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 operates assets that deliver around 10% of the UK's gas production, a key component of the UK energy system, and has invested over £1 billion in the UK supply chain since 2020. Serica maintains a broadly balanced output of oil and gas across its operations.

The Company's key producing assets are currently 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. The Company also holds a notable position West of Shetland, including a 40% operated stake in the Greater Laggan Area offshore fields and associated Shetland Gas Plant.

In the second half of 2026 Serica also intends to complete the acquisition of non-operated interests in the Catcher and Golden Eagle Area Development fields from ONE-Dyas, and the acquisition of a package of operated and non-operated assets from Spirit Energy in Q3 2026, including a 15% stake in the Cygnus field and 25% in Clipper South as well as the operated Greater Markham Area.

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

Serica's shares trade on the AIM market of the London Stock Exchange (ticker: SQZ), and the Company has announced its intention to move its listing to the Main Market of the LSE in 2026.
