Overview

PART I

We offer converged solutions for next-generation centralized, distributed and virtualized architectures for cable broadband, fixed-line broadband and
wireless networks. Our innovative products enable customers to cost-effectively and dynamically increase network speed, add bandwidth capacity and new
services for consumers and enterprises, reduce network complexity and reduce operating and capital expenditures.

We focus our development efforts on innovation and being the first to market with new products at each generational shift in network technology. For
example, we pioneered the use of a software-centric approach to leverage the programmability of field programmable gate arrays, or FPGAs, and general-
purpose  processors  for  use  in  the  cable  industry.  In  addition,  we  believe  we  were  the  first  to  provide  each  of  the  following  to  our  customers:  a  solution
enabling cable service providers to deliver Internet Protocol, or IP, voice, digital video and data over a single port; a solution enabling cable service providers
to  deliver  multi-gigabit  speeds  to  their  subscribers;  and  a  remote  node  solution  to  enable  distributed  broadband  cable  access  at  gigabit  speeds.  With  our
recently launched wireless products, including our Apex™ Strand and Small Cell Management System, our mobile edge computing (MEC) solution, and our
Axyom™ Small Cell Core, we believe that we are ahead of the market in enabling mobile network service providers to deliver increased bandwidth and new
services to their subscribers.

We have created a software-centric, multi-service portfolio based on our Axyom software which enables a broad range of core and access network
functions for fixed and wireless networks. These networks share a common set of core and access network functions that enable network services such as
subscriber management, session management, transport security and radio frequency, or RF, management. Our Axyom software architecture allows each of
these  network  functions  to  be  provided  and  controlled,  integrated  or  combined  together,  in  a  building  block-style  fashion  with  the  segments  of  software
responsible for each other network function. This allows us to offer network architectures that can be efficiently and rapidly tailored to meet each customer’s
specific requirements, both as they exist at the time of initial implementation and as they evolve over time. While we initially focused on providing solutions
for cable service providers due to our founders’ experience in the cable industry, the commonalities between new fixed and wireless network architectures
have allowed us to leverage our existing Axyom software and to expand our solutions into the wireless and fixed communications markets.

We  offer  a  scalable  solution  that  can  meet  the  evolving  bandwidth  needs  of  our  customers  and  their  subscribers.  Our  first  installation  in  a  service
provider’s network frequently involves deploying our broadband products in only a portion of the provider’s network and with only a fraction of the capacity
of our products enabled at the time of initial installation. Over time, our customers have generally expanded the use of our solutions to other areas of their
networks  to  increase  network  capacity.  Capacity  expansions  are  accomplished  either  by  deploying  additional  systems,  line  cards,  or  the  sale  of  additional
channels through the use of software. Sales of software-based capacity expansions generate higher gross margins than hardware-based deployments.

Our solutions are commercially deployed in over 70 countries by more than 475 customers, including regional service providers as well as some of the
world’s  largest  Tier  1  broadband  service  providers,  serving  millions  of  subscribers.  Our  principal  customers  include  Charter/Time  Warner  Cable,  Rogers,
Sprint  and  Mediacom  in  North  America;  Televisa/IZZI  Mexico,  Megacable  Mexico  and  Claro  Colombia  in  Latin  America;  Liberty  Global,  Vodafone  and
DNA Oyj in Europe; and Jupiter Communications, Beijing Gehua CATV Networks and China Mobile in Asia-Pacific.

Our revenue for the years ended December 31, 2018, 2017 and 2016 was $297.1 million, $351.6 million and $316.1 million, respectively. Our net
income for the years ended December 31, 2018, 2017 and 2016 was $73.0 million, $88.5 million and $88.7 million, respectively. As of December 31, 2018,
2017 and 2016, our total assets were $474.6 million, $469.7 million and $583.0 million, respectively.

Industry Background and Broadband Service Provider Challenges

As broadband service providers look to address the rapidly evolving demands of consumers and enterprises, we believe they must address several key

challenges.

4

Rapidly Increasing Bandwidth Demand

Bandwidth demand has grown substantially and is expected to continue to increase. Key drivers of this increased demand include:

•

•

•

•

•

•

more users with more connected devices and applications;

more time spent online by users;

the increased use of bandwidth-intensive streaming media services, such as Amazon Prime Video, Netflix and YouTube; cloud applications,
such as iCloud and Dropbox; and augmented and virtual reality applications;

Internet of Things, or IoT, solutions, as already seen in connected homes, business and industries; connected devices such as Amazon Alexa or
Google Assistant; machine-to-machine connectivity; car connectivity and smart cities;

backhaul requirements of wireless service providers; and

the rise of data consumption by enterprises with strict latency requirements on mission-critical and public safety-related applications.

According to the 2018 Cisco Systems Visual Networking Index report, global IP traffic per month is forecasted to grow from 122 exabytes in 2017 (1
exabyte = 1,000,000,000 GB) to 396 exabytes in 2022, representing a 26% compound annual growth rate in global IP traffic; global IP traffic per capita is
expected to increase from 16GB in 2017 to 50GB in 2023; and the number of connected devices is forecast to be 3.6 times the global population by 2022.

Competition Fueled by Increasing Convergence of Service Offerings

Convergence  is  allowing  consumers  and  enterprises  to  enjoy  increased  choice  among  broadband  service  providers.    So-called  “triple-play”  and
“quadruple-play” service offerings are being provided by cable service providers such as Charter and Comcast and diversified telecommunications companies
such as AT&T and Verizon. Mobile-only network operators such as Sprint and T-Mobile are offering higher bandwidth wireless connectivity and, as a result,
cable and fixed communications service providers are experiencing increased “cord cutting” as subscribers opt for mobile only voice and broadband services.
To respond to increased competition, broadband service providers across all access technologies are facing increasing pressure to maintain high bandwidth
availability, while developing differentiated service offerings with higher levels of performance at lower cost to consumers and enterprises.  

Increasing Network Complexity

Historically, broadband service providers have deployed separate systems within their fixed broadband networks for video and data services and have
operated separate networks for fixed, Wi-Fi and mobile services. This traditional model requires service providers to maintain separate network infrastructure
and  personnel  for  each  service. As  network  capacity  and  coverage  have  increased,  and  the  diversity  of  service  offerings  has  grown,  the  need  for  network
infrastructure convergence with reduced operating and capital expenses is increasing.

Need to Control Operating and Capital Expenditures

Operating  hardware-centric  network  infrastructure  is  costly,  with  material  space,  power  and  personnel  requirements.    Moreover,  hardware-centric
networks can be expensive to update or replace. Frequent technology shifts and network upgrade requirements are increasing demand for more cost-efficient
and agile network architectures.  

Opportunity to Transform Broadband Networks

Given the challenges they face, broadband service providers are undertaking three key technology initiatives to help build next-generation networks.

5

 
 
 
 
 
 
Densification

Increasing demand for bandwidth and user expectations for ubiquitous and seamless connectivity require, among other things, the addition of more
access points for users to connect to broadband networks, also known as network densification. Consequently, broadband service providers are shifting from
centralized  to  more  distributed  architectures.  Densification  requires  extending  network  connectivity  and  distributing  access  aggregation  solutions  closer  to
end users. For cable operators this entails deploying more access aggregation nodes and reducing the size of service groups per node. For wireless operators,
this will lead to an emphasis on small, versus traditional macro, cells in new network deployments.

Network Convergence

Today service providers use separate networks to deliver both fixed (cable, fiber or copper) and mobile broadband to their subscribers. To meet the
demands of next generation networks, service providers are focused on converging siloed fixed and mobile core networks into a single converged 5G Core.
Our Axyom Software Platform is a single software framework that supports network convergence by implementing common micro-services across different
virtual network functions, or VNFs.

Virtualization

Service providers are rethinking traditional network architectures and moving toward virtualized, disaggregated and automated network architectures.
The  introduction  of  network  virtualization  is  a  fundamental  change  in  the  way  broadband  service  providers  deliver  critical  network  functions.  Software-
enabled  architectures  are  decoupled  from  underlying  server  hardware  for  increased  efficiency,  upgradability,  configuration  flexibility,  service  agility  and
scalability  not  feasible  with  proprietary  hardware-based  solutions.  Once  the  networks  have  been  virtualized,  a  service-based  architecture  that  supports
scalable network slicing will be launched.

Our Solutions

We offer solutions for fixed and wireless networks. Our software-centric, multi-service broadband platform, Axyom, enables ultra-broadband delivery

and convergence.

We engineered our platform from the ground-up to be high performance, flexible and adaptable, and to allow our customers to seamlessly address the
growing  demand  for  bandwidth  and  connectivity  and  competitive  need  for  service  agility.  Axyom  also  enables  our  customers  to  efficiently  manage  their
networks and provide their subscribers with additional services.

Our software-centric broadband platform provides the following key benefits to broadband service providers:

Addition of Critical Bandwidth Capacity

Our  solutions  enable  broadband  service  providers  to  offer  multi-gigabit  speeds  to  meet  the  growing  demand  for  bandwidth.  Our  platform  permits
software-centric expansion of network capacity to enable rapid bandwidth and service provisioning, helping broadband service providers to respond flexibly
to increased customer demands.

Flexibility to Add New and Expand Existing Services

Our platform provides us with the flexibility to adapt to changing industry standards and customer needs. We designed our Axyom software platform
using what we refer to as Network Function Virtualization 2.0, or NFV 2.0, principles, which allow us to provide and control each needed network function
through a distinct segment of software, which can be integrated or combined in a building block-style fashion with the segments of software responsible for
each other network function. This allows us to offer network architectures that can be efficiently tailored to meet each customer’s specific requirements, both
as  they  exist  at  the  time  of  initial  implementation  and  as  they  evolve  over  time.  When  possible,  we  also  seek  to  implement  new  features  and  enhanced
customization  through  the  use  of  FPGAs,  which  can  be  reprogrammed  in  the  field  as  service  needs  evolve.  This  software-centric  approach  enables  our
customers, in turn, to commercialize new features faster than they could with hardware-centric solutions. For example, our solutions enable broadband service
providers to efficiently add new services and features, such as wholesale connectivity services for wireless service providers, enterprise-class connectivity
services and interactive communication services, such as voice over Wi-Fi and video calling.

6

Ability to Upgrade Networks Remotely

Our  programmable  architecture  allows  us  to  deploy  technology  updates  to  our  customers  remotely  without  the  expense,  disruption  or  network
downtime caused by hardware replacements or field visits by personnel, while minimizing network downtime. We can remotely turn on additional features or
capacity in order to scale our solutions to meet the needs of our customers as they look to broaden the use and capabilities of our products.  Similarly, we are
often able to troubleshoot and assist our customers with technical issues through seamless software updates.

Reduced Network Complexity, Operating Costs and Capital Expenditures

Our converged software platform allows broadband service providers to significantly reduce the complexity and costs of their networks by reducing
parallel and otherwise redundant network architecture. The large capacity increases that our solutions enable, and the ability of our solutions to deliver voice,
video and data over a single platform, mean fewer pieces of equipment in the network, and lower energy usage, operating costs and capital expenditures.

Ability to Densify Networks

Our products help broadband service providers deploy more capacity at the network edge, closer to where end users and devices are accessing the
network, thereby increasing available bandwidth and reducing latency to improve quality of service. For example, our solutions allow cable service providers
to take advantage of new technologies and standards such as distributed access architectures, including passive optical networking, or PON, architectures,
allowing  cable  service  providers  to  move  fiber  closer  to  the  network  edge.  Additionally,  our  portfolio  of  indoor  and  outdoor  small  cells,  Apex  Strand
solutions, and outdoor 5G metro-cells enables wireless operators to improve coverage and enhance throughput, while meeting the standards’ requirements for
new 5G network architectures.

Common Platform Capabilities to Address the Needs of Both Fixed and Wireless Networks

Our software-centric, multi-service platform enables a broad range of network services for fixed and wireless networks, allowing for the delivery of
diverse consumer and enterprise applications. Both fixed and wireless networks share a common set of core and access network functions that enable network
services, such as subscriber management, session management, transport security, access aggregation and RF management. Our Axyom software architecture
allows each of these network functions to be provided and controlled by a distinct segment of software, which can be integrated or combined together in a
building block-style fashion with the segments of software responsible for each other network function. This allows us to offer network architectures that can
be efficiently tailored to meet each customer’s specific requirements, both as they exist at the time of initial implementation and as they evolve over time.

Our Competitive Strengths

The following competitive strengths have helped us become a market leader:

Highly Flexible, Software-Centric Architecture

We have designed our product portfolio from the ground-up to be software-centric and modular in nature. Our proprietary software is at the heart of
our  products.    Our  software-centric  architecture  allows  us  to  virtualize  core  network  and  access  functions  allowing  these  functions  to  be  decoupled  from
underlying hardware, which is not feasible with hardware-centric approaches. As a result, our software-centric architecture allows for increased efficiencies,
upgradability,  configuration  flexibility,  service  agility  and  scalability  while  increasing  the  potential  service  life  of  the  underlying  hardware.  Our  software
allows us to leverage the programmability of FPGAs and general-purpose processors in our solutions.

Proven Engineering and Product Development Track Record

We  have  a  proven  history  of  anticipating  network  evolutions  and  developing  solutions  that  enable  next-generation  networks.  Our  forward-looking
design and investment approach, coupled with our proven product development track record, has enabled us to deliver fully featured next-generation solutions
in advance of competitors. For example, we believe we:

•

were first to market (2005) with a software-centric cable solution leveraging the programmability of FPGAs and general-purpose processors;

7

 
•

•

•

•

•

•

•

were first to market (2008) with a commercially deployed, fully qualified DOCSIS 3.0 cable modem termination system, or CMTS;

were first to market (2012) with a commercially deployed converged cable access platform, or CCAP, delivering IP voice, digital video and
data over a single port;

were first to market (2015) with commercially deployed DOCSIS 3.1-compliant solutions supporting speeds of up to 10 gigabits per second;

were first to market (2016) with a commercially deployable remote-PHY solution;

accelerated innovation (2017) with cloud-native design;

transformed fixed networks (2018) with a commercially deployable vBNG and Multiservice Router; and

unlocked small cell potential (2018) with Strand-mounted Pico cell to support MNO and MSO unique densification requirements.

Strong Management and Engineering Team with a Culture of Innovation

We pride ourselves on our culture of innovation, which is driven by our management team of experienced executives and engineers with deep industry
expertise.  As  of  December  31,  2018,  approximately  86%  of  our  employees  were  engineers  or  had  other  technical  backgrounds.  With  our  talented  and
passionate engineering-led organization, we aim to be an industry visionary and are committed to delivering products based on next-generation technology
before  our  competitors  do.  By  providing  customers  with  direct  access  to  our  engineers  for  product  feedback  and  assistance,  we  believe  our  engineering
expertise contributes to an enhanced customer experience.

Customer Focus

We  have  a  passion  to  serve  our  customers  and  the  agility  and  flexibility  to  offer  solutions  to  meet  their  evolving  requirements.  Our  sales,  sales
engineering,  development  and  support  teams  work  directly  with  customers  to  design,  develop  and  implement  new  solutions  and  to  resolve  customer
problems,  even  if  another  provider  is  the  root  cause  of  the  problem.  Our  product  development  roadmap  is  based  on  our  vision  for  the  future  but  heavily
influenced by near-term and mid-term customer requirements. This market insight helps us meet customer demands and achieve faster time to market with
new features.

Diversified and Established Customer Base

Our solutions are commercially deployed in more than 70 countries by more than 475 customers, including regional service providers as well as some
of  the  largest  Tier  1  broadband  service  providers,  serving  millions  of  subscribers.  According  to  S&P  Global  Intelligence,  our  market  share  by  channels
shipped in the CCAP and CMTS market has been: 27% in 2016; 22% in 2017; and 27% in the nine months ended September 30, 2018. Our wireless solutions
have been purchased by several customers, including Tier 1 mobile operators such as Telefonica, Sprint and China Mobile.  In addition, our wireless solutions
are currently in over 27 trials with 24 prospective customers.

Market Opportunity

We  believe  that  the  shift  to  software-centric  ultra-broadband  networks  and  fixed  and  wireless  convergence  presents  us  with  a  compelling  market
opportunity. Because fixed and wireless networks share a common set of core and access network functions, our platform is capable of addressing the needs
of both fixed and wireless networks.

Our  current  CCAP  solution  addresses  the  service  delivery  needs  of  cable  service  providers.  We  believe  there  is  an  opportunity  for  us  to  take  new
market  share  as  fixed  and  wireless  networks  continue  to  converge.  Although  we  currently  generate  the  majority  of  our  revenue  from  the  fixed  broadband
CCAP  market,  we  expect  to  generate  increased  revenue  in  the  future  from  sales  of  both  wireless  and  PON  solutions  to  new  and  existing  customers.  Our
current wireless products consist of small cells, Wi-Fi and related gateways as well as evolved packet core products. Our small cells and related products
enable  wireless  access,  routing  and  traffic  management  functions  to  support  the  delivery  of  a  number  of  services  to  end  users.  Our  evolved  packet  core
products  enable  subscriber  and  session  management,  security  and  data  exchange  between  the  core  wireless  network  and  wireless  subscribers.  Our  PON
solutions enable cable service providers to push fiber closer to the network edge while leveraging their existing network assets and existing industry-standard
protocols.

representing a 38% compound annual growth rate.

According to S&P Global Market Intelligence, the high-growth segments of the broadband service provider PON market that we address are
projected to grow from $0.9 billion in 2017 to $3.9 billion in 2021, representing a 44% compound annual growth rate.

Our small cell-related solutions have already been purchased by several customers, including Tier 1 mobile operators. Our small cell-related solutions,
components  of  our  evolved  packet  mobile  core  application,  our  vBNG  solution  and  our  PON  solutions  are  currently  in  trials  with  numerous  prospective
customers.

Our Growth Strategy

The key elements of our growth strategy are:

Continue to Innovate and Extend Technology Leadership Through R&D Investment

We believe that we offer market-leading broadband infrastructure products today. We intend to continue to enhance our existing products and develop
new products in both our current and adjacent markets. For example, we have invested in and launched distributed access architecture solutions to allow our
cable customers to densify their networks, providing higher bandwidth, which enhances user experience.

Further Penetrate Existing Customers

Our  customers  often  deploy  our  products  in  a  specific  region  or  for  a  specific  application,  which  may  only  account  for  a  portion  of  their  overall
network  infrastructure  needs.  We  plan  to  expand  our  footprint  within  the  networks  of  existing  customers  as  they  realize  the  technological  and  financial
benefits  of  our  solutions.  Our  software-centric  approach,  which  is  embedded  in  our  products  already  deployed  in  our  customers’  networks,  allows  those
customers to expand network capacity to address increasing bandwidth demand and serve additional users through software.

Expand Our Customer Base

We intend to continue to invest in our sales and marketing organization to increase awareness of our products and services and expand our customer
base. We believe our focus on hiring, training and retaining a knowledgeable and technical sales team helps us build better relationships with customers. We
added approximately 20 customers in 2018.

Expand the Breadth of Solutions Sold to Customers

We intend to sell additional products and solutions to our growing installed base of broadband service providers, particularly as they increasingly offer
converged services to their subscribers. We have invested in developing a virtualized platform that allows us to rapidly provide new applications and services
to our customers.

Continue to Leverage Our Core Technology for the Cable Industry into Adjacent Wireless and Fixed Telco Markets

While we initially focused on providing solutions for cable service providers due to our founders’ experience in the cable industry, the commonalities
between  fixed  and  wireless  network  architectures  have  allowed  us  to  expand  our  solutions  into  the  wireless  market  as  cable  service  providers  have
increasingly sought to add wireless capabilities to their service offerings. Our wireless solutions have been purchased by several customers, including Tier 1
mobile  operators  such  as  Sprint  and  China  Mobile,  and  we  are  in  negotiations  with  several  broadband  service  providers  for  the  purchase  of  our  wireless
solutions. In addition, our wireless solutions are currently in over 27 trials with 24 prospective customers.

Invest in Our Platform through Selective Acquisitions

We  may  selectively  pursue  acquisitions  that  enhance  our  existing  platform  capabilities  and  are  consistent  with  our  overall  growth  strategy.  For
example,  on  February  21,  2019,  we  announced  that  we  had  agreed  to  acquire  NetComm  Wireless  Limited  for  cash  consideration  of  approximately  161.0
million Australian dollars, or AUD ($115.3 million United States dollars, or USD, based on an exchange rate of USD $0.716 per AUD $1.00 on February 21,
2019) to diversify our revenues both geographically and by product channel.

Products and Technology

We  offer  physical  and  virtual  network  solutions  that  enable  our  customers  to  provide  fixed  and  wireless  broadband  services  to  consumers  and

enterprises.

Axyom Software Platform

Our  Axyom  software  platform  is  central  to  our  multi-service,  ultra-broadband  delivery  architecture,  integrating  multiple  core  and  access  network
functions. Axyom is 5G-ready and is designed to provide high performance, programmability, scalability and flexibility. We designed Axyom using NFV 2.0
principles, which allow us to provide and control each needed network function through a distinct segment of software, which can be integrated or combined
together  in  a  building  block-style  fashion  with  the  segments  of  software  responsible  for  each  other  network  function.  This  allows  us  to  offer  network
architectures that can be efficiently tailored to meet each customer’s specific requirements, both as they exist at the time of initial implementation and as they
evolve over time. Axyom has predominantly been integrated into our physical products to date and is increasingly being deployed in virtual environments.

Our Axyom software platform performs several critical network services:

•

•

•

Subscriber  Management.  Enables  dynamic  management  of  subscriber  authentication,  provisioning,  policy  enforcement  and  allocation  of
network resources based on specific end-user service requirements to enhance quality of service.

Session Management.  Intelligently  manages  application  layer  data  streams  to  enable  service  creation  and  delivery  and  enhance  quality  of
service.

RF  Management.  Efficiently  manages  RF  signal  generation  (modulation/demodulation)  while  reducing  noise  to  increase  available  RF
spectrum and maximize data throughput over the network link in both fixed and wireless applications.

10

 
 
 
 
•

•

Access Aggregation. Manages and combines high volume data streams, regardless of connection type, including fixed broadband, Wi-Fi, LTE
and 5G.

Security. Enables end-to-end secure connectivity between users, devices and networks without sacrificing performance.

Axyom  can  be  deployed  on  a  centralized  basis  on  one  of  our  hardware  chassis,  over  distributed  network  hardware  or  as  a  virtualized  solution,

allowing operators to place network functions where they choose, whether close to the network edge or at a centralized location or data center.

Delivery Platforms

Depending  on  customer  preference,  network  requirements  and  current  network  configuration,  our  solutions  can  be  deployed  in  a  centralized,
distributed or virtual environment. While centralized deployments allow our customers to deploy all critical CCAP functions in a single location, distributed
and virtual deployments enable our customers to densify the access network by distributing access deeper into the network, away from existing data centers.

Centralized Deployment. Our C100G CCAP combines CMTS functionality that enables IP data transport from data centers to end-users over cable
networks, including voice over IP and edge-quadrature amplitude modulation, or Edge-QAM, functionality to enable video delivery over cable networks in
one integrated chassis. We believe our C100G CCAP solution was the industry’s first fully integrated CCAP and DOCSIS 3.1 solution. Our C100G CCAP is
capable of supporting downstream speeds of 10 gigabits per second. Our C100G CCAP also features high downstream and upstream channel capacity, and
low  space  and  energy  consumption  requirements.  Using  our  C100G  CCAP,  our  customers  whose  networks  are  configured  for  DOCSIS  3.0  can  adopt
DOCSIS  3.1  through  either  a  software  upgrade  or  a  simple  line  card  addition,  while  continuing  to  service  their  end  customers  who  use  DOCSIS  3.0
modems. We are also able to increase capacity for our C100G CCAP through channel expansions, which are delivered via software-enabled increases in the
bandwidth capacity, regardless of whether it is configured for DOCSIS 3.0 or 3.1. We believe that our software-centric approach will enable us to seamlessly
provide our customers with future upgrades as standards evolve. In addition to our C100G CCAP, we also offer our C40G CCAP, that provides per rack unit
performance comparable to that of our C100G CCAP, but in a smaller form factor.

Distributed Deployment. We offer three solutions for distributed deployment:

•

•

•

Remote-PHY  Solution.  Our  R-PHY  solution  for  cable  networks  consists  of  remotely  deployable  hardware  that  primarily  performs  RF
modulation  and  connects  to  a  CCAP  at  the  network  core  to  provide  subscriber  management,  session  management,  access  aggregation  and
security functions. The remotely deployed R-PHY nodes aggregate end-user traffic for delivery back to the central data center. The software at
the  central  data  center  can  run  on  our  C100G  CCAP  chassis  or  in  a  virtual  environment.  Our  R-PHY  solution  allows  broadband  service
providers that have implemented fiber-deep architectures to deploy ultra-fast fiber connections closer to the end user. By retaining software-
driven network control and intelligence functions at the network core and placing physical layer functions remotely in a fiber node, broadband
services providers can densify their networks to increase operational efficiencies and network capacity.

Remote-MAC/PHY Solution (R-MAC/PHY). Our R-MAC/PHY solution for cable networks offers the capabilities of our R-PHY solution while
also moving media access control functions from the network core to remotely deployed R-MAC/PHY nodes, allowing cable service providers
to increase network throughput to serve more customers at higher speed.

Apex Small Cell Solution. Our portfolio of indoor and outdoor Apex small cell solutions consists of remotely deployable access points that
provide cellular connectivity services at the network edge in conjunction with transport security functions to address coverage and capacity
challenges.  Additionally,  our  small  cell  portfolio  includes  our  Apex  Strand  solution  and  our  outdoor  5G  metro-cell.  These  solutions  allow
broadband  service  providers  to  more  cost-effectively  densify  their  networks  while  simultaneously  improving  coverage  and  enhancing
throughput.

In connection with all of our centralized and distributed deployment solutions, we offer a portfolio of PON solutions, enabling service providers to
move fiber closer to the network edge and deliver a broader range of ultra-broadband services more efficiently and at higher speed. In particular, our portfolio
of PON solutions includes end-to-end network elements, including optical line terminals and optical network units, and a DOCSIS Provisioning over Ethernet
system  for  seamless  integration  of  our  PON  solutions  with  existing  DOCSIS  network  protocols.    In  conjunction  with  our  PON  portfolio,  we  have
commercially deployed its vBNG and Multiservice Router (MSR) to support functional disaggregation and edge deployments which help to transform fixed
networks.

11

 
 
 
 
 
Virtual Deployment. Using our NFV 2.0 software architecture, all of the multi-service applications supported across fixed and wireless by our Axyom
software platform can be delivered on a virtualized basis utilizing commodity servers. We are in trials with numerous prospective customers to deliver multi-
service applications virtually.

Multi-Service Applications

Our  Axyom  software  platform  initially  focused  on  supporting  applications  enabling  fixed  broadband  delivery.  We  have  focused  our  recent
development efforts on expanding Axyom’s capabilities to support wireless applications. We refer to multi-service to describe a set of applications that are
able to support requirements for both fixed and wireless networks.

Cable Network Applications

We  believe  our  C100G  CCAP  was  the  first  solution  offering  full  CCAP  functionality,  allowing  the  delivery  of  voice,  video  and  data  on  a  single

platform. Our CCAP enables three key applications over a single cable network:

•

•

•

DOCSIS Core. Provides high-speed delivery of IP data for broadband connectivity services, including voice over IP.

Video Core. Delivers high speed video processing, including for HD and 4K.

Intelligent Routing. Intelligently manages network traffic to optimize service quality.

Wireless Network Applications

Our Axyom software platform also enables a number of applications addressing the evolving needs of fixed-mobile convergence as well as mobile

network operators:

•

•

•

Security Gateway.  Enables  secure  encrypted  access  for  subscribers  roaming  between  trusted  and  untrusted  networks,  while  providing  high
levels of density and performance.

Small Cells, Wi-Fi and Related Wireless Gateways. Enables routing and security functions as well as traffic management to provide secure
connectivity for wireless endpoints and enable broadband services such as LTE over Wi-Fi, including Wi-Fi calling.

Evolved Packet Mobile Core. Enables subscriber management, session management and authentication, security and data exchange between
the core network and subscribers. Moreover, we have designed and built a commercially deployable 5G converged core supporting fixed and
mobile access.

Capacity Expansion Products

Our CCAP’s flexible design allows our customers to rapidly increase service capabilities and tailor our solution to meet their evolving service needs.

Our software platform permits additional capacity and features to be provisioned remotely, as compared to hardware-centric solutions, which require
wholesale hardware replacements. As new standards and services evolve, and broadband networks become increasingly virtualized, we expect we will be able
to deliver additional capabilities as software-only updates.

Our  line  card  expansion  options  allow  our  customers  to  rapidly  add  new  service  interfaces  and  physical  connection  capacity  without  the  need  for
chassis  replacements.  In  addition,  our  expansion  cards  can  cost-effectively  enable  support  for  our  distributed  access  solutions  utilizing  the  same  C100G
CCAP chassis.

Our Customers

Our solutions are commercially deployed by more than 475 customers, including some of the world’s largest Tier 1 broadband service providers:

•

•

in North America: Charter/Time Warner Cable, Rogers, Sprint and Mediacom;

in Latin America: Televisa/IZZI Mexico, Megacable Mexico and Claro Colombia;

12

•

in Europe: Liberty Global, Vodafone and DNA Oyj; and

in Asia-Pacific: Jupiter Communications, Beijing Gehua CATV Networks and China Mobile.

Sales and Marketing

We sell our products and services through our direct sales force and in partnership with our resellers and sales agents. Our sales force is supported by
our  sales  engineering  team,  which  has  deep  technical  expertise  and  the  capability  for  product  presentations,  product  evaluations,  trials  and  customer
care.  Each  sales  team  is  responsible  for  specific  direct  end-customer  accounts  and/or  a  geographic  territory  across  the  following  regions:  North  America,
Latin America, Asia-Pacific and Europe, Middle East and Africa. We intend to expand our sales force and our reseller and sales agent network.

Our  products  typically  have  a  long  sales  cycle,  requiring  detailed  discussions  with  prospective  customers  about  their  network  requirements  and
technology roadmaps. To help us succeed in a market characterized by long sales cycles, we have developed strong customer relationships, which in turn
provide us with insight into how our products will be deployed in our customers’ networks. We involve product engineers in the sales process, enabling them
to build relationships with customers that are valuable both during implementation and in post-sales customer support. These relationships also provide us
with opportunities to leverage our familiarity with our customers’ needs to make additional sales following the initial sale.

We also use resellers to market, sell and support our products and services, and we use sales agents to assist our direct global sales force with certain

customers primarily located in the Latin America and Asia-Pacific regions.

Our  marketing  activities  consist  primarily  of  technology  conferences,  web  marketing,  trade  shows,  seminars  and  events,  public  relations,  analyst
relations,  demand  generation  and  direct  marketing  to  build  our  brand,  increase  customer  awareness,  communicate  our  product  advantages  and  generate
qualified leads for our field sales force and resellers and sales agents.

Competition

The broadband service provider market is highly competitive and subject to rapidly changing technology trends and shifting customer needs.

We  primarily  compete  with  larger  and  more  established  companies  in  the  broadband  service  provider  market,  such  as  Arris,  Cisco,  Ericsson  and

Nokia.

The principal factors upon which we compete are:

•

•

•

•

•

•

•

product capabilities;

performance;

scalability, flexibility and adaptability to new standards;

ability to innovate;

time to market;

customer support; and

total cost of ownership relative to performance and features.

We believe that we compete favorably with respect to these factors. Nevertheless, many of our competitors have substantial competitive advantages,
including greater name recognition, longer operating histories, and substantially greater financial, technical, research and development or other resources than
we do.

Research and Development

Our  research  and  development  efforts  are  focused  on  developing  new  broadband  products  for  the  cable  and  wireless  markets  and  enhancing  our
current products to meet the current and future needs of our customers. We aim to be first to market with deployable products and are willing to invest early in
research and development and take technological risks to meet this goal. We also seek to enhance our technological innovation through our partnerships with
industry standard-setting

13

 
 
 
 
 
 
 
 
 
organizations and groups, such as CableLabs, 3GPP and Wi-Fi Alliance. These efforts position us to be able to advance industry standards while evolving our
solutions to meet such new standards.

As of December 31, 2018, our research and development organization consisted of 430 employees worldwide, including both software and hardware
engineers. Our research and development expense totaled $71.0 million, $60.7 million and $49.2 million for the years ended December 31, 2018, 2017 and
2016, respectively. We plan to continue to devote substantial resources to our research and development activities.

Manufacturing

We contract with multiple U.S.-based manufacturing firms, including Benchmark and Sanmina, to manufacture the hardware for our products using
the  designs,  components  and  standards  that  we  specify.  After  taking  delivery  from  our  contract  manufacturers,  we  conduct  final  assembly  and  quality
assurance  testing  at  our  facilities  in  Lawrence,  Massachusetts  and  Limerick,  Ireland.  We  believe  our  combination  of  local  manufacturing  and  in-house
assembly and quality assurance allows us to maintain consistency and quality in the products we ship to customers. We also believe that this manufacturing
model enables us to respond quickly to technological changes and supports our engineering goal of being first to market with deployable products. We believe
our inventory management enables us to offer shorter times between order and delivery to our customers as compared to our competitors.

We  enter  into  purchase  agreements  with  our  contract  manufacturers,  generally  with  terms  of  one  year  or  more.  There  are  no  minimum  purchase
requirements  under  these  agreements  and  we  purchase  manufactured  goods  on  a  purchase  order  basis.  As  a  result  of  our  use  of  multiple  contract
manufacturers,  we  believe  that  we  are  not  substantially  dependent  on  the  availability  of  any  single  contract  manufacturer.  Our  contract  manufacturers
purchase the materials and components for our products through a variety of major electronics distributors. The materials and components of our solutions are
generally available in adequate quantities from multiple potential suppliers.

Backlog

We do not have any long-term purchase commitments from customers. Customers generally order products on an as-needed basis with short lead and
delivery times on a per-purchase-order basis. We maintain substantial finished goods inventory to ensure that products can generally be shipped shortly after
receipt of an order.

A portion of our customer shipments in any fiscal period relate to orders received in prior fiscal periods. As of December 31, 2018 and 2017, we had
backlog  of  $28.6  million  and  $40.0  million,  respectively. The  decrease  in  backlog  over  that  period  was  due  principally  to  the  timing  of  shipments  of  our
wireless  and  software-centric  broadband  products,  delivery  of  software-based  capacity  expansions  and  the  timing  of  maintenance  and  support  contract
renewals.  Of  the  amount  of  backlog  as  of  December  31,  2018,  we  expect  that  approximately  $28.6  million  will  be  shipped  within  the  following  twelve
months.  However,  because  our  customers  utilize  purchase  orders  containing  non-binding  purchase  commitments  and  customers  may  cancel,  change  or
reschedule orders without penalty at any time prior to shipment, we have no assurance that we will be able to convert our backlog into shipped orders.

Intellectual Property

Our success depends to a significant degree upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a
combination  of  trade  secrets,  patents,  copyrights  and  trademarks,  as  well  as  contractual  protections.  To  date,  we  have  focused  our  efforts  to  protect  our
intellectual property primarily on trade secrets because the cable industry generally relies on non-patentable CableLabs standards and specifications that are
jointly developed by market participants.

14

We limit access to and use of our proprietary software, technology and other confidential information through the use of internal and external controls,
including  nondisclosure  agreements  with  employees,  consultants,  customers  and  vendors  and  other  measures  for  maintaining  trade  secret  protection.  We
generally  license  our  software  to  customers  pursuant  to  agreements  that  impose  restrictions  on  the  customers’  ability  to  use  the  software,  including
prohibitions on reverse engineering and limitations on the use of copies. We also seek to avoid disclosure of our intellectual property by requiring employees
and  consultants  with  access  to  our  proprietary  information  to  execute  nondisclosure  and  assignment  of  intellectual  property  agreements  and  by  restricting
access to our source code.

We also incorporate a number of third-party software programs into our solutions pursuant to license agreements. Our software is not substantially

dependent on any third-party software, although in some cases it utilizes open source code.

Employees

As of December 31, 2018, we employed 743 full-time employees, of which 394 were located in the United States and 349 were located outside the
United States. Our workforce as of December 31, 2018, consisted of 430 employees in engineering and research and development, 142 employees in sales
and  marketing,  70  employees  in  general  and  administrative,  68  employees  in  manufacturing  and  33  employees  in  services  and  support.  None  of  our
employees  are  represented  by  unions.  We  consider  our  relationship  with  our  employees  to  be  good  and  have  not  experienced  significant  interruptions  of
operations due to labor disagreements.

Our Corporate Information

We were incorporated in the State of Delaware on February 28, 2003. Our principal executive offices are located at 100 Old River Road, Andover,

Massachusetts 01810, and our telephone number at that address is (978) 688-6706.

Item 1A. Risk Factors.

Our  business  is  subject  to  numerous  risks.  The  following  important  factors,  among  others,  could  cause  our  actual  results  to  differ  materially  from
those expressed in forward-looking statements made by us or on our behalf in this Annual Report on Form 10-K and other filings with the Securities and
Exchange Commission, or the SEC, press releases, communications with investors, and oral statements. Actual future results may differ materially from those
anticipated in our forward-looking statements. We undertake no obligation to update any forward-looking statements, whether as a result of new information,
future events, or otherwise.

Risks Related to Our Business and Our Industry

If we do not successfully anticipate technological shifts, market needs and opportunities, and develop new products and product enhancements that meet
those technological shifts, needs and opportunities, we may not be able to compete effectively.

The  broadband  service  provider  market,  including  fixed  and  wireless,  is  characterized  by  rapid  technological  shifts  and  increasingly  complex
customer requirements to achieve scalable networks that accommodate rapidly increasing consumer demand for bandwidth. To compete effectively, we must
continue to develop new technologies and products that address emerging technological trends and changing customer needs. The process of developing new
technology  is  complex  and  uncertain,  and  the  development  of  new  offerings  requires  significant  upfront  investment  that  may  not  result  in  material
improvements to existing products or result in marketable new products or costs savings or revenue for an extended period of time, if at all.

We  believe  that  our  culture  of  innovation  is  a  significant  factor  in  our  ability  to  develop  new  products.  If  we  are  not  able  to  attract  and  retain
employees  that  are  able  to  contribute  to  our  culture  of  innovation,  our  ability  to  identify  emerging  technological  trends  and  changing  customer  needs  and
successfully develop new products to address them could be adversely impacted.

The  success  of  new  products  and  enhancements  also  depends  on  many  other  factors,  including  timely  completion  and  introduction,  differentiation
from  products  offered  by  competitors  and  previous  versions  of  our  own  products  and,  ultimately,  market  acceptance  of  these  new  products  and
enhancements.  In  addition,  new  technologies  or  standards  could  render  our  existing  products  obsolete  or  less  attractive  to  customers.  If  we  are  unable  to
successfully  introduce  new  products  and  enhancements,  we  would  not  be  able  to  compete  effectively  and  our  business,  financial  condition,  results  of
operations and prospects could be materially adversely affected.

Our success depends in large part on broadband service providers’ continued deployment of, and investment in, ultra-broadband network capabilities that
make use of our solutions.

A significant portion of our product and solution suite is dedicated to enabling cable service providers to deliver voice, video and data services over
newer  and  faster  ultra-broadband  networks.  As  a  result,  our  success  depends  significantly  on  these  cable  service  providers’  continued  deployment  of,  and
investment in, their networks, which depends on a number of factors outside of our control. These factors include capital constraints, the presence of available
capacity  on  legacy  networks,  perceived  subscriber  demand  for  ultra-broadband  networks,  competitive  conditions  within  the  broadband  service  provider
industry and regulatory issues. If broadband service providers do not continue deploying and investing in their ultra-broadband networks in ways that involve
our solutions, for these or other reasons, our business, financial condition, results of operations and prospects could be materially adversely affected.

We expect certain of our customers will continue to represent a substantial portion of our revenue.

Historically, certain of our customers have accounted for a significant portion of our revenue. For example, sales to Charter Communications, which
purchased  Time  Warner  Cable  in  2016,  accounted  for  27%,  37%,  and  23%  of  our  revenue  for  the  years  ended  December  31,  2018,  2017  and  2016,
respectively; sales to Liberty Global Affiliates accounted for 11%, 11%, and 10% of our revenue for the years ended December 31, 2018, 2017 and 2016,
respectively;  sales  to  Vodafone  Kabel  Deutschland  GmbH  accounted  for  14%  of  our  revenue  for  the  year  ended  December  31,  2018;  and  sales  to  Rogers
accounted for 12% and 19% of our revenue for the years ended December 31, 2018 and 2016. Based on their historical purchasing patterns, we expect that
our large customers will continue to account for a substantial portion of our revenue in future periods. However, our customers generally make purchases
from us on a purchase-order basis rather than pursuant to long-term contracts, and those that do enter long-term contracts typically have the right to terminate
their contracts for convenience. As a result, we generally have no assurances that these large customers will continue to purchase our solutions.

16

We may also see consolidation of our customer base, which could result in loss of customers. In addition, some of our large customers have used, and may in
the future use, the sizes and relative importance of their orders to our business to require that we enter into agreements with more favorable terms than we
would otherwise agree to and obtain price concessions. The loss of a significant customer, a significant delay or reduction in purchases by large customers or
significant price concessions to one or more large customers, could have a material adverse effect on our business, financial condition, results of operations
and prospects.

Timing  of  large  orders  and  seasonality  in  our  revenue  may  cause  our  quarterly  revenue  and  results  of  operations  to  fluctuate  and  possibly  decline
materially from quarter to quarter.

Our customers tend to make large purchases from us when initiating or upgrading services based on our solutions, followed by smaller purchases for
maintenance  and  ongoing  support.  In  addition,  purchases  by  existing  customers  of  capacity  expansions  can  also  involve  large  individual  orders  that  may
represent a significant portion of our revenue for a fiscal quarter, which may also have a significant impact on our quarterly gross margin due to these capacity
expansions generating higher gross margins than our initial hardware-based deployments. As a result of all of these factors, our quarterly revenue and results
of operations, including our gross margin, may be significantly impacted by one or a small number of large individual orders. For example, any cancellation
of orders or any acceleration or delay in anticipated product purchases or the acceptance of shipped products by a large customer could materially affect our
revenue and results of operations in any quarterly period. We may be unable to sustain or increase our revenue from other new or existing customers to offset
the discontinuation of purchases by one of our larger customers. As a result, our quarterly revenue and results of operations are difficult to estimate and may
fluctuate or decline materially from quarter to quarter.

In addition, we believe that there are significant seasonal factors which may cause revenue to be greater for the first and fourth quarters of our fiscal
year as compared to the second and third quarters. We believe that this seasonality results from a number of factors, including the procurement, budgeting and
deployment  cycles  of  many  of  our  customers. These  seasonal  variations  may  cause  our  quarterly  revenue  and  results  of  operations  to  fluctuate  or  decline
materially from quarter to quarter.

Our sales to the broadband service provider market are volatile and our sales cycles can be long and unpredictable. As a result, our sales and revenue are
difficult to predict and may vary substantially from period to period, which may cause our revenue and results of operations to fluctuate and possibly
decline significantly.

Our sales to the broadband service provider market have been characterized by large and sporadic purchases and long sales cycles. Sales activity often
depends upon the stage of completion of expanding network infrastructures, the availability of funding and the extent to which broadband service providers
are affected by regulatory, economic and business conditions in the countries in which they operate.

In addition, the timing of our sales and revenue recognition is difficult to forecast because of the unpredictability of our products’ sales cycles. A sales
cycle  is  the  period  between  initial  contact  with  a  prospective  customer  and  the  sale  of  our  products  to  that  customer.  Customer  orders  often  involve  the
purchase of multiple products. These orders are complex and difficult to obtain because prospective customers generally consider a number of factors over an
extended period of time before committing to purchase the products and solutions we sell. Customers, especially in the case of our large customers, often
view  the  purchase  of  our  products  as  a  significant  and  strategic  decision  and  require  considerable  time  to  evaluate,  test  and  qualify  our  products  prior  to
making a purchase decision and placing an order. The length of time that customers devote to their evaluation, contract negotiation and budgeting processes
varies significantly, but can often exceed 24 months. During the sales cycle, we expend significant time and money on sales and marketing activities and
make investments in evaluation equipment, all of which are included in our sales and marketing expenses and lower our operating margins, particularly if no
sale occurs.

Even  if  a  customer  decides  to  purchase  our  products,  there  are  many  factors  affecting  the  timing  of  our  recognition  of  revenue,  which  makes  our
revenue difficult to forecast. For example, the sale of our products may be subject to acceptance testing or there may be unexpected delays in a customer’s
internal  procurement  processes,  particularly  for  some  of  our  larger  customers,  for  whom  our  products  represent  a  very  small  percentage  of  their  total
procurement activity. These factors may result in our inability to recognize revenue for months or years following a sale. In addition, other factors that are
specific to particular customers can affect the timing of their purchases and the variability of our revenue recognition, including the strategic importance of a
particular project to a customer, budgetary constraints and changes in their personnel. For all of these reasons, it is difficult to predict whether a sale will be
completed,  the  particular  period  in  which  a  sale  will  be  completed  and  the  period  in  which  revenue  from  a  sale  will  be  recognized.  If  our  sales  cycles
lengthen, our revenue could be

17

lower than expected, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

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

Developing our products is expensive, and the investment in product development may involve a long payback cycle or may result in investments in
technologies  or  standards  that  do  not  get  adopted  in  the  timeframe  we  anticipate,  or  at  all.  For  the  years  ended  December  31,  2018,  2017  and  2016,  our
research and development expenses were $71.0 million, or approximately 23.9% of our revenue, $60.7 million, or approximately 17.3% of our revenue, and
$49.2 million, or approximately 15.6% of our revenue, respectively. We expect to continue to invest heavily in software development in order to expand the
capabilities of our broadband and wireless infrastructure solutions, introduce new products and features and build upon our technology leadership, and we
expect  that  our  research  and  development  expenses  will  continue  to  increase  in  absolute  dollars  and  as  a  percentage  of  revenue  from  2018  to  2019.  Our
investments in research and development may not generate positive returns in a timely fashion or at all.

Our converged cable access platform, or CCAP, solutions currently represent a significant majority of our product sales; this concentration may limit our
ability to increase our revenue, and our business would be adversely affected in the event we are unable to sell one or more of our products.

We are heavily dependent upon the sales of our CCAP solutions. In the event we are unable to market and sell these products or any future product
that  represents  a  substantial  amount  of  our  revenue,  our  business,  financial  condition,  results  of  operations  and  prospects  could  be  materially  adversely
affected.

We have invested heavily in developing wireless solutions, and we face risks in seeking to expand our platform into the wireless market.

We  have  invested  heavily  in  developing  wireless  solutions  that  have  yet  to  generate  any  significant  revenue.  We  cannot  guarantee  that  these
investments, or any of our other investments in research and development, will ever generate material revenue or become profitable for us, and the failure of
these investments to generate positive returns may adversely impact our business, financial condition, results of operations and prospects. The wireless market
makes  up  a  substantial  portion  of  our  total  potential  addressable  market.  In  addition,  expanding  our  offerings  into  the  wireless  market  presents  other
significant risks and uncertainties, including potential distraction of management from other business operations that generate more substantial revenue, the
dedication of significant research and development, sales and marketing, and other resources to this new business line at the expense of our other business
operations and other risks that we may not have adequately anticipated.

We believe the broadband service provider industry is in the early stages of a major architectural shift toward the virtualization of networks and the use of
networks with distributed architectures. If the architectural shift does not occur, if it does not occur at the pace we predict, or if the products and services
we have developed are not attractive to our customers after such shift takes place, our revenues could decline.

We believe the broadband service provider industry is in the early stages of transitioning to the virtualization of networks and the use of networks with
distributed architectures. We are developing products and services that we believe will be attractive to our customers and potential customers who make that
shift.  Our  strategy  depends  in  part  on  our  belief  that  the  industry  shift  to  a  software-centric  cloud-based  architecture  and  increasing  densification  will
continue. In our experience, fundamental changes like this often take time to accelerate and the adoption rates of our customers may vary. As our customers
determine  their  future  network  architectures  and  how  to  implement  them,  we  may  encounter  delayed  timing  of  orders,  deferred  purchasing  decisions  and
reduced expenditures. These longer decision cycles and reduced expenditures may negatively impact our revenues, or make it difficult for us to accurately
predict our revenues, either of which could materially adversely affect our business, financial condition, results of operations and prospects. Moreover, it is
possible  that  our  customers  may  reverse  or  fail  to  expand  upon  current  trends  toward  virtualization  and  distributed  architectures,  which  could  result  in
significantly reduced demand for the products that we have developed and currently plan to develop.

We face intense competition, including from larger, well-established companies, and we may lack sufficient financial or other resources to maintain or
improve our competitive position.

The  market  for  broadband  infrastructure  solutions  is  intensely  competitive,  and  we  expect  competition  to  increase  in  the  future  from  established

competitors and new market entrants. This competition could result in increased pricing pressure,

18

reduced  profit  margins,  increased  sales  and  marketing  expenses  and  our  failure  to  increase,  or  the  loss  of,  market  share,  any  of  which  could  materially
adversely affect our business, financial condition, results of operations and prospects.

In  the  broadband  service  provider  market,  we  primarily  compete  with  larger  and  more  established  companies,  such  as  Arris,  Cisco,  Ericsson  and

Nokia.

Many of our existing and potential competitors enjoy substantial competitive advantages, such as:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

greater name recognition and longer operating histories;

larger sales and marketing budgets and resources;

broader distribution and established relationships with customers;

greater access to larger customer bases;

greater customer support resources;

greater manufacturing resources;

the ability to leverage their sales efforts across a broader portfolio of products;

the ability to leverage purchasing power with vendor subcomponents;

the ability to incorporate additional functionality into their existing products;

the ability to bundle offerings with other products and services;

the ability to set more aggressive pricing policies;

the ability to offer greater amounts of equity and more valuable equity as incentives for purchases of their products and services;

lower labor and development costs;

greater resources to fund research and development or otherwise acquire new product offerings;

larger intellectual property portfolios; and

substantially greater financial, technical, research and development or other resources.

Our ability to compete will depend upon our ability to provide a better solution than our competitors at a price that offers superior value. We may be

required to make substantial additional investments in research, development, sales and marketing in order to respond to competition.

We also expect increased competition if our market continues to expand. Conditions in our market could change rapidly and significantly as a result of
technological advancements or other factors. Current or potential competitors may be acquired by third parties that have greater resources available than we
do. Our current or potential competitors might take advantage of the greater resources of the larger organizations resulting from these acquisitions to compete
more vigorously or broadly with us. In addition, continued industry consolidation might adversely affect customers’ perceptions of the viability of smaller and
even  medium-sized  companies,  such  as  us,  and,  consequently,  customers’  willingness  to  purchase  from  us.  Further,  certain  large  customers  may  develop
broadband infrastructure solutions for internal use and/or to broaden their portfolios of internally developed resources, which could allow these customers to
become new competitors in our market.

If we are unable to sell additional products to our existing customers, our revenue growth will be adversely affected and our revenue could decline.

To increase our revenue, we must sell additional products to our existing customers and add new customers. We expect that a substantial portion of
our  future  sales  will  be  follow-on  sales  to  existing  customers.  For  example,  one  of  our  sales  strategies  is  to  target  sales  of  capacity  expansions  and
implementation  of  wireless  solutions  at  our  current  cable  customers  because  they  are  familiar  with  the  operational  and  economic  benefits  of  our
solutions.  However,  our  existing  customers  may  choose  to  use  other  providers  for  their  infrastructure  needs.  If  we  fail  to  sell  additional  products  to  our
existing customers, our business, financial condition, results of operations and prospects could be materially adversely affected.

We may have difficulty attracting new large customers or acquiring new customers due to the high costs of switching broadband equipment.

Broadband  service  providers  typically  need  to  make  substantial  investments  when  deploying  network  infrastructure,  which  can  delay  a  purchasing
decision. Once a broadband service provider has deployed infrastructure for a particular portion of its network, it is often difficult and costly to switch to
another  vendor’s  infrastructure.  Unless  we  are  able  to  demonstrate  that  our  products  offer  significant  performance,  functionality  or  cost  advantages  that
outweigh a customer’s expense of switching from a competitor’s product, it will be difficult for us to generate sales once that competitor’s equipment has
been deployed. Accordingly, if a customer has already deployed a competitor’s product for its broadband infrastructure, it may be difficult for us to sell our
products  to  that  customer.  If  we  fail  to  attract  new  large  customers  or  acquire  new  customers,  our  business,  financial  condition,  results  of  operations  and
prospects could be materially adversely affected.

We are exposed to the credit risk of some of our customers and to credit exposures in the event of turmoil in the credit markets, which could result in
material losses.

Due  to  our  reliance  on  significant  customers,  we  are  dependent  on  the  continued  financial  strength  of  these  customers.  If  one  or  more  of  our
significant  customers  experience  financial  difficulties,  it  could  result  in  uncollectible  accounts  receivable  and  our  loss  of  such  customers  and  anticipated
revenue.

The  majority  of  our  sales  are  on  an  open  credit  basis,  with  typical  payment  terms  of  one  year  or  less.  We  monitor  individual  customer  payment
capability in granting such open credit arrangements, seeking to limit such open credit to amounts we believe our customers can pay and maintain reserves we
believe are adequate to cover exposure for doubtful accounts. However, there can be no assurance that our open credit customers will pay the amounts they
owe  to  us  or  that  the  reserves  we  maintain  will  be  adequate  to  cover  such  credit  exposure.  Our  customers’  failure  to  pay  and/or  our  failure  to  maintain
sufficient reserves could have a material adverse effect on our consolidated financial statements. In addition, in the event that turmoil in the credit markets
makes  it  more  difficult  for  some  customers  to  obtain  financing,  those  customers’  ability  to  pay  could  be  adversely  impacted,  which  in  turn  could  have  a
material adverse impact on our business and operations.

A portion of our sales is also derived through our resellers, which tend to have more limited financial resources than other customers and to present

increased credit risk. Our resellers also typically have the ability to terminate their agreements with us for any reason upon advance written notice.

We  are  exposed  to  fluctuations  in  currency  exchange  rates,  which  could  adversely  affect  our  business,  financial  condition,  results  of  operations  and
prospects.

Our sales agreements are primarily denominated in U.S. dollars. Therefore, a strengthening U.S. dollar could increase the real cost of our products to
our customers outside of the U.S., and alternatively a decrease in the value of the U.S. dollar relative to foreign currencies could increase our product and
operating costs in foreign locations. If we are not able to successfully hedge against the risks associated with the currency fluctuations, our business, financial
condition, results of operations and prospects could be materially adversely affected.

We  generate  a  significant  amount  of  revenue  from  sales  to  customers  outside  of  the  United  States,  and  we  are  therefore  subject  to  a  number  of  risks
associated with international sales and operations.

We have extensive international operations and generate a significant amount of revenue from sales to customers in Asia-Pacific, Europe and Latin
America. Our ability to grow our business and our future success will depend to a significant extent on our ability to continue to expand our operations and
customer base worldwide.

As a result of our international reach, we must hire and train experienced personnel to staff and manage our foreign operations. To the extent that we
experience  difficulties  in  recruiting,  training,  managing  and  retaining  an  international  staff,  and  specifically  staff  related  to  sales  management  and  sales
personnel, we may experience difficulties in sales productivity in foreign markets. We also enter into strategic relationships with resellers and sales agents in
certain international markets where we do not have a local presence. If we are not able to maintain these relationships or to recruit additional companies to
enter  into  reseller  and  sales  agent  relationships,  our  future  success  in  these  international  markets  could  be  limited.  Business  practices  in  the  international
markets that we serve may differ from those in the U.S. and may require us in the future to include terms other than our standard terms in customer contracts.
To  the  extent  that  we  may  enter  into  customer  contracts  in  the  future  that  include  non-standard  terms  related  to  payment,  warranties  or  performance
obligations, our business, financial condition, results of operations and prospects could be materially adversely affected.

20

Our international sales and operations are subject to a number of risks, including the following:

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

greater risk of unexpected changes in regulatory practices, tariffs and tax laws and treaties;

greater difficulty in enforcing contracts and accounts receivable collection and longer collection periods;

increased expenses incurred in establishing and maintaining our international operations;

fluctuations in exchange rates between the U.S. dollar and foreign currencies where we do business;

greater difficulty and costs in recruiting local experienced personnel;

wage inflation in certain growing economies;

general economic and political conditions in these foreign markets;

economic uncertainty around the world as a result of sovereign debt issues;

communication and integration problems resulting from cultural and geographic dispersion;

limitations on our ability to access cash resources in our international operations;

ability to establish necessary business relationships and to comply with local business requirements;

risks associated with trade restrictions and foreign legal requirements, including the importation, certification and localization of our products
required in foreign countries;

the uncertainty of protection for intellectual property rights in some countries;

delays resulting from our need to comply with foreign cybersecurity laws;

greater  risk  of  a  failure  of  our  operations  and  employees  to  comply  with  both  U.S.  and  foreign  laws  and  regulations,  including  antitrust
regulations; the U.S. Foreign Corrupt Practices Act of 1977, as amended, or the FCPA; privacy and data protection laws and regulations and
any trade regulations ensuring fair trade practices; and

heightened  risk  of  unfair  or  corrupt  business  practices  in  certain  geographies  and  of  improper  or  fraudulent  sales  arrangements  that  may
impact financial results and result in restatements of, or irregularities in, financial statements.

These  and  other  factors  could  harm  our  ability  to  gain  future  international  revenue  and,  consequently,  materially  adversely  affect  our  business,
financial condition, results of operations and prospects. Expanding our existing international operations and entering into additional international markets will
require significant management attention and financial commitments. Our failure to successfully manage our international operations and the associated risks
effectively could limit our future growth or materially adversely affect our business, financial condition, results of operations and prospects.

We are subject to anti-corruption laws such as the FCPA.

We  are  subject  to  anti-corruption  laws  such  as  the  FCPA,  which  generally  prohibits  U.S.  companies  and  their  employees  and  intermediaries  from
making  corrupt  payments  to  foreign  officials  for  the  purpose  of  obtaining  or  keeping  business,  securing  an  advantage  or  directing  business  to  another
individual  or  entity,  and  requires  companies  to  maintain  accurate  books  and  records.  Under  the  FCPA,  U.S.  companies  may  be  held  liable  for  the  corrupt
actions  taken  by  directors,  officers,  employees,  agents,  or  other  strategic  or  local  partners  or  representatives.  We  rely  on  non-employee  third-party
representatives  and  other  intermediaries  to  develop  international  sales  opportunities,  and  generally  have  less  direct  control  over  such  third  parties’  actions
taken  on  our  behalf.  If  we  or  our  intermediaries  fail  to  comply  with  the  requirements  of  the  FCPA  or  similar  legislation,  governmental  authorities  in  the
United  States  and  elsewhere  could  seek  to  impose  civil  and/or  criminal  fines  and  penalties,  which  could  have  a  material  adverse  effect  on  our  business,
reputation, results of operations and financial condition. We intend to increase our international sales and business and, as such, the cost of complying with
such laws, and the potential harm from our noncompliance, are likely to increase.

Failure  to  comply  with  anti-corruption  laws,  such  as  the  FCPA  and  the  United  Kingdom  Bribery  Act  2010,  or  the  Bribery  Act,  and  similar  laws
associated  with  our  activities  outside  the  U.S.,  could  subject  us  to  penalties  and  other  adverse  consequences.  Any  violation  of  the  FCPA,  Bribery  Act  or
similar  laws  could  result  in  whistleblower  complaints,  adverse  media  coverage,  investigations,  loss  of  export  privileges,  severe  criminal  or  civil  sanctions
suspension or debarment from U.S. government contracts, all of which could have a material adverse effect on our reputation, business, results of operations
and prospects. In addition, responding to any enforcement action or related investigation may result in a materially significant diversion of management’s
attention and resources and significant defense costs and other professional fees.

21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We are subject to governmental export and import controls and similar restrictions that could impair our ability to compete in international markets or
subject us to liability if we violate them.

Our products may be subject to various export controls and because we incorporate encryption technology into certain of our products, certain of our
products may be exported from various countries only with the required export license or through an export license exception. Furthermore, certain export
control  and  economic  sanctions  laws  prohibit  the  shipment  of  certain  products,  technology,  software  and  services  to  embargoed  countries  and  sanctioned
governments, entities, and persons. If we fail to comply with the applicable export control laws, customs regulations, economic sanctions or other applicable
laws, we could be subject to monetary damages or the imposition of restrictions which could materially adversely affect our business, financial condition,
results of operations and prospects and could also harm our reputation. Further, there could be criminal penalties for knowing or willful violations, including
incarceration for culpable employees and managers. Obtaining the necessary export license or other authorization for a particular sale may be time-consuming
and may result in the delay or loss of sales opportunities. We previously disclosed that we may have inadvertently violated certain technical provisions of the
U.S.  export  control  laws  and  regulations  by  failing  to  inform  customers  of  their  export  control  obligations  and  failing  to  make  certain  submissions  to  the
Commerce Department’s Bureau of Industry and Security, or BIS, in a timely and complete manner. However, we believe that the exports of our products
were all to destinations and end users that would not have required licensing under the U.S. export control and sanctions laws. We voluntarily disclosed the
potential technical violations to BIS, and, on March 27, 2018, we were notified by BIS that it would not be imposing a penalty regarding this matter.

In  addition,  various  countries  regulate  the  import  of  certain  encryption  technology  and  products,  including  through  import  permit  and  license
requirements, and have enacted laws that could limit our ability to distribute our products or could limit our customers’ ability to implement our products in
those  countries.  Any  change  in  export  or  import  regulations,  economic  sanctions  or  related  legislation,  shift  in  the  enforcement  or  scope  of  existing
regulations or change in the countries, governments, persons or technologies targeted by such regulations could result in decreased use of our products by, or
in our decreased ability to export or sell our products to, existing or potential customers with international operations or create delays in the introduction of
our  products  into  international  markets.  Any  decreased  use  of  our  products  or  limitation  on  our  ability  to  export  or  sell  our  products  could  materially
adversely affect our business, financial condition, results of operations and prospects.

Our revenue growth rate in recent periods may not be indicative of our future performance.

Our revenue growth rate has varied over time, and our revenue performance in recent periods may not be indicative of our future performance. Our
revenue grew 16.0% from the year ended December 31, 2015 to the year ended December 31, 2016 and grew 11.2% from the year ended December 31, 2016
to the year ended December 31, 2017. Our revenue then decreased 15.5% from the year ended December 31, 2017 to the year ended December 31, 2018 and
we may not achieve revenue growth in future periods. You should not rely on our revenue for any prior quarterly or annual period as any indication of our
future revenue or revenue growth. If we are unable to maintain consistent revenue or revenue growth, our business, financial condition, results of operations
and prospects could be materially adversely affected.

As the majority of the growth in our revenue and income from operations has occurred since 2013, it is difficult to evaluate our future prospects.

We were founded in 2003 and booked our first revenue in 2006. The majority of the growth in our revenue and income from operations has occurred
since  2013,  and  it  is  difficult  to  evaluate  our  future  prospects,  including  our  ability  to  plan  for  and  manage  future  growth.  We  have  encountered  and  will
continue  to  encounter  risks  and  difficulties  frequently  experienced  by  rapidly  growing  companies  in  constantly  evolving  industries,  including  the  risks
described  in  this  Annual  Report  on  Form  10-K.  If  we  do  not  address  these  risks  successfully,  our  business,  financial  condition,  results  of  operations  and
prospects could be materially adversely affected, and the market price of our common stock could decline.

Our  products  are  necessary  for  the  operation  of  our  customers’  broadband  service  operations.  Product  quality  problems,  warranty  claims,  services
disruptions, or other defects, errors or vulnerabilities in our products or services could harm our reputation and materially adversely affect our business,
financial condition, results of operations and prospects.

We assist our customers in the operation of their broadband service operations. Failures of our products could result in significant interruptions in our
customers’  capabilities  to  maintain  their  networks  and  operations.  Further,  unsatisfactory  performance  could  cause  us  to  lose  revenue  or  market  share,
increase  our  service  costs,  cause  us  to  incur  substantial  costs  in  analyzing,  correcting  or  redesigning  our  products,  cause  us  to  lose  significant  customers,
subject us to liability for damages

22

and  divert  our  resources  from  other  tasks,  any  one  of  which  could  materially  adversely  affect  our  business,  financial  condition,  results  of  operations  and
prospects.

In addition, sophisticated hardware and operating system software and applications that we produce or procure from third parties may contain defects
in design or manufacture, including “bugs” and other problems that could unexpectedly interfere with the operation of our networks, system, or products.
Such defects could result in warranty claims or claims by customers for losses that they sustain or, in some cases, could allow customers to claim damages. In
the past, we have had to replace certain components of products that we had shipped or provide remediation in response to the discovery of defects or bugs
from failures in software protocols.

Limitation  of  liability  provisions  in  our  standard  terms  and  conditions  of  sale,  and  those  of  our  resellers  and  sales  agents,  may  not  be  enforceable
under some circumstances or may not fully or effectively protect us from end-customer claims and related liabilities and costs. In some cases, including with
respect to indemnification obligations under many of our agreements with customers and resellers, our contractual liability may be uncapped. The sale and
support of our products also entail the risk of product liability claims. We maintain insurance to protect against certain types of claims associated with the use
of our products, but our insurance coverage may not adequately cover any such claims. In addition, even claims that ultimately are unsuccessful could result
in expenditures of funds in connection with litigation and divert management’s time and other resources.

Our products must interoperate with operating systems, software applications and hardware, and comply with industry standards, that are developed by
others, and if we are unable to devote the necessary resources for our products to interoperate with such software and hardware and comply with such
standards, we may lose or fail to increase market share and experience a weakening demand for our products.

Generally, our products comprise only a part of and must interoperate with our customers’ existing infrastructure, specifically their networks, servers,
software and operating systems, which may be manufactured by a wide variety of vendors and original equipment manufacturers. Our products must also
comply with industry standards, such as Data Over Cable Service Interface Specification, or DOCSIS, 3.0 and 3.1, which are established by third parties, in
order to interoperate with such servers, storage, software and other networking equipment such that all systems function efficiently together. We may depend
on  other  vendors  to  support  prevailing  industry  standards.  Also,  some  industry  standards  may  not  be  widely  adopted  or  implemented  uniformly,  and
competing standards and other approaches may emerge that may be preferred by our customers.

In addition, when new or updated versions of these industry standards, software systems or applications are introduced, we must sometimes develop
updated versions of our software so that our products will interoperate properly. We may not accomplish these development efforts quickly, cost-effectively or
at all. These development efforts require capital investment and the devotion of engineering resources. If we fail to maintain compatibility with these systems
and  applications,  our  customers  may  not  be  able  to  adequately  utilize  our  products,  and  we  may  lose  or  fail  to  increase  market  share  and  experience  a
weakening  in  demand  for  our  products,  among  other  consequences,  which  could  materially  adversely  affect  our  business,  financial  condition,  results  of
operations and prospects.

Our ability to sell our products is highly dependent on the quality of our support and services offerings, and our failure to offer high-quality support and
services could have a material adverse effect on our business, financial condition, results of operations and prospects.

Once our products are deployed within our customers’ networks, our customers depend on our support organization to resolve any issues relating to
our  products.  Our  provision  of  high-quality  support  is  critical  for  the  successful  marketing  and  sale  of  our  products.  If  we  do  not  assist  our  customers  in
deploying  our  products  effectively,  do  not  succeed  in  helping  our  customers  resolve  post-deployment  issues  quickly  or  do  not  provide  adequate  ongoing
support, it could adversely affect our ability to sell our products to existing customers and could harm our reputation with potential customers. In addition, our
standard  sales  contracts  require  us  to  provide  minimum  service  requirements  to  our  customers  on  an  ongoing  basis  and  our  failure  to  satisfy  these
requirements  could  expose  us  to  claims  under  these  contracts.  Our  failure  to  maintain  high-quality  support  and  services,  including  compliance  with  our
contractual minimum service obligations, could have a material adverse effect on our business, financial condition, results of operations and prospects.

We base our inventory requirements on our forecasts of future sales. If these forecasts are materially inaccurate, we may procure inventory that we may
be unable to use in a timely manner or at all.

We  and  our  contract  manufacturers  procure  components  and  build  our  products  based  on  our  forecasts.  These  forecasts  are  based  on  estimates  of
future demand for our products, which are in turn based on historical trends and analyses from our sales and marketing organizations, adjusted for overall
market conditions. To the extent our forecasts are materially

23

inaccurate or if we otherwise do not need such inventory, we may under- or over-procure inventory, and such inaccuracies in our forecasts could subject us to
contractual damages and otherwise materially adversely affect our business, financial condition, results of operations and prospects.

Because we depend on third-party manufacturers to build our hardware, we are susceptible to manufacturing delays and pricing fluctuations that could
prevent us from delivering customer orders on time, if at all, or on a cost-effective basis, which may result in the loss of sales and customers.

We  depend  on  third-party  contract  manufacturers  to  manufacture  our  product  hardware.  A  significant  portion  of  our  cost  of  revenue  consists  of
payments to these third-party contract manufacturers. Our reliance on these third-party contract manufacturers reduces our control over the manufacturing
process,  quality  assurance,  product  costs  and  product  supply  and  timing,  which  exposes  us  to  risk.  To  the  extent  that  our  products  are  manufactured  at
facilities in foreign countries, we may be subject to additional risks associated with complying with local rules and regulations in those jurisdictions. If we are
unable to manage our relationships with our third-party contract manufacturers effectively, or if these third-party manufacturers suffer delays or disruptions
for any reason, experience increased manufacturing lead times, capacity constraints or quality control problems in their manufacturing operations or fail to
meet  our  future  requirements  for  timely  delivery,  our  ability  to  ship  products  to  our  customers  would  be  severely  impaired,  and  our  business,  financial
condition, results of operations and prospects could be materially adversely affected.

Our contract manufacturers typically fulfill our supply requirements on the basis of individual orders. We do not have long-term contracts with our
third-party  manufacturers  that  guarantee  capacity,  the  continuation  of  particular  pricing  terms  or  the  extension  of  credit  limits.  Accordingly,  they  are  not
obligated to continue to fulfill our supply requirements, which could result in supply shortages, and increases in the prices for manufacturing services on short
notice. We may not be able to develop alternate contract manufacturers in a timely manner, or at all. If we add or change contract manufacturers, or change
any manufacturing plant locations within a contract manufacturer network, we would add additional complexity and risk to our supply chain management.

In  addition,  we  may  be  subject  to  significant  challenges  in  ensuring  that  quality,  processes  and  costs,  among  other  issues,  are  consistent  with  our
expectations and those of our customers. A new contract manufacturer or manufacturing location may not be able to scale its production of our products at the
volumes or quality we require. This could also adversely affect our ability to meet our scheduled product deliveries to our customers, which could damage our
customer relationships and cause the loss of sales to existing or potential customers, late delivery penalties, delayed revenue or an increase in our costs which
could adversely affect our gross margins. This could also result in increased levels of inventory subjecting us to increased excess and obsolete charges that
could have a negative impact on our results of operations.

Because  some  of  the  key  components  in  our  products  come  from  limited  sources  of  supply,  we  are  susceptible  to  supply  shortages  or  supply  changes,
which could disrupt or delay our scheduled product deliveries to our customers and may result in the loss of sales and customers.

Our products rely on key components that our contract manufacturers purchase on our behalf from a limited number of suppliers, including Altera,
Analog Devices, Bell Power, Broadcom, Maxim, Mini-Circuits, Qorvo, TTM Technologies and Xilinx. We do not have guaranteed supply contracts with any
of  our  component  suppliers,  and  our  suppliers  could  delay  shipments  or  cease  manufacturing  such  products  or  selling  them  to  us  at  any  time.  The
development  of  alternate  sources  for  those  components  is  time-consuming,  difficult  and  costly.  If  we  are  unable  to  obtain  a  sufficient  quantity  of  these
components  on  commercially  reasonable  terms  or  in  a  timely  manner,  sales  of  our  products  could  be  delayed  or  halted  entirely  or  we  may  be  required  to
redesign our products. Any of these events could result in lost sales and damage to our customer relationships, which would adversely impact our business,
financial condition, results of operations and prospects. In the event of a shortage or supply interruption from our component suppliers, we may not be able to
develop alternate or second sources in a timely manner, on commercially reasonable terms or at all. In addition, certain of our customer contracts require us to
notify our customers of any discontinuation of the products that we supply to them and to provide support for discontinued products, and lack of supply from
our suppliers could leave us unable to fulfill our customer support obligations. Adverse changes to our relationships with our sole suppliers could result in lost
sales and damage to our customer relationships, which would adversely impact our business, financial condition, results of operations and prospects.

24

We rely on resellers and sales agents to sell our products into certain international markets, and the loss of such resellers and sales agents could delay or
harm our ability to deliver our products to our customers.

We rely upon resellers and sales agents to coordinate sales and distribution of our products in certain international markets. We provide our resellers
and sales agents with specific training and programs to assist them in selling our products, but these steps may not be effective. In addition, our resellers and
sales agents may be unsuccessful in marketing, selling and supporting our products and services. If we are unable to develop and maintain effective sales
incentive programs for our resellers and sales agents, we may not be able to incentivize these resellers and sales agents to sell our products to customers. Any
of our resellers and sales agents could elect to consolidate or enter into a strategic partnership with one of our competitors, which could reduce or eliminate
our future opportunities with that reseller or sales agent. Our agreements with our resellers and sales agents may generally be terminated for any reason by
either party with advance notice. We may be unable to retain these resellers and sales agents or secure additional or replacement resellers and sales agents.
The replacement of one or more of our significant resellers or sales agents requires extensive training, and any new or expanded relationship with a reseller or
sales agent may take several months or more to achieve productivity. Any of these events could materially adversely affect our business, financial condition,
results of operations and prospects.

Our business and operations have experienced rapid growth in recent years, and if we do not appropriately manage any future growth or are unable to
improve our systems and processes, our business, financial condition, results of operations and prospects will be adversely affected.

We  have  experienced  rapid  growth  and  increased  demand  for  our  products  in  recent  years,  which  have  placed  a  strain  on  our  management,
administrative, operational and financial infrastructure. To handle this growth and increase in demand, we have significantly expanded our headcount, from
604 as of December 31, 2016 to 680 as of December 31, 2017 and to 743 as of December 31, 2018, and we expect to continue to increase our headcount. As
we have grown, we have had to manage an increasingly larger and more complex array of internal systems and processes to scale with all aspects of our
business,  including  our  software  development,  contract  manufacturing  and  purchasing,  logistics  and  fulfillment  and  sales,  maintenance  and  support.  Our
success  will  depend  in  part  upon  our  ability  to  manage  our  growth  effectively.  To  do  so,  we  must  continue  to  increase  the  productivity  of  our  existing
employees and continue to hire, train and manage new employees as needed. To manage domestic and international growth of our operations and personnel,
we will need to continue to improve our operational, financial and management controls and our reporting processes and procedures and implement more
extensive  and  integrated  financial  and  business  information  systems.  We  may  not  be  able  to  successfully  implement  these  or  other  improvements  to  our
systems and processes in an efficient or timely manner, and we may discover deficiencies in their capabilities or effectiveness. Our failure to improve our
systems  and  processes,  or  their  failure  to  operate  effectively  and  in  the  intended  manner,  may  result  in  disruption  of  our  current  operations  and  customer
relationships, our inability to manage the growth of our business and our inability to accurately forecast our revenue, expenses and earnings.

If  we  are  unable  to  hire,  retain,  train  and  motivate  qualified  personnel  and  senior  management,  including  in  particular  our  founders,  our  business,
financial condition, results of operations and prospects could be adversely affected.

Our future success depends, in part, on our ability to continue to attract and retain highly skilled personnel, particularly software engineering and sales
personnel. Competition for highly skilled personnel is often intense, particularly in the greater Boston region where we are headquartered, and we may not be
able to attract and retain the highly skilled employees that we need to support our business. Many of the companies with which we compete for experienced
personnel have greater resources than we have to provide more attractive compensation packages and other amenities. Research and development personnel
are aggressively recruited by startup and growth companies, which are especially active in many of the technical areas and geographic regions in which we
conduct product development. In addition, in making employment decisions, particularly in the high-technology industry, job candidates often consider the
value of the stock-based compensation they are to receive in connection with their employment. Declines in the market price of our stock could adversely
affect our ability to attract, motivate or retain key employees. If we are unable to attract or retain qualified personnel, or if there are delays in hiring required
personnel, our business, financial condition, results of operations and prospects could be materially adversely affected.

Also,  to  the  extent  we  hire  personnel  from  competitors,  or  from  certain  customers  or  other  third  parties  whose  employees  we  have  agreed  not  to
solicit,  we  may  be  subject  to  allegations  that  such  personnel  have  been  improperly  solicited,  that  such  personnel  have  divulged  proprietary  or  other
confidential information or that former employers own certain inventions or other work product. Such claims could result in litigation.

Our future performance also depends on the continued services and continuing contributions of our founders and senior management to execute our
business plan and to identify and pursue new opportunities and product innovations. Our employment arrangements with our employees do not require that
they continue to work for us for any specified period, and

25

therefore, they could terminate their employment with us at any time. In particular, the loss of Jerry Guo, our President and Chief Executive Officer, and
Weidong  Chen,  our  Chief  Technology  Officer,  could  have  a  material  adverse  impact  on  our  business.  Further,  the  loss  of  other  members  of  our  senior
management team, sales and marketing team or engineering team, or any difficulty attracting or retaining other highly qualified personnel in the future, could
significantly delay or prevent the achievement of our development and strategic objectives, which could materially adversely affect our business, financial
condition, results of operations and prospects. Except with respect to Mr. Guo, we do not maintain “key person” life insurance on our officers, directors or
key employees.

If we do not effectively expand and train our direct sales force, we may be unable to increase sales to our existing customers or add new customers, and
our business will be adversely affected.

We  depend  on  our  direct  sales  force  to  increase  sales  with  existing  customers  and  to  obtain  new  customers.  As  such,  we  have  invested  and  will
continue to invest substantially in our sales organization. In recent periods, we have been adding personnel to our sales function as we focus on growing our
business, entering new markets and increasing our market share, and we expect to incur significant additional expenses in expanding our sales personnel in
order to achieve revenue growth. There is significant competition for sales personnel with the skills and technical knowledge that we require. Our ability to
achieve  significant  revenue  growth  will  depend,  in  large  part,  on  our  success  in  recruiting,  training,  retaining  and  integrating  sufficient  numbers  of  sales
personnel to support our growth, particularly in international markets. In addition, we have significantly increased the number of personnel in our sales and
marketing  departments  in  recent  periods,  with  headcount  growing  from  114  as  of  December  31,  2016,  to  122  as  of  December  31,  2017  and  to  142  as  of
December 31, 2018. New hires require significant training and may take significant time before they achieve full productivity. Our recent hires and planned
hires may not become productive as quickly as we expect, and we may be unable to hire, retain or integrate into our corporate culture sufficient numbers of
qualified individuals in the markets where we do business or plan to do business. If we are unable to hire, integrate and train a sufficient number of effective
sales personnel, or the sales personnel we hire are not successful in obtaining new customers or increasing sales to our existing customer base, our business,
financial condition, results of operations and prospects could be materially adversely affected.

26

Adverse economic conditions or reduced broadband infrastructure spending may adversely affect our business, financial condition, results of operations
and prospects.

Our business depends on the overall demand for broadband connectivity. Weak domestic or global economic conditions, fear or anticipation of such
conditions or a reduction in broadband infrastructure spending even if economic conditions improve, could materially adversely affect our business, financial
condition, results of operations and prospects in a number of ways, including longer sales cycles, lower prices for our products and services, reduced sales and
lower or no growth. Continued turmoil in the geopolitical environment in many parts of the world may also affect the overall demand for our products and
services. Deterioration in global economic or political conditions could materially adversely affect our business, financial condition, results of operations and
prospects in the future. A prolonged period of economic uncertainty or a downturn may also significantly affect the availability of capital and the terms and
conditions  of  financing  arrangements,  including  the  overall  cost  of  financing  as  well  as  the  financial  health  or  creditworthiness  of  our  customers.
Circumstances may arise in which we need, or desire, to raise additional capital, and such capital may not be available on commercially reasonable terms, or
at all.

Breaches of our cybersecurity systems and measures could degrade our ability to conduct our business operations and deliver products and services to our
customers,  delay  our  ability  to  recognize  revenue,  compromise  the  integrity  of  our  products,  result  in  significant  data  losses  and  the  theft  of  our
intellectual  property,  damage  our  reputation,  expose  us  to  liability  to  third  parties  and  require  us  to  incur  significant  additional  costs  to  maintain  the
security of our networks and data.

We  increasingly  depend  upon  our  IT  systems  to  conduct  virtually  all  of  our  business  operations,  ranging  from  our  internal  operations  and  product
development activities to our marketing and sales efforts and communications with our customers and business partners. Certain persons and entities may
attempt to penetrate our network and systems, or of the systems hosting our website, and may otherwise seek to misappropriate our proprietary or confidential
information  or  cause  interruptions  of  our  service.  Because  the  techniques  used  by  such  persons  and  entities  to  access  or  sabotage  networks  and  systems
change frequently and may not be recognized until launched against a target, we may be unable to anticipate these techniques. We have also outsourced a
number of our business functions to third parties, including our manufacturers and logistics providers, and our business operations also depend, in part, on the
success of these third parties’ own cybersecurity measures. Additionally, we depend upon our employees and independent contractors to appropriately handle
confidential data and deploy our IT resources in a safe and secure fashion that does not expose our network systems to security breaches and the loss of data.
Accordingly, if any of our cybersecurity systems, processes or policies, or those of any of our manufacturers, logistics providers, customers or independent
contractors,  fail  to  protect  against  unauthorized  access,  sophisticated  hacking  or  terrorism  and  the  mishandling,  misuse,  or  misappropriation  of  data  by
employees, contractors or other persons or entities, our ability to conduct our business effectively could be damaged in a number of ways, including:

•

•

•

•

•

sensitive data regarding our business, including intellectual property, personal information and other confidential and proprietary data, could
be stolen;

our  electronic  communications  systems,  including  email  and  other  methods,  could  be  disrupted,  and  our  ability  to  conduct  our  business
operations could be seriously damaged until such systems can be restored;

our ability to process customer orders and electronically deliver products and services could be degraded, and our distribution channels could
be disrupted, resulting in delays in revenue recognition, damage to our relationships with customers and prospective customers and damage to
our reputation;

defects and security vulnerabilities could be introduced into our software, products, network and systems, thereby damaging our reputation
and perceived reliability and security of our products and potentially making the systems of our customers vulnerable to data loss and cyber
incidents; and

personally identifiable data relating to various parties, including end users, employees and business partners could be compromised.

Should any of the above events occur, we could be subject to significant claims for liability from our customers, employees or others and regulatory
investigations  or  actions  from  governmental  agencies.  In  addition,  our  ability  to  protect  our  intellectual  property  rights  could  be  compromised  and  our
reputation and competitive position could be significantly harmed. Any regulatory, contractual or other actions, litigations, investigations, fines, penalties and
liabilities relating to any actual or alleged misuse or misappropriation of personal data or other confidential or proprietary information could be significant in
terms of monetary exposure and reputational impact and necessitate changes to our business operations that may be disruptive to us. Additionally, we could
incur significant costs in order to upgrade our cybersecurity systems, processes, policies and procedures and remediate damages. Consequently, our financial
performance and results of operations could be materially adversely affected.

27

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

Our success depends, in part, on our ability to protect our proprietary technology. We rely on trade secret, patent, copyright and trademark laws and
confidentiality agreements with employees and third parties to protect and enforce our rights to our proprietary technology, all of which offer only limited
protection.

In order to protect our proprietary information, we rely in significant part on confidentiality arrangements with our employees, licensees, independent
contractors, advisers and customers. These arrangements may not be effective to prevent disclosure of confidential information, including trade secrets, and
may not provide an adequate remedy in the event of unauthorized disclosure of confidential information. In addition, if others independently discover our
trade secrets, we would not be able to assert trade secret rights against such parties. Effective trade secret protection may not be available in every country in
which our services are available or where we have employees or independent contractors. The loss or unavailability of trade secret protection could make it
easier for third parties to compete with our products by copying functionality. In addition, any changes in, or unexpected interpretations of, the trade secret
and  employment  laws  in  any  jurisdiction  in  which  we  operate  may  compromise  our  ability  to  enforce  our  intellectual  property  rights.  Costly  and  time-
consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secret protection
could adversely affect our competitive business position.

We  also  rely  on  patents  to  protect  certain  aspects  of  our  proprietary  technology  in  the  United  States. The  process  of  obtaining  patent  protection  is
expensive and time-consuming, and we may not be able to prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner.
We  may  choose  not  to  seek  patent  protection  for  certain  innovations  and  may  choose  not  to  pursue  patent  protection  in  certain  jurisdictions.  Further,  we
cannot guarantee that any of our pending patent applications will result in the issuance of patents or that any patents that do issue from such applications will
have adequate scope to provide us with a competitive advantage. There is no assurance that all potentially relevant prior art relating to our patents and patent
applications has been found. To the extent that additional patents are issued from our patent applications, which is not certain, third parties may challenge
their  validity,  enforceability  or  scope,  which  may  result  in  such  patents  being  narrowed  or  invalidated.  If  third  parties  have  prepared  and  filed  patent
applications in the United States that also claim technology to which we have rights, we may have to participate in interference proceedings in the United
States Patent and Trademark Office to determine priority of invention for patent applications filed before March 16, 2013, or in derivation proceedings to
determine inventorship for patent applications filed after such date. In addition, patents have a limited lifespan. In the United States, the natural expiration of a
patent  is  generally  20  years  after  its  effective  filing  date.  Even  if  patents  covering  our  products  are  obtained  by  us  or  by  our  licensors,  once  such  patents
expire, we may be vulnerable to competition from similar products. Moreover, the rights granted under any issued patents may not provide us with adequate
protection or competitive advantages, and, as with any technology, competitors may be able to develop similar or superior technologies to our own now or in
the future.

Despite  our  efforts,  the  steps  we  have  taken  to  protect  our  proprietary  rights  may  not  be  adequate  to  preclude  misappropriation  of  our  proprietary
information or infringement of our intellectual property rights, and our ability to police such misappropriation or infringement is uncertain, particularly in
countries outside of the United States. Competitors may use our technologies in jurisdictions where we have not obtained or are unable to adequately enforce
intellectual property protection to develop their own products. We are also restricted from asserting our intellectual property rights against certain customers
under our contracts with them.

Detecting and protecting against the unauthorized use of our products, technology and 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,  to  protect  our  trade  secrets  or  to  determine  the
validity and scope of the proprietary rights of others. Such litigation could result in substantial costs and diversion of management resources, either of which
could materially adversely affect our business, financial condition, results of operations and prospects, and there is no guarantee that we would be successful.
Furthermore,  many  of  our  current  and  potential  competitors  have  the  ability  to  dedicate  substantially  greater  resources  to  protecting  their  technology  or
intellectual property rights than we do. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating
our intellectual property, which could result in a substantial loss of our market share. Even if we did succeed in enforcing our intellectual property through
litigation, this may be costly and divert management resources.

Finally, certain of our license agreements with our third-party licensors provide for joint ownership of developments or inventions that we create that
are related to the subject matter of the license. Other agreements to which we are subject, including member agreements with standards bodies and research
and development consortia, may require us to disclose and/or grant licenses to technology that is related to the subject matter of the standards body or the
consortium and included

28

in  our  contributions  to  specifications  established  by  these  bodies.  These  agreements  could  result  in  third  parties  having  ownership  or  license  rights  to
important intellectual property that we otherwise may have elected to maintain exclusive ownership of.

If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our
business may be adversely affected.

We  have  not  applied  for  trademark  registration  for  our  name  and  logo  in  all  geographic  markets.  In  those  markets  where  we  have  applied  for
trademark  registration,  failure  to  secure  those  registrations  could  adversely  affect  our  ability  to  enforce  and  defend  our  trademark  rights  and  result  in
indemnification claims. Our registered or unregistered trademarks or trade names, as well as the registered or unregistered trademarks or trade names used by
our resellers or distributors associated with our products, may be challenged, infringed, circumvented or declared generic or determined to be infringing on
other marks. Any claim of infringement by a third party, even those claims without merit, could cause us to incur substantial costs defending against such
claim, could divert management attention from our business and could require us to cease use of such intellectual property in certain geographic markets.
Over the long term, if we, or our resellers or distributors, are unable to establish name recognition based on our trademarks and trade names, then our business
may be adversely affected.

Assertions by third parties of infringement or other violations by us of their intellectual property rights, or other lawsuits asserted against us, could result
in significant costs and materially adversely affect our business, financial condition, results of operations and prospects.

Patent  and  other  intellectual  property  disputes  are  common  in  the  broadband  infrastructure  industry  and  have  resulted  in  protracted  and  expensive
litigation for many companies. Many companies in the broadband infrastructure industry, including our competitors and other third parties, as well as non-
practicing  entities,  own  large  numbers  of  patents,  copyrights,  trademarks  and  trade  secrets,  which  they  may  use  to  assert  claims  of  patent  infringement,
misappropriation or other violations of intellectual property rights against us. From time to time, they have or may in the future also assert such claims against
our customers whom we typically indemnify against claims that our products infringe, misappropriate or otherwise violate the intellectual property rights of
third parties.

As the number of products and competitors in our market increases and overlaps occur, claims of infringement, misappropriation and other violations
of intellectual property rights may increase. Any claim of infringement, misappropriation or other violations of intellectual property rights by a third party,
even those without merit, could cause us to incur substantial costs defending against the claim, distract our management from our business and require us to
cease use of such intellectual property, which may impact important elements of our business. In addition, some claims for patent infringement may relate to
subcomponents that we purchase from third parties. If these third parties are unable or unwilling to indemnify us for these claims, we could be substantially
harmed.

The patent portfolios of most of our competitors are larger than ours. This disparity may increase the risk that our competitors may sue us for patent
infringement and may limit our ability to counterclaim for patent infringement or settle through patent cross-licenses. In addition, future assertions of patent
rights  by  third  parties,  and  any  resulting  litigation,  may  involve  patent  holding  companies  or  other  adverse  patent  owners  who  have  no  relevant  product
revenue and against whom our own patents may therefore provide little or no deterrence or protection. We cannot guarantee that we are not infringing or
otherwise violating any third-party intellectual property rights.

The third-party asserters of intellectual property claims may be unreasonable in their demands, or may simply refuse to settle, which could lead to
expensive settlement payments, prolonged periods of litigation and related expenses, additional burdens on employees or other resources, distraction from our
business, supply stoppages and lost sales. Moreover, in recent years, individuals and groups that are non-practicing entities, commonly referred to as “patent
trolls,” have purchased patents and other intellectual property assets for the purpose of making claims of infringement in order to extract settlements. In the
past, we have received threatening letters or notices and have been the subject of claims that our solutions and underlying technology infringe or violate the
intellectual  property  rights  of  others.  Responding  to  such  claims,  regardless  of  their  merit,  can  be  time-consuming,  costly  to  defend  in  litigation,  divert
management’s attention and resources, damage our reputation and brand, and cause us to incur significant expenses.

An adverse outcome of a dispute may require us to pay substantial damages including treble damages if we are found to have willfully infringed a
third  party’s  patents;  cease  making,  licensing  or  using  solutions  that  are  alleged  to  infringe  or  misappropriate  the  intellectual  property  of  others;  expend
additional  development  resources  to  attempt  to  redesign  our  products  or  services  or  otherwise  to  develop  non-infringing  technology,  which  may  not  be
successful; enter into potentially

29

unfavorable royalty or license agreements in order to obtain the right to use necessary technologies or intellectual property rights; and indemnify our partners
and other third parties. Any damages or royalty obligations we may become subject to as a result of an adverse outcome, and any third-party indemnity we
may need to provide, could materially adversely affect our business, financial condition, results of operations and prospects. Royalty or licensing agreements,
if required or desirable, may be unavailable on terms acceptable to us, or at all, and may require significant royalty payments and other expenditures. Further,
there is little or no information publicly available concerning market or fair values for license fees, which can lead to overpayment of license or settlement
fees. In addition, some licenses may be non-exclusive, and therefore our competitors may have access to the same technology licensed to us. Suppliers subject
to third-party intellectual property claims also may choose or be forced to discontinue or alter their arrangements with us, with little or no advance notice to
us. Any of these events could materially adversely affect our business, financial condition, results of operations and prospects.

Unavailability, termination or breach of licenses to third-party software and other intellectual property could materially harm our business.

Many of our products and services include software or other intellectual property licensed from third parties, and we otherwise use software and other
intellectual property licensed from third parties in our business. We exercise no control over our third-party licensors, and the failure or unsuitability of their
software or other intellectual property exposes us to risks that we will have little ability to control. For example, a licensor may have difficulties keeping up
with technological changes or may stop supporting the software or other intellectual property that it licenses to us; our licensors may also have the ability to
terminate our licenses if the licensed technology becomes the subject of a claim of intellectual property infringement. Also, it will be necessary in the future
to renew licenses, expand the scope of existing licenses or seek new licenses, relating to various aspects of these products and services or otherwise relating to
our business, which may result in increased license fees. Any new licenses may not be available on acceptable terms, if at all. In addition, a third party may
assert that we or our customers are in breach of the terms of a license, which could, among other things, give such third party the right to terminate a license
or  seek  damages  from  us,  or  both.  The  inability  to  obtain  or  maintain  certain  licenses  or  other  rights  or  to  obtain  or  maintain  such  licenses  or  rights  on
favorable terms, or the need to engage in litigation regarding these matters, could result in delays in releases of products and services and could otherwise
disrupt our business, until equivalent technology can be identified, licensed or developed, if at all, and integrated into our products and services or otherwise
in the conduct of our business. Moreover, the inclusion in our products and services of software or other intellectual property licensed from third parties on a
nonexclusive basis may limit our ability to differentiate our products from those of our competitors. Any of these events could have a material adverse effect
on our business, financial condition, results of operations and prospects.

Our products contain third-party open source software components, and failure to comply with the terms of the underlying open source software licenses
could restrict our ability to sell our products.

Our  products  contain  software  modules  licensed  to  us  by  third-party  authors  under  “open  source”  licenses.  Use  and  distribution  of  open  source
software  may  entail  greater  risks  than  use  of  third-party  commercial  software,  as  open  source  licensors  generally  do  not  provide  warranties  or  other
contractual  protections  regarding  infringement  claims  or  the  quality  of  the  code.  Some  open  source  licenses  contain  requirements  that  we  make  available
source code for modifications or derivative works we create based upon the type of open source software that we use. If we combine our software with open
source software in a certain manner, we could, under certain open source licenses, be required to release portions of the source code of our software to the
public. This would allow our competitors to create similar products with lower development effort and time and ultimately could result in a loss of product
sales for us.

Although we monitor our use of open source software to avoid subjecting our products to undesirable conditions, we do not have a formal open source
policy  in  place  that  gives  our  developers  written  guidance  on  what  open  source  licenses  we  deem  “safe.”  Further,  even  where  we  believe  an  open  source
license  may  have  acceptable  conditions,  the  terms  of  many  open  source  licenses  have  not  been  interpreted  by  U.S.  courts,  and  these  licenses  could  be
construed in a way that could impose unanticipated conditions or restrictions on our ability to commercialize our products. Moreover, we cannot assure you
that our informal processes for controlling our use of open source software in our products will be effective or that our compliance with open source licenses,
including  notice  and  attribution  requirements,  are  adequate.  If  we  are  held  to  have  breached  the  terms  of  an  open  source  software  license,  we  could  be
required  to  seek  licenses  from  third  parties  to  continue  offering  our  products  on  terms  that  are  not  economically  feasible,  to  re-engineer  our  products,  to
discontinue the sale of our products if re-engineering could not be accomplished on a timely or commercially reasonable basis or to make generally available,
in  source  code  form,  our  proprietary  code.  We  also  could  face  infringement  claims.  Any  of  the  foregoing  could  materially  adversely  affect  our  business,
financial condition, results of operations and prospects.

Our failure to adequately protect personal data and to comply with related laws and regulations could result in material liability.

A  wide  variety  of  provincial,  state,  national,  foreign,  and  international  laws  and  regulations  apply  to  the  collection,  use,  retention,  protection,
disclosure,  transfer  (including  across  national  boundaries),  and  other  processing  of  personal  data.  These  data  protection  and  privacy-related  laws  and
regulations are evolving and being tested in courts and may result in ever-increasing regulatory and public scrutiny and escalating levels of enforcement and
sanctions.

Any failure by us to comply with applicable laws and regulations, or to protect such data, could result in enforcement action against us, including
fines,  imprisonment  of  company  officials,  public  censure,  claims  for  damages  by  end  customers  and  other  affected  persons  and  entities,  damage  to  our
reputation  and  loss  of  goodwill,  and  other  forms  of  injunctive  or  operations-limiting  relief,  any  of  which  could  have  a  material  adverse  effect  on  our
operations, financial performance, and business.

Definitions  of  personal  data  and  personal  information,  and  requirements  relating  to  the  same  under  applicable  laws  and  regulations  within  the
European Union, the United States, and elsewhere, change frequently and are subject to new and different interpretations by courts and regulators. Because
the interpretation and application of laws and other obligations relating to privacy and data protection are uncertain, it is possible that existing or future laws,
regulations, and other obligations may be interpreted and applied in a manner that is inconsistent with our data management practices. We may be required to
expend significant resources to modify our products and otherwise adapt to these changes, which we may be unable to do on commercially reasonable terms
or at all, and our ability to develop new products and features could be limited. These developments could harm our business, financial condition and results
of operations. Even if not subject to legal challenge, the perception of privacy concerns, whether or not valid, may harm our reputation and inhibit adoption of
our products by current and prospective customers.

Failure to comply with governmental laws and regulations could materially adversely affect our business, financial condition, results of operations and
prospects.

Our business is subject to regulation by various federal, state, local and foreign governmental agencies, including agencies responsible for monitoring
and enforcing employment and labor laws, workplace safety, product safety, environmental laws, consumer protection laws, anti-bribery laws, import/export
controls, foreign investment, federal securities laws and tax laws and regulations. In certain jurisdictions, these regulatory requirements may be more stringent
than  those  in  the  United  States.  From  time  to  time,  we  may  receive  inquiries  from  such  governmental  agencies  or  we  may  make  voluntary  disclosures
regarding our compliance with applicable governmental regulations or requirements. Noncompliance with applicable government regulations or requirements
could  subject  us  to  sanctions,  mandatory  product  recalls,  enforcement  actions,  disgorgement  of  profits,  fines,  damages,  civil  and  criminal  penalties  or
injunctions. If any governmental sanctions are imposed, or if we do not prevail in any possible civil or criminal litigation, our business, financial condition,
results of operations and prospects could be materially adversely affected. In addition, responding to any action will likely result in a significant diversion of
management’s attention and resources and an increase in professional fees. Enforcement actions and sanctions could materially adversely affect our business,
financial condition, results of operations and prospects.

We may invest in or acquire other businesses, which could require significant management attention, disrupt our business, dilute stockholder value and
adversely affect our business, financial condition, results of operations and prospects.

As  part  of  our  growth  strategy,  we  may  make  investments  in  or  acquire  complementary  companies,  products  or  technologies.  For  example,  on
February 21, 2019, we announced that we had agreed to acquire NetComm Wireless Limited for cash consideration of approximately AUD $161.0 million
(USD $115.3 million, based on an exchange rate of USD $0.716 per AUD $1.00 on February 21, 2019) to diversify our revenues both geographically and by
product channel. We do not have significant experience in making investments in other companies nor have we made a significant number of acquisitions to
date, and as a result, our ability as an organization to evaluate and/or complete investments or acquire and integrate other companies, products or technologies
in a successful manner is unproven. We may not be able to find suitable future investment or acquisition candidates, and we may not be able to complete such
investments  or  acquisitions  on  favorable  terms,  if  at  all.  Our  pending  acquisition  of  NetComm  Wireless  Limited,  once  completed,  may  not  achieve  its
objectives or strengthen our competitive position. If we complete additional investments or acquisitions, we may not ultimately strengthen our competitive
position  or  achieve  our  goals,  and  any  investments  or  acquisitions  we  complete  could  be  viewed  negatively  by  our  customers,  investors  and  securities
analysts.

In addition, current and future investments and acquisitions may result in unforeseen operating difficulties and expenditures. For example, if we are

unsuccessful at integrating any acquisitions or retaining key talent from those

31

acquisitions, or the technologies associated with such acquisitions, into our company, the business, financial condition, results of operations and prospects of
the combined company could be materially adversely affected. Any integration process may require significant time and resources, and we may not be able to
manage the process successfully. We may not successfully evaluate or utilize the acquired technology or personnel or accurately forecast the financial effects
of an acquisition transaction, including accounting charges. We may have to pay cash, incur debt or issue equity securities to pay for any such investment or
acquisition, each of which could adversely affect our financial condition or the market price of our common stock. The sale of equity or issuance of debt to
finance  any  such  acquisitions  could  result  in  dilution  to  our  stockholders.  The  incurrence  of  indebtedness  would  result  in  increased  fixed  obligations  and
could also include covenants or other restrictions that would impede our ability to manage our operations. Moreover, if the investment or acquisition becomes
impaired, we may be required to take an impairment charge, which could adversely affect our financial condition or the market price of our common stock.

Our international operations may give rise to potentially adverse tax consequences.

We  are  expanding  our  international  operations  and  staff  to  better  support  our  growth  into  the  international  markets.  We  generally  conduct  our
international  operations  through  wholly  owned  subsidiaries  and  report  our  taxable  income  in  various  jurisdictions  worldwide  based  upon  our  business
operations in those jurisdictions. Our corporate structure and associated transfer pricing policies contemplate the business flows and future growth into the
international markets, and consider the functions, risks and assets of the various entities involved in the intercompany transactions. The amount of taxes we
pay  in  different  jurisdictions  may  depend  on  the  application  of  the  tax  laws  of  the  various  jurisdictions,  including  the  United  States,  to  our  international
business activities, changes in tax rates, new or revised tax laws or interpretations of existing tax laws and policies and our ability to operate our business in a
manner consistent with our corporate structure and intercompany arrangements. The taxing authorities of the jurisdictions in which we operate may challenge
our  methodologies  for  pricing  intercompany  transactions,  which  are  required  to  be  computed  on  an  arm’s-length  basis  pursuant  to  the  intercompany
arrangements or disagree with our determinations as to the income and expenses attributable to specific jurisdictions. If such a challenge or disagreement
were to occur, and our position was not sustained, we could be required to pay additional taxes, interest and penalties, which could result in one-time tax
charges, higher effective tax rates, reduced cash flows and lower overall profitability of our operations. Our financial statements could fail to reflect adequate
reserves to cover such a contingency.

On December 22, 2017, the President signed into law new U.S. federal income tax legislation that contains significant changes to corporate taxation,
including the transition of U.S. international taxation to a modified territorial system and the imposition of a one-time transition tax on a deemed repatriation
of certain foreign earnings and profits. While we have recorded the impacts of U.S. tax reform based on our interpretation of the provisions as enacted, it is
expected  the  U.S.  Department  of  Treasury,  the  IRS  and  state  tax  authorities  will  issue  additional  interpretative  guidance  in  the  future  that  could  result  in
changes to previously finalized provisions. The overall impact of this new legislation is uncertain, and our business and financial condition could be adversely
affected. In addition, further changes in the tax laws of foreign jurisdictions could arise, including as a result of the base erosion and profit shifting project
undertaken by the Organisation for Economic Co-operation and Development, or the OECD. The OECD, which represents a coalition of member countries,
has issued recommendations that, in some cases, make substantial changes to numerous long-standing tax positions and principles; many of these changes
have been adopted or are under active consideration by OECD members and/or other countries.

Recent changes to the U.S. tax laws impact the tax treatment of foreign earnings by, among other things, creating limits on the ability of taxpayers to
claim and utilize foreign tax credits, imposing minimum effective rates of current tax on certain classes of foreign income, and imposing additional taxes in
connection with specified payments to related foreign recipients. While some of the changes made in the 2017 U.S. tax reform may be adverse on a going
forward basis, the Company intends to work with its tax advisors to determine the full impact of tax reform and to utilize the potential benefits that may be
applicable to the Company.    Due  to  our  existing,  and  anticipated  expansion  of,  our  international  business  activities,  any  additional  guidance  such  as  U.S
Treasury  regulations  and  administrative  interpretations  may  increase  our  worldwide  effective  tax  rate  and  adversely  affect  our  financial  condition  and
operating results.

Taxing authorities may successfully assert that we should have collected or in the future should collect sales and use, value added or similar taxes, and we
could be subject to liability with respect to past or future sales, which could adversely affect our operating results.

We do not collect sales and use, value added or similar taxes in all jurisdictions in which we have sales, and we have been advised that such taxes are
not applicable to our products and services in certain jurisdictions. Sales and use, value added and similar tax laws and rates vary greatly by jurisdiction.
Certain jurisdictions in which we do not collect such taxes may assert that such taxes are applicable, which could result in tax assessments, penalties and
interest, to us or our end-customers for the past amounts, and we may be required to collect such taxes in the future. If we are unsuccessful in

32

collecting such taxes from our end-customers, we could be held liable for such costs. Such tax assessments, penalties and interest, or future requirements may
adversely affect our operating results.

If we needed to raise additional capital to expand our operations and invest in new products, our failure to do so on favorable terms could reduce our
ability to compete and could materially adversely affect our business, financial condition, results of operations and prospects.

We expect that our existing cash and cash equivalents will be sufficient to meet our anticipated cash needs for at least the next 12 months. However, if
we need to raise additional funds to expand our operations and invest in new products, we may not be able to obtain additional debt or equity financing on
favorable terms, if at all. If we raise additional equity financing, our stockholders may experience significant dilution of their ownership interests, and the
market price of our common stock could decline.

Our  business  is  subject  to  the  risks  of  fire,  power  outages,  floods  and  other  catastrophic  events  and  to  interruption  by  manmade  problems  such  as
terrorism.

Our corporate headquarters and the operations of our key manufacturing vendors, as well as many of our customers, are located in areas exposed to
risks of natural disasters such as fires and floods. A significant natural disaster, such as a fire, flood or other catastrophic events such as a disease outbreak,
could  have  a  material  adverse  effect  on  our  or  their  business,  which  could  in  turn  materially  adversely  affect  our  business,  financial  condition,  results  of
operations  and  prospects.  For  example,  in  the  event  our  manufacturing  or  logistics  abilities  are  hindered  by  any  of  the  events  discussed  above,  shipments
could be delayed, which could result in missed financial targets, such as revenue and shipment targets, for a particular quarter. Further, if a natural disaster
occurs in a region from which we derive a significant portion of our revenue, customers in that region may delay or forego purchases of our products, which
could materially adversely affect our business, financial condition, results of operations and prospects. In addition, acts of terrorism could cause disruptions in
our business or the business of our manufacturers, logistics providers, partners or customers or the economy as a whole. All of the aforementioned risks may
be compounded if our disaster recovery plans and those of our manufacturers, logistics providers or partners prove to be inadequate. To the extent that any of
the above results in delays or cancellations of customer orders, or delays in the manufacture, deployment or shipment of our products, our business, financial
condition, results of operations and prospects would be adversely affected.

Regulations affecting broadband infrastructure could reduce demand for our products.

Laws and regulations governing the Internet and electronic commerce are emerging but remain largely unsettled, even in the areas where there has
been some legislative action. Regulations may focus on, among other things, assessing access or settlement charges, or imposing tariffs or regulations based
on  the  characteristics  and  quality  of  products,  either  of  which  could  restrict  our  business  or  increase  our  cost  of  doing  business.  Government  regulatory
policies are likely to continue to have a major impact on the pricing of existing and new network services and, therefore, are expected to affect demand for
those services and the communications products, including our products, supporting those services.

Any changes to existing laws or the adoption of new regulations by federal or state regulatory authorities or any legal challenges to existing laws or
regulations affecting IP networks could materially adversely affect the market for our products. Moreover, customers may require us, or we may otherwise
deem it necessary or advisable, to alter our products to address actual or anticipated changes in the regulatory environment. Our inability to alter our products
or address any regulatory changes could have a material adverse effect on our consolidated financial position, results of operations or cash flows.

We  have  outstanding  debt  that  could  limit  our  ability  to  make  expenditures  and  investments  in  the  conduct  of  our  business  and  adversely  impact  our
ability to obtain future financing.

We have outstanding debt. We may be unable to generate cash sufficient to pay when due the principal of, interest on or other amounts due in respect
of our indebtedness. We may be required to dedicate significant cash flows from operations to make such payments, which could limit our ability to make
other expenditures and investments in the conduct of our business. Our indebtedness may also reduce our flexibility in planning for or reacting to changes in
our business and market conditions. Our indebtedness also exposes us to interest rate risk, since our debt obligations generally bear interest at variable rates.
In addition, we may incur additional indebtedness in the future to meet future financing needs. If we add new debt, the risks described above could increase.

33

The elimination of LIBOR could adversely affect our business, results of operations or financial condition.

In  July  2017,  the  head  of  the  United  Kingdom  Financial  Conduct  Authority  announced  plans  to  phase  out  the  use  of  LIBOR  by  the  end  of  2021.
Although  the  impact  is  uncertain  at  this  time,  the  elimination  of  LIBOR  could  have  an  adverse  impact  on  our  business,  results  of  operations,  or  financial
condition.    We  may  incur  significant  expenses  to  amend  our  LIBOR-indexed  loans,  derivatives,  and  other  applicable  financial  or  contractual  obligations,
including our credit facilities, to a new reference rate, which may differ significantly from LIBOR.  Accordingly, the use of an alternative rate could result in
increased  costs,  including  increased  interest  expense  on  our  credit  facilities,  and  increased  borrowing  and  hedging  costs  in  the  future.  Additionally,  the
elimination of LIBOR may adversely impact the value of and the expected return on our existing derivatives. At this time, no consensus exists as to what rate
or rates may become acceptable alternatives to LIBOR and we are unable to predict the effect of any such alternatives on our business, results of operations or
financial condition.

Our credit facility contains restrictive and financial covenants that may limit our operating flexibility.

Our  credit  facility  contains  certain  restrictive  covenants  that  either  limit  our  ability  to,  or  require  a  mandatory  prepayment  in  the  event  we,  incur
additional indebtedness and liens, merge with other companies or consummate certain changes of control, acquire other companies, engage in new lines of
business,  change  business  locations,  make  certain  investments,  make  any  payments  on  any  subordinated  debt,  transfer  or  dispose  of  assets,  amend  certain
material agreements, and enter into various specified transactions. We, therefore, may not be able to engage in any of the foregoing transactions unless we
obtain the consent of our lender or prepay the outstanding amount under the credit facility. The credit facility also contains certain financial covenants and
financial reporting requirements. Our obligations under the credit facility are secured by substantially all of our assets, excluding intellectual property and
investments in foreign subsidiaries. We may not be able to generate or sustain sufficient cash flow or sales to meet the financial covenants or pay the principal
and interest under the credit facility. Furthermore, our future working capital, borrowings or equity financing could be unavailable to repay or refinance the
amounts  outstanding  under  the  credit  facility.  In  the  event  of  a  liquidation,  our  lender  would  be  repaid  all  outstanding  principal  and  interest  prior  to
distribution  of  assets  to  unsecured  creditors,  and  the  holders  of  our  common  stock  would  receive  a  portion  of  any  liquidation  proceeds  only  if  all  of  our
creditors, including our lender, were first repaid in full.

Risks Related to Our Common Stock

Our  results  of  operations  are  likely  to  vary  significantly  from  period  to  period  and  be  unpredictable.  If  we  fail  to  meet  the  expectations  of  analysts  or
investors, the market price of our common stock could decline substantially.

Our results of operations have historically varied from period to period, and we expect that this trend will continue. As a result, you should not rely
upon our past financial results for any period as indicators of future performance. Our results of operations in any given period can be influenced by a number
of factors, many of which are outside of our control and may be difficult to predict, including the factors described above as well as:

•

•

•

•

•

•

•

•

•

changes in our pricing policies, whether initiated by us or as a result of competition;

the amount and timing of operating costs and capital expenditures related to the operation and expansion of our business;

changes in the growth rate of the broadband services market;

the  actual  or  rumored  timing  and  success  of  new  product  and  service  introductions  by  us  or  our  competitors  or  any  other  change  in  the
competitive landscape of our industry, including consolidation among our competitors or customers;

our ability to successfully expand our business geographically;

insolvency or credit difficulties confronting our customers, which could adversely affect their ability to purchase or pay for our products and
services, or confronting our key suppliers, including our sole source suppliers, which could disrupt our supply chain;

our inability to fulfill our customers’ orders due to supply chain delays, access to key commodities or technologies or events that impact our
manufacturers or their suppliers;

the cost and possible outcomes of any potential litigation matters;

our overall effective tax rate, including impacts caused by any changes in the valuation of our deferred tax assets and any new legislation or
regulatory developments;

34

 
 
 
 
 
 
 
 
 
•

•

increases or decreases in our expenses caused by fluctuations in foreign currency exchange rates; and

general economic conditions, both domestically and in foreign markets.

Any one of the factors above or the cumulative effect of several of the factors described above may result in significant fluctuations in our financial
and other results of operations. This variability and unpredictability could result in our failure to meet expectations of securities analysts or investors for a
particular  period.  If  we  fail  to  meet  or  exceed  such  expectations  for  these  or  any  other  reasons,  the  market  price  of  our  common  stock  could  decline
substantially, and we could face costly lawsuits, including securities class action suits.

An active trading market for our common stock may not be sustained.

Our  common  stock  began  trading  on  the  Nasdaq  Global  Select  Market  on  December  15,  2017.    Given  the  limited  trading  history  of  our  common
stock,  there  is  a  risk  that  an  active  trading  market  for  our  shares  may  not  be  sustained,  which  could  put  downward  pressure  on  the  market  price  of  our
common stock and thereby affect the ability of our stockholders to sell their shares at attractive prices, at the times that they would like to sell them, or at all.

The market price of our common stock may be volatile, which could result in substantial losses for investors.

The  market  price  of  our  common  stock  could  be  subject  to  significant  fluctuations.  Some  of  the  factors  that  may  cause  the  market  price  of  our

common stock to fluctuate include:

•

•

•

•

•

•

•

•

•

•

•

actual or anticipated changes in our earnings or fluctuations in our results of operations or in the expectations of securities analysts;

price and volume fluctuations in the overall stock market from time to time;

volatility in the market price and trading volume of comparable companies;

announcements of technological innovations, new products, strategic alliances, or significant agreements by us or by competitive vendors;

announcements by our customers regarding significant increases or decreases in capital expenditures;

departure of key personnel;

litigation involving us or that may be perceived as having an impact on our business;

changes in general economic, industry and market conditions and trends;

investors’ general perception of us;

sales of large blocks of our stock; and

announcements regarding further industry consolidation.

In  the  past,  following  periods  of  volatility  in  the  market  price  of  a  company’s  securities,  securities  class  action  litigation  has  often  been  brought
against that company. Because of the potential volatility of our stock price, we may become the target of securities litigation in the future. Securities litigation
could result in substantial costs and divert management’s attention and resources from our business.

We have broad discretion in the use of our cash reserves and may not use them effectively.

Subject to restrictions in the agreements governing our indebtedness, our management has broad discretion to use our cash reserves and could use our
cash reserves in ways that do not improve our results of operations or enhance the value of our common stock.  The failure by our management to apply these
funds effectively could adversely affect our ability to operate and grow our business.  Pending their use, we may invest our cash reserves in a manner that
does not produce income or that loses value.

35

 
 
 
 
 
 
 
 
 
 
 
 
 
If securities or industry analysts cease publishing research or reports about us, our business or our market, or if they publish negative evaluations of our
stock or the stock of other companies in our industry, the price of our stock and trading volume could decline.

The trading market for our common stock will be influenced by the research and reports that industry or securities analysts may publish about us, our
business, our market or our competitors. If one or more of the industry analysts covering our business downgrade their evaluations of our stock or the stock of
other companies in our industry, the price of our stock could decline. If one or more of these analysts cease to cover our stock, we could lose visibility in the
market for our stock, which in turn could cause our stock price to decline.

Because we do not expect to declare any dividends on our common stock for the foreseeable future, investors in our common stock may never receive a
return on their investment.

Although  we  declared  special  dividends  on  five  occasions  prior  to  our  initial  public  offering,  we  do  not  anticipate  that  we  will  declare  any  cash
dividends to holders of our common stock in the foreseeable future, and investors should not rely on an investment in our common stock to provide dividend
income. Instead, we plan to retain any earnings to maintain and expand our existing operations. Accordingly, investors must rely on sales of their common
stock after price appreciation, which may never occur, as the only way to realize any return on their investment. As a result, investors seeking cash dividends
should not purchase our common stock.

Any  future  determination  to  declare  dividends  will  be  made  at  the  discretion  of  our  board  of  directors  and  will  depend  on  a  number  of  factors,
including future earnings, capital requirements, financial conditions, future prospects, contractual restrictions and covenants and other factors that our board
of directors may deem relevant. Our credit facility contains covenants that limit our ability to pay dividends on our capital stock.

Insiders have substantial control over us, which could limit your ability to influence the outcome of key transactions, including a change of control.

As  of  January  31,  2019,  our  directors,  executive  officers  and  10%  stockholders  beneficially  owned,  in  the  aggregate,  approximately  64.5%  of  our
outstanding common stock. As a result, these stockholders could have significant influence over the outcome of matters submitted to our stockholders for
approval, including the election of directors and any merger, consolidation or sale of all or substantially all of our assets, and over the management and affairs
of our company. This concentration of ownership may have the effect of delaying or preventing a change in control of our company and might affect the
market price of our common stock.

A significant portion of our total outstanding shares may be sold into the public market in the near future, which could cause the market price of our
common stock to drop significantly, even if our business is doing well.

Sales of a significant number of shares of our common stock in the public market could occur at any time. These sales, or the market perception that

the holders of a large number of shares intend to sell shares, could reduce the market price of our common stock.

In  addition  to  our  outstanding  common  stock,  as  of  January  31,  2019,  there  were  9,545,780  shares  subject  to  outstanding  options,  525,511  shares
subject  to  outstanding  restricted  stock  unit  awards,  or  RSUs,  and  an  additional  11,765,262  shares  reserved  for  future  issuance  under  our  equity  incentive
plans. Because we have registered most shares of common stock that may be issued under our equity incentive plans pursuant to a Registration Statement on
Form S-8, any such registered shares that we issue can be freely sold in the public market upon issuance, subject to the restrictions imposed on our affiliates
under Rule 144.

Moreover, holders of an aggregate of approximately 37,129,787 shares of our common stock as of January 31, 2019, have rights, subject to certain
conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves
or other stockholders. Upon registration, such shares would be able to be freely sold in the public market.

36

Anti-takeover provisions in our restated certificate of incorporation and our amended and restated bylaws, as well as provisions of Delaware law, might
discourage, delay or prevent a change in control of our company or changes in our management and, therefore, depress the trading price of our common
stock.

Our restated certificate of incorporation and amended and restated bylaws and Delaware law contain provisions that may discourage, delay or prevent
a  merger,  acquisition  or  other  change  in  control  that  stockholders  may  consider  favorable,  including  transactions  in  which  you  might  otherwise  receive  a
premium  for  your  shares  of  our  common  stock.  These  provisions  may  also  prevent  or  delay  attempts  by  our  stockholders  to  replace  or  remove  our
management. Our corporate governance documents include provisions:

•

•

•

•

•

•

establishing a classified board of directors with staggered three-year terms so that not all members of our board are elected at one time;

providing that directors may be removed by stockholders only for cause and only with a vote of the holders of at least 75% of the issued and
outstanding shares of common stock;

limiting the ability of our stockholders to call and bring business before special meetings and to take action by written consent in lieu of a
meeting;

requiring  advance  notice  of  stockholder  proposals  for  business  to  be  conducted  at  meetings  of  our  stockholders  and  for  nominations  of
candidates for election to our board of directors;

authorizing blank check preferred stock, which could be issued with voting, liquidation, dividend and other rights superior to our common
stock; and

limiting the liability of, and providing indemnification to, our directors and officers.

As  a  Delaware  corporation,  we  are  also  subject  to  provisions  of  Delaware  law,  including  Section  203  of  the  Delaware  General  Corporation  Law,
which limits the ability of stockholders holding more than 15% of our outstanding common stock from engaging in certain business combinations with us.
Any  provision  of  our  restated  certificate  of  incorporation  or  amended  and  restated  bylaws  or  Delaware  law  that  has  the  effect  of  delaying  or  deterring  a
change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock, and could also affect the price
that some investors are willing to pay for our common stock.

The  existence  of  the  foregoing  provisions  and  anti-takeover  measures  could  limit  the  price  that  investors  might  be  willing  to  pay  in  the  future  for
shares of our common stock. They could also deter potential acquirers of our company, thereby reducing the likelihood that you could receive a premium for
your common stock in an acquisition.

Our restated certificate of incorporation provides that the Court of Chancery of the State of Delaware will be the exclusive forum for substantially all
disputes between us and our stockholders. Our restated certificate of incorporation further provides that the federal district courts of the United States are
the  sole  and  exclusive  forum  for  the  resolution  of  any  complaint  asserting  a  cause  of  action  arising  under  the  Securities  Act.  These  choice  of  forum
provisions could limit our stockholders’ ability to obtain a more favorable judicial forum for disputes with us or our directors, officers or employees.

Our restated certificate of incorporation provides that the Court of Chancery of the State of Delaware is the exclusive forum for any derivative action
or proceeding brought on our behalf; any action asserting a breach of fiduciary duty; any action asserting a claim against us arising pursuant to the Delaware
General Corporation Law, our certificate of incorporation or our bylaws; or any action asserting a claim against us that is governed by the internal affairs
doctrine.  Our  restated  certificate  of  incorporation  further  provides  that,  unless  we  consent  in  writing  to  the  selection  of  an  alternative  forum,  the  federal
district courts of the United States shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a
cause  of  action  arising  under  the  Securities  Act  of  1933,  as  amended,  or  the  Securities  Act.  On  December  19,  2018,  the  Delaware  Court  of  Chancery,  in
Sciabacucchi  v.  Salzberg,  et  al.,  C.A.  No.  2017-0931-JTL  (Del.  Ch.  Dec.  19,  2018),  held  that  such  federal  forum  selection  provisions  are  invalid  under
Delaware law. These choice of forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with
us or our directors, officers or other employees, which may discourage such lawsuits against us and our directors, officers and other employees. Alternatively,
if a court were to find the choice of forum provisions contained in our certificate of incorporation to be inapplicable or unenforceable in an action, we may
incur additional costs associated with resolving such action in other jurisdictions, which could materially adversely affect our business, financial condition,
results of operations and prospects.

We are an “emerging growth company,” and the reduced disclosure requirements applicable to emerging growth companies may make our common stock
less attractive to investors.

We  are  an  “emerging  growth  company,”  as  defined  in  the  Jumpstart  Our  Business  Startups  Act  of  2012,  or  the  JOBS  Act,  and  may  remain  an
emerging growth company until the last day of our fiscal year following the fifth anniversary of our initial public offering, subject to specified conditions. For
so  long  as  we  remain  an  emerging  growth  company,  we  are  permitted,  and  intend,  to  rely  on  exemptions  from  certain  disclosure  requirements  that  are
applicable  to  other  public  companies  that  are  not  emerging  growth  companies.  These  exemptions  include  being  permitted  to  provide  reduced  disclosure
regarding  executive  compensation  and  exemptions  from  the  requirements  to  hold  non-binding  advisory  votes  on  executive  compensation  and  golden
parachute payments, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002 related to our
internal control over financial reporting, and not being required to comply with any requirement that may be adopted by the Public Company Accounting
Oversight  Board  regarding  a  supplement  to  the  auditor’s  report  providing  additional  information  about  the  audit  and  the  financial  statements.  We  cannot
predict whether investors will find our common stock less attractive if we rely on these exemptions. If some investors find our common stock less attractive
as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.

Further,  Section  102(b)(1)  of  the  JOBS  Act  exempts  emerging  growth  companies  from  being  required  to  comply  with  new  or  revised  financial
accounting standards until private companies (that is, companies that have not filed a pending registration statement under the Securities Act, had a Securities
Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended, or the
Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of
the  extended  transition  period  and  comply  with  the  requirements  that  apply  to  non-emerging  growth  companies,  but  any  such  an  election  to  opt  out  is
irrevocable. We have elected not to opt out of such extended transition period, which means that when a standard is issued or revised, and it has different
application dates for public or private companies, we will adopt the new or revised standard at the time private companies adopt the new or revised standard,
provided that we continue to be an emerging growth company. This may make comparison of our financial statements with the financial statements of another
public company that is not an emerging growth company, or an emerging growth company that has opted out of using the extended transition period, difficult
or impossible because of the potential differences in accounting standards used.

We will remain an emerging growth company until the last day of the fiscal year following the fifth anniversary of our initial public offering or such
earlier time that we are no longer an emerging growth company. We would cease to be an emerging growth company if we have more than $1.07 billion in
annual revenue, we have more than $700 million in market value of our stock held by non-affiliates (and we have been a public company for at least 12
months and have filed one Annual Report on Form 10-K) or we issue more than $1 billion of non-convertible debt securities over a three-year period.

We are subject to new U.S. foreign investment regulations which may impose additional burdens on or may limit certain investors’ ability to purchase our
common stock, potentially making our common stock less attractive to investors.

In  October  2018,  the  U.S.  Department  of  Treasury  announced  a  pilot  program  to  implement  part  of  the  Foreign  Investment  Risk  Review
Modernization Act, or FIRRMA, effective November 10, 2018.  The pilot program expands the jurisdiction of the Committee on Foreign Investment in the
United States, or CFIUS, to include certain direct or indirect foreign investments in a defined category of U.S. companies, including companies involved in
manufacturing communications equipment.  Among other things, FIRRMA empowers CFIUS to require certain foreign investors to make mandatory filings
and permits CFIUS to charge filing fees related to such filings.  Such filings are subject to review by CFIUS.  Any such restrictions on the ability to purchase
shares of our common stock that have the effect of delaying or deterring a change in control could limit the opportunity for our stockholders to receive a
premium for their shares of our common stock and could also affect the price that some investors are willing to pay for our common stock.

Our management team has limited experience managing a public company.

Most members of our management team have limited experience managing a publicly traded company, interacting with public company investors and
complying  with  the  increasingly  complex  laws  pertaining  to  public  companies.  Our  management  team  may  not  successfully  or  efficiently  manage  our
transition to being a public company subject to significant regulatory oversight and reporting obligations under the federal securities laws and the scrutiny of
securities analysts and investors. These new obligations and constituents will require significant attention from our management team and could divert their
attention  away  from  the  day-to-day  management  of  our  business,  which  could  materially  adversely  affect  our  business,  financial  condition,  results  of
operations and prospects.

38

The requirements of being a public company may strain our resources, divert management’s attention and affect our ability to attract and retain qualified
board members.

As a public company, we are subject to the reporting requirements of the Exchange Act, the listing requirements of the Nasdaq Stock Market and
other applicable securities rules and regulations. Compliance with these rules and regulations will increase our legal and financial compliance costs, make
some activities more difficult, time-consuming or costly, and increase demand on our systems and resources, particularly after we are no longer an emerging
growth company. Among other things, the Exchange Act requires that we file annual, quarterly and current reports with respect to our business and results of
operations  and  maintain  effective  disclosure  controls  and  procedures  and  internal  control  over  financial  reporting.  In  order  to  maintain  and,  if  required,
improve  our  disclosure  controls  and  procedures  and  internal  control  over  financial  reporting  to  meet  this  standard,  significant  resources  and  management
oversight may be required. As a result, management’s attention may be diverted from other business concerns, which could harm our business and results of
operations. Although we have already hired additional employees to comply with these requirements, we may need to hire even more employees in the future,
which will increase our costs and expenses.

We are currently evaluating our internal controls, including to identify and remediate any deficiencies in those internal controls. We may not be able to
complete  our  evaluation,  testing  and  any  required  remediation  in  a  timely  fashion.  During  the  evaluation  and  testing  process,  if  we  identify  one  or  more
material  weaknesses  in  our  internal  control  over  financial  reporting  that  we  are  unable  to  remediate  before  the  end  of  the  same  fiscal  year  in  which  the
material weakness is identified, we will be unable to assert that our internal controls are effective. If we are unable to assert that our internal control over
financial  reporting  is  effective,  or  if  our  auditors  are  unable  to  attest  to  management’s  report  on  the  effectiveness  of  our  internal  controls,  which  will  be
required after we are no longer an emerging growth company, we could lose investor confidence in the accuracy and completeness of our financial reports,
which would cause the price of our common stock to decline.

In  addition,  changing  laws,  regulations  and  standards  relating  to  corporate  governance  and  public  disclosure  are  increasing  legal  and  financial
compliance costs and making some activities more time-consuming. We intend to invest resources to comply with evolving laws, regulations and standards,
and this investment may result in increased general and administrative expense and a diversion of management’s time and attention from revenue-generating
activities  to  compliance  activities.  If  our  efforts  to  comply  with  new  laws,  regulations  and  standards  differ  from  the  activities  intended  by  regulatory  or
governing bodies, regulatory authorities may initiate legal proceedings against us and our business may be harmed.

We  also  expect  that  being  a  public  company  will  make  it  more  expensive  for  us  to  obtain  director  and  officer  liability  insurance,  and  we  may  be
required to accept reduced coverage or incur substantially higher costs to obtain coverage. These factors could also make it more difficult for us to attract and
retain qualified members of our board of directors and qualified executive officers.

We estimate that we will incur approximately $2.0 to $3.0 million of annual costs associated with being a publicly traded company, which we expect
will be included in general and administrative expenses. However, it is possible that our actual costs of being a publicly traded company will be higher than
we currently estimate. In estimating these costs, we took into account expenses related to insurance, legal, accounting and compliance activities.

Item 1B. Unresolved Staff Comments.

None.

Item 2. Properties.

Facilities

Our corporate headquarters is located in Andover, Massachusetts and consists of approximately 122,000 square feet of space. We own the property
constituting our corporate headquarters, subject to an $8.0 million mortgage loan. The annual interest rate on the loan is 3.5%, and the loan is repayable in 60
monthly installments of principal and interest based on a 20-year amortization schedule. The remaining amount of unpaid principal under the loan is due on
the maturity date of July 1, 2020. The loan terms include annual affirmative, negative and financial covenants, including a requirement that we maintain a
minimum debt service ratio. We were in compliance with all annual covenants of the mortgage loan as of December 31, 2018. As of December 31, 2018,
outstanding borrowings under the mortgage loan were $7.0 million.

We lease additional facilities in Lawrence and Methuen, Massachusetts and Limerick, Ireland that we use for manufacturing, testing, logistics, and

customer support. We also lease a facility in Guangzhou, China that we use for

39

manufacturing,  testing,  logistics,  research  and  development  and  technical  support  and  a  facility  in  Valencia,  Spain  that  we  use  primarily  for  research  and
development.

We believe that our current facilities are adequate to meet our current needs. We anticipate expanding our facilities as we add employees and enter
new  geographic  markets.  We  believe  that  suitable  additional  or  alternative  space  will  be  available  on  acceptable  terms  as  needed  to  accommodate  future
growth.

Item 3. Legal Proceedings.

From  time  to  time,  we  are  a  party  to  various  litigation  matters  and  subject  to  claims  that  arise  in  the  ordinary  course  of  business  including,  for
example, patent infringement lawsuits by non-practicing entities. In addition, third parties may from time to time assert claims against us in the form of letters
and other communications. There is no pending or threatened legal proceeding to which we are a party that, in our opinion, is likely to have a material adverse
effect on our financial condition or results of operations. However, litigation is inherently unpredictable. Regardless of the outcome, litigation can adversely
affect us because of defense and settlement costs, diversion of management resources and other factors.

Item 4. Mine Safety Disclosures.

Not applicable.

PART II

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

Market Information

Our common stock trades on the Nasdaq Global Select Market under the symbol “CASA”. Trading of our common stock on the Nasdaq Global Select
Market commenced on December 15, 2017 in connection with our initial public offering, or IPO. Prior to that time, there was no established public trading
market for our common stock.  

Holders of Record

As of January 31, 2019, there were 21 holders of record of our common stock. Because many of our shares are held by brokers and other institutions

on behalf of stockholders, we are not able to estimate the number of stockholders represented by these record holders.

Performance Graph

This performance graph shall not be deemed to be “soliciting material” or to be “filed” with the U.S. Securities and Exchange Commission, or the
SEC,  for  purposes  of  Section  18  of  the  Securities  Exchange  Act  of  1934,  as  amended,  or  the  Exchange  Act,  or  otherwise  subject  to  liabilities  under  that
section, and shall not be deemed to be incorporated by reference into any of our filings under the Securities Act of 1933, as amended, or the Exchange Act,
except to the extent that we specifically incorporate it by reference into such filing.

The following graph compares the cumulative total return to stockholders for our common shares for the period from December 15, 2017 (the date our
common stock began trading on the Nasdaq Global Select Market) through December 31, 2018 with the Nasdaq Composite Index. The comparison assumes
an  investment  of  $100  is  made  on  December  15,  2017  in  our  common  shares  and  in  each  of  the  indices  and  in  the  case  of  the  indices  it  also  assumes
reinvestment of all dividends. The performance shown is not necessarily indicative of future performance.

On August 14, 2018, we announced that our board of directors authorized the repurchase of up to $75.0 million of our common stock under a stock
repurchase  program.   We  repurchased  and  retired  the  remaining  $29.4  million  of  shares  authorized  under  the  stock  repurchase  program  during  the
three-month  period  ended  December  31,  2018. The  stock  repurchase  program  had  no  expiration  date,  did  not  require  us  to  purchase  a  minimum
number of shares, and was able to be suspended, modified or discontinued at any time without prior notice.

Securities Authorized for Issuance Under Equity Compensation Plans

The  information  required  by  this  item  with  respect  to  our  equity  compensation  plans  is  expected  to  be  incorporated  by  reference  to  our  proxy

statement for the 2019 Annual Meeting of Stockholders to be filed with the SEC within 120 days of the fiscal year ended December 31, 2018.

Use of Proceeds

On December 19, 2017, we closed our initial public offering of common stock under a registration statement on Form S-1 (File No. 333-221658) that
was declared effective by the SEC on December 14, 2017.  The net offering proceeds to us from the offering, after deducting underwriting discounts of $6.3
million and offering expenses payable by us totaling $4.1 million, were approximately $79.3 million. No offering discounts, commissions or expenses were
paid directly or indirectly to any of our directors or officers (or their associates) or persons owning 10.0% or more of any class of our equity securities or to
any other affiliates. There has been no material change in the planned use of proceeds from our initial public offering as described in our final prospectus filed
with the SEC on December 15, 2017 pursuant to Rule 424(b)(4) promulgated under the Securities Act.  As of December 31, 2018, we had not used any of the
net  offering  proceeds  and  we  have  invested  the  proceeds  into  an  investment  portfolio  with  the  primary  objective  of  preserving  principal  and  providing
liquidity without significantly increasing risk.

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

The following discussion of our financial condition and results of operations should be read together with our consolidated financial statements and
related notes and other financial information included elsewhere in this Annual Report on Form 10-K. The following discussion contains forward-looking
statements  that  reflect  our  plans,  estimates  and  beliefs.  Our  actual  results  could  differ  materially  from  those  discussed  in  the  forward-looking  statements.
Factors that could cause or contribute to these differences include those discussed below and elsewhere in this Annual Report on Form 10-K, particularly in
the section titled “Risk Factors.”

Overview

Our  solutions  are  conceived,  designed,  and  built  to  solve  problems  faced  by  our  broadband  service  provider  customers  as  they  transform  their
networks to meet the growing demand for bandwidth and the introduction of new services.  We offer converged solutions for next-generation centralized,
distributed and virtualized architectures for cable broadband, fixed-line broadband and wireless networks. Our innovative products enable customers to cost-
effectively and dynamically increase network speed, add bandwidth capacity and new services for consumers and enterprises, reduce network complexity and
reduce operating and capital expenditures.

We have created a software-centric, multi-service portfolio based on our Axyom software which that enables a broad range of core and access network
functions for fixed and wireless networks. These networks share a common set of core and access network functions that enable network services such as
subscriber management, session management, transport security and radio frequency, or RF, management. Our Axyom software architecture allows each of
these  network  functions  to  be  provided  and  controlled,  integrated  or  combined  together,  by  a  distinct  segment  of  software,  which  can  be  integrated  or
combined  together  in  a  building  block-style  fashion  with  the  segments  of  software  responsible  for  each  other  network  function.  This  allows  us  to  offer
network  architectures  that  can  be  efficiently  and  rapidly  tailored  to  meet  each  customer’s  specific  requirements,  both  as  they  exist  at  the  time  of  initial
implementation and as they evolve over time. While we initially focused on providing solutions for cable service providers due to our founders’ experience in
the cable industry, the commonalities between new fixed and wireless network architectures have allowed us to leverage our existing Axyom software and to
expand our solutions into the wireless and fixed communications markets.

We  offer  a  scalable  solution  that  can  meet  the  evolving  bandwidth  needs  of  our  customers  and  their  subscribers.  Our  first  installation  in  a  service
provider’s network frequently involves deploying our broadband products in only a portion of the provider’s network and with only a fraction of the capacity
of our products enabled at the time of initial installation. Over time, our customers have generally expanded the use of our solutions to other areas of their
networks  to  increase  network  capacity.  Capacity  expansions  are  accomplished  either  by  deploying  additional  systems,  line  cards,  or  the  sale  of  additional
channels through the use of software. Sales of additional line cards and software-based capacity expansions generate higher gross margins than our initial
hardware-based deployments.

We  believe  that  the  shift  to  software-centric  ultra-broadband  networks  and  fixed  and  wireless  network  convergence  presents  us  with  a  compelling
market opportunity. We intend to maintain our technological leadership through the enhancement of existing products and the development of new products in
both our current and adjacent markets. By investing in research and development, we believe we will be well positioned to continue our rapid growth and take
advantage of the large market opportunity across fixed and wireless networks. We also intend to continue to expand our sales and marketing initiatives in key
geographies.

Our revenue growth is driven by technology upgrade cycles in our target markets and has been characterized by periods of rapid growth followed by
periods of more moderate growth in between these upgrade cycles. As an example, during 2014 to 2017 our revenue grew at a compound annual growth rate
of 18% while customers were purchasing both hardware (or integrated converged cable access platform, or CCAP) and software-based capacity from us and
upgrading their networks to DOCSIS 3.1.  In 2018, however, which we believe was a transition year prior to a new upgrade cycle, our revenue decreased by
15.5% to $297.1 million. We have been able to maintain strong levels of profitability throughout these upgrade cycles.  Our income from operations in 2016,
2017 and 2018 has been $114.8 million, $136.2 million and $79.0 million, respectively. Our solutions are commercially deployed in more than 70 countries
by more than 475 customers, including regional service providers as well as some of the world’s largest Tier 1 broadband service providers, serving millions
of subscribers.

Our Business Model

We  derive  revenue  from  sales  of  our  products  and  services.  To  date,  the  majority  of  our  product  revenue  has  come  from  sales  of  our  broadband
products, particularly our C100G CCAP solution, to cable operators worldwide. We generate service revenue primarily from sales of maintenance and support
services, which end customers typically purchase in conjunction with our products, and, to a lesser extent, from sales of professional services and extended
warranty services.

Since shipping our first products in 2005, our cumulative end-customer base has grown significantly. In particular, our revenue and installed base of
equipment  has  increased  significantly  with  the  introduction  of  our  CCAP  solution  in  2012  and  our  Data  Over  Cable  Service  Interface  Specification,  or
DOCSIS, 3.1 capabilities in 2015, both of which run on our Axyom software platform.

We offer a scalable solution that can meet the evolving bandwidth needs of our customers and their subscribers.

Our sales model focuses on the following key areas:

•

•

•

Adding  New  Customers.  With  several  thousand  broadband  service  providers  existing  globally,  we  believe  that  we  have  opportunities  for
growth by acquiring new customers in all of the geographic regions in which we compete. Potential new customers include broadband service
providers that provide fixed or wireless services or both. We intend to add new customers over time by continuing to invest in our technology
and our sales team to capitalize on these new opportunities. Our sales team works closely with prospective customers to educate them on and
demonstrate to them the technical and business merits of our products, including the ability to capture new revenue opportunities and realize
cost  savings  through  the  use  of  our  broadband  solutions.  We  build  relationships  with  prospective  customers  at  multiple  levels  and  within
numerous  departments  in  a  customer’s  organization  and,  through  the  sales  process,  we  strive  to  be  a  strategic  business  partner  for  our
customers. We believe that the technological strengths and capabilities of our broadband solutions and the introduction and implementation of
next-generation standards have been and will continue to be an important factor in our ability to add new customers.

Expanding Sales to Our Existing Customer Base.  Our  first  installation  in  a  service  provider’s  network  frequently  involves  deploying  our
broadband products in only a portion of the provider’s network and with only a fraction of the capacity of our products enabled at the time of
initial  installation.  Over  time,  our  customers  have  generally  expanded  the  use  of  our  solutions  to  other  areas  of  their  networks  to  increase
network capacity. Capacity expansions are accomplished either by deploying additional systems or line cards, or by our remote enablement of
additional channels through the use of software. Sales of additional line cards and software-based capacity expansions generate higher gross
margins than our initial hardware-based deployments.

We  work  with  our  existing  customers  to  identify  expansion  and  cross-selling  opportunities.  Existing  customers  are  familiar  with  and  have
benefited  from  the  operational  and  economic  benefits  of  our  broadband  products,  and  therefore,  sales  cycles  for  existing  customers  are
generally  shorter.  We  believe  expansion  and  cross-selling  opportunities  with  existing  customers  are  significant  given  their  existing  and
expected infrastructure spend as service providers leverage their investment in our platform to deliver new services to their customers.

Our solutions are commercially deployed in over 70 countries by more than 475 customers. We expect that a substantial portion of our future
sales will be follow-on sales to existing customers. During the years ended December 31, 2018, 2017 and 2016, sales to existing customers
represented  99%,  97%  and  74%  of  our  revenue,  respectively.  Our  business  and  results  of  operations  will  depend  on  our  ability  to  sell
additional products to our existing customer base.

Selling  New  Products.  Our  results  of  operations  have  been,  and  we  believe  will  continue  to  be,  affected  by  our  ability  to  quickly  and
effectively  design  and  sell  products  with  improved  performance  and  increased  functionality.  As  networks  and  standards  for  broadband
solutions  evolve,  we  aim  to  deliver  new  products  prior  to  our  competition.  For  example,  the  introduction  of  our  DOCSIS  3.0  broadband
solution, our CCAP solution and our DOCSIS 3.1 capabilities allowed us to obtain new customers, increase our sales to existing customers,
increase our revenue and capture market share. We aim to increase our revenue by enabling customers to transition from previously deployed
data  and  video  solutions  to  our  integrated  CCAP  solutions,  which  can  incorporate  DOCSIS  3.1  standards  as  well  as  our  remote-PHY
distributed access solution. Over the last several years, we have made substantial investments to extend our Axyom software platform and to
develop small cell solutions to serve the wireless market, and we expect to generate increased revenue in the future from sales of wireless
solutions to new and existing customers. Our ability to sustain our revenue growth will depend, in part, upon our sales of new products.

46

 
 
 
We market and sell our products and services through our direct global sales force, supported by sales agents, and through resellers. A majority of our
revenue  is  derived  from  direct  sales,  which  generate  higher  gross  margins  than  sales  made  through  resellers.  Our  sales  organization  includes  systems
engineers with deep technical expertise that provide pre-sales technical support. These systems engineers  also  assist  with  post-sales  support.  Our  resellers
receive  an  order  from  an  end  customer  prior  to  placing  an  order  with  us,  and  we  confirm  the  identification  of  or  are  aware  of  the  end  customer  prior  to
accepting such orders. We use sales agents to assist our direct global sales force in the sales process with certain customers primarily located in the Latin
America  and  Asia-Pacific  regions.  If  a  sales  agent  is  engaged  in  the  sales  process,  we  receive  the  order  directly  from  and  sell  the  products  and  services
directly to the end customer, and we pay a commission to the sales agent, calculated as a percentage of the related customer payment.

Each of our sales teams is responsible for a geographic territory and/or has responsibility for a number of major direct end-customer accounts. We
have a diverse, global customer base and our revenue by geographic region fluctuates from period to period based on the timing of customer projects. The
percentages of our revenue derived from customers in each geographic region were as follows:

We generate product revenue from sales of our software-centric broadband products, including our CCAP solution and our DOCSIS 3.1 capabilities.
The majority of our revenue is derived from sales of our CCAP solutions, particularly our C100G CCAP. We also generate product revenue from sales of
additional line cards and software-based capacity expansions.

We  generate  service  revenue  from  sales  of  initial  maintenance  and  support  services  contracts,  which  are  typically  purchased  by  end  customers  in
conjunction  with  our  products,  and  from  our  customers’  subsequent  annual  renewals  of  those  contracts.  We  offer  maintenance  and  support  services  under
renewable, fee-based contracts, which include telephone support and unspecified software upgrades and updates provided on a when-and-if-available basis.
To a lesser extent, we generate service revenue from sales of professional services, such as installation and configuration, and extended warranty services.

The sale of our software-centric broadband products generally includes a 90-day warranty on the software and a one-year warranty on the hardware
component  of  the  products,  which  includes  repair  or  replacement  of  the  applicable  hardware.  We  record  a  warranty  accrual  for  the  initial  software  and
hardware  warranty  included  with  our  product  sales  and  do  not  defer  revenue.  In  addition,  in  conjunction  with  customers’  renewals  of  maintenance  and
support services contracts, we offer an extended warranty for periods typically of one to three years for agreed-upon fees, which we record as service revenue.

Cost of Revenue

Our cost of product revenue consists primarily of the costs of procuring goods, such as chassis and line cards embedded with field programmable gate
arrays, or FPGAs, from our contract manufacturers and other suppliers. In addition, cost of product revenue includes salary and benefit expenses, including
stock-based compensation, for manufacturing and supply-chain management personnel, allocated facilities-related costs, estimated warranty costs, third-party
logistics costs, and estimated costs associated with excess and obsolete inventory.

Our cost of service revenue includes salary and benefit expenses, including stock-based compensation, for our maintenance and support services and

professional services personnel, fees incurred for subcontracted professional services provided to our customers, and allocated facilities-related costs.

Gross Profit

Our product gross profit and gross margin have been, and may in the future be, influenced by several factors, including changes in the volume of our
software-centric  broadband  products  sold,  product  configuration,  sales  of  capacity  expansions,  geographic  location  of  our  customers,  pricing  due  to
competitive  pressure,  estimated  warranty  costs,  inventory  obsolescence,  and  favorable  and  unfavorable  changes  in  inventory  production  volume  and
component costs. As some products mature, the average selling prices of those products may decline. Our service gross profit and gross margin have been,
and  may  in  the  future  be,  influenced  by  the  amount  and  timing  of  renewals  of  maintenance  and  support  services  contracts  by  customers,  pricing  due  to
competitive pressure and, to a lesser extent, the amount of professional services ordered by customers and performed by us. We expect that our gross margin
will  remain  relatively  stable  in  the  near  term,  subject  to  quarter-to-quarter  fluctuation,  due  to  changes  in  the  amount  of  our  software-centric  broadband
products and capacity expansions sold.

Operating Expenses

Our operating expenses consist of research and development, sales and marketing, and general and administrative expenses.

Research and Development Expenses

Research  and  development  expenses  consist  primarily  of  salary  and  benefit  expenses,  including  stock-based  compensation,  for  our  employees
engaged  in  research,  design  and  development  activities.  Research  and  development  expenses  also  include  project-specific  engineering  services  purchased
from  external  vendors,  prototype  costs,  depreciation  expense,  amortization  of  purchased  intellectual  property,  allocated  facilities-related  costs  and  travel
expenses.

We  expect  that  our  research  and  development  costs  will  increase  in  the  near  term  as  we  continue  to  make  significant  investments  to  enhance  our

software-centric broadband products and develop new software-centric broadband products and technologies, including our new wireless solutions.

Sales and Marketing Expenses

Sales  and  marketing  expenses  include  salary  and  benefit  expenses,  including  stock-based  compensation,  for  employees  and  costs  for  contractors
engaged  in  sales  and  marketing  activities.  Sales  and  marketing  expenses  also  include  commissions,  calculated  as  a  percentage  of  the  related  customer
payment, to sales agents that assist us in the sales process with certain customers primarily located in the Latin America and Asia-Pacific regions. These sales
agent commissions fluctuate from period to period based on the amount and timing of sales to the customers subject to sales agent commissions. Sales and
marketing  expenses  also  include  marketing  activities,  such  as  trade  shows,  marketing  programs  and  promotional  materials,  as  well  as  allocated  facilities-
related costs. We are also establishing a new sales force to sell and undertake new marketing programs to promote our new wireless solutions.

We expect that our sales and marketing expenses will increase in absolute dollars while remaining relatively stable as a percentage of revenue in the
near term as we continue to make investments in our sales and marketing organizations and expand our marketing programs and efforts to increase the market
awareness and sales of our products and services.

General and Administrative Expenses

General and administrative expenses include salary and benefit expenses, including stock-based compensation, for employees engaged in general and
administrative  activities,  as  well  as  professional  service  fees,  allocated  facilities-related  costs,  insurance,  travel  and  bad  debt  expenses  related  to  accounts
receivable.

We expect that our general and administrative expenses will increase in absolute dollars while remaining relatively stable as a percentage of revenue

in the near term primarily due to our continued growth and the increased cost associated with being a public company.

48

Other Income (Expense), Net

Other  income  (expense),  net  consists  of  interest  income  from  our  investments  in  short-term  financial  instruments,  such  as  certificates  of  deposit,
money market mutual funds and commercial paper, and interest expense associated with our term loan facility, the mortgage on our corporate office and debt
maintenance costs related to our revolving credit facility. Other income (expense), net also includes realized and unrealized gains and losses from foreign
currency transactions. We hedge certain significant transactions denominated in currencies other than the U.S. dollar, and we expect to continue to do so to
minimize our exposure to foreign currency fluctuations.

Provision for (Benefit from) Income Taxes

We are subject to income taxes in the United States and the foreign jurisdictions in which we do business. These foreign jurisdictions have statutory
tax  rates  different  from  those  in  the  United  States.  Our  effective  tax  rates  will  vary  depending  on  the  relative  proportion  of  foreign  to  U.S.  income,  the
utilization of foreign tax credits and research and development tax credits, changes in corporate structure, the amount and timing of certain employee stock-
based compensation transactions, changes in the valuation of our deferred tax assets and changes in tax laws and interpretations. We plan to regularly assess
the likelihood of outcomes that could result from the examination of our tax returns by the U.S. Internal Revenue Service, or IRS, and other tax authorities to
determine the adequacy of our income tax reserves and expense. Should actual events or results differ from our then-current expectations, charges or credits
to our provision for income taxes may become necessary. Any such adjustments could have a significant effect on our results of operations.

On December 22, 2017, the Tax Cuts and Jobs Act, or the TCJA, was enacted which, among other things, lowered the U.S. corporate income tax rate
to 21% from 35%, repealed the domestic production activity deductions, limited the deductibility of certain executive compensation and interest expense, and
established a modified territorial system requiring a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries. Beginning in 2018,
the TCJA also requires a minimum tax on certain future earnings generated by foreign subsidiaries while providing for future tax-free repatriation of such
earnings through a 100% dividends-received deduction. While the reduction in the U.S. corporate tax rate under the TCJA is not effective until 2018, under
GAAP, changes in tax rates are accounted for in the period enacted. Therefore, in accordance with Accounting Standards Codification, or ASC, Topic 740,
Income Taxes, and Staff Accounting Bulletin 118, we recognized a provisional income tax charge in the fourth quarter of 2017 of $14.1 million related to the
TCJA based on our initial analysis using available information and estimates. The provisional charge is comprised of $10.0 million related to the one-time
deemed repatriation of accumulated earnings of foreign subsidiaries and related withholding taxes and $4.1 million related primarily to the remeasurement of
net  deferred  tax  assets  as  a  result  of  the  reduction  in  the  U.S.  corporate  income  tax  rate  effected  by  the  TCJA.  As  a  result,  applicable  U.S.  corporate  and
foreign  income  taxes  have  been  provided  on  substantially  all  of  our  accumulated  earnings  of  foreign  subsidiaries  previously  considered  indefinitely
reinvested.   The Company’s accounting for the impacts of the TCJA is complete as of December 31, 2018, and the Company has not recorded any material
adjustments to the provisional amounts recorded in the fourth quarter of 2017 related to the TCJA.  Although the Company no longer considers these amounts
provisional, the determination of the TCJA’s income tax effects may change as a result of future legislation or further interpretation of the TCJA based on the
publication of regulations and guidance from the Internal Revenue Service and state tax authorities.

While  the  intent  of  TCJA  was  to  provide  for  a  territorial  tax  system,  effective  for  taxable  years  beginning  after  January  1,  2018,  taxpayers  are
subjected to the global intangible low-taxed income provisions, or GILTI provisions. The GILTI provisions require the Company to currently recognize in
U.S. taxable income, a deemed dividend inclusion of foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets.
During 2018 we recorded an income tax charge of $4.4 million related to GILTI.  The Company has made an accounting policy election, as allowed by the
SEC and FASB, to recognize the impacts of GILTI within the period incurred.  Therefore, no U.S. deferred taxes are provided on GILTI inclusions of future
foreign subsidiary earnings.

The decrease in product revenue was primarily due to a decrease in sales of our products to existing customers in North America, Latin America and
Asia-Pacific as a result of a decrease in the deployment of our software-centric broadband products in their networks, which we believe was primarily due to
the  timing  of  customer  expenditures  on  network  upgrades.  These  decreases  were  partially  offset  by  an  increase  in  sales  of  our  software-enabled  capacity
expansions to customers in Europe, Middle East and Africa.

The increase in service revenue was primarily due to a $1.0 million increase in maintenance and support services revenue due to customers renewing
their maintenance and support service contracts, partially offset by a $0.5 million decrease in professional services revenue due to a decrease in customer
projects requiring our assistance.

Liquidity and Capital Resources

Since  our  inception,  we  have  primarily  funded  our  operations  through  issuances  of  shares  of  our  convertible  preferred  stock  and  cash  flows  from
operations. In addition, on December 20, 2016, we entered into a credit agreement that included a term loan facility under which we borrowed $300.0 million
and in December 2017, we closed our initial public offering, or IPO, of 6,900,000 shares of common stock and received net proceeds of $79.3 million, after
deducting underwriting discounts, commissions and offering costs. The following tables set forth our cash, cash equivalents and marketable securities and
working capital as of December 31, 2018, 2017 and 2016 as well as our net cash flows for the years ended December 31, 2018, 2017 and 2016:

As  of  December  31,  2018,  we  had  cash  and  cash  equivalents  of  $280.6  million  and  net  accounts  receivable  of  $84.2  million.  We  maintain  a

$25.0 million revolving credit facility, which was unused as of December 31, 2018.

Of our total cash and cash equivalents of $280.6 million as of December 31, 2018, $77.1 million was held by our foreign subsidiaries. The TCJA
established a modified territorial system requiring a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries. In December 2017,
we recorded a provisional charge related to a one-time deemed repatriation of accumulated earnings of foreign subsidiaries and related withholding taxes. As
a  result,  applicable  U.S.  corporate  and  foreign  income  taxes  have  been  provided  on  substantially  all  of  our  accumulated  earnings  of  foreign  subsidiaries
previously considered indefinitely reinvested.  Beginning in 2018, the TCJA also requires a minimum tax on certain future earnings generated by foreign
subsidiaries while providing future tax-free repatriation of such earnings through a 100% dividends-received deduction. The Company’s accounting for the
impacts of the TCJA is complete as of December 31, 2018, and the Company has not recorded any material adjustments to the provisional amounts recorded
in the fourth quarter of 2017 related to the TCJA.  Although the Company no longer considers these amounts provisional, the determination of the TCJA’s
income tax effects may change as a result of future legislation or further interpretation of the TCJA based on the publication of regulations and guidance from
the Internal Revenue Service and state tax authorities.

While  the  intent  of  TCJA  was  to  provide  for  a  territorial  tax  system,  effective  for  taxable  years  beginning  after  January  1,  2018,  taxpayers  are
subjected to the GILTI provisions. The GILTI provisions require the Company to currently recognize in U.S. taxable income, a deemed dividend inclusion of
foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. During 2018 we recorded an income tax charge of $4.4
million related to GILTI.  The Company has made an accounting policy election, as allowed by the SEC and FASB, to recognize the impacts of GILTI within
the period incurred.  Therefore, no U.S. deferred taxes are provided on GILTI inclusions of future foreign subsidiary earnings.

We  believe  our  existing  cash  and  cash  equivalents,  anticipated  cash  flows  from  future  operations  and  liquidity  available  from  our  revolving  credit
facility will be sufficient to meet our working capital and capital expenditure needs and debt service obligations for at least the next 12 months. Our future
capital requirements may vary materially from those currently planned and will depend on many factors, including our rate of revenue growth, the timing and
extent of spending on research and development efforts and other business initiatives, purchases of capital equipment to support our growth, the expansion of
sales and marketing activities, expansion of our business through acquisitions or our investments in complementary products, technologies or businesses, the
use of working capital to purchase additional inventory, the timing of new product introductions, market acceptance of our products and overall economic
conditions. To the extent that current and anticipated future sources of liquidity are insufficient to fund our future business activities and requirements, we
may be required to seek additional equity or debt financing. In the event additional financing is required from outside sources, we may not be able to raise it
on terms acceptable to us or at all.

From our inception through December 31, 2018, our board of directors has declared a special dividend on five separate occasions and has approved
cash  payments  to  the  holders  of  our  stock  options,  stock  appreciation  rights,  or  SARs,  and  restricted  stock  units,  or  RSUs,  as  equitable  adjustments  in
connection with these special dividends. The dividend payments totaled $0.9 million, $206.4 million and $137.4 million in the years ended December 31,
2018, 2017 and 2016, respectively. The equitable adjustment payments totaled $7.3 million, $40.2 million and $4.9 million in the years ended December 31,
2018, 2017 and 2016, respectively. As of December 31, 2018, there were $3.3 million of equitable adjustment payments that had been approved by our board
of directors that had not yet been paid to the holders of our stock options, SARs and RSUs. These equitable adjustment payments will be paid to the holders
of the applicable equity awards as they vest through 2021. We do not anticipate declaring cash dividends in the foreseeable future. Any future determination
to declare dividends will be subject to the discretion of our board of directors and applicable law, and will depend on various factors, including our results of
operations, financial condition, prospects and any other factors deemed relevant by our board of directors.

Cash Flows

Operating Activities

Our  primary  source  of  cash  from  operating  activities  has  been  from  cash  collections  from  our  customers.  We  expect  cash  inflows  from  operating
activities to be affected by increases in sales and timing of collections and by purchases and shipments of inventory. Our primary uses of cash from operating
activities  have  been  for  personnel  costs  and  investment  in  sales  and  marketing  and  research  and  development.  We  expect  cash  outflows  from  operating
activities to increase as a result of further investment in research and development and sales and marketing and increases in personnel costs as we continue to
enhance our products and introduce new products in an effort to continue to expand our business.

57

During  the  year  ended  December  31,  2018,  cash  provided  by  operating  activities  was  $98.5  million,  primarily  resulting  from  our  net  income  of
$73.0 million, net non-cash gains of $0.7 million, and by net cash provided by changes in our operating assets and liabilities of $24.9 million. The net cash
provided  by  changes  in  our  operating  assets  and  liabilities  during  the  year  ended  December  31,  2018  was  primarily  due  to  a  $34.7  million  decrease  in
accounts receivable due to a decrease in sales and timing of the related collections; a $6.1 million increase in accrued expenses due to the timing of payments;
and a $4.2  million  increase  in  accounts  payable  primarily  attributable  to  timing  of  our  payments  for  purchases  of  inventory.  These  inflows  of  cash  were
partially offset by a $11.1 million increase in inventory due to anticipated growth in our business; a $5.1 million decrease in deferred revenue primarily due to
recognition of $6.2 million of revenue upon the product acceptance by a customer in Asia-Pacific, partially  offset  by  the  deferral  of  revenue  for  customer
acceptance; a  $3.1  million  decrease  in  accrued  income  taxes  primarily  due  to  federal  research  and  development  tax  credits  generated  in  2018  which  the
Company will carryback to reduce its long-term taxes payable related to the deemed repatriation tax under the TCJA; and a $1.1 million increase in prepaid
expenses and other current assets.

During  the  year  ended  December  31,  2017,  cash  provided  by  operating  activities  was  $95.0  million,  primarily  resulting  from  our  net  income  of
$88.5  million  and  net  non-cash  charges  of  $32.4  million,  both  partially  offset  by  net  cash  used  by  changes  in  our  operating  assets  and  liabilities  of
$25.9  million.  The  net  cash  used  by  changes  in  our  operating  assets  and  liabilities  during  the  year  ended  December  31,  2017  was  primarily  due  to  a
$25.7 million increase in accounts receivable due to an increase in sales and timing of the related collections; a $25.6 million decrease in deferred revenue
primarily  due  to  recognition  of  $14.4  million  of  revenue  upon  the  product  acceptance  by  a  customer  in  Asia-Pacific  and  recognition  of  $8.5  million  of
revenue upon the expiration of a trade-in right for a customer in North America; a $6.5 million decrease in accounts payable primarily attributable to timing
of our payments for purchases of inventory; and a $3.2 million decrease in accrued income taxes due to the timing of payments. These uses of cash were
partially offset by a $21.9 million decrease in inventory due to shipments of our software-centric broadband products to customers; a $10.2 million increase in
accrued  expenses  and  other  current  liabilities,  which  included  an  increase  of  $8.4  million  for  accrued  customer  incentives;  and  a  $3.5  million  decrease  in
prepaid expenses and other current assets.

During  the  year  ended  December  31,  2016,  cash  provided  by  operating  activities  was  $110.8  million,  primarily  resulting  from  our  net  income  of
$88.7 million, net non-cash charges of $9.1 million and net cash provided by changes in our operating assets and liabilities of $13.0 million. The net cash
provided by changes in our operating assets and liabilities during the year ended December 31, 2016 was primarily due to a $17.3 million increase in deferred
revenue due to the deferral of the revenue recognition for certain sales transactions due to customer acceptance provisions or future delivery obligations and
an increase in sales of maintenance and support service contracts as a result of an increase in our installed base; a $15.8 million increase in accrued expenses
and  other  current  liabilities,  which  included  an  increase  of  $15.4  million  for  accrued  customer  incentives;  a  $14.5  million  increase  in  accounts  payable
primarily attributable to timing of our payments for purchases of inventory; and a $6.9 million increase in accrued income taxes as a result of an increase in
taxable  income.  These  sources  of  cash  were  partially  offset  by  a  $22.8  million  increase  in  inventory  due  to  the  anticipated  growth  in  our  business  and  a
$16.3 million increase in accounts receivable due to an increase in sales and timing of the related collections.

Investing Activities

Our investing activities have consisted primarily of expenditures for lab and computer equipment and software to support the development of new
products and increase our manufacturing capacity to meet customer demand for our products. In addition, our investing activities include expansion of and
improvements to our facilities. As our business expands, we expect that we will continue to invest in these areas.

Net  cash  used  in  investing  activities  during  the  year  ended  December  31,  2018  was  $8.0  million  and  consisted  of  purchases  of  property  and

equipment.

Net cash provided by investing activities during the year ended December 31, 2017 was $7.6 million and consisted of $14.6 million of proceeds from

maturities of marketable securities, partially offset by $7.0 million for purchases of property and equipment.

Net  cash  used  in  investing  activities  during  the  year  ended  December  31,  2016  was  $21.8  million  and  consisted  of  $14.4  million  for  purchases  of

marketable securities and $7.4 million for purchases of property and equipment.

58

Financing Activities

Net cash used in financing activities during the year ended December 31, 2018 was $68.3 million and consisted of repurchases of common stock of
$75.1  million,  dividend  and  equitable  adjustment  payments  of  $7.3  million,  debt  principal  repayments  of  $3.3  million  and  offering  costs  of  $1.1  million,
partially offset by proceeds from the exercise of stock options of $14.7 million and profit disgorgement of $3.8 million by certain selling stockholders in our
follow-on public offering.

Net cash used in financing activities during the year ended December 31, 2017 was $172.7 million and consisted primarily of dividend and equitable
adjustment  payments  of  $246.6  million,  payment  of  taxes  on  behalf  of  our  employees  related  to  net  share  settlement  of  equity  awards  of  $4.0  million,
principal repayments of our term loan facility and commercial mortgage of $3.3 million and payments of initial public offering costs of $2.4 million, partially
offset by proceeds received from our initial public offering, net of underwriting discounts and commissions, of $83.4 million and proceeds from the exercise
of stock options of $0.3 million.

Net cash provided by financing activities during the year ended December 31, 2016 was $149.4 million and consisted primarily of net proceeds from
borrowings under our term loan facility of $292.2 million and proceeds from the exercise of stock options of $0.6 million, both partially offset by dividend
and equitable adjustment payments of $142.3 million and payments of initial public offering costs of $0.5 million.

Commercial Mortgage Loan

In  July  2015,  we  entered  into  an  $8.0  million  commercial  mortgage  loan  agreement.  The  annual  interest  rate  on  the  loan  is  3.5%,  and  the  loan  is
repayable in 60 monthly installments of principal and interest based on a 20-year amortization schedule. The loan is secured by the land and building, which
are our corporate offices, purchased in March 2015, and contains annual affirmative, negative and financial covenants, including maintenance of a minimum
debt service ratio. We were in compliance with all the covenants of the mortgage loan as of December 31, 2018 and 2017. As of December 31, 2018 and
2017, the outstanding principal amount under the mortgage loan was $7.0 million and $7.3 million, respectively.

Term Loan and Revolving Credit Facilities

On December 20, 2016, we entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, various lenders and JPMorgan

Chase Bank, N.A. and Barclays Bank PLC, as joint lead arrangers and joint bookrunners, providing for:

•

•

a term loan facility of $300.0 million and

a revolving credit facility of up to $25.0 million in revolving credit loans and letters of credit.

As of December 31, 2018 and 2017, we had borrowings of $294.0 million and $297.0 million, respectively, outstanding under the term loan facility
and we did not have any outstanding borrowings under the revolving credit facility; however, as of December 31, 2017, we had used $1.0 million under the
revolving credit facility for a stand-by letter of credit that served as collateral for a stand-by letter of credit issued by Bank of America to one of our customers
pursuant to a contractual performance guarantee. As of December 31, 2018, the stand-by letter of credit that served as collateral was terminated, and we did
not use any amount under the revolving credit facility. In addition, we may, subject to certain conditions, including the consent of the administrative agent and
the institutions providing such increases, increase the facilities by an unlimited amount so long as we are in compliance with specified leverage ratios, or
otherwise by up to $70.0 million.

Borrowings under the facilities bear interest at a floating rate, which can be either a Eurodollar rate plus an applicable margin or, at our option, a base
rate (defined as the highest of (x) the JPMorgan Chase, N.A. prime rate, (y) the federal funds effective rate, plus one-half percent (0.50%) per annum and (z) a
one-month Eurodollar rate plus 1.00% per annum) plus an applicable margin. The applicable margin for borrowings under the term loan facility is 4.00% per
annum for Eurodollar rate loans (subject to a 1.00% per annum interest rate floor) and 3.00% per annum for base rate loans. As a result of the completion of
our initial public offering in December 2017, the applicable margin for borrowings under the revolving credit facility is 1.75% per annum for Eurodollar rate
loans and 0.75% per annum for base rate loans, subject to reduction based on our maintaining of specified net leverage ratios. The interest rates payable under
the facilities are subject to an increase of 2.00% per annum during the continuance of any payment default.

59

 
 
For Eurodollar rate loans, we may select interest periods of one, two, three or six months or, with the consent of all relevant affected lenders, twelve
months.  Interest  will  be  payable  at  the  end  of  the  selected  interest  period,  but  no  less  frequently  than  every  three  months  within  the  selected  interest  period.
Interest on any base rate loan is not set for any specified period and is payable quarterly. We have the right to convert Eurodollar rate loans into base rate loans
and  the  right  to  convert  base  rate  loans  into  Eurodollar  rate  loans  at  our  option,  subject,  in  the  case  of  Eurodollar  rate  loans,  to  prepayment  penalties  if  the
conversion is effected prior to the end of the applicable interest period. As of December 31, 2018, the interest rate on our borrowings under the term loan facility
was 6.52% per annum, which was based on a one-month Eurodollar rate of 2.52% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate
loans. As of December 31, 2017, the interest rate on the term loans was 5.69% per annum, which was based on a three-month Eurodollar rate at the applicable
floor of 1.69% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans.

The revolving credit facility also requires payment of quarterly commitment fees at a rate of 0.25% per annum on the difference between committed

amounts and amounts actually borrowed under the facility and customary letter of credit fees.

The term loan facility matures on December 20, 2023 and the revolving credit facility matures on December 20, 2021. The term loan facility is subject
to  amortization  in  equal  quarterly  installments,  which  commenced  on  March  31,  2017,  of  principal  in  an  annual  aggregate  amount  equal  to  1.0%  of  the
original principal amount of the term loans of $300.0 million, with the remaining outstanding balance payable at the date of maturity.

Voluntary prepayments of principal amounts outstanding under the term loan facility are permitted at any time; however, if a prepayment of principal
is made with respect to a Eurodollar loan on a date other than the last day of the applicable interest period, we are required to compensate the lenders for any
funding losses and expenses incurred as a result of the prepayment. Prior to the revolving credit facility maturity date, funds borrowed under the revolving
credit facility may be borrowed, repaid and reborrowed, without premium or penalty.

In addition, we are required to make mandatory prepayments under the facilities with respect to (i) 100% of the net cash proceeds from certain asset
dispositions (including casualty and condemnation events) by us or certain of our subsidiaries, subject to certain exceptions and reinvestment provisions, (ii)
100% of the net cash proceeds from the issuance or incurrence of any additional debt by us or certain of our subsidiaries, subject to certain exceptions, and
(iii) 50% of our excess cash flow, as defined in the credit agreement, subject to reduction upon our achievement of specified performance targets.

The facilities are secured by, among other things, a first priority security interest, subject to permitted liens, in substantially all of our assets and all of
the assets of certain of our subsidiaries and a pledge of certain of the stock of certain of our subsidiaries, in each case subject to specified exceptions. The
facilities  contain  customary  affirmative  and  negative  covenants,  including  certain  restrictions  on  our  ability  to  pay  dividends,  and,  with  respect  to  the
revolving credit facility, a financial covenant requiring us to maintain a specified total net leverage ratio in the event that on the last day of any fiscal quarter
we have utilized more than 30% of our borrowing capacity under the facility. We were in compliance with all of the applicable covenants of the facilities as of
December 31, 2018 and 2017. As of December 31, 2018 and 2017, we had not utilized more than 30% of our borrowing capacity under the revolving credit
facility and compliance with the financial covenant was not applicable.

In connection with entering into the facilities in December 2016, we terminated our revolving credit facility with Bank of America. We did not have

any outstanding borrowings under the Bank of America revolving credit facility at the time of termination.

Stock Repurchase Program

On August 14, 2018, we announced that our board of directors authorized the repurchase of up to $75.0 million of our common stock. During the year
ended December 31, 2018, we repurchased and retired 5.2 million shares of our common stock for $75.0 million, before commissions. Stock repurchases
under this program are now complete. The stock repurchase program had no expiration date, did not require us to purchase a minimum number of shares, and
was able to be suspended, modified or discontinued at any time without prior notice.

Amounts in the table reflect the contractually required principal and interest payable pursuant to outstanding borrowings under our term loan facility.
For purposes of this table, the interest due under the term loan facility was calculated using an assumed interest rate of 6.52% per annum, which was
the interest rate in effect as of December 31, 2018.
Amounts  in  the  table  reflect  the  contractually  required  principal  and  interest  payable  pursuant  to  outstanding  borrowings  under  our  commercial
mortgage.
Amounts in the table reflect payments due for our lease of manufacturing, warehouse and office space in the United States, China, Spain and Ireland
under non-cancelable operating leases that expire in 2021, 2022, 2022 and 2026, respectively. The Ireland lease provides us the right to terminate in
2021.

We  enter  into  purchase  agreements  with  our  contract  manufacturers  and  suppliers,  generally  with  terms  of  a  year  or  more. We  have  no  minimum

purchase requirements under these agreements.

The  contractual  obligations  table  above  excludes  $1.9  million  of  long-term  taxes  payable  related  to  the  mandatory  deemed  repatriation  tax  on

undistributed earnings of foreign subsidiaries under the TCJA.

Critical Accounting Policies and Significant Judgments and Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements included
elsewhere in this Annual Report on Form 10-K, which have been prepared in accordance with accounting principles generally accepted in the United States of
America, or GAAP. In preparing our consolidated financial statements, we make estimates, assumptions and judgments that can have a significant effect on
our reported revenue, results of operations and net income or loss, as well as on the value of certain assets and liabilities on our balance sheet during and as of
the reporting periods. These estimates, assumptions and judgments are necessary because future events and their effects on our results and the value of our
assets cannot be determined with certainty and are made based on our historical experience and on other assumptions that we believe to be reasonable under
the  circumstances.  We  evaluate  our  estimates  and  assumptions  on  an  ongoing  basis.  These  estimates  may  change  as  new  events  occur  or  additional
information is obtained, and we may periodically be faced with uncertainties, the outcomes of which are not within our control and may not be known for a
prolonged period of time. As the use of estimates is inherent in the financial reporting process, actual results could differ from those estimates.

While our significant accounting policies are described in more detail in Note 2 to our consolidated financial statements included elsewhere in this
Annual Report on Form 10-K, we believe that the following accounting policies are those most critical to the judgments and estimates used in the preparation
of our consolidated financial statements.

Revenue Recognition

We generate revenue from sales of our broadband products, along with associated maintenance and support services, and, to a lesser extent, from sales
of professional services and extended warranty services. We also generate revenue from sales of additional line cards and software-based capacity expansions.
Maintenance and support services include telephone support and unspecified software upgrades and updates provided on a when-and-if-available basis.

In  our  consolidated  statements  of  operations  and  comprehensive  income,  revenue  from  sales  of  broadband  products  and  capacity  expansions  is
classified  as  product  revenue,  and  revenue  from  maintenance  and  support,  professional  services  and  extended  warranty  services  is  classified  as  service
revenue.

61

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
   
   
 
 
We recognize revenue from sales when the following revenue recognition criteria are met:

•

•

•

•

Persuasive  evidence  of  an  arrangement  exists.  Binding  contracts  and/or  customer  purchase  orders  are  generally  evidence  of  an
arrangement.  For  professional  services,  evidence  of  an  arrangement  may  also  include  information  documenting  the  scope  of  work  to  be
performed, and customer acceptance terms, if any.

Delivery  has  occurred.  For  broadband  products,  shipping  documents  and  customer  acceptance,  if  applicable,  verify  that  delivery  has
occurred.  For  software-enabled  capacity  expansions,  delivery  occurs  when  the  additional  bandwidth  capacity  is  made  available  to  the
customer. For professional services, delivery occurs as the services are completed.

The sales price is fixed or determinable. The sales price is considered fixed or determinable when the fees have been contractually agreed with
the customer and are not deemed to be subject to refund, adjustment or future discounts, and when the payment terms of the transaction do not
extend beyond our customary payment terms, which are one year or less.

Collectibility is reasonably assured. We assess the ability to collect from our customers based on a number of factors that generally include
information supplied by credit agencies, references and/or analysis of customer accounts and payment history. If collection from a customer is
not considered reasonably assured, all revenue related to the customer arrangement is deferred until payment is received and all other revenue
recognition criteria have been met.

When customer acceptance of the product is required and is other than perfunctory, revenue for the entire customer arrangement is deferred until the

acceptance has been received.

Our  products  have  both  software  and  non-software  (i.e.,  hardware)  components  that  function  together  to  deliver  the  products’  essential
functionality. In addition, the hardware sold generally cannot be used apart from the embedded software. As a result, all of our product and service offerings
are excluded from the scope of software revenue recognition requirements and instead fall within the scope of ASC Topic 605, Revenue Recognition.

Many of our sales involve multiple-deliverable arrangements that include products and maintenance and support services and, on a limited basis, may
also  include  professional  services  and  extended  warranty  services. We  have  determined  that  our  products,  maintenance  and  support  services,  professional
services and extended warranty services have standalone value to the customer because each of these deliverables is sold separately to our customers or, in the
case of professional services, is sold separately by other vendors. As a result, we treat each of these deliverables as a separate unit of accounting for purposes
of allocating the arrangement fee and recognizing the revenue of each unit.

For  our  multiple-deliverable  arrangements,  we  allocate  the  arrangement  fee  to  each  deliverable  based  on  the  relative  selling  prices  of  each  of  the
deliverables in the arrangement using the selling price hierarchy. In such circumstances, we determine the selling price of each deliverable based on vendor-
specific objective evidence, or VSOE, of selling price, if it exists; otherwise, third-party evidence, or TPE, of selling price. If neither VSOE nor TPE exists,
we use our best estimate of the selling price, or BESP, for the deliverable. We limit the amount of the arrangement fee allocated to deliverables to the amount
that is not contingent on the future delivery of products or services or future performance obligations and the amount that is not subject to customer-specific
return or refund privileges.

To date, we have not been able to establish VSOE of selling price of any of our products, maintenance and support services, professional services or
extended warranty services because we have not established a history of consistently pricing each product or service within a narrow range. In addition, we
are not able to determine TPE of selling price for our products or services because our various product and service offerings contain a significant level of
differentiation and, therefore, comparable pricing of competitors’ products and services with similar functionality cannot be obtained. As we are unable to
establish selling price using VSOE or TPE, we use BESP to allocate the arrangement fee to products, maintenance and support services, professional services
and extended warranty services in multiple-deliverable arrangements. The objective of BESP is to determine the price at which we would transact a sale if a
product  or  service  was  sold  on  a  standalone  basis.  We  determine  BESP  of  selling  price  for  our  products  and  services  by  considering  multiple  factors,
including, but not limited to, our historical pricing practices by customer type and geographic-specific market factors.

Revenue from product sales is recognized upon delivery to the customer, or upon the later receipt of customer acceptance of the product when such

acceptance is required.

62

 
 
 
 
Revenue from maintenance and support services is recognized ratably over the contract period, which is typically one year, but can be as long as three
or five years. When customer acceptance of a product is required, the recognition of any associated maintenance and support services revenue commences
only upon customer acceptance of the associated product. Revenue from extended warranty services is recognized ratably over the contract period, which is
typically one to three years.

Revenue from professional services is recognized as the services are performed. Professional services generally include installation or configuration
services  that  are  not  deemed  to  be  essential  to  the  functionality  of  the  products. When  customer  acceptance  is  required,  the  recognition  of  any  associated
professional services revenue is deferred until the associated product and/or professional service is accepted by the customer.

Resellers

We market and sell our products through our direct global sales force, supported by sales agents, and through resellers. Our resellers receive an order
from an end customer prior to placing an order with us, and we confirm the identification of or are aware of the end customer prior to accepting such order.
We invoice the reseller an amount that reflects a reseller discount and record revenue based on the amount of the discounted arrangement fee. Our resellers do
not stock inventory received from us.

When we transact with a reseller, our contractual arrangement is with the reseller and not with the end customer. Whether we transact business with
and receive the order from a reseller or directly from an end customer, our revenue recognition policy and resulting pattern of revenue recognition for the
order are the same.

We also use sales agents that assist us in the sales process with certain customers primarily located in the Latin America and Asia-Pacific regions.
Sales agents are not resellers. If a sales agent is engaged in the sales process, we receive the order directly from and sell the products and services directly to
the  end  customer,  and  we  pay  a  commission  to  the  sales  agent,  calculated  as  a  percentage  of  the  related  customer  payment.  Sales  agent  commissions  are
recorded  as  expenses  when  incurred  and  are  classified  as  sales  and  marketing  expenses  in  our  consolidated  statements  of  operations  and  comprehensive
income.

Deferred Revenue

Amounts billed in excess of revenue recognized are recorded as deferred revenue. Deferred revenue includes customer deposits, amounts billed for
maintenance and support services contracts in advance of services being performed, amounts for trade-in right liabilities and amounts related to arrangements
that have been deferred as a result of not meeting the required revenue recognition criteria as of the end of the reporting period. Deferred revenue expected to
be recognized as revenue more than one year subsequent to the balance sheet date is reported within long-term liabilities in our consolidated balance sheets.

When the payment terms of a customer order extend beyond our customary payment terms, which are one year or less, we consider the arrangement to
be  an  extended  payment  term  arrangement  and  conclude  that  the  sales  price  is  not  fixed  or  determinable  for  revenue  recognition  purposes.  In  these
circumstances, we defer all revenue of the arrangement and only recognize revenue to the extent of the payment amounts that become due, provided that all
other revenue recognition criteria have been met.

We defer recognition of incremental direct costs, such as cost of goods and services, until recognition of the related revenue. Such costs are classified
as current assets if the related deferred revenue is classified as current, and such costs are classified as non-current assets if the related deferred revenue is
classified as non-current.

Other Revenue Recognition Policies

In  limited  instances,  we  have  offered  future  rebates  to  customers  based  on  a  fixed  or  variable  percentage  of  actual  sales  volumes  over  specified
periods. The future rebates earned based on the customer’s purchasing from us in one period may be used as credits to be applied by them against accounts
receivable due to us in later periods. We account for these future rebates as a reduction of the revenue recorded for the customer’s current purchasing activity
giving rise to the future rebates. The liability for these future rebates is recorded as accrued customer incentives (within accrued expenses and other current
liabilities) until the credits have been applied by the customer against accounts receivable due to us or the credits expire.

63

When future trade-in rights are granted to customers at the time of sale, we defer a portion of the revenue recognized for the sale and account for it as
a guarantee at fair value until the trade-in right is exercised or the right expires, in accordance with ASC Topic 460, Guarantees. Determining the fair value of
the trade-in right requires us to estimate the probability of the trade-in right being exercised and the future value of the product upon trade-in. We assess and
update  these  estimates  at  each  reporting  period,  and  our  updates  to  these  estimates  may  result  in  either  an  increase  or  decrease  in  the  amount  of  revenue
deferred.

Billings to customers for shipping costs and reimbursement of out-of-pocket expenses, including travel, lodging and meals, are recorded as revenue,

and the associated costs incurred by us for those items are recorded as cost of revenue.

We exclude any taxes assessed by a governmental authority that are directly imposed on a revenue-producing transaction (e.g., sales, use and value

added taxes) from our revenue and costs.

Inventories

Inventories  are  valued  at  the  lower  of  cost  or  market  value.  Cost  is  computed  using  the  first-in  first-out  convention.  Inventories  are  composed  of
hardware and related component parts of finished goods. We establish provisions for excess and obsolete inventories after evaluating historical sales, future
demand, market conditions, expected product life cycles, and current inventory levels to reduce such inventories to their estimated net realizable value. Such
provisions are made in the normal course of business and charged to cost of revenue in our consolidated statements of operations and comprehensive income.

Deferred inventory costs are included within inventory in our consolidated balance sheets. Deferred inventory costs represent the cost of products that
have  been  delivered  to  the  customer  for  which  revenue  associated  with  the  arrangement  has  been  deferred  as  a  result  of  not  meeting  all  of  the  required
revenue  recognition  criteria,  such  as  receipt  of  customer  acceptance.  Until  the  revenue  recognition  criteria  are  met,  we  retain  the  right  to  a  return  of  the
underlying  inventory.  Deferred  inventory  costs  are  recognized  as  cost  of  revenue  in  our  consolidated  statements  of  operations  and  comprehensive  income
when the related revenue is recognized.

Product Warranties

Substantially all of our products are covered by a warranty for software and hardware for periods ranging from 90 days to one year. In addition, in
conjunction with customers’ renewals of maintenance and support contracts, we offer an extended warranty for periods typically of one to three years for
agreed-upon fees. In the event of a failure of a hardware product or software covered by these warranties, we must repair or replace the software or hardware
or,  if  those  remedies  are  insufficient,  provide  a  refund  at  our  discretion.  Our  warranty  reserve,  which  is  included  in  accrued  expenses  and  other  current
liabilities in our consolidated balance sheets, reflects estimated material, labor and other costs related to potential or actual software and hardware warranty
claims for which we expect to incur an obligation. Our estimates of anticipated rates of warranty claims and the costs associated therewith are primarily based
on  historical  information  and  future  forecasts.  We  periodically  assess  the  adequacy  of  the  warranty  reserve  and  adjust  the  amount  as  necessary.  If  the
historical data used to calculate the adequacy of the warranty reserve are not indicative of future requirements, additional or reduced warranty reserves may
be required.

Derivative Instruments

We have certain international customers that are billed in foreign currencies. To mitigate the volatility related to fluctuations in the foreign exchange
rates  for  accounts  receivable  denominated  in  foreign  currencies,  we  enter  into  foreign  currency  forward  contracts.  We  do  not  use  derivative  financial
instruments for speculative purposes. As of December 31, 2018, we had foreign currency forward contracts outstanding with notional amounts totaling 25.7
million euros maturing in the fiscal year ending December 31, 2019. As of December 31, 2017, we had foreign currency forward contracts outstanding with
notional amounts totaling 5.9 million euros maturing in the fiscal year ending December 31, 2018.

Our  foreign  currency  forward  contracts  economically  hedge  certain  risk  but  are  not  designated  as  hedges  for  financial  reporting  purposes,  and
accordingly,  all  changes  in  the  fair  value  of  these  derivative  instruments  are  recorded  as  unrealized  foreign  currency  transaction  gains  or  losses  in  our
consolidated  statements  of  operations  and  comprehensive  income  as  a  component  of  other  income  (expense).  We  record  all  derivative  instruments  in  the
consolidated balance sheet at their fair values. As of December 31, 2018, we recorded an asset of $0.3 million and as of December 31, 2018 and 2017, we
recorded a liability of $0.3 million and $0.2 million, respectively, related to outstanding foreign currency forward contracts, which were included in prepaid
expenses and other current assets and in accrued expenses and other current liabilities, respectively, in the consolidated balance sheet. No asset was recorded
as of December 31, 2017.

64

Income Taxes

We account for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected
future  tax  consequences  of  temporary  differences  between  the  financial  statement  and  tax  basis  of  assets  and  liabilities,  as  measured  by  enacted  tax  rates
anticipated to be in effect when these differences reverse. This method also requires the recognition of future tax benefits to the extent that realization of such
benefits is more likely than not. Deferred tax expense or benefit is the result of changes in the deferred tax assets and liabilities. We assess the likelihood that
our deferred tax assets will be recovered from future taxable income and, to the extent we believe, based upon the weight of available evidence, that it is more
likely than not that all or a portion of the deferred tax assets will not be realized, we establish a valuation allowance through a charge to income tax expense.
We  evaluate  the  potential  for  recovery  of  deferred  tax  assets  by  estimating  the  future  taxable  profits  expected  and  considering  prudent  and  feasible  tax
planning strategies.

We record a liability for potential payments of taxes to various tax authorities related to uncertain tax positions and other tax matters. The recorded
liability is based on a determination of whether and how much of a tax benefit in our tax filings or positions is more likely than not to be realized. The amount
of the benefit that may be recognized in the financial statements is the largest amount that has a greater than 50% likelihood of being realized upon ultimate
settlement. To the extent that the assessment of such tax positions changes, the change in estimate is recorded in the period in which the determination is
made. We establish a liability, which is included in accrued income taxes in our consolidated balance sheets, for tax-related uncertainties based on estimates
of whether, and the extent to which, additional taxes will be due. These liabilities are established when we believe that certain positions might be challenged
despite  our  belief  that  the  tax  return  positions  are  fully  supportable.  We  adjust  the  recorded  liability  in  light  of  changing  facts  and  circumstances.  Our
provision for income taxes includes the impact of the recorded liability and changes thereto.

We recognize interest and penalties related to uncertain tax positions within other income (expense) in our consolidated statements of operations and

comprehensive income. Accrued interest and penalties are included in accrued income taxes in our consolidated balance sheets.

On December 22, 2017, the TCJA was enacted which, among other things, lowered the U.S. corporate income tax rate to 21% from 35%, repealed the
domestic  production  activity  deductions,  limited  the  deductibility  of  certain  executive  compensation  and  interest  expense,  and  established  a  modified
territorial system requiring a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries. Beginning in 2018, the TCJA also requires
a minimum tax on certain future earnings generated by foreign subsidiaries while providing for future tax-free repatriation of such earnings through a 100%
dividends-received deduction. While the reduction in the U.S. corporate tax rate under the TCJA is not effective until 2018, under GAAP, changes in tax rates
are accounted for in the period enacted. As a result of the TCJA, applicable U.S. and foreign taxes have been provided on substantially all of our accumulated
earnings  of  foreign  subsidiaries  previously  considered  indefinitely  reinvested.  The  Company’s  accounting  for  the  impacts  of  the  TCJA  is  complete  as  of
December 31, 2018, and the Company has not recorded any material adjustments to the provisional amounts recorded in the fourth quarter of 2017 related to
the TCJA.  Although the Company no longer considers these amounts provisional, the determination of the TCJA’s income tax effects may change as a result
of future legislation or further interpretation of the TCJA based on the publication of regulations and guidance from the Internal Revenue Service and state tax
authorities.

While  the  intent  of  TCJA  was  to  provide  for  a  territorial  tax  system,  effective  for  taxable  years  beginning  after  January  1,  2018,  taxpayers  are
subjected to the GILTI provisions. The GILTI provisions require the Company to currently recognize in U.S. taxable income a deemed dividend inclusion of
foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. During 2018 we recorded an income tax charge of $4.4
million related to GILTI.  The Company has made an accounting policy election, as allowed by the SEC and FASB, to recognize the impacts of GILTI within
the period incurred.  Therefore, no U.S. deferred taxes are provided on GILTI inclusions of future foreign subsidiary earnings.

Stock-Based Compensation

We  measure  stock  options  and  other  stock-based  awards  granted  to  employees  and  directors  based  on  the  fair  value  on  the  date  of  the  grant  and
recognize compensation expense of those awards, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the
respective award. Generally, we issue stock options with only service-based vesting conditions and record the expense for these awards using the straight-line
method.

65

For stock-based awards granted to non-employee consultants, compensation expense is recognized over the period during which services are rendered
by such non-employee consultants until completed. At the end of each financial reporting period prior to completion of the service, the fair value of these
awards is remeasured using the then-current fair value of our common stock and updated assumption inputs in the Black-Scholes option-pricing model.

We have also granted SARs to certain employees, which require us to pay in cash upon exercise an amount equal to the product of the excess of the
per share fair market value of our common stock on the date of exercise over the exercise price, multiplied by the number of shares of common stock with
respect  to  which  the  SAR  is  exercised.  Because  these  awards  may  require  us  to  settle  the  awards  in  cash,  they  are  accounted  for  as  a  liability  in  our
consolidated  balance  sheets.  The  liability  related  to  these  awards,  as  well  as  related  compensation  expense,  is  recognized  over  the  period  during  which
services  are  rendered  until  completed.  Changes  in  the  fair  value  of  the  SAR  liability  are  estimated  using  the  Black-Scholes  option  pricing  model  and  are
recorded in our consolidated statements of operations and comprehensive income. After vesting is completed, we will continue to remeasure the fair market
value of the liability until the award is either exercised or canceled, with changes in the fair value of the liability recorded in our consolidated statements of
operations and comprehensive income.

We estimate the fair value of each stock option and SAR grant using the Black-Scholes option-pricing model, which uses as inputs the fair value of
our common stock and assumptions we make for the volatility of our common stock, the expected term of the award, the risk-free interest rate for a period
that approximates the expected term of our stock options and our expected dividend yield.

Determination of Fair Value of Common Stock on Grant Dates prior to our Initial Public Offering

Given the absence of an active market for our common stock prior to our initial public offering, the estimated fair value of our common stock was
determined by our board of directors at the time of each award grant based upon several factors, including its consideration of input from management, our
most recently available third-party valuations of common stock and our board of directors’ assessment of additional objective and subjective factors that it
believed were relevant and which may have changed from the date of the most recent valuation through the date of the grant. These third-party valuations
were  performed  in  accordance  with  the  guidance  outlined  in  the  American  Institute  of  Certified  Public  Accountants’  Accounting  and  Valuation  Guide,
Valuation of Privately-Held-Company Equity Securities Issued as Compensation using either the hybrid method or the option-pricing method, or OPM, which
used  a  combination  of  income  and  market  approaches  to  estimate  our  enterprise  value.  Cash  is  added  and  interest-bearing  debt  is  subtracted  from  the
estimated enterprise value in order to estimate the underlying equity value. The hybrid method is a probability-weighed expected return method, or PWERM,
where the equity value in one or more of the scenarios is allocated using an OPM. The OPM treats common stock and preferred stock as call options on the
total  equity  value  of  a  company,  with  exercise  prices  based  on  the  value  thresholds  at  which  the  allocation  among  the  various  holders  of  a  company’s
securities  changes.  Under  this  method,  the  common  stock  has  value  only  if  the  funds  available  for  distribution  to  stockholders  exceed  the  value  of  the
preferred stock liquidation preferences at the time of a liquidity event, such as a strategic sale or merger. The PWERM is a scenario-based methodology that
estimates the fair value of common stock based upon an analysis of future values for the company, assuming various outcomes. The common stock value is
based  on  the  probability-weighted  present  value  of  expected  future  investment  returns  considering  each  of  the  possible  outcomes  available  as  well  as  the
rights  of  each  class  of  stock.  The  future  value  of  the  common  stock  under  each  outcome  is  discounted  back  to  the  valuation  date  at  an  appropriate  risk-
adjusted discount rate and probability weighted to arrive at an indication of value for the common stock.

Stock-Based Award Grants in Connection with and Following Our Initial Public Offering

Our board of directors approved, effective upon the commencement of trading of our common stock on the Nasdaq Global Select Market, grants of
options to purchase an aggregate of 625,000 shares of common stock, with an exercise price per share equal to the estimated fair market value of our common
stock on such date of grant, which our board of directors determined to be equal to the initial public offering price of our common stock, to certain of our
employees and restricted stock units for an aggregate of 34,614 shares of common stock to one of our non-employee directors.

Following our initial public offering, the exercise price per share of stock-based award grants will be set at the closing price of our common stock on

the Nasdaq Global Select Market on the applicable date of grant, which our board of directors believes represents the fair value of our common stock.

Emerging Growth Company Status

The Jumpstart Our Business Startups Act of 2012, or the JOBS Act, provides that an “emerging growth company” can take advantage of the extended
transition period afforded by the JOBS Act for the implementation of new or revised accounting standards. However, we have elected not to “opt out” of such
extended transition period, which means that when a standard is issued or revised and it has different application dates for public or private companies, we
will adopt the new or revised standard at the time private companies adopt the new or revised standard, provided that we continue to be an emerging growth
company.  The  JOBS  Act  provides  that  our  decision  to  take  advantage  of  the  extended  transition  period  for  complying  with  new  or  revised  accounting
standards is irrevocable.

Off-Balance Sheet Arrangements

As of December 31, 2018, 2017 and 2016, we did not have any off-balance sheet arrangements, as defined in Item 303(a)(4)(ii) of Regulation S-K,

such as the use of unconsolidated subsidiaries, structured finance, special purpose entities or variable interest entities.

Recent Accounting Pronouncements

Refer to the “Summary of Significant Accounting Policies” footnote within our consolidated financial statements included elsewhere in this Annual

Report on Form 10-K for our analysis of recent accounting pronouncements that are applicable to our business.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk.

Market risk is the risk of loss to future earnings, values or future cash flows that may result from changes in the price of a financial instrument. The
value of a financial instrument may change as a result of changes in interest rates, exchange rates, commodity prices, equity prices and other market changes.
We are exposed to market risk related to changes in foreign currency exchange rates and interest rates. We do not use derivative financial instruments for
speculative or trading purposes. However, we have entered into, and in the future expect to continue to enter into, exchange rate hedging arrangements to
manage certain of the risks described below.

Foreign Currency Exchange Risk

We have accounts receivables denominated in foreign currencies, and our operations outside of the United States incur their operating expenses in
foreign currencies. To date, the majority of our product sales and inventory purchases have been denominated in U.S. dollars. For our subsidiary in Ireland,
the U.S. dollar is the functional currency. For each of our other foreign subsidiaries, the functional currency is the local currency. During the years ended
December 31, 2018, 2017 and 2016, we incurred foreign currency transaction gains (losses) of $(0.9) million, $0.9 million and $(0.3) million, respectively,
primarily  related  to  unrealized  and  realized  foreign  currency  gains  (losses)  for  accounts  receivables  denominated  in  foreign  currencies.  These  foreign
currency  transaction  gains  (losses)  were  recorded  as  a  component  of  other  income  (expense),  net  in  our  consolidated  statements  of  operations  and
comprehensive income. We believe that a 5% change in the exchange rate between the U.S. dollar and euro would not materially impact our operating results
or  financial  position.  We  entered  into  foreign  currency  exchange  contracts  during  the  year  ended  December  31,  2018  that  mature  in  the  second  and  third
quarters of 2019, and we expect to continue to hedge certain significant transactions denominated in currencies other than the U.S. dollar in the future.

Interest Rate Sensitivity

Our cash and cash equivalents as of December 31, 2018 consisted of cash maintained in FDIC-insured operating accounts as well as investments in
money  market  mutual  funds  and  certificates  of  deposit.  We  also  have  policies  requiring  us  to  invest  in  high-quality  issuers,  limit  our  exposure  to  any
individual issuer, and ensure adequate liquidity. Our primary exposure to market risk for our cash and cash equivalents is interest income sensitivity, which is
primarily affected by changes in the general level of U.S. interest rates. However, we do not believe a sudden change in the interest rates for our cash and cash
equivalents would have a material impact on our financial condition, results of operations or cash flows.

67

We  have  a  credit  agreement  that  provides  us  with  a  term  loan  facility  of  $300.0  million  and  a  revolving  credit  facility  of  up  to  $25.0  million  in
revolving  credit  loans  and  letters  of  credit.  Borrowings  under  the  facilities  bear  interest  at  a  floating  rate,  which  can  be  either  a  Eurodollar  rate  plus  an
applicable margin or, at our option, a base rate (defined as the highest of (x) the JPMorgan Chase, N.A. prime rate, (y) the federal funds effective rate, plus
one-half  percent  (0.50%)  per  annum  and  (z)  a  one-month  Eurodollar  rate  plus  1.00%  per  annum)  plus  an  applicable  margin.  The  applicable  margin  for
borrowings under the term loan facility is 4.00% per annum for Eurodollar rate loans (subject to a 1.00% per annum interest rate floor) and 3.00% per annum
for base rate loans. As a result of the completion of our initial public offering in December 2017, the applicable margin for borrowings under the revolving
credit  facility  is  1.75%  per  annum  for  Eurodollar  rate  loans  and  0.75%  per  annum  for  base  rate  loans,  subject  to  reduction  based  on  our  maintaining  of
specified net leverage ratios.

As  of  December  31,  2018,  we  had  borrowings  of  $294.0  million  outstanding  under  the  term  loan  facility,  bearing  interest  at  a  rate  of  6.52%  per
annum,  which  was  based  on  a  one-month  Eurodollar  rate  of  2.52%  per  annum  plus  the  applicable  margin  of  4.00%  per  annum  for  Eurodollar  rate  loans.
Changes  in  interest  rates  could  cause  interest  charges  on  our  term  loan  facility  to  fluctuate.  Based  on  the  amount  of  borrowings  outstanding  as  of
December 31, 2018, an increase of 10%, or approximately 25 basis points, in the one-month Eurodollar rate as of December 31, 2018 would cause pre-tax
decreases to our earnings and cash flows of approximately $0.7 million per year, assuming that such rate were to remain in effect for a year. A decrease of
10%, or approximately 25 basis points, in the one-month Eurodollar rate as of December 31, 2018 would cause pre-tax increases to our earnings and cash
flows of approximately $0.7 million, assuming that such rate were to remain in effect for a year.

As of December 31, 2018, we were not exposed to interest rate risk under the revolving credit facility as a result of having no outstanding borrowings

under the facility.

Inflation Risk

We do not believe that inflation has had a material effect on our business. However, if global demand for the base materials utilized in our suppliers’
components were to significantly increase for the components we purchase from our suppliers to manufacture our products, our costs could become subject to
significant inflationary pressures, and we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm
our business, operating results and financial condition.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Stockholders of Casa Systems, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Casa Systems, Inc. and its subsidiaries (the “Company”) as of December 31, 2018 and
2017, and the related consolidated statements of operations and comprehensive income, of convertible preferred stock and stockholders’ equity (deficit), and
of cash flows for each of the three years in the period ended December 31, 2018, including the related notes (collectively referred to as the “consolidated
financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of
December  31,  2018  and  2017,  and  the  results  of  its  operations  and  its  cash  flows  for  each  of  the  three  years  in  the  period  ended  December  31,  2018  in
conformity with accounting principles generally accepted in the United States of America.

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 of these consolidated financial statements 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 consolidated financial statements are free of material misstatement, whether due to error
or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits
we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of
the Company's internal control over financial reporting. Accordingly, we express no such opinion.

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.

CASA SYSTEMS, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
(Amounts in thousands, except per share amounts)

1. Nature of Business and Basis of Presentation

Casa  Systems,  Inc.  (the  “Company”)  was  incorporated  under  the  laws  of  the  State  of  Delaware  on  February  28,  2003.  The  Company  is  a  global
communications technology company headquartered in Andover, Massachusetts and has wholly owned subsidiaries in China, France, Canada, Ireland, Spain,
Colombia and the Netherlands.

The Company offers solutions for next-generation centralized, distributed and virtualized architectures for cable broadband, fixed-line broadband and
wireless networks. The Company’s solutions enable customers to cost-effectively and dynamically increase network speed, add bandwidth capacity and new
services for consumers and enterprises, reduce network complexity and reduce operating and capital expenditures.

The Company is subject to a number of risks similar to other companies of comparable size and other companies selling and providing services to the
communications  industry.  These  risks  include,  but  are  not  limited  to,  the  level  of  capital  spending  by  the  communications  industry,  a  lengthy  sales  cycle,
dependence on the development of new products and services, unfavorable economic and market conditions, competition from larger and more established
companies,  limited  management  resources,  dependence  on  a  limited  number  of  contract  manufacturers  and  suppliers,  the  rapidly  changing  nature  of  the
technology used by the communications industry and reliance on resellers and sales agents. Failure by the Company to anticipate or to respond adequately to
technological developments in its industry, changes in customer or supplier requirements, changes in regulatory requirements or industry standards, or any
significant delays in the development or introduction of products could have a material adverse effect on the Company’s operating results, financial condition
and cash flows.

In December 2017, the Company closed its initial public offering (“IPO”) of 6,900 shares of its common stock at an offering price of $13.00 per share,
including 900 shares pursuant to the underwriters’ option to purchase additional shares of the Company’s common stock. The Company received net proceeds
of $79,327, after deducting underwriting discounts and commissions of $6,279 and offering costs of $4,094. Upon the closing of the IPO, all 4,038 shares of
the Company’s then-outstanding preferred stock automatically converted on a ten-for-one basis into an aggregate of 40,382 shares of the Company’s common
stock.  Upon conversion of the preferred stock, the Company reclassified $97,439 from temporary equity to additional paid-in capital and $40 from temporary
equity to common stock.

On April 30, 2018, the Company closed its follow-on public offering in which certain stockholders sold 7,350 shares of the Company’s common stock
at a price of $25.00 per share, before deducting underwriting discounts and commissions (the “follow-on offering”). The Company did not sell any common
stock  in  the  follow-on  offering  and  did  not  receive  any  of  the  proceeds  from  the  sale  of  the  Company’s  common  stock  by  the  selling  stockholders.  In
connection with the sale of the Company’s common stock in the follow-on offering, certain of the selling stockholders disgorged $3,770 of profits recognized
from the sale, after deducting $41 of offering costs, to the Company in accordance with Section 16(b) of the Securities Exchange Act of 1934, as amended,
which was recorded as an increase in additional paid-in capital. The Company incurred $856 of transaction costs in connection with the follow-on offering, of
which $815 was recorded in general and administrative expenses in the accompanying consolidated statements of operations.

The Company is an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and may remain
an emerging growth company until the last day of the fiscal year following the fifth anniversary of the initial public offering, subject to specified conditions.
The  JOBS  Act  provides  that  an  emerging  growth  company  can  take  advantage  of  the  extended  transition  period  afforded  by  the  JOBS  Act  for  the
implementation of new or revised accounting standards. The Company has elected not to “opt out” of such extended transition period, which means that when
a standard is issued or revised and it has different application dates for public or private companies, the Company will adopt the new or revised standard at the
time private companies adopt the new or revised standard, provided that the Company continues to be an emerging growth company. The JOBS Act provides
that the decision to take advantage of the extended transition period for complying with new or revised accounting standards is irrevocable.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United
States  of  America  (“GAAP”)  and  include  the  accounts  and  results  of  operations  of  the  Company  and  its  wholly  owned  subsidiaries.  All  intercompany
transactions and balances have been eliminated in consolidation.

75

2. Summary of Significant Accounting Policies

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and the disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of
revenue and expenses during the reporting periods.

Significant  estimates  and  judgments  relied  upon  by  management  in  preparing  these  consolidated  financial  statements  include  revenue  recognition,
provision  for  doubtful  accounts,  reserves  for  excess  and  obsolete  inventory,  valuation  of  inventory  and  deferred  inventory  costs,  the  expensing  and
capitalization of software-related research and development costs, amortization and depreciation periods, recoverability of net deferred tax assets, valuations
of uncertain tax positions, provision for income taxes, warranty allowances, the valuation of the Company’s common stock and other equity instruments, and
stock-based compensation expense.

Although the Company regularly reassesses the assumptions underlying these estimates, actual results could differ materially from these estimates.
Changes in estimates are recorded in the period in which they become known. The Company bases its estimates on historical experience and various other
assumptions that it believes to be reasonable under the circumstances existing at the time such estimates are made.

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents include all highly liquid investments maturing within three months from the date of purchase. As of December 31, 2018

and 2017, the Company’s cash and cash equivalents consisted of investments in certificates of deposit, commercial paper and money market mutual funds.

Restricted cash, which was included in other assets as of December 31, 2018, consisted of a certificate of deposit of $1,000 pledged as collateral for a

stand-by letter of credit required to support a contractual obligation. The Company did not have any restricted cash as of December 31, 2017.

The following table is a reconciliation of cash, cash equivalents and restricted cash included in the accompanying consolidated balance sheets that

sum to the total cash, cash equivalents and restricted cash included in the accompanying consolidated statements of cash flows.

Accounts receivable are presented net of a provision for doubtful accounts, which is an estimate of amounts that may not be collectible. Accounts
receivable  for  arrangements  with  customary  payment  terms,  which  are  one  year  or  less,  are  recorded  at  invoiced  amounts  and  do  not  bear  interest.  The
Company generally does not require collateral, but the Company may, in certain instances based on its credit assessment, require full or partial prepayment
prior to shipment.

For  certain  customers  and/or  for  certain  transactions,  the  Company  provides  extended  payment  arrangements  to  allow  the  customer  to  pay  for  the
purchased equipment in monthly, other periodic or lump-sum payments over a period of one to five years. Certain of these arrangements are collateralized by
the underlying assets during the term of the arrangement. Payments due beyond 12 months from the balance sheet date are recorded as non-current assets. In
addition,  amounts  recorded  as  current  and  non-current  accounts  receivable  for  extended  payment  term  arrangements  at  any  balance  sheet  date  have  a
corresponding amount recorded as deferred revenue because the Company defers the recognition of revenue for all extended payment term arrangements and
only recognizes revenue to the extent of the payment amounts that become due from the customer.

Although there is no contractual interest rate for customer arrangements with extended payment terms, the Company imputes interest on the accounts
receivable related to these arrangements and reduces the arrangement fee that will be recognized as revenue for the amount of the imputed interest, which is
recorded as interest income over the payment term using the effective interest method. For the periods presented in the accompanying consolidated financial
statements, the impact of imputing interest on revenue and interest income was insignificant.

The Company performs ongoing credit evaluations of its customers and, if necessary, provides a provision for doubtful accounts and expected losses.
When  assessing  and  recording  its  provision  for  doubtful  accounts,  the  Company  evaluates  the  age  of  its  accounts  receivable,  current  economic  trends,
creditworthiness  of  the  customers,  customer  payment  history,  and  other  specific  customer  and  transaction  information.  The  Company  writes  off  accounts
receivable against the provision when it determines a balance is uncollectible and no longer actively pursues collection of the receivable. Adjustments to the
provision for doubtful accounts are recorded as general and administrative expenses in the consolidated statements of operations and comprehensive income.
A summary of changes in the provision for doubtful accounts for the years ended December 31, 2018, 2017 and 2016 is as follows:

As of December 31, 2018 and 2017, the Company concluded that all amounts due under extended payment term arrangements were collectible and no
reserve for credit losses was recorded. During the years ended December 31, 2018, 2017 and 2016, the Company did not provide a reserve for credit losses
and did not write off any uncollectible receivables due under extended payment term arrangements.

Inventories

Inventories  are  valued  at  the  lower  of  cost  or  market  value.  Cost  is  computed  using  the  first-in  first-out  convention.  Inventories  are  composed  of
hardware and related component parts of finished goods. The Company establishes provisions for excess and obsolete inventories after evaluating historical
sales, future demand, market conditions, expected product life cycles, and current inventory levels to reduce such inventories to their estimated net realizable
value.  Such  provisions  are  made  in  the  normal  course  of  business  and  charged  to  cost  of  revenue  in  the  consolidated  statements  of  operations  and
comprehensive income.

Deferred inventory costs are included within inventory in the consolidated balance sheets. Deferred inventory costs represent the cost of products that
have  been  delivered  to  the  customer  for  which  revenue  associated  with  the  arrangement  has  been  deferred  as  a  result  of  not  meeting  all  of  the  required
revenue recognition criteria, such as receipt of customer acceptance. Until the revenue recognition criteria are met, the Company retains the right to a return
of  the  underlying  inventory.  Deferred  inventory  costs  are  recognized  as  cost  of  revenue  in  the  consolidated  statements  of  operations  and  comprehensive
income when the related revenue is recognized.

Property and Equipment

Property and equipment is stated at historical cost less accumulated depreciation. Depreciation is computed using the straight-line method over the
estimated useful lives of the assets. Leasehold improvements are recorded at cost with any reimbursement from the landlord being accounted for as deferred
rent, which is amortized using the straight-line method over the lease term. Costs for trial systems held and used by the Company’s customers pursuant to
evaluation agreements are also included within property and equipment. Trial systems held and used by the Company’s customers are depreciated over the
estimated useful life of such assets, which is two years.

Whenever  a  trial  system  is  sold  to  a  customer  and  the  selling  price  is  recorded  as  revenue,  the  related  net  book  value  of  the  trial  system  sold  is

removed from property and equipment and recorded as a cost of revenue. Maintenance and repairs expenditures are charged to expense as incurred.

Estimated useful lives of the respective property and equipment assets are as follows:

Computers and purchased software
Leasehold improvements
Furniture and fixtures
Machinery and equipment
Building
Building improvements
Trial systems at customers’ sites

Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation are removed from the accounts and any resulting gain

or loss is included in income from operations.

Impairment of Long-Lived Assets

The  Company  evaluates  its  long-lived  assets,  which  consist  primarily  of  property  and  equipment,  for  impairment  whenever  events  or  changes  in
circumstances indicate that the carrying amount of such assets may not be recoverable. Factors that the Company considers in deciding when to perform an
impairment  review  include  significant  underperformance  of  the  business  in  relation  to  expectations,  significant  negative  industry  or  economic  trends  and
significant changes or planned changes in the use of the assets. Recoverability of assets to be held and used is measured by a comparison of the carrying
amount  of  an  asset  to  the  future  undiscounted  net  cash  flows  expected  to  be  generated  by  the  asset.  If  such  assets  are  considered  to  be  impaired,  the
impairment to be recognized is measured by the amount by which the carrying amount of the asset exceeds the fair value of the asset, less the cost to sell. No
events or changes in circumstances existed to require an impairment assessment during the years ended December 31, 2018, 2017 and 2016.  

Deferred Offering Costs

Deferred  offering  costs  of  $4,094,  consisting  of  legal,  professional  accounting  and  other  third-party  fees  related  to  the  IPO,  were  reclassified  to
additional paid-in capital as a reduction of the proceeds upon the closing of the IPO in December 2017. Deferred offering costs of $1,148 and $2,384 were
paid during the years ended December 31, 2018 and 2017, respectively.

Concentration of Risks

Financial  instruments  that  potentially  subject  the  Company  to  concentrations  of  credit  risk  consist  principally  of  cash  and  cash  equivalents  and
accounts receivable. Cash and cash equivalents consist of demand deposits, savings accounts, commercial paper, money market mutual funds, and certificates
of deposit with financial institutions, which may exceed Federal Deposit Insurance Corporation limits. The Company has not experienced any losses related
to its cash and cash equivalents and does not believe that it is subject to unusual credit risk beyond the normal credit risk associated with commercial banking
relationships.

Customer B was a related party, Liberty Global Affiliates (see Note 15).

Certain of the components and subassemblies included in the Company’s products are obtained from a single source or a limited group of suppliers. In
addition,  the  Company  primarily  relies  on  two  third  parties  to  manufacture  certain  components  of  its  products.  Although  the  Company  seeks  to  reduce
dependence on those limited sources of suppliers and manufacturers, the partial or complete loss of certain of these sources could have a material adverse
effect on the Company’s operating results, financial condition and cash flows and damage its customer relationships.

Product Warranties

Substantially all of the Company’s products are covered by a warranty for software and hardware for periods ranging from 90 days to one year. In
addition, in conjunction with customers’ renewals of maintenance and support contracts, the Company offers an extended warranty for periods typically of
one to three years for agreed-upon fees. In the event of a failure of a hardware product or software covered by these warranties, the Company must repair or
replace  the  software  or  hardware  or,  if  those  remedies  are  insufficient,  and  at  the  discretion  of  the  Company,  provide  a  refund.  The  Company’s  warranty
reserve, which is included in accrued expenses and other current liabilities in the consolidated balance sheets, reflects estimated material, labor and other costs
related  to  potential  or  actual  software  and  hardware  warranty  claims  for  which  the  Company  expects  to  incur  an  obligation.  The  Company’s  estimates  of
anticipated  rates  of  warranty  claims  and  the  costs  associated  therewith  are  primarily  based  on  historical  information  and  future  forecasts.  The  Company
periodically assesses the adequacy of the warranty reserve and adjusts the amount as necessary. If the historical data used to calculate the adequacy of the
warranty reserve are not indicative of future requirements, additional or reduced warranty reserves may be required.

A summary of changes in the amount reserved for warranty costs for the years ended December 31, 2018, 2017 and 2016 is as follows:

The Company generates revenue from sales of its broadband products, along with associated maintenance and support services, and, to a lesser extent,
from sales of professional services and extended warranty services. The Company also generates revenue from sales of additional line cards and software-
based capacity expansions. Maintenance and support services include telephone support and unspecified software upgrades and updates provided on a when-
and-if-available basis.

In  the  Company’s  consolidated  statements  of  operations  and  comprehensive  income,  revenue  from  sales  of  broadband  products  and  capacity
expansions is classified as product revenue, and revenue from maintenance and support, professional services and extended warranty services is classified as
service revenue.

The Company recognizes revenue from sales when the following revenue recognition criteria are met:

•

•

•

Persuasive evidence of an arrangement exists. Binding contracts and/or customer purchase orders are generally evidence of an arrangement.
For  professional  services,  evidence  of  an  arrangement  may  also  include  information  documenting  the  scope  of  work  to  be  performed,  and
customer acceptance terms, if any.

Delivery has occurred. For broadband products, shipping documents and customer acceptance, if applicable, verify that delivery has occurred.
For  software-enabled  capacity  expansions,  delivery  occurs  when  the  additional  bandwidth  capacity  is  made  available  to  the  customer.  For
professional services, delivery occurs as the services are completed.

The sales price is fixed or determinable. The sales price is considered fixed or determinable when the fees have been contractually agreed with
the customer and are not deemed to be subject to refund, adjustment or future discounts, and when the payment terms of the transaction do not
extend beyond the Company’s customary payment terms, which are one year or less.

Collectibility  is  reasonably  assured.  The  Company  assesses  the  ability  to  collect  from  its  customers  based  on  a  number  of  factors  that
generally include information supplied by credit agencies, references and/or analysis of customer accounts and payment history. If collection
from a customer is not considered reasonably assured, all revenue related to the customer arrangement is deferred until payment is received
and all other revenue recognition criteria have been met.

When customer acceptance of the product is required and is other than perfunctory, revenue for the entire customer arrangement is deferred until the

acceptance has been received.

The Company’s products have both software and non-software (i.e., hardware) components that function together to deliver the products’ essential
functionality. In addition, the hardware sold generally cannot be used apart from the embedded software. As a result, all of the Company’s product and service
offerings are excluded from the scope of software revenue recognition requirements and instead fall within the scope of Accounting Standards Codification
(“ASC”) Topic 605, Revenue Recognition.

Many of the Company’s sales involve multiple-deliverable arrangements that include products and maintenance and support services and, on a limited
basis,  may  also  include  professional  services  and  extended  warranty  services.  The  Company  has  determined  that  its  products,  maintenance  and  support
services, professional services and extended warranty services have standalone value to the customer because each of these deliverables is sold separately by
the  Company  to  its  customers  or,  in  the  case  of  professional  services,  is  sold  separately  by  other  vendors.  As  a  result,  the  Company  treats  each  of  these
deliverables as a separate unit of accounting for purposes of allocating the arrangement fee and recognizing the revenue of each unit.

For its multiple-deliverable arrangements, the Company allocates the arrangement fee to each deliverable based on the relative selling prices of each
of the deliverables in the arrangement using the selling price hierarchy. In such circumstances, the Company determines the selling price of each deliverable
based on vendor-specific objective evidence (“VSOE”) of selling price, if it exists; otherwise, third-party evidence (“TPE”) of selling price. If neither VSOE
nor TPE exists, the Company uses its best estimate of the selling price (“BESP”) for the deliverable. The Company limits the amount of the arrangement fee
allocated to deliverables to the amount that is not contingent on the future delivery of products or services or future performance obligations and the amount
that is not subject to customer-specific return or refund privileges.

To  date,  the  Company  has  not  been  able  to  establish  VSOE  of  selling  price  of  any  of  its  products,  maintenance  and  support  services,  professional
services or extended warranty services because the Company has not established a history of consistently pricing each product or service within a narrow
range. In addition, the Company is not able to determine TPE of selling price for its products or services because the Company’s various product and service
offerings  contain  a  significant  level  of  differentiation  and,  therefore,  comparable  pricing  of  competitors’  products  and  services  with  similar  functionality
cannot be obtained. As the Company is unable to establish selling price using VSOE or TPE, the Company uses BESP to allocate the arrangement fee to
products,  maintenance  and  support  services,  professional  services  and  extended  warranty  services  in  multiple-deliverable  arrangements.  The  objective  of
BESP is to determine the price at which the Company would transact a sale if a product or service was sold on a standalone basis. The Company determines
BESP of selling price for its products and services by considering multiple factors, including, but not limited to, its historical pricing practices by customer
type and geographic-specific market factors.

Revenue from product sales is recognized upon delivery to the customer, or upon the later receipt of customer acceptance of the product when such

acceptance is required.

Revenue from maintenance and support services is recognized ratably over the contract period, which is typically one year, but can be as long as three
or five years. When customer acceptance of a product is required, the recognition of any associated maintenance and support services revenue commences
only upon customer acceptance of the associated product. Revenue from extended warranty services is recognized ratably over the contract period, which is
typically one to three years.

Revenue from professional services is recognized as the services are performed. Professional services generally include installation or configuration
services  that  are  not  deemed  to  be  essential  to  the  functionality  of  the  products.  When  customer  acceptance  is  required,  the  recognition  of  any  associated
professional services revenue is deferred until the associated product and/or professional service is accepted by the customer.

80

 
 
Resellers

The  Company  markets  and  sell  its  products  through  its  direct  global  sales  force,  supported  by  sales  agents,  and  through  resellers.  The  Company’s
resellers receive an order from an end customer prior to placing an order with the Company, and the Company confirms the identification of or is aware of the
end customer prior to accepting such order. The Company invoices the reseller an amount that reflects a reseller discount and records revenue based on the
amount of the discounted arrangement fee. The Company’s resellers do not stock inventory received from the Company.

When the Company transacts with a reseller, its contractual arrangement is with the reseller and not with the end customer. Whether the Company
transacts business with and receives the order from a reseller or directly from an end customer, its revenue recognition policy and resulting pattern of revenue
recognition for the order are the same.

The Company also uses sales agents that assist in the sales process with certain customers primarily located in the Latin America and Asia-Pacific
regions. Sales agents are not resellers. If a sales agent is engaged in the sales process, the Company receives the order directly from and sells the products and
services directly to the end customer, and the Company pays a commission to the sales agent, calculated as a percentage of the related customer payment.
Sales  agent  commissions  are  recorded  as  expenses  when  incurred  and  are  classified  as  sales  and  marketing  expenses  in  the  Company’s  consolidated
statements of operations and comprehensive income.

Deferred Revenue

Amounts billed in excess of revenue recognized are recorded as deferred revenue. Deferred revenue includes customer deposits, amounts billed for
maintenance and support services contracts in advance of services being performed, amounts for trade-in right liabilities and amounts related to arrangements
that have been deferred as a result of not meeting the required revenue recognition criteria as of the end of the reporting period. Deferred revenue expected to
be recognized as revenue more than one year subsequent to the balance sheet date is reported within long-term liabilities in the consolidated balance sheets.

When  the  payment  terms  of  a  customer  order  extend  beyond  the  Company’s  customary  payment  terms,  which  are  one  year  or  less,  the  Company
considers the arrangement to be an extended payment term arrangement and concludes that the sales price is not fixed or determinable for revenue recognition
purposes. In these circumstances, the Company defers all revenue of the arrangement and only recognizes revenue to the extent of the payment amounts that
become due, provided that all other revenue recognition criteria have been met.

The Company defers recognition of incremental direct costs, such as cost of goods and services, until recognition of the related revenue. Such costs
are classified as current assets if the related deferred revenue is classified as current, and such costs are classified as non-current assets if the related deferred
revenue is classified as non-current.

Other Revenue Recognition Policies

In  limited  instances,  the  Company  has  offered  future  rebates  to  customers  based  on  a  fixed  or  variable  percentage  of  actual  sales  volumes  over
specified periods. The future rebates earned based on the customer’s purchasing from the Company in one period may be used as credits to be applied by
them against accounts receivable due to the Company in later periods. The Company accounts for these future rebates as a reduction of the revenue recorded
for the customer’s current purchasing activity giving rise to the future rebates. The liability for these future rebates is recorded as accrued customer incentives
(within accrued expenses and other current liabilities) until the credits have been applied by the customer against accounts receivable due to the Company or
the credits expire.

When  future  trade-in  rights  are  granted  to  customers  at  the  time  of  sale,  the  Company  defers  a  portion  of  the  revenue  recognized  for  the  sale  and
accounts  for  it  as  a  guarantee  at  fair  value  until  the  trade-in  right  is  exercised  or  the  right  expires,  in  accordance  with  ASC  Topic  460,  Guarantees.
Determining the fair value of the trade-in right requires the Company to estimate the probability of the trade-in right being exercised and the future value of
the product upon trade-in. The Company assesses and updates these estimates each reporting period, and updates to these estimates may result in either an
increase or decrease in the amount of revenue deferred. As of December 31, 2018 and 2017, no amounts for trade-in rights were deferred.

Billings to customers for shipping costs and reimbursement of out-of-pocket expenses, including travel, lodging and meals, are recorded as revenue,

and the associated costs incurred by the Company for those items are recorded as cost of revenue.

81

 
The Company excludes any taxes assessed by a governmental authority that are directly imposed on a revenue-producing transaction (e.g., sales, use

and value added taxes) from its revenue and costs.

Stock-Based Compensation

The Company measures stock options and other stock-based awards granted to employees and directors based on the fair value on the date of the grant
and recognizes compensation expense of those awards, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of
the respective award. Generally, the Company issues stock options with only service-based vesting conditions and records the expense for these awards using
the straight-line method.

For stock-based awards granted to non-employee consultants, compensation expense is recognized over the period during which services are rendered
by such non-employee consultants until completed. At the end of each financial reporting period prior to completion of the service, the fair value of these
awards is remeasured using the then-current fair value of the Company’s common stock and updated assumption inputs in the Black-Scholes option-pricing
model.

The  Company  classifies  stock-based  compensation  expense  in  its  consolidated  statements  of  operations  and  comprehensive  income  in  the  same

manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

The Company recognizes compensation expense for only the portion of awards that are expected to vest. In developing a forfeiture rate estimate, the
Company has considered its historical experience to estimate pre-vesting forfeitures for service-based awards. The impact of a forfeiture rate adjustment will
be recognized in full in the period of adjustment, and if the actual forfeiture rate is materially different from the Company’s estimate, the Company may be
required to record adjustments to stock-based compensation expense in future periods.

The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option pricing model. The Company was a private
company until December 14, 2017 and lacks sufficient company-specific historical and implied volatility information for its stock. Therefore, it estimates its
expected stock volatility based on the historical volatility of publicly traded peer companies and expects to continue to do so until such time as it has adequate
historical  data  regarding  the  volatility  of  its  own  traded  stock  price.  The  expected  term  of  the  Company’s  stock  options  has  been  determined  utilizing  the
“simplified”  method  for  awards  that  qualify  as  “plain-vanilla”  options.  The  expected  term  of  stock  options  granted  to  non-employees  is  equal  to  the
contractual term of the option award. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the
award for time periods approximately equal to the expected term of the award. Expected dividend yield is based on the fact that the Company does not have a
history of declaring or paying cash dividends, except for the special cash dividends declared in November 2014, June 2016, December 2016, May 2017 and
November  2017  and  in  those  circumstances  the  board  of  directors  approved  cash  dividends  to  be  paid  to  holders  of  the  Company’s  stock  options,  stock
appreciation rights (“SARs”) and restricted stock units (“RSUs”) upon vesting as an equitable adjustment to the holders of such instruments.

The Company has also granted SARs to certain employees, which require the Company to pay in cash upon exercise an amount equal to the product
of the excess of the per share fair market value of the Company’s common stock on the date of exercise over the exercise price, multiplied by the number of
shares of common stock with respect to which the SAR is exercised. Because these awards may require the Company to settle the awards in cash, they are
accounted for as a liability in the Company’s consolidated balance sheets. The liability related to these awards, as well as related compensation expense, is
recognized over the period during which services are rendered until completed. Changes in the fair value of the SAR liability are estimated using the Black-
Scholes  option  pricing  model  and  are  recorded  in  the  consolidated  statements  of  operations  and  comprehensive  income.  After  vesting  is  completed,  the
Company will continue to remeasure the fair market value of the liability until the award is either exercised or canceled, with changes in the fair value of the
liability recorded in the consolidated statements of operations and comprehensive income.

Research and Development Costs

The Company expenses research and development costs as incurred. Costs incurred to develop software to be licensed to customers are expensed prior
to the establishment of technological feasibility of the software and are capitalized thereafter until commercial release of the software. The Company has not
historically capitalized software development costs as the establishment of technological feasibility typically occurs shortly before the commercial release of
its software, which is embedded in its products. As such, all software development costs related to software for license to customers are expensed as incurred
and included within research and development expense in the accompanying consolidated statements of operations and comprehensive income.

82

 
Advertising Costs

Advertising  costs  are  expensed  as  incurred  and  are  included  in  selling  and  marketing  expense  in  the  accompanying  consolidated  statements  of

operations and comprehensive income. Advertising expenses were not significant for any periods presented.

Foreign Currency Translation

For  the  Company’s  subsidiary  in  Ireland,  the  U.S.  dollar  is  the  functional  currency.  For  each  of  the  Company’s  other  foreign  subsidiaries,  the
functional currency is its local currency. Assets and liabilities of these foreign subsidiaries are translated into U.S. dollars using period-end exchange rates,
and revenues and expenses are translated into U.S. dollars using average exchange rates in effect during each period. The effects of these foreign currency
translation adjustments are included in accumulated other comprehensive income, a separate component of stockholders’ equity (deficit).

Foreign currency transaction gains (losses) are included in the consolidated statements of operations and comprehensive income as a component of

other income (expense) and totaled $(911), $886 and $(328) for the years ended December 31, 2018, 2017 and 2016, respectively.

Fair Value Measurements

Certain assets and liabilities are carried at fair value under GAAP. Fair value is defined as the price that would be received for an asset or the exit price
that  would  be  paid  to  transfer  a  liability  in  the  principal  or  most  advantageous  market  in  an  orderly  transaction  between  market  participants  on  the
measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs.
Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which
the first two are considered observable and the last is considered unobservable:

Level 1—

Quoted prices in active markets for identical assets and liabilities.

Level 2—

Observable  inputs  (other  than  Level  1  quoted  prices),  such  as  quoted  prices  in  active  markets  for  similar  assets  or  liabilities  at  the
measurement date; quoted prices in markets that are not active for identical or similar assets and liabilities; or other inputs that are observable
or can be corroborated by observable market data.

Level 3—

Unobservable  inputs  that  involve  management  judgment  and  are  supported  by  little  or  no  market  activity,  including  pricing  models,
discounted cash flow methodologies and similar techniques.

The categorization of a financial instrument within the valuation hierarchy is based on the lowest level of input that is significant to the fair value

measurement.

The Company’s cash equivalents, marketable securities, foreign currency forward contracts and SARs are carried at fair value, determined according
to the fair value hierarchy described above (see Note 6). The fair values of accounts receivable, accounts payable and accrued expenses and other current
liabilities approximate their fair values due to the short-term nature of these assets and liabilities, with the exception of amounts recorded by the Company as
“accounts  receivable,  non-current,”  which  represent  amounts  billed  to  customers  for  which  payment  has  not  yet  become  due  and  for  which  an  offsetting
amount  of  deferred  revenue  has  been  recorded.  The  carrying  values  of  the  Company’s  debt  obligations  (see  Note  9)  as  of  December  31,  2018  and  2017
approximated their fair values because the debt bears interest at rates the Company would be required to pay on the issuance of debt with similar terms, based
on an analysis of recent market conditions and other Company-specific factors.

Income Taxes

The Company accounts for income taxes using the asset and liability method, which requires the recognition of deferred tax assets and liabilities for
the expected future tax consequences of temporary differences between the financial statement and tax basis of assets and liabilities, as measured by enacted
tax  rates  anticipated  to  be  in  effect  when  these  differences  reverse.  This  method  also  requires  the  recognition  of  future  tax  benefits  to  the  extent  that
realization  of  such  benefits  is  more  likely  than  not.  Deferred  tax  expense  or  benefit  is  the  result  of  changes  in  the  deferred  tax  assets  and  liabilities.  The
Company assesses the likelihood that its deferred tax assets will be recovered from future taxable income and, to the extent it believes, based upon the weight
of available evidence, that it is more likely than not that all or a portion of the deferred tax assets will not be realized, a valuation allowance is established
through  a  charge  to  income  tax  expense.  Potential  for  recovery  of  deferred  tax  assets  is  evaluated  by  estimating  the  future  taxable  profits  expected  and
considering prudent and feasible tax planning strategies.

83

 
 
 
 
 
 
The Company records a liability for potential payments of taxes to various tax authorities related to uncertain tax positions and other tax matters. The
recorded liability is based on a determination of whether and how much of a tax benefit taken by the Company in its tax filings or positions is “more likely
than  not”  to  be  realized.  The  amount  of  the  benefit  that  may  be  recognized  in  the  financial  statements  is  the  largest  amount  that  has  a  greater  than  50%
likelihood of being realized upon ultimate settlement. To the extent that the assessment of such tax positions changes, the change in estimate is recorded in the
period in which the determination is made. The Company establishes a liability, which is included in accrued income taxes in the consolidated balance sheets,
for tax-related uncertainties based on estimates of whether, and the extent to which, additional taxes will be due. These liabilities are established when the
Company believes that certain positions might be challenged despite the Company’s belief that the tax return positions are fully supportable. The recorded
liability is adjusted in light of changing facts and circumstances. The provision for (benefit from) income taxes includes the impact of the recorded liability
and changes thereto.

The Company recognizes interest and penalties related to uncertain tax positions within other income (expense) in the accompanying consolidated

statements of operations and comprehensive income. Accrued interest and penalties are included in accrued income taxes in the consolidated balance sheets.

On December 22, 2017, the Tax Cuts and Jobs Act (the “TCJA”) was enacted which, among other things, lowered the U.S. corporate income tax rate
to 21% from 35%, repealed the domestic production activity deductions, limited the deductibility of certain executive compensation and interest expense, and
established a modified territorial system requiring a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries. Beginning in 2018,
the TCJA also requires a minimum tax on certain future earnings generated by foreign subsidiaries while providing for future tax-free repatriation of such
earnings through a 100% dividends-received deduction. While the reduction in the U.S. corporate tax rate under the TCJA is not effective until 2018, under
GAAP,  changes  in  tax  rates  are  accounted  for  in  the  period  enacted.  Therefore,  in  accordance  with  ASC  Topic  740,  Income Taxes,  and  Staff  Accounting
Bulletin 118 (“SAB 118”), the Company recognized a provisional income tax charge in the fourth quarter of 2017 of $14,098 related to the TCJA based on its
initial  analysis  using  available  information  and  estimates.  The  provisional  charge  is  comprised  of  $10,031  related  to  the  one-time  deemed  repatriation  of
accumulated earnings of foreign subsidiaries and related withholding taxes and $4,067 related primarily to the remeasurement of net deferred tax assets as a
result  of  the  reduction  in  the  U.S.  corporate  income  tax  rate  effected  by  the  TCJA.  As  a  result,  applicable  U.S.  and  foreign  taxes  have  been  provided  on
substantially all of the Company’s accumulated earnings of foreign subsidiaries previously considered indefinitely reinvested. The Company’s accounting for
the  impacts  of  the  TCJA  is  complete  as  of  December  31,  2018,  and  the  Company  has  not  recorded  any  material  adjustments  to  the  provisional  amounts
recorded in the fourth quarter of 2017 related to the TCJA.  Although the Company no longer considers these amounts provisional, the determination of the
TCJA’s  income  tax  effects  may  change  as  a  result  of  future  legislation  or  further  interpretation  of  the  TCJA  based  on  the  publication  of  regulations  and
guidance from the Internal Revenue Service and state tax authorities.

While  the  intent  of  TCJA  was  to  provide  for  a  territorial  tax  system,  effective  for  taxable  years  beginning  after  January  1,  2018,  taxpayers  are
subjected to the global intangible low-taxed income (“GILTI”) provisions. The GILTI provisions require the Company to currently recognize in U.S. taxable
income a deemed dividend inclusion of foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. During 2018,
the Company recorded an income tax charge of $4.4 million related to GILTI.  The Company has made an accounting policy election, as allowed by the SEC
and  FASB,  to  recognize  the  impacts  of  GILTI  within  the  period  incurred.    Therefore,  no  U.S.  deferred  taxes  are  provided  on  GILTI  inclusions  of  future
foreign subsidiary earnings.

Comprehensive Income

Comprehensive  income  includes  net  income  as  well  as  other  changes  in  stockholders’  equity  (deficit)  that  result  from  transactions  and  economic
events other than those with stockholders. Comprehensive income for the periods presented consists of net income and the change in the cumulative foreign
currency translation adjustment.

Net Income (Loss) per Share

The Company follows the two-class method when computing net income (loss) per share as the Company has issued shares that meet the definition of
participating  securities.  The  two-class  method  determines  net  income  (loss)  per  share  for  each  class  of  common  and  participating  securities  according  to
dividends  declared  or  accumulated  and  participation  rights  in  undistributed  earnings.  The  two-class  method  requires  income  available  to  common
stockholders  for  the  period  to  be  allocated  between  common  and  participating  securities  based  upon  their  respective  rights  to  receive  dividends  as  if  all
income for the period had been distributed.

84

 
Basic  net  income  (loss)  per  share  attributable  to  common  stockholders  is  computed  by  dividing  the  net  income  (loss)  attributable  to  common
stockholders  by  the  weighted-average  number  of  shares  of  common  stock  outstanding  for  the  period.  Diluted  net  income  (loss)  attributable  to  common
stockholders  is  computed  by  adjusting  net  income  (loss)  attributable  to  common  stockholders  to  reallocate  undistributed  earnings  based  on  the  potential
impact of dilutive securities. Diluted net income (loss) per share attributable to common stockholders is computed by dividing the diluted net income (loss)
attributable  to  common  stockholders  by  the  weighted-average  number  of  shares  of  common  stock  outstanding  for  the  period,  including  potential  dilutive
common shares. For purpose of this calculation, outstanding stock-based awards and convertible preferred stock are considered potential dilutive common
shares.

Impact of Recently Adopted Accounting Standards

In November 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU
2016-18”), which requires that amounts generally described as restricted cash or restricted cash equivalents be included with cash and cash equivalents when
reconciling beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The standard is effective for public companies for
annual periods beginning after December 15, 2017, including interim periods within those fiscal years. The standard is effective for private companies, and
emerging  growth  companies  that  choose  to  take  advantage  of  the  extended  transition  periods,  for  annual  periods  beginning  after  December  15,  2018,  and
interim  periods  within  fiscal  years  beginning  after  December  15,  2019.  The  Company  retrospectively  adopted  ASU  2016-18  during  the  second  quarter  of
2018, and there was no material impact on its consolidated financial statements.

Impact of Recently Issued Accounting Standards

In  May  2014,  the  FASB  issued  ASU  2014-09,  Revenue  from  Contracts  with  Customers (Topic 606)  (“ASU  2014-09”),  which  supersedes  existing
revenue recognition guidance under GAAP. The core principle of this standard is that an entity should recognize revenue to depict the transfer of promised
goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.
In  August  2015,  the  FASB  issued  ASU  2015-14,  Revenue  from  Contracts  with  Customers  (Topic  606):  Deferral  of  the  Effective  Date,  which  delays  the
effective date of ASU 2014-09 such that the standard is effective for public companies for annual periods beginning after December 15, 2017 and for interim
periods  within  those  fiscal  years.  The  standard  is  effective  for  private  companies,  and  emerging  growth  companies  that  choose  to  take  advantage  of  the
extended transition periods, for annual reporting periods beginning after December 15, 2018. Entities are not permitted to adopt the standard earlier than the
original effective date for public entities. This standard can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect
adjustment as of the date of adoption. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus
Agent Considerations (“ASU 2016-08”), which further clarifies the implementation guidance on principal versus agent considerations in ASU 2014-09. In
April 2016, the FASB issued ASU 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing (“ASU
2016-10”),  clarifying  the  implementation  guidance  on  identifying  performance  obligations  and  licensing.  In  May  2016,  the  FASB  issued  ASU  2016-12,
Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”), which clarifies the objective
of the collectibility criterion, presentation of taxes collected from customers, non-cash consideration, contract modifications at transition, completed contracts
at transition and how guidance in ASU 2014-09 is retrospectively applied. ASU 2016-08, ASU 2016-10 and ASU 2016-12 have the same effective dates and
transition requirements as ASU 2014-09.

The Company has elected to adopt ASU 2014-09 using the modified retrospective method. The Company has preliminarily quantified the impact that
the adoption would have had on contracts not completed as of the adoption date and will recognize a cumulative effect adjustment to the opening balance of
retained  earnings  as  of  the  adoption  date.  The  Company  expects  to  record  a  preliminary  adjustment  to  opening  retained  earnings  in  the  amount  of
approximately  $4,000  to  $5,000  primarily  relates  to  the  application  of  the  clarified  collectibility  criterion  to  contracts  that  the  Company  had  previously
determined were extended payment term arrangements and recognized revenue only to the extent that payment amounts were due or received. The Company
also expects to record an adjustment related to the cost of goods sold on these extended payment term arrangements, which is preliminarily estimated to be
immaterial.  The  adoption  of  ASU  2014-09  will  also  have  an  impact  on  the  Company’s  accounting  for  costs  to  obtain  customer  contracts,  which  relate
primarily to commissions paid to the Company’s sales representatives and to resellers and sales agents. The Company currently expenses commissions and
costs to obtain customer contracts when incurred. Under ASU 2014-09, the Company will capitalize and amortize these costs over the expected period of
benefit. The Company is finalizing an analysis of commissions and costs to obtain customer contracts for contracts not completed as of the adoption date
which will result in the creation of an asset as a cumulative effect adjustment to be amortized over the expected period of benefit. The Company is in the
process of finalizing the documentation of its assumptions used in quantifying the impact of adopting the new revenue standard. Therefore, the quantification
and  assessment  disclosed  herein  is  preliminary  and  subject  to  change.  The  finalization  of  this  documentation  could  result  in  a  material  impact  to  the
consolidated financial statements.

85

 
 
In  February  2016,  the  FASB  issued  ASU  2016-02,  Leases  (“ASU  2016-02”),  which  will  require  lessees  to  recognize  most  leases  on  their  balance
sheets  as  a  right-of-use  asset  with  a  corresponding  lease  liability,  and  lessors  to  recognize  a  net  lease  investment.  Additional  qualitative  and  quantitative
disclosures will also be required. This guidance is effective for public companies for annual reporting periods beginning after December 15, 2018 and for
interim periods within those fiscal years. This guidance is effective for private companies, and emerging growth companies that choose to take advantage of
the  extended  transition  periods,  for  annual  reporting  periods  beginning  after  December  15,  2019,  and  interim  periods  within  fiscal  years  beginning  after
December 15, 2020. Early application is permitted. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842: Leases (“ASU
2018-10”), which affects narrow aspects of the guidance issued in the amendments in ASU 2016-02. ASU 2018-10 has the same effective dates and transition
requirements as ASU 2016-02. In July 2018, the FASB issued update ASU 2018-11, Leases (Topic 842), Targeted Improvements (“ASU 2018-11”), which
provided  for  an  additional  (and  optional)  transition  method  with  which  to  adopt  the  new  lease  standard  in  ASU  2016-02.  The  additional  method  allows
entities to apply the new leases standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the
period of adoption. Additionally, in December 2018, the FASB issued update ASU 2018-20, Leases (Topic 842) – Narrow-Scope Improvements for Lessors
(“ASU 2018-20”), which addresses stakeholders’ concerns about the operability challenges encountered in determining certain lessor costs paid by lessees
directly to third parties by requiring lessors to exclude from variable payments, and thus from lease revenue, lessor costs paid by a lessee directly to a third
party. The amendments in ASU 2018-20 also clarify that costs excluded from the consideration in a contract that are paid directly to a third party by a lessor
and  reimbursed  by  the  lessee  are  lessor  costs  to  be  accounted  for  as  variable  payments.  The  Company  is  currently  assessing  the  potential  impact  that  the
adoption of ASU 2016-02, ASU 2018-10, ASU 2018-11 and ASU 2018-20 will have on its consolidated financial statements. The Company is in the process
of reviewing existing lease agreements to assess the impact this guidance may have on the consolidated financial statements. The Company currently expects
that most of its operating lease commitments will be subject to the new standard and will affect the consolidated balance sheet by recognizing new right-of-
use assets and operating lease liabilities upon the adoption of ASU 2016-02, which will increase the total assets and total liabilities that it reports relative to
such amounts prior to adoption.

In June 2016, the FASB issued ASU 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). This guidance requires that
financial assets measured at amortized cost be presented at the net amount expected to be collected. The measurement of expected credit losses is based on
historical experience, current conditions and reasonable and supportable forecasts that affect the collectibility. This guidance is effective for public companies
for  annual  reporting  periods  beginning  after  December  15,  2019  and  for  interim  periods  within  those  fiscal  years.  This  guidance  is  effective  for  private
companies, and emerging growth companies that choose to take advantage of the extended transition periods, for annual reporting periods beginning after
December  15,  2020,  and  interim  periods  within  fiscal  years  beginning  after  December  15,  2021.  Additionally,  in  November  2018,  the  FASB  issued  ASU
2018-19,  Codification  Improvements  to  Topic  326,  Financial  Instruments—Credit  Losses  (“ASU  2018-19”),  which  mitigates  transition  complexity  by
requiring that for nonpublic business entities the amendments in ASU 2016-13 are effective for fiscal years beginning after December 15, 2021, including
interim periods within those fiscal years. The amendments in ASU 2018-19 also clarify that receivables arising from operating leases are not within the scope
of Subtopic 326-20, but instead, should be accounted for in accordance with Topic 842, Leases. The Company is currently assessing the potential impact that
the adoption of ASU 2016-13 and ASU 2018-19 will have on its consolidated financial statements.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-
15”), to address diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard
is effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. The standard is
effective  for  private  companies,  and  emerging  growth  companies  that  choose  to  take  advantage  of  the  extended  transition  periods,  for  annual  periods
beginning  after  December  15,  2018,  and  interim  periods  within  fiscal  years  beginning  after  December  15,  2019.  The  Company  is  currently  assessing  the
potential impact that the adoption of ASU 2016-15 will have on its consolidated financial statements.

In October 2016, the FASB issued ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other than Inventory (“ASU 2016-16”),
which  requires  the  recognition  of  the  income  tax  consequences  of  an  intra-entity  transfer  of  an  asset,  other  than  inventory,  when  the  transfer  occurs.  The
standard is effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those fiscal years. The
standard  is  effective  for  private  companies,  and  emerging  growth  companies  that  choose  to  take  advantage  of  the  extended  transition  periods,  for  annual
periods  beginning  after  December  15,  2018,  and  interim  reporting  periods  within  annual  periods  beginning  after  December  15,  2019.  The  Company  is
currently assessing the potential impact that the adoption of ASU 2016-16 will have on its consolidated financial statements.

86

 
In  August  2017,  the  FASB  issued  ASU  2017-12,  Derivatives  and  Hedging—Targeted  Improvements  to  Accounting  for  Hedging  Activities  (“ASU
2017-12”),  which  aims  to  improve  the  financial  reporting  of  hedging  relationships  to  better  portray  the  economic  results  of  an  entity’s  risk  management
activities in its financial statements. The standard is effective for public companies for annual periods beginning after December 15, 2018, including interim
periods  within  those  fiscal  years.  The  standard  is  effective  for  private  companies,  and  emerging  growth  companies  that  choose  to  take  advantage  of  the
extended  transition  periods,  for  annual  periods  beginning  after  December  15,  2019,  and  interim  reporting  periods  within  annual  periods  beginning  after
December  15,  2020.  The  Company  is  currently  assessing  the  potential  impact  that  the  adoption  of  ASU  2017-12  will  have  on  its  consolidated  financial
statements.

In June 2018, the FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718) (“ASU 2018-07”), which expands the scope of Topic
718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments specify that Topic 718 applies to all
share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based
payment awards. The standard is effective for public companies for annual periods beginning after December 15, 2018, including interim periods within those
fiscal years. The standard is effective for private companies, and emerging growth companies that choose to take advantage of the extended transition periods,
for  annual  periods  beginning  after  December  15,  2019,  and  interim  reporting  periods  within  annual  periods  beginning  after  December  15,  2020.  Early
adoption is permitted, but no earlier than an entity’s adoption date of Topic 606. The Company is currently assessing the potential impact that the adoption of
ASU 2018-07 will have on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (“ASU 2018-13”), which modifies the disclosure requirements on fair value
measurements  in  Topic  820,  Fair  Value  Measurement,  regarding  transfers  between  levels  of  financial  instruments,  amounts  of  unrealized  gains  and  losses
included  in  other  comprehensive  income  for  Level  3  fair  value  measurements  and  the  information  used  to  determine  the  fair  value  of  Level  3  fair  value
measurements. The standard is effective for both public and private companies, and emerging growth companies that chose to take advantage of the extended
transition periods, for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted. The
Company is currently assessing the potential impact that the adoption of ASU 2018-13 will have on its consolidated financial statements.

The Company’s cash equivalents include certificates of deposit and money market mutual funds, which are valued using Level 1 or Level 2 inputs in
the  fair  value  hierarchy.  The  Company’s  marketable  securities  consist  of  certificates  of  deposit,  which  are  valued  using  Level  2  inputs  in  the  fair  value
hierarchy. The Company’s foreign currency forward contracts are valued using Level 2 inputs in the fair value hierarchy. The Company’s SARs are valued
using as Level 3 inputs in the fair value hierarchy based on management’s judgment and the assumptions set forth in Note 12 as there is no market activity to

During the years ended December 31, 2018, 2017 and 2016 there were no transfers between Level 1, Level 2 and Level 3.

The liability for SARs in the table above consists of the fair value of the SARs granted to the Company’s employees. The fair values of the SARs are
based on significant inputs not observable in the market, which represents a Level 3 measurement within the fair value hierarchy. The Company’s valuation of
these SARs utilized the Black-Scholes option-pricing model, which incorporates assumptions and estimates to determine their fair values (see Note 12). The
Company assesses these assumptions and estimates on a quarterly basis as additional information impacting the assumptions is obtained. Changes in the fair
value of the SARs liability are recognized as stock-based compensation expense in the consolidated statements of operations and comprehensive income.

The following table provides a summary of changes in the fair values of the Company’s SARs liability, for which fair value is determined by Level 3

inputs:

The Company has certain international customers that are billed in foreign currencies. To mitigate the volatility related to fluctuations in the foreign
exchange rates for accounts receivable denominated in foreign currencies, the Company enters into foreign currency forward contracts. As of December 31,
2018, the Company had foreign currency forward contracts outstanding with notional amounts totaling 25,741 euros maturing in the second and third quarters
of 2019. As of December 31, 2017, the Company had foreign currency forward contracts outstanding with notional amounts totaling 5,924 Euros maturing in
the first and second quarter of 2018.

The Company’s foreign currency forward contracts economically hedge certain risk but are not designated as hedges for financial reporting purposes,
and accordingly, all changes in the fair value of these derivative instruments are recorded as unrealized foreign currency transaction gains or losses and are
included  in  the  consolidated  statements  of  operations  and  comprehensive  income  as  a  component  of  other  income  (expense).  The  Company  records  all
derivative  instruments  in  the  consolidated  balance  sheet  at  their  fair  values.  As  of  December  31,  2018,  the  Company  recorded  an  asset  of  $254  and  as  of
December 31, 2018 and 2017, the Company recorded a liability of $252 and $150, respectively, related to outstanding foreign currency forward contracts,
which  were  included  in  prepaid  expenses  and  other  current  assets  and  in  accrued  expenses  and  other  current  liabilities,  respectively,  in  the  consolidated
balance sheets.

The Company has concluded that net deferred tax assets will be recovered based upon its expectation that current and future earnings will provide
sufficient taxable income to realize the recorded net tax assets. However, the realization of the Company’s net deferred tax assets cannot be assured, and to the
extent that future taxable income against which these tax assets may be applied is not sufficient, some or all of the Company’s recorded net deferred tax assets
would  not  be  realizable.  The  Company  is  required  to  compute  income  tax  expense  in  each  jurisdiction  in  which  it  operates.  This  process  requires  the
Company to project its current tax liability and estimate its deferred tax assets and liabilities, including tax credit carryforwards. In assessing the need for a
valuation allowance against its net deferred tax assets, the Company considers its recent operating results, future taxable income projections and feasible tax
planning strategies. As of December 31, 2018, the Company recorded a $3,926 valuation allowance related to its state research and development tax credit
carryforwards that are not more likely than not to be realized.

On December 22, 2017, the TCJA was enacted which, among other things, lowered the U.S. corporate income tax rate to 21% from 35%, repealed the
domestic  production  activity  deductions,  limited  the  deductibility  of  certain  executive  compensation  and  interest  expense,  and  established  a  modified
territorial system requiring a mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries. Beginning in 2018, the TCJA also required
a minimum tax on certain future earnings generated by foreign subsidiaries while providing for future tax-free repatriation of such earnings through a 100%
dividends-received deduction. While the reduction in the U.S. corporate tax rate under the TCJA is not effective until 2018, under GAAP, changes in tax rates
are accounted for in the period enacted. Therefore, in accordance with ASC Topic 740, Income Taxes, and SAB 118, the Company recognized a provisional
charge in the fourth quarter of 2017 of $14,098 related to the TCJA based on its initial analysis using available information and estimates. The provisional
charge is comprised of $10,031 related to the one-time deemed repatriation of accumulated earnings of foreign subsidiaries and related withholding taxes and
$4,067  related  primarily  to  the  remeasurement  of  net  deferred  tax  assets  as  a  result  of  the  reduction  in  the  U.S.  corporate  income  tax  rate  effected  by  the
TCJA. As a result, applicable U.S. and foreign taxes have been provided on substantially all of the Company’s accumulated earnings of foreign subsidiaries
previously  considered  indefinitely  reinvested.  The  Company’s  accounting  for  the  impacts  of  the  TCJA  is  complete  as  of  December  31,  2018,  and  the
Company has not recorded any material adjustments to the provisional amounts recorded in the fourth quarter of 2017 related to the TCJA.  Although the
Company no longer considers these amounts provisional, the determination of the TCJA’s income tax effects may change as a result of future legislation or
further interpretation of the TCJA based on the publication of regulations and guidance from the Internal Revenue Service and state tax authorities.

While  the  intent  of  TCJA  was  to  provide  for  a  territorial  tax  system,  effective  for  taxable  years  beginning  after  January  1,  2018,  taxpayers  are
subjected to the GILTI provisions. The GILTI provisions require the Company to currently recognize in U.S. taxable income a deemed dividend inclusion of
foreign subsidiary earnings in excess of an allowable return on the foreign subsidiary’s tangible assets. During 2018, the Company recorded an income tax
charge of $4,410 related to GILTI.  The Company has made an accounting policy election, as allowed by the SEC and FASB, to recognize the impacts of
GILTI within the period incurred.  Therefore, no U.S. deferred taxes are provided on GILTI inclusions of future foreign subsidiary earnings.

As of December 31, 2018, the Company had available state research and development tax credit carryforwards of $7,923 which begin to expire in
2030.      Management  believes  that  it  is  more  likely  than  not  that  the  Company  will  not  realize  the  benefit  of  all  of  its  state  research  and  development  tax
credits and thus has provided a $3,926 valuation allowance relating to these tax credit carryforwards.

As of December 31, 2018, substantially all of the Company’s unremitted earnings have been taxed through either the deemed repatriation tax or as
GILTI income.  Of the total amount of undistributed earnings, $25,722 is not indefinitely reinvested and we have recorded a $2,572 deferred tax liability and
a $1,139 foreign tax credit associated with the withholding taxes on the future distribution.  The remaining unremitted earnings of our foreign subsidiaries are
either indefinitely reinvested or could be remitted with an immaterial tax cost.

Interest and penalties related to uncertain tax positions are recorded in the consolidated statements of operations and comprehensive income within
other  income  (expense)  and  totaled  $211,  $14  and  $14  for  the  years  ended  December  31,  2018,  2017  and  2016,  respectively.  The  liability  recorded  for
potential penalties and interest was $369 and $158 as of December 31, 2018 and 2017, respectively. The Company had a total recorded liability of $3,038 and
$1,142 related to uncertain tax positions, inclusive of penalties and interest, as of December 31, 2018 and 2017, respectively, which is included in accrued
income taxes, net of current portion in the consolidated balance sheets.  As of December 31, 2018, the amount of uncertain tax benefits that, if recognized,
would impact the effective income tax rate is $1,093.

The aggregate changes in the balance of gross uncertain tax positions, which excludes interest and penalties, for the years ended December 31, 2018,

2017 and 2016 were as follows:

Balance at January 1, 2016

Increases related to tax positions taken during prior years

The  Company  and  its  subsidiaries  file  income  tax  returns  in  the  U.S.  federal  jurisdiction  as  well  as  various  states  and  foreign  jurisdictions.  The
Company  and  certain  subsidiaries  have  tax  years  that  remain  open  and  are  subject  to  examination  by  tax  authorities  in  the  following  major  taxing
jurisdictions: United States for tax years 2015 through 2018, Ireland for tax years 2014 through 2018, China for tax years 2013 through 2018 (for transfer
pricing adjustments, the statute of limitation in China is ten years). The Company files income tax returns on a combined, unitary, or stand-alone basis in
multiple state and local jurisdictions, which generally have statutes of limitations from three to four years. If any issues addressed in the Company’s tax audits
are resolved in a manner not consistent with management’s expectations, the Company would be required to adjust its provision for income tax in the period
such resolution occurs. Although timing of the resolution and/or closure of audits is highly uncertain, the Company does not believe it is reasonably possible
that its unrecognized tax benefits will materially change in the next 12 months.

On December 20, 2016, the Company entered into a credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, various lenders and
JPMorgan Chase Bank, N.A. and Barclays Bank PLC providing for (i) a term loan facility of $300,000 and (ii) a revolving credit facility of up to $25,000 in
revolving credit loans and letters of credit.

As of December 31, 2018 and 2017, $294,000 and $297,000 in principal amount, respectively, was outstanding under the term loan facility (the “Term
Loans”) and the Company did not have any outstanding borrowings under the revolving credit facility; however, as of December 31, 2017, the Company had
used $1,000 under the revolving credit facility for a stand-by letter of credit that served as collateral for a stand-by letter of credit issued by Bank of America
to one of the Company’s customers pursuant to a contractual performance guarantee. As of December 31, 2018, the stand-by letter of credit that served as
collateral  was  terminated,  and  the  Company  did  not  use  any  amount  under  the  revolving  credit  facility.  In  addition,  the  Company  may,  subject  to  certain
conditions, including the consent of the administrative agent and the institutions providing such increases, increase the facilities by an unlimited amount so
long as the Company is in compliance with specified leverage ratios, or otherwise by up to $70,000.

Borrowings under the facilities bear interest at a floating rate, which can be either a Eurodollar rate plus an applicable margin or, at the Company’s
option, a base rate (defined as the highest of (x) the JPMorgan Chase, N.A. prime rate, (y) the federal funds effective rate, plus one-half percent (0.50%) per
annum and (z) a one-month Eurodollar rate plus 1.00% per annum) plus an applicable margin. The applicable margin for borrowings under the term loan
facility is 4.00% per annum for Eurodollar rate loans (subject to a 1.00% per annum interest rate floor) and 3.00% per annum for base rate loans. As a result
of the completion of the Company’s IPO in December 2017, the applicable margin for borrowings under the revolving credit facility is 1.75% per annum for
Eurodollar rate loans and 0.75% per annum for base rate loans, subject to reduction based on the Company’s maintaining of specified net leverage ratios. The
interest rates payable under the facilities are subject to an increase of 2.00% per annum during the continuance of any payment default.

For  Eurodollar  rate  loans,  the  Company  may  select  interest  periods  of  one,  two,  three  or  six  months  or,  with  the  consent  of  all  relevant  affected
lenders, twelve months. Interest will be payable at the end of the selected interest period, but no less frequently than every three months within the selected
interest period. Interest on any base rate loan is not set for any specified period and is payable quarterly. The Company has the right to convert Eurodollar rate
loans  into  base  rate  loans  and  the  right  to  convert  base  rate  loans  into  Eurodollar  rate  loans  at  its  option,  subject,  in  the  case  of  Eurodollar  rate  loans,  to
prepayment penalties if the conversion is effected prior to the end of the applicable interest period. As of December 31, 2018, the interest rate on the Term
Loans was 6.52%  per  annum,  which  was  based  on  a  one-month  Eurodollar  rate  of  2.52%  per  annum  plus  the  applicable  margin  of  4.00% per annum for
Eurodollar rate loans. As of December 31, 2017, the interest rate on the Term Loans was 5.69% per annum, which was based on a three-month Eurodollar rate
of 1.69% per annum plus the applicable margin of 4.00% per annum for Eurodollar rate loans.

Upon entering into the term loan facility, the Company incurred debt issuance costs of $7,811, which were initially recorded as a reduction of the debt
liability and are amortized to interest expense using the effective interest method from the issuance date of the Term Loan until the maturity date. Principal
payments of $3,000 were made under the term loan facility during the years ended December 31, 2018 and 2017. No principal payments were made during
the year ended December 31, 2016. Interest expense, including the amortization of debt issuance costs, totaled $19,146, $16,800 and $538 for the years ended
December 31, 2018, 2017 and 2016, respectively.

The revolving credit facility also requires payment of quarterly commitment fees at a rate of 0.25% per annum on the difference between committed
amounts  and  amounts  actually  borrowed  under  the  facility  and  customary  letter  of  credit  fees.  For  the  years  ended  December  31,  2018  and  2017,  interest
expense related to the fee for the unused amount of the revolving credit facility totaled $62 and $61, respectively.

The  Term  Loans  mature  on  December  20,  2023,  and  the  revolving  credit  facility  matures  on  December  20,  2021.  The  Term  Loans  are  subject  to
amortization in equal quarterly installments, which commenced on March 31, 2017, of principal in an annual aggregate amount equal to 1.0% of the original
principal amount of the Term Loans of $300,000, with the remaining outstanding balance payable at the date of maturity.

Voluntary prepayments of principal amounts outstanding under the term loan facility are permitted at any time; however, if a prepayment of principal
is made with respect to a Eurodollar loan on a date other than the last day of the applicable interest period, the Company is required to compensate the lenders
for  any  funding  losses  and  expenses  incurred  as  a  result  of  the  prepayment.  Prior  to  the  revolving  credit  facility  maturity  date,  funds  borrowed  under  the
revolving credit facility may be borrowed, repaid and reborrowed, without premium or penalty.

In  addition,  the  Company  is  required  to  make  mandatory  prepayments  under  the  facilities  with  respect  to  (i)  100%  of  the  net  cash  proceeds  from
certain  asset  dispositions  (including  casualty  and  condemnation  events)  by  the  Company  or  certain  of  its  subsidiaries,  subject  to  certain  exceptions  and
reinvestment  provisions,  (ii)  100%  of  the  net  cash  proceeds  from  the  issuance  or  incurrence  of  any  additional  debt  by  the  Company  or  certain  of  its
subsidiaries, subject to certain exceptions, and (iii) 50% of the Company’s excess cash flow, as defined in the credit agreement, subject to reduction upon its
achievement of specified performance targets.

The  facilities  are  secured  by,  among  other  things,  a  first  priority  security  interest,  subject  to  permitted  liens,  in  substantially  all  of  the  Company’s
assets and all of the assets of certain of its subsidiaries and a pledge of certain of the stock of certain of its subsidiaries, in each case subject to specified
exceptions. The facilities contain customary affirmative and negative covenants, including certain restrictions on the Company’s ability to pay dividends, and,
with respect to the revolving credit facility, a financial covenant requiring the Company to maintain a specified total net leverage ratio in the event that on the
last day of any fiscal quarter the Company has utilized more than 30% of its borrowing capacity under the facility. As of December 31, 2018 and 2017, the
Company had not utilized more than 30% of its borrowing capacity under the revolving credit facility and compliance with the financial covenant was not
applicable.

Commercial Mortgage Loan

On  July  1,  2015,  the  Company  entered  into  a  commercial  mortgage  loan  agreement  in  the  amount  of  $7,950  (the  “Mortgage  Loan”).  Borrowings
under the Mortgage Loan bear interest at a rate of 3.5% per annum and are repayable in 60 monthly installments of $46, consisting of principal and interest
based on a 20-year amortization schedule. The remaining amount of unpaid principal under the Mortgage Loan is due on the maturity date of July 1, 2020.
Upon entering into the Mortgage Loan, the Company incurred debt issuance costs of $45, which was initially recorded as a direct deduction from the debt
liability and are amortized to interest expense using the effective interest method from issuance date of the loan until the maturity date.

2017 and 2016, respectively.

The  Mortgage  Loan  is  secured  by  the  land  and  building  purchased  in  March  2015  and  subjects  the  Company  to  various  affirmative,  negative  and
financial covenants, including maintenance of a minimum debt service ratio. The Company was in compliance with all covenants of the Mortgage Loan as of
December 31, 2018 and 2017.

12. Stock-based Compensation

2003 Stock Incentive Plan

The Company’s 2003 Stock Incentive Plan, as amended (the “2003 Plan”), provided for the grant of qualified incentive stock options, nonqualified
stock options, restricted stock or other stock-based awards to the Company’s employees, officers, directors, advisers and outside consultants. The number of
shares  authorized  for  grant  under  the  2003  Plan,  as  amended,  was  32,500  shares.  The  2003  Plan  was  administered  by  the  board  of  directors,  or  at  the
discretion of the board of directors, by a committee of the board or by one or more executive officers of the Company. The exercise prices, vesting and other
restrictions  were  determined  at  the  discretion  of  the  board  of  directors,  or  their  committee  or  by  one  or  more  executive  officers  of  the  Company,  if  so
delegated.

The 2003 Plan was terminated in August 2011, and the remaining 2,140 shares available for issuance under the plan at that time were transferred to
the Company’s 2011 Stock Incentive Plan (the “2011 Plan”). The shares of common stock underlying any awards that are forfeited, canceled, repurchased or
are otherwise terminated by the Company under the 2003 Plan will be added back to the shares of common stock available for issuance under the Company’s
2017 Stock Incentive Plan (the “2017 Plan”).

2011 Stock Incentive Plan

The 2011 Plan provided for the Company to sell or issue common stock or restricted common stock, or to grant qualified incentive stock options,
nonqualified stock options, SARs, RSUs or other stock-based awards to the Company’s employees, officers, directors, advisers and outside consultants. The
2011 Plan was administered by the board of directors, or at the discretion of the board of directors, by a committee of the board. The exercise prices, vesting
and other restrictions were determined at the discretion of the board of directors, or their committee if so delegated, except that the exercise price per share of
stock options could not be less than 100% of the fair market value of common stock on the date of grant and the term of the stock option could not be greater
than ten years. The stock options generally vest over a four-year period and expire ten years from the date of grant. Certain options provide for accelerated
vesting if there is a change in control (as defined in the stock option agreements).

The 2011 Plan was terminated for the purpose of making new grants in December 2017, and the remaining 2,855 shares available for issuance under
the 2011 Plan at that time were transferred to the 2017 Plan. Awards outstanding under the 2011 Plan at the time of the 2011 Plan’s termination will continue
to  be  governed  by  their  existing  terms.    The  shares  of  common  stock  underlying  any  awards  that  are  forfeited,  canceled,  repurchased  or  are  otherwise
terminated by the Company under the 2011 Plan will be added back to the shares of common stock available for issuance under the 2017 Plan.

99

 
2017 Stock Incentive Plan

On November 17, 2017, the Company’s board of directors adopted, and on November 30, 2017, the Company’s stockholders approved, the 2017 Plan,
which became effective immediately prior to the effectiveness of the registration statement for the IPO. The 2017 Plan provides for the grant of incentive
stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based awards. The number
of shares initially reserved for issuance under the 2017 Plan is the sum of 7,161 shares, plus the number of shares (up to 18,746 shares) equal to the sum of (i)
the number of shares remaining available for issuance under the 2003 Plan and 2011 Plan upon the effectiveness of the 2017 Plan and (ii) the number of
shares  of  common  stock  subject  to  outstanding  awards  under  the  2003  Plan  and  2011  Plan  that  expire,  terminate  or  are  otherwise  surrendered,  canceled,
forfeited or repurchased by the Company at their original issuance price pursuant to a contractual repurchase right. The number of shares of common stock
that  may  be  issued  under  the  2017  Plan  will  automatically  increase  on  each  January  1,  beginning  with  the  fiscal  year  ending  December  31,  2019  and
continuing  for  each  fiscal  year  until,  and  including,  the  fiscal  year  ending  December  31,  2027,  equal  to  the  least  of  (i)  20,000  shares,  (ii)  4%  of  the
outstanding  shares  of  common  stock  on  such  date  and  (iii)  an  amount  determined  by  the  Company’s  board  of  directors.  The  shares  of  common  stock
underlying any awards that are forfeited, canceled, repurchased or are otherwise terminated by the Company under the 2017 Plan will be added back to the
shares of common stock available for issuance under the 2017 Plan.  The total number of shares authorized for issuance under the 2017 Plan was 10,154
shares as of December 31, 2018, of which 8,422 shares remained available for future grant.

Stock Option Valuation

The fair value of each option award is estimated on the date of grant using the Black-Scholes option-pricing model that uses the assumptions noted in
the  table  below.  Expected  volatility  for  the  Company’s  common  stock  was  determined  based  on  an  average  of  the  historical  volatility  of  a  peer  group  of
similar public companies. The expected term of options granted was calculated using the simplified method, which represents the average of the contractual
term  of  the  option  and  the  weighted-average  vesting  period  of  the  option.  The  Company  uses  the  simplified  method  because  it  does  not  have  sufficient
historical option exercise data to provide a reasonable basis upon which to estimate the expected term. The expected dividend yield is based on the fact that
the Company does not have a history of paying cash dividends, except for the special dividends declared in November 2014, June 2016, December 2016, May
2017 and November 2017 (see Note 10), and in those circumstances, the board of directors approved cash dividends to be paid to holders of the Company’s
stock options and SARs upon vesting as an equitable adjustment to the holders of such instruments. The risk-free rate for periods within the expected life of
the option is based upon the U.S. Treasury yield curve in effect at the time of grant.

In determining the exercise prices for options granted prior to the Company’s IPO, the Company’s board of directors considered the fair value of the
common stock as of the measurement date. The fair value of the common stock was determined by the board of directors at each award grant date based upon
a  variety  of  factors,  including  the  results  obtained  from  an  independent  third-party  valuation  of  the  Company’s  common  stock,  the  Company’s  financial
position and historical financial performance, the status of technological developments within the Company’s products, the composition and ability of the
current management team, an evaluation or benchmark of the Company’s competition, the current business climate in the marketplace, the illiquid nature of
the common stock, the effect of the rights and preferences of the holders of the Company’s convertible preferred stock, and the prospects of a liquidity event,
among others. Subsequent to the completion of the IPO, the Company uses the closing price of its common stock as reported on the Nasdaq Global Select
Market on the applicable date of grant to determine the fair value of the shares of common stock underlying stock options.

$5,001,  respectively.  The  aggregate  intrinsic  value  is  calculated  as  the  difference  between  the  exercise  price  of  the  stock  options  and  the  fair  value  of  the
Company’s common stock for those stock options that had exercise prices lower than the fair value of the Company’s common stock.

Restricted Stock Units

On March 8, 2018, June 6, 2018, June 14, 2018, September 27, 2018, November 27, 2018 and December 14, 2018, the Company granted 103, 7, 83,

244 and 2,103 RSUs, respectively, under the 2011 Plan. The RSUs vest ratably over a one- to four-year period from the date of grant. The grant-date fair
value  of  each  RSU  award  is  being  recorded  as  stock-based  compensation  expense  on  a  straight-line  basis,  net  of  estimated  forfeitures,  over  the  requisite
service period for the RSUs, which is generally one to four years. The fair value of each RSU on the date of grant is the estimated fair value of the underlying
common  stock  on  the  date  of  the  grant.  A  summary  of  RSU  activity  under  the  2011  Plan  and  the  2017  Plan  for  the  year  ended  December  31,  2018  is  as

The price of the underlying common stock on the date of grant was $12.24 per share and the grant-date fair value was $4.52 per SAR. The SARs vest over a
four-year  period  from  the  date  of  grant  and  expire  ten  years  from  the  date  of  grant.  As  of  December  31,  2018,  240  SARs  were  outstanding  and  35  were
unvested. As of December 31, 2018, there were 205 SARs exercisable and the fair value of each SAR was $7.21 per SAR. The fair value of the SAR liability

Consulting Agreement with Bill Styslinger

In March 2012, the Company entered into a consulting agreement with Bill Styslinger, a member of its board of directors, for the provision of sales
management, corporate strategy and advisory services, which was initially scheduled to expire on January 31, 2014. The Company extended the term of the
consulting  agreement  on  two  occasions,  and  the  consulting  agreement  expired  on  December  31,  2016.  In  connection  with  Mr.  Styslinger’s  services  as  a
consultant, in May 2012, the Company granted Mr. Styslinger stock options for the purchase of 600 shares of common stock, at an exercise price of $1.69 per
share, which vested as to one-third of the shares under the award on February 1, 2013 and in equal monthly installments thereafter for the following two
years. The grant-date fair value of the award totaled $527, which was recorded by the Company as stock-based compensation expense over the vesting period
of the award.

In connection with special dividends declared by the Company’s board of directors in November 2014, June 2016, December 2016, May 2017 and
November 2017 (see Note 10), the board of directors also approved cash payments to be made to holders of the Company’s stock options, SARs and RSUs in
accordance with the provisions of the Company’s equity incentive plans. In connection with the special dividends declared in December 2016 and May 2017,
the Company paid Mr. Styslinger $1,075 as equitable adjustments in the year ended December 31, 2017. The Company made no payments to Mr. Styslinger
as equitable adjustments in the year ended December 31, 2018.

In addition, during both the years ended December 31, 2018 and 2017, the Company recognized general and administrative expenses of $205 for Mr.
Styslinger’s services as a non-employee director. As of December 31, 2018, $14 was due to Mr. Styslinger for his services as a non-employee director. No
amount was due to Mr. Styslinger for his services as a non-employee director as of December 31, 2017.

Employment of Rongke Xie

Rongke  Xie,  who  serves  as  Deputy  General  Manager  of  Guangzhou  Casa  Communication  Technology  LTD  (“Casa  China”),  a  subsidiary  of  the
Company, is the sister of Lucy Xie, the Company’s Senior Vice President of Operations and a member of the Company’s board of directors. Casa China paid
Rongke Xie $143, $160 and $140 in total compensation in the years ended December 31, 2018, 2017 and 2016, respectively, for her services as an employee.

In addition, during the year ended December 31, 2018, the Company granted to Rongke Xie 5 RSUs, which vest in annual installments over a four-
year period. The grant-date fair value of the award totaled $100, which will be recorded as stock-based compensation expense over the vesting period of the
award. During the year ended December 31, 2018, the Company recognized general and administrative expenses of $13 related to this award.

16. Commitments and Contingencies

Operating Leases

The Company leases manufacturing, warehouse and office space in the United States, China, Spain and Ireland under non-cancelable operating leases
that expire in 2021, 2022, 2022 and 2026, respectively. The Ireland lease provides the Company the right to terminate in 2021. Rent expense for the years
ended December 31, 2018, 2017 and 2016 was $1,029, $933 and $572, respectively. Rent expense is recorded on a straight-line basis, and, as a result, as of
December 31, 2018 and 2017, the Company had a deferred rent liability of $184 and $258, respectively, which is included in accrued expenses and other
current liabilities in the accompanying consolidated balance sheets.

Future minimum lease payments under non-cancelable operating leases as of December 31, 2018 were as follows:

Indemnification

The  Company  has,  in  the  ordinary  course  of  business,  agreed  to  defend  and  indemnify  certain  customers  against  third-party  claims  asserting

infringement of certain intellectual property rights, which may include patents, copyrights, trademarks or trade secrets.

As permitted under Delaware law, the Company indemnifies its officers, directors and employees for certain events or occurrences that happen by

reason of their relationship with or position held at the Company.

As of December 31, 2018 and 2017, the Company had not experienced any losses related to these indemnification obligations and no material claims
were  outstanding.  The  Company  does  not  expect  significant  claims  related  to  these  indemnification  obligations  and,  consequently,  concluded  that  the  fair
value of these obligations is negligible, and no related liabilities were recorded in its consolidated financial statements.

Litigation

From time to time, and in the ordinary course of business, the Company may be subject to various claims, charges and litigation. As of December 31,
2018, the Company did not have any pending claims, charges or litigation that it expects would have a material adverse effect on its consolidated financial
position, results of operations or cash flows.

17. Employee Benefit Plan

The Company has a Section 401(k) defined contribution savings plan for its employees. The plan covers substantially all employees in the United
States who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis, subject to
certain  limitations.  Company  contributions  to  the  plan  may  be  made  at  the  discretion  of  the  board  of  directors.  Effective  January  1,  2014,  the  Company
commenced  matching  contributions  in  the  amount  of  50%  of  the  employee’s  contributions  of  up  to  6%  of  eligible  wages.  The  Company  made  matching
contributions to the plan of $1,630, $1,484 and $1,313 in the years ended December 31, 2018, 2017 and 2016, respectively.

On February 19, 2019, the board of directors authorized the repurchase of up to $75,000 of the Company’s common stock under a stock repurchase

program.  The repurchase program may be superseded or discontinued at any time and has no expiration date.

NetComm Wireless

On  February  21,  2019,  the  Company  entered  into  a  definitive  agreement  to  acquire  NetComm  Wireless  Limited  for  cash  consideration  of
approximately $161,000 Australian dollars, or AUD ($115,300 United States dollars, or USD, based on an exchange rate of USD $0.716 per AUD $1.00 on
February 21, 2019). The Company expects the transaction will close in June 2019, subject to closing conditions and required approvals.

Customer Receivable

On February 25, 2019, a customer unexpectedly announced that it had filed for reorganization under Chapter 11 of the U.S. Bankruptcy Code. As of
December 31, 2018, amounts due from the customer totaled $1,255, or 1.5%, of aggregate accounts receivable. For the year ended December 31, 2018, sales
to  the  customer  represented  less  than  0.4%  of  total  revenue.    The  Company  is  assessing  the  bankruptcy  filing  and  may  need  to  write  off  this  receivable
balance in a future period if the receivable is deemed uncollectible.

Item 9A. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated 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, as amended, or the Exchange Act), as of
the end of the period covered by this Annual Report on Form 10-K. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-
15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a
company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in
the Securities and Exchange Commission’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed
to  ensure  that  information  required  to  be  disclosed  by  a  company  in  the  reports  that  it  files  or  submits  under  the  Exchange  Act  is  accumulated  and
communicated to the company’s management, including its principal executive and principal financial officers, or persons performing similar functions, as
appropriate  to  allow  timely  decisions  regarding  required  disclosure.  Our  management  recognizes  that  any  controls  and  procedures,  no  matter  how  well
designed  and  operated,  can  provide  only  reasonable  assurance  of  achieving  their  objectives  and  our  management  necessarily  applies  its  judgment  in
evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of the end of
the period covered by this Annual Report on Form 10-K, our principal executive officer and principal financial officer have concluded that as of such date,
our disclosure controls and procedures were effective.

Management's Report on Internal Control Over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Internal  control  over  financial
reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Exchange Act as a process designed by, or under the supervision of, the company’s
principal executive and principal financial officers and effected by the company’s board of directors, management and other personnel, 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 and includes those policies and procedures that:

•

•

•

Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of the assets
of the company;

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,

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. 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.

Our management assessed the effectiveness of our internal control over financial reporting as of December 31, 2018. In making this assessment, our
management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated
2013  Framework.    Based  on  this  assessment,  our  management  concluded  that,  as  of  December  31,  2018,  our  internal  control  over  financial  reporting  is
effective based on those criteria.

This  Annual  Report  on  Form  10-K  does  not  include  an  attestation  report  of  our  independent  registered  public  accounting  firm  due  to  a  transition

period established by rules of the SEC for “emerging growth companies”.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during our most recently completed fiscal quarter that have materially affected,

or are reasonably likely to materially affect, our internal control over financial reporting.

withholdings as required by law.  Such salary may be adjusted from time to time in accordance with normal business practice and in the sole
discretion of the Company.

In 2019, you will be eligible for an annual performance incentive bonus. Your annual on-target incentive will be 1.5x your base annual salary
(equivalent to $600,000.00), if all targets are achieved and prorated based on your date of hire, less applicable taxes, deductions, and
withholdings. Your actual bonus payout will depend upon Casa Systems financial performance results and the assessment of your individual

You may participate in any and all bonus and benefit programs that the Company establishes and makes available to its employees from time to

Starting in 2019, and subject to the approval of the Board of Directors of the Company, the Company will grant to you an annual award of

or without cause, at any time, with or without notice.  Similarly, nothing in this letter shall be construed as an agreement, either express or
implied, to pay you any compensation or grant you any benefit beyond the end of your employment with the Company.
