The governance step-down and director resignations formalize a negotiated settlement with the Stephens activist group, reducing board influence as their stake likely falls below 10%. No immediate trading catalyst. Monitor future 13D filings for any further stake changes or renewed activism if the Stephens group rebuilds above 10%.

Executive Summary
Diamondback Energy amended its Stockholders Agreement with the Stephens Majority (SGF FANG Holdings, LP) to permanently reduce board representation rights: two directors if the Stephens group holds 10-25% of outstanding shares, and zero directors if below 10%. In connection with this Board Stepdown, directors Darin Holderness and Lance Robertson resigned effective September 29-30, 2026, with no disagreement with the Company. The amendment follows a recent SC 13D/A filed 13 days prior by the same activist group, suggesting a negotiated governance settlement rather than a hostile campaign escalation.
