RECENT ACCOUNTING PRONOUNCEMENTS

The Financial Accounting Standards Board (FASB) issues Accounting Standard Updates (ASUs) to communicate changes to the FASB Accounting Standards 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 consolidated financial statements issued in the foreseeable future.

Recently Issued but Not Yet Effective Accounting Pronouncements

In December of 2024, the FASB issued ASU 2024-03,*Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40),*which requires disclosure of certain costs and expenses in the notes to the consolidated financial statements. The amendments in this ASU will become effective for fiscal years beginning after December 15, 2026, and will be effective for interim periods with fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments will be applied prospectively with the option for retrospective application. We are currently evaluating the impact of the standard to our consolidated financial statement disclosures.

2. 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. The Susquehanna acquisition has contributed significantly to growth in the size of the Corporation’s balance sheet and in net interest income, noninterest income and noninterest expenses.

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 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 wereno adjustments to the fair value measurements of assets acquired or liabilities assumed in the nine months ended September 30, 2026.

Merger-related expenses related to the acquisition of Susquehanna totaled $882,000 in the third quarter 2025 and $1,049,000 in the nine months ended September 30, 2025. There wereno merger-related expenses in the nine months ended September 30, 2026.

3. PER SHARE DATA

Earnings per common share are calculated using the two-class method to determine income attributable to common shareholders. Included in the three month and nine months ended September 30, 2025 were unvested restricted stock awards that contain nonforfeitable rights to dividends that were 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. The Corporation’s basic and diluted earnings per share are the same because there areno potential dilutive shares of common stock outstanding.

4. COMPREHENSIVE INCOME

Comprehensive income is the total of (1) net income, and (2) all other changes in equity from non-stockholder sources, which are referred to as other comprehensive income (loss). The components of other comprehensive income (loss), and the related tax effects, were as follows:

The amounts shown in the table immediately above are included in the following line items in the consolidated statements of income:

Changes in the components of accumulated other comprehensive (loss) income were as follows and are presented net of tax:

5. CASH AND DUE FROM BANKS

Cash and due from banks at September 30, 2026 and December 31, 2025 include the following:

Certificates of deposit are issues by U.S. banks with original maturities greater than three months. Each certificate of deposit is fully FDIC-insured. The Corporation maintains cash and cash equivalents with certain financial institutions in excess of the FDIC insurance limit.

6. SECURITIES

Amortized cost and fair value of available-for-sale debt securities at September 30, 2026 and December 31, 2025 are summarized as follows.

The following table presents gross unrealized losses and fair value of available-for-sale debt securities with unrealized loss positions aggregated by length of time that individual securities have been in a continuous unrealized loss position at September 30, 2026 and December 31, 2025 for which an allowance for credit losses has not been recorded:

As reflected in the tables above, gross unrealized holding losses on available-for-sale debt securities totaled $50,244,000 at September 30, 2026 and $30,835,000 at December 31, 2025. At September 30, 2026, the Corporation did 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 increases in market interest rates that have occurred subsequent to the purchase of most of the securities.

At September 30, 2026 and December 31, 2025, 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 September 30, 2026 and December 31, 2025, all of the Corporation’s holdings of bank holding company debt securities, obligations of states and political subdivisions, private label commercial mortgage-backed securities and collateralized loan obligations were investment grade and there have beenno payment defaults.

Based on the results of the assessment, there wasno ACL required on available-for-sale debt securities in an unrealized loss position at September 30, 2026 and December 31, 2025.

There wereno sales of available-for-sale debt securities in the three-month and nine-month periods ended September 30, 2026 and 2025. Gross realized gains and losses from the call of available-for-sale debt securities for the three and nine months ended September 30, 2026 and 2025 were as follows:

The amortized cost and fair value of available-for-sale debt securities by contractual maturity are shown in the following table as of September 30, 2026. Actual maturities may differ from contractual maturities because counterparties may have the right to call or prepay obligations with or without call or prepayment penalties.

The Corporation’s mortgage-backed securities, collateralized mortgage obligations and asset-backed securities have stated maturities that may differ from actual maturities due to borrowers’ ability to prepay obligations. 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, collateralized mortgage obligations and asset-backed securities are shown in one period.

Investment securities carried at $203,589,000 at September 30, 2026 and $215,252,000 at December 31, 2025 were pledged as collateral for public deposits, trusts and certain other deposits as provided by law. See Note 9 for information concerning securities pledged to secure borrowing arrangements.

7. LOANS AND ALLOWANCE FOR CREDIT LOSSES

Loans receivable at September 30, 2026 and December 31, 2025 are summarized as follows:

Summary of Loans by Type

(In Thousands)

In the table above, outstanding loan balances are presented net of deferred loan origination fees of $4,127,000 at September 30, 2026 and $4,074,000 at December 31, 2025.

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.

The following tables present an analysis of past due loans as of September 30, 2026 and December 31, 2025:

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. Loans not classified are included in the “Pass” rows in the table that follows.

The following table presents the amortized cost of loans by credit quality indicators by year of origination as of September 30, 2026 and gross charge-offs for the nine months ended September 30, 2026:

The following table presents the amortized cost of loans by credit quality indicators by year of origination as of December 31, 2025 and gross charge-offs for the year ended December 31, 2025:

The following tables are a summary of the Corporation’s nonaccrual loans by major categories for the periods indicated.

The Corporation recognized interest income on nonaccrual loans of $177,000 and $734,000 in the three and nine-month periods ended September 30, 2026, respectively and $203,000 and $660,000 in the three and nine-month periods ended September 30, 2025, respectively.

The following table represents the accrued interest receivable written off by reversing interest income during the three-and nine month periods ended September 30, 2026 and 2025:

The Corporation has certain loans for which repayment is dependent upon the operation or sale of collateral, as the borrower is experiencing financial difficulty. The underlying collateral can vary based upon the type of loan. The following discussion provides more detail about the types of collateral that secure collateral dependent loans:

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 allocated to these loans:

Allowance for Credit Losses

The allowance for credit losses (“ACL”) on loans represents management’s estimate of lifetime credit losses inherent in loans as of the consolidated balance sheet date. The ACL on loans includestwo primary components: (i) an allowance established on loans which share similar risk characteristics which are collectively evaluated for credit losses, 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.

Management determines the ACL on loans that are collectively evaluated by considering the following: (a) the weighted-average remaining maturity (WARM) method is used to estimate credit losses, based on the Corporation’s historical loss experience, for pools of loans with similar risk and cash flow characteristics; (b) subjective adjustments are made, generally increasing the ACL, for qualitative risk factors that are deemed likely to cause estimated credit losses to differ from historical experience; and (c) an additional adjustment to expected credit losses is made, based on an economic forecast, and applied for the firsttwo years of the weighted-average remaining life of the portfolio.

The ACL is adjusted by qualitative factors to capture current economic conditions and risk characteristics not fully reflected in historical data. At 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 applied these refinements again in determining the ACL at September 30, 2026 and believes these refinements result in an improved estimate of the impact on the ACL of recent trends in the external data. At September 30, 2026, the Corporation implemented a refinement to the qualitative factors scale framework for determining estimated aggregate maximum loss rates. Management believes this refinement resulted in an improved estimation process.

The following table summarizes the activity related to the ACL for the three-month and nine-month periods ended September 30, 2026 and 2025.

In the three-month period ended September 30, 2026, the credit for credit losses on loans was $3,228,000. The credit for credit losses included the impact of a reduction in the ACL resulting from changes in qualitative factors based on external data used to assess trends in regional economic conditions and commercial real estate values and a reduction in loans receivable.

The provision for credit losses on loans was $8,712,000 for the nine months ended September 30, 2026 as compared to $4,172,000 for the nine months ended September 30, 2025. The increase in provision in the nine months ended September 30, 2026 was driven by the impact on the ACL of an elevated level of net charge-offs and was partially offset by net decreases in the ACL related to changes in qualitative factors and a reduction in loans receivable. The reduction in the ACL related to qualitative factors included the net impact of changes in external data referred to above, as well as changes in other factors included in management’s estimate at September 30, 2026 as compared to December 31, 2025.

The significant increase in charge-offs for the nine months ended September 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 loan is secured by a first lien on the leasehold interests of an approximately 190,000 square foot Class A office property with multiple buildings and tenants, located in Bucks County, PA. 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 in nonaccrual status as of March 31, 2026. It remains in nonaccrual status as of September 30, 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 the recording of a charge-off of $10,056,000 in the first quarter 2026. In the third quarter 2026, the Corporation recorded an additional charge-off of $352,000 related to this loan. The additional charge-off resulted from advances made to cover borrower expenses in order to protect the Corporation’s interest in the collateral. At September 30, 2026, the amortized cost basis of the loan, net of the partial charge-off, was $5,836,000.

The ACL on loans individually evaluated decreased to $2,636,000 at September 30, 2026 from $2,772,000 at December 31, 2025, including an ACL of $2,414,000 at September 30, 2026 on acquired PCD loans as part of the Susquehanna acquisition.

The ACL on loans collectively evaluated was $26,316,000 at September 30, 2026, down from $29,947,000 at June 30, 2026 and $28,276,000 at December 31, 2025. Changes in the collectively evaluated portion of the ACL at September 30, 2026 as compared to June 30, 2026 and December 31, 2025, included net decreases related to changes in qualitative adjustments and the economic forecast and the impact of changes in the WARM method estimate based on the Corporation’s net charge-off experience.

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 ACL because of the measurement methodologies used to estimate the allowance, a change to the ACL is generally not recorded upon modification. During the three and nine months ended September 30, 2026 and 2025, the Corporation madeno modifications of loans to borrowers experiencing financial difficulty.

The following table presents the performance of such loans that were modified in the twelve-month period preceding September 30, 2025:

During the nine months ended September 30, 2026, a loan secured by non-owner occupied real estate with an amortized cost basis of $1,717,000 included in the table above was paid off by the borrower through third-party financing. The Corporation recorded a $675,000 recovery upon repayment of this loan.

The Corporation had no commitments to lend any additional funds on modified loans at September 30, 2026 and 2025. The Corporation hadno loans that defaulted during the three and nine months ended September 30, 2026 and 2025 that had been modified preceding the payment default when the borrower was experiencing financial difficulty at the time of modification.

The carrying amount of foreclosed residential real estate properties held as a result of obtaining physical possession (included in foreclosed assets held for sale in the unaudited consolidated balance sheets) is as follows:

The amortized cost of consumer mortgage loans secured by residential real properties for which formal foreclosure proceedings were in process is as follows:

The Corporation is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financial needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. The contract amounts of these financial instruments at September 30, 2026 and December 31, 2025 were as follows:

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 through the (credit) provision for credit losses. 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 ACL for off-balance sheet exposures of $902,000 at September 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 following table presents the balance and activity in the ACL for off-balance sheet exposures for the three and nine months ended September 30, 2026 and 2025:

8. GOODWILL AND CORE DEPOSIT INTANGIBLES, NET

Goodwill represents the excess of the cost of acquisitions over the fair value of the net assets acquired. At September 30, 2026 and December 31, 2025, the net carrying value of goodwill was $63,311,000. There wereno changes in the carrying value of goodwill in the nine-month periods ended September 30, 2026 and 2025.

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 $126,726,000 at September 30, 2026 and $136,776,000 at December 31, 2025. There wereno interest rate swaps originated in the nine-month period ended September 30, 2026. The Corporation originatedone interest rate swap with a notional amount of $1,800,000 in the nine-month period ended September 30, 2025. Fee income on the interest swap originated in the nine-month period ended September 30, 2025 of $24,000 was included in other noninterest income in the consolidated statements of income. There wereno gross amounts of interest rate swap-related assets and liabilities not offset in the consolidated balance sheets at September 30, 2026 and December 31, 2025.

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.” There was an increase of $1,000 included in other income from RPAs in the third quarter of 2026 and $3,000 in the nine-month period ended September 30, 2026. There was an increase of $1,000 included in other noninterest income from RPAs in the third quarter 2025 and $10,000 in the nine-month period ended September 30, 2025.

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 September 30, 2026 and December 31, 2025:

The Corporation’s agreements with its derivative counterparties provide that, if the Corporation defaults on any of its indebtedness, including default where repayment of the indebtedness has not been accelerated by the lender, then the Corporation could also be declared in default on its derivative obligations. 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 $810,000 at September 30, 2026 and $1,400,000 at December 31, 2025.

13. 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.

At September 30, 2026 and December 31, 2025, assets and liabilities measured at fair value and the valuation methods used were as follows:

Level 2 valuation techniques used to measure fair value for the financial instruments in the preceding tables are as follows:

Available-for-sale debt securities - Level 2 debt securities are valued by a third-party pricing service. The pricing service uses pricing models that vary based on asset class and incorporate available market information, including quoted prices of investment securities with similar characteristics. Because many fixed income securities do not trade on a daily basis, pricing models use available information, as applicable, through processes such as benchmark yield curves, benchmarking of like securities, sector groupings and matrix pricing.

Derivative instruments - Interest rate SWAP agreements, RPA Out and RPA In- The fair value of derivatives are based on valuation models using observable market data as of the measurement date, valued by a third-party pricing service using quantitative models that utilize multiple market inputs. The inputs include prices and indices to generate continuous yield or pricing curves, estimates of current and potential future credit exposure and calculated discounted cash flow factors to value the position. The majority of market inputs are actively quoted and can be validated through external sources, including brokers, market transactions and third-party pricing services.

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. Other market participants might use substantially different assumptions, which could result in calculations of fair values that would be substantially different than the amount calculated by management.

At September 30, 2026 and December 31, 2025, quantitative information regarding valuation techniques and the significant unobservable inputs used for assets measured on a recurring basis using unobservable inputs (Level 3 methodologies) was as follows:

The fair value of servicing rights is affected by expected future interest rates. Increases (decreases) in future expected interest rates tend to increase (decrease) the fair value of the Corporation’s servicing rights because of changes in expected prepayment behavior by the borrowers on the underlying loans.

Following is a reconciliation of activity for Level 3 assets measured at fair value on a recurring basis:

Loans are individually evaluated for credit loss when they do not share similar risk characteristics as similar loans within its loan pool. 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. The estimated fair value determined for individually evaluated loans secured by real estate and foreclosed assets held for sale used unobservable inputs (Level 3 methodologies).

At September 30, 2026 and December 31, 2025, quantitative information regarding valuation techniques and the significant unobservable inputs used for nonrecurring fair value measurements using Level 3 methodologies was as follows:

Certain of the Corporation’s financial instruments are not measured at fair value in the consolidated financial statements. 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.

The estimated fair values, and related carrying amounts, of the Corporation’s financial instruments that are not recorded at fair value were as follows:

14. SEGMENT REPORTING

The Corporation’sone reportable segment is determined by the President and Chief Executive Officer, who is the designated chief operating decision maker, based upon information provided about the Corporation’s products and services offered, primarily community banking operations. The chief operating decision maker uses consolidated net income to assess performance by comparing it to and monitoring it against budget and prior year results. In addition, the chief operating decision maker uses the consolidated net income to benchmark the Corporation against its competitors. This information is used to manage resources to drive business and net earnings growth, including investment in key strategic priorities, as well as determine the Corporation’s ability to return capital to shareholders. Loans, investments, deposits and assets held in a fiduciary or custodial capacity provide the revenues in the banking operation. Interest expense, (credit) provisions for credit losses, and payroll provide the significant expenses in the banking operation. All operations are domestic.

Segment performance is evaluated using consolidated net income.
