David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the permanent loss of capital.' 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. As with many other companies Clean Harbors, Inc. (NYSE:CLH) makes use of debt. But is this debt a concern to shareholders?

What Risk Does Debt Bring?

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. If things get really bad, the lenders can take control of the business. 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. 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. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Clean Harbors's Debt?

The image below, which you can click on for greater detail, shows that at September 2024 Clean Harbors had debt of US$2.79b, up from US$2.30b in one year. However, because it has a cash reserve of US$594.7m, its net debt is less, at about US$2.19b.

A Look At Clean Harbors' Liabilities

The latest balance sheet data shows that Clean Harbors had liabilities of US$1.12b due within a year, and liabilities of US$3.66b falling due after that. On the other hand, it had cash of US$594.7m and US$1.30b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$2.88b.

Clean Harbors has a very large market capitalization of US$12.4b, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. However, it is still worthwhile taking a close look at its ability to pay off debt.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Clean Harbors has net debt worth 2.0 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 5.3 times the interest expense. While these numbers do not alarm us, it's worth noting that the cost of the company's debt is having a real impact. One way Clean Harbors could vanquish its debt would be if it stops borrowing more but continues to grow EBIT at around 15%, as it did over the last year. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Clean Harbors's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

But our final consideration is also important, because a company cannot pay debt with paper profits; it needs cold hard cash. So we always check how much of that EBIT is translated into free cash flow. Looking at the most recent three years, Clean Harbors recorded free cash flow of 41% of its EBIT, which is weaker than we'd expect. That's not great, when it comes to paying down debt.

Our View

When it comes to the balance sheet, the standout positive for Clean Harbors was the fact that it seems able to grow its EBIT confidently. However, our other observations weren't so heartening. For instance it seems like it has to struggle a bit to convert EBIT to free cash flow. When we consider all the elements mentioned above, it seems to us that Clean Harbors is managing its debt quite well. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. For instance, we've identified 2 warning signs for Clean Harbors that you should be aware of.
