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, 2020,2021, filed with the Securities and Exchange Commission, or SEC, on March 1, 2021.February 28, 2022. 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.
On June 5, 2019 we entered into an agreement to acquire DNB Financial Corporation, or DNB, and the transaction was completed on November 30, 2019. Refer to Note 2, Business Combinations in our Annual Report on Form 10-K for the year ended December 31, 2020 for further details on the merger.
Reclassification
Amounts in prior period financial statements and footnotes are reclassified whenever necessary to conform to the current period presentation. Reclassifications had no effect on our 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 Update
Income Taxes (Topic 740): Simplifying the AccountingPolicy for Income Taxes
In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptionsDerivative Instruments and improve the consistent application of GAAP by clarifying and amending other existing guidance. We adopted this ASU on January 1, 2021. The amendments in this ASU did not impact our consolidated financial statements.Hedging Activities


During the three months ended March 31, 2022, we entered into 4 interest rate swaps designated as cash flow hedges to hedge the variable cash flows associated with existing variable rate assets. We have updated our accounting policy for derivative instruments and hedging activities to include hedge accounting.

All derivatives are evaluated at inception to determine whether it is a hedging or non-hedging activity. The accounting for changes in the fair value of derivatives depends on whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. As long as the cash flow hedge continues to qualify for hedge accounting, the entire change in the fair value of the hedging instrument is recorded in Accumulated Other Comprehensive Income (Loss), or AOCI, and recognized in earnings as the hedged transaction affects earnings.





Refer to our Annual Report on Form 10-K for the year ended December 31, 2021, as filed with the SEC on February 28, 2022, for our complete Accounting Policy for Derivative Instruments and Hedging Activities.

Recently Adopted Accounting Standards Issued Not Yet AdoptedUpdates, 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 provide 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 provide optional expedients and exceptions for applying GAAP to loan and lease agreements, derivative contracts, and other transactions affected by the anticipated transition away from LIBOR toward new interest rate benchmarks. Modified contracts that meet certain scope guidance are eligible for relief from the modification accounting requirements in GAAP. The optional guidance generally allows 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 are 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 clarifies 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. Specifically, certain provisions in Topic 848, if elected by an entity, apply to derivative instruments that use an interest rate for margining, discounting, or contract price alignment that is modified as a result of reference rate reform. The guidance is effective for all entities as of March 12, 2020 through December 31, 2022. We adopted ASU 2020-04 and ASU 2021-01 on January 1, 2022. We are utilizing the LIBOR transition relief as contract modifications are made during the course of the reference rate reform transition period. ASU 2020-04 and ASU 2021-01 did not have a material impact on our consolidated financial statements.
Accounting Standards Issued But Not Yet Adopted
Accounting Policy for Troubled Debt Restructurings and Vintage Disclosure
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. Once applying ASC 326, the required accounting and disclosures for a loan modified in a TDR no longer provide decision-useful information. 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 310-205 (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 are effective for fiscal years beginning after December 15, 2022, and interim periods therein. We are evaluating the impact of this ASU, and webut do not expect the amendments in this ASUit to materiallyhave a material impact 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 assets 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. Our policy is to recognize transfers between any of the fair value hierarchy levels at the end of the reporting period in which the transfer occurred.
The following are descriptions of the valuation methodologies that we use for financial instruments recorded at fair value on either a recurring or nonrecurring basis.
Recurring Basis
Available-for-Sale Debt Securities
We obtain fair values for debt securities from a third-party pricing service which utilizes several sources for valuing fixed-income securities. We validate prices received from our pricing service through comparison to a secondary pricing service and broker quotes. We review the methodologies of the pricing services which provide us with a sufficient understanding of the valuation models, assumptions, inputs and pricing to reasonably measure the fair value of our debt securities. The fair value of U.S. treasury securities are based on quoted market prices in active markets and are classified as Level 1. The market valuation sources for other debt securities include observable inputs rather than significant unobservable inputs and are classified as Level 2. The service provider utilizes pricing models that vary by asset class and include available trade, bid and other market information. Generally, the methodologies include broker quotes, proprietary models and extensive quality control programs.

Equity Securities
Marketable equity securities that have an active, quotable market are classified as Level 1. Marketable equity securities that are quotable, but are thinly traded or inactive, are classified as Level 2. Marketable equity securities that are not readily traded and do not have a quotable market are classified as Level 3.

Securities Held
There have been no changes in a Deferred Compensation Plan
We use quoted market pricesour valuation methodologies during the three months ended March 31, 2022. Refer to determine the fair valueNote 1 of our equity security assets. These securities are reported at fair value withAnnual Report on Form 10-K for the gains and losses included in noninterest income in our Condensed Consolidated Statements of Comprehensive Income. These assets are held in a deferred compensation plan and are invested in readily quoted mutual funds. Accordingly, these assets are classified as Level 1. Deferred compensation plan assets are reported in other assets in the Consolidated Balance Sheets.
Derivative Financial Instruments
We use derivative instruments, including interest rate swapsyear ended December 31, 2021 for commercial loans with our customers, interest rate lock commitments and forward commitments related to the sale of mortgage loans in the secondary market. We calculate the fair value for derivatives using accepted valuation techniques, including discounted cash flow analysismore information on the expected cash flows of each derivative. Each valuation considers the contractual terms of the derivative, including the period to maturity, and uses observable market-based inputs, such as interest rate curves and implied volatilities. Accordingly, derivatives are classified as Level 2. We incorporate credit valuation adjustments into the valuation models to appropriately reflect both our own nonperformance risk and the respective counterparties’ nonperformance risk in calculating fair value measurements. In adjusting the fair value of our derivative contractsmethodologies that we use for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements and collateral postings.
Nonrecurring Basis
Loans Held for Sale
Loans held for sale are carried at the lower of cost or market and consist of 1-4 family residential loans originated for sale in the secondary market and, from time to time, certain loans are transferred from the loan portfolio to loans held for sale, all of which are carried at the lower of cost or fair value. The fair value of 1-4 family residential loans is based on the principal or most advantageous market currently offered for similar loans using observable market data. The fair value of the loans transferred from the loan portfolio is based on the amounts offered for these loans in currently pending sales transactions. Loans held for sale marked to fair value are classified as Level 2.
Loans Individually Evaluated
Loans that are individually evaluated to determine whether a specific allocation of ACL is needed are reported at the lower of amortized cost or fair value. Fair value is determined using the following methods: 1) the present value of expected future cash flows discounted at the loan’s original effective interest rate; 2) the loan’s observable market price; or 3) the fair value of the collateral less estimated selling costs when the loan is collateral dependent and we expect to liquidate the collateral. However, if repayment is expected to come from the operation of the collateral, rather than liquidation, then we do not consider estimated selling costs in determining the fair value of the collateral. Collateral values are generally based upon appraisals by approved, independent state certified appraisers. Appraisals may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or our knowledge of the borrower and the borrower’s business. Loans individually evaluated that are marked to fair value are classified as Level 3.
OREO and Other Repossessed Assets
OREO and other repossessed assets obtained in partial or total satisfaction of a loan are recorded at the lower of recorded investment in the loan or fair value less cost to sell. Subsequent to foreclosure, these assets are carried at the lower of the amount recorded at acquisition date or fair value less cost to sell. Accordingly, it may be necessary to record nonrecurring fair value adjustments. Fair value, when recorded, is generally based upon appraisals by approved, independent state certified appraisers. Appraisals on OREO may be discounted based on our historical knowledge, changes in market conditions from the time of appraisal or other information available to us. OREO and other repossessed assets marked to fair value are classified as Level 3. OREO and other repossessed assets are reported in other assets in the Consolidated Balance Sheets.

NOTE 3. FAIR VALUE MEASUREMENTS - continued
Mortgage Servicing Rights
MSRs are reported pursuant to the amortization method and evaluated for impairment quarterly by comparing the carrying to the fair value of the MSRs. Fair value of MSRs is determined by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSRs. MSRs are considered impaired if the carrying value exceeds fair value. Since the valuation model includes significant unobservable inputs as listed above, MSRs are classified as Level 3. MSRs are reported in other assets in the Consolidated Balance Sheets and are amortized into mortgage banking income in the Condensed Consolidated Statements of Comprehensive Income.
Financial Instruments
In addition to financial instruments recorded at fair value in our financial statements, fair value accounting guidance requires disclosure of the fair value of all of an entity’s assets and liabilities that are considered financial instruments. The majority of our assets and liabilities are considered financial instruments. Many of these instruments lack an available trading market as characterized byon a willing buyer and a willing seller engaged in an exchange transaction. Also, it is our general practice and intent to hold our financial instruments to maturity and to not engage in tradingrecurring or sales activities with respect to such financial instruments. For fair value disclosure purposes, we substantially utilize the fair value measurement criteria as required and explained above. In cases where quoted fair values are not available, we use present value methods to determine the fair value of our financial instruments.
Cash and Cash Equivalents
The carrying amounts reported in the Consolidated Balance Sheets for cash and due from banks, including interest-bearing deposits, approximate fair value.
Loans
Our methodology to fair value loans includes an exit price notion. The fair value of variable rate loans that may reprice frequently at short-term market rates is based on carrying values adjusted for liquidity and credit risk. The fair value of variable rate loans that reprice at intervals of one year or longer, such as adjustable rate mortgage products, is estimated using discounted cash flow analyses that utilize interest rates currently being offered for similar loans and adjusted for liquidity and credit risk. The fair value of fixed rate loans is estimated using a discounted cash flow analysis that utilizes interest rates currently being offered for similar loans adjusted for liquidity and credit risk.
Bank Owned Life Insurance
Fair value approximates net cash surrender value of bank owned life insurance, or BOLI.
Federal Home Loan Bank, or FHLB, and Other Restricted Stock
It is not practical to determine the fair value of our FHLB and other restricted stock due to the restrictions placed on the transferability of these stocks; it is presented at carrying value.
Collateral Receivable
Collateral receivable is cash that is made available to counterparties as collateral for our interest rate swaps. The carrying amount included in other assets on our Consolidated Balance Sheets approximates fair value.
Deposits
The fair values disclosed for deposits without defined maturities (e.g., noninterest and interest-bearing demand, money market and savings accounts) are by definition equal to the amounts payable on demand. The carrying amounts for variable rate, fixed-term time deposits approximate their fair values. Estimated fair values for fixed rate and other time deposits are based on discounted cash flow analysis using interest rates currently offered for time deposits with similar terms. The carrying amount of accrued interest approximates fair value.

Short-Term Borrowings
The carrying amounts of securities sold under repurchase agreements, or REPOs, and other short-term borrowings approximate their fair values.
Long-Term Borrowings
The fair values disclosed for fixed rate long-term borrowings are determined by discounting their contractual cash flows using current interest rates for long-term borrowings of similar remaining maturities. The carrying amounts of variable rate long-term borrowings approximate their fair values.
Junior Subordinated Debt Securities
The interest rate on the variable rate junior subordinated debt securities is reset quarterly; therefore, the carrying values approximate their fair values.

We evaluate securities with unrealized losses quarterly to determine if the decline in fair value has resulted from credit losses or other factors. There were 1197 debt securities in an unrealized loss position at June 30, 2021March 31, 2022 and 3 debt securities in an unrealized loss position31 at December 31, 2020.2021. 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. The unrealized losses on the debt securities were attributable to changes in interest rates and not related to the credit quality of the issuers. All debt securities were determined to be investment grade and paying principal and interest according to the contractual terms of the security.

Consolidated Balance Sheets.
Commercial and industrial loans, or C&I, included $336.1$41.9 million of loans originated under the Paycheck Protection Program, or PPP, at June 30, 2021March 31, 2022 compared to $465.0$88.3 million at December 31, 2020.2021. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security, or CARES Act was signed into law. The CARES Act included the PPP, a program designed to aid small and medium sized businesses through federally guaranteed loans distributed through banks. PPP loans are forgivable, in whole or in part, if the proceeds are used for payroll and other permitted expenses in accordance with the requirements of the PPP. The loans are 100 percent guaranteed by the Small Business Administration, or SBA. These loans carry a fixed rate of 1.00 percent and a term of two years, or five years for loans approved by the SBA, on or after June 5, 2020. Payments are deferred for at least six months of the loan. The SBA pays us a processing fee ranging from 1 percent to 5 percent based on the size of the loan. Interest is accrued as earned and loan origination fees and direct costs are deferred and accreted or amortized into interest income over the life of the loan using the level yield method. When a PPP loan is paid off or forgiven by the SBA, the remaining unaccreted or unamortized net origination fees or costs will be immediately recognized into income.
At June 30, 2021, ourOur business banking segment was $1.1 billion compared to $1.2 billion at March 31, 2022 and December 31, 2020.2021. Business banking consists of commercial 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. Business banking consisted of $506.2$552.2 million of commercial real estate loans, $228.1$216.7 million of C&I loans $10.3of which $20.6 million are PPP loans, $15.4 million of commercial construction loans $326.2and $357.0 million of consumer real estate loans and $0.03 million of other consumer loans that have a commercial purpose at June 30, 2021.March 31, 2022. At December 31, 20202021 business banking consisted of $453.0$546.1 million of commercial real estate loans, $394.9$215.4 million of C&I loans $8.2of which $39.7 million are PPP loans, $16.2 million of commercial construction loans and $303.9$357.9 million of consumer real estate loans that have a commercial purpose. During the first quarter of 2021, $90.2 million of commercial loans and $23.2 million of consumer loans were reclassified into the business banking segment.loans.
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 mitigate this risk by reviewing the relevant economic indicators and internal risk rating trends and through stress testing of the loans in these segments.segments to determine if additional ACL is needed. Total commercial loans represented 78.576.6 percent of total portfolio loans at both June 30, 2021 andMarch 31, 2022 compared to 77.2 percent at December 31, 2020.2021. Within our commercial portfolio, the CRE and commercial construction portfolios combined comprised $3.7 billion, or 67.768.6 percent, of total commercial loans at June 30, 2021 and $3.7 billion, or 65.6 percent, of total commercial loans at December 31, 2020 and 53.252.5 percent of total portfolio loans at June 30, 2021March 31, 2022 and 51.5$3.7 billion, or 68.0 percent, of total commercial loans and 52.5 percent of total portfolio loans at December 31, 2020.2021.
We lend primarily in Pennsylvania and the contiguous states of Ohio, New York, West Virginia and Maryland. The majority of our commercial and consumer loans are made to businesses and individuals in this geography, resulting in a concentration. We believe our knowledge and familiarity with customers and conditions locally outweighs this geographic concentration risk. The conditions of the local and regional economies are monitored closely through publicly available data and information supplied by our customers. We also use subscription services for additional geographic and industry specific information. Our CRE and commercial construction portfolios have exposure outside of this geography of 6.1 percent of the combined portfolios and 3.2 percent of total portfolio loans at March 31, 2022. This compares to 5.7 percent of the combined portfolios and 3.0 percent of total portfolio loans at December 31, 2021.

We also use subscription services for additional geographic and industry specific information. Our CRE and commercial construction portfolios have exposure outside of this geography of 5.4 percent of the combined portfolios and 2.9 percent of total portfolio loans at June 30, 2021. This compares to 5.9 percent of the combined portfolios and 3.0 percent of total portfolio loans at December 31, 2020.
We individually evaluate all substandard and nonaccrual commercial loans that have experienced a forbearance or change in terms agreement, and all substandard consumer and residential mortgage loans that entered into an agreement to modify their existing loan, to determine if they should be designated as troubled debt restructurings, or TDRs.
All TDRs will be reported as such for the remaining life of the loan, unless the restructuring agreement specifies an interest rate equal to or greater than the rate that would be accepted at the time of the restructuring for a new loan with comparable risk and it is fully expected that the remaining principal and interest will be collected according to the restructured agreement. TDRs can be returned to accruing status if the ultimate collectability of all contractual amounts due, according to the restructured agreement, is not in doubt and there is a period of a minimum of six months of satisfactory payment performance by the borrower either immediately before or after the restructuring.
The following tables summarize restructured loansTDRs as of the dates presented:

In response to the coronavirus, or COVID-19, pandemic and its economic impact on our customers, we implemented a short-term modification program that complies with the CARES Act to provide temporary payment relief to those borrowers directly impacted by the pandemic who were not more than 30 days past due as of December 31, 2019. This program allows for a deferral of payments for 90 days and up to a maximum of 180 days for our commercial customers. The customer remains responsible for deferred payments along with any additional interest accrued during the deferral period. Under the applicable guidance, none of these loans were considered restructured as of June 30, 2021. We had 42 commercial loans that were modified totaling $68.7 million at June 30, 2021 compared to 52 commercial loans that were modified totaling $195.6 million at December 31, 2020.

NOTE 6. 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 the risk of these loans is 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 home equity loans, home equity lines of credit and 1-4 family residential mortgages, including purchase money mortgages. 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.lines and credits cards. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.
Management monitors various credit quality indicators for the commercial, business banking and consumer loan portfolios, including changes in risk ratings, nonperforming status and delinquency on a monthly basis.
We monitor the commercial 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.

We monitor the delinquent status of the commercial and consumer portfolios on a monthly basis. Loans are considered nonperforming 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 nonperforming loans.

(1) We had 423 loans that were modified totaling $68.7$12.5 million under the CARES Act at June 30, 2021.March 31, 2022. These customers were not considered past due as a result of their delayed payments. Upon exiting the loan modification deferral program, the measurement of loan delinquency will resume where it left off upon entry into the program. Due to the modifications, this delinquency table may not accurately reflect the credit risk associated with these loans.
(2) We had 5 loans that were originated under the PPP program totaling $1.1 million at March 31, 2022 that were 90 days or greater past due. These loans were in process of forgiveness and were not considered as nonperforming loans due to the terms of the SBA guarantee.

The adoptionC&I portfolio included $41.9 million of ASU 2016-13 resulted in an increase to our ACL of $27.4 million on January 1, 2020. The increase included $8.2 million for S&T legacy loans and $9.3 million for acquired loans fromoriginated under the DNB merger. We also recorded a day one adjustment of $9.9 million primarily related to a C&I relationship that was charged off in the first quarter of 2020. We obtained information on the relationship subsequent to filing our DecemberPPP program at March 31, 2019 Form 10-K, but before the end of the first quarter of 2020. The updated information supported a loss existed at January 1, 2020.
The provision for credit losses, which includes a provision for losses on loans and on unfunded commitments, is a charge to earnings to maintain the ACL at a level consistent with management's assessment of expected losses in the loan portfolio at the balance sheet date. The provision for credit losses decreased $84.2 million and $101.1 million to $2.6 million and $5.7 million for the three and six months ended June 30, 20212022 compared to $86.8 million and $106.8$499.1 million for the same periodsperiod in 2020. The provision for credit losses includes $0.6 million and $0.4 million for2021.The loans are 100 percent guaranteed by the reserve for unfunded commitments for the three and six months ended June 30, 2021.
During the three months ended June 30, 2020,SBA, therefore, we recognized a charge-off of $58.7 million related to a customer fraud from a check kiting scheme. We continue to pursue all available resources of recovery to mitigate the loss. The customer also had a lending relationship of $15.1 million that had a $4.2 million charge-off during the three months ended June 30, 2020. We received a recovery of $0.9 million on the lending relationship during the three months ended June 30, 2021.
The significant decrease in the provision for credit losses during the three and six months ended June 30, 2021 was mainly due to the above mentioned customer fraud and an improved economic forecast in 2021 compared to 2020. Our economic forecast covers a period of two years and is driven primarily by national unemployment data. The forecasted national unemployment rate improved at June 30, 2021 compared to the same periods in 2020.

NOTE 7. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES
Derivatives Not Designated as Hedging Instruments
Interest Rate SwapsContracts with Customers
In accordance with applicable accounting guidance for derivatives and hedging, all derivatives are recognized as either assets or liabilities on the balance sheet at fair value. Interest rate swaps with customers are contracts in which a series of interest ratecash flows (fixed and variable) are exchanged over a prescribed period. The notional amounts on which the interest payments are based are not exchanged. These derivative positions relate to transactions in which we enter into an interest rate swap with a commercial customer while at the same time entering into an offsetting interest rate swap with another financial institution. In connection with each transaction, we agree to pay interest to the customer on a notional amount at a variable interest rate and receive interest from the customer on the same notional amount at a fixed rate. At the same time, we agree to pay another financial institution the same fixed interest rate on the same notional amount and receive the same variable interest rate on the same notional amount. The transaction allows our customer to effectively convert a variable rate loan to a fixed rate loan with us receiving a variable rate. These agreements could have floors or caps on the contracted interest rates.
Pursuant to our agreements with various financial institutions, we may receive collateral or may be required to post collateral based upon mark-to-market positions. Beyond unsecured threshold levels, collateral in the form of cash or securities may be made available to counterparties of interest rate swap transactions. Our current collateral requirements do not have a material effect on our cash flow or liquidity position.
Derivatives contain an element of credit risk, the possibility that we will incur a loss because a counterparty, which may be a financial institution or a customer, fails to meet its contractual obligations. All derivative contracts with financial institutions may be executed only with counterparties approved by our Asset and Liability Committee, or ALCO, and derivatives with customers may only be executed with customers within credit exposure limits approved by our Senior Loan Committee. Interest rate swaps with customers are considered derivatives but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives are recorded in current earnings and included in other noninterest income in the Condensed Consolidated Statements of Comprehensive Income.Income (Loss).
Interest Rate Lock Commitments and Forward Sale Contracts
In the normal course of business, we sell originated mortgage loans into the secondary mortgage loan market. We also offer interest rate lock commitments to potential borrowers. The commitments are generally for a period of 60 days and guarantee a specified interest rate for a loan if underwriting standards are met, but the commitment does not obligate the potential borrower to close on the loan. Accordingly, some commitments expire prior to becoming loans. We may encounter pricing risks if interest rates increase significantly before the loan can be closed and sold. We may utilize forward sale contracts in order to mitigate this pricing risk. Whenever a customer desires these products, a mortgage originator quotes a secondary market rate guaranteed for that day by the investor. The rate lock is executed between the mortgagee and us and in turn a forward sale contract may be executed between us and the investor. Both the rate lock commitment and the corresponding forward sale contract for each customer are considered derivatives but are not accounted for using hedge accounting. As such, changes in the estimated fair value of the derivatives during the commitment period are recorded in current earnings and included in mortgage banking in the Condensed Consolidated Statements of Comprehensive Income.Income (Loss).
Derivatives Designated as Hedging Instruments
Cash Flow Hedges of Interest Rate Risk
As part of our interest rate risk management strategy, we use interest rate swaps to add stability to interest income and to manage exposure to interest rate movements. Interest rate swaps designated as cash flow hedges involve the receipt of fixed-rate amounts from a counterparty in exchange for making variable rate payments over the life of the agreements without exchange of the underlying notional amount.
During the three months ended March 31, 2022, we entered into 4 interest rate swaps designated as cash flow hedges to hedge the variable cash flows associated with existing variable-rate assets. These contacts each have a notional value of $50.0 million and extend out over the next five years.
For designated derivatives that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and subsequently reclassified into interest income in the same period during which the hedged transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest income as interest payments are received on variable rate assets. During the next twelve months, we estimate that an additional $0.6 million will be reclassified as an increase to interest income.

NOTE 8. COMMITMENTS AND CONTINGENCIES
Commitments
In the normal course of business, we offer off-balance sheet credit arrangements to enable our customers to meet their financing objectives. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated financial statements. Our exposure to credit loss, in the event the customer does not satisfy the terms of the agreement, equals the contractual amount of the obligation less the value of any collateral. We apply the same credit policies in making commitments and standby letters of credit that are used for the underwriting of loans to customers. Commitments generally have fixed expiration dates, annual renewals or other termination clauses and may require payment of a fee. Because many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements.
Estimates of the fair value of these off-balance sheet items were not made because of the short-term nature of these arrangements and the credit standing of the counterparties.
The following table sets forth our commitments and letters of credit as of the dates presented:

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.Income (Loss). The allowance for unfunded commitments is included in other liabilities in the Consolidated Balance Sheets.

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

NOTE 10. EMPLOYEE BENEFITS

Our qualified and nonqualified defined benefit plans were amended to freeze benefit accruals for all persons entitled to benefits under the plans in 2016. We will continue recording pension expense related to these plans, primarily representing interest costs on the projected benefit obligation and amortization of actuarial losses accumulated in the plans, as well as income from expected investment returns on pension assets. Since the plans have been frozen, 0 service costs are included in net periodic pension expense.
The investment policy for S&T's defined benefit plan is 90 percent fixed income and 10 percent equity and cash. The expected long-term rate of return on plan assets is 2.42 percent as of June 30, 2021 compared to 3.45 percent for the same period in 2020.
We remeasured our pension obligation and recognized a pension settlement charge of $0.2 million and $0.9 million for the three and six months ended June 30, 2021. A settlement charge is incurred when the aggregate amount of lump-sum distributions during the year is greater than the sum of the interest cost component of the annual net periodic pension cost.
The following table summarizes the components of net periodic pension cost for the periods presented:

NOTE 11. SHARE REPURCHASE PLAN

On March 15, 2021, our Board of Directors authorized an extension of its $50 million share repurchase plan, which was set to expire March 31, 2021. This authorization extended the expiration date of the repurchase plan through March 31, 2022. The plan permits S&T to repurchase from time to time up to the previously authorized $50 million in aggregate value of shares of S&T's common stock, with $37.4 million of capacity remaining at June 30, 2021, 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. During the three and six months ended June 30, 2021, we had 0 repurchases. Repurchase activity was suspended in March of 2020 due to the impact of the COVID-19 pandemic. During the year ended December 31, 2020, we repurchased 411,430 common shares at a total cost of $12.6 million, or an average of $30.52 per share.

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 at and for the three and six month periods ended June 30, 2021March 31, 2022 and 2020.2021. 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-lookingForward looking statements are typically identified by words or phrases such as “will likely result”, “expect”, “anticipate”, “estimate”, “forecast”, “project”, “intend”, “ believe”“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; cyber-securitylosses, 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 including a prolonged period of low interest rates, 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; changes in accounting policies, practices, or guidance, for example, our adoption of CECL;guidance; legislation affecting the financial services industry as a whole, and S&T, in particular; climate change and related legislative and regulatory initiatives; 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 including DNB, 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;employees, particularly in light of the strong competition in the marketplace; our ability to successfully manage our CEO transition; general economic or business conditions, including the strength of regional economic conditions in our market area; macroeconomic conditions including inflation and economic uncertainty; the duration and severity of the coronavirus, (“COVID-19”)or COVID-19 pandemic, both in our principal area of operations and nationally, including the ultimate impact of the pandemic on the economy generally and on our operations; our participation in the Paycheck Protection Program; 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 Annual Report on Form 10-K for the year ended December 31, 2020,2021, including Part I,II, Item 1A-"1A, Risk Factors"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 involving significant judgments and assumptions used in the preparation of the Consolidated Financial Statementsestimates as of June 30, 2021March 31, 2022 remained unchanged from the disclosures presented in our Annual Report on Form 10-K for the year ended December 31, 20202021 under Part II, Item 7 - “Management’s Discussion and Analysis of Financial Condition and Results of Operations”.Operations.”

COVID-19 Update

The extent to which the COVID-19 pandemic may adversely impact our business depends on future developments, which remain highly uncertain and unpredictable. The pandemic has had, and we expect that it will continue to have, negative impacts on S&T’s commercial and consumer loan customers and the economy as a whole. The severity and length of the pandemic’s impact on S&T and the U.S. and global economies continue to be unknown.
As we navigate through the uncertainty resulting from the pandemic, our first priority remains the safety of both our employees and customers. Our financial performance continues to be negatively impacted in many ways due to the pandemic. We are closely monitoring our asset quality with a focus on the loan portfolios that have been significantly impacted by the pandemic, including our hotel portfolio. We did experience some improvement in our asset quality during the three and six months ended June 30, 2021, but remain cautious given the current environment. Our balance sheet is asset sensitive resulting in our net interest income and net interest margin, or NIM, being negatively impacted in this low interest rate environment. Our net interest income is also being impacted by declining loan balances as new loan originations have decreased in the current environment. Partially offsetting this impact was the Paycheck Protection Program, or PPP. Net interest income was favorably impacted by PPP loans which contributed $4.1 million and $9.9 million for the three and six months ended June 30, 2021 to interest income.

Earnings Summary
We recognized net income of $28.4$29.1 million, or $0.72 per diluted share and $60.3 million, or $1.54$0.74 per diluted share for the three and six months ended June 30, 2021March 31, 2022 compared to a net lossincome of ($33.1)$31.9 million, or ($0.85) per diluted share and ($19.8) million, or ($0.51)$0.81 per diluted share for the same periodsperiod in 2020.2021. The increase$2.8 million decrease in net income for the three and six months ended June 30, 2021March 31, 2022 was primarily due to significant decreasedecreases in net interest income of $84.2$2.9 million and $101.1noninterest income of $2.0 million and increases in noninterest expenses of $1.8 million offset by a significant decrease in our provision for credit losses of $3.6 million compared to the same periodsperiod in 2020.2021.
Net interest income decreased $2.9 million to $67.7 million for the three months ended March 31, 2022 compared to $70.6 million during the same period in 2021. The decline was primarily due to reduced PPP revenue of $4.1 million compared to the prior period. The net interest margin, or NIM, on an FTE basis (non-GAAP) decreased 31 basis points for the three months ended March 31, 2022 compared to the same period in 2021. Increased interest-bearing deposits with banks negatively impacted the net interest margin on an FTE basis (non-GAAP) by 16 basis points and reduced revenue from PPP loans negatively impacted the net interest margin on an FTE basis (non-GAAP) by 4 basis points for the three months ended March 31, 2022 compared to the prior period.
The provision for credit losses, which includes a provision for losses on loans and on unfunded commitments, decreased $3.6 million to a negative $0.5 million for the three months ended March 31, 2022 compared to $3.1 million for the same period in 2021. The significant decrease in the provision for credit losses during the three and six months ended June 30, 2021March 31, 2022 was mainly due to a $2.5 million recovery on a C&I relationship during the first quarter of 2022 and improvement in economic conditions resulting in declines in our criticized and classified assets and nonperforming loans.
Noninterest income decreased $2.0 million for the three months ended March 31, 2022 compared to the same period in 2021. The decrease in noninterest income primarily related to a decrease of $3.3 million in mortgage banking due to a lower volume of loans originated for sale in the secondary market. Partially offsetting this decrease was higher debit and credit card fees of $0.9 million and service charges on deposit accounts of $0.5 million due to the improving economic environment resulting in increased customer fraudactivity.
Noninterest expense increased $1.8 million to $47.4 million for the three months ended March 31, 2022 compared to $45.6 million for the same periods in 2020 that resulted2021.

Net interest income decreased $1.8incentive increases partially offset by lower pension and medical expense. Other noninterest expense increased $0.6 million and $1.2 million to $68.3 million and $139.0 million for the three and six months ended June 30, 2021 compared to $70.1 million and $140.2 million in 2020. The decrease in net interest income was primarilymainly due to lower short-term interest rates and a decrease in average loan balances of $537.6 million and $239.7 million for the three and six months ended June 30, 2021higher other real estate owned, or OREO, expense compared to the same periods in 2020. Average interest-bearing deposits decreased $186.4 million and $174.6 million for the three and six months ended June 30, 2021 compared to the same periods in 2020. Our net interest margin on an FTE basis (non-GAAP) decreased to 3.16 percent and 3.31 percent for the three and six months ended June 30, 2021 compared to 3.31 percent and 3.42 percent for the same periods in 2020 primarily due to lower short-term interest rates and higher interest bearing deposits with banks. Net interest margin is reconciled to net interest income adjusted to an FTE basis in the "Net Interest Income" section of this MD&A.
The provision for credit losses, which includes a provision for losses on loans and on unfunded commitments, decreased $84.2 million and $101.1 million to $2.6 million and $5.7 million for the three and six months ended June 30, 2021 compared to $86.8 million and $106.8 million for the same periods in 2020. The significant decrease in the provision for credit losses during the three and six months ended June 30, 2021 was mainly due to a customer fraud in 2020 and an improved economic forecast in 2021 compared to 2020.
Noninterest income increased $0.2 million and $5.0 million for the three and six months ended June 30, 2021 compared to the same periods in 2020. Debit and credit card and service charges on deposit accounts increased in both the three and six months ended June 30, 2021 as customer activity has increased in the improving economic environment. Wealth management income increased in both periods due to higher assets under management from market appreciation and an increase in customer activity. Partially offsetting these increases was a decrease in commercial loan swap income due to lower activity as a result of the pandemic and interest rate environment.
Noninterest expense increased $2.4 million and $1.5 million to $45.8 million and $91.4 million for the three and six months ended June 30, 2021 compared to $43.5 million and $89.9 million for the same periods in 2020. The higher noninterest expense was mainly due to increases of $3.1 million and $5.1 million of salaries and employee benefits for the three and six months ended June 30, 2021. The increase for the six month period was offset by $2.3 million of merger-related expenses recognized in the six months ended June 30, 2020 compared to no merger-related expenses in 2021.
The provision for income taxes increased $18.8 million and $23.3decreased $0.4 million to $7.0 million and $14.2$6.9 million for the three and six months ended June 30, 2021March 31, 2022 compared to $7.3 million for the same periodsperiod in 2020.2021. The increasedecrease in income tax expense was primarily due to the tax benefit from the net loss noted above duringdecrease in pretax income of $3.1 million compared to the same periodsperiod in 2020.2021. Our effective tax rate was 19.7 percent and 19.119.2 percent for the three and six months ended June 30, 2021March 31, 2022 compared to 26.3 percent and 31.318.6 percent for the same period in 2020.2021. The change in our effective tax rate for the three and six months ended June 30, 2021March 31, 2022 was primarily due to the increasesdecreased tax benefits associated with low income housing tax credits in pretax income2022 compared to pretax losses in 2020.2021.
Explanation of Use of Non-GAAP Financial Measures
In addition to the results of operations presented in accordance with generally accepted accounting principles, or GAAP, in the United States, management uses, and this quarterly report references, net interest income and net interest margin, each on a fully taxable equivalent, or FTE, basis, which are non-GAAP financial measures. Management believes net interest income and net interest margin on an FTE basis 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 management believes 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.
We believe the presentation of net interest income and net interest margin on an FTE basis ensures the comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice. Interest income (GAAP) per the Condensed Consolidated Statements of Comprehensive Income (Loss) is reconciled to net interest income adjusted on an FTE basis and net interest margin adjusted on an FTE basis in the "Results of Operations - Three and Six Months Ended June 30, 2021March 31, 2022 Compared to Three and Six Months Ended June 30, 2020March 31, 2021 - Net Interest Income" section of this MD&A.

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.
The interest income on interest-earning assets and the net interest margin are presented on an FTE basis. The FTE basis 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 and the dividend-received deduction for equity securities.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.

Provision for Credit Losses
The provision for credit losses, which includes a provision for losses on loans and on unfunded commitments, is a charge to earnings to maintain the ACL at a level consistent with management's assessment of expected credit losses in the loan portfolio at the balance sheet date. The provision for credit losses decreased $84.2 million and $101.1$3.6 million to $2.6 million and $5.7a negative $0.5 million for the three and six months ended June 30, 2021March 31, 2022 compared to $86.8 million and $106.8$3.1 million for the same periodsperiod in 2020. The provision for credit losses included $0.6 million and $0.4 million for the reserve for unfunded commitments for the three and six months ended June 30, 2021.
The significant decrease in the provision for credit losses duringof $3.6 million for the three and six months ended June 30, 2021 was mainly due to the customer fraud in 2020 discussed below and an improved economic forecast in 2021 compared to 2020. Our economic forecast covers a period of two years and is driven primarily by national unemployment data. The forecasted national unemployment rate improved at June 30, 2021March 31, 2022 compared to the same timeperiod in 2020.2021 was primarily due to a $2.5 million recovery on a C&I relationship during the first quarter of 2022 and improvement in economic conditions resulting in an improved forecast and declines in our criticized and classified assets and nonperforming loans.
ForNet loan recoveries were $2.0 million for the three and six months ended June 30, 2021, we hadMarch 31, 2022 compared to net loan charge-offs of $7.4 million and $13.3 million compared to $68.1 million and $79.2$5.8 million for the same periodsperiod in 2020.2021. The most significant charge-offnet recoveries were primarily due to the above mentioned recovery that occurred during the first quarter of 2022.

ended June 30, 2021 was a $4.9 million charge-off related to a CRE relationship. Our policy is to obtain appraisals annually on loans individually assessed for impairment. The $4.9 million charge-off was a result of the receipt of the annual appraisal which evidenced a deterioration in the value of the collateral at June 30, 2021.
During the three months ended June 30, 2020, we recognized a charge-off of $58.7 million related to a customer fraud from a check kiting scheme. We continue to pursue all available resources of recovery to mitigate the loss. The customer also had a lending relationship of $15.1 million that had a $4.2 million charge-off during the three months ended June 30, 2020. We received a recovery of $0.9 million on the lending relationship during the three months ended June 30, 2021.
Nonperforming loans increased $22.5 million to $112.6 million at June 30, 2021 compared to $90.1 million at June 30, 2020. The increase in nonperforming loans primarily related to the addition of $48.7 million of hotel loans which moved to nonperforming during the fourth quarter of 2020 as a result of continued deterioration due to the pandemic. The increase was partially offset by the $4.9 million charge-off of the CRE relationship mentioned above and payoffs of three commercial relationships totaling approximately $12.6 million, all of which occurred during the three months ended June 30, 2021.

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 decreased $36.1 million to $7.0 billion at March 31, 2022 compared to December 31, 2021. Portfolio loans excluding PPP loans increased $10.3 million compared to December 31, 2021.

These loans carry a fixed rate of 1.001 percent and a term of two years, or five years for loans approved by the SBA on or after June 5, 2020. Payments are deferred for the first six months of the loan. The loans are 100 percent guaranteed by the SBA. The SBA pays us a processing fee ranging from 1 percent to 5 percent based on the size of the loan.
Consumer loans represent 21.523.4 percent of our total portfolio loans at June 30, 2021March 31, 2022 and 22.8 percent at December 31, 2020.2021.

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 Refer to Part 1. Financial Information, Note 6. Allowance for Credit Losses for details on our 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 healthcare. 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 ofsegments.

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 the risk of these loans is 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 businessesthat 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 home equity loans, home equity lines of credit and 1-4 family residential mortgages, including purchase money mortgages. 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. 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.

The ACL was $99.9 million, or 1.43 percent of total portfolio loans, decreased 7 basis points to 1.56 percent at June 30, 2021March 31, 2022 compared to 1.63$98.6 million, or 1.41 percent at December 31, 2020. The ACL excluding PPP loans as a percentage of total portfolio loans, was 1.64 percent as of June 30, 2021 compared to 1.74 percent at December 31, 2020.2021. The increase in the ACL of $1.3 million was due to a $2.7 million increase in specific reserves on loans individually assessed and a $2.0 million increase in the overall qualitative reserve. The increase in specific reserves on loans individually assessed was due to a $2.7 million increase for a C&I relationship due to continued market deterioration in the estimated enterprise value of the company. The increase in the overall qualitative reserve was the result of additional segment allocations made in our healthcare and C&I portfolios due to continued uncertainty related to the COVID-19 variant and an increase in our economic forecast due primarily to concerns with rising inflation and macroeconomic conditions. Offsetting this increase was a $3.4 million decrease in the quantitative reserve due primarily to improving trends in our hotel portfolio.
Net loan charge-offsrecoveries were $7.4$2.0 million, or 0.43(0.12) percent of average loans and $13.3 million, or 0.37 percentannualized as a percentage of average loans, for the three and six months ended June 30, 2021.March 31, 2022. The most significant charge-off for the three and six months ending June 30, 2021 was a $4.9 million charge-offnet recoveries primarily related to a CRE relationship. Our policy is to obtain appraisals annually$2.5 million recovery on loans individually assessed for impairment. The $4.9 million charge-off was a resultC&I relationship during the first quarter of the receipt of the annual appraisal which evidenced a deterioration in the value of the collateral at June 30, 2021.2022.

The decrease in substandard loans was primarily due to $19.7 million of loan upgrades in our hotel portfolio and $12.0 million of various loan payoffs and pay downs. The decrease in substandard loans was partially offset by the payoffs of two CRE relationships of $5.3 million and $4.5 million and the above noted charge-offaddition of a $4.9$10.5 million CRE relationship.relationship, which was downgraded to substandard due to financial deterioration that led to cash flow shortfalls. Special mention loans decreased $24.5 million to $167.8 million at March 31, 2022 compared to $192.3 million at December 31, 2021. The decrease in special mention loans was primarily due to the downgradeupgrade of a $11.9 million CRE relationship from special mention to substandard due to declining revenue that led to cash flow shortfalls.three hotel relationships totaling $21.4 million.
Troubled debt restructurings, or TDRs, decreased $11.8$5.6 million to $34.9$26.1 million at June 30, 2021March 31, 2022 compared to $46.7$31.7 million at December 31, 2020.2021. The decrease in TDRs was primarily due to payoffs of $4.5 million and $3.7 million CRE relationships and a charge-offthe payoff of a $4.9$4.2 million CRE relationship.C&I relationship and other loan pay downs. Total TDRs of $34.9$26.1 million at June 30, 2021 included $14.3$10.7 million, or 41.0 percent, that were accruingperforming and $20.6$15.4 million, or 59.0 percent, that were not accruing.nonperforming at March 31, 2022.
Our allowance for credit losses on unfunded commercial lending 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.Income (Loss). The allowance for unfunded loan commitments was $4.9increased $0.2 million to $5.4 million at June 30, 2021March 31, 2022 compared to $4.5$5.2 million at December 31, 2020.2021. This change was primarily due to higher loss rates in the construction portfolio. The allowance for unfunded commitments is included in other liabilities in the Consolidated Balance Sheets.

Item 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
Liquidity and Capital Resources
Liquidity is defined as a financial institution’s ability to meet its cash and collateral obligations at a reasonable cost. This includesOur 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.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 sources. Refer to the "Financial Condition-Deposits"Condition as of March 31, 2022-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 when either a structure or cost efficiency has been identified. 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, the brokered deposit market and borrowing availability through the Federal Reserve Borrower-In-Custody program.
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 June 30, 2021,March 31, 2022, we had $1.4$1.3 billion in highly liquid assets, which consisted of $897.5$750.9 million in interest-bearing deposits with banks, $459.3$585.4 million in unpledged securities, and $7.6$1.4 million in loans held for sale. This resulted in a highly liquid assets to total assets ratio of 14.414.2 percent at June 30, 2021.March 31, 2022. Also, at June 30, 2021,March 31, 2022, we had remaining borrowing availability of $2.5$2.6 billion with the FHLB of Pittsburgh. ReferFor more information regarding our outstanding borrowings refer to the "Financial Condition-Condition as of March 31, 2022- Borrowings" section of this MD&A for more details.

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 June 30, 2021,March 31, 2022, 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 Asset and Liability Committee, or 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. We have temporarily suspended the analyses on downward rate shocks of 200 basis points or more because they do not provide meaningful insight into our interest rate risk position.
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. We have also temporarily suspended the downward rate shocks of 200 basis points or more for EVE.
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 an improvement in the percentage change in pretax net interest income in the rates up scenarios and a decline in the rates down scenarios when comparing June 30, 2021March 31, 2022 to December 31, 2020.2021. We have become more asset sensitive due to the discontinuation of our increased balances at the Federal Reserve.indexed money market deposit product. Our EVE analyses show a decline in the percentage change in EVE in the rates up scenarios and an improvement in the rates down scenario when comparing June 30, 2021March 31, 2022 to December 31, 2020.2021. The EVE decline is due to the impact of a steepened yield curve on the value of non-maturity deposits.
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 Interim Chief Executive Officer, or CEO, and Chief Financial Officer, or CFO (its principal executive officer and principal financial officer, respectively), management has evaluated the effectiveness of the design and operation of S&T’s disclosure controls and procedures as of June 30, 2021.March 31, 2022. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Securities Exchange Act of 1934, as amended, or the Exchange Act, is recorded, processed, summarized and reported within the time periods required by the Securities and Exchange Commission, or the SEC, and that such information is accumulated and communicated to S&T’s management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure.
Based on and as of the date of such evaluation, our CEO and CFO concluded that the design and operation of our disclosure controls and procedures were effective in all material respects, as of the end of the period covered by this report.

Changes in Internal Control over Financial Reporting
During the quarter ended June 30, 2021,March 31, 2022, 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.

Item 1A. Risk Factors
There have been no material changes to the risk factors that we have previously disclosed in Part I, Item 1A – “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2020,2021, as filed with the SEC on March 1, 2021February 28, 2022 other than the risks described below.
Risks Related to Our Business Strategy
Our future performance will depend, in part, on the successful transition of our new CEO.
On October 2, 2020, we announced that Todd D. Brice will retire as Chief Executive Officer of S&T and S&T Bank, and as a member of the Boards of Directors of S&T and S&T Bank, effective March 31, 2021. On July 12, 2021 we announced that Christopher J. McComish will be appointed Chief Executive Officer (CEO) of S&T and S&T Bank, effective August 23, 2021 (the “Effective Date”) and will also be appointed to the Boards of Directors of S&T and S&T Bank on the Effective Date. From and following the Effective Date, David G. Antolik, who has served as Interim Chief Executive Officer since April 2021, will continue as President of S&T and S&T Bank and as a member of the Boards of Directors of S&T and S&T Bank. Our future performance will depend, in part, on the successful transition of our new CEO. This transition may be disruptive to our business, and if we are unable to execute an orderly transition and successfully integrate our new CEO into our management team, our revenue, results of operations, and financial condition may be adversely affected. Further, if our new CEO formulates different or changed views, the future strategy and plans of S&T may differ materially from those of the past.

Item 1A. Risk Factors - continued
Russia’s invasion of Ukraine 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 are experiencing volatility and disruption following the start 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. Furthermore, continued increases in commodity prices contributing to higher inflation could negatively impact our customers and 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. Although the extent and duration of the military action or future escalation of such hostilities, the extent and impact of existing and future sanctions, 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.

(1) On March 15, 2021,21, 2022, our Board of Directors authorized an extension of the $50 million share repurchase plan, which was set to expire March 31, 2021.2022. This authorization extended the expiration date of the repurchase plan through March 31, 2022.2023. The plan permits S&T to repurchase from time to time up to the previously authorized $50 million in aggregate value of shares of S&T's common stock, with $37.4 million of capacity remaining at June 30, 2021,March 31, 2022, 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.
