We Think Atara Biotherapeutics (NASDAQ:ATRA) Needs To Drive Business Growth Carefully

Even when a business is losing money, it's possible for shareholders to make money if they buy a good business at the right price. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

Given this risk, we thought we'd take a look at whether Atara Biotherapeutics (NASDAQ:ATRA) shareholders should be worried about its cash burn. 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). We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

When Might Atara Biotherapeutics Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. Atara Biotherapeutics has such a small amount of debt that we'll set it aside, and focus on the US$348m in cash it held at June 2020. Importantly, its cash burn was US$242m over the trailing twelve months. Therefore, from June 2020 it had roughly 17 months of cash runway. While that cash runway isn't too concerning, sensible holders would be peering into the distance, and considering what happens if the company runs out of cash. Depicted below, you can see how its cash holdings have changed over time.

How Is Atara Biotherapeutics' Cash Burn Changing Over Time?

Because Atara Biotherapeutics 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. Cash burn was pretty flat over the last year, which suggests that management are holding spending steady while the business advances its strategy. While the past is always worth studying, it is the future that matters most of all. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

How Hard Would It Be For Atara Biotherapeutics To Raise More Cash For Growth?

Since its cash burn is increasing (albeit only slightly), Atara Biotherapeutics shareholders should still be mindful of the possibility it will require more cash in the future. Issuing new shares, or taking on debt, are the most common ways for a listed company to raise more money for its business. 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.

Atara Biotherapeutics has a market capitalisation of US$1.1b and burnt through US$242m last year, which is 22% of the company's market value. That's not insignificant, and if the company had to sell enough shares to fund another year's growth at the current share price, you'd likely witness fairly costly dilution.

So, Should We Worry About Atara Biotherapeutics' Cash Burn?

Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought Atara Biotherapeutics' cash runway was relatively promising. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future.
