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, 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 should Centaurus Metals (ASX:CTM) shareholders be worried about its cash burn? In this article, we define cash burn as its annual (negative) free cash flow, which is the amount of money a company spends each year to fund its growth. Let's start with an examination of the business' cash, relative to its cash burn.

How Long Is Centaurus Metals' 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. When Centaurus Metals last reported its balance sheet in June 2021, it had zero debt and cash worth AU$20m. Importantly, its cash burn was AU$14m over the trailing twelve months. That means it had a cash runway of around 17 months as of June 2021. 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 Centaurus Metals' Cash Burn Changing Over Time?

Because Centaurus Metals 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. During the last twelve months, its cash burn actually ramped up 94%. 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. 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.

Can Centaurus Metals Raise More Cash Easily?

Given its cash burn trajectory, Centaurus Metals shareholders may wish to consider how easily it could raise more cash, despite its solid cash runway. Companies can raise capital through either debt or equity. One of the main advantages held by publicly listed companies is that they can sell shares to investors to raise cash and fund 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.

Centaurus Metals has a market capitalisation of AU$387m and burnt through AU$14m last year, which is 3.6% 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.

So, Should We Worry About Centaurus Metals' Cash Burn?
