Rhea-AI Filing Summary

Restructuring & Capital Markets Analyst

Court-sanctioned plan is pivotal; failure risks insolvency and LSE delisting proceeds if approved.

The company outlines a Part 26A restructuring path with a clear court timetable: convening on Nov 5, 2025, creditor/shareholder meetings on Nov 28, 2025, and sanction on Dec 8, 2025. The filing states reliance on Section 3(a)(10) for exemption, indicating a court-approved compromise process.

Argo intends to delist from the LSE while retaining its NASDAQ listing, conditional on sanction. The delisting would take effect at 8:00 a.m. Dec 9, 2025, with the last LSE trading day on Dec 8, 2025. This concentrates liquidity on NASDAQ and removes the UK venue.

The company warns that absent sanction on or shortly after Dec 8, 2025, it would likely be unable to pay debts and may enter a formal insolvency process. Actual impact turns on the court’s decision and stakeholder voting outcomes disclosed in the Practice Statement Letter.

• To date, the Company drawn approximately US$5.38 million from its secured multi-draw term loan facility of up to US$7.5 million with Growler.
