PART I

ITEM 1BUSINESS

Overview

Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “we”, “our” and “us”) (NASDAQ: ERII) is an engineering-driven technology company that engineers, designs, manufactures and supplies solutions for industrial fluid flow processes. The Company offers technologies which can drive meaningful, immediate cost savings and operational efficiencies for our customers. Currently, we operate in two markets - water and oil & gas, and our products are utilized in these markets to either recycle and convert wasted pressure energy into a usable asset or preserve pumps that are subject to hostile processing environments.

Energy Recovery was incorporated in Virginia in 1992 and reincorporated in Delaware in 2001. Our headquarters and principal research, development, and manufacturing facility is located in California. We are also constructing a new facility in Texas, which we hope to complete in 2019. We maintain direct sales offices and technical support centers in Europe, the Middle East and Asia.

Water

For more than 20 years, Energy Recovery has been developing innovative and efficient technologies and solutions for the reverse osmosis water desalination industry. Climate change, increasing water scarcity, as well as population and economic growth across the globe are driving water demand for human, agricultural, and industrial use. Apart from seasonal variations, the supply of fresh water generally remains fixed, and in some geographic areas is falling, and cannot keep pace with this growing demand. Desalination of seawater, brackish water and wastewater offers one solution to water scarcity needs around the world. In many parts of the world, desalination contributes significantly to the freshwater supply.

Solutions

We are the market leader in the engineering, design, manufacturing and supply of energy recovery devices (“ERDs”) to the global reverse osmosis desalination market. Our ERDs are categorized into two technology groups: positive displacement isobaric ERDs, namely our proprietary Pressure Exchanger (“PX Pressure Exchanger”), and centrifugal-type ERDs such as our hydraulic turbochargers (“Turbochargers”). We also manufacture high-performance and high-efficiency pumps that are utilized in the reverse osmosis desalination process.

Energy Recovery Devices

Prior to the introduction of ERDs, the expense of reverse osmosis desalination was often cost prohibitive due to the high energy needs required in the process. Generally speaking, energy intensive pumps are used to pressurize the feed water, weather seawater or brackish water, which is then forced through a membrane that removes the salts and minerals. The process results in potable water, suitable for human, agricultural and industrial use. In the case of seawater reverse osmosis (“SWRO”) desalination, for example, this process results in a highly concentrated and pressurized concentrate stream. Prior to the adoption of ERDs, this concentrate stream was often discharged back into the world’s oceans after dissipating the pressure through throttle valves, thereby wasting the pressure energy. The repeated pressurization of the feed water and subsequent dissipation of the pressure energy in the discharge water was inefficient and resulted in tremendous amounts of wasted energy that made SWRO desalination substantially more expensive that alternative water production options.

When introduced, ERDs fundamentally altered this paradigm by capturing and reusing this wasted pressure energy. Rather than dissipating the pressure energy from the discharge brine, ERDs such as our PX Pressure Exchanger can transfer the pressure energy from the discharge water directly to the unprocessed feed water, thereby reducing the amount of ongoing pressure energy required by the processes’ pumps. This results in a much more efficient process as the size of the high-pressure pumps and the corresponding energy usage are reduced. As a result, ERDs have made SWRO desalination a viable economic option in the production of potable water.


6



The brackish water reverse osmosis (“BWRO”) desalination process is identical to that of the SWRO desalination process. Brackish water typically has lower salt content than seawater, therefore fewer solids need to be removed and less energy is expended on pressurizing the feed water. The amount of salts in the feedwater will ultimately determine the system design and operating conditions which, in turn, will drive decisions related to the specification or type of energy recovery device to be employed, if any. Due to the lower cost involved, our Turbocharger devices generally have characteristics more applicable to BWRO, although this is not always the case.

The PX Pressure Exchanger, high efficiency positive-displacement isobaric energy recovery device. Our patented PX Pressure Exchanger technology consists of a ceramic rotor supported by a highly efficient hydrodynamic and hydrostatic bearing system. Our PX Pressure Exchangers compete largely in the SWRO industry, or in higher salination BWRO desalination applications, and enable desalination plant operators to recover otherwise wasted hydraulic pressure energy from a high-pressure fluid flow and transfer the energy to a low-pressure fluid flow.

Turbochargers, high efficiency centrifugal energy recovery device. Our Turbochargers are designed for low-pressure brackish and high-pressure seawater reverse osmosis systems, as well as various other water treatment applications. Our Turbochargers provide high efficiency with state-of-the-art engineering and configuration. Designed for maximum durability, reliability and optimum efficiency, our Turbochargers offer substantial savings, and the custom-designed hydraulics allow for optimum performance over a wide range of operating conditions. Our Turbochargers complete primarily in BWRO desalination applications, where the systems have characteristics more applicable to our Turbocharger technology. However, our Turbocharger technology is also implemented in SWRO desalination applications where initial cost, simplicity and / or low energy costs are key factors in the decision-making process.

Pumps

High efficiency pumps, high-pressure feed and high-pressure circulation pumps. In addition to ERDs, water reverse osmosis desalination requires specialized high-pressure feed and circulation pumps. These devices, in combination with ERDs, must efficiently pressurize and circulate feedwater to the membranes to purify water. Plant operators require specialized pumps with performance matched to the requirements of the membranes and energy recovery devices. To minimize plant costs these pumps must provide high energy efficiency and reliability with low maintenance requirements. Specifically designed for the reverse osmosis industry, our pumps utilize our material science and hydraulic design expertise. Designed for maximum durability, reliability, and optimum efficiency, our pumping systems offer users savings, while the investment cast components and optimized fluid pathways ensure maximum performance.

We manufacture and / or supply specialized high-pressure feed and circulation pumps for only a portion of the markets served by our ERD solutions, generally in small- to medium-sized desalination plants. Our high-pressure feed pumps are designed to pressurize the membrane feed flow and overcome the osmotic pressure requirements of the feed water resulting in the production of permeate water. Our high-pressure circulation pumps are designed to “circulate” and control the high-pressure flow rates through the PX Pressure Exchanger and to compensate for small pressure losses across the membrane, PX Pressure Exchanger and associated process piping.

Markets

Seawater, brackish, and wastewater reverse osmosis desalination have been our markets for revenue generation to date. The water market ranges from small desalination plants such as those used in cruise ships and resorts, to mega-project desalination plants deployments globally that process 50,000 cubic meters of water per day and above. Because of the geographical location of many significant water desalination projects, geopolitical and economic events can influence the timing of expected projects. We anticipate that markets traditionally not associated with desalination, including the United States (“U.S.”) will inevitably develop and provide further revenue growth opportunities.


7



Greenfield

The greenfield market represents newly constructed reverse osmosis desalination projects. These facilities vary in size, scope and geography. Largescale greenfield projects are typically public in nature and involve a formal tendering process. Smaller greenfield projects may be private in nature, but typically still involve a formal tendering process. We work directly with the project bidders, generally large engineering, procurement and construction (“EPC”) firms, end-users and industry consultants to scope in our products prior to the project being awarded, where possible. Once the project is awarded to an EPC, our normal sales process ensues. The greenfield market has been the key market for our water business. This market is highly competitive, and the tendering process pays close attention to the cost to desalinate water (i.e., dollars per cubic meter of water produced). Our PX Pressure Exchanger’s industry-leading efficiency for ERDs in the desalination industry has allowed us to remain competitive.

Retrofit

The retrofit market represents existing water facilities that are currently in operation utilizing legacy technologies. These facilities and their owners not only encounter issues with low-efficiency legacy technologies, but also encounter capital expenditure and “know-how” issues that may prevent them from retrofitting plants. Typical retrofits include improvements to existing operations, equipment upgrades and potential expansions of existing capacity. We leverage our best-in-class solutions and “know how” to unseat existing technology by implementing water production efficiency measures to reduce overall power consumed, repair and maintenance costs and avoid costly capital upgrades, as well as increase throughput and/or plant availability. These retrofit opportunities may or may not have a formal tendering process. We typically approach the plant operators, owners and/or end-users of these facilities to present our value-proposition.

Service & Aftermarket
    
The service & aftermarket market is comprised of existing water facilities that have our solutions installed or in operation. We provide spare and repaired components, field services and various commissioning activities to our customer base. We leverage our water expertise in supporting our existing installed base to ensure that our solutions are being operated effectively and efficiently. Readily available aftermarket products and services are required by our industry partners and customers in order maximize plant availability and profits.

Customers

We sell our energy recovery devices and pumps to (1) major international EPC firms that can design, build, own and operate large-scale desalination plants (mega projects); (2) original equipment manufacturers (“OEM”) which are companies that supply equipment and packaged solutions for small- to medium-sized desalination plants, and national, state and local municipalities worldwide; and (3) plant owners and/or operators who can utilize our technology to upgrade or keep their plant running, or retrofit their existing plant equipment with various efficiency measures to optimize operations by reducing overall power consumed and reduce other operating costs in the desalination process.

Large Engineering, Procurement and Construction Firms

A significant portion of our revenue has historically come from sales to large EPC firms worldwide which have the required desalination expertise to engineer, undertake procurement for, construct, and sometimes own and operate, large desalination plants or mega-projects. Due to the enormous volume of water processed by these mega-projects, ongoing operating costs rather than initial capital expenditures is the key factor in their selection of an ERD solution. As such, EPCs most often select our PX Pressure Exchangers, which offers the highest efficiency and total life-cycle-cost savings to the end client. We work with these EPC firms to specify our PX Pressure Exchanger solutions for their plant designs. The time between project tender and shipment can range from 16 to 36 months, or more. Each mega-project typically represents revenue opportunities ranging from $1 million to $10 million.

We estimate that the total capital investments in these mega-projects may fall between $50 million to $1 billion or more. Due to the large capital investments needed to fund these projects, which are typically provided by national or local governments, these projects are more susceptible to macroeconomic and regional risks, such as economic downturns, currency shocks, or political risks.


8



Original Equipment Manufacturers

We sell a broad set of our products to OEMs including our PX Pressure Exchangers, Turbochargers, high-pressure pumps, and circulation “booster” pumps. Our sale of solutions and services to OEM suppliers are for integration and use in small- to medium-sized desalination plants processing up to 50,000 cubic meters of water per day located in local municipalities, hotels and resorts, power plants, cruise ships, farm operations, among others. In addition, these OEMs purchase our solutions for “quick water” or emergency water solutions.

Unlike mega-projects, OEM projects are smaller in scope and, as such, the initial capital expenditure, rather than future ongoing operating costs, is often the key factor in selection of an ERD solution. Accordingly, we sell not only our PX Pressure Exchanger, but also our Turbochargers, which offer a lower cost alternative to the PX Pressure Exchanger. The typical time from project tender and shipment can range from one to 12 months. OEM projects typically represent revenue opportunities of up to $1 million or more.

Capital investments in OEM projects can be as high as $100 million, but typically range between $10 - $50 million. Due to the lower capital investment of these projects, such projects are more likely to be privately financed, or financed by local municipalities. Due to a more diverse customer base and source of financing, OEM projects tend to be less susceptible to economic and regional shocks, and to provide a more stable source of revenue to the company.

End-users and Service Providers

Our existing and expanding installed base of energy recovery and pump products in water plants has created a growing customer base comprised of plant operators and service providers. These customers purchase spare parts, replacement parts, and service contracts, as well as utilize our field service expertise to perform maintenance and repairs. Owners and operators of older plants without effective energy recovery devices, and newer plants with devices manufactured by our competitors, purchase our equipment to retrofit plants to realize operational expense reductions or expansions in plant capacity.

Competition

The market for ERDs and pumps in the water treatment market is competitive. As the demand for fresh water increases and the market expands, we expect competition to persist and intensify.

We have three main competitors for our ERDs: Flowserve Corporation (“Flowserve”), Fluid Equipment Development Company (“FEDCO”), and Danfoss Group (“Danfoss”). We believe our solutions offer a competitive advantage compared to our competitor’s solutions because our ERDs provide the lowest life-cycle cost and are therefore the most cost-effective ERD solutions for the reverse osmosis desalination industry over time.

In the market for large mega-projects, our PX Pressure Exchanger competes primarily with Flowserve’s DWEER product. We believe our PX Pressure Exchangers have a competitive advantage as compared to the DWEER product because our devices are made with highly durable and corrosion-resistant ceramic parts that are designed for a life of more than 25 years, are warranted for high efficiencies, cause minimal unplanned downtime, and offer lower lifecycle costs. Additionally, the PX Pressure Exchanger offers optimum scalability with a quick startup as well as no scheduled maintenance.

In the market for small-to-medium-sized desalination plants, our ERD solutions compete with FEDCO’s turbochargers and Danfoss’s iSave energy recovery device. We believe that our PX Pressure Exchangers have a distinct competitive advantage over these solutions because our devices provide up to 98% energy efficiency, have lower lifecycle maintenance costs, and are made of highly durable and corrosion-resistant ceramic parts. We also believe that our Turbochargers compete favorably with FEDCO’s turbochargers based on efficiency, price and because our turbochargers have design advantages that enhance efficiency, operational flexibility, and serviceability.

In the applicable market and flow ranges that we serve for high-pressure pumps and circulation pumps, our solutions compete with pumps manufactured by Clyde Union Ltd.; FEDCO; Flowserve; KSB Aktiengesellschaft; Torishima Pump Mfg. Co., Ltd.; Sulzer Pumps, Ltd.; and other companies. We believe that our pump solutions are competitive with these solutions because our pumps are developed specifically for reverse osmosis desalination, are highly efficient, feature product-lubricated bearings, and are often purchased with our ERDs in small- to medium-sized plants.

Sales and Marketing


9



Our strategically located direct salesforce offers our products through capital sale to our customers around the world. We have sales offices in the United States, Madrid, Shanghai, and Dubai, and we maintain a sales and service footprint in strategic territories allowing rapid response to our customers’ needs. Our team is composed of individuals with many years of desalination and water expertise and deep references throughout the industry. Aligning to the geographic breadth of our current and potential future customers, our product marketing approach includes a strategic presence at water industry events across various regions. In addition, we leverage our industry and market intelligence to develop new solutions and services that can be adopted by our growing customer base.

A significant portion of our revenue is from outside of the U.S. Additional segment and geographical information regarding our product revenue is included in Note 13, “Geographical Information and Concentrations” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K.

Operations

Our water products are manufactured at our facility located in San Leandro, California, where our PX Pressure Exchangers, Turbochargers and pumps are produced, assembled, and tested. Our 100,000 sq. ft manufacturing area includes an advanced ceramics manufacturing facility and testing laboratory, five hydraulic performance testing loops, CNC machines, assembly stations and warehouse. Ceramic components for the PX device are manufactured in-house from high-grade, raw alumina to the final product. Components for our other products also undergo final precision finishing in San Leandro to protect the proprietary nature of our manufacturing methods and product designs and to maintain premium quality standards. The availability of multiple test loops allows us to test every water product we manufacture to its full rated operating conditions.

We obtain raw, processed and certain pre-machined materials from various suppliers to support our manufacturing operations. A limited number of these suppliers are near sole-source to maintain material consistency and support new product development. A qualified redundant material source exists in all cases.

Our production facility operates under the principles of Lean Manufacturing and continuously seeks ways to improve product and process performance. Our manufacturing operations is certified to ISO9001:2015 standards.

Water field activities are conducted by our after-market and field service organization on-site at customer locations.

Seasonality

We often experience substantial fluctuations in product revenue from quarter-to-quarter and from year-to-year because a single order for our ERDs by a large EPC firm for a particular plant may represent a significant portion of our revenue. Prior to 2018, our EPC customers tended to order a significant amount of equipment for delivery in the fourth quarter, and as a consequence, a significant portion of our annual sales typically occurred during the fourth quarter. This trend did not repeat itself in 2018, however, and seasonality as experienced in prior years may not be the same in future years.


Oil & Gas

Across oil & gas markets, highly pressurized fluid flows are required to extract and process hydrocarbons. These pressurized fluid flows are a necessity but come at a high cost to the oil & gas industry. In the upstream sector, high rates of flow, high pressure differentials and hostile (e.g., corrosive, erosive or abrasive) fluids lead to rapid degradation of expensive pressure pumping equipment. In the mid-stream and down-stream sectors, pressure energy becomes a waste product at various stages of oil and gas processing thereby driving excessive energy usage and cost. Oil & gas operators seek ways to reduce these costs and improve overall productivity.


10



Markets

Upstream Sector

Hydraulic fracturing is a well-stimulation technique in which pressurized liquid containing a highly abrasive, proppant-laden fluid is injected into a wellbore. Oilfield service (“OFS”) providers utilize high-pressure hydraulic fracturing pumps (commonly referred to as “frac-pumps”) to pressurize fracturing fluid (commonly referred to as “frac-fluid”) at treating pressures up to 15,000 pounds per square inch (“psi”). This frac-fluid is sent from the frac-pumps through traditional missile manifolds into the wellbore to create cracks in the deep-rock formations thereby permitting oil and gas extraction. These frac-pumps are routinely destroyed by the abrasive frac-fluids used during the hydraulic fracturing process causing significant OFS operator costs associated with excessive downtime, repairs, maintenance, and capital equipment redundancy.

During mud pumping in the drilling process, a drilling fluid (commonly referred to as “drilling mud”) is circulated from a mud pit through the wellbore utilizing high-pressure mud pumps, which pressurize the drilling mud at treating pressures up to 7,500 psi, to control formation pressures, lubricate the drill bit, and to remove cuttings. Although the existing mud pumping process removes most of the solids from the drilling mud, debris and sand often remain. The pumps circulating the drilling mud is therefore subjected to extreme wear, resulting in burdensome repair and maintenance costs. Components of these mud pumps are routinely destroyed by the hostile drilling mud used during the mud pumping process causing OFS operators significant costs associated with excessive downtime, repairs, maintenance, capital equipment redundancy, safety, and rig mobilization.

OFS operators have long sought ways to ruggedize or extend the life of pumps thereby reducing costs in both the hydraulic fracturing and drilling processes. We believe the most efficient method of extending the life of these pumps is to isolate the high-pressure pumps from the abrasive fluids completely, thereby enabling OFS operators to realize immediate and long-term savings in the form of reduced downtime, repairs and maintenance costs and capital equipment redundancy.

Midstream and Downstream Sectors

Today, natural gas is typically processed by removing acid gases such as carbon dioxide and hydrogen sulfide before it is ready for distribution and use. A common acid gas removal process uses an amine solvent to absorb acid gases in a high-pressure contactor column. Having absorbed the carbon dioxide and hydrogen sulfide, the pressurized (rich) amine is then depressurized and processed into regenerated (lean) amine for reuse. An ERD, such as a Turbocharger, can recover the energy wasted during this reduction in pressure of the amine. This recovered energy can then be converted to electricity, or hydraulic energy, which eliminates the need for a high-pressure pump. Fewer high-pressure pumps reduce capital expenditures, and energy and maintenance costs, positively impacting plant availability.

Within pipeline applications, crude oil or final hydrocarbon products must be pressurized to travel from upstream gathering facilities or refineries, to terminals and tank farms. Fluid pressure builds within the pipeline during transport, and this pressure must be reduced before storing the liquid. This required pressure-drop, typically managed through a control valve that simply dissipates the energy into the atmosphere, represents an opportunity to generate electricity from otherwise wasted pressure energy.

Solutions

Our technology solutions seek to preserve or eliminate pumping technology in hostile processing environments or convert wasted pressure energy into a reusable asset. Our core oil & gas solutions based upon PX Pressure Exchanger technology, the VorTeq and MTeq, isolate high cost pumping equipment from hostile processing fluids. Our centrifugal line of solutions based upon our Turbocharger technology, the IsoBoost and IsoGen, recycle otherwise lost pressure energy.

Upstream Sector

VorTeq, a PX solution for hydraulic fracturing applications: The VorTeq technology isolates and preserves costly frac-pumps by re-routing hostile frac-fluid away from the frac-pumps, and ultimately enables a more efficient pumping model. Using VorTeq, the frac-pumps will process only clean fluid, which leads to reduced repairs and maintenance costs, reduced capital costs by extending frac-pump life expectancy, and the elimination of redundant capital equipment. Our VorTeq techlology is currently in the research and development (“R&D”) stage. We completed a substantial re-design of the VorTeq during 2017 and have progressed the technology significantly in 2018. Our focus remains on commercializing this technology.


11



MTeq, a PX solution for mud pumping applications: Our MTeq technology isolates and preserves costly mud pumps by re-routing hostile drilling mud from these critical pumps, and ultimately enables a more efficient pumping model. These mud pumps will process only clean fluid, which leads to reduced repairs and maintenance costs and reduced capital costs by extending pump life expectancy and eliminating redundant capital equipment. Our MTeq technology is currently in the R&D stage and we are actively working towards progressing this technology. We designed the MTeq during late 2016 and early 2017 and completed building the first prototype in December 2017.

Midstream and Downstream Sectors

IsoBoost & IsoGen, turbocharger solutions, for gas processing & pipeline applications: Within the gas processing and pipeline pressure down cycle, the IsoBoost and IsoGen technology enables the recovery of pressure energy in the fluid flows either through the exchange of pressure within the application or by converting it to electricity. Our technology enables gas processing plant and pipeline owners and operators to achieve immediate and long-term energy savings with little or no operational disruption. Our IsoBoost is comprised of hydraulic turbochargers and related controls and automation systems. The IsoBoost solution enables oil & gas operators to capture and use wasted hydraulic pressure energy within the acid gas removal process, acting like a pump that is powered by hydraulic pressure that would otherwise be discarded through a control valve. Our IsoGen is comprised of hydraulic turbines, generators, and related controls and automation systems. The IsoGen enables oil & gas operators to generate electricity from the hydraulic energy in high-pressure fluid flows, either within the acid gas removal process in gas processing or at pipeline choke stations.

Customers

We license, lease or sell our oil and gas products to oil field service companies, international oil companies (“IOC”), national oil companies (“NOC”), exploration and production companies (“E&P”), OEMs and EPC firms.

Oilfield Service Companies

OFS companies provide the infrastructure, equipment, intellectual property, and services needed by the oil & gas industry to explore for, extract, and transport crude oil and natural gas. OFS hydraulic fracturing and mud pumping operators face significant pressure to reduce costs as oil & gas companies curtail capital expenditures and seek operational efficiencies in response to lower commodity prices.

In 2014, we entered into a strategic partnership with Liberty Oil Field Services (“Liberty”) to pilot and conduct field trials with the VorTeq. Through this agreement, Liberty has the rights to lease up to twenty VorTeq missiles for a period of up to five years following commercialization. In 2015, we entered into a 15-year license agreement with Schlumberger Technology Corporation (the “VorTeq Licensee”) for the exclusive, worldwide right to use the VorTeq for hydraulic fracturing onshore operations. The license agreement provides a carve out for Liberty’s contractual rights to utilize the VorTeq. We are currently working with the VorTeq Licensee and Liberty to commercialize the VorTeq technology.

As the MTeq technology matures, the Company intends to evaluate the best potential distribution method for the technology, which may include long term licensing partnerships with OFS companies that specialize in drilling wells or OEMs that supply or lease equipment to market participants.

Gas Processing & Pipeline Operators

We have contracted and delivered oil & gas solutions to customers in North America, Asia, and the Middle East for use in gas processing applications. Our target market consists of gas processing plants, pipeline substations and ammonia plants worldwide. Our IsoGen solution has been installed in a major gas processing plant in the Middle East.

In 2016, we received our first major purchase order for multiple units of our IsoBoost solution for integration into a major gas processing plant under construction in the Middle East. We completed and shipped the initial units to the Middle East in fourth quarter of 2018. In April 2017, we entered into a 10-year licensing agreement with Alderley FZE for our IsoBoost & IsoGen technologies in gas processing and pipeline applications within the countries of the Gulf Cooperation Council (“GCC”), as well as Iraq and Iran to the extent international sanctions and laws permit.

Competition

The landscape for our technology within the oil & gas market is competitive as the industry is continuously seeking ways to reduce costs and extend the life of assets used in the production or transportation of hydrocarbons. As demand for our products increases, we expect competition to intensify.

We believe our VorTeq technology represents a competitive advantage over existing missile manifold technology because our solution re-routes abrasive proppant away from high-pressure pumps and will provide OFS operators the option to transition to more robust, longer lived, centrifugal pumps thereby further decreasing operating and capital costs. While our VorTeq replaces a traditional manifold, the competitors to our VorTeq are the high-pressure frac pump manufacturers. There are a multitude of these pump manufacturers, including Gardner Denver, Inc., FMC Technologies, the Weir Group, Stewart & Stevenson and Forum Energy Technologies.

Similar to the VorTeq, the MTeq enhances the useful life of mud pumps and consumable pump components used in land drilling by re-routing the hostile drilling mud away from the high-pressure pumps and OFS operators have the option to transition to more robust, longer life, centrifugal pumps thereby further decreasing operating and capital costs. The competition to the MTeq is a more robust mud pump or more durable mud pump components. The primary manufacturers of mud pumps are National Oilwell Varco, Inc., Gardner Denver, Inc. and Cameron International Corporation.

Several companies manufacture competitive technology to the IsoGen, which primarily consists of reverse running pumps (also called hydraulic power recovery turbines or HPRTs) and perform a basic form of energy recovery. Manufacturers of reverse running pumps include, but are not limited to, Flowserve, Sulzer Pumps, Ltd., and Shin Nippon Machinery. Several companies manufacture hydraulic turbochargers, which could eventually develop into competitive technology to the IsoBoost. However, none of these companies that manufacture turbochargers have significant experience within gas processing. In order to utilize a turbocharger in gas processing, expertise is required to validate the system level design and integration within a gas processing application.

Sales and Marketing

In the oil & gas market, we target OFSs, IOCs, NOCs, E&Ps, OEMs or EPCs on behalf of oil producers and chemical producers who have applications for our solutions and services. We endeavor to limit capital sales into the oil & gas market, thereby minimizing installation and distribution costs, as well as associated sales and marketing expenses. As a result, our primary go-to-market strategy in the oil & gas market is through technology licensing as outlined in the Customer section of this overview.

A significant portion of our revenue is from outside of the U.S. Additional segment and geographical information regarding our product revenue is included in Note 14, “Geographical Information and Concentrations” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K.

Operations

Our oil & gas product manufacturing, assembly, and testing has been historically managed through our operations in Ireland. In October 2018, these functions were transitioned to the U.S. branch of our Ireland operating company, which is resident in Malta. To produce our oil & gas products, we utilize multiple supply chain partners, in addition to our San Leandro manufacturing facility. We complete critical machining, assembly, and testing operations in-house to protect the proprietary nature of our manufacturing methods and product designs and to maintain premium quality standards. Our Ireland operations has also historically been responsible for overseeing the commercialization of the VorTeq. Likewise, in October 2018, this responsibility was transitioned to the U.S. branch of our Ireland operating company, which is tax resident in Malta.

Oil & gas field activities are conducted by our field operations organization, which also provides support to R&D activities leading to VorTeq and MTeq commercialization.

In January 2019, we signed a long-term lease for a new facility near Houston, Texas. This facility will consolidate our Texas Oil & Gas operations and allow us to test our VorTeq and MTeq technologies at scale and in real world conditions on a regular, uninterrupted basis. The facility will also house equipment to manufacture, machine, inspect and test tungsten carbide components in support of R&D and eventual commercialization.

Seasonality

In our Oil & Gas segment, we do not currently have enough history to determine seasonal revenue patterns.


Research and Development

Energy Recovery’s focus on R&D is a key driver of the company’s future evolution. When developing products, we seek four distinct process criteria: (1) high rates of fluid flow; (2) large pressure differentials; (3) hostile fluids; and (4) high degrees of capital intensity, specifically in the form of pumping and/or compression assets. Using these criteria, our product development strategy is to identify fluid flow applications where equipment is being destroyed or adversely affected and/or where pressure energy is being wasted. We maintain a product development road map, which guides R&D resource allocation across all business units. Our R&D team guides products through defined development stages with structured toll-gate reviews throughout the process.

The Company has invested significantly in R&D to support our product development strategy and has grown its R&D headcount by 45 percent since 2013. We maintain advanced testing capabilities at our headquarters in San Leandro, California and are building new testing facilities for oil & gas applications in Texas.

Our engineers specialize in a range of technical fields spanning the Company’s core engineering competencies of fluid mechanics and aerodynamics, solid mechanics with expertise in computational fluid dynamics and finite element analysis, bearings design (roller-element, hydrostatic, and hydrodynamic), multi-phase flow, dynamics and controls, acoustics and vibrations, tribology, material science and coatings, pumps and turbines, aircraft engines, turbomachines, and rotating machinery.

We have invested in advanced numerical modeling and analytical tools that allow for 3D, multi-phase, multi-physics, and multi-scale computational fluid dynamics and fluid structure interactions. Leading-edge modeling and analytical techniques coupled with extensive experimental capabilities allow us to further refine our existing water and oil and gas technologies, as well as develop new derivatives of the PX pressure exchanger for complex systems and applications.

We have advanced testing capabilities in our San Leandro facility to test our PX Pressure Exchanger, Turbocharger, and pump technologies. We are building new testing facilities in Texas that will allow us to test our oil & gas products at full scale. In 2018, we made a sizable investment in high pressure frac equipment such as frac pumps, blenders, and other equipment to bolster our testing capabilities in Texas to advance our VorTeq and MTeq solutions.

Today our R&D investments are focused on (1) commercialization of our VorTeq and MTeq solutions; (2) advances to our existing PX pressure exchanger, turbocharger, and pump technologies to better service our water end markets; (3) development of new pump technologies in support of our water business; and (4) fundamental research into new applications of our PX pressure exchanger technology in existing and new verticals.
Intellectual Property

We seek patent protection for new technologies, inventions, and improvements that are likely to be incorporated into our solutions. We rely on patents, trade secret laws, and contractual safeguards to protect the proprietary tooling, processing techniques, and other know-how used in the production of our solutions. We have a robust intellectual property portfolio consisting of U.S. and international issued patents as well as pending patent applications.

We have registered the following trademarks with the United States Patent and Trademark office: “ERI,” “PX,” “PX Pressure Exchanger,” “Pressure Exchanger,” the Energy Recovery logo, “Making Desalination Affordable,” “IsoBoost,” and “IsoGen.” Applications are pending for “VorTeq” and “MTeq.” We have also applied for and received registrations in international trademark offices.

Item 1A — Risk Factors

The following discussion sets forth what management currently believes could be the most significant risks and uncertainties that could impact our businesses, results of operations, and financial condition. Other risks and uncertainties, including those not currently known to the Company or its management, could also negatively impact our businesses, results of operations, and financial conditions. Accordingly, the following should not be considered a complete discussion of all of the risks and uncertainties the Company may face. We may amend or supplement these risk factors from time to time in other reports we file with the SEC.

Risk Related to our Water Segment

Our Water Segment depends on the construction of new desalination plants for revenue, and as a result, our operating results have experienced, and may continue to experience, significant variability due to volatility in capital spending, availability of project financing, and other factors affecting the water desalination industry.

We currently derive the majority of our revenue from sales of products and services used in desalination plants for municipalities, hotels, mobile containerized desalination solutions, resorts, and agricultural operations in dry or drought-ridden regions of the world. The demand for our Water segment products may decrease if the construction of desalination plants declines for political, economic, or other factors, especially in these dry or drought-ridden regions. Other factors that could affect the number and capacity of desalination plants built or the timing of their completion, include the availability of required engineering and design resources; a weak global economy; shortage in the supply of credit and other forms of financing; changes in government regulation, permitting requirements, or priorities; and reduced capital spending for desalination. Each of these factors could result in reduced or uneven demand for our Water segment products. Pronounced variability or delays in the construction of desalination plants or reductions in spending for desalination, could negatively impact our Water segment sales and revenue, which in turn could have an adverse effect on our entire business, financial condition, or results of operations and make it difficult for us to accurately forecast our future sales and revenue.

Our Water segment faces competition from a number of companies that offer competing energy recovery and pump solutions. If any one of these companies produces superior technology or offers more cost-effective products, our competitive position in the market could be harmed and our profits may decline.

The market for ERD and pumps for desalination plants is competitive and evolving. We expect competition, especially competition on price, to persist and intensify as the desalination market grows and new competitors enter the market. Some of our current and potential competitors may have significantly greater financial, technical, marketing, and other resources; longer operating histories; or greater name recognition. They may also have more extensive products and product lines that would enable them to offer multi-product or packaged solutions as well as competing products at lower prices or with other more favorable terms and conditions. As a result, our ability to sustain our market share may be adversely impacted, which would affect our business, operating results, and financial condition. In addition, if one of our competitors were to merge or partner with another company, the change in the competitive landscape could adversely affect our continuing ability to compete effectively.

If we are unable to collect unbilled receivables, which are caused in part by holdback provisions, our operating results could be adversely affected.

Our contracts with large engineering, procurement, and construction firms generally contain holdback provisions that typically delay final installment payments for our products by up to 24 months, after the product has been shipped and revenue has been recognized. Generally, 10% or less of the revenue we recognize pursuant to our customer contracts is subject to such holdback provisions and is accounted for as contract assets. Such holdbacks may result in relatively high unbilled receivables. If we are unable to collect these performance holdbacks, our results of operations would be adversely affected.


16



We depend on a limited number of suppliers for some of our components. If our suppliers are not able to meet our demand and/or requirements, our business could be harmed.

We rely on a limited number of suppliers for vessel housings, stainless steel ports, alumina powder, and tungsten carbide for our portfolio of PX ERDs and stainless steel castings and components for our turbochargers and pumps. Our reliance on a limited number of manufacturers for these supplies involves several risks, including reduced control over delivery schedules, quality assurance, manufacturing yields, production costs, and lack of guaranteed production capacity or product supply. We do not have long-term supply agreements with these suppliers but secure these supplies on a purchase order basis. Our suppliers have no obligation to supply products to us for any specific period, in any specific quantity, or at any specific price, except as set forth in a particular purchase order. Our requirements may represent a small portion of the total production capacities of these suppliers, and our suppliers may reallocate capacity to other customers, even during periods of high demand for our products. We have in the past experienced, and may in the future experience, product quality issues and delivery delays with our suppliers due to factors such as high industry demand or the inability of our vendors to consistently meet our quality or delivery requirements. If our suppliers were to cancel or materially change their commitments to us or fail to meet quality or delivery requirements needed to satisfy customer orders for our products, we could lose time-sensitive customer orders, be unable to develop or sell our products cost-effectively or on a timely basis, if at all, and have significantly decreased revenue, which could harm our business, operating results, and financial condition. We may qualify additional suppliers in the future, which would require time and resources. If we do not qualify additional suppliers, we may be exposed to increased risk of capacity shortages due to our dependence on current suppliers.

Risk Related to our Oil & Gas Segment

We may not be able to successfully commercialize the VorTeq.

In October 2015, we entered into the VorTeq License Agreement with the VorTeq Licensee, which provides the VorTeq Licensee with exclusive worldwide rights to our VorTeq technology for hydraulic fracturing onshore applications. Once the VorTeq is commercialized, the VorTeq Licensee will begin paying ongoing recurring royalty fees to us for the VorTeq technology. In order to commercialize the VorTeq, the VorTeq License Agreement provides, among other things, that we successfully meet certain specified milestones against key performance indicators set forth in the license agreement. The VorTeq is a relatively new technology and the hydraulic fracturing process is extremely complex, which presents a wide range of technological challenges for us. If we are unable to successfully solve these challenges and, as a result, fail to meet the milestones, we may not be able to successfully commercialize the VorTeq. In that circumstance, we will not receive any royalty payments from the VorTeq Licensee, which could have an adverse effect on our entire business, financial condition, or results of operation.

If the VorTeq Licensee fails to adopt the VorTeq, for any reason, we may not receive royalty payments or be able to successfully commercialize the VorTeq.

The successful commercialization of the VorTeq depends heavily on the VorTeq Licensee’s support and ultimate adoption of the technology. If the VorTeq Licensee fails to adopt the VorTeq, for any reason, we may not be able to successfully commercialize the VorTeq with the VorTeq Licensee and consequently, we may not receive any royalties under the VorTeq License Agreement. In addition, we may not be able to find a suitable replacement for the VorTeq Licensee or be able to negotiate royalties similar to those contained in the VorTeq License Agreement or to commercialize the VorTeq at all. Failure to commercialize the VorTeq could have an adverse effect on our entire business, financial condition, or results of operation.

We may not meet the key performance indicators necessary to meet the two milestones in the VorTeq License Agreement.

The VorTeq License Agreement calls for certain milestone key performance indicators that if met will result in payments to the Company of $25 million for each of two milestones. Achievement of these milestones is uncertain, and while we believe we can meet the milestones, if we are unable to do so, the milestone payments will be delayed until such time as the milestones are met or may not be earned and received at all. Failure to meet said milestones may also jeopardize commercialization and the rate of adoption of our VorTeq.


17



We may not be able to successfully complete early stage testing of the MTeq, enter into a long term licensing agreement for the MTeq or fail to commercialize the MTeq.

We introduced the MTeq in 2017 and entered into a strategic early stage testing agreement in the second quarter of 2017. Like the VorTeq, we intend to find a long-term licensing partner for the MTeq and to ultimately commercialize the MTeq. Even if early stage testing proves to be successful, we may not be able to identify a licensing partner for the technology to assist us in bringing the MTeq solution to the market. If we were able to enter into such a licensing agreement, we may still fail to produce a viable commercialized solution given the complex and extreme conditions found in mud pumping, which present a wide range of technological challenges for us. If we are unable to successfully complete early stage testing, fail to locate and successfully negotiate a licensing or similar agreement with a long-term partner, or fail to solve any of the technological challenges, we may not be able to successfully commercialize the MTeq, which could have an adverse effect on our entire business, financial condition, or results of operation.

Our Oil & Gas segment may be impacted by prolonged deflation in global oil prices which may cause delays or cancellations of projects by Oil & Gas segment customers, negatively affecting the rate of our market penetration and consequently our revenue and profitability.

A deflationary oil environment may delay and even stall adoption and deployment of our products within our Oil & Gas segment including but not limited to the VorTeq as licensed for onshore applications by the VorTeq Licensee. Emerging market economies, those dependent on commodity exports, and especially those for whom oil exports make up a significant percent of total exports, may be unable to retrofit or expand their oil exploration, production, and gas processing infrastructure thus negatively impacting our addressable market and future revenue. Additionally, oil price deflation may continue to lead to widespread liquidity and insolvency issues for exploration, production, and processing customers, which may negatively affect our addressable markets and therefore our financial performance.

Risk Related to our Entire Business

Our diversification into new fluid flow markets, such as oil & gas, may not be successful

We have made a substantial investment in research, development, and sales to execute on our diversification strategy into fluid flow markets such as oil & gas and chemical processing. While we see diversification as core to our growth strategy, there is no guarantee that we will be successful in our efforts. Our model for growth is based in part on our ability to initiate and embrace disruptive technology trends, to enter new markets, both in terms of geographies and product areas, and to drive broad adoption of the products and services that we develop and market. Any inability to execute this model for growth could damage our reputation, limit our growth, and negatively affect our operation results. For example, while we believe that our products will enable gas processing plant operators to operate at a high level of energy efficiency with minimal downtime, we may be subject to warranty claims if customers of these offerings experience significant downtimes or failures for which our warranty reserves may be inadequate given the lack of historical failure rates associated with new product introductions. We also could be subject to damage claims based on our products, which we may not be able to properly insure. In addition, profitability, if any, in new industrial verticals may be lower than in our Water Segment, and we may not be sufficiently successful in our diversification efforts to recoup investments.

Our operating results may fluctuate significantly, making our future operating results difficult to predict and causing our operating results to fall below expectations.

Our operating results may fluctuate due to a variety of factors, many of which are outside of our control.

We have experienced significant fluctuations in revenue from quarter-to-quarter and year-to-year, and we expect such fluctuations to continue. In addition, in the past, customer buying patterns led to a significant portion of our sales occurring in the fourth quarter. This presents the risk that delays, cancellations, or other adverse events in the fourth quarter could have a substantial negative impact on annual results. As a result, comparing our operating results on a period-to-period basis may not be meaningful. Since it is difficult for us to anticipate our future results, in the event our revenue or operating results fall below the expectations of investors or securities analysts, our stock price may decline.


18



Our sales cycles can be long and unpredictable, and our sales efforts require considerable time and expense. As a result, our sales are difficult to predict and may vary substantially from quarter to quarter, which may cause our operating results to fluctuate.

Our sales efforts involve substantial education of our current and prospective customers about the use and benefits of our energy recovery products. This education process can be time-consuming and typically involves a significant product evaluation process which is particularly pronounced when dealing with product introduction into new fluid flow industrial verticals. In our Water segment, the sales cycle for our OEM customers, which are involved with smaller desalination plants, averages one to 12 months. The Water segment sales cycle for our international engineering, procurement, and construction firm customers, which are involved with larger desalination plants, ranges from 16 to 36 months. These long sales cycles make quarter-by-quarter revenue predictions difficult and results in our expending significant resources well in advance of orders for our products.

Our business entails significant costs that are fixed or difficult to reduce in the short term while demand for our products is variable and subject to fluctuation, which may adversely affect our operating results.

Our business requires investments in facilities, equipment, research and development, and training that are either fixed or difficult to reduce or scale in the short term. At the same time, the market for our products is variable and has experienced downturns due to factors such as economic recessions, increased precipitation, uncertain global financial markets, and political changes, many of which are outside of our control. During periods of reduced product demand, we may experience higher relative costs and excess manufacturing capacity, resulting in high overhead and lower gross profit margins while causing cash flow and profitability to decline. Similarly, although we believe that our existing manufacturing facilities are capable of meeting current demand and demand for the foreseeable future, the continued success of our business depends on our ability to expand our manufacturing, research and development, and testing facilities to meet market needs. If we are unable to respond timely to an increase in demand, our revenue, gross profit margin, net income, and cash flow may be adversely affected.

Parts of our inventory may become excess or obsolete, which would increase our cost of revenues.

Inventory of raw materials, parts, components, work in-process, or finished products may accumulate, and we may encounter losses due to a variety of factors, including technological change in the water desalination and oil & gas industries that result in product changes; long delays in shipment of our products or order cancellations; our need to order raw materials that have long lead times and our inability to estimate exact amounts and types of items needed, especially with regard to the configuration of our high-efficiency pumps and IsoBoost and IsoGen systems; and cost reduction initiatives resulting in component changes within the products.

In addition, we may from time to time purchase more inventory than is immediately required in order to shorten our delivery time in case of an anticipated increase in demand for our products. If we are unable to forecast demand for our products with a reasonable degree of certainty and our actual orders from our customers are lower than these forecasts, we may accumulate excess inventory that we may be required to write off, and our business, financial condition, and results of operations could be adversely affected.

We may not generate positive returns on our research and development strategy.

Developing our products is expensive and the investment in product development may involve a long payback cycle. For the years ended December 31, 2018, 2017 and 2016, our R&D expenses were $17.0 million, or approximately 23% of our total revenue, $13.4 million, or approximately 19% of our total revenue, and $10.1 million, or approximately 18% of our total revenue, respectively. We believe one of our greatest strengths lies in our innovation and our product development efforts. By investing in R&D, we believe we are well positioned to continue to execute on our product strategy, take into consideration our customers’ cost and efficiency sensitivities and take advantage of other market opportunities. We expect that our results of operations may be impacted by the timing and size of these investments. In addition, these investments may take several years to generate positive returns, if ever.


19



We are subject to risks related to product defects, which could lead to warranty claims in excess of our warranty provision or result in a significant or a large number of warranty or other claims in any given year.

We provide a warranty for certain products for a period of 18 to 30 months and provide up to a five-year warranty for the ceramic components of our PX-branded products. We test our products in our manufacturing facilities through a variety of means; however, there can be no assurance that our testing will reveal latent defects in our products, which may not become apparent until after the products have been sold into the market. The testing may not replicate the harsh, corrosive, and varied conditions of the desalination and other plants in which they are installed. It is also possible that components purchased from our suppliers could break down under those conditions. Certain components of our turbochargers and pumps are custom-made and may not scale or perform as required in production environments. Accordingly, there is a risk that we may have significant warranty claims or breach supply agreements due to product defects. We may incur additional cost of revenue if our warranty provisions are not sufficient to cover the actual cost of resolving issues related to defects in our products. If these additional expenses are significant, they could adversely affect our business, financial condition, and results of operations.

Business interruptions may damage our facilities or those of our suppliers.

Our operations and those of our suppliers may be vulnerable to interruption by fire, earthquake, flood, and other natural disasters, as well as power loss, telecommunications failure, and other events beyond our control. Our facilities in California are located near major earthquake faults and have experienced earthquakes in the past. If a natural disaster occurs, our ability to conduct our operations could be seriously impaired, which could harm our business, financial condition, results of operations, and cash flows. We cannot be sure that the insurance we maintain against general business interruptions will be adequate to cover all of our losses.

If we are unable to protect our technology or enforce our intellectual property rights, our competitive position could be harmed, and we could be required to incur significant expenses to enforce our rights.

Our competitive position depends on our ability to establish and maintain proprietary rights in our technology and to protect our technology from copying by others. We rely on trade secret, patent, copyright, and trademark laws, as well as confidentiality agreements with employees and third parties, all of which may offer only limited protection. We hold a number of U.S. and counterpart international patents, and when their terms expire, we could become more vulnerable to increased competition. The protection of our intellectual property in some countries may be limited. While we have expanded our portfolio of patent applications, we do not know whether any of our pending patent applications will result in the issuance of patents or whether the examination process will require us to narrow our claims, and even if patents are issued, they may be contested, circumvented, or invalidated. Moreover, while we believe our issued patents and patent pending applications are essential to the protection of our technology, the rights granted under any of our issued patents or patents that may be issued in the future may not provide us with proprietary protection or competitive advantages, and as with any technology, competitors may be able to develop similar or superior technologies now or in the future. In addition, our granted patents may not prevent misappropriation of our technology, particularly in foreign countries where intellectual property laws may not protect our proprietary rights as fully as those in the United States. This may render our patents impaired or useless and ultimately expose us to currently unanticipated competition. Protecting against the unauthorized use of our products, trademarks, and other proprietary rights is expensive, difficult, and in some cases, impossible. Litigation may be necessary in the future to enforce or defend our intellectual property rights or to determine the validity and scope of the proprietary rights of others. Intellectual property litigation could result in substantial costs and diversion of management resources, either of which could harm our business.


20



Claims by others that we infringe their proprietary rights could harm our business.

Third parties could claim that our technology infringes their intellectual property rights. In addition, we or our customers may be contacted by third parties suggesting that we obtain a license to certain of their intellectual property rights that they may believe we are infringing. We expect that infringement claims against us may increase as the number of products and competitors in our market increases and overlaps occur. In addition, to the extent that we gain greater visibility, we believe that we will face a higher risk of being the subject of intellectual property infringement claims. Any claim of infringement by a third party, even those without merit, could cause us to incur substantial costs defending against the claim and could distract management from our business. Furthermore, a party making such a claim, if successful, could secure a judgment that requires us to pay substantial damages. A judgment against us could also include an injunction or other court order that could prevent us from offering our products. In addition, we might be required to seek a license for the use of such intellectual property, which may not be available on commercially reasonable terms, or at all. Alternatively, we may be required to develop non-infringing technology, which could require significant effort and expense and may ultimately not be successful. Any of these events could seriously harm our business. Third parties may also assert infringement claims against our customers. Because we generally indemnify our customers if our products infringe the proprietary rights of third parties, any such claims would require us to initiate or defend protracted and costly litigation on their behalf in one or more jurisdictions, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of our customers.

We are currently involved in legal proceedings, and may be subject to additional future legal proceedings, that may result in material adverse outcomes.

In addition to the intellectual property litigation risks discussed above, we are presently involved, and may become involved in the future, in various commercial and other disputes as well as related claims and legal proceedings that arise from time to time in the course of our business. See Note 16, Litigation,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for information about certain legal proceedings in which we are involved. Our current legal proceedings and any future lawsuits to which we may become a party are and will likely be expensive and time consuming to investigate, defend and resolve, and will divert our management’s attention. Any litigation to which we are a party may result in an onerous or unfavorable judgment that may not be reversed upon appeal or in payments of substantial monetary damages or fines, or we may decide to settle lawsuits on similarly unfavorable terms, which could have an adverse effect on our business, financial condition, or results of operations.

Our global operations expose us to risks and challenges associated with conducting business internationally, and our results of operations may be adversely affected by our efforts to comply with the laws of other countries, as well as U.S. laws which apply to international operations, such as the Foreign Corrupt Practices Act (FCPA) and U.S. export control laws.

We operate on a global basis with offices or activities in Europe, Africa, Asia, South America, and North America. We face risks inherent in conducting business internationally, including compliance with international and U.S. laws and regulations that apply to our international operations. These laws and regulations include tax laws, anti-competition regulations, import and trade restrictions, export control laws, and laws which prohibit corrupt payments to governmental officials or certain payments or remunerations to customers, including the U.S. Foreign Corrupt Practices Act (“FCPA”) or other anti-corruption laws that have recently been the subject of a substantial increase in global enforcement. Many of our products are subject to U.S. export law restrictions that limit the destinations and types of customers to which our products may be sold, or require an export license in connection with sales outside the United States. Given the high level of complexity of these laws, there is a risk that some provisions may be inadvertently or intentionally breached, for example through fraudulent or negligent behavior of individual employees, our failure to comply with certain formal documentation requirements, or otherwise. Also, we may be held liable for actions taken by our local dealers and partners. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions or conditions on the conduct of our business. Any such violations could include prohibitions or conditions on our ability to offer our products in one or more countries and could materially damage our reputation, our brand, our business, and our operating results. In addition, we operate in many parts of the world that have experienced significant governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices. We may be subject to competitive disadvantages to the extent that our competitors are able to secure business, licenses, or other preferential treatment by making payments to government officials and others in positions of influence or through other methods that relevant law and regulations prohibit us from using. Our success depends, in part, on our ability to anticipate these risks and manage these difficulties. These factors or any combination of these factors may adversely affect our revenue or our overall financial performance.


21



Uncertainty in the global geopolitical landscape may impact our operations outside the United States.

There is uncertainty as to the position the United States will take with respect to world affairs. This uncertainty may include such issues as U.S. support for existing treaty and trade relationships with other countries, including, notably, China. This uncertainty, together with other recent key global events (such as recently enacted currency control regulations and tariff regimes in or against China, the continuing uncertainty arising from the Brexit referendum in the United Kingdom as well as ongoing terrorist activity, and potential hostilities in the Middle East) may adversely impact (i) the ability or willingness of non-U.S. companies to transact business in the United States, including with us, (ii) our ability to transact business in other countries, including the Middle East, where many of the water mega-projects are planned, (iii) regulation and trade agreements affecting U.S. companies, (iv) global stock markets (including The Nasdaq Global Market on which our common shares are traded), and (v) general global economic conditions. All of these factors are outside of our control, but may nonetheless cause us to adjust our strategy in order to compete effectively in global markets.

Acts of War or Terrorism
 
Threats or acts of war or terrorism can adversely affect our business. Terrorist attacks in the United States, Europe and in other countries and continuing hostilities in the Middle East and elsewhere have created significant instability and uncertainty in the world. These and future events may have a material adverse effect on world financial markets as well as the water industry, as many large existing and planned water desalination plants are located in the Middle East. In addition, threats or acts of war or terrorism can cause our customers to curtail their purchase of our products. These factors or any combination of these factors may adversely affect our revenue or our overall financial performance.

The U.S. Congress and Trump Administration may make substantial changes to fiscal, political, regulation and other federal policies that may adversely affect our business, financial condition, operating results and cash flows.

Changes in general economic or political conditions in the United States or other regions could adversely affect our business. There have been and may be significant changes in, and uncertainty with respect to, legislation, regulation and government policy. While it is not possible to predict whether and when any such changes will occur, changes at the local, state or federal level could impact our business. Specific legislative and regulatory proposals that could have a material impact on us include, but are not limited to, modifications to international trade policy; public company reporting requirements; and environmental regulation.

Additionally, on July 6, 2018, the Trump Administration imposed 25% tariffs on a variety of imports from China, including certain components imported into the U.S. for our manufacturing activities. The Administration subsequently imposed tariffs on two additional lists of products from China; the first of these additional lists involves 25% tariffs and the second list imposes 10% tariffs, which were originally scheduled to increase to 25% on January 1, 2019. On November 19, 2018, the U.S. Bureau of Industry and Security proposed export control rules on emerging technologies for public comment.

China responded to the multiple U.S. tariff lists by announcing several lists of products from the U.S. that are subject to additional tariffs upon import to China. The first round of Chinese retaliatory tariffs went into effect on July 6, 2018, and a second set was implemented on August 23, 2018. Our products are not impacted by these tariffs. A third group of items subject to 5 to 10% tariff went into effect on September 24, 2018, which includes our PX Pressure Exchanger, Turbocharger, and pump products. On December 2, 2018, the U.S. and China agreed to refrain from increasing tariffs or imposing new tariffs until March 1, 2019.  On February 24, 2019, President Trump announced via Twitter that he will be delaying increases in tariffs due to recent progress in trade talks.

We cannot predict what actions may ultimately be taken with respect to tariffs or trade relations between the United States and other countries, what products may be subject to such actions, or what actions may be taken by the other countries in retaliation. Accordingly, it is difficult to predict how such actions may impact our business, or the business of our customers. Our business operations, as well as the businesses of our customers on which we are substantially dependent, are located in various countries at risk for escalating trade disputes, including the United States and China. Any resulting trade wars could have a significant adverse effect on world trade and could adversely impact our revenues, gross margins and business operations.

22




Regulations related to conflict minerals could adversely impact our business.

The Dodd-Frank Wall Street Reform and Consumer Protection Act contains provisions to improve transparency and accountability concerning the supply of certain minerals, known as conflict minerals, originating from the Democratic Republic of Congo (“DRC”) and adjoining countries. As a result, in August 2012, the SEC adopted annual disclosure and reporting requirements for those companies who use conflict minerals mined from the DRC and adjoining countries in their products. Based on our purchasing policy and supplier selection, it is considered unlikely that any conflict minerals are used in the manufacturing of our products. Nevertheless, we are continuing reasonable country of origin inquiry and have implemented a program of due diligence on the source and chain of custody for conflict minerals. There are costs associated with complying with these disclosure requirements, including loss of customers and potential changes to products, processes, or sources of supply. The implementation of these rules could adversely affect the sourcing, supply, and pricing of materials used in our products. As there may be only a limited number of suppliers offering “conflict free” minerals, we cannot be sure that we will be able to obtain necessary materials from such suppliers in sufficient quantities or at competitive prices. Also, we may face reputational challenges if we determine that certain of our products contain minerals not determined to be conflict-free or if we are unable to sufficiently verify the origins for all conflict minerals used in our products through the procedures we have implemented.

We may have risks associated with security of our information technology systems.

We make significant efforts to maintain the security and integrity of our information technology systems and data. Despite significant efforts to create security barriers to such systems, it is virtually impossible for us to entirely mitigate this risk. There is a risk of industrial espionage, cyber-attacks, misuse or theft of information or assets, or damage to assets by people who may gain unauthorized access to our facilities, systems, or information. Such cybersecurity breaches, misuse, or other disruptions could lead to the disclosure of confidential information, improper usage and distribution of our intellectual property, theft, manipulation and destruction of private and proprietary data, and production downtimes. Although we actively employ measures to prevent unauthorized access to our information systems, preventing unauthorized use or infringement of our rights is inherently difficult. These events could adversely affect our financial results and any legal action in connection with any such cybersecurity breach could be costly and time-consuming and may divert management’s attention and adversely affect the market’s perception of us and our products. In addition, we must frequently expand our internal information system to meet increasing demand in storage, computing and communication, which may result in increased costs. Our internal information system is expensive to expand and must be highly secure due to the sensitive nature of our customers’ information that we transmit. Building and managing the support necessary for our growth places significant demands on our management and resources. These demands may divert these resources from the continued growth of our business and implementation of our business strategy.

We may have risks associated with our international tax optimization structure

In 2015, we implemented an international tax optimization structure.  While the Company continues to conclude that uncertain tax positions are unlikely, it is possible that the international tax structure could be examined by the Internal Revenue Service in the U.S. and/or the Tax Authorities in Ireland, and it is possible that such an examination could result in an unfavorable impact on us.


The enactment of legislation implementing changes in taxation of international business activities, the adoption of other corporate tax reform policies, or changes in tax legislation or policies could materially impact our financial position and results of operations.

Corporate tax reform, base-erosion efforts and tax transparency continue to be high priorities in many tax jurisdictions where we have business operations. As a result, policies regarding corporate income and other taxes in numerous jurisdictions are under heightened scrutiny and tax reform legislation is being proposed or enacted in a number of jurisdictions. For example, on December 22, 2017, President Trump signed into law “H.R.1”, known as the “Tax Cuts and Jobs Act”, (the “Tax Act”), which significantly changes existing U.S. tax laws.


23



In addition, many countries are beginning to implement legislation and other guidance to align their international tax rules with the Organisation for Economic Co-operation’s Base Erosion and Profit Shifting recommendations and action plan that aim to standardize and modernize global corporate tax policy, including changes to cross-border tax, transfer-pricing documentation rules, and nexus-based tax incentive practices. As a result of the heightened scrutiny of corporate taxation policies, prior decisions by tax authorities regarding treatments and positions of corporate income taxes could be subject to enforcement activities, and legislative investigation and inquiry, which could also result in changes in tax policies or prior tax rulings. Any such changes in policies or rulings may also result in the taxes we previously paid being subject to change.

Due to the scale of our international business activities any substantial changes in international corporate tax policies, enforcement activities or legislative initiatives may materially and adversely affect our business, the amount of taxes we are required to pay and our financial condition and results of operations generally.

If we need additional capital to fund future growth, it may not be available on favorable terms, or at all.

Our primary source of cash historically has been customer payments for our products and services and proceeds from the issuance of common stock. This has funded our operations and capital expenditures. We may require additional capital from equity or debt financing in the future to fund our operations or respond to competitive pressures or strategic opportunities, such as a potential acquisition or the expansion of operations. We may not be able to secure such additional financing on favorable terms or at all. The terms of additional financing may place limits on our financial and operational flexibility. If we raise additional funds through further issuances of equity, convertible debt securities, or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of our company, and any new securities that we issue could have rights, preferences, or privileges senior to those of existing or future holders of our common stock. If we are unable to obtain necessary financing on terms satisfactory to us, if and when we require it, our ability to grow or support our business and to respond to business challenges or opportunities could be significantly limited.

We may seek to expand through acquisitions of and investments in other businesses, technologies, and assets. These acquisition activities may be unsuccessful or divert management’s attention.

We may consider strategic and complementary acquisitions of and investments in other businesses, technologies, and assets, and such acquisitions or investments are subject to risks that could affect our business, including risks related to:

the necessity of coordinating geographically disparate organizations;
implementing common systems and controls;
integrating personnel with diverse business and cultural backgrounds;
integrating acquired research and manufacturing facilities, technology and products;
combining different corporate cultures and legal systems;
unanticipated expenses related to integration, including technical and operational integration;
increased costs and unanticipated liabilities, including with respect to registration, environmental, health and safety matters, that may affect sales and operating results;
retaining key employees;
obtaining required government and third-party approvals;
legal limitations in new jurisdictions;
installing effective internal controls and audit procedures;
issuing common stock that could dilute the interests of our existing stockholders;
spending cash and incurring debt;
assuming contingent liabilities; and
creating additional expenses.

We may not be able to identify opportunities or complete transactions on commercially reasonable terms, or at all, or actually realize any anticipated benefits from such acquisitions or investments. Similarly, we may not be able to obtain financing for acquisitions or investments on attractive terms. If we do complete acquisitions, we cannot ensure that they will ultimately strengthen our competitive or financial position or that they will not be viewed negatively by customers, financial markets, investors, or the media. In addition, the success of any acquisitions or investments also will depend, in part, on our ability to integrate the acquisition or investment with our existing operations.


24



The integration of businesses that we may acquire is likely to be a complex, time-consuming, and expensive process and we may not realize the anticipated revenues or other benefits associated with our acquisitions if we fail to successfully manage and operate the acquired business. If we fail in any acquisition integration efforts and are unable to efficiently operate as a combined organization utilizing common information and communication systems, operating procedures, financial controls, and human resources practices, our business, financial condition, and results of operations may be adversely affected.

In connection with certain acquisitions, we may agree to issue common stock or assume equity awards that dilute the ownership of our current stockholders, use a substantial portion of our cash resources, assume liabilities, record goodwill and amortizable intangible assets that will be subject to impairment testing on a regular basis and potential periodic impairment charges, incur amortization expenses related to certain intangible assets, and incur large and immediate write-offs and restructuring and other related expenses, all of which could harm our financial condition and results of operations.

Our actual operating results may differ significantly from our guidance.

We release guidance in our quarterly earnings conference calls, quarterly earnings releases, or otherwise, regarding our future performance that represents our management’s estimates as of the date of release. This guidance, which includes forward-looking statements, will be based on projections prepared by our management. These projections will not be prepared with a view toward compliance with published guidelines of the American Institute of Certified Public Accountants, and neither our registered public accountants nor any other independent expert or outside party compiles or examines the projections. Accordingly, no such person will express any opinion or any other form of assurance with respect to the projections.

Projections are based upon a number of assumptions and estimates that, while presented with numerical specificity, are inherently subject to significant business, economic and competitive uncertainties and contingencies, many of which are beyond our control and are based upon specific assumptions with respect to future business decisions, some of which will change. We will continue to state possible outcomes as high and low ranges which are intended to provide a sensitivity analysis as variables are changed but are not intended to imply that actual results could not fall outside of the suggested ranges. The principal reason that we release guidance is to provide a basis for our management to discuss our business outlook with analysts and investors. We do not accept any responsibility for any projections or reports published by any such third parties.

Guidance is necessarily speculative in nature, and it can be expected that some or all of the assumptions underlying the guidance furnished by us will not materialize or will vary significantly from actual results. Accordingly, our guidance is only an estimate of what management believes is realizable as of the date of release. Actual results may vary from our guidance and the variations may be material. In light of the foregoing, investors are urged not to rely upon our guidance in making an investment decision regarding our common stock.

Any failure to successfully implement our operating strategy or the occurrence of any of the events or circumstances set forth in this “Risk Factors” section in this Annual Report on Form 10-K could result in the actual operating results being different from our guidance and the differences may be adverse and material.

Insiders and principal stockholders will likely have significant influence over matters requiring stockholder approval.

Our directors, executive officers, and other principal stockholders beneficially own, in the aggregate, a substantial amount of our outstanding common stock. These stockholders could likely have significant influence over all matters requiring stockholder approval, including the election of directors and approval of significant corporate transactions such as a merger or other sale of our company or its assets.

The market price of our common stock may continue to be volatile.

The market price of our common stock has been, and is likely to continue to be, volatile and subject to fluctuations. Changes in the stock market generally, as it concerns our industry, as well as geopolitical, economic, and business factors unrelated to us, may also affect our stock price. Significant declines in the market price of our common stock or failure of the market price to increase could harm our ability to recruit and retain key employees, reduce our access to debt or equity capital, and otherwise harm our business or financial condition. In addition, we may not be able to use our common stock effectively as consideration in connection with any future acquisitions.


25



Anti-takeover provisions in our charter documents and under Delaware law could discourage, delay, or prevent a change in control of our company and may affect the trading price of our common stock.

Provisions in our amended and restated certificate of incorporation and bylaws may have the effect of delaying or preventing a change of control or changes in our management. Our amended and restated certificate of incorporation and amended and restated bylaws include provisions that:

authorize our Board of Directors to issue, without further action by the stockholders, up to 10,000,000 shares of undesignated preferred stock;
require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent;
specify that special meetings of our stockholders can be called only by our Board of Directors, the chairman of the board, the chief executive officer, or the president;
establish an advance notice procedure for stockholder approvals to be brought before an annual meeting of our stockholders, including proposed nominations of persons for election to our Board of Directors;
establish that our Board of Directors is divided into three classes, Class I, Class II, and Class III, with each class serving staggered terms;
provide that our directors may be removed only for cause;
provide that vacancies on our Board of Directors may be filled only by a majority vote of directors then in office, even though less than a quorum;
specify that no stockholder is permitted to cumulate votes at any election of directors; and
require a super-majority of votes to amend certain of the above-mentioned provisions.

In addition, we are subject to the provisions of Section 203 of the Delaware General Corporation Law regulating corporate takeovers. Section 203 generally prohibits us from engaging in a business combination with an interested stockholder subject to certain exceptions.

Changes in United States Generally Accepted Accounting Principles (“GAAP”) could adversely affect our financial results and may require significant changes to our internal accounting systems and processes.

We prepare our consolidated financial statements in conformity with GAAP. These principles are subject to interpretation by the Financial Accounting Standards Board (“FASB”), the SEC and various bodies formed to interpret and create appropriate accounting principles and guidance. The FASB periodically issues new accounting standards on a variety of topics. For information regarding new accounting standards, please refer to Note 2 of Notes to Consolidated Financial Statements under the heading “Note 2 - Recent Accounting Pronouncements.” These and other such standards generally result in different accounting principles, which may significantly impact our reported results or could result in variability of our financial results.

In preparing our financial statements we make certain assumptions, judgments and estimates that affect amounts reported in our consolidated financial statements, which, if not accurate, may significantly impact our financial results.

We make assumptions, judgments and estimates for a number of items, including the fair value of financial instruments, goodwill, long-lived assets and other intangible assets, the realizability of deferred tax assets, the recognition of revenue and the fair value of stock awards. We also make assumptions, judgments and estimates in determining the accruals for employee-related liabilities, including commissions and variable compensation, and in determining the accruals for uncertain tax positions, valuation allowances on deferred tax assets, allowances for doubtful accounts, and legal contingencies. These assumptions, judgments and estimates are drawn from historical experience and various other factors that we believe are reasonable under the circumstances as of the date of the consolidated financial statements. Actual results could differ materially from our estimates, and such differences could significantly impact our financial results.

Our business could be negatively affected as a result of actions of activist shareholders, and such activism could impact the trading value of our securities.


26



In recent years, shareholder activists have become involved in numerous public companies. Shareholder activists frequently propose to involve themselves in the governance, strategic direction and operations of the Company. Such proposals may disrupt our business and divert the attention of our Board of Directors and our management and employees, and any perceived uncertainties as to our future direction resulting from such a situation could result in the loss of potential business opportunities, interfere with our ability to execute our strategic plan be exploited by our competitors, cause concern to our current or potential customers, and make it more difficult to attract and retain qualified personnel and business partners, all of which could adversely affect our business. A proxy contest for the election of directors at our annual meeting could also require us to incur significant legal fees and proxy solicitation expenses. In addition, actions of activist shareholders may cause significant fluctuations in our stock price based on temporary or speculative market perceptions or other factors that do not necessarily reflect the underlying fundamentals and prospects of our business.

PART II

Item 5 — Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities

Market Information

Our common stock is quoted on the NASDAQ Stock Market under the symbol “ERII.”

Stockholders

As of December 31, 2018, there were approximately 38 stockholders of record of our common stock as reported by our transfer agent, one of which is Cede & Co., a nominee for Depository Trust Company (“DTC”). All of the shares of common stock held by brokerage firms, banks, and other financial institutions as nominees for beneficial owners are deposited into participant accounts at DTC and are therefore considered to be held of record by Cede & Co. as one stockholder.

Dividend Policy

We have never declared or paid any dividends on our common stock, and we do not currently intend to pay any dividends on our common stock for the foreseeable future. Any future determination to pay dividends on our common stock will be, subject to applicable law, at the discretion of our Board of Directors, and will depend upon, among other factors, our results of operations, financial condition, capital requirements, and contractual restrictions in loan or other agreements.

Stock Repurchase Program

On March 7, 2018, our Board of Directors authorized a stock repurchase program under which the Company, at the discretion of management, may repurchase up to $10.0 million in aggregate cost of our outstanding common stock (“March 2018 Authorization”). Under the repurchase program, purchases of shares of common stock may be made from time to time in the open market, or in privately negotiated transactions, in compliance with applicable state and federal securities laws. The timing and amounts of any purchases will be based on market conditions and other factors including price, regulatory requirements, and capital availability. The share buyback program does not obligate us to acquire any specific number of shares in any period, and may be expanded, extended, modified or discontinued at any time without prior notice. Under the March 2018 Authorization, as of December 31, 2018, the Company repurchased 1,193,102 shares at an aggregate cost of $10.0 million. The March 2018 Authorization expired in September 2018 and there was no repurchase authorization in place at December 31, 2018. The Company accounts for stock repurchases using the cost method. The aggregate cost includes fees charged in connection with acquiring the outstanding common stock.

In March 2017, our Board of Directors authorized a stock repurchase program under which the Company, at the discretion of management, could repurchase up to $15.0 million in aggregate cost of our outstanding common stock through September 30, 2017 (the “March 2017 Authorization”). At December 31, 2017, 541,177 shares, at an aggregate cost of $4.3 million, had been repurchased under the March 2017 Authorization.

Stock Performance Graph

The following graph shows the cumulative total stockholder return of an investment of $100 on December 31, 2013 in (i) our common stock, (ii) the NASDAQ Composite Index, and (iii) common stock of a selected group of peer issuers (“Peer Group”). Cumulative total return assumes the reinvestment of dividends, although dividends have never been declared on our stock, and is based on the returns of the component companies, weighted according to their capitalizations as of the end of each quarterly period. The NASDAQ Composite Index tracks the aggregate price performance of equity securities traded on the NASDAQ. The Peer Group tracks the weighted average price performance of equity securities of seven companies in our industry: Consolidated Water Co. Ltd.; Flowserve Corp.; Hyflux Ltd., Kurita Water Industries Ltd.; Pentair PLC; Tetra Tech, Inc.; and The Gorman-Rupp Company. The return of each component issuer of the Peer Group is weighted according to the respective issuer’s stock market capitalization at the end of each period for which a return is indicated. Our stock price performance shown in the graph below is not indicative of future stock price performance.

The following graph and its related information is not “soliciting material,” is not deemed “filed” with the Securities and Exchange Commission, and is not to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended or the Securities Exchange Act of 1934, as amended, whether made before or after the date hereof and irrespective of any general incorporation language contained in such filing.

Item 7 — Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management Discussion and Analysis of Financial Condition and Results of Operations is intended to help the reader understand our results of operations and financial condition. It should be read in conjunction with the Consolidated Financial Statements and related Notes included in Part II, Item 8, “Financial Statements and Supplementary Data,” in this Annual Report on Form 10-K.

Overview

Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “we”, “our” and “us”) (NASDAQ: ERII) is an engineering-driven technology company that engineers, designs, manufactures and supplies solutions for industrial fluid flow processes. The Company offers technologies which can drive meaningful, immediate cost savings and operational efficiencies for our customers. Currently, we operate in two markets - water and oil & gas, and our products are utilized in these markets to either recycle and convert wasted pressure energy into a usable asset or preserve pumps that are subject to hostile processing environments.

Energy Recovery was incorporated in Virginia in 1992 and reincorporated in Delaware in 2001. Our headquarters and principal research, development, and manufacturing facility is located in California. We are also constructing a new facility in Texas, which we hope to complete in 2019. We maintain direct sales offices and technical support centers in Europe, the Middle East and Asia.

Results of Operations

2018 Compared to 2017

Total Revenue

On January 1, 2018, we adopted ASC 606. Adoption of ASC 606 did not have a material impact on the timing of revenue and expense recognition for product revenue for either the Water segment or the cost-to-total cost (“CTC”) revenue contract in the Oil & Gas segment.

The implementation of ASC 606 for license and development revenue resulted in a material difference in the timing of revenue recognition under the new standard, with an overall acceleration of the recognition of deferred revenue under the VorTeq license agreement (the “VorTeq License Agreement”) that the Company entered into with Vorteq licensee. The amounts below have been adjusted for adoption of ASC 606. See Note 2, “Recent Accounting Pronouncements,” and Note 3, “Revenues,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplemental Data” of this Annual Report on Form 10-K, for further discussion on the adoption of ASC 606 and a reconciliation between prior year “As Previously Reported” and “As Adjusted” amounts. Since the full retrospective method was adopted, the Company has fully comparable period to period results.

Water segment product revenue increased in 2018, compared to 2017, due primarily to higher mega-project (“MPD”) sales of $6.1 million, and higher after-market shipments of $1.4 million, partially offset by lower original equipment manufacturer (“OEM”) sales of $1.3 million.

Oil & Gas segment product revenue, decreased in 2018, compared to 2017, due primarily to lower CTC revenue recognition associated with multiple IsoBoost systems.

A limited number of our customers account for a substantial portion of our product revenue. Revenue from customers representing 10% or more of product revenue varies from period to period. For the year ended December 31, 2018, two customers represented 15% and 11% of the Company’s product revenue. For the year ended December 31, 2017 no customer represented 10% or more of the Company’s product revenue, and for the year ended December 31, 2016, one customer, represented 11% of the Company’s product revenues. See Note 14, Geographical Information and Concentrations,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for further details on customer concentration.

In October 2015, through our subsidiary ERI Energy Recovery Ireland Ltd., we entered into the VorTeq License Agreement. License and development revenue increased $2.4 million, or 21%, in the twelve months ended December 31, 2018, compared to the twelve months ended December 31, 2017, due primarily to higher costs incurred under the cost driver input measure based on revenue recognition methodology of ASC 606.

See Note 2, “Recent Accounting Pronouncements,” of the Notes to Consolidated Financial Statements in Part  II, Item 8, “Financial Statements and Supplemental Data,” of this Annual Report on Form 10-K for further discussion on our license and development revenue recognition policy under ASC 606; and Note 15, “VorTeq Partnership and License Agreement,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplemental Data,” of this Annual Report on Form 10-K for additional discussion on the VorTeq License agreement.

Product gross profit represents our product revenue less our product cost of revenue. Our product cost of revenue consists primarily of raw materials, personnel costs (including stock-based compensation), manufacturing overhead, warranty costs, depreciation expense, and manufactured components.

Product gross margin increased in 2018 compared to 2017, due primarily to increased Water segment channel and product mix, manufacturing efficiencies and higher production levels, partially offset by decline in contribution of Oil & Gas segment to the total product gross margin due to higher project costs.

General and Administrative

General and administrative expense increased in 2018, compared to 2017, due primarily to higher employee-related compensation and benefits of $2.7 million, facility costs of $0.3 million and other costs of $0.3 million, partially offset by lower professional and legal costs of $0.8 million. Employee-related compensation and benefits included an increase in compensation of $1.7 million and stock-based compensation of $1.1 million, primarily due to a $0.9 million equity award modification charge chiefly related to the modification of certain equity awards held by the Company’s former President and Chief Executive Officer, who resigned on February 24, 2018, in consideration for his entering into a Settlement Agreement and Release.

Sales and Marketing

Sales and marketing expense decreased in 2018, compared to 2017, due primarily to lower employee-related compensation and benefits of $1.8 million.

Research and Development

Research and development expense increased in 2018, compared to 2017, due primarily to increased occupancy and depreciation cost of $1.3 million, higher employee-related compensation and benefits of $1.1 million, direct research and development project costs of $0.8 million and other costs of $0.4 million. Employee-related compensation and benefits included an increase in compensation of $0.7 million and stock-based compensation of $0.3 million.

Amortization of Intangible Assets

Amortization of intangible assets is related to finite-lived intangible assets acquired as a result of our purchase of Pump Engineering, LLC in December 2009. There was no material change in our amortization amounts in 2018, compared to 2017.

Total other income (expense), net increased in 2018, compared to 2017, due primarily to interest income on higher investment balances and improvement in foreign currency exchange rates.

Income Taxes

Our income tax benefit was $10.7 million for the year ended December 31, 2018 compared to a tax benefit of $8.4 million for the year ended December 31, 2017. On December 22, 2017, President Trump signed into law, the U.S. Tax Cut and Jobs Act (“Tax Act”), which significantly changed existing U.S. tax laws which impacted in 2017, including, but not limited to, (1) requiring companies to pay a one-time deemed repatriation tax on certain un-repatriated earnings of foreign subsidiaries; (2) re-measurement of deferred tax assets and liabilities at the new 21% tax rate; and (3) bonus depreciation that will allow for full expensing of qualified property.

The tax benefit of $10.7 million for the year ended December 31, 2018, included a $12.3 million U.S. federal and state deferred tax benefit related to the income tax effects of a tax election related to a change to the Company’s international tax structure in Ireland that was effective for the quarter ended June 30, 2018. This election resulted in a deferred tax asset related to tax expense recorded on earnings and profits under the Tax Act on deferred revenue not yet recognized under US GAAP. In addition, the 2018 tax results reflect $800,000 of tax benefit from stock-based compensation tax deductions in excess of the related book expense. The Company continues to evaluate the impact of the tax law changes to its overall structure and income tax planning. The Company continues to assert that the accumulated foreign earnings in Spain and Canada are permanently reinvested.

The tax benefit of $8.4 million for the year ended December 31, 2017, consisted of a net $10.1 million U.S. federal and state deferred tax benefit after taking into consideration a valuation allowance release on all but $1.4 million of our U.S. federal and state deferred tax assets, less a valuation allowance for the Irish deferred tax assets of $1.3 million less U.S. federal, state and foreign current tax expense of $0.4 million. In addition, as a result of enactment of the legislation, during the fourth quarter of 2017, the Company incurred a one-time income tax expense of $7.0 million related to the deemed repatriation tax on accumulated foreign earnings (of which $0.3 million is a cash charge and the remaining $6.7 million represents a non-cash discrete tax expense largely from the utilization of net operating loss carryovers). The Company also incurred a non-cash income tax expense of $2.5 million related to the re-measurement of certain deferred tax assets and liabilities based on the tax rates from the Tax Act.

In October 2015, through our subsidiary ERI Energy Recovery Ireland Ltd., we entered into the VorTeq Licensee (“VorTeq License Agreement”), an international customer. The VorTeq License Agreement has a term of 15-years for the exclusive, worldwide right to use our VorTeq technology for hydraulic fracturing onshore operations. License revenue was higher in 2017 as compared to 2016 due to higher costs incurred in 2017 under the input measure cost driver revenue recognition methodology of ASC 606. See Note 3, “Revenues,” and Note 15,“Vorteq Partnership and Licensing Agreement,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for further details.

The tax benefit of $8.4 million for the year ended December 31, 2017, consisted of a net $10.1 million U.S. federal and state deferred tax benefit after taking into consideration a valuation allowance release on all but $1.4 million of our U.S. federal and state deferred tax assets, less a valuation allowance for the Irish deferred tax assets of $1.3 million less U.S. federal, state and foreign current tax expense of $0.4 million. With respect to the 2017 year, as a result of enactment of the legislation, during the fourth quarter of 2017, the Company incurred a one-time income tax expense of $7.0 million related to the deemed repatriation tax on accumulated foreign earnings (of which $0.3 million is a cash charge and the remaining $6.7 million represents a non-cash discrete tax expense largely from the utilization of net operating loss carryovers). The Company also incurred a non-cash income tax expense of $2.5 million related to the re-measurement of certain deferred tax assets and liabilities based on the recently enacted rates from the Tax Act.

There was immaterial tax benefit for the year ended December 31, 2016 which consisted of $0.3 million benefit related to losses in our Ireland subsidiary, which was partially offset by tax expense of $0.3 million related to the deferred tax effects associated with the amortization of goodwill and other taxes.

Liquidity and Capital Resources

Overview

Historically, our primary source of cash to fund our operations and capital expenditures has been proceeds from customer payments for our products and services and the issuance of common stock. As of December 31, 2018, we have issued common stock for aggregate net proceeds of $104.6 million, excluding common stock issued in exchange for promissory notes.

As of December 31, 2018, our principal sources of liquidity consisted of unrestricted cash and cash equivalents of $22.0 million; short-term investments of $73.3 million that are primarily invested in marketable debt securities; and accounts receivable, net of allowances of $10.2 million. As of December 31, 2018, our unrestricted cash, cash equivalents and short-term investments held outside the U.S. was $20.3 million. We invest cash not needed for current operations predominantly in high-quality, investment-grade, marketable debt instruments with the intent to make such funds available for operating purposes as needed.

At December 31, 2018 and 2017, we had $4.1 million and $6.3 million, respectively, of contract assets. In the Water segment, contract assets may be related to either contract terms which specify payment when the product arrives at a destination or to customer contractual holdback provisions. Under the holdback provisions we invoice the final retention payment(s) due under certain sales contracts in the next 12 months. The customer holdbacks represent amounts intended to provide a form of security for the customer. In the Oil & Gas segment, we had unbilled project costs, of $1.3 million at December 31, 2018. See Note 3, “Revenues,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for additional information about contract assets.

Loan and Pledge Agreement

On January 27, 2017, we entered into a loan and pledge agreement (the “Loan and Pledge Agreement”) with a financial institution. The Loan and Pledge Agreement provides for a committed revolving credit line of $16.0 million and an uncommitted revolving credit line of $4.0 million. Under the Loan and Pledge Agreement, we are allowed to borrow and request letters of credit against the eligible assets held from time to time in the pledged account maintained with the financial institution. Revolving loans incur interest per annum at a base rate equal to the London Interbank Offered Rate (also referred to as “LIBOR”) plus 1.5%. Any default bears the aforementioned interest rate plus an additional 2%. The unused portion of the credit line is subject to a fee. We are subject to certain financial and administrative covenants under the Loan and Pledge Agreement. The Loan and Pledge Agreement was amended on March 30, 2018 to extend the termination date of the Loan and Pledge Agreement from March 31, 2018 to March 31, 2020, of which the Company paid closing fees of $16 thousand. The Loan and Pledge Agreement was amended on March 17, 2017, to increase the permitted indebtedness under the agreement and to modify certain revolving loan credit options. No other provisions of the Loan and Pledge Agreement were amended. The Loan and Pledge Agreement was further amended on August 24, 2018 to permit the Company to incur indebtedness owed to a foreign subsidiary in an aggregate amount not to exceed $66.0 million, which amount is subordinated to any amounts outstanding under the Loan and Pledge Agreement. As of December 31, 2018, no debt was outstanding under the Loan and Pledge Agreement, however, the standby letters of credit outstanding with this Financial Institution is deducted from the total revolving credit line. As of December 31, 2018, we were in compliance with loan covenants.

Stand-by Letters of Credit

At December 31, 2018, we have stand-by letters of credit with various financial institutions totaling $8.8 million whereby we are required to maintain a restricted cash balance of $0.1 million and a U.S. investment balance of $8.7 million. Stand-by letters of credit are subject to fees based on the amount of the letter of credit, that are payable quarterly and are non-refundable. See Note 8, “Long-term Debt and Lines of Credit,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for additional information about our stand-by letters of credit arrangements.

Share Repurchases

On March 7, 2018, our Board of Directors authorized a stock repurchase program under which the Company, at the discretion of management, may repurchase up to $10.0 million in aggregate cost of our outstanding common stock (“March 2018 Authorization”). Under the repurchase program, purchases of shares of common stock may be made from time to time in the open market, or in privately negotiated transactions, in compliance with applicable state and federal securities laws. The timing and amounts of any purchases will be based on market conditions and other factors including price, regulatory requirements, and capital availability. The share buyback program does not obligate us to acquire any specific number of shares in any period, and may be expanded, extended, modified or discontinued at any time without prior notice. Under the March 2018 Authorization, as of December 31, 2018, the Company repurchased 1,193,102 shares at an aggregate cost of $10.0 million. The March 2018 Authorization expired in September 2018 and there was no repurchase authorization in place at December 31, 2018.

In March 2017, our Board of Directors authorized a stock repurchase program under which the Company, at the discretion of management, could repurchase up to $15.0 million in aggregate cost of our outstanding common stock through September 30, 2017 (the “March 2017 Authorization”). At December 31, 2017, 541,177 shares, at an aggregate cost of $4.3 million, had been repurchased under the March 2017 Authorization.

See Note 11, “Stockholder’s Equity,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for additional information about our share repurchase programs.

Cash Flows from Operating Activities

Cash provided by operating activities is generated by net income (loss) adjusted for certain non-cash items and changes in assets and liabilities.

Cash provided by operating activities was higher in 2018, compared to 2017, by $4.7 million, primarily due to higher net income of $3.7 million and increased stock-based compensation of $1.2 million, partially offset by decrease in deferred income taxes of $1.5 million.

Net changes of cash used for assets and liabilities of $14.7 million in 2018 were primarily attributable to
a $13.6 million decrease in contract liabilities due to the recognition of revenue related to our exclusive license agreement,
a $2.3 million decrease in accounts payable and a $1.9 million increase in inventories due to increased production, offset by a $4.1 million decrease in accounts receivable and contract assets due to timing of invoices and payments.

Cash provided by operating activities was lower in 2017, compared to 2016, by $2.1 million, due primarily to higher non-cash for deferred income tax adjustment of $8.4 million and cash used for operating assets and liabilities of $15.1 million, partially offset by higher net income of $14.6 million.

Net changes of cash used for assets and liabilities of $15.1 million in 2017 were primarily attributable to a $11.9 million decrease in contract liabilities due to the recognition of revenue related to our exclusive license agreement,a $5.0 million decrease in accounts receivable and contract assets due to timing of invoices and payments,

42



a $1.3 million increase in inventories due to increased production, partially offset by a $2.7 million increase in accounts payable and accrued expenses and other liabilities, and a $0.4 million increase in taxes payable.

Net changes of cash used for assets and liabilities of $5.0 million in 2016 were primarily attributable to
a $6.3 million decrease in contract liabilities due to the recognition of revenue related to our exclusive license agreement,
a $0.4 million decrease in accounts payable, partially offset by a $2.3 million decrease in inventories due to decreased shipments, a $0.4 million increase in accounts receivable and contract assets due to timing of invoices and payments.

Cash Flows from Investing Activities

Cash flows from investing activities primarily relate to maturities and purchases of marketable securities to preserve principal and liquidity while at the same time maximizing yields without significantly increasing risk, and capital expenditures to support our growth, and changes in our restricted cash used to collateralize our stand-by letters of credit and other contingent considerations.

Cash used in 2018 was primarily attributable to $86.2 million used to purchase investments and $5.2 million for capital expenditures. These were offset by $81.3 million in maturities of marketable security investments.

Also, in 2018 and 2017 due to the adoption of ASC 842, the Company recorded a non-cash impact of $10.4 million and $3.3 million lease liability respectively, with a corresponding adjustment to the right-of-use asset.

Cash used in 2017 was primarily attributable to $80.6 million used to purchase investments, and $7.4 million for capital expenditures. These were offset by $49.1 million in maturities of marketable security investments.

Cash used in 2016 was primarily attributable to $46.6 million used to purchase investments, and $1.1 million for capital expenditures. These were offset by $7.5 million in maturities of marketable security investments.

Cash Flows from Financing Activities

Net cash used in 2018 was primarily due to the use of $10.0 million to repurchase our common stock, partially offset by $4.3 million received from the issuance of common stock related to stock option exercises.

Net cash provided in 2017 was primarily due to $5.5 million received from the issuance of common stock related to option exercises partially offset by $4.2 million to repurchase our common stock.

Net cash used in 2016 was primarily due to 9.4 million to repurchase our common stock, partially offset by $6.6 million received from the issuance of common stock related to stock option exercises.


Liquidity and Capital Resource Requirements

We believe that our existing resources and cash generated from our operations will be sufficient to meet our anticipated capital requirements for at least the next 12 months. However, we may need to raise additional capital or incur additional indebtedness to continue to fund our operations or to support acquisitions in the future and/or fund investments in our latest technology arising from rapid market adoption that could require us to seek additional equity or debt financing. Our future capital requirements will depend on many factors, including the continuing market acceptance of our products, our rate of revenue growth, the timing of new product introductions, the expansion of our research and development, manufacturing, and sales and marketing activities, the timing and extent of our expansion into new geographic territories, and the amount and timing of cash used for stock repurchases. In addition, we may enter into potential material investments in, or acquisitions of, complementary businesses, services, or technologies in the future, which could also require us to seek additional equity or debt financing. Should we need additional liquidity or capital funds, these funds may not be available to us on favorable terms, or at all.

43



Contractual Obligations

We lease facilities and equipment under fixed non-cancellable operating leases that expire on various dates through 2028. Additionally, in the course of our normal operations, we have entered into cancellable purchase commitments with our suppliers for various key raw materials and component parts. The purchase commitments covered by these arrangements are subject to change based on our sales forecasts for future deliveries.

This table excludes agreements with guarantees or indemnity provisions that we have entered into with customers and others in the ordinary course of business. Based on our historical experience and information known to us as of December 31, 2018, we believe that our exposure related to these guarantees and indemnities as of December 31, 2018 was not material.

Off-Balance Sheet Arrangements

During the periods presented, we did not have any relationships with unconsolidated entities or financial partnerships such as entities often referred to as structured finance or special purpose entities, which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical Accounting Policies and Estimates

Our Consolidated Financial Statements are prepared in accordance with generally accepted accounting principles (“GAAP”) in the United States. These accounting principles require us to make estimates and judgments that can affect the reported amounts of assets and liabilities as of the date of the Consolidated Financial Statements as well as the reported amounts of revenue and expense during the periods presented. We believe that the estimates and judgments upon which we rely are reasonable based upon information available to us at the time that we make these estimates and judgments. To the extent that there are material differences between these estimates and actual results, our consolidated financial results will be affected. The accounting policies that reflect our more significant estimates and judgments and which we believe are the most critical to aid in fully understanding and evaluating our reported financial results are revenue recognition, capitalization of research and development assets; valuation of stock options; valuation and impairment of goodwill and acquired intangible assets; valuation adjustments for excess and obsolete inventory; deferred taxes and valuation allowances on deferred tax assets; and evaluation and measurement of contingencies.

The following is not intended to be a comprehensive list of all of our accounting policies or estimates. Our accounting policies are more fully described in Note 1, Description of Business and Significant Accounting Policies of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K.

Revenue Recognition

Revenues are recognized when control of the promised goods or services is transferred to the Company’s customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. At the inception of each contract, performance obligations are identified and the total transaction price is allocated to the performance obligations.

The Company’s contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative stand-alone selling price. The Company generally determines standalone selling prices based on the prices charged to customers.

With respect to termination, the Company does not have the ability to cancel a contract for convenience. In general, customers can cancel for convenience upon the payment of a termination fee that covers costs and profit. It is rare for customers to cancel contracts.

See Note 3, “Revenues” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for more detail on product and service revenue recognition - Water segment, cost-to-total cost (“CTC”) revenue recognition- Oil and Gas segment, license and development revenue recognition - Oil and Gas segment.

Capitalization of Research and Development Assets
The costs of materials that are acquired for research and development activities and have no alternative future uses (in research and development projects or otherwise) are expensed as incurred.  With respect to tangible assets acquired or constructed for R&D activities, if the costs of materials that are acquired or constructed for a particular research and development project have alternative future uses (in other research and development projects or otherwise), they are capitalized as an asset and the cost of depreciation is charged to expense. 


45



Stock-Based Compensation

We measure and recognize stock-based compensation expense based on the fair value measurement for all stock-based awards made to our employees and directors — including restricted stock units (“RSUs”), and employee stock options — over the requisite service period (typically the vesting period of the awards). The fair value of RSUs is based on our stock price on the date of grant. The fair value of stock options is calculated on the date of grant using the Black-Scholes option pricing model, which requires a number of complex assumptions including expected life, expected volatility, risk-free interest rate, and dividend yield. The estimation of awards that will ultimately vest requires judgment, and to the extent that actual results or updated estimates differ from our current estimates, such amounts are recorded as a cumulative adjustment in the period in which the estimates are revised. See Note 12, “Stock-Based Compensation,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for further discussion of stock-based compensation.

Goodwill and Other Intangible Assets

The purchase price of an acquired company is allocated between intangible assets and the net tangible assets of the acquired business with the residual purchase price recorded as goodwill. The determination of the value of the intangible assets acquired involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows that an asset is expected to generate in the future and the appropriate weighted average cost of capital.

Acquired intangible assets with determinable useful lives are amortized on a straight-line or accelerated basis over the estimated periods benefited, ranging from one to 20 years. Acquired intangible assets with contractual terms are amortized over their respective legal or contractual lives. Customer relationships and other non-contractual intangible assets with determinable lives are amortized over periods ranging from five to 20 years.

We evaluate the recoverability of intangible assets by comparing the carrying amount of an asset to estimated future net undiscounted cash flows generated by the asset. If such assets are considered to be impaired, the impairment recognized is measured as the amount by which the carrying amount of the assets exceeds the fair value of the assets. The evaluation of recoverability involves estimates of future operating cash flows based upon certain forecasted assumptions, including, but not limited to, revenue growth rates, gross profit margins, and operating expenses over the expected remaining useful life of the related asset. A shortfall in these estimated operating cash flows could result in an impairment charge in the future.

Goodwill is not amortized, but is evaluated annually for impairment at the reporting unit level or when indicators of a potential impairment are present. We estimate the fair value of the reporting unit using the discounted cash flow and market approaches. Forecast of future cash flows are based on our best estimate of future net sales and operating expenses, based primarily on expected category expansion, pricing, market segment, and general economic conditions.

As of December 31, 2018 and December 31, 2017, acquired intangibles, including goodwill, relate to the acquisition of Pump Engineering, LLC during the fourth quarter of 2009. See Note 7, “Goodwill and Intangible Assets,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for further discussion of intangible assets.

Inventories

Inventories are stated at the lower of cost (using the first-in, first-out “FIFO” method) or market. We calculate inventory valuation adjustments for excess and obsolete inventory based on current inventory levels, movement, expected useful lives, and estimated future demand of the products and spare parts.


46



Income Taxes

Current and non-current tax assets and liabilities are based upon an estimate of taxes refundable or payable for each of the jurisdictions in which the Company is subject to tax. In the ordinary course of business, there is inherent uncertainty in quantifying income tax positions. We assess income tax positions and record tax benefits for all years subject to examination based upon the Company’s evaluation of the facts, circumstances, and information available at the reporting dates. For those tax positions where it is more likely than not that a tax benefit will be sustained, we record the largest amount of tax benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more likely than not that a tax benefit will be sustained, no tax benefit is recognized in the financial statements. When applicable, associated interest and penalties are recognized as a component of income tax expense. Accrued interest and penalties are included within the related tax asset or liability on the Consolidated Balance Sheets.

Deferred income taxes are provided for temporary differences arising from differences in bases of assets and liabilities for tax and financial reporting purposes. Deferred income taxes are recorded on temporary differences using enacted tax rates in effect for the year in which the temporary 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. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Significant judgment is required in determining whether and to what extent any valuation allowance is needed on the Company’s deferred tax assets. In making such a determination, we consider all available positive and negative evidence including recent results of operations, scheduled reversals of deferred tax liabilities, projected future income, and available tax planning strategies. See Note 10, Income Taxes,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for further discussion of the tax valuation allowance.

On December 22, 2017, President Trump signed into law the Tax Act, which significantly changed existing U.S. tax laws. Following the enactment of the Tax Act, the SEC staff issued SAB 118, which provided guidance on accounting for the tax effects of the Tax Act. SAB 118 provided a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the accounting under ASC 740. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for certain income tax effects of the Tax Act is incomplete but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax law that were in effect immediately before the enactment of the Tax Act. Our adjustments were final in 2017. See Note 10, Income Taxes,of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K for a discussion of our income tax accounting related to the Tax Act.

Our operations are subject to income and transaction taxes in the U.S. and in foreign jurisdictions. Significant estimates and judgments are required in determining our worldwide provision for income taxes. Some of these estimates are based on interpretations of existing tax laws or regulations. The ultimate amount of tax liability may be uncertain as a result.

Recent Accounting Pronouncements

See Note 2, “Recent Accounting Pronouncements,” of the Notes to Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K regarding the impact of certain recent accounting pronouncements on our Consolidated Financial Statements.

Item 7A — Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Risk

Our exposures are to fluctuations in exchange rates for USD versus the British Pound, Saudi Riyal, United Arab Emirates Dirham, Euro, Chinese Yuan, Indian Rupee and Canadian Dollar. Changes in currency exchange rates could adversely affect our consolidated operating results or financial position.

Our revenue contracts have been denominated in U.S. Dollars (“USD”). At times our international customers may have difficulty in obtaining USD to pay our receivables, thus increasing collection risk and potential doubtful account expense. As we expand our international sales, a portion of our revenue could be denominated in foreign currencies. As a result, our cash and cash equivalents and operating results could be increasingly affected by changes in exchange rates.

In addition, we pay many vendors in foreign currency and therefore, are subject to changes in foreign currency exchange rates.

Our international sales and service operations incur expense that is denominated in foreign currencies. This expense could be materially affected by currency fluctuations. Our international sales and services operations also maintain cash balances denominated in foreign currencies. To decrease the inherent risk associated with translation of foreign cash balances into our reporting currency, we do not maintain excess cash balances in foreign currencies.

We have not hedged our exposure to changes in foreign currency exchange rates because expenses in foreign currencies have been insignificant to date, and exchange rate fluctuations have had little impact on our operating results and cash flows.

Interest Rate Risk and Credit Risk

We have an investment portfolio of fixed-income marketable debt securities, including amounts classified as cash equivalents and short-term investments. The primary objective of our investment activities is to preserve principal and liquidity while at the same time maximizing yields without significantly increasing risk. We invest primarily in investment-grade short-term debt instruments of high-quality corporate issuers and the U.S. government and its agencies. These investments are subject to counterparty credit risk. To minimize this risk, we invest pursuant to a Board-approved investment policy. The policy mandates high credit rating requirements and restricts our exposure to any single corporate issuer by imposing concentration limits.

At December 31, 2018, our investments with maturity dates less than 12 months, totaled approximately $73.3 million and were classified as short-term investments. Those with maturity dates more than 12 months which totaled approximately $1.3 million are classified as long-term investments. These investments are subject to interest fluctuations and will decrease in market value if interest rates increase. To minimize the exposure due to adverse shifts in interest rates, we maintain investments with an average maturity of less than seven months. A hypothetical 1% increase in interest rates would have resulted in an approximately $0.3 million decrease in the fair value of our fixed-income debt securities as of December 31, 2018.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the stockholders and the Board of Directors of Energy Recovery, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Energy Recovery, Inc. and subsidiaries (the "Company") as of December 31, 2018, the related consolidated statements of operations, comprehensive income (loss), stockholders' equity, and cash flows, for the year then ended, and the related notes (collectively referred to as the "financial statements"). In our opinion, the 2018 financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018, and the results of its operations and its cash flows for the year then ended in conformity with accounting principles generally accepted in the United States of America.

The consolidated financial statements of the Company as of December 31, 2017 and for each of the two years in the period then ended (collectively referred to as the “2017 and 2016 financial statements”), before the effects of the adjustments to retrospectively apply the change in accounting discussed in Note 2 to the financial statements, were audited by other auditors whose report, dated March 8, 2018, expressed an unqualified opinion on those statements. We have also audited the adjustments to the 2017 and 2016 financial statements to retrospectively apply the change in accounting for the adoption of Revenue from Contracts with Customers (Topic 606), ASU No. 2016-02, Leases (Topic 842) and ASU 2016-18, Statement of Cash Flows (Topic 230) in 2018, as discussed in Note 2 to the financial statements. In our opinion, such retrospective adjustments are appropriate and have been properly applied. However, we were not engaged to audit, review, or apply any procedures to the 2017 and 2016 financial statements of the Company other than with respect to the retrospective adjustments, and accordingly, we do not express an opinion or any other form of assurance on the 2017 and 2016 financial statements taken as a whole.

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, 2018, 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 March 7, 2019, expressed an unqualified opinion on the Company's internal control over financial reporting.

Change in Accounting Principle

As discussed in Note 2 to the financial statements, effective January 1, 2018, the Company adopted Revenue From Contracts With Customers (Topic 606), using the full retrospective approach.

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 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 the financial statements are free of material misstatement, whether due to error or fraud. Our audit 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 audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
To the stockholders and the Board of Directors of Energy Recovery, Inc.
Opinion on Internal Control over Financial Reporting
We have audited the internal control over financial reporting of Energy Recovery, Inc. and subsidiaries (the “Company”) as of December 31, 2018, 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, 2018, 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 financial statements as of and for the year ended December 31, 2018, of the Company and our report dated March 7, 2019, expressed an unqualified opinion on those financial statements and included an explanatory paragraph regarding the Company’s adoption of a new accounting standard.
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 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.

Energy Recovery, Inc.
San Leandro, California

Opinion on the Consolidated Financial Statements
We have audited, before the effects of the adjustments to retrospectively apply the changes in accounting described in Note 2 for the adoption of Revenue from Contracts with Customers (Topic 606), ASU No. 2016-02, Leases (Topic 842) and ASU 2016-18, Statement of Cash Flows (Topic 230), the accompanying consolidated balance sheet of Energy Recovery, Inc. (the “Company”) and subsidiaries as of December 31, 2017, the related consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for each of the two years in the period ended December 31, 2017 and the related notes (collectively referred to as the “consolidated financial statements). Further, the 2017 and 2016 financial statements before the effects of the adjustments discussed in Note 2 are not presented herein. In our opinion, the 2017 and 2016 consolidated financial statements, before the effects of the adjustments to retrospectively apply the changes in accounting described in Note 2, present fairly, in all material respects, the financial position of the Company and subsidiaries at December 31, 2017, and the results of their operations and their cash flows for each of the two years in the period ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.
We were not engaged to audit, review, or apply any procedures to the adjustments to retrospectively apply the changes in accounting described in Note 2, and, accordingly, we do not express an opinion or any other form of assurance about whether such adjustments are appropriate and have been properly applied. Those adjustments were audited by Deloitte & Touche LLP.
Basis for Opinion
These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“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 consolidated 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 consolidated 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 consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.
