Why Was The Lawsuit Filed?

Among other things, the suit alleged that Arqit claimed to be a cybersecurity company with unique quantum encryption technology capable of staving off future cyberattacks, including those from quantum computers. However, it did not disclose factors such as the need for widespread adoption of new telecommunications protocols and infrastructure.

Arqit also claimed to have already signed major, long-term contracts for its services with large companies and government institutions before going public. But a Wall Street Journal investigation found that the company's revenue consisted of only a handful of government grants and small research contracts when it listed on the Nasdaq.

The Settlement

The company disclosed in an SEC filing on Wednesday that a federal court has approved the settlement agreement between the company, its directors, and the plaintiff who filed the case.

As part of the settlement, Arqit will pay $7 million, thereby resolving all class actions filed against it in the U.S.
