Higher Net Interest Margin Supports Greene County Bancorp Profits

• Net interest margin for FY 2026 moved from 2.79% in Q1 to 3.15% in Q4, while the trailing twelve month net profit margin stood at 45.3% compared with 42.4% a year earlier.
• What supports a more bullish interpretation is that higher margins are showing up alongside EPS moving from US$0.52 in Q1 FY 2026 to US$0.67 by Q4. This strongly backs the idea that Greene County Bancorp is converting its loan book and rate environment into thicker profitability rather than relying only on revenue growth.
  • Trailing twelve month net income reached US$41.0 million versus US$31.1 million a year earlier, which aligns with the bullish focus on stronger earnings power.
  • The five year annualized earnings growth rate of 6.3% sits well below the latest 31.7% year over year earnings growth, so bulls are leaning on a much stronger recent period than the longer run history.

Cost Efficiency and Credit Quality Trade Off

• The cost to income ratio on a trailing twelve month basis was 47.73% at FY 2026 Q4 compared with 52.25% at FY 2025 Q4, while non performing loans at Q4 FY 2026 were US$3.9 million against US$3.1 million a year earlier.
• Critics with a more bearish tilt may point out that better cost efficiency is arriving alongside higher reported non performing loans, so the quality of that profitability is worth watching rather than assuming it is risk free.
  • Operating leverage looks favorable with revenue over the trailing twelve months rising from US$73.4 million at FY 2025 Q4 to US$90.5 million by FY 2026 Q4. Over the same period, non performing loans edged from US$3.06 million on a trailing basis at FY 2025 Q4 to at least US$3.07 million by FY 2026 Q3 and US$3.9 million at the point in time in FY 2026 Q4.
  • That mix of a higher net profit margin at 45.3% and a slightly larger pool of problem loans gives bears a concrete area to watch on credit risk even as headline profitability looks strong.

Premium P/E and Modest DCF Gap

• Greene County Bancorp trades on a trailing P/E of 13.7x compared with peers at 11.5x and the US Banks industry at 12.1x, while the US$33 share price sits about 3.6% below a DCF fair value of US$34.24.
• Consensus style thinking that the stock is priced for quality finds some support here, because the premium P/E and only small discount to DCF fair value both suggest investors are already paying up for the recent 31.7% earnings growth and 45.3% net profit margin rather than treating GCBC as a deep value situation.
  • The modest price gap to DCF fair value is far smaller than the difference between the latest year over year earnings growth rate and the 6.3% five year annualized pace, so the market is not assigning a large valuation cushion to that stronger recent period.
  • At the same time, the absence of substantial insider selling over the past three months removes one common bearish talking point, which leaves valuation metrics and profit durability as the main focus for both sides of the debate.
