Exhibit 99.1

Navitas Semiconductor, the Industry Leader in Gallium Nitride (GaN) Power ICs,

Announces Third Quarter 2021 Financial Results

EL SEGUNDO, CALIF., November 9, 2021— Navitas Semiconductor Corporation (the “Company” or “Navitas”) (Nasdaq: NVTS and NVTSW), the industry leader in GaN Power ICs, today announced financial results for the third quarter ended September 30, 2021.

Net revenues for the third quarter of 2021 were $5.6 million, up 61 percent from the third quarter of 2020. Revenues for the first nine months of 2021 increased 128% over the same period in 2020. GAAP net loss for the third quarter of 2021 was $9.5 million, or $0.57 per share, compared to a GAAP net loss of $4.1 million, or $0.27 per share in the third quarter of 2020. On a non-GAAP basis, net loss for the third quarter of 2021 was $6.6 million, or $0.39 per share, compared to a non-GAAP net loss of $3.8 million, or $0.26 per share, in the third quarter of 2020.

“Worldwide GaN penetration in the $2B fast charger market is estimated at only 2-3% so far, so we expect a fast revenue ramp ahead in mobile plus the higher-power expansion markets of data center, solar and EV,” said Gene Sheridan, co-founder and CEO. “Couple that with next-gen technology introductions, growing team strength and more than 130 patents issued or pending, and we have an extraordinary opportunity in front of us to become the next-generation power semiconductor leader.”

Non-GAAP Financial Measures

This press release includes financial measures that are not calculated in accordance with generally accepted accounting principles (“GAAP”), which we refer to as “non-GAAP financial measures”, including (i) non-GAAP gross profit and the related non-GAAP gross margin and (ii) non-GAAP operating expenses. Each of these non-GAAP financial measures is adjusted from GAAP results to exclude certain expenses, which are outlined in the “Reconciliation of GAAP to Non-GAAP Financial Measures” tables below. We believe these non-GAAP financial measures provide investors with useful supplemental information about our operating performance and enable comparison of financial trends and results between periods where certain items may vary independent of business performance. We believe these non-GAAP financial measures offer an additional view of our operations that, when coupled with the GAAP results and the reconciliations to corresponding GAAP financial measures, provide a more complete understanding of the results of operations. However, these non-GAAP financial measures should be considered as a supplement to, and not as a substitute for, or superior to, the corresponding measures calculated in accordance with GAAP.

Cautionary Statement Regarding Forward-Looking Statements

This press release, including the paragraph headed “Business Outlook”, includes “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements may be identified by the use of words such as “we expect” or “are expected

to be”, “estimate,” “plan,” “project,” “forecast,” “intend,” “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 press release. These statements are also based on current expectations of the management of Navitas 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 of 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; and Navitas’ ability to protect its intellectual property rights. Forward-looking statements are also subject to additional risks and uncertainties, including changes in domestic and foreign business, market, financial, political and legal conditions; failure to realize anticipated benefits from Navitas’ recently completed business combination with Live Oak Acquisition Corp. II (“LOKB”); risks relating to the uncertainty of projected financial information with respect to Navitas; risks related to the rollout of Navitas’ business and the timing of expected business milestones; and other factors discussed in the proxy statement/prospectus filed by LOKB with the Securities and Exchange Commission (the “SEC”) on September 20, 2021 under the heading “Risk Factors—Risks Related to Navitas’ Business,” and other documents of LOKB or the Company 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 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 press release. Navitas anticipates that subsequent events and developments will cause Navitas’ assessments to change. However, while Navitas may elect to update these 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 press release. Accordingly, undue reliance should not be placed upon the forward-looking statements.
