TheStreet Ratings team rates MARATHON PETROLEUM CORP as a Buy with a ratings score of B+. TheStreet Ratings Team has this to say about their recommendation:

"We rate MARATHON PETROLEUM CORP (MPC) a BUY. This is driven by multiple strengths, which we believe should have a greater impact than any weaknesses, and should give investors a better performance opportunity than most stocks we cover. The company's strengths can be seen in multiple areas, such as its revenue growth, solid stock price performance, attractive valuation levels, good cash flow from operations and increase in net income. We feel these strengths outweigh the fact that the company has had somewhat disappointing return on equity."

Highlights from the analysis by TheStreet Ratings Team goes as follows:

  • MPC's revenue growth has slightly outpaced the industry average of 3.0%. Since the same quarter one year prior, revenues slightly increased by 4.8%. Growth in the company's revenue appears to have helped boost the earnings per share.
  • Looking at where the stock is today compared to one year ago, we find that it is not only higher, but it has also clearly outperformed the rise in the S&P 500 over the same period. Although other factors naturally played a role, the company's strong earnings growth was key. Turning our attention to the future direction of the stock, it goes without saying that even the best stocks can fall in an overall down market. However, in any other environment, this stock still has good upside potential despite the fact that it has already risen in the past year.
  • The net income growth from the same quarter one year ago has significantly exceeded that of the S&P 500 and the Oil, Gas & Consumable Fuels industry. The net income increased by 44.2% when compared to the same quarter one year prior, rising from $593.00 million to $855.00 million.
  • Net operating cash flow has significantly increased by 301.37% to $878.00 million when compared to the same quarter last year. In addition, MARATHON PETROLEUM CORP has also vastly surpassed the industry average cash flow growth rate of -5.04%.
