RBB Bancorp (RBB) has just wrapped up Q1 2026 with a recent run of quarterly numbers that includes Q4 2025 total revenue of US$31.7 million and net income of US$10.2 million, equivalent to basic EPS of about US$0.60, against a trailing twelve month revenue base of US$113.6 million and net income of US$31.9 million. Over the past year, the company has seen quarterly revenue move from US$22.7 million in Q4 2024 to US$31.7 million in Q4 2025, while basic EPS over that span stepped from US$0.25 to roughly US$0.60. This leaves investors to weigh a 28.1% trailing net profit margin against a longer history of earnings pressure.

With the recent results on the table, the next step is to see how these margins and earnings trends line up with the prevailing narratives around RBB Bancorp's growth potential and risks.

19.8% Earnings Growth Against Five Year Decline

• Over the last 12 months, RBB’s earnings grew 19.8%, which sits against a five year record where earnings declined by an average of 15.8% per year.
• What stands out for the bullish camp is that this 19.8% one year earnings lift comes alongside higher trailing net profit margins of 28.1% versus 25.4% a year earlier. However, critics point to the five year 15.8% annual earnings decline as evidence that recent strength may reflect a shorter term phase rather than a settled trend.
  • Supporters of the optimistic view highlight that trailing twelve month net income of US$31.9 million compares with quarterly net income of US$10.2 million in Q4 2025, suggesting recent quarters helped drive that trailing improvement.
  • Skeptics counter that the longer run decline and the unstable dividend track record mentioned in the risk summary mean investors still need to see more consistent performance before treating the 19.8% growth as a new normal.

Margins And Credit Quality Move Together

• Trailing net profit margin of 28.1% is paired with an allowance for bad loans at 98%, while non performing loans moved from US$81.0 million in Q4 2024 to US$44.6 million in Q4 2025.
• Bears focus on credit risk by pointing to the 98% allowance level as low and argue that any pickup in criticized loans or regional stress could push provisions higher. At the same time, the step down in non performing loans from US$81.0 million to US$44.6 million and net interest margin readings between 2.7% and 2.98% over recent quarters suggest asset quality and core spread income have not obviously broken in the direction that more cautious investors worry about.
  • Critics of the bullish case highlight that an allowance below 100% leaves less buffer if non performing loans climb again from the Q4 2025 level of US$44.6 million.
  • On the other side, supporters of the optimistic narrative point out that cost to income ratios between 57.2% and 59.4% over the trailing year are a step down from the Q1 2025 level of 65.1%, which lines up with the idea of better efficiency helping margins absorb credit costs.

On a day when earnings growth looks stronger on paper, bulls argue that disciplined lending and improving efficiency could keep margins resilient even if credit costs rise again. 🐂 RBB Bancorp Bull Case

P/E, DCF Gap And The 22.60 Target

• RBB trades on a P/E of 12.9x compared with a peer average of 13.8x and a US Banks industry average of 11.9x, against a current share price of US$24.18, an analyst price target of US$22.60, and a DCF fair value of about US$27.79.
• Bears focus on the fact that the analyst target of US$22.60 sits below the current US$24.18 price while earnings have fallen at 15.8% per year over five years. They argue this keeps pressure on the valuation even if the DCF fair value sits higher at US$27.79 and the P/E of 12.9x is modestly below the 13.8x peer average.
  • Skeptical investors point to the five year earnings decline rate of 15.8% per year as a key reason why an earnings multiple above the 11.9x industry average may still feel demanding.
  • Others counter that the roughly 13% gap between the DCF fair value of US$27.79 and the share price of US$24.18 shows some room if the recent 19.8% one year earnings growth and 28.1% margin can be maintained.

With the stock sitting between the analyst target and the higher DCF fair value, skeptics warn that the five year earnings decline still matters for anyone leaning too heavily on the recent turnaround. 🐻 RBB Bancorp Bear Case
