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.

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 real estate values, particularly with respect to our commercial real estate, or CRE, and mortgage activities, could adversely affect the value of property used as collateral for our loans and 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, 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. This could result in higher charge-offs which could have a material adverse effect on our operating results and financial condition.

Changes in the overall credit quality of our portfolio can have a significant impact on our earnings.

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 ACL through undergoing a periodic review of the loan portfolio, where it considers historical losses, the national unemployment forecast produced by the Federal Reserve combined with 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 allowances 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. Incorrect assumptions could lead to material underestimates of expected losses and an inadequate ACL. As our assessment of expected losses changes, we may need to increase or decrease our ACL, which could significantly impact our financial results and profitability.

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.

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 commercial and industrial, or C&I, 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.

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, which has increased to levels not experienced in years, 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. If the macroeconomic environment worsens, our credit portfolio and allowance for credit losses 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.

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 and further adverse developments affecting the financial services industry, and the soundness of financial institutions, and further disruption to the economy and 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 recent events, we face the potential for reputational 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 (FHLB), our efforts to monitor and manage liquidity risk may not be successful or sufficient to deal with dramatic or unanticipated increase 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.

Additionally, regulatory pressures and additional regulation of financial institutions as a result of the industry developments could have material adverse effects on our business, results of operations, financial condition and growth prospects.

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

In late February 2022, Russia launched a large-scale military attack on Ukraine. In response to the military action by Russia, government actions, including broad-ranging economic sanctions against Russia, have been taken by the United States, the United Kingdom, the European Union and other countries. The U.S. and global markets have experienced volatility and disruption as a result of this military conflict and imposition of sanctions, impacting the financial and commodities markets. The continued impact on financial markets, including the level and volatility of interest rates, could impact our earnings. Russian military actions and the resulting sanctions could further adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets. In addition, Russia may take retaliatory actions and other counter measures including cyberattacks against the U.S., its government, infrastructure and businesses, including S&T.

Additionally, an armed conflict began in October 2023 involving Hamas and Israel. This conflict, as well as further escalation of tensions between Israel and various countries in the Middle East and North Africa may cause additional detrimental effects on the global economy, including capital markets.

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 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. 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 efficiencies within our operations. Many of our large competitors have substantially greater resources to invest in technological improvements. We may not be able to effectively implement new technology-driven products 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 could have a material adverse impact on our business, financial condition and results of operations.

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 reputational harm.

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. Cyber security 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.

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 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 cyber security breaches affecting debit accounts of their customers. We have experienced cyber security 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. 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. Additionally, a number of our employees have shifted to working from remote locations, which we expect to remain high for the foreseeable future, increasing the number of surfaces that require protection and the overall risks and exposures to cyber threats.

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.

As cyber threats continue to evolve, we may be required to expend significant additional resources to continue to modify and enhance our protective measures or to investigate and remediate any information security vulnerabilities or incidents. Any of these matters could result in our loss of customers and business opportunities, significant disruption to our operations and business, 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, 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, reputational damage, reimbursement or other compensatory costs, and additional compliance costs. In addition, any of the matters described above could adversely impact our results of operations and financial condition.

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 reputation 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. 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 operation, financial condition or stock price. Furthermore, fraudulent activity could negatively impact our brand and reputation, which could also adversely affect our results of operation, financial condition or stock price. Fraudulent activity could also lead to regulatory intervention or regulatory sanctions.

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 reputation, loss of business, remedial costs, additional regulatory scrutiny or exposure to civil litigation and possible financial liability. 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 operation.

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, 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.

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.

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 harmed.

Declines in the value of investment securities held by us could require write-downs, which would reduce our earnings.

In order to diversify earnings and enhance liquidity, we own debt instruments of government agencies and 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.

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. The regulatory environment of the current administration may take a more active approach to financial services regulation with respect to its major policy goals, such as climate change, racial equity, and consumer protection. 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 reputation. The ramifications and uncertainties of the level of government intervention in the U.S. financial system could also adversely affect us.

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. 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.

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 reputation, 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 reputation and adversely impact our earnings and liquidity.

Reputational risk, or 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, litigation, ethical issues or inadequate protection of customer information. Financial companies are highly vulnerable to reputational 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 reputation. We expend significant resources to comply with regulatory requirements, and the failure to comply with such regulations could result in reputational harm or significant legal or remedial costs. Damage to our reputation could adversely affect our ability to retain and attract new customers and employees, expose us to litigation and regulatory action and adversely impact our earnings 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.

We are subject to remaining uncertainty associated with the transition away from LIBOR.

Following publication on June 30, 2023, no settings of the London Interbank Offered Rate (“LIBOR”) continue to be published on a representative basis and publication of many non-U.S. dollar LIBOR settings has been entirely discontinued. We had a significant number of loans, derivative contracts, borrowings and other financial instruments with attributes that were either directly or indirectly dependent on LIBOR. While we believe that we have successfully managed our transition from LIBOR to alternative reference rates, given the inherent difference between LIBOR and the alternative reference rates, there remain some uncertainties regarding the transition from LIBOR. In addition, due in part to the limited history of the alternative reference rates, and continued uncertainty regarding their future performance, the impact on interest income and expense, the return on and market value of assets and the impact on certain derivative financial instruments may vary from expectations. While we do not expect the transition from LIBOR and the risks related thereto to have a material adverse effect on us, there remains some uncertainty as to the ultimate impact on our business and results of operations.

Our business could be negatively impacted by environmental, social and governance (ESG) matters, including climate change and related legislative and regulatory initiatives.

There has been an increased focus from regulators, investors, customers, employees and other stakeholders concerning environmental, social and governance, or ESG, practices and disclosure, including climate change, hiring practices, the diversity of the work force, racial and social justice issues and shareholder rights.

With respect to environmental in particular, increased focus and concern over the effects of climate change have resulted in increased political and social initiatives directed toward climate change. Governments have entered into international agreements with respect to climate change, and U.S. federal and state legislatures, regulatory agencies, and supervisory authorities, including those with oversight of financial institutions, have proposed initiatives seeking to mitigate the effects of climate change. While many of the current regulatory proposals do not apply directly to S&T, continued focus on climate change may lead to the promulgation of new regulations or supervisory guidance applicable to S&T and, as a result, we may experience increased compliance costs and other compliance-related risks. Furthermore, our customers could be impacted by regulatory initiatives focused on addressing and mitigating the effects of climate change resulting in an adverse impact on their financial condition and creditworthiness. Depending on the nature of the initiative, the business impacted, and the composition of loan portfolio, our business and results of operations could be negatively impacted by climate change initiatives directed at our customers. Additionally, our business and the business of our customers could be negatively impacted by disruptions in economic activity resulting from the physical impacts of climate change.

Furthermore, new government regulations with respect to other ESG matters could also result in new or more stringent forms of ESG oversight and expanded mandatory and voluntary reporting, diligence, disclosure and ESG-related compliance costs. In addition, we could be criticized for the scope of such initiatives or goals or perceived as not acting responsibly in connection with these matters. Failure to adapt to or comply with regulatory requirements or investor or stakeholder expectations and standards with respect to ESG matters could have a material adverse impact on our future results of operations, financial position, cash flows, ability to do business with certain third parties and our stock price.

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 reputation 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. 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 at the Federal Home Loan Bank of Pittsburgh, or FHLB, federal funds lines with other financial institutions, the Federal Reserve Borrower-in-Custody Program and the Federal Reserve Bank Term Funding Program, or BTFP.

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 and other short-term

funding sources, including the Federal Reserve Discount Window and brokered deposits.

We own stock in the Federal Home Loan Bank of Pittsburgh, or FHLB, in order to qualify for membership in the FHLB system, which enables us to borrow on our line of credit with the FHLB 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, as well as the Federal Reserve BTFP which is available to us through March 11, 2024 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:

•volatility of stock market prices and volumes in general;

•changes in market valuations of similar companies;

•the nature and composition of our ownership base;

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

•the flow of capital among market sectors;

•changes in the conditions of credit markets;

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

•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;

•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 Board;

•additions or departures of key members of management;

•fluctuations in our quarterly or annual operating results; and

•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 reputational 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:

a.Protecting data through the use of automated and manual processes;

b.Periodically assessing and updating the program to address an evolving threat environment;

c.Maintaining a team of IT security professionals that continually monitor, detect, analyze, investigate and report cybersecurity threats; and

d.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:

a.Identifying reasonably foreseeable internal and external threats that could result in a cybersecurity incident;

b.Assessing the likelihood and potential impact of those threats; and

c.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 FFEIC 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, reputational impact, 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 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, 2023, 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, CSO, Chief Information and Technology Officer 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.

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

Stock Prices and Dividend 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 January 31, 2024, we had approximately 2,539 shareholders of record. The number of record-holders does not reflect the number of persons or entities holding stock in nominee name through banks, brokerage firms and other nominees.

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 $0.33 per share on January 24, 2024.

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

The following table is a summary of our purchases of common stock during the fourth quarter of 2023:

(1) On January 25, 2023, our Board of Directors authorized an extension of its $50 million share repurchase plan, which was set to expire March 31, 2023. This authorization extended the expiration date of the repurchase plan through March 31, 2024. The plan permitted S&T to repurchase shares up to the previously authorized $50 million in aggregate value of S&T's common stock through a combination of open market and privately negotiated repurchases. On January 24, 2024, our Board of Directors authorized a new $50 million share repurchase plan.The new plan replaced the existing share repurchase plan effective immediately and is set to expire May 30, 2025. 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.

(2)Includes excise tax on repurchases, net of issuances for restricted stock awards.

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. The Company's discussion and analysis focuses on significant factors impacting the financial condition and results of operations for the year ended December 31, 2023 as compared to the year ended December 31, 2022. This discussion and analysis should be read in conjunction with our Consolidated Financial Statements and Supplementary Data and related notes within this Annual Report on Form 10-K. A similar discussion and analysis that compares the year ended December 31, 2022 to the year ended December 31, 2021 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, 2022, filed with the Securities and Exchange Commission, or SEC, on February 24, 2023. Certain reclassifications have been made to prior periods to place them on a basis comparable with 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; cyber-security concerns; rapid technological developments and changes; operational risks or risk management failures by us or critical third parties, including fraud risk; our ability to manage our reputational risks; sensitivity to the interest rate environment, 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; any remaining uncertainties with the transition from LIBOR as a reference rate; regulatory supervision and oversight, including changes in regulatory capital requirements and our ability to address those requirements; unanticipated changes in our liquidity position; unanticipated changes in regulatory and governmental policies impacting interest rates and financial markets; changes in accounting policies, practices or guidance; legislation affecting the financial services industry as a whole, and S&T, in particular; 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 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.

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 and other intangible assets 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 2023. 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 70 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 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.

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

27

Table of Contents

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, 2023, we concluded that goodwill is not impaired.

Recent Accounting Pronouncements and Developments

Note 1 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 discussed below. We believe these non-GAAP financial measures provide information useful to investors in understanding our underlying business, operational performance and performance trends as they facilitate comparisons with the performance of other companies in the financial services industry. Although we believe that these non-GAAP financial measures enhance investors’ understanding of our business and performance, these non-GAAP financial measures should not be considered alternatives to GAAP or considered to be more important than financial results determined in accordance with GAAP, nor are they necessarily comparable with non-GAAP measures which may be presented by other companies.

The interest income on interest-earning assets, net interest income and net interest margin are presented on an FTE basis (non-GAAP). The FTE basis (non-GAAP) adjusts for the tax benefit of income on certain tax-exempt loans and securities and the dividend-received deduction for equity securities using the federal statutory tax rate of 21 percent for each period. We believe this to be the preferred industry measurement of net interest income that provides a relevant comparison between taxable and non-taxable sources of interest income.

The following table reconciles interest and dividend income and net interest income per the 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:

Years ended December 31,

Plus: taxable equivalent adjustment 0.03 % 0.02 % 0.03 %

The efficiency ratio is noninterest expense divided by noninterest income plus 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. Below is a reconciliation of the non-GAAP efficiency ratio.

Earnings per share - diluted $ 3.74 $ 3.46 $ 2.81

Return on average shareholders' equity 11.80 % 11.47 % 9.30 %

We earned record net income of $144.8 million for the second consecutive year, representing an increase of $9.3 million or 6.83 percent, compared to net income of $135.5 million in 2022. Earnings per diluted share increased 8.1 percent to a record $3.74 in 2023 compared to $3.46 in 2022. The increase in net income was primarily due to higher net interest income related to higher interest rates. Return on average assets increased 8 basis points to 1.56 percent for 2023 compared to 1.48 percent for 2022. Return on average shareholders' equity increased 33 basis points to 11.80 percent for 2023 compared to 11.47 percent for 2022.

Net interest income increased $33.6 million, or 10.65 percent, to $349.4 million compared to $315.8 million in 2022. Interest and dividend income increased $137.2 million and interest expense increased $103.5 million compared to 2022. The net interest margin, or NIM, on an FTE basis (non-GAAP) increased 37 basis points to 4.13 percent compared to 3.76 percent in 2022. The increases in net interest income and NIM on an FTE basis (non-GAAP) were primarily due to higher interest rates during 2023 and an asset sensitive balance sheet. 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 $9.5 million to $17.9 million for 2023 compared to $8.4 million for 2022. The increase in the provision for credit losses was mainly due to an increase in net charge-offs in 2023 and our qualitative reserve. Net loan charge-offs were $13.2 million, or 0.18 percent of average loans, in 2023 compared to $2.6 million, or 0.04 percent of average loans, in 2022.

Noninterest income was relatively consistent at $57.6 million compared to $58.3 million in 2022. Mortgage banking income decreased $1.1 million due to a decline in loan sale activity caused by rising interest rates and a shift to holding originated mortgage loans on the balance sheet. Various other customer fees were down compared to the prior year due to lower activity. Offsetting these decreases was an increase of $2.5 million in other noninterest income primarily related to valuation adjustments and a $0.8 million increase in net gain on the sale of OREO partially offset by a $0.8 million decrease in fees on commercial loan swaps.

Noninterest expense increased $13.6 million to $210.3 million compared to $196.7 million in 2022. Salaries and employee benefits increased $8.2 million primarily due to higher salaries related to inflationary wage pressure, the acquisition of new talent and a change in the valuation adjustment on a nonqualified benefit plan. Loan-related expense increased $2.1 million primarily due to an increase in loan collection and legal expenses for the workout of criticized and classified loans. Furniture, equipment and software expense increased $1.3 million due to new software implemented in 2023. FDIC insurance increased $1.3 million due to a two basis point increase in the assessment rate. The efficiency ratio (non-GAAP) for 2023 improved to 51.35 percent compared to 52.34 percent for 2022 due to higher revenue in 2023. 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 increased $0.6 million to $34.0 million in 2023 compared to $33.4 million in 2022. The increase in our income tax provision was primarily due to a $9.9 million increase in pretax income in 2023 compared to 2022. The effective tax rate decreased 0.8 percent to 19.0 percent in 2023 compared to 19.8 percent in 2022. The decrease in the effective tax rate was primarily due to an increase in Low Income Housing Tax Credits, or LIHTCs, in 2023 compared to 2022.

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 original maturities ranging from three to five years. There were no new interest rates swaps entered into in 2023. 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 have increased substantially in 2022 and 2023 resulting in an unrealized loss on the cash flow hedges of $11.6 million, which is reported in Other Comprehensive Income (Loss), or OCI, net of applicable taxes.

increased interest rates. Overall, the FTE rate (non-GAAP) on interest-earning assets increased 158 basis points compared to 2022.

Interest expense increased $103.5 million compared to 2022. The increase in interest expense was primarily due to higher interest rates and a shift in our funding mix to higher cost certificates of deposits and borrowings. Average interest-bearing deposits decreased $98.0 million compared to 2022 due to the competitive market driven by rising interest rates. The average rate paid on interest-bearing deposits increased 152 basis points due to higher interest rates. Certificates of deposit increased $308.8 million compared to 2022. The increase in certificates of deposits was primarily due to higher interest rates resulting in customers moving deposits to higher yield accounts. Average borrowings increased $435.0 million compared to 2022 primarily due to decreased deposit balances and increased loans. The average rate paid on borrowings increased 258 basis points compared to 2022 due to higher interest rates. Overall, the cost of interest-bearing liabilities increased 185 basis points compared to 2022.

Provision for Credit Losses

The provision for credit losses includes a provision for losses on loans and on unfunded commitments. The provision for credit losses fluctuates based on changes in loan balances, risk ratings, net loan charge-offs/recoveries, the macro environment and our Current Expected Credit Loss, or CECL, forecast. The provision for credit losses increased $9.5 million to $17.9 million for 2023 compared to $8.4 million for 2022. The provision for credit losses included a reduction of $1.4 million for the reserve for unfunded commitments for 2023 compared to an increase of $3.0 million for 2022.

The increase in the provision for credit losses for 2023 compared to 2022 was primarily due to increases in net loan charge-offs and our qualitative reserve. Net loan charge-offs for 2023 were $13.2 million, or 0.18 percent of average loans, compared to $2.6 million, or 0.04 percent of average loans for 2022. Offsetting loan charge-offs during 2023 were $11.5 million of loan recoveries which included a $9.3 million recovery related to a 2020 customer fraud compared to $9.0 million of loan recoveries during 2022. The increase in qualitative reserve was primarily due to deterioration in the CRE Price Index and our qualitative reserve capturing additional expected losses in commercial loans that are not included in the model. Offsetting the increase in provision for credit losses during 2023 was a $4.4 million decrease in the provision for unfunded loan commitments primarily due to a decrease in loss rates and unused commitments in the construction portfolio.

Noninterest income decreased $0.6 million to $57.6 million compared to $58.2 million in 2022. Mortgage banking income decreased $1.1 million due to a decline in loan sale activity caused by rising interest rates and a shift to holding originated mortgage loans on the balance sheet. Debit and credit card income decreased by $0.8 million due to decreased customer activity. Service charges on deposit accounts decreased by $0.6 million due to decreases in returned check and the elimination of non-sufficient funds, or NSF, fees. Other noninterest income increased $2.5 million primarily related to a $3.3 million increase in the fair value of assets in a nonqualified benefit plan, which has a corresponding offset in salaries and benefits resulting in no impact to net income, and an increase in net gain on the sale of OREO of $0.8 million, partially offset by a $0.7 million decrease in the valuation of our commercial loan swaps and a $0.8 million decrease in fees on our commercial loan swaps.

medical costs and an increase in the fair value of assets in a nonqualified benefit plan, partially offset by a decrease in incentives. Loan-related expense increased $2.1 million primarily due to an increase in loan collection and legal expenses for the workout of criticized and classified loans. Furniture, equipment and software expense increased $1.3 million mainly due to new software implemented in 2023. FDIC insurance increased $1.3 million due to a two basis point increase in the assessment rate.

Provision for Income Taxes

The provision for income taxes increased $0.6 million to $34.0 million in 2023 compared to $33.4 million for 2022. The increase in our income tax provision was primarily due to a $9.9 million increase in income before taxes in 2023 compared to 2022.

The effective tax rate, which is total tax expense as a percentage of income before taxes, decreased to 19.0 percent in 2023 compared to 19.8 percent in 2022. The decrease in the effective tax rate was primarily due to an increase in LIHTCs in 2023 compared to 2022. 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 LIHTCs.

Financial Condition as of December 31, 2023

Total assets increased $441.0 million to $9.6 billion at December 31, 2023 compared to $9.1 billion at December 31, 2022. Total portfolio loans increased $469.4 million to $7.7 billion at December 31, 2023 compared to $7.2 billion at December 31, 2022. The increase in loans is primarily related to consumer loan growth of $352.9 million with an increase in consumer real estate of $362.9 million compared to December 31, 2022. The commercial loan portfolio increased $116.5 million at December 31, 2023 compared to December 31, 2022 due to an increase of $229.4 million in CRE loans offset by decreases of $76.9 million in C&I and $36.1 million in construction.

Securities remained relatively unchanged at $970.4 million at December 31, 2023 compared to $1.0 billion at December 31, 2022. The bond portfolio was in a net unrealized loss position of $82.0 million at December 31, 2023 compared to a net unrealized loss position of $102.3 million at December 31, 2022. The decrease in the net unrealized loss portion of the bond portfolio of $20.3 million was due to a change in interest rates.

Our deposits increased $301.8 million to $7.5 billion at December 31, 2023 compared to $7.2 billion at December 31, 2022. The increase related to the addition of $375.7 million of brokered deposits, including $200.7 million of brokered money market accounts and $175.0 million of brokered certificates of deposit. Customer deposits decreased $73.9 million compared to the prior year with decreases in noninterest-bearing demand deposits of $366.8 million and savings of $168.0 million partially offset by an increase in certificates of deposit of $472.1 million. Customer deposits decreased primarily due to lower commercial and consumer deposits due to the competitive pricing in this higher interest rate environment. Additionally, noninterest-bearing demand decreased due to the shift into interest-bearing deposits as a result of the elevated interest rate environment.

Total borrowings increased $64.4 million to $503.6 million at December 31, 2023 compared to $439.2 million at December 31, 2022 primarily due to loan growth.

Total shareholders’ equity increased by $98.8 million to $1.3 billion at December 31, 2023 compared to $1.2 billion at December 31, 2022. The increase was primarily due to net income of $144.8 million and other comprehensive income of $21.2 million, offset by dividends of $49.9 million and common stock repurchases of $20.0 million.

Securities Activity

The balances and average rates of our securities portfolio are presented below as of December 31:

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 securities portfolio represents 10.2 percent of total assets and is classified as available for sale.The portfolio primarily consists of structured agency backed fixed income securities with limited credit exposure. Securities decreased $32.4 million to $970.4 million at December 31, 2023 compared to $1.0 billion at December 31, 2022.

At December 31, 2023, our bond portfolio was in a net unrealized loss position of $82.0 million compared to a net unrealized loss position of $102.3 million at December 31, 2022. At December 31, 2023, our bond portfolio had gross unrealized losses of $83.8 million offset by $1.8 million in gross unrealized gains, compared to December 31, 2022, when total gross unrealized losses were $102.6 million offset by gross unrealized gains of $0.3 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, 2023 or December 31, 2022. 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, 2023. 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 2023, 2022 or 2021. The securities portfolio could generate impairments in future periods requiring realized losses to be reported.

Lending Activity

The following table summarizes our loan portfolio as of December 31:

Commercial

Consumer

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 maintain a General Lending Policy to control 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 70.1 percent of total portfolio loans at December 31, 2023 compared to 73.0 percent at December 31, 2022. Within our commercial portfolio, the CRE and commercial construction portfolios combined comprised $3.7 billion, or 69.4 percent, of total commercial loans and 48.6 percent of total portfolio loans at December 31, 2023 compared to $3.5 billion, or 67.2 percent, of total commercial loans and 49.1 percent of total portfolio loans at December 31, 2022.

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

Our multi-family and office segments are the most significant CRE and commercial construction concentrations for us. The multi-family segment was $658.9 million, or 8.6 percent of total portfolio loans at December 31, 2023 compared to $568.3 million, or 7.9 percent at December 31, 2022. Criticized and classified loans in the multi-family segment are minimal at only $7.4 million at December 31, 2023. The office segment represents $516.5 million, or 6.7 percent of total portfolio loans at December 31, 2023 compared to $511.8 million, or 7.1 percent at December 31, 2022. Criticized and classified loans in the office segment were only $11.6 million at December 31, 2023. Approximately 85 percent of the office portfolio is located in non central business districts, or CBD, with the remaining 15 percent in CBD within our direct markets. We completed a target review of the office portfolio in the third quarter of 2023 and did not identify any material credit risk.

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 this geography of 3.9 percent of the combined portfolios and 1.9 percent of total portfolio loans at December 31, 2023. This compares to 5.8 percent of the combined portfolios and 2.9 percent of total portfolio loans at December 31, 2022.

Total portfolio loans increased $469.4 million, or 6.5 percent, to $7.7 billion at December 31, 2023 compared to $7.2 billion at December 31, 2022. As of December 31, 2023, 65.0 percent of our total loans were variable rate loans and 35.0 percent were fixed rate loans.

Commercial loans increased $116.5 million related to an increase of $229.4 million in CRE offset by decreases of $76.9 million in C&I and $36.1 million in commercial construction compared to December 31, 2022. Our loan demand was influenced by the uncertain macroeconomic environment during 2023.

Consumer loans represent 29.9 percent of our total portfolio loans at December 31, 2023 and 27.0 percent at December 31, 2022. Consumer loans increased $352.9 million compared to December 31, 2022 primarily due to an increase of $343.2 million in the residential real estate portfolio and $19.7 million in consumer construction. Portfolio consumer real estate loans increased in 2023 based on a shift from mortgage loans sold to loans held in the portfolio on our balance sheet due to increased jumbo loans and the pricing of loans in the secondary market compared to December 31, 2022.

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 typically originate and sell loans into the secondary market, primarily to Fannie Mae. We sell these loans 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. During 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 mainly due to loan pricing in the secondary market and the desire to reduce our variable rate loan exposure in this interest rate environment. We continue to monitor this strategy and could shift back to selling more residential mortgages into the secondary market in future periods. We sold $0.2 million of 1-4 family mortgages in 2023 and $28.6 million in 2022 to Fannie Mae. Our servicing portfolio of mortgage loans that we had originated and sold into the secondary market was $707.8 million at December 31, 2023 compared to $772.9 million at December 31, 2022. We also offer a variety of unsecured and secured consumer loan products.

The following table presents the maturity of commercial and consumer loans outstanding as of December 31, 2023:

Maturity

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. 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:

December 31,

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

Credit Quality

On a quarterly basis, a criticized asset meeting is 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 re-evaluation of assets held as collateral.

Additional credit risk management practices include periodic review, at least annually, and updates of our lending policies and procedures to support sound underwriting practices and portfolio management through portfolio stress testing. We have a portfolio monitoring group that performs an annual review of all commercial relationships greater than $1.5 million and a quarterly review of our Watch rated portfolio. Business banking relationships less than $1.5 million are monitored through portfolio management software that identifies credit risk indicators. 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.

Nonperforming assets, or NPAs, consist of nonaccrual loans and OREO. The following represents NPAs as of December 31:

Nonaccrual Loans

Nonaccrual loans as a percent of total loans 0.30 % 0.27 %

Nonperforming assets as a percent of total loans plus OREO 0.30 % 0.31 %

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 due.

Nonperforming assets increased $0.9 million, or 4.1 percent, resulting in a nonperforming assets to total loans plus OREO ratio of 0.30% at December 31, 2023 compared to 0.31% at December 31, 2022. Nonaccrual loans increased $3.9 million, or 20.4 percent, to $22.9 million at December 31, 2023 compared to $19.1 million at December 31, 2022. The decrease in OREO related to the sale of a commercial property that resulted in a gain on sale of OREO of $3.9 million, which is included in other noninterest income.

The following represents delinquency as of December 31:

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. Loans past due 90 days or more increased $3.9 million compared to December 31, 2022 and represented 0.30 percent of total loans at December 31, 2023. Loans past due by 30 to 89 days decreased $5.2 million and represented 0.20 percent of total loans at December 31, 2023.

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

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

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:

•The status of a bankruptcy proceeding;

•The value of collateral and probability of successful liquidation; and/or

•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 is the ACL balance by portfolio segment as of December 31:

(dollars in thousands) Amount % ofTotal Amount % ofTotal

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 $108.0 million, or 1.41 percent of total portfolio loans, at December 31, 2023, compared to $101.3 million, or 1.41 percent of total portfolio loans, at December 31, 2022. The increase in the ACL of $6.7 million was primarily due to a $7.7 million increase in our qualitative reserve mainly related to deterioration in the Commercial Real Estate Price Index and a higher C&I segment specific reserve which captures additional expected losses that are not included in the quantitative model. Our quantitative reserve decreased $1.0 million primarily due to a reduction in criticized and classified loans mainly in our CRE healthcare and CRE hotel portfolios partially offset by higher C&I substandard loans and loan growth during 2023.

Federal Home Loan Bank and Other Restricted Stock

At December 31, 2023, we held FHLB of Pittsburgh stock of $24.0 million compared to $22.0 million at December 31, 2022. 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, 2023. The FHLB exceeds all required capital ratios. Additionally, we considered that the FHLB has been paying dividends and actively redeeming stock throughout 2023 and 2022. Accordingly, we believe sufficient evidence exists to conclude that no impairment existed at December 31, 2023.

Deposits

Deposits are our primary source of funds. We have a well-diversified deposit base with a balance mix of 56.4 percent personal, 34.1 percent business, 4.5 percent public funds and 5.0 percent brokered at December 31, 2023.

The following table presents the composition of deposits at December 31:

Customer deposits

Brokered deposits

Total deposits increased $301.8 million, or 4.18 percent, at December 31, 2023 compared to December 31, 2022. Total customer deposits decreased $73.9 million from December 31, 2022 primarily due to lower commercial and consumer deposits due to the competitive pricing in this higher interest rate environment. Additionally, noninterest-bearing demand decreased due to the shift into interest-bearing deposits as a result of the elevated interest rate environment. Total brokered deposits increased $375.7 million from December 31, 2022. 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 increased $210.4 million to $277.7 million at December 31, 2023 compared to $67.3 million at December 31, 2022.

We have total uninsured deposits of $2.3 billion, or 30.0 percent of our total deposit base, compared to $2.5 billion, or 34.0 percent, at December 31, 2022. Included in uninsured deposits is $296.0 million, or 4.0 percent of our total deposit base, of municipal deposits which are fully collateralized.

The daily average balance of deposits and rates paid on deposits are summarized in the following table for the years ended December 31:

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, remained unchanged at $2.2 billion at December 31, 2023 and December 31, 2022. Assets under administration consisted of $1.0 billion in S&T Trust, $1.0 billion in S&T Financial Services and $0.2 billion in Stewart Capital Advisors.

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. The 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. The ALCO monitors and manages liquidity through various ratios, reviewing cash flow projections, performing stress tests and having a detailed contingency funding plan. The 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, 2023 - 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 Federal Home Loan Bank of Pittsburgh, or FHLB, federal funds lines with other financial institutions and the brokered deposit market. Additionally, S&T has borrowing availability through the Federal Reserve Borrower-in-Custody Program and the Federal Reserve BTFP.

In response to recent bank failures, the Federal Reserve authorized additional funding availability to eligible depository institutions through the BTFP. The program is intended to help assure depositors that their institutions have an additional source of liquidity to meet their needs. Under the BTFP, any collateral eligible for purchase by the Federal Reserve Banks in open market operations can be pledged including U.S. Treasury securities, U.S. Agencies and U.S. Agency mortgage-backed securities. Collateral advances will be equal to 100 percent of the par value of the collateral pledged with a term of up to one year. Interest was charged at a fixed rate equal to the one-year overnight index swap rate plus 10 basis points with no prepayment penalty. The rate on new advances, beginning on January 25, 2024, is set to be no lower than the interest rate on reserve balances in effect on the day the loan is made. As of December 31, 2023, we have $637.0 million of collateral available to pledge under the program and no outstanding balance. The Federal Reserve has announced that it is ending the BTFP and will cease making new loans under this program on March 11, 2024.

Available borrowing capacity exceeds uninsured deposits of $2.3 billion at December 31, 2023 and $2.5 billion at December 31, 2022. The following table summarizes borrowing funding sources available as of the dates presented:

(1) Emergency lending program created by the Federal Reserve in March 2023.

At December 31, 2023, we had available borrowing capacity of $4.1 billion, of which $2.7 billion was remaining borrowing availability with 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.

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, 2023, S&T Bank had $897.4 million in highly liquid assets, which consisted primarily of $160.3 million in interest-bearing deposits with banks and $736.9 million in unpledged securities. This resulted in a highly liquid assets to total assets ratio of 9.4 percent at December 31, 2023 compared to 9.6 percent at December 31, 2022. Highly liquid assets have increased by $27.3 million when comparing December 31, 2023 to December 31, 2022. The majority of the increase in liquid assets is attributed to increases in cash balances. Refer to Note 12. Qualified Affordable Housing, 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 $98.8 million, or 8.3 percent, to $1.3 billion at December 31, 2023 compared to $1.2 billion at December 31, 2022. The increase was primarily due to net income of $144.8 million and other comprehensive income of $21.2 million, partially offset by dividends of $49.9 million and common stock repurchases of $20.0 million. The other comprehensive income was primarily due to a $15.9 million improvement in unrealized losses on our available-for-sale debt securities, net of tax and an improvement of $5.2 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 11.21 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 13.37 percent compared to the regulatory guideline of 6.50 percent to be well-capitalized. Our risk-based Tier 1 and Total capital ratios were 13.69 percent and 15.27 percent, which places us above the federal bank regulatory agencies’ well-capitalized guidelines of 8.00 percent and 10.00 percent, respectively. 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.

In July 2013, the federal banking agencies issued a final rule to implement Basel III and the minimum leverage and risk-based capital requirements of the Dodd-Frank Act. The rule requires a banking organization 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.

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

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, 2023, 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 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 our management committee, 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.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

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

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

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

48

Table of Contents

S&T BANCORP, INC. AND SUBSIDIARIES

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The results from the rate shock analyses on net interest income are 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 rates up scenarios when comparing December 31, 2023 to December 31, 2022 primarily because we have a different deposit mix, more short-term borrowings and a larger fixed-rate loan portfolio. The percentage change in pretax net interest income in the rates down scenario shows an improvement when comparing December 31, 2023 to December 31, 2022 because of our increased ability to cut liability costs as deposit rates have increased and we have more short-term borrowings. The changes in our percentage changes in pretax net interest income reflect our strategic efforts to reduce our exposure to changes in interest rates. Our EVE analyses show a decline in the percentage change in EVE in the rates up scenarios and an improvement in rates down scenarios when comparing December 31, 2023 to December 31, 2022. These changes are mainly the result of the impact of interest rates on the value of nonmaturity deposits and deposit valuation methodology enhancements that recognize changes in customer behavior.

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.

Filing HTML rendered to line-structured narrative text by the shipped reducer (datafeeds.edgar_fulltext.visible_text, keep_table_headers=True): scripts and inline-XBRL headers are dropped, and table content is reduced to its short label cells — numeric table data is not rendered and is therefore not counted. The same rendering is used for every year, so a year-over-year comparison is like for like.

The text is our rendering of the filing, not a facsimile: original pagination, typography and tables are not reproduced, and the numbers live in the financial statements (FA).

The outline locates item HEADINGS in this document. Only Items 1A and 7 have certified boundaries elsewhere in the terminal (the redline and the narrative-overlap number); every span here runs from one heading found to the next heading found.

How the outline was chosen. It is the longest chain of item headings that runs forward through both the document and the standard item order: 22 headings are on that chain and 39 further heading-shaped lines are not — the table-of-contents echo of every item, cross-references and exhibit-list mentions. Each entry's length is measured from its heading to the next heading on the chain.
