The forward-looking statements are based on management's expectations and are subject to a number of risks and uncertainties, including those described in Park's Annual Report on Form 10-K for the fiscal year ended December 31, 2025, as updated by our filings with the SEC.

Risks and uncertainties that could cause actual results to differ include, without limitation: (1) the ability to execute our business plan successfully and manage strategic initiatives; (2) the impact of current and future economic and financial market conditions, including unemployment rates, inflation, interest rates, supply-demand imbalances, and geopolitical matters; (3) factors impacting the performance of our loan portfolio, including real estate values, financial health of borrowers, and loan concentrations; (4) the effects of monetary and fiscal policies, including interest rates, money supply, and inflation; (5) changes in federal, state, or local tax laws; (6) the impact of changes in governmental policy and regulatory requirements on our operations; (7) changes in consumer spending, borrowing, and saving habits; (8) changes in the performance and creditworthiness of customers, suppliers, and counterparties; (9) increased credit risk and higher credit losses due to loan concentrations; (10) volatility in mortgage banking income due to interest rates and demand; (11) adequacy of our internal controls and risk management programs; (12) competitive pressures among financial services organizations; (13) uncertainty regarding changes in banking regulations and other regulatory requirements; (14) our ability to meet heightened supervisory requirements and expectations; (15) the impact of changes in accounting policies and practices on our financial condition; (16) the reliability and accuracy of assumptions and estimates used in applying critical accounting estimates; (17) the potential for higher future credit losses due to changes in economic assumptions; (18) the ability to anticipate and respond to technological changes and our reliance on third-party vendors; (19) operational issues related to and capital spending necessitated by the implementation of information technology systems on which we are highly dependent; (20) the ability to secure confidential information and deliver products and services through computer systems and telecommunications networks; (21) the impact of security breaches or failures in operational systems; (22) the impact of geopolitical instability and trade policies on our operations including the imposition of tariffs and retaliatory tariffs; (23) the impact of changes in credit ratings of government debt and financial stability of sovereign governments; (24) the effect of stock market price fluctuations on our asset and wealth management businesses; (25) litigation and regulatory compliance exposure; (26) availability of earnings and excess capital for dividend declarations; (27) the impact of fraud, scams, and schemes on our business; (28) the impact of natural disasters, pandemics, and other emergencies on our operations; (29) potential deterioration of the economy due to financial, political, or other shocks; (30) impact of healthcare laws and potential changes on our costs and operations; (31) the ability to grow deposits and maintain adequate deposit levels, including by mitigating the effect of unexpected deposit outflows on our financial condition; (32) risks related to the completed acquisition of First Citizens Bancshares, Inc., including the possibility that anticipated benefits are not realized as expected, difficulties integrating the two companies, and potential adverse reactions to customer, business, or employee relationships; and (33) other risk factors related to the banking industry.

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 32-34 of this presentation.

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 $358.8 million, or 3.71% of total loans, outstanding as of March 31, 2026. 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 $268.8 million, or 2.78% of total loans, outstanding as of March 31, 2026.
