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.
