Business: Crown Holdings is a worldwide leader in the design, manufacture and sale of packaging products for consumer goods and industrial products. Activist Commentary: Carl Icahn is the grandfather of shareholder activism and a true pioneer of the strategy. The opportunity to create shareholder value here is relatively simple: sell non-core businesses, buy back shares and focus on the pure-play beverage business. The company announced its acquisition of Signode, a transit packaging business, for $3.9 billion in 2017, and might be reluctant to sell it for less than that now. There is more value in how they use those proceeds (i.e., buying back stock in an undervalued, growing business).
