• Total shares sold: 375,941. Total proceeds: ~$85,241,664.
• Ownership after transaction: Not specified in the excerpt of the filing provided.
• Footnotes: F1/F2 — these shares are held for accounts of Corvex private funds (Corvex is the adviser); Meister controls Corvex’s general partner and disclaims beneficial ownership except for any pecuniary interest. Several footnotes (F3–F15) note that reported prices are weighted averages across multiple trades within specified price ranges.

Context

• These were outright sales (code “S”) of fund-held stock rather than personal purchases; the filing and footnotes show the transactions relate to Corvex-managed funds for which Meister’s firm is adviser. Institutional fund sales by a director/adviser are not the same as an executive personally selling company stock.
• No inference about Meister’s personal view on Illumina’s prospects should be drawn from the sale alone; the filing documents execution and fund/ownership relationships but does not state motivation.
