We can readily understand why investors are attracted to unprofitable companies. 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. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

So, the natural question for SES AI (NYSE:SES) 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. First, we'll determine its cash runway by comparing its cash burn with its cash reserves.

Does SES AI 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. When SES AI last reported its December 2023 balance sheet in February 2024, it had zero debt and cash worth US$332m. In the last year, its cash burn was US$72m. So it had a cash runway of about 4.6 years from December 2023. A runway of this length affords the company the time and space it needs to develop the business. The image below shows how its cash balance has been changing over the last few years.

How Is SES AI's Cash Burn Changing Over Time?

SES AI didn't record any revenue over the last year, indicating that it's an early stage company still developing its business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. Over the last year its cash burn actually increased by 18%, which suggests that management are increasing investment in future growth, but not too quickly. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. 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.

Can SES AI Raise More Cash Easily?

While SES AI does have a solid cash runway, its cash burn trajectory may have some shareholders thinking ahead to when the company may need to raise more cash. 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.

SES AI has a market capitalisation of US$550m and burnt through US$72m last year, which is 13% of the company's market value. As a result, we'd venture that the company could raise more cash for growth without much trouble, albeit at the cost of some dilution.

How Risky Is SES AI's Cash Burn Situation?

It may already be apparent to you that we're relatively comfortable with the way SES AI is burning through its cash. In particular, we think its cash runway stands out as evidence that the company is well on top of its spending. Although its increasing cash burn does give us reason for pause, the other metrics we discussed in this article form a positive picture overall. Considering all the factors discussed in this article, we're not overly concerned about the company's cash burn, although we do think shareholders should keep an eye on how it develops. On another note, SES AI has 4 warning signs (and 2 which shouldn't be ignored) we think you should know about.
