Forward-Looking Safe Harbor Statement
This presentation contains certain forward-looking statements, as that term is defined in the Private Securities Litigation Reform Act of 1995, including those relating to anticipated fiscal 2006 business performance and the result of acquisitions. You can identify these statements by our use of the words “may,” “will,” “should,” “plans,” “expects,” “anticipates,” “continue,” “estimate,” “project,” “intend,” and similar expressions. These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected or anticipated. Such risks and uncertainties include, but are not limited to, general economic and business conditions, including unforeseen economic weakness in the Company’s markets, effects of continued geo-political unrest and regional conflicts, competition, changes in technology and methods of marketing, delays in completing various engineering and manufacturing programs, changes in customer order patterns, changes in product mix, continued success in technological advances and delivering technological innovations, continued funding of defense programs, timing of such funding, market acceptance of the Company’s products, shortages in components, production delays due to performance quality issues with outsourced components, failure of the parties to satisfy the closing conditions related to the Echotek Corp. acquisition, inability to fully realize the expected benefits from acquisitions or delays in realizing such benefits, challenges in integrating acquired businesses and achieving anticipated synergies, difficulties in retaining key employees and customers, and various other factors beyond the Company’s control. These risks and uncertainties also include such additional risk factors as are discussed in the Company’s recent filings with the U.S. Securities and Exchange Commission, including its Quarterly Report on Form 10-Q for the quarter ended March 31, 2005. The Company cautions readers not to place undue reliance upon any such forward-looking statements, which speak only as of the date made. The Company undertakes no obligation to update any forward-looking statement to reflect events or circumstances after the date on which such statement is made. The Company may, in its discretion, provide information in future public announcements regarding its outlook that may be of interest to the investment community. The format and extent of future outlooks may be different from the format and extent of the information contained in this release.
References by the Company to non-GAAP operating income and non-GAAP earnings per share refer to costs and expenses or earnings per share excluding equity-based compensation cost. GAAP requires that this cost be included in costs and expenses and accordingly used to determine operating income and earnings per share. The Company’s management uses non-GAAP operating income, and associated non-GAAP net income (which is the basis for non-GAAP earnings per share) to make operational and investment decisions, and the Company believes that they are among several useful measures for an enhanced understanding of its operating results. Excluding the equity compensation cost from GAAP operating income will enable investors to perform a meaningful comparison of the Company’s operating results to prior periods. In these prior periods, the Company’s GAAP financial results were not required to include expenses associated with stock option compensation, and now these expenses will be included within operating expenses in the GAAP presentation. The Company also believes that providing non-GAAP earnings per share affords investors a view of earnings that may be more easily compared to peer companies. The Company believes these non-GAAP measures will aid investors’ overall understanding of its financial results by providing a higher degree of transparency for certain expenses, particularly those related to equity-based compensation costs, as well as providing a level of disclosure that will help investors understand how the Company plans and measures its own business. However, non-GAAP net income should be construed neither as an alternative to GAAP net income or earnings per share as an indicator of its operating performance, nor as a substitute for cash flow from operations as a measure of liquidity, because the items excluded from the non-GAAP measures often have a material impact on the Company’s results of operations. Therefore, management does, and investors should, use non-GAAP measures in conjunction with the Company’s reported GAAP results.
