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 note that Waste Connections, Inc. (NYSE:WCN) does have debt on its balance sheet. But should shareholders be worried about its use of debt?

When Is Debt Dangerous?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth 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 Waste Connections's Net Debt?

As you can see below, at the end of June 2024, Waste Connections had US$7.71b of debt, up from US$6.70b a year ago. Click the image for more detail. Net debt is about the same, since the it doesn't have much cash.

How Strong Is Waste Connections' Balance Sheet?

Zooming in on the latest balance sheet data, we can see that Waste Connections had liabilities of US$1.77b due within 12 months and liabilities of US$9.55b due beyond that. On the other hand, it had cash of US$97.1m and US$961.5m worth of receivables due within a year. So it has liabilities totalling US$10.3b more than its cash and near-term receivables, combined.

This deficit isn't so bad because Waste Connections is worth a massive US$46.2b, 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 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). 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).

Waste Connections's debt is 3.0 times its EBITDA, and its EBIT cover its interest expense 5.1 times over. Taken together this implies that, while we wouldn't want to see debt levels rise, we think it can handle its current leverage. Waste Connections grew its EBIT by 8.0% in the last year. Whilst that hardly knocks our socks off it is a positive when it comes to debt. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Waste Connections 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.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Waste Connections generated free cash flow amounting to a very robust 84% of its EBIT, more than we'd expect. That puts it in a very strong position to pay down debt.

Our View

Waste Connections's conversion of EBIT to free cash flow suggests it can handle its debt as easily as Cristiano Ronaldo could score a goal against an under 14's goalkeeper. But truth be told we feel its net debt to EBITDA does undermine this impression a bit. All these things considered, it appears that Waste Connections 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. 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.
