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 the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.

So should Co-Diagnostics (NASDAQ:CODX) shareholders 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.

When Might Co-Diagnostics Run Out Of Money?

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 2024, Co-Diagnostics had US$45m in cash, and was debt-free. Importantly, its cash burn was US$25m over the trailing twelve months. So it had a cash runway of approximately 21 months from 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 Co-Diagnostics' Cash Burn Changing Over Time?

Although Co-Diagnostics had revenue of US$9.1m in the last twelve months, its operating revenue was only US$606k in that time period. We don't think that's enough operating revenue for us to understand too much from revenue growth rates, since the company is growing off a low base. So we'll focus on the cash burn, today. Over the last year its cash burn actually increased by a very significant 63%. While this spending increase is no doubt intended to drive growth, if the trend continues the company's cash runway will shrink very quickly. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Easily Can Co-Diagnostics Raise Cash?

Given its cash burn trajectory, Co-Diagnostics shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund 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).

Since it has a market capitalisation of US$39m, Co-Diagnostics' US$25m in cash burn equates to about 66% of its market value. That's very high expenditure relative to the company's size, suggesting it is an extremely high risk stock.

Is Co-Diagnostics' Cash Burn A Worry?
