Does Rio Tinto Group (LON:RIO) Have A Healthy Balance Sheet?

Some say volatility, rather than debt, is the best way to think about risk as an investor, but Warren Buffett famously said that 'Volatility is far from synonymous with risk.' 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, Rio Tinto Group (LON:RIO) does carry debt. But is this debt a concern to shareholders?

What Risk Does Debt Bring?

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. Part and parcel of capitalism is the process of 'creative destruction' where failed businesses are mercilessly liquidated by their bankers. 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, plenty of companies use debt to fund growth, without any negative consequences. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

What Is Rio Tinto Group's Debt?

You can click the graphic below for the historical numbers, but it shows that as of December 2023 Rio Tinto Group had US$13.0b of debt, an increase on US$11.1b, over one year. On the flip side, it has US$10.8b in cash leading to net debt of about US$2.25b.

How Strong Is Rio Tinto Group's Balance Sheet?

The latest balance sheet data shows that Rio Tinto Group had liabilities of US$12.7b due within a year, and liabilities of US$34.5b falling due after that. Offsetting these obligations, it had cash of US$10.8b as well as receivables valued at US$3.47b due within 12 months. So its liabilities total US$33.0b more than the combination of its cash and short-term receivables.

This deficit isn't so bad because Rio Tinto Group is worth a massive US$114.3b, and thus could probably raise enough capital to shore up its balance sheet, if the need arose. However, it is still worthwhile taking a close look at its ability to pay off debt.

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.

Rio Tinto Group's net debt is only 0.12 times its EBITDA. And its EBIT covers its interest expense a whopping 15.2 times over. So you could argue it is no more threatened by its debt than an elephant is by a mouse. On the other hand, Rio Tinto Group's EBIT dived 18%, over the last year. We think hat kind of performance, if repeated frequently, could well lead to difficulties for the stock. 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 Rio Tinto Group can strengthen its balance sheet over time.

Finally, a business needs free cash flow to pay off debt; accounting profits just don't cut it. So the logical step is to look at the proportion of that EBIT that is matched by actual free cash flow. Over the most recent three years, Rio Tinto Group recorded free cash flow worth 57% 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

Both Rio Tinto Group's ability to to cover its interest expense with its EBIT and its net debt to EBITDA gave us comfort that it can handle its debt. In contrast, our confidence was undermined by its apparent struggle to grow its EBIT. When we consider all the factors mentioned above, we do feel a bit cautious about Rio Tinto Group's use of debt. While we appreciate debt can enhance returns on equity, we'd suggest that shareholders keep close watch on its debt levels, lest they increase. 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.
