Activist filings

Estimated cost = total acquisition funds ÷ shares held, from the latest report (or the previous one if the latest does not state the funds). Trades after the report's base date are not included. Stakes whose reports give no funding figure are left out. Share splits after the report are adjusted using the change in shares outstanding. Costs outside the stock's price range while held (0.8x the monthly low to 1.2x the high) are treated as reporting quirks (e.g. funds not updated after selling) and not shown. Stakes cut below 5% (mostly sold) are left out of the totals.

This site ranks listed companies by how closely their public filings (annual reports and large-shareholding reports) resemble past tender-offer and MBO targets. It is not a prediction that any company will be bought, is not based on any non-public information, and is not a recommendation to buy or sell. Not investment advice.
