**Statement of Financial Condition**

***Loans***

Loans held for investment decreased $26.6 million or 0.44%, 1.74% annualized. The commercial and commercial real estate portfolios decreased $40.2 million and $71.1 million, respectively, compared to the linked quarter. The construction and residential portfolios increased $38.6 million and $47.6 million compared to the linked quarter. Texas-based loans represented approximately 40% of the overall loan portfolio as of Sept. 30, 2025, based on unpaid principal balance.

***Credit Quality***

Credit quality metrics stabilized compared to the prior quarter. The ratio of loans past due 30 days or more, excluding nonaccrual, compared to total loans held for investment decreased from 0.89% to 0.27% at Sept. 30, 2025. The ratio of nonperforming loans compared to loans held for investment decreased 15 basis points (bps) to 0.82% at Sept. 30, 2025, while the ratio of nonperforming assets compared to total assets increased 7 bps to 0.83% compared to the linked quarter. The increase in the nonperforming assets ratio over the linked quarter was attributable to the transfer of some nonaccrual loans to other real estate owned. The commercial, residential real estate, commercial real estate and construction portfolios encompass approximately $21.9 million, $10.2 million, $9.0 million and $4.0 million respectively, of the $45.4 million nonaccrual balance at Sept. 30, 2025.

***Securities***

The securities portfolio increased $59.5 million, or 6.42%, from the linked quarter. This increase was impacted by $14.4 million in positive pre-tax fair value adjustments and the remainder attributed largely to purchases of mortgage-backed securities. The securities portfolio, based on estimated fair value, represented 12.40% of total assets as of Sept. 30, 2025. The newly purchased securities increased the book yield of the securities portfolio from 2.77% to 2.92% at Sept. 30, 2025.

***Deposits***

Deposits increased $87.2 million or 1.36%, 5.39% annualized, for the quarter ended Sept. 30, 2025, compared to the linked quarter. Average interest-bearing deposits increased $92.2 million, or 1.83%, and noninterest-bearing deposits increased $22.8 million or 1.76%, from the linked quarter.

**b1BANK.com**

------

Period-end interest bearing deposits increased $131.4 million or 2.62% and noninterest bearing deposits decreased $44.2 million or 3.13%. The increase in interest-bearing deposits was largely attributed to money market accounts, which experienced rate reductions of approximately 25 bps towards the end of the quarter.

***Borrowings***

Borrowings decreased $118.3 million or 19.29%, from the linked quarter due primarily to reductions in short-term Federal Home Loan Bank advances.

***Shareholders' Equity***

Shareholders' equity increased $30.0 million or 3.54% compared to the linked quarter. Accumulated other comprehensive income (AOCI) increased $11.3 million or 23.74%, during the quarter due to positive after-tax fair value adjustments in the securities portfolio. Book value per common share increased to $27.23 at Sept. 30, 2025, compared to $26.23 at June 30, 2025, due to strong earnings and positive fair value adjustments in the securities portfolio. On a non-GAAP basis, tangible book value per common share increased from $21.61 at the linked quarter to $22.63 at Sept. 30, 2025, 4.75% or 18.83% annualized.

For the quarter ended Sept. 30, 2025, net interest income totaled $69.3 million, compared to $67.0 million from the linked quarter. Loan yields increased 5 bps to 7.01% compared to 6.96% from the linked quarter, while the interest-bearing asset yield remained flat at 6.31%. Net interest margin and net interest spread were 3.68% and 2.85% compared to 3.68% and 2.88% for the linked quarter. The overall cost of funds, which included noninterest-bearing deposits, increased 3 bps from 2.78% to 2.81% for the quarter ended Sept. 30, 2025.

**b1BANK.com**

------

Non-GAAP net interest income (excluding loan discount accretion of $1.1 million) totaled $68.2 million for the quarter ended Sept. 30, 2025, compared to $66.3 million (excluding loan discount accretion of $0.8 million) for the linked quarter. Non-GAAP net interest margin and net interest spread (excluding loan discount accretion of $1.1 million) were 3.63% and 2.80%, respectively, for the quarter ended Sept. 30, 2025, compared to 3.64% and 2.84% (excluding loan discount accretion of $0.8 million) for the linked quarter.

***Provision for Credit Losses***

During the quarter ended Sept. 30, 2025, Business First recorded a provision for credit losses of $3.2 million, compared to $2.2 million from the linked quarter. The current quarter's reserve was largely impacted by an additional $1.5 million reserve on unfunded loan commitments and the remainder attributed to reserves on individually evaluated loans. At Sept. 30, 2025, the ratio of allowance for credit losses to loans held for investment ratio was 1.03%, compared to 1.02% for the linked quarter.

***Other Income***

For the quarter ended Sept. 30, 2025, other income decreased $2.7 million or 19.04%, compared to the linked quarter. The decrease was largely attributable to a $3.4 million gain on the Kaplan branch sale in the linked quarter, positively offset by a $414,000 increase related to other real estate owned and a $379,000 increase in equity investment income. Excluding the gain on the Kaplan branch sale and securities sale gains and losses, other income for Sept. 30, 2025, was $11.6 million compared to $11.1 million for the linked quarter, an increase of $492,000, or 4.43%.

***Other Expenses***

For the quarter ended Sept. 30, 2025, other expenses decreased $2.3 million or 4.54% compared to the linked quarter. The decrease was largely attributable to a $1.9 million tax credit the company recognized as an expense reduction within salaries and employee benefits. Excluding the tax credit recognized in the current quarter and merger-related and core conversion expenses recognized in both the current and linked quarters, other expenses were $49.3 million compared to $49.6 million for the linked quarter, a decrease of $345,000 or 0.70%.

**Non-GAAP Financial Measures**

This press release includes certain non-GAAP financial measures (e.g., referenced as "core" or "tangible") intended to supplement, not substitute for, comparable GAAP measures. "Core" measures typically adjust income available to common shareholders for certain significant activities or transactions that, in management's opinion, can distort period-to-period comparisons of Business First's performance. Transactions that are typically excluded from non-GAAP "core" measures include realized and unrealized gains/losses on former bank premises and equipment, investment sales, acquisition-related expenses (including, but not limited to, legal costs, system conversion costs, severance and retention payments, etc.). "Tangible" measures adjust common equity by subtracting goodwill, core deposit intangibles, and customer intangibles, net of accumulated amortization. Management believes presentations of these non-GAAP financial measures provide useful supplemental information that is essential to a proper

understanding of the operating results of Business First's core business. These non-GAAP disclosures are not necessarily comparable to non-GAAP measures that may be presented by other companies. Reconciliations of non-GAAP financial measures to GAAP financial measures are provided at the end of the tables below.

3 LEGAL DISCLOSURES Special Note Concerning Forward-Looking Statements This investor presentation contains "forward-looking statements" within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking statements. You can identify these forward-looking statements in some cases through the Company's use of words such as "believes," "anticipates," "expects," "may," "will," "assumes," "should," "predicts," "could," "would," "intends," "targets," "estimates," "projects," "plans," "potential" and other similar words and expressions of the future or otherwise regarding the Company's future business and financial performance and/or the performance of the banking and mortgage industry and economy in general. Forward-looking statements are based on the information known to, and current beliefs and expectations of, the Company's management and are subject to significant risks and uncertainties. Actual results may differ materially from those contemplated by such forward-looking statements. A number of important factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this presentation including, without limitation, the risks set forth in "Forward Looking Statements" and "Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 7, 2025 (as may be amended in the Company's Quarterly Reports on Form 10-Q). Many of these factors are difficult to foresee and are beyond the Company's ability to control or predict. The Company believes the forward-looking statements contained herein are reasonable; however, undue reliance should not be placed on any forward-looking statements, which are based on current expectations and speak only as of the date that they are made. The Company does not assume any obligation to update any forward-looking statements as a result of new information, future developments or otherwise, except as otherwise may be required by law. Non-GAAP Financial Measures This presentation includes certain financial measures that are not measures recognized under U.S. generally accepted accounting principles ("GAAP") and therefore are considered non-GAAP financial measures. The Company's management uses these non-GAAP financial measures in their analysis of the Company's performance, financial condition and the efficiency of its operations. Management believes that these non-GAAP financial measures provide a greater understanding of the ongoing operations and enhance comparability of results with prior periods. The Company's management also believes that investors find these non-GAAP financial measures useful as they assist investors in understanding the Company's underlying operating performance and the analysis of ongoing operating trends. However, the non-GAAP financial measures discussed herein should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which the Company calculates the non-GAAP financial measures discussed herein may differ from the reporting measures with similar names as used by other companies. You should understand how such other banking organizations calculate their non-GAAP financial measures with names similar to the non-GAAP financial measures discussed herein when comparing such information. Reconciliations of non-GAAP financial measures to GAAP financial measures are provided in the Appendix to this presentation.

HFS) / Deposits 92.53 % 94.21 % 92.54 % Decrease for the quarter was driven primarily by interest-bearing deposit growth of $131.4 million during Q3 Borrowings decreased $118.3 million for the quarter due primarily to reductions in short-term FHLB advances. Increase in equity for the quarter of $30.0 million driven by positive quarterly earnings coupled with positive after-tax fair value adjustments. Highlights Increase in tangible common equity for the quarter of $30.6 million driven by positive quarterly earnings. TBV increased by $1.03 or 4.75% (18.83% annualized) from the linked quarter and is attributed to $21.5 million net income available to common shareholders. The improvement in the risk-based capital ratio was attributable to the retention of earnings coupled with stability of risk-based assets in 3Q25. Actual Change vs. Q3'25 Highlights Loan balances decreased $26.6 million, or 0.44% for the quarter (1.74% annualized) driven by decreases in Commercial ($40.2 million) and Commercial Real Estate ($71.1 million). Our Texas exposure represented approximately 40% of the overall loan portfolio. Deposits increased $87.2 million (1.36%, or 5.39% annualized) during Q3 as interest-bearing deposits increased $131.4 million (2.62%) and noninterest-bearing deposits decreased $44.2 million (3.13%). ACL + Fair Value Discount on acquired loans as a percentage of total loans of 1.17%. Loan purchase discount decreased by approximately $1.2 million. The $59.5 million increase for the quarter stemmed from positive fair market value adjustments ($14.4 million) with the remainder primarily attributed to purchases of mortgage-backed securities.
