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 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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

So, the natural question for Invivyd (NASDAQ:IVVD) shareholders is whether they should be concerned by its rate of 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. Let's start with an examination of the business' cash, relative to its cash burn.

How Long Is Invivyd's Cash Runway?

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. In March 2026, Invivyd had US$184m in cash, and was debt-free. Importantly, its cash burn was US$79m over the trailing twelve months. So it had a cash runway of about 2.3 years from March 2026. Importantly, analysts think that Invivyd will reach cashflow breakeven in 3 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 Invivyd Growing?

It was fairly positive to see that Invivyd reduced its cash burn by 44% during the last year. And arguably the operating revenue growth of 52% was even more impressive. It seems to be growing nicely. 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 Easily Can Invivyd Raise Cash?

We are certainly impressed with the progress Invivyd has made over the last year, but it is also worth considering how costly it would be if it wanted to raise more cash to fund faster growth. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. Commonly, a business will sell new shares in itself to raise cash and drive 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.

Since it has a market capitalisation of US$245m, Invivyd's US$79m in cash burn equates to about 32% of its market value. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.

So, Should We Worry About Invivyd's Cash Burn?

Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought Invivyd's revenue growth was relatively promising. One real positive is that analysts are forecasting that the company will reach breakeven. Considering all the factors discussed in this article, we're not overly concerned about the company's cash burn, although we do think shareholders should keep an eye on how it develops.
