Park National Corporation

Item 2.02 - Results of Operations and Financial Condition On October 26, 2026, Park National Corporation (“Park”) issued a news release (the “Financial Results News Release”) announcing financial results for the three and nine months ended September 30, 2026. A copy of the Financial Results News Release is included as Exhibit 99.1 to this Current Report on Form 8-K and incorporated by reference herein. Non-U.S. GAAP Financial Measures Item 7.01 of this Current Report on Form 8-K as well as the Financial Results News Release contain non-U.S. GAAP (generally accepted accounting principles in the United States or "U.S. GAAP") financial measures where management believes them to be helpful in understanding Park’s results of operations or financial position. Where non-U.S. GAAP financial measures are used, the comparable U.S. GAAP financial measures, as well as the reconciliation from the comparable U.S. GAAP financial measures, can be found in the Financial Results News Release. Items Impacting Comparability of Period Results From time to time, revenue, expenses and/or taxes are impacted by items judged by management of Park to be outside of ordinary banking activities and/or by items that, while they may be associated with ordinary banking activities, are so unusually large that their impact is believed by management of Park at that time to be infrequent or short-term in nature. Most often, these items impacting comparability of period results are due to merger and acquisition activities and revenue and expenses related to former Vision Bank loan relationships. In other cases, they may result from management's decisions associated with significant corporate actions outside of the ordinary course of business. Even though certain revenue and expense items are naturally subject to more volatility than others due to changes in market and economic environment conditions, as a general rule, volatility alone does not result in the inclusion of an item as one impacting comparability of period results. For example, changes in the provision for credit losses (aside from those related to former Vision Bank loan relationships), gains (losses) on equity securities, net, and asset valuation adjustments, reflect ordinary banking activities and are, therefore, typically excluded from consideration as items impacting comparability of period results. Management believes the disclosure of items impacting comparability of period results provides a better understanding of Park's performance and trends and allows management to ascertain which of such items, if any, to include or exclude from an analysis of Park's performance; i.e., within the context of determining how that performance differed from expectations, as well as how, if at all, to adjust estimates of future performance taking such items into account. Items impacting comparability of the results of particular periods are not intended to be a complete list of items that may materially impact current or future period performance. Calculation of Non-U.S. GAAP Financial Measures Park's management uses certain non-U.S. GAAP financial measures to evaluate Park's performance. Specifically, management reviews the return on average tangible equity, the return on average tangible assets, the tangible equity to tangible assets ratio, tangible book value per common share and pre-tax, pre-provision net income. Management has included in the Financial Results News Release information relating to the annualized return on average tangible equity, the annualized return on average tangible assets, the tangible equity to tangible assets ratio, tangible book value per common share and pre-tax, pre-provision net income for the three months ended and at September 30, 2026, June 30, 2026, and September 30, 2025 and for the nine months ended September 30, 2026 and September 30, 2025. For the purpose of calculating the annualized return on average tangible equity, a non-U.S. GAAP financial measure, net income for each period is divided by average tangible equity during the period. Average tangible equity equals average shareholders' equity during the applicable period less average goodwill and other intangible assets during the applicable period. For the purpose of calculating the annualized return on average tangible assets, a non-U.S. GAAP financial measure, net income for each period is divided by average tangible assets during the period. Average tangible assets equals average assets during the applicable period less average goodwill and other intangible assets during the applicable period. For the purpose of calculating the tangible equity to tangible assets ratio, a non-U.S. GAAP financial measure, tangible equity is divided by tangible assets. Tangible equity equals total shareholders' equity less goodwill and other intangible assets, in each case at period end. Tangible assets equal total assets less goodwill and other intangible assets, in each case at period end. For the purpose of calculating tangible book value per common share, a non-U.S. GAAP financial measure, tangible equity is divided by the number of common shares outstanding, in each case at period end. For the purpose of calculating pre-tax, pre-provision net income, a non-U.S. GAAP financial measure, income taxes and the provision for credit losses are added back to net income, in each case during the applicable period. Management believes that the disclosure of the annualized return on average tangible equity, the annualized return on average tangible assets, the tangible equity to tangible assets ratio, tangible book value per common share and pre-tax, pre-provision net income presents additional information to the reader of the consolidated financial statements, which, when read in conjunction with the consolidated financial statements prepared in accordance with U.S. 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 and bank holding companies, while eliminating certain non-operational effects of acquisitions. In the Financial Results News Release, Park has provided a reconciliation of average tangible equity from average shareholders' equity, average tangible assets from average assets, tangible equity from total shareholders' equity, tangible assets from total assets, and pre-tax, pre-provision net income from net income solely for the purpose of complying with SEC Regulation G and not as an indication that the annualized return on average tangible equity, the annualized return on average tangible assets, the tangible equity to tangible assets ratio, tangible book value per common share and pre-tax, pre-provision net income are substitutes for the annualized return on average equity, the annualized return on average assets, the total shareholders' equity to total assets ratio, book value per common share and net income, respectively, as determined in accordance with U.S. GAAP. FTE (fully taxable equivalent) Financial Measures Interest income, yields, and ratios on a FTE basis are considered non-U.S. GAAP financial measures. Management believes net interest income on a FTE basis provides an insightful picture of the interest margin for comparison purposes. The FTE basis also allows management to assess the comparability of revenue arising from both taxable and tax-exempt sources. The FTE basis assumes a corporate federal statutory tax rate of 21 percent. In the Financial Results News Release, Park has provided a reconciliation of FTE interest income solely for the purpose of complying with SEC Regulation G and not as an indication that FTE interest income, yields and ratios are substitutes for interest income, yields and ratios, as determined in accordance with U.S. GAAP. Information Furnished Under Items 2.02 and 7.01 The information contained in Item 2.02 and Item 7.01 of this Current Report on Form 8‑K, including Exhibit 99.1, shall not be deemed 'filed' for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, and shall not be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act except as expressly set forth by specific reference in such filing.

Item 7.01 - Regulation FD Disclosure On February 1, 2026, First Citizens Bancshares, Inc., a Tennessee corporation (“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. FCNB’s former operations now comprise Park’s newly established Tennessee region. On the acquisition date, First Citizens had $2.6 billion in total assets, $1.6 billion in total loans, and $2.2 billion in total deposits. The acquisition was valued at $324.1 million and resulted in Park issuing 1,988,131 Park common shares as merger consideration in exchange for First Citizens outstanding common stock. For the nine months ended September 30, 2026, Park recorded $26.5 million of merger-related expenses and other income reducing charges associated with the First Citizens acquisition. 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. Accordingly, the preliminary estimates and assumptions are subject to change and the final acquisition accounting may differ materially from the amounts presented herein. 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. Financial Results Net income for the three months ended September 30, 2026 of $56.9 million represented a $9.8 million, or 20.7%, increase compared to $47.2 million for the three months ended September 30, 2025. Pre-tax, pre-provision net income for the three months ended September 30, 2026 of $69.8 million represented a $7.7 million, or 12.4%, increase compared to $62.1 million for the three months ended September 30, 2025. Net income for the nine months ended September 30, 2026 of $157.4 million represented a $19.9 million, or 14.5%, increase compared to $137.4 million for the nine months ended September 30, 2025. Pre-tax, pre-provision net income for the nine months ended September 30, 2026 of $201.6 million represented a $25.3 million, or 14.4%, increase compared to $176.3 million for the nine months ended September 30, 2025. Net income for each of the three months ended September 30, 2026, June 30, 2026 and September 30, 2025 and for the nine months ended September 30, 2026 and September 30, 2025 included several items of income and expense, including merger-related expenses, that impacted comparability of period results. These items are detailed in the "Financial Reconciliations" section within the Financial Results News Release. The following discussion provides additional information regarding Park's financial results for the third quarter and first nine months of 2026. Overview The following table reflects Park's net income for the first, second and third quarters of 2026, for the first nine months of 2026 and 2025 (the nine months ended September 30), and for the year ended December 31, 2025.

The increase was a result of a $93.3 million increase in interest income, partially offset by a $12.3 million increase in interest expense. The $93.3 million increase in interest income was due to a $81.0 million increase in interest income on loans and a $12.3 million increase in investment income. The $81.0 million increase in interest income on loans was primarily the result of a $1.61 billion (or 20.34%) increase in average loans, from $7.90 billion for the nine months ended September 30, 2025 to $9.51 billion for the nine months ended September 30, 2026, as well as an increase in the yield on loans, which increased 8 basis points to 6.40% for the nine months ended September 30, 2026, compared to 6.32% for the nine months ended September 30, 2025. Interest income on loans was impacted by the acquisition of First Citizens on February 1, 2026. The newly formed Tennessee region contributed $68.7 million to loan interest income during the nine months ended September 30, 2026, including purchase accounting accretion of $1.6 million. The $12.3 million increase in investment income was primarily the result of a $443.6 million (or 32.03%) increase in average investments, including money market investments, from $1.38 billion for the nine months ended September 30, 2025 to $1.83 billion for the nine months ended September 30, 2026. This increase was also impacted by an increase in the yield on investments, including money market investments, which increased 11 basis points to 3.58% for the nine months ended September 30, 2026, compared to 3.47% for the nine months ended September 30, 2025. The increase in average investments was primarily due to the acquisition of First Citizens'. The $12.3 million increase in interest expense was due to a $17.1 million increase in interest expense on deposits, partially offset by a $4.8 million decrease in interest expense on borrowings. The $17.1 million increase in interest expense on deposits was the result of a $1.65 billion (or 28.29%) increase in average on-balance sheet interest bearing deposits from $5.83 billion for the nine months ended September 30, 2025, to $7.48 billion for the nine months ended September 30, 2026. This increase was partially offset by a decrease in the cost of deposits of 7 basis points, from 1.74% for the nine months ended September 30, 2025 to 1.67% for the nine months ended September 30, 2026. Interest expense on deposits was impacted by the acquisition of First Citizens' which contributed $27.7 million to interest expense on deposits during the nine months ended September 30, 2026. The $4.8 million decrease in interest expense on borrowings was the result of a decrease in the cost of borrowings of 153 basis points, from 3.82% for the nine months ended September 30, 2025 to 2.29% for the nine months ended September 30, 2026 as well as a $114.4 million (or 45.53%) decrease in average borrowings from $251.3 million for the nine months ended September 30, 2025, to $136.9 million for the nine months ended September 30, 2026. The balance of average borrowings was impacted by the redemption of subordinated debt. On September 1, 2025, $175.0 million of subordinated debt was repaid, followed by an additional repayment of $15.0 million of subordinated debt on September 30, 2025. The provision for credit losses of $6.3 million for the nine months ended September 30, 2026 represented a decrease of $1.4 million, compared to $7.6 million for the nine months ended September 30, 2025. Refer to the “Credit Metrics and Provision for Credit Losses” section for additional details regarding the level of the provision for credit losses recognized in each period presented. The table below reflects Park's total other income for the nine months ended September 30, 2026 and 2025. (Dollars in thousands) 2026 2025 $ change % change ──────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────────── Other income: Income from fiduciary activities $ 39,317 $ 33,931 $ 5,386 15.9% Service charges on deposit accounts 10,519 7,499 3,020 40.3% Other service income 12,128 10,383 1,745 16.8% Debit card fee income 23,337 19,300 4,037 20.9% Bank owned life insurance income 5,697 4,833 864 17.9% ATM fees 1,256 1,073 183 17.1% Gain on sale of debt securities, net 1,084 — 1,084 N.M.

Total other income was impacted by the acquisition of First Citizens' which added $9.0 million to total other income for the nine months ended September 30, 2026. The $5.4 million increase in income from fiduciary activities was largely due to a 10.2% increase in the average market value of assets under management. The market value of assets under management as of September 30, 2026 was $9.9 billion, of which $288.7 million was from the Tennessee region. The newly formed Tennessee region contributed $1.3 million to income from fiduciary activities for the nine months ended September 30, 2026. The $3.0 million increase in service charges on deposits was largely due to an increase in non-sufficient funds fees and maintenance fees on deposits as a result of the acquisition of First Citizens. The $1.7 million increase in other service income was mainly due to an increase in mortgage related other service income. The newly formed Tennessee region contributed $1.6 million to other service income for the nine months ended September 30, 2026. The $4.0 million increase in debit card fee income was primarily related to an increase in sales and debit card transactions. The newly formed Tennessee region contributed $3.4 million to debit card fee income for the nine months ended September 30, 2026. The change in gain on sale of debt securities, net was due to net gains on the sale of debt securities of $1.1 million recorded during the nine months ended September 30, 2026. There were no sales of debt securities for the nine months ended September 30, 2025. The securities sold during the nine months ended September 30, 2026 were acquired from First Citizens'. The change in gain on equity securities, net was due to net gains on both equity securities carried at fair value and capital investments during the nine months ended September 30, 2026 compared to lower net gains on equity securities carried at fair value and on capital investments during the same period of 2025. The table below reflects Park's total other expense for the nine months ended September 30, 2026 and 2025.

Included within total other expense are merger-related costs, along with the expanded other expense base that stems from the acquisition of First Citizens. Total other expense for the nine months ended 2026 included $26.3 million in merger-related expenses and $38.4 million related to Park's newly formed Tennessee region and other acquired entities. The breakout of these expenses is detailed in the table below.

The $2.5 million increase in adjusted employee benefits expense was primarily related to increases in group insurance expense, partially offset by decreases in other employee benefit expenses. The $870,000 increase in adjusted occupancy expense was primarily related to increases in expenses connected to strategic initiatives and increases in maintenance and repairs expense. The $4.9 million increase in adjusted data processing fees was mainly related to an increase in software related expenses and ATM and debit card processing expense. Data processing fees in the Tennessee region reflect the costs of running two core systems until operational conversion, which occurred in the third quarter of 2026. The $3.6 million decrease in adjusted professional fees and services was primarily due to decreases in consulting expenses, credit services expense, temporary wage expense and other professional fees, partially offset by increases in legal services expense and appraisal fee expense. The $3.8 million increase in adjusted miscellaneous expense is primarily due to an increase in other non-loan related losses and allowance for unfunded credit loss expense.
