THIS ANNOUNCEMENT IS AN ANNOUNCEMENT FALLING UNDER RULE 2.8 OF THE UNITED KINGDOM ("UK") CITY CODE ON TAKEOVERS AND MERGERS (THE "TAKEOVER CODE").

THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION FOR THE PURPOSES OF ARTICLE 7 OF REGULATION 2014/596/EU, WHICH IS PART OF UK DOMESTIC LAW PURSUANT TO THE MARKET ABUSE (AMENDMENT) (EU EXIT) REGULATIONS (SI 2019/310) ("UK MAR").

FOR IMMEDIATE RELEASE

Proposed Combination of Kistos plc with Serica Energy plc - No Intention to Make a Firm Offer

Kistos plc ("Kistos") is disappointed that, despite repeated attempts by Kistos, the Board of Serica Energy plc ("Serica") has failed to engage meaningfully either with respect to Kistos' proposed offer for Serica or the terms of Serica's offer for Kistos despite the board of directors of both companies acknowledging the industrial logic in combining the portfolios of the two companies. As a result, Kistos today formally announces that it will not make a firm offer for Serica.

The Board of Kistos (the "Kistos Board") remains confident in Kistos' strategic direction and positioning as an independent North Sea gas champion and proactive consolidator in the sector. The Kistos Board remains focussed on delivery of Kistos' strategic goals.

The Kistos Board will therefore continue to pursue other paths to deliver further on those goals, with the objective of enhancing shareholder value and driving scale and consolidation, as it has successfully done since the Company's inception in 2020.

Important Takeover Code notes

This is a statement to which Rule 2.8 of the Takeover Code applies.

As is customary under Rule 2.8 of the Takeover Code, Kistos reserves the right to make or participate in an offer for Serica (and/or take any other actions which would otherwise be restricted under Rule 2.8 of the Takeover Code) within the next six months following the date of this announcement:

i)    with the agreement of the Serica Board;

ii)  following the announcement of a firm intention to make an offer for Serica by or on behalf of a third party;

iv)   where the Takeover Panel has determined that there has been a material change of circumstances.

Kistos confirms that this announcement is not being made with the consent of Serica.

About Kistos

Kistos plc was established to acquire and manage companies in the energy sector engaging in the energy transition trend. The Company has acquired Tulip Oil Netherlands B.V., which has a portfolio of assets, including profitable, highly cash generative natural gas production, plus appraisal and exploration opportunities. In addition, Kistos acquired a 20% interest in the Greater Laggan Area (GLA) from TotalEnergies in July 2022. The GLA includes four producing fields and a development project.

Kistos is a low carbon intensity gas producer. The Q10-A gas field in the Dutch North Sea (60% operated working interest) has recorded a Scope 1 carbon emissions intensity of 13g CO2e/boe since inception. This compares to an industry average of 22kg CO2/boe for gas extracted from the UK continental shelf. The Q10-A normally unmanned installation is located approximately 20 km from the Dutch shore. It is powered sustainably via wind and solar power and is remotely operated, limiting offshore visits, which are conducted by boat.
