Agreement and Plan of Merger regulatory
"The shares were disposed of pursuant to the Agreement and Plan of Merger, dated March 4, 2025"
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.

"converted into the right to receive 0.043279843 shares of common stock of Parent and cash payable in lieu"
wholly owned subsidiary financial
"with the Issuer surviving the merger as 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.
