David Iben put it well when he said, 'Volatility is not a risk we care about. What we care about is avoiding the 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. We note that Murphy USA Inc. (NYSE:MUSA) does have debt on its balance sheet. But should shareholders be worried about its use of debt?

Why Does Debt Bring Risk?

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. Ultimately, if the company can't fulfill its legal obligations to repay debt, shareholders could walk away with nothing. 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, plenty of companies use debt to fund growth, without any negative consequences. When we think about a company's use of debt, we first look at cash and debt together.

How Much Debt Does Murphy USA Carry?

The chart below, which you can click on for greater detail, shows that Murphy USA had US$1.71b in debt in September 2024; about the same as the year before. However, it does have US$54.0m in cash offsetting this, leading to net debt of about US$1.66b.

How Healthy Is Murphy USA's Balance Sheet?

The latest balance sheet data shows that Murphy USA had liabilities of US$858.8m due within a year, and liabilities of US$2.71b falling due after that. Offsetting this, it had US$54.0m in cash and US$262.6m in receivables that were due within 12 months. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$3.26b.

While this might seem like a lot, it is not so bad since Murphy USA has a huge market capitalization of US$10.2b, 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.

We measure a company's debt load relative to its earnings power by looking at its net debt divided by its earnings before interest, tax, depreciation, and amortization (EBITDA) and by calculating how easily its earnings before interest and tax (EBIT) cover its interest expense (interest cover). Thus we consider debt relative to earnings both with and without depreciation and amortization expenses.

With a debt to EBITDA ratio of 1.7, Murphy USA uses debt artfully but responsibly. And the alluring interest cover (EBIT of 8.2 times interest expense) certainly does not do anything to dispel this impression. On the other hand, Murphy USA saw its EBIT drop by 2.6% in the last twelve months. That sort of decline, if sustained, will obviously make debt harder to handle. 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 Murphy USA can strengthen its balance sheet over time.

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, Murphy USA recorded free cash flow worth 60% 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

Murphy USA's interest cover was a real positive on this analysis, as was its conversion of EBIT to free cash flow. On the other hand, its EBIT growth rate makes us a little less comfortable about its debt. When we consider all the elements mentioned above, it seems to us that Murphy USA is managing its debt quite well. Having said that, the load is sufficiently heavy that we would recommend any shareholders keep a close eye on it. 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, we've discovered 1 warning sign for Murphy USA that you should be aware of before investing here.
