Vion Michele 4

What Happened
Vion Michele, a director of ProPetro Holding Corp. (PUMP), had 28,181 restricted stock units (RSUs) vest and be settled into common shares on May 18, 2026. The Form 4 shows 28,181 shares were acquired upon conversion/settlement of the derivative (code M) and an equal 28,181 shares were recorded as disposed at $0.00 (derivative). No cash proceeds are reported in the filing. This was a compensation-related vesting/settlement event rather than an open-market purchase or voluntary sale.

Context
This was a routine RSU vesting/settlement (compensation) event, not an open-market buy or sell that would signal the insider’s market view. The identical acquired and disposed share counts with $0 proceeds are consistent with a net-share settlement or withholding arrangement to satisfy obligations (e.g., taxes or exercise requirements), though the filing does not state the exact mechanism.
