RBB Bancorp (NASDAQ: RBB) lifts margin and trims problem assets in third quarter

What happened

RBB Bancorp (NASDAQ: RBB) reported third-quarter 2026 net income of $12.6 million and declared a quarterly cash dividend of $0.16 per common share. Diluted earnings per share were $0.74, up from $0.59 in the second quarter of 2026. Return on average assets was 1.17%, compared with 0.97%.

Net interest income rose to $31.8 million from $30.1 million. Noninterest income increased to $5.1 million from $3.0 million. Noninterest expense was $19.5 million, up from $19.0 million. Nonperforming assets were $38.7 million, down $4.9 million, or 11.3%, from June 30, 2026. Book value per share increased to $31.75 from $31.51, and tangible book value per share rose to $27.44 from $27.23.

Total deposits were $3.4 billion at September 30, 2026, and the loan-to-deposit ratio was 100.1%. The deposit increase came from a $63.3 million rise in retail deposits, partly offset by a $58.7 million decline in wholesale deposits. Retail deposits included a $46.5 million increase in non-maturity interest-bearing accounts and a $51.6 million increase in time deposits, partly offset by a $34.7 million drop in demand deposits.

Why it matters

OptimistFi's case is that RBB works if its Los Angeles-centered community-bank franchise can fund relationship loans at acceptable spreads while avoiding the credit accidents that erase small-bank earnings. This filing is mixed for that view. Net interest margin improved to 3.16% from 3.06% in the prior quarter, and nonperforming assets fell to $38.7 million from $43.6 million.

Quarterly net income rose from $10.1 million to $12.6 million, a $2.5 million increase on OptimistFi's calculation. But the quarter included a $2.7 million gain on the sale of an office building in Brooklyn, New York, and a $320,000 special dividend from the Federal Home Loan Bank. The loan-to-deposit ratio remained 100.1%, so the quarter still carried little deposit cushion.

What's next

Management will hold a conference call on Tuesday, October 20, 2026, at 11:00 a.m. Pacific time. That call is the next scheduled chance to hear whether the deposit mix and margin trends are carrying into the fourth quarter.

The dividend is payable on November 12, 2026 to shareholders of record on October 30, 2026. A stronger case would pair stable margins and lower problem assets with more deposit growth that does not lean on wholesale funding. A weaker one would show the quarter's earnings lift fading once the building-sale gain and FHLB dividend drop out.
