NEW YORK — Board members and executives of Valero Energy Corp. (NYSE: VLO) visited the New York Stock Exchange on July 14 to celebrate the company’s 25th anniversary of listing on the NYSE. The company listed on January 2, 1980.

To celebrate this occasion, Chairman and CEO Bill Greehey rang The Closing Bell.

Over the past 25 years, Valero has achieved record-breaking success, growing from a regional energy company with one refinery and 170,000 barrels per day (BPD) of capacity, to the 22nd largest company among the Fortune 500 with 14 plants that have 2.5 million BPD of capacity and a network of more than 4,700 retail and branded wholesale outlets in the U.S., Canada and the Caribbean. Its aggressive growth is continuing as Valero is poised to become the largest refiner in North America when it completes its acquisition of Premcor Inc. (NYSE: PCO) later this year, and the company’s well on its way to becoming a household name as it converts all of its retail sites to the Valero brand. As a result of its earnings performance, Valero has had a total shareholder return of 87 percent versus the S&P 500 Index’s 1.6 percent return so far this year, making it the top-performer in the S&P. What’s more, the San Antonio based company was named Forbes Magazine’s 2004 Best Big Company, recognized as the 2004 Oil Company of the Year at the Platt’s Global Energy Awards, and honored with United Way’s Spirit of America award for the second time.
