We Think Cartesian Therapeutics (NASDAQ:RNAC) Can Afford To Drive Business 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 Cartesian Therapeutics (NASDAQ:RNAC) 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. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

How Long Is Cartesian Therapeutics' Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Cartesian Therapeutics last reported its June 2025 balance sheet in August 2025, it had zero debt and cash worth US$160m. In the last year, its cash burn was US$45m. Therefore, from June 2025 it had 3.6 years of cash runway. A runway of this length affords the company the time and space it needs to develop the business. Depicted below, you can see how its cash holdings have changed over time.

How Well Is Cartesian Therapeutics Growing?

We reckon the fact that Cartesian Therapeutics managed to shrink its cash burn by 32% over the last year is rather encouraging. On the other hand, operating revenue was down 98% during the period, which is seriously uninspiring. Considering both these metrics, we're a little concerned about how the company is developing. 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.

How Easily Can Cartesian Therapeutics Raise Cash?

Cartesian Therapeutics 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. Commonly, a business will sell new shares in itself to raise cash and drive growth. We can compare a company's cash burn to its market capitalisation to get a sense for how many new shares a company would have to issue to fund one year's operations.

Cartesian Therapeutics has a market capitalisation of US$269m and burnt through US$45m last year, which is 17% of the company's market value. Given that situation, it's fair to say the company wouldn't have much trouble raising more cash for growth, but shareholders would be somewhat diluted.

How Risky Is Cartesian Therapeutics' Cash Burn Situation?

Even though its falling revenue makes us a little nervous, we are compelled to mention that we thought Cartesian Therapeutics' cash runway was relatively promising. Cash burning companies are always on the riskier side of things, but after considering all of the factors discussed in this short piece, we're not too worried about its rate of cash burn. On another note, Cartesian Therapeutics has 5 warning signs (and 2 which are a bit unpleasant) we think you should know about.
