Dear Shareholder,

The board of directors of First Bancshares, Inc. has declared a second-quarter dividend in the amount of thirty-five cents ($0.35) per share, consistent with the most recent quarterly payment made in April. This payment is enclosed or has been direct deposited for those that are electing cash payments. Additional shares of First Bancshares stock will be purchased for those that are part of the dividend reinvestment plan.

From the summary financial statistics worksheet included, Net Income for the first half of 2026 increased by $307.5k, or 60% compared to the same period in 2025. Interest & investment income improved by $669.5k year over year, primarily driven by a $967.5k increase in investment income, which remains very strong since our securities portfolio restructuring in Q3 2025. This was partially offset by a $230.9k decline in loan interest, as rates declined year over year. Loan balances were down by $6.5MM, but relatively stable compared to the previous quarter.

Fed Funds balances were up slightly, while rates were down 74 basis points year over year, resulting in $67k less income. The cost of deposits improved by $107.6k, due to an overall drop in rates of 12 basis points, while balances were up nearly $6MM year over year. The interest cost improvement on deposits was substantially offset by higher interest carrying cost of our subordinated debt of $100.9k, as this debt ($8MM) repriced from fixed to floating in Q1, which is currently higher than the original fixed rate.

While the bank did not add to its ACL Reserves in Q2, we continue to exercise appropriate risk management oversight for our loan portfolio. The portfolio continues to perform relatively well during these times of continued global instability. We will continue to closely monitor the impact of inflation on our markets, while maintaining sound underwriting practices for new opportunities.

Non-interest expenses for the quarter increased year over year, primarily driven by an increase in group insurance costs and personnel expenses. The bank added experienced sales staff over the past nine months as part of our strategic plan to grow the loan portfolio and profitability. The bank has shown positive early returns on the plan, as evidenced by the Per Share Data and Financial Ratios disclosed on the financial statistics worksheet included. First Bancshares also recovered $61.1k in federal income taxes from the net operating loss carry forward from 2025.

Proactive client and prospective client outreach within the communities we serve remains a top priority for our banking teams. While interest rates remain relatively stable, we are routinely reviewing our securities portfolio, so to protect our revenue streams from interest rate volatility should it occur.

On behalf of the board, we thank you for your support and look forward to continued success in 2026.

Sincerely,

Jeffery S. Bechtel-President & CEO

James V. Stouffer, Jr.- Chairman
