Net interest margin edges up to 2.76%

• Northfield Bancorp reported a Q1 2026 net interest margin of 2.76%, compared with 2.54% in Q3 2025 and 2.57% in Q2 2025, while trailing 12 month net interest margin at Q4 2025 was 2.55%.
• For a bullish view, what stands out is that this higher margin in Q1 2026 sits alongside quarterly net income of US$11.8 million, after trailing 12 month net income had been only US$4.8 million. This raises questions for bulls about how much of the recent improvement is driven by underlying spread versus the rebound from last year’s one off loss.
  • Supporters of a stronger future earnings path can point to the move from a 2.1% net interest margin in Q4 2024 on a trailing basis to 2.55% by Q4 2025, together with revenue over the trailing 12 months rising from US$127.0 million at Q4 2024 to US$154.8 million at Q1 2026.
  • At the same time, the very large one off loss of US$42.7 million that pulled trailing net margin down to 3.1% from 24.6% a year earlier indicates that part of the recent step up in quarterly profit reflects the absence of that charge. Bullish investors may want to separate that effect from any underlying margin improvement.

Asset quality: non performing loans at US$21.4 million

• Non performing loans were US$21.4 million at Q1 2026 compared with US$16.1 million at Q4 2025 and US$14.1 million at Q2 2025, while total loans over the same points moved between US$3,807.9 million and US$3,920.6 million.
• Critics taking a more bearish angle often focus on credit risk for regional banks, and the movement in these figures feeds into that view, because non performing loans are higher than at several points in 2025 even as total loans have eased back from US$4,022.2 million in Q4 2024 to US$3,807.9 million in Q1 2026.
  • Bears point out that the large one off loss of US$42.7 million in the last 12 months coincides with this pattern in non performing loans, and trailing 12 month net income of US$4.8 million at Q1 2026 is far below the US$29.9 million level a year earlier.
  • That combination feeds into concerns about how much earnings capacity is available to absorb any further credit costs, especially when the stock already carries an elevated P/E of 123x against industry averages around 11x.

High valuation versus earnings and dividend coverage

• The stock trades at about US$14.03 compared with a stated DCF fair value of roughly US$3.67. The P/E of 123x sits far above peer and US banks industry averages of around 11x, and the dividend yield of 3.71% is flagged as not clearly covered by current earnings.
• For a bearish narrative, what is striking is how these valuation and payout metrics intersect with the recent profit record, in particular trailing 12 month net margin of 3.1% versus 24.6% a year earlier and trailing basic EPS of roughly US$0.12 at Q1 2026. Together, these figures challenge the idea that the current share price and dividend level are comfortably supported by recent fundamentals.
  • Skeptics highlight that the share price of US$14.03 sits well above both the DCF fair value reference of US$3.67 and an analyst price target of US$14.50, while trailing 12 month revenue of US$154.8 million is paired with only US$4.8 million of net income.
  • The same investors also note that dividend coverage looks thin when the dividend yield is 3.71% and earnings over the last 12 months already reflect the impact of the US$42.7 million one off loss, which leaves limited room if profitability stays closer to the recent 3.1% net margin than to the prior 24.6% level.
