Enbridge Energy Partners, L.P. Reports 2014 Earnings and Announces 2015 Financial Guidance

HOUSTON — (February 18, 2015) - Enbridge Energy Partners, L.P. (NYSE:EEP) (“Enbridge Partners” or “the Partnership”) reports adjusted EBITDA for the three months ended December 31, 2014 and full year 2014 of $443.3 million and $1.55 billion, respectively.

2014 HIGHLIGHTS

“In 2014, the Partnership’s strong financial performance was supported by record deliveries on our Lakehead and North Dakota liquids pipeline systems, in addition to the meaningful cash flow contributions from the execution of our multi-billion dollar organic growth program. We expect deliveries on our liquids pipeline systems to remain strong in 2015 as we continue to progress our market access programs, providing our customers with expanded pipeline takeaway capacity from Western Canada and the Bakken formation to premium North American crude oil markets. With the backdrop of volatile commodity prices, the Partnership’s competitive transportation rates and resulting cash flows are predominantly underpinned by long term low-risk commercial structures, such as cost of service and take-or-pay, which largely mitigate the sensitivity to volume and commodity prices to our business’s distributable cash flow,” said Mark Maki, president for the Partnership.

“Looking forward, our organic growth program is proceeding well and we expect to place several projects into service during 2015 that will increase our cash flows. The Partnership recently closed on the previously announced $1 billion drop down acquisition of the remaining 66.7 percent interest in the U.S. segment of the Alberta Clipper Pipeline from Enbridge. With full year contribution from the Eastern Access projects placed into service during 2014 and organic growth projects targeted to enter service this year, the Partnership anticipates earnings and distributable cash flow growth in 2015. This growth in distributable cash flow positions the Partnership to deliver annual distribution growth of 2 to 5 percent for 2015.”

“We are excited about the long term outlook for the Partnership. A key development in the fourth quarter was the announcement by Enbridge that it is reviewing a potential restructuring plan that would involve the transfer of its directly held U.S. liquids pipeline assets to the Partnership. While we expect this review to be concluded by mid-year, the potential drop down of Enbridge’s U.S. liquids pipelines systems would add substantial new sources of long-lived and growing cash flows to the Partnership’s already exceptional portfolio of liquids pipeline systems. The restructuring plan under consideration by Enbridge once again demonstrates the strategic alignment and support of our sponsor Enbridge, and its commitment to enhancing the value of the Partnership for all of our investors,” noted Maki.

The Partnership expects adjusted EBITDA for 2015 to increase approximately 12 percent, to between $1.68 billion and $1.78 billion, and expects distributable cash flow for 2015 to increase approximately 15 percent, to be between $900 million to $960 million.

The Partnership’s key financial results for the three and twelve months ended December 31, 2014, compared to the same periods in 2013, were as follows:

Adjusted net income for the three and twelve month periods ended December 31, 2014, as reported above, eliminates the effect of: (a) additional environmental costs, net of insurance recoveries, associated with the Line 6B incident; (b) non-cash, mark-to-market net gains and losses and other adjustments. Refer to the Non-GAAP Reconciliations section below for additional details.

Adjusted net income of $132.5 million for the fourth quarter of 2014 was $59.4 million higher than the same period from the prior year. Higher earnings were primarily attributable to higher transportation rates, higher deliveries and contributions from pipeline expansion projects entering service in our liquids pipeline segment.

During the fourth quarter, the Partnership attributed approximately $22.5 million of earnings to its outstanding Series 1 Preferred units. This amount is deducted from net income to arrive at the amount of net income attributable to the general and limited partners. Preferred distributions are accrued at an annual rate of 7.5 percent through June 30, 2015. The Partnership may defer payment of those accrued amounts until the earlier of May 8, 2018 or the date on which the Partnership redeems the preferred units.

COMPARISON OF QUARTERLY RESULTS

Following are explanations for significant changes in the Partnership’s financial results, comparing the three and twelve month periods ended December 31, 2014 with the same periods of 2013. The comparison refers to adjusted operating income, which excludes the effect of non-cash and nonrecurring items (see Non-GAAP Reconciliations section below).

Liquids – Fourth quarter adjusted operating income for the Liquids segment increased $120.6 million to $306.4 million from $185.8 million for the comparable period in 2013. Higher revenues in the fourth quarter were attributable to an increase in transportation rates and higher deliveries on all our liquids pipeline systems. Total liquids system deliveries increased approximately 20 percent over the same period from the prior year due to crude oil supply growth in western Canada and the Bakken Formation, along with Enbridge and the Partnership’s pipeline expansion projects entering service. The Partnership completed a large component of its Eastern Access Program, specifically the Line 6B Replacement project from Griffith, Indiana to the International Border, in two phases in 2014. The 160-mile segment of the Line 6B Replacement project from Griffith, Indiana to Stockbridge, Michigan entered service May 1, 2014, and the remaining 50-mile segment of the Line 6B Replacement to the International Border, which entered service September 30, 2014. Additionally, the first phase of the Line 61 Mainline Expansion began service August 1, 2014. Collectively, these growth projects contributed to the increase in revenues during the fourth quarter over the comparable period in 2013.

Natural Gas – Fourth quarter adjusted operating income for the Natural Gas segment was $0.7 million higher compared to the same period of 2013. The increase in adjusted operating income was attributable to higher storage margins resulting from the sale of liquids product inventory in our marketing business and lower operating and administrative expenses, partially offset by decreased gross margin due to lower NGL prices and lower natural gas throughput on our major systems.

NON-GAAP RECONCILIATIONS

Adjusted net income and adjusted operating income for the principal business segments are provided to illustrate trends in income excluding derivative fair value losses and gains and other nonrecurring items that affect earnings. The derivative non-cash losses and gains result from marking to market certain financial derivatives used by the Partnership for hedging purposes that do not qualify for hedge accounting treatment in accordance with the authoritative accounting guidance as prescribed under generally accepted accounting principles in the United States.

Adjusted EBITDA (earnings before interest, taxes, depreciation and amortization) is used as a supplemental financial measurement to assess liquidity and the ability to generate cash sufficient to pay interest costs and make cash distributions to unitholders. The following reconciliation of net cash provided by operating activities to adjusted EBITDA is provided because EBITDA is not a financial measure recognized under generally accepted accounting principles.
