There’s no doubt that money can be built by owning shares of unprofitable businesses. 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 creating company burns through its cash too quickly.
So, the natural question for Cabaletta Bio (NASDAQ:CABA) shareholders is whether they should be concerned by its rate of cash burn. For the purpose of this article, we’ll define cash burn as the amount of cash the company is spfinishing each year to fund its growth (also called its negative free cash flow). Let’s start with an examination of the business’ cash, relative to its cash burn.
