LexCorp was a group of multinational corporations owned and controlled by Lex Luthor.
LexCorp was headquartered in Metropolis, and military contracts seem to be one of the company's main foci. LexCorp military technologies have included the Lexo-Skel Suit 5000, and another prototype battlesuit, eventually used by the hero Steel.
Luthor was eventually caught and convicted for his numerous criminal activities. During his incarceration, LexCorp was headed by Mercy Graves. Mercy took a more cavalier approach to management, pointedly ignoring Luthor's style and laying off employees (such as Professor Ivo) to save money; by the next time she and Luthor met, she had managed to raise the stock 38%. After he was pardoned by the President during the Justice Lords incident, Luthor regained control of LexCorp. Lexcorp's status following Luthor's arrest after the Cadmus Crisis is unknown.
