Forward-looking statements may be identified by the use of words such as “estimate,” “plan,” “project,” “forecast,” “intend,” “expect,” “anticipate,” “believe,” “seek,” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunity and market share. These statements are based on various assumptions, whether or not identified in this Presentation, and on the current expectations of management of Navitas Semiconductor Limited (“Navitas” or the “Company”) and Live Oak Acquisition Corp. II (“LOKB”) 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 Navitas and LOKB. These forward-looking statements are subject to a number of risks and uncertainties, including the possibility that the expected growth of Navitas’ business will not be realized, or will not be realized within the expected time period, due to, among other things: Navitas’ goals and strategies, future business development, financial condition and results of operations; Navitas’ customer relationships and ability to retain and expand these customer relationships; Navitas’ ability to accurately predict future revenues for the purpose of appropriately budgeting and adjusting Navitas’ expenses; Navitas’ ability to diversify its customer base and develop relationships in new markets; the level of demand in Navitas’ customers’ end markets; Navitas’ ability to attract, train and retain key qualified personnel; changes in trade policies, including the imposition of tariffs; the impact of the COVID-19 pandemic on Navitas’ business, results of operations and financial condition; the impact of the COVID-19 pandemic on the global economy; the ability of Navitas to maintain compliance with certain U.S. Government contracting requirements; regulatory developments in the United States and foreign countries; and Navitas’ ability to protect its intellectual property rights.
