There's no doubt that money can be made by owning shares of unprofitable businesses. 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. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?
Given this risk, we thought we'd take a look at whether TMK Energy (ASX:TMK) shareholders should be worried about its cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.
A cash runway is defined as the length of time it would take a company to run out of money if it kept spending at its current rate of cash burn. In June 2026, TMK Energy had AU$5.4m in cash, and was debt-free. In the last year, its cash burn was AU$5.1m. Therefore, from June 2026 it had roughly 13 months of cash runway. 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.

Because TMK Energy isn't currently generating revenue, we consider it an early-stage business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. Even though it doesn't get us excited, the 35% reduction in cash burn year on year does suggest the company can continue operating for quite some time. Admittedly, we're a bit cautious of TMK Energy due to its lack of significant operating revenues. We prefer most of the stocks on this list of stocks that analysts expect to grow.
While TMK Energy is showing a solid reduction in its cash burn, it's still worth considering how easily it could raise more cash, even just to fuel faster growth. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Commonly, a business will sell new shares in itself to raise cash and drive 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.
TMK Energy's cash burn of AU$5.1m is about 13% of its AU$38m market capitalisation. Given that situation, it's fair to say the company wouldn't have much trouble raising more cash for growth, but shareholders would be somewhat diluted.
TMK Energy appears to be in pretty good health when it comes to its cash burn situation. One the one hand we have its solid cash burn relative to its market cap, while on the other it can also boast very strong cash burn reduction. We don't think its cash burn is particularly problematic, but after considering the range of factors in this article, we do think shareholders should be monitoring how it changes over time. On another note, TMK Energy has 4 warning signs (and 3 which are potentially serious) we think you should know about.
