Exhibit 99.1

GDS AnnouncesSale Of US$385 million DayOne Shares

SHANGHAI, China, January 13, 2026 (GLOBE NEWSWIRE) -- GDS Holdings Limited (“GDS Holdings”, “GDS” or the “Company”) (NASDAQ: GDS; HKEX: 9698), a leading developer and operator of high-performance data centers in China, today announced that it has entered into definitive agreements with DayOne Data Centers Limited (“DayOne”), a Singapore-headquartered hyperscale data center platform in which the Company holds a minority equity investment, pursuant to which DayOne will repurchase ordinary shares of DayOne from GDS to the value of US$385 million. The share repurchase price per ordinary share is the same as the price for DayOne’s recently announced Series C convertible preferred share new issue of over US$2.0 billion.

The share repurchase will enable GDS to recycle approximately 95% of its principal invested in DayOne at a nearly 6.5 times multiple of money. The value of GDS’s remaining equity interest in DayOne implied by the Series C new issue price is over US$2.2 billion, equivalent to US$11.18 per GDS American Depositary Share. GDS currently intends to reallocate the proceeds of the share repurchase to invest in compelling new business opportunities with attractive return potential in its core business in China.
