Explanation of Responses:

Id Content
F1 Performance-based restricted stock award ("PSA") granted in 2025 subject to performance-based and time-based vesting over two years. Performance-based vesting criteria, which included a combination of profitability of the Issuer's services businesses, growth of the Issuer's leasing portfolio and the viability of the Issuer's Sustainable Aviation Fuel initiative, were certified on March 16, 2026. Each PSA represents a contingent right to receive one share of the Issuer's common stock upon vesting.
F2 Return to Issuer of previously restricted shares to satisfy withholding tax liability.
F3 Reported amount has been adjusted to reflect the actual number of PSAs earned, based on the extent to which the performance-based vesting criteria were achieved. The remaining 2,229 PSAs of the 100% target amount reported in the Form 4 filed by the Reporting Person on January 6, 2025 were forfeited.
