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, 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.

So, the natural question for Beta Bionics (NASDAQ:BBNX) shareholders is whether they should be concerned by its rate of cash burn. For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

Does Beta Bionics Have A Long Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Beta Bionics last reported its September 2025 balance sheet in October 2025, it had zero debt and cash worth US$229m. In the last year, its cash burn was US$61m. That means it had a cash runway of about 3.8 years as of September 2025. Importantly, analysts think that Beta Bionics will reach cashflow breakeven in 5 years. That means unless the company reduces its cash burn quickly, it may well look to raise more cash. The image below shows how its cash balance has been changing over the last few years.

How Well Is Beta Bionics Growing?

Some investors might find it troubling that Beta Bionics is actually increasing its cash burn, which is up 39% in the last year. But looking on the bright side, its revenue gained by 67%, lending some credence to the growth narrative. Of course, with spend going up shareholders will want to see fast growth continue. It seems to be growing nicely. 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 Beta Bionics Raise Cash?

There's no doubt Beta Bionics seems to be in a fairly good position, when it comes to managing its cash burn, but even if it's only hypothetical, it's always worth asking how easily it could raise more money to fund growth. 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.

Beta Bionics has a market capitalisation of US$1.4b and burnt through US$61m last year, which is 4.3% of the company's 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.

So, Should We Worry About Beta Bionics' Cash Burn?

As you can probably tell by now, we're not too worried about Beta Bionics' cash burn. For example, we think its revenue growth 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. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. 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.
