AI Insight: RBB Financial Trends

RBB Bancorp's financial disclosure is too sparse to draw firm conclusions, with revenue flat at $1–2M and debt anchored at $120M across all periods.

• Revenue has been flat at $1–2M across all eight quarters, with no discernible growth trend.

• Total debt held essentially unchanged at $119–120M from Q2 2024 through Q1 2026, suggesting stable but static leverage.

• Operating cash flow is volatile, swinging from $2M in Q3 2025 to $24M in Q3 2024, with no consistent directional trend.

⚠ Op CF collapsed to $2M in Q3 2025 — the lowest in the dataset — before recovering to $19M in Q1 2026; sustainability of that rebound is unconfirmed.

⚠ Net income and operating income are entirely absent across all periods, making profitability assessment impossible.

AI Insight: RBB Ratio Trends

RBB Bancorp's ROIC swung violently — from 10.7% in Q1 2025 to 52.3% in Q1 2026 — masking underlying earnings volatility.

• ROIC collapsed from 32.8% in Q2 2024 to a trough of 7.9% in Q4 2025, a 24.9pp peak-to-trough drawdown.

• ROIC rebounded sharply to 52.3% in Q1 2026, the highest level in the observable period, suggesting a strong one-quarter recovery.

• Only one D/E reading is available (0.23 in Q4 2025), indicating a conservatively leveraged balance sheet at that snapshot.

⚠ ROIC swings of 40+ percentage points across consecutive quarters signal potential one-off items distorting underlying profitability trends.

⚠ OpMargin, NPM, ROE, and ROA are entirely absent — insufficient data to corroborate or contextualize the ROIC volatility.

⚠ Whether Q1 2026's 52.3% ROIC is sustainable or another single-quarter spike warrants close monitoring next quarter.
