Morgan Stanley Sees Marathon Petroleum (MPC) Breaking into New Highs

Marathon Petroleum Corporation (NYSE:MPC) has substantially outperformed the wider market this year, supported by an unusually sharp surge in global refining margins as the prolonged Iran crisis has significantly tightened global refining capacity and reduced supplies of gasoline, diesel, and jet fuel.

With Marathon up by over 150% since the beginning of 2026, there are now concerns that the stock may have topped out. However, the analysts over at Morgan Stanley are convinced that the rally still has further room to run. On September 14, Morgan Stanley analyst Joe Laetsch significantly raised the firm's price target on MPC from $265 to $453, while reaffirming an 'Overweight' rating on the shares.

The target boost reflects an upside of over 9% from the current price level and even exceeds the stock's record high of just under $411 per share achieved earlier this month. The Morgan Stanley update comes amid broader Wall Street optimism surrounding the American refining giant, with analysts from Raymon James, UBS, and several others also improving their respective outlooks on MPC.

Cashing In on the Refining Crunch:

Morgan Stanley's vote of confidence suggests that Wall Street expects the ongoing refining upcycle to last longer than previously expected, especially given the fresh wave of attacks between Washington and Tehran. Even if the conflict in the Middle East subsides, the region's refined fuel output is expected to remain relatively tight, since the damaged or idled refineries in the Middle East are likely to take some time to return to full operations.

As the largest refiner by volume in the United States, Marathon has significant operating leverage to capitalize on the current high-margin environment. The company already demonstrated its ability to translate the high crack spreads into material earnings when it delivered an almost fourfold increase in profits in the second quarter.

Another major growth engine for Marathon is its stake in MPLX, which owns and operates midstream energy infrastructure. This provides the American refiner with significant exposure to a diversified midstream infrastructure business with relatively stable fee-based income, helping it offset the cyclicality of the refining business.

Marathon Petroleum's shareholder return strategy also adds to its investment case. The company utilized its elevated cash flows to return $2.8 billion to shareholders during Q2, up from $1 billion in the year-ago period. According to TD Cowen's Jason Gabelman, the refiner is expected to repurchase about 20% of its market value between Q3 and the end of next year, potentially lifting its per-share earnings.
