"merger of Bravo Merger Sub I, Inc. with and into the Registrant"

Merger Agreement regulatory

"Agreement and Plan of Merger (the “Merger Agreement”)"

A merger agreement is a binding contract that lays out the exact terms for two companies to combine, including the price, what each side will deliver, and the conditions that must be met before the deal is completed. Investors care because it sets the timetable, payouts and risks — like a blueprint or prenup that shows whether the deal is likely to close, how ownership will change, and what could cancel or alter the payout they expect.
