How to file this claim
- Confirm you are in one of three eligible classes: Centricus Class A ordinary shareholders or unit holders as of July 26, 2021; persons who purchased or acquired Arqit ordinary shares or warrants on a U.S. stock exchange during the class period; or persons who purchased Arqit securities traceable to the September 2021 offering.
- Gather documentation of your holdings, purchases, and sales of Arqit and Centricus securities, such as broker confirmation slips, monthly or yearly brokerage statements, or other records showing transaction details.
- File your claim online at the official portal or download, print, and complete the PDF claim form and mail it to the settlement administrator before the claim deadline.
- If submitting on behalf of another person or entity (as agent, executor, guardian, trustee, etc.), include proof of your authority to act.
- Each separate legal entity or separately managed account must submit its own claim form; all joint beneficial owners must sign the form.
Documents you'll need
Watch out for
- Each separate legal entity or separately managed account must submit a separate claim — one joint form does not cover multiple accounts.
- All joint beneficial owners must sign the claim form or the claim may be rejected.
- Agents, executors, administrators, guardians, conservators, and trustees must provide proof of authority when submitting on behalf of others.
- Class members whose calculated payment would be less than the minimum threshold will not receive a payout.
- For Section 10(b) claims involving securities purchased and sold before April 18, 2022, the recognized loss is zero, meaning no recovery for those transactions.
- The settlement administrator uses the first-in, first-out method to match sales against holdings and purchases, which may affect your recognized loss calculation.
We prepare — you file on the official site yourself. This is not legal advice and is not an eligibility decision; the administrator and court decide.
