GCBC insider makes substantial multi-tranche open-market purchases totaling over $100k, accumulating shares near recent lows.

An insider at Greene County Bancorp executed three significant open-market purchases over two days, acquiring over 4,000 shares for approximately $100,000—a substantial personal commitment. The purchases occurred when the stock was trading slightly below its recent high, following a sharp rally over the prior month, suggesting the insider is adding to holdings even after a meaningful recovery. The company is profitable with growing revenue and trades at a reasonable valuation multiple, indicating the insider is buying into a financially sound regional bank rather than a distressed situation. This accumulation pattern—multiple tranches within consecutive days—signals conviction and is particularly noteworthy given the consistency of the buy prices, which suggests deliberate and planned execution rather than reactive trading. The size and concentration of these purchases relative to the insider's existing holdings indicate significant confidence in the company's prospects.

Director Hada Tejraj S bought 6,000 shares for $131,780.00; post-transaction holdings 35,427 shares. Cluster buy signal.

Hada Tejraj S (Director) executed 2 separate purchases totaling 6,000 shares for $131,780.00 at a blended average price of $21.96, increasing holdings by 20.4% from 29,427 to 35,427 shares. His prior 5 trades at GCBC were all well-timed buys with positive 90-day returns, and his cross-ticker track record shows 13 prior buys with a 69.23% 90-day win rate and average +8.9% 90-day return. The current price is $21.75, near his transaction prices but within recent downtrend context (stock is down 8.5% over 30 days and 12.0% over 90 days from recent peaks). A cluster buy pattern is present with 2 other insiders also purchasing within the past 14 days, suggesting coordinated conviction at this price level. Fundamentals remain solid: P/E 10.12, revenue growth +11.1%, and net income $10.3M support the valuation range where this insider is adding exposure.

Director Peter W. Hogan bought 3,000 shares of GCBC at $22.10; cluster buy pattern with 2 other insiders in past 14 days.

Peter W. Hogan, a director of Greene County Bancorp Inc, purchased 3,000 shares at $22.10 on March 18, 2026, increasing his holding by 4.2% to 75,000 shares total. This transaction is part of a cluster buy pattern in which 2 other insiders also purchased shares within the past 14 days, suggesting aligned activity among the company's leadership. The timing occurs as the stock trades at $21.75, down 15.5% from its 52-week high of $25.75 and down 8.5% over 30 days, while the company reports solid fundamentals with a P/E of 10.12, net income of $10,292,000.00, and annual revenue growth of 11.1%. Multiple directors accumulating shares contemporaneously during a period of recent price weakness warrants investor attention as a data point in understanding insider perspective on valuation.

GCBC CFO Barzee purchased 1,280 shares at $22.55; stock now $22.22, down 16.0% from 52-week high.

Nick Barzee, SVP and CFO, acquired 1,280 shares of Greene County Bancorp at $22.55, expanding his holdings by +39.5% from 3,240 to 4,520 shares. The stock is currently trading at $22.22, down 16.0% from its 52-week high of $26.46 and down 7.6% over the past 30 days. At his prior GCBC purchases (2025-04-25, 2025-01-31, 2024-10-25), his 90-day outcomes were mixed at +15.9%, -16.7%, and -8.8%, with only 1 of 3 purchases showing positive 90-day returns—suggesting modest predictive accuracy in timing this particular stock. The company reports solid fundamentals: $10.3M net income, +11.1% annual revenue growth, and a P/E of 10.33, though the recent price action indicates broader market or sector headwinds. This purchase occurs as the stock sits near recent lows, but the insider's historical record at this ticker provides limited evidence of strong conviction timing.

Director Cannucciari buys 1,300 GCBC shares at $22.05; holdings rise 42.2% to 4,378 shares amid 11.1% revenue growth and 10.47 P/E.

Christopher Cannucciari purchased 1,300 shares at $22.05 on 2026-03-02, increasing his position by 42.2% to 4,378 shares post-transaction. The company exhibits solid fundamentals: $10,292,000 net income and annual revenue growth of 11.1%, coupled with a low P/E of 10.47. However, context is mixed: the current price of $22.52 is -15.3% from the 52-week high of $26.60, and Cannucciari's prior five trades at GCBC show inconsistent timing, with 3 of 5 buys well-timed at the 90-day mark but the most recent buys in late October 2025 yielding flat and negative 30-day and 90-day returns. The stock's 30-day change of -3.9% and 90-day change of -2.1% suggest recent weakness, though the purchase occurs at near-low levels relative to the 52-week range of $20.74–$26.60.

Director Hada Tejraj S bought 1,000 shares of GCBC at $21.95; 5 recent buys in 16 days show concentrated activity.

Hada Tejraj S purchased 1,000 shares at $21.95 on 2005-11-20, expanding holdings to 29,191 shares (+3.5% from prior level). The transaction occurs within a window of five buys at GCBC spanning from 2025-11-03 to 2025-11-18—all within a 16-day period—suggesting either liquidity management or response to a perceived opportunity. Current price sits at $22.04, near the transaction price, while the stock trades 31.0% below its 52-week high of $31.93. The company shows solid fundamentals with P/E of 11.13, net income of $8,870,000.00, and annual revenue growth of +11.1%, though the stock has declined 8.0% over 90 days. No material operational changes or valuation pivots are evident from the filing; the concentration of purchases within two weeks merits review to determine whether they reflect scheduled activity or discretionary positioning.

EVP/CLO Antalek John purchases 1,500 shares of GCBC at $22.00; position grows 24.7% to 7,567 shares

Antalek John, Executive Vice President and Chief Legal Officer, purchased 1,500 shares at $22.00, increasing his holdings by 24.7% to 7,567 shares for a total transaction value of $33,000.00. The purchase occurs while the stock trades 35.3% below its 52-week high of $34.11, near the lower end of the annual range. The company exhibits solid fundamentals with net income of $8,870,000.00 and annual revenue growth of 11.1%, supported by a P/E of 11.15 and market cap of $375,952,362.24. This insider acquisition by a senior legal officer—a routine governance role less frequently associated with forward-looking investments—occurs during a period of relative weakness; the stock is down 4.2% over the past 90 days and 1.6% over 30 days.

Director Tejraj buys 3,000 GCBC shares at $21.96; fourth consecutive purchase in 15 days, stock -35.3% from 52-week high.

Tejraj purchased 3,000 shares at $21.96 on 2025-11-18, the fourth buy executed in just 15 days (prior buys on 2025-11-14, 2025-11-05, 2025-11-04, and 2025-11-03). The concentrated buying pattern coincides with the stock trading at $22.08, which represents -35.3% from its 52-week high of $34.11. On his cross-ticker track record, Tejraj's prior 12 buys averaged +4.2% 30-day returns and +9.8% 90-day returns with a 50% win rate; however, his same-ticker history at GCBC shows one measurable outcome (May 2025 purchase: -6.3% at 30 days, +7.7% at 90 days), and four recent purchases remain unmeasured. Fundamentals appear stable: the company reports $8.9M net income, +11.1% annual revenue growth, an 11.15 P/E, and $376.0M market cap. The rapid succession of open-market purchases into a depressed valuation warrants monitoring of whether this pattern reflects management confidence in the discount or other strategic considerations.

Significance 5

Director Tejraj bought 366 GCBC shares at $22.00 on 2025-11-14; stock now $21.68, down 37% from 52-week high.

Hada Tejraj S, a director at Greene County Bancorp, purchased 366 shares at $22.00, bringing total holdings to 24,923 shares. The transaction occurred as GCBC trades at $21.68, representing a 37.0% decline from the 52-week high of $34.39 and an 8.4% drop over the past 90 days. At the same-ticker level, Tejraj's two prior measurable buys at GCBC (May 2025) both generated positive 90-day returns (+7.7% and +6.8%), suggesting a pattern of timing purchases favorably. However, the recent three consecutive buy dates (November 3–5, immediately preceding this transaction) remain unmeasurable, and this latest purchase on November 14 coincides with elevated price pressure. The company's fundamentals remain solid with net income of $8,870,000.00, annual revenue growth of +11.1%, and a P/E of 10.95, warranting deeper examination of whether the stock's recent weakness reflects a temporary dislocation or material deterioration in outlook.

Director Tejraj purchases 1,545 shares in 2 transactions at $22.20–$22.52; 3 other insiders bought within 14 days

Hada Tejraj S, a director of GREENE COUNTY BANCORP INC, made 2 separate purchases totaling 1,545 shares for $34,779.00 at a blended average price of $22.51 on 2025-11-04 and 2025-11-05, increasing his holdings by 6.7% to 24,557 shares. The stock currently trades at $22.36, down 36.1% from its 52-week high of $34.97, and the company reports solid fundamentals including annual revenue growth of +11.1% and a P/E of 10.91. Notably, 3 other insiders also purchased shares within the past 14 days, creating a cluster buy pattern that may suggest management's assessment of relative value at current prices. Tejraj's cross-ticker track record shows a 50% win rate at the 90-day mark with an average 90-day return of +9.8%, while his same-ticker history at GCBC reveals 2 of 4 prior measurable buys were well-timed at the 90-day mark, though outcomes here remain mixed.
