Key Financial Metrics

Material Changes vs. Prior Period

• Profitability Growth: Net income increased 5.5% year-over-year, driven by higher net interest income and a reduction in credit loss expense.
• Interest Rate Environment: Net interest income rose 2.7% due to a decrease in interest expense (down 8.3% YoY), primarily from a redistribution of rates paid on deposits, while interest income remained relatively flat.
• Non-Interest Income Surge: Non-interest income jumped 15.7% YoY. This was largely due to a reversal of losses recorded on merchant banking investments in the prior year period, resulting in a net gain of $2.2 million compared to a $1.3 million loss in Q1 2025.
• Expense Management: Non-interest expenses increased 3.1% YoY, primarily attributed to higher employee compensation and benefits to retain workforce in a competitive market.
• Asset Growth: Total loans grew 2.0% quarter-over-quarter, with commercial real estate loans comprising approximately 66% of the total portfolio.

Guidance, Outlook, Risks, and Contingencies

• Capital Position: The company remains well-capitalized, exceeding all Basel III requirements. The Common Equity Tier 1 (CET1) ratio was 23.15% as of March 31, 2026. Management notes that new "2026 Proposals" for Basel IV capital rules were unveiled in March 2026, but the final implementation timeline remains uncertain.
• Dividends and Buybacks: A quarterly dividend of $0.73 per share was paid in February 2026. The Board authorized a stock repurchase program of up to $150 million effective March 15, 2026. As of May 4, 2026, approximately $145.3 million remained available under the program.
• Key Risks:
  • Geopolitical & Trade: Exposure to U.S.-Mexico trade relations, including potential tariffs and border crossing reductions.
  • Interest Rate Sensitivity: The company maintains an asset-sensitive position, which benefits from rising rates but could contract if rates fall.
  • Credit Quality: Concentration in commercial real estate (hotels, multifamily, construction) poses risks related to market value deterioration and occupancy levels.
  • Regulatory: Potential changes in capital rules (Basel IV) and increased scrutiny on fees and overdraft services by the CFPB.
• Unusual Items: No material unusual items were reported for the quarter. The increase in non-interest income was primarily a normalization from prior-year investment losses rather than a one-time gain.

Investor Verification Checklist

• Commercial Real Estate Concentration: Verify the specific performance of the $6.35 billion commercial real estate portfolio, particularly the $1.06 billion in hotel loans and $959 million in multifamily loans, given sensitivity to economic cycles.
• Deposit Cost Trends: Monitor the sustainability of the reduced interest expense on deposits; verify if rate reductions are sustainable or if competitive pressures will force rates higher.
• Merchant Banking Volatility: Assess the stability of non-interest income, noting the significant swing from losses in Q1 2025 to gains in Q1 2026 in the "Other investments" category.
• Non-Accrual Loans: Review the $160 million in non-accrual loans, specifically the increase in "Watch List - Doubtful" construction loans, to gauge future credit loss expense.
• Regulatory Capital Impact: Evaluate the potential impact of the newly proposed "2026 Proposals" for Basel IV capital rules on future capital requirements and dividend capacity.
