Item 1.01. Entry into a Material Definitive Agreement. On September 18, 2026, Navitas Semiconductor Corporation (the “Company”) entered into a Stock Purchase Agreement (the “Purchase Agreement”) with Magnachip Semiconductor Corporation (“Magnachip”), pursuant to which Magnachip agreed to issue and sell to the Company 1,461,988 shares of Magnachip’s common stock, par value $0.01 per share (the “MX Common Stock”), at a purchase price of $3.42 per share, for an aggregate purchase price of $5,000,000. The closing of the transactions contemplated by the Purchase Agreement is expected to occur on or about September 24, 2026, subject to the satisfaction or waiver of customary closing conditions. The Purchase Agreement contains customary representations, warranties and covenants, which were made only for purposes of the Purchase Agreement and as of specific dates, were solely for the benefit of the parties to the Purchase Agreement, and may be subject to limitations agreed upon by the Company and Magnachip. The Purchase Agreement also provides that Magnachip will file with the Securities and Exchange Commission (the “SEC”), no later than 30 days after the closing, a registration statement on Form S-3 covering the resale of the shares of MX Common Stock issued in the transaction. Magnachip agreed to use commercially reasonable efforts to cause the registration statement to become effective within 60 days following the closing or 90 days following closing if the SEC reviews the registration statement, or, if earlier, by the fifth (5th) business day after the SEC notifies Magnachip that the registration statement will not be reviewed or is no longer subject to further review and comments. Subject to the resale registration rights described in the previous paragraph, the shares of MX Common Stock issuable pursuant to the Purchase Agreement will not be registered under the Securities Act of 1933, as amended (the “Securities Act”), and will be issued in reliance on the exemption from registration requirements thereof provided by Section 4(a)(2) of the Securities Act or Rule 506 of Regulation D promulgated thereunder. The Purchase Agreement is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference. The summary description of the Purchase Agreement in this Current Report on Form 8-K does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase Agreement.
