BEST ANTHONY JAMES 4

What Happened

• Anthony J. Best, a director of ProPetro Holding Corp. (PUMP), had 28,181 restricted stock units (RSUs) converted into 28,181 shares on May 18, 2026. The Form 4 shows an acquisition via derivative conversion (code M) for 28,181 shares (price N/A) and a corresponding disposition of 28,181 shares at $0.00 (derivative). Footnotes state these shares were delivered upon vesting/settlement of previously awarded RSUs granted May 21, 2025.

• Transaction codes: M (exercise/conversion of derivative); disposition line shows $0.00 — indicates settlement/conversion, not an open-market sale.
• Shares involved: 28,181 RSUs converted to 28,181 shares.
• Price/Value: Acquisition listed as N/A; disposition listed at $0.00 per share (no cash proceeds reported).
• Shares owned after transaction: not specified in the filing.
• Footnotes: F1–F3 explain settlement on vesting, RSUs convertible to stock or cash, and original grant date May 21, 2025 with vesting tied to the 2026 annual meeting/May 21, 2026.

Context

• RSU conversions like this are routine compensation events: RSUs vest and convert into shares (or cash) per grant terms. The $0.00/disposition and derivative-code lines reflect internal settlement mechanics rather than a market sale — this does not signal a buy or sell decision in the open market. Retail investors should view this as executive compensation/settlement activity, not necessarily an indicator of the director’s market view.
