DayOne’s total data-centre billings have crossed 1 gigawatt as the Singapore-based developer expands hyperscale capacity in Johor, Malaysia, backed by a total financing package of $7.2 billion from a consortium of banks.
The company said on Wednesday that its billings, defined as income-generating customer contracts for IT power capacity, had exceeded 1 GW. The figure represents an eightfold increase from 121 megawatts at the end of 2024, highlighting the rapid growth in demand for large-scale computing infrastructure in the region.
DayOne’s bookings also rose to 2.3 GW as of September 20, up from 1.25 GW at the end of 2025. Billings represent contracted capacity generating income for the company, while bookings indicate additional customer commitments for future capacity.
The announcement followed DayOne’s securing of an additional 15 billion ringgit, or $3.68 billion, in financing on Tuesday. The funding came from a consortium of seven banks and increased the company’s total financing for its Malaysia expansion to $7.2 billion.
The capital will be used to fund the expansion of hyperscale data-centre capacity in Johor, which has emerged as Malaysia’s key data-centre destination. Hyperscale facilities are large campuses designed to support the computing and storage requirements of major technology companies and other high-volume users.
The scale of the financing indicates the capital intensity of data-centre development, where projects require substantial investment in land, buildings, electrical systems, cooling equipment and network connectivity. Their operations also depend on reliable power and supporting utility infrastructure, making expansion closely linked to the capacity of local grids and industrial systems.
DayOne is headquartered in Singapore and develops and operates data centres across ten markets in the Asia-Pacific region and Europe. Its reported increase in billings and bookings comes as technology companies and digital service providers expand their demand for computing infrastructure.
Johor’s position as the focus of the company’s expansion places the state at the centre of this growth. The financing announced by DayOne is specifically intended to increase hyperscale capacity there, although the company did not provide project-by-project details, construction schedules or additional information on the power and water requirements of the planned facilities in the material reported by Reuters.
The company’s next steps will involve deploying the newly secured financing towards its Malaysia expansion and converting contracted and booked capacity into operating data-centre infrastructure. DayOne did not disclose a specific completion timeline for the expansion in the reported announcement.
