Item 3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing

On April 28, 2025, Complete Solaria, Inc. (the “Company”) received an expected letter from the Listing Qualifications staff of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that, as a result of the Company’s delay in filing its Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”), the Company was not in compliance with the timely filing requirements for continued listing under Nasdaq Listing Rule 5250(c)(1).

The Nasdaq letter has no immediate effect on the listing or trading of the Company’s common stock or warrants.

The Company’s Form 12b-25 Notification of Late Filing (the “Form 12b-25”) filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2025 indicated that the filing of the 2024 Form 10-K was delayed because the Company required more time to complete the procedures relating to its year-end reporting process. The Company issued a further press release on April 19, 2025 stating its plan to file the 2024 Form 10-K on April 30, 2025. Subsequently, the Company filed the 2024 Form 10-K on April 30, 2025.

The Nasdaq listing rules require Nasdaq-listed companies to timely file all required periodic reports with the SEC. The Nasdaq letter stated that, under Nasdaq rules, the Company had 60 calendar days to submit a plan to regain compliance with Nasdaq’s continued listing requirements.

Item 7.01. Regulation FD Disclosure.

On May 2, 2025, the Company issued a press release disclosing the Company’s receipt of the Nasdaq notification letter. A copy of the press release is attached as Exhibit 99.1 hereto and incorporated herein by reference.

In accordance with General Instruction B.2 of Form 8-K, the information furnished under this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall such information be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended, or the Exchange Act except as shall be expressly set forth by specific reference in such a filing.

Item 9.01. Financial Statements and Exhibits.
