CoreSite Achieves Key Construction Milestone for New DE3 Data Center in Denver

Company Expands Existing Denver Market Footprint and Significantly Invests in Support of Local Community Organizations

DENVER--(BUSINESS WIRE)-- CoreSite, an American Tower company (NYSE: AMT) empowering critical business and AI workloads that impact everyday life through interconnected data center solutions, recently celebrated a major construction milestone for its new DE3 data center at 4900 Race Street in Denver. CoreSite’s leadership team, state and city leaders, customers, community partners and vendors gathered to commemorate the topping off of CoreSite’s newest development project.

CoreSite's new DE3 data center, located at 4900 Race Street in Denver, will be a 180,000-square-foot facility and is targeted for availability in 2026.

CoreSite’s DE3 data center will be a 180,000-square-foot facility built specifically to expand the digital infrastructure serving the Denver metro area and meet demand for high-density, high-performance compute environments that power artificial intelligence (AI), cloud and other mission-critical workloads. The company’s current Denver footprint includes two facilities located in the heart of downtown Denver. DE1, the recently purchased Denver Gas and Electric Building, which is one of the most interconnected buildings in the Rocky Mountain Region, is located at 910 15^th Street, and DE2 is located at 639 E. 18^th Ave.

DE3 is the first purpose-built colocation data center constructed in Denver in the last two decades and will be linked with high-count dark fiber to CoreSite’s existing DE1 and DE2 data centers. CoreSite’s data centers are multi-tenant colocation facilities that provide individualized space, power, cooling and connectivity services to many companies within the same building.

CoreSite calls Denver home, with headquarters in Downtown Denver, and is committed to supporting the Denver community and Globeville, Elyria and Swansea (GES) neighborhoods through this new data center location. At the event, CoreSite announced investment in the Jack A. Vickers Boys and Girls Club where the company, together with parent company American Tower, cofounded Denver’s first Digital Community.

Digital communities are connected spaces created by American Tower that offer community members access to education, career skilling, financial literacy and healthcare services. The investment includes refreshing the Club’s STEM room with new computers and accessories, iPads, a 3D digital printer and more. CoreSite, along with Schneider Electric, DPR Construction, Power Distribution Systems and Power Systems West, pledged an additional $25,000 contribution to local community organizations serving the GES neighborhoods.

“At CoreSite, we are committed to supporting the cities and communities where we operate. Our nearly 190 Denver-based employees are beyond excited to further invest in their hometown,” said Adam Post, SVP of Corporate Development and Finance at CoreSite. “On a citywide scale, DE3 will provide customers with the interconnection and improved computing performance needed to thrive, strengthening Denver’s reputation as a tech hub and driving economic growth.”

Once completed, CoreSite’s Denver data center campus expansion will deliver approximately 600,000 square feet with 60 critical megawatts of power. It is targeted for availability in 2026.
