Material Changes vs. Prior Period
- Profitability Surge: Net income increased 41.3% to $26.4 million, driven by a $10.6 million increase in net interest income and a negative provision for credit losses of $1.4 million (compared to a negative provision of $0.2 million in 2024).
- Net Interest Margin Expansion: NIM improved to 2.68% from 2.17%, primarily due to higher yields on loans (up 18 basis points) and a decrease in the cost of borrowings (down 88 basis points), partially offset by higher deposit costs.
- Deposit Growth: Total deposits grew 5.7% to $1.44 billion, led by a $45.8 million increase in money market and savings accounts and a significant rise in brokered certificates of deposit.
- Mortgage Banking Volume: Loan originations for sale decreased 4.6% to $2.05 billion, driven by a 7.0% drop in purchase products due to low housing inventory, partially offset by a 16.4% increase in refinance products.
- Asset Quality: Non-accrual loans increased slightly to $6.2 million (0.37% of total loans), while the allowance for credit losses decreased to 1.04% of total loans due to lower historical loss rates and qualitative adjustments.
Guidance, Outlook, and Risks
Management Commentary: Management highlighted the benefit of Fed funds rate cuts in reducing borrowing costs while maintaining competitive deposit rates. The company noted a shift in deposit mix toward higher-cost certificates of deposit (64.9% of total deposits). The mortgage banking segment faced headwinds from low housing inventory but benefited from increased refinance activity.
Key Risks and Contingencies:
- Interest Rate Risk: The company remains sensitive to interest rate fluctuations. A 100 basis point increase in rates is projected to decrease net interest income by 3.0% over the next 12 months.
- Concentration Risk: The loan portfolio is heavily concentrated in real estate (75.1% residential), with significant exposure to the Milwaukee metropolitan area. Multi-family and commercial real estate loans represent 64.8% of the portfolio.
- Regulatory and Compliance: As a highly regulated entity, the company faces risks related to capital requirements, deposit insurance assessments, and compliance with anti-money laundering and fair lending laws.
- Cybersecurity: The company relies heavily on third-party data processing and faces risks from cyber-attacks, though no material incidents were reported in 2025.
Investor Verification Checklist
- Deposit Cost Stability: Verify the sustainability of the deposit mix, specifically the reliance on certificates of deposit (64.9% of total) and the impact of brokered deposits on future funding costs.
- Mortgage Origination Trends: Monitor the trajectory of mortgage origination volumes and gross margins, given the sensitivity to housing inventory and interest rate environments.
- Commercial Real Estate Exposure: Review the performance of the $327.3 million commercial real estate and $758.4 million multi-family loan portfolios for early signs of stress in the local economy.
- Capital Ratios: Confirm that the company maintains its "well-capitalized" status (Total Capital Ratio of 20.49%) to support future dividends and share repurchases.
- Uninsured Deposits: Assess the stability of the $380 million in uninsured deposits (accounts over $250,000) and their potential sensitivity to market conditions.
