EXHIBIT 99 (WILLIAMS ENERGY PARTNERS LOGO) NEWS RELEASE NYSE: WEG ================================================================================ DATE: April 28, 2003 CONTACT: Susie Hereden Paula Farrell Media Relations Investor Relations (918) 573-2278 (918) 573-9233 susie.hereden@williams.com paula.farrell@williams.com WILLIAMS ENERGY PARTNERS REPORTS 32 PERCENT PROFIT GROWTH TULSA, Okla. - Williams Energy Partners L.P. (NYSE:WEG) today announced first-quarter 2003 operating profit of $38.1 million compared with $28.8 million in 2002, representing a 32 percent increase. Net income for the same period increased 38 percent from $21.1 million in 2002 to $29.1 million in 2003. Improved results from the partnership's Williams Pipe Line system and independent petroleum products terminals contributed to the growth in operating profit. Williams Pipe Line generated additional revenues due to higher transportation rates resulting from longer haul shipments, higher ancillary service revenues and increased volumes. The independent terminals benefited from a contract settlement associated with the early termination of an affiliate's storage agreement. Partially offsetting these increases were reduced transportation volumes on the partnership's ammonia pipeline system resulting from high prices for natural gas, the primary component in the production of ammonia. The partnership's general and administrative expenses decreased from first-quarter 2002 primarily due to the establishment of a cap on these expenses negotiated when the partnership acquired Williams Pipe Line. Although the Williams Pipe Line system was acquired April 11, 2002, the acquisition is treated similar to a pooling of interest under accounting rules requiring that historical financial statements be restated to include the results from Williams Pipe Line. The increase in net income was primarily attributable to the higher operating profit. Increased income resulting from the elimination of income taxes due to the partnership structure was offset by increased interest expense associated with the Williams Pipe Line acquisition. Diluted earnings per unit increased to 99 cents for first-quarter 2003 compared with 72 cents for the same period in 2002. Based on accounting rules, per unit numbers are not restated to include Williams Pipe Line results prior to the partnership's ownership. The average number of limited partner units outstanding on a diluted basis was 27.3 million units for first-quarter 2003 compared with 11.4 million units for first-quarter 2002. MORE PAGE 2/2 WILLIAMS ENERGY PARTNERS REPORTS 32 PERCENT PROFIT GROWTH "Our refined products businesses continue to provide outstanding results and the market conditions affecting our ammonia business are improving," said Don Wellendorf, chief executive officer. "We remain focused on the key components of our strategy, which are excellent customer service, safe operations and growth in cash flow through organic opportunities and accretive acquisitions." The partnership announced on April 21 that Williams (NYSE:WMB) has agreed to sell its 54.6 percent interest in Williams Energy Partners to a new entity formed jointly by private equity firms Madison Dearborn Partners, LLC and Carlyle/Riverstone Global Energy and Power Fund II, L.P. Before consideration of the one-time transition expenses associated with the partnership's separation from Williams, management expects earnings per unit for the second quarter to be between 80 and 85 cents. Expectations for second quarter are lower than the same period in 2002 primarily due to a higher weighted average number of units outstanding during 2003 resulting from the second-quarter 2002 equity issuances associated with the financing of the Williams Pipe Line system. After consideration of the one-time transition costs, which will not impact distributable cash generated per unit, management expects earnings per unit between 50 and 55 cents for the second quarter. Management remains comfortable with the annual guidance previously provided for earnings per unit between $3.25 and $3.35 for the full-year 2003. Current analyst expectations for 2003 average $3.30. "Our businesses have continued their outstanding record of exceeding earnings expectations," said John Chandler, chief financial officer. "Because of our strong first-quarter results as well as our expectations for the remainder of the year, our earnings guidance for the year remains unchanged, even after consideration of the one-time expense items associated with the partnership's separation from Williams."
