| Item 3.01 | Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing. |
On August 8, 2025, ClearSign Technologies Corporation (the “Company”) received a notice (the “Notice”) from the Listing Qualifications Department of the Nasdaq Stock Market LLC (“Nasdaq”) stating that the Company is not in compliance with the board of directors independence requirement set forth in Nasdaq Listing Rule 5605(b)(1) and the audit committee composition requirement set forth in Nasdaq Listing Rule 5605(c)(2)(A) (collectively, the “Nasdaq Composition Requirements”) due to the resignations of Catharine M. de Lacy and Judith S. Schrecker (as described below) from the Company’s board of directors (the “Board”).
Specifically, when the Notice was issued, the Board did not have a majority of directors that would be considered “independent directors,” as that term is defined in Nasdaq Listing Rule 5605(a)(2), and the Audit and Risk Committee of the Board (the “Audit Committee”) consisted of only two independent directors, rather than the minimum three independent directors as required by Nasdaq Listing Rule 5605(c)(2)(A).
The Company intends to regain compliance with the Nasdaq Composition Requirements by appointing a new director to the Board and Audit Committee who meets the independence requirements under Nasdaq rules and Rule 10A-3(b)(1) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Consistent with Nasdaq Listing Rules 5605(b)(1)(A) and 5605(c)(4), Nasdaq has provided the Company a cure period in order to regain compliance with the Nasdaq Composition Requirements (i) until the earlier of the Company’s next annual meeting of stockholders or one year from the resignation of Mss. de Lacy and Schrecker, or August 4, 2026, or (ii) if the Company’s next annual meeting of stockholders is held before February 2, 2026, then no later than February 2, 2026.
The Notice has no immediate effect on the listing of the Company’s common stock on Nasdaq.
Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.
On August 4, 2025, Ms. de Lacy and Ms. Schrecker each notified the Company that they resigned from the Board, effective immediately. At the time of Ms. de Lacy’s resignation, she was a member of the Board, chairperson of the Nominating and Corporate Governance Committee of the Board (the “Governance Committee”) and a member of the Human Capital and Compensation Committee of the Board (the “Compensation Committee”). At the time of Ms. Schrecker’s resignation, she was a member of the Board, the lead independent director of the Board, chairperson of the Audit Committee, and a member of the Governance Committee and Compensation Committee. The decision by Mss. de Lacy and Schrecker to resign was not the result of any disagreement with the Company, known to an executive officer of the Company, on any matter relating to the Company’s operations, policies or practices.
In connection with the resignation of Mss. de Lacy and Schrecker, the Board decreased the number of directors from six to five on August 6, 2025, effective immediately. Further, on the same date, the Board appointed Louis J. Basenese, an independent director, to the Governance Committee and G. Todd Silva, an independent director, to the Compensation Committee, effective immediately. The Company does not currently intend to appoint a new lead independent director.
