There's no doubt that money can be made by owning shares of unprofitable businesses. 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. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

Given this risk, we thought we'd take a look at whether Day One Biopharmaceuticals (NASDAQ:DAWN) shareholders should be worried about its 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). The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

When Might Day One Biopharmaceuticals 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 December 2022, Day One Biopharmaceuticals had US$342m in cash, and was debt-free. Looking at the last year, the company burnt through US$110m. So it had a cash runway of about 3.1 years from December 2022. Importantly, analysts think that Day One Biopharmaceuticals will reach cashflow breakeven in 4 years. That means unless the company reduces its cash burn quickly, it may well look to raise more cash. You can see how its cash balance has changed over time in the image below.

How Is Day One Biopharmaceuticals' Cash Burn Changing Over Time?

Because Day One Biopharmaceuticals 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. Over the last year its cash burn actually increased by a very significant 94%. Oftentimes, increased cash burn simply means a company is accelerating its business development, but one should always be mindful that this causes the cash runway to shrink. 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.

Can Day One Biopharmaceuticals Raise More Cash Easily?

Given its cash burn trajectory, Day One Biopharmaceuticals shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Companies can raise capital through either debt or equity. 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.

Day One Biopharmaceuticals' cash burn of US$110m is about 7.6% of its US$1.5b market capitalisation. That's a low proportion, so we figure the company would be able to raise more cash to fund growth, with a little dilution, or even to simply borrow some money.
