NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

FOR THE QUARTERLY PERIOD ENDED MARCH 31, 2011 (UNAUDITED)

1. BUSINESS

Wabtec is one of the world’s largest providers of value-added, technology-based products and services for the global rail industry. Our products are found on virtually all U.S. locomotives, freight cars and passenger transit vehicles, as well as in approximately 100 countries throughout the world. Our products enhance safety, improve productivity and reduce maintenance costs for customers, and many of our core products and services are essential in the safe and efficient operation of freight rail and passenger transit vehicles. Wabtec is a global company with operations in 17 countries. In the first three months of 2011, about 44% of the Company’s revenues came from customers outside the U.S.

2. ACCOUNTING POLICIES

Basis of Presentation The unaudited condensed consolidated interim financial statements have been prepared in accordance with generally accepted accounting principles and the rules and regulations of the Securities and Exchange Commission and include the accounts of Wabtec and its majority owned subsidiaries. These condensed interim financial statements do not include all of the information and footnotes required for complete financial statements. In Management’s opinion, these financial statements reflect all adjustments of a normal, recurring nature necessary for a fair presentation of the results for the interim periods presented. Results for these interim periods are not necessarily indicative of results to be expected for the full year.

The Company operates on a four-four-five week accounting quarter, and accordingly, the quarters end on or about March 31, June 30, September 30 and December 31.

The notes included herein should be read in conjunction with the audited consolidated financial statements included in Wabtec’s Annual Report on Form 10-K for the year ended December 31, 2010. The December 31, 2010 information has been derived from the Company’s Annual Report on Form 10-K for the year ended December 31, 2010.

Reclassifications Certain prior year amounts have been reclassified where necessary to conform to the current year presentation.

Revenue Recognition Revenue is recognized in accordance with Accounting Standards Codification (“ASC”) 605 “Revenue Recognition”. Revenue is recognized when products have been shipped to the respective customers, title has passed and the price for the product has been determined.

The Company recognizes revenues on long-term contracts based on the percentage of completion method of accounting. The units-of-delivery method or other input-based or output-based measures, as appropriate, are used to measure the progress toward completion of individual contracts. Contract revenues and cost estimates are reviewed and revised at a minimum quarterly and adjustments are reflected in the accounting period as such amounts are determined. Provisions are made currently for estimated losses on uncompleted contracts.

Certain pre-production costs relating to long-term production and supply contracts have been deferred and will be recognized over the life of the contracts. Deferred pre-production costs were $12.8 million and $11.9 million at March 31, 2011 and December 31, 2010, respectively.

Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the financial statements and reported amounts of revenues and

expenses during the reporting period. Actual amounts could differ from the estimates. On an ongoing basis, management reviews its estimates based on currently available information. Changes in facts and circumstances may result in revised estimates.

Stock-Based Compensation The Company recognizes compensation expense for stock-based compensation based on the grant date fair value ratably over the requisite service period following the date of grant.

Financial Derivatives and Hedging Activities The Company has periodically entered into foreign currency forward contracts to reduce the impact of changes in currency exchange rates. Forward contracts are agreements with a counter-party to exchange two distinct currencies at a set exchange rate for delivery on a set date at some point in the future. There is no exchange of funds until the delivery date. At the delivery date the Company can either take delivery of the currency or settle on a net basis.

At March 31, 2011, the Company had forward contracts for the sale of South African Rand (ZAR) and the purchase of U.S. Dollars (USD). The Company concluded that these foreign currency forward contracts qualify for cash flow hedge accounting which permits the recording of the fair value of the forward contract and corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet. As of March 31, 2011, the Company had forward contracts with a notional value of 24.3 million ZAR (or $3.4 million U.S.) with an average exchange rate of 7.20 ZAR per $1 USD, resulting in the recording of a current liability of $155,000 and a corresponding offset in accumulated other comprehensive income of $99,000, net of tax.

To reduce the impact of interest rate changes on a portion of its variable-rate debt, the Company entered into interest rate swaps which effectively converted a portion of the debt from variable to fixed-rate borrowings during the term of the swap contracts. The Company is exposed to credit risk in the event of nonperformance by the counterparties. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparties are large financial institutions with an excellent credit rating and history of performance. The Company currently believes the risk of nonperformance is negligible. The Company concluded that these interest rate swap agreements qualify for cash flow hedge accounting which permits the recording of the fair value of the interest rate swap agreements and corresponding adjustment to other comprehensive income (loss), net of tax, on the balance sheet. As of March 31, 2011, the Company had interest rate swap agreements with a notional value of $137.0 million and which effectively changed the Company’s interest rate on bank debt at March 31, 2011 from a variable rate to a fixed rate of 2.26%. The interest rate swap agreements mature at various times through December 2012. As of March 31, 2011, the Company has recorded a current liability of $2.2 million and a corresponding offset in accumulated other comprehensive loss of $1.3 million, net of tax, related to these agreements.

Foreign Currency Translation Assets and liabilities of foreign subsidiaries, except for the Company’s Mexican operations whose functional currency is the U.S. Dollar, are translated at the rate of exchange in effect on the balance sheet date while income and expenses are translated at the weighted average rates of exchange prevailing during the year. Foreign currency gains and losses resulting from transactions, and the translation of financial statements are recorded in the Company’s consolidated financial statements based upon the provisions of ASC 830 “Foreign Currency Matters.” The effects of currency exchange rate changes on intercompany transactions and balances of a long-term investment nature are accumulated and carried as a component of shareholders’ equity. The effects of currency exchange rate changes on transactions that are denominated in a currency other than an entity’s functional currency are charged or credited to earnings. Foreign exchange transaction gains recognized in other income (expense), net were $323,000 for the three months ended March 31, 2011. Foreign exchange transaction losses recognized in other (expense) income, net were $597,000 for the three months ended March 31, 2010.

Non-controlling Interests In accordance with ASC 810, the Company has classified non-controlling interests as equity on our condensed consolidated balance sheets as of March 31, 2011 and December 31, 2010. Net income attributable to non-controlling interests for the three months ended March 31, 2011 and 2010 was not material.

Other Comprehensive Income Comprehensive income is defined as net income and all other non-owner changes in shareholders’ equity. The Company’s accumulated other comprehensive income consists of foreign currency translation adjustments, foreign currency hedges, foreign exchange contracts, interest rate swaps, and pension and post retirement related adjustments. Total comprehensive income was:

Long-term debt consisted of the following:

2008 Refinancing Credit Agreement

On November 4, 2008, the Company refinanced its existing unsecured revolving credit agreement with a consortium of commercial banks. This “2008 Refinancing Credit Agreement” provides the company with a $300 million five-year revolving credit facility and a $200 million five-year term loan facility. The Company incurred $2.9 million of deferred financing cost related to the 2008 Refinancing Credit Agreement. Both facilities expire in January 2013. The 2008 Refinancing Credit Agreement borrowings bear variable interest rates indexed to the indices described below. At March 31, 2011, the Company had available bank borrowing capacity, net of $47.8 million of letters of credit, of approximately $120.2 million, subject to certain financial covenant restrictions.

Under the 2008 Refinancing Credit Agreement, the Company may elect a Base Rate of interest or an interest rate based on the London Interbank Offered Rate (“LIBOR”) of interest (“the Alternate Rate”). The Base Rate adjusts on a daily basis and is the greater of the PNC, N.A. prime rate, 30-day LIBOR plus 150 basis points or the Federal Funds Effective Rate plus 0.5% per annum, plus a margin that ranges from 25 to 50 basis points. The Alternate rate is based on quoted LIBOR rates plus a margin that ranges from 125 to 200 basis points. Both the Base Rate and Alternate Rate margins are dependent on the Company’s consolidated total indebtedness to cash flow ratios. The initial Base Rate margin is 25 basis points and the Alternate Rate margin is 125 basis points. At March 31, 2011 the weighted average interest rate on the Company’s variable rate debt was 1.52%. To reduce the impact of interest rate changes on a portion of this variable-rate debt, the Company entered into interest rate swaps which effectively converted a portion of the debt from variable to fixed-rate borrowings during the term of the swap contracts. On March 31, 2011, the notional value of the interest rate swaps outstanding was $137.0 million and effectively changed the Company’s interest rate on bank debt at March 31, 2011 from a variable rate to a fixed rate of 2.26%. The interest rate swap agreements mature at various times through December 2012. The Company is exposed to credit risk in the event of nonperformance by the counterparties. However, since only the cash interest payments are exchanged, exposure is significantly less than the notional amount. The counterparties are large financial institutions with an excellent credit rating and history of performance. The Company currently believes the risk of nonperformance is negligible.

The 2008 Refinancing Credit Agreement limits the Company’s ability to declare or pay cash dividends and prohibits the Company from declaring or making other distributions, subject to certain exceptions. The 2008 Refinancing Credit Agreement contains various other covenants and restrictions including the following limitations: incurrence of additional indebtedness; mergers, consolidations, sales of assets and acquisitions; additional liens; sale and leasebacks; permissible investments, loans and advances; certain debt payments; and imposes a minimum interest expense coverage ratio of 3.0 and a maximum debt to cash flow ratio of 3.25. The Company is in

compliance with these measurements and covenants and expects that these measurements will not be any type of limiting factor in executing our operating activities.

On January 28, 2011, the Company entered into Amendment No. 1 to the 2008 Refinancing Credit Agreement. The amendment increased the limit on surety bonds, performance bonds, bid bonds, or similar obligations arising in the ordinary course of business from $350 million to $500 million in the aggregate. The amendment also expanded the definition of Issuing Lender to allow additional banks to issue Letters of Credit.

6.875% Senior Notes Due August 2013

In August 2003, the Company issued $150 million of Senior Notes due in 2013 (“the Notes”). The Notes were issued at par. Interest on the Notes accrues at a rate of 6.875% per annum and is payable semi-annually on January 31 and July 31 of each year. The proceeds were used to repay debt outstanding under the Company’s existing credit agreement, and for general corporate purposes. The principal balance is due in full at maturity.

The Notes are senior unsecured obligations of the Company and rank pari passu with all existing and future senior debt and senior to all existing and future subordinated indebtedness of the Company. The indenture under which the Notes were issued contains covenants and restrictions which limit among other things, the following: the incurrence of indebtedness, payment of dividends and certain distributions, sale of assets, change in control, mergers and consolidations and the incurrence of liens.

7. EMPLOYEE BENEFIT PLANS

Defined Benefit Pension Plans

The Company sponsors defined benefit pension plans that cover certain U.S., Canadian, German, and United Kingdom employees and which provide benefits of stated amounts for each year of service of the employee.

The Company uses a December 31 measurement date for the plans. The following tables provide information regarding the Company’s defined benefit pension plans summarized by U.S. and international components.

Post Retirement Benefit Plans

In addition to providing pension benefits, the Company has provided certain unfunded postretirement health care and life insurance benefits for a portion of North American employees. The Company is not obligated to pay health care and life insurance benefits to individuals who had retired prior to 1990.

The Company uses a December 31 measurement date for all post retirement plans. The following tables provide information regarding the Company’s post retirement benefit plans summarized by U.S. and international components.

8. STOCK-BASED COMPENSATION

As of March 31, 2011, the Company maintains employee stock-based compensation plans for stock options, restricted stock, and incentive stock awards as governed by the 2000 Stock Incentive Plan, as amended (the “2000 Plan”). The Company also maintains a Non-Employee Directors’ Fee and Stock Option Plan (“Directors Plan”). No awards may be made under either plan subsequent to October 31, 2016.

Stock-based compensation expense was $3.4 million and $2.5 million for the three months ended March 31, 2011 and 2010, respectively. Included in the stock-based compensation expense for 2011 above is $609,000 of expense related to stock options, $1.0 million related to restricted stock, $1.6 million related to incentive stock awards and $225,000 related to awards issued for Directors’ fees. At March 31, 2011, unamortized compensation expense related to stock options, restricted stock and incentive stock awards expected to vest totaled $25.7 million and will be recognized over a weighted average period of 1.8 years.

Stock Options Stock options are granted to eligible employees and directors at the fair market value, which is the average of the high and low Wabtec stock price on the date of grant. Under the 2000 Plan, options become exercisable over a four-year vesting period and expire 10 years from the date of grant. Under the Directors Plan, options become exercisable over a three-year vesting period and expire 10 years from the date of grant.

FOR THE QUARTERLY PERIOD ENDED MARCH 31, 2011 (UNAUDITED)

The following table summarizes the Company’s stock option activity and related information for both the 2000 Plan and Directors Plan for the three months ended March 31, 2011:

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model with the following weighted-average assumptions:

The dividend yield is based on the Company’s dividend rate and the current market price of the underlying common stock at the date of grant. Expected life in years is determined from historical stock option exercise data. Expected volatility is based on the historical volatility of the Company’s stock. The risk-free interest rate is based on the U.S. Treasury bond rates for the expected life of the option.

Restricted Stock and Incentive Stock Awards Under the 2000 Plan, the Company adopted a restricted stock plan in 2006. Eligible employees are granted restricted stock that generally vests over four years from the date of grant. Under the Directors Plan, restricted stock awards vest one year from the date of grant.

In addition, the Company has issued incentive stock awards to eligible employees that vest upon attainment of certain cumulative three year performance goals. The incentive stock awards included in the table below represent the number of shares that may ultimately vest. As of March 31, 2011, based on the Company’s performance, we estimate that these stock awards will vest and have recorded compensation expense accordingly. If our estimate of the number of these stock awards expected to vest changes in a future accounting period, compensation expense could be reduced or increased and will be recognized over the remaining vesting period.

Compensation expense for the restricted stock and incentive stock awards is based on the average of the high and low Wabtec stock price on the date of grant and recognized over the applicable vesting period.

The following table summarizes the restricted stock activity for both the 2000 Plan and Directors Plan and incentive stock awards activity for the 2000 Plan with related information for the three months ended March 31, 2011:

9. INCOME TAXES

The overall effective income tax rate was 35.2% and 34.8% for the three months ended March 31, 2011 and 2010, respectively.

As of March 31, 2011, the liability for income taxes associated with uncertain tax positions is $10.0 million, of which $3.1 million, if recognized would favorably affect the Company’s effective tax rate. As of December 31, 2010 the liability associated with uncertain tax positions was $10.0 million, of which $3.1 million, if recognized, would favorably affect the Company’s effective tax rate.

The Company includes interest and penalties related to uncertain tax positions in income tax expense. As of March 31, 2011 the total accrued interest and penalties are $3.1 million and $1.7 million, respectively. As of December 31, 2010 the total accrued interest and penalties were $3.1 million and $1.7 million, respectively.

The Internal Revenue Service is currently auditing the 2008 and 2009 tax years. With limited exception, the Company is no longer subject to examination by various U.S. and foreign taxing authorities for the years before 2007.

At this time, the Company believes that it is reasonably possible that unrecognized tax benefits of approximately $3.4 million may change within the next twelve months due to the expiration of statutory review periods and current examinations.

10. EARNINGS PER SHARE

The computation of basic and diluted earnings per share for net income attributable to Wabtec shareholders is as follows:

The Company’s non-vested restricted stock contains rights to receive nonforfeitable dividends, and thus, are participating securities requiring the two-class method of computing earnings per share. The calculation of earnings per share for common stock shown above excludes the income attributable to the non-vested restricted stock from the numerator and excludes the dilutive impact of those shares from the denominator.

12. FAIR VALUE MEASUREMENT

ASC 820 “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value and explains the related disclosure requirements. ASC 820 indicates, among other things, that a fair value measurement assumes that the transaction to sell an asset or transfer a liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability and defines fair value based upon an exit price model.

Valuation Hierarchy. ASC 820 establishes a valuation hierarchy for disclosure of the inputs to valuation used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

The following table provides the liabilities carried at fair value measured on a recurring basis as of March 31, 2011, which are included in other current liabilities on the Condensed Consolidated Balance sheet:
