Mr. Rodriguez, 40, mostly recently served as Chief Financial Officer and Treasurer of Aspen Aerogels, Inc., a public advanced materials company, from April 2022, and as Chief Strategy Officer from November 2021 to April 2022. Prior to that, from February 2019 to November 2021, he was a Corporate Strategy Director at Aptiv, a $15 billion automotive technology company, where he led the establishment of its Vehicle Electrification Systems group, among other value-adding initiatives. From April 2010 to February 2019, he served in a variety of finance, planning and other leadership roles at ClearMotion, a developer of active suspension technology, General Motors’ OnStar division, an in-vehicle safety and security system, Amazon and Fiat Chrysler Automobiles (now Stellantis). In addition, Mr. Rodriguez worked as an investment banker at Lazard, a financial advisory firm, where he focused on automotive mergers and acquisition and restructuring advisory services. Mr. Rodriguez received his Bachelor of Science degree in Mechanical Engineering from General Motors Institute / Kettering University while working at Magna International and holds an MBA from Harvard Business School.

The Company entered into an employment offer letter with Mr. Rodriguez (the "Offer Letter") which sets forth the terms of his employment and compensation. The Offer Letter provides that Mr. Rodriguez's employment is at-will and may be terminated by either Mr. Rodriguez or the Company at any time and for any reason. Pursuant to the Offer Letter, Mr. Rodriguez will receive an annual base salary of $451,000 and, beginning in 2026, he will be eligible to earn an annual cash bonus with a target value equal to 65% of his annual base salary, based on the achievement of performance goals established by the Board of Directors of the Company (the “Board”) and/or the compensation committee of the Board (the "Compensation Committee") in its sole discretion. Mr. Rodriguez is also eligible to receive a one-time sign-on bonus of $80,000, subject to repayment upon a voluntary termination of employment at any time during the first 12 months of employment. In addition, Mr. Rodriguez is entitled to direct payment or reimbursement by the Company for certain tuition expenses and up to $50,000 for temporary housing and relocation benefits in connection with the relocation of his primary residence to the San Francisco area, subject to repayment upon a voluntary termination at any time during the first 12 months of employment.

Pursuant to the Offer letter and in connection with his appointment as Chief Financial Officer, the Compensation Committee approved a grant to Mr. Rodriguez of an award of 200,000 restricted stock units, with a grant date of October 6, 2025, covering shares of the Company's common stock pursuant to the Company's 2022 Equity Incentive Plan and a grant agreement entered into between the Company and Mr. Rodriguez. The award will vest as to 25% of the total number of restricted stock units granted on the first Quarterly Vesting Date (as defined in the Offer Letter) on or immediately following the one-year anniversary of his start date, and the remainder will vest quarterly over three years thereafter, subject to Mr. Rodriguez's continuous employment with the Company on each applicable vesting date. In addition, Mr. Rodriguez will be eligible to receive additional grants of equity awards as determined in the sole discretion of the Board or the Compensation Committee pursuant to the Company’s policies as in effect from time to time.

Pursuant to the Offer Letter, if Mr. Rodriguez's employment is terminated by the Company other than for Cause (as defined in the Offer Letter), death or disability or by Mr. Rodriguez for Good Reason (as defined in the Offer Letter), in either case, then Mr. Rodriguez will be eligible to receive severance benefits in the form of base salary continuation for a period of three months following the date of termination subject to his execution of an effective and irrevocable release of claims.

Except for the Offer Letter, the selection of Mr. Rodriguez was not pursuant to any arrangement or understanding between him and any other person. There have been no transactions since the beginning of the Company’s last fiscal year, and there are no currently proposed transactions, in which the Company was or is to be a participant and in which Mr. Rodriguez or any member of his immediate family had or will have any material interest that are required to be reported under Item 404(a) of Regulation S-K.

Mr. Rodriguez has entered into the Company’s form of indemnification agreement, which, among other things, requires the Company to indemnify Mr. Rodriguez for certain expenses, including attorneys’ fees, judgments, fines and settlement amounts incurred by him in any action or proceeding arising out of his services as an executive officer or as a director of any other company or enterprise to which he provides services at the Company’s request.

The foregoing description is qualified in its entirety by reference to the full text of the form of indemnification agreement, which is filed as Exhibit 10.12 to the Company’s Registration Statement on Form S-4 filed with the SEC on August 9, 2022 and incorporated herein by reference.
