Agreement and Plan of Merger regulatory
"Pursuant to the Agreement and Plan of Merger dated as of January 31, 2026, by and among"
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.
effective time of the merger regulatory
"at the effective time of the merger between Northfield Bancorp, Inc, and Newco, each"
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.
restricted stock unit financial
"Pursuant to the Merger Agreement, each restricted stock unit was converted into the right"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
SEP financial
""Common Stock" transaction with indirect ownership nature described as "By SEP""
IRA financial
""Common Stock" transaction with indirect ownership nature described as "By IRA""
An individual retirement account (IRA) is a savings account designed to help people put aside money for their retirement, often with tax advantages that encourage long-term savings. It matters to investors because it can grow over time, providing financial security later in life, and offers benefits that can reduce current taxes or allow investments to compound more effectively.
