Mah Sing Sells 78.8 Acres in Selangor to DayOne for RM617.9M — Malaysia's AI Build-Out Moves Past Johor

Malaysian property developer Mah Sing Group has agreed to sell 78.8 acres (31.89 hectares) of commercial land in Sepang, Selangor to WG Malaysia X Sdn Bhd, a subsidiary of DayOne Data Hub II Sdn Bhd, for RM617.9 million (about $152.8 million) in cash. The sale-and-purchase agreement, disclosed in a Bursa Malaysia filing on August 20, 2026, covers vacant land within Mah Sing’s Southville City township and marks DayOne’s first confirmed Malaysian site outside its existing Johor campus.

What is known

Mah Sing’s wholly owned subsidiary, Southville City Sdn Bhd, is the seller; the land sits within the company’s “Mah Sing DC Hub @ Southville City” project in Sepang, near Kuala Lumpur International Airport. The buyer, WG Malaysia X, is a subsidiary of DayOne Data Hub II Sdn Bhd, itself part of DayOne — the data center platform that spun out of China’s GDS Holdings in 2025 with backing from SoftBank Vision Fund, Coatue, Baupost and Citadel’s Ken Griffin. The Edge Malaysia and The Star both reported the RM617.9 million price, worked out at roughly RM180 per square foot; w.media converts that to approximately $152.8 million.

Per the DCD and Star coverage of the filing, Mah Sing said the buyer has expressed interest in bringing “NeoCloud and advanced Nvidia GPU computing capabilities” to the site alongside data center development and operating expertise, targeting high-performance AI workloads. Mah Sing founder and group managing director Tan Sri Leong Hoy Kum framed the sale as building “a meaningful second growth engine” for the company, adding that the deal contributes to “Malaysia’s ambition to become a leading regional hub for AI and digital infrastructure.” Mah Sing said proceeds will fund remaining infrastructure works at Southville City, working capital, and further moves in its digital infrastructure strategy — which reportedly also includes talks with a colocation operator to develop the broader hub, described as still at a preliminary stage.

No completion date has been disclosed; The Edge Malaysia reported the agreement was signed Thursday, August 20, 2026, with no closing timeline specified in the filing as reported.

What it means for a power buyer

This deal opens a Malaysian AI campus location outside the two clusters our Malaysia catalog already tracks in depth — Johor’s Kulai, Johor Bahru and Iskandar Puteri corridor, and the older Cyberjaya enterprise cluster near Kuala Lumpur. Sepang sits closer to KLIA than to either, and none of the 30 Malaysian facilities Coloprice currently tracks is sited there — this would be the first.

The timing lines up with Malaysia’s February 2026 policy that froze approvals for non-AI data centers while keeping the door open for AI-purpose projects (see our coverage of that freeze). A GPU-first campus is exactly the kind of project the carve-out was designed to admit, and it signals that developers are actively working the AI exception rather than treating the freeze as a blanket pause. For buyers comparing Malaysian sites, our colocation price index currently uses $0.129/kWh as Malaysia’s reference commercial power tariff — roughly half Singapore’s — but a greenfield land deal like this one says nothing yet about power allocation, energization timeline, or rack pricing at the site; those typically lag a land purchase by a year or more in Johor’s build-out pattern, and there is no reason to expect Sepang to move faster.

DayOne’s own history is the more useful signal than the land deal alone. Its Johor campus (Nusajaya Tech Park) opened in 2023 roughly 14 months after groundbreaking, using prefabricated construction; its Singapore, Thailand and Indonesia sites have each taken shape over 12-24 months from announcement to first power. If Sepang follows a similar cadence, first capacity is unlikely before 2027-2028 — a timeline worth checking against our Southeast Asia catalog as the project progresses.

What we don’t know

Mah Sing’s disclosure and the press coverage of it do not include a power capacity figure, building count, floor area, or construction start date for the Sepang site. The identity of the eventual colocation operator — if Mah Sing’s separate partnership talks proceed — has not been named. It is also unclear whether DayOne intends to develop and operate the site directly under its own brand, as it has done in Johor and Singapore, or in the joint structure Mah Sing described. Until a groundbreaking or a power purchase agreement is announced, Sepang remains a land transaction rather than a data center project with a confirmed timeline.
