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.
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.
exercise price per share financial
"with an exercise price per share equal to the exercise price applicable"

"multiplied by 1.425, rounded down to the nearest whole share"
