If S&T's assets cross the $10 billion threshold, we will be subject to different and additional regulations than those described below.

In addition, proposals to change the laws and regulations governing the banking industry are frequently raised in Congress, in state legislatures and before the various bank regulatory agencies that may impact S&T. Bank regulatory agencies may issue policy statements, interpretive letters and similar written guidance applicable to S&T or S&T Bank. Such initiatives to change the laws and regulations may include proposals to expand or contract the powers of bank holding companies and depository institutions or proposals to substantially change the financial institution regulatory system. Any such legislation could change bank statutes and our operating environment in substantial and unpredictable ways. If enacted, such legislation could affect how S&T and S&T Bank operate and could significantly increase costs, impede the efficiency of internal business processes, limit our ability to pursue business opportunities in an efficient manner or affect the competitive balance among banks, credit unions and other financial institutions, any of which could materially and adversely affect our business, financial condition and results of operations. The likelihood and timing of any changes and the impact such changes might have on S&T is impossible to determine with any certainty.

***Regulation of S&T***

We are a bank holding company subject to regulation under the BHCA and the examination and reporting requirements of the Federal Reserve and have elected to be a financial holding company. Under the BHCA, a financial holding company is restricted in the types of activities in which it may engage and subject to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of laws and regulations.

In general, the BHCA limits the business of bank holding companies to banking, managing, or controlling banks and other activities that the Federal Reserve has determined to be closely related to banking. Bank holding companies that qualify and elect to become financial holding companies, such as S&T, may engage in any activity, or acquire and retain the shares of a company engaged in any activity, that is either financial in nature or incidental to such financial activity (as determined by the Federal Reserve in consultation with the Secretary of the Treasury), or complementary to a financial activity, and that does not pose a substantial risk to the safety and soundness of depository institutions or the financial system (as solely determined by the Federal Reserve). The BHCA identifies several activities as "financial in nature" including, among others, securities underwriting; dealing and market making; sponsoring mutual funds and investment companies; insurance underwriting and sales agency; investment advisory activities; merchant banking activities and activities that the Federal Reserve has determined to be closely related to banking. Banks may also engage in, subject to limitations on investment, activities that are financial in nature, other than insurance underwriting, insurance company portfolio investment, real estate development and real estate investment, through a financial subsidiary of the bank, if the bank is "well-capitalized," "well-managed" and has at least a "satisfactory" Community Reinvestment Act, or CRA, rating.

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

In order to maintain our status as a financial holding company, we must remain "well-capitalized" and "well-managed" and the depository institutions controlled by us must remain "well-capitalized," "well-managed" (as defined in federal law) and have at least a "satisfactory" CRA rating. Refer to Note 23. Regulatory Matters to the consolidated financial statements contained in Part II, Item 8 of this Report for information concerning the current capital ratios of S&T and S&T Bank. If S&T or S&T Bank fail to continue to meet these requirements, we could be subject to restrictions on new activities and acquisitions, and/or be required to cease and possibly divest operations that conduct existing activities that are not permissible for a bank holding company that is not a financial holding company. Additionally, the Federal Reserve could impose corrective capital and managerial requirements and activity restrictions on us if we cease to be "well-capitalized" or "well managed."

As a financial holding company, we are expected under statutory and regulatory provisions to serve as a source of financial and managerial strength to our subsidiary bank. A financial holding company is also expected to commit resources, including capital and other funds, to support its subsidiary bank. The Federal Reserve may require a bank holding company to make capital injections into a troubled subsidiary bank and may charge the bank holding company with engaging in unsafe and unsound practices if it fails to commit resources to such a subsidiary bank, or if it undertakes actions that the Federal Reserve believes might jeopardize the bank holding company's ability to commit resources to such subsidiary bank. Capital loans by banking holding companies to its subsidiary banks would be subordinate in right of payment to deposits and certain other debts of the subsidiary bank. In the event of bankruptcy, any commitment by a bank holding company to a federal bank regulatory agency to maintain the capital of a subsidiary bank would be assumed by the bankruptcy trustee and entitled to a priority of payment.

The BHCA requires that a financial holding company obtain the prior approval of the Federal Reserve before (i) acquiring direct or indirect ownership or control of more than 5 percent of the voting shares of any additional bank or bank holding company, (ii) taking any action that causes an additional bank or bank holding company to become a subsidiary of the financial holding company, or (iii) merging or consolidating with any other bank holding company. No prior regulatory approval is required for a financial holding company to acquire a company, other than a bank or savings association, engaged in activities that are financial in nature or incidental to activities that are financial in nature, as determined by the Federal Reserve, unless the total consolidated assets to be acquired exceed $10 billion. Federal law restricts the amount of voting stock of a bank holding company and a bank that a person may acquire without the prior approval of banking regulators. Federal law also imposes restrictions on acquisitions of stock in a bank holding company. Under the federal Change in Bank Control Act and the regulations thereunder, a person or group must give advance notice to the Federal Reserve before acquiring control of any bank holding company, such as S&T, and the FDIC before acquiring control of any state-chartered non-member bank, such as S&T Bank. Upon receipt of such notice, the bank regulatory agencies may approve or disapprove the acquisition. The Change in Bank Control Act creates a rebuttable presumption of control if a member or group acquires a certain percentage or more of a bank holding company's or bank's voting stock, or if one or more other control factors set forth in the Act are present. As a result, a person or entity generally must provide prior notice to the Federal Reserve before acquiring the power to vote 10 percent or more of S&T's outstanding common stock.

***S&T Bank***

As a Pennsylvania-chartered, FDIC-insured non-member commercial bank, S&T Bank is subject to the supervision and regulation of the PA DOBS and the FDIC. We are also subject to various requirements and restrictions under federal and state law, including requirements to maintain reserves against deposits, restrictions on the types, amount and terms and conditions of loans that may be granted and limits on the types of other activities in which S&T Bank may engage and the investments it may make.

S&T Bank is subject to affiliate transaction rules in Sections 23A and 23B of the Federal Reserve Act as implemented by the Federal Reserve's Regulation W, that limit the amount of transactions between itself and S&T or any other company or entity that controls or is under common control with any company or entity that controls S&T Bank, including for most purposes any financial or depository institution subsidiary of S&T Bank. Under these provisions, "covered" transactions, including making loans, purchasing assets, issuing guarantees and other similar transactions, between a bank and its parent company or any other affiliate, generally are limited to 10 percent of the bank subsidiary's capital and surplus, and with respect to all transactions with affiliates, are limited to 20 percent of the bank subsidiary's capital and surplus. Loans and extensions of credit from a bank to an affiliate generally are required to be secured by eligible collateral in specified amounts, and in general all affiliated transactions must be on terms consistent with safe and sound banking practices. Furthermore, in general, transactions between a bank and its affiliates must be on terms and conditions that are at least as favorable to the bank as the terms that would apply in comparable transactions between the bank and a third party. Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, expanded the affiliate transaction rules to broaden the definition of "covered transactions" to include securities, borrowing or lending, repurchase and reverse repurchase agreements and certain derivative transactions. The Act also strengthened collateral requirements and significantly limited the Federal Reserve's authority to grant exemptions from these rules.

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

Federal law also constrains the types and amounts of loans that S&T Bank may make to its executive officers, directors and principal shareholders. Among other things, these loans are limited in amount, must be approved by S&T Bank's board of directors in advance and must be on terms and conditions as favorable to the bank as those available to an unrelated person. The Dodd-Frank Act strengthened restrictions on loans to insiders and expanded the types of transactions subject to the various limits to include credit exposure arising from a derivative transaction, a repurchase or reverse repurchase agreement and a securities lending or borrowing transaction. The Dodd-Frank Act also placed restrictions on certain asset sales to and from an insider to an institution, including requirements that such sales be on market terms and, in certain circumstances, approved by the institution's board of directors.

Pursuant to Section 18(c) of the FDIA, more commonly known as the Bank Merger Act, or BMA, prior written approval from a bank's primary federal regulator is required before any insured depository institution may consummate a merger transaction which includes a merger, consolidation, assumption of deposit liabilities and certain asset transfers between or among two or more institutions. Prior written approval of a bank's primary federal regulator is also required for merger transactions between or among affiliated institutions, as well as for merger transactions between or among non-affiliated institutions. Transactions that do not involve a transfer of deposit liabilities typically do not require prior approval under the BMA, unless the transaction involves the acquisition of all or substantially all of an institution's assets. In September 2024, the FDIC adopted a final rule amending its procedures for reviewing applications under the BMA and adding a policy statement on the FDIC's substantive approach to evaluating bank mergers under the BMA, which, among other things, eliminated certain expedited review procedures and streamlined application processes. However, on May 20, 2025, the FDIC approved the rescission of its 2024 policy statement and reinstated its 2008 policy statement while it conducts a broader reevaluation of its bank merger review process. These actions reflect regulatory efforts to reduce procedural uncertainty and burden in the bank merger review process. The statutory framework underlying the BMA has not been materially changed by recent legislation, and agencies continue to exercise broad discretion in merger evaluation on a case-by-case basis. Proposed changes to bank merger policy, including oversight and application procedures, may arise from regulatory proposals or Congressional interest and could affect the timing, complexity or conditions of merger approvals.

In September 2024, the Department of Justice, or DOJ, withdrew its 1995 Bank Merger Guidelines and issued the 2024 Banking Addendum to 2023 Merger Guidelines, or the 2024 Banking Addendum. The DOJ clarified that it would assess competition considerations in connection with bank and bank holding company mergers using its 2023 Merger Guidelines which is the general merger review framework the DOJ now uses to evaluate transactions in all segments of the economy, and 2024 Banking Addendum. The 2024 Banking Addendum provides guidance on how the DOJ will assess competition in the context of bank and bank holding company mergers. An analysis under the 2023 Merger Guidelines and 2024 Banking Addendum may include consideration of theories of harm and relevant markets not considered under the 1995 Bank Merger Guidelines which focused primarily on concentrations of deposits and branches. Notwithstanding the actions of the FDIC in 2025, transactions that satisfy traditional banking regulator approval standards may nonetheless face extended DOJ review, additional information requests, conditions or challenges.

***Supervision, Examination and Enforcement***

The Federal Reserve and FDIC have broad supervisory, examination and enforcement authority with regard to bank holding companies and banks, including the power to impose nonpublic supervisory agreements, issue cease and desist or removal orders, impose fines and other civil and criminal penalties, initiate injunctive actions, terminate deposit insurance and appoint a conservator or receiver. In general, these actions may be initiated for violations of laws and regulations, as well as engagement in unsafe and unsound practices, and some of these actions also may be taken against an "institution affiliated party" as defined in the law. Specifically, the regulators may direct a bank holding company or bank to, among other things, increase its capital, sell subsidiaries or other assets, limit its dividends and distributions, restrict its growth or remove officers and directors. Supervision and examinations are confidential, and the outcomes of these actions may not be made public. In addition, if our total consolidated assets exceed $10 billion, we may be subject to additional supervision by the Consumer Financial Protection Bureau, or CFPB, with respect to consumer protection laws and regulations.

On August 7, 2025, Executive Order 14331,"Guaranteeing Fair Banking Access for All Americans," was issued directing federal banking agencies to identify and address "politicized or unlawful" denial of financial services based on constitutionally or statutorily protected beliefs, affiliations, or political views. In response, the Small Business Administration, or SBA, required certain certifications from SBA lending program participants, and the FDIC conducted supervisory reviews of policies and practices at certain FDIC-supervised institutions.

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

In October 2025, the federal bank regulators issued a proposed rule to limit reputation risk as a factor in their supervisory frameworks. Under the proposed rule, the agencies would be prohibited from criticizing or taking adverse action against a financial institution based on reputation risk. Certain states have also enacted or proposed "fair access" laws that may affect how financial institutions approach account opening, account termination and related relationship decisions. These developments may result in evolving supervisory expectations, examination practices or compliance requirements applicable to S&T and its affiliates and could increase operational, compliance or legal complexity, including where requirements overlap with or potentially conflict with other legal or risk-management obligations.

***Insurance of Accounts; Depositor Preference***

The deposits of S&T Bank are insured up to applicable limits per insured depositor by the DIF, as administered by the FDIC. The Dodd-Frank Act codified FDIC deposit insurance coverage per separately insured depositor for all account types at $250,000.

The DIF is funded mainly through quarterly assessments on insured depository institutions, such as S&T Bank, and provides insurance coverage for certain deposits up to this maximum amount. As an FDIC-insured bank, S&T Bank is subject to FDIC insurance assessments which are imposed based upon the calculated risk the institution poses to the DIF. S&T Bank's assessment is determined each quarter in accordance with the FDIC's standardized risk-based methodology by multiplying its assessment rate by its assessment base. The assessment base is calculated as a percentage of average consolidated total assets less average tangible equity during the assessment period. Under the current assessment system, for an institution with less than $10 billion in assets, assessment rates are determined based on a combination of financial ratios and CAMELS (capital adequacy, asset quality, management, earnings, liquidity and sensitivity) composite ratings. The assessment rate schedule can change from time to time, at the discretion of the FDIC, subject to certain limits. Under the current system, premiums are assessed quarterly.

As part of its semiannual update of the restoration plan established by the FDIC to facilitate restoration of the reserve ratio of the DIF to the statutory minimum in the mandated time frame, the FDIC adopted a final rule in October 2022. The new rule, applicable to all insured depository institutions, increased the initial base deposit insurance assessment rate schedules uniformly by 2 basis points, beginning in the first quarterly assessment period of 2023 (January 1 through March 31, 2023). The increase in assessment rate schedules was intended to increase the likelihood that the reserve ratio of the DIF reaches the statutory minimum of 1.35 percent by the statutory deadline of September 30, 2028. The change in assessment rates was further intended to support the growth of the DIF in progressing toward the 2 percent Designated Reserve Ratio, or DRR, established by the FDIC. The FDIC has indicated that the new assessment rate schedules will remain in effect unless and until the DRR meets or exceeds 2 percent, absent further FDIC action. Under the new rule, the total base assessment rates on an annualized basis range from 2.5 basis points for certain "well-capitalized," "well-managed" banks, with the highest ratings, to 42 basis points for complex institutions posing the most risk to the DIF compared to the 2022 rates that ranged from 1.5 to 40.

In addition to regular assessments, the FDIC has authority to impose special assessments on insured depository institutions, including to recover losses to the DIF associated with bank failures. In November 2023, the FDIC finalized a special assessment to recover DIF losses related to the closures of Silicon Valley Bank and Signature Bank. The assessment applies only to institutions with more than $5 billion in uninsured deposits as of December 31, 2022. Because S&T Bank's uninsured deposits were below this threshold, the assessment does not apply to S&T.

The FDIC may terminate the deposit insurance of any insured depository institution if it determines, after hearing that the institution has engaged in unsafe or unsound practices, that the institution is in an unsafe or unsound condition to continue operations or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC or the Federal Reserve. It also may suspend deposit insurance temporarily during the hearing process if the institution has no tangible capital. If insurance of accounts is terminated, the accounts at the institution at the time of termination, less subsequent withdrawals, will continue to be insured for a period of six months to two years, as determined by the FDIC.

Under federal law, deposits and certain claims for administrative expenses and employee compensation against insured depository institutions are afforded a priority over other general unsecured claims against such an institution, including federal funds and letters of credit, in the liquidation or other resolution of such an institution by a receiver. Such priority creditors would include the FDIC.

***Capital***

S&T and S&T Bank are required under federal law to maintain certain minimum capital levels based on ratios of capital to total assets and capital to risk-weighted assets. The Federal Reserve and the FDIC have issued substantially similar minimum risk-based and leverage capital rules applicable to the banking organizations they supervise. These capital ratios represent regulatory minimums, and the Federal Reserve and FDIC may determine that a banking organization, based on its size, complexity, risk profile, growth plans or overall condition, must maintain capital levels in excess of the minimum requirements in order to operate in a safe and sound manner. In assessing capital adequacy, banking regulators consider a variety of qualitative and quantitative factors, including concentrations of credit risk, exposure to interest rate risk, liquidity risk, operational and market risks, risks arising from non-traditional activities and management's ability to identify, measure, monitor and control those risks.

Under the applicable capital rules, S&T and S&T Bank are subject to the following risk-based capital ratios: a common equity tier 1, or CET1, risk-based capital ratio, a Tier 1 risk-based capital ratio, which includes CET1 and additional Tier 1 capital and a total capital ratio which includes Tier 1 and Tier 2 capital. CET1 is primarily comprised of the sum of common stock instruments and related surplus net of treasury stock, retained earnings and certain qualifying minority interests, less certain adjustments and deductions, including with respect to goodwill, intangible assets, mortgage servicing assets and deferred tax assets subject to temporary timing differences. Additional Tier 1 capital is primarily comprised of noncumulative perpetual preferred stock, tier 1 minority interests and grandfathered trust preferred securities, if applicable. Tier 2 capital consists of instruments disqualified from Tier 1 capital, including qualifying subordinated debt, certain trust preferred securities, other preferred stock and certain hybrid capital instruments and a limited amount of loan loss reserves up to a maximum of 1.25 percent of risk-weighted assets, subject to certain eligibility criteria.

The capital rules require a minimum CET1 risk-based capital ratio of 4.5 percent, a minimum overall Tier 1 risk based capital ratio of 6.0 percent, and a total risk-based capital ratio of 8.0 percent. In addition, the capital rules require a capital conservation buffer of 2.5 percent above each of the minimum capital ratio requirements (CET1, Tier 1, and total risk-based capital), which must be met for a bank or bank holding company to be able to pay dividends, engage in share buybacks or make discretionary bonus payments to executive management without automatic restrictions. The capital conservation buffer is 2.50 percent, so a banking organization needs to maintain a CET1 capital ratio of at least 7 percent, a total Tier 1 capital ratio of at least 8.5 percent and a total risk-based capital ratio of at least 10.5 percent or it would be subject to restrictions on capital distributions and discretionary bonus payments to its executive management.

The leverage capital ratio, which serves as a minimum capital standard, is the ratio of Tier 1 capital to quarterly average total assets, less goodwill and other disallowed intangible assets. The required minimum leverage ratio for all banks and bank holding companies is 4 percent.

To be well-capitalized, we must maintain the following capital ratios:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● CET1 risk-based capital ratio of 6.5 percent or greater;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Tier 1 risk-based capital ratio of 8.0 percent or greater;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Total risk-based capital ratio of 10.0 percent or greater; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Tier 1 leverage ratio of 5.0 percent or greater.

Failure to be well-capitalized or to meet minimum capital requirements could result in certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have an adverse material effect on our operations or financial condition. For example, only a well-capitalized depository institution may accept brokered deposits without prior regulatory approval. Failure to be well-capitalized or to meet minimum capital requirements could also result in restrictions on S&T's or S&T Bank's ability to pay dividends or otherwise distribute capital or to receive regulatory approval of applications or other restrictions on its growth.

On December 31, 2025, S&T's and S&T Bank's regulatory capital ratios were above the well-capitalized standards and met the fully phased-in capital conservation buffer.

***Payment of Dividends***

S&T is a legal entity separate and distinct from its banking and other subsidiaries. A substantial portion of our revenues consist of dividend payments we receive from S&T Bank. The payment of common dividends by S&T is subject to certain requirements and limitations of Pennsylvania law. S&T Bank, in turn, is subject to federal and state laws and regulations that limit the amount of dividends it can pay to S&T. In addition, both S&T and S&T Bank are subject to various general regulatory policies relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The Federal Reserve has indicated that banking organizations should generally pay dividends only if (i) the organization's net income available to common shareholders over the past year has been sufficient to fully fund the dividends, (ii) the prospective rate of earnings retention appears consistent with the organization's capital needs, asset quality and overall financial condition and (iii) the organization will continue to meet minimum capital adequacy ratios. The policy also provides that a banking organization should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in a material adverse change to the bank holding company's capital structure. Bank holding companies also are required to consult with the Federal Reserve before redeeming or repurchasing capital instruments when the bank holding company is experiencing financial weaknesses. Additionally, the Federal Reserve could prohibit or limit the payment of dividends by a bank holding company if it determines that payment of the dividend would constitute an unsafe or unsound practice.

Thus, under certain circumstances based upon our financial condition, our ability to declare and pay quarterly dividends may require consultation with the Federal Reserve and may be prohibited by applicable Federal Reserve guidance.

***Safety and Soundness Regulations***

There are a number of obligations and restrictions imposed on bank holding companies such as us and our depository institution subsidiary by federal law and regulatory policy. These obligations and restrictions relate to internal controls, risk management, information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth and compensation, fees and benefits. These guidelines in general require appropriate systems and practices to identify and manage specified risks and exposures. These obligations and restrictions are designed to reduce potential loss exposure to the FDIC's DIF in the event an insured depository institution becomes in danger of default or is in default. Under current federal law, for example, the federal banking agencies possess broad powers to take prompt corrective action to resolve problems of insured depository institutions. The extent of these powers depends upon whether the institution in question is "well-capitalized," "adequately capitalized," "undercapitalized," "significantly undercapitalized" or "critically undercapitalized," as defined by the law. As of December 31, 2025, S&T Bank was classified as "well-capitalized." Refer to the above section titled Capital within this Item 1. Business section for capital requirements. The classification of depository institutions is primarily for the purpose of applying the federal banking agencies' prompt corrective action provisions and is not intended to be and should not be interpreted as a representation of overall financial condition or prospects of any financial institution.

***Lending Standards and Guidance***

The federal banking agencies have adopted uniform regulations prescribing standards for extensions of credit that are secured by liens on, or interests in, real estate or made for the purpose of financing permanent improvements to real estate. Under these regulations, all insured depository institutions, including S&T Bank, are required to adopt and maintain written policies that establish appropriate limits and standards for such extensions of credit. These policies must address, among other things, loan portfolio diversification standards, prudent underwriting standards (including clear and measurable loan-to-value limits), loan administration procedures and documentation, approval and reporting requirements. S&T Bank's real estate lending policies are required to reflect consideration of the federal banking regulators' Interagency Guidelines for Real Estate Lending Policies.

The federal banking agencies have also jointly issued supervisory guidance on Concentrations in Commercial Real Estate Lending (the "Guidance"). The Guidance defines commercial real estate loans to include exposures secured by raw land, land development and construction (including one-to-four family residential construction), multifamily property and non-farm nonresidential property where the primary or a significant source of repayment is derived from rental income associated with the property (generally defined as loans for which 50 percent or more of the source of repayment is derived from third-party, non-affiliated rental income) or from the proceeds of the sale, refinancing or permanent financing of the property.

The Guidance provides that insured depository institutions should maintain appropriate processes to identify, monitor and control risks associated with concentrations in commercial real estate lending. Where concentrations are present, management is expected to employ heightened risk management practices which may include enhanced board and management oversight and strategic planning, portfolio management, underwriting standards, risk assessment and monitoring through market analysis and stress testing and the maintenance of capital levels appropriate to support the level of commercial real estate lending. These heightened risk management practices may also include enhanced internal controls, portfolio stress testing, risk exposure limits, compensation and incentive programs and, where appropriate, higher allowances for credit losses.

***Prompt Corrective Action***

The federal banking agencies' prompt corrective action powers, which increase depending upon the degree to which an institution is undercapitalized, can include, among other things, requiring an insured depository institution to adopt a capital restoration plan which cannot be approved unless guaranteed by the institution's parent company; placing limits on asset growth and restrictions on activities, including restrictions on transactions with affiliates; restricting the interest rates the institution may pay on deposits; restricting the institution from accepting brokered deposits; prohibiting the payment of principal or interest on subordinated debt; prohibiting the holding company from making capital distributions, including payment of dividends, without prior regulatory approval; and, ultimately, appointing a receiver for the institution.

The federal banking agencies have also adopted guidelines prescribing safety and soundness standards relating to internal controls and information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, fees and compensation and benefits. In general, the guidelines require appropriate systems and practices to identify and manage specified risks and exposures. The guidelines prohibit excessive compensation as an unsafe and unsound practice and characterize compensation as excessive when the amounts paid are unreasonable or disproportionate to the services performed by an executive officer, employee, director or principal shareholder. In addition, the agencies have adopted regulations that authorize, but do not require, an agency to order an institution that has been given notice by an agency that it is not in compliance with any of such safety and soundness standards to submit a compliance plan. If, after being so notified, an institution fails to submit an acceptable compliance plan, the agency must issue an order directing action to correct the deficiency and may issue an order directing other actions of the types to which an "undercapitalized" institution is subject under the prompt corrective action provisions described above.

***Regulatory Enforcement Authority***

The enforcement powers available to federal banking agencies are substantial and include, among other things and in addition to other powers described herein, the ability to assess civil money penalties and impose other civil and criminal penalties, to issue cease-and-desist or removal orders, to appoint a conservator to conserve the assets of an institution for the benefit of its depositors and creditors and to initiate injunctive actions against banks and bank holding companies and "institution affiliated parties," as defined in the Federal Deposit Insurance Act, or FDIA. In general, these enforcement actions may be initiated for violations of laws and regulations, and engagement in unsafe or unsound practices. Other actions or inactions may provide the basis for enforcement action, including misleading or untimely reports filed with regulatory authorities. At the state level, the PA DOBS also has broad enforcement powers over S&T Bank, including the power to impose fines and other penalties and to appoint a conservator or receiver.

***Interstate Banking and Branching***

The BHCA currently permits bank holding companies from any state to acquire banks and bank holding companies located in any other state, subject to certain conditions, including certain nationwide and state-imposed deposit concentration limits. In addition, because of changes to law made by the Dodd-Frank Act, S&T Bank may now establish de novo branches in any state to the same extent that a bank chartered in that state could establish a branch.

***Fair Lending and Consumer Protection Laws***

In connection with its lending activities, S&T Bank is subject to a number of state and federal laws and regulations designed to protect consumers and promote lending to various sectors of the economy and population. The federal laws include, among others, the Equal Credit Opportunity Act, the Truth-in-Lending Act, the Truth-in-Savings Act, the Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act, the Fair Credit Reporting Act, Fair Housing Act and the Community Reinvestment Act, or CRA. In addition, federal rules require disclosure of privacy policies to consumers.

Fair lending laws prohibit discrimination in the lending practices, and include the Equal Credit Opportunity Act and the Fair Housing Act which outlaw discrimination in credit transactions and residential real estate on the basis of prohibited factors including, among others, race, color, national origin, sex and religion. If a pattern or practice of lending discrimination is alleged by a regulator, then that agency is required to refer the matter to the DOJ for investigation. S&T Bank is required to have a fair lending program that is of sufficient scope to monitor the inherent fair lending risk of the institution and ensure compliance with all applicable fair lending laws and regulations.

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

In addition, the Dodd-Frank Act provides that the amount of any interchange fee charged for electronic debit transactions by debit card issuers having assets over $10 billion must be reasonable and proportional to the actual cost of a transaction to the issuer. The Federal Reserve has adopted a rule, Regulation II, which limits the maximum permissible interchange fees that such issuers can receive for an electronic debit transaction. Regulation II was effective on October 1, 2011 and amended on October 3, 2022 to require debit card issuers to provide at least two unaffiliated payment card networks to process card-not-present debit card transactions. Regulation II does not apply to a bank that, together with its affiliates, has less than $10 billion in assets, which includes S&T. In addition, their future application is subject to uncertainty. Ongoing litigation has challenged the Federal Reserve's implementation of the interchange fee cap, and while no statutory changes have been enacted, adverse judicial outcomes or future regulatory action could modify or invalidate the current framework. The Federal Reserve has not finalized any amendments to Regulation II, and institutions below $10 billion in consolidated assets continue to qualify for the small-issuer exemption. However, as S&T grows, it may become subject to Regulation II, depending on the outcome of ongoing litigation and any applicable rule changes. Additionally, in February of 2026, a federal court in Illinois partially upheld a first-of-its-kind state law restricting interchange fees. This Illinois Interchange Fee Prohibition Act goes into effect on July 1, 2026. The majority of our customers are not located in Illinois, however, there may be similar state laws promulgated over time.

In March 2023, the CFPB issued the "Small Business Lending Rule" to implement Section 1071 of the Dodd-Frank Act for the stated purpose of increasing transparency in small business lending, promoting economic development, and combating unlawful discrimination. Under the Small Business Lending Rule, covered lenders, including S&T Bank, are required to collect and report information about the small business credit applications they receive, including geographic and demographic data, lending decisions and the price of credit. The Small Business Lending Rule has been subject to extensive litigation and court stays have extended the compliance deadlines for certain entities involved in the litigation. As a result, the CFPB announced on April 30, 2025, that it will not prioritize enforcement or supervision of the Small Business Lending Rule for entities not covered by the stay. On June 18, 2025, the CFPB issued an interim final rule to extend compliance deadlines by approximately one year which was finalized on October 2, 2025. In addition, on November 13, 2025, the CFPB proposed significant changes to the Small Business Lending Rule that would exclude certain credit from the definition of covered credit transaction, increase loan origination thresholds for covered companies, change revenue thresholds for the definition of small businesses, remove certain data points from reporting and further extend the compliance date to January 1, 2028 for all covered financial institutions.

In October 2024, the CFPB finalized its "Open Banking Rule" to implement Section 1033 of the Dodd-Frank Act, which would require certain entities, including S&T and S&T Bank, to, among other things, make available to a consumer, upon request, information in its control or possession concerning the consumer financial product or service that the consumer obtained from that entity. The Open Banking Rule has been subject to extensive litigation since its adoption. As part of that litigation, on May 23, 2025, the CFPB stated in a litigation status report that the Open Banking Rule is unlawful. As a result, litigation was stayed while the CFPB conducted new rulemaking process. On August 22, 2025, the CFPB released an advanced notice of proposed rulemaking soliciting public comment to the Open Banking Rule.

S&T Bank is continuing to monitor and evaluate the impact of the Small Business Lending Rule and Open Banking Rule, though compliance may require operational, technology and policy changes, may increase S&T Bank's compliance costs and could subject S&T Bank to heightened litigation and enforcement risk.

***Community Reinvestment Act***

The CRA requires the appropriate federal banking agency, in connection with its examination of a bank, to assess the bank's record in meeting the credit needs of the communities served by the institution, including low- and moderate-income, or LMI, borrowers and neighborhoods. The CRA is designed to encourage regulated banks to help meet the credit needs of the local communities in which they are chartered. The Federal Reserve, the FDIC and the OCC implement the CRA through their CRA regulations which establish the framework for how the agencies assess a bank's record of helping to meet the credit needs of the communities that they serve, including LMI neighborhoods, consistent with safe and sound operations. Furthermore, such assessment is required of any bank that has applied, among other things, to merge or consolidate with or acquire the assets or assume the liabilities of an insured depository institution, or to open or relocate a branch office. In the case of a bank holding company, including a financial holding company, applying for approval to acquire a bank or bank holding company, the Federal Reserve will assess the record of each subsidiary bank of the applicant bank holding company in considering the application. Under the CRA, institutions are assigned a rating of "outstanding," "satisfactory," "needs to improve" or "unsatisfactory." S&T Bank was rated "satisfactory" in its most recent CRA performance evaluation.

On October 24, 2023, the FDIC, OCC and Federal Reserve jointly issued a final rule to the CRA designed to strengthen and modernize the regulations implementing the CRA. The changes are designed to encourage banks to expand access to credit, investment and banking services in LMI communities, adapt to changes in the banking industry, including mobile and internet banking, provide greater clarity and consistency in the application of the CRA regulations and tailor CRA evaluations and data collection to bank size and type. Most of the final rule's requirements were applicable beginning in January 2026, while the remaining requirements, including data reporting requirements, will be applicable in January 2027. The 2023 CRA final rule has been subject to legal challenge, and its effectiveness and implementation have been enjoined by a federal court. In light of the foregoing, FDIC, OCC and Federal Reserve jointly issued a proposal on July 16, 2025, to rescind the final CRA final rule issued in October 2023 and replace it with the prior CRA regulations that were originally adopted by the agencies in 1995, with certain technical amendments. Until any new CRA rule becomes effective, we expect to continue to be evaluated under the CRA regulations currently in effect. Any future changes to the CRA framework (including changes to assessment areas, evaluation methods, data collection or reporting requirements and the standards applied in connection with regulatory applications) could increase our compliance costs and may affect our ability to obtain regulatory approvals.

With respect to consumer protection, the Dodd-Frank Act created the CFPB which took over rulemaking responsibility on July 21, 2011 for the principal federal consumer financial protection laws, such as those identified above. Institutions that have assets of $10 billion or less, such as S&T Bank, are subject to the rules established by the CFPB, but will continue to be supervised in this area by their state and primary federal regulators which in the case of S&T Bank is the FDIC. S&T Bank continues to comply with all applicable consumer protection laws and regulations.

***Anti-Money Laundering Rules***

S&T Bank is subject to the Bank Secrecy Act, or BSA, its implementing regulations and other anti-money laundering, or AML, laws and regulations, including the USA Patriot Act of 2001. Among other things, these laws and regulations require S&T Bank to take steps to prevent the bank from being used to facilitate the flow of illegal or illicit money, to report large currency transactions and to file suspicious activity reports. S&T Bank is also required to develop and implement a comprehensive AML/Countering The Financing Of Terrorism, or CFT, compliance program. Banks must also have in place appropriate "know your customer", or KYC, policies and procedures which includes requirements to (1) identify and verify, subject to certain exceptions, the identity of the beneficial owners of all legal entity customers at the time a new account is opened, and (2) include in its AML/CFT program, risk-based procedures for conducting ongoing customer due diligence, which are to include procedures that (a) assist in understanding the nature and purpose of customer relationships for the purpose of developing a customer risk profile, and (b) require ongoing monitoring to identify and report suspicious transactions and, on a risk basis, to maintain and update customer information. Violations of these requirements can result in substantial civil and criminal sanctions. In addition, provisions of the USA Patriot Act of 2001 require the federal financial institution regulatory agencies to consider the effectiveness of a financial institution's AML/CFT activities when considering applications for bank mergers and bank holding company acquisitions.

In June 2025, the federal bank regulators in coordination with the Financial Crimes Enforcement Network, or FinCEN, issued an exemption order from the customer identification program requirement for banks to collect Taxpayer Identification Numbers (TINs) directly from customers before opening accounts. The exemption allows banks to obtain TIN information from third-party sources, provided they still comply with other Customer Identification Program, or CIP, requirements, including risk-based procedures to verify customer identities. This exemption aims to address evolving customer interaction methods and privacy concerns, especially related to identity theft risks. Banks are not required to use this alternative collection method but may choose to do so if it aligns with their risk-based approach to customer verification.

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

The Anti-Money Laundering Act of 2020, enacted on January 1, 2021 as part of the National Defense Authorization Act, or AMLA, amends the BSA but does not directly impose new requirements on banks. However, AMLA requires the U.S. Treasury Department to, among other things, issue National Anti-Money Laundering and Countering the Financing of Terrorism Priorities and implementing regulations, and conduct studies and issue regulations that may, over the next few years, significantly alter certain due diligence, recordkeeping and reporting requirements that the BSA and its implementing regulations impose on banks. AMLA also contains provisions that increase penalties for violations of the BSA and includes whistleblower incentives, both of which could increase regulatory enforcement against banks. Implementation of AMLA is ongoing and is anticipated to impact S&T Bank's AML compliance program.

In an effort to increase transparency in the U.S. financial system and prevent shell entities from being used to launder money or hide assets, AMLA includes the Corporate Transparency Act, or CTA, which requires the U.S. Treasury Department's Financial Crimes Enforcement Network, or FinCEN, to, among other things, establish a national beneficial ownership information registry. In September 2022, FinCEN issued the final Beneficial Ownership Information Reporting Requirements rule, or BOI Reporting Rule, which effective January 1, 2024, requires certain "reporting companies" to file beneficial ownership information reports with FinCEN that will be stored in the national beneficial ownership registry and will detail the reporting company's beneficial owners. In December 2023, FinCEN issued the final Beneficial Ownership Information Access and Safeguards rule - the second of three rulemakings that would implement the CTA - which governs access to the national beneficial ownership registry. The constitutionality of the CTA is subject to litigation, and on March 21, 2025, FinCEN issued an interim final rule that significantly revised the definition of "reporting company" in its implementing regulations to mean only those entities that are formed under the law of a foreign country and that have registered to do business in any U.S. State or Tribal jurisdiction by the filing of a document with a secretary of state or similar office (formerly known as "foreign reporting companies"). FinCEN also exempts entities previously known as "domestic reporting companies" from BOI reporting requirements. Thus, through this interim final rule, all entities created in the United States — including those previously known as "domestic reporting companies" — and their beneficial owners are exempt from the requirement to report BOI to FinCEN. Foreign entities that meet the new definition of a "reporting company" and do not qualify for an exemption from the reporting requirements must report their BOI to FinCEN under new deadlines, detailed below. These foreign entities, however, will not be required to report any U.S. persons as beneficial owners, and U.S. persons will not be required to report BOI with respect to any such entity for which they are a beneficial owner.

***OFAC Regulation***

The U.S. Treasury Department's Office of Foreign Assets Control, or OFAC is responsible for administering U.S. economic sanctions which can prohibit certain transactions with designated foreign countries, nationals and others. OFAC-administered sanctions take on many different forms. For example, sanctions may include: (1) restrictions on trade with or investment in a sanctioned country, including prohibitions against direct or indirect imports from and exports to a sanctioned country and prohibitions on U.S. persons engaging in financial transactions relating to, making investments in, or providing investment-related advice or assistance to, a sanctioned country; and (2) blocking assets in which certain sanctioned foreign governments, entities or individuals have an interest, by prohibiting transfers of property subject to U.S. jurisdiction, including property in the possession or control of U.S. persons. OFAC also maintains a list of designated persons, groups or entities that are the target of sanctions, including the "Specially Designated Nationals and Blocked Persons List." The assets of designated persons, groups or entities are blocked and U.S. persons are generally prohibited from dealing with any such persons. Moreover, blocked assets, for example property and bank deposits, cannot be paid out, withdrawn, set off or transferred in any manner without a license from OFAC. If we find a name on any transaction, account or wire transfer associated with a sanctioned person, we must freeze or block such account or transaction, file a blocked property report with OFAC and notify the appropriate authorities. Failure to comply with U.S. economic sanctions could have serious legal and regulatory consequences.

***The Volcker Rule***

In December 2013, federal regulators adopted final regulations regarding the Volcker Rule established in the Dodd-Frank Act. The Volcker Rule generally prohibits banks and their affiliates from engaging in proprietary trading and investing in and sponsoring certain unregistered investment companies generally covering hedge funds and private equity funds, subject to certain exemptions. Banking entities had until July 21, 2017 to conform their activities to the requirements of the rule. Since S&T generally does not engage in the activities prohibited by the Volcker Rule, the effectiveness of the rule has not had a material effect on S&T Bank or its affiliates.

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

**Data Privacy and Cybersecurity**

We are subject to a variety of regulatory requirements regarding data privacy, data security and cybersecurity. For example, current federal laws, rules, regulations and standards, including the Gramm-Leach-Bliley Act, or GLBA, require financial institutions to, among other things, periodically disclose their privacy policies and practices relating to sharing personal information and enable retail customers to opt out of our ability to share such personal information with unaffiliated third parties under certain circumstances. Such laws and regulations also require financial institutions to implement a comprehensive cybersecurity program that includes administrative, technical and physical safeguards to ensure the security and confidentiality of customer records and information. Other federal and state laws and regulations impact our ability to share certain information with affiliates and non-affiliates for marketing and/or non-marketing purposes, or to contact customers with marketing offers. Federal law also makes it a criminal offense, except in limited circumstances, to obtain or attempt to obtain customer information of a financial nature by fraudulent or deceptive means. S&T Bank is also subject to rules and regulations issued by the Federal Trade Commission which regulates unfair or deceptive acts or practices, including with respect to data privacy and cybersecurity. Additionally, like other lenders, S&T Bank uses credit bureau data in its underwriting activities. Use of such data is regulated under the Fair Credit Reporting Act which also regulates reporting information to credit bureaus, prescreening individuals for credit offers, sharing of information between affiliates, and using affiliate data for marketing purposes. Similar state laws may impose additional requirements on us and our subsidiaries. The federal government also is considering, and may pass, additional data privacy and cybersecurity legislation, to which we may become subject if passed.

Federal and state regulators of financial institutions have issued guidance regarding cybersecurity, addressing the scope of controls that financial institutions should implement and maintain and business continuity planning and recovery processes that should be in place. Additionally, the FDIC, OCC and Federal Reserve issued a final rule that became effective in May 2022, requiring banking organizations that experience a computer-security incident to notify certain entities and its federal regulator as soon as possible and no later than 36 hours after the bank determines a computer-security incident has occurred. This rule also requires banking organizations to notify their customers of a computer-security incident that has caused, or is reasonably likely to cause, a material service disruption or degradation for four or more hours. In March of 2022, the Cyber Incident Reporting for Critical Infrastructure Act, or CIRCIA, was enacted and once final rules are adopted, will require certain covered entities to report a covered cyber incident to the U.S. Department of Homeland Security's Cybersecurity & Infrastructure Security Agency, or CISA, within 72 hours after a covered entity reasonably believes an incident has occurred. Separate reporting to CISA will also be required within 24 hours if a ransom payment is made as a result of a ransomware attack. Furthermore, in September 2023, the SEC's Cybersecurity Risk Management, Strategy, Governance and Incident Disclosure rules went into effect requiring, among other disclosure obligations, companies to publicly disclose the occurrence of a material cybersecurity incident, including the material aspects of the nature, scope, timing and impact of the incident on the company's financial condition and results of operations and brand beginning with any material cybersecurity incidents that occur on or after December 18, 2023.

State regulators have also been increasingly active in implementing privacy and cybersecurity standards and regulations, including data access requests and breach notification requirements. We actively monitor developments regarding regulatory expectations and federal and state requirements with respect to cybersecurity, data access requests and data breach notifications.

**Other Legislative and Regulatory Changes**

Various legislative and regulatory proposals are being considered by the executive branch of the federal government, Congress and various state governments, including Pennsylvania, that would result in substantial changes in banking, the regulation of banks, thrifts and other financial institutions, compensation, the regulation of financial markets and their participants, financial instruments and securities and the regulators and taxation of these entities.

Throughout 2025, Congress and the federal bank regulators expanded the scope of permissible digital asset activities for banks. The Government Enabling New Innovative Unstoppable Systems Act, or GENIUS Act, enacted in July 2025 as a significant piece of legislation aimed at establishing a comprehensive regulatory framework for stablecoins and digital assets in the U.S. The GENIUS Act provides clarity on the treatment of digital currencies, including the framework for stablecoin issuances by bank and non-banking entities, custody, reserves and payments systems and adopts a supervisory framework for stablecoin issuers. Under the GENIUS Act, banks are allowed to engage in stablecoin issuances and hold related reserves, provided they comply with established AML, KYC and capital adequacy standards.

In addition, the FDIC and Federal Reserve issued revised guidance regarding their engagement in crypto-related activities. This guidance rescinds prior guidance which previously required banks to submit prior notifications to the FDIC before engaging in such activities. Under the new framework, banks may engage in permissible crypto-related services, including custody and stablecoin reserve management, without needing to receive prior FDIC approval. However, banks are still required to manage risks effectively, including market, liquidity, operational and cybersecurity risks, and to comply with all AML/CFT and consumer protection requirements.

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

While we are not yet directly involved in stablecoin issuance or similar digital asset services, we continue to monitor developments under the GENIUS Act and FDIC policy, particularly as they evolve in the areas of digital asset custody, payments systems and associated regulatory requirements. The FDIC's recent approach signals that smaller banks have greater flexibility to explore these opportunities, provided they adhere to compliance standards designed to protect customers and ensure safety and soundness.

**Competition**

S&T Bank competes with other local, regional and national financial services providers, such as other financial holding companies, commercial banks, credit unions, finance companies, brokerage and insurance firms and financial technology companies, including competitors that provide their products and services online and through mobile devices. Some of our competitors are not subject to the same level of regulation and oversight that is required of banks and bank holding companies and are thus able to operate under lower cost structures. Our wealth management business competes with trust companies, mutual fund companies, investment advisory firms, law firms, brokerage firms and other financial services companies.

Changes in bank regulation, such as changes in the products and services banks can offer and permitted involvement in non-banking activities by bank holding companies, as well as bank mergers and acquisitions, can affect our ability to compete with other financial services providers. Our ability to do so will depend upon how successfully we can respond to the evolving competitive, regulatory, technological and demographic developments affecting our operations.

Our customers are primarily in Pennsylvania and the contiguous states of Ohio, New York, West Virginia, New Jersey, Delaware and Maryland. The majority of our commercial and consumer loans are made to businesses and individuals in these states resulting in geographic concentration. Our market area has a high density of financial institutions, some of which are significantly larger institutions with greater financial resources than us, and many of which are our competitors to varying degrees. Our competition for loans comes principally from commercial banks, mortgage banking companies, credit unions, online lenders and other financial service companies. Our most direct competition for deposits has historically come from commercial banks and credit unions. We face additional competition for deposits from non-depository competitors such as the mutual fund industry, securities and brokerage firms, insurance companies and financial technology companies. Since larger competitors have advantages in attracting business from larger corporations, we do not generally attempt to compete for that business. Instead, we concentrate our efforts on attracting the business of individuals, and small and medium-sized businesses. We consider our competitive advantages to be customer service and responsiveness to customer needs, the convenience of banking offices and hours, access to electronic banking services and the availability and pricing of our customized banking solutions. We emphasize personalized banking and the advantage of local decision-making in our banking business.

The financial services industry is likely to become more competitive as further technological advances enable more companies to provide financial services on a more efficient and convenient basis. Technological innovations have lowered traditional barriers to entry and enabled many companies to compete in financial services markets. Many customers now expect a choice of banking options for the delivery of services, including traditional banking offices, telephone, internet, mobile, ATMs, self-service branches, in-store branches and/or digital and technology-based solutions. These delivery channels are offered by traditional banks and savings associations, credit unions, brokerage firms, asset management groups, financial technology companies, finance and insurance companies, internet-based companies and mortgage banking firms.

**Item 1A. RISK FACTORS**

Investments in our common stock involve risk. The following discussion highlights the risks that we believe are material to S&T, potentially impacting our business, results of operations, financial condition and cash flows. However, other factors not discussed below or elsewhere in this Annual Report on Form 10-K could adversely affect our businesses, results of operations and financial condition. Therefore, the risk factors below do not necessarily include all risks that we may face.

***Risks Related to Credit***

**Our ability to assess the credit-worthiness of our customers may diminish which may adversely affect our results of operations.**

We incur credit risk by virtue of making loans and extending loan commitments and letters of credit. Credit risk is one of our most significant risks. We manage our exposure to credit risk through the use of consistent underwriting standards that emphasize "in-market" lending while avoiding excessive industry and other concentrations. Our credit administration function employs risk management techniques to ensure that loans adhere to corporate policy and problem loans are promptly identified. There can be no assurance that such measures will be effective in avoiding undue credit risk. If the models and approaches that we use to select, manage and underwrite our consumer and commercial loan products change and our underwriting standards do not reflect or capture the rapid changes in the economy, we may have higher credit losses.

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

**The value of the collateral used to secure our loans may not be sufficient to compensate for the amount of unpaid loans and we may be unsuccessful in recovering the remaining balances from our customers.**

Decreases in collateral values underlying our loans, particularly with respect to our commercial real estate, or CRE, and commercial and industrial, or C&I, could adversely affect our customers' ability to repay these loans which in turn could impact our profitability. Repayment of our commercial loans is often dependent on the cash flow of the borrower which may become unpredictable. If the value of the assets, such as real estate or business assets, serving as collateral for the loan portfolio were to decline materially, a significant part of the loan portfolio could become under-collateralized. If the loans that are secured by real estate become troubled when real estate market conditions are declining or have declined, in the event of foreclosure, we may not be able to realize the amount of collateral that was anticipated at the time of originating the loan. The underlying business assets that serve as collateral for C&I loans may be specific and unique to the borrowers industry; therefore, when the borrower encounters financial difficulties, the business assets may not have sufficient value. This could result in higher charge-offs which could have a material adverse effect on our operating results and financial condition.

**Changes to our provision for credit losses or ACL could significantly impact our operating results and financial condition.**

Like other lenders, we face the risk that our customers will not repay their loans. We reserve for losses in our loan portfolio based on our assessment of expected credit losses. Management determines the amount of allowance for credit losses, or ACL, through undergoing a periodic review of the loan portfolio, where it considers historical losses, forward-looking information including management's assessment of the macroeconomic conditions, including the national unemployment forecast produced by the Federal Reserve and qualitative factors around current conditions including changes in lending policies and practices, economic conditions, changes in the loan portfolio, changes in lending management, results of internal loan reviews, asset quality trends, collateral values, concentrations of credit risk and other external factors. This process, which is critical to our financial results and condition, requires complex judgment including our assessment of economic conditions which are difficult to predict. The amount of future losses is difficult to predict because it is susceptible to changes in economic, operating and other conditions, including changes in interest rates which may be beyond our control. Although we have policies and procedures in place to determine future losses, due to the subjective nature of this area, there can be no assurance that our management has accurately assessed the level of allowance reflected in our consolidated financial statements. We may underestimate our expected credit losses and fail to hold an ACL sufficient to account for these losses or we may overestimate expected credit losses and maintain an ACL in excess of what is required. Incorrect assumptions could lead to material underestimates or overestimates of expected losses and an inadequate or excessive ACL. As our assessment of expected losses changes, we may need to increase or decrease our ACL which could significantly impact our operating results and financial condition.

**Our loan portfolio is concentrated within our market area, and our lack of geographic diversification increases our risk profile.**

The regional economic conditions within our market area affect the demand for our products and services as well as the ability of our customers to repay their loans and the value of the collateral securing these loans. A significant decline in the regional economy caused by inflation, recession, unemployment or other factors could negatively affect our customers, the quality of our loan portfolio and the demand for our products and services. Any sustained period of increased payment delinquencies, foreclosures or losses caused by adverse market or economic conditions in our market area could adversely affect the value of our assets, revenues, results of operations and financial condition. Moreover, we cannot give any assurance that we will benefit from any market growth or favorable economic conditions in our primary market area.

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

**Our loan portfolio has a significant concentration of commercial loans that have a higher risk of loss.**

The majority of our loans are to commercial borrowers including C&I, Commercial Real Estate, or CRE, and construction loans. The commercial loan portfolio typically involves a higher degree of credit risk than other types of loans. For the C&I segment this is due to the customer's repayment ability being based upon the success of its business operations, the susceptibility of the customer's business to changing economic conditions, the dependence of our customer on maintaining sufficient cash flow to make payments on the loan and our reliance on the underlying collateral which is usually only the business assets that may not have sufficient value when the borrower encounters financial difficulties. For the CRE segment higher risk is due to higher loan principal amounts, where the repayment of these loans is generally dependent, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service. Because payments on loans secured by CRE often depend upon the successful operation and management of the properties, repayment of these loans may be affected by factors outside the borrower's control, including adverse conditions in the real estate market or the economy. Additionally, we have a number of significant credit exposures to commercial borrowers, and while the majority of these borrowers have numerous projects that make up the total aggregate exposure, if one or more of these borrowers default or have financial difficulties, we could experience higher credit losses which could adversely impact our financial condition and results of operations. Further, an individual commercial loan balance is typically larger than other loans in our portfolio, creating the potential for larger credit losses on an individual loan. The deterioration of one or a few of these loans could have a material adverse effect on our financial condition and results of operations.

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

***Risks Related to General Economic Conditions***

**General economic conditions may adversely impact our business, financial condition, results of operations or cash flows.**

Various aspects of our business could be impacted by general macroeconomic conditions including, among others, inflation, interest rates, rising or elevated unemployment, declines in GDP, consumer spending, property values, supply chain complications and economic uncertainty. These conditions generally have a negative impact on businesses, financial markets and consumers which may impact the underlying credit quality of our customers. The following could increase the risk of our customers defaulting or becoming delinquent in their obligations to us which could increase credit losses and adversely affect our credit portfolios and provision for credit losses: (i) increased cost of borrowings, (ii) additional borrowings and increased leverage, (iii) drawdown from savings due to business disruption, (iv) financial difficulties, or (v) business losses, particularly for borrowers in our C&I or CRE portfolio. Furthermore, the United States has recently enacted significant new tariffs and may enact additional tariffs. There continues to be significant uncertainty and concern about the future relationship between the U.S. and other countries, including with respect to trade policies, treaties, government regulations, sanctions, tariffs, and application thereof, since the imposition of tariffs that began in April 2025. We are continuing to evaluate the impact of tariffs and trade policies on our business and our customers; however, we cannot provide any assurance about the ultimate outcome or impact of these measures. Additional changes to United States tariffs and/or other trade policies, retaliatory measures and the effect of cost increases and continued uncertainty may have a negative effect on the underlying credit quality of our customers, and increase the risk of our customers defaulting or becoming delinquent in their obligations to us. If the macroeconomic environment worsens, our credit portfolio and ACL could be adversely impacted. These unfavorable economic conditions could also impact the demand for loans and other products and services offered by us, the level of customer deposits, the value of our investment securities, loans held for sale or other assets secured by residential or commercial real estate or the level of net interest income or net interest margin. Any of these developments could adversely impact our business, financial condition, results of operations or cash flows. Additionally, changes to the size, structure, and operation of the federal government, including the workforce reduction, elimination or curtailment of federal agencies, delivery of government services and distribution of federal program funds and benefits may cause economic disruption that could adversely impact our customers and our business, results of operations and financial condition.

**We may not accurately predict the nature and timing of the policies of the Federal Reserve and other governmental agencies and their impact on interest rates and financial markets which could negatively impact our financial condition and results of operations.**

The monetary policies of the Federal Reserve have a significant impact on interest rates, the value of financial instruments and other assets and liabilities, and overall financial market performance. These policies have a significant impact on the activities and results of operations of banks and bank holding companies such as S&T. An important function of the Federal Reserve is to monitor the national supply of bank credit and set certain interest rates. The actions of the Federal Reserve influence the rates of interest that we charge on loans and that we pay on borrowings and interest-bearing deposits. In addition, monetary policy actions by governmental authorities in the European Union or other countries could have an impact on global interest rates which could affect rates in the U.S. We may not accurately predict the nature or timing of future changes in monetary policies and interest rates or the precise effects that they may have on our activities and financial results which could negatively impact our financial condition and results of operations.

**Financial challenges at other banking institutions; adverse developments affecting the financial services industry; concerns regarding the soundness of financial institutions; and further disruption to the economy and the U.S. banking system may adversely affect our business, results of operations, liquidity and stock price**

Several bank receiverships in 2023 caused a state of volatility in the financial services industry and uncertainty with respect to liquidity and the health of the U.S. banking system. Although we were not directly affected by these bank receiverships, this news caused fear among depositors which caused them to withdraw or attempt to withdraw their funds from these and other financial institutions. Uncertainty may be compounded by the reach and depth of media attention, including social media, and its ability to disseminate concerns or rumors about any events of these kinds or other similar risks, and have in the past and may in the future lead to market-wide liquidity problems. Additionally, the stock prices of many financial institutions dropped and became volatile. While the FDIC resolution of these banks was done in a manner that protected depositors, there remains concern over the U.S. banking system as a result of continued economic volatility. Furthermore, financial services institutions are interrelated as a result of trading, clearing, counterparty or other relationships which may expose us to credit risk and losses in the event of a default by a counterparty or client. As a result of these events, we face the potential for brand risk, deposit outflows and increased credit risk, which individually or in the aggregate, could have a material adverse effect on our business, financial condition and results of operations and liquidity.

Furthermore, if such levels of financial market and economic disruption and volatility continue, if actual events or concerns or rumors involving limited liquidity, defaults, or other adverse developments, or if other banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, our ability to access our existing cash, cash equivalents and investments may be threatened due to market-wide liquidity problems. While we maintain liquidity primarily through customer deposits and through access to other short-term funding sources, including advances from the Federal Home Loan Bank, or FHLB, our efforts to monitor and manage liquidity risk may not be successful or sufficient to deal with dramatic or unanticipated increases or reductions in our liquidity, particularly in light of the impact of increased interest rates on the market value of investment securities. This situation could have a material adverse impact on our results of operations and financial condition.

Although the FDIC made deposit insurance assessment accommodations December 2025, periods of stress in the banking industry often result in increased deposit insurance assessments when banks fail, increased scrutiny by federal and state regulators, including State attorneys general, as well as potential investigations or litigation relating to liquidity management, deposit practices, disclosures or risk management. Such actions, regardless of merit, could have material adverse effects on our business, results of operations, financial condition and growth prospects.

**Geopolitical tensions and conflicts between nations have created significant economic and financial disruptions and uncertainties which could adversely affect our business, financial condition and results of operations.**

The continuing conflict resulting from Russia's military attack on Ukraine in February 2022 and other armed conflicts such as that involving Hamas and Israel beginning in October 2023 may cause detrimental effects on the global economy. This conflict, as well as further escalation of tensions between Israel and various countries in the Middle East, North Africa and rising tensions between United States and Venezuela, may cause additional detrimental effects on the global economy, including financial and capital markets which could adversely impact our results of operations.

Although the extent and duration of these military conflicts and any future escalation of such hostilities, market disruptions and volatility and the result of any diplomatic negotiations remains uncertain, these consequences, including those we cannot yet predict, may cause our business, financial condition, results of operations and the price of our common stock to be adversely affected.

***Risks Related to Our Operations***

**Failure to keep pace with technological changes and successfully implement current or future information technology system enhancements could have a material adverse effect on our results of operations and financial condition.**

The financial services industry is constantly undergoing rapid technological change with frequent introductions of new technology-driven products and services, including the use of artificial intelligence and digital assets. The effective use of technology increases efficiency and enables financial institutions to better service customers and reduce costs. Our future success depends, in part, upon our ability to address the needs of our customers by using technology to provide products and services that will satisfy their demands, as well as create additional efficiency within our operations. We continue to invest in information technology systems in order to provide functionality to improve our operating efficiency and to streamline our client experience. We may not be able to effectively implement new technology-driven products, enhancements and services quickly or be successful in marketing these products and services to our customers. Failure to successfully keep pace with technological change affecting the financial services industry, including but not limited to changes affecting our information systems resulting in incidents, attacks or breaches in cybersecurity; or utilize system enhancements that are implemented in the future, could have a material adverse impact on our business, financial condition and results of operations. As such, we cannot guarantee anticipated long-term benefits from these system enhancements and operational initiatives.

**A cyber attack, information or security breach, or a failure of ours or of a third-party's infrastructure, computer and data management systems could adversely affect our ability to conduct our business or manage our exposure to risk, result in the disclosure or misuse of confidential or proprietary information, increase our costs to maintain and update our operational and security systems and infrastructure, and adversely impact our results of operations, liquidity and financial condition, as well as cause diminished customer, employee or investor confidence.**

Our business is highly dependent on the security and efficacy of our infrastructure, computer and data management systems, as well as those of third parties with whom we interact. Cybersecurity risks for financial institutions have significantly increased in recent years in part because of the proliferation of new technologies, the use of the Internet and telecommunications technologies to conduct financial transactions, and the increased sophistication and activities of organized crime, hackers, terrorists and other external parties, including foreign state actors. Our operations rely on the secure processing, transmission, storage and retrieval of confidential, proprietary and other information in our computer and data management systems and networks, and in the computer and data management systems and networks of third parties. We rely on digital technologies, computer, database and email systems, software and networks to conduct our operations. In addition, to access our network and products and services, our customers and third parties may use personal mobile devices or computing devices that are outside of our network environment. We have taken measures to implement backup systems and other safeguards to support our operations, but our ability to conduct business may be adversely affected by any significant disruptions to us or to third parties with whom we interact. We further issue debit cards which are susceptible to compromise at the point of sale via the physical terminal through which transactions are processed and by other means of hacking. The security and integrity of these transactions are dependent upon the retailers' vigilance and willingness to invest in technology and upgrades. Issuing debit cards to our clients exposes us to potential losses, which in the event of a data breach at one or more major retailers, may adversely affect our business, financial condition and results of operations.

Financial services institutions, and third parties whom they conduct business with, have been subject to, and are likely to continue to be the target of, cyber attacks, including computer viruses, malicious or destructive code, phishing attacks, denial of service, adversarial artificial intelligence or other security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of confidential, proprietary and other information of the institution, its employees or customers or of third parties, or otherwise materially disrupt network access or business operations. For example, denial of service attacks have been launched against a number of large financial institutions and several large retailers have disclosed substantial cybersecurity breaches affecting debit accounts of their customers. We have experienced cybersecurity incidents in the past, such as vendor malware attacks, phishing and other social engineering schemes designed to gain access to confidential information from our employees, customers or vendors and, although not material, we anticipate that we could experience further incidents of that nature as well as other types of attempts or incidents. Specifically, the rapid evolution of artificial intelligence, generative artificial intelligence and quantum computing has enabled malicious actors to develop more advanced social engineering attacks. Furthermore, the potential development of quantum computing capabilities poses future risks to existing cryptographic standards which could jeopardize the integrity of our secure data transmissions. There can be no assurance that we will not suffer material losses or other material consequences relating to technology failure, cyber incidents or other information or security breaches.

In addition to external threats, insider threats also present a risk to us. Insiders, having legitimate access to our systems and the information contained in them, have the opportunity to make inappropriate use of the systems and information, or as a result of human error, misconduct or malfeasance, expose us to risk. We have policies, procedures and controls in place designed to prevent or limit this risk, but we cannot guarantee that these policies, procedures and controls fully mitigate this risk.

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

Additionally, a number of our employees have the ability to work from remote locations, increasing the number of surfaces that require protection and the overall risks and exposures to cyber threats.

We have taken and continue to take measures to design, implement and reassess our controls, backup systems and other safeguards to support our operations, but no matter how well designed or implemented, we may not be able to anticipate and prevent all potential types of security incidents and breaches, and we may not be able to implement effective preventive measures against such security breaches in a timely manner. As cyber threats continue to evolve, we may also be required to expend significant additional resources to continue to modify or enhance our systems or to investigate and remediate vulnerabilities. System enhancements and updates have further potential to create risks associated with implementing and integrating new systems. Due to the complexity and interconnectedness of information technology systems, the process of enhancing our systems can itself create a risk of systems disruptions and security issues. Any of these matters could result in failure, circumvention of our security systems or significant disruptions to us or third parties with whom we interact, misappropriation or destruction of our confidential information and/or that of our customers, or damage to our customers' and/or third parties' computers or systems, loss of our customers and business opportunities, and could result in a violation of applicable privacy laws and other laws, litigation exposure, regulatory fines, penalties or intervention, loss of confidence in our security measures, negative public opinion, reimbursement or other compensatory costs and additional compliance costs. In addition, any of the matters described above could have a material adverse impact on our results of business operations and financial condition.

Any of the foregoing risks may cause us to experience a cybersecurity incident, attack or breach. A successful security breach of our information or security systems or those of third parties whom we interact with could incur substantial costs or other negative consequences which cause us to suffer material losses. Examples of such material losses include, but are not limited to: (1) remediation costs, such as liability for stolen assets or information, repairs of system damage and incentives to customers in an effort to maintain relationships after an attack; (2) violations of applicable privacy and other laws; (3) loss of confidence in its security measures; (4) increased cybersecurity protection costs, such as organizational changes, deploying additional personnel and protection technologies, training employees and engaging third party experts and consultants; (5) significant litigation exposure; (6) negative public opinion; (7) financial loss; and (8) damage to our competitiveness, stock price and long-term shareholder values. There can be no assurance we will not suffer material losses or other material consequences relating to technology failure, cyber incidents or other information or security breaches experienced by us or the third parties whom we interact with.

While we maintain a cyber insurance policy that is designed to cover a majority of loss resulting from cybersecurity breaches, there is no assurance such coverage or other protective measures we employ will be adequate to address all potential material adverse impacts as cybersecurity incidents increase in frequency and magnitude. Any breach of our system security could result in disruption of our operations, unauthorized access to confidential customer information, significant regulatory costs, litigation exposure and other possible damages, loss or liability. Such costs or losses could exceed the amount of available insurance coverage, if any, and would adversely affect our results of operations.

Moreover, we are subject to laws and regulations in the United States and other jurisdictions regarding privacy, data protection and data security and there continues to be heightened legislative and regulatory focus in this area. These laws and regulations are rapidly evolving and increasing in complexity and will require us to incur costs, some of which may be significant, to achieve and maintain compliance and could restrict our ability to provide certain products and services which could have an adverse effect on our business, financial condition and results of operations. Furthermore, as cybersecurity incidents increase in frequency and magnitude, we may be unable to obtain cybersecurity insurance in amounts and on terms we view as adequate for our operations.

For more information on how S&T manages cybersecurity risk, please refer to the discussion provided below under "Part I, Item 1C. Cybersecurity."

**Fraudulent activity associated with our products and services could adversely affect our results of operations, financial condition and stock price, negatively impact our brand and result in regulatory intervention or sanctions.**

As a financial institution we are exposed to operational risk in the form of fraudulent activity that may be committed by customers, other third parties or employees, targeting us and our customers. The risk of fraud continues to increase for the financial services industry. Fraudulent activity has escalated, become more sophisticated, and continues to evolve, as there are more options to access financial services. The sophistication of generative artificial intelligence enables the automation and refinement of fraudulent schemes, including the creation of deceptive financial records, synthetic media and highly persuasive social engineering attacks. While we believe we have operational risk controls in place to prevent or detect fraud or to mitigate the impact of any fraud, we cannot provide assurance that we can prevent or detect fraud or that we will not experience future fraud losses or incur costs or other damage related to such fraud, at levels that adversely affect our results of operations, financial condition or stock price. Furthermore, fraudulent activity could negatively impact our brand which could also adversely affect our results of operations, financial condition or stock price. Fraudulent activity could also lead to regulatory intervention or regulatory sanctions.

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

**We rely on certain critical third-party providers for a number of services that are important to our business. An interruption or cessation of an important service by any critical third-party provider could have a material adverse effect on our business.**

We are dependent for the majority of our technology, including our core operating system, on certain critical third-party providers. If these companies were to discontinue providing services to us, we may experience significant disruption to our business. In addition, each of these third parties faces the risk of cyber attack, information breach or loss or technology failure. If any of our critical third-party service providers experience such difficulties, or if there is any other disruption in our relationships with them, we may be required to find alternative sources of such services. We are dependent on these critical third-party providers securing their information systems, over which we have limited control, and a breach of their information systems could adversely affect our ability to process transactions, service our clients or manage our exposure to risk and could result in the disclosure of sensitive, personal customer information which could have a material adverse impact on our business through damage to our brand, loss of business, remedial costs, additional regulatory scrutiny or exposure to civil litigation and possible financial liability. We also depend on third-party vendors and service providers for core systems and specialized tools that may incorporate artificial intelligence functionality. Our ability to manage artificial intelligence related risk is therefore partially dependent on the controls, governance and resilience of those third parties. If a vendor's artificial intelligence system fails, is inadequately governed, is subject to regulatory action or experiences a cyber incident or service disruption, we may be unable to continue certain operations, may incur remediation costs or may face contractual or regulatory consequences. Assurance cannot be provided that we could negotiate terms with alternative service sources that are as favorable or could obtain services with similar functionality as found in existing systems without the need to expend substantial resources, if at all, thereby resulting in a material adverse impact on our business and results of operations.

**Failure to continue to attract, develop and maintain a highly skilled workforce may have an adverse effect on our business.**

Our business requires that we attract, develop and maintain a highly skilled workforce. Competition for qualified employees and personnel in the banking industry is strong, and there are a limited number of qualified persons with knowledge of, and experience in, the banking industry where we conduct our business. Our ability to attract and retain skilled personnel cost effectively is subject to a variety of external factors, including the limited availability of qualified personnel in the workforce in the local markets in which we operate, unemployment levels within those markets, prevailing wage rates which have increased significantly, health and other insurance costs and changes in employment and labor laws. Furthermore, the complexities introduced into the labor market as a result of the transition to increased work-from-home arrangements have impacted the competitive landscape in our labor market. Based on current conditions in the labor market, we have experienced some difficulty in retaining and attracting personnel and there is no assurance that we will be able to continue to successfully do so.

***Risks Related to Our Business Strategy***

**Our strategy includes growth plans through organic growth and by means of acquisitions. Our financial condition and results of operations could be negatively affected if we fail to grow or fail to manage our growth effectively.**

We intend to continue pursuing a growth strategy through organic growth within our current footprint and through market expansion. We also actively evaluate acquisition opportunities as another source of growth. We cannot give assurance that we will be able to expand our existing market presence, or successfully enter new markets or that any such expansion will not adversely affect our results of operations. Failure to manage our growth effectively could have a material adverse effect on our business, future prospects, financial condition or results of operations and could adversely affect our ability to successfully implement our business strategy.

Our failure to find suitable acquisition candidates, or successfully bid against other competitors for acquisitions, could adversely affect our ability to fully implement our business strategy. If we are successful in acquiring other entities, the process of integrating such entities will divert significant management time and resources. We may not be able to integrate efficiently or operate profitably any entity we may acquire. We may experience disruption and incur unexpected expenses in integrating acquisitions. These failures could adversely impact our future prospects and results of operations.

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

**We are subject to competition from both banks and non-banking companies.**

The financial services industry is highly competitive, and we encounter strong competition for deposits, loans and other financial services in our market area, including online providers of these products and services. Our principal competitors include other local, regional and national financial services providers, such as other financial holding companies, commercial banks, financial technology companies, credit unions, finance companies and brokerage and insurance firms, including competitors that provide their products and services online. Many of our non-bank competitors are not subject to the same degree of regulation that we are and have advantages over us in providing certain services. Additionally, many of our competitors are significantly larger than we are and have greater access to capital and other resources. Failure to compete effectively for deposit, loan and other financial services customers in our markets could cause us to lose market share, slow our growth rate and have an adverse effect on our financial condition and results of operations.

In addition, transactions utilizing digital assets, including cryptocurrencies, stablecoins and other similar assets have increased over the past few years and continue to gain wider market acceptance. Certain characteristics of digital asset transactions, including their speed and anonymity are appealing to certain consumers notwithstanding the various risks posed by such transactions. In addition, certain cryptocurrency exchanges and other market participants may pay yield on digital asset holdings in the same manner as interest-bearing deposit accounts which may result in loss of deposits. Accordingly, digital asset service providers, who currently are not subject to the same extensive regulation as banking organizations and other financial institutions, have become potential competitors for our customers' banking business.

**We may be required to raise capital in the future, but that capital may not be available or may not be on acceptable terms when it is needed.**

We are required by federal regulatory authorities to maintain adequate capital levels to support operations. While we believe we currently have sufficient capital, if we cannot raise additional capital when needed, we may not be able to meet these requirements. In addition, our ability to further expand our operations through organic growth, which includes growth within our current footprint and growth through market expansion, may be adversely affected by any inability to raise necessary capital. Our ability to raise additional capital at any given time is dependent on capital market conditions at that time and on our financial performance and outlook.

***Risks Related to Interest Rates and Investments***

**Our net interest income could be negatively affected by interest rate changes which may adversely affect our financial condition and results of operations.**

Our results of operations are largely dependent on net interest income which is the difference between the interest and fees earned on interest-earning assets and the interest paid on interest-bearing liabilities. Therefore, any change in general market interest rates, including changes resulting from the Federal Reserve Board's policies, can have a significant effect on our net interest income and total income. There may be mismatches between the maturity and repricing of our assets and liabilities that could cause the net interest rate spread to compress, depending on the level and type of changes in the interest rate environment. Interest rates are highly sensitive to many factors that are beyond our control, including general economic conditions and the policies of various governmental agencies. In addition, some of our customers often have the ability to prepay loans or redeem deposits with either no penalties or penalties that are insufficient to compensate us for the lost income. A significant reduction in our net interest income will adversely affect our business and results of operations. If we are unable to manage interest rate risk effectively, our business, financial condition and results of operations could be materially impacted.

**Declines in the value of investment securities held by us could require write-downs which may adversely affect our financial condition and results of operations.**

In order to diversify earnings and enhance liquidity, we own debt instruments of the U.S. government, U.S. government agencies and U.S. municipalities. We may be required to record impairment charges on our debt securities if they suffer a decline in value due to the underlying credit of the issuer. Additionally, the value of these investments may fluctuate depending on the interest rate environment, general economic conditions and circumstances specific to the issuer. Volatile market conditions may detrimentally affect the value of these securities, such as through reduced valuations due to the perception of heightened credit or liquidity risks. Changes in the value of these instruments may result in a reduction to earnings and/or capital which may adversely affect our results of operations and financial condition.

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

***Risks Related to Regulatory Compliance and Legal Matters***

**We are subject to extensive governmental regulation and supervision.** 

As discussed above, under "Supervision and Regulation" in Item 1, we are subject to extensive state and federal regulation, supervision and legislation that govern nearly every aspect of our operations. The regulations are primarily intended to protect depositors, customers and the banking system as a whole, not shareholders. These regulations affect our lending practices, capital structure, investment practices, dividend policy and growth, among other things. Congress and federal regulatory agencies continually review banking laws, regulations and policies for possible changes. The Dodd-Frank Act, enacted in July 2010, instituted major changes to the banking and financial institutions regulatory regimes. Other changes to statutes, regulations or policies could affect us in substantial and unpredictable ways. Any regulatory changes could subject us to additional costs of regulatory compliance and of doing business, limit the types of financial services and products we may offer and/or increase the ability of non-banks to offer competing financial services and products, among other things, and could divert management's time from other business activities. Failure to comply with applicable laws, regulations, policies or supervisory guidance could lead to enforcement and other legal actions by federal or state authorities, including criminal or civil penalties, the loss of FDIC insurance, the revocation of a banking charter, other sanctions by regulatory agencies and/or damage to our brand. The ramifications and uncertainties of the level of government intervention and regulatory changes in the U.S. financial system could also adversely affect us. Failure to comply with the different or additional regulations could further adversely affect us.

**As we grow, the heightened expectations of regulatory agencies may expose us to additional regulatory risk and compliance costs.**

The regulations that we are subject to at this time are generally tailored to institutions with less than $10 billion in total consolidated assets. Should our total consolidated assets exceed the $10 billion threshold, we would be subject to additional regulatory requirements and supervisory oversight applicable to larger institutions. These requirements are intended to enhance risk management, governance and compliance frameworks and may include minimum standards for the design and implementation of the risk management framework and heightened requirements relating to enterprise risk management, board oversight, data governance, compliance management systems, internal audit, vendor oversight and cybersecurity controls, as well as increased regulatory scrutiny from our primary federal and state banking regulators. In addition, institutions with $10 billion or more in total consolidated assets are subject to supervision and examination by the CFPB with respect to applicable federal consumer financial laws and, beginning July 1 of the year following the calendar year in which the threshold is exceeded, to limitations on debit card interchange fees under the Durbin Amendment (subject to applicable exemptions). Deposit insurance assessment methodologies may also differ for institutions above this asset threshold.

The regulatory framework applicable to institutions above the $10 billion threshold is subject to ongoing rulemaking activity and supervisory calibration. Certain rules and standards applicable to larger institutions have been proposed, modified, delayed or challenged in court, and federal agencies have signaled an intent in some areas to streamline or tailor supervisory expectations. The timing, scope and ultimate impact of regulatory requirements applicable to institutions above the $10 billion threshold therefore remain subject to change. This evolving environment may create uncertainty in our compliance planning, capital allocation and operational investments and may require us to modify systems, policies and staffing as regulatory expectations develop. While we have taken steps to enhance our risk management and compliance infrastructure in anticipation of future growth, our existing enterprise risk framework and related systems may not be fully scalable to meet applicable expectations without significant additional investment. We may be required to incur substantial costs to upgrade systems, enhance internal controls and hire or train personnel with specialized expertise. Failure to effectively implement and maintain required controls could subject us to increased supervisory scrutiny, enforcement actions or civil penalties which could materially and adversely affect our business, financial condition, results of operations, reputation and ability to pursue strategic growth initiatives.

**Our controls and policies and procedures may fail or be circumvented which may result in a material adverse effect on our business, financial condition and results of operations.**

Management regularly reviews and updates our internal controls, disclosure controls and procedures and operating, risk management and corporate governance policies and procedures. Any system of controls, policies and procedures, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Furthermore, our risk management framework is subject to inherent limitations and risks may exist, or develop in the future, that we have not identified or anticipated. Any failure or circumvention of internal controls, disclosure controls and procedures, or operating, risk management and corporate governance policies and procedures, whether as a result of human error, misconduct or malfeasance, or failure to comply with regulations related to controls and policies and procedures could have a material adverse effect on our business, results of operations and financial condition.

**<u>[**Table of Contents**](#ia7d84a7456464799a5bd4ecb9ee914c6_7)</u>**

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

Furthermore, we may in the future discover areas of our internal controls, disclosure controls and procedures, or operating, risk management and corporate governance policies and procedures that need improvement. Failure to maintain effective controls or to timely implement any necessary improvement of our internal and disclosure controls, or operating, risk management and corporate governance policies and procedures, could, among other things, result in losses from errors, harm our brand, or cause investors to lose confidence in our reported financial information, all of which could have a material adverse effect on our results of operations and financial condition.

**Negative public opinion could damage our brand and adversely impact our results of operations and liquidity.**

Brand impacts to strategic risk, including the risk to our business, earnings, liquidity and capital from negative public opinion, is inherent in our operations. Negative public opinion could result from our actual or alleged conduct in a variety of areas, including legal and regulatory compliance, lending practices, corporate governance, cybersecurity incident or breach, failures by third parties whom we interact with, litigation, ethical issues or inadequate protection of customer information. Financial companies are highly vulnerable to brand damage when they are found to have harmed customers, particularly retail customers, through conduct that is illegal or viewed as unfair, deceptive, manipulative or otherwise wrongful. We are dependent on third-party providers for a number of services that are important to our business. Refer to the risk factor titled, "We rely on certain critical third-party providers for a number of services that are important to our business. An interruption or cessation of an important service by any third-party provider could have a material adverse effect on our business." for additional information. A failure by any of these third-party service providers could cause a disruption in our operations which could result in negative public opinion about us or damage to our brand. We expend significant resources to comply with regulatory requirements, and the failure to comply with such regulations could result in brand harm or significant legal or remedial costs. Damage to our brand could adversely affect our ability to retain and attract new customers and employees, expose us to litigation and regulatory action and adversely impact our results of operations and liquidity.

**Our ability to pay dividends on our common stock may be limited.**

Holders of our common stock will be entitled to receive only such dividends as our Board of Directors may declare out of funds legally available for such payments. The payment of common stock dividends by S&T is subject to certain requirements and limitations of Pennsylvania law. Although we have historically declared cash dividends on our common stock, we are not required to do so and our Board of Directors could reduce, suspend or eliminate our dividend at any time. Substantial portions of our revenue consist of dividend payments we receive from S&T Bank. The payment of common dividends by S&T Bank is subject to certain requirements and limitations under federal and state laws and regulations that limit the amount of dividends it can pay to S&T. In addition, both S&T and S&T Bank are subject to various general regulatory policies relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. Any decrease to or elimination of the dividends on our common stock could adversely affect the market price of our common stock.

**Our business could be negatively impacted by complex, evolving, and conflicting environmental, social and governance, or ESG, regulations and expectations, including climate change and related legislative and regulatory initiatives.**

Certain federal actions have created a complex environment with respect to ESG. Navigating the varying expectations of policy makers and other stakeholders may expose us to negative publicity, shareholder or other stakeholder engagement or potential enforcement or investigation by regulatory authorities, each of which could have an adverse impact on our business.

Although federal bank regulators have rescinded some prior ESG guidance and policies, new guidance and policies may be implemented in the future. Failure to adapt to or comply with regulatory requirements or investor or stakeholder expectations and standards with respect to ESG matters or failure to successfully manage varied stakeholder expectations could have a material adverse impact on our future results of operations, financial condition, cash flows, ability to do business with certain third parties and our stock price.

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

***Risks Related to Liquidity***

**We rely on a stable core deposit base as our primary source of liquidity.**

We are dependent for our funding on a stable base of core deposits. Our ability to maintain a stable core deposit base is a function of our financial performance, our brand and the security provided by FDIC insurance, which combined, gives customers confidence in us. If any of these considerations deteriorates, the stability of our core deposits could be harmed. Customers are also focused on the amount of deposit account balances that we hold in excess of FDIC insurance limits. As a result, they may decide to withdraw deposits in excess of these limits. In addition, deposit levels may be affected by factors such as general interest rate levels, rates paid by competitors, returns available to customers on alternative investments and general economic conditions. Accordingly, we may be required from time to time to rely on other sources of liquidity to meet withdrawal demands or otherwise fund operations. Additional funding sources accessible to S&T include borrowing availability through the Federal Reserve Borrower-in-Custody Program, the FHLB, federal funds lines with other financial institutions and brokered deposits.

**Our ability to meet contingency funding needs, in the event of a crisis that causes a disruption to our core deposit base, is dependent on access to wholesale markets, including funds provided by the FHLB of Pittsburgh, Federal Reserve Borrower-in-Custody Program and other short-term funding sources, including brokered deposits.**

We own stock in the FHLB, in order to qualify for membership in the FHLB system which enables us to borrow on our line of credit that is secured by a blanket lien on a significant portion of our loan portfolio. Changes or disruptions to the FHLB or the FHLB system in general may materially impact our ability to meet short- and long-term liquidity needs or meet growth plans. Additionally, we cannot be assured that the FHLB will be able to provide funding to us when needed, nor can we be certain that the FHLB will provide funds specifically to us, should our financial condition and/or our regulators prevent access to our line of credit. We have other funding sources that can be used such as the Federal Reserve Borrower-in-Custody Program and brokered deposits. The inability to access this source of funds could have a materially adverse effect on our ability to meet our customer's needs. Our financial flexibility could be severely constrained if we were unable to maintain our access to funding or if adequate financing is not available at acceptable interest rates.

***Risks Related to Owning Our Stock***

**The market price of our common stock may fluctuate significantly in response to a number of factors.**

Our quarterly and annual operating results have varied significantly in the past and could vary significantly in the future which makes it difficult for us to predict our future operating results. Our operating results may fluctuate due to a variety of factors, many of which are outside of our control, including the changing U.S. economic environment and changes in the commercial and residential real estate market, any of which may cause our stock price to fluctuate. If our operating results fall below the expectations of investors or securities analysts, the price of our common stock could decline substantially. Additionally, our stock price can fluctuate significantly in response to a variety of factors including, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• volatility of stock market prices and volumes in general;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in market valuations of similar companies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the nature and composition of our ownership base;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• investor views on the attractiveness of a given sector in the market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the flow of capital among market sectors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the conditions of credit markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in accounting policies or procedures as required by the Financial Accounting Standards Board, or FASB, or other regulatory agencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• legislative and regulatory actions, including the impact of the Dodd-Frank Act and related regulations, that may subject us to additional regulatory oversight which may result in increased compliance costs and/or require us to change our business model;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• government intervention in the U.S. financial system and the effects of and changes in trade and monetary and fiscal policies and laws, including the interest rate policies of the Federal Reserve;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• additions or departures of key members of management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in our quarterly or annual operating results; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in analysts' estimates of our financial performance.

***General Risk Factors***

**We may be a defendant from time to time in a variety of litigation and other actions which could have a material adverse effect on our financial condition and results of operations.**

From time to time, customers and others make claims and take legal action pertaining to the performance of our responsibilities. Whether customer claims and legal action related to the performance of our responsibilities are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to us, they may result in significant expenses, attention from management and financial liability. Any financial liability or brand damage could have a material adverse effect on our business which in turn could have a material adverse effect on our financial condition and results of operations.

**Item 1B. UNRESOLVED STAFF COMMENTS**

There are no unresolved SEC staff comments.

**Item 1C. CYBERSECURITY**

**Risk Management and Strategy**

S&T's Information Security Program provides policies, procedures, controls and technical measures to assess, identify and manage material cybersecurity risks. The Information Security Program is a part of S&T's overall Enterprise Risk Management, or ERM Program. The Information Security Program is designed to achieve the following objectives:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• protecting data through the use of automated and manual processes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• periodically assessing and updating the program to address an evolving threat environment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintaining a team of IT security professionals that continually monitor, detect, analyze, investigate and report cybersecurity threats; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ensuring business continuity and disaster recovery.

We based and tailored our framework on the National Institute of Standards and Technology, or NIST, Cybersecurity Framework and the Center for Internet Security, or CIS, Critical Security Controls.

The S&T Information Security Program utilizes a defense in depth strategy that leverages multiple security measures to protect the bank's assets. We encrypt and leverage data loss prevention technology for sensitive data and use advanced transport layer security encryption for our applications. S&T employees are required to undergo annual information security awareness training which includes information regarding evolving threats such as phishing, malware and social engineering testing.

S&T performs periodic risk assessments that seek to identify both technical and physical risks to information systems. The assessments incorporate cybersecurity-related principles from the Federal Financial Institutions Examination Council, or FFIEC, Information Technology Examination Handbook, regulatory guidance and concepts from other industry standards, including the NIST Cybersecurity Framework. An assessment typically includes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identifying reasonably foreseeable internal and external threats that could result in a cybersecurity incident;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assessing the likelihood and potential impact of those threats; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• assessing the sufficiency of policies, procedures, practices and technical measures in place to manage risks.

In addition to periodic risk assessments, S&T evaluates changes to IT systems or physical systems for any information security impacts. S&T utilizes staff and independent third parties to conduct annual penetration testing and IT security health assessments. We engage third parties to facilitate tabletop incident response and business continuity exercises. Additionally, we participate in various cybersecurity industry forums and have access to law enforcement analysis regarding current threats.

Our third-party risk management program is integrated into our Information Security Program within our ERM Program. The policies, procedures and practices applicable to the cybersecurity components of the third-party risk management program were developed and are maintained consistent with the FFIEC IT Examination Handbook, as well as guidance from our prudential regulators. We perform a risk assessment, including cyber threats, associated with use of third-party vendors and exercise appropriate due diligence before entering into a vendor arrangement. We also engage a third party to actively monitor our cybersecurity risks and gather threat intelligence of select vendors and their products and services. Additionally, we conduct information security assessments before sharing or allowing the hosting of sensitive data in computing environments managed by third parties. Our contracts governing third party engagements require certain security and privacy protections where applicable. All third parties with access to our information systems must review and acknowledge our Acceptable Use Policy before access is granted.

When a cybersecurity incident occurs, whether detected internally or from third-party cybersecurity incidents, we evaluate the incident for criticality across a range of contributing indicators, including service availability, impact to operations, and brand, regulatory and legal considerations, data sensitivity and direct financial impact. The potential impact of the incident, individually or in aggregate, is evaluated by the Chief Security Officer, or CSO, continuously across these criteria. We have

**<u>[**Table of Contents**](#ia7d84a7456464799a5bd4ecb9ee914c6_7)</u>**

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

escalation procedures to notify members of senior and executive management, the Board (or an applicable subset) and regulators in a timely manner based on the criticality of the cybersecurity incident. S&T also has in place incident response and business continuity plans. The Incident Response Program outlines the policies, procedures and technical measures for identifying an incident, assessing its nature and scope, minimizing and containing the impact, investigating the root cause and reporting, as applicable. S&T uses data from incidents to reassess risk, evaluate and implement any additional controls deemed necessary and measure the success of the incident response team. The Incident Response Program also includes staff training, annual updates and testing. The Business Continuity Plan defines the policies, procedures and technical measures to restore systems and critical operations. S&T also maintains business continuity plans for critical systems and applications managed or hosted by third-party vendors.

To date, risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have not materially affected us, including our business strategy, results of operations or financial condition. We may nevertheless be unsuccessful in the future in preventing or mitigating a cybersecurity incident that could have a material impact on our business, results of operations or financial condition. At December 31, 2025, management has assessed known cybersecurity incidents for potential materiality and disclosure using formal documented processes and has determined that there have been no material cybersecurity incidents, individually or in aggregate.

**Governance**

***Board Oversight***

The Risk Committee is appointed by the Board and is authorized to perform its functions in assisting the Board with fulfilling its fiduciary responsibilities with respect to its oversight and assessment of S&T's enterprise-wide risk management framework. The Risk Committee oversees risk from cybersecurity threats as a part of its oversight of the ERM Program. The Risk Committee regularly reviews reports from, and has discussions with, S&T's Chief Risk Officer, or CRO, Chief Operating Officer, or COO, Chief Information Officer, or CIO, CSO, and Director of Operational Risk Management regarding cybersecurity risks, the threat landscape, updates on incidents and reports on our investments in cybersecurity risk mitigation and governance. The Risk Committee chairperson reports activities and recommendations with respect to such matters to the Board as are relevant and deemed appropriate by the Risk Committee. In the event of a material cybersecurity event, the CSO is responsible for promptly reporting such incidents to the CRO, executive management and the Board. A special meeting of the Board will be held, as deemed necessary by the Chairperson of the Board in consultation with the Chair of the Risk Committee.

***Management's Role***

At the management level, the ERM Committee, CRO, COO, CIO, CSO and Director of Operational Risk Management are responsible for assessing and managing material risks from cybersecurity threats. The ERM Committee reports information to the Risk Committee on a quarterly basis, or more often as needed.

Risk Management leadership, which assists the ERM Committee in assessing and managing cybersecurity threats, include our CRO, COO, CIO, CSO and Director of Operational Risk Management. Our CRO who oversees the risk management information security program reports to our CEO, but has direct access to the Risk Committee. Our CRO is a Certified Public Accountant, holds a Certification in Risk Management Assurance and has over 25 years of financial services experience. Our COO has over 20 years of banking technology and operations experience, including serving as head of digital for a business unit at a large national bank. Our CSO reports to the CRO and has 18 years of information technology and cybersecurity experience, including prior roles as chief information officer, assistant director of information technology, chief information security officer and chief security officer in federal law enforcement and banking organizations. Our CIO has over 25 years of financial services, information technology, cybersecurity and emerging technologies experience. Our Director of Operational Risk Management has over 25 years of information technology and cybersecurity experience, including serving as a former chief information officer for a financial institution.

**Item 5. MARKET FOR REGISTRANT'S COMMON EQUITY, RELATED SHAREHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES**

**Stock Information**

Our common stock is listed on the NASDAQ Global Select Market System, or NASDAQ, under the symbol STBA. As of the close of business on February 24, 2026 we had approximately 2,194 shareholders of record. The number of record-holders does not reflect the number of persons or entities holding stock through mutual funds, exchange traded funds or in nominee name through banks, brokerage firms and other nominees.

**Dividends**

As discussed under "Our ability to pay dividends on our common stock may be limited." included in Item 1A. Risk Factors in Part I, the amount and timing of dividends is subject to the discretion of the Board and depends upon business conditions and regulatory requirements. The Board has the discretion to change the dividend at any time for any reason. The Board of Directors presently intends to continue the policy of paying quarterly cash dividends. The amount of any future dividends will depend on economic and market conditions, our financial condition and operating results and other factors, including applicable government regulations and policies. S&T's Board of Directors approved a quarterly cash dividend of $0.36 per share on January 28, 2026.

**Securities Authorized for Issuance under Equity Compensation Plans**

Certain information relating to securities authorized for issuance under equity compensation plans is set forth under the heading Equity Compensation Plan Information in Part III, Item 12 Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters of this Report.

**Purchases of Equity Securities** 

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. The following table is a summary of our purchases of common stock during the fourth quarter of 2025:

**Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

This section reviews our financial condition for each of the past two fiscal years and results of operations for each of the past three fiscal years. Management's discussion and analysis focuses on significant factors impacting the financial condition and results of operations for the year ended December 31, 2025 as compared to the year ended December 31, 2024. This discussion and analysis should be read in conjunction with our Consolidated Financial Statements and related notes within this Annual Report on Form 10-K. A similar discussion and analysis that compares the year ended December 31, 2024 to the year ended December 31, 2023 may be found in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations" on our Form 10-K for the year ended December 31, 2024 accepted by the Securities and Exchange Commission, or SEC, on February 28, 2025. Certain reclassifications have been made to prior periods to conform to the current period presentation.

 **Important Note Regarding Forward-Looking Statements**

This Annual Report on Form 10-K 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 elsewhere in this report, 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.

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

**Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

**Critical Accounting Policies and Estimates**

Our consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles, or GAAP. Application of these principles requires management to make estimates, assumptions and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions and judgments are based on information available as of the date of the consolidated financial statements; accordingly, as this information changes, the consolidated financial statements could reflect different estimates, assumptions and judgments. Certain policies are based, to a greater extent, on estimates, assumptions and judgments of management and, as such, have a greater possibility of producing results that could be materially different than originally reported.

Our most significant accounting policies are presented in Note 1. Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements included in Part II, Item 8 of this Report. These policies, along with the disclosures presented in the Notes to Consolidated Financial Statements, provide information on how significant assets and liabilities are valued in the consolidated financial statements and how those values are determined.

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. We currently view the determination of the ACL and goodwill to be critical accounting policies. We did not significantly change the manner in which we applied our critical accounting policies or developed related assumptions or estimates during 2025. We have reviewed these critical accounting estimates and related disclosures with the Audit Committee.

***Allowance for Credit Losses***

Our expected credit loss methodology requires consideration of a broader range of information to estimate expected credit losses over the lifetime of an asset. The ACL is a valuation reserve established and maintained by charges against operating income. It is an estimate of expected credit losses, measured over the contractual life of a loan, that considers historical loss experience, current conditions and forecasts of future economic conditions.

Management's evaluation process used to determine the appropriateness of the ACL is complex and requires the use of estimates, assumptions and judgments which are inherently subject to high uncertainty. The evaluation process combines several factors: historical loan loss experience, managements ongoing review of lending policies and practices, experience and depth of staff, quality of the loan grading system, the fair value of underlying collateral, concentration of loans to specific borrowers or industries, existing economic conditions and forecasts, segment specific risks and other quantitative and qualitative factors which could affect future credit losses. Our reasonable and supportable forecast is based primarily on the national unemployment forecast produced by the Federal Reserve and is for a period of two years. For periods beyond our two-year forecast, we revert to historical loss rates utilizing a straight-line method over a one-year reversion period. Because current economic conditions and forecasts can change and future events are inherently difficult to predict, the anticipated amount of estimated credit losses on loans and the appropriateness of the ACL could change significantly. It is challenging to estimate how potential changes in any one economic factor or input might affect the overall allowance because a wide variety of factors and inputs may be directionally inconsistent, such that improvement in one factor may offset deterioration in others.

In conjunction with our capital stress testing process, we consider different economic scenarios that impact the ACL. Among other balance sheet and income statement changes, our severely adverse scenario would have resulted in an increase to the ACL of approximately 107 percent. This severely adverse scenario shows how sensitive the ACL can be to key qualitative and quantitative assumptions underlying the overall ACL calculation. To the extent actual losses are higher than management estimates, additional provision for credit losses could be required and could adversely affect our earnings or financial position in future periods.

***Goodwill***

As a result of acquisitions, we have recorded goodwill in our Consolidated Balance Sheets. Goodwill represents the excess of the purchase price over the fair value of net assets acquired.

The acquisition method of accounting requires that assets acquired and liabilities assumed in business combinations are recorded at their fair values. This often involves estimates based on third-party valuations or internal valuations based on discounted cash flow analyses or other valuation techniques which are inherently subjective. Business combinations also typically result in goodwill which is subject to ongoing periodic impairment tests based on the fair values of the reporting units to which the acquired goodwill relates.

The carrying value of goodwill is tested annually for impairment each October 1st or more frequently if events and circumstances indicate that it may be impaired. We test for impairment by comparing the fair value of the reporting unit with its

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

**Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

carrying amount. An impairment charge would be recognized if the carrying amount exceeds the reporting unit's fair value. A qualitative assessment is performed to determine whether it is more likely than not that the reporting unit's fair value is less than it's carrying value. We perform a quantitative impairment test only if we conclude that it is more likely than not that a reporting unit's fair value is less than the carrying amount. Determining the fair value of a reporting unit is judgmental and involves the use of significant estimates and assumptions. The fair value of the reporting unit is determined by using both a discounted cash flow model and market based models. The discounted cash flow model has many assumptions including future earnings projections, a long-term growth rate and discount rate. The market based method calculates the fair value based on observed price multiples for similar companies. The fair values of each method are then weighted based on the relevance and reliability in the current economic environment.

Based upon our qualitative assessment performed for our annual impairment analysis as of October 1, 2025, we concluded that goodwill is not impaired.

Summary of Significant Accounting Policies in the Notes to Consolidated Financial Statements, which is included in Part II, Item 8 Financial Statements and Supplementary Data of this Report, discusses new accounting pronouncements that we have adopted and the expected impact of accounting pronouncements recently issued or proposed, but not yet required to be adopted.

**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, such as interest income on interest-earning assets, net interest income and net interest margin presented on a fully taxable equivalent, or FTE, basis (non-GAAP), the efficiency ratio (non-GAAP) and return on tangible shareholders' equity (non-GAAP).

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 following table reconciles interest and dividend income and net interest income per the Consolidated Statements of Net Income to interest income, net interest income and net interest margin on an FTE basis (non-GAAP) for the periods presented. 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 combining both taxable and non-taxable sources of interest income.

The efficiency ratio is noninterest expense divided by net interest income on an FTE basis (non-GAAP) which ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice, plus noninterest income adjusted to exclude losses on sales of securities and gains on Visa exchange. Below is a reconciliation of the non-GAAP efficiency ratio.

We earned net income of $134.2 million for 2025 compared to net income of $131.3 million in 2024. Diluted earnings per share, or EPS, was $3.49 in 2025 compared to $3.41 in 2024. The increase in both net income and EPS in 2025 can be attributed to an increase in net interest income offset by an increase in the provision for credit losses and noninterest expenses.

Net interest income increased $15.3 million, or 4.57 percent, to $350.1 million in 2025 compared to $334.8 million in 2024. Net interest income on an FTE basis (non-GAAP) increased $15.0 million, or 4.44 percent, compared to 2024. The net interest margin, or NIM, on an FTE basis (non-GAAP) increased 8 basis points to 3.90 percent in 2025 compared to 3.82 percent in 2024. The higher NIM (FTE) (non-GAAP), despite the declining interest rate environment, reflects the strategic repositioning of the balance sheet to be more interest rate neutral. NIM is reconciled to net interest margin adjusted to an FTE basis (non-GAAP) above in the "Explanation of Use of Non-GAAP Financial Measures" section of this Management's Discussion and Analysis, or MD&A.

The provision for credit losses increased $7.3 million to $7.4 million for 2025 compared to $0.1 million for 2024. The increase primarily related to higher net loan charge-offs offset by a lower required level of ACL. Net loan charge-offs were $14.5 million, or 0.18 percent of average loans, in 2025 compared to $8.3 million, or 0.11 percent of average loans, in 2024. Higher net charge-offs were primarily due to the resolution of nonperforming assets during the fourth quarter of 2025.

Noninterest income increased $2.9 million, or 6.0 percent, to $52.0 million in 2025 compared to $49.1 million in 2024. The increase primarily related to lower security losses of $2.3 million in 2025 compared to $7.9 million in 2024 offset by a $3.5 million gain from the exchange offer for Visa Class B-1 common stock in 2024.

Noninterest expense increased $7.9 million, or 3.6 percent, to $226.8 million in 2025 compared to $218.9 million in 2024. Expenses remained relatively stable with the most significant increase related to salaries and employee benefits which increased $5.7 million primarily due to higher salary and incentive costs. The efficiency ratio (non-GAAP) for 2025 was 55.74 percent compared to 55.99 percent for 2024. A reconciliation of the efficiency ratio (non-GAAP) is provided above in the "Explanation of Use of Non-GAAP Financial Measures" section of this MD&A.

The provision for income taxes remained relatively unchanged at $33.7 million in 2025 compared to $33.6 million in 2024. The effective tax rate decreased to 20.1 percent in 2025 compared to 20.4 percent in 2024. The decrease in the effective tax rate was primarily due to an increase in low income housing tax credits, or LIHTC, net of amortization.

**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.

As part of our interest rate risk management strategy, we use interest rate swaps to add stability to net interest income by managing our exposure to interest rate movements. During 2022, we entered into interest rate swaps with a total notional amount of $500.0 million with maturities ranging from three to five years. There were no new interest rates swaps entered into in 2023, 2024 or 2025. Our strategy is to reduce our exposure to variability in expected future cash flows related to interest payments on commercial loans that are currently indexed to the 1-month SOFR rate. Interest rates increased substantially in 2022 and 2023 followed by decreases in 2024 and 2025 resulting in an unrealized loss on the cash flow hedges of $1.6 million at December 31, 2025 which is reported in Accumulated Other Comprehensive Income (Loss), or AOCI, net of applicable taxes. This is an improvement of $5.9 million compared to the $7.5 million unrealized loss at December 31, 2024.

<sup>(1)</sup> *Tax-exempt interest income is on an FTE basis (non-GAAP) using the statutory federal corporate income tax rate of 21 percent.*

<sup>(2)</sup> *Taxable investment income is adjusted for the dividend-received deduction for equity securities.*

<sup>(3)</sup> *Nonaccruing loans are included in the daily average loan amounts outstanding.*

Net interest income on an FTE basis (non-GAAP) increased $15.0 million, or 4.44 percent, to $352.5 million in 2025 compared to $337.5 million in 2024. NIM on an FTE basis (non-GAAP) increased 8 basis points to 3.90 percent compared to 3.82 percent in 2024. The increases in net interest income on a FTE basis (non-GAAP) and NIM on an FTE basis (non-GAAP) were primarily due to the impact of lower interest rates on total interest-bearing liabilities and an improvement in our overall funding mix. Customer deposit growth in 2024 and 2025 has reduced our levels of borrowings and brokered deposits.

Interest income on an FTE basis (non-GAAP) remained relatively unchanged in 2025 compared to 2024 due to increased yield in the securities portfolio partially offset by yield declines in the loan portfolio. The average yield on securities increased 69 basis points compared to 2024 primarily due to the repositioning of $193.6 million of securities during 2024 and 2025. The average yield on loan balances decreased 22 basis points compared to 2024 due to lower interest rates. Average loan balances increased $221.2 million to $7.9 billion in 2025 compared to $7.7 billion in 2024. Overall, the FTE rate (non-GAAP) on interest-earning assets decreased 13 basis points compared to 2024.

Interest expense decreased $14.7 million to $166.4 million in 2025 compared to $181.1 million in 2024. The decrease in interest expense was primarily due to lower levels of borrowings and decreased interest rates. Average interest-bearing deposits

increased $246.8 million to $5.7 billion in 2025 compared to $5.5 billion in 2024. Average borrowings decreased $141.5 million to $211.8 million in 2025 compared to $353.2 in 2024 primarily due to an increase in deposits. Overall, the cost of interest-bearing liabilities decreased 30 basis points in 2025 compared to 2024.

**Provision for Credit Losses**

The provision for credit losses includes a provision for losses on loans and on unfunded loan 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 $7.3 million to $7.4 million for 2025 compared to $0.1 million for 2024. The increase was primarily due to higher net loan charge-offs and a $2.9 million increase in the reserve for unfunded loan commitments due to higher unused commitments in the construction portfolio. Partially offsetting the increase in the provision for credit losses was a lower level of ACL primarily related to a reduction in loss rates, lower criticized and classified loans and a decrease in the specific reserve for loans individually evaluated. The provision for credit losses included $1.2 million for the reserve for unfunded commitments for 2025 compared to negative $1.7 million for 2024. Net loan charge-offs for 2025 were $14.5 million, or 0.18 percent of average loans, compared to $8.3 million, or 0.11 percent of average loans, for 2024.

---

Noninterest income increased $2.9 million, or 6.0 percent, to $52.0 million compared to $49.1 million in 2024. The increase primarily related to lower security losses of $2.3 million in 2025 compared to $7.9 million in 2024 offset by a $3.5 million gain from the exchange offer for Visa Class B-1 common stock recognized in other noninterest income in 2024.

---

Noninterest expense was well controlled with an increase of $7.8 million, or 3.6 percent, to $226.8 million compared to $218.9 million in 2024. Salaries and employee benefits increased $5.7 million during 2025 primarily due to annual merit increases, higher incentives and increased restricted stock expense. Occupancy increased $1.1 million in 2025 due to increased maintenance and utility costs. Other noninterest expense increased $1.1 million compared to 2024 primarily related to higher employee related costs and loan related expenses.

**Provision for Income Taxes**

The provision for income taxes was unchanged at $33.7 million in 2025 compared to $33.6 million in 2024. The effective tax rate, which is total tax expense as a percentage of income before taxes, decreased to 20.1 percent in 2025 compared to 20.4 percent in 2024. The decrease in the effective tax rate in 2025 compared to 2024 was primarily due to an increase in LIHTC, net of amortization. We have generated an annual effective tax rate that is less than the statutory rate of 21 percent due to benefits resulting from tax-exempt interest, excludable dividend income, tax-exempt income on Bank Owned Life Insurance, or BOLI, and tax benefits associated with LIHTC which is partially offset by the proportional amortization method, or PAM.

**Financial Condition as of December 31, 2025**

Total assets increased $213.0 million to $9.9 billion at December 31, 2025 compared to $9.7 billion at December 31, 2024. Total portfolio loans increased $329.0 million, or 4.3 percent, to $8.1 billion at December 31, 2025 compared to December 31, 2024. The commercial loan portfolio increased $244.9 million and the consumer loan portfolio increased $84.1 million compared to December 31, 2024.

Securities remained relatively flat at December 31, 2025 compared to December 31, 2024. The securities portfolio was in a net unrealized loss position of $34.9 million at December 31, 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 was primarily due to a decline in interest rates from December 31, 2024.

Total deposits increased $175.7 million, or 2.3 percent, to $8.0 billion at December 31, 2025 compared to $7.8 billion at December 31, 2024. Customer deposits increased $220.5 million to $7.8 billion at December 31, 2025 compared to $7.6 billion at December 31, 2024. Brokered deposits decreased $44.8 million to $180.4 million at December 31, 2025 compared to $225.2 million at December 31, 2024.

Total borrowings increased $15.0 million to $265.3 million at December 31, 2025 compared to $250.3 million at December 31, 2024.

Total shareholders' equity increased by $83.6 million to $1.5 billion at December 31, 2025 compared to December 31, 2024. The increase was primarily due to net income of $134.2 million and other comprehensive income of $35.3 million offset by dividends of $53.0 million and repurchases of S&T common stock of $36.6 million which includes excise tax and commissions of $0.4 million. During the fourth quarter of 2025, 948,270 common shares were repurchased at an average price of $38.20 per share.

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. Security purchases are subject to an investment policy approved annually by our Board of Directors and administered through ALCO and our treasury function. Our entire securities portfolio is classified as available for sale. The portfolio primarily consists of structured agency-backed, fixed-income securities with limited credit exposure. Total securities available for sale at December 31, 2025 remained relatively flat compared to December 31, 2024.

At December 31, 2025, our securities portfolio was in a net unrealized loss position of $34.9 million compared to a net unrealized loss position of $71.7 million at December 31, 2024. At December 31, 2025, our securities portfolio had gross unrealized losses of $42.4 million offset by $7.5 million in gross unrealized gains compared to December 31, 2024, when total gross unrealized losses were $72.7 million offset by gross unrealized gains of $1.0 million.

Management evaluates the securities portfolio to determine if an ACL is needed each quarter. We did not record an ACL related to the securities portfolio at December 31, 2025 or December 31, 2024. The unrealized losses on debt securities were primarily attributable to changes in interest rates and not related to the credit quality of these securities. All debt securities were determined to be investment grade and paying principal and interest according to the contractual terms of the security at December 31, 2025. We do not intend to sell and it is more likely than not that we will not be required to sell any of the securities in an unrealized loss position before recovery of their amortized cost. We did not recognize any impairment charges on our securities portfolio in 2025, 2024 or 2023.

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.

We adhere to a General Lending Policy to maintain the quality of our loan portfolio. The policy delegates the authority to extend loans under specific guidelines and underwriting standards. The General Lending Policy is formulated by management and reviewed and ratified annually by the Board of Directors.

We attempt to limit our exposure to credit risk by diversifying our loan portfolio by segment, geography, collateral and industry and actively managing concentrations. When concentrations exist in certain segments, we assess the credit risk within those segments to determine if additional reserve is needed in the qualitative portion of the ACL. Total commercial loans represented 68.5 percent of total portfolio loans at December 31, 2025 compared to 68.2 percent at December 31, 2024. Within our commercial portfolio, the CRE and commercial construction portfolios combined comprised $4.0 billion, or 72.5 percent, of total commercial loans and 49.6 percent of total portfolio loans at December 31, 2025 compared to $3.7 billion, or 70.8 percent, of total commercial loans and 48.3 percent of total portfolio loans at December 31, 2024.

We lend primarily in Pennsylvania and the contiguous states of Ohio, New York, West Virginia, New Jersey, Delaware and Maryland. The majority of our commercial and consumer loans are made to businesses and individuals in these states resulting in a geographic concentration. We believe our knowledge of these markets outweighs the geographic concentration risk. Our operating knowledge at the local and regional level is derived from our front-line connection to the customer and our understanding of their businesses. We also have a portfolio management group that utilizes multiple data sources including

customer information, publicly available data and subscription service data to assess risk on an on-going basis and strong overall risk management practices which help us understand and evaluate concentration risk. Our CRE and commercial construction portfolios have exposure outside of the primary states in which we operate of 3.5 percent of the combined portfolios and 1.7 percent of total portfolio loans at December 31, 2025 and 3.9 percent of the combined portfolios and 1.9 percent of total portfolio loans at December 31, 2024.

Total portfolio loans increased $329.0 million, or 4.2 percent, to $8.1 billion at December 31, 2025 compared to $7.7 billion at December 31, 2024. As of December 31, 2025, 60.0 percent of our total loans were variable rate loans and 40.0 percent were fixed rate loans compared to 62.0 percent variable rate loans and 38.0 percent fixed rate loans at December 31, 2024.

Commercial loans represented 68.5 percent of our total portfolio loans at December 31, 2025 and 68.2 percent at December 31, 2024. Commercial loans increased $244.9 million to $5.5 billion at December 31, 2025 compared to $5.3 billion at December 31, 2024 related to increases of $238.8 million in CRE and $27.2 million in commercial construction offset by a decrease of $21.1 million in C&I.

Consumer loans represented 31.5 percent of our total portfolio loans at December 31, 2025 and 31.8 percent at December 31, 2024. Consumer loans increased $84.1 million to $2.5 billion at December 31, 2025 compared to $2.5 billion at December 31, 2024 primarily due to an increase of $97.6 million in consumer real estate offset by a decrease of $13.5 million in consumer installment loans.

We originate traditional fixed rate mortgage loans and adjustable rate mortgages with a maximum amortization term of 30 years. The loan to value, or LTV, policy guideline is 80 percent for residential first lien mortgages. Higher LTV loans may be approved within unique program guidelines. We may originate home equity loans with a lien position that is second to unrelated third-party lenders, but normally only to the extent that the combined LTV considering both the first and second liens does not exceed 100 percent of the fair value of the property. Combo mortgage loans consisting of a residential first mortgage and a home equity second mortgage are also available.

We had historically originated and sold loans to the secondary market, primarily to Fannie Mae, in order to mitigate interest-rate risk associated with holding lower rate, long-term residential mortgages in the loan portfolio and to generate fee revenue from sales and servicing of the loans. Beginning in 2023, our strategy changed whereby we held more mortgages on our balance sheet versus selling these loans in the secondary market. This shift in strategy was due to pricing in the secondary mortgage market and the desire to shift the mix of our loan portfolio to more fixed rate loans. We continue to monitor our strategy and may shift back to selling more residential mortgages into the secondary market in future periods. At December 31, 2025, our servicing portfolio of mortgage loans that we originated and sold into the secondary market was $591.6 million compared to $648.9 million at December 31, 2024.

**Off-Balance Sheet Arrangements**

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 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. Many of the commitments are expected to expire without being drawn upon, therefore, the total commitment amounts do not necessarily represent future cash requirements.

See Note 16. Commitments and Contingencies in Part II, Item 8. Financial Statements and Supplementary Data of this Report for details on the allowance for credit losses on unfunded commitments.

**Credit Quality**

On a quarterly basis, criticized asset meetings are held to monitor all special mention and substandard loans greater than $1.5 million and all business banking special mention and substandard loans greater than $0.5 million to establish action plans for these loans. These loans typically represent the highest risk of loss to us. We monitor these loans through regular contact with the borrower, review of current financial information and other documentation, review of all loan or potential loan restructures or modifications and the regular reevaluation of assets held as collateral. We also have a quarterly criticized asset meeting for the retail portfolio to review delinquent and nonaccrual loans as well as individual portfolio reviews such as unsecured, private banking and first payment default loans.

Additional credit risk management practices include periodic loan reviews, at least annually, and updates of our lending policies and procedures to support sound underwriting practices and portfolio management through portfolio stress testing. Our business banking relationships are monitored through portfolio management software that identifies credit risk indicators. We have portfolio monitoring groups that perform annual reviews of all commercial and business banking relationships greater than $1.5 million and a quarterly review of our watch rated portfolio. Our credit risk review process serves to independently monitor credit quality and assess the effectiveness of credit risk management practices to provide oversight of all corporate lending activities. The credit risk review function has the primary responsibility for assessing commercial credit administration and credit decision functions of consumer and mortgage underwriting, as well as providing input to the loan risk rating process.

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.

The following table presents delinquency and nonaccrual loans as of December 31:

Nonaccrual loans increased to $55.6 million at December 31, 2025 compared to $27.9 million at December 31, 2024. The increase in nonaccrual loans was primarily due to the addition of three commercial relationships totaling $25.3 million that were placed on nonaccrual during the three months ended December 31, 2025. A specific reserve of $1.6 million was added for one of the commercial relationships based on an updated collateral evaluation.

Closed-end installment loans, amortizing loans secured by real estate and any other loans with payments scheduled monthly are reported past due when the borrower is in arrears two or more monthly payments. Other multi-payment obligations with payments scheduled other than monthly are reported past due when one scheduled payment is due and unpaid for 30 days or more. We monitor delinquency on a monthly basis, including early-stage delinquencies of 30 to 89 days past due for early identification of potential problem loans.

**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 a loan 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.

Our charge-off policy for commercial loans requires that loans and other obligations that are not collectible be promptly charged-off when the loss is confirmed, regardless of the delinquency status of the loan. We may elect to recognize a partial charge-off when management has determined that the value of collateral or present value of expected future cash flows is less than the remaining investment in the loan. A loan or obligation does not need to be charged-off, regardless of delinquency status, if (i) management has determined that sufficient collateral exists to protect the remaining loan balance and a strategy exists to liquidate the collateral, or (ii) management has determined that the present value of expected future cash flows is sufficient to protect the remaining loan balance. Management may also consider a number of other factors to determine when a charge-off is appropriate. These factors may include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the status of a bankruptcy proceeding;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the value of collateral and probability of successful liquidation; and/or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the status of adverse proceedings or litigation that may result in collection.

Consumer loans are evaluated for charge-off after the loan becomes 90 days past due. Unsecured loans are fully charged off and secured loans are charged down to the estimated fair value of the collateral less the cost to sell.

The following table presents activity in the ACL for each of the three years presented below:

Significant to our ACL is a higher concentration of commercial loans. The ability of borrowers to repay commercial loans is dependent upon the success of their business and general economic conditions. Due to the greater potential for loss within our commercial portfolio, we monitor the commercial 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 rated special mention or substandard have potential or well-defined weaknesses not generally found in high quality, performing loans and require attention from management to limit loss.

The ACL was $93.2 million, or 1.15 percent of total portfolio loans, at December 31, 2025 compared to $101.5 million, or 1.31 percent of total portfolio loans, at December 31, 2024. The decrease in the ACL of $8.3 million is primarily related to a reduction in loss rates, lower criticized and classified loans and a decrease in the specific reserve for loans individually evaluated.

**Federal Home Loan Bank and Other Restricted Stock**

At December 31, 2025, we held FHLB of Pittsburgh stock of $16.0 million compared to $15.2 million at December 31, 2024. This investment is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value. We hold FHLB stock because we are a member of the FHLB of Pittsburgh. The FHLB requires members to purchase and hold a specified level of FHLB stock based upon the members' asset values, level of borrowings and participation in other programs offered. Stock in the FHLB is non-marketable and is redeemable at the discretion of the FHLB. Members do not purchase stock in the FHLB for the same reasons that traditional equity investors acquire stock in an investor-owned enterprise. Rather, members purchase stock to obtain access to the products and services offered by the FHLB. Unlike equity securities of traditional for-profit enterprises, the stock of the FHLB does not provide its holders with an opportunity for capital appreciation because, by regulation, FHLB stock can only be purchased, redeemed and transferred at par value. We reviewed and evaluated the FHLB capital stock for impairment at December 31, 2025. The FHLB exceeds all required capital ratios. Additionally, we considered that the FHLB has been paying dividends and actively redeeming stock throughout 2025 and 2024. Accordingly, we believe sufficient evidence exists to conclude that no impairment existed at December 31, 2025.

We have a strong core deposit base with noninterest-bearing demand deposits representing 27.2 percent of total deposits at December 31, 2025 compared to 28.1 percent of total deposits at December 31, 2024. Total deposits increased $175.7 million, or 2.3 percent, at December 31, 2025 compared to December 31, 2024. Total customer deposits increased $220.5 million, or 2.9 percent, from December 31, 2024 due to growth in certificates of deposit and money market. Total brokered deposits decreased $44.8 million from December 31, 2024 due to growth in customer deposits. Brokered deposits are an additional source of funds utilized by ALCO as a way to diversify funding sources, as well as manage our funding costs and structure.

As a member of the IntraFi network, we are able to offer our customers insurance coverage on interest-bearing demand, money market and certificate of deposit balances in excess of the FDIC insurance limits. IntraFi balances decreased $7.6 million to $317.3 million at December 31, 2025 compared to $324.8 million at December 31, 2024.

We have total uninsured deposits of $2.7 billion, or 33.7 percent of our total deposit base compared to $2.6 billion, or 33.5 percent, at December 31, 2024. Included in uninsured deposits is $333.6 million of fully collateralized, municipal deposits, or 4.2 percent of our total deposit base.

**Item 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

**Wealth Management Assets**

The fair value of the S&T Bank Wealth Management assets under administration, which are not accounted for as part of our assets, was $2.1 billion at December 31, 2025 and $2.0 billion at December 31, 2024. S&T Bank Wealth Management consists of S&T Trust which acts as a fiduciary by managing wealth for individuals and families and S&T Financial Services offers retirement and financial planning services. At December 31, 2025, assets under administration consisted of $0.6 billion in S&T Trust and $1.5 billion in S&T Financial Services compared to $0.7 billion in S&T Trust and $1.3 billion in S&T Financial Services at December 31, 2024.

 **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 December 31, 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 Reserve Discount Window through the Borrower-in-Custody Program, federal funds lines with other financial institutions and the brokered deposit market.

Available borrowing capacity exceeds uninsured deposits of $2.7 billion at December 31, 2025 and $2.6 billion at December 31, 2024. The following table summarizes borrowing funding sources available as of the dates presented:

At December 31, 2025, we had available borrowing capacity of $3.9 billion, $2.1 billion at the Federal Reserve and $1.8 billion at the FHLB of Pittsburgh. We believe that these funding sources will provide adequate resources to fund our short-term and long-term operating and financing needs. In addition, our ability to access capital markets provides additional sources of funding with respect to strategic investing opportunities. Our access to and the availability of funds in the future will be affected by many factors, including, but not limited to our financial condition and prospects, the liquidity of the overall capital markets and the current state of the economy.

In the normal course of business, we enter into various contractual obligations which require future payments that could impact our liquidity and capital resources. We also utilize interest rate swaps to add stability and manage exposure to interest rate movements, under which we are required to either receive cash from, or pay cash to, counterparties depending on changes in interest rates. Derivative contracts are carried at fair value representing the net present value of expected future cash receipts or payments based on market rates as of the balance sheet date.

<sup>(1)</sup> *Excludes interest*

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, with little or no loss in value, 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 December 31, 2025, S&T Bank had $852.2 million in highly liquid assets which consisted primarily of $105.2 million in interest-bearing deposits with banks and $746.0 million in unpledged securities. This resulted in a highly liquid assets to total assets ratio of 8.6 percent at December 31, 2025 compared to 9.7 percent at December 31, 2024. Refer to Note 12. Tax Credit Equity Investments, Note 13. Deposits, Note 14. Short Term Borrowings, Note 15. Long Term Borrowings and Subordinated Debt and Note 7. Right-Of-Use Assets and Lease Liabilities to the consolidated financial statements included in Part II, Item 8. Financial Statements and Supplementary Data and the Deposits and Borrowings section of this MD&A, for more details.

**Capital Resources**

Shareholders' equity increased $83.6 million, or 6.1 percent, to $1.5 billion at December 31, 2025 compared to $1.4 billion at December 31, 2024. The increase was primarily due to net income of $134.2 million and other comprehensive income of $35.3 million partially offset by dividends of $53.0 million and share repurchases of $36.6 million. The other comprehensive income was primarily due to a $28.9 million improvement in unrealized losses on our available-for-sale debt securities, net of tax and an improvement of $5.9 million in unrealized losses on our interest rate swaps, net of tax.

We continue to maintain a strong capital position with a leverage ratio of 12.18 percent as compared to the regulatory guideline of 5.00 percent to be well-capitalized and a risk-based Common Equity Tier 1 ratio of 14.32 percent compared to the regulatory guideline of 6.50 percent to be well-capitalized. Our risk-based Tier 1 and Total capital ratios were 14.62 percent and 16.19 percent which places us above the federal bank regulatory agencies' well-capitalized guidelines of 8.00 percent and 10.00 percent. Our ratios are also above the required minimum ratios after the capital conservation buffer, discussed further below, of common equity tier 1 risk-based capital ratio greater than 7.00 percent, tier 1 risk-based capital ratio greater than 8.50 percent and a total risk-based capital ratio greater than 10.50 percent. We believe that we have the ability to raise additional capital, if necessary.

On March 27, 2020, the regulators issued interim final rule, or IFR, "Regulatory Capital Rule: Revised Transition of the Current Expected Credit Losses Methodology for Allowances" in response to the disrupted economic activity from the spread of COVID-19. The IFR provides financial institutions that adopt CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital, followed by a three-year transition period to phase out the aggregate amount of the capital benefit provided by the initial two-year delay ("five-year transition"). We adopted CECL effective January 1, 2020 and elected to implement the five-year transition. As of December 31, 2025 we are fully transitioned.

Banking organizations are required to maintain a capital conservation buffer composed of common equity tier 1 capital in an amount greater than 2.50 percent of total risk-weighted assets. Banking organizations must maintain a common equity tier 1 risk-based capital ratio greater than 7.00 percent, a tier 1 risk-based capital ratio greater than 8.50 percent and a total risk-based capital ratio greater than 10.50 percent; otherwise, it will be subject to restrictions on capital distributions and discretionary bonus payments. The minimum capital requirements plus the capital conservation buffer exceeds the regulatory capital ratios required for an insured depository institution to be well-capitalized under the FDIC's prompt corrective action framework.

Federal regulators periodically propose amendments to the regulatory capital rules and the related regulatory framework and consider changes to the capital standards that could significantly increase the amount of capital needed to meet applicable standards. The timing of adoption, ultimate form and effect of any such proposed amendments cannot be predicted.

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. As of December 31, 2025, we had not issued any securities pursuant to the shelf registration statement.

**Inflation**

Inflation can have a significant impact on interest rates and, accordingly, can impact our financial performance. Inflation can influence our asset growth, deposits, noninterest income and expense and credit quality. As a result, we closely monitor the rate of inflation in the economy. We do so by analyzing our capability to respond to changing interest rates and our ability to manage noninterest income and expense. We monitor the mix of interest-rate sensitive assets and liabilities through ALCO in order to manage the impact of inflation and the level of interest rates on net interest income. We also manage the effects of inflation on S&T by reviewing the prices of our products and services, by introducing new products and services and by controlling overhead expenses. Additionally, management is aware of the potential impacts that inflation can have on our loan portfolio and our customer's ability to operate their businesses. We seek to minimize the various inflationary inputs through a robust annual review process and sensitivity analysis when considering extensions of credit. Additionally, we leverage our internal credit risk review in support of the current economic cycle. We continuously monitor our portfolio for potential and emerging risks. See Risk Factors in Item 1A for further information regarding the impact of inflation on the economy and on S&T.

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 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 show less improvement in the percentage change in pretax net interest income in the 1-12 month rates up scenarios when comparing December 31, 2025 to December 31, 2024 primarily because of changes to our funding mix and upcoming maturities within our receive-fixed balance sheet swap portfolio. The percentage change in pretax net interest income in the 1-12 month rates down scenarios remain relatively unchanged when comparing December 31, 2025 to December 31, 2024. Our rate shock analyses remain relatively unchanged in the percentage change in pretax net interest income in the 13-24 month scenarios when comparing December 31, 2025 to December 31, 2024. Our EVE analyses show an improvement in the rates up scenarios and a decline in the rates down scenarios when comparing December 31, 2025 to December 31, 2024 primarily due to an updated analysis that shows that our deposit retention is expected to be stronger than previously modeled.

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.

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

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**Nature of Operations**

S&T Bancorp, Inc., or S&T, was incorporated on March 17, 1983 under the laws of the Commonwealth of Pennsylvania as a bank holding company and has four active direct wholly owned subsidiaries, S&T Bank, 9th Street Holdings, Inc., STBA Capital Trust I and DNB Capital Trust II, and owns a 50 percent interest in Commonwealth Trust Credit Life Insurance Company, or CTCLIC.

We are presently engaged in non-banking activities through the following five entities: 9th Street Holdings, Inc.; S&T Bancholdings, Inc.; CTCLIC; S&T Insurance Group, LLC; and DN Acquisition Company, Inc. Our investment holding companies are 9th Street Holdings, Inc. and S&T Bancholdings, Inc. CTCLIC, which is a joint venture with another financial institution, acts as a reinsurer of credit life, accident and health insurance policies sold by S&T Bank and the other institution. S&T Insurance Group, LLC, through its subsidiaries, offers a variety of insurance products. DN Acquisition Company, Inc. was acquired with the DNB merger and was incorporated for the purpose of acquiring and holding other real estate owned, or OREO, acquired through foreclosure or deed in-lieu-of foreclosure, as well as bank-occupied real estate.

**Accounting Policies**

Our consolidated financial statements have been prepared in accordance with generally accepted accounting principles, or GAAP. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as well as disclosures of contingent assets and liabilities as of the dates of the balance sheets and revenues and expenses for the periods then ended. Actual results could differ from those estimates. Our significant accounting policies are described below.

**Principles of Consolidation**

The consolidated financial statements include the accounts of 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.

**Reclassification**

Amounts in prior years' financial statements and footnotes are reclassified whenever necessary to conform to the current period presentation. Reclassifications had no effect on our results of operations or financial condition.

**Business Combinations**

We account for business combinations using the acquisition method of accounting. All identifiable assets acquired, liabilities assumed and any non-controlling interest in the acquiree are recognized and measured as of the acquisition date at fair value. We record goodwill for the excess of the purchase price over the fair value of net assets acquired. Results of operations of the acquired entities are included in the Consolidated Statements of Net Income from the date of acquisition.

Acquired loans are recorded at fair value on the date of acquisition with no carryover of the related allowance for credit losses, or ACL. Determining the fair value of acquired loans involves estimating the principal and interest cash flows expected to be collected on the loans and discounting those cash flows at a market rate of interest. In estimating the fair value of our acquired loans, we consider a number of factors including loss rates, internal risk rating, delinquency status, loan type, loan term, prepayment rates, recovery periods and the current interest rate environment. The premium or discount estimated through the loan fair value calculation is recognized into interest income on a level yield basis over the remaining life of the loans.

Acquired loans, including those acquired in a business combination, are evaluated to determine if they have experienced more-than-insignificant deterioration in credit quality since origination. When the condition exists, these loans are referred to as purchased credit deteriorated, or PCD. An allowance is recognized for a PCD loan by adding it to the purchase price or fair value in a business combination. There is no provision for credit losses, or PCL, recognized upon acquisition of a PCD loan since the initial allowance is established through the purchase accounting. After initial recognition, the accounting for a PCD loan follows the credit loss model that applies to that type of asset. Purchased financial loans that do not have a more-than-significant deterioration in credit quality since origination are accounted for in a manner consistent with originated loans. An ACL is recorded with a corresponding charge to PCL. Subsequent to the acquisition date, the methods utilized to estimate the required ACL for these loans is similar to the method used for originated loans.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**Fair Value Measurements**

We use fair value measurements when recording and disclosing certain financial assets and liabilities. Available-for-sale 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, 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 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. Our policy is to recognize transfers between any of the fair value hierarchy levels at the end of the reporting period in which the transfer occurred.

The following are descriptions of the valuation methodologies that we use for financial instruments recorded at fair value on either a recurring or nonrecurring basis.

***Recurring Basis***

*Available-for-Sale Debt Securities*

We obtain fair values for debt securities from a third-party pricing service which utilizes several sources for valuing fixed-income securities. We validate prices received from our pricing service through comparison to a secondary pricing service and broker quotes. We review the methodologies of the pricing services which provide us with a sufficient understanding of the valuation models, assumptions, inputs and pricing to reasonably measure the fair value of our debt securities. The fair value of U.S. treasury securities are based on quoted market prices in active markets and are classified as Level 1. The market valuation sources for other debt securities include observable inputs rather than significant unobservable inputs and are classified as Level 2. The service provider utilizes pricing models that vary by asset class and include available trade, bid and other market information. Generally, the methodologies include broker quotes, proprietary models and extensive quality control programs.

*Equity Securities*

Marketable equity securities with quoted prices in active markets for identical assets are classified as Level 1. Marketable equity securities in markets that are not active are classified as Level 2.

*Securities Held in a Deferred Compensation Plan*

Securities Held in a Deferred Compensation Plan are reported at fair value with the gains and losses included in other noninterest income in our Consolidated Statements of Net Income. These assets are held in a deferred compensation plan and are invested in readily quoted mutual funds. Accordingly, these assets are classified as Level 1. Deferred compensation plan assets are reported in other assets in the Consolidated Balance Sheets.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

*Derivative Financial Instruments*

We use derivative instruments, including interest rate swaps that qualify as cash flow hedges, interest rate swaps for commercial loans with our customers, interest rate lock commitments and forward commitments related to the sale of mortgage loans in the secondary market. We calculate the fair value for derivatives using accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. Each valuation considers the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, such as interest rate curves and implied volatilities. We incorporate credit valuation adjustments into the valuation models to appropriately reflect both our own nonperformance risk and the respective counterparties' nonperformance risk in calculating fair value measurements. We consider the impact of master netting agreements and collateral postings with our counterparties to determine the credit valuation adjustment. Interest rate swaps are classified as Level 2. Interest rate lock commitments and forward commitments related to mortgage loans are classified as Level 3 due to significant unobservable inputs.

***Nonrecurring Basis***

*Loans Held for Sale*

Loans held for sale consist of 1-4 family residential loans originated for sale in the secondary market and, from time to time, certain loans transferred from the loan portfolio to loans held for sale, all of which are carried at the lower of cost or fair value. When the fair value of a loan held for sale is less than its cost, the loan is written down to fair value. In such cases, fair value is based on the principal or most advantageous market currently offered for similar loans using observable market data. Loans held for sale marked to fair value are classified as Level 2 if the fair value is determined using a sales or market approach and Level 3 if the fair value is determined using an income approach.

*Loans Individually Evaluated*

Loans that are individually evaluated to determine whether a specific allocation of ACL is needed are reported at the lower of amortized cost or fair value. Fair value is determined using either discounted cash flow, the loan's observable market price or the fair value of the collateral less estimated selling costs when the loan is collateral dependent and we expect to liquidate the collateral. However, if repayment is expected to come from the operation of the collateral, rather than liquidation, then we do not consider estimated selling costs in determining the fair value of the collateral. Collateral values are generally based upon appraisals by approved, independent state certified appraisers. Appraisals may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or our knowledge of the borrower and the borrower's business. If the fair value of loans individually evaluated is determined based on an independent, market based appraisal that uses market observable inputs it is classified as Level 2. If the fair value of loans individually evaluated is determined using an internal valuation, such as discounted cash flow, it is classified as Level 3.

*OREO and Other Repossessed Assets*

OREO and other repossessed assets obtained in partial or total satisfaction of a loan are recorded at fair value less cost to sell. Fair value, when recorded, is generally based upon appraisals by approved, independent state certified appraisers. Appraisals on OREO may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or other information available to us. If the fair value for OREO is determined based on an independent, market-based appraisal with market observable inputs it is classified as Level 2. If the fair value for OREO is determined using an internal valuation, it is classified as Level 3.

*Mortgage Servicing Rights*

MSRs are reported using the amortization method and are evaluated for impairment quarterly by comparing the carrying value to the fair value of the MSRs. The fair value of MSRs is determined by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSRs. MSRs are considered impaired if the carrying value exceeds fair value. The valuation model includes significant unobservable inputs; therefore, MSRs are classified as Level 3 when marked to fair value.

***Financial Instruments***

Fair value accounting guidance requires disclosure of the fair value of all of an entity's assets and liabilities that are considered financial instruments. The majority of our assets and liabilities are considered financial instruments. Many of these instruments lack an available trading market as characterized by a willing buyer and willing seller engaged in an exchange transaction. Also, it is our general practice and intent to hold our financial instruments to maturity and to not engage in trading or sales activities with respect to such financial instruments. For fair value disclosure purposes, we substantially utilize the fair value measurement criteria as required and explained above. In cases where quoted fair values are not available, we use present value methods to determine the fair value of our financial instruments.

*Cash and Cash Equivalents*

The carrying amounts reported in the Consolidated Balance Sheets for cash and due from banks, including interest-bearing deposits approximate fair value.

*Loans*

Our methodology to fair value loans includes an exit price notion. The fair value of loans is estimated using discounted cash flow analyses that utilize interest rates currently being offered for similar loans and adjusted for liquidity and credit risk. The valuation models include significant unobservable inputs; therefore, loans are classified as Level 3. The carrying amount of interest receivable approximates fair value.

*Federal Home Loan Bank, or FHLB, and Other Restricted Stock*

It is not practical to determine the fair value of our FHLB and other restricted stock due to the restrictions placed on the transferability of these stocks; it is presented at carrying value.

*Collateral Receivable*

Collateral receivable is cash that is made available to counterparties as collateral for our interest rate swaps. The carrying amount included in other assets in our Consolidated Balance Sheets approximates fair value.

*Deposits*

The fair values disclosed for deposits without defined maturities (e.g., noninterest and interest-bearing demand, money market and savings accounts) are by definition equal to the amounts payable on demand. Deposits without defined maturities are classified as Level 1. The carrying amounts for variable rate, fixed-term time deposits approximate their fair values. Estimated fair values for fixed rate and other time deposits are based on discounted cash flow analysis using interest rates currently offered for time deposits with similar terms. Fixed rate and other time deposits are classified as Level 2. The carrying amount of accrued interest approximates fair value.

*Short-Term Borrowings*

The carrying amounts of short-term borrowings approximate their fair values. Fair values are based on observable inputs in a secondary market; therefore, these are classified as Level 2.

*Long-Term Borrowings*

The fair values disclosed for fixed rate long-term borrowings are determined by discounting their contractual cash flows using current interest rates for long-term borrowings of similar remaining maturities. The carrying amounts of variable rate long-term borrowings approximate their fair values. Fair values are based on observable inputs in a secondary market; therefore, these are classified as Level 2.

*Junior Subordinated Debt Securities*

The interest rate on the variable rate junior subordinated debt securities is reset quarterly; therefore, the carrying values approximate their fair values. Fair values are based on observable inputs in a secondary market; therefore, these are classified as Level 2.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

*Collateral Payable* 

Collateral payable is cash that is received from counterparties as collateral for our cash flow hedges and interest rate swaps. The carrying amount included in other liabilities in our Consolidated Balance Sheets approximates fair value.

**Cash and Cash Equivalents**

We consider cash and due from banks, interest-bearing deposits with banks and federal funds sold as cash and cash equivalents.

**Securities**

We determine the appropriate classification of securities at the time of purchase. Debt securities are classified as available-for-sale with the intent to hold for an indefinite period of time, but may be sold in response to changes in interest rates, prepayment risk, liquidity needs or other factors.

A determination will be made on whether a decline in the fair value below the amortized cost basis is due to credit-related factors or noncredit-related factors. Any impairment that is not credit-related is recognized in Other Comprehensive Income (Loss), or OCI, net of applicable taxes. Credit-related impairment is recognized as an ACL on the balance sheet with a corresponding adjustment to provision for credit losses in the Consolidated Statements of Net Income. Both the allowance and the adjustment to net income can be reversed if conditions change. Our policy for credit impairment within the available-for-sale debt securities portfolio is based upon a number of factors, including but not limited to, the financial condition of the underlying issuer, the ability of the issuer to meet contractual obligations, the likelihood of the security's ability to recover any decline in its estimated fair value and whether management intends to sell the security or if it is more likely than not that management will be required to sell the investment security prior to the security's recovery of any decline in its estimated fair value.

Realized gains and losses on the sale of these securities are determined using the specific-identification method and are recorded within noninterest income in the Consolidated Statements of Net Income. Bond premiums are amortized to the call date, if any, and bond discounts are accreted to the maturity date, both on a level yield basis.

Equity securities are measured at fair value with net unrealized gains and losses recognized in other noninterest income in the Consolidated Statements of Net Income.

**Loans Held for Sale**

Loans held for sale consist of 1-4 family residential loans originated for sale in the secondary market and, from time to time, certain loans transferred from the loan portfolio to loans held for sale, all of which are carried at the lower of cost or fair value. If a loan is transferred from the loan portfolio to the held for sale category, any write-down in the carrying amount of the loan at the date of transfer is recorded as a charge-off against the ACL. Subsequent declines in fair value are recognized as a charge to other noninterest income. When a loan is placed in the held for sale category, we stop amortizing the related deferred fees and costs. The remaining unamortized fees and costs are recognized as part of the cost basis of the loan at the time it is sold. Gains and losses on sales of mortgage loans held for sale are included in other noninterest income in the Consolidated Statements of Net Income.

**Loans**

Loans are reported at the principal amount outstanding net of unearned income. Unearned income consists of net deferred loan origination fees and costs and a discount or premium on acquired loans. Loan origination fees and direct loan origination costs are deferred and amortized as an adjustment of loan yield over the lives of the loans without consideration of anticipated prepayments. If a loan is paid off, the remaining unaccreted or unamortized net origination fees and costs are immediately recognized into income. Accretion of discounts and amortization of premiums on loans are included in interest income in the Consolidated Statements of Net Income. Interest is accrued and interest income is recognized on loans as earned.

Closed-end installment loans, amortizing loans secured by real estate and any other loans with payments scheduled monthly are reported past due when the borrower is in arrears two or more monthly payments. Other multi-payment obligations with payments scheduled other than monthly are reported past due when one scheduled payment is due and unpaid for 30 days or more.

Generally, consumer loans are charged off against the ACL upon the loan reaching 90 days past due. Commercial loans are charged off as management becomes aware of facts and circumstances that raise doubt as to the collectability of all or a portion of the principal and when a confirmed loss exists.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**Nonaccrual Loans**

We stop accruing interest on a loan when the borrower's payment is 90 days past due. Loans are also placed on nonaccrual status when we have doubt about the borrower's ability to comply with contractual repayment terms, even if payment is not past due. When the interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. As a general rule, a nonaccrual loan may be restored to accrual status when its principal and interest is paid current and the bank expects repayment of the remaining contractual principal and interest, or when the loan otherwise becomes well secured and in the process of collection.

**Allowance for Credit Losses**

The ACL is a valuation reserve established and maintained by charges against operating income and is deducted from the amortized cost basis of loans to present the net amount expected to be collected on the loans. Loans, or portions thereof, are charged off against the ACL when they are deemed uncollectible. The ACL is an estimate of expected credit losses, measured over the contractual life of a loan, that considers our historical loss experience, current conditions and forecasts of future economic conditions. Determination of an appropriate ACL is inherently subjective and the ACL may change significantly from period to period.

The methodology for determining the ACL has two main components: evaluation of expected credit losses for certain groups of homogeneous loans that share similar risk characteristics and evaluation of loans that do not share similar risk characteristics with other loans and are individually evaluated.

The ACL for homogeneous loans is calculated using a life-time loss rate methodology with both a quantitative and a qualitative analysis that is applied on a quarterly basis. The ACL model is comprised of six distinct portfolio segments: 1) Commercial Construction, 2) Commercial Real Estate, or CRE, 3) Commercial and Industrial, or C&I, 4) Business Banking, 5) Consumer Real Estate and 6) Other Consumer. Each segment has a distinct set of risk characteristics monitored by management. We further evaluate the ACL at a disaggregated level which includes type of collateral and our internal risk rating system for the commercial and business banking segments and type of collateral, lien position and FICO score, for the consumer segments. Historical credit loss experience is the basis for the estimation of expected credit losses. Our quantitative model uses historical data back to the second quarter of 2009. We apply historical loss rates to pools of loans with similar risk characteristics. After consideration of the quantitative loss calculation, management applies qualitative adjustments to reflect the current conditions and reasonable and supportable forecasts not already reflected in the historical loss information at the balance sheet date. Our reasonable and supportable forecast is for a period of two years and is based on the unemployment forecast and management judgment. For periods beyond our two-year reasonable and supportable forecast, we revert to historical loss rates utilizing a straight-line method over a one year reversion period. The qualitative adjustments for current conditions are based upon changes in lending policies and practices, experience and ability of lending staff, quality of the bank's loan review system, value of underlying collateral, the existence of and changes in concentrations, other external factors and segment specific risks. These modified historical loss rates are multiplied by the outstanding principal balance of each loan to calculate a required reserve.

The ACL for individual loans begins with the use of normal credit review procedures to identify whether a loan no longer shares similar risk characteristics with other pooled loans and therefore, should be individually assessed. We evaluate all commercial loans greater than $1.0 million that meet the following criteria: 1) when it is determined that foreclosure is probable, 2) substandard, doubtful and nonaccrual loans when repayment is expected to be provided substantially through the operation or sale of the collateral, or 3) when it is determined by management that a loan does not share similar risk characteristics with other loans. Specific reserves are established based on the following three acceptable methods for measuring the ACL: 1) the present value of expected future cash flows discounted at the loan's original effective interest rate; 2) the loan's observable market price; or 3) the fair value of the collateral when the loan is collateral dependent. Our individual loan evaluations consist primarily of the fair value of collateral method because most of our loans are collateral dependent. Collateral values are discounted to consider disposition costs when appropriate. A specific reserve is established or a charge-off is taken if the fair value of the loan is less than the loan balance.

Our ACL Committee meets quarterly to verify the overall appropriateness of the ACL. Additionally, on an annual basis, the ACL Committee meets to validate our ACL methodology. This validation includes reviewing the loan segmentation, critical model assumptions, forecast and the qualitative framework. As a result of this ongoing monitoring process, we may make changes to our ACL to be responsive to the economic environment.

**Bank Owned Life Insurance**

We have purchased life insurance policies on certain executive officers and employees. We receive the cash surrender value of each policy upon its termination or benefits are payable to us upon the death of the insured. Changes in net cash surrender value are recognized in other noninterest income in the Consolidated Statements of Net Income.

**Premises and Equipment**

Premises and equipment, including leasehold improvements, are stated at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred, while improvements that extend an asset's useful life are capitalized and depreciated over the estimated remaining life of the asset. Land is carried at cost. Depreciation expense is computed using the straight-line method for financial reporting purposes and accelerated methods for income tax purposes over the estimated useful lives of the particular assets. Buildings have useful lives of 25 years, furniture and fixtures, computer equipment and software, other equipment and vehicles have useful lives of 5 years. Leasehold improvements are depreciated at the lesser of the estimated useful life of the asset (generally 15 years unless established otherwise) or the remaining term of the lease, including renewal options in the lease that are reasonably assured of being exercised. Depreciation expense is included in occupancy on the Consolidated Statements of Net Income. Long-lived assets are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. No events or changes in circumstances occurred during the years ended December 31, 2025 and 2024.

**Right-of-Use Assets and Lease Liabilities**

We determine if a contract is or contains a lease at inception. Leases are classified as either finance or operating leases. We recognize leases in our Consolidated Balance Sheets as right-of-use, or ROU, assets and related lease liabilities. Finance ROU assets are included in premises and equipment and related finance lease liabilities are included in long-term borrowings. Interest on finance lease liabilities is included in borrowings interest expense in our Consolidated Statements of Net Income. Operating lease ROU assets are included in other assets and related operating lease liabilities are included in other liabilities and lease and amortization expenses are included in occupancy expense in our Consolidated Statements of Net Income. Our lease liability is calculated as the present value of the lease payments over the lease term discounted using our estimated incremental borrowing rate with similar terms at commencement date. Lease terms include options to extend or terminate the lease when it is reasonably certain that we will exercise those options. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term for operating leases. Interest and amortization expenses are recognized for finance leases over the lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet and the related lease expense is recognized on a straight-line basis over the lease term in occupancy in our Consolidated Statements of Net Income. Lease and non-lease components are accounted for as a single lease component in our Consolidated Balance Sheet.

**Restricted Investment in Bank Stock**

FHLB stock is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value. We hold FHLB stock because we are a member of the FHLB of Pittsburgh. The FHLB requires members to purchase and hold a specified level of FHLB stock based upon on the member's asset value, level of borrowings and participation in other programs offered. Stock in the FHLB is non-marketable and is redeemable at the discretion of the FHLB. Members do not purchase stock in the FHLB for the same reasons that traditional equity investors acquire stock in an investor-owned enterprise. Rather, members purchase stock to obtain access to the low-cost products and services offered by the FHLB. Unlike equity securities of traditional for-profit enterprises, the stock of the FHLB does not provide its holders with an opportunity for capital appreciation because, by regulation, FHLB stock can only be purchased, redeemed and transferred at par value. Both cash and stock dividends are reported as income in dividends within investment securities in the Consolidated Statements of Net Income. FHLB stock is evaluated for impairment when events and circumstance indicate that impairment could exist.

**Goodwill and Other Intangible Assets**

As a result of acquisitions, we have recorded goodwill and identifiable intangible assets in our Consolidated Balance Sheets. Goodwill represents the excess of the purchase price over the fair value of net assets acquired. We have one reportable segment.

The carrying value of goodwill is tested annually for impairment each October 1st or more frequently if events and circumstances indicate that it may be impaired. A qualitative assessment is performed to determine whether it is more likely than not that the reporting unit's fair value is less than its carrying value. The qualitative assessment considers, among other factors, macroeconomic conditions, industry and market trends, changes in interest rates and regulatory conditions, overall financial performance relative to forecasts, changes in operating costs, entity-specific events and changes in the carrying amount of the reporting unit. We perform a quantitative impairment test only if we conclude that it is more likely than not that a reporting unit's fair value is less than the carrying amount. Determining the fair value of a reporting unit is judgmental and involves the use of significant estimates and assumptions. The fair value of the reporting unit is determined by using both a discounted cash flow model and a market based model. The discounted cash flow model has many assumptions including future earnings projections, a long-term growth rate and discount rate. The market based model calculates fair value based on

observed price multiples for similar companies. The fair values of each method are then weighted based on relevance and reliability in the current economic environment.

We determine the amount of identifiable intangible assets based upon independent core deposit and insurance contract valuations at the time of acquisition. Intangible assets with finite useful lives, consisting primarily of core deposit and customer list intangibles, are amortized using straight-line or accelerated methods over their estimated weighted average useful lives, ranging from 10 to 20 years. Intangible assets with finite useful lives are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. No such events or changes in circumstances occurred during the years ended December 31, 2025 and 2024.

**Variable Interest Entities**

Variable interest entities, or VIEs, are legal entities that generally either do not have equity investors with voting rights or that have equity investors that do not provide sufficient financial resources for the entity to support its activities. When an enterprise has both the power to direct the economic activities of the VIE and the obligation to absorb losses of the VIE or the right to receive benefits of the VIE, the entity has a controlling financial interest in the VIE. A VIE often holds financial assets, including loans, receivables or other property. The company with a controlling financial interest, the primary beneficiary, is required to consolidate the VIE into its Consolidated Balance Sheets. S&T has two wholly-owned trust subsidiaries, STBA Capital Trust I and DNB Capital Trust II, or the Trusts, for which it does not absorb a majority of expected losses or receive a majority of the expected residual returns. DNB Capital Trust II was acquired with the DNB merger. At inception, these Trusts issued floating rate trust preferred securities to the Trustees and used the proceeds from the sale to invest in junior subordinated debt securities issued by us. The Trusts pay dividends on the trust preferred securities at the same rate as the interest we pay on the junior subordinated debt held by the Trusts. The Trusts are VIEs with the third-party investors as their primary beneficiaries, and accordingly, the Trusts and their net assets are not included in our consolidated financial statements. However, the junior subordinated debt securities issued by S&T are included in liabilities in our Consolidated Balance Sheets.

**Tax Credit Equity Investments**

We have made investments directly in Low Income Housing Tax Credit, or LIHTC, partnerships formed with third parties. As a limited partner in these operating partnerships, we receive tax credits and tax deductions for losses incurred by the underlying properties. These investments are amortized in proportion to the income tax credits and other income tax benefits received. Our investments in Low Income Housing Partnerships, or LIHPs, represent unconsolidated VIEs and the assets and liabilities of the partnerships are not recorded on our balance sheet. We have determined that we are not the primary beneficiary of these VIEs because we do not have the power to direct the activities that most significantly impact the economic performance of the partnership nor do we have both the obligation to absorb expected losses and the right to receive benefits. We adopted ASU 2023-02, Accounting for Investments in Tax Credit Structures Using the proportional amortization method, or PAM, effective January 1, 2024 and elected to utilize PAM to account for these partnerships. As a result, these investments are recorded in other assets and the remaining funding commitment is recorded in other liabilities in our Consolidated Balance Sheets. Amortization expense is included in income tax expense in the Consolidated Statements of Net Income. Prior to adopting PAM, the cost method was used to account for these partnerships. These investments are included in other assets in our Consolidated Balance Sheets and amortization expense is included in other noninterest expense in the Consolidated Statements of Net Income for 2023.

**OREO and Other Repossessed Assets**

OREO and other repossessed assets are included in other assets in the Consolidated Balance Sheets and are comprised of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of a foreclosure. OREO and other repossessed assets are recorded at fair value less cost to sell at the time of acquisition and when subsequent declines in fair value occur. Subsequent declines in the fair value of OREO are recorded through a valuation allowance. Subsequent increases in the fair value reduce the valuation allowance, but only to the amount that does not exceed the OREO foreclosure date cost basis. Loan losses arising from the acquisition of any such property initially are charged against the ACL. Gains or losses realized upon disposition of these assets are recorded in other noninterest income or expense in the Consolidated Statements of Net Income depending on whether the net position is a gain or loss.

**Securities Held in a Deferred Compensation Plan**

A nonqualified deferred compensation plan is offered to certain management employees providing an opportunity to continue to defer income on a tax deferred basis in excess of annual contribution or compensation limits for qualified plans. The plan assets are held in a grantor trust, are legal assets of S&T and are beneficially owned by the participants. The assets are available to satisfy the claims of general creditors in the event we would need to file bankruptcy. Securities held in the nonqualified deferred compensation plan are recorded in other assets in the Consolidated Balance Sheets at fair value. A corresponding deferred compensation liability is recorded in other liabilities in the Consolidated Balance Sheets. Gains and losses related to the change in value of plan assets and the deferred compensation liability offset resulting in no impact to net income.

**Mortgage Servicing Rights**

MSRs are recognized as separate assets when a mortgage loan is sold. When initially recorded, MSRs represent the estimated fair value of future net cash flows expected to be realized for performing the servicing activities. The fair value of the MSRs is estimated by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSRs. Increases in mortgage loan prepayments reduce estimated future net servicing cash flows because the life of the underlying loan is reduced. MSRs are reported in other assets in the Consolidated Balance Sheets and are amortized into other noninterest income in the Consolidated Statements of Net Income in proportion to, and over the period of, the estimated future net servicing income of the underlying mortgage loans.

MSRs are evaluated for impairment based on the estimated fair value of those rights. MSRs are stratified by certain risk characteristics, primarily loan term and note rate. If temporary impairment exists within a risk stratification tranche, a valuation allowance is established through a charge to income equal to the amount by which the carrying value exceeds the estimated fair value. If it is later determined that all or a portion of the temporary impairment no longer exists for a particular tranche, the valuation allowance is reduced.

**Derivative Financial Instruments**

Derivatives are recognized as either other assets or other liabilities on the balance sheet at fair value. All derivatives are evaluated at inception to determine whether it is a hedging or non-hedging activity. The accounting for changes in the fair value of derivatives depends on whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting based on whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting.

Pursuant to our agreements with various financial institutions, we may receive collateral or may be required to post collateral based upon mark-to-market positions. Beyond unsecured threshold levels, collateral in the form of cash or securities may be made available to counterparties of interest rate swap transactions. Interest income on collateral receivable is included in loan interest income in the Consolidated Statements of Net Income. Interest expense on collateral payable is included in borrowings, junior subordinated debt securities and other interest expense in the Consolidated Statements of Net Income.

Derivatives contain an element of credit risk, the possibility that we will incur a loss because a counterparty, which may be a financial institution or a customer, fails to meet its contractual obligations. All derivative contracts with financial institutions may be executed only with counterparties approved by our Asset and Liability Committee, or ALCO, and derivatives with customers may only be executed with customers within credit exposure limits approved in accordance with our credit policy. We have entered into agreements with counterparty financial institutions which include master netting agreements that provide for the net settlement of all contracts with a single counterparty in the event of default. We elect, however, to account for all derivatives with counterparty institutions on a gross basis in the Consolidated Balance Sheets.

***Interest Rate Swaps Designated as Hedging Instruments***

As part of our interest rate risk management strategy, we use interest rate swaps to add stability to interest income and to manage exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for making variable rate payments over the life of the agreements without exchange of the underlying notional amount.

Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the earnings effect of the hedged forecasted transactions in a cash flow hedge. As long as the cash flow hedge continues to qualify for hedge accounting, the entire change in the fair value of the hedging instrument is recognized in Accumulated OCI, net of applicable taxes, and

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

reclassified into loan interest income as interest payments are received. The change in the fair value is included in the change in other liabilities in the Consolidated Statements of Cash Flows.

***Interest Rate Contracts with Customers***

Interest rate swaps are contracts in which a series of interest rate flows (fixed and variable) are exchanged over a prescribed period. The notional amounts on which the interest payments are based are not exchanged. These derivative positions relate to transactions in which we enter into an interest rate swap with a commercial customer, while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on the same notional amount at a fixed rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate loan, while we continue to receive a variable amount of interest on the loan. These agreements could have floors or caps on the contracted interest rates.

Interest rate swaps with customers and the corresponding offsetting interest rate swap with a financial institution are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives are recorded in current earnings and included in other noninterest income in the Consolidated Statements of Net Income and included in the change in other assets and other liabilities in the Consolidated Statements of Cash Flows.

***Interest Rate Lock Commitments and Forward Sale Contracts***

In the normal course of business, we sell originated mortgage loans into the secondary mortgage loan market. We also offer interest rate lock commitments to potential borrowers. The commitments are generally for a period of 60 days and guarantee a specified interest rate for a loan if underwriting standards are met, but the commitment does not obligate the potential borrower to close on the loan. Accordingly, some commitments expire prior to becoming loans. We may encounter pricing risks if interest rates increase significantly before the loan can be closed and sold. We may utilize forward sale contracts in order to mitigate this pricing risk. Whenever a customer desires these products, a mortgage originator quotes a secondary market rate guaranteed for that day by the investor. The rate lock is executed between the mortgagee and us and in turn a forward sale contract may be executed between us and the investor. Both the rate lock commitment and the corresponding forward sale contract for each customer are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives during the commitment period are recorded in current earnings and included in other noninterest income in the Consolidated Statements of Net Income.

**Treasury Stock**

The repurchase of our common stock is recorded at cost. Broker fees or commissions and an excise tax equal to one percent of the fair value of shares purchased are included in the cost of treasury stock. The excise tax is reduced by the fair market value of any reissuance of treasury stock occurring in the same taxable year. At the time of reissuance, the treasury stock account is reduced using the average cost method. Gains and losses on the reissuance of common stock are recorded in additional paid-in capital.

**Revenue Recognition - Contracts with Customers**

We earn revenue from contracts with our customers when we have completed our performance obligations and recognize that revenue when services are provided to our customers. Our contracts with customers are primarily in the form of account agreements. Generally, our services are transferred at a point in time in response to transactions initiated and controlled by our customers under service agreements with an expected duration of one year or less. Our customers have the right to terminate their service agreements at any time.

We do not defer incremental direct costs to obtain contracts with customers that would be amortized in one year or less. These costs are primarily salaries and employee benefits recognized as expense in the period incurred.

**Service charges on deposit accounts** - We recognize monthly service charges for both commercial and personal banking customers based on account fee schedules. Our performance obligation is generally satisfied and the related revenue recognized at a point in time or over time when the services are provided. Other fees are earned based on specific transactions or customer activity within the customers' deposit accounts. These are earned at the time the transaction or customer activity occurs.

**Debit and credit card services** - Interchange fees are earned whenever debit and credit cards are processed through third-party card payment networks. ATM fees are based on transactions by our customers' and other customers' use of our ATMs or other ATMs. Debit and credit card revenue is recognized at a point in time when the transaction is settled. Our performance obligation to our customers is generally satisfied and the related revenue is recognized at a point in time when the service is

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

provided. Third-party service contracts include annual volume and marketing incentives which are recognized over a period of twelve months when we meet thresholds as stated in the service contract.

**Wealth management services** - Wealth management services are primarily comprised of fees earned from the management and administration of trusts, assets under administration and other financial advisory services. Generally, wealth management fees are earned over a period of time between monthly and annually, per the related fee schedules. Our performance obligations with our customers are generally satisfied when we provide the services as stated in the customers' agreements. The fees are based on a fixed amount or a scale based on the level of services provided or amount of assets under management.

**Other fee revenue** - Other fee revenue includes a variety of other traditional banking services such as, electronic banking fees, letters of credit origination fees, wire transfer fees, money orders, treasury checks, check sale fees and transfer fees. Our performance obligations are generally satisfied at a point in time and fee revenue is recognized when the services are provided or the transaction is settled.

**Wealth Management Fees**

Assets held in a fiduciary capacity by our subsidiary bank, S&T Bank, are not our assets and are therefore not included in our consolidated financial statements. Wealth management fee income is reported in the Consolidated Statements of Net Income on an accrual basis.

**Stock-Based Compensation**

Stock-based compensation includes restricted stock units which are measured using the fair value at the time of issuance. Compensation expense for time-based restricted stock is recognized ratably over the period during which the recipient is required to provide service in exchange for the award. A Monte Carlo simulation is used to estimate the fair value of performance-based restricted stock with a market condition. Compensation expense for performance-based restricted stock is recognized ratably over the remaining vesting period if the likelihood of meeting the performance measure is probable. We estimate expected forfeitures when stock-based awards are granted and record compensation expense only for awards that are expected to vest.

**Pensions**

The expense for S&T Bank's qualified and nonqualified defined benefit pension plans is actuarially determined using the projected unit credit actuarial cost method. It requires us to make economic assumptions regarding future interest rates and asset returns and various demographic assumptions. We estimate the discount rate used to measure benefit obligations by applying the projected cash flow for future benefit payments to a yield curve of high-quality corporate bonds available in the marketplace and by employing a model that matches bonds to our pension cash flows. The expected return on plan assets is an estimate of the long-term rate of return on plan assets which is determined based on the current asset mix and estimates of return by asset class. We recognize in the Consolidated Balance Sheets an asset for the plan's overfunded status in other assets or a liability for the plan's underfunded status in other liabilities. Gains or losses related to changes in benefit obligations or plan assets resulting from experience different from that assumed are recognized as OCI in the period in which they occur. To the extent that such gains or losses exceed 10 percent of the greater of the projected benefit obligation or plan assets, they are recognized as a component of pension costs over the future service periods of actively employed plan participants. The funding policy for the qualified plan is to contribute an amount each year that is at least equal to the minimum required contribution, but not more than the maximum amount permissible for taxable plan sponsors. Our nonqualified plans are unfunded.

On January 25, 2016, the Board of Directors approved an amendment to freeze benefit accruals under the qualified and nonqualified defined benefit pension plans effective March 31, 2016. As a result, no additional benefits are earned by participants in those plans based on service or pay after March 31, 2016. The plan was previously closed to new participants effective December 31, 2007.

**Marketing Costs**

We expense all marketing-related costs, including advertising costs, as incurred.

**Income Taxes**

We estimate income tax expense based on amounts expected to be owed to the tax jurisdictions where we conduct business. On a quarterly basis, management assesses the reasonableness of our effective tax rate based upon our current estimate of the amount and components of net income, tax credits and the applicable statutory tax rates expected for the full year. We classify interest and penalties as an element of tax expense.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

Deferred income tax assets and liabilities are determined using the asset and liability method and are reported in other assets or other liabilities, as appropriate, in the Consolidated Balance Sheets. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities and recognizes enacted changes in tax rate and laws. When deferred tax assets are recognized, they are subject to a valuation allowance based on management's judgment as to whether realization is more likely than not.

Accrued taxes represent the net estimated amount due to taxing jurisdictions and are reported in other assets or other liabilities, as appropriate, in the Consolidated Balance Sheets. We evaluate and assess the relative risks and appropriate tax treatment of transactions and filing positions after considering statutes, regulations, judicial precedent and other information and maintain tax accruals consistent with the evaluation of these relative risks and merits. Changes to the estimate of accrued taxes occur periodically due to changes in tax rates, interpretations of tax laws, the status of examinations being conducted by taxing authorities and changes to statutory, judicial and regulatory guidance. These changes, when they occur, can affect deferred taxes, accrued taxes and the current period's income tax expense and can be significant to our operating results.

Tax positions are recognized as a benefit only if it is more likely than not that the tax position would be sustained in a tax examination with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50 percent likely of being realized on examination. No tax benefit is recorded for tax positions not meeting the more likely than not test.

**Earnings Per Share**

Basic and diluted earnings per share, or EPS, are calculated using the more dilutive of either the treasury stock method or the two-class method. Under the treasury stock method, the weighted average number of common shares outstanding is increased by the potentially dilutive common shares. Under the two-class method unvested share-based payment awards that contain nonforfeitable rights to dividends are considered participating securities. Income allocated to common shareholders is then divided by the weighted average number of common shares outstanding during the period. Potentially dilutive common shares are related to restricted stock and are excluded from the basic EPS calculation.

**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. Significant expenses reviewed by the CODM are consistent with what is presented in the Consolidated Statements of Net Income. Expenses included within other expenses in the Consolidated Statements of Net 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 on a prospective basis. The adoption of this ASU had no impact to the consolidated financial statements. See supplemental disclosures in the Consolidated Statements of Cash Flows and Note 18 Income Taxes for additional disclosure requirements related the adoption of these amendments.

***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.

***Interim Reporting (Topic 270)—Narrow-Scope Improvements***

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270)—Narrow-Scope Improvements to improve the navigability of the required interim disclosures and clarify when the guidance is applicable. The amendments also provide additional guidance on what disclosures should be provided in interim reporting periods. The amendments add to Topic 270 a principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The amendments in this update are effective for annual reporting period beginning after December 15, 2027, and interim reporting periods beginning after December 15, 2028. Early adoption is permitted. This ASU is not expected to have a material impact on disclosures.

**NOTE 2. EARNINGS PER SHARE**

Earnings per share is calculated using both the two-class and the treasury stock methods with the more dilutive method used to determine basic and diluted earnings per share. The treasury stock method was used to determine EPS in 2025 and the two-class method was used to determine EPS in 2024 and 2023. The two-class method is no longer applicable and shown for comparative purposes only.

**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. These assets and liabilities are recorded at the lower of cost or fair value in our consolidated financial statements and are remeasured only when events or circumstances indicate impairment. There were no liabilities measured at fair value on a nonrecurring basis at both December 31, 2025 and December 31, 2024. There was $10.6 million Level 3 and $5.3 million Level 2 individually evaluated loans measured at fair value on a nonrecurring basis during the year ended December 31, 2025. During the year ended 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 during the years ended December 31, 2025 and December 31, 2024 were as follows:

**NOTE 4. DIVIDEND AND LOAN RESTRICTIONS**

S&T is a legal entity separate and distinct from its banking and other subsidiaries. A substantial portion of our revenues consist of dividend payments we receive from S&T Bank. There are limitations on the payment of dividends by S&T Bank to S&T, as well as by S&T to its shareholders. The payment of common dividends by S&T is subject to certain requirements and limitations of Pennsylvania law. S&T Bank, in turn, is subject to state laws and regulations that limit the amount of dividends it can pay to us. In addition, both S&T and S&T Bank are subject to various general regulatory policies relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The Federal Reserve has indicated that banking organizations should generally pay dividends only if (i) the organization's net income available to common shareholders over the past year has been sufficient to fully fund the dividends, (ii) the prospective rate of earnings retention appears consistent with the organization's capital needs, asset quality and overall financial condition and (iii) the organization will continue to meet minimum capital adequacy ratios. The policy also provides that a banking organization should inform the Federal Reserve reasonably in advance of declaring or paying a dividend that exceeds earnings for the period for which the dividend is being paid or that could result in a material adverse change to the bank holding company's capital structure. Bank holding companies also are required to consult with the Federal Reserve before redeeming or repurchasing capital instruments when the bank holding company is experiencing financial weaknesses. Additionally, the Federal Reserve could prohibit or limit the payment of dividends by a bank holding company if it determines that payment of the dividend would constitute an unsafe or unsound practice.

S&T Bank is subject to affiliate transaction rules in Sections 23A and 23B of the Federal Reserve Act as implemented by the Federal Reserve's Regulation W, that limit the amount of transactions between itself and S&T or any other company or entity that controls or is under common control with any company or entity that controls S&T Bank, including for most purposes any financial or depository institution subsidiary of S&T Bank. Under these provisions, "covered" transactions, including making loans, purchasing assets, issuing guarantees and other similar transactions, between a bank and its parent company or any other affiliate, generally are limited to 10 percent of the bank subsidiary's capital and surplus, and with respect to all transactions with affiliates, are limited to 20 percent of the bank subsidiary's capital and surplus. Loans and extensions of credit from a bank to an affiliate generally are required to be secured by eligible collateral in specified amounts, and in general all affiliated transactions must be on terms consistent with safe and sound banking practices. Furthermore, in general, transactions between a bank and its affiliates must be on terms and conditions that are at least as favorable to the bank as the terms that would apply in comparable transactions between the bank and a third party. The Dodd-Frank Act expanded the affiliate transaction rules to broaden the definition of affiliate to include as covered transactions securities borrowing or lending, repurchase or reverse repurchase agreements and derivative activities, and to strengthen collateral requirements and limit Federal Reserve exemptive authority.

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 December 31, 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 December 31, 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 were four payment defaults on previously modified loans to borrowers experiencing financial difficulty in the amount of $3.9 million during the twelve months ended December 31, 2025 of which $3.4 million are 60-89 days past due as of December 31, 2025 compared to one payment default for $0.1 million in the same periods in 2024. Additionally, we had nine commitments to lend an additional $1.8 million to borrowers experiencing financial difficulty that had a modification during the twelve months ended December 31, 2025 and five commitments to lend an additional $0.8 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.

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

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

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.

Goodwill is reviewed for impairment annually or more frequently if it is determined that a triggering event has occurred. We performed a qualitative assessment for our annual impairment analysis as of October 1, 2025 and concluded that it is not more likely than not that fair value is less than carrying value. Based on this conclusion, a quantitative impairment test was not performed and we concluded that goodwill was not impaired. No events or circumstances since the October 1, 2025 annual impairment test were noted that would indicate goodwill was impaired at December 31, 2025.

The following table presents a summary of intangible assets as of the dates presented:

| Accumulated amortization | (29089) | (28285) |
| **Balance at End of Year** | $**2251** | $**3055** |

---

Intangible assets relate to core deposit and wealth management customer relationships resulting from acquisitions. We determined the amount of identifiable intangible assets for our core deposits based upon an independent valuation. Other intangible assets are evaluated for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. There were no triggering events requiring an impairment analysis to be completed in 2025.

Amortization expense on finite-lived intangible assets totaled $0.8 million, $1.0 million and $1.3 million for 2025, 2024 and 2023.

The following is a summary of the expected amortization expense for finite-lived intangible assets, assuming no new additions, for each of the five years following December 31, 2025 and thereafter:

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. We estimate that an additional $1.9 million will be reclassified as a decrease to interest income in the next 12 months. Our current interest rate swap agreements have three to five year terms with maturity dates extending into 2027.

Long-term borrowings are for original terms greater than one year and are comprised of FHLB advances and finance leases. Long-term FHLB advances are secured by the same type of loans as short-term FHLB advances. Total loans pledged as collateral at the FHLB were $3.0 billion at December 31, 2025. We were eligible to borrow up to an additional $1.8 billion based on qualifying collateral and up to a maximum borrowing capacity of $2.1 billion at December 31, 2025.

We own 100 percent of the common equity of STBA Capital Trust I and DNB Capital Trust II, or the Trusts. DNB Capital Trust II was acquired with the DNB merger. The Trusts were formed to issue mandatorily redeemable capital securities to third-party investors. The proceeds from the sale of the securities and the issuance of the common equity by the Trusts were invested in junior subordinated debt securities issued by us. The third-party investors are considered the primary beneficiaries of the Trusts; therefore, the Trusts qualify as VIEs, but are not consolidated into our financial statements. The Trusts pay dividends on the securities at the same rate as the interest paid by us on the junior subordinated debt held by the Trusts.

**NOTE 16. 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)* | **December 31, 2025** | **December 31, 2024** |

| Standby letters of credit | 67452 | 69558 |
| **Total** | $**2711591** | $**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.

**NOTE 17. REVENUE FROM CONTRACTS WITH CUSTOMERS**

The information presented in the following table presents the point of revenue recognition for revenue from contracts with customers.

The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate to income before income taxes. We ordinarily generate an annual effective tax rate that is less than the statutory rate of 21 percent primarily due to benefits resulting from certain partnership investments, such as low income housing and historic rehabilitation projects, tax-exempt interest, excludable dividend income and tax-exempt income on BOLI.

ASU 2023-09 was adopted effective January 1, 2025. This ASU requires enhanced disclosures and disaggregation of the effective tax rate. This ASU was adopted on a prospective basis, therefore prior period disclosures have not been adjusted.

We establish a valuation allowance when it is more likely than not that we will not be able to realize the benefit of the deferred tax assets. The valuation allowance is reviewed quarterly and adjusted based on management's assessment of realizable deferred tax assets. Management believes it is more likely than not that our deferred tax assets will be realized in future periods, except for the Pennsylvania net operating losses, or NOLs. Gross deferred tax assets were reduced by a valuation allowance of $4.1 million in 2025 compared to $3.8 million in 2024 related to Pennsylvania income tax NOLs. The Pennsylvania NOL carryforwards total $82.3 million and will expire in the years 2026-2045.

**Unrecognized Tax Benefits**

As of December 31, 2025, we had $2.1 million of unrecognized gross tax benefits. Gross tax benefits do not reflect the federal tax effect associated with state income tax amounts. The total amount of the net unrecognized tax benefits at December 31, 2025 that would have affected the effective tax rate, if recognized, was $1.7 million.

**NOTE 20. EMPLOYEE BENEFITS**

We maintain a qualified defined benefit pension plan, or Plan, covering substantially all employees hired prior to January 1, 2008. The benefits are based on years of service and the employee's compensation for the highest 5 consecutive years in the last 10 years through March 31, 2016 when the Plan was frozen. Contributions are intended to provide for benefits attributed to employee service to date and for those benefits expected to be earned in the future.

Our qualified and nonqualified defined benefit plans, or Plans, were amended to freeze benefit accruals for all persons entitled to benefits under the Plans in 2016. We will continue recording pension expense related to these plans, primarily representing interest costs on the accumulated benefit obligation and amortization of actuarial losses accumulated in the Plans, as well as income from expected investment returns on pension assets. Since the Plans have been frozen, no service costs are included in net periodic pension expense.

The following table summarizes the activity in the benefit obligation and Plan assets deriving the funded status:

| | **2025** | **2024** | **2023** |
| Discount rate | 5.58% | 5.03% | 5.41% |
| Expected return on assets | 5.71% | 5.18% | 5.72% |

---

We consider many factors when setting the assumed rate of return on Plan assets. As a general guideline the assumed rate of return is equal to the weighted average of the expected returns for each asset category and is estimated based on historical returns as well as expected future returns. The weighted average discount rate is derived from corporate yield curves.

S&T Bank's Retirement Plan Committee determines the investment policy for the Plan. In general, the targeted investment allocation is 5 percent to 15 percent return seeking and 85 percent to 95 percent liability hedging. A strategic allocation within each investment allocation is based on the Plan's duration, time horizon, risk tolerances, performance expectations and preferences. Investment managers have discretion to invest in any equity or fixed-income asset class, subject to the securities guidelines of the Plan's Investment Policy Statement. At this time, S&T Bank is not required to make a cash contribution to the Plan in 2026.

The following table provides information regarding estimated future benefit payments to be paid in each of the next five years and in the aggregate for the five years thereafter:

---

| | |
|:---|:---|
| *(dollars in thousands)* | **Amount** |
| 2026 | $5875 |

We maintain a Thrift Plan, a qualified defined contribution plan, in which substantially all employees are eligible to participate. We make matching contributions to the Thrift Plan up to 3.5 percent of participants' eligible compensation and may make additional profit-sharing contributions as provided by the Thrift Plan. Expense related to these contributions amounted to $3.0 million in 2025, $2.9 million in 2024 and $2.7 million in 2023.

**NOTE 21. INCENTIVE AND RESTRICTED STOCK PLAN AND DIVIDEND REINVESTMENT PLAN**

The 2021 Incentive Plan provides for cash performance awards and for granting incentive stock options, nonstatutory stock options, restricted stock, restricted stock units and appreciation rights. The 2021 plan replaced and superseded the S&T Bancorp, Inc. 2014 Incentive Plan. No new awards will be granted under the 2014 plan. A maximum of 1,000,000 shares of our common stock were available for awards granted under the 2021 Incentive Plan and the plan expires ten years from the date of board approval which occurred in May of 2021. Previously granted but forfeited shares are added to the shares available for issuance.

**Restricted Stock**

We periodically issue restricted stock to employees and directors pursuant to our 2021 Incentive Plan. Restricted stock awards are part of the compensation arrangements approved by the Compensation and Benefits Committee. Restricted shares granted under the plan consist of both time and performance-based restricted stock units. The awards are granted in accordance with performance levels set by the Compensation and Benefits Committee.

The following table provides information about restricted stock units granted for the periods presented:

---

| **Total Restricted Stock Grants** |  | **183831** | **165711** | **162677** |

---

Common stock is issued as vesting restrictions lapse which varies according to the terms of the vesting schedules in the award agreements. The vesting of time based awards is generally 1 to 3 years. The vesting of performance-based awards is based on S&T's achievement of relative return on average equity and total shareholder return, over a 3 year performance period compared to a peer group as defined in the award agreements. Restricted stock grants are forfeited if a grantee leaves S&T before the end of the vesting period except where accelerated vesting provisions are defined within the award agreements.

**NOTE 23. REGULATORY MATTERS**

We are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our consolidated financial statements. Under capital guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. Our capital amounts and classification are also subject to qualitative judgments by the regulators about risk weightings and other factors.

Under the applicable capital rules, S&T and S&T Bank are subject to the following risk-based capital ratios: a common equity tier 1, or "CET1", risk-based capital ratio, a Tier 1 risk-based capital ratio, which includes CET1 and additional Tier 1 capital, and a total capital ratio which includes Tier 1 and Tier 2 capital. CET1 is primarily comprised of the sum of common stock instruments and related surplus net of treasury stock, retained earnings, and certain qualifying minority interests, less certain adjustments and deductions, including with respect to goodwill, intangible assets, mortgage servicing assets and deferred tax assets subject to temporary timing differences. Additional Tier 1 capital is primarily comprised of noncumulative perpetual preferred stock, tier 1 minority interests and grandfathered trust preferred securities, if applicable. Tier 2 capital consists of instruments disqualified from Tier 1 capital, including qualifying subordinated debt, certain trust preferred securities, other preferred stock and certain hybrid capital instruments, and a limited amount of loan loss reserves up to a maximum of 1.25 percent of risk-weighted assets, subject to certain eligibility criteria.

------

**<u>[**Table of Contents**](#ia7d84a7456464799a5bd4ecb9ee914c6_7)</u>**

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

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

The capital rules require a minimum CET1 risk-based capital ratio of 4.5 percent, a minimum overall Tier 1 risk based capital ratio of 6.0 percent, and a total risk-based capital ratio of 8.0 percent. In addition, the capital rules require a capital conservation buffer of 2.5 percent above each of the minimum capital ratio requirements (CET1, Tier 1, and total risk-based capital), which must be met for a bank or bank holding company to be able to pay dividends, engage in share buybacks or make discretionary bonus payments to executive management without automatic restrictions. The capital conservation buffer is 2.50 percent, so a banking organization needs to maintain a CET1 capital ratio of at least 7 percent, a total Tier 1 capital ratio of at least 8.5 percent and a total risk-based capital ratio of at least 10.5 percent or it would be subject to restrictions on capital distributions and discretionary bonus payments to its executive management.

The leverage capital ratio, which serves as a minimum capital standard, is the ratio of Tier 1 capital to quarterly average total assets, less goodwill and other disallowed intangible assets. The required minimum leverage ratio for all banks and bank holding companies is 4 percent.

To be well-capitalized, we must maintain the following capital ratios:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• CET1 risk-based capital ratio of 6.5 percent or greater;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tier 1 risk-based capital ratio of 8.0 percent or greater;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total risk-based capital ratio of 10.0 percent or greater; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Tier 1 leverage ratio of 5.0 percent or greater.

**NOTE 25. SUBSEQUENT EVENTS**

On January 21, 2026, the Board of Directors of S&T Bancorp, Inc. authorized a new $100 million share repurchase program. The new program replaced the existing share repurchase program effective January 26, 2026, and is set to expire February 1, 2027. The remaining capacity of $13.8 million under the existing share repurchase program was terminated. The new program authorizes the share repurchase of S&T's common stock from time to time through a combination of open market and privately negotiated transactions up to the authorized $100 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, applicable securities laws and other legal and contractual requirements, as well as S&T's financial performance. The repurchase program does not obligate S&T to repurchase any particular number of shares and may be extended, modified or discontinued at any time. As of February 25, 2026, 856,900 shares were repurchased under the new plan, at an average price of $43.45 per share, for $37.2 million excluding excise tax and commissions.

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

**Report of Independent Registered Public Accounting Firm**

To the Shareholders and the Board of Directors of S&T Bancorp, Inc.

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of S&T Bancorp, Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of net income, comprehensive income, changes in shareholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 27, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matter** 

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosures to which it relates.

**Allowance for Credit Losses (ACL)**

---

| | |
|:---|:---|
| ***Description of the Matter*** | At December 31, 2025, the Company's gross portfolio of loans was $8.1 billion with an associated ACL of $93.2 million. As discussed in Notes 1 and 6 to the consolidated financial statements, the ACL is an estimate of expected credit losses, measured over the contractual life of a loan, that considers historical loss experience, current conditions and forecasts of future economic conditions. The methodology for determining the ACL has two main components: evaluation of expected credit losses for certain groups of homogeneous loans that share similar risk characteristics and an individual assessment of loans that do not share risk characteristics with other loans to determine if a specific reserve is appropriate.<br>The ACL for homogeneous loans is calculated using a life-time loss rate methodology with both a quantitative and a qualitative analysis that is applied on a quarterly basis. Management applies qualitative adjustments to reflect the current conditions and reasonable and supportable forecasts not already reflected in the historical loss information at the balance sheet date. Judgment was required by management to determine the segment specific risk and the reasonable and supportable forecast, which are both part of the qualitative allowance.<br>Auditing the ACL involves a high degree of subjectivity due to the segment specific risk and the reasonable and supportable forecast, which are both part of the qualitative allowance. Management's identification and measurement of the segment specific risk and the reasonable and supportable forecast are highly judgmental and could have a significant effect on the ACL. |
| ***How We Addressed the Matter in Our Audit*** | We obtained an understanding, evaluated the design, and tested the operating effectiveness of the Company's controls over the ACL process, which include, among others, management's review and approval controls designed to assess the need for and level of the segment specific risk and the reasonable and supportable forecast, which are both part of the qualitative allowance, and the controls related to the reliability of the data utilized to support management's assessment. |
|  | To test the segment specific risk and reasonable and supportable forecast, which are both part of the qualitative allowance, we evaluated the appropriateness of management's methodology and assessed the reasonableness of the adjustments and whether all relevant risks were reflected in the ACL.<br>Regarding the measurement of the segment specific risk and the reasonable and supportable forecast, we evaluated the completeness, accuracy and relevance of the underlying internal and external data utilized in management's estimate and considered the existence of additional or contrary information. <br>We evaluated the overall ACL, inclusive of the qualitative adjustments, and whether the amount appropriately reflects a reasonable estimate of expected credit losses by comparing the overall ACL to historical losses and ACL reserves established by peer banking institutions. |

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

**Report of Independent Registered Public Accounting Firm**

To the Shareholders and the Board of Directors of S&T Bancorp, Inc.

**Opinion on Internal Control Over Financial Reporting**

We have audited S&T Bancorp, Inc. and subsidiaries' internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, S&T Bancorp, Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of net income, comprehensive income, changes in shareholders' equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and our report dated February 27, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**<u>S&T BANCORP, INC.</u>**

**<u>MANAGEMENT INCENTIVE PLAN</u>**

1. PURPOSE

The purpose of the S&T Bancorp, Inc. Management Incentive Plan (the "Plan") is to provide eligible senior management of S&T Bancorp, Inc., S&T Bank, and/or any of its subsidiaries (collectively the "Bank") with an annual incentive opportunity designed to: (i) create focus on specific planned performance goals, (ii) deliver a portion of a competitive pay package in a form that is not fixed but varies in relation to the performance of S&T Bancorp, Inc. and (iii) serve as a vehicle for recruitment and retention.

2. PLAN ADMINISTRATION

The Plan will be administered by the Compensation and Benefits Committee of the Board of Directors of the Bank (the "Committee").

The Committee may interpret, add, amend or rescind any rules and regulations necessary or appropriate for administration of the Plan, and make such determinations and take such action as it deems necessary or advisable. Any such interpretation, determination or other action made or taken by the Committee shall be final, binding and conclusive.

The Chief Executive Officer (CEO) may (i) recommend employees eligible to participate in the Plan, (ii) review individual and total award payments, and (iii) provide recommendations to the Committee regarding awards to executive officers with the exception of awards to the CEO.

The Committee may delegate the administrative responsibility for communicating and implementing the Plan, record keeping of Participant information, the calculation of individual award payments, and the distribution of approved award payments.

3. ELIGIBILITY

Participation in the Plan will be limited to those senior managers and other key contributors who are in positions in which their decisions, actions and counsel, in the sole discretion of the Committee, have been determined to be appropriate for Plan participation pursuant to its stated purpose.

Unless the Committee determines otherwise, employees of the Bank that participate in <u>any other cash incentive plan sponsored by the Bank</u> will not be eligible for participation under the Plan.

------

4. PARTICIPATION

Prior to the start of each Plan Year, or as soon as practical thereafter, the Committee will approve for Plan participation the list of eligible positions and the incumbents of these approved eligible positions for that Plan Year. Upon approval, Participants will be notified of their Plan participation, their Incentive Target Percentages, and the factors that will determine their earned incentive awards.

Following the start of a Plan Year, but before such year has ended, the Committee may, in its sole discretion, decide to include as Participants, employees who have become incumbents of eligible positions during the Plan Year as a result of hire, transfer, or promotion. If a Participant should commence participation during a Plan Year after the Plan Year has commenced, his/her Incentive Opportunity Earned Amount will be pro- rated based on the number of full days remaining in the Plan Year (starting with the first date he/she becomes a Plan Participant) over the full number of days of the entire Plan Year.

See Exhibit A for employee positions that have been approved by the Committee for Plan participation.

5. INCENTIVE TARGET PERCENTAGES

Participants will have an opportunity to earn additional compensation over and above their current Base Salary Rate. The Committee will establish specific incentive opportunities which will be expressed as a percentage of each Participant's Base Salary Rate during a given Plan year.

See Exhibit A for Incentive Target Percentages that have been approved by the Committee.

6. SHAREHOLDER PROTECTION FEATURE

Notwithstanding any other provisions in the Plan, payouts under the Plan will not occur for any Plan Year if the Bank falls below well capitalized capital ratio requirements established by regulatory authorities, determined as of and up to the date that any payment would ordinarily occur pursuant to the Plan's provisions.

7. PAY/PERFORMANCE LINKAGE

Prior to the beginning of each Plan Year, or as soon thereafter as practical, the CEO and/or senior executives selected by the CEO will recommend Performance Measures and Performance Standards to the Committee in one or both of the following two areas: Bank and unit/individual objectives. At the same time, a Weighting percentage will be established for each measure as recommended by the CEO to the Committee.

Performance Measures, Performance Standards and Weightings must be approved by the Committee.

See Exhibit A for performance criteria approved by the Committee.

------

8. DETERMINATION OF AWARDS

Following each Plan Year, and subject to the Shareholder Protection Feature, the performance of all Plan participants will then be reviewed by the Committee. Based on these performance assessments and subject to the approval by the Committee, awards to each Participant will be determined in the manner described in Exhibit A. Subject to the Shareholder Protection Feature, the Committee may, in its discretion, adjust (up or down, including to zero) the amount of an award otherwise determined in the manner described in Exhibit A, if such an adjustment is determined by the Committee to be consistent with shareholder interests. In addition, the CEO has the discretion to reduce an award to an amount (including to zero) should individual performance warrant.

9. PAYMENT OF AWARDS

Payment of each Participant's incentive award will be made pursuant to the provisions as described in Exhibit A.

l0.&nbsp;&nbsp;&nbsp;&nbsp;[INTENTIONALLY OMITTED]

ll.&nbsp;&nbsp;&nbsp;&nbsp;TERMINATION OF EMPLOYMENT

Notwithstanding anything herein to the contrary, if a Participant should terminate employment from the Bank due to death or disability (as those terms are defined in the Bank's qualified retirement plan) prior to payment of any incentive award under the Plan, the Committee in its sole discretion may pay an award (pro-rated or otherwise).

However, if a Participant should terminate employment from the Bank prior to payment of any incentive award under the Plan for any reason other than death or disability, participation will cease as of the effective date of termination, and no award will be paid.

l2.&nbsp;&nbsp;&nbsp;&nbsp;NO RIGHT OF CONTINUED EMPLOYMENT

Neither the establishment of the Plan nor the payment of any award hereunder nor any other action related to the Plan shall be held or construed to confer upon an employee the right to continued employment by the Bank or affect any right which the Bank may have to terminate the employment of any employee.

l3.&nbsp;&nbsp;&nbsp;&nbsp;FUTURE PARTICIPATION NOT GUARANTEED

Participation in the Plan by an employee in any Plan Year shall not be held or construed to confer upon the employee the right to participate in the Plan in any subsequent Plan Year.

l4.&nbsp;&nbsp;&nbsp;&nbsp;BREACH OF EMPLOYMENT RELATIONSHIP

Notwithstanding the provisions of the Plan, if the Committee in its sole discretion and judgment determines that a Participant has violated the Bank's Code of Conduct rules, policies or practices prior to the actual payment of any amount due under the Plan, the Bank will not be obliged to make any payment.

------

l5.&nbsp;&nbsp;&nbsp;&nbsp;AWARDS NOT ASSIGNABLE

Payments pursuant to the Plan will not be transferable or assignable by a Participant, except by will or by the laws of descent and distribution. Any other attempted assignment or alienation of a payment shall be void and of no force or effect.

l6.&nbsp;&nbsp;&nbsp;&nbsp;INCENTIVE AWARD RESERVES

No funds shall be set aside or reserved for payment of any awards under the Plan. Any obligation by the Bank to a Participant under the Plan will be unfunded and will be paid from the general assets and general funds of the Bank.

l7.&nbsp;&nbsp;&nbsp;&nbsp;RIGHT TO PAYMENT

In order to be paid an award for a given Plan Year, a Participant must be actively employed by the Bank on the actual date of payment as described in Exhibit A.

l8.&nbsp;&nbsp;&nbsp;&nbsp;RELATIONSHIP TO OTHER PLANS

Except as provided in Section 3 hereof, participation in this Plan will not affect an employee's eligibility to participate in any other benefits or compensation programs of the Bank. Any awards made pursuant to the Plan will not be used in determining the benefits provided under any other plan or program of the Bank unless such an inclusion is specifically provided for under the Plan. To the extent not prohibited by the Internal Revenue Code, ERISA, and/or any other legislative or regulatory requirements, the awards will be includable as eligible compensation in calculating benefits in the Bank's qualified Retirement and Thrift Plans and in the related non-qualified excess plans to the extent so provided in said plans.

l9.&nbsp;&nbsp;&nbsp;&nbsp;AMENDMENT OF THE PLAN

The Committee may amend or terminate this Plan at any time. The Committee may amend or terminate the rights of any Participant under the Plan at any time prior to the distribution of award payments. The Committee may amend or modify the Plan or the terms of any award at any time to the extent necessary to comply with all legal or regulatory requirements.

20. EFFECTIVE DATE

The Plan, as amended and restated, is effective as of January 1, 2026, and continues in effect throughout the year until terminated by the Committee.

21.[INTENTIONALLY OMITTED]

22.[INTENTIONALLY OMITTED]

------

23. CLAWBACK PROVISION

Any payment made under this Plan to a Plan Participant is subject to provision for recovery or ''clawback'' by the Bank if the payment was based on materially inaccurate financial statements (which includes, but is not limited to, statements of earnings, revenues, or gains) or any other materially inaccurate performance metric criteria. Whether a financial statement or performance metric criteria is materially inaccurate depends on all the facts and circumstances. However, for this purpose, a financial statement or performance metric criteria shall be treated as materially inaccurate with respect to any employee who knowingly engaged in providing inaccurate information (including knowingly failing to timely correct inaccurate information) relating to those financial statements or performance metrics. Otherwise, with respect to a performance criteria, whether the inaccurate measurement of the performance or inaccurate application of the performance to the performance criteria is material depends on whether the actual performance or accurate application of the actual performance to the performance criteria is materially different from the performance required under the performance criteria or the inaccurate application of the actual performance to the performance criteria.

The Bank must exercise its clawback rights except to the extent it demonstrates that it is unreasonable to do so, such as, for example, if the expense of enforcing the rights would exceed the amount recovered. Such determination shall be made at the discretion of the Committee.

For the purpose of this section, an incentive payment is deemed to be made to a Participant when the Participant obtains a legally binding right to that payment.

24. OTHER REQUIREMENTS

This Plan is not intended to be subject to requirements nor create rights under ERISA. In addition, to the extent any other legislative or regulatory developments arise that requires additional restrictions to the awards, unpaid amounts under the Plan will be adjusted in order to comply with any such requirements. The Plan is intended to comply with the requirements of Section 409A of the Internal Revenue Code (including the exceptions thereto) to the extent applicable, and the Committee shall administer and interpret the Plan in accordance with such requirements. In no event whatsoever shall the Committee or the Bank be liable for any additional tax, interest or penalties that may be imposed on a Participant by Section 409A of the Internal Revenue Code or any damages for failing to comply with Section 409A.

**EXHIBIT A: 2026 PLAN YEAR SPECIFICATIONS**

<u>PARTICIPATION</u>

Employees of the Bank are eligible to participate in the Plan in the indicated Tier as approved by the Committee in its discretion.

<u>MINIMUM GATEWAY REQUIREMENT</u>

In addition to the Shareholder Protection Feature of the Plan, the Plan is operational only if the Bank achieves a Return on Average Equity (ROAE) for 2026 of at least 5%.

<u>INCENTIVE TARGET PERCENTAGES AND PLAN COMPONENTS</u>

The amount payable to a Plan Participant for the Plan Year (the MIP Award Earned) will be based on Actual Performance. The Incentive Target Percentage is a percentage of the Base Salary Rate. If the above Minimum Gateway Requirement and the Shareholder Protection Feature are both met, the MIP Award Earned for each Plan Participant will be based on Plan Components. The 2026 Incentive Target Percentages and Plan Components are as follows:

---

| | | | |
|:---|:---|:---|:---|
| <br>**Tier** | | <br>**Plan Component**  | <br>**Plan Component**  |
| <br>**Tier** | **Target** | **Corporate** | **Individual** |

| 5 | &nbsp;&nbsp;25% | 70% | 30% |
| 6 | &nbsp;&nbsp;15% | 60% | 40% |

---

------

<u>PERFORMANCE MEASURES AND WEIGHTING</u>

The MIP Award Earned will be based on the Corporate Award Component and the Individual Award Component comprised of pre-established performance measures.

The Corporate Award Component is comprised of the following three pre-established Performance Measures and Weightings:

---

| | | |
|:---|:---|:---|
| **Metric Category** | &nbsp;&nbsp;&nbsp;&nbsp;**Goal** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**Weighting** |
| Profitability | &nbsp;&nbsp;&nbsp;Net Income | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;50% |
| Pre-provision net revenue | &nbsp;&nbsp;&nbsp;PPNR /Avg Assets | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;30% |
| Asset Quality | &nbsp;&nbsp;Quarterly Average of NPA / (Total Loans + OREO) | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;20% |

---

The Individual Award Component is comprised of two to four unit/individual Performance Measures and Standards as determined by the CEO and/or senior executives selected by the CEO. The Individual Component may payout up to a 100% achievement level.

These Performance Measures for the Corporate Award Component and the Individual Award Component combined have the following Weightings for each Tier:

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Corporate Award Component** | **Corporate Award Component** | **Corporate Award Component** | **Corporate Award Component** |
| **Tier** | &nbsp;&nbsp;&nbsp;&nbsp;**Net Income** | &nbsp;&nbsp;&nbsp;&nbsp;**PPNR** | &nbsp;&nbsp;&nbsp;**Credit Quality** | &nbsp;&nbsp;**Individual** |

<u>2026 CORPORATE PERFORMANCE METRICS AND PAYOUT AS A PERCENTAGE OF TARGET</u>

The specific Performance Levels, Measures, Standards, Weightings, and Payout Level Percentages are as follows:

---

| | | | |
|:---|:---|:---|:---|
| **Performance Measures and Performance Standards** | **Performance Measures and Performance Standards** | **Performance Measures and Performance Standards** | **Performance Measures and Performance Standards** |
| <br>**Performance Level** | &nbsp;&nbsp;<br>**PPNR**<br>**Ratio** | **Asset Quality** | **Payout Level Percentage of Allocated Target (a)** |
| **Below Threshold** | &nbsp;&nbsp;Below % | Above % | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;0% |
| **Threshold** | $&nbsp;&nbsp;% | % | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;25% |
| **Target** | $&nbsp;&nbsp;% | % | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;100% |
| **Maximum** | &nbsp;&nbsp;% | % | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;175% |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(a)** The Payout Level Percentage will vary for each Performance Measure depending on Actual Performance, and its payout curve rises continuously from Threshold to Target and from Target to Maximum. Therefore, to determine awards between Threshold and Target and Target and Maximum, linear interpolation would be utilized.

<u>DETERMINATION OF AWARDS</u> (See Exhibit B for an example)

The Committee will determine if payments under the Plan are permissible pursuant to the Shareholder Protection Feature and the Minimum Gateway Requirement as described in the Plan. If not determined to be permissible by the Committee, payments will not occur. If there are no prohibitions based on the Shareholder Protection Feature and the Minimum Gateway Requirement, payouts for each Plan Participant will be determined as follows:

**<u>Step 1:</u>** A Participant's Base Salary Rate is multiplied by the Incentive Target Percentage to determine his/her Incentive Target Amount.

**<u>Step 2:</u>** Pursuant to the Bank's Form 10K filing for the fiscal year that coincides with the Plan Year, the Payout Level Percentage is determined for each <u>Corporate Award</u> <u>Component</u> Performance Measure by comparing Actual Performance with the pre- established Performance Standards.

**<u>Step 3:</u>** The Payout Level Percentage for the <u>Individual Award Component</u> for each Plan Participant is determined by the CEO and/or senior executives selected by the CEO (and by the Committee in the case of the CEO and by the Committee in consultation with the Audit Committee in the case of the CAE), after the respective Plan Year, based on the Participant's Actual Performance during the Plan Year relative to the pre-established unit/individual Performance Measures and Standards.

**<u>Step 4:</u>** Each Performance Measure Weighting is multiplied by its respective Payout Level

Percentage to calculate the Weighted Award Percentage Earned for each Performance Measure.

**<u>Step 5:</u>** The Incentive Target Amount (calculated in Step 1) is multiplied by the sum of the Weighted Award Percentage Earned for the three Performance Measures to calculate the MIP Award Earned. For employees hired within the Plan year, the Participant's MIP Award Earned will be prorated based on the number of days employed within the Year. Any adjustment up or down to the Participant's MIP Award Earned for the Leadership Expectation is applied to calculate the proposed MIP Award Earned.

**<u>Step 6:</u>** Once the proposed MIP Award Earned has been calculated for all Plan Participants pursuant to the above steps, a list of each Participant with his/her proposed MIP Award Earned (indicating the Corporate and Individual Award Components, including amounts attributable to each applicable Performance Measure) will be prepared for the Committee's review and approval. The list will include the rationale for determining adjustments made to any Earned Individual Awards, if applicable.

<u>PAYMENT OF AWARDS</u>

Upon the Committee's approval of proposed awards, payouts will occur as follows (subject to the Right to Payment provision as described below):

For all Plan Participants to whom no restrictions apply with respect to paying or accruing incentives, 100% of amounts are payable in cash.

Notwithstanding anything to the contrary (including but not limited to any other plan or agreement), no Participant deferral elections shall be permitted in respect of awards under the Plan for the 2026 Plan Year.

<u>RIGHT TO PAYMENT</u>

A Participant must be actively employed by the Bank on the actual payment date in order to receive a payment under the Plan. However, if a Participant should terminate employment from the Bank prior to payment of any incentive award under the Plan due to death or disability, the Committee in its sole discretion may pay an award (pro-rated or otherwise). For all Plan Participants to whom no restrictions apply with respect to paying or accruing incentives, the payouts of their cash awards will be made in the calendar year in which the determination of entitlement to the award is made by the Committee.

## Exhibit 19.1

**S&T BANCORP, INC. POLICY** #603 - Insider Trading Policy

**POLICY TYPE:** Corporate

**DATE ISSUED/REVISED**: 7/30/2025

**<u>ISSUING DEPARTMENT</u>**<u>: Executive Page 1 of 12</u>

**I.<u>PURPOSE</u>**

S&T Bancorp, Inc. (the "Company") has adopted this Insider Trading Policy (the "Policy") that prohibits trading based on material, nonpublic information regarding S&T Bancorp, Inc., S&T Bank, and their respective subsidiaries (together, "S&T") or other companies ("Inside Information"). This Policy applies to officers, directors, director emeriti, and all other employees of, or consultants to, S&T, as well as the spouse, children or other relatives living in the same household of such persons ("family members"), any other persons living in the same household, and any other person or entity whose securities trading decisions are influenced or controlled by any of the foregoing. This Policy will continue to apply to any person whose employment or relationship with S&T terminates as long as the individual possesses Inside Information obtained in the course of employment or a relationship with S&T. This Policy should be read in conjunction with S&T's Corporate Policy #601 (Code of Conduct) and #604 (Prohibition on Disclosure of Material Nonpublic Information).

This Policy also requires the safeguarding of all nonpublic information, even if that information is not material and therefore not considered Inside Information. See Section V below.

**II.<u>PROHIBITION OF INSIDER TRADING</u>**

**<u>A.</u>**<u>Use of Material, Nonpublic Information By S&T Personnel</u>

No person subject to this Policy shall effect any transaction (whether a purchase or sale) in (1) S&T securities (including without limitation, acquisitions and dispositions of common stock by purchase, sale or gift, and transactions in employee benefits plans) while in possession of Inside Information about S&T or (2) any security (including options) of another public company while in possession of Inside Information about that company which has become known through the relationship with S&T. This Policy also forbids purchases or sales made by another person, on the basis of Inside Information, for the benefit of or at the request of an individual subject to this Policy.

Trades executed pursuant to a valid Rule 10b5-1 Plan (defined below) will not violate this Policy. See Section VI below.

<u>B.</u><u>Tipping</u>

This Policy forbids "tipping" others as to the desirability of buying or selling S&T securities on the basis of Inside Information. Recommending sales or purchases of the securities to which the Inside Information relates, even without disclosing the basis for the recommendation, is prohibited. This applies to "tipping" one's spouse or other relatives as well as anyone else. It is illegal under the federal securities laws to disclose (or "tip") Inside Information to another person who subsequently uses that information for his or her profit in effecting securities transactions. Consequently, S&T personnel must not disclose Inside Information (or any other nonpublic information, even if that information is not material) to another person unless (1) that person has

**DATE ISSUED/REVISED**: 7/30/2025

**<u>ISSUING DEPARTMENT</u>**<u>: Executive Page 2 of 12</u>

a need to know such information in connection with his or her employment or supervisory responsibilities within S&T (2) that person is employed by a firm retained by S&T (e.g., a law, accounting or other firm) and such person needs to know the information in connection with the services that his or her firm is providing to S&T, or (3) that person is employed by a company which has entered into a confidentiality agreement with S&T and needs to know the information in connection with the matter that is the subject of the agreement.

**III.<u>WHEN INFORMATION IS "MATERIAL"</u>**

It is not possible to define all categories of Inside Information. In general, information is "material" if its disclosure to the public would likely affect investors' decisions to purchase or sell the securities of the issuer in question or might have an effect on the market for the issuer's securities generally. In other words, information is material if there is a substantial likelihood that a reasonable investor would consider it important in deciding whether to buy, hold or sell a security. Any information that could reasonably be expected to affect the price of the security is material.

While it may be difficult under this standard to determine whether particular nonpublic information is material, there are various categories of information that are particularly sensitive and, as a general rule, should always be considered material. Examples of Inside Information may include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.Financial results or other earnings information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.Unpublished financial reports or projections;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.Defaults under agreements or actions by creditors, customers or suppliers relating to a company's credit standing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.Major changes in previously disclosed financial information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.The possibility of mergers, acquisitions, takeovers, tender offers, joint ventures or the possible initiation of a proxy fight;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;f.Changes in S&T's securities (e.g., defaults in senior securities, calls of securities for redemption, repurchase plans, stock splits, or decreases or increases in dividends;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;g.Information about current or proposed significant changes in operations or business plans (such as marketing and pricing plans), or about significant financial restructuring;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;h.Extraordinary borrowings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;i.Financial liquidity or credit quality problems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;j.Significant changes in management or relations among major stockholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;k.The purchase or sale of substantial assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;l.The possibility of a private or public offering of securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;m.Material cyber incidents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;n.Significant disputes, claims of litigation developments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;o.The possibility of a bankruptcy, recapitalization or other reorganization; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;p.Any other information which is likely to have a significant impact on S&T's financial results or stock price.

**POLICY TYPE:** Corporate

**DATE ISSUED/REVISED**: 7/30/2025

**<u>ISSUING DEPARTMENT</u>**<u>: Executive Page 3 of 12</u>

When in doubt, the information involved should be presumed to be material and therefore Inside Information.

**IV.<u>WHEN INFORMATION IS NONPUBLIC</u>**

Information that has not been disclosed broadly to the marketplace is nonpublic. To show that information is public, there should be evidence that it has been widely disseminated. Information would generally be deemed widely disseminated if it has been disclosed in a press release through news wire services such as PR Newswire, AP, UPI or Reuters; or in a filing with the SEC, such as Forms 8-K, 10-Q or 10-K.

**V.<u>SAFEGUARDING INFORMATION</u>**

Determining whether nonpublic information is Inside Information is difficult and will depend upon an analysis of complex facts and circumstances. Individuals should assume that any nonpublic information about S&T, or any other public company, is material. When in doubt whether any information is material or nonpublic, consult the Chief Financial Officer ("CFO"), or in his or her absence, the Chief Executive Officer ("CEO"). A determination by the CFO or CEO, as applicable, regarding material nonpublic information does not constitute legal advice, and is not a guarantee that a transaction while in possession of such information will not be subject to later challenge by a third party.

Nonpublic information relating to S&T is the property of S&T, and the unauthorized disclosure of that information is forbidden. In order to safeguard S&T's nonpublic information, and to minimize the possibility that an employee will violate the law or this Policy, the following guidelines and procedures have been adopted:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.All nonpublic information relating to S&T business should be handled on a need-to-know basis. Such information should not be discussed with any person who does not need to know such information for purposes of conducting S&T business. Friends and relatives are among the persons with whom confidential information should not be discussed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Whenever nonpublic information must be disclosed to an employee or representative, the recipient of such information should be apprised of the confidential nature of the information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.Nonpublic information should not be discussed in hallways, elevators or other public places (such as airplanes or restaurants) where conversations might be overheard and inadvertent disclosure should not be made through use of devices in speaker mode when discussions can be overheard.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.In order to prevent access by unauthorized persons, confidential documents should be stored appropriately when not being used, and other appropriate precautions should be taken. These may include using sealed envelopes, marking documents "Confidential," shredding documents, and using secure email and other appropriate computer security measures.

**<u>ISSUING DEPARTMENT</u>**<u>: Executive Page 4 of 12</u>

**VI.TRADING PURSUANT TO Rule 10b5-1 PLANS**

Notwithstanding the trading preclearance requirement discussed below in Section X, a Covered Person (defined below) is not required to preclear a transaction in S&T securities if such transaction is executed pursuant to a valid contract, instruction or plan that provides an affirmative defense pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934, as amended (a "Rule 10b5-1 Plan").

Rule 10b5-1 provides an affirmative defense to certain insider trading violations when a transaction in securities is consummated in accordance with a Rule 10b5-1 Plan. A Rule 10b5-1 Plan allows a person to trade even when in possession of material, nonpublic information, as long as the plan meets all of the requirements of Rule 10b5-1. This rule provides for the plan having one of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expressly specified amounts, prices and dates of trades;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a written formula or algorithm, or computer program, for determining amounts, prices, and dates of trades; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• does not permit the employee, officer, director, or director emeriti to exercise any subsequent influence over how, when or whether to effect trades; provided, in addition, that any other person who, pursuant to the contract, instruction, or plan, did exercise such influence must not have been aware of the material nonpublic information when doing so.

Additionally, Rule 10b5-1 contains many other requirements with respect to the adoption and subsequent administration of the Rule 10b5-1 Plan throughout its duration. A Covered Person may not have multiple Rule 10b5-1 Plans in place that cover the same period of time, except under certain conditions specified in Rule 10b5-1 or entered into prior to the adoption of this Policy. Such plans must also include a mandatory cooling-off period before trading can commence for Covered Persons that are directors or officers of the Company that expires on the later of (i) 90 days following such plan adoption or modification or (ii) two business days following the disclosure of S&T's financial results in a Form 10–Q or Form 10–K for the completed fiscal quarter in which the plan was adopted or modified (but not to exceed 120 days following the adoption or modification of the plan). The plans must also include a mandatory cooling-off period before trading can commence of 30 days for persons other than the Company's officers and directors. Additionally, Rule 10b5-1 limits the ability to rely on the affirmative defense for a single-trade plan to one single-trade plan per twelve-month period for all persons other than issuers.

Covered Persons must make their own arrangements with brokers to establish a Rule10b5-1 Plan. However, the adoption of any Rule 10b5-1 Plan providing for transactions in S&T securities (including without limitation, acquisitions and dispositions of common stock,) must be precleared by the CFO, or in his or her absence the CEO, to confirm the absence of Inside Information at the time of such adoption. In addition, any proposed amendment to, alteration of or deviation from an established Rule 10b5-1 Plan will be treated as the adoption of a new Rule 10b5-1 Plan, which must be precleared by the CFO or CEO, as applicable. The CFO or CEO, as

applicable, will not otherwise advise as to the conformity of the Rule 10b5-1 Plan or its execution to the requirements of Rule 10b5-1, which is solely the responsibility of the Covered Person.

In connection with this preclearance, the Covered Person must provide a copy of the proposed Rule 10b5-1 Plan to the CFO or CEO, as applicable, as well as the Covered Person's representation certifying that, on the date of the adoption or modification of the plan: (i) the Covered Person is not aware of any Inside Information about the S&T's securities or S&T; (ii) the Covered Person is adopting Rule 10b5-1 Plan in good faith and not as part of a plan or scheme to evade the prohibitions of Rule 10b-5 under the Securities Exchange Act of 1934, as amended, and (iii) the Covered Person will act in good faith with respect to Rule 10b5-1 Plan throughout the duration of the plan.

The Company must disclose quarterly in its Form 10-Qs and Form 10-Ks whether any director or officer has adopted or terminated any Rule 10b5-1 Plan and the material terms of the Rule 10b5-1 Plan. The Company will use the information provided during the preclearance process and subsequent confirmation by the Covered Person that the Rule 10b5-1 Plan has been adopted, to accumulate the information required for these disclosures.

Additionally, no Covered Person may enter into or adopt a Rule 10b5-1 Plan during the period beginning on the fifteenth day of the third month of the quarter and ending two full trading days after the public release of S&T's quarterly earnings for such fiscal quarter (or the fiscal year in the case of the fourth fiscal quarter).

In addition to the blackout period for entering into a Rule 10b5-1 Plan discussed above, a Rule 10b5-1 Plan must be adopted when the Covered Person is not aware of any Inside Information.

**VII.NON-RULE 10b5-1 TRADING ARRANGEMENTS**

The Company must also disclose quarterly in its Forms 10-Q and10-K whether any director or officer has adopted or terminated any other written trading arrangement that meets the requirements of a "non-Rule 10b5-1 trading arrangement" the material terms of the non-Rule 10b5-1 trading arrangement.

A "non-Rule 10b5-1 trading arrangement" is defined as an arrangement where a director or officer asserts that: (i) at a time when they were not aware of Inside Information about the security or S&T, they adopted a written arrangement for trading the securities; and (ii) the trading arrangement: (a) specified the amount of securities to be purchased or sold and the price at which and the date on which the securities were to be subsequently purchased or sold; (b) included a written formula/algorithm for determining the amount of securities to be purchased or sold and the price at which the securities were to be purchased or sold; or (c) did not permit the covered person to exercise any subsequent influence over how, when, or whether to effect purchases or sales (and any other person who, pursuant to the trading arrangement did exercise such influence must not have been aware of Inside Information when doing so). These types of arrangements are similar to, but do not meet all of the requirements of a Rule 10b5-1 Plan.

**<u>ISSUING DEPARTMENT</u>**<u>: Executive Page 6 of 12</u>

Therefore, in addition to the requirements set forth in Section VI regarding preclearance of Rule 10b5-1 Plans and the trading preclearance requirements set forth in Section X , the adoption of any other arrangement that constitutes a non-Rule 10b5-1 trading arrangement for transactions in S&T securities must be precleared by the CFO, or in his or her absence the CEO. The Company will use the information provided during the preclearance process and subsequent confirmation by the Covered Person that the non-Rule 10b5-1 trading arrangement has been adopted, to accumulate the information required for these disclosures.

**VIII.<u>Employee, Officer and Director Hedging</u>**

Directors, officers, and employees are prohibited from engaging in any hedging transactions (including transactions involving options, puts, calls, prepaid variable forward contracts, equity swaps, collars and exchange funds, or other derivatives) that are designed to hedge or speculate on any change in the market value of S&T's securities.

**IX.<u>COMPLIANCE WITH POLICY</u>**

In order to ensure that all individuals subject to this Policy are aware of and comply with it, S&T will require annual certifications regarding the receipt and understanding of, and agreement to comply with, this Policy.

S&T will investigate any circumstances that come to its attention indicating that anyone subject to this Policy has engaged, or is likely to engage, in conduct that violates the policies and procedures set forth herein. Any violation of this Policy shall be immediately reported to the General Counsel.

Legal penalties for trading on or communicating Inside Information can be severe, both for individuals involved in such unlawful conduct and for their employers and supervisors, and may extend significantly beyond any profits made or losses avoided, including jail terms, criminal fines, civil penalties and civil enforcement injunctions. Given the severity of the potential penalties and the priority given to enforcement, compliance with this Policy is absolutely mandatory. This means that an individual may have to forego a proposed transaction in S&T securities even if he or she planned to make the transaction before learning of the Inside Information and even though he or she may suffer an economic loss or forego anticipated profit by waiting.

ANY TRANSACTIONS, OR "TIPS" IN CONTRAVENTION OF THIS POLICY WILL BE THE SUBJECT OF DISCIPLINARY ACTION WHICH COULD INCLUDE TERMINATION OF EMPLOYMENT AND MAY ALSO SUBJECT THE INDIVIDUAL TO CIVIL OR CRIMINAL SANCTIONS.

This Policy does not provide an exhaustive list of Inside Information or the appropriate procedures in every circumstance for safeguarding nonpublic information or avoiding violation of insider trading laws. Individuals should consult the CFO or CEO when in any doubt. Any questions with respect to the applicability of this Policy to any information or transaction

should be discussed before and not after any action. Regardless of any guidance you receive, you will bear the consequences of any legal or policy violations. Furthermore, the CFO's or CEO's failure to raise an objection to a transaction will not constitute a recommendation by S&T or any of its directors, officers or employees that you engage in that transaction.

**X.<u>PERSONAL SECURITIES TRANSACTIONS BY COVERED PERSONS</u>**

The Company, as a possible "controlling person," under the securities laws, has adopted policies and procedures reasonably designed to prevent unlawful insider trading. To provide assistance in preventing inadvertent violations of applicable securities laws in connection with the purchase and sale of S&T securities, the Company will designate those individuals who may have access to Inside Information ("Covered Persons"). Covered Persons shall include directors, director emeriti, any S&T employee with the title of Executive Vice President or above, all employees in the Accounting, Finance, Legal and Executive Administration Departments, family members, others living in the same household, any other person or entity whose securities trading decisions are influenced or controlled by any of the foregoing, and any other employee designated from time to time as a Covered Person by the CFO or CEO . Except for transactions executed pursuant to a Rule 10b5-1 Plan as discussed in Section VI above, S&T has adopted the following procedures for personal securities transactions by Covered Persons:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.No Covered Person may purchase or sell any security of any other issuer about which he or she possesses Inside Information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.All transactions (including without limitation, acquisitions and dispositions of common stock by purchase, sale or gift, and transactions in employee benefit plans including those discussed in number 3 below) in S&T securities by Covered Persons must be approved in advance by the CFO or, in his or her absence the CEO. A Covered Person must submit a Request for Approval to Trade (a copy of which is attached) certifying that he or she has read this Policy and is not in possession of Inside Information. The CFO may conduct such internal due diligence as he or she deems appropriate under the circumstances. The CFO will notify a Covered Person whether he or she may trade. Approvals will be effective for only two business days from the receipt of pre-clearance unless an exception is granted or the Covered Person becomes aware of Inside Information before the trade is executed in which case the preclearance is void and the trade must not be completed. If the transaction is not completed within the two business days, and nothing has changed with respect to the details of the transaction other than the anticipated timing, a Covered Person may submit an extension request by email to the CFO or, in his absence the CEO, to cover an additional two business days. Approval by the CFO or CEO, as applicable, of any transaction does not constitute legal advice, nor is it a guarantee that a transaction will not be subject to later challenge by a third party.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.Prior approval of any transfers of investment funds by Covered Persons into or out of the S&T Bancorp, Inc. Stock Fund maintained under the Thrift Plan for Employees of S&T Bank (the "Plan") is required in accordance with the procedures discussed in number 2

**DATE ISSUED/REVISED**: 7/30/2025

above. Approval should be requested when a Covered Person submits a Request for Transfer Between Investment Funds to the Plan Administrator. This requirement does not apply to automatic acquisitions of Company common stock under the Plan resulting from prior investment elections.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.The directors, director emeriti, any S&T employee with the title of Executive Vice President or above, all employees in the Accounting, Finance and Executive Administration Departments, and any other employee designated from time to time as a Covered Person by the CFO or CEO, are each responsible for the compliance with these rules by his or her family members, others living in the same household, any other person or entity whose securities trading decisions are influenced or controlled by any of the foregoing and must report or seek approval of their personal securities transactions, as appropriate, as if such transactions were for his or her own account. This Policy does not, however, apply to personal securities transactions of family members, others living in the same household, any other person or entity whose securities trading decisions are influenced or controlled by any of the foregoing where the purchase or sale decision is made by a third party not controlled by or related to the Covered Person.

Covered Persons who are subject to Section 16 of the Securities Exchange Act of 1934, as amended, including (those directors, directors' emeriti and executive officers of the Company who have filed a Form 3 and are required to file a Form 4 and a Form 5, collectively "Section 16 Covered Persons") are reminded of their reporting obligations and possible liability to the Company for "short-swing profits" for transactions in S&T stock. Section 16 Covered Persons may remain subject to the provisions of Section 16 of the Securities Exchange Act of 1934, as amended on a limited basis for up to six months following termination. If a Section 16 Covered Person engages in a transaction in S&T stock prior to termination that did not qualify for an exemption from Section 16(b), the Section 16 Covered Person will remain subject to Section 16 for six months from the date of that transaction For example, if a Section 16 Covered Person engaged in an open market purchase of S&T stock on the last day of employment, any open market or other non-exempt sale of S&T stock occurring within less than six months of that purchase would be subject to Section 16, even though the Section 16 Covered Person is not employed when the opposite way transaction occurred. The Section 16 Covered Person would be required to report the sale on Form 4 within two business days. In addition, the sale could be matched under Section 16(b) with the pre-termination purchase, allowing the Company to recover any resulting short-swing profit. Therefore, following termination, a Section 16 Covered Person should refrain from engaging in any opposite way transactions that occurs within six-months of a non-exempt transaction consummated prior to termination.

In addition, Covered Persons who are directors or the Company officers covered under Corporate Policy #614 – Employee Stock Ownership must comply with stock ownership requirements and/or guidelines approved by the S&T Board of Directors, with exceptions thereto subject to the discretion of the Company Board of Directors as to directors or directors emeriti, while exceptions for officers shall be subject to the discretion of the Compensation and Benefits Committee.

**XI.<u>BLACKOUT PERIODS</u>**

S&T has established four routine quarterly blackout periods ("Quarterly Blackout Periods"). Each Quarterly Blackout Period begins on the fifteenth day of the third month of the quarter and ends two full trading days after the public release of S&T's quarterly earnings for such fiscal quarter (or the fiscal year in the case of the fourth fiscal quarter). In addition to the Quarterly Blackout Periods, S&T may, from time to time, impose other blackout periods on persons who are affected (together with the Quarterly Blackout Periods, referred to as "Blackout Periods"). Trading in S&T securities by Covered Persons is prohibited during S&T's Blackout Periods.

The following transactions are prohibited during a Blackout Period:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Open market purchase or sale of S&T securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Purchase or sale of S&T securities through a broker.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Switching existing balances into or out of the S&T stock fund in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• New cash investments in the dividend reinvestment plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Transfers of S&T securities to or from a trust.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Gifts of S&T securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The following transactions are allowed during a Blackout Period:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The vesting of restricted shares where S&T stock is withheld to satisfy the tax obligation.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Regular and matching contributions to the S&T stock fund in the Plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Regular reinvestment in the dividend reinvestment plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Transactions under a valid Rule 10b5-1 discussed in Section VI above.

The Quarterly Blackout Periods apply, whether or not a reminder notice of the blackout is sent.

Remember that Covered Persons remain subject to the insider trading laws at all times and, accordingly, Covered Persons are prohibited from engaging in transactions even when no Blackout Period is in place if the Covered Person is aware of any Inside Information about S&T.

**XII.<u>STOP-TRANSFER INSTRUCTIONS</u>**

The Company may, in its discretion, provide stop transfer instructions to its transfer agent in order to enforce trading restrictions imposed by this Policy, including, without limitation, restrictions relating to blackout periods or post-termination transactions.

**Audit & Advisory Services**
