What Is Arqit Quantum's Investment Narrative?

To own Arqit Quantum today, you have to believe that its quantum‑safe encryption can translate recent technical wins into a real, scalable business before cash constraints bite. The latest full-year results help a little on that front: losses narrowed to US$35.34 million and revenue edged up to US$530,000, while the new fiscal 2026 target of about US$1.20 million finally gives a concrete, if modest, near-term milestone to track. That guidance modestly strengthens the short-term catalyst around commercial traction with telcos, defense and confidential computing partners, especially after the recent Sparkle deployment and tier‑1 telco contract. At the same time, the tiny revenue base, volatile share price and less than one year of cash runway keep funding risk front and center, so the investment story still hinges on execution rather than numbers.

However, one key funding risk could quickly change the picture for existing shareholders. According our valuation report, there's an indication that Arqit Quantum's share price might be on the expensive side.
