Legendary fund manager Li Lu (who Charlie Munger backed) once said, 'The biggest investment risk is not the volatility of prices, but whether you will suffer a permanent loss of capital.' When we think about how risky a company is, we always like to look at its use of debt, since debt overload can lead to ruin. As with many other companies Republic Services, Inc. (NYSE:RSG) makes use of debt. But is this debt a concern to shareholders?

Why Does Debt Bring Risk?

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, 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 think about a company's use of debt, we first look at cash and debt together.

What Is Republic Services's Debt?

The image below, which you can click on for greater detail, shows that at March 2024 Republic Services had debt of US$12.6b, up from US$12.0b in one year. And it doesn't have much cash, so its net debt is about the same.

How Healthy Is Republic Services' Balance Sheet?

According to the last reported balance sheet, Republic Services had liabilities of US$4.33b due within 12 months, and liabilities of US$16.2b due beyond 12 months. Offsetting this, it had US$91.6m in cash and US$1.92b in receivables that were due within 12 months. So its liabilities total US$18.6b more than the combination of its cash and short-term receivables.

Republic Services has a very large market capitalization of US$61.2b, so it could very likely raise cash to ameliorate 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.

In order to size up a company's debt relative to its earnings, we calculate its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and its earnings before interest and tax (EBIT) divided by its interest expense (its interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Republic Services's debt is 2.8 times its EBITDA, and its EBIT cover its interest expense 5.7 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. If Republic Services can keep growing EBIT at last year's rate of 14% over the last year, then it will find its debt load easier to manage. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine Republic Services's ability to maintain a healthy balance sheet going forward.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Republic Services recorded free cash flow worth 67% 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

Republic Services'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, on a more sombre note, we are a little concerned by its net debt to EBITDA. Looking at all the aforementioned factors together, it strikes us that Republic Services can handle its debt fairly comfortably. 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. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately, every company can contain risks that exist outside of the balance sheet.
