Notes to Editors

Serica Energy is an independent British oil and gas company with a broad portfolio of assets located in the UK Continental Shelf (UKCS). The Company is responsible for about 5% of the UK's natural gas, which plays a significant role in supporting the country's energy transition, and has invested over £1 billion in the UK supply chain since 2020. Serica maintains a balanced output of oil and gas across its operations.

The Company's key producing assets are grouped around two major hubs: the Bruce, Keith, and Rhum fields in the Northern North Sea, where Serica is the operator; and a mix of operated and non-operated fields connected to the Triton FPSO in the Central North Sea.

Serica aims to create shareholder value through a mix of production from existing oil and gas fields, organic investment and M&A.

Serica expects to complete the purchase of Prax Upstream Limited during 2025, gaining 100% ownership and operatorship of the Lancaster field situated in the West of Shetlands area. In H1 2026, Serica is also set to complete the acquisition of a 40% operated stake in the Greater Laggan Area offshore fields and associated Shetland Gas Plant from TotalEnergies and non-operated interests in the Catcher and Golden Eagle Area Development fields from ONE-Dyas.

Serica's shares trade on the AIM market of the London Stock Exchange (ticker: SQZ). More information about Serica is available on the Company's website (www.serica-energy.com). To receive news updates by email, interested parties can subscribe through the website.
