On October 14, 2026, Seeking Alpha downgraded Arqit Quantum Inc. to a Sell rating after the company released disappointing preliminary fiscal 2026 results. Revenue fell short of previous guidance.
Second-half revenue was affected by the end of revenue recognition from a major Middle East contract, following regional geopolitical events.
The preliminary results and downgrade have raised concerns about Arqit Quantum’s growth trajectory, valuation, and competitive position.
