FOR IMMEDIATE RELEASE

S&T Bancorp, Inc. Announces Second Quarter 2021 Net Income

Indiana, Pa. - July 22, 2021 - 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 $28.4 million, or $0.72 per diluted share, for the second quarter of 2021 compared to net income of $31.9 million, or $0.81 per diluted share, for the first quarter of 2021, and a net loss of ($33.1) million, or ($0.85) per diluted share, for the second quarter of 2020. A loss of $58.7 million was recognized during the second quarter of 2020 related to a customer fraud resulting from a check kiting scheme. This fraud loss reduced net income by $46.3 million, or $1.19 per diluted share, resulting in a net loss for the second quarter of 2020.

New Chief Executive Officer

Christopher J. McComish has been appointed as the company's chief executive officer, effective August 23, 2021. Chris McComish has over 30 years of financial service experience, providing executive leadership to consumer banking, commercial banking, and wealth management businesses. He has a strong track record of driving growth and transformation while enhancing both digital and human customer engagement. Most recently, Chris served as senior executive vice president of TCF Bank, leading all consumer banking lines of business as well as business banking and wealth management. Prior to TCF, he served as president and CEO of Scottrade Bank, the banking subsidiary of Scottrade Financial Services, Inc. In addition, he served as the head of personal banking and then as chief operating officer for personal and commercial banking at BMO Harris Bank. He began his career at Wachovia Bank, where he spent over 20 years in various regional and line of business leadership roles.

"I am honored to have the opportunity to partner with Chris to lead this great organization," said David Antolik, president and interim chief executive officer. "Chris's experience in executive leadership roles in banking combined with my 30 plus years of experience at S&T puts us in a position of strength to move our company forward."

Second Quarter of 2021 Highlights:

•Christopher McComish has been appointed as the chief executive officer, effective August 23, 2021.

•Return on average assets (ROA) of 1.21%, return on average equity (ROE) of 9.65%, return on average tangible equity (ROTE) (non-GAAP) of 14.41% and pre-tax pre-provision income to average assets (PTPP) (non-GAAP) of 1.61%.

•Net interest margin (FTE) (non-GAAP) decreased 31 basis points to 3.16% compared to 3.47% for the first quarter of 2021 primarily due to higher cash balances and a lower Paycheck Protection Program (PPP) contribution.

•Ex-PPP portfolio loans decreased $12.7 million and total portfolio loans decreased $175.8 million compared to March 31, 2021.

•Deposits increased $139.2 million to $8.0 billion at June 30, 2021 compared to March 31, 2021.

S&T Earnings Release -2

•The allowance for credit losses to total portfolio loans was 1.56% at June 30, 2021 compared to 1.60% at March 31, 2021.

•S&T's Board of Directors declared a $0.28 per share dividend which was consistent with the $0.28 per share dividend declared in the same period in the prior year.

"We continue to see positive signs of a recovery across all of our markets," said David Antolik. "Customer activity has increased substantially and our loan pipeline exceeds pre-pandemic levels making us optimistic about our growth prospects for the second half of 2021."

Net Interest Income

Net interest income decreased $2.4 million to $68.3 million for the second quarter of 2021 compared to $70.7 million for the first quarter of 2021. The decrease in net interest income was primarily due to a lower contribution from PPP and lower average loan balances ex-PPP. The PPP contribution decreased $1.7 million to $4.1 million for the second quarter of 2021 compared to $5.8 million in the first quarter of 2021. Average portfolio loans ex-PPP decreased $123.1 million compared to the first quarter of 2021. Net interest margin on a fully taxable equivalent basis (NIM) (FTE) (non-GAAP) decreased 31 basis points to 3.16% compared to 3.47% in the prior quarter. The decline in NIM (FTE) (non-GAAP) was due to a higher average cash balance (18 basis points), a lower PPP contribution (8 basis points) and lower loan yields (7 basis points). Partially offsetting these declines were lower costing liabilities which increased NIM (FTE) (Non-GAAP) by 5 basis points.

Asset Quality

The provision for credit losses decreased $0.5 million to $2.6 million for the second quarter of 2021 compared to $3.1 million in the first quarter of 2021. Net loan charge-offs were $7.5 million for the second quarter of 2021 compared to $5.8 million in the first quarter of 2021. Total nonperforming loans decreased $22.6 million to $112.6 million, or 1.61% of total loans, at June 30, 2021 compared to $135.2 million, or 1.88% of total loans at March 31, 2021. The allowance for credit losses was 1.56% of total portfolio loans as of June 30, 2021 compared to 1.60% at March 31, 2021. The allowance for credit losses was 1.64% of total portfolio ex-PPP loans at June 30, 2021 compared to 1.72% at March 31, 2021.

Noninterest Income and Expense

Noninterest income decreased $1.8 million to $15.4 million in the second quarter of 2021 compared to

$17.2 million in the first quarter of 2021. Mortgage banking income decreased $2.6 million due to a lower volume of loans sold and a decrease in the mortgage servicing rights valuation. Debit and credit card fees were strong with a $0.6 million increase compared to the prior quarter.

Noninterest expense increased $0.2 million to $45.8 million for the second quarter of 2021 compared to $45.6 million in the first quarter of 2021. Salaries and employee benefits increased $1.2 million due to annual merit increases and higher incentives.

Financial Condition

Total assets increased $166.9 million to $9.5 billion at June 30, 2021 compared to $9.3 billion at March 31, 2021. Cash increased $313.8 million to $985.3 million at June 30, 2021 compared to March 31, 2021 due to PPP forgiveness and an increase in deposits as a result of stimulus programs. Total portfolio loans decreased

$175.8 million compared to March 31, 2021. PPP originations were $31.1 million and PPP forgiveness was $194.2 million during the second quarter of 2021. Loan activity continues to be impacted by the pandemic. Deposits increased $139.2 million with a favorable mix of higher deposits across all categories except certificates of deposits. S&T continues to maintain a strong capital position with all capital ratios above the well-capitalized thresholds of federal bank regulatory agencies.

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, 2020, including Part I, Item 1A-"Risk Factors" and any of our subsequent filings with the SEC.

MEMBER FDIC Second Quarter 2021 Earnings Supplement


2 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, for example, our adoption of CECL; 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, including DNB, 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, 2020, 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.
