EXHIBIT 99.1 NEWS RELEASE [WILLIAMS LOGO] NYSE: WEG - -------------------------------------------------------------------------------- DATE: April 25, 2002 CONTACT: Kelly Swan Paula Farrell Media Relations Investor Relations (918) 573-6932 (918) 573-9233 kelly.swan@williams.com paula.farrell@williams.com WILLIAMS ENERGY PARTNERS REPORTS INCREASE IN FIRST-QUARTER EARNINGS TULSA, Okla. - Williams Energy Partners L.P. (NYSE:WEG) today reported earnings for the first quarter ending March 31, 2002. Net income for the most recent quarter was $8.5 million, or 72 cents per unit on a fully diluted basis, compared with $3.9 million in the 2001 quarter. The $4.6 million increase in net income was principally due to significantly higher ammonia pipeline shipments and the acquisition of two inland terminals in Little Rock, Ark., in June 2001 and a marine facility in Gibson, La., last October. The partnership also generated additional earnings this year from the Aux Sable natural gas liquids pipeline acquisition that occurred in December 2001 and initiation of service to Southwest Airlines at Dallas Love Field. Changes related to the partnership's initial public offering in February 2001 also contributed to higher 2002 earnings, including the retirement of debt that lowered interest costs and the lack of income taxes because of the partnership structure. Interest costs further decreased because of a lower interest rate environment in the 2002 quarter. Prior to the initial public offering, the assets were held by Williams (NYSE:WMB). "Our earnings have directly benefited from our active pursuit of acquisitions that increase our distributable cash flow. This activity has helped increase our distribution growth by almost 17 percent over the past four quarters," said Phil Wright, president. "Looking ahead, we expect earnings and cash flow for the second quarter to continue to grow at a healthy rate as we begin to realize the results expected from Williams Pipe Line, which we acquired this month," Wright added. Operating profit for the first quarter increased $2.7 million from $6.8 million in 2001 to $9.5 million in 2002. The increase was primarily due to higher ammonia volumes and the operating results of the Gibson and Little Rock terminals.
