FOR IMMEDIATE RELEASE

S&T Bancorp, Inc. Announces First Quarter 2023 Net Income

INDIANA, Pa. - April 20, 2023 - S&T Bancorp, Inc. (S&T) (NASDAQ: STBA), the holding company for S&T Bank, announced net income of $39.8 million, or $1.02 per diluted share, for the first quarter of 2023 compared to net income of $40.3 million, or $1.03 per diluted share, for the fourth quarter of 2022 and net income of $29.1 million, or $0.74 per diluted share, for the first quarter of 2022.

First Quarter of 2023 Highlights:

•Solid return metrics with return on average assets (ROA) of 1.77%, return on average equity (ROE) of 13.38% and return on average tangible equity (ROTE) (non-GAAP) of 19.61% compared to ROA of 1.78%, ROE of 13.68% and ROTE (non-GAAP) of 20.36% for the fourth quarter of 2022.

•Pre-provision net revenue to average assets (PPNR) (non-GAAP) of 2.23% compared to 2.36% for the fourth quarter of 2022.

•Net interest margin (NIM) (FTE) (non-GAAP) was relatively unchanged at 4.32% compared to 4.33% in the fourth quarter of 2022.             

•Total portfolio loans increased $67.1 million, or 3.8% annualized, compared to December 31, 2022.

•Deposits decreased $66.9 million, or 3.8% annualized, compared to December 31, 2022 with a decline in January, stability in February and growth in March.

•Net recovery of $5.1 million, or 0.29% of average loans (annualized), primarily related to a $9.3 million recovery from a customer fraud in 2020.

"We delivered solid net interest margin and return metrics for the first quarter. Our balance sheet is a source of strength with a stable, well-diversified deposit base and a strong capital position," said Chris McComish, chief executive officer. "As the economic landscape continues to evolve, we remain committed to our purpose of People-Forward Banking. I am proud of the results from our team's proactive customer outreach and engagement during the quarter."

Net Interest Income

Net interest income was $88.8 million for the first quarter of 2023 compared to $89.1 million for the fourth quarter of 2022. The decrease of $0.3 million in net interest income was driven by higher funding costs and two fewer days in the first quarter, partially offset by higher yields on interest-earning assets. Net interest margin on a fully taxable equivalent basis (NIM) (FTE) (non-GAAP) decreased 1 basis point to 4.32% compared to 4.33% in the prior quarter. The yield on total average loans increased 43 basis points to 5.81% compared to 5.38% in the fourth quarter of 2022 due to higher interest rates. Total interest-bearing deposit costs increased 37 basis points to

S&T Earnings Release - 2

1.30% compared to 0.93% in the fourth quarter of 2022. Higher interest-bearing deposit costs primarily related to a change in the mix of deposits with higher balances in certificates of deposit. Average certificate of deposit balances increased $110.7 million compared to the fourth quarter of 2022. Total borrowing costs increased 53 basis points to 5.13% compared to 4.60% in the fourth quarter of 2022. Average borrowings increased $303.2 million to $520.8 million compared to $217.6 million in the fourth quarter of 2022 due to loan growth and deposit balance declines.

Asset Quality

Net loan recoveries were $5.1 million for the first quarter of 2023 compared to net loan charge-offs of $0.9 million in the fourth quarter of 2022. The net recovery primarily related to a $9.3 million recovery from a customer fraud in 2020. Total charge-offs of $4.5 million primarily related to a $3.4 million charge from a strategic exit of a C&I credit through a note sale . Total nonperforming assets increased $5.6 million to $27.7 million at March 31, 2023 compared to $22.1 million at December 31, 2022. Nonperforming assets to total loans plus OREO increased 7 basis points to 0.38% at March 31, 2023 compared to 0.31% at December 31, 2022. The provision for credit losses was $0.9 million for the first quarter of 2023 compared to $3.2 million in the fourth quarter of 2022. The allowance for credit losses was 1.49% of total portfolio loans as of March 31, 2023 compared to 1.41% at December 31, 2022. The increase in the allowance for credit losses related to a $4.2 million specific reserve and additional qualitative reserve due to the uncertainty in the macroeconomic environment.

Noninterest Income and Expense

Noninterest income decreased $2.4 million to $13.2 million in the first quarter of 2023 compared to $15.6 million in the fourth quarter of 2022. The decrease mainly related to a decline in other income of $2.1 million primarily related to a net gain on the sale of OREO of $2.0 million in the fourth quarter of 2022. Noninterest expense was $51.7 million compared to $51.3 million in the fourth quarter of 2022. FDIC insurance increased $0.6 million primarily related to an increase in the assessment rate schedule effective January 1, 2023. Marketing increased $0.5 million due to the timing of various marketing promotions. Salaries and employee benefits decreased $0.4 million due to lower incentives and pension costs.

Financial Condition

Total assets were $9.2 billion at March 31, 2023 compared to $9.1 billion at December 31, 2022. Total portfolio loans increased by $67.1 million, or 3.8% annualized, compared to December 31, 2022. The consumer loan portfolio increased $65.3 million with growth in residential mortgages of $72.7 million compared to December 31, 2022.

Total deposits decreased $66.9 million, or 3.8% annualized, compared to December 31, 2022. Deposit balances declined early in the quarter for the month of January followed by stability in February and growth in March. Certificates of deposit increased $240.6 million compared to December 31, 2022 mainly due to migration from other deposit categories. Our deposit base is stable and well-diversified with 59% personal deposits and 41% business deposits. Total borrowings increased $124.9 million to $564.1 million compared to December 31, 2022 related to loan growth and deposit declines.

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; cyber-security concerns; rapid technological developments and changes; operational risks or risk management failures by us or critical third parties, including fraud risk; our ability to manage our reputational 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; the transition from LIBOR as a reference rate; 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 may adversely affect our business, results of operations, liquidity and stock price; 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 employees; general economic or business conditions, including the strength of regional economic conditions in our market area; environmental, social and governance 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.

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, 2022, 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 of average tangible shareholder's equity, PPNR to average assets, efficiency ratio, 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.

PPNR / Average Assets (non-GAAP)	2.23	%	2.36	%	1.52	%
Pre-provision net revenue to average assets is income before taxes adjusted to exclude provision for credit losses. We believe this to be a preferred industry measurement to help evaluate our ability to fund credit losses or build capital.
(4) Efficiency Ratio (non-GAAP)
Noninterest expense	$51,699		$51,275		$47,414
Net interest income per consolidated statements of net income	88,791		89,058		67,733

Efficiency ratio (non-GAAP)	50.42	%	48.73	%	56.82	%
The efficiency ratio is noninterest expense divided by noninterest income plus net interest income, on an FTE basis (non-GAAP), which ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice.

Net interest margin (FTE) (non-GAAP)	4.32	%	4.33	%	3.16	%
The interest income on interest-earning assets, net interest income and net interest margin are presented on an FTE basis (non-GAAP). The FTE basis (non-GAAP) adjusts for the tax benefit of income on certain tax-exempt loans and securities and the dividend-received deduction for equity securities using the federal statutory tax rate of 21 percent for each period. We believe this to be the preferred industry measurement of net interest income that provides a relevant comparison between taxable and non-taxable sources of interest income.

First Quarter 2023 Earnings Supplement

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; cyber-security concerns; rapid technological developments and changes; operational risks or risk management failures by us or critical third parties, including fraud risk; our ability to manage our reputational 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; the transition from LIBOR as a reference rate; 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 may adversely affect our business, results of operations, liquidity and stock price; 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 employees; general economic or business conditions, including the strength of regional economic conditions in our market area; environmental, social and governance 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. 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, 2022, 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 the traditional measures presented in accordance with Generally Accepted Accounting Principles (GAAP), S&T management uses and this presentation contains or references certain non-GAAP financial measures, such as net interest income on a fully taxable equivalent basis. S&T believes these non-GAAP financial measures provide information useful to investors in understanding our underlying business, operational performance and performance trends which facilitate comparisons with the performance of others in the financial services industry. Although S&T believes that these non-GAAP financial measures enhance investors’ understanding of S&T’s business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP or considered to be more important than financial results determined in accordance with GAAP, nor are they necessary 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 in Exhibit 99.1 of Form 8-K for S&T Bancorp, Inc. and subsidiaries. 2

The FTE basis (non-GAAP) adjusts for the tax benefit of income on certain tax-exempt loans and securities and the dividend-received deduction for equity securities using the federal statutory tax rate of 21 percent for each period. We believe this to be the preferred industry measurement of net interest income that provides a relevant comparison between taxable and non-taxable sources of interest income.
