Great Southern Bancorp, Inc. Reports Preliminary Third Quarter Earnings of $1.56 Per Diluted Common Share

Preliminary Financial Results and Business Update for the Quarter Ended September 30, 2025

SPRINGFIELD, Mo., Oct. 15, 2025 (GLOBE NEWSWIRE) -- Great Southern Bancorp, Inc. (the “Company”) (NASDAQ:GSBC), the holding company for Great Southern Bank (the “Bank”), today reported that preliminary earnings for the three months ended September 30, 2025, were $1.56 per diluted common share ($17.8 million net income) compared to $1.41 per diluted common share ($16.5 million net income) for the three months ended September 30, 2024.

For the quarter ended September 30, 2025, annualized return on average common equity was 11.30%, annualized return on average assets was 1.23%, and annualized net interest margin was 3.72%, compared to 11.10%, 1.11% and 3.42%, respectively, for the quarter ended September 30, 2024.

Third Quarter 2025 Key Results:

- Net Interest Income: Net interest income for the third quarter of 2025 increased $2.8 million (or approximately 5.8%) to $50.8 million compared to $48.0 million for the third quarter of 2024, largely driven by lower interest expense on deposit accounts and other borrowings. Annualized net interest margin was 3.72% for the quarter ended September 30, 2025, compared to 3.42% for the quarter ended September 30, 2024, and 3.68% for the quarter ended June 30, 2025. On October 6, 2025, interest income from the Company’s terminated interest rate swap ceased, which had been providing approximately $2.0 million of interest income per quarter through the third quarter of 2025.
- Asset Quality: Non-performing assets and potential problem loans totaled $9.2 million at September 30, 2025, a decrease of $7.4 million from $16.6 million at December 31, 2024. At September 30, 2025, non-performing assets were $7.8 million (0.14% of total assets), a decrease of $1.8 million from $9.6 million (0.16% of total assets) at December 31, 2024. See “Asset Quality” below.
- Liquidity: The Company had secured borrowing line availability at the FHLBank and Federal Reserve Bank of $1.11 billion and $356.2 million, respectively, at September 30, 2025. In addition, at September 30, 2025, the Company had unpledged securities with a market value totaling $369.9 million, which could be pledged as collateral for additional borrowing capacity at either the FHLBank or Federal Reserve Bank.
- Capital: The Company’s capital position remained strong as of September 30, 2025, significantly exceeding the thresholds established by regulators. On a preliminary basis, as of September 30, 2025, the Company’s Tier 1 Leverage Ratio was 11.9%, Common Equity Tier 1 Capital Ratio was 13.3%, Tier 1 Capital Ratio was 13.8%, and Total Capital Ratio was 15.1%. The Company’s tangible common equity to tangible assets ratio was 10.9% at September 30, 2025. See “Capital” below.
- Loans: Total net loans, excluding mortgage loans held for sale, decreased $222.7 million, or 4.7%, from $4.69 billion at December 31, 2024 to $4.47 billion at September 30, 2025. This decrease was primarily driven by decreases in construction loans, other residential (multi-family) loans, and one- to four-family residential loans. Compared to June 30, 2025, net loans decreased $66.6 million.

Joseph W. Turner, President and CEO of Great Southern, commented, “Our third quarter results reflect continued stability in our core operations and disciplined execution of our long-term strategy to sustain profitability, protect credit quality, and enhance shareholder value. Core performance remained solid, with consistent net interest income, strong asset quality, and prudent expense management despite a continued competitive funding environment. We reported net income of $17.8 million, or $1.56 per diluted common share, for the third quarter of 2025, compared to $16.5 million, or $1.41 per diluted common share, in the same period last year.”

Turner noted, “Despite continued economic pressures, our core operations have been strong. Total interest income for the third quarter of 2025 was $79.1 million, reflecting only modest decreases in interest income and yields on loans and investment securities, despite reductions in market interest rates since the third quarter of 2024. Net interest income for the quarter increased to $50.8 million compared to $48.0 million in the same quarter last year, demonstrating the continued resilience of our margin and disciplined asset-liability management in a highly competitive deposit market. However, as we’ve noted previously, we will no longer have the benefit of interest income from the terminated swap in future periods. The funding costs of deposits and other borrowings continued to decrease, bolstering net interest income. Core deposits remained stable during the quarter, underscoring the strength of our customer relationships and the enduring value of our community banking franchise. We continue to manage deposit and other funding costs carefully, maintaining pricing discipline while also ensuring flexibility amidst a volatile interest rate environment.”

Turner added, “Our balance sheet remains well-positioned, with total assets of approximately $5.74 billion at September 30, 2025, reflecting modest contraction due to elevated net loan payoffs during the quarter and throughout much of 2025. Total net loans declined by approximately $222.7 million from the year-end 2024 balance, largely due to multi-family loan and construction loan pay-downs, consistent with renewed refinancing and capital markets activity. Credit quality remains a key strength, with low levels of non-performing assets and no provision expense recorded this quarter or year to date on the portfolio of outstanding loan balances, reflecting the soundness of our underwriting and portfolio management practices.”

Turner further noted, “On the expense side, operating discipline remains a primary focus. Non-interest expense for the third quarter totaled approximately $36.1 million, modestly above recent quarters, driven by higher legal and professional fees and upgrades of the Bank’s core technology systems. Non-interest income totaled $7.1 million for the third quarter of 2025, supported by loan, deposit, and debit card service fee income and other recurring revenue sources.”
Turner continued, “Looking ahead, our priorities remain unchanged: maintaining strong capital and liquidity positions, supporting our customers, and continuing to generate value for our shareholders. At September 30, 2025, the tangible common equity ratio was 10.9% and book value per common share was approximately $56.18 per share, reflecting the benefit of consistent earnings and opportunistic share repurchases. In the third quarter of 2025, we repurchased roughly 165,000 shares of our common stock, underscoring our continued commitment to long-term tangible book value per share growth.”

“Great Southern’s third-quarter 2025 results underscore the durability of our franchise and the consistency of our performance across economic cycles. We remain confident in our disciplined approach, sound balance sheet, and dedicated associates, all of which position us to deliver value for our customers, communities and shareholders,” Turner concluded.

NET INTEREST INCOME

| Three Months Ended
|  | September 30, |  |  | September 30, |  | June 30,
|  | 2025 |  |  | 2024 |  | 2025
|  | (Dollars in thousands)
Interest Income | $ | 79,079 |  |  | $ | 83,796 |  |  | $ | 80,975 |
Interest Expense |  | 28,306 |  |  |  | 35,821 |  |  |  | 30,012 |
Net Interest Income | $ | 50,773 |  |  | $ | 47,975 |  |  | $ | 50,963 |
Net interest margin |  | 3.72 | % |  |  | 3.42 | % |  |  | 3.68 | %
Average interest-earning assets to average interest-bearing liabilities |  | 128.1 | % |  |  | 126.8 | % |  |  | 126.9 | %

Net interest income for the third quarter of 2025 increased $2.8 million (5.8%) to $50.8 million, compared to $48.0 million for the third quarter of 2024. This increase in net interest income was driven primarily by the strategic management of maturing/repricing brokered deposits and interest-bearing demand deposits to reduce interest expense. Also, there was no interest expense on subordinated notes in the quarter ended September 30, 2025, as those notes were redeemed in June 2025. These interest expense reductions were partially offset by a reduction in interest income on loans due to lower balances and lower market rates, which impacted the interest rate on variable-rate loans. Annualized net interest margin was 3.72% in the third quarter of 2025, compared to 3.42% in the same period of 2024 and 3.68% in the second quarter of 2025. The average interest rate spread was 3.13% for the three months ended September 30, 2025, compared to 2.74% for the three months ended September 30, 2024 and 3.09% for the three months ended June 30, 2025.

The average yield on total interest-earning assets decreased from 5.98% in the 2024 third quarter to 5.79% in the 2025 third quarter, with the average yield on loans decreasing 23 basis points, the average yield on investment securities increasing 15 basis points and the average yield on other interest earning assets (primarily funds held at the Federal Reserve Bank) decreasing 113 basis points. The average rate paid on total interest-bearing liabilities decreased from 3.24% in the 2024 third quarter to 2.66% in the 2025 third quarter, with the average rate paid on interest-bearing demand and savings deposits, time deposits and brokered deposits decreasing 34 basis points, 68 basis points and 72 basis points, respectively.

Market interest rates, primarily the federal funds rate and SOFR rates, declined in the fourth quarter of 2024, and remained lower through the third quarter of 2025, with an additional federal funds rate cut in September 2025. This market rate decline had a muted impact on the average yield on loans, as cash flows from lower-rate fixed rate loans were deployed into loans with comparably higher rates of interest. The decline in market interest rates also resulted in lower average rates paid on deposits and borrowings, compared to the prior-year third quarter.

To mitigate exposure to the risk of fluctuations in future cash flows resulting from changes in interest rates (primarily related to falling interest rates), the Company has strategically utilized derivative financial instruments - primarily interest rate swaps - as part of its interest rate risk management strategy.

The following table presents, for the periods indicated, the effect of cash flow hedge accounting included in interest income in the consolidated statements of income:

| Three Months Ended
|  | September 30, |  |  | September 30, |  | June 30,
|  | 2025 |  |  | 2024 |  | 2025
|  | (In thousands)
Terminated interest rate swaps | $ | 2,047 |  |  | $ | 2,047 |  |  | $ | 2,025 |
Active interest rate swaps |  | (1,761 | ) |  |  | (2,743 | ) |  |  | (1,757 | )
Increase (decrease) to interest income | $ | 286 |  |  | $ | (696 | ) |  | $ | 268 |

The Company entered into an interest rate swap in October 2018, which was terminated in March 2020. Upon termination, the Company received $45.9 million, inclusive of accrued but unpaid interest, from its swap counterparty. The net amount, after deducting accrued interest and deferred income taxes, was accreted to interest income on loans monthly until the originally scheduled termination date of October 6, 2025. With this date having passed, the Company no longer has the benefit of that income from the terminated swap.

The cost of deposits has been negatively impacted 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. After the second quarter of 2023, the Company had a significant amount of time deposits maturing at relatively low interest rates. These deposits were either renewed at higher rates or withdrawn, requiring the Company to replace the withdrawn deposits with other funding sources at then-current market rates. Market rates for time deposits for much of 2024 remained elevated, but have declined as the FOMC cut the federal funds rate by 100 basis points in late 2024, 25 basis points in the third quarter of 2025 and signaled that further rate cuts may occur in the fourth quarter of 2025. As of September 30, 2025, time deposit maturities over the next 12 months were as follows: within three months — $675 million, with a weighted-average rate of 3.97%; within three to six months — $365 million, with a weighted-average rate of 3.29%; and within six to twelve months — $54 million, with a weighted-average rate of 2.16%. Based on time deposit market rates in September 2025, replacement rates for these maturing time deposits are likely to be approximately 3.10-3.60%, depending on term.

NON-INTEREST INCOME

For the quarter ended September 30, 2025, non-interest income increased $70,000 to $7.1 million when compared to the quarter ended September 30, 2024. The largest individual change in the various non-interest income categories in comparing the two periods was an increase of $206,000 in commission income.

NON-INTEREST EXPENSE

For the quarter ended September 30, 2025, non-interest expense increased $2.4 million to $36.1 million when compared to the quarter ended September 30, 2024, primarily as a result of the following items:

- Net occupancy and equipment expenses: Net occupancy and equipment expenses increased $735,000, or 9.0%, from the prior-year quarter. Various components of computer license and support expenses, related to upgrades of core systems capabilities and disaster recovery site, collectively increased by $637,000 in the third quarter of 2025 compared to the third quarter of 2024.
- Salaries and employee benefits: Salaries and employee benefits increased $636,000, or 3.3%, from the prior-year quarter. Much of this increase related to annual merit increases in various lending and operations areas.
- Legal, audit and other professional fees: Legal, audit and other professional fees increased $439,000 from the prior-year quarter, to $1.2 million. Of this total, legal fees increased $355,000 compared to the prior year period. In the quarter ended September 30, 2025, the Company incurred increased legal expenses related to certain corporate matters along with loan collection activities.
- Expense on other real estate owned: Expenses on other real estate owned increased $394,000, or 73.5%, from the prior-year quarter. In the quarter ended September 30, 2024, the Company recorded gains on sales of other real estate owned totaling $452,000, with no such gains in the 2025 period. In the quarter ended September 30, 2025, the Company recorded a total of $133,000 in rental income in excess of expense from other real estate owned, compared to $76,000 in the quarter ended September 30, 2024. The increase in rental income in the 2025 period related to the $6.0 million office building that was added to other real estate owned in the fourth quarter of 2024. See “Asset Quality” below.

The Company’s efficiency ratio for the quarter ended September 30, 2025, was 62.45% compared to 61.34% for the same quarter in 2024. The Company’s ratio of non-interest expense to average assets was 2.50% for the three months ended September 30, 2025, compared to 2.27% for the three months ended September 30, 2024. Average assets for the three months ended September 30, 2025, decreased $185.3 million, or 3.1%, compared to the three months ended September 30, 2024, primarily due to the decline in the average balance of net loans.

INCOME TAXES

For the three months ended September 30, 2025 and 2024, the Company's effective tax rate was 19.7% and 18.0%, respectively. For the nine months ended September 30, 2025 and 2024, the Company's effective tax rate was 19.4% and 18.5%, respectively. These effective rates were below the statutory federal tax rate of 21.0%, 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 currently expects its effective tax rate (combined federal and state) will be approximately 18.5% to 20.0% in future periods.

CAPITAL

| 2025 |  | 2024 |  | 2025
Consolidated Regulatory Capital Ratios | (Preliminary) |  |  |  |  |  |
Tier 1 Leverage Ratio | 11.9 | % |  | 11.2 | % |  | 11.5 | %

Tangible Common Equity Ratio | 10.9 | % |  | 9.9 | % |  | 10.5 | %

As of September 30, 2025, total stockholders’ equity was $632.9 million, representing 11.0% of total assets and a book value of $56.18 per common share. This compares to total stockholders’ equity of $599.6 million, or 10.0% of total assets, and a book value of $51.14 per common share at December 31, 2024. The $33.4 million increase in stockholders’ equity from December 31, 2024, was primarily driven by $54.7 million in net income, a decrease in unrealized losses and a $4.2 million increase from stock option exercises, partially offset by $14.0 million in cash dividends declared on the Company’s common stock and $30.0 million in common stock repurchases. The decreased unrealized losses on the Company’s available-for-sale investment securities and interest rate swaps, which totaled $35.9 million and $54.4 million (net of taxes) at September 30, 2025 and December 31, 2024, respectively, increased stockholders’ equity by $18.5 million during the first nine months of 2025. These net unrealized losses primarily resulted from increased intermediate-term market interest rates in prior periods, which generally decreased the fair value of the investment securities and interest rate swaps. In the first nine months of 2025, these market interest rates decreased, resulting in increases in the fair value of the Company’s investment securities and interest rate swaps.

The Company had unrealized losses on its portfolio of held-to-maturity investment securities, which totaled $17.7 million and $24.7 million at September 30, 2025 and December 31, 2024, respectively, that were not included in its total capital balance. If held-to-maturity unrealized losses were included in capital (net of taxes) at September 30, 2025 and December 31, 2024, they would have decreased total stockholder’s equity at those dates by $13.4 million and $18.6 million, respectively. These amounts were equal to 2.1% of total stockholders’ equity of $632.9 million at September 30, 2025, compared to 3.1% of total stockholders’ equity of $599.6 million at December 31, 2024.

In April 2025, the Company’s Board of Directors approved a new stock repurchase program, which succeeded the previous repurchase program (authorized in November 2022) following the repurchase of that program’s remaining available shares. The November 2022 stock repurchase program was completed during the third quarter of 2025. The stock repurchase program approved in April 2025 authorizes the purchase, from time to time, of up to one million additional shares of the Company’s common stock. As of September 30, 2025, approximately 929,000 shares remained available under this stock repurchase authorization.

During the three months ended September 30, 2025, the Company repurchased 165,116 shares of its common stock at an average price of $60.33, and the Company’s Board of Directors declared a regular quarterly cash dividend of $0.43 per common share, which, combined, reduced stockholders’ equity by $14.9 million.

During the nine months ended September 30, 2025, the Company repurchased 514,458 shares of its common stock at an average price of $57.89, and the Company’s Board of Directors declared regular quarterly cash dividends totaling $1.23 per common share, which, combined, reduced stockholders’ equity by $44.1 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. 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, at management’s discretion, supplements deposits with alternative sources of funds. Management believes that the Company maintains overall liquidity sufficient to satisfy its depositors’ requirements and meet its borrowers’ credit needs.

At September 30, 2025, the Company had the following available secured lines and on-balance sheet liquidity:

| September 30, 2025
Federal Home Loan Bank line | $1,111.0 million
Federal Reserve Bank line | 356.2 million
Cash and cash equivalents | 196.2 million
Unpledged securities – Available-for-sale | 344.3 million
Unpledged securities – Held-to-maturity | 25.6 million

During the nine months ended September 30, 2025, the Company’s total deposits decreased $77.5 million. Interest-bearing checking balances increased $54.3 million (2.4%), primarily in certain money market accounts, and non-interest-bearing checking balances increased $12.4 million (1.5%). Time deposits generated through the Company’s banking center and corporate services networks decreased $52.1 million (6.7%). Brokered deposits, obtained through a variety of sources, decreased $92.1 million (11.9%). During the three months ended September 30, 2025, the Company’s total deposits decreased $156.1 million, $153.3 million of which was in brokered deposits. As total assets (primarily loans receivable) decreased, the Company elected not to replace some of its maturing brokered deposits.

At September 30, 2025, the Company had the following deposit balances:

| September 30, 2025
Interest-bearing checking | $2,269.0 million
Non-interest-bearing checking | 855.4 million
Time deposits | 723.7 million
Brokered deposits | 680.0 million

At September 30, 2025, the Company estimated that its uninsured deposits, excluding deposit accounts of the Company’s consolidated subsidiaries, were approximately $741.9 million (16.4% of total deposits).

LOANS

Total net loans, excluding mortgage loans held for sale, decreased $222.7 million, or 4.7%, from $4.69 billion at December 31, 2024 to $4.47 billion at September 30, 2025. This decrease was primarily driven by decreases in construction loans of $122.7 million, other residential (multi-family) loans of $63.7 million, one- to four-family residential loans of $36.6 million and commercial real estate loans of $12.8 million. Compared to June 30, 2025, net loans decreased $66.6 million.

The pipeline of the unfunded portion of loans and formal loan commitments remained strong, with the largest portion of these unfunded balances represented by the unfunded portion of outstanding construction loans ($582.4 million at September 30, 2025). See the table below.

PROVISION FOR CREDIT LOSSES AND ALLOWANCE FOR CREDIT LOSSES

During the three months ended September 30, 2025, the Company did not record a provision expense on its portfolio of outstanding loans, compared to a provision expense of $1.2 million in the same period in 2024. During the nine months ended September 30, 2025, the Company did not record a provision expense on its portfolio of outstanding loans, compared to a provision expense of $1.7 million in the same period in 2024. Total net charge-offs were $66,000 for the three months ended September 30, 2025, compared to total net charge-offs of $1.5 million during the same period in the prior year. Total net charge-offs were $11,000 for the nine months ended September 30, 2025, compared to total net charge-offs of $1.5 million during the same period in the prior year. Additionally, for the quarter ended September 30, 2025, the Company recorded a negative provision for losses on unfunded commitments of $379,000, compared to a negative provision of $63,000 for the same period in 2024. For the nine months ended September 30, 2025, the Company recorded a negative provision for losses on unfunded commitments of $837,000, compared to a negative provision of $540,000 for the same period in 2024.

The Bank’s allowance for credit losses as a percentage of total loans was 1.43%, 1.36% and 1.41% at September 30, 2025, December 31, 2024 and June 30, 2025, respectively. Management considers the allowance for credit losses adequate to cover losses inherent in the Bank’s loan portfolio at September 30, 2025, based on recent reviews of the portfolio and current economic conditions. However, if challenging economic conditions persist or worsen, or if management’s assessment of the loan portfolio changes, additional provisions for credit losses may be required, which could adversely impact the Company’s future financial performance.

NON-GAAP FINANCIAL MEASURES

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

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

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