Is Greenstone Resources (ASX:GSR) In A Good Position To Invest In Growth?

There's no doubt that money can be made by owning shares of unprofitable businesses. For example, biotech and mining exploration companies often lose money for years before finding success with a new treatment or mineral discovery. But while history lauds those rare successes, those that fail are often forgotten; who remembers Pets.com?

So should Greenstone Resources (ASX:GSR) shareholders 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. We'll start by comparing its cash burn with its cash reserves in order to calculate its cash runway.

How Long Is Greenstone Resources' Cash Runway?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Greenstone Resources last reported its balance sheet in December 2021, it had zero debt and cash worth AU$1.4m. Importantly, its cash burn was AU$1.8m over the trailing twelve months. Therefore, from December 2021 it had roughly 10 months of cash runway. To be frank, this kind of short runway puts us on edge, as it indicates the company must reduce its cash burn significantly, or else raise cash imminently. You can see how its cash balance has changed over time in the image below.

How Is Greenstone Resources' Cash Burn Changing Over Time?

Because Greenstone Resources 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. 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. Greenstone Resources makes us a little nervous due to its lack of substantial operating revenue. So we'd generally prefer stocks from this list of stocks that have analysts forecasting growth.

How Easily Can Greenstone Resources Raise Cash?

Given its cash burn trajectory, Greenstone Resources shareholders should already be thinking about how easy it might be for it to raise further cash in the future. Companies can raise capital through either debt or equity. 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.

Greenstone Resources' cash burn of AU$1.8m is about 5.5% of its AU$32m market capitalisation. 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.
