Company Further Expands its Denver Market Presence

Enhances its Interconnection Offering by Simplifying Access to the Google Cloud Platform Onramp and to More Networks for CoreSite’s Leading Any2Denver Peering Exchange in the Facility

DENVER, April 08, 2025--(BUSINESS WIRE)--CoreSite, an American Tower company (NYSE: AMT) empowering critical business and AI workloads that impact everyday life through interconnected data center solutions, today announced the acquisition of the Denver Gas and Electric Building and its related operating businesses. Located at 910 15^th Street in the heart of downtown Denver, the historic carrier hotel serves as the primary point of interconnection in the Rocky Mountain region and currently hosts CoreSite’s DE1 data center operations. With the acquisition of the #1 network-dense carrier hotel serving Denver and the Rocky Mountain region, the company plans to add approximately 3 critical megawatts (CMW) of data center capacity. This additional capacity nearly doubles DE1’s space and power footprint and furthers CoreSite’s ability to meet the growing demands of public and private cloud providers, enterprises, network and service providers.

As a result of the transaction, CoreSite will make it easier for customers to access the existing Google Cloud Platform dedicated interconnects onramp and more networks for one of the leading peering exchanges in the Rocky Mountain region, CoreSite’s Any2Denver Exchange. CoreSite will also gain about 100 of the interconnection-rich building’s customers and continue to serve as the ideal hub for performance-sensitive applications.

"CoreSite is excited to further invest and expand in our hometown market of Denver. We are planning additional investment in the historic Denver Gas and Electric Building to increase operational efficiency and offer our customers a reliable, highly interconnected environment that meets all their high-performance, high-density computing requirements," said Yvonne Ng, General Manager and Vice President of the Central Region at CoreSite. "The acquisition of this network-rich asset reinforces CoreSite as the leading interconnection provider in Denver and the Rocky Mountain region."

CoreSite’s Denver data center campus is comprised of DE1, located at the Denver Gas and Electric Building, and DE2, located at 639 E. 18^th Ave. in downtown Denver. The company is expanding the Denver campus with the construction of its DE3 enterprise-grade, purpose-built data center at 4900 N. Race Street. Once completed, DE3 will offer 97,000 square feet and 18 CMW.
