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.' 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 note that Southern Copper Corporation (NYSE:SCCO) does have debt on its balance sheet. But is this debt a concern to shareholders?

When Is Debt Dangerous?

Generally speaking, debt only becomes a real problem when a company can't easily pay it off, either by raising capital or with its own cash flow. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. However, a more common (but still painful) scenario is that it has to raise new equity capital at a low price, thus permanently diluting shareholders. Of course, debt can be an important tool in businesses, particularly capital heavy businesses. When we examine debt levels, we first consider both cash and debt levels, together.

What Is Southern Copper's Net Debt?

The chart below, which you can click on for greater detail, shows that Southern Copper had US$6.26b in debt in March 2024; about the same as the year before. However, because it has a cash reserve of US$1.58b, its net debt is less, at about US$4.67b.

How Healthy Is Southern Copper's Balance Sheet?

We can see from the most recent balance sheet that Southern Copper had liabilities of US$1.34b falling due within a year, and liabilities of US$7.84b due beyond that. Offsetting this, it had US$1.58b in cash and US$1.40b in receivables that were due within 12 months. So it has liabilities totalling US$6.21b more than its cash and near-term receivables, combined.

Given Southern Copper has a humongous market capitalization of US$84.2b, it's hard to believe these liabilities pose much threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

We use two main ratios to inform us about debt levels relative to earnings. The first is net debt divided by earnings before interest, tax, depreciation, and amortization (EBITDA), while the second is how many times its earnings before interest and tax (EBIT) covers its interest expense (or its interest cover, for short). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

Southern Copper has a low net debt to EBITDA ratio of only 0.96. And its EBIT easily covers its interest expense, being 17.4 times the size. So you could argue it is no more threatened by its debt than an elephant is by a mouse. On the other hand, Southern Copper saw its EBIT drop by 6.7% in the last twelve months. If earnings continue to decline at that rate the company may have increasing difficulty managing its debt load. The balance sheet is clearly the area to focus on when you are analysing debt. But ultimately the future profitability of the business will decide if Southern Copper 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 company can only pay off debt with cold hard cash, not accounting profits. So we always check how much of that EBIT is translated into free cash flow. Over the most recent three years, Southern Copper recorded free cash flow worth 53% 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 Southern Copper's demonstrated ability to cover its interest expense with its EBIT delights us like a fluffy puppy does a toddler. But truth be told we feel its EBIT growth rate does undermine this impression a bit. Looking at all the aforementioned factors together, it strikes us that Southern Copper can handle its debt fairly comfortably. On the plus side, this leverage can boost shareholder returns, but the potential downside is more risk of loss, so it's worth monitoring the balance sheet. 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. For example Southern Copper has 2 warning signs (and 1 which is significant) we think you should know about.
