JANA Partners Management, LP: trading record in brief
JANA Partners Management, LP discloses dealings in 5 companies, chiefly Mercury Systems Inc, Lamb Weston Holdings, Inc. and TreeHouse Foods, Inc. In total, 30 filings cover trades dated from 8 November 2023 to 15 April 2026.
In open-market terms, that means 14 purchases worth €75.3M on one side and 6 sales worth €196.1M on the other. Taken together, the sales exceed the purchases by €120.7M. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Outside the open market, there are 6 share grants and 3 option exercises. In 2026 alone, the filings show 4 purchases and 3 sales.
The median purchase comes to €3.0M. Of 14 purchases, 12 formed part of a group of insiders buying within 30 days of each other. Purchases made close together by different insiders form what is called a cluster. Looking at 10 purchases old enough to measure, the stock rose over the following 90 days in 50% of cases; the median change was -2.2%. Past outcomes like these are no guarantee of what comes next.
The newest entry dates from 15 April 2026: an open-market purchase of €3.6M, in Lamb Weston Holdings, Inc. Between a trade and the moment it shows up on SEC (Form 4), the median delay is 2 days. US insiders must file a Form 4 within two business days of a trade. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
