ITEM 1A. RISK FACTORS

An investment in our common stock is subject to risks inherent to our business. The material risks and uncertainties that management believes affect us are described below. Before making an investment decision, you should carefully consider the risks and uncertainties described below, together with all of the other information included or incorporated by reference herein. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties that management is not aware of or focused on or that management currently deems immaterial may also impair our business operations. This Annual Report is qualified in its entirety by these risk factors.

If any of the events described in the risk factors should actually occur, our financial condition and results of operations could be materially and adversely affected. If this were to happen, the value of our securities could decline significantly, and you could lose all or part of your investment.

Liquidity and Interest Rate Risks

Interest rate volatility could significantly reduce our profitability.

Our earnings and cash flows are largely dependent upon net interest income. Net interest income is the difference between interest income earned on interest-bearing assets such as loans and securities and interest expense paid on interest-bearing liabilities such as deposits and borrowed funds. Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions, both domestic and foreign, demand for loans, securities and deposits, policies of various governmental and regulatory agencies. Changes in monetary policy, including changes in interest rates, fiscal policy, including expansion of U.S. federal deficit spending and resultant debt issuance, or the slope of the yield curve could influence not only the interest received on loans and securities and the amount of interest paid on deposits and borrowings, but such changes could also affect (i) the ability to originate loans and obtain deposits, (ii) the fair value of our financial assets and liabilities, and (iii) the average duration of loans and securities that are collateralized by mortgages. If the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and other investments, net interest income, and therefore earnings, could be adversely affected. Earnings could also be adversely affected if the interest rates received on loans and other investments fall more quickly than the interest rates paid on deposits and other borrowings. If interest rates decline, higher-rate loans and investments may be subject to prepayment risk, which could negatively impact our net interest margin. Conversely, if interest rates increase, loans and investment securities may be subject to extension risk, which could negatively impact our net interest margin as well.

We are required to maintain sufficient capital and adequate liquidity.

As a banking organization, our capital and liquidity are subject to regulation and supervision by banking regulators. We are required to maintain minimum levels of capital. The proportion of the Bank’s deposit account balances that exceed FDIC insurance limits may expose the Bank to enhanced liquidity risk as it relates to maintaining such levels of capital as uninsured depositors historically have been more likely to withdraw their deposits. In addition, our banking regulators could require us to maintain more and higher quality capital than previously expected. Our banking regulators could also require us to hold higher levels of short-term investments, thereby limiting our ability to invest in longer-term or less liquid assets at higher yields. The need to maintain capital and liquidity could result in our being required to take steps to increase our regulatory capital and may dilute shareholder value or limit our ability to pay dividends or otherwise return capital to our investors through stock repurchases. In addition, if we fail to maintain appropriate levels of capital or liquidity, we could become subject to formal or informal enforcement actions that may impose restrictions on our business, including limiting our lending activities or our ability to expand, requiring us to raise additional capital (which may be dilutive to shareholders) or requiring regulatory approval to pay dividends or otherwise return capital to shareholders. See Item 1. “Business—Regulation and Supervision—Capital Adequacy and Prompt Corrective Action” for additional information on capital requirements applicable to us and the Bank.

The Company’s earnings may not grow if we are unable to successfully attract core deposits and lending opportunities and execute opportunities to generate fee-based income.

The Company has experienced growth, and our future business strategy is to continue to expand. Historically, the growth of our loans and deposits has been the principal factor in our increase in net-interest income. In the event that we are unable to execute our business strategy of continued growth in loans and deposits, our earnings could be adversely impacted. The Company’s ability to continue to grow depends, in part, upon our ability to expand our market share, to successfully attract core deposits and identify loan and investment opportunities, as well as opportunities to generate fee-based income. Our ability to manage growth successfully will also depend on whether we can continue to efficiently fund asset growth and maintain asset quality and cost controls, as well as on factors beyond our control, such as economic conditions and interest-rate trends.

Wholesale funding sources may prove insufficient to replace deposits and support operations and future growth.

We must maintain sufficient funds to respond to the needs of customers. To manage liquidity, we use a number of funding sources in addition to core deposit growth, loan repayments and maturities of loans and securities. These sources include FHLB and the Federal Reserve Bank (“FRB”) advances, proceeds from the sale of securities and loans and liquidity resources at the holding company. Our ability to manage liquidity will be severely constrained if unable to maintain access to funding or if adequate financing is not available to accommodate future growth at acceptable costs. In addition, if we need to rely heavily on more expensive funding sources to support future growth, revenues may not increase proportionately to cover costs. In this case, our operating margins and profitability would be adversely affected. Additionally, any deterioration in the FHLB’s performance or financial condition may affect our ability to access funding and/or require us to deem the required investment in FHLB stock to be impaired. If we are not able to access funding through the FHLB, we may not be able to meet our liquidity needs, which could have an adverse effect on our results of operations or financial condition. Similarly, if we deem all or part of our investment in FHLB stock impaired, such action could have an adverse effect on our financial condition or results of operations.

Loss of deposits or a change in deposit mix could increase our cost of funding.

Deposits are a low cost and stable source of funding. We compete with banks and other financial institutions for deposits. Funding costs may increase if deposits are lost and we are forced to replace them with more expensive sources of funding, if customers shift their deposits into higher cost products or if we need to raise interest rates to avoid losing deposits. Higher funding costs reduce our net interest income, net interest margin, and net income.

If we are unable to access the capital markets, have prolonged net deposit outflows, or our borrowing costs increase, our liquidity and competitive position will be negatively affected.

Liquidity is essential to our business. We must maintain sufficient funds to respond to the needs of depositors and borrowers. To manage liquidity, we draw upon a number of funding sources in addition to in-market deposit growth and repayments and maturities of loans and investments. Any inability to access the capital markets, illiquidity or volatility in the capital markets, the decrease in value of eligible collateral or increased collateral requirements (including as a result of credit concerns for short-term borrowing), changes to our relationships with our funding providers based on real or perceived changes in our risk profile, prolonged federal government shutdowns, or changes in regulations or regulatory guidance, or other events could negatively affect our access to or cost of funding, affecting our ongoing ability to accommodate liability maturities and deposit withdrawals, meet contractual obligations, or fund asset growth and new business initiatives at a reasonable cost, in a timely manner and without adverse consequences. Additionally, our liquidity or cost of funds may be negatively impacted by the unwillingness or inability of the Federal Reserve Board to act as lender of last resort, unexpected simultaneous draws on lines of credit or deposits, the withdrawal of or failure to attract customer deposits, or increased regulatory liquidity, capital and margin requirements.

Although we maintain a liquid asset portfolio and have implemented strategies to maintain sufficient and diverse sources of funding to accommodate planned, as well as unanticipated, changes in assets, liabilities, and off-balance sheet commitments under various economic conditions, a substantial, unexpected, or prolonged change in the level or cost of liquidity could have a material adverse effect on us. If the cost effectiveness or the availability of supply in these credit markets is reduced for a prolonged period of time, our funding needs may require us to access funding and manage liquidity by other means. These alternatives may include generating client deposits, extending the maturity of wholesale borrowings, borrowing under certain secured borrowing arrangements, using relationships developed with a variety of fixed income investors, selling or securitizing loans, and further managing loan growth and investment opportunities. These alternative

Table of Contents

means of funding may result in an increase to the overall cost of funds and may not be available under stressed conditions, which would cause us to liquidate a portion of our liquid asset portfolio to meet any funding needs.

Our access to funds from subsidiaries may be restricted.

The Company is a separate and distinct legal entity from the Bank and its non-banking subsidiaries. The Company depends on dividends, distributions and other payments from its banking and non-banking subsidiaries to fund dividend payments on its common stock, debt service of subordinated borrowings, fund stock repurchase program and to fund strategic initiatives or other obligations. The Company’s subsidiaries are subject to laws that authorize regulatory bodies to block or reduce the flow of funds from those subsidiaries to the Company based on assertion that certain payments from subsidiaries are considered an unsafe or unsound practice, which could impede our access to funds that we may need to make payments on our obligations or dividend payments, if and when declared from time to time by our board of directors in its sole discretion out of funds legally available for that purpose.

Prepayments of loans may negatively impact our business as customers may prepay the principal amount of their outstanding loans at any time.

The speeds at which such prepayments occur, as well as the size of such prepayments, are within the customers’ discretion. Fluctuations in interest rates, in certain circumstances, may also lead to high levels of loan prepayments, which may also have an adverse impact on net interest income. If customers prepay the principal amount of their loans, and we are unable to lend those funds to other borrowers or invest the funds at the same or higher interest rates, interest income will be reduced. A significant reduction in interest income could have a negative impact on results of operations and financial condition.

Secondary mortgage market conditions may adversely affect our financial condition and earnings.

The secondary mortgage markets are impacted by interest rates and investor demand for residential mortgage loans and increased investor yield requirements for these loans. These conditions may fluctuate in the future. As a result, a prolonged period of secondary market illiquidity may reduce our loan production volumes, change loan portfolio composition, and reduce operating results. Secondary markets are affected by Fannie Mae, Freddie Mac, and Ginny Mae for loan purchases that meet their conforming loan requirements. These agencies could limit purchases of conforming loans due to capital constraints, changes in conforming loan criteria or other factors. Proposals to reform mortgage finance could affect the role of these agencies and the market for conforming loans.

The performance of our investment securities portfolio is subject to fluctuation due to changes in interest rates and market conditions, including credit deterioration of the issuers of individual securities.

Changes in interest rates can negatively affect the performance of most of our investment securities. Interest rate volatility can reduce unrealized gains or increase unrealized losses in our portfolio. Interest rates are highly sensitive to many factors including monetary policies, domestic and international economic, social and political conditions and issues, including trade disputes, global health pandemics, and other factors beyond our control. Fluctuations in interest rates can materially affect both the returns on and market value of our investment securities.

In addition, from time to time we may restructure portions of our investment securities portfolio as part of our asset liability management strategies or in response to liquidity needs, and we may incur losses, which may be material, in connection with any such restructuring. If we were to sell any of these securities before their value recovers, including as a result of asset liability management strategies or in response to liquidity needs, we would be required to recognize these losses and the recognition of those losses could materially and adversely affect our results of operations, capital and financial.

Impairment of investment securities or goodwill could result in a negative impact on our results of operations.

In assessing whether the impairment of securities is related to a deterioration in credit factors, we consider the length of time and extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability to retain the securities for a period of time sufficient to allow for any anticipated recovery in fair value in the near term.

Under current accounting standards, goodwill is not amortized but, instead, is subject to impairment tests on at least an annual basis or more frequently if an event occurs or circumstances change that reduce the fair value of a reporting unit below its carrying amount. A decline in our stock price or occurrence of a triggering event following any of its quarterly

Table of Contents

earnings releases and prior to the filing of the periodic report for that period could, under certain circumstances, require performance of a goodwill impairment test and result in an impairment charge being recorded for that period which was not reflected in such earnings release. During 2025, our annual qualitative assessment indicated that it was more likely than not that the fair value of the reporting unit exceeded its carrying value, resulting in no impairment. In a future assessment, we could conclude that all or a portion of our goodwill is impaired, which would result in a non-cash charge to earnings.

Potential downgrades of U.S. government securities by one or more of the credit ratings agencies could have a material adverse effect on our operations, earnings and financial condition.

A possible future downgrade of the sovereign credit ratings of the U.S. government and a decline in the perceived creditworthiness of U.S. government-related obligations could impact our ability to obtain funding that is collateralized by affected instruments, as well as affect the pricing of that funding when it is available. A downgrade may also adversely affect the market value of such instruments. We cannot predict if, when or how any changes to the credit ratings or perceived creditworthiness of these organizations will affect economic conditions. Such ratings actions could result in a significant adverse impact on us. Among other things, a downgrade in the U.S. government’s credit rating could adversely impact the value of our securities portfolio and may trigger requirements that we post additional collateral for trades relative to these securities. A downgrade of the sovereign credit ratings of the U.S. government or the credit ratings of related institutions, agencies or instruments could significantly exacerbate the other risks to which we are subject and any related adverse effects on the business, financial condition and results of operations.

Revenues from our wealth management business are significant to earnings.

Generating returns that satisfy customers in a variety of asset classes is important to maintaining existing business and attracting new business. Administering or managing assets in accordance with the terms of governing documents and applicable laws is also important to client satisfaction. Failure in either of the foregoing areas can expose us to liability, and result in a decrease in revenues and earnings.

Our wealth management business may be negatively affected by changes in economic and market conditions.

A decline in economic conditions, such as recession, economic downturn, and/or inflationary conditions, changes in domestic and foreign economic conditions, volatility in financial markets, and general trends in business and finance, all of which are beyond our control, could adversely impact the market value of wealth management AUM, which are primarily marketable securities, and the fee revenues derived from the management of these assets. Market volatility that results in clients liquidating investments, as well as lower asset values, can reduce the level of AUM and decrease our wealth management revenues, which could materially adversely affect our results of operations.

Credit Risks

Deterioration in local economies or real estate markets may adversely affect our financial performance, as our borrowers’ ability to repay loans and the value of the collateral securing the loans may decline.

We serve individuals and businesses located in Maine, New Hampshire, and Vermont. A substantial portion of the loan portfolio is secured by real estate in these areas and the value of the associated collateral is subject to local real estate market conditions. Furthermore, many customers in the hospitality industry rely upon a high number of tourists to vacation destinations and attractions within our markets. Our success is largely dependent on the economic conditions, including employment levels, population growth, income levels, savings trends and government policies in those market areas. A downturn in the local economies may adversely affect collateral values, sources of funds, and demand for products, all of which could have a negative impact on results of operations, financial condition and business expansion.

High concentrations of commercial loans may increase exposure to credit loss upon borrower default.

As of December 31, 2025, approximately 66% of our loan portfolio consisted of commercial real estate, commercial and industrial and construction loans. Commercial loan portfolio concentration generally exposes lenders to greater risk of delinquency and loss than residential real estate loans because repayment of the loans often depends on the successful operation and income streams from the property. Commercial loans typically involve larger balances to single borrowers or groups of related borrowers as compared to residential real estate loans. As our loan portfolio contains a significant number of large commercial loans, the deterioration of one or a few of these loans could cause a significant increase in

Table of Contents

non-performing loans, provision for loan losses, and/or an increase in loan charge-offs, all of which could adversely affect our financial condition and results of operations.

Greater than anticipated credit losses in the loan portfolios may adversely affect our earnings.

Credit losses are inherent in the business of making loans and could have a material adverse effect on operating results. We make various assumptions and judgments about the collectability of the loan portfolio and provide an ACL based on a number of factors. The ACL is evaluated on a periodic basis using current information, including the quality of the loan portfolio, economic conditions, and value of the underlying collateral and the level of non-accrual loans. Although we believe the ACL is appropriate to absorb probable losses in the loan portfolio, this allowance may not be adequate. Increases in the allowance will result in an expense for the period, thereby reducing reported net income. In addition, our regulators, as an integral part of their examination process, periodically review the allowance for credit losses on loans and may require us to increase the allowance for credit losses on loans by recognizing additional provisions for loan losses charged to income, or to charge-off loans, which, net of any recoveries, would decrease the allowance for credit losses on loans. Any such additional provisions for credit losses or charge-offs could have a material adverse effect on our financial condition and results of operation.

A portion of our loan portfolio consists of loan participations, which may have a higher risk of loss than loans we originate because we are not the lead lender and we have limited control over credit monitoring.

We occasionally purchase loan participations. Although we underwrite these loan participations consistent with our general underwriting criteria, loan participations may have a higher risk of loss than loans we originate because we are limited in our ability to monitor the performance of the loan and rely significantly on the lead lender . Moreover, our decisions regarding the classification of a loan participation and loan loss provisions associated with a loan participation are made in part based upon information provided by the lead lender. A lead lender also may not monitor a participation loan in the same manner as we would for loans that we originate. At December 31, 2025, we held loan participation interests in our commercial portfolio totaling $686 million and residential and consumer loans totaling $104 million.

We are exposed to risk of environmental liabilities with respect to properties to which we take title.

In the course of business, we may own or foreclose and take title to real estate that may be subject to environmental liabilities with respect to subject property. As a result, we may be held liable for property damage, personal injury, investigation and restoration costs. The cost associated with investigation or restoration activities could be substantial. In addition, as the owner or former owner of a contaminated site, we may be subject to common law claims by third parties based on damages and costs resulting from environmental contamination emanating from the property. We may not have adequate remedies against the prior owner or other responsible parties and could find it difficult or impossible to sell the affected properties. These events could have an adverse effect on our financial condition and results of operations.

Operational Risks

We are subject to a variety of operational risks, including reputational risk, and the risk of fraud or theft by employees or outsiders, which may adversely affect our business and results of operations.

We are exposed to many types of operational risks, including reputational risk, legal and compliance risk, the risk of fraud or theft by employees or outsiders, and unauthorized transactions by employees or operational errors, including clerical or record-keeping errors or those resulting from faulty or disabled computer or telecommunications systems. If personal, non-public, confidential, or proprietary information of customers in our possession were to be mishandled or misused, we could suffer significant regulatory consequences, reputational damage, and financial loss.

Because the nature of the financial services business involves a high volume of transactions, certain errors may be repeated or compounded before they are discovered and successfully rectified. Our necessary dependence upon automated systems to record and process transactions and its large transaction volume may further increase the risk that technical flaws or employee tampering or manipulation of those systems will result in losses that are difficult to detect. We may also be subject to disruptions of our operating systems arising from events that are wholly or partially beyond our control (e.g., computer viruses or electrical or telecommunications outages, natural disaster, pandemics, or other damage to property or physical assets), which may give rise to disruption of service to customers and to financial loss or liability. We are further exposed to the risk that our external vendors may be unable to fulfill their contractual obligations (or will be subject to the same risk of fraud or operational errors by their respective employees) and to the risk that our vendors’ business continuity

Table of Contents

and data security systems prove to be inadequate. The occurrence of any of these risks could result in a diminished ability to operate (e.g., by requiring us to expend significant resources to correct the defect), as well as potential liability to customers, reputational damage, and regulatory intervention.

In addition, we are dependent on our reputation within our market area, as a trusted and responsible financial company, for all aspects of our relationships with customers, employees, vendors, third-party service providers and others with whom we conduct business or potential future business, particularly because our business is primarily concentrated in Northern New England. Our actual or perceived failure, including, to (i) identify and address potential conflicts of interest, ethical issues, money-laundering, or privacy issues; (ii) meet legal and regulatory requirements applicable to the Bank and to the Company; (iii) maintain the privacy of customer and accompanying personal information; (iv) maintain adequate record keeping; (v) engage in proper sales and trading practices; and (vi) identify the legal, reputational, credit, liquidity and market risks inherent in our products; or any action of one of our employees that results in actual or perceived misconduct or error, among other things, could give rise to reputational risk that could cause harm to the Bank and our business prospects. If we fail to address any of these issues in an appropriate manner, we could be subject to additional legal risks, which, in turn, could increase the size and number of litigation claims and damages asserted or subject us to enforcement actions, fines and penalties and cause us to incur related costs and expenses. Because we primarily serve individuals and businesses located in Northern New England, any negative impact resulting from reputational harm, including any impact on our ability to attract and retain customers and employees, likely would be greater than if our business were more geographically diverse.

We may continue to incur substantial costs related to our acquisition of Guaranty Bancorp and the integration of Woodsville, and these costs may be greater than anticipated due to unexpected events.

We have incurred and expect to incur a number of non-recurring costs associated with the acquisition of Guaranty Bancorp, including facilities and systems consolidation costs and employment-related costs. We may also incur additional costs to maintain employee morale and to retain key employees. There are many factors beyond our control that could affect the total amount or the timing of the integration costs. Moreover, many of the additional costs that will be incurred are, by their nature, difficult to estimate accurately. These integration costs may result in the combined company taking additional charges against earnings, and the amount and timing of such charges are uncertain at present.

We may fail to realize the anticipated benefits of acquiring Guaranty Bancorp.

The success of our acquisition of Guaranty Bancorp will depend on, among other things, the ability to realize the anticipated benefits and cost savings from combining Woodsville’s business with the Bank’s business. To realize the anticipated benefits and cost savings, we must successfully integrate and combine our businesses in a manner that permits those cost savings to be realized without adversely affecting current revenues and future growth. If we are not able to successfully achieve these objectives, the anticipated benefits may not be realized fully or at all or may take longer to realize than expected. In addition, the actual cost savings of the acquisition could be less than anticipated, and integration may result in additional and unforeseen expenses.

Disruptions to our information systems and security breaches may adversely affect our business and reputation.

In the ordinary course of business, we rely on electronic communications and information systems to conduct its businesses and to store sensitive data, including financial information regarding its customers. The integrity of information systems is under significant threat from cyberattacks by third parties, including through coordinated attacks sponsored by foreign nations and criminal organizations to disrupt business operations and other compromises to data and systems for political or criminal purposes. We employ an in-depth, layered, defense approach that leverages people, processes and technology to manage and maintain cybersecurity controls. Notwithstanding the strength of defensive measures, cybersecurity threats and the tactics, techniques and procedures used in cyberattacks change, develop and evolve rapidly and continuously, including from growth in third-party services that facilitate or carry out cyberattacks and from emerging technologies, such as artificial intelligence (including machine learning and generative artificial intelligence) and quantum computing, which may be used to enhance the tactics, techniques and procedures described above and facilitate new cyber threats. Cybersecurity risks may also occur with our third-party service providers and may interfere with their ability to fulfill their contractual obligations to us, with additional potential for financial loss or liability that could adversely affect our financial condition or results of operations. We offer our customers the ability to bank remotely and provide other technology-based products and services, which services include the secure transmission of confidential information over the internet and other remote channels. To the extent that our customers’ systems are not secure or are otherwise compromised, our network

Table of Contents

could be vulnerable to unauthorized access, malicious software, phishing schemes and other security breaches. To the extent that our activities or the activities of its customers or third-party service providers involve the storage and transmission of confidential information, security breaches and malicious software could expose us to claims, regulatory scrutiny, litigation and other possible liabilities.

Information security risks have generally increased in recent years, and continue to increase, in part because of the proliferation of new technologies, the implementation of work-from-home arrangements, the use of the Internet and telecommunications technologies to conduct financial transactions, and the increased sophistication and activities of organized crime, hackers, terrorists, activists, and other external parties, some of which may be linked to terrorist organizations or hostile foreign governments. As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify or enhance our systems or to investigate and remediate vulnerabilities. System enhancements and updates may also create risks associated with implementing and integrating new systems. Due to the complexity and interconnectedness of information technology systems, the process of enhancing our systems can itself create a risk of systems disruptions and security issues.

While to date we believe that we have not experienced a significant compromise, significant data loss or material financial losses related to cybersecurity attacks, our systems and those of our customers and third-party service providers, are under constant threat and may experience a significant event in the future. We may suffer material financial losses related to these risks or be subject to liability for compromises to its customers or third-party providers. Any such losses or liabilities could adversely affect our financial condition or results of operations, and could expose us to reputation risk, the loss of client business, increased operational costs, as well as additional regulatory scrutiny, possible litigation, and related financial liability. These risks also include possible business interruption, including the inability to access critical information and systems.

Our ability to maintain our reputation is critical to the success of our business and the failure to do so may materially adversely affect our performance.

Our reputation is one of the most valuable components of our business. A key component of our business strategy is to rely on our reputation for customer service and knowledge of local markets to expand our presence by capturing new business opportunities from existing and prospective customers in our market area. We strive to conduct our business in a manner that enhances our reputation. This is done, in part, by recruiting, hiring and retaining employees who share our core values of being an integral part of the communities we serve, delivering superior service to our customers and caring about our customers and associates. If our reputation is negatively affected by the actions of our employees, by our inability to conduct our operations in a manner that is appealing to current or prospective customers, or by events beyond our control, our business and operating results may be adversely affected. The proliferation of social media websites utilized by us and other third parties, as well as the personal use of social media by our employees and others, including personal blogs and social network profiles, also may increase the risk that negative, inappropriate or unauthorized information may be posted or released publicly that could harm our reputation or have other negative consequences, including as a result of our employees interacting with our customers in an unauthorized manner in various social media outlets. Any damage to our reputation could affect our ability to retain and develop the business relationships necessary to conduct business, which in turn could negatively impact our financial condition, results of operations, and the market price of our common stock.

We have a continuing need for technological change, and we may not have the resources to implement new technology effectively, or we may experience operational challenges when implementing new technology or technology needed to compete effectively with larger institutions may not be available to us on a cost-effective basis.

The financial services industry undergoes rapid technological changes with frequent introductions of new technology-driven products and services, including developments in artificial intelligence and machine learning. In addition to serving clients better, the effective use of technology increases efficiency and enables financial institutions to reduce costs. Our future success will depend, at least in part, upon our ability to address the needs of our clients by using technology to provide products and services that will satisfy client demands for convenience, as well as to create additional efficiencies in our operations as we continue to grow and expand our products and service offerings. We offer electronic banking services for consumer and business customers via our website, including Internet banking and electronic bill payment, as well as mobile banking. We also offer debit cards, ATM cards, and automatic and ACH transfers. We may experience operational challenges as we implement these new technology enhancements or products, which could impair our ability

Table of Contents

to realize the anticipated benefits from such new technology or require us to incur significant costs to remedy any such challenges in a timely manner.

Many of our larger competitors have substantially greater resources to invest in technological improvements. We may not be as timely or successful in assessing the competitive landscape and developing or introducing new products and services as these larger competitors. Our business may be negatively impacted if we, or our third-party providers, do not timely develop and apply emerging technologies, like artificial intelligence and quantum computing, or if our initiatives in these areas are deficient or fail. Our, or our third-party providers’, inability or resistance to timely innovate or adapt operations, products and services to evolving regulatory and market environments, industry standards and consumer preferences could result in service disruptions, harm our business and adversely affect our results of operations and reputation. Third parties upon which we rely for our technology needs may not be able to develop on a cost-effective basis the systems that will enable us to keep pace with such developments. As a result, competitors may be able to offer additional or superior products compared to those that we will be able to provide, which would put us at a competitive disadvantage. We may lose clients seeking new technology-driven products and services to the extent we are unable to provide such products and services. Accordingly, the ability to keep pace with technological change is important and the failure to do so could adversely affect our business, financial condition and results of operations.

Our operations are reliant on outside vendors.

Our operations are dependent on the use of certain outside vendors for its day-to-day operations. Vendors may not perform in accordance with established performance standards required in their agreements for any number of reasons including a change in the vendor’s senior management, financial condition, product line or mix and how they support existing customers, or simply change their strategic focus putting us at risk. While we have comprehensive policies and procedures in place to mitigate risk in all phases of vendor management from selection to performance monitoring, the failure of a vendor to perform in accordance with contractual agreements could be disruptive to our business, which could have a material adverse effect on our financial condition and results of operations.

We may incur significant losses as a result of ineffective risk management processes and strategies.

We seek to monitor and control our risk exposure through a risk and control framework encompassing a variety of separate but complementary financial, credit, operational, compliance, and legal reporting systems; internal controls; management review processes; and other mechanisms. In some cases, management of our risks depends upon the use of analytical and/or forecasting models, which, in turn, rely on assumptions and estimates. If the models used to mitigate these risks are inadequate, or the assumption or estimates are inaccurate or otherwise flawed, we may fail to adequately protect against risks and may incur losses. While we believe that we have adopted appropriate management and compliance programs, compliance risks will continue to exist, particularly as we anticipate and adapt to new and evolving laws, rules and regulations and evolving interpretations by regulatory authorities. In addition there may be risks that exist, or that develop in the future, that we have not appropriately anticipated, identified or mitigated, which could lead to unexpected losses and our results of operations or financial condition could be materially adversely affected.

Our internal controls, procedures and policies may fail or be circumvented.

Management regularly reviews and updates our internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well-designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of the controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations and financial condition.

We may be adversely affected by the soundness of other financial institutions.

Our ability to engage in routine funding transactions could be adversely affected by the actions and commercial soundness of other financial institutions. Financial services companies are interrelated as a result of trading, clearing, counterparty and other relationships. Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, transactional counterparties or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. If such events were to occur again in the future and result in the receivership of financial institutions, there is no guarantee that the systemic risk exception would be invoked to allow the FDIC to complete its resolution of such financial institutions in a manner that fully protects

Table of Contents

depositors or counterparties. We have exposure to a number of different counterparties, and we routinely execute transactions with counterparties in the financial industry, including brokers and dealers, other commercial banks, investment banks, and other financial institutions. Many of these transactions expose us to credit risk in the event of default of our counterparty or customer. In addition, our credit risk may be exacerbated when the collateral held by us cannot be liquidated or is liquidated at prices not sufficient to recover the full amount of the financial instrument exposure due to us. There is no assurance that any such losses would not materially and adversely affect our results of operations.

Changes in the federal, state or local tax laws may negatively impact our financial performance and we are subject to examinations and challenges by tax authorities.

We are subject to federal and applicable state tax laws and regulations. Changes in these tax laws and regulations, some of which may be retroactive to previous periods, could increase our effective tax rates and, as a result, could negatively affect our current and future financial performance. Furthermore, tax laws and regulations are often complex and require interpretation. In the normal course of business, we are routinely subject to examinations and challenges from federal and applicable state tax authorities regarding the amount of taxes due in connection with investments we have made and the businesses in which we have engaged. Recently, federal and state taxing authorities have become increasingly aggressive in challenging tax positions taken by financial institutions. These tax positions may relate to tax compliance, sales and use, franchise, gross receipts, payroll, property and income tax issues, including tax base, apportionment and tax credit planning. The challenges made by tax authorities may result in adjustments to the timing or amount of taxable income or deductions or the allocation of income among tax jurisdictions. If any such challenges are made and are not resolved in our favor, they could have a material adverse effect on our business, financial condition and results of operations.

Strategic and External Risks

Changes and instability in economic conditions, geopolitical matters and financial markets, including a contraction of economic activity, could adversely impact our business, results of operations and financial condition.

Our success depends, to a certain extent, upon global, domestic and local economic and political conditions, as well as governmental monetary policies. Unfavorable or uncertain economic conditions can be caused by declines in economic growth, business activity, or investor or business confidence; limitations on the availability of or increases in the cost of credit and capital; increases in inflation or interest rates; uncertainties regarding fiscal and monetary policies; the timing and impact of changing governmental policies, including changes in guidance and interpretation by regulatory authorities; changes in trade policies by the U.S. or other countries, such as tariffs or retaliatory tariffs as those proposed by the new U.S. Administration; supply chain disruptions; consumer spending; employment levels; labor shortages; challenging labor market conditions; wage stagnation; federal government shutdowns; energy prices; home prices; commercial property values; bankruptcies and a default by a significant market participant or class of counterparties; natural disasters; climate change; epidemics; pandemics; terrorist attacks; acts of war; or a combination of these or other factors.

Monetary policy and economic environment could impact our financial performance.

Our earnings are significantly affected by the monetary and fiscal policies of governmental authorities, including the Federal Reserve Board. Among the instruments of monetary policy used by the Federal Reserve Board to implement these objectives are open-market operations in U.S. Government securities and federal funds, changes in the discount rate on member bank borrowings, and changes in reserve requirements against member bank deposits. These instruments of monetary policy are used in varying combinations to influence the overall level of bank loans, investments, and deposits, and the interest rates charged on loans and paid for deposits. The Federal Reserve Board frequently uses these instruments of monetary policy, especially its open-market operations and the discount rate, to influence the level of interest rates, thereby affecting the strength of the economy, the level of inflation, or the price of the dollar in foreign exchange markets. The monetary policies of the Federal Reserve Board have had a significant effect on the operating results of banking institutions in the past and are expected to continue to do so in the future. It is not possible to predict the nature of future changes in monetary and fiscal policies, or the effect which they may have on our business and earnings.

Inflation can have an adverse impact on our business and on our customers.

Inflation risk is the risk that the value of assets or income from investments will be worth less in the future as inflation decreases the value of money. The future rate of inflation and other economic factors remain uncertain, and the Federal Reserve Board may decrease or increase interest rates slower or faster than anticipated. If inflation increases and interest rates rise, the value of our investment securities, particularly those with longer maturities, will decrease, although this

Table of Contents

effect is less pronounced for floating rate instruments. Prolonged periods of inflation also may impact our profitability by negatively impacting our costs and expenses, including increasing funding costs and expenses related to talent acquisition and retention, and negatively impacting the demand for our products and services. Moreover, our customers are also affected by inflation and the rising costs of goods and services used in their households and businesses, which could have a negative impact on their ability to repay their loans. Adverse changes in inflation and interest rates could negatively impact consumer and business confidence, and adversely affect the economy as well as our business, results of operations and financial condition.

Increased market volatility and adverse changes in financial or capital market conditions may increase our market risk.

Our liquidity, competitive position, business, results of operations and financial condition are affected by market risks such as changes in interest rates, fluctuations in equity, commodity and futures prices, the implied volatility of interest rates and credit spreads and other economic and business factors. These market risks may adversely affect, among other things, the value of our securities, the cost of debt capital and our access to credit markets, the value of wealth management AUM and the fee income related to wealth management AUM, customer allocation of capital among investment alternatives, and our competitiveness with respect to deposit pricing. In times of market stress or other unforeseen circumstances, previously uncorrelated indicators may become correlated, which may limit the effectiveness of our strategies to manage these risks.

Involvement in wealth management creates risks associated with the industry.

Our wealth management operations present special risks not borne by institutions that focus exclusively on other traditional retail and commercial banking products. For example, the investment advisory industry is subject to fluctuations in the stock market and interest rate volatility that may have a significant adverse effect on transaction fees, client activity and client investment portfolio gains and losses. Also, additional or modified regulations may adversely affect our wealth management operations. In addition, our wealth management operations, are dependent on a small number of established financial advisors, whose departure could result in the loss of a significant number of client accounts. A significant decline in fees and commissions or trading losses suffered in the investment portfolio could adversely affect our income and potentially require the contribution of additional capital to support our operations.

Strong competition within our markets may significantly impact profitability.

We compete with an ever-increasing array of financial service providers. See the section entitled “Competition” in Part I. Item 1, “Business” of this Annual Report for additional competitor information. Competition from nationwide banks, as well as local institutions, continues to mount in our markets. To compete, we focus on quality customer service, making decisions at the local level, maintaining long-term customer relationships, building customer loyalty, and providing products and services designed to address the specific needs of customers. Failure to perform in any of these areas could significantly weaken our competitive position, which could adversely affect growth and profitability.

Market changes may adversely affect demand for our services and impact revenue, costs, and earnings.

Channels for servicing our customers are evolving rapidly, with less reliance on traditional branch facilities, increased use of e-commerce channels, and demand for universal bankers and other relationship managers who can service multiple product lines. We have an ongoing process for evaluating the profitability of its branch system and other office and operational facilities. The identification of unprofitable operations and facilities can lead to restructuring charges and introduce the risk of disruptions to revenues and customer relationships. We compete with larger financial institutions who are rapidly evolving their service channels and escalating the costs of evolving the service process.

Expansion, growth, and acquisitions could negatively impact earnings if not successful.

We may grow organically both by geographic expansion and through business line expansion, as well as through acquisitions. Success of these activities depends on our ability to continue to maintain and develop an infrastructure appropriate to support and integrate such growth. Success may also depend on acceptance of the Bank by customers in these new markets and, in the case of expansion through acquisitions, these factors include the long-term recruitment and retention of key personnel and acquired customer relationships. Profitability depends on whether the marginal revenue generated in the new markets will offset the increased expenses of operating a larger entity, with more staff, more locations, and more product offerings. Failure to achieve any of these success factors may have a negative impact on our financial condition and results of operations.

Future pandemics, severe weather, natural disasters, acts of war or terrorism, and other external events could significantly impact our business and the business of our customers.

Future pandemics, severe weather, natural disasters, acts of war or terrorism, and other adverse external events could have a significant impact on our ability to conduct business. Such events could affect the stability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause significant property damage, result in loss of revenue and/or cause us to incur additional expenses. In particular, such events may have a particularly negative impact upon the business of customers who are engaged in the hospitality industry in our markets, which could have a direct negative impact on our business and results of operations. Further, work-from-home and other modified business practices may introduce additional operational risks, including cybersecurity and execution risks, which may result in inefficiencies or delays, and may affect our ability to, or the manner in which we, conduct our business activities.

Changes in U.S. trade policies, including the imposition of tariffs and retaliatory tariffs, may adversely affect our business, financial condition and results of operations.

There have been significant changes to U.S. trade policies, including tariffs affecting China, Canada and Mexico and there continues to be significant discussion regarding other potential changes to U.S. trade policies, treaties and tariffs, including the potential for additional tariffs. In addition, retaliatory tariffs have been imposed and additional retaliatory tariffs are likely. Tariffs, retaliatory tariffs or other trade restrictions on products and materials that our customers import or export could cause the prices of our customers’ products to increase, which could reduce demand for such products. Any of these effects could adversely affect the ability of our customers to pay their loans. If our borrowers are unable to pay their loans, it would adversely affect our financial condition and results of operations. At this time, we are unable to predict whether and to what extent additional or higher tariffs or retaliatory tariffs will be imposed and the impact such actions will have on our customers.

Legal, Regulatory and Compliance Risks

We are subject to extensive government regulation and supervision, which may interfere with the ability to conduct business and may negatively impact our financial results.

Banking regulations are primarily intended to protect depositors’ funds, the Federal Deposit Insurance Fund and the safety and soundness of the banking system as a whole, not shareholders. These regulations affect our lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress and federal regulatory agencies continually review banking laws, regulations and policies for possible changes. We expect to become subject to future laws, rules and regulations beyond those currently proposed, adopted or contemplated in the U.S., as well as evolving interpretations of existing and future laws, rules and regulations. These and other restrictions could subject us to additional costs, limit the types of financial services and products we can offer, and/or limit the pricing we can charge on certain banking services, among other things. Compliance personnel and resources may increase costs of operations and adversely impact earnings.

We face significant legal risks, both from regulatory investigations and proceedings and from private actions brought against us.

As a participant in the financial services industry, many aspects of our business involve substantial risk of legal liability. From time to time, customers and others make claims and take legal action pertaining to the performance of our responsibilities, including our responsibilities as a fiduciary. Whether customer claims and legal action related to the performance of our responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to us, they may result in significant expenses, attention from management and financial liability. Any financial liability or reputational damage could have a material adverse effect on our business, which, in turn, could have a material adverse effect on our financial condition and results of operations. There is no assurance that litigation with private parties will not increase in the future. Actions currently pending against us may result in judgments, settlements, fines, penalties or other results adverse to us, which could materially adversely affect our business, financial condition or results of operations, or cause serious reputational harm to us.

We are subject to numerous laws designed to protect consumers, including the Community Reinvestment Act and fair lending laws, and failure to comply with these laws could lead to a wide variety of sanctions.

The CRA, the Equal Credit Opportunity Act, the Fair Housing Act, and other fair lending laws and regulations impose community investment and nondiscriminatory lending requirements on financial institutions. The CFPB, the Department

Table of Contents

of Justice and other federal agencies are responsible for enforcing these laws and regulations. A successful regulatory challenge to an institution’s performance under the CRA, the Equal Credit Opportunity Act, the Fair Housing Act or other fair lending laws and regulations could result in a wide variety of sanctions, including damages and civil money penalties, injunctive relief, restrictions on mergers and acquisitions, restrictions on expansion and restrictions on entering new business lines. Private parties may also have the ability to challenge an institution’s performance under fair lending laws in private class action litigation. Such actions could have a material adverse effect on our business, financial condition and results of operations.

We may become subject to enforcement actions even though noncompliance was inadvertent or unintentional.

The financial services industry is subject to intense scrutiny from bank supervisors in the examination process and aggressive enforcement of federal and state regulations, particularly with respect to mortgage-related practices and other consumer compliance matters, and compliance with anti-money laundering, BSA and OFAC regulations, and economic sanctions against certain foreign countries and nationals. Enforcement actions may be initiated for violations of laws and regulations and unsafe or unsound practices. We maintain systems and procedures designed to ensure that we comply with applicable laws and regulations; however, some legal/regulatory frameworks provide for the imposition of fines or penalties for noncompliance even though the noncompliance was inadvertent or unintentional and even though there was in place at the time systems and procedures designed to ensure compliance. Failure to comply with these and other regulations, and supervisory expectations related thereto, may result in fines, penalties, lawsuits, regulatory sanctions, reputation damage, or restrictions on our business.

The Federal Reserve Board may require us to commit capital resources to support the Bank.

Federal law requires that a holding company act as a source of financial and managerial strength to its subsidiary bank and to commit resources to support such subsidiary bank. Under the “source of strength” doctrine, the Federal Reserve Board may require a holding company to make capital injections into a troubled subsidiary bank and may charge the holding company with engaging in unsafe and unsound practices for failure to commit resources to a subsidiary bank. A capital injection may be required at times when the holding company may not have the resources to provide it and therefore may require the holding company to borrow the funds or raise capital. Any loans by a holding company to its subsidiary bank are subordinate in right of payment to deposits and to certain other indebtedness of such subsidiary bank. In the event of a holding company’s bankruptcy, the bankruptcy trustee will assume any commitment by the holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank. Moreover, bankruptcy law provides that claims based on any such commitment will be entitled to a priority of payment over the claims of the institution’s general unsecured creditors, including the holders of its note obligations. Thus, any borrowing that must be done by us to make a required capital injection becomes more difficult and expensive and could have an adverse effect on our business, financial condition and results of operations.

We are subject to stringent capital requirements which may adversely impact return on equity, require additional capital raises, or limit the ability to pay dividends or repurchase shares.

Federal regulations establish minimum capital requirements for insured depository institutions, including minimum risk-based capital and leverage ratios, and define “capital” for calculating these ratios. The minimum capital requirements are: (i) a common equity Tier 1 capital ratio of 4.5%; (ii) a Tier 1 to risk-based assets capital ratio of 6%; (iii) a total capital ratio of 8%; and (iv) a Tier 1 leverage ratio of 4%. The regulations also establish a “capital conservation buffer” of 2.5%, which if complied will result in the following minimum ratios: (i) a common equity Tier 1 capital ratio of 7.0%; (ii) a Tier 1 to risk-based assets capital ratio of 8.5%; and (iii) a total capital ratio of 10.5%. An institution will be subject to limitations on paying dividends, engaging in share repurchases and paying discretionary bonuses if its capital level falls below the capital conservation buffer amount. The application of these capital requirements could, among other things, require us to maintain higher capital resulting in lower returns on equity, and we may be required to obtain additional capital to comply or result in regulatory actions if we are unable to comply with such requirements.

Fee revenues from overdraft protection programs constitute a significant portion of our noninterest income and may be subject to increased supervisory scrutiny.

Revenues derived from transaction fees associated with overdraft protection programs offered to our customers represent a significant portion of its noninterest income. In response to recent increased congressional and regulatory scrutiny, and in anticipation of enhanced supervision and enforcement of overdraft protection practices in the future, certain banking organizations have begun to modify their overdraft protection programs, including by discontinuing the imposition of

Table of Contents

overdraft transaction fees. These competitive pressures, as well as any adoption by the Bank’s regulators of new rules or supervisory guidance or more aggressive examination and enforcement policies in respect of banks' overdraft protection practices, could cause it to modify programs and practices in ways that may have a negative impact on revenue and our earnings.

General Risk Factors

Changes in accounting policies or in accounting standards could materially affect our results of operations, and financial condition.

Our accounting policies and methods are fundamental to how we record and report our financial condition and results of operations. From time to time, the FASB and the SEC change the financial accounting and reporting standards or the interpretation of those standards that govern the preparation of our external financial statements. These changes could materially impact how we report our results of operations and financial condition. New or revised standards could also require retroactive application, which could result in the restatement of our prior period financial statements in material amounts.

Our financial statements are based in part on assumptions and estimates, which, if wrong, could cause unexpected losses in the future.

Pursuant to U.S. GAAP, we are required to use certain assumptions and estimates in preparing our financial statements, including in determining loan loss and litigation reserves, goodwill impairment and the fair value of certain assets and liabilities, among other items. If assumptions or estimates underlying our financial statements are incorrect, we may experience material losses.

Internal controls may become ineffective in preventing or detecting material errors.

We regularly review and update our internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the controls are met. Any failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations, and financial condition.

We may be unable to attract and retain key personnel.

Our success depends, in large part, on its ability to attract and retain key personnel. Competition for qualified personnel in the financial services industry can be intense and we may not be able to hire or retain the key personnel. In addition, the Bank’s rural geographic marketplace, combined with relatively expensive real estate purchase prices in the many tourist communities we serve, create additional risks for the our ability to attract and retain key personnel. The unexpected loss of key personnel could have an adverse impact on our business because of their skills, knowledge of the markets in which we operate, years of industry experience and the difficulty of promptly finding qualified replacement personnel.

Future capital offerings may adversely affect the market price of our common stock.

In the future, we may attempt to increase our capital resources or, if our banking subsidiaries’ capital ratios fall below required minimums, we could be forced to raise additional capital by making additional offerings of debt, common or preferred stock, trust preferred securities, and senior or subordinated notes. Upon liquidation, holders of our debt securities and shares of preferred stock and lenders with respect to other borrowings will receive distributions of our available assets prior to the holders of our common stock. Additional equity offerings may dilute the holdings of our existing stockholders or reduce the market price of our common stock, or both. Because our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. Moreover, we cannot assure you that such capital will be available to us on acceptable terms or at all. Our inability to raise sufficient additional capital on acceptable terms when needed could adversely affect our businesses, financial condition and results of operations.

The market price and trading volume of our common stock may be volatile.

The market price of our common stock may be volatile. In addition, the trading volume in our common stock may fluctuate and cause significant price variations to occur. We cannot assure you that the market price of our common stock will not

Table of Contents

fluctuate or decline significantly in the future. Some of the factors that could negatively affect our share price or result in fluctuations in the price or trading volume of our common stock include:

• quarterly variations in our operating results or the quality of our assets;

• changes in expectations as to our future financial performance;

• our past and future dividend practices;

• future sales of our equity or equity-related securities; and

Attractive acquisition opportunities may not be available to us in the future, which could limit the growth of our business.

We may not be able to sustain a positive rate of growth or expand our business. We expect that other banking and financial service companies, many of which have significantly greater resources than us, will compete with us in acquiring other financial institutions if we pursue such acquisitions. This competition could increase prices for potential acquisitions that we believe are attractive. Also, acquisitions are subject to various regulatory approvals. If we fail to receive the appropriate regulatory approvals for a transaction, we will not be able to consummate such transaction which we believe to be in our best interests. Among other things, our regulators consider our capital, liquidity, profitability, regulatory compliance and levels of goodwill and intangibles when considering acquisition and expansion proposals. Other factors, such as economic conditions and legislative considerations, may also impede or prohibit our ability to expand our market presence. If we are not able to successfully grow our business, our financial condition and results of operations could be adversely affected.

Anti-takeover provisions could negatively impact our stockholders.

Provisions of the articles of incorporation, Bylaws and applicable Maine law may delay or discourage transactions involving an actual or potential change in the Company’s control or change in its management, including transactions in which shareholders might otherwise receive a premium for their shares, or transactions that its shareholders might otherwise deem to be in their best interests. Our articles of organization authorize our Board of Directors to issue preferred stock without stockholder approval and such preferred stock could be issued as a defensive measure in response to a takeover proposal. These and other provisions could make it more difficult for a third party to acquire us.

ITEM 1B. UNRESOLVED STAFF COMMENTS.

None.

ITEM 1C. CYBERSECURITY

Introduction

Cybersecurity threats pose a risk to the Company as crimes committed through or involving the internet. Examples of those threats are malware, phishing, hacking, denial of service attacks, stealing information, unauthorized intrusions into internal systems or the systems of third-party vendors that could adversely impact operations or damage reputations. We are subject to extensive federal and state regulation of customer privacy and the security of financial information. Our federal regulator, the FDIC, is part of the Federal Financial Institutions Examination Council (FFIEC), which publishes extensive guidelines and examination procedures that are used to review the security of financial institutions.

Cybersecurity Risk Management

We utilize third party service providers to support and facilitate business and operational activities to achieve strategic goals. However, third parties may expose us and our customers to various risks. We have implemented a Vendor Risk

Table of Contents

Management (“VRM”) framework, which provides the tools and practices utilized in the oversight of third-party service providers, with an objective to meet legal and regulatory obligations, contractual requirements, performance expectations, and our own principles and values. For the 2025 period, there were no material incidents affecting the VRM framework or controls.

We have developed cybersecurity and data privacy programs designed to enable and safeguard the confidentiality, integrity and availability of our information systems and data by providing proactive security expertise and risk assessments, creating and maintaining a resilient and secure environment, and fostering a culture of security awareness and compliance throughout our organization. We maintain a robust Information Security Program that sets forth our commitment to the continual review and improvement of policies, processes, procedures, and standards for evaluating electronic and physical methods of accessing, collecting, storing, using, transmitting, disposing of, and protecting sensitive information, including customer information under guidelines established as part of the Gramm Leach-Bliley Act (GLBA).

The Bank manages cybersecurity threats proactively and maintains robust controls to protect its critical systems and data by investing in secure, reliable and resilient technology infrastructure, fostering a culture of technology risk awareness and continuously improving its technology risk management practices. Our process for monitoring and mitigating cybersecurity risk is designed in conjunction with our overall Risk Management Policy and Information Security Program. One of the key aspects of these programs are various risk assessments that are used to identify industry and company-specific risks, measure control effectiveness, identify any gaps that need to be addressed, and linking our controls with applicable policies, standards and guidelines to ensure that responsible parties are aware of their obligations with respect to this program. Annually, we engage a third party to perform penetration testing and ongoing analysis to identify potential vulnerabilities and areas for additional enhancements as well as a full-scope independent audit of IT and Information Security processes.

Risk Management Oversight and Governance

The management of cybersecurity risks is ultimately the responsibility of Company management and is governed by the Board. They devote significant time and attention to the oversight of cybersecurity and information security risks.The Board through its Board Risk Committee reviews monthly information technology and Information Security and Vendor Management reports that highlight key areas of focus and risk. The Board also reviews and approves the Information Security Program, the central program outlining cyber-security processes and controls annually and frequently receives presentations on and discusses cybersecurity and information security risks, industry trends and best practices.

Reporting to our Chief Risk Officer, our Security Information Officerhas more than 20 years of experience in the information/computer security industry. He holds a Bachelor of Science in Economic Crime Investigation, a Masters of Business Administration and several certifications including Certified Information Systems Security Professional (“CISPP”) and Certified in Risk and Information Systems Control (“CRISC”). He is supported by an experienced information security team. All of our employees also have a responsibility to protect the privacy of Company and Bank confidential and proprietary information. They are required to undergo periodic information security awareness training to ensure a clear understanding of their roles in protecting information assets and to create a security-minded culture. Additionally, the Company carries out regular phishing simulation tests throughout the year to keep employees alert, spread awareness and ensure that employees have the knowledge and resources necessary to report suspicious activity.

To date, we have not experienced a cybersecurity incident or data breach that has materially affected us or our business strategy, results of operations, or financial condition.

ITEM 2. PROPERTIES

Our Corporate Office is located at 82 Main Street in Bar Harbor, Maine. We provide full-banking services at 22 locations in Maine, 30 locations in New Hampshire and 10 locations in Vermont. We also have one stand-alone drive-up facility located in Woodstock, Vermont. In addition to banking offices, we have Operations Centers located in Ellsworth, Maine, and Newport, New Hampshire that house members of our operations, wealth management and administrative teams. We have additional office space located in a bank-owned facility in Bangor, Maine and in leased office spaces located in Hampden and Portland, Maine and in Manchester, New Hampshire. These locations offer back office support for multiple business lines and related functions throughout the organization. Additionally, we own a Wealth Management office building located in Concord, New Hampshire. In total, we own 41 retail banking branches and lease 21 others. We also own an additional 5 administrative buildings and lease 3 others. In the opinion of management, our physical properties are considered adequate to meet the needs of customers in the communities served. At December 31, 2025 the total net book value of our land, buildings, leasehold improvements, furniture, fixtures and equipment was $58.2 million.

ITEM 3. LEGAL PROCEEDINGS

We are from time to time subject to claims and litigation arising in the ordinary course of business. These claims and litigation may include, among other things, allegations of violation of banking and other applicable regulations, competition laws, labor laws and consumer protection laws, as well as claims or litigation relating to intellectual property, securities, breach of contract and tort. We intend to defend ourselves vigorously against any pending or future claims and litigation.

At this time, in the opinion of management, the likelihood is remote that the impact of such proceedings, either individually or in the aggregate, would have a material adverse effect on our consolidated results of operations, financial condition or cash flows. However, one or more unfavorable outcomes in any claim or litigation against us could have a material adverse effect for the period in which they are resolved. In addition, regardless of their merits or their ultimate outcomes, such matters are costly, divert management’s attention and may materially adversely affect our reputation, even if resolved in our favor.

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

Market Information

The common stock of the Company is traded on the NYSE American, under the trading symbol “BHB”. As of March 6, 2026, there were 16,742,104 shares of Bar Harbor Bankshares common stock, par value $2.00 per share, outstanding and approximately 1,426 shareholders of record, as obtained through the Company’s transfer agent. The number of record-holders may not reflect the number of persons or entities holding stock in nominee name through banks, brokerage firms or other nominee.

Cash dividends declared and paid totaled $0.32 per share in the second, third and fourth quarters of 2025 and $0.30 per share in the first quarter of 2025. We currently expect that comparable cash dividends will continue to be paid in the future. However, no assurances can be given that any dividends will be declared or paid on the Company’s common stock in the future, or, if declared and paid, the amount or frequency of those dividends. The ability of the Company to pay dividends is contingent on the ability of the Bank to dividend funds to the Company to finance the payment of those dividends. The ability of the Company and the Bank to pay dividends is restricted by certain laws and regulations, and the payment of dividends by the Company and the Bank is within the discretion of their respective boards of directors.

The information called for by this item under Item 201(d) of Regulation S-K related to securities authorized for issuance under our equity compensation plans is set forth in our 2026 Proxy Statement, and is incorporated herein by reference.

NON-GAAP FINANCIAL MEASURES

Our accounting and reporting policies conform to accounting principles generally accepted in the United States of America ("GAAP") and the prevailing practices in the financial services industry. However, we also evaluate our performance by reference to certain additional financial measures discussed in this Annual Report that we identify as being “non-GAAP financial measures.” In accordance with SEC rules, we classify a financial measure as being a non-GAAP financial measure if that financial measure excludes or includes amounts, or is subject to adjustments that have the effect of excluding or including amounts, that are included or excluded, as the case may be, in the most directly comparable measure calculated and presented in accordance with GAAP as in effect from time to time in the United States in our statements of income, balance sheets or statements of cash flows. Non-GAAP financial measures do not include operating and other statistical measures or ratios or statistical measures calculated using exclusively either financial measures calculated in accordance with GAAP, operating measures or other measures that are not non-GAAP financial measures or both.

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 Annual Report 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 herein. 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 financial measures 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 Annual Report as supplemental financial data should be considered in conjunction with the Company's GAAP financial information. The Company utilizes these non-GAAP financial measures for purposes of measuring our performance against our peer group and other financial institutions and analyzing our internal performance. We also believe these non-GAAP financial measures help investors better understand the Company’s operating performance and trends and allow for better performance comparisons to other banks. In addition, these non-GAAP financial measures remove the impact of unusual items that may obscure trends in the Company’s underlying performance.

The non-GAAP financial measures that we discuss in this Annual Report should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which we calculate the non-GAAP financial measures that we discuss in this Annual Report may differ from that of other companies reporting measures with similar names. You should understand how such other banking organizations calculate their financial measures similar or with names similar to the non-GAAP financial measures we have discussed in this Annual Report when comparing such non-GAAP financial measures. The following reconciliation table provides a more detailed analysis of these, and reconciliation for, each of non-GAAP financial measures.

COMPARISON OF FINANCIAL CONDITION AT DECEMBER 31, 2025 AND 2024

Cash and cash equivalents

Total cash and cash equivalents at December 31, 2025 were $80.8 million, compared to $72.2 million at December 31, 2024. Interest-earning deposits held with other banks totaled $35.9 million at year-end 2025 compared to $37.9 million at year-end 2024 carrying a yield of 4.53% in 2025 versus 5.54% in 2024.

Available-for-sale debt securities

Securities totaled $597.4 million at year-end 2025 and $521.0 million at year-end 2024. The increase is primarily due to $115.0 million in securities from the Woodsville acquisition. During 2025, security purchases totaled $91.0 million and were offset by $43.6 million in sales and $99.8 million of maturities, calls and pay-downs of amortizing securities. The sales primarily consisted of $40.8 million of lower yielding securities from the acquisition of Woodsville. Fair value adjustments decreased the security portfolio by $47.5 million in 2025 compared to a $62.3 million unrealized loss in 2024. The weighted average yield of the securities portfolio was 3.97% as of December 31, 2025 compared to 3.94% at year-end 2024. At the end of 2025, our securities portfolio had an average life of 7.1 years with an effective duration of 5.2 years and an average life of 8.5 and an effective duration of 4.8 at year-end 2024. All securities remain classified as available for sale to provide flexibility in loan funding and management of our cost of funds.

Federal Home Loan Bank stock

FHLB Stock was $11.3 million at year-end 2025, compared to $12.2 million at year-end 2024. Activity during 2025 consisted of $4.4 million acquired from Woodsville and purchases of $11.7 million offset by redemptions of $17.0 million due to paydowns of wholesale borrowings.

Loans held for sale

Loans held for sale increased to $5.3 million at year-end 2025 compared to $1.2 million at year-end 2024. The increase was driven by the interest rate environment and demand for wholesale loans. During 2025 we sold $52.4 million of loans held for sale resulting in a net gain of $724 thousand, during 2024 we sold $54.9 million of loans held for sale resulting in a net gain of $663 thousand.

Loans

Loans were $3.6 billion at year-end 2025, compared to $3.1 billion at year-end 2024. Loan growth was driven by the $413.4 million in loans acquired from Woodsville. Total commercial loans in 2025 were $2.4 billion, growing 6% on an annualized basis, excluding the impact of acquired loans, compared to $2.1 billion at year-end 2024. Commercial growth included $690.9 million in originations during the year, partially offset by payoffs and paydowns. Total residential loans increased to $1.1 billion at year-end 2025 from $888.3 million at year-end 2024, primarily as a result of $248.5 million in acquired loans. Consumer loans were $128.8 million at year-end 2025 compared to $102.2 million at year-end 2024 and included $21.4 million in loans acquired from Woodsville.

Allowance for Credit Losses on Loans

The allowance for credit losses on loans was $34.1 million at December 31, 2025 compared to $28.7 million as of December 31, 2024. The increase was primarily driven by $4.0 million in reserves on non-PCD loans and $1.6 million in reserves on PCD loans from the Woodsville acquisition. Net charge-offs were $950 thousand in 2025 compared to $353 thousand in 2024 driven by the resolution of three commercial and industrial loans. The net charge-offs to average loans ratio remains strong at 0.03% in 2025 compared to 0.01% in 2024.

Premises and Equipment

Premises and equipment increased $7.0 million at December 31, 2025 to $58.2 million compared to $51.2 million at December 31, 2024, driven by $6.6 million in acquired assets from the Woodsville acquisition. We sold $406 thousand of premises held for sale in 2025 that resulted in a gain of $189 thousand. The gain from premises held for sale was offset by the disposal of certain acquired assets resulting in a loss of $446 thousand for a net loss on premises and equipment of $257 thousand.

Table of Contents

Goodwill and Other Intangibles

Goodwill increased to $141.8 million in 2025 compared to $119.5 million at year-end 2024. During the year the Company acquired Woodsville which led to the increase in goodwill of $22.3 million. Other intangibles increased $12.5 million in 2025 driven by $14.0 million from the acquisition partially offset by amortization of $1.5 million.

Other Assets

Total other assets increased $16.6 million to $200.8 million at December 31, 2025 from $184.2 million as of December 31, 2024. The increase is driven by the cash surrender value of bank-owned life insurance income which increased $14.4 million primarily due to the acquisition of Woodsville. Deferred tax assets increased $6.6 million and was offset in part by other assets decreasing $4.4 million.

Deposits

Total deposits increased $553.6 million to $3.8 billion at the end of 2025 compared to $3.3 billion at the end of 2024. The overall increase in deposits is due to the acquisition of $531.3 million from Woodsville. Non-maturity deposits, excluding acquired deposits, increased $38.9 million during 2025 primarily due to interest-bearing demand deposits. Excluding the impact of acquired deposits, time deposits decreased $16.6 million during the year primarily due to $86.0 million in brokered deposit maturities.

Borrowings

Total borrowings decreased $21.0 million to $269.6 million at December 31, 2025 compared to $290.6 million as of December 31, 2024. Acquired FHLB borrowings totaled $98.0 million, of which $15.0 million of advances were paid off shortly after the acquisition date. Senior borrowings decreased $33.2 million during the year as loan paydowns, deposits and proceeds from the investment portfolio were utilized to decrease borrowing levels. Subordinated borrowings increased $12.2 million primarily due to $11.2 million of subordinated borrowings from the Woodsville acquisition.

Derivative Financial Instruments and Other Liabilities

Other liabilities totaled $60.4 million at December 31, 2025 compared to $66.6 million as of December 31, 2024. The decrease was primarily driven by a $10.0 million reduction in the fair value of customer loan swaps, partially offset by increased unpaid services and $2.6 million in unearned income related to contract negotiations from the Woodsville acquisition.The reserve for unfunded commitments increased $796 thousand at the end of 2025 to $3.8 million compared to $3.1 million at December 31, 2024, which are also recorded in other liabilities.

Equity

Total equity was $532.5 million at year-end 2025, compared with $458.4 million at year-end 2024. Book value per share was $31.88 as of December 31, 2025 compared with $30.00 at December 31, 2024. Upon the acquisition of Woodsville each share of Guaranty’s common stock was converted into the right to receive 1.85 shares of the Company’s common stock, with cash paid in lieu of any fractional shares. The total consideration paid by the Company was $39.2 million and in total the Company issued 1.4 million shares of its common stock.

During 2025 and 2024, the Company declared and distributed regular cash dividends on its common stock in the aggregate amounts of $20.4 million and $17.8 million, respectively. The Company’s 2025 dividend payout ratio amounted to 44%, compared with 42% in 2024. Total cash dividends paid increased 7% in 2025 and was $1.26 per share of common stock, compared with $1.18 per share of common stock in 2024.

The Company and the Bank remained well-capitalized under regulatory guidelines at period end as further described in Note 13 – Shareholders’ Equity and Earnings Per Common Share on the Consolidated Financial Statements.

COMPARISON OF OPERATING RESULTS FOR THE YEARS ENDED DECEMBER 31, 2025 AND 2024

Net Interest Income

Net interest income for 2025 was $134.5 million compared with $113.8 million in 2024. The net interest margin was 3.41% in 2025 compared to 3.15% in the prior year. The yield on earning assets totaled 5.28% at December 31, 2025 compared to 5.18% at December 31, 2024. The yield on loans was 5.53% in 2025 and 5.40% in 2024 primarily due to the acquisition of $413.4 million loans. Total loan yield growth was partially offset by a decrease in the commercial and

Table of Contents

industrial yield to 6.44% for 2025 from 6.75% in 2024 driven by the decrease in rates of adjustable-rate loans. Costs of interest-bearing deposits decreased in 2025 to 2.17% from 2.37% in 2024 while borrowing costs increased to 4.69% in 2025 from 4.40% in 2024.

Provision for Credit Losses

The provision for credit losses on loans was $4.6 million at December 31, 2025 compared to $955 thousand at December 31, 2024. The increase was due to the $4.0 million reserve on non-PCD loans as a result of the Woodsville acquisition. The provision for credit losses on available-for-sale debt securities was $636 thousand in 2025 compared to $1.2 million in 2024. The provision for available-for-sale-debt securities was due to the deterioration in scheduled interest payments and estimated future cash flows of two corporate securities in 2024.

Non-Interest Income

Non-interest income in 2025 was $34.6 million compared to $36.9 million in 2024. Trust management fees were $16.1 million in 2025 compared to $15.7 million in 2024 due to higher assets under management of $3.0 billion at year-end 2025 compared to $2.8 billion at year-end 2024. Customer service fees increased 8% to $16.0 million in 2025 from $14.8 million in 2024 driven by increased deposit balances due to the Woodsville acquisition. Customer derivative income increased $1.1 million year-over-year primarily driven by the interest rate environment and swap timing. The overall decrease was driven by the Company recognizing impairment losses of $4.6 million on available-for-sale debt securities in 2025. For further detail see Note 3 – Available-for-Sale Debt Securities on the Consolidated Financial Statements.

Non-Interest Expense

Non-interest expense increased to $117.7 million in 2025 compared to $96.0 million in 2024. The increase was primarily due to $10.6 million in acquisition, conversion and other expenses related to the Woodsville acquisition. Salaries and benefits expense increased $5.7 million to $60.5 million in 2025 mostly due to increased personnel from the acquisition. Other expenses increased $5.5 million driven by a $1.5 million increase in the provision for unfunded commitments, $742 thousand increase in occupancy and equipment and $582 thousand in amortization of other intangibles all of which are related to the acquisition of Woodsville.

Income Tax Expense

Income tax expense was $9.0 million for the year ended December 31, 2025 compared to $9.1 million for the year ended December 31, 2024. The effective tax rate was 19.6% in 2025 compared to 17.26% in 2024.

LIQUIDITY AND CASH FLOWS

Liquidity is measured by the ability to meet short-term cash needs at a reasonable cost or minimal loss. Favorable sources of liabilities are sought to maintain prudent levels of liquid assets in order to satisfy varied liquidity demands. Besides serving as a funding source for maturing obligations, liquidity provides flexibility in responding to customer initiated needs. Many factors affect the ability to meet liquidity needs, including variations in the markets served by its network of offices, its mix of assets and liabilities, reputation and credit standing in the marketplace, and general economic conditions.

The liquidity position is actively managed through target ratios established under our liquidity and funding policy. Continual monitoring of these ratios, by using historical data and through forecasts under multiple rate and stress scenarios, allows the ability to employ strategies necessary to maintain adequate liquidity. The policy is to maintain a liquidity position of at least 8% of total assets. A portion of the deposit base has been historically seasonal in nature, with balances typically declining in the winter months through late spring, during which period the liquidity position tightens.

A liquidity contingency plan is approved by the Bank’s Board of Directors. This plan addresses the steps that would be taken in the event of a liquidity crisis, and identifies other sources of liquidity available to the Company. Management believes that the level of liquidity is sufficient to meet current and future funding requirements. However, changes in economic conditions, including consumer savings habits and availability or access to the brokered deposit market could potentially have a significant impact on the liquidity position.

The existing cash and cash equivalents (including an interest-bearing deposit at the FRB Boston), securities available for sale and cash flows from operating activities will be sufficient to meet anticipated cash needs for at least the next

Table of Contents

12 months. Future working capital needs will depend on many factors, including the rate of business and revenue growth. To the extent cash and cash equivalents, securities available for sale and cash flows from operating activities are insufficient to fund future activities, the need to raise additional funds through debt arrangements or public or private debt or equity financings may be utilized. The need to raise additional funds may be needed in the event it is determined in the future to effect one or more acquisitions of banks or businesses. If additional funding is required, we may not be able to obtain debt arrangements or to effect an equity or debt financing on terms acceptable or at all.

Capital Resources

Consistent with our long-term goal of operating a sound and profitable organization, at December 31, 2025, we continue to be a “well-capitalized” financial institution according to applicable regulatory standards. Management believes this to be vital in promoting depositor and investor confidence and providing a solid foundation for future growth.

At December 31, 2025, available same-day liquidity totaled approximately $1.0 billion, including cash, borrowing capacity at FHLB and the Federal Reserve Discount Window and various lines of credit. Additional sources of liquidity include cash flows from operations, wholesale deposits, cash flow from the Company's amortizing securities and loan portfolios. At December 31, 2025, we had unused borrowing capacity at the FHLB of $259.1 million, unused borrowing capacity at the Federal Reserve of $94.0 million and unused lines of credit totaling $41.0 million.

Purchase Obligations

In the normal course of conducting our banking and financial services business, and in connection with providing products and services to our customers, a variety of traditional third-party contracts for support services have been entered into. Examples of such contractual agreements include, but are not limited to: services providing core banking systems, ATM and debit card processing, trust services software, accounting software and the leasing of T-1 telecommunication lines and other technology infrastructure supporting our network. These types of purchase obligations that will come due during 2026 is approximately $10.3 million as of December 31, 2025 which is expected to be funded by cash flows generated from our operations.

Impact of Inflation and Changing Prices

A banking organization’s assets and liabilities are primarily monetary. Changes in the rate of inflation do not have as great an impact on the financial condition of a bank as do changes in interest rates. Moreover, interest rates do not necessarily change at the same percentage as inflation. Accordingly, changes in inflation are not expected to have a material impact on the Company.

The FOMC often applies contractionary monetary policies during times of high inflation, resulting in elevated interest rates. Elevated interest rates may lower the market value of existing balance sheet assets and often result in a significant unrealized loss position. These lower market values may negatively affect the Bank’s liquidity position as it results in a lower value of the Bank’s liquid assets.

IMPACT OF NEW ACCOUNTING PRONOUNCEMENTS

Please refer to the notes on Recently Adopted Accounting Principles and Future Application of Accounting Pronouncements in Note 1 – Summary of Significant Accounting Policies of the Consolidated Financial Statements.

Table of Contents

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Note 1 – Summary of Significant Accounting Policies to our audited Consolidated Financial Statements for the year ended December 31, 2025 contains a summary of significant accounting policies. Various elements of these accounting policies, by their nature, are subject to estimation techniques, valuation assumptions and other subjective assessments. Certain assets are carried in the consolidated statements of financial condition at estimated fair value or the lower of cost or estimated fair value. Policies with respect to the methodology used to determine the allowance for credit losses is a critical accounting policy and estimate because of its importance to the presentation of our financial condition and results of operations. The critical accounting policy involves a higher degree of complexity and requires management to make difficult and subjective judgments which often require assumptions or estimates about highly uncertain matters. The use of different judgments, assumptions, and estimates could result in material differences in the results of operations or financial condition.

Allowance for credit losses on loans (the “allowance”)

The estimate of expected credit losses on collectively evaluated loans is based on relevant information about current conditions, past events, and reasonable and supportable forward-looking forecasts regarding collectability of the reported amounts. Management employs a process and methodology to estimate the allowance for credit losses (“ACL”) on collectively evaluated loans that evaluates both quantitative and qualitative components. The methodology for evaluating the quantitative component involves pooling loans into portfolio segments for loans that share similar risk characteristics. For all loan segments measured on a collective basis, the Company utilizes a discounted cash flow (“DCF”) methodology to estimate credit losses over the expected life of the loan. The DCF methodology applies the probability of default (“PD”) and the loss given default (“LGD”) assumptions over the remaining contractual life of the loan which is adjusted for prepayment speeds, curtailment rate and time to recovery assumptions to estimate a reserve for each loan. The Company uses regression models to develop the PD and LGD assumptions, which are derived primarily from segment-specific selected peers. The loss rates are adjusted by an economic forecast over the reasonable and supportable forecast period after which time they revert back to the historical mean.

Assumptions evaluated each reporting period include the probability of default and loss given default assumptions, macroeconomic forecast variables, prepayment speed assumptions, and the determination of the qualitative factors. As of December 31, 2025 management utilized National Unemployment Rate, Commercial Real Estate Price Index and House Price Index in their economic forecast. Hypothetically, if the economic forecast was deteriorated by 100bps compared to management’s base scenario the impact to the allowance would be an increase of $1.3 million. Hypothetically, if the economic forecast improved by 100bps compared to management’s base scenario, the impact to the allowance would be a decrease of $1.3 million. Hypothetically, if prepayment speeds doubled there would be a decrease to the allowance of $2.6 million. Hypothetically, if prepayment speeds were decreased by half there would be an increase to the allowance of $2.9 million.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market Risk

Market risk is the risk of loss in a financial instrument arising from adverse changes in market rates/prices, such as interest rates, foreign currency exchange rates, commodity prices and equity prices. The most significant market risk that affects us is interest rate risk. Other types of market risk do not arise in the normal course of our business activities.

The responsibility for interest rate risk management oversight is the function of the Bank’s Asset and Liability Committee, or ALCO, chaired by the Bank’s Chief Financial Officer and composed of various members of the Bank’s senior management. ALCO meets regularly to review balance sheet structure, formulate strategies in light of current and expected economic conditions, adjust product prices as necessary, implement policy, monitor liquidity, and review performance against guidelines established to control exposure to the various types of inherent risk.

Interest Rate Risk

Interest rate risk can be defined as an exposure to movement in interest rates that could have an adverse impact on the Bank's net interest income. Interest rate risk arises from the imbalance in the re-pricing, maturity and/or cash flow

Table of Contents

characteristics of assets and liabilities. Management’s objectives are to measure, monitor and develop strategies in response to the interest rate risk profile inherent in the Bank’s balance sheet. The objectives in managing the Bank's balance sheet are to preserve the sensitivity of net interest income to actual or potential changes in interest rates, and to enhance profitability through strategies that promote sufficient reward for understood and controlled risk.

The Bank’s interest rate risk measurement and management techniques incorporate the re-pricing and cash flow attributes of balance sheet and off-balance sheet instruments as each relate to current and potential changes in interest rates. The level of interest rate risk, measured in terms of the potential future effect on net interest income, is determined through the use of modeling and other techniques under multiple interest rate scenarios. Interest rate risk is evaluated in depth on a quarterly basis and reviewed by ALCO and the Bank’s Board of Directors.

The Bank's Asset Liability Management Policy, approved annually by the Bank’s Board of Directors, establishes interest rate risk limits in terms of variability of net interest income under rising, flat, and decreasing rate scenarios. It is the role of the ALCO to evaluate the overall risk profile and to determine actions to maintain and achieve a posture consistent with policy guidelines.

Interest Rate Sensitivity Modeling:

The Bank utilizes an interest rate risk model widely recognized in the financial industry to monitor and measure interest rate risk. The model simulates the behavior of interest income and expense for all balance sheet and off-balance sheet instruments, under different interest rate scenarios together with a dynamic future balance sheet. Interest rate risk is measured in terms of potential changes in net interest income based upon shifts in the yield curve.

The interest rate risk sensitivity model requires that assets and liabilities be broken down into components as to fixed, variable, and adjustable interest rates, as well as other homogeneous groupings, which are segregated as to maturity and type of instrument. The model includes assumptions about how the balance sheet is likely to evolve through time and in different interest rate environments. The model uses contractual re-pricing dates for variable products, contractual maturities for fixed rate products, and product-specific assumptions for deposit accounts, such as money market accounts, that are subject to re-pricing based on current market conditions. Re-pricing margins are also determined for adjustable rate assets and incorporated in the model. Investment securities and borrowings with option provisions are examined on an individual basis in each rate environment to estimate the likelihood of exercise. Prepayment assumptions for mortgage loans are calibrated using specific Bank experience while mortgage-backed securities are developed from industry standard models of prepayment speeds, based upon similar coupon ranges and degree of seasoning. Cash flows and maturities are then determined, and for certain assets, prepayment assumptions are estimated under different interest rate scenarios. Interest income and interest expense are then simulated under several hypothetical interest rate conditions.

The simulation models a parallel and pro rata shift in rates over a 12-month period. Using this approach, we are able to produce simulation results that illustrate the effect that both a gradual “rate ramp” and a “rate shock” have on earnings expectations. Our net interest income sensitivity analysis reflects changes to net interest income assuming no balance sheet growth and a parallel shift in interest rates. All rate changes were “ramped” over the first 12-month period and then maintained at those levels over the remainder of the simulation horizon. Changes in net interest income based upon these simulations are measured against the flat interest rate scenario.

As of December 31, 2025, interest rate sensitivity modeling results indicate that the Bank’s balance sheet was asset sensitive over the one- and two-year horizons.

The following table presents the changes in sensitivities on net interest income for the periods ended December 31, 2025 and 2024:

(in thousands, except ratios) $ Change % Change $ Change % Change

At December 31, 2025

At December 31, 2024

Assuming short-term and long-term interest rates decline 200 basis points from current levels (i.e., a parallel yield curve shift) over the next twelve months and the Bank’s balance sheet structure and size remain at current levels, management believes net interest income will deteriorate over the one year horizon while deteriorating further from that level over the two-year horizon.

Assuming short-term and long-term interest rates increase 200 basis points from current levels (i.e., a parallel yield curve shift) over the next twelve months and the Bank’s balance sheet structure and size remain at current levels, management believes net interest income will improve over the one year horizon while improving further from that level over the two-year horizon.

As compared to December 31, 2024, asset sensitivity in year one is higher in up rate scenarios but slightly lower in down rate scenarios, while in year two, sensitives are higher in both up and down rate scenarios.

The preceding sensitivity analysis does not represent a forecast and should not be relied upon as being indicative of expected operating results. These hypothetical estimates are based upon numerous assumptions including: the nature and timing of interest rate levels and yield curve shape, prepayment speeds on loans and securities, deposit rates, pricing decisions on loans and deposits, reinvestment or replacement of asset and liability cash flows, and renegotiated loan terms with borrowers. While assumptions are developed based upon current economic and local market conditions, we cannot make any assurances as to the predictive nature of these assumptions including how customer preferences or competitor influences might change.

As market conditions vary from those assumed in the sensitivity analysis, actual results may also differ due to: prepayment and refinancing levels deviating from those assumed; the impact of interest rate changes, caps or floors on adjustable rate assets; the potential effect of changing debt service levels on customers with adjustable rate loans; depositor early withdrawals and product preference changes; and other such variables. The sensitivity analysis also does not reflect additional actions that the Bank’s Senior Executive Team and Board of Directors might take in responding to or anticipating changes in interest rates, and the anticipated impact on the Bank’s net interest income.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheet of Bar Harbor Bankshares and Subsidiaries (the "Company") as of December 31, 2025, the related consolidated statements of income, comprehensive income (loss), changes in shareholders’ equity, and cash flows for the year ended December 31, 2025, and the related notes (collectively referred to as the "financial statements"). We also have audited the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025, and the results of its operations and its cash flows for the year ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO.

Basis for Opinions

The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audit of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies

Table of Contents

and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Allowance for Credit Losses on Collectively Evaluated Loans

As discussed in Note 1 and Note 4 to the consolidated financial statements, the Company’s allowance for credit losses totaled $34.1 million as of December 31, 2025, which is primarily related to loans evaluated on a collective basis. The estimate of expected credit losses on collectively evaluated loans is based on relevant information about current conditions, past events, and reasonable and supportable forward-looking forecasts regarding collectability of the reported amounts. Management employs a process and methodology to estimate the allowance for credit losses (“ACL”) on collectively evaluated loans that evaluates both quantitative and qualitative components. The methodology for evaluating the quantitative component involves pooling loans into portfolio segments for loans that share similar risk characteristics.

For all loan segments measured on a collective basis, the Company utilizes a discounted cash flow (“DCF”) methodology to estimate credit losses over the expected life of the loan. The DCF methodology applies the probability of default (“PD”) and the loss given default (“LGD”) assumptions over the remaining contractual life of the loan which is adjusted for prepayment speeds, curtailment rate and time to recovery assumptions to estimate a reserve for each loan. The Company uses regression models to develop the PD and LGD assumptions, which are derived primarily from segment-specific selected peers. The loss rates are adjusted by an economic forecast over the reasonable and supportable forecast period after which time they revert back to the historical mean.

For all loan segments, the quantitative loss rates are supplemented by qualitative factors reflecting management’s view of how losses may vary from those represented by quantitative loss rates. Qualitative factors are applied to each portfolio segment to reflect management’s estimate of expected changes in current conditions at the balance sheet date relative to historical performance.

We identified auditing the ACL on collectively evaluated loans as a critical audit matter because there is a high degree of measurement uncertainty due to the volume of data inputs and assumptions needed to perform the quantitative calculation as well as management judgement in deriving qualitative factors. This resulted in significant auditor judgment and audit effort in evaluating the appropriateness of the data inputs and assumptions used in the DCF methodology, as well as the reasonableness of qualitative factors applied in the ACL calculation.

The primary procedures we performed to address this critical audit matter included:

Testing the design and operating effectiveness of controls over the ACL on collectively evaluated loans, including controls addressing:
