Grant of options

CAP-XX Limited (LON: CPX), a global leader in the design and manufacture of supercapacitors and energy management systems, announces a change to the structure of its Board of Directors.

After more than 12 years of service as Chairman, Pat Elliott has stepped down from that role but will remain as a Non-Executive Director. Dr. Graham Cooley, who has been a Non-Executive Director since June 2024, has assumed the role of Chairman.

This change reflects CAP-XX's decision to align the Board's leadership more closely with the Company's need for engagement with its shareholders. Dr. Cooley, who has extensive experience in the clean energy and advanced technology sectors, is based in the UK and will look to enhance communication and collaboration with investors and key stakeholders.

As part of his appointment as Chairman, Dr. Cooley has been granted 40,000,000 options (the "Options") over ordinary shares in the Company ("Ordinary Shares"), to further align his interests with those of shareholders as CAP-XX pursues its strategic objectives. The Options have an exercise price of 0.13p, being the closing mid-market price of an Ordinary share on 18 March 2025, the last practicable date prior to the grant of the Options. The five year options will vest immediately. Following this grant of Options, the total number of options outstanding over Ordinary Shares in the Company will be 264,165,000.

Pat Elliott commented: "It has been a tremendous privilege to serve as Chairman of CAP-XX for over a decade, guiding the Company through many phases of development. I am incredibly proud of what the team has accomplished and have every confidence that Graham's leadership will support our continued growth and success. I look forward to continuing to contribute as a Non-Executive Director."

Dr. Graham Cooley added: "I would like to sincerely thank Pat for his long-standing leadership and unwavering commitment to CAP-XX. His guidance has been instrumental in shaping the Company into the innovative business it is today. I am delighted to take on the role of Chairman and look forward to working with our CEO Lars Stegmann, the Board and management team to drive CAP-XX forward."
