NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. BASIS OF PRESENTATION

Principals of Consolidation

The interim Consolidated Financial Statements include the accounts of S&T Bancorp, Inc. and subsidiaries (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 (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 our annual report on Form 10-K for the year ended December 31, 2010, filed with the SEC on March 16, 2011. In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly S&Ts financial position and 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.

Use of Estimates

The preparation of financial statements in conformity with U.S. generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates.

Recently Adopted Accounting Standards Updates

Disclosures about Credit Quality and the Allowance for Credit Losses

In July 2010, the Financial Accounting Standards Board (FASB) issued an accounting standards update (ASU) that significantly increases disclosures about the credit quality of financing receivables and the allowance for credit losses, and requires additional information, such as aging information and credit quality indicators disaggregated by portfolio segment and class. The disaggregated information is based on how a company develops its allowance for credit losses and how it manages its credit exposure. Required disclosures as of the end of a reporting period are effective for periods ending on or after December 15, 2010, while required disclosures about activity that occurs during a reporting period are effective for periods beginning on or after December 15, 2010. Required disclosures specifically related to troubled debt restructurings were deferred in an ASU issued in January 2011. The effect of this update is included in the notes to the consolidated financial statements. The adoption of this ASU did not have a material impact on S&Ts consolidated financial statements.

Fair Value Measurements

In January 2010, the FASB issued an ASU requiring new disclosures on transfers into and out of Level 1 and 2 fair value measurements of the fair value hierarchy and requiring separate disclosures about purchases, sales, issuances, and settlements relating to Level 3 measurements. It also clarifies existing fair value disclosures relating to the level of disaggregation and inputs and valuation techniques used to measure fair value. It was effective for the first reporting period (including interim periods) beginning after December 15, 2009, except for the requirement to provide the Level 3 activity of purchases, sales, issuances, and settlements on a gross basis, which was effective for fiscal years beginning after December 15, 2010. The additional Level 3 disclosures that are now required have been included in the notes to the consolidated financial statements. The adoption of this ASU did not have a material impact on S&Ts consolidated financial statements.

Goodwill Impairment

In December 2010, the FASB issued an ASU that modifies step 1 of the goodwill impairment test for reporting units with zero or negative carrying amounts. For those reporting units, an entity is required to perform Step 2 of the goodwill impairment test if it is more likely than not that a goodwill impairment exists. In determining whether it is more likely than not that a goodwill impairment exists, an entity should consider whether there are any adverse qualitative factors indicating that an impairment may exist. The qualitative factors are consistent with the existing guidance and examples, which require that goodwill of a reporting unit be tested for impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying amount. For public entities, the amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2010. The adoption of this ASU did not have a material impact on S&Ts consolidated financial position.

Recently Issued Accounting Standards Updates not yet Adopted

Troubled Debt Restructurings

In April 2011, the FASB issued an ASU clarifying when a loan modification or restructuring is considered a troubled debt restructuring. The guidance is effective for the first interim period beginning on or after June 15, 2011, and should be applied retrospectively to the beginning of the annual period of adoption. For purposes of measuring impairment on newly-considered impaired receivables an entity should apply the guidance prospectively in the first interim period beginning on or after June 15, 2011. The disclosures relating to troubled debt restructurings will be required in the first interim period beginning on or after June 15, 2011. The adoption of this ASU is not expected to have a material impact on S&Ts consolidated financial statements.

Reclassification

Certain prior period amounts have been reclassified to conform to the current years presentation. The reclassifications had no significant effect on S&Ts financial condition or results of operations.

NOTE 2. CAPITAL PURCHASE PROGRAM

On January 16, 2009, S&T completed a $108.7 million capital raise as a participant in the U.S. Treasury Capital Purchase Program (CPP). In conjunction with S&Ts participation in the CPP, S&T issued to the U.S. Treasury 108,676 shares of S&Ts Series A Preferred Stock. The Series A Preferred Stock pays cumulative dividends at a rate of five percent per year for the first five years and thereafter at a rate of nine percent per year. As part of its purchase of the Series A Preferred Stock, the U.S. Treasury received a Warrant to purchase 517,012 shares of S&Ts common stock at an initial per share exercise price of $31.53. The Warrant provides for the adjustment of the exercise price and the number of shares of S&Ts common stock issuable upon exercise pursuant to customary anti-dilution provisions, such as upon stock splits or distributions of securities or other assets to holders of S&Ts common stock and upon certain issuances of S&Ts common stock at or below a specified price relative to the initial exercise price.

Under changes made to the CPP by the American Recovery and Reinvestment Act of 2009 (ARRA), S&T can redeem the Series A Preferred Stock, plus any accrued and unpaid dividends, subject to approval by banking regulatory agencies, at any time. If S&T only redeems part of the CPP investment, then it must pay a minimum of 25 percent of the issuance price, or $27.2 million. The consent of the U.S. Treasury will be required for S&T to increase its common stock dividend (above the dividend amount prior to S&Ts participation in the CPP) or repurchase its common stock or other equity or capital securities, other than in connection with benefit plans consistent with past practice and certain other circumstances through January 16, 2012. The consent of the U.S. Treasury will not be required if S&T has redeemed the Series A Preferred Stock or the U.S. Treasury has transferred the Series A Preferred Stock to a third party. In addition, the Series A Preferred Stock issuance includes certain restrictions on executive compensation that could limit the tax deductibility of compensation S&T pays to executive management.

The Warrant expires ten years from the issuance date. In addition, the U.S. Treasury has agreed not to exercise voting power with respect to any shares of common stock issued upon exercise of the Warrant.

NOTE 3. FAIR VALUE MEASUREMENTS

S&T uses fair value measurements to record fair value adjustments to certain financial assets and liabilities and to determine fair value disclosures. Securities available-for-sale, trading assets and derivatives are recorded at their estimated fair value on a recurring basis. Additionally, from time to time, S&T may be required to record at fair value other assets on a nonrecurring basis, such as loans held for sale, impaired loans, other real estate owned (OREO), mortgage servicing rights (MSR) 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, S&T uses 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 obtained from sources independent of S&T. Unobservable inputs reflect S&Ts estimate 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:

Table of Contents

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS continued

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 instruments level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. S&Ts policy is to recognize transfers between any of the fair value hierarchy levels at the end of the reporting period in which the transfer occurred.

The following is a description of the valuation methodologies that S&T uses for financial instruments recorded at estimated fair value on either a recurring or nonrecurring basis:

Recurring Basis

Securities Available-for-Sale

Securities available-for-sale include both debt and equity securities.

S&T obtains estimated fair values for debt securities from a third-party pricing service, which utilizes several sources for valuing fixed-income securities. The market evaluation sources for debt securities include observable inputs rather than significant unobservable inputs and are classified as Level 2.

S&Ts collateralized mortgage obligations and mortgage-backed securities of U.S. government corporations and agencies are valued based on market data. The service provider utilizes evaluated pricing models that vary by asset class and include available trade, bid and other market information. Generally, the methodologies include broker quotes, proprietary models, vast descriptive terms and conditions databases, as well as extensive quality control programs. All mortgage-backed securities are residential.

S&Ts obligations of states and political subdivisions portfolio is valued using proprietary valuation matrices from the service provider. The market evaluation model includes a separate curve structure for the bank-qualified versus general market municipals. For the bank-qualified municipals, the source is the service providers own trading desk. Securities are further broken down according to insurer, credit support, state of issuance and rating to incorporate additional spreads and municipal curves.

Marketable equity securities that have an active, quotable market are classified in Level 1. Marketable equity securities that are quotable, but are thinly traded or inactive, are classified as Level 2 and securities that are not readily traded and do not have a quotable market are classified as Level 3. All marketable equity securities are in the financial services industry.

Trading Assets

When available, S&T uses quoted market prices to determine the fair value of trading assets. S&Ts only trading asset is a Rabbi Trust for deferred compensation plans, which is invested in two readily quoted mutual funds. The assets within the Rabbi Trust are classified as Level 1.

Derivative Financial Instruments

S&T calculates the fair value for derivatives using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. Each valuation considers the contractual terms of the derivative, including the period to maturity and uses observable market based inputs, such as interest rate curves and implied volatilities. As such, estimates of fair value are classified as Level 2.

S&T incorporates credit valuation adjustments into the valuation models to appropriately reflect both its own nonperformance risk and the respective counterpartys nonperformance risk in calculating fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, S&T has considered the impact of netting and any applicable credit enhancements and collateral postings.

Nonrecurring Basis

Loans Held for Sale

Loans held for sale consist of 1-4 family residential loans originated for sale in the secondary market and carried at the lower of cost or fair value. Periodically, it may be necessary to record fair value adjustments under lower of cost or fair value. S&T determines fair value based on reference to quoted market prices for similar assets and liabilities. As a result, such estimates of fair value are classified as Level 2.

Impaired Loans

A loan is considered impaired when it is probable that S&T will be unable to collect all interest and principal payments due according to the original contractual terms of the loan agreement. S&T individually evaluates all substandard and doubtful commercial loans greater than $0.5 million for impairment and any other commercial loans greater than $0.5 million identified by management that show signs of impairment. S&T establishes a specific reserve based on the following three impairment methods: 1) the present value of expected future cash flows discounted at the loans effective interest rate, 2) the loans observable market price or 3) the fair value of the collateral less estimated selling costs when the loan is collateral dependent. Collateral values are generally based upon appraisals from approved, independent state certified appraisers. Fair value is determined as the recorded investment balance less any specific reserve.

Appraisals may be discounted based on managements historical knowledge, changes in market conditions from the time of valuation or managements knowledge of the borrower and the borrowers business. Since not all valuation inputs are observable, S&T classifies these nonrecurring fair value determinations as Level 2 or Level 3 based on the lowest level of input that is significant to the fair value measurement.

OREO and Other Repossessed Assets

OREO and other repossessed assets are comprised of commercial construction and commercial and residential real estate properties obtained in partial or total satisfaction of loan obligations. OREO acquired in settlement of indebtedness is recorded at estimated fair value less cost to sell. Subsequent to foreclosure, these assets are carried at the lower of carrying value or current estimated fair value less cost to sell. Accordingly, it may be necessary to record nonrecurring fair value adjustments. Fair value, when recorded, is generally based upon appraisals by approved, independent state certified appraisers. OREO and other repossessed assets are classified as Level 2.

Mortgage Servicing Rights

The fair value of MSR is determined by calculating the present value of estimated future net servicing cash flows, considering expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected rate of mortgage loan prepayments is the most significant factor driving the value of MSR. As the valuation model includes significant unobservable inputs, MSR are classified as Level 3. If the carrying value of MSR exceeds fair value, they are considered impaired. As a result, they are carried at fair value and classified within Level 3 of the fair value hierarchy.

Other Assets

In accordance with GAAP, S&T measures certain other assets at fair value on a nonrecurring basis. Fair value is based on the application of lower of cost or fair value accounting or write downs of individual assets. Valuation methodologies used to measure fair value are consistent with overall principles of fair value accounting and consistent with those described above.

Financial Instruments

In addition to financial instruments recorded at fair value in S&Ts financial statements, fair value accounting guidance requires disclosure of the fair value of all of an entitys assets and liabilities that are considered financial instruments. The majority of S&Ts assets and liabilities are considered financial instruments as defined in the guidance. Many of these instruments lack an available trading market as characterized by a willing buyer and willing seller engaged in an exchange transaction. Also, it is S&Ts general practice and intent to hold its financial instruments to maturity and to not engage in trading or sales activities. For fair value disclosure purposes, S&T substantially utilized the fair value measurement criteria as required and explained above. In cases where quoted fair values are not available, S&T uses present value methods to determine the fair value of its financial instruments.

Cash and Cash Equivalents and Other Short-Term Assets

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

Loans

The fair values of variable rate performing loans is based on carrying values adjusted for credit risk. The fair values for other performing loans is estimated using discounted cash flow analyses, utilizing interest rates currently being offered for loans with similar terms, adjusted for credit risk. The fair values of nonperforming loans is based on their carrying values less any specific reserve. The carrying amount of accrued interest approximates fair value.

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS continued

Bank Owned Life Insurance

Fair value approximates net cash surrender value.

Deposits

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

Short-Term Borrowings

The carrying amounts of federal funds purchased, securities sold under repurchase agreements and other short-term borrowings approximate their fair values.

Long-Term Borrowings

The fair values disclosed for fixed-rate long-term borrowings are determined by discounting their contractual cash flows using current interest rates for long-term borrowings of similar remaining maturities. The carrying amounts of variable rate long-term borrowings approximate their fair values.

Junior Subordinated Debt Securities

For the variable rate junior subordinated debt securities that reprice quarterly, fair values are based on carrying values. For the $25.0 million junior subordinated debt issued with a fixed rate period of five years which then converts to a variable rate, fair valued is based on discounted cash flows at current interest rates during the fixed rate period.

Loan Commitments and Standby Letters of Credit

Off-balance sheet financial instruments consist of commitments to extend credit and letters of credit. Except for interest rate lock commitments, 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.

Other

Estimates of fair value have not been made for items that are not defined as financial instruments, including such items as S&Ts core deposit intangibles and the value of its trust operation.

NOTE 4. DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES

Interest Rate Swaps

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

Pursuant to S&Ts agreements with various financial institutions, S&T may receive collateral or may be required to post collateral based upon mark-to-market positions. Beyond unsecured threshold levels, collateral in the form of cash or securities may be made available to counterparties of swap transactions. Based upon S&Ts current positions and related future collateral requirements relating to them, S&T believes any affect on its cash flow or liquidity position to be immaterial. Derivatives contain an element of credit risk, the possibility that S&T will incur a loss because a counterparty, which may be a financial institution or a customer, fails to meet its contractual obligations. All derivative contracts with financial institutions may be executed only with counterparties approved by S&Ts Asset and Liability Committee (ALCO) and derivatives with customers may only be executed with customers within credit exposure limits approved by S&Ts Board of Directors Loan Committee. Interest rate swaps are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the fair value of the derivatives are recorded in current earnings and included in other noninterest income in the Consolidated Statements of Income.

Interest Rate Lock Commitments and Forward Sales Contracts

In the normal course of business, S&T sells originated mortgage loans into the secondary mortgage loan market. S&T offers interest rate lock commitments to potential borrowers. The commitments are generally for 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. In addition, S&T can encounter pricing risk if interest rates increase significantly before the loan can be closed and sold. S&T 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 S&T and in turn a forward sale contract may be executed between S&T and the investor. Both the rate lock commitment and the corresponding forward sale contract for each customer are considered derivatives, but are not accounted for using hedge accounting. As such, changes in the fair value of the derivatives during the commitment period are recorded in current earnings and included in mortgage banking in the Consolidated Statements of Income.

S&T does not believe any individual unrealized loss as of March 31, 2011 represents an other-than-temporary impairment (OTTI). S&T performs a review of its securities for OTTI on a quarterly basis to identify securities that may indicate an OTTI. Generally, S&T records an impairment charge when an equity security within the marketable equity securities portfolio has been in a loss position for 12 consecutive months, unless facts and circumstances suggest the need for an OTTI prior to that time. S&Ts policy for recording an OTTI within the debt securities portfolio is based upon a number of factors, including but not limited to, the length of time and the extent to which fair value has been less than cost, the financial condition of the underlying issuer, the ability of the issuer to meet contractual obligations, the likelihood of a security recovering from any decline in fair value and whether management intends to sell the security or if it is more likely than not that management will be required to sell the security prior to the it recovering.

As of March 31, 2011, the unrealized losses on 30 debt securities were primarily attributable to changes in interest rates. The unrealized losses on 7 marketable equity securities as of March 31, 2011 were attributable to temporary declines in fair value. S&T does not intend to sell and it is not likely that S&T will be required to sell any of the securities, referenced in the table above, in an unrealized loss position before recovery of its amortized cost.

NOTE 6. RESTRICTED INVESTMENT IN BANK STOCK

S&T is a member of the Federal Home Loan Bank (FHLB) of Pittsburgh. The FHLB requires member banks to purchase and hold FHLB stock based on their Member Asset Value, as defined and calculated by the FHLB on an annual basis, and their level of activity with the FHLB, including, among other things, advances and letters of credit. Stock in the FHLB is non-marketable and is redeemable at the discretion of the FHLB. Members do not purchase stock in the FHLB for the same reasons that traditional equity investors acquire stock in an investor-owned enterprise. Rather, members purchase stock to obtain access to the low-cost products and services offered by the FHLB. Unlike equity securities of traditional for-profit enterprises, FHLB stock does not provide its holders with an opportunity for capital appreciation because, by regulation, it can only be purchased, redeemed and transferred at par value.

At March 31, 2011 and December 31, 2010, S&Ts FHLB stock totaled $21.2 million and $22.4 million, respectively. This investment is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value.

In December 2008 the FHLB suspended the payment of dividends and the repurchase of excess capital stock until further notice. On October 28, 2010 the FHLB announced that it would partially lift its suspension on the repurchase of excess capital stock and would review future excess capital stock repurchases on a quarterly basis. Management reviewed the FHLBs Form 10-K for the period ended December 31, 2010 filed with the SEC on March 18, 2011 to support their conclusion around OTTI of FHLB stock.

S&T believes its holdings in the stock are ultimately recoverable at par value as of March 31, 2011 and, therefore, determined that the FHLB stock was not OTTI. In addition, S&T has sufficient liquidity and does not require redemption of its FHLB stock in the foreseeable future. On October 29, 2010, S&T received $1.2 million from the FHLB to redeem 11,771 shares of capital stock, $1.1 million for the redemption of 11,183 shares on February 24, 2011 and an additional $1.1 million for the redemption of 10,624 shares on April 29, 2011.

S&T attempts to limit its exposure to credit risk by diversifying its loan portfolio and actively managing concentrations. When concentrations exist in certain segments, S&T mitigates this risk by monitoring relevant economic indicators and internal risk rating trends, and through stress testing of the loans in those segments. Since S&T is primarily a lender to businesses in western Pennsylvania, there is a concentration in commercial loans as well as a geographic loan concentration in Pennsylvania. Commercial loans represent 74 percent of total portfolio loans at both March 31, 2011 and December 31, 2010. Within the commercial portfolio, the commercial real estate (CRE) and commercial construction portfolios combined comprise 71 percent of commercial loans and 53 percent of total loans at both March 31, 2011 and December 31, 2010. Further segmentation of the CRE and commercial construction portfolios by industry and collateral type reveal no concentration in excess of 9 percent of total loans.

The vast majority of both commercial and consumer loans are made to businesses and individuals in S&Ts western Pennsylvania market, resulting in a geographic concentration. The conditions of the local and regional economies are monitored closely through publicly available data as well as information supplied by our customers. Only the CRE and commercial construction portfolios combined have any significant out of state exposure, with 21 percent of the combined portfolio or 11 percent of total loans at both March 31, 2011 and December 31, 2010 being out of state. Management believes underwriting guidelines and ongoing review by loan administration mitigate the concentration risk present in the loan portfolio.

Restructured loans are loans that S&T, for economic or legal reasons related to a borrowers financial difficulties, grants a concession to the borrower that it would not otherwise consider. A concession is considered to have been granted if any of the following occur: a reduction of contractual interest rates below the market interest rate for new debt with similar characteristics, acceptance of other assets or an equity interest in the debtor in partial satisfaction of the debt, a reduction or forgiveness of principal, a reduction or forgiveness of accrued interest, a reduction or deferral of principal, or an extension of the maturity date at a stated interest rate lower than the current market rate for the new debt with similar risk.

NOTE 8. ALLOWANCE FOR LOAN LOSSES

S&T maintains an allowance for loan losses (ALL) at a level determined to be adequate to absorb estimated probable credit losses inherent in the loan portfolio as of the balance sheet date. S&T develops and documents a systematic ALL methodology based on the following portfolio segments: 1) CRE, 2) Commercial and Industrial (C&I), 3) Commercial Construction, 4) Consumer Real Estate and 5) Other Consumer. The following discusses the key risks associated with 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, strip malls and apartments. Individual projects as well as global cash flows 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 as well as 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 do not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt.

Commercial Construction Loans made to finance the construction or building of 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 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.

Consumer Real Estate Loans secured by 1st and 2nd lien home equity loans, home equity lines of credit and 1-4 family residences, 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 portfolio since low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.

Other Consumer Loans made to individuals that may be secured by assets other than 1-4 family residences as well as unsecured loans. This segment includes auto loans, unsecured lines of credit and credit cards. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.

Management further assesses risk within each portfolio segment using the key inherent risk differentiators. For the commercial loan segments, the most important indicator of risk is the internally assigned risk rating, including pass, special mention and substandard. Impaired loans are considered in the ALL model separately and are individually evaluated for impairment. S&Ts internal risk rating system is consistent with definitions found in current regulatory guidelines. A simplified data migration technique is used to calculate the historic average losses over the defined loss emergence period.

Loans in the consumer segments are not individually risk rated; therefore, the most important indicators of risk are the existence of collateral, the type of collateral, and for consumer real estate loans, whether the bank has a 1st or 2nd lien position. A simplified data migration technique is used to calculate the historic average losses over the defined loss emergence period.

Management monitors various credit quality indicators for both the commercial and consumer loan portfolios, including delinquency, nonperforming status and changes in risk ratings on a monthly basis.

The following tables present the age analysis of past due loans segregated by class of loans for the periods stated:

Management continually monitors the commercial loan portfolio through its internal risk rating system. Loan risk ratings are assigned based upon the creditworthiness of the borrower. Loan risk ratings are reviewed on an ongoing basis according to internal policies. Loans within the pass rating generally have a lower risk of loss than loans risk rated as special mention, and substandard, which generally have an increasing risk of loss.

S&Ts 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 managements close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects or in the institutions credit position at some future date. Economic and market conditions, beyond the customers control, may in the future necessitate this classification.

Substandard A substandard loan is not adequately protected by the net worth and/or paying capacity of the obligor 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 the bank will sustain some loss if the deficiencies are not corrected.

NOTE 9. MORTGAGE SERVICING RIGHTS

The value of servicing loans is recognized as part of the interest rate lock derivative value when commitments to fund a loan to be sold are made. Upon sale of the loan, the value of the MSR, is recognized as a separate asset, which represents the then current estimated fair value of future net cash flows expected to be realized for performing the servicing activities. The estimated fair value of MSR is determined by calculating the present value of estimated future net servicing cash flows, considering expected prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected rates of prepayments are the most significant factor driving the value of MSR. Increases in prepayments reduce estimated future net servicing cash flows because the life of the underlying loan is reduced. In determining the estimated fair value of MSR, mortgage interest rates, which are used to determine prepayment rates and discount rates, are held constant over the estimated life of the portfolio. MSR are reported in other assets in the Consolidated Balance Sheets and are amortized into mortgage banking in the Consolidated Statements of Income in proportion to, and over the period of, the estimated future net servicing income of the underlying mortgage loans.

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

MSR are also reviewed for OTTI. OTTI exists when the recoverability of a recorded valuation allowance is determined to be remote, taking into consideration historical and projected interest rates and loan pay-off activity. When this occurs, the unrecoverable portion of the valuation allowance is applied as a direct write-down to the carrying value of the MSR. Unlike a valuation allowance, a direct write-down permanently reduces the carrying value of the MSR and the valuation allowance, precluding subsequent recoveries.

For the three months ended March 31, 2011 and 2010, 1-4 family mortgage loans that were sold to Fannie Mae amounted to $26.4 million and $22.2 million, respectively. At March 31, 2011 and 2010, S&Ts servicing portfolio totaled $331.5 million and $270.9 million, respectively.

NOTE 10. BORROWINGS

Short-term borrowings are for original terms under one year and may be comprised of retail repurchase agreements (REPOs), wholesale REPOs, federal funds purchased and FHLB advances. S&T defines repurchase agreements with its local retail customers as retail REPOs; short-term wholesale REPOs are those transacted with other banks and brokerage firms. Securities pledged as collateral under these REPO financing arrangements cannot be sold or repledged by the secured party and are therefore accounted for as a secured borrowing. The estimated fair value of collateral provided to a third party is continually monitored and additional collateral is obtained or requested to be returned as appropriate. Federal funds purchased are unsecured overnight borrowings with other financial institutions. FHLB advances are for various terms secured by a blanket lien on residential mortgages, other real estate secured loans and FHLB stock with the FHLB of Pittsburgh.

At March 31, 2011 and December 31, 2010, the only short-term borrowings that S&T had outstanding were comprised of REPOs totaling $38.3 million and $40.7 million, respectively.

Long-term debt instruments are for original terms greater than one year and may be comprised of wholesale REPOs, FHLB advances and junior subordinated debt securities. Long-term REPOs and FHLB advances have the same collateral requirements as their short-term equivalents.

The following is a summary of long-term debt for the periods presented:

(in thousands)	March 31, 2011	December 31, 2010
Long-term borrowings	$ 28,974	$ 29,365
Junior subordinated debt securities	90,619	90,619
Total	$ 119,593	$ 119,984

S&T had total long-term debt outstanding of $50.6 million at a fixed rate and $68.7 million at a variable rate at March 31, 2011. Included in long-term borrowings is a capital lease of $0.3 million.

S&T had total borrowings at March 31, 2011 and December 31, 2010 at the FHLB of Pittsburgh of $28.7 million and $29.1 million, respectively. There were no short-term borrowings at the end of the current period. At March 31, 2011, S&T had a maximum borrowing capacity of $1.3 billion with the FHLB of Pittsburgh.

NOTE 11. EMPLOYEE BENEFITS

S&T Bank maintains a defined benefit pension plan (Plan) covering substantially all employees hired prior to January 1, 2008. The benefits are based on years of service and the employees compensation for the highest five consecutive years in the last ten years of employment. Contributions are intended to provide for benefits attributed to employee service to date and for those benefits expected to be earned in the future. S&T made no contributions to its pension plan in 2010 and no contributions are required to be made for 2011 at this time. The expected long-term rate of return on plan assets is 8.00 percent.

NOTE 12. COMMITMENTS AND CONTINGENCIES

Commitments

S&T, in the normal course of business, offers off-balance sheet credit arrangements to enable its customers to meet their financing objectives. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the financial statements. S&Ts exposure to credit loss, in the event a customer does not satisfy the terms of their agreement, equals the contractual amount of the obligation less the value of any collateral. S&T applies 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. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. S&Ts allowance for lending-related commitments totaled $2.9 million at March 31, 2011 and $2.7 million at December 31, 2010. The allowance for lending-related commitments is included in other liabilities in the Consolidated Balance Sheets.

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 customers.

The following table sets forth the commitments and letters of credit for the periods presented:

(in thousands)	March 31, 2011	December 31, 2010
Commitments to extend credit	$ 860,710	$ 836,042
Standby letters of credit	130,508	135,489
Total	$ 991,218	$ 971,531

Litigation

S&T, in the normal course of business, is subject to various legal and administrative proceedings and claims. While any type of litigation contains a level of uncertainty, S&T believes that the outcome of such proceedings or claims will not have a material adverse effect on its consolidated financial position.

Basic earnings per common share (EPS) is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Potentially dilutive securities are excluded from the basic calculation, but are included in diluted EPS. In computing diluted EPS, average common shares outstanding have been increased by the dilutive common stock equivalents relating to S&Ts outstanding stock options and restricted stock. Excluded from the calculation were anti-dilutive stock options of 746,435 and 1,082,706 shares and anti-dilutive restricted stock of 11,954 and 3,557 shares for the three months ended March 31, 2011 and 2010, respectively. Further 517,012 common stock warrants were anti-dilutive at both March 31, 2011 and 2010.

The following table reconciles the weighted average common shares outstanding used to calculate basic EPS to the weighted average common shares used to calculate diluted EPS:

2011	2010
Weighted average common shares outstanding (basic)	27,936,723	27,724,495
Effect of dilutive stock options and restricted stock	20,279	28,889
Weighted Average Common Shares Outstanding (Diluted)	27,957,002	27,753,384

changes in interest rates, spreads on earning assets and interest-bearing liabilities, the shape of the yield curve and interest rate sensitivity;

a prolonged period of low interest rates;

credit losses;

financial resources in the amounts, at the times and on the terms required to support our future businesses;

legislation affecting the financial services industry as a whole, and/or S&T, including the effects of the Dodd-Frank Wall Street Reform and Consumer Protection Act;

regulatory supervision and oversight, including required capital levels, and public policy changes, including environmental regulations;

increasing price and product/service competition by competitors, including new entrants;

reliance on large customers;

the outcome of pending and future litigation and governmental proceedings;

managing our internal growth and acquisitions;

general economic or business conditions, either nationally or regionally in western Pennsylvania, may be less favorable than expected, resulting in among other things, a reduced demand for credit and other services;

a decline in market capitalization to common book value, which could warrant further analysis of the carrying value of goodwill and could result in an adjustment to its carrying value resulting in a charge to net income; and

a continuation of recent turbulence in significant portions of the global financial and real estate markets 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.

These are representative of the Future Factors that could affect the outcome of the forward-looking statements. In addition, such statements could be affected by general industry and market conditions and growth rates, general economic conditions, including interest rate and currency exchange rate fluctuations and other Future Factors.

Critical Accounting Policies and Estimates

S&Ts critical accounting policies involving the significant judgments and assumptions used in the preparation of the Consolidated Financial Statements as of March 31, 2011 have remained unchanged from the disclosures presented in S&Ts Annual Report on Form 10-K for the year ended December 31, 2010 under the section Managements Discussion and Analysis of Financial Condition and Results of Operations.

Overview

S&T is a bank holding company headquartered in Indiana, Pennsylvania with assets of $4.1 billion at March 31, 2011. S&T provides a full range of financial services through 51 branch offices located in Allegheny, Armstrong, Blair, Butler, Clarion, Clearfield, Indiana, Jefferson and Westmoreland counties of Pennsylvania. S&T provides full service retail and commercial banking products as well as cash management services, insurance, estate planning and administration, employee benefit plan investment management and administration, corporate services, and other fiduciary services.

S&T earns revenue primarily from interest on loans, securities investments and fees charged for financial services provided to its customers. Offsetting these revenues are the cost of deposits and other funding sources, provision for loan losses and other operating costs such as: salaries and employee benefits, occupancy, data processing expenses and tax expense. S&Ts strategic plan to deliver profitable growth to its shareholders includes: increasing loans and core deposits with sufficient interest rate spreads, controlling loan delinquency and loan losses, controlling operating expenses, expanding the business through organic growth and acquisitions, introducing new products and services and expanding the products and services provided to its existing customers. S&Ts common stock trades on the Nasdaq Global Select Market under the symbol STBA.

Net income available to common shareholders for the first quarter of 2011 was $4.7 million resulting in diluted earnings per common share of $0.17 compared to net income of $9.8 million and $0.35 diluted earnings per share in the first quarter of 2010. The decrease in net income was primarily driven by an increase in the provision for loan losses. During the first quarter of 2011, a provision of $10.6 million was recorded compared to $4.4 million in the first quarter of 2010. The provision increased primarily due to an increase in the general reserve as a result of an increase in substandard loans, all of which were downgraded in response to an updated evaluation of each credit based on receipt of recently available financial information. Net interest margin declined to 3.92 percent for the first quarter of 2011 compared to 4.00 percent in the same period in the prior year.

Asset quality will continue to be a primary driver of our results for the remainder of fiscal 2011. We remain diligent and focused on monitoring our nonperforming assets. S&T continually strives to be well positioned for changes in both the economy and interest rates, regardless of the timing or direction of these changes. Management regularly assesses our balance sheet, capital, liquidity and operation infrastructures in order to be positioned to take advantage of internal or acquisition growth.

Explanation of Use of Non-GAAP Financial Measures

In addition to the results of operations presented in accordance with GAAP, management uses, and this quarterly report contains or references, certain non-GAAP financial measures, such as net interest income on a fully taxable equivalent basis and operating revenue. Management believes these non-GAAP financial measures provide information useful to investors in understanding S&Ts underlying operational performance and its business and performance trends as they facilitate comparisons with the performance of others in the financial services industry. Although management believes that these non-GAAP financial measures enhance investors understanding of S&Ts business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP.

Table of Contents

Item 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS continued

Management believes the presentation of net interest income on a fully taxable equivalent basis ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice. Interest income per the Consolidated Statements of Income is reconciled to net interest income adjusted to a fully taxable equivalent basis in the table below for the three months ended March 31, 2011 and 2010.

Operating revenue is the sum of net interest income and noninterest income less securities gains. In order to understand the significance of net interest income to S&Ts business and operating results, management believes it is appropriate to evaluate the significance of net interest income as a component of operating revenue.

RESULTS OF OPERATIONS

Three Months Ended March 31, 2011 Compared to

Three Months Ended March 31, 2010

Net Income

Net income available to common shareholders was $4.7 million or $0.17 diluted earnings per share for the first quarter of 2011 compared to $9.8 million or $0.35 diluted earnings per share for the same period in 2010. The decrease in net income was principally driven by a $1.0 million decline in net interest income and a $6.2 million increase in the provision for loan losses, partially offset by a $2.1 million decrease in the provision for income taxes, resulting from the decline in pretax income. The common return on average assets was 0.47 percent for the three months ended March 31, 2011, compared to 0.96 percent for the three months ended March 31, 2010. The common return on average common equity was 3.31 percent for the three months ended March 31, 2011 compared to 7.12 percent for the same period in 2010.

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. Maintaining consistent spreads between interest-earning assets and interest-bearing liabilities is significant to S&Ts financial performance because net interest income comprised 76 percent of operating revenue (net interest income plus noninterest income, excluding securities gains) in the first quarters of 2011 and 2010. The level and mix of interest-earning assets and interest-bearing liabilities are continually monitored by S&Ts Asset and Liability Committee (ALCO), in order to mitigate interest rate and liquidity risks of the balance sheet. A variety of ALCO strategies were successfully implemented, within prescribed ALCO risk parameters, to maintain an acceptable net yield on interest-earning assets (net interest margin) given the challenges of the current interest rate environment.

The following table reconciles interest income per the Consolidated Statements of Income to net interest income adjusted to a fully taxable equivalent basis:

(in millions)	Three Months Ended March 31, — 2011	2010
Interest income	$ 42.2	$ 45.3
Taxable equivalent adjustment to interest income	1.0	1.2
Interest Income on a Fully Taxable Equivalent Basis	43.2	46.5

Average Balance Sheet and Net Interest Income Analysis

The following table provides information regarding the average balances and yields earned on interest-earning assets and the average balances and rates paid on interest-bearing liabilities:

TOTAL	$ 4,087.4			$ 4,137.5
Net Yield on Interest-earning Assets (1)			3.92 %			4.00 %
Net Interest Income (1)		$ 35.9			$ 37.1

(1) The yield on interest-earning assets and the net interest margin are presented on a fully taxable equivalent (FTE) and annualized basis. The FTE basis adjusts for the tax benefit of income on certain tax-exempt loans and investments using the federal statutory tax rate of 35 percent for each period presented. S&T believes this measure to be the preferred industry measurement of net interest income and provides relevant comparison between taxable and non-taxable amounts.

When comparing the first quarter of 2011 to the first quarter of 2010 on a fully taxable-equivalent basis, net interest income and net interest margin decreased by $1.2 million and 8 basis points, respectively. The decline in the net interest margin is a result of loan repricing and replacement volume at lower rates and an unfavorable shift in asset mix, offset by a better funding mix between deposits, including noninterest-bearing demand deposits and borrowings.

Average securities increased by $31.9 million and the fully taxable-equivalent yield decreased by 104 basis points. The average securities balance and yield were impacted by securities maturities, lower rates on new securities, and an increase in excess funds held at the Federal Reserve. Average loans decreased by $79.5 million and the fully taxable-equivalent yield decreased by 20 basis points. Overall, the fully taxable-equivalent yield on interest-earning assets decreased 30 basis points to 4.72 percent.

Average interest-bearing deposits decreased by $40.2 million mainly due to a $33.9 million decrease in brokered certificates of deposit. The cost of deposits was 0.97 percent, a decrease of 24 basis points due to lower rates paid on deposits. Average borrowings decreased by $127.4 million and 65 basis points. Overall, the yield on interest-bearing liabilities decreased 24 basis points to 1.10 percent.

Net interest income was positively impacted by a $120.0 million increase in average net free funds. Average net free funds are the excess of noninterest-bearing demand deposits, other noninterest-bearing liabilities and shareholders equity over noninterest-earning assets. The largest driver of the increase in net free funds was noninterest-bearing demand deposits. Noninterest-bearing demand deposits increased as a result of the low interest rate environment, marketing efforts for new demand accounts, corporate cash management services and the unlimited FDIC deposit insurance protection provided by the Dodd-Frank Act.

The following table sets forth for the periods indicated a summary of the changes in interest earned and interest paid resulting from changes in volume and changes in rates:

(1) Tax-exempt income is on a fully taxable equivalent basis using the statutory federal corporate income tax rate of 35 percent for 2011 and 2010.

(2 ) The change in interest due to both volume and rate has been allocated to volume and rate changes in proportion to the relationship of the absolute dollar amounts of the change in each.

Provision for Loan Losses

The provision for loan losses is the amount to be added to the ALL after adjusting for charge-offs and recoveries to bring the allowance to a level considered appropriate to absorb probable losses inherent in the loan portfolio. The provision for loan losses increased $6.2 million to $10.6 million at the end of the first quarter of 2011 compared to $4.4 million at the end of the first quarter of 2010. This increase was primarily driven by an increase in the general reserve resulting from the downgrade of several loans, all of which were downgraded in response to an updated evaluation of each credit based on receipt of recently available financial information.

Charge-offs totaled $2.6 million and $2.2 million in the first quarter of 2011 and 2010, respectively and were partially offset by recoveries of $2.2 million and $1.2 million, respectively. The specific reserve for impaired loans decreased $11.7 million to $8.6 million at March 31, 2011 compared to $20.3 million at March 31, 2010. Through December 31, 2010 the majority of the loans associated with the $20.3 million reserve recorded at March 31, 2010 were charged off leaving a specific reserve of $3.6 million at year end. During the first quarter of 2011, the specific reserve increased $5.0 million primarily due to the addition of two large relationships. The allowance for loans losses was 1.87 percent of total loans at March 31, 2011 compared to 1.85 percent at March 31, 2010.

Table of Contents

Item 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS continued

Noninterest income decreased $0.3 million to $11.0 million in the first quarter of 2011 compared to the first quarter of 2010. Service charges on deposits, primarily overdraft fees, decreased $0.6 million due to a regulatory change (Regulation E), which was implemented on August 15, 2010. Under Regulation E customers with existing accounts are required to opt in for overdraft coverage on certain types of electronic banking activities. Many customers have not opted to continue the coverage resulting in a decrease in customer overdraft fees. The decrease in insurance fees of $0.2 million is primarily driven by a decline in annual bonus commission income, which is based on insurance customers annual loss rates. Prior year annual bonus commissions were unusually high and the current year has returned to more normalized levels. Mortgage banking increased $0.2 million primarily due to an increase in the fair value of mortgage servicing rights resulting from an increase in the volume of loans being serviced and a projected decrease in prepayment speeds given the current low interest rate environment. Debit and credit card fees increased primarily due to S&T switching from multiple debit card service providers to a single provider that contracted with the bank at higher rates. The $0.2 million decrease in other noninterest income is due to a decline in derivative fee income and change in the mark-to-market swap valuation from a gain in the first quarter of the prior year to a loss in the quarter ended March 31, 2011, all of which were partially offset by an increase in ATM interchange fees.

Noninterest Expense

Salaries and employee benefits	$ 13,320	$ 12,565	$ 755

Other noninterest expense	5,780	5,076	704
Total Noninterest Expense	$ 27,449	$ 27,930	$ (481	)

Noninterest expense decreased $0.5 million in the first quarter of 2011 compared to the first quarter of 2010. The decrease was driven primarily by a $1.8 million decrease in legal expense, that was partially offset by a $0.8 million increase in salaries and employee benefits and $0.7 million increase in other noninterest expense. The decrease in legal expense is attributable to the incurrence of legal expenses in the first quarter of 2010 that did not recur in the first quarter of 2011. The increase in salaries and employee benefits reflects a salary increase that impacted the first quarter of 2011 but not the first quarter of 2010 since the increase was not effective until June 2010. Additionally, payroll taxes and certain other benefits increased as a result of the increase in base salaries. These increases were partially offset by a reduction in the level of incentive compensation accrued in the first quarter of 2011 compared to the first quarter of 2010. Other noninterest expense increased primarily due to an increase in the reserve for unfunded loan commitments.

Provision for Income Taxes

The provision for income taxes decreased $2.1 million to $1.5 million for the first quarter of 2011 compared to $3.6 million for the same period in the prior year, primarily due to a decrease in pre-tax income. The year-to-date 2011 effective tax rate decreased to 19.4 percent as compared to 24.1 percent in 2010 due to recognition of nonrecurring tax return adjustments related to previously filed tax returns, an increase in low-income housing credits, partially offset by a lower level of tax-exempt income expected for the current year.

Financial Condition

Total assets decreased slightly in first quarter of 2011 compared to December 31, 2010. Continuing weak loan demand, coupled with higher than expected pay downs resulted in a slight decrease in the net loan portfolio. Consistent with managements strategic initiative to further strengthen overall liquidity, funds generated from loan pay downs and the sale of loans held for sale were reinvested in securities, resulting in an increase in the securities available-for-sale portfolio. There was a small decline in total deposits due to minor decreases in interest-bearing demand deposits, money market accounts and certificates of deposit, which for the most part were offset by an increase in noninterest bearing deposit accounts. Additionally, brokered certificates of deposit experienced a significant decrease in the first quarter of 2011.

S&T invests in various securities in order to provide a source of liquidity, to satisfy various pledging requirements, increase net interest income and as a tool of the 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 S&T. Risks associated with various securities portfolios are managed and monitored by investment policies approved annually by S&Ts Board of Directors and administered by ALCO and the Treasury function of S&T Bank. The net increase in securities of $43.5 million resulted from the redeployment of funds received from loan pay downs in light of current and expected slow loan growth and managements strategic initiative to further strengthen overall liquidity and reduce asset sensitivity.

On a quarterly basis, management evaluates the securities portfolios for OTTI in accordance with the applicable accounting guidance for investments reported at fair value. No impairment charges were recorded in the first quarter of 2011.

The loan portfolio represents the most significant source of interest income for S&T. The risk that borrowers will be unable to pay such obligations is inherent in the loan portfolio. Other conditions such as the overall economic climate can significantly impact a borrowers ability to pay. In order to mitigate such risk, loan underwriting standards for S&T are established by a formal policy and are subject to periodic review and approval by S&Ts Board of Directors.

Loans decreased by $59.6 million between December 31, 2010 and March 31, 2011. There were slight declines in both the consumer and commercial loan portfolios, primarily due to loan prepayments and reduced demand. Given the current economic environment loan growth is expected to remain a challenge throughout the remainder of 2011.

Although commercial loans, including commercial real estate (CRE), commercial and industrial (C&I) and construction, can have a relatively higher risk profile, management believes these risks are mitigated through active portfolio management, underwriting and continuous review. The loan-to-value policy guidelines for CRE loans are generally 65-85 percent.

Residential mortgage lending continues to be a strategic focus through a centralized mortgage origination department, ongoing product redesign, secondary market activities and the utilization of commission compensated originators. The loan-to-value policy guideline is 80 percent for residential first lien mortgages. Higher loan-to-value loans may be approved with the appropriate private mortgage insurance coverage. Second lien positions are assumed with home equity loans, but normally only to the extent that the combined credit exposure for both the first and second liens does not exceed 100 percent of the estimated fair value of the property.

Management believes the downturn in the local residential real estate market and the impact of declining values on the real estate loan portfolio will be mitigated because of S&Ts conservative mortgage lending policies for portfolio loans, which require a maximum term of 20 years for fixed rate mortgages. Balloon mortgages are also offered in the portfolio. The maximum balloon term is 15 years with a maximum amortization term of 30 years. Balloon mortgages with terms of 10 years or less may have a maximum amortization term for up to 40 years. Combo mortgage loans consist of a residential first mortgage and a home equity second mortgage are also available to creditworthy borrowers.

S&T designates specific loan originations, generally longer-term, lower-yielding 1-4 family mortgages, as held for sale and sells them to Fannie Mae. The rationale for these sales is to mitigate interest-rate risk associated with holding lower rate, long-term residential mortgages in the loan portfolio, generate fee revenue from sales and servicing and maintain the primary customer relationship. During the three months ended March 31, 2011 and 2010, S&T sold $26.4 million and $22.2 million, respectively, of 1-4 family mortgages and currently services $331.5 million of secondary market mortgage loans to Fannie Mae at March 31, 2011. S&T intends to continue to sell longer-term loans to Fannie Mae in the future, especially during periods of lower interest rates.

S&T offers a variety of unsecured and secured consumer loans and credit card products.

Allowance for Loan Losses

S&T maintains an ALL at a level determined to be adequate to absorb estimated probable credit losses inherent in the loan portfolio as of the balance sheet date. The methodology used is based on the following portfolio segments: 1) CRE, 2) C&I, 3) Commercial Construction, 4) Consumer Real Estate and 5) Other Consumer.

The following is a discussion of the key risks by portfolio segment that management assesses in preparing the ALL. CRE loans are secured by commercial purpose real estate, including both owner occupied properties and investment properties for various purposes such as hotels, strip malls and apartments. Individual project cash flows, as well as global cash flows, are generally the 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 as well as the business prospects of the lessee, if the project is not owner occupied.

C&I loans are 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 do not have sufficient value in a distressed or liquidation scenario to satisfy the outstanding debt.

Commercial Construction loans are made to finance the construction or building of 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 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.

Consumer Real Estate loans are secured by 1-4 family residences, including purchase money mortgages, 1st and 2nd lien home equity loans and home equity lines of credit. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The state of the local housing market can also have a significant impact on this portfolio, since low demand and/or declining home values can limit the ability of borrowers to sell a property and satisfy the debt.

Other Consumer loans are made to individuals that may be secured by assets other than 1-4 family residences, as well as unsecured loans. This segment includes auto loans, unsecured lines and credit cards. The primary source of repayment for these loans is the income and assets of the borrower. The condition of the local economy, in particular the unemployment rate, is an important indicator of risk for this segment. The value of the collateral, if there is any, is less likely to be a source of repayment due to less certain collateral values.

Item 2. MANAGEMENTS DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS continued

Significant to the ALL is a higher mix of commercial loans. These loans are generally larger in size and many are not seasoned and may be more vulnerable to an economic slowdown. Management relies on its loan review process to ensure the integrity of loan risk ratings and to assess potential weaknesses within specific credits. Current risk factors, trends in risk ratings and historical charge-off experiences are considered in the determination of the ALL.

Consumer unsecured loans and secured loans that are not real estate secured are evaluated for charge-off after the loan becomes 90 days past due. Unsecured loans are fully charged-off and secured loans are charged-off to the estimated fair value of the collateral less the cost to sell. If the collateral is repossessed and remains unsold for 120 days, the carrying value will be completely charged-off. Consumer loans secured by real estate are evaluated for charge-off after the loan balance becomes 90 days past due and are charged down to the estimated fair value of the collateral less cost to sell.

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

The status of a bankruptcy proceeding

The value of collateral and probability of successful liquidation

The status of adverse proceedings or litigation that may result in collection

The following tables summarize the changes in the ALL for the three months ended March 31:

The ALL at March 31, 2011 was $61.7 million, an increase of $10.3 million from December 31, 2010. The general reserve increased $5.4 million in the first quarter of 2011 due to a significant number of downgrades, primarily in the CRE portfolio, resulting from an updated evaluation of each credit based on receipt of recently available financial information. Specific reserves totaling $8.6 million were included in the ALL at March 31, 2011, an increase of $4.9 million over the amount included in the ALL at December 31, 2010. The increase in specific reserves is primarily attributable to two large relationships totaling $18.8 million for which specific reserves totaling $6.0 million were recorded in the first quarter of 2011, offset by net charge-offs of $0.4 million and a $0.7 million reduction in the specific reserve for a single credit that was resolved.

S&Ts allowance for lending-related commitments is computed using a methodology similar to that used to determine the ALL. Amounts are added to the allowance for lending-related commitments through a charge to current earnings through noninterest expense. The balance in the allowance for lending-related commitments decreased to $2.9 million at March 31, 2011 as compared to $4.0 million at March 31, 2010 due to a significant decrease in the volume of commitments in 2011. The decrease relates to a reduction in commitments due to maturities and utilization of the commitments. The allowance for lending-related commitments is included in other liabilities in the Consolidated Balance Sheets.

Nonperforming assets consist of nonaccrual and restructured loans and OREO. The following table represents nonperforming assets for the periods presented:

(in thousands)	March 31, 2011	December 31, 2010	$ Change

Nonperforming assets include nonaccrual and nonperforming restructured loans and OREO. S&Ts policy is to place loans in all categories on nonaccrual status when collection of interest or principal is doubtful, or generally when interest or principal payments are 90 days or more past due. There are no loans 90 days or more past due and still accruing.

Deposits

(in thousands)	March 31, 2011	December 31, 2010	$ Change
Noninterest-bearing demand	$ 802,748	$ 765,812	$ 36,936
Interest-bearing demand	286,111	295,246	(9,135	)
Money market	240,375	262,683	(22,308	)
Savings	755,311	753,813	1,498
Certificates of deposit	1,221,294	1,239,970	(18,676	)
Total Deposits	$ 3,305,839	$ 3,317,524	$ (11,685	)

Deposits are a primary source of funds for S&T. Management believes that S&Ts deposit base is stable and that it has the ability to attract new deposits, mitigating a funding dependency on other more volatile sources. While total deposits at the end of the first quarter of 2011 were down slightly compared to the first quarter of 2010, S&Ts core deposit base remained stable with the decline being driven primarily by a decline in brokered certificates of deposit. Non-brokered certificates of deposit of $100,000 and over were 12 percent of total deposits at both March 31, 2011 and December 31, 2010, and primarily represent deposit relationships with local customers in our market area. S&T had $40.3 million and $63.0 million of brokered retail certificates of deposit outstanding at March 31, 2011 and December 31, 2010, respectively.

S&T participates in the Certificate of Deposit Account Registry Services (CDARS) program. The reciprocal program allows S&T customers to receive expanded FDIC coverage by placing multiple certificates of deposit at other CDARS member banks. S&T maintains deposits by accepting certificates of deposits from customers of CDARS member banks in the exact amount as S&T customers placed. S&T can also access the CDARS network to accept brokered certificates of deposit that are not part of the reciprocal CDARS program. As of March 31, 2011, the CDARS certificates of deposit were primarily reciprocal totaling $38.4 million. The issuance of brokered retail certificates of deposit and participation in the CDARS program is an ALCO strategy to increase and diversify funding sources.

Borrowings

(in thousands)	March 31, 2011	December 31, 2010	$ Change
Securities sold under repurchase agreements	$ 38,270	$ 40,653	$ (2,383	)
Long-term borrowings	28,974	29,365	(391	)
Junior subordinated debt securities	90,619	90,619	-
Total Borrowings	$ 157,863	$ 160,637	$ (2,774	)

Borrowings are an additional source of funding for S&T. Total borrowings decreased $2.8 million from December 31, 2010 due to the lower balances in REPO. Overall, borrowings decreased as a result of stable deposits and a reduction in earning assets.

Liquidity and Capital Resources

Liquidity refers to the ability to satisfy the financial needs of depositors who want to withdraw funds, or of borrowers needing to access funds to meet their credit needs. The ALCO is responsible for establishing and monitoring liquidity guidelines, policies and procedures.

The principal sources of asset liquidity are cash and due from banks, interest-earning deposits with banks, federal funds sold, unpledged securities available-for-sale, maturing and amortizing loans and securities and earnings. Liability liquidity sources include a stable core deposit base, the ability to renew maturing certificates of deposit, borrowing availability at the FHLB of Pittsburgh (FHLB), fed funds lines with other financial institutions, access to the brokered certificates of deposit market including CDARS, and the ability to raise debt and equity. A stable core and certificates of deposit base provided by S&T customers is an important source of liquidity. A stable deposit base is achieved by maintaining a strong capital position and the protection provided by FDIC insurance. ALCO uses a variety of methods to monitor the liquidity position of S&T. These include a liquidity gap, which measures potential sources and uses of funds over future time periods out to one year. Policy guidelines require S&T to maintain a positive liquidity gap, meaning sources greater than uses, in the 30 day time period. In addition, ratios including net noncore funding dependence, net loans and standby letters of credit to assets, and net loans to deposits are reviewed and monitored. ALCO also performs contingency funding analyses to determine S&Ts ability to meet potential liquidity needs under stress scenarios that cover varying time horizons ranging from immediate to long term. Policy guidelines require coverage ratios of potential sources greater than uses depending on the scenario and time horizon.

Liquidity improved during the first quarter of 2011 as compared to December 31, 2010 due to stable deposit levels and an increase in borrowing capacity at the FHLB. The increase in borrowing capacity at the FHLB is due to reduced borrowings as a result of lower loan and securities balances.

Shareholders equity was $580.1 million and increased $1.4 million at March 31, 2011 compared to $578.7 million at December 31, 2010. S&T had net income available to common shareholders of $4.7 million and dividends paid to common shareholders were $4.2 million for the three months ended March 31, 2011. Also affecting shareholders equity was an increase of $0.5 million due to the issuance of treasury stock, offset by preferred dividends and amortization of $1.6 million and a decrease of $0.2 million in unrealized gains on securities available-for-sale, net of tax, which is included in other comprehensive income.

Management believes that the bank has sufficient cash flow, including cash and cash equivalents, and borrowing capacity to fund all outstanding commitments and letters of credit, while maintaining proper levels of liquidity. Management believes that S&T has the ability to raise additional capital, if necessary.

The following summarizes risk-based capital amounts and ratios for S&T Bancorp, Inc. and S&T Bank:

(in thousands)			March 31, 2011 — Amount	Ratio	December 31, 2010 — Amount	Ratio
S&T Bancorp, Inc.
Tier 1 leverage	4.00%	5.00%	$ 437,556	11.19%	$ 435,823	11.07%
Tier 1 capital to risk-weighted assets	4.00%	6.00%	437,556	13.54%	435,823	13.28%
Total capital to risk-weighted assets	8.00%	10.00%	548,969	16.99%	547,336	16.68%
S&T Bank
Tier 1 leverage	4.00%	5.00%	$ 297,295	7.64%	$ 294,113	7.50%
Tier 1 capital to risk-weighted assets	4.00%	6.00%	297,295	9.25%	294,113	9.02%
Total capital to risk-weighted assets	8.00%	10.00%	407,754	12.69%	405,049	12.42%

(1) For an institution to qualify as adequately capitalized under regulatory guidelines, total risk-based capital, Tier I risk-based capital and Tier I capital to average asset ratios must be at least 8 percent, 8 percent and 4 percent respectively. At March 31, 2011, S&T exceeded those requirements.

(2) For an institution to qualify as well capitalized under regulatory guidelines, total risk-based capital, Tier I risk-based capital and Tier I capital to average asset ratios must be at least 10 percent, 6 percent and 5 percent respectively. At March 31, 2011, S&T exceeded those requirements.

In August 2009, S&T filed a shelf registration statement on Form S-3 under the Securities Act of 1933 as amended, with the SEC for the issuance of up to $300 million of a variety of securities including, debt and capital securities, preferred and common stock and warrants. S&T may use the proceeds from the sale of its securities for general corporate purposes, which could include investments at the holding company level, investing in, or extending credit to, its subsidiaries, possible acquisitions and stock repurchases. As of March 31, 2011, S&T had not issued any securities pursuant to the shelf registration statement.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ALCO monitors and manages interest-rate sensitivity through gap, rate shock analyses, simulations and economic value of equity (EVE) in order to avoid unacceptable earnings fluctuations due to interest rate changes. S&Ts gap model includes certain management assumptions based upon past experience and the expected behavior of customers. The assumptions include principal prepayments for fixed rate loans, collateralized mortgage obligations, and mortgage-backed securities and classifying the demand, savings and money market balances by degree of interest-rate sensitivity.

The gap and cumulative gap represent the net position of assets and liabilities subject to repricing in specific time periods, as measured by a ratio of rate sensitive assets to rate sensitive liabilities. The table below shows the amount and timing of repricing assets and liabilities as of March 31, 2011.

(in thousands)	GAP — 1-6 Months	7-12 Months	13-24 Months	>2 Years
Repricing Assets:
Cash and due from banks and interest- bearing deposits with banks	$ 58,670	$	$	$ 50,185

Total Liabilities and Shareholders Equity	1,382,449	288,190	485,472	1,933,943
GAP	315,225	18,677	27,086	(360,988	)
Cumulative GAP	$ 315,225	$ 333,902	$ 360,988	$

Rate Sensitive Assets / Rate Sensitive Liabilities — Cumulative 6 Months	1.23	1.25
Cumulative 12 Months	1.20	1.18

S&Ts one-year repricing gap at March 31, 2011 indicates an asset sensitive position. This means that more assets than liabilities will reprice during the measured time frames. The implications of an asset sensitive position will differ depending upon the change in market interest rates. For example, with an asset sensitive position in a declining interest rate environment, more assets than liabilities will decrease in rate. This situation could result in a decrease in interest rate spreads, net interest income and operating income. Conversely, with an asset sensitive position in a rising interest rate environment, more assets than liabilities will increase in rate. This situation could result in an increase in interest rate spreads, net interest income and operating income.

In addition to the gap analysis, S&T performs rate shock analyses on a static balance sheet to estimate the effect that specific interest rate changes would have on 12 months of pretax net interest income. Rate shock analyses assume an immediate parallel shift of +/-300 basis points in market interest rates. S&T has modified assumptions in the -300 basis point rate shock analysis due to the very low level of interest rates. Rate shock analyses also incorporate management assumptions regarding the level 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 fixed rate loans and securities with optionality. Inclusion of these assumptions makes rate shock analyses more useful than gap analysis alone. S&Ts policy is to limit the change in pretax net interest income over a one-year horizon to -20 percent given changes in rates using shocks up to +/- 300 basis points.

Table of Contents

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK continued

The table below shows the percent change to pretax net interest income with a rate shock of +/- 300 basis points.

March 31, 2011	11.38 %	(11.30	)%
December 31, 2010	11.67 %	(10.76	)%

The impact to pretax net interest income in the +/-300 basis point rate shocks for March 31, 2011 is consistent with having an asset sensitive balance sheet. When comparing the +/-300 basis point rate shock results in March 31, 2011 to December 31, 2010, the percent change to net interest income is relatively unchanged. When comparing the -300 basis point rate shock results in March 31, 2011 to December 31, 2010, the percent change to net interest income has declined because the balance sheet has become more asset sensitive.

Item 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2011. The term disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (Exchange Act), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SECs rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the companys management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and our management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2011, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

Changes in Internal Control over Financial Reporting

As disclosed in Item 9A of S&Ts Annual Report on Form 10-K for the year ended December 31, 2010, management identified a material weakness in S&Ts internal control over financial reporting as of December 31, 2010 relating to the approval and recording of loan charge-offs. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the companys annual or interim financial statements will not be prevented or detected on a timely basis.

In order to remediate the material weakness, management implemented changes to S&Ts internal control over financial reporting during the quarter ended March 31, 2011. S&T dedicated additional resources to the identification and recording of loan charge-offs. Management also established an internal task force, comprised of members of senior management, including the Chief Financial Officer and the Chief Credit Officer and various members of their respective teams that strengthened our internal process of reviewing and analyzing loan information that may result in a loan charge-off. Based on the recommendations of the task force, management implemented additional processes to strengthen our internal control over financial reporting, including establishing a Managed Asset Committee, comprised of Senior Management in Credit Administration and Finance, to monitor all impaired loans. The task force also implemented and strengthened monitoring procedures by the Credit Administration Department, completed a review of all impaired loans to verify that all charge-offs were recorded and implemented additional charge-off reconcilement procedures. During the quarter ended March 31, 2011, management concluded that the material weakness described above and in S&Ts Annual Report on Form 10-K for the year ended December 31, 2010 has been remediated as of March 31, 2011.

Except for the actions described above to remediate the material weakness described above and in S&Ts Annual Report on Form 10-K for the year ended December 31, 2010, there were no changes in our internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2011 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
