We can readily understand why investors are attracted to unprofitable companies. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

Given this risk, we thought we'd take a look at whether Enliven Therapeutics (NASDAQ:ELVN) shareholders should be worried about its cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

When Might Enliven 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. As at September 2024, Enliven Therapeutics had cash of US$292m and no debt. Looking at the last year, the company burnt through US$69m. That means it had a cash runway of about 4.3 years as of September 2024. There's no doubt that this is a reassuringly long runway. The image below shows how its cash balance has been changing over the last few years.

How Is Enliven Therapeutics' Cash Burn Changing Over Time?

Enliven Therapeutics didn't record any revenue over the last year, indicating that it's an early stage company still developing its 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. With the cash burn rate up 20% in the last year, it seems that the company is ratcheting up investment in the business over time. 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. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Easily Can Enliven Therapeutics Raise Cash?

Given its cash burn trajectory, Enliven Therapeutics shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. 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$1.1b, Enliven Therapeutics' US$69m in cash burn equates to about 6.1% of its market value. 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.

Is Enliven Therapeutics' Cash Burn A Worry?

It may already be apparent to you that we're relatively comfortable with the way Enliven Therapeutics is burning through its cash. For example, we think its cash runway suggests that the company is on a good path. 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.
