Can Marathon Petroleum Corporation's (NYSE:MPC) ROE Continue To Surpass The Industry Average?
Many investors are still learning about the various metrics that can be useful when analysing a stock. This article is for those who would like to learn about Return On Equity (ROE). To keep the lesson grounded in practicality, we’ll use ROE to better understand Marathon Petroleum Corporation (NYSE:MPC).
Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors’ money. Put another way, it reveals the company’s success at turning shareholder investments into profits.
The formula for ROE is:
Return on Equity = Net Profit (from continuing operations) ÷ Shareholders’ Equity
So, based on the above formula, the ROE for Marathon Petroleum is:
16% = US$3.8b ÷ US$23b (Based on the trailing twelve months to June 2025).
The ‘return’ is the income the business earned over the last year. That means that for every $1 worth of shareholders’ equity, the company generated $0.16 in profit.

One simple way to determine if a company has a good return on equity is to compare it to the average for its industry. The limitation of this approach is that some companies are quite different from others, even within the same industry classification. As is clear from the image below, Marathon Petroleum has a better ROE than the average (11%) in the Oil and Gas industry.
That’s what we like to see. Bear in mind, a high ROE doesn’t always mean superior financial performance. A higher proportion of debt in a company’s capital structure may also result in a high ROE, where the high debt levels could be a huge risk .

Most companies need money — from somewhere — to grow their profits. That cash can come from issuing shares, retained earnings, or debt. In the case of the first and second options, the ROE will reflect this use of cash, for growth. In the latter case, the debt required for growth will boost returns, but will not impact the shareholders’ equity. In this manner the use of debt will boost ROE, even though the core economics of the business stay the same.
It’s worth noting the high use of debt by Marathon Petroleum, leading to its debt to equity ratio of 1.20. While its ROE is respectable, it is worth keeping in mind that there is usually a limit as to how much debt a company can use. Investors should think carefully about how a company might perform if it was unable to borrow so easily, because credit markets do change over time.
Return on equity is useful for comparing the quality of different businesses. In our books, the highest quality companies have high return on equity, despite low debt. If two companies have the same ROE, then I would generally prefer the one with less debt.
But when a business is high quality, the market often bids it up to a price that reflects this. The rate at which profits are likely to grow, relative to the expectations of profit growth reflected in the current price, must be considered, too. So I think it may be worth checking this free report on analyst forecasts for the company.
But note: Marathon Petroleum may not be the best stock to buy. So take a peek at this free list of interesting companies with high ROE and low debt.
