Crown Castle Inc. has completed the $8.5 billion sale of its Fiber Solutions business to Zayo Group and its Small Cell business to Arium Networks, marking its pivot to a pure-play tower company model. The transaction adds 90,000 route miles of fiber to Zayo’s network to support AI and cloud infrastructure, while the small cell assets were acquired by Arium Networks, which is backed by the EQT Active Core Infrastructure fund. Crown Castle will utilize the proceeds to aggressively reduce outstanding debt by over $7.0 billion, significantly deleveraging its balance sheet. Additionally, the company has authorized a $1.0 billion share repurchase program to return capital to shareholders. This strategic divestiture allows the company to optimize its financial profile while focusing exclusively on its core tower infrastructure. The company also updated its 2026 financial outlook to reflect this new capital structure.
