Fourth Quarter of 2022 Results (three months ended December 31, 2022)

Net Interest Income

Net interest income increased $5.3 million, or 6.3%, to $89.1 million compared to $83.8 million in the third quarter of 2022. The increase in net interest income was primarily due to higher interest rates in the fourth quarter. The yield on total average loans increased 69 basis points to 5.38% compared to 4.69% in the third quarter of 2022. Total interest-bearing deposit costs increased 50 basis points to 0.93% compared to 0.43% in the third quarter of 2022. Average interest-bearing deposit balances declined $129.7 million compared to the prior quarter due to the competitive market driven by rising interest rates. Total borrowing costs increased 108 basis points to 4.60% compared to 3.52% in the third quarter of 2022. Average borrowings increased $122.8 million to $217.6 million compared to $94.8 million in the third quarter. Net interest margin on a fully taxable equivalent basis (NIM) (FTE) (non-GAAP) expanded 29 basis points to 4.33% compared to 4.04% in the prior quarter. The increase in NIM (FTE) (non-GAAP) was due to higher yields on loans only partially offset by a higher cost of interest-bearing liabilities.

Asset Quality

Total nonperforming assets decreased $6.7 million, or 23.2%, to $22.1 million at December 31, 2022 compared to $28.8 million at September 30, 2022. Nonperforming assets to total loans plus OREO, decreased 10 basis points to 0.31% at December 31, 2022 compared to 0.41% at September 30, 2022. Net loan charge-offs were $0.9 million for the fourth quarter of 2022 compared to $0.7 million in the third quarter of 2022.

The allowance for credit losses was 1.41% of total portfolio loans as of December 31, 2022 compared to 1.40% at September 30, 2022.

Noninterest Income and Expense

Noninterest income increased $0.8 million to $15.6 million in the fourth quarter of 2022 compared to $14.8 million in the third quarter of 2022. The increase in noninterest income was primarily due to higher other income of $1.7 million related to a net gain on the sale of OREO of $2.0 million. Noninterest expense increased $1.7 million to $51.3 million in the fourth quarter of 2022 compared to $49.6 million in the third quarter of 2022. The increase was

mainly due to an increase in salaries and employee benefits of $1.3 million compared to the prior quarter primarily due to higher incentives. The efficiency ratio (non-GAAP) improved to 48.73% compared to 50.19% for the third quarter of 2022.

Financial Condition

Total assets increased $0.2 billion to $9.1 billion at December 31, 2022 compared to $8.9 billion at September 30, 2022. Total portfolio loans increased $87.1 million, or 4.9% annualized, compared to September 30, 2022. Consumer loans increased $80.2 million, or 17.1% annualized, which primarily consisted of residential mortgage growth of $72.6 million, or 27.6% annualized. Total deposits decreased $190.6 million with decreases in all categories due to the competitive market driven by rising interest rates. 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 2022 Results (twelve months ended December 31, 2022)

Full year net income increased nearly 23% and was a record $135.5 million, or $3.46 per diluted share, for the year ended December 31, 2022 compared to net income of $110.3 million, or $2.81 per diluted share, for 2021.

Net interest income increased $39.7 million, or 14.4% compared to 2021 primarily due to the impact of rising interest rates. The yield on total average loans increased 66 basis points to 4.50% compared to 3.84% in 2021. Total interest-bearing deposit costs increased 20 basis points to 0.40% compared to 0.20% in 2021. Net interest margin (FTE) (non-GAAP) expanded 54 basis points to 3.76% compared to 3.22% for 2021. The increase in NIM (FTE) (non-GAAP) was due to higher yields on loans only partially offset by a higher cost of interest-bearing liabilities.

Noninterest income decreased $6.4 million compared to the prior year. Mortgage banking income decreased $7.5 million due to a decline in loan sale activity caused by rising interest rates and a shift to holding originated mortgage loans. Other income decreased $1.8 million compared to the prior year primarily related to the decline in the fair value of the assets in a nonqualified benefit plan and other market value adjustments partially offset by a net gain on the sale of OREO. Debit and credit card fees increased $1.1 million and service charges on deposit accounts increased $1.8 million due to increased customer activity. Noninterest expense increased $7.8 million compared to 2021. Salaries and employee benefits increased $3.0 million primarily due to higher incentives. Professional services and legal increased $2.0 million related to various consulting engagements during 2022. The efficiency ratio (non-GAAP) for 2022 was 52.34% compared to 55.06% for 2021.

Asset quality improved significantly during 2022. Nonperforming assets decreased $57.5 million, or 72.2%, to $22.1 million resulting in a nonperforming assets to total loans plus other real estate owned, or OREO, ratio of 0.31% compared to 1.13% at December 31, 2021. The provision for credit losses decreased $7.8 million to $8.4 million for 2022 compared to $16.2 million for 2021 primarily due to lower net charge-offs. Net loan charge-offs were $2.6 million for 2022 compared to $34.5 million for 2021. The allowance for credit losses was 1.41% of total portfolio loans as of December 31, 2022 and December 31, 2021.

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; 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; 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; 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
