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.' So it might be obvious that you need to consider debt, when you think about how risky any given stock is, because too much debt can sink a company. As with many other companies Eaton Corporation plc (NYSE:ETN) makes use of debt. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Eaton's Net Debt?

As you can see below, at the end of September 2024, Eaton had US$9.40b of debt, up from US$8.17b a year ago. Click the image for more detail. However, it also had US$1.99b in cash, and so its net debt is US$7.40b.

How Strong Is Eaton's Balance Sheet?

According to the last reported balance sheet, Eaton had liabilities of US$7.94b due within 12 months, and liabilities of US$12.1b due beyond 12 months. Offsetting this, it had US$1.99b in cash and US$5.24b in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$12.8b.

Since publicly traded Eaton shares are worth a very impressive total of US$133.6b, it seems unlikely that this level of liabilities would be a major threat. But there are sufficient liabilities that we would certainly recommend shareholders continue to monitor the balance sheet, going forward.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). This way, we consider both the absolute quantum of the debt, as well as the interest rates paid on it.

Eaton's net debt is only 1.4 times its EBITDA. And its EBIT covers its interest expense a whopping 34.9 times over. So we're pretty relaxed about its super-conservative use of debt. Also positive, Eaton grew its EBIT by 22% in the last year, and that should make it easier to pay down debt, going forward. The balance sheet is clearly the area to focus on when you are analysing debt. But it is future earnings, more than anything, that will determine Eaton's ability to maintain a healthy balance sheet going forward.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Eaton produced sturdy free cash flow equating to 69% of its EBIT, about what we'd expect. This free cash flow puts the company in a good position to pay down debt, when appropriate.

Our View

Happily, Eaton's impressive interest cover implies it has the upper hand on its debt. And that's just the beginning of the good news since its EBIT growth rate is also very heartening. Looking at the bigger picture, we think Eaton's use of debt seems quite reasonable and we're not concerned about it. After all, sensible leverage can boost returns on equity. When analysing debt levels, the balance sheet is the obvious place to start. However, not all investment risk resides within the balance sheet - far from it.
