CEO Jacob Thaysen bought 12,350 shares of ILMN for $998,674.44 across 7 transactions on May 12–13, 2025.
Thaysen Jacob, CEO of Illumina, acquired 12,350 shares totaling $998,674.44 across 7 separate purchases on May 12–13, 2025, at a blended average price of $80.86, increasing his stake from 71,040 to 83,390 shares (+17.4%). The transaction occurred while the stock trades at $78.21, down 49.6% from its 52-week high of $155.15, and Illumina reports full-year unprofitability and negative 2.9% annual revenue growth, suggesting the company faces headwinds. Notably, Thaysen's prior open-market buy activity at ILMN shows no measurable timing success: three prior buys in February 2024 each yielded negative 90-day returns (ranging from -20.4% to -21.7%), and his cross-ticker track record (3 prior buys) posted a 0.00% 90-day win rate with an average 90-day return of -21.0%, indicating a pattern of ill-timed acquisitions. The current purchase, transacted well above today's market price and into a period of weakness, warrants examination of its timing and strategic intent against the backdrop of the company's operational challenges.
