John Hatem

Hatem joined CyrusOne in 2011 and has held a series of increasingly senior roles across the business. He most recently served as President, responsible for global sales, global procurement, and design, engineering, and construction in the United States. His deep experience in data center design, development, and operations has helped transform CyrusOne into one of the world’s leading digital infrastructure providers for hyperscale and enterprise customers.

Hatem has a proven track record of leadership, strategic vision, operational expertise, and a deep understanding of the market dynamics shaping the future of digital infrastructure. He has been equally committed to ensuring CyrusOne is a trusted presence in every community where it operates, recognizing that sustainable growth requires being a good neighbor.

“In his nearly 15 years with CyrusOne, John has become the heart and soul of the company, having established a strong track record of building outstanding teams, carrying out winning strategies, and leading operations that must continue to move at the speed of technological innovation,” said Waldemar Szlezak, Partner at KKR, and Will Brilliant, Partner at Global Infrastructure Partners. “He has earned the trust of many of the world’s leading enterprises, the local communities in which CyrusOne operates, and his teammates. The opportunity for CyrusOne has never been greater and we are confident that John is the right person to guide the company forward. No one understands the company’s customers, capabilities, and potential more deeply than he does.”

“The team at CyrusOne has built something special: a company with the engineering discipline, operational expertise, and talented personnel to deliver world-class data center capacity at the speed and scale that our customers expect,” said Mr. Hatem. “I have never been more excited about what lies ahead. As workloads become more power-intensive and demand for faster delivery grows, our structural advantages have never mattered more.”

Mr. Szlezak and Mr. Brilliant added, “Four years ago, Eric came to CyrusOne to grow the business at a critical time for the company and the industry. He and the team have delivered a period of record revenue growth and profitability marked by the largest customer expansion in our history, and we are grateful for his leadership. Today, CyrusOne is a stronger, larger, and better company that is poised to capitalize on the extraordinary demand for AI infrastructure.”

“It has been a privilege to lead CyrusOne and I could not be more confident in John’s leadership to take the Company into its next phase of growth,” said Mr. Schwartz.
