The Company evaluates its available for sale investment securities in an unrealized loss position on a quarterly basis. If the Company intends to sell the security or it is more likely than not that it will be required to sell before recovery, the entire unrealized loss is recorded as a loss within noninterest income in the Consolidated Statements of Income along with a corresponding adjustment to the amortized cost basis of the security. If the Company does not intend to sell the security and it is not more likely than not that it will be required to sell the security before recovery of its amortized cost basis, the Company evaluates whether any of the unrealized loss is related to a potential credit loss. The amount related to credit loss, if any, is recognized in earnings as a provision for credit loss and a corresponding allowance for credit losses is established; each is calculated as the difference between the estimate of the discounted future contractual cash flows and the amortized cost basis of the security. A number of qualitative and quantitative factors are considered by management in the estimate of the discounted future contractual cash flows, including the financial condition of the underlying issuer, current and projected deferrals or defaults and credit ratings by nationally recognized statistical rating agencies. The remaining difference between the fair value and the amortized cost basis of the security is considered the amount related to other market factors and is recognized in other comprehensive income, net of tax.

As of June 30, 2026, the Company did not intend to sell any of the securities in an unrealized loss position, and it is not more likely than not that the Company will be required to sell any such security prior to the recovery of its amortized cost basis, which may be maturity. Furthermore, approximately 88% of available for sale securities have the explicit backing of the U.S. government or a guarantee from a U.S. government-sponsored enterprise that has the same perceived credit risk as the U.S. government. Performance of these securities has been in line with broader market price performance, indicating that increases in market-based, risk-free rates, and not credit-related factors, are driving losses. When determining the fair value of the contractual cash flows for municipal and corporate securities, the Company considers historical experience with credit sensitive

securities, current market conditions, the financial condition of the underlying issuer, current credit ratings, ratings changes and outlook, explicit and implicit guarantees, and insurance programs. Based upon its review of these factors as of June 30, 2026, the Company determined that all such losses resulted from factors not deemed credit-related. As a result, no credit-related impairment was recognized in current earnings, and all unrealized losses for available for sale securities were recorded in other comprehensive income (loss). See Note 12, “Other Comprehensive Income (Loss)” for more information on the Company’s unrealized losses on securities.

The allowance for credit losses on held to maturity securities was $32 at each of June 30, 2026 and December 31, 2025. The Company monitors the credit quality of debt securities held to maturity using bond investment grades assigned by nationally recognized statistical ratings agencies. Updated investment grades are obtained as they become available from agencies. As of June 30, 2026, all of the debt securities held to maturity were rated A or higher by the ratings agencies.
