Meister Keith A.

Meister Keith A. has filed 142 Form 4 transactions across four companies, with a clear and sustained bias toward selling. Total open-market sales reached $619.2 million, against $80.9 million in open-market purchases. The most recent activity, all in Illumina (ILMN), consists of 25 sales between August 25 and September 4, 2026, with no purchases in that window. The recent ILMN sales are large and clustered. On September 4 alone, Meister reported three sales worth roughly $26.1 million combined, including a single transaction of $21.98 million. The prior two days added another $17.4 million. The pattern extends back through late August, with multiple sales on August 25, 26, and 27 totaling more than $70 million. Individual transaction sizes range from under $10,000 to over $20 million, but the bulk are in the $1 million to $12 million range. Over the full filing history, Meister has also acquired $38.3 million in shares through grants and option exercises, which are compensation and mechanical events rather than discretionary purchases. The only code showing conviction, open-market buying, is dwarfed by selling. The direction is consistent: heavy, repeated sales in ILMN with no recent buying in any ticker.
