At the effective time of the Merger (the Effective Time), each outstanding Leggett performance stock unit for which the performance period had not yet ended was assumed by Somnigroup and converted into the right to receive 0.1455 restricted stock units with respect to shares of Somnigroup common stock (each, a Somnigroup RSU) on the same terms, except the performance vesting conditions were deemed achieved at 200% of target (Assumed PSU Awards). The total represents a deemed acquisition by the reporting person of Leggett shares underlying the portion of the Assumed PSU Awards that, by their original terms, were to be settled in shares of Leggett common stock.

Such Somnigroup RSUs will vest on the same schedule as the Assumed PSU Awards, on December 31, 2026, December 31, 2027 and December 31, 2028, respectively, and cash payments therefor will be delivered to the reporting person no later than March 15 following the respective vesting date.
