INCOME STATEMENT REVIEW

FOURTH QUARTER 2025 COMPARED TO THE THIRD QUARTER 2025

Net income for the quarter ended December 31, 2025, was $90.5 million, an increase of $12.8 million, or 16.5%, compared to net income of $77.7 million for the third quarter of 2025. Diluted earnings per share for the fourth quarter of 2025 was $1.33 per share compared to $1.13 per share for the third quarter of 2025.

Return on average stockholders’ equity was 12.27% and return on average assets was 1.49% for the quarter ended December 31, 2025, compared to a return on average stockholders’ equity of 10.60% and a return on average assets of 1.29% in the third quarter of 2025.

Net interest income before provision for credit losses

Net interest income before provision for credit losses increased $5.4 million, or 2.9%, to $195.0 million during the fourth quarter of 2025, compared to $189.6 million in the third quarter of 2025. The increase was due primarily to a decrease in interest deposit expense, partially offset by a decrease in interest income from loans and securities.

The net interest margin was 3.36% for the fourth quarter of 2025 compared to 3.31% for the third quarter of 2025.

For the fourth quarter of 2025, the yield on average interest-earning assets was 5.74%, the cost of funds on average interest-bearing liabilities was 3.14%, and the cost of average interest-bearing deposits was 3.12%. In comparison, for the third quarter of 2025, the yield on average interest-earning assets was 5.84%, the cost of funds on average interest-bearing liabilities was 3.32%, and the cost of average interest-bearing deposits was 3.28%. The decrease in the yield on average interest-bearing liabilities resulted mainly from lower interest rates on deposits driven by the lower repricing of maturing time deposits in the fourth quarter. The decrease in the yield on average interest-earning assets resulted mainly from lower interest rates on loans due to the decreasing rate environment. The net interest spread, defined as the difference between the yield on average interest-earning assets and the cost of funds on average interest-bearing liabilities, was 2.60% for the fourth quarter of 2025, compared to 2.52% for the third quarter of 2025.

Provision for credit losses

The Company recorded a provision for credit losses of $17.2 million in the fourth quarter of 2025 compared to $28.7 million in the third quarter of 2025. As of December 31, 2025, the allowance for credit losses increased by $11.9 million to $208.4 million, or 1.03% of gross loans, compared to $196.5 million, or 0.98% of gross loans as of September 30, 2025.

The following table sets forth the charge-offs and recoveries for the periods indicated:

Non-interest income

Non-interest income, which includes revenues from depository service fees, letters of credit commissions, securities gains (losses), wealth management fees, and other sources of fee income, was $27.8 million for the fourth quarter of 2025, an increase of $6.8 million, or 32.2%, compared to $21.0 million for the third quarter of 2025. The increase was primarily due to an increase of $6.4 million in unrealized gains on equity securities, when compared to the third quarter of 2025.

Non-interest expense

Non-interest expense increased $4.1 million, or 4.6%, to $92.2 million in the fourth quarter of 2025 compared to $88.1 million in the third quarter of 2025. The increase was primarily due to an increase in salaries and employee benefits costs driven by higher performance-based incentive accruals. The efficiency ratio, defined as non-interest expense divided by the sum of net interest income before provision for loan losses plus non-interest income, was 41.36% in the fourth quarter of 2025 compared to 41.84% for the third quarter of 2025.

Income taxes

The effective tax rate for the fourth quarter of 2025 was 20.23% compared to 17.18% for the third quarter of 2025. The effective tax rate for the third and fourth quarter of 2025 includes the impact of low-income housing tax credits.
