NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. BASIS OF PRESENTATION

Nature of Operations

The accompanying unaudited Consolidated Financial Statements of S&T Bancorp, Inc. and subsidiaries (“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 annual financial statements. In the opinion of management, all adjustments consisting of normal recurring accruals considered necessary for a fair presentation have been included. Operating results for the six-month period ended June 30, 2010 are not necessarily indicative of the results that may be expected for the year ending December 31, 2010.

S&T operates in three business segments, providing a full range of services to individual and corporate customers through Community Banking, Wealth Management and an Insurance Agency. The Consolidated Balance Sheet as of December 31, 2009 has been extracted from the audited financial statements included in S&T’s 2009 annual report on Form 10-K. For further information, refer to the Consolidated Financial Statements and footnotes thereto included in the annual report on Form 10-K for the year ended December 31, 2009, as filed with the Securities and Exchange Commission (“SEC”) on February 26, 2010.

Accounting Policies

The financial statements of S&T have been prepared in accordance with GAAP. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the balance sheets and revenues and expenses for the periods then ended. Actual results could differ from those estimates.

Principals of Consolidation

The Consolidated Financial Statements include the accounts of 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.

Recently Issued and Effective Accounting Pronouncements

Accounting for Transfers of Financial Assets

In June 2009, the Financial Accounting Standards Board (“FASB”) issued an accounting pronouncement regarding accounting for transfers of financial assets, which eliminates the qualifying special-purpose entities (“QSPEs”) concept and associated guidance that had been a significant source of complexity, creates more stringent conditions for reporting a transfer of a portion of financial asset as a sale, clarifies other sale accounting criteria and changes the initial measurement of a transferor’s interest in transferred financial assets. The accounting pronouncement was effective as of January 1, 2010. The adoption of this pronouncement did not have a material impact on S&T’s Consolidated Financial Statements.

Improvements to Financial Reporting by Enterprises Involved with Variable Interest Entities

In June 2009, the FASB issued a pronouncement regarding consolidation accounting, which requires former QSPEs to be evaluated for consolidation and also changes the approach to determining a variable interest entity’s (“VIE”) primary beneficiary. The pronouncement also requires more frequent reassessment as to whether they must consolidate VIEs. The application of this pronouncement to investment companies was deferred indefinitely. This pronouncement was effective as of January 1, 2010. The adoption of this pronouncement did not have a material impact on S&T’s Consolidated Financial Statements.

Fair Value Measurements

In January 2010, the FASB issued an accounting standards update that required more robust disclosures on the fair value of assets and liabilities when an asset or liability is transferred in the fair value hierarchy in or out of Level 1 and 2. This update must be applied for interim and annual periods beginning after January 1, 2010. The adoption of this pronouncement did not have a material impact on S&T’s Consolidated Financial Statements.

Future Application of Accounting Pronouncements

Disclosures About Credit Quality and the Allowance for Credit Losses

Pursuant to the July 2010 FASB accounting standards update, further disclosures will be required about the credit quality of financing receivables and the allowance for credit losses. The disclosures will provide financial statement users with additional information about the nature of credit risks inherent in entities’ financing receivables, how credit risk is analyzed and assessed when determining

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

the allowance for credit losses and the reasons for the change in the allowance for credit losses. This requirement is effective for all periods ending on or after December 15, 2010, although certain disclosures will have a deferred effective date. The accounting standards update requires additional disclosure and will have no impact on the Consolidated Financial Statements.

Fair Value Measurements

Pursuant to the January 2010 FASB accounting standards update, further disclosures will be required for the activity within Level 3 of the fair value hierarchy regarding purchases, sales, issuances and settlements. This requirement is effective for fiscal years beginning after December 15, 2010 and for interim periods within those fiscal years, although early adoption is permitted. The accounting standards update requires additional disclosure and will have no impact on the Consolidated Financial Statements.

Reclassification

Certain amounts in prior years’ financial statements have been reclassed to conform to the current year’s presentation. The reclassifications had no significant effect on S&T’s 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 (the “CPP”). In conjunction with S&T’s participation in the CPP, S&T issued to the U.S. Treasury 108,676 shares of S&T’s 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&T’s 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&T’s 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&T’s common stock and upon certain issuances of S&T’s 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”), subject to approval by banking regulatory agencies, S&T can redeem the Series A Preferred Stock, plus any accrued and unpaid dividends, 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 the 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 proceeds received in conjunction with the issuance of the Series A Preferred Stock and the Warrant were allocated to the preferred stock based on their relative fair values. Estimated fair value was determined using a discounted cash flow model with a 10 percent discount rate. The discount rate was determined by comparison to a group of similarly rated preferred securities in the banking sector. The level yield method is used to amortize the discount on the preferred stock over a period of five years. Management engaged an outside expert to calculate the estimated fair value of the common stock warrants issued by S&T on January 16, 2009. A binomial pricing model was used resulting in an estimated fair value of $4.0 million.

The assumptions used to calculate the estimated fair value of the warrants are summarized below:


Assumption		Value

Contractual term		10 years
Exercise price		$ 31.53
Estimated fair value of company stock		$ 29.14
Expected life		10 years
Risk-free rate over expected life of the warrant		2.36%
Expected volatility		28.4%
Expected dividend yield		3.85%

S&T utilized the average of daily and monthly historical volatility for purposes of this valuation. 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.

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 (“MSRs”) and certain other assets.

Fair value is the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market in an orderly transaction between market participants at the measurement date. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets or liabilities; it is not a forced transaction.

In determining fair value, 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 the asset or liability, which is developed, based on market data obtained from sources independent of S&T. Unobservable inputs reflect S&T’s 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:

Level 1: valuation is based upon unadjusted quoted market prices for identical instruments traded in active markets.

Level 2: valuation is based upon quoted market prices for similar instruments traded in active markets, quoted market prices for identical or similar instruments traded in markets that are not active and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by market data.

Level 3: valuation is derived from other valuation methodologies including discounted cash flow models and similar techniques that use significant assumptions not observable in the market. These unobservable assumptions reflect estimates of assumptions that market participants would use in determining fair value.

A financial instrument’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement.

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&T’s 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.

S&T’s 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 provider’s 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.

Trading Assets

When available, S&T uses quoted market prices to determine the estimated fair value of trading assets. S&T’s only trading asset is a Rabbi Trust for deferred compensation plans, which is invested in two readily quoted mutual funds. The Rabbi Trust is classified as Level 1.

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

Derivative Financial Instruments

S&T calculates the estimated 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 non-performance risk and the respective counterparty’s non-performance risk in the estimated fair value measurements. In adjusting the estimated fair value of its derivative contracts for the effect of non-performance 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 estimated fair value. Periodically, it may be necessary to record fair value adjustments under lower of cost or estimated fair value. S&T determines estimated 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 if management determines that it is probable that S&T will not be able to collect all amounts due according to the contractual terms of the loan agreement of a construction, residential real estate, commercial real estate or commercial and industrial loan greater than $0.5 million. S&T calculates the estimated fair value of impaired loans based upon the present value of expected future cash flows available to pay the loan, or based upon the estimated 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.

Appraisals, whether current or not current, may be discounted based on management’s historical knowledge, changes in market conditions from the time of valuation or management’s knowledge of the borrower and the borrower’s 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 and residential real estate properties obtained in partial or total satisfaction of loan obligations. OREO acquired in settlement of indebtedness is recorded at the lower of carrying amount of the loan or estimated fair value less cost to sell. Subsequent to foreclosure, these assets are carried at the lower of carrying value or 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 from approved, independent state certified appraisers. OREO is classified as level 2.

Mortgage Servicing Rights

The estimated fair value of the MSRs are 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 rates of mortgage loan prepayments are the most significant factors driving the value of MSRs. As the valuation model includes significant unobservable inputs, MSRs are classified as Level 3.

Other Assets

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

Financial Instruments

S&T BANCORP, INC. AND SUBSIDIARIES

instruments. The majority of S&T’s assets and liabilities are considered to be financial instruments as defined in the pronouncement. However, many of such instruments lack an available trading market as characterized by a willing buyer and willing seller engaged in an exchange transaction. Also, it is S&T’s general practice and intent to hold its financial instruments to maturity and to not engage in trading or sales activities. For estimated fair value disclosure purposes, S&T substantially utilized the estimated fair value measurement criteria as required and explained above. In cases where quoted estimated fair values are not available, S&T uses present value methods to determine the estimated 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 approximate those assets estimated fair values.

Loans

For variable rate loans that reprice frequently and with no significant change in credit risk, estimated fair values are based on carrying values. The estimated fair values for other loans are estimated using discounted cash flow analyses, utilizing interest rates currently being offered for loans with similar terms to borrowers as adjusted for net credit losses and the loss of interest income from nonaccrual loans. The carrying amount of accrued interest approximates its estimated fair value.

Bank Owned Life Insurance

The estimated fair value represents the net cash surrender value.

Deposits

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

Long-Term Borrowings

The estimated fair values disclosed for long-term borrowings are estimated by discounting contractual cash flows using current interest rates for long-term borrowings of similar remaining maturities.

Junior Subordinated Debt Securities

For the variable rate junior subordinated debt securities that reprice quarterly, estimated 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&T’s 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 floating) 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&T’s

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

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&T’s 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&T’s 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&T’s Asset and Liability Committee (“ALCO”) and derivatives with customers may only be executed with customers within credit exposure limits approved by S&T’s Board of Directors Loan Committee.

Interest Rate Lock Commitments and Forward Sale 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 estimated fair value of the derivatives during the commitment period are recorded in current earnings and included in other income in the Consolidated Statements of Income (Loss).

S&T’s policy for OTTI declines within the marketable equity securities portfolio requires an impairment charge when the security is in a loss position for 12 consecutive months, unless facts and circumstances would suggest the need for OTTI prior to that time. S&T’s policy for OTTI within the debt securities portfolio is based upon a number of factors, including but not limited to, the length of time and extent to which the estimated 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 the security’s ability to recover any decline in its estimated 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 investment security prior to the security recovery.

The unrealized losses on 15 debt securities at June 30, 2010 were attributable to changes in interest rates. The unrealized losses on marketable equity securities at June 30, 2010 were not significant and were attributable to temporary declines in market 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.

The amount of the net unrealized gains on available-for-sale securities as of June 30, 2010 and December 31, 2009 that have been included in accumulated other comprehensive income were $10.2 million and $7.6 million, respectively. For the three months ended June 30, 2010, approximately $0.1 million of unrealized gains were reclassified out of accumulated other comprehensive income into earnings, totaling $0.3 million for the six month period.

The amortized cost and estimated fair value of debt securities at June 30, 2010, by estimated maturity, is included in the table below. Expected maturities will differ from contractual maturities because the borrowers may have the right to call or prepay the obligation without call or prepayment penalties.


Available-for-Sale	Amortized Cost		Estimated Fair Value
*(dollars in thousands)*

Due in one year or less	$	28,751	$	29,024

Due after ten years		91,758		95,953

Total Debt Securities Available-for-Sale	$	295,424	$	305,207

At June 30, 2010 and December 31, 2009, securities with principal amounts of $207.8 million and $251.4 million, respectively, were pledged to secure repurchase agreements, public funds and trust fund deposits.

NOTE 6. RESTRICTED INVESTMENT IN BANK STOCK

S&T is a member of the Federal Home Loan Bank (“FHLB”) of Pittsburgh. The FHLB requires members to purchase and hold a specified level of FHLB stock based upon their level and availability of borrowings and participation in other programs offered by the FHLB. Stock in the FHLB is non-marketable and is redeemable at the discretion of the FHLB. Both cash and stock dividends are reported as income in taxable investment securities in the Consolidated Statements of Income (Loss). The FHLB has currently suspended the payment of dividends.

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, the stock of the FHLB does not provide its holders with an opportunity for capital appreciation because, by regulation, the FHLB stock can only be purchased, redeemed and transferred at par value.

At June 30, 2010 and December 31, 2009, S&T’s FHLB stock totaled $23.5 million. This investment is carried at cost and evaluated for impairment based on the ultimate recoverability of the par value.

S&T was notified in December 2008 by the FHLB that they have suspended the payment of dividends and the repurchase of excess capital stock until further notice. S&T management reviewed and evaluated the FHLB capital stock for OTTI at June 30, 2010. Management reviewed the FHLB’s Form 10-Q for the period ended March 31, 2010 filed with the SEC on May 10, 2010.

Management considered the following matters when evaluating the FHLB stock for OTTI:

•

Ability of the FHLB to make payments required by law or regulation and the level of such payments in relation to the operating performance of the FHLB. The FHLB is meeting their debt obligations. Although the responsibility to repay debt may be shared among FHLB’s in the event that one FHLB cannot pay, to date, a FHLB has never been required to pay the consolidated obligation of another FHLB.

•

Impact of legislative and regulatory changes on the institution and, accordingly, on the customer base of the FHLB. With the exception of the Housing Act, enacted July 20, 2008, and the Dodd-Frank Wall Street Reform and Consumer Protection Act, or Dodd-Frank Act, enacted on July 21, 2010 (including regulations promulgated pursuant to the Housing Act and Dodd-Frank Act), there are no pending legislative or regulatory changes that would impact the customer base of the FHLB.

•

Liquidity position of the FHLB.

S&T believes its holdings in the FHLB stock are ultimately recoverable at par value as of June 30, 2010 and, therefore, determined that the FHLB stock was not OTTI. In addition, S&T has ample liquidity and does not require redemption of its FHLB stock in the foreseeable future.

The principal balances of loans on nonaccrual status were $77.3 million and $90.8 million at June 30, 2010 and December 31, 2009, respectively. OREO and other repossessed assets, which are included in other assets in the Consolidated Balance Sheets, were $4.7 million at June 30, 2010 and $4.6 million at December 31, 2009. At June 30, 2010, OREO consisted of 24 properties with one residential property comprising $1.5 million or 32 percent of the balance. The $1.5 million residence was recently appraised in February of 2010.

The following table represents S&T’s investment in loans considered to be impaired and related information on those impaired loans for the periods stated:

Allowance for loan losses allocated to loans considered to be impaired	$	8,038	$	17,003
Average recorded balance of impaired loans		83,264		85,606

S&T Bank has granted loans to certain officers and directors of S&T as well as to certain affiliates of the officers and directors in the ordinary course of business. These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated persons and did not involve more than normal risk of collectability. The aggregate dollar amount of these loans was $32.5 million and $34.1 million at June 30, 2010 and December 31, 2009, respectively. As of June 30, 2010, $9.7 million of new loans were funded and repayments of loans totaled $11.3 million.

NOTE 8. MORTGAGE SERVICING RIGHTS

Mortgage servicing assets are recognized as separate assets when commitments to fund a loan to be sold are made. Upon commitment, the MSR is established, 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 the MSRs are 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 rates of mortgage loan prepayments are the most significant factors driving the value of MSRs. Increases in mortgage loan prepayments reduce estimated future net servicing cash flows because the life of the underlying loan is reduced. In determining the estimated fair value of the MSRs, mortgage interest rates, which are used to determine prepayment rates and discount rates, are held constant over the estimated life of the portfolio. MSRs are reported in other assets in the Consolidated Balance Sheets and are amortized into noninterest income in the Consolidated Statements of Income (Loss) in proportion to, and over the period of, the estimated future net servicing income of the underlying mortgage loans.

MSRs are regularly evaluated for impairment based on the estimated fair value of those rights. The MSRs 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.

MSRs 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

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

portion of the valuation allowance is applied as a direct write-down to the carrying value of the MSRs. Unlike a valuation allowance, a direct write-down permanently reduces the carrying value of the MSRs and the valuation allowance, precluding subsequent recoveries.

For the six months ended June 30, 2010 and 2009, the 1-4 family mortgage loans that were sold to Fannie Mae amounted to $37.7 million and $86.0 million, respectively. At June 30, 2010 and 2009, S&T’s servicing portfolio totaled $278.3 million and $224.8 million, respectively.

The following tables indicate MSRs and the net carrying values for the six months ended June 30, 2010 and 2009:

NOTE 9. 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, term auction facility (“TAF”) advances 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. TAF advances are collateral backed short-term loans with the Federal Reserve. 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.

The following table represents the composition of short-term borrowings at:


	June 30, 2010		December 31, 2009
*(dollars in thousands)*

Securities sold under repurchase agreements, retail	$	44,496	$	44,935
Federal Home Loan Bank advances		51,750		51,300

Total	$	96,246	$	96,235

Long-term debt instruments are for original terms greater than one year and may be comprised of wholesale REPOs, FHLB advances, junior subordinated debt securities and trust preferred securities. Long-term REPOs and FHLB advances have the same collateral requirements as their short-term equivalents. Junior subordinated debt securities and trust preferred securities are structured to meet regulatory requirements for inclusion in risk-based capital components.

S&T had total long-term borrowings outstanding of $62.2 million at a fixed rate and $68.7 million at a variable rate at June 30, 2010.

S&T had total borrowings at June 30, 2010 and December 31, 2009 at the FHLB of Pittsburgh of $91.8 million and $136.9 million, respectively. Total borrowings consisted of short-term and long-term borrowings of $51.7 million and $40.1 million at June 30, 2010 and $51.3 million and $85.6 million at December 31, 2009. At June 30, 2010, S&T had a maximum borrowing capacity of $1.2 billion with the FHLB of Pittsburgh.

NOTE 10. EMPLOYEE BENEFITS

S&T Bank maintains a defined benefit pension plan (the “Plan”) covering substantially all employees hired prior to January 1, 2008. The benefits are based on years of service and the employee’s 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 2009 and no contributions are required to be made for 2010 at this time. The expected long-term rate of return on plan assets is 8.00 percent.

The following table summarizes the components of net periodic pension expense for the Plan:

NOTE 11. 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&T’s exposure to credit loss, in the event the customer does not satisfy the terms of the agreement, equals the contractual amount of the obligation less the value of any collateral. 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 an annual 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&T’s allowance for lending-related commitments including unfunded commercial real estate, commercial and industrial term loan commitments and letters of credit totaled $3.5 million at June 30, 2010 and $4.2 million at December 31, 2009. 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 counterparties.

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

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 pending will not have a material adverse effect on its consolidated financial position.

NOTE 12. EARNINGS PER COMMON SHARE

Basic earnings per common share (“EPS”) is calculated by dividing net income attributable 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&T’s outstanding stock options and restricted stock. Excluded from the calculation were 1,008,546 shares of anti-dilutive stock options, common stock warrants of 517,012 shares and 5,204 shares of restricted stock for the three months ended June 30, 2010 and 1,008,546 shares of anti-dilutive stock options, common stock warrants of 517,012 shares and 2,040 shares of restricted stock for the six months ended June 30, 2010. For the three and six months ended June 30, 2009, basic EPS equals diluted EPS due to S&T’s net loss position.

A reconcilement of the weighted average common shares outstanding used to calculate basic net income (loss) per common share and diluted net income (loss) per common share follows:


	Three Months Ended June 30,		Six Months Ended June 30,
	2010	2009	2010	2009

NOTE 13. SEGMENTS

S&T operates in three reportable operating segments: Community Banking, Wealth Management and an Insurance Agency.

The Community Banking segment offers services which include accepting demand deposit accounts and certificates of deposit, originating commercial and consumer loans, providing letters of credit and credit card services.

The Wealth Management segment offers discount brokerage services, services as executor and trustee under wills and deeds, guardian and custodian of employee benefits and other trust and brokerage services, as well as a registered investment advisor that manages private investment accounts for individuals and institutions.

The Insurance Agency segment includes a full-service insurance agency offering commercial property and casualty insurance, group life and health coverage, employee benefit solutions and personal insurance lines.

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

Management’s Discussion and Analysis (“MD&A”) represents an overview of the consolidated results of operations and financial condition of S&T and highlights material changes to the financial condition and results of operations at and for the three and six months ended June 30, 2010. MD&A should be read in conjunction with the consolidated financial statements and notes thereto. The results of operations reported within are not necessarily indicative of results to be expected in future periods.

Important Note Regarding Forward-Looking Statements

This Quarterly Report on Form 10-Q contains or incorporates statements that S&T believes are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These statements generally relate to S&T’s financial condition, results of operations, plans, objectives, future performance or business. They usually can be identified by the use of forward-looking language such as “will likely result,” “may,” “are expected to,” “is anticipated,” “estimate,” “forecast,” “projected,” “intends to” or other similar words. You should not place undue reliance on these statements, as they are subject to risks and uncertainties, including but not limited to, those described in this Form 10-Q or the documents incorporated by reference. When considering these forward-looking statements, you should keep in mind these risks and uncertainties, as well as any cautionary statements we may make. Moreover, you should treat these statements as speaking only as of the date they are made and based only on information actually known to us at that time. We undertake no obligation to update publicly any forward-looking statements, whether as a result of new information, future events or otherwise.

These forward-looking statements are based on current expectations, estimates and projections about S&T’s business, management’s beliefs and assumptions made by management. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions (“Future Factors”), which are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or forecasted in these forward-looking statements.

Future Factors include:

•

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

•

Critical Accounting Policies and Judgments

S&T’s Consolidated Financial Statements are prepared based upon the application of certain critical accounting policies including, securities valuation, allowance for loan losses, goodwill and other intangible assets and income taxes. These policies require numerous estimates and strategic or economic assumptions that may prove inaccurate or subject to variations and may significantly affect S&T’s reported results and financial position for the period or in future periods. Changes in underlying factors, assumptions or estimates in any of these areas could have a material impact on S&T’s future financial condition and results of operations.

There have been no significant changes in S&T’s critical accounting policies since December 31, 2009. S&T’s critical accounting policies are presented in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations in S&T’s Annual Report on Form 10-K for the fiscal year ended December 31, 2009, as filed with the Securities and Exchange Commission (“SEC”) on February 26, 2010.

Overview

S&T is a financial holding company with its headquarters located in Indiana, Pennsylvania with assets of approximately $4.1 billion at June 30, 2010. S&T provides a full range of financial services through a branch network of 53 offices located in Allegheny, Armstrong, Blair, Butler, Cambria, 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 investment management and administration; corporate services and other fiduciary services. S&T earns revenue primarily from interest on loans, security investments and fees charged for financial services provided to our customers. Offsetting these revenues are the cost of deposits and other funding sources, provision for loan losses as well as other operating costs such as: salaries and employee benefits, occupancy, data processing expenses and tax expense. S&T’s strategic plan to deliver profitable growth to our shareholders includes: increasing loans and core deposits with sufficient interest rate spreads, controlling loan delinquency and loan losses, controlling operating expenses and expanding the business through new de novo branching, mergers and acquisitions, introduction of new products and services and expansion of our products and services provided to our existing customers. S&T’s common stock trades on the Nasdaq Global Select Market under the symbol “STBA.”

Net income available to common shareholders for the first six months of 2010 was $17.6 million resulting in diluted earnings per common share of $0.63 compared to a $13.3 million net loss and $(0.48) diluted earnings per share in the first six months of 2009. The increase in net income was primarily driven by a reduction in the provision for loan losses. During the first six months of 2010, a provision of $13.6 million was recorded compared to $53.6 million in the first six months of 2009. The reduction in provision is a result of improved asset quality measures and positive trends in S&T’s non-performing loan portfolio. Net interest margin remains strong at 4.03% for the first six months of 2010 compared to 3.84% in the comparable period of 2009; a result of favorable deposit and borrowing repricing.

Asset quality will continue to be the primary driver of our results for the remainder of fiscal 2010. 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 continually assesses our balance sheet, capital, liquidity and operation infrastructures in order to be positioned to take advantage of internal or acquisition growth.

Recent Regulatory Developments

Dodd-Frank Wall Street Reform and Consumer Protection Act

On July 21, 2010, the President signed into law the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”). The Dodd-Frank Act increases regulation and oversight and imposes restrictions on the ability of firms within the industry, including S&T, to conduct business in accordance with historical practices. Among other things, the Dodd-Frank Act:

•

Establishes a Financial Stability Oversight Council, which will be responsible for identifying and monitoring systemic risks posed by financial firms’ activities and practices.

•

Impacts the ability of companies to invest for their own account (the so-called “Volcker rule”).

•

Creates a Consumer Financial Protection Bureau, housed within the Federal Reserve, to take over responsibility for the principal federal consumer protection laws, such as the Truth in Lending Act, the Equal Credit Opportunity Act, the Real Estate Settlement Procedures Act and the Truth in Saving Act, among others. Institutions such as S&T Bank, which have assets of $10 billion or less, will continue to be supervised in this area by their primary federal regulators (in the case of S&T, the Federal Deposit Insurance Corporation (“FDIC”)).

•

Includes mortgage reform provisions that would require all lenders to consider a customer’s ability to repay, would make more loans subject to the higher-cost loans rules, and impose new disclosures and certain other provisions relating to appraisals and servicing of loans.

•

Expands the reach of the affiliate transaction rules in Section 23A of the Federal Reserve Act to apply to securities lending, repurchase agreement and derivatives activities that S&T may have with an affiliate.

•

Clarifies standards for federal preemption of state laws related to federally chartered institutions and their subsidiaries in the consumer protection area.

•

Provides for new disclosure and other requirements related to executive compensation and corporate governance. Among other things, financial institutions with $1 billion or more in assets are prohibited from rewarding their executive officers, employees, directors and principal shareholders with incentive-based compensation arrangements that encourage “inappropriate risks” and are required to report all incentive-based compensation arrangements to the appropriate federal regulator.

•

Requires the federal banking agencies to ensure that the same minimum leverage and risk-based capital requirements imposed on insured depository institutions are imposed on holding companies and certain other companies on a consolidated basis, including S&T. Going forward, hybrid capital instruments, such as trust preferred securities, can no longer be included as a component of Tier 1 capital, although already outstanding trust preferred securities can continue to be counted as Tier 1 capital by companies like S&T with consolidated assets of up to $15 billion. The federal banking agencies are also required to develop additional capital requirements to address the risk of an institution’s activities to that institution and to other private and public stakeholders in the event of adverse performance, disruption or failure of the institution.

•

Directs the Federal Reserve to issue rules that are expected to limit debit card interchange fees and debit network practices.

•

Makes substantial changes to the processes by which asset-backed securities are created, rated and sold, including a requirement that lenders retain a portion of the credit risk for any asset transferred or sold.

•

Increases the minimum reserve ratio for the FDIC’s Deposit Insurance Fund from 1.15% to 1.35% and changes the basis for determining deposit insurance premiums from deposits to assets.

•

Permanently increases deposit insurance coverage to $250,000 per account and allows depository institutions to pay interest on checking accounts.

Many of the provisions of the Dodd-Frank Act will not become effective until a year or more after its enactment and the adoption and effectiveness of implementing regulations. As a result, we cannot predict the ultimate impact of the Dodd-Frank Act on S&T at this time.We believe that it could increase costs and limit our ability to pursue business opportunities in an efficient manner, of which could materially and adversely affect our business, financial condition and results of operations. Nor can we predict the impact or substance of other future legislation or regulation.

Explanation of Use of Non-GAAP Financial Measures

In addition to the results of operations presented in accordance with GAAP, S&T 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. S&T believes these non-GAAP financial measures provide information useful to investors in understanding our underlying operational performance and our business and performance trends as they facilitate comparisons with the performance of others in the financial services industry. Although S&T believes that these non-GAAP financial measures enhance investors’ understanding of S&T’s business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP.

We believe 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 (Loss) is reconciled to net interest income adjusted to a fully taxable equivalent basis in the table below for the three months ended June 30, 2010 and page 31 for the six months ended June 30, 2010.

Operating revenue is the sum of net interest income and noninterest income, less security gains. In order to understand the significance of net interest income to S&T’s business and operating results, S&T 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 June 30, 2010 Compared to

Three Months Ended June 30, 2009

Net Income

Net income available to common shareholders was $7.9 million or $0.28 diluted earnings per share for the second quarter of 2010 as compared to a net loss available to common shareholders of $10.2 million or $(0.37) diluted earnings per share for the same period of 2009. The increase in net income was primarily the result of a significantly lower provision for loan losses and a reduction in noninterest expenses in the second quarter of 2010. The common return on average assets was 0.76 percent for the three months ended June 30, 2010, as compared to (0.95) percent for the three months ended June 30, 2009. The common return on average equity was 5.60 percent for the three months ended June 30, 2010 compared to (7.44) percent for the same period of 2009.

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 volume of interest-earning assets and interest-bearing liabilities and changes in interest yields and rates. Therefore, maintaining consistent spreads between interest-earning assets and interest-bearing liabilities is significant to our financial performance because net interest income comprised 77 percent and 76 percent of operating revenue (net interest income plus noninterest income, excluding security gains) in the second quarter of 2010 and 2009, respectively. The level and mix of interest-earning assets and funds are continually monitored by S&T’s Asset and Liability Committee (“ALCO”) in order to mitigate the interest-rate sensitivity and liquidity risks of the balance sheet. A variety of ALCO strategies were implemented, within prescribed ALCO risk parameters, to maintain an acceptable net interest margin given the challenges of the current interest rate environment.

Net Yield on Interest-earning Assets⁽¹⁾					4.05	%					3.86	%


Net Interest Income⁽¹⁾			$	37.8					$	37.9

⁽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.

The net interest margin on a fully taxable equivalent basis was 4.05 percent for the second quarter of 2010 as compared to 3.86 percent in the same period of 2009. Net interest income decreased only $0.1 million in the second quarter of 2010 compared to the same period of 2009 despite a $190 million decrease in average interest-earning assets. The average rate on interest-earnings assets declined 10 basis points while the rate on total interest-bearing liabilities decreased 39 basis points. Positively affecting net interest income was a $78.6 million increase in average net free funds during the three months ended June 30, 2010 as compared to the same period of 2009. Average net free funds are the excess of demand deposits, other noninterest-bearing liabilities and shareholders’ equity over nonearning assets. The increase is due to the low interest rate environment, our marketing efforts for new demand accounts and corporate cash management services and participation in the Transaction Account Guarantee (“TAG”) Program.

⁽¹ ⁾ 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.

⁽²⁾ Tax-exempt income is on a fully taxable equivalent basis using the statutory federal corporate income tax rate of 35 percent for 2010 and 2009.

Provision for Loan Losses

The provision for loan losses is determined based on management’s estimates of the appropriate level of allowance for loan losses needed to absorb probable losses inherent in the existing loan portfolio, after giving consideration to charge-offs and recoveries for the period. The provision for loan losses was $9.1 million for the second quarter of 2010 compared to $32.2 million for the second quarter of 2009. Changes within the allowance for loan loss model are directionally consistent with the decrease in nonperforming loans, loan charge-off levels and impaired loans requiring specific reserves.

S&T has experienced an overall improvement in asset quality measures from the second quarter of 2009. During the second quarter of 2010, net charge-offs of $18.2 million were recorded compared to $34.2 million in the comparable period in 2009. Of the $18.2 million in charge-offs, approximately $13.0 million had previously established specific reserves. Specific reserves for impaired loans were $8.0 million at June 30, 2010 compared to $15.0 million at June 30, 2009. Overall, S&T’s nonperforming loan formation has slowed compared to 2009. Refer to the Allowance for Loan Losses section of this MD&A for further details.

income relates to a significant amount of refinances that occurred in the second quarter of 2009, as customers took advantage of low interest rates, and temporary impairment charges for mortgage servicing rights of $0.3 million, which were recorded in the second quarter of 2010. The increase in debit and credit card fees of $0.6 million is primarily a result of a change in presentation of gross point of sale fees and expenses compared to a net presentation in prior periods.

Noninterest expense decreased by $7.0 million during the three months ended June 30, 2010 compared to the three months ended June 30, 2009. Salaries and employee benefit expense decreased $0.9 million which was primarily attributable to mark-to-market accounting adjustments for the deferred compensation plan. Joint venture amortization decreased by $1.8 million related to impairment charges recorded on low income housing tax credit projects (“LIHTC”) in the second quarter of 2009. FDIC assessment decreased $2.0 million due to a one-time special assessment that occurred in the second quarter of 2009. The decrease in other noninterest expenses of $2.3 million related to a reduction in the reserve for unfunded loan commitments due to a decrease in the amount of unfunded commitments in the second quarter of 2010.

Federal Income Taxes

Federal income tax expense was $3.9 million for the quarter ended June 30, 2010 compared to a $9.3 million benefit for the quarter ended June 30, 2009. The benefit of $9.3 million was a result of a pretax loss of $17.9 million in the second quarter of 2009.

The annual effective tax rate for the second quarter of 2010 applied to pretax income was 29.25 percent. The rate is less than the 35 percent statutory rate due to benefits resulting from tax-exempt interest, excludable dividend income and the tax benefits associated with LIHTC and Federal Historic Tax Credit projects. The effective tax rate for the second quarter of 2009 was (51.75) percent due to the consistent level of tax benefits that reduced S&T’s tax rate below the 35 percent statutory rate, coupled with a relatively low level of annual pretax income.

The increase in net income was primarily the result of a significantly lower provision for loan losses, no significant security impairments and a decrease in noninterest expenses for the six months ended June 30, 2010. The common return on average assets was 0.86 percent for the six months ended June 30, 2010, as compared to (0.62) percent for the six months ended June 30, 2009.

For the first six months of 2010, S&T experienced net loan charge-offs of $19.2 million compared to net loan charge-offs of $38.4 million for the first six months of 2009. Overall, asset quality measures have improved from the first six months of 2009. Non-performing loan formation has slowed significantly compared to 2009 with only three relationships exceeding $1.0 million moving into nonperforming status in the first six months of 2010. These relationships have been reserved against or charged off to reflect the fair market value of the collateral expected to be received. Refer to the Allowance for Loan Losses section of this MD&A for further details.

Noninterest income increased $3.4 million to $22.9 million in the first six months of 2010 as compared to the first six months of 2009. S&T recognized $0.3 million of gains on available-for-sale securities in the six months ended June 30, 2010 as compared to $2.5 million of losses for OTTI of 3 equity securities in the same period of 2009. The increase of $0.5 million in insurance fees is primarily driven by higher annual bonus commission income received in the first quarter of 2010 compared to the prior year based

upon positive trends in loss rates. The decrease in mortgage banking income is due to a significant amount of refinances that occurred in the first six months of 2009, as customers took advantage of low interest rates. The $0.8 million increase in other noninterest income is primarily related to mark-to-market accounting adjustments relating to the deferred compensation plan.

Noninterest expense decreased by $4.5 million during the six months ended June 30, 2010 compared to the six months ended June 30, 2009. Joint venture amortization decreased during the first six months of 2010 due to the impairment for LIHTC recorded in 2009, FDIC assessment decreased by $2.7 million primarily due to a special assessment received in 2009 and the $2.1 million decrease in other noninterest expense primarily related to a reduction in the reserve for unfunded loan commitments. These decreases were offset with an increase of $2.2 million in legal expenses that occurred in the first six months of 2010.

Federal Income Taxes

Federal income tax expense was $7.5 million for the six months ended June 30, 2010 compared to a $9.1 million benefit for the six months ended June 30, 2009 due to a pretax loss of $19.6 million.

The annual effective tax rate for the six months ended of 2010 applied to pretax income was 26.54 percent. The rate is less than the 35 percent statutory rate due to benefits resulting from tax-exempt interest, excludable dividend income and the tax benefits associated with LIHTC and Federal Historic Tax Credit projects. The effective tax rate for the six months ended June 30, 2009 was (46.46) percent due to a consistent level of tax benefits that reduced S&T’s tax rate below the 35 percent statutory rate, coupled with relatively low level of annual pretax income.

Financial Condition

Loan growth has been challenging in our market in the first six months of 2010. Total loans at June 30, 2010 remain relatively consistent with total loans at December 31, 2009 with a slight decrease of $13.8 million of consumer loans offset by an increase of $6.1 million of commercial loans. Securities have decreased $38.7 million from December 31, 2009 as a result of maturities. Deposits remain stable at $3.3 billion as of June 30, 2010 and December 31, 2009.

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 annually approved by the S&T Board of Directors and administered through ALCO and the Treasury function of S&T Bank.

Securities and other investments decreased by $38.7 million as of June 30, 2010 compared to December 31, 2009. The decreases relates to maturities of debt securities of $79.3 million offset by purchases of $40.6 million.

S&T’s policy for security classification includes obligations of U.S. government corporations and agencies, collateralized mortgage obligations of U.S. government corporations and agencies, mortgage-backed securities of U.S. government corporations and agencies, obligations of states and political subdivisions and marketable equity securities as available-for-sale. The marketable equity securities portfolio is primarily comprised of bank stocks. On a quarterly basis, management evaluates the securities portfolios for OTTI according to the respective accounting literature requiring investments to be reported at estimated fair value. During the first six months of 2010, there was no significant investment impairment charges recorded. The performance of the debt and equity securities markets could generate further impairment in future periods requiring realized losses to be reported.

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 the borrower’s 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 the S&T Board of Directors.

Loans decreased $7.7 million as of June 30, 2010 as compared to December 31, 2009. Minimal loan growth was experienced within the commercial portfolio and a slight decline occurred in the consumer portfolio. This is a result of less demand in our market area resulting from the current economic climate.

Commercial loans, including commercial real estate, commercial and industrial and construction comprised 73 percent of the loan portfolio as of June 30, 2010 and December 31, 2009. Although commercial loans can have a relatively higher risk profile, management believes these risks are mitigated through active portfolio management, underwriting and continuous review. The commercial real estate and construction portfolio had $356.8 million or 11 percent of total loans that involved projects outside of Pennsylvania. Generally, these loans are with existing local customers. The decline in the economic environment has been significantly higher in various parts of the country than in Pennsylvania. Accordingly, the out-of-state portfolio is experiencing higher credit stress and has been the subject of considerable management focus and review. The loan-to-value policy guidelines for commercial real estate loans is generally 65-85 percent. Variable rate commercial loans were 52 percent of the commercial loan portfolio at June 30, 2010 and 50 percent at December 31, 2009.

Home equity and residential mortgage and loans comprised 24 percent of the loan portfolio at June 30, 2010 and December 31, 2009. 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&T’s conservative mortgage lending policies for portfolio loans, which require a maximum term of 20 years for fixed rate mortgages. Balloon payment 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 consisting of S&T residential first mortgage and home equity second mortgage are also available to credit worthy 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 six months ended June 30, 2010 and 2009, S&T sold $37.7 million and $86.0 million, respectively, of 1-4 family mortgages and currently services $278.3 million of secondary market mortgage loans to Fannie Mae at June 30, 2010. Loans sold to Fannie Mae decreased from the prior year as rates declined substantially in early 2009 resulting in a significant amount of mortgage refinances. S&T intends to continue to sell longer-term loans to Fannie Mae in the future, especially during periods of lower interest rates.

Loan underwriting standards for S&T are established by a formal policy and are subject to the periodic review and approval by the S&T Board of Directors. During 2009, S&T implemented or enhanced various new policies and procedures including: monitoring, risk ratings, stress testing and compliance for the area of commercial lending.

S&T offers a variety of unsecured and secured consumer loan and credit card products. Loan-to-value policy guidelines for direct loans are 90–100 percent of invoice for new automobiles and 80–90 percent of National Automobile Dealer Association (“NADA”) value for used automobiles.

Allowance for Loan Losses

Problem loans are identified and continually monitored through detailed reviews of specific commercial loans, and the analysis of delinquency and charge-off levels of consumer loan portfolios. Management evaluates the degree of loss exposure for loans on a continuous basis through a formal allowance for loan loss policy as administered by S&T Bank’s Credit Administration Department and various management and director committees. Updates are presented by management to the S&T Board of Directors as to the status of loan quality. Charged-off and recovered loan amounts are applied to the allowance for loan losses. The allowance for loan losses is increased through a charge to current earnings through the provision for loan losses, based upon management’s assessment of the adequacy of the allowance for loan losses. A quantitative analysis is utilized to support the adequacy of the allowance for loan losses. This analysis includes a review of the historical charge-off rates for all loan categories as well as fluctuations and trends in various risk factors that have occurred within the portfolio’s economic life cycle. The analysis also includes assessment of qualitative factors such as credit trends, unemployment trends, vacancy trends, loan growth and the degree of variable interest rate risk. Should any of the factors considered by management in evaluating the adequacy of the allowance for loan losses change, S&T’s estimate of loan losses could also change.

Significant to this analysis and assessment is the loan portfolio composition of 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 risk rating process 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 allowance for loan losses.

S&T has a charge-off policy within its general lending policy. The charge-off policy has two components, retail and commercial.

S&T BANCORP, INC. AND SUBSIDIARIES

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS -

Two types of retail loans are included in the charge-off policy. The first type is unsecured or secured with non real estate. These loans are evaluated for a charge at 90 days past due. Unsecured loans are fully charged-off. If the loan is secured with non real estate, it will be charged down to the value of the collateral less the estimated cost to sell. If the collateral is repossessed and remains unsold for 120 days the carrying value will be completely charged-off. The second type is loans secured by real estate. These loans will be evaluated for a charge at 90 days past due. The loan will be charged down to the value of the collateral less the estimated 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. The bank may elect to recognize a partial charge-off when management has determined that the value of collateral is less than the then remaining balance. 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; and

•

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

The following table presents changes in the allowance for loan losses for the six months ended June 30:

Allowance for loan losses to total loans	1.59	%	1.67	%
Allowance for loan losses to nonperforming loans	70	%	81	%

The allowance for loan losses at June 30, 2010 was $54.0 million, a decrease of $3.9 million from June 30, 2009. Included in the allowance for loan losses at June 30, 2010 is $8.0 million of specific reserves compared to $15.0 million at June 30, 2009. S&T has experienced improving asset quality metrics in the first six months of 2010, including a slowing in nonperforming loans (“NPL”) formation. During the first six months of 2010, S&T recorded net charge-offs of $19.2 million, which related primarily to six credits, all of which had previously established specific reserves. Additionally, only three relationships greater than $1.0 million moved to NPL status during the first six months of 2010 including a $2.2 million multi-family apartment complex, a $1.4 million hotel property and a $1.8 residential mortgage. For each relationship, an impaired loan analysis was completed and specific reserves were established of $1.4 million, $0.2 million and $0.7 million, respectively. Management believes these relationships have been adequately reserved as determined by the quarterly impairment analysis performed by the Credit Administration Department.

S&T’s allowance for lending-related commitments is computed using a methodology similar to that used to determine the allowance for loan losses. 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 $3.5 million at June 30, 2010 as compared to $4.2 million at December 31, 2009. The decrease relates to 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.

Total Deposits	$	3,297,196	$	3,304,541	$	(7,345	)

Deposits are the primary source of funds to S&T. Management believes that the S&T deposit base is stable and that S&T has the ability to attract new deposits, mitigating a funding dependency on other more volatile sources. Certificates of deposit of $100,000 and over were 12 percent of total deposits at June 30, 2010 and December 31, 2009, and primarily represent deposit relationships with local customers in our market area. S&T had $93.8 million and $109.8 million of brokered retail certificates of deposit outstanding at June 30, 2010 and December 31, 2009, 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 June 30, 2010, the CDARS certificates of deposit were primarily reciprocal totaling $67.2

Total Borrowings	$	227,193	$	272,748	$	(45,555	)

Borrowings are an additional source of funding for S&T. Total borrowings decreased $45.6 million from December 31, 2009 due to the maturity of $55.2 million of long-term borrowings of which only $10.0 million were replaced with new long-term borrowings. Overall, borrowings decreased as a result of relatively unchanged loan volume, lower securities from December 31, 2009 and a stable deposit base.

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. Customer deposits are an important source of liquidity which depends on the confidence of those customers in S&T supported by its 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&T’s 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.

During 2010 liquidity improved due to decreases in loan and security balances, stable deposit levels and a larger borrowing capacity at the FHLB which resulted from reduced borrowings.

Shareholders’ equity increased $12.9 million at June 30, 2010 compared to December 31, 2009. S&T had net income available to common shareholders of $17.6 million and dividends declared to common shareholders were $8.3 million for the six months ended June 30, 2010. Also affecting capital was an increase of $1.1 million due to the issuance of treasury stock, an increase of $1.7 million in unrealized gains on securities available-for-sale, net of tax, which is included in other comprehensive income, offset by preferred dividends and amortization of $2.7 million.

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.

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 any 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 June 30, 2010, S&T had not issued any securities pursuant to the shelf registration statement.

On January 16, 2009, S&T completed a $108.7 million capital raise as a participant in the Capital Purchase Program (the “CPP”). S&T used the funds received from the issuance of the Series A Preferred Stock and warrants to reduce S&T’s overnight borrowings at the FHLB which had the effect of increasing S&T’s liquidity for lending activities.

Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ALCO monitors and manages interest rate sensitivity through gap, rate shock analysis and simulations and economic value of equity (“EVE”) in order to avoid unacceptable earnings fluctuations due to interest rate changes. S&T’s 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, mortgage-backed securities and collateralized mortgage obligations, and classifying the demand, money market and savings balances by degree of interest rate sensitivity. The gap and cumulative gap represent the net position of assets and liabilities subject to repricing in specified 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:

Rate Sensitive Assets/Rate Sensitive Liabilities	June 30, 2010	December 31, 2009

Cumulative 6 months	1.16	1.12
Cumulative 12 months	1.24	1.10

S&T’s one-year repricing gap at June 30, 2010 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 an increasing interest rate environment, more assets than liabilities will increase in rate. This situation could result in an increase to our interest rate spreads, net interest income and operating income. Conversely, 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 to our 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 (demand, NOW, 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 analysis more useful than gap analysis alone.

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.


	Immediate Change in Rates
Percent Change to Pretax Net Interest Income	+300 bps		-300 bps

June 30, 2010	12.12	%	(6.29	)%
December 31, 2009	8.16	%	(6.93	)%

The impact to pretax net interest income in the +/-300 basis point rate shocks for June 30, 2010 is consistent with having an asset sensitive balance sheet. When comparing the +300 basis point rate shock results in June 30, 2010 to December 31, 2009, the percent change to net interest income has improved because the balance sheet has become more asset sensitive. When comparing the
-300 basis point rate shock results in June 30, 2010 to December 31, 2009, the percent change to net interest income is relatively unchanged.

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 June 30, 2010. 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 SEC’s 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 company’s 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 June 30, 2010, 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

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 June 30, 2010 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
