NGL Energy Partners LP Announces Fiscal 2015 Results

TULSA, Okla.—(BUSINESS WIRE)—June 1, 2015—NGL Energy Partners LP (NYSE:NGL) today reported Adjusted EBITDA of $443.3 million for the year ended March 31, 2015 (exclusive of $7.4 million of advisory and legal costs related to acquisitions and $15.8 million of compensation costs related to the Gavilon and TransMontaigne acquisitions), compared to Adjusted EBITDA of $270.5 million during the year ended March 31, 2014 (exclusive of $6.9 million of advisory and legal costs related to acquisitions and $8.2 million of compensation costs related to the Gavilon acquisition). This represents an increase of 64% year over year. NGL reported net income of $29.9 million for the year ended March 31, 2015, compared to net income of $48.8 million for the year ended March 31, 2014.

“We are very pleased with our fiscal year 2015 results. Given the challenging energy environment, NGL significantly exceeded expectations and guidance. This is a testament to our strategy of having an integrated and diversified portfolio of midstream businesses which serve as a natural hedge against commodity risk. NGL was able to overcome backwardated markets, a 50% decline in crude oil and natural gas liquids prices and underutilized storage assets at Cushing,” said Mike Krimbill, CEO of NGL Energy Partners.

NGL’s accomplishments during fiscal 2015 also include the following:

·                  Began construction of the Grand Mesa Pipeline, a 20-inch crude oil pipeline that originates in Weld County, Colorado and terminates at NGL’s Cushing, Oklahoma terminal. NGL completed a successful open season in which it received the requisite support, in the form of ship-or-pay volume commitments from multiple shippers. Rimrock Midstream, LLC’s Platte River gathering system, which is currently under development, is expected to deliver volumes from multiple shippers to Grand Mesa’s northern origin near Lucerne, Colorado.

·                  The acquisition of TransMontaigne Inc. in July 2014. As part of the acquisition, NGL acquired the general partner interest and a 19.7% limited partner interest in TransMontaigne Partners L.P., a publicly-traded partnership that conducts refined products terminaling operations. NGL also acquired line space on Plantation and Colonial Pipelines.

·                  The acquisition of Sawtooth Caverns, the largest underground natural gas liquids storage in the Western U.S. The facility will ultimately hold 10 million barrels in 8 caverns.

·                  Expansion of NGL’s revolving credit facility that expanded the capacity to $2.296 billion.

·                  Increased the quarterly distribution from $0.55125 to $0.6250, a 13% increase, and continued our 14 consecutive quarterly increases since the IPO.

A conference call to discuss NGL’s results of operations is scheduled for 3:00pm Eastern Time (2:00pm Central Time) on Monday, June 1, 2015. Analysts, investors, and other interested parties may access the conference call by dialing (866) 318-8617 and providing access code 13096094. An archived audio replay of the conference call will be available for 7 days beginning at 7:00pm Eastern Time (6:00pm Central Time) on June 1, 2015 and can be accessed by dialing (888) 286-8010 and providing access code 94726196.

NGL defines EBITDA as net income attributable to parent equity plus interest expense, loss on early extinguishment of debt, income taxes, and depreciation and amortization expense. NGL defines Adjusted EBITDA as EBITDA excluding net unrealized gains or losses on derivatives, lower of cost or market adjustments, gains or losses on the disposal or impairment of assets, and equity-based compensation expense. EBITDA and Adjusted EBITDA should not be considered alternatives to net income, income before income taxes, cash flows from operating activities, or any other measure of financial performance calculated in accordance with accounting principles generally accepted in the United States (“GAAP”) as those items are used to measure operating performance, liquidity or the ability to service debt obligations. NGL believes that EBITDA provides additional information to investors for evaluating NGL’s ability to make quarterly distributions to NGL’s unitholders and is presented solely as a supplemental measure. NGL believes that Adjusted EBITDA provides additional information to investors for evaluating NGL’s financial performance without regard to NGL’s financing methods, capital structure and historical cost basis. Further, EBITDA and Adjusted EBITDA, as NGL defines them, may not be comparable to EBITDA and Adjusted EBITDA or similarly titled measures used by other entities.

Other than for NGL’s refined products and renewables segment, for purposes of the Adjusted EBITDA calculation, NGL makes a distinction between unrealized gains and losses on derivatives and realized gains and losses on derivatives. During the period when a derivative contract is open, NGL records changes in the fair value of the derivative as an unrealized gain or loss. When a derivative contract matures or is settled, NGL reverses the previously recorded unrealized gain or loss and records a realized gain or loss. NGL does not draw such a distinction between realized and unrealized gains and losses on the derivatives for NGL’s refined products and renewables segment. The primary hedging strategy of this segment is to hedge against the risk of declines in the value of inventory over the course of the contract cycle, and most of the hedges are six months to one year in duration at inception.

A portion of the revenues of NGL’s water solutions business is generated from the sale of crude oil that NGL recovers in the process of treating the wastewater. NGL has historically entered into derivative contracts to protect against the risk of declines in the value of the crude oil NGL expects to recover in future months. During the year ended March 31, 2015, NGL settled certain derivative contracts that related to crude oil NGL expects to recover in the months from April 2015 through September 2015 and realized a gain of $17.9 million. Of this gain, $9.4 million and $8.5 million were attributable to derivatives with scheduled settlement dates during the quarters ending June 30, 2015 and September 30, 2015, respectively.
