Forward-Looking Statements

“Safe Harbor” Statement Under U.S. Private Securities Litigation Reform Act of 1995

This press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These statements include: (1) our optimism about our ability to extend our track record of success in fiscal 2023 and beyond; and (2) all of the statements under the “Business Outlook” section regarding our expected revenue, GAAP and non-GAAP net income per share, and fully diluted shares outstanding for the first quarter of fiscal year 2023. These forward-looking statements involve risks and uncertainties, and actual results could vary materially from these forward-looking statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to: the effects of the COVID-19 pandemic on our business, particularly the possibility of (1) the growing global economic downturn, (2) extended shutdowns at any of our manufacturing facilities, especially if the pandemic intensifies or returns in various geographic areas, (3) continued disruption to our supply chain, which could increase our costs and affect our ability to procure parts and materials, especially if the pandemic intensifies or returns in various geographic areas, and (4) regional downward demand adjustments from our customers, particularly those in areas affected by the pandemic; less customer demand for our products and services than forecasted; less growth in the optical communications, industrial lasers and sensors markets than we forecast; difficulties expanding into additional markets, such as the semiconductor processing, biotechnology, metrology and materials processing markets; increased competition in the optical manufacturing services markets; difficulties in delivering products and services that compete effectively from a price and performance perspective; our reliance on a small number of customers and suppliers; difficulties in managing our operating costs; difficulties in managing and operating our business across multiple countries (including Thailand, the People’s Republic of China, Israel, the U.S. and the U.K.); and other important factors as described in reports and documents we file from time to time with the Securities and Exchange Commission (SEC), including the factors described under the section captioned “Risk Factors” in our Quarterly Report on Form 10-Q filed with the SEC on May 3, 2022. We disclaim any obligation to update information contained in these forward-looking statements whether as a result of new information, future events, or otherwise.

Use of Non-GAAP Financials

We refer to the non-GAAP financial measures cited above in making operating decisions because they provide meaningful supplemental information regarding our ongoing operational performance. Non-GAAP net income excludes: share-based compensation expenses; depreciation of fair value uplift; amortization of intangibles; severance payment and others; other expenses in relation to reduction in workforce; and amortization of deferred debt issuance costs. We have excluded these items in order to enhance investors’ understanding of our underlying operations. The use of these non-GAAP financial measures has material limitations because they should not be used to evaluate our company without reference to their corresponding GAAP financial measures. As such, we compensate for these material limitations by using these non-GAAP financial measures in conjunction with GAAP financial measures.

These non-GAAP financial measures are used to: (1) measure company performance against historical results, (2) facilitate comparisons to our competitors’ operating results, and (3) allow greater transparency with respect to information used by management in making financial and operational decisions. In addition, these non-GAAP financial measures are used to measure company performance for the purposes of determining employee incentive plan compensation.
