Eli Lilly & Company is looking to expand its operations with a Terre Haute manufacturer.  The company's animal health division, Elanco, is in the process of acquiring ChemGen in Terre Haute.  The South First Street business employs 24 area workers and, although details of the acquisition have yet to released, it has been noted that Elanco has no intentions of changing ChemGen’s current operations. The deal is set to be completed before the end of the quarter.
