Is Antofagasta (LON:ANTO) A Risky Investment?

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, Antofagasta plc (LON:ANTO) does carry debt. But the real question is whether this debt is making the company risky.

When Is Debt A Problem?

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. If things get really bad, the lenders can take control of the business. 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. 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.

How Much Debt Does Antofagasta Carry?

As you can see below, Antofagasta had US$3.05b of debt at June 2023, down from US$3.25b a year prior. However, it also had US$2.35b in cash, and so its net debt is US$696.5m.

A Look At Antofagasta's Liabilities

According to the last reported balance sheet, Antofagasta had liabilities of US$1.65b due within 12 months, and liabilities of US$4.70b due beyond 12 months. Offsetting these obligations, it had cash of US$2.35b as well as receivables valued at US$1.24b due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$2.76b.

Since publicly traded Antofagasta shares are worth a very impressive total of US$17.2b, it seems unlikely that this level of liabilities would be a major threat. Having said that, it's clear that we should continue to monitor its balance sheet, lest it change for the worse.

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.

Antofagasta has a low debt to EBITDA ratio of only 0.24. But the really cool thing is that it actually managed to receive more interest than it paid, over the last year. So it's fair to say it can handle debt like a hotshot teppanyaki chef handles cooking. The modesty of its debt load may become crucial for Antofagasta if management cannot prevent a repeat of the 23% cut to EBIT over the last year. When it comes to paying off debt, falling earnings are no more useful than sugary sodas are for your health. 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 Antofagasta can strengthen its balance sheet over time.

Finally, a company can only pay off debt with cold hard cash, not accounting profits. So we clearly need to look at whether that EBIT is leading to corresponding free cash flow. In the last three years, Antofagasta's free cash flow amounted to 35% of its EBIT, less than we'd expect. That's not great, when it comes to paying down debt.

Our View

Antofagasta's EBIT growth rate was a real negative on this analysis, although the other factors we considered were considerably better. There's no doubt that its ability to to cover its interest expense with its EBIT is pretty flash. Looking at all this data makes us feel a little cautious about Antofagasta's debt levels. While debt does have its upside in higher potential returns, we think shareholders should definitely consider how debt levels might make the stock more risky. There's no doubt that we learn most about debt from the balance sheet. However, not all investment risk resides within the balance sheet - far from it. For example Antofagasta has 3 warning signs (and 1 which can't be ignored) we think you should know about.
