Firmus Technologies pulls ASX float after $44bn listing collapses in five days

AI datacentre startup withdraws IPO amid concerns about early share sales and fading investor demand

Firmus Technologies, the Australian AI datacentre startup, has withdrawn its plans for one of the country's biggest ever stock market listings, just five days after the offer was launched. The IPO had been set to raise more than $7bn at $11 a share, valuing the company at $44bn, before promised investor demand evaporated.

Firmus Technologies has abandoned its planned ASX listing, ending a week in which a much-hyped offer went from apparent oversubscription to withdrawal. The company had promised investors a stake in an AI-enhanced future of liquid-cooled datacentres packed with Nvidia microchips.

According to The Guardian, citing multiple people briefed on the matter who asked not to be named, investment banks Morgans, Morgan Stanley, JP Morgan and Bank of America were managing the bookbuild. On Monday, the bankers' identical messages read: 'At the fixed price, indications are well in excess of the offer size.' The messages said 50% of the deal would go to existing strategic investors, meaning the company needed to raise about $3.5bn in new capital. Five retail brokers were also involved.

Behind the scenes, concerns emerged on Tuesday. Updated information showed that more than 50% of the register, including shares held by Wall Street firms Blackstone, Jane Street and Coatue, could be sold as soon as the company listed on 23 October. Even Oliver Curtis, who has spent time in prison for insider trading, could use a financial instrument to immediately monetise most of his stake despite being thought to have his shares locked up in escrow, the report said. His cousin Tim Rosenfield and former brother-in-law Jonathan Levee also stood to gain.

The company was valued at less than $2bn in 2025 and has just two small operational sites, making the $44bn asking price, roughly the size of Woolworths, an eye-watering step up.

By Friday, the float was off. The Guardian noted that retail investors may have been spared a potentially disastrous investment, and that attention now turns to claims made by Firmus's backers and the long-term viability of the business.

Analysis

Why This Matters

  • The collapse removes one of the largest tests of investor appetite for AI infrastructure on the ASX, after a valuation that had reached $44bn.
  • Retail investors who were encouraged to participate are no longer exposed to a stock that institutions had privately questioned.
  • The episode raises questions about how AI datacentre companies are valued and how quickly early investors could exit.

Background

Firmus was positioning itself as a direct play on the AI computing boom, with datacentres designed for liquid cooling and Nvidia chips. The company had been valued at less than $2bn in 2025, and its rise to a $44bn asking price made the float one of the most aggressive listings attempted in Australia. The week's events unfolded against a backdrop of intense enthusiasm for AI-related companies, but also growing scrutiny of whether their valuations can be sustained.

Key Perspectives

Firmus and its backers: They presented the offer as heavily oversubscribed, with bankers telling clients that indications were well in excess of the offer size at the fixed price, and with 50% of the deal taken by existing strategic investors.

Institutional investors: Several investment houses became concerned after seeing updated information showing that more than half the register, including stakes held by Blackstone, Jane Street and Coatue, could be sold immediately after listing.

Critics and skeptics: The valuation looked stretched for a startup with two small operational sites that was worth under $2bn in 2025. The Guardian noted that retail investors may have avoided a potentially disastrous investment.

What to Watch

  • Any announcement from Firmus about whether it will attempt a revised listing, seek private funding, or restructure the offer.
  • Whether the escrow and monetisation arrangements allowing early shareholders to sell quickly attract scrutiny.
  • The reaction of the investment banks involved, and whether other AI datacentre IPOs face similar investor doubts.
