(3) On February 27, 2026, the reporting person was granted 22,859 RSUs under the Company's 2023 Omnibus Incentive Plan, as may be amended from time to time (the "Plan"), pursuant to the 2026 long-term incentive program approved by the Board of Directors (the "2026 LTIP"). The RSUs vest in substantially equal installments on each of the first three (3) anniversaries of the grant date, subject to continued service.

Achievement at threshold results in a 50% payout opportunity, while achievement at maximum results in a 200% payout opportunity.
