        <footnote id="F1">The shares were acquired upon the certification by the Leadership Development, Inclusion and Compensation Committee of the Board of Directors for the satisfaction of performance criteria underlying an award of performance stock units (PSUs) granted to the Reporting Person on May 3, 2023 under the terms of Alphabet's Amended and Restated 2021 Stock Plan and applicable PSU award agreement. The award provided that if Alphabet's total shareholder return (TSR) performance relative to S&amp;P 100 companies is between the 25th percentile (for 50% target payout) and 75th percentile (for 200% target payout) for the three-year performance period ending December 31, 2025, the PSU payout will be determined by linear interpolation. Alphabet's TSR for the three-year performance period was 203.65%, which ranked Alphabet's TSR at the 92.86th percentile relative to S&amp;P 100 companies, resulting in a payout of 200% of target or 227,313 shares, including share-settled dividends.</footnote>
        <footnote id="F2">Shares withheld to satisfy tax obligations arising out of vesting of the Reporting Person's PSUs.</footnote>

    <remarks>This amendment is being filed to correct the number of shares acquired, which was inadvertently reported as 113,568 on the Form 4 filed on January 15, 2026. The actual number of shares acquired was 227,313.</remarks>
