CEO‑linked entity reports open‑market net sales of 136,037 Cactus shares.

Two open‑market sales of Cactus, Inc. Class A Common Stock were reported for an entity associated with Chairman and CEO Scott Bender. The transactions on March 6, 2026 and March 10, 2026 totaled 136,037 shares at per‑share prices near $50.

The filing states that Bender Investment Company executed these sales, and Scott Bender disclaims beneficial ownership beyond his pecuniary interest. After the latest transaction, 106,801 shares are reported as owned, indicating a remaining equity position alongside the disclosed disposals.

Because the filing shows only sales and no new grants or option exercises, the net effect is a reduction in the reported stake rather than portfolio rebalancing from derivative exercises. The broader significance depends on Bender’s total holdings across all accounts, which are not fully detailed here.
