Key Financial Metrics

Material Changes vs. Prior Period

• Profitability: Net income for the six months ended June 30, 2025, increased to $11.02 million from $8.32 million in the prior year period. This improvement is largely attributable to the absence of a $3.47 million pre-tax loss on the sale of available-for-sale securities that occurred in the first half of 2024 due to a strategic portfolio repositioning.
• Net Interest Income: NII increased 8.6% year-over-year for the six-month period to $34.84 million, driven by a $111 million increase in average earning assets, primarily loans, despite a 20 basis point decrease in yield on earning assets.
• Expense Growth: Noninterest expense increased 12.5% to $23.51 million for the six months ended June 30, 2025, compared to $20.90 million in 2024. Increases were seen across all categories, notably in salaries and employee benefits (due to hiring and adjustments) and professional fees.
• Asset Growth: Total assets grew 5.8% to $2.22 billion from $2.10 billion at year-end 2024. Gross loans held for investment increased 8.4% to $1.53 billion.
• Loan Portfolio Mix: Significant growth was observed in Acquisition, Development, and Construction (ADC) loans (+38.6%) and Marine Vessel loans (+14.3%).

Guidance, Outlook, and Risks

• Subsequent Event (IPO): On July 3, 2025, the Company completed its Initial Public Offering (IPO), selling 2,035,000 shares at $21.50 per share. The Company received net proceeds of approximately $34.0 million. Shares began trading on the NYSE under the ticker "COSO" on July 2, 2025.
• Interest Rate Risk: The Company maintains an asset-sensitive position. Management notes that a flat or inverted yield curve pressures Net Interest Margin (NIM). Sensitivity analysis indicates NII would increase 4.31% in a +100 basis point rate shock scenario over 12 months.
• Credit Quality: Nonperforming loans decreased to $14.70 million (0.96% of gross loans) from $15.01 million at year-end 2024. The ACL coverage ratio for nonperforming loans is 119.75%. Management cites improved performance in the Senior Housing portfolio as a driver for reduced special mention and substandard loans.
• Liquidity: The Company maintains strong liquidity with $43.3 million in cash and cash equivalents and significant unused borrowing capacity at the Federal Home Loan Bank ($169 million) and Federal Reserve Discount Window ($29.4 million).
• Risks: Key risks include concentration in commercial real estate and senior housing, sensitivity to interest rate changes, and the impact of economic conditions on borrower repayment ability.

Investor Verification Checklist

• IPO Proceeds Deployment: Verify the specific use of the $34.0 million in net IPO proceeds as disclosed in the final prospectus.
• Senior Housing Concentration: Review the specific underwriting standards and performance metrics for the $236.5 million Senior Housing loan portfolio, which represents 15.5% of total loans.
• Non-GAAP Reconciliations: Review the reconciliation of "Adjusted Net Income" and "Adjusted Return on Average Assets" to understand the impact of excluding the 2024 securities loss on year-over-year comparisons.
• Derivative Hedging: Examine the details of the $400.5 million notional amount of interest rate swaps and collars used to hedge interest rate risk and their effectiveness.
• Brokered Deposits: Monitor the level of brokered deposits ($307.9 million, or 15.6% of total deposits) and the associated cost of funds relative to core deposits.
