Forward-Looking Statements

This report contains statements that are "forward-looking statements." We may also make written or oral forward-looking statements in other documents we file with the SEC, in our annual reports to shareholders, in press releases and other written materials, and in oral statements made by our officers, directors or employees. You can identify forward-looking statements by the use of the words "believe," "expect," "anticipate," "intend," "estimate," "assume," "outlook," "will," "should," and other expressions that predict or indicate future events and trends and which do not relate to historical matters. You should not rely on forward-looking statements, because they involve known and unknown risks, uncertainties and other factors, some of which are beyond the control of the Company. These risks, uncertainties and other factors may cause the actual results, performance or achievements of the Company to be materially different from the anticipated future results, performance or achievements expressed or implied by the forward-looking statements.

Some of the factors that might cause these differences include the following: changes in general national, regional or international economic conditions or conditions affecting the banking or financial services industries or financial capital markets, volatility and disruption in national and international financial markets, government intervention in the U.S. financial system, reductions in net interest income resulting from interest rate volatility as well as changes in the balance and mix of loans and deposits, reductions in the market value of wealth management assets under administration, changes in the value of securities and other assets, reductions in loan demand, changes in loan collectability, default and charge-off rates, changes in the size and nature of the Company's competition, changes in legislation or regulation and accounting principles, policies and guidelines, and changes in the assumptions used in making such forward-looking statements. In addition, the factors described under "Risk Factors" in Item 1A of this Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as filed with the SEC, may result in these differences, as well as the "Risk Factors" in Part II, Item 1A listed below. You should carefully review all of these factors, and you should be aware that there may be other factors that could cause these differences. These forward-looking statements were based on information, plans and estimates at the date of this quarterly report, and we assume no obligation to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events or other changes.

Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, actual results may differ materially from the results discussed in these forward-looking statements. Readers are also urged to carefully review and consider the various disclosures made by the Company, which attempt to advise interested parties of the factors that affect the Company's business.

Critical Accounting Policies

Management's discussion and analysis of the Company's financial condition and results of operations is based on the consolidated financial statements which are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of such financial statements requires Management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, Management evaluates its estimates, including those related to the ACL, fair value of securities, goodwill, the valuation of mortgage servicing rights, derivative financial instruments, and credit losses on securities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets that are not readily apparent from other sources. Actual results could differ from the amounts derived from Management's estimates and assumptions under different assumptions or conditions.

Allowance for Credit Losses. Management believes the ACL requires the most significant estimates and assumptions used in the preparation of the consolidated financial statements. The ACL is based on Management's evaluation of the level of the allowance required in relation to the estimated loss exposure in the loan portfolio, off-balance sheet commitments, and investment portfolio.

Management regularly evaluates the allowance, typically monthly, to determine the appropriate level by taking into consideration factors such as the size and growth trajectory of the portfolio, quality trends as measured by key indicators, prior loan loss experience in major portfolio segments, local and national business conditions, economic forecasts, the results of any stress testing undertaken during the period, and Management's estimation of potential losses. Period-to-period changes to any or all of these of these factors could change the level of ACL required, in turn impacting our level of provision expense and ultimately our net income. Similarly, the use of different estimates or assumptions could produce different provisions for credit losses which would likely result in changes to the Company's net income.

In the three months ended March 31, 2026 the ACL-Loans decreased by $156,000, the ACL-Off-Balance Commitments decreased by $29,000 and the ACL-HTM Securities decreased by $1,000. Further discussion of the ACL may be found in Note 2, "Investment Securities", Note 3, "Loans", and Note 4, "Allowance for Credit Losses", to the consolidated financial statements contained in Item 1 of the Form 10-Q.

Goodwill. Management utilizes numerous techniques to estimate the value of various assets held by the Company, including methods to determine the appropriate carrying value of goodwill as required under FASB ASC Topic 350 "Intangibles – Goodwill and Other." In addition, goodwill from a purchase acquisition is subject to ongoing periodic impairment tests, which include an evaluation of the ongoing assets, liabilities and revenues from the acquisition and an estimation of the impact of business conditions.

Fair Value of Securities. Determining a market price for securities carried at fair value is a critical accounting estimate in the Company's financial statements. Pricing of individual securities is subject to a number of factors including changes in market interest rates, changes in prepayment speeds and assumptions, changes in market tolerance for risk, and any changes in the risk profile of the security. The Company subscribes to a widely recognized, independent pricing service and updates carrying values no less frequently than monthly. It also validates the values provided by the pricing service no less frequently than quarterly by measuring against security prices provided by a secondary source. Results of the validation are reported to the ALCO each quarter and any variances between the two sources above defined thresholds are investigated by management. A finding that the Company's methodology for valuation of its investment securities is materially incorrect could result in changes to the carrying value of securities on its balance sheet and corresponding changes in shareholders equity position. As of March 31, 2026 the fair value of AFS securities decreased by $7.7 million and the fair value of HTM securities decreased by $6.8 million from that of December 31, 2025. The decrease in the fair value of AFS securities is attributable to a combination of rate-driven market price adjustments for the underlying securities, principal returned via maturity, call, sale, or amortization, and new purchases. The decrease in the fair value of HTM securities is primarily attributable to rate-driven price adjustments for the underlying securities, along with principal return via call or maturity. Further discussion of the fair value of securities may be found in Note 2, "Investment Securities", to the consolidated financial statements contained in Item 1 of the Form 10-Q.

Credit Loss Recognition on Securities. Another significant estimate related to investment securities is the evaluation of potential credit losses on investment securities. The evaluation of securities for potential credit losses is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the fair value of investments should be recognized as a charge to the ACL. The risks and uncertainties include changes in general economic conditions, the issuer's financial condition and/or future prospects, the effects of changes in interest rates or credit spreads and the expected recovery period of unrealized losses. Securities that are in an unrealized loss position are reviewed at least quarterly to determine if recognition of a loss is required. The primary factors considered in this evaluation (a) the length of time and extent to which the fair value has been less than cost or amortized cost and the expected recovery period of the security, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments, (d) the volatility of the securities' market price, (e) the intent and ability of the Company to retain the investment for a period of time sufficient to allow for recovery, which may be at maturity and (f) any other information and observable data considered relevant, including the expectation of receipt of all principal and interest when due. The Bank invests only in investment grade securities and no credit losses have been recognized on securities currently held. Further discussion of credit loss recognition on securities may be found in Note 2, "Investment Securities", to the consolidated financial statements contained in Item 1 of the Form 10-Q.

Derivative Financial Instruments Designated as Hedges. The Company recognizes all derivatives in the consolidated balance sheets at fair value. On the date a derivative contract is entered into, the derivative is designated as a hedge of either a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), or a held for trading instrument (“trading instrument”). The relationships between hedging instruments and hedged items is formally documented, as is the risk management objectives and strategy for undertaking various hedge transactions. Both at the hedge’s inception and on an ongoing basis, determination is made as to whether the derivatives that are used in hedging transactions are effective in offsetting changes in cash flows or fair values of hedged items. Changes in fair value of a derivative that is effective and that qualifies as a cash flow hedge are recorded in OCI and are reclassified into earnings when the forecasted transaction or related cash flows affect earnings. Changes in fair value of a derivative that qualifies as a fair value hedge and the change in fair value of the hedged item are both recorded in earnings and offset each other when the transaction is effective. Those derivatives that are classified as trading instruments, including customer loan swaps, are recorded at fair value with changes in fair value recorded in earnings. Hedge accounting is dis

ITEM 7. Management's Discussion and Analysis of Financial Condition and Results of Operations

The Company was incorporated in the State of Maine on January 15, 1985, and is the parent holding company of the Bank. On January 28, 2016, the Board of Directors voted to change the Bank's name to First National Bank from The First, N.A.

The Company generates almost all of its revenues from the Bank, which was chartered as a national bank under the laws of the United States on May 30, 1864. The Bank, which has eighteen offices along coastal and eastern Maine, emphasizes personal service to the communities it serves, concentrating primarily on small businesses and individuals.

The Bank offers a wide variety of traditional banking services and derives the majority of its revenues from net interest income – the spread between what it earns on loans and investments and what it pays for deposits and borrowed funds. While net interest income typically increases as earning assets grow, the spread can vary up or down depending on the level and direction of movements in interest rates. Management believes the Bank has moderate exposure to changes in interest rates, as discussed in "Interest Rate Risk Management" elsewhere in Management's Discussion.

Non-interest income is the Bank's secondary source of revenue and includes fees and service charges on deposit accounts and services, interchange from debit cards, income from the sale and servicing of mortgage loans, and income from investment management and private banking services through First National Wealth Management (previously First Advisors), a division of the Bank.

The abbreviations and descriptions identified below may be used throughout Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operation and Item 8 - Financial Statement and Supplementary Data. The following is provided to aid the reader and provide a reference page when reviewing these sections of the Form 10-K.

Forward-Looking Statements

This report contains statements that are "forward-looking statements." We may also make written or oral forward-looking statements in other documents we file with the SEC, in our annual reports to shareholders, in press releases and other written materials, and in oral statements made by our officers, directors or employees. You can identify forward-looking statements by the use of the words "believe," "expect," "anticipate," "intend," "estimate," "assume," "outlook," "will," "should," and other expressions that predict or indicate future events and trends and which do not relate to historical matters. You should not rely on forward-looking statements, because they involve known and unknown risks, uncertainties and other factors, some of which are beyond the control of the Company. These risks, uncertainties and other factors may cause the actual results, performance or

achievements of the Company to be materially different from the anticipated future results, performance or achievements expressed or implied by the forward-looking statements.

Some of the factors that might cause these differences include the following: changes in general national, regional or international economic conditions or conditions affecting the banking or financial services industries or financial capital markets, volatility and disruption in national and international financial markets, government intervention in the U.S. financial system, reductions in net interest income resulting from interest rate volatility as well as changes in the balance and mix of loans and deposits, reductions in the market value of wealth management assets under administration, changes in the value of securities and other assets, reductions in loan demand, changes in loan collectability, default and charge-off rates, changes in the size and nature of the Company's competition, changes in legislation or regulation and accounting principles, policies and guidelines, and changes in the assumptions used in making such forward-looking statements. In addition, the factors described under "Risk Factors" in Item 1A of this Annual Report on Form 10-K may result in these differences. You should carefully review all of these factors, and you should be aware that there may be other factors that could cause these differences. These forward-looking statements were based on information, plans and estimates at the date of this annual report, and we assume no obligation to update any forward-looking statements to reflect changes in underlying assumptions or factors, new information, future events or other changes.

Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, actual results may differ materially from the results discussed in these forward-looking statements. Readers are also urged to carefully review and consider the various disclosures made by the Company, which attempt to advise interested parties of the factors that affect the Company's business.

Critical Accounting Policies and Estimates

The Company's significant accounting policies are described in Note 1, "Summary of Significant Accounting Policies," to the consolidated financial statements contained in Item 8, "Financial Statements and Supplementary Data," of this Form 10-K. In applying these accounting policies, management is required to exercise judgment in determining many of the methodologies, assumptions and estimates to be utilized. Certain of the critical accounting estimates are more dependent on such judgment and in some cases may contribute to volatility in the Company's reported financial performance should the assumptions and estimates used be incorrect or change over time due to changes in circumstances.

Management's discussion and analysis of the Company's financial condition and results of operations is based on the consolidated financial statements which are prepared in accordance with accounting principles generally accepted in the United States of America. The preparation of such financial statements requires Management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, Management evaluates its estimates, including those related to the ACL, fair value of securities, goodwill, the valuation of mortgage servicing rights, derivative financial instruments, and other-than-temporary impairment on securities. Management bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets that are not readily apparent from other sources. Actual results could differ from the amounts derived from Management's estimates and assumptions under different assumptions or conditions.

Allowance for Credit Losses. Management believes the ACL requires the most significant estimates and assumptions used in the preparation of the consolidated financial statements. The ACL is based on Management's evaluation of the level of the allowance required in relation to the estimated loss exposure in the loan portfolio, off-balance sheet commitments, and investment portfolio.

Management regularly evaluates the allowance, typically monthly, to determine the appropriate level by taking into consideration factors such as the size and growth trajectory of the portfolio, quality trends as measured by key indicators, prior loan loss experience in major portfolio segments, local and national business conditions, economic forecasts, the results of any stress testing undertaken during the period, and Management's estimation of potential losses. Period-to-period changes to any or all of these of these factors could change the level of ACL required, in turn impacting our level of provision expense and ultimately our net income. Similarly, the use of different estimates or assumptions could produce different provisions for credit losses which would likely result in changes to the Company's net income. In the12 months ended December 31, 2025, the ACL-Loans increased by $494,000, the ACL-Off-Balance Commitments decreased by $149,000 and the ACL-HTM Securities decreased by $50,000. Further discussion of the ACL may be found in Note 3, "Investment Securities", Note 5, "Loans" and Note 6, "Allowance for Credit Losses", to the consolidated financial statements contained in Item 8 of the Form 10-K.

Fair Value of Securities. Determining a market price for securities carried at fair value is a critical accounting estimate in the Company's financial statements. Pricing of individual securities is subject to a number of factors including changes in market interest rates, changes in prepayment speeds and assumptions, changes in market tolerance for risk, and any changes in the risk profile of the security. The Company subscribes to a widely recognized, independent pricing service and updates carrying values no less frequently than monthly. It also validates the values provided by the pricing service no less frequently than quarterly by measuring against security prices provided by a secondary source. Results of the validation are reported to the ALCO each quarter and any variances between the two sources above defined thresholds are investigated by management. A finding that the Company's methodology for valuation of its investment securities is materially incorrect could result in changes to the carrying value of securities on its balance sheet and corresponding changes in shareholders equity position. As of December 31, 2025 the fair value of AFS securities decreased by $10.2 million and the fair value of HTM securities increased by $489,000 from that of December 31, 2024. These changes are due to a combination of rate-driven market price adjustments for the underlying securities and reinvestment of incoming cash flow to other segments of the balance sheet. Further discussion of the fair value of securities may be found in Note 3, "Investment Securities", to the consolidated financial statements contained in Item 8 of the Form 10-K.

Credit Loss Recognition on Securities. Another significant estimate related to investment securities is the evaluation of potential credit losses on investment securities. The evaluation of securities for potential credit losses is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether declines in the fair value of investments should be recognized as a charge to the allowance for credit losses. The risks and uncertainties include changes in general economic conditions, the issuer's financial condition and/or future prospects, the effects of changes in interest rates or credit spreads and the expected recovery period of unrealized losses. Securities that are in an unrealized loss position are reviewed at least quarterly to determine if recognition of a loss is required. The primary factors considered in this evaluation (a) the length of time and extent to which the fair value has been less than cost or amortized cost and the expected recovery period of the security, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments, (d) the volatility of the securities' market price, (e) the intent and ability of the Company to retain the investment for a period of time sufficient to allow for recovery, which may be at maturity and (f) any other information and observable data considered relevant, including the expectation of receipt of all principal and interest when due. The Bank invests only in investment grade securities and no credit losses have been recognized on securities currently held. Further discussion of credit loss recognition on securities may be found in Note 3, "Investment Securities", to the consolidated financial statements contained in Item 8 of the Form 10-K.

Goodwill. Management utilizes numerous techniques to estimate the value of various assets held by the Company, including methods to determine the appropriate carrying value of goodwill as required under FASB ASC Topic 350 "Intangibles – Goodwill and Other." In addition, goodwill from a purchase acquisition is subject to ongoing periodic impairment tests, which include an evaluation of the ongoing assets, liabilities and revenues from the acquisition and an estimation of the impact of business conditions. Testing has indicated that no impairment of goodwill has occurred and the value of goodwill as of December 31, 2025 is unchanged from the prior year.

Mortgage Servicing Rights. The valuation of mortgage servicing rights is a critical accounting policy which requires significant estimates and assumptions. The Bank often sells mortgage loans it originates and retains the ongoing servicing of such loans, receiving a fee for these services, generally 0.25% of the outstanding balance of the loan per annum. Mortgage servicing rights are recognized at fair value when they are acquired through the sale of loans, and are reported in other assets. They are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. The rights are subsequently carried at the lower of amortized cost or fair value. Management uses an independent firm which specializes in the valuation of mortgage servicing rights to determine the fair value. The most important assumption is the anticipated loan prepayment rate, and increases in prepayment speed and amount result in lower valuations of mortgage servicing rights. The valuation also includes an evaluation for impairment based upon the fair value of the rights, which can vary depending upon current interest rates and prepayment expectations, as compared to amortized cost. Impairment is determined by stratifying rights by predominant characteristics, such as interest rates and terms. The fair value of mortgage servicing rights as of December 31, 2025 decreased by $369,000 from that of December 31, 2024 primarily due to loan amortization and payoffs outpacing sales of new loans during the year, and no impairment was recognized as of either date. The use of different assumptions could produce a different valuation. All of the assumptions are based on standards the Company believes would be utilized by market participants in valuing mortgage servicing rights and are consistently derived and/or benchmarked against independent public sources. Further information may be found in Note 4, "Mortgage Servicing Rights", to the consolidated financial statements contained in Item 8 of the Form 10-K.

Derivative Financial Instruments Designated as Hedges. The Company recognizes all derivatives in the consolidated balance sheets at fair value. On the date a derivative contract is entered into, the derivative is designated as a hedge of either a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (“cash flow hedge”), a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (“fair value hedge”), or a held for trading instrument (“trading instrument”). The relationships between hedging instruments and hedged items is formally documented, as is the risk management objectives and strategy for undertaking various hedge transactions. Both at the hedge’s inception and on an ongoing basis, determination is made as to whether the derivatives that are used in hedging transactions are effective in offsetting changes in cash flows or fair values of hedged items. Changes in fair value of a derivative

The First Bancorp - 2025 Form 10-K - Page 24

that is effective and that qualifies as a cash flow hedge are recorded in OCI and are reclassified into earnings when the forecasted transaction or related cash flows affect earnings. Changes in fair value of a derivative that qualifies as a fair value hedge and the change in fair value of the hedged item are both recorded in earnings and offset each other when the transaction is effective. Those derivatives that are classified as trading instruments, including customer loan swaps, are recorded at fair value with changes in fair value recorded in earnings. Hedge accounting is discontinued when it is determined that the derivative is no longer effective in offsetting changes in the cash flows of the hedged item, that it is unlikely that the forecasted transaction will occur, or that the designation of the derivative as a hedging instrument is no longer appropriate. Among the factors that may influence the fair value of a derivative instrument are changes in market interest rates, changes in the time remaining to maturity of the instrument, or credit quality of the counter-party. Further information, including period-to-period changes in the fair value of derivatives, may be found in Note 14, "Financial Derivative Instruments", to the consolidated financial statements contained in Item 8 of the Form 10-K.

Use of Non-GAAP Financial Measures

Certain information in Management's Discussion and Analysis of Financial Condition and Results of Operations and elsewhere in this Report contains financial information determined by methods other than in accordance with GAAP. Management uses these “non-GAAP” measures in its analysis of the Company's performance (including for purposes of determining the compensation of certain executive officers and other Company employees) and believes that these non-GAAP financial measures provide a greater understanding of ongoing operations and enhance comparability of results with prior periods and with other financial institutions, as well as demonstrating the effects of significant gains and charges in the current period, in light of the disclosure practices employed by many other publicly-traded financial institutions. The Company believes that a meaningful analysis of its financial performance requires an understanding of the factors underlying that performance. Management believes that investors may use these non-GAAP financial measures to analyze financial performance without 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 operating results determined in accordance with GAAP, nor are they necessarily comparable to non- GAAP performance measures that may be presented by other companies.

In several places net interest income is calculated on a fully tax-equivalent basis. Specifically included in interest income was tax-exempt interest income from certain investment securities and loans. An amount equal to the tax benefit derived from this tax-exempt income has been added back to the interest income total which, as adjusted, increased net interest income accordingly. Management believes the disclosure of tax-equivalent net interest income information improves the clarity of financial analysis, and is particularly useful to investors in understanding and evaluating the changes and trends in the Company's results of operations. Other financial institutions commonly present net interest income on a tax-equivalent basis. This adjustment is considered helpful in the comparison of one financial institution's net interest income to that of another institution, as each will have a different proportion of tax-exempt interest from its earning assets. Moreover, net interest income is a component of a second financial measure commonly used by financial institutions, net interest margin, which is the ratio of net interest income to average earning assets. For purposes of this measure as well, other financial institutions generally use tax equivalent net interest income to provide a better basis of comparison from institution to institution. The Company follows these practices.

The following table provides a reconciliation of tax-equivalent financial information to the Company's consolidated financial statements prepared in accordance with GAAP. A Federal income tax rate of 21.0% was used in 2025 and 2024.

The Company presents its efficiency ratio using non-GAAP information which is most commonly used by financial institutions. The GAAP-based efficiency ratio is noninterest expenses divided by net interest income plus noninterest income from the Consolidated Statements of Income and Comprehensive Income. The non-GAAP efficiency ratio excludes securities losses from noninterest expenses, excludes securities gains from noninterest income, and adds the tax-equivalent adjustment to net interest income.

The First Bancorp - 2025 Form 10-K - Page 25

The following table provides a reconciliation between the GAAP and non-GAAP efficiency ratio:

The Company presents certain information based upon average tangible common shareholders' equity instead of total average shareholders' equity. The difference between these two measures is the Company's intangible assets, specifically goodwill from prior acquisitions. Management, banking regulators and many stock analysts use the tangible common equity ratio and the tangible book value per common share in conjunction with more traditional bank capital ratios to compare the capital adequacy of banking organizations with significant amounts of goodwill or other intangible assets, typically stemming from the use of the purchase accounting method in accounting for mergers and acquisitions.

The following table provides a reconciliation of average tangible common shareholders' equity to the Company's consolidated financial statements, which have been prepared in accordance with GAAP:

To provide period-to-period comparison of operating results prior to consideration of credit loss provision and income taxes, the non-GAAP measure of PTPP Net Income is presented. The following table provides a reconciliation to Net Income:

Executive Summary

The Company reported net income for the year ended December 31, 2025 of $34.4 million, up $7.3 million or 27.2% from $27.0 million reported for the year ended December 31, 2024. Earnings per common share on a fully diluted basis were $3.07 and $2.43, respectively, for the same periods, up $0.64 or 26.3%.

Earnings for the Company rebounded strongly in 2025. Net interest margin expansion, which began in the second half of 2024, continued and accelerated throughout 2025 leading to a significant increase in net income interest income and ultimately improved bottom-line profitability for the Bank and Company. Margin expansion was achieved via a focus on generation of lower-cost local deposits to replace higher-cost wholesale sources, scheduled re-pricing of legacy earning assets, targeted origination of new earning assets, and pricing discipline on both sides of the balance sheet.

During 2025, total assets increased $9.3 million or 0.3%, ending the year at $3.166 billion. The loan portfolio increased $53.2 million or 2.3% in 2025, ending the year at $2.394 billion. The investment portfolio was down $22.9 million or 3.5% as cash flow from matured and amortizing securities was redeployed to other segments of the balance sheet rather than reinvested. On the liability side of the balance sheet, core deposits increased $77.0 million or 4.8%, to $1.687 billion as of December 31, 2025. Certificates of deposit decreased $137.5 million or 12.3% from the end of 2024.  Local CDs decreased $12.2 million and wholesale CDs decreased $125.3 million at December 31, 2025 compared to December 31, 2024.

Asset quality continues to be favorable. Non-performing loans stood at 0.54% of total loans as of December 31, 2025 up from 0.18% of non-performing loans a year ago, but remaining below long-term averages. Net chargeoffs were $1.6 million, or 0.07% of average loans in 2025, compared to $463,000, or 0.02% of average loans for the year ended December 31, 2024. Past due loans were 0.90% of total loans as of December 31, 2025, an increase from 0.40% of total loans at December 31, 2024. The allowance as a percentage of loans outstanding stood at 1.06% in 2025, level with December 31, 2024. The provision for credit losses on loans was $2.0 million in 2025, as compared to $1.3 million in 2024.

The Company's capital position improved in 2025, the result of improved profitability and a slower rate of balance sheet expansion as compared to the prior several years. The Company's total risk-based capital ratio was 14.02% as of December 31, 2025, solidly above the well-capitalized threshold of 10.0% set by the FDIC, the FRB, and the OCC.

On a tax-equivalent basis, net interest income increased $13.5 million or 20.3% for the year ended December 31, 2025 compared to the year ended December 31, 2024. Total interest income increased $11.4 million, or 7.7%, from 2024, while total interest expense decreased $2.0 million, or 2.4%. The Company's tax-equivalent net interest margin was 2.63% in 2025, compared to 2.29% in 2024. Net interest margin by quarter was 2.48%, 2.52%, 2.70% and 2.83% for the first through fourth quarters of 2025, respectively, as compared to 2.22%, 2.21%, 2.32%, and 2.42% in the same periods of 2024.

Non-interest income in 2025 was $17.3 million, an increase of $985,000 or 6.0% from the $16.4 million reported in 2024. The year-to-year increase in non-interest income is primarily attributable to Wealth Management revenue growth of $464,000 or 9.3% from 2024, and an increase in other operating income of $357,000 or 11.5%, during the same period.

Non-interest expense in 2025 was $50.9 million, an increase of $3.8 million or 8.0% from the $47.2 million reported in 2024. Employee salary and benefit expense increased $2.8 million or 11.4% from the prior year. Asset growth and premium calculation variances led to a $331,000 increase in deposit insurance premiums from the prior year. Income taxes on operating earnings were $7.5 million for the year ended December 31, 2025, up $2.0 million from the same period in 2024.

Improved earnings performance led to a corresponding improvement in the Company's operating ratios. Return on average assets of 1.08% and a return on average tangible common equity (non-GAAP) of 14.50% for the year ended December 31, 2025, compare favorably to 0.89% and 12.35%, respectively, for the prior year. Our non-GAAP efficiency ratio continues to be an important component in our overall performance and improved to 52.09% for 2025. Dividends paid to shareholders totaled $1.47 per share, representing 47.39% of basic earnings per share for the year.

Net interest income on a tax-equivalent basis increased 20.3% or $13.5 million to $80.2 million for the year ended December 31, 2025 from the $66.7 million reported for the year ended December 31, 2024. The Company's net interest margin was 2.63% in 2025, compared to 2.29% in 2024.

Total interest income on a tax-equivalent basis in 2025 was $163.1 million, an increase of $11.5 million or 7.6% from the $151.6 million posted by the Company in 2024. A shift in earning asset composition from investments to higher-yielding loans

coupled with higher interest rates on both new loans and re-priced legacy transactions contributed to the increase in interest income. Total interest expense in 2025 was $82.9 million, a decrease of $2.0 million or 2.4% from the $84.9 million posted by the Company in 2024. Generally lower market interest rates resulting from FOMC actions coupled with growth in local deposits that allowed for a reduction in higher-cost wholesale funding each contributed to the interest expense decrease. Tax-exempt interest income amounted to $10.7 million for the year ended December 31, 2025, and $10.5 million for the year ended December 31, 2024.

The following table presents changes in interest income and expense attributable to changes in interest rates, volume, and rate/volume1 for interest-earning assets and interest-bearing liabilities. Tax-exempt income is calculated on a tax-equivalent basis, using a 21.0% Federal income tax rate in 2025 and 2024.

1 Represents the change attributable to a combination of change in rate and change in volume.

The following table presents the interest earned on or paid for each major asset and liability category, respectively, for the years ended December 31, 2025 and 2024, as well as the average yield for each major asset and liability category, and the net yield between assets and liabilities. Tax-exempt income has been calculated on a tax-equivalent basis using a 21% Federal income tax rate in 2025 and 2024. Unrecognized interest on non-accrual loans is not included in the amount presented, but the average balance of non-accrual loans is included in the denominator when calculating yields.

The First Bancorp - 2025 Form 10-K - Page 29

Non-Interest Income

Non-interest income in 2025 was $17.3 million, an increase of $985,000 or 6.0% from the $16.4 million reported in 2024. The year-to-year increase in non-interest income is primarily attributable to Wealth Management revenue growth of $464,000 or 9.3% from 2024, and an increase in other operating income of $357,000 or 11.5%, during the same period. Mortgage banking revenue increased $52,000 or 6.5% from 2024 and service charge revenues increased $113,000, or 5.5% year-over-year.

Non-Interest Expense

Non-interest expense in 2025 was $50.9 million, an increase of $3.8 million or 8.0% from the $47.2 million reported in 2024. Employee salary and benefit expense increased $2.8 million or 11.4% from the prior year, attributable to a combination of salary adjustments, incentive compensation accruals, increased benefit costs, and several one-time expenses resulting from retirements. FDIC insurance premiums increased by $331,000 attributable to various factor changes in the premium calculation. Furniture and equipment expense was up $256,000 or 4.6% on higher software costs, and other operating expense increased $396,000 or 3.4%. from 2024.

Provision to the Allowance for Credit Losses Loans

The Company's provision to the ACL loans was $2.0 million in 2025, up from $1.3 million provisioned in 2024. The ACL loans stood at 1.06% of total loans as of December 31, 2025, compared to 1.06% as of December 31, 2024.

Net loan charge-offs in 2025 were $1.6 million or 0.07% of average loans, up from $463,000 or 0.02% of loans in 2024. Non-performing assets stood at 0.41% of total assets as of December 31, 2025 compared to 0.14% of total assets at December 31, 2024. The change in non-performing assets is primarily centered in two credit relationships in which resolution activities have commenced and against which specific reserves have been established. Past-due loans were 0.90% of total loans as of December 31, 2025, an increase from 0.40% of total loans as of December 31, 2024.

Income Taxes

Income taxes on operating earnings were $7.5 million for the year ended December 31, 2025, up $2.0 million from 2024.

Net Income

Net income for 2025 was $34.4 million, up 27.2% or $7.3 million from net income of $27.0 million that was posted in 2024. Earnings per share on a fully diluted basis for 2025 were $3.07, up $0.64 or 26.3% from the $2.43 reported for the year ended December 31, 2024.

Key Ratios

Return on average assets in 2025 was 1.08%, up from the 0.89% posted in 2024. Return on average tangible common equity was 14.50% in 2025, compared to 12.35% in 2024. In 2025, the Company's dividend payout ratio (dividends declared per share divided by earnings per share) was 47.39%, compared to 58.44% in 2024. The Company's non-GAAP efficiency ratio – a benchmark measure of the amount spent to generate a dollar of income – was 52.09% in 2025, compared to 56.66% in 2024.

Investment Management and Fiduciary Activities

As of December 31, 2025, First National Wealth Management, the Bank's trust and investment management division, had assets under management or custody with a market value of $1.384 billion, consisting of 1,306 trust accounts, estate accounts, agency accounts, and self-directed individual retirement accounts. This compares to December 31, 2024, when 1,272 accounts with a market value of $1.290 billion were under management or custody.

Comparison of the Years Ended December 31, 2024 and 2023

A discussion of changes in our results of operations during the year ended December 31, 2024 compared to the year ended December 31, 2023 has been omitted from this Annual Report on Form 10-K but may be found in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 7, 2025, which discussion is incorporated herein by reference, and which is available free of charge on the SECs website at www.sec.gov.

Assets and Asset Quality

Total assets of $3.166 billion at December 31, 2025 increased 0.3% or $9.3 million from $3.157 billion at December 31, 2024. The investment portfolio, including restricted equity securities decreased $22.9 million or 3.5% over December 31, 2024, and the loan portfolio increased $53.2 million or 2.3%. Year-over-year, average assets were up $138.8 million in 2025 over 2024. Average loans in 2025 were $150.6 million higher than in 2024, and average investments in 2025 were $14.1 million lower than in 2024.

Non-performing assets to total assets stood at 0.41% at December 31, 2025, up from the 0.14% of total assets at December 31, 2024. In general terms, the Company's long-standing approach to working with borrowers and ethical loan underwriting standards helps alleviate some of the payment problems on customers' loans and minimizes actual loan losses, in Management's opinion. There was no OREO or related allowance at December 31, 2025. The company held one OREO property with a carrying value of $173,000, net of an allowance of $35,000 on December 31, 2024.

Net chargeoffs in 2025 were $1.6 million or 0.07% of average loans outstanding, up $1.1 million from 2024. Residential real estate term loans represent 30.9% of the total loan portfolio, and this loan category generally has a lower level of losses in comparison to other loan types. In 2025, residential mortgages had a net recovery of 0.001% compared to a loss ratio of 0.065% for the entire loan portfolio. The Company does not have a credit card portfolio or offer dealer consumer loans, which generally carry more risk and potentially higher losses than other types of consumer credit.

The ACL-loans ended 2025 at $25.4 million and stood at 1.06% of total loans outstanding, compared to $24.9 million and 1.06% of total loans outstanding at December 31, 2024. A $2.0 million provision for losses was made during the year ended 2025.

Investment Activities

During 2025, the investment portfolio, including restricted equity securities, decreased 3.5% to end the year at $628.7 million, compared to $651.6 million at December 31, 2024. Average investments in 2025 were $14.1 million lower than in 2024. The change in value of the portfolio is attributable primarily to limited reinvestment of incoming cash flow from amortizing and matured investments, as cash flow was re-directed to other segments of the balance sheet. As of December 31, 2025, mortgage-backed securities had a carrying value of $259.0 million and a fair value of $250.2 million. Of this total, securities with a fair value of $64.5 million or 25.8% of the mortgage-backed portfolio were issued by the GNMA and securities with a fair value of $185.7 million or 74.2% of the mortgage-backed portfolio were issued by the FHLMC and the FNMA.

The Company's investment securities are classified into three categories: securities available for sale, securities to be held to maturity and restricted equity securities. Securities available for sale consist primarily of debt securities which Management intends to hold for indefinite periods of time. They may be used as part of the Company's funds management strategy, and may be sold in response to changes in interest rates, prepayment risk and liquidity needs, to increase capital ratios, or for other similar reasons. Securities to be held to maturity consist primarily of debt securities that the Company has acquired solely for long-term investment purposes, rather than for trading or future sale. For securities to be categorized as HTM, Management must have the intent and the Company must have the ability to hold such investments until their respective maturity dates. Restricted equity securities consist of investments in the stock of the FRBB and the FHLBB; ownership of these securities is required as a condition of the Bank's membership in the respective banks and these shares are not able to be pledged or sold. The Company does not hold trading account securities.

All investment securities are managed in accordance with a written investment policy adopted by the Board of Directors. It is the Company's general policy that investments for either the AFS or HTM portfolio be limited to government debt obligations, time deposits, and corporate bonds or commercial paper with one of the three highest ratings given by a nationally recognized rating agency. The portfolio is currently invested primarily in U.S. Government sponsored agency securities, mortgage-backed securities and tax-exempt obligations of states and political subdivisions. The individual securities have been selected to enhance the portfolio's overall yield while not materially adding to the Company's level of interest rate risk.

During the third quarter of 2014, the Company transferred securities with a total amortized cost of $89,780,000 with a corresponding fair value of $89,757,000 from AFS to HTM. The net unrealized loss, net of taxes, on these securities at the date of the transfer was $15,000. The net unrealized holding loss at the time of transfer continues to be reported in AOCI, net of tax and is amortized over the remaining lives of the securities as an adjustment of the yield. The amortization of the net unrealized loss reported in AOCI will offset the effect on interest income of the discount for the transferred securities. The remaining unamortized balance of the net unrealized losses for the securities transferred from AFS to HTM was $38,000, net of taxes, at December 31, 2025. This compares to $47,000, net of taxes at December 31, 2024. These securities were transferred as a part of the Company's overall investment and balance sheet strategies.

The following table sets forth the Company's investment securities at their carrying amounts as of December 31, 2025 and 2024:

The Company adopted ASC 326, the CECL standard in 2023. In conjunction with adoption, holdings of AFS securities and HTM securities were evaluated to determine the need to establish an ACL, if any. The total ACL for HTM securities was $146,000 and $196,000 as of December 31, 2025 and 2024, respectively. Further details are included in Note 3 of the accompanying financial statements.

The following table sets forth information on the yields and expected maturities of the Company's investment securities as of December 31, 2025. Yields on tax-exempt securities have been computed on a tax-equivalent basis using a tax rate of 21%. Mortgage-backed securities are presented according to their contractual maturity date, while the yield takes into effect intermediate cash flows from repayment of principal which results in a much shorter average life.

AFS Debt Securities in an Unrealized Loss Position

The AFS securities portfolio contains certain securities, the amortized cost of which exceeds fair value, which at December 31, 2025 amounted to $40.1 million, or 13.19% of the amortized cost of the total AFS securities portfolio. At December 31, 2024, this amount was $54.2 million, or 16.48% of the total AFS securities portfolio.

The Company's evaluation of securities for impairment is a quantitative and qualitative process intended to determine whether declines in the fair value of AFS investment securities should be recognized as a charge against the ACL. The primary factors considered in evaluating whether a loss should be recognized include: (a) the length of time and extent to which the fair value has been less than cost or amortized cost and the expected recovery period of the security, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments, (d) the volatility of the securities market price, (e) the intent and ability of the Company to retain the investment for a

The First Bancorp - 2025 Form 10-K - Page 33

period of time sufficient to allow for recovery, which may be at maturity, and (f) any other information and observable data considered relevant in determining whether full collection of amounts contractually due will be realized.

The Company's best estimate of cash flows uses severe economic recession assumptions due to market uncertainty. The Company's assumptions include but are not limited to delinquencies, foreclosure levels and constant default rates on the underlying collateral, loss severity ratios, and constant prepayment rates. If the Company does not expect to receive 100% of future contractual principal and interest, a charge against the ACL is recognized. Estimating future cash flows is a quantitative and qualitative process that incorporates information received from third party sources along with certain internal assumptions and judgments regarding the future performance of the underlying collateral.

As of December 31, 2025, the Company had AFS debt securities in an unrealized loss position with a fair value of $228.7 million and unrealized losses of $40.1 million, as identified in the table below. Securities in a continuous unrealized loss position of twelve months or more amounted to a fair value $226.9 million as of December 31, 2025, compared with $234.1 million at December 31, 2024. The Company has concluded that these securities are fully collectible and that no charge against the allowance is required. This conclusion was based on the issuer's continued satisfaction of the securities obligations in accordance with their contractual terms and the expectation that the issuer will continue to do so, Management's intent and ability to hold these securities for a period of time sufficient to allow for any anticipated recovery in fair value which may be at maturity, the expectation that the Company will receive 100% of future contractual cash flows, as well as the evaluation of the fundamentals of the issuer's financial condition and other objective evidence. The following table summarizes AFS debt securities in an unrealized loss position for which an ACL has not been recorded at December 31, 2025:

For securities with unrealized losses, the following information was considered in determining that no charge against the allowance for decline in fair value was required in the current reporting period:

AFS Securities issued by the U.S. Treasury and U.S. Government-sponsored agencies & enterprises. As of December 31, 2025, the total unrealized losses on these securities amounted to $5.0 million, compared with $6.2 million at December 31, 2024. All of these securities were credit rated "AAA" or "AA+" by the major credit rating agencies. Management believes that securities issued by the U.S. Treasury and U.S. Government-sponsored agencies and enterprises carry zero or near-zero credit risk, and that 100% of the amounts contractually due will be collected.

AFS Mortgage-backed securities issued by U.S. Government agencies and U.S. Government-sponsored enterprises. As of December 31, 2025, the total unrealized losses on these securities amounted to $30.1 million, compared with $41.0 million at December 31, 2024. All of these securities were credit rated "AAA" by the major credit rating agencies. Management believes that securities issued by U.S. Government agencies bear no credit risk because they are backed by the full faith and credit of the United States and that securities issued by U.S. Government-sponsored enterprises have minimal credit risk, as these agencies enterprises play a vital role in the nation's financial markets. Management believes that the unrealized losses at December 31, 2025 were attributable to changes in current market yields and spreads since the date the underlying securities were purchased, and that 100% of the amounts contractually due will be realized. The Company also has the ability and intent to hold these securities until a recovery of their amortized cost, which may be at maturity.

AFS Obligations of state and political subdivisions. As of December 31, 2025, the total unrealized losses on municipal securities amounted to $5.0 million, compared with $6.9 million at December 31, 2024. Municipal securities are supported by the general taxing authority of the municipality and, in the cases of school districts, are generally supported by state aid. At December 31, 2025, all municipal bond issuers were current on contractually obligated interest and principal payments. The Company attributes the unrealized losses at December 31, 2025 to changes in prevailing market yields and pricing spreads since the date the underlying securities were purchased, combined with current market liquidity conditions and market conditions in general. The Company has the ability and intent to hold these securities until a recovery of their amortized cost, which may be at maturity, and believes that 100% of the amounts contractually due will be realized.

The First Bancorp - 2025 Form 10-K - Page 34

AFS Asset-backed securities. As of December 31, 2025, total unrealized losses on asset-backed securities were $15,000, compared with none at December 31, 2024. These securities consist of U.S Government backed student loans along with other credit enhancements.

FHLBB and FRBB Stock

The Bank is a member of the FHLBB, a cooperatively owned wholesale bank for housing and finance in the six New England States. As a requirement of membership in the FHLBB, the Bank must own a minimum required amount of FHLBB stock, calculated periodically based primarily on its level of borrowings from the FHLBB. The Bank uses the FHLBB for a portion of its wholesale funding needs. As of December 31, 2025 and 2024, the Bank's investment in FHLB stock totaled $7.2 million and $6.2 million, respectively. FHLBB stock is a non-marketable equity security and therefore is reported at cost, subject to adjustments for any observable market transactions on the same or similar instruments of the investee. No impairment losses have been recorded through December 31, 2025.

The Bank is also a member of the FRBB. As a requirement for membership in the FRBB, the Bank must own a minimum required amount of FRBB stock. The Bank uses FRBB for certain correspondent banking services and maintains borrowing capacity at its discount window. The Bank's investment in FRBB stock totaled $1.0 million at December 31, 2025 and 2024. The Company periodically evaluates its investment in FHLBB and FRBB stock for impairment based on, among other factors, the capital adequacy of the Banks and their overall financial condition. No impairment losses have been recorded through December 31, 2025. The Bank will continue to monitor its investment in these restricted equity securities.

Lending Activities

The Company provides loans to customers within our market area, the State of Maine, with very limited exposures outside of Maine. Loans are originated primarily via our network of branch offices, along with an online channel for residential mortgage loans.

The loan portfolio increased $53.2 million or 2.3% in 2025, with total loans of $2.394 billion at December 31, 2025, compared to $2.341 billion at December 31, 2024. Commercial loans increased $17.5 million or 1.3% between December 31, 2024 and December 31, 2025. Residential term loans increased by $28.4 million or 4.0%, home equity lines of credit increased $19.2 million or 15.6%, and municipal loans decreased by $9.8 million or 15.8% over the same period.

The loan portfolio is segmented into eleven classes. Commercial loans comprise six of the classes: commercial real estate owner occupied, commercial real estate non-owner occupied, commercial construction, C&I, multifamily and agriculture. Residential mortgage loans comprise two of the classes: residential real estate term and residential real estate construction. The remaining classes are municipal loans, home equity loans, and consumer loans. Further descriptions of each class, and the risk factors associated with each, are included in Note 5 and Note 6 of the accompanying financial statements.

The following table summarizes the loan portfolio, by class, as of December 31, 2025 and 2024:

Loan Concentrations

As of December 31, 2025, the Bank had one concentration of loans in one particular industry that exceeded 10% of its total loan portfolio: (1) loans to lessors of residential buildings and dwellings, totaling $266.1 million, or 11.11%. This compares to two concentrations of loans in two particular industries that exceeded 10% of its total loan portfolio as of December 31, 2024: (1) loans to lessors of residential buildings and dwellings, totaling $260.7 million, or 11.14%, of total loans, and (2) loans to hotels (except Casino hotels) and motels, totaling $242.1 million, or 10.34% of total loans.

Loans Held for Sale

As of December 31, 2025 and 2024, the Bank had no loans held for sale.

Credit Risk Management and Allowance for Credit Losses on Loans

Upon adoption of ASC 326, the CECL standard, in 2023, the Company replaced the incurred loss model that recognized loan losses when it became probable that a credit loss would be incurred, with a requirement to recognize lifetime expected credit losses immediately when a financial asset is originated or purchased. The ACL is a valuation amount that is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the allowance when they are deemed uncollectible. The ACL consists of three elements: (1) specific reserves for loans individually analyzed; (2) general reserves for each portfolio segment; and, (3) qualitative reserves. All outstanding loans are considered in evaluating the appropriateness of the allowance with similar risk characteristics in the portfolio. Prior to adoption of ASC 326, under the incurred loss methodology, the Company evaluated portfolio risk characteristics largely on loan purpose.

The Company provides for loan losses through the ACL which represents an estimated reserve for losses in the loan portfolio. To determine an appropriate level for general reserves, a discounted cash flow approach is applied to each portfolio segment implementing a probability of default and loss given default estimate based upon a number of factors including historical losses over an economic cycle, economic forecasts, loan prepayment speeds and curtailment rates. To determine an appropriate level for qualitative reserves various factors are considered including underwriting policies, credit administration practices, experience, ability and depth of lending management, and economic factors not captured in the general reserve calculation.

The ACL is increased by provisions charged against current earnings. Loan losses are charged against the allowance when Management believes that the collectibility of the loan principal is unlikely. Recoveries on loans previously charged off are credited to the allowance. The adequacy of the ACL is overseen by the ACL Committee whose membership includes senior level personnel from the Executive, Lending, Risk, and Finance functions of the Bank. While Management uses available information to assess possible losses on loans, future additions to the allowance may be necessary based on increases in non-performing loans, changes in economic conditions or outlook, growth in loan portfolios, or for other reasons. Any future additions to the allowance would be recognized in the period in which they were determined to be necessary. In addition, various regulatory agencies periodically review the Company's ACL as an integral part of their examination process. Such agencies may require the Company to record additions to the allowance based on judgments different from those of Management.

The ACL includes reserve amounts assigned to IAL. This includes loans with balances of $250,000 or more that have either been placed into non-accrual or are loans identified by management as having characteristics that may impact ultimate collectability and therefore merit individual analysis. A specific reserve is allocated to an individual loan when the amount of a probable loss is estimable on the basis of its collateral value, the present value of anticipated future cash flows, or its net realizable value. At December 31, 2025, IALs with specific reserves totaled $4.1 million and the amount of such reserves was $2.7 million. This compares to IALs with specific reserves of $1.7 million at December 31, 2024 and the amount of such reserves was $1.0 million. Additional detail on IALs may be found in Note 5 of the accompanying financial statements.

The total ACL on loans at December 31, 2025 is considered by Management to be appropriate to address the potential for credit losses inherent in the loan portfolio at that date. However, determination of the appropriate allowance level is based upon a number of assumptions made about future events, which we believe are reasonable, but which may or may not prove valid. Thus, there can be no assurance charge-offs in future periods will not exceed the ACL or that additional increases in the ACL will not be necessary.

The following table summarizes our allocation of allowance by loan class as of December 31, 2025 and 2024. The percentages are the portion of each loan type to total loans:

A breakdown of the ACL as of December 31, 2025, by loan class, and allowance element, is presented in the following table:

Based upon Management's evaluation, provisions are made to maintain the allowance as a best estimate of expected losses within the portfolio. The provision for credit losses to maintain the allowance was $2.0 million in 2025 compared to $1.3 million in 2024. Net charge offs were $1.6 million in 2025 compared to net charge offs of $463,000 in 2024. The ACL as a percentage of outstanding loans was at 1.06% at December 31, 2025 compared to 1.06% at December 31, 2024.

ACL for Unfunded Commitments

Adoption of CECL resulted in an increase in the Company's ACL for unfunded commitments. Our modeling methodology applies the same class level credit loss factors used in the ACL for loans model to applicable classes of unfunded commitments to determine an appropriate ACL level. Utilization assumptions are based upon an independent analysis of the Bank's historical data. The ACL for unfunded commitments is reported on the Company's consolidated balance sheets within other liabilities and totaled $565,000 as of December 31, 2025.

Nonperforming Loans

Nonperforming loans are comprised of loans, for which based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement or when principal and interest is 90 days or more past due unless the loan is both well secured and in the process of collection (in which case the loan may continue to accrue interest in spite of its past due status). A loan is "well secured" if it is secured (1) by collateral in the form of liens on or pledges of real or personal property, including securities, that have a realizable value sufficient to discharge the debt including accrued interest) in full, or (2) by the guarantee of a financially responsible party. A loan is "in the process of collection" if collection of the loan is proceeding in due course either (1) through legal action, including judgment enforcement procedures, or (2) in appropriate circumstances, through collection efforts not involving legal action which are reasonably expected to result in repayment of the debt or in its restoration to a current status in the near future.

Generally, when a loan becomes 90 days past due it is evaluated for collateral dependency based upon the most recent appraisal or other evaluation method. If the collateral value is lower than the outstanding loan balance plus accrued interest and estimated selling costs, the loan is placed on non-accrual status, all accrued interest is reversed from interest income, and a specific reserve is established for the difference between the loan balance and the collateral value less selling costs, or, in certain situations, the difference between the loan balance and the collateral value less selling costs is written off. Concurrently, a new appraisal or valuation may be ordered, depending on collateral type, currency of the most recent valuation, the size of the loan, and other factors appropriate to the loan. Upon receipt and acceptance of the new valuation, the loan may have an additional specific reserve or write down based on the updated collateral value. On an ongoing basis, appraisals or valuations may be done periodically on collateral dependent nonperforming loans and an additional specific reserve or write down will be made, if appropriate, based on the new collateral value.

Once a loan is placed on nonaccrual, it remains in nonaccrual status until the loan is current as to payment of both principal and interest and the borrower demonstrates the ability to pay and remain current. All payments made on nonaccrual loans are applied to the principal balance of the loan.

Nonperforming loans, expressed as a percentage of total loans, totaled 0.54% at December 31, 2025 compared to 0.18% at December 31, 2024. The following table shows the distribution of nonperforming loans by class as of December 31, 2025 and 2024:

The First Bancorp - 2025 Form 10-K - Page 40

The amounts shown for total nonperforming loans do not include loans 90 or more days past due and still accruing interest. These are loans in which we expect to collect all amounts due, including past-due interest. As of December 31, 2025, loans 90 or more days past due and still accruing interest totaled $665,000, compared to $1.0 million at December 31, 2024.

Loan Modifications Made to Borrowers Experiencing Financial Difficulty

The Company adopted ASU 2022-02 effective January 1, 2023. Reporting of loan modifications subject to ASU 2022-02 may be found in Note 5 of the accompanying financial statements.

Past Due Loans

The Bank's overall loan delinquency ratio was 0.90% at December 31, 2025, versus 0.40% at December 31, 2024. Loans 90 days delinquent and accruing decreased from $1.0 million at December 31, 2024 to $665,000 as of December 31, 2025.

The following table sets forth loan delinquencies as of December 31, 2025 and 2024:

Potential Problem Loans and Loans in Process of Foreclosure

Potential problem loans consist of classified, accruing commercial and commercial real estate loans that were between 30 and 89 days past due. Such loans are characterized by weaknesses in the financial condition of borrowers or collateral deficiencies. Based on historical experience, the credit quality of some of these loans may improve due to improvements in the economy as well as changes in collateral values or the financial condition of the borrowers, while the credit quality of other loans may deteriorate, resulting in some amount of loss. At December 31, 2025, there were five potential problem loans with a balance of $3.7 million or 0.156% of total loans. This compared to one potential problem loan with a balance of $84,000 or 0.004% of total loans at December 31, 2024.

As of December 31, 2025, there were seven residential loans in the process of foreclosure with a total balance of $1.8 million and one home equity line of credit totaling $63,000. The Bank's residential foreclosure process begins when a loan becomes 75 days past due at which time a Demand/Breach Letter is sent to the borrower. If the loan becomes 120 days past due, copies of the promissory note and mortgage deed are forwarded to the Bank's attorney for review and a complaint for foreclosure is then prepared. An authorized Bank officer signs the affidavit certifying the validity of the documents and verification of the past due amount which is then forwarded to the court. Once a Motion for Summary Judgment is granted, a POR begins which gives the customer 90 days to cure the default. A foreclosure auction date is then set 30 days from the POR expiration date if the default is not cured.

As of December 31, 2025, there were seven commercial loans in the process of foreclosure with a total balance of $3.8 million. The Bank's commercial foreclosure process begins when a loan becomes 60 days past due, at which time a default letter is issued. At expiration of the period to cure default, which lasts 12 days after the issuing of the default letter, copies of the

The First Bancorp - 2025 Form 10-K - Page 41

promissory note and mortgage deed are forwarded to the Bank's attorney for review. A Notice of Statutory Power of Sale is then prepared. This notice must be published for three consecutive weeks in a newspaper located in the county in which the property is located. A notice also must be issued to the mortgagor and all parties of interest 21 days prior to the sale. The foreclosure auction occurs and the Affidavit of Sale is recorded within the appropriate county within 30 days of the sale.

The Bank’s written policies and procedures for foreclosures, along with its implementation of said policies and procedures, are subject to annual review by its internal audit provider. The scope of this review includes loans held in portfolio and loans serviced for others. There were no issues requiring management attention in the most recent review. Servicing for others includes loans sold to FHLMC, FNMA, and the FHLBB through its MPF program. The Bank follows the published guidelines of each investor. Loans serviced for FHLMC and FNMA have been sold without recourse, and the Bank has no liability for these loans in the event of foreclosure. A de minimis volume of loans has been sold to and serviced for MPF to date. The Bank retains a second loss layer credit enhancement obligation; no losses have been recorded on this credit enhancement obligation since the Bank started selling loans to MPF in 2013.

Other Real Estate Owned

OREO and repossessed assets are comprised of properties or other assets acquired through a foreclosure proceeding, or acceptance of a deed or title in lieu of foreclosure. Real estate acquired through foreclosure is carried at the lower of cost or fair value less estimated cost to sell or the cost of the asset and is not included as part of the ACL totals. At December 31, 2025 there were no OREO properties and no allowance for losses. This compares to December 31, 2024 when there was one OREO property with a balance of $173,000, net of an allowance for OREO losses of $35,000. The table below presents the composition of OREO at December 31, 2025 and 2024:

Funding, Liquidity and Capital Resources

Liquidity

Liquidity is the ability of a financial institution to meet maturing liability obligations, depositor withdrawal requests, and customer loan demand. The Bank's lead source of liquidity is deposits, including brokered deposits, which funded 85.1% of total average assets in 2025, as compared to 85.6% a year ago. Other sources of funding include discretionary use of purchased liabilities (e.g., FHLBB term or overnight advances, and other borrowings), cash flows from the securities portfolio and loan repayments. Securities designated as AFS may also be sold in response to short-term or long-term liquidity needs, although

The First Bancorp - 2025 Form 10-K - Page 42

Management has no intention to do so at this time. While the generally preferred funding strategy is to attract and retain low cost deposits, our ability to do so is affected by competitive interest rates and terms in the marketplace.

The Bank has a detailed liquidity funding policy and a contingency funding plan that provide for prompt and comprehensive responses to unexpected demands for liquidity. Management has developed quantitative models to estimate needs for contingent funding that could result from unexpected outflows of funds in excess of "business as usual" cash flows. In Management's estimation, risks are concentrated amongst several major categories: runoff of in-market deposit balances, an inability to renew wholesale sources of funding, and materially increased utilization of available credit lines by borrowers. Of these, potential runoff of deposit balances would have the most significant impact on contingent liquidity. Our modeling attempts to quantify deposits at risk over selected time horizons. In addition to these outflow risks, several other "business as usual" factors enter into the calculation of the adequacy of contingent liquidity, including payment proceeds from loans and investment securities, maturing debt obligations and maturing time deposits. Stress testing analysis of liquidity resources under various scenarios is conducted no less than quarterly and results are reported to the ALCO. Borrowings supplement deposits as a source of liquidity; our borrowings typically consist of customer repurchase agreements and FHLBB advances. The Bank tests its borrowing capacity with the FRBB, the FHLBB and Fed Funds lines with other correspondents no less than annually; each has been successfully tested within the past year.

The Company defines its primary sources of contingent liquidity as cash & equivalents, unencumbered U.S. Government or Agency bond collateral, available capacity at FHLBB, and available authorized brokered deposit issuance capacity. As of December 31, 2025, the Bank had primary sources of contingent liquidity of $951.0 million or 30.3% of its total assets. It is Management's opinion that this is an appropriate level. In addition, the Bank has $313.0 million in borrowing capacity under the FRBB's Borrower in Custody programs as well as securities available as collateral, $101.0 million in credit lines with correspondent banks, and $40.0 million in other unencumbered securities available as collateral for borrowing. These bring the Bank's total sources of liquidity to $1.405 billion or 44.8% of its total assets.

The ALCO establishes guidelines for liquidity in its Asset/Liability policy and monitors internal liquidity measures to manage liquidity exposure. Based on its assessment of the liquidity considerations described above, Management believes the Company's sources of funding will meet anticipated funding needs.

The Company is dependent upon the payment of cash dividends by the Bank to service its commitments. As the sole shareholder of the Bank, the Company is entitled to such dividends when and as declared by the Bank's Board of Directors from legally available funds. For the years ended December 31, 2025, 2024 and 2023 the Bank declared dividends to the Company of $15.9 million, $15.8 million and $14.8 million, respectively. The Bank's regulator, the OCC, may limit the amount of dividends declared and paid in a calendar year based upon certain factors. Further discussion may be found in Capital Resources below.

Deposits

During 2025, total deposits decreased by $60.5 million, ending the year at $2.665 billion compared to $2.725 billion at December 31, 2024. Core deposit balances increased $77.0 million or 4.8%, focused in money market accounts. Certificates of Deposit decreased $137.5 million or 12.3% with the preponderance of the decrease being brokered time deposits.

Estimated uninsured deposits totaled $516.9 million, or 19.4% of total deposits, and $506.2 million, or 18.6% of total deposits, at December 31, 2025 and 2024, respectively. The company has pledged assets as collateral covering certain deposits; these amounts were $385.2 million and $349.8 million as of December 31, 2025 and 2024, respectively.

Average deposits increased $104.8 million in 2025, as shown in the following table, which sets forth the average daily balance for the Bank's principal deposit categories for each period:

The First Bancorp - 2025 Form 10-K - Page 43

The average cost of deposits (including non-interest-bearing accounts) was 2.82% for the year ended December 31, 2025, compared to 3.04% for the year ended December 31, 2024. The following table sets forth the average cost of each category of interest-bearing deposits for the periods indicated.

Of all certificates of deposit, $727.7 million or 74.46% will mature by December 31, 2026. As of December 31, 2025 and 2024, the Bank held a total of $147.7 million and $187.1 million in certificate of deposit accounts with balances in excess of $250,000, respectively. The following table summarizes the time remaining to maturity for these certificates of deposit.

Borrowed Funds

Borrowed funds consists of advances from the FHLBB, advances from the FRBB Discount Window, and securities repurchase agreements with customers. Advances from the FHLBB are secured with pledged collateral consisting of FHLBB stock, funds on deposit with FHLBB, U.S. Agency notes, mortgage-backed securities, and qualifying first mortgage loans. FRBB Discount Window advances are similarly secured with collateral consisting of FRBB stock, funds on deposit at FRBB, U.S. Agency notes or other eligible securities, and qualifying commercial, home equity and construction loans. As of December 31, 2025, term advances from FHLBB totaled $137.5 million, with a weighted average interest rate of 3.77% per annum. Overnight and short-term (maturing within thirty days) advances totaled $42 million, while longer term advances with remaining maturities ranging from one to five years totaled $95.5 million. This compares to term advances from FHLBB totaling $95.0 million, with an interest rate of 3.74% per annum as of December 31, 2024; there were no overnight advances. Of the $95.5 million in longer term advances outstanding as of December 31, 2025, advances totaling $95.0 million grant a put option to FHLBB to recall the advance at periodic intervals based upon interest rate movement and outlook.

The Bank offers securities repurchase agreements to municipal and corporate customers as an alternative to deposits. The balance of these agreements as of December 31, 2025 was $50.3 million, compared to $51.3 million on December 31, 2024. The weighted average interest rates payable under these agreements were 2.60% per annum as of December 31, 2025, compared to 2.87% per annum as of December 31, 2024.

The maximum amount of borrowed funds outstanding at any month-end during each of the last two years was $218.4 million at the end of February in 2025 and $230.6 million at the end of June in 2024. The average amount outstanding during 2025 was $178.1 million with a weighted average interest rate of 3.48% per annum. This compares to an average outstanding amount of $162.9 million with a weighted average interest rate of 3.38% per annum in 2024.

Capital Resources

Shareholders' equity as of December 31, 2025 was $283.1 million, compared to $252.5 million as of December 31, 2024.

During 2025, the Company declared cash dividends of $0.36 per share in the first quarter and $0.37 per share in the remaining three quarters, or $1.47 per share for the year. The dividend payout ratio, which is calculated by dividing dividends declared per share by basic earnings per share, was 47.39% for the year ended December 31, 2025 compared to 58.44% for the year ended December 31, 2024. In determining future dividend payout levels, the Board of Directors carefully analyzes capital requirements and earnings retention, as set forth in the Company's Dividend Policy. The ability of the Company to pay cash dividends to its shareholders depends on receipt of dividends from its subsidiary, the Bank. The subsidiary may pay dividends to its parent out of so much of its net profits as the Bank's directors deem appropriate, subject to the limitation that the total of all dividends declared by the Bank in any calendar year may not exceed the total of its net profits of that year combined with its

The First Bancorp - 2025 Form 10-K - Page 44

retained net profits of the preceding two years. The amount available for dividends in 2026 is this year's net income plus $31.8 million.

In 2025, 79,944 shares were issued via employee stock programs, the dividend reinvestment plan, and restricted stock grants. The Company received consideration totaling $916,000.  The following table summarizes the Company's 2025 stock issuances.

Financial institution regulators have established guidelines for minimum capital ratios for banks and bank holding companies. The net unrealized gain or loss on AFS securities is generally not included in computing regulatory capital. During the first quarter of 2015, the Company adopted the new Basel III regulatory capital framework as approved by the federal banking agencies. In order to avoid limitations on capital distributions, including dividend payments, the Company must hold a capital conservation buffer of 2.5% above the adequately capitalized risk-based capital ratios.

Capital at December 31, 2025 was sufficient to meet the requirements of regulatory authorities. Leverage capital of the Company, or total shareholders' equity divided by average total assets for the current quarter less goodwill and any net unrealized gain or loss on securities AFS and postretirement benefits, stood at 8.84% on December 31, 2025 and 8.47% at December 31, 2024. To be rated "well-capitalized", regulatory requirements call for a minimum leverage capital ratio of 5.00%. Given their capital structures, the regulatory Tier 1 capital and CET1 ratios are equal for both the Bank and the Company. At December 31, 2025, the Company had CET1 and tier-one risk-based capital ratios of 12.84%, and a tier-two, or total, risk-based capital ratio of 14.02%, versus 12.04% and 13.22%, respectively, at December 31, 2024. To be rated "well-capitalized", regulatory requirements call for minimum CET1, tier-one and tier-two risk-based capital ratios of 6.50%, 8.00% and 10.00%, respectively. The Company's actual levels of capitalization were comfortably above the standards to be rated "well-capitalized" by regulatory authorities.

The Company met each of the well-capitalized ratio guidelines at December 31, 2025. The following tables indicate the capital ratios for the Bank and the Company at December 31, 2025 and December 31, 2024.

Except as identified in Item 1A, "Risk Factors", Management knows of no present trends, events or uncertainties that will have, or are reasonably likely to have, a material effect on the Company's capital resources, liquidity, or results of operations.

Contractual Obligations

The following table sets forth the contractual obligations of the Company as of December 31, 2025:

Capital Purchases

In 2025, the Company made capital purchases totaling $3.2 million for facility improvements to branch or operations premises and technology investments in various hardware and software. This cost will be amortized over an average of seven years, adding approximately $200,000 to pre-tax operating costs per year.

Goodwill

On December 11, 2020, the Bank completed the purchase of a branch at 1B Belmont Avenue in Belfast, Maine, from Bangor Savings Bank ("Bangor Savings"). The branch is one of six branches Bangor Savings acquired from Damariscotta Bank & Trust Company ("DB&T"), and this branch was divested by Bangor Savings to resolve competitive concerns in that market raised by the U.S. Department of Justice's Antitrust Division. The transaction value was approximately $25.2 million consisting of loans, the building, equipment, core deposit intangible and goodwill. Goodwill totaled $841,000; this amount is not amortizable under GAAP but is amortizable for tax purposes.

On October 26, 2012, the Bank completed the purchase of a branch at 63 Union Street in Rockland, Maine, from Camden National Bank that was formerly operated by Bank of America. As part of the transaction, the Bank acquired approximately $32.3 million in deposits as well as a small volume of loans. The excess of the purchase price over the fair value of the assets acquired, liabilities assumed, and the amount allocated for core deposit intangible totaled $2.1 million and was recorded as goodwill. The goodwill is not amortizable under GAAP but is amortizable for tax purposes.

On January 14, 2005, the Company acquired FNB Bankshares (“FNB”) of Bar Harbor, Maine, and its subsidiary, The First National Bank of Bar Harbor. The total value of the transaction was $48.0 million, and all of the voting equity interest of FNB was acquired in the transaction. The transaction was accounted for as a purchase and the excess of purchase price over the fair value of net identifiable assets acquired equaled $27.6 million and was recorded as goodwill, none of which was deductible for tax purposes. The portion of the purchase price related to the core deposit intangible was amortized over its expected economic life.

Goodwill is evaluated annually for possible impairment under the provisions of FASB ASC Topic 350, “Intangibles – Goodwill and Other”. As of December 31, 2025, in accordance with Topic 350, the Company completed its annual review of goodwill and determined there has been no impairment. The Bank also carries $125,000 in goodwill for a de minimis transaction in 2001.

Effect of Future Interest Rates on Post-retirement Benefit Liabilities

In evaluating the Company's post-retirement benefit liabilities, Management believes changes in discount rates which have occurred pursuant to Federal legislation will not have a significant impact on the Company's future operating results or financial condition.

Climate Change

The Company is mindful of the potential risk of climate change on its operations as well as on its customers, vendors and other stakeholders. The Item 1A Risk Factors section of this 10-K highlights the general nature of climate change related risks. We expect these risks to increase over time, and expect that there may be a material financial impact, the extent of which cannot be reasonably estimated at this time. Increased regulation related to measurement and reporting of climate change risk may increase our operating costs, though we are unable to estimate the added cost at this time.

The Company and Bank strive to be responsible corporate citizens and have undertaken a number of initiatives in recent years to operate efficiently and reduce our carbon footprint. To reduce energy consumption we have installed energy efficient lighting in multiple locations, we have eliminated daily courier runs between branch locations, have installed high efficiency heating appliances in several locations, and when constructing a new branch location opted for a geothermal heating & cooling system. By leveraging technology platforms, we encourage customer use of digital banking products including electronic statement delivery, have reduced paper consumption by encouraging electronic data storage, and expanded the use of video conferencing technology saving employee travel requirements. Our lending activities include work with solar farm projects and

The First Bancorp - 2025 Form 10-K - Page 46

research laboratories working on climate change issues, we hold several green bonds in the investment portfolio, and our wealth management division works with clients who seek to direct their investments to be compatible with responsible ESG investing objectives. In management's opinion, none of these efforts has had a negative impact on the Company's operations.
