Diamondback Energy amends stockholder pact; two directors resign in board stepdown

Neutral Impact 3 of 5 leadership Written later

Diamondback Energy amended its Stockholders Agreement with SGF FANG Holdings, LP, tying the Stephens group's board designation rights to its ownership level. Directors Darin Holderness and Lance Robertson resigned from the board in connection with a Board Stepdown under that agreement, not because of any disagreement with the company.

Key points

  • Amendment dated September 29, 2026 lets the Stephens Majority designate two directors if Stephens Stockholders own at least 10% but less than 25% of outstanding shares.
  • The Stephens Stockholders would have no designated directors if they own less than 10% of outstanding shares.
  • Darin Holderness resigned from the board on September 29, 2026; Lance Robertson resigned on September 30, 2026.
  • Resignations were stated to be unrelated to any disagreement with the company on operations, policies or practices.
