Exhibit 99-1 Vectren to Update Business Strategies Evansville, Indiana - (NYSE:VVC) Today, Vectren Corporation executive management will conduct an analyst conference to discuss expected 2001 results and roll out the Company's business strategies for fiscal year 2002 and beyond. The conference will be broadcast via the Internet at 12:30 p.m. ET. Included in the presentation will be a discussion of expected 2001 results that reflect the impact of the extremely mild weather experienced to date as the 2001-2002 heating season begins. Revised estimates for 2001 are in the range of $1.35-$1.40, before non-recurring items previously disclosed. Management will also provide detailed discussions of business plans for 2002 that are expected to result in earnings per share to be in the range of 75 to 85 cents for the 2002 first quarter and $1.85 to $1.95 for the 2002 fiscal year. These expectations have been reduced slightly from those previously released due to the anticipated impacts from a mild recession. Join the webcast for additional details at www.vectren.com.
