On October 16, 2025, the Board of Directors (the “Board”) of Liberty Energy Inc. (the “Company”) appointed Ms. Alice Yake (Jackson) to an existing Class II vacancy on the Board. Ms. Yake will serve a term expiring at the Company’s 2027 annual meeting of stockholders. The Board has not determined the committees of the Board, if any, to which Ms. Yake may be appointed. The appointment of Ms. Yake to the Board was based upon the recommendation of the Board’s Nominating and Governance Committee. The Board determined that Ms. Yake is independent under New York Stock Exchange rules.

As compensation for her service on the Board, Ms. Yake will participate in the Company’s standard non-employee director compensation program, prorated to reflect her partial year of service in 2025, which program is more fully described under the caption “Director Compensation” in the Company’s definitive proxy statement on Schedule 14A filed with the Securities and Exchange Commission (the “SEC”) on March 6, 2025, as may be amended from time to time.

Ms. Yake does not have any family relationships with any director, executive officer, or person nominated or chosen to become a director or executive officer of the Company, and there are no arrangements or understandings between her and any other person pursuant to which Ms. Yake was selected as a director of the Company. Since the beginning of the Company’s last fiscal year, neither Ms. Yake nor her immediate family members have had any direct or indirect material interest in any existing or proposed transaction, arrangement, or relationship with the Company or any director or executive officer of the Company or immediate family member thereof in which the amount involved exceeds $120,000.

The Company expects to enter into an indemnification agreement with Ms. Yake substantially in the form that was previously filed as Exhibit 10.24 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, as filed with the SEC on February 6, 2025, and is incorporated by reference herein.
