Part I

Item 1. BUSINESS

General

S&T Bancorp, Inc. (“S&T”; references to “we” or “us” refers to S&T, including on a consolidated basis with our subsidiaries where appropriate) was incorporated on March 17, 1983 under the laws of the Commonwealth of Pennsylvania as a bank holding company and has two wholly owned subsidiaries, S&T Bank and 9th Street Holdings, Inc. S&T owns a one-half interest in Commonwealth Trust Credit Life Insurance Company (“CTCLIC”). S&T is registered as a financial holding company with the Board of Governors of the Federal Reserve System under the Bank Holding Company Act of 1956, as amended (“BHCA”).

As of December 31, 2007, S&T had approximately $3.4 billion in total assets, $337.6 million in total shareholder’s equity and $2.6 billion in total deposits. S&T Bank deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”) to the maximum extent provided by law.

S&T Bank is a full service bank with its Main Office at 800 Philadelphia Street, Indiana, Pennsylvania, providing services to its customers through a branch network of 46 offices located in Allegheny, Armstrong, Blair, Butler, Cambria, Clarion, Clearfield, Indiana, Jefferson and Westmoreland counties of Pennsylvania.

S&T Bank’s services include accepting time and demand deposit accounts, originating commercial and consumer loans, providing letters of credit, offering discount brokerage services, personal financial planning, credit card services and insurance products. Management believes that S&T Bank has a relatively stable deposit base and no material amount of deposits is obtained from a single depositor or group of depositors (including federal, state and local governments). S&T Bank has not experienced significant fluctuations in deposits.

Total wealth management assets under management were approximately $1.3 billion at December 31, 2007. Wealth management services include services as executor and trustee under wills and deeds, as guardian and custodian of employee benefits and other trusts and brokerage services.

S&T Bank has four wholly owned subsidiaries, S&T Insurance Group, LLC, S&T Bancholdings, Inc., S&T Professional Resources Group, LLC and Stewart Capital Advisors, LLC. In May 2002, S&T Professional Resources Group, LLC was formed to market software developed by S&T Bank. In August 2002, S&T Bancholdings, Inc. was formed as an investment holding company. In August 2002, S&T Bank acquired Evergreen Insurance Associates, Inc., a multi-line insurance agency with a client base in Pennsylvania, Maryland and West Virginia. Evergreen Insurance Associates, Inc. was merged into Evergreen Acquisition, LLC, with a resulting name change to Evergreen Insurance Associates, LLC (“Evergreen”), a wholly owned subsidiary of S&T Insurance Group, LLC. Evergreen provides insurance programs structured to the individual needs of its customers, and offers a full line of commercial property and casualty insurance, group life and health coverage, employee benefit solutions as well as personal insurance. Stewart Capital Advisors, LLC, formed in August 2005, is a registered investment advisor that manages private investment accounts for individuals and institutions and advises the Stewart Capital Mutual Funds.

Pending Acquisition

On December 17, 2007, S&T announced that it would acquire IBT Bancorp, Inc., of Irwin, Pennsylvania (“IBT”), in a stock and cash transaction valued at approximately $171 million as of that date. The transaction is an in-market transaction that will expand S&T’s existing footprint in the Westmoreland and Allegheny counties of Pennsylvania. The combined company will have over $4.1 billion in assets and increase its market share from 5 percent to approximately 12 percent in Westmoreland County. IBT shareholders will receive either $31.00 cash or between 0.93 and 0.97 of a fraction of a share of S&T common stock for each of their shares of IBT common stock, with the precise fraction of a share based upon the average high and low sale price for S&T common stock for a twenty trading day period preceding the date of the meeting of IBT shareholders at which the merger will be considered.

Employees

As of December 31, 2007, S&T and its subsidiaries had 806 full-time equivalent employees. S&T provides a variety of employment benefits and considers its relationship with its employees to be good.

Supervision and Regulation

General

S&T and S&T Bank are each extensively regulated under federal and state law. The following describes certain aspects of such regulation and does not purport to be a complete description of all regulations that affect S&T or all aspects of such regulations.

To the extent statutory or regulatory provisions are described, the description is qualified in its entirety by reference to the particular statutory or regulatory provisions. Proposals to change the laws and regulations governing the banking industry are frequently raised in Congress, in state legislatures and before the various bank regulatory agencies. The likelihood and timing of any changes and the impact such changes might have on S&T or S&T Bank is impossible to determine with any certainty.

Any change in applicable laws or regulations, or in the way such laws or regulations are interpreted by regulatory agencies or courts, may have a material impact on our business, operations and earnings.

S&T

S&T is a bank holding company subject to regulation under the BHCA, and the examination and reporting requirements of the Federal Reserve System (the “Federal Reserve Board”). Under the BHCA, a bank holding company may not directly or indirectly acquire ownership or control of more than five percent of the voting shares or substantially all of the assets of any additional bank, or merge or consolidate with another bank holding company, without the prior approval of the Federal Reserve Board. As noted, on December 17, 2007, S&T announced that it would acquire IBT. Consummation of the transaction is subject to receipt by S&T of required regulatory approvals. S&T has applied for or is in the process of applying for such approvals.

In addition, S&T has received such approvals from the Federal Reserve Board for the following passive ownership positions:

Name of Entity	% Approved		% of Outstanding Shares Owned by S&T
Allegheny Valley Bancorp, Inc.	24.9	%	14.8	%
CBT Financial Corp.	9.9	%	5.4	%
IBT Bancorp, Inc.	9.9	%	8.1	%

S&T elected to become a financial holding company under the BHCA in 2001 and thereby engage in a broader range of financial and other activities than are permissible for traditional bank holding companies. In order to qualify and maintain its status as a financial holding company, the depository institutions controlled by S&T must remain “well capitalized” and “well managed” (as defined in federal law), and have at least a “satisfactory” Community Reinvestment Act (“CRA”) rating. S&T and S&T Bank currently satisfy these criteria. No regulatory approval is required for a financial holding company to acquire a company, other than a bank or savings association, engaged in activities that are financial in nature or incidental to activities that are financial in nature, as determined by the Federal Reserve Board. The BHCA identifies several activities as “financial in nature” including, among others, securities underwriting, dealing and market making; sponsoring mutual funds and investment companies; insurance underwriting and sales agency; investment advisory activities; merchant banking activities; and activities that the Federal Reserve Board has determined to be closely related to banking or a proper incident thereto. Banks also may engage, subject to limitations on investment, in activities that are financial in nature, other than insurance underwriting, insurance company portfolio investment, real estate development and real estate investment, through a financial subsidiary of the bank, if the bank is well capitalized, well managed and has at least a “satisfactory” CRA rating.

4

Item 1. BUSINESS - continued

If S&T Bank ceases to be “well capitalized” or “well managed,” S&T will not be in compliance with the requirements of the BHCA regarding financial holding companies. If a financial holding company is notified by the Federal Reserve Bank of such a change in the ratings of any of its subsidiary banks, it must take certain corrective actions within specified time frames. Furthermore, if S&T Bank were to receive a CRA rating of less than “satisfactory,” then S&T would be prohibited from engaging in new activities or acquiring companies other than bank holding companies, banks or savings associations until the rating is raised to “satisfactory” or better.

S&T is presently engaged in nonbanking activities through the following six entities: 9th Street Holdings, Inc., S&T Bancholdings, Inc., CTCLIC, S&T Insurance Group, LLC, S&T Professional Resources Group, LLC and Stewart Capital Advisors, LLC. 9th Street Holdings, Inc. was formed in June 1988 and S&T Bancholdings, Inc. was formed in August 2002 to hold and manage a group of investments previously owned by S&T Bank and to give S&T additional latitude to purchase other investments. CTCLIC, which is a joint venture with another financial institution, acts as a reinsurer of credit life, accident and health insurance policies sold by S&T Bank and the other institution. S&T Insurance Group, LLC distributes high-quality life insurance and long-term disability income insurance products. During 2002, S&T Insurance Group, LLC expanded into the property and casualty insurance business with the acquisition of Evergreen Insurance Associates, LLC. S&T Professional Resources Group, LLC markets software developed by S&T Bank. Stewart Capital Advisors, LLC, formed in August 2005, is a registered investment advisor that manages private investment accounts for individuals and institutions and advises the Stewart Capital Mutual Funds. S&T also is subject to the supervision and regulation of the Pennsylvania Department of Banking (“PADB”).

S&T Bank

As a state-chartered, commercial bank, the deposits of which are insured by the FDIC, S&T Bank is subject to the supervision and regulation of the PADB and the FDIC. S&T Bank also is subject to various requirements and restrictions under federal and state law, including requirements to maintain reserves against deposits, restrictions on the types, amount and terms and conditions of loans that may be granted, and limits on the type of other activities in which S&T Bank may engage and the investments it may make.

S&T Bank also is subject to federal laws that limit the amount of transactions between itself and S&T or S&T’s nonbank subsidiaries. Under these provisions, transactions by a bank with its parent company or any nonbank affiliate generally are limited to 10 percent of the bank subsidiary’s capital and surplus or 20 percent in the aggregate. Further, loans and extensions of credit generally are required to be secured by eligible collateral in specified amounts. Federal law also imposes similar restrictions on transactions between a bank and its financial subsidiaries. A bank, such as S&T Bank, is prohibited from purchasing any “low quality” asset from an affiliate. S&T Bank is in compliance with these provisions.

Insurance of Accounts; Depositor Preference

The deposits of S&T Bank are insured up to applicable limits per insured depositor by the FDIC. As an FDIC-insured bank, S&T Bank also is subject to FDIC insurance assessments. As a result of the Federal Deposit Insurance Reform Act of 2005, the FDIC adopted a revised risk-based assessment system to determine assessment rates to be paid by member institutions such as S&T Bank. Under this revised assessment system, risk is defined and measured using an institution’s supervisory ratings with certain other risk measures, including certain financial ratios. The annual rates for 2008 for institutions in risk category I range from 5 to 7 basis points, the rate for institutions in risk category II is 10 basis points and the rate for institutions in risk category III is 28 basis points. These rates may be offset by a one time assessment credit held by an institution, based on the assessment base of that institution as of December 31, 1996, and in the future by dividends that may be declared by the FDIC if the deposit reserve ratio increases above a certain amount. The FDIC may raise or lower these assessment rates based on various factors to achieve a reserve ratio, which the FDIC currently has set at 1.25 percent of insured deposits.

In addition to deposit insurance fund assessments, the FDIC assesses all insured deposits a special assessment to fund the repayment of debt obligations of the Financing Corporation (FICO). FICO is a government-sponsored entity that was formed to borrow the money necessary to carry out the closing and ultimate disposition of failed thrift institutions by the Resolution Trust Corporation. At December 31, 2007, the annualized rate established by the FDIC for the FICO assessment was 1.14 basis points per $100 of insured deposits.

Under federal law, deposits and certain claims for administrative expenses and employee compensation against insured depository institutions are afforded a priority over other general unsecured claims against such an institution, including federal funds and letters of credit, in the liquidation or other resolution of such an institution by any receiver appointed by regulatory authorities. Such priority creditors would include the FDIC.

Item 1. BUSINESS - continued

Capital

The Federal Reserve Board and the FDIC have issued substantially similar risk-based and leverage capital guidelines applicable to banking organizations they supervise. Under the risk-based capital requirements, both S&T and S&T Bank generally are required to maintain a minimum ratio of total capital to risk-weighted assets (including certain off-balance sheet activities, such as standby letters of credit) of 8.00 percent. At least half of the total capital must be composed of common equity, retained earnings and qualifying perpetual preferred stock, less certain intangibles (“Tier 1 capital”). The remainder may consist of certain subordinated debt, certain hybrid capital instruments and other qualifying preferred stock, and a limited amount of the loan loss allowance (“Tier 2 capital” and, together with Tier 1 capital, “Total capital”). At December 31, 2007, S&T’s Tier 1 and Total capital ratios were 9.50 percent and 11.64 percent, respectively, and the ratios of Tier 1 capital and Total capital to total risk-adjusted assets for S&T Bank were 8.68 percent and 10.72 percent, respectively.

In addition, each of the federal bank regulatory agencies has established minimum leverage capital ratio requirements for banking organizations. These requirements provide for a minimum leverage ratio of Tier 1 capital to adjusted average quarterly assets equal to 3.00 percent for bank and bank holding companies that meet certain specified criteria, including that they have the highest regulatory rating and are not experiencing significant growth or expansion. All other banks and bank holding companies generally are required to maintain a leverage ratio of at least 100 to 200 basis points above the stated minimum. At December 31, 2007, S&T’s leverage ratio was 8.57 percent, and S&T Bank’s leverage ratio was 7.82 percent.

Both the Federal Reserve Board and the FDIC’s risk-based capital standards explicitly identify concentrations of credit risk and the risk arising from non-traditional activities, as well as an institution’s ability to manage these risks, as important factors to be taken into account by the agency in assessing an institution’s overall capital adequacy. The capital guidelines also provide that an institution’s exposure to a decline in the economic value of its capital due to changes in interest rates be considered by the agency as a factor in evaluating a bank’s capital adequacy. The Federal Reserve Board also has issued additional capital guidelines for certain bank holding companies that engage in trading activities. S&T does not believe that consideration of these additional factors will affect the regulators’ assessment of S&T or S&T Bank’s capital position.

Payment of Dividends

S&T is a legal entity separate and distinct from its banking and other subsidiaries. A substantial portion of S&T’s revenues consists of dividend payments it receives from S&T Bank. S&T Bank, in turn, is subject to state laws and regulations that limit the amount of dividends it can pay to S&T. In addition, both S&T and S&T Bank are subject to various general regulatory policies relating to the payment of dividends, including requirements to maintain adequate capital above regulatory minimums. The Federal Reserve Board has indicated that banking organizations should generally pay dividends only if (1) the organization’s net income available to common shareholders over the past year has been sufficient to fund fully the dividends and (2) the prospective rate of earnings retention appears consistent with the organization’s capital needs, asset quality and overall financial condition. S&T does not expect that any of these laws, regulations or policies will materially influence S&T or S&T Bank’s ability to pay dividends. During the year ended December 31, 2007, S&T Bank paid $45.2 million in cash dividends to S&T.

Other Safety and Soundness Regulations

There are a number of obligations and restrictions imposed on bank holding companies such as S&T and its depository institution subsidiary by federal law and regulatory policy that are designed to reduce potential loss exposure to the depositors of such depository institutions and to the FDIC insurance funds in the event the depository institution becomes in danger of default or in default. Under current federal law for example, the federal banking agencies possess broad powers to take prompt corrective action to resolve problems of insured depository institutions. The extent of these powers depends upon whether the institution in question is “well capitalized,” “adequately capitalized,” “undercapitalized,” “significantly undercapitalized,” or “critically undercapitalized,” as defined by the law. Under regulations established by the federal banking agencies, a “well capitalized” institution must have a Tier 1 capital ratio of at least 6.00 percent, a Total capital ratio of at least 10.00 percent and a leverage ratio of at least 5.00 percent and not be subject to a capital directive or order. An “adequately capitalized” institution must have a Tier 1 capital ratio of at least 4.00 percent, a Total capital ratio of at least 8.00 percent and a leverage ratio of at least 4.00 percent, or 3.00 percent in some cases. As of December 31, 2007, S&T Bank was classified as “well capitalized.” The classification of depository institutions is primarily for the purpose of applying the federal banking agencies’ prompt corrective action provisions and is not intended to be and should not be interpreted as a representation of overall financial condition or prospects of any financial institution.

6

Item 1. BUSINESS - continued

The federal banking agencies’ prompt corrective action powers (which increase depending upon the degree to which an institution is undercapitalized) can include, among other things, requiring an insured depository institution to adopt a capital restoration plan which cannot be approved unless guaranteed by the institution’s parent company; placing limits on asset growth and restrictions on activities, including restrictions on transactions with affiliates; restricting the interest rates the institution may pay on deposits; prohibiting the payment of principal or interest on subordinated debt; prohibiting the holding company from making capital distributions without prior regulatory approval; and, ultimately, appointing a receiver for the institution. Among other things, only a “well capitalized” depository institution may accept brokered deposits without prior regulatory approval. In addition to the foregoing, current Federal Reserve Board policy with respect to bank holding company operations requires a bank holding company to serve as a source of financial strength to its subsidiary depository institutions and to commit resources to support such institutions in circumstances where it might not do so otherwise.

The federal banking agencies also have adopted guidelines prescribing safety and soundness standards relating to internal controls and information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth and compensation, fees and benefits. In general, the guidelines require, among other things, appropriate systems and practices to identify and manage the risks and exposures specified in the guidelines. The guidelines prohibit excessive compensation as an unsafe and unsound practice and describe compensation as excessive when the amounts paid are unreasonable or disproportionate to the services performed by an executive officer, employee, director or principal shareholder. In addition, the agencies adopted regulations that authorize, but do not require, an agency to order an institution that has been given notice by an agency that it is not in compliance with any of such safety and soundness standards to submit a compliance plan. If, after being so notified, an institution fails to submit an acceptable compliance plan, the agency must issue an order directing action to correct the deficiency and may issue an order directing other actions of the types to which an undercapitalized institution is subject under the prompt corrective action provisions described above.

Regulatory Enforcement Authority

The enforcement powers available to federal banking agencies are substantial and include, among other things and in addition to other powers described herein, the ability to assess civil money penalties, to issue cease-and-desist or removal orders and to initiate injunctive actions against banks and bank holding companies and “institution affiliated parties,” as defined in the Federal Deposit Insurance Act (“FDIA”). In general, these enforcement actions may be initiated for violations of laws and regulations and unsafe or unsound practices. Other actions or inactions may provide the basis for enforcement action, including misleading or untimely reports filed with regulatory authorities.

The PADB also has broad enforcement powers over S&T Bank, including the power to impose fines and other civil and criminal penalties, and to appoint a conservator or receiver.

Interstate Banking and Branching

The BHCA currently permits bank holding companies from any state to acquire banks and bank holding companies located in any other state, subject to certain conditions, including certain nationwide and state-imposed deposit concentration limits. S&T Bank has the ability, subject to certain restrictions, to acquire by acquisition or merger, branches of banks located outside of Pennsylvania, its home state. The establishment of de novo interstate branches is also possible in those states where expressly permitted. Once a bank has established branches in a state through an interstate merger transaction, the bank may establish and acquire additional branches at any location in the state where a bank headquartered in that state could have established or acquired branches under applicable federal or state law.

Community Reinvestment and Consumer Protection Laws

In connection with its lending activities, S&T Bank is subject to a number of federal laws designed to protect borrowers and promote lending to various sectors of the economy and population. These include the Equal Credit Opportunity Act, the Truth-in-Lending Act, the Home Mortgage Disclosure Act, the Real Estate Settlement Procedures Act, the Fair Credit Reporting Act and the CRA. In addition, rules developed by the federal banking agencies pursuant to federal law require disclosure of privacy policies to consumers and in some circumstances, allow consumers to prevent the disclosure of certain personal information to nonaffiliated third parties.

7

Item 1. BUSINESS - continued

The CRA requires the appropriate federal banking agency, in connection with its examination of a bank, to assess the bank’s record in meeting the credit needs of the communities served by the bank, including low and moderate-income neighborhoods. Furthermore, such assessment also is required of any bank that has applied, among other things, to merge or consolidate with or acquire the assets or assume the liabilities of an insured depository institution, or to open or relocate a branch office. In the case of a bank holding company (including a financial holding company) applying for approval to acquire a bank or bank holding company, the Federal Reserve Board will assess the record of each subsidiary bank of the applicant bank holding company in considering the application. Under the CRA, institutions are assigned a rating of “outstanding,” “satisfactory,” “needs to improve” or “unsatisfactory.” S&T Bank was rated “satisfactory” in its most recent CRA evaluation.

Anti-Money Laundering Legislation

S&T Bank is subject to the Bank Secrecy Act and its implementing regulations and other anti-money laundering laws and regulations, including the USA PATRIOT Act of 2001. Among other things, these laws and regulations require S&T Bank to take steps to prevent the use of S&T Bank to facilitate the flow of illegal or illicit money, to report large currency transactions and to file suspicious activity reports. S&T Bank also is required to develop and implement a comprehensive anti-money laundering compliance program. Banks also must have in place appropriate “know your customer” policies and procedures. Violations of these requirements can result in substantial civil and criminal sanctions. In addition, provisions of the USA PATRIOT Act require the federal financial institution regulatory agencies to consider the effectiveness of a financial institution’s anti-money laundering activities when reviewing bank mergers and bank holding company acquisitions.

Competition

S&T Bank competes with other local, regional and national financial service providers, such as other financial holding companies, commercial banks, savings associations, credit unions, finance companies and brokerage and insurance firms. The financial service industry is likely to become more competitive as further technological advances enable more companies to provide financial services on a more efficient and convenient basis.

Item 1A. RISK FACTORS

Investments in S&T common stock involve risk. The following discussion highlights risks management believes are material for our company, but does not necessarily include all risks that S&T may face.

The market price of S&T common stock may fluctuate significantly in response to a number of factors, including:

• changes in securities analysts’ estimates of financial performance

• volatility of stock market prices and volumes

• changes in market valuations of similar companies

• changes in conditions in credit markets

• new products or services offered in the banking and/or financial services industries

• variations in quarterly or annual operating results

• new litigation

• changes in accounting policies or procedures as may be required by the Financial Accounting Standards Board (“FASB”) or other regulatory agencies

If S&T does not adjust to changes in the financial services industry, its financial performance may suffer.

S&T’s future financial performance will depend in part on its ability to expand its scope of available financial services to its customers. In addition to other banks, competitors include security dealers, brokers, mortgage bankers, investment advisors, and finance and insurance companies. The increasingly competitive environment is, in part, a result of changes in regulation, changes in technology and product delivery systems, and the accelerating pace of consolidation among financial service providers.

8

Item 1A. RISK FACTORS - continued

Future governmental regulation and legislation could limit our growth.

S&T is subject to extensive state and federal regulation, supervision and legislation that govern nearly every aspect of our operations. Changes to these laws could affect our ability to deliver or expand our services and diminish the value of our business. See “Supervision and Regulation” for additional information.

Interest rate movements impact the earnings of S&T.

S&T is exposed to interest rate risk, through the operations of its banking subsidiary, since substantially all of S&T Bank’s assets and liabilities are monetary in nature. Interest rate risk arises from market driven fluctuations in interest rates that affect cash flows, income, expense and value of financial instruments. S&T Bank’s earnings, like that of most financial institutions, largely depend on net interest income, which is the difference between the interest income earned on interest-earning assets, such as loans and investments, and the interest expense paid on interest-bearing liabilities, such as deposits and borrowings. In an increasing interest rate environment, the cost of funds sometimes increases more rapidly than the interest earned on the loans and securities because the primary source of funds are deposits with generally shorter maturities than the maturities on loans and investment securities. This could cause the net interest rate spread to compress and negatively impact S&T Bank’s profitability.

S&T’s business strategy includes growth plans through internal growth and acquisitions. Our financial condition and results of operations could be negatively affected if we fail to grow or fail to manage our growth effectively.

S&T intends to continue pursuing a profitable growth strategy. Our prospects must be considered in light of the risks, expenses and difficulties frequently encountered by companies in growth stages of development. We cannot assure you that we will be able to expand our market presence in our existing markets or successfully enter new markets or that any such expansion will not adversely affect our results of operations. Failure to manage our growth effectively could have a material adverse effect on our business, future prospects, financial condition or results of operations and could adversely affect our ability to successfully implement our business strategy. Also, if we grow more slowly than anticipated, our operating results could be materially adversely affected.

Our ability to grow successfully will depend on a variety of factors including the continued availability of desirable business opportunities, the competitive responses from other financial institutions in our market areas and our ability to manage our growth. There can be no assurance that growth opportunities will be available or that growth will be successfully managed.

Weakness in the economy and in the real estate market may adversely affect S&T.

If the strength of the U.S. economy or the real estate market in general declines, this could result in, among other things, a deterioration in credit quality or a reduced demand for credit, including a resultant effect on S&T’s loan portfolio and allowance for loan losses.

Downturn in the local economies may adversely affect our business.

S&T’s business is concentrated in the western-Pennsylvania area. As a result, its financial condition, results of operations and cash flows are subject to changes if there are changes in the economic conditions in this area. A prolonged period of economic recession or other adverse economic conditions in this area could have a negative impact on S&T. S&T can provide no assurance that conditions in its market area economies will not deteriorate in the future and that such deterioration would not have a material adverse effect on S&T.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

S&T is a financial holding company with its headquarters located in Indiana, Pennsylvania with assets of approximately $3.4 billion at December 31, 2007. S&T provides a full range of financial services through a branch network of 46 offices located in Allegheny, Armstrong, Blair, Butler, Cambria, Clarion, Clearfield, Indiana, Jefferson and Westmoreland counties of Pennsylvania. S&T provides full service retail and commercial banking products as well as cash management services; insurance; estate planning and administration; employee benefit investment management and administration; corporate services; and other fiduciary services. S&T earns revenue primarily from interest on loans, security investments and fees charged for financial services provided to our customers. Offsetting these revenues are the cost of deposits and other funding sources, provision for loan losses as well as other operating costs such as: salaries and employee benefits, occupancy, data processing expenses and tax expense. Balance sheet growth in 2007 included a 4 percent increase in commercial lending activities, an 8 percent increase in consumer and residential mortgage loans, with funding for that growth provided primarily by a 6 percent increase in borrowings and a 2 percent increase in deposits. S&T’s strategic plan to deliver profitable growth to our shareholders includes: increasing loans and core deposits with sufficient interest rate spreads, controlling loan delinquency and loan losses, controlling operating expenses and expanding the business through new de novo branching, merger and acquisitions, introduction of new products and services, and expansion of our products and services provided to our existing customers.

On December 17, 2007, S&T announced that it would acquire IBT, in a stock and cash transaction valued at approximately $171 million as of that date. The transaction is an in-market transaction that will expand S&T’s existing footprint in the Westmoreland and Allegheny counties of Pennsylvania. The combined company will have over $4.1 billion in assets and increase its market share from 5 percent to approximately 12 percent in Westmoreland County. IBT shareholders will receive either $31.00 cash or between 0.93 and 0.97 of a fraction of a share of S&T common stock for each of their shares of IBT common stock, with the precise fraction of a share based upon the average high and low sale price for S&T common stock for a twenty trading day period preceding the date of the meeting of IBT shareholders at which the merger will be considered.

There are many uncertainties regarding the economy as S&T enters 2008. S&T continually strives to be well positioned for changes in both the economy and interest rates, regardless of the timing or direction of these changes. Management continually assesses our balance sheet, capital, liquidity and operation infrastructures in order to be positioned to take advantage of internal or acquisition growth opportunities.

There are many factors that could influence our results, both positively and negatively, in 2008. Because the majority of our revenue comes from net interest income, internally generated loan and deposit growth and the mix of that growth are major factors on our operations and financial condition. S&T has directed a fair amount of focus and resources in planning for 2008 to improve our generation and retention of low cost core deposits. On the other hand, a slowing economy could cause

14

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

deterioration in the asset quality measurements. S&T recognizes that our shift to a greater dependence on commercial loans in recent years exposes us to larger credit risks and greater swings in nonperforming loans and loan charge-offs when problems do occur.

FINANCIAL CONDITION

Average earning assets increased by $77.8 million in 2007 primarily as a result of growth in commercial lending, consumer and residential mortgage activities. During 2007, average loan balances increased by $143.6 million, and average securities, other investments and federal funds sold decreased $65.8 million. The funding for this loan growth was primarily provided by a $90.6 million increase in average deposits and a $12.6 million increase in average borrowings, offset by a decrease of $16.2 million in average earnings retained due to a successful stock buyback program in 2007.

LENDING ACTIVITY

Average loans for the year ended December 31, 2007 were $2.7 billion, a $143.6 million or 6 percent increase from the year ended December 31, 2006. The increase in average loans for 2006 compared to the year ended 2005 was $217.3 million or 9 percent. Changes in the composition of the average loan portfolio during 2007 included increases of $90.6 million in commercial loans, $47.9 million in residential mortgage loans and $5.1 million in installment loans. Changes in the composition of the average loan portfolio during 2006 included increases of $163.2 million in commercial loans and $53.1 million in residential mortgage loans, offset by a decrease of $1.0 million in installment loans. Total loans at December 31, 2007 increased $130.6 million from December 31, 2006. The increase is primarily attributable to the growth of $81.5 million in commercial loans, $47.4 million in residential mortgage loans and $1.7 million in consumer loans.

Average real estate construction and commercial loans, including commercial and industrial, comprised 75 and 76 percent of the loan portfolio in 2007 and 2006, respectively. Commercial loans continued to be an area of strategic growth during 2007 and 2006. Although commercial loans can have a relatively higher risk profile, management believes these risks are mitigated through active portfolio management, underwriting and continuous review. At December 31, 2007, variable-rate commercial loans were 48 percent of the commercial loan portfolio as compared to 49 percent at December 31, 2006.

Average residential mortgage loans comprised 22 percent of the loan portfolio in 2007 and 21 percent in 2006. Residential mortgage lending continued to be a strategic focus during 2007 through a centralized mortgage origination department, ongoing product redesign, secondary market activities and the utilization of commission compensated originators. Management believes the downturn in the local residential real estate market and the impact of declining values on the real estate loan portfolio will be mitigated because of S&T’s conservative mortgage lending policies for portfolio loans, which generally require a maximum term of 20 years for fixed-rate mortgages, a maximum term of 30 years for adjustable-rate mortgages and private mortgage insurance for loans with less than a 20 percent down payment. Adjustable-rate mortgages with repricing terms of one, three and five years and floating rate mortgages comprised 10 percent of the residential mortgage portfolio in 2007 and 2006. Home equity loans increased $24.5 million during 2007 and $42.4 million in 2006 and totaled $294.4 million at December 31, 2007 and $269.9 million at December 31, 2006. The increase in home equity loans is primarily attributable to successful marketing programs during 2007 and 2006.

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 intent of 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 2007, S&T sold $17.4 million of 1–4 family mortgage loans to Fannie Mae and currently services $178.9 million of secondary market mortgage loans. Fees and gains from mortgage servicing activities were $0.6 million in 2007 and $0.7 million in 2006. Management 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.

15

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

Average consumer installment loans comprised 3 percent of the loan portfolio in 2007 and 2006. Installment loan increases during 2007 were primarily the result of successful marketing programs during 2007. The balance of consumer installment loans at December 31, 2007 was $74.8 million compared to $73.1 million at December 31, 2006.

Loan underwriting standards for S&T are established by a formal policy administered by the S&T Bank Loan Administration Department, and are subject to the periodic review and approval by our Board of Directors.

Rates and terms for commercial real estate, equipment loans and commercial lines of credit normally are negotiated, subject to such variables as financial condition of the borrower, economic conditions, marketability of collateral, credit history of the borrower and future cash flows. The loan to value policy guidelines for commercial real estate loans is generally 65–80 percent.

The loan to value policy guidelines for residential, first lien, mortgage loans is 80 percent. Higher loan to value loans may be approved with the appropriate private mortgage insurance coverage. Second lien positions are sometimes assumed with home equity loans, but normally only to the extent that the combined credit exposure for both first and second liens does not exceed 100 percent of the fair market value of the mortgage property.

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

SECURITIES ACTIVITY

Average securities and other investments decreased $64.6 million in 2007 and $49.8 million in 2006. The components of the 2007 decrease included $34.7 million in U.S. government agency securities, $14.4 million in marketable equity securities, $9.0 million of mortgage-backed securities, $3.3 million of corporate securities, $2.5 million of states and political subdivisions and $0.2 million in treasury securities. Average other investments decreased $0.5 million in 2007 as compared to the 2006 full year average and are comprised of Federal Home Loan Bank (“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 depends upon S&T’s borrowing availability and level from the FHLB. The components of the 2006 decrease included $24.6 million in U.S. government agency securities, $8.6 million in marketable equity securities, $7.7 million of mortgage-backed securities, $6.8 million of corporate securities and $2.9 million in treasury securities. Average other investments decreased $3.4 million in 2006 as compared to the 2005 full year average and are comprised of FHLB stock. Offsetting these decreases was an average increase of $4.2 million of states and political subdivisions. Both the decreases in securities in 2007 and 2006 are partially attributable to an S&T Asset Liability Committee (“ALCO”) strategy to reduce balances in both securities and borrowings to mitigate the interest rate risk of a flat or inverted yield curve.

The equity securities portfolio is primarily comprised of bank holding companies. At December 31, 2007, the equity securities portfolio had a total market value of $41.3 million and net unrealized gains of $7.5 million. The equity securities portfolio consists of securities traded on the various stock markets and is subject to changes in market value.

S&T’s policy for security classification includes U.S. treasury securities, U.S. government corporations and agencies, mortgage-backed securities, 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 market value in accordance with FSP 115-1 and FAS 124-1, “The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments”. During 2007, there were $0.1 million of realized losses taken for other-than-temporary impairments on three equity investment securities. The performance of the equities and debt securities markets could generate further impairment in future periods. At December 31, 2007, net unrealized gains on securities classified as available for sale, including equity securities, were approximately $8.4 million as compared to $9.8 million at December 31, 2006. S&T has the intent and ability to hold debt securities until maturity or until market value recovers above cost, and has the intent and ability to hold equity securities until market value recovers above cost.

S&T invests in various securities in order to provide a source of liquidity, increase net interest income and as a tool of ALCO to quickly reposition the balance sheet for interest rate risk purposes. Securities are subject to similar interest rate and credit risks as loans. In addition, by their nature, securities classified as available for sale are also subject to market value risks that could negatively affect the level of liquidity available to S&T, as well as equity.

Risks associated with various securities portfolios are managed and monitored by investment policies annually approved by the S&T Board of Directors, and administered through ALCO and the Treasury function of S&T Bank. As of December 31, 2007, management is not aware of any risk associated with securities that would be expected to have a significant, negative effect on S&T’s statement of condition or statement of operations.

NONINTEREST EARNING ASSETS

Average noninterest earning assets increased $11.3 million in 2007 and $20.9 million in 2006. The 2007 increase was primarily attributable to increases in premises and equipment due to the addition of three new branches and administrative facilities during 2007, increases in accrued interest receivable on a higher earning asset balance and three new low income housing tax credit projects that funded during 2007. The 2006 increase of $20.9 million was primarily attributable to increases in cash and due from banks, premises and equipment due to the addition of new branches during 2006 and accrued interest receivable on a higher earning asset balance.

ALLOWANCE FOR LOAN LOSSES

The balance in the allowance for loan losses increased slightly to $34.3 million or 1.23 percent of total loans at December 31, 2007 as compared to $33.2 million or 1.25 percent of total loans at December 31, 2006. The allowance for loan losses is consistent with the growth in commercial loans, lower 2007 charge-off levels and lower specific reserves established during 2007. The allowance for lending-related commitments is computed using a methodology similar to that used to determine the allowance for loan losses. Amounts are added to the allowance for lending-related commitments through a charge to current earnings through noninterest expense. The balance in the allowance for lending-related commitments decreased to $0.9 million at December 31, 2007 as compared to $1.2 million at December 31, 2006.

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. 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. Charged-off and recovered loan amounts are applied to the allowance for loan losses. Periodic updates are presented to the S&T Board of Directors as to the status of loan quality. Amounts are added to the allowance for loan losses 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 for probable loan losses. A quantitative analysis is utilized to support the adequacy of the allowance for loan losses. This analysis includes review of the historical charge-off rates for all loan categories, fluctuations and trends in various risk factors. Factors consider the level of S&T’s historical charge-offs that have occurred within segmented portfolios over the last 7 years. Management also assesses qualitative factors such as portfolio credit trends, unemployment trends, vacancy trends, loan growth and variable interest rate factors.

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 of the portfolio 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 2007, the risk rating profile of the portfolio was primarily impacted by three commercial loan relationships. The first commercial loan relationship is a construction servicing company totaling $1.8 million that filed for bankruptcy during the first quarter of 2007. During the third quarter of 2007, a $1.4 million charge-down was taken on this commercial relationship. The remaining balance of $0.2 million is believed to be adequately collateralized. The second loan relationship is a heavy construction company which was charged-down by $7.2 million during the third quarter of 2006. During the third quarter of 2007, an additional charge-down of $1.2 million was taken on this relationship related to a workers compensation letter of credit draw. In addition, a specific reserve of $2.1 million has been allocated to the relationship as a result of collateral shortfalls in recent equipment auctions. S&T is currently pursuing recovery through legal processes. This relationship has a remaining balance of $1.7 million, net of the $2.1 million specific reserve, and is believed to be adequately collateralized by equipment. The third commercial loan relationship totaling $0.9 million is with a construction company that filed for bankruptcy during the third quarter of 2007 and is no longer operating. A specific reserve of $0.9 million has been allocated to this commercial loan relationship. These three commercial relationships have been adequately reserved as determined by the quarterly impairment analysis and risk-rating process performed by the loan administration department. The remaining risk rating profile of the portfolio has shown overall improvement absent the aforementioned three commercial loan relationships.

The allowance for loan losses is established based on management’s assessment of the factors noted above along with the growth in the loan portfolio. The additions to the allowance charged to operating expense has maintained the allowance as a percent of loans at the following levels at the end of each year presented below:

2007	2006	2005	2004	2003
1.23%	1.25%	1.47%	1.50%	1.50%

We have considered impaired loans in our determination of the allowance for loan losses. The allowance for loan losses for all impaired loans was $2,919,000 and $2,627,000 at December 31, 2007 and 2006, respectively.

Net loan charge-offs totaled $4.7 million in 2007 and $12.7 million in 2006. The most significant charge-offs for 2007 were $1.6 million for a construction servicing company, an additional charge-off of $1.2 million related to a workers compensation letter of credit draw for a heavy construction company and a $0.9 million commercial loan relationship for a security distribution and installation company, all of which were previously considered in the analysis for the adequacy of the allowance for loan losses. Net loan charge-offs for 2006 were affected by three commercial loan relationships that comprised $11.4 million of the total net charge-offs for 2006. Two of those troubled credits have combined remaining loan balances of $5.5 million and are believed to be adequately collateralized.

The balance of nonaccrual loans past due 90 days or more, at December 31, 2007, was $16.8 million or 0.60 percent of total loans. This compares to nonaccrual loans of $19.9 million or 0.74 percent of total loans at December 31, 2006. Nonperforming assets totaled $17.3 million or 0.51 percent of total assets at December 31, 2007 as compared to $20.4 million or 0.61 percent at December 31, 2006. The most significant credits in nonperforming status at December 31, 2007 were $3.8 million commercial relationship that managed and rehabilitated residential rental properties, $3.7 million residual balance of a heavy construction company, $1.7 million residual balance mixed-use, commercial real estate loan participation with another financial institution and a $1.3 million residual balance related to a limestone mining company. Also affecting nonaccrual loans at December 31, 2007 is a $0.9 million loan relationship with a construction company that filed for bankruptcy in the fourth quarter of 2007.

The provision for loans losses was $5.8 million for 2007, as compared to $9.4 million for 2006. The provision was the result of management’s detailed analysis of the adequacy of the allowance for loan losses and is consistent with the significant decrease in charge-off rates and an improvement in nonaccrual loans compared to last year.

The following table summarizes our nonaccrual and past due loans:

	December 31
	2007		2006		2005		2004		2003

Accruing loans past due 90 days or more		—		—		—		—		—

It is S&T’s policy to place loans in all categories on nonaccrual status when collection of interest or principal is doubtful, or generally when interest or principal payments are 90 days or more past due. There are no loans 90 days or more past due and still accruing. For the year ended December 31, 2007 and 2006, interest that would have been recorded had the nonaccrual loans performed in accordance with the original loan terms was $2,410,000 and $1,642,000, respectively. At December 31, 2007 and 2006, there was $6,356,000 and $8,617,000, respectively, of impaired loans that were on nonaccrual. There is no foreign loan amounts required to be included in this table. There were no troubled debt restructures in the periods presented.

DEPOSITS

Average total deposits increased by $90.6 million in 2007 and $261.6 million in 2006. The mix of average deposits changed in 2007 with average time deposits increasing $19.7 million and average savings accounts increasing $92.6 million. Partially offsetting these increases is a decrease of $39.9 million in average money market and NOW accounts. Average noninterest-bearing deposits increased by $18.2 million or 4 percent in 2007 and were approximately 17 percent of average total deposits during 2007 and 2006. The increase in savings accounts is primarily attributable to the success of the S&T Cash Management account, which had an outstanding balance of $811.6 million at December 31, 2007. The S&T Cash Management account was introduced in November 2006 to replace the Plan B high yield savings account. Both the accounts were non-indexed but the S&T Cash Management account added the feature of tiering, or the payment of higher rates on higher balances. The S&T Cash Management account pricing feature is expected to allow S&T to continue core deposit growth that better compliments shifting interest rate sensitivity. Core deposit growth has been an important strategic initiative for S&T, through the expansion of retail facilities, promotions and new products. Other important strategies include providing cash management services to commercial customers to increase transaction related deposits, and delivery services such as electronic banking. Total deposits at December 31, 2007 increased $56.5 million compared to December 31, 2006.

The daily average amount of deposits and rates paid on such deposits is summarized for the periods indicated in the following table:

	Year Ended December 31
	2007				2006				2005
	Amount		Rate		Amount		Rate		Amount		Rate

Maturities of time certificates of deposit of $100,000 or more outstanding at December 31, are summarized as follows:

(dollars in thousands)	2007
Three months or less	$	98,167
Over three through six months		71,161
Over six through twelve months		47,978
Over twelve months		32,337
TOTAL	$	249,643

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. Time certificates of deposit of $100,000 and over were 10 percent of total deposits at December 31, 2007 and 2006, and primarily represent deposit relationships with local customers in our market area. In addition, management believes that S&T has the ability to access both public and private markets to raise long-term funding if necessary. S&T had $2.8 million of brokered retail certificates of deposit outstanding at December 31, 2007 and December 31, 2006. The purchase of brokered retail certificates of deposits in 2007 and 2006 was an ALCO strategy to increase liquidity for commercial loan demand, as an alternative to increased borrowings.

BORROWINGS

Average borrowings by S&T decreased $12.6 million in 2007 as a result of maturing investment securities not being replaced and deposit growth. Borrowings were comprised of retail repurchase agreements (“REPOs”), wholesale REPOs, federal funds purchased, FHLB advances and long-term borrowings. S&T defines REPOs with our retail customers as retail REPOs; wholesale REPOs are those transacted with other banks and brokerage firms.

The average balance in retail REPOs increased by $9.3 million in 2007 and $1.5 million in 2006. S&T views retail REPOs as a relatively stable source of funds because most of these accounts are with local, long-term customers.

21

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

Wholesale REPOs, federal funds purchased and FHLB advances averaged $68.5 million in 2007, a decrease of $71.8 million from the 2006 averages. The decrease is attributable to the increase in deposits, maturing investment securities and a strategy to utilize longer-term borrowings in 2007.

During 2007, average long-term borrowings increased $75.1 million as compared to December 31, 2006. At December 31, 2007, S&T had long-term borrowings outstanding of $147.9 million at a fixed-rate and $3.1 million at a variable rate with the FHLB. The increase in long-term borrowings is part of an ALCO strategy to limit interest rate risk as customer preferences have shifted to short-term and variable rate deposits, and to take advantage of lower cost funds through the FHLB’s Community Investment Program.

During the third quarter of 2006, S&T Bank issued $25.0 million of junior subordinated debentures through a pooled transaction at an initial fixed rate of 6.78 percent. On September 15, 2011, and quarterly thereafter, S&T Bank has the option to redeem the subordinated debt, subject to a 30 day written notice and prior approval by the FDIC. If S&T Bank chooses not to exercise the option for early redemption on September 15, 2011 or subsequent quarters, the subordinated debt will convert to a variable rate of 3-month LIBOR plus 160 basis points. The subordinated debt qualifies as Tier 2 capital under regulatory guidelines and will mature on December 15, 2036.

The following table shows the distribution of our short-term borrowings and the weighted average interest rates thereon at the end of each of the last three years. Also provided are the maximum amount of borrowings and the average amounts of borrowings as well as weighted average interest rates for the last three years.

WEALTH MANAGEMENT ASSETS

The year-end 2007 market value balance of the S&T Bank wealth management assets under management, which are not accounted for as part of the assets of S&T, decreased 5 percent in 2007 to $1.3 billion, with $916.5 million in wealth management services and $385.7 million in brokerage services. S&T experienced a high level of attrition in wealth management assets in 2007 due to loss of accounts with the conversion to a new broker-dealer; loss of a large institutional account, and; the death of a large individual investor for whom S&T was the guardian.

EXPLANATION OF USE OF NON-GAAP FINANCIAL MEASURES

In addition to the results of operations presented in accordance with generally accepted accounting principles (“GAAP”), S&T management uses, and this annual report contains or references, certain non-GAAP financial measures, such as net interest income on a fully tax-equivalent basis and operating revenue. S&T believes these non-GAAP financial measures provide information useful to investors in understanding our underlying operational performance and our business and performance trends as they facilitate comparisons with the performance of others in the financial services industry. Although S&T believes that these non-GAAP financial measures enhance investors’ understanding of S&T’s business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP.

We believe the presentation of net interest income on a fully 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 24.

22

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

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 business and operating results, S&T management believes it is appropriate to evaluate the significance of net interest income as a component of operating revenue.

RESULTS OF OPERATIONS

Year Ended December 31, 2007

NET INCOME

Net income was $56.1 million in 2007, a 5 percent increase from the $53.3 million in 2006. Earnings per share increased 10% from $2.06 diluted earnings per share in 2006 to $2.26 diluted earnings per share in 2007. Earnings per share percentage increases were higher than net income percentage increases due to a successful stock buyback program in 2007. The increase in net income was primarily the result of increases in net interest income, a significantly lower loan loss provision and an increase in other noninterest income, offset by lower security gains and an increase in noninterest expense. The return on average assets was 1.68 percent for 2007, as compared to 1.64 percent for 2006. The return on average equity was 16.97 percent for 2007 compared to 15.37 percent for 2006.

RETURN ON EQUITY AND ASSETS

The table below shows consolidated operating and capital ratios of S&T for each of the last three years:

	Year Ended December 31
	2007		2006		2005
Return on average assets	1.68	%	1.64	%	1.90	%
Return on average equity	16.97	%	15.37	%	16.57	%
Dividend payout ratio	53.06	%	56.34	%	50.38	%
Equity to asset ratio	9.87	%	10.16	%	11.03	%

NET INTEREST INCOME

Net interest income represents the difference between the interest and fees earned on interest-earning assets and the interest paid on interest-bearing liabilities. Net interest income is affected by changes in the volume of interest-earning assets and interest-bearing liabilities and changes in interest yields and rates. Therefore, maintaining consistent spreads between earning assets and interest-bearing liabilities is very significant to our financial performance because net interest income comprised 76 percent of operating revenue (net interest income plus noninterest income, excluding security gains) in 2007 and in 2006. 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.

On a fully tax-equivalent basis, net interest income increased $3.5 million or 3 percent in 2007 compared to 2006. Net interest income increases in 2007 are primarily attributable to growth in earning assets, primarily loans. The net yield on interest earning assets increased slightly to 3.87 percent in 2007 as compared to 3.86 percent in 2006. This consistency in the net yields on earning assets is primarily the result of effective asset liability strategies in a sometimes volatile interest rate environment. S&T’s balance sheet at December 31, 2007 is slightly liability sensitive, with funding costs decreasing faster than asset yields in a declining interest rate environment.

In 2007, average loans increased $143.6 million and average securities, other investments and federal funds sold decreased $65.8 million. The yields on average loans increased by 14 basis points, and the yields on average securities slightly decreased by 1 basis point. Overall earning asset yields increased 19 basis points.

Average interest-bearing deposits provided $72.4 million of the funds for the growth in average earning assets, at a cost of 3.70 percent in 2007 as compared to 3.54 percent in 2006. The cost of repurchase agreements and other borrowed funds increased 24 basis points to 5.20 percent. Overall funding costs increased 17 basis points.

23

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

Negatively affecting net interest income was a $7.1 million decrease in average net free funds during 2007 compared to 2006. Average net free funds are the excess of demand deposits, other noninterest-bearing liabilities and shareholders’ equity over nonearning assets. The decrease is primarily due to a successful stock buy-back program in 2007, defined benefit pension plan fundings and an increase in premises and equipment due to new branches and administrative facilities during 2007.

Interest on loans to and obligations of state, municipalities and other public entities are not subject to federal income tax. As such, the stated (pre-tax) yield on these assets is lower than the yields on taxable assets of similar risk and maturity. In order to make the pre-tax income and resultant yields comparable to taxable loans and investments, a tax-equivalent adjustment was added to interest income in the tables below. This adjustment is calculated using the U.S. federal statutory corporate income tax rate of 35 percent for 2007, 2006 and 2005.

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 is an amount added to the allowance against which loan losses are charged. The provision for loan losses was $5.8 million and $9.4 million for 2007 and 2006, respectively. The provision is the result of management’s assessment of credit quality statistics and other risk factors that would have an impact on probable losses in the loan portfolio, and the model used to determine the adequacy of the allowance for loan losses. A statistical model is used to assist in the determination of the adequacy of the allowance for loan losses. Changes in the risk ratings within the allowance for loan loss model are consistent with an improvement in asset quality, which includes a significant decrease in net loan charge-offs and nonaccrual loans.

Credit quality is the most important factor in determining the amount of the allowance, and the resulting provision. Also affecting the amount of the allowance and resulting provision is loan growth and portfolio composition. Most of the loan growth in 2007 and 2006 is attributable to larger commercial loans. Net loan charge-offs totaled $4.7 million for 2007 and $12.7 million in 2006. The most significant charge-offs for 2007 were $1.4 million for a construction servicing company, an additional charge-off of $1.2 million related to a workers compensation letter of credit draw for a heavy construction company and a $0.8 million commercial loan relationship for a security distribution and installation company, all of which were previously considered in the analysis for the adequacy of the allowance for loan losses. The most significant charge-offs for 2006 were $7.2 million for a heavy construction company, $2.7 million for a commercial real estate participation loan and $1.5 million for a food distributor, all of which were previously considered in the analysis for the adequacy of the allowance for loan losses. Nonaccrual loans to total loans decreased to 0.60 percent at December 31, 2007 as compared to 0.74 percent at December 31, 2006.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

NONINTEREST INCOME

Noninterest income, excluding net security gains, increased $1.9 million, or 5 percent in 2007 compared to 2006. Increases included $0.6 million or 10 percent in insurance activities, and $2.2 million or 32 percent in other noninterest income. Offsetting these increases were decreases of $0.4 million or 5 percent in wealth management fees, 0.3 million or 12 percent in letter of credit fees and $0.3 million or 3 percent in service charges and fees on deposit accounts.

Insurance commissions increased $0.6 million or 10 percent primarily as a result of stronger overall sales volume. This area was the focus of several strategic initiatives and product enhancements implemented in order to expand this source of noninterest income. The $2.2 million or 32 percent increase in other noninterest income is primarily due to a reclassification of investment securities held in the deferred compensation plan trust to a trading classification, within other assets, from an available for sale classification. The reclassification generated a one-time favorable adjustment to other noninterest income of $1.2 million in the third quarter of 2007. This change is consistent with the guidance in Emerging Issues Task Force (“EITF”) No. 97-14, “Accounting for Deferred Compensation Arrangements Where Amounts Earned Are Held in a Rabbi Trust and Invested,” and will eliminate future income statement volatility related to the accounting of the deferred compensation plan. Other increases to other noninterest income were $0.8 million for merchant and debit card revenue. The $0.4 million or 5 percent decrease in wealth management fees is primarily related to a $0.4 million accrual adjustment in 2006. Other decreases include $0.3 million or 12 percent in letter of credit fees due to lower customer demand for this product and $0.3 million or 3 percent decrease in service charges on deposit accounts primarily the result of a strategic decision to offer free internet banking with bill payment to our customers, and lower NSF fees due to customer behavior patterns.

S&T recognized $3.8 million of gains on the sale of available for sale securities in 2007. These gains were partially offset by $0.1 million of realized losses taken for an-other-than-temporary impairment, in accordance with FSP 115-1 and FAS 124-1, “The Meaning of Other-Than-Temporary Impairment and Its Application to Certain Investments”, on three equity investment securities. Security gains were primarily attributable to the sales of equity securities in order to maximize returns by taking advantage of market opportunities when presented. The equities portfolio is comprised primarily of bank holding company common stock.

NONINTEREST EXPENSE

Noninterest expense increased $4.2 million or 6 percent in 2007 compared to 2006. S&T’s efficiency ratio, which measures noninterest expense as a percent of noninterest income, excluding security gains plus net interest income on a fully tax-equivalent basis, was 47 percent in 2007 and 45 percent in 2006.

Staff expense increased 7 percent or $2.8 million in 2007. This increase is primarily attributable to a $1.2 million increase in base salaries due to year-end merit increases, an increase of $2.0 million in incentive plan accruals based on 2007 award levels, an increase of $0.5 million in medical expense, offset by a $0.9 million decrease in pension and deferred compensation plan expense. The majority of S&T incentive plan awards are based upon growth in earnings per share.

S&T’s net periodic defined benefit plan cost is based primarily on three assumptions: the discount rate for plan liabilities, the expected return on plan assets and the rate of compensation increase. Net periodic pension expense of $0.1 million and $0.8 million, respectively was recorded for S&T’s defined benefit plan for 2007 and 2006. Net periodic pension expense (income) is expected to approximate $(0.1) million for the year 2008, assuming no significant changes in plan assumptions.

Occupancy and equipment expense increased 14 percent or $1.2 million as compared to 2006 due to several facility restructurings, which included the closing of four branches, the addition of three new branches and expanded operational and administrative facilities. During the fourth quarter of 2007, S&T established an accrual of $0.3 million, included in other expenses, for our proportionate share of the potential liability related to litigation matters of Visa U.S.A.

FEDERAL INCOME TAXES

Federal income tax expense increased $0.1 million to $21.6 million in 2007 as compared to 2006. This increase is primarily attributable to an increase in pre-tax income, offset by an increase in Federal Historic Tax Credit projects during 2007. The effective tax rate of 28 percent in 2007 and 29 percent in 2006 was below the 35 percent statutory tax rate due to the tax benefits resulting from tax-exempt interest, excludable dividend income and the tax benefits associated with Low Income Housing Tax Credit (“LIHTC”) and Federal Historic Tax Credit projects. S&T currently does not incur any alternative minimum tax.

RESULTS OF OPERATIONS

Year Ended December 31, 2006

NET INCOME

Net income was $53.3 million or $2.06 per diluted earnings per share in 2006, an 8 percent decrease from the $58.2 million or $2.18 per diluted earnings per share in 2005. The decrease in earnings was primarily the result of a higher provision for loan losses due to the deterioration in the credit quality of three large commercial loan relationships, the $0.9 million charge-down for properties previously acquired through foreclosure and other increases to noninterest expense. The return on average assets was 1.64 percent for 2006, as compared to 1.90 percent for 2005. The return on average equity at 15.37 percent for 2006 compared to 16.57 percent for 2005.

NET INTEREST INCOME

On a fully tax-equivalent basis, net interest income increased $1.0 million or 1 percent in 2006 compared to 2005. The net yield on interest-earning assets decreased to 3.86 percent in 2006 as compared to 4.05 percent in 2005. The decrease in net yield on interest earning assets is primarily attributable to the effect of higher short-term interest rates in combination with a flat and inverted yield curve during the period. S&T’s balance sheet is liability sensitive, with funding costs rising faster than asset yields in the interest rate environment.

In 2006, average loans increased $217.3 million and average securities, other investments and federal funds sold decreased $50.7 million. The yields on average loans increased by 80 basis points and the yields on average securities increased 15 basis points. Overall earning asset yields costs increased 75 basis points.

Average interest-bearing deposits provided $249.1 million of the funds for the growth in average earning assets, at a cost of 3.54 percent in 2006 as compared to 2.45 percent in 2005. The cost of repurchase agreements and other borrowed funds increased 157 basis points to 4.96 percent. Overall funding costs increased 112 basis points.

Negatively affecting net interest income was a $13.8 million decrease in average net free funds during 2006 compared to 2005. Average net free funds are the excess of demand deposits, other noninterest-bearing liabilities and shareholders’ equity over nonearning assets. The decrease is primarily due to the successful stock buy-back program in 2006, higher levels of cash and due from banks, defined benefit pension plan fundings and an increase in premises and equipment due to new branches and administrative facilities during 2006.

PROVISION FOR LOAN LOSSES

The provision for loan losses was $9.4 million and $5.0 million for 2006 and 2005, respectively. Most of the loan growth in 2006 and 2005 is attributable to larger commercial loans. Net loan charge-offs totaled $12.7 million for 2006 and $1.7 million in 2005. Included in the 2006 net charge-offs was a $7.2 million for a construction company, $2.7 million for a commercial real estate loan participation and $1.5 million for a wholesale distributor, all of which were previously considered in the analysis for the adequacy of the allowance for loan losses. Nonaccrual loans to total loans increased to 0.74 percent at December 31, 2006 as compared to 0.45 percent at December 31, 2005.

NONINTEREST INCOME

Noninterest income, excluding net security gains, increased $2.5 million or 8 percent in 2006 compared to 2005. Increases included $0.8 million or 9 percent in service charges on deposit accounts, a $0.9 million or 13 percent increase in wealth management fees, a $1.0 million or 17 percent increase in insurance activities and a $0.6 million or 8 percent in other revenues, offset by a $0.8 million or 53 percent decrease in mortgage banking activities.

S&T recognized $6.1 million of gross gains on securities and gross losses of $0.6 million on the sale of securities in 2006. Security gains were primarily attributable to the sales of equity securities in order to maximize returns by taking advantage of market opportunities when presented. The equities portfolio is comprised primarily of bank holding company common stock.

The increase in wealth management fees was a result of new business development and increased performance in the stock market values of customer accounts during 2006. Insurance commissions increased $1.0 million primarily as a result of stronger overall sales volume and the acquisition of Holsinger Insurance Agency during the first quarter of 2006. These areas were the focus of several strategic initiatives and product enhancements implemented in order to expand these sources of noninterest income. Other fee revenue increases of $0.6 million include increases of $0.5 million in debit/credit card activity.

28

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

NONINTEREST EXPENSE

Noninterest expense increased $6.8 million or 11 percent in 2006 compared to 2005. S&T’s efficiency ratio, which measures noninterest expense as a percent of noninterest income, excluding security gains plus net interest income on a fully tax-equivalent basis, was 45 percent in 2006 and 42 percent in 2005.

Staff expense increased 8 percent or $2.9 million in 2006. This increase is primarily attributable to the effects of year-end merit increases, increased staffing levels required to implement new initiatives and expanded retail facilities and the $0.8 million effect of implementing FASB Statement No. 123(R), “Share Based Payment”. Also impacting staff expense in 2006 was a $1.0 million incentive paid to all employees to provide transitioning from bank-wide stock option grants into a new performance-based incentive plan. No corporate-wide stock option grants, including grants to executive management and directors, were awarded in 2006, as compared to prior years. Average full-time equivalent staff was 801 in 2006 and 786 in 2005.

S&T’s net periodic defined benefit plan cost is based primarily on three assumptions: the discount rate for plan liabilities, the expected return on plan assets and the rate of compensation increase. Net periodic pension expense of $0.8 million and $0.9 million, respectively for S&T’s defined benefit plan for 2006 and 2005.

Occupancy, equipment and data processing expense increased 7 percent or $0.9 million as compared to 2005 due to several facility restructurings, which included the addition of new branches and administrative facilities. Other tax expense increased 10 percent or $0.3 million as compared to 2005 primarily as a result of increases in Pennsylvania shares tax. Other expenses increased 25 percent or $2.5 million in 2006 as compared to 2005 primarily due to a $1.0 million of write-downs of real estate previously acquired through foreclosure to current market values, an increase of $0.6 million in the allowance for lending-related commitments, a $0.3 million increase in legal expenses and $0.4 million of revenue received in 2005 for a historical rehabilitation tax credit partnership.

FEDERAL INCOME TAXES

Federal income tax expense decreased $2.8 million to $21.5 million in 2006 as compared to 2005. This decrease is primarily attributable to a decrease in pre-tax income. The effective tax rate of 29 percent in 2006 and 2005 was below the 35 percent statutory tax rate due to the tax benefits resulting from tax-exempt interest, excludable dividend income and the tax benefits associated with Low Income Housing Tax Credit (“LIHTC”) and Federal Historic Tax Credit projects. S&T currently does not incur any alternative minimum tax.

LIQUIDITY AND CAPITAL RESOURCES

Shareholders’ equity decreased $1.5 million at December 31, 2007 compared to December 31, 2006. The primary source of equity growth is earnings retention. Capital growth is a function of net income less dividends paid to shareholders and treasury stock activities.

Net income was $56.1 million and dividends declared to shareholders were $29.8 million for 2007. S&T paid 53 percent of 2007 net income in dividends, equating to an annual dividend rate of $1.21 per share. Also affecting capital was a decrease of $1.6 million in unrealized gains and is included in other comprehensive income.

During 2007, S&T repurchased 971,400 shares of its common stock at an average price of $32.74 per share. The impact of the repurchased shares is $0.03 increase to 2007 diluted earnings per share. The S&T Board of Directors previously authorized a stock buyback program for 2007 of up to one million shares, or approximately 4 percent of shares outstanding. On June 18, 2007, the S&T Board of Directors authorized a new stock buyback program until June 30, 2008 of an additional one million shares. S&T reissued 161,213 shares during 2007 primarily through the exercise of employee stock options. See schedule on page 13 for the 2007 share repurchase activity.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

On September 21, 2006, S&T Bank issued $25.0 million of junior subordinated debt through a pooled transaction at an initial fixed rate of 6.78%. On September 15, 2011 and quarterly thereafter, S&T bank shall have the option to redeem the subordinated debt, subject to a 30 day written notice and prior approval by the FDIC. If S&T Bank chooses not to exercise the option for early redemption on September 15, 2011 or subsequent quarters, the subordinated debt will convert to a variable rate of 3-month LIBOR plus 160 basis points. The subordinated debt qualifies as Tier 2 capital under regulatory guidelines and will mature on December 15, 2036.

S&T continues to maintain a strong capital position with a leverage ratio of 8.6 percent as compared to the 2007 minimum regulatory guideline of 3 percent. S&T’s risk-based capital Tier 1 and Total ratios were 9.5 percent and 11.6 percent, respectively, at December 31, 2007, which places S&T well above the Federal Reserve Board’s risk-based capital guidelines of 4 percent and 8 percent for Tier 1 and Total capital. Included in the total ratio are 45 percent of the pretax unrealized holding gains on available for sale equity securities as prescribed by banking regulations effective October 1, 1998. In addition, management believes that S&T has the ability to raise additional capital if necessary.

During 2003, 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 $150.0 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 December 31, 2007, S&T had not issued any securities pursuant to the shelf registration statement.

In April 1993, shareholders approved the S&T Incentive Stock Plan (“Stock Plan”) authorizing the issuance of a maximum of 1.2 million shares of S&T’s common stock to assist in attracting and retaining employees of outstanding ability and to align their interests with those of the shareholders of S&T. On October 17, 1994, the Stock Plan was amended to include outside directors. On April 21, 1997, shareholders approved an amendment to the Stock Plan increasing the number of authorized shares to 3.2 million. As of December 31, 2002, 3,180,822 nonstatutory stock options and 35,600 restricted stock awards had been granted to key employees and outside directors under the Stock Plan; 658,800 of these awards are currently exercisable. In April 2003, shareholders approved the 2003 S&T Incentive Stock Plan (“2003 Stock Plan”) authorizing the issuance of 1.5 million shares, subject to capital adjustments as provided in the 2003 Stock Plan. The purpose of the 2003 Stock Plan is to promote the long-term interests of S&T and its shareholders by attracting and retaining directors, officers and key employees. S&T believes that directors, officers and employees who own shares of its common stock will have a closer identification with S&T and a greater motivation to work for S&T’s success, because, as shareholders, they will participate in S&T’s growth and earnings. As of December 31, 2006, 937,500 nonstatutory stock options had been granted under the 2003 Stock Plan to employees and directors; 676,225 of these awards are currently exercisable. On December 19, 2005, S&T also granted 206,900 cash appreciation rights under the 2005 Cash Appreciation Rights (“CARs”) Plan to employees, with 47,538 of these awards currently exercisable. No corporate-wide stock option grants were awarded in 2006. On April 16, 2007, 7,761 restricted stock awards were granted to outside directors. On December 17, 2007, 35,199 restricted stock awards were granted to senior management. The awards to senior management were granted in accordance with 2007 performance levels and primarily based on earnings per share growth. The restricted stock awards have a vesting schedule of 25% in each of the next four years.

Operating lease obligations represent short-term lease arrangements as described in Note F to the consolidated financial statements. Purchase obligations represent obligations under agreement with Metavante, S&T’s third party data processing servicer, for operational services outsourced. The Metavante obligation has a buyout provision of 40 percent of the remaining payments under the original term of the contract.

In the normal course of business, S&T commits to extend credit and issue standby letters of credit. These obligations are not recorded in our 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 and are renewed on an annual basis. Our 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 $663,124,000 and $686,204,000 at December 31, 2007 and 2006, respectively. Unfunded other loan commitments totaled $187,173,000 and $157,863,000 at December 31, 2007 and 2006, respectively; and obligations under standby letters of credit totaled $184,589,000 and $220,494,000 at December 31, 2007 and 2006, respectively.

REGULATORY MATTERS

S&T and S&T Bank are subject to periodic examinations by the Pennsylvania Department of Banking (“PA DOB”), the Federal Deposit Insurance Corporation (“FDIC”) and the Federal Reserve Bank of Cleveland (“Federal Reserve”). During 2007, the PA DOB conducted a Safety and Soundness examination that included, but was not limited to, a review of S&T Bank’s capital adequacy, asset quality, board of director and management oversight, earnings, liquidity, sensitivity to market risk and compliance with the Bank Secrecy Act. In addition, the PA DOB conducted stand alone Trust Department and Information Technology examinations. No comments were received from the PA DOB that would have a material effect on S&T’s liquidity, capital resources, operations or its overall compliance with laws and regulations. S&T’s current capital position and results of regulatory examination allow it to pay the lowest possible rate for FDIC deposit insurance.

CRITICAL ACCOUNTING POLICIES AND JUDGMENTS

We have established various accounting policies that govern the application of accounting principles generally accepted in the United States in the preparation of its consolidated financial statements. The most significant of these policies are described in Note A—Accounting Policies. 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.

Securities

Securities are reported at fair market value adjusted for premiums and discounts which are recognized in interest income using the interest method over the period to maturity. Declines in market value of individual securities below their amortized cost, and that are other-than-temporary, will be written down to current market value and included in earnings as realized losses. Management systematically evaluates securities for other-than-temporary declines in market value on a quarterly basis. If the financial markets experience deterioration, additional charges to income could occur in future periods.

Allowance for Loan Losses

Determination of an adequate allowance for loan losses is inherently subjective, as it requires estimations of occurrence of future events as well as timing of such events.

The allowance for loan losses is increased by charges to income and decreased by charge-offs (net of recoveries). S&T’s periodic evaluation of the adequacy of the allowance for loan losses is determined by management through evaluation of the loss exposure on individual impaired, nonperforming, delinquent and high-dollar loans; review of risk conditions and business trends; historical loss experience, and; growth and composition of the loan portfolio, as well as other relevant factors.

A quantitative analysis is utilized to support the adequacy of the allowance for loan losses. This analysis includes review of the historical charge-offs that have occurrence within segmented portfolios over the last 7 years. Management also assesses qualitative factors such as portfolio credit trends, unemployment trends, vacancy trends, loan growth and variable interest rate factors.

Significant to this analysis is the shift in loan portfolio composition to an increased mix of commercial loans. These loans are generally larger in size, and, due to our continuing growth, many are unseasoned or new loan relationships. Management relies on its risk-rating process to monitor trends that may be occurring relative to commercial loans to assess potential weaknesses within the credit. Current risk factors and trends in risk ratings are considered in the determination and allocation of the allowance for loan losses. During 2007, the risk-rating profile of the portfolio remained relatively stable.

The allowance for loan losses at December 31, 2007 includes $31.3 million or 91 percent of the allowance allocated to commercial and industrial and commercial real estate loans. The ability for customers to repay commercial loans is more dependent upon the success of their business, continuing income and general economic conditions. Accordingly, the risk of loss is higher on such loans than on residential real estate loans, which generally incur lower losses in the event of foreclosure as the collateral value typically exceeds the loan amounts.

Goodwill and Other Intangible Assets

S&T has $2.5 million of core deposit and other intangible assets subject to amortization and $50.1 million in goodwill, which is not subject to periodic amortization. S&T determined the amount of identifiable intangible assets based upon an independent core deposit analysis and insurance contract analysis. An annual evaluation of identifiable intangible assets for impairment is performed by S&T. S&T concluded that the recorded value of identifiable intangible assets was not impaired as a result of the evaluation as of December 31, 2007.

Goodwill arising from business combinations represents the value attributable to unidentifiable intangible elements in the business acquired. S&T’s goodwill relates to value inherent in the banking business and the value is dependent upon S&T’s ability to provide quality, cost-effective services in the face of free competition from other market participants on a regional basis. This ability relies upon continuing investments in processing systems, the development of value-added service features and the ease of use of S&T’s services. As such, goodwill value is supported ultimately by revenue that is driven by the volume of business transacted. A decline in earnings as a result of a lack of growth or the inability to deliver cost-effective services over sustained periods can lead to impairment of goodwill, which could adversely impact earnings in future periods. An annual evaluation of goodwill for impairment is performed by S&T. The market value of S&T and the implied market value of goodwill at the respective reporting unit level are estimated using industry comparable information. S&T concluded that the recorded value of goodwill was not impaired as a result of the evaluation as of October 1, 2007.

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

Income Taxes

S&T estimates income tax expense based on amounts expected to be owed to the tax jurisdictions where S&T conducts business. On a quarterly basis, management assesses the reasonableness of its effective tax rate based upon its current estimate of the amount and components of net income, tax credits and the applicable statutory tax rates expected for the full year.

Deferred income tax assets and liabilities are determined using the asset and liability method and are reported in the Consolidated Balance Sheets. Under this method, the net deferred tax asset or liability is based on the tax effects of the differences between the book and tax basis of assets and liabilities and recognizes enacted changes in tax rate and laws. Deferred tax assets are recognized to the extent they exist and are subject to a valuation allowance based on management’s judgement that realization is more-likely-than-not.

Accrued taxes represent the net estimated amount due to taxing jurisdictions and are reported in other liabilities in the Consolidated Balance Sheets. S&T evaluates and assesses the relative risks and appropriate tax treatment of transactions and filing positions after considering statutes, regulations, judicial precedent and other information and maintains tax accruals consistent with its evaluation of these relative risks and merits. Changes to the estimate of accrued taxes occur periodically due to changes in tax rates, interpretations of tax laws, the status of examinations being conducted by taxing authorities and changes to statutory, judicial and regulatory guidance. These changes, when they occur, can affect deferred taxes and accrued taxes as well as the current period’s income tax expense and can be significant to the operating results of S&T.

Joint Ventures

S&T has 27 limited partnership investments in affordable housing and federal historic rehabilitation projects, for which it provides funding as a limited partner and receives tax credits, tax deductions for losses incurred by the projects and proceeds from property disposition based on its partnership share prescribed by each partnership agreement. At December 31, 2007 and 2006, S&T had recorded investments in other assets on its balance sheet of approximately $18.0 million and $15.7 million, respectively, associated with these investments. These investments are accounted for on the equity method and are periodically reviewed for impairment. The impairment test includes estimated tax credits and tax benefits of future losses as well as the estimated residual values from the sale of certain properties. Investments in partnerships for the purpose of rehabilitating historic structures are evaluated for impairment at the end of each reporting period and are recorded at their net realizable value. The impairment test includes estimated tax benefits of future losses as well as the estimated residual values from the sale of certain properties. S&T determined that it is not the primary beneficiary of these partnerships and does not consolidate them.

INFLATION

Management is aware of the significant effect inflation has on interest rates and can have on financial performance. S&T’s ability to cope with this is best determined by analyzing its capability to respond to changing interest rates and its ability to manage noninterest income and expense. S&T monitors its mix of interest-rate sensitive assets and liabilities through ALCO in order to reduce the impact of inflation on net interest income. Management also controls the effects of inflation by reviewing the prices of its products and services, by introducing new products and services and by controlling overhead expenses.

“SAFE HARBOR” STATEMENT UNDER THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

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

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

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

Future Factors include:

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

• 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;

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

• rapid technological developments and changes;

• the ability to continue to introduce competitive new products and services on a timely, cost-effective basis;

• the mix of products/services;

• containing costs and expenses;

• governmental and public policy changes, including environmental regulations;

• reliance on large customers;

• technological, implementation and cost/financial risks in large, multi-year contracts;

• the outcome of pending and future litigation and governmental proceedings;

• continued availability of financing;

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

• changes in the local economy in western-Pennsylvania area;

• managing our internal growth and acquisitions; and

• 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.

• A continuation of recent turbulence in significant portions of the global financial and real estate markets could impact our performance, both directly by affecting our revenues and the value of our assets and liabilities and indirectly by affecting the economy generally.

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

LIQUIDITY AND INTEREST RATE SENSITIVITY

Liquidity refers to the ability to satisfy the financial needs of depositors who want to withdraw funds, or of borrowers needing access to funds to meet their credit needs. Interest-rate sensitivity management seeks to avoid fluctuating net interest margins and to enhance net interest income through periods of changing interest rates. The ALCO is responsible for establishing and monitoring the liquidity and interest rate sensitivity guidelines, procedures and policies.

The principal sources of asset liquidity are cash and due from banks, interest-earning deposits with banks, federal funds and securities available for sale. At December 31, 2007, the total of such assets was approximately $433.7 million or 13 percent of consolidated assets. While much more difficult to quantify, liability liquidity is further enhanced by a stable core deposit base, access to credit lines at other financial institutions and S&T’s ability to renew maturing deposits. Certificates of deposit in denominations of $100,000 or more represented 10 percent of deposits at December 31, 2007 and were outstanding primarily to local customers. S&T’s ability to attract deposits and borrow funds depends primarily on continued rate competitiveness, profitability, capitalization and overall financial condition.

34

Item 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS - continued

Beyond the issue of having sufficient sources to fund unexpected credit demands or deposit withdrawals, liquidity management also is an important factor in monitoring and managing interest-rate sensitivity issues through ALCO. Through forecast and simulation models, ALCO is also able to project future funding needs and develop strategies for acquiring funds at a reasonable cost. ALCO uses a variety of measurements to monitor the liquidity position of S&T. These include liquidity gap, liquidity forecast, net loans and standby letters of credit to assets, net loans to deposits and net non-core funding dependence ratio.

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Because the assets and liabilities of S&T are primarily monetary in nature, the presentation and analysis of cash flows in formats prescribed by accounting principles generally accepted in the United States are less meaningful for managing bank liquidity than for non-financial companies. Funds are typically provided from current earnings, maturity and sales of securities available for sale, loan repayments, deposits and borrowings. The primary uses of funds include new loans, repayment of borrowings, the purchase of securities and dividends to shareholders. The level and mix of sources and uses of funds are constantly monitored and adjusted by ALCO in order to maintain credit, liquidity and interest-rate risks within prescribed policy guidelines while maximizing earnings.

ALCO monitors and manages interest-rate sensitivity through gap, rate shock and rate ramp analyses, economic value of equity (EVE) and simulations in order to avoid unacceptable earnings fluctuations due to interest rate changes. Interest rate sensitivity analyses are highly dependent on assumptions, which have been developed based upon past experience and the expected behavior of customers under various rate scenarios. 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 represents 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 gap analysis below incorporates a flat rate scenario, and the following significant assumptions:

Monthly loan prepayments above contractual requirements
3 year ARM—Commercial Real Estate	1.50	%
5 year ARM—Commercial Real Estate	1.75	%
Fixed Rate—Commercial Real Estate	1.75	%
Residential Real Estate	1.59	%
Fixed Rate Home Equity	1.93	%
Other Installment Loans	2.50	%
Deposit behavioral pattern/decay rate assumptions
NOW and Regular Savings—Year #1	25.00	%
NOW and Regular Savings—Year #2	25.00	%
NOW and Regular Savings—beyond Year #2	50.00	%
Indexed, IRA Savings and Clubs – Month 1	100.00	%
Cash Management Savings and Money Market 1-6 Months	100.00	%
S&T has not historically experienced significant fluctuations in demand deposit balances during periods of interest rate fluctuations.	NA

Cumulative 6 months	0.78	0.86
Cumulative 12 months	0.81	0.87

S&T’s one-year gap position at December 31, 2007 indicates a liability sensitive position. This means that more liabilities than assets will reprice during the measured time frames. The implications of a liability sensitive position will differ depending upon the change in market interest rates. For example, with a liability sensitive position in a declining interest rate environment, more liabilities than assets will decrease in rate. This situation could result in an increase to our interest rate spreads, net interest income and operating spreads. Conversely, with a liability sensitive position in a rising interest rate environment, more liabilities than assets will increase in rates. This situation could result in a decrease to our interest rate spreads, net interest income and operating spreads.

S&T has become more liability sensitive since December 2006 mainly as a result of an inverted yield curve. An inverted yield curve occurs when short-term interest rates are higher than long-term interest rates. When the yield curve is inverted customers tend to prefer short-term deposits and long-term loans, both of which make the bank more liability sensitive.

In addition to the gap analysis, S&T performs rate shock and rate ramp analyses on a static balance sheet to estimate the effect that a +/- 100, +/-200 and +/-300 basis point instantaneous and gradual parallel shift in the yield curve would have on 12 months of pretax net interest income. The rate shocks incorporate assumptions regarding the level of interest rate changes on non-maturity deposit products (savings, money market, 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 and rate ramp analyses more useful than gap analysis alone. S&T’s policy is to limit the change in net interest income over a one-year horizon to –20% given changes in rates using shocks or rate ramps up to +/- 300 basis points. Although +/-100 and +/-200 basis point changes for the rate shock and rate ramp analyses are not policy guidelines, these analyses are performed to ensure directional consistency of the +/-300 basis point analysis. The December 2007 results reflect a 2.41% decrease and 3.62% decrease to net interest income in the –300 and +300 basis point rate shock analysis respectively.

36

Item 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK - continued

The table below shows the pretax net interest income impact of the +/-300 rate shock analyses.

Change in Pretax Net Interest Income	Immediate Change in Rates
(dollars in millions)	+300 bps			-300 bps
December 31, 2007	$	(4.4	)	$	(2.9	)
December 31, 2006	$	(6.8	)	$	0.0

The results in the –300 basis point shock scenario are not consistent with a liability sensitive gap position, which typically would indicate an increase in net interest income. This is primarily due to: (1) rates on regular savings, NOW and money market accounts are at low levels and cannot be decreased to any great extent as rates go down, and (2) loan refinance activity is assumed to be significant in rates down.

Comparing December 2007 to December 2006, the change in net interest income in the –300 basis point rate shock scenario declined. The decline is mainly due to the restructuring of the indexed Green Plan and Plan B savings products to the Cash Management Account. The Cash Management Account is a non-indexed savings product that is conservatively modeled to reflect that it may not fully capture a -300 basis point decrease in short term rates. Offsetting some of the decline is growth in fixed rate loans, repurchase agreement borrowings with floors, and short duration time deposits.

Consistent with a liability sensitive gap position, the +300 rate shock results show pretax net interest income decreasing in an increasing interest rate environment. When compared to December 2006 the restructuring of the S&T savings products had a positive impact on pretax net interest income, offset by growth in fixed rate loans and short duration time deposits.

In order to monitor interest rate risk beyond the one-year time horizon of shocks and rate ramps, S&T also performs economic value of equity (EVE) analysis. EVE represents the present value of all asset cash flows minus the present value of all liability cash flows. As with rate shock analysis, EVE incorporates management assumptions regarding prepayment behavior of fixed rate loans and securities with optionality and core deposit behavior. S&T’s policy is to limit the change in EVE to –35% given changes in rates up to +/-300 basis points. The December 2007 results reflect a 14.78% decrease and 6.40% decrease to EVE given a –300 and +300 basis point change in interest rates respectively.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

S&T Bancorp, Inc. and Subsidiaries

NOTE A

NATURE OF OPERATIONS

S&T Bancorp, Inc. (“S&T”) was incorporated on March 17, 1983 under the laws of the Commonwealth of Pennsylvania as a bank holding company and has two wholly owned subsidiaries, S&T Bank and 9th Street Holdings, Inc. S&T owns a one-half interest in Commonwealth Trust Credit Life Insurance Company (“CTCLIC”).

S&T is presently engaged in nonbanking activities through the following six entities: 9th Street Holdings, Inc., S&T Bancholdings, Inc., CTCLIC, S&T Insurance Group, LLC, S&T Professional Resources Group, LLC and Stewart Capital Advisors, LLC. 9th Street Holdings, Inc. was formed in June 1988 and S&T Bancholdings, Inc. was formed in August 2002 to hold and manage a group of investments previously owned by S&T Bank and to give S&T additional latitude to purchase other investments. CTCLIC, which is a joint venture with another financial institution, acts as a reinsurer of credit life, accident and health insurance policies sold by S&T Bank and the other institution. S&T Insurance Group, LLC distributes high-quality life insurance and long-term disability income insurance products through Evergreen Insurance Associates, LLC. S&T Professional Resources Group, LLC markets software developed by S&T Bank. Stewart Capital Advisors, LLC was formed in August 2005 to act as a registered investment advisor that manages private investment accounts for individuals and institutions and advises the Stewart Capital Mutual Fund.

ACCOUNTING POLICIES

The financial statements of S&T Bancorp, Inc. and subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America. In preparing the financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the balance sheets and revenues and expenses for the periods then ended. Actual results could differ from those estimates. The more significant accounting policies are described below.

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of S&T and its wholly owned subsidiaries. All significant intercompany transactions have been eliminated in consolidation. Investments of 20 percent—50 percent of the outstanding common stock of investees are accounted for using the equity method of accounting. S&T operates within one business segment, community banking, providing a full range of services to individual and corporate customers.

CASH FLOW INFORMATION

S&T considers cash and due from banks as cash and cash equivalents. For the years ended December 31, 2007, 2006 and 2005, interest paid was $99,370,000, $92,006,000 and $61,213,000, respectively. Income taxes paid during 2007 were $20,186,000 compared to $22,143,000 for 2006 and $23,153,000 for 2005. For the years ended December 31, 2007, 2006 and 2005, transfers of loans to other real estate owned was $488,000, $523,000 and $3,455,000, respectively.

SECURITIES

Management determines the appropriate classification of securities at the time of purchase. If management has the intent and S&T has the ability, at the time of purchase, to hold securities until maturity, they are classified as held to maturity and are stated at cost and adjusted for amortization of premiums and accretion of discounts. Securities that management does not have the intent and ability to hold to maturity are classified as available for sale and are recorded at market value, and unrealized gains and losses on these securities, net of related deferred income taxes, are reported in accumulated other comprehensive income. Gains or losses on the disposition of securities are based on the specific identification method. S&T does not engage in any securities trading activity for its own account.

Management systematically evaluates securities for other-than-temporary declines in market value. Securities for which declines in market value are deemed to be other-than-temporary are written down to current market value and the resultant changes included in earnings as realized losses.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

LOANS

Interest on loans is accrued and credited to operations based on the principal amount outstanding. Accretion of discounts and amortization of premiums on loans are included in interest income. Loan origination fees and direct loan origination costs are deferred and amortized as an adjustment of loan yield over the respective lives of the loans. Loans are placed on nonaccrual and interest is discontinued generally when interest and principal are 90 days or more past due.

Impaired loans are defined by management as commercial and commercial real estate loans which it is probable that S&T will not be able to collect all amounts due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status and underlying collateral value. All impaired loans are classified as substandard for risk classification purposes. Impaired loans are reserved, to the estimated value of collateral and/or cash flow associated with the loan, when management believes principal and interest will not be collected under the contractual terms of the loan. When interest accrual is discontinued, all unpaid accrued interest is reversed against interest income. Interest income is subsequently recognized only to the extent that cash payments are received.

The allowance for loan losses is established through provisions for loan losses charged against income. Loans considered to be uncollectible are charged against the allowance, and recoveries, if any, are credited to the allowance. The adequacy of the allowance for loan losses is determined by management through evaluation of the loss exposure on individual nonperforming, delinquent and high-dollar loans; review of various risk conditions and business trends; historical loss experience; and growth and composition of the loan portfolio, as well as other relevant risk factors.

A quantitative analysis is utilized to support the adequacy of the allowance for loan losses. This analysis includes review of the historical charge-off rates for loan categories, fluctuations and trends in the amount of classified loans and other risk factors. Factors consider the level of S&T’s historical charge-offs that have occurrence within segmented portfolios over the last 7 years. Management also assesses subjective factors such as portfolio credit trends, unemployment trends, vacancy trends, loan growth and variable interest rate factors.

Significant to this analysis is the shift in loan portfolio composition to an increased mix of commercial loans. These loans are generally larger in size, and due to our continuing growth, many are new loan relationships. Management relies on its risk-rating process to monitor trends that may be occurring relative to commercial loans to assess potential weaknesses within the credit. Current factors and trends in risk ratings are considered in the determination and allocation of the allowance for loan losses.

S&T believes its quantitative and qualitative analysis and risk-rating process, which serves as the primary basis for assessing the adequacy of the allowance for loan losses, is sufficient to allow it to conclude that the total allowance for loan losses is adequate to absorb probable loan losses.

LOANS ORIGINATED FOR SALE AND HELD FOR SALE

Loans held for sale consists of 1-4 family residential loans originated for sale in the secondary market and carried at lower of cost or market, determined on an aggregate basis. Loans held for sale were $0.9 million and $0.8 million at December 31, 2007 and 2006, respectively. Gains and losses on sales of loans held for sale are included in other income in the consolidated statements of income. S&T manages its exposure to changes in the market value of loans from the date of commitment to the borrower and the loan’s ultimate sale by entering into mandatory forward commitments to sell the loans. The extent to which S&T elects to cover its loan production with forward commitments varies based upon factors deemed by management to be appropriate in the circumstances. The market value related to the risk of the commitment is the hedged asset or liability on the balance sheet with a corresponding offset recorded in the income statement. The adjustment to the hedged asset or liability is included in the basis of the hedged item, while the market value of the derivative is recorded as a freestanding asset or liability. S&T does not use hedge accounting for these transactions.

PREMISES AND EQUIPMENT

Premises and equipment are stated at cost less accumulated depreciation. Maintenance and repairs are charged to expense as incurred, while improvements that extend an asset’s useful life are capitalized and depreciated over the estimated remaining life of the asset. Depreciation expense is computed generally by the straight-line method for financial reporting purposes and accelerated methods for income tax purposes. Useful lives range from three to 25 years for furniture and equipment; ten to 50 years for premises and two to 36 years for leasehold improvements. Leasehold improvements are amortized over the shorter of the asset’s useful life or the remaining lease term, including renewal periods when reasonably assured.

44

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

JOINT VENTURES

S&T has 27 limited partnership investments in affordable housing and federal historic rehabilitation projects, for which it provides funding as a limited partner and receives tax credits, tax deductions for losses incurred by the projects and proceeds from property disposition based on its partnership share prescribed by each partnership agreement. At December 31, 2007 and 2006, S&T had recorded investments in other assets on its balance sheet of approximately $18.0 million and $15.7 million, respectively, associated with these investments. These investments are accounted for on the equity method and are periodically reviewed for impairment. The impairment test includes estimated tax credits and tax benefits of future losses as well as the estimated residual values from the sale of certain properties. Investments in partnerships for the purpose of rehabilitating historic structures are evaluated for impairment at the end of each reporting period and are recorded at their net realizable value. The impairment test includes estimated tax benefits of future losses as well as the estimated residual values from the sale of certain properties. S&T determined that it is not the primary beneficiary of these partnerships and does not consolidate them.

OTHER REAL ESTATE

Other real estate is included in other assets and is comprised of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of a foreclosure. These properties are carried at the lower of cost or market value less estimated cost of resale. Loan losses arising from the acquisition of such property initially are charged against the allowance for loan losses. Gains or losses realized subsequent to acquisition are recorded in other expenses in the results of operations.

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill represents the excess of the purchase price over the fair value of net assets purchased. Goodwill is not amortized, but is evaluated for impairment annually. In 2007, 2006 and 2005, S&T performed the required impairment tests of goodwill at the respective reporting unit level and no impairment existed as of the valuation date, as the market value of S&T’s net assets exceeded their carrying value. If, for any future period, S&T determines that there has been impairment in the carrying value of its goodwill balances, S&T will record a charge to earnings, which could have a material adverse effect on S&T’s net income.

Intangible assets consist of $3.8 million for the acquisition of core savings deposits and $1.5 million in cost for the acquisition of insurance contract relationships and are amortized over their estimated weighted average lives of 11 years. The estimated aggregate amortization expense for each of the five succeeding years will approximate $0.5 million.

MORTGAGE LOAN SERVICING

Mortgage servicing assets are recognized as separate assets when servicing rights are acquired through loan originations when the underlying loan is sold. Upon sale, the mortgage servicing right is established, which represents the then current market value of future net cash flows expected to be realized for performing the servicing activities. The market value of the mortgage servicing rights 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 mortgage servicing rights. Increases in mortgage loan prepayments reduce estimated future net servicing cash flows because the life of the underlying loan is reduced. In determining the market value of

45

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

the mortgage servicing rights, mortgage interest rates, which are used to determine prepayment rates and discount rates, are held constant over the estimated life of the portfolio. Capitalized mortgage servicing rights are reported in other assets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying mortgage loans.

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

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

For the year ended December 31, 2007 and 2006, the 1-4 family mortgage loans that were sold to Fannie Mae amounted to $17.4 million and $18.8 million, respectively. At December 31, 2007 and 2006, mortgage servicing rights were $2.0 million and $2.1 million, respectively. At December 31, 2007, 2006 and 2005, S&T’s servicing portfolio totaled $178.9 million, $180.8 million and $185.1 million, respectively. The fair market value of mortgage servicing rights was $1.9 million and $2.1 million at December 31, 2007 and 2006, respectively.

DERIVATIVE FINANCIAL INSTRUMENTS

S&T utilizes derivative instruments from time to time for asset/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.

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 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. Because S&T acts as an intermediary for its customer, changes in the market value of the underlying derivative contracts offset each other and do not impact S&T’s results of operations.

S&T offers 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

46

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

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. 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.

WEALTH MANAGEMENT ASSETS AND INCOME

Assets held in a fiduciary capacity by the subsidiary bank, S&T Bank, are not assets of S&T Bank and are therefore not included in the consolidated financial statements. Wealth management fee income is reported on the consolidated statement of income on the accrual basis.

STOCK-BASED COMPENSATION

S&T has various stock-based employee compensation plans, which are described in Note O. S&T adopted FASB Statement of Financial Accounting Standard (“SFAS”) No. 123(R), “Share Based Payment,” on January 1, 2006 and is applying the modified prospective method. SFAS No. 123(R) requires measurement of compensation expense of all stock-based awards at fair value on the date of grant and recognition of compensation expense over the vesting period for all awards granted or not yet vested at the date of adoption. Prior to the adoption of SFAS No. 123(R), S&T applied APB Opinion No. 25, “Accounting for Stock Issued to Employees,” in accounting for stock-based awards.

The following table illustrates the effect on net income and earnings per share if SFAS 123(R) had been applied to all outstanding and unvested awards in 2005.

PENSIONS

Pension expense for S&T Bank’s defined benefit pension plan is actuarially determined using the projected unit credit actuarial cost method. The funding policy for the plan is to contribute amounts to the plan sufficient to meet the minimum funding requirements of the Employee Retirement Income Security Act of 1974, plus such additional amounts as may be appropriate, subject to federal income tax limitation.

On December 31, 2006, S&T adopted the recognition and disclosure provisions of Statement of Financial Accounting Standards (“SFAS”) No. 158. SFAS No. 158 requires an employer to recognize the funded status of any defined benefit pension plan or postretirement benefit plan in the December 31, 2006 statement of financial position, with a corresponding adjustment to accumulated other comprehensive income, net of tax. For the Plan, the adjustment to accumulated other comprehensive income at adoption represents the net unrecognized actuarial loss and unamortized prior service cost which were previously netted against the plan’s funded status in S&T’s statement of financial position pursuant to the provisions of SFAS No. 87. These amounts will be subsequently recognized as net periodic pension cost pursuant to S&T’s historical accounting policy for amortizing such amounts. Further, actuarial gains and losses that arise in subsequent periods and are not recognized as net periodic pension cost in the same periods will be recognized as a component of other comprehensive income. Those amounts will be subsequently recognized as a component of net periodic pension cost on the same basis as the amounts recognized in accumulated other comprehensive income upon adoption of SFAS No. 158.

INCOME TAXES

Deferred taxes are accounted for under the asset and liability method whereby deferred income taxes are recognized for the difference between the financial reporting and tax bases of assets and liabilities using enacted tax laws and rates. S&T files a consolidated income tax return. A deferred tax valuation allowance is established if it is more likely than not that all or a portion of the deferred tax assets will not be realized.

TREASURY STOCK

The purchase of S&T common stock is recorded at cost. At the time of reissuance, the treasury stock account is reduced using the average cost method.

EARNINGS PER COMMON SHARE

Basic Earnings Per Share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Average shares outstanding for computing basic EPS were 24,732,430, 25,735,295 and 26,384,062 for 2007, 2006 and 2005, respectively. Potentially dilutive securities are excluded from the basic calculation, but are included in diluted EPS. Average shares outstanding for computing diluted EPS were 24,888,574, 25,940,352 and 26,688,148 for 2007, 2006 and 2005, respectively. In computing diluted EPS, average shares outstanding have been increased by the common stock equivalents relating to S&T’s outstanding stock options and restricted stock.

ACQUISITION

On December 17, 2007, S&T announced that it would acquire IBT Bancorp, Inc., of Irwin, Pennsylvania (“IBT”), in a stock and cash transaction valued at approximately $171 million as of that date. The transaction is an in-market transaction that will expand S&T’s existing footprint in the Westmoreland and Allegheny counties of Pennsylvania. The combined company will have over $4.1 billion in assets and increase its market share from 5 percent to approximately 12 percent in Westmoreland County. IBT shareholders will receive either $31.00 cash or between 0.93 and 0.97 of a fraction of a share of S&T common stock for each of their shares of IBT common stock, with the precise fraction of a share based upon the average high and low sale price for S&T common stock for a twenty trading day period preceding the date of the meeting of IBT shareholders at which the merger will be considered.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS

In February 2006, FASB issued SFAS No. 155, “Accounting for Certain Hybrid Financial Instruments.” Under current generally accepted accounting principles, an entity that holds a financial instrument with an embedded derivative must bifurcate the financial instrument, resulting in the host and the embedded derivative being accounted for separately. SFAS No. 155 permits, but does not require, entities to account for certain financial instruments with an embedded derivative at fair value thereby eliminating the need to bifurcate the instrument into its host and the embedded derivative. SFAS No. 155 is effective for all financial instruments acquired or issued by S&T on or after January 1, 2007, and did not have a significant impact on S&T’s financial position or results of operations. During 2007, S&T had no new financial instruments acquired or issued after the date of adoption with embedded derivatives.

In March 2006, the FASB issued SFAS No. 156, “Accounting for Servicing of Financial Assets.” SFAS No. 156 amends SFAS No. 140, “Accounting for Transfers and Servicing of Financial Assets and Extinguishments of Liabilities,” with respect to the accounting for separately recognized servicing assets and servicing liabilities. SFAS No. 156 requires companies to recognize a servicing asset or servicing liability each time it undertakes an obligation to service a financial asset by entering into a servicing contract. SFAS No. 156 permits a company to choose either the amortized cost method or fair value measurement method for each class of separately recognized servicing assets. On January 1, 2007, S&T adopted the provisions of SFAS No. 156 using the amortized cost method for S&T’s mortgage servicing asset. The adoption of SFAS No. 156 did not have a significant impact on S&T’s financial position and results of operations.

In June 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,” an interpretation of SFAS No. 109, “Accounting for Income Taxes,” to create a single model to address accounting for uncertainty in tax positions. FIN 48 clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. S&T adopted FIN 48 as of January 1, 2007, as required. The cumulative effect of adopting FIN 48 decreased retained earnings by $150,666 which included $34,499 of interest. As permitted by FIN 48, S&T will continue to record interest and penalties as other income tax expense. There were no material changes to unrecognized tax benefits during 2007, and it is not anticipated that any such changes will occur by December 31, 2008. U. S. federal tax returns for tax years 2004 forward remain open to examination.

In September 2006, the FASB issued SFAS No. 157, “Fair Value Measurements.” SFAS No. 157 provides enhanced guidance for using fair value to measure assets and liabilities. SFAS No. 157 also responds to investors’ requests for expanded information about the extent to which companies measure 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 applies whenever other standards require (or permit) assets or liabilities to be measured at fair value. SFAS No. 157 does not expand the use of fair value in any new circumstances. S&T will be required to apply the new guidance effective January 1, 2008. S&T is in the process of determining the impact of applying SFAS No. 157 on S&T’s financial position and results of operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

In February 2007, the FASB issued SFAS No. 159, “The Fair Value Option for Financial Assets and Financial Liabilities,” which is effective as of the beginning of the entity’s first fiscal year that begins after November 15, 2007. SFAS No. 159 will enable entities to reduce the volatility in reported earnings caused by measuring related assets and liabilities differently. SFAS No. 159 is expected to expand the use of fair-value measurements and achieve a long-term objective of reporting all financial instruments at fair value. Early adoption is permitted as of the beginning of a fiscal year that begins on or before November 15, 2007, provided the entity also elects to apply the provisions of SFAS No. 157, “Fair Value Measurements.” S&T did not adopt SFAS No. 159 early and is in the process of determining the impact of adopting SFAS No. 159 on S&T’s financial position and results of operations.

In July 2007, the AICPA issued Statement of Position 07-1, Clarification of the Scope of the Audit and Accounting Guide for Investment Companies and Accounting by Parent Companies and Equity Method Investors for Investments in Investment Companies (“SOP 07-1”), which was expected to be effective for fiscal years beginning on or after December 15, 2007. However, the FASB has recently voted to delay the effective date indefinitely. SOP 07-1 sets forth more stringent criteria for qualifying as an investment company than does the predecessor Audit Guide. In addition, SOP 07-1 establishes new criteria for a parent company or equity method investor to retain investment company accounting in their consolidated financial statements. Investment companies record all their investments at fair value with changes in value reflected in earnings. S&T is currently evaluating the potential impact of adopting SOP 07-1.

RECLASSIFICATION

Certain amounts in prior years’ financial statements have been reclassed to conform to the current year’s presentation. The reclassifications had no effect on S&T’s financial condition or results of operations.

NOTE B

Market Values of Financial Instruments

S&T utilizes quoted market values, where available, to assign market value to its financial instruments. In cases where quoted market values were not available, S&T uses present value methods to estimate the market value of its financial instruments. These estimates of market value are significantly affected by the assumptions made and, accordingly, do not necessarily indicate amounts that could be realized in a current market exchange.

The following methods and assumptions were used by S&T in estimating its market value disclosures for financial instruments:

CASH AND CASH EQUIVALENTS AND OTHER SHORT-TERM ASSETS

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

SECURITIES

Market values for investment securities and securities available for sale are based on quoted market prices.

LOANS

For variable-rate loans that reprice frequently and with no significant change in credit risk, market values are based on carrying values. The market 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 market value.

DEPOSITS

The market 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 market value at year-end. Market 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.

49

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

SHORT-TERM BORROWINGS AND OTHER BORROWED FUNDS

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

LONG-TERM BORROWINGS

The market values disclosed for long-term borrowings are estimated using current interest rates for long-term borrowings of similar remaining maturities.

LOAN COMMITMENTS AND STANDBY LETTERS OF CREDIT

Estimates of the market 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, typically non-binding and fees are not normally assessed on these balances.

Estimates of market 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 market value for these types of assets, which represent significant value to S&T.

The following table indicates the estimated market value of S&T’s financial instruments as of December 31:

Restrictions on Cash and Due from Bank Accounts

The Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) imposes certain reserve requirements on all depository institutions. These reserves are maintained in the form of vault cash or as a noninterest-bearing balance with the Federal Reserve Board. Required reserves averaged $17,848,000 during 2007.

During 2007, S&T recognized other-than-temporary impairments totaling $0.1 million on three equity investment securities. S&T recognized an other-than-temporary impairment totaling $0.3 million on three equity securities during 2006. S&T does not believe any individual unrealized loss as of December 31, 2007 represents an other-than-temporary impairment. S&T performs a review on 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 market value has been less than cost and the financial condition of the issuer. As of December 31, 2007, the unrealized losses on 94 debt securities are primarily attributable to changes in interest rates. The unrealized losses on three marketable equity securities as of December 31, 2007 are attributable to temporary declines in market value. S&T has both the intent and the ability to hold the securities contained in the previous table for a time necessary to recover the amortized cost.

The amortized cost and estimated market value of debt securities at December 31, 2007, by expected maturity, is included in the table below. Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

For purposes of the maturity table, mortgage-backed securities and collateralized mortgage obligations, which are not due at a single maturity date, have been allocated over maturity groupings based upon the current estimated prepayment rates. The mortgage-backed securities and collateralized mortgage obligations may mature earlier or later than their estimated maturities because of principal prepayment optionality.

⁽¹⁾ During 2005, S&T reclassified $969,000 of its allowance for loan losses to a separate allowance for probable credit losses inherent in lending-related commitments. Net income and prior period balances were not affected by this reclassification. The separate allowance is included in other liabilities.

S&T Bank has granted loans to certain officers and directors of S&T as well as to certain affiliates of the officers and directors in the ordinary course of business. These loans were made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with unrelated persons and did not involve more than normal risk of collectability. The aggregate dollar amounts of these loans were $24,651,000 and $32,714,000 at December 31, 2007 and 2006, respectively. During 2007, $14,670,000 of new loans were funded and repayments totaled $22,732,000.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

The principal balances of loans on nonaccrual status were $16,798,000 and $19,852,000 at December 31, 2007 and 2006, respectively. Other real estate owned which is included in other assets, was $488,000 at December 31, 2007 and $523,000 at December 31, 2006.

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 December 31, 2007 and 2006, S&T had no concentrations of credit risk by industry or group. 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 mitigates these risks.

Short-Term Borrowings

Short-term borrowings are for terms under one year and were comprised of retail repurchase agreements (“REPOs”), wholesale REPOs, federal funds purchased and FHLB advances. S&T defines repurchase agreements with its local retail customers as retail REPOs; short-term wholesale REPOs are those transacted with other banks and brokerage firms. Securities pledged as collateral under these REPO financing arrangements cannot be sold or repledged by the secured party. 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 securities, residential mortgages and other loans with the FHLB of Pittsburgh.

Long-Term Borrowings

The following table is a summary of long-term borrowings:

	2007				2006
	Balance		Average Rate		Balance		Average Rate
(dollars in thousands)
Due in one year	$	50,965	5.04	%	$	20,920	5.39	%

Total	$	201,021	5.28	%	$	171,941	5.36	%

The purpose of these borrowings is to match-fund selected new loan originations, to mitigate interest-rate sensitivity risks and to take advantage of discounted borrowing rates through the FHLB for community investment projects.

S&T pledged securities and all 1-4 family and multi-family mortgage loans as collateral for any current or future FHLB borrowings. The total carrying amount of these pledged loans was $535,965,000 at December 31, 2007. At December 31, 2007, S&T had availability with the FHLB of $587,820,000.

As of December 31, 2007 and 2006, S&T had long-term repurchase agreement borrowings totaling $50.0 million at a weighted average fixed-rate with embedded floors of 5.52 percent, which mature within two years. The purpose of these borrowings was to lock in fixed-rate fundings to mitigate interest-rate risk.

On September 21, 2006, S&T Bank issued $25.0 million of junior subordinated debt through a pooled transaction at an initial fixed rate of 6.78%. On September 15, 2011 and quarterly thereafter, S&T Bank has the option to redeem the subordinated debt, subject to a 30 day written notice and prior approval by the FDIC. If S&T Bank chooses not to exercise the option for early redemption on September 15, 2011 or subsequent quarters, the subordinated debt will convert to a variable rate of 3-month LIBOR plus 160 basis points. The subordinated debt qualifies as Tier 2 capital under regulatory guidelines and will mature on December 15, 2036.

NOTE J

Dividend and Loan Restrictions

Certain restrictions exist regarding the ability of S&T Bank to transfer funds to S&T in the form of dividends and loans. The amount of dividends that may be paid to S&T is restricted by regulatory guidelines concerning minimum capital requirements. S&T Bank could pay dividends of approximately $21.3 million without affecting its well-capitalized position at December 31, 2007.

Federal law prohibits S&T from borrowing from S&T Bank unless such loans are collateralized by specific obligations. Further, such loans are limited to 10 percent of S&T Bank’s capital and additional paid-in capital, as defined.

NOTE K

Litigation

S&T, in the normal course of business, is subject to various legal proceedings in which claims for monetary damages are asserted. No material losses are anticipated by S&T as a result of these legal proceedings.

NOTE L

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 $663,124,000 and $686,204,000 at December 31, 2007 and 2006, respectively. Unfunded other loan commitments totaled $187,173,000 and $157,863,000 at December 31, 2007 and 2006, respectively; and obligations under standby letters of credit totaled $184,589,000 and $220,494,000 at December 31, 2007 and 2006, respectively.

Income Taxes

Income tax expense (credits) for the years ended December 31 are comprised of:

	2007			2006		2005
(dollars in thousands)
Current	$	23,767		$	19,711	$	23,288
Deferred		(2,140	)		1,802		999
Total	$	21,627		$	21,513	$	24,287

The provision for income taxes differs from the amount computed by applying the statutory federal income tax rate to income before income taxes. The statutory to effective tax rate reconciliation for the years ended December 31 is as follows:

	2007		2006		2005
Statutory tax rate	35.0	%	35.0	%	35.0	%
Tax-exempt interest income	(2.9	)	(2.8	)	(2.3	)

Other	(1.2	)	(1.1	)	(1.0	)
Effective tax rate	27.8	%	28.7	%	29.4	%

Income taxes applicable to security gains were $1,345,000 in 2007, $1,918,000 in 2006 and $1,753,000 in 2005.

Total deferred tax assets		17,732			17,615
Net deferred tax asset	$	3,311		$	967

S&T establishes a valuation allowance when it is more likely than not that S&T will not be able to realize the benefit of the deferred tax assets, i.e., when future deductibility is uncertain. Periodically, the valuation allowance is reviewed and adjusted based on management’s assessments of realizable deferred tax assets. Gross deferred tax assets as of December 31, 2007 and 2006 were reduced by a valuation allowance of $0.4 million and $0.3 million, respectively, related to state income tax net operating losses generated by certain subsidiaries, as utilization of these losses is not likely. These operating loss carryforwards total $5.8 million and will expire in the years 2021-2026.

The period change in deferred taxes is recorded both directly to capital and as a part of the income tax expense and can be summarized as follows at December 31:

	2007			2006
(dollars in thousands)
Deferred tax changes reflected in other comprehensive income	$	(204	)	$	(2,778	)
Deferred tax changes reflected in federal income tax expense		(2,140	)		1,802
Net change in deferred taxes	$	(2,344	)	$	(976	)

In June 2006, the FASB issued FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,” an interpretation of SFAS No. 109, “Accounting for Income Taxes,” to create a single model to address accounting for uncertainty in tax positions. FIN 48 clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. FIN 48 also provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. S&T adopted FIN 48 as of January 1, 2007, as required. The cumulative effect of adopting FIN 48 was a direct decrease to the balance of retained earnings as of January 1, 2007 of $150,666. As of the date of adoption, S&T had approximately $34,499 of interest accrued for potential tax benefits and $116,167 of unrecognized tax exposures that, if recognized, would affect the effective tax rate.

A reconciliation of the change in unrecognized tax benefits from January 1, 2007 to December 31, 2007 is as follows:

	Federal and State Gross UTB’s		Federal and State UTB’s impacting the effective income tax rate
(dollars in thousands)
Unrecognized Tax Benefits (“UTB”) Gross at January 1, 2007	792		151
Additions for tax positions related to prior years	18		66
Reductions for tax positions related to the current year	(327	)	(59	)
Reductions for tax positions related to the expiration of statutes of limitations	(483	)	(54	)
Changes relating to settlements with taxing authorities	—		—
Balance at December 31, 2007	—		104

S&T and its subsidiaries file income tax returns in the U.S. federal jurisdiction and state of domicile. S&T is not currently under audit by any jurisdictions. S&T recognized additional uncertain tax positions at adoption of FIN 48 for timing differences and related interest that was not recognized as a cumulative charge against retained earnings, but is included in the gross UTB balance in the above table. However, interest related to these items are presented as additions for tax positions related to prior years above for their impact on tax expense. S&T also recognized the favorable current year changes for existing uncertain tax positions and related interest for both Federal and State tax jurisdictions. The expiration of statutes of limitations for various jurisdictions and related interest net of federal benefits reduced S&T’s unrecognized tax benefits.

S&T monitors changes in tax statues and regulations to determine if significant changes will occur over the next 12 months. No material changes have been projected, however, management believes changes will occur at the expiration of statutes of limitations and accrual of interest. As S&T is not currently under examination, changes from settlements can not be projected, however, if this position would change it is unlikely to have a material impact on income tax expense during the next 12 months.

It is S&T’s policy to classify interest and penalties associated with income taxes as income tax expense. Total accrued interest through December 31, 2007 increased from adoption by $17,011 and totals $51,510.

NOTE N

Employee Benefits

S&T Bank maintains a defined benefit pension plan (the “Plan”) covering substantially all employees. The benefits are based on years of service and the employee’s compensation for the highest five consecutive years in the last ten years. Contributions are intended to provide for benefits attributed to employee service to date and for those benefits expected to be earned in the future.

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

The prior service cost and actuarial loss included in accumulated other comprehensive income expected to be recognized in net periodic pension cost during the year ended December 31, 2008 is $16,000 ($10,000, net of tax).

The accumulated benefit obligation for the Plan was $45,646,000 at December 31, 2007 and $43,049,000 at December 31, 2006.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

S&T considers many factors when setting the assumed rate of return on Plan assets. As a general guideline the assumed rate of return is equal to the weighted average of the expected returns for each asset category and is estimated based on historical returns as well as expected future returns. The weighted average discount rate is derived from the Treasury and Corporate yield curves.

The Plan’s weighted-average asset allocations by asset category are as follows:

	Plan Assets at December 31
Asset Category	2007		2006
Equity Securities	57	%	55	%
Debt Securities	38	%	33	%
Other	5	%	12	%
Total	100	%	100	%

S&T Bank’s Retirement Plan Committee determines the investment policy for the Plan. In general, the targeted asset allocation is 50 percent-70 percent equities and 30 percent-50 percent fixed-income. A strategic allocation within each asset class is employed based on the Plan’s time horizon, risk tolerances, performance expectations and asset class preferences. Investment managers have discretion to invest in any equity or fixed-income asset class, subject to the securities guidelines of the Plan’s Investment Policy Statement.

S&T Bank contributed $6.0 million to the Plan in 2006 for 2007 and expects to contribute zero in 2008. This contribution comprised the majority of the other asset category (e.g., money market account) at December 31, 2007. Benefit payments, which reflect expected future service, as appropriate, are expected to be paid from the Plan for each of the years 2008-2012 and are $2,130,000, $2,320,000, $2,532,000, $2,738,000, $2,927,000, respectively, and $17,874,000 for the five years thereafter.

S&T also has a supplemental executive retirement plan (“SERP”) for certain key employees. The SERP is unfunded. The balances of the actuarial present values of projected benefit obligations and accrued pension cost related to the SERP were $3,484,000 and $3,389,000 at December 31, 2007 and 2006, respectively. Accrued pension costs related to the SERP were $3,029,000 and $2,904,000 at December 31, 2007 and 2006, respectively. Net periodic pension cost related to the SERP was $302,000, $340,000 and $317,000 for the years ended December 31, 2007, 2006 and 2005, respectively. In accordance with SFAS No. 158, $292,000 and $329,000 before tax was reflected in accumulated other comprehensive income at December 31, 2007 and 2006 in relation to the SERP. The actuarial assumptions used for the SERP are the same as those used for the Plan. In addition, S&T pays the post-retirement health care for a limited number of retirees. The amounts related to post-retirement health care are not material.

S&T maintains a Thrift Plan, a qualified defined contribution plan, in which substantially all employees are eligible to participate. S&T makes matching contributions to the Thrift Plan up to 3 percent of participants’ eligible compensation and may make additional profit-sharing contributions as provided by the Thrift Plan. Expense related to these contributions amounted to $2,434,000, $1,452,000 and $1,963,000 in 2007, 2006 and 2005, respectively.

NOTE O

Incentive and Restricted Stock Plan and Dividend Reinvestment Plan

S&T adopted an Incentive Stock Plan in 1992 (“1992 Stock Plan”) that provides for granting incentive stock options, nonstatutory stock options, restricted stock and appreciation rights. On October 17, 1994, the 1992 Stock Plan was amended to include outside directors. The 1992 Stock Plan covers a maximum of 3.2 million shares of S&T common stock and expires ten years from the date of board approval. At December 31, 2002, 3,180,822 nonstatutory stock options and 35,600 restricted stock awards had been granted under the 1992 Stock Plan. No further awards will be made under the 1992 Stock Plan.

S&T adopted the 2003 Stock Plan in 2003 that provides for granting incentive stock options, nonstatutory stock options, restricted stock and appreciation rights. The 2003 Stock Plan covers a maximum of 1.5 million shares of S&T common stock and expires ten years from the date of board approval. The 2003 Stock Plan is similar to the 1992 Stock Plan, which the 2003 Stock Plan replaced. As of December 31, 2007, 937,500 nonstatutory stock options have been granted under the 2003 Stock Plan and 676,225 are currently exercisable.

On June 20, 2005, the Board of Directors approved the accelerated vesting of the December 20, 2004 stock options awarded to eligible participants under the S&T Bancorp, Inc. 2003 Stock Incentive Plan (the “2003 Stock Plan”), which had an exercise

61

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS – continued

price of $37.08. As a result of the acceleration, unvested options granted in 2004 to acquire approximately 381,000 shares of S&T’s common stock became immediately exercisable. The options were not “in the money” (i.e., the exercise price of the options were in excess of the price of S&T’s common stock) at the time of acceleration.

Nonstatutory stock options granted in 2006 and 2005 have a four-year vesting period and a ten-year life, with 25 percent vesting each year on January 1 of the succeeding year. S&T’s policy is to issue shares from treasury upon exercise of stock options. As a result of applying the provisions of SFAS No. 123(R), during 2007 and 2006, S&T recognized compensation expense of $455,000 and $452,000, pretax and $296,000 and $294,000, net of tax, respectively.

The fair value of option awards under the nonstatutory stock option plan is estimated on the date of grant using the Black-Scholes valuation methodology, which is dependent upon certain assumptions, as summarized in the following table, for the periods ending December 31. S&T uses the simplified method in developing the estimated life of the option, whereby the expected life is presumed to be the mid point between the vesting date and the end of the contractual term. There were no nonstatutory stock options granted in 2007.

	2006		2005
Risk-free interest rate	4.36	%	3.61	%
Volatility of stock	.27		.26
Expected dividend yield	3.0	%	2.9	%
Expected life of options	7 years		5 years

S&T also sponsors a Cash Appreciation Rights (“CARs”) plan which is treated as a liability instrument under SFAS No. 123(R). The CARs are settled in cash. There were no CARs granted in 2007 and 2006. 206,900 CARs were granted in 2005 at an exercise price of $37.86 and have a four-year vesting period and a ten-year life, with 25 percent vesting each year on January 1 of the succeeding year. During 2007, 9,550 CARs have been forfeited. During 2007 and 2006, S&T recognized compensation expense of ($54,000) and $325,000, pretax and ($35,000) and $211,000, net of tax, respectively. The Black-Scholes option valuation model is used to determine the market value of the CARs as of each reporting date. The assumptions used to value the CARs for the years ended December 31 were as follows:

	2007		2006		2005
Risk-free interest rate	3.54	%	4.64	%	4.36	%
Volatility of stock	.26		.26		.27
Expected dividend yield	3.77	%	3.53	%	3.00	%
Expected life of options	5.10 years		5.98 years		7.00 years

S&T also periodically issues restricted stock to employees and directors. On April 16, 2007, 7,761 restricted stock awards were granted to outside directors. These shares will vest on April 16, 2008. On December 17, 2007, 35,199 restricted stock awards were granted to senior management. The awards to senior management were granted in accordance with 2007 performance levels and primarily based on earnings per share growth. These shares will vest 25 percent per year with the first vesting to occur on January 1, 2009. During the restricted period, the recipient receives dividends and can vote the shares. Generally, if the recipient leaves S&T before the end of the restricted period, the shares will be forfeited. Compensation expense for the restricted stock is ratably recognized over the period of service, generally the restricted period, based on the market value of the stock on the date of grant. During 2007 and 2006, S&T recognized compensation expense of $622,000 and $59,000, pretax and $404,000 and $38,000, net of tax, respectively.

Regulatory Matters

S&T is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on S&T’s financial statements. Under capital guidelines and the regulatory framework for prompt corrective action, S&T must meet specific capital guidelines that involve quantitative measures of S&T’s assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. S&T’s capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

Quantitative measures established by regulation to ensure capital adequacy require S&T to maintain minimum amounts and ratios of Tier 1 and Total capital to risk-weighted assets and Tier 1 capital to average assets. As of December 31, 2007 and 2006, S&T meets all capital adequacy requirements to which it is subject.

To be classified as well capitalized, S&T must maintain minimum Tier 1 risk-based, Total risk-based and Tier 1 leverage ratios as set forth in the table below:

	Actual				For Capital Adequacy Purposes			To Be Well Capitalized Under Prompt Corrective Action Provisions
	Amount		Ratio		Amount	Ratio		Amount	Ratio
(dollars in thousands)
As of December 31, 2007
Total Capital (to Risk Weighted Assets)	$	345,611	11.64	%	$237,553	8.00	%	$296,942	10.00	%
Tier 1 Capital (to Risk Weighted Assets)		281,995	9.50	%	118,777	4.00	%	178,165	6.00	%
Tier 1 Capital (to Average Assets)		281,995	8.57	%	98,686	3.00	%	164,477	5.00	%
As of December 31, 2006
Total Capital (to Risk Weighted Assets)	$	347,487	11.93	%	$233,085	8.00	%	$291,356	10.00	%
Tier 1 Capital (to Risk Weighted Assets)		282,030	9.68	%	116,543	4.00	%	174,814	6.00	%
Tier 1 Capital (to Average Assets)		282,030	8.84	%	95,755	3.00	%	159,591	5.00	%

The most recent notifications from the Federal Reserve Bank and the FDIC categorized S&T and S&T Bank, respectively, as well capitalized under the regulatory framework for corrective action. There have been no conditions or events that management believes have changed S&T or S&T Bank’s ranking during 2007 and 2006.

At December 31, 2007, S&T Bank’s Tier 1 and Total capital ratios were 8.68 percent and 10.72 percent, respectively, and Tier 1 capital to average assets was 7.82 percent. At December 31, 2006, S&T Bank’s Tier 1 and Total capital ratios were 8.54 percent and 10.64 percent, respectively, and Tier 1 capital to average assets was 7.74 percent.

REPORT OF MANAGEMENT

S&T Bancorp, Inc. and Subsidiaries

S&T Bancorp, Inc. is responsible for the preparation, integrity, and fair presentation of the consolidated financial statements included in this annual report. The consolidated financial statements and notes included in this annual report have been prepared in conformity with United States generally accepted accounting principles and necessarily include some amounts that are based on management’s best estimates and judgments.

We, as management of S&T Bancorp, Inc., are responsible for establishing and maintaining effective adequate control over financial reporting that is designed to produce reliable financial statements in conformity with United States generally accepted accounting principles. The system of internal control over financial reporting as it relates to the financial statements is evaluated for effectiveness by management and tested for reliability through a program of internal audits. Actions are taken to correct potential deficiencies as they are identified. Any system of internal control, no matter how well designed, has inherent limitations, including the possibility that a control can be circumvented or overridden and misstatements due to error or fraud may occur and not be detected. Also, because of changes in conditions, internal control effectiveness may vary over time. Accordingly, even an effective system of internal control will provide only reasonable assurance with respect to financial statement preparation.

The Audit Committee, consisting entirely of independent directors, meets regularly with management, internal auditors and the independent registered public accounting firm, and reviews audit plans and results, as well as management’s actions taken in discharging responsibilities for accounting, financial reporting and internal control. KPMG LLP, independent registered public accounting firm, and the internal auditors have direct and confidential access to the Audit Committee at all times to discuss the results of their examinations.

REPORT ON MANAGEMENT’S ASSESSMENT OF INTERNAL CONTROL OVER FINANCIAL REPORTING

Management assessed the corporation’s system of internal control over financial reporting as of December 31, 2007, in relation to criteria for effective internal control over financial reporting as described in “Internal Control—Integrated Framework,” issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management concludes that, as of December 31, 2007, its system of internal control over financial reporting is effective based on the criteria of the “Internal Control—Integrated Framework”. KPMG LLP, independent registered public accounting firm, has issued an attestation report on effectiveness of the Corporation’s internal control over financial reporting.

Report of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders

S&T Bancorp, Inc.:

We have audited S&T Bancorp, Inc.’s (the Company) internal control over financial reporting as of December 31, 2007, based on the criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). S&T Bancorp, Inc.’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Report on Management’s Assessment of Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

In our opinion, S&T Bancorp, Inc. maintained, in all material respects, effective internal control over financial reporting as of December 31, 2007, based on criteria established in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheet of S&T Bancorp, Inc. as of December 31, 2007, and the related consolidated statements of income, shareholders’ equity, and cash flows for the year then ended, and our report dated February 29, 2008 expressed an unqualified opinion on those consolidated financial statements.

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of S&T Bancorp, Inc. and subsidiaries as of December 31, 2007, and the results of their operations and their cash flows for the year then ended, in conformity with U.S. generally accepted accounting principles.
