Zayo Group Holdings

Follow-on Offering

Co-Manager, March 2015

Zayo owns about 130,000 route miles of fiber, which underlies most of its business and is in over 400 markets throughout the U.S., Canada, and Europe. In its biggest segment, Fiber Solutions, Zayo leases dark fiber on long-term contracts primarily to communications service providers. In its Transport and Enterprise Networks segments, Zayo similarly leases fiber to customers to transport data, but it has a range of offerings over fiber that Zayo has lit, saving customers from having to activate and customize it themselves. Zayo also operates 50 U.S. data centers, provides cloud services, and owns a small Canadian telecom company, Allstream, that serves business customers. In 2018, Zayo announced its intention to split its business into two companies by the end of 2019.
