Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 Ecolab Inc. (NYSE:ECL) does use debt in its business. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

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. 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, debt can be an important tool in businesses, particularly capital heavy businesses. When we think about a company's use of debt, we first look at cash and debt together.

What Is Ecolab's Net Debt?

As you can see below, Ecolab had US$7.53b of debt at June 2024, down from US$8.61b a year prior. However, it also had US$384.0m in cash, and so its net debt is US$7.14b.

A Look At Ecolab's Liabilities

According to the last reported balance sheet, Ecolab had liabilities of US$3.85b due within 12 months, and liabilities of US$9.31b due beyond 12 months. Offsetting this, it had US$384.0m in cash and US$3.04b in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$9.73b.

Of course, Ecolab has a titanic market capitalization of US$72.1b, so these liabilities are probably manageable. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

With a debt to EBITDA ratio of 2.1, Ecolab uses debt artfully but responsibly. And the fact that its trailing twelve months of EBIT was 8.5 times its interest expenses harmonizes with that theme. We note that Ecolab grew its EBIT by 27% in the last year, and that should make it easier to pay down debt, going forward. 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 Ecolab can strengthen its balance sheet over time.

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. During the last three years, Ecolab produced sturdy free cash flow equating to 70% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.

Our View

The good news is that Ecolab's demonstrated ability to grow its EBIT delights us like a fluffy puppy does a toddler. And that's just the beginning of the good news since its conversion of EBIT to free cash flow is also very heartening. Looking at the bigger picture, we think Ecolab's use of debt seems quite reasonable and we're not concerned about it. While debt does bring risk, when used wisely it can also bring a higher return on equity. 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. For example - Ecolab has 1 warning sign we think you should be aware of.
