FOR IMMEDIATE RELEASE

Indiana, Pa. - July 21, 2022 - S&T Bancorp, Inc. (S&T) (NASDAQ: STBA), the holding company for S&T Bank, with operations in five markets including Western Pennsylvania, Eastern Pennsylvania, Northeast Ohio, Central Ohio and Upstate New York, announced net income of $28.9 million, or $0.74 per diluted share, for the second quarter of 2022 compared to net income of $29.1 million, or $0.74 per diluted share, for the first quarter of 2022 and net income of $28.4 million, or $0.72 per diluted share, for the second quarter of 2021.

Second Quarter of 2022 Highlights:

•Return on average assets (ROA) of 1.25%, return on average equity (ROE) of 9.83% and return on average tangible equity (ROTE) (non-GAAP) of 14.63%.

•Pre-provision net revenue to average assets (PPNR) (non-GAAP) of 1.71%.

•Net interest income increased $7.5 million, or 11%, and NIM (FTE) (Non-GAAP) increased 40 basis points compared to the first quarter of 2022.

•Strong consumer loan growth of $111.7 million, or 27.5% annualized, compared to March 31, 2022.

•Nonperforming assets decreased $20.7 million, or 34.8%, compared to March 31, 2022.

•S&T’s Board of Directors approved a $0.30 per share dividend compared to $0.28 per share in the same period last year.

"Our performance was strong this quarter with significant growth in net interest income and net interest margin. We also saw significant improvement in our nonperforming assets with a decline of nearly 35% from the first quarter and a 66% decline from a year ago," said Chris McComish, chief executive officer. "We are extremely proud to be recently named by Forbes as a Best-In-State Bank especially on the heels of our recognition by J.D. Power as the highest in overall customer satisfaction with retail banking in the Pennsylvania region. Both awards are an honor and a true reflection of our dedicated employees and the trust our customers have placed in us to help meet their financial needs."

Net Interest Income

Net interest income increased $7.5 million, or 11%, to $75.2 million for the second quarter of 2022 compared to $67.7 million for the first quarter of 2022. The increase in net interest income was primarily due to higher interest rates in the second quarter. The yield on total average loans increased 34 basis points compared to the first quarter of 2022 while the cost of total interest-bearing deposits remained unchanged at 0.14%. Net interest margin on a fully taxable equivalent basis (NIM) (FTE) (non-GAAP) increased 40 basis points to 3.56% compared to 3.16% in the prior quarter.

S&T Earnings Release -2

Asset Quality

Total nonperforming assets decreased $20.7 million, or 34.8%, to $38.8 million at June 30, 2022. The decrease primarily related to the resolution of a $9.9 million commercial and industrial, or C&I, relationship and additional loan pay-offs. Significant progress has been made in reducing nonperforming assets over the past year with a reduction of $74.9 million, or 65.9%, since June 30, 2021. Nonperforming assets to total loans plus other real estate owned, or OREO, decreased 30 basis points to 0.55% at June 30, 2022 compared to 0.85% at

March 31, 2022 and 1.62% at June 30, 2021. Net loan charge-offs were $3.0 million for the second quarter of 2022 compared to net loan recoveries of $2.0 million in the first quarter of 2022. Gross loan charge-offs of $7.7 million were offset by recoveries of $4.7 million during the second quarter of 2022. The C&I relationship previously mentioned resulted in a $5.5 million charge-off which was offset by a $3.9 million C&I recovery from a relationship that was charged off in 2019. The provision for credit losses was $3.2 million for the second quarter of 2022 compared to negative $0.5 million in the first quarter of 2022. The negative provision in the first quarter of 2022 was mainly due to the net recovery of $2.0 million. The allowance for credit losses was 1.39% of total portfolio loans as of June 30, 2022 compared to 1.43% at March 31, 2022.

Noninterest Income and Expense

Noninterest income decreased $2.6 million to $12.6 million in the second quarter of 2022 compared to $15.2 million in the first quarter of 2022. Other income decreased $1.9 million primarily related to the decline in the fair value of the assets in a nonqualified benefit plan and a $0.5 million gain on sale of OREO in the first quarter of 2022. Mortgage banking income decreased $0.5 million due to a shift in the volume of loans sold to loans held in the portfolio. Noninterest expense increased $1.0 million to $48.4 million for the second quarter of 2022 compared to $47.4 million in the first quarter of 2022 mainly due to an increase of $1.1 million in salaries and employee benefits related to higher incentives and medical expense offset by a decline in the fair value of the liability in a nonqualified benefit plan. Professional services and legal increased $0.4 million related to various consulting engagements during the second quarter of 2022.

Financial Condition

Total assets were $9.1 billion at June 30, 2022 compared to $9.4 billion at March 31, 2022. The decrease in total assets related to a $479.1 million decline in cash balances which was mainly due to a decrease in total deposits and an increase in loans. Total portfolio loans excluding, Paycheck Protection Program, or PPP, increased by $107.2 million, or 6.2% annualized, compared to March 31, 2022. The consumer loan portfolio grew $111.7 million, or 27.5% annualized, with strong growth in both residential mortgages and home equity compared to

March 31, 2022. Noninterest-bearing demand deposits were stable at $2.7 billion compared to March 31, 2022. Interest-bearing deposits declined $344.7 million compared to March 31, 2022. The decline in interest-bearing deposits was concentrated in higher balance, rate sensitive customer accounts.

During the second quarter of 2022, 151,220 common shares were repurchased at a total cost of $4.2 million, or an average of $27.46 per share. S&T continues to maintain a strong regulatory capital position with all capital ratios above the well-capitalized thresholds of federal bank regulatory agencies.

Dividend

S&T's Board of Directors approved a $0.30 per share cash dividend on July 18, 2022. This dividend compares to a $0.28 per share dividend declared in the same period in the prior year. The dividend is payable August 18, 2022 to shareholders of record on August 4, 2022.

including the ultimate impact of the pandemic on the economy generally and on our operations; our participation in the Paycheck Protection Program; 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, 2021, 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.

Second Quarter 2022 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; 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 including a prolonged period of low interest rates, 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; changes in accounting policies, practices, or guidance; legislation affecting the financial services industry as a whole, and S&T, in particular; 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; our ability to successfully manage our CEO transition; general economic or business conditions, including the strength of regional economic conditions in our market area; the duration and severity of the coronavirus (“COVID-19”) pandemic, both in our principal area of operations and nationally, including the ultimate impact of the pandemic on the economy generally and on our operations; our participation in the Paycheck Protection Program; 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, 2021, 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 results of operations 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 financial measures provide information useful to investors in understanding our operational performance and business 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. 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
