HF Sinclair Business Summary

HF Sinclair Corporation (DINO) is an integrated independent energy company that generates revenue through the production and marketing of light refined products, renewable fuels, and specialty lubricants. The company operates through five primary business segments: Refining, which processes crude oil into gasoline and diesel; Renewables, focused on renewable diesel production; Marketing, which manages branded fuel sales under the Sinclair brand; Lubricants & Specialties, comprising the Petro-Canada Lubricants and Sonneborn businesses; and Midstream, which provides logistics and storage services. HF Sinclair distinguishes itself in the market through its high-margin specialty chemicals portfolio and a dominant regional footprint across the Rocky Mountains and Southwest U.S. It competes directly with major independent refiners such as Marathon Petroleum (MPC), Valero Energy (VLO), Phillips 66 (PSX), and PBF Energy (PBF), maintaining a competitive position as a mid-cap player with a specialized focus on niche lubricant markets and regional supply advantages. Following the 2022 merger of HollyFrontier and Sinclair Oil, the company is currently led by Franklin Myers, who was appointed as temporary Chief Executive Officer and President in February 2026 after former CEO Tim Go took a voluntary leave of absence. Myers, a veteran energy executive, previously served as the company’s Chairperson and held senior roles at Cameron International and Baker Hughes. The executive team includes Atanas H. Atanasov as Executive Vice President and Chief Financial Officer, Steven C. Ledbetter as EVP of Commercial, and Valerie Pompa as EVP of Operations. The company’s board features experienced directors such as Anna Catalano and Anne-Marie Ainsworth, while its institutional ownership is anchored by major investors including BlackRock, Vanguard, and the Holding family, the latter of whom remains the largest individual shareholder following the Sinclair acquisition.
