Agreement and Plan of Merger regulatory
"Pursuant to the terms of the Agreement and Plan of Merger, dated as of April 22, 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.
Parent RSU Award financial
"each award of restricted stock units (a "Parent RSU Award") owned by the reporting person"
forfeiture restrictions financial
"Forfeiture restrictions lapsed with respect to one-third of the 2024 Parent RSU Award"
Effective Time regulatory
"owned by the reporting person as of the Effective Time was canceled in exchange for cash"
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.
Parent Common Stock financial
"multiplied by the closing price of a share of Parent Common Stock on the NYSE"
