We Think Protagonist Therapeutics (NASDAQ:PTGX) Can Afford To Drive Business Growth

We can readily understand why investors are attracted to unprofitable companies. Indeed, Protagonist Therapeutics (NASDAQ:PTGX) stock is up 110% in the last year, providing strong gains for shareholders. Having said that, unprofitable companies are risky because they could potentially burn through all their cash and become distressed.

Given its strong share price performance, we think it's worthwhile for Protagonist Therapeutics shareholders to consider whether its cash burn is concerning. In this report, we will consider the company's annual negative free cash flow, henceforth referring to it as the 'cash burn'. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

How Long Is Protagonist Therapeutics' Cash Runway?

You can calculate a company's cash runway by dividing the amount of cash it has by the rate at which it is spending that cash. In September 2023, Protagonist Therapeutics had US$321m in cash, and was debt-free. Looking at the last year, the company burnt through US$119m. That means it had a cash runway of about 2.7 years as of September 2023. That's decent, giving the company a couple years to develop its business. Depicted below, you can see how its cash holdings have changed over time.

How Is Protagonist Therapeutics' Cash Burn Changing Over Time?

Protagonist Therapeutics 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 14% in the last year, it seems that the company is ratcheting up investment in the business over time. However, the company's true cash runway will therefore be shorter than suggested above, if spending continues to increase. 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 Easily Can Protagonist Therapeutics Raise Cash?

While Protagonist Therapeutics 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. 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.

Protagonist Therapeutics has a market capitalisation of US$1.4b and burnt through US$119m last year, which is 8.8% of the company's market value. Given that is a rather small percentage, it would probably be really easy for the company to fund another year's growth by issuing some new shares to investors, or even by taking out a loan.

Is Protagonist Therapeutics' Cash Burn A Worry?

As you can probably tell by now, we're not too worried about Protagonist Therapeutics' cash burn. For example, we think its cash runway suggests that the company is on a good path. Although its increasing cash burn does give us reason for pause, the other metrics we discussed in this article form a positive picture overall. Based on the factors mentioned in this article, we think its cash burn situation warrants some attention from shareholders, but we don't think they should be worried.
