Marathon Petroleum posts highest profit since 2022 as supply disruptions lift margins

Aug 4 (Reuters) – Refiner Marathon Petroleum reported its highest quarterly profit in four years on Tuesday and topped analysts’ profit estimates, as prolonged disruptions to ​crude supplies through the Strait of Hormuz lifted refining ‌margins.

Shares of Marathon rose around 2.1% in premarket trade.

Refining margins for gasoline, diesel and jet fuel soared after the effective closure of the Strait of Hormuz for months disrupted crude flows to refiners. ‌Repeated ​Iranian attacks on refineries across the ⁠Middle East further squeezed ⁠fuel supplies.

Marathon’s results follow rivals Valero Energy and HF Sinclair also reporting their highest quarterly profits since 2022.

Marathon’s quarterly refining and marketing margin doubled to $36.33 per barrel from ​a year ago.

The company’s crude capacity utilization was 94%, resulting in total throughput of 2.9 million barrels per ⁠day (bpd) for the second quarter. This ⁠compares with last year’s 97% utilization and ​total throughput of 3.1 million bpd.

Capacity utilization is a measure ​of how much of a refinery’s processing capacity is ‌being used.

For the third quarter, Marathon expects total refinery throughput of 3 million bpd.

The company’s renewable diesel unit posted adjusted core profit of $258 million in the second quarter, versus ⁠a loss of $19 million a year ago, helped by stronger margins, higher throughputs and improved regulatory credit values.

Renewable fuels, which have ⁠weighed on U.S. ‌refiners’ earnings for years, have recently become ⁠a stronger profit contributor as government biofuel ​mandates ‌boosted demand and higher diesel prices linked ​to the ⁠Middle East conflict improved margins.

The top U.S. refiner posted adjusted profit of $17.73 per share for the three months ended June 30, versus average analysts’ estimate of $13.73 per share, according to data compiled by LSEG.
