We Think Atea Pharmaceuticals (NASDAQ:AVIR) Needs To Drive Business Growth Carefully

We can readily understand why investors are attracted to unprofitable companies. 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. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

For the purpose of this article, we’ll define cash burn as the amount of cash the company is spending each year to fund its growth (also called its negative free cash flow).

How Is Atea Pharmaceuticals’ Cash Burn Changing Over Time?

Atea Pharmaceuticals didn’t record any revenue over the last year, indicating that it’s an early stage company still developing its business. Nonetheless, we can still examine its cash burn trajectory as part of our assessment of its cash burn situation. With the cash burn rate up 17% in the last year, it seems that the company is ratcheting up investment in the business over time. That’s not necessarily a bad thing, but investors should be mindful of the fact that will shorten the cash runway.

How Easily Can Atea Pharmaceuticals Raise Cash?

While Atea Pharmaceuticals does have a solid cash runway, its cash burn trajectory may have some shareholders thinking ahead to when the company may need to raise more cash. Companies can raise capital through either debt or equity. Many companies end up issuing new shares to fund future 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$440m, Atea Pharmaceuticals’ US$148m in cash burn equates to about 34% of its market value. That’s fairly notable cash burn, so if the company had to sell shares to cover the cost of another year’s operations, shareholders would suffer some costly dilution.
