The FTC intervened in Hexion LLC's proposed acquisition of Huntsman Corp., issuing a consent order which requires the divestiture of Hexion's specialty epoxy business, and prevents the sharing of sensitive and non-public information which could lead to coordination of prices. Huntsman and Hexion are producers of high-performance and specialty chemicals used in the aerospace and alternative energy industries. Subsequently, Hexion LLC and Huntsman Corporation petitioned the Commission to reopen and set aside two orders related to their proposed merger because they terminated their planned merger and withdrew their premerger notification filings. Following a public comment period, the Commission has granted, in part, a petition by Hexion LLC and Huntsman Corporation requesting that two FTC Orders related to their proposed merger be reopened and set aside. The agency determined that the firms have satisfactorily shown that changed conditions require that the matter be reopened. In particular, the firms have abandoned the acquisition that the Orders were intended to remedy. In its decision, the Commission set aside the Asset Maintenance Order in its entirety, as well as the Decision and Order regarding Huntsman.
