HF Sinclair Corporation (NYSE:DINO) is an independent petroleum refiner in the United States with operations throughout the mid-continent, southwestern, and Rocky Mountain regions.

HF Sinclair Corporation (NYSE:DINO) revealed on February 27 that its Chief Financial Officer, Atanas Atanasov, had taken a voluntary leave of absence amid concerns raised by its audit committee. The development comes following reports on February 17 that the company’s board member and CEO, Tim Go, had filed a similar request, with Board Chair Franklin Myers stepping in as the interim CEO.

The shakeup in top leadership comes after the petroleum refiner initiated an assessment of matters relating to its disclosure process in January, with Atanasov raising concerns that certain actions taken by Tim Go created an unfavorable ‘tone at the top’ related to the disclosure processes of FY 2025.

HF Sinclair Corporation (NYSE:DINO) stated the following in its 10-K filing on February 27:

“During the latter stages of this review, a separate concern developed relating to certain actions taken by Mr. Atanasov bearing upon the review process… and the viability of his future working relationships with other members of the company’s management team. After discussion of these concerns, on February 24, 2026, the board of directors received a request from Mr. Atanasov to take a voluntary leave of absence from his duties.”

HF Sinclair Corporation (NYSE:DINO) has named Vivek Garg as its interim CFO, and the company is working to negotiate a mutually agreeable separation arrangement with both Go and Atanasov.
