INCOME STATEMENT REVIEW

SECOND QUARTER 2026 COMPARED TO THE FIRST QUARTER 2026

Net income for the quarter ended June 30, 2026, was $92.2 million, an increase of $5.3 million, or 6.1%, compared to net income of $86.9 million for the first quarter of 2026. Diluted earnings per share for the second quarter of 2026 was $1.37 per share compared to $1.29 per share for the first quarter of 2026.

Return on average stockholders’ equity was 12.21% and return on average assets was 1.52% for the quarter ended June 30, 2026, compared to a return on average stockholders’ equity of 11.88% and a return on average assets of 1.47% in the first quarter of 2026.

Net interest income before provision for credit losses

Net interest income before provision for credit losses increased $6.7 million, or 3.5%, to $200.9 million during the second quarter of 2026, compared to $194.2 million in the first quarter of 2026. The increase was due primarily to an increase in interest income from loans and securities and a decrease in deposit interest expense.

The net interest margin was 3.48% for the second quarter of 2026 compared to 3.43% for the first quarter of 2026.

For the second quarter of 2026, the yield on average interest-earning assets was 5.66%, the cost of funds on average interest-bearing liabilities was 2.89%, and the cost of average interest-bearing deposits was 2.86%. In comparison, for the first quarter of 2026, the yield on average interest-earning assets was 5.70%, the cost of funds on average interest-bearing liabilities was 2.99%, and the cost of average interest-bearing deposits was 2.96%. The decrease in the cost of funds on average interest-bearing liabilities resulted mainly from lower interest rates on deposits driven by the lower repricing of maturing time deposits in the second quarter. The decrease in the yield on average interest-earning assets resulted mainly from lower interest rates on loans. 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 2.77% for the second quarter of 2026, compared to 2.71% for the first quarter of 2026.

Provision for credit losses

The Company recorded a provision for credit losses of $11.2 million in the second quarter of 2026 compared to $18.2 million in the first quarter of 2026. As of June 30, 2026, the allowance for loan losses increased by $10.1 million to $218.9 million, or 1.06% of gross loans, compared to $208.8 million, or 1.03% of gross loans as of March 31, 2026.

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

⁽¹⁾ Real estate loans include commercial real estate loans, residential mortgage loans and equity lines.

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 $21.4 million for the second quarter of 2026, an increase of $0.7 million, or 3.4%, compared to $20.7 million for the first quarter of 2026. The increase was primarily due to a $5.1 million reduction in losses related to investment securities repositioning activities and an increase of $0.8 million in wealth management fees partially offset by a decrease of $5.7 million in unrealized gains from equity securities, compared to the first quarter of 2026.

Non-interest expense

Non-interest expense increased $5.6 million, or 6.5%, to $92.3 million in the second quarter of 2026 compared to $86.7 million in the first quarter of 2026. The increase in non-interest expense in the second quarter of 2026 was primarily due to an increase of $3.1 million in amortization expense of investments of low income housing and alternative energy partnerships, an increase of $1.2 million in salaries and employee benefits, and an increase of $0.9 million in director fees offset, in part, by a decrease of $1.2 million in other real estate owned expense, when compared to the first quarter of 2026. 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 41.53% in the second quarter of 2026 compared to 40.35% for the first quarter of 2026.

Income taxes

The effective tax rate for the second quarter of 2026 was 22.35% compared to 20.98% for the first quarter of 2026. The effective tax rate for the second quarter of 2026 and first quarter of 2026 includes the impact of low-income housing tax credits.
