BOULDER, Colo. – March 9, 2020 – Zayo Group Holdings, Inc. (“Zayo”) (NYSE: ZAYO), which
provides mission-critical bandwidth to the world’s most impactful companies, today announced
the completion of its acquisition by affiliates of Digital Colony Partners (“Digital Colony”) and the
EQT Infrastructure IV fund (“EQT” or “EQT Infrastructure”). The close marks the consummation
of the $14.3 billion transaction, which represents the largest syndicated private equity
investment, the fifth largest Media & Communications LBO and the second largest LBO overall
since 2008.

Under the terms of the merger agreement, which was approved by Zayo’s stockholders at a
special meeting held on July 26, 2019, Zayo stockholders will receive $35 in cash per share of
Zayo common stock. As a result of the transaction completion, Zayo is now a privately held
company and its common stock has ceased trading on the NYSE.

Founded in 2007, Zayo has grown through both organic investment and 45 acquisitions to
become the leading independent provider of communications infrastructure. With deep, dense
metro and long haul networks across the U.S., Canada and Western Europe, Zayo serves many
of the largest and most innovative companies in the world. Before going public in 2014, Zayo’s
original private equity investors funded the company with just over $1 billion of equity; with
today’s transaction close, that equity is worth over $8 billion, creating material value for
shareholders. Beyond shareholder value, Zayo has also established itself over the past 13
years as a top employer along Colorado’s front range and as an active participant in the
communities in which it operates.

“We are excited to launch this new chapter of Zayo, as a private company under the ownership
of a consortium led by two highly experienced infrastructure investors who have a deep
understanding of our business and bring significant value to Zayo,” said Dan Caruso, Zayo’s
chief executive officer. “This is a great outcome for the company, its former shareholders, our
customers and employees, and our new ownership group. As a private company, we will have
greater flexibility to pursue our long-term strategy and leverage our fiber to fuel global innovation
for our customers.”

“EQT has a strong track record of supporting market leading companies and we look forward to
working with the entire Zayo organization as it embarks on its next phase of growth as a private
company,” said Jan Vesely, Partner at EQT Partners, Investment Advisor to EQT Infrastructure.
“Zayo is ideally positioned to meaningfully expand its offerings and services against the
backdrop of accelerating demand for innovative fiber infrastructure solutions.”

“Zayo has amassed a world class network that is unparalleled in the markets they serve,
supporting the world’s most innovative companies,” said Marc Ganzi, CEO of Digital Colony and
CEO-Elect of Colony Capital. “We believe that fiber networks are the crucial connective element
in the digital infrastructure ecosystem, and we look forward to partnering with the Zayo team to
execute on the plan of leveraging these powerful assets and driving growth with our customers
across multiple markets and verticals.”

Goldman Sachs and J.P. Morgan served as financial advisors to Zayo Group in connection with
the transaction and Skadden Arps served as legal counsel. Morgan Stanley and Deutsche Bank
acted as financial advisors to Digital Colony and EQT Infrastructure and Simpson Thacher
served as legal advisor.
