Insights

Equity restructuring analyst

Court decision on Argo’s restructuring plan could trigger LSE delisting.

The announcement centers on a High Court sanction hearing for Argo Blockchain’s restructuring plan under Part 26A of the Companies Act 2006. The court heard arguments on 8 December 2025 and scheduled its decision for 2:30 p.m. on 10 December 2025, which will determine whether the plan is sanctioned.

Argo states that if the Court sanctions the plan on that date, its shares will have a final trading day on the London Stock Exchange Main Market on 10 December 2025, with delisting effective from 7 a.m. on 11 December 2025. This links the restructuring outcome directly to the company’s London listing status, while the company remains dual-listed and explicitly mentions the ability to retain its Nasdaq listing as a key risk factor.

The forward-looking statements section underscores uncertainty around implementing the restructuring plan, broader market conditions, and operational, financial, regulatory, tax and legal risks. It also directs attention to risk factors in Argo’s Annual Report and Form 20-F for the year ended 31 December 2024, suggesting that the restructuring and any listing changes need to be interpreted alongside those disclosed risks.
