Agreement and Plan of Merger regulatory
"Pursuant to the Agreement and Plan of Merger dated as of January 31, 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 unit financial
"Pursuant to the Merger Agreement, each restricted stock unit was converted"
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.
effective time of the merger regulatory
"at the effective time of the merger between Northfield Bancorp, Inc. and Newco"
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.
401(k) financial
"Common Stock transaction with nature_of_ownership noted as By 401(k)"
A 401(k) is a type of retirement savings plan offered by employers that allows workers to set aside a portion of their paycheck before taxes are taken out. The money saved in a 401(k) can grow over time through investments, helping individuals build funds for their future retirement. It matters to investors because it provides a tax-advantaged way to save and invest for long-term financial security.
Merger Agreement regulatory
"Pursuant to the Merger Agreement, each restricted stock unit was converted"
A merger agreement is a binding contract that lays out the exact terms for two companies to combine, including the price, what each side will deliver, and the conditions that must be met before the deal is completed. Investors care because it sets the timetable, payouts and risks — like a blueprint or prenup that shows whether the deal is likely to close, how ownership will change, and what could cancel or alter the payout they expect.
