1 Taxable-equivalent rates used where applicable.

Net interest income increased $52 million, or 8%, in the third quarter of 2025, relative to the prior year period, primarily due to lower funding costs. The increase was further supported by a favorable shift in the composition of average interest-earning assets, reflecting growth in higher-yielding loans and a decline in lower-yielding money market investments and securities. As a result, the net interest margin improved to 3.28%, compared with 3.03%.

The yield on average interest-earning assets, net of hedging activity, was 5.16% for the third quarter of 2025, compared with 5.35% in the prior year period, reflecting lower interest rates. The yield on average money market investments declined 100 basis points to 4.67%, while the net yield on average loans decreased 24 basis points to 5.91%. Additionally, the net yield on average securities declined 13 basis points to 2.73% during the third quarter of 2025.

The rate paid on total deposits and interest-bearing liabilities was 1.92% for the third quarter of 2025, compared with 2.36% in the prior year period. The total cost of deposits was 1.67%, compared with 2.14%, reflecting the lower interest rate environment.

Average interest-earning assets declined $111 million from the prior year quarter. This decrease was primarily attributable to a $1.2 billion reduction in average money market investments and a $1.2 billion decrease in average securities, with the latter largely resulting from principal reductions. These declines were partially offset by a $2.1 billion increase in average loans and leases.

Average interest-bearing liabilities decreased $641 million, or 1%, from the prior year quarter. This decline was primarily attributable to a $925 million reduction in average interest-bearing deposits, driven by the migration of a consumer interest-bearing product into a new noninterest-bearing offering. The decrease was partially offset by a $284 million increase in average borrowed funds, reflecting an increase in long-term debt.

1 Effective the first quarter of 2025, capital markets fees and income includes the net CVA, which was previously disclosed under noncustomer-related noninterest income. During the third quarter of 2025, the net CVA was a loss of $11 million. This loss was primarily driven by an update to our valuation methodology, in addition to changes in other market factors.

2 Net of CVA. For information on non-GAAP financial measures, see pages 18-20.

Customer-related noninterest income increased $5 million, or 3%, compared with the prior year period. This growth was primarily driven by a $3 million increase in loan-related fees and income, largely resulting from increased loan sales activity. Excluding the impact of the net CVA loss, capital markets fees and income increased $7 million, or 25%, from the prior year period, benefitting from increased loan syndication activity and higher swap fee revenue.

Noncustomer-related noninterest income increased $12 million, or 86%, compared with the prior year period. This growth was primarily driven by a $10 million increase in dividends and other income, mainly attributable to a $6 million gain on the sale of a bank-owned property and higher dividends received on FHLB stock.

1 For information on non-GAAP financial measures, see pages 18-20.

Noninterest expense increased $25 million, or 5%, compared with the prior year quarter. Salaries and employee benefits expense increased $20 million, primarily due to higher severance and other salary-related costs, along with increased incentive compensation accruals reflecting improved profitability. Technology, telecom, and information processing expense increased $4 million, largely due to higher costs associated with application software, licensing, and maintenance.

Adjusted noninterest expense increased $21 million, or 4%. The efficiency ratio improved to 59.6%, compared with 62.5%, reflecting positive operating leverage as adjusted pre-provision net revenue increased $53 million, or 18%. For more information on non-GAAP financial measures, see pages 18-20.

Total investment securities decreased $1.1 billion, or 6%, to $18.2 billion, relative to the prior year quarter, primarily due to principal reductions, net of reinvestments.

Loans and leases, net of unearned income and fees, increased $1.4 billion, or 2%, to $60.3 billion, relative to the prior year quarter. This growth was driven by a $1.0 billion increase in consumer loans, primarily within the 1-4 family residential loan portfolio, and a $394 million increase in commercial loans, primarily within the commercial and industrial loan portfolio.

During the third quarter of 2025, we recorded a $49 million provision for credit losses, compared with $13 million during the prior year period. The allowance for credit losses (“ACL”) totaled $725 million at September 30, 2025, compared with $736 million at September 30, 2024. The year-over-year decrease in the ACL primarily reflects lower reserves associated with commercial real estate (“CRE”) portfolio-specific risks, partially offset by more adverse economic scenarios and increased lending activity. The ratio of ACL to total loans and leases was 1.20% at September 30, 2025, compared with 1.25% at September 30, 2024.

Net loan and lease charge-offs totaled $56 million in the third quarter of 2025, compared with $3 million in the prior year quarter. This increase included $50 million in charge-offs associated with revolving lines of credit extended to two related commercial borrowers to finance the origination and purchase of commercial mortgages. Additionally, we have established a full reserve against the remaining $10 million exposure to these loans.

At September 30, 2025, nonperforming assets totaled $324 million, or 0.54% of total loans and leases and other real estate owned, compared with $368 million, or 0.62%, in the prior year period. Nonperforming assets remained primarily concentrated in the commercial and industrial, term CRE, and consumer 1-4 family residential loan portfolios. Classified loans totaled $2.4 billion, or 4.00% of total loans and leases, compared with $2.1 billion, or 3.55%, in the prior year period, and decreased from $2.7 billion, or 4.43%, in the prior quarter.

Total deposits decreased $840 million, or 1%, compared with the prior year quarter, and increased $1.1 billion, or 1%, from the prior quarter. Interest-bearing deposits decreased $2.0 billion from the prior year quarter, primarily due to the migration of a consumer interest-bearing product into a new noninterest-bearing offering, as well as a reduction in brokered deposits. This decline was partially offset by a $1.2 billion increase in noninterest-bearing demand deposits, mainly driven by the aforementioned product migration.

At September 30, 2025, customer deposits (excluding brokered deposits) totaled $71.1 billion, compared with $70.5 billion at September 30, 2024. These balances included approximately $6.8 billion and $7.3 billion of reciprocal deposits, respectively. The loan-to-deposit ratio was 81%, compared with 78% in the prior year quarter.

Total borrowed funds, primarily composed of secured borrowings, increased $1.8 billion, or 51%, compared with the prior year quarter. This growth was driven by higher levels of long-term debt and short-term advances from the FHLB, partially offset by a reduction in borrowings under the FRB Bank Term Funding Program. The increase in long-term debt reflects the issuance of $500 million in 4.70% Fixed-to-Floating Senior Notes during the third quarter of 2025, and $500 million in 6.82% Fixed-to-Floating Subordinated Notes during the fourth quarter of 2024. These issuances were partially offset by the redemption of $88 million in 6.95% Fixed-to-Floating Subordinated Notes, also during the fourth quarter of 2024.

Preferred stock decreased $374 million due to the redemption of the outstanding shares of our Series G, I, and J preferred stock during the fourth quarter of 2024. The common stock dividend was $0.45 per share, compared with $0.41 per share during the third quarter of 2024.

Accumulated other comprehensive income (loss) (“AOCI”) was a loss of $2.1 billion at September 30, 2025, an improvement of $280 million when compared with a loss of $2.3 billion at September 30, 2024. The AOCI loss largely reflects a decline in the fair value of fixed-rate available-for-sale securities as a result of changes in interest rates. Absent any sales or credit impairment of these securities, the unrealized losses will not be recognized in earnings. We do not intend to sell any securities with unrealized losses. Although changes in AOCI are reflected in shareholders’ equity, they are currently excluded from regulatory capital, and therefore do not impact our regulatory capital ratios.

Estimated common equity tier 1 (“CET1”) capital was $7.7 billion, an increase of 7%, compared with $7.2 billion in the prior year period. The estimated CET1 capital ratio was 11.3%, compared with 10.7%. Tangible book value per common share increased $5.52, or 17%, to $38.64, mainly due to an increase in retained earnings and reduced unrealized losses in AOCI.
