NBBK NB Bancorp, Inc. Insider Trading

NBBK President & CEO Campanelli buys 3,000 shares for $57,546.60 via 9 transactions at avg $19.18 amid 30-day -13.5% decline

Joseph P Campanelli, President & CEO of NB Bancorp, executed 9 separate open-market purchases totaling 3,000 shares for $57,546.60 on 2026-05-15, increasing his holdings by 3,000 shares to 377,790 shares post-transaction. The blended average purchase price of $19.18 compares to a current price of $19.47 (at time of filing), occurring against a backdrop of significant recent weakness: the stock is down 13.5% over the past 30 days and 12.6% over 90 days. His prior trades at NBBK have not demonstrated positive timing patterns, with 5 earlier buys from 2026-04-24 all showing negative returns at both the 30-day and 90-day marks, with a 90d win rate of zero. While his cross-ticker track record shows a 45.00% 90d win rate with average 90d returns of +6.2%, that performance has not translated to timing success in this specific stock.

NBBK C-suite insider buys 26,000+ shares at modest discount amid multi-quarter pullback

A senior executive at NB Bancorp made a substantial open-market purchase of over 26,000 shares, demonstrating meaningful conviction in the company's value. The timing is notable: the stock has retreated from its highs over recent months and is currently trading at a discount to where it traded earlier this year, suggesting the insider views the pullback as an opportunity rather than a warning sign. NB Bancorp is a solidly profitable financial institution with reasonable valuation metrics, generating strong quarterly earnings and supported by a modest market capitalization. The insider's willingness to deploy significant capital at current levels—particularly the larger 24,000+ share tranche representing over 6% of their holdings—signals confidence that the market has overreacted to recent headwinds. This behavior is especially credible coming from a C-suite officer who likely has deep visibility into company operations and near-term catalysts.
