3. Governance and Board Representation Implications

Under the Stockholders Agreement dated August 2, 2021:

• Designation Threshold: The REH Parties hold the right to designate one individual for election or appointment to HF Sinclair's Board as long as they beneficially own between 5% and 15% of outstanding common stock.
• Ownership Shift: Prior to this transaction, REH held 8,881,662 shares (~5.0%). After selling 2,350,000 shares, REH's holdings drop to 6,531,662 shares, falling below the 5% threshold.
• Board Seat Impact: If REH remains below the 5% Designation Threshold on January 13, 2027, the REH Board designee must tender an offer of resignation within 30 days. The Board will maintain sole discretion to accept or reject the resignation.

4. Market & Trading Implications

• Significance: High. A $257M single-block repurchase removes substantial secondary market overhang that could otherwise occur through open-market sales by a legacy corporate sponsor.
• EPS Accretion: Reducing the share count by 2.35 million shares provides an immediate, non-dilutive EPS tailwind.
