**EXPLANATORY NOTE**

On March 2, 2026, Nicola Barbiero resigned from the Board of Directors (the "**Board**") of Arqit Quantum Inc. (the "**Company**") and all committees thereof. Mr. Barbiero intends to pursue other commitments and his resignation from the Board is not the result of any disagreement with the Company or the Board.

Nick Pointon has advised the Company that he intends to resign from the position of Chief Financial Officer in May. The Company has identified a successor, Rob Russell, who has begun working with the Company on a part-time basis for a transition period until he assumes the position of Chief Financial Officer in May. Rob began his career in the finance department at UBS Investment Bank, where he qualified as a Chartered Management Accountant. Throughout his career, he has held a variety of senior finance roles across private equity and venture capital–backed scale-up environments. Most recently, Rob served as CFOO of Virtualstock, a Notion Capital–backed UK enterprise SaaS provider offering dropship and marketplace range-extension solutions to major retailers in the UK and internationally. In September 2025, he played a pivotal role in securing Virtualstock's successful exit to Logicbroker, a U.S. private-equity-backed competitor.

The Company thanks Mr. Barbiero and Mr. Pointon for their service.
