Here's Why We're Watching Protara Therapeutics' (NASDAQ:TARA) Cash Burn Situation

We can readily understand why investors are attracted to unprofitable companies. 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. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

Given this risk, we thought we'd take a look at whether Protara Therapeutics (NASDAQ:TARA) shareholders should be worried about its cash burn. For the purposes of this article, cash burn is the annual rate at which an unprofitable company spends cash to fund its growth; its negative free cash flow. The first step is to compare its cash burn with its cash reserves, to give us its 'cash runway'.

When Might Protara Therapeutics Run Out Of Money?

A company's cash runway is the amount of time it would take to burn through its cash reserves at its current cash burn rate. When Protara Therapeutics last reported its balance sheet in September 2023, it had zero debt and cash worth US$74m. In the last year, its cash burn was US$34m. That means it had a cash runway of about 2.2 years as of September 2023. Arguably, that's a prudent and sensible length of runway to have. The image below shows how its cash balance has been changing over the last few years.

How Is Protara Therapeutics' Cash Burn Changing Over Time?

Protara 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 19% 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. 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 Protara Therapeutics To Raise More Cash For Growth?

While Protara 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. 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. 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.

Protara Therapeutics has a market capitalisation of US$20m and burnt through US$34m last year, which is 168% of the company's market value. Given just how high that expenditure is, relative to the company's market value, we think there's an elevated risk of funding distress, and we would be very nervous about holding the stock.

Is Protara Therapeutics' Cash Burn A Worry?

Even though its cash burn relative to its market cap makes us a little nervous, we are compelled to mention that we thought Protara Therapeutics' cash runway was relatively promising. Looking at the factors mentioned in this short report, we do think that its cash burn is a bit risky, and it does make us slightly nervous about the stock.
