The termination of the CFO after a prolonged leave, combined with the prior day's disclosure of a large CEO severance and the proximity to the annual meeting, signals deep leadership instability. Traders should watch for a permanent CFO appointment and any further management departures. The lack of a permanent CFO raises execution risk on capital allocation and financial reporting.
Price Chart
Executive Summary
HF Sinclair terminated CFO Atanas Atanasov effective immediately on May 13, 2026, converting his prior leave into a formal termination. He will receive severance under the company's Severance Pay Plan if conditions are met. Acting CFO Vivek Garg (Chief Accounting Officer) remains in place, but the permanent CFO vacancy and the prior day's disclosure of a $4.735M cash severance for the former CEO create a leadership vacuum one day after the annual shareholder vote.
