Marathon Petroleum (NYSE:MPC) Seems To Use Debt Quite Sensibly

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.' It's only natural to consider a company's balance sheet when you examine how risky it is, since debt is often involved when a business collapses. We note that Marathon Petroleum Corporation (NYSE:MPC) does have debt on its balance sheet. But is this debt a concern to shareholders?

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. In the worst case scenario, a company can go bankrupt if it cannot pay its creditors. 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. By replacing dilution, though, debt can be an extremely good tool for businesses that need capital to invest in growth at high rates of return. The first step when considering a company's debt levels is to consider its cash and debt together.

What Is Marathon Petroleum's Net Debt?

As you can see below, Marathon Petroleum had US$26.8b of debt, at June 2023, which is about the same as the year before. You can click the chart for greater detail. However, it does have US$11.5b in cash offsetting this, leading to net debt of about US$15.3b.

How Healthy Is Marathon Petroleum's Balance Sheet?

The latest balance sheet data shows that Marathon Petroleum had liabilities of US$17.5b due within a year, and liabilities of US$36.4b falling due after that. On the other hand, it had cash of US$11.5b and US$10.3b worth of receivables due within a year. So its liabilities outweigh the sum of its cash and (near-term) receivables by US$32.1b.

While this might seem like a lot, it is not so bad since Marathon Petroleum has a huge market capitalization of US$61.7b, 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.

Marathon Petroleum has a low net debt to EBITDA ratio of only 0.75. And its EBIT easily covers its interest expense, being 20.7 times the size. So we're pretty relaxed about its super-conservative use of debt. On top of that, Marathon Petroleum grew its EBIT by 33% over the last twelve months, and that growth will make it easier to handle its debt. When analysing debt levels, the balance sheet is the obvious place to start. But it is future earnings, more than anything, that will determine Marathon Petroleum's ability to maintain a healthy balance sheet going forward. 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 business needs free cash flow to pay off debt; accounting profits just don't cut it. So we always check how much of that EBIT is translated into free cash flow. Over the last three years, Marathon Petroleum recorded free cash flow worth a fulsome 83% of its EBIT, which is stronger than we'd usually expect. That positions it well to pay down debt if desirable to do so.

Our View

The good news is that Marathon Petroleum's demonstrated ability to cover its interest expense with its EBIT delights us like a fluffy puppy does a toddler. But, on a more sombre note, we are a little concerned by its level of total liabilities. Looking at the bigger picture, we think Marathon Petroleum's use of debt seems quite reasonable and we're not concerned about it. After all, sensible leverage can boost returns on equity. 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.
