Celestica Safe Harbor and Fair Disclosure Statement

This news release contains forward-looking statements related to our future growth, our financial or operational results including our quarterly earnings and revenue guidance, and the impact of winding down of our manufacturing services for RIM on our financial results and working capital requirements, and anticipated expenses and restructuring charges related to the RIM wind down. Such forward-looking statements are predictive in nature and may be based on current expectations, forecasts or assumptions involving risks and uncertainties that could cause actual outcomes and results to differ materially from the forward-looking statements themselves.  Such forward-looking statements may, without limitation, be preceded by, followed by, or include words such as “believes”, “expects”, “anticipates”, “estimates”, “intends”, “plans”, “continues”, or similar expressions, or may employ such future or conditional verbs as “may”, “will”, “should” or “would”, or may otherwise be indicated as forward-looking statements by grammatical construction, phrasing or context.  For those statements, we claim the protection of the safe harbor for forward-looking statements contained in the U.S. Private Securities Litigation Reform Act of 1995, and in applicable Canadian securities legislation. Forward-looking statements are not guarantees of future performance. Readers should understand that the following important factors could affect our future results and could cause those results to differ materially from those expressed in such forward-looking statements: the challenges of effectively managing the winding down of manufacturing services for RIM and the duration of such wind down,  the extent of the restructuring charges associated with the RIM wind down, our dependence on a limited number of customers and on our customers’ ability to compete and succeed in their marketplace for the products we manufacture; the effects of price competition and other business and competitive factors generally affecting the electronics manufacturing services (EMS) industry; the challenges of effectively managing our operations and our working capital performance during uncertain economic conditions, including responding to significant changes in demand from our customers, including RIM; the challenges of managing changing commodity costs as well as labor costs and conditions; disruptions to our operations, or those of our customers, component suppliers, or our logistics partners, resulting from local events including natural disasters, political instability, local labor conditions and social unrest, criminal activity and other risks present in the jurisdictions in which we operate; our inability to retain or expand our business due to execution problems relating to the ramping of new programs; the delays in the delivery and/or general availability of various components and materials used in our manufacturing process; the challenge of managing our financial exposure to foreign currency volatility; our dependence on industries affected by rapid technological change; variability of operating results among periods; our ability to successfully manage our international operations; increasing income taxes and our ability to successfully defend tax audits or meet the conditions of tax incentives; the completion of our restructuring activities or integration of any  acquisitions; and the risk of potential non-performance by counterparties, including but not limited to financial institutions, customers and suppliers. These and other risks and uncertainties, as well as other information related to the company, are discussed in the company’s various public filings at www.sedar.com and www.sec.gov, including our Annual Report on Form 20-F and subsequent reports on Form 6-K filed with the U.S. Securities and Exchange Commission and our Annual Information Form filed with the Canadian securities regulators. Forward-looking statements are provided for the purpose of providing information about management’s current expectations and plans relating to the future.  Readers are cautioned that such information may not be appropriate for other purposes. Except as required by applicable law, we disclaim any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

Our revenue and earnings guidance and estimated restructuring charges, as contained in this press release, are based on various assumptions which management believes are reasonable under the current circumstances, but may prove to be inaccurate, and many of which involve factors that are beyond the control of the company. The material assumptions may include the following: our ability to effectively manage the RIM wind down and the duration of such wind down, forecasts from all of our customers, including RIM, which range from 30 to 90 days and can fluctuate significantly in terms of volume and mix of products or services; the timing and execution of, and investments associated with ramping new business; the success in the marketplace of our customers’ products, general economic and market conditions; currency exchange rates; pricing and competition; anticipated customer demand; supplier performance and pricing; commodity, labor, energy and transportation costs; operational and financial matters; and technological developments. These assumptions and estimates are based on management’s current views with respect to current plans and events, and are and will be subject to the risks and uncertainties referred to above.  It is Celestica’s policy that revenue and earnings guidance is effective on the date given, and will only be updated through a public announcement.
