Insights

Capital markets and restructuring analyst

Process step: UK court filings advance Part 26A plan using 3(a)(10).

Argo Blockchain is progressing a Part 26A UK restructuring, having filed a claim form and court bundles with the High Court. Part 26A enables a court-sanctioned plan across creditor classes, which can facilitate balance sheet changes when approved.

The Company states the plan will be structured to rely on Section 3(a)(10), a U.S. exemption that permits issuing securities without SEC registration when a court approves the fairness of the exchange. This signals potential issuance of securities as part of the plan.

Next milestones typically hinge on court hearings and class approvals. Actual impact will depend on the plan terms and any court-sanctioned distributions of securities. Plan Participants can request bundles via the listed emails for details.
