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, 2021, filed with the Securities and Exchange Commission, or SEC, on February 28, 2022 (2021 Form 10-K). In the opinion of management, the accompanying interim financial information reflects all adjustments, consisting of normal recurring adjustments, necessary to present fairly our financial position and the results of operations for each of the interim periods presented. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year or any future period.

Reclassification

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.

Accounting Policy for Derivative Instruments and Hedging Activities

During the six months ended June 30, 2022, we entered into 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 2021 Form 10-K for a discussion of our complete Accounting Policy for Derivative Instruments and Hedging Activities.

Recently Adopted Accounting Standards Updates, or ASU or Updated

Reference Rate Reform (Topic 848) Facilitation of the Effects of Reference Rate Reform on Financial Reporting

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. The amendments in this ASU 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. 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

Financial Instruments Credit Losses (Topic 326) Troubled Debt Restructurings and Vintage Disclosures

In March 2022, the FASB issued ASU 2022-02, Financial Instruments Credit Losses (Topic 326): Troubled Debt Restructuring and Vintage Disclosures. The guidance eliminates the “once a TDR, always a TDR” requirement for loan disclosures and requires disclosures about the performance of modified loans to borrowers experiencing financial difficulty in the 12 months following the modification.

The amendments eliminate the recognition and measurement guidance related to TDRs for creditors that have adopted ASC 326 Financial Instruments - Credit Losses. We adopted ASU 2016-13 Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, on January 1, 2020. 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. Early adoption is permitted, however, we have not elected to do so. We are currently evaluating the impact of this ASU which will require new disclosures, but we do not expect it to have a material impact on our consolidated financial statements.

The two-class method was used to determine earnings per share for the three and six months ended June 30, 2022 and 2021. The following table reconciles the numerators and denominators of basic and diluted earnings per share calculations for the periods presented:

Three months ended June 30, Six months ended June 30,
(in thousands, except share and per share data) 2022 2021 2022 2021
Numerator for Earnings per Share—Basic and Diluted:

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.

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 124 debt securities in an unrealized loss position at June 30, 2022 and 31 debt securities in an unrealized loss position at December 31, 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.

Commercial and industrial loans, or C&I, included $11.7 million of loans originated under the Paycheck Protection Program, or PPP, at June 30, 2022 compared to $88.3 million at December 31, 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.

Our business banking segment was $1.2 billion at June 30, 2022 compared to $1.1 billion at December 31, 2021. Business banking consists of 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. Business banking consisted of $565.7 million of commercial real estate loans, $217.9 million of C&I loans of which $11.7 million are PPP loans, $15.1 million of commercial construction loans and $364.6 million of loans secured by consumer real estate at June 30, 2022. At December 31, 2021 business banking consisted of $546.1 million of commercial real estate loans, $215.4 million of C&I loans of which $39.7 million are PPP loans, $16.2 million of commercial construction loans and $357.9 million of loans secured by consumer real estate.

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 to determine if additional ACL is needed. Total commercial loans represented 75.2 percent of total portfolio loans at June 30, 2022 compared to 77.2 percent at December 31, 2021. Within our commercial portfolio, the CRE and commercial construction portfolios combined comprised $3.6 billion, or 68.0 percent, of total commercial loans and 51.2 percent of total portfolio loans at June 30, 2022 and $3.7 billion, or 68.0 percent, of total commercial loans and 52.5 percent of total portfolio loans at December 31, 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 6.4 percent of the combined portfolios and 3.3 percent of total portfolio loans at June 30, 2022. This compares to 5.7 percent of the combined portfolios and 3.0 percent of total portfolio loans at December 31, 2021.

We evaluate all substandard commercial, consumer and residential mortgage loans that have experienced a forbearance or change in terms to modify their existing loan to determine if they should be designated as troubled debt restructurings, or TDRs.

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.

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 and unsecured loans and lines of credit. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.

NOTE 6. ALLOWANCE FOR CREDIT LOSSES – continued

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 and placed on nonaccrual when interest and principal are 90 days or more past due or management has determined that a material deterioration in the borrower’s financial condition exists. The risk of loss is generally highest for nonperforming loans.

The following tables present loan balances by year of origination and performing and nonperforming status for our portfolio segments as of the dates presented:

NOTE 7. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

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.

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 $2.3 million will be reclassified as a decrease to interest income.

NOTE 7. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES – continued

Derivatives Not Designated as Hedging Instruments

Interest Rate Contracts with Customers

Interest rate swaps with customers are contracts in which a series of cash 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.

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 (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 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 (Loss).

The following table indicates the amounts representing the value of derivative assets and derivative liabilities for the dates presented:

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:

(dollars in thousands) June 30, 2022 December 31, 2021
Commitments to extend credit $ 2,600,322 $ 2,583,957
Standby letters of credit 80,665 87,335
Total $ 2,680,987 $ 2,671,292

Allowance for Credit Losses on Unfunded Loan Commitments

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

The following table presents activity in the allowance for credit losses on unfunded loan commitments as of the dates presented:

Three months ended June 30, Six months ended June 30,
(dollars in thousands) 2022 2021 2022 2021

Provision for credit losses 2,012 555 2,198 391
Total $ 7,387 $ 4,858 $ 7,387 $ 4,858

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. SHARE REPURCHASE PLAN

On March 21, 2022, our Board of Directors authorized an extension of its $50 million share repurchase plan, which was set to expire March 31, 2022. This authorization extended the expiration date of the repurchase plan through March 31, 2023. The plan permits S&T to repurchase shares up to the previously authorized $50 million in aggregate value of S&T's common stock through a combination of open market and privately negotiated repurchases. The specific timing, price and quantity of repurchases will be at the discretion of S&T and will depend on a variety of factors, including general market conditions, the trading price of common stock, legal and contractual requirements, applicable securities laws and S&T's financial performance. The repurchase plan does not obligate us to repurchase any particular number of shares. At June 30, 2022 there was $33.3 million of capacity remaining under the plan. 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, 2022, we repurchased 151,220 common shares under this plan at a total cost of $4.2 million, or an average of $27.46 per share. During the three and six months ended June 30, 2021 we had no repurchases.

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

Management’s Discussion and Analysis of Financial Condition and Results of Operations, or MD&A, represents an overview of our consolidated results of operations and financial condition and highlights material changes in our financial condition and results of operations for the three and six months ended June 30, 2022 and 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 looking statements are typically identified by words or phrases such as “will likely result,” “expect,” “anticipate,” “estimate,” “forecast,” “project,” “intend,,” “believe,” “assume,” “strategy,” “trend,” “plan,” “outlook,” “outcome,” “continue,” “remain,” “potential,” “opportunity,” “comfortable,” “current,” “position,” “maintain,” “sustain,” “seek,” “achieve” and variations of such words and similar expressions, or future or conditional verbs such as will, would, should, could or may. Although we believe the assumptions upon which these forward-looking statements are based are reasonable, any of these assumptions could prove to be inaccurate and the forward-looking statements based on these assumptions could be incorrect. The matters discussed in these forward-looking statements are subject to various risks, uncertainties and other factors that could cause actual results and trends to differ materially from those made, projected, or implied in or by the forward-looking statements depending on a variety of uncertainties or other factors including, but not limited to: credit losses and the credit risk of our commercial and consumer loan products; changes in the level of charge-offs and changes in estimates of the adequacy of the allowance for credit losses, or ACL; cyber security concerns; rapid technological developments and changes; operational risks or risk management failures by us or critical third parties, including fraud risk; our ability to manage our reputational risks; sensitivity to the interest rate environment 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; 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 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, 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, 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 2021 Form 10-K, including Part II, Item 1A, Risk Factors and any of our subsequent filings with the SEC. Forward-looking statements are based on beliefs and assumptions using information available at the time the statements are made. We caution you not to unduly rely on forward-looking statements because the assumptions, beliefs, expectations and projections about future events may, and often do, differ materially from actual results. Any forward-looking statement speaks only as to the date on which it is made, and we undertake no obligation to update any forward-looking statement to reflect developments occurring after the statement is made.

Critical Accounting Policies and Estimates

We view critical accounting policies to be those which are highly dependent on subjective or complex estimates, assumptions and judgments and where changes in those estimates and assumptions could have a significant impact on the Consolidated Financial Statements. Further, we view critical accounting estimates as those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial condition or results of operations. Our critical accounting policies and estimates as of June 30, 2022 remained unchanged from the disclosures presented in our 2021 Form 10-K under Part II, Item 7 - “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Earnings Summary

The following table presents a summary of key profitability metrics for the periods presented:

Three months ended June 30, Six months ended June 30,
2022 2021 2022 2021
Net Income $ 28,858 $ 28,367 $ 58,001 $ 60,268
Earnings Per Share - Diluted $ 0.74 $ 0.72 $ 1.48 $ 1.54
Return on average assets 1.25 % 1.21 % 1.25 % 1.31 %
Return on average shareholders' equity 9.83 % 9.65 % 9.85 % 10.39 %
Return on average tangible shareholders' equity (non-GAAP) 14.63 % 14.41 % 14.62 % 15.57 %

Net income increased $0.5 million for the three months ended June 30, 2022 compared to the same period in 2021 primarily due to an increase in net interest income of $6.9 million offset by a decrease in noninterest income of $2.8 million and an increase in noninterest expense of $2.6 million. Net income decreased $2.3 million for the six months ended June 30, 2022 compared to the same period in 2021 primarily due to a decrease in noninterest income of $4.9 million and an increase in noninterest expense of $4.3 million offset by an increase in net interest income of $4.0 million and a decrease in our provision for credit losses of $3.0 million.

Net interest income increased $6.9 million and $4.0 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. The net interest margin, or NIM, on an FTE basis (non-GAAP) increased 40 and 4 basis points for the three and six months ended June 30, 2022 compared to the same periods in 2021. The increases in net interest income and NIM on an FTE basis (non-GAAP) were primarily due to higher interest rates during 2022.

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

The provision for credit losses increased $0.6 million and decreased $3.0 million to $3.2 million and $2.7 million for the three and six months ended June 30, 2022 compared to $2.6 million and $5.7 million for the same periods in 2021.The increase in the provision for credit losses for the three months ended June 30, 2022 compared to the same period in 2021 was primarily due to an increase of $1.4 million in our provision for unfunded commitments related to higher construction commitments and expected loss rates in our construction portfolio. The decrease in the provision for credit losses for the six months ended June 30, 2022 compared to the same period in 2021 was due primarily to two large C&I loan recoveries totaling $6.6 million which were received during the six months ended June 30, 2022, and reductions in our quantitative reserve due primarily to significant improvement in our hotel portfolio.

Noninterest income decreased $2.8 million to $12.6 million for the three months ended June 30, 2022 and decreased $4.9 million to $27.9 million for the six months ended June 30, 2022 compared to the same periods in 2021. Mortgage banking decreased $1.3 million for the three months ended June 30, 2022 and decreased $4.6 million for the six months ended June 30, 2022. Higher interest rates have resulted in a lower volume of mortgage loans sold in the secondary market during 2022 compared to the prior year. Other noninterest income decreased $2.1 million for the three months ended June 30, 2022 and $2.6 million for the six months ended June 30, 2022 primarily due to the decline in the fair value of the assets in a nonqualified benefit plan which has a corresponding offset in salaries and benefits resulting in no impact to net income.

Noninterest expense increased $2.6 million to $48.4 million for the three months ended June 30, 2022 and increased $4.3 million to $95.8 million for the six months ended June 30, 2022 compared to the same periods in 2021. Professional services and legal increased by $0.7 million for the three months ended June 30, 2022 and $1.2 million for the six months ended June 30, 2022 due to increased consulting engagements compared to the same periods in 2021. Furniture, equipment and software increased $0.5 million for the three months ended June 30, 2022 and increased $0.7 million for the six month ended June 30, 2022 due to new software implementation costs. Salaries and employee benefits increased $0.3 million for the three months ended June 30, 2022 and increased $0.7 million for the six months ended June 30, 2022 due to base rate and incentive increases partially offset by lower pension expense and a decline in the fair value of the liability in a nonqualified benefit plan.

The provision for income taxes increased $0.3 million to $7.3 million for the three months ended June 30, 2022 and increased $0.1 million to $14.3 million for the six months ended June 30, 2022 compared to $7.0 million and $14.2 million for the same periods in 2021. Our effective tax rate was 20.3 percent and 19.7 percent for the three months and six months ended June 30, 2022 compared to 19.7 percent and 19.1 percent for the three and six months ended June 30, 2021. The increases in our effective tax rates for the three and six month periods ended June 30, 2022 were primarily due to a $0.5 million decrease in low income housing tax credits compared to the same periods in 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. Management also uses return on average tangible shareholders' equity, or ROTE to evaluate and measure performance. These metrics are non-GAAP financial measures. Management believes these performance metrics 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, 2022 Compared to Three and Six Months Ended June 30, 2021 - Net Interest Income" section of this MD&A.

RESULTS OF OPERATIONS

Three and Six Months Ended June 30, 2022 Compared to

Three and Six Months Ended June 30, 2021

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. We believe this to be the preferred industry measurement of net interest income that provides a relevant comparison between taxable and non-taxable sources of interest income.

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

(3) Nonaccruing loans are included in the daily average loan amounts outstanding.

Net interest income on an FTE basis (non-GAAP) increased $6.8 million and $3.7 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. The net interest margin, or NIM, on an FTE basis (non-GAAP) increased 40 and 4 basis points for the three and six months ended June 30, 2022 compared to the same periods in 2021. The increases in net interest income and NIM on an FTE basis (non-GAAP) were primarily due to higher interest rates during 2022.

Interest income on an FTE basis (non-GAAP) increased $5.9 million and $1.1 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. The increases in interest income on an FTE basis (non-GAAP) were primarily due to higher interest rates partially offset by lower Paycheck Protection Program, or PPP, income. Average PPP loans decreased $431.4 million and $413.0 million compared to the three and six months ended June 30, 2021. Average loan balances, excluding PPP loans, increased $298.9 million and $222.6 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. The yield on average loans increased 31 basis points and 6 basis points for the three and

six months ended June 30, 2022 compared to the same periods in 2021 due to increased interest rates. Average securities increased $197.2 million and $208.6 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. Securities increased due to interest-bearing deposits with banks being redeployed to higher yielding assets. Average interest-bearing deposits with banks decreased $257.1 million and increased $96.5 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. Overall, the FTE rate on interest-earning assets (non-GAAP) increased 36 basis points and decreased 2 basis points for the three and six months ended June 30, 2022 compared to the same period in 2021.

Interest expense decreased $0.9 million and $2.6 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. The decreases in interest expense were primarily due to lower average rates paid on interest-bearing deposits compared to the same periods in 2021. Average interest-bearing deposits decreased $341.7 million and $163.2 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. The decreases were concentrated in higher-balance, rate sensitive accounts. Additionally, we discontinued a money market product during the first quarter of 2022 that was indexed to the Federal Funds rate which caused declines in money market balances. The average rate paid on interest-bearing deposits decreased 6 and 9 basis points for the three and six months ended June 30, 2022 compared to the same periods in 2021 primarily due to decreased balances in rate sensitive accounts and the maturities of higher costing certificates of deposit. Average demand deposits increased $137.4 million and $254.2 million for the three and six months ended June 30, 2022 compared to the same periods in 2021. We experienced demand deposit growth throughout 2021 due to customer PPP loans and stimulus payments along with customers' liquidity preferences. Average total borrowings decreased $28.5 million and $23.9 million for the three and six months ended June 30, 2022 compared to the same periods in 2021 due to the payoff of a subordinated debt and lower customer repo balances. Overall, the cost of interest-bearing liabilities decreased 5 and 9 basis points for the three and six months ended June 30, 2022 compared to the same periods in 2021.

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 portfolio at the balance sheet date. The provision for credit losses increased $0.6 million and decreased $3.0 million to $3.2 million and $2.7 million for the three and six months ended June 30, 2022 compared to $2.6 million and $5.7 million for the same periods in 2021. The provision for credit losses included $2.0 million and $2.2 million for the reserve for unfunded commitments for the three and six months ended June 30, 2022 compared to $0.6 million and $0.4 million for the same periods in 2021.

The increase in the provision for credit losses of $0.6 million for the three months ended June 30, 2022 compared to the same period in 2021 was primarily due to an increase of $1.4 million in our provision for unfunded commitments related to higher construction commitments and expected loss rates in our construction portfolio. The decrease in the provision for credit losses of $3.0 million for the six months ended June 30, 2022 compared to the same period in 2021 was due primarily to two large C&I loan recoveries totaling $6.6 million which were received during the six months ended June 30, 2022, and reductions in our quantitative reserve due primarily to significant improvement in our hotel portfolio.

Noninterest income decreased $2.8 million to $12.6 million for the three months ended June 30, 2022 and decreased $4.9 million to $27.9 million for the six months ended June 30, 2022 compared to the same periods in 2021. Mortgage banking decreased $1.3 million for the three months ended June 30, 2022 and decreased $4.6 million for the six months ended June 30, 2022. Higher interest rates have resulted in a lower volume of mortgage loans sold in the secondary market during 2022 compared to the prior year. Other noninterest income decreased $2.1 million for the three months ended June 30, 2022 and $2.6 million for the six months ended June 30, 2022 primarily due to the decline in the fair value of the assets in a nonqualified benefit plan which has a corresponding offset in salaries and benefits resulting in no impact to net income. Service charges on deposit accounts and debit and credit card fees increased for the three and six months ended June 30, 2022 due to an improving economic environment which drove higher customer activity.

related to retirees electing lump-sum distributions causing settlement accounting in the same period in 2021. Other noninterest expenses increased $0.2 million and $0.7 million for the three and six months ended June 30, 2022 due to increased travel and employee expenses and increased expenses in amortization related to our qualified affordable housing projects.

Provision for Income Taxes

The provision for income taxes increased $0.3 million to $7.3 million for the three months ended June 30, 2022 and increased $0.1 million to $14.3 million for the six months ended June 30, 2022 compared to $7.0 million and $14.2 million for the same periods in 2021. Our effective tax rate was 20.3 percent and 19.7 percent for the three months and six months ended June 30, 2022 compared to 19.7 percent and 19.1 percent for the three and six months ended June 30, 2021. The increases in our effective tax rates for the three and six month periods ended June 30, 2022 were primarily due to a $0.5 million decrease in low income housing tax credits compared to the same periods in 2021.

Financial Condition as of June 30, 2022

Total assets decreased $384.7 million to $9.1 billion at June 30, 2022 compared to $9.5 billion at December 31, 2021. Cash and due from banks decreased $577.5 million to $344.7 million at June 30, 2022 compared to $922.2 million at December 31, 2021 primarily due to a decrease in deposits of $384.3 million. Total portfolio loans increased $40.9 million to remain relatively stable at $7.0 billion at June 30, 2022 compared to December 31, 2021. The commercial loan portfolio decreased $109.5 million compared to December 31, 2021. C&I loans decreased $33.9 million which mainly related to a decline in PPP loans of $76.6 million since December 31, 2021. The consumer loan portfolio increased $150.4 million with increases in consumer real estate of $138.4 million and other consumer of $12.0 million. Excluding the PPP loans, portfolio loans increased $117.5 million compared to December 31, 2021.

Securities increased $157.8 million to $1.1 billion at June 30, 2022 from $910.8 million at December 31, 2021. The increase in securities is primarily due to interest-bearing deposits with banks being redeployed to higher yielding assets. The bond portfolio had a net unrealized loss of $61.9 million at June 30, 2022 compared to a net unrealized gain of $9.4 million at December 31, 2021 due to higher interest rates.

Our deposits decreased $384.3 million to $7.6 billion at June 30, 2022 compared to $8.0 billion at December 31, 2021. Noninterest-bearing demand deposits were stable at $2.7 billion at June 30, 2022 compared to December 31, 2021. Interest-bearing demand deposits decreased $98.7 million and money market decreased $182.1 million which was concentrated in higher balance, rate sensitive accounts. Certificates of deposits decreased $107.0 million due to maturities compared to December 31, 2021.

Total borrowings decreased $45.6 million to $115.7 million at June 30, 2022 compared to $161.3 million at December 31, 2021. The decrease in borrowings is primarily related to a decline in securities sold under repurchase agreements of $45.2 million compared to December 31, 2021.We no longer offer repurchase agreements as a product for our customers and the remaining balance is in process of being transferred to other deposit products.

Total shareholders’ equity decreased by $28.1 million to remain relatively stable at $1.2 billion at June 30, 2022 compared to December 31, 2021. The decrease was primarily due to other comprehensive losses of $60.1 million, dividends of $23.2 million and common stock repurchases of $4.2 million offset by net income of $58.0 million. The $60.1 million in other comprehensive losses was primarily due to net unrealized losses of $61.9 million on our available-for-sale bond portfolio due to interest rate increases from December 31, 2021 to June 30, 2022.

We invest in various securities in order to maintain a source of liquidity, to satisfy various pledging requirements, to increase net interest income and as a tool of ALCO to reposition the balance sheet for interest rate risk purposes. Securities are subject to market risks that could negatively affect the level of liquidity available to us. Security purchases are subject to an investment policy approved annually by our Board of Directors and administered through ALCO and our treasury function. Securities increased $157.8 million to $1.1 billion at June 30, 2022 from $910.8 million at December 31, 2021. The increase in securities was primarily due to investing interest-bearing deposits with banks into higher yielding assets.

At June 30, 2022, our bond portfolio was in a net unrealized loss position of $61.9 million compared to a net unrealized gain position of $9.4 million at December 31, 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 increased $40.9 million to remain relatively stable at $7.0 billion at June 30, 2022 compared to December 31, 2021. Portfolio loans excluding PPP loans increased $117.5 million compared to December 31, 2021. As of June 30, 2022, 74 percent of our total loans are variable rate loans and 26 percent are fixed rate loans.

Commercial loans, including CRE, C&I and commercial construction, comprised 75.2 percent of total portfolio loans at June 30, 2022 and 77.2 percent at December 31, 2021. The commercial loan portfolio decreased $109.5 million at June 30, 2022 compared to December 31, 2021. C&I loans decreased $33.9 million at June 30, 2022 which mainly related to a PPP loan decline of $76.6 million since December 31, 2021.

We had $11.7 million of PPP loans included in C&I at June 30, 2022 compared to $88.3 million at December 31, 2021. The decrease in PPP loans was due to loan forgiveness. 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. These loans carry a fixed rate of 1 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 24.8 percent of our total portfolio loans at June 30, 2022 and 22.8 percent at December 31, 2021. The consumer loan portfolio increased $150.4 million at June 30, 2022 with increases in consumer real estate of $138.4 million and other consumer of $12.0 million compared to December 31, 2021. Portfolio consumer real estate loans increased in 2022 due to a shift from mortgage loans sold to loans held in the portfolio due to increased jumbo loans and the pricing of loans in the secondary market.

Allowance for Credit Losses

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

The following table presents activity in the ACL for the periods presented:

Allowance for credit losses as a percentage of total portfolio loans 1.39 % 1.41 %
Allowance for credit losses as a percentage of total portfolio loans - excluding PPP loans 1.40 % 1.43 %
Allowance for credit losses to nonperforming loans 309 % 149 %

(1) Year-to-date net charge-offs annualized

The ACL was $98.1 million, or 1.39 percent of total portfolio loans, at June 30, 2022 compared to $98.6 million, or 1.41 percent of total portfolio loans, at December 31, 2021. The quantitative reserve decreased $5.4 million primarily due to significant improvement in our hotel portfolio. Specific reserves on loans individually assessed decreased $1.8 million due to the resolution of a C&I relationship through a note sale which resulted in a $5.5 million charge-off during the three months ended June 30, 2022. The qualitative reserve increased $6.7 million primarily due to additional segment allocations made in our healthcare portfolio and an increase in our economic forecast related to concerns with rising inflation and macroeconomic conditions.

Net loan charge-offs were $1.0 million, or 0.01 percent of average loans, for the six months ended June 30, 2022. The most significant charge-off was the above mentioned C&I relationship for $5.5 million. Offsetting loan charge-offs were $6.6 million of loan recoveries related to two C&I relationships during the six months ended June 30, 2022.

Substandard loans decreased $36.9 million to $198.3 million at June 30, 2022 compared to $235.2 million at December 31, 2021. The decrease in substandard loans was due to $42.7 million of loan upgrades in our hotel portfolio and $30.5 million of

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

loan payoffs. The decrease in substandard loans was partially offset by the addition of a $28.5 million C&I relationship, which was downgraded to substandard due to financial deterioration that led to cash flow shortfalls during the second quarter of 2022. Special mention loans decreased $9.3 million to $183.0 million at June 30, 2022 compared to $192.3 million at December 31, 2021. The decrease in special mention loans was primarily due to loan upgrades in our hotel portfolio.

Troubled debt restructurings, or TDRs, decreased $18.4 million to $13.3 million at June 30, 2022 compared to $31.7 million at December 31, 2021. The decrease in TDRs was primarily due to the payoff of two C&I relationships totaling $14.1 million and a CRE relationship totaling $5.7 million. Total TDRs of $13.3 million included $9.3 million, or 70.0 percent, that were accruing and $4.0 million, or 30.0 percent, that were nonaccruing at June 30, 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 (Loss). The allowance for unfunded loan commitments increased $2.2 million to $7.4 million at June 30, 2022 compared to $5.2 million at December 31, 2021. This change was primarily related to higher construction commitments and expected loss rates in our construction portfolio. The allowance for unfunded commitments is included in other liabilities in the Consolidated Balance Sheets.

Nonperforming assets consist of nonaccrual loans, nonaccrual TDRs and OREO. The following table summarizes nonperforming assets for the dates presented:

All values are in US Dollars.

Our policy is to place loans in all categories in nonaccrual status when collection of interest or principal is doubtful, or generally when interest or principal payments are 90 days or more past the contractual due date. Nonperforming loans decreased $34.5 million, or 52.0 percent, to $31.8 million at June 30, 2022 compared to $66.3 million at December 31, 2021. The significant decrease in nonperforming loans primarily related to the payoff of two C&I relationships totaling $14.1 million and a CRE relationship totaling $5.7 million. Additionally, four hotel loans were returned to performing status totaling $6.7 million during the six months ended June 30, 2022. The decrease in OREO related to the sale of a property for $6.3 million during the first quarter of 2022.

All values are in US Dollars.

Deposits are our primary source of funds. Our deposit base increased substantially through the Pandemic related to PPP and stimulus programs but we have experienced a decrease in deposits during 2022. Total deposits decreased $384.3 million, or 4.8%, compared to December 31, 2021. Our noninterest-bearing demand deposits remain stable from December 31, 2021. Interest-bearing demand deposits decreased $98.7 million and money market decreased $182.1 million which was concentrated in higher balance, rate sensitive accounts. Additionally, we discontinued a money market product during the first quarter of 2022 that was indexed to the Federal Funds rate which resulted in declines in money markets. Certificates of deposits decreased $107.0 million due to maturities compared to December 31, 2021.

Liquidity and Capital Resources

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

Our primary funding and liquidity source is a stable customer deposit base. We believe S&T has the ability to retain existing and attract new deposits, mitigating any funding dependency on other more volatile sources. Refer to the "Financial Condition as of June 30, 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.

We have contractual obligations representing required future payments on certificates of deposit, securities sold under repurchase agreements, junior subordinated debt securities, operating and capital leases and purchase obligations. See the Liquidity and Capital Resources portion of our Management’s Discussion and Analysis of Financial Condition and Results of Operations in our 2021 Form 10-K for more information on these future cash outflows.

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

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, 2022, S&T Bank had $991.2 million in highly liquid assets which consisted of $263.0 million in interest-bearing deposits with banks, $726.9 million in unpledged securities and $1.3 million in loans held for sale. This resulted in a highly liquid assets to total assets ratio of 10.9 percent at June 30, 2022. Highly liquid assets have declined by $309.8 million when comparing June 30, 2022 to December 31, 2021. The majority of the decrease in liquid assets is attributed to decreases in cash balances which are primarily a result of decreased deposits. At June 30, 2022, we had remaining borrowing availability of $2.8 billion with the FHLB of Pittsburgh. For more information regarding our outstanding borrowings refer to the "Financial Condition as of June 30, 2022 - Borrowings" section of this MD&A for more details.

We continue to maintain a strong capital position with our leverage ratio at 10.25 percent at June 30, 2022 compared to 9.74 percent at December 31, 2021, both in excess of the regulatory guideline of 5.00 percent. We continue to be well-capitalized with a risk-based Common Equity Tier 1 ratio of 12.34 percent at June 30, 2022 compared to 12.03 percent at December 31, 2021, both in excess of the regulatory guideline of 6.50 percent to be well-capitalized.

The following table summarizes capital amounts and ratios for S&T and S&T Bank for the dates presented:

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, 2022, we had not issued any securities pursuant to this shelf registration statement.

S&T is monitoring and will continue to monitor the impact of the pandemic and has taken and will continue to take steps to mitigate the potential risks and impact on our liquidity and capital resources. Due to the economic uncertainty, we are taking a prudent approach to capital management.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

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

Rate shock analyses results are compared to a base case to provide an estimate of the impact that market rate changes may have on 12 and 24 months of pretax net interest income. The base case and rate shock analyses are performed on a static balance sheet. A static balance sheet is a no growth balance sheet in which all maturing and/or repricing cash flows are reinvested in the same product at the existing product spread. Rate shock analyses assume an immediate parallel shift in market interest rates and also include management assumptions regarding the impact of interest rate changes on non-maturity deposit products (noninterest-bearing demand, interest-bearing demand, money market and savings) and changes in the prepayment behavior of loans and securities with optionality. S&T policy guidelines limit the change in pretax net interest income over 12 and 24 month horizons using rate shocks in increments of +/- 100 basis points. Policy guidelines define the percentage change in pretax net interest income by graduated risk tolerance levels of minimal, moderate and high. 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 less improvement in the percentage change in pretax net interest income in the rates up scenarios and a larger decline in the rates down scenario when comparing June 30, 2022 to December 31, 2021. We benefit less in the increasing rate scenarios because we have less excess cash. We have a larger decline in the decreasing rate scenario because the higher rate environment has increased our asset yields while our liability costs have remain unchanged to date. A decline in interest rates would result in less interest income with limited interest expense reduction. 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, 2022 to December 31, 2021. The EVE changes are due to the impact of interest rates on the value of nonmaturity 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.

There have been no material changes to the risk factors that we have previously disclosed in Part I, Item 1A – “Risk Factors” in our 2021 Form 10-K for the year ended December 31, 2021, as filed with the SEC on February 28, 2022 other than the risks described below.

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 21, 2022, our Board of Directors authorized an extension of the $50 million share repurchase plan, which was set to expire March 31, 2022. This authorization extended the expiration date of the repurchase plan through March 31, 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 $33.3 million of capacity remaining at June 30, 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.

S&T BANCORP, INC. 2021 INCENTIVE PLAN RESTRICTED STOCK UNIT AWARD AGREEMENT 1. Award of Restricted Stock Units. Pursuant to the S&T Bancorp, Inc. 2021 Incentive Plan (the “Plan”), S&T Bancorp, Inc. (the “Company”) hereby grants a Restricted Stock Unit Award to the Grantee (the “Award”). Upon acceptance of this Award, the Grantee shall receive the Share Amount, as set forth below, from the Company’s Compensation Committee of the Board of Directors (the “Committee”), subject to the restrictions and conditions set forth in the Plan and this Restricted Stock Unit Award Agreement (this “Agreement”). 2. Acceptance of Award. The Grantee shall have no rights with respect to this Award unless he or she shall have accepted this Award. 3. Restrictions and Conditions. Restricted Stock Units granted herein are subject to restrictions as set forth in the Plan and this Agreement. 4. Vesting of Restricted Stock Units. Except as otherwise provided in this Agreement, Restricted Stock Units covered by the Award shall become vested upon occurrence of the applicable Vesting Date shown below. 5. Death, Disability, or Retirement. Notwithstanding anything herein to the contrary, if Grantee should terminate employment from the Company due to death or disability (as those terms are defined in the Company’s qualified retirement plan) prior to the Vesting Date, the Award shall vest on a pro-rata basis as of the date of such event. The prior sentence shall also apply if the Grantee terminates employment from the Company due to Retirement (Age 62 with ten years of service) but only with respect to Time Restricted Stock Unit Award. If the Grantee terminates employment from the Company due to Retirement, any service requirement associated with the unvested Performance Restricted Stock Unit Award shall be deemed satisfied and the Performance Restricted Stock Unit Award shall continue to be eligible to vest based on the satisfaction of the applicable Performance Standards. 6. Forfeiture. Except as otherwise provided in this Agreement, termination for cause or upon breach of a restrictive covenant shall result in forfeiture of the Award (vested and unvested). However, if the Grantee should terminate employment from the Company prior to full vesting of any portion of the Award for any reason other than death or disability, or retirement, participation will cease as of the effective date of termination, and the Award, to the extent not previously vested, shall be forfeited. The Committee’s determination of the reason for termination of the Grantee’s employment shall be conclusive and binding on the Grantee and his or her representatives or legatees. For purposes of this section, “cause” shall mean, as determined by the Committee: (i) failure to substantially perform duties as reasonably assigned hereunder (other than by reason of

disability), after reasonable written demand for substantial performance has been delivered by the Company specifically identifying the manner in which the Company believes Grantee has not performed Grantee’s duties, and Grantee has been given a reasonable opportunity (not to exceed fifteen (15) days) to cure any deficiencies in performance; (ii) willful misconduct that demonstrably results in material injury to the Company or their affiliates; (iii) fraud, dishonesty or willful breach of fiduciary duty that is injurious to the Company or their affiliates; (iv) conviction or plea of guilty or nolo contendere to any felony or crime involving moral turpitude, fraud or dishonesty; (v) willful violation of any law, rule or regulation (other than traffic violations, misdemeanors or similar offenses) or cease-and-desist order, court order, judgment or supervisory agreement that demonstrably results in material injury to the Company or their affiliates; or (vi) a material breach by Grantee of (A) Grantee’s obligations under this Agreement or (B) any material written policy of the Company or their affiliates and, if the breach is curable, Grantee shall not have cured such material breach after reasonable written demand for cure has been delivered by the Company specifically identifying the material breach, and Grantee has been given a reasonable opportunity (not to exceed fifteen (15) days) to cure any such material breach (to the extent curable). 7. Settlement of Restricted Stock Units. (a) The Restricted Stock Units shall be settled by the Company delivering to the Grantee (or after the Grantee’s death, the Grantee’s beneficiary), on the applicable scheduled settlement date a number of Shares equal to the number of Restricted Stock Units vested as of such date, together with any related Dividend Equivalents (as defined below). (b) For purposes of this Agreement, the “scheduled settlement date” shall be as soon as administratively feasible following vesting; provided that, the scheduled settlement date shall be no later than March 15 of the calendar year following the year in which the underlying Restricted Stock Unit vests. (c) The delivery of any certificate representing Shares may be postponed by the Company for such period as may be required for it to comply with any applicable foreign, federal, state, or provincial securities law, or any national securities exchange listing requirements, and the Company is not obligated to issue or deliver any Shares if, in the opinion of counsel for the Company, such issuance or delivery constitutes a violation by the Grantee or the Company of any provisions of any applicable foreign, federal, state, or provincial securities law or of any regulations of any governmental authority or any national securities exchange. For the avoidance of doubt, the grant of the Restricted Stock Units and the issuance of any Shares pursuant to this Agreement shall be subject to compliance with all applicable requirements of federal or state law with respect to such securities. 8. Dividend Equivalents. If the Company pays cash or stock dividends on the Common Stock, an amount equal to (a) the dollar amount of such cash dividend or (ii) the Fair Market Value of such stock dividend will be credited to a dividend equivalent account on behalf of the Grantee with respect to the Time Restricted Stock Unit Award. Credits on account of cash dividends will 2

be held uninvested and will not accrue interest. Credits on account of stock dividends will be deemed to be reinvested in shares of Common Stock. All dividend equivalents will be paid in cash if and when the corresponding Restricted Stock Units are settled. No dividend equivalents will be accrued or paid on Performance Restricted Stock Units. 9. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Agreement shall be subject to and governed by all the terms and conditions of the Plan, including the powers of the Committee set forth in the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein. The terms of the Plan shall not be considered an enlargement of any benefits under this Agreement. In addition, the Award is subject to any rules and regulations promulgated by the Committee. However, any Award subject to this Agreement may not in any way be restricted or limited by any Plan amendment or termination or by change of Committee rules and regulations approved after the Grant Date without the Grantee’s written consent. 10. Transferability. This Agreement (and the underlying Restricted Stock Units) is personal to the Grantee, is non-assignable, and is not transferable in any manner, by operation of law or otherwise, other than (i) by will or the laws of descent and distribution or (ii) pursuant to an order issued under state domestic relations laws. 11. Shareholder Rights. Neither the Grantee nor any person claiming through the Grantee shall have any rights as a stockholder with respect to any Restricted Stock Units, unless and until the Grantee has become the holder of record of the Shares, all conditions with respect to the issuance of the Shares have been satisfied in full, and the Shares shall have been issued and delivered to the Grantee. 12. Tax Withholding. Except as otherwise provided in this Agreement, the Grantee shall, not later than the date as of which the receipt of this Award becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Committee for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event. Except as otherwise provided in this Agreement, the Company shall have the authority to cause the required minimum tax withholding obligation to be satisfied, in whole or in part, by withholding from shares of Common Stock to be issued or released by the transfer agent a number of Shares with an aggregate Fair Market Value that would satisfy the withholding amount due. 13. Section 409A. The Restricted Stock Units are intended to be exempt from, or compliant with, Section 409A of the Code and shall be interpreted accordingly. 14. Fractional Shares. Fractional Shares will not be issued. 15. Adjustments. If at any time while the Award is outstanding, the number of outstanding Shares is changed by reason of reorganization, recapitalization, stock split, or any other event that affects the number and kind of Restricted Stock Units, the number and kind of Restricted Stock Units will be adjusted in accordance with the provisions of the Plan. 3

  1. Governing Law. This Agreement shall be governed by the laws of the Commonwealth of Pennsylvania, other than its choice of law provisions. 17. Conflicts. In the event of any conflict between the provisions of the Plan and the provisions of this Agreement, the provisions of the Plan shall govern. 18. Grantee Bound by Plan. By accepting this Agreement, the Grantee hereby acknowledges receipt of a copy of the prospectus and Plan document and agrees to be bound by all the terms and provisions thereof. 19. No Obligation to Continue Service. Neither the Company nor any affiliate is obligated by or as a result of the Plan or this Agreement to continue the Grantee in service and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any affiliate to terminate the service of the Grantee at any time. 20. Notices. Notices hereunder shall be mailed or delivered to the Company at its principal place of business and shall be mailed or delivered to the Grantee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in writing. 21. Force and Effect. The various provisions of this Agreement are severable in their entirety. Any determination of invalidity or unenforceability of any one provision shall have no effect on the continuing force and effect of the remaining provisions. 22. Successors. This Agreement shall be binding upon and inure to the benefit of the successors, assigns, and heirs of the respective parties. 23. Entire Agreement. This Agreement contains the entire understanding of the parties and shall not be modified or amended except in writing and duly signed by the parties. No waiver by either party of any default under this Agreement shall be deemed a waiver of any later default. 4

The Committee’s determination of the reason for termination of the Grantee’s service shall be conclusive and binding on the Grantee and his or her representatives or legatees. For purposes of this section, “cause” shall mean, as determined by the Committee: (i) failure to substantially perform duties as reasonably assigned hereunder (other than by reason of disability), after reasonable written demand for substantial performance has been delivered by the Company specifically identifying the manner in which the Company believes Grantee has not performed Grantee’s duties, and Grantee has been given a reasonable opportunity (not to exceed fifteen (15) days) to cure any deficiencies in performance; (ii) willful misconduct that demonstrably results in

material injury to the Company or their affiliates; (iii) fraud, dishonesty or willful breach of fiduciary duty that is injurious to the Company or their affiliates; (iv) conviction or plea of guilty or nolo contendere to any felony or crime involving moral turpitude, fraud or dishonesty; (v) willful violation of any law, rule or regulation (other than traffic violations, misdemeanors or similar offenses) or cease-and-desist order, court order, judgment or supervisory agreement that demonstrably results in material injury to the Company or their affiliates; or (vi) a material breach by Grantee of (A) Grantee’s obligations under this Agreement or (B) any material written policy of the Company or their affiliates and, if the breach is curable, Grantee shall not have cured such material breach after reasonable written demand for cure has been delivered by the Company specifically identifying the material breach, and Grantee has been given a reasonable opportunity (not to exceed fifteen (15) days) to cure any such material breach (to the extent curable). 7. Settlement of Restricted Stock Units. (a) The Restricted Stock Units shall be settled by the Company delivering to the Grantee (or after the Grantee’s death, the Grantee’s beneficiary), on the applicable scheduled settlement date a number of Shares equal to the number of Restricted Stock Units vested as of such date, together with any related Dividend Equivalents (as defined below).

For the avoidance of doubt, the grant of the Restricted Stock Units and the issuance of any Shares pursuant to this Agreement shall be subject to compliance with all applicable requirements of federal or state law with respect to such securities. 8.

If the Company pays cash or stock dividends on the Common Stock, an amount equal to (a) the dollar amount of such cash dividend or (ii) the Fair Market Value of such stock dividend will be credited to a dividend equivalent account on behalf of the Grantee with respect to the Time Restricted Stock Unit Award. Credits on account of cash dividends will be held uninvested and will not accrue interest. Credits on account of stock dividends will be deemed to be reinvested in shares of Common Stock. All dividend equivalents will be paid in cash if and when the corresponding Restricted Stock Units are settled. 2

  1. Incorporation of Plan. Notwithstanding anything herein to the contrary, this Agreement shall be subject to and governed by all the terms and conditions of the Plan, including the powers of the Committee set forth in the Plan. Capitalized terms in this Agreement shall have the meaning specified in the Plan, unless a different meaning is specified herein. The terms of the Plan shall not be considered an enlargement of any benefits under this Agreement. In addition, the Award is subject to any rules and regulations promulgated by the Committee. However, any Award subject to this Agreement may not in any way be restricted or limited by any Plan amendment or termination or by change of Committee rules and regulations approved after the Grant Date without the Grantee’s written consent. 10. Transferability. This Agreement (and the underlying Restricted Stock Units) is personal to the Grantee, is non-assignable, and is not transferable in any manner, by operation of law or otherwise, other than (i) by will or the laws of descent and distribution or (ii) pursuant to an order issued under state domestic relations laws. 11. Shareholder Rights. Neither the Grantee nor any person claiming through the Grantee shall have any rights as a stockholder with respect to any Restricted Stock Units, unless and until the Grantee has become the holder of record of the Shares, all conditions with respect to the issuance of the Shares have been satisfied in full, and the Shares shall have been issued and delivered to the Grantee. 12. Tax Withholding. Except as otherwise provided in this Agreement, the Grantee shall, not later than the date as of which the receipt of this Award becomes a taxable event for Federal income tax purposes, pay to the Company or make arrangements satisfactory to the Committee for payment of any Federal, state, and local taxes required by law to be withheld on account of such taxable event. Except as otherwise provided in this Agreement, the Company shall have the authority to cause the required minimum tax withholding obligation to be satisfied, in whole or in part, by withholding from shares of Common Stock to be issued or released by the transfer agent a number of Shares with an aggregate Fair Market Value that would satisfy the withholding amount due. 13. Section 409A. The Restricted Stock Units are intended to be exempt from, or compliant with, Section 409A of the Code and shall be interpreted accordingly. 14. Fractional Shares. Fractional Shares will not be issued. 15. Adjustments. If at any time while the Award is outstanding, the number of outstanding Shares is changed by reason of reorganization, recapitalization, stock split, or any other event that affects the number and kind of Restricted Stock Units, the number and kind of Restricted Stock Units will be adjusted in accordance with the provisions of the Plan. 16. Governing Law. This Agreement shall be governed by the laws of the Commonwealth of Pennsylvania, other than its choice of law provisions. 3

  1. Conflicts. In the event of any conflict between the provisions of the Plan and the provisions of this Agreement, the provisions of the Plan shall govern. 18. Grantee Bound by Plan. By accepting this Agreement, the Grantee hereby acknowledges receipt of a copy of the prospectus and Plan document and agrees to be bound by all the terms and provisions thereof. 19. No Obligation to Continue Service. Neither the Company nor any affiliate is obligated by or as a result of the Plan or this Agreement to continue the Grantee in service and neither the Plan nor this Agreement shall interfere in any way with the right of the Company or any affiliate to terminate the service of the Grantee at any time. 20. Notices. Notices hereunder shall be mailed or delivered to the Company at its principal place of business and shall be mailed or delivered to the Grantee at the address on file with the Company or, in either case, at such other address as one party may subsequently furnish to the other party in writing. 21. Force and Effect. The various provisions of this Agreement are severable in their entirety. Any determination of invalidity or unenforceability of any one provision shall have no effect on the continuing force and effect of the remaining provisions. 22. Successors. This Agreement shall be binding upon and inure to the benefit of the successors, assigns, and heirs of the respective parties. 23. Entire Agreement. This Agreement contains the entire understanding of the parties and shall not be modified or amended except in writing and duly signed by the parties. No waiver by either party of any default under this Agreement shall be deemed a waiver of any later default. 4
