Safe Harbor Statement
Forward Looking Statements
Some of the statements in this presentation are forward-looking statements (or forward-looking information) within the meaning of applicable U.S. and Canadian securities laws. These include statements using the words target, outlook, may, will, should, could, estimate, continue, expect, intend, plan, predict, potential, project and anticipate, and similar statements which do not describe the present or provide information about the past. Actual results may differ materially from those presented in forward-looking statements. Material risks that could cause actual results to differ include: our ability to achieve or sustain profitability in the future; fluctuations in our quarterly and annual revenues and operating results; fluctuations in foreign exchange rates; current and ongoing global economic instability; intense competition; our reliance on channel partners for a significant component of our sales; our dependence upon a small number of outside contract manufacturers to manufacture our products; our ability to successfully integrate acquisitions; and, our ability to implement and achieve our business strategies successfully. Additional risks are described under the heading “Risk Factors” in Mitel’s Annual Report on Form 10-K. We have made assumptions regarding, among other things: no unforeseen changes occurring in the competitive landscape that would affect our industry generally or Mitel in particular; a stable or recovering economic environment; no significant event occurring outside the ordinary course of our business; and, stable foreign exchange and interest rates. Forward-looking information is intended to help you understand management’s current views of our future prospects, and it may not be appropriate for other purposes. Except as required by law, Mitel will not necessarily update forward-looking statements.
Non-GAAP Financial Measurements
This presentation includes references to non-GAAP financial measures including adjusted EBITDA, non-GAAP income and non-GAAP operating expenses. Non-GAAP financial measures do not have any standardized meaning and are therefore unlikely to be comparable to similar measures presented by other companies. We use these non-GAAP financial measures to assist management and investors in understanding our past financial performance and prospects for the future, including changes in our operating results, trends and marketplace performance, exclusive of unusual events or factors which do not directly affect what we consider to be our core operating performance. Non-GAAP measures are among the primary indicators management uses as a basis for our planning and forecasting of future periods. Investors are cautioned that non-GAAP financial measures should not be relied upon as a substitute for financial measures prepared in accordance with generally accepted accounting principles. Please see the reconciliation of non-GAAP financial measures to the most directly comparable U.S. GAAP measure included in this presentation and, if not contained in this presentation, contained in Mitel’s
Reports on Form 8-K which have been filed with the U.S. Securities and Exchange Commission on June 24, 2013 (fiscal 2013) and August 29, 2013 (Q1 of fiscal 2014).
