Nvidia-Backed Firmus Cancels $5 Billion Australia IPO Amid Market Doubts

Firmus, an AI-focused data centre operator with backing from technology giant Nvidia, has withdrawn its planned $5 billion initial public offering (IPO) in Australia. The decision, announced on Friday, highlights growing investor skepticism toward the valuations and long-term viability of large-scale investments in artificial intelligence infrastructure.

The company revealed it will now pursue private funding instead, with plans to eventually list on the Nasdaq stock exchange, according to an anonymous source familiar with the transaction. Firmus has not publicly confirmed this potential move.

Had it proceeded, Firmus' IPO would have ranked as the second-largest share sale ever on the Australian Securities Exchange, underscoring the significance of this withdrawal. Demand from investors was tepid, signaling increasing selectivity in AI-related offerings amid a wave of fundraising efforts across both debt and equity markets.

In a letter to shareholders, co-founders Oliver Curtis and Tim Rosenfield said, "The company will now pursue capital from private markets and consider alternative international public market options to support its next phase of growth." They added, "We will continue to assess opportunities that provide the best platform to fund growth, create value and position Firmus for success."

Firmus designs and operates modular AI data centres that utilize proprietary energy and cooling technologies. Its investor roster includes major players such as Nvidia, Coatue Management, Blackstone, and Jane Street. The IPO was highly anticipated, expected to be the fourth-largest global public offering so far this year, trailing only SpaceX, CXMT Corp, and Cerebras Systems, according to Dealogic data.

The cancellation represents a setback for the Australian capital markets, which have experienced a decline in new listings and a shrinking number of publicly traded companies in recent years.

Concerns mounted after reports surfaced that a key partner, CDC Data Centres, withdrew from a substantial A$73 billion data centre development project with Firmus. CDC's CEO Greg Boorer mentioned on a podcast that the plan to develop 1.6 gigawatts of AI factories in collaboration with Firmus was no longer proceeding, dampening investor enthusiasm.

Initially, Firmus targeted a share price of A$11, valuing the company at approximately $30.6 billion—almost three times higher than the $10.5 billion valuation achieved during a fundraising round at the start of August. Investors grew wary of the company's heavy debt load, reported to be around $30 billion, and its lack of an extensive track record in constructing AI data centres.

Firmus currently operates two leased data centres in Melbourne and Singapore and has plans to build five additional facilities across the Asia-Pacific region. The company's draft prospectus projected annual earnings of $5 billion within five years, relying on the performance of these data centres.

Joseph Koh, a portfolio manager at Blackwattle Investment Partners, explained that the market was hesitant to endorse such a high valuation based on future expectations that assumed nearly flawless execution. "The market wasn't comfortable taking that leap of faith quite at this stage yet," he said. Koh's firm considered the IPO but ultimately chose not to participate.

Investor interest initially appeared sufficient to cover the IPO, with the book managers sending the term sheet just days before the planned launch. However, enthusiasm waned rapidly after the CDC announcement and concerns about escrow arrangements allowing a significant portion of shares to be sold by existing investors immediately upon listing. Such conditions raised fears about the potential impact on Firmus' stock performance in the early trading period.

Rather than reduce the share price, Firmus decided to shift focus to private funding, reportedly exploring the possibility of raising up to $3 billion from current shareholders. The company has not commented on these plans.

Oscar Oberg, lead portfolio manager at Wilson Asset Management and an investor in Firmus since last year, described the situation as disappointing. "Three days ago we thought it was all going well... The market has spoken," he said.

Bank of America, JPMorgan, Morgan Stanley, and the Australian broker Morgans led the IPO bookbuilding effort.

With the company's enterprise value estimated at $60 billion when factoring in debt, Firmus would have been among the largest publicly traded companies in Australia, surpassing many long-established firms.

Jun Bei Liu, co-founder of fund manager Ten Cap, viewed the aborted IPO as a reflection of a broader reassessment among investors regarding AI infrastructure investments. "The Firmus situation represents an important reality check for the AI investment boom," Liu stated, though she emphasized it did not signal the end of AI investment enthusiasm. She pointed to specific challenges surrounding Firmus, including the rapid increase in valuation, significant capital demands, and execution risks tied to its aggressive expansion plans.

Globally, major technology corporations such as Nvidia and SpaceX continue to access debt markets for tens of billions of dollars, while AI startup Anthropic is reportedly aiming to raise up to $100 billion in an IPO.

Investor concerns about AI returns have been echoed in recent market movements. Despite chipmakers surging over 80 percent this year, they dropped 3.4 percent on Thursday following media reports indicating that OpenAI's annualized revenue for September was around $50 billion, lower than earlier estimates.

The Firmus episode illustrates the challenges AI infrastructure companies face in convincing investors that lofty growth forecasts and capital-intensive business models can translate into sustainable financial success.
