ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS Certain statements in this section and elsewhere in this Quarterly Report on Form 10-Q are forward-looking statements for purposes of the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. Such forward-looking statements may include financial and other projections as well as statements regarding the Corporation that may include future plans, objectives, performance, revenues, growth, profits, operating expenses or the Corporation’s underlying assumptions. Citizens & Northern Corporation and its wholly-owned subsidiaries (collectively, the “Corporation”) intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Reform Act of 1995. Forward-looking statements are not historical facts, are based on certain assumptions and describe future plans, business objectives and expectations, and are generally identifiable by the use of words such as, “may”, “would”, “will”, “should”, “likely”, “possibly”, “expect”, “anticipate”, “intend”, “pro forma”, “estimate”, “target”, “potentially”, “probably”, “outlook”, “predict”, “contemplate”, “continue”, “strategic”, “objective”, “plan”, “forecast”, “project”, “believe” and “goal” or other similar words, phrases or concepts. Persons reading this document are cautioned that such statements are only predictions, and that the Corporation’s actual future results or performance may be materially different. A number of factors could cause our actual results, events or developments, or industry results, to be materially different from any future results, events or developments expressed, implied or anticipated by such forward-looking statements. In addition to factors previously disclosed in the reports filed by the Corporation with the U.S. Securities and Exchange Commission, including our most recent annual report on Form 10-K and subsequent filings, and those identified elsewhere in this document, the following factors, among others, could cause actual results to differ materially from forward looking statements: ● changes in monetary and fiscal policies of the Federal Reserve Board and the U.S. Government, particularly related to changes in interest rates ● changes in general economic conditions, including unfavorable conditions and trends related to costs of living, unemployment levels, inflation, tariffs and economic growth ● military conflicts including the conflict in the Middle East and the possible expansion of such conflict and the potential geopolitical and economic consequences ● the potential for adverse developments in the banking industry that could have a negative impact on customer confidence ● the possibility that the Corporation’s credit standards and its on-going credit assessment processes might not protect it from significant credit losses ● difficulties in integrating the operations of the former Susquehanna (acquired by the Corporation October 1, 2025) ● legislative or regulatory changes ● downturn in demand for loan, deposit and other financial services in the Corporation’s market area ● increased competition from other banks and non-bank providers of financial services ● technological changes and increased technology-related costs ● information security breaches or other technology difficulties or failures ● changes in, or the application of, U.S GAAP with respect to the presentation of the Corporation’s financial statements ● fraud and cyber malfunction risks as usage of artificial intelligence continues to expand ● integration efforts between the Corporation and Susquehanna may divert the attention of the management teams of the Corporation and Susquehanna and cause a loss in the momentum of their ongoing businesses ● success of the Corporation in Susquehanna’s geographic market area will require the Corporation to attract and retain key personnel in the market and to differentiate the Corporation from its competitors in the market ​ These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. All forward-looking statements and information made herein are based on management’s current beliefs and assumptions as of the date of filing of this document. The Corporation does not undertake to update forward-looking statements. BUSINESS COMBINATION On October 1, 2025, the Corporation completed its acquisition of Susquehanna Community Financial, Inc. (“Susquehanna”). Susquehanna was the parent company of Susquehanna Community Bank, with seven banking offices located in Lycoming, Northumberland, Snyder and Union Counties in Pennsylvania. In connection with the acquisition, the Corporation issued approximately 2.3 million shares of common stock to the former Susquehanna shareholders, resulting in merger consideration valued at $44.6 million 32 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q and an increase in stockholders’ equity of $44.4 million, net of issuance costs. Intangible assets recorded included goodwill of $10.8 million and a core deposit intangible asset of $10.7 million. Assets acquired included loans valued at $393.6 million, securities valued at $147.6 million, bank-owned life insurance valued at $8.0 million and cash and due from banks of $6.1 million. Liabilities assumed included deposits valued at $501.5 million and short-term borrowings valued at $45.8 million. The assets purchased and liabilities assumed were recorded at their preliminary estimated fair values at the time of closing and may be adjusted for up to one year subsequent to the acquisition. There were no adjustments to the fair value measurements of assets acquired or liabilities assumed in the first six months of 2026. EARNINGS OVERVIEW Second Quarter 2026 as Compared to Second Quarter 2025 ​ Second quarter 2026 net income was $14,057,000, or $0.79 per diluted share, as compared to $6,117,000, or $0.40 per diluted share, in the second quarter 2025. Significant variances were as follows: ​ ● Net interest income of $29,618,000 in the second quarter 2026 was $8,476,000 higher than in the second quarter 2025, including the benefit of income from growth in net earning assets resulting from the Susquehanna merger. The net interest margin increased to 4.07% in the second quarter 2026 from 3.52% in the second quarter 2025. The interest rate spread increased 0.71%, as the average yield on earning assets increased 0.31% while the average rate on interest-bearing liabilities decreased 0.40%. Average total earning assets increased $508,544,000 from the second quarter 2025, as average total loans receivable increased $480,770,000, including the impact of loans acquired from Susquehanna, and average available-for-sale debt securities increased $79,739,000 while average interest-bearing due from banks decreased $53,262,000. Average total deposits increased $487,729,000, including the impact of deposits assumed from Susquehanna, while average brokered deposits decreased $8,450,000. ● The credit for credit losses was $1,846,000 in the second quarter 2026 as compared to a provision of $2,354,000 in the second quarter 2025. The credit for credit losses in the second quarter 2026 included the impact on the allowance for credit losses (“ACL”) of changes in qualitative factors, net recoveries of $403,000 and a reduction in loans receivable. The provision in the second quarter 2025 resulted mainly from increases in the ACL related to changes in qualitative factors and an economic forecast. In the second quarter 2026, net recoveries totaled $403,000 or 0.07% (annualized) of average loans receivable compared to net charge-offs of $548,000 or 0.12% (annualized) of average loans receivable in the second quarter 2025. During the second quarter 2026, there was a $675,000 recovery on a loan classified as nonaccrual that was paid off by a borrower through third-party financing. The ACL was 1.39% of gross loans receivable at June 30, 2026, down from 1.42% at March 31, 2026 and up from 1.32% at December 31, 2025 and 1.13% at June 30, 2025. ● Noninterest income of $9,800,000 in the second quarter 2026 increased $1,658,000 from the second quarter 2025 result. Significant variances included the following: Ø Service charges on deposit accounts of $1,761,000 increased $339,000, reflecting an increase in volume of fees. Ø Net gains from sale of loans of $608,000 increased $296,000, reflecting an increase in volume of residential mortgage loans sold and includes the impact of $207,000 in net gains from sale of loans primarily attributable to Susquehanna region lending personnel. Ø Other noninterest income of $2,305,000 increased $275,000, including an increase of $123,000 in dividends on Federal Home Loan Bank of Pittsburgh stock. Ø Trust revenue of $2,242,000 increased $275,000, consistent with appreciation in the trading prices of many U.S. equity securities and an increase in new business. 33 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q Ø Brokerage and insurance revenue of $816,000 increased $262,000, reflecting an increase in volume of new transactions. ​ Ø Interchange revenue from debit card transactions of $1,347,000 increased $129,000, including an increase in volume-related incentive income. ​ ● Noninterest expense of $23,839,000 in the second quarter 2026 increased $4,441,000 from the second quarter 2025 result, reflecting the impact of the Susquehanna acquisition. Significant variances included the following: Ø Salaries and employee benefits expense of $13,197,000 increased $2,130,000, including the impact of the Susquehanna acquisition, while cash and stock-based incentive compensation decreased $225,000. Ø Other noninterest expense of $4,799,000 increased $1,398,000 from the second quarter 2025 total. Within this category, significant variances included the following: ◾ Core deposit intangible amortization expense increased $708,000, related to core deposits assumed from Susquehanna. ◾ FDIC insurance expense increased $260,000 from the second quarter of 2026, reflecting the impact of the Susquehanna acquisition. ◾ Collection expense, net increased $103,000 to $98,000 for the second quarter 2026 from a credit of $5,000 for the second quarter 2025. Ø Net occupancy and equipment expense of $1,728,000 was $325,000 higher than in the second quarter 2025, including the impact of the Susquehanna acquisition and increases in snow removal/lawn care, light and power and repairs and maintenance expenses. Ø Data processing and telecommunications expenses of $2,249,000 were $268,000 higher than in the second quarter 2025, reflecting higher software license expense of $189,000 and higher internet banking expenses of $66,000, primarily related to the Susquehanna acquisition. ● The income tax provision of $3,368,000, or 19.3% of pre-tax income, for the second quarter 2026 increased $1,953,000 from $1,415,000, or 18.8% of pre-tax income, for the second quarter 2025 reflecting an increase in pre-tax income. ​ Six Months Ended June 30, 2026 as Compared to Six Months Ended June 30, 2025 Net income for the six-month period ended June 30, 2026 was $14,330,000, or $0.81 per diluted share, as compared to $12,410,000, or $0.80 per diluted share, for the first six months of 2025. Significant variances were as follows: ​ ● Net interest income of $58,072,000 in the first six months of 2026 was $16,955,000 higher than in the first six months of 2025, including the benefit of income from growth in net earning assets resulting from the Susquehanna merger. The consolidated net interest margin increased to 4.02% for the six months ended June 30, 2026 from 3.45% for the six months ended June 30, 2025. The interest rate spread increased 0.73%, as the average yield on earning assets increased 0.31% while the average rate on interest-bearing liabilities decreased 0.42%. Average total earning assets increased $507,185,000 as average total loans receivable increased $473,193,000, including the impact of loans acquired from Susquehanna, and average available-for-sale debt securities increased $80,636,000 while average interest-bearing due from banks decreased $47,851,000. Average total deposits increased $493,355,000, including the impact of deposits assumed from Susquehanna, while average brokered deposits decreased $16,347,000. ​ ● For the six months ended June 30, 2026, the provision for credit losses was $11,756,000 as compared to $2,590,000 in 2025. The increase in provision in the six months ended June 30, 2026 was driven by the impact on the ACL of an 34 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q elevated level of net charge-offs and was partially offset by decreases in the ACL related to changes in qualitative factors. Net charge-offs totaled $10,405,000, or 0.88% (annualized) of average loans receivable in the six months ended June 30, 2026 compared to $639,000 or 0.07% (annualized) of average loans receivable in the six months ended June 30, 2025. The significant increase in charge-offs in the six months ended June 30, 2026 was due to a non-owner occupied, commercial real estate loan originated in 2022 in the amount of $24 million of which $7,200,000 was participated with another financial institution. The loss of a large tenant as well as cash flow requirements of the borrower’s other properties (which the Corporation has not financed) caused the loan to be downgraded to substandard and placed on nonaccrual status as of June 30, 2026 and March 31, 2026. The Corporation obtained an updated appraisal in April 2026 which was significantly lower than the original appraisal when the loan was originated, resulting in a charge-off of $10,056,000 which was recorded in the first quarter 2026. In the second quarter 2026, the Corporation entered into a forbearance agreement with the borrower. During the second quarter 2026, the borrower made payments consistent with the terms of the forbearance agreement, including payments the Corporation recorded as reductions in the amortized cost basis of the loan totaling $171,000. At June 30, 2026, the amortized cost basis of the loan, net of the partial charge-off, is $5,665,000. ​ ● Noninterest income totaled $17,995,000 in the first six months of 2026, up $2,845,000 from the total for the first six months of 2025. The inclusion of Susquehanna in 2026 contributed significantly to volume-related increases in several categories of noninterest income. Significant variances included the following: ​ Ø Other noninterest income of $3,891,000 increased $729,000, including a conversion assistance payment of $241,000 related to the integration of former Susquehanna brokerage accounts to the Corporation’s wealth management platform, an increase of $201,000 in dividends on Federal Home Loan Bank of Pittsburgh stock and an increase of $82,000 in credit card interchange fees. ​ Ø Service charges on deposit accounts of $3,411,000 increased $549,000, reflecting an increase in volume of fees. ​ Ø Net gains from sale of loans of $978,000 increased $461,000, reflecting an increase in volume of residential mortgage loans sold and includes the impact of $340,000 in net gains from sale of loans primarily attributable to Susquehanna region lending personnel. Ø Interchange revenue from debit card transactions of $2,614,000 increased $360,000, including an increase in volume-related incentive income. Ø Brokerage and insurance revenues of $1,404,000 increased $352,000, reflecting an increase in volume of new transactions. Ø Trust revenue of $4,327,000 increased $258,000, consistent with appreciation in the trading prices of many U.S. equity securities and an increase in new business. ​ ● Noninterest expense totaled $46,551,000 for the first six months of 2026, an increase of $8,110,000 from the total for the first six months of 2025. The inclusion of Susquehanna in 2026 contributed to volume-related increases in several categories of noninterest expense. Significant variances included the following: ​ Ø Salaries and employee benefits expense of $26,398,000 increased $3,572,000, including the impact of the Susquehanna acquisition. Health insurance costs increased $608,000, or 32%, due to an increase in claims on the partially self-insured plan while cash and stock-based incentive compensation decreased $503,000. ​ Ø Other noninterest expense of $8,163,000 increased $2,408,000. Within this category, significant variances included the following: ◾ Core deposit intangible amortization expense increased $1,417,000, including $1,431,000 related to core deposits assumed from Susquehanna. 35 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q ◾ FDIC insurance expense increased $503,000 from 2025, reflecting the impact of the Susquehanna acquisition. Ø Net occupancy and equipment expense was $757,000 higher than in 2025, including $412,000 related to the Susquehanna acquisition and increases in snow removal/lawn care, light and power and repairs and maintenance. ​ Ø Data processing expense was $646,000 higher than in 2025 reflecting higher software license expense of $368,000 and higher internet banking expenses of $236,000, mainly due to the Susquehanna acquisition. ​ Ø Professional fees increased $360,000, including an increase in employment search firm fees. ​ Ø ATM and interchange expenses increased $328,000, reflecting the impact of the Susquehanna acquisition. ● The income tax provision of $3,430,000, or 19.3% of pre-tax income, for 2026 increased $604,000 from $2,826,000, or 18.5% of pre-tax income, for 2025 reflecting an increase in pre-tax income for 2026 . ​ ​ TABLE I – QUARTERLY FINANCIAL DATA ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars In Thousands, ​ For the Three Months Ended : Except Per Share Data) ​ June 30, ​ March 31, ​ December 31, ​ September 30, ​ June 30, (Unaudited) ​ ​ ​ 2026 ​ 2026 ​ 2025 ​ ​ ​ 2025 ​ 2025 Interest and dividend income ​ $ 41,566 ​ $ 40,588 ​ $ 41,404 ​ $ 33,650 ​ $ 32,454 Interest expense ​ 11,948 ​ 12,134 ​ 12,931 ​ 11,387 ​ 11,312 Net interest income ​ 29,618 ​ 28,454 ​ 28,473 ​ 22,263 ​ 21,142 (Credit) provision for credit losses ​ (1,846) ​ 13,602 ​ 1,320 ​ 2,163 ​ 2,354 Net interest income after (credit) provision for credit losses ​ 31,464 ​ 14,852 ​ 27,153 ​ 20,100 ​ 18,788 Noninterest income ​ 9,800 ​ 8,195 ​ 8,398 ​ 7,304 ​ 8,142 Merger-related expenses ​ ​ 0 ​ ​ 0 ​ ​ 6,891 ​ ​ 882 ​ ​ 167 Other noninterest expenses ​ 23,839 ​ 22,712 ​ 23,268 ​ 18,507 ​ 19,231 Income before income tax provision ​ 17,425 ​ 335 ​ 5,392 ​ 8,015 ​ 7,532 Income tax provision ​ 3,368 ​ 62 ​ 926 ​ 1,464 ​ 1,415 Net income ​ $ 14,057 ​ $ 273 ​ $ 4,466 ​ $ 6,551 ​ $ 6,117 Net income attributable to common shares ​ $ 14,057 ​ $ 273 ​ $ 4,437 ​ $ 6,498 ​ $ 6,068 Basic and diluted earnings per common share ​ $ 0.79 ​ $ 0.02 ​ $ 0.25 ​ $ 0.42 ​ $ 0.40 ​ ​ 36 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q NONINTEREST INCOME TABLE II – COMPARISON OF NONINTEREST INCOME ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in Thousands) ​ Three Months Ended ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ ​ $ ​ % ​ ​ ​ ​ ​ 2026 ​ 2025 ​ ​ ​ ​ Change ​ Change ​ ​ ​ Trust revenue ​ $ 2,242 ​ $ 1,967 ​ $ 275 ​ 14.0 % ​ Brokerage and insurance revenue ​ 816 ​ ​ 554 ​ ​ 262 ​ 47.3 % ​ Service charges on deposit accounts ​ 1,761 ​ ​ 1,422 ​ ​ 339 ​ 23.8 % ​ Interchange revenue from debit card transactions ​ 1,347 ​ ​ 1,218 ​ ​ 129 ​ 10.6 % ​ Net gains from sales of loans ​ 608 ​ ​ 312 ​ ​ 296 ​ 94.9 % ​ Loan servicing fees, net ​ 193 ​ ​ 173 ​ ​ 20 ​ 11.6 % ​ Increase in cash surrender value of life insurance ​ 527 ​ ​ 466 ​ ​ 61 ​ 13.1 % ​ Other noninterest income ​ 2,305 ​ ​ 2,030 ​ ​ 275 ​ 13.5 % ​ Realized gains on available-for-sale debt securities, net ​ ​ 1 ​ ​ 0 ​ ​ 1 ​ N/M ​ ​ Total noninterest income ​ $ 9,800 ​ $ 8,142 ​ $ 1,658 ​ 20.4 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in Thousands) ​ Six Months Ended ​ ​ ​ ​ ​ ​ ​ June 30, ​ ​ $ ​ % ​ ​ ​ ​ 2026 ​ 2025 ​ ​ ​ ​ Change ​ Change Trust revenue ​ $ 4,327 ​ $ 4,069 ​ $ 258 ​ 6.3 % Brokerage and insurance revenue ​ 1,404 ​ ​ 1,052 ​ ​ 352 ​ 33.5 % Service charges on deposit accounts ​ 3,411 ​ ​ 2,862 ​ ​ 549 ​ 19.2 % Interchange revenue from debit card transactions ​ 2,614 ​ ​ 2,254 ​ ​ 360 ​ 16.0 % Net gains from sales of loans ​ 978 ​ ​ 517 ​ ​ 461 ​ 89.2 % Loan servicing fees, net ​ 301 ​ ​ 311 ​ ​ (10) ​ (3.2) % Increase in cash surrender value of life insurance ​ 1,042 ​ ​ 923 ​ ​ 119 ​ 12.9 % Other noninterest income ​ 3,891 ​ ​ 3,162 ​ ​ 729 ​ 23.1 % Realized gains on available-for-sale debt securities, net ​ ​ 27 ​ ​ 0 ​ ​ 27 ​ N/M ​ Total noninterest income ​ $ 17,995 ​ $ 15,150 ​ $ 2,845 ​ 18.8 % ​ N/M Not Meaningful ​ NONINTEREST EXPENSE ​ TABLE III -

CRITICAL ACCOUNTING POLICIES The presentation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect many of the reported amounts and disclosures. Actual results could differ from these estimates. Business Combinations – The Corporation accounts for its mergers and acquisitions using the acquisition method of accounting under the provisions of FASB ASC Topic 805 ("ASC 805"), Business Combinations. Under ASC 805, the assets acquired, including identified intangible assets such as core deposit intangibles and liabilities assumed in a business combination are recognized at their acquisition-date fair value, while transaction costs and restructuring costs associated with the business combination are expensed as incurred. The excess of the merger consideration over the fair value of assets acquired and liabilities assumed, if any, is allocated to goodwill. ​ The valuations are based upon management’s assumptions of future growth rates, future attrition, discount rates and other relevant factors, which involves a significant level of estimation and uncertainty. In addition, management engaged independent third-party specialists to assist in the development of the fair values of the acquired assets and assumed liabilities. The preliminary estimates of fair values may be adjusted for a period of time subsequent to the acquisition date if new information is obtained about facts and circumstances that existed as of the merger date that, if known, would have affected the measurement of the amounts recognized as of that date. Adjustments would be recorded to goodwill during the current reporting period. ​ Examples of the impacted acquired assets and assumed liabilities include loans, deposits, identifiable intangible assets and certain other assets and liabilities. For acquired loans at the merger date, management evaluated and classified loans based upon whether the loans had experienced a more-than-insignificant amount of credit deterioration since origination. To determine the fair value of the loans, significant estimates and assumptions were applied, including projected cash flows, discount rates, repayment speeds, credit loss severity rates, default rates and realizable collateral values. In November 2025, the Financial Accounting Standards Board issued Accounting Standards Update 2025-08, Financial Instruments – Credit Losses (“ASU 2025-08”). The Corporation adopted ASU 2025-08 in accounting for the Susquehanna acquisition. Consistent with ASU 2025-08, the Corporation recorded loans receivable at fair value plus an allowance for credit losses of $7.1 million, including allowances totaling $2.6 million on loans with more than insignificant deterioration in credit quality subsequent to origination (“PCD”) loans and an allowance of $4.5 million on non-PCD loans at acquisition. Allowance for Credit Losses on Loans – A material estimate that is particularly susceptible to significant change is the determination of the allowance for credit losses (ACL) on loans. The Corporation maintains an ACL on loans which represents management’s estimate of expected net charge-offs over the life of the loans. The ACL includes two primary components: (i) an allowance established on loans which share similar risk characteristics collectively evaluated for credit losses (collective basis), and (ii) an allowance established on loans which do not share similar risk characteristics with any loan segment and which are individually evaluated for credit losses (individual basis). Management considers the determination of the ACL on loans to be critical because it requires significant judgment 38 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q regarding estimates of expected credit losses based on the Corporation’s historical loss experience, current conditions and economic forecasts. Management’s evaluation is based upon a continuous review of the Corporation’s loans, with consideration given to evaluations resulting from examinations performed by regulatory authorities. Note 7 to the unaudited consolidated financial statements provides an overview of the process management uses for determining the ACL, and additional discussion of the ACL is provided in a separate section below of Management’s Discussion and Analysis. The ACL may increase or decrease due to changes in economic conditions affecting borrowers and macroeconomic variables, including new information regarding existing problem loans, identification of additional problem loans, changes in the fair value of underlying collateral, unforeseen events such as natural disasters and pandemics, and other factors. Because current economic conditions and forecasts can change and future events are inherently difficult to predict, the anticipated amount of estimated credit losses on loans, and therefore the appropriateness of the ACL, could change significantly. The allowance for credit losses is adjusted by qualitative factors to capture current economic conditions and risk characteristics not fully reflected in historical data. During the three months ended June 30, 2026, the Corporation refined its estimation methodology for calculating some of the qualitative factors, including changes in the application of external data used to assess trends in regional economic conditions, commercial real estate values and residential real estate values. Management believes these refinements in methodology result in an improved estimate of the impact on the ACL of recent trends in the external data. NET INTEREST INCOME The Corporation’s primary source of operating income is net interest income, which is equal to the difference between the amounts of interest income and interest expense. Tables IV, V and VI include information regarding the Corporation’s net interest income for the three-month and six-month periods ended June 30, 2026 and 2025. In each of these tables, the amounts of interest income earned on tax-exempt securities and loans have been adjusted to a fully taxable-equivalent basis. Management believes presentation of net interest income on a fully taxable-equivalent basis, which is a non-U.S. GAAP financial measure, provides investors with meaningful information for purposes of comparing returns on tax-exempt securities and loans with returns on taxable securities and loans. Accordingly, the amount of net interest income on a fully taxable-equivalent basis reflected in these tables exceed the net interest income amounts presented in the consolidated financial statements. A reconciliation of net interest income on a fully taxable-equivalent basis to the closest U.S. GAAP financial measure is included with Table IV. The discussion that follows is based on amounts in the related tables.

(2) The change in interest due to both volume and rates has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amount of the change in each. INCOME TAXES The income tax provision in interim periods is based on the Corporation’s estimate of the effective tax rate expected to be applicable for the full year. The income tax provision for the second quarter 2026 of $3,368,000 was $1,953,000 higher than the provision for the second quarter 2025, and the provision for the six months ended June 30, 2026 of $3,430,000 was $604,000 higher than the amount for the first six months of 2025 due to a higher amount of pre-tax income in 2026. The effective tax rate (tax provision as a percentage of pre-tax income) was 19.3% in the second quarter 2026 compared to 18.8% in the second quarter 2025 and 19.3% for the first six months of 2026 as compared to 18.5% for the first six months of 2025. The Corporation’s effective tax rates differ from the statutory federal rate of 21% principally because of the effects of tax-exempt interest income, nondeductible interest expense, state income taxes and other permanent differences. 44 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q The Corporation recognizes deferred tax assets and liabilities based on differences between the consolidated financial statement carrying amounts and the tax basis of assets and liabilities. The net deferred tax asset at June 30, 2026 and December 31, 2025 represents the following temporary difference components: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, ​ ​ ​ December 31, (In Thousands) ​ 2026 ​ 2025 Deferred tax assets: ​ ​ ​ ​ Unrealized holding losses on available-for-sale debt securities ​ $ 6,848 ​ $ 6,531 Allowance for credit losses on loans ​ ​ 7,098 ​ ​ 6,765 Acquisition accounting adjustment on loans ​ 1,450 ​ 1,727 Deferred compensation ​ ​ 2,090 ​ ​ 2,008 Deferred loan origination fees ​ 722 ​ 712 Operating leases liability ​ 748 ​ 780 Net operating loss carryforward ​ ​ 263 ​ ​ 305 Accrued incentive compensation ​ ​ 290 ​ ​ 735 Bank premises and equipment ​ ​ 100 ​ ​ 56 Other deferred tax assets ​ 2,242 ​ 1,708 Total deferred tax assets ​ 21,851 ​ 21,327 ​ ​ ​ ​ ​ Deferred tax liabilities: ​ ​ ​ ​ Core deposit intangibles ​ 2,166 ​ 2,522 Right-of-use assets from operating leases ​ 722 ​ 780 Mortgage servicing rights ​ ​ 178 ​ ​ 210 Defined benefit plans - ASC 835 ​ 88 ​ 97 Other deferred tax liabilities ​ 80 ​ 103 Total deferred tax liabilities ​ 3,234 ​ 3,712 Deferred tax asset, net ​ $ 18,617 ​ $ 17,615 ​ The Corporation regularly reviews deferred tax assets for recoverability based on history of earnings, expectations for future earnings and expected timing of reversals of temporary differences. Realization of deferred tax assets ultimately depends on the existence of sufficient taxable income. Management believes the recorded net deferred tax asset at June 30, 2026 is fully realizable; however, if management determines the Corporation will be unable to realize all or part of the net deferred tax asset, the Corporation would adjust the deferred tax asset, which would negatively impact earnings . SECURITIES Management continually evaluates several objectives in determining the size, securities mix and other characteristics of the available-for-sale debt securities (investment) portfolio. Key objectives include supporting liquidity needs and maximizing return on earning assets within reasonable risk parameters. 45 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q The composition of the available-for-sale debt securities portfolio at June 30, 2026 and December 31, 2025, 2024 and 2023 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars In Thousands) ​ June 30, 2026 ​ December 31, 2025 December 31, 2024 ​ December 31, 2023 ​ ​ ​ Amortized ​ Fair ​ Amortized ​ Fair Amortized ​ Fair ​ Amortized ​ Fair ​ ​ Cost Value Cost Value ​ Cost Value ​ Cost Value ​ Obligations of the U.S. Treasury ​ $ 8,036 ​ ​ 7,433 ​ $ 8,047 ​ ​ 7,482 ​ $ 8,067 ​ ​ 7,118 ​ $ 12,325 ​ ​ 11,290 ​ Obligations of U.S. Government agencies ​ ​ 10,776 ​ ​ 10,017 ​ ​ 11,423 ​ ​ 10,749 ​ ​ 10,154 ​ ​ 9,025 ​ ​ 11,119 ​ ​ 9,946 ​ Bank holding company debt securities ​ ​ 40,097 ​ ​ 38,857 ​ ​ 36,103 ​ ​ 34,076 ​ ​ 28,958 ​ ​ 25,246 ​ ​ 28,952 ​ ​ 23,500 ​ Obligations of states and political subdivisions: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tax-exempt ​ 102,543 ​ ​ 95,961 ​ 105,149 ​ ​ 98,359 ​ 111,995 ​ ​ 101,302 ​ 113,464 ​ ​ 104,199 ​ Taxable ​ 50,172 ​ ​ 43,854 ​ 50,306 ​ ​ 44,152 ​ 51,147 ​ ​ 42,506 ​ 58,720 ​ ​ 50,111 ​ Mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored agencies: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Residential pass-through securities ​ 150,796 ​ ​ 144,681 ​ 148,865 ​ ​ 143,921 ​ 104,378 ​ ​ 94,414 ​ 105,549 ​ ​ 95,405 ​ Residential collateralized mortgage obligations ​ 59,098 ​ ​ 56,477 ​ 65,782 ​ ​ 63,707 ​ 53,389 ​ ​ 49,894 ​ 50,212 ​ ​ 46,462 ​ Commercial mortgage-backed securities ​ 98,443 ​ ​ 91,539 ​ 99,095 ​ ​ 92,631 ​ 73,470 ​ ​ 64,501 ​ 76,412 ​ ​ 66,682 ​ Private label commercial mortgage-backed securities ​ ​ 0 ​ ​ 0 ​ ​ 3,490 ​ ​ 3,489 ​ ​ 8,365 ​ ​ 8,374 ​ ​ 8,215 ​ ​ 8,160 ​ Asset-backed securities, ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Collateralized loan obligations ​ ​ 8,000 ​ ​ 8,010 ​ ​ 8,000 ​ ​ 8,009 ​ ​ 0 ​ ​ 0 ​ ​ 0 ​ ​ 0 ​ Total Available-for-Sale Debt Securities ​ $ 527,961 ​ $ 496,829 ​ $ 536,260 ​ $ 506,575 ​ $ 449,923 ​ $ 402,380 ​ $ 464,968 ​ $ 415,755 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net Unrealized Loss ​ ​ ​ ​ $ (31,132) ​ ​ ​ ​ $ (29,685) ​ ​ ​ ​ $ (47,543) ​ ​ ​ ​ $ (49,213) ​ Net Unrealized Loss as a % of Amortized Cost ​ ​ ​ ​ ​ (5.9) % ​ ​ ​ ​ (5.5) % ​ ​ ​ ​ (10.6) % ​ ​ ​ ​ (10.6) % ​ As reflected in the table above, the fair value of available-for-sale securities was lower than the amortized cost basis by $31,132,000, or 5.9%, at June 30, 2026, $29,685,000, or 5.5%, at December 31, 2025, $47,543,000, or 10.6%, at December 31, 2024 and $49,213,000, or 10.6%, at December 31, 2023. The volatility in the fair value of the portfolio, including the significant reduction in fair value, resulted from changes in interest rates. Additional information regarding the potential impact of interest rate changes on all of the Corporation’s financial instruments is provided in Item 3, Quantitative and Qualitative Disclosures about Market Risk. As described in Note 6 to the unaudited consolidated financial statements, management determined the Corporation does not have the intent to sell, nor is it more likely than not that it will be required to sell, available-for-sale debt securities in an unrealized loss position at June 30, 2026 before it is able to recover the amortized cost basis. Further, management reviewed the Corporation’s holdings as of June 30, 2026 and concluded there were no credit-related declines in fair value. Additional information related to the types of securities held at June 30, 2026, other than securities issued or guaranteed by U.S. Government entities or agencies, was as follows: ● Bank holding company debt securities – The Corporation’s holdings of bank holding company debt securities included one senior and fourteen subordinated securities with face amounts ranging from $250,000 to $5 million. There have been no payment defaults on the securities . All of the obligors have publicly traded common stock. At June 30, 2026, one of the securities with a face amount of $400,000 is unrated, and the rest of securities have external ratings ranging from BBB-/Baa3 to A-. 46 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q ● Obligations of states and political subdivisions (municipal bonds) – All of the Corporation’s holdings of municipal bonds were investment grade and there have been no payment defaults. Summary ratings information at June 30, 2026, based on the amortized cost basis and reflecting the lowest enhanced or underlying rating by Moody’s, Standard & Poors or Fitch, is as follows: AAA or pre-refunded – 20% of the portfolio; AA – 72%; A – 8%. ● Collateralized loan obligations (CLOs) – There were three CLOs securities, all of which were from the most senior payment (subordination) classes of their respective issuances. These securities were investment grade (rated Aaa), and there have been no payment defaults on these securities. Based on the results of management’s assessment, there was no ACL required on available-for-sale debt securities in an unrealized loss position at June 30, 2026. FINANCIAL CONDITION This section includes information regarding the Corporation’s lending activities or other significant changes or exposures that are not otherwise addressed in Management’s Discussion and Analysis. Significant changes in the average balances of the Corporation’s earning assets and interest-bearing liabilities are described in the Net Interest Income section of Management’s Discussion and Analysis. Other significant balance sheet items, including securities, the allowance for credit losses and stockholders’ equity, are discussed in separate sections of Management’s Discussion and Analysis. There are no significant concerns that have arisen related to the Corporation’s off-balance sheet loan commitments or outstanding letters of credit at June 30, 2026. Table VII shows the composition of the loan portfolio at June 30, 2026 and at year-end from 2021 through 2025. Throughout this time period, the portfolio was primarily commercial in nature. At June 30, 2026, commercial loans represented 76% of the portfolio while residential loans totaled 19% of the portfolio. As shown in Table VII, total loans receivable were higher by $458,517,000 at December 31, 2025 as compared to December 31, 2024. On October 1, 2025, $ 393,587,000 of gross loans receivable, net of purchase accounting adjustments, were recorded pursuant to the acquisition of Susquehanna. Also included in Table VII is additional detail as of June 30, 2026 and December 31, 2025 regarding the composition of the non-owner occupied commercial real estate loan portfolio. As shown in Table VII, at June 30, 2026, the amortized cost of non-owner occupied commercial real estate loans for which the primary purpose is utilization of office space by third parties was $107,923,000, or 4.6% of gross loans receivable. At June 30, 2026, within this segment there were two loans with a total amortized cost basis of $6,832,000 in nonaccrual status with no individual allowances, including the loan discussed in the Earnings Overview and Provision and Allowance for Credit Losses section with a partial charge-off of $10,056,000 in the first quarter 2026 and an amortized cost basis at June 30, 2026 of $5,665,000. During the second quarter of 2026, a nonaccrual loan within this category o f $1,717,000 was paid off by the borrower through third-party financing and a $675,000 recovery was recorded . The remainder of the non-owner occupied commercial real estate loans with a primary purpose of office space utilization were in accrual status with no individual allowance at June 30, 2026. While the Corporation’s lending activities are primarily concentrated in its market areas, a portion of the Corporation’s commercial loan segment consists of participation loans. Participation loans represent portions of larger commercial transactions for which other institutions are the “lead banks”. Although not the lead bank, the Corporation conducts detailed underwriting and monitoring of participation loan opportunities. Total participation loans outstanding amounted to $102,228,000 at June 30, 2026, down from $107,351,000 at December 31, 2025. The Corporation is a party to financial instruments with off-balance sheet risk, including commitments to extend credit and standby letters of credit. At June 30, 2026, the total contract amount of commitments to extend credit was $474,891,000 as compared to $506,996,000 at December 31, 2025, and the contract amount of standby letters of credit was $62,133,000 at June 30, 2026 as compared to $58,914,000 at December 31, 2025. The Corporation maintains an allowance for off-balance sheet credit exposures such as unfunded balances for existing lines of credit, commitments to extend future credit, commercial letters of credit and credit enhancement obligations related to residential mortgage loans sold with recourse, when there is a contractual obligation to extend credit and when this extension of credit is not unconditionally cancellable (i.e. commitment cannot be canceled at any time). The allowance for off-balance sheet credit exposures is adjusted as a 47 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q (credit) provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. The allowance for credit losses for off-balance sheet exposures of $845,000 at June 30, 2026 and $1,029,000 at December 31, 2025, is included in accrued interest and other liabilities in the unaudited consolidated balance sheets. The Corporation originates and sells residential mortgage loans to the secondary market through the MPF Xtra program administered by the Federal Home Loan Banks of Pittsburgh and Chicago. Residential mortgages originated and sold through the MPF Xtra program consist primarily of conforming, prime loans sold to the Federal National Mortgage Association (Fannie Mae), a quasi-government entity. The Corporation also originates and sells residential mortgage loans to the secondary market through the MPF Original program, administered by the Federal Home Loan Banks of Pittsburgh and Chicago. Residential mortgages originated and sold through the MPF Original program consist primarily of conforming, prime loans sold to the Federal Home Loan Bank of Pittsburgh. The Corporation also originates and sells mortgages under the Pennsylvania Housing Finance Agency and other programs though the volume of sales has been small in comparison to the volume under the MPF programs. For loan sales originated under the MPF programs, the Corporation provides customary representations and warranties to investors that specify, among other things, that the loans have been underwritten to the standards established by the investor. The Corporation may be required to repurchase a loan and reimburse a portion of fees received or reimburse the investor for a credit loss incurred on a loan, if it is determined that the representations and warranties have not been met. Such repurchases or reimbursements generally result from an underwriting or documentation deficiency. At June 30, 2026, the total outstanding balance of loans the Corporation has repurchased as a result of identified instances of noncompliance amounted to $2,532,000, and the corresponding total outstanding balance of repurchased loans at December 31, 2025 was $2,598,000. At June 30, 2026, outstanding balances of loans sold and serviced through the MPF Xtra and Original programs totaled $454,642,000, including loans sold through the MPF Xtra program of $175,388,000 and loans sold through the Original program of $279,254,000. At December 31, 2025, outstanding balances of loans sold and serviced through the MPF Xtra and Original programs totaled $450,120,000, including loans sold through the MPF Xtra program of $177,464,000 and loans sold through the Original program of $272,656,000. Based on the fairly limited volume of required repurchases to date, no allowance has been established for representation and warranty exposures as of June 30, 2026 and December 31, 2025. ​ 48 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q TABLE VII - SUMMARY OF LOANS BY TYPE Summary of Loans by Type ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ ​ June 30, ​ December 31, ​ ​ ​ ​ 2026 ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023 ​ ​ ​ 2022 ​ ​ ​ 2021 Commercial real estate - non-owner occupied: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-owner occupied ​ $ 550,607 ​ $ 569,974 ​ $ 471,171 ​ $ 499,104 ​ $ 454,386 ​ $ 358,352 Multi-family (5 or more) residential ​ ​ 170,179 ​ ​ 160,284 ​ ​ 105,174 ​ ​ 64,076 ​ ​ 55,406 ​ ​ 49,054 1-4 Family - commercial purpose ​ ​ 203,093 ​ ​ 197,480 ​ ​ 163,220 ​ ​ 174,162 ​ ​ 165,805 ​ ​ 175,027 Total commercial real estate - non-owner occupied ​ ​ 923,879 ​ ​ 927,738 ​ ​ 739,565 ​ ​ 737,342 ​ ​ 675,597 ​ ​ 582,433 Commercial real estate - owner occupied ​ ​ 325,002 ​ ​ 311,792 ​ ​ 261,071 ​ ​ 237,246 ​ ​ 205,910 ​ ​ 196,083 All other commercial loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial and industrial ​ ​ 127,268 ​ ​ 128,679 ​ ​ 96,665 ​ ​ 78,832 ​ ​ 95,368 ​ ​ 118,488 Commercial lines of credit ​ ​ 149,546 ​ ​ 139,727 ​ ​ 120,078 ​ ​ 117,236 ​ ​ 141,444 ​ ​ 106,338 Political subdivisions ​ ​ 86,701 ​ ​ 96,349 ​ ​ 94,009 ​ ​ 79,031 ​ ​ 86,663 ​ ​ 75,401 Commercial construction and land ​ ​ 111,462 ​ ​ 123,887 ​ ​ 92,741 ​ ​ 104,123 ​ ​ 60,892 ​ ​ 59,505 Other commercial loans ​ ​ 69,098 ​ ​ 71,895 ​ ​ 19,784 ​ ​ 20,471 ​ ​ 25,710 ​ ​ 26,498 Total all other commercial loans ​ ​ 544,075 ​ ​ 560,537 ​ ​ 423,277 ​ ​ 399,693 ​ ​ 410,077 ​ ​ 386,230 Residential mortgage loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 1-4 Family - residential ​ ​ 405,339 ​ ​ 411,827 ​ ​ 383,797 ​ ​ 389,262 ​ ​ 363,005 ​ ​ 327,593 1-4 Family residential construction ​ ​ 37,737 ​ ​ 32,123 ​ ​ 24,212 ​ ​ 24,452 ​ ​ 30,577 ​ ​ 23,151 Total residential mortgage ​ ​ 443,076 ​ ​ 443,950 ​ ​ 408,009 ​ ​ 413,714 ​ ​ 393,582 ​ ​ 350,744 Consumer loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consumer lines of credit (including HELOCs) ​ ​ 98,962 ​ ​ 94,060 ​ ​ 47,196 ​ ​ 41,503 ​ ​ 36,650 ​ ​ 33,522 All other consumer ​ ​ 13,853 ​ ​ 16,288 ​ ​ 16,730 ​ ​ 18,641 ​ ​ 18,224 ​ ​ 15,837 Total consumer ​ ​ 112,815 ​ ​ 110,348 ​ ​ 63,926 ​ ​ 60,144 ​ ​ 54,874 ​ ​ 49,359 Total ​ ​ 2,348,847 ​ ​ 2,354,365 ​ ​ 1,895,848 ​ ​ 1,848,139 ​ ​ 1,740,040 ​ ​ 1,564,849 Less: allowance for credit losses on loans ​ ​ (32,583) ​ ​ (31,048) ​ ​ (20,035) ​ ​ (19,208) ​ ​ (16,615) ​ (13,537) Loans, net ​ $ 2,316,264 ​ $ 2,323,317 ​ $ 1,875,813 ​ $ 1,828,931 ​ $ 1,723,425 ​ $ 1,551,312 ​ Additional details regarding the composition of the non-owner occupied commercial real estate loan portfolio, excluding multi-family (5 or more) residential and 1-4 Family-commercial purpose loans, at June 30, 2026 and December 31, 2025 was as follows: ​ ​ NON-OWNER OCCUPIED COMMERCIAL REAL ESTATE ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ June 30, ​ % of Non-owner ​ % of ​ December 31, ​ ​ 2026 ​ Occupied CRE ​ Total Loans ​ 2025 Retail ​ $ 112,665 ​ 20.5 % ​ 4.8 % ​ $ 104,513 Office ​ ​ 107,923 ​ 19.6 % ​ 4.6 % ​ ​ 125,175 Industrial ​ ​ 96,526 ​ 17.5 % ​ 4.1 % ​ ​ 99,476 Hotels ​ ​ 76,171 ​ 13.8 % ​ 3.2 % ​ ​ 82,692 Self Storage Facilities ​ ​ 59,772 ​ 10.9 % ​ 2.5 % ​ ​ 55,434 Mixed Use ​ ​ 58,871 ​ 10.7 % ​ 2.5 % ​ ​ 64,390 Other ​ ​ 38,679 ​ 7.0 % ​ 1.6 % ​ ​ 38,294 Total Non-owner Occupied CRE Loans ​ $ 550,607 ​ 100.0 % ​ 23.4 % ​ $ 569,974 Total Gross Loans ​ $ 2,348,847 ​ ​ ​ ​ ​ ​ ​ $ 2,354,365 ​ ​ 49 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q PROVISION AND ALLOWANCE FOR CREDIT LOSSES A summary of the (credit) provision for credit losses for the three-month and six-month periods ended June 30, 2026 and 2025 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ 3 Months ​ 3 Months ​ 6 Months ​ 6 Months ​ ​ Ended ​ Ended ​ Ended ​ Ended ​ ​ June 30, ​ June 30, ​ June 30, ​ June 30, ​ ​ 2026 ​ 2025 ​ 2026 ​ 2025 (Credit) provision for credit losses: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Loans receivable ​ $ (1,652) ​ $ 2,075 ​ $ 11,940 ​ $ 2,303 Off-balance sheet exposures ​ (194) ​ 279 ​ (184) ​ 287 Total (credit) provision for credit losses ​ $ (1,846) ​ $ 2,354 ​ $ 11,756 ​ $ 2,590 ​ For the quarter ended June 30, 2026, there was a credit for credit losses (reduction in expense) of $1,846,000 as compared to a provision for credit losses of $2,354,000 in the second quarter 2025. For the six months ended June 30, 2026, there was a provision for credit losses of $11,756,000, compared to a provision for credit losses of $2,590,000 in 2025. The credit for credit losses in the second quarter 2026 included the impact on the allowance for credit losses (“ACL”) of changes in qualitative factors, net recoveries of $403,000 and a reduction in loans receivable. The increase in the provision in the six months ended June 30, 2026 was driven by the impact of the elevated level of net charge-offs, including a charge-off in the first quarter 2026 of $10,056,000 on a non-owner occupied commercial real estate loan discussed in more detail in the Earnings Overview section and was partially offset by net decreases in the ACL related to changes in qualitative factors. The ACL was 1.39% of gross loans receivable at June 30, 2026, down from 1.42% at March 31, 2026 and up from 1.32% December 31, 2025 and 1.13% at June 30, 2025. As shown in Table IX, the ACL on loans individually evaluated decreased to $2,636,000 at June 30, 2026 from $2,772,000 at December 31, 2025, including an ACL of $2,414,000 at June 30, 2026 on acquired PCD loans as part of the Susquehanna acquisition. Table IX also summarizes collectively evaluated components of the ACL, including the most significant changes at June 30, 2026 as compared to December 31, 2025 summarized as follows: ● Commercial real estate loans – nonowner occupied – The collectively determined ACL increased $2,412,000, reflecting the impact of an increase in average net charge-off experience and an increase in a qualitative factor related to regional economic conditions, partially offset by reductions in qualitative factors related to regional commercial real estate values and credit concentrations. ● Residential mortgage – The collectively determined ACL increased $1,041,000, reflecting the impact of increases in qualitative factors related to residential real estate values and regional economic conditions. ● Commercial real estate – owner occupied and All other commercial loans – The collectively determined ACL decreased by a total of $1,831,000, mainly due to the net effect of reductions in qualitative factors related to regional commercial real estate values and credit concentrations, partially offset by an increase in a qualitative factor related to regional economic conditions. In the first six months of 2026, net charge-offs totaled $10,405,000, or 0.88% (annualized) of average outstanding loans. Table VIII shows annual average net charge-off rates over the prior five calendar years ranging from a high of 0.26% in 2022 to a low of 0.01% in 2023. Total nonperforming assets were $40,275,000 at June 30, 2026, up $7,162,000 from December 31, 2025. Nonperforming loans increased $7,170,000 from December 31, 2025. The increase in nonperforming assets and nonperforming loans in 2026 included the impact of classifying the nonowner occupied commercial real estate loan referenced above as nonaccrual at June 30, 2026. Table X shows that total nonperforming assets as a percentage of total assets was 1.28% at June 30, 2026, up from 1.06% at December 31, 2025. Table X 50 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q also shows that total nonperforming assets as a percentage of assets as of year-end 2021 through 2024, ranged from a high of 1.04% at December 31, 2021 to a low of 0.75% at December 31, 2023. Over the period from 2021through 2025 and the first 6 months of 2026, each period includes a few large commercial relationships that have required significant monitoring and workout efforts. As a result, a limited number of relationships may significantly impact the total amount of allowance required on individual loans and may significantly impact the (credit) provision for credit losses and the amount of total charge-offs reported in any one period. Management believes it has been prudent in its decisions concerning identification of loans requiring individual evaluation for credit loss, estimates of loss, and nonaccrual status; however, the actual losses realized from these relationships could vary materially from the ACL calculated as of June 30, 2026. Management continues to closely monitor its commercial loan relationships for credit losses and will adjust its estimates of loss and decisions concerning nonaccrual status, if appropriate. Tables VIII through X present historical data related to loans and the allowance for credit losses.

An adequate liquidity position permits the Corporation to pay creditors, compensate for unforeseen deposit fluctuations and fund unexpected loan demand. The Corporation maintains borrowing facilities with the Federal Home Loan Bank of Pittsburgh, secured by various mortgage loans. In addition, the Corporation maintains overnight borrowing facilities with several correspondent banks that provide a source of day-to-day liquidity. The Corporation has a line of credit with the Federal Reserve Bank of Philadelphia’s Discount Window. Management intends to use this line of credit as a contingency funding source. As collateral for the line, the Corporation has pledged available-for-sale debt securities with a carrying value of $24,882,000 at June 30, 2026. The Corporation’s outstanding, available, and total credit facilities at June 30, 2026 and December 31, 2025 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Outstanding ​ Available ​ Total Credit (In Thousands) ​ ​ ​ June 30, ​ ​ ​ December 31, ​ ​ ​ June 30, ​ ​ ​ December 31, ​ ​ ​ June 30, ​ ​ ​ December 31, ​ ​ 2026 ​ 2025 ​ 2026 ​ 2025 ​ 2026 ​ 2025 Federal Home Loan Bank of Pittsburgh ​ $ 166,252 ​ $ 170,922 ​ $ 971,125 ​ $ 785,822 ​ $ 1,153,138 ​ $ 971,946 Federal Reserve Bank Discount Window ​ 0 ​ 0 ​ 24,882 ​ 25,484 ​ 24,882 ​ 25,484 Other correspondent banks ​ 0 ​ 0 ​ 75,000 ​ 75,000 ​ 75,000 ​ 75,000 Total credit facilities ​ $ 166,252 ​ $ 170,922 ​ $ 1,071,007 ​ $ 886,306 ​ $ 1,253,020 ​ $ 1,072,430 ​ At June 30, 2026, the Corporation’s outstanding credit facilities with the Federal Home Loan Bank of consisted of short-term borrowings totaling $14,260,000, long-term borrowings with par values totaling $130,392,000 and letters of credit totaling $21,600,000. At December 31, 2025, the Corporation’s outstanding credit facilities with the Federal Home Loan Bank of Pittsburgh consisted of overnight borrowing of $27,000,000, long-term borrowings with par values totaling $120,935,000 and letters of credit totaling $22,987,000. Availability on the facility is also reduced by accrued interest payable on the borrowings and by the total of the Corporation’s credit enhancement obligations on residential mortgage loans sold under the MPF Original Program. Additional information regarding borrowed funds is included in Note 9 to the unaudited consolidated financial statements. Additionally, the Corporation uses “RepoSweep” arrangements to borrow funds from commercial banking customers on an overnight basis. If required to raise cash in an emergency situation, the Corporation could sell available-for-sale securities to meet its obligations or use repurchase agreements placed with brokers to borrow funds secured by investment assets. At June 30, 2026, the carrying value of available-for-sale securities in excess of amounts required to meet pledging or repurchase agreement obligations was $316,129,000. Deposits totaled $2,603,735,000 at June 30, 2026, up $39,019,000 from December 31, 2025. Average total deposits were $493,355,000 or 23.8% higher for the six months ended June 30, 2026 as compared to the first six months of 2025 . Deposits of $501,488,000 were assumed from Susquehanna, effective October 1, 2025. As shown in the table below, at June 30, 2026, estimated uninsured deposits totaled $820.2 million, or 31.4%, of total deposits, as compared to $811.2 million, or 31.4% of total deposits at December 31, 2025. Included in uninsured deposits are deposits collateralized by securities (almost exclusively municipal deposits) totaling $167.8 million at June 30, 2026. As shown in the table below, total uninsured and uncollateralized deposits amounted to 25.0% of total deposits at June 30, 2026, as compared to 24.7% of total deposits at December 31, 2025. As summarized in the table that immediately follows, the Corporation’s highly liquid sources of available funds described above, including unused borrowing capacity with the Federal Home Loan Bank of Pittsburgh, unused availability on the Federal Reserve Bank of Philadelphia’s discount window, available federal funds lines with other banks and unencumbered available-for-sale debt securities, totaled $1.4 billion at June 30, 2026. Available funding from these sources totaled 169.1% of uninsured deposits and 212.6% of total uninsured and uncollateralized deposits at June 30, 2026. 53 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q ​ ​ ​ ​ ​ ​ ​ ​ Uninsured Deposits Information ​ June 30, December 31, ​ ​ 2026 2025 Total Deposits - C&N Bank ​ $ 2,610,552 ​ $ 2,584,952 ​ ​ ​ ​ ​ ​ ​ ​ ​ Estimated Total Uninsured Deposits ​ $ 820,235 ​ $ 811,209 ​ Portion of Uninsured Deposits that are ​ ​ ​ ​ ​ ​ ​ Collateralized ​ ​ 167,823 ​ ​ 172,585 ​ Uninsured and Uncollateralized Deposits ​ $ 652,412 ​ $ 638,624 ​ ​ ​ ​ ​ ​ ​ ​ ​ Uninsured and Uncollateralized Deposits as ​ ​ ​ ​ ​ ​ ​ a % of Total Deposits ​ ​ 25.0 % ​ 24.7 % ​ ​ ​ ​ ​ ​ ​ ​ Available Funding from Credit Facilities ​ $ 1,071,007 ​ $ 886,306 ​ Fair Value of Available-for-sale Debt ​ ​ ​ ​ ​ ​ ​ Securities in Excess of Pledging Obligations ​ ​ 316,129 ​ ​ 319,624 ​ Highly Liquid Available Funding ​ $ 1,387,136 ​ $ 1,205,930 ​ ​ ​ ​ ​ ​ ​ ​ ​ Highly Liquid Available Funding as a % of ​ ​ ​ ​ ​ ​ ​ Uninsured Deposits ​ ​ 169.1 % ​ 148.7 % ​ ​ ​ ​ ​ ​ ​ ​ Highly Liquid Available Funding as a % of ​ ​ ​ ​ ​ ​ ​ Uninsured and Uncollateralized Deposits ​ ​ 212.6 % ​ 188.8 % Based on the ample sources of highly liquid funds as described above, management believes the Corporation is well-positioned to meet its short-term and long-term funding obligations. STOCKHOLDERS’ EQUITY AND CAPITAL ADEQUACY Details concerning capital ratios at June 30, 2026 and December 31, 2025 are presented below. Management believes, as of June 30, 2026, that the Corporation and C&N Bank meet all capital adequacy requirements to which they are subject and maintain a capital conservation buffer (described in more detail below) that allows the Corporation and C&N Bank to avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers. Further, as reflected in the table below, the Corporation’s and C&N Bank’s capital ratios at June 30, 2026 and December 31, 2025 exceed the Corporation’s Board policy threshold levels. 54 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (Dollars in Thousands) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum To Be ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum To Maintain ​ ​ ​ Well ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum ​ ​ ​ Capital Conservation ​ ​ ​ Capitalized Under ​ ​ Minimum To Meet ​ ​ ​ ​ ​ ​ ​ ​ ​ Capital ​ ​ ​ Buffer at Reporting ​ ​ ​ Prompt Corrective ​ ​ the Corporation's ​ ​ Actual ​ ​ ​ Requirement ​ ​ ​ Date ​ ​ ​ Action Provisions ​ ​ Policy Thresholds ​ ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ ​ Amount ​ ​ ​ Ratio June 30, 2026: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total capital to risk-weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 348,687 14.52 % $ 192,064 ​ ≥8 % ​ $ 252,085 ​ ≥10.5 % ​ $ 240,081 ​ ≥10 % ​ $ 264,089 ​ ≥11 % C&N Bank ​ 338,125 14.10 % ​ 191,854 ≥8 % ​ ​ 251,808 ≥10.5 % ​ ​ 239,817 ≥10 % ​ ​ 263,799 ≥11 % Tier 1 capital to risk-weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 298,665 12.44 % ​ 144,048 ≥6 % ​ ​ 204,068 ≥8.5 % ​ ​ 192,064 ≥8 % ​ ​ 216,072 ≥9 % C&N Bank ​ 308,136 12.85 % ​ 143,890 ≥6 % ​ ​ 203,844 ≥8.5 % ​ ​ 191,854 ≥8 % ​ ​ 215,835 ≥9 % Common equity tier 1 capital to risk-weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 298,665 12.44 % ​ 108,036 ≥4.5 % ​ ​ 168,056 ≥7.0 % ​ ​ 156,052 ≥6.5 % ​ ​ 180,060 ≥7.5 % C&N Bank ​ 308,136 12.85 % ​ 107,918 ≥4.5 % ​ ​ 167,892 ≥7.0 % ​ ​ 155,811 ≥6.5 % ​ ​ 179,863 ≥7.5 % Tier 1 capital to average assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ 298,665 9.62 % ​ 124,145 ≥4 % ​ ​ N/A N/A ​ ​ 155,181 ≥5 % ​ ​ 248,290 ≥8 % C&N Bank ​ 308,136 9.96 % ​ 123,687 ≥4 % ​ ​ N/A N/A ​ ​ 154,609 ≥5 % ​ ​ 247,375 ≥8 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total capital to risk-weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 346,139 14.45 % $ 191,582 ​ ≥8 % ​ $ 251,452 ​ ≥10.5 % ​ $ 239,478 ​ ≥10 % ​ $ 263,425 ​ ≥11 % C&N Bank ​ ​ 330,427 13.82 % ​ 191,318 ≥8 % ​ ​ 251,105 ≥10.5 % ​ ​ 239,148 ≥10 % ​ ​ 263,062 ≥11 % Tier 1 capital to risk-weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ ​ 291,746 12.18 % ​ 143,687 ≥6 % ​ ​ 203,556 ≥8.5 % ​ ​ 191,582 ≥8 % ​ ​ 215,530 ≥9 % C&N Bank ​ ​ 300,983 12.59 % ​ 143,489 ≥6 % ​ ​ 203,275 ≥8.5 % ​ ​ 191,318 ≥8 % ​ ​ 215,233 ≥9 % Common equity tier 1 capital to risk-weighted assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ ​ 291,746 12.18 % ​ 107,765 ≥4.5 % ​ ​ 167,634 ≥7.0 % ​ ​ 155,661 ≥6.5 % ​ ​ 179,608 ≥7.5 % C&N Bank ​ ​ 300,983 12.59 % ​ 107,616 ≥4.5 % ​ ​ 167,403 ≥7.0 % ​ ​ 155,446 ≥6.5 % ​ ​ 179,361 ≥7.5 % Tier 1 capital to average assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ ​ 291,746 9.32 % ​ 125,149 ≥4 % ​ ​ N/A N/A ​ ​ 156,437 ≥5 % ​ ​ 250,299 ≥8 % C&N Bank ​ ​ 300,983 9.66 % ​ 124,597 ≥4 % ​ ​ N/A N/A ​ ​ 155,747 ≥5 % ​ ​ 249,195 ≥8 % ​ To avoid limitations on capital distributions, including dividend payments and certain discretionary bonus payments to executive officers, a banking organization subject to the rule must hold a capital conservation buffer composed of common equity tier 1 capital above its minimum risk-based capital requirements. The buffer is measured relative to risk-weighted assets. At June 30, 2026, the minimum risk-based capital ratios, and the capital ratios including the capital conservation buffer, were as follows: ​ ​ ​ ​ ​ Minimum common equity tier 1 capital ratio ​ ​ ​ 4.5 % Minimum common equity tier 1 capital ratio plus capital conservation buffer 7.0 % Minimum tier 1 capital ratio 6.0 % Minimum tier 1 capital ratio plus capital conservation buffer 8.5 % Minimum total capital ratio 8.0 % Minimum total capital ratio plus capital conservation buffer 10.5 % ​ A banking organization with a buffer greater than 2.5% over the minimum risk-based capital ratios would not be subject to additional limits on dividend payments or discretionary bonus payments; however, a banking organization with a buffer less than 2.5% would be subject to increasingly stringent limitations as the buffer approaches zero. Also, a banking organization is prohibited from making dividend payments or discretionary bonus payments if its eligible retained income is negative in that quarter and its capital conservation buffer ratio was less than 2.5% as of the beginning of that quarter. Eligible net income is defined as net income for the four calendar quarters preceding the current calendar quarter, net of any distributions and associated tax effects not already reflected in net income. A summary of payout restrictions based on the capital conservation buffer is as follows: 55 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q ​ ​ ​ ​ Capital Conservation Buffer ​ ​ ​ Maximum Payout (as a % of risk-weighted assets) ​ (as a % of eligible retained income) Greater than 2.5% ​ No payout limitation applies ​ ≤2.5% and >1.875% ​ 60 % ≤1.875% and >1.25% ​ 40 % ≤1.25% and >0.625% ​ 20 % ≤0.625% ​ 0 % ​ At June 30, 2026 , the Corporation’s Capital Conservation Buffer was 6.44% and C&N Bank’s Capital Conservation Buffer was 6.10%. On September 25, 2023, the Corporation announced a treasury stock repurchase program with no expiration that can be suspended or terminated by the Board of Directors, in its sole discretion. Under this program, the Corporation is authorized to repurchase up to 750,000 shares of its common stock. There were no shares repurchased during the first six months of 2026. At June 30, 2026, there were 723,465 shares available to be repurchased under the program. Future dividend payments and repurchases of common stock will depend upon maintenance of a strong financial condition, future earnings and capital and regulatory requirements. In addition, the Corporation and C&N Bank are subject to restrictions on the amount of dividends that may be paid without approval of banking regulatory authorities. The Corporation’s ability to pay dividends, repurchase stock or engage in other activities may be limited by the Federal Reserve if the Corporation fails to hold capital commensurate with its overall risk profile. The Corporation’s total stockholders’ equity is affected by fluctuations in the fair values of available-for-sale debt securities. The difference between amortized cost and fair value of available-for-sale debt securities, net of deferred income tax, is included in accumulated other comprehensive (loss) income within stockholders’ equity. Accumulated other comprehensive (loss) income is excluded from the Bank’s and the Corporation’s regulatory capital ratios. The balance in accumulated other comprehensive loss related to unrealized losses on available-for-sale debt securities, net of deferred income tax, amounted to $24,284,000 at June 30, 2026 and $23,154,000 at December 31, 2025. Changes in accumulated other comprehensive loss are excluded from earnings and directly increase or decrease stockholders’ equity. To the extent unrealized losses on available-for-sale debt securities result from credit losses, unrealized losses are recorded as a charge against earnings. The securities section of Management’s Discussion and Analysis and Note 6 to the unaudited consolidated financial statements provide additional information concerning management’s evaluation of available-for-sale debt securities for credit losses at June 30, 2026. Tangible common equity is a non- U.S. GAAP measure, and tangible common book value per share and tangible common equity as a percentage of tangible assets are non- U.S. GAAP ratios. Management believes this non- U.S. GAAP information is helpful in evaluating the strength of the Corporation’s capital and in providing an alternative presentation of the Corporation’s net worth.
