Update on 2020 results

The Company is continuing to work hard to prepare the annual report and accounts (the "ARA") and liaise with its auditors to finalise the audit of the financial statements for the year ended 31 December 2020 (the "2020 Results"). The Group is now expecting to report £43m of aggregate losses identified since the position reported in the 2019 financial statements, this figure remains subject to audit. The increased losses are largely covered by contingencies included within the working capital and cash projections used to support the Company's refinancing and also includes some losses which are likely to reverse in FY21.

In addition, it is no longer expected that the 2020 ARA will be released in August, a further update will be provided in due course.

The Company is progressing well to conclude the required documentation to convene a general meeting to seek shareholder approval to complete the refinancing at the earliest opportunity.

Lee Marks Chief Executive Officer said:

"We are looking forward to fully recapitalising the business allowing us to normalise our relationships with our supply chain.

I look forward to leading the business into a new positive chapter alongside my Executive team and Svella plc."
