Halliburton Co

Item 5.02 . Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers .

On October 15, 2026, the Board of Directors (the "Board") of Halliburton Company ("Halliburton") appointed David C. Hernandez as a member of the Board to fill a vacancy. The size of the Board remains at 12 directors. Mr. Hernandez currently serves as President and Director of Hunt Consolidated, Inc. ("Hunt Consolidated"). Mr. Hernandez brings extensive C-suite leadership experience across energy and industrial businesses, including expertise in corporate strategy, capital allocation, financial oversight, enterprise risk management, regulatory compliance, and governance. Mr. Hernandez has served as President of Hunt Consolidated since 2025, and during 2019-2022. In addition, during 2023-2024 he served as Chairman and Managing Director of Hunt Consolidated. Prior to joining Hunt Consolidated, Mr. Hernandez served as Vice President of Tax for Electronic Data Systems. Mr. Hernandez earned a J.D. from The University of Chicago and a Bachelor of Science in Finance from the University of Virginia McIntire School of Commerce.

Mr. Hernandez will participate in the compensation arrangements for non-management directors as described in Halliburton's Definitive Proxy Statement on Schedule 14A for Halliburton's 2026 Annual Meeting of Shareholders filed with the SEC on March 31, 2026. Mr. Hernandez will receive an initial equity award of restricted stock units ("RSUs") equal to the prorated value of the annual equity award of $200,000 granted to Halliburton's non-management Directors. Each RSU represents the right to receive a share of Halliburton's common stock on a future date as provided in the award agreement. The factor used to determine the prorated award is the number of whole months of service from the beginning of the month in which the Board service begins to the following first of December divided by twelve. The number of RSUs awarded is determined by dividing the prorated award amount by the average of the closing prices of Halliburton's common stock on the New York Stock Exchange on each business day during the full calendar month immediately preceding the date Mr. Hernandez joined the Board. Based on this formula, Mr. Hernandez will receive an initial award of 961 RSUs.

In connection with Mr. Hernandez's appointment, Halliburton entered into an indemnification agreement with Mr. Hernandez on October 15, 2026. The indemnification agreement provides that, subject to certain exceptions and limitations set forth therein, Halliburton will indemnify and advance certain expenses to Mr. Hernandez to the fullest extent, and only to the extent, permitted by applicable law in effect as of the date of the indemnification agreement and to such greater extent as applicable law may thereafter from time to time permit. The foregoing description of the indemnification agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Form of Indemnification Agreement for Directors, a copy of which is incorporated by reference as Exhibit 10.1 to this Current Report on Form 8-K.
