Material Changes vs. Prior Period
- Net Interest Income Expansion: NII increased by $11.0 million, driven by a 44 basis point expansion in NIM. This was primarily due to a decrease in the cost of funds (interest-bearing liabilities cost dropped to 3.11% from 3.55%) and lower average balances of short-term borrowings following the payoff of Bank Term Funding Program (BTFP) loans in 2024.
- Noninterest Income Decline: Noninterest income decreased 33.4% to $9.5 million. This decline was largely due to the absence of nonrecurring items present in 2024, specifically $3.1 million in Bank Owned Life Insurance (BOLI) death benefit proceeds and $1.1 million from a legal settlement related to Hurricane Ida.
- Noninterest Expense Increase: Expenses rose 4.3% to $65.7 million, driven by a $1.6 million increase in salaries and employee benefits and $1.0 million in acquisition expenses related to the WFB transaction.
- Capital Raise: In July 2025, the Company issued 32,500 shares of Series A Preferred Stock for net proceeds of $30.4 million to support the WFB acquisition and general corporate purposes.
- Loan Portfolio Mix: Commercial and industrial loans increased to 27.4% of the portfolio, while nonowner-occupied commercial real estate loans decreased to 20.8% as part of a strategy to optimize and de-risk the portfolio.
Guidance, Outlook, and Risks
Management Commentary: Management continues to focus on consistent, quality earnings through balance sheet optimization, originating high-quality variable-rate loans, and allowing higher-risk credits to run off. The acquisition of WFB expands the franchise into the Wichita Falls and north Dallas markets.
Outlook: The Company anticipates continued pressure on net interest margin if the yield on interest-earning assets decreases faster than the cost of funds in 2026. The Federal Reserve reduced the federal funds target rate by 75 basis points cumulatively in late 2025, and the outlook remains uncertain.
Key Risks:
- Interest Rate Risk: Significant fluctuations in interest rates impact net interest income and the valuation of the investment portfolio. Gross unrealized losses in the Available-for-Sale (AFS) portfolio were $46.4 million at year-end 2025.
- Geographic Concentration: Approximately 77% of deposits are in South Louisiana, exposing the Company to regional economic downturns and natural disasters (hurricanes, floods).
- Commercial Real Estate (CRE) Exposure: CRE loans (owner and nonowner-occupied) comprise approximately 42% of the total loan portfolio. Deterioration in this sector could require increased provisions for credit losses.
- Liquidity and Deposit Stability: Uninsured deposits represented approximately 34% of total deposits. The Company relies on core deposits and has $651.5 million in unused FHLB borrowing capacity.
- Cybersecurity: Increasing risks of cyberattacks and fraud, particularly with the adoption of new technologies and AI.
Investor Verification Checklist
- WFB Integration: Verify the progress of integrating WFB's operations and the realization of anticipated synergies in the first quarter of 2026.
- Deposit Cost Trends: Monitor the cost of interest-bearing deposits to ensure it does not rise significantly as the Company competes for core deposits in a lower-rate environment.
- CRE Asset Quality: Review the aging of commercial real estate loans and any changes in the allowance for credit losses specific to the CRE portfolio.
- Investment Portfolio: Assess the potential for realized losses if the Company is forced to sell AFS securities with gross unrealized losses of $46.4 million to meet liquidity needs.
- Preferred Stock Dividends: Confirm the payment of quarterly dividends on the Series A Preferred Stock (6.5% annual rate), as common stock dividends are restricted until preferred dividends are paid.
