Board Changes

Seascape Energy, an E&P company focused on Southeast Asia, is pleased to announce the appointment of Michael (Mike) J Buck as an Independent Non-executive Director, supporting the Company's next phase of growth and increasing operational focus.

Mike has over 40 years' experience in the oil & gas industry having spent 20 years with UK Independent LASMO plc and being involved in the discovery & development of several commercial oil & gas fields in the UK, Indonesia, Colombia and Libya. Subsequently with ENI, Mike was appointed Managing Director of the Major's operations in Pakistan and then Iran, working on major oil and gas developments in both countries.

Mike joined Southeast Asian-focused Salamander Energy plc as Chief Operating Officer overseeing the operational side of the business and helping it grow to over 14,000 boepd of production through the development of several onshore and offshore oil & gas fields in Indonesia and Thailand. Since 2017, Mike has been the Chief Executive Officer at Petro Matad which has successfully drilled eight wells in Mongolia and recently brought into production two discoveries in Block XX despite challenging operating conditions.

Mike holds a BSc in Geophysics from Liverpool University and an MSc (with Distinction) in Petroleum Geology from Imperial College, London.

To ensure Seascape's board remains commensurate with its current size, Graham Stewart has notified Seascape of his intention to not seek re-election to the Board of Directors at the Company's AGM in June 2026. Graham has served on the Board of Seascape and its predecessor company, Longboat Energy, since its IPO in November 2019 originally acting as Non-Executive Chairman until mid-2024 coinciding with the Company's successful pivot to Southeast Asia.

James Menzies, Executive Chairman of Seascape Energy Asia plc commented:

"Having successfully put together a small but high-quality portfolio of assets in Malaysia, Seascape is quickly evolving into an operational Company.

I have known Mike for over 20 years and believe his skill set will significantly contribute to the Company's success and I look forward to working with him again to build an exciting business in the Southeast Asian E&P space.

I also want to thank Graham for his wise counsel in the boardroom and the instrumental role he played bringing about a successful pivot to Southeast Asia and subsequent board continuity. He will be missed and we wish him continued success with his other business interests."
