N otes to Consolidated Financial Statements (unaudited)

​

​

Note 1 — Basis of Presentation

​

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America, otherwise referred to as GAAP, for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and disclosures required for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Certain prior period information has been reclassified to conform to the current period presentation, and these reclassifications had no impact on net income or equity as previously reported. Operating results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results that may be expected for the year ending December 31, 2023.

​

The consolidated balance sheet at December 31, 2022 has been derived from the audited financial statements at that date but does not include all of the information and disclosures required by GAAP for complete financial statements.

Note 2 — Summary of Significant Accounting Policies

​

The information contained in the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the Securities and Exchange Commission (the “SEC”) on February 24, 2023, should be referenced when reading these unaudited consolidated financial statements. Unless otherwise mentioned or unless the context requires otherwise, references herein to “SouthState,” the “Company” “we,” “us,” “our” or similar references mean SouthState Corporation and its consolidated subsidiaries. References to the “Bank” or “SouthState Bank” means SouthState Corporation’s wholly owned subsidiary, South State Bank, National Association, a national banking association.

​

Loans

​

Loans that management has originated and has the intent and ability to hold for the foreseeable future or until maturity or pay off generally are reported at their unpaid principal balances, less unearned income and net of any deferred loan fees and costs, including unamortized fair value discount or premium. Unearned income on installment loans is recognized as income over the terms of the loans by methods that generally approximate the interest method. Interest on other loans is calculated by using the simple interest method on daily balances of the principal amount outstanding. If the loan is prepaid, the remaining unamortized fees and costs are charged or credited to interest income. Amortization ceases for non-accrual loans.

​

We place non-acquired loans and acquired loans on nonaccrual once reasonable doubt exists about the collectability of all principal and interest due. Generally, this occurs when principal or interest is 90 days or more past due, unless the loan is well secured and in the process of collection and excludes factored receivables. For factored receivables, which are commercial trade credits rather than promissory notes, the Company’s practice, in most cases, is to charge-off unpaid recourse receivables when they become 90 days past due from the invoice due date and the non-recourse receivables when they become 120 days past due from the statement due date. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful.

​

A loan is evaluated individually for loss when it is on nonaccrual and has a net book balance over $1 million. Large pools of homogeneous loans are collectively evaluated for loss and reserved at the pool level. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as nonaccrual, provided that management expects to collect all amounts due, including interest accrued at the contractual interest rate for the period of delay.

Allowance for Credit Losses (“ACL”) – Investment Securities

​

Management monitors the held to maturity portfolio to determine whether a valuation account should be recorded. Management evaluates impairment where there has been a decline in fair value below the amortized cost basis of a security to determine whether there is a credit loss associated with the decline in fair value at least quarterly, and more frequently when economic or market concerns warrant such evaluation. The Company’s methodology on how ACL is calculated is disclosed in Note 1 — Summary of Significant Accounting Policies, under the “ACL – Investment Securities” section, of our Annual Report on Form 10-K for the year ended December 31, 2022. As of September 30, 2023 and December 31, 2022, the Company had $2.5 billion and $2.7 billion, respectively, of held to maturity securities and no related valuation account.

The Company follows its nonaccrual policy by reversing interest income in the income statement when the Company determines the interest for held to maturity securities is uncollectible. Therefore, management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the investment securities and does not record an allowance for credit losses on accrued interest receivable. As of September 30, 2023 and December 31, 2022, the accrued interest receivables for all investment securities recorded in Other Assets were $25.6 million and $28.2 million, respectively.

ACL – Loans and Certain Off-Balance-Sheet Credit Exposures

The ACL for loans held for investment reflects management’s estimate of credit losses that will result from the inability of our borrowers to make required loan payments. The Company makes adjustments to the ACL by recording a provision for or recovery of credit losses through earnings. Loans charged off are recorded as reductions to the ACL on the balance sheet and subsequent recoveries of loan charge-offs are recorded as increases to the ACL when they are received.

​

Management uses systematic methodologies to determine its ACL for loans held for investment and certain off-balance-sheet credit exposures. The ACL is a valuation account that is deducted from the amortized cost basis to present the net amount expected to be collected on the loan portfolio. Management considers the effects of past events, current conditions, and reasonable and supportable forecasts on the collectability of the loan portfolio. The Company’s estimate of its ACL involves a high degree of judgment; therefore, management’s process for determining expected credit losses may result in a range of expected credit losses. The Company’s ACL recorded in the balance sheet reflects management’s best estimate within the range of expected credit losses. The Company recognizes in net income the amount needed to adjust the ACL for management’s current estimate of expected credit losses.

​

The Company’s ACL is calculated using collectively evaluated and individually evaluated loans. The Company’s methodology on how ACL is calculated is disclosed in Note 1 — Summary of Significant Accounting Policies, under the “ACL – Loans” section, of our Annual Report on Form 10-K for the year ended December 31, 2022.

​

As of January 1, 2023, the Company adopted and applied prospectively ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures, that requires the elimination of designation of loans as TDRs. Management measures expected credit losses over the contractual term of a loan. When determining the contractual term, the Company considers expected prepayments but is precluded from considering expected extensions, renewals, or modifications. Longstanding TDR accounting rules were replaced as of January 1, 2023 with ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (See Note 3 — Recent Accounting and Regulatory Pronouncements). In accordance with the adoption of ASU 2022-02, any loans modified to a borrower experiencing financial difficulty are reviewed by the Bank to determine if an interest rate reduction, a term extension, an other-than-insignificant payment delay, a principal forgiveness, or any combination of these has occurred.

​

Table of Contents

Effective January 1, 2023, the ACL includes expected losses from modifications of receivables to borrowers experiencing financial difficulty. Losses on modifications of non-accrual loans over $1 million to borrowers experiencing financial difficulty are estimated on an individual basis. Because the effect of the remainder of modifications made to borrowers experiencing financial difficulty is already incorporated into the measurement methodologies used to estimate the allowance, they are accounted for as pooled loans. The effects of reasonably expected TDRs are no longer considered in the measurement of expected credit losses. Prior to the adoption of ASU No. 2022-02, when determining the contractual term, the Company considered expected prepayments but was precluded from considering expected extensions, renewals, or modifications, unless the Company reasonably expected it would execute a TDR with a borrower. In the event of a reasonably expected TDR, the Company factored the reasonably-expected TDR into the expected credit losses estimate. For consumer loans, the point at which a TDR was reasonably expected was when the Company approved the borrower’s application for a modification (i.e., the borrower qualifies for the TDR) or when the Credit Administration department approved loan concessions on substandard loans. For commercial loans, the point at which a TDR was reasonably expected was when the Company approved the loan for modification or when the Credit Administration department approved loan concessions on substandard loans. The Company used a discounted cash flow methodology for a TDR to calculate the effect of the concession provided to the borrower within the ACL.

​

For purchased credit-deteriorated, otherwise referred to herein as PCD, assets are defined as acquired individual financial assets (or acquired groups of financial assets with similar risk characteristics) that, as of the date of acquisition, have experienced a more-than-insignificant deterioration in credit quality since origination, as determined by the Company’s assessment. The Company records acquired PCD loans by adding the expected credit losses (i.e., allowance for credit losses) to the purchase price of the financial assets rather than recording through the provision for credit losses in the income statement. The expected credit loss, as of the acquisition day, of a PCD loan is added to the allowance for credit losses. The non-credit discount or premium is the difference between the unpaid principal balance and the amortized cost basis as of the acquisition date. Subsequent to the acquisition date, the change in the ACL on PCD loans is recognized through the Provision for Credit Losses in the Consolidated Statements of Net Income. The non-credit discount or premium is accreted or amortized, respectively, into interest income over the remaining life of the PCD loan on a level-yield basis.

​

The Company follows its nonaccrual policy by reversing contractual interest income in the income statement when the Company places a loan on nonaccrual status. Therefore, management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the portfolio and does not record an allowance for credit losses on accrued interest receivable. As of September 30, 2023 and December 31, 2022, the accrued interest receivables for loans recorded in Other Assets were $123.1 million and $105.4 million, respectively.

​

The Company has a variety of assets that have a component that qualifies as an off-balance sheet exposure. These primarily include undrawn portions of revolving lines of credit and standby letters of credit. The expected losses associated with these exposures within the unfunded portion of the expected credit loss are recorded as a liability on the balance sheet. Management has determined that a majority of the Company’s off-balance sheet credit exposures are not unconditionally cancellable. Management completes funding studies based on historical data to estimate the percentage of unfunded loan commitments that will ultimately be funded to calculate the reserve for unfunded commitments. Management applies this funding rate, along with the loss factor rate determined for each pooled loan segment, to unfunded loan commitments, excluding unconditionally cancellable exposures and letters of credit, to arrive at the reserve for unfunded loan commitments. As of September 30, 2023 and December 31, 2022, the liabilities recorded for expected credit losses on unfunded commitments were $62.3 million and $67.2 million, respectively. The current adjustment to the ACL for unfunded commitments is recognized through the Provision for Credit Losses in the Consolidated Statements of Net Income.

Certain amounts previously reported have been reclassified to conform to the current quarter’s presentation. Such reclassifications had no effect on net income and shareholders’ equity.

During 2022, the Company determined the variation margin payments for its interest rate swaps centrally cleared through London Clearing House (“LCH”) and Chicago Mercantile Exchange (“CME”) meet the legal characteristics of daily settlements of the derivatives (settle-to-market) rather than collateral (collateralize-to-market). As a result, the variation margin payment and the related derivative instruments centrally cleared through LCH and CME are considered a single unit of account for accounting and financial reporting purposes. Depending on the net position, the fair value is reported in Derivative Assets or Derivative Liabilities on the Consolidated Balance Sheets, as opposed to interest-earning deposits (restricted cash) within Cash and Cash Equivalents or interest-bearing deposits within Total Deposits. In addition, the expense or income attributable to the variation margin payments for the centrally cleared swaps is reported in Noninterest Income, specifically within Correspondent and Capital Markets Income, as opposed to Interest Income or Interest Expense. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument. As a result of the correction from collateralize-to-market accounting treatment previously applied by the Company to settle-to-market accounting treatment, the prior periods presented herein have been corrected, for what management has concluded to be an immaterial correction.

​

The table below discloses the net change (increase or (decrease)) included in all the Consolidated Statements of Net Income line items in this Form 10-Q, as a result of the change in accounting treatment. There was no impact to Net Income or Shareholders’ Equity as previously reported.

Note 3 — Recent Accounting and Regulatory Pronouncements

​

Accounting Standards Adopted

In March 2022, FASB issued ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. The amendments in this ASU eliminate the long-standing accounting guidance for Troubled Debt Restructurings (“TDRs”) by creditors in Subtopic 310-40, Receivables – Troubled Debt Restructurings by Creditors, as it is no longer meaningful due to the introduction of Topic 326, which requires an entity to consider lifetime expected credit losses on loans when establishing an allowance for credit losses. Thus, most losses that would have been realized for a TDR under Subtopic 310-40 are now captured by the accounting required under Topic 326. The amendments in this ASU also require that an entity disclose current-period gross write offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments – Credit Losses Measured at Amortized Cost. The Company adopted ASU No. 2022-02 effective January 1, 2023. We elected to apply a prospective transition method, which applies only to modifications occurring after the adoption date. For loans meeting the Bank’s materiality criteria, which includes loans in excess of $250,000, an assessment of whether a borrower is experiencing financial difficulty is made on the date of the modification. On the transition date, the former TDR loans as of December 31, 2022 were designated as individually evaluated loans on January 1, 2023 and retained the allowance for credit losses allocated to these loans at the adoption date as the credit risk of these did not change. Aside from the changes to the disclosures required by ASU No. 2022-02, the ASU did not have a material impact on our consolidated financial statements.

In March 2020, FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848 – Facilitation of the Effects of Reference Rate Reform on Financial Reporting and subsequently expanded the scope of ASU No. 2020-04 with the issuance of ASU No. 2021-01 and extended the sunset date to December 31, 2024 with ASU No. 2022-06. This update provides companies with optional guidance to ease the potential accounting burden associated with transitioning away from reference rates that will be discontinued. The amendments in this update provide optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criteria are met. The main provisions for contract modifications include optional relief by allowing the modification as a continuation of the existing contract without additional analysis and other optional expedients regarding embedded features. The amendments in this update were effective for all entities as of March 12, 2020 and may be applied through December 31, 2022. In January 2021, the FASB issued ASU 2021-01 which clarified that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2022-06 extended the effective date through December 31, 2024. The amendments are effective as of March 12, 2020 through December 31, 2024 and can be adopted at the instrument level on an ongoing basis. Management adopted these optional expedients beginning April 1, 2023 to coincide with the transition and modification of our LIBOR-exposed instruments. Most of the loan modifications met the requirements of these practical expedients, as most were subject to the Adjustable Interest Rate (LIBOR) Act which permits a replacement index with a spread adjustment. These modifications did not have a material impact on the consolidated financial statements.

​

Issued But Not Yet Adopted Accounting Standards

​

In March 2023, FASB issued ASU No. 2023-02, Investments—Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. The Proportional Amortization method was introduced by ASU No. 2014-01, but limited this amortization method to investments in low-income housing tax credit structures. The amendments in ASU 2023-02 will allow entities the option to elect whether they account for tax equity investments using the proportional amortization method if certain conditions are met, regardless of the program from which the income tax credits are received. The election would be on a program-by-program basis. The ASU would also require disclosures to be transparent about an entity’s investments that generate income tax credits and other income tax benefits. The amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years with early adoption permitted. The Company maintains investments in low-income housing tax structures and will evaluate whether it will change its current accounting treatment for low-income housing tax credits. The Company does not anticipate this ASU will have a material impact on its financial statements.

Note 4 — Mergers and Acquisitions

​

Atlantic Capital Bancshares, Inc. (“Atlantic Capital” or “ACBI”)

​

On March 1, 2022, the Company acquired all of the outstanding common stock of Atlantic Capital in a stock transaction. Upon the terms and subject to the conditions set forth therein, Atlantic Capital merged with and into the Company, with the Company continuing as the surviving corporation in the merger. Immediately following the merger, Atlantic Capital’s wholly owned banking subsidiary, Atlantic Capital Bank, N.A. (“ACB”) merged with and into the Bank, which continues as the surviving bank. Shareholders of Atlantic Capital received 0.36 shares of the Company’s common stock for each share of Atlantic Capital common stock they owned. In total, the purchase price for Atlantic Capital was $657.8 million.

​

In the acquisition, the Company acquired $2.4 billion of loans, including PPP loans, at fair value, net of $54.3 million, or 2.24%, estimated discount to the outstanding principal balance, representing 10.0% of the Company’s total loans at December 31, 2021. Of the total loans acquired, management identified $137.9 million that had more than insignificantly deteriorated since origination and were thus determined to be PCD loans.

​

During the nine months ended September 30, 2023, the Company incurred approximately $2.4 million of acquisition costs related to this transaction. The Company did no t incur acquisition cost related to this transaction during the three months ended September 30, 2023. During the three and nine months ended September 30, 2022, the Company incurred approximately $7.1 million and $15.0 million, respectively, of acquisition costs related to this transaction. These acquisition costs are reported in Merger and Branch Consolidation Related Expenses on the Company’s Consolidated Statements of Net Income.

Table of Contents

The acquisition was accounted for under the acquisition method of accounting in accordance with ASC Topic 805. The Company recognized goodwill on this acquisition of $342.0 million. The goodwill was calculated based on the fair values of the assets acquired and liabilities assumed as of the acquisition date.

​

Our other investment securities consist of non-marketable equity securities that have no readily determinable market value. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value. As of September 30, 2023, we determined that there was no impairment on other investment securities.

The amortized cost and fair value of debt securities at September 30, 2023, by contractual maturity are detailed below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without prepayment penalties.

​

The Company’s evaluation methodology for securities impairment is disclosed in Note 3 — Securities, under “Investment Securities” section, of our Annual Report on Form 10-K for the year ended December 31, 2022. All debt securities in an unrealized loss position as of September 30, 2023 continue to perform as scheduled and we do not believe there is a credit loss or a provision for credit losses is necessary. We do not currently intend to sell the securities within the portfolio and it is not more-likely-than-not that we will be required to sell the debt securities. See Note 2 — Summary of Significant Accounting Policies for further discussion.

​

Management continues to monitor all of our securities with a high degree of scrutiny. There can be no assurance that we will not conclude in future periods that conditions existing at that time indicate some or all of its securities may be sold or would require a charge to earnings as a provision for credit losses in such periods.

Non-credit discount at acquisition | ​ |  | (5,943) | ​
Carrying value or book value of acquired loans at acquisition | ​ | $ | 118,173 | ​

​

As part of the ongoing monitoring of the credit quality of our loan portfolio, management tracks certain credit quality indicators, including trends related to (i) the level of classified loans, (ii) net charge-offs, (iii) non-performing loans (see details below), and (iv) the general economic conditions of the markets that we serve.

​

The Company utilizes a risk grading matrix to assign a risk grade to each commercial loan. Classified loans are assessed at a minimum every six months. A description of the general characteristics of the risk grades is as follows:

​

| ● | Pass—These loans range from minimal credit risk to average, however, still acceptable credit risk.

| ● | Special mention—A special mention loan has potential weaknesses that deserve Management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or the institution’s credit position at some future date.

| ● | Substandard—A substandard loan is inadequately protected by the current sound worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified must have a well-defined weakness, or weaknesses, that may jeopardize the liquidation of the debt. A substandard loan is characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected.

| ● | Doubtful—A doubtful loan has all of the weaknesses inherent in one classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of the currently existing facts, conditions and values, highly questionable and improbable.

Construction and land development loans in the following table are on commercial and speculative real estate. Consumer owner occupied loans are collateralized by 1-4 family owner occupied property with a business intent.

The Bank designates individually evaluated loans on non-accrual with a net book balance exceeding the designated threshold as collateral dependent loans. Collateral dependent loans are loans for which the repayment is expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty. These loans do not share common risk characteristics and are not included within the collectively evaluated loans for determining ACL. Under ASC 326-20-35-6, the Bank has adopted the collateral maintenance practical expedient to measure the ACL based on the fair value of collateral. The ACL is calculated on an individual loan basis based on the shortfall between the fair value of the loan's collateral, which is adjusted for selling costs, and amortized cost. If the fair value of the collateral exceeds the amortized cost, no allowance is required. The Bank’s threshold for individually evaluated loans is $1.0 million. The significant changes above in collateral percentage are due to appraisal value updates or changes in the number of loans within the asset class and collateral type. Overall collateral dependent loans increased $57.7 million during the nine months ended September 30, 2023.

​

Loans on nonaccrual status at the date of modification are initially classified as nonaccrual. Loans on accruing status at the date of modification are initially classified as accruing if the note is reasonably assured of repayment and performance is expected in accordance with its modified terms. Such loans may be designated as nonaccrual loans subsequent to the modification date if reasonable doubt exists as to the collection of interest or principal under the modification agreement. Nonaccrual loans are returned to accruing status when there is economic substance to the modification, there is documented credit evaluation of the borrower’s financial condition, the remaining balance is reasonably assured of repayment in accordance with its modified terms, and the borrower has demonstrated sustained repayment performance in accordance with the modified terms for a reasonable period of time (generally a minimum of six months). Refer to See Note 2 — Summary of Significant Accounting Policies for further detailed discussion on loan modified to a borrower experiencing financial difficulty and the losses from modifications of receivables to borrowers experiencing financial difficulty.

​

The following tables present loans designated as modifications made to borrowers experiencing financial difficulty during the nine months ended September 30, 2023 resulting from the adoption of ASU 2022-02, segregated by type of modification and asset class, and indicating the financial effect of the modifications. There were no modifications of this nature for the three months ended September 30, 2023. The amortized cost balance for the modified loans presented below exclude accrued interest receivable of approximately $54,000 as of September 30, 2023.

The Bank on occasion will enter into modification agreements which extend the maturity payoff on a loan or reduce the interest rate, for borrowers willing to continue to pay, to minimize losses for the Bank. At September 30, 2023, the Company had $3.3 million remaining in commitments to lend additional funds on loans to borrowers experiencing financial difficulty and modified during the current reporting period.

Note 9 — Leases

​

As of September 30, 2023 and December 31, 2022, we had operating right-of-use (“ROU”) assets of $103.1 million and $108.0 million, respectively, and operating lease liabilities of $111.0 million and $115.6 million, respectively. We maintain operating leases on land and buildings for some of our operating centers, branch facilities and ATM locations. Most leases include one or more options to renew, with renewal terms extending up to 21 years. The exercise of renewal options is based on the sole judgment of management and what they consider to be reasonably certain given the environment today. Factors in determining whether an option is reasonably certain of exercise include, but are not limited to, the value of leasehold improvements, the value of renewal rates compared to market rates, and the presence of factors that would cause a significant economic penalty to us if the option is not exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet and instead are recognized in lease expense on a straight-line basis over the lease term.

Terms and conditions are similar to those real estate operating leases described above. Lease classifications from the acquired institutions were retained. As of September 30, 2023, we did not maintain any leases with related parties, and determined that the number and dollar amount of our equipment leases was immaterial. As of September 30, 2023, we had no additional operating leases that have not yet commenced.

Note 11 — Retirement Plans

​

The Company sponsors an employees’ savings plan under the provisions of the Internal Revenue Code Section 401(k). Electing employees are eligible to participate in the employees’ savings plan after attaining age 21. Plan participants elect to contribute portions of their annual base compensation as a before tax contribution. Employer contributions may be made from current or accumulated net profits. Participants may elect to contribute 1% to 50% of annual base compensation as a before tax contribution. Employees participating in the plan received a 100% match of their 401(k) plan contribution from the Company, up to 4% of their salary. We expensed $4.0 million and $12.7 million, respectively, for the three and nine months ended September 30, 2023 and $3.9 million and $12.0 million, respectively, for the three and nine months ended September 30, 2022 related to the Company’s savings plan.

​

Employees can enter the savings plan on or after the first day of each month. The employee may enter into a salary deferral agreement at any time to select an alternative deferral amount or to elect not to defer in the plan. If the employee does not elect an investment allocation, the plan administrator will select a retirement-based portfolio according to the employee’s number of years until normal retirement age. The plan’s investment valuations are generally provided on a daily basis.

Note 12 — Earnings Per Share

​

Basic earnings per share is calculated by dividing net income by the weighted-average shares of common stock outstanding during each period, excluding non-vested restricted shares. Our diluted earnings per share is based on the weighted-average shares of common stock outstanding during each period plus the maximum dilutive effect of common stock issuable upon exercise of stock options or vesting of restricted stock units. Stock options and unvested restricted stock units are considered common stock equivalents and are only included in the calculation of diluted earnings per common share when their effect is dilutive.

​

The following table sets forth the computation of basic and diluted earnings per common share:

Note 13 — Share-Based Compensation

​

Our 2004, 2012, 2019 and 2020 share-based compensation plans are long-term retention plans intended to attract, retain, and provide incentives for key employees and non-employee directors in the form of incentive and non-qualified stock options, restricted stock, and restricted stock units (“RSUs”). Our 2020 plan was adopted by our shareholders at our annual meeting on October 29, 2020. The Company also assumed the obligations of ACBI under various equity incentive plans pursuant to the acquisition of ACBI on March 1, 2022 and the obligations of CenterState under various equity incentive plans pursuant to the merger with CenterState on June 7, 2020.

​

Stock Options

​

With the exception of non-qualified stock options granted to directors under the 2004 and 2012 plans, which in some cases may be exercised at any time prior to expiration and in some other cases may be exercised at intervals less than a year following the grant date, incentive stock options granted under our 2004, 2012, 2019 and 2020 plans may not be exercised in whole or in part within a year following the date of the grant, as these incentive stock options become exercisable in 25% increments pro ratably over the four-year period following the grant date. The options are granted at an exercise price at least equal to the fair value of the common stock at the date of grant and expire ten years from the date of grant. No options were granted under the 2004, 2012 or 2019 plans after January 26, 2012, February 1, 2019, and October 29, 2020, respectively, and the plans are closed other than for any options still unexercised and outstanding. The 2020 plan is the only plan from which new share-based compensation grants may be issued. It is the Company’s policy to grant options out of the 2,072,245 shares registered under the 2020 plan.

Activity in the Company’s stock option plans is summarized in the following table.

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

Exercisable at September 30, 2023 | ​ | 133,690 | ​ | ​ | 69.91 | ​ | 2.67 | ​ | $ | 1,019 | ​

​

The fair value of options is estimated at the date of grant using the Black-Scholes option pricing model and expensed over the options’ vesting periods. There have been no stock options issued during the first nine months of 2023. Because all outstanding stock options had vested as of December 31, 2022, there was no unrecognized compensation cost related to nonvested stock option grants under the plans or fair value of shares vested during the nine months ended September 30, 2023. The intrinsic value of stock option shares exercised for the nine months ended September 30, 2023 was $573,000.

​

Restricted Stock

​

From time-to-time, we grant shares of restricted stock to key employees. These awards help align the interests of these employees with the interests of our shareholders by providing economic value directly related to increases in the value of our stock. The value of the stock awarded is established as the fair market value of the stock at the time of the grant. We recognize expenses equal to the total value of such awards, ratably over the vesting period of the stock grants. Restricted stock grants to employees generally vest ratably over a two to four-year vesting period.

​

​

Table of Contents

All restricted stock agreements are conditioned upon continued employment. Termination of employment prior to a vesting date, as described below, would terminate any interest in non-vested shares. Prior to vesting of the shares, as long as employed by the Company, the employees will have the right to vote such shares and to receive dividends paid with respect to such shares. All restricted shares will fully vest in the event of change in control of the Company or upon the death of the recipient.

​

Nonvested restricted stock for 2023 is summarized in the following table.

​

As of September 30, 2023, there was $858,000 of total unrecognized compensation cost related to nonvested restricted stock granted under the plans. This cost is expected to be recognized over a weighted-average period of 1.01 years as of September 30, 2023. The total fair value of shares vested during the nine months ended September 30, 2023 was $2.4 million.

Restricted Stock Units (“RSUs”)

​

From time-to-time, we also grant performance RSUs and time-vested RSUs to key employees, and time-vested RSUs to non-employee directors. These awards help align the interests of these employees with the interests of our shareholders by providing economic value directly related to our performance. Some performance RSU grants contain a three-year performance period while others contain a one to two-year performance period and a time-vested requirement (generally two to four years from the grant date). The performance-based awards for our long-term incentive plans are dependent on the achievement of tangible book value growth and return on average tangible common equity relative to the Company’s peer group during each three-year performance period. Grants to non-employee directors typically vest within a 12-month period. We communicate threshold, target, and maximum performance RSU awards and performance targets to the applicable key employees at the beginning of a performance period. Due to the merger with CenterState on June 7, 2020, all legacy and assumed performance-based restricted stock units converted to a time-vesting requirement. With respect to some long-term incentive awards, dividend equivalents are accrued at the same rate as cash dividends paid for each share of the Company’s common stock during the performance or time-vested period, and subsequently paid when the shares are issued on the vesting or settlement date. The value of the RSUs awarded is established as the fair market value of the stock at the time of the grant. We recognize expense on a straight-line basis typically over the performance or time-vesting periods based upon the probable performance target, as applicable, that will be met.

Outstanding RSUs at target for the nine months ended September 30, 2023 is summarized in the following table.

​

The nonvested shares of 946,954 at September 30, 2023 includes 147,955 shares that have fully vested but are subject to a two-year holding period, which commenced at the end of their respective vesting period. These vested shares will be released and issued into shares of common stock at the end of their respective two-year holding period, the last of which will end by March 31, 2025. If maximum performance is achieved pursuant to the 2021, 2022 and 2023 Long Term Incentive performance-based RSU grants, an additional 148,756 shares in total may be issued by the Company at the end of the three-year performance periods.

The total fair value of RSUs vested and released during the nine months ended September 30, 2023 was $26.6 million.

Note 14 — Commitments and Contingent Liabilities

​

In the normal course of business, we make various commitments and incur certain contingent liabilities, which are not reflected in the accompanying financial statements. The commitments and contingent liabilities include guarantees, commitments to extend credit, and standby letters of credit. At September 30, 2023, commitments to extend credit and standby letters of credit totaled $10.6 billion. As of September 30, 2023, the liability recorded for expected credit losses on unfunded commitments, excluding unconditionally cancellable exposures and letters of credit, was $62.3 million and recorded on the Balance Sheet. See Note 2 — Summary of Significant Accounting Policies for discussion of liability recorded for expected credit losses on unfunded commitments.

​

We have been named as defendant in various legal actions, arising from its normal business activities, in which damages in various amounts are claimed. We are also exposed to litigation risk related to the prior business activities of banks acquired through whole bank acquisitions. Although the amount of any ultimate liability with respect to such matters cannot be determined, in the opinion of management, as of September 30, 2023, any such liability is not expected to have a material effect on our consolidated financial statements.

In May 2023, the Federal Deposit Insurance Corporation (“FDIC”) approved a notice of proposed rulemaking to implement a special assessment, in connection with the systemic risk determination announced in March 2023, to recover the cost associated with protecting uninsured depositors following the recent bank failures. The FDIC is proposing to collect the special assessment at the base annual rate of approximately 12.5 basis points of the Company’s uninsured deposits reported as of December 31, 2022, adjusted to exclude the first $5 billion, over eight quarterly assessment periods, beginning after the first quarter 2024. We expect the FDIC will enact a special deposit insurance assessment in the second half of 2023 that will significantly increase our FDIC deposit insurance costs. The total cost and timing is subject to change prior to any final rule depending on any adjustments to the loss estimate, mergers or failures, or amendments to reported estimates of uninsured deposits.

Note 15 — Fair Value

​

GAAP defines fair value and establishes a framework for measuring and disclosing fair value. Fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions.

​

The Company uses fair value measurements to record fair value adjustments to certain assets and liabilities and to determine fair value disclosures. Available for sale and trading securities, derivative contracts, mortgage loans held for sale, SBA servicing rights, and mortgage servicing rights (“MSRs”) are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record at fair value other assets on a nonrecurring basis, such as impaired loans, OREO, bank properties held for sale, and certain other assets. These nonrecurring fair value adjustments typically involve application of lower of cost or market accounting or write-downs of individual assets.

​

FASB ASC Topic 820 establishes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value as follows:

​

Level 1 | Observable inputs such as quoted prices in active markets;
Level 2 | Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
Level 3 | Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

​

A description of valuation methodologies used for assets recorded at fair value is disclosed in Note 25 — Fair Value of our Annual Report on Form 10-K for the year ended December 31, 2022.

Fair Value Option

The Company has elected the fair value option for mortgage loans held for sale primarily to ease the operational burden required to maintain hedge accounting for these loans.

The following table summarizes the difference between the fair value and the unpaid principal balance of mortgage loans held for sale and the changes in fair value of these loans.

Changes in Level 1, 2 and 3 Fair Value Measurements

​

When a determination is made to classify a financial instrument within Level 3 of the valuation hierarchy, the determination is based upon the significance of the unobservable factors to the overall fair value measurement. However, since Level 3 financial instruments typically include, in addition to the unobservable or Level 3 components, observable components (that is, components that are actively quoted and can be validated to external sources), the gains and losses below include changes in fair value due in part to observable factors that are part of the valuation methodology.

​

There were no changes in hierarchy classifications of Level 3 assets or liabilities for the nine months ended September 30, 2023. A reconciliation of the beginning and ending balances of Level 3 assets and liabilities recorded at fair value on a recurring basis for the nine months ended September 30, 2023 is as follows:

​

​ | ​ | ​ | ​ | ​
(Dollars in thousands) |  | MSRs |
Fair value, January 1, 2023 | ​ | $ | 86,610 | ​
Servicing assets that resulted from transfers of financial assets | ​ |  | 6,752 | ​

Changes in fair value due to decay | ​ |  | (6,336) | ​
Fair value, September 30, 2023 | ​ | $ | 89,476 | ​

​

In 2022, the Company elected to prospectively apply fair value accounting to the Company’s SBA servicing asset, which is considered a Level 3 asset. A reconciliation of the beginning and ending balances of the SBA servicing asset recorded at fair value on a recurring basis for the period ending September 30, 2023 is as follows:

​

​ | ​ | ​ | ​ | ​
(Dollars in thousands) |  | SBA Servicing Asset |
Fair value, January 1, 2023 | ​ | $ | 6,068 | ​
Servicing assets that resulted from transfers of financial assets | ​ | ​ | 1,103 | ​
Changes in fair value due to decay | ​ | ​ | (1,951) | ​
Changes in fair value due to valuation inputs or assumptions | ​ | ​ | 434 | ​
Fair value, September 30, 2023 | ​ | $ | 5,654 | ​

​

There were no unrealized losses included in accumulated other comprehensive income related to Level 3 financial assets and liabilities at September 30, 2023.

Fair Value of Financial Instruments

​

We used the following methods and assumptions in estimating our fair value disclosures for financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those models are significantly affected by the assumptions used, including the discount rates and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instrument. The use of different methodologies may have a material effect on the estimated fair value amounts. The fair value estimates presented herein are based on pertinent information available to management as of September 30, 2023 and December 31, 2022. Such amounts have not been revalued for purposes of these consolidated financial statements since those dates and, therefore, current estimates of fair value may differ significantly from the amounts presented herein.

​

Methods and assumptions used to estimate the fair value of each class of financial instruments are disclosed in Note 25 — Fair Value of our Annual Report on Form 10-K for the year ended December 31, 2022.

Cash Flow Hedge of Interest Rate Risk

The Company is exposed to interest rate risk in the course of its business operations and manages a portion of this risk through the use of derivative financial instruments, in the form of interest rate swaps. We account for interest rate swaps that are classified as cash flow hedges on the balance sheet at fair value. We had no cash flow hedges as of September 30, 2023 and December 31, 2022. For more information regarding the fair value of our derivative financial instruments, see Note 15 — Fair Value to these financial statements.

The Company did not maintain any cash flow hedges on the balance sheet throughout the nine months ended September 30, 2023 and year ended December 31, 2022 (See Note 16—Accumulated Other Comprehensive Income (Loss) for activity in accumulated comprehensive income (loss) and the amounts reclassified into earnings). With the Company not maintaining any cash flow hedges at September 30, 2023 and December 31, 2022, there was no collateral pledged.

Balance Sheet Fair Value Hedge

​

As of September 30, 2023 and December 31, 2022, the Company maintained loan swaps, with an aggregate notional amount of $9.5 million and $12.3 million, respectively, accounted for as fair value hedges. This derivative protects us from interest rate risk caused by changes in the SOFR curve in relation to a certain designated fixed rate loan. The derivative converts the fixed rate loan to a floating rate. Settlement occurs in any given period where there is a difference in the stated fixed rate and variable rate and the difference is recorded in net interest income. The fair value of this hedge is recorded in either other assets or in other liabilities depending on the position of the hedge with the offset recorded in loans.

Non-designated Hedges of Interest Rate Risk

​

Customer Swap

​

The Company maintains interest rate swap contracts with loan customers of respondent bank customers of the Correspondent Banking Division, in addition to loan customers of the Bank, that are classified as non-designated hedges and are not speculative in nature. These agreements are designed to convert customer’s variable rate loans with the Company and respondent bank customers to fixed rate. These interest rate swaps are executed with loan customers to facilitate a respective risk management strategy and allow the customer to pay a fixed rate of interest to the Company. These interest rate swaps are simultaneously hedged by executing offsetting interest rate swaps with unrelated market counterparties to minimize the net risk exposure to the Company resulting from the transactions and allow the Company to receive a variable rate of interest. The interest rate swaps pay and receive interest based on a one-month SOFR floating rate plus a credit spread, with payments being calculated on the notional amount. During the second quarter of 2023, the Company transitioned the majority of these interest rate swap contracts to SOFR as the reference rate. For discussion related to reference rate reform, please refer to Accounting Standards Adopted within Note 3— Recent Accounting and Regulatory Pronouncements. The interest rate swaps are settled monthly with varying maturities.

The variation margin settlement payment and the related derivative instruments fair value are considered a single unit of account for accounting and financial reporting purposes. Depending on the net position of the swaps with LCH and CME, the fair value, net of the variation margin, is reported in Derivative Assets or Derivative Liabilities on the Consolidated Balance Sheets. In addition, the expense or income attributable to the variation margin for the centrally cleared swaps with LCH and CME is reported in Noninterest Income, specifically within Correspondent and Capital Markets Income. The daily settlement of the derivative exposure does not change or reset the contractual terms of the instrument.

​

As the interest rate swaps associated with this program do not meet the strict hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. As of September 30, 2023 and December 31, 2022, the interest rate swaps had an aggregate notional amount of approximately $22.3 billion and $20.9 billion, respectively. At September 30, 2023, the fair value of the interest rate swap derivatives is recorded in Other Assets at $210.5 million and in Other Liabilities at $1.3 billion. The fair value of derivative assets at September 30, 2023 was reduced by $1.0 billion in variation margin payments applicable to swaps centrally cleared through LCH and CME. At December 31, 2022, the fair value of the interest rate swap derivatives was recorded in Other Assets at $209.8 million and Other Liabilities at $1.0 billion. The fair value of derivative assets at December 31, 2022 was reduced by $824.3 million in variation margin payments applicable to swaps centrally cleared through LCH and CME. All changes in fair value are recorded through earnings within Correspondent and Capital Markets Income, a component of Noninterest Income on the Consolidated Statements of Net Income. There was a net gain of $587,000 and $599,000 recorded on these derivatives for the three and nine months ended September 30, 2023, respectively. There was a net loss of $3,000 and a net gain of $107,000 recorded on these derivatives for the three and nine months ended September 30, 2022, respectively. As of September 30, 2023, we provided $226.6 million of cash collateral on the counterparty, which is included in Cash and Cash Equivalents on the Consolidated Balance Sheets as Deposits in Other Financial Institutions (Restricted Cash). We also provided $100.1 million in investment securities at market value as collateral on the counterparty, which is included in Investment Securities – Available for Sale. Counterparties provided $102.4 million of cash collateral to the Company to secure swap asset positions that were not centrally cleared, which is included in Interest-bearing Deposits within Total Liabilities on the Consolidated Balance Sheets.

​

Balance Sheet Economic Hedge

​

During the third quarter of 2023, management began executing a series of short-term interest rate hedges to address monthly accrual mismatches related to the Company’s Assumable Rate Conversion (“ARC”) program and its transition from LIBOR to SOFR after June 30, 2023. The Company is required to execute the correspondent side of its back-to-back swaps with customers with the central clearinghouses (CME or LCH). Term SOFR was not available to execute through CME and LCH, and therefore, management elected to convert to the CME-eligible daily SOFR. Because many of the respondent bank customers converted to Term SOFR, this created interest rate basis risk. To address this risk, monthly interest rate hedges were executed to minimize the impact of accrual mismatches between the monthly Term SOFR used by the customer and the daily SOFR rates used by the central clearinghouses.

​

​

40

Table of Contents

As of September 30, 2023, the Company maintained an aggregate notional amount of $1.2 billion short-term interest rate hedges that were accounted for as economic hedges. As noted above, the derivatives protect the Company from interest rate risk caused by changes in the term and daily SOFR accrual mismatches. The fair value of these hedges is recorded in either Other Assets or in Other Liabilities depending on the position of the hedge with the offset recorded in Correspondent Banking and Capital Market Income, a component of Noninterest Income on the Consolidated Statements of Net Income. There was a net gain of $2,000 for these derivatives for the three and nine months ended September 30, 2023. The Company did not have any of these short-term interest rate hedges at December 31, 2022.

​

Foreign Exchange

​

The Company may enter into foreign exchange contracts with customers to accommodate their need to convert certain foreign currencies into U.S. Dollars. To offset the foreign exchange risk, the Company may enter into substantially identical agreements with an unrelated market counterparty to hedge these foreign exchange contracts. At September 30, 2023 and December 31, 2022, there were no outstanding contracts or agreements related to foreign currency. If there were foreign currency contracts outstanding at September 30, 2023, the fair value of these contracts would be included in Other Assets and Other Liabilities in the accompanying Consolidated Balance Sheets. All changes in fair value are recorded as other noninterest income. There was no gain or loss recorded related to the foreign exchange derivative for the three and nine months ended September 30, 2023 and 2022.

​

Mortgage Banking

​

The Company also has derivatives contracts that are not classified as accounting hedges to mitigate risks related to the Company’s mortgage banking activities. These instruments may include financial forwards, futures contracts, and options written and purchased, which are used to hedge MSRs; while forward sales commitments are typically used to hedge the mortgage pipeline. Such instruments derive their cash flows, and therefore their values, by reference to an underlying instrument, index or referenced interest rate. The Company does not elect hedge accounting treatment for any of these derivative instruments and as a result, changes in fair value of the instruments (both gains and losses) are recorded in the Company’s Consolidated Statements of Net Income in Mortgage Banking Income.

​

Mortgage Servicing Rights (“MSRs”)

​

Derivatives contracts related to MSRs are used to help offset changes in fair value and are written in amounts referred to as notional amounts. Notional amounts provide a basis for calculating payments between counterparties but do not represent amounts to be exchanged between the parties and are not a measure of financial risk. On September 30, 2023, we had derivative financial instruments outstanding with notional amounts totaling $44.0 million related to MSRs, compared to $35.0 million on December 31, 2022. The estimated net fair value of the open contracts related to the MSRs was recorded as a loss of $819,000 at September 30, 2023, compared to a loss of $163,000 at December 31, 2022.

Note 18 — Capital Ratios

​

The Company is subject to regulations with respect to certain risk-based capital ratios. These risk-based capital ratios measure the relationship of capital to a combination of balance sheet and off-balance sheet risks. The values of both balance sheet and off-balance sheet items are adjusted based on the rules to reflect categorical credit risk. In addition to the risk-based capital ratios, the regulatory agencies have also established a leverage ratio for assessing capital adequacy. The leverage ratio is equal to Tier 1 capital divided by total consolidated on-balance sheet assets (minus amounts deducted from Tier 1 capital). The leverage ratio does not involve assigning risk weights to assets.

41

Table of Contents

Under current regulations, the Company and the Bank are subject to a minimum ratio of common equity Tier 1 capital (“CET1”) to risk-weighted assets of 4.5% and a minimum required ratio of Tier 1 capital to risk-weighted assets of 6%. The minimum required leverage ratio is 4%. The minimum required total capital to risk-weighted assets ratio is 8%.

​

In order to avoid restrictions on capital distributions and discretionary bonus payments to executives, under the new rules a covered banking organization is also required to maintain a “capital conservation buffer” in addition to its minimum risk-based capital requirements. This buffer is required to consist solely of CET1, and the buffer applies to all three risk-based measurements (CET1, Tier 1 capital and total capital). The capital conservation buffer became fully phased-in on January 1, 2019 and consists of an additional amount of Tier 1 common equity equal to 2.5% of risk-weighted assets.

​

The Bank is also subject to the regulatory framework for prompt corrective action, which identifies five capital categories for insured depository institutions (well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized) and is based on specified thresholds for each of the three risk-based regulatory capital ratios (CET1, Tier 1 capital and total capital) and for the leverage ratio.

​

The following table presents actual and required capital ratios as of September 30, 2023 and December 31, 2022 for the Company and the Bank under the current capital rules. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations.

In accordance with ASU No. 2016-13, the Company applied the provisions of the standard using the modified retrospective method as a cumulative-effect adjustment to retained earnings. Related to the implementation of ASU 2016-13, the Company recorded additional allowance for credit losses for loans of $54.4 million, deferred tax assets of $12.6 million, an additional reserve for unfunded commitments of $6.4 million and an adjustment to retained earnings of $44.8 million. Instead of recognizing the effects from ASU 2016-13 at adoption, the standard included a transitional method option for recognizing the adoption date effects on the Company’s regulatory capital calculations over a three-year phase-in. In March 2020, in response to the COVID-19 pandemic, the regulatory agencies provided an additional transitional method option of a two-year deferral for the start of the three-year phase-in of the recognition of the adoption date effects of ASU 2016-13 along with an option to defer the current impact on regulatory capital calculations of ASU 2016-13 during the first two years (“5-year method”). Under this 5-year method, the Company would recognize an estimate of the previous incurred loss method for determining the allowance for credit losses in regulatory capital calculations and the difference from the CECL method would be deferred for two years. After two years, the effects from adoption date and the deferral difference from the first two years of applying CECL would be phased-in over three years using the straight-line method. The regulatory rules provided a one-time opportunity at the end of the first quarter of 2020 for covered banking organizations to choose its transition option for CECL. The Company chose the 5-year method and is deferring the recognition of the effects from adoption date and the CECL difference from the first two years of application. This amount was fixed as of December 31, 2021, and that amount began the three-year phase out in the first quarter of 2022 with 50% being phased out in 2023.

Note 19 — Goodwill and Other Intangible Assets

​

The carrying amount of goodwill was $1.9 billion at September 30, 2023 and December 31, 2022. The Company’s other intangible assets, consisting of core deposit intangibles, noncompete intangibles, and client list intangibles are included on the face of the balance sheet.

The Company last completed its annual valuation of the carrying value of its goodwill as of October 31, 2022 and determined there was no goodwill impairment. In between annual impairment analyses, we monitor for any triggering events that may impact the Company’s goodwill.

​

The following is a summary of gross carrying amounts and accumulated amortization of other intangible assets:

​

Accumulated amortization | ​ |  | (179,361) | ​ |  | (158,419) | ​
​ | ​ | $ | 95,094 | ​ | $ | 116,450 | ​

​

Amortization expense totaled $6.6 million and $20.9 million, for the three and nine months ended September 30, 2023, compared to $7.8 million and $25.2 million for the three and nine months ended September 30, 2022. Other intangibles are amortized using either the straight-line method or an accelerated basis over their estimated useful lives, with lives generally between two and 15 years.

​

The Company elected to apply fair value accounting to the Company’s SBA servicing asset. The change in fair value of the SBA servicing asset is recorded in SBA Income, a component of Noninterest Income on the Consolidated Statements of Income, during each applicable reporting period. As a result of the fair value accounting treatment, the Company does not amortize the SBA servicing asset and therefore excluded the SBA servicing asset from the future amortization expense table presented below. The fair value of the SBA servicing asset was $5.7 million and $6.1 million, respectively, at September 30, 2023 and December 31, 2022.

Note 20 — Mortgage Loan Servicing, Origination, and Loans Held for Sale

​

The portfolio of residential mortgages serviced for others, which is not included in the accompanying Consolidated Balance Sheets the portfolio of residential mortgages serviced for others, was $6.6 billion, as of September 30, 2023 and December 31, 2022. Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts and disbursing payments to investors. The amount of contractually specified servicing fees we earned during the three and nine months ended September 30, 2023 and September 30, 2022 were $4.1 million, $12.4 million, $4.2 million, and $12.1 million, respectively. Servicing fees are recorded in Mortgage Banking Income in our Consolidated Statements of Income.

​

At September 30, 2023 and December 31, 2022, MSRs were $89.5 million and $86.6 million on our Consolidated Balance Sheets, respectively. MSRs are recorded at fair value with changes in fair value recorded as a component of Mortgage Banking Income in the Consolidated Statements of Net Income. The market value adjustments related to MSRs recorded in Mortgage Banking Income for the three and nine months ended September 30, 2023 and September 30, 2022 were gains of $1.8 million and $2.5 million, compared with gains of $2.7 million and $18.3 million, respectively. The Company has used various free standing derivative instruments to mitigate the income statement effect of changes in fair value resulting from changes in market value adjustments, in addition to changes in valuation inputs and assumptions related to MSRs.

​

See Note 15 — Fair Value for the changes in fair value of MSRs. The following table presents the changes in the fair value of the MSR and offsetting hedge.

Net effect on Consolidated Statements of Net Income | ​ | $ | (2,951) | ​ | $ | (3,441) | ​ | $ | (8,174) | ​ | $ | (7,741) | ​ | ​

​

The fair value of MSRs is highly sensitive to changes in assumptions and is determined by estimating the present value of the asset’s future cash flows utilizing market-based prepayment rates, discount rates and other assumptions validated through comparison to trade information, industry surveys and with the use of independent third-party appraisals. Changes in prepayment speed assumptions have the most significant impact on the fair value of MSRs. Generally, as interest rates decline, mortgage loan prepayments accelerate due to increased refinance activity, which results in a decrease in the fair value of the MSR. Measurement of fair value is limited to the conditions existing and the assumptions utilized as of a particular point in time, and those assumptions may not be appropriate if applied at a different time. See Note 15 — Fair Value for additional information regarding fair value.

​

The sensitivity calculations above are hypothetical and should not be considered predictive of future performance. Changes in fair value based on adverse changes in assumptions generally cannot be extrapolated because the relationship of the changes in assumptions to fair value may not be linear. The effects of an adverse variation in a particular assumption on the fair value of the MSRs as disclosed in the table above is calculated without changing any other assumptions. In reality, changes in one factor may result in adjusting other factors, which may magnify or contract the effects of the change.

​

Whole loan sales were $259.2 million and $667.9 million for the three and nine months ended September 30, 2023, compared to $272.8 million and $1.4 billion for the three and nine months ended September 30, 2022. For the three and nine months ended September 30, 2023, $210.2 million and $534.3 million, or 81.1% and 80.0%, respectively, were sold with the servicing rights retained by the Company, compared to $216.1 million and $1.1 billion, or 79.2% and 77.2%, respectively, for the three and nine months ended September 30, 2022.

​

The Company retains no beneficial interests in these sales, but may retain the servicing rights for the loans sold. The risks related to the sold loans with the retained servicing rights due to a representation or warranty violation such as noncompliance with eligibility or servicing requirements, or customer fraud, that should have been identified in a loan file review are disclosed in Note 1 — Summary of Significant Accounting Policies, under the “Loans Held for Sale” section, of the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. The Company is obligated to subsequently repurchase a loan if such representation or warranty violation is identified by the purchaser. The aggregated principal balances of loans repurchased for the nine months ended September 30, 2023 and 2022 were approximately $975,000 and $6,708,000 respectively. There were approximately $6,000 and $73,000 in loss reimbursement and settlement claims paid in the nine months ended September 30, 2023 and 2022.

​

Loans held for sale have historically been comprised of residential mortgage loans awaiting sale in the secondary market, which generally settle in 15 to 45 days. Loans held for sale were $27.4 million and $29.0 million at September 30, 2023 and December 31, 2022, respectively. Please see Note 15 — Fair Value, under the “Fair Value Option”, section in this Quarterly Report on Form 10-Q for summary of the fair value and the unpaid principal balance of loans held for sale and the changes in fair value of these loans.

Note 21 — Short-Term Borrowings

Securities Sold Under Agreements to Repurchase (“Repurchase agreements”)

​

Repurchase agreements represent funds received from customers, generally on an overnight or continuous basis, which are collateralized by investment securities owned or, at times, borrowed and re-hypothecated by the Company. Repurchase agreements are subject to terms and conditions of the master repurchase agreements between the Company and the client and are accounted for as secured borrowings. Repurchase agreements are included in federal funds purchased and securities sold under agreements to repurchase on the consolidated balance sheets. At September 30, 2023 and December 31, 2022, our repurchase agreements totaled $259.8 million and $342.8 million, respectively. All of our repurchase agreements were overnight or continuous (until-further-notice) agreements at September 30, 2023 and December 31, 2022. These borrowings were collateralized with government, government-sponsored enterprise, or state and political subdivision-issued securities with a market value of $404.3 million and $443.2 million at September 30, 2023 and December 31, 2022, respectively. Declines in the value of the collateral would require us to increase the amounts of securities pledged.

​

Federal Funds Purchased

​

Federal funds purchased are generally overnight daily borrowings with no defined maturity date. At September 30, 2023 and December 31, 2022, our federal funds purchased totaled $253.5 million and $213.6 million, respectively.

​

Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) Borrowing

​

The Company has from time-to-time entered into borrowing agreements with the FHLB and FRB. Borrowings under these agreements are collateralized by stock in the FHLB, qualifying first and second mortgage residential loans, investment securities, and commercial real estate loans under a blanket-floating lien.

​

As of September 30, 2023 and December 31, 2022, the Company had no outstanding FHLB borrowings. Net eligible loans of the Company pledged via a blanket lien to the FHLB for advances and letters of credit at September 30, 2023, were approximately $11.2 billion (collateral value of $7.2 billion) and investment securities and cash pledged were approximately $651.9 million (collateral value of $552.2 million). This allows the Company a total borrowing capacity at the FHLB of approximately $7.8 billion. After accounting for letters of credit totaling $2.1 million, the Company had unused net credit available with the FHLB in the amount of approximately $7.8 billion at September 30, 2023. The Company also has a total borrowing capacity at the FRB of $1.9 billion at September 30, 2023 secured by a blanket lien on $2.8 billion (collateral value of $1.9 billion) in net eligible loans of the Company. The Company had no outstanding borrowings with the FRB at September 30, 2023 or December 31, 2022.

Note 22 — Stock Repurchase Program

On April 27, 2022, the Company’s Board of Directors approved a stock repurchase program (“2022 Stock Repurchase Program”) authorizing the Company to repurchase up to 3,750,000 of the Company’s common shares along with the remaining authorized shares of 370,021 from the Company’s 2021 stock repurchase program (“2021 Stock Repurchase Plan”) for a total authorization of 4,120,021 shares. The Company did not repurchase any shares through the 2022 Stock Repurchase Program during 2022 or during the nine months ended September 30, 2023. For the three and nine months ended September 30, 2023, a total of 5,097 and 103,190 shares, respectively, were repurchased under arrangements authorized by our stock-based compensation plans and Board of Directors, whereby officers or directors may sell shares to the Company in order to pay for the exercises of stock options or for income taxes owed on vesting shares of restricted stock. These shares were not purchased under the 2022 Stock Repurchase Plan. During the nine months ended September 30, 2022, before the approval of the 2022 Stock Repurchase Program, the Company repurchased a total of 1,312,038 shares at a weighted average price of $83.99 per share pursuant to the 2021 Stock Repurchase Plan.

This Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) relates to the financial statements contained in this Quarterly Report beginning on page 3. For further information, refer to the MD&A appearing in the Annual Report on Form 10-K for the year ended December 31, 2022. Results for the three and nine months ended September 30, 2023 are not necessarily indicative of the results for the year ending December 31, 2023 or any future period.

​

Unless otherwise mentioned or unless the context requires otherwise, references to “SouthState,” the “Company” “we,” “us,” “our” or similar references mean SouthState Corporation and its consolidated subsidiaries. References to the “Bank” means SouthState Corporation’s wholly owned subsidiary, SouthState Bank, National Association, a national banking association.

Overview

​

SouthState is a financial holding company headquartered in Winter Haven, Florida, and was incorporated under the laws of South Carolina in 1985. We provide a wide range of banking services and products to our customers through our Bank. The Bank operates SouthState|Duncan-Williams, a registered broker-dealer headquartered in Memphis, Tennessee that serves primarily institutional clients across the U.S. in the fixed income business. The Bank also operates SouthState Advisory, Inc., a wholly owned registered investment advisor, and CBI Holding Company, LLC (“CBI”), which in turn owns Corporate Billing, a transaction-based finance company headquartered in Decatur, Alabama that provides factoring, invoicing, collection and accounts receivable management services to transportation companies and automotive parts and service providers nationwide. The holding company also owns SSB Insurance Corp., a captive insurance subsidiary pursuant to Section 831(b) of the U.S. Tax Code.

​

At September 30, 2023, we had approximately $45.0 billion in assets and 5,156 full-time equivalent employees. Through our Bank branches, ATMs and online banking platforms, we provide our customers with a wide range of financial products and services, through a six (6) state footprint in Alabama, Florida, Georgia, North Carolina, South Carolina and Virginia. These financial products and services include deposit accounts such as checking accounts, savings and time deposits of various types, safe deposit boxes, bank money orders, wire transfer and ACH services, brokerage services and alternative investment products such as annuities and mutual funds, trust and asset management services, loans of all types, including business loans, agriculture loans, real estate-secured (mortgage) loans, personal use loans, home improvement loans, automobile loans, manufactured housing loans, boat loans, credit cards, letters of credit, home equity lines of credit, treasury management services, and merchant services.

​

We also operate a correspondent banking and capital markets division within our national bank subsidiary, of which the majority of its bond salesmen, traders and operational personnel are housed in facilities located in Atlanta, Georgia, Memphis, Tennessee, Walnut Creek, California, and Birmingham, Alabama. This division’s primary revenue generating activities are related to its capital markets division, which includes commissions earned on fixed income security sales, fees from hedging services, loan brokerage fees and consulting fees for services related to these activities; and its correspondent banking division, which includes spread income earned on correspondent bank deposits (i.e., federal funds purchased) and correspondent bank checking account deposits and fees from safe-keeping activities, bond accounting services for correspondents, asset/liability consulting related activities, international wires, and other clearing and corporate checking account services.

​

We have pursued, and continue to pursue, a growth strategy that focuses on organic growth, supplemented by acquisitions of select financial institutions, or branches in certain market areas.

Table of Contents

The following discussion describes our results of operations for the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022 and also analyzes our financial condition as of September 30, 2023 as compared to December 31, 2022. Like most financial institutions, we derive most of our income from interest we receive on our loans and investments. Our primary source of funds for making these loans and investments is our deposits, on which we may pay interest. Consequently, one of the key measures of our success is the amount of our net interest income, or the difference between the income on our interest-earning assets, such as loans and investments, and the expense on our interest-bearing liabilities, such as deposits. Another key measure is the spread between the yield we earn on these interest-earning assets and the rate we pay on our interest-bearing liabilities.

Of course, there are risks inherent in all loans, as such, we maintain an allowance for credit losses, otherwise referred to herein as ACL, to absorb probable losses on existing loans that may become uncollectible. We establish and maintain this allowance by charging a provision for credit losses against our operating earnings. In the following discussion, we have included a detailed discussion of this process.

​

In addition to earning interest on our loans and investments, we earn income through fees and other services we charge to our customers. We incur costs in addition to interest expense on deposits and other borrowings, the largest of which is salaries and employee benefits. We describe the various components of this noninterest income and noninterest expense in the following discussion.

​

The following sections also identify significant factors that have affected our financial position and operating results during the periods included in the accompanying financial statements. We encourage you to read this discussion and analysis in conjunction with the financial statements and the related notes and the other statistical information also included in this report.

Recent Events

Regulatory Considerations

​

In response to the recent bank failures, the FDIC approved a notice of proposed rulemaking to implement a special assessment to recover the losses to the FDIC’s Deposit Insurance Fund. The FDIC is proposing to collect the special assessment at an annual rate of approximately 12.5 basis points over eight quarterly assessment periods beginning with the first quarterly assessment period of 2024. Under the proposal, the base for the special assessment will be equal to an insured depository institution’s (IDI’s) estimated uninsured deposits reported as of December 31, 2022, adjusted to exclude the first $5 billion. Under the current FDIC proposal, the Company estimates the special assessment will equate to a quarterly special assessment of $3.0 million, or $23.9 million for the two-year special assessment period, which would be recognized at the time the final rule is adopted. The special assessment rate is subject to change prior to any final rule depending on any adjustments to the loss estimate, mergers or failures, or amendments to reported estimates of uninsured deposits.

​

On October 25, 2023, the Federal Reserve released a notice of proposed rulemaking that would lower the maximum interchange fee that a large debit card issuer can receive on a debit card transaction. Under the proposal, initially the base component would decrease from 21.0 cents to 14.4 cents, the ad valorem component would decrease from 5.0 basis points to 4 basis points multiplied by the value of the transaction, and the fraud-prevention adjustment would increase from 1.0 cents to 1.3 cents for debit card transactions performed from the effective date of the final rule to June 30, 2025. In addition, the proposal would adopt an approach for future adjustments to the interchange fee cap, which would occur every other year based on issuer cost data gathered from large debit card issuers. We will continue to monitor the status of the proposed rule and are in the process of evaluating this proposed rulemaking and assessing the scale of its adverse impact on the Company and Bank if adopted as proposed.

​

Liquidity and Capital

​

During 2023, the financial markets experienced some volatility in response to a small number of regional bank failures resulting from deposit runs generally related to high concentrations in particular customer segments, high levels of uninsured deposits and failures in interest rate risk management.

​

Table of Contents

Deposit flows are significantly influenced by general and local economic conditions, changes in prevailing interest rates, internal pricing decisions and competition. Our deposits are primarily obtained from depositors located around our branch footprint, and we believe that we have attractive opportunities to capture additional retail and commercial deposits in our markets, in addition to having access to brokered deposits. At September 30, 2023, we had $36.9 billion in total deposits, of which approximately 70% were insured or collateralized. Our deposit base is comprised of 1.4 million accounts with an average deposit size of $26,000. Our top 10 and 20 deposit relationships represent 3% and 4%, respectively, of total deposits.

​

In addition to deposits, we have other contingency funding sources available to the Bank. At September 30, 2023, our Bank had a total FHLB credit facility of $7.8 billion, $2.1 million in FHLB letters of credit outstanding at quarter-end, leaving $7.8 billion in availability on the FHLB credit facility. In addition, our Bank had $1.9 billion of credit available at the Federal Reserve Bank’s discount window and total federal funds credit lines of $300.0 million with no balances outstanding at quarter-end. The Bank also has an internal limit on brokered deposits of 15% of total deposits which would allow capacity of $5.5 billion as of September 30, 2023. The Bank had $1.1 billion of outstanding brokered deposits at the end of the quarter leaving $4.4 billion in available capacity. All of these resources would provide an additional $14.4 billion in funding if the Bank needed additional liquidity. In addition, the Bank also has $3.7 billion in market value of unpledged securities at September 30, 2023 that can be pledged to obtain additional funds, if necessary. The Company has a $100.0 million unsecured line of credit with U.S. Bank National Association with no balance outstanding at September 30, 2023. We believe that our liquidity position continues to be adequate and readily available.

​

In addition to adequate liquidity, the Company and Bank are considered well capitalized by all regulatory capital standards as it was significantly above the required capital levels as of September 30, 2023. The Company’s tier 1 leverage ratio, CET 1 risk-based capital ratio and total risk-based capital ratio were 9.34%, 11.47% and 13.76%, respectively, at September 30, 2023. The Bank’s Tier 1 leverage ratio, CET 1 risk-based capital ratio and total risk-based capital ratio were 9.96%, 12.25% and 13.44%, respectively, at September 30, 2023. As permitted, we elected to exclude accumulated other comprehensive income related to available for sale securities from Tier 1, CET 1 and total risk-based capital; however, even if our unrealized losses as of September 30, 2023 in our available for sale and held to maturity investment portfolios were recognized by selling the portfolios for liquidity purposes, all else being equal, our regulatory capital ratios would remain well in excess of the minimum standards and continue to be in the “well capitalized” regulatory classification.

Understanding our accounting policies is fundamental to understanding our consolidated financial position and consolidated results of operations. Accordingly, our significant accounting policies and changes in accounting principles and effects of new accounting pronouncements are discussed in Note 2 — Summary of Significant Accounting Policies and Note 3 — Recent Accounting and Regulatory Pronouncements of our consolidated financial statements in this Quarterly Report on Form 10-Q and in Note 1 — Summary of Significant Accounting Policies of our Annual Report on Form 10-K for the year ended December 31, 2022.

Results of Operations

​

Overview

​

We reported consolidated net income of $124.1 million, or diluted earnings per share (“EPS”) of $1.62, for the third quarter of 2023 as compared to consolidated net income of $133.0 million, or diluted EPS of $1.75, in the comparable period of 2022, a 6.7% decrease in consolidated net income and a 7.4% decrease in diluted EPS.

Table of Contents

The $8.9 million decrease in consolidated net income for the third quarter of 2023 compared to the same period of 2022 was the net result of the following items:

​

| ● | A $124.2 million increase in interest income, resulting from a $131.1 million increase in interest income from loans, partially offset by a $7.4 million decrease in interest income from federal funds sold and securities purchased under agreements to resell and interest-bearing deposits. The increase in loans was mainly due to the increase in yield in the current rising rate environment as the Federal Reserve Bank has raised it federal funds rate 525 basis points in 2022 and the first nine months of 2023. The increase in interest income from loans is also due to the increase in the average balance of loans of $3.5 billion through organic loan growth. The decline in interest income from federal funds sold, securities purchased under agreements to resell and interest-bearing deposits was due to a decline in average balance of $2.6 billion as liquidity tightened in 2023 with a more competitive deposit market in the rising rate environment;

| ● | A $131.1 million increase in interest expense, which resulted from a $126.4 million increase in interest expense from deposits, a $2.8 million increase in interest expense in federal funds purchased and securities sold under agreements to repurchase, and a $1.9 million increase in interest expense from corporate and subordinated debentures and other borrowings. These increases in expense resulted mainly from an increase in costs of all categories of interest-bearing liabilities as interest rates have increased in 2022 and 2023. The increase in average cost of interest-bearing liabilities was particularly felt in 2023 with the stress in financial markets and liquidity as the average cost of interest-bearing liabilities increased 171 basis points compared to the fourth quarter of 2022;

| ● | An $8.8 million increase in the provision for allowance for credit losses, as the Company recorded provision for credit losses of $32.7 million during the third quarter of 2023 while recording a provision for credit losses of $23.9 million in the third quarter of 2022. In the third quarter of 2023, we recorded a higher provision for credit losses as economic forecasts reflected the continued stress of inflation and rising interest rates that began in 2022 along with tight labor markets and global uncertainty;

| ● | A $0.2 million decrease in noninterest income, primarily from a decline in correspondent banking and capital markets income of $3.5 million and SBA income of $3.4 million partially offset by an increase in other noninterest income of $3.1 million, in service charges on deposit accounts of $2.3 million and in bank owned life insurance income of $1.0 million (See Noninterest Income section on page 57 for further discussion);

| ● | A $2.2 million decrease in noninterest expense, which resulted primarily from a decrease in merger, branch consolidation and severance related expense of $13.5 million and amortization of intangibles of $1.2 million. These decreases were offset by increases in salaries and employee benefits of $6.6 million, in FDIC assessment and other regulatory charges of $2.3 million and in other noninterest expense of $2.5 million which was driven by an increase in business development and staff related expense of $0.9 million, an increase in expense related to our earnings credit program for certain deposit accounts of $2.4 million and an increase in donation expense of $1.9 million partially offset by a decline in check and digital fraud charges of $1.3 million and loan expenses of $1.4 million. (See Noninterest Expense section on page 59 for further discussion; and

| ● | A $4.9 million decrease in the provision for income taxes primarily due to the change in pretax book income between the two quarters. The Company recorded pretax book income of $157.3 million in the third quarter of 2023 compared to pretax book income of $171.1 million in the third quarter of 2022. Our effective tax rate was 21.08% for the three months ended September 30, 2023 compared to 22.23% for the three months ended September 30, 2022.

​

Our quarterly efficiency ratio increased to 54.0% in the third quarter of 2023 compared to 53.1% in the third quarter of 2022. The increase in the efficiency ratio compared to the third quarter of 2022 was the result of the 2.0% decrease in the total of tax-equivalent net interest income and noninterest income being greater than the decrease in noninterest expense (excluding amortization of intangibles) of 0.4%. The decrease in income was mainly attributable to a 2.4% decrease in tax-equivalent net interest income due to an increase in interest expense on interest-bearing liabilities during 2023 resulting from the rising rate environment.

​

Basic and diluted EPS were $1.63 and $1.62, respectively for the third quarter of 2023, compared to $1.76 and $1.75, respectively for the third quarter of 2022. The decrease in basic and diluted EPS was due to a 6.7% decrease in net income in the third quarter of 2023 compared to the same period in 2022, partially offset by an increase in average basic common shares of 0.7%. The decrease in net income in the third quarter of 2023 was mainly attributable to lower net interest income resulting from an increase in interest expense on interest-bearing liabilities due to rising rate environment, along with higher provision for credit losses compared to the third quarter of 2022.

​

| ● | For the three months ended September 30, 2023, the return on average assets declined compared to the same period in 2022. This decrease was primarily due to the decrease in net income of $8.9 million, or 6.7%, which was attributable to lower net interest income of $7.0 million due to an increase in the cost of interest-bearing liabilities resulting from the rising rate environment, and higher provision for credit losses of $8.8 million as economic forecasts continue to reflect the continued stress from inflation and tightening of labor markets. Average assets decreased for the three months ended September 30, 2023 from the same period in 2022 or 0.3%, as interest-earning cash and cash equivalents declined $2.6 billion and investment securities declined $991.6 million as liquidity has tightened in 2023. For the nine months ended September 30, 2023, the return on average assets increased as net income was higher by $35.0 million, or 9.9%, compared to the nine months ended September 30, 2022.

| ● | For the three months ended September 30, 2023, the return on average equity and the return on average tangible equity declined compared to the same periods in 2022. These decreases were primarily due to lower net income of 6.7% and net income adjusted for the amortization of intangibles of 7.0%, along with an increase in average equity of 4.0% and tangible equity of 7.7%. For the nine months ended September 30, 2023, the return on average equity and the return on average tangible equity increased primarily due to higher net income of $35.0 million, or 9.9%, being greater than the increase in average tangible equity of $165.6 million, or 5.4%.

| ● | Equity to assets ratios was 11.63% for the quarter ended September 30, 2023, an increase of 0.55% from September 30, 2022, which was due to the increase in total equity of 6.3% resulting from the net income earned during the last twelve months being greater than the increase in total assets of 1.3% from September 30, 2022.

| ● | Dividend payout ratios were 31.84% and 29.78% for the three- and nine-month periods ending September 30, 2023, respectively, and 28.44% and 30.82% for the three- and nine-month periods ending September 30, 2022, respectively. The increase in the dividend payout ratio for the three months period ending September 30, 2023 was due the 6.7% decrease in net income along with total dividends paid during the current quarter increasing 4.5% compared to the same period in 2022. The dividend payout ratio for the nine months period ending September 30, 2023 decreased due to a higher increase in net income of 9.9% compared to an increase in total dividends paid of 6.2% when compared to the same period in 2022.

Net Interest Income and Margin

​

Non-Tax Equivalent (“TE”) net interest income decreased $7.0 million, or 1.9%, to $355.4 million in the third quarter of 2023 compared to $362.3 million in the same period in 2022. Interest-earning assets averaged $40.4 billion during the three months period ended September 30, 2023 compared to $40.5 billion for the same period in 2022, a decrease of $74.8 million, or 0.2%. Interest-bearing liabilities averaged $26.5 billion during the three months period ended September 30, 2023 compared to $24.8 billion for the same period in 2022, an increase of $1.8 billion, or 7.2%. Non-TE net interest income increased $158.7 million, or 16.9%, to $1.1 billion in the nine months ended September 30, 2023 compared to $939.7 million in the same period in 2022. Interest-earning assets averaged $40.0 billion during the nine months ended September 30, 2023 and 2022. Interest-bearing liabilities averaged $25.7 billion during the nine months ended September 30, 2023 compared to $25.0 billion for the same period in 2022, an increase of $683.8 million, or 2.7%.

The Federal Reserve made four 25 basis-point rate increases in 2023, the most recent in late July 2023, resulting in a range of 5.25% to 5.50% at September 30, 2023. As a result, the Company operated under an increasing rate environment for the first nine months of 2023 while it operated under a comparatively lower rate environment in the first nine months of 2022. Some key highlights are outlined below:

​

| ● | Both the non-TE and TE net interest margin decreased by 6 basis points and 8 basis points, respectively, in the third quarter of 2023 compared to the same quarter of 2022. In the rising rate environment in 2022 and 2023, the net interest margin decreased as the cost of funds rose faster than the yield on interest-earning assets. The 195 basis points increase in the average cost of interest-bearing liabilities outpaced the 123 basis points increase in the average earnings from interest-earning assets. This was due to a $1.8 billion increase in the average balance of interest-bearing liabilities, while the average balance of interest-earning assets remained relatively constant at $40.4 billion during the third quarter of 2023 compared to $40.5 billion during the same period in 2022.

| ● | Non-TE yield on interest-earning assets for the third quarter of 2023 increased 123 basis points to 4.92% from the comparable period in 2022, primarily due to an increase in yields on all interest-earning assets as the Federal Reserve Bank raised interest rates 525 basis points starting late in first quarter of 2022. The increases in interest rates, in combination with the increase in the average balance of the higher yielding loan portfolio of $3.5 billion, along with the decline in the average balances of lower yielding interest-earning deposits and federal funds sold of $2.6 billion and investment securities of $991.6 million, affected the overall yield increase between the comparable periods.

| ● | The average cost of interest-bearing liabilities for the third quarter of 2023 increased 195 basis points from the same period in 2022. This increase was driven by the effects from the rising rate environment on the repricing of all deposit accounts, federal funds purchased and securities purchased with agreement to repurchase, trust preferred corporate debt and other borrowings. The average cost of interest-bearing deposits increased 195 basis points as the increase occurred in all deposit categories. The average cost of federal funds purchased and securities purchased with agreements to repurchase increased 308 basis points and 132 basis points, respectively, while the average cost of corporate and subordinated debentures increased 108 basis points. Other borrowings, consisting of FHLB advances had an average cost of 5.50% during the third quarter of 2023. The increase in overall average cost of interest-bearing liabilities for the third quarter of 2023 from the same period in 2022 was also a result of the change in deposit balances, shifting from lower-costing savings deposit accounts to higher-costing certificates and other time deposits and transaction and money market accounts. Our overall cost of funds, including noninterest-bearing deposits, was 1.52% for the three months ended September 30, 2023 compared to 0.14% for the three months ended September 30, 2022.

Investment Securities

​

The yield and interest earned on investment securities increased in the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022. The average balance of investment securities decreased $991.6 million and $518.3 million, respectively, for the three and nine months ended September 30, 2023 from the comparable periods in 2022. The yield on the investment securities increased 30 basis points and 40 basis points, respectively, during the three and nine months ended September 30, 2023 compared to the same periods in 2022. While the Bank decreased the size of its investment securities portfolio, the yield on the investment securities increased as a result of the higher interest rates during the three and nine months ended September 30, 2023, leading to higher interest income in 2023.

Loans

​

Interest earned on loans held for investment increased $131.1 million, to $443.3 million and increased $438.8 million to $1.3 billion, respectively, during the three and nine months ended September 30, 2023 from the comparable periods in 2022. Interest earned on loans held for investment included loan accretion income recognized during the three and nine months ended September 30, 2023 and 2022 of $4.1 million, $16.9 million, $9.6 million and $29.1 million, respectively, a decrease of $5.5 million and $12.1 million, respectively. Some key highlights for the quarter ended September 30, 2023 are outlined below:

| ● | Our non-TE yield on total loans increased 115 basis points in the third quarter of 2023 compared to the same period in 2022 due to a 124 basis-point increase in the yield on the non-acquired loan portfolio and a 116 basis-point increase in the yield on the acquired loan portfolio. These increases in both portfolios were due to the rising rate environment.

| o | The yield on the non-acquired loan portfolio increased 124 basis points to 5.37% in the third quarter of 2023 compared to 4.13% in the same period in 2022. Interest income on the non-acquired loan portfolio increased $136.4 million during the same period.

| ◾ | The yield and interest income on non-acquired loans increased due to the rising rate environment during 2022 and 2023. Both new loans and renewals have repriced in a higher rate environment resulting in a higher yield overall.

| ◾ | For the non-acquired loans, interest income also increased due to an increase in the average loan balance of $5.4 billion during the third quarter of 2023 compared to the same period in 2022, primarily through organic loan growth and renewals of acquired loans that are moved to our non-acquired loan portfolio.

| o | The yield on the acquired loan portfolio increased from 4.99% in the third quarter of 2022 to 6.15% in the same period in 2023. Interest income on the acquired loan portfolio declined $5.3 million.

| ◾ | The yield increased 116 basis points from the third quarter of 2022 due to the rising rate environment during 2022 and 2023 as the Federal Reserve increased interest rates 525 basis points.

| ◾ | Interest income on acquired loans decreased by $5.3 million, due to a decrease in the average balance of $1.9 billion. The decrease in average balance was mainly related to the impact from the paydowns and pay-offs of loans along with renewals of acquired loans that were moved to our non-acquired loan portfolio.

​

Interest-Bearing Liabilities

​

The quarter-to-date average balance of interest-bearing liabilities increased $1.8 billion, or 7.2%, in the third quarter of 2023 compared to the same period in 2022. Overall cost of funds, including demand deposits, increased by 138 basis points to 1.52% in the third quarter of 2023, compared to the same period in 2022. Some key highlights for the quarter ended September 30, 2023 compared to the same period in 2022 include:

​

| ● | The cost of interest-bearing deposits was 2.08% for the third quarter of 2023 compared to 0.13% for the same period in 2022.

| o | Interest expense on interest-bearing deposits increased by $126.4 million in the third quarter of 2023 compared to the same period in 2022 as interest expense on all interest-bearing deposit accounts increased. Interest expense on transaction and money market accounts, savings, and certificates and other time deposits increased $88.1 million, $1.4 million, and $36.9 million, respectively. The increase in the cost and interest expense was due to the repricing of deposits in the rising rate environment in 2022 and 2023 and the overall increase in average balance.

​

| o | The average balance of interest-bearing deposits increased by $1.8 billion as certificate and other time deposits and interest-bearing transaction accounts and money market accounts increased by $2.6 billion. This was offset by a decrease in savings accounts of $776.2 million. During the third quarter of 2023, the average balance of brokered deposits was $1.1 billion compared to $150.0 million for the same quarter in 2022. As customers moved funds from lower costing interest-bearing transaction accounts (excluding money market accounts) and savings accounts, seeking higher yields in the rising rate environment, the Company increased its balance in higher costing brokered time deposits, in-market time deposits and money market accounts starting in the first quarter of 2023. This shift from the lower costing interest-bearing transaction accounts and savings accounts to the higher costing time deposits and money market accounts increased both the overall cost of deposits and interest expense. Overall, interest-bearing deposits had been slower to reprice in the rising rate environment, however, the cost increased significantly in the first nine months of 2023 as competition for deposits increased.

| ● | The cost on the corporate and subordinated debt increased by 108 basis points to 6.09% for the three months ended September 30, 2023 compared to the same period in 2022, driven by the effects from the rising rate environment on the repricing of variable rate trust preferred corporate debt, even though the average balance slightly decreased.

| o | The interest expense from corporate and subordinated debt increased $1.1 million during the third quarter of 2023 compared to the same period in 2022.

| o | The average balance of corporate and subordinated debt decreased slightly by $373,000 due to the amortization of purchase accounting adjustment and debt issuance costs.

| ● | The cost of repurchase agreements was 1.52% for the third quarter of 2023 compared to 0.20% for the same period in 2022. The increase in cost was due to the rising interest rate environment.

| ● | The cost of federal funds purchased increased 308 basis points due to the rising rate environment. Although the average balance decreased by $4.1 million, the interest expense increased $1.8 million as the rates increased.

| ● | The cost of other borrowings, consisting of FHLB advances, for the three months ended September 30, 2023 was 5.50% and interest expense was $889,000. The Bank paid-off $400 million of FHLB advances during the third quarter of 2023 and had no outstanding balances as of September 30, 2023. There were no outstanding balances in other borrowings during the third quarter of 2022.

​

We continue to monitor and adjust rates paid on deposit products as part of our strategy to manage our net interest margin. Interest-bearing liabilities include interest-bearing transaction accounts, savings deposits, CDs, other time deposits, federal funds purchased, and other borrowings. Interest-bearing transaction accounts include NOW, HSA, IOLTA, and Market Rate checking accounts.

Noninterest-Bearing Deposits

​

Noninterest-bearing deposits are transaction accounts that provide our Bank with “interest-free” sources of funds. Average noninterest-bearing deposits decreased $2.6 billion, or 18.5%, to $11.4 billion in the third quarter of 2023 compared to $13.9 billion during the same period in 2022. Actual noninterest-bearing deposits declined $2.0 billion from December 31, 2022. This decline was due to both the rising rate environment as customers sought higher yields, in addition to some customers spreading deposit funds amongst institutions to achieve full deposit insurance coverage.

Noninterest Income

​

Noninterest income provides us with additional revenues that are significant sources of income. For the three months ended September 30, 2023 and 2022, noninterest income comprised 17.0%, and 16.8%, respectively, of total net interest income and noninterest income. For the nine months ended September 30, 2023 and 2022, noninterest income comprised 16.8%, and 20.7%, respectively, of total net interest income and noninterest income.

Noninterest income decreased slightly by $205,000, or 0.3%, during the third quarter of 2023 compared to the same period in 2022. This quarterly change in total noninterest income resulted from the following:

​

| ● | Correspondent banking and capital markets income in the third quarter of 2023 decreased by $3.5 million, or 21.4%, compared to the same quarter in 2022. The decline was mainly due to lower commissions and fees earned on fixed income security sales of $3.5 million during the third quarter of 2023 as the volume in sales declined compared to the same quarter of 2022.

| ● | SBA income decreased by $3.4 million, or 52.6% compared to the third quarter of 2022. SBA income includes changes in fair value of the servicing asset, loan servicing fees and gains on sale of SBA loans. The decrease in the third quarter of 2023 compared to the comparable period in 2022 was attributable to decreases in the net gain on sale of SBA loans, fair value of the SBA servicing asset and loan servicing fee income of $2.1 million, $1.1 million, and $220,000, respectively.

| ● | Other income increased by $3.1 million, or 160.1%, in the third quarter of 2023 compared to the same period in 2022, primarily due to approximately $2.9 million income recorded for tax refunds during the third quarter of 2023.

| ● | Service charges on deposit accounts were higher by $2.3 million, or 11.5%, in the third quarter of 2023 compared to the same period in 2022. This increase mainly consisted of an increase in deposit account maintenance fees of $2.1 million and in other retail fees of $290,000 including wire transfer fees and check sales commissions.

| ● | Mortgage banking income increased by $216,000, or 9.5%, during the current quarter compared to the same period of the prior year, which was comprised of a $442,000, or 60.6%, increase in mortgage servicing related income, slightly offset by a $225,000, or 14.7%, decrease in secondary market mortgage income net of the hedge. Mortgage production declined from $1.1 billion in the third quarter of 2022 to $521 million in the third quarter of 2023, while the Company allocated a higher percentage of its mortgage production to the secondary market compared to the same quarter in 2022. The allocation of mortgage production to the secondary market increased from 22% in the third quarter of 2022 to 47% in the third quarter of 2023. The allocation of mortgage production between portfolio and secondary market depends on the Company’s liquidity, market spreads and rate changes during each period and will fluctuate quarter to quarter. The decline in mortgage production in 2023 was mainly due to the rise in interest rates, which resulted in an overall decrease in mortgage banking income.

| o | The increase in mortgage servicing related income, net of the hedge, in the third quarter of 2023 was due to a $491,000 increase in the change in fair value of the MSR, including decay, net of a $49,000 decrease in servicing fee income. The increase in fair value of the MSR was primarily due to an increase in gains on the MSR hedge of $1.4 million, offset by a decrease in the change in fair value from interest rates of $898,000 and a $13,000 increase in MSR decay.

​

Table of Contents

| o | The decrease in mortgage income from the secondary market was comprised of a $1.6 million decline in gain on sale of mortgage loans, which is net of the commission expense related to mortgage production, offset by a $1.4 million increase in the change in fair value of the pipeline, loans held for sale and MBS forward trades. Mortgage commission expense was $2.9 million during the third quarter of 2023 compared to $2.4 million during the comparable period in 2022.

​

Noninterest income decreased by $24.4 million, or 9.9%, during the nine months ended September 30, 2023 compared to the same period in 2022. This change in total noninterest income resulted from the following:

​

| ● | Correspondent banking and capital markets income for 2023 decreased by $24.7 million, or 35.1%, compared to 2022 primarily due to the expense attributable to the variation margin payments for centrally cleared swaps, along with lower commissions and fees earned on fixed income security sales of $12.4 million during 2023 as the volume in sales declined compared to the same period in 2022. We recorded an expense of $28.8 million related to variation margin payments in 2023 compared to an expense of $5.7 million in 2022.

| ● | Mortgage banking income decreased by $7.2 million, or 39.1%, which was comprised of a $7.1 million, or 50.5%, decrease in secondary market mortgage income and a $111,000, or 2.6%, decrease in mortgage servicing related income. Mortgage production declined from $3.8 billion in the first nine months of 2022 to $1.8 billion in the first nine months of 2023 with the rise in mortgage rates accelerating during 2023, while allocating a higher percentage of its mortgage production and pipeline to the secondary market compared to 2022. The reduction in mortgage production resulted in lower mortgage income from the secondary market in 2023. The allocation of mortgage production between portfolio and secondary market depends on the Company’s liquidity, market spreads and rate changes during each period and will fluctuate quarter to quarter.

| o | During the first nine months of 2023, mortgage income from the secondary market comprised of a $17.3 million decline in gain on sale of mortgage loans, which is net of the commission expense related to mortgage production, offset by a $10.2 million increase in the change in fair value of the pipeline, loans held for sale and MBS forward trades. Mortgage commission expense was $6.5 million during the nine months ended September 30, 2023 compared to $11.3 million during the comparable period in 2022.

| o | The decrease in mortgage servicing related income, net of the hedge, in the nine months ended September 30, 2023 was due to a $434,000 decrease in the change in fair value of the MSR, including decay, offset by a $323,000 increase in servicing fee income. The decrease in fair value of the MSR was primarily due to a decrease in the change in fair value from interest rates of $15.8 million, offset by an increase in gains on the MSR hedge of $13.7 million and a $1.7 million decrease in MSR decay.

| ● | SBA income, including the impact from the change to fair value accounting, decreased by $4.3 million, or 30.8% in 2023 compared to 2022. The decrease was attributable to a decrease in gains on sale of SBA loans of $2.3 million and a decrease in the change in fair value of the SBA servicing asset of $2.1 million, partially offset by an increase in SBA servicing fee income of $146,000.

| ● | Debit, prepaid, ATM and merchant card related income was lower by $584,000, or 1.9%, in 2023 compared to 2022. The decrease in debit, ATM, prepaid and merchant card related income was driven by a decrease in debit/ATM fee income, net of card expense, of $665,000 due mainly to higher card expense of $1.9 million.

| ● | Service charges on deposit accounts were higher in 2023 by $5.2 million, or 8.6%, compared to 2022. The increase was mainly attributable to a $3.8 million increase in service charge account maintenance fees, a $967,000 increase in Non-Sufficient Fund (“NSF”) fees, and approximately $364,000 increase in other services charges in 2023 compared to 2022.

| ● | Other income increased by $4.5 million, or 86.1%, in 2023 compared to 2022. This increase was primarily due to approximately $2.9 million in income recorded for tax refunds during the third quarter of 2023, income of $960,000 from a legal settlement recorded during the first quarter of 2023, and an increase in income from prepaid cards of $608,000.

| ● | Bank owned life insurance income increased $2.5 million, or 14.4%, in 2023 compared to 2022. This increase was due to the purchase of $91.9 million of new policies since March of 2022 and the addition of $74.6 million in BOLI resulting from the acquisition of Atlantic Capital in the first quarter of 2022. In addition, the Company received approximately $573,000 proceeds on a BOLI policy during the third quarter of 2023.

Noninterest expense decreased by $2.2 million, or 0.9%, in the third quarter of 2023 as compared to the same period in 2022. The quarterly decrease in total noninterest expense primarily resulted from the following:

​

| ● | Salaries and employee benefits increased $6.6 million, or 4.7%, in the third quarter of 2023 compared to the same period in 2022. The increase was primarily due to an increase in salaries of $13.5 million which included annual salary increases of approximately $7.3 million and a decline in total deferred loan costs of $6.2 million. The reduction in deferred loan costs was driven by lower loan production. The overall increase in salaries and employee benefits was also due to an increase in commissions of $1.3 million, mainly attributable to higher commissions on loan sales related to ARC hedging. These increases were partially offset by declines in employee benefits of $5.0 million and incentives of $2.4 million. The reduction in employee benefits was mainly due to a $5.5 million reduction in liability related to our supplemental executive retirement and split dollar plans as higher interest rates drove up the discount rate used to value the liability.

| ● | FDIC assessment and other regulatory charges increased $2.3 million, or 37.0%, in the third quarter of 2023 compared to the same period in 2022. This increase was primarily due to an increase in the FDIC assessment rate in 2023 to bring the overall FDIC fund to 1.35x total deposit by the end of 2028. The increase also reflects changes in the Company’s size and complexity, along with the resulting effects in the Company’s liquidity compared to the second quarter of 2022.

| ● | Other noninterest expense increased $1.3 million, or 8.3%, compared to the nine months ended September 30, 2023. This increase was mainly attributable to a $2.4 million increase in earnings credit expense to Homeowners Association (“HOA”) customers and a $1.9 million increase in donations. The Bank provides a credit to HOA customers based on the average deposit balances held that reduces fees for other services provided. These increases were partially offset by approximately a $1.9 million decrease in fraud charge-offs and a $1.3 million decrease in tax penalties. The Company accrued tax penalty expenses related to information return reporting in late 2022. Some of the penalties have since been abated by the Internal Revenue Service (“IRS”), resulting the decrease in expense in 2023.

| ● | Business development and staff related expense increased $905,000, or 17.8%, in the third quarter of 2023 compared to the same period in 2022. This increase was mainly due to an increase in employee expenses including employee travel expense, convention and meeting expense, recruitment and relocation costs associated with the Company investing in new talent and employee education and training related costs.

| ● | Advertising and marketing expense increased $839,000, or 38.7%, in the third quarter 2023 compared to the same period in 2022, primarily due to media advertising production and placement related costs incurred in the third quarter of 2023.

| ● | Information services expense increased $714,000, or 3.4%, in the third quarter of 2023 compared to the same period in 2022. The increase was due to additional cost associated with the Company updating systems as it grows in size and complexity.

| ● | Merger, branch consolidation and severance related expense decreased $13.5 million, or 98.8%, in the third quarter of 2023 compared to the same period in 2022. The Company did not incur any merger expense pertaining to prior acquisitions during the third quarter of 2023, while it had a total of $7.5 million merger expense during the comparative period in 2022. The decrease also was due to lower branch consolidation related expense of $6.0 million.

| ● | Amortization of intangibles, which is related to the Company’s prior mergers, decreased $1.2 million, or 15.6%.

Noninterest expense increased by $21.1 million, or 3.0%, during the nine months ended September 30, 2023 compared to the same period in 2022. The categories and explanations for the fluctuations year-to-date, except the items discussed below, are similar to the ones noted above in the quarterly comparison.

| ● | Merger, branch consolidation and severance related expense decreased by $18.0 million, or 61.2%, compared to the nine months ended September 30, 2022. The decrease was primarily due to a $18.3 million decrease in merger expense pertaining to expenses related to the Atlantic Capital and CenterState mergers and a $7.3 million decrease in branch consolidation related expense in 2023 compared to 2022. These decreases were offset by severance related payments totaling $8.1 million related to restructuring costs recorded in March 2023.

| ● | Other noninterest expense increased $4.4 million, or 9.2%, compared to the nine months ended September 30, 2022. This increase was mainly attributable to a $6.2 million increase in earnings credit expense to HOA customers, a $2.6 million increase in state franchise and occupation tax payments, a $2.5 million increase in donations, and a $1.9 million increase due to a new subscription to a system that provides real-time financial market data analysis services. These increases were partially offset by a decrease in fraud charge-offs, tax penalties, digital banking losses, force placed insurance and miscellaneous operational charge-off related expenses totaling approximately $8.8 million.

Income Tax Expense

​

Our effective tax rate was 21.08% for the three months ended September 30, 2023 compared to 22.23% for the three months ended September 30, 2022. T he decrease in the effective rate for the quarter, when compared to the same period in the prior year, is mostly driven by a decrease in pretax income, disallowed interest expense, disallowed executive compensation, and an increase in the cash surrender value of BOLI policies, partially offset by an increase in tax-exempt interest income and non-deductible FDIC premiums.

​

Our effective tax rate for the first nine months of the year was 21.60% compared to 21.76% for the first nine months of 2022. The decrease in the year-to-date effective tax rate compared to the same period of 2022 was primarily driven by an increase in non-deductible FDIC premiums, disallowed executive compensation, and disallowed interest expense, partially offset by an increase in tax-exempt interest income and an increase in federal tax credits available.

Analysis of Financial Condition

Summary

Our total assets increased approximately $1.1 billion, or 2.4%, from December 31, 2022 to September 30, 2023, to approximately $45.0 billion. Within total assets, loans increased, $1.8 billion, or 6.1%, while investment securities decreased $845.3 million, or 10.3%, during the period. Within total liabilities, deposit growth was $584.6 million, or 1.6%, and derivative liabilities increased $217.7 million, or 21.1%. Total shareholder’s equity increased $156.1 million, or 3.1%. The increase in loans was due to organic growth. Deposit increase was due to growth in money market accounts of $2.4 billion, including $1.1 billion in reciprocal insured money market deposits and time deposits of $2.0 billion, including an increase in brokered time deposits of $908.9 million. These increases were offset by d eclines in noninterest-bearing, interest-bearing checking and savings accounts of $2.0 billion, $1.1 billion and $704.2 million, respectively. Our loan to deposit ratio was 87% and 83% at September 30, 2023 and December 31, 2022, respectively, while our percentage of noninterest-bearing deposit accounts to total deposits was 30% and 36%, respectively at September 30, 2023 and December 31, 2022.

Investment Securities

​

We use investment securities, our second largest category of earning assets, to generate interest income, provide liquidity, fund loan demand or deposit liquidation, and pledge as collateral for public funds deposits, repurchase agreements, derivative exposures and to augment borrowing capacity at the Federal Reserve Bank of Atlanta, and the Federal Home Loan Bank of Atlanta. At September 30, 2023, investment securities totaled $7.3 billion, compared to $8.2 billion at December 31, 2022, a decrease of $845.3 million, or 10.3%. At September 30, 2023, approximately 63.0% of the investment portfolio was classified as available for sale, approximately 34.5% was classified as held to maturity and approximately 2.5% was classified as other investments. During the nine months ended September 30, 2023, we purchased $188.9 million of capital stock with the Federal Home Loan Bank classified as other investment securities on the balance sheet of which we sold back $185.9 million. The net increase to the capital stock holding for the Federal Home Loan Bank of Atlanta of $3.0 million during the quarter was due to the increase in Federal Home Loan Bank borrowings. During the nine months ended September 30, 2023, we purchased $34.5 million of available for sale securities. There were no purchases of held to maturity securities during 2023. These purchases were offset by maturities, paydowns, sales and calls of investment securities totaling $861.6 million. Net amortization of premiums was $15.2 million in the first nine months of 2023.

​

At September 30, 2023, the unrealized net loss of the available for sale securities portfolio was $1.1 billion, or 19.0%, below its amortized cost basis, compared to an unrealized net loss of $889.3 million, or 14.3%, at December 31, 2022. At September 30, 2023, the unrealized net loss of the held to maturity securities portfolio was $521.3 million, or 20.6%, below its amortized cost basis, compared to an unrealized net loss of $433.1 million, or 16.1%, at December 31, 2022.

* Agency mortgage-backed securities (“MBS”), agency collateralized mortgage-obligations (“CMO”) and agency commercial mortgage-backed securities (“CMBS”) are guaranteed by the issuing government-sponsored enterprise (“GSE”) as to the timely payments of principal and interest. Except for Government National Mortgage Association securities, which have the full faith and credit backing of the United States Government, the GSE alone is responsible for making payments on this guaranty. While the rating agencies have not rated any of the MBS, CMO and CMBS issued, senior debt securities issued by GSEs are rated consistently as “Triple-A.” Most market participants consider agency MBS, CMOs and CMBSs as carrying an implied Aaa rating (S&P rating of AA+) because of the guarantees of timely payments and selection criteria of mortgages backing the securities. We do not own any private label mortgage-backed securities. The balances presented under the ratings above reflect the amortized cost of the investment securities.

At September 30, 2023, we had 1,249 investment securities (including both available for sale and held to maturity) in an unrealized loss position, which totaled $1.6 billion. At December 31, 2022, we had 1,311 investment securities (including both available for sale and held to maturity) in an unrealized loss position, which totaled $1.3 billion. The total number of investment securities with an unrealized loss position decreased by 62 securities, while the total dollar amount of the unrealized loss increased by $280.6 million. The level of unrealized losses within the Company available for sale and held to maturity securities portfolios is due to the overall increase in short and long-term interest rates in 2023.

All investment securities in an unrealized loss position as of September 30, 2023 continue to perform as scheduled. We have evaluated the securities and have determined that the decline in fair value, relative to its amortized cost, is not due to credit-related factors. In addition, we have the ability and intent to hold these securities within the portfolio until maturity or until the value recovers, and we believe that it is not more likely than not that we will be required to sell these securities prior to recovery. We continue to monitor all of our securities with a high degree of scrutiny. There can be no assurance that we will not conclude in future periods that conditions existing at that time indicate some or all of our securities may be sold or would require a charge to earnings as a provision for credit losses in such periods. Any charges as a provision for credit losses related to investment securities could impact cash flow, tangible capital or liquidity. See Note 2 — Summary of Significant Accounting Policies and Note 5 — Investment Securities for further discussion on the application of ASU 2016-13 on the investment securities portfolio.

​

As securities held for investment are purchased, they are designated as held to maturity or available for sale based upon our intent, which incorporates liquidity needs, interest rate expectations, asset/liability management strategies, and capital requirements. Although securities classified as available for sale may be sold from time to time to meet liquidity or other needs, it is not our normal practice to trade this segment of the investment securities portfolio. From time to time, the Bank may execute transactions to reposition the investment portfolio. Such activity has not expanded the broad asset classes used by the Bank. While management generally holds these assets on a long-term basis or until maturity, any short-term investments or securities available for sale could be converted at an earlier point, depending partly on changes in interest rates and alternative investment opportunities.

Approximately 85.9% of the investment portfolio is comprised of U.S. Treasury securities, U.S. Government agency securities, and U.S. Government Agency Mortgage-backed securities. These securities may be pledged to the Federal Home Loan Bank of Atlanta or the Federal Reserve Bank of Atlanta Discount Window or Bank Term Funding Program. Approximately 13.7% of the investment portfolio is comprised of municipal securities. A portion of the municipal bond portfolio may be pledged to the Federal Home Loan Bank of Atlanta subject to their credit approval. Approximately 94% of the municipal bond portfolio has ratings in the Double A or Triple A category.

​

Through September 30, 2023, we sold approximately $125.3 million of municipal securities given advantageous market conditions. The primary rationale for the sale was to reduce municipal and portfolio duration/price risk at an opportune moment in fixed income markets. As of September 30, 2023, the portfolio had an effective duration of 5.43 years. We continue to monitor duration risk and seek to align actual duration with the target range.

Other investment securities include primarily our investments in FHLB and FRB stock with no readily determinable market value. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value. As of September 30, 2023, we determined that there was no impairment on our other investment securities. As of September 30, 2023, other investment securities represented approximately $187.2 million, or 0.42% of total assets, and primarily consists of FHLB and FRB stock which totals $168.3 million, or 0.37% of total assets. There were no gains or losses on the sales of these securities for three and nine months ended September 30, 2023 and 2022, respectively.

Trading Securities

​

We have a trading portfolio associated with our Correspondent Bank Division and its subsidiary SouthState|Duncan-Williams. This portfolio is carried at fair value and realized and unrealized gains and losses are included in trading securities revenue, a component of Correspondent Banking and Capital Markets Income in our Consolidated Statements of Net Income. Securities purchased for this portfolio have primarily been municipal bonds, treasuries and mortgage-backed agency securities, which are held for short periods of time and totaled $114.2 million and $31.3 million, respectively, at September 30, 2023 and December 31, 2022.

Loans Held for Sale

​

The balance of mortgage loans held for sale decreased $1.5 million from December 31, 2022 to $27.4 million at September 30, 2023. Mortgage production in the third quarter of $521 million declined when compared to the fourth quarter of 2022 mortgage production of $693 million. Mortgage production has declined as mortgage rates have increased. The percentage of mortgage production sold into the secondary market increased in the third quarter of 2023 to 47% from 19% in the fourth quarter of 2022. The allocation of mortgage production between portfolio and secondary market depends on the Company’s liquidity, market spreads and rate changes during each period and will fluctuate over time.

Total loans, net of deferred loan costs and fees (excluding mortgage loans held for sale), increased by $1.8 billion, or 8.1% annualized, to $32.0 billion at September 30, 2023 compared to December 31, 2022. Our non-acquired loan portfolio increased by $3.0 billion, or 17.4% annualized, driven by organic growth. Consumer owner occupied loans, commercial non-owner occupied loans, commercial owner occupied real estate, commercial and industrial loans and home equity loans led the way with $1.2 billion, $888.8 million, $324.4 million, $372.4 million and $123.0 million in year-to-date loan growth, respectively, or 36.2%, 21.5%, 11.8%, 12.1% and 17.2% annualized growth, respectively. The acquired loan portfolio decreased by $1.1 billion, or 20.6% annualized. This decline in acquired loans was due to paydowns and payoffs in both the PCD and Non-PCD loan categories along with renewals of acquired loans that were moved to our non-acquired loan portfolio. The main categories that declined were commercial non-owner occupied loans, commercial owner occupied loans, commercial and industrial loans and construction and development loans with $259.4 million, $245.5 million, $227.6 million and $118.8 million in year-to-date loan decrease. Acquired loans as a percentage of total loans decreased to 19.5% and non-acquired loans as a percentage of the overall portfolio increased to 80.5% at September 30, 2023. This compares to acquired loans as a percentage of total loans of 24.4% and non-acquired loans as a percentage of total loans of 75.6% at December 31, 2022.

Allowance for Credit Losses (“ACL”) on Loans and Certain Off-Balance-Sheet Credit Exposures

​

The ACL reflects management’s estimate of losses that will result from the inability of our borrowers to make required loan payments. The Company records loans charged off against the ACL and subsequent recoveries, if any, increase the ACL when they are recognized. Please see Note 1 — Summary of Significant Accounting Policies, under the “ACL – Loans” section, of our Annual Report on Form 10-K for the year ended December 31, 2022 and Note 2 — Significant Accounting Policies in this Quarterly Report on Form 10-Q for further detailed descriptions of our estimation process and methodology related to the ACL on loans.

​

Management considers forward-looking information in estimating expected credit losses. The Company subscribes to a third-party service which provides a quarterly macroeconomic baseline outlook and alternative scenarios for the United States economy. The baseline, along with the evaluation of alternative scenarios, is used by management to determine the best estimate within the range of expected credit losses. Management evaluates the appropriateness of the reasonable and supportable forecast scenarios and takes into consideration the scenarios in relation to actual economic and other data, such as gross domestic product growth, monetary and fiscal policy, inflation, supply chain issues and global events like the Russian/Ukraine conflict, as well as the volatility and magnitude of changes within those scenarios quarter over quarter, and consideration of conditions within the Bank’s operating environment and geographic area. Additional forecast scenarios may be weighted along with the baseline forecast to arrive at the final reserve estimate. While periods of relative economic stability should generally lead to stability in forecast scenarios and weightings to estimate credit losses, periods of instability can likewise require management to adjust the selection of scenarios and weightings, in accordance with the accounting standards. For the contractual term that extends beyond the reasonable and supportable forecast period, the Company reverts to the long term mean of historical factors within four quarters using a straight-line approach. The Company generally uses a four-quarter forecast and a four-quarter reversion period.

​

In spite of the rapid interest rate hikes experienced cycle-to-date, the U.S. has thus far avoided a recession, although an inverted yield curve such as observed in the current interest rate environment often portends a coming recession. Management continues to use a blended forecast scenario of the baseline, upside, and more severe scenario, depending on the circumstances and economic outlook. For the quarter ending September 30, 2023, management selected a baseline weighting of 50%, a 25% weighting for an upside scenario and a 25% weighting for the more severe scenario. The scenario weightings were unchanged from the second quarter of 2023. The scenario weightings reflect continued recognition of downside risks in the economic forecast from persistent levels of inflation, rising interest rates, and tightening credit conditions conducive of a mild recession. While employment figures still showed resilience and actual loan losses remain at low levels, continued downward shifts in the forecasted commercial real estate price index elevated modeled expected losses for the Commercial Real Estate and Commercial Construction and Land Development, which excludes Residential Construction, loan segments. The resulting provision was approximately $32.7 million during the third quarter of 2023.

​

Longstanding TDR accounting rules were replaced with ASU No. 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (See Note 3 — Recent Accounting and Regulatory Pronouncements). The Company adopted the retirement of TDR guidance, effective January 1, 2023. Please see Note 2 — Summary of Significant Accounting Policies in this Quarterly Report on Form 10-Q for further detailed descriptions of how we determine expected losses from modifications of receivables to borrowers experiencing financial difficulty.

Atlantic Capital was acquired and merged with and into the Bank on March 1, 2022, requiring that a closing date ACL be prepared for Atlantic Capital on a standalone basis and that the acquired portfolio be included in the Bank’s first quarter ACL. Atlantic Capital’s loans represented approximately 8% of the total Bank’s portfolio at March 31, 2022. Given the relative size and complexity of the acquired portfolio, similarities of the loan characteristics, and similar loss history to the existing portfolio, reserve calculations were performed using the Bank's existing CECL model, loan segmentation, and forecast weighting as the first quarter end reserve. As a result of the merger with Atlantic Capital on March 1, 2022, the Company identified approximately $137.9 million of loans as PCD. The acquisition date ACL totaled $27.5 million, consisting of a non-PCD pooled reserve of $13.7 million, PCD pooled reserve of $5.7 million, and PCD individually evaluated reserve of $8.1 million. It represented about 8% of the combined Bank’s ACL reserve at March 31, 2022. The acquisition date reserve for unfunded commitments totaled $3.4 million, or 11% of the combined Bank’s total at March 31, 2022.

The Company has a variety of assets that have a component that qualifies as an off-balance sheet exposure. These primarily include undrawn portions of revolving lines of credit and standby letters of credit. Please see MD&A, under the “Financial Condition”, “Allowance for Credit Losses (“ACL”)” section, of our Annual Report on Form 10-K for the year ended December 31, 2022 and Note 2 — Summary of Significant Accounting Policies in this Quarterly Report on Form 10-Q for further detailed descriptions of our estimation process and methodology related to the ACL on certain off-balance-sheet credit exposures.

​

As of September 30, 2023, the balance of the ACL was $448.0 million or 1.40% of total loans. The ACL increased $20.6 million from the balance of $427.4 million recorded at June 30, 2023. This increase during the third quarter of 2023 included $33.8 million of provision for credit losses, in addition to $13.2 million in net charge-offs. During the first nine months of 2023, the Company recorded $109.1 million of provision for credit losses along with net charge-offs of $17.5 million. The increase in net charge-offs during the third quarter of 2023 was due to one commercial and industrial loan relationship where we charged off $11.6 million. During the three and nine months ended September 30, 2023, the Company recorded a provision for credit losses based on loan growth and continued uncertainty around economic recessionary risks.

​

At September 30, 2023, the Company had a reserve on unfunded commitments of $62.3 million, which was recorded as a liability on the Balance Sheet, compared to $63.4 million at June 30, 2023 and $67.2 million at December 31, 2022. During the three and nine months ended September 30, 2023, the Company recorded a decrease in the reserve for unfunded commitments of $1.1 million and $4.9 million, respectively. For the prior comparative period, the Company recorded a provision for credit losses on unfunded commitments of $20.5 million and $22.5 million, respectively, during three and nine months ended September 30, 2022. The year-to-date provision in 2022 of $22.5 million included the initial provision for credit losses for unfunded commitments acquired from Atlantic Capital, which the Company recorded during the first quarter of 2022. The Company did not have an allowance for credit losses or record a provision for credit losses on investment securities or other financial asset during the first nine months of 2023.

​

The ACL provides 2.70 times coverage of nonperforming loans at September 30, 2023. Net charge-offs to total average loans during three and nine months ended September 30, 2023 were 0.16% and 0.08%, respectively, compared to net recoveries of (0.02)% and net charge-offs of 0.02%, respectively, during the three and nine months ended September 30, 2022. We continued to show solid and stable asset quality numbers and ratios as of September 30, 2023.

| (3) | Includes nonaccrual loans that are purchase credit deteriorated (PCD loans).

| (4) | Loan data excludes mortgage loans held for sale.

| (5) | For purposes of this calculation, total assets include all assets (both acquired and non-acquired).

| (6) | Excludes non-acquired bank premises held for sale of $11.8 million, $10.0 million, $13.3 million, $14.3 million, and $21.2 million as of September 30, 2023, June 30, 2023, March 31, 2023, December 31, 2022, and September 30, 2022, respectively, that is now separately disclosed on the balance sheet.

| (7) | Excludes acquired bank premises held for sale of $3.4 million, $3.4 million, $3.4 million, $3.4 million, and $3.9 million as of September 30, 2023, June 30, 2023, March 31, 2023, December 31, 2022, and September 30, 2022, respectively, that is now separately disclosed on the balance sheet.

Total nonperforming assets were $166.8 million, or 0.52% of total loans and repossessed assets, at September 30, 2023, an increase of $57.0 million, or 51.9%, from December 31, 2022. Total nonperforming loans were $165.9 million, or 0.52%, of total loans, at September 30, 2023, an increase of $57.3 million, or 52.8%, from December 31, 2022. Non-acquired nonperforming loans increased by $59.6 million from December 31, 2022. The increase in non-acquired nonperforming loans was driven primarily by an increase in commercial nonaccrual loans of $57.1 million, an increase in consumer nonaccrual loans of $8.0 million, offset by a decrease in accruing loans past due 90 days or more of $1.6 million and restructured nonaccrual loans of $3.9 million. The increase in commercial nonaccrual loans at September 30, 2023, from December 31, 2022, was primarily due to five commercial and industrial relationships totaling $47.1 million, one commercial and industrial loan totaling $2.3 million, three commercial owner occupied real estate loans totaling $4.9 million and one commercial non owner occupied loan totaling $3.3 million. Acquired nonperforming loans decreased $2.3 million from December 31, 2022. The decrease in the acquired nonperforming loan balances was due to a decrease in consumer nonaccrual loans of $4.8 million, a decrease in restructured nonaccrual loans of $3.8 million, offset by an increase in commercial nonaccrual loans of $6.4 million. The decline in restructured nonaccrual loans over both the nonacquired and acquired loan portfolios was due to the adoption of ASU 2022-02 effective January 1, 2023, which extinguishes the former troubled debt restructuring (TDR) guidance and issues new requirements for determining modified loans to borrowers experiencing financial difficulty.

Interest-Bearing Liabilities

​

Interest-bearing liabilities include interest-bearing transaction accounts, savings deposits, CDs, other time deposits, federal funds purchased, securities sold under agreements to repurchase and other borrowings. Interest-bearing transaction accounts include NOW, HSA, Interest on Layers’ Trust Accounts (“IOLTA”), and Market Rate checking accounts.

Total interest-bearing deposits increased $2.6 billion or 15.0% annualized to $25.8 billion at September 30, 2023 from $23.2 billion at December 31, 2022. This increase was driven by growth in money market account of $2.4 billion, including $1.1 billion in reciprocal insured money market deposits and time deposits of $2.0 billion, including an increase in brokered time deposits of $908.9 million. During the nine months ended September 30, 2023, core deposits decreased $1.4 billion. These funds exclude certificates of deposits and other time deposits and are normally lower cost funds. Core deposits declined as customers moved their funds into higher yielding time deposits as interest rates have risen along with some business customers moving funds for deposit insurance purposes. Federal funds purchased related to the Correspondent Banking Division and repurchase agreements were $513.3 million at September 30, 2023, a $43.1 million decline from December 31, 2022. The Company had no other borrowings outstanding at September 30, 2023 or December 31, 2022. The Company paid off the $400.0 million in FHLB borrowings outstanding at June 30, 2023 as pressure on liquidity subsided from the first and second quarter of 2023. Corporate and subordinated debentures declined by $278,000 to $392.0 million. Some key highlights are outlined below:

| ● | The increase in interest-bearing deposits from December 31, 2022 was driven by an increase in time deposits of $2.0 billion, including an increase in brokered time deposits of $908.9 million and an increase in money market accounts of $2.4 billion, including $1.1 billion in reciprocal insured money market deposits. These increases were partially offset by declines in interest-bearing checking deposits of $1.1 billion and savings deposits of $704.2 million. As customers moved funds from interest-bearing checking and savings accounts, seeking higher yields in the rising rate environment, the Company increased its balance in brokered time deposits and in-market time deposits along with higher yielding money market accounts during the first nine months of 2023. The Company raised interest rates on most interest-bearing deposit products (in particular money market accounts and time deposit specials) during 2023 due to competitive pressures to retain deposits. Average interest-bearing deposits increased $1.8 million to $25.6 billion during the quarter ended September 30, 2023 compared to the same period in 2022. For more information on the composition of our total deposits, see Note 10 – Deposits in this Quarterly Report on Form 10-Q.

| ● | Other borrowings, consisting of FHLB borrowings, decreased $400.0 million during the three months period ended September 30, 2023. The Company borrowed funds from the FHLB to provide excess liquidity in the first and second quarter of 2023. The Company paid down $400 million, on a net basis, in FHLB borrowing during the third quarter of 2023 from $400 million at June 30, 2023 as the financial markets stabilized and the stress on liquidity declined.

Noninterest-Bearing Deposits

​

Noninterest-bearing deposits are transaction accounts that provide our Bank with “interest-free” sources of funds. At September 30, 2023, the period end balance of noninterest-bearing deposits was $11.2 billion compared to $13.2 billion at December 31, 2022. Average noninterest-bearing deposits were $11.4 billion for the third quarter of 2023 compared to $13.9 billion for the third quarter of 2022. The decrease in period end and average noninterest bearing deposits was mainly due to customers seeking higher yields in the rising rate environment. Also, customers have less excess cash as funds from government support programs related to the COVID-19 pandemic decline and due to the effects of higher costs related to inflation.

Uninsured Deposits

At September 30, 2023 and December 31, 2022, the Company had approximately $13.0 billion and $14.6 billion, respectively, in estimated uninsured deposits. The amounts above are estimates and are based on the same methodologies and assumptions used for the Bank’s regulatory reporting requirements issued by the FDIC for the FFIEC 041, also referred to as the Call Report.

Capital Resources

​

Our ongoing capital requirements have been met primarily through retained earnings, less the payment of cash dividends. As of September 30, 2023, shareholders’ equity was $5.2 billion, an increase of $156.1 million, or 3.1%, from December 31, 2022.

In January 2021, the Board of Directors of the Company approved the 2021 Stock Repurchase Plan, which authorized the Company to repurchase 3,500,000 common shares. During the first quarter of 2022, we repurchased 1,012,038 shares, at an average price of $85.43 per share (excluding cost of commissions) for a total of $86.5 million under the 2021 Stock Repurchase Plan.

In April 2022, the Company’s Board of Directors approved a new stock repurchase program (“2022 Stock Repurchase Program”) authorizing the Company to repurchase up to 3,750,000 of the Company’s common shares along with the remaining authorized shares of 370,021 from the 2021 Stock Repurchase Program for a total authorization of 4,120,021 shares. The Company did not repurchase any shares through the 2022 Stock Repurchase Program during 2023 or 2022. The number of shares to be purchased and the timing of the purchases are based on a variety of factors, including, but not limited to, the level of cash balances, general business conditions, regulatory requirements, the market price of our common stock, and the availability of alternative investment opportunities.

We are subject to regulations with respect to certain risk-based capital ratios. These risk-based capital ratios measure the relationship of capital to a combination of balance sheet and off-balance sheet risks. The values of both balance sheet and off-balance sheet items are adjusted based on the rules to reflect categorical credit risk. In addition to the risk-based capital ratios, the regulatory agencies have also established a leverage ratio for assessing capital adequacy. The leverage ratio is equal to Tier 1 capital divided by total consolidated on-balance sheet assets (minus amounts deducted from Tier 1 capital). The leverage ratio does not involve assigning risk weights to assets.

​

Specifically, we are required to maintain the following minimum capital ratios:

| ● | a CET1, risk-based capital ratio of 4.5%;

| ● | a Tier 1 risk-based capital ratio of 6%;

| ● | a total risk-based capital ratio of 8%; and

| ● | a leverage ratio of 4%.

Under the current capital rules, Tier 1 capital includes two components: CET1 capital and additional Tier 1 capital. The highest form of capital, CET1 capital, consists solely of common stock (plus related surplus), retained earnings, accumulated other comprehensive income, otherwise referred to as AOCI, and limited amounts of minority interests that are in the form of common stock. Additional Tier 1 capital is primarily comprised of noncumulative perpetual preferred stock and Tier 1 minority interests. Tier 2 capital generally includes the allowance for loan losses up to 1.25% of risk-weighted assets, qualifying preferred stock, subordinated debt, trust preferred securities and qualifying tier 2 minority interests, less any deductions in Tier 2 instruments of an unconsolidated financial institution. AOCI is presumptively included in CET1 capital and often would operate to reduce this category of capital. When the current capital rules were first implemented, the Bank exercised its one-time opportunity at the end of the first quarter of 2015 for covered banking organizations to opt out of much of this treatment of AOCI, allowing us to retain our pre-existing treatment for AOCI.

In order to avoid restrictions on capital distributions or discretionary bonus payments to executives, a banking organization must maintain a “capital conservation buffer” on top of its minimum risk-based capital requirements. This buffer must consist solely of Tier 1 Common Equity, but the buffer applies to all three risk-based measurements (CET1, Tier 1 capital and total capital), resulting in the following effective minimum capital plus capital conservation buffer ratios: (i) a CET1 capital ratio of 7.0%, (ii) a Tier 1 risk-based capital ratio of 8.5%, and (iii) a total risk-based capital ratio of 10.5%.

The Bank is also subject to the regulatory framework for prompt corrective action, which identifies five capital categories for insured depository institutions (well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized) and is based on specified thresholds for each of the three risk-based regulatory capital ratios (CET1, Tier 1 capital and total capital) and for the leverage ratio.

​

The federal banking agencies revised their regulatory capital rules to (i) address the implementation of CECL; (ii) provide an optional three-year phase-in period for the adoption date adverse regulatory capital effects that banking organizations are expected to experience upon adopting CECL; and (iii) require the use of CECL in stress tests beginning with the 2020 capital planning and stress testing cycle for certain banking organizations that are subject to stress testing. CECL became effective for us on January 1, 2020 and the Company applied the provisions of the standard using the modified retrospective method as a cumulative-effect adjustment to retained earnings. Related to the implementation of ASU 2016-13, we recorded additional allowance for credit losses for loans of $54.4 million, deferred tax assets of $12.6 million, an additional reserve for unfunded commitments of $6.4 million and an adjustment to retained earnings of $44.8 million. Instead of recognizing the effects on regulatory capital from ASU 2016-13 at adoption, the Company initially elected the option for recognizing the adoption date effects on the Company’s regulatory capital calculations over a three-year phase-in.

​

In response to the COVID-19 pandemic in 2020, the federal banking agencies issued a final rule for additional transitional relief to regulatory capital related to the impact of the adoption of CECL. The Company chose the five-year transition method and is deferring the recognition of the effects from the adoption date and the CECL difference for the first two years of application. The modified CECL transitional amount was fixed as of December 31, 2021, and that amount began the three-year phase out in the first quarter of 2022 with 50% being phased out in 2023.

​

The well-capitalized minimums and the Company’s and the Bank’s regulatory capital ratios for the following periods are reflected below:

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Well-Capitalized | ​ | ​ | September 30, | ​ | ​ | December 31, | ​
​ | ​ | Minimums | ​ | ​ | 2023 | ​ | ​ | 2022 | ​
SouthState Corporation: | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Common equity Tier 1 risk-based capital | ​ | N/A | ​ | ​ | 11.47 | % | ​ | 10.96 | %
Tier 1 risk-based capital |  | 6.00 | % |  | 11.47 | % |  | 10.96 | %
Total risk-based capital | ​ | 10.00 | % | ​ | 13.76 | % | ​ | 12.97 | %
Tier 1 leverage | ​ | N/A | ​ | ​ | 9.34 | % | ​ | 8.72 | %
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
SouthState Bank: | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Common equity Tier 1 risk-based capital | ​ | 6.50 | % | ​ | 12.25 | % | ​ | 11.80 | %
Tier 1 risk-based capital | ​ | 8.00 | % | ​ | 12.25 | % | ​ | 11.80 | %
Total risk-based capital | ​ | 10.00 | % | ​ | 13.44 | % | ​ | 12.69 | %
Tier 1 leverage | ​ | 5.00 | % | ​ | 9.96 | % | ​ | 9.39 | %

The Company’s and Bank’s Common equity Tier 1 risk-based capital, Tier 1 risk-based capital and total risk-based capital and Tier 1 leverage ratios all increased compared to December 31, 2022. These ratios increased mainly due to net income during 2023 of $387.5 million. Tier 1 capital increased 7.9% and 7.0% at both the Company and Bank, respectively, with the increase in equity resulting from the net income recognized during the current period. Total risk-based capital increased 9.4% and 9.3% at both the Company and Bank, respectively, with the increase in equity resulting from the net income recognized during the current period, along with the increase in the allowance for credit losses and unfunded commitments includable in Tier 2 capital. Both regulatory risk-based assets and quarterly average assets remained reasonably flat compared to the fourth quarter with average assets for the Company and Bank increasing 0.8% and risk-based assets increasing 3.1%. Our capital ratios are currently well in excess of the minimum standards and continue to be in the “well capitalized” regulatory classification. Should the Company need to sell its available for sale and held to maturity securities for liquidity purposes and recognize the unrealized losses as of September 30, 2023 through earnings, all else equal, our capital ratios would remain well in excess of the minimum standards and continue to be in the “well capitalized” regulatory classification.

Liquidity

​

Liquidity refers to our ability to generate sufficient cash to meet our financial obligations, which arise primarily from the withdrawal of deposits, extension of credit and payment of operating expenses. Liquidity risk is the risk that the Bank’s financial condition or overall safety and soundness is adversely affected by an inability (or perceived inability) to meet its obligations. Our Asset Liability Management Committee (“ALCO”) is charged with the responsibility of monitoring policies designed to ensure acceptable composition of our asset/liability mix. Two critical areas of focus for ALCO are interest rate sensitivity and liquidity risk management. We have employed our funds in a manner to provide liquidity from both assets and liabilities sufficient to meet our cash needs.

​

Asset liquidity is maintained by the maturity structure of loans, investment securities and other short-term investments. Management has policies and procedures governing the length of time to maturity on loans and investments. Normally, changes in the earning asset mix are of a longer-term nature and are not used for day-to-day corporate liquidity needs.

Our liabilities provide liquidity on a day-to-day basis. Daily liquidity needs are met from deposit levels or from our use of federal funds purchased, securities sold under agreements to repurchase, interest-bearing deposits at other banks and other short-term borrowings. We engage in routine activities to retain deposits intended to enhance our liquidity position. These routine activities include various measures, such as the following:

​

| ● | Emphasizing relationship banking to new and existing customers, where borrowers are encouraged and normally expected to maintain deposit accounts with our Bank;

| ● | Pricing deposits, including certificates of deposit, at rate levels that will attract and /or retain balances of deposits that will enhance our Bank’s asset/liability management and net interest margin requirements; and

| ● | Continually working to identify and introduce new products that will attract customers or enhance our Bank’s appeal as a primary provider of financial services.

Our non-acquired loan portfolio increased by approximately $3.0 billion, or approximately 17.4% annualized, compared to the balance at December 31, 2022. The increase from December 31, 2022 was mainly related to organic growth and renewals on acquired loans. The acquired loan portfolio decreased by $1.1 billion from the balance at December 31, 2022 through principal paydowns, charge-offs, foreclosures and renewals of acquired loans.

Our investment securities portfolio (excluding trading securities) decreased $845.3 million compared to the balance at December 31, 2022. The decrease in investment securities from December 31, 2022 was a result of maturities, calls, sales and paydowns of investment securities totaling $861.6 million, a reduction from the net amortization of premiums of $15.2 million, and a decrease in the market value of the available for sale investment securities portfolio of $196.3 million. This decrease was partially offset by purchases of available for sale investment securities totaling $34.5 million and other investment securities of $193.3 million. There were no purchases of held to maturity securities during the quarter. Total cash and cash equivalents were $1.3 billion at September 30, 2023 as compared to $1.3 billion at December 31, 2022. While the Company has increased its use of brokered deposits since December 31, 2022, the ratio of brokered deposits to total deposits at September 30, 2023 was 2.9% compared to the Company’s internal limit of 15%. During 2023, the Company has borrowed funds from the FHLB on a short-term basis, however there were no outstanding borrowings from the FHLB at September 30, 2023.

At September 30, 2023 and December 31, 2022, we had $1.1 billion and $150.0 million of traditional, out–of-market brokered deposits, respectively. At September 30, 2023 and December 31, 2022, we had $2.0 billion and $637.0 million, respectively, of reciprocal deposits. Total deposits were $36.9 billion at September 30, 2023, an increase of $584.6 million from $36.4 billion at December 31, 2022. This increase was driven by growth in money market accounts of $2.4 million, including $1.1 billion in reciprocal insured money market deposits and time deposits of $2.0 billion, including an increase in brokered time deposits of $908.9 million. These increases were offset by d eclines in noninterest-bearing, interest-bearing checking and savings accounts of $2.0 billion, $1.1 billion and $704.2 million, respectively. As customers moved funds from noninterest bearing checking, interest bearing checking and savings accounts, seeking higher yields in the rising rate environment along with insurance coverage, the Company’s balance in higher costing in-market time deposits and brokered time deposits and in money market deposit accounts including reciprocal insured money market accounts has increased. The Company raised interest rates on most interest-bearing deposit products (in particular time deposit specials and money market accounts) during 2023 due to competitive pressures to retain deposits. Total corporate and subordinated debentures and other borrowings at September 30, 2023 were $392.0 million and consisted of trust preferred securities and subordinated debentures. The Company had other borrowings consisting of FHLB borrowings during 2023 to increase liquidity but has since repaid in full the FHLB borrowings as of September 30, 2023 as the financial markets stabilized and the stress on liquidity declined. Total short-term borrowings at September 30, 2023 were $513.3 million, consisting of $253.5 million in federal funds purchased and $259.8 million in securities sold under agreements to repurchase. To the extent that we employ other types of non-deposit funding sources, typically to accommodate retail and correspondent customers, we continue to take in shorter maturities of such funds. Our current approach may provide an opportunity to sustain a low funding rate or possibly lower our cost of funds but could also increase our cost of funds if interest rates rise.

​

Through the operations of our Bank, we have made contractual commitments to extend credit in the ordinary course of our business activities. These commitments are legally binding agreements to lend money to our customers at predetermined interest rates for a specified period of time. We manage the credit risk on these commitments by subjecting them to normal underwriting and risk management processes. We believe that we have adequate sources of liquidity to fund commitments that are drawn upon by the borrowers. In addition to commitments to extend credit, we also issue standby letters of credit, which are assurances to third parties that they will not suffer a loss if our customer fails to meet its contractual obligation to the third-party. Although our experience indicates that many of these standby letters of credit will expire unused, through our various sources of liquidity, we believe that we will have the resources to meet these obligations should the need arise.

​

Our ongoing philosophy is to remain in a liquid position, as reflected by such indicators as the composition of our earning assets, typically including some level of reverse repurchase agreements; federal funds sold; balances at the Federal Reserve Bank; and/or other short-term investments; asset quality; well-capitalized position; and profitable operating results. Cyclical and other economic trends and conditions can disrupt our desired liquidity position at any time. We expect that these conditions would generally be of a short-term nature. Under such circumstances, we expect our reverse repurchase agreements and federal funds sold positions, or balances at the Federal Reserve Bank, if any, to serve as the primary source of immediate liquidity. We could draw on additional alternative immediate funding sources from lines of credit extended to us from our correspondent banks. The Bank may also access funds from borrowing facilities established with the Federal Home Loan Bank of Atlanta and the discount window of the Federal Reserve Bank of Atlanta. The Bank may also access funds through the Federal Reserve Bank Term Funding Program. At September 30, 2023, our Bank had a total FHLB credit facility of $7.8 billion, with $2.1 million FHLB letters of credit outstanding at quarter-end, leaving $7.8 billion in availability on the FHLB credit facility. At September 30, 2023, our Bank had $1.9 billion of credit available at the Federal Reserve Bank’s discount window and federal funds credit lines of $300.0 million with no balances outstanding at quarter-end. The Bank also has an internal limit on brokered deposits of 15% of total deposits which would allow capacity of $5.5 billion at September 30, 2023. The Bank had $1.1 billion of outstanding brokered deposits at the end of the quarter leaving $4.4 billion in available capacity. All of these resources would provide an additional $14.4 billion in funding if we needed additional liquidity. The Bank also has $3.7 billion in market value of unpledged securities at September 30, 2023 that can be pledged to attain additional funds if necessary. We can also consider actions such as deposit promotions to increase core deposits. The Company has a $100.0 million unsecured line of credit with U.S. Bank National Association with no balance outstanding at September 30, 2023. We believe that our liquidity position continues to be adequate and readily available.

Our contingency funding plan describes several potential stages based on stressed liquidity levels. Liquidity key risk indicators are reported to the Board of Directors on a quarterly basis. We maintain various wholesale sources of funding. If our deposit retention efforts were to be unsuccessful, we would use these alternative sources of funding. Under such circumstances, depending on the external source of funds, our interest cost would vary based on the range of interest rates charged. This could increase our cost of funds, impacting our net interest margin and net interest spread.

Asset-Liability Management and Market Risk Sensitivity

​

Our earnings and the economic value of equity vary in relation to the behavior of interest rates and the accompanying fluctuations in market prices of certain of our financial instruments. We define interest rate risk as the risk to earnings and equity arising from the behavior of interest rates. These behaviors include increases and decreases in interest rates as well as continuation of the current interest rate environment.

​

Our interest rate risk principally consists of reprice, option, basis, and yield curve risk. Reprice risk results from differences in the maturity or repricing characteristics of asset and liability portfolios. Option risk arises from embedded options in the investment and loan portfolios such as investment securities calls and loan prepayment options. Option risk also exists since deposit customers may withdraw funds at their discretion in response to general market conditions, competitive alternatives to existing accounts or other factors. The exercise of such options may result in higher costs or lower revenue. Basis risk refers to the potential for changes in the underlying relationship between market rates or indices, which subsequently result in narrowing spreads on interest-earning assets and interest-bearing liabilities. Basis risk also exists in administered rate liabilities, such as interest-bearing checking accounts, savings accounts, and money market accounts where the price sensitivity of such products may vary relative to general markets rates. Yield curve risk refers to adverse consequences of nonparallel shifts in the yield curves of various market indices that impact our assets and liabilities.

​

We use simulation analysis as a primary method to assess earnings at risk and equity at risk due to assumed changes in interest rates. Management uses the results of its various simulation analyses in combination with other data and observations to formulate strategies designed to maintain interest rate risk within risk tolerances.

​

Simulation analysis involves the use of several assumptions including, but not limited to, the timing of cash flows such as the terms of contractual agreements, investment security calls, loan prepayment speeds, deposit attrition rates, the interest rate sensitivity of loans and deposits relative to general market rates, and the behavior of interest rates and spreads. Equity at risk simulation uses assumptions regarding discount rates that value cash flows. Simulation analysis is highly dependent on model assumptions that may vary from actual outcomes. Key simulation assumptions are subject to sensitivity analysis to assess the impact of assumption changes on earnings at risk and equity at risk. Model assumptions are reviewed by our Assumptions Committee.

Earnings at risk is defined as the percentage change in net interest income due to assumed changes in interest rates. Earnings at risk is generally used to assess interest rate risk over relatively short time horizons.

Equity at risk is defined as the percentage change in the net economic value of assets and liabilities due to changes in interest rates compared to a base net economic value. The discounted present value of all cash flows represents our economic value of equity. Equity at risk is generally considered a measure of the long-term interest rate exposures of the balance sheet at a point in time.

The earnings simulation models take into account our contractual agreements with regard to investments, loans, deposits, borrowings, and derivatives as well as a number of behavioral assumptions applied to certain assets and liabilities.

Mortgage banking derivatives used in the ordinary course of business consist of forward sales contracts and interest rate lock commitments on residential mortgage loans. These derivatives involve underlying items, such as interest rates, and are designed to mitigate risk. Derivatives are also used to hedge mortgage servicing rights. For additional information see Note 28—Derivative Financial Instruments in the consolidated financial statements.

​

From time to time, we execute interest rate swaps to hedge some of our interest rate risks. Under these arrangements, the Company enters into a variable rate loan with a client in addition to a swap agreement. The swap agreement effectively converts the client’s variable rate loan into a fixed rate loan. The Company then enters into a matching swap agreement with a third-party dealer to offset its exposure on the customer swap. The Company may also execute interest rate swap agreements that are not specific to client loans. As of September 30, 2023, the Company had a series of short-term interest rate hedges to address monthly accrual mismatches related to the Company’s ARC program and its transition from LIBOR to SOFR after June 30, 2023. For additional information on these derivatives refer to Note 28—Derivative Financial Instruments in the consolidated financial statements.

Our interest rate risk key indicators are applied to a static balance sheet using forward rates from the Moody’s Baseline Scenario. The Company will also use other rate forecasts, including, but not limited to, Moody’s Consensus Scenario. This Base Case Scenario assumes the maturity composition of asset and liability rollover volumes is modeled to approximately replicate current consolidated balance sheet characteristics throughout the simulation. These treatments are consistent with the Company’s goal of assessing current interest rate risk embedded in its current balance sheet. The Base Case Scenario assumes that maturing or repricing assets and liabilities are replaced at prices referencing forward rates derived from the selected rate forecast consistent with current balance sheet pricing characteristics. Key rate drivers are used to price assets and liabilities with sensitivity assumptions used to price non-maturity deposits. The sensitivity assumptions for the pricing of non-maturity deposits are subjected to sensitivity analysis no less frequently than on an annual basis.

Interest rate shocks are applied to the Base Case on an instantaneous basis. Our policy establishes the use of upward and downward interest rate shocks applied in 100 basis point increments through 400 basis points. We calculate smaller rate shocks as needed. At times, market conditions may result in assumed rate movements that will be deemphasized. For example, during a period of ultra-low interest rates, certain downward rate shocks may be impractical. The model simulation results produced from the Base Case Scenario and related instantaneous shocks for changes in net interest income and changes in the economic value of equity are referred to as the Core Scenario Analysis and constitute the policy key risk indicators for interest rate risk when compared to risk tolerances.

During the third quarter of 2023, the beta assumption applied to total deposits increased to reflect changes in deposit mix. From the beginning of the upward rate cycle, our deposit costs have increased from five basis points to one hundred fifty-three basis points. During this period, the federal funds rate has increased 525 basis points. Accordingly, our cycle to date beta has been approximately 27%. Management recognizes the difficulty using historical data to forecast deposit betas in the current environment. For internal purposes, we are assuming a cumulative upward rate cycle beta of 34.0% with a terminal federal funds rate of 5.50% and a corresponding cumulative rate increase of 525 basis points.

​

The following interest rate risk metrics are derived from analysis using the Moody’s Consensus Scenario published in October 2023 as the Base Case. As of September 30, 2023, the earnings simulations indicated that the year 1 impact of an instantaneous 100 basis point increase / decrease in rates would result in an estimated 1.3% increase (up 100) and 1.9% decrease (down 100) in net interest income.

​

We use Economic Value of Equity (“EVE”) analysis as an indicator of the extent to which the present value of our capital could change, given potential changes in interest rates. This measure also assumes a static balance sheet (Base Case Scenario) with rate shocks applied as described above. At September 30, 2023, the percentage change in EVE due to a 100-basis point increase or decrease in interest rates was 2.4% decrease and 0.1% increase, respectively. The percentage changes in EVE due to a 200-basis point increase or decrease in interest rates were 5.6% decrease and 0.9% decrease, respectively. The interest rate shock analysis results for EVE sensitivities are unusual as the benefits of repricing assets are mitigated by increasing deposit costs, and downward shocks are constrained on various balance sheet categories due to the inability to price products below floors or zero. This is particularly meaningful given the cost of deposits as of September 30, 2023.

The analysis below reflects a Base Case and shocked scenarios that assume a static balance sheet projection where volume is added to maintain balances consistent with current levels, except for PPP loans that are not assumed to be replaced. Base Case assumes new and repricing volumes reference forward rates derived from the Moody’s Consensus rate forecast. Instantaneous, parallel, and sustained interest rate shocks are applied to the Base Case scenario over a one-year time horizon.

LIBOR Transition

​

The publication of all tenors of U.S. dollar LIBOR on a representative basis ceased as of September 30, 2023. As previously noted, we established a cross-functional LIBOR transition working group that (1) assessed the Company's exposure to LIBOR indexed instruments and the data, systems and processes that were impacted; (2) established a detailed implementation plan; and (3) developed a formal governance structure for the transition. The Company developed and implemented various proactive steps to facilitate the transition on behalf of customers up through September 30, 2023, which included:

​

| ● | The adoption and implementation of fallback provisions that provided for the determination of replacement rates for LIBOR-linked financial products.

| ● | The adoption of new products linked to alternative reference rates, such as adjustable-rate mortgages, consistent with guidance provided by the U.S. regulators, the Alternative Reference Rates Committee, and GSEs.

| ● | The selection of SOFR indices as the replacement indices, and successful completion of systems testing using the SOFR replacement indices.

| ● | Successful transition of Libor-exposed instruments to SOFR and other indices as appropriate for contracts that provided for a specific replacement index other than SOFR.

​

We utilized the provisions of the Adjustable Interest Rate (LIBOR) Act passed by Congress and signed into law by the President in March 2022 for certain contracts referencing LIBOR. The Act provides for the use of SOFR as the replacement index with a spread adjustment when the remaining LIBOR indices are discontinued. The Act applies when there is no contract provision addressing the loss of LIBOR and may be used otherwise as well, provided the contract does not provide for a specific replacement index.

​

In addition, the Company developed and implemented processes to educate client-facing associates and coordinate communications with customers regarding the transition.

​

As of September 30, 2023, the Company’s LIBOR-indexed loans, derivatives, and trust preferred securities have migrated to SOFR and other indices and will reprice by reference to such replacement indices at the next scheduled repricing date. Final validations and other verification tasks have been complete.

Deposit and Loan Concentrations

​

We have no material concentration of deposits from any single customer or group of customers. We have no significant portion of our loans concentrated within a single industry or group of related industries. Furthermore, we attempt to avoid making loans that, in an aggregate amount, exceed 10% of total loans to a multiple number of borrowers engaged in similar business activities. As of September 30, 2023, there were no aggregated loan concentrations of this type. We do not believe there are any material seasonal factors that would have a material adverse effect on us. We do not have any foreign loans or deposits.

Concentration of Credit Risk

​

Each category of earning assets has a certain degree of credit risk. We use various techniques to measure credit risk. Credit risk in the investment portfolio can be measured through bond ratings published by independent agencies. In the investment securities portfolio, the investments consist of U.S. government-sponsored entity securities, tax-free securities, or other securities having ratings of “AAA” to “Not Rated”. All securities, with the exception of those that are not rated, were rated by at least one of the nationally recognized statistical rating organizations. The credit risk of the loan portfolio can be measured by historical experience. We maintain our loan portfolio in accordance with credit policies that we have established. Although the Bank has a diversified loan portfolio, a substantial portion of our borrowers’ abilities to honor their contracts is dependent upon economic conditions within our geographic footprint and the surrounding regions.

We consider concentrations of credit to exist when, pursuant to regulatory guidelines, the amounts loaned to a multiple number of borrowers engaged in similar business activities which would cause them to be similarly impacted by general economic conditions represents 25% of total Tier 1 capital plus regulatory adjusted allowance for credit losses of the Company, or $1.1 billion at September 30, 2023. Based on this criteria, we had eight such credit concentrations at September 30, 2023, including loans to lessors of nonresidential buildings (except mini-warehouses) of $6.9 billion, loans secured by owner occupied office buildings (including medical office buildings) of $1.9 billion, loans secured by owner occupied nonresidential buildings (excluding office buildings) of $1.8 billion, loans to lessors of residential buildings (investment properties and multi-family) of $2.3 billion, loans secured by 1st mortgage 1-4 family owner occupied residential property (including condos and home equity lines) of $8.4 billion, loans secured by jumbo (original loans greater than $548,250) of $2.5 billion, loans secured by business assets including accounts receivable, inventory and equipment of $2.2 billion and loans to consumers secured by non-real estate of $1.2 billion. The risk for these loans and for all loans is managed collectively through the use of credit underwriting practices developed and updated over time. The loss estimate for these loans is determined using our standard ACL methodology.

After the adoption of CECL in the first quarter of 2020, banking regulators established guidelines for calculating credit concentrations. Banking regulators set the guidelines for construction, land development and other land loans to total less than 100% of total Tier 1 capital less modified CECL transitional amount plus ACL (CDL concentration ratio) and for total commercial real estate loans (construction, land development and other land loans along with other non-owner occupied commercial real estate and multifamily loans) to total less than 300% of total Tier 1 capital less modified CECL transitional amount plus ACL (CRE concentration ratio). Both ratios are calculated by dividing certain types of loan balances for each of the two categories by the Bank’s total Tier 1 capital less modified CECL transitional amount plus ACL. At September 30, 2023 and December 31, 2022, the Bank’s CDL concentration ratio was 57.6% and 64.8%, respectively, and its CRE concentration ratio was 240.2% and 249.0%, respectively. As of September 30, 2023, the Bank was below the established regulatory guidelines. When a bank’s ratios are in excess of one or both of these loan concentration ratios guidelines, banking regulators generally require an increased level of monitoring in these lending areas by Bank management. Therefore, we monitor these two ratios as part of our concentration management processes.

R econciliation of GAAP to Non-GAAP

​

The return on average tangible equity is a non-GAAP financial measure that excludes the effect of the average balance of intangible assets and adds back the after-tax amortization of intangibles to GAAP basis net income. Management believes these non-GAAP financial measures provide additional information that is useful to investors in evaluating our performance and capital and may facilitate comparisons with other institutions in the banking industry as well as period-to-period comparisons. Non-GAAP measures should not be considered as an alternative to any measure of performance or financial condition as promulgated under GAAP, and investors should consider the Company’s performance and financial condition as reported under GAAP and all other relevant information when assessing the performance or financial condition of the Company. Non-GAAP measures have limitations as analytical tools, are not audited, and may not be comparable to other similarly titled financial measures used by other companies. Investors should not consider non-GAAP measures in isolation or as a substitute for analysis of the Company’s results or financial condition as reported under GAAP.

For any forward-looking statements made in this report or in any documents incorporated by reference into this Report, we claim the protection of the safe harbor for forward looking statements contained in the Private Securities Litigation Reform Act of 1995. All forward-looking statements speak only as of the date they are made and are based on information available at that time. We do not undertake any obligation to update or otherwise revise any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by federal securities laws. As forward-looking statements involve significant risks and uncertainties, caution should be exercised against placing undue reliance on such statements. All subsequent written and oral forward-looking statements by us or any person acting on our behalf are expressly qualified in their entirety by the cautionary statements contained or referred to in this Report.

​

Item 4. CONTROLS AND PROCEDURES

​

Evaluation of Disclosure Controls and Procedures

​

SouthState’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of SouthState’s disclosure controls and procedures as of September 30, 2023, in accordance with Rule 13a-15 of the Securities Exchange Act of 1934. We applied our judgment in the process of reviewing these controls and procedures, which, by their nature, can provide only reasonable assurance regarding our control objectives. Based upon that evaluation, our Chief Executive Officer and the Chief Financial Officer concluded that SouthState’s disclosure controls and procedures as of September 30, 2023, were effective to provide reasonable assurance regarding our control objectives.

​

The design of any system of controls and procedures is based in part upon certain assumptions about the likelihood of future events. There can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, regardless of how remote.

​

Changes in Internal Control over Financial Reporting

​

There has been no change in our internal control over financial reporting during the three months ended September 30, 2023, that has materially affected, or is likely to materially affect, our internal control over financial reporting.

| (c) | Issuer Purchases of Registered Equity Securities:

In April 2022, the Company’s Board of Directors approved a new stock repurchase program (“2022 Stock Repurchase Program”) authorizing the Company to repurchase up to 3,750,000 of the Company’s common shares along with the remaining authorized shares of 370,021 from the 2021 Stock Repurchase Program for a total authorization of 4,120,021 shares. The Company did not repurchase any shares through the 2022 Stock Repurchase Program during 2022 or 2023. Of the 4,120,021 shares authorized under the 2022 Stock Repurchase Program, we may repurchase up to 4,120,021 shares of common stock. The number of shares to be purchased and the timing of the purchases are based on a variety of factors, including, but not limited to, the level of cash balances, general business conditions, regulatory requirements, the market price of our common stock, and the availability of alternative investment opportunities.

​

The following table reflects share repurchase activity during the third quarter of 2023:
