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. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

So, the natural question for ZIOPHARM Oncology (NASDAQ:ZIOP) shareholders is whether they should be concerned by its rate of 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.

How Long Is ZIOPHARM Oncology's Cash Runway?

A cash runway is defined as the length of time it would take a company to run out of money if it kept spending at its current rate of cash burn. In March 2021, ZIOPHARM Oncology had US$100m in cash, and was debt-free. Importantly, its cash burn was US$72m over the trailing twelve months. Therefore, from March 2021 it had roughly 17 months of cash runway. That's not too bad, but it's fair to say the end of the cash runway is in sight, unless cash burn reduces drastically. Depicted below, you can see how its cash holdings have changed over time.

How Is ZIOPHARM Oncology's Cash Burn Changing Over Time?

Because ZIOPHARM Oncology 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. Over the last year its cash burn actually increased by a very significant 75%. Oftentimes, increased cash burn simply means a company is accelerating its business development, but one should always be mindful that this causes the cash runway to shrink. Clearly, however, the crucial factor is whether the company will grow its business going forward. For that reason, it makes a lot of sense to take a look at our analyst forecasts for the company.

Can ZIOPHARM Oncology Raise More Cash Easily?

While ZIOPHARM Oncology 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. Commonly, a business will sell new shares in itself to raise cash and drive growth. By comparing a company's annual cash burn to its total market capitalisation, we can estimate roughly how many shares it would have to issue in order to run the company for another year (at the same burn rate).

Since it has a market capitalisation of US$564m, ZIOPHARM Oncology's US$72m in cash burn equates to about 13% 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.
