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. Unlike many peers that focus on a single segment, HF Sinclair integrates multiple stages of the energy value chain—from producing and processing fuels to distributing them—while expanding into renewable and specialty product areas. 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.

HF Sinclair CEO and CFO to depart after internal review raises concerns

Sinclair Oil expects to permanently separate from CEO Tim Go and CFO Atanas Atanasov after both executives took voluntary leave last month, the company announced in its annual report. Go stepped aside after Atanasov raised concerns that certain actions by Go created an unfavorable "tone at the top" regarding Sinclair's 2025 disclosure processes. An internal review by the board with outside legal counsel concluded Go's actions did not ultimately impact disclosure processes, but developed separate concerns about his communication approach during this period. Atanasov subsequently took leave after the board raised concerns about his future working relationships with management. Chairperson Franklin Myers is temporarily covering Go's duties, whilst Vivek Garg serves as acting CFO. The leadership changes coincide with Sinclair launching a joint venture with UPOP Holdings for 30 convenience stores across Colorado and New Mexico.

HF Sinclair CFO takes voluntary leave amid audit committee concerns over disclosure processes

HF Sinclair Corporation's chief financial officer, Atanas Atanasov, has taken a voluntary leave of absence following concerns raised by the company's audit committee. The petroleum refiner has appointed Vivek Garg as interim CFO. The development follows CEO Tim Go's similar request filed on 17 February, with Board Chair Franklin Myers stepping in as interim CEO. The leadership changes stem from an assessment of the company's disclosure processes initiated in January. Atanasov had raised concerns that certain actions by Go created an unfavourable "tone at the top" regarding disclosure processes for fiscal year 2025. However, separate concerns later emerged about Atanasov's actions during the review process and his working relationships with management. HF Sinclair is negotiating separation arrangements with both executives.

HF Sinclair posts record refining throughput, receives $313M boost from EPA waivers as CEO takes voluntary leave

HF Sinclair Corporation reported record annual refining throughput of 652,000 barrels per day in 2025, though fourth-quarter results were weakened by declining fuel margins and inventory liquidation following maintenance. The company achieved an $87 million year-over-year reduction in refining operating costs through improved reliability and cost controls. CEO Timothy Go has taken voluntary leave, with Franklin Myers assuming the role of temporary CEO. An ongoing Audit Committee review of disclosure processes does not affect reported financial figures, management emphasised. For 2026, HF Sinclair expects throughput of 585,000 to 615,000 barrels per day, with sustaining capital expenditures decreasing by $125 million. The company received $313 million in EPA small refinery RINs waivers during the fourth quarter. Management expressed optimism about 2026 margins, citing global supply-demand deficits.
