MGX in talks to acquire DayOne for multi-billion-dollar Singapore data center foothold

Abu Dhabi's MGX is in advanced discussions to acquire DayOne, the Singapore-based data center operator serving AI compute workloads, in a transaction expected to exceed $2 billion. The deal would mark MGX's first infrastructure acquisition in Asia and the sovereign vehicle's largest single-asset commitment since its $100 billion capitalization was announced in October 2024.

DayOne operates one production facility in Singapore's Tuas district, a 48-megawatt hyperscale site commissioned in late 2022. The asset runs GPU clusters for regional AI training workloads, with Nvidia H100 and A100 configurations occupying roughly 70 percent of rack capacity as of January 2025. Singapore's moratorium on new data center construction — imposed in 2019 and partially lifted in 2022 for sustainability-compliant projects — makes existing facilities with power allocations trading at material premiums. DayOne holds a provisional 96-megawatt expansion permit, subject to energy-efficiency benchmarks the facility has not yet met.

MGX was established as a joint venture between Mubadala Investment Company, G42, and sovereign entities to consolidate Abu Dhabi's AI infrastructure and semiconductor bets. The vehicle has committed capital to Cerebras Systems, OpenAI, and undisclosed stake-building in hyperscale colocation operators across the U.S. and Europe. A Singapore acquisition extends that strategy into Southeast Asia's constrained supply environment, where rack scarcity and regulatory friction have pushed lease rates 40 percent above U.S. Gulf Coast equivalents. The DayOne transaction would also position MGX inside the ASEAN digital economy framework, allowing co-location partnerships with regional cloud providers without triggering foreign-investment reviews in Jakarta or Kuala Lumpur.

The valuation mechanics are unusual. DayOne's trailing EBITDA is estimated near $180 million, implying a purchase multiple above 11x if the deal closes at $2 billion. Comparable transactions in 2023 — Digital Realty's acquisition of Teraco in South Africa, Brookfield's purchase of a stake in AirTrunk — traded between 8.5x and 9.2x EBITDA. The premium reflects two factors: Singapore's regulatory moat, and MGX's apparent willingness to pay for time rather than yield. Sovereign capital with a 20-year horizon prices assets differently than pension allocators managing duration-matched liabilities. MGX is buying positioning, not cash flow.

Allocators should monitor three follow-on events in the next 90 days. First, whether MGX secures the 96-megawatt expansion permit, which requires demonstrating 1.3 PUE or better and participation in Singapore's green-energy certificate program. Second, whether DayOne's existing anchor tenants — believed to include a Tier-1 hyperscaler and two regional AI labs — exercise lease-extension options that would lock capacity through 2029. Third, whether MGX syndicates equity to regional co-investors. G42 has historically partnered with Malaysia's Khazanah Nasional and Indonesia's INA on cross-border infrastructure. A syndication round would signal MGX is building a pan-ASEAN platform, not making a standalone bet.

The transaction is not yet binding. No exclusivity period has been disclosed, and DayOne's shareholders — a consortium including Temasek Holdings and an unnamed U.S. pension fund — have not formally approved a sale process. But the talks are advanced enough that MGX has engaged infrastructure advisors in Singapore and retained legal counsel with experience navigating the Singapore Land Authority's approval regime for foreign-controlled critical infrastructure. The deal either closes by late Q2 2025, or it fractures on permit risk and valuation disagreement. There is no patient middle ground when sovereign capital meets a moratorium-protected asset.
