Maas Group secures $1.7 billion sale of construction materials division
Maas Group Holdings (ASX: MGH) has entered into a Share Sale Deed to divest its Construction Materials (CM) division to Heidelberg Materials Australia (HMA) for total cash consideration of up to $1.703 billion. The Maas Group Construction Materials Divestment includes $120.0 million in contingent payments linked to agreed post-completion operational and commercial milestones, with the transaction expected to complete in H2 CY2026.
The sale represents a valuation premium to MGH’s current trading multiple and exceeds recent comparable transactions within the construction materials sector. Heidelberg Materials Australia is a subsidiary of Heidelberg Materials AG, one of the world’s largest construction materials companies, providing strategic and operational strength to support the business post-transaction.
Approximately 1,140 employees are expected to transfer with the business, subject to completion. Certain freehold land assets will be retained by MGH and leased back to HMA under long-term commercial arrangements, creating an ongoing income stream for the group.
Transaction structure and key terms
The Share Sale Deed outlines the transfer of subsidiaries and other assets comprising the Construction Materials division, including Nationwide Machinery Sales (previously reported in the CC&H segment) and Yatala Quarry (previously reported in the CRE segment). Payment obligations are guaranteed by both Heidelberg Materials AG and Heidelberg Materials Australia Group Holdings Pty Ltd.
Completion of the transaction is subject to customary conditions, including approval from the Australian Competition and Consumer Commission (ACCC), the Foreign Investment Review Board (FIRB), MGH shareholders, and certain counterparty consents. MGH will prepare and dispatch a notice of meeting and explanatory memorandum to shareholders in due course.
The parties have committed to using best endeavours to agree on a transitional services agreement and joint migration plan to facilitate integration of the CM division into HMA’s operations.

The retention of freehold land with long-term lease arrangements provides MGH with ongoing revenue whilst transferring operational responsibility.

What is a corporate divestment and why do companies sell divisions?
A corporate divestment refers to the sale of a business unit or division to another company. Companies typically divest assets to unlock trapped value, refocus strategy on core operations, reduce debt levels, or redeploy capital into areas offering higher growth potential.
Divestments often occur when an asset holds greater strategic value to an external buyer than it does within the current corporate structure. In MGH’s case, the Construction Materials division is being sold at a premium to the group’s trading multiple, suggesting the market was undervaluing this division as part of the broader MGH portfolio.
Proceeds from divestitures can be used to strengthen balance sheets, fund expansion in priority business areas, or return capital to shareholders through dividends or share buybacks. For investors, divestitures signal management’s confidence in redeploying capital more effectively than maintaining the status quo.
Strategic pivot toward digital infrastructure and electrification
MGH has stated the divestment supports a deliberate repositioning from traditional infrastructure toward “next-generation” infrastructure opportunities. The group is focusing on three key strategic areas: digital infrastructure (high-density power, fibre-connected hyperscale data centres, and AI compute clusters), electrification (leveraging existing electrical businesses whilst selectively adding new capabilities), and industrial services.
This strategic shift mirrors MGH’s earlier positioning into renewables-related infrastructure and positions the group to participate in structural growth themes. The Australian data centre and electrification markets are described by management as presenting scalable, high-value opportunities aligned with MGH’s execution capabilities and programme-based delivery model.
As part of this strategy, MGH has made a strategic minority equity investment of $100 million for an approximate 1.7% interest in Firmus Grid Limited. Firmus is a vertically integrated developer and operator of next-generation AI infrastructure, focused on purpose-built platforms supporting high-density artificial intelligence workloads. The company is advancing a staged rollout of AI infrastructure campuses designed to support sovereign, large-scale compute requirements across Australia and internationally.
In December 2025, MGH’s JLE division secured a $200 million contract with Firmus to support the development of Project Southgate, a roadmap of critical sovereign AI infrastructure being built across Australia. The Firmus investment supports MGH’s long-term strategy to participate in the development and delivery of digital infrastructure assets whilst retaining capital discipline and operational flexibility.
If the transaction completes, MGH intends to use proceeds for the following purposes:
- Strengthen the group’s balance sheet and reduce net debt
- Support growth in electrical infrastructure capabilities, including leveraging existing businesses and selectively adding new capabilities
- Expand industrial services and infrastructure delivery operations
- Fund management and investment opportunities focused on digital infrastructure assets
- Consider potential capital management initiatives, including capital returns and share buybacks, subject to final transaction proceeds, post-transaction requirements, and approvals
Leadership commentary on the deal
CEO and Managing Director Wes Maas acknowledged the Construction Materials business built over many years, attributing its scale, quality, and performance to the commitment of MGH’s workforce. He expressed confidence that Heidelberg Materials is well-positioned to continue building on the division’s strengths, leveraging its global expertise and track record in delivering major infrastructure projects whilst providing continuity for the business and its people.
“This transaction allows MGH to crystallise value from a high-quality asset while positioning the Group toward the next phase of infrastructure investment, including digital infrastructure, electrification and AI,” Maas stated. “The sale enables a strategic re-focus and disciplined redeployment of capital into areas where we see strong structural tailwinds.”
Chairman Stephen Bizzell
“The Board is confident this transaction is in the best interests of shareholders. It crystallises value at a valuation significantly above benchmarks observed in comparable transactions.”
Bizzell also noted the transaction enables MGH to apply a disciplined capital allocation approach, consistent with the group’s track record of recycling capital when attractive valuations are available and redirecting capital to areas offering superior long-term returns. He confirmed proceeds will strengthen the balance sheet, reduce net debt, enhance financial flexibility, and allow the group to redeploy capital into growth opportunities, including digital infrastructure, electrification, and energy-transition related assets.
Shareholder approval and next steps
Wesley Jon Maas and Emma Margaret Maas currently hold and control the votes in relation to 178,758,133 MGH shares. The Maas shareholders have confirmed to the Board their intention to vote all of these shares in favour of the transaction. They have also committed not to sell, transfer, or otherwise dispose of these shares prior to the shareholder meeting convened for the purpose of approving the transaction.
A notice of meeting and explanatory memorandum will be dispatched to shareholders in due course, following satisfaction of certain other conditions precedent. The document will provide further details on the transaction and the resolutions to be considered at the shareholder meeting.
Completion remains subject to receipt of required regulatory approvals from the ACCC and FIRB, shareholder approval, obtaining certain counterparty consents, and implementing a pre-completion restructure. MGH has stated it will continue to update the market as approvals are obtained and strategic initiatives progress.
Outlook and what to watch
The transaction timeline extends through to H2 CY2026, with regulatory and shareholder approvals representing key milestones before completion. MGH shareholders should monitor the following developments as the transaction progresses:
- ACCC approval status and any conditions imposed
- FIRB approval timeline and determination
- Shareholder meeting date and voting outcome
- Final net proceeds after applicable purchase price adjustments
- Capital return announcements following completion
The Maas Group Construction Materials Divestment positions MGH to participate in structural growth opportunities across digital infrastructure, electrification, and AI-related infrastructure. Capital management initiatives, including potential buybacks or returns to shareholders, will depend on final transaction proceeds, tax outcomes, and the capital requirements of the post-transaction business.
