Great Southern Bancorp, Inc. Reports Preliminary Second Quarter Earnings of

$1.45 Per Diluted Common Share

Preliminary Financial Results and Other Matters for the Quarter and Six Months Ended June 30, 2024:

(1) an expense in Legal and Professional Fees totaling $902,000 related to training and implementation costs for the core systems conversion and professional fees to consultants that were engaged to support the Company in its transition of core and ancillary software and information technology systems.

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

(3) an expense in Other Operating Expenses totaling $600,000 related to ongoing compliance matters.

Springfield, Mo. – Great Southern Bancorp, Inc. (NASDAQ:GSBC), the holding company for Great Southern Bank, today reported that preliminary earnings for the three months ended June 30, 2024, were $1.45 per diluted common share ($17.0 million net income) compared to $1.52 per diluted common share ($18.3 million net income) for the three months ended June 30, 2023.

Preliminary earnings for the six months ended June 30, 2024, were $2.58 per diluted common share ($30.4 million net income) compared to $3.19 per diluted common share ($38.8 million net income) for the six months ended June 30, 2023.

For the quarter ended June 30, 2024, annualized return on average common equity was 12.03%, annualized return on average assets was 1.17%, and annualized net interest margin was 3.43%, compared to 13.11%, 1.28% and 3.56%, respectively, for the quarter ended June 30, 2023. For the six months ended June 30, 2024, annualized return on average common equity was 10.69%, annualized return on average assets was 1.05%, and annualized net interest margin was 3.38%, compared to 13.99%, 1.36% and 3.77%, respectively, for the six months ended June 30, 2023.

Great Southern President and CEO Joseph W. Turner said, “Our second quarter results reflected improved earnings, both on a reported basis and excluding certain significant or non-recurring items, as we continue to operate in a challenging economic environment. Great Southern reported earnings of $1.45 per diluted common share ($17.0 million) for the second quarter of 2024, compared to $1.52 per diluted common share ($18.3 million) for the second quarter of 2023, and $1.13 per diluted common share ($13.4 million) for the first quarter of 2024. The significant or non-recurring items previously highlighted increased earnings per diluted common share by $0.08 for the second quarter of 2024. Reflective of current market interest rate and credit conditions, key drivers of our performance included modest increases in overall funding costs, continued significant competition for deposits and lower loan origination volume. We did see improved net interest income in the second quarter of 2024 compared to the first quarter of 2024 due to the contractual termination of an interest rate swap. Total non-interest income, excluding one non-recurring item discussed above, was slightly higher compared to the first quarter of 2024, mainly driven by increased gains on loan sales and better debit card transaction fee income. Total non-interest expense compared to the year ago second quarter increased about 3.5%.

“Like most banks, we experienced overall significantly higher funding costs during the second quarter of 2024 compared to the second quarter of 2023, primarily due to current market interest rates and competitive pressures. While deposit interest expenses increased, the pace of the increase has moderated over the last few quarters and only increased modestly compared to the first quarter of 2024. Net interest income in the second quarter of 2024 was approximately $1.3 million lower compared to the second quarter of 2023, and about $2.0 million higher compared to the first quarter of 2024. Higher funding costs in the second quarter of 2024 were partially caused by lower deposit balances with increased borrowings. As noted, an interest rate swap contractually terminated March 1, 2024, which reduced interest income by $1.9 million in the first quarter of 2024, with no financial impact from this swap in the second quarter of 2024.”

Turner added, “Total outstanding loan balances have increased about $44 million since the end of 2023. The increases primarily occurred in other residential (multi-family) loans, where much of the increase reflected the movement of completed projects from the construction loan category. At the end of June 2024, the pipeline of loan commitments and unfunded lines decreased to $1.1 billion, including $571 million in the unfunded portion of construction loans. Overall credit quality metrics remained strong during the quarter, with total non-performing assets remaining generally unchanged from March 2024. Non-performing assets to total assets were 0.34% at June 30, 2024 versus 0.20% at December 31, 2023. Compared to the end of 2023, non-performing assets increased $8.6 million to $20.4 million at the end of June 2024. Delinquencies in our loan portfolio remained at low levels and net charge-offs were not significant in the first half of 2024.

“The Company’s capital and liquidity positions remain strong. Total stockholders’ equity was $568.8 million as of June 30, 2024, decreasing by $3.0 million from the end of 2023 due to increases in unrealized losses on available-for-sale investment securities and interest rate swaps. Our capital remains substantially above regulatory well-capitalized thresholds. Our tangible common equity ratio was 9.4% at June 30, 2024. During the first six months of 2024, our Board declared two quarterly dividends, each at $0.40 per common share, and the Company continued to repurchase shares of its common stock, with approximately 237,000 shares repurchased at an average price of $51.67.

“In terms of liquidity, the Company had available secured funding lines through the FHLBank and Federal Reserve Bank, along with on-balance sheet liquidity totaling approximately $2.0 billion as of June 30, 2024. Great Southern’s deposit base remained diverse in terms of customer type and geography, with a relatively low level of uninsured deposits as of June 30, 2024 (approximately 14% of total deposits, excluding internal subsidiary accounts).”

Selected Financial Data:

NET INTEREST INCOME

Net interest income for the second quarter of 2024 decreased $1.3 million to $46.8 million, compared to $48.1 million for the second quarter of 2023. Net interest margin was 3.43% in the second quarter of 2024, compared to 3.56% in the same period of 2023, a decrease of 13 basis points. For the three months ended June 30, 2024, net interest margin increased 11 basis points compared to net interest margin of 3.32% in the three months ended March 31, 2024. In comparing the 2024 and 2023 second quarter periods, the average yield on loans increased 53 basis points, the average yield on investment securities increased 23 basis points and the average yield on other interest earning assets increased 38 basis points. The margin contraction primarily resulted from increasing interest rates on all deposit types due to higher market interest rates and increased competition for deposits. The average rate on interest-bearing demand and savings deposits, time deposits and brokered deposits increased 51 basis points, 123 basis points and 28 basis points, respectively, in the three months ended June 30, 2024 compared to the three months ended June 30, 2023. The average interest rate spread was 2.77% for the three months ended June 30, 2024, compared to 2.96% for the three months ended June 30, 2023 and 2.66% for the three months ended March 31, 2024. The ratio of average interest-earning assets to average interest-bearing liabilities decreased from 131.6% in the three months ended June 30, 2023, to 126.7% in the three months ended June 30, 2024.

Net interest income for the six months ended June 30, 2024 decreased $9.7 million to $91.6 million, compared to $101.3 million for the six months ended June 30, 2023. Net interest margin was 3.38% in the six months ended June 30, 2024, compared to 3.77% in the same period of 2023, a decrease of 39 basis points. The margin contraction primarily resulted from increasing interest rates on all deposit types due to higher market interest rates and increased competition for deposits. The average rate on interest-bearing demand and savings deposits, time deposits and brokered deposits increased 71 basis points, 154 basis points and 46 basis points, respectively, in the six months ended June 30, 2024 compared to the six months ended June 30, 2023. The average interest rate spread was 2.71% for the six months ended June 30, 2024, compared to 3.24% for the six months ended June 30, 2023.

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, on March 2, 2020, the Company and its swap counterparty mutually agreed to terminate this swap, effective immediately. The Company was paid $45.9 million, including accrued but unpaid interest, from its swap counterparty as a result of this termination. This $45.9 million, less the accrued to date interest portion and net of deferred income taxes, is reflected in the Company’s stockholders’ equity as part of Accumulated Other Comprehensive Income (AOCI) and is being accreted to interest income on loans monthly through the original contractual termination date of October 6, 2025. The Company recorded $2.0 million of interest income related to the swap in both the three months ended June 30, 2024 and the three months ended June 30, 2023. The Company recorded $4.1 million of interest income related to the swap in the six months ended June 30, 2024 and $4.0 million of interest income in the six months ended June 30, 2023. The Company currently expects to have a sufficient amount of eligible variable rate loans to continue to accrete this interest income ratably in future periods. If this expectation changes and the amount of eligible variable rate loans decreases significantly, the Company may be required to recognize this interest income more rapidly.

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

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

The Company’s net interest income was negatively impacted in the second quarter of 2024 by the high level of competition for deposits across the industry and the lingering effects of liquidity events at several banks in March and April 2023. The Company also had a substantial amount of time deposits maturing at relatively low rates after the second quarter of 2023, and these time deposits either renewed at higher rates or left the Company, in turn requiring their replacement with other funding sources at then-current higher market rates. As of June 30, 2024, time deposit maturities over the next 12 months were as follows: within three months -- $463 million, with a weighted-average rate of 4.46%; within three to six months -- $412 million, with a weighted-average rate of 4.47%; and within six to twelve months -- $259 million, with a weighted-average rate of 3.98%. Based on time deposit market rates in June 2024, replacement rates for these maturing time deposits are likely to be approximately 4.00-4.35%.

For additional information on net interest income components, see the “Average Balances, Interest Rates and Yields” tables in this release.

NON-INTEREST INCOME

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

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

NON-INTEREST EXPENSE

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

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

The Company’s efficiency ratio for the quarter ended June 30, 2024, was 64.27% compared to 62.10% for the same quarter in 2023. The Company’s efficiency ratio for the six months ended June 30, 2024, was 65.42% compared to 59.13% for the same period in 2023. The Company’s ratio of non-interest expense to average assets was 2.50% and 2.44% for the three- and six-months ended June 30, 2024, respectively, compared to 2.43% and 2.42% for the three- and six-months ended June 30, 2023, respectively. Average assets for the three months ended June 30, 2024, increased $110.2 million, or 1.9%, compared to the three months ended June 30, 2023, primarily due to increases in net loans receivable and non-interest-earning assets. Average assets for the six months ended June 30, 2024, increased $84.0 million, or 1.5%, compared to the six months ended June 30, 2023, primarily due to increases in net loans receivable and non-interest-earning assets.

INCOME TAXES

For the three months ended June 30, 2024 and 2023, the Company's effective tax rate was 18.5% and 19.7%, respectively. For the six months ended June 30, 2024 and 2023, the Company's effective tax rate was 18.8% and 20.5%, respectively. These effective rates were at 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 are analyzed. The Company's effective income tax rate is currently generally expected to remain below 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 18.5% to 20.0% in future periods, primarily due to additional investment tax credits utilized beginning in 2024.

CAPITAL

As of June 30, 2024, total stockholders’ equity and common stockholders’ equity were each $568.8 million (9.6% of total assets), equivalent to a book value of $49.11 per common share. Total stockholders’ equity and common stockholders’ equity at December 31, 2023, were each $571.8 million (9.8% of total assets), equivalent to a book value of $48.44 per common share. At June 30, 2024, the Company’s tangible common equity to tangible assets ratio was 9.4%, compared to 9.7% at December 31, 2023. See “Non-GAAP Financial Measures.” Included in stockholders’ equity at June 30, 2024 and December 31, 2023, were unrealized losses (net of taxes) on the Company’s available-for-sale investment securities totaling $47.3 million and $40.5 million, respectively. This change in net unrealized losses during the six months ended June 30, 2024, primarily resulted from increasing intermediate-term market interest rates (which generally decreased the fair value of investment securities) during the first six months of 2024.

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

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

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

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

On a preliminary basis, as of June 30, 2024, the Company’s Tier 1 Leverage Ratio was 11.0%, Common Equity Tier 1 Capital Ratio was 12.0%, Tier 1 Capital Ratio was 12.5%, and Total Capital Ratio was 15.2%.

On June 30, 2024, and on a preliminary basis, the Bank’s Tier 1 Leverage Ratio was 11.4%, Common Equity Tier 1 Capital Ratio was 13.0%, Tier 1 Capital Ratio was 13.0%, and Total Capital Ratio was 14.2%.

In December 2022, the Company’s Board of Directors authorized the purchase of an additional one million shares of the Company’s common stock. As of June 30, 2024, a total of approximately 490,000 shares were available in our stock repurchase authorization.

During the three months ended June 30, 2024, the Company repurchased 124,600 shares of its common stock at an average price of $51.88, and the Company’s Board of Directors declared a regular quarterly cash dividend of $0.40 per common share, which, combined, reduced stockholders’ equity by $11.2 million. During the six months ended June 30, 2024, the Company repurchased 236,962 shares of its common stock at an average price of $51.67, and the Company’s Board of Directors declared regular quarterly cash dividends totaling $0.80 per common share, which, combined, reduced stockholders’ equity by $21.7 million.

LIQUIDITY AND DEPOSITS

Liquidity is a measure of the Company’s ability to generate sufficient cash to meet present and future financial obligations in a timely manner. Liquid assets include cash, interest-bearing deposits with financial institutions and certain investment securities and loans. As a result of the Company’s ability to generate liquidity primarily through liability funding, management believes that the Company maintains overall liquidity sufficient to satisfy its depositors’ requirements and meet its borrowers’ credit needs.

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 some or all of these sources of funds depending on the comparative costs and availability at the time. The Company has from time to time chosen not to pay rates on deposits as high as the rates paid by certain of its competitors and, when believed to be appropriate, supplements deposits with less expensive alternative sources of funds.

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

During the three months ended June 30, 2024, the Company’s total deposits decreased $158.1 million. Interest-bearing checking balances decreased $104.7 million (about 4.6%), primarily in certain money market accounts and NOW accounts, while non-interest-bearing checking balances decreased $6.4 million (about 0.7%). Time deposits generated through the Company’s banking center and corporate services networks decreased $24.1 million (about 2.7%) and time deposits generated through internet channels decreased $4.7 million (about 33.9%). Brokered deposits decreased $15.5 million (about 2.3%) through a variety of sources.

During the six months ended June 30, 2024, the Company’s total deposits decreased $106.4 million. Interest-bearing checking balances decreased $25.5 million (about 1.2%) and non-interest-bearing checking balances decreased $25.3 million (about 2.8%). Time deposits generated through the Company’s banking center and corporate services networks decreased $53.9 million (about 5.8%) and time deposits generated through internet channels decreased $7.7 million (about 45.4%). Brokered deposits increased $8.5 million (about 1.3%) through a variety of sources.

At June 30, 2024, the Company had the following deposit balances:

LOANS

Total net loans, excluding mortgage loans held for sale, increased $44.0 million, or 1.0%, from $4.59 billion at December 31, 2023 to $4.63 billion at June 30, 2024. This increase was primarily in other residential (multi-family) loans ($309 million increase), partially offset by decreases in construction loans ($162 million decrease), commercial business loans ($62 million decrease) and one- to four-family residential loans ($26 million decrease). The pipeline of loan commitments declined in the second quarter of 2024. The unfunded portion of construction loans remained significant, but also declined, in the second quarter of 2024. As construction projects were completed, the related loans were either moved from the construction category to the appropriate permanent loan categories or paid off.

For further information about the Company’s loan portfolio, please see the quarterly loan portfolio presentation available on the Company’s Investor Relations website under “Presentations.”

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

PROVISION FOR CREDIT LOSSES AND ALLOWANCE FOR CREDIT LOSSES

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

Challenging or worsening economic conditions from higher inflation or interest rates, COVID-19 and subsequent variant outbreaks or similar events, global unrest or other factors may lead to increased losses in the portfolio and/or requirements for an increase in provision expense. Management maintains various controls in an attempt to identify and limit future losses, such as a watch list of problem loans and potential problem loans, documented loan administration policies and loan review staff to review the quality and anticipated collectability of the portfolio. Additional procedures provide for frequent management review of the loan portfolio based on loan size, loan type, delinquencies, financial analysis, ongoing correspondence with borrowers and problem loan workouts. Management determines which loans are collateral-dependent, evaluates risk of loss and makes additional provisions to expense, if necessary, to maintain the allowance at a satisfactory level.

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

The Bank’s allowance for credit losses as a percentage of total loans was 1.39%, 1.39% and 1.40% at June 30, 2024, December 31, 2023 and March 31, 2024, respectively. Management considers the allowance for credit losses adequate to cover losses inherent in the Bank’s loan portfolio at June 30, 2024, based on recent reviews of the Bank’s loan portfolio and current economic conditions. If challenging economic conditions were to last longer than anticipated or deteriorate further or management’s assessment of the loan portfolio were to change, additional credit loss provisions could be required, thereby adversely affecting the Company’s future results of operations and financial condition.

ASSET QUALITY

At June 30, 2024, non-performing assets were $20.4 million, an increase of $8.6 million from $11.8 million at December 31, 2023. Non-performing assets as a percentage of total assets were 0.34% at June 30, 2024, compared to 0.20% at December 31, 2023. Non-performing assets were $21.3 million at March 31, 2024. One loan relationship, totaling $9.3 million, was transferred from non-performing loans to foreclosed assets held for sale in the three months ended June 30, 2024. As a result of changes in loan portfolio composition, changes in economic and market conditions and other factors specific to a borrower’s circumstances, the level of non-performing assets will fluctuate.

Compared to December 31, 2023, non-performing loans decreased $765,000 to $11.0 million at June 30, 2024. The majority of this decrease was in the non-performing commercial real estate loans category, which decreased $788,000 from December 31, 2023. Compared to March 31, 2024, non-performing loans decreased $10.3 million.

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

Activity in the non-performing loans categories during the quarter ended June 30, 2024, was as follows:

At June 30, 2024, the non-performing commercial real estate category included five loans, one of which was added during the current quarter. The largest relationship in the category, which totaled $7.2 million, or 73.5% of the total category, was added to non-performing loans during the second quarter of 2023 and is collateralized by an office building in Missouri. The balance of this relationship was reduced by payments of $700,000 during the three months ended June 30, 2024. Another loan, totaling $2.4 million, which was a purchased participation loan originally obtained through an FDIC-assisted acquisition, is collateralized by a low-income assisted living facility in Wisconsin. During the first quarter of 2024, the Company purchased the lead participant’s $220,000 interest in this note resulting in a 66% ownership interest. The other residential (multi-family) category of non-performing loans consisted of one student housing project in Texas, which was added to this category during the first quarter of 2024 and transferred to foreclosed assets during the three months ended June 30, 2024. The non-performing one- to four-family residential category included three loans. The largest relationship in the category totaled $593,000, or 51.7% of the category, and was added in the current quarter. The non-performing consumer category included five loans, one of which was added during the current quarter.

Potential problem loans decreased $1.8 million, to $5.6 million at June 30, 2024 from $7.4 million at December 31, 2023. Compared to March 31, 2024, potential problem loans also decreased $1.8 million. The decrease was primarily due to a $7.2 million loan in the other residential (multi-family) category that paid off during the three months ended June 30, 2024, partially offset by the addition of one loan relationship totaling $4.9 million ($4.4 million in the commercial real estate category and $498,000 in the consumer category) during the three months ended June 30, 2024.

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

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

Activity in foreclosed assets and repossessions during the quarter ended June 30, 2024 was as follows:

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

BUSINESS INITIATIVES

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

The system migration efforts were beset by a variety of significant issues, including having missed a second conversion date because of continued operational and system problems. Therefore, Great Southern has taken the following actions to protect its interests. On April 24, 2024, Great Southern informed the third-party vendor that it was terminating the Master Agreement between Great Southern and the third-party vendor in accordance with Great Southern’s rights under the Master Agreement. In addition, on April 24, 2024, Great Southern initiated legal action against the third-party vendor by filing a complaint in the U.S. District Court for the Western District of Missouri, Southern Division. The complaint seeks to recover damages caused by the third-party vendor’s material breach of the Master Agreement, inability and/or inaction on the part of the third-party vendor to effectively and timely manage the system migration, as well as the third-party vendor’s misrepresentations and omissions.

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

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”). This non-GAAP financial information includes the tangible common equity to tangible assets ratio.

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

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