First quarter 2025 net interest income of $286 million increased $16 million from the prior quarter and increased $28 million from the same period last year. The net interest margin increased to 2.97%, reflecting a 16 basis point increase from the prior quarter and an 18 basis point increase from the same period last year.

We continue to expect total net interest income growth of 12% to 13% in 2025.

Noninterest Income

First quarter 2025 total noninterest income of $59 million increased $266 million from the prior quarter and decreased $6 million, or 10%, from the same period last year. The increase relative to the prior quarter was primarily driven by nonrecurring items recognized in the fourth quarter of 2024 as a result of the balance sheet repositioning announced in December of 2024. The decrease relative to the same period last year was primarily driven by a $7 million loss related to the settlement of the mortgage sale announced in December of 2024. With respect to first quarter 2025 noninterest income line items:

• The Company recognized a small investment securities net gain in the first quarter of 2025 as compared to a $148 million net loss in the prior quarter and a $4 million net gain in the same period last year. The loss in the prior quarter was primarily driven by a net loss on a sale of investments recognized in the fourth quarter of 2024 as a result of the balance sheet repositioning announced in December of 2024.
• The Company incurred a loss on mortgage portfolio sale of $7 million in the first quarter of 2025 as compared to a $130 million loss in the prior quarter and no loss in the same period last year. The current and prior quarter losses were driven by the mortgage portfolio sale as a result of the balance sheet repositioning announced in December of 2024.
• Capital markets, net decreased $5 million from the prior quarter and increased slightly from the same period last year.
• Wealth management fees decreased $2 million from the prior quarter and increased $1 million from the same period last year.
• Card-based fees decreased $2 million from the prior quarter and decreased $1 million 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 continue to expect total noninterest income growth of between 0% and 1% in 2025.

Noninterest Expense

First quarter 2025 total noninterest expense of $211 million decreased $14 million from the prior quarter, driven primarily by a $14 million expense for a loss on prepayments of FHLB advances recognized in the fourth quarter of 2024 as a result of the balance sheet repositioning announced in December of 2024, and increased $13 million from the same period last year. With respect to first quarter 2025 noninterest expense line items:

• Personnel expense decreased $2 million from the prior quarter and increased $5 million from the same period last year.
• Occupancy expense increased $1 million from the prior quarter and increased $2 million from the same period last year.
• FDIC assessment expense increased $1 million from the prior quarter and decreased $4 million from the same period last year.
• Other noninterest expense increased $1 million from the prior quarter and increased $7 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 continue to expect total noninterest expense to grow by 3% to 4% in 2025.

Taxes

First quarter 2025 tax expense was $19 million compared to a $16 million tax benefit in the prior quarter and $20 million of tax expense in the same period last year. First quarter 2025 tax expense included a $6 million benefit from a partial release of a valuation allowance on deferred taxes. The tax benefit recognized in the prior quarter was primarily driven by a loss on income before income taxes as a result of nonrecurring items associated with the balance sheet repositioning announced in December 2024. The effective tax rate for the first quarter of 2025 was 16.0% compared to an effective tax rate of 19.8% in the same period last year.

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

Credit

First quarter 2025 provision for credit losses on loans was $13 million, compared to a provision of $17 million in the prior quarter and a provision of $24 million in the same period last year. With respect to first quarter 2025 credit quality:

• Nonaccrual loans of $135 million increased $12 million from the prior quarter and decreased $44 million from the same period last year. The nonaccrual loans to total loans ratio was 0.44% in the first quarter, up from 0.41% in the prior quarter and down from 0.60% in the same period last year.
• First quarter 2025 net charge offs of $9 million decreased compared to net charge offs of $12 million in the prior quarter and decreased compared to net charge offs of $22 million in the same period last year.
• The allowance for credit losses on loans (ACLL) of $407 million increased $4 million compared to the prior quarter and increased $19 million compared to the same period last year. The ACLL to total loans ratio was 1.34% in the first quarter, down from 1.35% in the prior quarter and up from 1.31% 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.

Capital

The Company's capital position remains strong, with a CET1 capital ratio of 10.11% at March 31, 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.
