Just because a business does not make any money, does not mean that the stock will go down. 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?

So, the natural question for Medical Developments International (ASX:MVP) shareholders is whether they should be concerned by its rate of cash burn. For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

How Long Is Medical Developments International's 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. When Medical Developments International last reported its June 2023 balance sheet in August 2023, it had zero debt and cash worth AU$25m. In the last year, its cash burn was AU$25m. So it had a cash runway of approximately 12 months from June 2023. That's quite a short cash runway, indicating the company must either reduce its annual cash burn or replenish its cash. Depicted below, you can see how its cash holdings have changed over time.

How Well Is Medical Developments International Growing?

Medical Developments International boosted investment sharply in the last year, with cash burn ramping by 55%. On the bright side, at least operating revenue was up 47% over the same period, giving some cause for hope. Considering the factors above, the company doesn’t fare badly when it comes to assessing how it is changing over time. While the past is always worth studying, it is the future that matters most of all. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Easily Can Medical Developments International Raise Cash?

While Medical Developments International seems to be in a fairly good position, it's still worth considering how easily it could raise more cash, even just to fuel faster growth. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. Commonly, a business will sell new shares in itself to raise cash and drive 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).

Medical Developments International's cash burn of AU$25m is about 29% of its AU$85m market capitalisation. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.

So, Should We Worry About Medical Developments International's Cash Burn?
