Full summary

The Australian Competition and Consumer Commission (ACCC) has approved Heidelberg Materials Australia Holdings Pty Ltd's acquisition of Maas Group Holdings' construction materials business, subject to conditions. Heidelberg must divest three concrete plants and a quarry in Queensland and New South Wales to address competition concerns. The ACCC found that without these divestitures, the acquisition could substantially lessen competition in certain regions. This marks the first Phase 1 Decision with conditions since the new merger control regime commenced on January 1, 2026.
