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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

So, the natural question for 4DS Memory (ASX:4DS) 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. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

How Long Is 4DS Memory's Cash Runway?

A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. As at December 2022, 4DS Memory had cash of AU$3.4m and no debt. In the last year, its cash burn was AU$4.9m. Therefore, from December 2022 it had roughly 8 months of cash runway. To be frank, this kind of short runway puts us on edge, as it indicates the company must reduce its cash burn significantly, or else raise cash imminently.

How Is 4DS Memory's Cash Burn Changing Over Time?

While 4DS Memory did record statutory revenue of AU$1.0 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. Admittedly, we're a bit cautious of 4DS Memory due to its lack of significant operating revenues. So we'd generally prefer stocks from this list of stocks that have analysts forecasting growth.

Can 4DS Memory Raise More Cash Easily?

Since its cash burn is increasing (albeit only slightly), 4DS Memory shareholders should still be mindful of the possibility it will require more cash in the future. Companies can raise capital through either debt or equity. 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.

4DS Memory has a market capitalisation of AU$44m and burnt through AU$4.9m last year, which is 11% of the company's market value. 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.

Even though its cash runway makes us a little nervous, we are compelled to mention that we thought 4DS Memory's cash burn relative to its market cap was relatively promising.
