        <footnote id="F1">Grant of time vested restricted stock units (&quot;RSUs&quot;) made pursuant to the Carnival Corporation 2020 Stock Plan. Each RSU represents a hypothetical interest in one share of Carnival Corporation common stock. The RSUs will vest on a 3-year pro-rata basis in February 2024, 2025 and 2026. The RSUs will accumulate dividend equivalents and may only be settled in shares.</footnote>
        <footnote id="F2">The grant was approved by the Compensation Committees as a total value to be received in the form of RSUs.  The Compensation Committees also approved that the number of RSUs were determined by dividing the grant value by the closing price of a share of Carnival Corporation common stock on date of grant.</footnote>
