CAMPANELLI JOSEPH P 4/A

What Happened

• Joseph P. Campanelli — President, CEO, Director and Chairman of NB Bancorp (NBBK) — made two open-market purchases on March 6, 2026, acquiring 2,000 shares at $20.78 ($41,560) and 3,000 shares at $20.77 ($62,310), for a total of 5,000 shares costing $103,870. These were purchases (transaction code P), which are typically viewed as a more directly bullish signal than sales. The Form 4 was submitted as an amended filing on March 20, 2026.

Context

• These were straight open-market purchases (not option exercises or awards) and the shares were acquired outright rather than sold immediately. Purchases by an insider can be interpreted by some investors as a sign of confidence, but they are only one data point. The restricted-stock footnotes describe separate awards with multi-year vesting schedules and are not the same as the open-market buys reported here.
