Just because a business does not make any money, does not mean that the stock will go down. 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 Silicon Laboratories (NASDAQ:SLAB) 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. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

When Might Silicon Laboratories Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at December 2024, Silicon Laboratories had cash of US$382m and no debt. Importantly, its cash burn was US$26m over the trailing twelve months. So it had a very long cash runway of many years from December 2024. Notably, however, analysts think that Silicon Laboratories 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 Silicon Laboratories Growing?

We reckon the fact that Silicon Laboratories managed to shrink its cash burn by 51% over the last year is rather encouraging. Unfortunately, however, operating revenue declined by 25% during the period. On balance, we'd say the company is improving over time. 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 Silicon Laboratories Raise Cash?

We are certainly impressed with the progress Silicon Laboratories 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. 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 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.

Silicon Laboratories' cash burn of US$26m is about 0.6% of its US$4.4b market capitalisation. 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 Silicon Laboratories' Cash Burn A Worry?

It may already be apparent to you that we're relatively comfortable with the way Silicon Laboratories is burning through its cash. For example, we think its cash runway suggests that the company is on a good path. While its falling revenue wasn't great, the other factors mentioned in this article more than make up for weakness on that measure. It's clearly very positive to see that analysts are forecasting the company will break even fairly soon. 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.
