  • Footnotes: F1 = weighted average price; F2 notes controlling principals (David M. Greenhouse and Adam C. Stettner) and that AWM disclaims beneficial ownership except for pecuniary interest; F3 lists the funds for which AWM is adviser and the breakdown of shares.

Context
This filing is from an investment adviser/10% holder managing fund positions, not an individual officer or director. Such sales most often reflect portfolio rebalancing or fund-level liquidity needs rather than executive sentiment. The report is informational and does not state motives for the disposals.
