BERG MARK STEPHEN 4

What Happened

• Mark Stephen Berg, a director of ProPetro Holding Corp. (PUMP), had 28,181 restricted stock units (RSUs) vest and convert into 28,181 shares on May 18, 2026 (reported on Form 4 filed 2026-05-19).
• The Form 4 records an acquisition (derivative conversion, code M) of 28,181 shares and a simultaneous disposition of 28,181 shares at $0.00. Footnotes state these shares were delivered upon vesting and settlement of previously awarded RSUs.

Key Details

• Transaction date: 2026-05-18; Form 4 filed: 2026-05-19 (timely filing).
• Transaction codes: M (exercise/conversion of derivative). Acquisition: 28,181 shares (price N/A). Disposition: 28,181 shares at $0.00.
• Footnotes: F1–F3 confirm these were RSUs granted May 21, 2025, that vested in full upon the earlier of the day before the 2026 annual meeting and May 21, 2026; each RSU equals one share or cash equivalent.
• Shares owned after the transaction are not specified in the provided excerpt.
• The filing does not indicate a cash sale; the $0.00 disposition is recorded in the derivative line but the Form 4 does not explicitly state the reason for that line (e.g., tax withholding or settlement mechanics).

Context

• This was not an open-market purchase or sale for investment signaling; it reflects RSU vesting and conversion into shares. Such entries often include technical disposition lines related to settlement or tax withholding—check the full filing for detail.
• For retail investors, RSU vesting is routine compensation-related activity by insiders and should be interpreted as part of compensation settlement rather than a directional buy/sell decision.
