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 the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.
Given this risk, we thought we'd take a look at whether Sienna Cancer Diagnostics (ASX:SDX) 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. Let's start with an examination of the business's cash, relative to its cash burn.

Does Sienna Cancer Diagnostics Have A Long Cash Runway?
A company's cash runway is calculated by dividing its cash hoard by its cash burn. When Sienna Cancer Diagnostics last reported its balance sheet in June 2019, it had zero debt and cash worth AU$4.5m. Looking at the last year, the company burnt through AU$3.1m. So it had a cash runway of approximately 17 months from June 2019. 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 Sienna Cancer Diagnostics's Cash Burn Changing Over Time?
In our view, Sienna Cancer Diagnostics doesn't yet produce significant amounts of operating revenue, since it reported just AU$531k in the last twelve months. As a result, we think it's a bit early to focus on the revenue growth, so we'll limit ourselves to looking at how the cash burn is changing over time. With the cash burn rate up 36% 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. Admittedly, we're a bit cautious of Sienna Cancer Diagnostics due to its lack of significant operating revenues. So we'd generally prefer stocks from this list of stocks that have analysts forecasting growth.
How Easily Can Sienna Cancer Diagnostics Raise Cash?
While Sienna Cancer Diagnostics 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. Generally speaking, a listed business can raise new cash through issuing shares or taking on debt. 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.
