HF Sinclair Corp 8-K

What Happened
HF Sinclair Corporation announced that Timothy Go, its Chief Executive Officer and President, left the company effective May 11, 2026 pursuant to a Separation and Release Agreement. Mr. Go also resigned from the Board. Franklin Myers, the Board Chair, had been serving as interim CEO since February 17, 2026. The parties exchanged mutual releases and Mr. Go agreed to continue to abide by confidentiality, non‑competition and non‑solicitation obligations.

Key Details

• Separation payment: $4,735,000 to be paid in 12 substantially equal monthly installments beginning on May 11, 2026.
• Benefits: If timely elected, COBRA continuation of group health plan coverage at active employee rates for 12 months after the separation date.
• Equity: As of the separation, Mr. Go held 129,880 RSUs and 349,808 PSUs; the agreement provides for vesting/settlement of 29,616 RSUs and conditional time‑based vesting of 163,609 PSUs (PSUs remain subject to original performance criteria).
• Conditions: Severance and partial equity vesting are subject to Mr. Go’s compliance with continuing obligations and not revoking the general release.

Why It Matters
This filing confirms a permanent leadership change at HF Sinclair with the CEO role effectively transitioned to interim leadership (Board Chair Franklin Myers) since February. The company will incur a one‑time cash severance obligation (~$4.7M) and potential equity settlements tied to the separation agreement. Investors should note the related corporate governance change and that the CFO, Atanas Atanasov, remains on leave (since February 24, 2026) and no separation agreement has yet been reached, which may be relevant to near‑term management stability.
