Investor Presentation | First Quarter 20255 Most Recent Quarter Highlights  Pre-tax pre-provision ROAA and ROAE were 1.61% and 12.64%, respectively, for the quarter ended March 31, 2025, and 1.71% and 14.38%, respectively, for the same quarter in the prior year.  Our efficiency ratio was 60.4% for the quarter ended March 31, 2025, compared to 59.6% for the trailing quarter end and 57.4% for the quarter ended March 31, 2024. Operating Leverage and Profitability  Net interest margin (FTE) of 3.73% compared favorably to 3.68% from the same quarter of the prior year.  Average yield on earning assets (FTE) of 5.15% was 2 basis points higher than the 5.13% in the quarter ended March 31, 2024, but 7 basis points lower than the 5.22% in the quarter ended December 31, 2024.  Cost of interest-bearing liabilities for the quarter was 2.18%, or a 9 basis points decrease from 2.27% in the trailing quarter, and a 6 basis points decrease from the 2.24% for the quarter ended March 31, 2024.  The Company’s average cost of total deposits of 1.43% decreased 3 basis points from the trailing quarter. Net Interest Income and Margin  Loan balances increased $52.3 million or 3.1% (annualized) from the trailing quarter  Deposit balances increased $117.8 million or 5.8% (annualized) from the trailing quarter  Loan to deposit ratio was to 83.1% at March 31, 2024, compared to 83.7% in the trailing quarter  Average other borrowings decreased by $5.7 million to $89.5 million as compared to the trailing quarter; while on balance sheet liquidity increased by $163.3 million in the quarter, to $308.3 million as of March 31, 2025. Balance Sheet Management  Readily available and unused funding sources total approximately $4.1 billion and represent 50% of total deposits and 160% of total estimated uninsured deposits.  No reliance on brokered deposits or FRB borrowing facilities during 2025 or 2024 Liquidity  The allowance for credit losses to total loans was 1.88% at March 31, 2025 compared to 1.85% at December 31, 2024, as manageable credit migration was observed despite having net recoveries during the quarter.  With the allowance for credit losses representing more than 2.0x of non-performing assets and 1.88% of total loans, we believe that sufficient coverage has been created for a potentially volatile credit environment. Past due and non-performing loan levels remain substantially below peer averages. Credit Quality  Average non-interest-bearing deposits comprised 30.7% of average total deposits for the quarter.  Approximately a 50/50 split between consumer and business deposit dollars reflects a diversified client base.Diverse Deposit Base  All regulatory capital ratios continue to climb, with six successive quarters of increases  Maintained the quarterly dividend of $0.33  Approximately 740,000 shares remain authorized for repurchase  Tangible capital ratio of 9.9% at March 31, 2025, an increase from 8.9% at March 31, 2024, through the combined impacts of retained earnings and reduction in accumulated other comprehensive loss.
