MED Binding Joint Venture Agreement Completion Update

Mast Energy Developments PLC, the UK-based multi-asset owner, developer and operator in the rapidly growing flexible power market, announces that further to its previous announcements dated 12 July 2023, 4 August 2023, and 1 September 2023 respectively, it has further extended the completion long-stop date for the first definitive and binding Joint Venture Agreement ('JVA'). Completion is now expected around mid-October 2023. The further extension is required to allow the JV investor consortium to complete the compulsory statutory process, as set out in the announcement of 1 September 2023. This process and timelines associated therewith remains beyond the control of the Company and the JV investor who remains fully committed to see this completed at the earliest possible date.

Although MED is continuing to work with the investor consortium, and the board have full confidence that the transaction will be completed, unless or until the first definitive and binding Joint Venture Agreement ('JVA') has been completed, Seira Capital Ltd ('Seira') remains contractually bound under the JVA, and remains in breach of its obligations thereto. Should the investor consortium fail to complete the transaction around the latest completion extension date, MED will consider all its options, including but not limited to commencing legal proceedings against Seira and affected parties, as well as alternative investment opportunities.

Pieter Krügel, CEO of MED, commented: "We remain confident that the investor consortium will be able to complete the transaction and the board have also received written reassurance from the investor consortium in this regard."
