Key Financial Metrics

Material Changes vs. Prior Period

• Profitability: Net income increased 49.4% year-over-year for the quarter ($16.3M vs. $10.9M) and 35.9% year-over-year for the nine-month period ($44.0M vs. $32.4M). This was driven by a 29.5% increase in net interest income.
• Balance Sheet Growth: Total assets grew 14.5% to $4.64 billion from $4.05 billion at year-end 2024. Total loans increased 10.0% to $3.89 billion, while total deposits rose 15.3% to $4.10 billion.
• Net Interest Margin (NIM): NIM expanded to 3.56% in Q3 2025 from 3.37% in Q3 2024, attributed to loan growth and improved loan yields, partially offset by higher deposit costs.
• Expense Management: Non-interest expense increased 20.4% quarter-over-year to $16.6 million, primarily due to a 21.9% rise in salaries and employee benefits linked to a 13.3% increase in headcount. Despite higher expenses, the efficiency ratio improved to 40.13% from 43.37%.
• Asset Quality: Non-accrual loans remained stable at 0.05% of total loans ($2.1 million). The allowance for credit losses to total loans ratio increased slightly to 1.08% from 1.07%.

Guidance, Outlook, and Risks

• Dividends: The board declared a quarterly cash dividend of $0.20 per share, payable November 10, 2025. A subsequent dividend of $0.20 per share was declared on October 16, 2025.
• Liquidity: The company maintains strong liquidity with $580.4 million in cash and cash equivalents and approximately $1.76 billion in unused borrowing capacity (FHLB, Federal Reserve Discount Window, and correspondent lines).
• Capital Adequacy: All regulatory capital ratios exceed "well-capitalized" thresholds. The Total Risk-Based Capital ratio was 13.59% and Tier 1 Leverage ratio was 9.78% as of September 30, 2025.
• Risks: Key risks include concentration in Northern California real estate (86.9% of loans), interest rate sensitivity, and potential economic downturns affecting borrower repayment. The company notes that commercial real estate loans represent a significant concentration relative to risk-based capital (589.24%).
• Regulatory: The company is an Emerging Growth Company (EGC) and has elected not to opt out of the extended transition period for new accounting standards. Recent legislative changes (e.g., "One Big Beautiful Bill Act") are not expected to have a significant immediate impact.

Investor Verification Checklist

• Deposit Concentration: Verify the stability of the top 120 deposit relationships, which represent 60.14% of total deposits, with the largest single relationship at $290 million (7.07% of total deposits).
• Commercial Real Estate (CRE) Exposure: Review the specific performance of the CRE portfolio, particularly the "Watch" and "Substandard" categories, given the high concentration (84.4% of loans) and the downgrade of one borrower ($11.6M) to substandard status in Q3.
• Cost of Funds: Monitor the trend in interest expense on deposits, which increased significantly due to higher balances, and assess the sustainability of the current NIM expansion.
• Headcount vs. Efficiency: Evaluate the long-term impact of the 13.3% increase in headcount on the efficiency ratio as loan growth continues.
• Unfunded Commitments: Assess the potential drawdown risk of $477.6 million in unfunded loan commitments and standby letters of credit.
