This press release includes or incorporates by reference certain statements that constitute forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995.

These forward-looking statements are made based on management’s expectations and beliefs concerning future events affecting Orbotech and are subject to uncertainties and factors relating to Orbotech’s operations and business environment, all of which are difficult to predict and many of which are beyond the Company’s control. Many factors could cause the actual results to differ materially from those projected including, without limitation, cyclicality in the industries in which the Company operates, the Company’s

production capacity, timing and occurrence of product acceptance (the Company defines “bookings” and “backlog” as purchase arrangements with customers that are based on mutually agreed terms, which, in some cases for bookings and backlog, may still be subject to completion of written documentation and may be changed or cancelled by the customer, often without penalty), fluctuations in product mix, worldwide economic conditions generally, especially in the industries in which the Company operates, the timing and strength of product and service offerings by the Company and its competitors, changes in business or pricing strategies, changes in the prevailing political and regulatory framework in which the relevant parties operate or in economic or technological trends or conditions, including currency fluctuations, inflation and consumer confidence, on a global, regional or national basis, the level of consumer demand for sophisticated devices such as smartphones, tablets and other electronic devices as well as automobiles, the Company’s global operations and its ability to comply with varying legal, regulatory, exchange, tax and customs regimes, the Company’s ability to achieve strategic initiatives, including related to its acquisition strategy, the Company’s debt and corporate financing activities, the final timing and outcome (each, expected in mid-to-late 2016), and impact of the criminal matter and ongoing investigation in Korea, including any impact on existing or future business opportunities in Korea and elsewhere, any civil actions related to the Korean matter brought by third parties, including the Company’s customers, which may result in monetary judgments or settlements, expenses associated with the Korean matter, ongoing or increased hostilities in Israel and the surrounding areas, and other risks detailed in the Company’s SEC reports, including the Company’s Annual Report on Form 20-F for the year ended December 31, 2015, and subsequent SEC filings. As a result of all of the foregoing, the forward looking events discussed in this press release might not occur and our actual results may differ materially from those anticipated in the forward looking statements. Accordingly, you should not unduly rely on any forward looking statements. The Company assumes no obligation to update the information in this press release to reflect new information, future events or otherwise, except as required by law. New factors emerge from time to time, and it is not possible for us to predict all of these factors. Further, we cannot assess the impact of each such factor on our business or the extent to which any factor, or combination of factors, may cause actual results to be materially different from those contained in any forward looking statement.
