Marathon Petroleum Crushed Q1 Estimates, Then the Ceasefire Arrived

Marathon Petroleum Corporation (MPC), the largest U.S. refiner by volume with around 3 million barrels per day of crude throughput capacity, reported first-quarter 2026 adjusted EPS of $1.65 against a Wall Street consensus of $0.75.

Net income came in at $511 million.

The gap between what analysts expected and what MPC delivered reflected a crack spread environment that widened sharply after U.S.-Israeli strikes disrupted Middle Eastern refining capacity and nearly closed the Strait of Hormuz, a chokepoint carrying roughly a fifth of global oil consumption.

Marathon’s refining and marketing margin reached $17.74 per barrel in Q1, up from $13.38 per barrel a year earlier.

The company ran its refineries at 89% utilization across all three regions (Gulf Coast, Mid-Continent, and West Coast) and completed roughly 40% of its full-year planned turnaround activity in the quarter, pulling maintenance forward to position for a stronger second half.

CEO Maryann Mannen explained the rationale directly on Q1 earnings call: “This was just our intent to bring that cost forward so that we are prepared, as we are running strong in the second quarter, given the demand that we’re seeing.”

Marathon also doubled its Canadian crude volumes on the U.S. Gulf Coast, purchased approximately 10 million barrels from the Strategic Petroleum Reserve at advantaged prices, and moved jet fuel from the Gulf Coast to Alaska and ULSD to Australia under Jones Act waiver arrangements, both firsts for the company.

The Garyville jet flexibility project came online in March, adding more than 30,000 barrels per day of incremental jet production capacity at one of the most competitive refineries in the world.

On top of the operational beat, MPC announced an additional $5 billion share repurchase authorization, bringing total remaining buyback capacity to approximately $9 billion.

Then the ceasefire came.

U.S. and Iranian negotiators signed a memorandum of understanding on June 15, reopening the Strait of Hormuz and ending the naval blockade of Iranian ports, sending WTI crude down roughly 4% and MPC shares down between 5% and 6% on the day.

MPC Analysts Hold Conviction, but the Target Spread Tells the Real Story

Of the 18 analysts covering Marathon Petroleum stock, 6 rate it a Buy, 4 an Outperform, 7 a Hold, 1 an Underperform, and 1 a Sell, with a mean price target of around $268 and a high target of $344.

The $268 mean implies roughly 10% upside from the current price of $243, a gap narrow enough to tell you the Street sees Marathon Petroleum stock as fairly valued rather than a re-rating opportunity.

Q2 2026 EBITDA consensus sits at 6.27 billion, up 91% from 3.29 billion in Q2 2025, a level that reflects the full benefit of the elevated crack spread environment Marathon’s CEO described on the Q1 call.

Q3 2026 EBITDA is estimated at 5.42 billion and Q4 2026 at 4.27 billion, a sequential step-down that already prices in margin compression as the Strait of Hormuz reopens and Middle Eastern refining capacity gradually returns.

Management guided Q2 utilization at 94%, up from 89% in Q1, supported by the front-loaded turnaround schedule that cleared roughly 40% of full-year maintenance in Q1 to run clean through the peak demand period.

Q2 2026 FCF is estimated at 4.08 billion against 0.21 billion in Q1, a swing driven by the unwind of the working capital build and the derivative losses management flagged as timing-related on the earnings call.

The 7 Holds on the Street share one concern — if the ceasefire holds and Iranian supply normalizes faster than the deceleration already priced into Q3 and Q4, even the step-down estimates could prove too optimistic, leaving Marathon Petroleum stock with limited multiple expansion room from current levels.

With the $268 mean target sitting just 10% above the current price and the near-term EBITDA peak now visible, Marathon Petroleum stock is fairly valued.

Is Marathon Petroleum Stock Fairly Valued After the Iran Ceasefire?

TIKR’s mid-case values Marathon Petroleum at approximately $235 by December 2030, implying a negative total return of roughly 3% from the current price of $243, or roughly negative 1% annualized over the next 4.5 years.

The model’s mid-case depends on the same crack spread deceleration the Street has already priced into Q3 and Q4, with EBITDA stepping down from 6.27 billion in Q2 to 5.42 billion in Q3 and 4.27 billion in Q4 as the Hormuz reopening allows global refining capacity to gradually return.

The Q1 front-loaded turnaround strategy, which cleared roughly 40% of full-year maintenance to position for a clean Q2 and Q3 run, supports the near-term earnings trajectory the model depends on, but does not change the longer-term direction — normalization is already in the estimates.

Marathon Petroleum stock at $243 is priced above TIKR’s mid-case target of $235, which means the current price requires the favorable refining environment to persist beyond what consensus has modeled, a condition the Iran ceasefire has just made harder to defend.
