Northfield Bancorp, Inc. (NASDAQ:NFBK) disclosed that director Paul Stahlin bought 10,000 shares of the company's common stock on March 17, 2026, according to a Form 4 filing with the Securities and Exchange Commission.

The filing indicates that, after the transaction, Stahlin directly owns 54,354 shares of Northfield Bancorp common stock.

In addition to the outright shares, Stahlin is listed as the holder of 4,383 restricted stock units. Each unit represents a contingent right to receive cash equal to the value of one share of Northfield Bancorp common stock on the applicable vesting date, and the award is scheduled to vest one year from its grant date.

The purchase comes as Northfield Bancorp shares have risen by more than 15 percent year-to-date and trade near the company's 52-week high of $14.05.
