**INDIANA, Pa.,** - **April 23, 2026** – S&T Bancorp, Inc. (S&T) (NASDAQ: STBA), the holding company for S&T Bank, announced net income of $35.1 million for the first quarter of 2026 compared to $34.0 million for the fourth quarter of 2025 and $33.4 million for the first quarter of 2025. Diluted earnings per share was $0.94 for the first quarter of 2026, an increase of $0.05, or 5.6%, compared to $0.89 for the fourth quarter of 2025 and an increase of $0.07, or 8.0%, compared to $0.87 for the first quarter of 2025.

**First Quarter of 2026 Highlights**:

**•** Strong return metrics with return on average assets (ROA) of 1.44%, return on average equity (ROE) of 9.77% and return on average tangible shareholders' equity (ROTE) (non-GAAP) of 13.22% compared to ROA of 1.37%, ROE of 9.13% and ROTE (non-GAAP) of 12.30% for the fourth quarter of 2025.

**•** Pre-provision net revenue to average assets (PPNR) (non-GAAP) was 1.87% compared to 1.95% for the fourth quarter of 2025.

• Net interest margin on a fully taxable equivalent basis (NIM) (FTE) (non-GAAP) remains strong at 3.92% compared to 3.99% in the fourth quarter of 2025.

• Total deposits increased $226.4 million, or 11.5% annualized, with customer deposit growth of $306.5 million, or 16.0% annualized, offset by lower brokered deposits of $80.1 million compared to December 31, 2025.

• Total portfolio loans decreased $112.6 million compared to December 31, 2025.

• Net charge-offs were $1.7 million, or 0.09% of average loans, compared to net charge-offs of $11.0 million, or 0.54% of average loans, in the fourth quarter of 2025.

• Nonperforming assets (NPAs) decreased $5.7 million to $49.9 million, or 0.63% of total loans plus other real estate owned (OREO), compared to $55.6 million, or 0.69%, at December 31, 2025.

• Share repurchases of 1,146,100 common shares for $49.6 million.

2025 and an interest recovery on a previously charged-off loan that occurred in the fourth quarter of 2025. NIM (FTE) (non-GAAP) declined 7 basis points to 3.92% compared to 3.99% in the prior quarter. Excluding a 4 basis point benefit from the interest recovery in the prior quarter, NIM (FTE) (non-GAAP) was relatively stable. Average interest-earning assets increased $57.0 million to $9.2 billion in the first quarter of 2026 compared to $9.1 billion in the fourth quarter of 2025. The yield on average interest-earning assets decreased 14 basis points to 5.60% compared to 5.74% in the fourth quarter of 2025 primarily due to a decline in interest rates on loans. Total interest-bearing liability costs decreased 12 basis points to 2.54% compared to 2.66% in the fourth quarter of 2025 mainly due to lower deposit costs and a reduction in higher-cost brokered deposits and borrowings. Average borrowings decreased $45.1 million to $174.5 million and average brokered deposits decreased $22.1 million to $170.1 million in the first quarter of 2026 compared to $219.6 million and $192.2 million in the fourth quarter of 2025.

**Asset Quality**

The allowance for credit losses, or ACL, was $93.3 million, or 1.17% of total portfolio loans, at March 31, 2026 compared to $93.2 million, or 1.15%, at December 31, 2025. The provision for credit losses was $1.3 million for the first quarter of 2026 compared to $5.7 million in the fourth quarter of 2025. The decrease in the provision for credit losses was primarily related to a decrease in net loan charge-offs. Net loan charge-offs were $1.7 million, or 0.09% of average loans, compared to $11.0 million, or 0.54% of average loans, in the fourth quarter of 2025. NPAs decreased $5.7 million to $49.9 million, or 0.63% of total loans plus OREO, compared to $55.6 million, or 0.69%, at December 31, 2025. Total NPAs remain at a manageable level.

**Noninterest Income and Expense**

Noninterest income decreased $0.7 million to $13.6 million in the first quarter of 2026 compared to $14.3 million in the fourth quarter of 2025. Customer activity was seasonally slower in the first quarter of 2026 resulting in lower debit and credit card fees compared to the fourth quarter of 2025. Noninterest expense decreased $0.5 million to $56.7 million compared to $57.2 million in the fourth quarter of 2025. The decrease primarily related to a $1.3 million decrease in salaries and benefits related to lower salaries and medical costs compared to the prior quarter.

**Financial Condition** 

Total assets were $9.9 billion at both March 31, 2026 and December 31, 2025. Cash and due from banks increased $175.6 million related to a significant increase in deposits and a decline in loans compared to December 31, 2025. Total portfolio loans decreased $112.6 million compared to December 31, 2025. The decline in loans related to lower fundings, reduced utilization rates and higher commercial real estate payoffs. The commercial loan portfolio decreased $79.0 million with declines in commercial real estate of $94.7 million and commercial and industrial of $8.3 million, offset by an increase in commercial construction of $23.9 million compared to December 31, 2025. The consumer loan portfolio decreased $33.6 million primarily due to declines in residential mortgage of $20.6 million, consumer construction of $8.9 million and installment and other consumer of $7.3 million, offset by an increase in home equity of $3.3 million compared to December 31, 2025. Total deposits increased $226.4 million, or 11.5% annualized, with customer deposit growth of $306.5 million, or 16.0% annualized, offset by lower brokered deposits of $80.1 million compared to December 31, 2025. Customer deposit growth reflected increases in core relationships but also included both temporary commercial customer funds and seasonal inflows related to consumer tax refunds. Noninterest bearing deposits increased $112.8 million, money market increased $67.8 million, savings increased $21.1 million and certificates of deposit increased $30.7 million, offset by a decrease in interest-bearing demand of $6.0 million compared to December 31, 2025. The increase in money market of $67.8 million is net of a decline in brokered money market of

$80.1 million compared to December 31, 2025. Total borrowings decreased $115.0 million to $150.3 million compared to $265.3 million at December 31, 2025 primarily related to deposit growth.

**Capital**

During the first quarter of 2026, 1,146,100 shares were repurchased at an average price of $43.30 per share for $49.6 million. Total share repurchases for both the fourth quarter of 2025 and the first quarter of 2026 were 2,094,370 shares at an average price of $40.99 per share totaling $85.8 million. The remaining capacity under the existing share repurchase program was $50.4 million at March 31, 2026.

S&T continues to maintain a strong regulatory capital position with all capital ratios above the well-capitalized thresholds of federal bank regulatory agencies.

**Forward-Looking Statements**

This information contains or incorporates statements that we believe are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to our financial condition, results of operations, plans, objectives, outlook for earnings, revenues, expenses, capital and liquidity levels and ratios, asset levels, asset quality, financial position and other matters regarding or affecting S&T and its future business and operations. Forward-looking statements are typically identified by words or phrases such as "will likely result," "expect," "anticipate," "estimate," "forecast," "project," "intend," "believe," "assume," "strategy," "trend," "plan," "outlook," "outcome," "continue," "remain," "potential," "opportunity," "comfortable," "current," "position," "maintain," "sustain," "seek," "achieve" and variations of such words and similar expressions, or future or conditional verbs such as "will," "would," "should," "could" or "may." Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. The matters discussed in these forward-looking statements are subject to various risks, uncertainties and other factors that could cause actual results and trends to differ materially from those made, projected or implied in or by the forward-looking statements depending on a variety of uncertainties or other factors including, but not limited to: credit losses and the credit risk of our commercial and consumer loan products; changes in the level of charge-offs and changes in estimates of the adequacy of the allowance for credit losses, or ACL; cybersecurity concerns; rapid technological developments and changes, including the use of artificial intelligence and digital assets; operational risks or risk management failures by us or critical third parties, including fraud risk; our ability to manage our brand risks; sensitivity to the interest rate environment, a rapid increase in interest rates or a change in the shape of the yield curve; a change in spreads on interest-earning assets and interest-bearing liabilities; regulatory supervision and oversight, including changes in regulatory capital requirements and our

ability to address those requirements; unanticipated changes in our liquidity position; unanticipated changes in regulatory and governmental policies impacting interest rates and financial markets; changes in accounting policies, practices or guidance; legislation affecting the financial services industry as a whole, and S&T, in particular; developments affecting the industry and the soundness of financial institutions and further disruption to the economy and U.S. banking system; the outcome of pending and future litigation and governmental proceedings; increasing price and product/service competition; the ability to continue to introduce competitive new products and services on a timely, cost-effective basis; managing our internal growth and acquisitions; the possibility that the anticipated benefits from acquisitions cannot be fully realized in a timely manner or at all, or that integrating the acquired operations will be more difficult, disruptive or costly than anticipated; containing costs and expenses; reliance on significant customer relationships; an interruption or cessation of an important service by a third-party provider; our ability to attract and retain talented executives and other employees; general economic or business conditions, including the strength of regional economic conditions in our market area; ESG practices and disclosures, including climate change, hiring practices, the diversity of the work force and racial and social justice issues; deterioration of the housing market and reduced demand for mortgages; deterioration in the overall macroeconomic conditions or the state of the banking industry that could warrant further analysis of the carrying value of goodwill and could result in an adjustment to its carrying value resulting in a non-cash charge to net income; the stability of our core deposit base and access to contingency funding; re-emergence of turbulence in significant portions of the global financial and real estate markets that could impact our performance, both directly, by affecting our revenues and the value of our assets and liabilities, and indirectly, by affecting the economy generally and access to capital in the amounts, at the times and on the terms required to support our future businesses and geopolitical tensions and conflicts between nations.

Many of these factors, as well as other factors, are described in our Annual Report on Form 10-K for the year ended December 31, 2025, including Part I, Item 1A-"Risk Factors" and any of our subsequent filings with the SEC. Forward-looking statements are based on beliefs and assumptions using information available at the time the statements are made. We caution you not to unduly rely on forward-looking statements because the assumptions, beliefs, expectations and projections about future events may, and often do, differ materially from actual results. Any forward-looking statement speaks only as to the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect developments occurring after the statement is made.

**Non-GAAP Financial Measures**

In addition to traditional measures presented in accordance with GAAP, our management uses, and this information contains or references, certain non-GAAP financial measures, such as tangible book value, return on average tangible shareholder's equity, PPNR to average assets, efficiency ratio on an FTE basis, tangible common equity to tangible assets and net interest margin on an FTE basis. We believe these non-GAAP financial measures provide information useful to investors in understanding our underlying operational performance and our business and performance trends as they facilitate comparisons with the performance of other companies in the financial services industry. Although we believe that these non-GAAP financial measures enhance investors' understanding of our business and performance, these non-GAAP financial measures should not be considered alternatives to GAAP or considered to be more important than financial results determined in accordance with GAAP, nor are they necessarily comparable with non-GAAP measures which may be presented by other companies. See Definitions and Reconciliation of GAAP to Non-GAAP Financial Measures for more information related to these financial measures.

Forward Looking Statements and Risk Factors This information contains or incorporates statements that we believe are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to our financial condition, results of operations, plans, objectives, outlook for earnings, revenues, expenses, capital and liquidity levels and ratios, asset levels, asset quality, financial position and other matters regarding or affecting S&T and its future business and operations. Forward-looking statements are typically identified by words or phrases such as "will likely result," "expect," "anticipate," "estimate," "forecast," "project," "intend," "believe," "assume," "strategy," "trend," "plan," "outlook," "outcome," "continue," "remain," "potential," "opportunity," "comfortable," "current," "position," "maintain," "sustain," "seek," "achieve" and variations of such words and similar expressions, or future or conditional verbs such as "will," "would," "should," "could" or "may." Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. The matters discussed in these forward-looking statements are subject to various risks, uncertainties and other factors that could cause actual results and trends to differ materially from those made, projected or implied in or by the forward-looking statements depending on a variety of uncertainties or other factors including, but not limited to: credit losses and the credit risk of our commercial and consumer loan products; changes in the level of charge- offs and changes in estimates of the adequacy of the allowance for credit losses, or ACL; cybersecurity concerns; rapid technological developments and changes, including the use of artificial intelligence and digital assets; operational risks or risk management failures by us or critical third parties, including fraud risk; our ability to manage our brand risks; sensitivity to the interest rate environment, a rapid increase in interest rates or a change in the shape of the yield curve; a change in spreads on interest-earning assets and interest-bearing liabilities; regulatory supervision and oversight, including changes in regulatory capital requirements and our ability to address those requirements; unanticipated changes in our liquidity position; unanticipated changes in regulatory and governmental policies impacting interest rates and financial markets; changes in accounting policies, practices or guidance; legislation affecting the financial services industry as a whole, and S&T, in particular; developments affecting the industry and the soundness of financial institutions and further disruption to the economy and U.S. banking system; the outcome of pending and future litigation and governmental proceedings; increasing price and product/service competition; the ability to continue to introduce competitive new products and services on a timely, cost-effective basis; managing our internal growth and acquisitions; the possibility that the anticipated benefits from acquisitions cannot be fully realized in a timely manner or at all, or that integrating the acquired operations will be more difficult, disruptive or costly than anticipated; containing costs and expenses; reliance on significant customer relationships; an interruption or cessation of an important service by a third-party provider; our ability to attract and retain talented executives and other employees; general economic or business conditions, including the strength of regional economic conditions in our market area; ESG practices and disclosures, including climate change, hiring practices, the diversity of the work force and racial and social justice issues; deterioration of the housing market and reduced demand for mortgages; deterioration in the overall macroeconomic conditions or the state of the banking industry that could warrant further analysis of the carrying value of goodwill and could result in an adjustment to its carrying value resulting in a non-cash charge to net income; the stability of our core deposit base and access to contingency funding; re-emergence of turbulence in significant portions of the global financial and real estate markets that could impact our performance, both directly, by affecting our revenues and the value of our assets and liabilities, and indirectly, by affecting the economy generally and access to capital in the amounts, at the times and on the terms required to support our future businesses and geopolitical tensions and conflicts between nations. Many of these factors, as well as other factors, are described in our Annual Report on Form 10-K for the year ended December 31, 2025, including Part I, Item 1A-"Risk Factors" and any of our subsequent filings with the SEC. Forward-looking statements are based on beliefs and assumptions using information available at the time the statements are made. We caution you not to unduly rely on forward-looking statements because the assumptions, beliefs, expectations and projections about future events may, and often do, differ materially from actual results. Any forward-looking statement speaks only as to the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect developments occurring after the statement is made. Non-GAAP Financial Measures In addition to traditional measures presented in accordance with GAAP, our management uses, and this information contains or references, certain non-GAAP financial measures, such as tangible book value, return on average tangible shareholder's equity, PPNR to average assets, efficiency ratio on an FTE basis, tangible common equity to tangible assets and net interest margin on an FTE basis. We believe these non-GAAP financial measures provide information useful to investors in understanding our underlying operational performance and our business and performance trends as they facilitate comparisons with the performance of other companies in the financial services industry. Although we believe that these non-GAAP financial measures enhance investors' understanding of our business and performance, these non-GAAP financial measures should not be considered alternatives to GAAP or considered to be more important than financial results determined in accordance with GAAP, nor are they necessarily comparable with non-GAAP measures which may be presented by other companies. The non-GAAP financial measures contained within this presentation should be read in conjunction with the audited financial statements and analysis as presented in the Annual Report on Form 10-K as well as the unaudited financial statements and analyses as presented in the respective Quarterly Reports on Form 10-Q and in Exhibit 99.1 of Form 8-K for S&T Bancorp, Inc. and subsidiaries. 2
