BASIS OF INTERIM PRESENTATION AND STATUS OF RECENT ACCOUNTING PRONOUNCEMENTS The consolidated financial statements include the accounts of Citizens & Northern Corporation and its subsidiaries, Citizens & Northern Bank (“C&N Bank”), Bucktail Life Insurance Company and Citizens & Northern Investment Corporation (collectively, “Corporation”). The consolidated financial statements also include C&N Bank’s wholly-owned subsidiaries, C&N Financial Services, LLC and Northern Tier Holding LLC. C&N Bank is the sole member of C&N Financial Services, LLC and Northern Tier Holding LLC. All material intercompany balances and transactions have been eliminated in consolidation. The consolidated financial information included herein, except the consolidated balance sheet dated December 31, 2023, is unaudited. Such information reflects all adjustments (consisting solely of normal recurring adjustments) that are, in the opinion of management, necessary for a fair presentation of the financial position, results of operations, comprehensive income, cash flows and changes in stockholders’ equity for the interim periods; however, the information does not include all disclosures required by accounting principles generally accepted in the United States of America (“U.S. GAAP”) for a complete set of financial statements. Operating results reported for the three-month period ended March 31, 2024 might not be indicative of the results for the year ending December 31, 2024. The Corporation evaluates subsequent events through the date of filing with the Securities and Exchange Commission. RECENT ACCOUNTING PRONOUNCEMENTS The Financial Accounting Standards Board (FASB) issues Accounting Standard Updates (ASUs) to communicate changes to the FASB Accounting Standard Codification (ASC). This section provides a summary description of recent ASUs that have significant implications (elected or required) within the consolidated financial statements, or that management expects may have a significant impact on financial statements issued in the foreseeable future. CECL ADOPTION On January 1, 2023, the Corporation adopted ASU 2016-13 Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASC 326). This standard replaced the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The Corporation adopted ASC 326 using the modified retrospective approach for all financial assets measured at amortized cost and off-balance sheet credit exposures. The following table illustrates the impact on the allowance for credit losses from the adoption of ASC 326: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As Reported ​ ​ ​ ​ Under ​ Pre-ASC 326 ​ Impact of ​ ​ ASC 326 ​ Adoption ​ ASC 326 (In Thousands) ​ January 1, 2023 ​ December 31, 2022 ​ Adoption Loans receivable ​ $ 1,740,846 ​ $ 1,740,040 ​ $ 806 Allowance for credit losses on loans ​ ​ 18,719 ​ ​ 16,615 ​ ​ 2,104 Allowance for credit losses on off-balance sheet exposures (included in accrued interest and other liabilities) ​ 1,218 ​ 425 ​ 793 Deferred tax asset, net ​ 21,323 ​ 20,884 ​ 439 Retained earnings ​ 150,091 ​ 151,743 ​ ( 1,652 ) ​ Recent Issued but Not Yet Effective Accounting Pronouncements In December 2023 , the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures which improves the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. ASU No. 2023-09 is effective for public business entities 8 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q for annual periods beginning after December 15, 2024. The ASU may be adopted on a prospective or retrospective basis and early adoption is permitted. The Corporation is currently evaluating the impact the new guidance will have on disclosures related to income taxes. 2. PER SHARE DATA Basic earnings per common share are calculated using the two-class method to determine income attributable to common shareholders. Unvested restricted stock awards that contain nonforfeitable rights to dividends are considered participating securities under the two-class method. Distributed dividends and an allocation of undistributed net income to participating securities reduce the amount of income attributable to common shareholders. Income attributable to common shareholders is then divided by weighted-average common shares outstanding for the period to determine basic earnings per common share. Diluted earnings per common share are calculated under the more dilutive of either the treasury method or the two-class method. Diluted earnings per common share is computed using weighted-average common shares outstanding, plus weighted-average common shares available from the exercise of all dilutive stock options, less the number of shares that could be repurchased with the proceeds of stock option exercises based on the average share price of the Corporation’s common stock during the period. ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands, Except Share and Per Share Data) Three Months Ended ​ ​ March 31, ​ March 31, ​ ​ 2024 2023 Basic ​ ​ Net income ​ $ 5,306 ​ $ 6,253 ​ Less: Dividends and undistributed earnings allocated to participating securities ​ ( 39 ) ​ ( 52 ) ​ Net income attributable to common shares ​ $ 5,267 ​ $ 6,201 ​ Basic weighted-average common shares outstanding ​ 15,230,580 ​ 15,409,680 ​ Basic earnings per common share (a) ​ $ 0.35 ​ $ 0.40 ​ Diluted ​ ​ ​ Net income attributable to common shares ​ $ 5,267 ​ $ 6,201 ​ Basic weighted-average common shares outstanding ​ 15,230,580 ​ 15,409,680 ​ Dilutive effect of potential common stock arising from stock options ​ ​ ​ 937 ​ Diluted weighted-average common shares outstanding ​ 15,230,580 ​ 15,410,617 ​ Diluted earnings per common share (a) ​ $ 0.35 ​ $ 0.40 ​ Weighted-average nonvested restricted shares outstanding ​ 113,084 ​ 128,435 ​ (a) Basic and diluted earnings per share under the two-class method are determined on net income reported on the consolidated statements of income, less earnings allocated to non-vested restricted shares with nonforfeitable dividends (participating securities). Anti-dilutive stock options are excluded from earnings per share calculations. There were no anti-dilutive instruments outstanding in the three-month periods ended March 31, 2024 and 2023. ​ 9 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q 3.

Cash flows from such investments are dependent upon the performance of the underlying mortgage loans and are generally influenced by the level of interest rates. In the table above, mortgage-backed securities and collateralized mortgage obligations are shown in one period. 13 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q Investment securities carried at $ 183,661,000 at March 31, 2024 and $ 232,437,000 at December 31, 2023 were pledged as collateral for public deposits, trusts and certain other deposits as provided by law. See Note 8 for information concerning securities pledged to secure borrowing arrangements and Note 11 for information related to securities pledged against interest rate swap obligations. A summary of information management considered in evaluating debt and equity securities for credit losses at March 31, 2024 and December 31, 2023 is provided below. Debt Securities As reflected in the table above, gross unrealized holding losses on available-for-sale debt securities totaled $ 52,272,000 at March 31, 2024 and $ 49,564,000 at December 31, 2023. At March 31, 2024, the Corporation does not have the intent to sell, nor is it more likely than not it will be required to sell, these securities before it is able to recover the amortized cost basis. The unrealized holding losses were consistent with significant increases in market interest rates that have occurred subsequent to the purchase of most of the securities. At March 31, 2024 and December 31, 2023, management performed an assessment for possible credit losses of the Corporation’s debt securities on an issue-by-issue basis, relying on information obtained from various sources, including publicly available financial data, ratings by external agencies, brokers and other sources. At March 31, 2024 and December 31, 2023, all of the Corporation’s holdings of bank holding company debt securities, obligations of states and political subdivisions and private label commercial mortgage-backed securities were investment grade and there have been no payment defaults. Based on the results of the assessment, there was no allowance for credit losses (“ACL”) required on available-for-sale debt securities in an unrealized loss position at March 31, 2024 and December 31, 2023. Equity Securities C&N Bank is a member of the Federal Home Loan Bank of Pittsburgh (FHLB-Pittsburgh), which is one of 11 regional Federal Home Loan Banks. As a member, C&N Bank is required to purchase and maintain stock in FHLB-Pittsburgh. There is no active market for FHLB-Pittsburgh stock, and it must ordinarily be redeemed by FHLB-Pittsburgh in order to be liquidated. C&N Bank’s investment in FHLB-Pittsburgh stock, included in other assets in the consolidated balance sheets, was $ 16,266,000 at March 31, 2024 and $ 15,214,000 at December 31, 2023. The Corporation evaluated its holding of FHLB-Pittsburgh stock for impairment and deemed the stock to not be impaired at March 31, 2024 and December 31, 2023. In making this determination, management concluded that recovery of total outstanding par value, which equals the carrying value, is expected. The decision was based on review of financial information that FHLB-Pittsburgh has made publicly available. In July 2023, C&N Bank became a member of the Federal Reserve System. As a member, C&N Bank is required to purchase and maintain stock in the Federal Reserve Bank of Philadelphia. There is no active market for Federal Reserve Bank stock, and it must ordinarily be redeemed by the Federal Reserve Bank of Philadelphia in order to be liquidated. C&N Bank’s investment in Federal Reserve Bank stock, included in other assets in the consolidated balance sheets, was $ 6,266,000 at March 31, 2024 and $ 6,252,000 at December 31, 2023. The Corporation has a marketable equity security included in other assets in the consolidated balance sheets with a carrying value of $ 862,000 at March 31, 2024 and $ 871,000 December 31, 2023, consisting exclusively of one mutual fund. There was an unrealized loss on the mutual fund of $ 138,000 at March 31, 2024 and $ 129,000 at December 31, 2023. Changes in the unrealized gains or losses on this security, which are included in other noninterest income in the consolidated statements of income, were a loss of $ 9,000 in the first quarter 2024 compared to a gain of $ 14,000 in the first quarter 2023. ​ 14 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q 6.

The Corporation grants loans to individuals as well as commercial and tax-exempt entities. Commercial, residential and personal loans are made to customers geographically concentrated in Northcentral Pennsylvania, the Southern tier of New York State, Southeastern Pennsylvania and Southcentral Pennsylvania. Although the Corporation has a diversified loan portfolio, a significant portion of its debtors’ ability to honor their contracts is dependent on the local economic conditions within the region. Acquired loans were initially recorded at fair value, with adjustments made to gross amortized cost based on movements in interest rates (market rate adjustment) and based on credit fair value adjustments on non-impaired loans and impaired loans. Subsequently, the Corporation has recognized amortization and accretion of a portion of the market rate adjustments and credit adjustments on performing loans. For the three-month periods ended March 31, 2024 and 2023, adjustments to the initial market rate and credit fair value adjustments of performing loans were recognized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ Three Months Ended ​ ​ ​ March 31, ​ March 31, ​ ​ ​ 2024 ​ 2023 ​ Market Rate Adjustment ​ ​ Adjustments to gross amortized cost of loans at beginning of period ​ $ ( 970 ) ​ $ ( 916 ) ​ Accretion (amortization) recognized in interest income ​ ​ 28 ​ ​ ( 52 ) ​ Adjustments to gross amortized cost of loans at end of period ​ $ ( 942 ) ​ $ ( 968 ) ​ Credit Adjustment on Non-impaired Loans ​ ​ ​ ​ ​ ​ ​ Adjustments to gross amortized cost of loans at beginning of period ​ $ ( 1,163 ) ​ $ ( 1,840 ) ​ Accretion recognized in interest income ​ 115 ​ 198 ​ Adjustments to gross amortized cost of loans at end of period ​ $ ( 1,048 ) ​ $ ( 1,642 ) ​ ​ 15 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q The following tables presents an analysis of past due loans as of March 31, 2024 and December 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ As of March 31, 2024 ​ ​ Past Due ​ Past Due ​ ​ ​ ​ ​ ​ ​ ​ ​ 30-89 ​ 90+ ​ Nonaccrual ​ Current ​ Total ​ ​ Days ​ Days ​ Loans ​ Loans ​ Loans Commercial real estate - non-owner occupied ​ $ 69 ​ $ 201 ​ $ 8,430 ​ $ 731,129 ​ $ 739,829 Commercial real estate - owner occupied ​ 799 ​ 0 ​ 2,304 ​ 247,042 ​ 250,145 All other commercial loans ​ ​ 368 ​ ​ 0 ​ ​ 4,071 ​ ​ 408,366 ​ ​ 412,805 Residential mortgage loans ​ ​ 4,738 ​ ​ 0 ​ ​ 3,947 ​ ​ 400,978 ​ ​ 409,663 Consumer loans ​ 586 ​ 26 ​ 317 ​ 59,078 ​ 60,007 Total ​ $ 6,560 ​ $ 227 ​ $ 19,069 ​ $ 1,846,593 ​ $ 1,872,449 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ As of December 31, 2023 ​ ​ Past Due ​ Past Due ​ ​ ​ ​ ​ ​ ​ ​ ​ 30-89 ​ 90+ ​ Nonaccrual ​ Current ​ Total ​ ​ Days ​ Days ​ Loans ​ Loans ​ Loans Commercial real estate - non-owner occupied ​ $ 2,215 ​ $ 126 ​ $ 8,412 ​ $ 726,589 ​ $ 737,342 Commercial real estate - owner occupied ​ 849 ​ 0 ​ 1,575 ​ 234,822 ​ 237,246 All other commercial loans ​ ​ 229 ​ ​ 2,593 ​ ​ 1,323 ​ ​ 395,548 ​ ​ 399,693 Residential mortgage loans ​ ​ 5,365 ​ ​ 326 ​ ​ 3,627 ​ ​ 404,396 ​ ​ 413,714 Consumer loans ​ ​ 617 ​ 145 ​ 240 ​ 59,142 ​ 60,144 Total ​ $ 9,275 ​ $ 3,190 ​ $ 15,177 ​ $ 1,820,497 ​ $ 1,848,139 ​ The Corporation uses an internal risk rating system. Under the risk rating system, the Corporation classifies problem or potential problem loans as “Special Mention,” “Substandard,” or “Doubtful” on the basis of currently existing facts, conditions and values. Loans that do not currently expose the Corporation to sufficient risk to warrant classification as Substandard or Doubtful, but possess weaknesses that deserve management’s close attention, are deemed to be Special Mention. Substandard loans include those characterized by the distinct possibility that the Corporation will sustain some loss if the deficiencies are not corrected. Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard with the added characteristic that the weaknesses present make collection or liquidation in full, on the basis of currently existing facts, conditions and values, highly questionable and improbable. Risk ratings are updated any time that conditions or the situation warrants. Loans not classified are included in the “Pass” rows in the table that follows. ​ 16 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q The following table presents the recorded investment in loans by credit quality indicators by year of origination as of March 31, 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ Term Loans by Year of Origination ​ ​ ​ ​ ​ ​ ​ ​ 2024 ​ 2023 ​ 2022 ​ 2021 ​ 2020 ​ Prior ​ Revolving ​ Total Commercial real estate -

The underlying collateral can vary based upon the type of loan. The following provides more detail about the types of collateral that secure collateral dependent loans: ● Commercial real estate loans can be secured by either owner occupied commercial real estate or non-owner occupied investment commercial real estate. Typically, owner occupied commercial real estate loans are secured by office buildings, warehouses, manufacturing facilities and other commercial and industrial properties occupied by operating companies. Non-owner occupied commercial real estate loans are generally secured by office buildings and complexes, retail facilities, multifamily complexes, land under development, industrial properties, as well as other commercial or industrial real estate. ● All other commercial loans include loans typically secured by business assets including inventory, equipment and receivables. Also within this category, commercial construction and land loans and some commercial lines of credit are secured by real estate. ● Residential mortgage loans are typically secured by first mortgages, and in some cases could be secured by a second mortgage. ● Consumer loans are generally secured by automobiles, motorcycles, recreational vehicles and other personal property. Some consumer loans are unsecured and have no underlying collateral. 19 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q The following table details the amortized cost of collateral dependent loans, which are individually evaluated to determine expected credit losses, and the related allowance for credit losses on loans allocated to these loans: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2024 ​ December 31, 2023 ​ ​ Amortized ​ ​ ​ Amortized ​ ​ (In Thousands) ​ Cost ​ Allowance ​ Cost ​ Allowance Commercial real estate - non-owner occupied ​ $ 8,430 ​ $ 623 ​ $ 8,412 ​ $ 648 Commercial real estate - owner occupied ​ 2,304 ​ 244 ​ 1,575 ​ 5 All other commercial loans ​ ​ 4,071 ​ ​ 536 ​ ​ 1,277 ​ ​ 90 Total ​ $ 14,805 ​ $ 1,403 ​ $ 11,264 ​ $ 743 ​ The following table summarizes the activity related to the allowance for credit losses for the three-month periods ended March 31, 2024 and 2023. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ Commercial ​ All ​ ​ ​ ​ ​ ​ ​ ​ ​ real estate - ​ real estate - ​ other ​ Residential ​ ​ ​ ​ ​ ​ nonowner ​ owner ​ commercial ​ mortgage ​ Consumer ​ ​ ​ (In Thousands) occupied ​ occupied ​ loans ​ loans ​ loans ​ Total Balance, December 31, 2023 $ 12,010 ​ $ 2,116 ​ $ 2,918 ​ $ 1,764 ​ $ 400 ​ $ 19,208 Charge-offs ​ 0 ​ ​ 0 ​ ​ ( 60 ) ​ ​ 0 ​ ​ ( 120 ) ​ ​ ( 180 ) Recoveries ​ 0 ​ ​ 0 ​ ​ 20 ​ ​ 3 ​ ​ 12 ​ ​ 35 Provision (credit) for credit losses on loans 523 ​ 602 ​ 702 ​ ( 998 ) ​ 131 ​ 960 Balance, March 31, 2024 $ 12,533 ​ $ 2,718 ​ $ 3,580 ​ $ 769 ​ $ 423 ​ $ 20,023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ Commercial ​ All ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ real estate - ​ real estate - ​ other ​ Residential ​ ​ ​ ​ ​ ​ ​ ​ ​ nonowner ​ owner ​ commercial ​ mortgage ​ Consumer ​ ​ ​ ​ ​ (In Thousands) occupied ​ occupied ​ loans ​ loans ​ loans ​ Unallocated ​ Total Balance, December 31, 2022 $ 6,305 ​ $ 1,942 ​ $ 4,142 ​ $ 2,751 ​ $ 475 ​ $ 1,000 ​ $ 16,615 Adoption of ASU 2016-13 (CECL) ​ 3,763 ​ ​ 7 ​ ​ ( 88 ) ​ ​ ( 344 ) ​ ​ ( 234 ) ​ ​ ( 1,000 ) ​ ​ 2,104 Charge-offs ​ 0 ​ ​ 0 ​ ​ ( 5 ) ​ ​ ( 19 ) ​ ​ ( 43 ) ​ ​ 0 ​ ​ ( 67 ) Recoveries ​ 0 ​ ​ 0 ​ ​ 0 ​ ​ 1 ​ ​ 5 ​ ​ 0 ​ ​ 6 (Credit) provision for credit losses on loans ( 414 ) ​ ( 7 ) ​ ( 469 ) ​ 475 ​ 103 ​ 0 ​ ( 312 ) Balance, March 31, 2023 $ 9,654 ​ $ 1,942 ​ $ 3,580 ​ $ 2,864 ​ $ 306 ​ $ 0 ​ $ 18,346 ​ Modifications Made to Borrowers Experiencing Financial Difficulty ​ The Corporation closely monitors the performance of the loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification. During the three months ended March 31, 2024 and March 31, 2023, the Corporation had no modifications to borrowers experiencing financial difficulty. ​ The Corporation closely monitors the performance of the loans modified to borrowers experiencing financial difficultly to understand the effectiveness of its modification efforts.

The allowance for off-balance sheet credit exposures is adjusted as a 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 $ 684,000 at March 31, 2024 and $ 690,000 at December 31, 2023, is included in accrued interest and other liabilities on the unaudited consolidated balance sheets. ​ The following table presents the balance and activity in the allowance for credit losses for off-balance sheet exposures for the three-months period ended March 31 2024 and 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months ​ Three Months ​ ​ Ended ​ Ended (In Thousands) ​ March 31, 2024 ​ March 31, 2023 Beginning Balance ​ $ 690 ​ $ 425 Adjustment to allowance for off-balance sheet exposures for adoption of ASU 2016-13 ​ ​ 0 ​ ​ 793 Credit for unfunded commitments ​ ​ ( 6 ) ​ ​ ( 40 ) Ending Balance, March 31 ​ $ 684 ​ $ 1,178 ​ ​ ​ ​ ​ 21 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q 7.

Accordingly, no accrual or range of loss has been included in the accompanying financial statements. Other Matters In the normal course of business, the Corporation is subject to pending and threatened litigation in which claims for monetary damages are asserted. In management’s opinion, the Corporation’s financial position and results of operations would not be materially affected by the outcome of these legal proceedings. ​ 11. DERIVATIVE FINANCIAL INSTRUMENTS The Corporation is a party to derivative financial instruments. These financial instruments consist of interest rate swap agreements and risk participation agreements (RPAs) which contain master netting and collateral provisions designed to protect the party at risk. Interest rate swaps with commercial loan banking customers were executed to facilitate their respective risk management strategies. Under the terms of these arrangements, the commercial banking customers effectively exchanged their floating interest rate exposures on loans into fixed interest rate exposures. Those interest rate swaps have been simultaneously economically hedged by offsetting interest rate swaps with a third party, such that the Corporation has effectively exchanged its fixed interest rate exposures for floating rate exposures. These derivatives are not designated as hedges and are not speculative. Rather, these derivatives result from a service provided to certain customers. As the interest rate swaps associated with this program do not meet the hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. The aggregate notional amount of interest rate swaps was $ 148,838,000 at March 31, 2024 and $ 150,028,000 at December 31, 2023. There were no interest rate swaps originated in the periods ended March 31, 2024, and 2023. There were no gross amounts of interest rate swap-related assets and liabilities not offset in the consolidated balance sheets at March 31, 2024. The net impact on the consolidated statements of income from interest rate swaps was an increase in interest income on loans of $ 498,000 in the first quarter 2024 and $ 345,000 in the first quarter 2023. The Corporation has entered into an RPA with another institution as a means to assume a portion of the credit risk associated with a loan structure which includes a derivative instrument, in exchange for fee income commensurate with the risk assumed. This type of derivative is referred to as an “RPA In.” In addition, in an effort to reduce the credit risk associated with an interest rate swap agreement with a borrower for whom the Corporation has provided a loan structured with a derivative, the Corporation purchased an RPA from an institution participating in the facility in exchange for a fee commensurate with the risk shared. This type of derivative is referred to as an “RPA Out.” The net impact on the consolidated statements of income from RPAs was an increase in other noninterest income of $ 1,000 in the first quarter 2024 and $ 16,000 in the first quarter 2023. The table below presents the fair value of the Corporation’s derivative financial instruments as well as their classification on the consolidated balance sheets at March 31, 2024 and December 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) At March 31, 2024 ​ At December 31, 2023 ​ Asset Derivatives ​ Liability Derivatives ​ Asset Derivatives ​ Liability Derivatives ​ Notional ​ Fair ​ Notional ​ Fair ​ Notional ​ Fair ​ Notional ​ Fair ​ Amount ​ Value (1) ​ Amount ​ Value (2) ​ Amount ​ Value (1) ​ Amount ​ Value (2) Interest rate swap agreements $ 74,419 ​ $ 3,222 ​ $ 74,419 ​ $ 3,222 ​ $ 75,014 ​ $ 2,783 ​ $ 75,014 ​ $ 2,783 RPA Out ​ 7,051 ​ ​ 5 ​ ​ 0 ​ ​ 0 ​ ​ 7,082 ​ ​ 11 ​ ​ 0 ​ ​ 0 RPA In ​ 0 ​ ​ 0 ​ ​ 10,000 ​ ​ 5 ​ ​ 0 ​ ​ 0 ​ ​ 10,000 ​ ​ 13 ​ (1) Included in other assets in the consolidated balance sheets.

Further, if the Corporation were to fail to maintain its status as a well or adequately capitalized institution, then the counterparties could terminate the derivative positions and the Corporation would be required to settle its obligations under the agreements. There was interest-bearing cash pledged as collateral against the Corporation’s liability related to the interest rate swaps of $ 1,140,000 at March 31, 2024 and $ 1,360,000 at December 31, 2023. 12. FAIR VALUE MEASUREMENTS AND FAIR VALUES OF FINANCIAL INSTRUMENTS The Corporation measures certain assets and liabilities at fair value. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. FASB Topic 820, “Fair Value Measurements and Disclosures” establishes a framework for measuring fair value that includes a hierarchy used to classify the inputs used in measuring fair value. The hierarchy prioritizes the inputs used in determining valuations into three levels. The level in the fair value hierarchy within which the fair value measurement falls is determined based on the lowest level input that is significant to the fair value measurement. The levels of the fair value hierarchy are as follows: Level 1 – Fair value is based on unadjusted quoted prices in active markets that are accessible to the Corporation for identical assets or liabilities. These generally provide the most reliable evidence and are used to measure fair value whenever available. Level 2 – Fair value is based on significant inputs, other than Level 1 inputs, that are observable either directly or indirectly for substantially the full term of the asset or liability through corroboration with observable market data. Level 2 inputs include quoted market prices in active markets for similar assets or liabilities, quoted market prices in markets that are not active for identical or similar assets or liabilities and other observable inputs. Level 3 – Fair value is based on significant unobservable inputs. Examples of valuation methodologies that would result in Level 3 classification include option pricing models, discounted cash flows and other similar techniques. The Corporation monitors and evaluates available data relating to fair value measurements on an ongoing basis and recognizes transfers among the levels of the fair value hierarchy as of the date of an event or change in circumstances that affects the valuation method chosen. Examples of such changes may include the market for a particular asset or liability becoming active or inactive, changes in the availability of quoted prices, or changes in the availability of other market data. 26 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q At March 31, 2024 and December 31, 2023, assets and liabilities measured at fair value and the valuation methods used are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2024 ​ ​ Quoted Prices ​ Other Observable ​ Unobservable ​ ​ ​ ​ in Active Markets ​ Inputs ​ Inputs ​ Total (In Thousands) ​ (Level 1) ​ (Level 2) ​ (Level 3) ​ Fair Value Recurring fair value measurements, assets: ​ ​ ​ ​ AVAILABLE-FOR-SALE DEBT SECURITIES: ​ ​ ​ ​ Obligations of the U.S. Treasury ​ $ 10,231 ​ $ 0 ​ $ 0 ​ $ 10,231 Obligations of U.S. Government agencies ​ ​ 0 ​ ​ 9,376 ​ ​ 0 ​ ​ 9,376 Bank holding company debt securities ​ ​ 0 ​ ​ 23,469 ​ ​ 0 ​ ​ 23,469 Obligations of states and political subdivisions: ​ ​ ​ ​ ​ ​ Tax-exempt ​ 0 ​ 102,826 ​ 0 ​ 102,826 Taxable ​ 0 ​ 49,255 ​ 0 ​ 49,255 Mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored agencies: ​ ​ ​ ​ ​ Residential pass-through securities ​ 0 ​ 91,116 ​ 0 ​ 91,116 Residential collateralized mortgage obligations ​ 0 ​ 44,501 ​ 0 ​ 44,501 Commercial mortgage-backed securities ​ 0 ​ 66,121 ​ 0 ​ 66,121 Private label commercial mortgage-backed securities ​ 0 ​ 8,199 ​ 0 ​ 8,199 Total available-for-sale debt securities ​ 10,231 ​ 394,863 ​ 0 ​ 405,094 Marketable equity security ​ 862 ​ 0 ​ 0 ​ 862 Servicing rights ​ 0 ​ 0 ​ 2,731 ​ 2,731 RPA Out ​ ​ 0 ​ ​ 5 ​ ​ 0 ​ ​ 5 Interest rate swap agreements, assets ​ ​ 0 ​ ​ 3,222 ​ ​ 0 ​ ​ 3,222 Total recurring fair value measurements, assets ​ $ 11,093 ​ $ 398,090 ​ $ 2,731 ​ $ 411,914 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Recurring fair value measurements, liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ RPA In ​ $ 0 ​ $ 5 ​ $ 0 ​ $ 5 Interest rate swap agreements, liabilities ​ ​ 0 ​ ​ 3,222 ​ ​ 0 ​ ​ 3,222 Total recurring fair value measurements, liabilities ​ $ 0 ​ $ 3,227 ​ $ 0 ​ $ 3,227 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nonrecurring fair value measurements, assets: ​ ​ ​ ​ Loans individually evaluated for credit loss, net ​ $ 0 ​ $ 0 ​ $ 8,659 ​ $ 8,659 Foreclosed assets held for sale ​ 0 ​ 0 ​ 456 ​ 456 Total nonrecurring fair value measurements, assets ​ $ 0 ​ $ 0 ​ $ 9,115 ​ $ 9,115 ​ 27 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ Quoted Prices ​ Other Observable ​ Unobservable ​ ​ ​ ​ in Active Markets ​ Inputs ​ Inputs ​ Total (In Thousands) ​ (Level 1) ​ (Level 2) ​ (Level 3) ​ Fair Value Recurring fair value measurements, assets: ​ ​ ​ ​ AVAILABLE-FOR-SALE DEBT SECURITIES: ​ ​ ​ ​ Obligations of the U.S. Treasury ​ $ 11,290 ​ $ 0 ​ $ 0 ​ $ 11,290 Obligations of U.S. Government agencies ​ ​ 0 ​ ​ 9,946 ​ ​ 0 ​ ​ 9,946 Bank holding company debt securities ​ ​ 0 ​ ​ 23,500 ​ ​ 0 ​ ​ 23,500 Obligations of states and political subdivisions: ​ ​ ​ ​ ​ ​ Tax-exempt ​ 0 ​ 104,199 ​ 0 ​ 104,199 Taxable ​ 0 ​ 50,111 ​ 0 ​ 50,111 Mortgage-backed securities issued or guaranteed by U.S. Government agencies or sponsored agencies: ​ ​ ​ ​ Residential pass-through securities ​ 0 ​ 95,405 ​ 0 ​ 95,405 Residential collateralized mortgage obligations ​ 0 ​ 46,462 ​ 0 ​ 46,462 Commercial mortgage-backed securities ​ 0 ​ 66,682 ​ 0 ​ 66,682 Private label commercial mortgage-backed securities ​ 0 ​ 8,160 ​ 0 ​ 8,160 Total available-for-sale debt securities ​ 11,290 ​ 404,465 ​ 0 ​ 415,755 Marketable equity security ​ 871 ​ 0 ​ 0 ​ 871 Servicing rights ​ 0 ​ 0 ​ 2,659 ​ 2,659 RPA Out ​ ​ 0 ​ ​ 11 ​ ​ 0 ​ ​ 11 Interest rate swap agreements, assets ​ ​ 0 ​ ​ 2,783 ​ ​ 0 ​ ​ 2,783 Total recurring fair value measurements, assets ​ $ 12,161 ​ $ 407,259 ​ $ 2,659 ​ $ 422,079 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Recurring fair value measurements, liabilities, ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ RPA In ​ $ 0 ​ $ 13 ​ $ 0 ​ $ 13 Interest rate swap agreements, liabilities ​ ​ 0 ​ ​ 2,783 ​ ​ 0 ​ ​ 2,783 Total recurring fair value measurements, liabilities ​ $ 0 ​ $ 2,796 ​ $ 0 ​ $ 2,796 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Nonrecurring fair value measurements, assets: ​ ​ ​ ​ Impaired loans, net ​ $ 0 ​ $ 0 ​ $ 7,043 ​ $ 7,043 Foreclosed assets held for sale ​ 0 ​ 0 ​ 478 ​ 478 Total nonrecurring fair value measurements, assets ​ $ 0 ​ $ 0 ​ $ 7,521 ​ $ 7,521 ​ Management’s evaluation and selection of valuation techniques and the unobservable inputs used in determining the fair values of assets valued using Level 3 methodologies include sensitive assumptions.

Foreclosed assets held for sale consist of real estate acquired by foreclosure. For individually evaluated loans secured by real estate and foreclosed assets held for sale, estimated fair values are determined primarily using values from third-party appraisals. Appraised values are discounted to arrive at the estimated selling price of the collateral, which is considered to be the estimated fair value. The discounts also include estimated costs to sell the property.

In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Certain financial instruments and all nonfinancial instruments are excluded from disclosure requirements. Therefore, the aggregate fair value amounts presented may not represent the underlying fair value of the Corporation. 30 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q The estimated fair values, and related carrying amounts, of the Corporation’s financial instruments that are not recorded at fair value are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (In Thousands) ​ Fair Value ​ March 31, 2024 ​ December 31, 2023 ​ ​ Hierarchy ​ Carrying ​ Fair ​ Carrying ​ Fair ​ Level Amount Value Amount Value Financial assets: ​ ​ ​ ​ Cash and cash equivalents Level 1 ​ $ 42,348 ​ $ 42,348 ​ $ 52,778 ​ $ 52,778 Certificates of deposit Level 2 ​ 4,100 ​ 3,896 ​ 4,100 ​ 3,859 Restricted equity securities (included in other assets) Level 2 ​ 22,782 ​ 22,782 ​ 21,716 ​ 21,716 Loans, net Level 3 ​ 1,852,426 ​ 1,766,292 ​ 1,828,931 ​ 1,750,336 Accrued interest receivable Level 2 ​ 9,465 ​ 9,465 ​ 9,140 ​ 9,140 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial liabilities: ​ ​ ​ ​ ​ ​ Deposits with no stated maturity Level 2 ​ 1,563,605 ​ 1,563,605 ​ 1,590,357 ​ 1,590,357 Time deposits Level 2 ​ 432,298 ​ 430,309 ​ 424,449 ​ 423,643 Short-term borrowings Level 2 ​ 48,831 ​ ​ 48,831 ​ 33,874 ​ 33,874 Long-term borrowings Level 2 ​ 148,824 ​ 148,009 ​ 138,337 ​ 137,775 Senior debt ​ Level 2 ​ ​ 14,848 ​ ​ 13,455 ​ ​ 14,831 ​ ​ 12,706 Subordinated debt ​ Level 2 ​ ​ 24,745 ​ ​ 22,373 ​ ​ 24,717 ​ ​ 22,750 Accrued interest payable Level 2 ​ 2,124 ​ 2,124 ​ 1,525 ​ 1,525 ​ ​ ​ ​ ​ 31 Table of Contents CITIZENS & NORTHERN CORPORATION – FORM 10-Q
