Insights

Equity compensation analyst

Routine equity award vesting with tax share withholding, no open-market buying or selling.

Brendan E. Krueger received 99,242 Antero Midstream shares at $0.0000 per share from performance share units that vested based on a multi‑year return on invested capital metric. This reflects long-term incentive compensation rather than a discretionary purchase.

In connection with this vesting, 43,847 shares were withheld at $22.1200 per share to satisfy tax obligations, a standard non-cash disposition method where the issuer retains shares instead of a cash tax payment. Following these changes, Krueger directly holds 633,545 shares, including 247,799 unvested restricted stock units, indicating substantial ongoing equity exposure.
