Munoz Adam 4

What Happened

• Adam Munoz, President and COO of ProPetro Holding Corp. (PUMP), had previously awarded performance stock units (PSUs) vest and settle on 2026-01-19. He was issued 113,332 shares of common stock (reported as an acquisition at $0.00).
• To cover tax withholding on the PSU settlement, 30,834 of those shares were withheld/disposed at a price of $10.29 per share for a withholding value of $317,282. Net new shares received by Munoz = 82,498 (113,332 issued − 30,834 withheld).
• This is a compensation-related award/settlement rather than an open-market buy or a voluntary sale.
