Just because a business does not make any money, does not mean that the stock will go down. For example, although software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

Given this risk, we thought we'd take a look at whether MiNK Therapeutics (NASDAQ:INKT) shareholders should 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 MiNK Therapeutics' Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When MiNK Therapeutics last reported its March 2026 balance sheet in May 2026, it had zero debt and cash worth US$9.5m. Importantly, its cash burn was US$6.3m over the trailing twelve months. That means it had a cash runway of around 18 months as of March 2026. Notably, analysts forecast that MiNK Therapeutics will break even (at a free cash flow level) in about 4 years. That means unless the company reduces its cash burn quickly, it may well look to raise more cash. The image below shows how its cash balance has been changing over the last few years.

How Is MiNK Therapeutics' Cash Burn Changing Over Time?

Because MiNK Therapeutics isn't currently generating revenue, we consider it an early-stage business. So while we can't look to sales to understand growth, we can look at how the cash burn is changing to understand how expenditure is trending over time. Even though it doesn't get us excited, the 24% reduction in cash burn year on year does suggest the company can continue operating for quite some time. 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 MiNK Therapeutics Raise Cash?

While MiNK Therapeutics 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. 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. 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.

Since it has a market capitalisation of US$55m, MiNK Therapeutics' US$6.3m in cash burn equates to about 11% of its 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 MiNK Therapeutics' Cash Burn Situation?

The good news is that in our view MiNK Therapeutics' cash burn situation gives shareholders real reason for optimism. One the one hand we have its solid cash burn reduction, while on the other it can also boast very strong cash burn relative to its market cap. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. While we're the kind of investors who are always a bit concerned about the risks involved with cash burning companies, the metrics we have discussed in this article leave us relatively comfortable about MiNK Therapeutics' situation. On another note, MiNK Therapeutics has 6 warning signs (and 3 which are potentially serious) we think you should know about.
