Sold out (Q1 2026)
From Starboard Value’s Form 13F filing with the SEC, which can be up to 45 days after quarter-end. Covers long US-listed securities only: it excludes short positions, options detail, cash, bonds, and non-US holdings, so it is not the manager’s complete portfolio, and share counts and values are as of Q1 2026, not today. Not investment advice.
