Two senior insiders buying consistently across multiple days at increasing prices ($14.24-$14.75) signals conviction near current levels. For a micro-cap bank, this pattern often precedes or accompanies improving fundamentals or a catalyst. Monitor the next 10-Q for deposit trends and loan growth.
Price Chart
Executive Summary
Two insiders at MBBC (President/CEO Zillges and EVP/CAO Spatz) have been aggressively buying shares, totaling ~$71K over the past week including today's cluster. The CEO and CAO have purchased on every trading day from June 5-10, a concentrated accumulation pattern. While the dollar amount is modest relative to the $42M market cap (~0.17%), the unanimity, frequency, and C-suite involvement elevate the signal.
Key Financial Metrics
Key Facts

- Today's cluster (2026-06-10) adds 2 buys: CEO bought 170 shares at $14.75 ($2.5K) and CAO bought 602 shares at $14.75 ($8.9K)
- Both insiders have purchased on each trading day the past 4 sessions, an unusually consistent accumulation pattern
- Total insider buying in the last 30 days is 10 buys totaling $58K, nearly all by these two executives
- At a $42M market cap, the ~$71K cluster is ~0.17% of market cap — modest by proportionality but notable for a micro-cap thrift
Financial Impact

Risk Factors
- Micro-cap banks have low liquidity — the insider signal may reflect subjective value rather than near-term catalysts
- $71K is a meaningful fraction of annual salary for insiders at a micro-cap but still modest in absolute terms
