Business Unit Results

• Mitel Communications Solutions revenues for the first quarter of fiscal 2012 grew 1% to $124.4 million from the same quarter of 2011. Operating margin declined 1.6% versus the prior year reflecting increased product margins being offset by a decline in service margins and higher operating expenses.
• Mitel NetSolutions revenues for the first quarter of fiscal 2012 grew 4% to $20.0 million from the same quarter of 2011. Operating margin declined by 0.4% over the same period due to the investment in Mitel Mobile and Mitel AnyWare capabilities.
• Mitel DataNet revenue for the first quarter of fiscal 2012 grew 14% to $19.7 million from the same quarter of 2011. Operating margin improved by 4.3% over the same period due primarily to higher gross margins resulting from a combination of revenue mix and improved purchasing power due to higher volumes.

• New customer highlights:

• Hancock Estabrook selected Mitel's Freedom architecture to allow its attorneys the ability to work flexibly and effectively from any location. The solution provides seamless, unified communications between the firm's 60+ lawyers and their clients.

• The Mitel Application Suite Release 3.0 has been introduced to market, which integrates Mitel's Unified Communicator Advanced server software and desktop/mobile client support directly into this suite. This further streamlines Mitel's UCC solution offering and improves implementation and management.

Adjusted EBITDA

For a reconciliation of Adjusted EBITDA to net income, the most directly comparable U.S. GAAP measure, see attached "Reconciliation of Net Income to Adjusted EBITDA."

Adjusted EBITDA is not a measure calculated in accordance with U.S. GAAP. Adjusted EBITDA should not be considered as an alternative to net income, income from operations or any other measure of financial performance calculated and presented in accordance with U.S. GAAP. We prepare Adjusted EBITDA to eliminate the impact of items that we do not consider indicative of our core operating performance. We encourage you to evaluate these adjustments and the reasons we consider them appropriate, as well as the material limitations of non-GAAP measures and the manner in which we compensate for those limitations. See "Selected Financial Data" in Mitel's Annual Report on Form 10-K, which has been filed with the U.S. Securities and Exchange Commission on July 1, 2011 and filed with Canadian securities authorities.

Non-GAAP Financial Measurements

To supplement our consolidated financial statements presented on a GAAP basis, Mitel uses non-GAAP measures of operating results, net income and income per share, which are adjusted to exclude certain costs, expenses, gains and losses we believe appropriate to enhance an overall understanding of our past financial performance and also our prospects for the future. These adjustments to our current period and comparative prior period GAAP results are made with the intent of providing both management and investors a more complete understanding of Mitel's underlying operational results and trends and our marketplace performance. For example, the non-GAAP results are an indication of our baseline performance before gains, losses or other charges that are considered by management to be outside of our core operating results. In addition, these adjusted non-GAAP results are among the primary indicators management uses as a basis for our planning and forecasting of future periods. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income or diluted net income per share prepared in accordance with generally accepted accounting principles in the U.S.
