Agreement and Plan of Merger regulatory
"entered into an Agreement and Plan of Merger, dated 4/13/26 (the Merger Agreement)"
An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.
Assumed PSU Awards financial
"performance vesting conditions were deemed achieved at 200% of target (Assumed PSU Awards)"
Somnigroup RSU financial
"converted into the right to receive 0.1455 restricted stock units with respect to shares of Somnigroup common stock (each, a Somnigroup RSU)"

"The total in columns 5 and 7 represents the portion of the Assumed PSU Awards...converted into a Somnigroup RSU that represents a conditional right to receive a cash payment"

"shares beneficially owned by the reporting person held in trust in the Leggett retirement plan"
exercise price financial
"except the exercise price will equal the quotient obtained by dividing (i) the exercise price of the Leggett option, by (ii) 0.1455"
The exercise price is the fixed amount at which you can buy or sell an asset, like a stock, when using an options contract. It matters because it helps determine whether exercising the option will be profitable or not, depending on the current market price. Think of it as the set price you agree on today to buy or sell later.
