Agreement and Plan of Merger regulatory
"transactions contemplated by the Agreement and Plan of Merger (the "Merger Agreement")"
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 restricted stock units relating to shares of SkyWater common stock."
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.
Effective Time regulatory
"At the effective time of the First Merger (the "Effective Time"), each share of SkyWater"
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.
cash in lieu of any fractional shares financial
"0.4883 shares of common stock of IonQ plus cash in lieu of any fractional shares."
