There's no doubt that money can be made by owning shares of unprofitable businesses. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. 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 SiTime (NASDAQ:SITM) shareholders should be worried about its 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. Let's start with an examination of the business' cash, relative to its cash burn.

How Long Is SiTime's Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at September 2024, SiTime had cash of US$435m and no debt. Looking at the last year, the company burnt through US$15m. So it had a very long cash runway of many years from September 2024. Notably, however, analysts think that SiTime will break even (at a free cash flow level) before then. In that case, it may never reach the end of its cash runway. The image below shows how its cash balance has been changing over the last few years.

How Well Is SiTime Growing?

One thing for shareholders to keep front in mind is that SiTime increased its cash burn by 505% in the last twelve months. While operating revenue was up over the same period, the 9.0% gain gives us scant comfort. In light of the above-mentioned, we're pretty wary of the trajectory the company seems to be on. 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 Hard Would It Be For SiTime To Raise More Cash For Growth?

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. 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.

SiTime has a market capitalisation of US$5.0b and burnt through US$15m last year, which is 0.3% of the company's 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.

Is SiTime's Cash Burn A Worry?

It may already be apparent to you that we're relatively comfortable with the way SiTime is burning through its cash. For example, we think its cash runway suggests that the company is on a good path. Although we do find its increasing cash burn to be a bit of a negative, once we consider the other metrics mentioned in this article together, the overall picture is one we are comfortable with. 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.
