An IPO must stack up: what the Firmus withdrawal tells us about selling a business to the public

An initial public offering can turn a private business into a household investment name. It can finance expansion, reward early backers and give ordinary investors a share in an enterprise they could previously only watch from a distance.

But the journey from ambitious business to listed company involves a hard negotiation: what are investors being asked to pay, and what evidence supports that price?

Firmus Technologies brought that question into focus on 9 October when it withdrew its application to list on the Australian Securities Exchange. The artificial intelligence infrastructure company said market volatility and prevailing conditions meant the offer could not proceed on terms that appropriately reflected its business and growth outlook. It will pursue private capital and consider other market options.

The withdrawal provides a useful window into how IPOs work—and why even a business operating in an exciting industry can struggle to attract buyers.

What is an IPO?

IPO stands for initial public offering. Often called a float, it is the process through which a company first offers shares to the public. Once admitted to an exchange such as the ASX, its shares can be bought and sold between investors.

Buying a share means acquiring a small ownership interest. It does not guarantee a dividend, a capital gain or recovery of the money invested.

There is also an important distinction between money raised for the business and money paid to existing owners.

An offer can involve newly issued shares, with proceeds going to the company, or existing shares being sold by shareholders. It can combine both. Investors should understand how much supports expansion, repays debt, covers transaction costs or allows owners to cash out.

A large float is not necessarily a large injection of growth capital.

How a float is born

The starting point is usually a commercial decision. A business needs money to expand, acquire another company or restructure its finances. Alternatively, founders or early investors want a market for their holdings.

Management and the board assess whether public ownership suits the business. Listing brings access to capital, but also disclosure obligations, scrutiny and costs.

Advisers help prepare the company, examine its finances and develop the offer. Lawyers, accountants, investment banks, brokers and a share registry have roles in preparing and administering the transaction.

For a conventional public share offer, the prospectus is the central disclosure document. It explains the company, its financial position, the securities being offered and associated risks.

Potential institutional investors are approached to test demand. In a bookbuild, bids help establish whether investors will support the offer at its proposed price and size. The response can lead to revisions—or withdrawal.

The company also works through ASIC disclosure requirements and ASX admission procedures. Completing those processes does not make an investment certain to succeed. ASIC expressly says it does not endorse offers appearing on its offer notice board.

Who gets involved—and what do they want?

A float brings together parties with different responsibilities and incentives.

Founders may want expansion capital while retaining control. Early investors may want an opportunity to realise gains. Management must deliver the business plan. Advisers help bring the transaction to market.

Institutional investors—including investment funds and superannuation funds—assess the offer against other opportunities. Participating retail investors must decide whether the investment suits their circumstances.

These interests can align, but investors should examine where they differ.

How much money stays in the business? How much ownership does management retain? When can existing shareholders sell? What further funding might be required?

The presence of experienced advisers or prominent backers can be relevant. Buyers still need to examine precisely what they are purchasing.

What happened to Firmus?

Firmus designs and operates infrastructure supplying computing capacity for artificial intelligence. Its founders and co-chief executives include Oliver Curtis and Tim Rosenfield. Reuters identified Nvidia, Coatue, Blackstone and Jane Street among its backers, and Bank of America, JPMorgan, Morgan Stanley and Morgans as leaders of the IPO bookbuild.

Its proposition was substantial: expand AI infrastructure across the Asia-Pacific region.

The ABC reported a proposed equity valuation of approximately A$44 billion and an offer price of A$11 a share. It also reported two operating sites and five under development.

Those distinctions matter. An operating facility can demonstrate performance. A planned facility depends on construction, financing, equipment, electricity, customers and successful commissioning.

According to Reuters, investors became concerned about expansion execution, the departure of development partner CDC from a major planned rollout, and arrangements that would have allowed more than half the stock to be sold by existing investors from the first day of trading.

Being permitted to sell does not mean every eligible holder would have sold. Nevertheless, the potential supply of stock was relevant to prospective buyers.

UniSuper chief investment officer John Pearce identified valuation and the possibility of further debt and equity funding as concerns, the ABC reported.

Firmus’s explanation and investors’ concerns should both be understood. The company judged the available terms inadequate. Potential buyers questioned the proposition at the proposed price.

Financial climate—or a particular company?

Every IPO operates within a financial climate.

In general, higher interest rates increase financing costs and give investors alternatives to shares. They also reduce the present value investors assign to earnings expected far into the future. Uncertainty can make buyers demand a larger margin for error.

But market conditions alone cannot explain every unsuccessful float.

For a company planning expensive infrastructure, investors must examine the distance between today’s operations and tomorrow’s earnings.

How much remains to be built? Is the funding secured? What happens if construction is late, costs rise or customer demand changes?

These are questions about the particular business and product, as well as the economy.

The editorial lesson from Firmus is that enthusiasm for AI infrastructure does not automatically establish the value of an individual supplier. A growing market can still contain offers that investors consider too expensive.

A useful technology, a credible business and an attractive investment are three separate assessments.

What does it mean for the ASX?

The withdrawal disappointed investors hoping for a major addition to Australia’s listed technology sector.

Reuters reported that the ASX had 1,891 listed companies in September 2026, compared with 2,066 in 2016. Its market remains heavily concentrated in major banks and mining companies. Fund managers described the lost float as a setback for investment choice and market diversity.

That is a real concern. A healthy public market should offer access to businesses across different industries and stages of development.

However, attracting listings and accepting valuations are separate matters.

An IPO withdrawal does not, by itself, establish that the wider share market is collapsing or that the company cannot succeed. It establishes that this proposed transaction did not proceed.

Our assessment is that investors’ willingness to withhold support is also part of a functioning market. Public capital has to be earned on acceptable terms.

Lessons for businesses

The lessons extend beyond companies considering a float.

Separate achievement from ambition. Explain what operates today, what is contracted and what remains conditional.

Show the whole funding requirement. The first capital raising may be only one stage. Further equity can dilute existing shareholders, while additional borrowing creates repayment obligations.

Explain the route from sales to cash. Revenue forecasts are more useful when accompanied by the costs, capital spending and financing needed to deliver them.

Make incentives visible. Investors need to understand who receives the proceeds, who retains ownership and when existing holders can sell.

Allow for setbacks. A business case becomes more persuasive when it explains how the company would cope with delays and weaker outcomes.

For owners seeking any form of finance, credibility comes from making the proposition understandable and testable.

The Times View

Australia needs businesses willing to build, innovate and take commercial risks. Public markets can help finance that work and allow Australians to share in its rewards.

An IPO nevertheless has to stack up.

Investors deserve real information about operating performance, contracts, debt, funding needs, management and the assumptions behind forecasts. They should be able to distinguish what exists from what must still be achieved.

The withdrawal of Firmus’s float is not a final verdict on its technology or future. It is a reminder that a company’s confidence in its prospects and investors’ willingness to pay for them are different things.

A prospectus should make the future open to examination. It should leave room for uncertainty rather than asking buyers to inhabit a financial fairyland where everything goes right.

Ambition describes what a business hopes to become. Evidence allows investors to decide what that hope is worth.
