Antero Midstream (AM) SVP Sheri Pearce Sells 14,000 Shares, Receives RSUs

What Happened

Sheri Pearce, Senior Vice President — Accounting and Chief Accounting Officer of Antero Midstream (AM), was granted 32,651 restricted stock units (RSUs) on March 7, 2026. The RSUs vest one-third on each of the first three anniversaries of March 7, 2026. To cover tax withholding on the RSU settlement, 25,240 shares were withheld at a price of $22.97 (value ≈ $579,763). Separately, Pearce sold 14,000 shares in an open-market transaction on March 10, 2026, for a weighted-average price of $22.76 (total ≈ $318,640; sale prices ranged $22.66–$22.87).

Key Details

  • Grant: 32,651 RSUs awarded on 2026-03-07; vest 1/3 each year over three years (per Plan).
  • Tax withholding (cashless settlement): 25,240 shares withheld on 2026-03-07 at $22.97 (value ≈ $579,763). Withholding amount was determined using the March 6, 2026 closing price.
  • Open-market sale: 14,000 shares sold on 2026-03-10 at a weighted average of $22.76 (≈ $318,640); reported sale price range $22.66–$22.87.
  • Combined shares disposed/withheld: 39,240 shares (25,240 withheld + 14,000 sold); combined value of withheld shares and sale ≈ $898,403.
  • Filing: Form 4 filed March 10, 2026 for transactions on March 7 and March 10 — appears timely.
  • Other RSUs noted: filing references additional previously granted RSUs that remain subject to vesting (139,140 and 81,755 shares, per footnotes).

Context

  • The 25,240-share disposition was a tax-withholding (cashless settlement) related to the RSU grant, not an independent sell decision for cash.
  • The separate 14,000-share sale was an open-market transaction; sales by executives can be routine (taxes, diversification, exercise costs) and do not necessarily signal a view on company prospects.
  • RSU grants vest over time, so the economic interest is spread across future dates rather than an immediate purchase.
