Non-GAAP Reconciliation: Tangible Common Equity and Tangible Assets Some of the financial measures included in this presentation are not measures of financial performance recognized by GAAP. These non-GAAP financial measures include “tangible common equity to tangible assets,” “tangible book value per share,” and “return on average tangible common equity.” Our management uses these non-GAAP financial measures in its analysis of our performance and believes these are helpful to investors as an additional tool for further understanding our performance. The following table reconciles shareholders’ equity (on a GAAP basis) to tangible common equity and total assets (on a GAAP basis) to tangible assets, calculates our tangible book value per share, and reconciles return on average tangible common equity to its most comparable GAAP measure: 17 ($ in thousands) 9/30/2025 12/31/2025 3/31/2026 6/30/2026 9/30/2026 Tangible Common Equity: Total Shareholders' Equity $ 514,335 $ 523,410 $ 531,054 $ 535,177 $ 534,243 Adjustments Goodwill $ (71,498) $ (71,498) $ (71,498) $ (71,498) $ (71,498) Core Deposit Intangible (1,495) (1,338) (1,204) (1,078) (951) Tangible Common Equity $ 441,342 $ 450,574 $ 458,352 $ 462,601 $ 461,794 Tangible Assets: Total Assets - GAAP $ 4,208,455 $ 4,208,294 $ 4,194,312 $ 4,275,002 $ 4,251,296 Adjustments Goodwill (71,498) (71,498) (71,498) (71,498) (71,498) Core Deposit Intangible (1,495) (1,338) (1,204) (1,078) (951) Tangible Assets $ 4,135,462 $ 4,135,458 $ 4,121,610 $ 4,202,426 $ 4,178,847 Common Shares Outstanding 17,043,897 17,057,397 17,074,159 16,985,919 16,827,168 Tangible Common Equity to Tangible Assets Ratio 10.67% 10.90% 11.12% 11.01% 11.05% Tangible Book Value Per Share $25.89 $26.42 $26.84 $27.23 $27.44 Average Tangible Common Equity: Average Shareholders' Equity $ 512,874 $ 519,194 $ 529,382 $ 532,409 $ 536,993 Adjustments Goodwill (71,498) (71,498) (71,498) (71,498) (71,498) Core Deposit Intangible (1,608) (1,440) (1,288) (1,161) (1,035) Average Tangible Common Equity $ 439,768 $ 446,256 $ 456,596 $ 459,750 $ 464,460 Net Income Available to Common Shareholders $ 10,148 $ 10,177 $ 11,300 $ 10,140 $ 12,637 Return on Average Tangible Common Equity 9.16% 9.05% 10.04% 8.85% 10.79% Third Quarter 2026

These non-GAAP financial measures include “pre-tax pre-provision income.” Our management uses these non-GAAP financial measures in its analysis of our performance and believes these are helpful to investors as an additional tool for further understanding our performance. This non-GAAP financial measure should not be considered a substitute for operating results determined in accordance with GAAP and may not be comparable to other similarly titled measures used by other companies. Pre-tax pre-provision income is calculated by subtracting noninterest expense from the sum of net interest income and noninterest income, as shown in the following table: Third Quarter 2026 (1) 3Q26 includes noninterest income of $2.7 million for gain on sale of office building.
