Rhea-AI Filing Summary

Gulfport Energy Corp’s president and CEO, who is also a director, reported the vesting of performance-based restricted stock units. On January 2, 2026, 54,558 shares of common stock were acquired at $0 when performance-based RSUs granted on January 24, 2023 for the period from January 1, 2023 to December 31, 2025 fully vested after the compensation committee certified the performance results.
