GDS Holdings Limited is a leading data center operator in mainland China that provides colocation services—secure, reliable hosting infrastructure for customer IT equipment—as its primary revenue source, supplemented by managed services, IT equipment sales, and consulting. The company serves a diversified customer base concentrated in high-value sectors, particularly cloud service providers and internet companies, operating self-developed and third-party data centers across established markets in eastern China with strategic expansion into western regions. The business follows a capital-intensive model requiring substantial upfront investment in infrastructure before revenue generation, with growth driven through capacity expansion, new facility construction, selective acquisitions, and asset monetization programs to recycle capital.
