Companies Like Estrella Resources (ASX:ESR) Are In A Position To Invest In Growth

There's no doubt that money can be made by owning shares of unprofitable businesses. For example, although software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

So, the natural question for Estrella Resources (ASX:ESR) shareholders is whether they should be concerned by its rate of cash burn. In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

How Long Is Estrella Resources' 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. When Estrella Resources last reported its June 2025 balance sheet in September 2025, it had zero debt and cash worth AU$6.6m. Importantly, its cash burn was AU$4.0m over the trailing twelve months. That means it had a cash runway of around 20 months as of June 2025. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. The image below shows how its cash balance has been changing over the last few years.

How Is Estrella Resources' Cash Burn Changing Over Time?

Although Estrella Resources reported revenue of AU$36k last year, it didn't actually have any revenue from operations. That means we consider it a pre-revenue business, and we will focus our growth analysis on cash burn, for now. Over the last year its cash burn actually increased by 44%, which suggests that management are increasing investment in future growth, but not too quickly. That's not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway. Estrella Resources makes us a little nervous due to its lack of substantial operating revenue. So we'd generally prefer stocks from this list of stocks that have analysts forecasting growth.

How Easily Can Estrella Resources Raise Cash?

Given its cash burn trajectory, Estrella Resources shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund growth. By comparing a company's annual cash burn to its total market capitalisation, we can estimate roughly how many shares it would have to issue in order to run the company for another year (at the same burn rate).

Estrella Resources has a market capitalisation of AU$73m and burnt through AU$4.0m last year, which is 5.5% of the company's market value. Given that is a rather small percentage, it would probably be really easy for the company to fund another year's growth by issuing some new shares to investors, or even by taking out a loan.
