Business First Bancshares, Inc., Announces Financial Results for Q1 2026

Baton Rouge, La. (April 27, 2026) – Business First Bancshares, Inc. (NASDAQ: BFST) (Business First), parent company of b1BANK, today announced its unaudited results for the quarter ended March 31, 2026. Business First reported net income available to common shareholders of $22.2 million or $0.68 per diluted common share, an increase of $1.2 million and a decrease of $0.03, respectively, compared to the linked quarter. On a non-GAAP basis, core net income for the quarter ended March 31, 2026, which excludes certain income and expenses, was $24.0 million or $0.73 per diluted common share, an increase of $0.5 million and a decrease of $0.06 from the linked quarter. The quarter ended March 31, 2026, included the consummation of the Progressive Bancorp, Inc. (Progressive) acquisition.

“It was a busy and productive start of the year for b1BANK,” said Jude Melville, chairman, president, and CEO of Business First. “Quantitatively, we continued generating consistent profitability, increased our capital ratios and strengthened our liquidity positioning. Qualitatively, we added a large number of strong teammates through consummation of the Progressive Bank acquisition, the addition of a number of seasoned, respected bankers in Houston, and our partnership with Covecta, with whom we are working on building out Agentic AI capabilities. I’m also proud of our team’s self-managed subordinated-debt issuance through our network of community bank partners. All these deepening partnerships bode well for the continued building of shareholder value over the course of 2026.”

On Thursday, April 23, 2026, Business First’s board of directors declared a quarterly preferred dividend in the amount of $18.75 per share, which is the full quarterly dividend of 1.875% based on the per annum rate of 7.50%. Additionally, the board of directors declared a quarterly common dividend based upon financial performance for the first quarter in the amount of $0.15 per share of common stock. The preferred and common dividends will be paid on May 29, 2026, or as soon thereafter as practicable, to the shareholders of record as of May 15, 2026.

Quarterly Highlights

• Consistent Core Performance. Return to common shareholders on average assets, on an annualized basis, was 1.01% for the quarter ended March 31, 2026, or 1.10% on a non-GAAP basis, compared to 1.04% or 1.16% on a non-GAAP basis for the linked quarter.

• Progressive Acquisition. On January 1, 2026, Business First closed its previously announced acquisition of Progressive and its wholly-owned subsidiary, Progressive Bank. Progressive had approximately $773.8 million of total assets, $589.7 million of net loans, and $684.9 million of deposits as of December 31, 2025. Business First does not anticipate material synergies to be reflected in its earnings until after conversion in the third quarter. b1BANK added nine banking centers in North Louisiana as a result of the Progressive acquisition.

• Meaningful Production Additions. On January 15, 2026, Business First announced the hiring of a new regional president to the Houston, Texas market and head of private banking. This individual joined b1BANK from Veritex Community Bank, where he served as senior vice president and Houston market president. Prior to his tenure at Veritex, he had been with Comerica Bank for nearly 20 years in leadership roles across private banking, middle market, and wealth management. By quarter-end, we successfully added four producers and three production support staff to the new Houston team.

• New Technology Partnership. On February 17, 2026, b1BANK and Covecta announced a strategic partnership to deploy agentic AI across the bank’s day to day workflows. The collaboration focuses on streamlining and automating repeatable, policy-driven activities across core deposit and loan operational processes, reducing manual effort and operational friction so that teams can devote more time towards higher value-adding work including analysis, exception handling and customer engagement.

• Improving Shareholder Value. During the first quarter, as part of a previously announced stock repurchase program, Business First repurchased 99,105 shares, with a market value of $2.7 million, at a weighted average price of $27.75 per share. Common equity to total assets increased from 10.04% to 10.32%. Tangible common equity to tangible assets increased from 8.53% to 8.65%, 1.37% or 5.57% annualized, compared to the linked quarter. Book value per common share increased to $28.18 at March 31, 2026, compared to $27.95 at Dec. 31, 2025. On a non-GAAP basis, tangible book value per common share decreased from $23.36 at the link
