F1Leggett & Platt, Incorporated ("Leggett"), Somnigroup International Inc. ("Somnigroup"), and Sparrow Unity Corporation, a direct, wholly owned subsidiary of Somnigroup ("Merger Sub") entered into an Agreement and Plan of Merger, dated April 13, 2026 (the "Merger Agreement") pursuant to which Merger Sub merged with and into Leggett (the "Merger"). The total reflects shares of Leggett common stock and outstanding Leggett restricted stock unit awards, each of which, at the effective time of the Merger (the "Effective Time"), was converted into the right to receive 0.1455 shares of Somnigroup common stock or Somnigroup restricted stock units (to be settled in cash), as applicable, pursuant to the terms of the Merger Agreement.
F2At the Effective Time, each outstanding Leggett stock option held by the reporting person was assumed by Somnigroup and converted into the right to receive 0.1455 options to purchase shares of Somnigroup common stock under the same terms, except the exercise price will equal the quotient obtained by dividing (i) the exercise price of the Leggett option, by (ii) 0.1455, rounded up to the nearest whole cent.
