NOTES TO UNAUDITED CONSOLIDATED CONDENSED FINANCIAL STATEMENTS

Note 1 –Basis of Presentation

The accompanying unaudited consolidated condensed financial statements included in this report have been prepared for Park. In the opinion of management, all adjustments (consisting of normal recurring accruals) necessary for a fair presentation of the results of operations for the interim periods included herein have been made. The results of operations for the three-month and nine-month periods ended September 30, 2026 are not necessarily indicative of the operating results to be anticipated for the year ending December 31, 2026.

As detailed in Note 3, Park acquired First Citizens on February 1, 2026. As part of the acquisition, Park subsidiaries acquired 100% of the outstanding common stock and 60% of the outstanding preferred stock of First Citizens Properties, Inc. Former directors, executive officers and certain employees and affiliates of First Citizens own approximately 40% of the preferred stock of First Citizens Properties, Inc. which is reported as "Non-controlling interest in consolidated subsidiary" in the consolidated condensed balance sheets. The noncontrolling interest reflects preferred stock interests retained by legacy holders of the acquired real estate investment trust subsidiary and does not affect Park's control of the entity. Net income attributable to the non-controlling interest was $31,000 for the three months ended September 30, 2026 and was $93,000 for the nine months ended September 30, 2026.

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with the instructions for Quarterly Reports on Form 10-Q and Article 10 of Regulation S-X of the SEC. Therefore, they do not include all information and footnotes necessary for a fair presentation of the consolidated condensed balance sheets, consolidated condensed statements of income, consolidated condensed statements of comprehensive income, consolidated condensed statements of changes in equity and consolidated condensed statements of cash flows in conformity with U.S. GAAP. These financial statements should be read in conjunction with the consolidated financial statements included in Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA in Park's 2025 Form 10-K. Certain prior period amounts have been reclassified to conform to the current period presentation.

Park’s significant accounting policies are described in Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements included in Park’s 2025 Form 10-K. For interim reporting purposes, Park follows the same basic accounting policies, as updated by the information contained in this report, and considers each interim period an integral part of an annual period. The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated condensed financial statements and accompanying notes. Actual results could differ materially from those estimates.

Subsequent Events

Management evaluated subsequent events through November 5, 2026, the date the financial statements were available to be issued.

October 26, 2026, the Park Board of Directors declared a $1.10 per common share quarterly cash dividend in respect of Park's common shares and a special cash dividend of $1.30 per common share in respect of Park's common shares. The cash dividend and special cash dividend are payable on December 10, 2026 to common shareholders of record as of the close of business on November 20, 2026.

No other subsequent events occurred that require recognition or disclosure in the accompanying consolidated financial statements.

Note 2 -Adoption of New Accounting Pronouncements and Issued But Not Yet Effective Accounting Standards

The following is a summary of new accounting pronouncements impacting Park's consolidated condensed financial statements:

Adoption of New Accounting Pronouncements

ASU 2025-08 - Financial Instruments - Credit Losses (Topic 326) - Purchased Loans: In November 2025, FASB issued ASU 2025-08 - Financial Instruments - Credit Losses (Topic 326) - Purchased Loans. ASU 2025-08 expands the use of the gross-up method to certain acquired loans beyond purchased financial assets with credit deterioration ("PCD" assets). Under the gross-up method, an allowance for credit losses is recognized at the acquisition date with an offset to the asset's amortized cost basis. ASU 2025-08 does the following: (1) applies the gross-up method to acquired non-PCD assets that are purchased seasoned loans and provides criteria for determining whether acquired loans qualify as purchased seasoned loans; (2) for purchased seasoned loans, eliminates the Day 1 credit loss expense and reduces interest income recognized in subsequent periods as the gross-up method will now apply to these loans; (3) maintains the guidance for PCD assets; (4) results in narrow subsequent measurement differences between purchased seasoned loans and PCD assets.

ASU 2025-08 is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2026 and is applied on a prospective basis. Early adoption is permitted in an interim or annual reporting period in which financial statements have not yet been issued or made available for issuance. Park elected to adopt ASU 2025-08 effective January 1, 2025. The adoption of ASU 2025-08 did not have an impact on Park's existing loan portfolio or allowance for credit losses, but did impact the accounting for First Citizens purchased loans.

Issued But Not Yet Effective Accounting Standards

ASU 2023-06 - Disclosure Improvements - Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative: In October 2023, FASB issued ASU 2023-06 - Disclosure Improvements - Codification Amendments in Response to the SEC's Disclosure Update and Simplification Initiative. ASU 2023-06 amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification. ASU 2023-06 was issued in response to the SEC's August 2018 final rule that updated and simplified disclosure requirements. In the final rule, the SEC identified 27 disclosure requirements that were incremental to those in the ASC and referred them to the FASB for potential incorporation into U.S. GAAP. To avoid duplication, the SEC intended to eliminate those disclosure requirements from existing SEC regulations if the FASB incorporated them into the relevant ASC subtopics. The disclosure requirements are currently included in either SEC Regulation S-X or SEC Regulation S-K. ASU 2023-06 adds 14 of the 27 identified disclosure or presentation requirements to the ASC.

For entities, like Park, that are subject to the SEC's existing disclosure requirements, the effective date for each amendment will be the date on which the SEC's removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. The amendments are to be applied prospectively and if by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or S-K, the pending content of the related amendment will be removed from the ASC and will not become effective for any entity. Management intends to adopt the provisions of ASU 2023-06 on their respective effective dates. The adoption of the provisions of ASU 2023-06 is not expected to have a material impact on Park's consolidated financial statements.

ASU 2024-03 - Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): In November 2024, FASB issued ASU 2024-03 - Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40). ASU 2024-03 requires disaggregated disclosure of income statement expenses for public business entities in disclosures within the footnotes to the financial statements. The disclosures will require a footnote disclosure about specific expenses to disaggregate, in a tabular presentation, each relevant expense caption on the income statement that includes any of the following natural expenses: (1) purchases of inventory, (2) employee compensation, (3) depreciation, (4) intangible asset amortization, and (5) depreciation, depletion and amortization recognized as part of oil and gas producing activities and other types of depletion expenses. The tabular disclosure would also include certain other expenses, as applicable.

ASU 2024-03 is effective for public business entities for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted and public business entities are required to adopt ASU 2024-03 prospectively; however, entities are permitted to apply the amendments retrospectively. The adoption of the provisions of ASU 2024-03 is not expected to have an impact on Park's consolidated financial statements, but will impact disclosures.

ASU 2025-06 - Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40) - Targeted Improvements to the Accounting for Internal - Use Software: In September 2025, FASB issued ASU 2025-06 - Intangibles - Goodwill and Other - Internal Use Software (Subtopic 350-40) - Targeted Improvements to the Accounting for Internal -Use Software. ASU 2025-06 removes all references to prescriptive and sequential software development stages (referred to as project stages) throughout Subtopic-350-40. An entity is required to start capitalizing software costs when both of the following occur: (1) Management has authorized and committed to funding the software project and (2) it is probable the project will be completed and the software will be used to perform the function intended.

ASU 2025-06 is effective for annual reporting periods beginning after December 15, 2027 and interim reporting periods within those annual reporting periods. Early adoption is permitted as of the beginning of an annual reporting period. The amendments in this update may be applied using a prospective transition approach, a modified transition approach that is based on the status of the project and whether software costs were capitalized before the date of adoption, or a retrospective transition approach. The adoption of the provisions of ASU 2025-06 is not expected to have a material impact on Park's consolidated financial statements.

ASU- 2025-11 - Interim Reporting (Topic 270) - Narrow Scope Improvements: In December 2025, FASB issued

ASU- 2025-11 - Interim Reporting (Topic 270) - Narrow Scope Improvements. ASU 2025-11 clarifies the scope, form and content, and disclosures required under ASC 270, Interim Reporting. The amendments affect all entities that provide interim financial statements and notes in accordance with U.S. GAAP.

The amendments are effective for interim reporting within annual reporting periods after December 15, 2027. Early adoption is permitted. The adoption of the provisions of ASU 2025-11 is not expected to have a material impact on Park's consolidated financial statements.

ASU 2025-12 - Codification Improvements: In December 2025, FASB issued ASU 2025-12 - Codification Improvements. ASU 2025-12 issued amendments to the Codification to make incremental improvements to generally accepted accounting principles.

The amendments are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual reporting periods. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The adoption of the provisions of ASU 2025-12 is not expected to have a material impact on Park's consolidated financial statements.

Note 3-Business Combination

On February 1, 2026, First Citizens merged into Park, with Park continuing as the surviving corporation. Immediately following the merger, First Citizens National Bank ("FCNB"), a national banking association and a wholly-owned subsidiary of First Citizens, merged into The Park National Bank ("PNB"), with PNB as the surviving bank. This acquisition continues Park's expansion strategy into higher-growth, demographically attractive markets.

The First Citizens acquisition was valued at $324.1 million based on Park's closing stock price per share on January 30, 2026, the last trading day prior to the merger effective date, of $162.94, and resulted in Park issuing 1,988,131 Park common shares as merger consideration in exchange for First Citizens outstanding common stock.

First Citizens' results of operations were included in Park's results beginning February 1, 2026. It is not practicable to determine revenue or net income included in Park's operating results related to First Citizens since the date of the acquisition, as First Citizens' results cannot be separately identified. For the three months and nine months ended September 30, 2026, Park recorded merger-related expenses and other income reducing charges of $7.0 million and $26.5 million, respectively, associated with the First Citizens acquisition. No merger-related expenses were recorded for the three months or nine months ended September 30, 2025.

Park recorded $108.7 million in goodwill, $34.4 million in core deposit intangibles, and $3.6 million in customer relationship intangibles related to wealth management, which reflects the expected synergies and the cost savings resulting from consolidating the operations of PNB and First Citizens. The goodwill is not deductible for income tax purposes as the transaction was accounted for as a tax-free exchange.

The First Citizens acquisition was accounted for under the acquisition method of accounting. Assets acquired and liabilities assumed in the acquisition were recorded at their estimated fair values as of the acquisition date. These estimates were recorded based on preliminary valuations, and these estimates, including the initial accounting for deferred taxes, are considered preliminary as of September 30, 2026, and subject to adjustment for up to one year after the acquisition date.

In many cases, the determination of fair value required management to make estimates about discount rates, expected future cash flows, market conditions, and other future events that are highly subjective in nature and subject to change. While Park believes that the information available on the acquisition date provided a reasonable basis for estimating fair value, additional information may be obtained during the measurement period that would result in changes to the estimated fair value amounts. The measurement period ends on the earlier of one year after the acquisition date or the date Park concludes that all necessary information about the facts and circumstances that existed as of the acquisition date have been obtained. Management anticipates that facts obtained during the measurement period could result in adjustments to the valuation amounts. During the three months ended September 30, 2026, Park made adjustments to decrease acquired asset fair value by $4.3 million and increase acquired liability fair value by $74,000, which resulted in a $4.3 million increase in goodwill.

The following table summarizes the amounts recognized as of the acquisition date for each major class of assets acquired and liabilities assumed:

Loans acquired in the First Citizens acquisition were reviewed to identify any that had experienced a more-than-insignificant deterioration in credit quality since origination. Loans that met established criteria indicating such deterioration are classified as purchased credit deteriorated ("PCD") loans. The remaining loans were classified as purchased seasoned loans ("PSLs"). In accordance with ASU 2025-08, both PCD loans and PSLs are recorded at the purchase price net of expected allowance for credit losses at the time of acquisition. In addition, a non-credit discount or premium is allocated to the loans based on a valuation by a third-party specialist. Under this method, the acquired loans do not incur a provision for credit losses affecting net income at acquisition. However, changes to the allowance for these loans in subsequent periods would be recognized through the provision for credit losses.

Of the $1.6 billion in loans held for investment acquired from First Citizens, $1.5 billion were identified as PSL and $126.4 million were identified as PCD. These loans are summarized in the following table:

The following table presents supplemental pro forma information as if the First Citizens acquisition had occurred as of January 1, 2025. The unaudited pro forma information includes adjustments for interest income on loans acquired, amortization of intangibles arising from the transaction, depreciation expense on property acquired, interest expense on deposits acquired, and the related tax effects. The unaudited pro forma results exclude acquisition‑related costs that were recognized in noninterest expense during the three months and nine months ended September 30, 2026, as these costs were directly attributable to the acquisition and are not expected to have a continuing impact on Park's results of operations. The pro forma information is not necessarily indicative of the results of operations that would have occurred had the transactions been effected on the assumed date. The pro forma amounts below do not reflect any adjustments to the provision for credit losses for acquired loans, or Park's expectations as of the pro forma date of further operating cost savings and other business synergies expected to be achieved, including revenue growth as a result of the acquisition.

Note 4 –Investment Securities

Investment securities at September 30, 2026 and at December 31, 2025, were as follows:

Investment securities in an unrealized loss position at September 30, 2026, were as follows:

Investment securities in an unrealized loss position at December 31, 2025, were as follows:

At September 30, 2026, Park’s debt securities portfolio consisted of $1.2 billion of securities, $1.2 billion of which were in an unrealized loss position with aggregate unrealized losses of $113.2 million. Of the $1.2 billion of securities in an unrealized loss position, $355.9 million were in an unrealized loss position for 12 months or longer. Of the $113.2 million in unrealized losses, $71.7 million were related to Park's "Obligations of U.S. Government sponsored entities" and "U.S. Government sponsored entities' asset-backed securities" portfolios. For non-agency debt securities, Park verified that the current credit ratings remain above investment grade. On a quarterly basis, management reviews the credit profile of each non-agency debt security and assesses whether any impairment to the contractually obligated cash flow is likely to occur. Based on these reviews, management has concluded that the underlying creditworthiness for each security remains sufficient to maintain required payment obligations and that changes in value are largely the result of changes in the yield curve, therefore, unrealized losses have not been recognized into net income. Management does not intend to sell, and it is not more likely than not that management would be required to sell, the securities prior to their anticipated recovery in respect of the unrealized losses. Management believes the value will recover as the securities approach maturity or market interest rates change.

There wasno allowance for credit losses recorded for debt securities AFS at either September 30, 2026 or December 31, 2025. Additionally, for the three-month and nine-month periods ended September 30, 2026 and 2025, there wereno credit-related investment impairment losses recognized.

The amortized cost and estimated fair value of investments in debt securities AFS at September 30, 2026, are shown in the following table by contractual maturity, except for asset-backed securities and collateral loan obligations, which are shown as a single total due to the unpredictability of the timing of principal repayments. Expected maturities may differ from contractual maturities if borrowers have the right to call or prepay obligations with or without call or prepayment penalties.

The tax equivalent yield for certain obligations of state and political subdivisions includes the effect of a taxable equivalent adjustment using a 21% federal corporate income tax rate.

AFS debt securities are those debt securities that would be available to be sold in the future in response to the Corporation’s liquidity needs, changes in market interest rates, and asset-liability management strategies, among other reasons. During thenine-month period ended September 30, 2026, Park sold certain AFS debt securities with a book value of $364.8 million at a gross gain of $2.7 million and sold certain AFS debt securities with a book value of $217.3 million at a gross loss of$1.6 million which sales included certain AFS debt securities acquired in the First Citizens merger. There wereno sales of AFS debt securities during the three-month period ended September 30, 2026. There wereno sales of AFS debt securities during thethree-month or nine-month periods ended September 30, 2025.

Investment securities having a fair value of $1.0 billion and $569.5 million at September 30, 2026 and December 31, 2025, respectively, were pledged to collateralize government and public fund deposits and to secure repurchase agreements.

Note 5 –Other Investment Securities

Other investment securities (as shown on the Consolidated Condensed Balance Sheets) consist of restricted stock investments in the FHLB and the FRB, and equity securities. The FHLB and FRB restricted stock investments are carried at their redemption value. Equity securities with a readily determinable fair value are carried at fair value. Equity securities without a readily determinable fair value are recorded at cost, minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions ("modified cost"). Park's portfolio of equity investments in limited partnerships which provide mezzanine funding ("Partnership Investments") are valued using the net asset value practical expedient in accordance with ASC 820.

The carrying amounts of other investment securities at September 30, 2026 and December 31, 2025 were as follows:

(1) There have been no impairments or downward adjustments made to equity investments carried at modified cost. Cumulatively, upward adjustments of $3.5 million have been recorded as a result of observable price changes. There wereno adjustments recorded during either of the three-month or nine-month periods ended September 30, 2026 or 2025 as a result of observable price changes.

No shares of FHLB stock were purchased or repurchased during the three-month period ended September 30, 2026. During the nine-month period ended September 30, 2026, Park acquired 58,245 shares of FHLB stock with a book value of $5.8 million in connection with the acquisition of First Citizens. During that same period, Park purchased 2,117 shares of FHLB stock with a book value of $212,000 and the FHLB repurchased 61,942 shares of FHLB stock with a book value of $6.2 million.

No shares of FHLB stock were purchased or repurchased during the three-month period ended September 30, 2025. During the nine-month period ended September 30, 2025, Park purchased 4,940 shares of FHLB stock with a book value of $494,000. During the nine-month period ended September 30, 2025, the FHLB repurchased 10,878 shares of FHLB stock with a book value of $1.1 million.

No shares of FRB stock were purchased or sold during the three-month period ended September 30, 2026. During the nine-month period ended September 30, 2026, Park acquired 43,812 shares of FRB stock with a book value of $2.2 million in connection with the acquisition of First Citizens. These shares were immediately redeemed by the FRB upon the close of the First Citizens acquisition. During that same period, Park purchased 199,642 shares of FRB stock with a book value of $10.0 million. No shares of FRB stock were purchased or sold during the three-month or nine-month periods ended September 30, 2025.

During the three-month periods ended September 30, 2026 and 2025, $(215,000) and $(1.7) million, respectively, of losses on equity investments carried at fair value were recorded within "Gain (loss) on equity securities, net" on the Consolidated Condensed Statements of Income. During the nine-month periods ended September 30, 2026 and 2025, $4.2 million and $51,000, respectively, of gains on equity investments carried at fair value were recorded within "Gain (loss) on equity securities, net" on the Consolidated Condensed Statements of Income.

During the three-month periods ended September 30, 2026 and 2025, $1.2 million and $1.1 million, respectively, of gains on equity investments carried at NAV were recorded within “Gain (loss) on equity securities, net” on the Consolidated Condensed Statements of Income. During the nine-month periods ended September 30, 2026 and 2025, $2.1 million and $1.0 million, respectively, of gains on equity investments carried at NAV were recorded within “Gain (loss) on equity securities, net” on the Consolidated Condensed Statements of Income.

Note 6 –Loans

The composition of the loan portfolio at September 30, 2026 and at December 31, 2025 was as follows:

(1)Included within each of commercial, financial and agricultural loans and commercial real estate loans is an immaterial amount of consumer loans that were not broken out by class.

Loans are shown net of deferred origination fees, costs and unearned income of $20.0 million at September 30, 2026, and of $20.1 million at December 31, 2025, which represented a net deferred income position at both dates. Additionally, at September 30, 2026, loans included purchase accounting adjustments of $18.7 million, which represented a net deferred income position. This fair market value purchase accounting adjustment is expected to be recognized into interest income on a level yield basis over the remaining expected life of the loans. At December 31, 2025, there wereno purchase accounting adjustments included in loans.

Overdrawn deposit accounts of $1.4 million and $2.1 million were reclassified to loans at September 30, 2026 and at December 31, 2025, respectively.

Credit Quality

Nonperforming loans consist of nonaccrual loans and loans past due 90 days or more and still accruing.

The following tables present the amortized cost of nonaccrual loans and loans past due 90 days or more and still accruing, by class of loan, at September 30, 2026 and December 31, 2025.

The following tables provide additional detail on nonaccrual loans and the related ACL, by class of loan, at September 30, 2026 and December 31, 2025:

Nonaccrual commercial loans are evaluated on an individual basis and are excluded from the collective evaluation. Additionally, accruing collateral dependent commercial loans to borrowers experiencing financial difficulty are to be individually evaluated and an inquiry is performed to identify any additional loans which do not share similar risk characteristics and are to be individually evaluated. Management’s general practice is to proactively charge down nonaccrual loans individually evaluated to the fair value of the underlying collateral. Nonaccrual consumer loans are collectively evaluated based on similar risk characteristics.

The following tables provide the amortized cost basis of collateral-dependent loans by class of loan, at September 30, 2026 and at December 31, 2025:

Interest income on nonaccrual loans is recognized on a cash basis only when Park expects to receive the entire recorded investment in the loans. The following table presents interest income recognized on nonaccrual loans for the three-month and nine-month periods ended September 30, 2026 and 2025:

The following tables present the aging of the amortized cost in past due loans at September 30, 2026 and at December 31, 2025 by class of loan:

(1) Includes an aggregate of $3.5 million of loans past due 90 days or more and accruing. The remaining loans were past due nonaccrual loans.

(2) Includes an aggregate of $60.3 million of nonaccrual loans which were current with respect to contractual principal and interest payments.

(1) Includes an aggregate of $2.7 million of loans past due 90 days or more and accruing. The remaining loans were past due nonaccrual loans.

(2) Includes an aggregate of $50.5 million of nonaccrual loans which were current with respect to contractual principal and interest payments.

Credit Quality Indicators

Management utilizes past due information as a credit quality indicator across the loan portfolio. Past due information at September 30, 2026 and December 31, 2025 is included in the previous tables. The past due information is the primary credit quality indicator within the following classes of loans: (1) overdrafts in the commercial, financial and agricultural portfolio segment; (2) retail loans in the construction real estate portfolio segment; (3) mortgage loans, HELOC and installment loans in the residential real estate portfolio segment; and (4) consumer loans and check loans in the consumer portfolio segment. The primary credit indicator for commercial loans is based on an internal grading system that grades all commercial loans on a scale from 1 to 8. Credit grades are continuously monitored by the responsible loan officer and adjustments are made when appropriate. A grade of 1 indicates little or no credit risk and a grade of 8 is considered a loss. Commercial loans that are pass-rated (graded a 1 through a 4) are considered to be of acceptable credit risk. Commercial loans graded a 5 (special mention) are considered to be watch list credits and a higher PD is applied to these loans. Loans classified as special mention have potential weaknesses that require management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of Park’s credit position at some future date. Commercial loans graded a 6 (substandard), also considered watch list credits, are considered to represent higher credit risk and, as a result, a higher PD is applied to these loans. Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or the value 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 Park will sustain some loss if the weaknesses are not corrected. Commercial loans graded a 7 (doubtful) are shown as nonaccrual and Park generally charges these loans down to their fair value by taking a partial charge-off or recording an individual reserve. 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. Certain 6-rated loans and all 7-rated loans are placed on nonaccrual status and included within the individually evaluated category. A commercial loan is deemed nonaccrual, and is individually evaluated, when management determines the borrower's ability to perform in accordance with the contractual loan agreement is in doubt. Any commercial loan graded an 8 (loss) is completely charged off.

Based on the most recent analysis performed, the risk category of commercial loans by class of loans at September 30, 2026 and at December 31, 2025 are detailed in the tables below. Also included in the tables detailing loan balances are gross charge offs for the nine months ended September 30, 2026 and for the year ended December 31, 2025. For purposes of the following tables, when a refinancing is treated as a new loan for accounting purposes, the loan is assigned a new origination year based on the date the new loan is recognized.

(1) Included within each of commercial, financial and agricultural loans and commercial real estate loans is an immaterial amount of consumer loans that are not broken out by class.

(1) Included within each of commercial, financial and agricultural loans and commercial real estate loans is an immaterial amount of consumer loans that are not broken out by class.

Park considers the performance of the loan portfolio and its impact on the ACL. For residential and consumer loan classes, Park also evaluates credit quality based on the aging status of the loan, which was previously presented, and by performing status. The following tables present the amortized cost in residential and consumer loans based on performing status and gross charge offs for the nine months ended September 30, 2026 and for the year ended December 31, 2025. Nonperforming loans consisted of nonaccrual loans and loans past due 90 days or more and still accruing. For purposes of the following tables, when a refinancing is treated as a new loan for accounting purposes, the loan is assigned a new origination year based on the date the new loan is recognized.

Loans Acquired with Deteriorated Credit Quality

With the acquisition of First Citizens on February 1, 2026, Park purchased loans for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination. The initial carrying amount of those loans was as follows:

The carrying amount of PCD loans at September 30, 2026 and December 31, 2025 was $111.5 million and $2.5 million, respectively. The allowance for credit losses on PCD loans totaled $4.3 million at September 30, 2026. There wasno allowance for credit losses on PCD loans at December 31, 2025.

Modifications to Borrowers Experiencing Financial Difficulty

Management identifies loans as modifications to borrowers experiencing financial difficulty when a borrower is experiencing financial difficulties and Park has altered the cash flow of the loan as part of a modification or in the loan renewal process. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of the borrower's debt in the foreseeable future without the modification. This evaluation is performed in accordance with the Company’s internal underwriting policy. Park modifies loans to borrowers experiencing financial difficulty by providing principal forgiveness, a term extension, an other-than-insignificant payment delay or an interest rate reduction.

In some cases, Park provides multiple types of modifications on one loan. Typically, one type of modification, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another modification, such as principal forgiveness, may be granted. For the loans included in the combination columns below, multiple types of modifications have been made on the same loan within the current reporting period. The combination is at least two of the following: a term extension, principal forgiveness, an other-than-insignificant payment delay and/or an interest rate reduction.

The starting point for the estimate of the ACL is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. As a result, the effect of most modifications made to borrowers experiencing financial difficulty is already included in the ACL and a change to the ACL is generally not recorded upon modification. When principal forgiveness is provided, the amount of forgiveness is charged off against the ACL.

The following tables present the amortized cost basis of loans at September 30, 2026 and 2025 that were both experiencing financial difficulty and modified during the three months and the nine months ended September 30, 2026 and 2025 by class and type of modification. The percentage of the amortized cost basis of loans that were modified to borrowers in financial difficulty as compared to the amortized cost basis of each class of financing receivable is also presented below.

At September 30, 2026, Park had commitments to lend $4.1 million related to loans that were experiencing both financial difficulty and had been modified during the nine months ended September 30, 2026.

The following tables present the financial effect of the loan modifications presented above to borrowers experiencing financial difficulty for the three months and nine months ended September 30, 2026 and 2025:

Park closely monitors the performance of loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of Park's modification efforts. The following tables provide the performance of loans as of the period end date, of modifications made to borrowers experiencing financial difficulty during the twelve months preceding September 30, 2026 and September 30, 2025, respectively:

The following tables present the amortized cost basis of loans that had a payment default subsequent to modification during the three months and nine months ended September 30, 2026 and 2025 and were modified in the twelve months prior to that default to borrowers experiencing financial difficulty. For these tables, a loan is considered to be in default when it becomes 30 days contractually past due under the modified terms:

Upon the determination that a modified loan (or a portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is charged-off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the ACL is adjusted by the same amounts.

Note 7 –Allowance for Credit Losses

The ACL is an estimate of the expected credit losses on financial assets measured at amortized cost, which is measured using relevant information about past events, including historical credit loss experience on financial assets with similar risk characteristics, current conditions, and reasonable and supportable forecasts that affect the collectability of the remaining cash flows over the contractual term of the financial assets. A provision for (recovery of) credit losses is charged to operations based on management’s periodic evaluation of these and other pertinent factors.

As part of the acquisition of First Citizens, Park recorded a day 1 ACL of $18.5 million. In accordance with ASU 2025-08, the day 1 ACL was recorded as an increase to the ACL with a corresponding increase to Goodwill.

Quantitative Considerations

The ACL is primarily calculated utilizing a DCF model or an undiscounted Expected Loss Model for purchased loans. Key inputs and assumptions used in both models are discussed below:

•First Citizens acquired portfolio - Park elected to utilize its existing 2025 LDA, prepayment study, curtailment study, and funding analysis as the acquired portfolio is similar in credit risk and loss experience to Park’s. This was confirmed through extensive due diligence. Additionally, the current loss driver analysis is calculated heavily utilizing Park’s proxy peer group which is not expected to change significantly in 2026. The ACL on PSLs and PCD loans shares all relevant inputs and assumptions, but utilizes undiscounted credit losses from the analysis to calculate the ACL.

•Forecast model- For each portfolio segment, a LDA was performed in order to identify appropriate loss drivers and create a regression model for use in forecasting cash flows. The LDA analysis utilized Park's own FFIEC Call Report data for the residential real estate portfolio segments. Peer data was incorporated into the analysis for the commercial, financial, and agricultural, commercial real estate, construction real estate, and consumer portfolio segments. Prior to 2025, only Park's own data was used for the commercial, financial and agricultural segment. Park updated the LDA in the fourth quarter of 2025. During the COVID-19 pandemic, macroeconomic indicators showed significant deterioration, however, Park, along with most financial institutions, observed little to no meaningful increase in default activity. This can be attributed to external intervention in the form of deferral programs and government stimulus which is unlikely to reoccur in future downturns. For these reasons, management has excluded data from 2020-2022 in the LDA by using indicator variables during this time period.

•Probability of default – PD is the probability that an asset will be in default within a given time frame. Park has defined default to be when a charge-off has occurred, a loan is placed on nonaccrual, or a loan is greater than 90 days past due. Whenever possible, Park utilizes its own loan-level PDs for the reasonable and supportable forecast period. When loan-level data is not available reflecting the forecasted economic conditions, the LDA is utilized to estimate PDs. In all cases, the LDA is then utilized to determine the long-term historical average, which is reached over the reversion period.

•Loss given default – LGD is the percentage of the asset not expected to be collected due to default. Whenever possible, Park utilizes its own loan-level LGDs for the reasonable and supportable forecast period. When it is not possible to use Park's own LGDs, the LGD is derived using a method referred to as Frye Jacobs. In all cases, the Frye Jacobs method is utilized to calculate LGDs during the reversion period and long-term historical average.

•Prepayments and curtailments – Prepayments and curtailments are calculated based on Park’s own data utilizing a combination of three-year and four-year averages based on the weighted average remaining life of each segment. Prior to 2025, only a three-year average was used. A four-year average was incorporated in 2025 to improve the estimate of prepayments and curtailments rates over the life of loan for longer duration segments. This analysis is updated annually in the fourth quarter and was last updated in the fourth quarter of 2025.

•Forecast and reversion – Park has established a one-year reasonable and supportable forecast period with a one-year straight line reversion to the long-term historical average.

•Economic forecast - Park utilizes a third party to provide economic forecasts under various scenarios, which are weighted in order to reflect model risk in the current economic environment. The scenario weighting is evaluated by management on a quarterly basis.

◦As of September 30, 2025, the "most likely" scenario forecasted Ohio unemployment between 5.05% and 5.49% during the next four quarters. In determining the appropriate weighting of scenarios at September 30, 2025, management considered the range of forecasted unemployment as well as a number of economic indicators. While some economic indications are showing stabilization or slight improvement, volatile and low levels of consumer confidence, higher unemployment rates, the impact of elevated inflation for several years with the impact of tariffs being unknown, the interest rate environment, geopolitical conflict (including conflict related to tariffs), uncertainty regarding fiscal policy of the current political administration, including tariffs, and continued stress in the commercial real estate sector cause uncertainty to the overall economic environment. Considering these factors, management determined it was appropriate to maintain the existing weighting, and weigh the "most likely" scenario 50% and the "moderate recession" scenario 50% at September 30, 2025.

◦As of December 31, 2025, the "most likely" scenario forecasted Ohio unemployment between 5.21% and 5.54% during the next four quarters. In determining the appropriate weighting of scenarios at December 31, 2025, management considered the range of forecasted unemployment as well as a number of economic indicators. While some economic indications are showing stabilization or slight improvement, volatile and low levels of consumer confidence, higher unemployment rates, the impact of elevated inflation for several years with the impact of tariffs being still unknown, the interest rate environment, geopolitical conflict (including conflict related to tariffs), uncertainty regarding fiscal policy of the current political administration, including tariffs, and continued stress in the commercial real estate sector cause uncertainty to the overall economic environment. Considering these factors, management determined it was appropriate to maintain the existing weighting, and weigh the "most likely" scenario 50% and the "moderate recession" scenario 50% at December 31, 2025.

◦As of March 31, 2026, the "most likely" scenario forecasted Ohio unemployment between 4.86% and 4.98% during the next four quarters. In determining the appropriate weighting of scenarios at March 31, 2026, management considered the range of forecasted unemployment as well as a number of economic indicators. While some economic indications are showing stabilization or slight improvement, volatile and low levels of consumer confidence, higher unemployment rates, the impact of elevated inflation for several years with the impact of tariffs being still unknown, the interest rate environment, geo-political conflict (including conflict related to tariffs and the conflict between the U.S. and Iran), uncertainty regarding fiscal policy of the current political administration, and continued stress in the commercial real estate sector cause uncertainty to the overall economic environment. Considering these factors, management determined it was appropriate to maintain the existing weighting, and weigh the "most likely" scenario 50% and the "moderate recession" scenario 50% at March 31, 2026.

◦As of June 30, 2026, the "most likely" scenario forecasted Ohio unemployment between 4.39% and 5.10% during the next four quarters. In determining the appropriate weighting of scenarios at June 30, 2026, management considered the range of forecasted unemployment as well as a number of economic indicators. While some economic indications are showing stabilization or slight improvement, higher levels of inflation, volatile and low levels of consumer confidence, unemployment rate volatility, the interest rate environment, geo-political conflict (including conflict related to tariffs and the conflict between the U.S. and Iran), uncertainty regarding fiscal policy of the current political administration, and continued stress in the commercial real estate sector cause uncertainty to the overall economic environment. Considering these factors, management determined it was appropriate to maintain the existing weighting, and weigh the "most likely" scenario 50% and the "moderate recession" scenario 50% at June 30, 2026.

◦As of September 30, 2026, the "most likely" scenario forecasted Ohio unemployment between 4.13% and 5.22% during the next four quarters. In determining the appropriate weighting of scenarios at September 30, 2026, management considered the range of forecasted unemployment as well as a number of economic indicators. While some economic indications are showing stabilization or slight improvement, continued elevated levels of inflation, volatile and very low levels of consumer confidence, unemployment rate volatility, the interest rate environment, geo-political conflict (including conflict related to tariffs and the conflict between the U.S. and Iran), and uncertainty regarding fiscal policy of the current political administration, to the overall economic environment. Considering these factors, management determined it was appropriate to maintain the existing weighting, and weigh the "most likely" scenario 50% and the "moderate recession" scenario 50% at September 30, 2026. Changes in forecasts, incorporation of an acquired loan portfolio, as well as changes in loan mix resulted in a 12 basis point decrease in the weighted quantitative allowance from December 31, 2025 and a 2 basis point decrease in the weighted quantitative allowance from June 30, 2026.

Qualitative Considerations

Park reviews various internal and external factors to consider the need for any qualitative adjustments to the quantitative model. Factors considered include the following:

•The nature and volume of Park’s financial assets; the existence, growth, and effect of any concentrations of credit and the volume and severity of past due financial assets, the volume of nonaccrual assets, and the volume and severity of adversely classified or graded assets. Specifically, management considers:

◦Trends (e.g., growth, reduction) in specific categories of the loan portfolio, as well as adjustments to the types of loans offered by Park.

◦Level of and trend in loan delinquencies, troubled loans, commercial watch list loans and nonperforming loans.

◦Level of and trend in new nonaccrual loans.

◦Level of and trend in loan charge-offs and recoveries.

•Park's lending policies and procedures, including changes in lending strategies, underwriting standards and practices for collections, charge-offs, and recoveries.

•The quality of Park’s credit review function.

•The experience, ability, and depth of Park’s lending, investment, collection, and other relevant management and staff.

•The effect of other external factors such as the regulatory, legal and technological environments; competition; geopolitical conflict; and events such as natural disasters or pandemics.

•Actual and expected changes in international, national, regional, and local economic and business conditions and developments in the markets in which Park operates that affect the collectability of financial assets.

•Where the U.S. economy is within a given credit cycle.

•The extent that there is government assistance (stimulus).

•Expansion into new markets, including the risks associated with entering new geographic or product markets and the effectiveness of integrating and assimilating underwriting standards, credit administration practices, risk oversight, and portfolio management processes with Park’s existing framework.

Qualitative adjustments amounted to $7.5 million and $3.2 million at September 30, 2026 and December 31, 2025, respectively. Significant qualitative adjustments include the following:

•Helene: Qualitative adjustments included a $650,000 and $561,000 reserve at September 30, 2026 and December 31, 2025, respectively, related to Hurricane Helene which impacted borrowers in Park's Carolina region. This reserve considers the overall population of loans to borrowers in this area. While Helene impacted this region in October 2024, many borrowers are still navigating the insurance claim process and local businesses are waiting to see the full economic impact on tourist season.

•Mortgage loan grant programs: Qualitative adjustments included a $2.6 million and $2.3 million reserve at September 30, 2026 and December 31, 2025, respectively, related to Park's mortgage loan grant programs designed to assist borrowers in attaining home ownership. As of September 30, 2026, the total loans in these mortgage loan grant programs totaled $260.4 million. Delinquency rates within these mortgage loan grant programs have become higher than those of Park's traditional 30-year mortgage portfolio loans. These mortgage loan grant programs require very little, if any, down payment, and the loan-to-value on these loans are generally at 90% or above. For these reasons, management expects that the PD and LGD related to loans within these programs will be higher than that of Park's standard 30-year portfolio loans and established a qualitative factor related to the increased risk of loss on mortgage loans within these programs.

•Former First Citizens loans: Qualitative adjustments included a $3.2 million additional reserve at September 30, 2026 related to the newly acquired First Citizens loan portfolio. The qualitative adjustment reflects risks associated with entry into new markets, the integration of credit administration practices, and a lower quantitative reserve compared to legacy segments. Although pre‑acquisition due diligence indicated a risk profile generally consistent with Park’s existing loan portfolio, the quantitative ACL calculated for former First Citizens loans was significantly below that of the legacy portfolio. In order to take into consideration all of these factors, management added an additional 20 bps reserve to the affected loans, or $3.2 million, as of September 30, 2026. Park believes that the resulting reserve on former First Citizens loans is more in line with the legacy portfolio.

•Expected extension: During the second quarter of 2026, management identified one special mention loan that is reasonably expected to be extended beyond its current contractual term. This same loan is still reasonably expected to be extended beyond its contractual term as of September 30, 2026. As a result, the allowance at September 30, 2026 included an additional qualitative reserve of $706,000 related to this $22.7 million loan to account for the expected extension of the loan term.

ACL Activity

The activity in the ACL for the three-month and nine-month periods ended September 30, 2026 and September 30, 2025 is summarized in the following tables:

Note 8 –Loans Held For Sale

Mortgage loans held for sale are carried at their fair value. At September 30, 2026 and at December 31, 2025, respectively, Park had $13.7 million and $4.0 million in mortgage loans held for sale. These amounts are included in loans on the Consolidated Condensed Balance Sheets and in the residential real estate loan portfolio segment in Note 6 - Loans, and Note 7 - Allowance for Credit Losses. The contractual balance was $13.5 million and $3.9 million at September 30, 2026 and at December 31, 2025, respectively. The gain expected upon sale was $195,000 and $65,000 at September 30, 2026 and at December 31, 2025, respectively. None of these loans were 90 days or more past due or on nonaccrual status at September 30, 2026 or at December 31, 2025.

Note 9 –Goodwill and Other Intangible Assets

The following table shows the activity in goodwill and other intangible assets for three-month and the nine-month periods ended September 30, 2026 and 2025.

The First Citizens acquisition was accounted for under the acquisition method of accounting. Assets acquired and liabilities assumed in the acquisition were recorded at their estimated fair values as of the acquisition date. These estimates were recorded based on preliminary valuations, and these estimates, including the initial accounting for deferred taxes, are considered preliminary as of September 30, 2026, and subject to adjustment for up to one year after the acquisition date. During the three months ended September 30, 2026, adjustments were made to goodwill totaling $4.3 million.

In past years, Park evaluated goodwill for impairment during the second quarter, with financial data as of the immediately prior March 31. To align the impairment analysis more closely with year-end, Park is moving its annual goodwill impairment testing to the fourth quarter, starting with fiscal year 2026. Based on the qualitative analysis performed as of April 1, 2025, the Company determined that goodwill for Park's reporting unit, PNB, was not impaired. No events or circumstances have occurred since April 1, 2025 that would indicate a potential impairment of goodwill.

Acquired Intangible Assets

The following table shows the balance of acquired intangible assets at September 30, 2026 and at December 31, 2025:

The core deposit intangible asset and the customer relationship intangible asset are being amortized, on an accelerated basis, over a period of ten years. Aggregate amortization expense was $1.9 million and $248,000 for the three-month periods and $5.3 million and $795,000 for the nine-month periods ended September 30, 2026 and 2025, respectively.

Estimated amortization expense related to core deposit intangible asset and the customer relationship intangible asset for the remainder of 2026 and the next four years follows:

Note 10 –Investment in Qualified Affordable Housing

Park makes certain equity investments in various limited partnerships that sponsor affordable housing projects. The purposes of these investments are to achieve a satisfactory return on capital, help create affordable housing opportunities, and assist the Company to achieve its goals associated with the Community Reinvestment Act.

The table below details the balances of Park’s affordable housing tax credit investments and related unfunded commitments at September 30, 2026 and December 31, 2025.

Commitments are funded when capital calls are made by the general partner. Park expects that the current commitments will be funded between the remainder of 2026 through 2039.

Park recognized amortization expense of $2.3 million for each of the three-month periods ended September 30, 2026 and 2025, and $6.8 million for each of the nine-month periods ended September 30, 2026 and 2025, which were included within "Income taxes" in the consolidated condensed statements of income. Additionally, during the three months ended September 30, 2026 and 2025, Park recognized tax credits and other benefits from its affordable housing tax credit investments of $2.7 million and $2.9 million, and during the nine months ended September 30, 2026 and 2025, Park recognized tax credits and other benefits from its affordable housing tax credit investments of $8.2 million and $8.5 million, respectively, which were included within "Income taxes" in the consolidated condensed statements of income.

Note 11 –Foreclosed and Repossessed Assets

Park typically transfers a loan to OREO at the time that Park takes deed/title to the real estate property asset. In addition, during the three months ended March 31, 2026, Park acquired $20.3 million of OREO in connection with the acquisition of First Citizens. The carrying amounts of foreclosed real estate properties held at September 30, 2026 and December 31, 2025 are listed below, as well as the recorded investment of loans secured by residential real estate properties for which formal foreclosure proceedings were in process at those dates.

In addition to real estate, Park may also repossess different types of collateral. As of September 30, 2026 and December 31, 2025, Park had $1.1 million and $0.9 million in other repossessed assets which are included in "Other assets" on the Consolidated Condensed Balance Sheets.

Note 12 –Loan Servicing

Park serviced sold mortgage loans of $1.82 billion at September 30, 2026, compared to $1.84 billion at December 31, 2025 and $1.83 billion at September 30, 2025. At September 30, 2026, $2.1 million of the sold mortgage loans were sold with recourse, compared to $2.3 million at December 31, 2025 and $2.4 million at September 30, 2025. Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At both September 30, 2026 and December 31, 2025, management had established reserves of $18,000, to account for expected losses on loan repurchases.

When Park sells mortgage loans with servicing rights retained, these servicing rights are initially recorded at fair value. Park has selected the “amortization method” as permissible within U.S. GAAP, whereby the servicing rights capitalized are amortized in proportion to and over the period of estimated future servicing income with respect to the underlying loan. At the end of each reporting period, the carrying value of MSRs is assessed for impairment with a comparison to fair value. MSRs are carried at the lower of their amortized cost or fair value. The amortization of MSRs is included within "Other service income" in the consolidated condensed statements of income.

Activity for MSRs and the related valuation allowance follows:

Servicing fees included in "Other service income" were $1.2 million for both the three months ended September 30, 2026 and 2025, respectively, and $3.6 million for both the nine months ended September 30, 2026 and 2025, respectively.

Note 13 -Leases

Park is a lessee in several noncancellable operating lease arrangements, primarily for retail branches, administrative and warehouse buildings, ATMs, and certain office equipment within its Ohio, North Carolina, South Carolina, Kentucky, and Tennessee markets. Certain of these leases contain renewal options for periods ranging from one year to five years. Park’s leases generally do not include termination options for either party to the lease or restrictive financial or other covenants. Payments due under the lease arrangements include fixed payments plus, for many of Park’s real estate leases, variable payments such as Park's proportionate share of property taxes, insurance and common area maintenance.

Park's operating lease ROU asset and lease liability are presented in “Operating lease ROU asset" and "Operating lease liability," respectively, on Park's Consolidated Condensed Balance Sheets. The carrying amounts of Park's ROU asset and lease liability at September 30, 2026 were $16.5 million and $17.9 million, respectively. At December 31, 2025, the carrying amounts of Park's ROU asset and lease liability were $15.7 million and $17.1 million, respectively. Park's operating lease expense is recorded in "Occupancy expense" on the Company's Consolidated Condensed Statements of Income.

Other information related to operating leases for the three-month and nine-month periods ended September 30, 2026 and 2025 follows:

(1) Includes a tenant improvement allowance of $524,000 related to the reimbursement of leasehold expenditures for the nine-month period ended September 30, 2025.

Park's operating leases had a weighted average remaining term of 8.3 years and 9.3 years at September 30, 2026 and December 31, 2025, respectively. The weighted average discount rate of Park's operating leases was 4.4% at both September 30, 2026 and at December 31, 2025.

Undiscounted cash flows included in lease liabilities have expected contractual payments as follows:

Note 14 –Repurchase Agreement Borrowings

Securities sold under agreements to repurchase ("repurchase agreements") with customers represent funds deposited by customers, generally on an overnight basis, that are collateralized by investment securities owned by Park. Repurchase agreements with customers are included in "Short-term borrowings" on the Consolidated Condensed Balance Sheets.

All repurchase agreements are subject to terms and conditions of repurchase/security agreements between Park and the customer and are accounted for as secured borrowings. Park's repurchase agreements consist of customer accounts and securities that are pledged on an individual security basis.

At September 30, 2026 and at December 31, 2025, Park's repurchase agreement borrowings totaled $135.8 million and $81.7 million, respectively. These borrowings were primarily collateralized with U.S. Government sponsored entities' asset-backed securities and obligations of U.S. Government sponsored entities with a fair value of $185.8 million and $110.3 million at September 30, 2026 and at December 31, 2025, respectively. Declines in the value of the collateral would require Park to pledge additional securities. At September 30, 2026 and at December 31, 2025, Park had $210.3 million and $119.2 million, respectively, of available unpledged securities.

The table below shows the remaining contractual maturity of repurchase agreements by collateral pledged at September 30, 2026 and at December 31, 2025:

Note 15 -Subordinated Notes

On February 1, 2026, following the acquisition of First Citizens, Park assumed the role of successor to First Citizens in several Trust Agreements and Junior Subordinated Indentures related to the issuance of subordinated notes. The agreements are summarized in the following paragraphs.

First Citizens Subordinated Notes

In March 2005, First Citizens formed First Citizens (TN) Statutory Trust III ("FC Trust III"), a Delaware statutory trust, that issued $5.0 million of FC Trust III's floating rate preferred securities (the “FC III Trust Preferred Securities”) to institutional investors. These FC III Trust Preferred Securities qualify as Tier I capital under FRB guidelines. All of the common securities of FC Trust III are owned by Park. The proceeds from the issuance of the common securities and the FC III Trust Preferred Securities were used by FC Trust III to purchase $5.2 million of junior subordinated notes, which, following the cessation of LIBOR on June 30, 2023, carry a floating rate based on three-month CME Term SOFR plus 206 basis points. The junior subordinated notes represent the sole asset of FC Trust III. The FC III Trust Preferred Securities accrue and pay distributions at a floating rate of three-month CME Term SOFR plus 206 basis points per annum. The FC III Trust Preferred Securities are mandatorily redeemable upon maturity of the junior subordinated notes in March 2035, or upon earlier redemption as provided in the junior subordinated notes. The junior subordinated notes purchased by FC Trust III have been available for redemption since March 2010. As specified in the indenture, if the junior subordinated notes are redeemed prior to maturity, the redemption price will be the principal amount, plus any unpaid accrued interest. In accordance with U.S. GAAP, FC Trust III is not consolidated with Park’s financial statements, but rather the subordinated notes are reflected as a liability.

In March 2007, First Citizens formed First Citizens (TN) Statutory Trust IV ("FC Trust IV"), a Delaware statutory trust, that issued $5.0 million of FC Trust IV's floating rate preferred securities (the “FC IV Trust Preferred Securities”) to institutional investors. These FC IV Trust Preferred Securities qualify as Tier I capital under FRB guidelines. All of the common securities of FC Trust IV are owned by Park. The proceeds from the issuance of the common securities and the FC IV Trust Preferred Securities were used by FC Trust IV to purchase $5.2 million of junior subordinated notes, which, following the cessation of LIBOR on June 30, 2023, carry a floating rate based on three-month CME Term SOFR plus 201 basis points. The junior subordinated notes represent the sole asset of FC Trust IV. The FC IV Trust Preferred Securities accrue and pay distributions at a floating rate of three-month CME Term SOFR plus 201 basis points per annum. The FC IV Trust Preferred Securities are mandatorily redeemable upon maturity of the junior subordinated notes in June 2037, or upon earlier redemption as provided in the junior subordinated notes. The junior subordinated notes purchased by FC Trust IV have been available for redemption since March 2012. As specified in the indenture, if the junior subordinated notes are redeemed prior to maturity, the redemption price will be the principal amount, plus any unpaid accrued interest. In accordance with U.S. GAAP, FC Trust IV is not consolidated with Park’s financial statements, but rather the subordinated notes are reflected as a liability.

Pursuant to First Citizens merger with Southern Heritage Bancshares on October 1, 2014, First Citizens assumed the debentures issued to Southern Heritage Statutory Trust I ("SH Trust I"). In December 2004, Southern Heritage Bancshares formed SH Trust I, a Delaware statutory trust, that issued $5.0 million of SH Trust I's floating rate preferred securities (the “SH I Trust Preferred Securities”) to institutional investors. These SH I Trust Preferred Securities qualify as Tier I capital under FRB guidelines. All of the common securities of SH Trust I are owned by Park. The proceeds from the issuance of the common securities and the SH I Trust Preferred Securities were used by SH Trust I to purchase $5.2 million of junior subordinated notes, which, following the cessation of LIBOR on June 30, 2023, carry a floating rate based on three-month CME Term SOFR plus 231 basis points. The junior subordinated notes represent the sole asset of SH Trust I. The SH I Preferred Securities accrue and pay distributions at a floating rate of three-month CME Term SOFR plus 231 basis points per annum. The SH I Trust Preferred Securities are mandatorily redeemable upon maturity of the junior subordinated notes in December 2034, or upon earlier redemption as provided in the junior subordinated notes. The junior subordinated notes purchased by SH Trust I have been available for redemption since December 2009. As specified in the indenture, if the junior subordinated notes are redeemed prior to maturity, the redemption price will be the principal amount, plus any unpaid accrued interest. In accordance with U.S. GAAP, SH Trust I is not consolidated with Park’s financial statements, but rather the subordinated notes are reflected as a liability.

Repaid Subordinated Notes

As part of the acquisition of Vision’s parent bank holding company (“Vision Parent”) on March 9, 2007, Park acquired a wholly-owned statutory business trust of Vision Parent (“Trust I”). On December 5, 2005, Trust I issued $15.0 million floating rate preferred securities to institutional investors which it used to purchase $15.5 million of junior subordinated notes from Vision. On September 30, 2025, Park redeemed in full, $15.0 million in trust preferred securities at a redemption price in cash equal to 100% of the principal amount, plus accrued and unpaid interest.

On August 20, 2020, Park completed the issuance and sale of $175.0 million aggregate principal amount of its 4.50% Fixed-to-Floating Rate Subordinated Notes due 2030 (the "Subordinated Notes"). On September 1, 2025, Park redeemed in full the Subordinated Notes at a redemption price in cash equal to 100% of the principal amount of the Subordinated Notes, plus accrued and unpaid interest.

All of the repayments described in this Note 15 were made using available cash on hand and did not involve any refinancing or issuance of new debt.

Note 16 -Derivatives

Park uses certain derivative financial instruments (or "derivatives") to meet the needs of its customers while managing the interest rate risk associated with certain transactions. Park does not use derivatives for speculative purposes. A summary of derivative financial instruments utilized by Park follows.

Interest Rate Swaps

Park utilizes interest rate swap agreements (or "interest rate swaps") as part of its asset-liability management strategy to help manage its interest rate risk position and as a means to meet the financing, interest rate and other risk management needs of qualifying commercial banking customers. The notional amount of the interest rate swaps does not represent the amount exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements.

In conjunction with the Carolina Alliance acquisition, Park acquired interest rate swaps related to certain commercial loans. Simultaneously with borrowers entering into interest rate swaps, Carolina Alliance entered into offsetting interest rate swaps executed with a third party, such that Carolina Alliance minimized its net interest rate risk exposure resulting from such transactions. These interest rate swaps had a notional amount totaling $10.4 millionand$13.1 million at September 30, 2026 and at December 31, 2025, respectively.

While these derivatives represent economic hedges, they do not qualify as hedges for accounting purposes. The aggregate fair value of the interest rate swaps is recorded in "Other assets" and "Other liabilities" with changes in fair value recorded in "Miscellaneous Other Income" and "Miscellaneous Other Expense". During thethree-month and nine-month periods ended September 30, 2026 and 2025, no net gain or loss was recorded related to these interest rate swaps.

Summary information about Park's interest rate swaps at September 30, 2026 and at December 31, 2025 follows:

The following table reflects the interest rate swaps included in the consolidated condensed balance sheets at September 30, 2026 and at December 31, 2025.

Mortgage Banking Derivatives

Commitments to fund mortgage loans (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free standing derivatives. In order to hedge the change in interest rates resulting from its commitments to fund the loans, the Company enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into. These mortgage banking derivatives are not designated as hedge relationships. The fair value of an interest rate lock is recorded at the time the commitment to fund the mortgage loan is executed and is adjusted for the expected exercise of the commitment before the loan is funded. Fair values of these mortgage banking derivatives are estimated based on changes in mortgage interest rates from the date the interest on the loan is locked. Changes in the fair values of these derivatives are included in "Other service income" in the consolidated condensed statements of income.

At September 30, 2026 and at December 31, 2025, Park had $9.9 million and $6.0 million, respectively, of interest rate lock commitments. The fair value of these mortgage banking derivatives was reflected by a derivative asset of $161,000 and $115,000 at September 30, 2026 and at December 31, 2025, respectively.

Other Derivatives

In connection with the sale during 2009 of the Class B Visa Inc. shares held by Park, Park entered into a swap agreement with the purchaser of the shares. The swap agreement adjusts for dilution in the conversion ratio of the Class B Visa shares resulting from certain Visa litigation. At September 30, 2026 and December 31, 2025, the fair value of the swap agreement liability of$323,000 and $268,000, respectively, represented an estimate of the exposure based upon probability-weighted potential Visa litigation losses.

Note 21 –Fair Value

The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three levels of inputs that Park uses to measure fair value are as follows:

•Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that Park has the ability to access as of the measurement date.

•Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.

•Level 3: Significant unobservable inputs that reflect Park's own assumptions about the assumptions that market participants would use in pricing an asset or liability. This could include the use of internally developed models, financial forecasting and similar inputs.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the balance sheet date. When possible, the Company looks to active and observable markets to price identical assets or liabilities. When identical assets and liabilities are not traded in active markets, the Company looks to observable market data for similar assets and liabilities. However, certain assets and liabilities are not traded in observable markets and Park must use other valuation methods to develop a fair value. The fair value of individually evaluated collateral dependent loans is typically based on the fair value of the underlying collateral, which is estimated through third-party appraisals in accordance with Park's valuation requirements under its commercial and real estate loan policies.

Assets and Liabilities Measured at Fair Value on a Recurring Basis:

The following table presents assets and liabilities measured at fair value on a recurring basis:

The following methods and assumptions were used by the Company in determining the fair value of the financial assets and financial liabilities discussed above:

Fair value swap: The fair value of the swap agreement entered into with the purchaser of the Visa Class B shares represents an internally developed estimate of the exposure based upon probability-weighted potential Visa litigation losses and is classified as Level 3.

Interest rate swaps: The fair values of interest rate swaps are based on valuation models using observable market data as of the measurement date (Level 2).

Investment securities: Fair values for investment securities are based on quoted market prices, where available (Level 1). If quoted market prices are not available, fair values are based on quoted market prices of comparable instruments (Level 2). This includes the use of "matrix pricing" to value debt securities absent the exclusive use of quoted prices. For equity securities where quoted prices or market prices of similar securities are not available, fair values are calculated using alternative valuation techniques, based on unobservable inputs (Level 3). For debt securities where quoted prices or market prices of similar securities are not available, fair values are calculated using DCF (Level 3).

Mortgage interest rate lock commitments: Mortgage IRLCs are based on current secondary market pricing and are classified as Level 2.

Mortgage loans held for sale: Mortgage loans held for sale are carried at their fair value. Mortgage loans held for sale are estimated using market prices for similar product types and, therefore, are classified in Level 2.

The following tables present a reconciliation of the beginning and ending balances of the Level 3 inputs for the three-month and nine-month periods ended September 30, 2026 and 2025, for financial instruments measured on a recurring basis and classified as Level 3:

One debt security with a fair value of $404,000 as of December 31, 2025, was transferred out of Level 3 and into Level 2, during the nine months ended September 30, 2026, because observable market data became available for this investment. Level 3 debt securities consisted of two debt securities at September 30, 2026 and at December 31, 2025, which were valued using a discounted cash flow calculation. Significant unobservable inputs included a credit spread assumption which ranged from 0.75% to 2.53% at September 30, 2026, and ranged from 3.67% to 4.45% at December 31, 2025.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis:

The following methods and assumptions were used by the Company in determining the fair value of assets and liabilities measured at fair value on a nonrecurring basis as described below:

Individually evaluated collateral dependent loans: When a loan is individually evaluated, it is valued at the lower of cost or fair value. Collateral dependent loans which are individually evaluated and carried at fair value have been partially charged off or receive allocations of the allowance for credit losses. For collateral dependent loans, fair value is generally based on real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales approach and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments result in a Level 3 classification of the inputs for determining fair value. Collateral is then adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the customer and the customer’s business, resulting in a Level 3 fair value classification. Individually evaluated loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Additionally, valuations for all collateral dependent loans are updated annually, either through independent valuations by a licensed appraiser or a VOV performed by an internal licensed appraiser, in accordance with Company policy. A VOV can only be used in select circumstances and verifies that the original appraised value has not deteriorated through property inspection, consideration of market conditions, and performance of all valuation methods utilized in a prior valuation.

Loans individually evaluated for impairment include all internally classified commercial nonaccrual loans and accruing collateral dependent loans to borrowers experiencing financial difficulty.

OREO: Assets acquired through or in lieu of loan foreclosure are initially recorded at fair value less costs to sell when acquired. The carrying value of OREO is not re-measured to fair value on a recurring basis, but is subject to fair value adjustments when the carrying value exceeds the fair value, less estimated selling costs. Fair value is based on recent real estate appraisals and is updated at least annually. These appraisals may utilize a single valuation approach or a combination of approaches including the comparable sales approach and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments result in a Level 3 classification of the inputs for determining fair value.

Appraisals for both individually evaluated collateral dependent loans and OREO are performed by licensed appraisers. Appraisals are generally obtained to support the fair value of collateral. In general, there are three types of appraisals received by the Company: real estate appraisals, income approach appraisals, and lot development loan appraisals. These are discussed below:

•Real estate appraisals typically incorporate measures such as recent sales prices for comparable properties. Appraisers may make adjustments to the sales prices of the comparable properties as deemed appropriate based on the age, condition or general characteristics of the subject property. Management generally applies a 15% discount to real estate appraised values which management expects will cover all disposition costs (including selling costs). This 15% discount is based on historical discounts to appraised values on sold OREO.

•Income approach appraisals typically incorporate the annual net operating income of the business divided by an appropriate capitalization rate, as determined by the appraiser. Management generally applies a 15% discount to income approach appraised values which management expects will cover all disposition costs (including selling costs).

•Lot development loan appraisals are typically performed using a DCF analysis. Appraisers determine an anticipated absorption period and a discount rate that takes into account an investor’s required rate of return based on recent comparable sales. Management generally applies a 6% discount to lot development appraised values, which is an additional discount above the net present value calculation included in the appraisal, to account for selling costs.

MSRs: MSRs are carried at the lower of cost or fair value. MSRs do not trade in active, open markets with readily observable prices. For example, sales of MSRs do occur, but precise terms and conditions typically are not readily available. As such, management, with the assistance of a third-party specialist, determines fair value based on the discounted value of the future cash flows estimated to be received. Significant inputs include the discount rate and assumed prepayment speeds. The calculated fair value is then compared to market values where possible to ascertain the reasonableness of the valuation in relation to current market expectations for similar products. Accordingly, MSRs are classified as Level 2.

The following tables present assets and liabilities measured at fair value on a nonrecurring basis. Individually evaluated collateral dependent loans secured by real estate are carried at fair value if they have been charged down to fair value or if a specific valuation allowance has been established. At September 30, 2026 and December 31, 2025, there were no accruing, individually evaluated, collateral-dependent loans carried at fair value. A new cost basis is established at the time a property is initially recorded in OREO. OREO properties are carried at fair value if a devaluation has been taken with respect to the property's value subsequent to the initial measurement.

(1) Includes commercial, financial and agricultural loans in which real estate collateral was obtained subsequent to loan origination.

(1) Includes commercial, financial and agricultural loans in which real estate collateral was obtained subsequent to loan origination.

The tables below provide additional detail on those nonaccrual individually evaluated loans which are recorded at fair value as well as the remaining nonaccrual individually evaluated loan portfolio not included above. The remaining nonaccrual individually evaluated loans consist of 1) loans which are not collateral dependent, 2) loans which are not secured by real estate, and 3) loans carried at cost as the fair value of the underlying collateral or the present value of expected future cash flows on each of the loans exceeded the book value for each respective credit.

The income (expense) from credit adjustments related to nonaccrual individually evaluated loans carried at fair value was $23,000 and $(124,000) for the three-month periods ended September 30, 2026 and 2025, respectively, and was $(1.4) million and $(76,000) for thenine-month periods ended September 30, 2026 and 2025, respectively.

MSRs totaled $13.4 million at September 30, 2026, $35,000 of which was recorded at fair value and included a valuation allowance of $4,000. The remaining $13.4 million was recorded at cost, as the fair value exceeded cost at September 30, 2026. At December 31, 2025, MSRs totaled $13.7 million, $35,000 of which was recorded at fair value and included a valuation allowance of $3,000. The remaining $13.7 million was recorded at cost, as the fair value exceeded cost at December 31, 2025. There wasno expense related to MSRs carried at fair value for the three-month period ended September 30, 2026. The income (expense) related to MSRs carried at fair value was $18,000 for the three-month period ended September 30, 2025, and was $(1,000) and $14,000 for thenine-month periods ended September 30, 2026 and 2025, respectively.

Total OREO held by Park at September 30, 2026 and December 31, 2025 was $18.6 million and $0.7 million, respectively. There was $18.2 million of OREO held by Park that was carried at fair value due to fair value adjustments made subsequent to the initial OREO measurement at September 30, 2026. At December 31, 2025, there wasno OREO held by Park that was carried at fair value due to fair value adjustments made subsequent to the initial OREO measurement. The net expense related to OREO fair value adjustments was $1.5 million and $2.1 million during the three-month andnine-month periods ended September 30, 2026, respectively, and was $60,000 during thenine-month periods ended September 30, 2025. There wasno expense related to OREO carried at fair value during the three-month period ended September 30, 2025.

Note 22 -Segment Information

Park's chief operating decision maker is Park's Chief Executive Officer and President. While the chief decision maker monitors the operating results of its lines of business, operations are managed and financial performance is evaluated on a consolidated basis. Accordingly, all of the financial service operations are considered by management to be aggregated inone reportable operating segment.

The segment is determined by the level of information provided to the chief operating decision maker, who uses such information to review performance of various components of the business, which are then aggregated if operating performance, products, and services are similar. The chief operating decision maker will evaluate the financial performance of Park's business components such as by evaluating interest income, interest expense, other revenue streams, significant expenses, and budget to actual results in assessing Park's segment and in the determination of allocation resources. The chief operating decision maker uses consolidated net income to benchmark Park against its peers. The benchmarking analysis coupled with monitoring of budget to actual results are used in assessment of performance and in establishing compensation. Loans, investments, deposits, and fiduciary income provide the revenues in the banking operation. Interest expense, provisions for credit losses, and payroll/benefits provide the significant expenses in the banking operation. All operations are domestic.

Accounting policies for Park's reportable segment are the same as described in Note 1 - Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements included in Park’s 2025 Form 10-K. Segment performance is evaluated using consolidated net income. Information reported internally for performance assessment by the chief operating decision maker follows, inclusive of reconciliations of significant segment totals to the financial statements.

Note 23 -Revenue from Contracts with Customers

All of Park's revenue from contracts with customers within the scope of ASC 606 is recognized within "Other income" in the Consolidated Condensed Statements of Income. All of Park's operations are considered by management to be aggregated in one reportable segment.

The following table presents the Corporation's sources of other income by revenue stream for the three-month andnine-month periods ended September 30, 2026 and September 30, 2025:

(1) "Other Service Income" totaled $4.3 million and $3.7 million for the three months ended September 30, 2026 and 2025, respectively. Of this aggregate revenue approximately $2.1 million and $1.9 million was within the scope of ASC 606, with the remaining $2.2 million and $1.8 million consisting primarily of certain residential real estate loan fees which were out of scope for the three months ended September 30, 2026 and 2025, respectively.

(2) Not within the scope of ASC 606.

(3) "Miscellaneous Income" included brokerage income, safe deposit box rentals, gains/losses on asset sales and miscellaneous bank fees totaling $1.4 million and $2.6 million for the three months ended September 30, 2026 and 2025, respectively, all of which were within the scope of ASC 606.

(1) "Other Service Income" totaled $12.1 million and $10.4 million for the nine months ended September 30, 2026 and 2025, respectively. Of this aggregate revenue approximately $5.4 million and $5.1 million was within the scope of ASC 606, with the remaining $6.7 million and $5.3 million consisting primarily of certain residential real estate loan fees which were out of scope for the nine months ended September 30, 2026 and 2025, respectively.

(2) Not within the scope of ASC 606.

(3) "Miscellaneous Income" included brokerage income, safe deposit box rentals, gains/losses on asset sales and miscellaneous bank fees totaling $2.9 million and $3.4 million for the nine months ended September 30, 2026 and 2025, respectively, all of which were within the scope of ASC 606.

A description of Park's material revenue streams accounted for under ASC 606 follows:

Income from fiduciary activities (gross): Park earns fiduciary fee income and investment brokerage fees from its contracts with wealth management customers for various fiduciary and investment-related services. These fees are earned over time as the Company provides the contracted monthly and quarterly services and are generally assessed based on the market value of the trust assets.

Service charges on deposit accounts and ATM fees: The Corporation earns fees from the Corporation's deposit customers for transaction-based, account maintenance, and overdraft services. Fees for transaction-based services, which include services such as ATM use fees, stop payment charges, statement rendering fees, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Corporation fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are generally recognized at the end of the month, representing the period over which the Corporation satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance.

Other service income: Other service income includes income from (1) the sale and servicing of loans sold to the secondary market, (2) incentive income from third-party credit card issuers, and (3) loan customers for various loan-related activities and services. Income related to the sale and servicing of loans sold to the secondary market is included within "Other service income", but is not within the scope of ASC 606. Services that fall within the scope of ASC 606 are recognized as revenue when the Company satisfies the Company's performance obligation to the customer.

Debit card fee income: Park earns interchange fees from debit cardholder transactions conducted primarily through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, net of card network fees, concurrently with the transaction processing services provided to the cardholder.
