Howard Marks put it nicely when he said that, rather than worrying about share price volatility, 'The possibility of permanent loss is the risk I worry about... and every practical investor I know worries about.' 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 can see that Murphy USA Inc. (NYSE:MUSA) does use debt in its business. But the more important question is: how much risk is that debt creating?

When Is Debt Dangerous?

Debt and other liabilities become risky for a business when it cannot easily fulfill those obligations, either with free cash flow or by raising capital at an attractive price. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. However, a more usual (but still expensive) situation is where a company must dilute shareholders at a cheap share price simply to get debt under control. Having said that, the most common situation is where a company manages its debt reasonably well - and to its own advantage. The first thing to do when considering how much debt a business uses is to look at its cash and debt together.

How Much Debt Does Murphy USA Carry?

As you can see below, Murphy USA had US$1.67b of debt, at March 2024, which is about the same as the year before. You can click the chart for greater detail. On the flip side, it has US$62.8m in cash leading to net debt of about US$1.61b.

How Strong Is Murphy USA's Balance Sheet?

The latest balance sheet data shows that Murphy USA had liabilities of US$884.7m due within a year, and liabilities of US$2.64b falling due after that. Offsetting these obligations, it had cash of US$62.8m as well as receivables valued at US$380.5m due within 12 months. So it has liabilities totalling US$3.08b more than its cash and near-term receivables, combined.

While this might seem like a lot, it is not so bad since Murphy USA has a market capitalization of US$9.75b, 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.

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.

Murphy USA's net debt of 1.6 times EBITDA suggests graceful use of debt. And the alluring interest cover (EBIT of 8.4 times interest expense) certainly does not do anything to dispel this impression. On the other hand, Murphy USA's EBIT dived 16%, over the last year. We think hat kind of performance, if repeated frequently, could well lead to difficulties for the stock. There's no doubt that we learn most about debt from the balance sheet. But it is future earnings, more than anything, that will determine Murphy USA's ability to maintain a healthy balance sheet going forward.

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, Murphy USA 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

Based on what we've seen Murphy USA is not finding it easy, given its EBIT growth rate, but the other factors we considered give us cause to be optimistic. In particular, we thought its interest cover was a positive. Looking at all this data makes us feel a little cautious about Murphy USA's debt levels. 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. For example - Murphy USA has 1 warning sign we think you should be aware of.
