Additional SEC filing notes

Filing notes and footnotes

Explanation of responses 2 footnotes

Footnote F1

Due to an administrative error, the reporting person filed a Form 4 which reported a grant of 56,616 Restricted Stock Unit awards ("RSUs") granted pursuant to the HF Sinclair Corporation Amended and Restated 2020 Long Term Incentive Plan ("LTIP"). This amendment is intended to report that the reporting person received a grant of 63,615 RSUs on the original transaction date.

Footnote F2

Restricted stock units granted under the LTIP. The restricted stock units vest in three equal annual installments beginning December 1, 2026 (or on the first business day thereafter if such date falls on a weekend), provided that the reporting person remains in the employ of the Issuer from the grant date through each such vesting date. The vested restricted stock units will be paid within 30 days following the vesting date in the form of the Issuer's common stock equal to the number of vested restricted stock units.
