On August 19–21, 2026, Keith A. Meister, as controlling person of Corvex Management LP, reported a series of open‑market sales of Illumina, Inc. common stock on behalf of Corvex-managed funds, totaling approximately 716,000 shares at weighted-average prices generally between about $202 and $220 per share, for aggregate proceeds of roughly $150–$160 million. These trades reduced the funds’ direct holdings from 2,069,541 shares to 1,409,851 shares, while Meister and Corvex formally disclaim beneficial ownership beyond their pecuniary interest. The transactions appear to be sizable portfolio sales by an activist shareholder rather than routine compensation-related activity, and the remaining position is still significant in value at current transaction prices.
