See our latest analysis for Marathon Petroleum.

At a share price of US$172.01, Marathon Petroleum’s recent 5.1% 1 month share price return contrasts with a 12.1% 3 month share price decline. Its 16.1% 1 year total shareholder return and 314.5% 5 year total shareholder return point to stronger longer term momentum than the shorter term swings suggest.

If you are weighing Marathon Petroleum alongside other opportunities, this can be a good moment to broaden your search with aerospace and defense stocks as another sector to consider.

With a value score of 4, an indicated intrinsic discount of 62.2% and a price of US$172.01 versus a US$194.83 analyst target, you have to ask: is there genuine upside here, or is the market already pricing in future growth?

Against the last close of $172.01, the most followed narrative sees fair value around $194.61, built on detailed assumptions about future earnings and margins.

Disciplined capital allocation through continued share buybacks, increasing MPLX distributions, and maintenance of an investment-grade balance sheet are set to drive higher earnings per share and sustained shareholder returns, aligning with positive long-term company trends.

The fair value of $194.61 leans on earnings and cash flow assumptions, but the current P/E of 18x adds a different twist. It looks expensive versus the US Oil and Gas industry at 13.6x, yet cheaper than peers at 31.8x and below a fair ratio of 21x. Is that a cushion or a value trap if expectations reset?
