We're A Little Worried About Synairgen's (LON:SNG) Cash Burn Rate

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 Synairgen (LON:SNG) shareholders is whether they should be concerned by its rate of cash burn. For the purpose of this article, we'll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow). The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

Does Synairgen Have A Long Cash Runway?

A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. When Synairgen last reported its balance sheet in December 2021, it had zero debt and cash worth UK£34m. In the last year, its cash burn was UK£41m. So it had a cash runway of approximately 10 months from December 2021. 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 Is Synairgen's Cash Burn Changing Over Time?

Because Synairgen isn't currently generating revenue, we consider it an early-stage business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. Over the last year its cash burn actually increased by a very significant 72%. While this spending increase is no doubt intended to drive growth, if the trend continues the company's cash runway will shrink very quickly. While the past is always worth studying, it is the future that matters most of all. 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 Synairgen Raise Cash?

Since its cash burn is moving in the wrong direction, Synairgen shareholders may wish to think ahead to when the company may need to raise more cash. 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.

Synairgen's cash burn of UK£41m is about the same as its market capitalisation of UK£41m. That suggests the company may have some funding difficulties, and we'd be very wary of the stock.

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

As you can probably tell by now, we're rather concerned about Synairgen's cash burn. In particular, we think its cash burn relative to its market cap suggests it isn't in a good position to keep funding growth. And although we accept its cash runway wasn't as worrying as its cash burn relative to its market cap, it was still a real negative; as indeed were all the factors we considered in this article. 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. Taking a deeper dive, we've spotted 6 warning signs for Synairgen you should be aware of, and 4 of them can't be ignored.
