We Think Aptose Biosciences (TSE:APS) Needs To Drive Business Growth Carefully

There's no doubt that money can be made by owning shares of unprofitable businesses. For example, although software-as-a-service business Salesforce.com lost money for years while it grew recurring revenue, if you held shares since 2005, you'd have done very well indeed. But the harsh reality is that very many loss making companies burn through all their cash and go bankrupt.

So should Aptose Biosciences (TSE:APS) 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.

When Might Aptose Biosciences Run Out Of Money?

A company's cash runway is calculated by dividing its cash hoard by its cash burn. As at December 2021, Aptose Biosciences had cash of US$79m and no debt. In the last year, its cash burn was US$44m. So it had a cash runway of approximately 22 months from December 2021. Importantly, analysts think that Aptose Biosciences will reach cashflow breakeven in 4 years. Essentially, that means the company will either reduce its cash burn, or else require more cash. The image below shows how its cash balance has been changing over the last few years.

How Is Aptose Biosciences' Cash Burn Changing Over Time?

Aptose Biosciences 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 28% 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. So you might want to take a peek at how much the company is expected to grow in the next few years.

How Hard Would It Be For Aptose Biosciences To Raise More Cash For Growth?

While Aptose Biosciences 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. Commonly, a business will sell new shares in itself to raise cash and drive 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.

Aptose Biosciences' cash burn of US$44m is about 34% of its US$129m market capitalisation. That's fairly notable cash burn, so if the company had to sell shares to cover the cost of another year's operations, shareholders would suffer some costly dilution.

Is Aptose Biosciences' 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 Aptose Biosciences' cash runway was relatively promising. Shareholders can take heart from the fact that analysts are forecasting it will reach breakeven. Even though we don't think it has a problem with its cash burn, the analysis we've done in this article does suggest that shareholders should give some careful thought to the potential cost of raising more money in the future.
