Rhea-AI Filing Summary

Diamondback Energy, Inc. executive vice president and chief engineer Albert Barkmann reported equity compensation and related tax withholding transactions in common stock. He received two awards on March 1, 2026: 3,500 restricted stock units that vest in three equal installments beginning on March 1, 2027, and 6,430 performance-based restricted stock units that had vested as of December 31, 2025 after the compensation committee certified the applicable performance conditions and will settle on March 1, 2026.

To cover tax obligations tied to these vesting and settlement events, the issuer withheld a total of 3,521 shares of common stock at a price of $174.08 per share, reflected through four code "F" transactions. These withholdings relate to performance-based units granted on March 1, 2023 and time-based restricted stock units granted on March 1, 2023, March 1, 2024, and March 1, 2025. Following these grants and withholdings, Barkmann directly held 31,571 shares of Diamondback Energy common stock, and a footnote notes that prior Forms 4 had overstated his ownership by a de minimis amount, which has now been corrected.
