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 Guizhou Gas Group Corporation Ltd. (SHSE:600903) does use debt in its business. But should shareholders be worried about its use of debt?

Why Does Debt Bring Risk?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. Of course, the upside of debt is that it often represents cheap capital, especially when it replaces dilution in a company with the ability to reinvest 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 Guizhou Gas Group's Net Debt?

The image below, which you can click on for greater detail, shows that at September 2024 Guizhou Gas Group had debt of CN¥5.03b, up from CN¥4.69b in one year. However, it does have CN¥643.8m in cash offsetting this, leading to net debt of about CN¥4.39b.

How Healthy Is Guizhou Gas Group's Balance Sheet?

We can see from the most recent balance sheet that Guizhou Gas Group had liabilities of CN¥3.25b falling due within a year, and liabilities of CN¥3.36b due beyond that. On the other hand, it had cash of CN¥643.8m and CN¥944.9m worth of receivables due within a year. So its liabilities total CN¥5.02b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because Guizhou Gas Group is worth CN¥8.45b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Guizhou Gas Group shareholders face the double whammy of a high net debt to EBITDA ratio (7.0), and fairly weak interest coverage, since EBIT is just 1.9 times the interest expense. This means we'd consider it to have a heavy debt load. Even worse, Guizhou Gas Group saw its EBIT tank 47% over the last 12 months. If earnings continue to follow that trajectory, paying off that debt load will be harder than convincing us to run a marathon in the rain. The balance sheet is clearly the area to focus on when you are analysing debt. But it is Guizhou Gas Group'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. Click here for an interactive snapshot.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the last three years, Guizhou Gas Group saw substantial negative free cash flow, in total. While investors are no doubt expecting a reversal of that situation in due course, it clearly does mean its use of debt is more risky.

Our View

On the face of it, Guizhou Gas Group's conversion of EBIT to free cash flow left us tentative about the stock, and its EBIT growth rate was no more enticing than the one empty restaurant on the busiest night of the year. And furthermore, its interest cover also fails to instill confidence. After considering the datapoints discussed, we think Guizhou Gas Group has too much debt. That sort of riskiness is ok for some, but it certainly doesn't float our boat. There's no doubt that we learn most about debt from the balance sheet. But ultimately, every company can contain risks that exist outside of the balance sheet. We've identified 3 warning signs with Guizhou Gas Group (at least 2 which are potentially serious) , and understanding them should be part of your investment process.
