Contran is a U.S.-based holding company that holds stakes in several subsidiaries, with its largest holding in Valhi, Inc., a publicly traded firm that Contran controls to about 93%. Through Valhi, Contran participates in diversified businesses spanning chemicals (NL Industries and Kronos Worldwide), waste management (Waste Control Specialists), and security-related products and components (CompX International). Keystone Consolidated Industries is a wholly owned subsidiary that manufactures fencing and wire products, and the group is governed by the family of the late chairman Harold Simmons. Contran operates as a holding company whose value derives from its stakes in subsidiaries rather than from direct manufacturing activity. The company is mid-sized and based in the United States. In April 2026, Valhi appointed Randy L. Hill to fill a board vacancy after the death of a director.
