Agreement and Plan of Merger financial

"Represents shares of Issuer Common Stock received pursuant to the Agreement and Plan of Merger, dated December 29, 2025"

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.

Exchange Ratio financial

"was converted into the right to receive 0.85 shares of Issuer Common Stock (the "Exchange Ratio")"

The exchange ratio is the number used to decide how many shares of one company you get for each share you own in another company during a merger or acquisition. It’s like a recipe that tells you how to swap shares fairly, ensuring both companies’ values are balanced. This ratio matters because it determines how ownership divides between the companies' shareholders.

restricted stock units financial

"Includes 4,080 restricted stock units acquired pursuant to the terms of the Merger Agreement"

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.

cliff vest financial

"Includes 4,080 restricted stock units ... which cliff vest on January 30, 2027"

A cliff vest is a schedule for stock options or restricted shares where no ownership rights are earned until a fixed date, after which a set portion becomes fully owned all at once — like a probation period that suddenly unlocks pay. Investors watch cliff vests because they influence when insiders can sell shares, affect staff retention and dilution timing, and help predict short-term changes in a company’s shareholder makeup.
