Maas Group's Firmus Data Centre Deal Reshapes a Modest Growth Story

A construction materials divestment and a growing AI infrastructure contract are changing the setup, even as governance concerns keep some fund managers cautious.

13 Oct 2026 · 3 min read

Maas Group Holdings has become an unlikely AI infrastructure play through its JLE Group electrical subsidiary's contract with neo-cloud data centre operator Firmus Technologies, and a $1.7 billion sale of its legacy construction materials business has left fund managers debating whether the market has yet appreciated the strategic optionality that deal creates.

A modest growth story turns concrete

QVG Capital said Maas Group's December rally had nothing to do with the season, but everything to do with a $200 million contract for its JLE Group subsidiary to build substations for neo-cloud data centre player Firmus Technologies, making what had long been a questioned growth story considerably more concrete. QVG noted the stock had traded on a modest rating for good reason, given an unfortunate habit of missing earnings expectations and returns on invested capital that had lagged management's own targets. SG Hiscock and Company said the stock rose 19.8 percent in December following the roughly $200 million agreement between JLE Group and Firmus Technologies, covering electrical infrastructure for Firmus's data centre build.

Governance concerns hold back a data centre re-rating peers have enjoyed

Maple-Brown Abbott added Maas Group to its watchlist in May, drawn to Australia's structurally strong data centre build-out driven by hyperscaler investment, cloud migration and AI workloads, but noted the stock had lagged the strong share price performance of data-centre-exposed contractor peers given governance concerns while the market continues digesting its data centre exposure story.

A $1.7 billion construction materials sale reshapes the business

Wilson Asset Management, a core holder, said it added significantly to its position after Maas Group announced the proposed sale of its construction materials business. Firetrail Investments said the stock rose 16 percent in May after a trading update reconfirmed FY2026 underlying EBITDA guidance of A$250 million to A$280 million, with a more noteworthy update on the A$200 million Firmus contract to build a 100 megawatt AI Factory in Launceston, then 35 percent complete. Wilson Asset Management said that following the $1.7 billion sale of the Construction Materials business, it believes the market has significantly under-appreciated the strategic optionality created and the potential earnings uplift, arguing that with the share register now stabilised, the setup is much cleaner, with Maas Group's Firmus stake alone worth more than $1 per share.

What fund managers say they are watching next is completion of the $1.7 billion construction materials sale and deployment of the proceeds, continued build-out of the 100 megawatt Launceston AI Factory toward completion, resolution of the governance concerns Maple-Brown Abbott flagged, and whether the market eventually credits the more than $1 per share value bulls attribute to the Firmus stake.
