Accordingly, the financial statements have been prepared on a basis other than going concern as described in Note 1.”

- “On 28 June 2024 the Group completed the sale of its sites at Oldbury and Wylfa to Great British Nuclear (GBN), and as part of the sale the Group agreed to support GBN with estate and site management services from 28 June 2024 until 31 December 2025.”
- “the defined benefit pension scheme buy-out completed in September 2024 when the scheme was closed and surplus cash was returned to the Group.”
- “Following completion of the transitional services, the Group will be retained until 31 June 2027 when the deferred element of the payment for the Oldbury site is due from GBN (subject to the outcome of site conditions) and when warranties on the sale expire. It is the Shareholder's intention that following payment of the deferred consideration and expiry of the warranty period, the Group will then be liquidated.”
