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

Given this risk, we thought we'd take a look at whether CARGO Therapeutics (NASDAQ:CRGX) 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'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

When Might CARGO Therapeutics 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. When CARGO Therapeutics last reported its June 2024 balance sheet in August 2024, it had zero debt and cash worth US$443m. Looking at the last year, the company burnt through US$128m. That means it had a cash runway of about 3.5 years as of June 2024. A runway of this length affords the company the time and space it needs to develop the business. Depicted below, you can see how its cash holdings have changed over time.

How Is CARGO Therapeutics' Cash Burn Changing Over Time?

Because CARGO Therapeutics 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. In fact, it ramped its spending strongly over the last year, increasing cash burn by 142%. It's fair to say that sort of rate of increase cannot be maintained for very long, without putting pressure on the balance sheet. Clearly, however, the crucial factor is whether the company will grow its business going forward. 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 CARGO Therapeutics To Raise More Cash For Growth?

While CARGO Therapeutics 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. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. Many companies end up issuing new shares to fund future 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.
