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 SES AI (NYSE:SES) shareholders should be worried about its cash burn. In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. 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 company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. In September 2023, SES AI had US$342m in cash, and was debt-free. Looking at the last year, the company burnt through US$69m. Therefore, from September 2023 it had 5.0 years of cash runway. A runway of this length affords the company the time and space it needs to develop the business. You can see how its cash balance has changed over time in the image below.

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. With the cash burn rate up 4.9% in the last year, it seems that the company is ratcheting up investment in the business over time. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. While the past is always worth studying, it is the future that matters most of all. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Hard Would It Be For SES AI To Raise More Cash For Growth?

Since its cash burn is increasing (albeit only slightly), SES AI shareholders should still be mindful of the possibility it will require more cash in the future. Companies can raise capital through either debt or equity. 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$876m, SES AI's US$69m in cash burn equates to about 7.9% of its market value. Given that is a rather small percentage, it would probably be really easy for the company to fund another year's growth by issuing some new shares to investors, or even by taking out a loan.

How Risky Is SES AI's Cash Burn Situation?

As you can probably tell by now, we're not too worried about SES AI's cash burn. In particular, we think its cash runway stands out as evidence that the company is well on top of its spending. While its increasing cash burn wasn't great, the other factors mentioned in this article more than make up for weakness on that measure. After taking into account the various metrics mentioned in this report, we're pretty comfortable with how the company is spending its cash, as it seems on track to meet its needs over the medium term. On another note, SES AI has 4 warning signs (and 2 which don't sit too well with us) we think you should know about.
