Comment on Press

London, UK – 18 April 2022 – Arqit Quantum Inc. (“Arqit”), a global leader in quantum encryption technology, notes the article in today’s Wall Street Journal which seems to be based on little more than the unsubstantiated and out of date comments of two long departed and disgruntled former employees. We were disappointed that the WSJ failed to make reference to the numerous positive announcements made by the company in recent months or other data shared with them. For example the article criticizes a technology category (“QKD”) that Arqit does not even sell, as it in fact notes in its own article. The Wall Street Journal story was comprehensively and categorically rebutted with verified evidence offered. When considering the efficacy and relevance of its products, Arqit is content to let its customers and results do the talking and looks forward to its forthcoming results announcement in May.

These factors are difficult to predict accurately and may be beyond Arqit’s control. Forward-looking statements in this communication or elsewhere speak only as of the date made. New uncertainties and risks arise from time to time, and it is impossible for Arqit to predict these events or how they may affect it. Except as required by law, Arqit does not have any duty to, and does not intend to, update or revise the forward-looking statements in this communication or elsewhere after the date this communication is issued. In light of these risks and uncertainties, investors should keep in mind that results, events or developments discussed in any forward-looking statement made in this communication may not occur. Uncertainties and risk factors that could affect Arqit’s future performance and cause results to differ from the forward-looking statements in this release include, but are not limited to: (i) risks that the business combination disrupts Arqit’s current plans and operations, (ii) the outcome of any legal proceedings that may be instituted against the Arqit related to the business combination, (iii) the ability to maintain the listing of Arqit’s securities on a national securities exchange, (iv) changes in the competitive and regulated industries in which Arqit operates, variations in operating performance across competitors, changes in laws and regulations affecting Arqit’s business and changes in the combined capital structure, (v) the ability to implement business plans, forecasts, and other expectations after the completion of the business combination, and identify and realize additional opportunities, (vi) the potential inability of Arqit to convert its pipeline or orders in backlog into revenue, (vii) the potential inability of Arqit to successfully deliver its operational technology which is still in development, (viii) the risk of interruption or failure of Arqit’s information technology and communications system, (ix) the enforceability of Arqit’s intellectual property, and (x) other risks and uncertainties set forth in the sections entitled “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in Arqit’s annual report on Form 20-F, filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 16, 2021 and in subsequent filings with the SEC.
