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. We can see that Darling Ingredients Inc. (NYSE:DAR) does use debt in its business. 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 frequent (but still costly) occurrence is where a company must issue shares at bargain-basement prices, permanently diluting shareholders, just to shore up its balance sheet. Of course, plenty of companies use debt to fund growth, without any negative consequences. When we examine debt levels, we first consider both cash and debt levels, together.

How Much Debt Does Darling Ingredients Carry?

As you can see below, Darling Ingredients had US$4.24b of debt, at September 2024, which is about the same as the year before. You can click the chart for greater detail. On the flip side, it has US$114.8m in cash leading to net debt of about US$4.13b.

How Strong Is Darling Ingredients' Balance Sheet?

The latest balance sheet data shows that Darling Ingredients had liabilities of US$1.06b due within a year, and liabilities of US$4.88b falling due after that. Offsetting these obligations, it had cash of US$114.8m as well as receivables valued at US$616.7m due within 12 months. So its liabilities total US$5.21b more than the combination of its cash and short-term receivables.

This deficit is considerable relative to its market capitalization of US$5.50b, so it does suggest shareholders should keep an eye on Darling Ingredients' use of debt. This suggests shareholders would be heavily diluted if the company needed to shore up its balance sheet in a hurry.

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). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

While Darling Ingredients's debt to EBITDA ratio (4.8) suggests that it uses some debt, its interest cover is very weak, at 1.3, suggesting high leverage. In large part that's due to the company's significant depreciation and amortisation charges, which arguably mean its EBITDA is a very generous measure of earnings, and its debt may be more of a burden than it first appears. So shareholders should probably be aware that interest expenses appear to have really impacted the business lately. Worse, Darling Ingredients's EBIT was down 40% over the last year. If earnings continue to follow that trajectory, paying off that debt load will be harder than convincing us to run a marathon in the rain. 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 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.

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, Darling Ingredients 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

On the face of it, Darling Ingredients's interest cover left us tentative about the stock, and its EBIT growth rate was no more enticing than the one empty restaurant on the busiest night of the year. But at least it's pretty decent at converting EBIT to free cash flow; that's encouraging. Overall, we think it's fair to say that Darling Ingredients has enough debt that there are some real risks around the balance sheet. If everything goes well that may pay off but the downside of this debt is a greater risk of permanent losses. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. These risks can be hard to spot. Every company has them, and we've spotted 3 warning signs for Darling Ingredients (of which 1 is a bit concerning!) you should know about.
