The external fund manager backed by Berkshire Hathaway's Charlie Munger, Li Lu, makes no bones about it when he says 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We can see that Clean Harbors, Inc. (NYSE:CLH) does use debt in its business. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does Clean Harbors Carry?

You can click the graphic below for the historical numbers, but it shows that as of June 2022 Clean Harbors had US$2.53b of debt, an increase on US$1.58b, over one year. However, it also had US$415.4m in cash, and so its net debt is US$2.11b.

How Healthy Is Clean Harbors' Balance Sheet?

We can see from the most recent balance sheet that Clean Harbors had liabilities of US$990.1m falling due within a year, and liabilities of US$3.22b due beyond that. On the other hand, it had cash of US$415.4m and US$1.14b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$2.65b.

Clean Harbors has a market capitalization of US$6.47b, so it could very likely raise cash to ameliorate 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.

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). The advantage of this approach is that we take into account both the absolute quantum of debt (with net debt to EBITDA) and the actual interest expenses associated with that debt (with its interest cover ratio).

Clean Harbors has a debt to EBITDA ratio of 2.7 and its EBIT covered its interest expense 5.0 times. This suggests that while the debt levels are significant, we'd stop short of calling them problematic. Importantly, Clean Harbors grew its EBIT by 62% over the last twelve months, and that growth will make it easier to handle its debt. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Clean Harbors can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

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. Over the most recent three years, Clean Harbors recorded free cash flow worth 71% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Clean Harbors's EBIT growth rate suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. But, on a more sombre note, we are a little concerned by its net debt to EBITDA. All these things considered, it appears that Clean Harbors can comfortably handle its current debt levels. Of course, while this leverage can enhance returns on equity, it does bring more risk, so it's worth keeping an eye on this one. 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. For example Clean Harbors has 2 warning signs (and 1 which shouldn't be ignored) we think you should know about.

When all is said and done, sometimes its easier to focus on companies that don't even need debt. Readers can access a list of growth stocks with zero net debt 100% free, right now.
