FORWARD-LOOKING STATEMENTS
This presentation includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. 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. These statements are also based on current expectations of the management of Navitas Semiconductor Corporation (formerly known as Live Oak Acquisition Corp. II) (“Navitas” or the “Company”) and are not predictions of actual performance. Such 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 and expectations. Many actual events and circumstances that affect performance are beyond the control of Navitas. 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 and its ability to achieve and implement them, the success or failure of current or future business development efforts; Navitas’ 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; Navitas’ ability to scale its technology into new markets and applications; the effects of competition on Navitas’ business, including actions of competitors with an established presence and resources in markets we hope to penetrate; the level of demand in Navitas’ customers’ end markets, both generally and with respect to successive generations of products or technology; Navitas’ ability to attract, train and retain key qualified personnel; changes in government 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, including but not limited to Navitas’ supply chain and the supply chains of customers and suppliers; the ability of Navitas to maintain compliance with certain U.S. Government contracting requirements; regulatory developments in the United States and foreign countries; Navitas’ ability to protect its intellectual property rights; and the risk of inadvertently infringing the intellectual property rights of others. These and other risk factors are discussed in more detail in filings we make with the Securities and Exchange Commission (“SEC”), including, for example, the Risk Factors section beginning on p. 6 of the prospectus dated December 6, 2021, which we filed with the SEC on December 7, 2021, as supplemented or amended from time to time, as well as in other SEC filings. 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 Navitas is not aware of or that Navitas currently believes are immaterial that could also cause actual results to differ materially from those contained in the forward-looking statements. In addition, forward-looking statements reflect Navitas’ expectations, plans or forecasts of future events and views as of the date of this presentation. Navitas anticipates that subsequent events and developments will cause Navitas’ assessments to change. However, while Navitas may elect to update our forward-looking statements at some point in the future, Navitas specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing Navitas’ assessments as of any date subsequent to the date of this presentation. Accordingly, undue reliance should not be placed upon our forward-looking statements. Neither Navitas nor any of its affiliates have any obligation to update this presentation.

USE OF PROJECTIONS
This presentation contains projected financial information with respect to Navitas. Such projected financial information constitutes forward-looking information, is for illustrative purposes only and should not be relied upon as necessarily being indicative of future results. The assumptions and estimates underlying such projected financial information are inherently uncertain and are subject to a wide variety of significant business, economic, competitive and other risks and uncertainties that could cause actual results to differ materially from those contained in the projected financial information. See the cautions included in the “Forward-Looking Statements” paragraph above. Actual results may differ materially from the results contemplated by the projected financial information contained in this presentation, and the inclusion of such information in this presentation should not be regarded as a representation by any person that the results reflected in such information will be achieved. Navitas’ independent registered public accounting firm has not audited, reviewed, compiled or performed any procedures with respect to such projections for the purpose of their inclusion in this presentation, and accordingly has not expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation.

IMPORTANT INFORMATION AND WHERE TO FIND IT
Navitas files quarterly, annual and periodic reports as well as other information with the U.S. Securities and Exchange Commission (“SEC”), which are available at Navitas’ Investor Relations website at https://ir.navitassemi.com/ or at the SEC’s website at https://www.sec.gov. You can find a description of risks affecting Navitas and its business in the Risk Factors section beginning on p. 6 of the prospectus dated December 6, 2021, which we filed with the SEC on December 7, 2021, as supplemented or amended from time to time, and in other filings we make with the SEC.

FINANCIAL INFORMATION; NON-GAAP FINANCIAL MEASURES
This presentation includes financial information and data which are unaudited and do not conform to Regulation S-X promulgated under the Securities Act of 1933, as amended. Accordingly, such information and data may not be included in, may be adjusted in or may be presented differently in, any proxy statement, prospectus, registration statement or other filing which has been filed or is to be filed by Navitas with the SEC. In addition, some of the financial information and data contained in this presentation, such as EBITDA, have not been prepared in accordance with United States generally accepted accounting principles (“GAAP”), which we refer to as “non-GAAP financial measures.” Navitas believes these non-GAAP financial measures provide useful information to management and investors regarding certain financial and business trends relating to Navitas’ financial condition and results of operations. Navitas believes that the use of these non-GAAP financial measures provides an additional tool for investors to use, together with GAAP measures that we also provide, in evaluating projected operating results and trends, and in comparing Navitas’ financial measures with other similar companies, many of which present similar non-GAAP financial measures to investors. Management does not consider these non-GAAP financial measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in Navitas’ financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non-GAAP financial measures. And, because non-GAAP financial measures are not standardized, it may not be possible to compare non-GAAP financial measures prepared by Navitas with non-GAAP financial measures prepared by other companies, even if the measures have similar names.

INDUSTRY AND MARKET DATA
This presentation relies on and refers to information and statistics regarding the sectors in which Navitas competes and other industry data. This information and statistics were obtained from third party sources, including reports by market research firms. Although Navitas believes these sources to be reliable, it has not independently verified the information and does not guarantee its accuracy and completeness. This information has been supplemented in certain cases with information from discussions with Navitas’ customers and internal estimates, taking into account publicly available information about other industry participants and Navitas’ management’s best view as to information that is not publicly available. This presentation contains preliminary information only, is subject to change at any time and is not, and should not be assumed to be, complete or to constitute all the information necessary to adequately make an informed decision regarding Navitas.
