Davila Celina A 4

What Happened
Celina A. Davila, Chief Accounting Officer of ProPetro Holding Corp. (PUMP), had 3,344 restricted stock units (RSUs) vest and convert into 3,344 shares on February 1, 2026. Of those shares, 992 were withheld to satisfy tax withholding at $11.49 per share, generating $11,398 in tax payment. The RSU conversion is recorded as a derivative exercise/settlement (Form 4 transaction code M) and the withholding is recorded as a disposition for tax purposes (code F).

• Tax withholding: 992 shares withheld/disposed at $11.49 each, total $11,398.
• Net shares retained from this vesting: 3,344 − 992 = 2,352 shares.
• Footnotes: RSUs represent contingent rights to receive common stock or cash; shares were delivered upon vesting and some withheld to cover taxes. The RSUs were originally granted Feb 1, 2023 and vest in three substantially equal annual installments.

Context
This was an RSU vesting and tax-withholding event, not an open-market buy or voluntary sale. The withholding is a routine cashless method to cover tax obligations and does not by itself indicate a buy/sell signal. Transaction codes: M = conversion/exercise of derivative (RSU settlement); F = shares withheld to pay taxes.
