Maas Group Holdings (ASX: MGH) has completed the sale of its Construction Materials business to Heidelberg Materials Australia, receiving A$1.61 billion at completion in October 2026. The payment comprises the purchase price and estimated completion adjustments. Up to a further A$120 million remains contingent on agreed operational and commercial milestones.
What Maas Group received
Maas Group’s 2 October 2026 ASX announcement, as reported in the completion report, records A$1.61 billion received when the transaction settled. That figure is the cash delivered at completion, not the maximum value announced when the deal was signed.
The original 5 February 2026 announcement described a transaction worth up to A$1.703 billion. The headline amount included A$120 million of contingent consideration, payable only if specified milestones are achieved. The difference between the announced maximum and the completion payment therefore reflects both the contingent structure and completion adjustments; the available completion information does not provide a final breakdown of each adjustment.
| Measure | Amount or status | What it means |
|---|---|---|
| Cash received at completion | A$1.61 billion | Purchase price plus estimated completion adjustments, received by Maas Group in October 2026 |
| Announced maximum transaction value | Up to A$1.703 billion | Headline value announced on 5 February 2026, including contingent consideration |
| Contingent consideration | Up to A$120 million | Additional amount conditional on agreed operational and commercial milestones |
No final allocation of the proceeds among debt repayment, buybacks, reinvestment or other uses has been disclosed in the material accompanying the completion report.

Who bought the business
The buyer is Heidelberg Materials Australia Holdings Pty Limited, part of Heidelberg Materials. Its earlier agreement release put the target’s enterprise value at about A$1.7 billion and described it as a major eastern-Australian supplier of aggregates, ready-mixed concrete and asphalt.
Heidelberg Materials Australia CEO Phil Schacht said the company was welcoming the new colleagues and highlighted the acquired team’s regional expertise, customer relationships and operational capability. He said the immediate focus was a smooth transition while maintaining safe, reliable operations and existing service standards.
What Heidelberg Materials acquired
The transaction covers a large construction-materials network across New South Wales, Queensland, Victoria and the Australian Capital Territory. Heidelberg Materials says the acquired operations comprise:

The quarries have combined reserves of more than 350 million tonnes. The business supplies aggregates, ready-mixed concrete, asphalt and recycled construction materials to customers across eastern Australia.
| Asset or measure | Transferred footprint |
|---|---|
| Quarries | 43 |
| Ready-mixed concrete plants | 22 |
| Asphalt operations | 5 |
| Recycling sites | 1 |
| Combined quarry reserves | More than 350 million tonnes |
| Employees | Approximately 1,140 transferred |
Employees, customers and brands after settlement
Approximately 1,140 employees transferred with the business. Heidelberg Materials stated that no workforce reductions were planned as a result of the acquisition. It also said existing businesses and brands would continue operating as they do today, while customers and suppliers would keep working with their existing contacts.
Those statements describe the planned operating approach at completion; they are not a guarantee that staffing, branding or contact arrangements can never change as integration proceeds.

How the deal progressed to completion
- 5 February 2026: Maas Group announced the proposed sale at up to A$1.703 billion, including up to A$120 million in contingent consideration.
- Regulatory and shareholder process: The transaction was subject to Australian Competition and Consumer Commission (ACCC) and Foreign Investment Review Board (FIRB) approvals, as well as Maas Group shareholder approval.
- 18 May 2026: Maas Group reported that the sale was progressing through regulatory approvals and remained on track for settlement during calendar 2026.
- October 2026: The sale completed, and Maas Group reported receiving A$1.61 billion at completion.
Completion means the agreed business and assets have transferred to Heidelberg Materials, but the contingent consideration remains a separate, future possibility rather than settled proceeds.
Why the transaction matters
For Heidelberg Materials, the acquisition expands its quarry, concrete, asphalt and recycling presence across four eastern Australian jurisdictions. The scale of the reserves and the number of downstream plants give the buyer additional regional production capacity and established customer relationships.
For Maas Group, the sale converts the Construction Materials business into a large cash receipt while leaving the final contingent amount dependent on future performance against agreed milestones. The completion figure should therefore be used when discussing cash received, while A$1.703 billion applies only to the original maximum transaction value.

The Bottom Line
Maas Group received A$1.61 billion when Heidelberg Materials Australia completed its purchase of the Construction Materials business in October 2026. The original deal was worth up to A$1.703 billion because as much as A$120 million remains conditional on future milestones; the transferred network includes 43 quarries, 22 concrete plants, five asphalt operations, a recycling site and approximately 1,140 employees.
