Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangement of Certain Officers.
On August 19, 2026, Kwaku Temeng verbally notified the Board of Directors of Core Laboratories Inc. (the “Company”) of his intention to resign as a director of the Company effective October 1, 2026. Subsequently, on August 25, 2026, Mr. Temeng confirmed his resignation by letter addressed to the Board of Directors. Mr. Temeng serves as Chairman of the Nominating Committee and as a member of the Compensation Committee.
As stated in his letter, Mr. Temeng’s resignation was due to a disagreement with the Board of Directors regarding the strategic direction of the Company and certain governance practices.
The Board of Directors believes that Mr. Temeng’s primary disagreement involves the manner in which the Company is conducting succession planning within the organization, a process supported by a majority of the members of the Board. With respect to strategic direction, the Board of Directors believes Mr. Temeng has concerns with the Company’s research priorities.
A copy of Mr. Temeng’s resignation letter to the Board of Directors is filed as Exhibit 17.1 to this Form 8-K. The Company provided Mr. Temeng with a copy of this Form 8-K and an opportunity to state whether he agrees with the statements herein and, if not, the respects in which he disagrees.
Throughout his more than five years of service on the Board, the Company has appreciated Mr. Temeng’s contributions, commitment and leadership.
