About the Company

HF Sinclair

Refines petroleum; markets fuels and lubricants

HF Sinclair is an independent energy company with operations across refining, midstream, and marketing, plus involvement in renewable diesel, specialty lubricants, asphalt, and chemicals. It refines crude oil into light products such as gasoline, diesel, and jet fuel, and also produces renewable diesel and other specialty products for commercial and industrial customers. Its five-area structure covers downstream refining, midstream logistics, and marketing to a diverse customer base, with additional international activity in Canada and the Netherlands.

The company aims to grow its footprint across the energy value chain, broaden its product slate (including renewables and chemicals), and strengthen its presence in North American and international markets.
