Agreement and Plan of Merger regulatory

"Pursuant to the Agreement and Plan of Merger (the "Merger Agreement"), dated January 6, 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.

restricted stock units financial

"Represents an equal number of restricted stock units ("RSUs")."

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.

outside director compensation policy financial

"Pursuant to Issuer's outside director compensation policy, immediately before the effective time..."

Per Share Price financial

"equal to the product of (a) $24.00 (the "Per Share Price") multiplied by (b) the total number of shares..."

Effective Time regulatory

"immediately before the effective time of the Mergers (the "Effective Time"), each RSU award..."

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.
