The transaction will position American Tower and Stonepeak to mutually benefit from the demand for low-latency, hybrid IT solutions and agile interconnection across the platform’s data center campuses, which are strategically located in key U.S. metro areas. The platform’s data center portfolio consists of 27 data centers in 10 U.S. markets, more than 450 networks, 23 native cloud on-ramps and over 35,000 interconnections.

Tom Bartlett, American Tower’s President and Chief Executive Officer, stated, “We are pleased to partner with Stonepeak in our U.S. data center business, where we expect to create value through growth in our highly interconnected, cloud on-ramp rich portfolio of data center assets. In Stonepeak, we’ve found a like-minded partner, with deep communications infrastructure experience and a long-term investment philosophy that aligns with the principles of American Tower and our longer-term strategy in the data centers segment. While this transaction supports the equity financing component for our previously completed CoreSite acquisition, it also creates a platform through which growth opportunities can be strategically evaluated and financed, with American Tower and Stonepeak committed to executing on opportunities as the 5G ecosystem continues to develop.”

Andrew Thomas, Managing Director and Co-Head of Communications at Stonepeak, added, “American Tower has established one of the premier network dense, interconnection-focused data center platforms in the U.S. through CoreSite and previous acquisitions, which we view as a great fit for our core infrastructure strategy. The platform is strategically positioned to be at the forefront of the continued shift from a traditional centralized infrastructure model to a cloud-based, connected and distributed digital infrastructure model and we are excited to partner with the American Tower team to help accelerate investment behind this trend in the years to come.”
