Share Purchase Agreement

On November 14, 2025, FB Financial Corporation (the “Company”) entered into a share purchase agreement with the Estate of James W. Ayers (the “Selling Shareholder”) and certain institutional investors (the “Purchasers”) pursuant to which the Selling Shareholder agreed to sell to the Purchasers, and the Purchasers agreed to purchase from the Selling Shareholder, in a registered direct offering, 2,162,052 shares of the Company’s common stock, par value $1.00 per share (the “Common Stock”), at a purchase price of $51.50 per share (the “Purchase Price”) (such sale, the “Offering”).

The Offering was made pursuant to that certain Registration Statement on Form S-3ASR (File No. 333-291507), filed with the Securities and Exchange Commission (the “SEC”) on November 13, 2025, including the prospectus contained therein and the prospectus supplement dated November 14, 2025, filed with the SEC on November 14, 2025.

Share Repurchase Agreement

Additionally, on November 14, 2025, the Company entered into a share repurchase agreement with the Selling Shareholder pursuant to which the Selling Shareholder agreed to sell to the Company, and the Company agreed to purchase from the Selling Shareholder, 1,717,948 shares of Common Stock at the Purchase Price (the “Repurchase”). The Repurchase is being conducted under the share repurchase authorization previously disclosed on the Company’s Current Report on Form 8-K filed with the SEC on September 15, 2025. The Offering is not conditioned upon the Repurchase.

The closings of the Offering and the Repurchase are expected to occur on November 17, 2025, subject to the satisfaction of customary closing conditions. The Company is not selling any of the shares described in the Offering and accordingly will not receive any net proceeds from the Offering.
