Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. We can see that PolarX Limited (ASX:PXX) does use debt in its business. But should shareholders be worried about its use of debt?
When Is Debt Dangerous?
Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.
What Is PolarX's Debt?
As you can see below, at the end of June 2025, PolarX had AU$3.06m of debt, up from none a year ago. Click the image for more detail. However, it also had AU$2.86m in cash, and so its net debt is AU$204.2k.
A Look At PolarX's Liabilities
Zooming in on the latest balance sheet data, we can see that PolarX had liabilities of AU$3.20m due within 12 months and no liabilities due beyond that. On the other hand, it had cash of AU$2.86m and AU$38.1k worth of receivables due within a year. So it has liabilities totalling AU$306.1k more than its cash and near-term receivables, combined.
Having regard to PolarX's size, it seems that its liquid assets are well balanced with its total liabilities. So it's very unlikely that the AU$51.6m company is short on cash, but still worth keeping an eye on the balance sheet. But either way, PolarX has virtually no net debt, so it's fair to say it does not have a heavy debt load! There's no doubt that we learn most about debt from the balance sheet. But it is PolarX's earnings that will influence how the balance sheet holds up in the future. So when considering debt, it's definitely worth looking at the earnings trend.

Since PolarX has no significant operating revenue, shareholders probably hope it will develop a valuable new mine before too long.
Caveat Emptor
Over the last twelve months PolarX produced an earnings before interest and tax (EBIT) loss. To be specific the EBIT loss came in at AU$1.7m. When we look at that and recall the liabilities on its balance sheet, relative to cash, it seems unwise to us for the company to have any debt. So we think its balance sheet is a little strained, though not beyond repair. However, it doesn't help that it burned through AU$4.8m of cash over the last year. So suffice it to say we consider the stock very risky. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it. Case in point: We've spotted 4 warning signs for PolarX you should be aware of, and 2 of them make us uncomfortable.
