DEREGISTRATION OF SECURITIES

On August 27, 2025, Aptera Motors Corp. (the “Company”) filed with the Securities and Exchange Commission (the “SEC”) a registration statement on Form S-1 (File No. 333-289898), which was originally declared effective by the SEC on September 30, 2025 (the “Registration Statement”). The Registration Statement registered the resale of 31,741,948 shares of Class B common stock of the Company by the registered stockholders identified in the prospectus included in the Registration Statement. As disclosed in the Registration Statement, the Company intended to maintain the effectiveness of the Registration Statement for 90 days. Such 90-day period has lapsed, during which the Company has been subject to the reporting requirements of Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as amended. Accordingly, the “current public information” requirements of Rule 144 under the Securities Act of 1933, as amended (“Rule 144”), have been satisfied as of the date hereof and, subject to compliance with the other provisions of Rule 144, the registered stockholders may be able to sell their shares pursuant to Rule 144.

In accordance with an undertaking made by the Company in the Registration Statement to remove by means of a post-effective amendment any of the securities registered which remain unsold at the termination of the offering, this Post-Effective Amendment No. 1 to the Registration Statement is being filed to terminate the effectiveness of the Registration Statement and to remove from registration all securities registered but not sold under the Registration Statement.
