Just because a business does not make any money, does not mean that the stock will go down. 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. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

So should Cogent Biosciences (NASDAQ:COGT) shareholders be worried about its 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.

When Might Cogent Biosciences 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. As at September 2024, Cogent Biosciences had cash of US$336m and no debt. In the last year, its cash burn was US$192m. So it had a cash runway of approximately 21 months from September 2024. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. The image below shows how its cash balance has been changing over the last few years.

How Is Cogent Biosciences' Cash Burn Changing Over Time?

Because Cogent Biosciences isn't currently generating revenue, we consider it an early-stage business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. Over the last year its cash burn actually increased by 34%, which suggests that management are increasing investment in future growth, but not too quickly. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. While the past is always worth studying, it is the future that matters most of all. 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 Cogent Biosciences To Raise More Cash For Growth?

While Cogent Biosciences does have a solid cash runway, its cash burn trajectory may have some shareholders thinking ahead to when the company may need to raise more cash. 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 looking at a company's cash burn relative to its market capitalisation, we gain insight on how much shareholders would be diluted if the company needed to raise enough cash to cover another year's cash burn.

Cogent Biosciences has a market capitalisation of US$905m and burnt through US$192m last year, which is 21% of the company's market value. That's fairly notable cash burn, so if the company had to sell shares to cover the cost of another year's operations, shareholders would suffer some costly dilution.

How Risky Is Cogent Biosciences' Cash Burn Situation?

On this analysis of Cogent Biosciences' cash burn, we think its cash runway was reassuring, while its increasing cash burn has us a bit worried. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future.
