Regulation FD regulatory
"Item 7.01 Regulation FD Disclosure"
Regulation FD is a rule that prevents company insiders, like executives, from sharing important information with some people before others get it. It matters because it helps ensure all investors have equal access to key news, making the stock market fairer and reducing chances of insider trading.
forward-looking statements regulatory
"This Report contains forward-looking statements that are made"
Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
Private Securities Litigation Reform Act of 1995 regulatory
"pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995"
Risk Factors financial
"These and other risks and uncertainties are described in additional detail in the section entitled “Risk Factors”"
Risk factors are elements or conditions that could cause an investment's value to decrease or lead to potential losses. They are like warning signs or obstacles that can affect the success of an investment, making it uncertain or more unpredictable. Recognizing risk factors helps investors understand the possible challenges and make more informed decisions.
Inline XBRL technical
"the cover page XBRL tags are embedded within the Inline XBRL document"
Inline XBRL is a file format for financial filings that embeds machine-readable data tags directly inside the human-readable report, so the same document can be read by people and parsed by software. For investors it makes extracting, comparing and verifying financial numbers faster and more reliable—like a grocery list where each item also has a barcode—reducing manual errors and speeding up analysis.

Legal Disclaimer Cautionary Statement Regarding Forward-Looking Statements This presentation, including any oral statements made regarding the contents of this presentation, contains certain statements that are not historical facts that may constitute 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, and are intended to be covered by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.

All forward-looking statements are subject to risks, uncertainties, and other factors that may cause the actual results, performance, or achievements of the Company to differ materially from any results, performance, or achievements expressed or implied by such forward-looking statements. These forward-looking statements are subject to known and unknown risks, uncertainties and other factors that could cause the actual results to differ materially from the statements, including, but not limited to: (1) deterioration in the financial performance and/or condition of borrowers of Bar Harbor Bank & Trust (the “Bank” or “BHBT”), including as a result of the negative impact of inflationary pressures on our customers and their businesses resulting in significant increases in credit losses and provisions for those losses; (2) the possibility that our asset quality could decline or that we experience greater loan losses than anticipated; (3) increased levels of other real estate owned, primarily as a result of foreclosures; (4) the impact of liquidity needs on our results of operations and financial condition; (5) competition from financial institutions and other financial service providers; (6) the effect of interest rate increases on the cost of deposits; (7) unanticipated weakness in loan demand or loan pricing; (8) adverse conditions in the national or local economies including in our markets throughout Northern New England; (9) changes in consumer spending, borrowing and saving habits; (10) the emergence and effects related to a future pandemic, epidemic or outbreak of an infectious disease, including actions taken by governmental officials to curb the spread of such an infectious disease, and the resulting impact on general economic and financial market conditions and on the Company’s and our customers' business, results of operations, asset quality and financial condition; (11) the effects of civil unrest, international hostilities or other geopolitical events, including the war in Ukraine and recent hostilities in the Middle East; (12) failure to realize the expected synergies, cost savings and other financial benefits from the acquisition of Guaranty Bancorp, Inc., the parent company of Woodsville Guaranty Savings Bank ("Woodsville"); (13) lack of strategic growth opportunities or our failure to execute on available opportunities; (14) the ability to grow and retain low-cost core deposits and retain large, uninsured deposits; (15) our ability to effectively manage problem credits; (16) our ability to successfully implement efficiency initiatives on time and with the results projected; (17) our ability to successfully develop and market new products and implement technology effectively; (18) the impact of negative developments in the financial industry and United States and global capital and credit markets; (19) our ability to retain executive officers and key employees and their customer and community relationships; (20) our ability to adapt to technological changes; (21) risks associated with litigation, including reputational and financial risks and the applicability of insurance coverage; (22) the vulnerability of the Bank’s computer and information technology systems and networks, and the systems and networks of third parties with whom the Company or the Bank contract, to unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss, and other security breaches and interruptions; (23) changes in the reliability of our vendors, internal control systems or information systems; (24) ongoing competition in the labor markets and increased employee turnover; (25) the potential impact of climate change; (26) our ability to comply with various governmental and regulatory requirements applicable to financial institutions; (27) changes in state and federal laws, rules, regulations, or policies applicable to banks or bank or financial holding companies, including regulatory or legislative developments; (28) the effects of and changes in trade and monetary and fiscal policies and laws, including the interest rate policies of the Board of Governors of the Federal Reserve System; (29) adverse impacts (including costs, fines, reputational harm, or other negative effects) from current or future litigation, regulatory examinations, or other legal and/or regulatory actions; (30) reductions in the market value or outflows of wealth management assets under management; (31) the impacts of tariffs, sanctions and other trade policies of the United States and its global trading counterparts; and (32) general competitive, economic, political, and market conditions, including economic conditions in the local markets where we operate. 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, 2025, our Quarterly Reports on Form 10-Q, 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

Accordingly, Q3 2025 figures reflect BHBT standalone. WGSB figures are included beginning in Q4 2025. 2 The increase for Q4 and Q1 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.
