Taxes

The fourth quarter of 2025 had a tax expense of $26 million compared to $30 million of tax expense in the prior quarter and $16 million of tax benefit in the same period last year. The tax benefit in the comparable quarter was driven primarily by a loss on income before income taxes as a result of nonrecurring items associated with the balance sheet repositioning announced during the fourth quarter of 2024.

In 2026, we expect the annual effective tax rate to be between 19% and 21%, assuming no change in the corporate tax rate and excluding any impact from the acquisition of American National Corporation.

Credit

Full year 2025 provision for credit losses was $54 million, compared to a provision of $85 million in the prior year.

The fourth quarter 2025 provision for credit losses was $7 million, compared to a provision of $16 million in the prior quarter and a provision of $17 million in the same period last year. With respect to fourth quarter 2025 credit quality:

•Nonaccrual loans of $100 million decreased $6 million, or 5%, from the prior quarter and decreased $23 million, or 19%, from the same period last year.

The Company’s capital position remains strong, with a CET1 capital ratio of 10.49% at December 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.

Reconciliation & Definitions of Non-GAAP Items 34 Update 1 Prior period has been adjusted to conform with current presentation. 2 2020 announced initiatives impacting noninterest expense consisted of cost saving efforts that were executed during 3Q 2020. These initiatives included a $44.7 million loss on prepayment of FHLB advances, $9.6 million in severance, and $5.6 million in write-downs related to branch sales and lease breakage related to announced branch consolidations. 2020 announced initiatives impacting noninterest income consisted of a $163.3 million asset gain related to the sale of Associated Benefits and Risk Consulting, the Corporation's insurance division which was sold in June 2020, as well as a gain on sale of branches totaling $7.4 million, which occurred in 4Q 2020. 3 2025 announced initiatives include the loss on mortgage portfolio sale and loss on prepayment of FHLB advances as a result of the balance sheet repositioning that the Corporation announced in 4Q 2024. The net loss on the sale of investments is already excluded from noninterest income within the efficiency ratio. 4 During 4Q 2025, the Corporation announced its acquisition of American National Corporation. Related costs have been incurring since, thus are excluded from the adjusted efficiency ratio as an effort to represent current operational efficiency. During 1Q 2020, the Corporation finalized the acquisition of First Staunton. These costs, incurred in connection with the acquisition, represent nonrecurring costs.
