Transaction overview

Zayo Group Holdings Inc., a U.S.-based provider of bandwidth infrastructure, acquired Crown Castle's Fiber Solutions business on May 1, 2026 for $4.2 billion, concluding an agreement that was initially announced in March 2025. The deal is part of Crown Castle’s strategy to divest non-core assets and focus on its tower operations, which it expects will generate annual adjusted EBITDA of approximately $89 million from the Fiber Solutions segment post-closure.

Deal structure and financing

The transaction involved an all-cash purchase with no disclosed equity or debt split details. Zayo did not disclose specific terms regarding leverage metrics or whether Crown Castle retained any stake in the acquired business. The deal’s financing was arranged by financial advisors including PJT Partners, J.P. Morgan, UBS Investment Bank, EQT, and Digital Bridge; however, specifics on funding sources were not provided. Given the significant size of the transaction, it is likely that Zayo secured a mix of equity and high-yield debt to finance the acquisition, though exact figures are unknown.

Strategic context

Zayo's acquisition of Crown Castle's Fiber Solutions business was driven by its strategic intent to expand its fiber network footprint across the United States. By acquiring this portfolio, Zayo aims to enhance its market presence in key regions where data infrastructure demand is growing rapidly. Conversely, Crown Castle’s decision to divest Fiber Solutions aligns with its strategy to streamline operations and focus on tower assets, which it believes will drive shareholder value through improved operational efficiency and clearer strategic direction.

Regulatory path

The acquisition has not faced any notable regulatory hurdles given the competitive landscape in U.S. telecommunications infrastructure. As both companies operate primarily within the United States, the deal was reviewed by relevant authorities such as the Federal Communications Commission (FCC) and possibly state public utility commissions. No antitrust remedies were required for this transaction, likely due to a lack of significant overlap between Zayo’s existing fiber network and Crown Castle's Fiber Solutions business in terms of geography or customer base. The parties filed HSR notifications with U.S. regulators as mandated by the Hart-Scott-Rodino Act shortly after the deal was announced.
