Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 Clean Harbors, Inc. (NYSE:CLH) does use debt in its business. But should shareholders be worried about its use of debt?

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 usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we think about a company's use of debt, we first look at cash and debt together.

What Is Clean Harbors's Debt?

As you can see below, at the end of March 2024, Clean Harbors had US$2.79b of debt, up from US$2.42b a year ago. Click the image for more detail. However, it does have US$442.6m in cash offsetting this, leading to net debt of about US$2.35b.

A Look At Clean Harbors' Liabilities

We can see from the most recent balance sheet that Clean Harbors had liabilities of US$1.02b falling due within a year, and liabilities of US$3.61b due beyond that. Offsetting this, it had US$442.6m in cash and US$1.21b in receivables that were due within 12 months. So its liabilities total US$2.98b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because Clean Harbors is worth a massive US$12.2b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. But it's clear that we should definitely closely examine whether it can manage its debt without dilution.

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 2.4 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. Unfortunately, Clean Harbors saw its EBIT slide 7.7% in the last twelve months. If that earnings trend continues then its debt load will grow heavy like the heart of a polar bear watching its sole cub. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Clean Harbors can strengthen its balance sheet over time.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. In the last three years, Clean Harbors's free cash flow amounted to 42% of its EBIT, less than we'd expect. That weak cash conversion makes it more difficult to handle indebtedness.

Our View

Clean Harbors's EBIT growth rate was a real negative on this analysis, although the other factors we considered cast it in a significantly better light. But on the bright side, its ability to to handle its total liabilities isn't too shabby at all. We think that Clean Harbors's debt does make it a bit risky, after considering the aforementioned data points together. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it.
