B/E Aerospace Inc. fell as much as 5.7 percent after announcing plans to split into two companies rather than auction assets in response to pressure from an activist shareholder.

The pair will be independent, publicly traded entities, with their own management team and boards, with one focused on aircraft interiors and the other on distribution, logistics and technical services. The company will continue to review further strategic options that could include a sale, co-chief executive officer Amin Khoury said on a conference call with analysts.
