        <footnote id="F1">These shares were acquired pursuant to the vesting of performance share units (PSUs). The number of PSUs that vested was determined based on Logitech's weighted average revenue growth, total shareholder return (TSR) relative to the other companies in the Russell 3000 index and non-GAAP operating income, each over a three-year period from April 1, 2020 through March 31, 2023.</footnote>
