Arqit Quantum Inc. is launching an at-the-market offering of up to $125,000,000 of its ordinary shares under a sales agreement with Cantor Fitzgerald & Co. and H.C. Wainwright & Co., LLC. The shares may be sold from time to time on Nasdaq or through other permitted methods at prevailing market, related or negotiated prices, and the agents will receive up to 3.0% of the gross sales price as compensation.
Arqit plans to use net proceeds for general corporate purposes, including continued product development and commercialization, potential acquisitions and other business opportunities, and repayment of indebtedness. As of September 30, 2025, it had 15,291,767 ordinary shares outstanding, so additional issuances under this program would dilute existing holders.
The company highlights risks that the actual number of shares sold and gross proceeds may be lower than $125.0 million, that investors buying at different times may pay different prices and experience varying dilution, and that future equity or equity-linked financings could further pressure the share price. As a foreign private issuer and emerging growth company, Arqit also benefits from reduced U.S. reporting requirements.
Arqit Quantum Inc. filed Amendment No. 1 to its Form F-3 registration statement to modify the amount of unsold securities previously registered pursuant to Rule 415(a)(6) and to update the exhibit index. The amendment consists only of the facing page, an explanatory note, Part II, the signature page and Exhibit 107. The filing indicates the registrant is an emerging growth company and that securities may be offered on a delayed or continuous basis.
Arqit Quantum Inc. has agreed to settle a previously disclosed putative securities class action in the U.S. District Court for the Eastern District of New York for $7 million, under a settlement agreement executed on January 9, 2026 and submitted to the court for documentation and approval. The case, referred to as the Federal Action, involved the company and certain of its directors. Assuming the court approves the settlement, the company will seek dismissal of a related putative class action in the Supreme Court of the State of New York, which has been stayed because it falls entirely within the settlement classes of the Federal Action. The information in this report is also incorporated by reference into several of Arqit’s effective Form S-8 and Form F-3 registration statements.
