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?

Given this risk, we thought we'd take a look at whether 4DS Memory (ASX:4DS) shareholders should be worried about its 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. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

Does 4DS Memory Have A Long Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at June 2024, 4DS Memory had cash of AU$7.9m and no debt. Importantly, its cash burn was AU$4.7m over the trailing twelve months. That means it had a cash runway of around 20 months as of June 2024. 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 4DS Memory's Cash Burn Changing Over Time?

While 4DS Memory did record statutory revenue of AU$8.1k over the last year, it didn't have any revenue from operations. To us, that makes it a pre-revenue company, so we'll look to its cash burn trajectory as an assessment of its cash burn situation. Cash burn was pretty flat over the last year, which suggests that management are holding spending steady while the business advances its strategy. Clearly, however, the crucial factor is whether the company will grow its business going forward. So you might want to take a peek at how much the company is expected to grow in the next few years.

Can 4DS Memory Raise More Cash Easily?

While its cash burn is only increasing slightly, 4DS Memory shareholders should still consider the potential need for further cash, down the track. 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. 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).

4DS Memory's cash burn of AU$4.7m is about 3.1% of its AU$152m market capitalisation. 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.

Is 4DS Memory's Cash Burn A Worry?

On this analysis of 4DS Memory's cash burn, we think its cash burn relative to its market cap was reassuring, while its increasing cash burn has us a bit worried.
