**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**NOTE 1. BASIS OF PRESENTATION**

**Principles of Consolidation**

The interim Condensed Consolidated Financial Statements include the accounts of S&T Bancorp, Inc., or S&T, and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. Investments of 20 percent to 50 percent of the outstanding common stock of investees are accounted for using the equity method of accounting.

**Basis of Presentation**

The accompanying unaudited interim Condensed Consolidated Financial Statements of S&T have been prepared in accordance with generally accepted accounting principles, or GAAP, in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2024, or 2024 Form 10-K, filed with the Securities and Exchange Commission, or SEC. In the opinion of management, the accompanying interim financial information reflects all adjustments, consisting of normal recurring adjustments, necessary to present fairly our financial position and the results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year or any future period.

**Reclassification**

Amounts in prior period financial statements and footnotes are reclassified whenever necessary to conform to the current period presentation. Reclassifications had no effect on our condensed consolidated financial statements.

**Use of Estimates**

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

**Segments**

We have one operating segment, Community Banking, based upon our current reporting structure at the consolidated level. The chief operating decision maker, or CODM, uses consolidated net income when allocating resources and making operating decisions. The accounting policies used to measure the profit and loss of the Community Banking segment are the same as those described in the summary of significant accounting policies. The CODM does not review segment revenue or expense information at a lower level than what is included in our Consolidated Statements of Net Income. Expenses included within other expenses in the Condensed Consolidated Statements of Comprehensive Income include loan related expenses, travel and entertainment, telephone and contributions.

**Recently Adopted Accounting Standards Updates, or ASU, or Updated**

***Income Taxes (Topic 740) Improvements to Income Tax Disclosures***

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures to enhance the transparency and decision usefulness of the disclosures. The amendments in this update address investor requests for more transparency about income tax information through improvements to disclosures primarily related to the rate reconciliation and income taxes paid information. The amendments in this update are effective for fiscal years beginning after December 15, 2024. We adopted ASU 2023-09, as of January 1, 2025 with no impact to the consolidated financial statements. We will provide the required updated disclosures in our Form 10-K for the year ended December 31, 2025.

**Recently Issued Accounting Standards Not Yet Adopted**

***Income Statement (Subtopic 220-40)—Reporting Comprehensive Income—Expense Disaggregation Disclosures***

In November 2024, the FASB issued ASU 2024-03, Income Statement (Subtopic 220-40)—Reporting Comprehensive Income—Expense Disaggregation Disclosures to improve the disclosures about a public business entity's expenses and address requests from investors for more detailed information about the types of expenses in commonly presented expense captions. The amendments in this update are effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. This ASU will not impact our consolidated financial statements and we are currently evaluating the impact of the new disclosure requirements.

**NOTE 2. EARNINGS PER SHARE**

Diluted earnings per share is calculated using both the two-class and the treasury stock methods with the more dilutive method used to determine diluted earnings per share. The treasury stock method was used to determine earnings per share for the three and six months ended June 30, 2025 and June 30, 2024.

The following table reconciles the numerators and denominators of basic and diluted EPS calculations for the periods presented:

**NOTE 3. FAIR VALUE MEASUREMENTS**

We use fair value measurements when recording and disclosing certain financial assets and liabilities. Debt securities, equity securities, securities held in a deferred compensation plan and derivative financial instruments are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record other financial instruments at fair value on a nonrecurring basis, such as loans held for sale, loans individually evaluated, other real estate owned, or OREO, and other repossessed assets, mortgage servicing rights, or MSRs, and certain other assets.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction. In determining fair value, we use various valuation approaches, including market, income and cost approaches. The fair value standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability, which are developed based on market data that we have obtained from independent sources. Unobservable inputs reflect our estimates of assumptions that market participants would use in pricing an asset or liability, which are developed based on the best information available in the circumstances.

The fair value hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows.

Level 1: valuation is based upon unadjusted quoted market prices for identical instruments traded in active markets.

Level 2: valuation is based upon quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by market data.

Level 3: valuation is derived from other valuation methodologies, including discounted cash flow models and similar techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in determining fair value.

A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

There have been no changes in our valuation methodologies during the three and six months ended June 30, 2025. Refer to Note 1. Summary of Significant Accounting Policies of the Notes to Consolidated Financial Statements in our 2024 Form 10-K for more information on the valuation methodologies that we use for financial instruments recorded at fair value on a recurring or nonrecurring basis.

**Assets Recorded at Fair Value on a Nonrecurring Basis**

We may be required to measure certain assets and liabilities at fair value on a nonrecurring basis. Nonrecurring assets are recorded at the lower of cost or fair value in our consolidated financial statements. There were no liabilities measured at fair value on a nonrecurring basis at both June 30, 2025 and December 31, 2024. There were no assets measured at fair value on a nonrecurring basis as of June 30, 2025. As of December 31, 2024, individually evaluated loans of $6.8 million were measured at fair value and classified as Level 3 on a nonrecurring basis.

Significant unobservable inputs used in the fair value measurements of Level 3 assets on a nonrecurring basis were as follows at December 31, 2024:

We evaluate securities with unrealized losses quarterly to determine if the decline in fair value has resulted from credit impairment or other factors. We do not believe any individual unrealized loss as of June 30, 2025 represents a credit impairment. The unrealized losses on debt securities were attributable to changes in interest rates and not related to the credit quality of the issuers. All debt securities were determined to be investment grade and paying principal and interest according to the contractual terms of the security. At June 30, 2025, we do not intend to sell, and it is more likely than not that we will not be required to sell, the securities in an unrealized loss position before recovery of their amortized cost.

A payment default is defined as a loan having a payment past due 90 days or more. There was one payment default in the amount of $0.1 million during the three months ended June 30, 2025 and two payment defaults in the amount of $3.9 million in the six months ended June 30, 2025 compared to none in the same periods in 2024. Additionally, we had 11 commitments to lend an additional $0.1 million to borrowers experiencing financial difficulty that had a modification during the twelve months ended June 30, 2025 and three commitments to lend an additional $1.2 million to borrowers experiencing financial difficulty that had a modification during the same period in 2024.

The effect of modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses, or ACL, because of the measurement methodologies used to estimate the ACL, therefore, a change to the ACL is generally not recorded upon modification. If principal forgiveness is provided, that portion of the loan will be charged-off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the ACL. An assessment of whether the borrower is experiencing financial difficulty is made on the date of a modification.

**Allowance for Credit Losses**

We maintain an ACL, at a level determined to be adequate to absorb estimated expected credit losses within the loan portfolio over the contractual life of an instrument that considers our historical loss experience, current conditions and forecasts of future economic conditions as of the balance sheet date. We develop and document a systematic ACL methodology based on the following portfolio segments: 1) CRE, 2) C&I, 3) Commercial Construction, 4) Business Banking, 5) Consumer Real Estate and 6) Other Consumer.

The following are key risks within each portfolio segment:

***CRE***—Loans secured by commercial purpose real estate, including both owner-occupied properties and investment properties for various purposes such as hotels, retail, multifamily and health care. Operations of the individual projects and global cash flows of the debtors are the primary sources of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the collateral type and the business prospects of the lessee, if the project is not owner-occupied.

***C&I***—Loans made to operating companies or manufacturers for the purpose of production, operating capacity, accounts receivable, inventory or equipment financing. Cash flow from the operations of the company is the primary source of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the industry of the company. Collateral for these types of loans often does not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt.

***Commercial Construction***—Loans made to finance construction of buildings or other structures, as well as to finance the acquisition and development of raw land for various purposes. While these loans are generally confined to the construction

period, if there are problems, the project may not be completed, and as such, may not provide sufficient cash flow on its own to service the debt or have sufficient value in a liquidation to cover the outstanding principal. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the type of project and the experience and resources of the developer.

***Business Banking***—Commercial purpose loans made to small businesses that are standard, non-complex products evaluated through a streamlined credit approval process that has been designed to maximize efficiency while maintaining high credit quality standards that meet small business market customers' needs. The business banking portfolio is monitored by utilizing a standard and closely managed process focusing on behavioral and performance criteria. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the collateral type and business.

***Consumer Real Estate***—Loans secured by first and second liens such as 1-4 family residential mortgages, home equity loans and home equity lines of credit. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The state of the local housing market can also have a significant impact on this segment because low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.

***Other Consumer***—Loans made to individuals that may be secured by assets other than 1-4 family residences, as well as unsecured loans. This segment includes auto loans, unsecured loans and lines of credit. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.

Management monitors various credit quality indicators for the commercial, business banking and consumer loan portfolios, including changes in risk ratings, nonperforming status and delinquency on a monthly basis.

We monitor the commercial and business banking loan portfolio through an internal risk rating system. Loan risk ratings are assigned based upon the creditworthiness of the borrower and are reviewed on an ongoing basis according to our internal policies. Loans within the pass rating generally have a lower risk of loss than loans risk rated as special mention or substandard.

Our risk ratings are consistent with regulatory guidance and are as follows:

***Pass***—The loan is currently performing and is of high quality.

***Special Mention***—A special mention loan has potential weaknesses that warrant management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects or in the strength of our credit position at some future date.

***Substandard***—A substandard loan is not adequately protected by the net worth and/or paying capacity of the borrower or by the collateral pledged, if any. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. These loans are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected.

***Doubtful***—Loans classified doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable.

Amounts reported in OCI related to derivatives that are designated as hedging instruments are reclassified to interest income as interest payments are received on variable rate assets. During the next twelve months, we estimate that an additional $4.1 million will be reclassified as a decrease to interest income. Our current interest rate swap agreements have three to five year terms with maturity dates extending into 2027.

**NOTE 8. COMMITMENTS AND CONTINGENCIES**

**Commitments**

In the normal course of business, we offer off-balance sheet credit arrangements to enable our customers to meet their financing objectives. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated financial statements. Our exposure to credit loss, in the event the customer does not satisfy the terms of the agreement, equals the contractual amount of the obligation less the value of any collateral. We apply the same credit policies in making commitments and standby letters of credit that are used for the underwriting of loans to customers. Commitments generally have fixed expiration dates, annual renewals or other termination clauses and may require payment of a fee. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.

The following table sets forth our commitments and letters of credit as of the dates presented:

---

| | | |
|:---|:---|:---|
| *(dollars in thousands)* | **June 30, 2025** | **December 31, 2024** |
| Commitments to extend credit | $2527223 | $2382847 |
| Standby letters of credit | 66825 | 69558 |
| **Total** | $**2594048** | $**2452405** |

---

**Litigation**

In the normal course of business, we are subject to various legal and administrative proceedings and claims. While any type of litigation contains a level of uncertainty, we believe that the outcome of such proceedings or claims pending will not have a material adverse effect on our consolidated financial position or results of operations.

**Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

Management's Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, represents an overview of our consolidated results of operations and financial condition and highlights material changes in our financial condition and results of operations for the three and six months ended June 30, 2025 and 2024. Our MD&A should be read in conjunction with our Consolidated Financial Statements and Notes. The results of operations reported in the accompanying Consolidated Financial Statements are not necessarily indicative of results to be expected in future periods.

 **Important Note Regarding Forward-Looking Statements**

This Quarterly Report on Form 10-Q 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; 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, 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 elsewhere in this report, and under Part I, Item 1A - "Risk Factors" of our 2024 Form 10-K, 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.

**Critical Accounting Policies and Estimates** 

We view critical accounting policies to be those which are highly dependent on subjective or complex estimates, assumptions and judgments and where changes in those estimates and assumptions could have a significant impact on the Consolidated Financial Statements. Further, we view critical accounting estimates as those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial condition or results of operations. Our critical accounting policies and estimates as of June 30, 2025 remained unchanged from the disclosures presented in our 2024 Form 10-K under Part II, Item 7 - "Management's Discussion and Analysis of Financial Condition and Results of Operations."

**Explanation of Use of Non-GAAP Financial Measures**

In addition to traditional financial measures presented in accordance with GAAP, our management uses, and this report contains or references, certain non-GAAP financial measures discussed below. We believe these non-GAAP financial measures provide information useful to investors in understanding our underlying business, operational performance 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 interest income on interest-earning assets, net interest income and net interest margin are presented on an FTE basis (non-GAAP). 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.

The following table reconciles interest and dividend income and net interest income per the Condensed Consolidated Statements of Comprehensive Income to interest income, net interest income and net interest margin on an FTE basis (non-GAAP) for the periods presented:

We recognized net income of $31.9 million, or $0.83 per diluted share, for the three months ended June 30, 2025 compared to net income of $34.4 million, or $0.89 per diluted share, for the same period in 2024 and net income of $65.3 million, or $1.69 per diluted share, for the six months ended June 30, 2025 compared to net income of $65.6 million, or $1.70 per diluted share, for the same period in 2024.

Net interest income increased $3.0 million, or 3.56 percent, and $2.8 million, or 1.69 percent, for the three and six months ended June 30, 2025 compared to the same periods in 2024. Net interest margin, or NIM, on an FTE basis (non-GAAP) increased 3 basis points to 3.88% for the three months ended June 30, 2025 compared to 3.85% in the same period in 2024 and remained unchanged at 3.84% for the six months ended June 30, 2025 and June 30, 2024. These improvements in both net interest income on an FTE basis (non-GAAP) and NIM on an FTE basis (non-GAAP) were primarily due to the impact of lower interest rates on interest bearing liabilities and an improvement on our overall funding mix. Strong customer deposit growth in 2024 and 2025 has reduced our levels of wholesale funding.

The provision for credit losses increased $1.6 million to $2.0 million for the three months ended June 30, 2025 compared to $0.4 million for the same period in 2024. The increase was primarily due to a higher provision for unfunded loan commitments and an increase in loan charge-offs which was partially offset by a lower level of allowance for credit losses, or ACL, due to improved asset quality. The provision for credit losses decreased $4.1 million to a negative $1.1 million for the six months ended June 30, 2025 compared to $3.0 million for the same period in 2024. The decrease was due to a lower level of ACL related to improved asset quality, including a $4.2 million reduction in specific reserves for individually evaluated loans during the three months ended March 31, 2025, and a decrease in loan charge-offs.

Noninterest income increased $0.2 million for the three months ended June 30, 2025 and decreased $2.2 million for the six months ended June 30, 2025 compared to the same periods in 2024. The increase of $0.2 million related to no security losses for the three months ended June 30, 2025 compared to $3.2 million of losses in the same period in the prior year offset by a $2.9 million decline in other noninterest income primarily related to a fair value adjustment of $3.2 million from the Visa exchange offer for Visa Class B-1 common stock in the three months ended June 30, 2024. The $2.2 million decrease in noninterest income for the six months ended June 30, 2025 was primarily related to the fair value adjustment of $3.2 million for the Visa exchange offer offset by lower losses on securities in the six months ended June 30, 2025.

Noninterest expense increased $4.5 million, or 8.41 percent, and $5.1 million, or 4.70 percent, for the three and six months ended June 30, 2025 compared to the same periods in 2024. The most significant change in noninterest expense related to salaries and employee benefits which increased $2.5 million and $2.9 million for the three and six months ended June 30, 2025 compared to the same periods in 2024 due to annual merit increases, higher incentives and increased medical costs.

Our effective tax rate was 20.2 percent and 20.1 percent for the three and six months ended June 30, 2025 compared to 19.8 percent and 20.0 percent for the three and six months ended June 30, 2024. The increase in the effective tax rate for the three and six months ended June 30, 2025 was primarily due to a decrease in tax-exempt interest income partially offset by an increase in low-income housing tax credits compared to the same period in 2024.

**Net Interest Income**

Our principal source of revenue is net interest income. Net interest income represents the difference between the interest and fees earned on interest-earning assets and the interest paid on interest-bearing liabilities. Net interest income is affected by changes in the average balance of interest-earning assets and interest-bearing liabilities and changes in interest rates and spreads. The level and mix of interest-earning assets and interest-bearing liabilities is managed by our Asset and Liability Committee, or ALCO, in order to mitigate interest rate and liquidity risks of the balance sheet. A variety of ALCO strategies were implemented, within prescribed ALCO risk parameters, to produce what we believe is an acceptable level of net interest income.

**Average Balance Sheet and Net Interest Income Analysis (FTE) (non-GAAP)**

Net interest income on an FTE basis (non-GAAP) increased $2.9 million, or 3.4 percent, and $2.7 million, or 1.6 percent, for the three and six months ended June 30, 2025 compared to the same periods in 2024. NIM on an FTE basis (non-GAAP) increased 3 basis points for the three months ended June 30, 2025 and remained unchanged for the six months ended June 30, 2025 compared to the same periods in 2024. These improvements in both net interest income and NIM, on an FTE basis (non-GAAP) were primarily due to the impact of lower interest rates on interest bearing liabilities and an improvement in our overall funding mix. Strong customer deposit growth in 2024 and 2025 has reduced our levels of borrowings and brokered deposits.

**Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

Interest income on an FTE basis (non-GAAP) remained relatively unchanged for the three months ended June 30, 2025 and decreased $2.9 million for the six months ended June 30, 2025 compared to the same periods in 2024. The decrease in interest income on an FTE basis (non-GAAP) for the six months ended June 30, 2025 was primarily due to lower interest rates. The average yield on loan balances decreased 26 basis points for both the three and six months ended June 30, 2025 compared to the same periods in 2024. Average loan balances increased $185.0 million and $142.3 million for the three and six months ended June 30, 2025 compared to the same periods in 2024. Partially offsetting the lower interest income on loans was higher interest income on securities primarily due to the repositioning of $193.6 million of securities during 2024 and 2025. The average yield on securities increased 86 and 82 basis points for the three and six months ended June 30, 2025 compared to the same periods in 2024. Overall, the FTE rate (non-GAAP) on interest-earning assets decreased 15 and 16 basis points for the three and six months ended June 30, 2025 compared to the same periods in 2024.

Interest expense decreased $2.8 million and $5.6 million for the three and six months ended June 30, 2025 compared to the same periods in 2024. The decrease in interest expense was primarily due to lower levels of borrowings and decreased interest rates. Average interest-bearing deposits increased $253.8 million and $269.9 million for the three and six months ended June 30, 2025 compared to the same periods in 2024 primarily due to increases in certificates of deposit and money market balances. Average borrowings decreased $114.4 million and $196.6 million for the three and six months ended June 30, 2025 compared to the same periods in 2024 primarily due to increased customer deposits. Overall, the cost of interest-bearing liabilities decreased 26 and 21 basis points for the three and six months ended June 30, 2025 compared to the same periods in 2024.

The following table sets forth for the periods presented a summary of the changes in interest earned and interest paid resulting from changes in volume and changes in rates:

**Provision for Credit Losses**

The provision for credit losses includes a provision for losses on loans and on unfunded commitments. The provision for credit losses fluctuates based on changes in loan balances, loan risk ratings, net loan charge-offs and recoveries, the macro environment and our CECL forecast.

The provision for credit losses increased $1.6 million to $2.0 million for the three months ended June 30, 2025 compared to $0.4 million for the same period in 2024. The increase was primarily due to a higher provision for unfunded loan commitments and an increase in loan charge-offs which was partially offset by a lower level of ACL due to improved asset quality. The provision for credit losses decreased $4.1 million to a negative $1.1 million for the six months ended June 30, 2025 compared to $3.0 million for the same period in 2024. The decrease was due to a lower level of ACL related to improved asset quality, including a $4.2 million reduction in specific reserves for individually evaluated loans during the three months ended March 31, 2025, and a decrease in loan charge-offs.

Net loan charge-offs were $1.2 million and $1.1 million for the three and six months ended June 30, 2025 compared to net loan recoveries of $0.4 million and net loan charge-offs of $6.2 million for the same periods in 2024.

Noninterest income increased $0.2 million for the three months ended June 30, 2025 and decreased $2.2 million for the six months ended June 30, 2025 compared to the same periods in 2024. The increase of $0.2 million related to no security losses recognized for the three months ended June 30, 2025 compared to $3.2 million of losses recognized in the same period in the prior year offset by a $2.9 million decline in other noninterest income primarily related to a fair value adjustment of $3.2 million from the Visa exchange offer for Visa Class B-1 common stock in the three months ended June 30, 2024. The decrease of $2.2 million in noninterest income for the six months ended June 30, 2025 was primarily related to the fair value adjustment of $3.2 million for the Visa exchange offer in 2024 offset by lower losses on securities in the six months ended June 30, 2025.

Salaries and employee benefits increased $2.5 million and $2.9 million for the three and six months ended June 30, 2025 primarily due to annual merit increases, higher incentives and increased medical costs. Data processing and information technology increased $0.6 million for both the three and six months ended June 30, 2025 compared to the same periods in 2024 due to additional services provided through our third party vendor. Occupancy increased $0.4 million and $0.8 million for the three and six months ended June 30, 2025 due to increased maintenance and utility costs. Other taxes increased $0.7 million and $0.3 million for the three and six months ended June 30, 2025 due to the timing of education and Neighborhood Assistance Program, or NAP, contribution credits and higher shares tax compared to the same periods in 2024. Professional services and legal expense increased $0.3 million for the three months ended June 30, 2025 due to additional consulting engagements and increased legal expenses. Other noninterest expense increased $0.9 million for the six months ended June 30, 2025 compared to the same periods in 2024 primarily related to higher loan collection, recruitment and charitable contribution expenses.

**Provision for Income Taxes**

The provision for income taxes decreased $0.4 million to $8.1 million for the three months ended June 30, 2025 compared to $8.5 million for the same period in 2024 and remained unchanged at $16.4 million for the six months ended June 30, 2025 and the same period in 2024. Our effective tax rate was 20.2 percent for the three months ended June 30, 2025 and 20.1 percent for the six months ended June 30, 2025 compared to 19.8 percent and 20.0 percent for the same periods in 2024. The increase in our effective tax rate for the three and six month periods ended June 30, 2025 was primarily due to a decrease in tax-exempt interest income partially offset by an increase in low-income housing tax credits compared to the same periods in 2024.

On July 4, 2025, "An Act to Provide for Reconciliation Pursuant to Title II of H. Con. Res. 14" was signed into law. The Act extends many of the key provisions of the 2017 Tax Cuts and Jobs Act, or TCJA, which were previously set to expire at the end of this year, and introduces several new tax measures.We are currently evaluating income tax implications of the Act. We do not expect the Act to have a material impact on our consolidated financial statements.

**Financial Condition as of June 30, 2025**

Total assets increased $152.1 million to $9.8 billion at June 30, 2025 compared to $9.7 billion at December 31, 2024. Total portfolio loans increased $191.5 million to $7.9 billion at June 30, 2025 compared to December 31, 2024. The commercial loan portfolio increased $148.8 million and the consumer loan portfolio increased $42.7 million compared to December 31, 2024.

Securities increased $33.6 million to $1.0 billion at June 30, 2025 compared to December 31, 2024 mainly due to a decrease in unrealized losses. The securities portfolio was in a net unrealized loss position of $46.1 million at June 30, 2025 compared to a net unrealized loss position of $71.7 million at December 31, 2024. The improvement in the net unrealized loss position of the securities portfolio of $25.6 million was primarily due to a decline in interest rates from December 31, 2024.

Customer deposit growth during the six months ended June 30, 2025 resulted in a reduction in brokered deposits. Total deposits increased $137.8 million to $7.9 billion at June 30, 2025 compared to $7.8 billion at December 31, 2024. Customer deposits increased $162.6 million to $7.7 billion at June 30, 2025 compared to $7.6 billion at December 31, 2024. Brokered deposits decreased $24.8 million to $200.5 million at June 30, 2025 compared to $225.3 million at December 31, 2024. The increase in customer deposits is the result of our continued focus on growing our deposit franchise.

Total borrowings remained unchanged at $250.3 million for June 30, 2025 and December 31, 2024.

Total shareholders' equity increased by $65.2 million to $1.4 billion at June 30, 2025 compared to December 31, 2024. The increase was primarily due to net income of $65.3 million and other comprehensive income of $24.6 million offset by dividends of $26.2 million.

**Item 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

We invest in various securities in order to maintain a source of liquidity, to satisfy various pledging requirements, to increase net interest income and as a tool of ALCO to reposition the balance sheet for interest rate risk purposes. Securities are subject to market risks that could negatively affect the level of liquidity available to us.

The securities portfolio increased $33.6 million to $1.0 billion at June 30, 2025 compared to December 31, 2024. The increase in the debt securities portfolio was primarily related to an improvement in unrealized losses of $25.6 million at June 30, 2025 compared to December 31, 2024 as a result of lower interest rates. Additionally, we had $2.3 million of realized losses due to the repositioning of $49.3 million of our securities portfolio into longer duration, higher-yielding securities during the three months ended March 31, 2025.

Our debt securities portfolio was in a net unrealized loss position of $46.1 million at June 30, 2025 compared to a net unrealized loss position of $71.7 million at December 31, 2024. At June 30, 2025, our debt securities portfolio had gross unrealized losses of $51.7 million offset by $5.6 million of gross unrealized gains compared to gross unrealized losses of $72.7 million offset by gross unrealized gains of $1.0 million at December 31, 2024.

The loan portfolio represents the most significant source of interest income for us. The risk that borrowers will be unable to pay such obligations is inherent in the loan portfolio. Other conditions, such as downturns in the borrower's industry or the overall economic climate, can significantly impact the borrower's ability to pay.

Total portfolio loans were $7.9 billion at June 30, 2025 compared to $7.7 billion at December 31, 2024. As of June 30, 2025, 22 percent of our total loans were adjustable rate, 38 percent were floating rate and 40 percent were fixed rate compared to 24 percent adjustable rate loans, 37 percent floating rate loans and 39 percent fixed rate loans at December 31, 2024.

Commercial loans, including CRE, C&I and commercial construction comprised 68.4 percent of total portfolio loans at June 30, 2025 and 68.2 percent at December 31, 2024. The commercial loan portfolio increased $148.8 million at June 30, 2025 compared to December 31, 2024 due to increases of $132.3 million in CRE and $44.9 million in commercial construction offset by a decrease of $28.4 million in C&I.

Consumer loans represent 31.6 percent of our total portfolio loans at June 30, 2025 and 31.8 percent at December 31, 2024. The consumer loan portfolio increased $42.7 million at June 30, 2025 compared to December 31, 2024 primarily due to growth in our consumer real estate portfolio of $47.3 million.

**Allowance for Credit Losses**

We maintain an ACL at a level determined to be adequate to absorb estimated expected credit losses within the loan portfolio over the contractual life of an instrument that considers our historical loss experience, current conditions and forecasts of future economic conditions as of the balance sheet date. We develop and document a systematic ACL methodology based on the following portfolio segments: 1) CRE, 2) C&I, 3) Commercial Construction, 4) Business Banking, 5) Consumer Real Estate and 6) Other Consumer. Refer to Part 1. Financial Information, Note 5. Loans and Allowance for Credit Losses for details on our portfolio segments.

<sup>(1)</sup> *Year-to-date net charge-offs annualized*

The ACL decreased $2.9 million to $98.6 million, or 1.24 percent of total portfolio loans, at June 30, 2025 compared to $101.5 million, or 1.31 percent of total portfolio loans, at December 31, 2024. The decrease of $2.9 million in the ACL was primarily due to a reduction in specific reserves for loans individually evaluated related to the partial pay-off in 2025 of a $10.7 million C&I relationship that went nonperforming during the three months ended December 31, 2024. The decrease in the ACL was partially offset by a $0.9 million increase in our quantitative reserve primarily due to loan growth.

Substandard and special mention loans remain relatively stable at June 30, 2025 following significant reductions during 2024. Substandard loans were $113.9 million at June 30, 2025 compared to $109.8 million at December 31, 2024. Special mention loans were $99.4 million at June 30, 2025 compared to $98.9 million at December 31, 2024.

Nonperforming assets, or NPAs, consist of nonaccrual loans and OREO. The following represents NPAs as of the dates presented:

Our policy is to place loans in all categories in nonaccrual status when collection of interest or principal is doubtful, or generally when interest or principal payments are 90 days or more past the contractual due date. Nonaccrual loans decreased $6.6 million to $21.3 million at June 30, 2025 compared to $27.9 million at December 31, 2024. The decrease in nonaccrual loans was primarily due to the partial pay-off of the $10.7 million C&I relationship mentioned above.

 **Liquidity and Capital Resources**

Liquidity is defined as a financial institution's ability to meet its cash and collateral obligations at a reasonable cost. Our primary future cash needs are centered on the ability to (i) satisfy the financial needs of depositors who may want to withdraw funds or of borrowers needing to access funds to meet their credit needs and (ii) to meet our future cash commitments under contractual obligations with third parties. In order to manage liquidity risk, our Board of Directors has delegated authority to ALCO for the formulation, implementation and oversight of liquidity risk management for S&T. ALCO's goal is to maintain adequate levels of liquidity at a reasonable cost to meet funding needs in both a normal operating environment and for potential liquidity stress events. ALCO monitors and manages liquidity through various ratios, reviewing cash flow projections, performing stress tests and having a detailed contingency funding plan. ALCO policy guidelines define graduated risk tolerance levels. If our liquidity position moves to a level that has been defined as high risk, specific actions are required, such as increased monitoring or the development of an action plan to reduce the risk position.

Our primary funding and liquidity source is a stable customer deposit base. We believe S&T has the ability to retain existing deposits and attract new deposits, mitigating any funding dependency on other more volatile funding sources. Refer to the "Financial Condition as of June 30, 2025 - Deposits" section of this MD&A, for additional discussion on deposits. Although deposits are the primary source of funds, we have identified various other funding sources that can be used as part of our normal funding program. Additional funding sources accessible to S&T include borrowing availability at the FHLB, federal funds lines with other financial institutions and the brokered deposit market. We also have borrowing availability at the Federal Reserve Discount Window through the Borrower-in-Custody Program.

We have contractual obligations representing required future payments on certificates of deposit, junior subordinated debt securities, short-term borrowings, long-term borrowings, operating and capital leases, funding commitments on tax credit equity investments and purchase obligations. See the "Liquidity and Capital Resources" section presented in our Form 2024 10-K under Part II, Item 7- "Management's Discussion and Analysis of Financial Condition and Results of Operations" for more information on these future cash outflows. There have been no material changes to the contractual obligations previously disclosed in our 2024 Form 10-K.

An important component of our ability to effectively respond to potential liquidity stress events is maintaining a cushion of highly liquid assets. Highly liquid assets are those that can be converted to cash quickly to meet financial obligations. ALCO policy guidelines define a ratio of highly liquid assets to total assets by graduated risk tolerance levels of minimal, moderate and high. At June 30, 2025, S&T Bank had $912.2 million in highly liquid assets, which consisted primarily of $113.5 million in interest-bearing deposits with banks and $798.7 million in unpledged securities. This resulted in a highly liquid assets to total assets ratio of 9.3 percent at June 30, 2025.

We continue to maintain a strong capital position with our capital ratios in excess of the well-capitalized regulatory guidelines. The following table summarizes capital amounts and ratios for S&T and S&T Bank as of the dates presented:

We have filed a shelf registration statement on Form S-3 under the Securities Act of 1933, as amended, with the SEC, which allows for the issuance of a variety of securities including debt and capital securities, preferred and common stock and warrants. We may use the proceeds from the sale of securities for general corporate purposes, which could include investments at the holding company level, investing in, or extending credit to subsidiaries, possible acquisitions and stock repurchases. We have not issued any securities pursuant to this shelf registration statement at June 30, 2025.

**Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

Market risk is defined as the degree to which changes in interest rates, foreign exchange rates, commodity prices or equity prices can adversely affect a financial institution's earnings or capital. For most financial institutions, including S&T, market risk primarily reflects exposures to changes in interest rates. Interest rate fluctuations affect earnings by changing net interest income and other interest-sensitive income and expense levels. Interest rate changes also affect capital by changing the net present value of a bank's future cash flows, and the cash flows themselves, as rates change. Accepting this risk is a normal part of banking and can be an important source of profitability and enhancing shareholder value. However, excessive interest rate risk can threaten a bank's earnings, capital, liquidity and solvency. Our sensitivity to changes in interest rate movements is continually monitored by ALCO. ALCO monitors and manages market risk through rate shock analyses, economic value of equity, or EVE, analyses and by performing stress tests and simulations to mitigate earnings and market value fluctuations due to changes in interest rates.

Rate shock analyses results are compared to a base case to provide an estimate of the impact that market rate changes may have on 12 and 24 months of pretax net interest income. The base case and rate shock analyses are performed on a static balance sheet. A static balance sheet is a no growth balance sheet in which all maturing and/or repricing cash flows are reinvested in the same product at the existing product spread. Rate shock analyses assume an immediate parallel shift in market interest rates and also include management assumptions regarding the impact of interest rate changes on non-maturity deposit products (noninterest-bearing demand, interest-bearing demand, money market and savings) and changes in the prepayment behavior of loans and securities with optionality. S&T policy guidelines limit the change in pretax net interest income over 12 and 24 month horizons using rate shocks in increments of +/- 100 basis points. Policy guidelines define the percentage change in pretax net interest income by graduated risk tolerance levels of minimal, moderate and high.

In order to monitor interest rate risk beyond the 24 month time horizon of rate shocks on pretax net interest income, we also perform EVE analyses. EVE represents the present value of all asset cash flows minus the present value of all liability cash flows. EVE change results are compared to a base case to determine the impact that market rate changes may have on our EVE. As with rate shock analyses on pretax net interest income, EVE analyses incorporate management assumptions regarding prepayment behavior of fixed rate loans and securities with optionality and the behavior and value of non-maturity deposit products. S&T policy guidelines limit the change in EVE using rate shocks in increments of +/- 100 basis points. Policy guidelines define the percentage change in EVE by graduated risk tolerance levels of minimal, moderate and high.

The table below reflects the rate shock analyses results for the 1-12 and 13-24 month periods of pretax net interest income and EVE.

The results from the rate shock analyses on net interest income are generally consistent with having an asset sensitive balance sheet. Having an asset sensitive balance sheet means more assets than liabilities will reprice during the measured time frames. The implications of an asset sensitive balance sheet will differ depending upon the change in market interest rates. For example, with an asset sensitive balance sheet in a declining interest rate environment, more assets than liabilities will decrease in rate. This situation could result in a decrease in net interest income and operating income. Conversely, with an asset sensitive balance sheet in a rising interest rate environment, more assets than liabilities will increase in rate. This situation could result in an increase in net interest income and operating income.

Our rate shock analyses remain relatively unchanged in the percentage change in pretax net interest income in the rates up scenarios when comparing June 30, 2025 to December 31, 2024. The percentage change in pretax net interest income in the rates down scenarios has improved when comparing June 30, 2025 to December 31, 2024 primarily due to updates of our deposit beta and loan prepayment assumptions. Our EVE analyses show an improvement in the rates up scenarios and a decline in the rates down scenarios when comparing June 30, 2025 to December 31, 2024 primarily due to updated deposit retention assumptions.

**S&T BANCORP, INC. AND SUBSIDIARIES**

In addition to rate shocks and EVE analyses, we perform a market risk stress test at least annually. The market risk stress test includes sensitivity analyses and simulations. Sensitivity analyses are performed to help us identify which model assumptions cause the greatest impact on pretax net interest income. Sensitivity analyses may include changing prepayment behavior of loans and securities with optionality and the impact of interest rate changes on non-maturity deposit products. Simulation analyses may include the potential impact of rate changes other than the policy guidelines, yield curve shape changes, significant balance mix changes and various growth scenarios.

**Item 4. CONTROLS AND PROCEDURES**

**Evaluation of Disclosure Controls and Procedures**

Under the supervision and with the participation of S&T's Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO (its principal executive officer and principal financial officer, respectively), management has evaluated the effectiveness of the design and operation of S&T's disclosure controls and procedures as of June 30, 2025. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time periods required by the Securities and Exchange Commission, or the SEC, and that such information is accumulated and communicated to S&T's management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.

Based on and as of the date of such evaluation, our CEO and CFO concluded that the design and operation of our disclosure controls and procedures were effective in all material respects, as of the end of the period covered by this report.

**Changes in Internal Control over Financial Reporting**

During the quarter ended June 30, 2025, there were no changes made to S&T's internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that materially affected, or are reasonably likely to materially affect, S&T's internal control over financial reporting.

<sup>(</sup><sup>1)</sup> *On May 13, 2025, our Board of Directors authorized an extension of its $50 million share repurchase plan. The new repurchase authorization will expire July 31, 2026. This repurchase authorization permits S&T to repurchase shares of S&T's common stock from time to time through a combination of open market and privately negotiated repurchases up to the authorized $50 million aggregate value of S&T's common stock. The specific timing, price and quantity of repurchases will be at the discretion of S&T and will depend on a variety of factors, including general market conditions, the trading price of the common stock, legal and contractual requirements and S&T's financial performance. The repurchase plan does not obligate S&T to repurchase any particular number of shares. S&T expects to fund any repurchases from cash on hand and internally generated funds. Any share repurchases will not begin until permissible under applicable laws.*
