Magellan Midstream Partners Announces Record Quarterly Financial Results

Generates 34% Higher Income Excluding One-Time Gain in 2008

TULSA, Okla. – Magellan Midstream Partners, L.P. (NYSE: MMP) today reported record quarterly operating profit, net income and net income per limited partner unit.

First-quarter 2008 operating profit of $105.3 million represented a 63% increase compared to $64.7 million for first quarter 2007. Net income grew to $93.3 million during first quarter 2008, which is an 88% increase over the $49.7 million reported for first quarter 2007.

Excluding a $26.5 million one-time gain on assignment of a third-party supply agreement during March 2008, the partnership generated 22% higher operating profit and 34% more net income in first quarter 2008 compared to the same period in 2007.

“We kicked off 2008 with a strong first quarter, bolstered by higher financial results from each of our business segments,” said Don Wellendorf, chief executive officer. “Magellan continues to focus on delivering solid base business performance while generating additional opportunities for future growth.”

An analysis of variances by segment comparing first quarter 2008 to first quarter 2007 is provided below based on operating margin, a financial measure that reflects operating profit before affiliate general and administrative (G&A) expense and depreciation and amortization:

Petroleum products pipeline system. Pipeline operating margin was $109.4 million, an increase of $31.3 million and a quarterly record for this segment. Transportation and terminals revenues slightly decreased between periods due to 3% lower shipments, primarily offset by higher fees earned for leased storage and ethanol blending services. Operating expenses declined due to lower property taxes and more favorable net product overages, which reduce operating expenses, partially offset by increased maintenance expense. Product margin increased primarily due to higher commodity prices, which resulted in improved fractionation margins.

First quarter 2008 further benefited from a $26.5 million gain on assignment of a third-party supply agreement during March 2008. Magellan had recorded a liability upon assumption of this agreement as part of a pipeline acquisition in late 2004. The agreement had obligated the partnership to sell petroleum products to one of its customers. Due to the recent assignment of this agreement to another company, the partnership reduced the remaining liability to zero, resulting in a gain during first quarter 2008.

Petroleum products terminals. Terminals operating margin was $26.8 million, an increase of $7.3 million and a quarterly record for this segment. The current period benefited from increased revenues due to expansion projects

at the partnership’s marine terminals and higher additive fees at its inland terminals, which more than offset lower inland throughput volumes. Operating expenses decreased primarily due to gains recognized from insurance proceeds received in 2008 for historical hurricane damage and product downgrade charges that had negatively affected the 2007 period due to the accidental blending of a small amount of product in first quarter 2007. These favorable items were partially offset by higher 2008 expenses related to maintenance and personnel costs. Product margin increased between periods due to the sale of additional product overages in the terminals segment.

Ammonia pipeline system. Ammonia operating margin was $3.2 million, an increase of $3.8 million. Revenues increased between periods due to higher average tariff rates and additional shipments. Operating expenses declined primarily due to lower maintenance and environmental expenses in the 2008 period.

Depreciation and amortization increased due to recent capital spending, while net interest expense decreased in the current quarter as a result of lower interest rates.

Basic and diluted net income per limited partner unit was 89 cents for first quarter 2008 and 55 cents for first quarter 2007. The gain on assignment of the third-party supply agreement resulted in a favorable impact to 2008 net income per unit of 20 cents, after considering the corresponding change in income allocation between the partnership’s limited partners and general partner.

Distributable cash flow, which represents the amount of cash generated during the period that is available to pay distributions, grew 23% to $76.3 million during first quarter 2008 from $61.8 million for the corresponding 2007 quarter.

Reflecting financial results to date and expectations for the remainder of 2008, management is increasing its 2008 net income per unit guidance to approximately $3.03, with a second-quarter 2008 estimate of 66 cents.

Management remains committed to its stated goal of increasing distributions by 8% to 10% per year through 2010.

The partnership continues to project that the large majority of its operating margin in 2008 will be generated by its fee-based operations. Including results to date and outlook for the remainder of 2008, management currently expects product margin to account for about 15% of total operating margin based on continuation of high petroleum prices. Future product margin is expected to include results from the partnership’s petroleum products blending operation, transmix fractionation and terminals product overages. As previously noted, management develops distribution growth targets based on the expectation that product-margin related activities will generate about 10% or less of the partnership’s annual operating margin beyond 2008.

Management remains focused on developing growth opportunities for the partnership. Based on the progress of expansion projects already underway, the partnership expects to spend approximately $250 million of growth capital during 2008, with an additional $20 million thereafter to complete these projects. The 2008 estimate includes $10 million the partnership plans to spend to acquire a petroleum products terminal already connected to its pipeline system in Wrenshall, Minnesota, which is expected to close by Aug. 1 subject to regulatory approval. The partnership continues to analyze other potential acquisitions and more than $500 million of potential growth projects in earlier stages of development, which have been excluded from these spending estimates.

Management believes that investors benefit from having access to the same financial measures utilized by the partnership. As a result, this news release and supporting schedules include the non-generally accepted accounting principles measures of operating margin and distributable cash flow, which are important performance measures used by management to evaluate the economic success of the partnership’s operations. Operating margin reflects operating profit before G&A expense and depreciation and amortization, and distributable cash flow is an indicator of the cash available to pay distributions. Reconciliations of operating margin to operating profit and distributable cash flow to net income accompany this news release.

(a) For periods when the distributions the partnership pays exceed its net income, the general partner’s percentage share of income is its proportion of cash distributions paid for the period. For periods when net income exceeds the cash distributions the partnership pays, the general partner’s percentage share of income is its proportion of theoretical distributions that equal net income (before direct charges to general partner). The partnership’s distributions for the three months ended March 31, 2007 exceeded net income for that period; therefore, the general partner’s share of net income was based on its share of cash distributions paid for that period. The partnership’s net income for the three months ended March 31, 2008 exceeded the cash distributions the partnership will pay for that period; therefore, the general partner’s share of income was allocated based on a theoretical distribution of $0.8933 per limited partner unit, at which rate the partnership’s distributions would be equal to its net income (before direct charges to general partner).
