Most Popular Narrative: 1.2% Undervalued

The most widely followed narrative sets Marathon Petroleum’s fair value at $196 per share, just above the latest close of $193.76. This hints at only a slight gap between current pricing and potential worth. This valuation suggests that, while the market has recognized recent gains, there could still be a slim valuation upside.

Strong product demand and capacity reductions support high refinery utilization, improved margins, and revenue growth in supply-constrained markets. Portfolio optimization, disciplined capital allocation, and investment in renewables bolster operational flexibility, shareholder returns, and long-term resilience.

Another View: Is Multiples-Based Valuation Sending Mixed Signals?

While the fair value estimate signals Marathon Petroleum is slightly undervalued, a closer look at its price-to-earnings ratio points to a different story. The company trades at 20.2 times earnings, which is notably higher than the US Oil and Gas industry average of 13.4 and its own fair ratio of 19.5. This premium could suggest investors are already paying up for expected growth, increasing the risk if those expectations fall short. Are the market’s optimism and premium price justified by the fundamentals?
