Other factors not identified above, including those described under the headings “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, our Quarterly Report on Form 10-Q filed May 8, 2025, and Current Reports on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) and available on the SEC’s website at http://www.sec.gov, may also cause actual results to differ materially from those described in our forward-looking statements. Most of these factors are difficult to anticipate and are generally beyond our control. Given these uncertainties, you are cautioned not to place undue reliance on such forward-looking statements, and you should consider these factors in connection with considering any forward-looking statements that may be made by us. We undertake no obligation to release publicly any revisions to any forward- looking statements, to report events or to report the occurrence of unanticipated events unless we are required to do so by law. 2

Legal Disclaimer Non-GAAP Financial Measures This presentation contains certain non-GAAP financial measures in addition to results presented in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These non-GAAP measures are intended to provide the reader with additional supplemental perspectives on operating results, performance trends, and financial condition. Non-GAAP financial measures are not a substitute for GAAP measures; they should be read and used in conjunction with the Company's GAAP financial information. Because non-GAAP financial measures presented in this document are not measurements determined in accordance with GAAP and are susceptible to varying calculations, these non-GAAP financial measures, as presented, may not be comparable to other similarly titled measures presented by other companies. A reconciliation of non-GAAP financial measures to GAAP measures is provided below. In all cases, it should be understood that non-GAAP measures do not depict amounts that accrue directly to the benefit of shareholders. An item which management excludes when computing non-GAAP core earnings can be of substantial importance to the Company's results for any particular quarter or year. Each non-GAAP measure used by the Company in this report as supplemental financial data should be considered in conjunction with the Company's GAAP financial information. The Company utilizes the non-GAAP measure of core earnings in evaluating operating trends, including components for core revenue and expense. These measures exclude amounts which the Company views as unrelated to its normalized operations, including gains/losses on securities, premises, equipment and other real estate owned, acquisition costs, restructuring costs, legal settlements, and systems conversion costs. Non-GAAP adjustments are presented net of an adjustment for income tax expense. The Company also calculates core earnings per share based on its measure of core earnings. The Company views these amounts as important to understanding its operating trends, particularly due to the impact of accounting standards related to acquisition activity. Analysts also rely on these measures in estimating and evaluating the Company's performance. Management also believes that the computation of non-GAAP core earnings and core earnings per share may facilitate the comparison of the Company to other companies in the financial services industry. The Company also adjusts certain equity related measures to exclude intangible assets due to the importance of these measures to the investment community. Please refer to the Appendix for more information about the non-GAAP financial measures, and reconciliations of the non-GAAP financial measures to their most directly comparable GAAP financial measures. 3

Diversification of Non-Interest Income • We have diverse sources of non-interest income that continue to be a significant contribution in any rate environment • Mortgage production is opportunistically managed between balance sheet and secondary market sales • Bar Harbor Wealth Management, along with brokerage, continues to add new customers while navigating a tumultuous market breaching $3.2 billion in AUM 16 Trust & Wealth, 40% Customer Service Fees, 41% Mortgage Banking, 3% Customer Derivative Fees, 1% Other, 15% Non-Interest Income, 1Q 2023 Trust & Wealth, 44% Customer Service Fees, 44% Mortgage Banking, 3% Other, 9% Non-Interest Income, 1Q 2024 Trust & Wealth, 44% Customer Service Fees, 40% Mortgage Banking, 5% Customer Derivative Fees 2% Other, 9% Non-Interest Income, Q1 2025

Loans – Focus on Profitability • Continue to prudently evaluate our loan portfolio mix & strategy • As of Q1 2025, Commercial Loans have increased from 53% to 71% of the Loan Portfolio since Q1 2020 17

Credit-Oriented Culture Asset Quality Remained Strong at Q1 2025 • Non-accruing loans ended the quarter at 0.26% of total loans, which was up slightly from 0.22% for Q4 2024 • Net loan charge-offs were low at $73 thousand in Q1 2025. Full year 2024 net loan charge offs totaled $353 thousand. 18 • Loans 30 days past due at 3/31/2025 were 0.53% of total loans, compared to 0.65% at 12/31/2024 • Q1 2025 Allowance for Credit Losses for Loans was down slightly from Q4 and remains well funded at 0.92% of total loans. Q1 ACL for Loans was 348% of non-accruing loans. • Pass-rated loans ratio of 96%, with positive external feedback from independent Loan Review Delinquent & Non-performing Loans / Total Loans 1 The increase for Q4 2024 and Q1 2025 was primarily a function of timing given the 31st day lands on a business day and a group of customers typically make payments about 30 days in arrears which become reportable as overdue. Accordingly, we do not believe the increase was an indication of deteriorated credit quality.

Commercial Real Estate – Office Exposure Office portfolio remains sound amid industry challenges Total outstanding office loans of $246 million, or ~ 7.9% of total loans, at Q1 2025 • 85% of total Office Exposure is pass-rated, with 8% rated Substandard or worse • Weighted average risk rating of 4.13 for Office, compared to 4.07 for total portfolio 19 • 95% of total office exposure within New England market area, with a focus on suburban markets • Largest office exposure is a $29MM RR3 credit, with a 61% LTV. • Exposure is spread across 57 relationships and 93 loans • Total commitments of $254 million include undrawn LOCs and SWAP exposure Commercial Real Estate – Office ($000s)

Interest Rate Sensitivity Position 23 • The Bank’s net interest income (“NII”) sensitivity is slightly asset sensitive as the bank continues to optimize its mix of higher yielding rate sensitive variable rate assets and lower yielding but less rate sensitive fixed rate assets. • Economic value of equity (“EVE”) is slightly liability sensitive, with Asset/Swap duration (2.2) and Liability duration (2.2) closely matched to minimize risk • Continue to enhance and expand our use of models within the organization, strengthening various asset/liability assumptions and testing methods
