Can Immuneering Raise More Cash Easily?

While Immuneering 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. Companies can raise capital through either debt or equity. 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.

Since it has a market capitalisation of US$451m, Immuneering's US$50m 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.
