We can readily understand why investors are attracted to unprofitable companies. For example, although Amazon.com made losses for many years after listing, if you had bought and held the shares since 1999, you would have made a fortune. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.
Given this risk, we thought we'd take a look at whether Pharmx Technologies (ASX:PHX) shareholders should be worried about its cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.
You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. In June 2026, Pharmx Technologies had AU$2.6m in cash, and was debt-free. In the last year, its cash burn was AU$1.3m. So it had a cash runway of about 2.0 years from June 2026. That's decent, giving the company a couple years to develop its business. You can see how its cash balance has changed over time in the image below.

Pharmx Technologies managed to reduce its cash burn by 87% over the last twelve months, which is extremely promising, when it comes to considering its need for cash. And while hardly exciting, it was still good to see revenue growth of 4.1% during that time. It seems to be growing nicely. In reality, this article only makes a short study of the company's growth data. This graph of historic earnings and revenue shows how Pharmx Technologies is building its business over time.
While Pharmx Technologies seems to be in a decent position, we reckon it is still worth thinking about how easily it could raise more cash, if that proved desirable. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund growth. We can compare a company's cash burn to its market capitalisation to get a sense for how many new shares a company would have to issue to fund one year's operations.
Pharmx Technologies has a market capitalisation of AU$62m and burnt through AU$1.3m last year, which is 2.1% of the company's market value. That means it could easily issue a few shares to fund more growth, and might well be in a position to borrow cheaply.
As you can probably tell by now, we're not too worried about Pharmx Technologies' cash burn. For example, we think its cash burn reduction suggests that the company is on a good path. Its weak point is its revenue growth, but even that wasn't too bad! Looking at all the measures in this article, together, we're not worried about its rate of cash burn, which seems to be under control. On another note, Pharmx Technologies has 2 warning signs (and 1 which is a bit unpleasant) we think you should know about.
