Park National Corporation Discloses Third-Quarter 2026 Operating Results and Non-GAAP Metrics

Park National Corporation (NYSE American:PRK), an Ohio-based financial holding company headquartered at 50 North Third Street, Newark, Ohio, filed a current report on October 26, 2026 under Item 2.02 (Results of Operations and Financial Condition) and Item 7.01. The filing announces that on that same date, Park issued a Financial Results News Release covering the three and nine months ended September 30, 2026. The news release is incorporated by reference as Exhibit 99.1.

According to the filing, management uses several non-U.S. GAAP financial measures to evaluate performance. These include the annualized return on average tangible equity, 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. The filing explains the calculation methodology for each: for example, average tangible equity equals average shareholders' equity less average goodwill and other intangible assets, and pre-tax, pre-provision net income is derived by adding income taxes and the provision for credit losses back to net income. All non-GAAP measures are reconciled to their nearest U.S. GAAP equivalents in the news release, the filing notes, "solely for the purpose of complying with SEC Regulation G and not as an indication" that these measures are substitutes for GAAP equivalents.

The filing also describes the company's framework for "items impacting comparability of period results," which management uses to identify revenue, expenses, or taxes considered outside ordinary banking activities or judged infrequent in nature, including those related to merger and acquisition activities and former Vision Bank loan relationships. The filing states that changes in the provision for credit losses (other than those related to former Vision Bank relationships), gains or losses on equity securities, net, and asset valuation adjustments are typically excluded from this category. Fully taxable equivalent interest income figures assume a 21 percent corporate federal statutory tax rate.
