ZION OIL & GAS INC

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers. On May 28, 2026, memorial services will be held for Mr. John Brown, Executive Chairman of the Board of Directors of Zion Oil and Gas, Inc., ("Zion" or the "Company") at the Mulkey-Bowles-Montgomery Funeral Home in Denton, Texas. John passed away peacefully on May 22, 2026, in his home at the age of 86. John was Founder and Chairman of Zion, which since its inception has been and continues to faithfully pursue John's vision for the discovery and development of oil and gas reserves in Israel for the benefit of the land and its people. John Brown held a BBA degree from Fullerton College. He was awarded a degree in Doctor of Biblical Studies in 2013 from Emmanuel Baptist University. Mr. Brown’s senior management experience as well as his extensive experience in the oil and gas sector in the State of Israel provided to him the insight and vision needed to lead the Company as its founder. Recognizing and acknowledging that the mission of Zion could not rest on one man's shoulders, John and Zion's Board of Directors (the "Board") designed and implemented a plan of succession led by Robert W. A. Dunn, Zion's Chief Executive Officer, and Michael B. Croswell, Jr., Zion's President and Chief Financial Officer, both of whom are approximately fifty (50) years of age. Confident in the Company's management and its ability to lead the Company forward and fulfill his original vision, John had plans to retire as Zion's Executive Chairman of the Board at Zion's annual shareholders' meeting June 2, 2026.
