American Midstream Reports Record Fourth Quarter and Full Year 2014 Financial Results

American Midstream Partners LP (NYSE: AMID) ("Partnership") today reported financial results for the three and twelve months ended December 31, 2014.

Fourth quarter and full-year highlights include:

• Executed and integrated acquisitions totaling approximately $600 million to further expand the Partnership’s midstream platform in prolific U.S. resource plays, including the Eagle Ford, Permian, and Bakken;
• Expanded assets in core operating areas, including the Lavaca System in the Eagle Ford, which is currently flowing 115 million cubic feet per day ("MMcf/d"), nearly tripling since the acquisition in January 2014;
• Developed additional fee-based margin with the build-out of the Harvey Terminal, which increased the Partnership's total storage capacity by approximately 30 percent year-over-year;
• Generated record fourth quarter and full-year Adjusted EBITDA of $19.2 million and $45.6 million, respectively; and
• Increased year-over-year distributions by approximately six percent with fourth quarter and full-year distribution coverage ratios of 1.28 and 1.02, respectively.

Gross margin (a non-GAAP financial measure) for the fourth quarter of 2014 was $36.2 million, an increase of $13.3 million, or 58.1 percent, compared to $22.9 million in the prior year period. For the twelve months ended December 31, 2014, gross margin was $102.8 million compared to $74.8 million in the prior year, an increase of $28.0 million, or 37.4 percent. The increase in gross margin for the three and twelve months ended December 31, 2014 was primarily due to higher gross margin in the Partnership's Gathering and Processing segment from the January 2014 acquisition of the Lavaca System and the October 2014 acquisition of Costar Midstream, higher gross margin in the Partnership's Transmission segment as a result of the full-year benefit of the April 2013 acquisition of the High Point System, and an increase in gross margin in the Terminals segment due to the ongoing expansion of the Harvey terminal.

Adjusted EBITDA (a non-GAAP financial measure) for the three and twelve months ended December 31, 2014 was $19.2 million and $45.6 million, respectively, compared to $10.5 million and $31.9 million for same periods in 2013, increases of 82.6 percent and 42.8 percent, respectively. The fourth quarter and full year 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 ("MPOG").

Distributable cash flow ("DCF") (a non-GAAP financial measure) for the three and twelve months ended December 31, 2014 was $15.5 million and $32.7 million, respectively, representing a distribution coverage ratio of 1.28 and 1.02, respectively. The fourth quarter 2014 distribution of $12.2 million, or $0.4725 per common unit, an increase of 4.4 percent per unit over the fourth quarter 2013 distribution, was paid February 13, 2015 to unitholders of record as of February 6, 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 loss attributable to the Partnership for the three and twelve months ended December 31, 2014 was $94.3 million and $98.0 million respectively, compared to net loss of $5.6 million and $34.0 million for the fourth quarter and full year 2013. The net loss attributable to the Partnership for the three and twelve months ended December 31, 2014 included a $99.9 million asset impairment charge, partially offset by the items that increased Adjusted EBITDA described above. During the fourth quarter, the decline in commodity prices negatively impacted certain producers and shippers to whom the Partnership provides gathering and processing services. As such, impairment charges of $99.9 million were recorded on certain non-core, legacy gathering and processing assets where the Partnership anticipates limited volume growth, volume reductions as a result of the decline in commodity prices, or a decrease in gross margin attributable to the significant decrease in forecast commodity prices.

2014 BUSINESS HIGHLIGHTS

Acquisitions

The Partnership executed and integrated approximately $600 million of acquisitions during 2014 to diversify its asset base in prolific U.S. resource plays, including:

• October 2014 acquisition of Costar Midstream to expand the Partnership's operations to East Texas, the Permian, and the Bakken, funded with a combination of cash and common units issued directly to the sellers;
• August 2014 acquisition of the Main Pass Oil Gathering system to provide oil gathering services to offshore producers in the Gulf of Mexico;
• January 2014 acquisition of the Lavaca natural gas gathering system in the prolific Eagle Ford; and
• Execution of an option agreement to acquire a 50 percent interest in Republic Midstream, LLC ("Republic Midstream") at the commencement of operations, currently expected in the second half of 2015. Republic Midstream is a crude oil gathering, storage, blending, and intermediate takeaway system in the Eagle Ford being developed by an affiliate of ArcLight Capital Partners, which controls the General Partner of the Partnership.

In addition, during 2014 the Partnership received approval of a right-of-first-offer from the Board of Directors of its General Partner to acquire the Gonzales County full-well-stream gathering system ("Gonzales County") in the Eagle Ford that is being developed by the General Partner. The producer customer on the system recently announced its intention to cease drilling activities in areas served by the system. As such, the Partnership does not anticipate drop-down of the system in 2015 and will continue to evaluate timing of drop-down with the General Partner.

Organic Growth and Asset Restructuring

During 2014 the Partnership added incremental fee-based gross margin through the execution of organic growth projects and optimization of legacy assets, including:

• Significant expansion of the Lavaca System located in the prolific Eagle Ford, nearly tripling volumes to 115 MMcf/d currently since acquisition of the system in January 2014;
• Commencement of operations at the Harvey Terminal in July 2014, adding approximately 238,000 barrels in incremental storage capacity and increasing the Partnership’s total storage capacity to approximately 1.7 million barrels;
• Secured significant additional fee-based firm transportation agreements on the AlaTenn system and Magnolia gathering assets, increasing contracted volumes by approximately 50 percent on AlaTenn and more than 100 percent on Magnolia;
• Execution of an agreement in principle to retire the Midla pipeline and replace with a new 12-inch pipeline from Winnsboro, Louisiana to Natchez, Mississippi ("Natchez Line") to serve existing residential, commercial, and industrial customers. The restructuring is anticipated to result in Midla generating a reasonable return on invested capital. The agreement is subject to final agreements and ongoing proceedings at the Federal Energy Regulatory Commission; and
• Execution of a long-term, fee-based agreement in early 2015 to construct a 15-mile extension of the High Point system to serve an existing refinery customer in southeast Louisiana, which is expected to be placed into service later this year.

Capital Markets

During 2014, the Partnership executed capital markets transactions to support organic growth and acquisitions, including:

• Increased borrowing capacity on the Partnership's revolving credit facility from $200 million to $500 million with the option to further increase borrowing capacity to $700 million;
• Generated approximately $240 million of total proceeds, net of offering costs, through the issuance of common units in a public offering and private placement, as well as through the issuance of Series B Convertible Units to the Partnership's General Partner; and
• Executed an amendment related to the outstanding Series A Units whereby distributions on Series A Units will be made with paid-in-kind Series A Units, cash, or a combination thereof, which began with the distribution for the three months ended June 30, 2014 and will continue through the distribution for the three months ended March 31, 2015.

2015 ADJUSTED EBITDA, DCF, AND GROWTH CAPITAL EXPENDITURE FORECAST

The Partnership updated its 2015 forecast and now expects 2015 Adjusted EBITDA to be in a range of $85 million to $95 million and DCF in a range of $65 million to $75 million. The change to the 2015 forecast is primarily a result of significantly lower forecasted commodity prices in 2015 and the anticipated delay in the drop-down of the Gonzales County system from the Partnership's General Partner. The forecast includes the benefit of the anticipated acquisition of a 50 percent interest in Republic Midstream, 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.

2015 growth capital expenditures, which exclude capital for maintenance and acquisition capital expenditures, are anticipated to be in a range of $125 million to $135 million. Forecasted growth capital expenditures include construction of midstream infrastructure for the Lavaca and Bakken systems, completion of the Longview rail facility, construction of the Natchez Line on the Midla system, the continued build-out of the Harvey Terminal, construction of the High Point extension, and other organic growth projects.

EXECUTIVE COMMENTARY

“Our record fourth quarter and full year results reflect the successful execution of our growth strategy in 2014,” stated Steve Bergstrom, Executive Chairman, President and Chief Executive Officer. “During 2014 we significantly diversified the Partnership's asset platform with the acquisitions of the Lavaca System in January, MPOG in August, and Costar Midstream in October. We now operate assets in the majority of U.S. resource plays including the Eagle Ford, East Texas, Bakken and Permian."

"The Lavaca and Costar assets contributed significant gross margin in the gathering and processing segment, and throughputs in the transmission segment increased approximately 20 percent over 2013, primarily attributable to High Point. Our Terminals segment delivered significant year-over-year fee-based growth, expanding total storage capacity by approximately 30 percent with the successful initial build-out of the Harvey Terminal. Harvey is adding approximately 300,000 barrels of additional storage capacity in the first half of 2015 and has the potential to more than double the Partnership's existing capacity of 1.7 million barrels."

"We remain focused on executing asset development projects in 2015 that will contribute incremental, fee-based cash flow to our portfolio. We expect the Bakken crude oil gathering project to begin operations in the next few weeks and anticipate acquiring a 50 percent interest in Republic Midstream in the second half of the year. The Lavaca System located in the prolific Eagle Ford Shale is currently flowing approximately 115 MMcf/d, which is above our expectations. Construction of the Longview rail facility, which complements our existing off-spec treatment operations in East Texas, is currently underway with operations expected to commence in the second half of 2015. The facility will significantly increase the inbound supply of off-spec condensate and the outbound sales margins of marketable NGLs and blendable condensate."

"In light of the dynamic commodity price environment, we updated our 2015 forecast and currently expect Adjusted EBITDA of approximately $90 million at the midpoint of our guidance range, approximately double our 2014 Adjusted EBITDA, and the expectation to hold our current distribution flat in 2015 in order to maintain distribution coverage at approximately one times. In addition, we lowered our growth capital expenditure forecast to reflect updated timing of capital expenditures and ongoing efforts to operate prudently in the current price environment."

"In 2014 we delivered on our strategy by diversifying the Partnership in major U.S. resource plays and executing significant asset development projects. Looking ahead, we are actively engaged in expanding our asset base through organic expansion projects as well as third-party and drop-down acquisitions. We remain committed to delivering long-term, sustainable distribution growth to our unitholders, and ArcLight Capital, which controls our General Partner, remains strongly supportive of our long-term growth strategy."

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 NGLs to various markets and pipeline systems.

Segment gross margin for the Gathering and Processing segment was $19.7 million and $50.8 million for the three and twelve months ended December 31, 2014, respectively, compared to $8.2 million and $37.0 million for the three and twelve months ended December 31, 2013. The increase in gross margin for the fourth quarter and full-year was primarily attributable to the incremental gross margin from the Lavaca System as well as the Longview, Chapel Hill, and Yellow Rose assets acquired with the Costar Midstream acquisition, partially offset by lower throughput volumes on the Partnership's legacy assets.

Natural gas throughput volumes averaged 320.3 MMcf/d and 274.8 MMcf/d for the three and twelve months ended December 31, 2014, respectively, compared to 298.2 MMcf/d and 277.2 MMcf/d for the fourth quarter and full year 2013. Processed NGLs averaged 138.4 thousand gallons per day ("Mgal/d") and 64.2 Mgal/d for the three and twelve months ended December 31, 2014, respectively, compared to 49.6 Mgal/d and 52.0 Mgal/d for the same periods in 2013. The increase in natural gas throughput volumes for the fourth quarter was primarily attributable to the addition of the Lavaca System as well as the Costar Midstream assets, partially offset by lower throughputs from the Partnership's legacy assets. The decrease in natural gas throughput for the full year 2014 was primarily attributable to lower throughputs from the Partnership's legacy assets, partially offset by increased throughput from the Lavaca System and the Costar Midstream assets. The increase in processed NGLs for the three and twelve months ended December 31, 2014, was attributable to the addition of the Costar Midstream assets in the fourth quarter, partially offset by lower processed NGLs from the Partnership's legacy assets.

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 $13.8 million and $42.8 million for the three and twelve months ended December 31, 2014, respectively, compared to $13.1 million and $32.4 million for the three and twelve months ended December 31, 2013. The increase in gross margin for the fourth quarter and full year was attributable to the full-year benefit of the April 2013 acquisition of the High Point System.

Total natural gas throughput volumes averaged 803.4 MMcf/d and 778.9 MMcf/d for the three and twelve months ended December 31, 2014, respectively, compared to 743.8 MMcf/d and 644.7 MMcf/d for the three and twelve months ended December 31, 2013. The increase in throughput volume for the three and twelve months ended December 31, 2014 was primarily due to the additional volumes on the High Point System.

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 and $9.2 million for the three and twelve months ended December 31, 2014, respectively, compared to $1.6 million and $5.4 million for the three and twelve months ended December 31, 2013. The increase in gross margin was attributable to an approximate 30 percent increase in storage capacity in 2014 compared to 2013 as a result of incremental capacity constructed in 2014, as well as full-year results in 2014 compared to less than nine months in 2013 as the Partnership did not have a Terminals segment for the three months ended March 31, 2013.

BALANCE SHEET

As of December 31, 2014, the Partnership had $0.5 million of cash on hand, and $374.6 million outstanding under its senior secured revolving credit facility. For the three and twelve months ended December 31, 2014, capital expenditures totaled $55.8 million and $97.0 million, respectively, which included $2.1 million and $6.2 million for maintenance capital, respectively. 2014 capital expenditures were primarily attributable to expansion of the Lavaca System, construction of the Bakken and Longview systems, completion of the Yellow Rose plant, 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 December 31, 2014, approximately four percent of the Partnership's exposure to NGL prices is hedged through the first half of 2015. Details regarding the Partnership's hedge program are found in its Annual Report on Form 10-K for the quarter ended December 31, 2014.

CONFERENCE CALL INFORMATION

The Partnership will host a conference call at 10:00 a.m. Eastern Time on Tuesday, March 10, 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.
