Key Terms

4 terms

Agreement and Plan of Merger regulatory

"entered into an Agreement and Plan of Merger, dated April 13, 2026"

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.

restricted stock unit awards financial

"shares of Leggett common stock and outstanding Leggett restricted stock unit awards"

Restricted stock unit awards are company promises to deliver a specific number of shares to employees or service providers in the future once conditions—such as staying with the company for a set time or meeting performance targets—are met. They matter to investors because when the promises convert into actual shares they increase the total share count and can reduce earnings per share, while also aligning recipients’ interests with stock performance much like deferred pay that turns into ownership if goals are met.

Merger Sub regulatory

"Sparrow Unity Corporation, a direct, wholly owned subsidiary of Somnigroup ("Merger Sub")"

A merger sub is a temporary, wholly owned subsidiary that an acquiring company creates to carry out a merger with another firm. Think of it as a wrapper used to combine two businesses—this can simplify legal and tax steps, isolate liabilities, and help preserve the target’s contracts or stock structure, so investors watch it because the chosen approach affects deal mechanics, shareholder votes, potential dilution, and legal or tax risk.

Effective Time regulatory

"each of which, at the effective time of the Merger (the "Effective Time"), was converted"

The exact clock time when a regulatory filing, approval, or corporate action formally becomes legally active; from that moment the change is binding and can be acted on. Investors care because the effective time marks when ownership, rights, trading rules, or new securities take effect — like a light switch turning on a contract or transaction — which determines when risks, benefits and market reactions begin.
