ProPetro (PUMP) CAO Celina Davila Receives RSU Shares, Withholds 485

What Happened

• Celina Davila, Chief Accounting Officer of ProPetro Holding Corp. (PUMP), had 1,990 restricted stock units (RSUs) vest on September 4, 2026. Those RSUs converted into 1,990 shares of common stock. To cover tax withholding, 485 of those shares were surrendered (withheld) at an implied price of $11.10 per share, equal to $5,384, leaving a net 1,505 shares delivered to her.

• Tax withholding (code F): 485 shares withheld to satisfy taxes at $11.10/share, totaling $5,384.
• Net shares received: 1,505 (1,990 vested minus 485 withheld).
• Footnotes: RSUs were from a 9/4/2023 grant of 5,970 RSUs vesting in three substantially equal annual installments (i.e., 1,990 shares per installment). RSUs represent the right to receive one share (or cash equal to FMV).
• Shares owned after transaction: not disclosed in the provided filing.
• Timeliness: Filing appears timely. The vesting date was 9/4/2026 and the Form 4 was filed 9/8/2026; the filing deadline was extended by the Labor Day holiday.

Context

• This was a standard RSU vesting and tax-withholding event (not an open-market buy or a sale). Withholding shares to cover taxes is common and does not necessarily signal the insider's view of the stock. The filing shows conversion of RSUs (a derivative award) into shares and a cashless-type withholding to satisfy tax obligations.
