------

***Securities***

The securities portfolio increased $3.3 million or 0.33%, from the linked quarter. This increase was impacted by $4.0 million in positive pre-tax fair value adjustments. The securities portfolio, based on estimated fair value, represented 12.04% of total assets as of Dec. 31, 2025.

***Borrowings***

Borrowings increased $56.5 million or 11.41%, from the linked quarter due primarily to increases in short-term Federal Home Loan Bank advances.

***Shareholders' Equity***

Shareholders' equity increased $18.4 million or 2.10% compared to the linked quarter. Accumulated other comprehensive income (AOCI) increased $3.1 million or 8.62%, during the quarter due to positive after-tax fair value adjustments in the securities portfolio.

------

Non-GAAP net interest income (excluding loan discount accretion of $1.4 million) totaled $69.4 million for the quarter ended Dec. 31, 2025, compared to $68.2 million (excluding loan discount accretion of $1.1 million) for the linked quarter. Non-GAAP net interest margin and net interest spread (excluding loan discount accretion of $1.4 million) were 3.64% and 2.84%, respectively, for the quarter ended Dec. 31, 2025, compared to 3.63% and 2.80% (excluding loan discount accretion of $1.1 million) for the linked quarter.

***Provision for Credit Losses***

During the quarter ended Dec. 31, 2025, Business First recorded a provision for credit losses of $3.1 million, compared to $3.2 million from the linked quarter. The current quarter's reserve was largely impacted by $6.8 million in net charge-offs and $168.4 million in loan growth, partially offset by qualitative adjustments. At Dec. 31, 2025, the ratio of allowance for credit losses to loans held for investment ratio was 0.94%, compared to 1.03% for the linked quarter.

***Other Income***

For the quarter ended Dec. 31, 2025, other income increased $0.6 million or 4.79%, compared to the linked quarter. The increase was largely attributable to growth of $0.7 million in swap fee income, $0.3 million in fee and brokerage commissions and $0.3 million in other income, partially offset by a loss on disposal other assets of $1.0 million. Excluding the $1.0 million loss on disposal of other assets related to branch closures during the fourth quarter, other income was $13.2 million compared to $11.6 million for the linked quarter, an increase of $1.6 million, or 13.77%.

***Other Expenses***

For the quarter ended Dec. 31, 2025, other expenses increased $3.5 million or 7.22% compared to the linked quarter. The increase was largely attributable to a $2.8 million increase in salaries and employee benefits. Salaries and benefits were impacted favorably during the third quarter due to a one-time $2.0 million tax credit refund. Excluding merger-related, core conversion expenses and tax refunds recognized in the current and linked quarters, other expenses were $50.2 million compared to $49.3 million for the linked quarter, an increase of $0.9 million, or 1.88%.

***Return on Assets and Common Equity***

Return to common shareholders on average assets and common equity, each on an annualized basis, were 1.04% and 10.18% for the quarter ended Dec. 31, 2025, compared to 1.08% and 10.80%, respectively, for the linked quarter.

**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.

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.
