The results depicted in the table above are dependent on material assumptions, such as prepayment rates, decay rates, pricing decisions on loans and deposits, and other factors, which management believes are reasonable. These assumptions may be impacted by customer preferences or competitive influences and therefore actual experience may differ from the assumptions in the model. Accordingly, although the tables provide an indication of the Company’s interest rate risk exposure at a particular point in time, such measurements are not intended to and do not provide a precise forecast of the effect of changes in market interest rates, and actual results may differ.

The most significant market factors affecting the Company’s net interest income during the nine months ended September 30, 2025 were the shape of the U.S. Government securities and interest rate swap yield curve, the U.S. prime interest rate, the Secured Overnight Financing Rate, and other interest rates offered on long-term fixed rate loans.

The Company manages the interest rate risk inherent in both its loan and borrowing portfolios by using interest rate swap agreements and interest rate caps and floors. An interest rate swap is an agreement in which one party agrees to pay a floating rate of interest on a notional principal amount in exchange for receiving a fixed rate of interest on the same notional amount for a predetermined period from the other party. Interest rate caps and floors are agreements where one party agrees to pay a floating rate of interest on a notional principal amount for a predetermined period to a second party if certain market interest rate thresholds are realized. While interest is paid or received in swap, cap, and floors agreements, the notional principal amount is not exchanged. The Company may also manage the interest rate risk inherent in its mortgage banking operations by entering into forward sales contracts under which the Company agrees to deliver whole mortgage loans to various investors. See Note 8, “Derivative and Hedging Activities” within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report for additional information regarding the Company’s derivative financial instruments.

Movements in foreign currency rates or commodity prices do not directly or materially affect the Company’s earnings. Movements in equity prices may have a modest impact on earnings by affecting the volume of activity or the amount of fees from investment-related business lines. See Note 4, “Securities” within the Notes to Consolidated Financial Statements included in Part I. Item 1 of this Report.

Operational Risk Operational risk is the risk arising from human error or misconduct, transaction errors or delays, inadequate or failed internal systems or processes, data unavailability, loss, or poor quality, or adverse external events. Operational risk includes fraud risk and model risk. Potential operational risk exposure exists throughout the Company. The continued effectiveness of colleagues and operational infrastructure are integral to mitigating operational risk, and any shortcomings subject the Company to risks that vary in size, scale and scope.

Reputation Risk Reputation risk is the risk arising from negative public opinion of the Company and the Bank. Management seeks to mitigate reputational risk through actions that include a structured process of customer complaint resolution and ongoing reputational monitoring.

Regulatory and Compliance Risk Regulatory and Compliance risk is the risk arising from violations of laws or regulations, non-conformance with prescribed practices, internal bank policies and procedures, or ethical standards. Compliance risk includes consumer compliance risk, legal risk, and regulatory compliance risk. Management seeks to mitigate compliance risk through compliance training and regulatory change management processes.

Technology and Cyber Risk Technology and Cyber risk is the risk of losses or other impacts arising from the failure of technology systems to function in accordance with expectations and business requirements. Technology risks include technical failures, unlawful tampering with technical systems, cyber security, terrorist activities, ineffectiveness or exposure due to interruption in third party support. Management seeks to mitigate technology risk through appropriate security and controls over data and its technological environment. The Bank manages cybersecurity threats proactively and maintains robust controls to protect its critical systems and data by investing in secure, reliable and resilient technology infrastructure, fostering a culture of technology risk awareness and continuously improving its technology risk management practices.
