Nvidia-Backed Firmus Pulls the Plug on Australia's Largest IPO in Decades: It Wanted a $30 Billion Valuation, and Buyers Refused

The AI infrastructure boom just failed its first big public-market stress test. Firmus Grid, the Australian "AI factory" developer backed by Nvidia, withdrew its initial public offering on October 9 — walking away from what local press had billed as the country's largest float since Telstra in 1997 — after institutional buyers declined to pay the asking price, according to Bloomberg and Reuters reporting carried by CNBC.

The numbers tell the story. Firmus had pitched the listing at A$11 a share, implying an equity value of about A$43.7 billion, or roughly $30.4 billion, with the raise reaching as much as $5.5 billion including an over-allotment option. By the time the book closed on October 8 without a final clearing price, reports from the Australian Financial Review said the offer had already been cut toward A$8 — a drop of about 25 percent — with bankers trying to hold A$8.25. Late Thursday, the board chose to withdraw rather than keep cutting.

The company's statement was unusually direct: "Having considered recent market volatility and prevailing market conditions, the board determined that the terms on which the offer could proceed would not appropriately reflect the strength of the company's business and long-term growth outlook." Firmus will withdraw its listing application and pursue private capital instead, with Reuters reporting a later public sale — possibly in New York — remains an option.

What buyers balked at was the gap between the story and the arithmetic. Firmus began in 2019 as a bitcoin-mining operation before pivoting to liquid-cooled "AI factories" built on Nvidia hardware, and its valuation climbed vertiginously: a round led by Coatue in April put it near $5.5 billion, an August round that added Nvidia, Coatue, Blackstone and Jane Street lifted it to about $10.5 billion, and the October listing asked public investors to underwrite roughly three times the August figure. Documents seen by Bloomberg put the development pipeline near 912 megawatts — against only about 46MW actually built, spread across two small leased sites in Melbourne and Singapore. Annual revenue is roughly $51 million, and the draft prospectus forecast a $77 million loss for the first half of fiscal 2027 with no forecasts beyond June.

The debt picture was the quiet killer. Analysts working with the lead banks put Firmus borrowings near $30 billion. At the defended price of A$8.25, the equity value of roughly $23 billion would have sat several billion dollars below what the company owed lenders; at A$8 it was closer to $22 billion. Morningstar noted the debt ran to roughly six times the firm's own forecast earnings — a structure that works while capital is cheap and conviction high, and stops working the moment either wobbles.

The customer base is real, at least on paper: Firmus counts OpenAI and Meta among its customers, has an eight-year partnership with Nvidia, and is co-developing a Batam, Indonesia site with DayOne Data Centers expected to house 170,000 GPUs — a facility Meta expanded its Southeast Asia leasing commitments into this week. But the sentiment damage spread fast. Backer Maas Group fell as much as 30 percent in Sydney before a trading halt, and mid-week Reuters reported that CDC Data Centres' chief said on a podcast that a large joint development plan with Firmus was no longer going ahead. Ten Cap's Jun Bei Liu told Bloomberg Television she had "never seen an IPO so polarizing"; Morningstar's Lochlan Halloway pointed to a "wild increase in valuation in such a short period"; Merlon's Kirit Hara said his process stops him buying "hopes and dreams"; Katana's Romano Sala Tenna said the team was "struggling with the fundamental arithmetic"; and Plato called the stock a "screaming short," listing roughly 30 concerns.

The lesson generalizes well beyond one Australian prospectus. Private markets had been willing to fund the GPU-factory narrative at escalating marks because the rounds were small relative to the story; a public listing forced the same narrative to clear at scale, in daylight, against a pipeline that was 5 percent built. Hyperscalers locking up neocloud capacity — as Meta just did with Firmus across Southeast Asia — does not change the financing math, because the customers are committed to future capacity, not today's revenue. The first AI-infrastructure IPO of this cycle to reach a national market did not get repriced; it got withdrawn. Every other gigawatt-scale pitch heading for an exchange window just received its term sheet.
