**F.N.B. Corporation Reports Third Quarter 2025 Earnings**

*Earnings per Diluted Common Share of $0.41, a 37% Increase From the Prior Year (21% on an Operating Basis (non-GAAP)), Driven By Record Revenue of $457 Million with Tangible Book Value Per Common Share (non-GAAP) Year-over-Year growth of 11%* 

**PITTSBURGH, PA – October 16, 2025** – F.N.B. Corporation (NYSE: FNB) reported earnings for the third quarter of 2025 with net income available to common shareholders of $149.5 million, or $0.41 per diluted common share. Comparatively, third quarter of 2024 net income available to common shareholders totaled $110.1 million, or $0.30 per diluted common share, and second quarter of 2025 net income available to common shareholders totaled $130.7 million, or $0.36 per diluted common share.

On an operating basis, third quarter of 2025 earnings per diluted common share (non-GAAP) was $0.41, excluding ($2.3) million (pre-tax) of significant items impacting earnings. By comparison, the third quarter of 2024 was $0.34 of earnings per diluted common share (non-GAAP) on an operating basis, excluding $0.04 of earnings per diluted common share (non-GAAP) of significant items impacting earnings, and the second quarter of 2025 was $0.36 of earnings per diluted common share (non-GAAP) with no significant items impacting earnings.

"F.N.B. Corporation reported record earnings per diluted common share of $0.41, a 37% increase from the year-ago quarter and 14% increase from the prior quarter, with revenue of $457 million principally driven by growth in net interest income, margin expansion and record non-interest income. Pre-provision net revenue (non-GAAP) grew 11% linked-quarter contributing to positive operating leverage and a peer-leading efficiency ratio (non-GAAP) of 52%," said F.N.B. Corporation Chairman, President and Chief Executive Officer, Vincent J. Delie, Jr. "Our growing profitability further strengthened capital levels to all-time highs with a CET1 regulatory capital ratio of 11% (estimated), tangible book value per share (non-GAAP) growth of 11% year-over-year and a return on tangible common equity ratio (non-GAAP) of 15%. FNB's performance is supported by our consistent underwriting standards and proactive credit risk management actions, which led to continued solid credit results for the quarter, and by our technology investments. Our investments in digital capabilities, data analytics and Artificial Intelligence enable us to broaden household penetration and increasingly serve as the primary bank for new and existing consumer and commercial clients."

**Third Quarter 2025 Highlights**

*(All comparisons refer to the third quarter of 2024, except as noted)*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Average loans and leases totaled $34.8 billion, an increase of $1.0 billion, or 3.0%, primarily driven by consumer loan growth of $994.7 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Average deposits totaled $37.9 billion, an increase of $2.3 billion, or 6.4%, as the growth in average interest-bearing demand deposits of $2.1 billion, average time deposits of $261.3 million and average non-interest-bearing demand deposits of $38.2 million more than offset the decline in average savings deposits of $155.9 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On a linked-quarter basis, average loans and leases increased 3.6% annualized and average deposits increased 8.2% annualized.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The loan-to-deposit ratio was 91% at September 30, 2025, a slight improvement compared to 92% at both June 30, 2025, and September 30, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net interest income totaled a record $359.3 million, an increase of $12.1 million, or 3.5%, linked-quarter, primarily due to growth in earning assets, lower cost of funds and the impact of one more day in the quarter.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Net interest margin (FTE) (non-GAAP) equaled 3.25%, an increase of 6 basis points from the second quarter of 2025, reflecting a 3 basis point improvement in the total yield on earning assets (non-GAAP) and a 3 basis point decline in the total cost of funds.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Non-interest income totaled a record $98.2 million, an increase of $7.2 million, or 7.9%, from the prior quarter, benefiting from our diversified business model and related revenue generation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pre-provision net revenue (non-GAAP) totaled $213.9 million, an 11.4% increase from the prior quarter, driven by continued strong non-interest income generation, growth in net interest income and well managed non-interest expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provision for credit losses was $24.0 million, a decrease of $1.6 million from the prior quarter, with net charge-offs of $19.7 million, or 0.22% annualized of total average loans, compared to $21.8 million, or 0.25% annualized, in the prior quarter. The ratio of non-performing loans and other real estate owned (OREO) to total loans and leases and OREO increased 3 basis points from the prior quarter to 0.37%, and total delinquency increased 3 basis points from the prior quarter to 0.65%. The allowance for credit losses (ACL) to total loans and leases remained stable at 1.25%. Overall, asset quality metrics remain at solid levels, reflecting continued proactive management of the loan portfolio.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Record capital levels with the Common Equity Tier 1 (CET1) regulatory capital ratio at 11.0% (estimated), compared to 10.4% at September 30, 2024, and 10.8% at June 30, 2025. The tangible common equity to tangible assets ratio (non-GAAP) equaled 8.7%, compared to 8.2% at September 30, 2024, and 8.5% at June 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tangible book value per common share (non-GAAP) of $11.48 increased $1.15, or 11.1%, compared to September 30, 2024, and $0.34, or 3.1%, compared to June 30, 2025. Accumulated other comprehensive income/loss (AOCI) reduced the tangible book value per common share (non-GAAP) by $0.22 as of September 30, 2025, primarily due to the impact of unrealized losses on Available-for-Sale (AFS) securities, compared to a reduction of $0.43 as of September 30, 2024, and $0.26 as of June 30, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During the third quarter of 2025, the Company repurchased $12 million, or 0.8 million shares, of common stock at a weighted average share price of $15.50 while maintaining capital above stated operating levels and supporting loan growth in the quarter.

Non-GAAP measures referenced in this release are used by management to measure performance in operating the business that management believes enhances investors' ability to better understand the underlying business performance and trends related to core business activities. Reconciliations of non-GAAP operating measures to the most directly comparable GAAP financial measures are included in the tables at the end of this release. For more information regarding our use of non-GAAP measures, please refer to the discussion herein under the caption, "Use of Non-GAAP Financial Measures and Key Performance Indicators."

**Third Quarter 2025 Results – Comparison to Prior-Year Quarter**

*(All comparisons refer to the third quarter of 2024, except as noted)*

Net interest income totaled $359.3 million, an increase of $35.9 million, or 11.1%, reflecting growth in earning assets and lower interest-bearing deposit costs, partially offset by lower yields on earning assets. The net interest margin (FTE) (non-GAAP) increased 17 basis points to 3.25%. The yield on earning assets (non-GAAP) decreased 15 basis points to 5.36%, driven by a 24 basis point decline in yields on loans to 5.79%, partially offset by a 41 basis point increase in yields on investment securities to 3.58%. Total cost of funds decreased 33 basis points to 2.23%, with a 42 basis point decrease in interest-bearing deposit costs to 2.66% and a 51 basis point decrease in total borrowing costs. The Federal Open Market Committee lowered the target federal funds rate by 125 basis points since August 2024.

Average loans and leases totaled $34.8 billion, an increase of $1.0 billion, or 3.0%, driven by growth of $994.7 million in consumer loans. Commercial leases increased $100.9 million, or 14.7%, driven by deepening customer relationships and increased activity in the manufacturing industry. Commercial real estate loans decreased $100.9 million, or 0.8%, while commercial and industrial loans increased slightly by $4.5 million, or 0.1%, as the growth in the North Carolina and Cleveland markets was offset by higher loan balance attrition from secondary market activity. The increase in average consumer loans included a $1.1 billion increase in residential mortgage loans largely due to the continued successful execution in key markets and long-standing strategy of serving the purchase market. Average indirect auto loans decreased $222.3 million, reflecting a sale of $431 million that closed in the third quarter of 2024, partially offset by new organic growth in the portfolio.

Average deposits totaled $37.9 billion, an increase of $2.3 billion, or 6.4%. The growth in average interest-bearing demand deposits of $2.1 billion, average time deposits of $261.3 million and average non-interest-bearing demand deposits of $38.2 million more than offset the decline in average savings deposits of $155.9 million as customers continued to migrate balances into higher-yielding products. The funding mix has slightly shifted compared to the year-ago quarter with non-interest-bearing demand deposits comprising 26% of total deposits at September 30, 2025, compared to 27% a year ago. The loan-to-deposit ratio improved to 91% at September 30, 2025, compared to 92% at September 30, 2024.

Non-interest income totaled a record $98.2 million, compared to $89.7 million. Mortgage banking operations income increased $3.6 million, or 65.8%, due to strong sold loan volumes, net positive fair value adjustments from pipeline hedging activity and a mortgage servicing rights (MSR) impairment of $2.8 million in the third quarter of 2024. Mortgage sold production increased 21% from the year-ago quarter. Capital markets income increased $1.7 million, or 27.1%, driven by record debt capital markets and international banking income, as well as contributions from customer swap activity, syndications, public finance and advisory services. Wealth Management revenues increased $1.5 million, or 8.0%, as securities commissions and fees and trust income increased 12.6% and 4.7%, respectively, through continued strong contributions across the geographic footprint. Other non-interest income increased $5.3 million, or 135.6%, primarily due to a $5.4 million recovery on an other asset previously written off as part of a 2017 acquisition.

------

Non-interest expense totaled $243.5 million, decreasing $5.9 million, or 2.4%. When adjusting for ($2.3) million<sup>1</sup> of significant items in the third quarter of 2025 and $15.3 million<sup>2</sup> of significant items in the third quarter of 2024, operating non-interest expense (non-GAAP) increased $11.6 million, or 5.0%. Salaries and employee benefits increased $5.5 million, or 4.4%, primarily reflecting strategic hiring, continued investments in our risk management infrastructure, and higher production-related compensation. Outside services increased $1.7 million, or 6.8%, due to higher volume-related technology and third-party costs. Other non-interest expense increased $3.7 million, or 17.4%, on an operating basis (non-GAAP) reflecting the impact of Community Uplift, a mortgage down payment assistance program that also includes commitments from our previously announced settlement agreement with the Department of Justice.

The ratio of non-performing loans and OREO to total loans and OREO decreased 2 basis points to 0.37%. Total delinquency decreased 14 basis points to 0.65%. Overall, asset quality metrics continue to remain at solid levels.

The provision for credit losses was $24.0 million, compared to $23.4 million. The third quarter of 2025 reflected net charge-offs of $19.7 million, or 0.22% annualized of total average loans, compared to $21.5 million, or 0.25% annualized, reflecting continued proactive management of the loan portfolio. The ACL was $437.3 million, an increase of $17.1 million, reflecting overall loan growth and a stable ratio of the ACL to total loans and leases at 1.25%.

The effective tax rate was 21.3%, compared to 21.4% in the third quarter of 2024.

The CET1 regulatory capital ratio was 11.0% (estimated) at September 30, 2025, and 10.4% at September 30, 2024. Tangible book value per common share (non-GAAP) was $11.48 at September 30, 2025, an increase of $1.15, or 11.1%, from $10.33 at September 30, 2024. AOCI reduced the current quarter tangible book value per common share (non-GAAP) by $0.22, compared to a reduction of $0.43 at the end of the year-ago quarter.

**Third Quarter 2025 Results – Comparison to Prior Quarter**

*(All comparisons refer to the second quarter of 2025, except as noted)*

Net interest income totaled $359.3 million, an increase of $12.1 million, or 3.5%, reflecting growth in earning assets, lower cost of funds and the impact of one more day in the quarter. The total yield on earning assets (non-GAAP) increased 3 basis points to 5.36%. The total cost of funds decreased 3 basis points to 2.23%, as the cost of interest-bearing deposits remained stable at 2.66% and total borrowing costs declined 6 basis points to 4.65%. Total average borrowings declined $423.7 million primarily due to the $350 million senior note offering that matured in August 2025 and the funding mix shift reflecting the growth in average deposits. The resulting net interest margin (FTE) (non-GAAP) was 3.25%, a 6 basis point increase from the prior quarter.

Average loans and leases totaled $34.8 billion, an increase of $311.8 million, or 3.6% annualized, as average consumer loans increased $431.2 million, or 13.0% annualized, and average commercial loans and leases decreased $119.4 million, or 2.2% annualized. The decrease in average commercial loans and leases included a decrease of $107.6 million in commercial real estate and $19.0 million in commercial and industrial loans reflecting elevated loan attrition in the secondary markets, partially offset by a $13.0 million increase in commercial leases. For consumer lending, average residential mortgages

<sup>1</sup> Third quarter 2025 non-interest expense significant items impacting earnings included a ($2.3) million (pre-tax) reduction in the estimated Federal Deposit Insurance Company (FDIC) special assessment related to the 2023 bank failures.

<sup>2</sup> Third quarter 2024 non-interest expense significant items impacting earnings included an $11.6 million (pre-tax) loss on an indirect auto loan sale and a $3.7 million (pre-tax) software impairment.

increased $384.4 million driven by continued seasonal growth in mortgage originations and average consumer home equity lending increased $45.7 million, or 12.9% annualized.

Average deposits totaled $37.9 billion, an increase of $766.5 million, due to organic growth in new and existing customer relationships. The increases were due to growth in average interest-bearing demand deposits of $375.2 million, average time deposits of $254.2 million, average non-interest-bearing deposit balances of $92.7 million and average savings deposit balances of $44.4 million. The mix of non-interest-bearing demand deposits to total deposits was stable at 26% for both September 30, 2025 and June 30, 2025. The loan-to-deposit ratio improved to 91% at September 30, 2025 compared to 92% at June 30, 2025.

Non-interest income totaled a record $98.2 million, an increase of $7.2 million, or 7.9%, from the prior quarter. Mortgage banking operations income increased $2.9 million, or 45.6%, primarily due to strong sold loan volumes. Capital markets income increased $1.0 million, or 14.2%, driven by record debt capital markets and international banking income, as well as contributions from customer swap activity, syndications, public finance and advisory services. Other non-interest income increased $3.2 million, or 53.3%, primarily due to a $5.4 million recovery on an other asset previously written off as part of a 2017 acquisition.

Non-interest expense totaled $243.5 million, a decrease of $2.7 million, or 1.1%, compared to the prior quarter. When adjusting for ($2.3) million<sup>3</sup> of significant items in the third quarter of 2025, operating non-interest expense (non-GAAP) decreased $0.4 million, or 0.2%. Salaries and employee benefits increased $1.7 million, or 1.3%, reflecting increased performance-related compensation while net occupancy and equipment decreased $2.5 million, or 5.2%, primarily due to lower fixed asset depreciation. The efficiency ratio (non-GAAP) totaled 52.4%, down from 54.8% in the prior quarter.

The ratio of non-performing loans and OREO to total loans and OREO increased 3 basis points to 0.37%, and delinquency increased 3 basis points to 0.65%. Overall, asset quality metrics continue to remain at solid levels. The provision for credit losses was $24.0 million, compared to $25.6 million. The third quarter of 2025 reflected net charge-offs of $19.7 million, or 0.22% annualized of total average loans, compared to $21.8 million, or 0.25% annualized, reflecting continued proactive management of the loan portfolio. The ACL was $437.3 million, an increase of $5.2 million, with the ratio of the ACL to total loans and leases stable at 1.25%.

**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, 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

<sup>3</sup> Third quarter 2025 non-interest expense significant items impacting earnings included a ($2.3) million (pre-tax) reduction in the estimated FDIC special assessment related to the 2023 bank failures.

------

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 later in this release under the heading "Reconciliations of Non-GAAP Financial Measures and Key Performance Indicators to GAAP."

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%.

**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," "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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the credit risk associated with the substantial amount of commercial loans and leases in our loan portfolio;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the volatility of the mortgage banking business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the impact of changes in interest rates on the value of our investment securities portfolios;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the risk associated with uninsured deposit account balances;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulatory limits on our ability to receive dividends from our subsidiaries and pay dividends to our shareholders;

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to recruit and retain qualified banking professionals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the financial soundness of other financial institutions and the impact of volatility in the banking sector on us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to continue to invest in technological improvements as they become appropriate or necessary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• any interruption in or breach in security of our information systems, or other cybersecurity risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks associated with reliance on third-party vendors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• risks associated with the use of models, estimations and assumptions in our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the effects of adverse weather events and public health emergencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the risks associated with acquiring other banks and financial services businesses, including integration into our existing operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in federal, state or local tax rules and regulations or interpretations, or accounting policies, standards and interpretations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the effects of climate change and related legislative and regulatory initiatives; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.
