Here's Why We're Watching ESS Tech's (NYSE:GWH) Cash Burn Situation

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. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

Given this risk, we thought we'd take a look at whether ESS Tech (NYSE:GWH) shareholders should 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'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

How Long Is ESS Tech's Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. In March 2024, ESS Tech had US$90m in cash, and was debt-free. In the last year, its cash burn was US$59m. Therefore, from March 2024 it had roughly 18 months of cash runway. 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 Well Is ESS Tech Growing?

It was fairly positive to see that ESS Tech reduced its cash burn by 36% during the last year. But that's nothing compared to its mouth-watering operating revenue growth of 682%. We think it is growing rather well, upon reflection. 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.

Can ESS Tech Raise More Cash Easily?

ESS Tech 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. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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.

Since it has a market capitalisation of US$139m, ESS Tech's US$59m in cash burn equates to about 43% of its market value. From this perspective, it seems that the company spent a huge amount relative to its market value, and we'd be very wary of a painful capital raising.

Is ESS Tech's Cash Burn A Worry?

On this analysis of ESS Tech's cash burn, we think its revenue growth was reassuring, while its cash burn relative to its market cap has us a bit worried. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future.
