BUCKEYE PARTNERS, L.P. REPORTS 2012 SECOND QUARTER EARNINGS RESULTS

AND DECLARES CASH DISTRIBUTION

HOUSTON, August 3, 2012 — Buckeye Partners, L.P. (“Buckeye”) (NYSE: BPL) today reported net income attributable to Buckeye’s unitholders for the second quarter of 2012 of $54.4 million, or $0.55 per diluted unit, compared to net income attributable to Buckeye’s unitholders for the second quarter of 2011 of $92.0 million, or $1.00 per diluted unit. Buckeye’s Adjusted EBITDA (as defined below) for the second quarter of 2012 was $119.9 million compared with Adjusted EBITDA of $117.6 million for the second quarter of 2011. Operating income for the second quarter of 2012 was $81.8 million compared to $85.9 million for the second quarter of 2011. Net income attributable to Buckeye’s unitholders for the second quarter of 2011 benefited from a gain of $34.1 million on the sale of a minority equity interest in West Texas LPG Pipeline Limited Partnership.

“Improvement in our Adjusted EBITDA over the second quarter of 2011 primarily reflects the successful integration of our pipeline and terminal acquisitions made during 2011,” stated Clark C. Smith, President and Chief Executive Officer. “During the quarter, we experienced improving business conditions for our domestic pipelines and terminals as well as in our international operations, though we continue to be challenged in our Energy Services segment as backwardation and continued basis volatility negatively impacted our results. Looking forward, strengthening domestic volumes and increasing demand for storage, both domestically and internationally, are expected to contribute to improved results.”

Mr. Smith continued, “We are excited to be moving forward with our integration and commercialization plans on our recently completed purchase of the Perth Amboy, New Jersey, marine terminal facility. Our teams are working to transform this facility into a highly-efficient, multi-product storage, blending, and throughput facility with a direct connection to our Linden complex. Another important milestone reached during the second quarter was the execution of a lease agreement with a major international petroleum company for 1.1 million barrels of storage capacity that was placed into service July 1, representing the initial phase of our BORCO expansion.”

Buckeye also announced today that its general partner declared a cash distribution of $1.0375 per limited partner (“LP”) unit for the quarter ended June 30, 2012. 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 August 31, 2012 to unitholders of record on August 15, 2012. This cash distribution represents a 2.5% increase over the $1.0125 per LP unit distribution declared for the second quarter of 2011. Buckeye has paid cash distributions in each quarter since its formation in 1986.

Adjusted EBITDA and distributable cash flow are measures not defined by GAAP. Adjusted EBITDA is the primary measure used by our senior management, including our Chief Executive Officer, to (i) evaluate our consolidated operating performance and the operating performance of our business segments, (ii) allocate resources and capital to business segments, (iii) evaluate the viability of proposed projects, and (iv) determine overall rates of return on alternative investment opportunities. Distributable cash flow is another measure used by our senior management to provide a clearer picture of Buckeye’s cash available for distribution to its unitholders. Adjusted EBITDA and distributable cash flow eliminate (i) non-cash expenses, including, but not limited to, depreciation and amortization expense resulting from the significant capital investments we make in our businesses and from intangible assets recognized in business combinations, (ii) charges for obligations expected to be settled with the issuance of equity instruments, and (iii) items that are not indicative of our core operating performance results and business outlook.

Buckeye believes that investors benefit from having access to the same financial measures used by senior management and that these measures are useful to investors because they aid in comparing Buckeye’s operating performance with that of other companies with similar operations. The Adjusted EBITDA and distributable cash flow data presented by Buckeye may not be comparable to similarly titled measures at other companies because these items may be defined differently by other companies. Please see the attached reconciliations of each of Adjusted EBITDA and distributable cash flow to net income.
