Dear Fellow Shareholders:

2018 was a successful and pivotal year that we believe has positioned 
Energy Recovery for sustainable growth in 2019 and beyond.  In 
2018, we achieved record revenues of $74.5 million and a product 
gross margin of 71 percent.  Our thriving Water business, which 
saw 11 percent growth driven by PX® Pressure Exchanger® demand, 
underpinned these remarkable results. 

Furthermore, we implemented several organizational changes and 
investments  to  drive  and  support  future  growth.    First  was  the 
creation of two distinct business units — a Water unit and an Oil 
& Gas unit — to provide greater accountability and clarity regarding 
goals,  responsibilities,  and  resources  required  for  each  business 
line.  Second, we expanded our Water manufacturing operations 
and capacity to meet current and anticipated demand.  Third, we 
made several significant investments in Oil & Gas to build out our 
in-house testing capabilities.  

We are excited about what 2019 holds.  Our strategic objectives — to 
expand and reinvest in our Water business and to advance the VorTeq 
system to commercialization — are ambitious yet achievable, and 
our momentum from 2018 has greatly improved our readiness to 
succeed.  We are proud of our ability to make these growth-oriented 
investments while maintaining a strong balance sheet.

Our Water business entered 2019 with the greatest backlog and 
strongest pipeline in our company’s history and is poised to exceed 
last year’s record results.  Just last month, we shipped our 20,000th 
PX Pressure Exchanger — an impressive milestone for a product 
that started in a garage only two decades ago.

The growth in Water shows no signs of slowing.  Global adoption of 
seawater reverse osmosis (SWRO) desalination is accelerating as 
the world seeks solutions to providing new supplies of fresh water 
to meet ever-increasing demand.  A cyclical slowdown does not 
appear to be materializing, representing a break from previous industry 
E
patterns.  Indeed, we see an enduring shift emerging where demand 
highs and lows are permanently elevated beyond previous trend lines.  
Supplementing this demand growth is an ongoing transition from 
thermal desalination to the more cost-effective SWRO desalination 
process, a shift driven in part by the energy cost savings delivered by 
our PX Pressure Exchanger and turbocharger devices.  These trends 
are an opportunity, and we are aggressively pursuing initiatives to 
provide further value to our water customers and the world.

Our Oil & Gas business has made real progress advancing VorTeq 
system  design  enhancements.    Our  investments  in  both  people 
and  equipment  have  allowed  us  to  transition  from  sporadic  and 
often limited testing to regular, full-scale field testing at our new 
Commercial Development Center outside Houston, Texas.  Rigorous 
and continuous testing in real-life conditions is critical for two reasons.  
First, we gain real-time insight that lets us more rapidly innovate 
and  shorten  the  iterations  between  design  concept  to  validated 
solution.  Second, it is imperative to proving our new technology has 
the durability and reliability needed to withstand the hardship of a 
frac site and to challenge the status quo of a mature and competitive 
industry.  As we accumulate consistent runtime, the challenges we 
face are diminishing in complexity, thereby shortening the path to 
commercialization.  With regards to our post-commercialization 
strategy,  the  Commercial  Development  Center  will  ultimately 
house our tungsten carbide machining capabilities for the VorTeq 
PX  cartridge  and  allow  for  iterative  system  testing  and  ongoing 
improvements.

The future looks bright for Energy Recovery.  We are confident in our 
ability to execute our growth strategy and generate real shareholder 
value this year, next year and for the foreseeable future.  The positive 
outlook for both our business lines reinforces this view, as does our 
track record of overcoming any challenges in pursuit of delivering 
high-impact  technologies  and  solutions  to  our  customers.    We 
have transformed the economics of SWRO desalination through 
our technological innovation and believe we are verging on a similar 
transformation in hydraulic fracturing as we drive the VorTeq system 
to commercialization.

Thank you for your continued support.

ITEM 1 — BUSINESS 

Overview 

PART I 

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. 

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.  

-3- 

 
 
 
 
 
 
 
 
 
 
 
 
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. 

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. 

-4- 

 
 
 
 
 
 
 
 
 
 
 
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. 

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 

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

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. 

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. 

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

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.

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.

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.

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. 

-14- 

 
 
 
 
 
 
 
 
 
 
 
 
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.

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. 

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 

-16- 

 
 
 
 
 
 
 
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. 

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. 

-17- 

 
 
 
 
 
 
 
 
 
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. 

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 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. 

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. 

-19- 

 
 
 
 
 
 
 
 
 
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. 

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 

-20- 

 
 
 
 
 
 
 
 
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. 

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. 

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.

Item 2 — Properties 

We lease approximately 171,000 square feet of space in San Leandro, California for product manufacturing, research 
and development, and executive headquarters under a lease that expires on January 1, 2029. We believe that this facility will 
be  adequate  for  our  purposes  for  the  foreseeable  future.  Additionally,  we  lease  offices  in  Dubai,  United  Arab  Emirates; 
Shanghai, Peoples Republic of China; Houston, Texas and on January 10, 2019, we entered into an industrial lease agreement 
in Katy, Texas.

PART II 

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

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.

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 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

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.

Water segment product revenue increased in 2017, compared to 2016, due primarily to higher mega-project (“MPD”) 
sales of $5.6 million and original equipment manufacturer (“OEM”) sales of $1.3 million, partially offset by lower after-
market sales of $0.1 million. 

Oil  &  Gas  segment  product  revenue,  increased  in  2017,  compared  to  2016,  due  primarily  to  the  cost-to-total  cost

of $0.3 million. 

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, 2017 no customer 
represented  10%  or  more  of the  Company’s  product revenue,  and for  the  year  ended December 31, 2016,  one  customer,

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,”

General and administrative expense increased in 2017, compared to 2016, due primarily to higher employee-related 
compensation and benefits of $0.5 million, facility costs of $0.4 million and other costs of $0.3 million, partially offset by 
lower  professional  and  legal  costs  of  $0.5 million.  Employee-related  compensation  and  benefits  included  an  increase  in 
compensation of $0.3 million and stock-based compensation of $0.2 million.

Sales and Marketing 

Sales  and  marketing  expense  increased  in  2017,  compared  to  2016,  due  primarily  to  higher  employee-related 
compensation  and  benefits  of  $0.4 million  and  higher  professional  services  of  $0.1 million,  partially  offset  by  lower 
marketing and other costs of $0.2 million. Employee-related compensation and benefits included an increase in commissions 
of  $0.3 million  and  stock-based  compensation  of  $0.3 million,  partially  offset  by  lower  compensation  and  incentive 
compensation of $0.2 million. 

Research and Development 

Research and development expense increased in 2017, compared to 2016, due primarily to higher employee-related 
compensation and benefits of $1.6 million, direct research and development project costs of $1.5 million and other costs of 
$0.2 million. Employee-related compensation and benefits included an increase in compensation of $1.4 million and stock-
based compensation of $0.3 million, partially offset by lower incentive compensation of $0.1 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 2017, compared to 2016.

foreign currency exchange. 

Income Taxes 

Our income tax benefit was $8.4 million for the year ended December 31, 2017 compared to a $6 thousand tax benefit 

for the year ended December 31, 2016. 

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.

Statements and Supplementary Data,” of this Annual Report on Form 10-K. 

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 
liabilities 

tax  adjustment  of $8.4 million and  cash used  for operating  assets  and 

income 

non-cash for  deferred 
of $15.1 million, partially offset by higher net income of $14.6 million.

invoices  and  payments, 
a $5.0 million decrease in  accounts  receivable  and  contract  assets  due

timing  of 

to 

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.

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. 

The following is a summary of our contractual obligations as of December 31, 2018.

Purchase obligations are related to open purchase orders for materials and supplies.

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.   

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. 

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. We believe that our audit provides a reasonable basis for our opinion.

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.

The Board of Directors and Stockholders 
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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Note 1 — Description of Business and Significant Accounting Policies 

Energy Recovery, Inc. and its wholly-owned subsidiaries (the “Company,” “Energy Recovery,” “our,” “us,” or “we”) 
is  an  energy  solutions  provider  to  industrial  fluid  flow  markets  worldwide.  The  Company’s  core  competencies  are  fluid 
dynamics and advanced material science. The Company’s products make industrial processes more operationally and capital 
expenditure efficient. The Company’s solutions convert wasted pressure energy into a reusable asset and preserve or eliminate 
pumping  technology  in  hostile  processing  environments.  The  Company’s  solutions  are  marketed  and  sold  in  fluid  flow 
markets,  such  as  water,  oil  &  gas,  and  chemical  processing,  under  the  trademarks  ERI®,  PX®,  Pressure  Exchanger®,  PX 
Pressure Exchanger®, VorTeq™, MTeq™, IsoBoost®, IsoGen®, AT™, and AquaBold™. The Company owns, manufactures, and/or 
develops its solutions, in whole or in part, in the United States of America, (“U.S.”) and the Republic of Ireland (“Ireland”). 

Basis of Presentation 

The  Company’s  Consolidated  Financial  Statements  include  the  accounts of Energy  Recovery, Inc.  and  its  wholly-

owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. 

Reclassifications and Retroactive Adjustments 

Certain prior year amounts have been reclassified in the Consolidated Statements of Cash Flows and certain Notes to 
Consolidated Financial Statements to conform to the current year presentation. In addition, as of January 1, 2018 the Company 
adopted  “ASU  2014-09”,  “ASU  2016-08”  and  “ASU  2016-10”  (the  combination  is  also  known  as  “ASC  606”  or  “New 
Revenue Standard”) using the full retrospective transition method, and the Company early adopted ASU No. 2016-02 (“ASU 
2016-02”), Leases  (Topic 842), also  referred  to  as  “ASC 842”  or  “New  Lease  Standard,”  The  Company  also  adopted 
ASU 2016-18 (“ASU 2016-18”), Statement of Cash Flows (Topic 230): Restricted Cash, also referred to as “New Cash Flow 
Presentation Standard” on January 1, 2018. 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 
regarding the impact of these recent accounting pronouncements on our Consolidated Financial Statements. 

Use of Estimates 

The preparation of Consolidated Financial Statements in conformity with United States (“U.S.”) generally accepted 
accounting principles (“U.S. GAAP”) requires the Company’s management to make judgments, assumptions, and estimates 
that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes to Consolidated Financial 
Statements.  

The accounting policies that reflect the Company’s more significant estimates and judgments and that the Company 
believes are the most critical to aid in fully understanding and evaluating its reported financial results are revenue recognition; 
capitalization of research and development assets; allowance for doubtful accounts; allowance for product warranty; 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. Those estimates could change, and as a result, actual results could differ materially from those estimates.  

Cash and Cash Equivalents 

The Company considers all highly liquid investments with an original or remaining maturity of three months or less 
at  the  time  of  purchase  to  be  cash  equivalents.  Cash  equivalents  are  stated  at  cost,  which  approximates  fair  value.  The 
Company’s cash and cash equivalents are maintained primarily in demand deposit accounts with large financial institutions 
and  in  institutional  money  market  funds.  The  Company  monitors  the  creditworthiness  of  the  financial  institutions  and 
institutional money market funds in which the Company invests its surplus funds. The Company has experienced no credit 
losses from its cash investments. 

Allowances for Doubtful Accounts  

The Company records a provision for doubtful accounts based on historical experience and a detailed assessment of 
the collectability of its accounts receivable. In estimating the allowance for doubtful accounts, the Company considers, among 

-50- 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ENERGY RECOVERY, INC. 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

other factors, the aging of the accounts receivable, its historical write-offs, the credit worthiness of each customer, and general 
economic conditions. Account balances are charged off against the allowance when the Company believes that it is probable 
that the receivable will not be recovered. Actual write-offs may be in excess of the Company’s estimated allowance. 

Short-Term and Long-Term Investments 

The  Company’s  short-term  and  long-term  investments  consist  primarily  of  investment-grade  debt  securities,  all  of 
which are classified as available-for-sale. Available-for-sale securities are carried at fair value. Amortization or accretion of 
premium or discount is included in other income (expense) on the Consolidated Statements of Operations. Changes in the 
fair  value  of  available-for-sale  securities  are  reported  as  a  component  of  accumulated  other  comprehensive  loss  within 
stockholders’ equity on the Consolidated Balance Sheet. Realized gains and losses on the sale of available-for-sale securities 
are determined by specific identification of the cost basis of each security. Short-term investments mature within 12 months 
and long-term investments mature greater than 12 months. 

Inventories 

Inventories are stated at the lower of cost (using the first-in, first-out “FIFO” method) or net realizable value. The 
Company calculates 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. 

Property and Equipment 

Property  and  equipment  is  recorded  at  cost  and  reduced  by  accumulated  depreciation.  Depreciation  expense  is 
recognized over the estimated useful lives of the assets using the straight-line method. Estimated useful lives are three to ten 
years. Certain equipment used in the development and manufacturing of ceramic components is depreciated over estimated 
useful  lives  of  up  to  10  years.  Leasehold  improvements  represent  remodeling  and  retrofitting  costs  for  leased  office  and 
manufacturing space and are depreciated over the shorter of either the estimated useful lives or the term of the lease. Software 
purchased for internal use consists primarily of amounts paid for perpetual licenses to third-party software providers and 
installation costs. Software is depreciated over the estimated useful lives of three to five years. Tangible assets acquired for 
research and development (“R&D”) activities and have alternative use are capitalized over the useful life of the acquired 
asset. Estimated useful lives are periodically reviewed, and when appropriate, changes are made prospectively. When certain 
events or changes in operating conditions occur, asset lives may be adjusted and an impairment assessment may be performed 
on the recoverability of the carrying amounts. Maintenance and repairs are charged directly to expense as incurred. 

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. 

The  Company  evaluates  the  recoverability  of  long-lived  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.

ENERGY RECOVERY, INC. 

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

Goodwill is not amortized, but is evaluated annually for impairment at the reporting unit level or when indicators of a 
potential impairment are present. The Company estimates the fair value of the reporting unit using the discounted cash flow 
and  market  approaches.  Forecast  of  future  cash  flows  are  based  on  the  Company’s  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  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 Supplemental Data,” of this Annual Report 
on Form 10-K for further discussion of intangible assets. 

Fair Value of Financial Instruments 

The Company’s financial instruments include cash and cash equivalents, restricted cash, investments in marketable 
securities, accounts receivable, accounts payable, and debt. The carrying amounts for these financial instruments reported in 
the Consolidated Balance Sheets approximate their fair values. See Note 6, “Investments and Fair Value Measurements,” 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 of fair value. 

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 Supplemental 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. 

Research and Development (“R&D”) Expense and Capitalization of R&D Assets 

R&D expense consists of costs incurred for internal projects and for technology licensed to third parties. These costs 
include the Company’s direct and research-related overhead expenses, which include salaries and other personnel-related 
expenses (including stock-based compensation), occupancy-related costs, depreciation of facilities, as well as external costs 
for equipment and supplies. Costs to acquire technologies that are utilized in research and development and that have no 
alternative future use are expensed when incurred. All R&D costs are expensed as incurred and are included in operating 
expenses. 

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.

Warranty Costs 

The Company sells products with a limited warranty for a period ranging from 18 months to five years. The Company 
accrues  for  warranty  costs  based  on  estimated  product  failure  rates,  historical  activity,  and  expectations  of  future  costs. 
Periodically, the Company evaluates and adjusts the warranty costs to the extent that actual warranty costs vary from the 
original estimates. 

Stock-based Compensation 

The Company measures and recognizes stock-based compensation expense based on the fair value measurement for 
all stock-based awards made to its 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 based on the 
Company’s 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,” for further discussion 
of stock-based compensation. 

Foreign Currency 

The Company’s reporting currency is the U.S. dollar. The functional currency of the Company’s Irish subsidiaries is 
the U.S. dollar, while the functional currency of the Company’s other foreign subsidiaries is their respective local currencies. 
The asset and liability accounts of the Company’s foreign subsidiaries are translated from their local currencies at the rates 
in effect on the balance sheet date. Revenue and expenses are translated at average rates of exchange prevailing during the 
period.  Gains  and  losses  resulting  from  the  translation  of  the  Company’s  subsidiary  balance  sheets  are  recorded  as  a 
component  of  accumulated  other  comprehensive  income  (loss).  Gains  and  losses  from  foreign  currency  transactions  are 
recorded in other income (expense) in the Consolidated Statements of Operations. 

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. The Company assesses income tax positions and records 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, the Company records 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,  the  Company  considers  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 Supplemental Data,” of this Annual Report on Form 10-K 
for further discussion of tax valuation allowances.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

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. 

The  Company’s  operations  are  subject  to  income  and  transaction  taxes  in  the  U.S.  and  in  foreign  jurisdictions. 
Significant estimates and judgments are required in determining the Company’s 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. 

Note 2 — Recent Accounting Pronouncements 

Recently adopted accounting pronouncements 

In  May  2014, the  Financial  Accounting Standards  Board  (“FASB”)  issued Accounting  Standards Update  (“ASU”) 
No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers (Topic 606), referred to as Accounting Standards 
Codification  (“ASC”)  606  (“ASC 606”)  or  the  “New  Revenue  Standard.”  ASC 606  supersedes  the  revenue  recognition 
requirements of ASC 605, Revenue Recognition, and requires entities to recognize revenue when control of promised goods 
or services is transferred to customers at an amount that reflects the consideration to which the entity expects to be entitled 
to in exchange for those goods and services. 

The update also requires more detailed disclosures to enable readers of financial statements to understand the nature, 
amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. ASC 606 permits the use 
of either the full retrospective or cumulative effect transition (modified retrospective) method upon adoption. 

In  March  and  April  2016,  the  FASB  issued  ASU  No. 2016-08  (“ASU 2016-08”),  Revenue  from  Contracts  with 
Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) and ASU No. 2016-
10  (“ASU 2016-10”),  Revenue  from  Contracts  with  Customers  (Topic 606)  Identifying  Performance  Obligations  and 
Licensing, respectively. The amendments in these updates are intended to improve the operability and understandability of 
the implementation guidance on principal versus agent considerations and to clarify two aspects of ASC 606: identifying 
performance obligations and the licensing implementation guidance, while retaining the related principles for those areas. 
The effective date and transition requirements for both ASU 2016-08 and ASU 2016-10 are the same as those for ASU 2014-
09, as referred. 

The Company adopted “ASU 2014-09”, “ASU 2016-08” and “ASU 2016-10” (the combination is also known as “ASC 
606” or “New Revenue Standard”) as of January 1, 2018 using the full retrospective transition method. To assess the impact 
of  and  to  implement  ASC 606,  the  Company  formed  a project  team,  which has operated  since  2014,  to  evaluate  internal 
processes. The Company has implemented changes to its current policies and practices, and internal controls over financial 
reporting to address the requirements of the standard. 

Water  Segment  Revenue.  Performance  obligations  identified  under  ASC  606,  are  consistent  with  deliverables 
identified under ASC 605. Revenue recognition for performance obligations accounted for under ASC 606 is consistent with 
ASC 605 given the transfer of control of the promised goods or services follows the same pattern. Adoption of ASC 606 did 
not have a material impact on the timing of revenue and expense recognition.

Oil & Gas Segment - Cost-to-Total Cost (“CTC”) Revenue. Performance obligations identified under ASC 606, are 
consistent with deliverables identified under ASC 605. Revenue recognition for performance obligations accounted for under 
ASC 606 is consistent with ASC 605 given the transfer of control of the promised goods or services follows the same pattern. 
Adoption of ASC 606 did not have a material impact on the timing of revenue and expense recognition. 

Oil & Gas Segment - License and Development Revenue. License and development revenue associated with the up-
front  non-refundable  $75.0  million  exclusivity  payment  received  in  connection  with  the  VorTeq  license  agreement  (the 
“VorTeq License Agreement”) that the Company entered into with a technology corporation (the “VorTeq Licensee”) under 
ASC 605 was recognized on a straight-line basis over the 15-year term of the license, while the two subsequent milestone 
payments of $25.0 million that could each be earned under the VorTeq License Agreement were to be recognized in full when 
achieved under milestone accounting. 

License  and  development  revenue  under  ASC 606,  which  includes  both  the  upfront  non-refundable  $75.0  million 

exclusivity payment and the two milestone payments of $25.0 million each, when determined probable, is comprised of: 

• 

• 

revenue recognition over time based on an input measure of progress based on a cost driver, which management
has determined is the best estimate of the progress made on the project during the period from inception until
full  commercialization,  for  the  amount  allocated  to  the  exclusive  Missile  (as  defined  in  Note  15,  “VorTeq

Under ASC 606, the Company concluded that the Missile license represents functional intellectual property and that 
the license is not distinct from the research and development services to be provided prior to product commercialization. The 
transaction price allocated to this combined performance obligation of a continually evolving license will be recognized over 
the estimated period required to result in full commercial launch using an input measure of progress of the cost of salaries 
and wages and travel expenses related to the project prior to full commercial launch.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

The milestone method of accounting has been eliminated under ASC 606. Instead of recognizing the full amount of 
each milestone payment as revenue in the period in which it is achieved, the Company will revise its estimate of the transaction 
price  to  include  development  milestone  payments  only  when  they  become  probable  of  achievement  and  revenue  will  be 
recognized consistent with the input measure of progress. 

The Company has concluded that its obligation to provide when and if available updates to its technology in the period 
subsequent to full commercial launch represents a performance obligation. The transaction price allocated to this stand-ready 
performance  obligation  will  be  recognized  ratably  over  the  period  commencing  after  full  commercial  launch  until  the 
expiration of the contract. 

See  Note 15,  “VorTeq  Partnership  and  License  Agreement”  for  additional  discussion  on  the VorTeq  License 

Agreement, and Note 3, “Revenues,” for further discussion of revenue recognition. 

In  February 2016,  the  FASB  issued  ASU No. 2016-02  (“ASU  2016-02”), Leases  (Topic 842):  which  supersedes 
ASC 840, Leases (Topic 840), and provides principles for the recognition, measurement, presentation and disclosure of leases 
for both lessees and lessors. The FASB has continued to clarify this guidance through the issuance of additional ASUs. The 
new standard requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the 
principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether 
lease  expense  is  recognized  based  on  an  effective  interest  method  or  on  a  straight-line  basis  over  the  term  of  the  lease, 
respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater 
than twelve months regardless of classification. Leases with a term of 12 months or less will be accounted for similar to 
existing guidance for operating leases. 

The Company early adopted ASU 2016-02 on January 1, 2018 concurrent with the Company’s adoption of the New 
Revenue  Standard  and  elected  the  available  practical  expedients.  The  adoption  of  ASU 2016-02  had  no  impact  on  the 
Company’s Consolidated Statements of Operations. The most significant impact was the recognition of right of use assets 
and  liabilities  for  operating  leases.  Adoption  of  the  standard  required  the  Company  to  recast  certain  previously  reported 
results, including the recognition of additional operating lease right of use assets and liabilities. 

In  November  2016,  the  FASB  issued  ASU 2016-18  (“ASU 2016-18”), Statement  of  Cash  Flows  (Topic 230): 
Restricted Cash, also referred to as “New Cash Flow Presentation Standard.” ASU 2016-18 is intended to reduce diversity in 
practice in the classification and presentation of changes in restricted cash on the Consolidated Statement of Cash Flows. 
ASU 2016-18 requires that the Consolidated Statement of Cash Flows explain the change in total cash and equivalents and 
amounts generally described as restricted cash or restricted cash equivalents when reconciling the beginning-of-period and 
end-of-period total amounts. The standard also requires reconciliation between the total cash and equivalents and restricted 
cash presented on the Consolidated Statement of Cash Flows and the cash and cash equivalents balance presented on the 
Consolidated Balance Sheet. ASU 2016-18 is effective retrospectively on January 1, 2018. The Company adopted ASU 2016-
18 on January 1, 2018. The Company recast its Consolidated Statements of Cash Flows for the prior periods presented based 
on  the  restricted  cash  balance  on  the  balance  sheet  date  and  has  provided  a  reconciliation  of  cash,  cash  equivalents  and 
restricted cash in Note 5, “Other Financial Information.” 

the  FASB 

In  January 2016, 

issued  ASU No. 2016-01  (“ASU 2016-01”), Financial  Instruments  -  Overall 
(Subtopic 825-10):  Recognition  and  Measurement  of  Financial  Assets  and  Financial  Liabilities. ASU 2016-01  modifies 
certain aspects of the recognition, measurement, presentation, and disclosure of financial instruments. For public entities, 
ASU 2016-01 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The 
Company adopted ASU 2016-01 on January 1, 2018. The adoption of ASU 2016-01 did not have a material impact on the 
Company’s financial position or results of operations.

In  August  2016, 

issued  ASU No. 2016-15 

(“ASU 2016-15”), Statement  of  Cash  Flows 
(Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 impacts all entities that are required 
to present a statement of cash flows under ASC 230, Statement of Cash Flows. The amendment provides guidance on eight 
specific cash flow issues. For public entities, ASU 2016-15 is effective for fiscal periods beginning after December 15, 2017 
and interim periods within those years. Adoption should be applied using a retrospective transition method to each period 
presented. The Company adopted ASU 2016-15 on January 1, 2018. The adoption of ASU 2016-15 did not have a material 
impact on the Company’s financial position or results of operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

In October 2016, the FASB issued ASU 2016-16 (“ASU 2016-16”), Income Taxes (Topic 740): Intra-Entity Transfers 
of Assets Other Than Inventory. ASU 2016-16 requires recognition of the current and deferred income tax effects of an intra-
entity asset transfer, other than inventory, when the transfer occurs, as opposed to legacy GAAP, which requires companies 
to defer the income tax effects of intra-entity asset transfers until the asset has been sold to an outside party. The income tax 
effects of intra-entity inventory transfers will continue to be deferred until the inventory is sold. ASU 2016-16 is effective on 
January 1, 2018, with early adoption permitted. The update is required to be adopted on a modified retrospective basis with 
the cumulative-effect adjustment recorded to retained earnings as of the beginning of the period of adoption. The Company 
adopted ASU 2016-16 on January 1, 2018. The adoption of ASU 2016-16 did not have a material impact on the Company’s 
financial position or results of operations. 

In  May 2017,  the  FASB  issued  ASU No. 2017-09, Compensation  –  Stock  Compensation  (Topic 718):  Scope  of 
Modification Accounting. ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-base 
payment award require an entity to apply modification accounting under ASC 718, Compensation – Stock Compensation. 
ASU 2017-09 is effective for annual periods and interim periods within those annual periods, beginning after December 15, 
2017. The Company adopted ASU 2017-09 on January 1, 2018. The adoption of ASU 2017-09 did not have an impact on the 
Company’s financial position or results of operations.

Recently issued accounting pronouncements not yet adopted 

In  June  2016,  the  FASB  issued  ASU  2016-13  (“ASU  2016-13”),  “Financial  Instruments  -  Credit  Losses”  (Topic 
326). The  FASB  issued  this  update  to  provide  financial  statement  users  with  more  decision-useful  information  about  the 
expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each 
reporting date. The amendments in this update replace the existing guidance of incurred loss impairment methodology with 
an approach that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable 
information to inform credit loss estimates. The updated guidance is effective for annual periods beginning after December 
15,  2019,  including  interim  periods  within  those  fiscal  years.  Early  adoption  of  the  update  is  permitted  in  fiscal  years 
beginning after December 15, 2018, including interim periods within those fiscal years. The Company expects to adopt this 
standard on January 1, 2020 and does not expect the adoption of ASU 2016-13 to have a material impact on its financial 
statements. 

In January 2017, the FASB issued ASU No. 2017-04 (“ASU 2017-04”), Goodwill and Other (Topic 350): Simplifying 
the Test for Goodwill Impairment. ASU 2017-04 eliminates Step 2 of the goodwill impairment quantitative test and allows 
for  the  determination  of  impairment  by  comparing  the  fair  value  of  the  reporting  unit  with  its  carrying  amount.  The 
amendments in this update should be applied on a prospective basis. For public entities which are SEC filers, this amendment 
is effective for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early 
adoption is permitted for testing dates after January 1, 2017. The Company expects to adopt this standard on January 1, 2020 
and does not expect the adoption of ASU 2017-04 to have a material impact on its financial statements.

Note 3 — Revenues  

Adoption of ASC 606, Revenue from Contracts with Customers 

On January 1, 2018, the Company adopted ASC 606 using the full retrospective transition method. The Company 
recorded a net reduction to opening retained earnings of $0.3 million as of January 1, 2016, due to the cumulative impact of 
adopting ASC 606. The impact to revenues as a result of applying ASC 606 was an increase of $6.0 million, and $3.0 million, 
for the years 2017 and 2016 respectively. 

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 payment terms vary based on the credit risk of its customer. For certain customer types, the Company 
requires payment before the products or services are delivered to the customer. The Company performs an evaluation of 
customer  credit  worthiness  on  an  individual  contract  basis  to  assess  whether  collectability  is  reasonably  assured  at  the 
inception of the contract. As part of this evaluation, the Company considers many factors about the individual customer, 
including the underlying financial strength of the customer and/or partnership consortium and the Company’s prior history 
or industry-specific knowledge about the customer and its supplier relationships. For smaller projects, the Company requires 
the  customer  to remit  payment generally within 30  to 60 days  after  product delivery. In  some  cases,  if  credit worthiness 
cannot be determined, prepayment or other security is required. 

Sales commissions are expensed as incurred when product revenue is earned. These costs are recorded within sales 

and marketing expenses. 

The following tables present the Company’s revenues disaggregated by geography, based on the shipped to addresses 

of the Company’s customers and revenue source. Sales and usage-based taxes are excluded from revenues.

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 stand-alone selling prices based on the prices charged to customers. 

With respect to termination, the Company does not have the ability to cancel the 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. 

Practical Expedients and Exemptions 

In the Water segment, the time period between when the Company transfers control of products to the customer and 
the payment for the products is, in general, less than one year and, therefore, the practical expedient with respect to a financing 
component has been adopted by the Company.  

With  respect  to  taxes,  the  Company  has  made  the  policy  election  to  exclude  taxes  from  the  measurement  of  the 

transaction price. 

The  Company  does  not disclose  the  value of  unsatisfied performance  obligations for (i)  contracts with  an original 
expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which the 
Company has the right to invoice for services performed.

The  Company  applies  the  practical  expedient  in  ASC 606,  paragraph  10-50-14,  and  does  not  disclose  information 

about remaining performance obligations that have original expected durations of one year or less. 

The Company applies the practical expedient in ASC 606 paragraph 10-65-1(f)(3), and does not disclose the amount 
of the transaction price allocated to the remaining performance obligations and an explanation of when the Company expects 
to recognize that amount of revenue for the comparative period ended December 31, 2017. 

Contract Costs 

The Company recognizes the incremental cost of obtaining contracts as an expense when incurred if the amortization 
period of the assets that the Company otherwise would have recognized is one year or less. The costs of obtaining contracts 
are included in sales and marketing expenses. 

Product and Service Revenue Recognition - Water Segment 

In the Water segment, a contract is established by a written agreement (executed sales order, executed purchase order 
or stand-alone contract) with the customer with fixed pricing, and a credit risk assessment is completed prior to the signing 
of the agreement to ensure that collectability is reasonably assured.  

The  Company  does  not  bundle  performance  obligations  in  the  Water  segment.  The  Company  identifies  each 
performance obligation separately along with its associated relative standalone selling price based on the prices and discounts 
that the Company would sell a promised good or service separately to a customer. 

Generally, performance obligations consist of delivery of products, such as PX energy recovery devices, turbochargers, 
pumps, and spare parts. Service obligation amounts which are not material, are deferred as contract liabilities until the services 
are performed.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

The transfer of control for the Company’s products follows transfer of title which typically occurs upon shipment of 
the equipment in accordance with International Commercial Terms (commonly referred to as “Incoterms”). The specified 
product performance criteria for the Company’s products pertain to the ability of the Company’s product to meet its published 
performance specifications and warranty provisions, which the Company’s products have demonstrated on a consistent basis. 
This factor, combined with historical performance metrics, provides the Company’s management with a reasonable basis to 
conclude  that  the  products  will  perform  satisfactorily  upon  commissioning  of  the  plant.  Installation  is  relatively  simple, 
requires no customization, and is performed by the customer under the supervision of the Company’s personnel. Based on 
these factors, the Company concluded that performance has been completed upon shipment when title transfers based on the 
shipping terms, and that product revenue is recognized at a point in time.  

The Company does not provide its customers with a right of product return; however, the Company will accept returns 
of products that are deemed to be damaged or defective when delivered that are covered by the terms and conditions of the 
product warranty. Product warranty is provided consistent with the industry and is considered to be an assurance warranty, 
not a separate performance obligation. Product returns and warranty charges have not been significant. 

Revenue  allocable  to  the  Company’s  product  is  limited  to  the  amount  that  is  not  contingent  upon  the  delivery  of 
additional items or meeting specified performance conditions. The Company adheres to consistent pricing in the stand-alone 
sale of products and services. 

For  large  projects,  stand-alone  contracts  are  utilized.  For  these  contracts,  consistent  with  industry  practice,  the 
Company’s customers typically require their suppliers, including the Company, to accept contractual holdback provisions 
(also referred to as a retention payment) whereby the final amounts due under the sales contract are remitted over extended 
periods of time or alternatively, stand-by letters of credit are issued. These retention payments are generally 10% or less of 
the total contract amount and are due and payable upon the passage of time, generally up to 24 to 36 months from the date of 
product delivery. These retention payments are generally replaced by bank guarantees which have had no history of being 
exercised, and they align with the product warranty period. Given that they are not material in the context of the contract, 
they are not considered to be a financing component. The Company has no performance obligation and they are recorded as 
contract assets. 

Shipping and handling charges billed to customers is a pass-through from the freight forwarder and is included in 

product revenue. The cost of shipping to customers is included in cost of revenue. 

Cost-to-Total Cost (“CTC”) Revenue Recognition - Oil & Gas Segment 

IsoBoost and IsoGen systems are highly engineered, customized solutions that are designed and manufactured over an 
extended period of time and are built specifically to meet a customer’s specifications. Given the facts and circumstances of 
these projects, the Company concluded that the CTC method of accounting is appropriate for IsoBoost and IsoGen systems. 
In the event that a purchase order for an IsoBoost or IsoGen system does not meet these facts and circumstances, then the 
CTC method of accounting does not apply. The Company had one CTC contract for IsoBoost turbochargers in fiscal years 
2016  through  2018,  which  was  completed  in  2018,  and  last  units  were  shipped  in  the  first  quarter  of  2019.  A  standard 
assurance type warranty was provided. 

Revenue from fixed price contracts is recognized with progress measured in the ratio of costs incurred to estimated 
final costs. Contract costs include all direct material and labor costs related to contract performance. Pre-contract costs with 
no future benefit were expensed in the period in which they were incurred. Since the financial reporting of these contracts 
depends on estimates, which are assessed continually during the term of the contract, recognized revenues and profit are 
subject to revisions as the contract progresses to completion. Revisions in profit estimates are reflected in the period in which 
the facts that give rise to the revisions become known, using the cumulative catchup method. If material, the effects of any 
changes in estimates are disclosed in the notes to the consolidated financial statements. When estimates indicate that a loss 
will be incurred on a contract, a provision for the expected loss is recorded in the period in which the loss becomes evident. 
No loss has been incurred to date. Revenue is recognized only to the extent costs have been recognized in the same period.

License and Development Revenue Recognition - Oil & Gas Segment 

License and development revenue is comprised of revenue recognition over time of the upfront non-refundable $75.0 
million exclusivity fee received in connection with the VorTeq License Agreement, as well as the revenue recognition over 
time of the two milestone payments of $25.0 million each when uncertainty of receipt is resolved and receipt of each milestone 
payment is considered probable.  

The VorTeq License Agreement is comprised of a 15-year exclusive license for the Company’s VorTeq technology 
(“VorTeq”). In performing the obligations under the license, the Company provides research and development services to 
commercialize the technology in accordance with the Key Performance Indicators (“KPIs”), defined in the VorTeq License 
Agreement.  After  commercialization  is  achieved,  payments  will  be  received  for  the  supply  and  servicing  of  certain 
components of the VorTeq. All payments are non-refundable. See 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 further details. 

The Company recognizes license and development revenue in accordance with ASC 606. Revenue is recognized when 
control of the promised goods or services is transferred to customers. Stand-alone selling price was established at the inception 
of the VorTeq License Agreement by taking the transaction to market on a non-exclusive basis, and pricing in an exclusivity 
premium. Since the VorTeq License Agreement included an up-front non-refundable payment at the inception of the VorTeq 
License Agreement and future products and services are provided after initial commercialization, the Company completed an 
analysis and concluded that there was no material right included in the pricing of the VorTeq License Agreement. 

Performance obligations, such as the exclusive license to the Missile technology and upgrades prior to and subsequent 
to the date of full commercial launch, have been identified. Value has been allocated to the performance obligations and 
revenue is recognized over time based on the input measure of progress of the cost of salaries and wages related to the project 
prior to full commercialization, and ratably for the unspecified upgrades for the period subsequent to full commercialization 
until the expiration of the VorTeq License Agreement.  

Once  commercial  launch  is  achieved  and  cartridges  are  provided  under  the  contract,  revenue  from  those  royalty 
payments will be recognized in accordance with ASC 842, with the Company as the lessor.  It is expected that the cartridge 
leases will be classified as operating leases, and lease revenue will be recognized as earned.

Note 4 — Income Per Share  

Net income is divided by the weighted average number of common shares outstanding during the year to calculate 

basic net income per common share. Basic earnings per share exclude any dilutive effects of stock options and RSUs. 

Diluted net income per common share reflects the potential dilution that would occur if outstanding stock options to 
purchase common stock were exercised for common stock, using the treasury stock method, and the common stock underlying 
outstanding restricted award was issued. Diluted earnings per share for the years ended December 31, 2018, 2017 and 2016, 
includes the dilutive effects of stock options and RSUs. Certain common stock issuable under stock options and RSUs have 
been omitted from the 2018, 2017 and 2016 diluted net income per share calculations because their inclusion is considered 
anti-dilutive.

The Company monitors investments for other-than-temporary impairment. It was determined that unrealized gains and 
losses at December 31, 2018 and 2017, are temporary in nature, because the changes in market value for these securities 
resulted from fluctuating interest rates, rather than a deterioration of the credit worthiness of the issuers. The Company is 
unlikely to experience gains or losses if these securities are held to maturity. In the event that the Company disposes of these 
securities before maturity, it is expected that the realized gains or losses, if any, will be immaterial.

Fair Value of Financial Instruments 

The Company follows the authoritative guidance for fair value measurements and disclosures that, among other things, 
defines fair value, establishes a consistent framework for measuring fair value, and expands disclosure for each major asset 
and liability category measured at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price 
that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. As 
such, fair value is a market-based measurement that should be determined based on assumptions that market participants 
would use in pricing an asset or liability. 

Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities; 
Level 2 — Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and 
Level 3 — Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its 
own assumptions that market participants would use in pricing. 

The carrying values of cash and cash equivalents, restricted cash, accounts receivable, un-billed receivables, cost and 
estimated earnings in excess of billings, accounts payable, and other accrued expenses approximate fair value due to the 
short-term maturity of those instruments. For the Company’s investments in available-for-sale securities, if quoted prices in 
active markets for identical investments are not available to determine fair value (Level 1), then the Company uses quoted 
prices for similar assets or inputs other than quoted prices that are observable either directly or indirectly (Level 2). The 
investments included in Level 2 consist of corporate notes and bonds, municipal notes and bonds and U.S. Treasury securities.

Loans and Stand-by Letters of Credit 

Loan and Pledge Agreement 

On January 27, 2017, the Company entered into a loan and pledge agreement (the “Loan and Pledge Agreement”) with 
a financial institution (“Financial Institution 2”). The Loan and Pledge Agreement provides for a committed revolving credit 
line  of $4.0  million.  The Loan  and  Pledge 
revolving  credit 
line  of $16.0  million and  an  uncommitted 
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 March 30,  2018 to  extend  the  termination  date  of  the Loan  and  Pledge 
Agreement from March 31, 2018 to March 31, 2020. No other provisions of the Loan and Pledge Agreement were amended 
at that time. 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 Financial Institution 2 are deducted 
from the total revolving credit line.

Stand-by Letters of Credit 

In  connection  with  a  previous  loan  agreement,  entered  into  in  June  2012  and  terminated  in  June  2017,  Financial 
Institution 1 issued stand-by letters of credit to the Company that were subject to customary fees and expenses for issuance 
or renewal. The unused portion of the credit facility was subject to a facility fee in an amount equal to 0.25% per annum of 
the average unused portion of the revolving line. The loan agreement required the Company to maintain a cash collateral 
balance equal to 101% of all outstanding advances and all outstanding stand-by letters of credit collateralized by the line of 
credit. With the termination of the loan agreement, the cash collateral requirement was increased to 105% on all stand-by 
letters of credit and corporate credit cards at Financial Institution 1. 

In  September  2016,  Financial  Institution 2  issued  stand-by  letters  of  credit  to  the  Company  that  were  subject  to 
customary fees and expenses for issuance or renewal. Initially, Financial Institution 2 required a cash collateral equal to the 
full outstanding amount of the stand-by letters of credit until the Loan and Pledge Agreement was put in place on January 27, 
2017. As of that same date, this cash collateral requirement was removed when the Company entered into a loan and pledge 
agreement with Financial Institution 2 (see Loan and Pledge Agreement above) and replaced with pledged U.S. Investments 
held at Financial Institution 2 equal to the full outstanding amount of the stand-by letters of credit. These stand-by letters of 
credit are subject to fees, in an amount equal to 0.7% per annum of the face amount of the letter of credit, that are payable 
quarterly and are non-refundable. 

In  October  2016,  the  Company  entered  into  stand-by  letters  of  credit  with  a  financial  institution  (“Financial 
Institution 3”). Financial Institution 3’s stand-by letters of credit were secured by a cash collateral balance required equal to 
the full outstanding amount of the stand-by letters of credit.

Note 9 — Commitments and Contingencies  

Operating Lease Obligations 

The Company leases office facilities and equipment under operating leases that expire on various dates through 2028. 

In April 2018, the Company renegotiated the lease of approximately of 170,000 square feet of space in San Leandro, 
California, with the lessor (“New Doolittle Lease”). The New Doolittle Lease is effective from April 2018 through December 
2028 and has a renewal term of one additional period of five years. The initial monthly rent is approximately $135 thousand 
with an annual increase of 3% and a total of nine months of rent abatement.  Under the new lease standard, ASC 842, which 
was early-adopted by the company in 2018, the New Doolittle Lease was accounted for as a modification with changes in 
lease term and consideration. As a result, the Company re-measured the lease liability using the updated discount rate using 
secured borrowing discount rate and revised lease payments and recognized the amount of $10.4 million as an increase to the 
lease liability, with a corresponding adjustment to the right-of-use asset.   

In October 2017, the Company entered into a sublease agreement for office space in Houston, Texas. The sublease 

agreement is for a term of 3 years commencing in November 2017.

Guarantees 

The Company enters into indemnification provisions under its agreements with other companies in the ordinary course 
of business, typically with customers. Under these provisions, the Company generally indemnifies and holds harmless the 
indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities, generally 
limited to personal injury and property damage caused by the Company’s employees at a customer’s desalination plant in 
proportion to the employee’s percentage of fault for the accident. Damages incurred for these indemnifications would be 
covered by the Company’s general liability insurance to the extent provided by the policy limitations. The Company has not 
incurred  material  costs  to  defend  lawsuits  or  settle  claims  related  to  these  indemnification  agreements.  As  a  result,  the 
estimated  fair  value  of  these  agreements  is  not  material.  Accordingly,  the  Company  had  no  liabilities  recorded  for  these 
agreements as of December 31, 2018 and 2017. 

In  certain  cases,  the  Company  issues  warranty  and  product  performance  guarantees  to  its  customers  for  amounts 
generally equal to 10% or less of the total sales agreement to endorse the execution of product delivery and the warranty of 
design work, fabrication, and operating performance of our devices. These guarantees are generally stand-by letters of credit 
that typically remain in place for periods ranging up to 36 months. All stand-by letters of credit at December 31, 2018 and 
2017, were $8.8 million and $10.4 million, respectively. 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 Supplemental Data,” of this Annual Report

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.  

The Company has evaluated the impact of the new global intangible low taxed income (GILTI) and has concluded that 

the impact to the Company of the GILTI is immaterial. 

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 Q2 2018. This election resulted in a deferred tax asset related to tax expense previously 
recorded on earnings and profits under the Tax Act on deferred revenue not yet recognized under US GAAP. The 2018 tax 
results also reflect an $800k tax benefit from stock based compensation tax deductions in excess of the related book expense. 
For more details on the impact of tax credits and other factors that impact the Company’s annual income tax expense, please 
see the reconciliation of the statutory federal income tax rate to the effective tax rate table below.  

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. For more details on the impact of tax credits and other factors that impact 
the  Company’s  annual  income  tax  expense,  please  see  the  reconciliation  of  the  statutory  federal  income  tax  rate  to  the 
effective tax rate table below.

Consolidated Financial Statements in Part II, Item 8, “Financial Statements and Supplemental Data” of this Annual Report on Form 10K, 
the balances for the years ended 2017 and 2016 are recast. 

The Company had gross deferred tax assets of approximately $23.3 million and $13.6 million at December 31, 2018 
and 2017, respectively, relating principally to accrued expenses and tax effects of net operating loss and tax credit carry-
forwards. In asserting the recoverability of deferred tax assets, management considers whether it is more likely than not that 
the assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable 
income during the periods in which those temporary differences become deductible. 

The Company assesses the available positive and negative evidence to estimate if sufficient future taxable income will 
be generated to use the existing 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. A significant piece of objective positive evidence evaluated was the cumulative 
profit incurred in the U.S. and the cumulative losses incurred in Ireland over the three-year period ended December 31, 2018. 

On the basis of this evaluation, as of December 31, 2018, the Company recognizes all of its U.S. federal and state 
deferred tax assets with the exception that the Company continues to maintain a valuation allowance on its California R&D 
credit carryovers of approximately $1.7 million. The Company will maintain a valuation allowance on its California R&D 
credit carryovers because it is more likely than not that the Company will continue to annually generate more California R&D 
tax credits than it utilizes, resulting in no net reduction of credits. The Company’s policy with respect to California R&D 
credits is that they are utilized on a last-in first-out basis.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

In addition, as of December 31, 2018, the Company is reporting a full valuation allowance on its Irish entity’s deferred 
tax assets totaling $1.2 million. The valuation allowance represents a provision for uncertainty as to the realization of tax 
benefits from these deferred income tax assets. The Company will continue to evaluate the tax benefit uncertainty and will 
adjust, if warranted, the valuation allowance in future periods to the extent that the Company’s deferred income tax assets 
become more likely than not to be realizable. 

The Company continues to assert that the accumulated foreign earnings of its subsidiaries in Spain and Canada are 
permanently reinvested. Due to the Tax Act, any future repatriation of the earnings of its subsidiaries in Spain and Canada 
would not be subject to U.S. federal income tax. The Company has estimated that the foreign withholding taxes and U.S. 
state income taxes related to a potential future repatriation of these earnings would be immaterial.

The net operating loss carryforwards, if not utilized, will begin to expire in 2019 for Federal, and 2031 for California. 
Utilization  of  the  net  operating  loss  carryforward  may  be  subject  to  a  substantial  annual  limitation  due  to  the  ownership 
change  limitations  provided  by  the  U.S.  Internal  Revenue  Code  (“IRC”)  and  similar  California  provisions.  The  annual 
limitation will result in the expiration of the net operating loss carryforwards before utilization. The Company has estimated 
the amount which may ultimately be realized and recorded deferred tax assets accordingly. The Ireland net operating loss 
carryforwards does not have an expiration date.

As  of  December 31,  2018,  the  Company  had  $1.2 million  of  unrecognized  tax  benefits,  $0.6 million  of  which,  if 

recognized, would affect our effective tax rate. 

The Company adopted the accounting policy that interest and penalties are classified as part of its income taxes. There 

are no accrued interest or penalties associated with any unrecognized tax benefits. 

There  are  currently  no  examinations  for  Federal,  California  taxing  authorities,  and  foreign  tax  authorities.  The 
Company believes that, as of December 31, 2018, the gross unrecognized tax benefits will not materially change in the next 
twelve months. The Company believes that it has adequately provided for any reasonably foreseeable outcomes related to 
any tax audits and that any settlement will not have a material adverse effect on the consolidated financial position or results 
of operations. However, there can be no assurances as to the possible outcomes. 

Note 11 — Stockholder’s Equity  

Preferred Stock 

The Company has the authority to issue 10,000,000 shares of $0.001 par value preferred stock. The Board of Directors 
has the authority, without action by the Company’s stockholders, to designate and issue shares of preferred stock in one or 
more series. The Board of Directors is also authorized to designate the rights, preferences, and voting powers of each series

stock, and delaying or preventing a change in control of the Company without further action by the Company’s stockholders. 
To  date,  the  Board  of  Directors  has  not  designated  any  rights,  preferences,  or  powers  of  any  preferred  stock,  and  as  of 
December 31, 2018 and 2017, no shares of preferred stock were issued or outstanding. 

Common Stock 

The Company has the authority to issue 200,000,000 shares of $0.001 par value common stock. Subject to the preferred 
rights of the holders of shares of any class or series of preferred stock as provided by the Board of Directors with respect to 
any such class or series of preferred stock, the holders of the common stock shall be entitled to receive dividends, as and 
when declared by the Board of Directors. In the event of any liquidation, dissolution, or winding up of the Company, whether 
voluntary or involuntary, after the distribution or payment to the holders of shares of any class or series of preferred stock as 
provided by the Board of Directors with respect to any such class or series of preferred stock, the remaining assets of the 
Company  available  for  distribution  to  stockholders  shall  be  distributed  among  and  paid  to  the  holders  of  common  stock 
ratably in proportion to the number of shares of common stock held by them. 

At  December 31,  2018,  59,396,020  shares  were  issued  and  53,940,085  shares  were  outstanding.  At  December 31,

Stock Repurchase Program 

The  Company  accounts  for  stock  repurchases  using  the  cost  method.  The  aggregate  cost  includes  fees  charged  in 

connection with acquiring the outstanding common stock. 

On March 7, 2018, the 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  the  Company’s  outstanding  common 
stock (the “March 2018 Authorization”). Under the March 2018 Authorization, purchases of shares of common stock may be 
made through September 30, 2018, 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 March 2018 Authorization does not 
obligate the Company 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 September 30, 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,  the  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 the Company’s outstanding common 
stock  through  September 30,  2017  (the  “March  2017  Authorization”).  As  of  December 31,  2017,  541,177 shares,  at  an 
aggregate cost of $4.3 million had been repurchased under the March 2017 Authorization.  

In  January  2016,  the  Board  of  Directors  authorized  a  stock  repurchase  program  under  which  the  Company,  at  the 
discretion of management, could repurchase up to $6.0 million in aggregate cost of the Company’s outstanding common 
stock through June 30, 2016 (the “January 2016 Authorization”). In May 2016, the Board of Directors rescinded the January 
2016  Authorization  and  authorized  a  new  stock  repurchase  program  under  which  the  Company,  at  the  discretion  of 
management, could repurchase up to $10.0 million in aggregate cost of the Company’s outstanding common stock through 
October 31,  2016  (the  “May  2016  Authorization”).  At  December  31,  2016,  673,700 shares,  at  an  aggregate  cost  of 
$4.1 million,  had  been  repurchased  under  the  January  2016  Authorization  and  568,500 shares,  at  an  aggregate  cost  of 
$5.3 million, had been repurchased under the May 2016 Authorization. The May 2016 Authorization expired in October 2016 
and there was no repurchase authorization in place at December 31, 2016. 

Under the Company’s stock repurchase programs, from March 2012 through December 31, 2018, the Company spent 
an aggregate $30.3 million to repurchase 5.5 million shares. In addition to repurchases under the Company’s stock repurchase 
programs,  during  the  years  ended  December 31,  2018,  and  2017,  the  Company  spent $0.2 million  and  $0.3  million 
respectively, to settle employee tax withholding obligations due upon the vesting of RSUs and withheld an equivalent value 
of shares from the shares provided to the employees upon vesting.  

Note 12 — Stock-Based Compensation 

Stock Option Plans 

In June 2016, the stockholders approved the 2016 Incentive Plan (the “2016 Plan”), that permits the grant of stock 
options, stock appreciation rights (“SARs”), restricted stock (“ RSUs”), performance units, performance shares, and other 
stock-based awards to employees, officers, directors, and consultants. Prior to the approval of the 2016 Plan, the Company 
maintained the Amended and Restated 2008 Equity Incentive Plan (the “2008 Plan”). Stock option awards granted under the 
Plan and the 2008 Plan, generally vest over four years and expire no more than 10 years after the date of grant. Subject to 
adjustments, as provided in the 2016 Plan, the number of shares of common stock initially authorized for issuance under the 
2016  Plan  was  4,441,083  shares  (which  consist  of  3,830,000  new  share  awards  plus  611,083  share  awards  that  were 
authorized and unissued under the 2008 Plan) plus up to 7,635,410 shares that were set aside for awards granted under the 
2008 Plan that are subsequently forfeited. The 2016 Plan supersedes all previously issued stock incentive plans (including 
the 2008 Plan) and is currently the only available plan from which awards may be granted. 

Shares available for grant under the Plan were 2,603,183 shares and 3,945,653 shares at December 31, 2018 and 2017, 

respectively.

The Company estimates forfeitures at the time of grant and revises those estimates periodically in subsequent periods 
if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures 
and records stock-based compensation expense only for those awards that are expected to vest. All stock-based payment 
awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting 
periods.  If  the  Company’s  actual  forfeiture  rate  is  materially  different  from  its  estimate,  the  stock-based  compensation 
expense could be significantly different from what the Company has recorded in the current period. 

The estimated forfeiture rates used in determining the expense in the table above are presented in the following table.

The fair value of stock options granted to employees is based on the Black-Scholes option pricing model. To determine 
the inputs for the Black-Scholes option pricing model, the Company is required to develop several assumptions, which are 
highly subjective. The Company determines these assumptions as follows:  

Expected Term: The Company uses its historical data to determine the expected term of options based on historical 
exercise data. As there was no historical exercise data for non-employee directors, the Company determines the expected 
term based on the simplified method.  

Expected Volatility: The Company determines expected volatility based on its historical data and the corresponding 

expected term that was determined using the Company’s historical exercise data. 

Risk-Free  Interest  Rate:  The  risk-free  rate  is  based  on  U.S.  Treasury  issues  with  remaining  terms  similar  to  the 

expected term on the stock options granted. 

Dividend Yield: The Company has never declared or paid any cash dividends and do not plan to pay cash dividends in 

the foreseeable future; therefore, the Company uses an expected dividend yield of zero in the valuation model.

Note 13 — Business Segment  

The Company is an energy solutions provider to industrial fluid flow markets worldwide. The Company manufactures 
and sells high-efficiency ERDs and pumps as well as related products and services. The Company’s chief operating decision-
maker (“CODM”) is the chief executive officer (“CEO”). 

The  Company’s  reportable  operating  segments  consist  of  the  Water  segment  and  the  Oil  &  Gas  segment.  These 
segments are based on the industries in which the products are sold, the type of energy recovery device sold, and the related 
products and services. The Water segment consists of revenue associated with products sold for use in reverse osmosis water 
desalination, as well as the related identifiable expenses. The Oil & Gas segment consists of product revenue associated with 
products sold for use in gas processing, chemical processing, and hydraulic fracturing and license and development revenue 
associated with hydraulic fracturing, as well as related identifiable expenses. Operating income for each segment excludes 
other income and expenses and certain expenses managed outside the operating segment. Costs excluded from operating 
income include various corporate expenses such as income taxes and other separately managed general and administrative 
expenses not related to the identified segments. Assets and liabilities are reviewed at the consolidated level by the CODM 
and are not accounted for by segment. The CODM allocates resources to and assesses the performance of each operating 
segment using information about its revenue and operating income (loss). 

The summary of financial information by segment is presented in the following tables.

Product Revenue - Customer Concentration 

Product 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. 

License and Development 

One international Oil & Gas segment customer accounts for 100% of the Company’s license and development revenue 

for the years ended December 31, 2018, 2017 and 2016. 

Customers 

The  Company’s  accounts  receivable  is  derived  from  sales  to  customers  located  around  the  world.  The  Company 
generally does not require collateral to support customer receivables, but frequently requires export letters of credit securing 
payment. The Company performs ongoing evaluations of its customers’ financial condition and periodically reviews credit 
risk associated with receivables. An allowance for doubtful accounts is determined with respect to receivable amounts that 
we have determined to be doubtful of collection using specific identification of doubtful accounts and an aging of receivables 
analysis based on invoice due dates. Actual collection losses may differ from the Company’s estimates, and such differences 
could be material to the financial position, results of operations, and cash flows. Uncollectible receivables are written off 
against  the  allowance  for  doubtful  accounts  when  all  efforts  to  collect  them  have  been  exhausted,  while  recoveries  are 
recognized when they are received.

Note 15 — VorTeq Partnership and License Agreement  

The Company’s VorTeq technology enables oilfield service hydraulic fracturing operators to isolate their high-pressure 
hydraulic fracturing pumps from fracturing fluid thereby reducing operating and capital costs. In 2014, the Company 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 20 VorTeq Missiles (defined below) for a period of up to five 
years following commercialization. 

On October 14, 2015, the Company and the VorTeq Licensee entered into the VorTeq License Agreement, which 
provides the VorTeq Licensee with exclusive worldwide rights to the Company’s VorTeq technology for use in hydraulic 
fracturing onshore applications. The VorTeq License Agreement provides an exception for Liberty’s contractual rights to 
utilize the VorTeq. In performing the obligations under the agreement, the Company provides research and development 
services  to  commercialize  the  technology  in  accordance with  the  KPIs,  defined  in  the  VorTeq License Agreement.  After 
commercialization is achieved, royalty payments will be received for the supply and servicing of cartridges. All payments 
are non-refundable.  

The VorTeq is made up of Pressure Exchanger cartridges, housed in a high-pressure manifold (the “Missile”) though 
which a motive fluid is used to pressurize hydraulic fracturing fluid, which is processed and sent down the well bore. The 
VorTeq License Agreement includes up to $125.0 million in upfront consideration paid in stages: (i) a $75.0 million non-
refundable  upfront  exclusivity  payment;  and  (ii)  two  milestone  payments  of  $25.0  million  each  upon  achievement  of 
successful tests in accord with KPIs specified in the VorTeq License Agreement (“Milestone Payment 1 and 2”). Milestone

Licensee’s customer’s live wells. The achievement of each milestone and the receipt of each of the related payments are 
subject to a high degree of uncertainty. 

After initial commercialization, the VorTeq Licensee will begin paying ongoing recurring royalty fees to the Company 
for supply and service of the cartridges based on the number of VorTeqs in operation which is subject to the greater of a 
minimum adoption curve or the adoption rate of the technology. During the period, from initial commercialization to full 
commercialization, the technology will be deployed commercially; and through continuous improvement and cost refinement, 
the efficiency and effectiveness of the product will fully stabilize. The exclusive nature of the agreement terminates if the 
VorTeq Licensee does not meet the specified minimum adoption curves. In the event the Company is not able to achieve full 
commercialization under the terms of the VorTeq License Agreement, the exclusivity right of the VorTeq Licensee under the 
VorTeq License Agreement continues throughout the term. 

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 of revenue recognition. 

Note 16 — Litigation  

The  Company  is  named  in  and  subject  to  various  proceedings  and  claims  in  connection  with  our  business.  The 
Company is contesting the allegations in these claims, and the Company believes that there are meritorious defenses in each 
of these matters. The outcome of matters the Company has been, and currently are, involved in cannot be determined at this 
time, and the results cannot be predicted with certainty. There can be no assurance that these matters will not have a material 
adverse effect on our results of operations in any future period and a significant judgment could have a material adverse 
impact on our financial condition, results of operations and cash flows. The Company may in the future become involved in 
additional litigation in the ordinary course of its business, including litigation that could be material to its business. 

The Company considers all claims on a quarterly basis and based on known facts assesses whether potential losses are 
considered reasonably possible, probable and estimable. Based upon this assessment, the Company then evaluates disclosure 
requirements and whether to accrue for such claims in its consolidated financial statements. The Company records a provision 
for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. 
These provisions are reviewed at least quarterly and adjusted to reflect the impacts of negotiations, settlements, rulings, advice 
of legal counsel and other information and events pertaining to a particular case. 

On September 10, 2014, the Company terminated the employment of its Senior Vice President, Sales, Borja Blanco, 
on the basis of breach of duty of trust and conduct leading to conflict of interest. On October 24, 2014, Mr. Blanco filed a 
labor claim against ERI Iberia in Madrid, Spain, challenging the fairness of his dismissal and seeking compensation (“Case 
1”). A hearing was held on November 13, 2015, after which the labor court ruled that it did not have jurisdiction over the 
matter. Mr. Blanco appealed and the appeals court reversed the labor court’s finding and instructed the labor court to make a 
ruling on the merits on November 21, 2017. On February 14, 2018, the Company received notice that the labor court issued 
a ruling in favor of Mr. Blanco declaring the termination an unjustified dismissal and ordered the Company to pay a dismissed 
severance. The Company appealed the decision on February 21, 2018.  The Company denies any allegations of wrongdoing 
and intends to continue to vigorously defend against this lawsuit.  Based on currently available information and review with 
outside counsel, the Company has estimated and accrued a potential loss. 

On November 24, 2014, Mr. Blanco filed a second action based on breach of contract theories in the same court as 
Case 1 (“Case 2”), but the cases are separate. In Case 2, Mr. Blanco seeks payment of an unpaid bonus, stock options, and 
non-compete compensation. The court ruled that this case is stayed until a final ruling is issued in Case 1. The Company 
denies any allegations of wrongdoing and intends to continue to vigorously defend against this lawsuit. Based on currently 
available  information  and  review  with  outside  counsel,  the  Company  has  determined  that  an  award  to  Mr. Blanco  is  not 
probable. While a loss may be reasonably possible, an estimate of loss, if any, cannot reasonably be determined at this time.

Item 9 — Changes in and Disagreements with Accountants on Accounting and Financial Disclosure 

On  April  13,  2018,  the  Company’s  principal  accountant,  BDO  USA,  LLP,  was  dismissed.  Such  dismissal  was 
recommended  and  approved  by  the  Audit  Committee  of  the  Board  of  Directors  (the  “Audit  Committee”).  The  Audit 
Committee  engaged  Deloitte  &  Touche  LLP  as  the  Company’s  new  principal  accountant  on  May  2,  2018.   During  the 
preceding two years, BDO USA, LLP’s reports on financial statement did not contain an adverse opinion or a disclaimer of 
opinion, was not qualified or modified as to uncertainty, audit scope, or accounting principles. There were no disagreements 
with BDO USA, LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope 
or procedure within the Company’s two most recent fiscal years and any subsequent interim periods preceding the former 
principal accountant’s dismissal. 

Item 9A — Controls and Procedures 

Evaluation of Disclosure Controls and Procedures 

Our management has evaluated, with the participation of our Chief Executive Officer and Chief Financial Officer, the 
effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities 
Exchange Act of 1934, or “Exchange Act”) as of the end of the period covered by this Annual Report on Form 10-K. Based 
on  that  evaluation,  our  Chief  Executive  Officer  and  Chief  Financial  Officer  have  concluded  that,  as  of  such  date,  our 
disclosure controls and procedures were effective to ensure that information we are required to disclose in reports that we file 
or submit under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified in 
Securities  and  Exchange  Commission  rules  and  forms  and  that  such  information  is  accumulated  and  communicated  to 
management as appropriate to allow for timely decisions regarding required disclosure. 

Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives, and 
our Chief Executive Officer and Chief Financial Officer have concluded that these controls and procedures are effective at 
the  “reasonable  assurance”  level.  Our  management,  including  the  Chief  Executive  Officer  and  Chief  Financial  Officer, 
believes  that  a  control  system,  no  matter  how  well  designed  and  operated,  cannot  provide  absolute  assurance  that  the 
objectives of the control system are met, and that no evaluation of controls can provide absolute assurance that all control 
issues and instances of fraud, if any, within a company have been detected. 

Management’s Annual Report on Internal Control Over Financial Reporting and Attestation Report of the Registered 
Public Accounting Firm 

Management’s Report on Internal Control Over Financial Reporting 

Management is responsible for establishing and maintaining adequate internal control over the Company’s financial 
reporting.  Management  assessed  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  as  of 
December 31,  2018.  In  making  this  assessment,  management  used  the  criteria  set  forth  by  the  Committee  of  Sponsoring 
Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). Based on the 
assessment using those criteria, management concluded that, as of December 31, 2018, our internal control over financial 
reporting was effective. 

Attestation Report of the Registered Public Accounting Firm 

The Company’s independent registered public accountants, Deloitte & Touche LLP, audited the Consolidated Financial 
Statements included in this Annual Report on Form 10-K and have issued an audit report on the Company’s internal control 
over  financial  reporting.  The  report  on  the  audit  of  internal  control  over  financial  reporting  appears  in  Part II,  Item 8, 
“Financial Statements and Supplementary Data,” in this Annual Report on Form 10-K. 

Changes in Internal Control Over Financial Reporting 

There  were  no  changes  in  our  internal  control  over  financial  reporting  that  occurred  during  our  most  recent  fiscal 
quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

EXPLANATORY NOTE 

This  Amendment  No.  1  on  Form  10-KA  (the  “Amendment”)  of  Energy  Recovery  Inc  (“the  Company”)  amends  the 
Company’s Annual Report on Form 10-K for the year ended December 31, 2018, originally filed with the Securities and 
Exchange Commission on March 7, 2019 (the “Original Report”).  

This Amendment is being filed solely to correct two administrative errors on the cover page of the Original Report with 
respect to the aggregate market value of the voting stock held by non-affiliates at June 30, 2018 and the number of shares 
outstanding of the Company’s common stock as of February 28, 2019. The correct amount of aggregate market value of the 
voting stock held by non-affiliates at June 30, 2018 was approximately $284 million. The correct number of shares of the 
Company’s common stock outstanding as of February 28, 2019, was 54,107,060.  

This Amendment No. 1 speaks as of the original filing date of the Form 10-K, does not reflect events that may have occurred 
subsequent to the original filing date, and does not modify or update in any way disclosures made in the Original Report. No 
other changes have been made to the Original Report. 

As required by Rule 12b-15 of the Securities Exchange Act of 1934, as amended, this Amendment contains new certifications 
by  the  Company’s  principal  executive  officer  and  principal  financial  officer,  which  are  being  filed  as  exhibits  to  the 
Amendment. Because the Amendment includes no financial statements, the Company is not including certifications pursuant 
to Section 906 of the Sarbanes-Oxley Act of 2002.
