The full resolution of securities litigation removes a significant overhang and potential future legal costs. Management can now focus entirely on operations and business development. Monitor for any Q2 2026 cash impact from the settlement payment and watch for potential new business announcements given the cleared litigation overhang.

Executive Summary
Arqit Quantum resolved all outstanding U.S. securities class actions: a federal court approved a $7 million settlement for the Eastern District of New York case, and the parallel New York state case was voluntarily dismissed. The removal of this litigation overhang removes a key uncertainty for the company.
Key Facts
- Federal court approved $7 million settlement of putative class action in Eastern District of New York (Case No. 1:22-cv-02604) on June 1, 2026
- Separate New York state putative class action (Index No. 153555/2023) voluntarily dismissed after federal settlement approval
- All federal and state U.S. securities class actions against the company have now been resolved
- Settlement amount of $7 million represents approximately 1.5% of the company's $480M market cap
- Filing signed by CEO Andrew Leaver on June 17, 2026
Financial Impact
$7 million settlement cost, approximately 1.5% of market cap
Risk Factors
- Settlement payment of $7 million reduces cash reserves for a pre-revenue company
- Underlying business fundamentals remain unproven — litigation resolution does not change revenue trajectory or product adoption
- Potential for related insurance recoveries or indemnification obligations is not disclosed
- The settlement was approved June 1 but only disclosed June 17 — two-week delay may raise governance concerns
