Exterran Corporation
Annual Report 2017

Plain-text annual report

To our Stockholders, Exterran had an outstanding year in 2017, delivering solid financial performance, growth in new orders and backlog, improved liquidity and enhanced operational efficiencies during a period when many companies were still recovering from the multi-year decline in energy prices. In addition, we delivered on the following internal initiatives that sets the foundation for our future:  Enhanced our existing strong focus on safety, resulting in best in class safety metrics;  Evolved our key internal processes, controls, and procedures to fortify our systems, controls and management systems to better serve our stakeholders;  Introduced a culture to improve how we do business with customers and collaborate with each other;  Refreshed our Core Values and Code of Business Conduct which included reaching out to every employee and contractor around the world to set clear expectations; and  Globally, we welcomed new outstanding talent to an already world-class team. These accomplishments represent the results of the hard work, perseverance and adaptability of our approximately 4,500 global associates. Focus in the face of adversity also describes our year as our employees came together as One Exterran in the wake of an epic natural disaster to help others. The devastation from Hurricane Harvey was unimaginable, but the goodness and strength of the human spirit displayed by Exterran employees around the world and the way they rallied to support co-workers and our communities was nothing short of inspirational. While many of the memories from Harvey are of suffering and loss, the more powerful recollections will be about hope and kindness. That focus was also evident in our ability to deliver solid financial results. Our 2017 revenue was $1.2 billion, a 34% increase from 2016, while our gross margin grew to $347 million, up 12% from the prior year. We grew our contract operations segment gross margin percentage to 64.5% in 2017, up from 63.4% in 2016. In addition, while our existing project renewal rate was high in 2017 we were able to increase project productivity by re-scoping projects, allowing us to maintain and in some cases increase our margins. The largest revenue growth came from our product sales segment, as North America demand for midstream infrastructure resulted in strong increases in revenue, margins and overall profitability. Revenue in our product sales segment increased 87% to $733 million. In addition, we booked close to $890 million in product orders during the year, including orders for almost three billion standard cubic feet per day of processing and treating gas plant capacity. The strong order flow ensures a solid product backlog of $461 million at year end 2017 from which we will drive product sales revenue and profits in 2018 at higher margins than we delivered in 2017. We achieved a double-digit gross margin percentage in our product sales segment of 10.4%. Our gross margin percentage achieved in the fourth quarter of 2017 was 11.6%, up from 3.2% in the fourth quarter of 2016, reflecting the improved volumes and impact of productivity. Our financial performance combined with our ongoing focus on cash and working capital management allowed us to fund our operations and capital expenditures primarily through internally generated cash flows. Working capital as a percentage of revenue improved to 10.5% in 2017 from 26.7% in 2016, a remarkable accomplishment in a period of growth and investment. This resulted, as of December 31, in our cash balance of $49.1 million, with long-term debt of $368.5 million. As a result, our leverage ratio (debt to adjusted EBITDA as defined in our credit agreement) was 1.7 times as compared with 2.3 at December 31, 2016. As we move into a new era for Exterran, our focus pivots to strategy, growth and returns. We are evolving into a systems and process company focused on oil, gas, water and power. We intend to win through differentiated products with services pull through. We will infuse technology and innovation into our existing midstream product families while developing new offerings in water and integrated power generation. Our go-to-market strategy will be executed by our regional operating model and supported by our global engines and centers of excellence. We expect to see strong markets for our products and services, although likely we will see differences regionally. Drivers of incremental growth in the North America natural gas market will continue to be liquefied natural gas exports, petrochemical growth and exports to Mexico. Takeaway capacity is increasing in the northeast U.S. and west Texas, making more product available to multiple regions. Service will become an increasingly important part of the midstream infrastructure market, as cost, efficiency and emissions will demand technical innovation. We do anticipate possible volatility in orders as customers digest the capacity ordered in 2017. Latin America remains our largest international region. Increasing natural gas production is expected from the Vaca Muerta shale play in Argentina, which should allow us to grow our presence and expand our customer base. Reforms and growth in Brazil and Mexico could drive renewed demand for gas processing and treating plants. In the Middle East and Africa, we see a strong pipeline of opportunities to offer customers our full complement of midstream solutions, both on a service and equipment sales basis. The inquiry-to-order cycle time can be lengthy and lumpy, but we have a line of sight into opportunities to help customers monetize their hydrocarbons quicker than they could with larger plants which take years to build and install. The Asia Pacific region is in need of midstream technical expertise, which should drive penetration of our aftermarket service business. We see opportunities to develop and leverage strategic relationships in several areas in the region. Local capability is often required, and we believe our manufacturing facility in Singapore also provides us a competitive advantage. In summary, 2017 was an exciting year for Exterran, capped by a 31.5% increase in our stock price which followed a 48.9% increase in 2016. The foundation is now set for us to execute and deliver on our vision to continue to increase shareholder returns. We want to thank our employees for their contributions in 2017 and recognize all of our stakeholders, including customers, lenders and shareholders, for their ongoing support and interest in Exterran.

Item 1. Business Exterran Corporation (together with its subsidiaries, “Exterran Corporation,” “our,” “we” or “us”), a Delaware corporation formed in March 2015, is a global systems and process company offering solutions in the oil, gas, water and power markets. We are a market leader in natural gas processing and treatment and compression products and services, providing critical midstream infrastructure solutions to customers throughout the world. Outside the United States of America (“U.S.”), we are a leading provider of full-service natural gas contract compression, and a supplier of aftermarket parts and services. Our manufacturing facilities are located in the U.S., Singapore and the United Arab Emirates. Spin-off On November 3, 2015, Archrock, Inc. (named Exterran Holdings, Inc. prior to November 3, 2015) (“Archrock”) completed the spin-off (the “Spin-off”) of its international contract operations, international aftermarket services (the international contract operations and international aftermarket services businesses combined are referred to as the “international services businesses” and include such activities conducted outside of the U.S.) and global fabrication businesses into an independent, publicly traded company named Exterran Corporation. We refer to the global fabrication business previously operated by Archrock as our product sales business. To effect the Spin-off, on November 3, 2015, Archrock distributed, on a pro rata basis, all of our shares of common stock to its stockholders of record as of October 27, 2015 (the “Record Date”). Archrock shareholders received one share of Exterran Corporation common stock for every two shares of Archrock common stock held at the close of business on the Record Date. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, we transferred cash of $532.6 million to Archrock. Our Registration Statement on Form 10, as amended, was declared effective on October 21, 2015. On November 4, 2015, Exterran Corporation common stock began “regular-way” trading on the New York Stock Exchange under the stock symbol “EXTN.” Following the completion of the Spin-off, we and Archrock became and continue to be independent, publicly traded companies with separate boards of directors and management. General We provide our products and services to a global customer base consisting of companies engaged in all aspects of the oil and natural gas industry, including large integrated oil and natural gas companies, national oil and natural gas companies, independent oil and natural gas producers and oil and natural gas processors, gatherers and pipeline operators. We operate in three primary business lines: contract operations, aftermarket services and product sales. The nature and inherent interactions between and among our business lines provide us with opportunities to cross-sell or offer integrated product and service solutions to our customers. For financial data relating to our reportable business segments or countries that accounted for 10% or more of our revenue in any of the last three fiscal years or 10% or more of our property, plant and equipment, net, as of December 31, 2017, 2016 or 2015, see Part II, Item 7 (“Management’s Discussion and Analysis of Financial Condition and Results of Operations”) and Note 23 to our Consolidated and Combined Financial Statements included in Part IV, Item 15 (collectively referred to as “Financial Statements,” and individually referred to as “balance sheets,” “statements of operations,” “statements of comprehensive income (loss),” “statements of stockholders’ equity” and “statements of cash flows” herein). We are currently in the process of transitioning into four regional structures to more effectively and efficiently serve our customer needs. We do not anticipate that this will fundamentally change how we deploy capital. Contract Operations In our contract operations business, we own and operate natural gas compression equipment and crude oil and natural gas production and processing equipment on behalf of our customers outside of the U.S. We provide comprehensive contract operations services to our customers based on each customer’s needs and operating specifications. Our services include the provision of personnel, equipment, tools, materials and supplies to meet our customers’ natural gas compression or oil and natural gas production and processing service needs. Activities we may perform in meeting our customer’s needs include engineering, designing, sourcing, constructing, installing, operating, servicing, repairing, maintaining and decommissioning equipment owned by us necessary to provide these services. We generally enter into contracts with our contract operations customers with initial terms ranging between three to five years, and in some cases, in excess of 10 years. In many instances, we are able to renew those contracts prior to the expiration of the initial term and in other instances, we may sell the underlying assets to our customers pursuant to purchase options or negotiated sale. If a contract is not renewed or a customer does not purchase the underlying assets, our equipment is returned to our premises for future redeployment. These contracts may require us to make significant investments in equipment, facilities and related installation costs. These projects may include several compressor units on one site or entire facilities designed to process and treat oil or natural gas to make it suitable for end use. Our commercial contracts generally require customers to pay a monthly service fee even during periods of limited or disrupted oil or natural gas flows, which we believe provide us with relatively stable and predictable cash flows. Additionally, because we typically do not take title to the oil or natural gas we compress, process or treat, and because the natural gas we use as fuel for our equipment is supplied by our customers, we have limited direct exposure to short-term commodity price fluctuations. Our equipment is maintained in accordance with established maintenance schedules. These maintenance procedures are updated as technology changes and as our operations team develops new techniques and procedures. In addition, because our field technicians provide maintenance on our contract operations equipment, they are familiar with the condition of our equipment and can readily identify potential problems. In our experience, these maintenance procedures maximize equipment life and unit availability, minimize avoidable downtime and lower the overall maintenance expenditures over the equipment life. We believe our contract operations services generally allow our customers to achieve higher production rates than they would achieve with their own operations, resulting in increased revenue for our customers. In addition, outsourcing these services allows our customers flexibility for their compression and production and processing needs while limiting their capital requirements. During the year ended December 31, 2017, approximately 31% of our revenue and 70% of our gross margin was generated from contract operations. Our contract operations business is capital intensive. As of December 31, 2017, the net book value of property, plant and equipment associated with our contract operations business was $745.9 million. Aftermarket Services In our aftermarket services business, we sell parts and components and provide operations, maintenance, overhaul, upgrade, commissioning and reconfiguration services to customers outside of the U.S. who own their own compression, production, processing, treating and related equipment. Our services range from routine maintenance services and parts sales to the full operation and maintenance of customer-owned equipment. We generally enter into contracts with our operation and maintenance customers with initial terms ranging between two to four years, and in some cases, in excess of six years. In many instances, we are able to renew those contracts prior to the expiration of the initial term. We believe that we are particularly well qualified to provide these services because of our highly experienced operating personnel and technical and engineering expertise gained through providing similar services as part of our contract operations business. In addition, our aftermarket services business compliments our strategy to provide integrated infrastructure solutions to our customers because it enables us to continue to serve our customers after the sale of any assets or facilities manufactured through our product sales business. We seek to couple our aftermarket services with our product sales business to provide ongoing services to customers who buy equipment from us and also seek to sell those services to customers who have bought equipment from other companies. During the year ended December 31, 2017, approximately 9% of our revenue and 8% of our gross margin was generated from aftermarket services. Product Sales In our product sales business, we design, engineer, manufacture, install and sell natural gas compression packages as well as equipment used in the production, treating and processing of crude oil and natural gas primarily to major and independent oil and natural gas producers as well as national oil and natural gas companies in the countries where we operate. We offer a broad range of equipment designed to make crude oil and natural gas suitable for end use. We believe the broad range of products we sell through our global platform enables us to take advantage of the ongoing, worldwide energy infrastructure build-out. Our products include line heaters, oil and natural gas separators, glycol dehydration units, condensate stabilizers, dew point control plants, water treatment, mechanical refrigeration and cryogenic plants and skid-mounted production packages designed for both onshore and offshore production facilities. We sell standard production and processing equipment, which is used for processing wellhead production from onshore or shallow-water offshore platform production. In addition, we sell custom- engineered, built-to-specification production and processing equipment, including designing facilities comprised of a combination of our products integrated into a solution that meets our customers’ needs. Some of these projects are in remote areas and in developing countries with limited oil and natural gas industry infrastructure. To meet most customers’ rapid response requirements and minimize customer downtime, we maintain an inventory of standard products and longer lead-time components used to manufacture our products to our customers’ specifications. Typically, we expect our production and processing equipment backlog to be produced within a three to 24 month period. We also design, engineer, manufacture, sell and, in certain cases, install, skid-mounted natural gas compression equipment to meet standard or unique customer specifications. Generally, we assemble compressors sold to third parties according to each customer’s specifications. We purchase components for these compressors from third party suppliers including several major engine and compressor manufacturers in the industry. We also sell pre-engineered compressor units designed to maximize value and fast delivery to our customers. Typically, we expect our compressor equipment backlog to be produced within a three to 12 month period. During the year ended December 31, 2017, approximately 60% of our revenue and 22% of our gross margin was generated from product sales. As of December 31, 2017, our backlog in product sales was $461.0 million, all of which is expected to be recognized as revenue before December 31, 2018. Our product sales backlog consists of unfilled orders based on signed contracts and does not include potential product sales pursuant to letters of intent received from customers. Competitive Strengths We believe we have the following key competitive strengths: • Global platform and expansive service and product offerings positioned to capitalize on the global energy infrastructure build-out. Global oil and natural gas infrastructure continues to be built out, which provides us with opportunities for growth. We are well positioned to capitalize on increased opportunities in the U.S. and international markets. We believe our global customer base continues to invest in infrastructure projects based on longer-term fundamentals that are less tied to near-term commodity prices and that our size, geographic scope and broad customer base provide us with a unique advantage in meeting our customers’ needs and will allow us to capture future opportunities. We provide our customers with a broad variety of products and services in approximately 30 countries worldwide, including outsourced compression, production and processing services, natural gas compression, oil and natural gas production and processing equipment, water treatment solutions, installation services and integrated power generation. By offering a broad range of products and services that leverage our core strengths, we believe we provide unique integrated solutions that meet our customers’ needs. We believe the breadth and quality of our products and services, the depth of our customer relationships and our presence in many major oil and natural gas producing regions place us in a position to capture additional business on a global basis. • Complementary businesses enable us to offer customers integrated infrastructure solutions. We aim to provide our customers with a single source to meet their energy infrastructure needs and we believe we have the ability to serve our customers’ changing needs in a variety of ways. For customers that seek to manage their capital spending on energy infrastructure projects, we offer our full operations services through our contract operations business. For customers that prefer to develop and acquire their own infrastructure assets, we are able to sell equipment and facilities for their operations and, following the sale of our equipment, we can also provide commissioning, operations, maintenance, overhaul, upgrade and reconfiguration services through our aftermarket services. Furthermore, we combine our products into an integrated solution that we design, engineer, procure and, in some cases, construct on-site for sale to our customers. Because of the breadth of our products and our ability to deliver those products through our different delivery models, we believe we are able to provide the solution that is most suitable to our customers in the markets in which they operate. We believe this ability to provide our customers with a variety of products and services provides us with more business opportunities, as we are able to adjust the products and services we provide to reflect our customers’ changing needs. • High-quality products and services. We have built a network of high-quality energy infrastructure assets that are strategically deployed across our global platform. Through our history of operating a wide variety of products in many energy-producing markets around the world, we have developed the technical expertise and experience that we believe is required to understand the needs of our customers and to meet those needs through a range of products and services. These products and services include highly customized compression, production and processing solutions as well as standard products based on our expertise, in support of a range of projects, from those requiring quick completion to those that may take several years to fully develop. Additionally, our experience has enabled us to develop efficient systems and processes and a skilled workforce that allow us to provide high- quality services throughout international markets. We seek to continually improve our products and services to enable us to provide our customers with high-quality, comprehensive oil and natural gas infrastructure support worldwide. • Cash flows from our contract operations business are supported by long-term contracts. We provide contract operations services to customers located in approximately 15 countries. Within our contract operations business, we seek to enter into long-term contracts with a diverse collection of customers, including large integrated oil and natural gas companies and national energy companies. These contracts generally involve initial terms ranging from three to five years, and in some cases, in excess of 10 years, and typically require our customers to pay our monthly service fee even during periods of limited or disrupted oil or natural gas flows. Furthermore, our customer base includes several companies that are among the largest and most well-known companies within their respective regions throughout our global platform. • Experienced management team. We have an experienced and skilled management team with a long track record of driving growth through organic expansion and selective acquisitions. The members of our management team have strong relationships in the oil and gas industry and have operated through numerous commodity price cycles throughout our areas of operations. Members of our management team have spent a significant portion of their respective careers at highly regarded energy and manufacturing companies. • Well-balanced capital structure with sufficient liquidity. We intend to maintain a capital structure with an appropriate amount of leverage and the financial flexibility to invest in our operations and pursue attractive growth opportunities that we believe will increase the overall earnings and cash flow generated by our business. As of December 31, 2017, taking into account guarantees through letters of credit, we had undrawn capacity of $640.3 million under our revolving credit facility, of which $585.2 million was available for additional borrowings as a result of a covenant restriction included in our credit agreement. In addition, as of December 31, 2017, we had $49.1 million of cash and cash equivalents on hand. Business Strategies We intend to continue to capitalize on our competitive strengths to meet our customers’ needs through the following key strategies: • Strategically grow our business. Our primary strategic focus involves the growth of our business through expanding our product and services offerings by leveraging our portfolio of products and services. We intend to infuse technology and innovation into our existing midstream products and services while developing new product and service offerings in water treatment and integrated power generation. Additionally, our strategic focus includes targeting redevelopment opportunities in the U.S. energy market and expansions into new international markets benefiting from the global energy infrastructure build-out. We believe our diverse product and service portfolio allows us to readily respond to changes in industry and economic conditions and that our global footprint allows us to provide the prompt product availability our customers require. We have the ability to construct projects in new locations as needed to meet customer demand and to readily deploy our capital to construct new or supplemental projects that we build, own and operate on behalf of our customers through our contract operations business. In addition, we seek to provide our customers with integrated infrastructure solutions by combining product and service offerings across our businesses. We plan to supplement our organic growth with select acquisitions, partnerships and other commercial arrangements in key markets to further enhance our geographic reach, product offerings and other capabilities. We believe these arrangements will allow us to generate incremental revenues from existing and new customers and obtain greater market share. • Expand customer base and deepen relationships with existing customers. We believe the unique, broad range of services we offer, the quality of our products and services and our diverse geographic footprint position us to attract new customers and cross-sell our products and services to existing customers. In addition, we have significant experience and a long history of providing our products and services to our customers which, coupled with the technical expertise of our experienced personnel, enables us to understand and meet our customers’ needs, particularly as those needs develop and change over time. We intend to continue to devote significant business development resources to market our products and services, leverage existing relationships and expedite our growth potential. Additionally, we seek to evolve our products and services offerings by developing new technologies that will allow us to provide solutions to the critical midstream infrastructure needs of our customers. • Enhance our safety performance. We believe our safety performance and reputation help us to attract and retain customers and employees. We have adopted rigorous processes and procedures to facilitate our compliance with safety regulations and policies. We work diligently to meet or exceed applicable safety regulations, and intend to continue to focus on our safety monitoring function as our business grows and operating conditions change. • Continue to optimize our global platform, products and services and enhance our profitability. We regularly review and evaluate the quality of our operations, products and services and portfolio of our product and service offerings. This process includes assessing the quality of our performance and potential opportunities to create value for our customers. We believe the development and introduction of new technology into our existing products and services will create more value for us in the market place, which we believe will further differentiate us from our competitors. Additionally, we believe our ongoing focus on improving the quality of our operations, products and services results in greater satisfaction among our customers, which we believe results in greater profitability and value for our shareholders. Industry Overview Natural Gas Compression Our international compression business is comprised primarily of large horsepower compressors that are typically deployed in facilities comprised of several compressors on one site. A significant portion of this business involves comprehensive projects that require the design, engineering, manufacture, delivery and installation of several compressors on one site coupled with related natural gas treating and processing equipment. We are able to serve our customers’ needs for such projects through our product sales business and with follow-on services from our aftermarket services business, or through the provision of our contract operations services. Natural gas compression is a mechanical process whereby the pressure of a given volume of natural gas is increased to a desired pressure for transportation from one point to another and is essential to the production and transportation of natural gas. Compression is typically required several times during the natural gas production and transportation cycle, including (i) at the wellhead, (ii) throughout gathering and distribution systems, (iii) into and out of processing and storage facilities and (iv) along pipelines. Natural gas compression can also be used to re-inject associated gas into producing wells to provide enhanced oil recovery. Production and Processing Crude oil and natural gas are generally not marketable as produced at the wellhead and must be processed or treated before they can be transported to market. Production and processing equipment is used to separate and treat oil and natural gas as they are produced to achieve a marketable quality of product. Production processing typically involves the separation of oil and natural gas and the removal of contaminants or the separation of marketable liquids from the gas stream prior to transportation. The end result is “pipeline” or “sales” quality oil and natural gas. Further processing or refining is almost always required before oil or natural gas is suitable for use as fuel or feedstock for petrochemical production. Production processing normally takes place in the “upstream” and “midstream” segments, while refining and petrochemical processing is referred to as the “downstream” segment. Wellhead or upstream production and processing equipment include a wide and diverse range of products. We manufacture and stock standard production equipment based on historical product mix and expected customer purchases following general trends of oil and natural gas production. In addition, we sell custom-engineered, built-to-specification production and processing equipment. We also provide integrated solutions comprised of a combination of our products into a single offering, which typically consists of much larger equipment packages than standard equipment and is generally used in much larger scale production operations. The custom equipment segment is primarily driven by global economic trends, and the specifications for purchased equipment can vary significantly. Technology, engineering capabilities, project management, available manufacturing space and quality control standards are the key drivers in the custom equipment segment. Outsourcing Natural gas producers, transporters and processors choose to outsource their operations due to the benefits and flexibility of contract operations. In particular, we believe outsourcing compression, production and processing operations to us offers customers: • • • access to our specialized personnel and technical skills, including engineers and field service and maintenance employees, which we believe generally leads to improved production rates and increased throughput and higher revenues; the ability to increase their profitability by transporting or producing a higher volume of natural gas through decreased equipment downtime and reduced operating, maintenance and equipment costs by allowing us, as the service provider, to efficiently manage their operations; and the flexibility to deploy their capital on projects more directly related to their primary business by reducing their investment in compression, production and processing equipment and related maintenance capital requirements. Oil and Natural Gas Industry Cyclicality and Volatility Changes in oil and natural gas exploration and production spending normally result in changes in demand for our products and services. However, we believe our contract operations business is less impacted by commodity prices than certain other energy service products and services because compression, production and processing services are necessary for oil and natural gas to be delivered from the wellhead to end users. Furthermore, our contract operations business is tied primarily to oil and natural gas production and consumption, which are generally less cyclical in nature than exploration activities. Demand for oil and natural gas is cyclical and subject to fluctuations. This is primarily because the industry is driven by commodity demand and corresponding price movements. When oil and natural gas price increases occur, producers typically increase their capital expenditures, which generally results in greater activity levels and revenues for equipment providers to the oil and gas industry. During periods of lower oil or natural gas prices, producers typically decrease their capital expenditures, which generally results in lower activity levels and revenues for equipment providers to the oil and gas industry. Seasonal Fluctuations Our results of operations have not historically reflected material seasonal tendencies and we do not believe that seasonal fluctuations will have a material impact on us in the foreseeable future. Markets, Customers and Competition Our global customer base consists primarily of companies engaged in all aspects of the oil and natural gas industry, including large integrated oil and natural gas companies, national energy companies, independent producers and natural gas processors, gatherers and pipeline operators. During the years ended December 31, 2017 and 2015, Archrock and its affiliates accounted for approximately 12% and 11% of our total revenue, respectively. During the year ended December 31, 2016, Petroleo Brasileiro S.A. (“Petrobras”) accounted for approximately 10% of our total revenue. No other customer accounted for more than 10% of our revenue in 2017, 2016 and 2015. The loss of our business with Petrobras or Archrock, unless offset by additional sales to other customers, or the inability or failure of Petrobras or Archrock to meet its payment obligations could have an adverse effect on our business, results of operations and financial condition. See Note 17 to the Financial Statements for further discussion on transactions with affiliates. We currently operate in approximately 30 countries. We have manufacturing facilities in the U.S., Singapore and the United Arab Emirates and offices in the major oil and gas regions around the world. The businesses in which we operate are highly competitive. Overall, we experience considerable competition from companies that may be able to more quickly adapt to changes within our industry and changes in economic conditions as a whole and to more readily take advantage of available opportunities. We believe we are competitive with respect to price, equipment availability, customer service, flexibility in meeting customer needs, technical expertise, quality and reliability of our compression, production and processing equipment and related services. We face vigorous competition throughout our businesses, with some firms competing with us in multiple businesses. In our product sales business, we have different competitors in the standard and custom-engineered equipment segments. Competitors in the standard equipment segment include several large companies and a large number of small, regional fabricators. Our competition in the custom-engineered segment consists mainly of larger companies with the ability to provide integrated projects and product support after the sale. We expect to face increased competition as we seek to diversify our customer base and increase utilization of our service offerings. The separation and distribution agreement from the Spin-off contains certain noncompetition provisions addressing restrictions on our ability to provide compression contract operations and aftermarket services in the U.S. and on Archrock’s ability to provide compression contract operations and aftermarket services outside of the U.S. and product sales to customers worldwide that expire on November 3, 2018, subject to certain exceptions. Sources and Availability of Raw Materials We manufacture natural gas compression and oil and natural gas production and processing equipment to provide contract operations services and to sell to third parties from components which we acquire from a wide range of vendors. These components represent a significant portion of the cost of our compressor and production and processing equipment products. Increases in raw material costs cannot always be offset by increases in our products’ sales prices. While many of our materials and components are available from multiple suppliers at competitive prices, we obtain some of the components, including compressors and engines, used in our products from a limited group of suppliers. We occasionally experience long lead times for components, including compressors and engines, from our suppliers and, therefore, we may at times make purchases in anticipation of future orders. Environmental and Other Regulations Government Regulation Our operations are subject to stringent and complex U.S. federal, state, local and international laws and regulations that could have a material impact on our operations or financial condition. Our operations are regulated under a number of laws governing, among other things, discharges of substances into the air, ground and regulated waters, the generation, transportation, treatment, storage and disposal of hazardous and non-hazardous substances, disclosure of information about hazardous materials used or produced in our operations, and occupational health and safety. Compliance with these environmental laws and regulations may expose us to significant costs and liabilities and cause us to incur significant capital expenditures in our operations. Failure to comply with these laws and regulations may result in the assessment of administrative, civil and criminal penalties, imposition of investigatory and remedial obligations, and the issuance of injunctions delaying or prohibiting operations. In certain circumstances, laws may impose strict, joint and several liability without regard to fault or the legality of the original conduct on classes of persons who are considered to be responsible for the release of hazardous substances into the environment. In addition, it is not uncommon for third parties to file claims for personal injury, property damage and recovery of response costs allegedly caused by hazardous substances or other pollutants released into the environment. We currently own or lease, and in the past have owned or leased, a number of properties that have been used in support of our operations for a number of years. Although we have utilized operating and disposal practices that were standard in the industry at the time, hydrocarbons, hazardous substances, or other regulated wastes may have been disposed of, or released, on or under the properties owned by us, leased by us or other locations where such materials have been taken for disposal by companies sub-contracted by us. In addition, many of these properties have been previously owned or operated by third parties whose treatment and disposal or release of hydrocarbons, hazardous substances or other regulated wastes were not under our control. These properties and the materials released or disposed thereon may be subject to various laws that could require us to remove or remediate historical property contamination, or to perform certain operations to prevent future contamination. We are not currently under any order requiring that we undertake or pay for any cleanup activities. However, we cannot provide any assurance that we will not receive any such order in the future. The clear trend in environmental regulation is to place more restrictions on activities that may affect the environment, and thus, any changes in these laws and regulations that result in more stringent and costly waste handling, storage, transport, disposal, emission or remediation requirements could have a material adverse effect on our results of operations and financial position. Employees As of December 31, 2017, we had approximately 4,500 employees. Many of our employees outside of the U.S. are covered by collective bargaining agreements. We generally consider our relationships with our employees to be satisfactory. Available Information Our website address is www.exterran.com.

Risk Factors As described in Part I (“Disclosure Regarding Forward-Looking Statements”), this report contains forward-looking statements regarding us, our business and our industry. The risk factors described below, among others, could cause our actual results to differ materially from the expectations reflected in the forward-looking statements. If any of the following risks actually occurs, our business, financial condition, results of operations and cash flows could be negatively impacted. Risks Related to Our Business and Industry Low oil and natural gas prices could depress or reduce demand or pricing for our natural gas compression and oil and natural gas production and processing equipment and services and, as a result, adversely affect our business. Our results of operations depend upon the level of activity in the global energy market, including oil and natural gas development, production, processing and transportation. Oil and natural gas exploration and development activity and the number of well completions typically decline when there is a sustained reduction in oil or natural gas prices or significant instability in energy markets. Even the perception of longer-term lower oil or natural gas prices by oil and natural gas exploration, development and production companies can result in their decision to cancel, reduce or postpone major expenditures or to reduce or shut in well production. Oil and natural gas prices and the level of drilling and exploration activity can be volatile. In periods of volatile commodity prices, the timing of any change in activity levels by our customers is difficult to predict. As a result, our ability to project the anticipated activity level for our business, and particularly our product sales segment may be limited. During periods of lower oil or natural gas prices, our customers typically decrease their capital expenditures, which generally results in lower activity levels. A reduction in demand for our products and services could force us to reduce our pricing substantially, which could have a material adverse effect on our business, financial condition, results of operations and cash flows. For example, due to the low oil and natural gas price environment during 2015 and the majority of 2016, our customers sought to reduce their capital and operating expenditure requirements, and as a result, the demand and pricing for the equipment we manufacture was adversely impacted. Moreover, a reduction in demand for our products and services could result in our customers seeking to preserve capital by canceling contracts, canceling or delaying scheduled maintenance of their existing natural gas compression and oil and natural gas production and processing equipment, ceasing commitments for new contract operations service contracts or new compression and oil and natural gas production and processing equipment, or canceling or delaying orders for our products and services, any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows. The erosion of the financial condition of our customers could adversely affect our business. Many of our customers finance their exploration and development activities through cash flows from operations, the incurrence of debt or the issuance of equity. During times when the oil or natural gas markets weaken, our customers are more likely to experience a downturn in their financial condition. A reduction in borrowing bases under reserve-based credit facilities, the lack of availability of debt or equity financing or other factors that negatively impact our customers’ financial condition could result in our customers seeking to preserve capital by reducing prices under existing contracts or cancelling contracts with us, determining not to renew contracts with us, cancelling or delaying scheduled maintenance of their existing natural gas compression and oil and natural gas production and processing equipment, determining not to enter into contract operations agreements or not to purchase new compression and oil and natural gas production and processing equipment, or determining to cancel or delay orders for our products and services. Any such action by our customers would reduce demand for our products and services. Reduced demand for our products and services could adversely affect our business, financial condition, results of operations and cash flows. In addition, in the event of the financial failure of a customer, we could experience a loss on all or a portion of our outstanding accounts receivable associated with that customer. Failure to timely and cost-effectively execute on larger projects could adversely affect our business. Some of our projects have a relatively larger size and scope than the majority of our projects, which can translate into more technically challenging conditions or performance specifications for our products and services. Contracts with our customers for these projects typically specify delivery dates, performance criteria and penalties for our failure to perform. Any failure to estimate the cost of and execute these larger projects in a timely and cost effective manner could have a material adverse effect on our business, financial condition, results of operations and cash flows. We may incur losses on fixed-price contracts, which constitute a significant portion of our business. In connection with projects and services performed under fixed-price contracts, we generally bear the risk of cost over-runs, operating cost inflation, labor availability and productivity, and supplier and subcontractor pricing and performance, unless additional costs result from customer-requested change orders. Under both our fixed-price contracts and our cost-reimbursable contracts, we may rely on third parties for many support services, and we could be subject to liability for their failures. Any failure to accurately estimate our costs and the time required for a fixed-price project at the time we enter into a contract could have a material adverse effect on our business, financial condition, results of operations and cash flows. Our operations in international markets are subject to many risks. Our contract operations and aftermarket services businesses, and a portion of our product sales business, are conducted in countries outside the U.S. We currently operate in approximately 30 countries. With respect to any particular country in which we operate, the risks inherent in our activities may include the following, the occurrence of any of which could have a material adverse effect on our business, financial condition, results of operations and cash flows: • • difficulties in managing international operations, including our ability to timely and cost effectively execute projects; unexpected changes in regulatory requirements, laws or policies by foreign agencies or governments; • work stoppages; • • • • • • • • • • • • • • • • training and retaining qualified personnel in international markets; the burden of complying with multiple and potentially conflicting laws and regulations; tariffs and other trade barriers; actions by governments or national oil companies that result in the nullification or renegotiation on less than favorable terms of existing contracts, or otherwise result in the deprivation of contractual rights, and other difficulties in enforcing contractual obligations; governmental actions that: result in restricting the movement of property or that impede our ability to import or export parts or equipment; require a certain percentage of equipment to contain local or domestic content; or require certain local or domestic ownership, control or employee ratios in order to do business in or obtain special incentives or treatment in certain jurisdictions; potentially longer receipt of payment cycles; changes in political and economic conditions in the countries in which we operate, including general political unrest, the nationalization of energy related assets, civil uprisings, riots, kidnappings, violence associated with drug cartels and terrorist acts; potentially adverse tax consequences or tax law changes; currency controls or restrictions on repatriation of earnings; expropriation, confiscation or nationalization of property without fair compensation; the risk that our international customers may have reduced access to credit because of higher interest rates, reduced bank lending or a deterioration in our customers’ or their lenders’ financial condition; complications associated with installing, operating and repairing equipment in remote locations; limitations on insurance coverage; inflation; the geographic, time zone, language and cultural differences among personnel in different areas of the world; and difficulties in establishing new international offices and the risks inherent in establishing new relationships in foreign countries. In addition, we may expand our business in international markets where we have not previously conducted business. The risks inherent in establishing new business ventures, especially in international markets where local customs, laws and business procedures present special challenges, may affect our ability to be successful in these ventures or avoid losses that could have a material adverse effect on our business, financial condition, results of operations and cash flows. Our contract operations segment is dependent on companies that are controlled by the government in which it operates. The countries with our largest contract operations businesses include Mexico, Brazil and Argentina. We generate a significant portion of our revenue in these countries from national oil companies, including Yacimientos Petroliferos Fiscales in Argentina, Petroleos Mexicanos in Mexico and Petrobras in Brazil. Contracts with national oil companies may expose us to greater commercial, political and operational risks than we assume in other contracts. Our ability to resolve disputes or enforce contractual provisions may be negatively impacted by the significant bargaining leverage that national oil companies have over us. If our national oil company customers cancel some of our contracts and we are unable to secure new contracts on a timely basis and on substantially similar terms, or if a number of our contracts are renegotiated, it could adversely affect our business, financial position, results of operations or cash flows. We are exposed to exchange rate fluctuations in the international markets in which we operate. We operate in many international countries and anticipate that there will be instances in which costs and revenues will not be exactly matched with respect to currency denomination. Gains and losses from the remeasurement of assets and liabilities that are receivable or payable in currencies other than our subsidiaries’ functional currency are included in our statements of operations. In addition, currency fluctuations cause the U.S. dollar value of our international results of operations and net assets to vary with exchange rate fluctuations. A decrease in the value of any of these currencies relative to the U.S. dollar could have a negative impact on our business, financial condition, results of operations or cash flows. As we expand geographically, we may experience economic loss and a negative impact on earnings or net assets solely as a result of foreign currency exchange rate fluctuations. In the future, we may utilize derivative instruments to manage the risk of fluctuations in foreign currency exchange rates that could potentially impact our future earnings and forecasted cash flows. However, the markets in which we operate could restrict the removal or conversion of the local or foreign currency, resulting in our inability to hedge against some or all of these risks. See further discussion of foreign exchange risks under Item 7A “Quantitative and Qualitative Disclosures about Market Risk” included elsewhere in this Annual Report. We are involved in governmental and internal investigations, which are costly to conduct, may result in substantial financial and other penalties, and could adversely affect our business, financial condition and results of operations. In March 2016, the Audit Committee of the Board of Directors retained legal counsel to conduct an internal investigation related to the application of percentage-of-completion accounting principles to specific Belleli EPC product sales projects. Our Belleli EPC business had historically been comprised of engineering, procurement and construction for the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants in the Middle East (referred to as “Belleli EPC” or the “Belleli EPC business” herein). On April 26, 2016, we filed a Form 8-K reporting the errors and possible irregularities at Belleli EPC. Contemporaneously with filing the Form 8-K, we self-reported these issues to the SEC. We continue to cooperate with the SEC in its ongoing investigation of this matter, which has included responding to a subpoena for documents related to the circumstances giving rise to the restatement as well as documents related to our compliance with the U.S. Foreign Corrupt Practices Act (“FCPA”), which were also provided to the Department of Justice (“DOJ”) at its request. We also have made the SEC and DOJ aware of our internal investigation regarding previously restated non-income- based tax receivables due to us from the Brazilian government. We could be subject to stockholder or other actions, or further regulatory actions, in connection with these issues in the future. The SEC staff has notified us that they have concluded their investigation concerning our compliance with the FCPA and that they do not intend to recommend an enforcement action concerning our compliance with the FCPA. The DOJ has similarly informed us that it does not intend to proceed with any further investigation or enforcement. The SEC’s investigation related to the circumstances giving rise to the restatement is continuing, and we are presently unable to predict the duration, scope or results or whether the SEC will commence any legal action. If we are found to have violated securities laws or other federal statutes, we may be subject to criminal and civil penalties and other remedial measures, including, but not limited to injunctive relief, disgorgement, civil and criminal fines and penalties, modifications to business practices including the termination or modification of existing business relationships, modifications of compliance programs and the retention of a monitor to oversee compliance. The imposition of any of these sanctions or remedial measures could have a material adverse impact on our reputation, business, results of operations, financial condition, liquidity and stock price. The termination of or any price reductions under certain of our contract operations services contracts could have a material impact on our business. The termination of or a demand by our customers to reduce prices under certain of our contract operations services contracts may lead to a reduction in our revenues and net income, which could have a material adverse effect upon our business, financial condition, results of operations and cash flows. In addition, we may be unable to renew, or enter into new, contracts with customers on favorable commercial terms, if at all. To the extent we are unable to renew our existing contracts or enter into new contracts on terms that are favorable to us or to successfully manage our overall contract mix over time, our business, results of operations and cash flows may be adversely impacted. Product sales backlog may be subject to unexpected adjustments and cancellations. The revenues projected in our product sales backlog may not be realized or, if realized, may not result in profits. Due to potential project cancellations or changes in project scope and schedule, we cannot predict with certainty when or if backlog will be performed. In addition, even where a project proceeds as scheduled, it is possible that contracted parties may default and fail to pay amounts owed to us or poor project performance could increase the cost associated with a project. Delays, suspensions, cancellations, payment defaults, scope changes and poor project execution could materially reduce the revenues and reduce or eliminate profits that we actually realize from projects in backlog. We may be at greater risk of delays, suspensions and cancellations during periods of low oil and natural gas prices. Reductions in our product sales backlog due to cancellation or modification by a customer or for other reasons may adversely affect, potentially to a material extent, the revenues and earnings we actually receive from contracts included in our backlog. Many of the contracts in our product sales backlog provide for cancellation fees in the event customers cancel projects. These cancellation fees usually provide for reimbursement of our out-of-pocket costs, revenues for work performed prior to cancellation and a varying percentage of the profits we would have realized had the contract been completed. However, we typically have no contractual right upon cancellation to the total revenue reflected in our backlog. Projects may remain in our backlog for extended periods of time. If we experience significant project terminations, suspensions or scope adjustments to contracts reflected in our backlog, our financial condition, results of operations and cash flows may be adversely impacted. From time to time, we are subject to various claims, litigation and other proceedings that could ultimately be resolved against us, requiring material future cash payments or charges, which could impair our financial condition or results of operations. The size, nature and complexity of our business make us susceptible to various claims, both in litigation and binding arbitration proceedings. We are currently, and may in the future become, subject to various claims, which, if not resolved within amounts we have accrued, could have a material adverse effect on our financial position, results of operations or cash flows. Similarly, any claims, even if fully indemnified or insured, could negatively impact our reputation among our customers and the public, and make it more difficult for us to compete effectively or obtain adequate insurance in the future. We depend on particular suppliers and may be vulnerable to product shortages and price increases. Some of the components used in our products are obtained from a single source or a limited group of suppliers. Our reliance on these suppliers involves several risks, including price increases, quality and a potential inability to obtain an adequate supply of required components in a timely manner. We do not have long-term contracts with some of these sources, and the partial or complete loss of certain of these sources could have a negative impact on our results of operations and could damage our customer relationships. Further, a significant increase in the price of one or more of these components could have a negative impact on our results of operations. We face significant competitive pressures that may cause us to lose market share and harm our financial performance. Our businesses face intense competition and have low barriers to entry. Our competitors may be able to adapt more quickly to technological changes within our industry and changes in economic and market conditions and more readily take advantage of acquisitions and other opportunities. Our ability to renew or replace existing contract operations service contracts with our customers at rates sufficient to maintain current revenue and cash flows could be adversely affected by the activities of our competitors. If our competitors substantially increase the resources they devote to the development and marketing of competitive products, equipment or services or substantially decrease the price at which they offer their products, equipment or services, we may not be able to compete effectively. In addition, we could face significant competition from new entrants into the compression services and product sales businesses. Some of our existing competitors or new entrants may expand or develop new processing, treating and compression equipment that would create additional competition for the products, equipment or services we provide to our customers. Our ability to manage and grow our business effectively may be adversely affected if we lose management or operational personnel. We believe that our ability to hire, train and retain qualified personnel will continue to be challenging and important. The supply of experienced operational and field personnel, in particular, decreases as other energy and manufacturing companies’ needs for the same personnel increase. Our ability to grow and to continue our current level of service to our customers will be adversely impacted if we are unable to successfully hire, train and retain these important personnel. Our employees work on projects that are inherently dangerous. If we fail to maintain safe work sites, we can be exposed to significant financial losses and reputational harm. Safety is a leading focus of our business, and our safety record is critical to our reputation and is of paramount importance to our employees, customers and stockholders. However, we often work on large-scale and complex projects which can place our employees and others near large mechanized equipment, moving vehicles, dangerous processes and in challenging environments. Although we have a functional group whose primary purpose is to implement effective quality, health, safety, environmental and security procedures throughout our company, if we fail to implement effective safety procedures, our employees and others may become injured, disabled or lose their lives, our projects may be delayed and we may be exposed to litigation or investigations. Unsafe conditions at project work sites also have the potential to increase employee turnover, increase project costs and raise our operating costs. Additionally, many of our customers require that we meet certain safety criteria to be eligible to bid for contracts and our failure to maintain adequate safety standards could result in reduced profitability, or lost project awards or customers. Any of the foregoing could result in financial losses or reputational harm, which could have a material adverse impact on our business, financial condition and results of operations. Our operations entail inherent risks that may result in substantial liability. We do not insure against all potential losses and could be seriously harmed by unexpected liabilities. Our operations entail inherent risks, including equipment defects, malfunctions and failures and natural disasters, which could result in uncontrollable flows of natural gas or well fluids, fires and explosions. These risks may expose us, as an equipment operator and developer, to liability for personal injury, wrongful death, property damage, pollution and other environmental damage. The insurance we carry against many of these risks may not be adequate to cover our claims or losses. In addition, we are substantially self-insured for workers’ compensation, employer’s liability, property, auto liability, general liability and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Further, insurance covering the risks we expect to face or in the amounts we desire may not be available in the future or, if available, the premiums may not be commercially justifiable. If we were to incur substantial liability and such damages were not covered by insurance or were in excess of policy limits, or if we were to incur liability at a time when we are not able to obtain liability insurance, our business, financial condition and results of operations could be negatively impacted. We may be subject to risks arising from changes in technology. The supply chains in which we operate are subject to technological changes and changes in customer requirements. We may not successfully develop or implement new or modified types of products or technologies that may be required by our customers in the future. Further, the development of new technologies by competitors that may compete with our technologies could reduce demand for our products and affect our financial performance. Should we not be able to maintain or enhance the competitive values of our products or develop and introduce new products or technologies successfully, or if new products or technologies fail to generate sufficient revenues to offset research and development costs, our business, financial condition and operating results could be materially adversely affected. Cyber-attacks or terrorism could affect our business. We may be adversely affected by problems such as cyber-attacks, computer viruses or terrorism that may disrupt our operations and harm our operating results. Our industry requires the continued operation of sophisticated information technology systems and network infrastructure. Despite our implementation of security measures, our technology systems are vulnerable to disability or failures due to hacking, viruses, acts of war or terrorism and other causes. If our information technology systems were to fail and we were unable to recover in a timely way, we might be unable to fulfill critical business functions, which could have a material adverse effect on our business, financial condition and results of operations. In addition, our assets may be targets of terrorist activities that could disrupt our ability to service our customers. We may be required by our regulators or by the future terrorist threat environment to make investments in security that we cannot currently predict. The implementation of security guidelines and measures and maintenance of insurance, to the extent available, could increase costs. These types of events could have a material adverse effect on our business and results of operations. In addition, these types of events could require significant management attention and resources, and could adversely affect our reputation among customers and the public. We are subject to a variety of governmental regulations; failure to comply with these regulations may result in administrative, civil and criminal enforcement measures and changes in these regulations could increase our costs or liabilities. We are subject to a variety of U.S. federal, state, local and international laws and regulations relating to, for example, export controls, currency exchange, labor and employment and taxation. Many of these laws and regulations are complex, change frequently, are becoming increasingly stringent, and the cost of compliance with these requirements can be expected to increase over time. From time to time, as part of our operations we may be subject to compliance audits by regulatory authorities in the various countries in which we operate. Our failure to comply with these laws and regulations may result in a variety of administrative, civil and criminal enforcement measures, including assessment of monetary penalties, imposition of remedial requirements and issuance of injunctions as to future compliance, any of which may have a negative impact on our financial condition, profitability and results of operations. Our international operations require us to comply with U.S. and international laws and regulations, including those involving anti-bribery and anti-corruption. For example, the FCPA and similar laws and regulations prohibit improper payments to foreign officials for the purpose of obtaining or retaining business or gaining any business advantage. We operate in many parts of the world that experience high levels of corruption, and our business brings us in frequent contact with foreign officials. Our compliance policies and programs mandate compliance with all applicable anti-corruption laws but may not be completely effective in ensuring our compliance. Our training and compliance program and our internal control policies and procedures may not always protect us from violations committed by our employees or agents. If we undergo an investigation of potential violations of anti-corruption laws or if we fail to comply with these laws, we may incur significant legal expenses or be subject to criminal and civil penalties and other sanctions and remedial measures, which could have a material adverse impact on our reputation, business, financial condition, results of operations and liquidity. We also are subject to other laws and regulations governing our operations, including regulations administered by the U.S. Department of Treasury’s Office of Foreign Asset Control and various non-U.S. government entities, including applicable export control regulations, economic sanctions on countries and persons and customs requirements. Trade control laws are complex and constantly changing. Our compliance policies and programs increase our cost of doing business and may not work effectively to ensure our compliance with trade control laws. If we undergo an investigation of potential violations of trade control laws by U.S. or foreign authorities or if we fail to comply with these laws, we may incur significant legal expenses or be subject to criminal and civil penalties and other sanctions and remedial measures, which could have a material adverse impact on our reputation, business, financial condition and results of operations. Tax legislation and administrative initiatives or challenges to our tax positions could adversely affect our results of operations and financial condition. We operate in locations throughout the U.S. and internationally and, as a result, we are subject to the tax laws and regulations of U.S. federal, state, local and foreign governments. From time to time, various legislative or administrative initiatives may be proposed that could adversely affect our tax positions. In addition, U.S. federal, state and local and foreign tax laws and regulations are extremely complex and subject to varying interpretations. Moreover, economic and political pressures to increase tax revenue in various jurisdictions may make resolving tax disputes favorably more difficult. There can be no assurance that our tax positions will not be challenged by relevant tax authorities or that we would be successful in any such challenge. Changes to our tax positions resulting from tax legislation and administrative initiatives or challenges from taxing authorities could adversely affect our results of operations and financial condition. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Reform Act”). The Tax Reform Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) eliminating the corporate alternative minimum tax (“AMT”) and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax, a new minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. Guidance under U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Reform Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. While we recorded provisional estimates of the impact of the Tax Reform Act, the final impact may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the government and actions we may take as a result of these enacted tax laws. We are continuing to analyze additional information to determine the final impact as well as other impacts of the Tax Reform Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our 2018 financial statements. U.S. federal, state and local legislative and regulatory initiatives relating to hydraulic fracturing as well as governmental reviews of such activities could result in increased costs and additional operating restrictions or delays in the completion of oil and natural gas wells, and adversely affect demand for our products. Hydraulic fracturing is an important and common practice that is used to stimulate production of natural gas and/or oil, from dense subsurface rock formations. Hydraulic fracturing involves the injection of water, sand or alternative proppant and chemicals under pressure into target geological formations to fracture the surrounding rock and stimulate production. Hydraulic fracturing is typically regulated by state agencies, but recently, there has been increased public concern regarding an alleged potential for hydraulic fracturing to adversely affect drinking water supplies, and proposals have been made to enact separate U.S. federal, state and local legislation that would increase the regulatory burden imposed on hydraulic fracturing. For example, at the U.S. federal level, the U. S. Environmental Protection Agency (“EPA”) issued an Advance Notice of Proposed Rulemaking to collect data on chemicals used in hydraulic fracturing operations under Section 8 of the Toxic Substances Control Act, and proposed regulations under the CWA governing wastewater discharges from hydraulic fracturing and certain other natural gas operations. Also, the U.S. Department of the Interior released a final rule that updates existing regulation of hydraulic fracturing activities on U.S. federal lands, including requirements for chemical disclosure, wellbore integrity and handling of flowback water. The final rule was expected to be effective on June 24, 2015, but, on September 30, 2015, a federal district court issued a preliminary injunction preventing implementation of the rule. In addition, several governmental reviews are underway that focus on environmental aspects of hydraulic fracturing activities. In June 2015, the EPA released its draft report on the potential impacts of hydraulic fracturing on drinking water resources, which concluded that hydraulic fracturing activities have not led to widespread, systemic impacts on drinking water sources in the U.S., although there are above and below ground mechanisms by which hydraulic fracturing activities have the potential to impact drinking water sources. The draft report is expected to be finalized after a public comment period and a formal review by EPA’s Science Advisory Board. In addition, the White House Council on Environmental Quality is coordinating an administration-wide review of hydraulic fracturing practices. The results of this study or similar governmental reviews could spur initiatives to further regulate hydraulic fracturing under the Safe Drinking Water Act of 1974 or otherwise. At the state level, several states have adopted or are considering legal requirements that could impose more stringent permitting, disclosure, and well construction requirements on hydraulic fracturing activities. For example in May 2013, the Texas Railroad Commission adopted new rules governing well casing, cementing and other standards for ensuring that hydraulic fracturing operations do not contaminate nearby water resources. Local governments may also seek to adopt ordinances within their jurisdictions regulating the time, place and manner of, or prohibiting the performance of, drilling activities in general or hydraulic fracturing activities in particular. If new or more stringent federal, state or local legal restrictions relating to the hydraulic fracturing process are adopted in areas where our natural gas exploration and production customers operate, those customers could incur potentially significant added costs to comply with such requirements, experience delays or curtailment in the pursuit of exploration, development or production activities and perhaps even be precluded from drilling wells. Any such restrictions could reduce demand for our products, and as a result could have a material adverse effect on our business, financial condition, results of operations and cash flows. The inability to acquire adequate supplies of water for our or our customers’ operations or the inability to dispose of or recycle the water we or our customers’ use economically and in an environmentally safe manner could result in increased costs and additional operating restrictions or delays in the completion of oil and natural gas wells, and adversely affect demand for our products. Oil and gas development activities require the use of water. For example, the hydraulic fracturing process to produce commercial quantities of oil and natural gas from many reservoirs requires the use and disposal of significant quantities of water. In certain areas, there may be a scarcity of water for drilling activities due to various factors, including insufficient local aquifer capacity or government regulations restricting the use of water. Our customers’ inability to secure sufficient amounts of water, or our or our customers’ inability to dispose of or recycle the water used in operations, could adversely impact our or our customers’ operations in certain areas. The imposition of new environmental initiatives and regulations, could further restrict our or our customers’ ability to conduct certain operations disposal of waste, including, but not limited to, produced water, drilling fluids and other materials associated with the exploration, development or production of oil and natural gas. Any such restrictions could reduce demand for our products, and as a result could have a material adverse effect on our business, financial condition, results of operations and cash flows. We are subject to a variety of environmental, health and safety regulations. Failure to comply with these regulations may result in administrative, civil and criminal enforcement measures and changes in these regulations could increase our costs or liabilities. We are subject to a variety of U.S. federal, state, local and international laws and regulations relating to the environment, and worker health and safety. These laws and regulations are complex, change frequently, are becoming increasingly stringent, and the cost of compliance with these requirements can be expected to increase over time. Failure to comply with these laws and regulations may result in administrative, civil and criminal enforcement measures, including assessment of monetary penalties, imposition of remedial requirements and issuance of injunctions as to future compliance. Certain of these laws also may impose joint and several and strict liability for environmental contamination, which may render us liable for remediation costs, natural resource damages and other damages as a result of our conduct that may have been lawful at the time it occurred or the conduct of, or conditions caused by, prior owners or operators or other third parties. In addition, where contamination may be present, it is not uncommon for neighboring land owners and other third parties to file claims for personal injury, property damage and recovery of response costs. Remediation costs and other damages arising as a result of environmental laws and regulations, and costs associated with new information, changes in existing environmental laws and regulations or the adoption of new environmental laws and regulations could be substantial and could negatively impact our financial condition, profitability and results of operations. We may need to apply for or amend facility permits or licenses from time to time with respect to storm water or wastewater discharges, waste handling, or air emissions relating to manufacturing activities or equipment operations, which subjects us to new or revised permitting conditions. These permits and authorizations may contain numerous compliance requirements, including monitoring and reporting obligations and operational restrictions, such as emission limits, which may be onerous or costly to comply with. Given the large number of facilities in which we operate, and the numerous environmental permits and other authorizations that are applicable to our operations, we may occasionally identify or be notified of technical violations of certain requirements existing in various permits or other authorizations. Occasionally, we have been assessed penalties for our non-compliance, and we could be subject to such penalties in the future. The modification or interpretation of existing environmental, health and safety laws or regulations, the more vigorous enforcement of existing laws or regulations, or the adoption of new laws or regulations may also negatively impact oil and natural gas exploration and production, gathering and pipeline companies, including our customers, which in turn could have a negative impact on us. Global climate change is an increased international concern and could increase operating costs or reduce the demand for our products and services. There has been an increased focus in the last several years on climate change and the possible role that emissions of greenhouse gases such as carbon dioxide and methane play in climate change. In the U.S., the EPA has begun to regulate greenhouse gas emissions under the federal Clean Air Act and regulatory agencies and legislative bodies in other countries where we operate have adopted greenhouse gas emission reduction programs. The adoption of new or more stringent legislation or regulatory programs restricting greenhouse gas emissions could require us to incur higher operating costs or increase the cost of, and thus reduce the demand for, the hydrocarbon products of our customers. These increased costs or reduced demand could have an adverse effect on our business, profitability or results of operations. Further, some scientists have concluded that increasing greenhouse gas concentrations in the atmosphere may produce physical effects, such as increased severity and frequency of storms, droughts, floods and other climate events. To the extent there are significant changes in the Earth’s climate in the markets we serve or the areas where our assets reside, we could incur increased expenses, our operations could be materially impacted, and demand for our products could fall. Demand for our products may also be adversely affected by conservation plans and efforts undertaken in response to global climate change, including plans developed in connection with the Paris climate conference in December 2015. Many governments also provide, or may in the future provide, tax advantages and other subsidies to support the use and development of alternative energy technologies. Our operations and the demand for our products or our customers’ products could be materially impacted by the development and adoption of these technologies. Risks Related to Our Level of Indebtedness Our outstanding debt obligations could limit our ability to fund future growth and operations and increase our exposure to risk during adverse economic conditions. At December 31, 2017, we had approximately $375.0 million under our 8.125% senior unsecured notes due 2025 (the “2017 Notes”). We did not have any borrowings under our revolving credit facility as of December 31, 2017. Many factors, including factors beyond our control, may affect our ability to make payments on our outstanding indebtedness. These factors include those discussed elsewhere in these Risk Factors and those listed in the Disclosure Regarding Forward-Looking Statements section included in Part I of this Annual report. Our debt and associated commitments could have important adverse consequences. For example, these commitments could: • make it more difficult for us to satisfy our contractual obligations; • • • • • • increase our vulnerability to general adverse economic and industry conditions; limit our ability to fund future working capital, capital expenditures, investments, acquisitions or other corporate requirements; increase our vulnerability to interest rate fluctuations because the interest payments on borrowings under our revolving credit facility are based upon variable interest rates and can adjust based upon our credit statistics; limit our flexibility in planning for, or reacting to, changes in our business and our industry; place us at a disadvantage compared to our competitors that have less debt or less restrictive covenants in such debt; and limit our ability to borrow additional funds in the future. Covenants in our debt agreements may restrict our ability to operate our business. Our credit agreement, consisting of a $680.0 million revolving credit facility expiring in November 2020, contains various covenants with which we, Exterran Energy Solutions, L.P. (“EESLP”), our wholly owned subsidiary, and our respective restricted subsidiaries must comply, including, but not limited to, limitations on the incurrence of indebtedness, investments, liens on assets, repurchasing equity, making distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. Additionally, we are required to maintain certain financial covenant ratios. If we fail to remain in compliance with these restrictions and financial covenants, we would be in default under our credit agreement. In addition, if we experience a material adverse effect on our assets, liabilities, financial condition, business or operations that, taken as a whole, impact our ability to perform our obligations under our credit agreement, this could lead to a default. A default under one of our debt agreements might trigger cross-default provisions under our other debt agreement, which would accelerate our obligation to repay our indebtedness under those agreements. If the repayment obligations on any of our indebtedness were to be accelerated, we may not be able to repay the debt or refinance the debt on acceptable terms, and our financial position would be materially adversely affected. As of December 31, 2017, we were in compliance with all financial covenants under our credit agreement. As a result of a covenant restriction included in our credit agreement, $585.2 million of the $640.3 million of undrawn capacity under our revolving credit facility was available for additional borrowings as of December 31, 2017. We may increase our debt or raise additional capital in the future, which could affect our financial condition, may decrease our profitability or could dilute our shareholders. We may increase our debt or raise additional capital in the future, subject to restrictions in our debt agreements. If our cash flow from operations is less than we anticipate, or if our cash requirements are more than we expect, we may require more financing. However, debt or equity financing may not be available to us on terms acceptable to us, if at all. If we incur additional debt or raise equity through the issuance of preferred stock, the terms of the debt or preferred stock issued may give the holders rights, preferences and privileges senior to those of holders of our common stock, particularly in the event of liquidation. The terms of the debt may also impose additional and more stringent restrictions on our operations than we currently have. If we raise funds through the issuance of additional equity, our shareholders’ ownership in us would be diluted. If we are unable to raise additional capital when needed, it could affect our financial health, which could negatively affect our shareholders. Risks Related to the Spin-off As a result of the Spin-off, we and Archrock are subject to certain noncompetition restrictions, which may limit our ability to grow our business. In connection with the completion of the Spin-off, we entered into a separation and distribution agreement with Archrock that contains certain noncompetition provisions addressing restrictions on our ability to provide compression contract operations and aftermarket services in the U.S. and on Archrock’s ability to provide compression contract operations and aftermarket services outside of the U.S. and product sales to customers worldwide that expire on November 3, 2018, subject to certain exceptions. These restrictions limit our ability to attract new compression contract operations and aftermarket services customers in the U.S., which will limit our ability to grow our business. In addition, if we are unable to enforce the limitations on Archrock’s ability to provide certain contract operations, aftermarket services and product sales, we may lose prospective customers to Archrock, which could affect our financial condition, results of operations and cash flows to suffer. We provide Archrock and its affiliates with certain manufactured products and we depend on Archrock and its affiliates for a significant amount of our product sales revenues. Archrock and its affiliates are among our largest customers. During the year ended December 31, 2017, Archrock and its affiliates accounted for approximately 12% of our total revenue. Therefore, we are indirectly subject to the operational and business risks of Archrock and its affiliates. If Archrock and its affiliates are unable to satisfy its obligations or reduces its demand for any reason, our revenues would decline and our financial condition, results of operations and cash flows could be adversely affected. Further, we have no control over Archrock and its affiliates, and Archrock and its affiliates may elect to pursue a business strategy that does not favor us or our business. We are subject to continuing contingent tax liabilities of Archrock. Certain tax liabilities of Archrock may become our obligations. Under the Code and the related rules and regulations, each corporation that was a member of the Archrock consolidated U.S. federal income tax reporting group during any taxable period or portion of any taxable period ending on or before the effective time of the Spin-off is jointly and severally liable for the U.S. federal income tax liability of the entire Archrock consolidated tax reporting group for that taxable period. In connection with the Spin-off, we entered into a tax matters agreement with Archrock that allocates the responsibility for prior period taxes of the Archrock consolidated tax reporting group between us and Archrock. If Archrock is unable to pay any prior period taxes for which it is responsible, we could be required to pay the entire amount of such taxes. Our prior and continuing relationship with Archrock exposes us to risks attributable to businesses of Archrock. Archrock is obligated to indemnify us for losses that third parties may seek to impose upon us or our affiliates for liabilities relating to the business of Archrock that are incurred through a breach of the separation and distribution agreement or any ancillary agreement by Archrock or its affiliates other than us, or losses that are attributable to Archrock in connection with the Spin-off or are not expressly assumed by us under our agreements with Archrock. Any claims made against us that are properly attributable to Archrock in accordance with these arrangements would require us to exercise our rights under our agreements with Archrock to obtain payment from Archrock. We are exposed to the risk that, in these circumstances, Archrock cannot, or will not, make the required payment. In connection with our separation from Archrock, Archrock will indemnify us for certain liabilities, and we will indemnify Archrock for certain liabilities. If we are required to act on these indemnities to Archrock, we may need to divert cash to meet those obligations, and our financial results could be negatively impacted. In the case of Archrock’s indemnity, there can be no assurance that the indemnity will be sufficient to insure us against the full amount of such liabilities, or as to Archrock’s ability to satisfy its indemnification obligations. Pursuant to the separation and distribution agreement and other agreements with Archrock, Archrock has agreed to indemnify us for certain liabilities, and we have agreed to indemnify Archrock for certain liabilities, in each case for uncapped amounts, as discussed further in our Registration Statement. Under the separation and distribution agreement, we and Archrock will generally release the other party from all claims arising prior to the Spin-off that relate to the other party’s business, subject to certain exceptions. Also pursuant to the separation and distribution agreement, we have agreed to use our commercially reasonable efforts to remove Archrock as a party to certain of our contracts with third parties. In the event that Archrock remains as a party, we expect to indemnify Archrock for any liabilities relating to such contracts. Indemnities that we may be required to provide Archrock will not be subject to any cap, may be significant and could negatively impact our business, particularly indemnities relating to our actions that could impact the tax-free nature of the Spin-off. With respect to Archrock’s agreement to indemnify us, there can be no assurance that the indemnity from Archrock will be sufficient to protect us against the full amount of such liabilities, or that Archrock will be able to fully satisfy its indemnification obligations. Moreover, even if we ultimately succeed in recovering from Archrock any amounts for which we are held liable, we may be temporarily required to bear these losses ourselves. Each of these risks could negatively affect our business, cash flows, results of operations and financial condition. Risks Related to Our Common Stock The market price and trading volume of our common stock may be volatile. The market price of our stock may be influenced by many factors, some of which are beyond our control, including the following: • • • • • • • • • the inability to meet the financial estimates of analysts who follow our common stock; strategic actions by us or our competitors; announcements by us or our competitors of significant contracts, acquisitions, joint marketing relationships, joint ventures or capital commitments; variations in our quarterly operating results and those of our competitors; general economic and stock market conditions; risks relating to our business and our industry, including those discussed above; changes in conditions or trends in our industry, markets or customers; cyber-attacks or terrorist acts; future sales of our common stock or other securities; • material weaknesses in our internal control over financial reporting; and • investor perceptions of the investment opportunity associated with our common stock relative to other investment alternatives. These broad market and industry factors may materially reduce the market price of our common stock, regardless of our operating performance. In addition, price volatility may be greater if the public float and trading volume of our common stock is low. Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain types of actions and proceedings that may be initiated by our stockholders, which could limit our stockholders’ ability to choose the judicial forum for disputes with us or our directors, officers or other employees. Our amended and restated certificate of incorporation provides that, unless we consent in writing to the selection of an alternate forum, the sole and exclusive forum for (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee to us or our stockholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our bylaws, in each case, as amended from time to time, or (iv) any action asserting a claim governed by the internal affairs doctrine, shall be the Court of Chancery of the State of Delaware, in all cases subject to the court’s having personal jurisdiction over the indispensable parties named as defendants. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock is deemed to have received notice of and consented to the foregoing provision. This forum selection provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable or cost-effective for disputes with us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and employees. Item 1B. Unresolved Staff Comments None. Item 2. Properties The following table describes the material facilities we owned or leased as of December 31, 2017: Location Houston, Texas Camacari, Brazil Neuquen, Argentina Reynosa, Mexico Santa Cruz, Bolivia Bangkok, Thailand Port Harcourt, Nigeria Houston, Texas Hamriyah Free Zone, UAE Broken Arrow, Oklahoma Singapore, Singapore Item 3.

While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from any of these actions will not have a material adverse effect on our financial position, results of operations or cash flows. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our financial position, results of operations or cash flows. Contemporaneously with filing the Form 8-K on April 26, 2016, we self-reported the errors and possible irregularities at Belleli EPC to the SEC. Since then, we have been cooperating with the SEC in its investigation of this matter, which has included responding to a subpoena for documents related to the restatement and of our compliance with the FCPA, which were also provided to the Department of Justice at its request. The SEC staff has notified us that they have concluded their investigation concerning our compliance with the FCPA and that they do not intend to recommend an enforcement action concerning our compliance with the FCPA. The DOJ has similarly informed us that it does not intend to proceed with any further investigation or enforcement. The SEC’s investigation related to the circumstances giving rise to the restatement is continuing, and we are presently unable to predict the duration, scope or results or whether the SEC will commence any legal action. Item 4. Mine Safety Disclosures Not applicable. PART II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Our common stock is listed and traded on the New York Stock Exchange under the stock symbol “EXTN.” The following table sets forth the range of high and low sale prices for our common stock for the period indicated. First Quarter Second Quarter Third Quarter Fourth Quarter Years Ended December 31, 2017 2016 High Low High Low $ $ $ $ 34.05 31.93 32.78 33.69 $ $ $ $ 24.13 24.83 23.29 28.34 $ $ $ $ 16.99 17.13 15.90 24.84 $ $ $ $ 12.07 10.83 11.87 14.51 On February 20, 2018, the closing price of our common stock was $27.07 per share. As of February 20, 2018, there were approximately 1,012 holders of record of our common stock. We have not paid, and we do not currently anticipate paying cash dividends on our common stock. Instead, we intend to retain our future earnings to support the growth and development of our business. The declaration of any future cash dividends and, if declared, the amount of any such dividends, will be subject to our financial condition, earnings, capital requirements, financial covenants, applicable law and other factors our board of directors deems relevant. Therefore, there can be no assurance as to what level of dividends, if any, will be paid in the future. For disclosures regarding securities authorized for issuance under our equity compensation plans, see Part III, Item 12 (“Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters”) of this report. Comparison of Cumulative Total Return The performance graph below shows the cumulative total stockholder return on our common stock, compared with the S&P 500 Composite Stock Price Index (the “S&P 500 Index”) and the Oilfield Service Index (the “OSX Index”) over the period from November 4, 2015, the first day of trading volume, to December 31, 2017. The results are based on an investment of $100 in each of our common stock, the S&P 500 Index and the OSX Index. The graph assumes the reinvestment of dividends and adjusts all closing prices and dividends for stock splits. The performance graph shall not be deemed incorporated by reference by any general statement incorporating by reference this Annual Report on Form 10-K into any filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except to the extent that we specifically incorporate this information by reference, and shall not otherwise be deemed filed under those Acts. Unregistered Sales of Equity Securities and Use of Proceeds None. Repurchase of Equity Securities The following table summarizes our repurchases of equity securities during the three months ended December 31, 2017: Period October 1, 2017 - October 31, 2017 November 1, 2017 - November 30, 2017 December 1, 2017 - December 31, 2017 Total Total Number of Shares Repurchased (1) Average Price Paid Per Unit Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs Maximum Number of Shares yet to be Purchased Under the Publicly Announced Plans or Programs — $ — 45,559 1,155 31.58 29.34 46,714 $ 31.52 N/A N/A N/A N/A N/A N/A N/A N/A (1) Represents shares withheld to satisfy employees’ tax withholding obligations in connection with vesting of restricted stock awards during the period.  Item 6. Selected Financial Data The table below presents certain selected historical consolidated and combined financial information as of and for each of the years in the five-year period ended December 31, 2017. The selected historical consolidated financial data as of December 31, 2017 and 2016 and the selected historical consolidated and combined financial data for the years ended December 31, 2017, 2016 and 2015 has been derived from our audited Financial Statements included elsewhere in this report. The selected historical consolidated and combined financial data as of December 31, 2015, 2014 and 2013 and for the years ended December 31, 2014 and 2013 has been derived from our financial statements not included in this report. Our Spin-off from Archrock was completed on November 3, 2015. Selected financial data for periods prior to the Spin-off represent the combined results of Archrock’s international services and product sales businesses. The combined financial data may not be indicative of our future performance and does not necessarily reflect the financial condition and results of operations we would have realized had we operated as a separate, stand-alone entity during the periods presented, including changes in our operations as a result of our Spin-off from Archrock. As discussed in Note 3 to our Financial Statements, the results from continuing operations for all periods presented exclude the results of our Venezuelan contract operations business, Canadian contract operations and aftermarket services businesses (“Canadian Operations”), Belleli CPE business (the manufacture of critical process equipment for refinery and petrochemical facilities) and Belleli EPC business (the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants). Those results are reflected in discontinued operations for all periods presented. The selected financial data presented below should be read together with Management’s Discussion and Analysis of Financial Condition and Results of Operations and the Financial Statements contained in this report. (in thousands, except per share data) 2017 2016 2015 2014 2013 Years Ended December 31, Statement of Operations Data: Revenues $ 1,215,294 $ 905,397 $ 1,687,264 $ 1,986,184 $ 2,247,778 Cost of sales (excluding depreciation and amortization expense) Selling, general and administrative Depreciation and amortization Long-lived asset impairment Restatement related charges Restructuring and other charges Interest expense Equity in income of non-consolidated affiliates Other (income) expense, net Income (loss) before income taxes Provision for income taxes Income (loss) from continuing operations Income (loss) from discontinued operations, net of tax Net income (loss) Income (loss) from continuing operations per common share: (1) 868,154 176,318 107,824 5,700 3,419 3,189 34,826 — (975) 16,839 22,695 (5,856) 39,736 33,880 596,406 157,485 132,886 14,495 18,879 22,038 34,181 (10,403) (13,046) (47,524) 124,242 (171,766) (56,171) (227,937) 1,189,361 1,395,007 1,676,661 210,483 146,318 20,788 — 31,315 7,272 (15,152) 35,516 61,363 39,438 21,925 4,723 26,648 252,130 163,538 3,851 — — 1,878 (14,553) 5,572 178,761 79,210 99,551 15,741 115,292 248,336 131,904 11,941 — — 3,523 (19,000) (2,855) 197,268 89,557 107,711 16,006 123,717 Basic Diluted $ (0.17) $ (0.17) (4.97) $ (4.97) $ 0.64 0.64 $ 2.90 2.90 3.14 3.14 Weighted average common shares outstanding used in income (loss) from continuing operations per common share: (1) Basic Diluted Other Financial Data: Total gross margin (2) EBITDA, as adjusted (2) Capital expenditures: Contract Operations Equipment: Growth (3) Maintenance (4) Other Balance Sheet Data: Cash and cash equivalents Working capital (5) (6) Property, plant and equipment, net Total assets (6) Long-term debt (7) Total stockholders’ equity (6) (7) 34,959 34,959 34,568 34,568 34,288 34,304 34,286 34,286 34,286 34,286 $ 347,140 $ 308,991 $ 497,903 $ 591,177 $ 571,117 173,155 155,993 282,031 338,050 329,949 $ $ 104,909 15,691 11,073 $ 53,005 14,440 6,225 $ 105,169 27,282 22,893 $ 97,931 24,377 24,164 36,468 21,591 31,992 $ 49,145 $ 35,678 $ 29,032 $ 39,361 $ 35,194 134,048 822,279 177,824 790,922 408,488 846,977 366,135 890,627 305,848 897,396 1,460,807 1,374,778 1,788,396 1,999,303 1,973,622 368,472 554,786 348,970 556,771 525,593 805,936 1,107 1,539 1,364,335 1,321,160 (1) For the periods prior to November 3, 2015, the average number of common shares outstanding used to calculate basic and diluted net income (loss) from continuing operations per common share was based on 34,286,267 shares of our common stock that were distributed by Archrock in the Spin-off on November 3, 2015. (2) Total gross margin and EBITDA, as adjusted, are non-GAAP financial measures. Total gross margin and EBITDA, as adjusted, are defined, reconciled to income (loss) before income taxes and net income (loss), respectively, and discussed further below under “Non-GAAP Financial Measures.” (3) Growth capital expenditures are made to expand or to replace partially or fully depreciated assets or to expand the operating capacity or revenue generating capabilities of existing or new assets, whether through construction, acquisition or modification. The majority of our growth capital expenditures are related to the acquisition cost of new compressor units and processing and treating equipment that we add to our contract operations fleet and installation costs on integrated projects. In addition, growth capital expenditures can include the upgrading of major components on an existing compressor unit where the current configuration of the compressor unit is no longer in demand and the compressor unit is not likely to return to an operating status without the capital expenditures. These latter expenditures substantially modify the operating parameters of the compressor unit such that it can be used in applications for which it previously was not suited. (4) Maintenance capital expenditures are made to maintain the existing operating capacity of our assets and related cash flows further extending the useful lives of the assets. Maintenance capital expenditures are related to major overhauls of significant components of a compressor unit, such as the engine, compressor and cooler, that return the components to a “like new” condition, but do not modify the applications for which the compressor unit was designed. (5) Working capital is defined as current assets minus current liabilities. (6) Amounts include balance sheet data for discontinued operations. (7) Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, we transferred $532.6 million of net proceeds from borrowings under our credit facility to Archrock to allow it to repay a portion of its indebtedness in connection with the Spin-off. Non-GAAP Financial Measures We define gross margin as total revenue less cost of sales (excluding depreciation and amortization expense). We evaluate the performance of each of our segments based on gross margin. Total gross margin is included as a supplemental disclosure because it is a primary measure used by our management to evaluate the results of revenue and cost of sales (excluding depreciation and amortization expense), which are key components of our operations. We believe gross margin is important because it focuses on the current operating performance of our operations and excludes the impact of the prior historical costs of the assets acquired or constructed that are utilized in those operations, the indirect costs associated with our selling, general and administrative (“SG&A”) activities, the impact of our financing methods and income taxes. Depreciation and amortization expense may not accurately reflect the costs required to maintain and replenish the operational usage of our assets and therefore may not portray the costs from current operating activity. As an indicator of our operating performance, total gross margin should not be considered an alternative to, or more meaningful than, income (loss) before income taxes as determined in accordance with generally accepted accounting principles in the U.S. (“GAAP”). Our gross margin may not be comparable to a similarly titled measure of another company because other entities may not calculate gross margin in the same manner. Total gross margin has certain material limitations associated with its use as compared to income (loss) before income taxes. These limitations are primarily due to the exclusion of interest expense, depreciation and amortization expense, SG&A expense, impairments and restructuring and other charges. Each of these excluded expenses is material to our statements of operations. Because we intend to finance a portion of our operations through borrowings, interest expense is a necessary element of our costs and our ability to generate revenue. Additionally, because we use capital assets, depreciation expense is a necessary element of our costs and our ability to generate revenue, and SG&A expenses are necessary to support our operations and required corporate activities. To compensate for these limitations, management uses total gross margin, a non-GAAP measure, as a supplemental measure to other GAAP results to provide a more complete understanding of our performance. The following table reconciles our net income (loss) before income taxes to total gross margin (in thousands): Years Ended December 31, Income (loss) before income taxes Selling, general and administrative Depreciation and amortization Long-lived asset impairment Restatement related charges Restructuring and other charges Interest expense Equity in income of non-consolidated affiliates Other (income) expense, net Total gross margin 2017 $ 16,839 $ 176,318 107,824 5,700 3,419 3,189 34,826 — (975) 347,140 $ $ 2016 (47,524) $ 157,485 132,886 14,495 18,879 22,038 34,181 (10,403) (13,046) 308,991 2015 2014 2013 61,363 $ 178,761 $ 197,268 210,483 146,318 20,788 — 31,315 7,272 (15,152) 35,516 252,130 163,538 3,851 — — 1,878 (14,553) 5,572 $ 497,903 $ 591,177 $ 248,336 131,904 11,941 — — 3,523 (19,000) (2,855) 571,117 We define EBITDA, as adjusted, as net income (loss) excluding income (loss) from discontinued operations (net of tax), cumulative effect of accounting changes (net of tax), income taxes, interest expense (including debt extinguishment costs), depreciation and amortization expense, impairment charges, restructuring and other charges, non-cash gains or losses from foreign currency exchange rate changes recorded on intercompany obligations, expensed acquisition costs and other items. We believe EBITDA, as adjusted, is an important measure of operating performance because it allows management, investors and others to evaluate and compare our core operating results from period to period by removing the impact of our capital structure (interest expense from our outstanding debt), asset base (depreciation and amortization), our subsidiaries’ capital structure (non-cash gains or losses from foreign currency exchange rate changes on intercompany obligations), tax consequences, impairment charges, restructuring and other charges, expensed acquisition costs and other items. Management uses EBITDA, as adjusted, as a supplemental measure to review current period operating performance, comparability measures and performance measures for period to period comparisons. In addition, the compensation committee has used EBITDA, as adjusted, in evaluating the performance of the Company and management and in evaluating certain components of executive compensation, including performance-based annual incentive programs. Our EBITDA, as adjusted, may not be comparable to a similarly titled measure of another company because other entities may not calculate EBITDA in the same manner. EBITDA, as adjusted, is not a measure of financial performance under GAAP and should not be considered in isolation or as an alternative to net income (loss), cash flows from operating activities or any other measure determined in accordance with GAAP. Items excluded from EBITDA, as adjusted, are significant and necessary components to the operation of our business and therefore, EBITDA, as adjusted, should only be used as a supplemental measure of our operating performance. The following table reconciles our net income (loss) to EBITDA, as adjusted (in thousands): Net income (loss) (Income) loss from discontinued operations, net of tax Depreciation and amortization Long-lived asset impairment Restatement related charges Restructuring and other charges Investment in non-consolidated affiliates impairment Proceeds from sale of joint venture assets Interest expense (Gain) loss on currency exchange rate remeasurement of intercompany balances Loss on sale of businesses Penalties from Brazilian tax programs Provision for income taxes EBITDA, as adjusted Off-Balance Sheet Arrangements We have no material off-balance sheet arrangements.

Management’s Discussion and Analysis of Financial Condition and Results of Operations The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our Financial Statements, the notes thereto, and the other financial information appearing elsewhere in this report. The following discussion includes forward-looking statements that involve certain risks and uncertainties. See Part I (“Disclosure Regarding Forward-Looking Statements”) and Part I, Item 1A (“Risk Factors”) in this report. Overview We are a global systems and process company offering solutions in the oil, gas, water and power markets. We are a market leader in natural gas processing and treatment and compression products and services, providing critical midstream infrastructure solutions to customers throughout the world. Outside the U.S., we are a leading provider of full-service natural gas contract compression, and a supplier of aftermarket parts and services. We provide our products and services to a global customer base consisting of companies engaged in all aspects of the oil and natural gas industry, including large integrated oil and natural gas companies, national oil and natural gas companies, independent oil and natural gas producers and oil and natural gas processors, gatherers and pipeline operators. We operate in three primary business lines: contract operations, aftermarket services and product sales. In our contract operations business line, we own and operate natural gas compression equipment and crude oil and natural gas production and processing equipment on behalf of our customers outside of the U.S. In our aftermarket services business line, we sell parts and components and provide operations, maintenance, overhaul, upgrade, commissioning and reconfiguration services to customers outside of the U.S. who own their own compression, production, processing, treating and related equipment. In our product sales business line, we design, engineer, manufacture, install and sell natural gas compression packages as well as equipment used in the production, treating and processing of crude oil and natural gas to our customers throughout the world and for use in our contract operations business line. We also offer our customers, on either a contract operations basis or a sale basis, the engineering, design, project management, procurement and construction services necessary to incorporate our products into production, processing and compression facilities, which we refer to as integrated projects. Spin-off On November 3, 2015, Archrock, Inc. (named Exterran Holdings, Inc. prior to November 3, 2015) (“Archrock”) completed the spin-off (the “Spin-off”) of its international contract operations, international aftermarket services (the international contract operations and international aftermarket services businesses combined are referred to as the “international services businesses” and include such activities conducted outside of the U.S.) and global fabrication businesses into an independent, publicly traded company (“Exterran Corporation,” “our,” “we” or “us”). To effect the Spin-off, on November 3, 2015, Archrock distributed, on a pro rata basis, all of our shares of common stock to its stockholders of record as of October 27, 2015 (the “Record Date”). Archrock shareholders received one share of Exterran Corporation common stock for every two shares of Archrock common stock held at the close of business on the Record Date. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, we transferred cash of $532.6 million to Archrock. Following the completion of the Spin-off, we and Archrock became and continue to be independent, publicly traded companies with separate boards of directors and management. Basis of Presentation The accompanying Financial Statements in Part IV, Item 15, have been prepared in accordance with GAAP. All financial information presented for periods after the Spin-off represents our consolidated results of operations, financial position and cash flows (referred to as the “consolidated financial statements”) and all financial information for periods prior to the Spin-off represents our combined results of operations, financial position and cash flows (referred to as the “combined financial statements”). Accordingly: • Our consolidated and combined statements of operations, comprehensive income, cash flows and stockholders’ equity for the year ended December 31, 2015 consist of (i) the combined results of Archrock’s international services and product sales businesses for the period between January 1, 2015 and November 3, 2015 and (ii) the consolidated results of Exterran Corporation for periods subsequent to November 3, 2015. • Our consolidated balance sheets at December 31, 2017 and 2016 consist entirely of our consolidated balances. The combined financial statements were derived from the accounting records of Archrock and reflect the combined historical results of operations, financial position and cash flows of Archrock’s international services and product sales businesses. The combined financial statements were presented as if such businesses had been combined for periods prior to November 4, 2015. All intercompany transactions and accounts within these statements have been eliminated. Affiliate transactions between the international services and product sales businesses of Archrock and the other businesses of Archrock have been included in the combined financial statements, with the exception of product sales within our wholly owned subsidiary, EESLP. Prior to the closing of the Spin-off, EESLP also had a fleet of compression units used to provide compression services in the U.S. services business of Archrock. Revenue has not been recognized in the combined statements of operations for the sale of compressor units by us that were used by EESLP to provide compression services to customers of the U.S. services business of Archrock. See Note 17 to the Financial Statements for further discussion on transactions with affiliates. The combined statements of operations for periods prior to the Spin-off include expense allocations for certain functions historically performed by Archrock and not allocated to its operating segments, including allocations of expenses related to executive oversight, accounting, treasury, tax, legal, human resources, procurement and information technology. See Note 17 to the Financial Statements for further discussion regarding the allocation of corporate expenses. Additionally, third party debt of Archrock, other than debt attributable to capital leases, was not allocated to us for any of the periods prior to the Spin-off as we were not the legal obligor of the debt and Archrock’s borrowings were not directly attributable to our business. We refer to the consolidated and combined financial statements collectively as “financial statements,” and individually as “balance sheets,” “statements of operations,” “statements of comprehensive income (loss),” “statements of stockholders’ equity” and “statements of cash flows” herein. Industry Conditions and Trends Our business environment and corresponding operating results are affected by the level of energy industry spending for the exploration, development and production of oil and natural gas reserves. Spending by oil and natural gas exploration and production companies is dependent upon these companies’ forecasts regarding the expected future supply, demand and pricing of oil and natural gas products as well as their estimates of risk-adjusted costs to find, develop and produce reserves. Although we believe our contract operations business, and to a lesser extent our product sales business, is typically less impacted by short-term commodity prices than certain other energy products and service providers, changes in oil and natural gas exploration and production spending normally result in changes in demand for our products and services. After a period of significant declines in commodity prices, which resulted in reduced investment on the part of our customers, commodity prices started to increase which led to increased customer spending in 2017, primarily in North America. As such, we experienced higher activity levels in North America, which resulted in higher demand for gas processing and treating plants and compression equipment within our product sales business. Oil prices rose largely due to OPEC’s agreement to limit production, which incentivized U.S. producers to increase their investments in shale oil. International activity was not meaningfully impacted by higher commodity prices primarily due to uncertainty regarding oil and natural gas supply and demand fundamentals as well as concerns over the effectiveness of the OPEC-led production cuts. Industry observers anticipate that commodity prices and customer spending should continue to increase in 2018 due to the predicted strong global demand for hydrocarbons, including increased demand for liquefied natural gas. Geographically, North America is expected to see the largest increase in industry spending with international markets anticipated to grow for the first time in four years, albeit at modest levels. However, customer cash flows and returns on capital could drive customer investment priorities. Industry observers believe shareholders are encouraging management teams of energy producers to focus operational and compensation strategies on returns and cash flow generation rather than solely on production growth. To accomplish these strategies, industry observers believe that energy producers would need to better prioritize capital spending such that cash required for their investments would not exceed cash generated from their operating cash flows. This could impact resource allocation and ultimately the amount of new projects and capital spending by our customers. Our Performance Trends and Outlook Our revenue, earnings and financial position are affected by, among other things, market conditions that impact demand and pricing for natural gas compression and oil and natural gas production and processing and our customers’ decisions to use our products and services, use our competitors’ products and services or own and operate the equipment themselves. Low commodity prices in 2015 and the first half of 2016 led to reduced energy related capital spending in those years by our customers in North America. Customer spending and investments in equipment increased in 2017 as commodity prices, primarily oil prices, rebounded from their cyclical lows, leading to a sharp increase in bookings during the year. The Henry Hub spot price for natural gas was $3.69 per MMBtu at December 31, 2017, which was 1% lower and 62% higher than prices at December 2016 and 2015, respectively, and the U.S. natural gas liquid composite price was $8.03 per MMBtu for the month of November 2017, which was 21% and 90% higher than prices for the months of December 2016 and 2015, respectively. In addition, the West Texas Intermediate crude oil spot price as of December 31, 2017 was 12% and 63% higher than prices at December 31, 2016 and 2015, respectively. During periods of lower oil or natural gas prices, our customers typically decrease their capital expenditures, which generally results in lower activity levels. Third party booking activity levels for our manufactured products in North America during the year ended December 31, 2017 were $829.8 million, which represents an increase of 141% and 112% compared to the years ended December 31, 2016 and 2015, respectively, and our North America product sales backlog as of December 31, 2017 was $421.3 million, which represents an increase of 77% and 88% compared to December 31, 2016 and 2015, respectively. We believe recent booking levels reflect the expectation that commodity prices will continue to remain above the low levels experienced in early 2016 as well as the selective deployment of capital by our customers in certain North America basins. We expect that industry spending in international markets will begin to recover in 2018. Longer-term fundamentals in our international markets partially depends on international oil and gas infrastructure projects, many of which are based on longer- term plans of our customers that can be driven by their local market demand and local pricing for natural gas. As a result, we believe our international customers make decisions based on longer-term fundamentals that may be less tied to near term commodity prices than our North American customers. However, lower oil and natural gas prices in international markets have had some negative impacts on the amount of capital investment in new projects by our customers in recent years. Over the long term, we believe the demand for our products and services in international markets will continue, and we expect to have opportunities to grow our international businesses. Third party booking activity levels for our manufactured products in international markets during the year ended December 31, 2017 were $58.0 million, which represents a decrease of 34% and an increase of 24% compared to the year ended December 31, 2016 and 2015, respectively, and our international product sales backlog as of December 31, 2017 was $39.7 million, which represents a decrease of 42% and 9% compared to December 31, 2016 and 2015, respectively. Aggregate third party booking activity levels for our manufactured products in North America and international markets during the year ended December 31, 2017 were $887.8 million, which represents an increase of 106% and 103% compared to the years ended December 31, 2016 and 2015, respectively. The aggregate product sales backlog for our manufactured products in North America and international markets as of December 31, 2017 was $461.0 million, which represents an increase of 51% and 72% compared to December 31, 2016 and 2015, respectively. Fluctuations in the size and timing of customer requests for bid proposals and awards of new contracts tend to create variability in booking activity levels from period to period. The timing of any change in activity levels by our customers is difficult to predict. As a result, our ability to project the anticipated activity level for our business, and particularly our product sales segment, is limited. In the latter part of 2016 and throughout 2017, we experienced an increase in product sales bookings. However, volatility in commodity prices could delay investments by our customers in significant projects, which could result in a material adverse effect on our business, financial condition, results of operations and cash flows. Our level of capital spending depends on our forecast for the demand for our products and services and the equipment required to provide services to our customers. Based on the demand we see for contract operations, we anticipate investing more capital in our contract operations business in 2018 than we did in 2017. The increased investment during 2018 is driven by several large multi-year projects contracted in 2017, or that are expected to be contracted in 2018, that are scheduled or anticipated to start earning revenue in 2018 and 2019. Certain Key Challenges and Uncertainties Market conditions and competition in the oil and natural gas industry and the risks inherent in international markets continue to represent key challenges and uncertainties. In addition to these challenges, we believe the following represent some of the key challenges and uncertainties we will face in the future: Global Energy Markets and Oil and Natural Gas Pricing. Our results of operations depend upon the level of activity in the global energy markets, including oil and natural gas development, production, processing and transportation. Oil and natural gas prices and the level of drilling and exploration activity can be volatile. If oil and natural gas exploration and development activity and the number of well completions decline due to the reduction in oil and natural gas prices or significant instability in energy markets, we would anticipate a decrease in demand and pricing for our natural gas compression and oil and natural gas production and processing equipment and services. For example, unfavorable market conditions or financial difficulties experienced by our customers may result in cancellation of contracts or the delay or abandonment of projects, which could cause our cash flows generated by our product sales and international services to decline and have a material adverse effect on our results of operations and financial condition. Execution on Larger Contract Operations and Product Sales Projects. Some of our projects are significant in size and scope, which can translate into more technically challenging conditions or performance specifications for our products and services. Contracts with our customers generally specify delivery dates, performance criteria and penalties for our failure to perform. Any failure to execute such larger projects in a timely and cost effective manner could have a material adverse effect on our business, financial condition, results of operations and cash flows. Personnel, Hiring, Training and Retention. We believe our ability to grow may be challenged by our ability to hire, train and retain qualified personnel. Although we have been able to satisfy our personnel needs thus far, retaining employees in our industry continues to be a challenge. Our ability to continue our growth will depend in part on our success in hiring, training and retaining these employees. Summary of Results As discussed in Note 3 to the Financial Statements, the results from continuing operations for all periods presented exclude the results of our Venezuelan contract operations, Belleli CPE and Belleli EPC businesses. Those results are reflected in discontinued operations for all periods presented. Revenue. Revenue during the years ended December 31, 2017, 2016 and 2015 was $1,215.3 million, $905.4 million and $1,687.3 million, respectively. The increase in revenue during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to a significant increase in revenue in our product sales segment, partially offset by decreases in revenue in our contract operations and aftermarket services segments. The decrease in revenue during the year ended December 31, 2016 compared to the year ended December 31, 2015 was caused by revenue decreases in our product sales and contract operations segments. Net income (loss). We generated net income of $33.9 million during the year ended December 31, 2017, net loss of $227.9 million during the year ended December 31, 2016 and net income of $26.6 million during the year ended December 31, 2015. The increase in net income during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to non-cash valuation allowances of $119.8 million recorded against U.S. net deferred tax assets during 2016, an increase in income from discontinued operations, net of tax, an increase in gross margin for our product sales segment, a decrease in depreciation and amortization expense and a decrease in restructuring and other charges. These activities were partially offset by an increase in SG&A expense. Net income (loss) during the years ended December 31, 2017 and 2016 included income from discontinued operations, net of tax, of $39.7 million and loss from discontinued operations, net of tax, of $56.2 million, respectively. Income from discontinued operations, net of tax, for 2017 was positively impacted by recoveries from liquidated damages releases and customer approved change orders related to Belleli EPC. Loss from discontinued operations, net of tax, for 2016 included impairment charges of $68.8 million related to Belleli CPE. The decrease in net income during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to a decrease in gross margin in our product sales and contract operations segments, non-cash valuation allowances of $119.8 million recorded against U.S. deferred tax assets during 2016 and impairment charges reflected in loss from discontinued operations, net of tax, of $68.8 million related to Belleli CPE during 2016. These activities were partially offset by a decrease in SG&A expense and foreign currency gains of $6.5 million during 2016 compared to foreign currency losses of $35.8 million during 2015. Net loss during the year ended December 31, 2016 included loss from discontinued operations, net of tax, of $56.2 million and net income during the year ended December 31, 2015 included income from discontinued operations, net of tax, of $4.7 million. EBITDA, as adjusted. Our EBITDA, as adjusted, was $173.2 million, $156.0 million and $282.0 million during the years ended December 31, 2017, 2016 and 2015, respectively. EBITDA, as adjusted, during the year ended December 31, 2017 compared to the year ended December 31, 2016 increased primarily due to an increase in gross margin for our product sales segment, partially offset by an increase in SG&A expense and decreases in gross margin for our aftermarket services and contract operations segments. EBITDA, as adjusted, during the year ended December 31, 2016 compared to the year ended December 31, 2015 decreased primarily due to decreases in gross margin in our product sales and contract operations segments, partially offset by a decrease in SG&A expense. For a reconciliation of EBITDA, as adjusted, to net income (loss), its most directly comparable financial measure calculated and presented in accordance with GAAP, please read Part II, Item 6 (“Selected Financial Data — Non-GAAP Financial Measures”) of this report. Results by Business Segment. The following table summarizes revenue, gross margin and gross margin percentages for each of our business segments (dollars in thousands): Revenue: Contract Operations Aftermarket Services Product Sales Gross Margin: (1) Contract Operations Aftermarket Services Product Sales Gross Margin Percentage: (2) Contract Operations Aftermarket Services Product Sales Years Ended December 31, 2017 2016 2015 $ 375,269 $ 392,463 $ 469,900 107,063 732,962 $ 1,215,294 $ 241,889 28,842 76,409 $ $ 120,550 392,384 905,397 127,802 1,089,562 $ 1,687,264 248,793 $ 297,509 33,208 26,990 36,569 163,825 $ 347,140 $ 308,991 $ 497,903 64% 27% 10% 63% 28% 7% 63% 29% 15% (1) (2) Gross margin is defined as revenue less cost of sales (excluding depreciation and amortization expense). We evaluate the performance of each of our segments based on gross margin. Gross margin percentage is defined as gross margin divided by revenue. Operating Highlights The following table summarizes our product sales backlog (in thousands): Product Sales Backlog: (1) Compressor and Accessory Backlog Production and Processing Equipment Backlog Installation Backlog Total December 31, 2017 2016 2015 $ $ 254,745 $ 160,006 $ 206,229 72 144,252 1,964 141,059 118,914 7,445 461,046 $ 306,222 $ 267,418 (1) Our product sales backlog consists of unfilled orders based on signed contracts and does not include potential product sales pursuant to letters of intent received from customers. We expect that our product sales backlog will be recognized before December 31, 2018. Results of Operations The Year Ended December 31, 2017 Compared to the Year Ended December 31, 2016 Contract Operations (dollars in thousands) Revenue Cost of sales (excluding depreciation and amortization expense) Gross margin Gross margin percentage Years Ended December 31, 2017 375,269 133,380 241,889 $ $ 2016 392,463 143,670 248,793 $ $ 64% 63% Increase (Decrease) (4)% (7)% (3)% 1 % The decrease in revenue during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to a $15.4 million decrease in revenue in Mexico primarily driven by projects that terminated operations in 2016 and a decrease in revenue of $7.7 million resulting from an early termination of a project in Indonesia in January 2016 that had been operating since the third quarter of 2009. These decreases were partially offset by an $8.0 million increase in revenue in Brazil primarily driven by the start-up of a project during the second half of 2016. Gross margin decreased during the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily due to the revenue decrease explained above, partially offset by demobilization expenses of $6.1 million incurred in the prior year period on the early termination of a project in Indonesia discussed above. Gross margin percentage during the year ended December 31, 2017 compared to the year ended December 31, 2016 remained relatively flat. Aftermarket Services (dollars in thousands) Revenue Cost of sales (excluding depreciation and amortization expense) Gross margin Gross margin percentage Years Ended December 31, 2017 107,063 78,221 28,842 $ $ 2016 120,550 87,342 33,208 $ $ 27% 28% Increase (Decrease) (11)% (10)% (13)% (1)% The decrease in revenue during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to a decrease in operations and maintenance services of $5.2 million in Colombia, a decrease in parts sales of $7.1 million in China, a $3.3 million decrease in revenue due to the sale of our North America refurbishment and services business in the first quarter of 2017 and a $3.5 million decrease in revenue on a contract in the Middle East resulting from ongoing customer negotiations. These decreases were partially offset by a $4.6 million increase in Brazil primarily driven by increased maintenance services. Gross margin decreased during the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily due to the revenue decrease explained above. Gross margin percentage during the year ended December 31, 2017 compared to the year ended December 31, 2016 remained relatively flat. Product Sales (dollars in thousands) Revenue Cost of sales (excluding depreciation and amortization expense) Gross margin Gross margin percentage Years Ended December 31, 2017 732,962 656,553 76,409 $ $ 2016 392,384 365,394 26,990 $ $ 10% 7% Increase (Decrease) 87% 80% 183% 3% The increase in revenue during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to increases of $316.3 million and $32.4 million in North America and in the Middle East and Africa region, respectively, partially offset by a decrease of $16.7 million in the Asia Pacific region. The increase in revenue in North America was primarily due to a significant increase in North America booking activities during 2017 compared to 2016. In North America, compression equipment revenue and processing and treating equipment revenue increased by $168.6 million and $160.6 million, respectively, partially offset by a decrease of $10.3 million in production equipment revenue. The increase revenue in the Middle East and Africa region was primarily due to an increase of $29.6 million in processing and treating equipment revenue. The decrease in revenue in the Asia Pacific region was primarily due to a decrease of $15.1 million in compression equipment revenue. Gross margin and gross margin percentage increased during the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily due to the revenue increase explained above and a shift in product mix during the current year period. Costs and Expenses (dollars in thousands) Selling, general and administrative Depreciation and amortization Long-lived asset impairment Restatement related charges Restructuring and other charges Interest expense Equity in income of non-consolidated affiliates Other (income) expense, net Years Ended December 31, 2017 2016 Increase (Decrease) $ 176,318 $ 107,824 5,700 3,419 3,189 34,826 — (975) 157,485 132,886 14,495 18,879 22,038 34,181 (10,403) (13,046) 12 % (19)% (61)% (82)% (86)% 2 % (100)% (93)% Selling, general and administrative SG&A expense increased during the year ended December 31, 2017 compared to the year ended December 31, 2016 primarily due to the reinstitution of certain incentive compensation that was suspended in 2016 and an increase in third-party professional expenses primarily related to the redesign of our internal controls framework in an effort to remediate previously identified internal control deficiencies, partially offset by cost savings resulting from the portions of our cost reduction plan previously implemented. During the years ended December 31, 2017 and 2016, SG&A expense as a percentage of revenue was 15% and 17%, respectively. The facility previously utilized to manufacture products for our Belleli EPC business has been repurposed to manufacture product sales equipment. As such, certain personnel, buildings, equipment and other assets that were previously related to the Belleli EPC business will remain as part of our continuing operations. As a result, SG&A expense during the years ended December 31, 2017 and 2016 included $2.4 million and $2.3 million, respectively, of costs associated with our ongoing operations at our repurposed facility. Depreciation and amortization Depreciation and amortization expense during the year ended December 31, 2017 compared to the year ended December 31, 2016 decreased primarily due to depreciation expense of $22.2 million recognized during the year ended December 31, 2016 on a contract operations project in Indonesia that early terminated operations in January 2016. The depreciation expense recognized on this project in the prior year period primarily related to capitalized installation costs, which included, among other things, civil engineering, piping, electrical instrumentation and project management costs. The project had been operating since the third quarter of 2009. Long-lived asset impairment We regularly review the future deployment of our idle compression assets used in our contract operations segment for units that are not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. During the years ended December 31, 2017 and 2016, we determined that one idle compressor unit and 62 idle compressor units, respectively, would be retired from the active fleet. The retirement of these units from the active fleet triggered a review of these assets for impairment, and as a result, we recorded asset impairments of $0.6 million and $12.7 million, respectively, to reduce the book value of each unit to its estimated fair value. In the fourth quarter of 2017, we classified certain assets within our product sales business that we expect to sell within the next twelve months as assets held for sale. We also determined that certain other assets within our product sales business were assessed to have no future benefit to our ongoing operations. In conjunction with the planned disposition and assessment of certain other assets, we recorded an impairment of long-lived assets that totaled $5.1 million to write-down these assets to their approximate fair values. During the year ended December 31, 2016, we evaluated other assets for impairment and recorded long-lived asset impairments of $1.7 million on these assets. Restatement related charges As discussed in Note 14 to the Financial Statements, during the first quarter of 2016, our senior management identified errors relating to the application of percentage-of-completion accounting principles to specific Belleli EPC product sales projects. During the years ended December 31, 2017 and 2016, we incurred $6.2 million and $30.1 million, respectively, of external costs associated with an ongoing SEC investigation and remediation activities related to the restatement of our financial statements, of which $2.8 million and $11.2 million, respectively, was recovered from Archrock pursuant to the separation and distribution agreement. Restructuring and other charges In the second quarter of 2015, we announced a cost reduction plan primarily focused on workforce reductions and the reorganization of certain facilities. These actions were in response to unfavorable market conditions in North America combined with the impact of lower international activity due to customer budget cuts driven by lower oil prices. As a result of this plan, during the year ended December 31, 2017, we incurred restructuring and other charges of $2.6 million primarily related to employee termination benefits. During the year ended December 31, 2016, we incurred $18.1 million of restructuring and other charges as a result of this plan, which primarily related to $14.5 million of employee termination benefits and a $2.9 million charge for the exit of a corporate building under an operating lease. Additionally, during the year ended December 31, 2017, we incurred $0.6 million of costs associated with the Spin-off primarily related to retention awards to certain employees. During the year ended December 31, 2016, we incurred $3.9 million of costs associated with the Spin-off, of which $3.1 million related to retention awards to certain employees. The charges incurred in conjunction with the cost reduction plan and Spin-off are included in restructuring and other charges in our statements of operations. We have substantially completed restructuring activities related to the Spin-off and cost reduction plan. See Note 15 to the Financial Statements for further discussion of these charges. Interest expense The increase in interest expense during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to an increase in the effective interest rate on our debt and interest expense of $2.4 million recorded for the settling of non-income-based tax debt during the current year period in connection with two Brazilian tax programs we entered into in 2017, partially offset by an increase in capitalized interest resulting from increased construction activities and a lower average balance of long-term debt and letters of credit outstanding. As discussed in Note 11 to the Financial Statements, the proceeds received in April 2017 from the issuance of the 2017 Notes were used to repay all of the borrowings outstanding under the term loan facility and revolving credit facility. For further discussion on the Brazilian tax programs, see Note 16 to the Financial Statements. Equity in income of non-consolidated affiliates In March 2012, our Venezuelan joint ventures sold their assets to PDVSA Gas, S.A. (“PDVSA Gas”). We received installment payments, including an annual charge of $10.4 million during the year ended December 31, 2016. As of December 31, 2017, the remaining principal amount due to us was approximately $4 million. Payments we receive from the sale are recognized as equity in income of non-consolidated affiliates in our statements of operations in the periods such payments are received. Other (income) expense, net The change in other (income) expense, net, was primarily due to foreign currency losses of $0.7 million during the year ended December 31, 2017 compared to foreign currency gains, net of foreign currency derivatives, of $5.8 million during the year ended December 31, 2016. Foreign currency gains and losses included translation gains of $0.5 million during the year ended December 31, 2017 compared to translation gains, net of foreign currency derivatives, of $8.6 million during the year ended December 31, 2016 related to the currency remeasurement of our foreign subsidiaries’ non-functional currency denominated intercompany obligations. The change in other (income) expense, net, was also due to penalties of $1.8 million incurred for the settling of non-income-based tax debt during the year ended December 31, 2017 in connection with the two Brazilian tax programs discussed above and a decrease of $0.5 million in gain on sale of property, plant and equipment. Income Taxes (dollars in thousands) Provision for income taxes Effective tax rate Years Ended December 31, 2017 2016 $ 22,695 $ 124,242 134.8% (261.4)% Increase (Decrease) (82)% 396.2 % For the year ended December 31, 2017, our provision for income tax and effective tax rate of 134.8% was positively impacted by the reversal of previously recorded valuation allowances of $5.6 million against our U.S. AMT carryforwards due to the Tax Reform Act which provided for the cancellation of the AMT and allows for a future refund and/or credit against regular income tax carryforwards. In addition, as a result of the reduction in the U.S. corporate tax rate from 35% to 21%, we recorded a provisional estimate of $15.5 million due to the re-measurement of deferred tax assets and liabilities and recorded a provisional estimate of $10.1 million due to the transition tax on undistributed earnings. Both of these were offset by a tax benefit from the reduction of the valuation allowance previously recorded against our U.S. deferred tax assets. Our effective tax rate was negatively impacted by a $17.1 million additional valuation allowance we recorded on our net U.S. deferred tax assets because beginning in 2016, we were no longer able to support that it was more likely-than-not that we would have sufficient taxable income in the future to realize our U.S. deferred tax assets. In addition, we recorded a $3.1 million benefit for the change in tax rates due to tax legislation enacted and signed into law in 2017 in Argentina. For further discussion on these new tax laws, see Note 16 to the Financial Statements. Our income tax expense for the year ended December 31, 2017 included benefits related to the reversal of valuation allowances previously recorded against deferred tax assets of $15.2 million related to income tax loss carryforwards that were utilized under two Brazilian tax programs. For the year ended December 31, 2016, our provision for income tax and effective tax rate of (261.4)% was adversely impacted by valuation allowances recorded against U.S. deferred tax assets and activity at our non-U.S. subsidiaries, which included valuation allowances against certain deferred tax assets, foreign currency devaluations and the settlement of a foreign audit. These negative impacts were partially offset by nontaxable Venezuelan joint venture proceeds and a net nontaxable capital contribution related to the Spin-off. Our effective tax rate is affected by recurring items, such as tax rates in foreign jurisdictions and the relative amounts of income we earn, or losses we incur, in those jurisdictions. It is also affected by discrete items that may occur in any given year but are not consistent from year to year. The following items had the most significant impact on the difference between our statutory U.S. federal income tax rate of 35.0% and our effective tax rate. For the year ended December 31, 2017: • A $48.1 million reduction (285.4% reduction) resulting from the release of valuation allowances primarily recorded against certain deferred tax assets of our foreign subsidiaries and federal net operating losses and credits in the U.S. • A $44.9 million increase (266.5% increase) resulting primarily from foreign withholding taxes, negative impacts of foreign currency devaluations in Argentina, and deemed distributions to the U.S. from certain of our non-U.S. subsidiaries. The increase includes a reduction resulting from rate differences between U.S. and foreign jurisdictions. • A $15.5 million increase (92.2% increase) resulting from changes to the tax rates at which certain deferred taxes are recorded due to U.S. tax reform legislation enacted and signed into law in 2017. • An $11.2 million reduction (66.7% reduction) resulting from claiming foreign taxes as credits primarily for foreign withholding taxes. The foreign tax credits are available to offset future payments of U.S. federal income taxes. • A $10.1 million increase (59.7% increase) resulting from transition tax charges related to U.S. tax reform legislation enacted and signed into law in 2017. For the year ended December 31, 2016: • A $124.9 million increase (262.7% reduction) resulting from valuation allowances primarily recorded against U.S. deferred tax assets and certain deferred tax assets of our subsidiary in Nigeria. • A $29.4 million increase (61.9% reduction) resulting primarily from foreign withholding taxes, negative impacts of foreign currency devaluations in Argentina and Mexico, settlement of a Nigeria tax audit and deemed distributions to the U.S. from certain of our non-U.S. subsidiaries. The increase includes a reduction resulting from rate differences between U.S. and foreign jurisdictions primarily related to income we earned in Oman and Mexico where the rates are 12.0% and 30.0%, respectively. • A $9.5 million reduction (20.0% increase) resulting from claiming foreign taxes as credits primarily for foreign withholding taxes. The foreign tax credits are available to offset future payments of U.S. federal income taxes. • A $3.6 million increase (7.6% reduction) resulting from unrecognized tax benefits primarily from additions based on tax positions related to 2016. • A $3.6 million reduction (7.7% increase) due to $10.4 million of nontaxable proceeds from sale of joint venture assets in Venezuela. • A $2.9 million reduction (6.1% increase) primarily due to $11.2 million of cash recovered from Archrock with respect to our restatement related charges. Payments between Archrock and us are treated as nontaxable capital contributions or distributions pursuant to the tax matters agreement. Discontinued Operations (dollars in thousands) Years Ended December 31, 2017 2016 Increase (Decrease) Income (loss) from discontinued operations, net of tax $ 39,736 $ (56,171) 171% Income (loss) from discontinued operations, net of tax, includes our Venezuelan subsidiary’s operations that were expropriated in June 2009, including compensation for expropriation, and our Belleli CPE and Belleli EPC businesses. Income from discontinued operations, net of tax, during the year ended December 31, 2017 compared to the year ended December 31, 2016 increased primarily due to asset impairment charges totaling $68.8 million recorded during the year ended December 31, 2016 for the planned disposition of Belleli CPE and a $42.8 million increase in income from Belleli EPC in 2017 compared to 2016 primarily due to recoveries in 2017 resulting from our release of liquidated damages by a customer in exchange for us releasing them from certain extension of time claims and the obtainment of customer approved change orders. These increases were partially offset by a $19.5 million decrease in income from our Venezuelan subsidiary. During the years ended December 31, 2017 and 2016, we received installment payments, including an annual charge, of $19.7 million and $38.8 million, respectively. As of December 31, 2017, the remaining principal amount due to us was approximately $17 million. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize payments received in the future as income from discontinued operations in the periods such payments are received. For further details on our discontinued operations, see Note 3 to the Financial Statements. Results of Operations The Year Ended December 31, 2016 Compared to the Year Ended December 31, 2015 Contract Operations (dollars in thousands) Revenue Cost of sales (excluding depreciation and amortization expense) Gross margin Gross margin percentage Years Ended December 31, 2016 392,463 143,670 248,793 $ $ 2015 469,900 172,391 297,509 $ $ 63% 63% Increase (Decrease) (16)% (17)% (16)% — % The decrease in revenue during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to a decrease in revenue of $34.3 million resulting from an early termination of a project in Indonesia in January 2016 that had been operating since the third quarter of 2009, a $33.0 million decrease in revenue in Mexico primarily driven by projects that terminated operations in 2015 and a reduction of recognized deferred revenue resulting from contract extensions and a $17.7 million decrease in revenue in Argentina primarily due to a devaluation of the Argentine peso since 2015. These decreases were partially offset by an $18.3 million increase in revenue in Brazil primarily driven by the start-up of a project during the second half of 2015. Gross margin decreased during the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily due to the revenue decrease described above, excluding the devaluation of the Argentine peso as the impact on gross margin was insignificant. Gross margin percentage during the year ended December 31, 2016 compared to the year ended December 31, 2015 remained flat. The early termination of a project in Indonesia resulted in additional costs during the years ended December 31, 2016 and 2015 in the form of depreciation expense, which is excluded from gross margin. Additionally, excluded from cost of sales and recorded to restructuring and other charges in our statements of operations during the year ended December 31, 2015 were non-cash inventory write-downs of $4.2 million associated with the Spin-off primarily related to the decentralization of shared inventory components between Archrock’s North America contract operations business and our international contract operations business. Aftermarket Services (dollars in thousands) Revenue Cost of sales (excluding depreciation and amortization expense) Gross margin Gross margin percentage Years Ended December 31, 2016 120,550 87,342 33,208 $ $ 2015 127,802 91,233 36,569 $ $ 28% 29% Increase (Decrease) (6)% (4)% (9)% (1)% The decrease in revenue during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to a decrease in revenue of $7.1 million in Gabon driven by our cessation of activities in the Gabon market during the first quarter of 2015. Gross margin decreased during the year ended December 31, 2016 compared to the year ended December 31, 2015 primarily due to the revenue decrease discussed above. Gross margin percentage during the year ended December 31, 2016 compared to the year ended December 31, 2015 decreased primarily due to the receipt of a settlement from a customer in Gabon during the year ended December 31, 2015, which positively impacted revenue and gross margin by $3.7 million and $2.2 million, respectively. Product Sales (dollars in thousands) Revenue Cost of sales (excluding depreciation and amortization expense) Gross margin Gross margin percentage Years Ended December 31, 2016 2015 Increase (Decrease) $ $ 392,384 $ 1,089,562 365,394 925,737 26,990 $ 163,825 7% 15% (64)% (61)% (84)% (8)% Overall, declines in our product sales bookings and backlog during driven by the market downturn resulted in revenue decreases during 2016 in each of the regions where we operate. During the year ended December 31, 2016 compared to the year ended December 31, 2015, revenue decreased by $528.2 million, $101.4 million and $67.6 million in North America, the Eastern Hemisphere and Latin America, respectively. The decrease in revenue in North America was due to decreases of $270.8 million, $212.1 million and $45.3 million in production and processing equipment revenue, compression equipment revenue and installation revenue, respectively. The decrease in the Eastern Hemisphere revenue was due to decreases of $40.4 million, $31.3 million and $29.7 million in installation revenue, compression equipment revenue and production and processing equipment revenue, respectively. The decrease in Latin America revenue was due to decreases of $35.6 million, $24.2 million and $7.8 million in compression equipment revenue, installation revenue and production and processing equipment revenue, respectively. The decreases in gross margin and gross margin percentage were primarily caused by the revenue decrease explained above, continued weakening market conditions resulting in a competitive pricing environment and an increase in under-absorption caused by reduced activities and management’s decision to maintain a certain level of manufacturing capacity. Excluded from cost of sales and recorded to restructuring and other charges in our statements of operations during the year ended December 31, 2015 were non-cash inventory write-downs of $4.5 million primarily related to our decision to exit the manufacturing of cold weather packages, which had historically been performed at a product sales facility in North America we decided to close. Costs and Expenses (dollars in thousands) Selling, general and administrative Depreciation and amortization Long-lived asset impairment Restatement related charges Restructuring and other charges Interest expense Equity in income of non-consolidated affiliates Other (income) expense, net Years Ended December 31, 2016 2015 Increase (Decrease) $ 157,485 $ 132,886 14,495 18,879 22,038 34,181 (10,403) (13,046) 210,483 146,318 20,788 — 31,315 7,272 (15,152) 35,516 (25)% (9)% (30)% N/A (30)% 370 % (31)% (137)% Selling, general and administrative The decrease in SG&A expense during the year ended December 31, 2016 compared to the year ended December 31, 2015 was driven by our cost reduction plan and included a $14.7 million decrease in international compensation and benefits costs and a $13.1 million decrease in corporate expenses. SG&A expense as a percentage of revenue was 17% and 12% during the years ended December 31, 2016 and 2015, respectively. The increase in SG&A expense as a percentage of revenue was primarily due to a significant decrease in product sales revenue during the year ended December 31, 2016 compared to the year ended December 31, 2015. For the periods prior to the Spin-off, SG&A expense includes expense allocations for certain functions, including allocations of expenses related to executive oversight, accounting, treasury, tax, legal, human resources, procurement and information technology services performed by Archrock on a centralized basis that historically have not been recorded at the segment level. These costs were allocated to us systematically based on specific department function and revenue. Included in SG&A expense during the year ended December 31, 2015 was $46.9 million of allocated corporate expenses incurred by Archrock. The actual costs we would have incurred if we had been a stand-alone public company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. Depreciation and amortization Depreciation and amortization expense during the year ended December 31, 2016 compared to the year ended December 31, 2015 decreased primarily due to a decrease of $16.5 million in depreciation expense on certain contract operations projects in Latin America primarily related to capitalized installation costs that were fully depreciated during 2016 and 2015. Capitalized installation costs, included, among other things, civil engineering, piping, electrical instrumentation and project management costs. Long-lived asset impairment We regularly review the future deployment of our idle compression assets used in our contract operations segment for units that are not of the type, configuration, condition, make or model that are cost efficient to maintain and operate. During the years ended December 31, 2016 and 2015, we determined that 62 idle compressor units and 93 idle compressor units, respectively, would be retired from the active fleet. The retirement of these units from the active fleet triggered a review of these assets for impairment. As a result, we recorded asset impairments of $12.7 million and $19.4 million during the years ended December 31, 2016 and 2015, respectively, to reduce the book value of each unit to its estimated fair value. During the year ended December 31, 2016, we evaluated other assets for impairment and recorded long-lived asset impairments of $1.7 million on these assets. During the first quarter of 2015, we evaluated a long-term note receivable from the purchaser of our Canadian Operations for impairment. This review was triggered by an offer from the purchaser of our Canadian Operations to prepay the note receivable at a discount to its then current book value. The fair value of the note receivable as of March 31, 2015 was based on the amount offered by the purchaser of our Canadian Operations to prepay the note receivable. The difference between the book value of the note receivable at March 31, 2015 and its fair value resulted in the recording of an impairment of long-lived assets of $1.4 million. In April 2015, we accepted the offer to early settle this note receivable. Restatement related charges As discussed in Note 14 to the Financial Statements, during the first quarter of 2016, our senior management identified errors relating to the application of percentage-of-completion accounting principles to specific Belleli EPC product sales projects. As a result, the Audit Committee of the Company’s Board of Directors initiated an internal investigation, including the use of services of a forensic accounting firm. Management also engaged a consulting firm to assist in accounting analysis and compilation of restatement adjustments. During the year ended December 31, 2016, we incurred $30.1 million of costs associated with the restatement of our financial statements and related SEC investigation, of which $11.2 million of cash was recovered from Archrock in the fourth quarter of 2016 pursuant to the separation and distribution agreement. Restructuring and other charges In the second quarter of 2015, we announced a cost reduction plan, primarily focused on workforce reductions and the reorganization of certain facilities. These actions were in response to unfavorable market conditions in North America combined with the impact of lower international activity due to customer budget cuts driven by lower oil prices. During the year ended December 31, 2016, we incurred $18.1 million of restructuring and other charges as a result of this plan, which were primarily related to $14.5 million of employee termination benefits and a $2.9 million charge for the exit of a corporate building under an operating lease. During the year ended December 31, 2015, we incurred $15.6 million of restructuring and other charges as a result of this plan, which were primarily related to $9.6 million of employee termination benefits and $4.0 million of non-cash write-downs of inventory. The non-cash inventory write-downs were the result of our decision to exit the manufacturing of cold weather packages, which had historically been performed at a product sales facility in North America we decided to close in 2015. Additionally, we incurred restructuring and other charges associated with the Spin-off. During the year ended December 31, 2016, we incurred $3.9 million of costs associated with the Spin-off, which were primarily related to expenses of $3.1 million for retention awards to certain employees. During the year ended December 31, 2015, we incurred $15.7 million of costs associated with the Spin-off, which were primarily related to non-cash inventory write-downs of $4.7 million, financial advisor fees of $4.6 million paid at the completion of the Spin-off, expenses of $3.1 million for retention awards to certain employees and a one-time cash signing bonus of $2.0 million paid to our Chief Executive Officer. Non-cash inventory write-downs were primarily related to the decentralization of shared inventory components between Archrock’s North America contract operations business and our international contract operations business. The charges incurred in conjunction with the cost reduction plan and Spin-off are included in restructuring and other charges in our statements of operations. See Note 15 to the Financial Statements for further discussion of these charges. Interest expense The increase in interest expense during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to borrowings under our revolving credit facility and term loan facility (collectively, the “Credit Facility”) that became available on November 3, 2015. During the year ended December 31, 2016, the average daily outstanding borrowings under the Credit Facility were $422.9 million. Prior to the Spin-off, third party debt of Archrock, other than debt attributable to capital leases, was not allocated to us as we were not the legal obligor of the debt and Archrock’s borrowings were not directly attributable to our business. Equity in income of non-consolidated affiliates In March 2012, our Venezuelan joint ventures sold their assets to PDVSA Gas. We received installment payments, including an annual charge, of $10.4 million and $15.2 million during the years ended December 31, 2016 and 2015, respectively. Payments we receive from the sale will be recognized as equity in income of non-consolidated affiliates in our statements of operations in the periods such payments are received. Other (income) expense, net The change in other (income) expense, net, during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to foreign currency gains, net of losses on foreign currency derivatives, of $5.8 million during the year ended December 31, 2016 compared to foreign currency losses of $35.8 million during the year ended December 31, 2015. Our foreign currency gains and losses included translation gains, net of losses on foreign currency derivatives, of $8.6 million during the year ended December 31, 2016 compared to translation losses of $30.1 million during the year ended December 31, 2015 related to the currency remeasurement of our foreign subsidiaries’ non-functional currency denominated intercompany obligations. Of the foreign currency losses recognized during the year ended December 31, 2015, $29.7 million was attributable to our Brazil subsidiary’s U.S. dollar denominated intercompany obligations and were the result of a currency devaluation in Brazil and increases in our Brazil subsidiary’s intercompany payables 2015. The change in other (income) expense, net, was also due to a $4.9 million loss recognized during 2015 on short-term investments related to the purchase of $18.4 million of Argentine government issued U.S. dollar denominated bonds using Argentine pesos. Income Taxes (dollars in thousands) Provision for income taxes Effective tax rate Years Ended December 31, 2016 2015 $ 124,242 $ 39,438 (261.4)% 64.3% Increase (Decrease) 215 % (325.7)% For the year ended December 31, 2016, our effective tax rate of (261.4)% was adversely impacted by valuation allowances recorded against U.S. deferred tax assets and activity at our non-U.S. subsidiaries, which included valuation allowances against certain deferred tax assets, foreign currency devaluations and the settlement of a foreign audit. These negative impacts were partially offset by nontaxable Venezuelan joint venture proceeds and a net nontaxable capital contribution related to the Spin- off. For the year ended December 31, 2015, our effective tax rate of 64.3% was adversely impacted by activity at our non-U.S. subsidiaries, which included valuation allowances recorded against certain net operating losses, foreign currency devaluations, foreign dividend withholding taxes and deemed distributions to the U.S. These negative impacts were partially offset by tax benefits related to claiming the research and development credit (the “R&D Credit”) and nontaxable Venezuelan joint venture proceeds. Our effective tax rate is affected by recurring items, such as tax rates in foreign jurisdictions and the relative amounts of income we earn, or losses we incur, in those jurisdictions. It is also affected by discrete items that may occur in any given year but are not consistent from year to year. In addition to net state income taxes, the following items had the most significant impact on the difference between our statutory U.S. federal income tax rate of 35.0% and our effective tax rate. For the year ended December 31, 2016: • A $124.9 million increase (262.7% reduction) resulting from valuation allowances primarily recorded against U.S. deferred tax assets and certain deferred tax assets of our subsidiary in Nigeria. • A $29.4 million increase (61.9% reduction) resulting primarily from foreign withholding taxes, negative impacts of foreign currency devaluations in Argentina and Mexico, settlement of a Nigeria tax audit and deemed distributions to the U.S. from certain of our non-U.S. subsidiaries. The increase includes a reduction resulting from rate differences between U.S. and foreign jurisdictions primarily related to income we earned in Oman and Mexico where the rates are 12.0% and 30.0%, respectively. • A $9.5 million reduction (20.0% increase) resulting from claiming foreign taxes as credits primarily for foreign withholding taxes. The foreign tax credits are available to offset future payments of U.S. federal income taxes. • A $3.6 million increase (7.6% reduction) resulting from unrecognized tax benefits primarily from additions based on tax positions related to 2016. • A $3.6 million reduction (7.7% increase) due to $10.4 million of nontaxable proceeds from sale of joint venture assets in Venezuela. • A $2.9 million reduction (6.1% increase) primarily due to $11.2 million of cash recovered from Archrock with respect to our restatement related charges. Payments between Archrock and us are treated as nontaxable capital contributions or distributions pursuant to the tax matters agreement. For the year ended December 31, 2015: • A $39.0 million increase (63.5% increase) resulting primarily from foreign withholding taxes, negative impacts of foreign currency devaluations in Argentina and Mexico and deemed distributions to the U.S. from certain of our non- U.S. subsidiaries. The increase includes a reduction resulting from rate differences between U.S. and foreign jurisdictions primarily related to income we earned in Oman, Mexico and Thailand where the rates are 12.0%, 30.0% and 20.0%, respectively. • A $20.0 million increase (32.5% increase) resulting from valuation allowances primarily recorded against deferred tax assets of our subsidiaries in Brazil and the Netherlands. • A $24.9 million reduction (40.6% reduction) resulting from claiming the R&D Credit for years 2009 through 2013. The R&D Credits are available to offset future payments of U.S. federal income taxes. • A $17.4 million reduction (28.4% reduction) resulting from claiming foreign taxes as credits primarily for foreign withholding taxes. The foreign tax credits are available to offset future payments of U.S. federal income taxes. • A $6.0 million increase (9.8% increase) resulting from unrecognized tax benefits primarily related to additions based on tax positions related to 2015. • A $5.3 million reduction (8.7% reduction) due to $15.2 million of nontaxable proceeds from sale of joint venture assets in Venezuela. Discontinued Operations (dollars in thousands) Years Ended December 31, 2016 2015 Increase (Decrease) Income (loss) from discontinued operations, net of tax $ (56,171) $ 4,723 (1,289)% Income (loss) from discontinued operations, net of tax, includes our Venezuelan subsidiary’s operations that were expropriated in June 2009, including compensation for expropriation, and our Belleli CPE and Belleli EPC businesses. Loss from discontinued operations, net of tax, during the year ended December 31, 2016 compared to the year ended December 31, 2015 increased primarily due to asset impairment charges totaling $68.8 million recorded during the year ended December 31, 2016 for the planned disposition of Belleli CPE and a $17.1 million decrease in income from our Venezuelan subsidiary in 2016 compared to 2015, partially offset by a $27.5 million decrease in loss from Belleli EPC in 2016 compared to 2015 primarily caused by estimated loss contract provisions of $30.1 million recorded on significant projects during 2015 that were driven by project execution delays. The reduction in income from our Venezuelan subsidiary was primarily related to payments from PDVSA Gas to our Venezuelan subsidiary. During the years ended December 31, 2016 and 2015, we received installment payments, including an annual charge, totaling $38.8 million and $56.6 million, respectively. For further details on our discontinued operations, see Note 3 to the Financial Statements. Liquidity and Capital Resources Our unrestricted cash balance was $49.1 million at December 31, 2017 compared to $35.7 million at December 31, 2016. Working capital decreased to $134.0 million at December 31, 2017 from $177.8 million at December 31, 2016. The decrease in working capital was primarily due to increases in accounts payable and billings on uncompleted contracts in excess of costs and estimated earnings and a decrease in inventory, partially offset by increases in accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts and a decrease in current liabilities associated with discontinued operations. The increases in accounts payable, billings on uncompleted contracts in excess of costs and estimated earnings, accounts receivable and costs and estimated earnings in excess of billings on uncompleted contracts were primarily driven by higher product sales activity in North America. The decrease in current liabilities associated with discontinued operations was primarily due to substantially exiting our Belleli EPC business in the fourth quarter of 2017. The decrease in inventory was primarily due to the reclassification of inventory to current assets held for sale related to certain inventory within our products sales business that we expect to sell within the next twelve months, a decrease in product sales inventory resulting from recent activities in North America and the utilization of inventory on capital projects during the current year period. Our cash flows from operating, investing and financing activities, as reflected in the statements of cash flows, are summarized in the table below (in thousands): Net cash provided by (used in) continuing operations: Operating activities Investing activities Financing activities Effect of exchange rate changes on cash and cash equivalents Discontinued operations Net change in cash and cash equivalents Years Ended December 31, 2017 2016 $ $ 150,420 (121,788) (32,154) (792) 17,781 262,489 (60,343) (230,763) (1,832) 37,095 $ 13,467 $ 6,646 Operating Activities. The decrease in net cash provided by operating activities during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily attributable to lower current period decreases in working capital, partially offset by improved gross margins for our product sales segment. Working capital changes during the year ended December 31, 2017 included an increase of $62.0 million in accounts payable and other liabilities, an increase of $65.3 million in accounts receivable and a decrease of $40.9 million in costs and estimated earnings versus billings on uncompleted contracts. Working capital changes during the year ended December 31, 2016 included a decrease of $126.3 million in accounts receivable, a decrease of $49.7 million in inventory, a decrease of $24.6 million in costs and estimated earnings versus billings on uncompleted contracts. Investing Activities. The increase in net cash used in investing activities during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily attributable to a $58.0 million increase in capital expenditures and a $10.4 million decrease in proceeds received from the sale of our joint ventures’ previously nationalized assets, partially offset by a $6.1 million increase in proceeds from the sale of property, plant and equipment. Financing Activities. The decrease in net cash used in financing activities during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily attributable to a decrease in net repayments of $204.1 million and a $4.5 million decrease in cash transferred to Archrock pursuant to the separation and distribution agreement, partially offset by a $7.1 million increase in debt issuance costs. The transfers of cash to Archrock during the years ended December 31, 2017 and 2016 were triggered by our receipt of payments from PDVSA Gas relating to the sale of our and our joint ventures’ previously nationalized assets and the repayment of $25.0 million after our occurrence of a qualified capital raise as required under the separation and distribution agreement. Discontinued Operations. The decrease in net cash provided by discontinued operations during the year ended December 31, 2017 compared to year ended December 31, 2016 was primarily attributable to a $19.1 million decrease in proceeds received from the sale of our Venezuelan subsidiary’s assets to PDVSA Gas and cash proceeds of $5.5 million received from the sale of our Belleli CPE business in August 2016, partially offset by working capital changes related to our Belleli CPE business in 2016. Capital Requirements. Our contract operations business is capital intensive, requiring significant investment to maintain and upgrade existing operations. Our capital spending is primarily dependent on the demand for our contract operations services and the availability of the type of equipment required for us to render those contract operations services to our customers. Our capital requirements have consisted primarily of, and we anticipate will continue to consist of, the following: • growth capital expenditures, which are made to expand or to replace partially or fully depreciated assets or to expand the operating capacity or revenue generating capabilities of existing or new assets, whether through construction, acquisition or modification; and • maintenance capital expenditures, which are made to maintain the existing operating capacity of our assets and related cash flows further extending the useful lives of the assets. The majority of our growth capital expenditures are related to installation costs on integrated projects and acquisition costs of new compressor units and processing and treating equipment that we add to our contract operations fleet. In addition, growth capital expenditures can include the upgrading of major components on an existing compressor unit where the current configuration of the compressor unit is no longer in demand and the compressor unit is not likely to return to an operating status without the capital expenditures. These latter expenditures substantially modify the operating parameters of the compressor unit such that it can be used in applications for which it previously was not suited. Maintenance capital expenditures are related to major overhauls of significant components of a compressor unit, such as the engine, compressor and cooler, that return the components to a “like new” condition, but do not modify the applications for which the compressor unit was designed. Growth capital expenditures were $104.9 million, $53.0 million and $105.2 million during the years ended December 31, 2017, 2016 and 2015, respectively. The increase in growth capital expenditures during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to an increase in installation expenditures on integrated projects in Oman during 2017. The decrease in growth capital expenditures during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to a decrease in installation expenditures on integrated projects in Bolivia and Brazil. Maintenance capital expenditures were $15.7 million, $14.4 million and $27.3 million during the years ended December 31, 2017, 2016 and 2015, respectively. The increase in maintenance capital expenditures during the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily driven by increased overhaul activities. The decrease in maintenance capital expenditures during the year ended December 31, 2016 compared to the year ended December 31, 2015 was primarily due to delayed discretionary spending as a result of the market downturn. Historically, maintenance capital expenditures have remained relatively flat from year to year primarily as a result of routine scheduled overhaul activities. We intend to grow our business both organically and through third-party acquisitions. If we are successful in growing our business in the future, we would expect our maintenance capital expenditures to increase over the long term. We generally invest funds necessary to manufacture contract operations fleet additions when our idle equipment cannot be reconfigured to economically fulfill a project’s requirements and the new equipment expenditure is expected to generate economic returns over its expected useful life that exceeds our targeted return on capital. We currently plan to spend approximately $240 million to $300 million in capital expenditures during 2018, including (1) approximately $200 million to $250 million on contract operations growth capital expenditures and (2) approximately $20 million to $40 million on equipment maintenance capital related to our contract operations business. Long-Term Debt. We and our wholly owned subsidiary, EESLP, are parties to an amended and restated credit agreement (the “Credit Agreement”) consisting of a $680.0 million revolving credit facility expiring in November 2020 and previously included a term loan facility. In April 2017, we paid the remaining principal amount of $232.8 million due under the term loan facility with proceeds from the 2017 Notes (as described below) issuance. During the years ended December 31, 2017 and 2016, the average daily borrowings under the term loan facility and revolving credit facility were $87.9 million and $422.9 million, respectively. The weighted average annual interest rate on outstanding borrowings under the revolving credit facility at December 31, 2016 was 5.0%. The annual interest rate on the outstanding balance of the term loan facility at December 31, 2016 was 6.8%. As of December 31, 2017, there were no outstanding borrowings under the revolving credit facility. As of December 31, 2017, we had $39.7 million in outstanding letters of credit under our revolving credit facility and, taking into account guarantees through letters of credit, we had undrawn capacity of $640.3 million under our revolving credit facility. Our Credit Agreement limits our Total Debt to EBITDA ratio (as defined in the Credit Agreement) on the last day of the fiscal quarter to no greater than 4.50 to 1.0. As a result of this limitation, $585.2 million of the $640.3 million of undrawn capacity under our revolving credit facility was available for additional borrowings as of December 31, 2017. The Credit Agreement contains various covenants with which we, EESLP and our respective restricted subsidiaries must comply, including, but not limited to, limitations on the incurrence of indebtedness, investments, liens on assets, repurchasing equity, making distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. We are required to maintain, on a consolidated basis, a minimum interest coverage ratio (as defined in the Credit Agreement) of 2.25 to 1.00; a maximum total leverage ratio (as defined in the Credit Agreement) of 4.50 to 1.00; and a maximum senior secured leverage ratio (as defined in the Credit Agreement) of 2.75 to 1.00. As of December 31, 2017, Exterran Corporation maintained an 8.3 to 1.0 interest coverage ratio and a 1.7 to 1.0 total leverage ratio. As of December 31, 2017, we were in compliance with all financial covenants under the Credit Agreement. In April 2017, our 100% owned subsidiaries EESLP and EES Finance Corp. issued the 2017 Notes, which consists of $375.0 million aggregate principal amount of senior unsecured notes. The 2017 Notes are guaranteed by us on a senior unsecured basis. The net proceeds of $367.1 million from the 2017 Notes issuance were used to repay all of the borrowings outstanding under the term loan facility and revolving credit facility and for general corporate purposes. Additionally, pursuant to the separation and distribution agreement from the Spin-off, EESLP used proceeds from the issuance of the 2017 Notes to pay a subsidiary of Archrock $25.0 million in satisfaction of EESLP’s obligation to pay that sum following the occurrence of a qualified capital raise. The transfer of cash to Archrock’s subsidiary was recognized as a reduction to additional paid-in capital during the year ended December 31, 2017. We may from time to time seek to retire or purchase our outstanding debt through cash purchases and/or exchanges for equity securities, in open market purchases, privately negotiated transactions or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material. Historically, we have financed capital expenditures primarily with net cash provided by operating activities. Our ability to access the capital markets may be restricted at the time when we would like, or need, to do so, which could have an adverse impact on our ability to maintain our operations and to grow. If any of our lenders become unable to perform their obligations under the Credit Agreement, our borrowing capacity under our revolving credit facility could be reduced. Inability to borrow additional amounts under our revolving credit facility could limit our ability to fund our future growth and operations. Based on current market conditions, we expect that net cash provided by operating activities and borrowings under our revolving credit facility will be sufficient to finance our operating expenditures, capital expenditures and other contractual cash obligations, including our debt obligations. However, if net cash provided by operating activities and borrowings under our revolving credit facility are not sufficient, we may seek additional debt or equity financing. Contingencies to Archrock. Pursuant to the separation and distribution agreement, EESLP contributed to a subsidiary of Archrock the right to receive payments based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries until Archrock’s subsidiary has received an aggregate amount of such payments up to the lesser of (i) $125.8 million, plus the aggregate amount of all reimbursable expenses incurred by Archrock and its subsidiaries in connection with recovering any PDVSA Gas default installment payments following the completion of the Spin- off or (ii) $150.0 million. Our balance sheets do not reflect this contingent liability to Archrock or the amount payable to us by PDVSA Gas as a receivable. Pursuant to the separation and distribution agreement, we transferred cash of $19.7 million and $49.2 million to Archrock during the years ended December 31, 2017 and 2016, respectively. The transfers of cash were recognized as reductions to additional paid-in capital in our financial statements. As of December 31, 2017, the remaining principal amount due to us from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets was approximately $21 million. Unrestricted Cash. Of our $49.1 million unrestricted cash balance at December 31, 2017, $25.0 million was held by our non- U.S. subsidiaries. In the event of a distribution of earnings to the U.S. in the form of dividends, we may be subject to foreign withholding taxes. We do not believe that the cash held by our non-U.S. subsidiaries has an adverse impact on our liquidity because we expect that the cash we generate in the U.S., the available borrowing capacity under our revolving credit facility and the repayment of intercompany liabilities from our non-U.S. subsidiaries will be sufficient to fund the cash needs of our U.S. operations for the foreseeable future. Dividends. We do not currently anticipate paying cash dividends on our common stock. We currently intend to retain our future earnings to support the growth and development of our business. The declaration of any future cash dividends and, if declared, the amount of any such dividends, will be subject to our financial condition, earnings, capital requirements, financial covenants, applicable law and other factors our board of directors deems relevant. Contractual Obligations. The following table summarizes our cash contractual obligations as of December 31, 2017 and the effect such obligations are expected to have on our liquidity and cash flow in future periods (in thousands): Long-term debt:(1) 8.125% senior notes due May 2025 (2) Other Total long-term debt Interest on long-term debt Purchase commitments Facilities and other operating leases Total contractual obligations Total 2018 2019-2020 2021-2022 Thereafter $ 375,000 $ — $ — $ — $ 375,000 722 375,722 238,713 364,776 23,852 — — 34,840 364,670 4,759 722 722 69,309 106 4,628 — — 60,938 — 3,785 — 375,000 73,626 — 10,680 $ 1,003,063 $ 404,269 $ 74,765 $ 64,723 $ 459,306 (1) (2) For more information on our long-term debt, see Note 11 to the Financial Statements. Amounts represent the full face value of the 2017 Notes and do not include unamortized debt financing costs of $7.3 million as of December 31, 2017. As of December 31, 2017, $20.5 million of unrecognized tax benefits (including discontinued operations) have been recorded as liabilities in accordance with the accounting standard for income taxes related to uncertain tax positions, and we are uncertain as to if or when such amounts may be settled. Related to these unrecognized tax benefits, we have also recorded a liability for potential penalties and interest (including discontinued operations) of $4.3 million. Indemnifications. In conjunction with, and effective as of the completion of, the Spin-off, we entered into the separation and distribution agreement with Archrock, which governs, among other things, the treatment between Archrock and us of aspects relating to certain aspects of indemnification, insurance, confidentiality and cooperation. Generally, the separation and distribution agreement provides for cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of our business with us and financial responsibility for the obligations and liabilities of Archrock’s business with Archrock. Pursuant to the agreement, we and Archrock will generally release the other party from all claims arising prior to the Spin-off that relate to the other party’s business, subject to certain exceptions. Additionally, in conjunction with, and effective as of the completion of, the Spin-off, we entered into the tax matters agreement with Archrock. Under the tax matters agreement and subject to certain exceptions, we are generally liable for, and indemnify Archrock against, taxes attributable to our business, and Archrock is generally liable for, and indemnify us against, all taxes attributable to its business. We are generally liable for, and indemnify Archrock against, 50% of certain taxes that are not clearly attributable to our business or Archrock’s business. Any payment made by us to Archrock, or by Archrock to us, is treated by all parties for tax purposes as a nontaxable distribution or capital contribution, respectively, made immediately prior to the Spin-off. Off-Balance Sheet Arrangements We have no material off-balance sheet arrangements. Effects of Inflation Our revenues and results of operations have not been materially impacted by inflation in the past three fiscal years. Critical Accounting Policies, Practices and Estimates This discussion and analysis of our financial condition and results of operations is based upon the Financial Statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates and accounting policies, including those related to bad debt, inventories, fixed assets, intangible assets, income taxes, revenue recognition, contingencies and litigation. We base our estimates on historical experience and on other assumptions that we believe are reasonable under the circumstances. The results of this process form the basis of our judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions, and these differences can be material to our financial condition, results of operations and liquidity. See Note 2 to our Financial Statement for a summary of significant accounting policies. Allowances and Reserves We maintain allowances for doubtful accounts for estimated losses resulting from the inability of our customers to make required payments. The determination of the collectability of amounts due from our customers requires us to use estimates and make judgments regarding future events and trends, including monitoring our customers’ payment history and current creditworthiness to determine that collectibility is reasonably assured, as well as consideration of the overall business climate in which our customers operate. Inherently, these uncertainties require us to make judgments and estimates regarding our customers’ ability to pay amounts due to us in order to determine the appropriate amount of valuation allowances required for doubtful accounts. We review the adequacy of our allowance for doubtful accounts quarterly. We determine the allowance needed based on historical write-off experience and by evaluating significant balances aged greater than 90 days individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. During the years ended December 31, 2017, 2016 and 2015, we recorded bad debt expense of $0.9 million, $3.0 million and $3.3 million, respectively. Our allowance for doubtful accounts was approximately 2% and 3% of our gross accounts receivable balance at December 31, 2017 and 2016, respectively. Inventory is a significant component of current assets and is stated at the lower of cost and net realizable value. This requires us to record provisions and maintain reserves for obsolete and slow moving inventory. To determine these reserve amounts, we regularly review inventory quantities on hand and compare them to estimates of future product demand, market conditions and production requirements. These estimates and forecasts inherently include uncertainties and require us to make judgments regarding potential outcomes. During 2017, 2016 and 2015, we recorded $1.3 million, $0.8 million and $15.6 million, respectively, in inventory write-downs and reserves for inventory which was obsolete or slow moving. As discussed further in Note 15 to the Financial Statements, during the year ended December 31, 2015, we recorded restructuring and other charges of $8.7 million related to inventory write-downs associated with restructuring activities. Significant or unanticipated changes to our estimates and forecasts could impact the amount and timing of any additional provisions for obsolete or slow moving inventory that may be required. Our reserve for obsolete and slow moving inventory was approximately 11% of our gross raw materials inventory balance at December 31, 2017 and 2016. Depreciation Property, plant and equipment is carried at cost. Depreciation for financial reporting purposes is computed on a straight-line basis using estimated useful lives and salvage values, including idle assets in our active fleet. The assumptions and judgments we use in determining the estimated useful lives and salvage values of our property, plant and equipment reflect both historical experience and expectations regarding future use of our assets. We periodically analyze our estimates of useful lives of our property, plant and equipment to determine if the depreciable periods and salvage values continue to be appropriate. The use of different estimates, assumptions and judgments in the establishment of property, plant and equipment accounting policies, especially those involving their useful lives, would likely result in significantly different net book values of our assets and results of operations. In the fourth quarter of 2017, we evaluated the estimated useful lives and salvage values of our property, plant and equipment. As a result of this evaluation, we changed the useful lives and salvage values for our compression equipment from a maximum useful life of 30 years to 23 years and a maximum salvage value of 20% to 15% based on expected future use. During the year ended December 31, 2017, we recorded a $1.2 million increase in depreciation expense as a result of these changes in useful lives and salvage values. Additionally, these policy changes are expected to increase our depreciation expense, relative to the previous depreciation schedule of the impacted compression equipment, for the year ended December 31, 2018 by approximately $9.0 million. Long-Lived Assets We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable. Compressor units in our active fleet that were idle as of December 31, 2017 comprise a net book value of approximately $77.7 million. The determination that the carrying amount of an asset may not be recoverable requires us to make judgments regarding long-term forecasts of future revenue and costs related to the assets subject to review. For idle compression units that are removed from the active fleet and that will be sold to third parties as working compression units, significant assumptions include forecasted sale prices based on future market conditions and demand, forecasted costs to maintain the assets until sold and the forecasted length of time necessary to sell the assets. These forecasts are uncertain as they require significant assumptions about future market conditions. Significant and unanticipated changes to these assumptions could require a provision for impairment in a future period. Given the nature of these evaluations and their application to specific assets and specific times, it is not possible to reasonably quantify the impact of changes in these assumptions. An impairment loss exists when estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. When necessary, an impairment loss is recognized and represents the excess of the asset’s carrying value as compared to its estimated fair value and is charged to the period in which the impairment occurred. Income Taxes Our income tax provision, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect management’s best assessment of estimated current and future taxes to be paid. We operate in approximately 30 countries and, as a result, we and our subsidiaries file consolidated and separate income tax returns in the U.S. federal jurisdiction and in numerous state and foreign jurisdictions. In addition, certain of our operations were historically included in Archrock’s consolidated income tax returns in the U.S. federal and state jurisdictions. Our tax provision for periods prior to the Spin-off was determined on a separate return, stand-alone basis. Differences between the separate return method utilized and Archrock’s U.S. income tax returns and cash flows attributable to income taxes for our U.S. operations were recognized as distributions to, or contributions from, parent within parent equity. Significant judgments and estimates are required in determining our consolidated income tax provision. Deferred income taxes arise from temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities. In evaluating our ability to recover our deferred tax assets within the jurisdiction from which they arise, we consider all available positive and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax-planning strategies and results of recent operations. In projecting future taxable income, we begin with historical results adjusted for the results of discontinued operations and changes in accounting policies and incorporate assumptions including the amount of future U.S. federal, state and foreign pretax operating income, the reversal of temporary differences and the implementation of feasible and prudent tax-planning strategies. These assumptions require significant judgment about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage the underlying businesses. In evaluating the objective evidence that historical results provide, we consider three years of cumulative operating income (loss). The accounting standard for income taxes provides that a tax benefit from an uncertain tax position is only recognized when it is more-likely-than-not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of the technical merits. In addition, guidance is provided on measurement, derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. We adjust reserves for unrecognized tax benefits when our judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the tax liabilities. These differences will be reflected as increases or decreases to income tax provision in the period in which new information is available. We consider the earnings of our non-U.S. subsidiaries to be indefinitely invested outside the U.S. Should we decide to repatriate any unremitted foreign earnings, we would have to adjust the income tax provision in the period we determined that such earnings will no longer be indefinitely invested outside the U.S. On December 22, 2017, the U.S. government enacted comprehensive tax legislation. The Tax Reform Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) eliminating the corporate AMT and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax, a new minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. Guidance under U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Reform Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. While we recorded provisional estimates of the impact of the Tax Reform Act, the final impact may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the government and actions we may take as a result of these enacted tax laws. We are continuing to analyze additional information to determine the final impact as well as other impacts of the Tax Reform Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our 2018 financial statements. For further information on the tax impacts of the Tax Reform Act, see Note 16 to the Financial Statements. Revenue Recognition — Percentage-of-Completion Accounting We recognize revenue and profit for our product sales operations as work progresses on long-term contracts using the percentage-of-completion method when the applicable criteria are met. During the years ended December 31, 2017, 2016 and 2015, we recognized approximately 87%, 80% and 70%, respectively, of our total product sales revenues from third parties using the percentage-of-completion method. The percentage-of-completion method depends largely on the ability to make reasonably dependable estimates related to the extent of progress toward completion of the contract, contract revenues and contract costs. Recognized revenues and profit are subject to revisions as the contract progresses to completion. Revisions in profit estimates are charged to income in the period in which the facts that give rise to the revision become known. The typical duration of these projects is three to 24 months. If we determine that a contract will result in a loss, we record a provision for the entire amount of the estimated loss in the period in which the loss is identified. Due to the long-term nature of some of our projects, developing the estimates of costs often requires significant judgment. We estimate percentage-of-completion for compressor and production and processing equipment product sales on a direct labor hour to total labor hour basis. This calculation requires management to estimate the number of total labor hours required for each project and to estimate the profit expected on the project. Because we have many product sales projects in process at any given time, we do not believe that materially different results would be achieved if different estimates, assumptions or conditions were used for any single project. Factors that must be considered in estimating the work to be completed and ultimate profit include labor productivity and availability, the nature and complexity of work to be performed, the impact of change orders, availability of raw materials and the impact of delayed performance. Although we continually strive to accurately estimate our progress toward completion and profitability, adjustments to overall contract revenue and contract costs could be significant in future periods due to several factors including but not limited to, settlement of claims against customers, vendor claims by or against us, customer change orders, changes in cost estimates, changes in project contingencies and settlement of customer claims against us, such as liquidated damage claims. If the aggregate combined cost estimates for uncompleted contracts that are recognized using the percentage-of-completion method in our product sales business had been higher or lower by 5% in 2017, our income before income taxes would have decreased or increased by approximately $15.7 million. Accrued loss contract provisions are included in accrued liabilities in our balance sheets. Contingencies and Litigation We are substantially self-insured for workers’ compensation, employer’s liability, property, auto liability, general liability and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. We review these estimates quarterly and believe such accruals to be adequate. However, insurance liabilities are difficult to estimate due to unknown factors, including the severity of an injury, the determination of our liability in proportion to other parties, the timeliness of reporting of occurrences, ongoing treatment or loss mitigation, general trends in litigation recovery outcomes and the effectiveness of safety and risk management programs. Therefore, if our actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and would be recorded in the period in which the difference becomes known. As of December 31, 2017 and 2016, we had recorded approximately $1.3 million and $1.1 million, respectively, in insurance claim reserves. In the ordinary course of business, we are involved in various pending or threatened legal actions. While we are unable to predict the ultimate outcome of these actions, the accounting standard for contingencies requires management to make judgments about future events that are inherently uncertain. We are required to record (and have recorded) a loss during any period in which we believe a loss contingency is probable and can be reasonably estimated. In making determinations of likely outcomes of pending or threatened legal matters, we consider the evaluation of counsel knowledgeable about each matter. We regularly assess and, if required, establish accruals for income tax as well as non-income-based tax contingencies pursuant to the applicable accounting standards that could result from assessments of additional tax by taxing jurisdictions in countries where we operate. Tax contingencies are subject to a significant amount of judgment and are reviewed and adjusted on a quarterly basis in light of changing facts and circumstances considering the outcome expected by management. As of December 31, 2017 and 2016, we had recorded approximately $27.6 million and $24.3 million, respectively, of accruals for tax contingencies (including penalties and interest and discontinued operations). Of these amounts, $24.8 million and $21.2 million are accrued for income taxes as of December 31, 2017 and 2016, respectively, and $2.8 million and $3.1 million are accrued for non-income-based taxes as of December 31, 2017 and 2016, respectively. Furthermore, as of December 31, 2017 and 2016, we had an indemnification receivable from Archrock related to non-income-based taxes of $1.5 million and $1.7 million, respectively. If our actual experience differs from the assumptions and estimates used for recording the liabilities, adjustments may be required and would be recorded in the period in which the difference becomes known. Recent Accounting Pronouncements See Note 2 to the Financial Statements. Item 7A. Quantitative and Qualitative Disclosures About Market Risk We are exposed to market risks associated with changes in foreign currency exchange rates due to our significant international operations. The net assets and liabilities of these operations are exposed to changes in currency exchange rates. These operations may also have net assets and liabilities not denominated in their functional currency, which exposes us to changes in foreign currency exchange rates that impact income. We currently do not have any derivative financial instruments outstanding to mitigate foreign currency risk. In the future, we may utilize derivative instruments to manage the risk of fluctuations in foreign currency exchange rates that could potentially impact our future earnings and forecasted cash flows. We recorded foreign currency losses of $0.7 million and foreign currency gains of $6.5 million in our statements of operations during the years ended December 31, 2017 and 2016, respectively. Our foreign currency gains and losses are primarily due to exchange rate fluctuations related to monetary asset balances denominated in currencies other than the functional currency, including foreign currency exchange rate changes recorded on intercompany obligations. Our material exchange rate exposure relates to intercompany loans to a subsidiary whose functional currency is the Brazilian Real, which loans carried balances of $27.7 million U.S. dollars as of December 31, 2017. Foreign currency gains and losses during the years ended December 31, 2017 and 2016 included translation gains of $0.5 million and $9.3 million, respectively, related to the functional currency remeasurement of our foreign subsidiaries’ non-functional currency denominated intercompany obligations. Additionally, during the year ended December 31, 2016, we recognized a loss of $0.7 million on forward currency exchange contracts that offset exchange rate exposure related to intercompany loans to a subsidiary whose functional currency is the Brazilian Real. Changes in exchange rates may create gains or losses in future periods to the extent we maintain net assets and liabilities not denominated in the functional currency. Item 8. Financial Statements and Supplementary Data The consolidated and combined financial statements and supplementary information specified by this Item are presented in Part IV, Item 15 (“Exhibits and Financial Statement Schedules”) of this report. Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure None. Item 9A. Controls and Procedures This Item 9A includes information concerning the controls and controls evaluation referred to in the certifications of our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”) required by Rule 13a-14 of the Exchange Act included in this Annual Report as Exhibits 31.1 and 31.2. Management’s Evaluation of Disclosure Controls and Procedures The CEO and CFO have reviewed and evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), as of the end of the fiscal year for which this annual report on Form 10-K is filed. Based on that evaluation, the CEO and CFO have concluded that the current disclosure controls and procedures are effective to ensure that information required to be disclosed in reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and include controls and procedures designed to ensure that information required to be disclosed by the Company in such reports is accumulated and communicated to management, including the CEO and CFO, as appropriate to allow timely decisions regarding required disclosures. Management, including our CEO (principal executive officer) and CFO (principal financial officer), believes the consolidated financial statements included in this Annual Report on Form 10-K fairly represent in all material respects our financial condition, results of operations and cash flows at and for the periods presented in accordance with U.S. GAAP. Management’s Annual Report on Internal Control Over Financial Reporting Management, under the supervision of our principal executive officer and principal financial officer, is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rule 13a-15(f) and 15d(f) under the Exchange Act). Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with GAAP, and includes those policies and procedures that: (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that receipts and expenditures of the Company are being made only in accordance with authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the financial statements. Because of the inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis. Our management conducted an assessment of the effectiveness of our internal control over financial reporting as of December 31, 2017. This assessment was based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control-Integrated Framework (2013 framework). Based on this assessment, management determined that our internal control over financial reporting was effective as of December 31, 2017. Our independent registered public accounting firm has issued a report on the effectiveness of our internal control over financial reporting which is below. Overview of Previously Reported Material Weaknesses In our Form 10-K for the fiscal year ended December 31, 2016, we disclosed that the Company did not maintain effective internal control over financial reporting and reported material weaknesses. Refer to Item 9A in our Annual Report on Form 10- K for the year ended December 31, 2016 for a description of these material weaknesses. To remediate the previously identified deficiencies, our leadership team, including the CEO and CFO, reaffirmed and reemphasized the importance of internal controls and an effective control environment. During 2017, the Company made significant changes and improvements to our internal controls over financial reporting that resulted in remediation of the previously reported material weaknesses. The Company’s remediation efforts included: restructuring our Executive Leadership Team, hiring experienced professionals into key positions, enhanced training for our personnel on our policies and internal control procedures and engaging external consultants to assist management in our efforts to strengthen our internal controls framework, enhancing or redesigning systems and related processes and increasing management oversight. At December 31, 2017, we completed the testing necessary to conclude that the material weaknesses previously identified have been remediated. Changes in Internal Control over Financial Reporting Other than those noted above, there were no changes in our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) during the last fiscal quarter that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited by Deloitte & Touche, LLP, an independent registered public accounting firm, as stated in their attestation report that follows. REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the shareholders and the Board of Directors of Exterran Corporation Houston, Texas Opinion on Internal Control over Financial Reporting We have audited the internal control over financial reporting of Exterran Corporation and subsidiaries (the “Company”) as of December 31, 2017, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated statements of operations, comprehensive income (loss), stockholders’ equity, cash flows, and the related notes and schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”) for the year ended December 31, 2017, of the Company and our report dated February 27, 2018, expressed an unqualified opinion on those consolidated financial statements and financial statement schedule. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and Limitations of Internal Control over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ DELOITTE & TOUCHE LLP Houston, Texas February 27, 2018 Item 9B.

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2018, expressed an unqualified opinion on the Company’s internal control over financial reporting. Basis for Opinion These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Emphasis of a Matter As described in Note 1, prior to November 3, 2015 the accompanying consolidated and combined financial statements were derived from the consolidated financial statements and accounting records of Archrock, Inc. The combined financial statements also include expense allocations for certain corporate functions historically provided by Archrock, Inc. These allocations may not be reflective of the actual expense which would have been incurred had the Company operated as a separate entity apart from Archrock, Inc. during the periods prior to November 3, 2015. /s/ DELOITTE & TOUCHE LLP Houston, Texas February 27, 2018 We have served as the Company’s auditor since 2014. EXTERRAN CORPORATION CONSOLIDATED BALANCE SHEETS (In thousands, except par value and share amounts) ASSETS Current assets: Cash and cash equivalents Restricted cash Accounts receivable, net of allowance of $5,388 and $5,383, respectively Inventory, net (Note 4) Costs and estimated earnings in excess of billings on uncompleted contracts (Note 5) Other current assets Current assets held for sale (Note 8) Current assets associated with discontinued operations (Note 3) Total current assets Property, plant and equipment, net (Note 6) Deferred income taxes (Note 16) Intangible and other assets, net (Note 7) Long-term assets held for sale (Note 8) Long-term assets associated with discontinued operations (Note 3) Total assets LIABILITIES AND STOCKHOLDERS’ EQUITY Current liabilities: Accounts payable, trade Accrued liabilities (Note 10) Deferred revenue Billings on uncompleted contracts in excess of costs and estimated earnings (Note 5) Current liabilities associated with discontinued operations (Note 3) Total current liabilities Long-term debt (Note 11) Deferred income taxes (Note 16) Long-term deferred revenue Other long-term liabilities Long-term liabilities associated with discontinued operations (Note 3) Total liabilities Commitments and contingencies (Note 22) Stockholders’ equity: Preferred stock, $0.01 par value per share;

In our contract operations business line, we own and operate natural gas compression equipment and crude oil and natural gas production and processing equipment on behalf of our customers outside of the U.S. In our aftermarket services business line, we sell parts and components and provide operations, maintenance, overhaul, upgrade, commissioning and reconfiguration services to customers outside of the U.S. who own their own compression, production, processing, treating and related equipment. In our product sales business line, we design, engineer, manufacture, install and sell natural gas compression packages as well as equipment used in the production, treating and processing of crude oil and natural gas to our customers throughout the world and for use in our contract operations business line. We also offer our customers, on either a contract operations basis or a sale basis, the engineering, design, project management, procurement and construction services necessary to incorporate our products into production, processing and compression facilities, which we refer to as integrated projects. Spin-off On November 3, 2015, Archrock, Inc. (named Exterran Holdings, Inc. prior to November 3, 2015) (“Archrock”) completed the spin-off (the “Spin-off”) of its international contract operations, international aftermarket services (the international contract operations and international aftermarket services businesses combined are referred to as the “international services businesses” and include such activities conducted outside of the U.S.) and global fabrication businesses into an independent, publicly traded company named Exterran Corporation. We refer to the global fabrication business previously operated by Archrock as our product sales business. To effect the Spin-off, on November 3, 2015, Archrock distributed, on a pro rata basis, all of our shares of common stock to its stockholders of record as of October 27, 2015 (the “Record Date”). Archrock shareholders received one share of Exterran Corporation common stock for every two shares of Archrock common stock held at the close of business on the Record Date. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, we transferred cash of $532.6 million to Archrock. Our Registration Statement on Form 10, as amended, was declared effective on October 21, 2015. On November 4, 2015, Exterran Corporation common stock began “regular-way” trading on the New York Stock Exchange under the stock symbol “EXTN.” Following the completion of the Spin-off, we and Archrock became and continue to be independent, publicly traded companies with separate boards of directors and management. Basis of Presentation The accompanying consolidated and combined financial statements of Exterran Corporation included herein have been prepared in accordance with generally accepted accounting principles in the U.S. (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (the “SEC”). All financial information presented for periods after the Spin-off represents our consolidated results of operations, financial position and cash flows (referred to as the “consolidated financial statements”) and all financial information for periods prior to the Spin-off represents our combined results of operations, financial position and cash flows (referred to as the “combined financial statements”). Accordingly: • Our consolidated and combined statements of operations, comprehensive income, cash flows and stockholders’ equity for the year ended December 31, 2015 consist of (i) the combined results of Archrock’s international services and product sales businesses for the period between January 1, 2015 and November 3, 2015 and (ii) the consolidated results of Exterran Corporation for periods subsequent to November 3, 2015. • Our consolidated balance sheets at December 31, 2017 and 2016 consist entirely of our consolidated balances. The combined financial statements were derived from the accounting records of Archrock and reflect the combined historical results of operations, financial position and cash flows of Archrock’s international services and product sales businesses. The combined financial statements were presented as if such businesses had been combined for periods prior to November 4, 2015. All intercompany transactions and accounts within these statements have been eliminated. Affiliate transactions between the international services and product sales businesses of Archrock and the other businesses of Archrock have been included in the combined financial statements, with the exception of product sales within our wholly owned subsidiary, Exterran Energy Solutions, L.P. (“EESLP”). Prior to the closing of the Spin-off, EESLP also had a fleet of compression units used to provide compression services in the U.S. services business of Archrock. Revenue has not been recognized in the combined statements of operations for the sale of compressor units by us that were used by EESLP to provide compression services to customers of the U.S. services business of Archrock. See Note 17 for further discussion on transactions with affiliates. The combined statements of operations for periods prior to the Spin-off include expense allocations for certain functions historically performed by Archrock and not allocated to its operating segments, including allocations of expenses related to executive oversight, accounting, treasury, tax, legal, human resources, procurement and information technology. See Note 17 for further discussion regarding the allocation of corporate expenses. Additionally, third party debt of Archrock, other than debt attributable to capital leases, was not allocated to us for any of the periods prior to the Spin-off as we were not the legal obligor of the debt and Archrock’s borrowings were not directly attributable to our business. We refer to the consolidated and combined financial statements collectively as “financial statements,” and individually as “balance sheets,” “statements of operations,” “statements of comprehensive income (loss),” “statements of stockholders’ equity” and “statements of cash flows” herein. Note 2. Significant Accounting Policies Use of Estimates in the Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of assets, liabilities, revenue and expenses, as well as the disclosures of contingent assets and liabilities. Because of the inherent uncertainties in this process, actual future results could differ from those expected at the reporting date. Significant estimates are required for contracts within our products sales segment that are accounted for under the percentage-of-completed method. As of December 31, 2017, we have estimated costs-to-complete on all of our ongoing contracts. However, it is possible that current estimates could change due to unforeseen events, which could result in adjustments to overall contract costs. Variations from estimated contract performance could result in material adjustments to operating results. Management believes that the estimates and assumptions used are reasonable. Cash and Cash Equivalents We consider all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Restricted Cash Restricted cash as of December 31, 2017 and 2016 consists of cash that contractually is not available for immediate use. Restricted cash is presented separately from cash and cash equivalents in our balance sheets and statements of cash flows. Revenue Recognition Contract operations revenue is recognized when earned, which generally occurs monthly when service is provided under our customer contracts. Aftermarket services revenue is recognized as products are delivered and title is transferred or services are performed for the customer. Product sales revenue is recognized using the percentage-of-completion method when the applicable criteria are met. We estimate percentage-of-completion for compressor and production and processing equipment product sales on a direct labor hour to total labor hour basis. The duration of these projects is typically between three and 24 months. Product sales revenue is recognized using the completed contract method when the applicable criteria of the percentage-of-completion method are not met. Product sales revenue under the completed contract method is recognized upon either delivery to the customer or achievement of substantial completion in accordance with the specifications within the underlying contract, which generally occurs when all significant attributes and components of the product are completed. Prior to the Spin-off, product sales revenue from affiliates was recognized using the completed contract method as the equipment was not guaranteed to be sold to the affiliate until the entities entered into a bill of sale for such equipment which occurred at the completion of the manufacturing process. Subsequent to November 3, 2015, sales to Archrock and Archrock Partners, L.P. (named Exterran Partners, L.P. prior to November 3, 2015) (“Archrock Partners”) are considered sales to third parties. Product sales revenue from a claim is recognized to the extent that costs related to the claim have been incurred, when collection is probable and can be reliably estimated. We estimate the future costs and gross margin on uncompleted contracts related to our product sales contracts. If we determine that a contract will result in a loss, we record a provision for the entire amount of the estimated loss in the period in which the loss is identified. Concentrations of Credit Risk Financial instruments that potentially subject us to concentrations of credit risk consist of cash and cash equivalents and accounts receivable. We believe that the credit risk in temporary cash investments is limited because our cash is held in accounts with multiple financial institutions. We record trade accounts receivable at the amount we invoice our customers, net of allowance for doubtful accounts. Trade accounts receivable are due from companies of varying sizes engaged principally in oil and natural gas activities throughout the world. We review the financial condition of customers prior to extending credit and generally do not obtain collateral for trade receivables. Payment terms are on a short-term basis and in accordance with industry practice. We consider this credit risk to be limited due to these companies’ financial resources, the nature of products and services we provide and the terms of our contract operations customer service agreements. We maintain allowances for doubtful accounts for estimated losses resulting from our customers’ inability to make required payments. The determination of the collectibility of amounts due from our customers requires us to use estimates and make judgments regarding future events and trends, including monitoring our customers’ payment history and current creditworthiness to determine that collectibility is reasonably assured, as well as consideration of the overall business climate in which our customers operate. Inherently, these uncertainties require us to make judgments and estimates regarding our customers’ ability to pay amounts due to us in order to determine the appropriate amount of valuation allowances required for doubtful accounts. We review the adequacy of our allowance for doubtful accounts quarterly. We determine the allowance needed based on historical write-off experience and by evaluating significant balances aged greater than 90 days individually for collectibility. Account balances are charged off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote. During the years ended December 31, 2017, 2016 and 2015, we recorded bad debt expense of $0.9 million, $3.0 million and $3.3 million, respectively. Inventory Inventory consists of parts used for manufacturing or maintenance of natural gas compression equipment and facilities, parts for processing and production equipment, new compression units and production equipment that are held for sale. Inventory is stated at the lower of cost and net realizable value using the average cost method. A reserve is recorded against inventory balances for estimated obsolescence and slow moving items based on specific identification and historical experience. Property, Plant and Equipment Property, plant and equipment is recorded at cost and depreciated using the straight-line method over their estimated useful lives as follows: Compression equipment, facilities and other fleet assets Buildings Transportation, shop equipment and other 3 to 23 years (1) 20 to 35 years 3 to 10 years (1) In the fourth quarter of 2017, we evaluated the estimated useful lives and salvage values of our property, plant and equipment. As a result of this evaluation, we changed the useful lives and salvage values for our compression equipment from a maximum useful life of 30 years to 23 years and a maximum salvage value of 20% to 15% based on expected future use. During the year ended December 31, 2017, we recorded a $1.2 million increase in depreciation expense as a result of these changes in useful lives and salvage values. Installation costs capitalized on contract operations projects are generally depreciated over the life of the underlying contract. Major improvements that extend the useful life of an asset are capitalized. Repairs and maintenance are expensed as incurred. When property, plant and equipment is sold, or otherwise disposed of, the gain or loss is recorded in other (income) expense, net. Interest is capitalized during the construction period on equipment and facilities that are constructed for use in our operations. The capitalized interest is included as part of the cost of the asset to which it relates and is amortized over the asset’s estimated useful life. Computer Software Certain costs related to the development or purchase of internal-use software are capitalized and amortized over the estimated useful life of the software, which ranges from three to five years. Costs related to the preliminary project stage and the post- implementation/operation stage of an internal-use computer software development project are expensed as incurred. Capitalized software costs are included in property, plant and equipment, net, in our balance sheets. Long-Lived Assets We review long-lived assets such as property, plant and equipment and identifiable intangibles subject to amortization for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable. An impairment loss exists when estimated undiscounted cash flows expected to result from the use of the asset and its eventual disposition are less than its carrying amount. When necessary, an impairment loss is recognized and represents the excess of the asset’s carrying value as compared to its estimated fair value and is charged to the period in which the impairment occurred. Identifiable intangibles are amortized over the assets’ estimated useful lives. Deferred Revenue Deferred revenue is primarily comprised of upfront billings on contract operations projects, milestone billings related to projects where revenue is recognized on the completed contract method and billings related to projects that have not begun where revenue is recognized on the percentage-of-completion method. Upfront payments received from customers on contract operations projects are generally deferred and amortized over the life of the underlying contract. Other (Income) Expense, Net Other (income) expense, net, is primarily comprised of gains and losses from the remeasurement of our international subsidiaries’ net assets exposed to changes in foreign currency rates, short-term investments and the sale of used assets. Income Taxes Our operations are subject to U.S. federal, state and local and foreign income taxes. We and our subsidiaries file consolidated and separate income tax returns in the U.S. federal jurisdiction and in numerous state and foreign jurisdictions. In addition, certain of our operations were historically included in Archrock’s consolidated income tax returns in the U.S. federal and state jurisdictions. Our tax provision for periods prior to the Spin-off was determined on a separate return, stand-alone basis. Prior to the Spin-off, differences between the separate return method utilized and Archrock’s U.S. income tax returns and cash flows attributable to income taxes for our U.S. operations were recognized as distributions to, or contributions from, parent within parent equity. We account for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. We record net deferred tax assets to the extent we believe these assets will more-likely-than-not be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax-planning strategies and results of recent operations. In the event we were to determine that we would be able to realize our deferred income tax assets in the future in excess of their net recorded amount, we would make an adjustment to the deferred tax asset valuation allowance, which would reduce the provision for income taxes. We record uncertain tax positions in accordance with the accounting standard on income taxes under a two-step process whereby (1) we determine whether it is more-likely-than-not that the tax positions will be sustained based on the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is greater than 50 percent likely to be realized upon ultimate settlement with the related tax authority. On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act (the “Tax Reform Act”). We recognize the impact of tax legislation in the period in which the law is enacted. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Reform Act. Consistent with that guidance, we recognized provisional amounts based upon our interpretation of the tax laws and estimates which require significant judgments. The actual impact of these tax laws may differ from these provisional amounts, possibly materially, due to, among other things, additional analysis, changes in our interpretations and assumptions, additional guidance that may be issued by the government and actions we may take as a result of these enacted tax laws. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to tax expense. Foreign Currency Translation The financial statements of our subsidiaries outside the U.S., except those for which we have determined that the U.S. dollar is the functional currency, are measured using the local currency as the functional currency. Assets and liabilities of these subsidiaries are translated at the exchange rates in effect at the balance sheet date. Income and expense items are translated at average monthly exchange rates. The resulting gains and losses from the translation of accounts into U.S. dollars are included in accumulated other comprehensive income in our balance sheets. For all subsidiaries, gains and losses from remeasuring foreign currency accounts into the functional currency are included in other (income) expense, net, in our statements of operations. We recorded foreign currency losses of $0.7 million, foreign currency gains of $6.5 million and foreign currency losses of $35.8 million during the years ended December 31, 2017, 2016 and 2015, respectively. Included in our foreign currency gains and losses were non-cash gains of $0.5 million, $9.3 million and non-cash losses of $30.1 million during the years ended December 31, 2017, 2016 and 2015, respectively, from foreign currency exchange rate changes recorded on intercompany obligations. Of the foreign currency losses recognized during the year ended December 31, 2015, $29.7 million was attributable to our Brazilian subsidiary’s U.S. dollar denominated intercompany obligations and were the result of a currency devaluation in Brazil and increases in our Brazilian subsidiary’s intercompany payables during 2015. During the second quarter of 2016, we entered into forward currency exchange contracts with a total notional value of $11.3 million that expired over varying dates through October 31, 2016. We entered into these foreign currency derivatives to offset exchange rate exposure related to intercompany loans to a subsidiary whose functional currency is the Brazilian Real. We did not designate these forward currency exchange contracts as hedge transactions. Changes in fair value and gains and losses on settlement on these forward currency exchange contracts were recognized in other (income) expense, net, in our statements of operations. During the year ended December 31, 2016, we recognized a loss of $0.7 million on forward currency exchange contracts. All of the forward currency exchange contracts that we entered into were settled prior to December 31, 2016. Argentina’s regulations have at times restricted foreign exchange, including exchanging Argentine pesos for U.S. dollars, and during these periods we were unable to freely repatriate cash generated in Argentina to fund our other operations. In late 2015, some of the currency restrictions were lifted and we have been able to exchange Argentine pesos for U.S. dollars at market rates. Prior to the currency restrictions being lifted in Argentina in late 2015, we used Argentine pesos to purchase certain short- term investments in Argentine government issued U.S. dollar denominated bonds. The effective peso to U.S. dollar exchange rate embedded in the purchase price of these bonds resulted in our recognition of a loss during the year ended December 31, 2015 of $4.9 million, which is included in other (income) expense, net, in our statements of operations. Recent Accounting Pronouncements We consider the applicability and impact of all Accounting Standard Updates (“ASUs”). ASUs not listed below were assessed and determined to be either not applicable or are expected to have minimal impact on our consolidated financial position or results of operations. Recently Adopted Accounting Pronouncements In July 2015, the Financial Accounting Standards Board (“FASB”) issued ASU 2015-11, Simplifying the Measurement of Inventory, which requires an entity to measure inventory at the lower of cost and net realizable value. Net realizable value is defined as the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. On January 1, 2017, we adopted this update on a prospective basis. The adoption of this update did not have a material impact on our financial statements. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718). The update covers such areas as the recognition of excess tax benefits and deficiencies, the classification of those excess tax benefits on the statement of cash flows, an accounting policy election for forfeitures, the amount an employer can withhold to cover income taxes and still qualify for equity classification and the classification of those taxes paid on the statement of cash flows. On January 1, 2017, we adopted this update. Upon adoption, we elected to account for forfeitures as they occur rather than applying an estimated forfeiture rate, which resulted in a cumulative-effect adjustment to accumulated deficit and additional paid-in capital of $0.1 million under the modified retrospective transition method. Additionally, as a result of this adoption, cash flows related to excess tax benefits are now presented as operating activities within the statements of cash flows. The impact of this retrospective adoption was immaterial to the results of the prior year periods. Recently Issued Accounting Pronouncements Not Yet Adopted In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606). The update outlines a single comprehensive model for companies to use in accounting for revenue arising from contracts with customers and supersedes the most current revenue recognition guidance, including industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue when promised goods or services are transferred to customers in an amount that reflects the consideration to which the entity expects to be entitled for those goods or services. The update also requires disclosures enabling users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Furthermore, as part of Topic 606, the FASB introduced ASC 340-40 Other Assets and Deferred Costs, which provides guidance on the capitalization of contract related costs that are not within the scope of other authoritative literature. The update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period. Companies may use either a full retrospective or a modified retrospective approach to adopt the updates. We intend to adopt the new guidance on January 1, 2018 using the modified retrospective approach. In preparation for our adoption of the new standard, we have evaluated representative samples of contracts and other forms of agreements with our customers based upon the five-step model specified by the new guidance. We have completed a preliminary assessment of the potential impact the implementation of this new guidance may have on our financial statements. Although our preliminary assessment may change based upon completion of our evaluation, the following summarizes the more significant impacts expected from the adoption of the new standard: • Revenue from installation services within our product sales segment is currently recognized using the completed contract method. Under the new standard, revenue from such services is expected to be recognized over time. • Revenue from overhaul and reconfiguration services within our aftermarket services segment is currently recognized • at a point in time. Under the new standard, revenue from such services is expected to be recognized over time. Sales commissions associated with long-term service contracts are currently expensed in the period the payment is due to the sales agent. Under the new standard, those costs are expected to be capitalized at the contract inception and amortized over the contract term. • Certain costs to fulfill a contract that are currently being expensed as incurred are expected to be capitalized as a contract related costs and amortized over the contract term. Additionally, the new guidance will require us to enhance our disclosures to provide additional information relating to disaggregated revenue, contract assets and liabilities and remaining performance obligations. As stated above, we have elected to use the modified retrospective approach and the impact of the adoption of Topic 606 that will be recorded as an adjustment to our January 1, 2018 beginning accumulated deficit balance is tentatively estimated to be less than $10.0 million. We are currently evaluating potential changes to our information systems, processes and internal controls to meet the new standard’s reporting and disclosure requirements. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The update requires lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statements of operations. The update also requires certain qualitative and quantitative disclosures about the amount, timing and uncertainty of cash flows arising from leases. Lessor accounting will be similar to the current model except for changes made to align with certain changes to the lessee model and the new revenue recognition standard. Existing sale-leaseback guidance will be replaced with a new model applicable to both lessees and lessors. This update is effective for annual and interim periods beginning after December 15, 2018, with early adoption permitted. Adoption will require a modified retrospective approach beginning with the earliest period presented. We are currently evaluating the potential impact of the update on our financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326). The update changes the impairment model for most financial assets and certain other instruments, including trade and other receivables, held-to- maturity debt securities and loans, and requires entities to use a new forward-looking expected loss model that will result in the earlier recognition of allowance for losses. This update is effective for annual and interim periods beginning after December 15, 2019, with early adoption permitted. Adoption will require a modified retrospective approach beginning with the earliest period presented. We are currently evaluating the potential impact of the update on our financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). The update addresses eight specific cash flow issues and is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. This update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period. This update will require adoption on a retrospective basis unless it is impracticable to apply, in which case it would be required to apply the amendments prospectively as of the earliest date practicable. We do not expect the adoption of this update to be material to our financial statements. In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory. The update requires a reporting entity to recognize the tax expense from intra-entity asset transfers of assets other than inventory in the selling entity’s tax jurisdiction when the transfer occurs, even though the pre-tax effects of that transaction are eliminated in consolidation. Any deferred tax asset that arises in the buying entity’s jurisdiction would also be recognized at the time of the transfer. This update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period. Adoption will require a modified retrospective approach beginning with the earliest period presented. While we are still evaluating the impact of the new guidance, we currently do not expect the adoption of this update to be material to our financial statements. In November 2016, the FASB issued ASU 2016-18, Restricted Cash. The guidance requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. This update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period, using a retrospective transition method to each period presented. This update will result in the inclusion of our restricted cash balances with cash and cash equivalents to reflect total cash in our statements of cash flows. We do not expect the adoption of this update to be material to our financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation (Topic 718). This update provides guidance that clarifies that changes to the terms or conditions of a share-based payment award should be accounted for as modifications. This update will be effective for reporting periods beginning after December 15, 2017, including interim periods within the reporting period, using a prospective method to an award modified on or after the adoption date. We do not expect the adoption of this update to be material to our financial statements. Note 3. Discontinued Operations In June 2009, Petroleos de Venezuela S.A. (“PDVSA”) commenced taking possession of our assets and operations in a number of our locations in Venezuela, and by the end of the second quarter of 2009, PDVSA had assumed control over substantially all of our assets and operations in Venezuela. The expropriation of our business in Venezuela meets the criteria established for recognition as discontinued operations under GAAP. Therefore, our Venezuelan contract operations business is reflected as discontinued operations in our financial statements. In March 2010, our Spanish subsidiary filed a request for the institution of an arbitration proceeding against Venezuela with the International Centre for Settlement of Investment Disputes (“ICSID”) related to the seized assets and investments under the agreement between Spain and Venezuela for the Reciprocal Promotion and Protection of Investments and under Venezuelan law. The arbitration hearing occurred in July 2012. In August 2012, our Venezuelan subsidiary sold its previously nationalized assets to PDVSA Gas, S.A. (“PDVSA Gas”) for a purchase price of approximately $441.7 million. We received an initial payment of $176.7 million in cash at closing, of which we remitted $50.0 million to repay the amount we collected in January 2010 under the terms of an insurance policy we maintained for the risk of expropriation. We received installment payments, including an annual charge, totaling $19.7 million, $38.8 million and $56.6 million during the years ended December 31, 2017, 2016 and 2015, respectively. As of December 31, 2017, the remaining principal amount due to us was approximately $17 million. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize payments received in the future as income from discontinued operations in the periods such payments are received. The proceeds from the sale of the assets are not subject to Venezuelan national taxes due to an exemption allowed under the Venezuelan Reserve Law applicable to expropriation settlements. In addition, and in connection with the sale, we and the Venezuelan government agreed to waive rights to assert certain claims against each other. In connection with the sale of these assets, we have agreed to suspend the arbitration proceeding previously filed by our Spanish subsidiary against Venezuela pending payment in full by PDVSA Gas of the purchase price for these nationalized assets. In accordance with the separation and distribution agreement from the Spin-off, a subsidiary of Archrock has the right to receive payments from EESLP, based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our previously nationalized assets promptly after such amounts are collected by our subsidiaries. Pursuant to the separation and distribution agreement, we transferred cash of $19.7 million and $38.8 million to Archrock during the years ended December 31, 2017 and 2016, respectively. The transfers of cash were recognized as reductions to additional paid-in capital in our financial statements. See Note 22 for further discussion related to our contingent liability to Archrock. In the first quarter of 2016, we began executing a plan to exit certain Belleli businesses to focus on our core businesses. Specifically, we began marketing for sale the Belleli CPE business comprised of engineering, procurement and manufacturing services related to the manufacture of critical process equipment for refinery and petrochemical facilities (referred to as “Belleli CPE” or the “Belleli CPE business” herein). Belleli CPE met the held for sale criteria and is reflected as discontinued operations in our financial statements for all periods presented. In August 2016, we completed the sale of our Belleli CPE business to Tosto S.r.l. for cash proceeds of $5.5 million. Belleli CPE was previously included in our product sales segment. In conjunction with the planned disposition of Belleli CPE, we recorded impairments of long-lived assets and current assets that totaled $68.8 million during the year ended December 31, 2016. The impairment charges are reflected in income (loss) from discontinued operations, net of tax. In addition, in the first quarter of 2016, we began executing our exit of the Belleli EPC business that has historically been comprised of engineering, procurement and construction for the manufacture of tanks for tank farms and the manufacture of evaporators and brine heaters for desalination plants in the Middle East (referred to as “Belleli EPC” or the “Belleli EPC business” herein) by ceasing the bookings of new orders. As of the fourth quarter of 2017, we have substantially exited our Belleli EPC business and, in accordance with GAAP, it is reflected as discontinued operations in our financial statements for all periods presented. Although we have reached mechanical completion on all remaining Belleli EPC contracts, we are still subject to risks and uncertainties potentially resulting from warranty obligations, customer or vendors claims against us, settlement of claims against customers, completion of demobilization activities and litigation developments. The facility previously utilized to manufacture products for our Belleli EPC business has been repurposed to manufacture product sales equipment. As such, certain personnel, buildings, equipment and other assets that were previously related to the Belleli EPC business will remain as part of our continuing operations. As a result, activities associated with our ongoing operations at our repurposed facility are included in continuing operations.

Assets Held for Sale As part of our continual strategic review and optimization of our business structure and the service solutions we offer to our customers, we identified certain assets within our products sales business that we expect to sell within the next twelve months. In the fourth quarter of 2017, we classified $20.5 million of current and long-term assets primarily related to inventory and property, plant and equipment, net, as assets held for sale in our balance sheet. We also determined that certain other assets within our product sales business were assessed to have no future benefit to our ongoing operations. In conjunction with the planned disposition and assessment of certain other assets, we recorded an impairment of long-lived assets that totaled $5.1 million to write-down these assets to their approximate fair values. The impairment charges are reflected in long-lived asset impairment in our statements of operations. Note 9. Investments in Non-Consolidated Affiliates Investments in affiliates that are not controlled by us where we have the ability to exercise significant influence over the operations are accounted for using the equity method. We own a 30.0% interest in WilPro Energy Services (PIGAP II) Limited and 33.3% interest in WilPro Energy Services (El Furrial) Limited, which are joint ventures that provided natural gas compression and injection services in Venezuela. In May 2009, PDVSA assumed control over the assets of our Venezuelan joint ventures and transitioned the operations, including the hiring of their employees, to PDVSA. In March 2011, our Venezuelan joint ventures, together with the Netherlands’ parent company of our joint venture partners, filed a request for the institution of an arbitration proceeding against Venezuela with ICSID related to the seized assets and investments. In March 2012, our Venezuelan joint ventures sold their assets to PDVSA Gas. We received an initial payment of $37.6 million in March 2012, and received installment payments, including an annual charge, totaling $10.4 million and $15.2 million during the years ended December 31, 2016 and 2015, respectively. As of December 31, 2017, the remaining principal amount due to us was approximately $4 million. We have not recognized amounts payable to us by PDVSA Gas as a receivable and will therefore recognize payments received in the future as equity in income of non-consolidated affiliates in our statements of operations in the periods such payments are received. In connection with the sale of our Venezuelan joint ventures’ assets, the joint ventures and our joint venture partners have agreed to suspend their previously filed arbitration proceeding against Venezuela pending payment in full by PDVSA Gas of the purchase price for the assets. In accordance with the separation and distribution agreement, a subsidiary of Archrock has the right to receive payments from EESLP based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries. Pursuant to the separation and distribution agreement, we transferred cash of $10.4 million to Archrock during the year ended December 31, 2016. The transfer of cash was recognized as a reduction to additional paid-in capital in our financial statements. See Note 22 for further discussion related to our contingent liability to Archrock. Note 10. Accrued Liabilities Accrued liabilities consisted of the following (in thousands): Accrued salaries and other benefits Accrued income and other taxes Accrued warranty expense Accrued interest Accrued other liabilities Accrued liabilities December 31, 2017 2016 $ 53,492 $ 26,503 3,190 6,000 25,151 41,399 41,329 2,912 2,889 30,926 $ 114,336 $ 119,455 Our warranty expense was $1.9 million, $1.6 million and $3.6 million during the years ended December 31, 2017, 2016 and 2015, respectively. Note 11. Long-Term Debt Long-term debt consisted of the following (in thousands): Revolving credit facility due November 2020 Term loan facility due November 2017 8.125% senior notes due May 2025 Other, interest at various rates, collateralized by equipment and other assets Unamortized deferred financing costs of 8.125% senior notes Unamortized deferred financing costs of term loan facility Long-term debt Revolving Credit Facility and Term Loan December 31, 2017 2016 $ — $ — 118,000 232,750 375,000 722 (7,250) — $ 368,472 $ — 583 — (2,363) 348,970 On July 10, 2015, we and our wholly owned subsidiary, EESLP, entered into a $750.0 million credit agreement (the “Credit Agreement”) with Wells Fargo, as the administrative agent, and various financial institutions as lenders. On October 5, 2015, the parties amended and restated the Credit Agreement to provide for a $925.0 million credit facility, consisting of a $680.0 million revolving credit facility and a $245.0 million term loan facility (collectively, the “Credit Facility”). The Credit Facility became available to us on November 3, 2015 (referred to as the “Initial Availability Date”). On November 3, 2015, EESLP incurred approximately $300.0 million of indebtedness under the revolving credit facility and $245.0 million of indebtedness under the term loan facility. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, EESLP transferred $532.6 million of net proceeds from borrowings under the Credit Facility to Archrock to allow it to repay a portion of its indebtedness in connection with the Spin-off. In November 2016, we repaid $12.3 million of borrowings outstanding under the term loan facility. In April 2017, we paid the remaining principal amount of $232.8 million due under the term loan facility with proceeds from the 2017 Notes (as defined below) issuance. As a result of the repayment of the term loan facility, we expensed $1.7 million of unamortized deferred financing costs during the year ended December 31, 2017, which is reflected in interest expense in our statements of operations. As of December 31, 2017, we had $39.7 million in outstanding letters of credit under our revolving credit facility and, taking into account guarantees through letters of credit, we had undrawn capacity of $640.3 million under our revolving credit facility. Our Credit Agreement limits our Total Debt to EBITDA ratio (as defined in the Credit Agreement) on the last day of the fiscal quarter to no greater than 4.50 to 1.0. As a result of this limitation, $585.2 million of the $640.3 million of undrawn capacity under our revolving credit facility was available for additional borrowings as of December 31, 2017. Revolving borrowings under the Credit Facility bear interest at a rate equal to, at our option, either the Base Rate or LIBOR (or EURIBOR, in the case of Euro-denominated borrowings) plus the applicable margin. The applicable margin for revolving borrowings varies (i) in the case of LIBOR loans, from 1.50% to 2.75% and (ii) in the case of Base Rate loans, from 0.50% to 1.75%, and will be determined based on our total leverage ratio pricing grid. “Base Rate” means the highest of the prime rate, the federal funds effective rate plus 0.50% and one-month LIBOR plus 1.00%. Prior to the repayment of the term loan facility, the applicable margin for borrowings under the revolving credit facility increased by 1.00% the first anniversary of the Initial Availability Date and by 1.50% following the first anniversary of the Initial Availability Date. Term loan borrowings under the Credit Facility incurred interest at a rate equal to, at our option, either (1) the Base Rate plus 4.75%, or (2) the greater of LIBOR or 1.00%, plus 5.75%. The weighted average annual interest rate on outstanding borrowings under the revolving credit facility at December 31, 2016 was 5.0%. The annual interest rate on the outstanding balance of the term loan facility at December 31, 2016 was 6.8%. We guarantee EESLP’s obligations under the revolving credit facility. In addition, EESLP’s obligations under the revolving credit facility are secured by (1) substantially all of our assets and the assets of EESLP and our Significant Domestic Subsidiaries (as defined in the Credit Agreement), including certain real property, and (2) all of the equity interests of our U.S. restricted subsidiaries (other than certain excluded subsidiaries) (as defined in the Credit Agreement) and 65% of the voting equity interests in certain of our first-tier foreign subsidiaries. 8.125% Senior Notes Due May 2025 In April 2017, our 100% owned subsidiaries EESLP and EES Finance Corp. issued $375.0 million aggregate principal amount of 8.125% senior unsecured notes due 2025 (the “2017 Notes”). The 2017 Notes are guaranteed by us on a senior unsecured basis. The net proceeds of $367.1 million from the 2017 Notes issuance were used to repay all of the borrowings outstanding under the term loan facility and revolving credit facility and for general corporate purposes. Additionally, pursuant to the separation and distribution agreement from the Spin-off, EESLP used proceeds from the issuance of the 2017 Notes to pay a subsidiary of Archrock $25.0 million in satisfaction of EESLP’s obligation to pay that sum following the occurrence of a qualified capital raise. The transfer of cash to Archrock’s subsidiary was recognized as a reduction to additional paid-in capital in the second quarter of 2017. The 2017 Notes have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and unless so registered, may not be offered or sold in the U.S. except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws. We offered and issued the 2017 Notes only to qualified institutional buyers pursuant to Rule 144A under the Securities Act and to persons outside the U.S. pursuant to Regulation S. Pursuant to a registration rights agreement, we are required to register the 2017 Notes no later than 400 days after April 4, 2017. Prior to May 1, 2020, we may redeem all or a portion of the 2017 Notes at a redemption price equal to the sum of (i) the principal amount thereof, and (ii) a make-whole premium at the redemption date, plus accrued and unpaid interest, if any, to the redemption date. In addition, we may redeem up to 35% of the aggregate principal amount of the 2017 Notes prior to May 1, 2020 with the net proceeds of one or more equity offerings at a redemption price of 108.125% of the principal amount of the 2017 Notes, plus any accrued and unpaid interest to the date of redemption, if at least 65% of the aggregate principal amount of the 2017 Notes issued under the indenture remains outstanding after such redemption and the redemption occurs within 180 days of the date of the closing of such equity offering. On or after May 1, 2020, we may redeem all or a portion of the 2017 Notes at redemption prices (expressed as percentages of principal amount) equal to 106.094% for the twelve-month period beginning on May 1, 2020, 104.063% for the twelve-month period beginning on May 1, 2021, 102.031% for the twelve-month period beginning on May 1, 2022 and 100.000% for the twelve-month period beginning on May 1, 2023 and at any time thereafter, plus accrued and unpaid interest, if any, to the applicable redemption date of the 2017 Notes. Unamortized Debt Financing Costs During the year ended December 31, 2017, we incurred transaction costs of $7.9 million related to the issuance of the 2017 Notes. These costs are presented as a direct deduction from the carrying value of the 2017 Notes and are being amortized over the term of the 2017 Notes. Amortization of deferred financing costs relating to the 2017 Notes totaled $0.7 million during the year ended December 31, 2017 and was recorded to interest expense in our statements of operations. Amortization of deferred financing costs relating to the term loan facility totaled $0.7 million, $2.9 million and $0.4 million during the years ended December 31, 2017, 2016 and 2015, respectively, and was recorded to interest expense in our statements of operations. During the year ended December 31, 2016, we incurred transaction costs of approximately $0.8 million related to our revolving credit facility. Debt issuance costs relating to our revolving credit facility are included in intangible and other assets, net, and are being amortized over the term of the facility. See Note 7 for further discussion regarding the amortization of deferred financing costs related to our revolving credit facility. Debt Compliance The Credit Agreement contains various covenants with which we, EESLP and our respective restricted subsidiaries must comply including, but not limited to, limitations on the incurrence of indebtedness, investments, liens on assets, repurchasing equity, distributions, transactions with affiliates, mergers, consolidations, dispositions of assets and other provisions customary in similar types of agreements. We are required to maintain, on a consolidated basis, a minimum interest coverage ratio (as defined in the Credit Agreement) of 2.25 to 1.00; a maximum total leverage ratio (as defined in the Credit Agreement) of 4.50 to 1.00; and a maximum senior secured leverage ratio (as defined in the Credit Agreement) of 2.75 to 1.00. As of December 31, 2017, we were in compliance with all financial covenants under the Credit Agreement. Long-Term Debt Maturity Schedule Contractual maturities of long-term debt (excluding interest to be accrued thereon) at December 31, 2017 are as follows (in thousands): 2018 2019 2020 2021 2022 Thereafter Total debt (1) December 31, 2017 — 449 273 — — 375,000 375,722 $ $ (1) This amount includes the full face value of the 2017 Notes and does not include unamortized debt financing costs of $7.3 million as of December 31, 2017. Note 12. Fair Value Measurements The accounting standard for fair value measurements and disclosures establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value into the following three broad categories: • • • Level 1 — Quoted unadjusted prices for identical instruments in active markets to which we have access at the date of measurement. Level 2 — Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Level 2 inputs are those in markets for which there are few transactions, the prices are not current, little public information exists or prices vary substantially over time or among brokered market makers. Level 3 — Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. Unobservable inputs are those inputs that reflect our own assumptions regarding how market participants would price the asset or liability based on the best available information. The following table presents our assets and liabilities measured at fair value on a nonrecurring basis during the years ended December 31, 2017 and 2016, with pricing levels as of the date of valuation (in thousands): Impaired long-lived assets (1) Impaired assets—assets held for sale (2) Impaired assets—discontinued operations (3) Note receivable from the sale of a plant (4) Liability to exit the use of a corporate operating lease—restructuring and other charges (5) Year Ended December 31, 2017 Year Ended December 31, 2016 (Level 1) (Level 2) (Level 3) (Level 1) (Level 2) (Level 3) $ — $ — $ 403 $ — $ — $ 3,109 — — — — — — — — 20,493 — — — — — — — — — — — — 13,859 7,037 3,580 (1) (2) (3) (4) (5) Our estimate of the fair value of the impaired long-lived assets during the years ended December 31, 2017 and 2016 was primarily based on either the expected net sale proceeds compared to other fleet units we sold and/or a review of other units offered for sale by third parties during that time or the estimated component value of the equipment we planned to use at that time. Our estimate of the fair value of the impaired assets held for sale during the year ended December 31, 2017 was based on the expected proceeds from the sale of the assets. Our estimate of the fair value of the impaired assets of Belleli CPE, which were classified as discontinued operations during the year ended December 31, 2016, was based on the proceeds received from the sale of Belleli CPE, net of selling costs. Our estimate of the fair value of the note receivable, including annual payments, from the sale of our plant in Argentina during the year ended December 31, 2016 was discounted based on a settlement period of 2.6 years and a discount rate of 5%. The fair value of our liability to exit the use of a corporate operating lease relating restructuring activities during the second quarter of 2016 was estimated based on an incremental borrowing rate of 3% and remaining lease payments, net of estimated sublease rentals, through February 2018. Fair Value of Debt The fair value of the 2017 Notes was estimated based on model derived calculations using market yields observed in active markets, which are Level 2 inputs. As of December 31, 2017, the carrying amount of the 2017 Notes, excluding unamortized deferred financing costs, of $375.0 million was estimated to have a fair value of $404.0 million. Due to the variable rate nature of our revolving credit facility and term loan facility, the carrying values as of December 31, 2016 approximated their fair values as the rates were comparable to then-current market rates at which debt with similar terms could have been obtained. Other Our financial instruments also consist of cash, restricted cash, receivables and payables. As of December 31, 2017 and 2016, the estimated fair values of our cash, restricted cash, receivables and payables approximated their carrying amounts as reflected in our balance sheets due to the short-term nature of these financial instruments. Note 13. Long-Lived Asset Impairment We review long-lived assets, including property, plant and equipment and identifiable intangibles that are being amortized, for impairment whenever events or changes in circumstances, including the removal of compressor units from our active fleet, indicate that the carrying amount of an asset may not be recoverable. We regularly review the future deployment of our idle compression assets used in our contract operations segment for units that are not the type, configuration, condition, make or model that are cost efficient to maintain and operate. During the years ended December 31, 2017, 2016 and 2015, we determined that one idle compressor unit, 62 idle compressor units and 93 idle compressor units, respectively, would be retired from the active fleet. The retirement of these units from the active fleet triggered a review of these assets for impairment. As a result, we recorded asset impairments of $0.6 million, $12.7 million and $19.4 million during the years ended December 31, 2017, 2016 and 2015, respectively, to reduce the book value of each unit to its estimated fair value. The fair value of each unit was estimated based on either the expected net sale proceeds compared to other fleet units we sold and/or a review of other units offered for sale by third parties during that time or the estimated component value of the equipment on each compressor unit that we planned to use at that time. In the fourth quarter of 2017, we classified certain assets within our product sales business that we expect to sell within the next twelve months as assets held for sale in our balance sheet. We also determined that certain other assets within our product sales business were assessed to have no future benefit to our ongoing operations. In conjunction with the planned disposition and assessment of certain other assets, we recorded an impairment of long-lived assets that totaled $5.1 million to write-down these assets to their approximate fair values. During the year ended December 31, 2016, we evaluated other assets for impairment and recorded long-lived asset impairments of $1.7 million on these assets. During the first quarter of 2015, we evaluated a long-term note receivable from the purchaser of our Canadian Operations for impairment. This review was triggered by an offer from the purchaser of our Canadian Operations to prepay the note receivable at a discount to its then current book value. The fair value of the note receivable as of March 31, 2015 was based on the amount offered by the purchaser of our Canadian Operations to prepay the note receivable. The difference between the book value of the note receivable at March 31, 2015 and its fair value resulted in the recording of an impairment of long-lived assets of $1.4 million. In April 2015, we accepted the offer to early settle this note receivable. Note 14. Restatement Related Charges During the first quarter of 2016, our senior management identified errors relating to the application of percentage-of- completion accounting principles to specific Belleli EPC product sales projects. As a result, the Audit Committee of the Company’s Board of Directors initiated an internal investigation, including the use of services of a forensic accounting firm. Management also engaged a consulting firm to assist in accounting analysis and compilation of restatement adjustments. During the years ended December 31, 2017 and 2016, we incurred $6.2 million and $30.1 million, respectively, of external costs associated with the restatement of our financial statements, an ongoing SEC investigation and remediation activities related to the restatement, of which $2.8 million and $11.2 million, respectively, was recovered from Archrock pursuant to the separation and distribution agreement. We may incur additional cash expenditures related to external legal counsel costs associated with an ongoing SEC investigation surrounding the restatement of our financial statements, of which a portion may be recoverable from Archrock. The following table summarizes the changes to our accrued liability balance related to restatement charges for the years ended December 31, 2016 and 2017 (in thousands): Beginning balance at January 1, 2016 Additions for costs expensed, net Reductions for payments, net Ending balance at December 31, 2016 Additions for costs expensed, net Reductions for payments, net Ending balance at December 31, 2017 Restatement Related Charges $ $ — 18,879 (16,667) 2,212 3,419 (5,052) 579 The following table summarizes the components of charges included in restatement related charges in our statements of operations for the years ended December 31, 2017 and 2016 (in thousands): External accounting costs External legal costs Other Recoveries from Archrock Total restatement related charges Years Ended December 31, 2017 2016 1,071 4,396 753 (2,801) 3,419 $ $ 21,073 7,565 1,448 (11,207) 18,879 $ $ Note 15. Restructuring and Other Charges We incurred restructuring and other charges associated with the Spin-off of $0.6 million, $3.9 million and $15.7 million during the years ended December 31, 2017, 2016 and 2015, respectively. Costs incurred during the years ended December 31, 2017 and 2016 were primarily related to retention awards to certain employees of $0.6 million and $3.1 million, respectively, which were amortized over the required service period of each applicable employee. Costs incurred during the year ended December 31, 2015 were related to non-cash inventory write-downs, financial advisor fees of $4.6 million paid at the completion of the Spin-off, expenses of $3.1 million for retention awards to certain employees, a one-time cash signing bonus paid to our Chief Executive Officer of $2.0 million and costs to start-up certain stand-alone functions of $1.3 million. Non-cash inventory write-downs primarily related to the decentralization of shared inventory components between Archrock’s North America contract operations business and our international contract operations business totaled $4.7 million during the year ended December 31, 2015, of which approximately $4.2 million related to our contract operations segment and $0.5 million related to our product sales segment. The charges incurred in conjunction with the Spin-off are included in restructuring and other charges in our statements of operations. As a result of unfavorable market conditions in North America, combined with the impact of lower international activity due to customer budget cuts driven by lower oil prices, in the second quarter of 2015, we announced a cost reduction plan primarily focused on workforce reductions and the reorganization of certain facilities. We incurred restructuring and other charges associated with the cost reduction plan of $2.6 million, $18.1 million and $15.6 million during the years ended December 31, 2017, 2016 and 2015, respectively. Cost incurred for employee termination benefits during the year ended December 31, 2017 were $2.1 million. Restructuring and other charges incurred during the year ended December 31, 2016 were primarily related to employee termination benefits and the exit from a leased corporate building. Costs incurred for employee termination benefits during the year ended December 31, 2016 were $14.5 million, of which $9.0 million related to our product sales segment. We ceased the use of a corporate building under an operating lease in the second quarter of 2016, and as a result, recorded net charges of $2.9 million during the year ended December 31, 2016. Restructuring and other charges incurred during the year ended December 31, 2015 were primarily related to employee termination benefits, non-cash inventory write-downs and consulting fees. Costs incurred for employee termination benefits during the year ended December 31, 2015 were $9.6 million, of which $6.4 million related to our product sales segment. The non-cash inventory write-downs of $4.0 million were the result of our decision to exit the manufacturing of cold weather packages, which had historically been performed at a product sales facility in North America we decided to close in 2015. These charges are reflected as restructuring and other charges in our statements of operations. We have substantially completed restructuring activities related to the Spin-off and cost reduction plan. No additional costs relating to these restructuring activities are expected to be incurred in future periods. The remaining accrued liability balance at December 31, 2017 primarily relates to contractual lease payments for our previous corporate building that are expected to be paid in early 2018. The following table summarizes the changes to our accrued liability balance related to restructuring and other charges for the years ended December 31, 2015, 2016 and 2017 (in thousands): Spin-off Cost Reduction Plan Total $ 1,083 $ 225 $ Beginning balance at January 1, 2016 Additions for costs expensed Less non-cash income (expense) Reductions for payments Ending balance at December 31, 2016 Additions for costs expensed Less non-cash income (expense) Reductions for payments 3,943 (896) (3,196) 934 599 (223) (1,310) 18,095 435 (16,294) 2,461 2,590 740 (5,179) 612 $ 1,308 22,038 (461) (19,490) 3,395 3,189 517 (6,489) 612 Ending balance at December 31, 2017 $ — $ The following table summarizes the components of charges included in restructuring and other charges in our statements of operations for the years ended December 31, 2017, 2016 and 2015 (in thousands): Financial advisor fees related to the Spin-off $ — $ — $ Years Ended December 31, 2017 2016 2015 Consulting fees Start-up of stand-alone functions Retention awards to certain employees Chief Executive Officer signing bonus Non-cash inventory write-downs Employee termination benefits Net charges to exit the use of a corporate operating lease Other — — 599 — — 2,100 — 490 22 887 3,056 — — 14,473 2,904 696 4,598 1,932 1,332 3,121 2,000 8,707 9,625 — — Total restructuring and other charges $ 3,189 $ 22,038 $ 31,315 The following table summarizes the components of restructuring and other charges incurred in connection with the Spin-off and since the announcement of the cost reduction plan (in thousands): Spin-off Cost Reduction Plan Total Financial advisor fees related to the Spin-off $ 4,598 $ — $ Consulting fees Start-up of stand-alone functions Retention awards to certain employees Chief Executive Officer signing bonus Non-cash inventory write-downs Employee termination benefits Net charges to exit the use of a corporate operating lease Other — 2,219 6,776 2,000 4,700 — — — 1,954 — — — 4,007 26,198 2,904 1,186 Total restructuring and other charges $ 20,293 $ 36,249 $ 4,598 1,954 2,219 6,776 2,000 8,707 26,198 2,904 1,186 56,542 Note 16. Provision for Income taxes Prior to the Spin-off, certain of our operations in the U.S. were included in Archrock’s consolidated federal and state tax returns, and therefore our current and deferred tax provision for applicable periods was computed on a separate return basis. Subsequent to the Spin-off, we file our own consolidated federal and state tax returns in the U.S. The components of income (loss) before income taxes were as follows (in thousands): United States Foreign Income (loss) before income taxes Years Ended December 31, 2017 (43,403) $ 60,242 16,839 $ 2016 (129,864) $ 82,340 (47,524) $ 2015 (7,702) 69,065 61,363 $ $ The provision for income taxes consisted of the following (in thousands): Years Ended December 31, 2017 2016 2015 Current tax provision (benefit): U.S. federal State Foreign Total current Deferred tax provision (benefit): U.S. federal State Foreign Total deferred Provision for income taxes $ — $ 250 25,638 25,888 (5,102) (15) 1,924 (3,193) 22,695 $ (131) $ (792) 54,075 53,152 62,672 2,306 6,112 71,090 383 1,201 63,692 65,276 (29,962) (484) 4,608 (25,838) 39,438 $ 124,242 $ The provision for income taxes for 2017, 2016 and 2015 resulted in effective tax rates on continuing operations of 134.8%, (261.4)% and 64.3%, respectively. The reasons for the differences between these effective tax rates and the U.S. statutory rate are as follows (in thousands): Years Ended December 31, 2017 2016 2015 Income taxes at U.S. federal statutory rate of 35% $ 5,894 $ State income taxes net of federal tax benefit Foreign tax rate differential Foreign tax credits Research and development credits Unrecognized tax benefits Change in valuation allowances Proceeds from sale of joint venture assets Capital contributions or distributions related to Spin-off Change in U.S. deferred taxes related to Tax Reform Act Transition Tax Other Provision for income taxes 361 44,868 (11,224) — 3,332 (48,059) — (1,084) 15,518 10,060 3,029 (16,633) $ (1,841) 29,428 (9,492) (1,024) 3,629 124,850 (3,641) (2,887) — — 1,853 21,477 466 38,984 (17,398) (24,938) 6,001 19,950 (5,315) (77) — — 288 39,438 $ 22,695 $ 124,242 $ Tax legislation enacted and signed into law in 2017 in the U.S. and in Argentina resulted in changes to the statutory tax rates at which certain deferred tax assets and liabilities are recorded. These rate changes resulted in a current period reconciling items between income tax recorded at the U.S. statutory rate and the company’s provision for income taxes of $15.5 million and $(3.1) million, respectively. In the U.S., the valuation allowance that had been previously recorded was reduced as a result of the U.S. statutory rate changes. Deferred income tax balances are the direct effect of temporary differences between the financial statement carrying amounts and the tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The tax effects of temporary differences that give rise to deferred tax assets and deferred tax liabilities are as follows (in thousands): Deferred tax assets: Net operating loss carryforwards Foreign tax credit carryforwards Research and development credit carryforwards Alternative minimum tax credit carryforwards Deferred revenue Other Subtotal Valuation allowances Total deferred tax assets Deferred tax liabilities: Property, plant and equipment Other Total deferred tax liabilities Net deferred tax assets (liabilities) December 31, 2017 2016 $ 86,060 $ 151,393 92,734 31,251 5,575 32,496 47,496 295,612 (222,049) 73,563 (47,954) (24,805) (72,759) 804 $ $ 81,510 31,251 5,055 34,373 49,717 353,299 (276,230) 77,069 (67,139) (15,615) (82,754) (5,685) During the year ended December 31, 2017, our Brazil subsidiary entered into two tax programs: 1) the Tax Regularization Program (the “PRT Program”) pursuant to Brazil Provisional Measure No. 766 issued on January 4, 2017 and 2) the Tax Special Regularization Program (the “PERT Program”) pursuant to Brazil Provisional Measure No. 783 issued on May 31, 2017. These programs allow for the partial settling of debts, both income tax debts and non-income-based tax debts, due by November 30, 2016 and April 30, 2017 to Brazil’s Federal Revenue Service for the PRT Program and PERT Program, respectively, with the use of tax credits, including income tax loss carryforwards. A $15.2 million income tax benefit was recorded during the year ended December 31, 2017 attributable to the reversal of valuation allowances against certain deferred tax assets related to income tax loss carryforwards that were utilized under the PRT Program and PERT Program, including interest income. Additionally, during the year ended December 31, 2017, we incurred $1.8 million in penalties, which is reflected in other (income) expense, net, in our statements of operations, and $2.4 million in interest expense, which is reflected in interest expense in our statements of operations, attributable to the settling of non-income-based tax debts in connection with the PRT Program and the PERT Program. At December 31, 2017, we had U.S. federal net operating loss carryforwards of approximately $118.3 million that are available to offset future taxable income. If not used, the carryforwards begin to expire in 2024. We also had approximately $181.1 million of net operating loss carryforwards in certain foreign jurisdictions (excluding discontinued operations), approximately $148.0 million of which has no expiration date, $7.7 million of which is subject to expiration from 2018 to 2022, and the remainder of which expires in future years through 2037. Foreign tax credit carryforwards of $92.7 million, research and development credits carryforwards of $31.3 million and alternative minimum tax credit carryforwards of $5.6 million are available to offset future payments of U.S. federal income tax. The foreign tax credits will expire in varying amounts beginning in 2020 and research and development credits will expire in varying amounts beginning in 2028. The corporate Alternative Minimum Tax (“AMT”) has been repealed for tax years beginning after December 31, 2017. Companies with AMT credits that have not been utilized may claim a refund in future years for those credits even when no income tax liability exists. We expect our existing AMT credits to be fully utilized or refunded by 2021. We record valuation allowances when it is more-likely-than-not that some portion or all of our deferred tax assets will not be realized. The ultimate realization of the deferred tax assets depends on the ability to generate sufficient taxable income of the appropriate character and in the appropriate taxing jurisdictions in the future. If we do not meet our expectations with respect to taxable income, we may not realize the full benefit from our deferred tax assets which would require us to record a valuation allowance in our tax provision in future years. Management assesses all available positive and negative evidence to estimate our ability to generate sufficient future taxable income of the appropriate character, and in the appropriate taxing jurisdictions, to permit use of our existing deferred tax assets. A significant piece of objective negative evidence is a cumulative loss incurred over a three-year period in a taxing jurisdiction. Prevailing accounting practice is that such objective evidence would limit the ability to consider other subjective evidence, such as our projections for future growth. We incurred a three-year cumulative loss in the U.S. during 2016. Due to this significant negative evidence of cumulative losses, which outweighed the positive evidence of firm sales backlog and projected future taxable income, we were no longer able to support that it was more-likely-than-not that we will have sufficient taxable income of the appropriate character in the future that will allow us to realize our U.S. deferred tax assets. During the year ended December 31, 2016, we recorded a full valuation allowances against our U.S. deferred tax assets resulting in an additional charge of $119.8 million, of which 65.5 million related to U.S. deferred tax assets that existed at December 31, 2015. Pursuant to Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), utilization of loss carryforwards and credit carryforwards, such as foreign tax credits, will be subject to annual limitations due to the historical ownership changes of both Hanover Compressor Company (“Hanover”) and Universal Compression Holdings, Inc. (“Universal”). In general, an ownership change, as defined by Section 382 of the Code, results from transactions increasing the ownership of certain stockholders or public groups in the stock of a corporation by more than 50 percentage points over a three- year period. The merger of Hanover and Universal to form Archrock (formerly Exterran Holdings, Inc.) in August 2007 resulted in such an ownership change for both Hanover and Universal. Our ability to utilize loss carryforwards and credit carryforwards against future U.S. federal income tax may be limited. The limitations may cause us to pay U.S. federal income taxes earlier; however, we do not currently expect that any loss carryforwards or credit carryforwards will expire as a result of these limitations. We consider the earnings of certain of our subsidiaries to be indefinitely reinvested, and accordingly, we have not provided for taxes on these unremitted earnings. If we were to make a distribution from the unremitted earnings of these subsidiaries, we would be subject to taxes payable to various jurisdictions. If our expectations were to change regarding future tax consequences, we may be required to record additional deferred taxes that could have a material effect on our consolidated statement of financial position, results of operations or cash flows. Due to the timing of the enactment of the Tax Reform Act, as discussed below, it is not practicable to estimate the amount of indefinitely reinvested earnings or the deferred tax liability related to the indefinitely reinvested earnings due to the complexities associated with the underlying hypothetical calculations. On December 22, 2017, the U.S. government enacted comprehensive tax legislation. The Tax Reform Act makes broad and complex changes to the U.S. tax code, including, but not limited to, (1) reducing the U.S. federal corporate tax rate from 35% to 21%; (2) requiring companies to pay a one-time transition tax on certain unrepatriated earnings of foreign subsidiaries; (3) generally eliminating U.S. federal income taxes on dividends from foreign subsidiaries; (4) requiring a current inclusion in U.S. federal taxable income of certain earnings of controlled foreign corporations; (5) eliminating the corporate AMT and changing how existing AMT credits can be realized; (6) creating the base erosion anti-abuse tax (“BEAT”), a new minimum tax; (7) creating a new limitation on deductible interest expense; and (8) changing rules related to uses and limitations of net operating loss carryforwards created in tax years beginning after December 31, 2017. Guidance under U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted. In December 2017, the SEC staff issued Staff Accounting Bulletin No. 118, which addresses how a company recognizes provisional amounts when a company does not have the necessary information available, prepared or analyzed (including computations) in reasonable detail to complete its accounting for the effect of the changes in the Tax Reform Act. The measurement period ends when a company has obtained, prepared and analyzed the information necessary to finalize its accounting, but cannot extend beyond one year. For the year ended December 31, 2017, our provision for income tax included the reversal of previously recorded valuation allowances of $5.6 million against our U.S. AMT carryforwards due to the Tax Reform Act which provides for the cancellation of the AMT and allows for a future refund and/or credit against regular income tax carry forwards. In addition, as a result of the reduction in the U.S. corporate tax rate from 35% to 21%, we recorded a provisional estimate of $15.5 million due to the re- measurement of deferred tax assets and liabilities and recorded a provisional estimate of $10.1 million due to the transition tax on undistributed earnings. Both of these were offset by a tax benefit from the reduction of the valuation allowance previously recorded against our U.S. deferred tax assets. Finally, both the tax charges associated with the re-measurement of deferred tax assets and liabilities due to the reduction in the corporate tax rate and the transition tax, and the tax benefit associated with the reduction of the valuation allowance represent provisional amounts. The provisional amounts incorporate assumptions made based upon our current interpretation of the Tax Reform Act and may change as we receive additional clarification and implementation guidance. While we are able to make reasonable estimates of the impact of the reduction in corporate rate and the deemed repatriation transition tax, the final impact of the Tax Reform Act may differ from these estimates, due to, among other things, changes in our interpretations and assumptions, additional guidance that may be issued by the government and actions we may take resulting from these enacted tax laws. We are continuing to analyze additional information to determine the final impact as well as other impacts of the Tax Reform Act. Any adjustments recorded to the provisional amounts will be included in income from operations as an adjustment to our 2018 financial statements. While the Tax Reform Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion provisions: the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) provisions. The GILTI provisions require us to include foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets in our U.S. income tax return. Because of the complexity of the new GILTI tax rules, we will continue to evaluate this provision of the Tax Reform Act and the application of ASC 740, Income Taxes. Under U.S. GAAP, we are allowed to make an accounting policy choice of either (1) treating taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”) or (2) factoring such amounts into our measurement of our deferred taxes (the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules will depend, in part, on analyzing our global income to determine whether we expect to have future U.S. inclusions in taxable income related to GILTI and, if so, what the impact is expected to be. We are in the process of analyzing the impact of the GILTI tax rules. Therefore, we have not made any adjustments related to potential GILTI tax in our consolidated financial statements and have not made a policy decision regarding whether to record deferred tax on GILTI for the year ended December 31, 2017. The BEAT provisions in the Tax Reform Act eliminates the deduction of certain base-erosion payments made to related foreign corporations beginning in 2018, and impose a minimum tax if greater than regular tax. We are in the process of analyzing the impact of the BEAT provision but currently do not expect it will have a material impact on our provision for income tax. A reconciliation of the beginning and ending amount of unrecognized tax benefits (including discontinued operations) is shown below (in thousands): Years Ended December 31, 2017 2016 2015 Beginning balance $ 18,237 $ 14,943 $ Additions based on tax positions related to prior years Additions based on tax positions related to current year Reductions based on settlement with government authority Reductions based on lapse of statute of limitations Reductions based on tax positions related to prior years Ending balance $ 2,034 1,686 (241) (378) (790) 20,548 3,140 256 — (102) — $ 18,237 $ 14,943 8,356 6,448 261 — (122) — We had $20.5 million, $18.2 million and $14.9 million of unrecognized tax benefits at December 31, 2017, 2016 and 2015, respectively, which if recognized, would affect the effective tax rate (except for amounts that would be reflected in income (loss) from discontinued operations, net of tax). We also have recorded $4.3 million, $3.0 million and $3.0 million of potential interest expense and penalties related to unrecognized tax benefits associated with uncertain tax positions (including discontinued operations) as of December 31, 2017, 2016 and 2015, respectively. To the extent interest and penalties are not assessed with respect to unrecognized tax benefits, amounts accrued will be reduced and reflected as reductions in income tax expense. We and our subsidiaries file consolidated and separate income tax returns in the U.S. federal jurisdiction and in numerous state and foreign jurisdictions. Certain of our operations were historically included in Archrock’s consolidated income tax returns in the U.S. federal and state jurisdictions. In addition, certain of Archrock’s operations were historically included in our separate income tax returns in state jurisdictions. Under the Code and the related rules and regulations, each corporation that was a member of the Archrock consolidated U.S. federal income tax reporting group during any taxable period or portion of any taxable period ending on or before the effective time of the Spin-off is jointly and severally liable for the U.S. federal income tax liability of the entire Archrock consolidated tax reporting group for that taxable period. In connection with the Spin-off, we entered into a tax matters agreement with Archrock that allocates the responsibility for prior period taxes of the Archrock consolidated tax reporting group between us and Archrock. State income tax returns are generally subject to examination for a period of three to five years after filing the returns. However, the state impact of any U.S. federal audit adjustments and amendments remains subject to examination by various states for up to one year after formal notification to the states. As of December 31, 2017, we did not have any state audits underway that would have a material impact on our financial position or results of operations. We are subject to examination by taxing authorities throughout the world, including major foreign jurisdictions such as Argentina, Brazil and Mexico. With few exceptions, we and our subsidiaries are no longer subject to foreign income tax examinations for tax years before 2006. Several foreign audits are currently in progress and we do not expect any tax adjustments that would have a material impact on our financial position or results of operations. We believe it is reasonably possible that a decrease of up to approximately $9 million in unrecognized tax benefits may be necessary on or before December 31, 2018 due to the cash and non-cash settlement of audits and the expiration of statutes of limitations. However, due to the uncertain and complex application of tax regulations, it is possible that the ultimate resolution of these matters may result in liabilities which could materially differ from these estimates. Note 17. Related Party Transactions Spin Agreements In connection with the completion of the Spin-off, on November 3, 2015, we entered into several agreements with Archrock and certain subsidiaries of Archrock and, with respect to certain agreements, a subsidiary of Archrock Partners, that govern the Spin-off and the relationship among the parties following the Spin-off, including the following (collectively, the “Spin Agreements”): • The separation and distribution agreement contains the key provisions relating to the separation of our business from Archrock’s business and the distribution of our common stock to its stockholders. The separation and distribution agreement identifies the assets and rights that were transferred, liabilities that were assumed or retained and contracts and related matters that were assigned to us by Archrock or by us to Archrock in the Spin-off and describes how these transfers, assumptions and assignments occurred. Pursuant to the separation and distribution agreement, on November 3, 2015, we transferred net proceeds of $532.6 million from borrowings under the Credit Facility to Archrock to allow for its repayment of a portion of its indebtedness. In addition, the separation and distribution agreement contains certain noncompetition provisions addressing restrictions for three years after the Spin-off on our ability to provide compression contract operations and aftermarket services in the U.S. and on Archrock’s ability to provide compression contract operations and aftermarket services outside of the U.S. and to provide products for sale worldwide that compete with our product sales business, subject to certain exceptions. The separation and distribution agreement also governs the treatment of aspects relating to indemnification, insurance, confidentiality and cooperation. Additionally, the separation and distribution agreement specifies the right of a subsidiary of Archrock to receive payments from EESLP based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries and a $25.0 million cash payment from EESLP promptly following the occurrence of a qualified capital raise which was paid in the second quarter of 2017 after the issuance of the 2017 Notes. See Note 11 for details relating to the issuance of the 2017 Notes. • The tax matters agreement governs the respective rights, responsibilities and obligations of Archrock and us with respect to tax liabilities and benefits, tax attributes, the preparation and filing of tax returns, the control of audits and other tax proceedings and certain other matters regarding taxes. • The employee matters agreement governs the allocation of liabilities and responsibilities between Archrock and Exterran Corporation relating to employee compensation and benefit plans and programs, including the treatment of retirement, health and welfare plans and equity and other incentive plans and awards. The agreement contains provisions regarding stock-based compensation. See Note 19 for additional information relating to the Exterran Corporation Stock Incentive Plan. • The transition services agreement set forth the terms on which Archrock provided to us, and we provided to Archrock, on a temporary basis, certain services or functions that the companies shared prior to the Spin-off. During the year ended December 31, 2016, we recorded selling, general and administrative expense of $0.7 million and other income of $1.3 million associated with services under the transition services agreement. For the period from November 4, 2015 through December 31, 2015, we recorded selling, general and administrative expense of $0.2 million and other income of $0.2 million associated with services under the transition services agreement. • The supply agreement set forth the terms under which we provided manufactured equipment, including the design, engineering, manufacturing and sale of natural gas compression equipment, on an exclusive basis to Archrock and Archrock Partners. The supply agreement had a term of two years, subject to certain cancellation clauses, and was extendable for additional one year terms by mutual agreement of the parties, of which the parties chose not to extend the agreement. Pursuant to the supply agreement, each of Archrock and Archrock Partners was required to purchase their requirements of newly-manufactured compression equipment from us, subject to certain exceptions. Subsequent to November 3, 2015, sales to Archrock and Archrock Partners are considered sales to third parties. Transactions with Affiliates All intercompany transactions and accounts within these financial statements have been eliminated. All affiliate transactions occurring prior to the Spin-off between the international services and product sales businesses of Archrock and the other businesses of Archrock have been included in these financial statements. Prior to the Spin-off, sales of newly-manufactured compression equipment from the product sales business of EESLP to Archrock Partners were used in the U.S. services business of Archrock and were made pursuant to an omnibus agreement between the parties and other affiliates of both entities. Through November 3, 2015, per the omnibus agreement, revenue was determined by the cost to manufacture such equipment plus a fixed margin. During the year ended December 31, 2015, we recorded product sales revenue from affiliates of $154.3 million and cost of sales of $141.9 million from the sale of newly-manufactured compression equipment to Archrock Partners. Subsequent to November 3, 2015, sales to Archrock Partners are considered sales to third parties. Prior to the closing of the Spin-off, EESLP also had a fleet of compression units used to provide compression services in the U.S. services business of Archrock. Revenue prior to the Spin-off was not recognized in our statements of operations for the sale of compressor units by us that were used by EESLP to provide compression services to customers of the U.S. services business of Archrock. The costs of these units were treated as a reduction of parent equity in the balance sheets and a distribution to parent in the statements of cash flows and totaled $32.3 million during the year ended December 31, 2015. Subsequent to November 3, 2015, sales to Archrock are considered sales to third parties. Allocation of Expenses For the periods prior to the Spin-off, the statements of operations also includes expense allocations for certain functions performed by Archrock which have not been historically allocated to its operating segments, including allocations of expenses related to executive oversight, accounting, treasury, tax, legal, human resources, procurement and information technology. Included in our selling, general and administrative expense during the year ended December 31, 2015 was $46.9 million of allocated corporate expenses incurred by Archrock prior to the Spin-off. These costs were allocated to us systematically based on specific department function and revenue. Management believes the assumptions underlying the financial statements, including the assumptions regarding allocating expenses from Archrock, are reasonable. Nevertheless, the financial statements may not be representative of all of the actual expenses that would have been incurred had we been a stand-alone public company during the periods presented and, consequently, may not reflect our combined results of operations, financial position and cash flows had we been a stand-alone public company during the periods presented. Actual costs that would have been incurred if we had been a stand-alone public company would depend on multiple factors, including organizational structure and strategic decisions made in various areas, including information technology and infrastructure. Cash Management Prior to the closing of the Spin-off, EESLP provided centralized treasury functions for Archrock’s U.S. operations, whereby EESLP regularly transferred cash both to and from U.S. subsidiaries of Archrock, as necessary. In conjunction therewith, the intercompany transactions between our U.S. subsidiaries and the other U.S. subsidiaries of Archrock were considered to be effectively settled in cash in these financial statements for the periods prior to the Spin-off. Intercompany receivables/payables from/to related parties arising from transactions with affiliates and expenses allocated from Archrock described above were included in net distributions to parent in the financial statements. Net Distributions to Parent Parent equity, which included retained earnings prior to the Spin-off, represents Archrock’s interest in our recorded net assets. Prior to the Spin-off, all transactions between us and Archrock were presented in the accompanying statement of stockholders’ equity as net distributions to parent. As of November 3, 2015, parent equity was converted to common stock and additional paid-in capital. A reconciliation of net distributions to parent in the statement of stockholders’ equity to the corresponding amount presented in the statement of cash flows for the year ended December 31, 2015 is provided below (in thousands): Year Ended December 31, 2015 Net distributions to parent per the statement of stockholders’ equity Stock-based compensation expenses prior to the Spin-off Net transfers of property, plant and equipment from parent prior to the Spin-off Transfer of net deferred tax liabilities from parent at Spin-off Transfer of other net assets to parent at Spin-off Net distributions to parent per the statement of cash flows $ $ (57,635) (6,066) (7,627) 29,203 1,907 (40,218) Note 18. Stockholders’ Equity The Exterran Corporation amended and restated certificate of incorporation authorizes 250.0 million shares of common stock and 50.0 million shares of preferred stock, each with a par value of $0.01 per share. To effect the Spin-off, on November 3, 2015, Archrock distributed 34,286,267 shares of our common stock to its shareholders. Archrock shareholders received one share of Exterran Corporation common stock for every two shares of Archrock common stock held at the close of business on the Record Date. Additionally, certain of Archrock’s common stock awards that were outstanding prior to the Spin-off were converted to Exterran Corporation’s common stock awards on November 3, 2015. The conversion of Archrock restricted stock into Exterran Corporation restricted stock resulted in the issuance of 505,512 shares of our common stock. See Note 19 for further discussion regarding stock-based compensation. Pursuant to the separation and distribution agreement with Archrock and certain of our and Archrock’s respective affiliates, on November 3, 2015, EESLP transferred $532.6 million of net proceeds from borrowings under the Credit Facility to Archrock to allow it to repay a portion of its indebtedness in connection with the Spin-off. Parent equity, which included retained earnings prior to the Spin-off, represents Archrock’s interest in our recorded net assets. Prior to the Spin-off, all transactions between us and Archrock were presented in the accompanying statements of stockholders’ equity as net distributions to parent. As of November 3, 2015, parent equity was converted to common stock and additional paid-in capital. Comprehensive Income (Loss) Components of comprehensive income (loss) are net income (loss) and all changes in stockholders’ equity during a period except those resulting from transactions with owners. Our accumulated other comprehensive income consists of foreign currency translation adjustments. The following table presents the changes in accumulated other comprehensive income, net of tax, during the years ended December 31, 2015, 2016 and 2017 (in thousands): Accumulated other comprehensive income, January 1, 2015 Income recognized in other comprehensive income (loss) Accumulated other comprehensive income, December 31, 2015 Income recognized in other comprehensive income (loss) Loss reclassified from accumulated other comprehensive income (1) Accumulated other comprehensive income, December 31, 2016 Loss recognized in other comprehensive income (loss) Accumulated other comprehensive income, December 31, 2017 Foreign Currency Translation Adjustment 26,745 2,453 29,198 3,151 15,159 47,508 (1,801) 45,707 $ $ (1) During the year ended December 31, 2016, we reclassified a loss of $15.2 million related to foreign currency translation adjustments to income (loss) from discontinued operations in our statement of operations. This amount represents cumulative foreign currency translation adjustments associated with our Belleli CPE business that previously had been recognized in accumulated other comprehensive income. See Note 3 for further discussion of the sale of our Belleli CPE business. Note 19. Stock-Based Compensation and Awards 2015 Stock Incentive Plan On October 30, 2015, our compensation committee and board of directors each approved the Exterran Corporation 2015 Stock Incentive Plan (the “2015 Plan”) to provide for the granting of stock options, stock appreciation rights, restricted stock, restricted stock units, performance awards, other stock-based awards and dividend equivalents rights to employees, directors and consultants of Exterran Corporation. The 2015 Plan became effective on November 1, 2015. The 2015 Plan also governs awards granted under the Archrock, Inc. 2013 Stock Incentive Plan and the Archrock, Inc. 2007 Amended and Restated Stock Incentive Plan which were adjusted into awards denominated in our common stock in accordance with the terms of the employee matters agreement and/or actions taken by our board of directors or Archrock’s board of directors. Awards granted by Archrock prior to the Spin-off (referred to as “Archrock awards”), which consisted of stock options, restricted stock, restricted stock units and performance units, were generally treated as follows in connection with the Spin-off: • Pre-2015 Awards. Immediately prior to the Spin-off, each outstanding Archrock stock option, restricted stock award, restricted stock unit award and performance unit award granted prior to January 1, 2015, whether vested or unvested, were split into two awards, consisting of an Archrock award and an Exterran Corporation award. For Archrock “incentive stock options” (within the meaning of Section 422 of the Code), the holder of the award had the option to elect, prior to the Spin-off, to convert such options into options denominated in shares of common stock of the applicable holder’s post-spin employer. • 2015 Awards. Each Archrock stock option, restricted stock award, restricted stock unit award and performance unit award that was (i) granted in calendar year 2015 and (ii) held by an individual who became our employee or was engaged by us following the Spin-off were converted solely into an Exterran Corporation award. Archrock did not grant any stock options in the calendar year 2015 prior to the Spin-off. In accordance with the anti-dilution provisions set forth in the individual Archrock award agreements, adjustments to the awards were made to ensure, to the extent possible, that the fair value of each award immediately prior to the Spin-off equaled the fair value of each such award immediately following the Spin-off. Adjustment and substitution of awards did not result in additional compensation expense. Equity awards that were adjusted as described above are generally subject to the same vesting, expiration, performance conditions and other terms and conditions as applied to the underlying Archrock awards immediately prior to the Spin-off. Stock-based compensation expense prior to the Spin-off only related to employees directly involved in our operations, and therefore, excluded stock-based compensation expense related to Archrock employees that supported both the international services and product sales businesses and the other businesses Archrock retained after the Spin-off. Stock-based compensation expense subsequent to the Spin-off relates to employees, directors and consultants of Exterran Corporation, and as discussed above, such awards may consist of awards for either our common stock or Archrock’s common stock. Effective on January 1, 2017, we account for forfeitures as they occur rather than applying an estimated forfeiture rate. The following table presents the stock-based compensation expense included in our results of operations (in thousands): Stock options Restricted stock, restricted stock units, performance units, cash settled restricted stock units and cash settled performance units Restructuring and other charges—stock-based compensation expense Total stock-based compensation expense Stock Options Years Ended December 31, 2017 2016 2015 21 $ 115 $ 348 14,685 662 13,188 1,333 15,368 $ 14,636 $ 7,871 143 8,362 $ $ Stock options are granted at fair market value at the grant date, are exercisable according to the vesting schedule established and generally expire no later than seven years after the grant date. Stock options generally vest one-third per year on each of the first three anniversaries of the grant date. There were no stock options granted during the years ended December 31, 2017, 2016 and 2015. The table below presents the changes in stock option awards for our common stock during the year ended December 31, 2017. Stock Options (in thousands) Weighted Average Exercise Price Per Share Weighted Average Remaining Life (in years) Aggregate Intrinsic Value (in thousands) Options outstanding, January 1, 2017 Granted Exercised Cancelled Options outstanding, December 31, 2017 Options exercisable, December 31, 2017 296 $ — (69) (17) 210 210 17.44 — 16.41 44.23 15.61 15.61 $ 1.5 1.5 3,369 3,369 Intrinsic value is the difference between the market value of our common stock and the exercise price of each stock option multiplied by the number of stock options outstanding for those stock options where the market value exceeds their exercise price. The total intrinsic value of stock options exercised to purchase our common stock during the year ended December 31, 2017 was $0.8 million. Restricted Stock, Restricted Stock Units, Performance Units, Cash Settled Restricted Stock Units and Cash Settled Performance Units For grants of restricted stock, restricted stock units and performance units, we recognize compensation expense over the vesting period equal to the fair value of our common stock at the grant date. We remeasure the fair value of cash settled restricted stock units and cash settled performance units and record a cumulative adjustment of the expense previously recognized. Our obligation related to the cash settled restricted stock units and cash settled performance units is reflected as a liability in our balance sheets. Grants of restricted stock, restricted stock units, performance units, cash settled restricted stock units and cash settled performance units generally vest one-third per year on each of the first three anniversaries of the grant date. The table below presents the changes in restricted stock, restricted stock units, performance units, cash settled restricted stock units and cash settled performance units for our common stock during the year ended December 31, 2017. Non-vested awards granted prior to November 3, 2015 relate to Archrock’s and our employees, directors and consultants. Awards granted subsequent to November 3, 2015 only relate to our employees, directors and consultants. Non-vested awards, January 1, 2017 Granted Vested Change in expected vesting of performance units Cancelled Non-vested awards, December 31, 2017 (1) Weighted Average Grant-Date Fair Value Per Share 17.68 29.90 20.38 30.87 18.63 23.93 Shares (in thousands) 1,292 $ 654 (697) 102 (186) 1,165 (1) Non-vested awards as of December 31, 2017 are comprised of 3,000 cash settled restricted stock units and 1,162,000 restricted shares, restricted stock units and performance units. As of December 31, 2017, we estimate $16.7 million of unrecognized compensation cost related to unvested restricted stock, restricted stock units, performance units, cash settled restricted stock units and cash settled performance units issued to our employees to be recognized over the weighted-average vesting period of 1.8 years. Directors’ Stock and Deferral Plan On October 30, 2015, our compensation committee and board of directors each approved the Exterran Corporation 2015 Directors’ Stock and Deferral Plan (the “Director Plan”). Under the Director Plan, which became effective on October 30, 2015, members of our board of directors may elect, on an annual basis, to receive 25%, 50%, 75% or 100% of their retainer and meeting fees (the “Retainer Fees”) in shares of our common stock in lieu of cash. The number of shares of our common stock issued to each director who elects to have a portion of their Retainer Fees paid in shares in lieu of cash is determined by dividing the applicable dollar amount of such portion by the closing sales price per share of our common stock on the last trading day of the quarter. Any portion of the Retainer Fees paid in cash will be paid to the director following the close of the calendar quarter for which such Retainer Fees were earned. Under the Director Plan, members of the board of directors who elect to receive the Retainer Fees in the form of shares may also elect to defer the receipt of the Retainer Fees until a later date. The maximum aggregate number of shares of our common stock that may be issued under the Director Plan is 125,000 shares, of which 95,184 shares were available to be issued under the plan as of December 31, 2017. The board of directors will administer the Director Plan and has the authority to make certain equitable adjustments under the Director Plan in the event of certain corporate transactions. Note 20. Net Income (Loss) Per Common Share Basic net income (loss) per common share is computed using the two-class method, which is an earnings allocation formula that determines net income (loss) per share for each class of common stock and participating security according to dividends declared and participation rights in undistributed earnings. Under the two-class method, basic net income (loss) per common share is determined by dividing net income (loss) after deducting amounts allocated to participating securities, by the weighted average number of common shares outstanding for the period. Participating securities include our unvested restricted stock and certain stock settled restricted stock units that have nonforfeitable rights to receive dividends or dividend equivalents, whether paid or unpaid. During periods of net loss from continuing operations, no effect is given to participating securities because they do not have a contractual obligation to participate in our losses. Diluted net income (loss) per common share is computed using the weighted average number of common shares outstanding adjusted for the incremental common stock equivalents attributed to outstanding options to purchase common stock and non- participating restricted stock units, unless their effect would be anti-dilutive. The following table presents a reconciliation of basic and diluted net income (loss) per common share for the years ended December 31, 2017, 2016 and 2015 (in thousands, except per share data): Numerator for basic and diluted net income (loss) per common share: Income (loss) from continuing operations Income (loss) from discontinued operations, net of tax Less: Net income attributable to participating securities Net income (loss) — used in basic and diluted net income (loss) per common share Weighted average common shares outstanding including participating securities Less: Weighted average participating securities outstanding Weighted average common shares outstanding — used in basic net income (loss) per common share Net dilutive potential common shares issuable: On exercise of options and vesting of restricted stock units Weighted average common shares outstanding — used in diluted net income (loss) per common share Net income (loss) per common share: Basic Diluted Years Ended December 31, 2017 2016 2015 (5,856) $ 39,736 — (171,766) $ (56,171) — 21,925 4,723 (115) 33,880 $ (227,937) $ 26,533 35,961 (1,002) 35,489 (921) 34,437 (149) 34,959 34,568 34,288 * * 16 34,959 34,568 34,304 0.97 0.97 $ $ (6.59) $ (6.59) $ 0.78 0.78 $ $ $ $ * Excluded from diluted net income (loss) per common share as their inclusion would have been anti-dilutive.

Retirement Benefit Plan Years Ended December 31, 2017 2016 2015 43 81 124 225 50 275 62 — 62 Our 401(k) retirement plan provides for optional employee contributions for certain employees who are U.S. citizens up to the Internal Revenue Service limit and discretionary employer matching contributions. During the years ended December 31, 2017, 2016 and 2015, we made discretionary matching contributions to each participant’s account at a rate of (i) 100% of each participant’s first 1% of contributions plus (ii) 50% of each participant’s contributions up to the next 5% of eligible compensation. For the periods prior to the Spin-off, we allocated costs incurred by Archrock for employer matching contributions. Costs incurred for employer matching contributions of $2.4 million, $2.4 million and $3.6 million during the years ended December 31, 2017, 2016 and 2015, respectively, are presented as selling, general and administrative expense in our statements of operations. Note 22. Commitments and Contingencies Rent expense relating to facilities and other operating leases for 2017, 2016 and 2015 was approximately $9.3 million, $9.9 million and $13.1 million, respectively. Commitments for future minimum rental payments with terms in excess of one year as of December 31, 2017 are as follows (in thousands): 2018 2019 2020 2021 2022 Thereafter Total Guarantees December 31, 2017 $ $ 4,759 2,565 2,063 1,895 1,890 10,680 23,852 We have issued the following guarantees that are not recorded in our accompanying balance sheet (dollars in thousands): Performance guarantees through letters of credit (1) Standby letters of credit Bid bonds and performance bonds (1) Maximum potential undiscounted payments Term Maximum Potential Undiscounted Payment as of December 31, 2017 2018-2021 $ 2018 2018-2027 $ 62,280 720 87,536 150,536 (1) We have issued guarantees to third parties to ensure performance of our obligations, some of which may be fulfilled by third parties. Contingencies See Note 3 and Note 9 for a discussion of our gain contingencies related to assets that were expropriated in Venezuela. Pursuant to the separation and distribution agreement, EESLP contributed to a subsidiary of Archrock the right to receive payments based on a notional amount corresponding to payments received by our subsidiaries from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets promptly after such amounts are collected by our subsidiaries until Archrock’s subsidiary has received an aggregate amount of such payments up to the lesser of (i) $125.8 million, plus the aggregate amount of all reimbursable expenses incurred by Archrock and its subsidiaries in connection with recovering any PDVSA Gas default installment payments following the completion of the Spin-off or (ii) $150.0 million. Our balance sheets do not reflect this contingent liability to Archrock or the amount payable to us by PDVSA Gas as a receivable. Pursuant to the separation and distribution agreement, we transferred cash of $19.7 million and $49.2 million to Archrock during the years ended December 31, 2017 and 2016, respectively. The transfers of cash were recognized as reductions to additional paid-in capital in our financial statements. As of December 31, 2017, the remaining principal amount due to us from PDVSA Gas in respect of the sale of our and our joint ventures’ previously nationalized assets was approximately $21 million. In subsequent periods, the recognition of a liability, if applicable, resulting from this contingency to Archrock is expected to impact equity, and as such, is not expected to have an impact on our statements of operations. In addition to U.S. federal, state and local and foreign income taxes, we are subject to a number of taxes that are not income- based. As many of these taxes are subject to audit by the taxing authorities, it is possible that an audit could result in additional taxes due. We accrue for such additional taxes when we determine that it is probable that we have incurred a liability and we can reasonably estimate the amount of the liability. As of December 31, 2017 and 2016, we had accrued $2.8 million and $3.1 million, respectively, for the outcomes of non-income-based tax audits and had related indemnification receivables from Archrock of $1.5 million and $1.7 million, respectively. We do not expect that the ultimate resolutions of these audits will result in a material variance from the amounts accrued. We do not accrue for unasserted claims for tax audits unless we believe the assertion of a claim is probable, it is probable that it will be determined that the claim is owed and we can reasonably estimate the claim or range of the claim. We do not have any unasserted claims from non-income-based tax audits that we have determined are probable of assertion. We also believe the likelihood is remote that the impact of potential unasserted claims from non-income-based tax audits could be material to our financial position, but it is possible that the resolution of future audits could be material to our results of operations or cash flows for the period in which the resolution occurs. Our business can be hazardous, involving unforeseen circumstances such as uncontrollable flows of natural gas or well fluids and fires or explosions. As is customary in our industry, we review our safety equipment and procedures and carry insurance against some, but not all, risks of our business. Our insurance coverage includes property damage, general liability, commercial automobile liability and other coverage we believe is appropriate. We believe that our insurance coverage is customary for the industry and adequate for our business; however, losses and liabilities not covered by insurance would increase our costs. Additionally, we are substantially self-insured for workers’ compensation and employee group health claims in view of the relatively high per-incident deductibles we absorb under our insurance arrangements for these risks. Losses up to the deductible amounts are estimated and accrued based upon known facts, historical trends and industry averages. Litigation and Claims In the ordinary course of business, we are involved in various pending or threatened legal actions. While management is unable to predict the ultimate outcome of these actions, it believes that any ultimate liability arising from any of these actions will not have a material adverse effect on our financial position, results of operations or cash flows. However, because of the inherent uncertainty of litigation and arbitration proceedings, we cannot provide assurance that the resolution of any particular claim or proceeding to which we are a party will not have a material adverse effect on our financial position, results of operations or cash flows. Contemporaneously with filing the Form 8-K on April 26, 2016, we self-reported the errors and possible irregularities at Belleli EPC to the SEC. Since then, we have been cooperating with the SEC in its investigation of this matter, which has included responding to a subpoena for documents related to the restatement and of our compliance with the U.S. Foreign Corrupt Practices Act (“FCPA”), which were also provided to the Department of Justice at its request. The SEC staff has notified us that they have concluded their investigation concerning our compliance with the FCPA and that they do not intend to recommend an enforcement action concerning our compliance with the FCPA. The DOJ has similarly informed us that it does not intend to proceed with any further investigation or enforcement. The SEC’s investigation related to the circumstances giving rise to the restatement is continuing, and we are presently unable to predict the duration, scope or results or whether the SEC will commence any legal action. Indemnifications In conjunction with, and effective as of the completion of, the Spin-off, we entered into the separation and distribution agreement with Archrock, which governs, among other things, the treatment between Archrock and us relating to certain aspects of indemnification, insurance, confidentiality and cooperation. Generally, the separation and distribution agreement provides for cross-indemnities principally designed to place financial responsibility for the obligations and liabilities of our business with us and financial responsibility for the obligations and liabilities of Archrock’s business with Archrock. Pursuant to the agreement, we and Archrock will generally release the other party from all claims arising prior to the Spin-off that relate to the other party’s business, subject to certain exceptions. Additionally, in conjunction with, and effective as of the completion of, the Spin-off, we entered into the tax matters agreement with Archrock. Under the tax matters agreement and subject to certain exceptions, we are generally liable for, and indemnify Archrock against, taxes attributable to our business, and Archrock is generally liable for, and indemnify us against, all taxes attributable to its business. We are generally liable for, and indemnify Archrock against, 50% of certain taxes that are not clearly attributable to our business or Archrock’s business. Any payment made by us to Archrock, or by Archrock to us, is treated by all parties for tax purposes as a nontaxable distribution or capital contribution, respectively, made immediately prior to the Spin-off. Note 23. Reportable Segments and Geographic Information We manage our business segments primarily based upon the type of product or service provided. We have three reportable segments: contract operations, aftermarket services and product sales. In our contract operations segment, we own and operate natural gas compression equipment and crude oil and natural gas production and processing equipment on behalf of our customers outside of the U.S. In our aftermarket services segment, we sell parts and components and provide operations, maintenance, overhaul, upgrade, commissioning and reconfiguration services to customers outside of the U.S. who own their own compression, production, processing, treating and related equipment. In our product sales segment, we design, engineer, manufacture, install and sell natural gas compression packages as well as equipment used in the production, treating and processing of crude oil and natural gas to our customers throughout the world and for use in our contract operations business line. We evaluate the performance of our segments based on gross margin for each segment. Revenue includes sales to external customers and affiliates. We do not include intersegment sales when we evaluate our segments’ performance. During the years ended December 31, 2017 and 2015, Archrock and its affiliates accounted for approximately 12% and 11% of our total revenue, respectively. During the year ended December 31, 2016, Petroleo Brasileiro S.A. accounted for approximately 10% of our total revenue. No other customer accounted for more than 10% of our total revenue in 2017, 2016 and 2015. See Note 17 for further discussion on transactions with affiliates.

Additional Notes: • • In the fourth quarter of 2017, we substantially exited our Belleli EPC business and, in accordance with GAAP, it is reflected as discontinued operations in our financial statements for all periods presented (see Note 3). In conjunction with the planned disposition of Belleli CPE, we recorded impairments of long-lived assets and current assets that totaled $61.6 million and $7.1 million during the first quarter and second quarter of 2016, respectively. We completed the sale of Belleli CPE in August 2016 for cash proceeds of $5.5 million. Belleli CPE is reflected as discontinued operations in our financial statements for all periods presented (see Note 3). • Due to significant negative evidence of cumulative losses in the U.S., we are no longer able to support that it is more- likely-than-not that we will have sufficient taxable income of the appropriate character in the future that will allow us to realize our U.S. deferred tax assets. As a result, we recorded a full valuation allowance against our U.S. deferred tax assets resulting in additional charges of $88.0 million, $13.6 million and $18.2 million during the second quarter, third quarter and fourth quarter of 2016, respectively (see Note 16). • During the second quarter, third quarter and fourth quarter of 2016, we incurred costs of $7.9 million, $12.3 million and $9.9 million, respectively, associated with the restatement of our financial statements and related SEC investigation, of which $11.2 million of cash was recovered from Archrock in the fourth quarter of 2016 pursuant to the separation and distribution agreement. During the first quarter, second quarter, third quarter and fourth quarter of 2017, we incurred costs of $2.2 million, $1.6 million, $2.0 million and $0.4 million, respectively, associated with an ongoing SEC investigation and remediation activities related to the restatement, of which $2.8 million was recovered from Archrock in the second quarter of 2017 (see Note 14). EXTERRAN CORPORATION SCHEDULE II VALUATION AND QUALIFYING ACCOUNTS (In thousands) Description Allowance for doubtful accounts deducted from accounts receivable in the balance sheets December 31, 2017 December 31, 2016 December 31, 2015 Allowance for obsolete and slow moving inventory deducted from inventories in the balance sheets December 31, 2017 December 31, 2016 December 31, 2015 Allowance for deferred tax assets not expected to be realized December 31, 2017 December 31, 2016 December 31, 2015 Balance at Beginning of Period Charged to Costs and Expenses Deductions Balance at End of Period $ 5,383 $ 2,868 2,133 $ 12,877 $ 14,486 8,660 863 2,972 3,292 1,276 756 15,590 $ $ $ $ 858 (1) 457 (1) 2,557 (1) 3,802 (2) 2,365 (2) 9,764 (2) 5,388 5,383 2,868 10,351 12,877 14,486 $ 276,230 $ 4,343 $ 142,960 98,607 144,852 79,394 (3) 58,524 (4) 11,582 (4) 35,041 (4) $ 222,049 276,230 142,960 (1) (2) (3) (4) Uncollectible accounts written off.
