Significance 7/10

CEO Nicholas W Zillges bought 970 shares of MBBC at $15.00; 3 other insiders also bought within 14 days (cluster pattern).

Nicholas W Zillges, President and CEO, purchased 970 shares at $15.00 on 2026-06-16, increasing his holdings from 56,235 shares to 57,205 shares. His cross-ticker track record shows 8 prior buys with a 100.00% 90d win rate and average 90d return of +10.4%. At MBBC specifically, his prior 4 measurable buys all posted positive 90d returns (ranging from +0.6% to +22.2%), establishing a consistent pattern of well-timed accumulation at this ticker. The current stock price of $13.88 is -11.9% from the 52-week high of $15.75, and the filing discloses that 3 other insiders also bought within the past 14 days. This convergence of CEO accumulation against elevated valuation (P/E 37.51) alongside coordinated insider buying warrants attention to the underlying confidence signal.

Significance 7/10

Marathon CEO Nicholas Zillges purchased 1,076 shares over 6 trading days at blended $14.35 avg, adding $15,439.55 to position

Nicholas W Zillges, President and CEO of Marathon Bancorp, executed 6 separate purchases totaling 1,076 shares for $15,439.55 between June 3–10, 2026, at prices ranging from $13.75 to $14.75 and a blended average of $14.35. This increased his holdings from 50.1K to 51.2K shares (+2.1%). The purchases occurred while the stock traded near the lower end of its 52-week range ($9.90–$15.75), currently at $14.30 and down 5.5% over 30 days despite a +3.1% 90-day gain. His track record across tickers shows 8 prior open-market buys with a 100.00% 90-day win rate (avg +10.4% return), and at Marathon specifically, 4 of 4 prior measurable buys were well-timed at the 90-day mark, most recently delivering +16.9% (November 2025) and +22.2% (November 2025). The pattern of consistent accumulation at favorable entry points, combined with a demonstrated ability to execute well-timed trades at this ticker, suggests conviction in the company's near-term prospects.

Significance 5/10

CEO Nicholas Zillges buys 1,075 shares of Marathon Bancorp at $11.37 on 2025-11-26; stock -27.8% from 52-week high.

CEO Zillges purchased 1,075 shares at $11.37, increasing his holdings by 1,075 shares to 34,803 shares total. The stock is trading at $11.15 (current price), down 27.8% from its 52-week high of $15.44, while the stock is up 3.0% over 30 days and 7.9% over 90 days. His cross-ticker track record shows 7 prior buys with a 100.00% win rate at the 90-day mark, though this specific ticker shows mixed recent timing: his last two measurable same-ticker purchases (2025-06-13 and 2025-05-16) returned +2.1% and +0.6% respectively over 90 days. The transaction reflects continued accumulation at a depressed price level relative to the year's peak, though market capitalization of $32.8M and a P/E of 101.36 suggest a small-cap profile with elevated valuation metrics.

Significance 5/10

Marathon Bancorp President Zillges buys 1,325 shares at $11.00; holds 33,728 post-trade as stock down 29.7% from 52-week high.

Nicholas W. Zillges, President and CEO, purchased 1,325 shares at $11.00 on 2025-11-13, increasing his holdings to 33,728 shares. The transaction occurs with the stock trading 29.7% below its 52-week high and -1.3% over the past 30 days. His prior trades at Marathon Bancorp show mixed near-term results (30-day returns of +0.3% and -0.9% on recent buys) but consistently positive 90-day outcomes, with 2 of 2 measurable prior buys at this ticker well-timed at the 90-day horizon. The CEO's continued accumulation despite significant downside from highs and his historical success timing Marathon trades merits investor attention to whether this represents renewed confidence or routine portfolio management given current valuation levels.

Significance 3/10

CEO Nicholas Zillges bought 500 MBBC shares at $9.99; stock -35.4% from 52-week high, company unprofitable full-year.

Nicholas Zillges, President and CEO, purchased 500 shares of Marathon Bancorp at $9.99 on 2025-06-13, increasing his holdings to 33,572 shares (+1.5% net change). The transaction occurs in a challenged environment: MBBC is trading $9.98 currently, down 35.4% from its 52-week high of $15.44, and the company reported negative net income over its most recent full fiscal year despite recent quarterly earnings of $148.4K. This is Zillges's second buy at MBBC in less than one month (he purchased 30 shares on 2025-05-16 which posted a -0.9% 30-day return). Notably, across his cross-ticker open-market trading history, his prior 5 buys averaged a -0.9% 30-day return, and at MBBC specifically, his prior trades show no measurable well-timed outcomes at the 90-day mark. The CEO's repeated buying into a depressed price point paired with structural unprofitability and a pattern of unsuccessful prior timing creates a signal requiring investor scrutiny of underlying business recovery assumptions.

Significance 3/10

Marathon Bancorp CEO Zillges purchases 500 shares at $10.07, adding to 33,072-share position despite stock down 34.8% from 52-week high.

CEO Nicholas W Zillges purchased 500 shares of MBBC at $10.07 on 2025-05-16, increasing his holdings from 32,572 to 33,072 shares. The transaction occurs as the stock trades at $10.07, which is 34.8% below its 52-week high of $15.44 and down 26.0% over the prior 30 days. The company reported a negative full-year net income in its most recent fiscal year, despite showing $148.4K in net income for a recent interim period, resulting in an elevated P/E of 62.94. While the CEO's track record shows 4 prior open-market buys, his same-ticker purchase history at MBBC contains 4 prior trades with outcomes not yet measurable, providing no track record of timing accuracy at this specific security to contextualize this acquisition.
