GREAT SOUTHERN BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1: BASIS OF PRESENTATION

The accompanying unaudited interim consolidated financial statements of Great Southern Bancorp, Inc. (the “Company” or “Great Southern”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. The financial statements presented herein reflect all adjustments which are, in the opinion of management, necessary to fairly present the financial condition, results of operations, changes in stockholders’ equity and cash flows of the Company as of the dates and for the periods presented. Those adjustments consist only of normal recurring adjustments. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the full year. The consolidated statement of financial condition of the Company as of December 31, 2023, has been derived from the audited consolidated statement of financial condition of the Company as of that date.

Certain information and note disclosures normally included in the Company’s annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted. These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 filed with the Securities and Exchange Commission (the “SEC”).

Reclassifications

Prior period consolidated financial statements are reclassified whenever necessary to conform to the current period presentation.

Correction of an Immaterial Error in Prior Period Financial Statements

Certain prior period amounts in the Consolidated Statements of Cash Flows have been corrected as discussed below. No other financial statements or notes thereto were impacted by these corrections.

The Company has corrected its Consolidated Statements of Cash Flows for the six months ended June 30, 2023 within this Quarterly Report on Form 10-Q for an error in classification within the operating activities section of the statements of cash flows regarding amortization of terminated hedging transactions and for an error in classification regarding investments in tax credit partnerships between the operating activities and investing activities sections of the statements of cash flows.

For the item related to the terminated hedging transactions, the Company is now including the amortization from accumulated other comprehensive income and related deferred taxes recognized in interest income as an item not providing cash in accretion of deferred income, premiums, discounts and other. This was previously included in net changes in prepaid expenses and other assets. For the item related to investments in tax credit partnerships, the Company is now including the amounts invested as an item using cash in the investing activities section. This was previously included in net changes in prepaid expenses and other assets in the operating activities section.

The Company assessed the materiality of this change in presentation on prior period consolidated financial statements in accordance with SEC Staff Accounting Bulletin No. 99, “Materiality,” (ASC Topic 250, Accounting Changes and Error Corrections). Based on this assessment, the Company concluded that these error corrections in its statements of cash flows are not material to any previously presented financial statements. The corrections had no impact on the Consolidated Statements of Financial Condition, Consolidated Statements of Income, Consolidated Statements of Comprehensive Income or Consolidated Statements of Stockholders’ Equity, or notes to these financial statements, for any previously presented interim or annual financial statements. Accordingly, the Company corrected the previously reported immaterial errors for the six months ended June 30, 2023 in this Quarterly Report on Form 10-Q.

NOTE 2: NATURE OF OPERATIONS AND OPERATING SEGMENTS

The Company operates as a one-bank holding company. The Company’s business primarily consists of the operations of Great Southern Bank (the “Bank”), which provides a full range of financial services to customers primarily located in Missouri, Iowa, Kansas, Minnesota, Nebraska and Arkansas. The Bank also originates commercial loans from lending offices in Atlanta; Charlotte, North Carolina; Chicago; Dallas; Denver; Omaha, Nebraska; and Phoenix. The Company and the Bank are subject to regulation by certain federal and state agencies and undergo periodic examinations by those regulatory agencies.

The Company’s banking operation is its only reportable segment. The banking operation is principally engaged in the business of originating residential and commercial real estate loans, construction loans, commercial business loans and consumer loans and funding these loans by attracting deposits from the general public, accepting brokered deposits and borrowing from the Federal Home Loan Bank and others. The operating results of this segment are regularly reviewed by management to make decisions about resource allocations and to assess performance. Selected information is not presented separately for the Company’s reportable segment, as there is no material difference between that information and the corresponding information in the consolidated financial statements.

​

NOTE 3: RECENT ACCOUNTING PRONOUNCEMENTS

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. ASU 2020-04 provides relief for companies preparing for discontinuation of interest rates such as the London Interbank Offered Rate (“LIBOR”). LIBOR is a benchmark interest rate referenced in a variety of agreements that are used by numerous entities. After 2021, certain LIBOR rates may no longer be published. As a result, LIBOR is expected to be discontinued as a reference rate. Other interest rates used globally could also be discontinued for similar reasons. ASU 2020-04 provides optional expedients and exceptions to contracts, hedging relationships and other transactions affected by reference rate reform. The main provisions for contract modifications include optional relief by allowing the modification as a continuation of the existing contract without additional analysis and other optional expedients regarding embedded features. Optional expedients for hedge accounting permit changes to critical terms of hedging relationships and to the designated benchmark interest rate in a fair value hedge and provide relief for assessing hedge effectiveness for cash flow hedges. ASU 2020-04 was effective upon issuance; however, the guidance was originally only available generally through December 31, 2022. Based upon amendments provided in ASU 2022-06 discussed below, provisions of ASU 2020-04 can now generally be applied through December 31, 2024. The application of ASU 2020-04 has not had, and is not expected to have, a material impact on the Company’s consolidated financial statements.

In January 2021, the FASB issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope. ASU 2021-01 clarifies that certain optional expedients and exceptions in ASC 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. ASU 2021-01 also amends the expedients and exceptions in ASC 848 to capture the incremental consequences of the scope clarification and to tailor the existing guidance to derivative instruments affected by the discounting transition. ASU 2021-01 was effective upon issuance; however, the guidance was originally only available generally through December 31, 2022. Based upon amendments provided in ASU 2022-06 discussed below, provisions of ASU 2021-01 can now generally be applied through December 31, 2024. ASU 2021-01 has not had, and is not expected to have, a material impact on the Company’s consolidated financial statements.

​

In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. ASU 2022-06 extends the period of time entities can utilize the reference rate reform relief guidance provided by ASU 2020-04 and ASU 2021-01, which are discussed above. ASU 2022-06 was effective upon issuance and defers the sunset date of this prior guidance to December 31, 2024, after which entities will no longer be permitted to apply the relief guidance in Topic 848. ASU 2022-06 has not had, and is not expected to have, a material impact on the Company’s consolidated financial statements.

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. ASU 2023-02 is intended to improve the accounting and disclosures for investments in tax credit structures. ASU 2023-02 allows entities to elect to account for qualifying tax equity investments using the proportional amortization method, regardless of the program giving rise to the related income tax credits. Previously, this method was only available for qualifying tax equity investments in low-income housing tax credit structures. Currently, the Company does not have a material amount of tax credit structures, other than low-income housing tax credit structures. ASU 2023-02 became effective for the Company on January 1, 2024. The adoption of ASU 2023-02 did not have a material impact on the Company’s consolidated financial statements and resulted in a reduction of retained earnings of $223,000 upon adoption on January 1, 2024.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. ASU 2023-07 expands reportable segment disclosure requirements through enhanced disclosures about significant segment expenses. ASU 2023-07 implements a new requirement to disclose significant segment expenses regularly provided to the chief operating decision maker, expands certain annual disclosures to interim periods, clarifies that single reportable segment entities must apply Topic 280 in its entirety and permits more than one measure of segment profit or loss to be reported under certain conditions. ASU 2023-07 is effective for the Company for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the requirements of the expanded segment disclosures but does not currently expect the additional disclosures to have a material impact on the Company’s consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 is focused on additional income tax disclosures and requires public business entities, on an annual basis, to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income by the applicable statutory income tax rate). ASU 2023-09 is effective for the Company for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2024, with early adoption permitted. While the Company is currently assessing the impact applying this standard will have on its income tax disclosures, the adoption of ASU 2023-09 is not expected to have a material impact on the Company’s consolidated financial statements.

NOTE 5: INVESTMENT SECURITIES

Held-to-maturity securities (“HTM”), which include any security for which the Company has both the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Premiums and discounts are amortized and accreted, respectively, to interest income over the security’s estimated life. Prepayments are anticipated for certain mortgage-backed securities. Premiums on callable securities are amortized to their earliest call date.

Available-for-sale securities (“AFS”), which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Realized gains and losses, based on specifically identified amortized cost of the individual security, are included in non-interest income. Unrealized gains and losses are recorded, net of related income tax effects, in stockholders’ equity. Premiums and discounts are amortized and accreted, respectively, to interest income over the estimated life of the security. Prepayments are anticipated for certain mortgage-backed and Small Business Administration (SBA) securities. Premiums on callable securities are amortized to their earliest call date.

The amortized cost and fair values of securities were as follows:

Certain available-for-sale investments in debt securities are reported in the financial statements at an amount less than their amortized cost. Total fair value of these investments at June 30, 2024 and December 31, 2023, was approximately $533.5 million and $456.9 million, respectively, which was approximately 97.2% and 95.5% of the Company’s total available-for-sale investment portfolio at those dates. A high percentage of the unrealized losses were related to the Company’s mortgage-backed securities, collateralized mortgage obligations and Small Business Administration (SBA) securities, which are issued and guaranteed by U.S. government-sponsored entities and agencies. The Company’s state and political subdivisions securities are investments in insured fixed rate municipal bonds for which the issuers continue to make timely principal and interest payments under the contractual terms of the securities. Held-to-maturity investments in debt securities are reported in the financial statements at their amortized carrying value at

​

June 30, 2024 and December 31, 2023, which was $191.2 million and $195.0 million, respectively. Total fair value of these investments at June 30, 2024 and December 31, 2023 was approximately $165.2 million and $171.2 million, respectively. Held-to-maturity investment securities are evaluated for potential credit losses under ASU 2016-13. The Company continually assesses its liquidity sources, both on-balance sheet and off-balance sheet, and believes that at June 30, 2024, it had ample liquidity sources to fund its ongoing operations.

Based on evaluation of available evidence, including recent changes in market interest rates, credit rating information and information obtained from regulatory filings of issuers, management believes the declines in fair value for these available-for-sale debt securities are not credit-related.

The following table shows the Company’s available-for-sale and held-to-maturity securities’ gross unrealized losses and fair values, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2024 and December 31, 2023:

Allowance for Credit Losses. On January 1, 2021, the Company began evaluating all securities quarterly to determine if any securities in a loss position require a provision for credit losses in accordance with ASC 326, Measurement of Credit Losses on Financial Instruments. All of the mortgage-backed, collateralized mortgage, and SBA securities held by the Company as of June 30, 2024 were issued by U.S. government-sponsored entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. Likewise, the Company has not historically experienced losses on these types of securities. Accordingly, no allowance for credit losses has been recorded for these securities.

Regarding securities issued by state and political subdivisions, management considers the following when evaluating these securities: (i) current issuer bond ratings, (ii) historical loss rates for given bond ratings, (iii) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities, (iv) updated financial information of the issuer, (v) internal forecasts and (vi) whether such securities provide insurance or other credit enhancement or are pre-refunded by the issuers. These securities are generally highly rated by major rating agencies and have a long history of no credit losses. Likewise, the Company has not historically experienced losses on these types of securities. Accordingly, no allowance for credit losses has been recorded for these securities.

​

NOTE 6: LOANS AND ALLOWANCE FOR CREDIT LOSSES

The allowance for credit losses is measured using an average historical loss model that incorporates relevant information about past events (including historical credit loss experience on loans with similar risk characteristics), current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the loans. The allowance for credit losses is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics, including borrower type, collateral and repayment types and expected credit loss patterns. Loans that do not share similar risk characteristics, primarily classified loans with balances greater than or equal to $100,000, are evaluated on an individual basis.

For loans evaluated for credit losses on a collective basis, average historical loss rates are calculated for each pool using the Company’s historical net charge-offs (combined charge-offs and recoveries by observable historical reporting period) and outstanding loan balances during a lookback period. Lookback periods can be different based on the individual pool and reflect management’s credit expectations for the pool of loans over the remaining contractual life. In certain loan pools, if the Company’s own historical loss rate is not reflective of the loss expectations, the historical loss rate is augmented by industry and peer data. The calculated average net charge-off rate is then adjusted for current conditions and reasonable and supportable forecasts. These adjustments increase or decrease the average historical loss rate to reflect expectations of future losses given economic forecasts of key macroeconomic variables including, but not limited to, unemployment rate, gross domestic product (“GDP”), commercial real estate price index, consumer sentiment and construction spending. The adjustments are based on results from various regression models projecting the impact of the macroeconomic variables to loss rates. The forecast is used for a reasonable and supportable period before reverting to historical averages. The forecast-adjusted loss rate is applied to the principal balance over the remaining contractual lives, adjusted for expected prepayments. The contractual term excludes expected extensions, renewals and modifications. Additionally, the allowance for credit losses considers other qualitative factors not included in historical loss rates or macroeconomic forecasts such as changes in portfolio composition, underwriting practices, or significant unique events or conditions.

In addition, the Company is required to record an allowance for off balance sheet credit exposures, including unfunded lines of credit, undisbursed portions of loans, written residential and commercial loan commitments, and letters of credit. To determine the amount needed for allowance purposes, a utilization rate is determined either by the model or internally for each pool. Our loss model calculates the reserve on unfunded commitments based upon the utilization rate multiplied by the average loss rate factors in each pool with unfunded and committed balances. The liability for unfunded lending commitments utilizes the same model as the allowance for credit losses on loans; however, the liability for unfunded lending commitments incorporates assumptions for the portion of unfunded commitments that are expected to be funded.

Loans are placed on nonaccrual status at 90 days past due and interest is considered a loss unless the loan is well secured and in the process of collection. Payments received on nonaccrual loans are applied to principal until the loans are returned to accrual status. Loans are returned to accrual status when all payments contractually due are brought current, payment performance is sustained for a period of time, generally six months, and future payments are reasonably assured. With the exception of consumer loans, charge-offs on loans are recorded when available information indicates a loan is not fully collectible and the loss is reasonably quantifiable. Consumer loans are charged-off at specified delinquency dates consistent with regulatory guidelines.

Non-accruing loans are summarized as follows:

No interest income was recorded on nonaccrual loans for the three or six months ended June 30, 2024 and 2023, respectively.

Nonaccrual loans for which there is no related allowance for credit losses as of June 30, 2024 and December 31, 2023, had an amortized cost of $2.4 million and $792,000, respectively. These loans are individually assessed and do not require an allowance due to being adequately collateralized under the collateral-dependent valuation method. A collateral-dependent loan is a financial asset for which the repayment is expected to be provided substantially through the operation or sale of the collateral when the borrower is experiencing financial difficulty based on the Company’s assessment as of the reporting date. Collateral-dependent loans are identified primarily by a classified risk rating with a loan balance equal to or greater than $100,000, including, but not limited to, any loan in process of foreclosure or repossession.

The following tables present the activity in the allowance for credit losses by portfolio segment for the three and six months ended June 30, 2024 and 2023. During the three months ended June 30, 2024, the Company did not record a provision expense on its portfolio of outstanding loans and during the six months ended June 30, 2024, recorded provision expense of $500,000 on its portfolio of outstanding loans. During the three months ended June 30, 2023, the Company did not record a provision expense on its portfolio of outstanding loans and during the six months ended June 30, 2023, recorded provision expense of $1.5 million on its portfolio of outstanding loans.

Modified Loans. In March 2022, the FASB issued ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures. ASU 2022-02 eliminates the troubled debt restructuring (TDR) recognition and measurement guidance and, instead, requires that an entity evaluate whether the loan modification represents a new loan or a continuation of an existing loan. It also enhances disclosure requirements and introduces new disclosure requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. Adoption of this ASU on January 1, 2023 did not have a material impact on the Company’s results of operations, financial position or liquidity, but resulted in additional disclosure requirements related to gross charge offs by vintage year and the removal of TDR disclosures, replaced by additional disclosures on the types of modifications of loans to borrowers experiencing financial difficulties. The Company has adopted this update prospectively. Loan modifications are reported if concessions have been granted to borrowers that are experiencing financial difficulty.

The estimate of lifetime expected losses utilized in the allowance for credit losses model is developed using average historical loss on loans with similar risk characteristics, which includes losses from modifications of loans to borrowers experiencing financial difficulty. As a result, a charge to the allowance for credit losses is generally not recorded upon modification. For modifications to loans made to borrowers experiencing financial difficulty that are adversely classified, the Company determines the allowance for credit losses on an individual basis, using the same process that it utilizes for other adversely classified loans. If collection efforts have begun and the modified loan is subsequently deemed collateral-dependent, the loan is placed on non-accrual status and the allowance for credit losses is determined based on an individual evaluation. If necessary, the loan is charged down to fair market value less estimated sales costs.

​

The following tables show, as of the dates indicated, the composition of modifications made to loans to borrowers experiencing financial difficulty, by loan class and type of concession granted. Each of the types of concessions granted comprised 1.0% or less of their respective loan classes at June 30, 2024. During the three and six months ended June 30, 2024, principal forgiveness of $241,000 and $255,000, respectively, was completed on consumer loans and a land development loan. During the three and six months ended June 30, 2023, principal forgiveness of $6,000 and $39,000, respectively, was completed on consumer loans.

Loan Risk Ratings. The Company utilizes an internal risk rating system comprised of a series of grades to categorize loans according to perceived risk associated with the expectation of debt repayment. The analysis of the borrower’s ability to repay considers specific

20

​

information, including but not limited to current financial information, historical payment experience, industry information and collateral levels and types. A risk rating is assigned at loan origination and then monitored throughout the contractual term for possible risk rating changes.

Satisfactory loans range from Excellent to Moderate Risk, but generally are loans supported by strong recent financial statements. The character and capacity of the borrower are solid, including reasonable project performance, good industry experience, liquidity and/or net worth. The probability of financial deterioration seems unlikely. Repayment is expected from approved sources over a reasonable period of time.

Watch loans are identified when the borrower has capacity to perform according to terms; however, elements of uncertainty exist. Margins of debt service coverage may be narrow, historical patterns of financial performance may be erratic, collateral margins may be diminished or the borrower may be a new and/or thinly capitalized company. Some management weakness may also exist, the borrower may have somewhat limited access to other financial institutions, and that access may diminish in difficult economic times.

Special Mention loans have weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of repayment prospects or the Bank’s credit position at some future date. This is a transitional grade closely monitored for improvement or deterioration.

The Substandard rating is applied to loans where the borrower exhibits well-defined weaknesses that jeopardize its continued performance and are of a severity that the distinct possibility of default exists. Loans are placed on “non-accrual” when management does not expect to collect payments consistent with acceptable and agreed upon terms of repayment.

Doubtful loans have all the weaknesses inherent to those classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, highly questionable and improbable.

The Loss category is used when loans are considered uncollectable and no longer included as an asset.

All loans are analyzed for risk rating updates regularly. For larger loans, rating assessments may be more frequent if relevant information is obtained earlier through debt covenant monitoring or overall relationship management. Smaller loans are monitored as identified by the loan officer based on the risk profile of the individual borrower or if the loan becomes past due related to credit issues. Loans rated Watch, Special Mention, Substandard or Doubtful are subject to formal quarterly review and continuous monitoring processes. In addition to the regular monitoring performed by the lending personnel and credit committees, loans are subject to review by the credit review department, which verifies the appropriateness of the risk ratings for the loans chosen as part of its risk-based review plan.

NOTE 7: INVESTMENTS IN LIMITED PARTNERSHIPS

Investments in Affordable Housing Partnerships

From time to time, the Company has invested in certain limited partnerships that were formed to develop and operate apartments and single-family houses designed as high-quality affordable housing for lower income tenants throughout Missouri and contiguous states. At June 30, 2024, the Company had 22 such investments, with a net carrying value of $103.1 million. At December 31, 2023, the Company had 22 such investments, with a net carrying value of $66.3 million. Due to the Company’s inability to exercise any significant influence over any of the investments in Affordable Housing Partnerships, they all are accounted for using the proportional amortization method. Each of the partnerships must meet the regulatory requirements for affordable housing for a minimum 15-year compliance period to fully utilize the tax credits. If the partnerships cease to qualify during the compliance period, the credits may be denied for any period in which the projects are not in compliance and a portion of the credits previously taken may be subject to recapture with interest.

The remaining federal affordable housing tax credits to be utilized through 2034 were $111.7 million as of June 30, 2024, assuming no tax credit recapture events occur and all projects currently under construction are completed as planned. Amortization of the investments in partnerships is expected to be approximately $100.8 million, assuming all projects currently under construction are completed and funded as planned.

The Company’s usage of federal affordable housing tax credits approximated $2.8 million and $1.9 million during the three months ended June 30, 2024 and June 30, 2023, respectively. Investment amortization was $2.5 million for the three months ended June 30, 2024, compared to $1.7 million for the three months ended June 30, 2023.

The Company’s usage of federal affordable housing tax credits approximated $5.6 million and $3.8 million during the six months ended June 30, 2024 and June 30, 2023, respectively. Investment amortization was $5.1 million for the six months ended June 30, 2024, compared to $3.5 million for the six months ended June 30, 2023.

Investments in Community Development Entities

From time to time, the Company has invested in certain limited partnerships that were formed to develop and operate business and real estate projects located in low-income communities. At June 30, 2024, the Company had one such investment, with a net carrying value of $249,000. At December 31, 2023, the Company had one such investment, with a net carrying value of $361,000. Due to the Company’s inability to exercise any significant influence over any of the investments in qualified Community Development Entities, they are all accounted for using the proportional amortization method. Each of the partnerships provides federal New Market Tax Credits over a seven-year credit allowance period. In each of the first three years, credits totaling five percent of the original investment are allowed on the credit allowance dates, and for the final four years, credits totaling six percent of the original investment are allowed on the credit allowance dates. Each of the partnerships must be invested in a qualified Community Development Entity on each of the credit allowance dates during the seven-year period to utilize the tax credits. If the Community Development Entities cease to qualify during the seven-year period, the credits may be denied for any credit allowance date and a portion of the credits previously taken may be subject to recapture with interest. The investments in the Community Development Entities cannot be redeemed before the end of the seven-year period.

The Company’s usage of federal New Market Tax Credits approximated $30,000 and $25,000 during the three months ended June 30, 2024 and 2023, respectively. Investment amortization amounted to $25,000 and $21,000 for the three months ended June 30, 2024 and 2023, respectively. The Company’s usage of federal New Market Tax Credits approximated $60,000 and $50,000 during the six months ended June 30, 2024 and 2023, respectively. Investment amortization amounted to $25,000 and $42,000 for the six months ended June 30, 2024 and 2023, respectively. Upon adoption of ASU 2023-02 on January 1, 2024, the Company recorded a reduction in the investment in these New Market Tax Credits, with a corresponding reduction in retained earnings, of $62,000.

Investments in Limited Partnerships for Federal Rehabilitation/Historic Tax Credits

From time to time, the Company has invested in certain limited partnerships that were formed to provide certain federal rehabilitation/historic tax credits. At June 30, 2024, the Company had one such investment, with a net carrying value of $127,000. At December 31, 2023, the Company had one such investment, with a net carrying value of $415,000. Under prior tax law, the Company utilized these credits in their entirety in the year the project was placed in service and the impact to the Consolidated Statements of Income has not been material. Currently, such partnerships provide federal rehabilitation/historic tax credits over a five-year credit allowance period.

Leases. In 2019, the Company adopted ASU 2016-02, Leases (Topic 842). Adoption of this ASU resulted in the Company initially recognizing a right of use asset and corresponding lease liability of $9.5 million. The amount of the right of use asset and corresponding lease liability will fluctuate based on the Company’s lease terminations, new leases and lease modifications and renewals. As of June 30, 2024, the lease right of use asset value was $6.9 million and the corresponding lease liability was $7.1 million. As of December 31, 2023, the lease right of use asset value was $6.6 million and the corresponding lease liability was $6.9 million. At June 30, 2024, expected lease terms ranged from 3.1 years to 14.4 years with a weighted-average lease term of 7.2 years. The weighted-average discount rate at June 30, 2024 was 4.02%.

For the three months ended June 30, 2024 and 2023, lease expense was $413,000 and $433,000, respectively. For the six months ended June 30, 2024 and 2023, lease expense was $895,000 and $843,000, respectively. The Company’s short-term leases related to offsite ATMs have both fixed and variable lease payment components, based on the number of transactions at the various ATMs. The variable portion of these lease payments is not material. The total lease expense related to ATMs for the three months ended June 30, 2024 and 2023 was $90,000 and $78,000, respectively. The total lease expense related to ATMs for the six months ended June 30, 2024 and 2023 was $171,000 and $150,000, respectively.

The Company does not sublease any of its leased facilities; however, it does lease to other parties portions of facilities that it owns. In terms of being the lessor in these circumstances, all of these lease agreements are classified as operating leases. In the three months ended June 30, 2024 and 2023, income recognized from these lease agreements was $339,000 and $325,000, respectively, and was included in occupancy and equipment expense. In the six months ended June 30, 2024 and 2023, income recognized from these lease agreements was $680,000 and $649,000, respectively, and was included in occupancy and equipment expense.

​

Borrowings from the Federal Reserve Bank at June 30, 2024, were part of the Federal Reserve Bank’s Bank Term Funding Program (BTFP). The BTFP borrowing, which matures in January 2025 and has a fixed interest rate of 4.83%, may be repaid in full or in part without penalty prior to its stated maturity date. The line is secured primarily by the Bank’s held-to-maturity investment securities, with assets pledged totaling approximately $191.3 million as of June 30, 2024.

The Bank enters into sales of securities under agreements to repurchase (reverse repurchase agreements). Reverse repurchase agreements are treated as financings, and the obligations to repurchase securities sold are reflected as a liability in the statements of financial condition. The dollar amount of securities underlying the agreements remains in the asset accounts. Securities underlying the agreements are held by the Bank during the agreement period. All agreements are written on a term of one month or less.

The following table reflects the Company’s securities sold under reverse repurchase agreements, by collateral type. These securities contractually mature daily.

NOTE 13: SUBORDINATED NOTES

On June 10, 2020, the Company completed the public offering and sale of $75.0 million of its subordinated notes. The notes are due June 15, 2030, and have a fixed interest rate of 5.50% until June 15, 2025, at which time the rate becomes floating at a rate expected to be equal to three-month term Secured Overnight Financing Rate (SOFR) plus 5.325%. The Company may call the notes at par beginning on June 15, 2025, and on any scheduled interest payment date thereafter. The notes were sold at par, resulting in net proceeds, after underwriting discounts and commissions, legal, accounting and other professional fees, of approximately $73.5 million. Total debt issuance costs of approximately $1.5 million were deferred and are being amortized over the expected life of the notes, which is five years.

Amortization of the debt issuance costs during the three months ended June 30, 2024 and 2023, totaled $74,000 and $75,000, respectively. Amortization of the debt issuance costs during the six months ended June 30, 2024 and 2023, totaled $148,000 and $149,000, respectively. Amortization of the debt issuance costs is included in interest expense on subordinated notes in the consolidated statements of income, resulting in an imputed interest rate of 5.91%.

The Company and its consolidated subsidiaries have not been audited recently by the Internal Revenue Service (IRS). As a result, federal tax years through December 31, 2019 are now closed. In addition, there are no pending audits by any state jurisdiction at June 30, 2024.

​

The Company was previously under State of Missouri income and franchise tax examinations for its 2014 and 2015 tax years. The examinations concluded with one unresolved issue related to the exclusion of certain income in the calculation of Missouri income tax. The Missouri Department of Revenue denied the Company’s administrative protest regarding the 2014 and 2015 tax years’ examinations. In June 2021, the Company filed a formal protest with the Missouri Administrative Hearing Commission (MAHC), which has special jurisdiction to hear tax matters and is similar to a trial court, to continue defending the Company’s rights and associated tax position. The Company previously filed a motion for summary decision with the MAHC and, on January 26, 2024, the MAHC granted the motion in favor of the Company, upholding the Company’s position related to the exclusion of certain income from the calculation of Missouri income tax. In February 2024, the Missouri Department of Revenue confirmed to the Company in writing that it would not exercise its right to appeal the decision to the Missouri State Supreme Court.

NOTE 15: DISCLOSURES ABOUT FAIR VALUE OF FINANCIAL INSTRUMENTS

ASC Topic 820, Fair Value Measurements, defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Topic 820 also specifies a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value:

| ● | Quoted prices in active markets for identical assets or liabilities (Level 1): Inputs that are quoted unadjusted prices in active markets for identical assets that the Company has the ability to access at the measurement date. An active market for the asset is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

| ● | Other observable inputs (Level 2): Inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the reporting entity including quoted prices

29

​

|  | for similar assets, quoted prices for securities in inactive markets and inputs derived principally from or corroborated by observable market data by correlation or other means.

| ● | Significant unobservable inputs (Level 3): Inputs that reflect assumptions of a source independent of the reporting entity or the reporting entity’s own assumptions that are supported by little or no market activity or observable inputs.

Financial instruments are broken down by recurring or nonrecurring measurement status. Recurring assets are initially measured at fair value and are required to be remeasured at fair value in the financial statements at each reporting date. Assets measured on a nonrecurring basis are assets that, due to an event or circumstance, were required to be remeasured at fair value after initial recognition in the financial statements at some time during the reporting period.

The Company considers transfers between the levels of the hierarchy to be recognized at the end of related reporting periods.

Recurring Measurements

The following table presents the fair value measurements of assets recognized in the accompanying statements of financial condition measured at fair value on a recurring basis and the level within the fair value hierarchy in which the fair value measurements fell at June 30, 2024 and December 31, 2023:

The following is a description of inputs and valuation methodologies used for assets recorded at fair value on a recurring basis and recognized in the accompanying statements of financial condition at June 30, 2024 and December 31, 2023 as well as the general classification of such assets pursuant to the valuation hierarchy. There were no significant changes in the valuation techniques during the six-month period ended June 30, 2024. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below.

Available-for-Sale Securities. Investment securities available-for-sale are recorded at fair value on a recurring basis. The fair values used by the Company are obtained from an independent pricing service, which represent either quoted market prices for the identical asset or fair values determined by pricing models, or other model-based valuation techniques, that consider observable market data, such as interest rate volatilities, SOFR yield curve, credit spreads and prices from market makers and live trading systems. Recurring Level 2 securities include U.S. government agency securities, mortgage-backed securities, state and municipal bonds and certain other investments. Inputs used for valuing Level 2 securities include observable data that may include dealer quotes, benchmark yields, market spreads, live trading levels and market consensus prepayment speeds, among other things. Additional inputs include indicative

30

​

values derived from the independent pricing service’s proprietary computerized models. There were no recurring Level 3 securities at June 30, 2024 or December 31, 2023.

Interest Rate Derivatives. The fair value is estimated using forward-looking interest rate curves and is determined using observable market rates and, therefore, are classified within Level 2 of the valuation hierarchy.

Nonrecurring Measurements

The following table presents the measurements of assets measured at fair value on a nonrecurring basis and the level within the fair value hierarchy in which the measurements fell at June 30, 2024 and December 31, 2023:

​

The following is a description of valuation methodologies used for assets measured at fair value on a nonrecurring basis and recognized in the accompanying statements of financial condition, as well as the general classification of such assets pursuant to the valuation hierarchy. For assets classified within Level 3 of the fair value hierarchy, the process used to develop the reported fair value is described below.

Loans Held for Sale. Mortgage loans held for sale are recorded at the lower of carrying value or fair value. The fair value of mortgage loans held for sale is based on what secondary markets are currently offering for portfolios with similar characteristics. As such, the Company classifies mortgage loans held for sale as Nonrecurring Level 2. Write-downs to fair value typically do not occur as the Company generally enters into commitments to sell individual mortgage loans at the time the loan is originated to reduce market risk. The Company typically does not have commercial loans held for sale. At June 30, 2024 and December 31, 2023, the aggregate fair value of mortgage loans held for sale was not materially different than their cost. Accordingly, no mortgage loans held for sale were marked down and reported at fair value.

Collateral-Dependent Loans. The Company records collateral-dependent loans as Nonrecurring Level 3. If a loan’s fair value as estimated by the Company is less than its carrying value, the Company either records a charge-off of the portion of the loan that exceeds the fair value or establishes a reserve within the allowance for credit losses specific to the loan. Loans for which such charge-offs or reserves were recorded are shown in the table above (net of reserves) at June 30, 2024 and December 31, 2023.

Foreclosed Assets Held for Sale. Foreclosed assets held for sale are initially recorded at fair value less estimated cost to sell at the date of foreclosure. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated cost to sell. Foreclosed assets held for sale are classified within Level 3 of the fair value hierarchy. There were no foreclosed assets held for sale at June 30, 2024 or December 31, 2023 which had valuation write-downs subsequent to the initial recording of the assets.

Fair Value of Financial Instruments

The following methods were used to estimate the fair value of all other financial instruments recognized in the accompanying statements of financial condition at amounts other than fair value.

Cash and Cash Equivalents and Federal Home Loan Bank Stock. The carrying amount approximates fair value.

Held-to-Maturity Securities. Fair values for held-to-maturity securities are estimated based on quoted market prices of similar securities. For these securities, the Company obtains fair value measurements from an independent pricing service, which represent either quoted market prices for the identical asset or fair values determined by pricing models, or other model-based valuation

31

​

techniques, that consider observable market data, such as interest rate volatilities, SOFR yield curve, credit spreads and prices from market makers and live trading systems. These securities include U.S. government agency securities, mortgage-backed securities, state and municipal bonds and certain other investments.

Loans and Interest Receivable. The fair value of loans is estimated on an exit price basis incorporating contractual cash flows, prepayment discount spreads, credit loss and liquidity premiums. Loans with similar characteristics are aggregated for purposes of the calculations. The carrying amount of accrued interest receivable approximates its fair value.

Deposits and Accrued Interest Payable. The fair value of demand deposits and savings accounts is the amount payable on demand at the reporting date, i.e., their carrying amounts. The fair value of fixed maturity certificates of deposit is estimated based on a discounted cash flow calculation using the average advances yield curve from 11 districts of the FHLB for the as of date. The carrying amount of accrued interest payable approximates its fair value.

Short-Term Borrowings. The carrying amount approximates fair value.

Subordinated Debentures Issued to Capital Trusts. The subordinated debentures have floating rates that reset quarterly. The carrying amount of these debentures approximates their fair value.

Subordinated Notes. The fair values used by the Company are obtained from independent sources and are derived from quoted market prices of the Company’s subordinated notes and quoted market prices of other subordinated debt instruments with similar characteristics.

Commitments to Originate Loans, Letters of Credit and Lines of Credit. The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair value of letters of credit is based on fees currently charged for similar agreements or on the estimated cost to terminate them or otherwise settle the obligations with the counterparties at the reporting date.

​

The following table presents estimated fair values of the Company’s financial instruments not recorded at fair value in the financial statements. The fair values of certain of these instruments were calculated by discounting expected cash flows, which method involves significant judgments by management and uncertainties. Fair value is the estimated amount at which financial assets or liabilities could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Because no market exists for certain of these financial instruments and because management does not intend to sell these financial instruments, the Company does not know whether the fair values shown below represent values at which the respective financial instruments could be sold individually or in the aggregate.

NOTE 16: DERIVATIVES AND HEDGING ACTIVITIES

Risk Management Objective of Using Derivatives

The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources and duration of its assets and liabilities. In the normal course of business, the Company may use derivative financial instruments (primarily interest rate swaps) from time to time to assist in its interest rate risk management. The Company has interest rate derivatives that result from a service provided to certain qualifying loan customers that are not used to manage interest rate risk in the Company’s assets or liabilities and are not designated in a qualifying hedging relationship. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. In addition, the Company has interest rate derivatives that have been designated in a qualified hedging relationship.

Nondesignated Hedges

The Company has interest rate swaps that are not designated in a qualifying hedging relationship. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain loan customers. The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. 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.

33

​

At June 30, 2024, the Company had five interest rate swaps totaling $75.4 million in notional amount with commercial customers, and five interest rate swaps with the same aggregate notional amount with third parties related to its program. In addition, the Company has one participation loan purchased totaling $8.5 million, in which the lead institution has an interest rate swap with its customer and the economics of the counterparty swap are passed along to the Company through the loan participation. At December 31, 2023, the Company had six interest rate swaps totaling $82.2 million in notional amount with commercial customers, and six interest rate swaps with the same notional amount with third parties related to its program. In addition, at December 31, 2023, the Company had one participation loan purchased totaling $8.6 million, in which the lead institution has an interest rate swap with its customer and the economics of the counterparty swap are passed along to the Company through the loan participation. During the three months ended June 30, 2024 and 2023, the Company recognized a net loss of $7,000 and a net gain of $2,000, respectively, in non-interest income related to changes in the fair value of these swaps. During the six months ended June 30, 2024 and 2023, the Company recognized net losses of $20,000 and $289,000, respectively, in non-interest income related to changes in the fair value of these swaps.

Fair Value Hedges

Interest Rate Swaps. As a strategy to maintain acceptable levels of exposure to the risk of changes in future cash flows due to interest rate fluctuations, in February 2023, the Company entered into interest rate swap transactions as part of its ongoing interest rate management strategies to hedge the risk of certain of its fixed rate brokered deposits. The total notional amount of the swaps was $95 million with a termination date of February 28, 2025. Under the terms of the swaps, the Company received a fixed rate of interest of 4.65% and paid a floating rate of interest equal to USD-SOFR-COMPOUND plus a spread. The floating rate reset monthly and net settlements of interest due to/from the counterparty occurred monthly. To the extent that the fixed rate of interest exceeded USD-SOFR-COMPOUND plus the spread, the Company received net interest settlements, which were recorded as a reduction of deposit interest expense. If USD-SOFR-COMPOUND plus the spread exceeded the fixed rate of interest, the Company was required to pay net settlements to the counterparty and record those net payments as interest expense on deposits.

In January 2024, the Company elected to terminate these swaps prior to their contractual termination date in 2025. The Company received a net settlement payment from the swap counterparty totaling $26,500 upon termination. At the time of the early termination, the Company recorded a market value adjustment to the brokered deposits of $163,000, which is being amortized as a reduction of interest expense beginning in January 2024 through February 2025.

Cash Flow Hedges

Interest Rate Swaps. As a strategy to maintain acceptable levels of exposure to the risk of changes in future cash flows due to interest rate fluctuations, in October 2018, the Company entered into an interest rate swap transaction as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of the swap was $400 million with a termination date of October 6, 2025. Under the terms of the swap, the Company received a fixed rate of interest of 3.018% and paid a floating rate of interest equal to one-month USD-LIBOR. The floating rate was reset monthly and net settlements of interest due to/from the counterparty also occurred monthly. To the extent that the fixed rate of interest exceeded one-month USD-LIBOR, the Company received net interest settlements which were recorded as loan interest income. If USD-LIBOR exceeded the fixed rate of interest, the Company was required to pay net settlements to the counterparty and record those net payments as a reduction of interest income on loans.

In March 2020, the Company and its swap counterparty mutually agreed to terminate the $400 million interest rate swap prior to its contractual maturity. The Company was paid $45.9 million from its swap counterparty as a result of this termination. This $45.9 million, less the accrued interest portion and net of deferred income taxes, was reflected in the Company’s stockholders’ equity as part of Accumulated Other Comprehensive Income (AOCI) and a portion of it is being accreted to interest income on loans monthly through the original contractual termination date of October 6, 2025. This has the effect of reducing Accumulated Other Comprehensive Income and increasing Net Interest Income and Retained Earnings over the period. At June 30, 2024, the Company expected to have a sufficient amount of eligible variable rate loans to continue to accrete this interest income on the terminated swap in future periods. If this expectation changes and the amount of eligible variable rate loans decreases significantly, the Company may be required to recognize this interest income more rapidly. The Company recorded $2.0 million of interest income related to this terminated swap in each of the three-month periods ended June 30, 2024 and 2023. The Company recorded $4.1 million of interest income related to the swap in the six months ended June 30, 2024 and $4.0 million of interest income related to the swap in the six months ended June 30, 2023.

34

​

In March 2022, the Company entered into an interest rate swap transaction as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of the swap was $300 million, with a termination date of March 1, 2024. Under the terms of the swap, the Company received a fixed rate of interest of 1.6725% and paid a floating rate of interest equal to one-month USD-LIBOR (or the equivalent replacement USD-SOFR rate once USD-LIBOR rate ceased to be available). The floating rate reset monthly and net settlements of interest due to/from the counterparty also occurred monthly. To the extent the floating rate of interest exceeded the fixed rate of interest, the Company was required to pay net settlements to the counterparty and record those net payments as a reduction of interest income on loans. If the fixed rate of interest exceeded the floating rate of interest, the Company received net interest settlements, which were recorded as loan interest income. As this interest rate swap reached its contractual termination date of March 1, 2024, there has been no further interest income impact related to this swap after the three months ended March 31, 2024. The Company recorded a reduction of loan interest income related to this swap transaction of $1.9 million in the six months ended June 30, 2024. The Company recorded a reduction of loan interest income related to this swap transaction of $2.6 million and $4.7 million, respectively, in the three and six months ended June 30, 2023.

In July 2022, the Company entered into two additional interest rate swap transactions as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of each swap is $200 million with an effective date of May 1, 2023 and a termination date of May 1, 2028. Under the terms of one swap, the Company receives a fixed rate of interest of 2.628% and pays a floating rate of interest equal to one-month USD-SOFR OIS. Under the terms of the other swap, the Company receives a fixed rate of interest of 5.725% and pays a floating rate of interest equal to one-month USD-Prime. In each case, the floating rate resets monthly and net settlements of interest due to/from the counterparty also occur monthly. To the extent the fixed rate of interest exceeds the floating rate of interest, the Company receives net interest settlements, which is recorded as loan interest income. If the floating rate of interest exceeds the fixed rate of interest, the Company pays net settlements to the counterparty and records those net payments as a reduction of interest income on loans. At June 30, 2024, the USD-Prime rate was 8.50% and the one-month USD-SOFR OIS rate was 5.33643%. The Company recorded a reduction of loan interest income related to these swap transactions of $2.8 million and $1.7 million, respectively, in the three months ended June 30, 2024 and 2023. The Company recorded a reduction of loan interest income related to these swap transactions totaling $5.5 million and $1.7 million, respectively, in the six months ended June 30, 2024 and 2023.

The effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affected earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings. During each of the three and six months ended June 30, 2024 and 2023, the Company recognized no non-interest income related to changes in the fair value of these derivatives.

Agreements with Derivative Counterparties

The Company has agreements with its derivative counterparties. If the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender, then the Company could also be declared in default on its derivative obligations. If the Bank fails to maintain its status as a well-capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. Similarly, the Company could be required to settle its obligations under certain of its agreements if certain regulatory events occur, such as the issuance of a formal directive, or if the Company’s credit rating is downgraded below a specified level.

​

At June 30, 2024, the termination value of derivatives with our derivative dealer counterparties (related to loan level swaps with commercial lending customers and interest rate swaps to hedge risk related to the Company’s variable rate loans) in an overall net asset position, which included accrued interest but excluded any adjustment for nonperformance risk, related to these agreements was $118,000. The Company has minimum collateral posting thresholds with its derivative dealer counterparties. At June 30, 2024, the Company had given cash collateral to one derivative counterparty of $13.3 million to cover its net fair value position. This counterparty position included collateral from the counterparty of $8.9 million for commercial lending swaps and collateral from the Company of $22.2 million for interest rate swaps related to variable rate loans.

At December 31, 2023, the termination value of derivatives with our derivative dealer counterparties (related to loan level swaps with commercial lending customers and interest rate swaps to hedge risk related to the Company’s variable rate loans) in an overall net asset position, which included accrued interest but excluded any adjustment for nonperformance risk, related to these agreements was $137,000. The Company has minimum collateral posting thresholds with its derivative dealer counterparties. At December 31, 2023, the Company had given cash collateral to one derivative counterparty of $11.6 million to cover its net fair value position. This counterparty position included collateral from the counterparty of $8.2 million for commercial lending swaps, collateral from the Company of $19.2 million for interest rate swaps related to variable rate loans and collateral from the Company of $44,000 for swaps related to brokered deposits.

If the Company had breached any of these provisions at June 30, 2024 or December 31, 2023, it could have been required to settle its obligations under the agreements at the termination value. Under the collateral agreements between the parties, either party may choose to provide cash or securities to satisfy its collateral requirements.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Forward-looking Statements

When used in this Quarterly Report on Form 10-Q and in other documents filed or furnished by Great Southern Bancorp, Inc. (the “Company”) with the Securities and Exchange Commission (the “SEC”), in the Company’s press releases or other public or stockholder communications, and in oral statements made with the approval of an authorized executive officer, the words or phrases “may,” “might,” “could,” “should,” “will likely result,” “are expected to,” “will continue,” “is anticipated,” “believe,” “estimate,” “project,” “intends” or similar expressions are intended to identify “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements also include, but are not limited to, statements regarding plans, objectives, expectations or consequences of announced transactions, known trends and statements about future performance, operations, products and services of the Company. The Company’s ability to predict results or the actual effects of future plans or strategies is inherently uncertain, and the Company’s actual results could differ materially from those contained in the forward-looking statements.

Factors that could cause or contribute to such differences include, but are not limited to: (i) expected revenues, cost savings, earnings accretion, synergies and other benefits from the Company’s merger and acquisition activities might not be realized within the anticipated time frames or at all, and costs or difficulties relating to integration matters, including but not limited to customer and employee retention, might be greater than expected; (ii) changes in economic conditions, either nationally or in the Company’s market areas; (iii) the remaining effects of the COVID-19 pandemic on general economic and financial market conditions and on public health; (iv) fluctuations in interest rates, the effects of inflation or a potential recession, whether caused by Federal Reserve actions or otherwise; (v) the impact of bank failures or adverse developments at other banks and related negative press about the banking industry in general on investor and depositor sentiment; (vi) slower economic growth caused by changes in energy prices, supply chain disruptions or other factors; (vii) the risks of lending and investing activities, including changes in the level and direction of loan delinquencies and write-offs and changes in estimates of the adequacy of the allowance for credit losses; (viii) the possibility of realized or unrealized losses on securities held in the Company’s investment portfolio; (ix) the Company’s ability to access cost-effective funding and maintain sufficient liquidity; (x) fluctuations in real estate values and both residential and commercial real estate market conditions; (xi) the ability to adapt successfully to technological changes to meet customers’ needs and developments in the marketplace; (xii) the possibility that security measures implemented might not be sufficient to mitigate the risk of a cyber-attack or cyber theft, and that such security measures might not protect against systems failures or interruptions; (xiii) legislative or regulatory changes that adversely affect the Company’s business; (xiv) changes in accounting policies and practices or accounting standards; (xv) results of examinations of the Company and Great Southern Bank by their regulators, including the possibility that the regulators may, among other things, require the Company to limit its business activities, change its business mix, increase its allowance for credit losses, write-down assets or increase its capital levels, or affect its ability to borrow funds or maintain or increase deposits, which could adversely affect its liquidity and earnings; (xvi) costs and effects of litigation, including settlements and judgments; (xvii) competition; (xviii) natural disasters, war, terrorist activities or civil unrest and their effects on economic and business environments in which the Company operates. The Company wishes to advise readers that the factors listed above and other risks described in the Company’s most recent Annual Report on Form 10-K, including, without limitation, those described under “Item 1A. Risk Factors,” subsequent Quarterly Reports on Form 10-Q and other documents filed or furnished from time to time by the Company with the SEC (which are available on our website at www.greatsouthernbank.com and the SEC’s website at www.sec.gov), could affect the Company’s financial performance and cause the Company’s actual results for future periods to differ materially from any opinions or statements expressed with respect to future periods in any current statements.

The Company does not undertake-and specifically declines any obligation- to publicly release the result of any revisions which may be made to any forward-looking statements to reflect events or circumstances after the date of such statements or to reflect the occurrence of anticipated or unanticipated events.

Critical Accounting Policies, Judgments and Estimates

The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States and general practices within the financial services industry. The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results could differ from those estimates.

​

Allowance for Credit Losses and Valuation of Foreclosed Assets

On January 1, 2021, the Company adopted the new accounting standard related to the allowance for credit losses. This standard eliminates the probable initial recognition threshold in GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. See Note 6 “Loans and Allowance for Credit Losses” in the Notes to Consolidated Financial Statements included in this report for additional information.

The Company believes that the determination of the allowance for credit losses involves a higher degree of judgment and complexity than its other significant accounting policies. The allowance for credit losses is calculated with the objective of maintaining an allowance level believed by management to be sufficient to absorb estimated credit losses. The allowance for credit losses is measured using an average historical loss model that incorporates relevant information about past events (including historical credit loss experience on loans with similar risk characteristics), current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the loans. The allowance for credit losses is measured on a collective (pool) basis. Loans are aggregated into pools based on similar risk characteristics, including borrower type, collateral and repayment types and expected credit loss patterns. Loans that do not share similar risk characteristics, primarily classified loans with a balance greater than or equal to $100,000, are evaluated on an individual basis.

For loans evaluated for credit losses on a collective basis, average historical loss rates are calculated for each pool using the Company’s historical net charge-offs (combined charge-offs and recoveries by observable historical reporting period) and outstanding loan balances during a lookback period. Lookback periods can be different based on the individual pool and represent management’s credit expectations for the pool of loans over the remaining contractual life. In certain loan pools, if the Company’s own historical loss rate is not reflective of the loss expectations, the historical loss rate is augmented by industry and peer data. The calculated average net charge-off rate is then adjusted for current conditions and reasonable and supportable forecasts. These adjustments increase or decrease the average historical loss rate to reflect expectations of future losses given economic forecasts of key macroeconomic variables including, but not limited to, unemployment rate, GDP, commercial real estate price index, consumer sentiment and construction spending. The adjustments are based on results from various regression models projecting the impact of the macroeconomic variables to loss rates. The forecast is used for a reasonable and supportable period before reverting to historical averages using a straight-line method. The forecast-adjusted loss rate is applied to the principal balance over the remaining contractual lives, adjusted for expected prepayments. The contractual term excludes expected extensions, renewals and modifications. Additionally, the allowance for credit losses considers other qualitative factors not included in historical loss rates or macroeconomic forecasts such as changes in portfolio composition, underwriting practices, or significant unique events or conditions.

See Note 6 “Loans and Allowance for Credit Losses” in the Notes to Consolidated Financial Statements included in this report for additional information regarding the allowance for credit losses. Inherent in this process is the evaluation and risk assessment of individual credit relationships. From time to time, certain credit relationships may deteriorate due to changes in payment performance, cash flow of the borrower, value of collateral, or other factors. Due to these changing circumstances, management may revise its loss estimates and assumptions for these specific credits. In some cases, losses may be realized; in other instances, the factors that led to the deterioration may improve or the credit may be refinanced elsewhere and allocated allowances may be released from the particular credit.

In addition, the Company considers that the determination of the valuation of foreclosed assets held for sale involves a high degree of judgment and complexity. The carrying value of foreclosed assets reflects management's best estimate of the amount to be realized from the sale of the assets. While the estimate is generally based on a valuation by an independent appraiser or recent sales of similar properties, the amount that the Company realizes from the sale of the assets could differ materially from the carrying value reflected in the financial statements, resulting in gains or losses that could materially impact earnings in future periods.

Goodwill and Intangible Assets

Goodwill and intangible assets that have indefinite useful lives are subject to an impairment test at least annually and more frequently if circumstances indicate their value may not be recoverable. Goodwill is tested for impairment using a process that estimates the fair value of each of the Company’s reporting units compared with its carrying value. The Company defines reporting units as a level below each of its operating segments for which there is discrete financial information that is regularly reviewed. As of June 30, 2024, the Company had one reporting unit to which goodwill has been allocated – the Bank. If the fair value of a reporting unit exceeds its carrying value, then no impairment is recorded. If the carrying value exceeds the fair value of a reporting unit, further testing is completed comparing the implied fair value of the reporting unit’s goodwill to its carrying value to measure the amount of impairment. Intangible assets that are not amortized will be tested for impairment at least annually by comparing the fair values of those assets to their carrying values. At June 30, 2024, goodwill consisted of $5.4 million at the Bank reporting unit, which included goodwill of $4.2 million that was recorded during 2016 related to the acquisition of 12 branches and the assumption of related deposits

39

​

in the St. Louis market. Other identifiable deposit intangible assets that are subject to amortization are amortized on a straight-line basis over a period of seven years.

In April 2022, the Company, through its subsidiary Great Southern Bank, entered into a naming rights agreement with Missouri State University related to the main arena on the university’s campus in Springfield, Missouri. The terms of the agreement provide the naming rights to Great Southern Bank for a total cost of $5.5 million, to be paid over a period of seven years. The Company expects to amortize the intangible asset through non-interest expense over a period not to exceed 15 years.

At June 30, 2024, the amortizable intangible assets included the arena naming rights of $4.9 million, which are reflected in the table below. These amortizable intangible assets are reviewed for impairment if circumstances indicate their value may not be recoverable based on a comparison of fair value.

For purposes of testing goodwill for impairment, the Company uses a market approach to value its reporting unit. The market approach applies a market multiple, based on observed purchase transactions for each reporting unit, to the metrics appropriate for the valuation of the operating unit. Significant judgment is applied when goodwill is assessed for impairment. This judgment may include developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables and incorporating general economic and market conditions.

Management does not believe any of the Company’s goodwill or other intangible assets were impaired as of June 30, 2024. While management believes no impairment existed at June 30, 2024, different conditions or assumptions used to measure fair value of the reporting unit, or changes in cash flows or profitability, if significantly negative or unfavorable, could have a material adverse effect on the outcome of the Company’s impairment evaluation in the future.

A summary of goodwill and intangible assets as of the date indicated is as follows:

​ | ​ | June 30, | ​ | December 31,

Current Economic Conditions

Changes in economic conditions could cause the values of assets and liabilities recorded in the Company’s financial statements to change rapidly, resulting in material future adjustments to asset values, the allowance for credit losses, or capital that could negatively affect the Company’s ability to meet regulatory capital requirements and maintain sufficient liquidity. Following the housing and mortgage crisis and correction beginning in mid-2007, the United States entered an economic downturn. Unemployment rose from 4.7% in November 2007 to peak at 10.0% in October 2009. Economic conditions improved in the subsequent years, as indicated by higher consumer confidence levels, increased economic activity and low unemployment levels. The U.S. economy continued to operate at historically strong levels until the COVID-19 pandemic in March 2020, which severely affected tourism, labor markets, business travel, immigration, and the global supply chain, among other areas. The economy plunged into recession in the first quarter of 2020, as efforts to contain the spread of the coronavirus forced all but essential business activity, or any work that could not be done from home, to stop, shuttering factories, restaurants, entertainment, sporting events, retail shops, personal services, and more.

More than 22 million jobs were lost in March and April 2020 as businesses closed their doors or reduced their operations, sending employees home on furlough or layoffs. With uncertain incomes and limited buying opportunities, consumer spending plummeted. As a result, gross domestic product (GDP), the broadest measure of the nation’s economic output, plunged. The Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”), a fiscal relief bill passed by Congress and signed by the President in March 2020, injected approximately $3 trillion into the economy through direct payments to individuals and loans to small businesses intended to help keep employees on their payroll, fueling a historic bounce-back in economic activity.

Total fiscal support to the economy throughout the pandemic, including the CARES Act, the American Rescue Plan of March 2021, and several smaller fiscal packages, totaled well over $5 trillion. The amount of this support was equal to almost 25% of pre-pandemic 2019 GDP and approximately three times the level of support provided during the global financial crisis of 2007-2008.

Additionally, the Federal Reserve acted decisively by slashing its benchmark interest rate to near zero and ensuring credit availability to businesses, households, and municipal governments. The Federal Reserve’s efforts largely insulated the financial system from the

40

​

problems in the economy, a significant difference from the financial crisis of 2007-2008. Purchases of Treasury and agency mortgage-backed securities totaling $120 billion each month by the Federal Reserve commenced shortly after the pandemic began. In November 2021, the Federal Reserve began to taper its quantitative easing (QE), winding down its bond purchases with its final open market purchase conducted on March 9, 2022. The federal government deficit was $2.8 trillion in fiscal 2021, close to $1.4 trillion in fiscal 2022, and $1.7 trillion in fiscal 2023.

The Federal Reserve aggressively raised the federal funds interest rates from early 2022 through mid-2023, pushing the federal funds rate to more than 5.50%, its highest level in 22 years. The Federal Reserve’s actions were motivated by surging inflation in 2021 caused by pandemic-fueled spending, which outpaced the ability of producers to supply goods and services after having been impacted by COVID-related shutdowns and clogged transportation systems. The Federal Reserve has made some headway in its attempt to force inflation down. The personal consumption expenditures (PCE) price index, the Federal Reserve's preferred measure of inflation, eased from its peak of 7.1% in June 2022 to 2.9% in December 2023, but core PCE, which excludes food and energy prices, has been slower to retreat and sat at 2.6% at June 2024, still above the Federal Reserve's target of 2%.

Moody’s is projecting real GDP in 2024 to be slightly lower than previously forecast, as the persistence of high interest rates continues to impact GDP growth rates. Real GDP is projected to rise 2.4% in 2024 on an annual average basis, a downward revision of 0.1%, and is projected to grow to 1.8% in 2025 and 1.9% in 2026. The actual real GDP quarterly increase in the first quarter of 2024 was 1.4% and the second quarter of 2024 advance estimate for real GDP was a quarterly increase of 2.8%.

Employment

The national unemployment rate was 4.1% as of June 2024 and has ranged from 3.4% to 4.1% since June 2022. The number of unemployed individuals remained steady at 6.8 million as of June 2024, with 206,000 jobs added in June 2024. In June 2024, employment gains in healthcare, government, and construction contributed to 153,000 of the total job gains.

As of June 2024, the labor force participation rate (the share of working - age Americans employed or actively looking for a job) remained stable at 62.6%. The unemployment rate for the Midwest, where the Company conducts most of its business, has increased from 3.4% in June 2023 to 3.8% in June 2024. Unemployment rates for June 2024 in the states where the Company has a branch or a loan production office were Arizona at 3.3%, Arkansas at 3.3%, Colorado at 3.8%, Georgia at 3.3%, Illinois at 5.0%, Iowa at 2.8%, Kansas at 3.1%, Minnesota at 2.9%, Missouri at 3.7%, Nebraska at 2.6%, North Carolina at 3.6%, and Texas at 4.0%. The rates are slightly higher for many of these states compared to March 2024. Of the metropolitan areas in which the Company does business, most are below the national unemployment rate for June 2024 of 4.1%.

Single Family Housing

Existing - home sales decreased to a seasonally adjusted annual rate of 3.89 million in June 2024, down 5.4% from the previous year. In the Midwest, existing - home sales declined to an annual rate of 920,000 in June 2024, down 6.1% from one year ago.

The median existing - home sales price rose 4.1% from June 2023 to an all - time high of $426,900 in June 2024. All four U.S. regions registered price gains. The median price in the Midwest was $327,100, up 5.5% from June 2023.

Total housing inventory registered at the end of June 2024 was 1.32 million units, up 3.1% from May 2024 and up 23.4% from one year ago of 1.07 million units. Unsold inventory sat at a 4.1 - month supply in June 2024, up from 3.7 months in May 2024 and up from 3.1 months in June 2023.

New home construction dropped precipitously after the financial crisis of 2007-2008 and has yet to fully recover. Issues contributing to the country’s current housing shortage include increasing labor and materials costs, availability of building materials, increased interest rates and tighter lending underwriting standards.

Sales of new single - family houses in June 2024 were at a seasonally adjusted annual rate of 617,000, according to the U.S. Census Bureau and the Department of Housing and Urban Development. This was 0.6% below the revised May 2024 rate of 621,000 and was 7.4% below the June 2023 rate of 666,000.

The median sales price of new houses sold in June 2024 was $417,300, up from $415,400 in June 2023. The average sales price in June 2024 of $487,200 was down from $494,700 in June 2023. The seasonally - adjusted estimate of new houses for sale at the end of June 2024 was 476,000. This represents a supply of 9.3 months at the current sales rate.

According to Freddie Mac, the average commitment rate for a 30 - year, fixed - rate mortgage was 6.77% as of July 22, 2024, which is down from 6.89% for the previous week and down from 6.78% one year ago.

Other Residential (Multi-Family) Housing and Commercial Real Estate

The U.S. multi - family market experienced a healthy rebound in demand for the first half of 2024, driven by rising consumer confidence and diminishing recession fears. Despite the notable growth in demand in 2024, the influx of new supply continues to saturate the market. During the first quarter of 2024, 153,000 units were completed, with an estimated 163,000 units expected to be delivered in the second quarter. Most new supply additions are concentrated at the 4 and 5 Star price point, contributing to the weakest rent growth observed in this market. Consequently, the persistent imbalance between supply and demand is projected to increase the vacancy rate, which is expected to reach a record 7.9% by the end of June 2024.

The Midwest and Northeast have fared the best over the past two years seeing the most favorable rent growth. The Sun Belt market rent growth has been more sluggish, with numerous markets reporting negative year over year rent growth by the end of May 2024. Current projections indicate 533,000 completions for the year, reflecting a 9% decline from the record supply seen in 2023. At the same time, absorption is accelerating, offering the national market an opportunity to stabilize and possibly begin recovering by the end of 2024.

The June 2024 national multi-family market vacancy rates remained consistent with the previous quarter at 7.8%. Our market areas reflected the following apartment vacancy levels as of June 2024: Springfield, Missouri at 5.3%, St. Louis at 9.5%, Kansas City at 7.7%, Minneapolis at 7.3%, Dallas-Fort Worth at 10.6%, Chicago at 5.6%, Atlanta at 12.3%, Phoenix at 11.0%, Denver at 9.6% and Charlotte, North Carolina at 12.3%. The rates are slightly higher for some of these cities compared to March 2024.

Absorption was positive in the second quarter of 2024 for the office industry, but supply additions held vacancy at 13.8%. Owner occupied, medical office users, and fewer high profile move-outs drove the uptick in occupancy, but persistently small leases and looming rollover exposure suggest the reprieve is likely temporary.

The 89.1 million SF under construction is the lowest amount since 2013, and the 20 million SF in construction starts over the past year is the lowest amount on record for a 12-month period. Net deliveries are expected to taper off to a negligible amount by the end of 2025, which should tighten the market for desirable existing space. Asking rental rates are still expected to dip as basis resets. An additional value correction over the next 12-18 months is expected as a steady stream of low rate loans maturing into a high-rate environment provides motivation for repricing.

New leasing volume has hovered around 10% below the average amount from 2015-2019. Much of the decline in volume has been driven by average lease sizes 15-20% smaller than the 2015-2019 average. Market participants confirm that, while the leasing market is active, typical requirements are smaller, with pre-built spec suites attracting some of the strongest demand. In the traditional leasing market, however, there has been an ongoing adjustment in per-worker space needs, with new construction winning out. Buildings completed during the current decade have maintained positive net absorption but older properties have suffered from an extreme lack of demand.

During the next 18-24 months, about 25% of square footage leased before April 2020 is set to expire. Thus, the outlook is for a continued rise in vacancy, which is expected to increase approximately 1.5% by early 2026.

As of June 2024, national office vacancy rates remained stable at 13.8% compared to March 2024, while our market areas reflected the following vacancy levels: Springfield, Missouri at 4.5%, St. Louis at 10.5%, Kansas City at 12.3%, Minneapolis at 11.5%, Dallas-Fort Worth at 18.2%, Chicago at 16.3%, Atlanta at 16.4%, Denver at 17.0%, Phoenix at 16.8% and Charlotte, North Carolina at 14.3%. The rates are higher for many of these cities compared to March 2024.

The U.S. retail market is in one of its firmest fundamental positions on record thanks to steadily rising demand, a significant reduction in tenant bankruptcies and store closures, and limited new supply. Demand for retail space has increased by 40.1 million SF during the past 12 months and over 212 million SF since the start of 2021. While the increase in demand for space has been driven by growth from numerous sources, the most significant gains are from tenants in the food and beverage, discount, off-price, and experiential sectors, which combined accounted for over half of all new leasing activity over the past year.

While demand for space continues to rise, new retail development activity remains minimal. Approximately 36.5 million SF of new retail space was delivered across the U.S. over the past 12 months, which is half of the prior 10-year average. Most retail construction activity comprises single-tenant build-to-suits or smaller ground-floor spaces in mixed-use developments. Given the structural downshift in activity coupled with the fact that over three years of new deliveries have typically had a tenant in place at delivery, the

42

​

U.S. retail market has faced virtually no threat from new supply. This looks to continue for the foreseeable future, as retail construction starts fell to new historic lows as higher interest rates challenge the feasibility of many new potential retail developments at current rent levels. Rents continue to rise due to minimal availability and the significant boost in retail sales coming out of the pandemic. Asking rents for retail spaces have increased by 2.4% over the past year to a new record high of $25.00 per SF.

During the second quarter of 2024, national retail vacancy rates remained steady at 4.1% while our market areas reflected the following vacancy levels: Springfield, Missouri at 2.2%, St. Louis at 4.2%, Kansas City at 3.9%, Minneapolis at 2.5%, Dallas-Fort Worth at 4.5%, Chicago at 4.8%, Atlanta at 3.6%, Phoenix at 4.8%, Denver at 3.7%, and Charlotte, North Carolina at 2.6%. The rates are slightly lower for many of these cities compared to March 2024.

U.S. industrial market performance continued to downshift in the second quarter of 2024. While the national vacancy rate is not expected to rise well above its 20-year average of 7.1%, the next 6-12 months could still prove to be the market's most challenging period over the next five years. Net absorption has remained positive but continued to lose steam, with the first quarter of 2024 registering the lowest first quarter absorption tally since 2012. This weakness partly reflects recent 12-year lows in home sales, which has lowered sales of furniture, building materials, and appliances, leading to large distribution center closures by tenants including Bed Bath & Beyond, Ashley Furniture, and Home Depot. Third-party distributors that leased ahead of their long-term space needs during the pandemic have also been closing facilities they opened during 2020-2022.

Oncoming new supply will likely push the national vacancy rate up further through late 2024. Higher interest rates have caused construction starts on new industrial projects to plummet since last fall. The volume of projects completing construction each quarter has already begun to decline and will likely hit 10-year lows in late 2025. This could set the stage for vacancies to begin tightening again and for rent growth to accelerate thereafter.

Overall growth in real consumer goods spending has been re-accelerating since last spring as inflation gradually subsides. Large distribution center expansions by companies that sell necessities consumers are still purchasing in high volume, including Burlington Coat Factory, TJX Companies, Chuck and Dwight, and Nestle USA, which have all signed new leases larger than 700,000 SF this year.

While a potential stagnation in consumer spending poses downside risks in CoStar's absorption forecast for the next 12 months, high-tech manufacturing will likely be a key driver of leasing from 2024–26. The 2022 passage of the CHIPS and Science Act and the Inflation Reduction Act approved over $400 billion worth of incentives for growth in U.S. based high-tech manufacturing. CoStar is tracking more than 30 planned semiconductor, electric vehicle, and battery plants with estimated payrolls of more than 1,000 employees. The majority of these plants are targeting 2024–26 to begin production, with Arizona, Texas, Georgia, and the Carolinas securing the most new operations.

The trend of slowing absorption and rising space availability rates has been broad-based across major U.S. markets. Higher interest rates have caused construction starts on new industrial projects to halt. Given the average construction time of 14 months for large industrial projects, this recent pullback in starts signals that by late 2024, the number of new projects completing construction should continue to decline.

For the second quarter of 2024, national industrial vacancy rates increased to 6.6%, from 6.2% for the first quarter of 2024. Our market areas reflected the following industrial vacancy levels: Springfield, Missouri at 1.7%, St. Louis at 4.5%, Kansas City at 5.5%, Minneapolis at 4.4%, Dallas-Fort Worth at 9.6%, Chicago at 5.3%, Atlanta at 7.5%, Phoenix at 10.5%, Denver at 8.4% and Charlotte, North Carolina at 7.7%.

Our management will continue to monitor regional, national, and global economic indicators such as unemployment, GDP, housing starts and prices, consumer sentiment, commercial real estate price index and commercial real estate occupancy, absorption and rental rates, as these could significantly affect customers in each of our market areas.

General

The profitability of the Company and, more specifically, the profitability of its primary subsidiary, the Bank, depends primarily on its net interest income, as well as provisions for credit losses and the level of non-interest income and non-interest expense. Net interest income is the difference between the interest income the Bank earns on its loans and investment portfolios, and the interest it pays on interest-bearing liabilities, which consists mainly of interest paid on deposits and borrowings. Net interest income is affected by the relative amounts of interest-earning assets and interest-bearing liabilities and the interest rates earned or paid on these balances. When interest-earning assets approximate or exceed interest-bearing liabilities, any positive interest rate spread will generate net interest income.

Great Southern’s total assets increased $146.4 million, or 2.5%, from $5.81 billion at December 31, 2023, to $5.96 billion at June 30, 2024. Details of the current period changes in total assets are provided below, under “Comparison of Financial Condition at June 30, 2024 and December 31, 2023.”

Loans. Net outstanding loans increased $44.0 million, or 1.0%, from $4.59 billion at December 31, 2023, to $4.63 billion at June 30, 2024. The increase was primarily in other residential (multi-family) loans and was partially offset by decreases in construction loans and commercial business loans. As loan demand is affected by a variety of factors, including general economic conditions, and because of the competition we face and our focus on pricing discipline and credit quality, we cannot be assured that our loan growth will match or exceed the average level of growth achieved in prior years. The Company’s strategy continues to be focused on maintaining credit risk and interest rate risk at appropriate levels.

Recent growth has occurred in some loan types, primarily other residential (multi-family) and in most of Great Southern’s primary lending locations, including Springfield, St. Louis, Kansas City, Des Moines and Minneapolis, as well as our loan production offices in Atlanta, Charlotte, Chicago, Dallas, Denver, Omaha, and Phoenix. Underwriting standards and monitoring procedures utilized by the Company are designed to help assure the Company’s portfolio quality. All new loan originations that exceed lender approval authorities are subject to review and approval by Great Southern’s loan committee. Generally, the Company considers commercial construction, consumer, other residential (multi-family) and commercial real estate loans to involve a higher degree of risk compared to some other types of loans, such as first mortgage loans on one- to four-family, owner-occupied residential properties. For other residential (multi-family), commercial real estate, commercial business and construction loans, the credits are subject to an analysis of the borrower’s and guarantor’s financial condition, credit history, verification of liquid assets, collateral, market analysis and repayment ability. It has been, and continues to be, Great Southern’s practice to verify information from potential borrowers regarding assets, income or payment ability and credit ratings as applicable and as required by the authority approving the loan. To minimize construction risk, projects are monitored as construction draws are requested by comparison to budget and with progress verified through property inspections. The geographic and product diversity of collateral, equity requirements and limitations on speculative construction projects help to mitigate overall risk in these loans. Underwriting standards for all loans also include loan-to-value ratio limitations, which vary depending on collateral type, debt service coverage ratios or debt payment to income ratio guidelines, where applicable, credit histories, use of guaranties and other recommended terms relating to equity requirements, amortization, and maturity. Consumer loans, other than home equity loans, are primarily secured by new or used motor vehicles and these loans are subject to underwriting standards designed to assure portfolio quality. In 2019, the Company discontinued indirect auto loan originations.

While our policy allows us to lend up to 95% of the appraised value on one-to four-family residential properties, originations of loans with loan-to-value ratios at that level are minimal. Private mortgage insurance is typically required for loan amounts above the 80% level. Few exceptions occur and would be based on analyses which determined minimal transactional risk to be involved. We consider these lending practices to be consistent with or more conservative than what we believe to be the norm for banks our size. At both June 30, 2024 and December 31, 2023, 0.2% of our owner occupied one-to four-family residential loans had loan-to-value ratios above 100% at origination and an estimated 0.4% of our non-owner occupied one- to four-family residential loans had loan-to-value ratios above 100% at origination.

The level of non-performing loans and foreclosed assets affects our net interest income and net income. We generally do not accrue interest income on these loans and do not recognize interest income until the loans are repaid or interest payments have been made for a period of time sufficient to provide evidence of improved repayment ability on the loans. Generally, the higher the level of non-performing assets, the greater the negative impact on interest income and net income.

Available-for-sale Securities. In the six months ended June 30, 2024, available-for-sale securities increased $70.9 million, or 14.8%, from $478.2 million at December 31, 2023, to $549.1 million at June 30, 2024. In the three months ended June 30, 2024, the Company elected to purchase some fixed rate securities similar to ones already in its portfolio, to provide interest rate protection if market interest rates should fall in future periods. These securities are expected to yield over 5.00%.

Held-to-maturity Securities. In the six months ended June 30, 2024, held-to-maturity securities decreased $3.8 million, or 1.9%, from $195.0 million at December 31, 2023, to $191.2 million at June 30, 2024. See Note 5 “Investment Securities” in the Notes to Consolidated Financial Statements included in this report for additional information.

Deposits. The Company attracts deposit accounts through its retail branch network, correspondent banking and corporate services areas, internet channels and brokered deposits. The Company then utilizes these deposit funds, along with FHLBank advances and other borrowings, to meet loan demand or otherwise fund its activities. In the six months ended June 30, 2024, total deposit balances decreased $106.4 million, or 2.3%. Compared to December 31, 2023, transaction account balances decreased $50.7 million, or 1.6%, to $3.06 billion at June 30, 2024, and retail certificates of deposit decreased $64.2 million, or 6.8%, to $884.0 million at June 30,

44

​

2024. The decrease in transaction accounts was primarily a result of a decrease in non-interest-bearing accounts and various NOW accounts, as small businesses and individuals appear to be drawing down their balances to pay for goods and services, or are seeking a higher-yielding alternative. Retail time deposits decreased due to a decrease in retail certificates generated through the banking center network. Competition for time deposits remains significant in many of our markets. Brokered deposits, including IntraFi program purchased funds, were $670.0 million and $661.5 million at June 30, 2024 and December 31, 2023, respectively. The Company uses brokered deposits of select maturities from time to time to supplement its various funding channels and to manage interest rate risk.

Our deposit balances may fluctuate depending on customer preferences and our relative need for funding. We do not consider our retail certificates of deposit to be guaranteed long-term funding because customers can withdraw their funds at any time with minimal interest penalty. When loan demand trends upward, we can increase rates paid on deposits to attract more deposits and utilize brokered deposits to generate additional funding. The level of competition for deposits in our markets is high. It is our goal to gain deposit market share, particularly checking accounts, in our branch footprint. To accomplish this goal, increasing rates to attract deposits may be necessary, which could negatively impact the Company’s net interest margin.

Our ability to fund growth in future periods may also depend on our ability to continue to access brokered deposits and FHLBank advances. In times when our loan demand has outpaced our generation of new deposits, we have utilized brokered deposits and FHLBank advances to fund these loans. These funding sources have been attractive to us because we can create either fixed or variable rate funding, as desired, which more closely matches the interest rate nature of much of our loan portfolio. It also gives us greater flexibility in increasing or decreasing the duration of our funding. While we do not currently anticipate that our ability to access these sources will be reduced or eliminated in future periods, if this should happen, the limitation on our ability to fund additional loans could have a material adverse effect on our business, financial condition and results of operations. See “Results of Operations and Comparison for the Three and Six Months Ended June 30, 2024 and 2023 – Liquidity” below for further information on funding sources.

Securities sold under reverse repurchase agreements with customers. Securities sold under reverse repurchase agreements with customers increased $3.4 million from $70.8 million at December 31, 2023 to $74.2 million at June 30, 2024. These balances fluctuate over time based on customer demand for this product.

Short-term borrowings and other interest-bearing liabilities. Short term borrowings and other interest-bearing liabilities increased $223.7 million from $252.6 million at December 31, 2023 to $476.3 million at June 30, 2024. The Company may, from time to time, utilize overnight borrowings, short-term FHLBank advances, and BTFP borrowings from the Federal Reserve Bank of St. Louis (FRBSTL), depending on relative interest rates. The Company’s FHLBank term advances were $-0- at both June 30, 2024 and December 31, 2023. At June 30, 2024 and December 31, 2023, there was $295.0 million and $251.0 million, respectively, in overnight borrowings from the FHLBank, which were included in short term borrowings. In January 2024, the Bank borrowed $180.0 million under the BTFP program. The BTFP borrowing, which matures in January 2025 and has a fixed interest rate of 4.83%, may be repaid in full or in part without penalty prior to its stated maturity date. The line is secured primarily by the Bank’s held-to-maturity investment securities, with assets pledged totaling approximately $191.3 million at June 30, 2024. These funds were primarily used to repay a portion of the Bank’s overnight borrowings from the FHLBank.

Net Interest Income and Interest Rate Risk Management. Our net interest income may be affected positively or negatively by changes in market interest rates. A large portion of our loan portfolio is tied to one-month SOFR, three-month SOFR or the “prime rate” and adjusts immediately or shortly after the index rate adjusts (subject to the effect of contractual interest rate floors on some of the loans, which are discussed below). We monitor our sensitivity to interest rate changes on an ongoing basis (see “Quantitative and Qualitative Disclosures About Market Risk”).

The current level and shape of the interest rate yield curve poses challenges for interest rate risk management. Prior to its increase of 0.25% on December 16, 2015, the FRB had last changed interest rates on December 16, 2008. This was the first rate increase since September 29, 2006. The FRB also implemented rate change increases of 0.25% on eight additional occasions beginning December 14, 2016 and through December 31, 2018, with the Federal Funds rate reaching as high as 2.50%. After December 2018, the FRB paused its rate increases and, in July, September and October 2019, implemented rate decreases of 0.25% on each of those occasions. At December 31, 2019, the Federal Funds rate stood at 1.75%. In response to the COVID-19 pandemic, the FRB decreased interest rates on two occasions in March 2020, a 0.50% decrease on March 3rd and a 1.00% decrease on March 16th. At December 31, 2021, the Federal Funds rate was 0.25%. In 2022, the FRB implemented rate increases of 0.25%, 0.50%, 0.75%, 0.75%, 0.75%, 0.75% and 0.50% in March, May, June, July, September, November and December 2022, respectively. At December 31, 2022, the Federal Funds rate was 4.50%. In 2023, the FRB implemented rate increases of 0.25%, 0.25%, 0.25% and 0.25% in February, March, May and July 2023, respectively. At December 31, 2023, the Federal Funds rate was 5.50%. To date in 2024, the FRB has not implemented any rate changes and at June 30, 2024, the Federal Funds rate was 5.50%. Financial markets now expect the possibility of significant further increases in Federal Funds interest rates in 2024 to be unlikely, with interest rate decisions being made at each FRB meeting based on

​

economic data available at the time. However, the FRB has further indicated, and financial markets now have begun to price in, that it is likely that the Federal Funds interest rate will remain near this peak level for a few more months before any rate cuts occur, possibly as early as September 2024.

Great Southern’s loan portfolio includes loans ($1.41 billion at June 30, 2024) tied to various SOFR indexes that will be subject to adjustment at least once within 90 days after June 30, 2024. All of these loans have interest rate floors at various rates. Great Southern also has a portfolio of loans ($826 million at June 30, 2024) tied to a “prime rate” of interest that will adjust immediately or within 90 days of a change to the “prime rate” of interest. All of these loans had interest rate floors at various rates. In addition, Great Southern has a portfolio of loans ($7 million at June 30, 2024) tied to an AMERIBOR index that will adjust immediately or within 90 days of a change to the “prime rate” of interest. All of these loans had interest rate floors at various rates. At June 30, 2024, nearly all of these SOFR and “prime rate” loans had fully-indexed rates that were at or above their floor rate and so are expected to move fully with future market interest rate increases.

A rate cut by the FRB generally would have an anticipated immediate negative impact on the Company’s net interest income due to the large total balance of loans tied to the SOFR indexes or the “prime rate” index and will be subject to adjustment at least once within 90 days or loans which generally adjust immediately as the Federal Funds rate adjusts. Interest rate floors may at least partially mitigate the negative impact of interest rate decreases. Loans at their floor rates are, however, subject to the risk that borrowers will seek to refinance elsewhere at the lower market rate. There may also be a negative impact on the Company’s net interest income if the Company is unable to significantly lower its funding costs due to a highly competitive rate environment for deposits, although interest rates on assets may decline further. Conversely, market interest rate increases would normally result in increased interest rates on our SOFR-based, AMERIBOR-based and prime-based loans.

As of June 30, 2024, Great Southern’s interest rate risk models indicate that, generally, rising interest rates are expected to have a modestly positive impact on the Company’s net interest income, while declining interest rates are expected to have a modestly negative impact on net interest income. We model various interest rate scenarios for rising and falling rates, including both parallel and non-parallel shifts in rates. The results of our modeling indicate that net interest income is not likely to be significantly affected either positively or negatively in the first twelve months following relatively minor changes in market interest rates because our portfolios are relatively well-matched in a twelve-month horizon.

In a situation where market interest rates increase significantly in a short period of time, our net interest margin increase may be more pronounced in the very near term (first one to three months), due to fairly rapid increases in SOFR interest rates and “prime” interest rates. In a situation where market interest rates decrease significantly in a short period of time, as they did in March 2020, our net interest margin decrease may be more pronounced in the very near term (first one to three months), due to fairly rapid decreases in SOFR interest rates and “prime” interest rates. In the subsequent months, we would expect that net interest margin would stabilize and begin to improve, as renewal interest rates on maturing time deposits decrease.

During 2020, we experienced some compression of our net interest margin due to Federal Fund rate cuts during the nine-month period of July 2019 through March 2020. Margin compression primarily resulted from changes in the asset mix, mainly the addition of lower-yielding assets and the issuance of subordinated notes during 2020, and net interest margin remained lower than our historical average in 2021. LIBOR interest rates decreased significantly in 2020 and remained very low in 2021, putting pressure on loan yields, and strong pricing competition for loans and deposits remained in most of our markets.

Beginning in March 2022, market interest rates, including LIBOR interest rates, SOFR interest rates and “prime” interest rates, began to increase rapidly. This resulted in increasing loan yields and expansion of our net interest income and net interest margin throughout 2022 and into the first three months of 2023. In 2023, market interest rate increases moderated and loan yield increases moderated in line with market rates. However, there has been increased competition for deposits and other sources of funding, resulting in higher costs for those funds. This has been especially true since early March 2023. For further discussion of the processes used to manage our exposure to interest rate risk, see “Item 3. Quantitative and Qualitative Disclosures About Market Risk – How We Measure the Risks to Us Associated with Interest Rate Changes.”

Non-Interest Income and Non-Interest (Operating) Expenses. The Company’s profitability is also affected by the level of its non-interest income and operating expenses. Non-interest income consists primarily of service charges and ATM fees, POS interchange fees, late charges and prepayment fees on loans, gains on sales of loans and available-for-sale investments and other general operating income. Non-interest income may also be affected by the Company’s interest rate derivative activities, if the Company chooses to implement derivatives. See Note 16 “Derivatives and Hedging Activities” in the Notes to Consolidated Financial Statements included in this report.

46

​

Operating expenses consist primarily of salaries and employee benefits, occupancy-related expenses, expenses related to foreclosed assets, postage, FDIC deposit insurance, advertising and public relations, telephone, professional fees, office expenses and other general operating expenses. Details of the current period changes in non-interest income and non-interest expense are provided below, under “Results of Operations and Comparison for the Three and Six Months Ended June 30, 2024 and 2023.”

Effect of Federal Laws and Regulations

General. Federal legislation and regulation significantly affect the operations of the Company and the Bank, and have increased competition among commercial banks, savings institutions, mortgage banking enterprises and other financial institutions. In particular, the capital requirements and operations of regulated banking organizations such as the Company and the Bank have been and will be subject to changes in applicable statutes and regulations from time to time, which changes could, under certain circumstances, adversely affect the Company or the Bank.

Dodd-Frank Act. In 2010, sweeping financial regulatory reform legislation entitled the “Dodd-Frank Wall Street Reform and Consumer Protection Act” (the “Dodd-Frank Act”) was signed into law. The Dodd-Frank Act implemented far-reaching changes across the financial regulatory landscape. Certain aspects of the Dodd-Frank Act have been affected by the more recently enacted Economic Growth Act, as defined and discussed below under “-Economic Growth Act.”

Capital Rules. The federal banking agencies have adopted regulatory capital rules that substantially amend the risk-based capital rules applicable to the Bank and the Company. The rules implement the “Basel III” regulatory capital reforms and changes required by the Dodd-Frank Act. “Basel III” refers to various documents released by the Basel Committee on Banking Supervision. For the Company and the Bank, the general effective date of the rules was January 1, 2015, and, for certain provisions, various phase-in periods and later effective dates apply. The chief features of these rules are summarized below.

The rules refine the definitions of what constitutes regulatory capital and add a new regulatory capital element, common equity Tier 1 capital. The minimum capital ratios are (i) a common equity Tier 1 (“CET1”) risk-based capital ratio of 4.5%; (ii) a Tier 1 risk-based capital ratio of 6%; (iii) a total risk-based capital ratio of 8%; and (iv) a Tier 1 leverage ratio of 4%. In addition to the minimum capital ratios, the rules include a capital conservation buffer, under which a banking organization must have CET1 more than 2.5% above each of its minimum risk-based capital ratios in order to avoid restrictions on paying dividends, repurchasing shares, and paying certain discretionary bonuses. The capital conservation buffer became fully implemented on January 1, 2019.

These rules also revised the prompt corrective action framework, which is designed to place restrictions on insured depository institutions if their capital levels show signs of weakness. Under the revised prompt corrective action requirements, insured depository institutions are required to meet the following in order to qualify as “well capitalized:” (i) a common equity Tier 1 risk-based capital ratio of at least 6.5%, (ii) a Tier 1 risk-based capital ratio of at least 8%, (iii) a total risk-based capital ratio of at least 10% and (iv) a Tier 1 leverage ratio of 5%, and must not be subject to an order, agreement or directive mandating a specific capital level.

Economic Growth Act. In May 2018, the Economic Growth, Regulatory Relief, and Consumer Protection Act (the “Economic Growth Act”), was enacted to modify or eliminate certain financial reform rules and regulations, including some implemented under the Dodd-Frank Act. While the Economic Growth Act maintains most of the regulatory structure established by the Dodd-Frank Act, it amends certain aspects of the regulatory framework for small depository institutions with assets of less than $10 billion and for large banks with assets of more than $50 billion. Many of these amendments could result in meaningful regulatory changes.

The Economic Growth Act, among other matters, expands the definition of qualified mortgages which may be held by a financial institution and simplifies the regulatory capital rules for financial institutions and their holding companies with total consolidated assets of less than $10 billion by instructing the federal banking regulators to establish a single “Community Bank Leverage Ratio” (“CBLR”) of between 8 and 10 percent. Upon election, any qualifying depository institution or its holding company that exceeds the CBLR will be considered to have met generally applicable leverage and risk-based regulatory capital requirements and any qualifying depository institution that exceeds the CBLR will be considered “well-capitalized” under the prompt corrective action rules. Currently, the CBLR is 9.0%. To date, the Company and the Bank have chosen to not utilize the CBLR due to the Company’s size and complexity, including its commercial real estate and construction lending concentrations and significant off-balance sheet funding commitments.

In addition, the Economic Growth Act includes regulatory relief in the areas of examination cycles, call reports, mortgage disclosures and risk weights for certain high-risk commercial real estate loans.

Business Initiatives

Since early 2022, Great Southern had been preparing to convert to a new core banking platform (New System) to be delivered by a third-party vendor. As previously disclosed, the migration to the New System, originally scheduled for the third quarter of 2023, was delayed to mid-2024. In addition, as also previously disclosed, certain contractual disputes arose between Great Southern and the third-party vendor. While discussions were ongoing between the parties for an extended period of time, no meaningful progress was made in resolving the contractual disputes.

​

The system migration efforts were beset by a variety of significant issues, including having missed a second conversion date because of continued operational and system problems. Therefore, Great Southern has taken the following actions to protect its interests. On April 24, 2024, Great Southern informed the third-party vendor that it was terminating the Master Agreement between Great Southern and the third-party vendor in accordance with Great Southern’s rights under the Master Agreement. In addition, on April 24, 2024, Great Southern initiated legal action against the third-party vendor by filing a complaint in the U.S. District Court for the Western District of Missouri, Southern Division. The complaint seeks to recover damages caused by the third-party vendor’s material breach of the Master Agreement, inability and/or inaction on the part of the third-party vendor to effectively and timely manage the system migration, as well as the third-party vendor’s misrepresentations and omissions. As of the filing date of this Quarterly Report on Form 10-Q, the third-party vendor has not yet filed a responsive pleading to Great Southern’s complaint. The parties continue informal settlement discussions, but there is no guarantee that the parties will reach a mutually agreed upon settlement to terminate the litigation.

​

Great Southern now expects to continue operations with its current core banking provider, which will allow Great Southern to offer its full array of products and services.

Comparison of Financial Condition at June 30, 2024 and December 31, 2023

During the six months ended June 30, 2024, the Company’s total assets increased by $146.4 million to $5.96 billion. The increase was primarily in investment securities and loans, partially offset by a decrease in cash and cash equivalents.

Cash and cash equivalents were $186.5 million at June 30, 2024, a decrease of $24.9 million, or 11.8%, from $211.3 million at December 31, 2023.

The Company’s available-for-sale securities increased $70.9 million, or 14.8%, compared to December 31, 2023. The increase was primarily due to the purchase of several collateralized mortgage obligations and mortgage-backed securities, partially offset by normal monthly payments received related to the portfolio of mortgage-backed securities and collateralized mortgage obligations. The available-for-sale securities portfolio was 9.2% and 8.2% of total assets at June 30, 2024 and December 31, 2023, respectively.

The Company’s held-to-maturity securities decreased $3.8 million, or 1.9%, compared to December 31, 2023. The decrease was primarily due to normal monthly payments received related to the portfolio of mortgage-backed securities and collateralized mortgage obligations. The held-to-maturity securities portfolio was 3.2% and 3.4% of total assets at June 30, 2024 and December 31, 2023, respectively.

Net loans increased $44.0 million from December 31, 2023, to $4.63 billion at June 30, 2024. This increase was primarily in other residential (multi-family) loans ($309 million increase), which was partially offset by a decrease in construction loans ($162 million decrease) and commercial business loans ($62 million decrease). The decrease in commercial business loans was primarily related to a few large loan payoffs in the three months ended March 31, 2024. Despite the decrease in construction loans, the pipeline of construction loan commitments and the unfunded portion of construction loans remained strong in the six months ending June 30, 2024. As construction projects were completed, the related loans were either moved from the construction category to the appropriate permanent loan categories or paid off.

Total liabilities increased $149.4 million, from $5.24 billion at December 31, 2023 to $5.39 billion at June 30, 2024. This increase was primarily due to an increase in short-term borrowings, partially offset by a reduction in transaction account deposits and certificate of deposit accounts.

Total deposits decreased $106.4 million, or 2.3%, from $4.72 billion at December 31, 2023 to $4.62 billion at June 30, 2024. Transaction account balances decreased $50.7 million, from $3.11 billion at December 31, 2023 to $3.06 billion at June 30, 2024. Total interest-bearing checking accounts decreased $25.5 million, while non-interest-bearing checking accounts decreased $25.3 million. Retail certificates of deposit decreased $64.2 million compared to December 31, 2023, to $884.0 million at June 30, 2024 due to competition for deposits.

48

​

Brokered deposits increased $8.5 million to $670.0 million at June 30, 2024, compared to $661.5 million at December 31, 2023. Brokered deposits were utilized to offset reductions in other deposit categories and in borrowings. The Company has the capacity to further expand its use of brokered deposits if it chooses to do so. Of the total brokered deposits at June 30, 2024, $300.0 million were floating rate deposits, which adjust daily, based on the effective federal funds rate index.

The Company’s term FHLBank advances were $-0- at both June 30, 2024 and December 31, 2023. At June 30, 2024 and December 31, 2023, there were no borrowings from the FHLBank, other than overnight borrowings, which are included in the short-term borrowings category. The Company may utilize both overnight borrowings and short-term FHLBank advances depending on relative interest rates.

Short-term borrowings and other interest-bearing liabilities increased $223.7 million from $252.6 million at December 31, 2023 to $476.3 million at June 30, 2024. At June 30, 2024, $295.0 million of this total was overnight borrowings from the FHLBank, which was used to fund loan originations and purchases of investment securities, compared to $251.0 million of overnight borrowings from the FHLBank at December 31, 2023. In January 2024, the Bank borrowed $180.0 million under the BTFP. The BTFP borrowing, which matures in January 2025 and has a fixed interest rate of 4.83%, may be repaid in full or in part without penalty prior to its stated maturity date. The line is secured primarily by the Bank’s held-to-maturity investment securities, with assets pledged totaling approximately $191.3 million as of June 30, 2024. These funds were primarily used to repay a portion of the Bank’s overnight borrowings from the FHLBank.

Securities sold under reverse repurchase agreements with customers increased $3.4 million, or 4.7%, from $70.8 million at December 31, 2023 to $74.2 million at June 30, 2024. These balances fluctuate over time based on customer demand for this product.

Total stockholders’ equity decreased $3.0 million, from $571.8 million at December 31, 2023 to $568.8 million at June 30, 2024. Accumulated other comprehensive loss (a reduction in equity) increased $13.0 million during the six months ended June 30, 2024, primarily due to decreases in the fair value of available-for-sale investment securities and the fair value of cash flow hedges, as a result of increased market interest rates. Stockholders’ equity decreased due to repurchases of the Company’s common stock totaling $12.4 million and dividends declared on common stock of $9.3 million. Partially offsetting these decreases were net income of $30.4 million for the six months ended June 30, 2024 and a $1.4 million increase in stockholders’ equity due to stock option exercises.

Results of Operations and Comparison for the Three and Six Months Ended June 30, 2024 and 2023

General

Net income was $17.0 million for the three months ended June 30, 2024 compared to $18.3 million for the three months ended June 30, 2023. This decrease of $1.3 million, or 7.3%, was primarily due to a decrease in net interest income of $1.3 million, or 2.7%, an increase in non-interest expense of $1.7 million, or 4.9% and an increase in provision for credit losses on unfunded commitments of $1.0 million, or 62.5%, partially offset by an increase in non-interest income of $2.1 million, or 26.6%, and a decrease in income tax expense of $627,000, or 14.0%.

Net income was $30.4 million for the six months ended June 30, 2024 compared to $38.8 million for the six months ended June 30, 2023. This decrease of $8.4 million, or 21.6%, was primarily due to a decrease in net interest income of $9.7 million, or 9.6%, an increase in non-interest expense of $1.7 million, or 2.4%, and an increase in provision for credit losses on loans and unfunded commitments of $968,000, or 102.4%. The provision for credit losses on loans decreased $1.0 million, while the provision for credit losses on unfunded commitments increased $2.0 million. These items were partially offset by a decrease in income tax expense of $3.0 million, or 29.6%, and an increase in non-interest income of $981,000, or 6.3%.

Total Interest Income

Total interest income increased $7.3 million, or 9.9%, during the three months ended June 30, 2024 compared to the three months ended June 30, 2023. The increase was due to a $6.9 million increase in interest income on loans and a $456,000 increase in interest income on investment securities and other interest-earning assets. Interest income from loans increased during the three months ended June 30, 2024 compared to the same period in 2023 due to higher average balances and higher average rates of interest. Interest income from investment securities and other interest-earning assets increased during the three months ended June 30, 2024 compared to the same period in 2023 due to higher average rates of interest.

Total interest income increased $13.2 million, or 9.1%, during the six months ended June 30, 2024 compared to the six months ended June 30, 2023. The increase was due to a $12.5 million increase in interest income on loans and a $745,000 increase in interest income on investment securities and other interest-earning assets. Interest income from loans increased during the six months ended June 30,

49

​

2024 compared to the same period in 2023 due to higher average balances and higher average rates of interest. Interest income from investment securities and other interest-earning assets increased during the six months ended June 30, 2024 compared to the same period in 2023 due to higher average rates of interest, partially offset by slightly lower average balances of investment securities.

Interest Income – Loans

During the three months ended June 30, 2024 compared to the three months ended June 30, 2023, interest income on loans increased $6.0 million due to higher average interest rates on loans. The average yield on loans increased from 5.84% during the three months ended June 30, 2023, to 6.37% during the three months ended June 30, 2024. This increase was primarily due to the repricing of floating rate loans as market interest rates increased. Interest income on loans also increased $834,000 as the result of higher average loan balances, which increased from $4.63 billion during the three months ended June 30, 2023, to $4.69 billion during the three months ended June 30, 2024. Since the end of 2022, loan originations and net loan growth have been muted; however, some loan growth has come as a result of the funding of previously approved but unfunded balances on construction loans and a slowdown in loan prepayments in 2023 and 2024, due to higher market interest rates.

During the six months ended June 30, 2024 compared to the six months ended June 30, 2023, interest income on loans increased $10.8 million due to higher average interest rates on loans. The average yield on loans increased from 5.80% during the six months ended June 30, 2023, to 6.25% during the six months ended June 30, 2024. This increase was primarily due to the repricing of floating rate loans due to higher market interest rates. Interest income on loans also increased $1.7 million as the result of higher average loan balances, which increased from $4.62 billion during the six months ended June 30, 2023, to $4.68 billion during the six months ended June 30, 2024.

In October 2018, the Company entered into an interest rate swap transaction as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of the swap was $400 million with a contractual termination date in October 2025. As previously disclosed by the Company, in March 2020, the Company and its swap counterparty mutually agreed to terminate this swap, effective immediately. The Company was paid $45.9 million, including accrued but unpaid interest, from its swap counterparty as a result of this termination. This $45.9 million, less the accrued to date interest portion and net of deferred income taxes, is reflected in the Company’s stockholders’ equity as Accumulated Other Comprehensive Income (AOCI) and is being accreted to interest income on loans monthly through the original contractual termination date of October 6, 2025. This has had the effect of reducing AOCI and increasing Net Interest Income and Retained Earnings over the periods. The Company recorded interest income related to the interest rate swap of $2.0 million in each of the three months ended June 30, 2024 and 2023. The Company recorded $4.1 million of interest income related to the swap in the six months ended June 30, 2024 and $4.0 million of interest income related to the swap in the six months ended June 30, 2023. At June 30, 2024, the Company expected to have a sufficient amount of eligible variable rate loans to continue to accrete this interest income ratably in future periods. If this expectation changes and the amount of eligible variable rate loans decreases significantly, the Company may be required to recognize this interest income more rapidly.

In March 2022, the Company entered into another interest rate swap transaction as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of the swap was $300 million, with a contractual termination date of March 1, 2024. Under the terms of the swap, the Company received a fixed rate of interest of 1.6725% and paid a floating rate of interest equal to one-month USD-LIBOR (or the equivalent replacement USD-SOFR rate once USD-LIBOR rate ceased to be available). The floating rate was reset monthly and net settlements of interest due to/from the counterparty also occurred monthly. To the extent that the fixed rate exceeded one-month USD-LIBOR/SOFR, the Company received net interest settlements, which were recorded as loan interest income. If one-month USD-LIBOR/SOFR exceeded the fixed rate of interest, the Company paid net settlements to the counterparty and recorded those net payments as a reduction of interest income on loans. The Company recorded a reduction of loan interest income related to this swap transaction of $1.9 million in the six months ended June 30, 2024. The Company recorded a reduction of loan interest income related to this swap transaction of $2.6 million and $4.7 million, respectively, in the three and six months ended June 30, 2023. As this interest rate swap reached its contractual termination date of March 1, 2024, there was no impact from this swap in the three months ended June 30, 2024, and there will be no further interest income impact related to this swap.

In July 2022, the Company entered into two additional interest rate swap transactions as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of each swap is $200 million with an effective date of May 1, 2023 and a termination date of May 1, 2028. Under the terms of one swap, the Company receives a fixed rate of interest of 2.628% and pays a floating rate of interest equal to one-month USD-SOFR OIS. Under the terms of the other swap, the Company receives a fixed rate of interest of 5.725% and pays a floating rate of interest equal to one-month USD-Prime. In each case, the floating rate resets monthly and net settlements of interest due to/from the counterparty also occur monthly. To the extent the fixed rate of interest exceeds the floating rate of interest, the Company receives net interest settlements, which are recorded as loan interest income. If the floating rate of interest exceeds the fixed rate of interest, the Company pays net settlements to the counterparty and records those net

50

​

payments as a reduction of interest income on loans. The Company recorded a reduction of loan interest income related to these swap transactions of $2.8 million in the three months ended June 30, 2024, compared to a $1.7 million reduction of interest income in the three months ended June 30, 2023. The Company recorded a reduction of loan interest income related to these swap transactions of $5.5 million in the six months ended June 30, 2024, compared to a $1.7 million reduction of interest income in the the six months ended June 30, 2023. At June 30, 2024, the USD-Prime rate was 8.50% and the one-month USD-SOFR OIS rate was 5.33643%.

If market interest rates remain near their current levels, the Company’s interest rate swaps will continue to have a negative impact on net interest income.

Interest Income – Investments and Other Interest-earning Assets

Interest income on investments increased $364,000 in the three months ended June 30, 2024 compared to the three months ended June 30, 2023.

51

​

higher in the 2024 period due to significant increases in overall market rates and competition for deposits. Interest expense on demand deposits increased $127,000, due to an increase in average balances from $2.19 billion during the three months ended June 30, 2023, to $2.23 billion during the three months ended June 30, 2024. The Company also experienced increased balances in various types of money market accounts due to the increase in average rates on these accounts.

Interest expense on time deposits increased $2.6 million as a result of an increase in average rates of interest from 2.85% during the three months ended June 30, 2023, to 4.08% during the three months ended June 30, 2024. Partially offsetting this increase, interest expense on time deposits decreased $575,000 due to a decrease in average balances of time deposits from $987.5 million during the three months ended June 30, 2023 to $894.5 million in the three months ended June 30, 2024. A large portion of the Company’s certificate of deposit portfolio matures within six to twelve months and therefore reprices fairly quickly; this is consistent with the portfolio over the past several years. Competition for time deposits remains significant in our market areas, and upon maturity, we lost some of these deposits to competitors. Older certificates of deposit that renewed or were replaced with new deposits generally resulted in the Company paying a higher rate of interest compared to the year-ago period due to increases in market interest rates and targeted promotions during 2023 and into 2024.

Interest expense on time deposits increased $7.0 million as a result of an increase in average rates of interest from 2.46% during the six months ended June 30, 2023, to 4.00% during the six months ended June 30, 2024.

As noted above, a large portion of the Company’s certificate of deposit portfolio matures within six to twelve months and therefore reprices fairly quickly. Older certificates of deposit that renewed or were replaced with new deposits generally resulted in the Company paying a higher rate of interest compared to the year-ago period due to increases in market interest rates and targeted promotions during 2023 and into 2024.

Interest expense on brokered deposits increased $571,000, due to an increase in average balances from $637.6 million during the three months ended June 30, 2023 to $683.3 million during the three months ended June 30, 2024.

Interest expense on reverse repurchase agreements increased $72,000 due to higher average interest rates during the three months ended June 30, 2024 when compared to the three months ended June 30, 2023. The average rate of interest was 1.60% for the three months ended June 30, 2023 compared to 2.06% for the three months ended June 30, 2024, due to higher market interest rates.

Interest expense on reverse repurchase agreements increased $252,000 due to higher average interest rates during the six months ended June 30, 2024 when compared to the six months ended June 30, 2023. The average rate of interest was 1.12% for the six months ended June 30, 2023 compared to 1.93% for the six months ended June 30, 2024, due to higher market interest rates. Partially offsetting this increase, interest expense on reverse repurchase agreements decreased $88,000 due to lower average balances.

The average rate of interest was 5.24% for the three months ended June 30, 2023, compared to 5.18% for the three months ended June 30, 2024. The decrease in the average rate of interest was primarily due to the 2024 period including the BTFP borrowing, which had a lower rate of interest than the FHLB overnight borrowings.

Interest expense on short-term borrowings (including overnight borrowings from the FHLBank and BTFP borrowings from FRBSTL) and other interest-bearing liabilities increased $3.6 million during the six months ended June 30, 2024 when compared to the six months ended June 30, 2023 due to higher average balances.

The average interest rate was 7.08% in the three months ended June 30, 2024 compared to 6.63% in the three months ended June 30, 2023. The subordinated debentures are variable-rate debentures, which bear interest at an average rate of three-month SOFR (originally LIBOR), plus 1.60%, adjusting quarterly, which was 7.19% at June 30, 2024. There was no change in the average balance of the subordinated debentures between the 2023 and 2024 three-month periods.

​

In June 2020, the Company issued $75.0 million of 5.50% fixed-to-floating rate subordinated notes due June 15, 2030. The notes were sold at par, resulting in net proceeds, after underwriting discounts and commissions and other issuance costs, of approximately $73.5 million. These issuance costs are amortized over the expected life of the notes, which is five years from the issuance date, impacting the overall interest expense on the notes. There was no change in the interest expense on subordinated notes during the three or six months ended June 30, 2024, compared to the three and six months ended June 30, 2023.

Net Interest Income

Net interest income for the three months ended June 30, 2024 decreased $1.3 million to $46.8 million compared to $48.1 million for the three months ended June 30, 2023. Net interest margin was 3.43% in the three months ended June 30, 2024, compared to 3.56% in the three months ended June 30, 2023, a decrease of 13 basis points, or 3.7%. The Company experienced increases in interest income on both loans and investment securities. The Company experienced increases in interest expense on deposits, short-term borrowings, subordinated debentures issued to capital trust and securities sold under reverse repurchase agreements with customers.

Net interest income for the six months ended June 30, 2024 decreased $9.7 million to $91.6 million compared to $101.3 million for the six months ended June 30, 2023. Net interest margin was 3.38% in the six months ended June 30, 2024, compared to 3.77% in the six months ended June 30, 2023, a decrease of 39 basis points, or 10.3%. The Company experienced increases in interest income on both loans and investment securities. The Company experienced increases in interest expense on deposits, short-term borrowings, subordinated debentures issued to capital trust and securities sold under reverse repurchase agreements with customers.

The Company’s overall average interest rate spread decreased 19 basis points, or 6.6%, from 2.96% during the three months ended June 30, 2023 to 2.77% during the three months ended June 30, 2024. The decrease was due to a 69 basis point increase in the weighted average rate paid on interest-bearing liabilities, partially offset by a 50 basis point increase in the weighted average yield earned on interest-earning assets. In comparing the two periods, the yield on loans increased 53 basis points, the yield on investment securities increased 23 basis points and the yield on other interest-earning assets increased 38 basis points. The rate paid on deposits increased 64 basis points, the rate paid on reverse repurchase agreements increased 46 basis points, the rate paid on short-term borrowings and other interest-bearing liabilities decreased 6 basis points and the rate paid on subordinated debentures issued to capital trust increased 45 basis points. Interest rates earned on loans and paid on deposits are affected by the mix of the loan and deposit portfolios, the stated maturity of loans and time deposits, the amount of fixed-rate and variable-rate loans and other repricing characteristics. In 2023, overall competition for deposits intensified as a few banks experienced significant liquidity issues in March and April 2023 and market rates moved higher more rapidly. Overall competition for deposits has remained elevated in 2024 and market interest rates have remained higher in 2024.

The Company’s overall average interest rate spread decreased 53 basis points, or 16.4%, from 3.24% during the six months ended June 30, 2023 to 2.71% during the six months ended June 30, 2024. The decrease was due to a 96 basis point increase in the weighted average rate paid on interest-bearing liabilities, partially offset by a 43 basis point increase in the weighted average yield earned on interest-earning assets. In comparing the two periods, the yield on loans increased 45 basis points, the yield on investment securities increased 19 basis points and the yield on other interest-earning assets increased 53 basis points. The rate paid on deposits increased 95 basis points, the rate paid on reverse repurchase agreements increased 81 basis points, the rate paid on short-term borrowings and other interest-bearing liabilities increased 14 basis points and the rate paid on subordinated debentures issued to capital trust increased 67 basis points.

Provision for and Allowance for Credit Losses

Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as changes in underwriting standards, portfolio mix, delinquency level or term, as well as for changes in economic conditions, including but not limited to, changes in the national unemployment rate, commercial real estate price index, consumer sentiment, gross domestic product (GDP) and construction spending.

Challenging or worsening economic conditions from higher inflation or interest rates, COVID-19 and subsequent variant outbreaks or similar events, global unrest or other factors may lead to increased losses in the portfolio and/or requirements for an increase in provision expense. Management maintains various controls in an attempt to identify and limit future losses, such as a watch list of problem loans and potential problem loans, documented loan administration policies and loan review staff to review the quality and

54

​

anticipated collectability of the portfolio. Additional procedures provide for frequent management review of the loan portfolio based on loan size, loan type, delinquencies, financial analysis, ongoing correspondence with borrowers and problem loan workouts. Management determines which loans are collateral-dependent, evaluates risk of loss and makes additional provisions to expense, if necessary, to maintain the allowance at a satisfactory level.

During the three months ended June 30, 2024 and June 30, 2023, the Company did not record a provision expense on its portfolio of outstanding loans. During the six months ended June 30, 2024, the Company recorded provision expense of $500,000 on its portfolio of outstanding loans. During the six months ended June 30, 2023, the Company recorded provision expense of $1.5 million on its portfolio of outstanding loans. Total net recoveries were $168,000 for the three months ended June 30, 2024, compared to net charge-offs of $135,000 in the three months ended June 30, 2023. Total net recoveries were $85,000 for the six months ended June 30, 2024, compared to net charge-offs of $128,000 in the six months ended June 30, 2023. The provision for losses on unfunded commitments for the three months ended June 30, 2024 was a negative provision of $607,000, compared to a negative provision of $1.6 million for the three months ended June 30, 2023. The provision for losses on unfunded commitments for the six months ended June 30, 2024 was a negative provision of $477,000, compared to a negative provision of $2.4 million for the six months ended June 30, 2023. The level and mix of unfunded commitments resulted in a decrease in the required reserve for such potential losses. General market conditions and unique circumstances related to specific industries and individual projects contribute to the determination of the level of provisions and charge-offs in each period.

The Bank’s allowance for credit losses as a percentage of total loans was 1.39% at both June 30, 2024 and December 31, 2023. Management considers the allowance for credit losses adequate to cover losses inherent in the Bank’s loan portfolio at June 30, 2024, based on recent reviews of the Bank’s loan portfolio and current economic conditions. If challenging economic conditions were to last longer than anticipated or deteriorate further, or if management’s assessment of the loan portfolio were to change, additional loan loss provisions could be required, thereby adversely affecting the Company’s future results of operations and financial condition.

Non-performing Assets

As a result of changes in loan portfolio composition, changes in economic and market conditions and other factors specific to a borrower’s circumstances, the level of non-performing assets will fluctuate.

At June 30, 2024, non-performing assets were $20.4 million, an increase of $8.6 million from $11.8 million at December 31, 2023. Non-performing assets as a percentage of total assets were 0.34% at June 30, 2024, compared to 0.20% at December 31, 2023. One loan relationship, totaling $9.3 million, was transferred from non-performing loans to foreclosed assets held for sale in the three months ended June 30, 2024.

Compared to December 31, 2023, non-performing loans decreased $765,000, to $11.0 million at June 30, 2024. The majority of this decrease was in the non-performing commercial real estate loans category, which decreased $788,000 from December 31, 2023.

Compared to December 31, 2023, foreclosed assets increased $9.4 million to $9.4 million at June 30, 2024. Nearly all of this increase was in the other residential (multi-family) loans category, which increased $9.3 million from December 31, 2023.

At June 30, 2024, the non-performing commercial real estate category included five loans, three of which were added during the current period. The largest relationship in the category, which totaled $7.2 million, or 73.5% of the total category, was added to non-performing loans during the second quarter of 2023 and is collateralized by an office building in Missouri. The balance of this relationship was reduced by payments of $883,000 during the six months ended June 30, 2024. Another loan, totaling $2.4 million, which was a purchased participation loan originally obtained through an FDIC-assisted acquisition, is collateralized by a low-income assisted living facility in Wisconsin. During the first quarter of 2024, the Company purchased the lead participant’s $220,000 interest in this note, resulting in a 66% ownership interest. The other residential (multi-family) category of non-performing loans consisted of one student housing project in Texas, which was added to this category during the first quarter of 2024 and transferred to foreclosed assets during the three months ended June 30, 2024. The non-performing one- to four-family residential category included three loans. The largest relationship in the category totaled $593,000, or 51.7% of the category, and was added in the current period. The non-performing consumer category included five loans, three of which were added during the current period.

Potential Problem Loans. Potential problem loans decreased $1.8 million, to $5.6 million at June 30, 2024 from $7.4 million at December 31, 2023. The decrease during the period was primarily due to a $7.2 million loan in the other residential (multi-family) category that paid off during the period, partially offset by the addition of one loan relationship totaling $4.9 million ($4.4 million in the commercial real estate category and $498,000 in the consumer category) during the six months ended June 30, 2024. Potential problem loans are loans which management has identified through routine internal review procedures as having possible credit problems that may cause the borrowers difficulty in complying with the current repayment terms. These loans are not reflected in non-performing assets.

Activity in the potential problem loans category during the six months ended June 30, 2024 was as follows:

​

At June 30, 2024, the commercial real estate category of potential problem loans included three loans, all of which are part of one relationship and were added during the current period. This relationship is collateralized by three nursing care facilities located in southwest Missouri. The borrower’s business cash flow was negatively impacted by a labor shortage and a decrease in Medicaid reimbursement during 2022-2023. Monthly payments were made prior to and continued to be made after the transfer to this category. The one- to four-family residential category of potential problem loans included five loans, four of which were added during the current period. The largest relationship in this category totaled $98,000, or 29.9% of the total category. The commercial business category of potential problem loans included two loans. The largest relationship in this category totaled $200,000, or 96.5% of the total category, and was added during the current period. The consumer category of potential problem loans included 11 loans, nine of which were added during the current period, including one home equity loan totaling $498,000 that is related to the nursing care facility relationship noted above. The decrease in the other residential (multi-family) category of potential problem loans included the payment in full in April 2024 of one $7.2 million loan relationship that was collateralized by an apartment and retail project in Oklahoma.

Other Real Estate Owned and Repossessions. All of the total $9.4 million of other real estate owned and repossessions at June 30, 2024 were acquired through foreclosure.

​

At June 30, 2024, the land development category of foreclosed assets consisted of one property in southern Illinois, which was transferred from non-performing loans during the six months ended June 30, 2024. The other residential (multi-family) category of foreclosed assets included one property consisting of student housing in Texas, which was added during the six months ended June 30, 2024. The additions and sales in the consumer category were due to the volume of repossessions of automobiles, which generally are subject to a shorter repossession process.

Loans Classified “Watch” and “Special Mention”

The Company reviews the credit quality of its loan portfolio using an internal grading system that classifies loans as “Satisfactory,” “Watch,” “Special Mention,” “Substandard” and “Doubtful.” Multiple loan reviews take place on a continuous basis by credit risk and lending management. Reviews are focused on financial performance, occupancy trends, delinquency status, covenant compliance, collateral support, economic considerations and various other factors. Loans classified as “Watch” are being monitored due to indications of potential weaknesses or deficiencies that may require future reclassification as special mention or substandard. Loans classified as “Watch” decreased $1.0 million, from $8.3 million at December 31, 2023 to $7.3 million at June 30, 2024, primarily due to the payoff of a single $1.4 million loan. While loans classified as “Special Mention” are not adversely classified, they are deserving of management’s close attention to ensure repayment prospects and that the credit position of the assets does not deteriorate and expose the institution to elevated risk, which might warrant adverse classification at a future date. In the six months ended June 30, 2024, loans classified as “Special Mention” decreased $7.9 million, to $18.7 million, as two loan relationships were downgraded to “Substandard” and added to non-performing loans. The largest relationship consisted of four commercial business loans totaling $16.0 million at June 30, 2024 and is secured by business assets, equipment, accounts receivable and real estate. The relationship was added to the “Special Mention” category during 2023 due to stressed cash flow associated with business expansion. Since that time, the borrower has reduced debt by restructuring business operations, resulting in improved business cash flow and collateral margins. See Note 6 “Loans and Allowance for Credit Losses” in the Notes to Consolidated Financial Statements included in this report for further discussion of the Company’s loan grading system.

Non-interest Income

For the three months ended June 30, 2024, non-interest income increased $2.1 million to $9.8 million when compared to the three months ended June 30, 2023, primarily as a result of the following items:

Other income: Other income increased $2.6 million compared to the prior year period. In the three months ended June 30, 2024, the Company recorded $2.7 million of other income, net of expenses and write-offs, related to the termination of the Master Agreement between the Company and a third-party software vendor for the conversion of the Company’s core banking platform. This termination was previously disclosed in the Company’s Quarterly Report on Form 10-Q for the quarterly period ended March 31, 2024. This amount represented the elimination of certain deferred credits and other liabilities, along with the write-off of certain capitalized hardware, software and other assets, that previously had been recorded as part of the preparation to convert to the new core-banking platform.

Net gains on loan sales: Net gains on loan sales increased $418,000 compared to the prior year period. The increase was partially due to an increase in balance of fixed-rate single-family mortgage loans sold during the 2024 period compared to the 2023 period. Fixed rate single-family mortgage loans originated are generally subsequently sold in the secondary market. The Company realized higher

57

​

premiums on the sales of loans in the 2024 period compared to the 2023 period, as market interest rates were more stable in the first half of 2024 compared to the first half of 2023.

Overdraft and insufficient funds fees: Overdraft and insufficient funds fees decreased $759,000 compared to the prior year period. This decrease was primarily due to the continuation of a multi-year trend whereby our customers are choosing to forego authorizing payments of certain items which exceed their account balances, resulting in fewer overdrafts in checking accounts and related fees. We expect these fees generally to continue to decrease in the future.

For the six months ended June 30, 2024, non-interest income increased $981,000 to $16.6 million when compared to the six months ended June 30, 2023, primarily as a result of the following items:

Other income: Other income increased $2.1 million compared to the prior year period, for the same reason noted in the quarterly comparison above.

Net gains on loan sales: Net gains on loan sales increased $706,000 compared to the prior year period, for the same reason noted in the quarterly comparison above.

Overdraft and insufficient funds fees: Overdraft and insufficient funds fees decreased $1.4 million compared to the prior year period, for the same reason noted in the quarterly comparison above.

Point-of-sale and ATM fees: Point-of-sale and ATM fees decreased $709,000 compared to the prior year period. This decrease was primarily due to a portion of these transactions now being routed through channels with lower fees to us, which we expect will continue in future periods, and slightly lower usage of debit cards by our customers.

Non-interest Expense

For the three months ended June 30, 2024, non-interest expense increased $1.7 million to $36.4 million when compared to the three months ended June 30, 2023, primarily as a result of the following items:

Other operating expenses: Other operating expenses increased $466,000 from the prior year period, to $2.6 million. In the 2024 period, the Company recorded expenses totaling $600,000 related to ongoing compliance matters. The Company continually monitors its compliance programs, including matters that may arise from time to time, which could result in additional compliance expenses in future periods.

Net occupancy expenses: Net occupancy expenses increased $432,000 from the prior year period. Various components of computer license and support expenses collectively increased by $476,000 in the 2024 period compared to the 2023 period.

Several other non-interest expense categories increased $916,000 in total compared to the prior year period.

For the six months ended June 30, 2024, non-interest expense increased $1.7 million to $70.8 million when compared to the six months ended June 30, 2023, primarily as a result of the following items:

Salaries and employee benefits: Salaries and employee benefits expense increased $661,000, a 1.7% increase, from the prior year period. Much of this increase related to normal annual merit increases in various lending and operations areas.

Net occupancy expenses: Net occupancy expenses increased $551,000 from the prior year period, for the same reason noted in the quarterly comparison above.

Insurance: Insurance expense increased $530,000 from the prior year period. The increase was primarily due to increases in deposit insurance rates for the FDIC’s Deposit Insurance Fund, which went into effect during 2023.

The Company’s efficiency ratio for the three months ended June 30, 2024, was 64.27% compared to 62.10% for the same period in 2023. The Company’s efficiency ratio for the six months ended June 30, 2024, was 65.42% compared to 59.13% for the same period in 2023. The Company’s ratio of non-interest expense to average assets was 2.50% and 2.44% for the three- and six-months ended June 30, 2024, respectively, compared to 2.43% and 2.42% for the three- and six-months ended June 30, 2023, respectively. Average assets for the three months ended June 30, 2024, increased $110.2 million, or 1.9%, from the three months ended June 30, 2023, primarily due to an increase in net loans receivable and non-interest-earning assets. Average assets for the six months ended June 30,

58

​

2024, increased $84.0 million, or 1.5%, compared to the six months ended June 30, 2023, primarily due to increases in net loans receivable and non-interest-earning assets.

Provision for Income Taxes

For the three months ended June 30, 2024 and 2023, the Company’s effective tax rate was 18.5% and 19.7%, respectively. For the six months ended June 30, 2024 and 2023, the Company’s effective tax rate was 18.8% and 20.5%, respectively. These effective rates were near or below the statutory federal tax rate of 21%, due primarily to the utilization of certain investment tax credits and the Company’s tax-exempt investments and tax-exempt loans, which reduced the Company’s effective tax rate. The Company’s effective tax rate may fluctuate in future periods as it is impacted by the level and timing of the Company’s utilization of tax credits, the level of tax-exempt investments and loans, the amount of taxable income in various state jurisdictions and the overall level of pre-tax income. State tax expense estimates continually evolve as taxable income and apportionment between states is analyzed. The Company currently expects its effective tax rate (combined federal and state) will be approximately 18.5% to 20.0% in future periods, primarily due to additional investment tax credits being utilized beginning in 2024.

Average Balances, Interest Rates and Yields

​

The following tables present, for the periods indicated, the total dollar amount of interest income from average interest-earning assets and the resulting yields, as well as the interest expense on average interest-bearing liabilities, expressed both in dollars and rates, and the net interest margin. Average balances of loans receivable include the average balances of non-accrual loans for each period. Interest income on loans includes interest received on non-accrual loans on a cash basis. Interest income on loans also includes the amortization of net loan fees which were deferred in accordance with accounting standards. Net loan fees included in interest income were $1.1 million and $1.5 million for the three months ended June 30, 2024 and 2023, respectively. Net loan fees included in interest income were $2.3 million and $2.9 million for the six months ended June 30, 2024 and 2023, respectively. Tax-exempt income was not calculated on a tax equivalent basis. The table does not reflect any effect of income taxes.

Rate/Volume Analysis

The following tables present the dollar amounts of changes in interest income and interest expense for major components of interest-earning assets and interest-bearing liabilities for the periods shown. For each category of interest-earning assets and interest-bearing liabilities, information is provided on changes attributable to (i) changes in rate (i.e., changes in rate multiplied by old volume) and (ii) changes in volume (i.e., changes in volume multiplied by old rate). For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately to volume and rate. Tax-exempt income was not calculated on a tax equivalent basis.

Liquidity

Liquidity is a measure of the Company’s ability to generate sufficient cash to meet present and future financial obligations in a timely manner through either the sale or maturity of existing assets or the acquisition of additional funds through liability management. These obligations include the credit needs of customers, funding deposit withdrawals, and the day-to-day operations of the Company. Liquid assets include cash, interest-bearing deposits with financial institutions and certain investment securities and loans. As a result of the Company’s ability to generate liquidity primarily through liability funding, management believes that the Company maintains overall liquidity sufficient to satisfy its depositors’ requirements and meet its borrowers’ credit needs. At June 30, 2024, the Company had commitments of approximately $32.6 million to fund loan originations, $1.09 billion of unused lines of credit and unadvanced loans, and $12.5 million of outstanding letters of credit.

Loan commitments and the unfunded portion of loans at the dates indicated were as follows (In Thousands):

The Company’s primary sources of funds are customer deposits, brokered deposits, short-term borrowings at the FHLBank, other borrowings, loan repayments, unpledged securities, proceeds from sales of loans and available-for-sale securities and funds provided from operations. The Company utilizes some or all these sources of funds depending on the comparative costs and availability at the time. The Company has from time to time chosen not to pay rates on deposits as high as the rates paid by certain of its competitors and, when believed to be appropriate, supplements deposits with less expensive alternative sources of funds. Since mid-2022, the Company has increased the interest rates it pays on many deposit products. The Company has also utilized both fixed-rate and floating-rate brokered deposits of varying terms, as well as overnight FHLBank borrowings and term borrowings from the FRB.

At June 30, 2024 and December 31, 2023, the Company had the following available secured lines and on-balance sheet liquidity:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | June 30, 2024 |  | December 31, 2023
Federal Home Loan Bank line |  | $ | 1,084.7 million | ​ | $ | 919.1 million
Federal Reserve Bank line | ​ | $ | 339.3 million | ​ | $ | 448.7 million
Cash and cash equivalents | ​ | $ | 186.5 million | ​ | $ | 211.3 million
Unpledged securities – Available-for-sale | ​ | $ | 326.7 million | ​ | $ | 352.8 million
Unpledged securities – Held-to-maturity | ​ | $ | 26.1 million | ​ | $ | 191.7 million

​

Statements of Cash Flows. During the six months ended June 30, 2024 and 2023, the Company had positive cash flows from operating activities. The Company had negative cash flows from investing activities during the six months ended June 30, 2024 and 2023. The Company had positive cash flows from financing activities during the six months ended June 30, 2024 and negative cash flows from financing activities during the six months ended June 30, 2023.

Cash flows from operating activities for the periods covered by the Statements of Cash Flows have been primarily related to changes in accrued and deferred assets, credits and other liabilities, the provision for credit losses, depreciation and amortization, realized gains on sales of loans and the amortization of deferred loan origination fees and discounts (premiums) on loans and investments, all of

​

which are non-cash or non-operating adjustments to operating cash flows. Net income adjusted for non-cash and non-operating items and the origination and sale of loans held for sale were the primary source of cash flows from operating activities. Operating activities provided cash of $16.6 million and $59.0 million during the six months ended June 30, 2024 and 2023, respectively.

During the six months ended June 30, 2024 and 2023, investing activities used cash of $144.2 million and $7.5 million, respectively. Investing activities in the 2024 period used cash primarily due to net originations of loans, purchases of available-for-sale securities and investments in tax credit partnerships, partially offset by the payments received on investment securities. Investing activities in the 2023 period used cash primarily due to net originations of loans, purchases of premises and equipment and investments in tax credit partnerships, partially offset by the payments received on investment securities.

Changes in cash flows from financing activities during the periods covered by the Statements of Cash Flows were due primarily to changes in deposits after interest credited and changes in short-term borrowings, as well as advances from borrowers for taxes and insurance, dividend payments to stockholders and repurchases of the Company’s common stock. During the six months ended June 30, 2024 and 2023, financing activities provided cash of $102.8 million and used cash of $16.1 million, respectively. In the 2024 period, financing activities provided cash primarily as a result of increases in FRB borrowings and short-term borrowings, partially offset by repurchases of the Company’s common stock, dividends paid to stockholders, and net decreases in time deposits and checking and savings deposits. In the 2023 period, financing activities used cash primarily as a result of decreases in short-term borrowings, repurchases of the Company’s common stock and dividends paid to stockholders, partially offset by net increases in time deposits and checking and savings deposits.

Capital Resources

Management continuously reviews the capital position of the Company and the Bank to ensure compliance with minimum regulatory requirements, as well as to explore ways to increase capital either by retained earnings or other means.

At June 30, 2024, the Company’s total stockholders’ equity and common stockholders’ equity were each $568.8 million, or 9.6% of total assets, equivalent to a book value of $49.11 per common share. As of December 31, 2023, total stockholders’ equity and common stockholders’ equity were each $571.8 million, or 9.8% of total assets, equivalent to a book value of $48.44 per common share. At June 30, 2024, the Company’s tangible common equity to tangible assets ratio was 9.4%, compared to 9.7% at December 31, 2023 (See Non-GAAP Financial Measures below).

Included in stockholders’ equity at June 30, 2024 and December 31, 2023, were unrealized losses (net of taxes) on the Company’s available-for-sale investment securities totaling $47.3 million and $40.5 million, respectively. This change in net unrealized losses during the six months ended June 30, 2024, primarily resulted from increasing intermediate-term market interest rates (which generally decreased the fair value of investment securities) during the period.

In addition, included in stockholders’ equity at June 30, 2024, were realized gains (net of taxes) on the Company’s terminated cash flow hedge (interest rate swap), totaling $8.0 million. This amount, plus associated deferred taxes, is expected to be accreted to interest income over the remaining term of the original interest rate swap contract, which was to end in October 2025. At June 30, 2024, the remaining pre-tax amount to be recorded in interest income was $10.3 million. The net effect on total stockholders’ equity over time will be no impact, as the reduction of this realized gain will be offset by an increase in retained earnings (as the interest income flows through pre-tax income).

Also included in stockholders’ equity at June 30, 2024, was an unrealized loss (net of taxes) on the Company’s two outstanding cash flow hedges (interest rate swaps) totaling $16.0 million. Increases in market interest rates since the inception of these hedges have caused their fair values to decrease.

As noted above, total stockholders’ equity decreased $3.0 million, from $571.8 million at December 31, 2023 to $568.8 million at June 30, 2024. Stockholders’ equity decreased due to repurchases of the Company’s common stock totaling $12.4 million and dividends declared on common stock of $9.3 million. Accumulated other comprehensive loss increased $13.0 million during the six months ended June 30, 2024, primarily due to reductions in the fair value of cash flow hedges and available-for-sale investment securities resulting from increases in market interest rates. Partially offsetting these decreases were net income of $30.4 million in the six-month period and a $1.4 million increase in stockholders’ equity due to stock option exercises.

​

The Company also had unrealized losses on its portfolio of held-to-maturity investment securities, which totaled $26.1 million at June 30, 2024, that were not included in its total capital balance. If these held-to-maturity unrealized losses were included in capital (net of taxes) they would have decreased total stockholder’s equity by $19.6 million at June 30, 2024. This amount was equal to 3.5% of total stockholders’ equity of $568.8 million.

Banks are required to maintain minimum risk-based capital ratios. These ratios compare capital, as defined by the risk-based regulations, to assets adjusted for their relative risk as defined by the regulations. Under current guidelines, which became effective January 1, 2015, banks must have a minimum common equity Tier 1 capital ratio of 4.50%, a minimum Tier 1 risk-based capital ratio of 6.00%, a minimum total risk-based capital ratio of 8.00%, and a minimum Tier 1 leverage ratio of 4.00%. To be considered “well capitalized,” banks must have a minimum common equity Tier 1 capital ratio of 6.50%, a minimum Tier 1 risk-based capital ratio of 8.00%, a minimum total risk-based capital ratio of 10.00%, and a minimum Tier 1 leverage ratio of 5.00%. On June 30, 2024, the Bank’s common equity Tier 1 capital ratio was 13.0%, its Tier 1 risk-based capital ratio was 13.0%, its total risk-based capital ratio was 14.2% and its Tier 1 leverage ratio was 11.4%. As a result, as of June 30, 2024, the Bank was well capitalized, with capital ratios in excess of those required to qualify as such. On December 31, 2023, the Bank’s common equity Tier 1 capital ratio was 13.1%, its Tier 1 risk-based capital ratio was 13.1%, its total risk-based capital ratio was 14.3% and its Tier 1 leverage ratio was 11.6%. As a result, as of December 31, 2023, the Bank was well capitalized, with capital ratios in excess of those required to qualify as such.

The FRB has established capital regulations for bank holding companies that generally parallel the capital regulations for banks. On June 30, 2024, the Company’s common equity Tier 1 capital ratio was 12.0%, its Tier 1 risk-based capital ratio was 12.5%, its total risk-based capital ratio was 15.2% and its Tier 1 leverage ratio was 11.0%. On December 31, 2023, the Company’s common equity Tier 1 capital ratio was 11.9%, its Tier 1 risk-based capital ratio was 12.4%, its total risk-based capital ratio was 15.2% and its Tier 1 leverage ratio was 11.0%.

In addition to the minimum common equity Tier 1 capital ratio, Tier 1 risk-based capital ratio and total risk-based capital ratio, the Company and the Bank have to maintain a capital conservation buffer consisting of additional common equity Tier 1 capital greater than 2.5% of risk-weighted assets above the required minimum levels in order to avoid limitations on paying dividends, repurchasing shares, and paying discretionary bonuses. At June 30, 2024 and December 31, 2023, both the Company and the Bank had a capital conservation buffer that exceeded the required minimum levels.

Dividends. During the three months ended June 30, 2024, the Company declared a common stock cash dividend of $0.40 per share, or 28% of net income per diluted common share for that three month period, and paid a common stock cash dividend of $0.40 per share (which was declared in March 2024). During the three months ended June 30, 2023, the Company declared a common stock cash dividend of $0.40 per share, or 26% of net income per diluted common share for that three month period, and paid a common stock cash dividend of $0.40 per share (which was declared in March 2023). During the six months ended June 30, 2024, the Company declared common stock cash dividends totaling $0.80 per share, or 31% of net income per diluted common share for that six month period, and paid common stock cash dividends of $0.80 per share. During the six months ended June 30, 2023, the Company declared common stock cash dividends totaling $0.80 per share, or 25% of net income per diluted common share for that six month period, and paid common stock cash dividends of $0.80 per share. The Board of Directors meets regularly to consider the level and the timing of dividend payments. The $0.40 per share dividend declared but unpaid as of June 30, 2024, was paid to stockholders in July 2024.

Common Stock Repurchases and Issuances. The Company has been in various buy-back programs since May 1990. During the three months ended June 30, 2024, the Company repurchased 124,600 shares of its common stock at an average price of $51.88 per share and issued 7,850 shares of common stock at an average price of $38.77 per share to cover stock option exercises. During the three months ended June 30, 2023, the Company repurchased 170,200 shares of its common stock at an average price of $50.70 per share and issued 5,838 shares of common stock at an average price of $31.07 per share to cover stock option exercises. During the six months ended June 30, 2024, the Company repurchased 236,962 shares of its common stock at an average price of $51.67 per share and issued 15,138 shares of common stock at an average price of $37.15 per share to cover stock option exercises. During the six months ended June 30, 2023, the Company repurchased 269,321 shares of its common stock at an average price of $52.54 per share and issued 7,555 shares of common stock at an average price of $33.79 per share to cover stock option exercises.

In December 2022, the Company’s Board of Directors authorized the purchase of up to one million shares of the Company’s outstanding common stock, under a program of open market purchases or privately negotiated transactions. At June 30, 2024, approximately 490,000 shares remained available in our stock repurchase authorization.

Management has historically utilized stock buy-back programs from time to time as long as management believed that repurchasing the Company’s common stock would contribute to the overall growth of stockholder value. The number of shares that will be repurchased at any particular time and the prices that will be paid are subject to many factors, several of which are outside of the

65

​

control of the Company. The primary factors typically include the number of shares available in the market from sellers at any given time, the market price of the stock and the projected impact on the Company’s earnings per share and capital.

Non-GAAP Financial Measures

This document contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the United States (“GAAP”), specifically, the ratio of tangible common equity to tangible assets.

In calculating the ratio of tangible common equity to tangible assets, we subtract period-end intangible assets from common equity and from total assets. Management believes that the presentation of this measure excluding the impact of intangible assets provides useful supplemental information that is helpful in understanding our financial condition and results of operations, as it provides a method to assess management’s success in utilizing our tangible capital as well as our capital strength. Management also believes that providing a measure that excludes balances of intangible assets, which are subjective components of valuation, facilitates the comparison of our performance with the performance of our peers. In addition, management believes that this is a standard financial measure used in the banking industry to evaluate performance.

This non-GAAP financial measurement is supplemental and is not a substitute for any analysis based on GAAP financial measures. Because not all companies use the same calculation of non-GAAP measures, this presentation may not be comparable to other similarly titled measures as calculated by other companies.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Asset and Liability Management and Market Risk

A principal operating objective of the Company is to produce stable earnings by achieving a favorable interest rate spread that can be sustained during fluctuations in prevailing interest rates. The Company has sought to reduce its exposure to adverse changes in interest rates by attempting to achieve a closer match between the periods in which its interest-bearing liabilities and interest-earning assets can be expected to reprice through the origination of adjustable-rate mortgages and loans with shorter terms to maturity and the purchase of other shorter term interest-earning assets.

Our Risk When Interest Rates Change

The rates of interest we earn on assets and pay on liabilities generally are established contractually for a period of time. Market interest rates change over time. Accordingly, our results of operations, like those of other financial institutions, are impacted by changes in interest rates and the interest rate sensitivity of our assets and liabilities. The risk associated with changes in interest rates and our ability to adapt to these changes is known as interest rate risk and is our most significant market risk.

How We Measure the Risk to Us Associated with Interest Rate Changes

In an attempt to manage our exposure to changes in interest rates and comply with applicable regulations, we monitor Great Southern’s interest rate risk. In monitoring interest rate risk, we regularly analyze and manage assets and liabilities based on their

66

​

payment streams and interest rates, the timing of their maturities and their sensitivity to actual or potential changes in market interest rates.

The ability to maximize net interest income is largely dependent upon the achievement of a positive interest rate spread that can be sustained despite fluctuations in prevailing interest rates. Interest rate sensitivity is a measure of the difference between amounts of interest-earning assets and interest-bearing liabilities which either reprice or mature within a given period of time. The difference, or the interest rate repricing “gap,” provides an indication of the extent to which an institution’s interest rate spread will be affected by changes in interest rates. A gap is considered positive when the amount of interest-rate sensitive assets exceeds the amount of interest-rate sensitive liabilities repricing during the same period, and is considered negative when the amount of interest-rate sensitive liabilities exceeds the amount of interest-rate sensitive assets during the same period. Generally, during a period of rising interest rates, a negative gap within shorter repricing periods would adversely affect net interest income, while a positive gap within shorter repricing periods would result in an increase in net interest income. During a period of falling interest rates, the opposite would be true. As of June 30, 2024, Great Southern’s interest rate risk models indicate that, generally, rising interest rates are expected to have a modestly positive impact on the Company’s net interest income, while declining interest rates are expected to have a modestly negative impact on net interest income. The negative impact of a falling Federal Funds rate and other market interest rates also falling could be more pronounced if we are not able to decrease non-maturity deposit rates accordingly. We model various interest rate scenarios for rising and falling rates, including both parallel and non-parallel shifts in rates. The results of our modeling indicate that net interest income is not likely to be significantly affected either positively or negatively in the first twelve months following relatively minor changes in interest rates because our portfolios are relatively well matched in a twelve-month horizon. In a situation where market interest rates increase significantly in a short period of time, our net interest margin increase may be more pronounced in the very near term (first one to three months), due to fairly rapid increases in SOFR interest rates (which replaced LIBOR interest rates) and “prime” interest rates. In a situation where market interest rates decrease significantly in a short period of time, as they did in March 2020, our net interest margin decrease may be more pronounced in the very near term (first one to three months), due to fairly rapid decreases in SOFR interest rates and “prime” interest rates. In the subsequent months, we would expect that net interest margin would stabilize and begin to improve, as renewal interest rates on maturing time deposits decrease compared to the then-current rates paid on those products. During 2020, we experienced some compression of our net interest margin percentage due to the Federal Funds rate being cut by 2.25% from July 2019 through March 2020. Margin compression primarily resulted from changes in the asset mix, mainly the addition of lower-yielding assets and the issuance of subordinated notes during 2020 and net interest margin remained lower than our historical average in 2021. LIBOR/SOFR interest rates decreased significantly in 2020 and remained very low in 2021 and into the first three months of 2022, putting pressure on loan yields, and strong pricing competition for loans and deposits remained in most of our markets. Since March 2022, market interest rates have increased fairly rapidly. This increased loan yields and expanded our net interest income and net interest margin in the latter half of 2022 and the first three months of 2023. While market interest rate increases are expected to result in increases to loan yields, we expect that much of this benefit will be offset by increased funding costs, including changes in the funding mix, as experienced in the year ended December 31, 2023. As of June 30, 2024, time deposit maturities over the next 12 months were as follows: within three months -- $463 million with a weighted-average rate of 4.46%; within three to six months -- $412 million with a weighted-average rate of 4.47%; and within six to twelve months -- $259 million with a weighted-average rate of 3.98%. Based on time deposit market rates in June 2024, replacement rates for these maturing time deposits are likely to be approximately 4.00-4.35%.

The current level and shape of the interest rate yield curve poses challenges for interest rate risk management. Prior to its increase of 0.25% on December 16, 2015, the FRB had last changed interest rates on December 16, 2008. This was the first rate increase since September 29, 2006. The FRB also implemented rate increases of 0.25% on eight additional occasions beginning December 14, 2016 and through December 31, 2018, with the Federal Funds rate reaching as high as 2.50%. After December 2018, the FRB paused its rate increases and, in July, September and October 2019, implemented rate decreases of 0.25% on each of those occasions. At December 31, 2019, the Federal Funds rate stood at 1.75%. In response to the COVID-19 pandemic, the FRB decreased interest rates on two occasions in March 2020, a 0.50% decrease on March 3rd and a 1.00% decrease on March 16th. At December 31, 2021, the Federal Funds rate was 0.25%. In 2022, the FRB implemented rate increases of 0.25%, 0.50%, 0.75%, 0.75%, 0.75%, 0.75% and 0.50% in March, May, June, July, September, November and December 2022, respectively. At December 31, 2022, the Federal Funds rate was 4.50%. In 2023, the FRB implemented rate increases of 0.25%, 0.25%, 0.25% and 0.25% in February, March, May and July 2023, respectively. At December 31, 2023, the Federal Funds rate was 5.50%. To date in 2024, the FRB has not implemented any rate changes and at June 30, 2024, the Federal Funds rate was 5.50%. Financial markets now expect the possibility of significant further increases in Federal Funds interest rates in 2024 to be unlikely, with interest rate decisions being made at each FRB meeting based on economic data available at the time. However, the FRB has further indicated, and financial markets now have begun to price in, that it is likely that the Federal Funds interest rate will remain near this peak level for a few more months before any rate cuts occur, possibly as early as September 2024. Great Southern’s loan portfolio includes loans ($1.41 billion at June 30, 2024) tied to various SOFR indexes that will be subject to adjustment at least once within 90 days after June 30, 2024. All of these loans have interest rate floors at various rates. Great Southern has a portfolio of loans ($826 million at June 30, 2024) tied to a “prime rate” of interest that will adjust immediately or within 90 days of a change to the “prime rate” of interest. All of these loans had interest rate floors at various rates. In

67

​

addition, Great Southern has a portfolio of loans ($7 million at June 30, 2024) tied to an AMERIBOR index that will adjust immediately or within 90 days of a change to the “prime rate” of interest. All of these loans had interest rate floors at various rates. At June 30, 2024, nearly all of these SOFR, “prime rate” and AMERIBOR loans had fully-indexed rates that were at or above their floor rate and so are expected to move fully with future market interest rate increases.

Interest rate risk exposure estimates (the sensitivity gap) are not exact measures of an institution’s actual interest rate risk. They are only indicators of interest rate risk exposure produced in a simplified modeling environment designed to allow management to gauge the Bank’s sensitivity to changes in interest rates. They do not necessarily indicate the impact of general interest rate movements on the Bank’s net interest income because the repricing of certain categories of assets and liabilities is subject to competitive and other factors beyond the Bank’s control. As a result, certain assets and liabilities indicated as maturing or otherwise repricing within a stated period may in fact mature or reprice at different times and in different amounts and cause a change, which could be material, in the Bank’s interest rate risk.

In order to minimize the potential for adverse effects of material and prolonged increases and decreases in interest rates on Great Southern’s results of operations, Great Southern has adopted asset and liability management policies to better match the maturities and repricing terms of Great Southern’s interest-earning assets and interest-bearing liabilities. Management recommends and the Board of Directors sets the asset and liability policies of Great Southern, which are implemented by the Asset and Liability Committee. The Asset and Liability Committee is chaired by the Chief Financial Officer and is comprised of members of Great Southern’s senior management. The purpose of the Asset and Liability Committee is to communicate, coordinate and control asset/liability management consistent with Great Southern’s business plan and board-approved policies. The Asset and Liability Committee establishes and monitors the volume and mix of assets and funding sources, taking into account relative costs and spreads, interest rate sensitivity and liquidity needs. The objectives are to manage assets and funding sources to produce results that are consistent with liquidity, capital adequacy, growth, risk and profitability goals. The Asset and Liability Committee meets on a monthly basis to review, among other things, economic conditions and interest rate outlook, current and projected liquidity needs and capital positions and anticipated changes in the volume and mix of assets and liabilities. At each meeting, the Asset and Liability Committee recommends appropriate strategy changes based on this review. The Chief Financial Officer or his designee is responsible for reviewing and reporting on the effects of the policy implementations and strategies to the Board of Directors at their monthly meetings.

In order to manage its assets and liabilities and achieve the desired liquidity, credit quality, interest rate risk, profitability and capital targets, Great Southern has focused its strategies on originating adjustable rate loans or loans with fixed rates that mature in less than five years, and managing its deposits and borrowings to establish stable relationships with both retail customers and wholesale funding sources.

At times, depending on the level of general interest rates, the relationship between long- and short-term interest rates, market conditions and competitive factors, we may determine to increase our interest rate risk position somewhat in order to maintain or increase our net interest margin.

The Asset and Liability Committee regularly reviews interest rate risk by forecasting the impact of alternative interest rate environments on net interest income and market value of portfolio equity, which is defined as the net present value of an institution’s existing assets, liabilities and off-balance sheet instruments, and evaluating such impacts against the maximum potential changes in net interest income and market value of portfolio equity that are authorized by the Board of Directors of Great Southern.

In the normal course of business, the Company may use derivative financial instruments (primarily interest rate swaps) from time to time to assist in its interest rate risk management. In 2011, the Company began executing interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. Those interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. Because 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. These interest rate derivatives result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in the Company’s assets or liabilities. The Company manages a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions.

In October 2018, the Company entered into an interest rate swap transaction as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of the swap was $400 million with a contractual termination date of October 6, 2025. Under the terms of the swap, the Company received a fixed rate of interest of 3.018% and paid a floating rate of interest equal to one-month USD-LIBOR (now SOFR). The floating rate reset monthly and net settlements of interest due to/from the counterparty also occurred monthly. Due to lower market interest rates, the Company received net interest settlements which were recorded as loan interest income. If USD-SOFR exceeded the fixed rate of interest, the Company was required to pay net settlements

68

​

to the counterparty and record those net payments as a reduction of interest income on loans. The effective portion of the gain or loss on the derivative was reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affected earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.

In March 2020, the Company and its swap counterparty mutually agreed to terminate the $400 million interest rate swap prior to its contractual maturity. The Company was paid $45.9 million from its swap counterparty as a result of this termination.

In March 2022, the Company entered into another interest rate swap transaction as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of the swap was $300 million with an effective date of March 1, 2022 and a termination date of March 1, 2024. Under the terms of the swap, the Company received a fixed rate of interest of 1.6725% and paid a floating rate of interest equal to one-month USD-LIBOR (now SOFR). The floating rate reset monthly and net settlements of interest due to/from the counterparty also occurred monthly. The initial floating rate of interest was set at 0.24143%. The Company received net interest settlements, which were recorded as loan interest income, to the extent that the fixed rate of interest exceeded one-month USD-SOFR. If the USD-SOFR rate exceeded the fixed rate of interest, the Company paid net settlements to the counterparty and recorded those net payments as a reduction of interest income on loans.

In July 2022, the Company entered into two interest rate swap transactions as part of its ongoing interest rate management strategies to hedge the risk of its floating rate loans. The notional amount of each swap is $200 million with an effective date of May 1, 2023 and a termination date of May 1, 2028. Under the terms of one swap, beginning in May 2023, the Company receives a fixed rate of interest of 2.628% and pays a floating rate of interest equal to one-month USD-SOFR OIS. Under the terms of the other swap, beginning in May 2023, the Company receives a fixed rate of interest of 5.725% and pays a floating rate of interest equal to one-month USD-Prime. In each case, the floating rate resets monthly and net settlements of interest due to/from the counterparty also occur monthly. To the extent the fixed rate of interest exceeds the floating rate of interest, the Company receives net interest settlements, which are recorded as loan interest income. If the floating rate of interest exceeds the fixed rate of interest (as it does currently), the Company pays net settlements to the counterparty and records those net payments as a reduction of interest income on loans.

​

In February 2023, the Company entered into interest rate swap transactions as part of its ongoing interest rate management strategies to hedge the risk of certain of its fixed rate brokered deposits. The total notional amount of the swaps was $95 million with a termination date of February 28, 2025. Under the terms of the swaps, the Company received a fixed rate of interest of 4.65% and paid a floating rate of interest equal to USD-SOFR-COMPOUND plus a spread. The floating rate reset monthly and net settlements of interest due to/from the counterparty also occurred monthly. To the extent that the fixed rate of interest exceeded USD-SOFR-COMPOUND plus the spread, the Company received net interest settlements, which were recorded as a reduction of deposit interest expense. If USD-SOFR-COMPOUND plus the spread exceeded the fixed rate of interest, the Company was required to pay net settlements to the counterparty and record those net payments as interest expense on deposits.

In January 2024, the Company elected to terminate the swaps related to brokered deposits prior to their contractual termination date in 2025. The Company received a net settlement payment from the swap counterparty totaling $26,500 upon termination. At the time of the early termination, the Company recorded a market value adjustment to the brokered deposit of $163,000, which will be amortized as a reduction of interest expense from January 2024 through February 2025.

​

ITEM 4. CONTROLS AND PROCEDURES

We maintain a system of disclosure controls and procedures (as defined in Rule 13 (a)-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”)) that is designed to provide reasonable assurance that information required to be disclosed by us in the reports that we file under the Exchange Act is recorded, processed, summarized and reported accurately and within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate. An evaluation of our disclosure controls and procedures was carried out as of June 30, 2024, under the supervision and with the participation of our principal executive officer, principal financial officer and several other members of our senior management. Our principal executive officer and principal financial officer concluded that, as of June 30, 2024, our disclosure controls and procedures were effective in ensuring that the information we are required to disclose in the reports we file or submit under the Exchange Act is (i) accumulated and communicated to our management (including the principal executive officer and principal financial officer) to allow timely decisions regarding required disclosure, and (ii) recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

There were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended June 30, 2024, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

69

​

We do not expect that our internal control over financial reporting will prevent all errors and all fraud. A control procedure, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control procedure are met. Because of the inherent limitations in all control procedures, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns in controls or procedures can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the control. The design of any control procedure also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control procedure, misstatements due to error or fraud may occur and not be detected.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

In the normal course of business, the Company and its subsidiaries are subject to pending and threatened legal actions, some of which seek substantial relief or damages. While the ultimate outcome of such legal proceedings cannot be predicted with certainty, after reviewing pending and threatened litigation with counsel, management believes at this time that the outcome of such litigation will not have a material adverse effect on the Company’s business, financial condition or results of operations. For additional information, see Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Business Initiatives” in this report.

Item 1A. Risk Factors
