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 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, Cleveland-Cliffs Inc. (NYSE:CLF) does carry debt. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

Debt is a tool to help businesses grow, but if a business is incapable of paying off its lenders, then it exists at their mercy. 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. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Cleveland-Cliffs's Net Debt?

As you can see below, Cleveland-Cliffs had US$3.53b of debt at June 2024, down from US$3.99b a year prior. However, it also had US$110.0m in cash, and so its net debt is US$3.42b.

How Healthy Is Cleveland-Cliffs' Balance Sheet?

We can see from the most recent balance sheet that Cleveland-Cliffs had liabilities of US$3.32b falling due within a year, and liabilities of US$6.24b due beyond that. On the other hand, it had cash of US$110.0m and US$1.77b worth of receivables due within a year. So its liabilities total US$7.67b more than the combination of its cash and short-term receivables.

When you consider that this deficiency exceeds the company's US$5.57b market capitalization, you might well be inclined to review the balance sheet intently. Hypothetically, extremely heavy dilution would be required if the company were forced to pay down its liabilities by raising capital at the current share price.

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

Cleveland-Cliffs has net debt worth 2.1 times EBITDA, which isn't too much, but its interest cover looks a bit on the low side, with EBIT at only 2.6 times the interest expense. 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. We saw Cleveland-Cliffs grow its EBIT by 4.0% in the last twelve months. Whilst that hardly knocks our socks off it is a positive when it comes to debt. 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 Cleveland-Cliffs can strengthen its balance sheet over time. So if you want to see what the professionals think, you might find this free report on analyst profit forecasts to be interesting.

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. Over the last three years, Cleveland-Cliffs recorded free cash flow worth a fulsome 89% of its EBIT, which is stronger than we'd usually expect. That positions it well to pay down debt if desirable to do so.

Our View

Cleveland-Cliffs's level of total liabilities and interest cover definitely weigh on it, in our esteem. But the good news is it seems to be able to convert EBIT to free cash flow with ease. When we consider all the factors discussed, it seems to us that Cleveland-Cliffs is taking some risks with its use of debt. So while that leverage does boost returns on equity, we wouldn't really want to see it increase from here. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately, every company can contain risks that exist outside of the balance sheet. We've identified 3 warning signs with Cleveland-Cliffs (at least 1 which shouldn't be ignored) , and understanding them should be part of your investment process.
