Departure of Director

TotalEnergies Marketing Services SAS (“TEMS”), a wholly owned subsidiary of TotalEnergies SE, has decided to replace Laurent Wolffsheim, one of its director designees, with Mr. Mathieu Soulas, as described below. As such, on September 20, 2023, Mr. Wolffsheim resigned from the board of directors (“Board”) of Clean Energy Fuels Corp. (the “Company”), effective immediately. Mr. Wolffsheim’s resignation was not due to any disagreement with the Company on any matter relating to the Company’s operations, policies, or practices.

Appointment of New Director

On September 20, 2023, the Board filled the vacancy created by Mr. Wolffsheim’s resignation by appointing Mr. Soulas as a director of the Company, effective immediately. Mr. Soulas will not serve as a member of any committee of the Board.

Mr. Soulas has been appointed as a director of the Company pursuant to and in accordance with the director designation rights granted to TEMS in that certain Stock Purchase Agreement between the Company and TEMS, dated May 9, 2018, under which, among other things, TEMS purchased shares representing at the time 25% of the outstanding common stock of the Company, which represented the largest ownership position among shareholders of the Company. Such share purchase and the other transactions and relationships related thereto are described in further detail in Part II, Item 5 of the Company’s Quarterly Report on Form 10-Q, filed with the Securities and Exchange Commission (“SEC”) on May 10, 2018, and in the Company’s Current Report on Form 8-K, filed with the SEC on June 13, 2018, and the agreements related to such transactions are filed or incorporated by reference as exhibits to such reports. All such descriptions and agreements are incorporated herein by reference.

Mr. Soulas, 53, has served as Senior Vice President New Mobility and Marketing of TEMS since July 2023. Before that, Mr. Soulas was Vice President Strategy & Supply of the Marketing Services Branch since September 2021. Prior to that, he served as the Senior Vice President Strategy & Climate from 2017 to 2019 and Executive Vice President for the geographic zone of the Indian Ocean and Vice President Supply and Logistic for Africa & Middle East from 2013 to 2017. Mr. Soulas is a graduate of France’s Ecole Polytechnique and IFP-EN Engineering schools.

Mr. Soulas has voluntarily waived his right to receive compensation for his services as a director of the Company. As a result, the Company will not compensate Mr. Soulas pursuant to the Company’s compensation arrangements for its other non-employee directors, but rather will only reimburse Mr. Soulas for his reasonable out-of-pocket expenses.

The Company has entered into an indemnification agreement with Mr. Soulas in the same form as the indemnification agreements the Company has entered into with its other directors, which form has been filed or incorporated by reference as Exhibit 10.4 to the Company’s Registration Statement on Form S-1, filed with the SEC on March 27, 2007. In general, the indemnification agreement provides for, among other things, indemnification of each such person by the Company to the fullest extent authorized or permitted by law, subject to certain limited exceptions.

Except as set forth above, there are no arrangements or understandings between Mr. Soulas and any other person pursuant to which Mr. Soulas was selected as a director of the Company, there are no family relationships between Mr. Soulas and any of the Company’s other directors or executive officers, and Mr. Soulas is not a party to any transaction that would require disclosure under Item 404(a) of Regulation S-K promulgated by the SEC.

On September 21, 2023, the Company issued a press release announcing the changes to its Board described in Item 5.02 of this Current Report on Form 8-K. A copy of such press release is attached hereto as Exhibit 99.1.

As provided in General Instruction B.2 of Form 8-K, the information in this Item 7.01 of this Current Report on Form 8-K 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 it be incorporated by reference into any registration statement or other document filed under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
