IREN Appoints Chief Information Security Officer

NEW YORK, July 15, 2026 (GLOBE NEWSWIRE) — IREN Limited (NASDAQ: IREN) (“IREN”) today announced the appointment of Eric Hammersley as Chief Information Security Officer.

The appointment follows the recent additions of Kambiz Aghili as Chief Product Officer and Michael Nudelman as Chief Development Officer, as IREN continues to strengthen its senior leadership team and expand its AI Cloud platform across new markets and services.

He is a U.S. Navy veteran.

Daniel Roberts, Co-Founder and Co-CEO of IREN, said:

“Security is core to how we design, build and operate our platform. As we deliver AI Cloud services to some of the most demanding customers in the world, Eric’s experience securing cloud platforms at scale will be invaluable.”
