- The market‑based performance RSUs will vest between 0% and 150% on 02/27/2029 based on Lam’s total shareholder return relative to the PHLX Semiconductor Total Return Index over 02/02/2026–02/01/2029 (F4).

Context

This was not an open‑market sale but routine tax‑withholding upon RSU vesting (common for executive vesting events). The awards are compensation (acquisitions at $0.00); the withheld shares are used to satisfy tax obligations rather than signaling a discretionary sale. The market‑based RSUs carry performance risk and may pay out between 0–150% at final vesting in 2029.
