination without cause or with good reason, LB Savings will distribute an annual benefit for a period of 20 years that is equal to 80% of her base salary for the year in which her termination of employment occurs, in 12 monthly installments commencing on the first day of the month following her termination of employment. This annual benefit is decreased if her termination of employment occurs prior to the date she reaches age 62 (unless such termination is due to a termination without cause or with good reason, or death). However, if her termination of employment is within 36 months following a change in control (such as the merger), her full benefit under the salary continuation agreement will be payable regardless of her age at the time of termination.

94

##### Table of Contents

Pursuant to the terms of the merger agreement, upon the effective time of the merger, Washington Federal will assume the salary continuation agreements with Mr. Trione and Ms. Tarantino.

For an estimate of the value of the severance payments and benefits that would be payable to each of the Luther Burbank named executive officers in connection with a qualifying termination, see the section entitled “— Golden Parachute Compensation” beginning on page 96. The estimated aggregate amount of severance payments and benefits that would be payable to the four Luther Burbank executive officers who are not named executive officers assuming a qualifying termination occurred on January 31, 2023 is $4,569,400. The estimated aggregate amount of payments that would be payable to Mr. Trione pursuant to his salary continuation agreement assuming a qualifying termination occurred on January 31, 2023 is $6.4 million.

Severance Program

Pursuant to the merger agreement, LB Savings has adopted a severance program (the “severance program”) applicable to LB Savings employees employed on a full-time basis on the effective date of the merger who are not subject to a severance program or contractually entitled to severance benefits. Employees who are terminated by LB Savings “without cause” 180 days prior to the effective time of the merger or within 180 days following the consummation of the merger, will be eligible for the severance program.

Severance under the severance program will be calculated using the current base salary; however, contingent compensation, commissions, bonuses, overtime, employer matching contributions to any retirement plans, “per file or unit” incentives and any other payments will not be included in the calculation of severance pay. Additionally, severance compensation is based on a general formula of two weeks of pay for every completed consecutive year of employment with LB Savings, paid as a lump sum, subject to minimums and maximums based on employment category, with the maximum severance offered under the severance program being six months of pay. In addition to severance pay, should eligible employees duly elect COBRA continuation coverage, LB Savings or WaFd, as applicable, will pay the cost of the month premium for such continuation coverage for the first two months of coverage.

New Employment Arrangement

On February 3, 2023, Tammy Mahoney, Executive Vice President and Chief Risk Officer at Luther Burbank, entered into an offer letter with Washington Federal that provides certain terms and conditions of her employment as Senior Vice President and Chief Risk Officer of Washington Federal following the completion of the merger. Ms. Mahoney’s employment will take effect at the completion of the merger and includes the following:

| • |  | an annual base salary of $360,000;

| • |  | a signing bonus, subject to forfeiture in certain circumstances, of $500,000;

| • |  | participation in the Washington Federal Short Term Incentive Bonus Program;

| • |  | a grant of Washington Federal restricted stock with a value of $2,000,000; and

| • |  | an agreement by Ms. Mahoney to waive all severance or change in control payments which she might otherwise be entitled to receive (for additional detail about such arrangements, see the section entitled “— Payments Upon Termination or a Change in Control” beginning on page 93 and see the section entitled “— Golden Parachute Compensation” beginning on page 96).

These provisions are subject to successful completion of a background check, the effectiveness of the waiver of the change in control payments described above and completion of the merger.

Other Interests

Prior to the effective time of the merger, Washington Federal may, in its discretion, initiate negotiations of agreements, arrangements and understandings with any of the Luther Burbank executive officers or directors regarding compensation or benefits and, either Luther Burbank or Washington Federal may enter into definitive agreements with, or provide additional compensation or benefits to, the Luther Burbank executive officers or directors. As of the date of this joint proxy statement/prospectus, other than as described above, no new agreements, arrangements or understandings regarding compensation or benefits with any of the Luther Burbank executive officers or directors have been agreed.

Golden Parachute Compensation

This section sets forth the information required by Item 402(t) of Regulation S-K regarding the compensation for each named executive officer of Luther Burbank that is based on or otherwise relates to the merger and that will or may become payable to each such named executive officer at the effective time or on a qualifying termination of employment in connection with the merger. The “golden parachute” compensation payable to these individuals is subject to a non-binding advisory vote of Luther Burbank shareholders, as described in more detail in the section entitled “Luther Burbank Proposals” beginning on page 48.

The estimated potential payments in the table below are based on the following assumptions:

| • |  | a merger closing on January 31, 2023 (the assumed date of the closing of the merger solely for purposes of this golden parachute compensation disclosure);

| • |  | each named executive officer will experience a qualifying termination at the effective time of the merger;

| • |  | a price per share of Luther Burbank common stock equal to $11.69, the average closing market price of Luther Burbank common stock over the first five business days following the public announcement of the merger on November 13, 2022; and

| • |  | base salary and equity award holdings as of January 31, 2023, excluding any dividends but including dividend equivalent rights accrued on outstanding equity awards.

Indemnification

Luther Burbank’s directors, officers and employees are entitled to continuing indemnification against certain liabilities by virtue of provisions contained in the Luther Burbank articles, the Luther Burbank bylaws, indemnity and employment agreements between Luther Burbank and certain of the officers of Luther Burbank and the merger agreement. Pursuant to the merger agreement, Washington Federal agreed for a period of six years from the closing of the merger, to indemnify and hold harmless each present and former director, officer and employee of Washington Federal or a subsidiary of Washington Federal, as applicable, determined as of the

97

##### Table of Contents

effective time of the merger, against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring, at or prior to the effective time of the merger, whether asserted or claimed prior to, at or after the effective time of the merger, arising in whole or in part out of or pertaining to the fact that he or she was a director, officer, employee, fiduciary or agent of Luther Burbank or any subsidiary of Luther Burbank or is or was serving at the request of Luther Burbank or any subsidiary of Luther Burbank as a director, officer, employee, fiduciary or agent of another corporation, partnership, joint venture, trust or other enterprise, including, without limitation, matters related to the negotiation, execution and performance of the merger agreement or consummation of the merger, to the fullest extent which the indemnified parties would be entitled under the Luther Burbank articles and the Luther Burbank bylaws or any agreement, arrangement or understanding which has been set forth in the merger agreement, in each case as in effect on the date of the merger agreement.

Pursuant to the merger agreement, Washington Federal has agreed to maintain Luther Burbank’s existing directors’ and officers’ liability insurance policy (or provide a policy providing comparable coverage and amounts on terms no less favorable to the persons currently covered by Luther Burbank’s existing policy, including Washington Federal’s existing policy if it meets the foregoing standard) covering persons who are currently covered by such insurance for a period of six years after the effective time of the merger, provided that if the cost of such insurance 300% of the annual premiums paid by Luther Burbank for its existing directors’ and officers’ liability insurance (the “maximum insurance amount”) Washington Federal will obtain what it reasonably determines to be the most advantageous coverage as is available for the maximum insurance amount.

Other than as set forth above, no director or officer of Luther Burbank has any direct or indirect material interest in the merger, except insofar as ownership of Luther Burbank common stock might be deemed such an interest.

Board of Directors and Officers of Washington Federal and WaFd Bank After the Merger

Except as described in the next sentence, the directors and officers of Washington Federal and WaFd Bank immediately prior to the effective time of the merger will be the directors and officers of Washington Federal and WaFd Bank following the merger until the earlier of their resignation or removal or until their respective successors are duly appointed and qualified. Pursuant to the terms of the merger agreement, Washington Federal has agreed that, effective as of the effective time of the merger, each of the Washington Federal board and the WaFd Bank board will be comprised of 12 members, including two new directors, who will be recommended by Luther Burbank and be agreeable to Washington Federal (Washington Federal’s consent will not be unreasonably withheld, conditioned or delayed). Each such individual will serve until the next annual meeting of shareholders of Washington Federal at which the class of directors to which such individual will be appointed is presented to shareholders for reelection. In the event such an individual is appointed to a class of Washington Federal directors that will be presented to Washington Federal’s shareholders for reelection at an annual meeting of shareholders of Washington Federal held within 24 months following the closing date of the merger, Washington Federal is required to include such individual on the list of nominees for director presented by the Washington Federal board and for which the Washington Federal board will solicit proxies at such annual meeting of shareholders of Washington Federal, to serve for the applicable term of such individual’s class of directors and until such individual’s successor will be duly elected and qualified, provided, that such nomination and solicitation would not violate the fiduciary duties of the members of the Washington Federal board. The two new directors recommended by Luther Burbank will be selected from the five current independent members of the Luther Burbank board who are eligible to serve as a member of the Washington Federal board. Washington Federal and Luther Burbank have not yet determined the two existing directors of the Luther Burbank board who will be appointed or elected to the Washington Federal board and the WaFd Bank board.

Regulatory Approvals Required for the Merger

The closing of the merger is conditioned upon the receipt of all approvals of regulatory authorities required for the merger and the bank merger. Under the terms of the merger agreement, Washington Federal and Luther Burbank have agreed to use their reasonable best efforts to obtain all necessary permits, consents, approvals and authorizations from any governmental authority necessary to consummate the merger and the bank merger.

Upon consummation of the merger, Washington Federal will merge its two resulting bank subsidiaries, LB Savings and WaFd Bank, with WaFd Bank as the surviving bank in the bank merger. In order to complete the transactions contemplated by the merger agreement, Washington Federal and Luther Burbank must first file all required regulatory notices and obtain all regulatory approvals, consents and orders required in connection with both the merger and the bank merger. In this regard, the parties must obtain the approval of the FDIC and the WDFI for the bank merger, provide notice of the bank merger to the CDFPI, obtain an order of exemption from the CDFPI for the merger, and provide notice of the merger to the FRBSF. Applications were filed with the FDIC on or about January 6, 2023 and the WDFI on or about January 9, 2023, and the notice to the CDFPI was filed on or about January 9, 2023. Washington Federal submitted the required notice to the FRBSF and the request for an exemption to the CDFPI on March 1, 2023. Pursuant to the exemption request, the CDFPI issued an order of exemption (approving the exemption request) on March 21, 2023. Finally, pursuant to the FDIC’s application processing guidelines set forth in 12 CFR Part 303, the agency requested additional information on the application on February 6, 2023. Pursuant to an extension granted by the FDIC, Washington Federal and Luther Burbank are working cooperatively to provide the requested information on or about April 7, 2023.

There can be no assurance as to whether all regulatory approvals will be obtained or as to the dates of the approvals. There also can be no assurance that the regulatory approvals received will not contain a condition or requirement that results in a failure to satisfy the conditions to closing set forth in the merger agreement. See the section entitled “The Merger Agreement — Conditions to Completion of the Merger” beginning on page 115.

Accounting Treatment of the Merger

The merger will be accounted for under the acquisition method of accounting under GAAP. Under this method, Luther Burbank’s assets and liabilities as of the date of the merger will be recorded at their respective fair values and added to those of Washington Federal. Any excess between the purchase price for Luther Burbank and the fair value of the identifiable net assets acquired (including core deposit intangibles) will be recorded as goodwill. In accordance with FASB Accounting Standards Codification (ASC) Topic 350, “Intangibles—Goodwill and Other,” the goodwill resulting from the merger will not be amortized to expense, but instead will be reviewed for impairment at least annually and to the extent goodwill is impaired, its carrying value will be written down to its implied fair value and a charge will be made to earnings. Core deposit intangibles with definite useful lives recorded by Washington Federal in connection with the merger will be amortized to expense or written down if earlier impairment indicators arise. The financial statements of Washington Federal issued after the merger will reflect the results attributable to the acquired operations of Luther Burbank beginning on the date of completion of the merger.

Stock Exchange Listings

Washington Federal’s common stock and Luther Burbank’s common stock are listed on the NASDAQ under the symbols “WAFD” and “LBC,” respectively. Upon completion of the merger, Luther Burbank common stock will be delisted from the NASDAQ, will be deregistered under the Exchange Act and will cease to be publicly traded.

Under the terms of the merger agreement, Washington Federal has agreed to use its reasonable best efforts to cause the shares of Washington Federal common stock to be issued to (i) Luther Burbank shareholders as the merger consideration, and (ii) in connection with the conversion of the unvested restricted shares of Luther Burbank common stock into shares of Washington Federal common stock in connection with the merger, to be

99

##### Table of Contents

approved for listing on the NASDAQ prior to the effective time of the merger. Following the merger, Washington Federal common stock will continue to be traded on the NASDAQ.

No Appraisal or Dissenters’ Rights in the Merger

Under the CGCL, shareholders are generally entitled to dissent from a merger or consolidation and obtain payment of the fair value of their shares when a merger or consolidation occurs. However, the CGCL provides that appraisal rights are not available for shares that are listed on a national securities exchange where the merger consideration is stock of a publicly traded corporation. Luther Burbank’s common stock is traded on a national security exchange and the merger consideration, comprised of Washington Federal’s common stock, is also traded on a national securities exchange. As such, Luther Burbank’s shareholders are not entitled to appraisal rights.

Shareholder Agreements

In connection with the execution of the merger agreement, each director and certain executive officers of Luther Burbank who own shares of Luther Burbank common stock, reflecting an aggregate of approximately 23.16% of the outstanding Luther Burbank common stock as of the date of the merger agreement, entered into the shareholder agreements with Luther Burbank and Washington Federal. The following summary of the shareholder agreements qualified in its entirety by reference to the form of shareholder agreement, a copy of which is attached as Annex A to the merger agreement, which is included in Appendix A to this joint proxy statement/prospectus.

Pursuant to the shareholder agreements, each director and executive officer party to the shareholder agreements has agreed, among other things, to:

| • |  | to appear at any meeting of the shareholder of Luther Burbank or to otherwise cause their shares to be counted as present at the meeting for purposes of calculating a quorum;

| • |  | vote (or cause to be voted), in person or by proxy, or deliver a written consent (or cause a consent to be delivered) covering, all shares of Luther Burbank common stock beneficially owned by the director and executive officer or as to which the director and executive officer has, directly or indirectly, the right to direct the voting:

| • |  | in favor of adoption and approval of the merger, the merger agreement and the transactions contemplated by the merger agreement;

| • |  | against any action or agreement that to the knowledge of each of the directors and executive officers would reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of Luther Burbank contained in the merger agreement or of the director or officer contained in the shareholder agreements; and

| • |  | against any acquisition proposal (as defined in “ — No Solicitation” on page 114 or any other action, agreement or transaction that is intended, or to the knowledge of each of the directors and executive officers would reasonably be expected, to materially impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the merger or the performance of each of the director’s and executive officer’s obligations under the shareholder agreement.

Provided, however, that if there is any amendment, waiver or modification to the merger agreement that is that is effected after the date hereof that (x) reduces or has the effect of reducing the exchange ratio, (y) changes the form of all or any portion of the merger consideration and/or (z) imposes any material condition to the receipt of merger consideration, the obligations of the directors and executive officers described above will be inapplicable.

100

##### Table of Contents

The directors and executive officers also agreed, while the shareholder agreements are in effect, not to, (i) sell, transfer, pledge, encumber, distribute by gift or donation, or otherwise dispose of any of the share of Luther Burbank common stock (or any securities convertible into or exercisable or exchangeable for shares of Luther Burbank common stock) or any interest therein, whether by actual disposition, physical settlement or effective economic disposition through hedging transactions, derivative instruments or other means, (ii) enter into any agreement, arrangement or understanding with any person, or take any other action, that violates or conflicts with or could reasonably be expected to violate or conflict with the director’s and executive officer’s representations, warranties, covenants and obligations under the shareholder agreement, or (iii) take any other action that could reasonably be expected to impair or otherwise adversely affect, in any material respect, the director’s and executive officer’s power, authority and ability to comply with and perform his, her or its covenants and obligations under the shareholder agreement; provided, however, that once the shares of Luther Burbank common stock have been voted at the Luther Burbank special meeting, and provided that at least a majority of all of the issued and outstanding shares of Luther Burbank common have been irrevocably voted in favor of the merger, the merger agreement and the transactions contemplated thereby at the Luther Burbank special meeting as provided for in the shareholder agreement, then the restrictions on the director’s and executive officer’s ability to transfer their shares of Luther Burbank common stock will no longer apply to the directors and executive officers.

In addition, the shareholder agreement entered into by Victor S. Trione, the Chairman of the Luther Burbank board and LB Savings board, provides that Mr. Trione will not sell, transfer, pledge, hypothecate or otherwise dispose of more than one-third of his shares of Luther Burbank common stock during each 12-month period following the effective time of the merger until the expiration of 36 months from the effective time of the merger.

The shareholder agreements will terminate upon the earliest to occur of (i) the date, if any, of termination of the merger agreement in accordance with its terms, (ii) the effective time of the merger, (iii) the date, if any, of any material change to the merger agreement, and (iv) the date the shares of Luther Burbank common stock have been irrevocably voted in favor of the merger, the merger agreement and the transactions contemplated thereby at any meeting of the shareholders of Luther Burbank; provided that the restrictions on the sale, pledge, hypothecation or disposition of Mr. Trione’s holdings of Luther Burbank common stock will not terminate until the expiration of 36 months from the effective time of the merger.

THE MERGER AGREEMENT

The following is a summary of the material provisions of the merger agreement. This summary is qualified in its entirety by reference to the merger agreement, a copy of which is attached as Appendix A to this joint proxy statement/prospectus and is incorporated herein by reference. You should read the merger agreement in its entirety, as it is the legal document governing the merger.

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 Washington Federal and Luther Burbank contained in this joint proxy statement/prospectus or in the public reports of Washington Federal or Luther Burbank filed with the SEC may supplement, update or modify the factual disclosures about Washington Federal and Luther Burbank contained in the merger agreement. The merger agreement contains representations and warranties by Washington Federal, on the one hand, and representations and warranties by Luther Burbank, on the other hand, made solely for the benefit of the other. The representations, warranties and covenants made in the merger agreement by Washington Federal and Luther Burbank were qualified and subject to important limitations agreed to by Washington Federal and Luther Burbank 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 and the bank 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 Washington Federal and Luther Burbank 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 Washington Federal and Luther Burbank at the time they were made or otherwise and should be read only in conjunction with the other information provided elsewhere in this joint proxy statement/prospectus or incorporated by reference into this joint proxy statement/prospectus. Please see the section entitled “Where You Can Find More Information” beginning on page 151.

Structure of the Merger

Each of Washington Federal’s and Luther Burbank’s respective boards has unanimously approved the merger agreement. In the merger, Luther Burbank will be acquired by Washington Federal, in a transaction in which Luther Burbank will merge with and into Washington Federal, with Washington Federal as the surviving institution. Promptly following the completion of the merger, LB Savings will be merged with and into WaFd Bank, with WaFd Bank as the surviving bank. Following consummation of the bank merger, WaFd Bank intends to continue to operate all of the branches acquired from LB Savings.

Prior to the consummation of the merger, Washington Federal and Luther Burbank may, by mutual agreement, modify the structure of the acquisition of Luther Burbank; provided, that no such modification may (i) change the in kind or reduce the amount of the merger consideration, (ii) adversely affect the tax treatment of Luther Burbank’s shareholders pursuant to the merger agreement or (iii) jeopardize receipt of any required regulatory approvals or delay the consummation of the merger and the bank merger.

Consideration to be Received in the Merger

General

At the effective time of the merger, each share of Luther Burbank common stock issued and outstanding immediately prior to the effective time of the merger (including any shares that were issued as restricted stock and for which the vesting conditions have been satisfied) will be converted into, and canceled in exchange for, the right to receive 0.3353 shares of Washington Federal common stock. Cash will be paid in lieu of any fractional share of Washington Federal common stock.

Aggregate Merger Consideration

Upon completion of the merger, Luther Burbank shareholders are expected to receive an aggregate of approximately 17,135,074 shares of Washington Federal common stock, which, based on a $38.15 closing price of Washington Federal common stock on November 11, 2022, the last trading day before Washington Federal announced the merger, represents approximately $653,703,072 of aggregate merger consideration payable to the Luther Burbank shareholders. The aggregate number of shares of Washington Federal common stock referenced in the immediately prior sentence is based on, as of the date of this joint proxy statement/prospectus:

| • |  | 50,790,026 shares of Luther Burbank common stock outstanding;

| • |  | 232,459 shares of Luther Burbank restricted stock outstanding (which assumes that all outstanding awards of Luther Burbank restricted stock are converted into shares of Washington Federal common stock in connection with the merger); and

| • |  | 81,225 Luther Burbank restricted stock units outstanding (which assumes that all outstanding awards of Luther Burbank restricted stock units are converted into shares of Washington Federal common stock in connection with the merger).

Following the completion of the merger, based on the amounts described above and on 65,415,338 shares of Washington Federal common stock outstanding as of January 31, 2023, the former Luther Burbank shareholders will own approximately 21% of the outstanding shares of Washington Federal common stock and the current shareholders of Washington Federal will own the remaining approximately 79% of the outstanding shares of Washington Federal common stock. Shares of Luther Burbank common stock will not be entitled to dissenters’ rights. See the section entitled “No Appraisal or Dissenters’ Rights in the Merger” on page 100.

The amounts and percentages in the immediately prior sentence do not reflect adjustments based upon, take into account or otherwise give effect to:

| • |  | Luther Burbank restricted stock and Luther Burbank restricted stock units awarded to Luther Burbank employees who will become Washington Federal employees; and

| • |  | any tax withholding obligations.

Fractional Shares

No fractional shares of Washington Federal common stock will be issued in the merger. Instead, a former holder of Luther Burbank common stock who would otherwise be entitled to a fractional share interest will receive an amount in cash, without interest, determined by multiplying such fractional interest by the Washington Federal average share price, rounded to the nearest whole cent. No such holder will be entitled to dividends, voting rights or any other rights in respect of any fractional share of Washington Federal common stock.

Treatment of Luther Burbank Restricted Stock and Luther Burbank Restricted Stock Units

Each outstanding award of Luther Burbank restricted stock and Luther Burbank restricted stock units issued pursuant to the Luther Burbank Omnibus Plan (other than the Luther Burbank restricted stock and Luther

103

##### Table of Contents

Burbank restricted stock units held by a continuing employee) will automatically vest in full, effective as of the effective time of the merger. The shares of Luther Burbank restricted stock and Luther Burbank restricted stock units will be converted into, and will be cancelled in exchange for, the right to receive (i) a number of shares of Washington Federal common stock equal to the number of such shares of Luther Burbank restricted stock and Luther Burbank restricted stock units multiplied by the exchange ratio, provided that any fractional shares of Washington Federal common stock will receive cash in lieu of fractional shares of Washington Federal common stock, plus (ii) the amount in cash equal to the sum of any accrued dividends or dividend equivalents that are payable in cash, pursuant to the terms of the Luther Burbank restricted stock or Luther Burbank restricted stock units.

Each share of Luther Burbank restricted stock and each Luther Burbank restricted stock unit held by a continuing employee, to the extent expressly assumed by Washington Federal, will automatically cease to represent a share of Luther Burbank restricted stock or Luther Burbank restricted stock units and will be substituted with a share of Washington Federal restricted stock or a Washington Federal restricted stock unit. The number of shares of Washington Federal common stock subject to each such share of Luther Burbank restricted stock or each Luther Burbank restricted stock unit will be equal to the product (rounded to the nearest whole number) of the number of shares of Luther Burbank common stock subject to Luther Burbank restricted stock or Luther Burbank restricted stock units immediately prior to the effective time of the merger multiplied by the exchange ratio.

Each share of Luther Burbank restricted stock and each Luther Burbank restricted stock unit held by a continuing employee, to the extent not expressly assumed by Washington Federal, will automatically vest in full, effective as of the effective time of the merger, and such shares of Luther Burbank restricted stock and such Luther Burbank restricted stock units will be converted into, and will be cancelled in exchange for, the right to receive (i) a number of shares of Washington Federal common stock equal to the number of shares of Luther Burbank restricted stock or Luther Burbank restricted stock units multiplied by the exchange ratio, provided that any fractional shares of Washington Federal common stock will receive cash in lieu of fractional shares of Washington Federal common stock, plus (ii) the amount in cash equal to the sum of any accrued dividends or dividend equivalents that are payable in cash, pursuant to the terms of the Luther Burbank restricted stock or Luther Burbank restricted stock units.

Effective Time and Completion of the Merger

The merger will become effective upon the acceptance of the articles of merger to be filed with the Secretary of State of the State of Washington in accordance with the provisions of applicable Washington law (the “effective date”). Subject to the satisfaction or waiver of the conditions set forth in the merger agreement, the parties will file the articles of merger with the Secretary of State of the State of Washington on (i) a date mutually selected by Washington Federal and Luther Burbank after such satisfaction or waiver which is no later than the later of (a) five business days after such satisfaction or waiver or (b) the first month end following such satisfaction or waiver, unless such date provided for in clause (b) occurs other than in the last month of a fiscal quarter and is more than 14 calendar days after the date provided for in clause (a), in which case the date will be the date provided for in clause (a), or (ii) such other date to which the parties may mutually agree in writing. The parties will cause a copy of the articles of merger certified by the Secretary of State of the State of Washington to be filed with the Secretary of State of the State of California immediately following the receipt of such certified copy from the Secretary of State of the State of Washington. The closing will take place by electronic exchange of documents at 10:00 a.m. Pacific Time on the effective date, or at such other date or time mutually agreed upon by Washington Federal and Luther Burbank in writing.

Procedures for Exchanging Shares of Luther Burbank Common Stock

Exchange Procedures

Prior to the effective date of the merger, Washington Federal will appoint its transfer agent, Broadridge Corporate Issuer Solutions, Inc., as the exchange agent under the merger agreement. Promptly following the

104

##### Table of Contents

effective date of the merger (but in no event more than three business days after the effective date of the merger), the exchange agent will mail and otherwise make available to each holder of record of Luther Burbank common stock a notice and a form of letter of transmittal advising such holder of the effectiveness of the merger and the and instructions for the surrender of the holder’s Luther Burbank stock certificate(s) and/or conversion of book-entry shares for the merger consideration, as well as any dividends or distributions paid, pursuant to the terms of the merger agreement. Upon surrender of a stock certificate or book-entry shares of Luther Burbank common stock for exchange and cancellation to the exchange agent, together with a duly executed transmittal letter, the holder of such certificate or book-entry shares will be entitled to receive the merger consideration allocated to him or her and the certificate or book-entry shares for Luther Burbank common stock will be canceled. No interest will be paid or accrued on any cash paid in lieu of fractional shares of Luther Burbank common stock.

Luther Burbank shareholders who surrender their stock certificates or book-entry shares and complete the transmittal materials, or who have taken other steps to surrender the evidence of their stock interest in Luther Burbank in accordance with the instructions accompanying the transmittal letter, will, upon the exchange agent’s acceptance of such stock certificates or book-entry shares and transmittal materials or stock interest, be entitled to evidence of issuance in book entry form the number of whole shares of Washington Federal common stock in to which the aggregate number of shares of Luther Burbank surrendered have been converted pursuant to the merger agreement.

If a Luther Burbank shareholder has lost his or her Luther Burbank stock certificate, or the Luther Burbank stock certificate has been lost, stolen or destroyed, the Luther Burbank shareholder may be required to deliver an affidavit of loss and indemnity agreement and/or and a lost certificate bond as a condition to receiving any merger consideration to which he or she may be entitled.

After completion of the merger, no transfers of Luther Burbank common stock issued and outstanding immediately prior to the completion of the merger will be allowed. Luther Burbank stock certificates that are presented for transfer after the completion of the merger will be canceled and exchanged for the appropriate merger consideration.

Withholding

Washington Federal will be entitled to deduct and withhold, or cause the exchange agent to deduct and withhold, from any cash in lieu of fractional shares or on account of accrued dividends or dividend equivalents or any other consideration payable under the merger agreement to any holder of Luther Burbank common stock or Luther Burbank restricted stock the amounts it is required to deduct and withhold under the Code or any state, local, or foreign tax law or regulation. 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.

Dividends and Distributions

No dividends or other distributions declared with respect to Washington Federal common stock after completion of the merger will be paid to the holder of any unsurrendered Luther Burbank stock certificates or untransferred shares of Luther Burbank common stock held in book-entry form with respect to the Washington Federal common stock represented by those certificates or book-entry shares until those certificates or book-entry shares have been properly surrendered. After the proper surrender of any such previously unsurrendered Luther Burbank stock certificate, or proper transfer of any such previously untransferred shares of Luther Burbank common stock held in book-entry form, the holder of the certificate or such book-entry shares 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 Washington Federal common stock, which the shares of Luther Burbank common stock represented by such old certificate have been converted into the right to receive under the merger agreement.

Representations and Warranties

Pursuant to the merger agreement, Washington Federal and Luther Burbank made certain customary representations and warranties relating to their respective companies, subsidiaries, businesses and matters related to the merger. For detailed information concerning these representations and warranties, reference is made to Article V of the merger agreement included as Appendix A to this joint proxy statement/prospectus. Such representations and warranties generally must remain accurate through the completion of the merger, unless the fact or facts that caused a breach of a representation and warranty has not had or is not reasonably likely to have a material adverse effect on the party making the representation and warranty. See the section entitled “— Conditions to Completion of the Merger” beginning on page 115.

The merger agreement contains representations and warranties that Washington Federal and Luther Burbank made to and solely for the benefit of each other. These representations and warranties are subject to materiality standards which may differ from what may be viewed as material by investors and shareholders, and, in certain cases, were used for the purpose of allocating risk among the parties rather than establishing matters as facts. The assertions embodied in those representations and warranties also are qualified by information in confidential disclosure schedules that the parties have exchanged in connection with signing the merger agreement. Although neither Washington Federal nor Luther Burbank believes that the disclosure schedules contain information that the federal securities laws require to be publicly disclosed, the disclosure schedules do contain information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the merger agreement.

Accordingly, neither shareholders of either Washington Federal or Luther Burbank should rely on the representations and warranties as characterizations of the actual state of facts, since they were only made as of the date of the merger agreement and are modified in important part by the underlying disclosure schedules. Moreover, information concerning the subject matter of the representations and warranties may have changed since the date of the merger agreement, which subsequent information may or may not be fully reflected in Washington Federal’s or Luther Burbank’s public disclosures.

Covenants and Agreements

Conduct of Business Pending the Merger

The merger agreement contains certain covenants of the parties regarding the conduct of their respective businesses pending consummation of the merger. Those covenants, which are contained in Article IV or the merger agreement included as Appendix A to this joint proxy statement/prospectus, are briefly described below.

Pending consummation of the merger, except as expressly contemplated or permitted by the merger agreement, as disclosed to Washington Federal or as required by applicable law, regulation or policies imposed by any governmental authority, Luther Burbank may not, and will cause each of its subsidiaries not to, among other things, take the following actions without Washington Federal’s prior written consent:

| • |  | conduct its business other than in the ordinary and usual course consistent with past practice or fail to use commercially reasonable best efforts to preserve its business organization, keep available the present services of its employees (except in the case of terminations of employees for cause) and preserve for itself and Washington Federal the goodwill of the customers of Luther Burbank, its subsidiaries and others with whom business relations exist;

Regulatory Matters

Washington Federal and Luther Burbank have agreed to cooperate with each other and use their reasonable best efforts to prepare and file all necessary documentation (and in the case of any initial application filings with governmental authorities, Washington Federal has agreed to use its best efforts to make any such filing within 30 calendar days of the date of the merger agreement or as promptly as reasonably practicable thereafter), and to file all required notices and obtain all permits, consents, approvals and authorizations of all governmental authorities necessary to consummate the merger and the bank merger. Washington Federal and Luther Burbank have also agreed that they will consult each other with respect to the obtaining of all permits, consents, approvals waivers and authorizations of all governmental authorities necessary or advisable to consummate the merger and the bank merger, to keep each other apprised of the status of non-confidential material matters related relating to completion of the merger and bank merger and to provide each other a copy of all correspondence to or from any governmental authority in connection with the merger and bank merger and a written description of any material or significant oral communications with any governmental authority in connection with the merger and bank merger.

Washington Federal and Luther Burbank have also agreed to, upon request, to furnish the other party with all information concerning themselves, their subsidiaries, directors and officers and stockholders and such other matters as may be reasonably necessary or advisable in connection with any filing, notice or application made by or on behalf of Washington Federal, Luther Burbank or any of their respective subsidiaries to any governmental authority.

Notwithstanding the foregoing, Washington Federal and Luther Burbank are not required to take any action, or commit to take any action that would reasonably be likely to have a material adverse effect on Washington Federal after giving effect to the merger (measured on a scale relative to Luther Burbank and its subsidiaries, taken as a whole).

In order to complete the transactions contemplated by the merger agreement, Washington Federal and Luther Burbank must first file all required notices and obtain all regulatory approvals, consents and orders required in connection with both the merger and the bank merger. In this regard, the parties must obtain the approval of the FDIC and the approval of the WDFI for the bank merger, and provide notice of the bank merger to the CDFPI. Washington Federal was also advised by the CDFPI to file a request for an order of exemption pursuant to Section 1260 of the California Financial Code to avoid having to file a change of control application under Section 1251 of the California Financial Code for the momentary acquisition of control of LB Savings before it is merged with WaFd Bank. In connection with communications with the FRBSF, Washington Federal was advised that prior approval of the Federal Reserve Board is not required for the merger and the momentary acquisition of control of LB Savings because it qualifies as a transaction not requiring Federal Reserve Board approval pursuant to 12

111

##### Table of Contents

CFR 225.12(d)(2). Thus, a bank holding company application is not required for the transaction. Rather, Washington Federal must provide written notice of the proposed transaction to the FRBSF pursuant to the requirements of 12 CFR 225.12(d)(2). Applications to merge the banks were filed with the FDIC on or about January 6, 2023 and the WDFI on or about January 9, 2023, and the notice to the CDFPI was filed on or about January 9, 2023. Pursuant to the FDIC’s application processing guidelines set forth in 12 CFR Part 303, the agency requested additional information on the bank merger application on February 6, 2023. Pursuant to an extension granted by the FDIC, Washington Federal and Luther Burbank are working cooperatively to provide the requested information on or about April 7, 2023. Finally, Washington Federal submitted the required notice to the FRBSF and the request for an exemption to the CDFPI on March 1, 2023. Pursuant to the exemption request, the CDFPI issued an order of exemption approving the exemption request on March 21, 2023.

Employee and Benefit Plan Matters

As soon as administratively practicable after the effective time of the merger, Washington Federal will take all reasonable action so continuing employees will be entitled to participate in each Washington Federal employee benefit plan of general applicability to the same extent as similarly-situated employees of Washington Federal and its subsidiaries, provided that coverage will be continued under the corresponding benefit plans of Luther Burbank and its subsidiaries until such continuing employees are permitted to participate in the Washington Federal benefit plans. Washington Federal and WaFd Bank, however, will not be required to make any grants to any former employee of Luther Burbank and its subsidiaries under any discretionary equity compensation plan of Washington Federal. For purposes of determining eligibility to participate in, the vesting of benefits and for all other purposes, other than for accrual of pension benefits under, the Washington Federal employee benefit plans, Washington Federal will recognize years of service with Luther Burbank and its subsidiaries, to the same extent as such service was credited for such purpose by Luther Burbank and its subsidiaries, except where such recognition would result in duplication of benefits or to the extent not otherwise permissible under the terms of a Washington Federal benefit plan. Nothing contained in the merger agreement will limit the ability of Washington Federal to amend or terminate any Washington Federal or Luther Burbank benefit plan in accordance with their terms at any time.

At and following the effective time of the merger, Washington Federal will honor and will continue to be obligated to perform, in accordance with their terms, all benefit obligations to, and contractual rights of, current and former employees of Luther Burbank and its subsidiaries and current and former directors of Luther Burbank and its subsidiaries existing as of the effective date of the merger, as well as all bonus, deferred compensation, supplemental retirement plan, salary continuation, severance, termination, change in control and other existing plans and policies of Luther Burbank and its subsidiaries that were previously disclosed to Washington Federal.

At the time the continuing employees of Luther Burbank and its subsidiaries become eligible to participate in a medical, dental, health, life or disability plan of Washington Federal or its subsidiaries, Washington Federal will cause each such plan to:

| • |  | waive any preexisting condition limitations to the extent such conditions are covered under the applicable medical, health or dental plans of Washington Federal;

| • |  | provide full credit under such medical, health and dental plans for any deductibles, co-payment and out-of-pocket expenses incurred by the continuing employees and their beneficiaries during the portion of the calendar year prior to such participation;

| • |  | waive any waiting period limitation or evidence of insurability requirement which would otherwise be applicable to such continuing employee on or after the effective time of the merger to the extent such continuing employee had satisfied any similar limitation or requirement under a corresponding Luther Burbank plan prior to the effective time of the merger, provided, however, that such waiver will not be required to the extent that such waiver would result in a duplication of benefits or to the extent not otherwise permissible under the terms of a contract insuring benefits under the Washington Federal benefit plans; and

112

##### Table of Contents

| • |  | for a period of at least two years, be sponsored by one or more entities agreed to by Washington Federal and Luther Burbank.

Luther Burbank and Washington Federal have cooperated in good faith to determine a mutually agreeable communications plan regarding employment decisions and continuing employees, and Washington Federal will, by a date mutually agreed to by Washington Federal and Luther Burbank, identify and deliver offer letters to all continuing employees. Pursuant to a severance plan previously adopted by Luther Burbank, those employees of Luther Burbank and its subsidiaries who are not offered employment by Washington Federal or WaFd Bank following the merger, who are not a party to an employment agreement or otherwise entitled to an existing severance package, and who sign and deliver a termination and release agreement within 30 days of the closing of the merger will be entitled to receive a single lump sum payment of severance based on a general formula of two weeks of salary for each year of completed service with Luther Burbank, up to a maximum of six months and a minimum based on the seniority of the employee.

Pursuant to the merger agreement, Luther Burbank is required, prior to the closing of the merger, to have made all discretionary employee contributions to the Luther Burbank 401(k) Plan, to provide for full vesting of all non-elective contributions under such Luther Burbank 401(k) Plan for all participants, and to take all actions necessary to terminate such Luther Burbank 401(k) Plan effective no later than the business day preceding the closing date of the merger.

Assumption of Luther Burbank Debt Obligations

Washington Federal has agreed to assume, or to cause one of its subsidiaries to assume, Luther Burbank’s obligations under the Luther Burbank debt obligations. As of December 31, 2022, an aggregate principal amount of $95,000,000 of the senior notes was outstanding and an aggregate principal amount of $61,857,000 of the subordinated debentures were outstanding.

Recommendation of the Luther Burbank Board and the Washington Federal Board

Pursuant to the merger agreement, the Luther Burbank board is required, at all times prior to and during the Luther Burbank special meeting, to recommend that Luther Burbank shareholders approve the merger agreement and the merger. The Luther Burbank board may not withdraw, modify or qualify in any manner adverse to Washington Federal or the consummation of the merger such recommendation or take any other action or make any other public statement in connection with the Luther Burbank special meeting inconsistent with such recommendation, or resolve or agree to take any such actions, except as described below. Notwithstanding any change in recommendation by the Luther Burbank board, the merger agreement will be submitted to the Luther Burbank shareholders at the Luther Burbank special meeting for the purpose of approving the merger agreement and any other matters required to be approved by Luther Burbank’s shareholder for consummation of the merger. In addition, Luther Burbank may not submit to the vote of its shareholders any acquisition proposal other than the merger.

The Luther Burbank board is permitted to change its recommendation if and only to the extent that Luther Burbank has complied in all material respects with the merger agreement and the Luther Burbank board, after consulting with its outside counsel and financial advisor, has determined in good faith that failure to do so would more likely than not result in a breach of the Luther Burbank board’s fiduciary duties under applicable law. If the Luther Burbank board intends to change its recommendation following an acquisition proposal, as described in the section entitled “— No Solicitation” below, it must have first concluded in good faith, after giving effect to all of the adjustments to the terms and conditions of the merger agreement that may be offered by Washington Federal, that another acquisition proposal constitutes a superior proposal, as defined in the section entitled “— No Solicitation” below. Luther Burbank also must notify Washington Federal at least five business days in advance of its intention to change its recommendation in response to the superior proposal, including the identity of the party making the acquisition proposal, and furnish to Washington Federal all of the material terms and conditions of such superior proposal. Prior to effecting a change to the Luther Burbank board’s recommendation, Luther Burbank must, and must cause its financial and legal advisors to, during the period following its delivery of the required notice, negotiate in good faith with Washington Federal for a period of up to five business days to

113

##### Table of Contents

the extent Washington Federal desires to negotiate to make such adjustments in the terms and conditions of the merger agreement so that the other acquisition proposal ceases to constitute a superior proposal.

Pursuant to the merger agreement, the Washington Federal board is required to recommend that Washington Federal shareholders approve the issuance of Washington Federal common stock in the merger and any other matters required to be approved by Washington Federal’s shareholders for the consummation of the merger at all times prior to and during the Washington Federal special meeting.

No Solicitation

The merger agreement provides that Luther Burbank will, and will direct and use its reasonable best efforts to cause its affiliates, directors, officers, employees, agents and representatives (including, without limitation, any investment banker, financial advisor, attorney, accountant or other representative retained by it), (collectively, the “representatives”) to, immediately cease any discussions or negotiations with any other parties that may have been ongoing with respect to the possibility or consideration of any acquisition proposal, and will use its reasonable best efforts to enforce any confidentiality or similar agreement relating to any acquisition proposal. For purposes of the merger agreement, “acquisition proposal” is defined to mean any inquiry, proposal or offer, filing of any regulatory application or notice or disclosure of an intention to do any of the foregoing from any person relating to any (i) direct or indirect acquisition or purchase of a business that constitutes 25% or more of the total revenues, net income, assets, or deposits of Luther Burbank and its subsidiaries taken as a whole; (ii) direct or indirect acquisition or purchase of any class of equity securities representing 25% or more of the voting power of Luther Burbank or LB Savings; (iii) tender offer or exchange offer that if consummated would result in any person beneficially owning 25% or more of any class of equity securities of Luther Burbank or LB Savings; or (iv) merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving Luther Burbank or LB Savings, other than the transactions contemplated by the merger agreement.

From the date of the merger agreement through the effective time of the merger, neither Luther Burbank nor any of its subsidiaries will, nor cause their respective directors, officers or employees or any other representative retained by it not to, directly or indirectly through another person, (i) solicit, initiate, or encourage, including by way of furnishing information or assistance, or take any other action designed to facilitate or that is likely to result in, any inquiries or the making of any proposal or offer that constitutes, or is reasonably likely to lead to, any acquisition proposal, (ii) provide any confidential information or data to any person relating to any acquisition proposal, (iii) participate in any discussions or negotiations regarding any acquisition proposal, (iv) waive, terminate, modify, or fail to enforce any provision of any contractual “standstill” or similar obligations of any person other than Washington Federal or its affiliates, (v) approve or recommend, propose to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, asset purchase agreement or share exchange agreement, option agreement or similar agreement related to any acquisition proposal or propose to take any of these actions, or (vi) make or authorize any statement, recommendation, or solicitation in support of any acquisition proposal.

However, prior to the date of the Luther Burbank special meeting, if the Luther Burbank board determines in good faith, after consulting with its outside legal and financial advisors, that the failure to do so would more likely than not result in a breach of its fiduciary duties under applicable law, Luther Burbank may, in response to a bona fide, written acquisition proposal not solicited in violation of the merger agreement that the Luther Burbank board determines in good faith constitutes a superior proposal, subject to providing two business days prior written notice of its decision to take such action to Washington Federal and identifying the person making the proposal and all the material terms and conditions of the proposal and compliance with the merger agreement:

| (i) | furnish information with respect to itself to any person making a superior proposal pursuant to a customary confidentiality agreement (as determined by Luther Burbank after consultation with its

114

##### Table of Contents

| outside counsel) on terms no more favorable to the person than the terms contained in the confidentiality agreement between Luther Burbank and Washington Federal are to Washington Federal; and

| (ii) | participate in discussions or negotiations regarding the superior proposal.

For purposes of the merger agreement, “superior proposal” is defined to mean any bona fide written proposal made by a third party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction, for consideration consisting of cash and/or securities, more than 50% of the combined voting power of the shares of Luther Burbank common stock then outstanding or all or substantially all of Luther Burbank’s consolidated assets, which the Luther Burbank board determines in good faith, after taking into account all legal, financial, regulatory, and other aspects of the proposal and the person making the proposal, including any break-up fees, expense reimbursement provisions, and conditions to consummation, and after taking into account the advice of Luther Burbank’s financial advisor, which will be a recognized investment banking firm, and outside counsel, (i) is more favorable from a financial point of view to its shareholders than the merger, (ii) is reasonably likely to be consummated on the terms set forth, and (iii) for which financing, to the extent required, is then committed or which, in the good faith judgment of the Luther Burbank board, is reasonably likely to be obtained by the third party.

In addition to these obligations, Luther Burbank will promptly, within 24 hours, advise Washington Federal orally and in writing of its receipt of any acquisition proposal, and keep Washington Federal reasonably informed, on a current basis, of the continuing status of the inquiry, including the material terms and conditions of the inquiry and any material changes to the inquiry, and will contemporaneously provide to Washington Federal all materials provided to or made available to any third party that were not previously provided to Washington Federal.

Termination of the Merger Agreement

The merger agreement may be terminated, and the merger may be abandoned, at any time prior to the effective time of the merger (whether before or after receipt of the requisite Luther Burbank shareholder approval or the requisite Washington Federal shareholder approval):

| • |  | by the mutual written consent of Washington Federal and Luther Burbank;

| • |  | if the terminating party is not in material breach of any representation, warranty, covenant, or agreement contained in the merger agreement, by Washington Federal or Luther Burbank, in the event of a breach by the other party of any representation, warranty, covenant, or agreement contained in the merger agreement that (i) cannot be or has not been cured within 30 days of the giving of written notice to the breaching party of such breach, and (ii) would entitle the non-breaching party not to consummate the merger under the merger agreement;

| • |  | by Washington Federal or Luther Burbank, in the event that the merger is not consummated by the outside date, except to the extent that the failure to consummate the merger by the outside date is due to (i) the failure of the party seeking to terminate to perform or observe its covenants and agreements set forth in the merger agreement, or (ii) the failure of any of the applicable Luther Burbank shareholders (if Luther Burbank is the party seeking to terminate) to perform or observe their respective covenants under their respective shareholder agreement with Luther Burbank and Washington Federal, except that the outside date may be extended to February 29, 2024 by either Washington Federal or Luther Burbank by written notice to the other party if the closing has not occurred by the outside date, and on such date all of the conditions to the obligations to the parties to complete the merger have been satisfied or waived (other than those conditions that are to be satisfied at the closing, provided such conditions would have been capable of being satisfied as on the outside date) other than the regulatory approval condition, as further described in the section entitled “— Conditions to Completion of the Merger” on page 115;

Effect of Termination

If the merger agreement is terminated, it will become void and have no effect, except that (i) certain 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 and (ii) neither Washington Federal nor Luther Burbank will be relieved ore released from any liabilities or damages arising out of fraud or willful breach of any provision of the merger agreement.

Termination Fee

The merger agreement provides that Luther Burbank must pay Washington Federal the termination fee of a $26.17 million under the circumstances and in the manner described below:

119

##### Table of Contents

| the date of such consummation of such control transaction. A “control transaction” is defined for purposes of this joint proxy statement/prospectus as (i) the acquisition by any person, whether by purchase, merger, consolidation, sale, transfer or otherwise, in one transaction or any series of transactions, of a majority of the voting power of the outstanding securities of Luther Burbank or LB Savings or a majority of the assets of Luther Burbank or LB Savings, (ii) any issuance of securities resulting in the ownership by any person of more than 50% of the voting power of Luther Burbank or by any person other than Luther Burbank or its subsidiaries of more than 50% of the voting power of LB Savings or (iii) any merger, consolidation or other business combination transaction involving Luther Burbank or any of its subsidiaries as a result of which the shareholders of Luther Burbank cease to own, in the aggregate, at least 50% of the total voting power of the entity surviving or resulting from such transaction.

Any termination fee that becomes payable pursuant to the merger agreement will be paid by wire transfer of immediately available funds to an account designated by Washington Federal.

If Luther Burbank fails to timely pay the termination fee to Washington Federal, Luther Burbank will be obligated to pay the costs and expenses (including reasonable legal fees and expenses) incurred by Washington Federal to collect such payment, provided Washington Federal prevails on the merits, together with interest.

Expenses

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE MERGER

This discussion addresses the material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) of Luther Burbank common stock. The discussion is based on provisions of the Code, U.S. Treasury regulations, administrative rulings of the Internal Revenue Service (the “IRS”) and judicial decisions, all as currently in effect and all of which are subject to change (possibly with retroactive effect) and to differing interpretations.

For purposes of this discussion, we use the term “U.S. holder” to mean:

| • |  | an individual who is a citizen or resident of the United States;

| • |  | a corporation (or other entity taxable as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia;

| • |  | a trust that (i) is subject to the supervision of a court within the United States and the control of one or more U.S. persons or (ii) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person; or

| • |  | an estate that is subject to U.S. federal income taxation on its income regardless of its source.

This discussion applies only to U.S. holders that hold their Luther Burbank common stock as a capital asset within the meaning of Section 1221 of the Code (generally, property held for investment), and does not address all aspects of U.S. federal income taxation that may be relevant to a particular U.S. holder in light of the holder’s particular circumstances or to U.S. holders subject to special treatment under the U.S. federal income tax laws, including:

| • |  | financial institutions

| • |  | pass-through entities and investors therein;

| • |  | persons liable for the alternative minimum tax;

| • |  | insurance companies;

| • |  | tax-exempt organizations;

| • |  | dealers or brokers in securities, commodities or currencies;

| • |  | traders in securities that elect to use a mark-to-market method of accounting;

| • |  | persons that hold Luther Burbank common stock as part of a straddle, hedge, constructive sale or conversion transaction or other risk reduction transaction;

| • |  | regulated investment companies;

| • |  | real estate investment trusts;

| • |  | retirement plans, individual retirement accounts or other tax-deferred accounts;

| • |  | persons whose “functional currency” is not the U.S. dollar;

| • |  | U.S. expatriates and former long-term residents of the United States; and

| • |  | persons who acquired their Luther Burbank common stock through the exercise of an employee stock option, as a restricted stock or restricted stock unit award, or otherwise as compensation.

Furthermore, this discussion does not address any state, local, or non-U.S. tax consequences, or U.S. federal estate, gift, unearned income Medicare contribution tax, alternative minimum tax or other non-income tax consequences.

121

##### Table of Contents

If a partnership or other pass-through entity for U.S. federal income tax purposes holds Luther Burbank common stock, the tax treatment of a partner of such partnership or owner of such other pass-through entity will generally depend upon the status of the partner or owner and the activities of the partnership or other pass-through entity. Partnerships and other pass-through entities holding Luther Burbank common stock, and any persons who are partners or owners of such an entity, should consult their own tax advisors regarding the tax consequences of the merger.

The actual U.S. federal income tax consequences of the merger to you may be complex and will depend on your specific situation and on factors that are not within our control. This discussion does not constitute tax advice. You should consult with your own tax advisor as to the tax consequences of the merger in your particular circumstances, including the applicability and effect of the alternative minimum tax, the unearned income Medicare contribution tax, the estate and gift tax, and any state, local or non-U.S. and other tax laws and of changes in those laws.

U.S. Federal Income Tax Consequences of the Merger Generally

The merger is intended to qualify as a “reorganization” under Section 368(a) of the Code for U.S. federal income tax purposes. It is a condition to Luther Burbank’s obligation to complete the merger that Luther Burbank receives a written opinion of its counsel, H&K, dated as of 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 Washington Federal’s obligation to complete the merger that Washington Federal receives an opinion of its counsel, DWT, dated as of 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 the assumption that the merger will be completed in the manner set forth in the merger agreement and the registration statement on Form S-4 of which this joint proxy statement/prospectus forms a part, and on representation letters provided by Luther Burbank and Washington Federal to be delivered at the time of the closing. Those opinions will also be based on the assumption that the representations set forth in the merger agreement and the representation letters are, as of the effective time of the merger, true and complete without qualification and that the representation letters are executed by appropriate and authorized officers of Luther Burbank and Washington Federal. If any of the assumptions or representations upon which such opinions are based is inconsistent with the actual facts with respect to the merger, the U.S. federal income tax consequences of the merger could be adversely affected and could differ from those described below.

In addition, neither of the tax opinions given in connection with the merger or in connection with the filing of the registration statement will be binding on the IRS or any court. Neither Luther Burbank nor Washington Federal intends to request any ruling from the IRS as to the U.S. federal income tax consequences of the merger, and consequently, there is no assurance that the IRS will treat the merger as a “reorganization” within the meaning of Section 368(a) of the Code.

If the merger does not qualify as a reorganization, the transaction would be treated as a taxable transaction on which gain or loss would be recognized. Accordingly, each holder of Luther Burbank common stock should consult its own tax advisor with respect to the particular tax consequences of the merger to such holder.

Subject to the foregoing, the material U.S. federal income tax consequences of the merger will be as follows:

| • |  | no income, gain or loss will be recognized by U.S. holders of Luther Burbank common stock that receive Washington Federal common stock in exchange for Luther Burbank common stock pursuant to the merger (except for any income, gain or loss that may result from (i) the receipt of cash in lieu of a fractional share of Washington Federal common stock (as discussed below under the section entitled “— Cash Received In Lieu of a Fractional Share of Washington Federal Common Stock”) and (ii) the receipt by holders of Luther Burbank restricted stock or Luther Burbank restricted units of cash on

122

##### Table of Contents

| account of accrued dividends or dividend equivalents (as discussed below under the section entitled “— Cash Received on Account of Accrued Dividends or Dividend Equivalents Payable Pursuant to the Terms of the LBC Restricted Stock or LBC Restricted Stock Unit”));

| • |  | the aggregate tax basis of Washington Federal common stock received by shareholders of Luther Burbank pursuant to the merger will be the same as the tax basis of the shares of Luther Burbank common stock exchanged therefore, (i) decreased by any portion of such tax basis allocated to fractional shares of Washington Federal common stock that are treated as redeemed by Washington Federal (as described in the section entitled “— Cash Received In Lieu of a Fractional Share of Washington Federal Common Stock” below), (ii) decreased by the amount of cash received by a Luther Burbank shareholder in the merger (other than cash received with respect to fractional shares and other than cash received on account of accrued dividends or dividend equivalents as described in the section entitled “— Cash Received on Account of Accrued Dividends or Dividend Equivalents Payable Pursuant to the Terms of the LBC Restricted Stock or LBC Restricted Stock Unit” below), and (iii) increased by the amount of gain recognized by a Luther Burbank shareholder in the merger (other than gain recognized with respect to fractional shares and any gain treated as a dividend as described below); and

| • |  | the holding period of the Washington Federal common stock received in exchange for Luther Burbank common stock will include the holding period of the Luther Burbank common stock surrendered in the exchange.

If a U.S. holder of Luther Burbank common stock acquired different blocks of Luther Burbank common stock at different times or at different prices, such holder’s basis and holding period may be determined with reference to each block of Luther Burbank common stock. Any such holder should consult its tax advisor regarding the manner in which Washington Federal common stock received in the merger should be allocated among different blocks of Luther Burbank common stock and with respect to identifying the bases or holding periods of the particular Washington Federal common stock received in the merger.

Cash Received In Lieu of a Fractional Share of Washington Federal Common Stock

A U.S. holder of Luther Burbank common stock that receives cash in lieu of a fractional share of Washington Federal common stock will be treated as having received the fractional share pursuant to the merger and then as having exchanged the fractional share for cash in a redemption by Washington Federal of such fractional share. As a result, such a U.S. holder generally will recognize gain or loss equal to the difference between the amount of cash received and the holder’s basis in the fractional share, as set forth above. This gain or loss will be long-term capital gain or loss if, as of the effective date of the merger, the holding period for such stock is greater than one year. The deductibility of capital losses is subject to limitations.

Cash Received on Account of Accrued Dividends or Dividend Equivalents Payable Pursuant to the Terms of the LBC Restricted Stock or LBC Restricted Stock Unit

A U.S. holder of Luther Burbank common stock that receives Washington Federal common stock and cash on account of accrued dividends or dividend equivalents pursuant to Luther Burbank restricted stock or Luther Burbank restricted stock units generally will recognize gain (but not loss) in an amount equal to the lesser of (i) the amount of gain realized (i.e., the excess of the sum of the amount of cash, but not cash received in lieu of a fractional share, and the fair market value of the Washington Federal common stock received pursuant to the merger over such shareholder’s adjusted tax basis in its shares of Luther Burbank common stock surrendered), and (ii) the amount of cash (but not cash in lieu of a fractional share) received pursuant to the merger. Any recognized gain will generally be long-term capital gain if the Luther Burbank shareholder’s holding period with respect to the Luther Burbank common stock surrendered is more than one year. If, however, the cash received has the effect of the distribution of a dividend, the gain would be treated as a dividend to the extent of such holder’s ratable share of Luther Burbank’s accumulated earnings and profits as calculated for U.S. federal income tax purposes.

123

##### Table of Contents

Information Reporting and Backup Withholding

A non-corporate U.S. holder may be subject to backup withholding (currently at a rate of 24%) on any cash received in the merger, including cash received in lieu of a fractional share of Washington Federal common stock. Backup withholding generally will not apply, however, to any such U.S. holders who:

| • |  | furnish a correct taxpayer identification number, certify that they are not subject to backup withholding on Form W-9 or successor form and otherwise comply with all the applicable requirements of the backup withholding rules; or

| • |  | provide proof that they are otherwise exempt from backup withholding.

Any amounts withheld under the backup withholding rules will generally be allowed as a refund or credit against the U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

A U.S. holder receiving shares of Washington Federal common stock as a result of the merger will be required to retain records pertaining to the merger. Each U.S. holder that is required to file a U.S. federal income tax return and is a “significant holder” will be required to file a statement with the holder’s U.S. federal income tax return setting forth the holder’s basis (determined immediately before the exchange) in the Luther Burbank common stock surrendered and the fair market value (determined immediately before the exchange) of the Luther Burbank common stock that is exchanged by such holder pursuant to the merger. A “significant holder” is a U.S. holder that receives shares of Washington Federal common stock in the merger and that, immediately before the merger, owned at least 5% of the outstanding stock of Luther Burbank (by vote or value) or securities of Luther Burbank with a tax basis of $1 million or more.

The preceding discussion is intended only as a summary of material U.S. federal income tax consequences of the merger. It is not tax advice or a complete analysis or discussion of all potential tax effects that may be important to you. Therefore, you are strongly encouraged to consult your tax advisor as to the specific tax consequences to you resulting from the merger, including tax return reporting requirements, the applicability and effect of federal, state, local, and other tax laws and the effect of any proposed changes in the tax laws.

NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

Note 1 – Basis of Presentation

Washington Federal’s and Luther Burbank’s historical financial statements were prepared in accordance with U.S. GAAP and presented in U.S. dollars. As discussed in Note 3, certain reclassifications were made to align Washington Federal’s and Luther Burbank’s financial statement presentation. Washington Federal has not identified all adjustments necessary to conform Luther Burbank’s accounting policies to Washington Federal’s accounting policies. Upon completion of the merger, or as more information becomes available, Washington Federal will perform a more detailed review of Luther Burbank’s accounting policies. As a result of that review, differences could be identified between the accounting policies of the two companies that, when conformed, could have a material impact on the combined company’s financial information.

The accompanying unaudited pro forma condensed combined financial statements and related notes were prepared using the acquisition method of accounting under the provisions of ASC 805, with Washington Federal considered the acquirer of Luther Burbank. ASC 805 requires, among other things, that the assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date. For purposes of the unaudited pro forma condensed combined balance sheet, the purchase consideration as of February 24, 2023, has been allocated to the assets acquired and liabilities assumed of Luther Burbank based upon management’s preliminary estimate of their fair values as of December 31, 2022. Washington Federal has not completed the valuation analysis and calculations in sufficient detail necessary to arrive at the required estimates of the fair market value of the Luther Burbank assets to be acquired or liabilities assumed, other than a preliminary estimate for intangible assets and certain financial assets and financial liabilities. Accordingly, apart from the aforementioned, certain Luther Burbank assets and liabilities are presented at their respective carrying amounts and should be treated as preliminary values. Any differences between the fair value of the consideration transferred and the fair value of the assets acquired and liabilities assumed will be recorded as goodwill. Accordingly, the purchase price allocation and related adjustments reflected in these unaudited pro forma condensed combined financial statements are preliminary and subject to revision based on a final determination of fair value.

Luther Burbank’s unaudited condensed consolidated statement of operations for the three months ended December 31, 2022 was derived by subtracting the historical unaudited condensed consolidated statement of operations for the nine months ended September 30, 2022 appearing in Luther Burbank’s Quarterly Report on Form 10-Q filed on November 4, 2022 from the audited consolidated statement of operations for the fiscal year ended December 31, 2022. Given the different fiscal year ends Washington Federal and Luther Burbank, the Luther Burbank historical unaudited condensed consolidated statement of operations for the twelve months ended September 30, 2022 was derived by subtracting the historical unaudited condensed consolidated statement of operations for the nine months ended September 30, 2021 appearing in Luther Burbank’s Quarterly Report on Form 10-Q filed on November 5, 2021 from the audited consolidated statement of operations for the fiscal year ended December 31, 2021 and adding the historical unaudited condensed consolidated statement of operations for the nine months ended September 30, 2022 appearing in Luther Burbank’s Quarterly Report on Form 10-Q filed on November 4, 2022.

All dollar amounts presented within these Notes to Unaudited Pro Forma Condensed Combined Financial Statements are in thousands, except per share data and share amounts.

Washington Federal price per common share as of February 24, 2023 |  | $ | 35.33 |
Purchase price determination of hypothetical Washington Federal shares issued to Luther Burbank shareholders |  | $ | 605,984 |

For the purposes of the transaction accounting adjustments, the final purchase price to be paid by Washington Federal in shares of Washington Federal common stock upon the completion of the acquisition will be determined based on the closing price of Washington Federal common stock on the closing date and the number of issued and outstanding shares of Luther Burbank common stock immediately prior to the effective time. Actual adjustments may differ from the amounts reflected in the pro forma financial information, and the differences may be material.

The final purchase price for purposes of the transaction accounting adjustments could significantly differ from the amounts presented in the pro forma financial information due to movements in the trading price of Washington Federal common stock prior to the closing date of the acquisition. A sensitivity analysis related to the fluctuation in the trading price of Washington Federal common stock was performed to assess the impact a hypothetical change of up to 20% on the trading price of Washington Federal common stock on the NASDAQ on February 24, 2023 would have on the preliminary purchase price and goodwill as of the closing date of the merger.

The capital stock of Washington Federal does not represent or constitute a deposit account and is not insured by the FDIC.

The following description of the Washington Federal capital stock does not purport to be complete and is qualified in all respects by reference to Washington Federal’s articles, the Washington Federal bylaws and the WBCA.

Washington Federal Common Stock

Each share of Washington Federal common stock is entitled to one vote on all matters submitted to a vote at any meeting of shareholders. Holders of Washington Federal common stock are entitled to receive dividends as may be declared by the Washington Federal board out of funds legally available therefore and, upon liquidation, to receive pro rata all assets, if any, of Washington Federal available for distribution after the payment of creditors. Holders of Washington Federal common stock have no preemptive rights to subscribe for any additional securities of any class that Washington Federal may issue, nor any conversion, redemption or sinking fund rights. Each holder of Washington Federal common stock is entitled to one vote for each share held of record. Shareholders of Washington Federal are permitted to cumulate their votes with respect to the election of directors. Cumulative voting entitles each shareholder to cast a number of votes in the election of directors equal to the number of shares of common stock held by the shareholder multiplied by the number of directors to be elected, and to distribute such votes among one or more of the nominees to be elected. The Washington Federal board is divided into three classes, with directors serving staggered three-year terms, and currently consists of 10 directors, with two spots vacant. The rights and privileges of holders of Washington Federal common stock are subject to any preferences that the Washington Federal board may set for any series of Washington Federal preferred stock that Washington Federal may issue in the future.

Washington Federal Preferred Stock

Under the Washington Federal articles, Washington Federal may issue shares of Washington Federal preferred stock in one or more series, as may be determined by the Washington Federal board. The Washington Federal board may fix the number of shares to be included in each series and the designation, powers, preferences and rights of the shares of each such series and any qualifications, limitations or restrictions thereof, and may decrease the number of shares of any series, but not below the number of shares of such series then outstanding, without any further vote or action by the shareholders. In addition, any shares of Washington Federal preferred stock may have class or series voting rights. Under certain circumstances, the issuance of shares of Washington Federal preferred stock, or merely the existing authorization of the Washington Federal board to issue shares of Washington Federal preferred stock, may tend to discourage or impede a merger or other change in control of Washington Federal. The number of shares of preferred stock to be issued, its par or face value, voting powers, designations, preferences, interest rate, limitations, restrictions and relative rights would be determined from time to time by resolution of the Washington Federal board.

On February 8, 2021, in connection with an underwritten public offering, Washington Federal issued 300,000 shares of Series A preferred stock. The public offering consisted of the issuance and sale of 12,000,000 depositary shares, each representing a 1/40th interest in a share of the Series A preferred stock, at a public offering price of $25.00 per depositary share. Holders of the depositary shares are entitled to all proportional rights and preferences of the Series A preferred stock (including dividend, voting, redemption and liquidation rights). The depositary shares are traded on the NASDAQ under the symbol “WAFDP.” The Series A preferred

Dividends

Under the WBCA, a corporation may make a distribution in cash or in property to its shareholders upon the authorization of its board of directors unless, after giving effect to this distribution, (a) the corporation would not be able to pay its debts as they become due in the usual course of business or (b) the corporation’s total assets would be less than the sum of its total liabilities plus, unless the articles of incorporation permit otherwise, the amount that would be needed if the corporation were to be dissolved at the time of the distribution to satisfy the preferential rights of shareholders whose preferential rights are superior to those receiving the distribution.

Anti-Takeover Considerations

Washington law, the Washington Federal articles and the Washington Federal bylaws contain certain provisions which may have the effect of discouraging transactions that involve an actual or threatened change of control of Washington Federal. These provisions of the Washington Federal articles and the Washington Federal bylaws include, among others, the authorization of directors to fill vacancies on the board, the procedures for calling special meetings of shareholders, the requirement that any shareholder action by written consent must be unanimous and a board of directors divided into three classes, with the members of each class of directors serving staggered three-year terms. See the section entitled “Comparison of the Rights of Shareholders” beginning on page 137.

##### Table of Contents

the WBCA, Washington Federal directors may be removed only for cause by an affirmative vote of not less than a majority of the votes eligible to be cast by shareholders at a meeting of shareholders called expressly for such purpose, provided that a director may not be removed if the number of votes sufficient to elect the director under cumulative voting is voted against the director’s removal. The WBCA provides that if a director is elected by a voting group of shareholders, only the shareholders of that voting group may participate in the vote to remove the director.

The CGCL also provides that any director may be removed by a court for fraudulent or dishonest acts, or gross abuse of authority, if shareholders holding at least 10% of the number of outstanding shares of any class bring suit. If any director is removed by the shareholders, the shareholders may elect new directors at the same meeting.

Indemnification of Directors and Officers

Washington Federal

The WBCA generally permits corporations to indemnify its directors for actions taken in good faith and which the individual reasonably believed, in the case of conduct in the individual’s official capacity, to be in the best interests of the corporation, and in all other cases, that the individual’s conduct was at least not opposed to the corporation’s best interests. In the case of a criminal proceeding, the individual must not have had any reasonable cause to believe the conduct was unlawful. A director may not be indemnified in connection with a proceeding by or in the right of the corporation in which the director was found liable to the corporation, or a proceeding in which the director was found to have improperly received a personal benefit. The WBCA provides for mandatory indemnification of directors for reasonable expenses incurred when the indemnified party is wholly successful in the defense of the proceeding. A corporation may indemnify officers to the same extent as directors. Washington law permits a director of a corporation who is a party to a proceeding to apply to the courts for indemnification or advance of expenses, unless the articles of incorporation provide otherwise, and the court may order indemnification or advancement of expenses under certain circumstances set forth in the statute. Washington law further provides that a corporation may, if authorized by its articles of incorporation or a bylaw or resolution adopted or ratified by the shareholders, provide indemnification in addition to that provided by statute, subject to certain conditions set forth in the statute.

The Washington Federal articles provide that Washington Federal will indemnify and hold harmless each individual who is or was serving as a director or officer of Washington Federal with respect to any proceeding resulting from such person’s service to Washington Federal to the fullest extent authorized by law. The rights to indemnification provided by the Washington Federal bylaws includes the right to be paid, in advance of in advance of a proceeding’s final disposition, expenses incurred in defending that proceeding.

Luther Burbank

The CGCL provides that a corporation may indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation to procure a judgment in its favor) by reason of the fact that he or she is or was a director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (“agents”), against expenses (including attorneys’ fees), judgments, fines, settlements, and other amounts actually and reasonably incurred in connection with the proceeding if that person acted in good faith and in a manner the person reasonably believed to be in the best interests of the corporation and, in the case of a criminal proceeding, had no reasonable cause to believe the conduct of the person was unlawful. A similar standard is applicable in the case of actions by or in the right of the corporation, except that indemnification extends only to expenses actually and reasonably incurred in connection with the defense or settlement of such action.

The CGCL provides that any indemnification must be made by the corporation only as authorized in the specific case upon a determination that indemnification is proper in the circumstances because the person has met the applicable standard of conduct. Such determination must be made (i) by a majority vote of a quorum consisting of directors who are not parties to such proceeding, (ii) if such a quorum of directors is not obtainable, by independent legal counsel in a written opinion, (iii) by the affirmative vote of a majority of the shares represented and voting at a duly held meeting at which a quorum is present, with the shares owned by the person to be indemnified not being entitled to vote thereon, or (iv) by the court in which the proceeding is or was pending upon application made by the corporation or the person to be indemnified or the attorney or other person rendering services in connection with the defense, whether or not the application by the person to be indemnified, attorney or other person is opposed by the corporation.

The CGCL provides that it is not exclusive of other indemnification that may be granted by a corporation’s bylaws, disinterested director vote, shareholder vote, agreement or otherwise.

141

##### Table of Contents

California law does not allow Luther Burbank to indemnify its agents for: (1) any claim, issue or matter as to which the person has been adjudged to be liable to the corporation in the performance of that person’s duty to the corporation and its shareholders, unless and only to the extent that the court in which the proceeding is or was pending will determine upon application that, in view of all the circumstances of the case, the person is fairly and reasonably entitled to indemnity for expenses and then only to the extent that the court determines; (2) any amounts paid in settling or otherwise disposing of a pending action without court approval; and (3) any expenses incurred in defending a pending action which is settled or otherwise disposed of without court approval. California law provides that to the extent that an agent of a corporation has been successful on the merits in defense of any related proceeding or in defense of any claim, issue, or matter therein, the agent will be indemnified against expenses actually and reasonably incurred by the agent.

The Luther Burbank articles provide that Luther Burbank will indemnify and hold harmless each individual who is or was serving as a director of officer of Luther Burbank with respect to any proceeding resulting from such person’s service to Luther Burbank to the fullest extent authorized by law.

Amendments to Articles of Incorporation and Bylaws

Washington Federal

The Washington Federal bylaws may be amended by the affirmative vote of a majority of the Washington Federal board or by affirmative vote of the holders of a majority of the votes cast by shareholders of the Washington Federal at an annual or special meeting of the shareholders; provided that the Washington Federal board may not alter, amend or repeal any bylaw that Washington Federal shareholders have expressly provided, in altering, amending or repealing such bylaw.

Washington Federal

Neither the Washington Federal articles nor the Washington Federal bylaws contain a provision regarding shareholder action by written consent.

Luther Burbank

Transactions with Related Persons, Share Re-classifications and Re-capitalizations

Washington Federal

The Washington Federal articles do not impose voting requirements on mergers, asset transfers or securities issuances between or among related persons or upon share re-classifications or re-capitalizations beyond those imposed by the WBCA.

Luther Burbank

The Luther Burbank articles do not impose voting requirements on mergers, asset transfers or securities issuances between or among related persons or upon share re-classifications or re-capitalizations beyond those imposed by the CGCL.

Dividends

Washington Federal

Under the WBCA, generally a corporation may not pay a dividend if, after giving effect to the dividend, the corporation would be unable to pay its liabilities as they become due in the ordinary course of business or the corporation’s total assets would be less than the sum of its total liabilities plus (with some exceptions) the amount that would be needed, if the corporation were to be dissolved at the time of the dividend payment, to satisfy the dissolution preferences of senior equity securities.

Washington Federal’s ability to pay dividends is subject to rules and policies of the Federal Reserve. It is the policy of the Federal Reserve that bank holding companies should pay cash dividends only out of income available over the past year and only if prospective earnings retention is consistent with the company’s expected future needs and financial condition. Capital rules adopted by the Federal Reserve, effective January 2015, may limit Washington Federal’s ability to pay dividends if Washington Federal fails to meet certain requirements under the rules. In addition, if Washington Federal does not or is unable to pay quarterly dividends on Washington Federal’s Series A Preferred Stock, it may not pay a dividend to the holders of Washington Federal common stock.

The Washington Federal bylaws permit the Washington Federal board to declare dividends out of funds legally available for dividends. On February 14, 2023, the Washington Federal board declared a quarterly cash dividend on the Washington Federal Series A preferred stock of $12.1875 per share, payable on the first business day following April 15, 2023 to shareholders of record as of March 31, 2023. On December 2, 2022, Washington Federal paid a regular quarterly cash dividend on the Washington Federal common stock of $0.24 per share. Although Washington Federal anticipates that it will continue to pay quarterly cash dividends, the payment and amount of future dividends remains with the discretion of the Washington Federal board and there can be no assurance that the payment of such dividends will continue or that the amount of such dividends will not be reduced.

Luther Burbank

Under the CGCL, a corporation cannot make any distribution to its shareholders unless its board of directors has determined in good faith either (i) the amount of retained earnings of the corporation immediately prior to the distribution equals or exceeds the sum of (a) the amount of the proposed distribution plus (b) the preferential dividends arrears amount; or (ii) immediately after the distribution, the value of the corporation’s assets would equal or exceed the sum of its total liabilities, plus any preferential rights amount.

Further, it is the policy of the Federal Reserve that bank holding companies, such as Luther Burbank, should generally pay dividends on common stock only out of income available over the past year, and only if

145

##### Table of Contents

prospective earnings retention is consistent with the organization’s expected future needs and financial condition. It is also the Federal Reserve’s policy that bank holding companies should not maintain dividend levels that undermine their ability to be a source of strength to their banking subsidiaries.

The Luther Burbank bylaws permit the Luther Burbank board to declare dividends out of funds legally available for dividends. A quarterly dividend of $0.12 per share was declared during each quarter of 2022.

Shareholders’ Rights of Dissent and Appraisal

Washington Federal

Under Washington law, a shareholder is entitled to dissent from, and obtain payment of the fair value of the shareholder’s shares only in the event of, any of the following corporate acts: (i) consummation of a plan of merger to which the corporation is a party if shareholder approval is required and the shareholder is entitled to vote on the merger or if the corporation is a subsidiary that is merged with its parent; (ii) consummation of a plan of share exchange to which the corporation is a party as the corporation whose shares will be acquired, if the shareholder is entitled to vote on the plan; (iii) consummation of a sale or exchange of all or substantially all of the property of the corporation other than in the usual and regular course of business if the shareholder is entitled to vote on the sale or exchange, including a sale in dissolution, unless the sale is pursuant to a court order or a sale for cash pursuant to a plan by which all or substantially all of the net proceeds will be distributed to Washington Federal shareholders within one year; (iv) an amendment of the articles of incorporation if the amendment effects the redemption or cancellation of all of the shareholder’s shares in exchange for cash or other consideration other than shares of the corporation; (v) an election by a corporation to become or cease to become a social purpose corporation, which has become effective, to which the corporation is a party if shareholder approval was required for the election; (vi) an amendment of a social purpose corporation’s articles of incorporation that would materially change a purpose of the corporation; (vii) any corporate action taken pursuant to a shareholder vote to the extent the articles of incorporation, bylaws or a resolution of the board of directors provides that voting or nonvoting Washington Federal shareholders are entitled to dissent and obtain payment for their shares; or (viii) a plan of entity conversion in the case of a conversion of a domestic corporation to a foreign corporation, which has become effective, to which the domestic corporation is a party as the converting entity, if: (a) the shareholder was entitled to vote on the plan, and (b) the shareholder does not receive shares in the surviving entity that have terms as favorable to the shareholder in all material respects and that represent at least the same percentage interest of the total voting rights of the outstanding shares of the surviving entity as the shares held by the shareholder before the conversion.

Luther Burbank

Under the CGCL, shareholders are generally entitled to dissent from a merger or consolidation and obtain payment of the fair value of their shares when a merger or consolidation occurs. However, the CGCL provides that appraisal rights are not available for shares that are listed on a national securities exchange where the merger consideration is stock of a publicly traded corporation. Luther Burbank’s common stock is traded on a national security exchange and the merger consideration, comprised of Washington Federal’s common stock, is also traded on a national securities exchange. As such, Luther Burbank’s shareholders are not entitled to appraisal rights in connection with the merger.

Anti-Takeover Provisions and Other Shareholder Protections

Washington Federal

Chapter 23B.09 of the WBCA prohibits corporations that have a class of voting stock registered under the Exchange Act from engaging in any “significant business transaction” (defined to include mergers or consolidations, certain sales, termination of 5% or more of a corporation’s employees, sales of assets, liquidation or dissolution and other specified transactions) with a person or group that beneficially owns 10% or more of a corporation’s outstanding voting stock, which we refer to as an acquiring person, for a period of five years after such person or group becomes an acquiring person, unless the significant business transaction or the acquisition by which such person became an acquiring person is approved prior to the time the person became an acquiring person by a majority vote of the board of directors, or the significant business transaction is approved by a majority vote of the board of directors and approved at an annual or special meeting of shareholders by the affirmative vote of at least two-thirds of the outstanding voting shares (excluding shares beneficially owned by or under the voting control of the acquiring person). The Washington Federal articles include certain provisions that could make more difficult the acquisition of Washington Federal by means of a tender offer, a proxy contest, merger or otherwise.

Luther Burbank

The CGCL provides that most business combinations, including mergers, consolidations and sales of substantially all of the assets of a California corporation, must be approved by the vote of the holders of at least a majority of the outstanding shares of common stock and any other affected class of stock of such corporation. The articles or bylaws of a California corporation may, but are not required to, set a higher standard for approval of such transactions. The Luther Burbank articles and the Luther Burbank bylaws do not impose a higher standard of approval for such transactions.

Section 1101 of the CGCL requires that, in a merger of a corporation with a shareholder (or its affiliate) who holds more than 50% but less than 90% of the corporation’s common stock, the other shareholders of the corporation must receive common stock in the transaction, unless all the corporation’s shareholders consent to the transaction.

Section 1203 of the CGCL also provides that, except in certain circumstances, when a tender offer or a proposal for a reorganization or sale of assets is made by an interested party (generally a controlling or managing party of the corporation), the interested party must provide the other shareholders with a written opinion as to the fairness of the consideration to be paid to the shareholders. Furthermore, if a tender of shares or a vote is sought pursuant to an interested party’s proposal and a later proposal is made by another party at least 10 days prior to the date of acceptance of the interested party’s proposal, the shareholders must be informed of the later offer and be afforded a reasonable opportunity to withdraw their vote, consent or proxy, and to withdraw any tendered shares.

In addition, the authorization of preferred stock, which is intended primarily as a financing tool and not as a defensive measure against takeovers, may potentially be used by Luther Burbank’s board to make more difficult uninvited attempts to acquire control of Luther Burbank, as it could be issued easily and quickly, could adversely affect the rights of holders of Luther Burbank common stock and could be issued with terms calculated to delay or prevent a change in control of Luther Burbank or make removal of the members of the Luther Burbank board or management more difficult.

Forum Selection Bylaw

Washington Federal

The Washington Federal bylaws do not feature a forum selection bylaw.

147

##### Table of Contents

Luther Burbank

The Luther Burbank bylaws feature a forum selection bylaw, which provides that unless Luther Burbank consents in writing to the selection of an alternative forum, the state or federal court of general jurisdiction in the county where Luther Burbank maintains its principal office will be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of Luther Burbank, (ii) any action asserting a claim for breach of a fiduciary duty owed by any director, officer, employee, or agent of Luther Burbank to Luther Burbank or Luther Burbank’s shareholders, (iii) any action asserting a claim arising pursuant to any provision of the CGCL, the Luther Burbank articles, or the Luther Burbank bylaws, or (iv) any action asserting a claim governed by the internal affairs doctrine, in each case subject to said courts having personal jurisdiction over the indispensable parties named as defendants therein.

Unless Luther Burbank consents in writing to the selection of an alternative forum, the federal district courts of the United States of America will be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act.

The Exchange Agent shall accept such Certificates or Book-Entry Shares upon compliance with such reasonable terms and conditions as the Exchange Agent may impose consistent with the notice and form of letter of transmittal to effect an orderly exchange thereof in accordance with normal exchange practices.

The Exchange Agent and WAFD, as the case may be, shall not be obligated to deliver a certificate or certificates or book-entry shares representing shares of WAFD Common Stock to which a holder of LBC Common Stock would otherwise be entitled as a result of the Merger until such holder surrenders the Certificate or Certificates representing the shares of LBC Common Stock for exchange as provided in this Section 3.02, or, in default thereof, an appropriate affidavit of loss and indemnity agreement and/or a bond in an amount as may be reasonably required in each case by WAFD. If any certificates evidencing shares of WAFD Common Stock are to be issued in a name other than that in which the Certificate evidencing LBC Common Stock surrendered in exchange therefore is registered, it shall be a condition of the issuance thereof that the Certificate so surrendered shall be properly endorsed or accompanied by an executed form of assignment separate from the Certificate and otherwise in proper form for transfer and that the Person requesting such exchange pay to the Exchange Agent any transfer or other Tax required by reason of the issuance of a certificate for shares or book-entry shares of WAFD Common Stock in any name other than that of the registered holder of the Certificate or Book-Entry Shares surrendered or otherwise establish to the satisfaction of the Exchange Agent that such Tax has been paid or is not payable.

(f) Unclaimed Merger Consideration. The exchange of shares of WAFD Common Stock for the Merger Consideration as provided in this Section 3.02 shall be administered by the Exchange Agent until such time as any unclaimed portion thereof is required to be delivered to a public official pursuant to applicable abandoned property, escheat or similar laws. Neither the Exchange Agent nor any party to this Agreement shall be liable to any holder of stock represented by any Certificate or Book-Entry Share for any consideration paid to a public official pursuant to applicable abandoned property, escheat or similar laws. The Exchange Agent shall be entitled to rely upon the stock transfer books of LBC to establish the identity of those Persons entitled to receive the consideration specified in this Agreement, which books shall be conclusive (absent manifest error) with respect thereto. In the event of a dispute with respect to ownership of stock represented by any Certificate or Book-Entry Share, the Exchange Agent shall be entitled to deposit any consideration represented thereby in escrow with an independent third party and thereafter be relieved with respect to any claims thereto.

3.03 Rights as Shareholders. At the Effective Time, holders of LBC Common Stock shall cease to be, and shall have no rights as, shareholders of LBC other than to receive the consideration provided for under this Article III.

3.04 No Fractional Shares. Notwithstanding any other provision of this Agreement, neither certificates nor scrip for fractional shares of WAFD Common Stock shall be issued in the Merger.

No such holder shall be entitled to dividends, voting rights or any other rights in respect of any fractional share.

A-13

##### Table of Contents

sale of WAFD Common Stock for fair value received shall not be deemed a reclassification, recapitalization, split-up, combination, exchange of shares or readjustment, stock dividend or distribution, stock split (including a reverse stock split), issuer tender or exchange offer or other transaction in WAFD Common Stock having such effect.

3.06 Withholding Rights. WAFD (through the Exchange Agent, if applicable) shall be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement to any holder of shares of LBC Common Stock or LBC Restricted Stock such amounts as WAFD is required under the Code or any state, local or foreign Tax law or regulation thereunder to deduct and withhold with respect to the making of such payment. Any amounts so withheld shall be timely remitted to the applicable Governmental Authority and shall be treated for all purposes of this Agreement as having been paid to the holder of LBC Common Stock in respect of which such deduction and withholding was made by WAFD. The parties shall cooperate in good faith to minimize to the extent permissible the amount of any deduction or withholding, including providing any certificates or forms that are reasonably requested to establish an exemption from (or reduction in) any such deduction or withholding.

3.07 LBC Restricted Stock and LBC Restricted Stock Units

(a) LBC shall take all necessary action, if any, and without any action on the part of the holder thereof and consistent with the terms of the LBC Equity Plan, to cause each outstanding award of LBC Restricted Stock and LBC Restricted Stock Units (other than the LBC Restricted Stock and LBC Restricted Stock Units held by Continuing Employees) to vest in full, effective as of the Effective Time. At the Effective Time, each share of LBC Restricted Stock and each LBC Restricted Stock Unit (other than LBC Restricted Stock and LBC Restricted Stock Units held by Continuing Employees) shall be converted into, and shall be canceled in exchange for, the right to receive (x) a number of shares of WAFD Common Stock equal to the number of shares of LBC Restricted Stock or LBC Restricted Stock Units, as applicable, multiplied by the Exchange Ratio, provided that any fractional shares of WAFD Common Stock shall be treated as set forth in Section 3.04 and (y) an amount in cash equal to any accrued dividends or dividend equivalents that are payable in cash pursuant to the terms of the LBC Restricted Stock or LBC Restricted Stock Unit, as applicable. If the holder of such LBC Restricted Stock or LBC Restricted Stock Unit, as applicable, does not satisfy the applicable Taxes required to be withheld with respect to the vesting and settlement of such LBC Restricted Stock or LBC Restricted Stock Unit, as applicable, on or before the Closing Date, then the number of shares of WAFD Common Stock delivered in respect of the LBC Restricted Stock or LBC Restricted Stock Unit, as applicable, will be reduced by a number of shares of WAFD Common Stock with a fair market value, based on the closing price of a share of WAFD Common Stock on the Closing Date, equal to any Taxes required to be withheld with respect to the vesting and settlement of such LBC Restricted Stock or LBC Restricted Stock Unit, as applicable (and for the avoidance of doubt, any such shares will be for the benefit of such holder to satisfy its Tax withholding requirements). Notwithstanding the foregoing, any LBC Restricted Stock Unit that constitutes nonqualified deferred compensation subject to Section 409A of the Code and that may not be settled at the Effective Time without triggering a Tax or penalty under Section 409A of the Code shall be fully vested in accordance with this Section 3.07(a) but otherwise treated as a LBC Restricted Stock Unit held by a Continuing Employee in accordance with Section 3.07(b) and shall otherwise be settled in accordance with its terms.

(b) At the Effective Time, each share of LBC Restricted Stock and each LBC Restricted Stock Unit held by a Continuing Employee (i) to the extent expressly assumed by WAFD, (A) shall automatically and without any action on the part of the holder thereof, cease to represent a share of LBC Restricted Stock or a LBC Restricted Stock Unit and shall be substituted with a share of WAFD restricted stock or a WAFD restricted stock unit, as applicable, with terms substantially similar or better to the terms and conditions (including the same vesting terms, change in control vesting rights and rights to dividend equivalents) as were applicable to such share of LBC Restricted Stock or LBC Restricted Stock Unit, as applicable, immediately prior to the Effective Time and (B) the number of shares of WAFD Common Stock subject to each such share of LBC Restricted Stock or each LBC Restricted Stock Unit shall be equal to the product (rounded to the nearest whole number) of (x) the number of shares of LBC Common Stock subject to such LBC Restricted Stock or LBC Restricted Stock Unit, as

A-14

##### Table of Contents

applicable, immediately prior to the Effective Time multiplied by (y) the Exchange Ratio, or (ii) to the extent not expressly assumed by WAFD, shall be treated in the same manner as awards of LBC Restricted Stock and LBC Restricted Stock Units pursuant to Section 3.07(a) above.

3.08 Reservation of Shares. Prior to the Closing, the WAFD Board shall reserve for issuance a sufficient number of shares of WAFD Common Stock (i) for the purpose of issuing its shares in exchange for shares of LBC Common Stock in the Merger and (ii) to convert the unvested LBC Restricted Stock and unvested LBC Restricted Stock Units into shares of WAFD Common Stock.

(j) Regulatory Matters.

(i) Since October 1, 2019, WAFD and each of its Subsidiaries has duly filed with the appropriate bank regulatory authorities in substantially correct form the monthly, quarterly and annual reports required to be filed under applicable laws and regulations, and such reports were in all material respects complete and accurate and in compliance with the requirements of applicable laws and regulations.

(iii) Neither WAFD nor any its Subsidiaries has been advised by, and does not have any Knowledge of facts which would reasonably be expected to give rise to an advisory notice by, any Governmental Authority that such Governmental Authority is contemplating issuing or requesting (or is considering the appropriateness of issuing or requesting) any such order, decree, directive, agreement, memorandum of understanding, commitment letter, supervisory letter or similar submission or any request for the adoption of any policy, procedure or board resolution.

(iv) (A) No Governmental Authority has initiated since September 30, 2019 or has pending any proceeding, enforcement action or, to WAFD’s Knowledge, investigation or inquiry into the business, operations, policies, practices or disclosures of WAFD or any of its Subsidiaries (other than normal examinations conducted by a Governmental Authority in the ordinary course of the business of WAFD or the applicable Subsidiary), or, to WAFD’s Knowledge, threatened any of the foregoing, and (B) there is no unresolved violation, criticism, comment or exception by any Governmental Authority with respect to any report or statement relating to any examinations or inspections of WAFD or its Subsidiaries, except in each case in subparagraphs (A) and (B), that did not have a Material Adverse Effect.

6.07 Acquisition Proposals.

(a) LBC agrees that it shall, and shall direct and use its reasonable best efforts to cause its affiliates, directors, officers, employees, agents and representatives (including, without limitation, any investment banker, financial advisor, attorney, accountant or other representative retained by it) (all of the foregoing, collectively, “Representatives”) to, immediately cease any discussions or negotiations with any other parties that may be ongoing with respect to the possibility or consideration of any Acquisition Proposal, and will use its reasonable best efforts to enforce any confidentiality or similar agreement relating to any Acquisition Proposal, including by requesting the other party to promptly return or destroy any Confidential Information previously furnished by or on behalf of LBC or any of its Subsidiaries thereunder and by specifically enforcing the terms thereof in a court of competent jurisdiction. From the date of this Agreement through the Effective Time, neither LBC nor any of its Subsidiaries shall, and shall cause their respective directors, officers or employees or any Representative retained by them not to, directly or indirectly through another Person, (i) solicit, initiate or encourage (including by way of furnishing information or assistance), or take any other action designed to facilitate or that is likely to result in, any inquiries or the making of any proposal or offer that constitutes, or is reasonably likely to lead to, any Acquisition Proposal, (ii) provide any Confidential Information or data to any Person relating to any Acquisition Proposal, (iii) participate in any discussions or negotiations regarding any Acquisition Proposal, (iv) waive, terminate, modify or fail to enforce any provision of any contractual “standstill” or similar obligations of any Person other than WAFD or its Affiliates, (v) approve or recommend, propose to approve or recommend, or execute or enter into, any letter of intent, agreement in principle, merger agreement, asset purchase agreement or share exchange agreement, option agreement or other similar agreement related to any Acquisition Proposal or

A-47

##### Table of Contents

propose to do any of the foregoing, or (vi) make or authorize any statement, recommendation or solicitation in support of any Acquisition Proposal; provided, however, that prior to the date of the LBC Meeting, if the LBC Board determines in good faith, after consulting with its outside legal and financial advisors, that the failure to do so would more likely than not result in a breach of the LBC Board’s fiduciary duties under applicable law, LBC may, in response to a bona fide, written Acquisition Proposal not solicited in violation of this Section 6.07(a) that the LBC Board determines in good faith constitutes a Superior Proposal, subject to providing two (2) Business Days prior written notice of its decision to take such action to WAFD and identifying the Person making the proposal and all the material terms and conditions of such proposal and compliance with Section 6.07(b), (1) furnish information with respect to itself to any Person making such a Superior Proposal pursuant to a customary confidentiality agreement (as determined by LBC after consultation with its outside counsel) on terms no more favorable to such Person than the terms contained in the Confidentiality Agreement are to WAFD, and (2) participate in discussions or negotiations regarding such a Superior Proposal. For purposes of this Agreement, the term “Acquisition Proposal” means any inquiry, proposal or offer, filing of any regulatory application or notice or disclosure of an intention to do any of the foregoing from any Person relating to any (w) direct or indirect acquisition or purchase of a business that constitutes 25% or more of the total revenues, net income, assets or deposits of LBC and its Subsidiaries taken as a whole, (x) direct or indirect acquisition or purchase of any class of Equity Securities representing 25% or more of the voting power of LBC or LB Savings, (y) tender offer or exchange offer that if consummated would result in any person beneficially owning 25% or more of any class of Equity Securities of LBC or LB Savings or (z) merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction involving LBC or LB Savings, other than the Transaction contemplated by this Agreement. For purposes of this Agreement, the term “Superior Proposal” means any bona fide written proposal made by a third party to acquire, directly or indirectly, including pursuant to a tender offer, exchange offer, merger, consolidation, business combination, recapitalization, liquidation, dissolution or similar transaction, for consideration consisting of cash and/or securities, more than 50% of the combined voting power of the shares of LBC Common Stock then outstanding or all or substantially all of LBC’s consolidated assets, which the LBC Board determines in good faith, after taking into account all legal, financial, regulatory and other aspects of the proposal and the person making the proposal (including any break-up fees, expense reimbursement provisions and conditions to consummation), and after consulting with LBC’s financial advisor (which shall be a recognized investment banking firm) and outside counsel, (i) is more favorable from a financial point of view to its shareholders than the Merger, (ii) is reasonably likely to be consummated on the terms set forth, and (iii) for which financing, to the extent required, is then committed or which, in the good faith judgment of the LBC Board, is reasonably likely to be obtained by such third party.

(b) In addition to the obligations of LBC set forth in Section 6.07(a), LBC shall promptly (within 24 hours) advise WAFD orally and in writing of its receipt of any Acquisition Proposal and keep WAFD reasonably informed, on a current basis, of the continuing status thereof, including the material terms and conditions thereof and any material changes thereto, and shall contemporaneously provide to WAFD all materials provided to or made available to any third party pursuant to this Section 6.07 which were not previously provided to WAFD.

(c) LBC agrees that any violation of the restrictions set forth in this Section 6.07 by any Representative of LBC or its Subsidiaries shall be deemed a breach of this Section 6.07 by LBC.

(d) Nothing contained in this Agreement shall prevent LBC or the LBC Board from complying with Rules 14d-9 and 14e-2 under the Exchange Act with respect to an Acquisition Proposal.

(e) The parties hereto agree that irreparable damage would occur in the event any of the restrictions set forth in Section 6.07(a) were violated by LBC, its Subsidiaries or any Representative of LBC or its Subsidiaries. It is accordingly agreed that WAFD shall be entitled to an injunction or injunctions to prevent breaches of Section 6.07 and to enforce specifically the terms and provisions thereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which WAFD is entitled at law or in equity. In the event attorneys’ fees or other costs are incurred to secure performance of any of the obligations herein provided for, or to

A-48

##### Table of Contents

establish damages for the breach thereof, or to obtain any other appropriate relief, whether by way of prosecution or defense, WAFD shall be entitled to recover reasonable attorneys’ fees and costs incurred therein.

6.08 Certain Policies. Effective as of the Effective Time, and provided that each party has confirmed in writing that all conditions to its obligations to effect the Merger have been satisfied or waived and that it is prepared to effect the Merger, upon the request of WAFD, LBC shall, and shall cause its Subsidiaries to, consistent with GAAP and applicable banking laws and regulations, use their commercially reasonable best efforts to promptly modify or change their Loan, OREO, accrual, reserve, Tax, litigation and real estate valuation policies and practices (including loan classifications and levels of reserves) so as to be applied on a basis that is consistent with that of WAFD; provided, however, that no such modification or change made by LBC or any of its Subsidiaries pursuant to this Section 6.08 shall constitute or be deemed to be a breach, violation of or failure to satisfy any representation, warranty, covenant, agreement, condition or other provision of this Agreement or otherwise be considered in determining whether any such breach, violation or failure to satisfy shall have occurred. The recording of any such adjustments shall not be deemed to imply any misstatement of previously furnished financial statements or information and shall not be construed as concurrence of LBC or its management with any such adjustments.

6.09 Nasdaq Listing. WAFD shall, as promptly as practicable, file all documents, take all actions reasonably necessary and otherwise use its reasonable best efforts to list, prior to the Effective Date, on the Nasdaq the shares of WAFD Common Stock to be issued to the LBC shareholders (i) as the Merger Consideration in connection with the Merger and (ii) in connection with the conversion of the unvested restricted shares of LBC Common Stock into shares of WAFD Common Stock.

6.10 Indemnification.

(a) From and after the Effective Time through the sixth (6th) anniversary of the Effective Time, WAFD and the Surviving Corporation (each an “Indemnifying Party”) shall indemnify and hold harmless each present and former director, officer and employee of LBC or a LBC Subsidiary, as applicable, determined as of the Effective Time (the “Indemnified Parties”) against any costs or expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages or liabilities incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of matters existing or occurring, at or prior to the Effective Time, whether asserted or claimed prior to, at or after the Effective Time, arising in whole or in part out of or pertaining to the fact that he or she was a director, officer, employee, fiduciary or agent of LBC or any LBC Subsidiary or is or was serving at the request of LBC or any LBC Subsidiary as a director, officer, employee, fiduciary or agent of another corporation, partnership, joint venture, trust or other enterprise, including, without limitation, matters related to the negotiation, execution and performance of this Agreement or consummation of the Transaction, to the fullest extent which such Indemnified Parties would be entitled under the LBC Articles and the LBC Bylaws or any agreement, arrangement or understanding which has been set forth on Schedule 6.10(a), in each case as in effect on the date hereof. WAFD shall also cause the Surviving Corporation to advance expenses as incurred by such Indemnified Parties to the same extent as such persons are entitled to advancement of expenses as of the date of this Agreement by LBC pursuant to the LBC Articles and the LBC Bylaws or any agreement, arrangement or understanding which has been set forth on Schedule 6.10(a), in each case as in effect on the date hereof.

(b) Any Indemnified Party wishing to claim indemnification under this Section 6.10, upon learning of any such claim, action, suit, proceeding or investigation, shall promptly notify the Indemnifying Party, but the failure to so notify shall not relieve the Indemnifying Party of any liability it may have to such Indemnified Party if such failure does not actually prejudice the Indemnifying Party. In the event of any such claim, action, suit, proceeding or investigation (whether arising before or after the Effective Time), (i) the Indemnifying Party shall have the right to assume the defense thereof and the Indemnifying Party shall not be liable to such Indemnified Parties for any legal expenses of other counsel or any other expenses subsequently incurred by such Indemnified Parties in connection with the defense thereof, except that if the Indemnifying Party elects not to assume such defense or counsel for the Indemnified Parties advises that there are issues which raise conflicts of interest

A-49

##### Table of Contents

between the Indemnifying Party and the Indemnified Parties that make joint representation inappropriate, the Indemnified Parties may retain counsel which is reasonably satisfactory to the Indemnifying Party, and the Indemnifying Party shall pay, promptly as statements therefor are received, the reasonable fees and expenses of such counsel for the Indemnified Parties (which may not exceed one firm in any jurisdiction unless the Indemnified Parties have conflicts of interest), (ii) the Indemnified Parties will cooperate in the defense of any such matter, (iii) the Indemnifying Party shall not be liable for any settlement effected without its prior written consent, which consent shall not be unreasonably withheld, conditioned or delayed, and (iv) the Indemnifying Party shall have no obligation hereunder in the event that a federal or state banking agency or a court of competent jurisdiction shall determine by final, non-appealable written order that indemnification of an Indemnified Party in the manner contemplated hereby is prohibited by applicable laws and regulations.

(c) WAFD (and the Surviving Corporation) shall maintain LBC’s existing directors’ and officers’ liability insurance policy (or provide a policy providing comparable coverage and amounts on terms no less favorable to the persons currently covered by LBC’s existing policy, including WAFD’s existing policy if it meets the foregoing standard) covering persons who are currently covered by such insurance for a period of six (6) years after the Effective Time; provided, however, that in no event shall WAFD be obligated to expend, in order to maintain or provide insurance coverage pursuant to this Section 6.10(c), an amount in excess of 300% of the annual premiums paid by LBC as of the date hereof for such insurance (“Maximum Insurance Amount”); provided, further, that if the amount of the annual premiums necessary to maintain or procure such insurance coverage exceeds the Maximum Insurance Amount, WAFD shall obtain what it reasonably determines to be the most advantageous coverage obtainable for an annual premium equal to the Maximum Insurance Amount. WAFD shall provide proof of such coverage to LBC no later than ten (10) Business Days prior to the Effective Time.

(d) The obligations of WAFD and the Surviving Corporation under this Section 6.10 shall not be terminated or modified by such parties in a manner adverse to any Indemnified Party or any other Person entitled to the benefits of this Section 6.10, or to whom this Section 6.10 applies, without the written consent of the effected Indemnified Party or Parties and/or such other Person, as the case may be. If WAFD or any of its successors or assigns shall consolidate with or merge into any other entity and shall not be the continuing or surviving entity of such consolidation or merger or shall transfer all or substantially all of its assets to any other entity, then and in each case, proper provision shall be made so that the successors and assigns of WAFD shall assume the obligations set forth in this Section 6.10.

(e) The provisions of this Section 6.10 are (i) intended to be for the benefit of, and will be enforceable by, each Indemnified Party and his or her heirs and his or her representatives, as set forth in Section 9.07 herein, and (ii) in addition to, and not in substitution for, any other rights to indemnification or contribution that any such Person may have by contract or otherwise.

6.11 Benefit Plans.

(a) As soon as administratively practicable after the Effective Time, WAFD shall take all reasonable action so that employees of LBC and its Subsidiaries who continue to remain employed by WAFD or its Subsidiaries (“Continuing Employees”) shall be entitled to participate in each WAFD Benefit Plan of general applicability to the same extent as similarly-situated employees of WAFD and its Subsidiaries (it being understood that inclusion of the Continuing Employees in the WAFD Benefit Plans may occur at different times with respect to different plans), provided that coverage shall be continued under the corresponding Benefit Plans of LBC and its Subsidiaries until such Continuing Employees are permitted to participate in the WAFD Benefit Plans and provided further, however, that nothing contained herein shall require WAFD or any of its Subsidiaries to make any grants to any former employee of LBC and its Subsidiaries under any discretionary equity compensation plan of WAFD. WAFD shall cause each WAFD Benefit Plan in which Continuing Employees of LBC and its Subsidiaries are eligible to participate to recognize, for purposes of determining eligibility to participate in, the vesting of benefits and for all other purposes (but not for accrual of pension benefits) under the

A-50

##### Table of Contents

WAFD Benefit Plans, the service of such Continuing Employees with LBC and its Subsidiaries to the same extent as such service was credited for such purpose by LBC and its Subsidiaries, provided, however, that such service shall not be recognized to the extent that such recognition would result in a duplication of benefits or to the extent not otherwise permissible under the terms of a WAFD Benefit Plan. Nothing herein shall limit the ability of WAFD to amend or terminate any of the WAFD Benefit Plans or the LBC Benefit Plans in accordance with their terms at any time.

(b) At and following the Effective Time, WAFD shall honor, and the Surviving Corporation shall continue to be obligated to perform, in accordance with their terms, all benefit obligations to, and contractual rights of, current and former employees of LBC and its Subsidiaries and current and former directors of LBC and its Subsidiaries existing as of the Effective Date, as well as all bonus, deferred compensation, supplemental retirement plan, salary continuation, severance, termination, change in control and other existing plans and policies of LBC and its Subsidiaries to the extent that each of the foregoing are Previously Disclosed.

(c) At such time as the Continuing Employees become eligible to participate in a medical, dental, health, life or disability plan of WAFD or its Subsidiaries, WAFD shall cause each such plan to (i) waive any preexisting condition limitations to the extent such conditions are covered under the applicable medical, health or dental plans of WAFD, (ii) provide full credit under medical, health and dental plans for any deductibles, co-payment and out-of-pocket expenses incurred by the Continuing Employees and their beneficiaries during the portion of the calendar year prior to such participation, (iii) waive any waiting period limitation or evidence of insurability requirement which would otherwise be applicable to such employee on or after the Effective Time to the extent such Continuing Employee had satisfied any similar limitation or requirement under a corresponding LBC Benefit Plan prior to the Effective Time, provided, however, that such waiver shall not be required to the extent that such waiver would result in a duplication of benefits or to the extent not otherwise permissible under the terms of a contract insuring benefits under the WAFD Benefit Plans, and (iv) for a period of at least two (2) years, be sponsored by one or more of the entities specified on Schedule 6.11(c).

(d) LBC and WAFD shall cooperate in good faith to determine a mutually agreed communications plan with respect to employment decisions regarding Continuing Employees. By January 31, 2023 (or such other date as mutually agreed among the Parties), WAFD shall identify and deliver offer letters to the Continuing Employees. Those employees of LBC and its Subsidiaries who are not offered employment by WAFD or its Subsidiaries following the Effective Time, who are not a party to an employment agreement or otherwise entitled to an existing severance package and who sign and deliver the termination and release agreement accompanying the severance policy adopted by LBC and set forth on Schedule 6.11(d), within 30 days of the Effective Time, shall be entitled to receive a single lump sum payment of severance in an amount and in accordance with the terms of the severance policy set forth on Schedule 6.11(d). If LBC or any of its Subsidiaries has any other severance pay plan or arrangement, then any amounts paid pursuant to that plan or arrangement shall reduce the amount that the employee will receive under this Section 6.11(d) and in no event shall there be any duplication of severance pay. Nothing contained in this Section 6.11(d) shall be construed or interpreted to limit or modify in any way WAFD’s or its Subsidiaries at will employment policy or provide any third party beneficiary rights to employees of LBC or any of its Subsidiaries. In no event shall severance pay be taken into account in determining the amount of any other benefit (including but not limited to, an individual’s benefit under any retirement plan or policy).

(e) Prior to the Closing, LBC shall have paid into the Luther Burbank Corporation 401(k) Plan (the “LBC Retirement Plan”) all discretionary employer contributions required to be paid to the LBC Retirement Plan pursuant to its terms, including any employer matching contributions, profit sharing contributions or other non-elective contributions. Prior to the Closing, LBC shall (i) adopt written resolutions (or take such other necessary or appropriate action), in form and substance reasonably acceptable to WAFD, to terminate the LBC Retirement Plan in compliance with its terms and requirements of applicable law, effective no later than the Business Day preceding the Closing Date and (ii) provide for full vesting of all non-elective contributions under the LBC Retirement Plan for all participants who currently maintain an account under the LBC Retirement Plan,

A-51

##### Table of Contents

such termination and vesting to be effective no later than the Business Day preceding the Closing Date. LBC shall provide WAFD with evidence of the termination of the LBC Retirement Plan.

(f) Each of LBC and WAFD acknowledges and agrees that all provisions contained within this Section 6.11 with respect to Employees are included for the sole benefit of LBC and nothing contained in this Section 6.11 shall confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Section 6.11. Nothing contained herein (i) shall be construed to establish, amend or modify any benefit plan, program or arrangement or (ii) alter or limit the ability of WAFD to amend, modify or terminate any benefit plan, program or arrangement at any time established, sponsored or maintained by WAFD or any of its Subsidiaries. Each of LBC and WAFD agrees that the terms of this Section 6.11 do not and shall not create any right in any Person to continued employment with LBC, WAFD or any of their respective Subsidiaries or to any compensation or benefit.

Each individual shall serve until the next annual meeting of shareholders of WAFD following the Effective Time at which the class of directors to which such appointee shall be appointed is presented to shareholders for reelection. In the event an appointee is appointed to a class of WAFD directors who will be presented to WAFD’s shareholders for reelection within twenty-four (24) months following the Closing Date, WAFD shall include such individual on the list of nominees for director presented by the WAFD Board and for which the WAFD Board shall solicit proxies at such annual meeting of shareholders of WAFD, to serve for the applicable term for the appointee’s class of directors and until such appointee’s successor shall be duly elected and qualified, provided, that such nomination and solicitation would not violate the fiduciary duties of the WAFD Board.

6.17 Consents. LBC shall, and shall cause its Subsidiaries to, use their commercially reasonable best efforts to obtain all consents, approvals, waivers, non-objections and to deliver any notices required pursuant to the terms of the Material Contracts as a result of the Transaction.

(c) Delay. By WAFD or LBC in the event the Merger is not consummated by November 30, 2023 (the “Outside Date”), except to the extent that the failure of the Merger to be consummated by such date shall be due to (i) the failure of the party seeking to terminate pursuant to this Section 8.01(c) to perform or observe the covenants and agreements of such party set forth in this Agreement or (ii) the failure of any of the Key Shareholders (if LBC is the party seeking to terminate) to perform or observe their respective covenants and agreements under the relevant Key Shareholder Agreement; provided, that the Outside Date may be extended to February 29, 2024 by either WAFD or LBC by written notice to the other party if the Closing shall not have occurred by November 30, 2023, and on such date, the condition set forth in Section 7.01(b) has not been satisfied or waived and each of the other conditions set forth in Article VII has been satisfied or waived (other than those conditions that by their nature are to be satisfied at the Closing; provided, further, that such conditions would have been capable of being satisfied on the Outside Date).

(ii) if this Agreement is terminated by (A) WAFD pursuant to Section 8.01(b), (B) either WAFD or LBC pursuant to Section 8.01(c) and at the time of such termination no vote of the LBC shareholders contemplated by this Agreement at the LBC Meeting shall have occurred, or (C) WAFD pursuant to Section 8.01(e), and in the case of any termination pursuant to clause (A), (B) or (C), an Acquisition Proposal shall have been publicly announced and communicated or made known to the executive officers of LBC or the LBC Board (or any Person shall have publicly announced and communicated or made known an intention, whether or not conditional, to make an Acquisition Proposal, or reiterated a previously expressed plan or intention to make an Acquisition Proposal) at any time after the date of this Agreement and prior to the taking of the vote of the shareholders of LBC contemplated by this Agreement at the LBC Meeting, in the case of clause (C), or the date of termination, in the case of clause (A) or (B), then (1) if within nine (9) months after such termination LBC enters into an agreement with respect to a Control Transaction, which was the subject of such Acquisition Proposal, then LBC shall pay to WAFD an amount equal to $19.63 million on the date of execution of such agreement and upon consummation of such Control Transaction at any time thereafter, LBC shall pay to WAFD the remainder of the Termination Fee on the date of such consummation and (2) if a Control Transaction is consummated otherwise than pursuant to an agreement with LBC within 12 months after such termination, then LBC shall pay to WAFD the Termination Fee (less any amount previously paid by LBC pursuant to clause (1) above) on the date of such consummation of such Control Transaction. As used in this Section 8.02(b), a “Control Transaction” means (i) the acquisition by any Person whether by purchase, merger, consolidation, sale, transfer or otherwise, in one transaction or any series of transactions, of a majority of the voting power of the outstanding securities of LBC or LB Savings or a majority of the assets of LBC or LB Savings, (ii) any issuance of securities resulting in the ownership by any Person of more than 50% of the voting power of LBC or by any Person other than LBC or its Subsidiaries of more than 50% of the voting power of LB Savings or (iii) any merger, consolidation or other business combination transaction involving LBC or any of its Subsidiaries as a result of which the shareholders of LBC cease to own, in the aggregate, at least 50% of the total voting power of the entity surviving or resulting from such transaction.

##### Table of Contents

Any amount that becomes payable pursuant to this Section 8.02(b) shall be paid by wire transfer of immediately available funds to an account designated by WAFD. Under no circumstances shall LBC be obligated to pay the entire Termination Fee on more than one occasion, and the parties hereby acknowledge and agree that in the event the entire Termination Fee becomes payable and is paid by LBC pursuant to this Section 8.02(b), the Termination Fee shall be WAFD’s sole and exclusive remedy under this Agreement.

(c) LBC and WAFD agree that the agreement contained in paragraph (b) above is an integral part of the transactions contemplated by this Agreement, that without such agreement WAFD would not have entered into this Agreement, and that such amounts do not constitute a penalty or liquidated damages in the event of a breach of this Agreement by LBC. If LBC fails to pay WAFD the amounts due under Section 8.02(b) above within the time periods specified in Section 8.02(b), LBC shall pay the costs and expenses (including reasonable legal fees and expenses) incurred by WAFD in connection with any action, including the filing of any lawsuit, taken to collect payment of such amounts, provided WAFD prevails on the merits, together with interest on the amount of any such unpaid amounts at the prime lending rate prevailing during such period as published in The Wall Street Journal, calculated on a daily basis from the date such amounts were required to be paid until the date of actual payment.

ARTICLE IX

MISCELLANEOUS

9.01 Survival. No representations, warranties, agreements and covenants contained in this Agreement shall survive the Effective Time (other than agreements or covenants contained herein that by their express terms are to be performed after the Effective Time) or the termination of this Agreement if this Agreement is terminated prior to the Effective Time (other than Sections 6.06(e), 8.02 and this Article IX, which shall survive any such termination). Notwithstanding anything in the foregoing to the contrary, no representations, warranties, agreements and covenants contained in this Agreement shall be deemed to be terminated or extinguished so as to deprive a party hereto or any of its affiliates of any defense at law or in equity which otherwise would be available against the claims of any Person, including without limitation any shareholder or former shareholder.

9.02 Waiver; Amendment. Prior to the Effective Time, any provision of this Agreement may be (i) waived, by the party benefited by the provision or (ii) amended or modified at any time, by an agreement in writing among the parties hereto executed in the same manner as this Agreement, except that after the approval of the principal terms of this Agreement by the LBC shareholders, no amendment shall be made which by law requires further approval by the shareholders of LBC without obtaining such approval. For purposes of clarification, an amendment of any date in Section 8.01(c) shall not require further approval by any shareholders and if such amendment were deemed by law to require further approval by the shareholders of LBC, the approval of the principal terms of this Agreement by the LBC shareholders will be deemed to have granted LBC the authority to amend such dates without such further approval.

9.03 Counterparts. This Agreement may be executed in one or more counterparts, all of which shall be deemed to constitute one and the same original agreement.

9.04 Governing Law. This Agreement shall be governed by, and interpreted in accordance with, the laws of the State of Washington applicable to contracts made and to be performed entirely within such State.

9.05 Expenses. Each party hereto will bear all expenses incurred by it in connection with this Agreement and the Transaction, including fees and expenses of its own financial consultants, accountants and counsel; provided, that nothing contained herein shall limit either party’s rights to recover any liabilities or damages arising out of the other party’s fraud or willful breach of any provision of this Agreement.

9.07 Entire Understanding; Limited Third Party Beneficiaries. This Agreement (including the agreements, documents and instruments referred to herein) represent the entire understanding of the parties hereto with reference to the Transaction and supersede any and all other oral or written agreements heretofore made with respect to the subject matter hereof. Except for the Indemnified Parties’ right to enforce WAFD’s obligation under Section 6.10, which are expressly intended to be for the irrevocable benefit of, and shall be enforceable by, each Indemnified Party and his or her heirs and representatives, nothing in this Agreement, expressed or implied, is intended to confer upon any Person, other than the parties hereto and their respective successors and permitted assigns, any rights, remedies, obligations or liabilities under or by reason of this Agreement.

9.08 Severability. Except to the extent that application of this Section 9.08 would have a Material Adverse Effect on LBC or WAFD, any term or provision of this Agreement which is invalid or unenforceable in any

A-58

##### Table of Contents

jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement or affecting the validity or enforceability of any of the terms or provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only so broad as is enforceable. In all such cases, the parties shall use their reasonable best efforts to substitute a valid, legal and enforceable provision which, insofar as practicable, implements the original purposes and intents of this Agreement.

9.09 Enforcement of the Agreement. The parties hereto agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached. Except as provided in Section 8.02(b), it is accordingly agreed that the parties shall be entitled to an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions hereof in any court of the United States or any state having jurisdiction, this being in addition to any other remedy to which they are entitled at law or in equity. In the event attorneys’ fees or other costs are incurred to secure performance of any of the obligations herein provided for, or to establish damages for the breach thereof, or to obtain any other appropriate relief, whether by way of prosecution or defense, the prevailing party shall be entitled to recover reasonable attorneys’ fees and costs incurred therein.

9.10 Interpretation. When a reference is made in this Agreement to Sections, Exhibits or Schedules, such reference shall be to a Section of, or Exhibit or Schedule to, this Agreement unless otherwise indicated. The table of contents and headings contained in this Agreement are for reference purposes only and are not part of this Agreement. Whenever the words “include,” “includes” or “including” are used in this Agreement, they shall be deemed to be followed by the words “without limitation.” Whenever the words “as of the date hereof” are used in this Agreement, they shall be deemed to mean the day and year first above written. The term “made available” means any document or other information that was (i) provided by one party or its representatives to the other party and its representatives, (ii) included in the virtual data room of a party or (iii) filed by a party with the SEC and publicly available on EDGAR, in each case not less than four (4) Business Days prior to the date hereof.

9.11 Assignment. No party may assign either this Agreement or any of its rights, interests or obligations hereunder without the prior written approval of the other parties. Subject to the preceding sentence, this Agreement shall be binding upon and shall inure to the benefit of the parties hereto and their respective successors and permitted assigns.

9.12 Alternative Structure. Notwithstanding any provision of this Agreement to the contrary, WAFD may at any time modify the structure of the acquisition of LBC set forth herein, provided that (i) the Merger Consideration to be paid to the holders of LBC Common Stock is not thereby changed in kind or reduced in amount as a result of such modification, (ii) such modifications will not adversely affect the United States federal income Tax treatment to LBC’s shareholders in connection with the Merger (including, but not limited to, any such change that would result in the Merger failing to qualify as a reorganization described in Section 368(a) of the Code), and (iii) such modification will not jeopardize receipt of any required approvals of Governmental Authorities or delay consummation of the Transactions contemplated by this Agreement.

9.13 Confidential Supervisory Information. Notwithstanding any other provision of this Agreement, no disclosure, representation or warranty shall be made (or other action taken) pursuant to this Agreement that would involve the disclosure of confidential supervisory information (including confidential supervisory information as defined in 12 C.F.R. § 261.2(c) and as identified in 12 C.F.R. § 309.5(g)(8)) of a Governmental Authority by any party to this Agreement to the extent prohibited by applicable law. For purposes of clarity, a representation relating to receipt of regulatory approvals on a timely basis shall not be given, or continue to be given, to the extent the reason for it no longer continuing to be accurate involves such confidential supervisory information. To the extent legally permissible, appropriate substitute disclosures or actions shall be made or taken under circumstances in which the limitations of the preceding sentences apply.

ANNEX A

SHAREHOLDER AGREEMENT

SHAREHOLDER AGREEMENT (this “Agreement”), dated as of November 13, 2022, among , a shareholder (“Shareholder”) of Luther Burbank Corporation, a California corporation (“LBC”), Washington Federal, Inc., a Washington corporation (“WAFD”), and, solely for purposes of the last sentence of Section 8, LBC. All terms used herein and not defined herein shall have the meanings assigned thereto in the Merger Agreement (defined below).

WHEREAS, LBC and WAFD are entering into an Agreement and Plan of Reorganization, dated as of the date hereof (the “Merger Agreement”), pursuant to which LBC will merge with and into WAFD on the terms and conditions set forth therein (the “Merger”) and, in connection therewith, outstanding shares of LBC Common Stock will be converted into shares of WAFD Common Stock in the manner set forth therein; and

WHEREAS, Shareholder owns the shares of LBC Common Stock identified on Exhibit I hereto (such shares, together with all shares of LBC Common Stock subsequently acquired by Shareholder during the term of this Agreement, being referred to as the “Shares”); and

WHEREAS, in order to induce WAFD to enter into the Merger Agreement, Shareholder, solely in such Shareholder’s capacity as a shareholder of LBC and not in any other capacity, has agreed to enter into and perform this Agreement.

NOW, THEREFORE, for good and valuable consideration, the receipt, sufficiency and adequacy of which are hereby acknowledged, the parties hereto agree as follows:

1. Agreement to Vote Shares. Shareholder agrees while this Agreement is in effect, that at any meeting of the shareholders of LBC, or in connection with any written consent of the shareholders of LBC, Shareholder shall:

(a) appear at each such meeting or otherwise cause the Shares to be counted as present thereat for purposes of calculating a quorum; and

(b) vote (or cause to be voted), in person or by proxy, or deliver a written consent (or cause a consent to be delivered) covering, all the Shares (whether acquired heretofore or hereafter) that are beneficially owned by Shareholder or as to which Shareholder has, directly or indirectly, the right to vote or direct the voting, (x) in favor of adoption and approval of the Merger, the Merger Agreement and the transactions contemplated thereby; (y) against any action or agreement that to the knowledge of the Shareholder would reasonably be expected to result in a breach of any covenant, representation or warranty or any other obligation or agreement of LBC contained in the Merger Agreement or of Shareholder contained in this Agreement; and (z) against any Acquisition Proposal or any other action, agreement or transaction that is intended, or to the knowledge of the Shareholder would reasonably be expected, to materially impede, interfere or be inconsistent with, delay, postpone, discourage or materially and adversely affect consummation of the Merger or the performance by Shareholder of his, her or its obligations under this Agreement; provided, that if there is any amendment, waiver or modification to the Merger Agreement that is effected after the date hereof that (x) reduces or has the effect of reducing the Exchange Ratio, (y) changes the form of all or any portion of the Merger Consideration and/or (z) imposes any material condition to the receipt of Merger Consideration (any such amendment, waiver or modification, a “Material Merger Agreement Change”), this Section 1 shall be inapplicable.

2. Transfer of Shares.

(a) Prohibition on Transfers of Shares; Other Actions. Shareholder hereby agrees that while this Agreement is in effect, Shareholder shall not, (i) sell, transfer, pledge, encumber, distribute by gift or donation, or otherwise dispose of any of the Shares (or any securities convertible into or exercisable or

A-1

##### Table of Contents

exchangeable for Shares) or any interest therein, whether by actual disposition, physical settlement or effective economic disposition through hedging transactions, derivative instruments or other means, (ii) enter into any agreement, arrangement or understanding with any Person, or take any other action, that violates or conflicts with or could reasonably be expected to violate or conflict with Shareholder’s representations, warranties, covenants and obligations under this Agreement, or (iii) take any other action that could reasonably be expected to impair or otherwise adversely affect, in any material respect, Shareholder’s power, authority and ability to comply with and perform his, her or its covenants and obligations under this Agreement; provided, however, that once the Shares have been voted at the LBC Meeting as provided for in Section 1(b)(x) hereof, and provided that at least a majority of all of the issued and outstanding shares of LBC Common Stock have been irrevocably voted in favor of the Merger, the Merger Agreement and the transactions contemplated thereby at the LBC Meeting as provided for in Section 1(b)(x) hereof, then the prohibitions provided for in this Section 2 shall no longer apply to Shareholder.

(b) Transfer of Voting Rights. Shareholder hereby agrees that Shareholder shall not deposit any Shares in a voting trust, grant any proxy or enter into any voting agreement or similar agreement or arrangement with respect to any of the Shares.

3. Limitations on Sales.1 Shareholder hereby agrees that, during the thirty-six (36) month period immediately following the Closing Date, Shareholder shall not sell, transfer, pledge, hypothecate, encumber, distribute by gift or donation, or otherwise dispose of any of the Shares in excess of the amounts set forth below without WAFD’s prior written consent:

Relevant Period |  | Maximum Number of Shares
Months 1 through 12 |  | [●]
Months 13 through 24 |  | [●]
Months 25 through 36 |  | [●]

4. Representations and Warranties of Shareholder. Shareholder represents and warrants to and agrees with WAFD as follows:

(a) Capacity. Shareholder has all requisite capacity and authority to enter into and perform his, her or its obligations under this Agreement.

(b) Binding Agreement. This Agreement has been duly executed and delivered by Shareholder and constitutes the valid and legally binding obligation of Shareholder, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors’ rights and to general equity principles.

(c) Non-Contravention. The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations hereunder and the consummation by Shareholder of the transactions contemplated hereby will not, violate or conflict with, or constitute a default under, any agreement, instrument, contract or other obligation or any order, arbitration award, judgment or decree to which Shareholder is a party or by which Shareholder is bound, or any statute, rule or regulation to which Shareholder is subject or, in the event that Shareholder is a corporation, partnership, trust or other entity, any charter, bylaw or other organizational document of Shareholder.

(d) Ownership. Shareholder’s Shares are, and, except as otherwise provided for in Section 2(a) hereof, through the term of this Agreement will be, owned beneficially and of record solely by Shareholder, except as otherwise disclosed on Exhibit I hereto. Shareholder has title to the Shares, free and clear of any lien, pledge, mortgage, security interest or other encumbrance, except as otherwise disclosed on Exhibit I hereto. As of the date hereof, the Shares identified on Exhibit I hereto constitute all of the shares of LBC Common Stock owned beneficially or of record by Shareholder. Shareholder has and, except as otherwise

1 | This Section 3 will be included only in the Shareholder Agreement entered into by LBC’s Board Chair and shall provide for the sale of one-third of the Shares during each of the 12-month periods indicated.

##### Table of Contents

provided for in Section 2(a) above, will have at all times during the term of this Agreement (i) sole voting power and sole power to issue instructions with respect to the matters set forth in Section 1 hereof, (ii) sole power of disposition and (iii) sole power to agree to all of the matters set forth in this Agreement, in each case with respect to all of the Shares owned by Shareholder on the date of this Agreement and all of the Shares hereafter acquired by Shareholder and owned beneficially or of record by him, her or it during the term of this Agreement. For purposes of this Agreement, the term “beneficial ownership” shall be interpreted in accordance with Rule 13d-3 under the Exchange Act, provided that a Person shall be deemed to beneficially own any securities which may be acquired by such Person pursuant to any agreement, arrangement or understanding or upon the exercise of conversion rights, exchange rights, warrants or options, or otherwise (irrespective of whether the right to acquire such securities is exercisable immediately or only after the passage of time, including the passage of time within 60 days, the satisfaction of any conditions, the occurrence of any event or any combination of the foregoing).

(e) Consents and Approvals. The execution and delivery of this Agreement by Shareholder does not, and the performance by Shareholder of his, her or its obligations under this Agreement and the consummation by him, her or it of the transactions contemplated hereby will not, require Shareholder to obtain any consent, approval, authorization or permit of, or to make any filing with or notification to, any Governmental Authority.

(f) Absence of Litigation. There is no suit, action, investigation or proceeding pending or, to the knowledge of Shareholder, threatened against or affecting Shareholder or any of his, her or its affiliates before or by any Governmental Authority that could reasonably be expected to materially impair the ability of Shareholder to perform his, her or its obligations hereunder or to consummate the transactions contemplated hereby on a timely basis.

5. No Solicitation. Shareholder hereby agrees that during the term of this Agreement he, she or it shall not, and shall not permit any investment banker, financial advisor, attorney, accountant or other representative retained by him, her or it to, directly or indirectly, (a) take any of the actions specified in clauses (i)-(vi) of Section 6.07(a) of the Merger Agreement, (b) agree to release, or release, any Person from any obligation under any existing standstill agreement or arrangement relating to LBC, or (c) participate in, directly or indirectly, a “solicitation” of “proxies” (as such terms are used in the rules of the SEC) or powers of attorney or similar rights to vote, or seek to advise or influence any Person with respect to the voting of, any shares of LBC Common Stock in connection with any vote or other action on any matter of a type described in Section 1(b), other than to recommend that shareholders of LBC vote in favor of the adoption and approval of the Merger Agreement and the Merger and as otherwise expressly permitted by this Agreement. Shareholder agrees immediately to cease and cause to be terminated any activities, discussions or negotiations conducted before the date of this Agreement with any Persons other than WAFD with respect to any possible Acquisition Proposal and will take all necessary steps to inform any investment banker, financial advisor, attorney, accountant or other representative retained by him, her or it of the obligations undertaken by Shareholder pursuant to this Section 5. Nothing contained in this Section 5 shall prevent a Shareholder who is an officer or a member of the LBC Board from discharging his or her fiduciary duties solely in his or her capacity as such an officer or director.

6. Notice of Acquisitions; Proposals Regarding Prohibited Transactions. Shareholder hereby agrees to notify WAFD promptly (and in any event within two (2) Business Days) in writing of the number of any additional shares of LBC Common Stock or other securities of LBC of which Shareholder acquires beneficial or record ownership on or after the date hereof. Shareholder will comply with the provisions of Section 6.07(b) of the Merger Agreement as if he, she or it were LBC.

7. Specific Performance and Remedies. Shareholder acknowledges that it will be impossible to measure in money the damage to WAFD if Shareholder fails to comply with the obligations imposed by this Agreement and that, in the event of any such failure, WAFD will not have an adequate remedy at law. Accordingly, Shareholder agrees that injunctive relief or other equitable remedy, in addition to remedies at law or in damages, is the appropriate remedy for any such failure and will not oppose the granting of such relief on the basis that WAFD

APPENDIX B

OPINION OF KEEFE, BRUYETTE & WOODS, INC.

November 13, 2022

The Board of Directors

Washington Federal, Inc.

425 Pike Street

Seattle, WA 98101

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 Washington Federal, Inc. (“Washington Federal”) of the Exchange Ratio (as defined below) in the proposed merger (the “Merger”) of Luther Burbank Corporation (“Luther Burbank”) with and into Washington Federal, pursuant to the Agreement and Plan of Reorganization (the “Agreement”) to be entered into by and between Washington Federal and Luther Burbank. Pursuant to the Agreement and subject to the terms, conditions and limitations set forth therein, at the Effective Time (as defined in the Agreement), automatically by virtue of the Merger and without any action on the part of a holder of shares of the common stock, no par value per share, of Luther Burbank (“Luther Burbank Common Stock”), each share of Luther Burbank Common Stock issued and outstanding immediately prior to the Effective Time will be converted into the right to receive 0.3353 of a share of the common stock, $1.00 par value per share, of Washington Federal (“Washington Federal Common Stock”). The ratio of 0.3353 of a share of Washington Federal Common Stock for one share of Luther Burbank 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 Washington Federal and Luther Burbank will cause Washington Federal Bank, dba WAFD Bank, a wholly-owned subsidiary of Washington Federal (“WAFD Bank”), and Luther Burbank Savings, a wholly-owned subsidiary of Luther Burbank (“LB Savings”), respectively, to enter into a separate bank merger agreement pursuant to which LB Savings will merge with and into WAFD Bank (such transaction, the “Bank Merger”) promptly following consummation of the Merger.

KBW has acted as financial advisor to Washington Federal 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 an existing sales and trading relationship between (i) Washington Federal and each of KBW and a KBW broker-dealer affiliate and (ii) Luther Burbank and a KBW broker-dealer affiliate), may from time to time purchase securities from, and sell securities to, Washington Federal and Luther Burbank. 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 Washington Federal or Luther Burbank for our and their own respective accounts and for the accounts of our and their respective customers and clients. We have acted exclusively for the board of directors of Washington Federal (the “Board”) in rendering this opinion and will receive a fee from Washington Federal for our services. A portion of our fee is payable upon the rendering of this opinion, and a significant

portion is contingent upon the successful completion of the Merger. In addition, Washington Federal 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 and financial advisory services to Washington Federal and received compensation for such services. KBW acted as co-manager for Washington Federal’s February 2021 offering of preferred stock. In the past two years, KBW has not provided investment banking or financial advisory services to Luther Burbank. We may in the future provide investment banking and financial advisory services to Washington Federal or Luther Burbank 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 Washington Federal and Luther Burbank and bearing upon the Merger, including among other things, the following: (i) a draft of the Agreement dated November 11, 2022 (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 September 30, 2021 of Washington Federal; (iii) the unaudited quarterly financial statements and the Quarterly Reports on Form 10-Q for the fiscal quarters ended December 31, 2021, March 31, 2022 and June 30, 2022 of Washington Federal; (iv) certain unaudited financial results for the fiscal year and the fiscal quarter ended September 30, 2022 of Washington Federal (contained in the Current Report on Form 8-K filed by Washington Federal with the Securities and Exchange Commission on October 14, 2022); (v) the audited financial statements and the Annual Reports on Form 10-K for the three fiscal years ended December 31, 2021 of Luther Burbank; (vi) the unaudited quarterly financial statements and the Quarterly Reports on Form 10-Q for the fiscal quarters ended March 31, 2022, June 30, 2022 and September 30, 2022 of Luther Burbank; (vii) certain regulatory filings of Washington Federal and Luther Burbank and their respective subsidiaries, including the quarterly reports on Form FR Y-9C and quarterly call reports filed with respect to each quarter during the three year period ended December 31, 2021 as well as the quarters ended March 31, 2022, June 30, 2022 and September 30, 2022; (viii) certain other interim reports and other communications of Washington Federal and Luther Burbank to their respective shareholders; and (ix) other financial information concerning the respective businesses and operations of Washington Federal and Luther Burbank furnished to us by Washington Federal and Luther Burbank or which we were otherwise directed to use for purposes of our analysis. 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 Washington Federal and Luther Burbank; (ii) the assets and liabilities of Washington Federal and Luther Burbank; (iii) the nature and terms of certain other merger transactions and business combinations in the banking industry; (iv) a comparison of certain financial and stock market information of Washington Federal and Luther Burbank with similar information for certain other companies, the securities of which are publicly traded; (v) publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management), as well as assumed long-term growth rates for Luther Burbank provided to us by Washington Federal management, all of which information was discussed with us by Washington Federal management and used and relied upon by us at the direction of such management and with the consent of the Board; (vi) publicly available consensus “street estimates” of Washington Federal, as well as assumed long-term growth rates for Washington Federal provided to us by Washington Federal management, all of which information was discussed with us by Washington Federal 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 Washington Federal (including, without limitation, the cost savings and related expenses expected to result or be derived from the Merger) that were prepared by Washington Federal management, provided to and discussed with us by such management, and used and relied upon by us at the direction of such 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 that were held by the managements of Washington Federal and Luther Burbank 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 provided to or discussed with 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 Washington Federal management as to the reasonableness and achievability of the publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management), the publicly available consensus “street estimates” of Washington Federal, the assumed long-term growth rates for Luther Burbank and Washington Federal, and the estimates regarding certain pro forma financial effects of the Merger on Washington Federal (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 (as so adjusted in the case of the publicly available consensus “street estimates” of Luther Burbank) has been reasonably prepared and represents, or in the case of the publicly available consensus “street estimates” of Washington Federal referred to above that such estimates are consistent with, the best currently available estimates and judgments of Washington Federal 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. As you are aware, the publicly available consensus “street estimates” of Luther Burbank (as adjusted by Washington Federal management), as well as the assumed long-term growth rates for Luther Burbank provided to us by Washington Federal management, all of which we were directed by such management to use, reflect differences from the forecasts and projections that were prepared by Luther Burbank and provided to Washington Federal. Accordingly, with the consent of Washington Federal, in rendering our opinion, our reliance upon Washington Federal management as to the reasonableness and achievability of such publicly available consensus “street estimates” of Luther Burbank (as so adjusted) and such assumed long-term growth rates for Luther Burbank includes reliance upon the judgments, estimates and assessments of Washington Federal management with respect to such differences.

It is understood that the portion of the foregoing financial information of Washington Federal and Luther Burbank that was provided to us was not prepared with the expectation of public disclosure and that all of the foregoing financial information, including the publicly available consensus “street estimates” of Luther Burbank and Washington Federal, is based on numerous variables and assumptions that are inherently uncertain (including, without limitation, factors related to general economic and competitive conditions and, in particular, the widespread disruption, extraordinary uncertainty and unusual volatility arising from global tensions and political unrest, economic uncertainty, inflation, and the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions) and, accordingly, actual results could vary significantly from those set forth in such information. We have assumed, based on discussions with the management of Washington Federal and with the consent of the Board, that all such information provides a reasonable basis upon which we can form our opinion and we express no view as to any such information or the assumptions or bases therefor. Among other things, such information has assumed that the ongoing COVID-19 pandemic could have an adverse impact on Washington Federal and Luther Burbank. 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 have assumed that there have been no material changes in the assets, liabilities, financial condition, results of operations, business or prospects of either Washington Federal or Luther Burbank 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 each of Washington Federal and Luther Burbank 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 Washington Federal or Luther Burbank, 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 Washington Federal or Luther Burbank 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. Such estimates are inherently subject to uncertainty and should not be taken as our view of the actual value of any companies or assets.

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 Luther Burbank Common Stock; (ii) that the representations and warranties of each party in the Agreement and in all related documents 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 transactions 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 transactions, 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 Washington Federal, Luther Burbank 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 Washington Federal that Washington Federal 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 Washington Federal, Luther Burbank, the Merger and any related transaction (including the Bank Merger), 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 Washington Federal. 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 the Bank Merger), including without limitation, the form or structure of the Merger or any such related transaction, any consequences of the Merger or any related transaction to Washington Federal, its shareholders, creditors or otherwise, 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, any such related

transaction, 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. There is currently significant volatility in the stock and other financial markets arising from global tensions and political unrest, economic uncertainty, inflation, and the COVID-19 pandemic, including the effect of evolving governmental interventions and non-interventions. 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 Washington Federal 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 Washington Federal or the Board, (iii) the fairness of the amount or nature of any compensation to any of Washington Federal’s officers, directors or employees, or any class of such persons, relative to any compensation to the holders of Washington Federal Common Stock or relative to the Exchange Ratio, (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 Washington Federal, Luther Burbank or any other party to any transaction contemplated by the Agreement, (v) the actual value of Washington Federal Common Stock to be issued in connection with the Merger, (vi) the prices, trading range or volume at which Washington Federal Common Stock or Luther Burbank Common Stock will trade following the public announcement of the Merger or the prices, trading range or volume at which Washington Federal 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 Washington Federal, Luther Burbank, any of their respective shareholders, or relating to or arising out of or as a consequence of the Merger or any other 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 Washington Federal 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’, affiliates’ or other 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 Washington Federal.

Very truly yours,

APPENDIX C

OPINION OF PIPER SANDLER & CO.

November 13, 2022

Board of Directors

Luther Burbank Corporation

520 Third Street

Fourth Floor

Santa Rosa, CA 95401

Ladies and Gentlemen:

Luther Burbank Corporation (“LBC”) and Washington Federal, Inc. (“WAFD”) are proposing to enter into an Agreement and Plan of Reorganization (the “Agreement”) pursuant to which, at the Effective Time, LBC shall merge with and into WAFD with WAFD as the surviving corporation (the “Merger”). As set forth in the Agreement, at the Effective Time, each share of LBC Common Stock issued and outstanding immediately prior to the Effective Time, except for certain shares of LBC Common Stock as specified in the Agreement, shall be converted into the right to receive 0.3353 (the “Exchange Ratio”) of a share of WAFD Common Stock. Capitalized terms used herein without definition shall have the meanings ascribed thereto in the Agreement. You have requested our opinion as to the fairness, from a financial point of view, of the Exchange Ratio to the holders of LBC Common Stock.

Piper Sandler & Co. (“Piper Sandler”, “we” or “our”), as part of its investment banking business, is regularly engaged in the valuation of financial institutions and their securities in connection with mergers and acquisitions and other corporate transactions. In connection with this opinion, we have reviewed and considered, among other things: (i) a draft of the Agreement, dated November 10, 2022; (ii) certain publicly available financial statements and other historical financial information of LBC that we deemed relevant; (iii) certain publicly available financial statements and other historical financial information of WAFD that we deemed relevant; (iv) certain internal net income projections for LBC for the years ending December 31, 2022 through December 31, 2024, estimated net income for LBC for the twelve months ending September 30, 2025 assuming annualized net income for the quarter ended December 31, 2024 with an estimated annual net income growth rate for the years ending September 30, 2026 and September 30, 2027 and estimated dividends per share for the years ending December 31, 2023 through September 30, 2027, as provided by the senior management of LBC; (v) publicly available mean analyst net income estimates for WAFD for the fiscal years ending September 30, 2023 and September 30, 2024, as well as a long-term annual earnings per share growth rate for the fiscal years ending September 30, 2025 through September 30, 2027 and estimated dividends per share for WAFD for the fiscal years ending September 30, 2023 through September 30, 2027, as provided by the senior management of WAFD; (vi) the pro forma financial impact of the Merger on WAFD based on estimated net income for LBC for the fiscal years ending September 30, 2023 and September 30, 2024 with an estimated annual net income growth rate for LBC for the fiscal years ending September 30, 2025 through September 30, 2027, as well as certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, and certain adjustments for current expected credit losses (CECL) accounting standards, as provided by the senior management of WAFD; (vii) the publicly reported historical price and trading activity for LBC Common Stock and WAFD Common Stock, including a comparison of certain stock trading information for LBC Common Stock, WAFD Common Stock and certain stock indices, as well as similar publicly available information for certain other companies, the securities of which are publicly traded; (viii) a comparison of certain financial and market information for LBC and WAFD with similar financial institutions for which information is publicly

C-1

##### Table of Contents

available; (ix) the financial terms of certain recent business combinations in the bank and thrift industry (on a nationwide basis), to the extent publicly available; (x) the current market environment generally and the banking environment in particular; and (xi) such other information, financial studies, analyses and investigations and financial, economic and market criteria as we considered relevant. We also discussed with certain members of the senior management of LBC and its representatives the business, financial condition, results of operations and prospects of LBC and held similar discussions with certain members of the senior management of WAFD and its representatives regarding the business, financial condition, results of operations and prospects of WAFD.

In performing our review, we have relied upon the accuracy and completeness of all of the financial and other information that was available to us from public sources, that was provided to us by LBC, WAFD or their respective representatives, or that was otherwise reviewed by us and we have assumed such accuracy and completeness for purposes of rendering this opinion without any independent verification or investigation. We have further relied on the assurances of the respective senior managements of LBC and WAFD that they are not aware of any facts or circumstances that would make any of such information inaccurate or misleading in any respect material to our analyses. We have not been asked to undertake, and have not undertaken, an independent verification of any such information and we do not assume any responsibility or liability for the accuracy or completeness thereof. We did not make an independent evaluation or perform an appraisal of the specific assets, the collateral securing assets or the liabilities (contingent or otherwise) of LBC or WAFD, nor were we furnished with any such evaluations or appraisals. We render no opinion on, or evaluation of, the collectability of any assets or the future performance of any loans of LBC or WAFD. We did not make an independent evaluation of the adequacy of the allowance for loan losses of LBC or WAFD, or the combined entity after the Merger, and we have not reviewed any individual credit files relating to LBC or WAFD. We have assumed, with your consent, that the respective allowances for loan losses for both LBC and WAFD are adequate to cover such losses and will be adequate on a pro forma basis for the combined entity.

In preparing its analyses, Piper Sandler used certain internal net income projections for LBC for the years ending December 31, 2022 through December 31, 2024, estimated net income for LBC for the twelve months ending September 30, 2025 assuming annualized net income for the quarter ended December 31, 2024 with an estimated annual net income growth rate for the years ending September 30, 2026 and September 30, 2027 and estimated dividends per share for the years ending December 31, 2023 through September 30, 2027, as provided by the senior management of LBC. In addition, Piper Sandler used publicly available mean analyst net income estimates for WAFD for the fiscal years ending September 30, 2023 and September 30, 2024, as well as a long-term annual earnings per share growth rate for the fiscal years ending September 30, 2025 through September 30, 2027 and estimated dividends per share for WAFD for the fiscal years ending September 30, 2023 through September 30, 2027, as provided by the senior management of WAFD. Piper Sandler also received and used in its pro forma analyses estimated net income for LBC for the fiscal years ending September 30, 2023 and September 30, 2024 with an estimated annual net income growth rate for LBC for the fiscal years ending September 30, 2025 through September 30, 2027, as well as certain assumptions relating to transaction expenses, purchase accounting adjustments and cost savings, and certain adjustments for CECL accounting standards, as provided by the senior management of WAFD. With respect to the foregoing information, the respective senior managements of LBC and WAFD confirmed to us that such information reflected (or in the case of the publicly available analyst estimates referred to above, were consistent with) the best currently available projections, estimates and judgements of senior management as to the future financial performance of LBC and WAFD, respectively, and we assumed that the financial results reflected in such information would be achieved. We express no opinion as to such projections, estimates or judgements, or the assumptions on which they are based. We have also assumed that there has been no material change in LBC’s or WAFD’s assets, financial condition, results of operations, business or prospects since the date of the most recent financial statements made available to us. We have assumed in all respects material to our analyses that LBC and WAFD will remain as going concerns for all periods relevant to our analyses.

We have also assumed, with your consent, that (i) each of the parties to the Agreement will comply in all material respects with all material terms and conditions of the Agreement and all related agreements required to effect the Merger, that all of the representations and warranties contained in such agreements are true and correct

C-2

##### Table of Contents

in all material respects, that each of the parties to such agreements will perform in all material respects all of the covenants and other obligations required to be performed by such party under such agreements and that the conditions precedent in such agreements are not and will not be waived, (ii) in the course of obtaining the necessary regulatory or third party approvals, consents and releases with respect to the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on LBC, WAFD, the Merger or any related transactions, and (iii) the Merger and any related transactions will be consummated in accordance with the terms of the Agreement without any waiver, modification or amendment of any material term, condition or agreement thereof and in compliance with all applicable laws and other requirements. Finally, with your consent, we have relied upon the advice that LBC has received from its legal, accounting and tax advisors as to all legal, accounting and tax matters relating to the Merger and the other transactions contemplated by the Agreement. We express no opinion as to any such matters.

Our opinion is necessarily based on financial, regulatory, 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 could materially affect this opinion. We have not undertaken to update, revise, reaffirm or withdraw this opinion or otherwise comment upon events occurring after the date hereof. We express no opinion as to the trading value of LBC Common Stock or WAFD Common Stock at any time or what the value of WAFD Common Stock will be once it is actually received by the holders of LBC Common Stock.

We have acted as LBC’s financial advisor in connection with the Merger and will receive an advisory fee for our services, which fee is contingent upon consummation of the Merger. We will also receive a fee for rendering this opinion, which opinion fee will be credited in full towards the advisory fee which will become due and payable to Piper Sandler upon consummation of the Merger. LBC has also agreed to indemnify us against certain claims and liabilities arising out of our engagement and to reimburse us for certain of our out-of-pocket expenses incurred in connection with our engagement. Piper Sandler has not provided any other investment banking services to LBC in the two years preceding the date hereof, nor did Piper Sandler provide any investment banking services to WAFD in the two years preceding the date hereof. In the ordinary course of our business as a broker-dealer, we may purchase securities from and sell securities to LBC and WAFD. We may also actively trade the equity and debt securities of LBC and WAFD for our own account and for the accounts of our customers.

Our opinion is directed to the Board of Directors of LBC in connection with its consideration of the Agreement and the Merger and does not constitute a recommendation to any shareholder of LBC as to how any such shareholder should vote at any meeting of shareholders called to consider and vote upon the approval of the Agreement and the Merger. Our opinion is directed only as to the fairness, from a financial point of view, of the Exchange Ratio to the holders of LBC Common Stock and does not address the underlying business decision of LBC to engage in the Merger, the form or structure of the Merger or any other transactions contemplated in the Agreement, the relative merits of the Merger as compared to any other alternative transactions or business strategies that might exist for LBC or the effect of any other transaction in which LBC might engage. We also do not express any opinion as to the fairness of the amount or nature of the compensation to be received in the Merger by any LBC officer, director or employee, or class of such persons, if any, relative to the amount of compensation to be received by any other shareholder. This opinion has been approved by Piper Sandler’s fairness opinion committee. This opinion may not be reproduced without Piper Sandler’s prior written consent; provided, however, Piper Sandler will provide its consent for the opinion to be included in any regulatory filings, including the joint Proxy Statement, to be filed with the SEC and mailed to shareholders in connection with the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair to the holders of LBC Common Stock from a financial point of view.

Very truly yours,

PART II

INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. | Indemnification of Directors and Officers.

Section 23B.08.320 of the WBCA provides that the personal liability of directors and officers to a corporation imposed by Section 23B.08.310 of the WBCA may be eliminated by the articles of incorporation of the corporation, except in the case of acts or omissions involving certain types of conduct. Article 9 of the Registrant’s Restated Articles of Incorporation provides that directors of the Registrant shall not be personally liable to the Registrant or its shareholders for monetary damages for conduct as a director to the fullest extent permitted by the WBCA. Thus, a director or officer of the Registrant is not personally liable to the Registrant or its shareholders for monetary damages for conduct as a director or officer, except for liability (1) for acts or omissions finally adjudged to be intentional misconduct or a knowing violation of law, (2) for conduct finally adjudged to be in violation of Section 23B.08.310 of the WBCA, or (3) for any transaction for which it was finally adjudged that the director or officer personally received a benefit in money, property or services to which such person was not legally entitled. If Washington law is amended to authorize corporate action that further eliminates or limits the liability of directors or officers, then the liability of the Registrant’s directors and officers will be eliminated or limited to the fullest extent permitted by Washington law, as so amended.

Section 23B.08.560 of the WBCA provides that if authorized by (1) the articles of incorporation, (2) a bylaw adopted or ratified by the shareholders, or (3) a resolution adopted or ratified, before or after the event, by the shareholders, a corporation will have the power to indemnify directors made party to a proceeding, or to obligate itself to advance or reimburse expenses incurred in a proceeding, without regard to the limitations on indemnification contained in Sections 23B.08.510 through 23B.08.550 of the WBCA, provided that no such indemnity may indemnify any director (a) for acts or omissions that involve intentional misconduct or a knowing violation of law, (b) for conduct violating Section 23B.08.310 of the WBCA, or (c) for any transaction from which the indemnitee will personally receive a benefit in money, property or services to which such person is not legally entitled. In Article VI of its Bylaws and Article 8 of its Articles of Incorporation, the Registrant has elected, subject to certain exceptions, to indemnify and hold harmless directors and officers of the Registrant who, while serving as directors or officers of the Registrant, were serving at the request of the Registrant as a director, officer, partner, trustee, employee or agent of another foreign or domestic enterprise against liabilities incurred because of such service, to the extent permitted by law. Such indemnification does not include indemnification for (1) for acts or omissions finally adjudged to be intentional misconduct or a knowing violation of law; (2) for conduct finally adjudged to be in violation of Section 23B.08.310 of the WBCA; (3) for any transaction for which it was finally adjudged that the director or officer personally received a benefit in money, property or services to which such person was not legally entitled, or (4) if the Registrant is otherwise prohibited by applicable law.

Also, pursuant to Article VI of the Registrant’s Bylaws, the Registrant will, to the extent permitted by applicable law, pay reasonable expenses incurred by a director or officer in defending any matter of the type described above for which indemnification is available in advance of the matter’s final disposition, so long as (i) the indemnified person undertakes to repay all amounts so advanced if it is ultimately determined by final judicial decision from which there is no further right to appeal that such indemnified person is not entitled to be indemnified under Article VI of the Registrant’s Bylaws, and (ii) the indemnified person provides to the Registrant a written affirmation of the indemnified person’s good faith belief that they have met the standard of conduct described in Section 23B.08.510 of the WBCA. Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers or persons controlling the Registrant pursuant to the provisions described above, the Registrant has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

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, as amended (the “Securities Act”); (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 SEC 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, 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 purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934, as amended (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, as amended) 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.

(5) 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 Registrant 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.

(6) That every prospectus (i) that is filed pursuant to paragraph (5) above, or (ii) that purports to meet the requirements of Section 10(a)(3) of the Securities Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to this registration statement and will not be used until such amendment has become effective, and that for the purpose of determining liabilities under the Securities Act, 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.

(7) To respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form S-4 Registration Statement, within one 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 the registration statement through the date of responding to the request.

II-3

##### Table of Contents

(8) 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.

(9) Insofar as indemnification for liabilities arising under the Securities Act 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 SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for 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 the 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 and will be governed by the final adjudication of such issue.
