The simultaneous departure of CEO and absence of CFO creates a leadership vacuum at a $13B company, likely weighing on the stock near-term. Watch for the outcome of the May 13 annual meeting and any announcement of a permanent CEO or CFO replacement. The activist context (cross-filing amplifiers) suggests heightened odds of board changes or strategic review.

Executive Summary
HF Sinclair filed a DEFA14A supplementing its proxy statement for the May 13, 2026 annual meeting, formalizing the separation of former CEO Timothy Go with a $4.735M cash severance and partial equity vesting. The filing also discloses that CFO Atanas Atanasov remains on leave with no separation agreement reached, creating ongoing leadership uncertainty one day before the shareholder vote.
Key Facts
- Former CEO Timothy Go's employment ended May 11, 2026; he receives $4,735,000 cash severance in 12 monthly installments.
- Go forfeits most equity: only 29,616 of 129,880 RSUs vest; 163,609 of 349,808 PSUs conditionally vest (time-based only, performance criteria remain).
- CFO Atanas Atanasov remains on leave since Feb 24, 2026; no separation agreement reached and no assurance one will be reached.
- Annual meeting is May 13, 2026 — one day after this filing; proposals and board recommendations unchanged.
- Cross-filing context: 8-K filed same day (May 12) formalizing Go's separation; prior proxy fight materials suggest activist pressure.
Financial Impact
$4.735M cash severance plus partial equity vesting; no material impact on $13.1B market cap but leadership vacuum is significant
Risk Factors
- Prolonged leadership uncertainty with both CEO and CFO roles unfilled
- Activist pressure may escalate if no permanent CEO named soon
- Potential for further management departures or operational disruption
