Net Interest Income

Net interest income was $90.4 million in the second quarter of 2026 compared to $88.4 million in the first quarter of 2026. NIM (FTE) (non-GAAP) increased 7 basis points to 3.99% compared to 3.92% in the prior quarter. The yield on average interest-earning assets increased 4 basis points to 5.64% compared to 5.60% in the first quarter of 2026 primarily due to a higher yield on loans. Total interest-bearing liability costs decreased 4 basis points to 2.50% compared to 2.54% in the first quarter of 2026 mainly due to a better funding mix. Average brokered deposits decreased $146.2 million while average interest-bearing customer deposits increased $119.8 million compared to the first quarter of 2026.

Asset Quality

The allowance for credit losses, or ACL, was unchanged at $93.3 million, or 1.16% of total portfolio loans, at June 30, 2026 compared to $93.3 million, or 1.17%, at March 31, 2026. The provision for credit losses was $1.1 million for the second quarter of 2026 compared to $1.3 million in the first quarter of 2026. Net loan charge-offs were $1.0 million, or 0.05% of average loans, compared to $1.7 million, or 0.09% of average loans, in the first quarter of 2026. NPAs decreased $9.7 million to $40.2 million, or 0.50% of total loans plus OREO, compared to $49.9 million, or 0.63%, at March 31, 2026.

Noninterest Income and Expense

Noninterest income increased $1.3 million to $14.9 million in the second quarter of 2026 compared to $13.6 million in the first quarter of 2026. Higher noninterest income related to a $0.4 million increase in debit and credit card fees due to the first quarter of 2026 being seasonally lower and a $0.3 million increase in other income primarily related to partnership income and unrealized gains on equity securities. Additionally, during the second quarter of 2026 there was a $0.2 million net gain on the sale of securities resulting from a $1.9 million gain related to Visa Class B-2 common stock conversion, which was mostly offset by a $1.7 million loss related to the repositioning of securities into longer duration, higher yielding securities.

Noninterest expense increased $2.0 million to $58.7 million in the second quarter of 2026 compared to $56.7 million in the first quarter of 2026. Salaries and employee benefits increased $1.3 million primarily related to annual merit increases and higher medical costs. Other noninterest expense increased $1.0 million primarily due to normal fluctuations across several expense categories and timing-related items.

Financial Condition

Total assets were $9.9 billion at both June 30, 2026 and March 31, 2026. Cash and due from banks decreased $121.2 million related to an increase in loans compared to March 31, 2026. Total portfolio loans increased $99.0 million compared to March 31, 2026 with an increase in the commercial loan portfolio of $104.2 million and a decrease in the consumer loan portfolio of $5.2 million. The increase in the commercial loan portfolio was due to an increase in commercial and industrial of $79.0 million and an increase in commercial construction of $71.4 million, offset by a decline in commercial real estate of $46.2 million compared to March 31, 2026. Total deposits decreased $99.1 million due to lower brokered deposits of $100.4 million compared to March 31, 2026. Customer deposits were stable in the second quarter, following solid growth in the first quarter of 2026 with year-to-date growth of $307.7 million, or 8.0% annualized. Money market decreased $80.8 million, noninterest bearing deposits decreased $16.9 million, interest-bearing demand decreased $14.8 million and savings decreased $1.2 million, offset by an increase in certificates of deposit of $14.7 million, compared to March 31, 2026. The decrease in money market of $80.8 million is net of a decline in brokered money market deposits of $100.4 million offset by an increase in customer money market deposits of $19.6

million compared to March 31, 2026. Total borrowings increased $125.0 million to $275.3 million compared to $150.3 million at March 31, 2026 due to a decrease in brokered deposits and share repurchases.

During the second quarter of 2026, 1,074,924 shares were repurchased at an average price of $44.24 per share for $47.6 million. Total share repurchases over the past three quarters were 3,169,294 shares, representing 8.3% of outstanding shares, at an average price of $42.09 per share totaling $133.4 million.

S&T continues to maintain a strong regulatory capital position with all capital ratios above the well-capitalized thresholds of federal bank regulatory agencies.

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, 2025, including Part I, Item 1A-"Risk Factors" and any of our subsequent filings with the SEC.

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 on average tangible shareholders' equity, PPNR to average assets, efficiency ratio on an FTE basis, 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.

Tangible book value (non-GAAP)	$29.18		$29.11		$27.90
Tangible book value is a preferred industry metric used to measure our company's value and commonly used by investors and analysts.

(2) Return on Average Tangible Shareholders' Equity (non-GAAP)

Return on average tangible shareholders' equity (non-GAAP)	14.15	%	13.22	%	12.12	%
Return on average tangible shareholders' equity is a preferred industry profitability metric used by management, as well as investors and analysts, to measure financial performance.

(3) Pre-provision Net Revenue / Average Assets (non-GAAP)
Income before taxes	$45,464		$44,044		$39,984

Pre-provision Net Revenue / Average Assets (non-GAAP)	1.89	%	1.87	%	1.73	%
Pre-provision net revenue to average assets is income before taxes adjusted to exclude provision for credit losses, losses (gains) on sale of securities and gain on Visa exchange. We believe this to be a preferred industry measurement to help management, as well as investors and analysts, evaluate our ability to fund credit losses or build capital.

(4) Efficiency Ratio (FTE) (non-GAAP)
Noninterest expense	$58,664		$56,707		$58,114

Net interest income (FTE) (non-GAAP) plus noninterest income	$105,655		$102,668		$100,662
Efficiency ratio (FTE) (non-GAAP)	55.52	%	55.23	%	57.73	%
The efficiency ratio is noninterest expense divided by noninterest income plus net interest income, on an FTE basis (non-GAAP), adjusted to exclude losses (gains) on sale of securities and gain on Visa exchange. We believe the FTE basis ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice.

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.

Second Quarter 2026 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; cybersecurity concerns; rapid technological developments and changes, including the use of artificial intelligence and digital assets; operational risks or risk management failures by us or critical third parties, including fraud risk; our ability to manage our brand 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; 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; 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 other employees; general economic or business conditions, including the strength of regional economic conditions in our market area; ESG 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 and geopolitical tensions and conflicts between nations. 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, 2025, 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 on average tangible shareholders’ equity, PPNR to average assets, efficiency ratio on an FTE basis, 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. 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 on Form 10-Q and in Exhibit 99.1 of Form 8-K for S&T Bancorp, Inc. and subsidiaries. 2
