Significant events
- “On 28 June 2024 the Company completed the sale of its site to Great British Nuclear (GBN), and as part of the sale the Company agreed to support GBN with estate and site management services from 28 June 2024 until 31 December 2025.”
- “Completion occurred on 28 June 2024 when all relevant third-party consents were obtained, completion conditions were achieved, and other transaction documents were delivered. Completion of the sale resulted in a non-operating gain on disposal.”
- “The Company will continue to provide transitional services to GBN until 31 December 2025.”
- “Following completion of the transitional services, the Company will be retained until 31 June 2027 when warranties on the sale expire. It is the Ultimate Shareholder's intention that following payment of the deferred consideration and expiry of the warranty period, the Company will then be liquidated.”
