Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	(1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations Financial Institutions, Inc. (the “Company”) is a financial holding company organized in 1931 under the laws of New York State (“New York”). The Company provides diversified financial services through its subsidiaries, Five Star Bank (the “Bank”) and Courier Capital, LLC (“Courier Capital”). The Company offers a broad array of deposit, lending and other financial services to individuals, municipalities and businesses in Western and Central New York through its wholly owned New York chartered banking subsidiary, the Bank. The Bank also has commercial loan production offices in Ellicott City (Baltimore), Maryland and Syracuse, New York, and indirect lending network relationships with franchised automobile dealers in the Capital District of New York. Effective January 1, 2024, the Company exited the Pennsylvania automobile market to align our focus more fully around its core Upstate New York market. The Company’s Banking-as-a-Service (“BaaS”) business offers banking capabilities to non-bank financial service providers and other financial technology firms (“FinTechs”), allowing them to provide banking services to their end users. These BaaS partnerships allow the Bank to offer banking services and products beyond our traditional footprint. As of March 31, 2024, the Company’s fee-based subsidiaries included SDN Insurance Agency, LLC (“SDN”), which provided a broad range of insurance services to personal and business clients, and C ourier Capital, which provides customized investment management, investment consulting and retirement plan services to individuals, businesses, institutions, foundations and retirement plans. On April 1, 2024, the Company announced and closed the sale of the assets of SDN to NFP Property & Casualty Services, Inc., a subsidiary of NFP Corp. Basis of Presentation The consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. The accounting and reporting policies conform to U.S. generally accepted accounting principles (“GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in conformity with GAAP have been condensed or omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all adjustments of a normal and recurring nature necessary for a fair presentation of the consolidated statements of financial condition, income, comprehensive income, changes in shareholders’ equity and cash flows for the periods indicated and contain adequate disclosures to make the information presented not misleading. These consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 . The results of operations for any interim periods are not necessarily indicative of the results which may be expected for the entire year or any other period. Reclassifications Certain reclassifications of previously reported amounts have been made to conform to the current year’s presentation. Such reclassifications did not impact net income or shareholders’ equity as previously reported. Use of Estimates The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates relate to the determination of the allowance for credit losses, the carrying value of goodwill and deferred tax assets, and assumptions used in the defined benefit pension plan accounting. Cash Flow Reporting Supplemental cash flow information is summarized as follows for the three months ended March 31, 2024 and 2023 (in thousands): 2024 2023 Supplemental information: Cash paid for interest $ 46,143 $ 28,666 Cash paid for income taxes — 1,134 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans 142 101 Accrued and declared unpaid dividends 4,985 4,976 (1.) BASIS OF PRESENTATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued) Fraudulent Activity In early March 2024, the Company discovered fraudulent activity associated with deposit transactions conducted over the course of several business days by an in-market business customer of the Bank, which resulted in an $ 18.4 million pre-tax loss. T he Bank is working with the appropriate law enforcement authorities in connection with this matter and is pursuing all legal recourse available to recover additional funds and minimize the loss. However, there can be no assurance that the Company will be able to recover any further offset to the deposit loss. The ultimate financial impact could be lower and will depend, in part, on the Bank’s success in its efforts to recover the funds. The fraud exposure arose from non-contractual, external fraud, and was treated as an operational loss, recorded in deposit-related charged-off items, in noninterest expense for the first quarter of 2024 . Recent Accounting Pronouncements In March 2023, the FASB issued ASU No. 2023-02, Investments — Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. The ASU allows for entities to consistently account for tax credit equity investments utilizing the proportional amortization method across all types of tax credits when certain requirements are met. The election of proportional amortization method must be made on a programmatic basis rather than an individual investment basis. For previously held tax credit investments, the amendments will be applied either on a modified retrospective basis or a retrospective basis. The amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. Standards Not Yet Effective In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments expand the disclosure requirements of segment expenses, as well as adding disclosure of the title and position of the chief operation decision maker “CODM” and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources is also required. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The adoption of this guidance may require additional disclosure in the Company’s financial statement related to segments. In December 2023, the FASB issued ASU 2023-09, Income Tax (Topic 740): Improvements to Income Tax Disclosures. The amendments expand the disclosure requirements of income taxes, primarily related to the income tax rate reconciliation and income taxes paid. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred income tax liabilities. The amendments are effective for fiscal years beginning after December 15, 2024, and interim periods within fiscal years beginning after December 15, 2025. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.

For held to maturity (“HTM”) debt securities, AIR totaled $ 783 thousand and $ 571 thousand as of March 31, 2024 and December 31, 2023, respectively. AIR is included in other assets on the Company’s consolidated statements of financial condition.

INVESTMENT SECURITIES (Continued) The total number of AFS securities positions in the investment portfolio in an unrealized loss position was 201 at both March 31, 2024 and December 31, 2023. At March 31, 2024 , the Company had positions in 197 investment securities with a fair value of $ 809.5 million and a total unrealized loss of $ 160.8 million that had been in a continuous unrealized loss position for more than 12 months. At March 31, 2024 , there were a total of four securities positions in the Company’s investment portfolio with a fair value of $ 64.7 million and a total unrealized loss of $ 1 thousand that had been in a continuous unrealized loss position for less than 12 months. At December 31, 2023 , the Company had a position in 198 investment securities with a fair value of $ 835.5 million and a total unrealized loss of $ 151.5 million that had been in a continuous unrealized loss position for more than 12 months. At December 31, 2023 , there were a total of three securities positions in the Company’s investment portfolio with a fair value of $ 8 thousand and a total unrealized loss of less than $ 1 thousand that had been in a continuous unrealized loss position for less than 12 months. The unrealized loss on investment securities was predominantly caused by changes in market interest rates subsequent to purchase. The fair value of the Company’s portfolio fluctuates as market interest rates change. Securities Available for Sale As of March 31, 2024 and December 31, 2023 , no al lowance for credit losses had been recognized on AFS securities in an unrealized loss position as management does not believe any of the securities were impaired due to reasons of credit quality. This is based upon our analysis of the underlying risk characteristics, including credit ratings, and other qualitative factors related to our available for sale securities and in consideration of our historical credit loss experience and internal forecasts. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, the Company expects to recover the amortized cost basis of its investments and more than likely will not need to sell before the recovery period for operating purposes, with no impairment identified. As the portfolio is managed from a liquidity, earnings, and risk standpoint, sales from the AFS portfolio may be warranted based upon prevailing market factors. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying securities were purchased. The fair value is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. Securities Held to Maturity The Company’s HTM investment securities include debt securities that are issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. In addition, the Company’s HTM investment securities include debt securities that are issued by state and local government agencies, or municipal bonds. The Company monitors the credit quality of our municipal bonds through the use of a credit rating agency or by ratings that are derived by an internal scoring model. The scoring methodology for the internally derived ratings is based on a series of financial ratios for the municipality being reviewed as compared to typical industry figures. This information is used to determine the financial strengths and weaknesses of the municipality, which is indicated with a numeric rating. This number is then converted into a letter rating to better match the system used by the credit rating agencies. As of March 31, 2024 , $ 62.3 million of our municipal bonds were rated as an equivalent to Standard & Poor’s A/AA/AAA, with $ 4.1 million internally rated to be the equivalent of Standard & Poor’s A/AA/AAA rating. Additionally, no municipal bonds were rated below investment grade. As of December 31, 2023 , $ 64.6 million of our municipal bonds were rated as an equivalent to Standard & Poor’s A/AA/AAA, with $ 4.2 million internally rated to be the equivalent of Standard & Poor’s A/AA/AAA rating, and no municipal bonds were rated below investment grade. As of March 31, 2024 and December 31, 2023 , the Company had no past due or nonaccrual held to maturity investment securities.

Consumer overdrafts are overdrawn deposit accounts which have been reclassified as loans but by their terms do not accrue interest. Interest income on nonaccrual loans, if recognized, is recorded using the cash basis method of accounting. There was no interest income recognized on nonaccrual loans during the three months ended March 31, 2024 and 2023. Estimated interest income of $ 132 thousand and $ 122 thousand for the three months ended March 31, 2024 and 2023, respectively, would have been recorded if all such loans had been accruing interest according to their original contractual terms. Loan Modifications for Borrower Experiencing Financial Difficulty Loans may be modified when it is determined that a borrower is experiencing financial difficulty. Loan modifications may include principal forgiveness, interest rate reduction, an other-than-insignificant payment delay, and term extensions, or a combination of these concessions. The following table presents the amortized cost basis of loans modified to borrowers experiencing financial difficulty, disaggregated by loan class and type of concession granted as of March 31, 2024 (in thousands): Term Extension Amortized Cost Basis % of Total Loans Loan Type Commercial business $ — 0.0 % Commercial mortgage — 0.0 % Residential real estate loans 1,506 0.2 % Residential real estate lines — 0.0 % Consumer indirect — 0.0 % Other consumer — 0.0 % Total $ 1,506 0.0 % The following table describes the financial effect of the modifications made to borrowers experiencing financial difficulty: Term Extension Loan Type Financial Effect Residential real estate loans Added a weighted average 10.0 years to the life of the loans, which reduced monthly payment amount for the borrower.

LOANS (Continued) The Company closely monitors the performance of loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following table depicts the performance of loans that have been modified in the three months ended March 31, 2024 (in thousands): Payment Status (Amortized Cost Basis) Current 30-89 Days 90+ Days Loan Type Commercial business $ - $ - $ - Commercial mortgage - - - Residential real estate loans 865 144 97 Residential real estate lines - - - Consumer indirect - - - Other consumer - - - Total $ 865 $ 144 $ 97 Collateral Dependent Loans Management has determined that specific commercial loans on nonaccrual status, all loans that have had their terms restructured when a borrower is experiencing financial difficulty, and other loans deemed appropriate by management where repayment is expected to be provided substantially through the operation or sale of the collateral to be collateral dependent loans. The following table presents the amortized cost basis of collateral dependent loans by collateral type as of March 31, 2024 and December 31, 2023 (in thousands): Collateral type Business assets Real property Total Specific Reserve March 31, 2024 Commercial business $ 7,260 $ 5,000 $ 12,260 $ 2,314 Commercial mortgage — 20,808 20,808 — Total $ 7,260 $ 25,808 $ 33,068 $ 2,314 December 31, 2023 Commercial business $ 8,698 $ 5,000 $ 13,698 $ 2,198 Commercial mortgage — 26,575 26,575 559 Total $ 8,698 $ 31,575 $ 40,273 $ 2,757 Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors such as the fair value of collateral. The Company analyzes commercial business and commercial mortgage loans individually by classifying the loans as to credit risk. Risk ratings are updated any time the situation warrants. The Company uses the following definitions for risk ratings: Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date. Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans that do not meet the criteria above that are analyzed individually as part of the process described above are considered “uncriticized” or pass-rated loans and are included in groups of homogeneous loans with similar risk and loss characteristics.

LOANS (Continued) Risk Characteristics Commercial business loans primarily consist of loans to small to mid-sized businesses in our market area in a diverse range of industries. These loans are typically associated with higher credit risk and typically are made on the basis of the borrower’s ability to make repayment from the cash flow of the borrower’s business. Further, the collateral securing the loans may depreciate over time, may be difficult to appraise and may fluctuate in value. The credit risk related to commercial loans is largely influenced by general economic conditions, including inflation, and the resulting impact on a borrower’s operations or on the value of underlying collateral, if any. Commercial mortgage loans generally have larger balances and involve a greater degree of risk than residential mortgage loans, potentially resulting in higher losses on an individual customer basis. Loan repayment is often dependent on the successful operation and management of the properties, as well as on the collateral securing the loan. Economic events, including inflation, influencing the ability of the tenants to pay rent at these properties, or conditions in the real estate market could have an adverse impact on the cash flows generated by properties securing the Company’s commercial real estate loans and on the value of such properties. Residential real estate loans (comprised of conventional mortgages and home equity loans) and residential real estate lines of credit (comprised of home equity lines of credit) are generally made based on the borrower’s ability to make repayment from his or her employment and other income but are secured by real property whose value tends to be more easily ascertainable. Credit risk for these types of loans is generally influenced by general economic conditions, the characteristics of individual borrowers, and the nature of the loan collateral. Consumer indirect and other consumer loans may entail greater credit risk than residential mortgage loans and home equities, particularly in the case of other consumer loans which are primarily unsecured or, in the case of some BaaS loans, secured by depreciable assets such as solar panels, and in the case of indirect consumer loans, secured by depreciable assets such as automobiles. In such cases, any repossessed collateral for a defaulted consumer loan may not provide an adequate source of repayment of the outstanding loan balance. In addition, consumer loan collections are dependent on the borrower’s continuing financial stability, and thus are more likely to be affected by inflation and adverse personal circumstances such as job loss, illness or personal bankruptcy, including the heightened risk that such circumstances may arise as a result of inflation. Furthermore, the application of v arious federal and state laws, including bankruptcy and insolvency laws, may limit the amount which can be recovered on such loans.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instrument and Hedging Activities	(8.) DERIVATIVE INSTRUMENT AND HEDGING ACTIVITIES Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities, and the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments. Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company uses interest rate caps and interest rate swaps as part of its interest rate risk management strategy. Interest rate caps designated as cash flow hedges involve the receipt of variable amounts from a counterparty if interest rates rise above the strike rate on the contract in exchange for an up-front premium. Such derivatives were used to hedge the variable cash flows associated with short-term borrowings or brokered CDs. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. The following table summarizes the terms of the Company’s outstanding interest rate swap agreements entered into to manage its exposure to the variability in future cash flows at March 31, 2024 (dollars in thousands): Effective Date Expiration Date Notional Amount Pay Fixed Rate 4/11/2022 4/11/2027 $ 50,000 0.787 % 1/24/2023 1/24/2026 $ 30,000 3.669 % 5/5/2023 5/5/2026 $ 25,000 3.4615 % For derivatives designated and that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in accumulated other comprehensive income (loss) and subsequently reclassified into interest expense in the same period(s) during which the hedged transaction affects earnings. Amounts reported in accumulated other comprehensive income (loss) related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s borrowings. During the next twelve months, the Company estimates that $ 2.9 million in accumulated other comprehensive loss related to derivatives will be reclassified as an increase to interest expense. Interest Rate Swaps The Company executes interest rate swaps with commercial banking customers to facilitate their respective risk management strategies. These interest rate swaps are simultaneously hedged by offsetting interest rate swaps that the Company executes with a third party, such that the Company minimizes its net risk exposure resulting from such transactions. As the interest rate swaps associated with this program do not meet hedge accounting requirements, changes in the fair value of both the customer swaps and the offsetting swaps are recognized directly in earnings. Credit-risk-related Contingent Features The Company has agreements with certain of its derivative counterparties that contain one or more of the following provisions: (a) if the Company defaults on any of its indebtedness, including a default where repayment of the indebtedness has not been accelerated by the lender, the Company could also be declared in default on its derivative obligations, and (b) if the Company fails to maintain its status as a well-capitalized institution, the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. (8.) DERIVATIVE INSTRUMENT AND HEDGING ACTIVITIES (Continued) Mortgage Banking Derivatives The Company extends rate lock agreements to borrowers related to the origination of residential mortgage loans. To mitigate the interest rate risk inherent in these rate lock agreements when the Company intends to sell the related loan, once originated, as well as closed residential mortgage loans held for sale, the Company enters into forward commitments to sell individual residential mortgages. Rate lock agreements and forward commitments are considered derivatives and are recorded at fair value. Fair Values of Derivative Instruments on the Balance Sheet The table below presents the notional amounts, respective fair values of the Company’s derivative financial instruments, as well as their classification on the balance sheet as of March 31, 2024 and December 31, 2023 (in thousands): Asset derivatives Liability derivatives Gross notional Fair value Fair value March 31, 2024 December 31, 2023 Balance March 31, 2024 December 31, 2023 Balance March 31, 2024 December 31, 2023 Derivatives designated as hedging instruments Cash flow hedges $ 105,000 $ 105,000 Other assets $ 6,835 $ 5,939 Other liabilities $ — $ — Total derivatives $ 105,000 $ 105,000 $ 6,835 $ 5,939 $ — $ — Derivatives not designated as hedging instruments Interest rate swaps (1) $ 1,089,166 $ 1,104,804 Other assets $ 44,173 $ 37,517 Other liabilities $ 44,175 $ 37,519 Credit contracts 75,168 81,211 Other assets — — Other liabilities — — Mortgage banking 18,149 5,292 Other assets 221 50 Other liabilities 5 2 Total derivatives $ 1,182,483 $ 1,191,307 $ 44,394 $ 37,567 $ 44,180 $ 37,521 (1) The Company was holding collateral of $ 50.2 million and $ 40.4 million against its net obligations under these contracts at March 31, 2024 and December 31, 2023 , respectively.

Share-Based Payment Arrangement, Noncash Expense [Abstract]
Share-Based Compensation Plans	(11.) SHARE-BASED COMPENSATION PLANS The Company maintains certain share-based compensation plans, approved by the Company’s shareholders, which are administered by the Management Development and Compensation Committee (the “MD&C Committee”) of the Board. The share-based compensation plans were established to allow for the granting of compensation awards to attract, motivate and retain employees, executive officers and non-employee directors who contribute to the long-term growth and profitability of the Company and to give such persons a proprietary interest in the Company, thereby enhancing their personal interest in the Company’s success. The Company awards grants of performance-based restricted stock units (“PSUs”) to certain members of management. Fifty percent of the shares subject to each grant that ultimately vest are contingent on achieving specified return on average equity (“ROAE”) targets relative to the market index the Compensation Committee has selected as a peer group for this purpose. These shares will be earned based on the Company’s achievement of a relative ROAE performance requirement, on a percentile basis, compared to the market index over a three-year performance period. The remaining fifty percent of the PSUs that ultimately vest are contingent upon achievement of an average return on average assets (“ROAA”) performance requirement over a three-year performance period. The shares earned based on the achievement of the ROAE and ROAA performance requirement, if any, will vest on March 1 of the third year from the grant date assuming the recipient’s continuous service to the Company. The Company granted restricted stock units (“RSUs”) and performance-based restricted stock units (“PSUs”) during the three months ended March 31, 2024 as follows: Number of Weighted Average Grant Date Fair Value RSUs 129,665 $ 15.58 PSUs 54,754 $ 15.59 The grant-date fair value for the RSUs and PSUs granted during the three months ended March 31, 2024 was equal to the closing market price of our common stock on the date of grant reduced by the present value of the dividends expected to be paid on the underlying shares. (11.) SHARE-BASED COMPENSATION PLANS (Continued) Assuming the recipient’s continuous service to the Company, the RSUs granted during the three months ended March 31, 2024 will vest on the third anniversary of the grant date. The Company amortizes the expense related to share-based compensation awards over the vesting period. Share-based compensation expense is recorded as a component of salaries and employee benefits in the consolidated statements of income for awards granted to management and as a component of other noninterest expense for awards granted to directors. The share-based compensation expense included in the consolidated statements of income, is as follows (in thousands): Three months ended 2024 2023 Salaries and employee benefits $ 528 $ 510 Other noninterest expense 41 41 Total share-based compensation expense $ 569 $ 551 Income tax benefit realized for compensation costs $ 286 $ 368 At March 31, 2024, there was $ 5.2 million of unrecognized compensation expense related to unvested restricted stock awards and restricted stock units that is expected to be recognized over a weighted average period of 2.36 years.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	(13.) COMMITMENTS AND CONTINGENCIES Financial Instruments with Off-Balance Sheet Risk The Company has financial instruments with off-balance sheet risk established in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk extending beyond amounts recognized in the financial statements. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is essentially the same as that involved with extending loans to customers. The Company uses the same credit underwriting policies in making commitments and conditional obligations as for on-balance sheet instruments. Off-balance sheet commitments consist of the following (in thousands): March 31, December 31, Commitments to extend credit $ 1,109,364 $ 1,200,617 Standby letters of credit 13,292 13,498 (13.) COMMITMENTS AND CONTINGENCIES (Continued) Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the agreement. Commitments generally have fixed expiration dates or other termination clauses which may require payment of a fee. Commitments may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if any, is based on management’s credit evaluation of the borrower. Standby letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party. These standby letters of credit are primarily issued to support private borrowing arrangements. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. Unfunded Commitments At March 31, 2024 and December 31, 2023, the allowance for credit losses for unfunded commitments totaled $ 3.0 million and $ 3.6 million , respectively, and was included in other liabilities on the Company’ s consolidated statements of financial condition. The credit loss expense for unfunded commitments was as follows (in thousands): Three months ended 2024 2023 Credit (benefit) loss for unfunded commitments $ ( 570 ) $ 11 Contingent Liabilities and Litigation In the ordinary course of business, there are various threatened and pending legal proceedings against the Company. Management believes that the aggregate liability, if any, arising from such litigation, except for the matter described below, would not have a material adverse effect on the Company’s consolidated financial statements. As previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 as filed with the SEC on March 13, 2024 and as disclosed in Part II, Item 1 of this Quarterly Report on Form 10-Q, the Company is party to an action filed against it on May 16, 2017 by Matthew L. Chipego, Charlene Mowry, Constance C. Churchill and Joseph W. Ewing in the Court of Common Pleas in Philadelphia, Pennsylvania. Plaintiffs sought and were granted class certification to represent classes of consumers in New York and Pennsylvania seeking to recover statutory damages, interest and declaratory relief. The plaintiffs specifically claim that the notices the Bank sent to defaulting consumers after their vehicles were repossessed did not comply with the relevant portions of the Uniform Commercial Code in New York and Pennsylvania. The Company disputes and believes it has meritorious defenses against these claims and plans to vigorously defend itself. On September 30, 2021, the Court granted plaintiffs’ motion for class certification and certified four different classes (two classes of New York consumers and two classes of Pennsylvania consumers). There are approximately 5,200 members in the New York classes and 300 members in the Pennsylvania classes. On September 26, 2022, the lower Court denied the plaintiffs’ motion for partial summary judgment for most of the relief they seek and found that there were questions of fact as to whether the members of the class had purchased the subject vehicles for “consumer use” within the meaning of the relevant statutes. The Court also denied the Company’s motion for partial summary judgment and seeking an offset in the form of recoupment reducing any liability that may be imposed against the Company by the amounts that the borrowers owe for failing to repay their motor vehicle loans, determining that the Court could not enter a judgment on recoupment – which is a set off from liability – without first determining whether there was liability. On October 7, 2022, the Superior Court of Pennsylvania granted the Company’s December 20, 2021 Request for an Interlocutory Appeal of the denial of the Company’s motion to dismiss the claims brought by New York borrowers for lack of subject matter jurisdiction and lack of standing. In a Memorandum filed on February 13, 2024, the Superior Court affirmed the decision of the lower court, holding that trial court has subject matter jurisdiction over the New York part of this action and that the New York plaintiffs have standing to pursue relief against the Company. The Superior Court also remanded the case to the lower court for further proceedings, which will include the completion of any remaining discovery and an adjudication of the open claims and defenses that have been asserted in the case. Once the lower court has issued a final adjudication, the parties will have an opportunity to appeal adverse rulings in the case. (13.) COMMITMENTS AND CONTINGENCIES (Continued) On April 5, 2024, the lower court conducted a Case Management Conference to discuss remaining matters and next steps, and thereafter issued a Scheduling Order setting a deadline of April 19, 2024 for the Company to re-file its motion to compel discovery and motion for re-consideration of the prior striking of its jurisdictional defense and scheduled a pre-trial conference for July 11, 2024. The time for the Company to re-file the aforementioned motions was extended to April 23, 2024, and the Company timely filed and served them. The case was also re-assigned to another member of the Court of Common Pleas to handle future proceedings. The Company has not accrued a contingent liability for this matter at this time because, given its defenses, it is unable to conclude whether a liability is probable to occur nor is it able to currently reasonably estimate the amount of potential loss. If the Company settles these claims or the action is not resolved in its favor, the Company may suffer reputational damage and incur legal costs, settlements or judgments that exceed the amounts covered by its insurer. The Company can provide no assurances that its insurer will cover the full legal costs, settlements or judgments it incurs. If the Company is unsuccessful in defending itself from these claims or if its insurer does not cover the full amount of legal costs it incurs, the result may materially adversely affect the Company’s business, results of operations and financial condition.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	(14.) FAIR VALUE MEASUREMENTS Determination of Fair Value – Assets Measured at Fair Value on a Recurring and Nonrecurring Basis Valuation Hierarchy The fair value of an asset or liability is the price that would be received to sell that asset or paid to transfer that liability in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. Accounting Standards Codification (“ASC”) Topic 820, “Fair Value Measurements and Disclosures,” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. There have been no changes in the valuation techniques used during the current period. The fair value hierarchy is as follows: • Level 1 - Unadjusted quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. • Level 2 - Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means. • Level 3 - Unobservable inputs for determining the fair values of assets or liabilities that reflect an entity’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. Transfers between levels of the fair value hierarchy are recorded as of the end of the reporting period. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Securities available for sale: Securities classified as available for sale are reported at fair value utilizing Level 2 inputs. The Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Derivative instruments: The fair value of derivative instruments is determined using quoted secondary market prices for similar financial instruments and are classified as Level 2 in the fair value hierarchy. (14.) FAIR VALUE MEASUREMENTS (Continued) Loans held for sale: The fair value of loans held for sale is determined using quoted secondary market prices and investor commitments. Loans held for sale are classified as Level 2 in the fair value hierarchy. Collateral dependent loans: Fair value of collateral dependent loans with specific allocations of the allowance for credit losses – loans is measured based on the value of the collateral securing these loans and is classified as Level 3 in the fair value hierarchy. Collateral may be real estate and/or business assets including equipment, inventory and/or accounts receivable and collateral value is determined based on appraisals performed by qualified licensed appraisers hired by the Company. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Appraised and reported values may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and the client’s business. Such discounts are typically significant and result in a Level 3 classification of the inputs for determining fair value. Collateral dependent loans are reviewed and evaluated on at least a quarterly basis for additional impairment and adjusted accordingly, based on the same factors identified above. Long-lived assets held for sale: The fair value of the long-lived assets held for sale was based on estimated market prices from independently prepared current appraisals and are classified as Level 3 in the fair value hierarchy. Loan servicing rights: Loan servicing rights do not trade in an active market with readily observable market data. As a result, the Company estimates the fair value of loan servicing rights by using a discounted cash flow model to calculate the present value of estimated future net servicing income. The assumptions used in the discounted cash flow model are those that management believes market participants would use in estimating future net servicing income, including estimates of loan prepayment rates, servicing costs, ancillary income, impound account balances, and discount rates. The significant unobservable inputs used in the fair value measurement of the Company’s loan servicing rights are the constant prepayment rates and weighted average discount rate. Significant increases (decreases) in any of those inputs in isolation could result in a significantly lower (higher) fair value measurement. Although the constant prepayment rate and the discount rate are not directly interrelated, they will generally move in opposite directions. Loan servicing rights are classified as Level 3 measurements due to the use of significant unobservable inputs, as well as significant management judgment and estimation. Other real estate owned (foreclosed assets): Nonrecurring adjustments to certain commercial and residential real estate properties classified as other real estate owned are measured at the lower of carrying amount or fair value, less costs to sell. Fair values are generally based on third party appraisals of the property, resulting in a Level 3 classification. The appraisals are sometimes further discounted based on management’s historical knowledge, changes in market conditions from the time of valuation, and/or management’s expertise and knowledge of the client and client’s business. Such discounts are typically significant and result in a Level 3 classification of the inputs for determining fair value. In cases where the carrying amount exceeds the fair value, less costs to sell, an impairment loss is recognized. Commitments to extend credit and letters of credit: Commitments to extend credit and fund letters of credit are principally at current interest rates, and, therefore, the carrying amount approximates fair value. The fair value of commitments is not material. (14.) FAIR VALUE MEASUREMENTS (Continued) Assets Measured at Fair Value The following tables present for each of the fair-value hierarchy levels the Company’s assets that are measured at fair value on a recurring and nonrecurring basis as of the dates indicated (in thousands).

FAIR VALUE MEASUREMENTS (Continued) Changes in Level 3 Fair Value Measurements There were no assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) as of or during the three months ended March 31, 2024 and 2023. Disclosures about Fair Value of Financial Instruments The assumptions used below are expected to approximate those that market participants would use in valuing these financial instruments. Fair value estimates are made at a specific point in time, based on available market information and judgments about the financial instrument, including estimates of timing, amount of expected future cash flows and the credit standing of the issuer. Such estimates do not consider the tax impact of the realization of unrealized gains or losses. In some cases, the fair value estimates cannot be substantiated by comparison to independent markets. In addition, the disclosed fair value may not be realized in the immediate settlement of the financial instrument. Care should be exercised in deriving conclusions about our business, its value or financial position based on the fair value information of financial instruments presented below. The estimated fair value approximates carrying value for cash and cash equivalents, Federal Home Loan Bank (“FHLB”) and Federal Reserve Bank (“FRB”) stock, accrued interest receivable, non-maturity deposits, short-term borrowings and accrued interest payable. Fair value estimates for other financial instruments not included elsewhere in this disclosure are discussed below. Securities held to maturity: The fair value of the Company’s investment securities held to maturity is primarily measured using information from a third-party pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Loans: The fair value of the Company’s loans was estimated by discounting the expected future cash flows using the current interest rates at which similar loans would be made for the same remaining maturities. Loans were first segregated by type, such as commercial, residential mortgage, and consumer, and were then further segmented into fixed and variable rate and loan quality categories. Expected future cash flows were projected based on contractual cash flows, adjusted for estimated prepayments. Time deposits: The fair value of time deposits was estimated using a discounted cash flow approach that applies prevailing market interest rates for similar maturity instruments. The fair values of the Company’s time deposit liabilities do not take into consideration the value of the Company’s long-term relationships with depositors, which may have significant value. Long-term borrowings: Long-term borrowings consist of $ 75 million of subordinated notes and $ 50 million of long-term borrowings from the FHLB. The subordinated notes are publicly traded and are valued based on market prices, which are characterized as Level 2 liabilities in the fair value hierarchy. The FHLB borrowings are valued using discounted cash flows based on current market rates for borrowings with similar remaining maturities and are characterized as Level 2 liabilities in the fair value hierarchy.

Segment Reporting [Abstract]
Segment Reporting	(15.) SEGMENT REPORTING The Company has one reportable segment, Banking, which includes all the Company’s retail and commercial banking operations. This reportable segment has been identified and organized based on the nature of the underlying products and services applicable to the segment, the type of customers to whom those products and services are offered and the distribution channel through which those products and services are made available. All other segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other,” which include the activities of SDN and Courier Capital. SDN is a full-service insurance agency that provided a broad range of insurance services to both personal and business clients, and Courier Capital is our investment advisor and wealth management firm that offers customized investment management, financial planning and consulting services to individuals and families, businesses, institutions, non-profits and retirement plans. Also included in “All Other” are Holding Company amounts, which are the primary differences between segment amounts and consolidated totals, along with amounts to eliminate balances and transactions between segments.

All significant intercompany accounts and transactions have been eliminated in consolidation. The accounting and reporting policies conform to U.S. generally accepted accounting principles (“GAAP”). Certain information and footnote disclosures normally included in financial statements prepared in conformity with GAAP have been condensed or omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all adjustments of a normal and recurring nature necessary for a fair presentation of the consolidated statements of financial condition, income, comprehensive income, changes in shareholders’ equity and cash flows for the periods indicated and contain adequate disclosures to make the information presented not misleading. These consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2023 . The results of operations for any interim periods are not necessarily indicative of the results which may be expected for the entire year or any other period.
Reclassifications	Reclassifications Certain reclassifications of previously reported amounts have been made to conform to the current year’s presentation. Such reclassifications did not impact net income or shareholders’ equity as previously reported.
Use of Estimates	Use of Estimates The preparation of these financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates relate to the determination of the allowance for credit losses, the carrying value of goodwill and deferred tax assets, and assumptions used in the defined benefit pension plan accounting.
Cash Flow Reporting	Cash Flow Reporting Supplemental cash flow information is summarized as follows for the three months ended March 31, 2024 and 2023 (in thousands): 2024 2023 Supplemental information: Cash paid for interest $ 46,143 $ 28,666 Cash paid for income taxes — 1,134 Noncash investing and financing activities: Real estate and other assets acquired in settlement of loans 142 101 Accrued and declared unpaid dividends 4,985 4,976
Fraudulent Activity	Fraudulent Activity In early March 2024, the Company discovered fraudulent activity associated with deposit transactions conducted over the course of several business days by an in-market business customer of the Bank, which resulted in an $ 18.4 million pre-tax loss. T he Bank is working with the appropriate law enforcement authorities in connection with this matter and is pursuing all legal recourse available to recover additional funds and minimize the loss. However, there can be no assurance that the Company will be able to recover any further offset to the deposit loss. The ultimate financial impact could be lower and will depend, in part, on the Bank’s success in its efforts to recover the funds. The fraud exposure arose from non-contractual, external fraud, and was treated as an operational loss, recorded in deposit-related charged-off items, in noninterest expense for the first quarter of 2024 .
Recent Accounting Pronouncements	Recent Accounting Pronouncements In March 2023, the FASB issued ASU No. 2023-02, Investments — Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method. The ASU allows for entities to consistently account for tax credit equity investments utilizing the proportional amortization method across all types of tax credits when certain requirements are met. The election of proportional amortization method must be made on a programmatic basis rather than an individual investment basis. For previously held tax credit investments, the amendments will be applied either on a modified retrospective basis or a retrospective basis. The amendments are effective for fiscal years beginning after December 15, 2023, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance did not have a material impact on the Company’s consolidated financial statements. Standards Not Yet Effective In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments expand the disclosure requirements of segment expenses, as well as adding disclosure of the title and position of the chief operation decision maker “CODM” and an explanation of how the CODM uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources is also required. The amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The adoption of this guidance may require additional disclosure in the Company’s financial statement related to segments. In December 2023, the FASB issued ASU 2023-09, Income Tax (Topic 740): Improvements to Income Tax Disclosures. The amendments expand the disclosure requirements of income taxes, primarily related to the income tax rate reconciliation and income taxes paid. The guidance also eliminates certain existing disclosure requirements related to uncertain tax positions and unrecognized deferred income tax liabilities. The amendments are effective for fiscal years beginning after December 15, 2024, and interim periods within fiscal years beginning after December 15, 2025. Early adoption is permitted. The adoption of this guidance is not expected to have a material impact on the Company’s consolidated financial statements.
