What Is Happening With The Firmus IPO?

What was shaping up to be the most consequential Australian IPO in nearly three decades looks to have hit something of a wall, with institutional markets emphatically rejecting the A$11.00 offer price that underpinned Firmus Technologies’ float, forcing underwriters to look for a deal that can actually get done.

The fallout from the Firmus repricing saga has been swift and painful, extending well beyond the company itself. Shares in Maas Group Holdings (ASX: MGH), a company with more than A$1.2 billion in electrical contract work tied to Firmus data centre projects fell back 22.38% today as markets priced in the risk of the float being significantly downsized or abandoned altogether.

The reaction in the MGH share price is the clearest real-time signal of how seriously markets are treating the uncertainty. For a company whose near-term revenue pipeline is materially linked to Firmus breaking ground on new facilities, a delayed or restructured IPO is a threat to earnings visibility.

The company also holds a 3.2% equity stake in Firmus, having committed more than A$300 million in August through a combination of ordinary and preference shares priced at A$230 each, with total exposure estimated at between A$300 million and A$410 million. At the originally proposed IPO price of A$11 per share, analysts had estimated that Maas’s stake contributed roughly A$4.00 per share of implied value to MGH’s own share price. A$1.43 coming off of MGH on the day sits in percentage terms between the potentially discounted level that Firmus may price at.

The Firmus IPO itself remains in a state of uncertainty, but not suspended. Today’s news that lead joint managers at Bank of America, JPMorgan, Morgan Stanley, and Morgans closed the institutional bookbuild early without announcing a final price or confirmed deal structure was not well received by markets. But there remain reports that the offer price could still be amended lower to make the float move forward.

From Mega-Float to Damage Control

The scale of the reversal is striking, with Firmus marketing shares at A$11.00 each this month, targeting a capital raise of between US$4.9 billion and US$5.5 billion, inclusive of over-allotment options. Had it priced at those levels, the listing would have been Australia’s largest since Telstra’s landmark A$10 billion float in 1997.

Instead, underwriters are now working toward a revised offer price in the range of A$8.25 to A$9.00 per share, a cut of approximately 18% to 25% from the original A$11.00 target, alongside a meaningfully reduced capital raise of around US$3.5 billion to US$4.0 billion. A revised prospectus is expected to be lodged early next week (October 12), with the retail offer period scheduled to run from October 12 through October 19. The anticipated ASX debut remains pencilled in for October 23, 2026, though that timeline is dependant on underwriters securing sufficient final orders at the discounted price.

The core tension at the heart of this deal is a valuation that asked public markets to make an enormous leap of faith. Firmus completed a private funding round as recently as August 2026 at a post-money valuation of US$10.5 billion. Seeking a US$30.6 billion valuation just two months later generated immediate resistance from U.S. long-only fund managers, whose anticipated orders failed to materialise at the A$11.00 level.

That resistance is rooted in fundamentals. Firmus currently operates just 42 megawatts of live data center capacity, split across facilities in Melbourne and Singapore. Its growth thesis rests on an ambitious pipeline targeting 1,000 megawatts (1 gigawatt) of capacity across Australia, Southeast Asia, and new projects in Batam, Indonesia, and Malaysia. The gap between 42 MW of running infrastructure and a 1,000 MW buildout plan is precisely the kind of execution risk that institutional markets, particularly U.S. long-only funds with strict valuation discipline, are unwilling to underwrite at a premium multiple.

Adding to the pressure is the company’s capital structure. Analysts have flagged that Firmus is projected to carry approximately US$30 billion in debt to fund its multi-country capital expenditure program, a debt load that leaves the company acutely exposed to sustained high global interest rates and any deterioration in credit market conditions.

Why the Deal Still Has Supporters

Despite the turbulence, the Firmus float has not been abandoned, with some clear reasons. The company’s cap table reads like a who’s who of global technology and private capital. Nvidia, Blackstone, Coatue Management, Jane Street, and Silver Lake are all existing backers, and existing institutional holders had reportedly agreed to take up to 50% of the total IPO allocation, a meaningful anchor that provides underwriters with a foundation to build from even at a reduced price.

The customer roster includes Meta, OpenAI, and an eight-year strategic partnership with Nvidia, positioning it as a genuine regional infrastructure backbone for AI compute workloads. The company’s pathfinder prospectus forecast revenue approaching US$13 billion and EBIT of between US$5.75 billion and US$5.8 billion by FY28 or FY29, underpinned by contracted demand for regional AI compute infrastructure across Asia-Pacific markets that remain significantly undersupplied relative to the United States and Europe.

The Firmus situation is a case study in the gap between private market valuations and the discipline that public markets impose. The AI infrastructure boom has generated extraordinary valuations in venture and private equity circles, but long-only funds whose participation is critical to a deal of this size apply a different framework.

What Next?

At A$8.25 per share, the implied market capitalisation falls to roughly A$32.8 billion, but whether that revised price is sufficient to clear the institutional book remains the question heading into Monday’s expected prospectus lodgement. The narrative behind the listing has changed however, as an IPO that arrives at a discounted price after a public repricing carries a different tone than one that prices cleanly and opens strong.

The October 12 prospectus lodgement will be the first formal confirmation of the revised price and deal terms. The retail offer period running through October 19 will test whether retail can supplement demand, and then the October 23 trading debut assuming it proceeds will provide the first genuine price discovery signal from a fully open market.

For now, the Firmus IPO occupies an uncomfortable middle ground: too large and strategically significant to walk away from quietly, but too aggressively priced in its original form to clear the market without meaningful concessions.
