Firmus, the Nvidia-backed AI data center operator, has pulled its planned Australian share market listing after investors balked at the price. The company withdrew its application to list on the ASX on Friday, October 9, 2026, according to ABC News, ending what would have been the largest Australian float since Telstra in 1997.

The Numbers Behind the Withdrawal

The offer targeted a valuation of about A$44 billion and a raise of about A$7 billion, according to a UniSuper investment update quoted by ABC. The offer price was A$11 a share, reportedly cut to A$8.25 with a smaller offering the day before the withdrawal. The books were closed to investors abruptly the night before, reportedly while the company was still pricing lower. Reuters had put the IPO at more than US$5 billion.

Firmus cited “recent market volatility and conditions” and said the offer would not appropriately reflect its long-term growth prospects. Nvidia holds a 7.2 percent stake in the company.

Why Investors Said No

Investors pulled back over the high price, concerns about an AI bubble and questions about the company’s leadership, ABC reported. Morningstar’s Lochlan Holloway focused on debt. “The neo-clouds are heavily geared,” he wrote, describing a model of borrowing against customer contracts to buy chips.

Firmus expects roughly US$30 billion (A$43 billion) of debt once its data centers are built. That is about six times the US$5 billion in operating earnings it forecasts for 2028.

A Pointed Verdict From a Large Investor

UniSuper’s chief investment officer, John Pearce, called the withdrawal disappointing. He said Firmus has “a compelling story” but not “a compelling valuation.” Pearce said the valuation was “priced to perfection” and worried that Firmus would need repeated debt and equity raises to fund expansion. UniSuper would not invest directly in the float but would likely hold shares through index strategies if it went ahead.

The company also lost a planned partner. CDC, which had planned to build data centers with Firmus, scrapped the deal. Its chief strategy officer, Jack Dan, told a federal parliamentary inquiry into AI that Firmus’s business model had “since evolved” away from its original focus on sovereign AI capability in Australia.

What Firmus Is Building

Firmus says it has seven AI factories across four countries: Australia, Singapore, Indonesia and Malaysia. Two sites are operational, in Australia and Singapore, and five are under development, targeting ready-for-service within 24 months. It is building AI data centers in Tasmania, where most planned centers are not yet built.

The company said it will pursue private market funding and consider other options, and that it will give shareholders more information as those options progress.

What It Means for Neo-Cloud Financing

The withdrawal tests a financing model that has carried much of the AI infrastructure boom: borrow against signed customer contracts, buy chips, and ask public markets to pay a premium for growth. When a company with an Nvidia stake and a debt load of six times its forecast operating earnings cannot find buyers at its asking price, other neo-clouds that plan to list will face tougher questions about leverage.

Larger players hold the advantage. Hyperscalers such as Microsoft, Amazon and Google have far larger balance sheets to fund AI capacity, and listed peers with long-dated leases, like Cipher at its Barber Lake campus, can point to contracted revenue. Firmus must now return to private investors, who may demand more proof before the next round.
