EXPLANATORY NOTE
On January 9, 2026, Arqit Quantum Inc. (the “Company”) and counsel for the plaintiffs in the previously disclosed putative class action lawsuit filed against the Company and certain of the Company’s directors in the United States District Court for the Eastern District of New York (the “Court”) (Case No. 1:22-cv-02604) (the “Federal Action”) executed a settlement agreement that will resolve the Federal Action for $7 million, which has been submitted to the Court for further documentation and approval.
Assuming Court approval of the settlement, the Company will seek dismissal of the previously disclosed putative class action lawsuit that was filed against the Company and certain of its directors in the Supreme Court of the State of New York (the “State Court”) (Index No. 153555/2023) (the “State Court Action”), which has been stayed per order of the State Court pending final adjudication of the Federal Action because the State Court Action falls entirely within the settlement classes of the Federal Action.
Other than as indicated below, the information in this Report of Foreign Private Issuer on Form 6-K (including the exhibits hereto) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act. The information furnished in this Report of Foreign Private Issuer on Form 6-K is hereby incorporated by reference into the Company’s registration statements on Form S-8 (File Nos. 333-262215, 333-275960 and 333-284706) and Form F-3 (File Nos. 333-268786, 333-259982, 333-284343 and 333-289939), and shall be a part thereof, to the extent not superseded by documents or reports subsequently filed or furnished.
