BONNEY MICHAEL W

Director Bonney sells 11,250 ALNY shares at $450.00 for $5.1M; holds 16.8K post-trade at 52-week high.

On 2025-08-18, Director Michael W. Bonney sold 11,250 shares (representing -40.1% of his pre-transaction holdings of 28,054 shares) at $450.00 per share for a total value of $5,062,500.00. The sale occurred at the 52-week high of $458.28, with the stock at +0.0% from its 52-week peak and +43.0% over the prior 30 days. Bonney's prior five trades in ALNY all occurred on 2025-05-15; four of those sales showed positive 90-day returns (+52.4%, +58.0%, +56.9%, +56.0%), with all five exhibiting gains at the 30-day mark, yet none were well-timed on a 90-day basis (no negative 90-day returns to indicate a decline after sale). His cross-ticker track record across 20 prior sells shows an average 90-day return of +34.7% with a 30.00% well-timed rate, suggesting his historical sells have often preceded further appreciation rather than declines. The company posted $773.7M in quarterly revenue with +23.0% annual growth but remains unprofitable with net income of $-66.3M; the market cap is $60.1B. The transaction reduces Bonney's exposure meaningfully while the stock trades near all-time highs, yet the pattern of his prior ALNY sales—all showing gains afterward—provides no historical basis for interpreting this sale as prescient regarding imminent weakness.

Alnylam Director Bonney sold 11,250 shares for $3,124,216.94 in 14 separate transactions on 2025-05-15.

Director Michael W. Bonney executed 14 separate sales totaling 11,250 shares for $3,124,216.94 on 2025-05-15, reducing his holdings by 40.1% from 28,054 to 16,804 shares. The blended average transaction price of $277.71 sits near the current price of $291.86, with the stock up 24.4% over the past 30 days and approaching its 52-week high of $300.55. Notably, Bonney's prior 5 trades at Alnylam were all well-timed at the 90-day mark, establishing a consistent pattern of selling ahead of subsequent declines, though his cross-ticker track record shows a 90d well-timed rate of 100.00%. The company remains unprofitable (net income of $-57,479,000.00 in the latest quarter) despite strong 23.0% annual revenue growth, creating a divergence between operational momentum and financial performance that may inform the timing of a substantial director-level position reduction.
