BUCKEYE PARTNERS, L.P. REPORTS 2011 FIRST-QUARTER EARNINGS RESULTS;
INCREASES QUARTERLY CASH DISTRIBUTION

HOUSTON, May 6, 2011 — Buckeye Partners, L.P. (“Buckeye”) (NYSE: BPL) today reported net income attributable to Buckeye’s unitholders for the first quarter of 2011 of $66.5 million, or $0.79 per unit, compared to net income attributable to Buckeye’s unitholders for the first quarter of 2010 of $11.3 million, or $0.56 per unit. The diluted weighted average number of units outstanding in the first quarter of 2011 was 84.0 million compared to 20.0 million in the first quarter of 2010. The increase in the number of units reported for the first quarter of this year versus the first quarter of 2010 was significantly impacted by Buckeye’s merger with Buckeye GP Holdings L.P. in the fourth quarter of 2010, and the issuance of units in connection with the acquisition of Bahamas Oil Refining Company International (“BORCO”) in the first quarter of 2011.

Buckeye’s Adjusted EBITDA (as defined below) for the first quarter of 2011 was $122.2 million compared with Adjusted EBITDA of $89.5 million for the first quarter of 2010. Operating income for the first quarter of 2011 was $92.6 million, an increase of 33.2 percent compared to $69.5 million for the prior year period.

“Buckeye’s overall operating results for the first quarter of 2011 were strong,” stated Forrest E. Wylie, Chairman and CEO. “Adjusted EBITDA, our primary measure of performance, increased by 36.6 percent year over year. Although the primary driver of the increase is attributable to recent acquisitions, we saw a 7.9 percent year over year increase in the Adjusted EBITDA of our Pipelines & Terminals segment, which largely represents organic growth.”

“As the Buckeye organization began celebrating its 125^th anniversary of continuous operations, we successfully closed our largest acquisition to date, BORCO, a premier marine terminal in the Bahamas that increased our total storage capacity to over 53 million barrels,” continued Wylie. “The acquisition allows Buckeye to play an important role in international product flows. In the first quarter, we also announced an agreement with affiliates of BP North America to acquire approximately 1,000 miles of pipeline and 33 liquid petroleum terminals, adding approximately 10 million barrels of storage capacity to our portfolio of assets. We are working to integrate and optimize our recent acquisitions and to continue to identify growth opportunities across our entire system.”

Buckeye’s business segments have been realigned as of the first quarter of 2011 to reflect recent changes in our operations. Buckeye will continue to report results for five business segments, but the former Pipeline Operations segment and the former Terminalling & Storage segment are now combined in the Pipelines & Terminals segment and the results from BORCO and our terminal in Yabucoa, Puerto Rico will be reported in a new International Operations business segment.

Buckeye also announced today that its general partner declared a cash distribution of $1.00 per limited partner unit for the quarter ended March 31, 2011. Class B unitholders will not receive a distribution of cash, but instead will be issued additional Class B units pursuant to Buckeye’s partnership agreement. The distribution will be payable on May 31, 2011 to unitholders of record on May 16, 2011. This cash distribution is the 28^th consecutive increase in the quarterly cash distribution and represents a 5.3 percent increase over the $0.95 per limited partner unit distribution declared for the first quarter of 2010. Buckeye has paid cash distributions in each quarter since its formation in 1986.

He has spent more than 40 years in the international terminalling business, including as Chairman of BORCO from March 2009 until February 2011. Pieter’s breadth of experience and knowledge of the industry uniquely qualify him to serve on our Board.”

EBITDA, a measure not defined under U.S. generally accepted accounting principles (“GAAP”), is defined by Buckeye as net income attributable to Buckeye’s unitholders before interest and debt expense, income taxes, and depreciation and amortization. The EBITDA measure eliminates the significant level of non-cash depreciation and amortization expense that results from the capital-intensive nature of Buckeye’s businesses and from intangible assets recognized in business combinations. In addition, EBITDA is unaffected by Buckeye’s capital structure due to the elimination of interest and debt expense and income taxes. Adjusted EBITDA, which also is a non-GAAP measure, is defined by Buckeye as EBITDA, plus: (i) non-cash deferred lease expense, which is the difference between the estimated annual land lease expense for Buckeye’s natural gas storage facility in the Natural Gas Storage segment to be recorded under GAAP and the actual cash to be paid for such annual land lease, (ii) non-cash unit-based compensation expense, and (iii) income attributable to noncontrolling interests related to Buckeye for periods prior to the merger of Buckeye and Buckeye GP

Holdings L.P. (the “Merger”); minus amortization of unfavorable storage contracts acquired in the BORCO acquisition. The EBITDA and Adjusted EBITDA data presented may not be directly comparable to similarly titled measures at other companies because EBITDA and Adjusted EBITDA exclude some items that affect net income attributable to Buckeye’s unitholders, and these measures may be defined differently by other companies. Management of Buckeye uses Adjusted EBITDA to evaluate the consolidated operating performance and the operating performance of the business segments and to allocate resources and capital to the business segments. In addition, Buckeye’s management uses Adjusted EBITDA as a performance measure to evaluate the viability of proposed projects and to determine overall rates of return on alternative investment opportunities.

Distributable cash flow, which is a financial measure included in the schedules to this press release, is another measure not defined under GAAP. Distributable cash flow is defined by Buckeye as net income attributable to Buckeye’s unitholders, plus: (i) depreciation and amortization expense, (ii) noncontrolling interests related to Buckeye that were eliminated as a result of the Merger, (iii) deferred lease expense for Buckeye’s Natural Gas Storage segment, and (iv) unit-based compensation expense (all of which are non-cash expense); minus (i) maintenance capital expenditures and (ii) amortization of unfavorable storage contracts acquired in the BORCO acquisition. Buckeye’s management believes that distributable cash flow is useful to investors because it removes non-cash items from net income and provides a clearer picture of Buckeye’s cash available for distribution to its unitholders.

EBITDA, Adjusted EBITDA, and distributable cash flow should not be considered alternatives to net income, operating income, cash flow from operations, or any other measure of financial performance presented in accordance with GAAP.

Buckeye believes that investors benefit from having access to the same financial measures used by Buckeye’s management. Further, Buckeye believes that these measures are useful to investors because they are one of the bases for comparing Buckeye’s operating performance with that of other companies with similar operations, although Buckeye’s measures may not be directly comparable to similar measures used by other companies. Please see the attached reconciliations of each of EBITDA, Adjusted EBITDA and distributable cash flow to net income attributable to Buckeye’s unitholders.
