Rosenthal Gary L 4

What Happened

• Gary L. Rosenthal, a director of Cactus, Inc. (WHD), received a new award of 2,559 restricted stock units (RSUs) on March 10, 2026 that vest on the first anniversary of the grant. On the same date, 2,524 previously granted RSUs (from March 10, 2025) vested, converted into 2,524 shares, and those converted shares were recorded as disposed at $0 on the Form 4 (common when shares are withheld to satisfy tax withholding obligations).

Key Details

• Transaction dates: March 10, 2026 (grant and RSU conversion/related disposition); Form 4 filed March 12, 2026 (timely filing).
• Grants/Conversions: +2,559 RSUs granted @ $0.00 (award); 2,524 RSUs from 3/10/2025 vested and converted to 2,524 shares, then disposed at $0.00 on the report.
• Shares owned after transaction: not specified in the provided filing data.
• Footnotes: F1 explains RSUs convert 1-for-1 to Class A common stock upon vesting. F2 confirms the 2/559 RSU grant vests March 10, 2027. F3 confirms the 2,524 RSUs were a March 10, 2025 grant that vested March 10, 2026.
• Filing timeliness: Filed two days after the transaction date — appears timely (not late).

Context

• These transactions are routine compensation events: the new 2,559 RSUs are an award that will convert to shares upon future vesting; the 2,524-unit event was a scheduled vesting/conversion. The reported $0 disposal typically reflects shares withheld or surrendered to cover taxes rather than an open-market sale. Such awards/withholdings are standard director compensation and do not directly indicate a buy/sell signal by the insider.
