There's no doubt that money can be made by owning shares of unprofitable businesses. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. But while the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.

So, the natural question for Couchbase (NASDAQ:BASE) shareholders is whether they should be concerned by its rate of cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

When Might Couchbase Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Couchbase last reported its balance sheet in July 2022, it had zero debt and cash worth US$192m. In the last year, its cash burn was US$42m. Therefore, from July 2022 it had 4.6 years of cash runway. There's no doubt that this is a reassuringly long runway. You can see how its cash balance has changed over time in the image below.

How Well Is Couchbase Growing?

Some investors might find it troubling that Couchbase is actually increasing its cash burn, which is up 6.0% in the last year. The silver lining is that revenue was up 25%, showing the business is growing at the top line. On balance, we'd say the company is improving over time. 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.

How Hard Would It Be For Couchbase To Raise More Cash For Growth?

We are certainly impressed with the progress Couchbase has made over the last year, but it is also worth considering how costly it would be if it wanted to raise more cash to fund faster growth. 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.

Couchbase's cash burn of US$42m is about 6.9% of its US$608m 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.

How Risky Is Couchbase's Cash Burn Situation?

As you can probably tell by now, we're not too worried about Couchbase's cash burn. In particular, we think its cash runway stands out as evidence that the company is well on top of its spending. Although its increasing cash burn does give us reason for pause, the other metrics we discussed in this article form a positive picture overall. Looking at all the measures in this article, together, we're not worried about its rate of cash burn; the company seems well on top of its medium-term spending needs. Separately, we looked at different risks affecting the company and spotted 3 warning signs for Couchbase (of which 1 makes us a bit uncomfortable!) you should know about.
