Warren Buffett famously said, 'Volatility is far from synonymous with risk.' 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 Darling Ingredients Inc. (NYSE:DAR) makes use of debt. But should shareholders be worried about its use of debt?

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, debt can be an important tool in businesses, particularly capital heavy businesses. The first step when considering a company's debt levels is to consider its cash and debt together.

How Much Debt Does Darling Ingredients Carry?

As you can see below, at the end of December 2023, Darling Ingredients had US$4.41b of debt, up from US$3.38b a year ago. Click the image for more detail. On the flip side, it has US$126.5m in cash leading to net debt of about US$4.29b.

A Look At Darling Ingredients' Liabilities

We can see from the most recent balance sheet that Darling Ingredients had liabilities of US$998.1m falling due within a year, and liabilities of US$5.37b due beyond that. On the other hand, it had cash of US$126.5m and US$821.9m worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$5.42b.

This deficit is considerable relative to its market capitalization of US$7.09b, so it does suggest shareholders should keep an eye on Darling Ingredients' use of debt. Should its lenders demand that it shore up the balance sheet, shareholders would likely face severe 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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

While we wouldn't worry about Darling Ingredients's net debt to EBITDA ratio of 3.9, we think its super-low interest cover of 2.3 times is a sign of high leverage. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Investors should also be troubled by the fact that Darling Ingredients saw its EBIT drop by 14% over the last twelve months. If things keep going like that, handling the debt will about as easy as bundling an angry house cat into its travel box. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Darling Ingredients's ability to maintain a healthy balance sheet going forward. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

Finally, while the tax-man may adore accounting profits, lenders only accept cold hard cash. So it's worth checking how much of that EBIT is backed by free cash flow. Over the most recent three years, Darling Ingredients recorded free cash flow worth 65% of its EBIT, which is around normal, given free cash flow excludes interest and tax. This cold hard cash means it can reduce its debt when it wants to.

Our View

To be frank both Darling Ingredients's EBIT growth rate and its track record of covering its interest expense with its EBIT make us rather uncomfortable with its debt levels. But at least it's pretty decent at converting EBIT to free cash flow; that's encouraging. Looking at the balance sheet and taking into account all these factors, we do believe that debt is making Darling Ingredients stock a bit risky. Some people like that sort of risk, but we're mindful of the potential pitfalls, so we'd probably prefer it carry less debt. 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 instance, we've identified 1 warning sign for Darling Ingredients that you should be aware of.
