29SECOND QUARTER 2026 INVESTOR PRESENTATION About Non-GAAP Financial Measures: This presentation contains financial information determined by methods other than Generally Accepted Accounting Principles (“GAAP”). The financial highlights provide reconciliations between GAAP and adjusted financial measures including net income, noninterest income, noninterest expense, tax adjustments and other financial ratios. Management uses these non-GAAP financial measures in its analysis of the Company’s performance and believes these presentations provide useful supplemental information, and a clearer understanding of the Company’s performance. The Company believes the non-GAAP measures enhance investors’ understanding of the Company’s business and performance and if not provided would be requested by the investor community. These measures are also useful in understanding performance trends and facilitate comparisons with the performance of other financial institutions. The limitations associated with operating measures are the risk that persons might disagree as to the appropriateness of items comprising these measures and that different companies might define or calculate these measures differently. The Company provides reconciliations between GAAP and these non-GAAP measures. These disclosures should not be considered an alternative to GAAP. Presentation of Non-GAAP Financial Measures: Certain monetary amounts, percentages and other figures included in this report have been subject to rounding adjustments. Accordingly, figures shown as totals in certain tables may not be the arithmetic aggregation of the figures that precede them and the total of the four quarters may not be the arithmetic aggregation of the year-to-date value.
