en.Wedoany.com Reported - U.S. digital infrastructure provider Zayo Group Holdings officially announced on May 1, 2026, the completion of its acquisition of Crown Castle's Fiber Solutions business for $4.25 billion. This transaction marks the 50th and largest acquisition in Zayo's history, further solidifying its dominant position in the North American fiber infrastructure sector.

Zayo CEO Steve M. Smith directly addressed the strategic rationale behind the acquisition in an official statement. He noted that as artificial intelligence becomes increasingly embedded in the global economy, the resulting demand for connectivity is unprecedented, making high-capacity fiber infrastructure indispensable. Zayo's decades-long focus on building and operating large-scale fiber networks forms the foundation for capturing and unlocking the full value of these assets. Smith emphasized that the combination of long-haul backbone and deep metro fiber will create a differentiated platform, positioning Zayo as the partner of choice for high-capacity connectivity.

The acquired Crown Castle Fiber Solutions business adds approximately 90,000 route miles and around 40,000 on-net enterprise access points to Zayo, heavily concentrated in metropolitan areas across the U.S. Northeast, Southeast, Midwest, and West Coast. Following the transaction, Zayo's total North American network route miles reach 224,000. For existing customers, on-net access, route diversity, and capacity in core markets have been materially enhanced; for new enterprise customers, the scale advantages of Zayo's national backbone network will provide stronger access capabilities to data centers, cloud platforms, and the AI ecosystem.

This acquisition is based on Zayo's assessment of the evolution path of AI workloads. Zayo CFO Jeff Noto pointed out that the company sees long-term positive factors driving fiber infrastructure demand, which continue to guide the company's capital allocation direction. Zayo Chief Product and Strategy Officer Bill Long disclosed for the first time after the transaction's completion that the company has signed a new long-haul fiber anchor customer agreement, under which it will build six new long-haul fiber routes totaling 3,000 miles and expand capacity on nine existing high-capacity corridors, adding over 5,000 miles of new fiber. Long called the agreement "the largest newly built long-haul fiber project announced in the industry over the past 25 years."

Crown Castle simultaneously confirmed the transaction's completion. Crown Castle President and CEO Chris Hillabrant stated that following the transaction, Crown Castle becomes the only pure-play tower company focused on the U.S. market. Crown Castle will use a portion of the sale proceeds to repurchase $1 billion in shares and reduce outstanding debt by over $7 billion. The sale also involved Crown Castle's small cell business, which was independently acquired by the EQT Active Core Infrastructure fund and renamed Arium Networks, bringing the total overall transaction consideration to approximately $8.5 billion. Zayo and Arium Networks concurrently signed a long-term fiber supply commercial agreement.

Zayo is headquartered in Denver, Colorado, supported by digital infrastructure investment firm DigitalBridge Group, and operates the largest independent fiber network in North America. As of the completion of this acquisition, Zayo's cumulative investment in this network has exceeded $35 billion. The company has been recognized as "Network Innovator of the Year," and its core wavelength network has achieved 100% 400G speed support capability.
