Board Changes

London, 17 July 2023 - Serica Energy plc (AIM: SQZ), a British independent upstream oil and gas company, is delighted to announce that Kaat Van Hecke and Sian Lloyd Rees have each accepted an invitation to join Serica's Board as Independent Non-Executive Directors with immediate effect. Upon joining the Board, Kaat will be appointed to chair the HSE Committee and the Reserves Committee, and Sian will be joining the Remuneration and Sustainability Committees. After the AGM on 29 June 2023 Tony Craven Walker retired and David Latin took over as Chairman. The Company also announces that Trevor Garlick is stepping down as an Independent Non-Executive Director with effect from today's date.

Kaat has over 25 years of experience in the petrochemical and upstream oil and gas business. She has held a variety of positions with ExxonMobil, Shell, OMV, and Nostrum Oil & Gas in Europe, Nigeria, Russia and Kazakhstan. Kaat is an experienced Non-Executive Director who currently holds Independent Non-Executive Director positions and chairs Board Committees at Glover Gas & Power B.V/Axxela Limited, the largest private sector natural gas distributor in West Africa, and at Trinity Exploration & Production Plc which is focussed on Trinidad and Tobago.

Sian has over 30 years experience in Oil & Gas, IT and renewable Energy industries. Her career includes roles at Halliburton Corporation, Oracle Corporation and Aker Group, across multiple geographies. Currently Sian is UK Managing Director for Aker ASA's Mainstream Renewable Power business which is responsible for growing a renewable energy portfolio in offshore wind and hydrogen. She is also a Non-Executive Director and co-chair of OEUK Ltd, a Non-Executive Director for the UKs Net Zero Technology Centre Ltd, and a Non-Executive Director for Aberdeen Harbour Ltd (Port of Aberdeen).

David Latin, Chairman of Serica commented:

"Trevor Garlick joined the Board of Serica Energy plc just after the acquisition of the Bruce, Keith and Rhum assets was completed, he has chaired our Committees for HSE and Reserves throughout as well as sitting on other Board Committees, and we have benefited greatly from his broad understanding of our industry and his deep knowledge and experience of offshore production operations and reservoir management. We wish him all the very best for the future.

I am absolutely delighted to welcome Kaat Van Hecke and Sian Lloyd Rees to the Serica Energy plc Board following the recent retirements of Tony Craven Walker and Trevor Garlick. Kaat brings wide-ranging technical and operational experience in the exploration & production sector, from very large companies to small companies in multiple geographies, as a petroleum engineer, an executive leader and a Non-Executive Director. Sian augments and extends the overall experience set represented on the Board with her background in the supply chain, digital technology and the energy transition and brings perspectives gained as a Non-Executive Director for important industry funded government-facing organisations in the UK. I am very much looking forward to the contribution and support both Sian and Kaat will provide as we build on the strong financial and operating capabilities whch Serica has established whilst we continue to look at new opportunities to deliver growth for our shareholders."
