What does the future hold for 4DMedical (ASX:4DX) Investors?

4DX Medical’s Future: What Investors Should Watch

We have been closely following 4DMedical since 25c per share and have published extensive analysis on the company over time. Today’s announcement saw the stock surge 18% following the appointment of a new Chief Financial Officer, Julian Sutton, who has been a non-executive director and an early shareholder since 2017.

In our discussions with retail investors, it has become clear that many individuals hold highly concentrated positions in 4DMedical, which is why we think it is important to step back and help investors assess what the future may look like from both a risk and reward perspective.

It is also worth grounding expectations. Share price performance like that seen in 4DMedical is not a normal market outcome.

Another ASX unicorn

Delivering a return of around 1,700% in just six months is extremely rare and often involves a degree of timing and luck alongside strong fundamentals. We believe that when a single stock becomes overconcentrated within a portfolio, particularly above the 10% to 20% range, it is sensible for investors to reassess their exposure.

Taking the time to review position sizing and consider redistributing gains across other opportunities can be a prudent step in managing risk, regardless of how compelling the long term story may appear.

With that context in mind, we think it is important to clearly outline both the bull and bear cases. Our aim is to help investors understand why the company could continue to perform strongly, as well as the key risks and catalysts that could negatively impact the share price.

The bull case for 4DX

Starting with the bull case, we have already seen encouraging early commercial traction. Partnerships with global imaging leaders such as Philips, alongside adoption by leading institutions including Cleveland Clinic, Stanford University, and the University of Miami, support the credibility and clinical relevance of 4DMedical’s technology.

A key question for any small-cap healthcare company is scalability, and this is where we see a compelling opportunity. The CT ventilation scan integrates into existing imaging hardware, which significantly lowers barriers to adoption and enables a scalable software-led revenue model.

This is driven by reimbursement and distribution, rather than the need for clinics to invest in new hardware. In our view, this is fundamentally a software-on-installed-base story, not a traditional hardware rollout.

Looking ahead, if partners such as Philips, which already has a committed pipeline value of around A$10 million, can continue to support distribution, this could materially accelerate integration across new hospital networks.

This opportunity is further strengthened by the company’s progress on reimbursement. Management has communicated that Centers for Medicare and Medicaid Services reimbursement codes are in place for its key products, including scan-level reimbursement.

This is a critical catalyst, as it converts clinical value into a repeatable and economically attractive workflow for clinics, increasing the likelihood of ongoing usage and supporting long-term revenue scalability.

Upside valuation for 4DX

If we continue to see strong execution from distribution partners, the upside case becomes clearer. Successful rollout through existing partners would not only attract new commercial relationships but also act as a powerful momentum signal to the market.

As scan adoption increases, revenues should scale more quickly, while cash flow visibility improves as recurring usage builds. From our perspective, consistent execution at the distribution level is one of the most important drivers of confidence in the long-term story.

In a constructive bull case scenario, this execution could translate into further share price upside. On the back of a successful Philips rollout, alongside expansion across US government channels, the business could move closer to profitability.

Under these conditions, we see a pathway where the stock could justify a valuation in the range of A$5 to A$6 per share or higher, implying a market capitalisation above A$2.5 billion, assuming sustained execution and accelerating commercial momentum.

How is the market pricing 4D Medical today?

At the current share price of around A$4.50, 4DMedical is being valued on a very optimistic outlook. In FY25, the company reported revenue of A$5.8 million, up from A$3.7 million the prior year. While that growth is encouraging, the business is still consuming cash at a meaningful rate, with a full year loss of approximately A$30 million.

At a market capitalisation of roughly A$2 billion, the stock is effectively priced as if strong revenue acceleration and a clear path to profitability are already locked in.

That leaves little margin for execution risk. If growth slows, adoption takes longer than expected, or costs remain elevated, the valuation could quickly come under pressure. In that scenario, investors should be prepared for potential drawdowns in the order of 20% to 40%. This is a stock where expectations are high, and delivery needs to remain consistently strong.

Commercial risks

Turning to the downside risks, there are several catalysts investors should be mindful of that could weigh on the share price if they materialise.

A key risk is slower than expected adoption at the hospital and clinical level. If scan volumes ramp more gradually, this would delay revenue build and reduce near-term forecasting confidence.

Distribution execution also matters. The business currently has a high reliance on Philips for US distribution, and if sales targets are missed or momentum slows, access to the market could be more limited than investors currently expect.

Financial risks

From a financial perspective, the company is still operating at a loss, which means ongoing growth is required to fund operations.

If commercial traction does not accelerate as planned, there is a risk that additional capital may be required, introducing potential dilution.

Investors should also remain aware of balance sheet sensitivities. Past scrutiny around intangible asset valuations following acquisitions such as Imbio highlights that write downs or reassessments could impact market confidence if expectations are not met.

Clinical adoption risks

Looking at clinical adoption more broadly, partnerships with leading institutions such as Stanford University provide strong validation, but the market will ultimately demand clear evidence that these scans change physician behaviour at scale.

Validation studies and clinical advocacy are important, but widespread uptake depends on referral patterns shifting and clinicians choosing these scans over competing modalities.

If ordering behaviour does not meaningfully change, or alternative imaging approaches remain preferred, adoption could fall short of bullish expectations. For investors, these are the key areas to watch closely as the story continues to unfold.
