On November 7, 2025, Navitas Semiconductor Corporation (the “Company”) entered into a securities purchase agreement (the “Purchase Agreement”) with certain accredited investors (collectively, the “Purchasers”) for the issuance and sale in a private placement (the “Private Placement”) of an aggregate of 14,814,813 shares (the “Shares”) of Class A common stock of the Company, par value $0.0001 (the “Common Stock”), at a purchase price of $6.75 per share. The Private Placement closed on November 10, 2025. The Purchase Agreement contains customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company and the Purchasers, including for liabilities under the Securities Act of 1933, as amended (the “Securities Act”).

In connection with the Private Placement, the Company entered into a registration rights agreement (the “Registration Rights Agreement”), dated as of November 7, 2025, with the Purchasers, pursuant to which the Company agreed to prepare and file a registration statement with the Securities and Exchange Commission (the “SEC”) registering the resale of the Shares no later than November 17, 2025, and to use commercially reasonable efforts to have the registration statement declared effective as promptly as practical thereafter, and in any event no later than 120 days following the date of the Registration Rights Agreement in the event of a “full review” by the SEC.

The gross proceeds to the Company from the Private Placement were approximately $100 million, before deducting placement agent fees and expenses and estimated offering expenses payable by the Company.
