Innovation. Engagement. Performance. 2 Cautionary Statement Regarding Forward-Looking Information This document contains "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are those that do not relate to historical facts and that are based on current assumptions, beliefs, estimates, expectations and projections, many of which, by their nature, are inherently uncertain and beyond our control. Forward-looking statements may relate to various matters, including our financial condition, results of operations, plans, objectives, future performance, business or industry, and usually can be identified by the use of forward-looking words, such as "anticipates," "assumes," "believes," "can," "continues," "could," "enable," "estimates," "expects," "forecasts," "goal," "intends," "likely," "may," "might," "objective," "plans," "positioned," "potential," "projects," "remains," "should," "target," "trend," "will," "would," or similar words or expressions or variations thereof, and the negative thereof, but these terms are not the exclusive means of identifying such statements. You should not place undue reliance on forward-looking statements, as they are subject to risks and uncertainties, including, but not limited to, those described below. When considering these forward- looking statements, you should keep in mind these risks and uncertainties, as well as any cautionary statements we may make. There are various important factors that could cause future results to differ materially from historical performance and any forward-looking statements. Factors that might cause such differences, include, but are not limited to: • the credit risk associated with the substantial amount of commercial loans and leases in our loan portfolio; • the volatility of the mortgage banking business; • changes in market interest rates, the U.S. federal government shutdown and the unpredictability of monetary, tax and other policies of government agencies, including tariffs or the imposition of new tariffs, trade wars, barriers or restrictions, or threats of such actions; • the impact of changes in interest rates on the value of our investment securities portfolios; • changes in our ability to obtain liquidity as and when needed to fund our obligations as they come due, including as a result of adverse changes to our credit ratings; • the risk associated with uninsured deposit account balances; • regulatory limits on our ability to receive dividends from our subsidiaries and pay dividends to our shareholders; • our ability to recruit and retain qualified banking professionals; • the financial soundness of other financial institutions and the impact of volatility in the banking sector on us; • changes and instability in economic conditions and financial markets, in the regions in which we operate or otherwise, including a contraction of economic activity, economic downturn or uncertainty and international conflict; • our ability to continue to invest in technological improvements as they become appropriate or necessary; • any interruption in or breach in security of our information systems, or other cybersecurity risks; • risks associated with reliance on third-party vendors and artificial intelligence; • risks associated with the use of models, estimations and assumptions in our business; • the effects of adverse weather events and public health emergencies; • the risks associated with acquiring other banks and financial services businesses, including integration into our existing operations; • the extensive federal and state regulations, supervision and examination governing almost every aspect of our operations, and potential expenses associated with complying with such regulations; • our ability to comply with the consent orders entered into by First National Bank of Pennsylvania with the Department of Justice and the North Carolina State Department of Justice, and related costs and potential reputational harm; • changes in federal, state or local tax rules and regulations or interpretations, or accounting policies, standards and interpretations; • the effects of climate change and related legislative and regulatory initiatives; and • any reputation, credit, interest rate, market, operational, litigation, legal, liquidity, regulatory and compliance risk resulting from developments related to any of the risks discussed above. FNB cautions that the risks identified here are not exhaustive of the types of risks that may adversely impact FNB and actual results may differ materially from those expressed or implied as a result of these risks and uncertainties, including, but not limited to, the risk factors and other uncertainties described under Item 1A. Risk Factors and the Risk Management sections of our 2024 Annual Report on Form 10-K (including the MD&A section), our subsequent 2025 Quarterly Reports on Form 10-Q (including the risk factors and risk management discussions) and our other 2025 filings with the Securities and Exchange Commission (SEC), which are available on our corporate website at https://www.fnb-online.com/about-us/investor- information/reports-and-filings or the SEC's website at www.sec.gov. We have included our web address as an inactive textual reference only. Information on our website is not part of our SEC filings. You should treat forward-looking statements as speaking only as of the date they are made and based only on information then actually known to FNB. FNB does not undertake, and specifically disclaim any obligation to update or revise any forward-looking statements to reflect the occurrence of events or circumstances after the date of such statements except as required by law.

Innovation. Engagement. Performance. 3 Use of Non-GAAP Financial Measures and Key Performance Indicators To supplement our Consolidated Financial Statements presented in accordance with GAAP, we use certain non-GAAP financial measures, such as operating net income available to common shareholders, operating earnings per diluted common share, return on average tangible equity, return on average tangible common equity, return on average tangible assets, tangible book value per common share, the ratio of tangible common equity to tangible assets, pre-provision net revenue (reported), operating pre-provision net revenue, efficiency ratio, operating revenue, operating non-interest income and net interest margin (FTE) to provide information useful to investors in understanding our operating performance and trends, and to facilitate comparisons with the performance of our peers. Management uses these measures internally to assess and better understand our underlying business performance and trends related to core business activities. The non-GAAP financial measures and key performance indicators we use may differ from the non-GAAP financial measures and key performance indicators other financial institutions use to assess their performance and trends. These non-GAAP financial measures should be viewed as supplemental in nature, and not as a substitute for, or superior to, our reported results prepared in accordance with GAAP. Reconciliations of non-GAAP operating measures to the most directly comparable GAAP financial measures are included in the appendix to this presentation. Management believes certain items (e.g., FDIC special assessment) are not organic to running our operations and facilities. These items are considered significant items impacting earnings as they are deemed to be outside of ordinary banking activities. These costs are specific to each individual transaction and may vary significantly based on the size and complexity of the transaction. To facilitate peer comparisons of net interest margin and efficiency ratio, we use net interest income on a taxable-equivalent basis in calculating net interest margin by increasing the interest income earned on tax-exempt assets (loans and investments) to make it fully equivalent to interest income earned on taxable investments (this adjustment is not permitted under GAAP). Taxable-equivalent amounts for 2025 and 2024 were calculated using a federal statutory income tax rate of 21%.
