Agreement and Plan of Merger regulatory
"Pursuant to the Agreement and Plan of Merger dated as of July 15, 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.
contingent value right financial
"one contingent value right per share (each, a "CVR" and collectively, the "CVRs")"
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.
Effective Time regulatory
"At the effective time of the Merger (the "Effective Time"), each outstanding stock option"
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.
Merger Sub regulatory
"Albali Acquisition Corporation, a Delaware corporation and indirect wholly owned subsidiary of Parent ("Merger Sub")"
A merger sub is a temporary, wholly owned subsidiary that an acquiring company creates to carry out a merger with another firm. Think of it as a wrapper used to combine two businesses—this can simplify legal and tax steps, isolate liabilities, and help preserve the target’s contracts or stock structure, so investors watch it because the chosen approach affects deal mechanics, shareholder votes, potential dilution, and legal or tax risk.
wholly owned subsidiary financial
"with the Company surviving 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.
