Wesco Aircraft Private & Proprietary Disclaimer 3 Wesco Aircraft Investor Relations This presentation contains forward-looking statements (including within the meaning of the Private Securities Litigation Reform Act of 1995) concerning Wesco Aircraft Holdings, Inc. (“Wesco Aircraft “ or the “Company”), the acquisition of Haas Group Inc. (“Haas”) and other matters. These statements may discuss goals, intentions and expectations as to future plans, trends, events, results of operations or financial condition, or otherwise, based on current beliefs of management, as well as assumptions made by, and information currently available to, such management. Forward-looking statements may be accompanied by words such as “aim,” “anticipate,” “believe,” “plan,” “could,” “would,” “should,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “will,” “possible,” “potential,” “predict,” “project” or similar words, phrases or expressions. These forward-looking statements are subject to various risks and uncertainties, many of which are outside the Company’s control. Therefore, you should not place undue reliance on such statements. Factors that could cause actual results to differ materially from those in the forward-looking statements include: risks that the businesses of Wesco Aircraft and Haas will not be integrated successfully or that the combined company will not realize estimated cost savings, synergies and growth or that such benefits may take longer to realize than expected; failure to realize anticipated benefits of the combined operations; risks relating to unanticipated costs of integration; changes in legislation or governmental regulations affecting the Company; international, national or local economic, social or political conditions that could adversely affect the Company or its customers; conditions in the credit markets; risks associated with assumptions the Company makes in connection with its critical accounting estimates and legal proceedings; the condition of the aerospace industry; reductions in military spending; business risks as a result of supplying equipment and services to the U.S. Government; risks associated with the Company’s long-term, fixed-price agreements, which have no guarantee of future sales volume; risks associated with the loss of a significant customer; the Company’s failure to compete successfully in its highly competitive global industry; risks associated with the Company’s rapid expansion; supply-chain risk; the Company’s dependence on complex information technology; environmental risks; and the Company’s dependence on key personnel. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties that affect the Company’s business, including those described in the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other documents filed from time to time with the Securities and Exchange Commission.

The Company utilizes and discusses Adjusted Net Income, Adjusted Basic EPS, Adjusted Diluted EPS and Adjusted EBITDA, which are non-GAAP measures its management uses to evaluate its business, because the Company believes they assist investors and analysts in comparing its performance across reporting periods on a consistent basis by excluding items that the Company does not believe are indicative of its core operating performance. The Company believes these metrics are used in the financial community, and it presents these metrics to enhance investors’ understanding of its operating performance. You should not consider Adjusted EBITDA and Adjusted Net Income as an alternative to Net Income, determined in accordance with GAAP, as an indicator of operating performance. Adjusted Net Income, Adjusted Basic EPS, Adjusted Diluted EPS and Adjusted EBITDA are not measurements of financial performance under GAAP, and these metrics may not be comparable to similarly titled measures of other companies. See the Appendix for a reconciliation of Adjusted Net Income, Adjusted Basic EPS, Adjusted Diluted EPS and Adjusted EBITDA to the most directly comparable financial measures calculated and presented in accordance with GAAP.
