Zayo’s Fiber Fuels Global Innovation. Both are experienced global investors in the
communications infrastructure space, and they appreciate our extraordinary fiber infrastructure
assets, our highly talented team and our strong customer base. I am confident this partnership
with EQT and Digital Colony will empower Zayo to accelerate its growth and strengthen its
industry leadership.”

infrastructure portfolio, including a highly-dense fiber network in some of the world’s most

growing demand for data associated with the connectivity and backhaul requirements of a range
of customers. We are excited to work alongside the management team and EQT to grow the
business and expand its presence in the global market.”

commitment to investing in market leading infrastructure companies whose innovations and
services are transforming society,” said Jan Vesely, Partner at EQT Partners, Investment
Advisor to EQT Infrastructure. “As one of the most active global infrastructure investors with a
demonstrated track record of success in the telecommunications and fiber industry, we are
confident that EQT, along with Digital Colony, are ideal partners for Zayo as the Company
embarks on its next phase of growth. We look forward to working closely with Zayo’s global
team, whose entrepreneurship, collaboration and customer partnerships are best in class.”
“Following a comprehensive review of strategic alternatives, the Zayo Board of Directors
concluded that the sale of Zayo to Digital Colony and EQT Infrastructure is in the best interest of
Zayo and all its stakeholders,” said Yancey Spruill, Zayo’s Lead Independent Director. “The
transaction delivers immediate and substantial value to shareholders and will strengthen Zayo’s
financial flexibility, enabling the company to increase investments and better position itself for
long-term growth and profitability.”
