Footnotes from the filing
On 03/01/2023, the Reporting Person received a grant of 35,950 Market-based Performance Restricted Stock Units vesting between 0% and 150% on 03/01/2026. The vesting of this award is based on the total return stock price performance of Lam Research shares (assuming reinvestment of dividends) relative to the market price performance of the PHLX Semiconductor Sector Total Return Index, comparing the 50-trading day trailing average closing price over the performance period from 02/01/2023 through 01/31/2026.
The amount reported includes shares subject to unvested restricted stock units.
