Material Changes vs. Prior Period
- Profitability Growth: Net income increased by $63.4 million, driven by higher net interest income, lower merger-related expenses, and reduced regulatory assessments. The efficiency ratio improved significantly to 44.55%.
- Asset Quality Deterioration: Nonperforming assets (NPA) increased to $150.8 million (0.69% of total loans and OREO) from $81.5 million in 2024. Nonaccrual loans rose to $137.2 million. Despite this, the allowance for credit losses remained well-capitalized at 242.7% of nonperforming loans.
- Balance Sheet Contraction: Total assets decreased by $1.10 billion, primarily due to a reduction in loans and investment securities. Total loans declined by $343.8 million, while deposits remained relatively flat with a slight increase of $101.1 million.
- Interest Rate Environment: Net interest margin expanded by 29 basis points to 3.22% as the cost of funds decreased to 1.61% from 1.87% in 2024, despite a decrease in average loan yields.
- Provision for Credit Losses: The Company recorded no provision for credit losses in 2025, compared to $9.1 million in 2024. This was offset by net charge-offs of $18.1 million.
Guidance, Outlook, and Strategic Developments
- Acquisition Activity:
- Completed (2026): Merged with American Bank Holding Corporation (Jan 1, 2026) and Southwest Bancshares, Inc. (Feb 1, 2026), adding 29 banking offices in South and Central Texas.
- Pending: Announced a definitive agreement to acquire Stellar Bancorp, Inc. (Jan 28, 2026), valued at approximately $2.00 billion. This would add 52 offices in the Houston and Beaumont areas.
- Capital Management: The Company maintains a "well-capitalized" status with a CET1 ratio of 17.55% and a leverage ratio of 11.93%. A new stock repurchase program was announced in January 2026 for up to 4.87 million shares.
- Risk Factors: Management highlights risks related to interest rate volatility, credit quality in commercial real estate and energy sectors, and the integration risks associated with the pending Stellar acquisition. The Company notes that nonperforming assets have increased, requiring continued monitoring of asset quality.
- Regulatory Environment: The Company is subject to extensive regulation by the Federal Reserve and FDIC. It remains compliant with all capital adequacy requirements.
Investor Verification Checklist
- Asset Quality Trends: Verify the trajectory of nonperforming assets, which nearly doubled year-over-year, and assess the adequacy of the allowance for credit losses relative to the rising nonaccrual balance.
- Acquisition Integration: Monitor the integration progress and accretion of the recent American and Southwest acquisitions, as well as the regulatory approval status and valuation assumptions for the pending Stellar acquisition.
- Commercial Real Estate Exposure: Review the concentration of commercial real estate loans (26.5% of total portfolio) and the specific risk grading of these assets given the increase in nonperforming assets.
- Deposit Stability: Analyze the composition of deposits, noting that noninterest-bearing deposits decreased by $330.5 million, while interest-bearing deposits increased, potentially impacting future cost of funds.
- Interest Rate Sensitivity: Evaluate the Company's asset sensitivity position as interest rates fluctuate, noting the recent expansion in net interest margin.
