Agreement and Plan of Merger regulatory

"Pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), entered into on March 2, 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.

Merger Consideration financial

"was converted into the right to receive $16.50 per share in cash without interest ("Merger Consideration")."

Merger consideration is the total payment a company or buyer offers to shareholders of a target company in exchange for combining the two businesses, and can include cash, shares in the surviving company, debt assumption, or a mix of these. Investors care because the form and amount affect the deal’s value, tax consequences, immediate cash received versus future ownership, and the risk and upside of holding new shares — similar to choosing between cash now or stock that could grow later.

Company Restricted Shares financial

"Includes unvested shares of Company common stock subject to forfeiture conditions (the "Company Restricted Shares")."

effective time of the merger regulatory

"immediately prior to the effective time of the merger and was automatically converted..."

The effective time of the merger is the exact moment when a planned combination of two companies legally takes effect, usually specified in the merger agreement and reflected by the formal filing or timestamp. For investors, it is the point when ownership, voting rights, financial reporting and control shift—like a light switch flipping that joins two rooms into one—so it determines when shares convert, who controls corporate decisions and which results appear in financial statements.
