Key Financial Metrics

Material Changes vs. Prior Period

• Profitability Surge: Net income for Q2 2025 increased by approximately 75% compared to Q2 2024 ($4.59 million vs. $2.62 million). This was primarily driven by a $2.4 million decrease in total interest expense due to lower deposit costs.
• Net Interest Income: Net interest income rose $3.2 million (20.6%) year-over-year for the quarter, with the Net Interest Margin (NIM) expanding 55 basis points to 3.75%.
• Expense Management: Non-interest expense increased $1.9 million year-over-year, largely due to one-time costs ($1.8 million) associated with pivoting away from certain Banking-as-a-Service (BaaS) operations, including severance and contract termination fees. Excluding these items, operating expenses were relatively flat.
• Asset Quality Improvement: Non-performing loans decreased significantly from $21.7 million at year-end 2024 to $7.2 million at June 30, 2025. The company recorded a recovery of credit losses of $528,000 for the quarter, compared to a provision of $931,000 in the prior year.
• Balance Sheet Contraction: Total assets decreased $113.3 million from December 31, 2024, driven by a $74.4 million reduction in cash and cash equivalents and a $43.1 million decrease in net loans.

Guidance, Outlook, and Risks

Management Commentary: Management highlighted a strategic pivot away from certain BaaS services to focus on core banking. While this generated one-time costs in Q2, it is expected to streamline operations. The company successfully reduced funding costs by repricing deposits and exercising call options on wholesale CDs.

Risks and Contingencies:

• CRE Concentration: The company holds a significant concentration in Commercial Real Estate (CRE). Construction and land development loans represented 108.8% of risk-based capital, and total CRE loans represented 365.9% of risk-based capital. Management notes that while stress tests show capital ratios remain well above regulatory minimums, the portfolio is sensitive to the Washington, D.C. real estate market.
• Interest Rate Sensitivity: Net interest income is sensitive to interest rate fluctuations. Stress simulations indicate that a 100 basis point decrease in rates would reduce net interest income by 1.48% over the next year.
• Economic Factors: Risks include federal spending reductions, potential government layoffs in the primary market area, and the impact of new legislation (the "One Big Beautiful Bill") on tax credits and economic conditions.

Investor Verification Checklist

• BaaS Pivot Impact: Verify the long-term cost savings and revenue implications of exiting the BaaS segment versus the one-time charges incurred in Q2.
• CRE Portfolio Health: Review the specific performance of the $328.5 million construction and land development portfolio, which saw a $64.9 million decrease but remains a high-risk concentration.
• Deposit Stability: Assess the sustainability of the deposit base given the $109 million outflow since year-end 2024 and the reliance on wholesale deposits (approx. 36% of interest expense).
• Non-Performing Loan Resolution: Confirm the status of the remaining $7.2 million in non-performing loans, noting that 52% is attributable to a single relationship.
• Tax Credit Investments: Monitor the status of New Market Tax Credit (NMTC) allocations and the impact of the permanent extension of the program on future tax liabilities.
