- JANA owns 6.9% and has said it may push for changes. Since Feb 13, 2024.
What this means for you
JANA has told the regulator it may push for changes at this company. That usually means asking for a seat on the board, a sale of the company, or a change in how it is run.
Nothing is required of you now.
Large investors can also sell down and walk away. We show every notice they file, the day it is filed.
