Key Details

• Transaction date: 2026-02-27; Filing date: 2026-03-02 (filed within required reporting window).
• Withheld/disposed shares: 172,294 shares at $233.89 = $40,297,844 (reported as multiple F-code tax-withholding dispositions).
• Awards received: 51,053 RSUs (time-based) and 76,580 RSUs (derivative, market-based performance award).
• Vesting notes:
  • Time-based RSUs vest in three equal installments on 02/27/2027, 02/27/2028 and 02/27/2029. (F1)
  • Performance-based RSUs vest 0%–150% on 02/27/2029 based on Lam’s TSR vs. the PHLX Semiconductor TR Index for 02/02/2026–02/01/2029. (F4)
• The disposals coded “F” represent shares automatically withheld to satisfy tax withholding upon vesting (cashless withholding), not open-market sales. (F3)
• The filing notes amounts include shares subject to unvested RSUs; the filing excerpt did not list a post-transaction total beneficial ownership figure. (F2)

Context

• This was primarily an awards vesting event with automatic tax withholding (routine corporate compensation mechanics), not an active open-market sale. Performance RSUs are contingent on future relative TSR performance and may pay out between 0%–150% at the 2029 measurement date. Such withholding transactions are common and do not necessarily signal the insider’s view on the stock.
