Reported

The EAIP also includes a maximum award opportunity of 125% of target and contains customary provisions regarding termination of employment, clawback and compliance with Section 409A of the Internal Revenue Code of 1986, as amended.

Also stated in this filing

  • On April 22, 2026, the Company's Board of Directors (the "Board") approved and adopted the NB Bancorp, Inc. and Needham Bank Executive Annual Incentive Plan (the "EAIP"), effective as of January 1, 2026.
  • The EAIP provides senior management executives of the Company and its affiliates with the opportunity to earn annual cash incentive awards, as determined by the Compensation Committee of the Board (the "Committee").
  • Under the EAIP, the Committee will establish target award opportunities (expressed as a percentage of base salary), performance goals, and a performance formula for each performance period (generally, the Company's fiscal year).
  • Awards are contingent upon the achievement of performance goals established by the Committee and may be adjusted, reduced or increased in the Committee's discretion, subject to the terms of the EAIP.

Where this comes from

A public company must file a current report on Form 8-K with the SEC within four business days when a director leaves or is elected, or when its chief executive, chief financial, chief accounting or chief operating officer, or another named executive, departs or is appointed. That disclosure goes under Item 5.02 of the report.

Every change on this page is taken from one of those filings and quoted in the company's own words, with a link to the filing, so it can be checked at the source. Where a filing names the person, the role and the date a change takes effect, they are shown beside the quote. Where it does not, the quote stands on its own. A filing states what changed; it rarely states why, and neither does this page.
