IREN Limited (NASDAQ: IREN) appointed Anthony Lewis as chief financial officer, the data center operator announced. Lewis joined IREN in July as chief capital officer, overseeing the company's capital markets strategy and financing activities.



In his expanded role as CFO, Lewis will maintain his current responsibilities while taking on leadership of financial operations, reporting, and strategic planning. He previously spent 22 years at Macquarie Group, where he served as co-treasurer responsible for global funding, liquidity and capital management, and group financial planning and regulatory reporting.



Lewis replaces Belinda Nucifora, who served as CFO for 3.5 years and is departing the company. During her tenure, Nucifora oversaw the transition to U.S. GAAP reporting and strengthened the company's financial systems and controls, according to the announcement.



"Anthony has been a great addition to the leadership team," said Daniel Roberts, co-founder and co-CEO of IREN. "He has already contributed to the accelerated expansion of our AI Cloud business, having overseen our recently announced GPU financings."



IREN operates data centers for Bitcoin mining and AI applications using renewable energy sources. The company reports having 2,910MW of grid-connected power secured across more than 2,000 acres in the U.S. and Canada, with 810MW of operating data centers currently in use.
