Agreement and Plan of Merger regulatory
"Pursuant to the Agreement and Plan of Merger, dated February 22, 2026, by and among Arcellx, Inc."
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.
Closing Amount financial
"which had a per share exercise price less than $115 per share (the "Closing Amount"), was canceled"
contingent value right financial
"and (ii) one contractual contingent value right for each share subject to such Company Option"
A contingent value right is a special security that gives its holder the right to receive one or more future payments only if specified events happen, such as a product reaching a sales target or getting regulatory approval. It matters to investors because it offers potential extra payout tied to uncertain outcomes—like a bet that a project will succeed—so it can add upside to a deal while also carrying extra risk and valuation uncertainty.
