## About

HollyFrontier Corporation (now HF Sinclair Corporation) was formed through the 2004 merger of Holly Corporation and Frontier Oil Corporation, creating one of the largest independent refiners in the U.S. Mid-Continent region. The company is publicly traded and operates as a traditional petroleum refining business, not as a family office or asset manager. Its strategy involves crude oil processing at six refineries in Kansas, Oklahoma, New Mexico, Utah, Montana, and Wyoming. The refining operations produce gasoline, diesel, jet fuel, asphalt, and specialty lubricants. In March 2021, HF Sinclair acquired the Sinclair-branded retail network of 1,200 convenience stores and related logistics assets for roughly $1.28 billion, expanding downstream integration (per the firm, March 2021). The company also operates renewable diesel plants in Wyoming and Nevada. HF Sinclair employs approximately 3,800 people and maintains corporate offices in Dallas, with additional operational centers in Tulsa and Salt Lake City. The company's revenues exceed $30 billion annually, though firm-level AUM figures are not publicly disclosed as it is a publicly traded corporation rather than a private asset manager. No philanthropic or investment vehicle structures are separately reported. The key structural differentiator is HF Sinclair's status as a publicly held corporation with no single controlling family — it lacks the private ownership architecture typical of family offices. Its regulatory filings with the SEC replace the confidential governance structures common in private firms.
