Maas Group sells building materials unit for $1.19 billion to focus on AI infrastructure

Australia’s Maas Group announced the sale of its building materials division to Heidelberg Materials’ local arm for up to A$1.70 billion ($1.19 billion), marking a strategic shift towards artificial intelligence-related infrastructure. The conglomerate will invest A$100 million in Nvidia-backed Firmus Group for a 1.7% stake, causing its shares to plummet over 26% in their steepest one-day decline ever. The divestment reflects Maas Group’s broader move into data center construction, a sector gaining traction due to rising demand for AI support facilities. The transaction, expected to complete in late 2026, includes the transfer of 1,140 employees to HMA to ensure operational continuity.
