Net Interest Income and Net Interest Margin

Second quarter 2025 net interest income of $300 million increased $14 million from the prior quarter and increased $43 million from the same period last year. The net interest margin increased to 3.04%, reflecting a 7 basis point increase from the prior quarter and a 29 basis point increase from the same period last year.

• The average yield on total loans for the second quarter of 2025 increased 6 basis points from the prior quarter and decreased 32 basis points from the same period last year to 5.89%.
• The average cost of total interest-bearing liabilities for the second quarter of 2025 decreased 4 basis points from the prior quarter and decreased 58 basis points from the same period last year to 3.02%.
• The net free funds benefit for the second quarter of 2025 decreased 2 basis points from the prior quarter and decreased 14 basis points from the same period last year to 0.56%.

Based on our latest forecasts for balance sheet growth and mix, and current market conditions, we now expect total net interest income growth of 14% to 15% in 2025.

Noninterest Income

Second quarter 2025 total noninterest income of $67 million increased $8 million from the prior quarter and increased $2 million from the same period last year. The increase relative to the prior quarter was primarily driven by a $7 million loss recognized in the first quarter of 2025 related to the settlement of the mortgage sale originally announced in December of 2024. With respect to second quarter 2025 noninterest income line items:

• Capital markets, net increased $1 million from the prior quarter and $1 million from the same period a year ago.
• Card-based fees increased $1 million from the prior quarter and decreased $1 million from the same period last year.
• Wealth management fees increased $1 million from the prior quarter and increased slightly from the same period last year.

After adjusting to exclude the fourth quarter 2024 and first quarter 2025 impacts of the mortgage and investment securities sales we announced in December 2024, we now expect total noninterest income growth of between 1% and 2% in 2025.

Noninterest Expense

Second quarter 2025 total noninterest expense of $209 million decreased $1 million from the prior quarter and increased $13 million from the same period last year. With respect to second quarter 2025 noninterest expense line items:

• Personnel expense increased $3 million from the prior quarter and increased $5 million from the same period last year.
• Business development and advertising expense increased $1 million from the prior quarter and increased slightly from the same period last year.
• Legal and professional expense increased $1 million from the prior quarter and increased $2 million from the same period last year.
• Occupancy expense decreased $3 million from the prior quarter and decreased slightly from the same period last year.
• FDIC assessment expense decreased $1 million from the prior quarter and increased $3 million from the same period last year.

After adjusting to exclude the $14 million impact of the loss on prepayments of FHLB advances recognized in the fourth quarter of 2024, we now expect total noninterest expense to grow by 4% to 5% in 2025.

Taxes

Second quarter 2025 tax expense was $28 million, compared to $19 million of tax expense in the prior quarter and $13 million of tax benefit in the same period last year. The effective tax rate for the second quarter of 2025 was 20.34%, compared to 16.03% in the prior quarter.

We continue to expect the annual effective tax rate to be between 19% and 21% in 2025.

Credit

Second quarter 2025 provision for credit losses on loans was $18 million, compared to a provision of $13 million in the prior quarter and a provision of $23 million in the same period last year. With respect to second quarter 2025 credit quality:

• Nonaccrual loans of $113 million decreased $22 million from the prior quarter and decreased $41 million from the same period last year. The nonaccrual loans to total loans ratio was 0.37% in the first quarter, down from 0.44% in the prior quarter and down from 0.52% in the same period last year.
• Second quarter 2025 net charge offs of $13 million increased compared to net charge offs of $9 million in the prior quarter and decreased compared to net charge offs of $21 million in the same period last year.
• The allowance for credit losses on loans (ACLL) of $412 million increased $5 million compared to the prior quarter and increased $22 million compared to the same period last year. The ACLL to total loans ratio was 1.35% in the first quarter, up from 1.34% in the prior quarter and up from 1.32% in the same period last year.

In 2025, we continue to expect to adjust provision to reflect changes to risk grades, economic conditions, loan volumes, and other indications of credit quality.

The Company's capital position remains strong, with a CET1 capital ratio of 10.20% at June 30, 2025. The Company's capital ratios continue to be in excess of the Basel III "well-capitalized" regulatory benchmarks on a fully phased in basis.
