RBB Bancorp and its subsidiaries, Royal Business Bank and RBB Asset Management Company, announced that its Board of Directors authorized a stock repurchase plan providing for the repurchase of up to 1 million shares of the Company's outstanding common stock through June 30, 2028. The Repurchase Plan represents a dollar amount of approximately $25 million, based on the Company's current stock price, and represents approximately 6% of the Company's current outstanding shares. These transactions reflect the Company's strong capital position and ample liquidity and are part of the Company's ongoing capital management strategy.

The Repurchase Plan permits shares to be purchased in open market or private transactions, through block trades, and pursuant to any trading plan that may be adopted in accordance with Rules 10b5-1 and 10b-18 of the Securities and Exchange Commission. The authorized Repurchase Plan may be suspended, terminated or modified at any time for any reason, including market conditions, the cost of repurchasing shares, the availability of alternative investment opportunities, liquidity, and other factors deemed appropriate. These factors may also affect the timing and amount of share repurchases. The Repurchase Plan does not obligate the Company to purchase any particular number of shares.

On May 29, 2025, the Company's Board of Directors authorized the repurchase of up to $18 million of common stock through June 30, 2026, of which $4.1 million was available as of March 31, 2026. In the second quarter of 2026, the Company repurchased the remaining available amount under this plan which effectively exhausted this plan.

The Company also intends to redeem $40.0 million of the 4.0% Fixed to Floating Rate Subordinated Notes due March 31, 2031, with an expected redemption date of July 1, 2026. The Notes became redeemable in whole, or in part, beginning on April 1, 2026, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus any accrued and unpaid interest. Beginning on April 1, 2026, the 4.00% fixed interest rate reset to a floating rate equal to three-month term SOFR plus a spread of 329 basis points, which equaled 6.98% on that date. Accordingly, the total amount related to the Notes being redeemed, plus any accrued and unpaid interest, is approximately $40.7 million.

Immediately after the redemption, $80.0 million aggregate principal amount of the Notes will be outstanding and the interest rate will reset on July 1, 2026, to the then three-month term SOFR plus a spread of 329 basis points. RBB Bancorp is a community-based financial holding company headquartered in Los Angeles, California. As of March 31, 2026, the Company had total assets of $4.2 billion.
