What Happened
Jeffrey Slocum, Halliburton's Executive Vice President and Chief Operating Officer, transferred 3,404 shares of Halliburton common stock back to the company on March 5, 2026 to satisfy federal tax withholding obligations. The shares were valued at $36.00 each (closing price on Feb 27, 2026), for a total of about $122,544. This was a tax-withholding disposition (code F), not an open-market sale.

Key Details

  • Price per share reported: $36.00; total value ≈ $122,544

  • Shares issued: Performance Unit shares were issued Feb 27, 2026; withholding occurred March 5, 2026 (per filing footnotes)
  • Shares owned after transaction: Not disclosed in this Form 4
  • Filing timeliness: Report appears timely (transaction period 2026-03-05; filing 2026-03-06)

Context
These shares were withheld by the company to cover tax on restricted/performance shares that vested (a common “cashless” withholding method). Such withholding-to-issuer transactions are routine and do not necessarily indicate the insider is reducing their overall exposure via an open-market sale.
