American Midstream Reports First Quarter 2015 Financial Results

American Midstream Partners, LP (NYSE: AMID) ("Partnership") today reported financial results for the three months ended March 31, 2015. Gross margin (a non-GAAP financial measure) for the first quarter 2015 was $33.8 million, an increase of $10.7 million, or 46.3 percent, from $23.1 million in the prior year period. The increase in gross margin for the three months ended March 31, 2015 was primarily due to higher gross margin in the Partnership's Gathering and Processing segment from the October 2014 acquisition of Costar Midstream and the January 2014 acquisition of the Lavaca System, which has tripled throughput volume since the acquisition.

Adjusted EBITDA (a non-GAAP financial measure) for the three months ended March 31, 2015 was $15.6 million, in-line with the Partnership's guidance for full-year 2015. Adjusted EBITDA for the three months ended March 31, 2015 increased $5.0 million, or 47.2 percent, compared to $10.6 million for same period in 2014. The first quarter 2015 increase in Adjusted EBITDA was primarily related to the above-mentioned acquisitions as well as the benefit of the August 2014 acquisition of the Main Pass Oil Gathering System.

Distributable cash flow ("DCF") (a non-GAAP financial measure) for the three months ended March 31, 2015 was $11.7 million, representing a distribution coverage ratio of 0.96, and in-line with the Partnership's guidance to maintain distribution coverage at approximately 1.00 in 2015. The first quarter 2015 distribution of $12.2 million, or $0.4725 per common unit, an increase of 2.2 percent per unit from the first quarter 2014 distribution, will be paid on May 15, 2015 to unitholders of record as of May 7, 2015.

Reconciliations of the non-GAAP financial measures 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.

Net income attributable to the Partnership for the three months ended March 31, 2015 was $0.8 million, compared to net income of $0.4 million for the first quarter 2014. The increase in net income attributable to the Partnership for the three months ended March 31, 2015 was primarily attributable to the reasons for the increase in gross margin discussed above, partially offset by an incremental increase in direct operating expenses associated with the Costar Midstream and Lavaca System acquisitions.

BUSINESS HIGHLIGHTS

Harvey Terminal

Terminal storage capacity at Harvey increased to 387,800 barrels as of mid-April 2015 with the addition of 150,000 barrels of incremental capacity, of which 100 percent is leased under multi-year, firm storage contracts. Construction of an additional 150,000 barrels and the deep-water ship dock are currently underway with expected completion in the second quarter. The terminal has the potential for more than two million barrels of capacity when fully developed, which would increase the Partnership's total storage capacity by more than 100 percent.

Midla Restructuring

On April 16, 2015, the Federal Energy Regulatory Commission issued an order accepting the Stipulation and Agreement ("Midla Settlement") filed by American Midstream (Midla), LLC ("Midla") on December 11, 2014. The Midla Settlement allows Midla to retire the existing 1920s vintage pipeline and replace it with a new, 12-inch pipeline from Winnsboro, Louisiana to Natchez, Mississippi (the “Midla-Natchez pipeline”) to serve existing residential, commercial, and industrial customers under long-term agreements ranging from 10 to 15 years, plus renewal options. The Partnership expects to place the Midla-Natchez pipeline into service in late 2016.

Series A-2 Convertible Preferred Units

On March 30, 2015, the Partnership entered into a Series A-2 Convertible Preferred Unit Purchase Agreement with an affiliate of its General Partner pursuant to which the Partnership issued 1,142,858 Series A-2 Units for approximately $20 million in aggregate proceeds. Distributions related to the newly issued Series A-2 Convertible Preferred Units and existing Series A Convertible Preferred Units will be made with paid-in-kind Series A Preferred Units, cash, or a combination thereof, at the discretion of the Board of Directors of the Partnership's General Partner through the first quarter 2016 distribution, payable in May 2016, or the time at which the Units are converted into common units.

High Point Lateral

In February 2015, the Partnership executed a 15-year, fee-based agreement to construct a 15-mile extension of the High Point system to serve an existing refinery customer in southeast Louisiana. Construction of the lateral will commence during the second quarter and is expected to be placed into service later this year.

2015 ADJUSTED EBITDA, DCF, AND GROWTH CAPITAL EXPENDITURE FORECAST

The Partnership's forecast for 2015 Adjusted EBITDA and DCF remains unchanged in a range of $85 million to $95 million and $65 million to $75 million, respectively. The forecast includes the benefit of the anticipated acquisition of a 50 percent interest in Republic Midstream in the second half of 2015, and does not include the benefit of additional acquisitions, drop downs, or asset development projects the Partnership may pursue. The 2015 forecast also reflects current expectations of operational volumes and derivative instruments outstanding.

Growth capital expenditures for 2015, which exclude capital expenditures for maintenance and acquisitions, are also unchanged in a range of $125 million to $135 million. Forecasted growth capital expenditures include construction of additional midstream infrastructure for the Lavaca system, construction of the Longview rail facility, construction of the Bakken crude oil gathering system, construction of the Midla-Natchez pipeline, the continued build-out of the Harvey Terminal, construction of the High Point lateral, and other organic growth projects.

EXECUTIVE COMMENTARY

“We are off to a strong start in 2015, with first quarter results in-line with our expectations and we remain on-track to achieve our 2015 guidance," said Steve Bergstrom, Executive Chairman, President and Chief Executive Officer. "The ongoing diversification of our midstream platform into key U.S. resource plays mitigates the challenging price environment and, despite year-over-year reductions in commodity prices of approximately 50 percent, we delivered strong adjusted EBITDA growth of nearly 50 percent.

"A key focus in 2015 is execution of asset-development projects that will contribute incremental, fee-based cash flow to our portfolio, including ongoing expansion of the Lavaca System where volumes have tripled since the January 2014 acquisition, commissioning the Bakken crude oil gathering system in the second quarter, completion in the third quarter of the Longview rail facility to complement our East Texas off-spec treating operations, and construction of the Permian off-spec treating joint venture with EnLink Midstream expected to be online in late 2015. In addition, we are constructing the High Point lateral to serve an existing refinery customer in late 2015, further expanding the Harvey terminal, which is well ahead of expectations, and commencing construction on the Midla-Natchez pipeline with operations expected in late 2016. Further, in the second half of 2015 we anticipate exercising our option to acquire a 50 percent interest in the Republic Midstream crude oil system in the Eagle Ford under development by an affiliate of ArcLight Capital, which controls our General Partner.

"Looking ahead, we reiterated our 2015 guidance, with Adjusted EBITDA expected to approximately double compared to our 2014 Adjusted EBITDA, and the continued expectation to hold our distribution flat during 2015 to maintain distribution coverage at approximately one times. ArcLight continues to be strongly supportive of American Midstream, and we are actively engaged in expanding our asset base through organic expansion projects as well as third-party and drop-down acquisitions, while remaining committed to delivering long-term, sustainable distribution growth to our unitholders."

SEGMENT PERFORMANCE

Gathering and Processing - The Gathering and Processing segment includes natural gas transportation, gathering, treating, processing, fractionation, and marketing or re-delivery of natural gas and natural gas liquids ("NGLs") to various markets and pipeline systems.

Segment gross margin for the Gathering and Processing segment was $21.0 million for the three months ended March 31, 2015 compared to $10.1 million for the three months ended March 31, 2014. The increase in gross margin for the first quarter 2015 was primarily attributable to incremental gross margin from assets acquired with the Costar Midstream acquisition, as well as incremental gross margin from the Lavaca System, partially offset by decreases in commodity prices of approximately 50 percent compared to the prior-year quarter.

Natural gas throughput volumes averaged 372.1 million cubic feet per day ("MMcf/d") for the three months ended March 31, 2015 compared to 284.1 MMcf/d for the three months ended March 31, 2014. Processed NGLs averaged 269.1 thousand gallons per day ("Mgal/d") for the three months ended March 31, 2015 compared to 38.6 Mgal/d for the same period in 2014. The increase in natural gas throughput volumes for the first quarter was primarily attributable to the addition of the Costar Midstream assets as well as the Lavaca System, partially offset by lower throughput volumes from the Partnership's legacy assets. The increase in processed NGLs for the three months ended March 31, 2015 was primarily attributable to the addition of the Longview operations as part of the Costar Midstream acquisition.

Transmission - The Transmission segment transports and delivers natural gas from producing wells, receipt points, or pipeline interconnects to pipeline or end-use markets primarily under fee-based and firm transportation agreements.

Segment gross margin for the Transmission segment was $10.1 million for the three months ended March 31, 2015 compared to $11.0 million for the three months ended March 31, 2014. The decrease in gross margin for the first quarter was attributable to lower average throughput volumes compared to the prior-year quarter.

Total natural gas throughput volumes averaged 811.0 MMcf/d for the three months ended March 31, 2015 compared to 864.2 MMcf/d for the three months ended March 31, 2014. The decrease in throughput volume for the three months ended March 31, 2015 was primarily due to decreased volumes on the High Point system as a result of producer and pipeline maintenance activities in the first half of the year.

Terminals - The Terminals segment provides above-ground, fee-based storage services at the Partnership's marine terminals to support various commercial customers, including commodity brokers, refiners and chemical manufacturers to store a range of products, including chemicals, distillates, and agricultural products.

Segment gross margin for the Terminals segment was $2.7 million for the three months ended March 31, 2015 compared to $1.9 million for the three months ended March 31, 2014. The increase in gross margin was primarily attributable to increases in contracted storage capacity at the Harvey and Westwego terminals and associated ancillary services.

BALANCE SHEET

As of March 31, 2015, the Partnership had $392.0 million outstanding under its senior secured revolving credit facility. For the three months ended March 31, 2015, capital expenditures totaled $38.9 million, which included $1.1 million for maintenance capital. First quarter 2015 capital expenditures were primarily attributable to expansion of the Lavaca System, construction of the Bakken system and Longview rail facility, and the ongoing build-out of the Harvey Terminal.

DERIVATIVES

The Partnership enters into derivative agreements to hedge exposure to commodity prices associated with natural gas, NGLs, and crude oil. As of March 31, 2015, approximately 14 percent of the Partnership's exposure to NGL prices was hedged through the end of 2015. Subsequent to the end of the first quarter, the Partnership entered into additional derivative contracts and approximately 36 percent of the Partnership’s exposure to NGL prices in 2015 is hedged currently, excluding ethane. Details regarding the Partnership's hedge program are found in its Quarterly Report on Form 10-Q for the quarter ended March 31, 2015.

CONFERENCE CALL INFORMATION

The Partnership will host a conference call at 10:00 a.m. Eastern Time on Tuesday, May 12, 2015 to discuss results. The call will be webcast and archived on the Partnership’s website for a limited time.

Appendix A

Note About Non-GAAP Financial Measures

Gross margin, adjusted EBITDA and distributable cash flow 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 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 or distributable cash flow in isolation or as a substitute for or more meaningful than our results as reported under GAAP. Gross margin, adjusted EBITDA and distributable cash flow 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, plus interest expense, income tax expense, depreciation expense, certain non-cash charges such as non-cash equity compensation, unrealized losses on commodity derivative contracts, cash distributions in excess of earnings from unconsolidated affiliates and selected charges that are unusual or nonrecurring, less interest income, income tax benefit, unrealized gains on commodity derivative contracts, amortization of commodity put purchase costs, and selected gains that are unusual or nonrecurring. The GAAP measure most directly comparable to adjusted EBITDA is net income (loss) attributable to the Partnership.

Distributable cash flow 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. Distributable cash flow 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. Distributable cash flow 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). Distributable cash flow will not reflect changes in working capital balances.

We define distributable cash flow as adjusted EBITDA plus interest income, less cash paid for interest expense, normalized maintenance capital expenditures, and dividends related to the Series A convertible preferred units. The GAAP financial measure most comparable to distributable cash flow is net income (loss) attributable to the Partnership.

The GAAP measure most directly comparable to forecasted adjusted EBITDA and distributable cash flow is net income (loss) attributable to the Partnership. Net income attributable to the Partnership is forecasted to be approximately $35 million to $45 million in 2015.

Gross margin and segment gross margin are metrics that we use to evaluate our performance. We define segment gross margin in our Gathering and Processing segment as revenue generated from gathering and processing operations less the cost of natural gas, NGLs and condensate purchased and revenue from construction, operating and maintenance agreements ("COMA"). Revenue includes revenue generated from fixed fees associated with the gathering and treating 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 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. 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 comparable to gross margin is net income (loss) attributable to the Partnership.
