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.

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." | Notes: | | [1] As of September 20, 2026. | | [2] "Bookings" refers to the total IT Power Capacity committed by customers pursuant to the terms of legally binding customer contracts. | | [3] "Reservations" refers to the total IT Power Capacity for which we have received capacity reservations from customers pursuant to the terms of legally binding customer contracts.

7-Lender consortium arranges expanded multi-currency financing for DayOne's data centre development in Johor.

7-Lender consortium arranges expanded multi-currency financing for DayOne's data centre development in Johor. * 2026 * 13 Oct 2026 * 3 mins read The digital infrastructure financing will support the next phase of hyperscale data centre growth in Malaysia Singapore, 13 October 2026 - A consortium of seven lenders comprising CIMB, Crédit Agricole CIB, DBS, Maybank, OCBC, Standard Chartered and UOB has successfully arranged an expanded multi-currency financing for DayOne to support the continued development of its data centre platform in Johor, Malaysia. The financing consists of an additional USD2.4 billion offshore term loan facility and RM5.5 billion Murabahah facility, totalling RM15 billion. Together with the RM15 billion multi-currency financing secured in 2025, the financing platform now totals RM30 billion, reinforcing DayOne's commitment to expanding hyperscale data centre capacity in Johor. As demand for cloud computing, artificial intelligence (AI) and digital services continues to accelerate, the development of scalable and resilient digital infrastructure will play a critical role in strengthening regional connectivity and supporting economic growth. The additional financing will fund the next phase of capacity development across the DayOne platform, helping to meet this growing demand and support the continued development of digital infrastructure in the region. The facility was arranged by a consortium of Mandated Lead Arrangers, Bookrunners and Joint Coordinators comprising CIMB, Crédit Agricole CIB, DBS, Maybank, OCBC, Standard Chartered and UOB, reflecting strong financing confidence in the development of digital infrastructure in Malaysia and the broader region. Mr Edmund Leong, Head of Group Corporate Banking, UOB, said, "As DayOne's primary relationship bank, UOB is supporting the infrastructure that will underpin ASEAN's next phase of growth. The rapid build-out of AI, cloud computing and digital infrastructure is creating one of the most significant investment opportunities the region has seen in decades, requiring not only capital but also strong ecosystems, connectivity and long-term partnerships. Leveraging our extensive ASEAN network, UOB is well positioned to connect capital, infrastructure and growth opportunities, helping clients seize the opportunities emerging from the region's accelerating digital transformation." The transaction also reinforces Malaysia's position as a leading regional digital infrastructure hub. Johor has attracted significant investment in data centre development, supported by its strong connectivity, robust infrastructure, access to skilled talent and proximity to regional markets. This will contribute to the development of a resilient digital economy and strengthen Southeast Asia's role as a key destination for technology investment and innovation. Since its establishment in 2022, DayOne has rapidly expanded its footprint across Asia and Europe, with a presence in Singapore, Malaysia, Indonesia, Thailand, Japan, Hong Kong SAR, Finland and Spain.

Bridge Data Centres seeks to upsize loan to $6.6B amid growth talks

Bridge Data Centres seeks to upsize loan to $6.6B amid growth talks. The Singapore-based hyperscale operator is pursuing one of the largest data center financings in Asia as demand from AI and cloud computing reshapes the region's infrastructure race. 2 hours ago Sponsored: Vera - AI-powered prediction market intelligence, built for serious analysts Explore Vera Bridge Data Centres is in talks to increase its loan facility to about $6.6 billion, a move that would cement its position as one of the most aggressively expanding data center operators in Asia. The Singapore-based company, majority-owned by Bain Capital, has been on a financing tear that makes most infrastructure deals look modest by comparison. The article states "$6.6 billion" but the research consistently states "up to $6 billion." This is a factual discrepancy I must flag, but per the task I will retain only what is supported by research. Bridge Data Centres is in talks to increase its loan facility to up to $6 billion. The Singapore-based company, majority-owned by Bain Capital, is building out what it hopes will be roughly 2 gigawatts of regional capacity by 2030. What's driving the deal. The proposed upsized loan builds on a $2.8 billion senior secured bank loan the company closed in March 2025, which was aimed at expanding operations primarily across Malaysia and Thailand. A key piece of the funding is expected to support a major campus project in Thailand. The QHI01 campus is planned for up to 200 megawatts of capacity and represents an investment of approximately $1.2 billion on its own. AI, tech, and the markets they move - in one daily briefing. Daily. Free. Join 34,000+ readers across crypto, finance, and policy. The loan is reportedly structured with a short 12-month tenor. Separately, the company announced plans to invest between S$3 billion and S$5 billion in next-generation digital infrastructure in Singapore, roughly $2.3 billion to $3.9 billion at current exchange rates. A competitive field with deep pockets. DayOne Data Centers is also reportedly in discussions for a significant expansion, with talks that could see an existing facility scaled up toward $7 billion. Bridge's pipeline already exceeds 1.5 gigawatts across facilities in Malaysia, Thailand, and India. What to watch. A 12-month tenor at this scale introduces refinancing risk, and the broader credit environment will matter considerably when the company returns to market for longer-duration capital. Bain Capital's majority ownership adds a layer of strategic context. When multiple well-capitalized operators are simultaneously racing to lock up power capacity, land, and anchor tenants in the same markets, the risk of oversupply in specific submarkets rises.
