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.' 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. We can see that Caterpillar Inc. (NYSE:CAT) does use debt in its business. But should shareholders be worried about its use of debt?

Why Does Debt Bring Risk?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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 Caterpillar's Net Debt?

The chart below, which you can click on for greater detail, shows that Caterpillar had US$37.9b in debt in March 2024; about the same as the year before. However, it also had US$4.36b in cash, and so its net debt is US$33.5b.

How Strong Is Caterpillar's Balance Sheet?

The latest balance sheet data shows that Caterpillar had liabilities of US$32.4b due within a year, and liabilities of US$33.7b falling due after that. Offsetting these obligations, it had cash of US$4.36b as well as receivables valued at US$9.49b due within 12 months. So its liabilities total US$52.2b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because Caterpillar is worth a massive US$164.3b, 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.

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.

We'd say that Caterpillar's moderate net debt to EBITDA ratio ( being 2.1), indicates prudence when it comes to debt. And its strong interest cover of 1k times, makes us even more comfortable. We note that Caterpillar grew its EBIT by 25% in the last year, and that should make it easier to pay down debt, going forward. There's no doubt that we learn most about debt from the balance sheet. But ultimately the future profitability of the business will decide if Caterpillar can strengthen its balance sheet over time.

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, Caterpillar recorded free cash flow worth 59% 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

The good news is that Caterpillar's demonstrated ability to cover its interest expense with its EBIT delights us like a fluffy puppy does a toddler. And the good news does not stop there, as its EBIT growth rate also supports that impression! When we consider the range of factors above, it looks like Caterpillar is pretty sensible with its use of debt. While that brings some risk, it can also enhance returns for shareholders. 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.
