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 2024-02 - Codification Improvements - Amendments to Remove References to Concepts Statements: In March 2024, FASB issued ASU 2024-02 - Codification Improvements - Amendments to Remove References to the Concepts Statements. ASU 2024-02 contains amendments to the Codification that remove references to various Concepts Statements. In most cases the references were extraneous and not required to understand or apply the guidance. In other instances, the references were used in previous Statements to provide guidance on certain topical areas.

ASU 2024-02 is effective for public business entities for fiscal years beginning after December 15, 2024. The adoption of ASU 2024-02 did not have an impact on Park's consolidated financial statements.

Issued But Not Yet Effective Accounting Standards

ASU 2023-09- Income Taxes (Topic 740) Improvement to Income Tax Disclosures

In December 2023, FASB issued ASU 2023-09 - Income Taxes (Topic 740): Improvements to Income Tax Disclosures. ASU 2023-09 will require entities to disclose more detailed information in the reconciliation of their statutory tax rate to their effective tax rate. ASU 2023-09 also requires entities to disclose more detailed information about income taxes paid, including by jurisdiction.

ASU 2023-09 is effective for public business entities for annual reporting periods beginning after December 15, 2024 and interim periods beginning after December 15, 2025. The adoption of the provisions of ASU 2023-09 is not expected to have an impact on Park's consolidated financial statements, but will impact disclosures.

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) deprecation, 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.

Note 3 –Investment Securities

Investment securities at March 31, 2025 and at December 31, 2024, were as follows:

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

Investment securities in an unrealized loss position at December 31, 2024, were as follows:

At March 31, 2025, Park’s debt securities portfolio consisted of $938.2 million of securities, $838.2 million of which were in an unrealized loss position with aggregate unrealized losses of $65.4 million. Of the $838.2 million of securities in an unrealized loss position, $667.7 million were in an unrealized loss position for 12 months or longer. Of the $65.4 million in unrealized losses, $47.2 million were related to Park's "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 ACL recorded for debt securities AFS at either March 31, 2025 or December 31, 2024. Additionally, for the three months ended March 31, 2025 and 2024, there wereno credit-related investment impairment losses recognized.

The amortized cost and estimated fair value of investments in debt securities AFS at March 31, 2025, 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.

(1) 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.

During the three-month period ended March 31, 2024, Park sold certain AFS debt securities with a book value of $31.2 million at a gross loss of $398,000. There wereno sales of debt securities AFS during the three-month period ended March 31, 2025.

Investment securities having a fair value of $661.5 million and $599.2 million at March 31, 2025 and December 31, 2024, respectively, were pledged to collateralize government and public fund deposits, to secure repurchase agreements and as collateral for FHLB advance borrowings.

Note 4 –Other Investment Securities

Other investment securities consist of restricted stock investments in the FHLB and the FRB, and equity securities. The restricted FHLB and FRB 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 NAV practical expedient in accordance with ASC 820.

The carrying amounts of other investment securities at March 31, 2025 and December 31, 2024 were as follows:

(1) There have been no impairments or downward adjustments made to equity investments carried at modified cost. Cumulatively, upward adjustments of $1.4 million have been recorded as a result of observable price changes. There wereno adjustments recorded during the three months ended March 31, 2025 or March 31, 2024 as a result of observable price changes.

No shares of FHLB stock were purchased during the three months ended March 31, 2025. During the three months ended March 31, 2024, Park purchased 2,246 shares of FHLB stock with a book value of $225,000.

During the three months ended March 31, 2025, the FHLB repurchased 6,243 shares of FHLB stock with a book value of $624,000. During the three months ended March 31, 2024, the FHLB repurchased 45,630 shares of FHLB stock with a book value of $4.6 million.

No shares of FRB stock were purchased or sold during the three months ended March 31, 2025 or 2024.

During the three months ended March 31, 2025 and 2024, $(563,000) and $3,000, respectively, of (losses) gains on equity investments carried at fair value were recorded within "Loss on equity securities, net" on the Consolidated Condensed Statements of Income.

During the three months ended March 31, 2025 and 2024, $(299,000) and $(690,000), respectively, of losses on equity investments carried at NAV were recorded within “Loss on equity securities, net” on the Consolidated Condensed Statements of Income.

Note 5 –Loans

The composition of the loan portfolio at March 31, 2025 and at December 31, 2024 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 March 31, 2025, and of $20.4 million at December 31, 2024, which represented a net deferred income position at both dates. At March 31, 2025 and December 31, 2024, loans included purchase accounting adjustments of $493,000 and $669,000, respectively, which represented a net deferred income position at each date. 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.

Overdrawn deposit accounts of $1.1 million and $1.5 million were reclassified to loans at March 31, 2025 and at December 31, 2024, 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 March 31, 2025 and December 31, 2024.

The following tables provide additional detail on nonaccrual loans and the related ACL, by class of loan, at March 31, 2025 and December 31, 2024:

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 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 March 31, 2025 and at December 31, 2024:

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 periods ended March 31, 2025 and 2024:

The following tables present the aging of the amortized cost in past due loans at March 31, 2025 and at December 31, 2024 by class of loan:

(1) Includes an aggregate of $1.2 million of loans past due 90 days or more and accruing. The remaining loans were past due nonaccrual loans.

(2) Includes an aggregate of $44.2 million of nonaccrual loans which were current with respect to contractual principal and interest payments.

(1) Includes an aggregate of $1.8 million of loans past due 90 days or more and accruing. The remaining loans were past due nonaccrual loans.

(2) Includes an aggregate of $44.1 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 March 31, 2025 and December 31, 2024 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 March 31, 2025 and at December 31, 2024 are detailed in the tables below. Also included in the tables detailing loan balances are gross charge offs for the three months ended March 31, 2025 and for the year ended December 31, 2024.

(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 three months ended March 31, 2025 and for the year ended December 31, 2024. Nonperforming loans consisted of nonaccrual loans and loans past due 90 days or more and still accruing.

Loans and Leases Acquired with Deteriorated Credit Quality

PCD loans are individually evaluated on a quarterly basis to determine if a reserve is necessary. At March 31, 2025 and at December 31, 2024, there wasno ACL on PCD loans. The carrying amount of accruing loans acquired with deteriorated credit quality at March 31, 2025 and at December 31, 2024 was $2.1 million and $2.2 million, respectively. The carrying amount of nonaccrual loans acquired with deteriorated credit quality was $546,000 and $551,000 at March 31, 2025 and at December 31, 2024, respectively.

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 March 31, 2025 and 2024 that were both experiencing financial difficulty and modified during the three months ended March 31, 2025 and 2024 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 March 31, 2025, Park had commitments to lend $2.7 million related to loans which were both experiencing financial difficulty and modified during the three months ended March 31, 2025.

The following tables present the financial effect of the loan modifications presented above to borrowers experiencing financial difficulty for the three months ended March 31, 2025 and 2024:

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 table provides the performance of loans as of the period end date, of modifications made to borrowers experiencing financial difficulty during the twelve months preceding March 31, 2025:

There were $3.5 million in loans modified to borrowers experiencing financial difficulty that had been modified during the twelve months ended March 31, 2024 that were 60-89 days past due as of March 31, 2024 in the Commercial, financial, and agricultural loan portfolio segment. There were $9,000 in loans modified to borrowers experiencing financial difficulty that had been modified during the previous twelve months that were 30-59 days past due as of March 31, 2024 in the Commercial, financial, and agricultural loan portfolio segment. All other loans modified to borrowers experiencing financial difficulty during the twelve months ended March 31, 2024 were less than 30 days past due as of March 31, 2024.

The following tables present the amortized cost basis of loans that had a payment default subsequent to modification during the three months ended March 31, 2025 and 2024 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 6 –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 credit losses is charged to operations based on management’s periodic evaluation of these and other pertinent factors.

Quantitative Considerations

The ACL is primarily calculated utilizing a DCF model. Key inputs and assumptions used in this model are discussed below:

•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 commercial, financial and agricultural and residential real estate portfolio segments. Peer data was incorporated into the analysis for the commercial real estate, construction real estate, and consumer portfolio segments. Park updated the LDA in the fourth quarter of 2024. 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 three-year average. This analysis is updated annually in the fourth quarter and was last updated in the fourth quarter of 2024.

•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 March 31, 2024, the "most likely" scenario forecasted Ohio unemployment between 4.31% and 4.79% during the next four quarters. In determining the appropriate weighting of scenarios at March 31, 2024, management considered the range of forecasted unemployment as well as a number of economic indicators. The continued elevated levels of inflation, volatile levels of consumer confidence, continued elevated interest rates, financial system stress and geopolitical conflict (including the conflicts between Russia and Ukraine and between Israel and Hamas) and stress in the commercial real estate sector, continued to cause uncertainty as 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, 2024.

◦As of December 31, 2024, the "most likely" scenario forecasted Ohio unemployment between 4.48% and 4.60% during the next four quarters. In determining the appropriate weighting of scenarios at December 31, 2024, management considered the range of forecasted unemployment as well as a number of economic indicators. While some economic indications are showing improvement and stabilization, volatile levels of consumer confidence, higher unemployment rates, the impact of elevated inflation for several years with no immediate indications of sustained decline, the interest rate environment, financial system stress, and geopolitical conflict (including the conflicts between Russia and Ukraine and between Israel and Hamas) and stress in the commercial real estate sector, continued to cause uncertainty as 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, 2024.

◦As of March 31, 2025, the "most likely" scenario forecasted Ohio unemployment between 4.51% and 4.85% during the next four quarters. In determining the appropriate weighting of scenarios at March 31, 2025, management considered the range of forecasted unemployment as well as a number of economic indicators. While some economic indications are showing stabilization, lower levels of consumer confidence, higher unemployment rates, the impact of elevated inflation for several years with no immediate signs of sustained decline, the interest rate environment, financial system stress, geopolitical conflict, uncertainty regarding fiscal policy of the new political administration, including tariffs, and 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, 2025.

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).

Qualitative adjustments amounted to $1.1 million and $1.2 million at March 31, 2025 and December 31, 2024, respectively. Qualitative adjustments included a $719,000 and $757,000 reserve at March 31, 2025 and December 31, 2024, 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. Management will continue to evaluate potential losses as a result of Hurricane Helene as additional information becomes available.

ACL Activity

The activity in the ACL for the three-month periods ended March 31, 2025 and March 31, 2024 is summarized in the following tables:

ACL Summary

Loans collectively evaluated for impairment in the following tables include all performing loans at March 31, 2025 and at December 31, 2024, as well as nonperforming loans internally classified as consumer loans. Nonperforming consumer loans are not typically individually evaluated for impairment, but receive a portion of the statistical allocation of the ACL. Loans individually evaluated for impairment include all internally classified commercial nonaccrual loans which are individually evaluated for impairment in accordance with U.S. GAAP. Additionally, accruing collateral dependent commercial loans to borrowers experiencing financial difficulty are individually evaluated. (See Note 1 - Summary of Significant Accounting Policies of the Notes to consolidated financial statements included in Park’s 2024 Form 10-K).

The composition of the ACL at March 31, 2025 and at December 31, 2024 was as follows:

Note 7 –Loans Held For Sale

Mortgage loans held for sale are carried at their fair value. At March 31, 2025 and at December 31, 2024, respectively, Park had $4.9 million and $5.6 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 5 - Loans, and Note 6 - Allowance for Credit Losses. The contractual balance was $4.8 million and $5.5 million at March 31, 2025 and at December 31, 2024, respectively. The gain expected upon sale was $67,000 and $72,000 at March 31, 2025 and at December 31, 2024, respectively. None of these loans were 90 days or more past due or on nonaccrual status at March 31, 2025 or at December 31, 2024.

Note 8 –Goodwill and Other Intangible Assets

The following table shows the activity in goodwill and other intangible assets for the three-month periods ended March 31, 2025 and 2024.

Park evaluates goodwill for impairment during the second quarter of each year, with financial data as of the immediately prior March 31. Based on the qualitative analysis performed as of April 1, 2024, the Company determined that goodwill for Park's reporting unit, PNB, was not impaired.

Acquired Intangible Assets

The following table shows the balance of acquired intangible assets at March 31, 2025 and at December 31, 2024:

Core deposit intangible assets are being amortized, on an accelerated basis, over a period of ten years. Aggregate amortization expense was $274,000 and $320,000 for the three months ended March 31, 2025 and 2024, respectively.

Estimated amortization expense related to core deposit intangible assets for the remainder of 2025 and the next four years follows:

Note 9 –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 March 31, 2025 and December 31, 2024.

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 2025 through 2039.

Park recognized amortization expense of $2.3 million and $2.1 million for the three months ended March 31, 2025 and 2024, respectively, which were included within "Income taxes" in the consolidated condensed statements of income. Additionally, during the three months ended March 31, 2025 and 2024, Park recognized tax credits and other benefits from its affordable housing tax credit investments of $2.8 million and $2.6 million, respectively, which were included within "Income taxes" in the consolidated condensed statements of income.

Note 10 –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. The carrying amounts of foreclosed real estate properties held at March 31, 2025 and December 31, 2024 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. At March 31, 2025 and December 31, 2024, Park had $1.3 million and $1.2 million, respectively, in other repossessed assets which are included in "Other assets" on the Consolidated Condensed Balance Sheets.

Note 11 –Loan Servicing

Park serviced sold mortgage loans of $1.84 billion at March 31, 2025, $1.86 billion at December 31, 2024 and $1.91 billion at March 31, 2024. At March 31, 2025, $2.4 million of the sold mortgage loans were sold with recourse, compared to $2.5 million at December 31, 2024 and $2.9 million at March 31, 2024. Management closely monitors the delinquency rates on the mortgage loans sold with recourse. At March 31, 2025 and December 31, 2024, management had established reserves of $18,000 and $50,000, respectively, 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 and $1.3 million for the three months ended March 31, 2025 and 2024, respectively.

Note 12 -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, and Kentucky 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 March 31, 2025 were $16.3 million and $17.7 million, respectively. At December 31, 2024, the carrying amounts of Park's ROU asset and lease liability were $15.7 million and $16.5 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 periods ended March 31, 2025 and 2024 follows:

(1) Includes a tenant improvement allowance of $524,000 related to the reimbursement of leasehold expenditures for the three-month period ended March 31, 2025.

Park's operating leases had a weighted average remaining term of 9.8 years at both March 31, 2025 and December 31, 2024. The weighted average discount rate of Park's operating leases was 4.0% and 3.8% at March 31, 2025 and at December 31, 2024, respectively.

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

Note 13 –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 which are pledged on an individual security basis.

At March 31, 2025 and at December 31, 2024, Park's repurchase agreement borrowings totaled $81.0 million and $90.4 million, respectively. These borrowings were collateralized with U.S. Government sponsored entities' asset-backed securities with a fair value of $106.0 million and $124.1 million at March 31, 2025 and at December 31, 2024, respectively. Declines in the value of the collateral would require Park to pledge additional securities. At March 31, 2025 and at December 31, 2024, Park had $392.8 million and $440.2 million, respectively, of available unpledged securities.

The table below shows the remaining contractual maturity of repurchase agreements by collateral pledged at March 31, 2025 and at December 31, 2024:

Note 14 -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 $14.9 millionand$15.4 million at March 31, 2025 and at December 31, 2024, respectively.

All of the Company's interest rate swaps were determined to be fully effective during each of thethree-month periods ended March 31, 2025 and March 31, 2024. As such, no amount of ineffectiveness has been included in net income. Therefore, the aggregate fair value of the interest rate swaps is recorded in "Other assets" and "Other liabilities" with changes in fair value recorded in "Other comprehensive income (loss)". The amount included in "Accumulated other comprehensive loss, net of tax" would be reclassified to net income should the hedges no longer be considered effective. Park expects the outstanding hedges to remain fully effective during the remaining respective terms of the interest rate swaps.

Summary information about Park's interest rate swaps at March 31, 2025 and at December 31, 2024 follows:

The following table reflects the interest rate swaps included in the consolidated condensed balance sheets at March 31, 2025 and at December 31, 2024.

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 condensed consolidated statements of income.

At March 31, 2025 and at December 31, 2024, Park had $7.3 million and $4.2 million, respectively, of interest rate lock commitments. The fair value of these mortgage banking derivatives was reflected by a derivative asset of $132,000 and $85,000 at March 31, 2025 and at December 31, 2024, respectively.

Other Derivatives

In connection with the sale of Park’s Class B Visa shares during 2009, Park entered into a swap agreement with the purchaser of the shares. The swap agreement adjusts for dilution in the conversion ratio of Class B Visa shares resulting from certain Visa litigation. At March 31, 2025 and December 31, 2024, the fair value of the swap agreement liability of$233,000 and $103,000, respectively, represented an estimate of the exposure based upon probability-weighted potential Visa litigation losses.

Note 15 –Accumulated Other Comprehensive Loss

Other comprehensive income (loss) components, net of tax, are shown in the following table for the three-month periods ended March 31, 2025 and 2024:

During the three-month period ended March 31, 2024, there was $398,000 ($314,000 net of tax) reclassified out of accumulated other comprehensive loss due to a net loss on the sale of debt securities. This loss was recorded within "Loss on the sale of debt securities, net" on the consolidated condensed statements of income. During the three-month period ended March 31, 2025, there wereno reclassifications out of accumulated other comprehensive loss.

Note 16 –Earnings Per Common Share

The following table sets forth the computation of basic and diluted earnings per common share for the three months ended March 31, 2025 and 2024.

Park awarded 49,350 PBRSUs and 59,165 PBRSUs to certain employees during the three months ended March 31, 2025 and 2024, respectively.

No common shares were repurchased during the three months ended March 31, 2025 or 2024, respectively, to fund the PBRSUs or the common shares to be awarded to directors of Park and to directors of Park's subsidiary PNB (and its divisions) as well as pursuant to Park's previously announced stock repurchase authorizations..

Note 17 -Share-Based Compensation

The 2017 Employees LTIP was adopted by the Board of Directors of Park on January 23, 2017 and was approved by Park's shareholders at the Annual Meeting of Shareholders on April 24, 2017. The 2017 Employees LTIP makes equity-based awards and cash-based awards available for grant to employee participants in the form of incentive stock options, nonqualified stock options, SARs, restricted stock, restricted stock units, other stock-based awards and cash-based awards. Under the 2017 Employees LTIP,750,000 common shares are authorized to be delivered in connection with grants under the 2017 Employees LTIP. The common shares to be delivered under the 2017 Employees LTIP are to consist of either common shares currently held or common shares subsequently acquired by Park as treasury shares, including common shares purchased in the open market or in private transactions. At March 31, 2025,175,650 common shares were available for future grants under the 2017 Employees LTIP.

The 2017 Non-Employee Directors LTIP was adopted by the Board of Directors of Park on January 23, 2017 and was approved by Park's shareholders at the Annual Meeting of Shareholders on April 24, 2017. The 2017 Non-Employee Directors LTIP makes equity-based awards and cash-based awards available for grant to non-employee director participants in the form of nonqualified stock options, SARs, restricted stock, restricted stock units, other stock-based awards, and cash-based awards.

During the three months ended March 31, 2025 and 2024, the Compensation Committee of the Board of Directors of Park granted awards of PBRSUs, under the 2017 Employees LTIP, covering an aggregate of 49,350 common shares and 59,165 common shares, respectively, to certain employees of Park and its subsidiaries.

At March 31, 2025, Park reported 183,537 nonvested PBRSUs. The number of PBRSUs earned or settled will depend on the level of achievement with respect to certain performance criteria over a three-year period. The PBRSUs are also subject to subsequent service-based vesting.

A summary of changes in the common shares subject to nonvested PBRSUs for the three months ended March 31, 2025 follows. PBRSUs herein represent the maximum number of nonvested PBRSUs. The fair value of the PBRSUs was determined using the quoted price of Park stock on the date of grant.

(1) The number of PBRSUs earned depends on the level of achievement with respect to certain performance criteria. Adjustment herein, if any, represents the difference between the maximum number of common shares which could be earned and the actual number earned for those PBRSUs as to which the performance period was completed.

(2) Nonvested amount herein represents the maximum number of nonvested PBRSUs. As of March 31, 2025, an aggregate of 181,892 PBRSUs were expected to vest.

A summary of awards vested during the three months ended March 31, 2025 and 2024 follows:

Share-based compensation expense of $2.0 million was recognized for both the three-month periods ended March 31, 2025 and 2024, respectively.

The following table details expected additional share-based compensation expense related to PBRSUs outstanding at March 31, 2025:

Note 18 –Benefit Plans

Park has a noncontributory defined benefit pension plan (the "Pension Plan") covering substantially all of its employees. The Pension Plan provides benefits based on an employee’s years of service and compensation.

There wereno Pension Plan contributions for either of the three-month periods ended March 31, 2025 or 2024. Additionally, no contributions are expected to be made during the remainder of 2025.

The following table shows the components of net periodic pension benefit income:

Park has entered into Supplemental Executive Retirement Plan Agreements (the “SERP Agreements”) with certain key officers of Park and its subsidiaries which provide defined pension benefits in excess of limits imposed by federal tax law. The expense for the Corporation related to the SERP Agreements for the three months ended March 31, 2025 and 2024 was as follows:

Note 19 –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). For 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 periods ended March 31, 2025 and 2024, for financial instruments measured on a recurring basis and classified as Level 3:

Level 3 corporate debt securities consist of a single debt security at both March 31, 2025 and December 31, 2024 which was valued using a discounted cash flow calculation. Significant unobservable inputs include the credit spread assumption which was 3.67% at both March 31, 2025 and December 31, 2024.

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 March 31, 2025 and December 31, 2024, there were no PCD loans carried at fair value. Additionally, 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. There wereno OREO properties recorded at fair value as of March 31, 2025.

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 expense from credit adjustments related to nonaccrual individually evaluated loans carried at fair value was $68,000 and $35,000 for thethree-month periods ended March 31, 2025 and 2024, respectively.

MSRs totaled $13.8 million at March 31, 2025. Of this $13.8 million MSR carrying balance, $0.4 million was recorded at fair value and included a valuation allowance of $17,000. The remaining $13.4 million was recorded at cost, as the fair value exceeded cost at March 31, 2025. At December 31, 2024, MSRs totaled $13.9 million. Of this $13.9 million MSR carrying balance, $0.4 million was recorded at fair value and included a valuation allowance of $19,000. The remaining $13.5 million was recorded at cost, as the fair value exceeded cost at December 31, 2024. The income related to MSRs carried at fair value was $2,000 and $25,000 for thethree-month periods ended March 31, 2025 and 2024, respectively.

Total OREO held by Park at March 31, 2025 and December 31, 2024 was $0.1 million and $0.9 million, respectively. At March 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. At December 31, 2024, there was$938,000 of OREO held by Park that was carried at fair value due to fair value adjustments made subsequent to the initial OREO measurement. The net income related to OREO fair value adjustments was $39,000 for thethree-month period ended March 31, 2025. There wasno net (expense) income related to OREO fair value adjustments for thethree-month period ended March 31, 2024.

The following tables present qualitative information about Level 3 fair value measurements for financial instruments measured at fair value on a nonrecurring basis at March 31, 2025 and December 31, 2024:

Note 20 -Segment Information

Park's chief operating decision maker is Park's Chairman and Chief Executive Officer. 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 in one 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 2024 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 21 -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 thethree-month periods ended March 31, 2025 and March 31, 2024:

(1) "Other Service Income" totaled $2.9 million and $2.5 million for the three months ended March 31, 2025 and 2024, respectively. Of this aggregate revenue approximately $1.4 million and $1.2 million was within the scope of ASC 606, with the remaining $1.5 million and $1.3 million consisting primarily of certain residential real estate loan fees which were out of scope for the three months ended March 31, 2025 and 2024, 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 $0.2 million and $0.9 million for the three months ended March 31, 2025 and 2024, 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.

Gain or loss on sale of OREO, net: The Corporation records a gain or loss from the sale of OREO when control of the property transfers to the buyer, which generally occurs at the time of delivery of an executed deed. When Park finances the sale of OREO to the buyer, the Corporation assesses whether the buyer is committed to perform the buyer's obligation under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Corporation adjusts the transaction price and related gain (loss) on sale if a significant financing component is present.
