Item 3.01

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

On November 24, 2023, 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 previously announced resignation of Gary DiElsi from the Company’s Board of Directors (the “Board”) resulted in noncompliance with the board of directors independence requirements set forth in Nasdaq Listing Rule 5605(b)(1) and the requirement in Nasdaq Listing Rule 5605(c)(2)(A) to have an audit committee of at least three independent directors.

More specifically, when the Notice was issued, the Board did not have a majority of directors who would be considered “independent directors,” as that term is defined in Nasdaq Listing Rule 5605(a)(2) and the audit committee of the Board consisted of only two independent directors. Consistent with Nasdaq Listing Rules 5605(b)(1)(A) and Rule 5605(c)(4), Nasdaq has provided the Company a cure period in order to regain compliance (i) until the earlier of the Company’s next annual shareholders’ meeting or November 11, 2024, or (ii) if the next annual shareholders’ meeting is held before May 7, 2024, then the Company must evidence compliance no later than May 7, 2024.

The Notice has no immediate effect on the listing of the Company’s common stock on Nasdaq.
