A listing that didn't happen
Firmus Grid is an AI infrastructure company backed by Nvidia, and it had been preparing to list on the ASX. The offering aimed to raise between A$5 billion and A$7 billion at a target price of A$11 per share, which implied an equity valuation of A$30.6 billion to A$43.7 billion. Back in August, Firmus had been valued at A$10.5 billion.
Then it pulled the deal.
Firmus withdrew its ASX IPO application on October 9. The company pointed to market volatility and demand it said didn't accurately reflect the potential of its business, as reported by Crypto Briefing.
Maas takes the hit
The selling in Maas started before the withdrawal was formalized. Maas shares fell 22.4% on October 8, wiping out approximately A$517 million in market capitalization in a single session, Crypto Briefing reported. Maas also entered a trading halt on October 8-9 as the Firmus situation unfolded, and Jefferies downgraded its rating on the company, according to the same report.
By the end of the week the stock was down more than 31%.
That's the largest weekly decline in the company's history.
What Maas actually has riding on Firmus
So how exposed is Maas? It holds a 3.2% stake in Firmus, secured through an A$300 million investment made in August 2026. Through its JLE subsidiary, Maas also has A$1.1 billion in work orders tied to modular power and electrical infrastructure for Firmus's AI projects (A$373 million of that has already been invoiced). Maas later confirmed that its contracts with Firmus remained intact.
Analysts cited by Crypto Briefing, who weren't named, said the sharp drop signaled genuine concern about the embedded value of the Firmus stake. Some commentators took the other side, criticizing the size of the selloff as excessive relative to the value adjustment they'd expect.
It's a sharp lesson in how a single private-market event can reprice a listed partner. Maas went from holding a slice of an AI infrastructure name priced for a multibillion-dollar float to absorbing a record weekly loss in a matter of days, while its contracts with Firmus, by its own account, haven't changed.
