CyrusOne Sells GDS Shares to Raise Approximately $200 Million of Proceeds

Sponsored by Businesswire

CyrusOne Inc. (NASDAQ: CONE), a premier global data center REIT, today
announced that it has sold approximately 5.7 million American depository
shares (“ADSs”) of GDS Holdings Limited (“GDS”) (NASDAQ: GDS) for a
total purchase price of approximately $200 million. CyrusOne will
continue to hold approximately 2.3 million ADSs, valued at approximately
$90 million based on the GDS closing price on April 11, with the
remaining shares being subject to a six-month lock up. The commercial
agreement between CyrusOne and GDS will remain in place, and Gary
Wojtaszek, CyrusOne’s President and Chief Executive Officer, remains a
member of the GDS Board of Directors.

“GDS has created substantial value for its shareholders over the last 18
months, in turn allowing us to recycle capital and generate significant
cash proceeds from the sale of shares, while maintaining a position that
approximates our original investment,” said Wojtaszek. “This transaction
replaces a meaningful portion of our equity capital requirements for the
year, with the proceeds being deployed to fund attractive, profitable
growth opportunities. William and his team have been fantastic partners,
and the nearly 20 megawatts of leases we signed last year with Chinese
hyperscale companies was a direct result of our relationship with GDS.
As two of the fastest-growing data center companies, we look forward to
continuing to work together to capitalize on the strong underlying
secular demand trends and meet the needs of our customers in the two
biggest economies in the world.”

This transaction was not contemplated in CyrusOne’s original 2019
guidance provided February 20, 2019. CyrusOne will provide updated 2019
guidance when the Company reports its first quarter 2019 results after
the market closes on Wednesday, May 1, 2019.

The transaction is expected to settle on April 16, 2019.
