Acquisition of Eastern Michigan Completed
Consummation of Eastern Michigan on December 31, 2025; acquisition contributed to deposit growth, loan growth, higher securities balances and helped stabilize net interest margin and liquidity metrics.
Net Interest Margin Resilience

Strong Asset Quality
Non-performing assets to total assets were 11 basis points (0.11%) as of March 31, 2026; non-performing loans average ~12 basis points over 6.25 years; allowance for credit losses was 1.18% of total loans (~~10x NPAs), indicating strong coverage.
Robust Deposit Growth and Improved Liquidity Mix
Deposits grew 15.8% year-over-year for Q1 2026; loan-to-deposit ratio improved to 89% (from 91% at 12/31/2025 and 98% at 12/31/2024); non-interest-bearing deposits represent ~25% of mix and lower-cost deposits increased (from 20% at end-Q3 2025 to 25% at 3/31/2026).
Multi-Year Compound Growth Rates
Five-year compound annual growth rates: deposits +9.2% and total loans +8.6%; five-year tangible value per share CAGR 9% and five-year EPS CAGR 15.1%, placing the company in the top tier of its proxy group.

Lower Funding Cost
Cost of all deposits declined 46 basis points YoY in Q1 2026, and interest expense declined $2.3 million YoY, helping support NIM despite yield pressures on assets.
