Filing Type: Form 10-Q (Quarterly Report)
Period Ended: March 31, 2026
Business Overview: NB Bancorp is a bank holding company operating primarily through its subsidiary, Needham Bank, in eastern Massachusetts and southern New Hampshire.

Key Financial Metrics

Material Changes vs. Prior Period

• Revenue Growth: Net interest income surged 49.0% year-over-year, driven by a 39.5% increase in average loan balances following the Provident acquisition. The yield on interest-earning assets expanded 3 basis points to 6.41%.
• Expense Increases: Noninterest expense rose 48.9% to $42.7 million. This was primarily due to increased salaries and benefits ($6.3 million increase) from higher headcount, data processing costs ($1.7 million increase), and merger-related expenses ($534,000).
• Provision for Credit Losses: The provision increased significantly to $6.33 million from $1.16 million. This was driven by portfolio growth, peer credit loss trends, and elevated qualitative risk factors in the commercial and industrial portfolio. Gross charge-offs were $13.8 million, largely attributed to two large Purchased Credit-Deteriorated (PCD) loans totaling $12.4 million which were previously reserved for.
• Balance Sheet Expansion: Total assets grew to $7.23 billion. Net loans increased by $231 million, with significant growth in commercial and industrial loans (+13.4%) and construction/development loans (+7.1%).
• Shareholder Returns: The company repurchased 1,288,509 shares for $27.8 million and paid $3.2 million in dividends, contributing to the decrease in shareholders' equity.

Guidance, Outlook, and Risks

• Outlook: Management continues to focus on prudently growing the balance sheet by diversifying into higher-yielding commercial loans to improve net margins. The company maintains a strategy of managing interest rate risk through asset/liability management and the use of derivatives.
• Interest Rate Risk: As of March 31, 2026, the company is asset-sensitive. A 200 basis point increase in rates is projected to increase Net Interest Income by 4.0%, while a 200 basis point decrease would reduce it by 2.6%.
• Liquidity: The company maintains strong liquidity with $375 million in cash equivalents, $892.7 million in unused FHLB borrowing capacity, and $1.01 billion available via the Federal Reserve's Borrower in Custody program.
• Key Risks:
  • Cannabis Industry Exposure: The company holds $466.8 million in loans and $455.6 million in deposits related to the cannabis industry. Regulatory changes affecting this sector pose a material risk.
  • Credit Quality: Elevated charge-offs in the commercial and industrial sector and potential volatility in commercial real estate values.
  • Interest Rate Volatility: Changes in the yield curve could impact net interest income and the fair value of the securities portfolio.

Investor Verification Checklist

• PCD Loan Charge-offs: Verify the impact of the $12.4 million charge-off on PCD loans from the Provident acquisition and confirm that these were fully reserved at acquisition, resulting in no additional economic loss.
• Cannabis Exposure: Review the concentration of loans ($466.8M) and deposits ($455.6M) in the cannabis industry and assess the collateral quality (primarily real estate) against potential regulatory shifts.
• Non-GAAP Adjustments: Reconcile GAAP Net Income ($14.98M) to Operating Net Income ($15.79M) by reviewing the add-backs for merger costs ($534k) and non-recurring fees ($500k).
• Share Repurchase Program: Confirm the remaining capacity under the stock repurchase program (1,000,000 shares remaining as of March 31, 2026) and the average cost per share ($21.55).
• Deposit Composition: Analyze the mix of brokered deposits ($570.1M) versus core deposits to assess funding stability and cost sensitivity.
