According to filings on legal database Caseboard, Tristar Foods filed a notice of intention to appoint administrators on 10 September, with Farleys Solicitors overseeing proceedings.
Tristar is yet to file any accounts to Companies House since it was incorporated in late 2022.
Byron, which is is backed by Three Hills Capital and Calveton, has already been through multiple restructures, and if Tristar enters administration it would be the burger brand’s fourth insolvency situation.
In 2018, the business closed almost a third of its estate as part of a Company Voluntary Arrangement that saw Three Hills Capital Partners replace Hutton Collins as majority shareholder.
In 2020, the group was acquired by Famously Proper, a subsidiary of investment company Calveton UK Limited, in a pre-pack administration deal in which it slashed its estate by a further 30 sites, leaving it with 21 restaurants.
The group was acquired in a pre-pack deal by Tristar Foods in January 2023, closing nine restaurants and leaving it with 12. Later that year it closed a further three restaurants, and since then it has closed two more.
Founded by Tom Byng in 2007, at its peak it operated close to 70 restaurants and was generating annual sales of £90m. Today it trades out of just seven restaurants.
