There's no doubt that money can be made by owning shares of unprofitable businesses. For example, although Amazon.com made losses for many years after listing, if you had bought and held the shares since 1999, you would have made a fortune. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

So, the natural question for EQRx (NASDAQ:EQRX) shareholders is whether they should be concerned by its rate of cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

You can see how its cash balance has changed over time in the image below.

How Is EQRx's Cash Burn Changing Over Time?

Because EQRx isn't currently generating revenue, we consider it an early-stage business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. As it happens, the company's cash burn reduced by 5.2% over the last year, which suggests that management are maintaining a fairly steady rate of business development, albeit with a slight decrease in spending.

How Easily Can EQRx Raise Cash?

Even though it has reduced its cash burn recently, shareholders should still consider how easy it would be for EQRx to raise more cash in the future. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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.
