Update on 2020 Results and Financing

Result of General Meeting

Financing Update

In conjunction with Svella plc and its advisors the Company continues to make good progress toward publishing a prospectus and circular to convene a general meeting to seek shareholder approval to complete the refinancing at the earliest opportunity.

Lee Marks, Chief Executive commented:

"Since the announcement on 21 June of the recapitalisation, Svella has worked very well alongside the Company to progress the transaction and remain committed to ensuring that the recapitalisation is completed at the earliest opportunity."

Financial Statements

The Company is continuing to work with its auditors to finalise the accounts for the year ended 31 December 2020 (the "2020 Results"). Subject to completion of the audit, the Group is now expecting to report overall underlying losses before tax significantly in excess of the £24m indicated in the announcement of 28 May 2021. This will include both a material element which is attributable to 2019, and recognition within the 2020 Results (rather than in 2021's financial results) of certain losses connected to the performance issues in the Group's Building business unit announced on 14 June 2021. The Group had already reflected the majority of the increased 2020 Results loss within its existing internal working capital projections.

It is currently expected that the 2020 Results will be published during August 2021 at which point the Company will submit a request to the FCA and the London Stock Exchange to lift the suspension in the listing of the Company's ordinary shares.
