Disclaimer Non-GAAP Financial Measures This presentation contains certain financial information determined by methods other than in accordance with accounting principles generally accepted in the U.S. (“GAAP”). Management believes that the disclosure of these “non-GAAP” financial measures presents additional information which, when read in conjunction with Park’s consolidated financial statements prepared in accordance with GAAP, assists in analyzing Park’s operating performance, ensures comparability of operating performance from period to period, and facilitates comparisons with the performance of Park’s peer financial holding companies, while eliminating certain non-operational effects of acquisitions. Additionally, Park believes this financial information is utilized by regulators and market analysts to evaluate a company’s financial condition, and therefore, such information is useful to investors. The non-GAAP financial measures should not be viewed as substitutes for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. A reconciliation from the most directly comparable GAAP financial measures to the non-GAAP financial measures used in this presentation is provided on pages 35 and 36 of this presentation.

Preparation to Cross $10 Billion in Assets • Since Q3 2020, Park has been strategically managing the balance sheet size to stay under $10 billion in assets(1) using one-way sell deposits and other balance sheet strategies. • In Q3 2022, Park engaged Promontory (third-party professional services firm) to assess Park’s preparedness as it relates to regulatory expectations that typically present themselves when banks cross $10 billion in assets. • From Q3 2022 to present, Park continues to invest in people, processes and technology to better prepare for the enhanced regulatory expectations. • Park believes that it is well positioned for increased regulatory expectations in the event assets exceed $10 billion, whether by acquisition, merger or organically. P A R K N A T I O N A L C O R P O R A T I O N 11 (1) Park crossed $10 billion in assets two times since then, once on September 30, 2021, and again on September 30, 2023.

Specialty Lending • Park has successfully operated in the specialty finance area for many years, specifically focusing on turbo-prop and light jets and structured finance lending to non-bank consumer finance companies. Net charge-offs in specialty lending have not materially impacted Park’s overall net charge-off rates over the last 10 years. • Park acquired Scope Leasing, Inc. in the mid-1990’s. Scope follows the same conservative underwriting posture as the commercial loan portfolio. Its lending team has years of industry experience and maintains a narrow focus as to acceptable aircraft underlying loans. Scope had loans of $313.9 million, or 4.02% of total loans, outstanding as of December 31, 2024. Scope offers aircraft loans from $200,000 to $5 million to individuals, small businesses, and major corporations across the country. • Park entered the structured finance lending business in 2008. It features a traditional asset-based lending line of business with daily cash collections, periodic customer audits, and an attractive risk/reward dynamic. The structured finance loans consist of loans to non-bank consumer finance companies throughout the nation. These asset-based loans are collateralized by cash flows from individuals, typically from auto loans financed by the non-bank consumer finance company. These loans have conservative underwriting and are subject to intensive loan monitoring. Structured finance loans represented $325.4 million, or 4.16% of total loans, outstanding as of December 31, 2024.
