Maas Group 23% share fall|Firmus float risk to $1.2 billion contracts?

A float that turned in three days

Maas Group shares fell about 23 per cent on reports that Firmus, the AI data centre firm it part-owns, may cut its float price. But a lower Firmus price, applied to Maas's stake, explains only part of what the market took off Maas. Maas holds about 3.2 per cent of Firmus. Its subsidiary JLE also has more than $1.2 billion of electrical work tied to Firmus's AI factories.

Neither company has confirmed a change to the offer price. One headline put the sell-off down to investors marking down Maas's stake. It is better read as a bet on whether Firmus lists at all, and keeps paying for the work Maas does. Three days before the sell-off, a book update sent to fund managers said interest in the Firmus float was “well in excess” of the offer size.

The price had been set at $11 a share, valuing Firmus at about $43.7 billion. The bankers even brought the book close forward a day, because early bids exceeded the initial offer size. At that size, it would have been the second-largest float in Australian history, behind only Telstra in 1997. The day before the sell-off, the banking syndicate began discussing a lower price with big investors.

People briefed on the matter said overseas demand overnight had come in lower than expected. Some investors saw the pricing as aggressive, and feared existing shareholders could flood the market soon after listing. Only two of Firmus's data centres are operating. The rest are still being planned or built. Reports first put the new price at around $9.

As the book closed, the Financial Review and the Sydney Morning Herald reported about $8.25. The Australian, citing market sources, went further. It reported that Firmus and its advisers were believed to be pulling the float, after lobbying Nvidia overnight for more financial support. The Financial Review reported that the offer documents were pulled from the data room used by fund managers.

Bloomberg reported that neither a price cut nor a withdrawal had happened so far. So the cut is widely reported, but not confirmed. Maas holders face two branches: a float at a lower price, or no float at all.

What the stake can explain

Start with the reading that this is a stake markdown. Maas has invested $410 million in Firmus in total, for about 3.2 per cent. That values the whole of Firmus at roughly $12.8 billion. On Nine's calculation, $8.25 a share would value Firmus at about $32.8 billion, on the same share count. So even the lowest reported price values Firmus at around two and a half times the level Maas bought in at.

Now the size of the cut. The offer price was $11. A cut to $8.25 takes a quarter off it. Apply that to Maas's 3.2 per cent, measured against Firmus's whole valuation. The most the stake could lose is about $350 million. The Financial Review put Maas's early loss at about $550 million. That leaves roughly $200 million of the fall that the stake price cannot explain. The stake also reaches Maas's earnings.

Maas has lifted the value of its Firmus holding based on Firmus's latest capital raising and secondary-market prices. In August, its full-year earnings guidance included that fair value uplift. In September, it scrapped guidance altogether, citing too much volatility in its revenue streams. So the Firmus price now flows into what Maas reports, in either direction.

But it flows through the same 3.2 per cent, so the limit worked out above still holds.

What Maas has become

The second exposure is work. In August, Maas confirmed an $855 million order from Firmus for modular electrical infrastructure, due over 18 months. That lifted JLE's electrical work in hand to more than $1.2 billion. Under a master services agreement, JLE is the exclusive supplier of power train units for Firmus's Australian pipeline. That work began with Firmus's 100 megawatt AI factory at Launceston, in Tasmania.

At the same time, Maas is selling its construction materials division to Heidelberg Materials for up to $1.7 billion in cash. The Financial Review described it as selling more than half the company to gain greater exposure to AI. Maas has said settlement is on track for October. Excluding that division and the Firmus revaluation, it guided its other businesses to $130 to $135 million of operating earnings, or EBITDA.

When Maas shares jumped 8 per cent in September, the Financial Review tied the move to the $1.2 billion pipeline and the Firmus stake. Those same two things now pull the other way. The extra $200 million is better read as a discount on the work than on the stake.

Two readings of one bet

Maas chair Stephen Bizzell set out the pivot at the company's annual general meeting. He said Maas “took meaningful steps to increase its exposure to next-generation infrastructure”. He called it “a clear evolution in the Group's strategic direction”. Oscar Oberg of Wilson Asset Management, whose firm holds shares in both Maas and Firmus, described the same exposure.

“The whole business is totally exposed to Firmus, operationally and through its investment.” He also said: “We're in the dark here. The stock's gone off newspaper articles.” Answering an ASX query, Maas put the slide down to speculation about whether the Firmus float would proceed. It also said it had no undisclosed information that would explain the selling. Neither voice disputes the exposure.

And Maas's own explanation names the risk as whether the float goes ahead, not the price. Oberg added: “The market's shooting first.” If so, part of this fall is a price for not knowing, rather than a measured loss. In August, the Financial Review reported Wilson trimming its Firmus stake as Maas Group loaded up. The two sides of that trade now share the same blind spot.

If the float falls short

A pulled float would not leave Firmus without backers. Nvidia holds 7.2 per cent, and is reportedly involved in its funding as well as supplying its chips. Backers including Nvidia and Blackstone had already committed $2 billion. A book update said about half the float was to go to existing backers. And The Australian reported the advisers had lobbied Nvidia for more support.

Firmus's money does not depend only on new investors paying $11. But that $2 billion of commitments was reported as buying GPUs for Firmus's first data centre project, in Batam, Indonesia. Firmus is also shifting its growth focus towards Southeast Asia, including Malaysia. In the same week as the bookbuild, its rollout partnership with CDC Data Centres ended. JLE's exclusive role covers the Australian pipeline.

In Tasmania, Firmus's $2 billion St Leonards factory is due to start operating in early 2027. So the question for Maas is narrower than whether Firmus survives. It is whether Firmus's money keeps flowing to Australian sites. A repriced float alone would not settle that.

Reading the fall

On the float itself, the evidence leans one way. The Financial Review reported the book closed after the syndicate worked overnight to salvage the deal at about $8.25. The Australian reported the advisers were cutting their fees, and that Firmus might be valued as low as $30 billion. Against that, Firmus was not on the ASX page of upcoming floats.

The ASX says the page is usually updated within three business days of a formal application. Taken together, a float at a lower price looks more likely than no float. That is a judgment, not a confirmed outcome. Back to the gap in Maas's fall. The Financial Review put it at almost a quarter of the company's value. The stake price explains at most about $350 million of it.

The rest is best read as a discount on whether Firmus keeps funding the Australian factories JLE supplies. If Firmus lists, even near $8.25, the stake stays well above what Maas paid. What stays open is the Australian order book. The signal to watch is whether Firmus confirms a final offer price and keeps its October 23 listing.

If it does, the question of whether the float happens is settled, and Maas's exposure narrows to the Australian work. If Firmus withdraws, Maas is left with an unlisted stake and no market price for it. Its order book would then rest on backers Maas does not control.
