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 while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

So, the natural question for Sage Therapeutics (NASDAQ:SAGE) shareholders is whether they should be concerned by its rate of 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. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

When Might Sage Therapeutics Run Out Of Money?

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. In March 2024, Sage Therapeutics had US$717m in cash, and was debt-free. In the last year, its cash burn was US$425m. Therefore, from March 2024 it had roughly 20 months of cash runway. Notably, analysts forecast that Sage Therapeutics will break even (at a free cash flow level) in about 4 years. That means unless the company reduces its cash burn quickly, it may well look to raise more cash. The image below shows how its cash balance has been changing over the last few years.

How Well Is Sage Therapeutics Growing?

Sage Therapeutics reduced its cash burn by 16% during the last year, which points to some degree of discipline. But this achievement is overshadowed by the brilliant operating revenue growth of 869%. We think it is growing rather well, upon reflection. 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 Sage Therapeutics Raise Cash?

Sage Therapeutics seems to be in a fairly good position, in terms of cash burn, but we still think it's worthwhile considering how easily it could raise more money if it wanted to. 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.

Sage Therapeutics has a market capitalisation of US$642m and burnt through US$425m last year, which is 66% of the company's market value. Given how large that cash burn is, relative to the market value of the entire company, we'd consider it to be a high risk stock, with the real possibility of extreme dilution.

How Risky Is Sage Therapeutics' Cash Burn Situation?

On this analysis of Sage Therapeutics' cash burn, we think its revenue growth was reassuring, while its cash burn relative to its market cap has us a bit worried. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. 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. Its important for readers to be cognizant of the risks that can affect the company's operations, and we've picked out 2 warning signs for Sage Therapeutics that investors should know when investing in the stock.
