Nvidia-Backed Data-Center Firm Scraps $5.5 Billion Australian IPO

Firmus, an Australian artificial-intelligence data-center developer backed by Nvidia, has abandoned a planned listing on the Australian Securities Exchange that would have ranked among the country's largest initial public offerings, after institutional investors declined to back the deal at its marketed price.

The company and its bankers closed the institutional bookbuild Thursday without securing enough demand at the offer price of A$11 a share, according to reporting on the collapsed sale. The planned raise, which included a greenshoe option, had targeted roughly US$5.5 billion, a sum that would have made it one of the largest IPOs ever attempted in Australia. Bankers had reportedly discussed cutting the price to around A$9 a share in a last attempt to save the deal before the offering was withdrawn entirely, according to an industry newsletter tracking the listing.

A soured partnership weeks before the float

The failed listing followed the collapse of a key construction partnership. CDC Data Centres pulled out of a planned joint buildout with Firmus, known internally as Project Southgate, with only a small fraction of the project complete, according to Australian trade coverage of the split. CDC's founder was reported to have said his company was unlikely to build further data centers for Firmus, while Firmus's own chief executive characterized the split as a mutual decision reached earlier in the year. Either way, the timing — weeks before a marquee share sale premised partly on Firmus's construction pipeline — unsettled prospective investors.

Nvidia had been among the highest-profile names behind Firmus, participating in a US$2.85 billion funding round in August that valued the company near US$15 billion, a figure its IPO price would have implied a far steeper valuation against. That gap between private and public pricing expectations became a central sticking point for institutional buyers weighing the offer, according to coverage of the bookbuild, which closed on schedule Thursday morning in Australia without a clear resolution on price.

The episode lands at a delicate moment for the broader data-center financing boom. Billions of dollars have poured into companies promising to build the physical infrastructure — power, cooling, and server halls — that AI models require, often financed through a mix of venture rounds, debt and, increasingly, public listings. Firmus's failure to clear the market at its asking price has been read by some analysts as an early signal that investors are growing more discriminating about which data-center operators can justify premium valuations, rather than a wholesale retreat from the sector.

For Firmus, the setback does not necessarily end its ambitions. Companies that pull IPOs frequently return to markets months or years later, sometimes at a lower valuation, and the company's underlying contracts and land holdings remain intact regardless of its public-market status. But the immediate consequence is a blow to a listing that had been positioned as a bellwether for how much appetite remains among ordinary investors for AI-infrastructure plays, at a time when hyperscalers and private financiers have already committed hundreds of billions of dollars to similar buildouts globally.

The Australian market, which has seen comparatively few large technology listings in recent years, had been counting on Firmus to help revive interest in local tech IPOs. Its withdrawal leaves the exchange's new-listings pipeline thinner and puts pressure on other AI-adjacent companies reportedly weighing Australian floats of their own in the coming year.
