OREANDA-NEWS. August 09, 2016.  American Midstream Partners, LP (NYSE: AMID) (the "Partnership") today reported financial results for the three and six months ended June 30, 2016.

Highlights:

  • Second quarter 2016 Net loss attributable to the Partnership was \\$4.6 million, an increase of 120%;
  • Second quarter 2016 Adjusted EBITDA of \\$36.1 million and Distributable Cash Flow ("DCF") of \\$25.4 million, an increase of 150% and 165%, respectively;
  • Top-tier, second quarter distribution coverage of 1.94 times;
  • Contracted capacity for our Terminals segment averaged over two million barrels, an increase of 39%;
  • Maintaining focus on reducing leverage and increasing balance sheet flexibility.

EXECUTIVE COMMENTARY

"We continue to achieve strong operational and financial results, driven by our existing assets as well as our recently acquired Gulf of Mexico assets," said

Lynn Bourdon, Chairman, President and Chief Executive Officer. "We are excited about the positive impact these acquisitions have had on our business in such a short time, and we look forward to their continued performance. The Partnership continues to expand its Gulf Coast footprint, both onshore and offshore, while maintaining focus on the long-term strategy of consistent organic growth. We will also seek acquisitions that will expand our service offerings through the value chain with the objective of solidifying our position as a best-in-class integrated midstream provider."

"With the addition of the new Gulf of Mexico assets over the last nine months, the Partnership's Adjusted EBITDA increased approximately 150% over the prior-year quarter," said

Eric T. Kalamaras, Senior Vice President and Chief Financial Officer. "We seek to add incremental distributable cash flows through accretive acquisitions that drive long-term value creation. The Partnership maintained a distribution of \\$0.4125 per unit for the second consecutive quarter, and we are utilizing retained cash flows to partially fund our growth projects and increase capital flexibility."

FINANCIAL RESULTS

Net loss attributable to the Partnership for the three and six months ended June 30, 2016 was \\$4.6 million and \\$8.5 million, respectively; compared to \\$2.1 million and \\$1.2 million for the same periods in 2015, respectively. The increases to Net loss attributable to the Partnership were primarily due to higher total operating expenses and an increase in interest expense as a result of unfavorable unrealized losses on interest rate swaps and additional borrowings to fund capital growth and acquisitions, partially offset by an increase in earnings from unconsolidated affiliates.

Gross margin for the three and six months ended June 30, 2016 was \\$32.3 million and \\$59.8 million, respectively. Second quarter gross margin remained flat at \\$32.3 million over the prior-year quarter with year-to date gross margin decreasing approximately \\$6.3 million from \\$66.1 million in the prior-year period. The decrease in gross margin for the six months ended June 30, 2016 was primarily due to lower average firm and interruptible transportation throughput volumes associated with our Transmission segment, which were partially offset by higher contracted firm storage capacity in our Terminals segment over the prior-year period.

Adjusted EBITDA for the three and six months ended June 30, 2016 was \\$36.1 million and \\$56.4 million, respectively as compared to \\$14.5 million and \\$30.1 million for the same periods in 2015, respectively. Second quarter increase of \\$21.6 million and year-to-date increase of \\$26.3 million were primarily related to incremental cash flow from Delta House and recently acquired natural gas and NGL Gulf of Mexico assets.

Distributable cash flow for the three and six months ended June 30, 2016 was \\$25.4 million and \\$39.5 million, respectively an increase of 165% over the prior-year quarter, representing a distribution coverage ratio of 1.94 times. Second quarter 2016 distribution of \\$0.4125 per common unit, or \\$1.65 per unit on an annualized basis, will be paid August 12, 2016 to unitholders of record on August 3, 2016.

Reconciliations of non-GAAP financial measures of gross margin, Adjusted EBITDA, and DCF to Net income (loss) attributable to the Partnership, the most directly comparable GAAP financial measure, are provided at the end of this press release.

SEGMENT PERFORMANCE

Gathering and Processing

Second quarter gross margin was \\$20.6 million and \\$36.3 million for the three and six months ended June 30, 2016, respectively as compared to \\$20.2 million and \\$41.3 million for the same periods in 2015. The decrease in gross margin for the first six months of 2016 was primarily due to lower commodity prices and volumes, partially offset by incremental contributions from the Bakken system that commenced operations in October 2015, as well as, positive results from our newly acquired Gulf of Mexico assets.

Transmission

Second quarter gross margin was \\$7.6 million and \\$16.3 million for the three and six months ended June 30, 2016, respectively as compared to \\$9.3 million and \\$19.4 million for the same periods in 2015. The decrease in gross margin was primarily attributable to lower average firm and interruptible transportation throughput volumes.

Terminals

Second quarter gross margin was \\$4.1 million and \\$7.2 million for the three and six months ended June 30, 2016, respectively as compared to \\$2.8 million and \\$5.4 million for the same periods in 2015. The increase in gross margin was primarily attributable to increases in utilized storage capacity at the Harvey and Westwego terminal facilities, with overall terminal utilization increasing 39% over the prior-year quarter and contractual storage rate escalations.

BUSINESS HIGHLIGHTS

Gulf of Mexico Acquisition

In April 2016, the Partnership announced the acquisition of interests in Gulf of Mexico midstream assets and an incremental ownership in the Delta House floating production system and related pipeline infrastructure for total consideration of approximately \\$225.0 million. The acquired assets include non-operated interests in the Destin and Okeanos natural gas pipelines that have total capacity of 1.2 Bcf/d, and Tri-states and Wilprise NGL pipelines with total capacity of 120,000 Bbl/d. We also acquired an additional one percent non-operated indirect interest in Delta House, increasing our total investment in Delta House to approximately 13.9%.

Additionally, the Partnership acquired approximately 200 miles of crude oil, natural gas, and salt water onshore and offshore Gulf of Mexico pipelines for cash proceeds of \\$3.1 million and assumed liabilities of \\$14.3 million. These assets contributed revenue of \\$4.3 million and net income of \\$2.6 million for the period of April 15, 2016 through June 30, 2016.

CAPITAL MANAGEMENT

As of June 30, 2016, the Partnership had \\$672.4 million outstanding under its senior secured revolving credit facility and ended the quarter with leverage of 4.15 times. For the three months ended June 30, 2016, capital expenditures totaled \\$22.2 million, including \\$1.1 million for normalized maintenance capital expenditures.

RISK MANAGEMENT

The Partnership periodically enters into risk management contracts to minimize the impact of commodity prices associated with natural gas, natural gas liquids ("NGL") and crude oil. Through year-end 2016, the Partnership has hedged 43% of its expected NGL exposure and 56% of its expected crude oil exposure. Including the impact of the Partnership's risk management activities, a 10% change in oil and composite NGL prices are estimated to impact Adjusted EBITDA by less than \\$0.3 million. Further, in order to mitigate the impact of rising interest rates on floating rate debt, the Partnership has entered into \\$300.0 million in interest rate swaps, of which \\$200.0 million and \\$100.0 million is through 2019 and 2021, respectively, at an average rate of 1.3%. Details regarding the Partnership's risk management program are found in its Quarterly Report on Form 10-Q for the quarter ended June 30, 2016.

Appendix A

Note About Non-GAAP Financial Measures

Gross margin, Adjusted EBITDA, DCF, Operating margin and Segment operating margin are all non-GAAP financial measures. Each has important limitations as an analytical tool because it excludes some, but not all, items that affect the most directly comparable GAAP financial measures. Management compensates for the limitations of these non-GAAP financial measures as analytical tools by reviewing the nearest comparable GAAP financial measures, understanding the differences between the measures and incorporating these data points into management’s decision-making process.

You should not consider any of Gross margin, Adjusted EBITDA, DCF, Operating margin and Segment operating margin in isolation or as a substitute for or more meaningful than our results as reported under GAAP. Gross margin, Adjusted EBITDA, DCF, Operating margin and Segment operating margin may be defined differently by other companies in our industry. Our definitions of these non-GAAP financial measures may not be comparable to similarly titled measures of other companies, thereby diminishing their utility.

We define Adjusted EBITDA as net income (loss) attributable to the Partnership, plus interest expense, income tax expense, depreciation, amortization and accretion expense attributable to the Partnership, certain non-cash charges such as non-cash equity compensation expense, unrealized (gains) losses on commodity derivative contracts, debt issuance costs, proceeds from investments in unconsolidated subsidiaries, return of capital, transaction expenses and selected charges that are unusual or nonrecurring, less income from construction, operating and maintenance agreements ("COMA"), OPEB plans net periodic benefits, gains (losses) on sale of assets, net and selected gains that are unusual or nonrecurring. The GAAP measure most directly comparable to our performance measure Adjusted EBITDA is Net income (loss) attributable to the Partnership.

DCF is a significant performance metric used by us and by external users of the Partnership's financial statements, such as investors, commercial banks and research analysts, to compare basic cash flows generated by us to the cash distributions we expect to pay the Partnership's unitholders. Using this metric, management and external users of the Partnership's financial statements can quickly compute the coverage ratio of estimated cash flows to planned cash distributions. DCF is also an important financial measure for the Partnership's unitholders since it serves as an indicator of the Partnership's success in providing a cash return on investment. Specifically, this financial measure may indicate to investors whether we are generating cash flow at a level that can sustain or support an increase in the Partnership's quarterly distribution rates. DCF is also a quantitative standard used throughout the investment community with respect to publicly traded partnerships and limited liability companies because the value of a unit of such an entity is generally determined by the unit's yield (which in turn is based on the amount of cash distributions the entity pays to a unitholder). DCF will not reflect changes in working capital balances.

We define DCF as Adjusted EBITDA, less cash paid for interest expense, normalized maintenance capital expenditures, and distributions related to the Series A and Series C convertible preferred units. The GAAP financial measure most comparable to DCF is Net income (loss) attributable to the Partnership.

Segment gross margin and Gross margin are metrics that we use to evaluate our performance. We define Segment gross margin in our Gathering and Processing segment as total revenue generated from gathering and processing operations less unrealized gains or plus unrealized losses on commodity derivatives, less the cost of natural gas, NGLs and condensate purchased and revenue from COMA. Revenue includes revenue generated from fixed fees associated with the gathering and treatment of natural gas and from the sale of natural gas, NGLs and condensate resulting from gathering and processing activities under fixed-margin and percent-of-proceeds arrangements. The cost of natural gas, NGLs and condensate includes volumes of natural gas, NGLs and condensate remitted back to producers pursuant to percent-of-proceeds arrangements and the cost of natural gas purchased for our own account, including pursuant to fixed-margin arrangements.

We define Segment gross margin in our Transmission segment as total revenue generated from firm and interruptible transportation agreements and fixed-margin arrangements, plus other related fees, less the cost of natural gas purchased in connection with fixed-margin arrangements and revenue from COMA. Substantially all of our gross margin in this segment is fee-based or fixed-margin, with little to no direct commodity price risk.

We define Segment gross margin in our Terminals segment as revenue generated from fee-based compensation on guaranteed firm storage contracts and throughput fees charged to our customers less direct operating expense which includes direct labor, general materials and supplies and direct overhead.

We define Gross margin as the sum of our Segment gross margin for our Gathering and Processing, Transmission and Terminals segments. The GAAP measure most directly comparable to Gross margin is Net income (loss) attributable to the Partnership.

We define Segment operating margin in all of our operating segments as Segment gross margin less the direct operating expenses of that segment.

We define Operating margin as the sum of our Segment operating margin for our Gathering and Processing, Transmission and Terminals segments. The GAAP measure most directly comparable to Gross margin is Net income (loss) attributable to the Partnership.
