Item 1A. Risk Factors

An investment in the Company involves risk, which could be substantial. Market, liquidity, credit, operational, legal, compliance and strategic risks are inherent in our business. The material risks and uncertainties that management believes affect the Company are described below. Any of the following risks could affect the Company’s financial condition and results of operations and could be material and/or adverse in nature. You should consider all of the following risks together with all of the other information in this Annual Report on Form 10-K.

Economic and Market Conditions Risk

Our financial condition and results of operations have been adversely affected, and in the future may be adversely affected, by the U.S. and international financial market and economic conditions.

We have been, and in the future may be, affected by general business and economic conditions in the U.S. and, to a lesser extent, abroad. These conditions include short-term and long-term interest rates, inflation, money supply, political issues, legislative and regulatory changes, fluctuations in both debt and equity capital markets, broad trends in industry and finance, unemployment, investor confidence and customer deposit behavior, all of which are beyond our control. These conditions can change suddenly and negatively. In addition, volatility due to failures of other banks or general uncertainty regarding the health of banks may affect customer deposit behavior and cause deposit withdrawals, even if we are not experiencing the same uncertainty. Future changes in any of these conditions, whether related to pandemic, geopolitical conflict, the threat or occurrence of a U.S. sovereign default or government shutdown, a downgrade, or perceived future downgrade, in the U.S. sovereign credit rating or outlook, disruptions in the financial services industry or other future events that we are unable to predict, could result in increases in loan delinquencies and non-performing assets, decreases in loan collateral values, the value of our investment portfolio and demand for our products and services or otherwise adversely affect our financial condition or results of operations.

In addition, volatility and uncertainty related to inflation and its effects may contribute to or enhance some of the risks described in this section. For example, higher inflation has in the past reduced, and could in the future reduce, demand for our products, adversely affect the creditworthiness of our borrowers or result in lower values for our interest-earning assets and investment securities. Any of these effects, or others that we are not able to predict, could adversely affect our financial condition or results of operations.

Fluctuations in market interest rates have in the past adversely affected, and may in the future adversely affect, our performance.

Our profitability depends to a large extent upon our net interest income, which is the difference between interest income earned from loans and investments and the interest expense paid on deposits and borrowings. Net interest income is our largest source of revenue and can be affected significantly by changes in market interest rates, including in the shape of the yield curve or in spreads between different market interest rates, as well as by changes related to inflation. In particular, changes in relative interest rates may reduce our net interest income as the difference between interest income and interest expense decreases. As a result, we have adopted asset and liability management policies to minimize the potential adverse effects of changes in interest rates on net interest income, primarily by altering the mix and maturity of loans, investments and funding sources. See Item 7. “Management’s Discussion and Analysis—Risk Management Policies—Interest Rate Risk” for additional information regarding the Company’s asset and liability management policies and practices, as well as its interest rate risk position, including assumptions used in determining such, as of December 31, 2025. There is risk that any change in interest rates could negatively affect our results of operations or financial condition. Because market interest rates may change by differing magnitudes and at different times, significant changes in interest rates over an extended period of time could reduce overall net interest income.

In addition, volatility in interest rates can result in customer deposits flowing away from financial institutions into direct investments, and a prolonged high-interest rate environment may cause the Bank to experience increased deposit migration. This may cause the Bank to lose some of its low-cost deposit funding or could adversely affect the Bank’s operations and liquidity. Customers may also continue to move non-interest-bearing deposits into interest-bearing accounts, thereby increasing our overall deposit costs. Higher funding costs may continue to reduce our net interest margin and net interest income.

Volatility in interest rates can also result in customer deposits flowing away from financial institutions into direct investments. Direct investments, such as U.S. government and corporate securities and other investment vehicles (including money market mutual funds), generally pay higher rates of return than financial institutions because of the absence of federal

insurance premiums, and a prolonged high-interest rate environment may cause the Bank to experience increased deposit migration. This may cause the Bank to lose some of its low-cost deposit funding or could adversely affect the Bank’s operations and liquidity. Customers may also continue to move non-interest-bearing deposits into interest-bearing accounts, thereby increasing our overall deposit costs. Higher funding costs may continue to reduce our net interest margin and net interest income.

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 has been recent significant change to U.S. trade policies, including tariffs affecting numerous countries, as well as the imposition of retaliatory tariffs against the United States, 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. 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. For example, tariffs on Canadian imports could negatively affect a number of industries in Maine, and therefore our customers. In addition, if prices of consumer goods increase materially due to tariffs or other trade policy, the ability of individual households to pay their mortgages and other debt may be affected negatively. 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. This uncertainty complicates business planning for our customers in certain industries, and any resulting changes in our customers’ spending and borrowing patterns in response to this uncertainty could have an adverse effect on our business and results of operations.

We could be adversely affected by the actions or commercial soundness, strength or stability of other financial institutions.

Actual or perceived issues with, or rumors or questions about, one or more financial institutions, or the financial services industry more generally, have led to, and may in the future lead to, market-wide liquidity problems; rapid and significant deposit withdrawals at certain banks, particularly those with elevated levels of uninsured deposits; losses or defaults by certain institutions, up to and including failures of certain banks; and significant volatility in the stock of financial services institutions. In addition, our ability to engage in routine funding and settlement transactions could be adversely affected by any of these events or by other events that affect the commercial soundness of other financial institutions. Failures of one or more banks that are unrelated to the Bank may in the future increase the Bank’s deposit insurance assessments, and customers and others may seek to make comparisons between failed or failing banks and the Bank, which, even if unfounded, can spread quickly through social media or other online channels. Such comparisons could affect customer confidence in the Bank and lead to deposit withdrawals or other negative effects we are unable to predict, any of which could materially and negatively affect our results of operations and financial condition.

Financial services institutions are interrelated as a result of trading, clearing, counterparty and other relationships. We maintain a diversified securities portfolio and have exposure to many different counterparties, and we routinely execute transactions with counterparties in the financial services industry. As a result, defaults by, or even rumors or questions about, the soundness, strength or stability of one or more financial services institutions, or the financial services industry generally, could lead to losses or defaults by us or by other institutions and organizations. Many of these transactions expose us to credit risk in the event of default of our counterparty or client. Furthermore, 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. Any such losses could materially and adversely affect our results of operations.

In addition, if a counterparty should default, become insolvent, declare bankruptcy, or otherwise cease to exist, the value of our investment securities may be impaired. This could result in provision for credit losses or realized losses being charged against future income. Given the significant judgments involved, there is risk that material provisions may be recorded to establish an allowance for credit losses resulting in realized losses.

Camden National Wealth Management may be negatively affected by changes in economic and market conditions.

A substantial portion of income from fiduciary services is dependent on the market value of wealth management assets under management, which are primarily marketable securities. 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 these assets and the fee revenues derived from the management of these assets.

Continued market volatility has impacted, and may in the future impact, our business and the value of our common stock.

Our business performance and the trading price of shares of our common stock have in the past, and may in the future be, affected by many factors, including volatility in the credit, mortgage and housing markets, fluctuations in interest rates (including in response to inflation), the markets for securities relating to mortgages or housing, and the value of debt and mortgage-backed and other securities that we hold in our investment portfolio. Government action and legislation may also impact us and the value of our common stock. We cannot predict what impact, if any, future volatility will have on our business or share price.

In addition, the value of securities, derivatives and other financial instruments which we own can be affected materially by market volatility. Volatility, illiquid market conditions or other disruptions in the financial markets may make it difficult to value certain financial instruments. Valuations of financial instruments in future periods may result in significant changes in the value of financial instruments we own. At the time of any disposition of such financial instruments, the price that we realize will depend on the demand and liquidity in the market at that time and may be materially lower than their current fair value. Any of these factors could cause a decline in the value of financial instruments that we own, which may have an adverse effect on our results of operations. In addition, losses in the value of our investment securities or loan portfolio could affect market perception of us and create volatility in our stock price. Losses in the value of our investment securities, even if they do not affect earnings or capital, could also cause some depositors, particularly those who maintain uninsured and uncollateralized deposits, to question the stability of the Bank and to move their deposits away from the Bank. Such events could negatively affect our liquidity, financial condition and results of operations.

Credit Risk and Lending Business Risk

Our loans are concentrated in certain areas of Northern New England and adverse conditions in those markets could adversely affect our operations.

Prior to 2025, we primarily served individuals and businesses located in the state of Maine, with 68% of our loan portfolio concentrated among borrowers in Maine as of December 31, 2024, with higher concentrations of exposure in Cumberland, Kennebec, Knox and York counties. Although our loan portfolio became more geographically diverse following our acquisition of Northway, our loan portfolio remains significantly concentrated among Northern New England borrowers, with over 50% still located in Maine. Because a substantial portion of the loan portfolio is secured by real estate in this area, the value of the associated collateral is also subject to regional real estate market conditions. Adverse economic, political or business developments or natural hazards, the severity and frequency of which are increasing as a result of climate change, may affect these areas and the ability of property owners in these areas to make payments of principal and interest on the underlying mortgages. If these regions experience adverse economic, political or business conditions, such as prolonged elevated inflation and interest rates, or if they experience a pandemic or similar event, we likely would have higher rates of loss and delinquency on these loans than if the loans were more geographically diverse. In addition, adverse economic, political or other events may affect certain industries in our markets more than others. For example, the COVID-19 pandemic adversely affected, and future pandemics may affect, hospitality, transportation and commercial real estate industries in Maine. Negative effects on those industries could result in higher rates of loss and delinquency on our loans, which could have a material, adverse effect on our financial condition or results of operations.

Our loan portfolio includes commercial real estate and commercial loans, which are generally riskier than other types of loans.

At December 31, 2025, our commercial real estate and commercial loan portfolios comprised 52% of our total loan balances. Commercial loans generally carry larger loan balances and involve a higher risk of nonpayment or late payment than residential mortgage loans. Commercial loans may lack standardized terms and may include a balloon payment feature. The ability of a borrower to make or refinance a balloon payment may be affected by a number of factors, including the financial condition of the borrower, prevailing economic conditions and prevailing interest rates, and rising interest rates may make it more difficult or impossible for borrowers to refinance maturing loans. Repayment of these loans is generally more dependent on the economy and the successful operation of a business. High vacancy rates in commercial properties have affected, and in the future may affect, the value of commercial real estate, including by causing the value of properties securing commercial real estate loans to be less than the amounts owed on such loans. Beca use of the risks associated with commercial loans, we may experience higher rates of default, and other risks described above may be more pronounced, than if the portfolio were more heavily weighted toward residential mortgage loans. Higher rates of default or other events could cause us to experience higher credit losses or could otherwise have an adverse effect on our financial condition and results of operations.

Refer to “—Financial Condition—Loans” for additional information regarding concentrations within our commercial loan portfolio. Risks of higher credit losses and other risks described above that could result from adverse economic or other events affecting any industry within our commercial loan portfolio may be exacerbated by industry concentrations within the commercial loan portfolio.

If our allowance for credit losses for loans is not adequate to cover actual loan losses, our earnings could decrease.

We make various assumptions and judgments about the collectability of our loan portfolio and provide an allowance for credit losses for these loans (herein referred to as the “allowance for loan losses”) based on a number of factors. The level of the allowance for loan losses reflects management's continuing evaluation of industry concentrations, specific credit risks, credit loss experience, current loan portfolio quality, current economic trends and conditions, reasonable and supportable forecasts about the future, changes in competitive, legal, and regulatory conditions, and unidentified losses inherent in the current loan portfolio. Determination of the allowance for loan losses is inherently subjective because it requires significant estimates and management judgment of credit risks and future trends, which are subject to material changes. If our assumptions are incorrect, the allowance for loan losses may not be sufficient to cover the losses we could experience, which would have an adverse effect on operating results, and may also cause us to increase the allowance for loan losses in the future. Deterioration in economic conditions affecting borrowers, new information regarding existing loans, identification of additional problem loans, changes in accounting principles, and other factors, both within and outside our control, may require an increase in the allowance for loan losses. In addition, bank regulators periodically review our allowance for loan losses and may require us to increase our provisions for credit losses or recognize further loan charge-offs. Any increase in our allowance for loan losses or loan charge-offs as required by regulatory authorities could have a material adverse effect on our consolidated results of operations and financial condition. If additional amounts are provided to the allowance for credit losses, our earnings could decrease.

Prepayments of loans may negatively impact our business.

Generally, our customers may prepay the principal amount of their outstanding loans at any time, frequently without financial penalty to the borrower. The speeds at which such prepayments occur, as well as the size of such prepayments, are within our customers’ discretion. Fluctuations in interest rates, in certain circumstances, may also lead to high levels of loan prepayments. 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 our results of operations and financial condition.

Competitive and Strategic Risk

We experience strong competition within our industry and markets, which may impact our profitability and adversely affect the price of our common stock.

Competition in the banking and financial services industry is strong. In our market areas, we compete for loans, deposits and other financial products and services with large financial companies, local independent banks, thrift institutions, savings institutions, mortgage brokerage firms, credit unions, finance companies, mutual funds, insurance companies, brokerage and investment banking firms, and other financial intermediaries that offer similar services. Some of these competitors have substantially greater resources and lending limits than those of the Bank and may offer services that the Bank does not or cannot provide. Some of our non-bank competitors are not subject to the same extensive regulations we are, and, as a result, may be able to compete more effectively for business. In particular, the activity of non-bank lenders and other financial technology companies (“fintechs”) has grown significantly over recent years and is expected to continue to grow. Fintechs have offered and may continue to offer bank or bank-like products. For example, a number of fintechs have applied for, and in some cases received, bank, non-depository national bank or industrial loan charters. Under the current administration, certain U.S. banking regulators have processed charter applications on an accelerated timeline, including applications filed by fintechs. In addition, other fintechs have partnered with existing banks to allow them to offer deposit and loan products to their customers. Regulatory changes may also make it easier for fintechs to partner with banks and offer deposit products, or increase the ability of fintechs to compete through the use of non-banking products such as cryptocurrency or alternative payment systems. In July 2025, President Trump signed into law the “Guiding and Establishing National Innovation for U.S. Stablecoins Act” or the “GENIUS Act.” The GENIUS Act establishes a regulatory framework for “payment stablecoins” and their issuers. Consumers and businesses may view payment stablecoins as a substitute for traditional bank deposits, which could result in deposit withdrawals and increased competition with the Bank’s deposit products. The GENIUS Act requires the Treasury Department and federal and state regulators to issue regulations on numerous topics to interpret and implement the statute. The effect of the GENIUS Act on the Company and the Bank will depend on the final form of any regulations and cannot be predicted at this time. There is also increased competition by out-of-market competitors through online and mobile channels. Our long-term success depends on our ability to compete successfully with other financial institutions and fintechs. Because we maintain a

smaller staff and have fewer financial and other resources than larger institutions with which we compete, we may be limited in our ability to attract customers. If we are unable to attract and retain customers, we may be unable to achieve growth in the loan and core deposit portfolios, and our results of operations and financial condition may be negatively affected.

In addition, return on shareholders’ equity and other measures of profitability, which affect the market price of our common stock, depend in part on continued growth and expansion. The ability to generate internal growth is affected by the competitive factors described herein as well as by the primarily rural characteristics and related demographic features of the markets we serve. If we are unable to compete or grow effectively in our markets, it could adversely affect our business and the price of our common stock.

Market changes may adversely affect pricing of, and demand for, our services and impact results of operations.

Channels for servicing our customers are evolving rapidly, with less reliance on traditional branches, more use of online and mobile banking, and increased demand for universal bankers and other relationship managers who can service multiple product lines. We compete with larger providers that are rapidly evolving their service offerings, thereby escalating the costs of evolving the Bank’s efforts to keep pace. We have a process for evaluating the profitability of our branches 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.

In addition, our success depends, in part, on our ability to adapt products and services to changing industry standards. There is increasing pressure to provide products and services at lower prices. Lower prices can reduce our net interest margin and revenues from fee-based products and services. The adoption of new or emerging technologies, such as blockchain and artificial intelligence, or further developments in current technologies may require us to make substantial expenditures to modify or adapt our existing products and services to remain competitive. These and other capital investments in our businesses may not produce expected growth in earnings anticipated at the time of the expenditure. We might not be successful in developing or introducing new products and services, adapting to changing customer preferences and spending and saving habits (which may be altered significantly and suddenly), achieving market acceptance of our products and services, or sufficiently developing and maintaining loyal customer relationships.

Sustainability-related topics as well as companies’ actions and initiatives on such issues, have received significant attention from a wide range of stakeholders. The U.S. federal government, U.S. states and certain other countries and regions have adopted or are considering legislation, regulation or policies on these topics. Compliance with such laws, regulations or policies, including any that may be adopted in the future, could, among other things, increase the costs of operating our businesses, reduce the demand for our products and services and impact the prices we charge our customers, any or all of which could adversely affect our results of operations. In addition, policymakers in some jurisdictions have adopted or proposed laws, regulations and policies that diverge from, or potentially conflict with, those in other jurisdictions. Failure to comply with any legislation, regulation or policy, including as a result of making good faith interpretations that may differ from those taken by enforcement authorities in relevant jurisdictions, could potentially result in substantial fines, criminal sanctions, damage to the Company’s brand or operational changes. Moreover, our customers, stockholders, employees and other stakeholders have diverse expectations, demands and perspective on these topics, which are continuing to evolve. We may not be able to meet the diverse expectations and demands of all our stakeholders, which could harm our brand, reduce customer demand for our products and services, and subject us to legal and operational risks.

Camden National Wealth Management faces intense competition in attracting and retaining clients.

Due to strong competition, Camden National Wealth Management may not be able to attract and retain clients at current levels. Competition is strong as there are numerous well-established and successful investment management and wealth advisory firms including commercial banks and trust companies, investment advisory firms, mutual fund companies, stock brokerage firms, and other financial companies. Our ability to attract and retain wealth management clients is dependent upon our ability to compete with competitors’ investment products, level of investment performance, client services, and marketing and distribution capabilities. If we are not successful, our results of operations and financial condition may be negatively affected.

The Company faces competition in pursuing acquisition opportunities, may not be able to identify attractive acquisition targets or may not be able to complete future acquisitions.

In pursuing acquisition opportunities, we may be in competition with other companies having similar growth strategies, including banks, bank holding companies, mutual banks and mutual holding companies. In addition, economic conditions may impede our ability to identify or acquire acquisition candidates. Furthermore, a number of banks in our markets or neighboring markets are organized as mutual banks and may not be interested in a transaction with a counterparty that is not organized in the same manner, such as the Company. These and other economic factors or competition for these acquisitions could result in increased acquisition prices and a lack of attractive acquisition opportunities. As a result, we may not be able to identify or acquire acquisition candidates.

In addition, we generally must receive federal regulatory approval before we can acquire a bank or bank holding company. Our ability to pursue or complete an attractive acquisition could be negatively affected by regulatory delay or other regulatory issues. We cannot be certain when or if, or on what terms and conditions, any required regulatory approvals will be granted. If we commit certain regulatory violations, including those that result in a downgrade in certain of our bank regulatory ratings, we may not be able to pursue future acquisitions for a period of time, or governmental authorities could preclude us from doing so even if we were otherwise able.

Completed acquisitions may not produce the expected results, may result in unforeseen integration difficulties and may dilute shareholders’ interests.

There can be no assurance that we will realize the anticipated positive results of any acquisition we complete, such as our recently completed acquisition of Northway, including results related to expected revenue increases, cost savings, increases in geographic or product presence or other projected benefits. We may incur substantial expenses related to acquisitions and integration of acquired companies. Successful integration of an acquired company may present challenges due to differences in systems, operations, policies and procedures, management teams and corporate cultures and may be more costly or difficult to complete than anticipated or have unanticipated adverse results. Integration efforts could divert management’s attention and resources, which could adversely affect our operations or results. Integration efforts could result in higher than expected customer loss, deposit attrition, loss of key employees, issues with systems and technology, disruption of our businesses or the businesses of the acquired company, or otherwise adversely affect our ability to maintain relationships with customers and employees or achieve anticipated benefits of the acquisition. We issued additional shares of our common stock as consideration for our acquisition of Northway, which diluted our shareholders’ ownership interests. Other future acquisitions may be material to us, and we may issue additional shares of our common stock to pay for those acquisitions, which would further dilute current shareholders’ ownership interests.

Liquidity Risk

Our cost of funds has increased and may in the future increase further as a result of loss of deposits, a change in deposit mix or changes in interest rates.

Deposits are a low-cost, stable source of funding. We compete with banks, other financial institutions and fintechs for deposits. Increases in short-term interest rates throughout 2022 and 2023 resulted in more intense competition in deposit pricing. Competition and increasing interest rates caused us to increase the interest rates we pay on deposits. Although the Federal Reserve began to lower short-term interest rates in 2024, competition for deposits remains elevated. In addition, a loss in the value of our investment or loan portfolio, perceived concerns regarding our or the Bank’s capital position or perceived concerns regarding the level of the Bank’s uninsured and uncollateralized deposits could cause rapid and significant deposit outflows. Funding costs may increase further if we lose deposits and are forced to replace them with more expensive sources of funding, if clients shift their deposits into higher cost products or if we need to continue to raise interest rates to avoid losing deposits. Higher funding costs reduce our net interest margin, net interest income and net income. If we were to experience a significant outflow of deposits, we may face significantly increased funding costs, suffer significant losses and have a significantly reduced ability to raise new capital.

As of December 31, 2025, brokered deposits made up 2% of our total deposits. We have utilized and will continue to utilize brokered deposits when it is a more cost effective source of funding compared to alternative funding sources. Should we become less than well-capitalized under the prompt corrective action framework, our use of brokered deposits may be limited, which could result in the use of more costly funding sources that would reduce our net interest margin, net interest income and net income. See “Supervision and Regulation—Capital Adequacy and Safety and Soundness—Prompt Corrective Action” and “Supervision and Regulations—Regulation of the Bank—Brokered Deposits” for additional information on the prompt corrective action framework and the regulation of brokered deposits.

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

The Company and the Bank 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 core deposit growth and repayments and maturities of loans and investments. These sources include brokered deposits, borrowings through the Federal Home Loan Bank of Boston (“FHLBB”) and correspondent banks, proceeds from the sale of investments and loans, and liquidity resources at the holding company. Our ability to manage liquidity will be severely constrained if we are unable to maintain access to funding or if adequate financing is not available to accommodate future growth at acceptable costs, or if there are unforeseen outflows of cash or collateral. In addition, if we are required to rely more heavily on more expensive funding sources to support future growth, our revenues may not increase proportionately to cover our costs. In this case, operating margins and profitability would be adversely affected. Turbulence in the capital and credit markets may adversely affect our liquidity and financial condition and the willingness of certain counterparties and customers to do business with us.

We could lose access to sources of liquidity if we were to experience financial or regulatory issues.

We rely on sources of liquidity provided by the Federal Reserve, such as the Federal Reserve discount window and other liquidity facilities that the Federal Reserve may establish from time to time, as well as liquidity provided by FHLBB. To access these sources of liquidity, the Federal Reserve or FHLBB may impose conditions that we and the Bank are in sound financial condition (as determined by the Federal Reserve or FHLBB) or that we and the Bank maintain minimum supervisory ratings. If we or the Bank were to experience financial or regulatory issues, it could affect our or the Bank’s ability to access liquidity facilities, including at times when we or the Bank needs additional liquidity for the operation of its business. If we or the Bank were to lose access to these liquidity sources, it could have a material adverse effect on our operations and financial condition.

We are a holding company and dependent upon our subsidiary for dividends, distributions and other payments to meet our liquidity needs.

We are a legal entity separate and distinct from our direct and indirect subsidiaries. Our revenue (on a parent-only basis) is derived primarily from interest and dividends paid to us by the Bank. Our right, and consequently the right of our shareholders, to participate in any distribution of the assets or earnings of the Bank through the payment of such dividends or otherwise is necessarily subject to the prior claims of creditors of the Bank (including depositors), except to the extent that certain claims of us in a creditor capacity may be recognized.

Holders of our common stock are entitled to receive dividends only when, and if declared by our Board of Directors. Although we have historically declared cash dividends on our common stock, we are not required to do so and our Board of Directors may reduce or eliminate our common stock dividend in the future. The FRB has authority to prohibit bank holding companies from paying dividends if such payment is deemed to be an unsafe or unsound practice. Additionally, the OCC has the authority to use its enforcement powers to prohibit a bank from paying dividends if, in its opinion, the payment of dividends would constitute an unsafe or unsound practice. Further, as a bank holding company, we are required to inform and consult with FRB supervisory staff prior to declaring and paying a dividend that exceeds earnings for the period for which the dividend is being paid. If we experience losses in a series of consecutive quarters, we may be required to inform and consult with the FRB supervisory staff prior to declaring or paying any dividends. In this event, there can be no assurance that the FRB will approve the payment of such dividends. Our ability to pay dividends would also be restricted under current regulatory capital rules if we do not maintain a capital conservation buffer. A reduction or elimination of dividends could adversely affect the market price of our common stock. See Item 1. “Business—Supervision and Regulation—Dividend Restrictions” and “Business—Supervision and Regulation—Regulatory Capital Requirements.”

Regulatory and Legal Risk

Our banking business is highly regulated, and we may be adversely affected by changes in law and regulation.

We are subject to regulation and supervision by the FRB, and the Bank is subject to regulation and supervision by the OCC and the FDIC, as well as regulations issued by the CFPB. Federal laws and regulations govern numerous matters affecting us, including changes in the ownership or control of banks and bank holding companies, maintenance of adequate capital and the financial condition of a financial institution, permissible types, amounts and terms of extensions of credit and investments, permissible non-banking activities, the level of reserves against deposits and restrictions on dividend payments. The OCC possesses the power to issue cease and desist orders to prevent or remedy unsafe or unsound practices or violations of law by banks subject to their regulation, and the FRB possesses similar powers with respect to bank holding companies. These and other restrictions limit the manner in which we may conduct business and obtain financing.

Our business is highly regulated and the laws, rules, regulations, and supervisory guidance and policies applicable to us are subject to regular modification and change, and there have been significant revisions to the laws and regulations applicable to banks and bank holding companies that have been enacted or proposed in recent years. We expect that we will remain subject to extensive regulation and supervision, and that the level of regulatory scrutiny may fluctuate over time, based on numerous factors, including changes in the U.S. presidential administration or one or both houses of Congress and public sentiment regarding financial institutions (which can be influenced by scandals and other incidents that involve participants in the industry). In particular, recent changes in national political leadership have introduced uncertainty into the direction and timing of any future regulation. Although an overall reduction in the regulation of the financial services sector could result in some operational and cost benefits, any potential new regulations or changes to existing regulations and supervisory expectations may necessitate changes to our existing regulatory compliance and risk management programs. New regulations and changes to existing regulations and supervisory expectations have increased, and may in the future increase, our costs over time.

In addition, changes to statutes, regulations or regulatory policies, or their interpretation or implementation, and/or regulatory practices, requirements or expectations, could affect us in substantial and unpredictable ways. In particular, the potential effects of a number of proposed regulations on us remain uncertain due to legal challenges and therecent changes in the U.S. presidential administration and control of the U.S. Senate, which could result in changing federal or state regulatory priorities.

We are unable to predict the form or nature of any future changes to statutes or regulation, including the interpretation or implementation thereof. Changes to statutes, regulations, or regulatory policies, including changes in interpretation or implementation of statutes, regulations, or policies, have and could in the future subject us to additional costs, limit the types of financial services and products we may offer, and/or increase the ability of non-banks to offer competing financial services and products, among other things. Failure to comply with laws, regulations, policies or supervisory guidance could result in enforcement and other legal actions by federal or state authorities, including criminal and civil penalties, the loss of FDIC insurance, revocation of a banking charter, other sanctions by regulatory agencies, civil money penalties, and/or damage to our brand, which could have a material adverse effect on our business, financial condition, and results of operations. See Item 1., “Business—Supervision and Regulation.”

We may become involved in lawsuits and legal proceedings that may lead to adverse consequences.

As a participant in the financial services industry, many aspects of the Company’s business involve substantial risk of legal liability. For example, banking organizations have been subject to claims regarding patent infringement or other violations of intellectual property rights in recent years which, in some cases, have resulted in large judgments against the banks. From time to time, we are named or threatened to be named as defendants in various lawsuits, including class actions, arising from our business activities. In addition, when other financial institutions receive adverse judgments in litigation or agree to settlements, that may encourage plaintiffs and their attorneys to bring and maintain claims, including class actions, against other financial institutions, including the Company. There is no assurance that litigation with private parties will not increase in the future. Future actions 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 harm to our brand. In addition, the scope of insurance coverage we maintain may not provide us with full, or even partial, coverage in any particular case. As a result, a judgment against us in any such litigation and/or legal costs incurred in defending us against such litigation could have a material adverse effect on our financial condition and results of operation.

We may incur fines, penalties and other negative consequences from regulatory violations, possibly even inadvertent or unintentional violations.

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 AML, 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. In addition, 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 were systems and procedures designed to ensure compliance in place at the time. There have been a number of significant enforcement actions in recent years by regulators, state attorneys general and the Department of Justice against banks and other non-bank financial institutions with respect to AML and sanctions laws, and some have resulted in substantial penalties including criminal pleas. Although the Company and the Bank have adopted policies and procedures designed to comply with these laws, any failure to comply with these laws and other regulations, or to maintain an adequate compliance program, could result in significant fines, penalties, lawsuits, regulatory sanctions, damage to our brand, or restrictions on our business.

We are subject to numerous laws designed to meet the credit needs of low- and moderate-income communities and 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 Community Reinvestment Act, 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 FRB, OCC, CFPB, the Department 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 Community Reinvestment Act, 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 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. 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-Supervision and Regulation-Regulatory Capital Requirements” for additional information on capital requirements applicable to us and the Bank.

Operational and Business Risk

Damage to our brand could significantly harm our business.

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 certain areas of Northern New England. Our actual or perceived failure 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, 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 result in damage to our brand 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 Maine and New Hampshire, any negative impact resulting from harm to our brand, 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. Moreover, the advent and expansion of social media creates the potential for rapid and widespread dissemination of information, including inaccurate, misleading, or false information, that could damage our brand and affect our ability to attract and retain customers and employees.

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. While we employ a broad and diversified set of risk monitoring and risk mitigation techniques, those techniques and the judgments that accompany their application may not be effective and may not anticipate every economic and financial outcome in all market environments or the specifics and timing of such outcomes. Market conditions over the last several years have involved unprecedented dislocations and highlight the limitations inherent in using historical data to manage risk. If our risk and control framework, or the assumptions underlying our framework, prove ineffective, we may not be able to mitigate our risk exposures effectively, and, as a result, we could incur litigation, negative regulatory consequences, damage to our brand or other adverse consequences, and we could suffer unexpected losses that may affect our business, financial condition or results of operations.

Our business may be adversely affected if we are unable to attract and retain qualified employees.

Competition for qualified personnel is intense in many areas of the financial services industry. If the Company provides inadequate succession planning, or is unable to continue to retain and attract qualified employees, this could result in a material adverse effect on the Company’s performance, including its competitive position.

We could be held responsible for environmental liabilities of properties we acquired through foreclosure.

In the course of business, we may acquire, through foreclosure, properties securing loans originated or purchased that are in default. Particularly in commercial real estate lending, there is a risk that material environmental violations could be discovered on these properties. In this event, we might be required to remedy these violations at the affected properties at our sole cost and expense. The cost of remedial action could substantially exceed the value of affected properties. 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.

Systems failures, interruptions or breaches of security concerning ourinformation base, including the information we maintain relating to our customers, could have an adverse effect on our financial condition and results of operations.

In the ordinary course of business, we rely on electronic communications and information systems to conduct our business and to store sensitive data, including financial information regarding customers. We are subject to certain operational risks, including, but not limited to, data processing system failures and errors, inadequate or failed internal processes, human error, customer or employee fraud, cyberattacks, hacking, identity theft and catastrophic failures resulting from terrorist acts or natural disasters. We depend upon data processing, software, communication, and information exchange on a variety of computing platforms and networks and over the internet, and we rely on the services of a variety of vendors to meet our data processing and communication needs. We cannot be certain that all of our systems are entirely free from vulnerability to attack or other technological difficulties or failures. If information security is breached or other technology difficulties or failures occur, information may be lost or misappropriated, services and operations may be interrupted and we could be exposed to claims from customers. A cybersecurity breach or cyberattack could persist for an extended period before being detected and could result in theft of sensitive data or disruption of our transaction processing systems. Any of these results could have a material adverse effect on our brand, business, financial condition, results of operations or liquidity.

We are subject to a variety of cybersecurity risks that, if realized, could adversely affect our business, financial condition and results of operations.

Information security risks for financial institutions such as the Company and the Bank are significant due to the use of online, telephone and mobile banking channels by customers and the increased sophistication and activities of organized crime, hackers, terrorists and other external parties. Third parties with whom we or our customers do business also present operational and information security risks to us. We see an increasing trend of cyberattacks targeting providers in the financial services industry, as well as increased security breaches or failures of their own systems. Our operations rely on the secure processing, transmission and storage of confidential information in our computer systems and networks. Our businesses rely on our digital technologies, computer and email systems, software, and networks to conduct their operations. As our reliance on technology systems increases, the potential risks of technology-related interruptions in our operations or the occurrence of cyber incidents also increases. Our technologies, systems, networks and our customers’ devices are periodically the target of cyberattacks, and may be the target of future cyberattacks, including through the introduction of computer viruses, and/or malicious code, or by means of phishing attacks, social engineering or other information security breaches. Malicious actors may also attempt to fraudulently induce employees, customers or other users of our systems to disclose sensitive information, including passwords and other identifying information, in order to gain access to data or our systems.

In recent years, there have been several well-publicized attacks on various companies, including in the financial services industry, and personal, proprietary, and public e-mail systems in which the perpetrators gained unauthorized access to confidential information and customer data, often through the introduction of computer viruses or malware, cyberattacks, phishing, social engineering or other means. Even if not directed at the Company or the Bank specifically, attacks on other entities with whom we do business or on whom we otherwise rely or attacks on financial or other institutions important to the overall functioning of the financial system could adversely affect, directly or indirectly, aspects of our business.

Information security risks continue to increase, in part because of the proliferation of new technologies, including artificial intelligence (“AI”), ongoing 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. We have expended substantial resources to protect our systems and, 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. Failure to properly utilize system enhancements that are implemented in the future could result in impairment charges and could result in significant costs to remediate or replace the defective components. In addition, we may incur significant training, licensing, maintenance, consulting and amortization expenses during and after systems implementations, and any such costs may continue for an extended period of time.

We may not be able to anticipate, detect, or implement effective preventative measures against all potential threats, particularly because the techniques used by cyber criminals change frequently, often are not recognized until launched and can be initiated from a variety of sources. In addition, a cybersecurity breach or cyberattack could persist for an extended period before being detected, which could exacerbate the harmful effects of a successful cyberattack. If one or more of the events described above occurs, this could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of our or our customers’ confidential, proprietary and other information, the theft of customer assets through fraudulent transactions or

disruption of our or our customers’ or other third parties’ business operations, which could result in legal or regulatory action, significant losses, increased compliance costs or damage to our brand, any of which could adversely affect our business, financial condition or results of operations. Because the investigation of any information security breach is inherently unpredictable and would require substantial time to complete, the Company may not be able to quickly remediate the consequences of any breach, which may increase the costs, and enhance the negative consequences associated with a breach. In addition, to the extent the Company’s insurance covers aspects of any breach, such insurance may not be sufficient to cover all of the Company’s losses.

As cybersecurity and data privacy risks for banking organizations and other financial institutions have significantly increased in recent years, cybersecurity and data privacy issues have become the subject of increasing legislative and regulatory focus. We could be adversely affected if new legislation or regulations are adopted or if existing legislation or regulations are modified such that we are required to alter our systems or are required to change our business practices or privacy policies. If cybersecurity, data privacy, data protection, data transfer or data retention laws are implemented, interpreted or applied in a manner inconsistent with our current practices, we may be subject to fines, litigation or regulatory enforcement actions or ordered to change our business practices, policies or systems in a manner that adversely affects our results of operations.

We must adapt to information technology changes in the financial services industry, which could present operational issues, require significant capital spending, or affect our brand.

The financial services industry is constantly undergoing technological changes, with frequent introductions of new technology-driven products and services. Our future success will depend, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy customer demands for convenience, as well as to create additional efficiencies in our operations. To compete effectively, the Company may use new and evolving technologies, including AI and machine learning, to help improve its customer service, marketing, and products or to automate certain business decisions or risk management practices, such as fraud identification. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. Failure to successfully implement and integrate future system enhancements could adversely impact the ability to provide timely and accurate financial information in compliance with legal and regulatory requirements, which could result in sanctions from regulatory authorities. Such sanctions could include fines and suspension of trading in our stock, among others. In addition, future system enhancements could have higher than expected costs and/or result in operating inefficiencies, which could increase the costs associated with the implementation as well as ongoing operations. Furthermore, legal and regulatory requirements relating to new technologies such as AI are evolving rapidly, and the inability to predict how this regulation will take shape and the absence of a uniform regulatory framework for AI may present unforeseen challenges in applying and relying on existing compliance systems. Complying with such requirements could increase expenses and exposure to legal or regulatory proceedings.

We rely on other companies to provide key components of our business infrastructure.

Third-party vendors provide key components of our business infrastructure. Any problems caused by these third parties, including as a result of their not providing us their services for any reason or their performing their services poorly, could adversely affect our ability to deliver products and services to our customers or otherwise conduct our business efficiently and effectively. Replacing these third party vendors could also entail significant delay and expense.

Third parties with which we do business could also be sources of information security risk to us, including from breakdowns, systems failures or cyber threats through their systems to our systems. Any of these occurrences could impact our ability to operate our business, or cause financial loss, potential liability to clients, damage to our brand or regulatory consequences, any of which could have a material adverse effect on our financial condition or results of operations.

Our operations and financial performance could be adversely affected by natural disasters, and climate change may exacerbate those risks and create compliance, strategic and other risks.

Our business, as well as the operations and activities of our customers, could be negatively affected by climate change. Climate change presents both immediate and long-term risks to us and our customers and these risks are expected to increase over time. Climate change presents several risks, including (i) operational risk from the physical effects of climate events on our facilities and other assets, on our vendors’ facilities and on our customers’ assets, including real estate pledged as collateral for our loans; and (ii) transitional risks, including new or more stringent regulatory requirements and potential effects on our brand and/or changes in our business as a result of our climate change practices, our carbon footprint and our business relationships with customers who operate in carbon-intensive industries.

Natural disasters can disrupt our operations, result in damage to our properties, reduce or destroy the value of the collateral for our loans and negatively affect the economies in which we operate, which could have a material adverse effect on our results of operations and financial condition. A significant natural disaster, such as a tornado, hurricane, earthquake, fire or flood, could have a material adverse impact on our ability to conduct business (including as a result of damage to our own facilities or systems or to the facilities or systems of third-party vendors on which we rely), and our insurance coverage may be insufficient to compensate for losses that may occur. Because we primarily serve individuals and businesses located in Northern New England, a natural disaster likely would have a greater impact on our business, operations and financial condition than if our business were more geographically diverse.

Both the frequency and severity of some kinds of natural disasters, including wildfires, flooding, tornadoes and hurricanes, have increased, and we expect will continue to increase, as a result of climate change. In addition, long-term shifts in the climate, including altered distribution and intensity of rainfall, rising sea levels and a rising heat index, negatively affect our ability to predict the effects of natural disasters accurately. Climate change may result in reduced availability of insurance for our borrowers, including insurance that protects property pledged as collateral, or disrupt their operations, which could increase our credit risk by diminishing borrowers’ repayment capacity or collateral values.

To the extent the U.S. continues to transition to a low-carbon economy, related risks may arise from changes in consumer preferences, technologies, public policies and legal and regulatory requirements. New laws and regulations could result in significant costs as we implement compliance, disclosure and other programs. Failure to comply with any applicable laws or regulations could result in legal or regulatory sanctions and harm to our brand. Failure to adequately consider transition risks in our operations could lead to a loss of market share, lower revenues, decreased asset values and higher credit costs. In addition, we may not be able to meet the diverging expectations and priorities of different groups, including our employees, shareholders and regulators. We could also experience increased expenses resulting from strategic planning, litigation and technology and market changes, and harm to our brand as a result of negative public sentiment, regulatory scrutiny and reduced investor and employee confidence due to our response to climate change and our climate change strategy.

Risks associated with climate change are continuing to evolve rapidly, making it difficult to assess the effects of climate change on our business, and we expect that climate change-related risks will continue to evolve and increase over time.

Acts of terrorism, pandemics and other external events could harm our business.

Acts of terrorism, war or other international hostilities, civil unrest, violence or pandemics could cause disruptions to our business or the economy as a whole. Any of these events could affect us directly (for example, by interrupting our systems, causing significant damage to our facilities or otherwise preventing us from conducting our ordinary business) or indirectly as a result of effects on our borrowers and other customers or third-party vendors (for example, by damaging property pledged as collateral for our loans). The Company has suffered, and could in the future suffer, adverse consequences to the extent that pandemics, terrorist activities, civil unrest, international hostilities, or other external events affect the financial markets or the economy in general or in any region in which the Company, or third parties on which the Company relies, operate.

Depending on the impact of external events on general economic and market conditions, there is a risk that adverse conditions could occur or worsen, including supply chain disruptions; higher inflation; decreased demand for our products and services or those of our borrowers, which could increase credit risk; challenges related to maintaining sufficient qualified personnel due to labor shortages, talent attrition, employee illness, or willingness to return to work; and disruptions to our business operations or those of our counterparties, vendors and other service providers.

Our ability to mitigate the adverse consequences of these occurrences is in part dependent on the quality of our resiliency planning, and our ability, if any, to anticipate the nature of any such event that occurs. The adverse effects of pandemics, terrorist activities, civil unrest, international hostilities or other external events also could be increased to the extent that there is a lack of preparedness on the part of national or regional emergency responders or on the part of other organizations and businesses that we transact with, particularly those that we depend upon, but have no control over.

Accounting and Tax Risk

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. generally accepted accounting principles, we are required to use certain assumptions and estimates in preparing our financial statements, including in determining credit loss reserves, reserves related to litigation 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. For additional information, see Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates.”

We may be required to write down goodwill and other identifiable intangible assets.

When we acquire a business, a portion of the purchase price of the acquisition may be allocated to goodwill and other identifiable intangible assets. The excess of the purchase price over the fair value of the net identifiable tangible and intangible assets acquired determines the amount of the purchase price that is allocated to goodwill. At December 31, 2025, our goodwill and other identifiable intangible assets totaled $194.1 million. Under current accounting standards, if we determine goodwill or intangible assets are impaired, we would be required to write down the value of these assets to fair value. We conduct an annual review, or more frequently if events or circumstances warrant such additional review, to determine whether goodwill is impaired. We recently completed our goodwill impairment analysis as of November 30, 2025 and concluded goodwill was not impaired. We conduct a review of our other intangible assets for impairment should events or circumstances warrant such review. There were no triggers for such review for impairment for other intangible assets for the year ended December 31, 2025. We may be required to take an impairment charge in the future. Any impairment charge would have a negative effect on our shareholders’ equity and financial results and may cause a decline in our stock price.

On January 2, 2025, we completed the acquisition of Northway. As part of this acquisition, additional goodwill and other intangible assets were recognized upon completion of our purchase accounting, as further described within Note 2 of the consolidated financial statements. The goodwill and intangible assets created from the acquisition of Northway were subject to assessment for impairment as described above.

Changes in accounting standards can be difficult to predict and can materially impact how we record and report our financial condition and results of operations.

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 that govern the preparation of our financial statements. These changes can be hard to anticipate and implement and can materially impact how we record and report our financial condition and results of operations. For example, the introduction of Accounting Standard Update No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), as updated, commonly referred to as “CECL,” substantially changed how we calculate our allowance for credit losses. Other future changes in accounting standards could materially impact how we report our financial condition, and we cannot predict whether such standards will be adopted or their resultant impact.

Changes in tax laws and regulations and differences in interpretation of tax laws and regulations may adversely impact our financial statements.

Local, state or federal tax authorities may interpret tax laws and regulations differently than we do and challenge tax positions that we have taken on tax returns. This may result in differences in the treatment of revenues, deductions, credits and/or differences in the timing of these items. The differences in treatment may result in payment of additional taxes, interest or penalties that could have a material adverse effect on our results. In addition, there may be future changes to tax laws, administrative rulings or court decisions that could adversely affect our financial condition, including an increased provision for income taxes and/or reduced net income. We are not able to predict the timing or impact of any changes in local, state or federal tax laws.

Item 1C. Cybersecurity

Cybersecurity Risk Management and Strategy

The Company has developed and implemented a comprehensive cybersecurity risk management program that is intended to protect the secure processing, transmission and storage of confidential information in its computer systems and networks. The Company’s cybersecurity risk management program, a component of the Company’s Enterprise Risk Management (“ERM”) Program, is based on the National Institute of Standards and Technology (“NIST”) Cybersecurity Framework, regulatory guidance and other industry standards. The Company’s process for identifying, assessing, managing and prioritizing cybersecurity risks throughout the Company includes:

•A third party risk assessment program for the Company’s third party vendors that access the Company’s data (each, a “Vendor”) to ensure that all Vendors meet the Company’s cybersecurity requirements, including, periodic risk assessments of Vendors, monitoring Vendor compliance with the Company’s cybersecurity requirements, and a requirement that all contracts with Vendors include provisions requiring the Vendor to notify the Company of any cyber incident, and/or to maintain minimum levels of cybersecurity insurance;

•A security awareness program that includes training employees on best practices for securing the Company’s data, as well as regular social engineering testing to keep employees informed of cybersecurity threats and to train them to look for malicious emails and other potential cybersecurity threats;

•A dedicated information security team that monitors threats and vulnerabilities that arise, and regularly performs threat intelligence and vulnerability management;

•The Company’s engagement of a third party to conduct periodic independent testing of the Company’s cybersecurity defenses to confirm that the defenses are effective;

•A Managed Detection and Response (“MDR”) service that continuously monitors the Company’s systems and alerts the Company’s information security team of any detected anomalies or suspicious activity and stops any event that is deemed dangerous to the Company’s systems or networks;

•An Incident Response Plan (“IRP”) and Business Continuity Plan (“BCP”) which outline steps to be taken during a cyber incident and to recover systems and continue business operations following a cyber incident; and

•A Cybersecurity Incident Response Team (“CSIRT”) that tracks cyber incidents, including those that affect third parties that are handling the Company’s data.

Cybersecurity Threats

During the fiscal year ended December 31, 2025, the Company did not identify any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected, or that are reasonably likely to materially affect the Company, including its business strategy, results of operations, or financial condition other than the risks described in Item 1A. “Risk Factors”.

Cybersecurity Governance

Board of Directors’ Oversight. The Company’s Board of Directors oversees the Company’s cybersecurity program, including the oversight of risks related to cybersecurity through various committees that are responsible for monitoring and testing the Company's information security. The Board of Directors conducts an annual review of the Company’s cybersecurity- related policies. Quarterly, the Company’s SVP, Director of Information Security (“DIS”) presents reports to the Audit Committee on vulnerability management and cybersecurity testing effectiveness, emerging threats and industry and regulatory changes that affect cybersecurity, and responds to inquiries from the Audit Committee. In addition, the Technology Committee receives and evaluates quarterly updates from the DIS on cybersecurity performance and on cybersecurity trends and strategies. The Board of Directors receives quarterly updates from the EVP, CRO on cybersecurity metrics and the cybersecurity risk management program’s performance.

Management Oversight. While the Board of Directors and its Audit and Technology Committees oversee management’s processes related to cybersecurity risks, management is responsible for identifying, monitoring and mitigating the material cybersecurity risks that face the Company. The Company’s CRO is directly responsible for the overall cybersecurity risk management program which is a part of the Company's ERM Program. The CRO and the DIS oversee the information security department’s implementation and maintenance of the cybersecurity risk management program, including oversight of Vendors and regular reporting to the Board of Directors and its Audit and Technology Committees on the effectiveness of the

cybersecurity risk management program. The DIS updates the CRO as appropriate, including as new developments or information related to cyber incidents arise.

The Company’s CRO has over 30 years of experience in cybersecurity and information technology. The CRO joined the Company in 2011 and became CRO in July 2023. Prior to becoming CRO, he served as SVP and Director of Information Security & ERM for six years and prior to that served five years as VP and Senior Information Security Officer of the Company. Prior to joining the Company, the CRO had a ten year career in information technology and began his career serving with the U.S. Air Force, specializing in information technology, cybersecurity, risk mitigation, and encrypted communications.

The Company’s DIS joined the Company in 2023 and has over 23 years of experience in information technology and cybersecurity. The DIS has held senior management positions in information security for the past ten years. The DIS holds several industry certifications including Certified Information Systems Security Professional (“CISSP”), Certified Information Systems Auditor (“CISA”), Certified in Risk and Management Systems Controls (“CRISC”) and Certified Data Privacy Solutions Engineer (“CDPSE”).

Item 2. Properties

As of December 31, 2025, the Company owns its principal executive office in Camden, Maine, and leases additional executive offices in Portland, Maine. The Company also leases a service center in Camden, Maine, and owns or leases, and operates, 72 branches located throughout Maine and New Hampshire. None of the properties owned by the Company are subject to a mortgage or other encumbrance. All facilities are fully utilized and considered suitable and adequate for the purposes intended.

For additional information regarding the Company's premises and equipment and lease obligations see Notes 6 and 7 of the consolidated financial statementswithin Item 8. Financial Statements and Supplementary Data.

Item 3. Legal Proceedings

The Company is currently involved, and from time to time in the future may become involved, in various legal claims that arise in the normal course of the Company’s business. The Company may also in the future become involved in other regulatory, judicial and/or arbitration proceedings relating to matters that arise in connection with the conduct of the Company’s business. Because of the difficulty in predicting the outcome of these matters, particularly when they are in their early stages, the Company cannot predict what the final outcome of each legal proceeding may be, or what the eventual loss, fine or penalty related to each proceeding may be, if any. Based on currently available information, in our opinion the results of legal proceedings that are currently pending are not expected to have a material effect on our consolidated financial statements.

Reserves are established for legal claims only when losses associated with the claims are judged to be probable, and the loss can be reasonably estimated. In many lawsuits and arbitrations, it is not possible to determine whether a liability has been incurred or to estimate the ultimate or minimum amount of that liability until the case is close to resolution, in which case a reserve will not be recognized until that time. As of December 31, 2025 and 2024, the Company did not maintain material reserves against legal claims.

Item 4. Mine Safety Disclosures

PART II

Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

The Company’s common stock is traded on the NASDAQ Global Market (“NASDAQ”) under the ticker symbol “CAC.” The Company has paid quarterly dividends since its foundation in 1984. The high and low closing sales prices (as quoted by NASDAQ for 2025 and 2024) and cash dividends declared per share of the Company’s common stock, by calendar quarter for the past two years, were as follows:

High Low High Low

As of February 24, 2026, there were 16,925,329 shares of the Company’s common stock outstanding, and there were approximately 1,000 holders of record of the Company’s common stock. Such number of shareholders does not reflect the number of persons or entities holding stock in nominee name through banks, brokerage firms and other nominees.

Although the Company has historically paid quarterly dividends on its common stock, the Company’s ability to pay such dividends depends on a number of factors, including restrictions under federal laws and regulations on the Company’s ability to pay dividends, and as a result, there can be no assurance that dividends will be paid in the future. For further information on dividend restrictions, refer to Item 1.“Business—Supervision and Regulation” and Item 7.“Management’s Discussion and Analysis of Financial Condition and Results of Operations—Capital Resources.”

The following graph illustrates the annual percentage change in the cumulative total shareholder return of the Company’s common stock for the period December 31, 2020 through December 31, 2025. For purposes of comparison, the graph illustrates comparable shareholder returns of the S&P U.S. SmallCap Banks Index and the Russell 2000 Index. The graph assumes a $100 investment on December 31, 2020 in the Company’s common stock and each of the foregoing indices and assumes the

reinvestment of all dividends. The comparisons in the graph are based on historical data and are not indicative of, nor intended to forecast, future performance of the Company’s common stock.

Stock Performance Graph

In January 2024, the Board of Directors approved a common stock repurchase program, authorizing management to repurchase up to 750,000 shares, or approximately 5%, of the Company's outstanding common stock, that had an expiration date of the earlier of (i) reaching the authorized share repurchase amount, (ii) vote by the Board of Directors to terminate the plan, or (iii) one year. As of December 31, 2024, the Company repurchased 50,000 shares at an average price of $32.19, none of which were repurchased during the fourth quarter of 2024. This repurchase program expired in January 2025 and there were no shares repurchased during 2025.

Issuer's Purchases of Equity Securities

NON-GAAP FINANCIAL MEASURES AND RECONCILIATION TO GAAP

In addition to evaluating the Company’s results of operations in accordance with GAAP, management supplements this evaluation with an analysis of certain non-GAAP financial measures, such as adjusted net income; adjusted diluted earnings per share; adjusted return on average assets; adjusted return on average equity; pre-tax, pre-provision income and adjusted pre-tax, pre-provision income; the efficiency ratio; return on average tangible equity and adjusted return on average tangible equity; tangible book value per share and tangible common equity ratio; net interest income (fully-taxable equivalent); core net interest margin (fully taxable equivalent); and core deposits and average core deposits. We utilize 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. These disclosures should not be viewed as a substitute for GAAP operating results, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other financial institutions.

Adjusted Net Income; Adjusted Diluted Earnings per Share; Adjusted Return on Average Assets; and Adjusted Return on Average Equity. Adjusted net income, adjusted diluted earnings per share, adjusted return on average assets and adjusted return on average equity are each supplemental measures that exclude certain transactions as outlined and calculated in the table below. Each item reconciles to reported net income, diluted earnings per share, return on average assets and return on average equity. The Company believes these adjusted financial metrics assist users of its financial statements with their financial analysis period-over-period as they are adjusted for certain non-recurring items.

Pre-Tax, Pre-Provision Income and Adjusted Pre-Tax, Pre-Provision Income. Pre-tax, pre-provision income is a supplemental measure of operating earnings and performance. Pre-tax, pre-provision income is calculated as net income before adjustment for provision (credit) for credit losses and adjustment for income tax expense. This supplemental measure became widely used by financial institutions as a measure of financial performance for comparability across financial institutions.

Adjusted pre-tax, pre-provision income is a supplemental measure with certain non-recurring expenses excluded. We believe the following adjusted financial information and metrics assist users of our financial statements with their financial analysis period-over-period as it adjusts for certain non-recurring items.

For the Year EndedDecember 31,

Adjustment for provision (credit) for credit losses 22,290 (404) 2,100

Adjustment for gain on sale of premises and equipment, net (675) — —

Adjustment for net loss on sale of securities — — 10,310

Efficiency Ratio. The efficiency ratio represents an approximate measure of the cost required for the Company to generate a dollar of revenue. This is a common measure used by financial institutions and is a key ratio for evaluating Company performance. The efficiency ratio is calculated as the ratio of (i) total non-interest expense, adjusted for certain operating expenses, as necessary, to (ii) net interest income on a tax equivalent basis plus total non-interest income, adjusted for certain other income items, as necessary.

For the Year EndedDecember 31,

(1) Reported on a tax-equivalent basis using a 21% income tax rate.

(2) Revenue is the sum of net interest income and non-interest income.

Return on Average Tangible Equity and Adjusted Return on Average Tangible Equity. Return on average tangible equity is the ratio of (i) net income, adjusted for tax effected amortization of CDI assets and other adjustments, as necessary, to (ii) average shareholders' equity, adjusted for average goodwill and CDI assets. This adjusted financial ratio reflects a shareholders' return on tangible capital deployed in our business and is a common performance measure within the financial services industry.

Adjusted return on average tangible equity is calculated the same as return on average tangible equity but uses adjusted net income which excludes certain transactions as shown in the table above. The Company believes this adjusted metric assists users of its financial statements with their period-over-period financial analysis as it is adjusted for certain non-recurring items.

For the Year EndedDecember 31,

Return on Average Tangible Equity:

Adjustment for amortization of CDI assets 5,893 556 592

Net income, adjusted for amortization of CDI assets $ 69,698 $ 53,443 $ 43,851

Adjusted Return on Average Tangible Equity:

Tangible Book Value per Share and Tangible Common Equity Ratio. Tangible book value per share is the ratio of (i) shareholders’ equity less goodwill, and CDI assets to (ii) total common shares outstanding at period end. Tangible book value per share is a common measure within our industry when assessing the value of a company as it removes goodwill and other intangible assets generated within purchase accounting upon a business combination.

Tangible common equity is the ratio of (i) shareholders’ equity less goodwill and CDI assets to (ii) total assets less goodwill and CDI assets. This ratio is a measure used within our industry to assess whether or not a company is highly leveraged.

(In thousands, except number of shares and per share data) December 31,

Net Interest Income (Fully-Taxable Equivalent). Net interest income on a fully-taxable equivalent basis is net interest income plus the taxes that would have been paid had tax-exempt securities been taxable. This number attempts to enhance the comparability of the performance of assets that have different tax liabilities. This is a common measure with the financial services industry and is used within the calculation of net interest margin on a fully-taxable equivalent basis.

(1) Brokered deposits are excluded from total average deposits, as presented on the Average Balance, Interest and Yield/Rate analysis table.

CRITICAL ACCOUNTING ESTIMATES

Critical accounting estimates are defined as those that are reflective of significant judgments and uncertainties, and could potentially result in materially different results under different assumptions and conditions. In preparing the Company’s consolidated financial statements, management is required to make significant estimates and assumptions that affect assets, liabilities, revenues, and expenses reported. Actual results could materially differ from our current estimates, as a result of changing conditions and future events. Estimates particularly critical and susceptible to significant near-term change, include (i) the ACL on loans, (ii) fair value of loans acquired in business combinations and (iii) goodwill.

Refer to Note 1 of the consolidated financial statements for additional details of the Company's accounting policies, including new accounting standards recently adopted.

Allowance for Credit Losses (“ACL”). The ACL is calculated using the current expected credit loss accounting model, often referred to as “CECL.” Under CECL, the ACL at each reporting period serves as our best estimate of projected credit losses over the contractual life of certain assets, adjusted for expected prepayments, given an expectation of economic conditions and forecasts as of the valuation date.

The recorded ACL on loans is determined based on the amortized cost basis of the assets and may be determined at various levels, including homogeneous loan pools and individual credits with unique risk factors. We use a discounted cash flow approach to calculate the ACL for each loan segment. Within the discounted cash flow model, a probability of default (“PD”) and loss given default (“LGD”) assumption is applied to calculate the expected loss for each loan segment. PD is the probability the asset will default within a given timeframe and LGD is the percentage of the assets not expected to be collected due to default. PD and LGD data may be derived using (1) internal historical default and loss experience, as well as from (2) external data if there are not statistically meaningful loss events or our own internal loss data does not span a full economic cycle for a given loan segment.

CECL may create more volatility in our ACL and particularly in our ACL on loans. Under CECL, our ACL may increase or decrease period-to-period based on many assumptions, including, but not limited to: (i) macroeconomic forecasts and conditions; (ii) a change in the forecast period; (iii) a change in the reversion speed; (iv) a change in the prepayment speed assumption; (v) various qualitative factors outlined in ASU 2016-13.

ACL on Loans. We consider the ACL on loans to be a critical accounting estimate given the uncertainty in evaluating the allowance required to cover management’s estimate of all expected credit losses over the expected contractual life of the loans in its portfolio. Determining the appropriateness of the allowance is a key management function that requires significant judgment and estimate by management about the effect of matters that are inherently uncertain. Subsequent evaluations of the current loan portfolio, in light of the factors then prevailing, may result in significant changes in the allowance in future periods. While our current evaluation indicates that the ACL on loans at December 31, 2025 and 2024 was appropriate, the allowance may need to be increased under adversely different conditions or assumptions.

The significant key assumptions used with the ACL on loans calculation at December 31, 2025 and 2024 using the CECL methodology, included:

•Macroeconomic factors (loss drivers): Macroeconomic factors are used within our discounted cash flow model to forecast the PD over the forecast period. As macroeconomic factor conditions worsen, the PD increases, and the corresponding LGD increases, resulting in an increase in the ACL on loans. To identify the most appropriate loss drivers for each portfolio segment, we evaluate a broad set of economic indicators and perform correlation and back‐testing analyses to determine which variables demonstrate the strongest and most stable relationship to historical loss experience. We monitor and assess Maine unemployment, changes in National GDP, changes in National Retail Sales, and changes in Maine's Housing Price Index at least annually to determine if these macroeconomic factors

continue to be the most predictive indicator of losses within our loan portfolio. Macroeconomic factors used in the calculation of the ACL on loans may change from time to time and in times of greater uncertainty, we may consider a range of possible forecasts and evaluate the probability of each scenario. We reassessed our loss factors in the first quarter of 2025 and removed change in Maine GDP and added change in National Retail Sales to be used within the discounted cash flow model.

•Forecast period and reversion speed: The company uses a reasonable and supportable forecast period in developing the ACL, which represents the time period that management believes it can reasonably forecast the identified loss drivers. Generally, the forecast period management believes to be reasonable and supportable is set annually and validated through an assessment of economic leading indicators. In periods of greater volatility and uncertainty, such as that seen across the global markets and economies, including the U.S., we are likely to use a shorter forecast period, whereas when markets, economies and various other factors are considered more stable and certain, we are likely to use a longer forecast period. Generally, we expect our forecast period to range from one to three years. Once the reasonable and supportable forecast period is determined, the company reverts its loss expectations to the long-run historical mean for the remainder of the contract life of the asset, adjusted for prepayments. In determining the length of time over which the reversion will take place (i.e. “reversion speed”), we consider such factors such as, but not limited to, historical loan loss experience over previous economic cycles, as well as where we believe we are within the current economic cycle. At December 31, 2025 and 2024, we used a two-year forecast period and a two-year reversion period for each loan segment to measure the ACL on loans as we believe this methodology aligns the economic forecasted data used to calculate the ACL with the Company’s internal views of the future economic state.

•Prepayment speeds: Prepayment speeds are determined for each loan segment utilizing our own historical loan data, as well as consideration of current environmental factors. The prepayment speed assumption is utilized with the discounted cash flow model (i.e. the CECL model) to forecast expected cash flows over the contractual life of the loan, adjusted for expected prepayments. A higher prepayment speed assumption will drive a lower ACL, and vice versa.

•Qualitative factors: Companies are required to consider various qualitative factors that may impact expected credit losses. We continue to consider qualitative factors in determining and arriving at our ACL on loans each reporting period. In 2025, we provided for an additional qualitative factor for the loans acquired in the Northway acquisition.

As of December 31, 2025 and 2024, the recorded ACL on loans was $45.3 and $35.7 million, respectively, and represented our best estimate of expected credit losses within our loan portfolio as of each date. However, we may adjust our assumptions to account for differences between expected and actual losses each period. A future change of our assumptions will likely alter the level of allowance required and may have a material impact on future results of operations and financial condition. The ACL is reviewed periodically within a calendar quarter to assess trends in the aforementioned key assumptions, as well as asset quality within our loan portfolio, and we consider the impact of these trends on the ACL and the Company's financial condition, if any. The ACL on loans is reviewed and approved on a quarterly basis by the Company's Audit Committee, and later reviewed and ratified by the Bank's Board of Directors.

Refer to “—Results of Operations—Provision for Credit Losses,” “—Financial Condition—Asset Quality,” and Note 4 of the consolidated financial statements for further discussion.

Fair Value of Loans Acquired in Business Combinations. The loans acquired as part of the Northway acquisition were accounted for at fair value on January 2, 2025 (“Acquisition Date”). The fair value for these acquired loans was determined using a discounted cash flow approach that incorporated expected credit and prepayment-adjusted cash flows, discounted at market-based rates. This analysis considered factors such as loan type and collateral, interest rate structure, remaining term, credit quality indicators, and amortization status. Loans with similar risk characteristics were pooled for valuation purposes. Discount rates for loans were developed using a “build-up” approach, which considered the cost of funds, capital charges, servicing costs, liquidity premiums, and risk premiums.

The discount rate and prepayment speeds were the most significant assumptions within in the acquired loan portfolio valuation. Changes in these inputs would have a material effect on the fair value measurement, in particular:

•Discount rate: Increases or decreases in the discount rate would result in a significant change in the estimated fair value of the acquired loan portfolio due to the sensitivity of discounted cash flows to market‐based yield assumptions.

•Prepayment speed: Variations in expected prepayment speeds, whether higher or lower, would result in a meaningful change in the fair value estimate because prepayment behavior directly affects projected cash flows and expected loan duration.

Additional information regarding these accounting policies is included in Note 1, Significant Accounting Policies, and Note 2, Business Combinations, to the Company’s audited consolidated financial statements in Item 8 of this Form 10-K.

Goodwill. We record all acquired assets and liabilities at fair value, which is an estimate determined by the use of internal and external valuation techniques. As part of purchase accounting, we typically acquire goodwill as part of the purchase price, which is subject to ongoing periodic impairment tests.

Goodwill impairment evaluations are required to be performed at least annually, but may be required more frequently if certain conditions indicate a potential impairment may exist. Our policy is to perform the goodwill impairment analysis annually as of November 30th, or more frequently as warranted. The goodwill impairment evaluation is required to be performed at the reporting unit level. Goodwill impairment is measured by the amount the book value of the reporting unit exceeds its fair value, and an impairment charge is recorded for the lesser of this amount or the amount to write-down goodwill to zero.

We elected to use the quantitative analysis to perform the annual goodwill impairment assessment as of November 30, 2025 and 2024 and concluded that goodwill was not impaired. We may use a qualitative analysis to evaluate goodwill for impairment when it is believed that it is not more-likely-than-not that the fair value of the reporting unit is below its book value, or if a quantitative analysis was recently used to estimate the fair value of the reporting unit, and there are not any indications of events that would suggest such conclusions for impairment have changed. The Company did not recognize any impairment of goodwill in 2025, 2024 or 2023.

Refer to “—Financial Condition—Goodwill and Core Deposit Intangible Assets” and Note 5 of the consolidated financial statements for further discussion.

EXECUTIVE OVERVIEW

Strategic Overview. Our long-term strategy is anchored in three clear priorities: Running the Bank, Evolving the Bank, and Growing the Bank. Together, these priorities guide our actions, align our investments, and position the Company to deliver sustainable performance and long-term shareholder value.

•Running the Bank is about delivering consistent, reliable results by building on our core strengths and disciplined foundation. As we pursue change and growth, maintaining a strong operating framework remains paramount. This includes investing in and strengthening our corporate culture; driving toward top-quartile employee engagement and exceptional customer experiences through our “One Bank” approach; honoring our commitment to the communities we serve; and maintaining balance-sheet strength across interest rate risk, liquidity, asset quality, and capital. This focus provides the stability and resilience necessary to support our strategic ambitions.

•Evolving the Bank enables us to respond to a dynamic marketplace with agility and innovation. We are advancing our digital agenda across both customer and employee experiences to increase adoption, productivity, and efficiency. At the same time, we are repositioning our retail franchise to meet changing customer needs and expectations. Central to this evolution is the development of a high-touch, team-based operating model that leverages specialized expertise and places the customer at the center of every interaction.

•Grow the Bank focuses on expanding our customer base and deepening relationships by leveraging technology, scalable capabilities, and local market expertise. We pursue both organic and inorganic growth opportunities across our footprint. Organically, we see significant opportunity to scale our commercial franchise in our Southern Maine and New Hampshire growth markets through targeted hiring and the development of internal talent. Inorganically, we continue to evaluate merger and acquisition opportunities that offer compelling strategic and financial benefits, as demonstrated by our acquisition of Northway Financial, Inc., the holding company of Northway Bank, completed on January 2, 2025.

2025 Overview. On January 2, 2025, we completed ouracquisition of Northway, which significantly increased our presence in New Hampshire by adding 17 branches and over 100 new employees. In mid-March 2025, we completed the full integration of the two banks and began realizing the combined organization’s full financial potential through the execution of synergies across employees, technology, software and vendor contracts. The integration of operations, systems, and teams enabled us to leverage the strengths of both institutions more effectively, resulting in meaningful improvements in scale, operating efficiency, and revenue‐generating capacity. As our post‐merger performance began to reflect the benefits of a larger balance sheet, a broader customer base, and an expanded geographic footprint, we delivered annual net income of $65.2 million and diluted EPS of $3.84 for 2025, compared to $53.0 million and $3.62, respectively, in 2024. On a non-GAAP basis, we

reported annual adjusted net income of $74.4 million and diluted EPS of $4.39 for December 31, 2025, an increase of 39% and 20%, respectively, over 2024.

Throughout 2025, we executed several initiatives to improve our net interest margin. These actions, together with the Federal Reserve’s 75‐basis‐point reduction in the federal funds rate during the second half of the year, contributed to a meaningful increase in our net interest margin, from 3.04% for the first quarter of 2025 to 3.29% for the fourth quarter of 2025. Excluding the impact of purchase accounting accretion income, our non-GAAP, core net interest margin also increased significantly from 2.68% for the first quarter of 2025 to 2.92% for the fourth quarter of 2025. The steady improvement in our net interest margin throughout 2025, resulted in a net interest margin of 3.17% for the year ended December 31, 2025, compared to 2.46% for the year ended December 31, 2024.

The completion of the Northway acquisition and successful execution of our cost take-out strategies, as well as an improving net interest margin throughout 2025, drove significant improvement in the Company’s profitability metrics compared to 2024. We believe the Company is well-positioned for 2026, highlighted by the strength of its reported fourth quarter financial metrics, which included a return on average assets of 1.28%, a return on average equity of 13.01%, and a non-GAAP return on average tangible equity of 19.06%.

2025 Highlights. Our highlights for 2025 include:

Completed Northway Acquisition and Integration - Successfully completed the acquisition of Northway on January 2, 2025. Following the integration in mid-March 2025 and the realization of cost synergies across the combined organization, the Company delivered record quarterly net income in both the third and fourth quarters of 2025.

Improving Profitability – In 2025, total revenues (sum of net interest income and non-interest income) reached $255.8 million, an increase of 45% over 2024, while non-interest expense for 2025 was $154.8 million, an increase of 38% over 2024. The Company’s 2025 performance resulted in strong operating leverage generation and improvement in each of our profitability metrics, which can be seen in the financial highlights table on the following page.

Strong Asset Quality – Key credit quality metrics in both commercial and consumer portfolios remained resilient throughout 2025, headlined by non-performing assets of 0.10% of total assets and past due loans of 0.16% of total loans at December 31, 2025. Net charge-offs increased to 0.31% to average loans for 2025, compared to 0.03% for 2024, driven by two charge-offs in our commercial portfolio. The Company considers the two charge-offs in 2025 to be isolated incidents and does not believe they represent a systematic trend within the commercial portfolio.

Strong Capital Position – At December 31, 2025, all of our regulatory capital ratios were well in excess of regulatory capital requirements. Our capital and loan reserve levels, along with our strong credit quality position us for continued success.

Customer Experience Strength– We use net promoter score (“NPS”) to continuously measure and improve customer experience across our retail franchise. Our 2025 aggregate consumer NPS of 68 across Maine remained consistent with prior year and underscores strong customer advocacy relative to industry benchmarks.

Strong Employee Engagement – We measure employee engagement annually through a global, independent third party survey. In 2025, 92% of our employees participated in the confidential survey, reflecting strong engagement across the organization. The Company’s overall engagement score ranked in the 73rd percentile relative to the third-party’s global benchmark, further underscoring the strength of our culture and employee commitment.

Continued Commitment to our Communities – In 2025, we marked Camden National Bank’s 150th anniversary, reflecting a long-standing commitment to the communities we serve. Across our Maine and New Hampshire markets, we continue to support local communities through lending activities, deposit products designed to meet community needs, direct charitable contributions and active employee volunteerism, reinforcing our role as a trusted financial partner and community steward.

Net Interest Income and Net Interest Margin

Net interest income is the interest earned on our lending activities, investment securities and other interest-earning assets, less the interest paid on interest-bearing deposits and borrowings (i.e. our primary business activities). Net interest income, which is our largest source of revenue, accounted for 79%, 75% and 81% of total revenues for the years ended 2025, 2024 and 2023, respectively. Net interest income is affected by factors including, but not limited to, changes in interest rates, loan and deposit pricing strategies and competitive conditions, loan prepayment speeds, the volume and mix of interest-earning assets and interest-bearing liabilities, and the level of non-performing assets.

Net Interest Income. Net interest income on a fully-taxable equivalent basis for the year ended December 31, 2025 was $204.6 million, an increase of 54% from 2024.

Interest income on a fully-taxable equivalent basis for 2025 totaled $322.0 million, representing an increase of $71.8 million, or 29%, compared to 2024, primarily driven by interest-earning assets yield expansion of 37 basis points to 4.99% for the year ended December 31, 2025, and an increase in average interest-earning assets of $1.0 billion, or 19% as of December 31, 2025, which was driven by the Northway acquisition on January 2, 2025. As part of the Northway acquisition, the Company acquired total loans of $775.7 million and investments of $230.0 million. For the year ended December 31, 2025, the Company recognized net fair value mark accretion from the purchase accounting of $20.5 million within interest income, which was made up of $17.0 million of fair value mark accretion on loans and $3.5 million of fair value mark accretion on investments. Additionally, between periods the Company’s yield on interest-earning assets continued to improve organically, contributing to the growth in net interest income, due to the continued reinvestment of cash flows from lower yielding interest-earning assets into new loan originations and investments at prevailing market interest rates.

Interest expense for 2025 increased $294,000, or less than 1%, compared to 2024, despite the increase in average funding liabilities of $1.0 billion, or 20%, which was driven by the Northway acquisition, due to the decrease in our average cost of funds between periods of 38 basis points to 1.90% for the year ended December 31, 2025. The decrease in our average cost of funds between periods reflects the change in the interest rate environment and our ability to lower deposit costs as the Federal Reserve lowered its Federal Funds Rate, and the benefit of adding Northway’s low-cost deposit franchise to the Company’s balance sheet.

Net Interest Margin. Net interest margin is calculated as net interest income on a fully-taxable equivalent basis as a percentage of average interest-earning assets. Our net interest margin on a fully-taxable equivalent basis was 3.17% for the year ended December 31, 2025, compared to 2.46% for 2024. On a non-GAAP basis, adjusted for fair value market accretion income recognized from purchase accounting, our core net interest margin was 2.82% for the year ended December 31, 2025, compared to 2.46% for 2024.

The following table presents, for the periods noted, average balances, interest income, interest expense, and the corresponding average yields earned and rates paid, as well as net interest income, net interest rate spread and net interest margin:

The Company's consolidated financial statements and the notes to the consolidated financial statements presented within have been prepared in accordance with GAAP, which requires the measurement of the financial position and operating results in terms of historical dollars and, in some cases, current fair values without considering changes in the relative purchasing power of money over time due to inflation. Unlike many industrial companies, substantially all of our assets and virtually all of our liabilities are monetary in nature. As a result, interest rates have a more significant impact on our performance than the general level of inflation. Over short periods of time, interest rates and the yield curve may not necessarily move in the same direction or in the same magnitude as inflation.

Provision (Credit) for Credit Losses

The provision (credit) for credit losses was made up of the following components for the periods indicated:

For the Year EndedDecember 31, Change from2025 to 2024

Provision for loan losses. For the year ended December 31, 2025, the Company recorded a provision for loan losses of $22.0 million. The provision primarily reflects the impact of net charge‐offs totaling $16.1 million during the period, driven principally by a $10.7 million partial charge‐off on a syndicated commercial loan participation and a $3.0 million partial charge‐off on a non‐owner‐occupied commercial real estate loan. The recognition of these charge‐offs required the Company to record an incremental $12.7 million in provision for loan loss expense during the year. In addition, in connection with the acquisition of Northway, the Company recorded a $6.3 million provision for loan losses and ACL on loans for the acquired loans that did not meet the criteria to be classified as purchased credit deteriorated (“PCD”) during 2025.

Provision for credit losses on off-balance credit exposures. At December 31, 2025, the ACL on off-balance sheet credit exposures was $3.1 million, as compared to $2.8 million as of December 31, 2024. The Company recorded a provision for credit losses on off-balance sheet credit exposures of $258,000. The 2025 provision was driven by the increase in unfunded credit lines of $43.2 million and the increase in the residential and commercial pipelines of $47.7 million between periods, primarily due to the acquisition of Northway in 2025.

Provision for HTM debt securities: For the year ended December 31, 2025 the Company did not record any provision on HTM debt securities. In the first quarter of 2024, the Company sold a corporate bond issued by Signature Bank that the Company wrote off in 2023 and recovered proceeds of $910,000.

Non-Interest Income

The following table sets forth information regarding non-interest income for the periods indicated:

For the Year EndedDecember 31, Change from2025 to 2024

Net loss on sale of securities — — (10,310) — — %

Non-interest income as a percentage of total revenues(1) 21 % 25 % 19 %

(1) Revenue is the sum of net interest income and non-interest income.

Debit card income represents theinterchange fees earned from debit card transactions of our business and consumer checking account customers, and the annual incentive bonus received from our network provider. The increase in 2025, compared to 2024, was primarily driven by the Northway acquisition, and the resulting addition of approximately 28,000 new debit card customers.

Service charges on deposit accounts represents the fees earned from providing various services to deposit customers, including overdraft, normal fees for servicing deposit accounts, and cash management fees for business customers. The increase in 2025, compared to 2024, was primarily driven by the Northway acquisition, and the resulting addition of approximately 50,000 customer accounts.

Income from fiduciary services represents the fees earned for investment advisory and trust services provided by Camden National Wealth Management. The fees earned are primarily a percentage of our clients' assets under management. Assets under management increased 9% during 2025 to $1.3 billion as of December 31, 2025.

Brokerage and insurance commissions represent the fees earned for brokerage services, investment advisory and insurance services provided by the Bank, doing business as Camden Financial Consultants. Assets under administration grew 22% during 2025 to $1.1 billion as of December 31, 2025, driven by overall market performance and the addition of a new team member.

Mortgage banking income, net is generated through the sale of residential mortgage loans to secondary market investors and also includes income recognized upon the sale of residential mortgages in which we maintain the servicing rights creating a mortgage servicing asset, net of related amortization of the capitalized mortgage servicing asset. Our practice has been to sell the servicing rights for residential mortgages originated, except for certain third party relationships that require the Company to service the loan.

The increase in mortgage banking income, net for the year ended December 31, 2025 compared to 2024, was driven by the increase in net gains recognized on residential mortgage loan sales during the period. For the year ended December 31, 2025, we sold $242.4 million of our originated residential mortgages, compared to $221.9 million sold during the same period in 2024.

Bank-owned life insurance represents the change in cash surrender value of the Company's various BOLI policies in place for certain current and former officers of the Company and Bank. The change in cash surrender value reflects the performance of the underlying investments of the policies. The increase in 2025, compared to 2024, was driven by market performance of the underlying investments. BOLI policies for 2025 included the addition of one policy as part of the Northway acquisition. The underlying investments on the acquired policy are tied to the equity markets and are more susceptible to market volatility than policies with more conservative underlying investments.

Net loss on sale of securities represents the net loss recognized upon the sale of investment securities. We did not sell any investment securities during 2025 or 2024.

Other Income includes third party merchant and credit card commissions, customer loan swap fees and other miscellaneous fees and net gains on equity securities.

Non-Interest Expense

The following table sets forth information regarding non-interest expense for the periods indicated:

For the Year EndedDecember 31, Change from2025 to 2024

Ratio of non-interest expense to total revenues 60.53 % 63.24 % 65.75 %

Salaries and employee benefits includes employee wages, commissions, incentives, equity compensation, employer-related taxes, insurance benefits, and certain other employee-related costs, net of direct employee-related costs incurred for loan originations. The increase in salaries and employee benefits expense for 2025 compared to 2024 was driven by the Northway acquisition, which added approximately 100 new employees, and an increase in performance incentive accruals of $1.7 million between periods due to Company financial performance.

Furniture, equipment and data processing includes depreciation expense of capitalized furniture, equipment and data-related costs, and ongoing system and other data processing costs, including outsourced solutions. The increase in furniture, equipment and data processing expense for 2025 compared to 2024 was due to the Northway acquisition, and our continued investment in customer‐facing digital technology platforms during 2025. These investments included enhancements to our digital suite of products offered to customers and upgrades to information security and resiliency systems.

Net occupancy costs include building and property costs associated with the operation of our branches, loan production offices and service centers, including, but not limited to, rent, depreciation, maintenance and related taxes, net of rental income earned from the lease of office space. The increase in net occupancy costs for 2025 compared to 2024 was primarily driven by the Northway acquisition. At December 31, 2025, the Company had 72 branches, compared to 56 as of December 31, 2024.

Merger and acquisition costsinclude transaction‐related expenses such as personnel termination costs, consulting and other professional fees, contract termination and system conversion costs, and other direct acquisition‐related charges. For the years ended December 31, 2025 and 2024, the Company incurred $9.3 million and $1.2 million, respectively, in costs associated with the Northway acquisition.

The following table summarizes Merger-related costs incurred for the year ended December 31, 2025 and 2024:

Personnel termination-related costs $ 4,992 $ —

Consulting, legal and accounting-related costs 1,926 1,041

Contract termination and conversion-related costs 1,018 —

Debit card expense is the cost incurred for the generation of debit card income, including third party switch network provider fees and related data transmission costs, and plastic card costs for the generation of debit cards for checking account customers. The increase in debit card expense for 2025 compared to 2024 was primarily driven by the Northway acquisition and the resulting addition of approximately 28,000 new debit card customers.

Amortization of CDI assets represents the periodic amortization of the Company’s CDI assets arising from the Northway acquisition. The CDI assets recorded in connection with the Northway acquisition totaled $48.1 million, and we estimate the useful life of these CDI assets to be ten years. Refer to Notes 2 and 5 of the consolidated financial statements for additional information.

Consulting and professional fees include third-party consulting services and other professional fees, such as audit and tax services, legal services, and Company and Bank director fees. The increase in consulting and professional fees for 2025 compared to 2024 resulted from the increase in director fees for, and increases due to increases from the Northway acquisition.

Regulatory assessments are the costs incurred and paid to various regulatory agencies, including the FDIC and OCC. Regulatory assessment fees are based on a number of factors, including but not limited to, asset growth, regulator risk assessment and positive or negative trends specific to the financial institution. The increase in regulatory assessment fees for 2025 compared to 2024 was driven by the Northway acquisition and increase in the Company’s total assets.

OREO and collection costs, net include the costs associated with OREO, collection and foreclosure efforts for the Company's loans.

Other expenses include employee-related costs, such as certain SERP and other postretirement benefits expenses; hiring, training, education, meeting and business travel costs; donations and marketing costs; postage, freight and courier costs; and other expenses. The increase in other expenses for 2025 compared to 2024 was primarily attributable to the Northway acquisition and an increase in marketing costs as we support new markets in New Hampshire, costs associated with a former Northway employee’s supplemental retirement plan, and increases in various operating expenses driven by the increased number of locations, customers and employees following the acquisition.

Income Tax Expense

Income tax expense for the years ended December 31, 2025 and 2024 was $13.5 million and $12.5 million, respectively, and our effective income tax rate was 17.2% for 2025 and 19.0% for 2024. The decrease in the Company's effective income tax rate between years was primarily driven by a one-time $2.4 million decrease in income tax expense associated with the remeasurement of the Company’s deferred tax assets and liabilities upon completion of the Northway acquisition, which increased our tax exposure in Massachusetts and New Hampshire. The remeasurement resulted in an increase to the Company’s deferred tax rate in 2025 to 22.8% from 21.5% in 2024.

The Company's deferred tax assets were $51.1 million and $40.0 million at December 31, 2025 and 2024, respectively. The increase in deferred tax assets during 2025 was primarily driven by the net deferred tax assets that were created through purchase accounting as a result of the Northway acquisition, and the aforementioned $2.4 million increase associated with the remeasurement of Company’s deferred tax assets and liabilities.

Although not anticipated as of December 31, 2025, should the Company realize a loss on these investments, the loss would be characterized as an ordinary loss for income tax purposes and not as a capital loss, and thus would not carry restrictions on use of any such loss.

We continuously monitor and assess the need for a valuation allowance on our deferred tax assets, and we determined that no valuation allowance was necessary as of December 31, 2025 or December 31, 2024.

2024 Operating Results as Compared to 2023 Operating Results

Results of operations for the year ended December 31, 2024 compared to the year ended December 31, 2023 can be found in Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of the Company’s 2024 annual report on Form 10-K filed with the SEC on March 7, 2025.

FINANCIAL CONDITION

Cash and Cash Equivalents

Total cash and cash equivalents were $97.5 million as of December 31, 2025, compared to $215.0 million at December 31, 2024. As part of the Northway acquisition, the Company acquired $48.3 million of cash, which was utilized to prepay all $45.0 million of Federal Home Loan Bank of Boston (“FHLBB”) borrowings assumed from Northway, largely offsetting the cash obtained through the acquisition. The Company continues to actively manage its cash balances. Refer to Note 2 of the consolidated financial statements for additional information on the assets and liabilities acquired from Northway.

Included within the Company’s cash and cash equivalents balances at December 31, 2025 and 2024, was cash held in escrow by the FHLBB as collateral posted by the counterparties for our derivatives in a net asset position at each reporting date totaling $7.2 million and $13.2 million, respectively. We and the counterparty manage these cash accounts daily. Refer to Notes 13 and 14 of the consolidated financial statements for additional detail on the Company’s derivatives and collateral.

Investments

The Company utilizes the investment portfolio to manage liquidity, interest rate risk, and regulatory capital, as well as to take advantage of market conditions to generate returns without undue risk. At December 31, 2025 and 2024, the Company’s investment portfolio generally consisted of MBS, CMO, municipal and corporate debt securities, FHLBB and FRB common stock, and mutual funds held in a rabbi trust for purposes of Company executive and director nonqualified retirement plans. We designate our debt securities as AFS or HTM based on our intent and investment strategy and they are carried at fair value and amortized cost, respectively. Our FHLBB and FRB common stock is carried at cost, and our mutual fund investments are carried at fair value. At December 31, 2025 and 2024, total investments were 21% and 20%, respectively, of total assets.

In 2022, we transferred securities from AFS to HTM to help manage our capital position in a rising interest rate environment. The securities were reclassified at fair value at the time of the transfer, which was a non-cash transaction. At December 31, 2025, the net unrealized losses on the transferred securities reported within AOCI were $36.7 million, net of a deferred tax asset of $10.6 million, and the weighted-average life on these securities was 7.3 years. At December 31, 2024, the net unrealized losses on the transferred securities reported within AOCI were $41.8 million, net of a deferred tax asset of $11.4 million and the weighted-average of these securities was 7.9 years.

At December 31, 2025 and 2024, the Company's investments portfolio totaled $1.4 billion and $1.1 billion, respectively, representing an increase of $308.7 million, or 27%, during 2025. The increase was driven by the addition of $230.0 million of investments, net of purchase accounting adjustments, from the Northway acquisition on January 2, 2025, and included debt securities totaling $227.4 million that were designated as AFS and $2.5 million of FHLBB and other corresponding banking relationship common stock. The other drivers for the net change in total investments during 2025 were:

•The sale of $56.4 million of acquired Northway debt securities shortly after the acquisition date to restructure the

combined investment portfolio. These debt securities were sold at fair value, and, thus, no gain or loss was recognized

upon sale;

•The purchase of $236.7 million of debt securities that we designated as AFS, and the purchase of $5.0 million of

subordinated corporate debt securities of another regional financial institution that we designated as HTM;

•Pay downs, calls and maturities of $152.7 million;

•Net amortization and accretion of $8.4 million; and

•The change in the fair value of the Company’s AFS debt securities of $37.0 million.

Our AFS debt securities portfolio, which comprised 64% and 52% of our investment portfolio at December 31, 2025 and 2024, respectively, was carried at fair value using level 2 valuation techniques. Refer to Notes 1 and 22 of the consolidated financial statements for further details on the Company's fair value techniques.

The AFS and HTM debt securities portfolio has limited credit risk due to its composition, which includes securities backed by the U.S. government and government-sponsored agencies, and corporate and municipal bonds that are highly rated by nationally recognized rating agencies. At December 31, 2025 and 2024, the book value of U.S. government and government-sponsored agencies represented approximately 93% and 91%, respectively, of the AFS and HTM debt securities portfolio. The book value of corporate and municipal bonds carrying a credit rating of “AA” or higher at each of December 31, 2025 and 2024 and was 4% and 5%, respectively, of the AFS and HTM debt securities.

Our other investments on the consolidated statements of condition consist of FHLBB, FRB and other correspondent bank common stock. These investments are carried at cost. We are required to maintain a certain level of investment in FHLBB stock based on our level of FHLBB advances, and maintain a certain level of investment in FRB common stock based on the Bank's capital levels. As of December 31, 2025 and 2024, our investment in FHLBB stock totaled $17.7 million and $17.1 million, respectively, and our investment in FRB stock was $8.7 million and $5.4 million, respectively.

Our investments in mutual funds are designated as trading securities and carried at fair value. These investments are held within a rabbi trust and will be used for future payments associated with the Company’s Executive and Director Deferred Compensation Plan. These investments are carried at fair value using level 1 valuation techniques.

The following table sets forth the carrying value of the Company’s investments portfolio along with the percentage distribution as of the dates indicated:

December 31,

Trading Securities (carried at fair value):

Total trading securities 5,747 — % 5,243 — %

AFS Debt Investments (carried at fair value):

Obligations of states and political subdivisions 5,275 — % 5,289 — %

HTM Debt Investments (carried at amortized cost):

Other correspondent bank stock 70 — % — — %

We continuously monitor and evaluate our investment securities portfolio to identify and assess risks within our portfolio, including, but not limited to, the impact of the current rate environment and the related prepayment risk, and credit ratings. The overall mix of debt securities at December 31, 2025 compared to December 31, 2024 remains relatively unchanged and well positioned to provide a stable source of cash flow. The duration of our debt investment securities portfolio at December 31, 2025 was 4.9 years, compared to 5.2 years at December 31, 2024. The weighted average life of our debt securities portfolio at December 31, 2025 was 6.7 years, compared to 7.0 years at December 31, 2024.

The Company’s AFS debt securities that are in an unrealized loss position are assessed to determine if an allowance should be recorded or if a write-down is required. As of and for the years ended December 31, 2025, 2024 and 2023, we did not record

any allowances or write-down any of our AFS debt securities in an unrealized loss position. Refer to Note 1 of the consolidated financial statements for further discussion of our practices and policies, and refer to Note 3 of the consolidated financial statements for additional details of our assessment of the allowance for AFS investments as of December 31, 2025 and 2024.

We assess our HTM debt securities each reporting period to determine if an allowance should be recorded or if a write-down is required. In the first quarter of 2023, we wrote-off a $1.8 million corporate bond issued by Signature Bank due to Signature Bank's failure through provision expense on the consolidated statements of income. This corporate bond was designated as HTM and previously carried no ACL. In January 2024, we sold the Signature Bank security and recovered $910,000. We completed a review of our HTM investment portfolio as of December 31, 2025 and 2024, and concluded that no ACL was warranted on any bonds at this time. Refer to Note 1 of the consolidated financial statements for further discussion of our practices and policies, and refer to Note 3 of the consolidated financial statements for additional details of our assessment of the allowance for HTM investments as of December 31, 2025 and 2024.

The fair value and book value of the Company's corporate bonds and municipal securities as of December 31, 2025 and 2024 was as follows:

At December 31, 2025 and 2024, municipal bonds were 4% and 5%, respectively, of the book value of the total bond portfolio. At December 31, 2025 and 2024, all municipal bonds carried an investment-grade credit rating.

At December 31, 2025 and 2024, corporate bonds were 3% of the book value of the total bond portfolio. At December 31, 2025 and 2024, corporate bonds with a book value of $26.0 million and $25.9 million, or 68% and 70% of the corporate bond portfolio, carried an investment-grade credit rating. The remaining corporate bonds with a book value of $12.2 million and $11.2 million at December 31, 2025 and 2024, respectively, were non-rated corporate bonds of community banks within our markets. As of December 31, 2025, the corporate bond portfolio was made up of 17 different companies, which included 15 different banks. The banks in the portfolio range from the largest U.S. banks to community banks, with 34% of our exposure as of December 31, 2025, being to global systemically important banks, or "G-SIBs." We continue to monitor and analyze the performance of our corporate bond portfolio.
