Here's Why We're Watching Synairgen's (LON:SNG) Cash Burn Situation

We can readily understand why investors are attracted to unprofitable companies. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. But while the successes are well known, investors should not ignore the very many unprofitable companies that simply burn through all their cash and collapse.

So, the natural question for Synairgen (LON:SNG) 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. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

Does Synairgen Have A Long Cash Runway?

A cash runway is defined as the length of time it would take a company to run out of money if it kept spending at its current rate of cash burn. In December 2022, Synairgen had UK£20m in cash, and was debt-free. Importantly, its cash burn was UK£14m over the trailing twelve months. So it had a cash runway of approximately 17 months from December 2022. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. Depicted below, you can see how its cash holdings have changed over time.

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. Notably, its cash burn was actually down by 65% in the last year, which is a real positive in terms of resilience, but uninspiring when it comes to investment for growth. 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?

While we're comforted by the recent reduction evident from our analysis of Synairgen's cash burn, it is still worth considering how easily the company could raise more funds, if it wanted to accelerate spending to drive growth. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. 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£14m is about 79% of its UK£18m market capitalisation. Given how large that cash burn is, relative to the market value of the entire company, we'd consider it to be a high risk stock, with the real possibility of extreme dilution.
