We Think Tectonic Therapeutic (NASDAQ:TECX) 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, although Amazon.com made losses for many years after listing, if you had bought and held the shares since 1999, you would have made a fortune. Nonetheless, only a fool would ignore the risk that a loss making company burns through its cash too quickly.

So, the natural question for Tectonic Therapeutic (NASDAQ:TECX) shareholders is whether they should be concerned by its rate of cash burn. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. Let's start with an examination of the business' cash, relative to its cash burn.

How Is Tectonic Therapeutic's Cash Burn Changing Over Time?

Because Tectonic Therapeutic isn't currently generating revenue, we consider it an early-stage business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. Over the last year its cash burn actually increased by a very significant 61%. While this spending increase is no doubt intended to drive growth, if the trend continues the company's cash runway will shrink very quickly. While the past is always worth studying, it is the future that matters most of all. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Hard Would It Be For Tectonic Therapeutic To Raise More Cash For Growth?

Given its cash burn trajectory, Tectonic Therapeutic shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. 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. 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$392m, Tectonic Therapeutic's US$63m in cash burn equates to about 16% of its 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.
