2 June 2025 - Singapore: Jadestone Energy plc (AIM:JSE) (the "Company" and together with its subsidiaries, "Jadestone" or the "Group"), an independent upstream production and development company focused on the Asia-Pacific region, announces the appointment of Thomas Mitchell (Mitch) Little as Chief Executive Officer ("CEO") effective 1 June 2025.

Mr. Little has relocated to Jadestone's head office in Singapore. Mr. Little will be responsible for the delivery of Jadestone's existing strategy, with the Group aiming to become the leading upstream independent in the Asia-Pacific region through both organic and inorganic growth.

Mr. Little has over 30 years of experience in the upstream oil and gas industry, the majority of which was with Marathon Oil Company ("Marathon") from 1987 to 2020 in various technical, supervisory and senior management positions.

Prior to leaving Marathon, Mr. Little was Executive Vice President: Operations, where he held full responsibility for all of Marathon's operations and development activities across US unconventional and international operations, including health and safety and global supply chain functions. He was also a member of Marathon's Executive Committee. His technical assignments included roles in operations, reservoir management and drilling throughout the U.S., offshore Norway, West Africa, North Africa, and Indonesia. He has a Bachelor of Science in Petroleum Engineering from the University of Wyoming.

Mr. Little also brings to Jadestone relevant industry expertise in his current role as Board Director of Helix Energy Solutions, a NYSE-listed international offshore energy services company that specializes in maximizing the output of existing oil and gas fields.

Dr. Adel Chaouch, Executive Chairman of Jadestone, commented:

"We are very pleased that Mitch is joining Jadestone as CEO. He brings significant upstream operational and management experience from over three decades in the oil and gas industry with Marathon.

His in-depth operational and technical knowledge across many jurisdictions, particularly in mature asset management, will be of particular benefit to Jadestone, as we seek to maximize the value of our existing operated positions in Australia, Indonesia and Malaysia and pursue further growth in these core areas. On behalf of everyone at Jadestone, we welcome Mitch to the business, and I look forward to working with him to execute our strategic aim to be the leading upstream independent in the Asia-Pacific region."

T. Mitch Little, Chief Executive Officer of Jadestone, commented:

"Jadestone has a very attractive platform of operated upstream positions in the Asia-Pacific region. This dynamic region will be at the forefront of global energy demand growth for the foreseeable future, and I'm confident that Jadestone is well positioned to contribute meaningfully to meeting the region's oil and gas demand growth in a safe and responsible manner.

I'm excited to relocate to the region and honoured to be joining the company at this stage of its development, as we work together to deliver on Jadestone's compelling strategy."

In connection with his appointment as CEO, the Company has awarded Mr. Little 1,142,648 restricted share units (equivalent to US$300,000) with a three-year vesting period.
