Even when a business is losing money, it's possible for shareholders to make money if they buy a good business at the right price. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

Given this risk, we thought we'd take a look at whether Disc Medicine (NASDAQ:IRON) shareholders should 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.

How Long Is Disc Medicine's Cash Runway?

You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. When Disc Medicine last reported its June 2024 balance sheet in August 2024, it had zero debt and cash worth US$501m. Importantly, its cash burn was US$74m over the trailing twelve months. Therefore, from June 2024 it had 6.7 years of cash runway. While this is only one measure of its cash burn situation, it certainly gives us the impression that holders have nothing to worry about. The image below shows how its cash balance has been changing over the last few years.

How Is Disc Medicine's Cash Burn Changing Over Time?

Because Disc Medicine 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. With the cash burn rate up 10.0% 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. 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 Disc Medicine To Raise More Cash For Growth?

While its cash burn is only increasing slightly, Disc Medicine shareholders should still consider the potential need for further cash, down the track. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. 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.

Since it has a market capitalisation of US$1.3b, Disc Medicine's US$74m in cash burn equates to about 5.8% 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.

How Risky Is Disc Medicine's Cash Burn Situation?

It may already be apparent to you that we're relatively comfortable with the way Disc Medicine 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. After taking into account the various metrics mentioned in this report, we're pretty comfortable with how the company is spending its cash, as it seems on track to meet its needs over the medium term. On another note, Disc Medicine has 4 warning signs (and 2 which are a bit concerning) we think you should know about.
