Vectren Corporation was a Fortune 1000 energy holding company headquartered in Evansville, Indiana.

Vectren's non-utility subsidiaries and affiliates offered energy-related products and services to customers throughout the Midwest and Southeast.

The two utilities' holding companies, Indiana Energy and SIGCORP, announced plans to merge in June 1999, and received final approval on March 9, 2000.

In the fall of 2000, Vectren also acquired the natural gas distribution assets of Dayton Power and Light in western Ohio.

As a result of adjustments related to gas and employee benefit costs, 2001 earnings previously reported were reduced by 18 cents per share.
