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 seems the smart money knows that debt - which is usually involved in bankruptcies - is a very important factor, when you assess how risky a company is. As with many other companies Murphy USA Inc. (NYSE:MUSA) makes use of debt. But the more important question is: how much risk is that debt creating?
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. 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 examine debt levels, we first consider both cash and debt levels, together.
The image below, which you can click on for greater detail, shows that at September 2025 Murphy USA had debt of US$2.13b, up from US$1.71b in one year. However, it does have US$42.8m in cash offsetting this, leading to net debt of about US$2.08b.
According to the last reported balance sheet, Murphy USA had liabilities of US$940.2m due within 12 months, and liabilities of US$3.19b due beyond 12 months. On the other hand, it had cash of US$42.8m and US$304.1m worth of receivables due within a year. So its liabilities total US$3.78b more than the combination of its cash and short-term receivables.
Murphy USA has a market capitalization of US$7.80b, so it could very likely raise cash to ameliorate its balance sheet, if the need arose. But we definitely want to keep our eyes open to indications that its debt is bringing too much risk.

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.
With a debt to EBITDA ratio of 2.1, Murphy USA uses debt artfully but responsibly. And the alluring interest cover (EBIT of 7.2 times interest expense) certainly does not do anything to dispel this impression. Unfortunately, Murphy USA saw its EBIT slide 4.0% in the last twelve months. If that earnings trend continues then its debt load will grow heavy like the heart of a polar bear watching its sole cub. When analysing debt levels, the balance sheet is the obvious place to start. But ultimately the future profitability of the business will decide if Murphy USA 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 clearly need to look at whether that EBIT is leading to corresponding free cash flow. During the last three years, Murphy USA produced sturdy free cash flow equating to 54% of its EBIT, about what we'd expect. This cold hard cash means it can reduce its debt when it wants to.
Even if we have reservations about how easily Murphy USA is capable of (not) growing its EBIT, its interest cover and conversion of EBIT to free cash flow make us think feel relatively unconcerned. We think that Murphy USA's debt does make it a bit risky, after considering the aforementioned data points together. That's not necessarily a bad thing, since leverage can boost returns on equity, but it is something to be aware of. The balance sheet is clearly the area to focus on when you are analysing debt. However, not all investment risk resides within the balance sheet - far from it. These risks can be hard to spot. Every company has them, and we've spotted 2 warning signs for Murphy USA you should know about.
