3 Disclaimer Safe Harbor Statement The following information contains, or may be deemed to contain, “forward-looking statements” (as defined in the U.S. Private Securities Litigation Reform Act of 1995). Most forward-looking statements contain words that identify them as forward-looking, such as “may”, “plan”, “seek”, “will”, “expect”, “intend”, “estimate”, “anticipate”, “believe”, “project”, “opportunity”, “target”, “goal”, “growing” and “continue” or other words that relate to future events, as opposed to past or current events. By their nature, forward-looking statements are not statements of historical facts and involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. These statements give Wesco Aircraft’s current expectation of future events or its future performance and do not relate directly to historical or current events or Wesco Aircraft’s historical or future performance. As such, Wesco Aircraft’s future results may vary from any expectations or goals expressed in, or implied by, the forward-looking statements included in this presentation, possibly to a material degree. Wesco Aircraft cannot assure you that the assumptions made in preparing any of the forward-looking statements will prove accurate or that any long-term financial goals will be realized. All forward-looking statements included in this presentation speak only as of the date made, and Wesco Aircraft undertakes no obligation to update or revise publicly any such forward-looking statements, whether as a result of new information, future events, or otherwise. In particular, Wesco Aircraft cautions you not to place undue weight on certain forward-looking statements pertaining to potential growth opportunities, long-term financial projections or goals, future growth or the value we currently ascribe to certain attributes set forth herein. Actual results may vary significantly from these statements. Wesco Aircraft’s business is subject to numerous risks and uncertainties, which may cause future results of operations to vary significantly from those presented herein, including those highlighted in the section entitled “Risk Factors” in Wesco Aircraft’s registration statement on Form S-1 filed with the Securities and Exchange Commission on July 15, 2011. Wesco Aircraft discloses Adjusted EBITDA and Adjusted Net Income, which are non-GAAP measures its management uses to evaluate its business, because it believes they assist investors and analysts in comparing its performance across reporting periods on a consistent basis by excluding items that Wesco Aircraft does not believe are indicative of its core operating performance. Wesco Aircraft believes these metrics are used in the financial community, and it presents these metrics to enhance investors’ understanding of its operating performance and cash flow. 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, or as an alternative to net cash provided by operating activities, determined in accordance with GAAP, as an indicator of Wesco Aircraft’s cash flow. See the Appendix for reconciliations of Adjusted EBITDA and Adjusted Net Income to GAAP net income.
