Our Vision

PART I

Our products help our customers provide and manage broadband connectivity. We believe consumers and enterprises should be able to enjoy ultra-fast
speeds and enhanced digital content experiences through their phones, tablets, computers, TVs and other connected devices at home or on the go. We believe
that connectivity should be ubiquitous and seamless; it should not matter whether the user is accessing the Internet through wireless or fixed connections, and
it should not matter whether that service is being provided by a cable operator, fixed telecom carrier or wireless services provider. Our innovative, software-
centric products are designed to help achieve this vision.

Overview

We  offer  solutions  for  next-generation  centralized,  distributed  and  virtualized  architectures  for  cable  broadband,  fixed-line  broadband  and  wireless
networks. Our innovative 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. Our solutions include a suite of software-centric
infrastructure solutions that allow cable service providers to deliver voice, video and data services over a single platform at multi-gigabit speeds.

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.

We have created a software-centric, multi-service portfolio 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 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. 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.

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  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.

Our solutions are commercially deployed in over 75 countries by more than 450 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 and
Mediacom in North America; Televisa/IZZI Mexico, Megacable Mexico and Claro Telmex Colombia in Latin America; Liberty Global, Vodafone and DNA
Oyj in Europe; and Jupiter Communications and Beijing Gehua CATV Networks in Asia-Pacific.

We have achieved significant growth in revenue and profitability. Our revenue for the years ended December 31, 2017, 2016, 2015 and 2014 was
$351.6 million, $316.1 million, $272.5 million and $211.3 million, respectively, representing a compound annual growth rate of 18%. Our net income for the
years ended December 31, 2017, 2016, 2015 and 2014 was $88.5 million, $88.7 million, $67.9 million and $59.7 million, respectively. As of December 31,
2017, 2016 and 2015, our total assets were $469.7 million, $583.0 million and $283.1 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.

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;

the backhaul demand by 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 a June 2017 Cisco Systems Visual Networking Index report, global IP traffic per month is forecasted to grow from 96 exabytes in 2016
(1 exabyte = 1,000,000,000 GB) to 278 exabytes in 2021, representing a 24% compound annual growth rate in global IP traffic; global IP traffic per capita is
expected to increase from 13GB in 2016 to 35GB in 2021; and the number of connected devices is forecast to be three times the global population by 2021.

Competition Fueled by Increasing Breadth of Service Offerings

Consumers  and  enterprises  enjoy  increased  choice  among  broadband  service  providers,  including  cable  service  providers  such  as  Charter  and
Comcast, diversified telecommunications companies such as AT&T and Verizon, and mobile-only network operators such as Sprint and T-Mobile. As a result,
broadband  service  providers  are  facing  increasing  pressure  to  develop  differentiated  service  offerings  with  higher  levels  of  performance  at  lower  cost  to
consumers  and  enterprises.  They  are  also  under  competitive  pressure  to  offer  a  wider  range  of  services,  from  Internet  access,  television,  telephone  and
wireless services to additional services such as voice over Wi-Fi, video calling and, in general, smart Internet and security-related services. Moreover, the
increasing  popularity  of  over-the-top  services  puts  additional  pressure  on  the  traditional  video  business  of  broadband  service  providers.  In  this  new
environment, fixed service providers have deployed fiber and Wi-Fi networks and have been exploring ways to provide mobile service offerings.

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 lack of interoperability
of these separate networks has resulted in increasing network complexity and inefficient parallel network infrastructure.

Need to Control Operating and Capital Expenditures

The operation of network infrastructure is space, power and personnel intensive. In addition, the lack of interoperability between networks means that
broadband  service  providers  cannot  optimize  bandwidth  usage  by  allocating  traffic  from  networks  experiencing  high  demand  to  those  experiencing  low
demand, which can result in unused capacity and an unsatisfactory user experience.

Hardware-centric networks can also be expensive to update or replace. With frequent technology shifts and introductions of new service offerings,
competition  in  the  broadband  industry  is  constantly  changing.  To  remain  competitive,  service  providers  are  regularly  required  to  incur  significant  capital
expenditures to upgrade existing equipment.

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.

Densification

Increasing demand for bandwidth and user expectations for ubiquitous and seamless connectivity require, among other things, the addition of more
end  points  for  users  to  access  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. This results in the deployment of additional hardware, such as access aggregation nodes, small cells and related gateways.

Network Convergence

Many  traditional  service  providers  have  historically  either  operated  just  one  network  type  or  operated  fixed  and  wireless  networks  as  separate
businesses.  However,  more  and  more  service  providers  that  may  have  started  out  providing  just  fixed  or  wireless  services  are  recognizing  the  benefits,
especially those associated with quality of experience, of being able to provide both services to their subscribers. For example, cable service providers in the
United  States  have  formed  a  joint  consortium,  Cable  WiFi,  that  provides  Wi-Fi  access  to  broadband  cable  subscribers  at  over  500,000  access  points.
Continued acquisition activity, such as Altice’s acquisitions of Cablevision and SuddenLink and Vodafone’s acquisition of Kabel Deutschland, has accelerated
fixed and wireless convergence. This consolidation trend has caused a heightened focus on the economics of maintaining two networks. Broadband service
providers are seeking to integrate their separate delivery modes with all-IP architectures, shared transport and a common suite of software-centric core and
access network functions.

Virtualization

Service providers are rethinking traditional network architectures and moving toward more software-driven architectures. The use of software permits
a  fundamental  change  in  the  way  broadband  service  providers  deliver  critical  network  functions.  Software-enabled  architectures  that  are  decoupled  from
underlying hardware allow for increased efficiencies, upgradability, configuration flexibility, service agility and scalability not feasible with hardware-centric
approaches.

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  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

6

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.

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. Similarly, 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. For
example, our solutions permit our customers to transition from Data Over Cable Service Interface Specification, or DOCSIS, 3.0 to DOCSIS 3.1 with less
network downtime and fewer hardware replacements that result in lower costs than those of our competitors.

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.

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;

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

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

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

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

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,  2017,  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 75 countries by more than 450 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  grew  from  6%  in  2012  to  21%  in  2014  to  27%  in  2016.  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 30 trials with over 25 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. As fixed and wireless networks continue to converge, we
believe there is an opportunity for us to take advantage of this fundamental shift. 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.

According to S&P Global Market Intelligence, the CCAP market (including both centralized and distributed solutions) is projected to grow from $2.0

billion in 2017 to $2.7 billion in 2021, representing a 6% compound annual growth rate. This market currently accounts for the majority of our revenue.

•

In addition, we believe the global market for our small cell, evolved packet core and PON solutions will grow from $7.2 billion in 2017 to $16.0
billion  2021,  representing  a  22%  compound  annual  growth  rate.    Our  small  cell-related  solutions  have  been  purchased  by  several  customers,
including Tier 1 mobile operators, and our small cell-related solutions, components of our evolved packet core application 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 40 customers in 2017.

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. We have invested in developing a

virtualized platform that allows us to rapidly provide new applications and services to our customers.

Leverage Our Core Technology for the Cable Industry into Adjacent Wireless 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 30 trials with over 25 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.

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

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

10

 
 
 
 
 
 
 
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 remotely installed 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  Apex  small  cell  solution  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. It allows a number
of  connectivity  options  including  LTE  and  3G.  The  Apex  small  cell  solution  allows  broadband  service  providers  to  more  cost-effectively
densify cellular networks.

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.

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.

11

 
 
 
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 Core. Enables subscriber management, session management and authentication, security and data exchange between the core
network and subscribers.

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 450 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 Telmex Colombia;

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

in Asia-Pacific: Jupiter Communications and 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

12

 
 
 
 
 
 
 
 
 
 
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 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, 2017, our research and development organization consisted of 399 employees worldwide, including both software and hardware
engineers. Our research and development expense totaled $60.7 million, $49.2 million and $37.2 million for the years ended December 31, 2017, 2016 and
2015, respectively. We plan to continue to devote substantial resources to our research and development activities.

13

 
 
 
 
 
 
 
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, 2017 and 2016, we had
backlog  of  $40.0  million  and  $24.5  million,  respectively. The  increase  in  backlog  over  that  period  was  due  principally  to  the  timing  of  shipments  of  our
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,  2017,  we  expect  that  approximately  $36.8  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.

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, 2017, we employed 680 full-time employees, of which 359 were located in the United States and 321 were located outside the
United States. Our workforce as of December 31, 2017, consisted of 399 employees in engineering and research and development, 122 employees in sales
and  marketing,  65  employees  in  general  and  administrative,  59  employees  in  manufacturing  and  35  employees  in  services  and  support.  None  of  our
employees are

14

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,

15

 
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, which purchased Time
Warner  Cable  in  2016,  accounted  for  37%,  23%  and  14%  of  our  revenue  for  the  years  ended  December  31,  2017,  2016  and  2015,  respectively;  sales  to
Liberty Global accounted for 11%, 10% and 17% of our revenue for the years ended December 31, 2017, 2016 and 2015, respectively; and sales to Rogers
accounted for 19% of our revenue for the year ended December 31, 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. 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.

16

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 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,  2017,  2016  and  2015,  our
research and development expenses were $60.7 million, or approximately 17.3% of our revenue, $49.2 million, or approximately 15.6% of our revenue, and
$37.2 million, or approximately 13.6% 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  2017  to  2018.  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

17

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,  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;

18

 
 
 
 
 
 
 
 
 
 
 
 
 
•

•

•

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  uncollectable  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.

19

 
 
 
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 the 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.

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

•

•

•

•

•

•

•

•

•

•

•

•

•

•

•

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;

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

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 FCPA, privacy and data protection laws and regulations and any trade regulations ensuring fair trade practices; and

20

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
•

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 U.S. Foreign Corrupt Practices Act of 1977, as amended.

We are subject to anti-corruption laws such as the U.S. Foreign Corrupt Practices Act of 1977, as amended, or 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.

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

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 recently discovered 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 have voluntarily disclosed
the potential technical violations to BIS, and, although BIS may impose a penalty, we do not expect any such penalty to be material to our business, financial
condition, results of operations and prospects.

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

21

 
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 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. We may not
achieve similar revenue growth rates 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  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

22

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  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.

23

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.

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. For example, our revenue increased from $272.5 million for the year ended December 31, 2015 to
$316.1 million for the year ended December 31, 2016 and to $351.6 million for the year ended December 31, 2017. To handle this growth and increase in
demand, we have significantly expanded our headcount, from 481 as of December 31, 2015 to 604 as of December 31, 2016 and to 680 as of December 31,
2017, 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

24

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 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  94  as  of  December  31,  2015  to  114  as  of  December  31,  2016  and  to  122  as  of
December 31, 2017. 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.

25

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.

26

 
 
 
 
 
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.

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 country 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.

27

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 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.

28

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 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.

29

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, 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,

30

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.  We  do  not  have
experience in making investments in other companies nor have we made any 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 investment or acquisition candidates, and we may not be able to complete such investments or acquisitions on favorable terms, if at all. If we do
complete 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,  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  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.  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.

31

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. We are unable to determine at this time what effect such changes, or others that may be
enacted in the future, may have on our business.  Due to our existing, and anticipated expansion of, our international business activities, any changes in the
U.S. or foreign taxation of such activities 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 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.

32

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. Our indebtedness increases the possibility that 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.

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;

33

 
 
 
 
 
 
 
•

•

•

•

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;

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:

•

•

•

•

•

•

•

•

•

•

•

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

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

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

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.

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.

34

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.

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 February 28, 2018, our directors and executive officers and their affiliates beneficially owned, in the aggregate, approximately 74.3% of our
outstanding  common  stock,  as  disclosed  in  the  beneficial  ownership  table  included  in  Item  12  of  this  Annual  Report  on  Form  10-K.  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  substantial  number  of  shares  of  our  common  stock  in  the  public  market  could  occur  at  any  time  after  the  expiration  of  the  lock-up
agreements on June 13, 2018, which were executed in connection with the initial public offering of our common stock. 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. As of February 28, 2018, 75,030,281
shares,  or  92.0%  of  our  outstanding  shares,  are  restricted  as  a  result  of  securities  laws  or  lock-up  agreements  but  will  be  able  to  be  sold,  subject  to  any
applicable volume limitations under federal securities laws with respect to affiliate sales in the near future.

In addition, as of February 28, 2018, there were 15,533,195 shares subject to outstanding options, 404,546 shares subject to outstanding restricted
stock unit awards, or RSUs, and an additional 9,362,901 shares reserved for future issuance under our equity incentive plans that will become eligible for sale
in the public market to the extent permitted by any applicable vesting requirements, lock-up agreements and Rules 144 and 701 under the Securities Act of
1933, as amended. Moreover, holders of an aggregate of approximately 43,274,870 shares of our common stock as of February 28, 2018, will have rights,
subject to some 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. We also intend to register all shares of common stock that we may issue under our equity incentive plans. Once we
register  these  shares,  they  can  be  freely  sold  in  the  public  market  upon  issuance,  subject  to  the  lock-up  agreements  and  the  restrictions  imposed  on  our
affiliates under Rule 144.

35

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. 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.

36

 
 
 
 
 
 
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. In this Annual
Report on Form 10-K, we have not included all of the executive compensation related information that would be required if we were not an emerging growth
company. 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 have elected to rely on certain phase-in provisions of the Nasdaq Stock Market rules, and, as a result, we will not immediately be subject to certain
corporate governance requirements otherwise required of Nasdaq-listed companies.

We are currently relying on the phase-in provisions of the Nasdaq rules for certain corporate governance requirements, including the requirements that

we have:

•

•

•

a majority of independent directors on our board of directors;

an audit committee that is composed entirely of independent directors; and

a compensation committee that is composed entirely of independent directors.

Under the phase-in provisions of the Nasdaq rules, a majority of the members of our board of directors must be independent within one year of the
date  of  our  initial  public  offering,  and  we  must  comply  with  the  following  independence  requirements  with  respect  to  our  audit  committee  and  our
compensation committee: (1) one independent member of each committee beginning at the time of our initial public offering, (2) a majority of independent
members of each committee within 90 days following the date of our initial public offering and (3) all independent members of each committee within one
year of the date of our initial public offering. As of February 28, 2018, only two members of our board of directors had been determined to be independent,
only one member of our audit committee had been determined to be independent and only one member of our compensation committee had been determined
to be independent. During the phase-in periods, our stockholders will not have the same protections afforded to stockholders of companies that comply with
Nasdaq’s independence requirements without reliance on the phase-in periods. We will be required to recruit new directors in order to comply with Nasdaq’s
independence requirements, and the resultant changes in our board and committee membership may

37

 
 
 
influence our future corporate strategy and operating philosophies and may result in deviations from our current strategy. Additionally, if, during the phase-in
periods, we are unable to recruit a sufficient number of new directors who qualify as independent or otherwise comply with Nasdaq rules, we may be subject
to delisting by Nasdaq.

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.

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 incremental 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  incremental  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.

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, 2017. As of December 31, 2017,
outstanding borrowings under the mortgage loan were $7.3 million.

We  lease  additional  facilities  in  Lawrence,  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 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.

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. As a result, we have only set forth quarterly information with respect to the high and low prices for our common stock for the
period following our IPO.  The following table sets forth on a per share basis, for the period indicated, the high and low sale prices of our common stock as
reported by the Nasdaq Global Select Market.

As of February 28, 2018, there were 65 holders of record of our common stock. Because many of our shares are held by brokers and other institution

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

Dividend Policy

Prior to our initial public offering, we declared special dividends in November 2014, June 2016, December 2016, May 2017 and November 2017. The
November 2014 special dividend totaled $27.6 million in cash payments to our stockholders. In connection with the November 2014 special dividend, our
board of directors also approved cash payments totaling $2.4 million to be made to holders of our stock options and stock appreciation rights as equitable
adjustments to the holders of such instruments in accordance with the provisions of our equity incentive plans. The June 2016 special dividend totaled $43.1
million in cash payments to our stockholders. In connection with the June 2016 special dividend, our board of directors also approved cash payments totaling
$6.9 million to be made to holders of our stock options, stock appreciation rights and restricted stock units as equitable adjustments to the holders of such
instruments in accordance with the provisions of our equity incentive plans. The December 2016 special dividend totaled $171.4 million in cash payments to
our stockholders. In connection with the December 2016 special dividend, our board of directors also approved cash payments totaling $28.6 million to be
made  to  holders  of  our  stock  options,  stock  appreciation  rights  and  restricted  stock  units  as  equitable  adjustments  to  the  holders  of  such  instruments  in
accordance with the provisions of our equity incentive plans. The May 2017 special dividend totaled $87.1 million in cash payments to our stockholders. In
connection with the May 2017 special dividend, our board of directors also approved cash payments totaling $12.9 million to be made to holders of our stock
options, stock appreciation rights and restricted stock units as equitable adjustments to the holders of such instruments in accordance with the provisions of
our  equity  incentive  plans.  The  November  2017  special  dividend  totaled  $43.0  million  in  cash  payments  to  our  stockholders.  In  connection  with  the
November 2017 special dividend, our board of directors also approved cash payments totaling $7.0 million to be made to holders of our stock options, stock
appreciation  rights  and  restricted  stock  units  as  equitable  adjustments  to  the  holders  of  such  instruments  in  accordance  with  the  provisions  of  our  equity
incentive plans.

Although we have declared and paid the special dividends described above, we do not anticipate declaring cash dividends in the foreseeable future.
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.

Under  our  2011  Stock  Incentive  Plan,  we  granted  stock  options  to  purchase  an  aggregate  of  1,260,920  shares  of  our  common  stock  to
employees, directors and consultants, with exercise prices ranging from $11.25 to $12.24 per share, and we issued 76,905 shares of common
stock pursuant to the exercise of stock options for aggregate consideration of $247,810.

Under our 2011 Stock Incentive Plan, we granted an aggregate of 191,090 restricted stock units to be settled in shares of our common stock to
certain of our employees and we issued 418,330 shares of common stock upon the vesting of restricted stock units.

Under  our  2011  Stock  Incentive  Plan,  we  granted  an  aggregate  of  110,000  stock  appreciation  rights  to  be  settled  in  cash  to  certain  of  our

exercise price of $0.10 per share, for aggregate consideration of $5,417.

None of the foregoing transactions involved any underwriters, underwriting discounts or commissions, or any public offering. The stock options and
the common stock issued upon the exercise of such options, and the restricted stock units and the common stock issued upon the vesting of such restricted

2003 Stock Incentive Plan in reliance on the exemption provided by Rule 701 promulgated under the Securities Act. Each of the recipients of securities in
these transactions had adequate access, through employment, business or other relationships, to information about us. The sales of these securities were made
without any general solicitation or advertising.

Issuer Repurchases of Equity Securities

Under our equity incentive plans, certain participants may exercise options prior to vesting, subject to a right of a repurchase by us. During the fiscal
year ended December 31, 2017 we made no repurchases of unvested shares of our common stock made pursuant to our equity incentive plans as a result of
our exercising our rights nor pursuant to any publicly announced plan or program.

Securities Authorized for Issuance Under Equity Compensation Plans

The information required by this item with respect to our equity compensation plans is incorporated by reference to the section entitled “Securities

authorized for issuance under equity compensation plans” in Item 12 of Part III of this Annual Report on Form 10-K.

Use of Proceeds

On  December  19,  2017,  we  closed  our  initial  public  offering  of  6,900,000  shares  of  our  common  stock,  including  900,000  shares  of  our  common
stock  pursuant  to  the  full  exercise  by  the  underwriters  of  an  option  to  purchase  additional  shares,  at  a  public  offering  price  of  $13.00  per  share  for  an
aggregate offering of approximately $89.7 million.  The offer and sale of all of the shares in the offering were registered under the Securities Act pursuant to a
registration  statement  on  Form  S-1  (File  No.  333-221658),  which  was  declared  effective  by  the  Securities  and  Exchange  Commission,  or  the  SEC,  on
December 14, 2017.  Morgan Stanley & Co. LLC and Barclays Capital Inc. acted as joint book-running managers for the offering, with Raymond James &
Associates, Inc., Stifel, Nicolaus & Company, Incorporated, Macquarie Capital (USA) Inc., Northland Securities, Inc. and William Blair & Company, L.L.C.
acting as co-managers.  The offering commenced on December 14, 2017 and did not terminate until all of the shares offered had been sold.  

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.

41

 
 
 
 
 
 
 
As of December 31, 2017, 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.  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).

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

We  offer  solutions  for  next-generation  centralized,  distributed  and  virtualized  architectures  in  cable  broadband,  fixed-line  broadband  and  wireless
networks. Our innovative 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. Our solutions include a suite of software-centric
infrastructure solutions that allow cable service providers to deliver voice, video and data services over a single platform at multi-gigabit speeds.  

We have created a software-centric, multi-service portfolio 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 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. 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.

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  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  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.

We have achieved significant growth in revenue and profitability. Our revenue has increased from $211.3 million in 2014 to $351.6 million in 2017,
representing  a  compound  annual  growth  rate  of  18%.  Our  income  from  operations  has  increased  from  $89.0  million  in  2014  to  $136.2  million  in  2017,
representing  a  compound  annual  growth  rate  of  15%.  Our  solutions  are  commercially  deployed  in  more  than  75  countries  by  more  than  450  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. The majority of our product revenue is derived from sales of our broadband products,
particularly our C100G converged cable access platform, or CCAP, solution. 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.

45

Since shipping our first products in 2005, our cumulative end-customer base has grown significantly. 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 75 countries by more than 450 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, 2017, 2016 and 2015, sales to existing customers
represented  97%,  74%  and  63%  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 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.
We have also developed solutions for telecommunications service providers. 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  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 continue to increase in absolute dollars while remaining relatively stable as a percentage of
revenue  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 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%  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. Given the significant complexity of the TCJA, anticipated guidance from the U.S. Treasury Department about
implementing the TCJA and the potential for additional guidance from the Securities and Exchange Commission, or the SEC, or the Financial Accounting
Standards Board, or the FASB, related to the TCJA or additional information becoming available, our provisional income tax charge may be adjusted during
2018 and is expected to be finalized no later than the fourth quarter of 2018. Other provisions of the TCJA that impact future tax years are still being assessed.

In the third quarter of 2016, we began the process of restructuring our international operations, which over time is expected to reduce our effective tax
rate;  however,  due  to  the  timing  of  this  restructuring  program,  the  impact  on  our  effective  tax  rate  in  2016  was  not  fully  realized.  In  addition,  our  2016
effective tax rate and provision for income taxes reflected a non-recurring tax benefit for equitable adjustment payments to holders of our stock-based awards
in connection with dividends declared by our board of directors. Our 2017 effective tax rate reflects the benefit of our international restructuring, and charges
related  to  the  TCJA,  as  well  as  a  non-recurring  tax  benefit  for  equitable  adjustment  payments  to  holders  of  our  stock  based  awards  in  connection  with
dividends declared by our board of directors. We expect that the favorable impact of the restructuring of our international operations on our effective tax rates
will continue in future periods, subject to period to period variability related to the geographic distribution of earnings in foreign jurisdictions with statutory
tax rates different from those in the United States.

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

The increase in service revenue was primarily due to a $3.8 million increase in maintenance and support services revenue due to an increase in our
installed base of customers through the addition of new customers and from customers renewing their maintenance and support service contracts, partially
offset by a $1.1 million decrease in professional services revenue due to a decrease in customer projects requiring our assistance.

The decrease in cost of product revenue was primarily due to a decrease in the proportion of our revenue derived from our hardware-based broadband

products.

The  decrease  in  cost  of  service  revenue  was  primarily  due  to  a  $2.1  million  decrease  in  subcontracted  professional  services  and  a  $1.6  million
decrease in personnel-related costs as a result of the transfer of certain personnel from our service and support department to our research and development
department.

The change from a net other income of $0.9 million to a net other expense of $13.4 million was primarily due to a $16.6 million increase in interest
expense attributable to our term loan facility entered into in December 2016, partially offset by a $1.2 million increase in interest income due to an increase in
interest rates and an increase in our portfolio of cash equivalents and a $1.2 million increase in foreign currency gains due to appreciation of the Euro and the
impact thereof on our foreign-denominated cash and receivables.

The increase in product revenue was due to an increase in sales of our software-centric broadband products in North America primarily due to an
increase  of  $74.2  million  in  sales  to  new  customers,  which  predominantly  deployed  our  CCAP  solution  that  includes  DOCSIS  3.1  capabilities,  and  an
increase of $45.7 million in sales of our CCAP solutions to existing customers to increase the proportion of their networks using our products to provide their
subscribers with greater bandwidth capacity through capacity expansions. These increases were partially offset by an aggregate decrease of $88.3 million in
product sales in all other regions resulting primarily from decreases in purchases by customers in those regions of capacity expansions from us, which we
believe was primarily due to the timing of customer expenditures on network upgrades.

The increase in service revenue was primarily due to a $9.3 million increase in maintenance and support services revenue due to an increase in our
installed base of customers through the addition of new customers and from customers renewing their maintenance and support service contracts as well as a
$2.8 million increase in professional services revenue related to customer installations in North America to deploy our DOCSIS 3.1 capabilities.

The 9.8% decrease in our effective tax rate primarily resulted from the tax benefits from certain employee stock-based compensation transactions,
including equitable adjustment payments to holders of our stock-based awards, during the year ended December 31, 2016 related to our adoption, effective as
of January 1, 2016, of a new share-based payment accounting standard. In particular, the tax benefit of equitable adjustment payments in 2016 contributed to
a 7.0% non-recurring reduction in our effective tax rate. The decrease in our effective tax rate was also due in part to an increase in the benefit of the foreign
tax rate differential, reflecting the partial effect of a process we began in the third quarter of 2016 to restructure our international operations.

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.
The following tables set forth our cash, cash equivalents and marketable securities and working capital as of December 31, 2017, 2016 and 2015 as well as
our net cash flows for the years ended December 31, 2017, 2016 and 2015:

As  of  December  31,  2017,  we  had  cash  and  cash  equivalents  of  $260.8  million  and  net  accounts  receivable  of  $127.3  million.  We  maintain  a
$25.0 million revolving credit facility under which $24.0 million was available and $1.0 million was used as collateral for a stand-by letter of credit as of
December 31, 2017.

Of our total cash and cash equivalents of $260.8 million as of December 31, 2017, $31.3 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. We are still evaluating whether to
change our indefinite reinvestment assertion in light of the TCJA and consider that conclusion to be incomplete under guidance issued by the SEC. If we
subsequently change our assertion during the measurement period, such changes will be accounted for through an adjustment to the provisional income tax
charge during 2018, which is expected to be finalized no later than the fourth quarter of 2018.

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, 2017, 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 $206.4 million, $137.4 million and $0.3 million in the years ended December 31,
2017, 2016 and 2015, respectively. The equitable adjustment payments totaled $40.2 million, $4.9 million and $0.4 million in the years ended December 31,
2017, 2016 and 2015, respectively. As of December 31, 2017, there were $9.8 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.

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.

During  the  year  ended  December  31,  2015,  cash  provided  by  operating  activities  was  $24.6  million,  primarily  resulting  from  our  net  income  of
$67.9  million  and  net  non-cash  charges  of  $12.7  million,  both  partially  offset  by  net  cash  used  by  changes  in  our  operating  assets  and  liabilities  of
$56.0  million.  The  net  cash  used  by  changes  in  our  operating  assets  and  liabilities  during  the  year  ended  December  31,  2015  was  primarily  due  to  a
$28.6  million  decrease  in  deferred  revenue  primarily  due  to  recognition  of  $23.1  million  of  revenue  upon  the  product  acceptance  by  a  new  customer  in
Europe that deployed our CCAP solution, a $10.8 million decrease in accrued income taxes due to the timing of tax payments, a $17.4 million increase in
inventory  for  anticipated  growth  in  our  business  and  a  $9.7  million  increase  in  accounts  receivable  due  to  an  increase  in  sales  and  timing  of  the  related
collections. These uses of cash were partially offset by a $2.7 million increase in accounts payable primarily attributable to the timing of our payments for the
purchases  of  inventory  and  an  $8.0  million  increase  in  accrued  expenses  and  other  current  liabilities,  which  included  an  increase  of  $3.4  million  for
personnel-related accrued liabilities, such as accrued salaries and bonuses, due to the growth in headcount.

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.  Our  investing  activities  in  2015  also
included the purchase of our corporate offices.

58

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.

Net cash used in investing activities during the year ended December 31, 2015 was $15.5 million for purchases of property and equipment, consisting

primarily of the purchase of and improvements to our corporate offices totaling $10.4 million during that period.

Financing Activities

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.

Net  cash  provided  by  financing  activities  during  the  year  ended  December  31,  2015  was  $7.3  million  and  consisted  primarily  of  proceeds  of

$7.9 million from the commercial mortgage on our corporate offices, partially offset by $0.7 million of dividend and equitable adjustment payments.

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, 2017 and 2016. As of December 31, 2017 and
2016, the outstanding principal amount under the mortgage loan was $7.3 million and $7.6 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, 2017 and 2016, we had borrowings of $297.0 million and $300.0 million, respectively, outstanding under the term loan facility
and we did not have any outstanding borrowings under the revolving credit facility; however, we had used $1.0 million under the revolving credit facility for
a stand-by letter of credit that serves 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.  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.

59

 
 
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.

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, 2017, the interest rate on our borrowings under the term loan facility
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. As of December 31, 2016, the interest rate on the term loans was 5.00% per annum, which was based on a one-month Eurodollar rate at the applicable floor
of 1.00% 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, 2017 and 2016. As of December 31, 2017 and 2016, 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.

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 5.69% per annum, which was
the interest rate in effect as of December 31, 2017.
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, 2019, 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 $7.7 million of long term taxes payable recorded as part of a provisional charge in the fourth quarter
of 2017 for the mandatory deemed repatriation tax on undistributed earnings of foreign subsidiaries under the TCJA. The deemed repatriation was estimated
based on our initial analysis in accordance with ASC Topic 740, Income Taxes, and Staff Accounting Bulletin 118 and is expected to be paid over the next
eight years. Given the significant complexity of the TCJA, anticipated guidance from the U.S. Treasury Department about implementing the TCJA and the
potential for additional guidance from the SEC or the FASB related to the TCJA or additional information becoming available, our provisional charge may be
adjusted during 2018 and is expected to be finalized no later than the fourth quarter of 2018.

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.

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,

62

 
 
 
 
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.

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.

63

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 until the credits have been applied by the
customer against accounts receivable due to us or the credits expire.

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, 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. As of December 31, 2016, we had foreign currency forward contracts outstanding with
notional amounts totaling 11.2 million euros maturing in 2017. There were no outstanding derivative instruments as of December 31, 2015.

64

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, 2016, we recorded an asset of $0.1 million and as of December 31, 2017 and 2016, we
recorded a liability of $0.2 million and $0.1 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.

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%  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. Given the significant complexity of the
TCJA, anticipated guidance from the U.S. Treasury Department about implementing the TCJA and the potential for additional guidance from the SEC or the
FASB related to the TCJA or additional information becoming available, the provisional income tax charge may be adjusted during 2018 and is expected to
be finalized no later than the fourth quarter of 2018. Other provisions of the TCJA that impact future tax years are still being assessed.

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.

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

65

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  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
cancelled, 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 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, 2017, 2016 and 2015, 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, 2017, 2016 and 2015, we incurred foreign currency transaction gains (losses) of $0.9 million, $(0.3) million and $(3.0) million, respectively,
primarily  related  to  unrealized  and  realized  foreign  currency  losses  for  accounts  receivables  denominated  in  foreign  currencies.  These  foreign  currency
transaction 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, 2017 that mature in the first and second quarter of 2018, 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, 2017 consisted of cash maintained in FDIC-insured operating accounts as well as investments in
money  market  mutual  funds,  commercial  paper  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.

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

67

(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,  2017,  we  had  borrowings  of  $297.0  million  outstanding  under  the  term  loan  facility,  bearing  interest  at  a  rate  of  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.
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, 2017, an increase of 10%, or approximately 17 basis points, in the three-month Eurodollar rate as of December 31, 2017 would cause pre-tax decreases to
our  earnings  and  cash  flows  of  approximately  $0.5  million  per  year,  assuming  that  such  rate  were  to  remain  in  effect  for  a  year.  A  decrease  of  10%,  or
approximately 17 basis points, in the three-month Eurodollar rate as of December 31, 2017 would cause pre-tax increases to our earnings and cash flows of
approximately $0.5 million, assuming that such rate were to remain in effect for a year.

As of December 31, 2017, 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 Shareholders of Casa Systems, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Casa Systems, Inc. and its subsidiaries as of December 31, 2017 and 2016 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, 2017 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, 2017 and
2016, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2017 in conformity with accounting
principles generally accepted in the United States of America.

Change in Accounting Principle

As discussed in Note 8 to the consolidated financial statements, the Company changed the manner in which it accounts for windfall tax benefits as of January
1, 2016.

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.

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
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’s solutions include a suite of
software-centric infrastructure solutions that allow cable service providers to deliver voice, video and data services over a single platform at multi-gigabit
speeds.

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.

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 of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have
been eliminated in consolidation.

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.

75

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 Equivalents

Cash equivalents include all highly liquid investments maturing within three months from the date of purchase. As of December 31, 2017 and 2016,

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

Marketable Securities

Marketable securities with original maturities of greater than three months and remaining maturities of less than one year from the balance sheet date
are classified as current assets. Marketable securities with remaining maturities of greater than one year from the balance sheet date are classified as non-
current assets.

The  Company  classifies  all  of  its  marketable  securities  as  available-for-sale  securities.  The  Company’s  marketable  securities  are  measured  and
reported  at  fair  value.  Unrealized  gains  and  losses  are  reported  as  a  separate  component  of  stockholders’  equity  (deficit).  The  cost  of  securities  sold  is
determined  on  a  specific  identification  basis,  and  realized  gains  and  losses  are  included  in  other  income  (expense)  within  the  consolidated  statement  of
operations  and  comprehensive  income.  If  any  adjustment  to  fair  value  reflects  a  decline  in  the  value  of  the  investment,  the  Company  considers  available
evidence to evaluate the extent to which the decline is “other than temporary” and reduces the investment to fair value through a charge to the consolidated
statement  of  operations  and  comprehensive  income.  The  Company  did  not  have  any  marketable  securities  outstanding  as  of  December  31,  2017.  As  of
December 31, 2016, the Company’s marketable securities consisted of investments in certificates of deposit.

Accounts Receivable

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 (see—“Revenue Recognition—Deferred Revenue”).

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, 2017, 2016 and 2015 is as follows:

As of December 31, 2017 and 2016, 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, 2017, 2016 and 2015, 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

Estimated Useful Life
3 years
Shorter of lease term or 7 years
7 years

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, 2017, 2016 and 2015.  

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 $2,384 and $517 were paid
during the years ended December 31, 2017 and 2016, respectively.

Concentration of Risks

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, marketable
securities  and  accounts  receivable.  Cash  and  cash  equivalents  and  marketable  securities  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, cash equivalents and marketable securities and does not believe that it is subject to unusual credit
risk beyond the normal credit risk associated with commercial banking relationships.

Customer B is 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, 2017, 2016 and 2015 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.

80

 
 
 
 
 
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

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.

81

 
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. The amounts of deferred revenue recorded in the consolidated balance sheet as of December 31, 2016
included amounts deferred for trade-in rights of $8,477. As of December 31, 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.

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 stock appreciation right 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

82

 
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.

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 $886, $(328) and $(3,020) for the years ended December 31, 2017, 2016 and 2015, 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

83

 
 
 
 
 
 
offsetting amount of deferred revenue has been recorded. The carrying values of the Company’s debt obligations (see Note 9) as of December 31, 2017 and
2016 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.

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 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%  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. Given the
significant complexity of the TCJA, anticipated guidance from the U.S. Treasury Department about implementing the TCJA and the potential for additional
guidance from the Securities and Exchange Commission (“SEC”) or the Financial Accounting Standards Board (“FASB”) related to the TCJA or additional
information becoming available, the Company’s provisional income tax charge may be adjusted during 2018 and is expected to be finalized no later than the
fourth quarter of 2018. Other provisions of the TCJA that impact future tax years are still being assessed.

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.

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 July 2015, the FASB issued Accounting Standards Update (“ASU”) 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). Under
ASU 2015-11, subsequent measurement of inventory is based on the lower of cost or net realizable value. Net realizable value is estimated selling price in the
ordinary course of business, less the estimated cost of completion and disposal. This update does not apply to inventory that is measured using last-in, first-
out or the retail inventory method. The new guidance is effective for fiscal years beginning after December 15, 2016. The Company adopted ASU 2015-11
during the first quarter of 2017, 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 No. 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  No.  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 No. 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 continues to assess the potential impact that the adoption of
ASU  2014-09,  ASU  2016-08,  ASU  2016-10  and  ASU  2016-12  will  have  on  its  consolidated  financial  statements.  Based  on  its  assessment  to  date,  the
Company  does  expect  that  the  adoption  of  this  new  accounting  standard  will  impact  the  timing  and  amount  of  assets,  liabilities,  revenue  and/or  expenses
recorded and the financial statement disclosures related to the Company’s revenue from contracts with its customers. For example, the treatment of extended
payment  terms,  contingent  revenue  elements,  commissions  and  costs  to  obtain  customer  contracts  may  change  under  the  new  accounting  standard.  The
Company is continuing to assess the impact of this new accounting standard and the expected adoption method. This assessment is subject to change, and the
Company may identify other impacts on its 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. The new guidance is effective for public companies for annual reporting periods beginning after December 15, 2018 and for
interim periods within those fiscal years. The new 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. The Company is currently assessing the potential impact that the adoption of ASU 2016-02 will have on
its consolidated financial statements.

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. The Company is currently assessing the potential impact that
the adoption of ASU 2016-13 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.

In  August  2017, 

issued  ASU  2017-12,  Derivatives  and  Hedging—Targeted  Improvements 

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

6. Fair Value Measurements

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
derive an estimate of their fair value. Changes in the fair value of SARs are recorded in operating expenses in the consolidated statements of operations and
comprehensive income.

The following tables present information about the fair value of the Company’s financial assets and liabilities as of December 31, 2017 and 2016 and

During the years ended December 31, 2017, 2016 and 2015 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:

7. Derivative Instruments

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,
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.  As  of  December  31,  2016,  the  Company  had  foreign  currency  forward  contracts  outstanding  with  notional  amounts  totaling  11,171  euros  which
matured in the first and second quarter of 2017.

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,  2016,  the  Company  recorded  an  asset  of  $60  and  as  of
December  31,  2017  and  2016,  the  Company  recorded  a  liability  of  $150  and  $56,  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.

On  December  22,  2017,  the  TCJA  was  enacted  which,  among  other  things,  lowered  the  U.S.  corporate  income  tax  rate  to  21%  from  35%  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 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.  Given  the  significant  complexity  of  the  TCJA,  anticipated  guidance  from  the  U.S.
Treasury Department about implementing the TCJA and the potential for additional guidance from the SEC or the FASB related to the TCJA or additional
information  becoming  available,  the  Company’s  provisional  charge  may  be  adjusted  during  2018  and  is  expected  to  be  finalized  no  later  than  the  fourth
quarter of 2018. Other provisions of the TCJA that impact future tax years are still being assessed.

As of December 31, 2017, the Company had state research and development tax credits of $3,340 that will begin to expire in 2030 through 2032.
Management  believes  that  it  is  more  likely  than  not  that  the  research  and  development  tax  benefit  will  be  realized  and  thus  has  not  provided  a  valuation
allowance relating to these tax credit carryforwards.

Prior  to  2017,  the  Company’s  intent  was  to  indefinitely  reinvest  the  total  amount  of  the  unremitted  earnings  of  each  of  its  foreign  subsidiaries  to
support  business  growth  in  international  regions.  As  such,  the  Company  had  not  provided  for  U.S.  taxes  on  the  unremitted  earnings  of  its  international
subsidiaries, which totaled approximately $27,850 as of December 31, 2016. Under the TCJA, the Company is required to provide U.S. taxes on cumulative
unremitted earnings from its foreign subsidiaries. The Company has estimated a U.S. tax liability on these earnings and the associated withholding taxes of

$10,031 as of December 31, 2017. The Company is still evaluating whether to change its indefinite reinvestment assertion in light of the 2017 Tax Act and
consider that conclusion to be incomplete under guidance issued by the SEC. If the Company subsequently changes our assertion during the measurement
period, such changes will be accounted for through an adjustment to the provisional income tax charge during 2018 which is expected to be finalized no later
than the fourth quarter of 2018.

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 $14, $14 and $20 for the years ended December 31, 2017, 2016 and 2015, respectively. The liability recorded for potential
penalties and interest was $158 and $145 as of December 31, 2017 and 2016, respectively. The Company had a total recorded liability of $1,142 and $463
related to uncertain tax positions, inclusive of penalties and interest, as of December 31, 2017 and 2016, respectively, which is included in accrued income
taxes, net of current portion in the consolidated balance sheets.

The aggregate changes in the balance of gross uncertain tax positions, which excludes interest and penalties, for the years ended December 31, 2017,

2016 and 2015 were as follows:

Balance at January 1, 2015

The  Company  and  its  subsidiaries  file  income  tax  returns  in  the  U.S.  federal  jurisdiction  as  well  as  various  states  and  foreign  jurisdictions.  As  of
December  31,  2017,  the  tax  years  2014  through  2017  remained  open  to  examination  in  the  U.S.  federal  jurisdiction  and  the  tax  years  2013  through  2017
remained open to examination in the Massachusetts state and China federal jurisdictions. 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.

Upon the settlement of certain stock-based awards, such as exercise, vesting, forfeiture or cancellation, the actual tax deduction is compared with the
cumulative stock-based compensation expense and any excess tax deduction related to such awards is considered a windfall tax benefit. Windfall tax benefits
are  tracked  within  a  windfall  tax  benefit  pool  to  offset  any  future  tax  deduction  shortfalls.  Prior  to  the  Company’s  adoption  of  FASB  ASU  2016-09,
Improvements to Employee Share-Based Payment Accounting, as of January 1, 2016, windfall tax benefits were recorded as increases to additional paid-in
capital in the period in which the tax deduction reduced income taxes.

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, 2017 and 2016, $297,000 and $300,000 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, the Company had used $1,000 under the
revolving  credit  facility  for  a  stand-by  letter  of  credit  that  serves  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. 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, 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. As of December 31, 2016, the interest rate on the Term Loans was 5.00% per annum, which was based on a one-month Eurodollar rate
at the applicable floor of 1.00% 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 year ended December
31, 2017. No principal payments were made during the year ended December 31, 2016.  Interest expense, including the amortization of debt issuance costs,
totaled $16,800 and $538 for the years ended December 31, 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,  2017  and  2016,  interest
expense related to the fee for the unused amount of the revolving credit facility totaled $61 and $2, 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,  commencing  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, 2017 and 2016, 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.

The Company made principal payments under the Mortgage Loan of $292, $282 and $115 during the years ended December 31, 2017, 2016 and 2015,
respectively. Interest expense, including the amortization of debt issuance costs, totaled $272, $283 and $145 for the years ended December 31, 2017, 2016
and 2015, 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, 2017 and 2016.

Prior to the closing of the IPO, changes in the liquidation preference of the preferred stock resulted from the accrual of cumulative dividends. During
the  year  ended  December  31,  2017,  the  Company  accrued  an  additional  $5,674  of  liquidation  preference  on  the  preferred  stock.    Upon  conversion  of  the
preferred stock on December 19, 2017, the Company reclassified $97,439 from temporary equity to additional paid-in capital and $40 from temporary equity
to common stock.

Preferred Stock

Upon  the  closing  of  the  IPO  on  December  19,  2017,  the  Company  filed  a  restated  certificate  of  incorporation,  which  authorized  the  issuance  of
preferred stock with rights and preferences, including voting rights, designated from time to time by the board of directors. As of December 31, 2017, there
were 5,000 shares of preferred stock authorized with a par value of $0.001 per share, and no shares of preferred stock issued or outstanding.

Special Dividends to Holders of Common and Preferred Stock

November 2017 Special Dividend

On November 30, 2017, the board of directors declared a special dividend to the holders of common stock and preferred stock of record on that date,
contingent upon the closing of the Company’s IPO. The cash dividend declared to stockholders was $0.5802 per share of common stock, $5.8020 per share of
Series B convertible preferred stock (the “Series B Preferred Stock”) and $5.8020 per share of Series C convertible preferred stock (the “Series C Preferred
Stock”). Related  to  this  special  dividend  declared  in  November  2017,  the  Company  paid  $42,137  of  dividends  to  the  common  and  preferred  stockholders

In  connection  with  this  special  dividend  declared  in  November  2017,  the  board  of  directors  also  approved,  contingent  upon  the  payment  of  the
November 2017 special dividend, cash payments to be made to holders of the Company’s stock options, SARs and RSUs as an equitable adjustment to the
holders of such instruments in accordance with the provisions of the Company’s equity incentive plans. The equitable adjustment payments to the holders of
the stock options, SARs and RSUs are equal to $0.5802 per share multiplied by the net number of shares subject to outstanding equity awards after applying
the  treasury  stock  method.  The  cash  payments  to  such  holders  will  be  made  as  their  equity  awards  vest  through  fiscal  year  2021.  During  the  year  ended
December 31, 2017, the Company paid $5,193 to the holders of such vested equity awards. As of December 31, 2017, equitable adjustment payments to be
made as equity awards vest through fiscal year 2021, net of estimated forfeitures, totaled $1,735 and were included in accrued expenses and other current
liabilities in the accompanying consolidated balance sheets.

The  cash  dividends  declared  to  the  holders  of  common  stock,  Series  B  Preferred  Stock  and  Series  C  Preferred  Stock  totaled  $19,572,  $1,039  and
$22,391, respectively, and the equitable adjustment to the holders of stock options, SARs and RSUs, net of estimated forfeitures, totaled $6,928. The $49,930
aggregate amount of such dividends and equitable adjustments was recorded as a charge to additional paid-in capital during the year ended December 31,
2017.

May 2017 Special Dividend

11. Common Stock

Upon the closing of the IPO on December 19, 2017, the Company filed a restated certificate of incorporation, which authorized the Company to issue
500,000  shares  of  $0.001  par  value  common  stock.  Each  share  of  common  stock  entitles  the  holder  to  one  vote  on  all  matters  submitted  to  a  vote  of  the
Company’s  stockholders.  Common  stockholders  are  entitled  to  receive  dividends,  as  may  be  declared  by  the  board  of  directors,  if  any,  subject  to  the
preferential  dividend  rights  of  the  preferred  stock.  Through  December  31,  2017,  except  for  the  special  cash  dividends  declared  on  November  30,  2014,
June 17, 2016, December 21, 2016, May 10, 2017 and November 30, 2017 (see Note 10), no dividends have been declared by the board of directors.

As of December 31, 2017, the Company had reserved 25,838 shares of common stock for the exercise of outstanding stock options, the vesting of

outstanding RSUs, and the number of shares remaining available for grant under the Company’s 2017 Stock Incentive Plan (see Note 12).

Stock Split

On  December  1,  2017,  the  Company  effected  a  five-for-one  stock  split  of  its  issued  and  outstanding  shares  of  common  stock  and  a  proportional
adjustment to the existing conversion ratio of each series of the Company’s Convertible Preferred Stock (see Note 10). Accordingly, all share and per share
amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable,
to reflect this stock split and adjustment of the preferred stock conversion ratios.

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.

98

 
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 10,023
shares as of December 31, 2017, of which 9,363 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.

The assumptions used in the Black-Scholes option-pricing model were as follows:

Risk-free interest rate
Expected term (in years)
Expected volatility
Expected dividend yield

The weighted-average grant-date fair value of options granted during the years ended December 31, 2017, 2016 and 2015 was $4.74, $3.71 and $2.75
per share, respectively. Cash proceeds received upon the exercise of options were $274, $594 and $226 during the years ended December 31, 2017, 2016 and
2015, respectively. The intrinsic value of stock options exercised during the years ended December 31, 2017, 2016 and 2015 was $1,915, $5,001 and $720,
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 January 31, 2017 and May 15, 2017, the Company granted 176 and 15 RSUs, respectively, under the 2011 Plan.  On December 15, 2017, the
Company granted 35 RSUs under the 2017 Plan.  On March 26, 2016 and January 23, 2015, the Company granted 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 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, 2017 is as follows:

Stock Appreciation Rights

In  January  2017,  the  Company  granted  110  SARs  that  allow  the  holder  the  right,  upon  exercise,  to  receive  in  cash  the  amount  of  the  difference
between the fair value of the Company’s common stock at the date of exercise and the price of the underlying common stock at the date of grant of each SAR.
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,  2017,  240  SARs  were  outstanding  and  68  were

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, 2017 and 2016, 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,
2017, 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 $1,484, $1,313 and $977 in the years ended December 31, 2017, 2016 and 2015, respectively.

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,  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

This Annual Report on Form 10-K does not include a report of management's assessment regarding internal control over financial reporting or an
attestation  report  of  the  Company's  registered  public  accounting  firm  due  to  a  transition  period  established  by  rules  of  the  Securities  and  Exchange
Commission for newly public 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.

Jerry Guo, the founder of our company, has served as our president and chief executive officer and as the chairman of our board of directors since our
founding  in  2003.  Prior  to  founding  our  company,  Mr.  Guo  served  as  the  Vice  President  of  Broadband  at  River  Delta  Networks,  which  was  acquired  by
Motorola  in  2001.  Prior  to  that,  Mr.  Guo  was  a  research  scientist  at  Bell  Laboratories’  research  division.  Mr.  Guo  holds  a  Ph.D.  degree  in  electrical
engineering from the University of Wisconsin-Madison and an M.S. degree in optical instruments from the Department of Precision Instruments at Tsinghua
University. We believe that Mr. Guo is qualified to serve on our board of directors due to his leadership experience in the broadband and network industries,
his extensive knowledge of our company and his service as our president and chief executive officer.

Gary Hall has served as our chief financial officer since June 2011. Prior to joining Casa, from April 2007 to March 2010, Mr. Hall was the chief
financial  officer  of  eCopy,  a  provider  of  document  management  solutions.  From  August  2004  to  June  2006,  he  served  as  the  chief  financial  officer  of
MatrixOne, a product life-cycle management company, where he had previously served as controller from April 1999 to August 2004. Previously, Mr. Hall
served in various accounting and auditing roles at Deloitte & Touche, a multinational professional services firm. Mr. Hall holds a M.S. degree in finance from
Bentley College and a B.A. degree in accounting from Southern New Hampshire University.

Chen served as a software manager at Motorola, a multinational telecommunications company from October 2001 to November 2003. Mr. Chen holds a Ph.D.
degree  in  physics  from  the  University  of  Pennsylvania.  We  believe  that  Mr.  Chen’s  deep  experience  in  the  telecommunications  industry,  his  extensive
knowledge of our company and his position as our chief technology officer enable Mr. Chen to make a valuable contribution to our board of directors.

Lucy Xie has served as our senior vice president of operations since 2011 and as a member of our board of directors since 2003. From 2003 to 2011,
Ms.  Xie  served  as  our  chief  financial  officer  and  vice  president  of  operations.  Prior  to  joining  Casa,  Ms.  Xie  held  various  accounting,  finance  and
management  positions  at  Raytheon,  a  U.S.  defense  contractor  and  industrial  corporation,  and  Lucent  Technologies,  a  telecommunications  equipment
company. Ms. Xie has also served as the vice chairman and a board member of the Asia-America Chamber of Commerce. Ms. Xie holds an M.B.A. degree in
accounting from Fairleigh Dickinson University. We believe that Ms. Xie is qualified to serve on our board of directors due to her experience as an executive
in the telecommunications industry, her extensive knowledge of our company and her service as our senior vice president of operations.

Abraham Pucheril has served as our senior vice president of product strategy and management since January 2018 and as our senior vice president of

Bruce R. Evans has been a director of our company since 2010. Since 1986, Mr. Evans has served in various positions with Summit Partners, a growth
equity  and  venture  capital  investment  firm,  including  most  recently  as  Chairman  of  the  Summit  Partners’  Board  of  Managers  and  Senior  Advisor  to  the
firm. He is also currently a director of Analog Devices, a public company which designs and manufactures high-performance semiconductor products, as well

Board of Trust. Mr. Evans holds a B.E. degree in mechanical engineering and economics from Vanderbilt University and an M.B.A. degree from Harvard
Business  School.  We  believe  that  Mr.  Evans  is  qualified  to  serve  as  a  director  of  our  company  due  to  his  wide-ranging  experience  in  growth  equity  and
venture capital investing in the technology sector and his experience on other private and public company boards.

Bill Styslinger has been a director of our company since 2012. Mr. Styslinger served as chairman, president and chief executive officer of SeaChange
International, a provider of multiscreen video software and services, from its inception in July 1993 until his retirement in December 2011. Mr. Styslinger was
also previously a member of the board of directors of Omtool, a provider of enterprise client/server facsimile software solutions. Mr. Styslinger holds a B.S.
degree in Engineering Science from the State University of New York at Buffalo. We believe that Mr. Styslinger is qualified to serve on our board of directors
due to his leadership expertise, including service as chief executive officer of a public company with international operations, as well as his knowledge of the
telecommunications industry.

Joe Tibbetts  has  been  a  director  of  our  company  since  November  2017.  Since  March  2017,  Mr.  Tibbetts  has  served  as  the  interim  chief  financial
officer  of  Acquia  Corporation,  a  provider  of  cloud-based,  digital  experience  management  solutions.  Prior  to  that,  Mr.  Tibbetts  served  as  the  senior  vice
president and chief financial officer of the Publicis.Sapient unit of Publicis Group SA, from February 2015, when Publicis acquired Sapient Corporation, to
September 2015. Prior to that, Mr. Tibbetts served as senior vice president and global chief financial officer for Sapient Corporation from October 2006 to
February  2015.  Mr.  Tibbetts  was  formerly  a  partner  with  Price  Waterhouse  LLP.  Mr.  Tibbetts  currently  serves  on  the  board  of  directors  of  Vivint,  Inc.,  a
provider  of  home  automation  equipment  and  services,  Vivint  Solar,  Inc.,  a  provider  of  home  solar  energy  solutions,  and  one  other  private  company.  Mr.
Tibbetts holds a B.S. in business administration from the University of New Hampshire. We believe that Mr. Tibbetts is qualified to serve on our board of
directors due to his experience as an executive officer or director of other technology companies and his financial and accounting expertise.

Jerry Guo and Lucy Xie are married to one another. There are no other family relationships among any of our directors or executive officers.

reports of holdings and transactions in our common stock and other securities of ours with the Securities Exchange Commission. Based solely on our review
of copies of such forms that we have received, or written representations from reporting persons, we believe that during the fiscal year ended December 31,

Act.

Retirement Benefits

We  maintain  a  retirement  plan  for  the  benefit  of  our  employees,  including  our  named  executive  officers. The  plan  is  intended  to  qualify  as  a  tax-
qualified 401(k) plan so that contributions to the 401(k) plan, and income earned on such contributions, are not taxable to participants until withdrawn or
distributed from the 401(k) plan (except in the case of contributions under the 401(k) plan designated as Roth contributions). Under the 401(k) plan, each
employee  is  fully  vested  in  his  or  her  deferred  salary  contributions.  Employee  contributions  are  held  and  invested  by  the  plan’s  trustee  as  directed  by
participants. We match 50% of employee contributions to our 401(k) plan up to a maximum amount of 6% of eligible wages.

Employee Benefits and Perquisites

Our named executive officers are eligible to participate in our health and welfare plans to the same extent as all full-time employees.

During the year ended December 31, 2017, we paid to Bill Styslinger of an annual cash retainer of $200,000, payable quarterly in arrears, for his
services as a director and an annual cash retainer of $5,000, payable annually in arrears, for his services as a member of the compensation committee of our
board  of  directors.  This  arrangement  terminated  upon  the  closing  of  our  initial  public  offering  on  December  19,  2017.  In  addition,  in  connection  with
Mr. Tibbetts’ appointment to our board of directors, we granted to Mr. Tibbetts, upon the commencement of trading of our common stock on the Nasdaq
Global Select Market on December 15, 2017, restricted stock units for 23,076 and 11,538 shares, respectively, with the restricted stock unit for 23,076 shares
vesting  on  a  quarterly  basis  over  a  period  of  three  years  after  the  date  of  his  appointment  to  our  board  of  directors  and  the  restricted  stock  unit  for
11,538 shares vesting on the first anniversary of the date of his appointment to our board of directors, in each case subject to Mr. Tibbetts’ continued service
as  a  director,  with  full  acceleration  of  vesting  upon  a  change  in  control  of  our  company.  Such  grants  were  intended  to  be  consistent  with  our  new  non-
employee director compensation program described below. Prior to our initial public offering, none of our other directors received compensation for service
on our board of directors or committees of our board of directors during the year ended December 31, 2017.

We also have a policy of reimbursing our directors for their reasonable out-of-pocket expenses incurred in attending board of directors and committee

meetings.

In November 2017, we approved a non-employee director compensation program that became effective upon the closing of our initial public offering
on December 19, 2017. Under this program, non-employee directors receive the cash compensation set forth below, and an additional payment of $150,000
annually, commencing with election or appointment to our board of directors, to be paid, at the discretion of our board of directors, in the form of cash or
cash-settled  or  stock-settled  restricted  stock  units  for  the  number  of  shares  of  our  common  stock  equal  to  $150,000  divided  by  the  closing  price  of  our
common stock on the Nasdaq Global Select Market on the date of grant. Any such cash-settled or stock-settled restricted stock units will vest one year after
the date of grant. In addition, new non-employee directors also receive an additional initial equity grant of cash-settled or stock-settled restricted stock units
for the number of shares of our common stock equal to $300,000 divided by the closing price of our common stock on the Nasdaq Global Select Market on
the date of such director’s initial election to our board of directors. Such cash-settled or stock-settled restricted stock units will vest on a quarterly basis, over
a period of three years after the date of grant, subject to the non-employee director’s continued service as a director, with full acceleration of vesting upon a
change in control of our company.

Under our non-employee director compensation program, each non-employee director is eligible to receive compensation for his or her service on our

board of directors or committees thereof consisting of annual cash retainers paid quarterly in arrears, as follows:

Stock Option and Other Compensation Plans

Prior to our initial public offering, we granted awards under our 2003 Stock Incentive Plan, as amended to date, and our 2011 Stock Incentive Plan, as
amended to date. In connection with our initial public offering, we started granting awards under our 2017 Stock Incentive Plan and ceased granting awards
under all prior plans.

2017 Stock Incentive Plan

The 2017 Stock Incentive Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock
awards, RSUs and other stock-based awards. The number of shares of our common stock that are reserved for issuance under the 2017 Stock Incentive Plan is
equal to the sum of: (1) 7,160,685 plus; (2) the number of shares (up to 18,746,045 shares) equal to the sum of the number of shares of our common stock
then  available  for  issuance  under  the  2003  Stock  Incentive  Plan  and  the  2011  Stock  Incentive  Plan  as  of  immediately  prior  to  the  effectiveness  of  the
registration  statement  for  our  initial  public  offering  and  the  number  of  shares  of  our  common  stock  subject  to  outstanding  awards  under  the  2003  Stock
Incentive Plan and the 2011 Stock Incentive Plan that expire, terminate or are otherwise surrendered, cancelled, forfeited or repurchased by us at their original
issuance price pursuant to a contractual repurchase right; plus (3) an annual increase, to be added on the first day of each fiscal year, beginning with the fiscal
year ending December 31, 2019 and continuing until, and including, the fiscal year ending December 31, 2027, equal to the lowest of 20,000,000 shares of
our common stock, 4% of the number of shares of our common stock outstanding on the first day of such fiscal year and an amount determined by our board
of directors.

Our  employees,  officers,  directors,  consultants  and  advisors  are  eligible  to  receive  awards  under  the  2017  Stock  Incentive  Plan.  Incentive  stock
options,  however,  may  only  be  granted  to  our  employees.Pursuant  to  the  terms  of  the  2017  Stock  Incentive  Plan,  our  board  of  directors  (or  a  committee
delegated by our board of directors) administers the plan and, subject to any limitations in the plan, will select the recipients of awards and determine:

•

•

•

•

•

the number of shares of our common stock covered by options and the dates upon which the options become exercisable;

the type of options to be granted;

the duration of options, which may not be in excess of ten years;

the exercise price of options, which must be at least equal to the fair market value of our common stock on the date of grant; and

the number of shares of our common stock subject to and the terms of any stock appreciation rights, restricted stock awards, RSUs or other
stock-based awards and the terms and conditions of such awards, including conditions for repurchase, issue price and repurchase price (though
the measurement price of stock appreciation rights must be at least equal to the fair market value of our common stock on the date of grant and
the duration of such awards may not be in excess of ten years).

If our board of directors delegates authority to an executive officer to grant awards under the 2017 Stock Incentive Plan, the executive officer will
have the power to make awards to all of our employees, except executive officers. Our board of directors will fix the terms of the awards to be granted by
such executive officer, including the exercise price of such awards (which may include a formula by which the exercise price will be determined), and the
maximum number of shares subject to awards that such executive officer may make.

Effect of Certain Changes in Capitalization. Upon the occurrence of any stock split, reverse stock split, stock dividend, recapitalization, combination
of shares, reclassification of shares, spin-off or other similar change in capitalization or event, or any dividend or distribution to holders of our common stock
other than an ordinary cash dividend, our board of directors shall equitably adjust:

•

•

the number and class of securities available under the 2017 Stock Incentive Plan;

the share counting rules under the 2017 Stock Incentive Plan;

114

 
 
 
 
 
 
 
 
 
•

•

•

•

the number and class of securities and exercise price per share of each outstanding option;

the share and per-share provisions and the measurement price of each outstanding stock appreciation right;

the number of shares subject to, and the repurchase price per share subject to, each outstanding restricted stock award; and

the share and per-share related provisions and the purchase price, if any, of each other stock-based award.

Effect of Certain Corporate Transactions. Upon a merger or other reorganization event (as defined in our 2017 Stock Incentive Plan), our board of
directors may, on such terms as our board of directors determines (except to the extent specifically provided otherwise in an applicable award agreement or
other agreement between the participant and us), take any one or more of the following actions pursuant to the 2017 Stock Incentive Plan as to some or all
outstanding awards, other than restricted stock awards:

•

•

•

•

•

provide  that  all  outstanding  awards  shall  be  assumed,  or  substantially  equivalent  awards  shall  be  substituted,  by  the  acquiring  or  successor
corporation (or an affiliate thereof);

upon  written  notice  to  a  participant,  provide  that  all  of  the  participant’s  unvested  and/or  vested  but  unexercised  awards  will  terminate
immediately prior to the consummation of such reorganization event unless exercised by the participant (to the extent then exercisable);

provide that outstanding awards shall become exercisable, realizable or deliverable, or restrictions applicable to an award shall lapse, in whole
or in part, prior to or upon such reorganization event;

in the event of a reorganization event pursuant to which holders of shares of our common stock will receive a cash payment for each share
surrendered  in  the  reorganization  event,  make  or  provide  for  a  cash  payment  to  the  participants  with  respect  to  each  award  held  by  a
participant  equal  to  (1)  the  number  of  shares  of  our  common  stock  subject  to  the  vested  portion  of  the  award  (after  giving  effect  to  any
acceleration of vesting that occurs upon or immediately prior to such reorganization event) multiplied by (2) the excess, if any, of the cash
payment  for  each  share  surrendered  in  the  reorganization  event  over  the  exercise,  measurement  or  purchase  price  of  such  award  and  any
applicable tax withholdings, in exchange for the termination of such award; and/or

provide that, in connection with a liquidation or dissolution, awards shall convert into the right to receive liquidation proceeds (if applicable,
net of the exercise, measurement or purchase price thereof and any applicable tax withholdings).

Our board of directors does not need to take the same action with respect to all awards, all awards held by a participant or all awards of the same type.

In  the  case  of  certain  RSUs,  no  assumption  or  substitution  is  permitted,  and  the  RSUs  will  instead  be  settled  in  accordance  with  the  terms  of  the

applicable RSU agreement.

Upon  the  occurrence  of  a  reorganization  event  other  than  a  liquidation  or  dissolution,  the  repurchase  and  other  rights  with  respect  to  outstanding
restricted stock awards will continue for the benefit of the successor company and will, unless the board of directors may otherwise determine, apply to the
cash,  securities  or  other  property  into  which  shares  of  our  common  stock  are  converted  or  exchanged  pursuant  to  the  reorganization  event.  Upon  the
occurrence  of  a  reorganization  event  involving  a  liquidation  or  dissolution,  all  restrictions  and  conditions  on  each  outstanding  restricted  stock  award  will
automatically be deemed terminated or satisfied, unless otherwise provided in the agreement evidencing the restricted stock award or any other agreement
between the participant and us.

At any time, our board of directors may, in its sole discretion, provide that any award under the 2017 Stock Incentive Plan will become immediately

exercisable in full or in part, free of some or all restrictions or conditions, or otherwise realizable in whole or in part as the case may be.

No award may be granted under the 2017 Stock Incentive Plan after December 13, 2027. Our board of directors may amend, suspend or terminate the

2017 Stock Incentive Plan at any time, except that stockholder approval may be required to comply with applicable law or stock market requirements.

As of February 28, 2018, options to purchase 664,000 shares of common stock were outstanding under the 2017 Stock Incentive Plan, at a weighted-
average exercise price of $13.38 per share, and no options to purchase shares of our common stock had been exercised. In addition, as of such date, 32,691
RSUs were outstanding under the 2017 Stock Incentive Plan.

2011 Stock Incentive Plan

The 2011 Stock Incentive Plan provided for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock
units and shares, restricted or otherwise, of our common stock. Our employees, officers, directors, consultants and advisors were eligible to receive awards
under our 2011 Stock Incentive Plan; however incentive stock options could only be granted to our employees. The type of award granted under our 2011
Stock Incentive Plan and the terms of such award are set forth in the applicable award agreement.

Pursuant to the terms of the 2011 Stock Incentive Plan, our board of directors (or a committee assigned by our board of directors) administers the 2011
Stock Incentive Plan. The board of directors has complete discretion to take any actions it deems necessary or advisable for the administration of the 2011
Stock Incentive Plan. All decisions, interpretations and other actions of our board of directors are final and binding on all participants and all persons deriving
their rights from a participant. In addition, subject to any limitations in the 2011 Stock Incentive Plan, our board of directors selected the recipients of awards
and determined:

•

•

•

•

•

the number of shares of our common stock covered by options and the dates upon which the options become exercisable;

the type of options to be granted;

the duration of options, which could not be in excess of ten years;

the exercise price of options, which was required to be at least equal to the fair market value of our common stock on the date of grant; and

the number of shares of our common stock subject to, and the terms of any restricted stock awards or restricted stock units, and the terms and
conditions of such awards, including conditions for repurchase, issue price and repurchase price.

Effect of Certain Changes in Capitalization. Pursuant to the 2011 Stock Incentive Plan, in the event of stock split, stock dividend, a combination of
shares, reverse stock-split, a reclassification, or any other increase or decrease in the number of issued shares of our common stock effected without receipt of
consideration by us, proportionate adjustments shall automatically be made in each of:

•

•

•

the number of shares of our common stock available for issuance under the 2011 Stock Incentive Plan;

the number of shares of our common stock covered by each outstanding option or RSU granted under the 2011 Stock Incentive Plan; and

the exercise price under each outstanding option granted under the 2011 Stock Incentive Plan.

Our board of directors, in its sole discretion, may also make appropriate adjustments to one or more of the same items described above in the event of
a declaration of an extraordinary dividend payable in a form other than shares of our common stock that has a material effect on the fair market value of
shares of our common stock, a recapitalization, a spin-off or any similar occurrence.

Effect of Certain Corporate Transactions. In the event that we are a party to a merger or consolidation, all shares of our common stock acquired under
the 2011 Stock Incentive Plan and all awards outstanding under the 2011 Stock Incentive Plan on the effective date of the transaction shall be treated in the
manner described in the agreement of merger or consolidation, which agreement need not treat all awards in an identical manner but which must preserve an
award’s status as exempt from or compliant with Section 409A of the Internal Revenue Code of 1986, as amended, or the Code, and must provide for one or
more of the following:

•

•

•

continuation of the outstanding award by us if we are the surviving corporation;

assumption, or substitution of substantially equivalent awards, of the outstanding award by the surviving corporation or its parent, provided
that the assumption or substitution is accomplished in a manner that complies with the rules regarding assumptions or substitutions that apply
to incentive stock options under the Code (whether the outstanding award is an incentive stock option or a nonstatutory stock option);

acceleration of the date of exercise or vesting of an option (which may be contingent on the closing of the merger or consolidation) followed
by the termination of the option if it is not timely exercised prior to the closing of the merger or consolidation (which exercise may also be
contingent on the closing of the merger or consolidation); or

116

 
 
 
 
 
 
 
 
 
 
 
 
•

cancellation of the outstanding award in exchange for a payment (if any) equal to the fair market value of a share of common stock as of the
closing date of the merger or consolidation minus the per-share exercise price of the award (if any).

Subject to the limitations of the 2011 Stock Incentive Plan, our board of directors may modify, extend or assume outstanding options and RSUs and
may accept the cancellation of outstanding options in return for the grant of new options for the same or a different number of shares of our common stock or
a different exercise price.

As  of  February  28,  2018,  options  to  purchase  14,723,365  shares  of  common  stock  were  outstanding  under  the  2011  Stock  Incentive  Plan,  at  a
weighted-average exercise price of $4.23 per share, and options to purchase 3,207,780 shares of our common stock had been exercised. In addition, as of such
date, 371,855 RSUs were outstanding under the 2011 Stock Incentive Plan.

No further awards will be made under our 2011 Stock Incentive Plan; however, awards outstanding under our 2011 Stock Incentive Plan will continue

to be governed by their existing terms.

2003 Stock Incentive Plan

The 2003 Stock Incentive Plan provided for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock
units and shares, restricted or otherwise, of our common stock. Our employees, officers, directors, consultants and advisors were eligible to receive awards
under our 2003 Stock Incentive Plan; however incentive stock options could only be granted to our employees.

The type of award granted under our 2003 Stock Incentive Plan and the terms of such award are set forth in the applicable award agreement.

Pursuant to the terms of the 2003 Stock Incentive Plan, our board of directors (or a committee assigned by our board of directors) administers the
2003 Stock Incentive Plan. The board of directors has complete discretion to take any actions it deems necessary or advisable for the administration of the
2003 Stock Incentive Plan. All decisions, interpretations and other actions of our board of directors are final and binding on all participants and all persons
deriving their rights from a participant. In addition, subject to any limitations in the 2003 Stock Incentive Plan, our board of directors selected the recipients
of awards and determined:

•

•

•

•

•

the number of shares of our common stock covered by options and the dates upon which the options become exercisable;

the duration of options, which could not be in excess of ten years;

the exercise price of options, which was required to be at least equal to the fair market value of our common stock on the date of grant; and

the number of shares of our common stock subject to, and the terms of any restricted stock awards or restricted stock units, and the terms and
conditions of such awards, including conditions for repurchase, issue price and repurchase price.

Effect of Certain Changes in Capitalization. Pursuant to the 2003 Stock Incentive Plan, in the event of stock split, stock dividend, a combination of
shares, reverse stock-split, a reclassification, or any other increase or decrease in the number of issued shares of our common stock effected without receipt of

117

 
 
 
 
 
 
 
 
 
 
Our board of directors, in its sole discretion, may also make appropriate adjustments to one or more of the same items described above in the event of
a declaration of an extraordinary dividend payable in a form other than shares of our common stock that has a material effect on the fair market value of
shares of our common stock, a recapitalization, a spin-off or any similar occurrence.

Effect of Certain Corporate Transactions. In the event that we are a party to a merger or consolidation, all shares of our common stock acquired under

cancellation of the outstanding award in exchange for a payment (if any) equal the fair market value of a share of common stock as of the
closing date of the merger or consolidation minus the per-share exercise price of the award (if any).

may accept the cancellation of outstanding options in return for the grant of new options for the same or a different number of shares of our common stock or

As of February 28, 2018, options to purchase 145,830 shares of common stock were outstanding under the 2003 Stock Incentive Plan, at a weighted-
average exercise price of $0.25 per share, and options to purchase 2,564,170 shares of our common stock had been exercised. In addition, as of such date no
RSUs were outstanding under the 2003 Stock Incentive Plan.

No further awards will be made under our 2003 Stock Incentive Plan; however, awards outstanding under our 2003 Stock Incentive Plan continue to

be governed by their existing terms. 

Limitation of Liability and Indemnification

Our restated certificate of incorporation limits the personal liability of directors for breach of fiduciary duty to the maximum extent permitted by the
Delaware General Corporation Law and provides that no director will have personal liability to us or to our stockholders for monetary damages for breach of
fiduciary duty or other duty as a director. However, these provisions do not eliminate or limit the liability of any of our directors:

•

•

•

•

for any breach of the director’s duty of loyalty to us or our stockholders;

for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

for voting or assenting to unlawful payments of dividends, stock repurchases or other distributions; or

for any transaction from which the director derived an improper personal benefit.

Any amendment to, or repeal of, these provisions will not eliminate or reduce the effect of these provisions in respect of any act, omission or claim
that  occurred  or  arose  prior  to  such  amendment  or  repeal.  If  the  Delaware  General  Corporation  Law  is  amended  to  provide  for  further  limitations  on  the
personal  liability  of  directors  of  corporations,  then  the  personal  liability  of  our  directors  will  be  further  limited  to  the  greatest  extent  permitted  by  the
Delaware General Corporation Law.

In  addition,  our  restated  certificate  of  incorporation  provides  that  we  must  indemnify  our  directors  and  officers  and  we  must  advance  expenses,

including attorneys’ fees, to our directors and officers in connection with legal proceedings, subject to very limited exceptions.

118

 
 
 
 
 
 
 
 
 
We  maintain  a  general  liability  insurance  policy  that  covers  certain  liabilities  of  our  directors  and  officers  arising  out  of  claims  based  on  acts  or
omissions in their capacities as directors or officers. In addition, we have entered into indemnification agreements with each of our directors and executive
officers. These indemnification agreements may require us, among other things, to indemnify each such director and executive officer for some expenses,
including attorneys’ fees, judgments, fines and settlement amounts incurred by him or her in any action or proceeding arising out of his or her service as one
of our directors or executive officers.

Certain of our non-employee directors may, through their relationships with their employers, be insured and/or indemnified against certain liabilities
incurred in their capacity as members of our board of directors. We have agreed that we will be the indemnitor of “first resort,” however, with respect to any
claims against these directors for indemnification claims that are indemnifiable by both us and their employers. Accordingly, to the extent that indemnification
is permissible under applicable law, we will have full liability for such claims (including for the advancement of any expenses) and we have waived all related
rights of contribution, subrogation or other recovery that we might otherwise have against these directors’ employers.

Rule 10b5-1 Sales Plans

Our directors and executive officers may adopt written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell
shares of our common stock on a periodic basis. Under a Rule 10b5-1 plan, a broker executes trades pursuant to parameters established by the director or
officer when entering into the plan, without further direction from them. The director or officer may amend or terminate the plan in some circumstances. Our
directors and executive officers may also buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material, nonpublic
information.

Compensation Committee Interlocks and Insider Participation

None of our executive officers serves as a member of the board of directors or compensation committee, or other committee serving an equivalent
function, of any entity that has one or more executive officers who serve as members of our board of directors or our compensation committee. None of the
members of our compensation committee is an officer or employee of our company, nor have they ever been an officer or employee of our company.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

The following table sets forth information with respect to the beneficial ownership of our common stock, as of February 28, 2018, by:

•

•

•

•

each person, or group of affiliated persons, known by us to beneficially own more than 5% of our common stock;

each of our directors;

each of our named executive officers; and

all of our executive officers and directors as a group.

The  column  entitled  “Percentage  of  Shares  Beneficially  Owned”  is  based  on  a  total  of  81,580,281  shares  of  our  common  stock  outstanding  as  of

February 28, 2018.

The number of shares beneficially owned by each stockholder is determined under rules of the SEC and includes voting or investment power with
respect  to  securities.  Under  these  rules,  beneficial  ownership  includes  any  shares  as  to  which  the  individual  or  entity  has  sole  or  shared  voting  power  or
investment power. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of
common stock subject to options or other rights held by such person that are currently exercisable or will become exercisable within 60 days after February
28, 2018, are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other
person. Unless otherwise indicated, the address of all listed stockholders is c/o Casa Systems, Inc., 100 Old River Road, Andover, Massachusetts 01810. Each
of  the  stockholders  listed  has  sole  voting  and  investment  power  with  respect  to  the  shares  beneficially  owned  by  the  stockholder  unless  noted  otherwise,
subject to community property laws where applicable. Beneficial ownership representing less than 1% is denoted with an asterisk (*).

with  special  dividends  declared  by  our  board  of  directors  in  December  2016,  May  2017  and  November 2017,  our  board  of  directors  also  approved  cash

Indemnification Agreements

Our restated certificate of incorporation provides that we will indemnify our officers and directors to the fullest extent permitted by Delaware law. In
addition, we have entered into indemnification agreements with each of our other directors and executive officers. See “Item 11. Executive Compensation—
Limitation of Liability and Indemnification.”

Arrangements with Executive Officers

For  a  description  of  the  compensation  arrangements  that  we  have  with  our  named  executive  officers  and  directors,  see  “Item  11.  Executive

Compensation”.

Policies and Procedures for Related Person Transactions

We have adopted written policies and procedures for the review of any transaction, arrangement or relationship in which our company is a participant,
the  amount  involved  exceeds  $120,000,  and  one  of  our  executive  officers,  directors,  director  nominees  or  5%  stockholders  (or  their  immediate  family
members), each of whom we refer to as a “related person,” has a direct or indirect material interest.

If  a  related  person  proposes  to  enter  into  such  a  transaction,  arrangement  or  relationship,  which  we  refer  to  as  a  “related  person  transaction,”  the
related  person  must  report  the  proposed  related  person  transaction. The  policy  will  call  for  the  proposed  related  person  transaction  to  be  reviewed  and,  if
deemed appropriate, approved by the audit committee of our board of directors. Whenever practicable, the reporting, review and approval will occur prior to
entry into the transaction. If advance review and approval is not practicable, the committee will review, and, in its discretion, may ratify the related person
transaction.  The  policy  will  also  permit  the  chairman  of  the  audit  committee  to  review  and,  if  deemed  appropriate,  approve  proposed  related  person
transactions that arise between audit committee meetings, subject to ratification by the audit committee at its next meeting. Any related person transactions
that are ongoing in nature will be reviewed annually.

A  related  person  transaction  reviewed  under  the  policy  will  be  considered  approved  or  ratified  if  it  is  authorized  by  the  audit  committee  after  full

disclosure of the related person’s interest in the transaction. As appropriate for the circumstances, the audit committee will review and consider:

•

•

•

•

•

•

•

the related person’s interest in the related person transaction;

the approximate dollar value of the amount involved in the related person transaction;

the approximate dollar value of the amount of the related person’s interest in the transaction without regard to the amount of any profit or loss;

whether the transaction was undertaken in the ordinary course of our business;

whether the terms of the transaction are no less favorable to us than terms that could have been reached with an unrelated third party;

the purpose of, and the potential benefits to us of, the transaction; and

any other information regarding the related person transaction or the related person in the context of the proposed transaction that would be
material to investors in light of the circumstances of the particular transaction.

122

 
 
 
 
 
 
 
 
The  audit  committee  may  approve  or  ratify  the  transaction  only  if  it  determines  that,  under  all  of  the  circumstances,  the  transaction  is  in  or  is  not

inconsistent with our company’s best interests. The audit committee may impose any conditions on the related person transaction that it deems appropriate.

In addition to the transactions that are excluded by the instructions to the SEC’s related person transaction disclosure rule, the policy will provide that
the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for
purposes of this policy:

•

•

•

•

•

•

•

•

•

•

•

•

interests arising only from the related person’s position as a director of another corporation or organization that is a party to the transaction;

interests arising only from the direct or indirect ownership by the related person and all other related persons in the aggregate of less than a
10% equity interest (other than a general partnership interest) in another entity which is a party to the transaction;

interests arising from both the position and ownership level described above;

interests arising solely from the related person’s position as an executive officer of another entity (whether or not the person is also a director
of such entity), that is a participant in the transaction, where (a) the related person and all other related persons own in the aggregate less than
a 10% equity interest in such entity, (b) the related person and his or her immediate family members are not involved in the negotiation of the
terms of the transaction and do not receive any special benefits as a result of the transaction and (c) the amount involved in the transaction
equals less than the greater of $200,000 or 5% of the annual gross revenues of the company receiving payment under the transaction;

interests arising solely from the ownership of a class of our equity securities if all holders of that class of equity securities receive the same
benefit on a pro rata basis;

a  transaction  that  involves  compensation  to  an  executive  officer  if  the  compensation  has  been  approved,  or  recommended  to  our  board  of
directors  for  approval,  by  the  compensation  committee  of  the  board  of  directors  or  a  group  of  independent  directors  of  ours  performing  a
similar function;

a transaction that involves compensation to a director for services as one of our directors if such compensation will be reported pursuant to
Item 402(k) of Regulation S-K;

a transaction that is specifically contemplated by provisions of our certificate of incorporation or bylaws;

interests arising solely from indebtedness of a significant stockholder or an immediate family member of a significant stockholder of ours, as
such terms are defined under the policy;

a transaction where the rates or charges involved in the transaction are determined by competitive bids;

a transaction that involves the rendering of services as a common or contract carrier or public utility at rates or charges fixed in conformity
with law or governmental authority; and

a transaction that involves services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services.

The  policy  will  provide  that  transactions  involving  compensation  of  executive  officers  shall  be  reviewed  and  approved  by  the  compensation

committee in the manner specified in its charter.

Director Independence

Rule 5605 of the Nasdaq Listing Rules requires a majority of a listed company’s board of directors to be comprised of independent directors within
one year of listing. In addition, the Nasdaq Listing Rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation
and nominations committees be independent, or, if a listed company has no nominations committee, that director nominees be selected or recommended for
the  board’s  selection  by  independent  directors  constituting  a  majority  of  the  board’s  independent  directors,  and  that  audit  committee  members  also  satisfy
independence criteria set forth in Rule 10A-3 under the Exchange Act and compensation committee members must also satisfy the independence criteria set
forth in Rule 10C-1 under the Exchange Act. Under Rule 5605(a)(2), a director will only qualify as an “independent director” if, in the opinion of our board
of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a
director. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or
her capacity as a member of the audit committee, the board of directors, or any other board committee, accept,

123

 
 
 
 
 
 
 
 
 
 
 
 
 
directly  or  indirectly,  any  consulting,  advisory  or  other  compensatory  fee  from  the  listed  company  or  any  of  its  subsidiaries  or  otherwise  be  an  affiliated
person of the listed company or any of its subsidiaries.

The phase-in periods with respect to director independence under the Nasdaq Listing Rules allow us to have only one independent member on each of
the audit committee and compensation committee upon the listing date of our common stock, a majority of independent members on each committee within
90 days of the listing date (or the effective date of the registration statement, in the case of the audit committee) and fully independent committees and a
majority of independent directors on our board of directors within one year of the listing date (or the effective date of the registration statement, in the case of
the audit committee). 

In November 2017, our board of directors undertook a review of the composition of our board of directors and its committees and the independence of
each  director.  Based  upon  information  requested  from  and  provided  by  each  director  concerning  his  or  her  background,  employment  and  affiliations,
including family relationships, our board of directors has determined that each of Messrs. Evans and Tibbetts is an “independent director” as defined under
Rule 5605(a)(2) of the Nasdaq Listing Rules. In making such determinations, our board of directors considered the relationships that each such non-employee
director has with our company and all other facts and circumstances our board of directors deemed relevant, including the beneficial ownership of our capital
stock  by  each  non-employee  director  and  any  institutional  stockholder  with  which  he  is  affiliated.  Mr.  Evans,  Mr.  Tibbetts  and  Ms.  Xie  are  the  current
members of our audit committee, and Mr. Evans and Mr. Styslinger are the current members of our compensation committee.

We expect to satisfy the member independence requirements for each of the audit and compensation committees of our board of directors prior to the
end  of  the  transition  period  provided  under  Nasdaq  Listing  Rules  and  SEC  rules  and  regulations  for  companies  that  have  recently  completed  their  initial
public offering.

We do not intend to form a nominating and corporate governance committee at this time, and the independent members of our board of directors will

be responsible for nominations.

All  Other  Fees  represent  fees  for  products  and  services  provided  by  PricewaterhouseCoopers  LLP  that  are  not  included  in  the  service  categories

Pre-Approval Policies and Procedures

The audit committee of our board of directors has adopted policies and procedures for the pre-approval of audit and non-audit services for the purpose
of maintaining the independence of our independent auditor. We may not engage our independent auditor to render any audit or non-audit service unless either
the  service  is  approved  in  advance  by  the  audit  committee,  or  the  engagement  to  render  the  service  is  entered  into  pursuant  to  the  audit  committee’s  pre-
approval  policies  and  procedures.  Notwithstanding  the  foregoing,  pre-approval  is  not  required  with  respect  to  the  provision  of  services,  other  than  audit,
review or attest services, by the independent auditor if the aggregate amount of all such services is no more than 5% of the total amount paid by us to the
independent auditor during the fiscal year in which the services are provided, such services were not recognized by us at the time of the engagement to be
non-audit services and such services are promptly brought to the attention of the audit committee and approved prior to completion of the audit by the audit
committee or its chairman.

124

 
 
 
 
 
 
 
 
 
 
 
 
 
From  time  to  time,  our  audit  committee  may  pre-approve  services  that  are  expected  to  be  provided  to  us  by  the  independent  auditor  during  the
following 12 months. At the time such pre-approval is granted, the audit committee must identify the particular pre-approved services in a sufficient level of
detail so that our management will not be called upon to make a judgment as to whether a proposed service fits within the pre-approved services and, at each
regularly  scheduled  meeting  of  the  audit  committee  following  such  approval,  management  or  the  independent  auditor  shall  report  to  the  audit  committee
regarding each service actually provided to us pursuant to such pre-approval.

The  audit  committee  has  delegated  to  its  chairman  the  authority  to  grant  pre-approvals  of  audit  or  non-audit  services  to  be  provided  by  the

independent auditor. Any approval of services by the chairman of the audit committee is reported to the committee at its next regularly scheduled meeting.

I have reviewed this Annual Report on Form 10-K of Casa Systems, Inc.;

period covered by this report;

Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the Registrant as of, and for, the periods presented in this report;

The Registrant's other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) for the Registrant and have:

(a) Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision,
to ensure that material information relating to the Registrant, including its consolidated subsidiaries, is made known to us by others within
those entities, particularly during the period in which this report is being prepared;

(b) Evaluated the effectiveness of the Registrant's disclosure controls and procedures and presented in this report our conclusions about the
effectiveness of the disclosure controls and procedures, as of the end of the period covered by this report based on such evaluation; and
(c) Disclosed in this report any change in the Registrant's internal control over financial reporting that occurred during the Registrant's most

recent fiscal quarter (the Registrant's fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely

5.

The Registrant's other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to
the Registrant's auditors and the audit committee of the Registrant's board of directors (or persons performing the equivalent functions):  

(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are
reasonably likely to adversely affect the Registrant's ability to record, process, summarize and report financial information; and

control over financial reporting.
