Bloomington, IL, January 26, 2026 – HBT Financial, Inc. (NASDAQ: HBT) (the “Company”, “HBT Financial” or “HBT”), the holding company for Heartland Bank and Trust Company, today reported net income of $18.9 million, or $0.60 diluted earnings per share, for the fourth quarter of 2025. This compares to net income of $19.8 million, or $0.63 diluted earnings per share, for the third quarter of 2025, and net income of $20.3 million, or $0.64 diluted earnings per share, for the fourth quarter of 2024.

J. Lance Carter, President and Chief Executive Officer of HBT Financial, said, “Our fourth quarter results wrapped up a very successful 2025, with adjusted net income(1) of $20.1 million, or $0.64 per diluted share, which was underpinned by strong balance sheet growth, excellent asset quality, and a resilient net interest margin. Loans increased $56.2 million, or 6.6% on an annualized basis, during the fourth quarter of 2025. Deposits also increased during the quarter despite moving $50.0 million of wealth management deposits off balance sheet due to strong liquidity. Asset quality remained strong with nonperforming assets to total assets remaining stable at 0.17% and charge-offs for the quarter remaining modest at 0.10%, on an annualized basis, and 0.07% for the full year.

Profitability remained strong during the fourth quarter of 2025, with an adjusted return on average assets(1) of 1.57% and an adjusted return on average tangible common equity(1) of 14.97%. In addition, tangible book value per share(1) increased to $17.20 at December 31, 2025, a 16.2% increase over the past year.

Looking ahead to 2026, we feel our strong liquidity, capital, and asset quality levels position us for another solid year of performance. We are excited about the proposed merger with CNB Bank Shares, Inc., which will be an attractive combination of our two franchises, materially enhancing our presence in the Chicago and St. Louis markets while also providing access to many new markets in central Illinois. We look forward to CNB Bank employees joining our team. The integration planning is progressing well, with anticipated closing and core system conversion expected to be completed in the first quarter of 2026.”

In addition to reporting GAAP results, the Company believes non-GAAP measures such as adjusted net income and adjusted earnings per share, which adjust for acquisition expenses, branch closure expenses, losses on extinguishment of debt, gains (losses) on closed branch premises, realized gains (losses) on sales of securities, mortgage servicing rights (“MSR”) fair value adjustments, and the tax effect of these pre-tax adjustments, provide investors with additional insight into its operational performance. The Company reported adjusted net income of $20.1 million, or $0.64 adjusted diluted earnings per share, for the fourth quarter of 2025. This compares to adjusted net income of $20.5 million, or $0.65 adjusted diluted earnings per share, for the third quarter of 2025, and adjusted net income of $19.5 million, or $0.62 adjusted diluted earnings per share, for the fourth quarter of 2024. See “Reconciliation of Non-GAAP Financial Measures” tables below for reconciliation of non-GAAP financial measures to their most closely comparable GAAP financial measures.

Net interest income for the fourth quarter of 2025 was $50.5 million, an increase of 1.1% from $50.0 million for the third quarter of 2025. The increase was primarily attributable to a decrease in funding costs and higher average interest-earning asset balances, which were partially offset by lower yields on loans as a result of decreases in benchmark interest rates. Additionally, a $0.3 million decrease in loan fees was partially offset by a $0.1 million increase in nonaccrual interest recoveries.

Relative to the fourth quarter of 2024, net interest income increased 6.6% from $47.4 million. The increase was primarily attributable to lower funding costs, higher average interest-earning asset balances, and improved yields on debt securities which were partially offset by a decrease in loan yields. Partially offsetting these improvements were a $0.2 million decrease in acquired loan discount accretion and a $0.1 million decrease in nonaccrual interest recoveries.

Net interest margin for the fourth quarter of 2025 was 4.12%, compared to 4.13% for the third quarter of 2025, while net interest margin (tax-equivalent basis)(1) for the fourth quarter of 2025 was 4.16%, compared to 4.18% for the third quarter of 2025. Lower yields on loans, which decreased 13 basis points to 6.22%, primarily driven by lower interest rates and a reduction in loan fees, were largely offset by higher average loan balances and lower funding costs, which decreased 6 basis points to 1.23%.

Relative to the fourth quarter of 2024, net interest margin increased 16 basis points from 3.96% and net interest margin (tax-equivalent basis)(1) increased 15 basis points from 4.01%. These increases were primarily attributable to lower funding costs and improved yields on debt securities, partially offset by a decrease in loan yields.

Noninterest income for the fourth quarter of 2025 was $9.9 million, a slight increase from $9.8 million for the third quarter of 2025. The increase was primarily attributable to a $0.2 million increase in wealth management fees, primarily driven by an increase in farm management fees and higher values of assets under management, as well as changes in the MSR fair value adjustment, with a $0.3 million negative MSR fair value adjustment included in the fourth quarter 2025 results compared to a $0.5 million negative MSR fair value adjustment included in the third quarter 2025 results. These improvements were mostly offset by a $0.2 million loss on the sale of foreclosed assets during the fourth quarter of 2025 compared to a $0.1 million gain during the third quarter 2025.

Relative to the fourth quarter of 2024, noninterest income decreased 14.9% from $11.6 million. The decrease was primarily attributable to changes in the MSR fair value adjustment, with a $0.3 million negative MSR fair value adjustment included in the fourth quarter 2025 results compared to a $1.3 million positive MSR fair value adjustment included in the fourth quarter 2024 results. Additionally, a $0.2 million decrease in income of bank owned life insurance, primarily attributable to the absence of a $0.2 million gain on life insurance proceeds recognized in the fourth quarter 2024 results, was mostly offset by higher wealth management fees.

Noninterest expense for the fourth quarter of 2025 was $33.1 million, a 1.7% increase from the third quarter of 2025. The increase was primarily attributable to $1.0 million of acquisition-related expenses included in the fourth quarter 2025 results. Excluding acquisition-related expenses, the $0.4 million decrease in noninterest expense was primarily attributable to the absence of a $0.4 million loss on extinguishment of debt included in the third quarter 2025 results associated with the early payoff of $40.0 million of subordinated notes. Additionally, a $0.4 million increase in data processing expense, primarily related to a planned call center software upgrade, was mostly offset by a $0.3 million decrease in other noninterest expense.

Relative to the fourth quarter of 2024, noninterest expense increased 7.0% from $30.9 million. Excluding acquisition-related expenses, the $1.2 million increase in noninterest expense was primarily attributable to higher salaries expense, driven by annual merit increases, and higher employee benefits expense, driven by higher medical benefit costs.

On October 20, 2025, HBT Financial and CNB Bank Shares, Inc. (“CNB”), the holding company for CNB Bank & Trust, N.A. (“CNB Bank”), jointly announced the signing of a definitive agreement pursuant to which HBT will acquire CNB and CNB Bank. The acquisition will further enhance HBT’s footprint in the central Illinois, the Chicago MSA and the St. Louis MSA markets. Acquisition-related expenses consisted of the following during the fourth quarter of 2025 (dollars in thousands):

Total loans outstanding, before allowance for credit losses, were $3.46 billion at December 31, 2025, compared with $3.40 billion at September 30, 2025, and $3.47 billion at December 31, 2024. The $56.2 million increase from September 30, 2025 was primarily attributable to new originations to existing customers within the construction and land development and multi-family segments, as well as higher line usage in our commercial and industrial portfolio. The higher line usage was driven in part by a $15.5 million seasonal increase in grain elevator line balances as well as $8.0 million drawn on two customers’ lines which were funded shortly before and paid off shortly after year-end.

Total deposits were $4.36 billion at December 31, 2025, compared with $4.35 billion at September 30, 2025, and $4.32 billion at December 31, 2024. The $12.1 million increase from September 30, 2025 was primarily attributable to higher balances maintained in retail and business accounts. These increases were partially offset by a $65.2 million reduction in wealth management customer money market deposits, of which $50.0 million was moved off-balance sheet during the fourth quarter due to strong levels of on-balance sheet liquidity, and lower balances maintained in public fund accounts.

Nonperforming assets totaled $8.7 million, or 0.17% of total assets, at December 31, 2025, compared with $8.6 million, or 0.17% of total assets, at September 30, 2025, and $8.0 million, or 0.16% of total assets, at December 31, 2024. Additionally, of the $7.6 million of nonperforming loans held as of December 31, 2025, $2.2 million were either wholly or partially guaranteed by the U.S. government.

The Company recorded a provision for credit losses of $1.5 million for the fourth quarter of 2025. The provision for credit losses primarily reflects a $2.2 million increase in required reserves driven by increased loan balances and changes within the portfolio; a $0.1 million increase in required reserves driven by changes in the economic forecast; and a $0.8 million decrease in specific reserves.

The Company had net charge-offs of $0.8 million, or 0.10% of average loans on an annualized basis, for the fourth quarter of 2025, compared to net charge-offs of $0.1 million, or 0.02% of average loans on an annualized basis, for the third quarter of 2025, and net charge-offs of $0.7 million, or 0.08% of average loans on an annualized basis, for the fourth quarter of 2024.

The Company’s allowance for credit losses was 1.21% of total loans and 552% of nonperforming loans at December 31, 2025, compared with 1.23% of total loans and 548% of nonperforming loans at September 30, 2025. In addition, the allowance for credit losses on unfunded lending-related commitments totaled $4.1 million as of December 31, 2025, compared with $3.3 million as of September 30, 2025.

As of December 31, 2025, the Company exceeded all regulatory capital requirements under Basel III as summarized in the following table:

The ratio of tangible common equity to tangible assets(1) increased to 10.82% as of December 31, 2025, from 10.56% as of September 30, 2025, and tangible book value per share(1) increased by $0.56 to $17.20 as of December 31, 2025, when compared to September 30, 2025.

During the fourth quarter of 2025, the Company repurchased 23,879 shares of its common stock at a weighted average price of $24.33 under its stock repurchase program. The Company’s Board of Directors authorized a new stock repurchase program that took effect upon the expiration of the Company’s prior stock repurchase program on January 1, 2026. The new stock repurchase program will be in effect until January 1, 2027 and authorizes the Company to repurchase up to $30.0 million of its common stock.
