Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' So it seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. Importantly, Charles River Laboratories International, Inc. (NYSE:CRL) does carry debt. But the real question is whether this debt is making the company risky.

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. While that is not too common, we often do see indebted companies permanently diluting shareholders because lenders force them to raise capital at a distressed price. 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. When we think about a company's use of debt, we first look at cash and debt together.

What Is Charles River Laboratories International's Net Debt?

The chart below, which you can click on for greater detail, shows that Charles River Laboratories International had US$2.62b in debt in December 2023; about the same as the year before. However, because it has a cash reserve of US$276.8m, its net debt is less, at about US$2.35b.

How Healthy Is Charles River Laboratories International's Balance Sheet?

According to the last reported balance sheet, Charles River Laboratories International had liabilities of US$1.06b due within 12 months, and liabilities of US$3.48b due beyond 12 months. Offsetting these obligations, it had cash of US$276.8m as well as receivables valued at US$780.4m due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$3.48b.

This deficit isn't so bad because Charles River Laboratories International is worth a massive US$13.6b, and thus could probably raise enough capital to shore up 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 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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Charles River Laboratories International 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 5.0 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. Notably Charles River Laboratories International's EBIT was pretty flat over the last year. We would prefer to see some earnings growth, because that always helps diminish debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Charles River Laboratories International's ability to maintain a healthy balance sheet going forward. So if you're focused on the future you can check out this free report showing analyst profit forecasts.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So it's worth checking how much of that EBIT is backed by free cash flow. During the last three years, Charles River Laboratories International produced sturdy free cash flow equating to 61% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.

Our View

On our analysis Charles River Laboratories International's conversion of EBIT to free cash flow should signal that it won't have too much trouble with its debt. But the other factors we noted above weren't so encouraging. For instance it seems like it has to struggle a bit handle its debt, based on its EBITDA,. When we consider all the factors mentioned above, we do feel a bit cautious about Charles River Laboratories International's use of debt. While debt does have its upside in higher potential returns, we think shareholders should definitely consider how debt levels might make the stock more risky. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet. These risks can be hard to spot. Every company has them, and we've spotted 2 warning signs for Charles River Laboratories International you should know about.
