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 months ended March 31, 2023 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, 2022, 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, 2022 filed with the Securities and Exchange Commission (the “SEC”).

​

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; Phoenix; and Tulsa, Oklahoma. 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 also 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

6

​

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 March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging (Topic 815): Fair Value Hedging – Portfolio Layer Method. ASU 2022-01 further clarifies certain targeted improvements to the optional hedge accounting model that were made under ASU 2017-12. ASU 2022-01 expands the last-of-layer method and renames this method to portfolio layer method to reflect this expansion, as well as expanding the scope of the portfolio layer method to include nonprepayable financial assets. It also specifies eligible hedging instruments and provides additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method. ASU 2022-01 permits an entity to apply the same portfolio hedging method to both prepayable and nonprepayable financial assets, thereby allowing consistent accounting for similar hedges. ASU 2022-01 is effective for the Company on January 1, 2023. The adoption of ASU 2022-01 did not have a material impact on the Company’s consolidated financial statements.

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 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 existing disclosure requirements and introduces new requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. ASU 2022-02 is effective for the Company on January 1, 2023. The adoption of ASU 2022-02 did not have a material impact on the Company’s consolidated financial statements. The adoption of this ASU does, however, require changes in disclosures related to certain loan modifications.

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.

​

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.

7

​

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 March 31, 2023 and December 31, 2022, was approximately $467.7 million and $472.0 million, respectively, which is approximately 94.8% and 96.2% of the Company’s total available-for-sale investment portfolio. A high percentage of the unrealized losses were related to the Company’s mortgage-backed securities, collateralized mortgage obligations and 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 cost at March 31, 2023 and December 31, 2022, which was $200.4 million and $202.5 million, respectively. Total fair value of these investments at March 31, 2023 and December 31, 2022 was approximately $179.9 million and $177.8 million, respectively. Held-to-maturity investment securities are evaluated for potential losses under ASU 2016-13. The Company continually assesses its liquidity sources, both on-balance sheet and off-balance sheet, and believes at March 31, 2023, that it has ample liquidity sources to fund its ongoing operations. The Company has the intent and ability to hold these held-to-maturity securities until they are fully repaid.

Based on an evaluation of available evidence, including recent changes in market interest rates, credit rating information and information obtained from regulatory filings, management believes any declines in fair value for these debt securities are temporary.

The following table shows the Company’s available-for-sale and held-to-maturity securities’ gross unrealized losses and fair value, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at March 31, 2023 and December 31, 2022:

There were no sales of available-for-sale securities during the three months ended March 31, 2023. Available-for-sale securities totaling $4.9 million were sold during the three months ended March 31, 2022, resulting in the recognition of a $7,000 gain during the period. Gains and losses on sales of securities are determined on the specific-identification method.

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 are 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 experienced historical 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 highly rated by major rating agencies and have a long history of no credit losses. Likewise, the Company historically has not 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 Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, effective January 1, 2021. 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, 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 amortized cost of loans 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.

ASU 2016-13 requires an allowance for off balance sheet credit exposures: unfunded lines of credit, undisbursed portions of loans, written residential and commercial 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.

Classes of loans at March 31, 2023 and December 31, 2022 were as follows:

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 these loans for the three months ended March 31, 2023 and 2022, respectively.

Nonaccrual loans for which there is no related allowance for credit losses as of March 31, 2023 had an amortized cost of $1.7 million. 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.

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 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 existing disclosure requirements and introduces new disclosure requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. ASU 2022-02 was effective for the Company on January 1, 2023.

Adoption of this amendment 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 troubled debt restructuring (“TDR”) disclosures, replaced by additional disclosures on the types of modifications of loans to borrowers experiencing financial difficulties. The Corporation has adopted this update prospectively.

Under ASU 2022-02, effective January 1, 2023, loan modifications are reported if concessions have been granted to borrowers that are experiencing financial difficulty. Information on these loan modifications originated after the effective date is presented according to the new accounting guidance. Reporting periods prior to the adoption of ASU 2022-02 present information on TDRs under the previous disclosure requirements.

The following tables show the composition of loan modifications made to borrowers experiencing financial difficulty by the loan portfolio and type of concessions granted during the three months ended March 31, 2023. Each of the types of concessions granted comprised less than 2.5% of their respective classes of loan portfolios at March 31, 2023.

At December 31, 2022, of the $2.9 million in TDRs, $1.7 million were classified as substandard using the Company’s internal grading system. The Company had no TDRs that were modified in the previous 12 months and subsequently defaulted during the year ended December 31, 2022.

During the three months ended March 31, 2022, $221,000 of loans met the criteria for placement back on accrual status. The criteria was generally a minimum of six months of consistent and timely payment performance under original or modified terms.

The nature and extent of impairments of modified loans, including those which have experienced a subsequent payment default, are considered in the determination of an appropriate level of the allowance for credit losses. 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 information, including but not limited to current financial information, historical payment experience, industry information, collateral levels and collateral 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 strong, 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 and 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. It is a transitional grade that is 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. Loans considered loss are 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 quarterly review and 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.

​

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

20

​

corresponding lease liability will fluctuate based on the Company’s lease terminations, new leases and lease modifications and renewals. As of March 31, 2023, the lease right of use asset value was $7.5 million and the corresponding lease liability was $7.7 million. As of December 31, 2022, the lease right of use asset value was $7.4 million and the corresponding lease liability was $7.6 million. At March 31, 2023, expected lease terms ranged from 1.1 years to 15.7 years with a weighted-average lease term of 7.4 years. The weighted-average discount rate at March 31, 2023 was 3.75%.

For the three months ended March 31, 2023 and 2022, lease expense was $411,000 and $369,000, 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 and the total lease expense related to ATMs for the three months ended March 31, 2023 and 2022 was $72,000 and $69,000, 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 March 31, 2023 and 2022, income recognized from these lease agreements was $324,000 and $294,000, respectively, and was included in occupancy and equipment expense.

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 March 31, 2023 and 2022, totaled $75,000 and $74,000, 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 5.95%.

At March 31, 2023 and December 31, 2022, subordinated notes are summarized as follows:

NOTE 14: INCOME TAXES

Reconciliations of the Company’s effective tax rates to the statutory corporate tax rates were as follows:

​

​ |  | 21.2 | % | 20.5 | %

​

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, 2018 are now closed.

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 has engaged legal and tax advisors and continues to believe it will ultimately prevail on the issue; however, if the Company does not prevail, the tax obligation to the State of Missouri could be up to a total of $4.0 million for these tax years and additional amounts could be levied for subsequent tax years. The MAHC has received documents from each party but no hearings have occurred to date.

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 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.

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 March 31, 2023 and December 31, 2022:

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 March 31, 2023 and December 31, 2022 as well as the general classification of such assets pursuant to the valuation hierarchy. There have been no significant changes in the valuation techniques during the three-month period ended March 31, 2023. 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, LIBOR/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 values derived from the independent pricing service’s proprietary computerized models. There were no recurring Level 3 securities at March 31, 2023 or December 31, 2022.

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 fair value measurements of assets measured at fair value on a nonrecurring basis and the level within the hierarchy in which such measurements fell at March 31, 2023 and December 31, 2022:

​

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 March 31, 2023 and December 31, 2022, 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.

25

​

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 during the three months ended March 31, 2023 or the year ended December 31, 2022, are shown in the table above (net of reserves).

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. The foreclosed assets represented in the table above have been re-measured during the three months ended March 31, 2023 or the year ended December 31, 2022, subsequent to their initial transfer to foreclosed 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 techniques, that consider observable market data, such as interest rate volatilities, LIBOR/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, prepayments, discount spreads, credit losses and liquidity premiums. Loans with similar characteristics were 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 through 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 on the statements of financial condition. 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 are designated in a qualified hedging relationship.

Nondesignated Hedges

The Company has interest rate swaps that are not designated as qualifying hedging relationships. Derivatives not designated as hedges are not speculative and result from a service the Company provides to certain loan customers, which the Company began offering during 2011. 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.

27

​

At March 31, 2023, the Company had seven interest rate swaps and one interest rate cap totaling $111.1 million in notional amount with commercial customers, and seven interest rate swaps and one interest rate cap with the same aggregate notional amount with third parties related to its program. In addition, the Company has one participation loan purchased totaling $8.8 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, 2022, the Company had six interest rate swaps and one interest rate cap totaling $107.0 million in notional amount with commercial customers, and six interest rate swaps and one interest rate cap with the same notional amount with third parties related to its program. In addition, at December 31, 2022, the Company had one participation loan purchased totaling $8.8 million, in which the lead institution has an interest rate swap with their customer and the economics of the counterparty swap are passed along to the Company through the loan participation. During the three months ended March 31, 2023 and 2022, the Company recognized net losses of $291,000 and net gains of $152,000, 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 receives a fixed rate of interest of 4.65% and pays a floating rate of interest equal to USD-SOFR-COMPOUND plus a spread. The floating rate resets monthly and net settlements of interest due to/from the counterparty also occurs monthly. To the extent that the fixed rate of interest exceeds USD-SOFR-COMPOUND plus the spread, the Company receives net interest settlements which are recorded as a reduction of deposit interest expense. If USD-SOFR-COMPOUND plus the spread exceeds the fixed rate of interest, the Company is required to pay net settlements to the counterparty and record those net payments as interest expense on deposits.

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, is reflected in the Company’s stockholders’ equity as Accumulated Other Comprehensive Income and a portion of it will be 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 March 31, 2023, 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.

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 is $300 million, with a termination date of March 1, 2024. Under the terms of the swap, the Company receives a fixed rate of interest of 1.6725% and pays a floating rate of interest equal to one-month USD-LIBOR (or the equivalent replacement rate if USD-LIBOR rate is not available). The floating rate resets monthly and net settlements of interest due to/from the counterparty also occur monthly. The floating rate of interest was 4.66943% as of March 31, 2023. To the extend the floating rate of interest exceeds the fixed rate of interest, the Company will be required to pay net settlements to the counterparty and will record those net payments as a reduction of interest income on loans. If the fixed rate of interest exceeds the floating rate of interest, the Company will receive net interest settlements, which will be recorded as loan interest income. On April 1, 2023, the floating rate of interest reset to 4.85771%.

28

​

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, beginning in May 2023, the Company will receive a fixed rate of interest of 2.628% and will pay 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 will receive a fixed rate of interest of 5.725% and will pay a floating rate of interest equal to one-month USD-Prime. In each case, the floating rate will be reset monthly and net settlements of interest due to/from the counterparty will also occur monthly. To the extent the fixed rate of interest exceeds the floating rate of interest, the Company will receive net interest settlements, which will be recorded as loan interest income. If the floating rate of interest exceeds the fixed rate of interest, the Company will be required to pay net settlements to the counterparty and will record those net payments as a reduction of interest income on loans. At March 31, 2023, the USD-Prime rate was 8.00% and the one-month USD-SOFR OIS rate was 4.62101%.

The Company recorded loan interest income of $2.0 million on the terminated interest rate swap during each of the three months ended March 31, 2023 and 2022. The Company recorded negative loan interest income of $2.2 million and loan interest income of $370,000, related to the March 2022 interest rate swap during the three months ended March 31, 2023 and March 31, 2022, respectively. 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-months ended March 31, 2023 and 2022, the Company recognized no non-interest income related to changes in the fair value of these derivatives. At March 31, 2023, the Company expected to have an 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.

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 March 31, 2023, the termination value of derivatives with our derivative dealer counterparties (related to loan level swaps with commercial lending customers and an active interest rate swap 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 $183,000. The Company has minimum collateral posting thresholds with its derivative dealer counterparties. At March 31, 2023, the Company had given cash collateral to one derivative counterparty of $14.6 million to cover its net fair value position. This counterparty position included collateral from the counterparty of $9.0 million for commercial lending swaps, collateral from the counterparty of $894,000 for swaps related to brokered deposits and collateral from the Company of $23.3 million for interest rate swaps related to variable rate loans.

At December 31, 2022, the termination value of derivatives with our derivative dealer counterparties (related to loan level swaps with commercial lending customers) in a net asset position, which included accrued interest but excluded any adjustment for nonperformance risk, related to these agreements was $242,000. Additionally, the Company’s activity with one of its derivative counterparties met the level at which the minimum collateral posting thresholds take effect (collateral to be given by the Company) and the Company had posted collateral of $20.7 million to the derivative counterparty.

If the Company had breached any of these provisions at March 31, 2023 or December 31, 2022, 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 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, and labor shortages 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, including on our credit quality and business operations, as well as its impact on general economic and financial market conditions and other uncertainties resulting from the COVID-19 pandemic; (iv) fluctuations in interest rates and the effects of inflation, a potential recession or slower economic growth caused by changes in energy prices or supply chain disruptions; (v) 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; (vi) the possibility of realized or unrealized losses on securities held in the Company’s investment portfolio; (vii) the Company’s ability to access cost-effective funding and maintain sufficient liquidity; (viii) fluctuations in real estate values and both residential and commercial real estate market conditions; (ix) the ability to adapt successfully to technological changes to meet customers’ needs and developments in the marketplace; (x) 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; (xi) legislative or regulatory changes that adversely affect the Company’s business; (xii) changes in accounting policies and practices or accounting standards; (xiii) 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; (xiv) costs and effects of litigation, including settlements and judgments; (xv) competition; (xvi) uncertainty regarding the future of LIBOR and potential replacement indexes; and (xvii) 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 from time to time in documents filed or furnished by the Company with the SEC could affect the Company’s financial performance and could 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 of America 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

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, disposable income and market volatility. 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 back to historical averages using a straight-line method. The forecast adjusted loss rate is applied to the amortized cost of loans 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 forecast such as changes in portfolio composition, underwriting practices, or significant unique events or conditions.

See Note 6 “Loans and Allowance for Credit Losses” of the accompanying financial statements for additional information regarding the allowance for credit losses. Inherent in this process is the evaluation of individual significant credit relationships. From time to time certain credit relationships may deteriorate due to payment performance, cash flow of the borrower, value of collateral, or other factors. In these instances, management may revise its loss estimates and assumptions for these specific credits due to changing circumstances. In some cases, additional 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.

On January 1, 2021, the Company adopted the new accounting standard related to the allowance for credit losses. For assets held at amortized cost basis, 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 of the accompanying financial statements for additional information.

In addition, the Company considers that the determination of the valuations 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 sales 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 sales of the assets could differ materially from the carrying value reflected in the financial statements, resulting in losses that could adversely 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 March 31, 2023, 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, if any. 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 March 31, 2023, 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 in the St. Louis market from Fifth Third Bank. 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 March 31, 2023, the amortizable intangible assets included the arena naming rights of $5.3 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 March 31, 2023. While management believes no impairment existed at March 31, 2023, 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 is as follows:

​ | ​ | March 31, | ​ | December 31,

Current Economic Conditions

Changes in economic conditions could cause the values of assets and liabilities recorded in the financial statements to change rapidly, resulting in material future adjustments in 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. The pandemic has not been disruptive to the U.S. and global economies for several months now, with governments, households and businesses increasingly adept at making adjustments for the virus.

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. Hunkered down at home 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 that would 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 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 that 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 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 Reserve continues to aggressively tighten monetary policy by increasing rates and allowing its balance sheet to shrink through quantitative tightening. The federal government deficit was $2.8 trillion in fiscal 2021, close to $1.38 trillion in fiscal 2022, and is expected to be $1.4 trillion in fiscal 2023. The publicly traded debt-to-GDP ratio is near 95%, up from 80% prior to the pandemic and 35% prior to the global financial crisis. Lawmakers were appropriately not focused on deficits during the pandemic, but as the pandemic fades, addressing the fragile fiscal situation becomes critical. Real gross domestic product (GDP) increased at an annual rate of 2.9% in the fourth quarter of 2022 according to the “advance” estimate released by the Bureau of Economic Analysis. In the third quarter of 2022, real GDP increased 3.2%. The fourth quarter 2022 increase primarily reflected increases in inventory investment and consumer spending that were partly offset by a decrease in housing investment.

Prompting the Fed to take such a hawkish policy stance is the painfully high inflation, resulting largely from pandemic-related disruptions to global supply chains and labor markets, and Russia’s invasion of Ukraine, which pushed up oil and other commodity prices. Adding to the pressure to act is the resilient growth in jobs, low unemployment in the mid-3s (consistent with full employment), and overly strong wage growth. The unemployment rate returned to its post-pandemic low of 3.5%, and it did so even as the labor force expanded by 439,000 and the participation rate edged higher to 62.3%. The unemployment rate was down or unchanged across most major demographic groups. However, the least educated workers saw an increase in joblessness from 4.4% to 5%. The Fed increased the fed funds rate by 50 basis points at the December 2022 meeting of the Federal Open Market Committee and 25 basis points in each of February 2023 and March 2023. This brings the funds rate target to 5.00%. The Fed also continues to allow the assets on its balance sheet, including more than $8.3 trillion remaining in Treasury and mortgage-backed securities, to mature and prepay.

The Inflation Reduction Act was enacted in August 2022, which raises nearly $750 billion over the next decade through higher taxes on large corporations and wealthy individuals and lower Medicare prescription drug costs, to pay for nearly $450 billion in tax credits and deductions and additional government spending to address climate change and lower health insurance premiums for Americans who benefit from the Affordable Care Act. The remaining more than $300 billion goes to reducing future budget deficits.

In April 2023, global oil prices hovered near $80 per barrel. This reflects the graceful implementation of the European Union’s sanctions on Russian oil and a price cap on Russian oil imposed by Western nations led by the U.S. Chinese oil demand has picked up with its economy, but there has been enough supply, at least so far. The estimated long-run equilibrium price of oil is near $70 per barrel.

Ten-year Treasury yields have fallen back to near 3.5% given the angst created by recent bank failures and global investors’ flight to quality. Yields are consistent with Moody’s Analytics’ estimate of nominal potential GDP growth of 4% (2% long-run inflation plus 2% real potential GDP growth). Moody’s expects yields to hover near 4% for the foreseeable future.

Employment

The national unemployment rate remained unchanged at 3.5% in March 2023. The number of unemployed individuals increased slightly to 5.8 million in March 2023. Both measures have shown little net movement since early 2022. Total employment increased by 236,000 in March 2023, compared with the average monthly gain of 334,000 over the prior 6 months. In March 2023, employment continued to trend up in leisure and hospitality, government, professional and business services, and health care. Unemployment levels have recovered to pre-pandemic levels as of February 2020 when the unemployment rate registered at 3.5% and there were 5.8 million unemployed individuals.

Job cuts occurred in technology, warehousing and storage, building material, garden equipment, supplies dealers, furniture, home furnishings, electronics, and appliance retailers.

As of March 2023, the labor force participation rate (the share of working-age Americans employed or actively looking for a job) remained little changed at 62.6%. Based on March 2023 information, the unemployment rate for the Midwest, where the Company conducts most of its business, has decreased from 3.6% in March 2022 to 3.4% in March 2023. Unemployment rates for March 2023 in the states where the Company has a branch or a loan production office were Arizona at 3.5%, Arkansas at 3.0%, Colorado at 2.8%, Georgia at 3.1%, Illinois at 4.4%, Iowa at 2.8%, Kansas at 2.9%, Minnesota at 2.8%, Missouri at 2.5%, Nebraska at 2.1%, North Carolina at 3.5%, Oklahoma at 3.0%, and Texas at 4.0%. Of the metropolitan areas in which the Company does business, most are below the national unemployment rate of 3.5% for March 2023, with the major outlier being Chicago at 4.4%.

Single Family Housing

Sales of new single-family houses in March 2023 were at a seasonally adjusted annual rate of 683,000, according to the estimates released jointly by the U.S. Census Bureau and Department of Housing and Urban Development. This is 9.6% above the revised February 2023 rate of 623,000 but is 3.4% below the March 2022 estimate of 707,000.

The median sales price of new houses sold in March 2023 was $449,800, up from $435,900 in March 2022. The average sales price in March 2023 of $511,800 was up from $540,000 in March 2022. The seasonally‐adjusted estimate of new houses for sale at the end of March was 432,000. This represents a supply of 7.6 months at the current sales rate.

National existing-home sales fell 2.4% in March 2023 to a seasonally adjusted annual rate of 4.44 million. Year-over-year, sales waned 22.0% (down from 5.69 million in March 2022). Existing–home sales in the Midwest retracted 5.5% from Febraury 2023 to an annual rate of 1.03 million in March 2023, falling 17.6% from the previous year.

The median existing-home sales price nationally as of March 2023 was $375,700, a decline of 0.9% from March 2022 ($379,300). The median price in the Midwest was $273,400, up 1.7% from March 2022.

Nationally, properties on average remained on the market for 29 days in March 2023, down from 34 days in February 2023 but up from 17 days in March 2022. Sixty-five percent of homes sold in March 2023 were on the market for less than a month.

Unsold inventory sits at a 2.6-month supply at the current sales pace for March 2023, unchanged from February 2023 but up from 2.0 months in March 2022.

Once overall consumer price inflation calms and rents decelerate from robust apartment construction, the Federal Reserve’s monetary policy may shift from tightening to neutral to possibly loosening over the next 12 months.

First-time homebuyers accounted for 28% of sales in March 2023, up from 27% in February 2023 but down from 30% in March 2022.

According to Freddie Mac, the average commitment rate for a 30-year, fixed-rate mortgage was 6.27% as of April 13, 2023 which is down from 6.28% from the prior week but up from 5% one year ago.

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

The multi-family trend of supply outpacing demand continued for the sixth quarter in a row to start off 2023. Net absorption rebounded into positive territory after turning negative at the end of 2022, with 42,000 units absorbed. However, with 109,000 new units delivered during the first quarter of 2023, rent growth nationally decelerated once again, going from 3.8% at the end of 2022 to 2.2% at March 2023.

Midwest and Northeast markets fared the best over the past 12 months, with rent growth down marginally. Sun Belt markets have seen significant pull back in rents over the past 12 months. Phoenix has gone from rent growth rates of 17% to -1.9%. The downward movement of rents nationally is expected to continue for the rest of 2023, as the risk of recession hangs over the economy and many markets are experiencing oversupply conditions.

The supply/demand imbalance has pushed the national vacancy rate up 200 basis points from an all-time low of 4.7% in the third quarter of 2021 to 6.7% as of March 31, 2023. CoStar’s current forecast is for the national vacancy rate to finish this year in the mid 7% range, which would be 100 basis points higher than pre-pandemic levels. As indicated above, absorption in the first quarter of 2023 registered just 42,000 units, which is well below the five-year pre-pandemic average of 82,000. Tempering of multi-family demand has come from higher costs due to elevated inflation. Significant rent increases in 2021 and 2022 also are forcing some renter households to find alternative housing situations, such as returning home to their parents or finding a roommate. Plus, economic uncertainty continues to hold back household formation, which is dampening middle market demand.

When demand in the multi-family market spiked in the first year of the pandemic, developers accelerated plans for new projects. Now two years later, a good number of those developments are set to deliver in 2023. The national forecast sits at 519,000 new units to be delivered in 2023, the most new supply to hit the market since the mid-1980s.

The rising interest rate environment, combined with a pullback in construction lending, has led some developers nationwide to not move forward on proposed projects. With fewer projects moving forward, there could be a meaningful pause in deliveries towards the

35

​

end of 2024 and into 2025. This pause would be very helpful in allowing many overbuilt Sun Belt markets to soak up the current supply overhang and return to equilibrium quicker.

Multi-family continued to be the most sought-after asset type in 2022 despite a pullback in transaction activity. On the heels of a record-breaking 2021, sales decreased to $227 billion, representing the second-best year on record. However, this activity occurred primarily in the first half of 2022 with the second half of 2022 weakening, posting a 25% decline over the prior six months.

As of March 31, 2023, national multi-family market vacancy rates increased to 6.7%. Our market areas reflected the following apartment vacancy levels as of March 2023: Springfield, Missouri at 3.7%, St. Louis at 8.9%, Kansas City at 7.8%, Minneapolis at 7.3%, Tulsa, Oklahoma at 8.2%, Dallas-Fort Worth at 8.7 %, Chicago at 5.6%, Atlanta at 9.6%, Phoenix at 9.1%, Denver at 7.4% and Charlotte, North Carolina at 9.4%.

Demand for office market space continues its decline. Tenants gave back another 20 million square feet during the first quarter, bringing total net absorption since the end of 2019 to a staggering -140 million square feet. This propelled vacancy to a record 12.9%, eclipsing its peak from the Great Recession. There is every indication that vacancies will continue to rise, especially with 60 million square feet of new supply—the most in a calendar year since 2009—projected to come online by the end of 2023.

As of March 31, 2023, national office vacancy rates increased to 12.8% from 12.7% as of December 31, 2022, while our market areas reflected the following vacancy levels at March 31, 2023: Springfield, Missouri at 4.2%, St. Louis at 10.2%, Kansas City at 11.6%, Minneapolis at 11.0%, Tulsa, Oklahoma at 11.8%, Dallas-Fort Worth at 18.0%, Chicago at 15.4%, Atlanta at 14.1%, Denver at 14.8%, Phoenix at 15.2% and Charlotte, North Carolina at 12.6%.

U.S. retail tenants signed for over 230 million square feet (SF) of retail space in 2022, which was the second-highest total for any year since 2017. At the same time, tenants closed just 20 million SF of retail space during 2022, which was the lowest total recorded since before the Great Recession and a fraction of the prior five-year average for retail space closed of 114.6 million SF. The combination of strong leasing volumes and the significant reduction in move-outs drove net absorption to its highest level in six years in 2022, at 74 million SF.

Fundamental tightening and rising retail sales pushed retail asking rents upward at their fastest clip in over a decade in 2022 at 4.1%, with average triple net asking rents across the U.S. finishing the year at a record high of $24.00/SF. However, growth has slowed in each of the past two quarters and is forecast to decelerate further over the coming quarters, while above-average inflation is expected to continue to weigh on the real rate of rent growth, keeping it below historical norms for the foreseeable future.

During the first quarter of 2023, national retail vacancy rates remained steady at 4.2% while our market areas reflected the following vacancy levels: Springfield, Missouri at 3.4%, St. Louis at 5.0%, Kansas City at 4.2%, Minneapolis at 3.1%, Tulsa, Oklahoma at 3.0%, Dallas-Fort Worth at 4.6%, Chicago at 5.4%, Atlanta at 3.7%, Phoenix at 5.0%, Denver at 4.1%, and Charlotte, North Carolina at 3.2%.

U.S. industrial market performance is slowing down heading into mid-2023. While the national vacancy rate is expected to remain below its 20-year average of 7.3%, the next six to 12 months could still prove to be one of the more challenging periods for the market over the next five years.

Oncoming new supply is all but certain to push the national vacancy rate up during 2023. CoStar is tracking 619 million SF of projects under construction, most of which are unleased and set to be completed in 2023. The national vacancy rate has already begun to inch up in recent quarters and rent growth is slowing from the peak of 3% quarterly growth reached in mid-2022. Further deceleration in rent growth seems unavoidable in 2023, given that landlords will be contending with a record amount of speculative development, at a time when 2022’s sharp interest rate increases will likely still be weighing on the macro economy.

At March 31, 2023, national industrial vacancy rates increased to 4.5% from 4.2% as of December 31, 2022. Our market areas reflected the following vacancy levels: Springfield, Missouri at 1.2%, St. Louis at 4.4%, Kansas City at 3.8%, Minneapolis at 2.9%, Tulsa, Oklahoma at 4.0%, Dallas-Fort Worth at 6.4%, Chicago at 4.0%, Atlanta at 4.3%, Phoenix at 4.1%, Denver at 6.7% and Charlotte, North Carolina at 4.8%.

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.

COVID-19 Impact to Our Business and Response

Great Southern continues to monitor and respond to the effects of the COVID-19 pandemic. As always, the health, safety and well-being of our customers, associates and communities, while maintaining uninterrupted service, are the Company’s top priorities. Centers for Disease Control and Prevention (CDC) guidelines, as well as directives from federal, state and local officials, are being closely followed to make informed operational decisions, if necessary.

Customers can conduct their banking business using our banking center network, online and mobile banking services, ATMs, Telephone Banking, and online account opening services.

COVID-19 infection rates currently are relatively low in our markets and the CDC has relaxed most restrictions that were previously in place. In some cases those restrictions have been replaced with recommendations. Also, states and local municipalities may restrict certain activities from time to time. Our business is currently operating normally, similar to operations prior to the onset of the COVID-19 pandemic. We continue to monitor infection rates and other health and economic indicators to ensure we are prepared to respond to future challenges, should they arise.

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 $88.0 million, or 1.5%, from $5.68 billion at December 31, 2022, to $5.77 billion at March 31, 2023. Details of the current period changes in total assets are provided below, under “Comparison of Financial Condition at March 31, 2023 and December 31, 2022.”

Loans. Net outstanding loans increased $62.5 million, or 1.4%, from $4.51 billion at December 31, 2022, to $4.57 billion at March 31, 2023. The increase was primarily in other residential (multi-family) loans and commercial real estate loans. These increases were partially offset by a decrease in construction 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), commercial real estate and one- to four family residential real estate, 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, Phoenix and Tulsa. Certain minimum underwriting standards and monitoring 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 also subject to certain minimum underwriting standards to assure portfolio quality. In 2019, the Company discontinued indirect auto loan originations.

37

​

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 March 31, 2023 and December 31, 2022, 0.2% of our owner occupied one-to four-family residential loans had loan-to-value ratios above 100% at origination and an estimated 0.2% of total 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 performance on the loans. Generally, the higher the level of non-performing assets, the greater the negative impact on interest income and net income.

The Company continues its preparation for discontinuation of use of interest rates such as LIBOR. LIBOR is a benchmark interest rate referenced in a variety of agreements used by the Company, but by far the most significant area impacted by LIBOR is related to commercial and residential mortgage loans. Certain LIBOR rates are no longer published and it is expected that all LIBOR rates will be discontinued as reference rates by June 30, 2023. Other interest rates used globally could be discontinued for similar reasons.

The Company has been regularly monitoring its portfolio of loans tied to LIBOR since 2019, with specific groups of loans identified. The Company implemented LIBOR fallback language for all commercial loan transactions near the end of 2018, with such language utilized for all commercial loan originations and renewals/modifications since that time. The Company is monitoring the remaining group of loans that were originated prior to the fourth quarter of 2018, and have not been renewed or modified since that time. At March 31, 2023, this represented approximately 23 commercial loans totaling approximately $21 million; however, only 14 of those loans, totaling $860 thousand, mature after June 2023 (the date upon which the LIBOR indices used by the Company are expected to no longer be available). The Company also has a portfolio of residential mortgage loans tied to LIBOR indices with standard index replacement language included (approximately $351 million at March 31, 2023), and that portfolio is being monitored for potential changes that may be facilitated by the mortgage industry. The vast majority of the loan portfolio tied to LIBOR now includes LIBOR replacement language that identifies “trigger” events for the cessation of LIBOR and the steps that the Company will take upon the occurrence of one or more of those events, including adjustments to any rate margin to ensure that the replacement interest rate on the loan is substantially similar to the previous LIBOR-based rate.

Available-for-sale Securities. In the three months ended March 31, 2023, available-for-sale securities increased $2.7 million, or 0.6%, from $490.6 million at December 31, 2022, to $493.3 million at March 31, 2023.

Held-to-maturity Securities. In the three months ended March 31, 2023, held-to-maturity securities decreased $2.1 million, or 1.0%, from $202.5 million at December 31, 2022, to $200.4 million at March 31, 2023.

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 three months ended March 31, 2023, total deposit balances increased $114.2 million, or 2.4%. Compared to December 31, 2022, transaction account balances decreased $26.3 million, or 0.8%, to $3.23 billion at March 31, 2023, while retail certificates of deposit increased $14.9 million, or 1.5%, to $1.04 billion at March 31, 2023. 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 increased due to an increase in retail certificates generated through the banking center network, partially offset by decreases in national time deposits initiated through internet channels. Time deposits initiated through internet channels are no longer a significant part of the Company’s total deposits. Brokered deposits, including IntraFi program purchased funds, were $537.0 million and $411.5 million at March 31, 2023 and December 31, 2022, 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 obtain 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 Months Ended March 31, 2023 and 2022 – Liquidity” below for further information on funding sources.

Securities sold under reverse repurchase agreements with customers. Securities sold under reverse repurchase agreements with customers decreased $106.1 million from $176.8 million at December 31, 2022 to $70.7 million at March 31, 2023. These balances fluctuate over time based on customer demand for this product.

Short-term borrowings and other interest-bearing liabilities. The Company’s FHLBank term advances were $-0- at both March 31, 2023 and December 31, 2022. At March 31, 2023 there were $154.5 million in overnight borrowings from the FHLBank, which are included in short term borrowings. At December 31, 2022 there were $88.5 million in overnight borrowings from the FHLBank.

Short term borrowings and other interest-bearing liabilities increased $66.1 million from $89.6 million at December 31, 2022 to $155.7 million at March 31, 2023. The Company may utilize both overnight borrowings and short-term FHLBank advances depending on relative interest rates.

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 LIBOR/SOFR, three-month LIBOR 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 “Item 3. 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 3 and a 1.00% decrease on March 16. 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% and 0.25% in February and March 2023, respectively. At March 31, 2023 the Federal Funds rate was 5.00%. Financial markets expect the possibility of further increases in Federal Funds interest rates in the first half of 2023, with 0.25-0.50% of additional cumulative rate hikes currently anticipated. A substantial portion of Great Southern’s loan portfolio ($868.8 million at March 31, 2023) is tied to the one-month or three-month LIBOR index and will be subject to adjustment at least once within 90 days after March 31, 2023. Of these loans, $868.5 million had interest rate floors. Great Southern’s loan portfolio also includes loans ($693.4 million at March 31, 2023) tied to various SOFR indexes that will be subject to adjustment at least once within 90 days after March 31, 2023. Of these loans, $693.4 million had interest rate floors. Great Southern also has a portfolio of loans ($738.6 million at March 31, 2023) tied to a “prime rate” of interest that will adjust immediately or within 90 days of a change to the “prime rate” of interest. Of these loans, $725.8 million had interest rate floors at various rates. Great Southern also has a portfolio of loans ($6.7 million at March 31, 2023) tied to an AMERIBOR index that will adjust immediately or within 90 days of a change to the “prime rate” of interest. Of these loans, $6.7 million had interest rate floors at various rates. At March 31, 2023, nearly all of these LIBOR/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 one-month or three-month LIBOR index, SOFR indices 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, although interest rates on assets may decline further. Conversely, market interest rate increases would normally result in increased interest rates on our LIBOR-based, SOFR-based and prime-based loans.

As of March 31, 2023, Great Southern’s interest rate risk models indicate that, generally, rising interest rates are expected to have a positive impact on the Company’s net interest income, while declining interest rates are expected to have a 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 LIBOR interest rates, 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 LIBOR interest rates, SOFR interest rates and “prime” interest rates. In the subsequent months, we expect that the net interest margin would stabilize and begin to improve, as renewal interest rates on maturing time deposits are expected to decrease compared to the current rates paid on those products.

During 2020, we did experience some compression of our net interest margin percentage due to 2.25% of 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 the 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 remains 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 has resulted in increasing loan yields and expansion of our net interest income and net interest margin. In 2023, market interest rate increases have moderated and loan yield increases have also 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.

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 Months Ended March 31, 2023 and 2022.”

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.

40

​

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.

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. 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 new ratio will be considered “well-capitalized” under the prompt corrective action rules. Currently, the CBLR is 9.0%. The Company and the Bank have chosen to not utilize the new 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

In January 2023, a high-transaction-volume banking center located at 1615 West Sunshine Street in Springfield, Missouri, was razed to make way for a new Express Center, which will use only interactive teller machine (ITM) technology to serve customers. The modern four-lane drive-up center is expected to open during the third quarter of 2023 and will be the first-of-its-kind in the Springfield market. ITMs, also known as video remote tellers, offer an ATM-like interface, but with the enhancement of a video screen that allows customers to speak directly to a service representative in real time and in a highly personal manner. Nearly any teller transaction that can be performed in the traditional drive-thru can be performed at an ITM, including cashing a check to the penny. ITMs provide convenience and enhanced access for customers, while creating greater operational efficiencies for the Bank.

A leased banking center office at 1232 S. Rangeline Road in Joplin, Missouri, was consolidated into a nearby office at 2801 E. 32nd Street. The leased office was closed at the end of the business day on March 17, 2023, leaving one banking center serving the Joplin market.

During 2023, the Great Southern team is preparing to convert to a new core banking platform and ancillary systems, delivered by a third party vendor. This upgrade in the operational platform is expected to provide new and advanced tools and access to more meaningful information to better serve customers. The migration to the new system is expected to occur in mid-2024. As significant preliminary work was completed in 2022 and early 2023, it was determined to extend the conversion timeline from third quarter 2023

41

​

to allow for further system testing related to some of our more highly-customized applications and products and to accommodate certain functionality enhancements to the platform.

The Company announced that its 2023 Annual Meeting of Stockholders, to be held at 10 a.m. Central Time on May 10, 2023, will be a virtual meeting over the internet and will not be held at a physical location. Stockholders will be able to attend the Annual Meeting via a live webcast. Holders of record of Great Southern Bancorp, Inc. common stock at the close of business on the record date, March 1, 2023, may vote during the live webcast of the Annual Meeting or by proxy.

Comparison of Financial Condition at March 31, 2023 and December 31, 2022

During the three months ended March 31, 2023, the Company’s total assets increased by $88.0 million to $5.77 billion. The increase was primarily in loans and interest-bearing deposits in other financial institutions.

Cash and cash equivalents were $184.7 million at March 31, 2023, an increase of $16.2 million, or 9.6%, from $168.5 million at December 31, 2022.

The Company’s available-for-sale securities increased $2.7 million, or 0.6%, compared to December 31, 2022. The increase was primarily due to an increase in the market value of these available-for-sale 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 8.6% of total assets at both March 31, 2023 and December 31, 2022.

Held-to-maturity securities were $200.4 million at March 31, 2023, a decrease of $2.1 million, or 1.0%, from $202.5 million at December 31, 2022. The held-to-maturity securities portfolio was 3.5% and 3.6% of total assets at March 31, 2023 and December 31, 2022, respectively.

Net loans increased $62.5 million from December 31, 2022, to $4.57 billion at March 31, 2023. This increase was primarily in other residential (multi-family) loans ($104 million increase) and commercial real estate loans ($30 million increase). These increases were partially offset by a decrease in commercial construction loans ($61 million decrease). Loan origination volume in the three months ended March 31, 2023 significantly decreased compared to the origination volume that occurred in 2021 and most of 2022; however, the pace of loan payoffs prior to maturity has slowed in the latter half of 2022 and into 2023 due to the significant increase in market rates of interest.

Total liabilities increased $65.6 million, from $5.15 billion at December 31, 2022 to $5.21 billion at March 31, 2023, primarily due to increases in brokered deposits and short-term borrowings from FHLBank. This was partially offset by a reduction in non-interest bearing checking accounts and national time deposits initiated through internet channels. Time deposits initiated through internet channels experienced a planned decrease as part of the Company’s balance sheet management between funding sources. In addition, securities sold under reverse repurchase agreements decreased $106 million in the three months ended March 31, 2023.

Total deposits increased $114.2 million, or 2.4%, to $4.80 billion at March 31, 2023. Transaction account balances decreased $26.3 million, from $3.25 billion at December 31, 2022 to $3.23 billion at March 31, 2023. Retail certificates of deposit increased $14.9 million compared to December 31, 2022, to $1.04 billion at March 31, 2023. Total interest-bearing checking accounts increased $45.8 million while non-interest-bearing checking accounts decreased $72.1 million. Customer retail time deposits initiated through our banking center network increased $36.7 million and time deposits initiated through our national internet network decreased $19.8 million. The increase in customer retail time deposits initiated through the banking center network was primarily due to targeted promotions that started in late June 2022 and continued from time to time into the first three months of 2023. Brokered deposits increased $125.5 million to $537.0 million at March 31, 2023, compared to $411.5 million at December 31, 2022. Brokered deposits were utilized to fund growth in outstanding loans and to offset reductions in balances in other deposit categories. The Company has the capacity to further expand its use of brokered deposits if it chooses to do so.

The Company’s term Federal Home Loan Bank advances were $-0- at both March 31, 2023 and December 31, 2022. At March 31, 2023 and December 31, 2022 there were overnight borrowings from the FHLBank, which are included in the short term borrowings category.

Securities sold under reverse repurchase agreements with customers decreased $106.1 million from $176.8 million at December 31, 2022 to $70.7 million at March 31, 2023. These balances fluctuate over time based on customer demand for this product. In March

42

​

2023, some customers elected to move funds from these repurchase accounts into other types of deposit accounts that included deposit insurance coverage through the IntraFi deposit program.

Short-term borrowings and other interest-bearing liabilities increased $66.1 million from $89.6 million at December 31, 2022 to $155.7 million at March 31, 2023. At March 31, 2023, $154.5 million of this total was overnight borrowings from the FHLBank, which was used to fund increases in outstanding loans.

Total stockholders’ equity increased $22.4 million, from $533.1 million at December 31, 2022 to $555.5 million at March 31, 2023. Accumulated other comprehensive loss decreased $11.9 million during the three months ended March 31, 2023, primarily due to increases in the fair value of available-for-sale investment securities and the fair value of cash flow hedges, as a result of decreased market interest rates. Stockholders’equity also increased due to net income of $20.5 million for the three months ended March 31, 2023 and a $470,000 increase in stockholders’ equity due to stock option exercises. Partially offsetting these increases were repurchases of the Company’s common stock totaling $5.6 million and dividends declared on common stock of $4.9 million.

Results of Operations and Comparison for the Three Months Ended March 31, 2023 and 2022

General

Net income was $20.5 million for the three months ended March 31, 2023 compared to $17.0 million for the three months ended March 31, 2022. This increase of $3.5 million, or 20.4%, was primarily due to an increase in net interest income of $9.9 million, or 22.9%, partially offset by an increase in non-interest expense of $3.2 million, or 10.2%, a decrease in non-interest income of $1.3 million, or 14.0%, an increase in income tax expense of $1.1 million, or 25.3%, and an increase in provision for credit losses on loans and unfunded commitments of $867,000, or 449.2%.

Total Interest Income

Total interest income increased $24.8 million, or 53.1%, during the three months ended March 31, 2023 compared to the three months ended March 31, 2022. The increase was due to a $22.4 million increase in interest income on loans and a $2.4 million increase in interest income on investment securities and other interest-earning assets. Interest income from loans, investment securities and other interest-earning assets increased during the three months ended March 31, 2023 compared to the same period in 2022 due to higher average balances and higher average rates of interest.

Interest Income – Loans

During the three months ended March 31, 2023 compared to the three months ended March 31, 2022, interest income on loans increased $16.9 million due to higher average interest rates on loans. The average yield on loans increased from 4.23% during the three months ended March 31, 2022, to 5.76% during the three months ended March 31, 2023. This increase was primarily due to the repricing of floating rate loans in the second half of 2022 and into 2023 as market interest rates increased significantly. Interest income on loans also increased $5.5 million as the result of higher average loan balances, which increased from $4.13 billion during the three months ended March 31, 2022, to $4.61 billion during the three months ended March 31, 2023. The Company continued to originate loans at a pace similar to prior periods through the first nine months of 2022, and overall loan repayments slowed in 2022 and 2023 compared to the level of repayments in 2021.

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 the $400 million notional 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 to date interest portion and net of deferred income taxes, is reflected in the Company’s stockholders’ equity as Accumulated Other Comprehensive Income and 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 periods. The Company recorded interest income related to the interest rate swap of $2.0 million in each of the three months ended March 31, 2023 and 2022. At March 31, 2023, 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 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 is $300 million with an effective date of March 1, 2022 and a

43

​

termination date of March 1, 2024. Under the terms of the swap, the Company will receive a fixed rate of interest of 1.6725% and will pay a floating rate of interest equal to one-month USD-LIBOR (or the equivalent replacement rate if USD-LIBOR rate is not available). The floating rate resets monthly and net settlements of interest due to/from the counterparty also occur monthly. The initial floating rate of interest was set at 0.2414%. To the extent that the fixed rate of interest exceeds one-month USD-LIBOR, the Company will receive net interest settlements, which will be recorded as loan interest income. If one-month USD-LIBOR exceeds the fixed rate of interest, the Company will be required to pay net settlements to the counterparty and will record those net payments as a reduction of interest income on loans. The Company recorded a reduction in loan interest income related to this swap transaction of $2.2 million in the three months ended March 31, 2023 and loan interest income related to this swap transaction of $370,000 in the three months ended March 31, 2022. At April 1, 2023, the one-month USD-LIBOR rate on this interest rate swap was 4.85771%.

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 will receive a fixed rate of interest of 2.628% and will pay 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 will receive a fixed rate of interest of 5.725% and will pay a floating rate of interest equal to one-month USD-Prime. In each case, the floating rate will be reset monthly and net settlements of interest due to/from the counterparty will also occur monthly. To the extent the fixed rate of interest exceeds the floating rate of interest, the Company will receive net interest settlements, which will be recorded as loan interest income. If the floating rate of interest exceeds the fixed rate of interest, the Company will be required to pay net settlements to the counterparty and will record those net payments as a reduction of interest income on loans. At March 31, 2023, the USD-Prime rate was 8.00% and the one-month USD-SOFR OIS rate was 4.62101%.

Interest Income – Investments and Other Interest-earning Assets

Interest income on investments increased $1.6 million in the three months ended March 31, 2023 compared to the three months ended March 31, 2022. Interest income increased $1.2 million as a result of an increase in average balances from $534.0 million during the three months ended March 31, 2022, to $706.9 million during the three months ended March 31, 2023. Average balances of securities increased primarily due to purchases of agency multi-family mortgage-backed securities which have a fixed rate of interest with expected lives of four to ten years, which fits with the Company’s current asset/liability management strategies. Interest income increased $400,000 as a result of higher average interest rates from 2.59% during the three months ended March 31, 2022, to 2.87% during the three month period ended March 31, 2023.

Interest income on other interest-earning assets increased $823,000 in the three months ended March 31, 2023 compared to the three months ended March 31, 2022. Interest income increased $850,000 as a result of higher average interest rates from 0.18% during the three months ended March 31, 2022, to 4.51% during the three months ended March 31, 2023. Partially offsetting that increase, interest income decreased $27,000 as a result of a decrease in average balances from $458.6 million during the three months ended March 31, 2022, to $91.8 million during the three months ended March 31, 2023. The increase in the average interest rates was due to the increase in the rate paid on funds held at the Federal Reserve Bank. This rate was increased multiple times in 2022 and 2023 in conjunction with the increase in the Federal Funds target interest rate. The decrease in average balances was due to utilization of these funds in loan originations and securities purchases.

Total Interest Expense

Total interest expense increased $14.9 million, or 436.3%, during the three months ended March 31, 2023, when compared with the three months ended March 31, 2022, due to an increase in interest expense on deposits of $12.5 million, or 574.2%, an increase in interest expense on short-term borrowings of $1.8 million, an increase in interest expense on securities sold under reverse repurchase agreements of $332,000, or 3320.0%, an increase in interest expense on subordinated debentures issued to capital trusts of $275,000, or 233.1%, and an increase in interest expense on subordinated notes of $1,000, or 0.1%.

Interest Expense – Deposits

Interest expense on demand and savings deposits increased $3.6 million due to average rates of interest that increased from 0.13% in the three months ended March 31, 2022 to 0.81% in the three months ended March 31, 2023. Interest rates paid on demand deposits were higher in the 2023 period due to significant increases in overall market rates. Partially offsetting this increase, interest expense on demand deposits decreased $57,000, due to a decrease in average balances from $2.38 billion during the three months ended March 31, 2022 to $2.18 billion during the three months ended March 31, 2023. The Company experienced decreased balances in various types of money market accounts, certain types of NOW accounts and IntraFi Network Reciprocal Deposits.

​

Interest expense on time deposits increased $3.7 million as a result of an increase in average rates of interest from 0.56% during the three months ended March 31, 2022, to 2.07% during the three months ended March 31, 2023. Interest expense on time deposits increased $247,000 due to an increase in average balances of time deposits from $863.7 million during the three months ended March 31, 2022 to $1.02 billion in the three months ended March 31, 2023. 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. Older certificates of deposit that renewed or were replaced with new deposits generally resulted in the Company paying a higher rate of interest due to increases in market interest rates throughout 2022 and targeted promotions during the latter half of 2022 and the first three months of 2023.

Interest expense on brokered deposits increased $3.3 million, due to an increase in average balances from $67.4 million during the three months ended March 31, 2022 to $456.8 million during the three months ended March 31, 2023. Interest expense on brokered deposits increased $1.6 million due to average rates of interest that increased from 1.17% in the three months ended March 31, 2022 to 4.53% in the three months ended March 31, 2023. Brokered deposits added during the three months ended March 31, 2023 were at higher market rates than brokered deposits previously issued. The Company uses brokered deposits of select maturities from time to time to supplement its various funding channels and to manage interest rate risk.

Interest Expense – FHLBank Advances; Short-term Borrowings, Repurchase Agreements and Other Interest-bearing Liabilities; Subordinated Debentures Issued to Capital Trusts and Subordinated Notes

FHLBank term advances were not utilized during the three months ended March 31, 2023 and 2022.

Interest expense on reverse repurchase agreements increased $330,000 due to higher average interest rates during the three months ended March 31, 2023 when compared to the three months ended March 31, 2022. The average rate of interest was 0.94% for the three months ended March 31, 2023 compared to 0.03% for the three months ended March 31, 2022. The average balance of repurchase agreements increased $18.7 million from $128.3 million in the three months ended March 31, 2022 to $147.0 million in the three months ended March 31, 2023, which was due to changes in customers’ desire for this product, which can fluctuate.

Interest expense on short-term borrowings (including overnight borrowings from the FHLBank) and other interest-bearing liabilities increased $1.1 million during the three months ended March 31, 2023 when compared to the three months ended March 31, 2022 due to higher average rates of interest. The average rate of interest was 4.75% for the three months ended March 31, 2023, compared to 0.08% for the three months ended March 31, 2022. Short-term market interest rates increased sharply throughout 2022 and into 2023. Interest expense on short-term borrowings (including overnight borrowings from the FHLBank) and other interest-bearing liabilities increased $722,000 during the three months ended March 31, 2023 when compared to the three months ended March 31, 2022 due to higher average balances. The average balance of short-term borrowings and other interest-bearing liabilities increased $148.2 million from $3.6 million in the three months ended March 31, 2022 to $151.8 million in the three months ended March 31, 2023, which was primarily due to changes in the Company’s funding needs and the mix of funding, which can fluctuate. Most of this increase was due to the utilization of overnight borrowings from the FHLBank.

During the three months ended March 31, 2023, compared to the three months ended March 31, 2022, interest expense on subordinated debentures issued to capital trusts increased $275,000 due to higher average interest rates. The average interest rate was 6.18% in the three months ended March 31, 2023 compared to 1.86% in the three months ended March 31, 2022. The subordinated debentures are variable-rate debentures which bear interest at an average rate of three-month LIBOR plus 1.60%, adjusting quarterly, which was 6.41% at March 31, 2023. There was no change in the average balance of the subordinated debentures between the 2022 and 2023 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. During the three months ended March 31, 2023, compared to the three months ended March 31, 2022, interest expense on subordinated notes increased $1,000.

Net Interest Income

Net interest income for the three months ended March 31, 2023 increased $9.9 million to $53.2 million compared to $43.3 million for the three months ended March 31, 2022. Net interest margin was 3.99% in the three months ended March 31, 2023, compared to 3.43% in the three months ended March 31, 2022, an increase of 56 basis points, or 16.3%. 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 and subordinated debentures issued to capital trust.

The Company’s overall average interest rate spread increased 22 basis points, or 6.6%, from 3.31% during the three months ended March 31, 2022 to 3.53% during the three months ended March 31, 2023. The increase was due to a 166 basis point increase in the weighted average yield on interest-earning assets, partially offset by a 144 basis point increase in the weighted average rate paid on interest-bearing liabilities. In comparing the two periods, the yield on loans increased 153 basis points, the yield on investment securities increased 28 basis points and the yield on other interest-earning assets increased 433 basis points. The rate paid on deposits increased 135 basis points, the rate paid on reverse repurchase agreements increased 91 basis points, the rate paid on short-term borrowings and other interest-bearing liabilities increased 467 basis points the rate paid on subordinated debentures issued to capital trusts increased 432 basis points.

Provision for and Allowance for Credit Losses

The Company adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, effective January 1, 2021. The CECL methodology replaced the incurred loss methodology with a lifetime “expected credit loss” measurement objective for loans, held-to-maturity debt securities and other receivables measured at amortized cost at the time the financial asset is originated or acquired. This standard requires the consideration of historical loss experience and current conditions adjusted for reasonable and supportable economic forecasts.

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 differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in economic conditions, such as changes in the national unemployment rate, commercial real estate price index, housing price index, consumer sentiment, gross domestic product (GDP) and construction spending.

Continued challenging or worsening economic conditions from COVID-19 and subsequent variant outbreaks or similar events, higher inflation or interest rates, 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 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, on-going correspondence with borrowers and problem loan work-outs. 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 March 31, 2023, the Company recorded provision expense of $1.5 million on its portfolio of outstanding loans. During the three months ended March 31, 2022, the Company did not record a provision expense on its portfolio of outstanding loans. The provision recorded during the three months ended March 31, 2023 was primarily due to increases in outstanding loan balances, combined with a modestly worsening economic forecast. In the three months ended March 31, 2023 and 2022, the Company experienced net recoveries of $7,000 and $43,000, respectively. The provision for losses on unfunded commitments for the three months ended March 31, 2023 and March 31, 2022 was a negative provision of $826,000 and $193,000, respectively. 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 level of provisions and charge-offs.

The Bank’s allowance for credit losses as a percentage of total loans was 1.40% and 1.39% at March 31, 2023 and December 31, 2022, respectively. Management considers the allowance for credit losses adequate to cover losses inherent in the Bank’s loan portfolio at March 31, 2023, based on recent reviews of the Bank’s loan portfolio and current economic conditions. If challenging

​

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

At March 31, 2023, non-performing assets were $3.0 million, a decrease of $693,000 from $3.7 million at December 31, 2022. Non-performing assets as a percentage of total assets were 0.05% at March 31, 2023, compared to 0.07% at December 31, 2022.

Compared to December 31, 2022, non-performing loans decreased $688,000, to $3.0 million at March 31, 2023, and foreclosed and repossessed assets decreased $5,000, to $45,000 at March 31, 2023. The majority of the decrease in non-performing loans was in the commercial business loans category, which decreased $570,000 from December 31, 2022.

Non-performing Loans. Activity in the non-performing loans category during the three months ended March 31, 2023 was as follows:

​

At March 31, 2023, the non-performing commercial real estate category included three loans, none of which were added during the current period. The largest relationship in the category, which totaled $1.3 million, or 82.8% of the total category, was transferred from potential problem loans during 2021, and is collateralized by a mixed-use commercial retail building. Although considered non-performing, periodic payments have been received on this relationship. The non-performing one- to four-family residential category included 20 loans, none of which were added during the current period. The largest relationship in the category totaled $155,000, or 24.8% of the category. The non-performing land development category consisted of one loan added during 2021, which totaled $384,000 and is collateralized by unimproved zoned vacant ground in southern Illinois. The non-performing commercial business category consisted of one loan, which was added during the current period. The balance in this category was reduced by $586,000 due to the repayment in full of the one existing relationship at the beginning of the current period. The non-performing consumer category included 21 loans, five of which were added during the current period.

​

Potential Problem Loans. Compared to December 31, 2022, potential problem loans decreased $961,000, or 60.9%, to $617,000 at March 31, 2023. The decrease during the period was primarily due to multiple loans totaling $1.0 million that were upgraded to a satisfactory risk rating, $117,000 in loan payments and $12,000 in charge offs, partially offset by $174,000 in loans added to potential problem loans. 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 categories during the three months ended March 31, 2023, was as follows:

​

At March 31, 2023, the one- to four-family residential category of potential problem loans included five loans, two of which were added during the current period. The largest relationship in this category totaled $143,000, or 29.2% of the total category. During the three months ending March 31, 2023, 17 loans, totaling $939,000, met the criteria to be upgraded to a satisfactory risk rating. The consumer category of potential problem loans included 13 loans, one of which was added during the current period.

Other Real Estate Owned and Repossessions. Of the total $154,000 of other real estate owned and repossessions at March 31, 2023, $109,000 represents properties which were not acquired through foreclosure.

Activity in foreclosed assets and repossessions during the three months ended March 31, 2023, was as follows:

Loans Classified “Watch”

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.” Loans classified as “Watch” are being monitored because of indications of potential weaknesses or deficiencies that may require future classification as special mention or substandard. In the three months ended March 31, 2023, loans classified as “Watch” decreased $10.3 million, from $28.7 million at December 31, 2022 to $18.4 million at March 31, 2023, primarily due to loans being upgraded out of the “Watch” category. See Note 6 for further discussion of the Company’s loan grading system.

Non-interest Income

For the three months ended March 31, 2023, non-interest income decreased $1.3 million to $7.9 million when compared to the three months ended March 31, 2022, primarily as a result of the following items:

Net gains on loan sales: Net gains on loan sales decreased $745,000 compared to the prior year period. The decrease was due to a decrease in originations of fixed-rate single-family mortgage loans during the 2023 period compared to the 2022 period. Fixed rate single-family mortgage loans originated are generally subsequently sold in the secondary market. These loan originations increased substantially when market interest rates decreased to historically low levels in 2020 and 2021. As a result of the significant volume of refinance activity in 2020 and 2021, and as market interest rates moved higher beginning in the second quarter of 2022, mortgage refinance volume decreased and fixed rate loan originations and related gains on sales of these loans decreased substantially. The lower level of originations is expected to continue as long as market rates remain elevated.

Gain (loss) on derivative interest rate products: In the 2023 period, the Company recognized a loss of $291,000 on the change in fair value of its back-to-back interest rate swaps related to commercial loans and the change in fair value on interest rate swaps related to brokered time deposits. In the 2022 period, the Company recognized a gain of $152,000 on the change in fair value of its back-to-back interest rate swaps related to commercial loans. Changes in the fair value of these types of swaps generally relate to movements in market interest rates during the period and the cumulative changes in these fair values will ultimately total zero at maturity of the swaps.

Non-interest Expense

For the three months ended March 31, 2023, non-interest expense increased $3.2 million to $34.5 million when compared to the three months ended March 31, 2022, primarily as a result of the following items:

Legal, Audit and Other Professional Fees: Legal, audit and other professional fees increased $1.2 million from the prior year period, to $2.0 million. In the 2023 period, the Company expensed a total of $1.3 million related to training and implementation costs for the upcoming core systems conversion and professional fees to consultants engaged to support the Company’s transition of core and ancillary software and information technology systems.

Salaries and employee benefits: Salaries and employee benefits increased $1.1 million from the prior year period. A portion of this increase related to normal annual merit increases in various lending and operations areas. In the 2023 period, some of these increases were larger than in previous periods due to the current employment environment. In addition, the Charlotte commercial loan office was opened in the second quarter of 2022 and therefore had no expense in the first quarter of 2022. The operation of this office added approximately $85,000 of salaries and benefits expense in the three months ended March 31, 2023. In addition, compensation costs related to originated loans which are deferred under accounting rules, decreased by $350,000 in the 2023 period compared to the 2022 period, due to lower origination volumes.

Net occupancy expenses: Net occupancy expenses increased $842,000 from the prior year period. Various components of computer license and support increased by $500,000 in the 2023 period compared to the 2022 period. In addition, repairs and maintenance on various buildings and ATMs increased by $250,000 in the 2023 period compared to the 2022 period.

​

The Company’s efficiency ratio for the three months ended March 31, 2023, was 56.42% compared to 59.62% for the same period in 2022. The improved efficiency ratio was primarily due to an increase in net interest income, partially offset by an increase in non-interest expense. The Company’s ratio of non-interest expense to average assets was 2.42% and 2.34% for the three months ended March 31, 2023 and 2022, respectively. Average assets for the three months ended March 31, 2023, increased $358.0 million, or 6.7%, from the three months ended March 31, 2022, primarily due to an increase in net loans receivable and investment securities, partially offset by a decrease in interest bearing cash equivalents.

Provision for Income Taxes

For the three months ended March 31, 2023 and 2022, the Company’s effective tax rate was 21.2% 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’s effective income tax rate is currently generally expected to remain near the statutory federal tax rate due primarily to the factors noted above. The Company currently expects its effective tax rate (combined federal and state) will be approximately 20.5% to 21.5% in future periods.

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 $1.3 million and $1.7 million for the three months ended March 31, 2023 and 2022, 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 management of its 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 March 31, 2023, the Company had commitments of approximately $60.2 million to fund loan originations, $1.89 billion of unused lines of credit and unadvanced loans, and $16.6 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, FHLBank advances, other borrowings, loan repayments, unpledged securities, proceeds from sales of loans and available-for-sale securities and funds provided from operations. The Company utilizes particular sources of funds based 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.

At March 31, 2023 and December 31, 2022, the Company had the following available secured lines and on-balance sheet liquidity:

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | March 31, 2023 |  | December 31, 2022

​

Statements of Cash Flows. During the three months ended March 31, 2023 and 2022, the Company had positive cash flows from operating activities. The Company had negative cash flows from investing activities during the three months ended March 31, 2023 and 2022. The Company had positive cash flows from financing activities during the three months ended March 31, 2023 and negative cash flows from financing activities during the three months ended March 31, 2022.

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

53

​

and the origination and sale of loans held for sale were the primary source of cash flows from operating activities. Operating activities provided cash flows of $5.4 million and $31.4 million during the three months ended March 31, 2023 and 2022, respectively.

During the three months ended March 31, 2023 and 2022, investing activities used cash of $53.4 million and $318.4 million, respectively. Investing activities in the 2023 period used cash primarily due to the net originations of loans. Investing activities in the 2022 period used cash primarily due to the purchase of investment securities, the purchases of loans and the net origination of loans, partially offset by payments received on investment securities.

Changes in cash flows from financing activities during the periods covered by the Statements of Cash Flows were due 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, repurchases of the Company’s common stock and the exercise of common stock options. During the three months ended March 31, 2023 and 2022, financing activities provided cash of $64.1 million and used cash of $77.2 million, respectively. In the 2023 period, financing activities provided cash primarily as a result of net increases in time deposits and checking and savings deposits, partially offset by decreases in short-term borrowings, the repurchase of the Company’s common stock and dividends paid to stockholders. In the 2022 period, financing activities used cash primarily as a result of net decreases in time deposits, dividends paid to stockholders and the purchase of the Company’s common stock, partially offset by net increases in short-term borrowings.

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 March 31, 2023, the Company’s total stockholders’ equity and common stockholders’ equity were each $555.5 million, or 9.6% of total assets, equivalent to a book value of $45.78 per common share. As of December 31, 2022, total stockholders’ equity and common stockholders’ equity were each $533.1 million, or 9.4% of total assets, equivalent to a book value of $43.58 per common share. At March 31, 2023, the Company’s tangible common equity to tangible assets ratio was 9.5%, compared to 9.2% at December 31, 2022 (See Non-GAAP Financial Measures below).

Included in stockholders’ equity at March 31, 2023 and December 31, 2022, were unrealized losses (net of taxes) on the Company’s available-for-sale investment securities totaling $40.3 million and $47.2 million, respectively. This change in net unrealized loss during the three months ended March 31, 2023, primarily resulted from decreasing intermediate-term market interest rates, which generally increased the fair value of investment securities. Also included in stockholders’ equity at March 31, 2023, were unrealized gains (net of taxes) totaling $72,000 on the Company’s investment securities that were transferred to the held-to-maturity category. Approximately $227 million of investment securities previously included in available-for-sale were transferred to held-to-maturity during the first quarter of 2022.

In addition, included in stockholders’ equity at March 31, 2023, were realized gains (net of taxes) on the Company’s terminated cash flow hedge (interest rate swap), totaling $15.8 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 March 31, 2023, the remaining pre-tax amount to be recorded in interest income was $20.5 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 March 31, 2023, was an unrealized loss (net of taxes) on the Company’s outstanding cash flow hedges (interest rate swaps) totaling $17.0 million. Increases in market interest rates since the inception of these hedges have caused their fair values to decrease. However, during the three months ended March 31, 2023, decreasing forward swap rates resulted in increasing fair values of these hedges.

As noted above, total stockholders’ equity increased $22.4 million, from $533.1 million at December 31, 2022 to $555.5 million at March 31, 2023. Accumulated other comprehensive income increased $11.9 million during the three months ended March 31, 2023, primarily due to increases in the fair value of available-for-sale investment securities and the fair value of cash flow hedges. Stockholders’ equity also increased due to net income of $20.5 million for the three months ended March 31, 2023 and a $470,000 increase due to stock option exercises. Partially offsetting these increases were repurchases of the Company’s common stock totaling $5.6 million and dividends declared on common stock of $4.9 million.

The Company also had unrealized losses on its portfolio of held-to-maturity investment securities, which totaled $20.6 million at March 31, 2023, that were not included in its total capital balance. If these held-to-maturity unrealized losses were included in capital

54

​

(net of taxes) it would have decreased total stockholder’s equity by $15.5 million at March 31, 2023. This amount was equal to 2.8% of total stockholders’ equity of $555.5 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 March 31, 2023, the Bank’s common equity Tier 1 capital ratio was 12.3%, its Tier 1 risk-based capital ratio was 12.3%, its total risk-based capital ratio was 13.5% and its Tier 1 leverage ratio was 11.7%. As a result, as of March 31, 2023, the Bank was well capitalized, with capital ratios in excess of those required to qualify as such. On December 31, 2022, the Bank’s common equity Tier 1 capital ratio was 11.9%, its Tier 1 risk-based capital ratio was 11.9%, its total risk-based capital ratio was 13.1% and its Tier 1 leverage ratio was 11.5%. As a result, as of December 31, 2022, 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 March 31, 2023, the Company’s common equity Tier 1 capital ratio was 10.9%, its Tier 1 risk-based capital ratio was 11.3%, its total risk-based capital ratio was 13.9% and its Tier 1 leverage ratio was 10.8%. To be considered well capitalized, a bank holding company must have a Tier 1 risk-based capital ratio of at least 6.00% and a total risk-based capital ratio of at least 10.00%. As of March 31, 2023, the Company was considered well capitalized, with capital ratios in excess of those required to qualify as such. On December 31, 2022, the Company’s common equity Tier 1 capital ratio was 10.6%, its Tier 1 risk-based capital ratio was 11.0%, its total risk-based capital ratio was 13.5% and its Tier 1 leverage ratio was 10.6%. As of December 31, 2022, the Company was considered well capitalized, with capital ratios in excess of those required to qualify as such.

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 March 31, 2023, the Company and the Bank both had additional common equity Tier 1 capital in excess of the buffer amount.

Dividends. During the three months ended March 31, 2023, the Company declared a common stock cash dividend of $0.40 per share, or 24% 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 December 2022). During the three months ended March 31, 2022, the Company declared a common stock cash dividend of $0.36 per share, or 28% of net income per diluted common share for that three month period, and paid a common stock cash dividend of $0.36 per share (which was declared in December 2021). 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 March 31, 2023, was paid to stockholders in April 2023.

Common Stock Repurchases and Issuances. The Company has been in various buy-back programs since May 1990. During the three months ended March 31, 2023, the Company repurchased 99,121 shares of its common stock at an average price of $55.70 per share and issued 1,717 shares of common stock at an average price of $43.05 per share to cover stock option exercises. During the three months ended March 31, 2022, the Company repurchased 419,215 shares of its common stock at an average price of $60.40 per share and issued 51,694 shares of common stock at an average price of $47.49 per share to cover stock option exercises.

In January 2022, the Company’s Board of Directors authorized management to purchase up to one million shares of the Company’s outstanding common stock, under a program of open market purchases or privately negotiated transactions. At March 31, 2023, there were approximately 78,000 shares which could still be purchased under this authorization. In December 2022, the Company’s Board of Directors authorized the purchase of up to an additional one million shares of the Company’s outstanding common stock, under a program of open market purchases or privately negotiated transactions, resulting in a total of approximately 1.1 million shares available in our stock repurchase authorization as of March 31, 2023.

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

56

​

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 March 31, 2023, Great Southern’s interest rate risk models indicate that, generally, rising interest rates are expected to have a positive impact on the Company’s net interest income, while declining interest rates are expected to have a 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 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 LIBOR/SOFR interest rates (or their replacement 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 LIBOR/SOFR interest rates (or their replacement rates) and “prime” interest rates. In the subsequent months we expect that the net interest margin would stabilize and begin to improve, as renewal interest rates on maturing time deposits are expected to decrease compared to the then-current rates paid on those products. During 2020, we did experience some compression of our net interest margin percentage due to the Federal Fund rate being cut by a total of 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 the 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 and may increase further in the first half of 2023. 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 seen in the first quarter of 2023. In the first three months of 2023, competition for deposits was very intense, resulting in significant increases in rates paid on various deposit types. Subsequent to March 31, 2023, cumulative time deposit maturities are as follows: within three months -- $511 million; within six months -- $686 million; and within twelve months -- $1.04 billion. At March 31, 2023, the weighted average interest rates on these various cumulative maturities were 2.08%, 2.17% and 2.44%, respectively. Based on time deposit market rates in April 2023, replacement rates for these maturing time deposits are likely to be near or exceed 4.00%.

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% and 0.25% in February and March 2023, respectively. At March 31, 2023 the Federal Funds rate was 5.00%. Financial markets expect the possibility of further increases in Federal Funds interest rates in the first half of 2023, with 0.25-0.50% of additional cumulative rate hikes currently anticipated. A substantial portion of Great Southern’s loan portfolio ($868.8 million at March 31, 2023) is tied to the one-month or three-month LIBOR index and will be subject to adjustment at least once within 90 days after March 31, 2023. Of these loans, $868.5 million had interest rate floors. Great Southern’s loan portfolio also includes loans ($693.4 million at March 31, 2023) tied to various SOFR indexes that will be subject to adjustment at least once within 90 days after March 31, 2023. Of these loans, $693.4 million had interest rate floors. Great Southern also has a portfolio of loans ($738.6 million at March 31, 2023) tied to a “prime rate” of interest that will adjust immediately or within 90 days of a change to the “prime rate” of interest. Of these loans, $725.8 million had interest rate floors at various rates. Great Southern also has a portfolio of loans ($6.7 million at March 31, 2023) tied to an AMERIBOR index that will adjust immediately or within 90 days of a change to the “prime rate” of interest. Of these loans, $6.7 million had interest rate floors at various rates. At March 31, 2023, nearly all of these LIBOR/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.

​

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 potentially 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. 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-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. 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.

58

​

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 is $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 will receive a fixed rate of interest of 1.6725% and will pay a floating rate of interest equal to one-month USD-LIBOR. The floating rate will be reset monthly and net settlements of interest due to/from the counterparty will also occur monthly. The initial floating rate of interest was set at 0.24143%. The Company will receive net interest settlements, which will be recorded as loan interest income, to the extent that the fixed rate of interest exceeds one-month USD-LIBOR. If USD-LIBOR exceeds the fixed rate of interest in future periods, the Company will be required to pay net settlements to the counterparty and will record 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 will receive a fixed rate of interest of 2.628% and will pay 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 will receive a fixed rate of interest of 5.725% and will pay a floating rate of interest equal to one-month USD-Prime. In each case, the floating rate will be reset monthly and net settlements of interest due to/from the counterparty will also occur monthly. To the extent the fixed rate of interest exceeds the floating rate of interest, the Company will receive net interest settlements, which will be recorded as loan interest income. If the floating rate of interest exceeds the fixed rate of interest, the Company will be required to pay net settlements to the counterparty and will record those net payments as a reduction of interest income on loans.

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 March 31, 2023, 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 March 31, 2023, 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 March 31, 2023, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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.
