DayOne Data Centers, a Singapore-headquartered global digital infrastructure platform that develops, owns, and operates hyperscale and AI-ready data center campuses, has announced the final closing of its Series C equity financing, with total gross proceeds of US$ 4.5 billion.
The Series C equity financing is expected to enable DayOne to accelerate its expansion in key markets including Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong, Finland, and Spain.
“Since our inception in 2022, DayOne has secured more than 1.5 GW of total bookings for capacity across Asia Pacific and Europe, making us one of the largest and fastest-growing international digital infrastructure platforms,” said DayOne in a statement. “DayOne may continue to consider additional equity and debt financing options in the private and public markets, subject to its funding needs, market conditions and other considerations.”
The Series C round was led by existing investors Coatue Management and Hillhouse Investment, who have now become DayOne’s two largest shareholders. There was also participation from notable new investors including the Indonesia Investment Authority (INA) and Achi Capital Partners.
