Coresite Acquisition

Coresite was acquired by American Tower for $10B on 15 November 2021.

The acquisition price implies a 15.4x revenue and 29.4x EBITDA multiple on $655M of revenue.

Before the acquisition Coresite had raised $570M across 1 funding round.

American Tower Corporation acquired CoreSite Realty Corporation for $10.1 billion in an all-cash transaction announced on November 15, 2021, and completed on December 28, 2021. CoreSite was a leading U.S. data center REIT operating 25 data centers, 21 cloud on-ramps, and over 32,000 interconnections across eight major U.S. markets as of Q3 2021. The company generated annualized revenue of $655 million and Adjusted EBITDA of $343 million in Q3 2021, with a track record of double-digit annual revenue growth over the prior five years. American Tower structured the acquisition as a tender offer for all outstanding CoreSite shares at $170.00 per share in cash, followed by a second-step merger for any untendered shares at the same price. The transaction was unanimously approved by both companies' boards of directors and expected to create a differentiated communications real estate platform combining American Tower's cell tower infrastructure with CoreSite's data center capabilities. The deal was positioned to benefit from the convergence of wireline and wireless networks amid accelerating global 5G deployments, with American Tower planning to leverage its financial strength to accelerate CoreSite's development pipeline and evaluate international expansion opportunities in the data center space.

Stonepeak initially invested $2.5B in August 2022 for approximately 29% ownership in American Tower's U.S. data center business (CoreSite), structured as common equity and mandatorily convertible preferred equity, implying an enterprise value of $10.5B; American Tower retained operational control with Stonepeak gaining governance rights.
