Commercial Bancgroup, Inc.

SHARE REPURCHASE PROGRAM

HARROGATE, TN (April 27, 2026) – Commercial Bancgroup, Inc. (“Commercial”) (NASDAQ:CBK), the parent company for Commercial Bank, announced today that on April 27, 2026, the board of directors of Commercial (the “Board”) declared a quarterly cash dividend of $0.10 per share of Commercial common stock payable on June 30, 2026, to shareholders of record as of the close of business on June 15, 2026.

Commercial also announced that the Board authorized a stock repurchase plan (the “2026 Repurchase Program”) pursuant to which Commercial may repurchase, from time to time, up to an aggregate of $10 million of its outstanding common stock. The 2026 Repurchase Program will expire on April 30, 2027, unless extended by the Board.

“This stock repurchase authorization highlights our confidence in Commercial’s business and our outlook for continued growth,” stated Terry L. Lee, Commercial’s President and CEO. “We believe the stock repurchase plan is a solid investment for our shareholders and provides us with the opportunity to leverage our strong financial position to improve our earnings per share.”

Repurchases under the 2026 Repurchase Program may be effected from time to time in the open market, in privately negotiated transactions, or otherwise in compliance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in each case subject to applicable regulatory requirements and other factors that may be considered by Commercial in its sole discretion. Repurchases may also be made pursuant to a trading plan under Rule 10b5-1 of the Exchange Act, which would permit shares to be repurchased when Commercial might otherwise be precluded from doing so because of self-imposed trading blackout periods or other regulatory restrictions.

Commercial intends to fund the 2026 Repurchase Program with a combination of cash on hand and cash generated from ongoing operations, and repurchased shares will be become authorized but unissued shares. The 2026 Repurchase Program does not obligate Commercial to repurchase any particular amount of common stock and may be extended, modified, amended, suspended, or discontinued by the Board at any time. There can be no guarantee as to the exact number or value of shares that will be repurchased by Commercial. The timing and amount of share repurchases under the 2026 Repurchase Program will depend on a number of factors, including Commercial’s stock price performance, ongoing capital planning considerations, general market conditions, and applicable legal requirements.
