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. Importantly, Weatherford International plc (NASDAQ:WFRD) does carry debt. But the more important question is: how much risk is that debt creating?

What Risk Does Debt Bring?

Debt assists a business until the business has trouble paying it off, either with new capital or with free cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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 Weatherford International's Debt?

As you can see below, Weatherford International had US$1.59b of debt at June 2024, down from US$1.97b a year prior. However, it also had US$862.0m in cash, and so its net debt is US$726.0m.

A Look At Weatherford International's Liabilities

The latest balance sheet data shows that Weatherford International had liabilities of US$1.69b due within a year, and liabilities of US$2.18b falling due after that. On the other hand, it had cash of US$862.0m and US$1.37b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$1.64b.

While this might seem like a lot, it is not so bad since Weatherford International has a market capitalization of US$7.92b, and so it could probably strengthen its balance sheet by raising capital if it needed to. However, it is still worthwhile taking a close look at its ability to pay off debt.

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). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Weatherford International has net debt of just 0.57 times EBITDA, indicating that it is certainly not a reckless borrower. And this view is supported by the solid interest coverage, with EBIT coming in at 8.2 times the interest expense over the last year. In addition to that, we're happy to report that Weatherford International has boosted its EBIT by 38%, thus reducing the spectre of future debt repayments. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Weatherford International can strengthen its balance sheet over time.

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, Weatherford International recorded free cash flow worth 62% 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 Weatherford International's demonstrated ability to grow its EBIT delights us like a fluffy puppy does a toddler. And that's just the beginning of the good news since its net debt to EBITDA is also very heartening. Zooming out, Weatherford International seems to use debt quite reasonably; and that gets the nod from us. After all, sensible leverage can boost returns on equity. 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.
