Agreement and Plan of Merger regulatory
"pursuant to the Agreement and Plan of Merger, dated February 16, 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.
Per Share Merger Consideration financial
"converted into the right to receive an amount in cash equal to $180.00 per share, without interest (the "Per Share Merger Consideration")"
restricted stock units financial
"each of the Issuer's restricted stock units ("RSUs") held by the Issuer's non-employee directors was canceled"
Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.
wholly owned subsidiary financial
"the Issuer continuing as the surviving corporation and a wholly owned subsidiary of Parent"
A wholly owned subsidiary is a company whose entire ownership is held by another company (the parent), so the parent controls decisions, operations, and finances. Think of it as a fully controlled branch that runs as its own legal entity but whose results flow straight into the parent’s financial statements; investors watch these structures because they affect consolidated revenue, risk exposure, and how profits, liabilities, and cash flow are allocated across the corporate group.
