NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE A - BASIS OF PRESENTATION

The accompanying unaudited condensed 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 nine-month period ended September 30, 2009 are not necessarily indicative of the results that may be expected for the year ending December 31, 2009. S&T operates within one business segment, community banking, providing a full range of services to individual and corporate customers. The condensed consolidated balance sheet as of December 31, 2008 has been extracted from the audited financial statements included in S&T’s 2008 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, 2008, as filed with the Securities and Exchange Commission (“SEC”) on February 27, 2009.

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. Actual results could differ from those estimates.

The condensed 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 – 50 percent of the outstanding common stock of investees are accounted for using the equity method of accounting.

For the nine month periods ended September 30, 2009 and 2008, interest paid was $30,214,000 and $44,636,000, respectively. Income taxes paid during the first nine months of 2009 were $5,338,000 compared to $17,928,000 for the same period of 2008.

NOTE B - NET INCOME PER SHARE

Earnings per common share is calculated after recognition of preferred stock dividends and accretion. S&T’s basic net income per common share is calculated as net income divided by the weighted average number of shares outstanding. For diluted net income per common share, net income, which is net of preferred dividends and accretion, is divided by the weighted average number of shares outstanding plus the incremental number of shares added as a result of converting common stock equivalents, calculated using the treasury stock method. S&T’s common stock equivalents consist of outstanding stock options, restricted stock and warrants. Excluded from the calculation were anti-dilutive stock options of 1,188,000 shares and 551,000 shares for the nine months ended September 30, 2009 and 2008, respectively.

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


	Three Months Ended September 30,		Nine Months Ended September 30,
	2009	2008	2009	2008
Weighted average shares outstanding (basic)	27,633,742	27,416,807	27,654,570	25,764,275
Impact of common stock equivalents	61,463	185,409	—	170,370

Weighted average shares outstanding (diluted)	27,695,205	27,602,216	27,654,570	25,934,645

NOTE C - RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In December 2007, FASB issued SFAS No. 141R (ASC 805-10), “Business Combinations,” and SFAS No. 160 (ASC 810-10), “Noncontrolling Interest in Consolidated Financial Statements.” SFAS No. 141R (ASC 805-10) and No. 160 (ASC 810-10) require most identifiable assets, liabilities, noncontrolling interest, and goodwill acquired in a business combination to be recorded at “full fair value” and require noncontrolling interests (previously referred to as minority interests) to be reported as a component of equity, which changes the accounting for transactions with noncontrolling interest holders. SFAS No. 141R (ASC 805-10) and No. 160 (ASC 810-10) are effective for periods beginning on or after December 15, 2008, and earlier adoption is prohibited. SFAS No. 141R (ASC 805-10) will be applied to all business entities and SFAS No. 160 (ASC 810-10) will be applied prospectively to all noncontrolling interests, including any that arose before the December 15, 2008 effective

date. The adoption of SFAS No. 141R (ASC 805-10) and No. 160 (ASC 810-10) did not have a significant impact on S&T’s consolidated financial position and results of operations.

In March 2008, FASB issued SFAS No. 161 (ASC 815-10), which amends SFAS No. 133 (ASC 815-10) “Accounting for Derivative Instruments and Hedging Activities.” SFAS No. 161 (ASC 815-10) requires companies with derivative instruments to disclose information about how and why a company uses derivative instruments, how derivative instruments and related hedged items are accounted for under SFAS No. 133 (ASC 815-10), and how derivative instruments and related hedged items affect a company’s financial position, financial performance and cash flows. SFAS No. 161 (ASC 815-10) is effective prospectively for annual or interim reporting periods beginning after November 15, 2008. The adoption of SFAS No. 161 (ASC 815-10) did not have a significant impact on S&T’s consolidated results of operations or financial position.

In June 2008, FASB issued FASB Staff Position (“FSP”) Emerging Issues Task Force (“EITF”) 03-6-1 (ASC 260-10) “Determining Whether Instruments Granted in Share-Based Payment Transactions are Participating Securities.” FSP EITF 03-6-1 (ASC 260-10) clarifies whether instruments, such as restricted stock, granted in share-based payments are participating securities prior to vesting. Such participating securities must be included in the computation of earnings per share under the two-class method as described in SFAS No. 128 (ASC 260-10), “Earnings per Share.” FSP EITF 03-6-1 (ASC 260-10) requires companies to treat unvested share-based payment awards that have non-forfeitable rights to dividend or dividend equivalents as a separate class of securities in calculating earnings per share. FSP EITF 03-6-1 (ASC 260-10) is effective for financial statements issued for fiscal years and interim periods beginning after December 15, 2008, and requires a company to retrospectively adjust its earning per share data. The adoption of FSP EITF 03-6-1 (ASC 260-10) did not have a significant impact on S&T’s consolidated results of operations or earnings per share.

In April 2009, FASB issued FSP FAS No. 107-1 (ASC 825-10), “Interim Disclosures About Fair Value of Financial Instruments” which amends SFAS No. 107 (ASC 825-10), “Disclosures about Fair Value of Financial Instruments” to require disclosures about fair value of financial instruments for interim reporting periods of publicly traded companies as well as in annual financial statements. This FSP also amends Accounting Principles Board Opinion No. 28 (ASC 270-10), “Interim Financial Reporting”, to require those disclosures in summarized financial information at interim reporting periods. FSP FAS 107-1 (ASC 825-10) is effective for interim reporting periods ending after June 15, 2009. The adoption of this FSP in the second quarter of 2009 did not have a significant impact on S&T’s consolidated results of operations or financial position.

In April 2009, FASB issued FSP No. 115-2 and No. 124-2 (ASC 320-10), “Recognition and Presentation of Other-Than-Temporary Impairments,” which amends existing guidance for determining whether impairment is other-than-temporary for debt securities. This FSP requires an entity to assess whether it intends to sell, or it is more likely than not that it will be required to sell a security in an unrealized loss position before recovery of its amortized cost basis. If either of these criteria is met, the entire difference between amortized cost and fair value is recognized in earnings. For securities that do not meet the aforementioned criteria, the amount of impairment recognized in earnings is limited to the amount related to credit losses, while impairment related to other factors is recognized in other comprehensive income. Additionally, this FSP expands and increases the frequency of existing disclosures about other-than-temporary impairments for debt and equity securities. This FSP is effective for interim and annual reporting periods ending after June 15, 2009, with early adoption permitted for periods ending after March 15, 2009. The adoption of this FSP in the second quarter of 2009 did not have a significant impact on S&T’s consolidated results of operations or financial position.

In April 2009, FASB issued FSP FAS No. 157-4 (ASC 820-10), “Determining Fair Value When the Volume and Level of Activity for the Asset or Liability has Significantly Decreased and Identifying Transactions that are Not Orderly” which provides additional guidance for estimating fair value in accordance with SFAS No. 157 (ASC 820-10) “Fair Value Measurement” when the volume and level of activity for the asset or liability have significantly decreased. This FSP also includes guidance on identifying circumstances that indicate a transaction is not orderly. FSP FAS No. 157-4 (ASC 820-10) is effective for interim and annual reporting periods ending after June 15, 2009 and should be applied prospectively. The adoption of this FSP in the second quarter of 2009 did not have a significant impact on S&T’s consolidated results of operations or financial position.

In May of 2009, FASB issued SFAS No. 165 (ASC 855-10), “Subsequent Events” which establishes principles and requirements for subsequent events. This statement requires management to evaluate subsequent events through the date the financial statements are either issued or available to be issued. Companies are required to disclose the date through which subsequent events have been evaluated. SFAS No. 165 (ASC 855-10) is effective for interim or annual financial periods ending after June 15, 2009. The adoption of SFAS No. 165 (ASC 855-10) in the second quarter of 2009 did not have a significant impact on S&T’s consolidated results of operations or financial position.

In June of 2009, FASB issued SFAS No. 166 (ASC Topic 860), “Accounting for Transfers of Financial Assets” which amends SFAS No. 140 (ASC 860-10). “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities”. This statement 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. SFAS No. 166 (ASC Topic 860), is effective as of the beginning of the first annual and interim reporting period that begins after November 15, 2009. S&T does not anticipate that the adoption of SFAS No. 166 (ASC Topic 860), will have a significant impact on S&T’s consolidated results of operations or financial position.

In June of 2009, FASB issued SFAS No. 167 (ASC Topic 810), “Amendments of FASB Interpretation No. 46(R)” which amends FIN 46(R) (ASC 810-10) to require former QSPEs to be evaluated for consolidation and also changes the approach to determining a variable interest entity’s (“VIE”) primary beneficiary and requires companies to more frequently reassess whether they must consolidate VIEs. SFAS No. 167 (ASC Topic 810) is effective as of the beginning of the first annual and interim reporting period that begins after November 15, 2009. S&T does not anticipate that the adoption of SFAS No. 167 (ASC Topic 810) will have a significant impact on S&T’s consolidated results of operations or financial position.

In July of 2009, FASB issued SFAS No. 168 (ASC 105-10), “The FASB Accounting Standards Codification and Hierarchy of Generally Accepted Accounting Principles”. The codification will become the exclusive authoritative reference for U.S. GAAP for use in financial statements issued for interim and annual periods ending after September 15, 2009. The adoption of SFAS No. 168 (ASC 105-10) in the third quarter of 2009 did not have a significant impact on S&T’s consolidated results of operations or financial position.

In December of 2008, FASB issued FSP No. 132(R) (ASC 715-20-65-2), “Employers’ Disclosures about Postretirement Benefit Plan Assets,” to provide guidance on an employer’s disclosures about plan assets of a defined benefit pension or other postretirement plan. The FSP requires more disclosure about how investment allocation decisions are made, more information about major categories of plan assets, including concentrations of risk and fair value measurements and the fair value techniques and inputs used to measure plan assets. FSP No. 132(R) (ASC 715-20-65-2) is effective for annual periods ending after December 15, 2009. S&T does not anticipate that the adoption of FSP No. 132(R) (ASC 715-20-65-2) will have a significant impact on S&T’s consolidated results of operations or financial position.

NOTE D - ACQUISITION

On June 6, 2008, S&T completed the acquisition of 100 percent of the voting shares of IBT Bancorp, Inc. located in Irwin, Pennsylvania, (“IBT”) which was the sole shareholder of Irwin Bank, in a stock and cash transaction valued at approximately $176.6 million. Pursuant to the terms of the merger agreement, shareholders of IBT were entitled to elect to receive for each share of IBT common stock that they owned, either $31.00 in cash or 0.93 of a share of S&T common stock. S&T issued 2,751,749 shares of common stock out of its treasury shares at a recorded fair value of $91.7 million based on $33.33 per share which was the closing price on May 12, 2008, the day before the IBT shareholders approved the merger and paid a total of $75.1 million in cash to the former IBT shareholders. The acquisition significantly expands S&T’s market share in the growing Allegheny and Westmoreland County markets in Western Pennsylvania. The acquisition was accounted for under the purchase method, and all transactions of IBT since the acquisition date are included in S&T’s consolidated financial statements.

NOTE E -FAIR VALUE MEASUREMENT AND FAIR VALUE OF FINANCIAL INSTRUMENTS

Effective January 1, 2008, S&T adopted SFAS No. 157 (ASC 820-10), “Fair Value Measurements.” SFAS No. 157 (ASC 820-10) provides enhanced guidance for using fair value to measure assets and liabilities. SFAS No. 157 (ASC 820-10) also responds to investors’ requests for expanded information about the extent to which a company measures assets and liabilities at fair value, the information used to measure fair value, and the effect of fair value measurements on earnings. SFAS No. 157 (ASC 820-10) applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. SFAS No. 157 (ASC 820-10) does not expand the use of fair value in any new circumstances. FSP FAS No. 157-2 (ASC 820-10) delayed the effective date of SFAS No. 157 (ASC 820-10) for nonfinancial assets and liabilities that are not remeasured at fair value on a recurring basis until fiscal years beginning after November 15, 2008 and interim periods within those years. For companies with calendar year ends that have not previously applied the provisions of SFAS No. 157 (ASC 820-10) to nonrecurring fair value measurements of nonfinancial items based on the deferral in FSP FAS No. 157-2 (ASC 820-10), the application of SFAS No. 157 (ASC 820-10) to those measurements was required beginning in the first quarter of 2009.

Fair-Value Hierarchy

SFAS No. 157 (ASC 820-10) specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable.

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – continued

Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect S&T’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1 - Quoted prices for identical instruments in active markets.

Level 2 - Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets.

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

SFAS No. 157 (ASC 820-10) requires the use of observable market data when available.

Determination of Fair Value

S&T measures fair value using the procedures set out below for all assets and liabilities measured at fair value.

When available, S&T generally uses quoted market prices to determine fair value, and classifies such items in Level 1. In some cases where a market price is available, S&T will make use of acceptable practical expedients (such as matrix pricing) to calculate fair value, in which case the items are classified in Level 2.

If quoted market prices are not available, fair value is based upon internal valuation techniques that use, where possible, current market-based or independently sourced market parameters, such as interest rates. Items valued using such valuation techniques are classified according to the lowest level input or value driver that is significant to the valuation. Thus, an item may be classified in Level 3 even though there may be some significant inputs that are readily observable.

The following section describes the valuation methodologies used by S&T to measure different financial instruments at fair value, including an indication of the level in the fair value hierarchy in which each instrument is generally classified. Where appropriate, the description includes details of the valuation models, the key inputs to those models, as well as any significant assumptions.

Investments

The investments category includes available for sale debt and equity securities, whose fair value is determined using the following methodology:

Debt Securities – S&T obtains fair values for debt securities from a third-party pricing service which utilizes several sources for valuing fixed-income securities. The majority of the market evaluation sources includes observable inputs rather than “significant unobservable inputs” and therefore falls into the Level 2 category.

S&T’s U.S. government agencies and mortgage backed securities portfolio are valued based on market data. The service provider utilizes evaluated pricing models that vary based 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 and are classified as Level 2.

S&T’s obligations of state and political subdivisions portfolio is valued using proprietary valuation matrices from the service provider, which incorporates the recent unprecedented changes in the municipal market. 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 and are classified as Level 2.

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

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – continued

Trading Assets

When available, S&T uses quoted market prices to determine the fair value of trading assets; such items are classified in Level 1 of the fair-value hierarchy. Since S&T’s only trading account asset is a Rabbi Trust for deferred compensation plans, which is invested in two readily quoted mutual funds, the Rabbi Trust asset is classified as Level 1 and is recorded in other assets in S&T’s Condensed Consolidated Balance Sheet.

Mortgage Servicing Rights

The fair value of the MSRs are estimated by calculating the present value of estimated future net servicing cash flows, taking into consideration actual and expected mortgage loan prepayment rates, discount rates, servicing costs and other economic factors, which are determined based on current market conditions. The expected and actual rates of mortgage loan prepayments are the most significant factors driving the value of MSRs.

These MSRs, which totaled $1,668,000 as of September 30, 2009, are classified as part of other assets on S&T’s Condensed Consolidated Balance Sheet. Changes in the valuation allowance for MSRs are recorded in mortgage banking in S&T’s Condensed Consolidated Statement of Income. MSRs are classified as Level 3 because the valuation model includes significant unobservable inputs.

Derivative Financial Instruments

S&T has certain interest rate derivative positions that are not designated as hedging instruments. 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 the 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 to provide long-term fixed rate financing to the customer while retaining a variable rate asset on the balance sheet. Because S&T has two offsetting swaps, changes in the fair value of the underlying derivative contracts largely offset each other and do not materially impact S&T’s results of operations. These interest rate swaps are marked to market on a quarterly basis after considerations of counterparty and S&T credit risk and collateral. Because the estimated fair value includes certain observable inputs, it is considered a Level 2 fair value.

S&T also offers rate lock commitments to potential borrowers for residential mortgage loans. 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 risks if interest rates increase significantly before the loan can be closed and sold. S&T may utilize forward sales 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 by S&T for the benefit of the mortgagee, and in turn a forward sales contract is executed between S&T and the investor. Both the rate lock commitment and the corresponding forward sales contract for each customer are considered derivatives. The mortgagee typically has the option to not exercise the mortgage commitment; however, S&T is contractually obligated on both the commitment for the mortgage and the future sales contract. As such, changes in the fair value of the derivatives during the commitment period are recorded in current earnings and included in other income on the consolidated statements of income. These rate lock commitments and the corresponding forward sales contracts are marked to market on a quarterly basis. Because the estimated fair value includes certain observable inputs, it is considered a Level 2 fair value.

S&T periodically utilizes interest rate swap contracts for asset and liability management. These transactions involve both credit and market risk. The notional amounts are amounts on which calculations and payments are based. The notional amounts do not represent direct credit exposures. Direct credit exposure is limited to the net difference between the calculated amounts to be received and paid, if any. 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. As of September 30, 2009, S&T is not utilizing interest rate swap contracts for non-customer positions.

Loans Originated for Sale and 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. As a result, the carrying amount of loans held for sale has not been included in the disclosure of fair value hierarchy in the table above. 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 would be considered a Level 2 disclosure.

The following table presents the changes in the Level 3 fair-value category for the nine-month period ended September 30, 2009 and 2008. S&T classifies financial instruments in Level 3 of the fair-value hierarchy when there is reliance on at least one significant unobservable input to the valuation model. In addition to these unobservable inputs, the valuation models for Level 3 financial instruments typically also rely on a number of inputs that are readily observable either directly or indirectly. Thus, the gains and losses presented below include changes in the fair value related to both observable and unobservable inputs.

Items Measured at Fair Value on a Nonrecurring Basis

Impaired Loans

A loan is considered to be impaired when it is probable that all of the principal and interest due under the original terms of the loan may not be collected. S&T’s policy for impairment includes a review of commercial and industrial and commercial real estate loans greater than $500,000. Impairment is measured based on the fair value of the underlying collateral.

When the fair value is based on an observable market price or a current appraisal, impaired loans are classified as Level 2. When a current appraisal is not available, or if management determines the fair value of the collateral is further impaired below the appraised value and there is no observable market price, the impaired loans are classified as Level 3. Impaired loans are recorded in portfolio loans in S&T’s Condensed Consolidated Balance Sheets.

The following table presents S&T’s assets and liabilities that are measured at fair value on a nonrecurring basis by fair value hierarchy level at September 30, 2009 and December 31, 2008.

In addition to financial instruments recorded at fair value in S&T’s financial statements, SFAS No. 107 (ASC 825-10), disclosure about Fair Value of Financial Instruments, requires disclosure of estimated fair value of all of an entity’s assets and liabilities considered to be financial instruments. For S&T, as for most financial institutions, the majority of its assets and liabilities are considered to be financial instruments as defined in SFAS No. 107(ASC 825-10). 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 fair value disclosure purposes, S&T substantially utilized the fair value measurement criteria as required under SFAS No. 157 (ASC 820-10) and explained above. In cases where quoted fair values were not available, S&T uses present value methods to estimate the fair value of its financial instruments. These estimates of fair value are significantly affected by the assumptions made and, accordingly, do not necessarily indicate amounts that could be realized in a current market exchange.

For the financial instruments not required to be included in the SFAS No. 157 (ASC 820-10) above, the following methods and assumptions were used by S&T in estimating its fair value disclosures:

Cash and Cash Equivalents and Other Short-term Assets

The carrying amounts reported in the condensed consolidated balance sheets for cash and due from banks, interest-earning deposits with banks and federal funds sold approximate those assets fair values.

Loans

For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. The fair values for other loans are estimated using discounted cash flow analyses, using 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 fair value.

Deposits

The fair values disclosed for demand deposits (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, and certificates of deposit approximate their fair value at quarter-end. 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.

Short-term Borrowings and Other Borrowed Funds

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

Long-term Borrowings

The fair values disclosed for long-term borrowings are estimated using current interest rates for long-term borrowings of similar remaining maturities and adjusted for any related credit factors.

S&T BANCORP, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS – continued

Junior Subordinated Debt Securities

For the variable-rate junior subordinated debt securities that reprice quarterly, fair values are based on carrying values and adjusted for any related credit factors. For the fixed rate junior subordinated debt securities, the fair values disclosed are estimated using current rates for junior subordinated debt securities of similar remaining maturities and adjusted for any related credit factors.

Loan Commitments and Standby Letters of Credit

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 counter-parties. Also, unfunded loan commitments relate principally to variable-rate commercial loans and typically non-binding.

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. S&T believes it is impractical to estimate a representational fair value for these types of assets, which represent significant value to S&T.

The following table indicates the estimated fair value of S&T’s financial instruments as of :

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 customer to effectively convert a variable rate loan to a fixed rate. These agreements could have floors or caps.

Pursuant to S&T’s agreements with various derivative dealers, S&T may be required to post collateral based upon mark-to market positions. Beyond unsecured threshold levels, collateral in the form of securities may also be made available to counterparties of swap transactions from the available for sale investment portfolio when required. Based upon S&T’s current positions and related future collateral requirements relating to them, S&T believes that 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 bank or a customer, fails to meet its contractual obligations. All derivative contracts may be executed only with counterparties approved by S&T’s Asset and Liability Committee, and only within S&T’s Board of Directors Credit Committee approved credit exposure limits.

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 risks if interest rates increase significantly before the loan can be closed and sold. S&T may utilize forward sales 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 sales contract may be executed between S&T and the investor. Both the rate lock commitment and the corresponding forward sales contract for each customer are considered derivatives pursuant to SFAS No. 133 (ASC 815-10), “Accounting for Derivative Instruments and Hedging Activities” and do not qualify for hedge accounting. As such, changes in the fair value of the derivatives during the commitment period are recorded in current earnings and included in other income on the condensed consolidated statements of income.

For debt securities classified as available for sale, S&T does not believe any individual unrealized loss as of September 30, 2009 represents an other-than-temporary impairment. S&T performs a review of the entire securities portfolio on a quarterly basis to identify securities that may indicate an other-than-temporary impairment. S&T management considers the length of time and the extent to which the fair value has been less than cost and the financial condition of the issuer. The unrealized losses on seventeen debt securities at September 30, 2009 are attributable to changes in interest rates. The unrealized losses on thirteen marketable equity securities at September 30, 2009 are attributable to temporary declines in fair value. S&T does not intend to sell or it is not more likely than not that it 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.

There were $198,000 and $3,100,000 in gross realized gains and $4,799,000 and $4,600,000 in gross realized losses for the nine months ended September 30, 2009 and 2008, respectively, relative to securities available for sale. S&T recognized other-than-temporary impairments totaling $4,135,000 on eleven equity securities during the first nine months of 2009 and $3,900,000 of other-than temporary impairments on five equity securities during the first nine months ended September 30, 2008, which are included in the gross realized losses. For the three months ended September 30, 2009, S&T recognized other-than-temporary impairments of $2,066,000 on seven equity securities and recognized $2,600,000 of other-than-temporary impairments on two equity securities for the three months ended September 30, 2008.

The principal balances of loans on nonaccrual status were $86,454,000 and $42,466,000 at September 30, 2009 and December 31, 2008, respectively. Included in the principal balances of loans on nonaccrual status was one restructured loan totaling $1,435,000 at September 30, 2009. Assets acquired through foreclosure or repossession, which is included in other assets, was $4,745,000 at September 30, 2009 and $851,000 at December 31, 2008.

S&T attempts to limit its exposure to concentrations of credit risk by diversifying its loan portfolio. S&T monitors concentrations of credit risk. At September 30, 2009 and December 31, 2008, S&T had no concentrations of credit risk by industry or group. The commercial real estate portfolio comprises $1.8 billion or 52 percent of total loans at September 30, 2009. However, the segmentation (types of loans) within the commercial real estate portfolio have no concentration in excess of 10 percent of total loans. In addition, the commercial real estate portfolio had $353.6 million or 10 percent of total loans to customers outside of western Pennsylvania. Geographic concentrations exist because S&T provides a full range of banking services, including commercial, consumer and mortgage loans to individuals and corporate customers in its ten-county market areas in western Pennsylvania. Management believes underwriting guidelines and ongoing review by loan administration mitigate these risks.

Federal Home Loan Bank Advances		82,550		308,475

Total	$	143,980	$	421,894

Short-term borrowings are for terms under one year and were comprised of retail repurchase agreements (“REPOs”), wholesale REPOs, federal funds purchased and Federal Home Loan Bank (“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 REPOs financing arrangements cannot be sold or repledged by the secured party. The 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; overnight and FHLB advances are for various terms secured by a blanket lien on residential mortgages and other real estate secured loans with the FHLB of Pittsburgh.

Following is a summary of long-term debt at:


*(dollars in thousands)*	September 30, 2009		December 31, 2008

Junior subordinated debt		90,619		90,619

Total	$	186,772	$	270,950

The purpose of these long-term borrowings is to match-fund selected new loan originations, to mitigate interest-rate sensitivity risk to take advantage of discounted borrowing rates through the FHLB for community investment projects and as a source of regulatory capital as in the case of junior subordinated debt securities. S&T had long-term debt outstanding of $118,053,000 at September 30, 2009 at a fixed rate and $68,719,000 at a variable rate. Long-term borrowings at December 31, 2008 included repurchase agreement borrowings with embedded floors of $50,000,000 and the weighted average rate was 2.53 percent.

NOTE K - GUARANTEES

S&T, in the normal course of business, commits to extend credit and issue standby letters of credit. The obligations are not recorded in S&T’s financial statements. Loan commitments and standby letters of credit are subject to S&T’s normal credit underwriting policies and procedures and generally require collateral based upon management’s evaluation of each customer’s financial condition and ability to satisfy completely the terms of the agreement. S&T’s exposure to credit loss in the event the customer does not satisfy the terms of the agreement equals the notional amount of the obligation less the value of any collateral. Unfunded commercial loan commitments totaled $795,073,000, unfunded other loan commitments, comprised of credit card lines and home equity lines, totaled $244,343,000 and obligations under standby letters of credit totaled

The allowance for lending-related commitments is included in other liabilities.

NOTE L - LITIGATION

S&T, in the normal course of business, is subject to various legal proceedings in which claims for monetary damages are asserted. Management does not believe that the outcome of any current proceedings will have a material adverse effect on the consolidated financial position of S&T.

S&T completed a subsequent event review through the issue date of November 5, 2009 of this report. As part of that review, fair values of the securities portfolio were reviewed to evaluate if there were any material declines in fair value. There were no subsequent events determined or material declines in fair value of the securities portfolio since the balance sheet date of September 30, 2009 as concluded in the review.

Item 2.

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

The following discussion and analysis is presented so that shareholders may review in further detail the financial condition and results of operations of S&T Bancorp, Inc. and subsidiaries (“S&T”). This discussion and analysis should be read in conjunction with the condensed consolidated financial statements and the other financial data presented elsewhere in this report.

Business Summary

S&T is a financial holding company with its headquarters located in Indiana, Pennsylvania and with assets of approximately $4.2 billion at September 30, 2009. S&T provides a full range of financial services through a network of 55 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; financial and estate planning; estate and trust administration; investment management; employee benefit services and administration; corporate services and other fiduciary services. S&T’s common stock trades on the Nasdaq Global Select Market under the symbol “STBA”.

Recent turbulence in significant portions of the global financial and real estate markets has adversely impacted our performance, both directly by affecting our revenues and the value of our assets and liabilities, and indirectly by affecting the economy in general. During the first nine months of 2009, S&T’s performance was specifically negatively impacted by sharp increases in delinquencies and nonperforming loan levels and the overall slowdown in the economy that is affecting all segments of the loan portfolio. The area of commercial loans has been and continues to be the subject of considerable management focus and review.

During the first nine months of 2009, S&T temporarily reduced borrowings since participation in the U. S. Treasury Capital Purchase Program provided increased liquidity pending deployment into loans or debt securities purchases. The decrease in borrowings is also the result of decreased loan demand as consumers and businesses react to the economic slowdown, and maturing investment securities not being replaced as an S&T Asset Liability Committee (“ALCO”) strategy to limit the replacement of matured investment securities to mitigate interest rate and liquidity risk. As a result, total assets at September 30, 2009 decreased from total assets at December 31, 2008.

On June 6, 2008, S&T completed its acquisition of IBT, pursuant to an Agreement and Plan of Merger, by and between S&T and IBT, dated December 16, 2007 (the “Merger Agreement”). Pursuant to the terms of the Merger Agreement, which was approved by the shareholders of IBT on May 13, 2008, IBT was merged with and into S&T, with S&T being the surviving corporation (the “Merger”). In connection with the Merger, IBT shareholders received for each share of IBT common stock they held, at their election, either $31.00 in cash or 0.93 of a share of S&T common stock. IBT shareholders could elect to receive all cash, all S&T common stock, or a combination of cash and S&T common stock for their shares of IBT common

stock. Directors, officers and employees had their stock options cancelled for a cash payment equal to the difference between $31.00 and the exercise price per share for each such stock option, which IBT paid immediately prior to the merger. S&T issued a total of 2,751,749 shares of S&T common stock at a recorded fair value of $91.7 million and paid a total of $75.1 million in cash to the former IBT shareholders. The acquisition significantly expanded S&T’s market share in the growing Allegheny and Westmoreland County markets in western Pennsylvania. The acquisition was accounted for under the purchase method, and all transactions of IBT since the acquisition date are included in S&T’s consolidated financial statements.

On January 16, 2009, S&T completed a $108,676,000 capital raise as a participant in the U.S. Treasury Capital Purchase Program. In conjunction with S&T’s participation in the Program, S&T issued to the U.S. Treasury 108,676 shares of S&T’s Series A Preferred Stock, having a liquidation amount per share equal to $1,000 per share, for a total price of $108,676,000. The Series A Preferred Stock pays cumulative dividends at a rate of 5 percent per year for the first five years and thereafter at a rate of 9 percent per year. S&T calculated the fair value of the preferred stock using a discounted cash flow model and a 10% discount rate. The level yield method is used to amortize the discount on the preferred stock over a period of five years. Under changes made to the program 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 program investment, then it must pay a minimum of 25 percent of the issuance price, or $27,169,000. The Series A Preferred Stock is generally non-voting. Prior to January 16, 2012, unless 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, the consent of the U.S. Treasury will be required for S&T to increase its common stock dividend 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.

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.

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. Management engaged an outside expert to calculate the fair value of the common stock warrants issued by S&T on January 16, 2009. The methodology used for deriving fair value was estimated using the binomial pricing model and incorporated assumptions called for by Paragraph 16 and Appendix A of SFAS 123(R) (ASC 718-10). When reviewing the assumptions, the guidance in SEC Staff Accounting Bulletin No. 107 was utilized.

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


Assumption	Value
Contractual Term		10 Years
Exercise Price	$	31.53
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. S&T calculated the fair value of the preferred stock using a discounted cash flow model and a 10 percent discount rate. The level yield method is used to amortize the discount on the preferred stock over a period of five years. The Warrant expires ten years from the issuance date. If, on or prior to December 31, 2009, S&T receives aggregate gross cash proceeds of not less than $108,676,000 from qualified equity offerings announced after October 13, 2008, the number of shares of common stock issuable pursuant to the U.S. Treasury’s exercise of the Warrant will be reduced by one-half of the original number of shares. 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.

Recent Government Regulation

On October 3, 2008, the Emergency Economic Stabilization Act of 2008 (the “EES Act”) was signed into law. Among other things, the EES Act allocated up to $700 billion towards purchasing and insuring troubled assets held by financial institutions for the purpose of stabilizing and providing liquidity to the U.S. financial markets. The EES Act established the basic framework and policy goals, and vested the U. S. Treasury with the authority to carry out the EES Act’s purpose.

On October 14, 2008, pursuant to authority granted under the EES Act, the U.S. Treasury announced the Program whereby the U.S. Treasury agreed to purchase senior preferred shares from qualifying U.S. financial institutions. Each participating institution may sell an amount of senior preferred shares ranging from 1.0 percent to 3.0 percent of its September 30, 2008 risk-weighted assets. The preferred shares are generally nonvoting, pay an initial dividend rate of 5.0 percent per year for the first five years increasing to 9.0 percent per year after year five. Under changes made to the program by the 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 program investment, then it must pay a minimum of 25 percent of the issuance price, or $27,169,000. As part of the consideration for the shares, the U.S. Treasury requires the receipt of Warrants to acquire common stock from the participating institution having an aggregate market price equal to 15.0 percent of the amount of capital invested by the U.S. Treasury in the senior preferred shares, at an exercise price equal to the average trailing 20-trading day market price of the institution’s common stock at the time of issuance. Participating institutions must agree to certain limitations on executive compensation, repurchases of junior preferred or common stock and increases in common stock dividend payments. S&T applied to participate in the Program and was approved to receive $108,676,000 in exchange for the U.S. Treasury purchase of S&T senior preferred stock. The transaction closed on January 16, 2009.

On February 17, 2009, the American Recovery and Reinvestment Act of 2009 (“ARRA”) was signed into law. Among other things, the ARRA includes new executive compensation and corporate governance restrictions that apply not only prospectively, but also retroactively, to institutions, such as S&T that have received funds under the Program. The ARRA also provides a provision that permits early redemption of Series A Preferred Stock issued in the Program without increasing common equity, subject to approval of banking regulatory agencies. S&T is currently evaluating the effect that the ARRA executive compensation provisions will have on S&T.

On February 18, 2009, the Homeowner Affordability and Stability Plan (“HASP”) was announced by the President of the United States. HASP is intended to support a recovery in the housing market and ensure that eligible homeowners can continue to pay their mortgages. HASP includes the following initiatives: (i) a refinance option for homeowners that are current in their mortgage payments and whose mortgages are owned by Fannie Mae or Freddie Mac; (ii) a $75 billion homeowner stability initiative to prevent foreclosures and help eligible borrowers stay in their homes by offering loan modifications that reduce mortgage payments to more affordable and sustainable levels; and (iii) a support for low mortgage rates by increasing the U.S. Treasury’s funding commitment to Fannie Mae and Freddie Mac. Among other things, HASP would offer monetary incentives to mortgage servicers and mortgage holders for certain modifications of at-risk loans, and would establish an insurance fund designed to reduce foreclosures. Participation by S&T in HASP is currently voluntary. S&T continues to monitor these developments and assess their potential impact on its business.

Financial Condition

Total assets averaged $4.3 billion in the first nine months of 2009 and $4.0 billion for the 2008 full year average. Average loans increased $262.8 million and average securities, other investments and federal funds sold decreased $6.8 million in the first nine months of 2009 as compared to the 2008 full year average. Average deposits increased $343.9 million and average borrowings decreased $177.5 million during the nine months ended September 30, 2009 as compared to the 2008 full year average. As a result of the IBT acquisition in June of 2008, average assets increased $452.3 million, average securities increased $147.3 million, average loans increased $278.5 million and average deposits increased $326.0 million.

The yield on earning assets and the net interest margin are presented on a fully tax-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 non-GAAP measure to be the preferred industry measurement of net interest income and provides relevant comparison between taxable and non-taxable amounts. This non-GAAP measure and is further discussed on page 34.

Lending Activity

Average loans increased $262.8 million to $3.5 billion during the nine months ended September 30, 2009 as compared to the 2008 full year average. Changes in the composition of the average loan portfolio included increases of $96.2 million of residential mortgages and home equity loans, $229.9 million of commercial real estate loans, $2.5 million of consumer loans, offset by a decrease of $65.8 million in commercial and industrial loans. As a result of the IBT acquisition in June of 2008, average loans increased $278.5 million. The composition of the IBT loan portfolio included $26.7 million of commercial and industrial loans, $119.2 million of residential mortgages and home equity loans, $125.8 million of commercial real estate loans and $6.8 million of consumer loans. Average organic loans decreased $15.6 million. The composition of the average organic loan decreases included $92.5 million of commercial and industrial loans, $23.0 million of residential mortgages and home equity loans, $4.3 million of consumer loans, offset by an increase of $104.2 million in commercial real estate loans.

Average commercial loans, including commercial real estate, commercial and industrial and real estate construction comprised 73 percent of the average loan portfolio for the nine months ended September 30, 2009 and 74 percent for the 2008 full year average. 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 portfolio had $353.6 million or 10 percent of total loans that involved projects outside of western 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 as compared to western Pennsylvania. Accordingly, the out of state portfolio is experiencing higher credit stress and has been the subject of considerable management focus and review. Rates and terms for commercial real estate, equipment loans and lines of credit are normally negotiated, subject to such variables as the financial condition of the borrower, economic conditions, marketability of collateral, credit history of the borrower and projected future cash flows. The loan to value policy

S&T BANCORP, INC. AND SUBSIDIARIES

Item 2.

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

guideline for commercial real estate loans is generally 65-85 percent. Variable-rate commercial loans were 49 percent of the commercial loan portfolio at September 30, 2009 and 49 percent at December 31, 2008.

Average residential mortgage loans comprised 25 percent of the average loan portfolio for the nine months ended September 30, 2009 and 23 percent for the 2008 full year average. Residential mortgage lending reached record levels during the first nine months of 2009 as consumers took advantage of lower interest rates. Residential mortgage lending continues to be a strategic focus in 2009 through our 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 30 percent of residential mortgages and are sometimes 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 fair value of the mortgage property. At September 30, 2009, 10 percent of the residential mortgage portfolio consisted of adjustable rate mortgages with repricing terms of one, three and five years compared to 9 percent at December 31, 2008.

S&T periodically 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 long-term residential mortgages in the loan portfolio, generate fee revenue from servicing, and maintain the primary customer relationship. During the nine months ended September 30, 2009 and 2008, S&T sold $116.7 million and $14.4 million, respectively, of 1-4 family mortgages and services $247.3 million of secondary market mortgage loans sold to Fannie Mae. During the first nine months of 2009, S&T experienced record levels of mortgage banking activities, including but not limited to refinancing, as consumers took advantage of low interest rates. This increase in mortgage banking activities resulted in significantly higher sales of 1-4 family mortgages to Fannie Mae in the first nine months of 2009 as compared to the same period of 2008. S&T intends to continue to sell longer-term loans to Fannie Mae in the future on a selective basis, especially during periods of lower interest rates.

Average consumer loans comprised 2 percent of the loan portfolio for the nine months ended September 30, 2009 and 3 percent for the 2008 full year average. The average balance of consumer loans for the nine months ended September 30, 2009 was $82.0 million as compared to $79.5 million for the 2008 full year average. S&T offers a variety of unsecured and secured consumer loan and credit card products.

Management intends to continue to pursue quality loans in a variety of lending categories in order to enhance shareholder value. S&T’s loan portfolio primarily represents loans to businesses and consumers in our market area of western Pennsylvania. Management continues to develop and improve the effectiveness of our credit and loan administration processes and staff, which assists management in evaluating loans before they are made and in identifying problem loans early.

Securities Activity

Average securities, other investments and federal funds sold decreased by $6.8 million in the first nine months of 2009 compared to the 2008 full year average. As a result of the IBT acquisition in June of 2008, Average securities increased $147.3 million, offset by an average decrease of $154.1 million in securities, which is attributable to an ALCO strategy to limit the replacement of matured investment securities with borrowings to mitigate interest rate risk.

The components of the decrease of $6.8 million are decreases of $20.5 million in U.S. government corporations and agencies, $15.9 million in marketable equity securities and $1.7 million in other securities. Offsetting these decreases are increases of $25.0 million in mortgage-backed securities, $3.4 million in obligations of state and political subdivisions and $2.8 million in other investments. The increase of $2.8 million in other investments in the first nine months of 2009 compared to the 2008 full year average are comprised of FHLB stock that is a membership and borrowing requirement and is recorded at historical cost. The amount of S&T’s investment in FHLB stock, which is $23.5 million as of September 30, 2009, depends upon S&T’s borrowing availability and level from the FHLB. Average federal funds sold increased $0.2 million in the first nine months of 2009 compared to the 2008 full year average. At September 30, 2009, the equity securities portfolio had total fair value of $12.9 million compared to $14.9 million at December 31, 2008 and net unrealized losses of $0.2 million at September 30, 2009

S&T BANCORP, INC. AND SUBSIDIARIES

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

compared to net unrealized losses of $3.6 million at December 31, 2008. The equity securities portfolio consists of securities traded on the various stock markets and is subject to changes in fair value.

S&T’s policy for security classification includes U.S. treasury securities, U.S. government corporations and agencies, mortgage-backed securities of U.S. government corporations and agencies, collateralized mortgage obligations, states and political subdivisions, corporate securities, marketable equity securities and other securities as available for sale. On a quarterly basis, management evaluates the securities portfolios for other-than-temporary declines in fair value in accordance with FSP FAS No. 115-1 and No. 124-1 (ASC 320-10), “The Meaning of Other-Than-Temporary Impairment and its Application to Certain Investments” as well as FSP FAS No. 115-2 and No. 124-2 (ASC 320-10), “Recognition and Presentation of Other-Than-Temporary Impairments.” During the first nine months of 2009, there was $4.1 million of realized losses taken for other-than-temporary impairment on 11 bank equity investment securities. The performance of the equities and debt securities markets could generate further impairment in future periods. At September 30, 2009, net unrealized gains on securities classified as available for sale, including equity securities, were $10.3 million as compared to net unrealized gains of $3.3 million at December 31, 2008. Net unrealized gains related to S&T’s debt securities portfolio totaled $10.5 million at September 30, 2009 and $6.9 million unrealized gains at December 31, 2008. S&T does not intend to sell or it is not more likely than not that it will be required to sell any of the securities in an unrealized loss position before recovery of its amortized cost.

S&T was notified in December of 2008 by the FHLB that they have suspended the payment of dividends and the repurchase of excess capital stock until further notice. FHLB stock does not have a readily determinable fair value for purposes of SFAS No. 115 (ASC 320-10), “Accounting for Certain Investments in Debt and Equity Securities.” FHLB stock is viewed as a long-tem investment which is carried at cost. S&T management reviewed and evaluated the FHLB capital stock for other-than-temporary impairment at September 30, 2009 which is determined based on the ultimate recoverability of the par value rather than by temporary declines in value or dividend fluctuations. Management considered the suspension of dividends and the repurchase of excess capital stock by the FHLB Board of Directors in a letter to member banks dated December 23, 2008. Management reviewed the FHLB’s Form 10-Q for the period ended June 30, 2009 filed with the Commission on August 12, 2009.

Management considered the following matters in accordance with SOP 01-06 (ASC 942-10), “Disclosures Concerning Credit Losses Related to Loans” :

•

Significance and severity of the decline in the net assets of the FHLB (including its investment portfolio) as compared to the capital stock amount of the FHLB and the length of time this situation has persisted.

•

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. 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, there are no pending legislative or regulatory changes that would impact the customer base of the FHLB’s.

•

Liquidity position of the FHLB.

Management considered the following items from the June 30, 2009 Form 10-Q of the FHLB:

•

The total capital of the FHLB decreased to $3.5 billion at June 30, 2009 from $4.1 billion at December 31, 2008.

•

The net income of the FHLB for the six months ended June 30, 2009 decreased to $8.5 million from $110.5 million in the comparable period in 2008.

•

The FHLB exceeded all required capital ratios as of June 30, 2009 and December 31, 2008. In addition, permanent capital of $4.5 billion and $4.2 billion at June 30, 2009 and December 31, 2008, respectively exceeded its risk based capital requirement by $876.1 million and $233.8 million, respectively.

S&T BANCORP, INC. AND SUBSIDIARIES

Item 2.

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

•

The gross unrealized losses on its private label mortgage backed securities (“MBS”) decreased to $1.1 billion at June 30, 2009 from $2.1 billion at December 31, 2008. However, management also noted the following:

•

The FHLB concluded that these unrealized losses were not other-than-temporary as of June 30, 2009.

•

The FHLB MD&A disclosed that all MBS continue to pay principal and interest in accordance with their contractual terms.

•

44 percent of these securities were rated AAA by external credit agencies.

•

The FHLB had minimal subprime exposure in its private label MBS portfolio.

•

The liquidity position of the FHLB (defined as cash and due from banks, interest-earning deposits and federal funds sold) increased to $9.2 billion at June 30, 2009 as compared to $6.4 billion at December 31, 2008.

Based on this review, management concluded that sufficient evidence did not exist to conclude that its investment in FHLB stock was other-than-temporarily impaired as of September 30, 2009. Because the investment in FHLB stock is viewed as a long-term investment, the temporary suspension of dividends and repurchase of excess capital stock was considered in light of the FHLB’s overall financial position as discussed above and was not deemed to present an other-than-temporary impairment.

Allowance for Loan Losses

The balance in the allowance for loan losses was $60.9 million or 1.77 percent of total loans at September 30, 2009 as compared to $42.7 million or 1.20 percent of total loans at December 31, 2008. The increase in the allowance for loan losses is primarily a result of an increase of $10.8 million in specific reserves and an increase of $7.4 million in general reserves during the first nine months of 2009. S&T’s allowance for lending-related commitments such as unfunded commercial real estate, commercial and industrial term loan commitments and letters of credit totaled $4.7 million at September 30, 2009 and $1.3 million at December 31, 2008. The allowance for lending-related commitments is included in other liabilities.

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 Loan Administration Department and various management and director committees. Updates are presented to the S&T Board of Directors (“Board”) as to the status of loan quality and the Board approves the adequacy of the allowance for loan losses. 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 portfolios economic life cycle. The analysis 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, due to the continuing growth, 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.

During the first nine months of 2009, the risk rating profile of the portfolio was significantly impacted by the following commercial loan relationships:

•

The first relationship consists of $30.3 million of commercial and industrial loans with an exploration and drilling company comprised of five different facilities and three legal entities. Decreases in commodity prices have created cash flow difficulties for this company and a $9.3 million specific reserve had been established for the loans in the first quarter of 2009. Continued decreases in energy commodity prices created going concern issues for the company and a collateral liquidation strategy is in process. A charge-off of $26.5 million was taken on this relationship in the

S&T BANCORP, INC. AND SUBSIDIARIES

Item 2.

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

second quarter of 2009. This relationship was originated in September of 2002 and was placed into nonaccrual status in February of 2009. The underlying collateral for this relationship are assignments of partnership interests in energy production companies, assignments of brokerage accounts, personal residences and an aircraft. The brokerage accounts were liquidated in the second quarter of 2009 and the proceeds of $2.0 million were applied to loan balances. The balance of $0.6 million on the aircraft was transferred to other assets in the second quarter of 2009. The aircraft was sold in the third quarter of 2009 for $1.1 million and the proceeds were applied to satisfy the balance of the other asset owned and reduce other remaining loan balances. The last estimate of value was completed in June of 2009.

•

The second relationship has an aggregate balance of $16.9 million and is comprised of three projects in the New York and Connecticut regions. The first project is a $7.5 million real estate development participation loan that has delayed construction pending better economic conditions, for which a $2.0 million specific reserve has been established. The relationship was originated in January of 2006 and was placed into nonaccrual status in January of 2009. The underlying collateral for this relationship is a mortgage on an undeveloped parcel of real estate. The last appraisal was completed in March of 2009. The second project is $8.6 million for new condominiums construction. A specific reserve of $2.1 million that had previously been established for this project was increased to $4.2 million during the second quarter of 2009 based on the current appraisal. The last appraisal was completed in June of 2009. The underlying collateral for this relationship is the commercial real estate. The third project is a $0.8 million residual balance for a mixed-use commercial property previously charged down by $2.7 million in the first quarter of 2009. The last appraisal was completed in June of 2009. The underlying collateral for this relationship is the real estate.

•

The third relationship is a $2.5 million commercial and industrial loan secured by assignment of partnership interests. Unresolved legal issues among the partners make the valuation of the assigned partnership interests very difficult to ascertain. During the second quarter of 2009, management negotiated additional collateral that may mitigate future potential losses. As a result, specific reserves of $2.5 million previously established have been reduced to $2.1 million during the second quarter of 2009. The relationship originated in October of 2006 and was placed into nonaccrual status in March of 2009.

•

The fourth relationship has an aggregate balance of $2.1 million and is comprised of real estate loans on three distinct projects, the largest of which is a $1.3 million condominium project that has experienced slow absorption due to a downturn in the housing market. Specific reserves of $0.5 million have been established for the loans. The relationship originated in February of 2005 and was placed into nonaccrual status in February of 2009. The primary collateral consists of a completed condominium development project. The last appraisal was completed in February 2009. During 2009, six condominium units have been sold and 4 units are remaining to be sold.

•

The fifth relationship is a $3.7 million condominium project that has experienced slow absorption due to the downturn in the housing market. A specific reserve of $0.2 million was established based on appraisal value. The relationship originated in October of 2003 and was placed into nonaccrual status in January of 2009. The last appraisal was completed in March of 2009. The underlying collateral for this relationship is the condominium development and the unimproved land. During the third quarter of 2009, the relationship was transferred to other real estate owned resulting in a charge of $0.6 million to adjust the balance to the appraisal value less costs to sell of $2.7 million.

•

The sixth relationship is a $7.5 million commercial real estate project consisting primarily of a retail project in the western Pennsylvania region that did not fully stabilize or develop. Specific reserves of $0.6 million have been established for the loans. The relationship originated in March of 1999 and was placed into nonaccrual status in September of 2008. The last appraisal was completed in June of 2009. The primary collateral for this relationship is the commercial real estate.

•

The seventh relationship consists of several lot development projects in Pennsylvania and Florida. The exposure in Florida originally consisted of five projects totaling $12.5 million. Local real estate conditions in Florida resulted in slow lot sales and ultimately the developer’s global cash flow was unable to absorb the carrying costs associated with the Florida loans. In the second quarter of 2009, the Florida loans were split into an $8.8 million nonperforming tranche (3 loans) and a $3.7 million performing tranche (2 loans). S&T recognized a $5.3 million charge on the nonperforming loans during the second quarter of 2009 and developed a strategy to liquidate the nonperforming loans and complete the development associated with the performing loans. During the third quarter of 2009, it became evident that global cash flows were insufficient to execute on the original restructure plan. Accordingly, S&T

S&T BANCORP, INC. AND SUBSIDIARIES

Item 2.

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

recognized an additional charge of $2.9 million and liquidated a $0.6 million cash collateral account. The resulting Florida exposure is $3.7 million, $3.3 of which is nonperforming as of September 30, 2009. The relationship originated in March of 2004 and was placed into nonaccrual status in May of 2009. The last appraisal was completed in March of 2009. The underlying collateral for this relationship is undeveloped and developed single family lots.

The eighth relationship is a $1.8 million regional restaurant that entered into bankruptcy and subsequently closed. A $1.1 million charge was taken in the second quarter of 2009. The loan originated in September of 2005 and was placed into nonaccrual status in January of 2008. The underlying collateral for this relationship is a leasehold mortgage on the building. The remaining balance $0.7 million is in repossessed assets owned as of September 30, 2009.

•

The ninth relationship is an $11.5 million mixed-use redevelopment project in Pennsylvania which was placed into nonperforming status during the third quarter of 2009. The project is complete but is not stabilized. The loan originated in August of 2007. The underlying collateral for this relationship includes real estate, a United States Department of Agriculture guaranty, a letter of credit from another financial institution and personal guarantees of the developer. A specific reserve of $1.5 million has been established for this relationship. The last appraisal was completed in May of 2008 and updated appraisals have been ordered. In addition, S&T terminated certain interest rate derivatives resulting in counterparty fees of $1.4 million. This claim was recorded as a receivable and a decrease in noninterest income of $0.6 million was recognized on the under secured portions of this receivable.

Specific reserves increased $10.8 million and are primarily the result of the commercial loans discussed above as well as expanding the scope of loans subject to analysis. Management believes these commercial loans have been adequately reserved as determined by the quarterly impairment analysis and risk-rating process performed by the Loan Administration Department.

S&T has a charge-off policy within its general lending policy. The charge-off policy is broken down into two components – retail and commercial.

The charge-off policy for retail loans is broken down into two types. 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 ledger 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

•

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

Net loan charge-offs totaled $43.8 million or 1.67 percent of average loans on an annualized basis for the first nine months of 2009 as compared to $3.8 million or 0.16 percent of average loans on an annualized basis in the first nine months of 2008.

Net loan charge-offs during the first nine months of 2009 were primarily impacted by a $26.5 million charge-off for the aforementioned $30.3 million commercial relationship with an energy exploration and drilling company which had a specific reserve of $9.3 million, $8.2 million for three Florida lot development projects with a remaining exposure in Florida of $3.7

million, $2.7 million for a $3.5 million loan on a mixed use commercial property that lost a major tenant, $1.1 million for a $2.4 million office building that was foreclosed and sold during the first quarter of 2009, $1.1 million for a regional restaurant that entered into bankruptcy, $0.6 million for a multi-family development project in western Pennsylvania and $0.6 million for a retail sales company which discontinued operations.

Nonperforming loans, which included loans past due 90 days or more, at September 30, 2009 was $86.5 million or 2.51 percent of total loans. This compares to nonperforming loans of $42.5 million or 1.19 percent of total loans at December 31, 2008. Nonperforming assets totaled $91.2 million or 2.17 percent of total assets at September 30, 2009 and $43.3 million or 0.98 percent of total assets at December 31, 2008. There are no loans 90 days past due and still accruing interest. The provision for loan losses was $62.0 million for the first nine months of 2009, as compared to $7.3 million for the same period of 2008. The increased provision was the result of management’s detailed analysis of the adequacy of the allowance for loan losses and is consistent with the increase in classified and nonperforming loans, loan charge-off levels, the unfavorable credit experience with out of market loans, the effects of more conservative economic factors used in the allowance for loan losses model to be reflective of a deteriorating economy and the level of specific reserves established for impaired commercial loan relationships.

Deposits

Average total deposits increased by $343.9 million, or 12 percent, during the nine months ended September 30, 2009 as compared to the 2008 full year average. Changes in the average deposit mix include increases of $274.0 million in certificates of deposit, $89.3 million in demand deposits, $39.9 million in money market accounts and $43.6 million in NOW accounts. Offsetting these increases is a decrease of $102.9 million in savings accounts. As a result of the IBT acquisition in June of 2008, average deposits increased $326.0 million. The composition of these IBT deposits included $159.4 million in certificates of deposit, $79.2 million in demand and NOW accounts, $46.2 million of money market accounts and $41.2 million of savings accounts. Average organic deposit growth, or average deposit increases not associated with the IBT acquisition was $17.9 million. During the nine month period the average organic increase in certificates of deposits of $114.5 million is primarily attributable to an increase in brokered certificates of deposit. Demand deposits had an average organic increase of $34.1 million and money market and NOW accounts had an organic increase of $13.4 million. The average organic decrease of $144.1 million in savings accounts, is primarily attributable to S&T being less aggressive with external competitive pricing strategies. Other important strategies include providing cash management services to commercial customers to increase transaction related deposits, and enhanced delivery services such as electronic banking. Core deposit growth is an important strategic initiative for S&T, through the expansion of retail facilities, promotions and new products.

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 14 percent and 12 percent of total deposits at September 30, 2009 and at December 31, 2008, and primarily represent deposit relationships with local customers in our market area. S&T had $195.7 million and $59.0 million of brokered retail certificates of deposit outstanding at September 30, 2009 and December 31, 2008, respectively.

During the first quarter of 2009, S&T began participation 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 September 30, 2009, S&T had $100.0 million of brokered CDARS certificates of deposit and $32.5 million of the reciprocal CDARS. Both programs are classified as part of brokered retail certificates of deposit. The issuance of brokered retail certificates of deposits and participation in the CDARS program is an ALCO strategy to increase and diversify funding sources.

Borrowings

Average borrowings decreased $177.5 million for the first nine months of 2009 as compared to full year 2008 average. During the first nine months of 2009, S&T temporarily reduced borrowings since participation in the U. S. Treasury Capital Purchase Program provided increased liquidity pending deployment into loans or debt securities purchases. The decrease in borrowings is also the result of decreased loan demand as consumers and businesses react to the economic slowdown, and maturing investment securities not being replaced due to an ALCO strategy to limit the replacement of matured investment securities to

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

mitigate interest rate risk. Borrowings are comprised of retail repurchase agreements (“REPOs”), wholesale REPOs, federal funds purchased, FHLB advances and long-term borrowings. S&T defines REPOs with our local retail customers as retail REPOs; wholesale REPOs are those transacted with other banks and brokerage firms with terms normally ranging from one to 365 days.

The largest decrease in average borrowings for the first nine months of 2009 is a $112.9 million decrease in FHLB advances compared to the 2008 full year average. The decrease in FHLB advances was a strategic initiative in order to develop a better diversified mix of wholesale funding sources. The average balance in retail REPOs decreased approximately $27.1 million for the first nine months of 2009 compared to the 2008 full year average. S&T views REPOs as a relatively stable source of funds because most of these accounts are with local long-term customers.

Average long-term borrowings have decreased by $37.5 million in the first nine months of 2009 as compared to the full year 2008 average. At September 30, 2009, S&T had long-term borrowings outstanding of $118.1 million at a fixed rate and $68.7 million at a variable rate.

Capital Resources

Shareholders’ equity increased $93.0 million at September 30, 2009 as compared to December 31, 2008. The increase is primarily due to a $108.7 million capital raise as a participant in the U. S. Treasury Program. S&T had a net loss available to common shareholders of $5.6 million and dividends declared to common shareholders were $16.9 million for the nine months ended September 30, 2009. Also affecting capital was an increase of $0.7 million in the funded status of pension and $4.5 million in unrealized gains on securities available for sale, net of tax, which is included in other comprehensive income.

S&T continues to maintain a strong capital position with a leverage ratio of 9.9 percent at September 30, 2009 and 7.3 percent at December 31, 2008 as compared to the well capitalized regulatory guideline of 5.0 percent. S&T’s risk-based capital Tier I and Total ratios were 11.6 percent and 14.9 percent at September 30, 2009 and 8.7 percent and 11.8 percent at December 31, 2008. These ratios place S&T above the Federal Reserve Board’s well capitalized risk-based capital guidelines of 8.0 percent and 10.0 percent for Tier I and Total, respectively.

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 $300.0 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 September 30, 2009, S&T had not issued any securities pursuant to the shelf registration statement.

On January 16, 2009, S&T completed a $108,676,000 capital raise as a participant in the U.S. Treasury Capital Purchase Program (the “Program”). In conjunction with S&T’s participation in the Program, S&T issued to the U.S. Treasury 108,676 shares of S&T’s Series A Preferred Stock, having a liquidation amount per share equal to $1,000 per share, for a total price of $108,676,000. The Series A Preferred Stock pays cumulative dividends at a rate of 5 percent per year for the first five years and thereafter at a rate of 9 percent per year. Under changes made to the program by the 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 program investment, then it must pay a minimum of 25 percent of the issuance price, or $27,169,000. The Series A Preferred Stock is generally non-voting. Prior to January 16, 2012, unless 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, the consent of the U.S. Treasury will be required for S&T to increase its common stock dividend 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. 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.

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 the 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. The Warrant expires ten years from the issuance date. If, on or prior to December 31, 2009, S&T receives aggregate gross cash proceeds of not less than

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

$108,676,000 from qualified equity offerings announced after October 13, 2008, the number of shares of common stock issuable pursuant to the U.S. Treasury’s exercise of the Warrant will be reduced by one-half of the original number of shares. If S&T redeems the Series A Preferred Stock, S&T may also repurchase the warrant. 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 temporarily 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 of Pittsburgh which had the effect of increasing S&T’s liquidity for lending activities. S&T plans to deploy the funds through the purchase of U.S. government agency bonds and agency-guaranteed mortgage backed securities when market opportunities are presented. These securities can then be used as collateral for repurchase transactions, through which S&T will be able to obtain liquidity to fund new loan originations. This method of managing the funds ensures the availability of funds for lending to creditworthy borrowers while generating earnings for S&T.

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 tax-equivalent basis, operating revenue and the efficiency ratio. 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 tax-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 tax-equivalent basis on page 35 and 40.

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.

The efficiency ratio is recurring noninterest expense divided by recurring noninterest income plus net interest income, on a fully taxable equivalent basis, which ensures comparability of net interest income arising from both taxable and tax-exempt sources and is consistent with industry practice.

RESULTS OF OPERATIONS

Nine months ended September 30, 2009 compared to Nine months ended September 30, 2008

Net Income

S&T had a net loss of $5.6 million or a negative $0.20 diluted earnings per share for the nine months ended September 30, 2009 as compared to net income of $44.4 million or a positive $1.71 diluted earnings per share for the same period of 2008. The net loss during the nine months ended September 30, 2009 was primarily the result of higher provision for loan losses which was necessitated by the significant increase in loan charge-offs and the general deterioration of the credit quality in the loan portfolio, increased Federal Deposit Insurance Corporation (“FDIC”) premiums and surcharges and other-than-temporary impairments for equity investments compared to the same period of 2008. The common return on average assets was a negative 0.17 percent for the nine months ended September 30, 2009, as compared to a positive 1.55 percent for the nine months ended September 30, 2008. The common return on average equity was a negative 1.38 percent for the nine months ended September 30, 2009 compared to a positive 15.19 percent for the same period of 2008.

Net Interest Income

Net interest income on a fully taxable equivalent basis was $113.5 million, a $6.4 million or 6 percent increase for the nine months ended September 30, 2009 as compared to $107.1 million for the same period of 2008. The increase in net interest income in the first nine months of 2009 as compared to the same period of 2008 was primarily the result of a $384.1 million

S&T BANCORP, INC. AND SUBSIDIARIES

Item 2.

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

increase in average interest-earning assets, primarily driven by $425.8 million average interest-earning assets acquired through the IBT acquisition in the second quarter of 2008. The net interest margin on a fully taxable equivalent basis was 3.87 percent in the nine months ended September 30, 2009 as compared to 4.05 percent in the same period of 2008. The net interest margin was negatively affected in the first nine months of 2009 by higher delinquent interest and the inability to reduce core deposit rates by the same dramatic level of reduction in other short-term rates.

S&T’s one-year repricing gap position at September 30, 2009 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.

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. The rate shock incorporates management assumptions regarding the level of interest rate changes on non-maturity deposit products (savings, money market and NOW and demand deposits) 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.

For the nine months ended September 30, 2009, average loans increased $370.4 million, and average securities and federal funds sold increased $13.7 million as compared to the same period of 2008. S&T acquired $278.5 million of average loans and $147.3 million of average securities with the IBT acquisition. The yields on average loans decreased by 104 basis points from the comparable period in 2008 and the yield on average securities decreased by 29 basis points. Overall yields on interest-earning assets were 5.18 percent and 6.13 percent for the nine months ended September 30, 2009 and 2008, respectively.

For the nine months ended September 30, 2009, balances of average interest-bearing deposits increased by $336.7 million as compared to the same period of 2008. S&T acquired $326.0 million of average deposits with the IBT acquisition. The cost of deposits totaled 1.23 percent, a decrease of 66 basis points from the comparable period in 2008 due to lower rates paid on both core and time deposits. The cost of REPOs and other borrowed funds decreased 92 basis points to 2.56 percent as a result of lower short-term rates as compared to the same period of 2008. Overall funding costs decreased 88 basis points to 1.68 percent at September 30, 2009 as compared to September 30, 2008. Positively affecting net interest income was a $195.0 million increase in average net free funds during the nine months ended September 30, 2009 as compared to the same period of 2008. Average net free funds are the excess of demand deposits, other non-interest bearing liabilities and shareholders’ equity over nonearning assets. The increase is primarily due to successful marketing of new demand accounts and corporate cash management services and increased equity.

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. Maintaining consistent spreads between interest-earning assets and interest-bearing liabilities is very significant to our financial performance because net interest income comprised 78 percent of operating revenue (net interest income plus noninterest income, excluding security gains) in the nine months ended September 30, 2009 as compared to 79 percent for the same period of 2008. The level and mix of interest-earning assets and funds are continually monitored by ALCO in order to mitigate the interest-rate sensitivity 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 interest margin given the challenges of the current interest rate environment and the shifting yield curve.

The following table reconciles interest income per the consolidated statements of income to net interest income adjusted to a fully tax-equivalent basis:

Provision for Loan Losses

The provision for loan losses was $62.0 million for the nine months ended September 30, 2009 and $7.3 million for the same period of 2008. The $62.0 million provision for the first nine months of 2009 is primarily a result of net charge-offs of $43.8 million, a $10.8 million increase in specific reserves and a $7.4 million increase in general reserves.

The increase in specific reserves is primarily a result of the commercial credits discussed above. The increase in general reserves is primarily the result of an increase in overall risk (both macroeconomic and specific portfolio risks) combined with enhancements in methodology. Specifically, the increased macroeconomic risks were unemployment and commercial real estate vacancy trends, and the increased specific portfolio risks were nonaccrual loans, delinquent loans, classified loans, net charge-offs and delinquency trends, and out-of-state loans. All of these increases were partially offset by a decrease in loan growth during the first nine months of 2009.

In addition, during the first nine months of 2009, S&T introduced three enhancements in its methodology. The first enhancement was the addition of an out-of-state risk factor which increased the general reserves for commercial real estate loans. The second enhancement was the expansion of the risk rating scale assigned for the qualitative factors in response to the current economic environment, which also had the effect of increasing general reserves. The third enhancement was a change in the baseline for loss history from a seven year absolute high to a five year average combined with the qualitative adjusted factors. Management believes that these enhancements are more indicative of the loan losses over the economic life cycle of the loan segments.

The provision is the result of management’s assessment of credit quality statistics and other factors that would have an impact on probable losses in the loan portfolio, and the model used for determination of the adequacy of the allowance for loan losses. Changes within the allowance for loan loss model are directionally consistent with the increase in nonperforming loans and classified loan trends, loan charge-off levels and the impact of the aforementioned troubled commercial loan relationships during the first nine months of 2009.

Credit quality is the most important factor in determining the amount of the allowance for loan losses and the resulting provision. During the first nine months, S&T had an increase in delinquencies, classified and nonperforming loan levels, primarily due to the commercial credits discussed above and an overall slowdown in the economy that is affecting all segments of the loan portfolio. Also affecting the amount of the allowance for loan losses, and resulting provision, are increases in several qualitative risk factors within the loan loss reserve model based on observations regarding both economic conditions and changes in overall asset quality. For the nine months ended September 30, 2009, net loan charge-offs were $43.8 million compared to net loan charge-offs of $3.8 million for the nine months ended September 30, 2008. The most significant net charge-offs in 2009 were for a $26.5 million charge-off for the aforementioned $30.3 million commercial relationship with an energy exploration and drilling company, $8.2 million for three Florida lot development projects with a remaining exposure in Florida of $3.7 million, $2.7 million for a $3.5 million loan on a mixed use commercial property that lost a major tenant, $1.1 million charge-off for a $2.4 million office building that was foreclosed and sold during the first quarter of 2009, $1.1 million for a regional restaurant that entered into bankruptcy and $0.6 million for a multi-family development project in western Pennsylvania and $0.6 million for a retail sales company that discontinued operations due to cash flow problems. The most significant net loan charge-offs during the first nine months of 2008 were primarily impacted by a $1.1 million charge-off on a loan with a sales and service company in the second quarter of 2008 and $0.9 million charge-off on a construction company loan during the third quarter of 2008.

Noninterest Income

Noninterest income, excluding security losses, increased $3.0 million or 10 percent, to $32.3 million in the nine months ended September 30, 2009 as compared to the same 2008 period. Increases included $0.8 million or 10 percent in service charges on deposit accounts, $1.2 million in mortgage banking fees and $1.6 million or 24 percent in other noninterest income, offset by decreases of $0.2 million or 4 percent in insurance commissions, $0.3 million or 5 percent in wealth management fees and $0.1 million or 7 percent in letter of credit fees. The increase of $0.8 million or 10 percent in service charges on deposit fees is primarily related to the increased customer base resulting from the IBT acquisition, as well as the organic expansion of demand deposit accounts. The increase of $1.2 million in mortgage banking fees is a result of record performances in mortgage banking activities during the nine months ended September 30, 2009 as consumers sought to refinance existing loans at lower interest rates. The increase of $1.6 million in other noninterest income is primarily related to increased debit and credit card

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

revenues as a result of an increased customer base from the IBT acquisition, as well as the organic expansion of demand deposit accounts, deferred compensation plan valuations, offset by a $0.6 million charge for the additional credit exposure on an exited commercial swap asset. Decreases of $0.2 million in insurance commissions and $0.3 million in wealth management fees and are primarily attributable to current market conditions for these lines of business. The decrease of $0.1 million in letter of credit fees is attributable to customer preferences for this type of product.

S&T recognized $4.6 million of losses primarily on available for sale equity securities in the nine months ended September 30, 2009 as compared to $1.6 million of losses in the same period of 2008. The investment security losses for the nine months ended September 30, 2009 are primarily other-than-temporary impairment charges on eleven bank equity holdings totaling $4.1 million in accordance with FSP 115-2 and FASB No. 124-2 (ASC 320-10).

Noninterest Expense

Noninterest expense increased by $20.4 million or 32 percent during the nine months ended September 30, 2009 compared to the nine months ended September 30, 2008. Salaries and employee benefit expense increased $4.4 million or 13 percent primarily attributable to the addition of 103 full-time equivalent staff, mostly due to the addition of IBT retained staff, normal year-end merit increases and increased pension expenses as a result of market declines in the portfolio and increased medical plans expenses. Salaries and employee benefits were positively affected by reduced accruals for incentives in anticipation of decreased earnings performance for 2009 as well as a reduction in employee stock appreciation rights valuation expense resulting from a decrease in S&T stock fair value. Occupancy, furniture and equipment expense increased $0.9 million or 12 percent during the nine months ended September 30, 2009 as compared to the same period 2008, as a result of the net acquisition of new branches with the IBT acquisition. Other tax expense increased $0.6 million or 29 percent primarily as a result of increased Pennsylvania shares tax due to the IBT acquisition. Data processing expense increased $0.5 million or 11 percent as compared to the same period in 2008 as a result of changes in data communication processes and an increased customer base as a result of the IBT acquisition. Marketing expenses decreased $0.2 million due to special promotions related to the IBT acquisition. Amortization of intangibles increased $1.1 million due to the IBT acquisition. FDIC assessments increased by $6.6 million due to the special assessment charged to all banks in the second quarter of 2009, an increased premium ratio and a higher deposit base during the nine months ended September 30, 2009. Other noninterest expense increased $6.5 million or 51 percent during the nine months ended September 30, 2009 and is primarily attributable to a $2.0 million increase in unfunded loan commitments, a $1.6 increase in the amortization and impairment for affordable housing limited partnerships, a $1.7 million increase in consulting, legal and loan collection expenses primarily associated with troubled loans, a $0.9 million increase in other real estate owned expense and a $0.3 million accrual for litigation settlement. S&T’s efficiency ratio, which measures noninterest expense as a percent of noninterest income plus net interest income on a fully taxable equivalent basis, excluding security gains, was 57 percent for the nine months ended September 30, 2009 and 46 percent for the same period of 2008.

Federal Income Taxes

A federal income tax benefit of $6.5 million was recognized in the nine-month period ended September 30, 2009 attributable to the pretax loss of $7.8 million for the period, compared to expense of $16.7 million on pretax income of $61.1 million in the same period last year. Included in the 2009 tax benefit were discrete items of tax expense approximating $0.4 million, interest and penalties on a settled IRS examination, an increase in unrecognized tax benefits and return to provision adjustments. Discrete items in the 2008 period were immaterial.

S&T management ordinarily applies an annual effective tax rate, which is an annual forecast of tax expense as a percentage of expected full year income (an “annual effective tax rate approach”). Items unrelated to current year ordinary income are typically recognized entirely in the period they occur as a discrete item of tax. The quarterly income tax provision is ordinarily comprised of tax on ordinary income at the most recent estimated annual effective tax rate, adjusted for the effect of discrete items. S&T ordinarily generates an annual effective tax rate that is less than the statutory rate of 35% due to benefits resulting from tax-exempt interest, excludible dividend income, and tax benefits associated with Low Income Housing Tax Credit (“LIHTC”) and Federal Historic Tax Credit Projects, which are relatively consistent regardless of the level of pretax income.

S&T BANCORP, INC. AND SUBSIDIARIES

Item 2.

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

The consistent level of tax benefits that reduce S&T’s tax rate below the 35% statutory rate, coupled with relatively low levels of expected annual pretax income, produces a counterintuitive annual effective tax rate and a tax benefit that has little correlation to year-to-date results. Accordingly, the income tax benefit recognized in the quarter is the amount related to actual results and tax benefits generated in the nine month period ended September 30, 2009 using a “discrete period” approach, as permitted by FIN18 paragraph 82 (ASC 740-270).

RESULTS OF OPERATIONS

Three months ended September 30, 2009 compared to Three months ended September 30, 2008

Net Income

Net income was $7.7 million or $0.28 diluted earnings per share for the third quarter of 2009 as compared to $15.7 million or $0.57 diluted earnings per share for the same period of 2008. The decrease in net income and earnings per share for the third quarter 2009 is primarily due to higher provision for loan losses which was necessitated by the significant increase in loan charge-offs and the general deterioration of the credit quality in the loan portfolio, increased FDIC premiums and other-than-temporary impairments. The common return on average assets was 0.73 percent at September 30, 2009, as compared to 1.44 percent at September 30, 2008. The common return on average equity was 5.67 percent at September 30, 2009 compared to 13.93 percent for the same period of 2008.

Net Interest Income

On a fully tax-equivalent basis net interest income was $38.1 million, a $2.5 million or 6 percent decrease for the three months ended September 30, 2009 as compared to $40.6 million for the same period of 2008. The decrease in net interest income was primarily a result of a $124.5 million decrease in average interest-earning assets, reduced net interest margin and higher delinquent interest. The net interest margin on a fully taxable equivalent basis was 3.94 percent for the three months ended September 30, 2009 as compared to the 4.07 percent in the same period of 2008. The decrease in the net interest margin is primarily attributable to the effect of higher delinquent interest and the inability to reduce core deposit rates by the same level of reduction in other short-term rates, offset by the benefits from the IBT acquisition in the second quarter of 2008.

For the three months ended September 30, 2009, average loans decreased $49.1 million, and average securities and federal funds sold decreased $75.4 million as compared to the same period of 2008. The yields on average loans decreased by 83 basis points from the comparable period in 2009 and the yield on average securities decreased by 50 basis points. Overall yields on earning assets were 5.13 percent for the three months ending September 30, 2009 and 5.91 percent for the three months ending September 30, 2008.

For the three months ended September 30, 2009, balances of average interest-bearing deposits increased by $115.2 million as compared to the same period of 2008. The cost of interest-bearing deposits totaled 1.37 percent, a decrease of 59 basis points from the comparable period in 2008 due to decreased rates paid on both core and time deposits. The cost of REPOs and other borrowed funds decreased 37 basis points to 2.71 percent as a result of lower short-term rates. Overall funding costs decreased 69 basis points to 1.54 percent for the three months ended September 30, 2009 as compared to the same period of 2008.

Positively affecting net interest income was a $168.1 million increase in average net free funds during the third quarter of 2009 compared to the same period of 2008. Average net free funds are the excess of demand deposits, other non-interest bearing liabilities and shareholders’ equity over nonearning assets. The increase is primarily due to successful marketing of new demand accounts and corporate cash management services and increased retained earnings.

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 earning assets and interest-bearing liabilities is very significant to our financial performance because net interest income comprised 78 percent of operating revenue (net interest income plus noninterest income, excluding security gains) in the third quarter of 2009 and 79 percent in the same period of 2008. The level and mix of earning assets and funds are continually monitored by ALCO in order to mitigate the interest-rate sensitivity 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 interest margin given the challenges of the current interest rate environment.

Provision for Loan Losses

The provision for loan losses was $8.4 million for the three months ended September 30, 2009 and $6.2 million for the same period of 2008. The $8.4 million provision for the third quarter 2009 is primarily the result of net charge-offs of $5.4 million and $2.8 million increase in specific reserves.

The provision is the result of management’s assessment of credit quality statistics and other factors that would have an impact on probable losses in the loan portfolio, and the model used for determination of the adequacy of the allowance for loan losses. Changes within the allowance for loan loss model are directionally consistent with the increase in nonperforming loans and classified loan trends, loan charge-off levels and impact of the aforementioned troubled commercial loan relationships during the third quarter of 2009.

Credit quality is the most important factor in determining the amount of the allowance for loan losses and the resulting provision. Also affecting the amount of the allowance for loan losses, and the resulting provision, is the decrease in loan growth and portfolio composition. Net charged-off loans were $5.4 million and $1.7 million for the third quarter of 2009 and 2008, respectively. The most significant charge-offs for the third quarter of 2009 were $2.9 million on three Florida lot development projects with an remaining exposure in Florida of $3.7 million, $0.6 million for a multi-family development project in western Pennsylvania and $0.6 million for a retail sales company that discontinued operations. The most significant charge-off in the third quarter of 2008 was $0.9 million on a construction company loan.

Noninterest Income

Noninterest income, excluding security gains, decreased $0.3 million or 3 percent for the three months ended September 30, 2009 as compared to 2008. Mortgage banking decreased $0.4 million as a result of decreases in fair values of mortgage derivatives during the three months ended September 30, 2009. Service charges and fees decreased $0.3 million primarily attributable to reduced insufficient funds fees due to changing customer behavior patterns and wealth management fees decreased $0.2 million as a result of a decline in market values of customer accounts. Offsetting these decreases are increases of $0.1 million in letter of credit fees and insurance commissions. Other income increased $0.5 million in the third quarter of 2009 as compared to the same period of 2008, primarily due to increases in debit and credit card revenues resulting from an increased customer base from the IBT acquisition as well as the organic expansion of demand deposit accounts. Deferred

compensation plan valuations increase other income by $0.8 million. Also included in other income was the aforementioned $0.6 million reduction due to the additional credit exposure on an exited commercial swap asset.

S&T recognized $2.1 million of net losses primarily on available for sale equity securities in the three months ended September 30, 2009 as compared to $0.3 million of net losses in the same period of 2008. The investments security losses for the third quarter of 2009 are the result of $2.1 million of other-than-temporary impairment charges for seven bank equity securities. The $0.3 million of investment security losses in the same period of 2008 are a result of $2.6 million of other-than-temporary impairment charges for two bank equity holdings and $2.3 million of gains related to restructuring of the IBT debt securities portfolio.

Noninterest Expense

Noninterest expense increased by $2.5 million or 11 percent during the three months ended September 30, 2009 compared to the three months ended September 30, 2008. Salaries and employee benefit expense increased $0.6 million or 5 percent primarily attributable to the effects of year-end merit increases, increased pension expenses as a result of market declines in the portfolio and higher medical plan costs. Offsetting these increases are decreased accruals for incentives in anticipation of decreased earnings performance for 2009 as well as a reduction in employee stock appreciation rights valuation expense resulting from a decrease in S&T stock fair value. Average full-time equivalent staff was 943 at September 30, 2009 compared to 959 at September 30, 2008. Other taxes expense increased $0.3 million or 39 percent as a result of Pennsylvania educational tax credits utilized in the third quarter of 2008. Data processing expense increased $0.2 million or 15 percent in the third quarter of 2009 as compared to the third quarter of 2008, due to changes in data communication processes. FDIC assessment increased by $1.4 million due to an increased premium ratio and a higher deposit base in 2009.

S&T’s efficiency ratio, which measures noninterest expense as a percent of noninterest income plus net interest income on a fully taxable equivalent basis, excluding security gains, was 51 percent for the three months ended September 30, 2009 and 44 percent for the same period of 2008.

Federal Income Taxes

A federal income tax expense of $2.6 million was recognized in the three month period ended September 30, 2009 attributable to pretax income of $11.8 million for the period, compared to $5.2 million on pretax income of $20.9 million in the same period last year. Discrete items in the three month period ended September 30, 2009 were $(0.2) million which were related to return to provision adjustments and was immaterial for the same period of 2008.

As previously disclosed, S&T applied a discrete period approach to actual results for the quarter ending September 30, 2009 as the annual effective tax rate approach produced a counter intuitive result.

Critical Accounting Policies and Judgments

S&T’s consolidated financial statements are prepared based upon the application of certain critical accounting policies affecting accounts such as: securities, income taxes, joint ventures, allowance for loan losses, mortgage servicing rights valuations and goodwill and other intangibles. Certain of 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. S&T’s critical accounting policies are presented in Management’s Discussion and Analysis of Financial Condition and Results of Operations in S&T’s 2008 Annual Report on Form 10-K, as filed with the SEC on February 27, 2009. There have been no material changes in S&T’s critical accounting policies since December 31, 2008.

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;

•

credit losses;

•

sources of liquidity;

•

legislation affecting the financial services industry as a whole, and/or S&T and its subsidiaries individually or collectively;

•

regulatory supervision and oversight, including required capital levels;

•

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

•

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.

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.

Item 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ALCO monitors and manages interest-rate sensitivity through gap, rate shock analysis and simulations 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, 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 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 as of September 30, 2009.

Cumulative 6 months	1.09	0.87
Cumulative 12 months	1.06	0.92

S&T’s one-year repricing gap at September 30, 2009 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.

S&T BANCORP, INC. AND SUBSIDIARIES

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK - continued

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. The rate shock incorporates management assumptions regarding the level of interest rate changes on non-maturity deposit products (savings, money market and NOW and demand deposits) 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.

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

Percent Change to Pretax Net Interest Income	+300 bps		-300 bps
September 30, 2009	6.95	%	(5.91	)%
December 31, 2008	(0.72	) %	0.73	%

When comparing September 2009 to December 2008, the impact on pretax net interest income in the +300 basis point rate shock scenario improved. This improvement is mainly attributed to a decrease in short term variable rate borrowings. The decrease in short term variable rate borrowings is due to participation in the Capital Purchase Program and a decline in asset volume.

When comparing September 2009 to December 2008, the impact on pretax net interest income in the -300 basis point rate shock scenario decreased. The decrease is a result of a reduction in short term variable rate borrowings due to participation in the Capital Purchase Program and deposit rates that are closer to their floors.

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 September 30, 2009. 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 September 30, 2009, 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.
