Fourth Quarter of 2021 Results (three months ended December 31, 2021)

Net Interest Income

Net interest income decreased $0.3 million to $68.4 million compared to $68.7 million in the third quarter of 2021. Net interest income, excluding PPP, increased by $0.8 million compared to the prior quarter. Net interest income related to PPP loans decreased $1.1 million to $3.1 million compared to $4.2 million in the prior quarter. Average PPP loans decreased by $92.7 million compared to the third quarter of 2021. Average loans, excluding PPP, increased $128.8 million compared to the prior quarter. Net interest margin on a fully taxable equivalent basis (FTE) (non-GAAP) decreased 2 basis points to 3.12% compared to 3.14% in the prior quarter. The decline in NIM (FTE) (non-GAAP) was primarily due to lower loan and security yields.

Asset Quality

Total nonperforming loans decreased by 40.4% or $45.0 million to $66.3 million, or 0.95% of total loans, at December 31, 2021 compared to $111.3 million, or 1.60% of total loans at September 30, 2021. The decrease in nonperforming loans primarily related to the return to performing status of $22.1 million of hotel loans and due to loan charge-offs. The provision for credit losses increased $3.7 million to $7.1 million for the fourth quarter of 2021 compared to $3.4 million in the third quarter of 2021. Net loan charge-offs were $17.7 million for the fourth quarter of 2021 compared to $3.6 million in the third quarter of 2021. Higher net charge-offs related to two commercial and industrial (C&I) relationships. A $10.3 million charge-off was taken on a relationship that moved to nonperforming during the third quarter of 2021 and had a specific reserve of $9.3 million at September 30, 2021. Additionally, a $5.6 million charge-off was taken related to a nonperforming relationship. The allowance for credit losses was 1.41% of total portfolio loans at December 31, 2021 compared to 1.55% at September 30, 2021.

Noninterest Income and Expense

Noninterest income increased $0.3 million to $16.1 million in the fourth quarter of 2021 compared to $15.8 million in the third quarter of 2021. The increase in noninterest income primarily related to higher commercial loan swap income of $0.4 million and other income of $0.7 million which was related to market value adjustments. Offsetting this increase was a decline in

S&T Earnings Release - 3

mortgage banking income of $0.6 million due to lower refinance activity compared to the third quarter of 2021. Noninterest expense increased $3.0 million to $50.2 million in the fourth quarter of 2021 compared to $47.2 million in the third quarter of 2021. Salaries and employee benefits increased $1.9 million compared to the prior quarter primarily due to higher incentives. Data processing increased $0.7 million due to increased activity and new products and services and marketing increased $0.5 million due to the timing of marketing initiatives.

Financial Condition

Total assets increased $52.5 million to $9.5 billion at December 31, 2021 compared to $9.4 billion at September 30, 2021. Portfolio loans, excluding PPP, increased $122.6 million, or 7.2% annualized, compared to September 30, 2021. Loan growth was in all categories except commercial construction. Commercial loans, excluding PPP, increased $75.3 million, or 5.7% annualized, which primarily consisted of C&I growth, excluding PPP, of $122.9 million, or 32.1% annualized. Consumer loans increased $47.3 million, or 12.1% annualized, which primarily consisted of home equity growth of $15.8 million, or 11.5% annualized, and residential mortgage growth of $12.0 million, or 5.4% annualized. PPP loans were $88.3 million at December 31, 2021 with $92.7 million of forgiveness during the fourth quarter of 2021. Securities increased $40.7 million compared to September 30, 2021 due to cash being redeployed to higher yielding assets. Total deposits increased $51.4 million mainly due to increases in noninterest-bearing demand of $96.3 million, savings of $35.3 million and money market of $25.3 million offset by a decrease in certificates of deposit of $113.2 million compared to September 30, 2021. S&T continues to maintain a strong capital position with all capital ratios above the well-capitalized thresholds of federal bank regulatory agencies.

Full Year 2021 Results (twelve months ended December 31, 2021)

Full year net income was a record $110.3 million, or $2.81 per diluted share, for the year ended December 31, 2021 compared to net income of $21.0 million, or $0.53 per diluted share, for 2020. Net income for 2020 was impacted by a customer fraud that reduced net income by $46.3 million, or $1.19 per diluted share.

Net interest income decreased $3.3 million compared to 2020 primarily due to the impact of a full year in a low interest rate environment. Net interest income was further impacted by the effects of the pandemic on loan growth throughout 2021 which resulted in a decrease in average loan balances of $325.8 million. Net interest margin (FTE) (non-GAAP) decreased 16 basis points to 3.22% compared to 3.38% for 2020.

Noninterest income increased $4.9 million compared to the prior year. Wealth management income increased $2.9 million due to customer growth and improved market conditions. Debit and credit card fees increased $2.9 million and service charges on deposit accounts increased $1.4 million due to increased customer activity. These were offset by lower commercial loan swap income of $3.6 million and mortgage banking income of $1.2 million. Noninterest expense increased $2.2 million compared to 2020. Salaries and employee benefits increased $10.1 million primarily due to higher payroll incentives. Data processing and information technology increased $1.2 million due to new products and services in 2021. These higher expenses were offset by decreases in marketing of $1.4 million and merger related expenses of $2.3 million. The efficiency ratio (non-GAAP) for 2021 was 55.05% compared to 53.86% for 2020.

The provision for credit losses decreased $115.2 million to $16.2 million for 2021 compared to $131.4 million for 2020. Excluding the customer fraud loss of $58.7 million, the provision was $72.7 million for 2020.The provision for credit losses

decreased significantly in 2021 due to lower net charge-offs and an improved outlook for the economy and our loan portfolio.

Fourth Quarter 2021 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, 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. 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
