Focusing on great experiences and mutually sustainable success for our clients, colleagues, and investors. Q3 2026 Earnings Supplement
2 CERTAIN IMPORTANT INFORMATION Certain comparative financial information for the three and nine months ended September 30, 2025 has been recast to reflect the Corporation's adoption of Accounting Standards Update 2025-08, Financial Services - Credit Losses (Topic 326): Purchased Financial Assets. The recast primarily eliminates the recognition of Day 1 provision expense associated with acquired loans and records an allowance for credit losses as of the acquisition date. The adoption had no impact on the economics or cash flows of the acquired assets but affected the timing of credit loss expense recognition. This change is not the result of an error, correction, or restatement of previously issued financial statements, but rather enhances comparability among periods presented in accordance with applicable financial reporting guidance. Accordingly, certain comparative amounts presented herein differ from those previously reported. CAUTION REGARDING FORWARD LOOKING STATEMENTS This presentation includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, with respect to the Corporation’s financial condition, liquidity, results of operations, future performance and business. These forward-looking statements are intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995. Forward-looking statements are those that are not historical facts. Forward-looking statements include statements with respect to beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions that are subject to significant risks and uncertainties and are subject to change based on various factors (some of which are beyond the Corporation’s control).

Such known and unknown risks, uncertainties and other factors that could cause the actual results to differ materially from the statements, include, but are not limited to, (i) adverse changes or conditions in capital and financial markets, including actual or potential stresses in the banking industry; (ii) changes in interest rates; (iii) the credit risks of lending activities, including our ability to estimate credit losses and the allowance for credit losses, as well as the effects of changes in the level of, and trends in, loan delinquencies and write-offs; (iv) effectiveness of our data security controls in the face of cyber attacks and any reputational risks following a cybersecurity incident; (v) changes in general business, industry or economic conditions or competition; (vi) changes in any applicable law, rule, regulation, policy, guideline or practice governing or affecting financial holding companies and their subsidiaries or with respect to tax or accounting principles or otherwise; (vii) adverse economic effects from international trade disputes, including threatened or implemented tariffs imposed by the U.S. and threatened or implemented tariffs imposed by foreign countries in retaliation, or similar events impacting economic activity; (viii) higher than expected costs or other difficulties related to integration of combined or merged businesses; (ix) the effects of business combinations and other acquisition transactions, including the inability to realize our loan and investment portfolios; (x) changes in the quality or composition of our loan and investment portfolios; (xi) adequacy of loan loss reserves; (xii) increased competition; (xiii) loss of certain key officers; (xiv) deposit attrition; (xv) rapidly changing technology; (xvi) unanticipated regulatory or judicial proceedings and liabilities and other costs; (xvii) changes in the cost of funds, demand for loan products or demand for financial services; and (xviii) other economic, competitive, governmental or technological factors affecting our operations, markets, products, services and prices.

The forward-looking statements contained in this presentation are based upon management’s beliefs and assumptions and are made as of the date of this presentation. Factors or events that could cause the Corporation’s actual results to differ may emerge from time to time, and it is not possible for the Corporation to predict all of them. The Corporation undertakes no obligation to publicly update or revise any forward-looking statements included in this presentation or to update the reasons why actual results could differ from those contained in such statements, whether as a result of new information, future events or otherwise, except to the extent required by law. In light of these risks, uncertainties and assumptions, the forward-looking events discussed in this presentation might not occur and you should not put undue reliance on any forward-looking statements. NON-GAAP FINANCIAL MEASURES This presentation contains references to financial measures that are not defined in GAAP. Management uses non-GAAP financial information in its analysis of the Corporation’s performance. Management believes that these non-GAAP measures provide a greater understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented. The Corporation’s management believes that investors may use these non-GAAP measures to analyze the Corporation’s financial performance without the impact of unusual items or events that may obscure trends in the Corporation’s underlying performance. This non- GAAP data should be considered in addition to results prepared in accordance with GAAP, and is not a substitute for, or superior to, GAAP results. Limitations associated with non-GAAP financial measures include the risks that persons might disagree as to the appropriateness of items included in these measures and that different companies might calculate these measures differently. Non-GAAP measures reflected within the presentation include: Return on average tangible common equity, Adjusted return on average tangible common equity, Adjusted basic earnings per common share, Adjusted diluted earnings per common share, Adjusted net income available to common shareholders, Adjusted return on average assets, Net interest margin (fully tax equivalent basis), Efficiency ratio (fully tax equivalent), Adjusted efficiency ratio (fully tax equivalent), Tangible common equity/tangible assets, Merger transaction related expenses, net of tax, Adjusted return on average equity, Tangible book value per common share.

30 INTEREST RATE SENSITIVITY (1) The graph demonstrates the annualized result of an interest rate simulation and the estimated effect that a parallel interest rate shift, or "shock," in the yield curve and subjective adjustments in deposit pricing might have on the Corporation's projected net interest income over the next 12 months. This simulation assumes that there is no growth in interest-earning assets or interest-bearing liabilities over the next 12 months. The changes to net interest income shown above are in compliance with CNB's policy guidelines.

35 NON-GAAP RECONCILIATION This presentation contains references to financial measures that are not defined in GAAP. Management uses non-GAAP financial information in its analysis of the Corporation’s performance. Management believes that these non-GAAP measures provide a greater understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented. The Corporation’s management believes that investors may use these non-GAAP measures to analyze the Corporation’s financial performance without the impact of unusual items or events that may obscure trends in the Corporation’s underlying performance. This non-GAAP data should be considered in addition to results prepared in accordance with GAAP, and is not a substitute for, or superior to, GAAP results. Limitations associated with non-GAAP financial measures include the risks that persons might disagree as to the appropriateness of items included in these measures and that different companies might calculate these measures differently. A reconciliation of these non-GAAP financial measures is provided below (dollars in thousands, except per share data).
