We can readily understand why investors are attracted to unprofitable companies. 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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

So should Sequans Communications (NYSE:SQNS) shareholders be worried about its cash burn? In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

Does Sequans Communications Have A Long 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 2026, Sequans Communications had US$21m in cash, and was debt-free. Looking at the last year, the company burnt through US$41m. That means it had a cash runway of around 6 months as of June 2026. To be frank, this kind of short runway puts us on edge, as it indicates the company must reduce its cash burn significantly, or else raise cash imminently. You can see how its cash balance has changed over time in the image below.

How Well Is Sequans Communications Growing?

On balance, we think it's mildly positive that Sequans Communications trimmed its cash burn by 10% over the last twelve months. Unfortunately, however, operating revenue declined by 37% during the period. Considering both these metrics, we're a little concerned about how the company is developing. 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 Hard Would It Be For Sequans Communications To Raise More Cash For Growth?

Since Sequans Communications revenue has been falling, the market will likely be considering how it can raise more cash if need be. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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).

Sequans Communications' cash burn of US$41m is about 89% of its US$46m market capitalisation. That suggests the company may have some funding difficulties, and we'd be very wary of the stock.

So, Should We Worry About Sequans Communications' Cash Burn?

As you can probably tell by now, we're rather concerned about Sequans Communications' cash burn. Take, for example, its cash burn relative to its market cap, which suggests the company may have difficulty funding itself, in the future. While not as bad as its cash burn relative to its market cap, its cash burn reduction is also a concern, and considering everything mentioned above, we're struggling to find much to be optimistic about. After considering the data discussed in this article, we don't have a lot of confidence that its cash burn rate is prudent, as it seems like it might need more cash soon. On another note, Sequans Communications has 2 warning signs (and 1 which shouldn't be ignored) we think you should know about.
