Agreement and Plan of Merger regulatory

"Pursuant to the Agreement and Plan of Merger, dated as of 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.

Merger financial

"on April 1, 2026, Merger Sub merged with and into the Issuer, with the Issuer continuing as the surviving company"

A merger is when two companies combine into a single business, with ownership and control reorganized so they operate as one entity. For investors it matters because mergers can change the value and risk of holdings—shares may be exchanged, diluted, or rise if the combined company saves costs or gains market power, and the deal often depends on regulatory approval and successful integration like two households joining resources and routines.

beneficial owners financial

"The Reporting Persons ceased to be the beneficial owners of more than five percent of the common stock on April 1, 2026."

Beneficial owners are the people or entities that actually enjoy the economic benefits and control of shares or other assets, even when legal title is held by someone else such as a broker, custodian or trustee. Investors pay attention because beneficial owners hold the real voting power, receive dividends and can influence strategy and takeover outcomes — like the driver of a car who uses and maintains it while the bank holds the title — so disclosure shows who truly controls and benefits.

restricted stock units financial

"with similar treatment for outstanding restricted stock units, including restricted stock units held by Ms. Paul."

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.

Rules 12g-4(a)(1) and 12h-3(b)(1)(i) of the Exchange Act regulatory

"became eligible for delisting from the New York Stock Exchange and termination of registration pursuant to Rules 12g-4(a)(1) and 12h-3(b)(1)(i) of the Exchange Act."
