        <footnote id="F1">Represents restricted stock units granted by AleAnna, Inc. (the &quot;Issuer&quot;) to the reporting person pursuant to the AleAnna, Inc. 2025 Long-Term Incentive Plan (&quot;2025 Plan&quot;) and represents a contingent right to receive one share of common stock of the Issuer or its cash equivalent, as determined at the time of settlement by the Compensation Committee of the Company's Board of Directors (the &quot;Committee&quot;). The restricted stock units will vest in three equal installments, with one-third of the restricted stock units vesting on October 29, 2026, 2027 and 2028, respectively, provided that the reporting is employed by or providing services to the Issuer or subsidiary through each such date.</footnote>
