AirTrunk has announced plans to invest MYR12 billion (USD3 billion) to develop two new hyperscale data centre campuses in Johor Bahru, Malaysia, to be called JHB3 and JHB4.
The two new campuses are planned for Iskandar Puteri in Johor and are expected to add more than 280 megawatts (MW) of combined IT load. AirTrunk said the sites will be located near its existing JHB1 and JHB2 campuses.
With the additions, AirTrunk’s Malaysia platform would exceed 700MW across four campuses, and the company said total committed investment in Malaysia would reach approximately MYR27 billion (USD6.8 billion).
AirTrunk said JHB3 and JHB4 are intended to support high-density cloud and AI workloads. The company said the facilities will include “advanced cooling systems” using 100% recycled water, and designs aimed at energy efficiency, although it did not provide specific performance metrics.
The announcement follows AirTrunk’s earlier disclosure of its JHB2 campus in early 2025. AirTrunk said its existing JHB1 and JHB2 campuses total more than 420MW of IT load and are almost fully contracted.
AirTrunk said it has awarded MYR423 million (USD107 million) to local suppliers so far, and expects that figure to grow to MYR5 billion (USD1.3 billion) when all four campuses are completed.
Robin Khuda, Founder & CEO of AirTrunk, said: “JHB3 and JHB4 represents the next phase of our expansion in Malaysia, building on the strong momentum of our existing Johor platform. Malaysia has set a clear ambition to lead in AI, and we’re investing in that vision for the long term, both within Johor and across the country in time. Our confidence comes from the strong partnership we have with the Malaysian Government and local stakeholders, who have supported us every step of the way. As we scale, the way we grow will matter as much as the trajectory. With that investment comes a responsibility to support communities, manage resources wisely, and embed that in how we plan, build and operate every day.”
Malaysia’s Deputy Prime Minister and Minister of Energy Transition and Water Transformation, YAB Datuk Amar Haji Fadillah bin Haji Yusof, said: “Malaysia is committed to strengthening its position as a leading digital and AI hub in the region. Our ambition is to be at the forefront of the digital and AI economy, supported by strong infrastructure, a robust ecosystem and responsible development in digital infrastructure. Investments like AirTrunk’s Johor expansion reflect growing confidence in Malaysia and play an important role in advancing innovation, talent development and long-term economic benefit for both the community and the environment. We welcome AirTrunk’s data centre investment that align with our vision of efficiency, sustainability and the use of clean energy.”
Australia’s High Commissioner to Malaysia, Danielle Heinecke, said: “AirTrunk’s investment is a good example of how Australia and Malaysia are working more closely together in building digital infrastructure. It supports Malaysia’s growth in the digital economy while also strengthening the connection between our two countries.”
AirTrunk said the development of JHB3 and JHB4 is expected to create more than 3,000 construction jobs, with ongoing employment once operational. The company also outlined education and community initiatives in Johor, including STEM scholarships with Universiti Teknologi Malaysia, clean drinking water projects with Gravity Water and Water Watch Penang, and flood resilience efforts with MERCY Malaysia.
The Malaysia expansion follows AirTrunk’s announcement of entry into India, which the company said is supported by a planned near-term investment of more than USD5 billion.
