• Malaysia senior secured syndicated term financing upsized to approximately US$7.2 billion in total for Johor platform
• 1GW of IT Power Capacity now generating income under long-term customer contracts; 2.3GW of Bookings^[1,2] committed by customers and Reservations^[3] of 1.1GW
• Showcasing DayOne's ability to deliver on customer commitments at scale

SINGAPORE, Oct. 14, 2026 /PRNewswire/ -- DayOne Data Centers Limited ("DayOne"), a Singapore-headquartered global digital infrastructure platform, today announced it has surpassed 1GW of Billings^[4]. This follows the recent upsize of its senior secured multi-currency syndicated term financing in Malaysia to approximately US$7.2 billion in total. These milestones demonstrate DayOne's ability to deliver on customer commitments and execute at scale.

DayOne continues to strengthen its capital base to support its growth. Arranged by a seven-lender consortium, the upsized financing of approximately US$7.2 billion in Malaysia supports the continued development of its data center platform in Johor and builds on the approximately US$3.5 billion syndicated financing the company secured in May 2025. Since 2024, the company has raised over US$6 billion in equity across several financing rounds, alongside project financing from a broad roster of more than 30 local and global banking partners.

DayOne's Billings have grown over eightfold in under two years, from 121MW at the end of 2024. The 1GW Billings milestone comes as DayOne's Bookings reached approximately 2.3GW^[1], up from 1.25GW at the end of 2025. In addition to the Bookings, DayOne also had 1.1GW^[1] of Reservations^[3] from customers.

Jamie Khoo, Chief Executive Officer of DayOne, said, "The confidence our banking partners and customers have placed in DayOne is reflected in these milestones and underpins our continued growth. Together, their support has enabled us to unlock strategic capacity for the next generation of AI and cloud infrastructure. Our focus remains on earning that trust through responsible execution and bringing capacity online at speed and scale in the markets our customers need."

DayOne acquires powered land and secures anchor customer commitments early on in its development process. Across its ten-market footprint, DayOne's Resources^[5] reached 4.6GW^[1], up from 2GW at the end of 2025.

A key part of DayOne's growth strategy is to continue broadening and diversifying its customer base over time. Bookings came from 15 customers^[1], up from nine at the end of 2024. Four of its top five customers are with DayOne in multiple markets. Three hyperscale customers each have multi-market deployments of around or above 200MW. Most recently, DayOne has secured additional orders with one of its existing U.S. hyperscale customers.

"By pioneering and scaling new markets, this conviction has shaped DayOne since inception, and it continues to guide how we grow," added Jamie. "From Singapore where DayOne was founded, we are driving the delivery of high-specification facilities across Asia Pacific and Europe."
