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

So, the natural question for SiTime (NASDAQ:SITM) 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.

How Long Is SiTime's Cash Runway?

You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. In June 2024, SiTime had US$453m in cash, and was debt-free. Looking at the last year, the company burnt through US$14m. So it had a very long cash runway of many years from June 2024. Notably, however, analysts think that SiTime will break even (at a free cash flow level) before then. If that happens, then the length of its cash runway, today, would become a moot point. Depicted below, you can see how its cash holdings have changed over time.

How Well Is SiTime Growing?

SiTime actually ramped up its cash burn by a whopping 83% in the last year, which shows it is boosting investment in the business. While that's concerning on it's own, the fact that operating revenue was actually down 23% over the same period makes us positively tremulous. Considering both these metrics, we're a little concerned about how the company is developing. 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 SiTime Raise Cash?

SiTime seems to be in a fairly good position, in terms of cash burn, but we still think it's worthwhile considering how easily it could raise more money if it wanted to. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund growth. By comparing a company's annual cash burn to its total market capitalisation, we can estimate roughly how many shares it would have to issue in order to run the company for another year (at the same burn rate).

Since it has a market capitalisation of US$3.2b, SiTime's US$14m in cash burn equates to about 0.4% of its market value. So it could almost certainly just borrow a little to fund another year's growth, or else easily raise the cash by issuing a few shares.

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

As you can probably tell by now, we're not too worried about SiTime's cash burn. In particular, we think its cash runway stands out as evidence that the company is well on top of its spending. While we must concede that its increasing cash burn is a bit worrying, the other factors mentioned in this article provide great comfort when it comes to the cash burn. There's no doubt that shareholders can take a lot of heart from the fact that analysts are forecasting it will reach breakeven before too long. After considering a range of factors in this article, we're pretty relaxed about its cash burn, since the company seems to be in a good position to continue to fund its growth. An in-depth examination of risks revealed 3 warning signs for SiTime that readers should think about before committing capital to this stock.
