Share performance of US refiners so far this year

U.S. refined ​products exports hit a record high in March as the Iran war ​and the near-closure of the Strait of Hormuz tightened global fuel ⁠supplies, forcing output cuts abroad and supporting margins for U.S. refiners, which ​are less reliant on Middle Eastern crude and are well placed to capture demand ​through exports.

Marathon Petroleum, the top U.S. refiner by volume, said refining and marketing margin was $17.74 per barrel for the first quarter, 32.6% higher than last year.

The strong margins have lifted results ​across the sector, with Valero Energy (VLO.N), Phillips 66 (PSX.N) and HF Sinclair (DINO.N) all reporting ​profits that exceeded expectations.

U.S. Gulf Coast refiners are reaping their strongest margins in years, with disruptions to Middle Eastern oil flows from the Iran war driving demand for U.S. fuel exports.

Marathon reported crude capacity utilization of 89%, resulting in total throughput of ‌2.9 ⁠million barrels per day (bpd) in the first quarter, compared with 2.8 million bpd a year earlier.

For the second quarter, Marathon expects throughput of 2.99 million bpd.

First-quarter results were partly offset by higher operating costs linked to refinery turnaround activity and derivative losses tied ​to economic hedging.

It ​expects to spend $1.5 ⁠billion in 2026, largely on projects to improve margins at key refineries.

In the first quarter, Marathon brought its Garyville jet ​flexibility project online, enabling it to upgrade existing output into ​higher-value jet ⁠fuel and capture rising domestic and export demand.

The Findlay, Ohio-based refiner reported adjusted profit of $1.65 per share for the quarter ended March 31, beating analysts’ average estimate of ⁠75 ​cents per share, according to data compiled by ​LSEG.
