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 months ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024.

​

The consolidated balance sheet at December 31, 2023 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, 2023, as filed with the Securities and Exchange Commission (the “SEC”) on March 4, 2024, 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 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 securities 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 the 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, 2023. As of March 31, 2024 and December 31, 2023, the Company had $2.4 billion and $2.5 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 March 31, 2024 and December 31, 2023, the accrued interest receivables for all investment securities recorded in Other Assets were $25.8 million and $26.5 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 the 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, 2023.

​

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. 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.

​

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.

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 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 March 31, 2024 and December 31, 2023, the accrued interest receivables for loans recorded in Other Assets were $131.0 million and $127.0 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 March 31, 2024 and December 31, 2023, the liabilities recorded for expected credit losses on unfunded commitments were $53.2 million and $56.3 million, respectively. The current adjustment to the reserve for unfunded commitments is recognized through the Provision for Credit Losses in the Consolidated Statements of Income.

Reclassification and Correction

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.

Note 3 — Recent Accounting and Regulatory Pronouncements

Accounting Standards Adopted

In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. The amendments in this update allow the option for an entity to apply the proportional amortization method of accounting to other equity investments, in addition to the previously permitted low-income housing tax credit (“LIHTC”) structured investments, that are made for the primary purpose of receiving tax credits or other income tax benefits, if certain conditions are met. The proportional amortization method of accounting results in the amortization of applicable investments, as well as the related income tax credits or other income tax benefits received, being presented on a single line within income tax expense on the consolidated statements of income. Prior to this update, the application of the proportional amortization method of accounting was limited to LIHTC structured investments. Under this update, an entity has the option to apply the proportional amortization method of accounting to applicable investments on a tax-credit-program-by-tax-credit-program basis. Also under this update, LIHTC structured investments for which the proportional amortization method is not applied can no longer be accounted for using the delayed equity contribution guidance. The amendments in this update also require additional disclosures in interim and annual periods concerning investments for which the proportional amortization method is applied, including the nature of tax equity investments, the effect of tax equity investments and related income tax credits and other income tax benefits on the financial position and results of operations.

Table of Contents

The Company adopted ASU 2023-02 effective January 1, 2024, and changed the accounting method of its LIHTC structured investments from the equity method to the proportional amortization method. The Company adopted ASU 2023-02 using the modified retrospective approach. Under this adoption approach, management was required to verify the LIHTCs met the conditions for proportional amortization method as of the date the investments were originally made by the Bank. In addition, management evaluated the actual tax credits and other income tax benefits received, as well as the remaining benefits expected to be received, as of the adoption date. The cumulative difference between the equity method and proportional amortization method resulted in a one-time cumulative effect adjustment recorded through retained earnings as of January 1, 2024. The cumulative effect resulting from the adoption of proportional amortization method was a net reduction to retained earnings of $9.4 million, which reflects the amortization expense in proportion to the tax credits and benefits realized on a life-to-date basis of all LIHTCs as of December 31, 2023. Additionally, the proportional amortization method does not require deferred taxes be tracked as was the case with the equity method; therefore, deferred taxes of $836,000 were written-off as an additional reduction to retained earnings effective January 1, 2024.

Issued But Not Yet Adopted Accounting Standards

In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, to improve disclosures about a public entity’s reportable segments and address requests from investors and other allocators of capital for additional, more detailed information about a reportable segment’s expenses. Segment information gives investors an understanding of overall performance and is key to assessing potential future cash flows. In addition, although information about a segment’s revenue and measure of profit or loss is disclosed in an entity’s financial statements, there is limited information disclosed about a segment’s expenses. The key amendments include annual and interim disclosures of significant expenses and other segment items that are regularly provided to the chief operating decision maker and included within each reported measure of profit or loss, as well as any other key measure of performance used for segment management decisions. This ASU also requires disclosure of key profitability measures used in assessing performance and how to allocate resources. The amendments in this ASU are effective for fiscal years beginning after December 15, 2023, and for interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company does not anticipate this ASU will have a material impact on its financial statements.

​

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which aims to address requests for improved income tax disclosures from investors, lenders, creditors and other allocators of capital (collectively, “investors”) that use the financial statements to make capital allocation decisions. The amendments in this ASU address investor requests for more transparency about income tax information, including jurisdictional information, by requiring consistent categories and greater disaggregation of information in both the rate reconciliation and income taxes paid disaggregated by jurisdiction. The amendments are effective for annual periods beginning after December 15, 2024. The Company does not anticipate this ASU will have a material impact on its financial statements.

The Company’s 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 March 31, 2024, we determined that there was no impairment on other investment securities.

The amortized cost and fair value of debt securities at March 31, 2024 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 valuation methodology for securities impairment is disclosed in Note 1—Summary of Significant Accounting Policies, under “Investment Securities” section, of our Annual Report on Form 10-K for the year ended December 31, 2023. All debt securities in an unrealized loss position as of March 31, 2024 continue to perform as scheduled and management does not believe there is a credit loss or a provision for credit losses is necessary. Management does not currently intend to sell the securities within the portfolio and it is not more-likely-than-not that the Company will be required to sell the debt securities. Management continues to monitor all of the securities with a high degree of scrutiny. See Note 2 — Summary of Significant Accounting Policies for further discussion.

| (1) | Construction and land development includes loans for both commercial construction and development, as well as loans for 1-4 family residential construction and lot loans.

| (2) | Consumer owner occupied real estate includes loans on both 1-4 family owner occupied property, as well as loans collateralized by 1-4 family owner occupied properties with a business intent.

The above table reflects the loan portfolio at the amortized cost basis for the periods March 31, 2024 and December 31, 2023, to include net deferred costs of $73.5 million and $68.0 million, respectively, and unamortized discount total related to loans acquired of $47.0 million and $51.3 million, respectively. Accrued interest receivables of $131.0 million and $127.0 million, respectively, are accounted for separately and reported in other assets for the periods March 31, 2024 and December 31, 2023.

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 of 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, are still an 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 Bank’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 properties 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 the 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 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 decreased $9.0 million during the three months ended March 31, 2024.

​

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). See Note 2 — Summary of Significant Accounting Policies for how such modifications are factored into the determination of the ACL for the periods presented above.

​

The following tables present loans designated as modifications made to borrowers experiencing financial difficulty during the three months ended March 31, 2024 and 2023, respectively. The loans are segregated by type of modification and asset class, indicating the financial effect of the modifications. The amortized cost balance for the modified loans presented below exclude accrued interest receivable of approximately $16,000 and $12,000 as of March 31, 2024 and 2023, respectively.

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 March 31, 2024, the Company had no remaining commitments to lend additional funds on loans to borrowers experiencing financial difficulty and modified during the current reporting period.

Note 7 — Leases

As of March 31, 2024 and December 31, 2023, we had operating right-of-use (“ROU”) assets of $99.7 million and $100.3 million, respectively, and operating lease liabilities of $107.7 million and $108.3 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 20 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 rate 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.

As of March 31, 2024, the Company held a small number of finance leases assumed in connection to the CenterState merger completed in 2020. These leases are all real estate leases. Terms and conditions are similar to those real estate operating leases described above. Lease classifications from the acquired institutions were retained. At March 31, 2024, 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 March 31, 2024, we had no additional operating leases that have not yet commenced.

Equipment Lessor

SouthState has an Equipment Finance Group which goes to market through intermediaries. The Equipment Finance Group is primarily focused on serving the construction and utility segments. Lease terms typically range from 24 months to 120 months. At the end of the lease term, the lessee has the option to renew the lease, return the equipment, or purchase the equipment. In the event the equipment is returned, there is a remarketing agreement with the intermediary to sell the equipment. The Equipment Finance Group offers the following lease products: TRAC Leases, Split-TRAC Leases, and FMV Leases. Direct finance equipment leases are included in commercial and industrial loans on the Consolidated Balance Sheets.

​

The estimated residual values for direct finance leases are established by approved intermediary who utilizes internally developed analyses, external studies, and/or third-party appraisals to establish a residual position. FMV and Split-TRAC leases have residual risk due to their unguaranteed residual value whereas TRAC leases have a guaranteed residual value. Expected credit losses on direct financing leases and the related estimated residual values are included in the Commercial and Industrial loan segment for the ACL.

Note 9 — 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 1 8. 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 receive a 100% match of their 401(k) plan contribution from the Company, up to 4% of their salary. We expensed $4.6 million for the three months ended March 31, 2024 and $4.5 million for the three months ended March 31, 2023 related to the Company’s employees’ 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 10 — 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 11 — 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 Atlantic Capital Bancshares, Inc. (“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.

​

​

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 three months of 2024. Because all outstanding stock options had vested as of December 31, 2023, there was no unrecognized compensation cost related to nonvested stock option grants under the plans or fair value of shares vested for the three months ended March 31, 2024. The intrinsic value of stock option shares exercised for the three months ended March 31, 2024 was $107,000.

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.

​

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.

​

As of March 31, 2024, there was $409,000 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 0.78 years as of March 31, 2024. The total fair value of shares vested during the three months ended March 31, 2024 was $852,000.

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 for the three months ended March 31, 2024 is summarized in the following table.

​

​ | ​ | ​ | ​ | ​ | ​ | ​

The nonvested shares of 876,952 at March 31, 2024 includes 65,307 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 2022, 2023 and 2024 Long Term Incentive performance-based RSU grants, an additional 134,079 shares in total may be issued by the Company at the end of the three-year performance periods.

As of March 31, 2024, there was $41.7 million of total unrecognized compensation cost related to nonvested RSUs granted under the plan. This cost is expected to be recognized over a weighted-average period of 1.54 years as of March 31, 2024. The total fair value of RSUs vested and released during the three months ended March 31, 2024 was $28.5 million.

Note 12 — 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 March 31, 2024, commitments to extend credit and standby letters of credit totaled $9.5 billion. As of March 31, 2024, the liability recorded for expected credit losses on unfunded commitments, excluding unconditionally cancellable exposures and letters of credit, was $53.2 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 March 31, 2024, any such liability is not expected to have a material effect on our consolidated financial statements.

​

In response to the bank failures in early 2023, the FDIC implemented a special assessment to recover the losses to the FDIC’s Deposit Insurance Fund at an annual rate of approximately 13.4 basis points over eight quarterly assessment periods beginning with the first quarterly assessment period of 2024. The base for the special assessment is equal to an insured depository institution’s estimated uninsured deposits reported as of December 31, 2022, adjusted to exclude the first $5 billion. As a result, approximately $25.7 million was recognized by the Bank as of December 31, 2023 for the two-year special assessment period. Due to additional losses to the Deposit Insurance Fund resulting from the 2023 bank failures reported by the FDIC in February 2024, an additional $3.9 million was accrued by the Bank during the first quarter of 2024, bringing the total estimated FDIC special assessment allocable to the Bank to approximately $29.5 million. The FDIC may impose additional special assessments from time to time based on the actual losses incurred by the FDIC as a result of the March 2023 bank failures or future failures.

Cyber Incident Litigation. On April 3, 2024, a putative class action lawsuit was filed against the Bank in the U.S. District Court for the Middle District of Florida, Tampa Division (the “Original Suit”). The plaintiff, who purports to represent the class of individuals harmed by alleged actions and/or omissions by the Bank in connection with the cybersecurity incident that was detected on February 6, 2024 (the “Cyber Incident”), asserts a variety of common law and statutory claims seeking monetary damages, injunctive relief and other related relief related to the potential unauthorized access by third parties to personal identifiable information. Since April 3, 2024, additional putative class action lawsuits have been filed and are currently pending against the Bank, including nine additional cases pending in the U.S. District Court for the Middle District of Florida, one case pending in the U.S. District Court for the District of South Carolina, two cases pending in the U.S. District Court for the Northern District of Georgia, and one case pending in the Circuit Court for Polk County, Florida. (each, a “Cyber Incident Suit”).

At this time, neither the Bank nor the Company is able to reasonably estimate the amount or range of reasonably possible loss, if any, that might result from the Cyber Incident Suits. However, the Bank believes that it has defenses to the claims and intends to vigorously defend against the Cyber Incident Suits. Accordingly, no amounts have been recorded in the unaudited condensed consolidated financial statements for the Cyber Incident Suits. The Company will continue to evaluate information as it becomes known and will record an estimate for losses at the time or times when it is both probable that a loss has been incurred and the amount of the loss is reasonably estimable. Additional lawsuits and claims related to the Cyber Incident may be asserted by or on behalf of customers, stockholders, or others seeking damages or other related relief and additional inquiries from governmental agencies may be received or investigations by governmental agencies commenced.

Note 13 — 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, 2023.

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 Company also has opted for the fair value option for the SBA servicing asset, as it is the industry-preferred method for valuing such assets.

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 three months ended March 31, 2024. A reconciliation of the beginning and ending balances of the MSR, a Level 3 asset recorded at fair value on a recurring basis, for the three months ended March 31, 2024 is as follows. The changes in fair value of the MSRs are recorded in Mortgage Banking Income on the Consolidated Statements of Income.

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 in the table below are based on pertinent information available to management as of March 31, 2024 and December 31, 2023. 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, 2023.

Balance Sheet Fair Value Hedge

As of March 31, 2024 and December 31, 2023, the Company maintained loan swaps, with an aggregate notional amount of $9.1 million and $9.2 million, respectively, accounted for as fair value hedges. The amortized cost basis of the loans being hedged were $9.6 million and $9.7 million, respectively, as of March 31, 2024 and December 31, 2023. 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.

​

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 March 31, 2024 and December 31, 2023, the interest rate swaps had an aggregate notional amount of approximately $22.9 billion and $22.6 billion, respectively. At March 31, 2024, the fair value of the interest rate swap derivatives is recorded in other assets at $174.0 million and in other liabilities at $954.3 billion. The fair value of derivative assets at March 31, 2024 was reduced by $781.1 million in variation margin payments applicable to swaps centrally cleared through LCH and CME. At December 31, 2023, the fair value of the interest rate swap derivatives was recorded in other assets at $169.0 million and other liabilities at $803.5 billion. The fair value of derivative assets at December 31, 2023 was reduced by $635.3 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 Income. There was a net gain of $113,000 recorded on these derivatives for the year ended March 31, 2024. There was a net gain of $96,000 recorded on these derivatives for the quarter ended March 31, 2023. As of March 31, 2024, we provided $237.8 million of cash collateral on the customer swaps, which is included in Cash and Cash Equivalents on the Consolidated Balance Sheets as Deposits in Other Financial Institutions (Restricted Cash). We also provided $99.5 million in investment securities at market value as collateral on the customer swaps which is included in Investment Securities – available for sale on the Consolidated Balance Sheets. Counterparties provided $53.7 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.

​

As of March 31, 2024, the Company maintained an aggregate notional amount of $1.8 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 Income. There was a net loss of $1,000 for these derivatives for the three months ended March 31, 2024. There was a net loss of $5,000 for these derivatives for the year ended December 31, 2023.

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. If there were foreign currency contracts outstanding at March 31, 2024, 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 months ended March 31, 2024 and 2023.

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 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 March 31, 2024, we had derivative financial instruments outstanding with notional amounts totaling $107.0 million related to MSRs, compared to $142.0 million on December 31, 2023. The estimated net fair value of the open contracts related to the MSRs was recorded as a gain of $381,000 at March 31, 2024, compared to a gain of $2.6 million at December 31, 2023.

Note 16 — 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.

​

Under current regulations, the Company and the Bank are subject to a minimum required 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, 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 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.

​

As of March 31, 2024 and December 31, 2023, the capital ratios of the Company and the Bank were well in excess of the minimum regulatory requirements and exceeded the thresholds for the “well capitalized” regulatory classification.

​

With the implementation of ASU 2016-13 in January 2020, 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 25% being phased out in 2024.

Amortization expense totaled $6.0 million for the quarter ended March 31, 2024, compared to $7.3 million for the quarter ended March 31, 2023. 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 applies 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 excludes the SBA servicing asset from the future amortization expense table presented below. The fair value of the SBA servicing asset was $6.4 million and $6.0 million, respectively, at March 31, 2024 and December 31, 2023. The fair value of the SBA servicing asset is included in Core Deposit and Other Intangibles on the Consolidated Balance Sheets.

Note 18 — 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 March 31, 2024 and December 31, 2023. Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts and disbursing payments to investors. The amounts of contractually specified servicing fees we earned during the three months ended March 31, 2024 and March 31, 2023 were $4.2 million and $4.1 million, respectively. Servicing fees are recorded in Mortgage Banking Income in our Consolidated Statements of Income.

​

At March 31, 2024 and December 31, 2023, MSRs were $88.0 million and $85.2 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 Income. The market value adjustments related to MSRs recorded in Mortgage Banking Income for the three months ended March 31, 2024 and March 31, 2023 were gains of $2.4 million, compared with losses of $1.3 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 13 — 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.

​

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 13 — Fair Value for additional information regarding fair value.

​

The characteristics and sensitivity analysis of the MSRs are included in the following table.

​

The sensitivity calculations above are hypothetical and should not be considered to be predictive of future performance. Changes in fair value based on changes in assumptions generally cannot be extrapolated because the relationship of the change in assumption to the change in fair value may not be linear. Also, the effect of a variation in a particular assumption on the fair value of the residential MSRs is calculated without changing any other assumption, while in reality changes in one factor may result in changes in another, which may either magnify or counteract the effect of the change. The derivative instruments utilized by the Company would serve to reduce the estimated impacts to fair value included in the table above.

​

Whole loan sales were $222.6 million for the three months ended March 31, 2024, compared to $159.4 million for the three months ended March 31, 2023. For March 31, 2024, $160.7 million, or 72.2%, were sold with the servicing rights retained by the Company, compared to $123.0 million, or 77.2% for March 31, 2023.

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, 2023. 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 three months ended March 31, 2024 and March 31, 2023 were approximately $117,000 and $345,000, respectively. There were approximately $9,000 and $11,000 in loss reimbursement and settlement claims paid during the three months ended March 31, 2024 and 2023, respectively.

​

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 $56.6 million and $50.9 million at March 31, 2024 and December 31, 2023, respectively. Please see Note 13 — 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 19 — 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 Securities Sold Under Agreements to Repurchase on the Consolidated Balance Sheets. At March 31, 2024 and December 31, 2023, our repurchase agreements totaled $281.3 million and $241.0 million, respectively. All of our repurchase agreements were overnight or continuous (until-further-notice) agreements at March 31, 2024 and December 31, 2023. These borrowings were collateralized with government, government-sponsored enterprise, or state and political subdivision-issued securities with a carrying value of $397.7 million and $410.4 million at March 31, 2024 and December 31, 2023, 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 March 31, 2024 and December 31, 2023, our federal funds purchased totaled $273.4 million and $248.2 million, respectively.

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

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 March 31, 2024 and December 31, 2023, the Company had $0 and $100.0 million, respectively, of outstanding FHLB borrowings. Net eligible loans of the Company pledged via a blanket lien to the FHLB for advances and letters of credit at March 31, 2024, were approximately $11.3 billion (collateral value of $6.5 billion) and investment securities and cash pledged were approximately $145.4 million (collateral value of $122.9 million). This allows the Company a total borrowing capacity at the FHLB of approximately $6.6 billion. After accounting for letters of credit totaling $2.9 million, the Company had unused net credit available with the FHLB in the amount of approximately $6.6 billion at March 31, 2024. The Company also has a total borrowing capacity at the FRB of $1.8 billion at March 31, 2024 secured by a blanket lien on $2.6 billion (collateral value of $1.8 billion) in net eligible loans of the Company. The Company had no outstanding borrowings with the FRB at March 31, 2024 or December 31, 2023.

Note 21 — Investments in Qualified Affordable Housing Projects

The Company has investments in qualified affordable housing projects (“QAHPs”) that provide low-income housing tax credits (“LIHTC”) and operating loss benefits over an extended period. Effective January 1, 2024, the Company adopted ASU No. 2023-02 and began to apply the proportional amortization method of accounting for its QAHPs. Prior to the adoption of ASU No. 2023-02, the Company applied the equity method of accounting for its QAHPs. For the three months ended March 31, 2024, the Company recorded $3.8 million in tax credits and other tax benefits and $3.4 million of amortization attributable to the QAHPs within Provision for Income Taxes on its Consolidated Statement of Income. For the three months ended March 31, 2023, the Company recorded $3.6 million of tax credits and other tax benefits within Provision for Income Taxes and amortization of $2.0 million within Other Noninterest Expense on the Consolidated Statement of Income. At March 31, 2024 and December 31, 2023, the Company’s carrying value of QAHPs was $88.5 million and $101.8 million, respectively, recorded in Other Assets on the Consolidated Balance Sheet. The Company had $11.9 million and $12.5 million in remaining funding obligations related to these QAHPs recorded in Other Liabilities on the Consolidated Balance Sheets at March 31, 2024 and December 31, 2023, respectively. For the remaining funding obligations at March 31, 2024, approximately 92% are expected to be funded by 2026. For more information on the adoption of ASU 2023-02, refer to Recent Accounting and Regulatory Pronouncements under Note 3 — Recent Accounting and Regulatory Pronouncements.

Note 22 — Subsequent Events

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 holding company also owns SSB Insurance Corp., a captive insurance subsidiary pursuant to Section 831(b) of the U.S. Tax Code.

​

At March 31, 2024, we had approximately $45.1 billion in assets and 5,179 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.

Table of Contents

The following discussion describes our results of operations for the quarter ended March 31, 2024 compared to the quarter ended March 31, 2023 and also analyzes our financial condition as of March 31, 2024 as compared to December 31, 2023. 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.

Critical Accounting Policies

Our consolidated financial statements are prepared based on the application of accounting policies in accordance with Generally Accepted Accounting Principles (“GAAP”) and follow general practices within the banking industry. Our financial position and results of operations are affected by management’s application of accounting policies, including estimates, assumptions and judgments made to arrive at the carrying value of assets and liabilities and amounts reported for revenues and expenses. Differences in the application of these policies could result in material changes in our consolidated financial position and consolidated results of operations and related disclosures. 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, 2023.

Results of Operations

Overview

We reported consolidated net income of $115.1 million, or diluted earnings per share (“EPS”) of $1.50, for the first quarter of 2024 as compared to consolidated net income of $139.9 million, or diluted earnings of $1.83, in the comparable period of 2023, a 17.8% decrease in consolidated net income and a 18.0% decrease in diluted EPS. The $24.9 million decrease in consolidated net income was the net result of the following items:

| ● | A $66.8 million increase in interest income, resulting from a $70.3 million increase in interest income from loans and loans held for sale partially offset by a $2.8 million decrease in interest income from investment securities, and a $667,000 decrease in interest income on federal funds sold, securities purchased under agreement to resell and interest-bearing deposits. The increase in interest income from loans was due to an increase in the yield as loans continued to reprice higher from the rising rate environment in 2022 and in 2023 as the Federal Reserve Bank raised its federal funds rate by 525 basis points. The increase in interest income was also due to an increase in the average balance of loans of $2.1 billion through organic loan growth;

| ● | A $104.2 million increase in interest expense, which resulted from a $104.2 million increase in interest expense from deposits, a $1.9 million increase in interest expense in federal funds purchased and securities sold under agreements to repurchase partially offset by a $1.9 million decrease in interest expense from corporate and subordinated debentures and other borrowings. The increase in interest expense from deposits resulted mainly from an increase in costs due to the higher interest rate environment with the increase in interest rates in 2022 and 2023. This increase in average cost of deposits was felt throughout 2023 starting with the stress in the financial markets and liquidity that occurred in March 2023 with the closure of a few failed financial institutions. The average cost of deposits, excluding non-interest bearing deposits, increased by 147 basis points compared to the first quarter of 2023;

| ● | A $20.4 million decrease in the provision for credit losses, as the Company recorded a provision for credit losses of $12.7 million in the first quarter of 2024 while recording a provision for credit losses of $33.1 million in the first quarter of 2023. During the first quarter of 2024, we recorded a lower provision for credit losses as economic forecasts improved since the first quarter of 2023, with inflation falling and interest rates stabilizing, along with lower new loan growth in the first quarter of 2024 compared to the same period in 2023;

| ● | A $203,000 increase in noninterest income, primarily from an increase in service charges on deposit accounts of $2.0 million, in debit prepaid, ATM and merchant card related income of $1.2 million, in mortgage banking income of $1.8 million and in other noninterest income of $3.3 million. The increase in other noninterest income is mainly attributable to the recognition of credit from an external vendor of $2.5 million during the first quarter of 2024. These increases were mostly offset by a decline in correspondent banking and capital market income of $9.3 million. See Noninterest Income section on page 52 for further discussion;

| ● | An $8.8 million increase in noninterest expense, which resulted primarily from an increase in salaries and employee benefits of $6.4 million, an accrual for the FDIC special assessment of $3.9 million, in FDIC assessment and other regulatory charges of $2.2 million, and an information services expense of $2.4 million. These increases were partially offset by declines in merger, branch consolidation, severance related and other expense of $4.9 million and amortization of intangibles of $1.3 million. See Noninterest Expense section on page 54 for further discussion; and

| ● | Lower income tax provision of $634,000 primarily due to lower pretax book income between the two quarters. The Company recorded pretax book income of $153.5 million in the first quarter of 2024 compared to pretax book income of $179.0 million in the first quarter of 2023. The effects of the lower pretax book income were mostly offset by the effects of the Company adopting ASU 2023-02 in the first quarter of 2024 whereby it applied the proportional amortization method of accounting related to its low income housing tax credits partnerships (“LIHTC”). With the adoption of ASU 2023-02, the amortization of the LIHTCs is now recorded within Provision for Income Taxes rather than Other Noninterest Expense on the Statement of Income. The amortization for the Company’s LIHTCs totaled $3.5 million during the first quarter of 2024. The change in the accounting method, in addition to other items recorded during the current quarter, increased our effective tax rate for the first quarter in 2024 compared to the same period in 2023. Our effective tax rate was 25.05% for the three months ended March 31, 2024 compared to 21.84% for the three months ended March 31, 2023. See Income Tax Expense section on page 55 for further discussion.

Our quarterly efficiency ratio increased to 58.5% in the first quarter of 2024 compared to 51.4% in the first quarter of 2023. The increase in the efficiency ratio compared to the first quarter of 2023 was the result of an 8.3% decrease in the total of tax-equivalent net interest income and noninterest income along with a 4.3% increase in noninterest expense (excluding amortization of intangibles). This decrease was reflective of a 150.7% increase in interest expense as the repricing of interest-bearing liabilities caught up with the repricing of interest-earning assets in 2023 and into the first quarter of 2024 resulting from the rising rate environment.

​

Basic and diluted EPS were $1.51 and $1.50, respectively, for the first quarter of 2024, compared to $1.84 and $1.83, respectively for the first quarter of 2023. The decrease in basic and diluted EPS was due to a 17.8% decrease in net income in the first quarter of 2024 compared to the same period in 2023 along with an increase in average basic common shares of 0.5%. The decrease in net income in the first quarter of 2023 was mainly attributable to an increase in interest expense pertaining to interest-bearing liabilities resulting from the rising rate environment as noted above.

| ● | For the three months ended March 31, 2024, the return on average assets declined compared to the same period in 2023. This decrease was primarily due to the decrease in net income of $24.9 million, or 17.8%, which was attributable to an increase in the cost of interest-bearing liabilities resulting from the rising rate environment. The decline in the return on average assets was also due to an increase in average assets for the three months ended March 31, 2024 of $906.7 million, or 2.1%, compared to the same period in 2023, mainly due to an increase in loans of $2.1 billion through organic growth.

| ● | For the three months ended March 31, 2024, the return on average equity and the return on average tangible equity declined compared to the same period in 2023. These decreases were primarily due to lower net income of 17.8%, along with an increase in average equity of 6.9% and tangible equity of 12.3%.

| ● | The equity-to-assets ratio was 12.29% for the three months ended March 31, 2024, an increase of 0.61% from March 31, 2023. This increase resulted from net income earned during the last twelve months being greater than the increase in total assets of 0.5% from March 31, 2023.

| ● | Dividend payout ratios were 34.42% for the three-month period ending March 31, 2024 and 27.09% for the three-month period ending March 31, 2023. The increase in the dividend payout ratio for the three months ended March 31, 2024 was due to the 17.8% decrease in net income along with total dividends paid during the first quarter of 2024 increasing 4.4% compared to the same period in 2023.

Net Interest Income and Margin

Non-Tax Equivalent (“TE”) net interest income decreased $37.3 million, or 9.8%, to $343.9 million in the first quarter of 2024 compared to $381.3 million in the same period in 2023. Interest earning assets averaged $40.7 billion during the three months period ended March 31, 2024 compared to $39.4 billion for the same period in 2023, an increase of $1.2 billion, or 3.2%. Interest bearing liabilities averaged $27.5 billion during the three months period ended March 31, 2024 compared to $24.6 billion for the same period in 2023, an increase of $2.9 billion, or 11.7%.

The Federal Reserve made four 25 basis-point rate increases during 2023, starting early February 2023 with the most recent increase in late July 2023, resulting in a range of 5.25% to 5.50% at March 31, 2024. As a result, the Company operated under a higher rate environment for the first quarter of 2024 while it operated under a comparatively lower rate environment in the first quarter of 2023. Some key highlights are outlined below:

| ● | Both the non-TE and TE net interest margin decreased by 52 basis points in the first quarter of 2024 compared to the same quarter of 2023 due to the increase in the cost of interest-bearing liabilities of 139 basis points outweighing the increase in the yield on interest earning assets of 48 basis points. The increase in the cost of interest-bearing liabilities lagged the increase in yield on interest-earning assets during this rising interest rate cycle and has caught up in the latter half of 2023 and into the first quarter of 2024.

| o | Non-TE yield on interest-earning assets for the first quarter of 2024 increased by 48 basis points to 5.12% from the comparable period in 2023 due to higher yields on the majority of interest-earning assets, including loans held for investment, investments securities, and federal funds sold and interest-earning deposits with banks, as the Federal Reserve Bank raised interest rates during 2023. The increases in interest rates, in combination with the increase in the average balance of the higher yielding loan portfolio of $2.1 billion, the decline in the average balances of lower yielding investment securities of $766.8 million and federal funds sold and interest-earning deposits with banks of $90.9 million, affected the overall yield increase between the comparable periods.

| o | The average cost of interest-bearing liabilities for the first quarter of 2024 increased by 139 basis points to 2.53% from the same period in 2023. This increase was driven by the effects from the higher rate environment on the repricing of all deposit accounts, federal funds purchased, securities purchased with agreement to repurchase, trust preferred corporate debt, and other borrowings. The average cost of interest-bearing deposits increased by 147 basis points as the increase occurred in all deposit categories and was a result of the rising rate environment and a change in the deposit mix. Our deposits have shifted from lower-costing savings and transaction deposit accounts to higher-costing certificates and other time deposits and money market accounts as customers have sought higher yields during the rising rate environment. The average cost of securities sold with agreements to repurchase and federal funds purchased increased 123 by basis points and 69 basis points, respectively, while the average cost of corporate and subordinated debentures increased by 24 basis points. Other borrowings, consisting of FHLB advances had an average cost of 5.66% during the first quarter of 2024 compared to 4.76% for the compared period in 2023. Our overall cost of funds, including noninterest-bearing deposits, was 1.83% for the three months ended March 31, 2024 compared to 0.75% for the three months ended March 31, 2023.

Investment Securities

​

The interest earned on investment securities decreased by $2.8 million in the three months ended March 31, 2024 compared to the three months ended March 31, 2023. This is a result of the Bank carrying a lower average balance in investment securities in 2024 compared to the same period in 2023. The average balance of investment securities for the three months ended March 31, 2024 decreased by $766.8 million from the comparable period in 2023. This decrease was due to maturities, mortgage paydowns and sales within the AFS and HTM investment portfolios being greater than the purchases of these securities as the Company has only purchased $80.4 million in AFS and HTM securities since March 31, 2023. The effects from the decline in average balance were partially offset by the increase in yield. The yield on the total investment securities increased by 7 basis points during the three months ended March 31, 2024 compared to the same periods in 2023 due to the rising rate environment.

Loans

​

Interest earned on loans held for investment increased by $70.0 million to $463.0 million in the first quarter ended March 31, 2024 from the comparable period in 2023. Interest earned on loans held for investment included loan accretion income recognized during the quarters ended March 31, 2024 and 2023 of $4.3 million and $7.4 million, respectively, a decrease of $3.1 million. Some key highlights for the quarter ended March 31, 2024 are outlined below:

| ● | Our non-TE yield on total loans increased by 49 basis points in the first quarter of 2024 compared to the same period in 2023 due to a 60 basis-point increase in yield on the non-acquired loan portfolio and a 29 basis-point increase in the yield on the acquired loan portfolio.

| o | The yield on the acquired loan portfolio increased by 29 basis points to 6.26% in the first quarter of 2024 from 5.97% in the same period in 2023, while interest income on the acquired loan portfolio decreased by $15.8 million during the same period.

| ◾ | The interest income on acquired loans decreased due to a $1.4 billion decrease in average balance during the first quarter of 2024 compared to the same period in 2023. The average balance decreased due to paydowns, pay-offs and renewals of acquired loans that are moved to our non-acquired loan portfolio. The effect from the decline in average acquired loans balance was partially offset by the increase in yield of 29 basis points.

| o | The yield on the non-acquired loan portfolio increased by 60 basis points to 5.62% in the first quarter of 2024 compared to 5.02% in the same period in 2023. Interest income on the non-acquired loan portfolio increased by $85.9 million during the same period.

| ◾ | The increases in both yield and interest income on non-acquired loans were attributable to both a higher average balance of $3.5 billion through organic loan growth and renewals of matured acquired loans that are moved to our non-acquired loan portfolio, along with a higher yield of 60 basis points due to the higher rate environment.

Interest-Bearing Liabilities

​

The quarter-to-date average balance of interest-bearing liabilities increased by $2.9 billion, or 11.7%, in the first quarter of 2024 compared to the same period in 2023. The cost of interest-bearing liabilities increased by 139 basis points to 2.53% and the overall cost of funds, including demand deposits, increased by 108 basis points to 1.83% in the first quarter of 2024 compared to the same period in 2023. Some key highlights for the quarter ended March 31, 2024 compared to the same period in 2023 include:

| ● | The cost of interest-bearing deposits was 2.44% for the first quarter of 2024 compared to 0.97% for the same period in 2023.

| o | Interest expense on interest-bearing deposits increased by $104.2 million in the first quarter of 2024 compared to the same period in 2023 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 by $76.8 million, $62,000, and $27.4 million, respectively. One factor driving the increase in average cost and interest expense was the repricing of deposits in the higher rate environment in 2024 compared to the first quarter of 2023. The increase in the cost of interest-bearing deposits lagged the increase in the yield on interest-earning assets during this rising interest rate cycle and has caught up in the latter half of 2023 and into the first quarter of 2024.

| o | The average balance of interest-bearing deposits increased by $3.1 million, driving up interest expense. The increase in average balance of interest-bearing deposit was due to an increase in the average balance of transaction and money market accounts of $2.7 billion, along with an increase in the average balance of higher costing time deposits of $1.2 billion, partially offset by a decrease in average saving deposits of $709.0 million. The increase in average cost and interest expense was also due to a change in deposit mix. During the rising rate environment, our deposits have shifted from lower-costing savings and transaction deposit accounts to higher-costing certificates and other time deposits and money market accounts with customers seeking higher yields.

| ● | The cost of federal funds purchased increased by 69 basis points in the first quarter of 2024 due to the rising rate environment. This increase in cost along with the increase in the average balance of $63.2 million drove the $1.2 million increase in interest expense compared to the same period in 2023.

​

51

Table of Contents

| ● | The cost of repurchase agreements was 1.95% for the first quarter of 2024 compared to 0.72% for the same period in 2023 driven by the effects from the higher interest environment. The effects from the increase in the cost of repurchase agreements, partially offset by the effects from a decline in the average balance of $92.9 million, drove the increase in the interest expense of $692,000 during the first quarter of 2024 compared to the same period in 2023.

| ● | The cost of the corporate and subordinated debt increased by 24 basis points to 6.17% for the three months ended March 31, 2024 compared to the same period in 2023, also driven by the effects from the rising rate environment on the repricing of variable rate corporate debentures. The interest expense from corporate and subordinated debentures increased by $274,000 during the first quarter of 2024 compared to the same period in 2023 due to the increase in average cost.

| ● | The cost of other borrowings, consisting of FHLB advances, for the three months ended March 31, 2024 was 5.66% and interest expense was $2.4 million compared to 4.76% and $4.6 million during the first quarter of 2023. The decline in interest expense was due to a decline in the average balance of other borrowings of $221.4 million from $393.3 million during the first quarter of 2023 compared to $172.0 million during the same period in 2024. The Bank used FHLB advances in the first quarter of 2023 to provide excess liquidity during the financial turmoil from the closures of failed banks in 2023, having $900 million in outstanding advances at March 31, 2023.

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, Interest on Lawyers’ Trust Accounts (“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 by $2.2 billion, or 17.5%, to $10.5 billion in the first quarter of 2024 compared to $12.8 billion during the same period in 2023. The decrease in the average balance of noninterest bearing deposits was due to customers moving funds from noninterest bearing checking accounts to seek higher yields resulting from the rising rate environment, along with customers having less excess cash as funds from government support programs related to the COVID-19 pandemic began to decline.

Noninterest Income

​

Noninterest income provides us with additional revenues that are significant sources of income. For the three months ended March 31, 2024 and 2023, noninterest income comprised 17.2% and 15.8%, respectively, of total net interest income and noninterest income.

Noninterest income increased by $203,000, or 0.3%, during the first quarter of 2024 compared to the same period in 2023. This quarterly change in total noninterest income resulted from the following:

| ● | Service charges on deposit accounts were higher by $2.1 million, or 10.0%, in the first quarter of 2024 compared to the same period in 2023. The increase was mainly attributable to a $1.2 million increase in Non-Sufficient Fund (“NSF”) fees, a $674,000 increase in account maintenance fees, and approximately $209,000 increase in other services charges during the first quarter of 2024 compared to the same period in 2023.

Table of Contents

| ● | Debit, prepaid, ATM and merchant card related income increased by $1.2 million, or 13.3%, during the first quarter of 2024 compared to the same period in 2023. The increase was primarily driven by an increase in debit/ATM fee income, net of card expense.

| ● | Mortgage banking income increased by $1.8 million, or 42.4%, during the first quarter of 2024 compared to the same period of 2023, which comprised of a $950,000, or 60.7%, increase in mortgage servicing related income and a $887,000, or 32.1%, increase in secondary market mortgage income. Mortgage production declined from $556.0 million in the first quarter of 2023 to $428.8 million in the first quarter of 2024 with higher mortgage rates continuing during 2024. We allocated a higher percentage of mortgage production to the secondary market in the first quarter of 2024 compared to the same period in 2023 as the percentage allocated increased from 28% to 53%. 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 year to year.

| o | The increase in mortgage servicing related income, net of the hedge, in the first quarter of 2024 was primarily due to a $916,000 increase in the change in fair value of the MSR including decay. The increase in fair value of the MSR between the comparable periods was primarily due to an increase in the change in fair value from interest rates of $3.7 million, offset by a decrease from gains/losses on the MSR hedge of $2.7 million and a $33,000 decline in MSR decay.

| o | Mortgage income from the secondary market increased by $887,000 between the comparable periods resulting from decreases in the change in fair value of the pipeline of $449,000 and loans held for sale of $135,000, offset by an increase in the fair value of MBS forward trades of $1.5 million and a $5,000 increase in the gain on sale of mortgage loans, which is net of the commission expense related to mortgage production. Mortgage commission expense was $2.2 million during the first quarter of 2024 compared to $1.3 million during the comparable period in 2023.

| ● | Trust and investment services income for the first quarter of 2024 increased by $454,000, or 4.6%, from the first quarter of 2023 as assets under management have increased by $881.5 million, or 11.9%, in that same time frame.

| ● | Correspondent banking and capital markets income in the first quarter of 2024 decreased by $9.3 million, or 68.3%, compared to the same period in 2023. The decline was primarily related to a decrease of $6.3 million in income generated from the sale of customer swap ARC hedges during the first quarter of 2024 compared to the first quarter of 2023 resulting from the higher interest rate environment in 2024. The decline was also due to the expense attributable to the variation margin payments for centrally cleared swaps where we recorded an expense of $10.3 million related to variation margin payments in the first quarter of 2024 compared to an expense of $8.4 million in the first quarter of 2023. In addition, commissions and fees earned on fixed income security sales were lower by $917,000 in the first quarter of 2024 compared to the same period in 2023.

| ● | SBA income increased by $641,000, or 17.2%, during the first quarter of 2024 compared to the same period in 2023. SBA income includes changes in fair value of the servicing asset, loan servicing fees and gains on sale of SBA loans. The increase was attributable to higher gains on sale of SBA loans of $802,000, partially offset by declines in SBA servicing fee income and the change in fair value of the SBA servicing asset of $123,000 and $38,000, respectively.

| ● | Other income increased by $3.2 million, or 105.9%, in the first quarter of 2024 compared to the same quarter in 2023. This increase was primarily due to the Bank recognizing approximately $2.5 million in credits from an external vendor during the first quarter of 2024.

Noninterest expense increased by $8.8 million, or 3.7%, in the first quarter of 2024 compared to the same period in 2023. The quarterly increase in total noninterest expense primarily resulted from the following:

| ● | Salaries and employee benefits increased by $6.4 million, or 4.4%, in the first quarter of 2024 compared to the same period in 2023. The increase was primarily due to an increase in salaries of $6.6 million resulting from merit increases and an increase in the number of employees, along with higher employee benefits of $2.2 million from higher FICA tax paid and medical insurance expense. These increases were partially offset by a decrease in commissions of $2.2 million, which is mainly attributable to lower commissions related to the correspondent banking division resulting from lower bond sales and lower income from the ARC hedging program.

| ● | Information services expense increased by $2.4 million, or 12.2% in the first quarter of 2024 compared to the same period in 2023. The increase was due to additional cost associated with the Company updating systems and software as it grows in size and complexity.

| ● | Amortization of intangibles, which is related to the Company’s prior mergers, decreased by $1.3 million, or 17.8%.

| ● | Professional fees decreased by $587,000, or 15.9%, primarily due to lower legal and other general business consulting expenses incurred in the first quarter of 2024 compared to the same period in 2023.

| ● | FDIC assessment and other regulatory charges increased by $2.2 million, or 35.6%, in the first quarter of 2024 compared to the same period in 2023. The increase in the FDIC assessment was primarily due to an increase in the FDIC assessment rate to bring the overall FDIC fund to 1.35x total deposits by the end of 2028. The increase also reflects changes in the Company’s size and complexity along with the effects from the increase in the Company’s classified assets.

| ● | The Company accrued an additional $3.9 million related to the FDIC’s special assessment introduced in 2023 to recover losses to the FDIC’s Deposit Insurance Fund resulting from the bank failures that occurred in early 2023. The FDIC notified banks in the first quarter of 2024 the estimate of the losses expected from the bank failures were larger than originally estimated. As a result, the Bank increased its accrual of the FDIC special assessment in anticipation of the higher assessment that may be allocated to the Bank.

| ● | Merger, branch consolidation, severance related and other expense decreased by $4.9 million, or 52.1%, to $4.5 million in the first quarter of 2024 compared to the same period in 2023. Of the $4.5 million in 2024, approximately $4.4 million pertains to one-time costs associated with the cybersecurity incident, which was identified as an isolated event as previously disclosed by the Company. The Company did not incur any merger expense pertaining to prior acquisitions during the first quarter of 2024, while it had a total of $1.3 million merger expense associated with the Atlantic Capital acquisition during the comparative period in 2023. In the first quarter of 2023, the Company also recorded $8.1 million in restructuring costs. The restructuring costs included approximately $7.0 million of severance related expense pertaining to the elimination of the Company’s executive officer position and approximately $1.1 million of severance related expense pertaining to the reduction in force of the Company’s mortgage division.

| ● | Other noninterest expense decreased by $432,000, or 2.5%, in the first quarter of 2024 compared to the same period in 2023. This decrease primarily resulted from a $2.1 million decline in amortization expenses related to the adoption of ASU 2023-02 effective January 1, 2024, which changed the accounting method of the Company’s LIHTC structured investments. Starting in the first quarter of 2024, the amortization expense related to the Company’s LIHTC investments is being recorded within Provision for Income Taxes on the Consolidated Statement of Income. Additionally, there was a $1.2 million decrease in tax payments due to higher other franchise taxes incurred during the first quarter of 2023, and a $642,000 decrease in incurred but not reported insurance loss reserves. These decreases were offset by a $3.3 million increase in earnings credit expense to Homeowners Association (“HOA”) customers. The Bank provides a credit to HOA customers based on the average deposit balances held that reduces fees for other services provided.

Income Tax Expense

Our effective tax rate was 25.05% for the three months ended March 31, 2024 compared to 21.84% for the three months ended March 31, 2023. The increase in the effective rate for the quarter, when compared to the same period in the prior year, is driven by amortization of LIHTCs as a result of the adoption of the proportional amortization under ASU 2023-02 effective January 1, 2024, as well as an increase in non-deductible FDIC premiums recorded during the current period. This was partially offset by a decrease in disallowed executive compensation and disallowed interest expense. In addition, the Company recorded approximately $2.8 million in income tax provision related to the revaluations of its deferred income taxes and other tax adjustments during the current period.

Analysis of Financial Condition

Summary

Our total assets increased by approximately $242.8 million, or 0.5%, from December 31, 2023 to approximately $45.1 billion at March 31, 2024. Within total assets, cash and cash equivalents increased by $210.6 million, or 21.1% and loans increased by $278.8 million or 0.9% during the period, while investment securities decreased by $231.6 million, or 3.1%. Within total liabilities, deposits grew $129.5 million, or 0.3%, and federal funds purchased and securities sold under agreements to repurchase increased by $65.5 million, or 13.4%. Total borrowings decreased by $100.1 million, or 20.3%. Total shareholder’s equity increased by $13.9 million, or 0.3%. The increase in cash and cash equivalents was primarily due to the increase in deposits of $129.5 million along with decline in investments of $231.6 million from maturities and pay downs of mortgage-backed securities. The increase in deposits was mainly from the increase in money market accounts of $356.7 million during the quarter. The increase in loans was due to normal organic growth. Our loan to deposit ratio was 88% and 87% at March 31, 2024 and December 31, 2023, respectively, while our percentage of non-interest bearing deposit accounts to total deposits was 28% and 29% at March 31, 2024 and December 31, 2023, respectively.

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 March 31, 2024, investment securities totaled $7.2 billion, compared to $7.5 billion at December 31, 2023, a decrease of $231.6 million, or 3.1%. At March 31, 2024, approximately 63.6% of the investment portfolio was classified as available for sale, approximately 33.8% was classified as held to maturity and 2.6% was classified as other investments. During the three months ended March 31, 2024, we purchased $54.6 million of capital stock with the Federal Home Loan Bank classified as other investment securities on the balance sheet of which we sold back $59.4 million. The net decrease to the capital stock holding for the Federal Home Loan Bank of Atlanta of $4.8 million during the first quarter of 2024 was due to the decrease in Federal Home Loan Bank borrowings. During the first quarter of 2024, the Bank did not purchase any securities available for sale or held to maturity. There were maturities, paydowns, and calls of investment securities totaling $168.4 million during the first quarter of 2024. Net amortization of premiums was $4.8 million in the first three months of 2024.

At March 31, 2024, the unrealized net loss of the available for sale securities portfolio was $830.2 million, or 15.3%, below its amortized cost basis, compared to an unrealized net loss of $776.6 million, or 14.0%, at December 31, 2023. At March 31, 2024, the unrealized net losses of the held to maturity securities portfolio was $430.0 million, or 17.6%, below its amortized cost basis, compared to an unrealized net losses of $402.7 million, or 16.2%, at December 31, 2023. The increase in the unrealized net loss in the available for sale investment portfolio of $53.6 and the increase in the unrealized net losses for the held to maturity portfolio of $27.3 during the first three months of 2024 was mainly due to the expectation that interest rates will remain higher in 2024 as inflation continues to remain higher than the Federal Reserve Bank target of 2.0%.

* 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 March 31, 2024, we had 1,236 investment securities, including both available for sale and held to maturity, which totaled $1.3 billion unrealized loss position. At December 31, 2023, we had 1,232 investment securities, including both available for sale and held to maturity, in an unrealized loss position, which totaled $1.2 billion. The total number of investment securities with an unrealized loss position increased by 4 securities, while the total dollar amount of the unrealized loss increased by $80.0 million. The level of unrealized losses for each period is due to an overall increase in short- and long-term interest rates in 2022 and 2023 and the expectation that interest rates will not fall until late 2024 or 2025.

​

All investment securities in an unrealized loss position as of March 31, 2024 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 4 — 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.

Other Investments

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 March 31, 2024, we determined that there was no impairment on our other investment securities. As of March 31, 2024, other investment securities represented approximately $187.3 million, or 0.41% of total assets, and primarily consists of FHLB and FRB stock which totals to approximately $168.3 million, or 0.37% of total assets. There were no gains or losses on the sales of these securities for three months ended March 31, 2024 and 2023, respectively.

Trading Securities

We have a trading portfolio associated with our Correspondent Banking 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 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 $66.2 million and $31.3 million at March 31, 2024 and December 31, 2023, respectively.

Loans Held for Sale

​

The balance of mortgage loans held for sale increased $5.7 million from December 31, 2023 to $56.6 million at March 31, 2024. Total mortgage production was $429 million in the first quarter of 2024. This compares to $436 million in the fourth quarter of 2023. Mortgage production has declined as mortgage rates have continued to remain high. The percentage of mortgage production sold into the secondary market increased to 53% at March 31, 2024 compared to 49% in the fourth 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 over time.

Total loans, net of deferred loan costs and fees (excluding mortgage loans held for sale), increased by $278.8 million, or 3.5% annualized, to $32.7 billion at March 31, 2024. Our non-acquired loan portfolio increased by $618.7 million, or 9.4% annualized, mainly driven by organic growth. Commercial non-owner occupied loans, consumer owner occupied loans, commercial and industrial loans, commercial owner occupied real estate, and home equity loans led the way with $621.6 million, $244.3 million, $112.6 million, $80.9 million and $25.1 million in year-to-date loan growth, respectively, or 39.1%, 16.6%, 9.8%, 8.1% and 8.8% annualized growth, respectively. The acquired loan portfolio decreased by $339.9 million, or 23.1% 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 and industrial loans and commercial owner occupied loans, which decreased by $80.8 million, $73.0 million and $66.7 million, respectively, during the quarter. Acquired loans as a percentage of total loans decreased to 17.0% and non-acquired loans as a percentage of the overall portfolio increased to 83.0% at March 31, 2024. This compares to acquired loans as a percentage of total loans of 18.2% and non-acquired loans as a percentage of total loans of 81.8% at December 31, 2023.

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, 2023 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 and unrest in middle east, 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 March 31, 2024, 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 consistent with the first 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 and recent commercial real estate market sales data still show resilience and actual loan losses remain at low levels, continued projected weakness in the forecasted commercial real estate price index continues to elevate 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 $12.7 million during the first quarter of 2024.

​

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, 2023 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 March 31, 2024, the balance of the ACL was $469.7 million or 1.44% of total loans. The ACL increased $13.1 million from the balance of $456.6 million recorded at December 31, 2023. The net increase during the first quarter of 2024 included a $15.8 million provision and $2.7 million in net charge-offs. During the three months ended March 31, 2024, the Company recorded a provision for credit losses based on loan growth and current forecasts applied to our modeling to adequately capture potential economic recessionary risks.

Total nonperforming assets were $174.5 million, or 0.53% of total loans and repossessed assets, at March 31, 2024, a decrease of $9.6 million, or 5.2%, from December 31, 2023. Total nonperforming loans were $172.3 million, or 0.53%, of total loans, at March 31, 2024, a decrease of $10.4 million, or 5.7%, from December 31, 2023. Non-acquired nonperforming loans decreased by $13.1 million from December 31, 2023. The decrease in non-acquired nonperforming loans was driven primarily by a decrease in commercial nonaccrual loans of $7.2 million, a decrease in accruing loans past due 90 days or more of $8.8 million, offset by an increase in consumer nonaccrual loans of $2.9 million. The accruing loans past due 90 days or more decreased by $8.8 million at March 31, 2024 compared to December 31, 2023, due primarily to a decrease in accruing loans past due 90 days or more of factored receivables, which are trade credits rather than promissory notes loans that are deemed to be low risk. Acquired nonperforming loans increased $2.7 million from December 31, 2023. The increase in the acquired nonperforming loan balances was due primarily to an increase in commercial nonaccrual loans of $4.6 million, offset by a decrease in consumer nonaccrual loans of $1.0 million and a decline in accruing loans past due 90 days or more of $1.0 million.

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 by $232.4 million, or 3.5% annualized, to $26.6 billion at March 31, 2024 from $26.4 billion at December 31, 2023. This increase was mainly driven by growth in money market accounts of $356.7 million, including $167.1 million in reciprocal insured money market deposits. This increase was partially offset by declines in interest-bearing checking accounts of $80.0 million and savings deposits of $75.0 million. Customers continue to move funds from lower yielding deposit products seeking higher yields in money market accounts. Federal funds purchases related to the Correspondent Banking Division and securities sold under agreements to repurchase were $554.7 million at March 31, 2024, a $65.5 million increase from December 31, 2023. Other borrowings, consisting of FHLB borrowings, decreased to $0 at March 31, 2024 from $100 million at December 31, 2023. Corporate and subordinated debentures declined by $92,000 to $391.8 million. Some key highlights are outlined below:

​

| ● | As noted above, the Company’s higher yielding money market accounts increased during the first quarter of 2024. The Company raised interest rates on most interest-bearing deposit products (in particular money market accounts and time deposit specials) due to competitive pressures to retain deposits. Average interest-bearing deposits increased by $3.1 billion to $26.4 billion in the quarter ended March 31, 2024 compared to the same period in 2023. For more information on the composition of our total deposits, see Note 8 – Deposits.

| ● | Other borrowings, consisting of FHLB borrowings, decreased to $0 at March 31, 2024 from $100 million at December 31, 2023. The Company paid down its FHLB borrowings in the first quarter of 2024 with the growth in deposits and the maturities and pay downs in investment securities providing liquidity.

Noninterest-Bearing Deposits

Noninterest-bearing deposits are transaction accounts that provide our Bank with “interest-free” sources of funds. At March 31, 2024, the period end balance of noninterest-bearing deposits of $10.5 billion remained fairly stable compared to the balance at December 31, 2023 of $10.6 billion. Average noninterest-bearing deposits were $10.5 billion for the first quarter of 2024 compared to $12.8 billion for the first quarter of 2023. This decrease in the average noninterest bearing deposits from the quarter ended March 31, 2023 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 began to decline, as well as the resulting effects of higher costs related to inflation.

Uninsured Deposits

At March 31, 2024 and December 31, 2023, the Company had approximately $13.3 billion and $14.2 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 March 31, 2024, shareholders’ equity was $5.5 billion, an increase of $13.9 million, or 0.3%, from December 31, 2023.

The following table shows the changes in shareholders’ equity during 2024.

​ | ​ | ​ | ​
(Dollars in thousands) | ​ | ​ | ​
Total shareholders' equity at December 31, 2023 |  | $ | 5,533,098

Total shareholders' equity at March 31, 2024 | ​ | $ | 5,547,009

The Company repurchased 100,000 shares, at an average price of $79.85 per share for a total of $8.0 million under the 2022 Stock Repurchase Plan during the first quarter of 2024. 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. As of March 31, 2024, a total of 3,920,021 authorized shares remain available for repurchase.

​

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%. Refer to Note 16 — Capital Ratios for more information regarding Company and Bank’s regulatory capital compliance requirements.

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 25% phased out in 2024. At March 31, 2024, approximately $15.3 million was added to Tier 1 capital at the Company and Bank as a result of the modified CECL transition. Had the Company elected not to apply the modified CECL transitional amount to its Tier 1 capital, the Company and Bank would have still been considered well capitalized as of March 31, 2024.

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

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Well-Capitalized | ​ | ​ | March 31, | ​ | ​ | December 31, | ​
​ | ​ | Minimums | ​ | ​ | 2024 | ​ | ​ | 2023 | ​

Tier 1 leverage | ​ | 5.00 | % | ​ | 10.14 | % | ​ | 10.03 | %

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 improved compared to December 31, 2023. All of these ratios mainly improved due to net income recognized during the first quarter of 2024 of $115.1 million. Tier 1 capital increased by 1.1% and 0.5% at both the Company and Bank, respectively, with the increase in equity from the net income recognized. Total risk-based capital increased by 1.1% and 0.7% at both the Company and Bank, respectively, with the increase in equity resulting from net income 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 both the Company and Bank decreasing by 0.6% and risk-based assets decreasing by 0.6%. Our capital ratios are currently 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.

​

The ALCO has established key risk indicators to monitor liquidity and interest rate risk. The key risk indicators are reviewed and approved by the ALCO on an annual basis. The liquidity key risk indicators include the loan to deposit ratio, net noncore funding dependence ratio, On-hand liquidity to total liabilities ratio, the percentage of securities pledged to total securities, and the ratio of brokered deposits to total deposits. As of March 31, 2024, the Company was operating within its liquidity policy limits.

​

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 $618.7 million, or approximately 9.4% annualized, compared to the balance at December 31, 2023. The increase from December 31, 2023 was mainly related to organic growth and renewals of acquired loans that are moved to our non-acquired loan portfolio. The acquired loan portfolio decreased by $339.9 million from the balance at December 31, 2023 through principal paydowns, charge-offs, foreclosures and renewals of acquired loans.

​

Our investment securities portfolio (excluding trading securities) decreased by $231.6 million compared to the balance at December 31, 2023. The decrease in investment securities from December 31, 2023 was a result of maturities, calls, sales and paydowns of investment securities totaling $227.8 million, a reduction from the net amortization of premiums of $4.8 million as well as decrease in the market value of the available for sale investment securities portfolio of $53.6 million. These decreases were partially offset by purchases of other investment securities totaling $54.6 million. There were no purchases of available for sale or held to maturity securities during the quarter. The purchases of other investment securities were related to capital stock with the Federal Home Loan Bank of which we sold back $59.4 million during the first quarter of 2024. The activity in the purchases and sales of the Federal Home Loan Bank Capital Stock was due to activity with FHLB borrowings during the year. The Bank pledges a portion of its investment portfolio for a variety of purposes, including, but not limited to, collateral for public funds and credit with the Federal Home Loan Bank of Atlanta. As of March 31, 2024, the bank pledged 39.5% of the market value of its investment portfolio. As of March 31, 2024, the Bank had unpledged securities with a market value of $4.0 billion. These securities included Treasury, Agency, Agency MBS, Municipals and Corporate securities.

​

Total cash and cash equivalents were $1.2 billion at March 31, 2024 as compared to $1.0 billion at December 31, 2023. Liquidity has tightened starting in 2023 with the rising rate environment and turmoil in the financial markets occurring in early 2023. Competition for in-market deposits has increased throughout 2023 and 2024 resulting in increases in deposit rates to retain local deposits. The Bank supplements its in-market deposits with brokered deposits. While the Bank has a policy limit for brokered time deposits of no more than 15% of total deposits, it has operated well below this policy limit. At March 31, 2024, the percentage of brokered time deposits to total deposits was 2.0% compared to 1.9% at December 31, 2023. During the first quarter of 2024, the Company also borrowed funds from the FHLB on a short-term basis; however, no FHLB advances were outstanding at March 31, 2024. The outstanding borrowings from the FHLB were $100.0 million at December 31, 2023. See below for further discussion around brokered deposits and FHLB borrowings.

​

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.

​

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. Of the $37.2 billion in total deposits at March 31, 2024, approximately 70% were insured or collateralized. The Bank has a granular deposit base comprised of over 1.4 million accounts, with an average deposit size of $27,000. The top ten and twenty deposit relationships comprise approximately 2% and 4% of total deposits, and approximately 28% of total deposits are non-interest bearing. The Bank’s deposit beta, which represents the change in the Bank’s cost of deposits over the change in the federal funds target rate, during this cycle (from March 2022 through March 2024) is approximately 33%.

At March 31, 2024 and December 31, 2023, we had $728.8 million and $719.7 million of traditional, out–of–market brokered time deposits, respectively. At March 31, 2024 and December 31, 2023, we had $2.3 billion and $2.2 billion, respectively, of reciprocal brokered deposits. Total deposits were $37.2 billion at March 31, 2024, an increase of $129.5 million from $37.0 billion at December 31, 2023. This increase in deposits from December 31, 2023 was driven by an increase in money market accounts of $356.7 million, including $167.1 million in reciprocal insured money market deposits along with a $30.6 million increase in time deposits. These increases were partially offset by declines in noninterest-bearing deposits of $102.9 million, interest-bearing checking deposits of $80.0 million and savings deposits of $75.0 million. As customers moved funds from noninterest-bearing deposits, interest-bearing checking and savings accounts, seeking higher yields in the rising rate environment, the Company has seen an increase in its balance of higher yielding money market accounts and time deposits during the first quarter of 2024. The Company raised interest rates on most interest-bearing deposit products (in particular money market accounts and time deposit specials) due to competitive pressures to retain deposits.

​

Total short-term borrowings at March 31, 2024 were $554.7 million, consisting of $273.4 million in federal funds purchased and $281.3 million in securities sold under agreements to repurchase. Total long-term borrowing at March 31, 2024 were $391.8 million and consisted of trust preferred securities and subordinated debentures. 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.

​

In addition to deposits, we have other contingency funding sources available to the Bank. At March 31, 2024, our Bank had a total FHLB credit facility of $6.6 billion, with $2.9 million in FHLB letters of credit outstanding at quarter-end, leaving $6.6 billion in availability on the FHLB credit facility. In addition, our Bank had $1.8 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 $5.6 billion as of March 31, 2024. The Bank had $728.8 million of outstanding brokered deposits at the end of the quarter leaving $4.8 billion in available capacity. All of these resources provide $13.5 billion of additional funding for the Bank. In addition, the Bank has $3.1 billion in market value of unpledged securities at March 31, 2024 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 March 31, 2024. We believe that our liquidity position continues to be adequate and readily available.

​

As discussed previously and presented below, the Bank maintains credit facilities with the Federal Home Loan Bank of Atlanta and the Federal Reserve Bank of Atlanta. The table below compares Primary Funding Sources to uninsured deposits as of March 31, 2024.

In addition to adequate liquidity, the Company and Bank are considered well capitalized by all regulatory capital standards as the Company and the Bank were significantly above the required capital levels as of March 31, 2024. The Company’s tier 1 leverage ratio, CET 1 risk-based capital ratio and total risk-based capital ratio were 9.58%, 11.95% and 14.39%, respectively, at March 31, 2024. The Bank’s Tier 1 leverage ratio, CET 1 risk-based capital ratio and total risk-based capital ratio were 10.14%, 12.66% and 13.99%, respectively, at March 31, 2024. 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 March 31, 2024 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.

Table of Contents

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 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. As noted previously, 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. The assumptions for loan prepayments, deposit decay, and nonstable deposit balances are derived from models that use historical bank data. These models are independently validated. 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. While the Bank is continuously refining its modeling methodology, the core principles of the methodology have remained stable over the past two years.

​

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 consider 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 15 — 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 March 31, 2024, 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 15 — 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. As of March 31, 2024, the Company was operating within its interest rate key risk indicator policy limits.

​

During 2023 and the first quarter of 2024, 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 and seventy-four basis points. During this period, the federal funds rate has increased 525 basis points. Accordingly, our cycle to date beta has been approximately 33%. Management recognizes the difficulty in using historical data to forecast deposit betas in the current environment. For internal purposes, and based on the deposit mix as of March 31, 2024, the total deposit beta assumption was 35.0%. For internal forecasting, management will apply overlays to certain assumptions to adjust for current market conditions rather than use assumptions modeled over longer periods of time.

The following interest rate risk metrics are derived from analysis using the Moody’s Baseline Scenario published in April 2024 as the Base Case Scenario. As of March 31, 2024, the earnings simulations indicated that the year 1 impact of an instantaneous 100 basis point parallel increase / decrease in rates would result in an estimated 1.1% increase (up 100) and 1.8% 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 March 31, 2024, the percentage change in EVE due to a 100-basis point increase or decrease in interest rates was 2.4% decrease and 0.7% increase, respectively. The percentage changes in EVE due to a 200-basis point increase or decrease in interest rates were 5.9% decrease and 0.4% 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 March 31, 2024.

​

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. Base Case assumes new and repricing volumes reference forward rates derived from the Moody’s Baseline rate forecast. Instantaneous, parallel, and sustained interest rate shocks are applied to the Base Case scenario over a one-year time horizon.

Up 200 basis points | ​ | 1.8 | % | ​

Down 400 basis points | ​ | (13.2) | % | ​

Deposit Concentrations

At March 31, 2024 and December 31, 2023, we have no material concentration of deposits from any single customer or group of customers. We have no significant portion of our deposits concentrated within a single industry or group of related industries. We do not believe there are any material seasonal factors that would have a material adverse effect on us. The total deposit balances held by top 10 and 20 deposit holders were below 5% of the Company’s average total deposit balances at March 31, 2024. We do not have any foreign 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 $1.2 billion at March 31, 2024. Based on this criteria, we had eight such credit concentrations at March 31, 2024, including loans to lessors of nonresidential buildings (except mini-warehouses) of $6.1 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 $2.5 billion, loans secured by 1st mortgage 1-4 family owner occupied residential property (including condos and home equity lines) of $9.0 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.

Table of Contents

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 March 31, 2024 and December 31, 2023, the Bank’s CDL concentration ratio was 48.9% and 59.7%, respectively, and its CRE concentration ratio was 235.1% and 236.5%, respectively. As of March 31, 2024, 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.

Reconciliation 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.

PART II — OTHER INFORMATION

​

Item 1. LEGAL PROCEEDINGS

​

On February 9, 2024, the Company disclosed that it detected what was determined to be a cybersecurity incident on February 6, 2024 (the “Cyber Incident”). The Bank notified banking regulators and law enforcement and, based on its investigation and findings, notified individuals whose personal information may have been compromised in the Cyber Incident. Further, the Bank has taken other actions, such as offering credit monitoring services. While the Company is unable to estimate the total cost of any remediation that may be required, as of March 31, 2024, the Company had not incurred material costs as a result of the Cyber Incident.

​

On April 3, 2024, a putative class action lawsuit (the “Original Suit”) was filed against the Bank purportedly on behalf of a class consisting of those persons impacted by the Cyber Incident. As of the date of this Quarterly Report on Form 10-Q, 14 putative class action lawsuits, including the Original Suit, are pending. For more information about the Original Suit and other litigations filed in connection with the Cyber Incident, please refer to Note 12 — Commitments and Contingent Liabilities, in the Notes to Condensed Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q.

​

Other than the Cyber Incident Suits (as defined in Note 12 — Commitments and Contingent Liabilities), as of March 31, 2024, and the date of this Quarterly Report on Form 10-Q, we believe that we are not party to, nor is any of our property the subject of, any pending material legal proceeding other than those that may occur in the ordinary course of our business.
