These forward-looking statements include, but are not limited to, statements regarding the anticipated transaction and future economic and market conditions. These statements are based on various assumptions, whether or not identified in this press release, and on the current expectations of Valens’ and PTK’s management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Valens and PTK. These forward-looking statements are subject to a number of risks and uncertainties, including changes in domestic and foreign business, market, financial, political and legal conditions; the inability of the parties to successfully or timely consummate the proposed business combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the proposed business combination or that the approval of the shareholders of PTK or Valens is not obtained; failure to realize the anticipated benefits of the proposed business combination; risks relating to the uncertainty of the projected financial information with respect to Valens; future global, regional or local economic and market conditions; the development, effects and enforcement of laws and regulations; Valens’ ability to manage future growth; Valens’ ability to develop new products and solutions, bring them to market in a timely manner, and make enhancements to them; the effects of competition on Valens’ future business; the amount of redemption requests made by PTK’s public shareholders; the ability of PTK or the combined company to issue equity or equity-linked securities in connection with the proposed business combination or in the future; the outcome of any potential litigation, government and regulatory proceedings, investigations and inquiries; the effects of health epidemics, such as the recent global COVID-19 pandemic, have had and could in the future have on Valens’ revenue, its employees and results of operations; the cyclicality of the semiconductor industry; Valens’ ability to adjust its supply chain volume due to changing market conditions or failure to estimate its customers’ demand, including during any downturn in the automotive or audio-video markets; disruptions in relationships with any one of Valens’ key customers; difficulty selling products if customers do not design Valens products into their product offerings; Valens’ dependence on winning selection processes and ability to generate timely or sufficient net sales or margins from those wins; political conditions in Israel; and those factors discussed in PTK’s 10-K filed with the SEC on April 1, 2021 under the heading “Risk Factors,” and other documents of PTK filed, or to be filed, with the SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Valens nor PTK presently know or that Valens and PTK currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Valens’ and PTK’s expectations, plans or forecasts of future events and views as of the date of this press release. Valens and PTK anticipate that subsequent events and developments will cause Valens’ and PTK’s assessments to change.
