Is ESS Tech (NYSE:GWH) In A Good Position To Invest In Growth?

Just because a business does not make any money, does not mean that the stock will go down. 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 should ESS Tech (NYSE:GWH) shareholders be worried about its 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 ESS Tech Have A Long Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at September 2023, ESS Tech had cash of US$125m and no debt. Importantly, its cash burn was US$71m over the trailing twelve months. Therefore, from September 2023 it had roughly 21 months of cash runway. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. Depicted below, you can see how its cash holdings have changed over time.

How Is ESS Tech's Cash Burn Changing Over Time?

Whilst it's great to see that ESS Tech has already begun generating revenue from operations, last year it only produced US$4.8m, so we don't think it is generating significant revenue, at this point. Therefore, for the purposes of this analysis we'll focus on how the cash burn is tracking. While it hardly paints a picture of imminent growth, the fact that it has reduced its cash burn by 24% over the last year suggests some degree of prudence. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Easily Can ESS Tech Raise Cash?

While ESS Tech is showing a solid reduction in its cash burn, it's still worth considering how easily it could raise more cash, even just to fuel 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. 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.

ESS Tech has a market capitalisation of US$204m and burnt through US$71m last year, which is 35% of the company's market value. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.

So, Should We Worry About ESS Tech's Cash Burn?

Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought ESS Tech's cash runway was relatively promising. 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.
