About NB Bancorp, Inc.
About NB Bancorp, Inc.
NB Bancorp's Needham Bank subsidiary held a total loan portfolio in which commercial real estate and multifamily loans made up $2.44 billion, or 40.7%, as of December 31, 2025, following the November 15, 2025 acquisition of Provident Bancorp and its BankProv subsidiary for $111.8 million in cash plus 5.9 million shares of common stock. The acquisition added roughly $1.40 billion in assets, extending Needham Bank's footprint from its core Greater Boston market into southern New Hampshire and adding a national mortgage warehouse lending platform. Needham Bank is regulated by the Massachusetts Commissioner of Banks and the Federal Reserve Board as its primary federal regulator, with FDIC deposit insurance.
Needham Bank earns net interest income by taking deposits and funding commercial real estate and multifamily loans (40.7% of the portfolio), one-to-four-family residential and home-equity loans (19.6%), commercial and industrial loans split across Small Business, Middle Market and Structured Finance divisions (16.8%), construction and land development loans (12.2%), mortgage warehouse loans acquired through Provident (4.7%), and consumer loans (3.4%). The bank's Structured Finance division serves larger commercial customers with more than $50 million in annual revenue across industries including cannabis-related entities and renewable energy, an area management describes as a competitive advantage due to specialized underwriting knowledge. Funding comes from core deposits supplemented by $196.2 million of FHLB advances and $535.7 million of brokered deposits at year-end 2025, and the bank has invested heavily in cash-management products to capture full commercial banking relationships from its Structured Finance and cannabis-related customer base.
Show full overview
Needham Bank's commercial real estate and multifamily concentration of 40.7% of total loans, up from 39.1% a year earlier, sits well above the 30% threshold regulators typically flag as material CRE concentration risk, and the bank's own 10-K acknowledges the risk of geographic concentrations in its loan portfolios as a factor its lending diversification strategy is designed to address. With $535.7 million in brokered deposits and $196.2 million in FHLB advances supplementing core deposits as of December 31, 2025, Needham Bank's funding mix carries wholesale-reliance risk that could tighten alongside any CRE credit-quality deterioration in its concentrated Greater Boston and expanding New England markets.
