Forward-Looking Statements

This press release contains, and the discussions in our subsequent conference call will contain, forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. These statements include: (i) the company’s intention to create additional operating leverage from investments in the business; (ii) any anticipation or guidance as to future financial performance, including future revenue, gross margin, operating expense, operating margin, EBITDA, free cash flow and other financial metrics; and (iii) the Company's beliefs regarding the purpose, usefulness and efficacy of non-GAAP results and the measures and items the Company includes in the same, as well as any benefits to investors the Company believes its non-GAAP measures provide.  These forward-looking statements involve risks and uncertainties that could cause actual results to differ materially from those projected.  In particular, the Company's ability to predict future financial performance continues to be difficult due to, among other things:  (a) continuing general limited visibility across many of our product lines; (b) the ongoing potential for significant quarter-over-quarter product mix fluctuations, which can materially impact profitability due to the broad gross margin range across our portfolio; (c) continuing consolidation activities affecting our customer base, which limits demand visibility in the short term, and could reduce our business potential in the long term; (d) average selling prices continue to decline across our traditional Optical Communications and our Advanced Optical Technologies and Commercial Lasers businesses; (e) we and many of our suppliers continue to experience execution and delivery challenges which limit our revenue and impair our profitability; (f) our Communications Test and Measurement business is notable for seasonality and a significant level of in-quarter book-and-ship business, further limiting our forecasting abilities; (g) we are currently engaged in various product and manufacturing transfers and site consolidations as well as material IT and system infrastructure upgrades, which may cause interim increases in expenses, execution disruptions, customer satisfaction issues and quality and delivery problems; and (h) the current general economic uncertainty is further limiting our visibility in the near-term and may have a material adverse impact on our business.
