NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1. BASIS OF PRESENTATION
Principles of Consolidation
The interim Consolidated Financial Statements include the accounts of S&T Bancorp, Inc., or S&T, and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. Investments of 20 percent to 50 percent of the outstanding common stock of investees are accounted for using the equity method of accounting.
Basis of Presentation
The accompanying unaudited interim Consolidated Financial Statements of S&T have been prepared in accordance with generally accepted accounting principles, or GAAP, in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the Securities and Exchange Commission, or SEC, on February 24, 2023 (2022 Form 10-K). In the opinion of management, the accompanying interim financial information reflects all adjustments, consisting of normal recurring adjustments, necessary to present fairly our financial position and the results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year or any future period.
Reclassification
A mounts in prior period financial statements and footnotes are reclassified whenever necessary to conform to the current period presentation. Reclassifications had no effect on our results of operations or financial condition.
Use of Estimates
The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.
Recently Adopted Accounting Standards Updates, or ASU, or Updated
Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting
In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in this ASU provided optional guidance for a limited period of time to ease the potential burden in accounting for or recognizing the effects of reference rate reform on financial reporting. The amendments provided optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts and other transactions affected by the anticipated transition away from the London Inter-Bank Offered Rate, or LIBOR, toward new interest rate benchmarks. The optional guidance generally allowed for the modified contract to be accounted for as a continuation of the existing contract and does not require contract remeasurement at the modification date or reassessment of a previous accounting determination. The amendments in this ASU were effective as of March 12, 2020 through December 31, 2022. In January 2021, the FASB issued ASU 2021-01, Reference Rate Addendum (Topic 848) which clarified that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The guidance was effective for all entities as of March 12, 2020 through December 31, 2022. In December 2022, the FASB issued ASU No 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848. The amendments in this ASU defer the sunset date for applying the reference rate reform relief by two years to December 31, 2024. We adopted ASU 2020-04 and ASU 2021-01 on January 1, 2022 and ASU 2022-06 upon issuance. We utilized the LIBOR transition relief as contract modifications were made during the course of the reference rate reform transition period. ASU 2020-04, ASU 2021-01 and ASU 2022-06 did not have a material impact on our consolidated financial statements.

Financial Instruments Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures
In March 2022, the FASB issued ASU 2022-02, Financial Instruments Credit Losses (Topic 326): Troubled Debt Restructuring and Vintage Disclosures. The guidance eliminates the “once a TDR, always a TDR” requirement for loan disclosures and requires disclosures about the performance of modified loans to borrowers experiencing financial difficulty in the 12 months following the modification.
The amendments eliminate the recognition and measurement guidance related to TDRs for creditors that have adopted ASC 326 Financial Instruments - Credit Losses. We adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2020. ASC 326 requires the recognition of lifetime expected credit losses when a loan is originated or acquired, so the effect of credit losses that occur in loans modified in TDRs is already included in the allowance for credit losses.
ASU 2022-02 requires a creditor to apply the loan refinancing and restructuring guidance in ASC 310-20 (consistent with the accounting for other loan modifications) to determine whether a modification results in a new loan or a continuation of an existing loan. It also requires enhanced disclosures for modifications in the form of interest rate reductions, principal forgiveness, other-than-insignificant payment delays or term extensions (or combinations thereof) of loans made to borrowers experiencing financial difficulty. Disclosures are required regardless of whether a modification of a loan to a borrower experiencing financial difficulty results in a new loan. The objective of the disclosures is to provide information about the type and magnitude of modifications and the degree of their success in mitigating potential credit losses.
The amendments in this ASU were effective for fiscal years beginning after December 15, 2022, and interim periods therein. We adopted ASU 2022-02, as of January 1, 2023, using a modified retrospective transition approach. Results for reporting periods beginning after January 1, 2023 are presented under ASU 2022-02 while prior period amounts continue to be reported in accordance with previously applicable GAAP. Under the previously applicable accounting guidance, commercial TDRs were individually assessed to determine if a specific reserve was required in the allowance for credit losses, or ACL. The elimination of TDRs resulted in these loans being included in homogenous pools. The adoption of this ASU resulted in a day one cumulative effective adjustment of $0.6 million which increased our ACL and decreased retained earnings. Refer to Note 5 Loans and Allowance for Credit Losses for additional disclosures related to modifications of loans to borrowers experiencing financial difficulty as well as gross charge-off vintage disclosures.
Accounting Standards Updates Issued But Not Yet Adopted
Investments Equity Method and Joint Ventures (Topic 323) Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method
In March 2023, the FASB issued ASU 2023-02, Investments Equity Method and Joint Ventures (Topic 323): Accounting for Investments in Tax Credit Structures Using the Proportional Amortization Method to allow reporting entities to consistently account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits. If certain conditions are met, a reporting entity may elect to account for its tax equity investments by using the proportional amortization method regardless of the program from which it receives income tax credits, instead of only low-income-housing tax credit (“LIHTC”) structures. This amendment also eliminates certain LIHTC specific guidance aligning the accounting with other equity investments in tax credit structures. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. We are evaluating the accounting and disclosure requirements of ASU 2023-02 and do not expect them to have a material effect on our consolidated financial statements.

NOTE 3. FAIR VALUE MEASUREMENTS
We use fair value measurements when recording and disclosing certain financial assets and liabilities. Debt securities, equity securities and derivative financial instruments are recorded at fair value on a recurring basis. Additionally, from time to time, we may be required to record other financial instruments at fair value on a nonrecurring basis, such as loans held for sale, individually assessed loans, other real estate owned, or OREO, and other repossessed assets, mortgage servicing rights, or MSRs, and certain other assets.
Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction. In determining fair value, we use various valuation approaches, including market, income and cost approaches. The fair value standard establishes a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing an asset or liability, which are developed based on market data that we have obtained from independent sources. Unobservable inputs reflect our estimates of assumptions that market participants would use in pricing an asset or liability, which are developed based on the best information available in the circumstances.
The fair value hierarchy gives the highest priority to unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurement) and the lowest priority to unobservable inputs (Level 3 measurement). The fair value hierarchy is broken down into three levels based on the reliability of inputs as follows:
Level 1: valuation is based upon unadjusted quoted market prices for identical instruments traded in active markets.
Level 2: valuation is based upon quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by market data.
Level 3: valuation is derived from other valuation methodologies, including discounted cash flow models and similar techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in determining fair value.
A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

We evaluate securities with unrealized losses quarterly to determine if the decline in fair value has resulted from credit impairment or other factors. We do not believe any individual unrealized loss as of September 30, 2023 represents a credit impairment. There were 149 debt securities in an unrealized loss position at September 30, 2023 and 147 debt securities in an unrealized loss position at 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 the issuers. All debt securities were determined to be investment grade and paying principal and interest according to the contractual terms of the security. We do not intend to sell, and it is more likely than not that we will not be required to sell, the securities in an unrealized loss position before recovery of their amortized cost.

A payment default is defined as a loan having a payment past due 90 days or more after a modification took place. There were no loans that were modified within the last 12 months that had a payment default during the three and nine months ended September 30, 2023. Additionally, we had one commitment to lend an additional $0.2 million to borrowers experiencing financial difficulty that had a modification during the three and nine months ended September 30, 2023.
The effect of modifications made to borrowers experiencing financial difficulty is already included in the ACL because of the measurement methodologies used to estimate the ACL, therefore, a change to the ACL is generally not recorded upon modification. If principal forgiveness is provided, that portion of the loan will be charged-off, resulting in a reduction of the amortized cost basis and a corresponding adjustment to the ACL. An assessment of whether the borrower is experiencing financial difficulty is made on the date of a modification.
Troubled Debt Restructurings
Prior to the adoption of ASU 2022-02, we evaluated all substandard commercial and consumer loans that had experienced a forbearance or modification of existing terms to determine if they should be designated as troubled debt restructurings, or TDRs.
TDRs returned to accruing status if the ultimate collectability of all contractual amounts due, according to the restructured agreement, was not in doubt and there was a period of a minimum of six months of satisfactory payment performance by the borrower either immediately before or after the restructuring. There was one $0.2 million TDR returned to accruing status during 2022.

Allowance for Credit Losses
We maintain an ACL at a level determined to be adequate to absorb estimated expected credit losses within the loan portfolio over the contractual life of an instrument that considers our historical loss experience, current conditions and forecasts of future economic conditions as of the balance sheet date. We develop and document a systematic ACL methodology based on the following portfolio segments: 1) Commercial Real Estate, or CRE, 2) Commercial and Industrial, or C&I, 3) Commercial Construction, 4) Business Banking, 5) Consumer Real Estate and 6) Other Consumer.
The following are key risks within each portfolio segment:
CRE—Loans secured by commercial purpose real estate, including both owner-occupied properties and investment properties for various purposes such as hotels, retail, multifamily and health care. Operations of the individual projects and global cash flows of the debtors are the primary sources of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the collateral type and the business prospects of the lessee, if the project is not owner-occupied.
C&I—Loans made to operating companies or manufacturers for the purpose of production, operating capacity, accounts receivable, inventory or equipment financing. Cash flow from the operations of the company is the primary source of repayment for these loans. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the industry of the company. Collateral for these types of loans often does not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt.
Commercial Construction—Loans made to finance construction of buildings or other structures, as well as to finance the acquisition and development of raw land for various purposes. While these loans are generally confined to the construction/development period, if there are problems, the project may not be completed, and as such, may not provide sufficient cash flow on its own to service the debt or have sufficient value in a liquidation to cover the outstanding principal. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the type of project and the experience and resources of the developer.
Business Banking—Commercial purpose loans made to small businesses that are standard, non-complex products evaluated through a streamlined credit approval process that has been designed to maximize efficiency while maintaining high credit quality standards that meet small business market customers’ needs. The business banking portfolio is monitored by utilizing a standard and closely managed process focusing on behavioral and performance criteria. The condition of the local economy is an important indicator of risk, but there are also more specific risks depending on the collateral type and business.
Consumer Real Estate—Loans secured by first and second liens such as 1-4 family residential mortgages, home equity loans and home equity lines of credit. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The state of the local housing market can also have a significant impact on this segment because low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.
Other Consumer—Loans made to individuals that may be secured by assets other than 1-4 family residences, as well as unsecured loans. This segment includes auto loans, unsecured loans and lines of credit. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.
Management monitors various credit quality indicators for the commercial, business banking and consumer loan portfolios, including changes in risk ratings, nonperforming status and delinquency on a monthly basis.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
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 within the pass rating generally have a lower risk of loss than loans risk rated as special mention or substandard.
Our risk ratings are consistent with regulatory guidance and are as follows:
Pass—The loan is currently performing and is of high quality.
Special Mention—A special mention loan has potential weaknesses that warrant management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects or in the strength of our credit position at some future date.
Substandard—A substandard loan is not adequately protected by the net worth and/or paying capacity of the borrower or by the collateral pledged, if any. Substandard loans have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. These loans are characterized by the distinct possibility that we will sustain some loss if the deficiencies are not corrected.
Doubtful—Loans classified doubtful have all the weaknesses inherent in those classified substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently known facts, conditions and values, highly questionable and improbable.
The following tables present loan balances by year of origination and internally assigned risk rating for our portfolio segments as of the dates presented:

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
We monitor the delinquent status of the commercial and consumer portfolios on a monthly basis. Loans are considered nonaccrual when interest and principal are 90 days or more past due or management has determined that a material deterioration in the borrower’s financial condition exists. The risk of loss is generally highest for nonaccrual loans.

NOTE 7. COMMITMENTS AND CONTINGENCIES
Commitments
In the normal course of business, we offer off-balance sheet credit arrangements to enable our customers to meet their financing objectives. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated financial statements. Our exposure to credit loss, in the event the customer does not satisfy the terms of the agreement, equals the contractual amount of the obligation less the value of any collateral. We apply the same credit policies in making commitments and standby letters of credit that are used for the underwriting of loans to customers. Commitments generally have fixed expiration dates, annual renewals or other termination clauses and may require payment of a fee. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
The following table sets forth our commitments and letters of credit as of the dates presented:

(dollars in thousands) | September 30, 2023 |  | December 31, 2022
Commitments to extend credit |  | $ | 2,697,493 |  |  |  | $ | 2,713,586 |
Standby letters of credit |  | 53,061 |  |  |  | 64,356 |
Total |  | $ | 2,750,554 |  |  |  | $ | 2,777,942 |

Allowance for Credit Losses on Unfunded Loan Commitments
We maintain an allowance for credit losses on unfunded commercial and consumer lending commitments and letters of credit to provide for the risk of loss inherent in these arrangements. The allowance is computed using a methodology similar to that used to determine the allowance for credit losses for loans, modified to take into account the probability of a draw-down on the commitment. The provision for credit losses on unfunded loan commitments is included in the provision for credit losses on our Condensed Consolidated Statements of Comprehensive Income (Loss). The allowance for unfunded commitments is included in other liabilities in the Consolidated Balance Sheets.

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

NOTE 9. SHARE REPURCHASE PLAN
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 permits 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. 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 common stock, legal and contractual requirements, applicable securities laws and S&T's financial performance. The repurchase plan does not obligate us to repurchase any particular number of shares. We expect to fund any repurchases from cash on hand and internally generated funds. Any share repurchases will not begin until permissible under applicable laws.
The following table presents repurchase activity for the periods presented:

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Management’s Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, represents an overview of our consolidated results of operations and financial condition and highlights material changes in our financial condition and results of operations for the three and nine months ended September 30, 2023 and 2022. Our MD&A should be read in conjunction with our Consolidated Financial Statements and Notes. The results of operations reported in the accompanying Consolidated Financial Statements are not necessarily indicative of results to be expected in future periods.
Important Note Regarding Forward-Looking Statements
This quarterly report on Form 10-Q contains or incorporates statements that we believe are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements generally relate to our financial condition, results of operations, plans, objectives, outlook for earnings, revenues, expenses, capital and liquidity levels and ratios, asset levels, asset quality, financial position and other matters regarding or affecting S&T and its future business and operations. Forward-looking statements are typically identified by words or phrases such as “will likely result,” “expect,” “anticipate,” “estimate,” “forecast,” “project,” “intend,” “believe,” “assume,” “strategy,” “trend,” “plan,” “outlook,” “outcome,” “continue,” “remain,” “potential,” “opportunity,” “comfortable,” “current,” “position,” “maintain,” “sustain,” “seek,” “achieve,” and variations of such words and similar expressions, or future or conditional verbs such as will, would, should, could or may. Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. The matters discussed in these forward-looking statements are subject to various risks, uncertainties and other factors that could cause actual results and trends to differ materially from those made, projected, or implied in or by the forward-looking statements depending on a variety of uncertainties or other factors including, but not limited to: credit losses and the credit risk of our commercial and consumer loan products; changes in the level of charge-offs and changes in estimates of the adequacy of the allowance for credit losses, or ACL; 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; 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; environmental, social and governance 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.
Many of these factors, as well as other factors, are described elsewhere in this report, and in our 2022 Form 10-K, 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.

Critical Accounting Policies and Estimates
We view critical accounting policies to be those which are highly dependent on subjective or complex estimates, assumptions and judgments and where changes in those estimates and assumptions could have a significant impact on the Consolidated Financial Statements. Further, we view critical accounting estimates as those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial condition or results of operations. Our critical accounting policies and estimates as of September 30, 2023 remained unchanged from the disclosures presented in our 2022 Form 10-K under Part II, Item 7 - “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”
Overview
We are a bank holding company that is headquartered in Indiana, Pennsylvania with assets of $9.5 billion at September 30, 2023. We operate in Pennsylvania and Ohio providing a full range of financial services with retail and commercial banking products, cash management services, trust and brokerage services. Our common stock trades on the NASDAQ Global Select Market under the symbol “STBA”.
We earn revenue primarily from interest on loans and securities and fees charged for financial services provided to our customers. We incur expenses for the cost of deposits and other funding sources, provision for credit losses and other operating costs such as salaries and employee benefits, data processing, occupancy and tax expense.
Our purpose is building a better future together through people-forward banking. We believe that all banking should be personal. We cultivate relationships rooted in trust, strengthened by going above and beyond and renewed with every interaction. Our strategic priorities for 2023 and beyond will be focused on our deposit franchise, core profitability, asset quality and talent and engagement.
During the first quarter of 2023, the banking industry experienced significant volatility with several high-profile bank failures and industry wide concerns related to liquidity, deposit outflows, unrealized securities losses and eroding consumer confidence in the banking system. Despite these negative industry developments, our liquidity position and balance sheet remain well-positioned. We have a well-diversified deposit base with a balance mix of 57.4 percent personal, 35.2 percent business, 5.0 percent public funds and 2.4 percent brokered deposits at September 30, 2023. Total deposits were relatively unchanged compared to December 31, 2022. We have total uninsured deposits of $2.2 billion, or 31 percent of our total deposit base. At September 30, 2023, we had remaining borrowing availability of $3.8 billion, which includes $2.3 billion with the FHLB of Pittsburgh, $770 million from the Federal Reserve Discount Window and $676 million from the Federal Reserve Bank Term Funding Program. Furthermore, our capital remains strong with a Common Equity Tier 1 Ratio of 13.11 percent and a total capital ratio of 15.01 percent at September 30, 2023.

(1) Reconciled to GAAP in the "Explanation of Use of Non-GAAP Financial Measures" section of this MD&A.

We recognized net income of $33.5 million, or $0.87 per diluted share, for the three months ended September 30, 2023 compared to net income of $37.2 million, or $0.95 per diluted share, for the same period in 2022. Net income decreased $3.7 million for the three months ended September 30, 2023 compared to the same period in 2022 due to an increase in the provision for credit losses of $3.0 million, a decrease in noninterest income of $2.6 million and an increase in noninterest expense of $3.2 million offset by an increase in net interest income of $3.6 million and a decrease in income tax expense of $1.4 million. We recognized net income of $107.7 million, or $2.78 per diluted share, for the nine months ended September 30, 2023 compared to net income of $95.3 million, or $2.43 per diluted share, for the same period in 2022. The increase in net income of $12.4 million for the nine months ended September 30, 2023 compared to the same period in 2022 is primarily related to an increase

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
in net interest income of $37.6 million offset by an increase in the provision for credit losses of $11.8 million, an increase in noninterest expense of $8.7 million, a decrease in noninterest income of $3.1 million and an increase in income tax expense of $1.6 million.
Net interest income increased $3.6 million and $37.6 million for the three and nine months ended September 30, 2023 compared to the same periods in 2022. Interest and dividend income increased $33.1 million and $113.7 million for the three and nine months ended September 30, 2023 compared to the same periods in 2022. Interest expense increased $29.5 million and $76.1 million for the three and nine months ended September 30, 2023 compared to the same periods in 2022. Net interest margin, or NIM, on an FTE basis (non-GAAP) increased 5 and 63 basis points for the three and nine months ended September 30, 2023 compared to the same periods 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. NIM is reconciled to net interest margin adjusted to an FTE basis (non-GAAP) in the "Explanation of Use of Non-GAAP Financial Measures" section of this MD&A.
The provision for credit losses increased $3.0 million and $11.8 million to $5.5 million and $17.0 million for the three and nine months ended September 30, 2023 compared to $2.5 million and $5.2 million for the same periods in 2022. The increase in the provision for credit losses for the three and nine months ended September 30, 2023 compared to the same periods in 2022 was due to increases in net loan charge-offs and in our qualitative reserve.
Noninterest income decreased $2.6 million and $3.1 million to $12.2 million and $39.6 million for the three and nine months ended September 30, 2023 compared to the same periods in 2022. Other noninterest income decreased $1.7 million for the three months ended September 30, 2023 primarily due to a valuation adjustment for our commercial loan swaps of $0.9 million as well a gain on the sale of OREO of $0.6 million in the same period in 2022. Mortgage banking decreased $0.1 million and $1.0 million for the three and nine months ended September 30, 2023 compared to the same periods in 2022 due to a continued decline in loan sale activity caused by rising interest rates and a shift to holding originated mortgage loans on our balance sheet. Debit and credit card income decreased $0.1 million and $0.9 million for the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022 due to decreased debit card incentive income and timing of referral merchant revenue.
Noninterest expense increased $3.2 million to $52.8 million for the three months ended September 30, 2023 and increased $8.7 million to $154.1 million for the nine months ended September 30, 2023 compared to the same periods in 2022. Salaries and employee benefits increased $0.8 million for the three months ended September 30, 2023 due to higher salary expense caused by new positions and increased restricted stock expense, offset by decreases in expense for medical claims, employee pension and incentive payouts. Salaries and employee benefits increased $5.3 million for the nine months ended September 30, 2023 due to higher salary expense as well as a change in the valuation of our deferred compensation plan, which has a corresponding offset in other income within noninterest income resulting in no impact to net income, partially offset by a decrease in incentive expense.
The provision for income taxes decreased $1.4 million to $7.8 million for the three months ended September 30, 2023 compared to $9.2 million for the same period in 2022 due to an increase in tax credits and increased $1.6 million to $25.0 million for the nine months ended September 30, 2023 compared to $23.4 million for the same period in 2022 mainly due to an increase in income before taxes. Our effective tax rate was 18.9 percent for both the three and nine months ended September 30, 2023 compared to 19.8 percent and 19.7 percent for the three and nine months ended September 30, 2022. The decrease in our effective tax rate for the three and nine month periods ended September 30, 2023 was primarily due to an increase in tax credits compared to the same periods in 2022.
Explanation of Use of Non-GAAP Financial Measures
In addition to traditional financial measures presented in accordance with GAAP, our management uses, and this quarterly 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.

Three and Nine Months Ended September 30, 2023 Compared to

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.

Certificates of deposit increased $419.6 million and $213.5 million and the average rate paid increased 293 and 258 basis points for the three and nine months ended September 30, 2023 compared to the same periods in 2022. The increase in certificates of deposit was primarily due to higher interest rates resulting in customers moving deposits to higher yield accounts. Average borrowings increased $580.5 million and $478.4 million and the average rate paid on borrowings increased 225 and 341 basis points for the three and nine months ended September 30, 2023 compared to the same periods in 2022 primarily due to decreased deposit balances and increased loans.

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 $3.0 million and $11.8 million to $5.5 million and $17.0 million for the three and nine months ended September 30, 2023 compared to $2.5 million and $5.2 million for the same periods in 2022. The increase in the provision for credit losses for the three and nine months ended September 30, 2023 compared to the same periods in 2022 was primarily due to increases in net loan charge-offs and in our qualitative reserve. 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. We also had an increase in our quantitative reserve due to downgrades in our C&I portfolio and loan growth in our consumer real estate portfolio.
For the three and nine months ended September 30, 2023, we had net loan charge-offs of $3.7 million and $9.6 million compared to $0.7 million and $1.7 million for the same periods in 2022. During the nine months ended September 30, 2023, our most significant charge-offs were three C&I relationships totaling $15.9 million, which was partially offset by a $9.3 million recovery from a customer fraud that occurred in 2020.

Noninterest income decreased $2.6 million and $3.1 million to $12.2 million and $39.6 million for the three and nine months ended September 30, 2023 compared to the same periods in 2022. Other noninterest income decreased $1.7 million for the three months ended September 30, 2023 primarily due to a valuation adjustment for our commercial loan swaps of $0.9 million as well as a gain on the sale of OREO of $0.6 million that occurred in the three months ending September 30, 2022 compared to no OREO activity in the same period for 2023. Other noninterest income remained relatively unchanged for the nine months ended September 30, 2023 compared to the same period in 2022 despite an increase of $3.0 million related to a change in the valuation of our deferred compensation plan, which has a corresponding offset in salaries and employee benefits resulting in no impact to net income. This increase was offset by a decrease of $0.8 million related to a reduction of commercial loan swap income and a $0.9 million valuation adjustment for our commercial loan swaps as well as a decrease of $0.5 million in gain on the sale of OREO compared to the same period in 2022. Wealth management decreased $0.2 million and $0.6 million for the three months and nine months ended September 30, 2023 compared to the same periods in 2022 due to decreased trust income fees. Mortgage banking decreased $0.1 million and $1.0 million for the three and nine months ended September 30, 2023 compared to the same periods in 2022 due to a continued decline in loan sale activity caused by rising interest rates and a shift to holding originated mortgage loans on our balance sheet. Debit and credit card income decreased $0.1 million and $0.9 million for the three and nine months ended September 30, 2023 compared to the three and nine months ended September 30, 2022 due to decreased debit card incentive income and timing of referral merchant revenue.

The loan portfolio represents the most significant source of interest income for us. The risk that borrowers will be unable to pay such obligations is inherent in the loan portfolio. Other conditions such as downturns in the borrower’s industry or the overall economic climate can significantly impact the borrower’s ability to pay.
Total portfolio loans increased $331.9 million, or 4.6 percent, to $7.5 billion at September 30, 2023 compared to $7.2 billion at December 31, 2022.
As of September 30, 2023, 67 percent of our total loans were variable rate loans and 33 percent were fixed rate loans compared to 72 percent variable rate and 28 percent fixed rate at December 31, 2022. Commercial loans, including CRE, C&I and commercial construction, comprised 70.7 percent of total portfolio loans at September 30, 2023 and 73.0 percent at December 31, 2022. The commercial loan portfolio increased $63.6 million at September 30, 2023 compared to December 31, 2022 due to an increase of $158.1 million in CRE primarily due to fewer loan prepayments and decreases of $83.6 million in C&I and $10.9 million in construction loans as a result of loan pay-offs and lower origination volume due to the current macro environment.
Consumer loans represent 29.3 percent of our total portfolio loans at September 30, 2023 and 27.0 percent at December 31, 2022. The consumer loan portfolio increased $268.4 million at September 30, 2023 due to growth in our consumer real estate portfolio of $277.9 million compared to December 31, 2022. Consistent with 2022, we continue to retain consumer real estate loans on our balance sheet as portfolio loans versus selling these loans due to the loan pricing in the secondary market.
Allowance for Credit Losses
We maintain an ACL at a level determined to be adequate to absorb estimated expected credit losses within the loan portfolio over the contractual life of an instrument that considers our historical loss experience, current conditions and forecasts of future economic conditions as of the balance sheet date. We develop and document a systematic ACL methodology based on the following portfolio segments: 1) Commercial Real Estate, or CRE, 2) Commercial and Industrial, or C&I, 3) Commercial Construction, 4) Business Banking, 5) Consumer Real Estate and 6) Other Consumer. Refer to Part 1. Financial Information, Note 5 Loans and Allowance for Credit Losses for details on our portfolio segments.

Allowance for credit losses as a percentage of total portfolio loans | 1.44 | % |  | 1.41 | %
Allowance for credit losses to nonaccrual loans | 854 | % |  | 532 | %

(1) Year-to-date net charge-offs annualized
Net loan charge-offs were $9.6 million, or 0.18 percent of average loans, for the nine months ended September 30, 2023. Refer to the "Provision for Credit Losses" section of this MD&A for further details.
The ACL was $108.2 million, or 1.44 percent of total portfolio loans, at September 30, 2023 compared to $101.3 million, or 1.41 percent of total portfolio loans, at December 31, 2022. The increase in the ACL of $6.9 million was primarily due to a $4.9 million increase in our qualitative reserve 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. We also had a $2.0 million increase in our quantitative reserve primarily due to downgrades in our C&I portfolio and loan growth in our consumer real estate portfolio.
Substandard loans increased $14.3 million to $177.4 million at September 30, 2023 compared to $163.1 million at December 31, 2022. The increase in substandard loans was primarily due to risk rating downgrades from special mention to substandard in our C&I and CRE portfolios which occurred during the nine months ended September 30, 2023. Special mention loans decreased $26.8 million to $194.3 million at September 30, 2023 compared to $221.1 million at December 31, 2022. The decrease in special mention loans was primarily due to the risk rating downgrades from special mention to substandard and loan payoffs.
Our allowance for credit losses on unfunded commercial loan commitments and letters of credit provide for the risk of expected loss in these arrangements. The allowance is computed using a methodology similar to that used to determine the ACL for loans, modified to take into account the probability of a draw-down on the commitment. The provision for credit losses on unfunded loan commitments is included in the provision for credit losses on our Condensed Consolidated Statements of Comprehensive Income (Loss). The allowance for unfunded loan commitments increased $1.1 million to $9.3 million at September 30, 2023 compared to $8.2 million at December 31, 2022. The increase was due to increased loss rates and an increase in unused C&I commitments. The allowance for unfunded commitments is included in other liabilities in the Consolidated Balance Sheets.

Our policy is to place loans in all categories in nonaccrual status when collection of interest or principal is doubtful, or generally when interest or principal payments are 90 days or more past the contractual due date. Nonaccrual loans decreased $6.4 million, or 33.5 percent, to $12.7 million at September 30, 2023 compared to $19.1 million at December 31, 2022. The decrease in nonaccrual loans primarily related to the payoff of a $5.4 million CRE loan during the nine months ended September 30, 2023.
Deposits
Deposits are our primary source of funds. We have a well-diversified deposit base with a balance mix of 57.4 percent personal, 35.2 percent business, 5.0 percent public funds and 2.4 percent brokered at September 30, 2023.

Total Deposits |  | $ | 7,222,897 |  |  |  | $ | 7,219,970 |  |  |  | $ | 2,927 |

Our total deposits were $7.2 billion at both September 30, 2023 and December 31, 2022. Certificates of deposit increased $553.3 million compared to December 31, 2022 due to migration from other deposit categories as customers continue to seek higher interest rates, new deposit inflows and the issuance of $175.0 million of brokered certificates of deposit in 2023. We had no brokered deposits at December 31, 2022. 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 $154.5 million to $221.8 million at September 30, 2023 compared to $67.3 million at December 31, 2022. We have total uninsured deposits of $2.2 billion, or 31 percent of our total deposit base, compared to $2.5 billion, or 34 percent, at December 31, 2022.

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 and attract new deposits, mitigating any funding dependency on other more volatile funding sources. Refer to the "Financial Condition as of September 30, 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, or FHLB, of Pittsburgh, federal funds lines with other financial institutions and the brokered deposit market. Additionally, S&T has borrowing availability through the Federal Reserve Discount Window and the Federal Reserve Bank Term Funding Program, or 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 program, 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 is charged at a fixed rate equal to the one-year overnight index swap rate plus 10 basis points with no prepayment penalty. As of September 30, 2023, we have $675.8 million of collateral available to pledge under the program and no outstanding balance.
Available borrowing capacity exceeds uninsured deposits of $2.2 billion. The following table summarizes funding sources available as of the dates presented:

| September 30, 2023 |  | December 31, 2022
(dollars in thousands) | Borrowing Capacity | Balance | Available |  | Borrowing Capacity | Balance | Available

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

We have contractual obligations representing required future payments on certificates of deposit, junior subordinated debt securities, short-term borrowings, long-term borrowings, operating and capital leases and purchase obligations. See the Liquidity and Capital Resources portion of our Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2022 Form 10-K for more information on these future cash outflows. Certificates of deposit increased $553.3 million to $1.5 billion at September 30, 2023 compared to December 31, 2022 and short-term borrowings increased $260.0 million to $630.0 million at September 30, 2023 compared to December 31, 2022. Other than these changes, there have been no material changes to the contractual obligations previously disclosed in our 2022 Form 10-K.
An important component of our ability to effectively respond to potential liquidity stress events is maintaining a cushion of highly liquid assets. Highly liquid assets are those that can be converted to cash quickly to meet financial obligations. ALCO policy guidelines define a ratio of highly liquid assets to total assets by graduated risk tolerance levels of minimal, moderate and high. At September 30, 2023, S&T Bank had $885.6 million in highly liquid assets which consisted primarily of $162.6 million in interest-bearing deposits with banks and $722.7 million in unpledged securities. This resulted in a highly liquid assets to total assets ratio of 9.4 percent at September 30, 2023.
We continue to maintain a strong capital position with our leverage ratio at 11.12 percent at September 30, 2023 compared to 11.06 percent at December 31, 2022, both in excess of the well-capitalized regulatory guideline of 5.00 percent. We continue

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 due to the COVID-19 pandemic. The IFR provides financial institutions that adopted 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.
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 September 30, 2023, we had not issued any securities pursuant to this shelf registration statement.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Market risk is defined as the degree to which changes in interest rates, foreign exchange rates, commodity prices or equity prices can adversely affect a financial institution’s earnings or capital. For most financial institutions, including S&T, market risk primarily reflects exposures to changes in interest rates. Interest rate fluctuations affect earnings by changing net interest income and other interest-sensitive income and expense levels. Interest rate changes also affect capital by changing the net present value of a bank’s future cash flows, and the cash flows themselves, as rates change. Accepting this risk is a normal part of banking and can be an important source of profitability and enhancing shareholder value. However, excessive interest rate risk can threaten a bank’s earnings, capital, liquidity and solvency. Our sensitivity to changes in interest rate movements is continually monitored by 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.

Item 3. 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 September 30, 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 September 30, 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. 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 September 30, 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.
In addition to rate shocks and EVE analyses, we perform a market risk stress test at least annually. The market risk stress test includes sensitivity analyses and simulations. Sensitivity analyses are performed to help us identify which model assumptions cause the greatest impact on pretax net interest income. Sensitivity analyses may include changing prepayment behavior of loans and securities with optionality and the impact of interest rate changes on non-maturity deposit products. Simulation analyses may include the potential impact of rate changes other than the policy guidelines, yield curve shape changes, significant balance mix changes and various growth scenarios.
Item 4. CONTROLS AND PROCEDURES
Evaluation of Disclosure Controls and Procedures
Under the supervision and with the participation of S&T’s Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO (its principal executive officer and principal financial officer, respectively), management has evaluated the effectiveness of the design and operation of S&T’s disclosure controls and procedures as of September 30, 2023. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time periods required by the Securities and Exchange Commission, or the SEC, and that such information is accumulated and communicated to S&T’s management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.
Based on and as of the date of such evaluation, our CEO and CFO concluded that the design and operation of our disclosure controls and procedures were effective in all material respects, as of the end of the period covered by this report.
Changes in Internal Control over Financial Reporting
During the quarter ended September 30, 2023, there were no changes made to S&T’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that materially affected, or are reasonably likely to materially affect, S&T’s internal control over financial reporting.

Difficult market conditions, including rapidly rising interest rates and several bank receiverships may adversely affect our business, results of operations, liquidity and stock price. 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.
The rapid rise in interest rates during 2022, the resulting industry-wide reduction in the fair value of securities portfolios, and the related bank runs resulting in the takeover by the FDIC of two banks placed in receivership in March 2023, have caused a current 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 two banks was done in a manner that fully protects depositors, it is uncertain whether the steps taken by the government will be sufficient to calm the financial markets, alleviate concerns with respect to the U.S. banking system, reduce the risk of significant depositor withdrawals at other financial institutions and thereby reduce the risk of additional banks becoming insolvent, particularly in light of an additional bank being placed in receivership in the second quarter of 2023. 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 potential additional regulation of the 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.

(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 permits 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. 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 common stock, legal and contractual requirements, applicable securities laws and S&T's financial performance. The repurchase plan does not obligate us to repurchase any particular number of shares. We expect to fund repurchases from cash on hand and internally generated funds. Share repurchases will not occur unless permissible under applicable laws.
(2)Includes excise tax on repurchases, net of issuances for restricted stock awards.
