Item 1.

Business     

Overview

We  are  a  provider  of  secure,  integrated,  intelligent  communication  and  workflow  solutions,  focused  on  empowering  mobile  workers  in  healthcare,  hospitality,
energy, and other mission-critical mobile work environments in the United States and internationally. Today, the significant majority of our business is generated
from sales of our solutions in the healthcare market to help our customers improve quality of care, patient experience, staff resiliency and operational efficiency.
Care teams at nearly 1,600 healthcare facilities worldwide have selected our solutions to call and text securely, reduce alarm fatigue, and to enhance workflow and
help improve patient experience. Our solutions can also be found in hotels, nuclear facilities, retail stores and other environments where mobile workers need to
communicate and access resources instantly.

Our communication and collaboration solution, which includes an intelligent enterprise software platform; lightweight, wearable, voice-controlled communication
devices; as well as smartphone applications, enables users to connect instantly with other staff simply by saying the name, function or group name of the desired
recipient. It also delivers HIPAA-compliant secure text messages, alerts and alarms directly to smartphones and other mobile communication devices both inside
and outside the hospital, replacing legacy pagers and in-building wireless phones.

At the core of this solution is a patent-protected, enterprise-class server software platform. Our software platform is built on a scalable architecture and recognizes
more than 100 spoken commands. Users can instantly communicate with others using the Vocera Smartbadge or Vocera Badge, or through client applications for
iOS and Android devices. Our platform lets users communicate and collaborate with each other using voice or HIPAA-compliant secure texting, and unlike other
solutions, allows users to reach people by their role, room assignment or department, without needing to know a person’s name or phone number. The system can
also  broadcast  emergency  messages  to  a  single  department  or  to  an  entire  organization.  Our  solution  can  be  integrated  with  other  clinical  systems,  including
Electronic Health Records (EHR), nurse call, patient monitoring and even some medical devices, to provide critical data, alerts, alarms and clinical context that
enables  better  workflow.  Our  enterprise-class  software  platform  also  features  an  advanced  clinical  rules  engine  that  unifies  data  from  multiple  sources
simultaneously,  enables  prioritization  of  notifications,  adds  patient  context,  and  sends  messages  to  the  right  care  team  members  on  their  mobile  devices.  Our
platform allows clinicians to be away from the bedside while staying informed about their patients. Our portfolio of over 140 unique integrations enhances clinical
workflow by enabling the interoperability of our solution with a significant number of clinical and operational systems used in hospitals today.

Beyond  healthcare,  our  solutions  are  used  to  quickly  and  contextually  connect  staff  in  other  mission-critical  mobile-worker  environments.  In  the  hospitality
industry, it is used to enhance guest experience, as well as staff productivity and responsiveness. In the nuclear power industry, our solutions are used to instantly
connect people and resources. In education, schools use our solutions to increase security and staff communication and libraries use it to enable their staff to be
more mobile and attentive to patrons.

Table of Contents

Over our 19-year history, we have significantly enhanced and added features and functionality to these solutions through ongoing development based on frequent
interactions with our customers. In January 2019, we introduced the Vocera Smartbadge which combines smartphone usability with the same wearable, hands-free
features as the Vocera Badge. The new Vocera Smartbadge has a 2.4" touchscreen, which enables clinicians view and send secure text messages as well as receive
alerts and notifications with patient context.

Vocera  Care  Experience  is  a  hosted  software  suite  that  coordinates  and  streamlines  provider-to-patient  and  provider-to-provider  communication  in  order  to
improve  quality  of  care,  patient  and  staff  experience,  reduce  care  provider's  risk  and  improve  reimbursements.    The  solution  provides  personalized  patient
instructions and education; provides alerts and notifications to physicians and caregivers of patients’ changing care plans or status; and tracks patient experience
before, during and after hospitalization.

Our Experience Innovation Network, a thought leadership collaborative, is a membership-based program designed to spread the adoption of leading strategies to
improve patient experience and staff resiliency.

As  of  December  31,  2018,  our  solutions  were  selected  by  nearly  1,600  healthcare  facilities,  including  large  hospital  systems,  small  and  medium-sized  local
hospitals, clinics, surgery centers and aged-care facilities. We sell our solutions to our healthcare customers primarily through our direct sales force in the United
States, with resellers for certain U.S. Government business, and through both direct sales and select distribution channels in international markets.

We were incorporated in Delaware on February 16, 2000. Our corporate headquarters are located at 525 Race Street, San Jose, California 95126, and our main
telephone  number  is  (408)  882‑5100.  We  maintain  a  website  at  www.vocera.com.  The  contents  of  our  website  are  not  incorporated  into,  or  otherwise  to  be
regarded as part of, this Annual Report on Form 10-K.

Industry overview

Vocera provides communication and workflow solutions for mobile workers in healthcare, hospitality, energy, education and other industries. Healthcare is our
largest vertical market.

Hospital  communication  is  still  predominantly  conducted  through  multiple  disparate,  non-integrated  systems,  including  pagers,  overhead  paging,  portable  in-
building wireless phones and individuals’ personal mobile phones. These non-integrated communication methods are inefficient and often unreliable; not providing
“closed loop” communication, workflow standardization, or the scale required by health systems. Further, they often contribute to noisy environments for patients
and negatively impact healing, safety, quality of care and operational efficiency.

Broadly, we believe the healthcare industry is placing greater emphasis on the need for better communication and workflow to meet increasing requirements for
care quality, patient safety, efficiency and patient satisfaction. Healthcare providers also require greater coordination of care among clinicians as the industry shifts
towards population health and paying for value instead of the traditional fee-for-service reimbursement model. This shift to value-based purchasing incorporates
financial  incentives  for  hospitals  to  improve  the  quality  of  care  and  patient  satisfaction.  A  number  of  non-government  organizations,  such  as  The  Joint
Commission,  are  also  requiring  improvements  in  patient  safety  and  quality  of  care.  These  forces  are  driving  hospitals  to  invest  in  technology  and  process
improvements  to  manage  their  operations  more  efficiently,  improve  quality  of  care,  and  increase  patient  satisfaction  and  staff  resiliency.  Our  solutions  help
hospitals  increase  productivity  and  reduce  costs  by  enhancing  workflow  and  improving  patient  and  staff  satisfaction  through  secure,  integrated  and  intelligent
communication.

Our strategy

Our goal is to extend  our leadership  position  as a provider  of communication  and workflow solutions  in the  healthcare  market  and add new customers  in non-
healthcare markets.

Key elements of our strategy include:

•

•

Expand our business to new U.S. healthcare customers.     We believe our solutions can provide significant value to health systems, hospitals and smaller
healthcare facilities. We plan to continue to add new customers among hospitals of all sizes, and expand to outpatient clinics and skilled nursing facilities.

Further expand our footprint within our existing installed customer base.     Many of our customers initially deploy our solutions in a few departments of a
hospital and gradually expand to additional departments as they come to fully appreciate its value. We have a significant opportunity to up-sell and cross-sell
to our existing  customers,  including  into new hospitals  that  are part  of an existing  healthcare  system  customer.  Key sales  strategies  include expanding  our
footprint at existing

customer  facilities  and  capturing  additional  revenue  by  cross  selling  additional  solutions.  We  plan  to  continue  expanding  within  our  existing  customers  in
order to grow our revenue and maintain and improve customer experience.

Extend our technology advantage and create new product solutions.     We intend to continue our investment in research and development to enhance the
functionality of our solutions and further differentiate  them from other competing solutions. As we did with the introduction of the Smartbadge in January
2019, we plan to continue to invest in product upgrades, product line extensions and new solutions to enhance our portfolio, including further development of
applications for iOS and Android devices.

Increase our health system selling efforts. Our increasingly comprehensive product suite is enabling us to sell to large health systems.  These sales efforts
typically involve conversations with more senior decision makers and result in larger deal sizes with complex and elongated sales cycles.  We have organized
a national accounts sales team to pursue more of these opportunities in the future.

Invest in partnerships. In order to gain access to clinical data and patient context needed to create a highly efficient communication and workflow system for
the  entire  care  team,  we  plan  to  continue  to  broaden  our  ecosystem  of  technology  partners,  including  vendors  that  provide  nurse  call  systems,  patient
monitoring systems, analytics and EHRs. We added new partnerships in 2018 and will continue to explore new relationships that broaden our overall market
presence and accelerate the sales of our offerings.

Pursue acquisitions of complementary businesses, technologies and assets.     Over the last seven years we have completed a number of acquisitions to help
us achieve our strategic vision by enhancing our products and enabling us to enter new markets. Our acquisitions have expanded our solutions, demonstrating
that  we  can  successfully  source,  acquire  and  integrate  complementary  businesses,  technologies  and  assets.  We  intend  to  continue  to  pursue  acquisition
opportunities that we believe can accelerate the growth of our business.

Grow our international healthcare presence.     Today, in addition to our core U.S. market, we sell into other English-speaking markets, including Canada,
the United Kingdom, Australia, New Zealand, and Middle Eastern countries including the United Arab Emirates, Saudi Arabia, Oman and Qatar. We believe
that the rapid pace of investment in new healthcare facilities in these developing international markets provides a significant opportunity for growth. As of
December 31, 2018, our solutions were selected by approximately 280 healthcare facilities outside the United States. We plan to utilize both our direct sales
force and leverage channel partners to expand our presence into other markets over time.

Expand our solutions in non-healthcare markets.      While  our  primary  focus  is on  the  healthcare  market,  our solutions  also  provide  great  value  in  non-
healthcare markets. Our solutions have been selected by facilities in markets beyond healthcare including hospitality, energy and other mission critical mobile
worker environments. Currently, this is not a material portion of our revenue, but longer term, we believe these markets could represent potential opportunities
for growth.

Our products, technology and services

Our solutions include the Vocera Communication and Workflow System, Vocera Care Experience and our Experience Innovation Network, a thought leadership
collaborative. To complement our solutions, we provide services, support and education to help our customers optimize the benefits of our solutions.

Vocera Communication and Workflow System

The Vocera Communication and Workflow System is comprised of a unique software platform that connects communication devices, including our hands-free,
wearable, voice-controlled communication Smartbadge and Badge, and third-party mobile devices that use our software applications to become our enterprise-class
software platform. The system transforms the way mobile workers communicate by enabling them to instantly connect via voice or secure text messaging. With a
portfolio  of  over 140 third-party  party  clinical  integrations,  our system  also  enables  the intelligent  delivery  of alerts  and alarms  to  a variety  of  mobile  devices,
providing real time situation awareness to care providers. Our hands-free voice capability allows mobile workers to connect with the right person simply by saying
or selecting the name, function or group name of the person they want to reach, often while remaining at the point-of-care. Our system responds to over 100 spoken
commands.

Some examples of common commands are shown below.

Vocera Software Platform.     At the heart of our Vocera Communication and Workflow System is a patent-protected, enterprise-class software platform. The
intelligence  of  our  client-server  system  is  contained  primarily  within  our  server-software.  This  platform  contains  an  optimized  speech  recognition  engine,
intelligent  call  routing  and  management  functionality,  reporting  and  analytics  tools,  clinical  directories  and  user  profiles.  In  addition,  our  platform  has  the
ability  to  integrate  with  a  significant  number  of  third-party  clinical  systems,  including  telephony,  nurse  call,  patient  monitoring  and  EHR  systems.  Our
software platform features an advanced clinical rules engine that unifies data from multiple sources simultaneously, enables prioritization of notifications, adds
patient context, and sends messages to the right care team members on their mobile devices, helping to improve patient safety and satisfaction and increase
operational efficiency. By providing real-time situational awareness about the patients and care teams, we enable healthcare workers to be more effective and
suffer less from alarm and alert fatigue. Recognizing the rapidly expanding footprint of care, our scalable software platform can support multiple geographic
sites and multiple facilities within a healthcare system to help clinicians stay connected to the current status of their patients.

Vocera Smartbadge . Our Smartbadge, launched in January 2019, is the only wearable communication device purpose-built for patient care. Our Smartbadge
is  powered  by  the  Vocera  Software  Platform  and  operates  over  customers'  industry-standard  Wi-Fi  networks.  The  Smartbadge  has  a  2.4”  touchscreen  and
keyboard that enables the user to receive prioritized alert and alarm notifications with additional patient context. Additionally users can make and answer calls
hands-free or by holding it up to the ear for privacy, and send and receive secured text messages with no character limit. The Smartbadge also has a dedicated
panic button and enhanced "do not disturb" functionality.

Vocera Badge .     Our Badge is a smaller and lighter weight hands-free wearable device that allows the users instant two-way voice conversations without the
need  to  remember  a  phone  number  or  use  a  handset.  Similar  to  the  Smartbadge,  it  is  powered  by  the  Vocera  Software  Platform  and  operates  over  the
customers' industry-standard Wi-Fi networks. It has a small display that provides a concise amount of information and allows the user to receive prioritized
alarm  and  alert  notifications  with  limited  context.  The  Badge  has  received  the  FIPS  140-2  certification  from  the  National  Institute  of  Standards  and
Technology.  We  have  also  received  an  Authority  to  Operate  (ATO)  certification  from  the  U.S.  Department  of  Defense.  Both  of  these  certifications  are
requirements to sell our solutions to U.S. government and military hospital and medical facilities.

Vocera  Smartphone Applications.  Vocera's  suite  of  smartphone  applications  enable  a  seamless  multi-mode  communications  and  collaboration  experience;
combining the unique calling, texting, alerting and content distribution capabilities of Vocera into a secure, easy-to-use smartphone application. Available and
certified for use on commercially-available iOS and Android devices, our smartphone applications support both personal (BYOD) and shared device usage
models. A specific version of our smartphone software includes our instant voice communication solution and our secure enterprise messaging and alerting
solution  that  enable  the  robust,  reliable  and  HIPAA-compliant  delivery  of  critical  pages,  text,  messages,  alarms  and  alerts.  Users  can  receive  and  send
messages from smartphones, through a web-based console, or through integrated third-party clinical systems.

Choice  of  Mobile  Devices.  We  resell  the  Zebra  Technologies  TC51  Android  mobile  computer.  These  devices  are  offered  as  a  bundled  solution  with  our
smartphone  applications  to  provide  a  complete,  turnkey  solution  for  our  customers’  clinical  communication  needs.  We  also  deliver  our  solution  on  iOS
devices. This gives our customers a choice of different devices to access the power of the Vocera software platform.

Marketing

Our  marketing  efforts  focus  on  building  awareness  and  generating  demand.  We  believe  that  continuing  to  increase  our  brand  recognition  is  important  for  the
growth of our business as well as generating demand for our solutions. As of December 31, 2018, we had 33 employees in marketing, product management and
business development.

Our customer-centric marketing strategy is important to generating new sales leads as word of mouth promotion and testimonials are some of our most valuable
marketing  tools.  A  number  of  our  customers  have  agreed  to  participate  in  video  testimonials,  white  papers  and  case  studies  that  validate  the  efficacy  and  the
financial benefits of our solutions. We have been featured in numerous articles and on network television demonstrating increased patient satisfaction, streamlined
hospital operations and enhanced employee satisfaction and safety. Additionally, we sponsor numerous customer-led webinars to demonstrate customer success
and to let prospective customers hear from their peer group about the positive impact that our solutions have made on their hospitals. Many of our sales leads come
from referrals of existing customers or users who have moved from a hospital already using Vocera to a new facility or health system. We also invest in digital
outreach to better influence buyers early on in their decision-making.

We have an integrated product management organization that manages the full lifecycle of our products and services; from strategy through execution to end-of-
life. Our product roadmaps are driven by current and prospective customers and continually validated using primary and secondary research. We collect customer
feedback through surveys and focus groups, customer visits, a customer advisory board, user forums and participation in industry standards organizations. Integral
to this team are product managers and user experience designers skilled in clinical and operating workflows, and business development resources that create and
manage the ecosystems of clinical and technology system partners.

Customers

Our solutions have been selected by more than 1,850 facilities worldwide. Of these, nearly 1,600 are hospitals and other healthcare facilities, and approximately
280 are outside of the United States. Our healthcare customers include national and international health and hospital systems, large and medium-sized independent
and academic hospitals, small hospitals and healthcare facilities, and U.S. governmental hospitals and care facilities. With our diverse customer base, we have very
low customer revenue concentration.

During 2018 , 2017 and 2016, non-U.S. markets represented approximately 10.2% , 10.2% , and 10.4% of our revenue, respectively. We are developing plans to
offer our solutions in a wider range of international markets.

Competition

We do not believe any single competitor offers a similar intelligent communication system to the healthcare market that allows instant, hands-free communication
through voice-activated, role-based and activity-based calling, secure texting, and clinical integrations and workflows, and that features an advanced clinical rules
engine  that  unifies  data  from  multiple  sources  simultaneously  on a combination  of dedicated,  proprietary  devices,  as well as  third-party  smartphones  and other
devices.

At this time, the primary alternative to our system consists of a combination of traditional communication methods utilizing wired phones, wireless in-building
phones, smartphones, pagers and overhead paging systems.

The  most  significant  alternative  with  which  we  compete  for  sales  in  the  hospital  are  in-building  wireless  telephones  and  smartphone  applications.  While  we
compete with the providers of these wireless phones in making sales to hospitals, they do not at this time purport to contain the system intelligence, integrated
workflow  and  convenience  of  our  communication  and  workflow  solutions.  The  market  for  in-building  wireless  phones  is  dominated  by  large  communications
companies such as Cisco Systems, Ascom and Spectralink.

Additionally, we compete against Epic and Cerner, both of which have their own smartphone application for secure texting. We differentiate against these
Electronic Health Record (EHR) vendors as we enable hands-free communication via our Smartbadge and Badge and clinical workflow with our large portfolio of
over 140 system integrations.

We believe that the use of mobile smartphone apps for healthcare will continue to expand in our target market and may represent a source of competition but this
trend also represents an opportunity to expand our communication solutions with our smartphone applications, which enable all members of the patient's care team
to connect to our software platform and participate as users on our Communication system.

We believe that the primary competitive factors at work in our market include:

•
•
•
•

comprehensiveness of the solution and the features provided and the ability to purchase the complete solution from a single vendor
product performance and reliability
the initial cost and ongoing cost of ownership
customer service and support capabilities

Table of Contents

We may face increased competition in the future, including from large, multinational companies or private equity backed organizations with significant resources.
Potential competitors may have existing relationships with purchasers of other products and services within the hospital, which may enhance their ability to gain a
foothold in our market. In addition, the continuing expansion of our communication and workflow collaboration capabilities, may introduce us to a broader set of
competitors. These competitors may include companies that provide clinical workflow solutions, enterprise software, cloud-based solutions and electronic health
records.

Research and development

Our continued investment in research and development is critical to our business. We have assembled teams of engineers with expertise in various fields, including
software,  firmware,  database  design,  applications,  speech  recognition,  wireless  communication  and  hardware  design.  We  employ  research  and  development
personnel  in  San  Jose,  California;  Fort  Wayne,  Indiana;  Knoxville,  Tennessee;  Toronto,  Canada  and  Bangalore,  India.  There  were  179 full-time  research  and
development employees as of December 31, 2018 . We also utilized small teams of contractors in India and Ukraine to assist with quality assurance testing and
automation, and targeted development efforts.

Intellectual property

Our success depends, in part, upon our ability to protect our core technology and intellectual property. To accomplish this, we rely on a combination of intellectual
property rights, including patents, trade secrets, copyrights and trademarks, as well as customary contractual protections.

We held 28 U.S. patents as of December 31, 2018, including patents on many capabilities of our software platform and wearable devices.  The expiration dates of
these patents range from 2021 through 2032. One or more utility patents have also been issued in Australia, Canada, India, Japan and the European Patent Office
(with  validation  in  Germany,  United  Kingdom  and  Netherlands).  A  European  Community  design  patent  has  been  issued  that  protects  the  design  in  multiple
European jurisdictions.

In addition to the foregoing protections, we generally control access to and use of our proprietary software and other confidential information through the use of
internal and external controls, including non-disclosure agreements and other statutory and contractual protections applicable to employees, contractors, customers
and partners. These protections include U.S. and international copyright laws.

Our solutions include software developed and owned by us as well as software components we have licensed. These non-exclusive licenses are terminable by the
licensor for cause. Certain of these licenses are for a contractually specified term and cannot be renewed without the assent of the licensor. In the event one or more
of these licenses is terminated or is not renewed, we could be required to redesign substantial portions of our software in order to incorporate software components
from alternative sources. An unplanned redesign of our software could materially and adversely affect our business.

Manufacturing operations and suppliers

We  outsource  the  manufacturing  of  our  wearable  device  products  to  original  design  manufacturers  and  contract  manufacturers,  including  Sercomm  and  SMTC
Corporation (SMTC). Our Vocera Smartbadge is built in Taiwan and our Vocera Badge is made in Mexico using custom tools and test equipment owned by us.
Most of our accessories, including batteries, chargers and attachments, are built by original design manufacturers (ODMs) in Asia.

These manufacturers are responsible for procuring all the components included in our products, as specified and approved by us. Some of these components are
sole-sourced off-the-shelf and some are custom components built exclusively for our products. In the event we are unable to procure certain components, we could
be required to redesign some of our products in order to incorporate technology from alternative sources. An unplanned redesign of our products could materially
and adversely affect our business.

We  require  our  suppliers  to  perform  both  incoming  and  outgoing  product  inspections.  In  addition,  we  perform  in-house  quality  control  and  ongoing  reliability
testing.

We  also  resell  the  Zebra  Technologies  TC51  Android  mobile  computer.  These  devices  are  offered  as  a  bundled  solution  with  our  smartphone  applications  to
provide a complete, turnkey solution for our customers’ clinical communication needs.

Employees

As of December 31, 2018 , we had 630 employees, consisting of 20 in manufacturing and quality operations, 179 in research and development, 185 in sales and
marketing, 181 in  services  and  support  and  65 in  general  and  administrative.  None  of  our  employees  are  covered  by  a  collective  bargaining  agreement  or  are
represented by a labor union. We consider current employee relations to be good.

Backlog

Our backlog of undelivered orders was $61.8 million and $64.4 million at December 31, 2018 and 2017 , respectively. Of the current backlog, all but $28.9 million
is expected to be delivered in 2019.

Government regulations and standards

Substantially all of our revenue is derived from the healthcare industry. The healthcare industry is highly regulated and is subject to changing political, legislative,
regulatory and other influences. These factors affect the purchasing practices and operations of healthcare organizations, as well as the behavior and attitudes of
our  users.  Representatives  of  the  U.S.  federal  legislature  and  agencies  have  announced  plans  to  reform  or  revise  aspects  of  the  U.S.  healthcare  system  and  we
expect these efforts to continue over the next several years. We also expect federal and state legislatures and agencies to continue to consider new programs to
reform or revise aspects of the U.S. healthcare system. These programs may contain proposals to increase governmental involvement in healthcare or otherwise
change the environment in which healthcare industry participants operate.

HIPAA privacy and security standards     

In connection with our healthcare communications business, we access personal health information on behalf of our customers. Accordingly, in the United States,
we are subject to the Health Insurance Portability and Accountability Act of 1996 (HIPAA), and its implementing regulations, which established uniform standards
for certain “covered entities” (healthcare providers engaged in electronic transactions, health plans and healthcare clearinghouses) governing the conduct of certain
electronic healthcare transactions and protecting the security and privacy of protected health information. The American Recovery and Reinvestment Act of 2009
included sweeping expansion of HIPAA’s privacy and security standards as reflected in the Health Information Technology for Economic and Clinical Health Act,
(HITECH).  Among  other  things,  the  new  law  makes  certain  HIPAA  privacy  and  security  standards  directly  applicable  to  “business  associates”  -  independent
contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity.
HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state
attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and
costs associated  with pursuing  federal  civil  actions.  Most  of our customers  are  covered  entities  under HIPAA and,  to the extent  that  we access  personal  health
information on their behalf, we are their “business associates” and are subject to HIPAA and associated contractual obligations, as well as comparable state privacy
and security laws.

In  addition,  we  are  subject  to  privacy  and  security  regulations  in  other  jurisdictions.  For  example,  the  European  Union  (EU)  adopted  the  Data  Protection
Directive  (DPD)  (officially  Directive  95/46/EC),  imposing  strict  regulations  and  establishing  a  series  of  requirements  regarding  the  storage  of  personally
identifiable  information  on computers or recorded  on other electronic  media. This has been implemented  by all EU member states through national  laws. DPD
provides for specific regulations requiring all non-EU countries doing business with EU member states to provide adequate data privacy protection when receiving
personal data from any of the EU member states. In May 2016, the EU formally adopted the General Data Protection Regulation, which applied to all EU member
states beginning May 2018 and replaces the current DPD. The regulation introduced new data protection requirements in the EU and substantial fines for breaches
of  the  data  protection  rules.  It  increased  our  responsibility  and  liability  in  relation  to  personal  data  that  we process  and  we put  in  place  additional  mechanisms
ensuring compliance with the new EU data protection rules.  Additionally, Canada’s Personal Information and Protection of Electronic Documents Act provides
Canadian  residents  with  privacy  protections  in  regard  to  transactions  with  businesses  and  organizations  in  the  private  sector  and  sets  out  ground  rules  for  how
private sector organizations may collect, use and disclose personal information in the course of commercial activities.

These statutes, regulations and contractual obligations impose numerous requirements regarding the use and disclosure of personal health information with which
we must comply, and subject us to material liability and other adverse impacts to our business in the event we fail to do so. These include, without limitation, civil
fines, criminal sanctions in certain circumstances, contractual liability to our customers, and damage to our brand and reputation. We endeavor to mitigate these
risks  through  measures  we  believe  to  be  appropriate  for  the  specific  circumstances,  including  storing  personal  data  under  our  control  on  password-protected
systems in secure facilities, counseling our customers as to best practices in using our solutions, and encrypting such information.

Medical device regulation

The U.S. Food and Drug Administration (FDA) regulates certain products, including software-based products, as “medical devices” based, in part, on the intended
use of the product and the risk the device poses to the patient should the device fail to perform properly. We have concluded that our communication products are
general-purpose communication solutions and are not subject to FDA regulation. However, either the FDA could disagree with our conclusion or changes in our
product or the FDA’s evolving regulations could lead to the imposition of medical device regulation on more of our products. In this event, we would be subject
to  additional  regulatory  requirements,  including  the  expense  of  compliance  with  Medical  Device  Reporting  and  Quality  System  regulation  and  the  potential  of
liability for failure to comply, and we could be required to obtain 510(k) clearance

10

Table of Contents

or premarket approval of those products from the FDA prior to commercial distribution. Some of the products acquired as a result of the Extension Healthcare and
mVisum acquisitions are regulated by the FDA as Class II medical devices under applicable law and FDA regulations. This includes potentially being subject to
the 2.3% excise tax that was initially legislated under the Affordable Care Act, but which has been delayed through 2019 by a moratorium on the tax included in
recent  Congressional  budget  legislation  passed  in  January  of  2018.  Class  II  devices  are  devices  classified  by  the  FDA  as  posing  a  moderate  to  high  risk  and
therefore subject to both “general controls” and “special controls,” as such terms are defined in the Food, Drug and Cosmetics Act. Further, our other products
could become subject to the 2.3% excise tax when it becomes effective, if the FDA were to determine in the future that they constitute medical devices.

Electrical standards and FCC regulations

Our  products  emit  radio  frequency  energy  in  the  2.4 and  5.0  GHz spectrum  bands  for  which  licensing  by U.S.  and  other  regulatory  authorities  is  not  required,
provided that the products conform to certain requirements, e.g., maximum power output and tolerance of interference from other devices sharing that spectrum
band. We subject our products to testing by independent testing laboratories for compliance with the relevant standards issued by various U.S. and international
bodies, including the EU (with respect to the “CE” mark), the International Electrotechnical Commission, the Australian Communications and Media Authority,
Underwriters Laboratories and CSA International.

Item 1A. Risk Factors

Investing in our common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the
other information set forth in this Annual Report on Form 10-K. Our business, financial condition, results of operations or future prospects could be materially
and adversely harmed if any of the following risks, or other risks or uncertainties that are not yet identified or that we currently believe are immaterial, actually
occur. The trading price of our common stock could decline due to any of these risks or uncertainties, and, as a result, you may lose all or part of your investment.

Risks related to our business and industry

We have incurred significant losses in the past, and will likely experience losses in the future.

We have incurred significant losses in the past and reported a net loss of $9.7 million for the year ended December 31, 2018. As of December 31, 2018 , we had an
accumulated  deficit  of  $132.3  million  .  If  we  cannot  make  consistent  progress  toward  future  profitability,  our  business  and  our  stock  price  may  be  adversely
affected.

Our  ability  to  be  profitable  in  the  future  depends  upon  continued  demand  for  our  solutions  from  existing  and  new  customers.  Further  market  adoption  of  our
solutions, including increased penetration within our existing customers, depends upon our ability to improve quality of care and patient and staff satisfaction and
increase  hospital efficiency  and productivity,  and bring  value  to customers  outside  of healthcare.  In addition,  our profitability  will be affected  by, among other
things, our ability to execute on our business strategy, the timing and size of orders, the pricing and costs of our solutions, macroeconomic conditions affecting the
health care industry and the extent to which we invest in sales and marketing, research and development and general and administrative resources.

We depend on sales in the healthcare market for substantially all of our revenue, and a decrease in sales in the healthcare market would harm our business.

To date, substantially all of our revenue has been derived from sales to the healthcare market and, in particular, hospitals. Sales to the healthcare market accounted
for 97%, 97% and 97% of our revenue for the years ended December 31, 2018, 2017 and 2016, respectively. We anticipate that sales to the healthcare market will
represent a significant portion of our revenue for the foreseeable future.

Most  of  our  solutions  require  a  substantial  upfront  investment  by  new  customers.  The  cost  of  the  initial  deployment  depends  on  the  number  of  users  and
departments involved, the size and age of the hospital and the condition of the existing wireless

12

 
Table of Contents

infrastructure, if any, within the hospital. Even if hospital personnel determine that our solutions provide compelling benefits over their existing communications
methods, their hospitals may not have, or may not be willing to spend, the resources necessary to install and maintain wireless infrastructure to initially deploy and
support our solutions or expand our solutions to other departments  or users. Hospitals face significant  budget constraints  from unpredictable  patient  population
trends and commercial reimbursements, and increasing demands from, and competition for, patients. In addition, both governmental and commercial hospitals are
experiencing lower Medicare reimbursement rates and higher compliance demands, and as part of the tax reform law that came into effect in December 2017, the
tax penalty for violating the individual health insurance mandate under the Patient Protection and Affordable Care Act of 2010 (ACA) was set to zero effective in
2019, essentially repealing it. The President of the United States and members of Congress have also attempted to repeal or amend the ACA, as well as continue to
undertake other healthcare reforms. As a consequence of these regulatory and other factors, we may experience slowdowns and deferral of orders for our solutions,
or customers may choose other less expensive solutions, both of which could negatively impact our sales. We might not be able to sustain or increase our revenue
from sales of our solutions, or achieve the growth rates that we envision, if hospitals continue to face significant budgetary constraints and reduce their spending on
communications systems.

While we are seeking to increase sales of our solutions to non-healthcare customers, we do not anticipate non-healthcare markets to represent a significant portion
of our revenue for the foreseeable future.

If we fail to successfully develop and introduce new solutions and features to existing solutions, our revenue, operating results and reputation could suffer.

Our  success  depends,  in  part,  upon  our  ability  to  develop  and  introduce  new  solutions  and  features  to  existing  solutions  that  meet  existing  and  new  customer
requirements. We may not be able to develop and introduce new solutions or features on a timely basis or in response to customers’ changing requirements, or that
sufficiently  differentiate  us  from  competing  solutions  such  that  customers  can  justify  deploying  our  solutions.  We  expect  to  incur  costs  associated  with  the
development  and  introduction  of  new  solutions  before  the  anticipated  benefits  or  the  returns  are  realized,  if  at  all.  We  may  experience  technical  problems  and
additional costs as we introduce new features to our software platform, deploy future models of our wireless badges (like the new Smartbadge), which can require
customers to perform software upgrades to their systems, and integrate new solutions with existing customer clinical systems and workflows. In addition, we may
face technical difficulties  as we expand into non-English speaking countries and incorporate non-English speech recognition capabilities  into our solutions. We
also may incur substantial costs or delays in the manufacture of any additional new products or models as we seek to optimize production methods and processes at
our  contract  manufacturer.  In  addition,  we  expect  that  we  will  at  least  initially  achieve  lower  gross  margins  on  new  models,  while  endeavoring  to  reduce
manufacturing costs over time. If any of these problems were to arise, our revenue, operating results and reputation could suffer.

If we fail to offer high-quality services and support for any of our solutions, our operating results and our ability to sell those solutions in the future will be
harmed.

Our  ability  to  sell  our  solutions  is  dependent  upon  our  professional  services  and  technical  support  teams  providing  high-quality  services  and  support.  Our
professional  services  team  assists  our  customers  with  their  wireless  infrastructure  assessment,  clinical  workflow  design,  communication  solution  configuration,
clinical  integration,  training  and  project  management  during  the  pre-deployment  and  deployment  stages.  Once  our  solutions  are  deployed  within  a  customer’s
facility, the customer typically depends on our technical support team to help resolve technical issues, assist in optimizing the use of our solutions and facilitate
adoption of new functionality. If we do not effectively assist our customers in deploying our solutions, succeed in helping our customers quickly resolve technical
and other post-deployment issues, or provide effective ongoing support services, our ability to expand the use of our solutions with existing customers and to sell
our  solutions  to  new  customers  will  be  harmed.  If  deployment  of  our  solutions  is  deemed  unsatisfactory,  we  may  incur  significant  costs  to  attain  and  sustain
customer satisfaction or, in extreme cases, our customers may choose not to deploy our solutions. As we rapidly hire new services and support personnel, we may
inadvertently hire underperforming people who will have to be replaced, or fail to effectively train such employees, leading in some instances to slower growth,
additional costs and poor customer relations. In addition, the failure of channel partners to provide high-quality services and support in markets outside the United
States could also harm sales of our solutions.

As we continue to pursue opportunities for larger deals that have greater technical complexity, including deals that require more complex integrations with our
customer’s workflows, we may experience a longer time period for our solutions to deploy and as a result, our revenue recognition for these deals may be delayed.
Additionally, as we enter agreements with new and existing customers for larger and more complex deals across multiple sites, we have been, and may continue to
be, required to agree to customer acceptance clauses. Delays may occur in obtaining customer acceptance regardless of the quality of our products and services,
and may cause us to defer revenue recognition where such acceptance provisions are substantive in nature, or they may require us to incur additional professional
services or other costs in an effort to obtain such customer acceptance.

Our sales cycle can be lengthy and unpredictable, which may cause our revenue and operating results to fluctuate significantly.

Our sales cycles can be lengthy and unpredictable. Our sales efforts involve educating our customers about the use and benefits of our solutions, including the
technical  capabilities  of  our  solutions  and  the  potential  cost  savings  and  productivity  gains  achievable  by  deploying  them.  Customers  typically  undertake  a
significant evaluation process, which frequently involves not only our solutions but also their existing communications methods and those of our competitors, and
can result in a lengthy sales cycle, that sometimes exceeds twelve months. With our introduction of the Smartbadge, it may take our customers additional time to
evaluate this new device and to compare it with our existing Badge and other solutions. This may also result in delays and reductions in orders for our existing
Badge.  We  spend  substantial  time,  effort  and  money  in  our  sales  efforts  without  any  assurance  that  our  efforts  will  produce  sales.  Similarly,  our  increasing
dependence on larger, hospital-wide deployments may increase fluctuations in our revenue and operating results because the failure to complete a significant sale,
or the loss of a large customer, will have a greater impact on those results . In addition, purchases of our solutions are frequently subject to budget constraints,
multiple approvals, and unplanned administrative, processing and other delays. We have experienced and may continue to experience elongated sales cycles due to
ongoing  uncertainty  surrounding  past  and  future  healthcare  reform  legislation,  the  impact  of  shifting  federal  government  budgets,  changes  to  Medicare  and
Medicaid reimbursement and potential future statutes and rulemaking.

Our business has gone through cycles of expansion, relative stability and contraction, and if we are not able to manage such cycles effectively, our operating
results may suffer.

We have experienced periods of expansion, relative stability and contraction in our revenues and operations in the past. Such fluctuations have placed, and may
continue  to  place,  strains  on  our  management  systems,  infrastructure  and  other  resources.  Especially  during  growth  periods,  we  hire  additional  direct  sales,
professional  services  and  marketing  personnel  domestically  and  internationally,  acquire  complementary  businesses,  technologies  or  assets,  and  increase  our
investment in research and development. Our future operating results depend to a large extent on our ability to successfully implement such plans and manage such
investments. To do so successfully we must, among other things:

• manage our expenses in line with our operating plans and current business environment;
• maintain and enhance our operational, financial and management controls, reporting systems and procedures;
•
• manage operations in multiple locations and time zones; and
•

develop and deliver new solutions and enhancements to existing solutions efficiently and reliably.

integrate acquired businesses, technologies or assets;

We expect to incur costs associated with the investments made to support our business strategy before the anticipated benefits or the returns are realized, if any. If
we  are  unable  to  grow  our  business  or  manage  our  future  growth  effectively,  we  may  not  be  able  to  take  advantage  of  market  opportunities  or  develop  new
solutions  or  enhancements  to  existing  solutions.  We  may  also  fail  to  satisfy  customer  requirements,  maintain  quality,  execute  our  business  plan  or  respond  to
competitive pressures, which could result in lower revenue and a decline in the share price of our common stock.

Our revenue and operating results have fluctuated, and are likely to continue to fluctuate, making our quarterly results difficult to predict, which may cause us
to miss analyst expectations and may cause the price of our common stock to decline.

Our operating results have been and may continue to be difficult to predict, even in the near term, and are likely to fluctuate as a result of a variety of factors, many
of which are outside of our control.

Comparisons of our revenue and operating results on a period-to-period basis may not be meaningful. You should not rely on our past results as an indication of
our future performance. Each of the following factors, among others, could cause our operating results to fluctuate from quarter to quarter:

the financial health of our healthcare customers and budgetary constraints on their ability to upgrade their communications;
the availability of government funding for healthcare facilities operated by the United States federal, state and local governments;

•
•
• market acceptance of our Smartbadge and its impact on orders for our existing Badge and related software;
•
•
•
•
•
•

changes in the regulatory environment affecting our healthcare customers, including impediments to their ability to obtain reimbursement for their services;
our ability to expand our sales and marketing operations;
our ability to successfully integrate acquired businesses;
the announcement of new significant contracts or relationships;
the procurement and deployment cycles of our healthcare customers and the length of our sales cycles;
changes in how healthcare operating and capital budgets are administered within the enterprise;

changes in customer deployment timelines;
variations in the amount of orders booked in a prior quarter but not delivered until later quarters;
our mix of solutions and the varying revenue recognition rules that apply;
pricing, including discounts by us or our competitors;
our ability to expand into non-healthcare markets;
our ability to develop significant new reseller relationships and maintain existing reseller relationships;
the financial health of our resellers;
our ability to successfully deploy our solutions in a timely manner;
our ability to sell and integrate third-party products and services, and our customer’s satisfaction with those third-party products and services;
our ability to forecast demand and manage lead times for the manufacture of our solutions;
our ability to develop and introduce new solutions and features to existing solutions that achieve market acceptance;
the announcement of a new product, which may cause sales cycles to lengthen;
federal government shutdowns;

If  we  do  not  achieve  the  anticipated  strategic  or  financial  benefits  from  our  acquisitions  or  if  we  cannot  successfully  integrate  them,  our  business  and
operating results could be harmed.

We  have  acquired,  and  in  the  future  may  acquire,  complementary  businesses,  technologies  or  assets  that  we  believe  to  be  strategic.  We  may  not  achieve  the
anticipated  strategic  or  financial  benefits,  or  be  successful  in  integrating  any  acquired  businesses,  technologies  or  assets.  If  we  cannot  effectively  integrate  the
acquired business and products into our business, we may not achieve market acceptance for, or derive significant revenue from, these new solutions.

Integrating newly acquired businesses, technologies and assets could strain our resources, could be expensive and time consuming, and might not be successful.
Our recent acquisitions expose us, and we will be further exposed, if we acquire or invest in additional businesses, technologies or assets, to a number of risks,
including that we may:

•
•

•

•
•

•

•

experience technical issues as we integrate acquired businesses, technologies or assets into our existing solutions;
encounter difficulties leveraging our existing sales and marketing organizations, and direct sales channels, to increase our revenue from acquired businesses,
technologies or assets;
find that the acquisition does not further our business strategy, we overpaid for the acquisition or the economic conditions underlying our acquisition decision
have changed;
have difficulty retaining key personnel of acquired businesses;
suffer  disruption  to  our  ongoing  business  and  diversion  of  our  management’s  attention  as  a  result  of  transition  or  integration  issues  and  the  challenges  of
managing geographically or culturally diverse enterprises;
experience unforeseen and significant problems or liabilities associated with quality, technology and legal contingencies relating to the acquisition, such as
intellectual property or employment matters; and
incur substantial costs to integrate the acquired business.

If  we  were  to  proceed  with  one  or  more  additional  significant  acquisitions  in  which  the  consideration  included  cash,  we  could  be  required  to  use  a  substantial
portion of our available cash. To the extent we issue shares of capital stock or other rights to purchase capital stock, including options and warrants, the ownership
of  existing  stockholders  would  be  diluted.  In  addition,  acquisitions  may  result  in  the  incurrence  of  debt,  contingent  liabilities,  large  write-offs,  or  other
unanticipated costs, events or circumstances, any of which could harm our operating results.

In addition, from time to time we may enter into negotiations for acquisitions that are not ultimately consummated. These negotiations could result in significant
diversion of management time, as well as substantial out-of-pocket costs.

We  could  be  required  to  record  adjustments  to  our  recorded  asset  balance  for  intangible  assets,  including  goodwill,  that  could  significantly  impact  our
operating results.

Our balance sheet includes significant intangible assets, including goodwill and other acquired intangible assets. The determination of related estimated useful lives
and whether these assets have been impaired involves significant judgment and is subject to factors and events over which we have no control. The introduction of
new competitive  products  or services  into  our markets  could impair  the  value  of our  intangible  assets  if  they create  market  conditions  that  adversely  affect  the
competitiveness  of  our  products  and  services.  Further,  declines  in  our  market  capitalization  may  be  an  indicator  that  our  intangible  assets  or  goodwill  carrying
values exceed their fair values, which could lead to potential impairment charges that could impact our operating results.

Developments in the healthcare industry and governing regulations have negatively affected and may continue to negatively affect our business.

Substantially  all  of our revenue  is derived  from  customers  in the healthcare  industry,  in particular,  hospitals.  The healthcare  industry  is highly regulated  and is
subject to changing political, legislative, regulatory and other influences. Developments generally affecting the healthcare industry, including new regulations or
new  interpretations  of  existing  regulations,  could  adversely  affect  spending  on  information  technology  and  capital  equipment  by  reducing  funding,  changing
healthcare pricing or delivery or creating impediments for obtaining healthcare reimbursements, which together with declining admission trends, could cause our
sales to decline and negatively impact our business. For example, the margins of our hospital customers are modest, and potential decreases in reimbursement for
healthcare costs may reduce the overall solvency of our customers or cause further deterioration in their financial or business condition.

Since  2009,  three  significant  bills  were  signed  into  law  that  impact  the  U.S.  healthcare  system.    Those  bills  include  The  Health  Information  Technology  for
Economic and Clinical Health Act, enacted under Title XIII of the American Recovery and Reinvestment Act of 2009 (HITECH Act), the ACA, and the Health
Care  and  Education  Reconciliation  Act  of  2010.  Together,  these  acts  have  driven  substantive  changes  over  several  years  to  the  operating  processes,
reimbursements and rules governing the U.S. healthcare system. Further, the President of the United States and members of Congress have stated their intent to
significantly revise, repeal or reduce funding under the ACA. Uncertainty surrounding the status of the ACA and its regulations may impact the spending of our
healthcare  customers,  and  we  cannot  predict  the  effect  on  our  business  of  any  new  legislation  and  regulations  that  may  be  adopted  if  the  ACA is  significantly
changed or repealed.

We believe that our healthcare customers are unsure of the impact of the elements of those acts, as well as the related efforts to amend or repeal the ACA will have
on their business, and cannot predict the timing and requirements of the final rules issued by the U.S. Department of Health and Human Services (HHS) for these
statutes, making managing their business operations more difficult.  Further, as has been experienced since 2010, as rules and agency guidance pursuant to these
statutes are implemented and revised by HHS, a number of aspects of the acts have been interpreted, modified or delayed. For example, sudden changes in the rules
for individuals buying insurance through state or federal health insurance exchanges, and individual and employer mandates to have and offer insurance coverage,
had challenged hospitals’ abilities to forecast patient utilization and revenues, and to set operational plans and budget accordingly. We believe that it is likely that
additional legislative changes by Congress and rulemaking by HHS will continue.

Federal  budget  activities  also  impact  our  customers.  Our customers  include  healthcare  facilities  run  by  the  Department  of  Defense  and  the  U.S. Department  of
Veterans  Affairs.  During  the  years  ended  December  31,  2018  and  2017,  we  generated  approximately  18%  and  18%,  respectively  of  our  revenue  from  these
customers.  Our reseller  to the Department  of Defense and the U.S. Department  of Veterans  Affairs represented  26% and 27% of our accounts receivable  as of
December 31, 2018 and December 31, 2017, respectively. These customers have been and may continue to be impacted by budgetary and legislative actions.

On December 22, 2018, certain departments of the U.S. federal government ceased operating as a result of failure by the legislative and executive branches of the
government to pass bills to keep them operating. Although the congress passed a temporary operating budget, there is a risk that the government could be shut
down again. Any past or future shutdown may impact our US government customers’ spending decisions, as well as those of our non-US government customers.
Any reduction or delay in our customers’, or potential customers’ spending decisions may result in a delay, or reduction, to our revenue.

In addition, many state governments are changing or expanding their healthcare laws, adding additional complexity to understanding the potential impacts.

We are unable to predict the full impact of these new and changing rules on our hospital customers and others in the healthcare industry.  Impacts of these rules
have  affected  and  could  continue  to  affect  materially  our  customers’  ability  to  budget  for  or  purchase  our  products.  The  healthcare  industry  has  changed
significantly  in recent years and we expect that significant changes will continue to occur. We cannot provide assurance that the markets for our solutions will
continue to exist at current levels or that we will have adequate technical, financial and marketing resources to react to changes in those markets.

We primarily compete in the rapidly evolving and competitive healthcare market, and if we fail to effectively respond to competitive pressures, our business and
operating results could be harmed.

We believe that the primary competition for our solutions has consisted of traditional methods using wired and wireless phones, pagers and overhead intercoms.
While we believe that our system is superior to these legacy methods, our solutions require a significant infrastructure investment by a hospital and many hospitals’
spending is severely constrained by other priorities.

Manufacturers and distributors of product categories such as cellular phones, smartphone applications, pagers, mobile radios and in-building wireless telephones
also sell their products to hospitals as components of communication solutions. Of these product categories, in-building wireless telephones and pagers represent
the most significant current competition for the sale of our solutions.

16

Table of Contents

The market for in-building wireless phones is dominated by communications companies such as Cisco Systems, Ascom and Spectralink. In addition, the growing
proliferation  of  smartphones  and  related  applications,  including  cloud-based  applications,  represents  another  category  of  competitive  offerings.  Although  our
customers  value  secure  text-messaging  using  smartphones,  we  do  not  believe  most  of  our  potential  customers  would  consider  that  feature  alone  an  adequate
substitute  for  a  comprehensive  multi-mode  communication  solution.  Some  customers  may  choose  solutions  that  are  not  HIPAA-compliant,  given  their  budget
constraints. Furthermore, in clinical integrations and middleware we compete with companies including Connexall and Philips Healthcare.

While we do not currently have a directly comparable single competitor that provides a solution as richly-featured as Vocera’s solution for the healthcare market,
we  could  face  such  competition  in  the  future.  Potential  competitors  in  the  healthcare  or  communications  markets  include  large,  multinational  companies  with
significantly more resources to dedicate to product development and sales and marketing. These companies, which may include electronic health record vendors or
other large software companies, may have existing relationships within the hospital, which may enhance their ability to gain a foothold in our market. For example,
some of the electronic health record vendors have started to offer secure text messaging as an additional service and have said they plan to expand these offerings
to complete more directly with us. Customers may prefer to purchase a more highly integrated or bundled solution from a single provider or an existing supplier
rather  than  a  new  supplier,  regardless  of  performance  or  features.  Accordingly,  if  we  fail  to  effectively  respond  to  competitive  pressures,  we  could  experience
pricing pressure, reduced profit margins, higher sales and marketing expenses, lower revenue and the loss of market share, any of which would harm our business,
operating results or financial condition.

If we fail to increase market awareness of our brand and solutions, and expand our sales and marketing operations, our business could be harmed.

We intend to continue to add personnel and resources in sales and marketing as we focus on expanding awareness of our brand and solutions and capitalize on
sales opportunities with new and existing customers. Our efforts to improve sales of our solutions will result in an increase in our sales and marketing expense and
general and administrative expense, and these efforts may not be successful. Some newly hired sales and marketing personnel may subsequently be determined to
be unproductive and have to be replaced, resulting in operational and sales delays and incremental costs. If we are unable to significantly increase the awareness of
our brand and solutions or effectively manage the costs associated with these efforts, our business, financial condition and operating results could be harmed.

Failure to protect our information technology infrastructure against cyber-based attacks, network security breaches, service interruptions, or data corruption
could significantly disrupt our operations and adversely affect our business and operating results.

We rely  on information  technology  and telephone  networks  and systems,  including  the  Internet,  to process  and transmit  sensitive  electronic  information  and to
manage  or  support  a  variety  of  business  processes  and  activities,  including  sales,  billing,  customer  service,  procurement  and  supply  chain.  We  use  enterprise
information technology systems to record, process, and summarize financial information and results of operations for internal reporting purposes and to comply
with  regulatory  financial  reporting,  legal,  and  tax  requirements.  Our  information  technology  systems,  some  of  which  are  managed  by  third-parties,  may  be
susceptible  to  damage,  disruptions  or  shutdowns  due  to  computer  viruses,  attacks  by  computer  hackers,  failures  during  the  process  of  upgrading  or  replacing
software,  databases  or components  thereof,  power outages,  hardware  failures,  telecommunication  failures,  user errors  or catastrophic  events.  Although we have
developed systems and processes that are designed to protect confidential information and prevent data loss and other security breaches, including systems and
processes designed to reduce the impact of a security breach at a third-party vendor, such measures cannot provide absolute security. If our systems are breached or
suffer  severe  damage,  disruption  or  shutdown  and  we  are  unable  to  effectively  resolve  the  issues  in  a  timely  manner,  our  business  and  operating  results  may
significantly  suffer  and  we  may  be  subject  to  litigation,  government  enforcement  actions  or  potential  liability.  Security  breaches  could  also  cause  us  to  incur
significant  remediation  costs,  result  in  product  development  delays,  disrupt  key  business  operations,  adversely  impact  customer  relationships,  damage  our
reputation and divert attention of management and key information technology resources.

We depend on a number of sole source and limited source suppliers, and if we are unable to source our components from them, our business and operating
results could be harmed.

We depend on sole and limited source suppliers for several hardware components of our solutions, including our batteries and integrated circuits. We purchase
inventory generally through individual purchase orders. Any of these suppliers could cease production of our components, cease to provide the necessary levels of
support  for  our  use  of  their  components,  experience  capacity  constraints,  material  shortages,  work  stoppages,  financial  difficulties,  cost  increases  or  other
reductions or disruptions in output, cease operations or be acquired by, or enter into exclusive arrangements with, a competitor. These suppliers typically rely on
purchase orders rather than long-term contracts with their suppliers, and as a result, even if available, the supplier may not be able

17

Table of Contents

to secure sufficient materials at reasonable prices or of acceptable quality to build our components in a timely manner. Any of these circumstances could cause
interruptions or delays in the delivery of our solutions to our customers, and this may force us to seek components from alternative sources, which may not have
the required specifications, or be available in time to meet demand or on commercially reasonable terms, if at all. Any of these circumstances may also force us to
redesign our solutions if a component becomes unavailable in order to incorporate a component from an alternative source.

Our solutions incorporate multiple software components obtained from licensors on a non-exclusive basis, such as voice recognition software, software supporting
the runtime execution of our software platform, and database and reporting software. Our license agreements can be terminated for cause. In many cases, these
license agreements specify a limited term and are only renewable beyond that term with the consent of the licensor. If a licensor terminates a license agreement for
cause, objects to its renewal or conditions renewal on modified terms and conditions, we may be unable to obtain licenses for equivalent software components on
reasonable  terms  and  conditions,  including  licensing  fees,  warranties  or  protection  from  infringement  claims.  Some  licensors  may  discontinue  licensing  their
software  to  us  or  support  of  the  software  version  used  in  our  solutions.  In  such  circumstances,  we  may  need  to  redesign  our  solutions  at  substantial  cost  to
incorporate alternative software components or be subject to higher royalty costs. Any of these circumstances could adversely affect the cost and availability of our
solutions.

Third-party  licensors  generally  require  us  to  incorporate  specific  license  terms  and  conditions  in  our  agreements  with  our  customers.  If  we  are  alleged  to  have
failed to incorporate these license terms and conditions, we may be subject to claims by these licensors, incur significant legal costs defending ourselves against
such claims and, if such claims are successful, be subject to termination of licenses, monetary damages, or an injunction against the continued distribution of one or
more of our solutions.

Because we depend on contract manufacturers and original design manufacturers, our operations could be harmed and we could lose sales if we encounter
problems with these manufacturers.

We  do  not  have  internal  manufacturing  capabilities  and  rely  upon  two  contract  manufacturers,  Sercomm  and  SMTC,  to  make  our  wearable  devices,  we  have
entered into manufacturing agreements with Sercomm and SMTC that are terminable by either party with advance notice and that may also be terminated for a
material  uncured  breach.  We  expect  to enter  into  additional  contract  manufacturing  agreements  as  we expand  our  business.  We also  rely  on ODMs to  produce
accessories, including batteries, chargers and attachments. Any of these suppliers could cease production of our components, cease to provide the necessary levels
of  support  for  our  use  of  their  components,  experience  capacity  constraints,  material  shortages,  work  stoppages,  financial  difficulties,  cost  increases  or  other
reductions or disruptions in output, cease operations or be acquired by, or enter into exclusive arrangements with, a competitor. If Sercomm, SMTC, or another
contract manufacturer or an ODM is unable or unwilling to continue manufacturing components of our solutions in the volumes and timeframes that we require,
fails to meet our quality specifications or significantly increases its prices, we may not be able to deliver our solutions to our customers with the quantities, quality
and performance that they expect in a timely manner. As a result, we could lose sales and our operating results could be harmed.

Sercomm,  SMTC, other  contract  manufacturers  or  ODMs  may  experience  problems  that  could  impact  the  quantity  and  quality  of  hardware  components  of  our
solution, including disruptions in their manufacturing operations due to equipment breakdowns, labor strikes or shortages, component or material shortages and
cost  increases.  Sercomm,  SMTC,  other  contract  manufacturers  and  these  ODMs  generally  rely  on  purchase  orders  rather  than  long-term  contracts  with  their
suppliers, and as a result, may not be able to secure sufficient components or other materials at reasonable prices or of acceptable quality to build components of
our solutions in a timely manner. The majority of the hardware components of our solution are manufactured in Asia or Mexico, and adverse changes in political or
economic circumstances in those locations could also disrupt our supply and quality of components of our solutions. In addition, U.S. government officials have
recently changed and proposed additional changes in trade, fiscal or tax policies, and any such changes in the U.S. or in other countries from which we source
components of our products could adversely affect our business.

Companies  occasionally  encounter  unexpected  difficulties  in  ramping  up  production  of  new  products,  and  we  may  experience  such  difficulties  with  future
generations of our products. Sercomm, SMTC, other contract manufacturers and our ODMs also manufacture products for other companies. Generally, our orders
represent a relatively small percentage of the overall orders received by Sercomm, SMTC, other contract manufacturers and these ODMs from their customers;
therefore, fulfilling our orders may not be a priority in the event Sercomm, SMTC, other contract manufacturers or an ODM is constrained in its ability to fulfill all
of  its  customer  obligations.  In  addition,  if  Sercomm,  SMTC,  other  contract  manufacturers  or  an  ODM  is  unable  or  unwilling  to  continue  manufacturing
components  of  our  solutions,  we  may  have  to  identify  one  or  more  alternative  manufacturers.  The  process  of  identifying  and  qualifying  a  new  contract
manufacturer or ODM can be time consuming, and we may not be able to substitute suitable alternative manufacturers in a timely manner or at an acceptable cost.
Additionally,  transitioning  to  a  new  manufacturer  may  cause  us  to  incur  additional  costs  and  delays  if  the  new  manufacturer  has  difficulty  manufacturing
components of our solutions to our specifications or quality standards.

18

Table of Contents

If we fail to forecast our manufacturing requirements accurately, or fail to properly manage our inventory with our contract manufacturer, we could incur
additional costs and experience manufacturing delays, which can adversely affect our operating results.

We place orders with our contract  manufacturers,  including Sercomm and SMTC, and we and our contract manufacturers  place orders with suppliers based on
forecasts of customer demand. Because of our international low cost sourcing strategy, our lead times are long and cause substantially more risk to forecasting
accuracy  than  would  result  were  lead  times  shorter.  Our  forecasts  are  based  on  multiple  assumptions,  each  of  which  may  introduce  errors  into  our  estimates
affecting  our  ability  to  meet  our  customers’  demands  for  our  solutions.  We  also  may  face  additional  forecasting  challenges  due  to  new  product  introductions,
product transitions in the components of our solutions, or to our suppliers discontinuing production of materials and subcomponents required for our solutions. If
demand for our solutions increases significantly, we may not be able to meet demand on a timely basis, and we may need to expend a significant amount of time
working  with  our  customers  to  allocate  limited  supply  and  maintain  positive  customer  relations,  or  we  may  incur  additional  costs  in  order  to  source  additional
materials  and subcomponents to produce components of our solutions or to expedite the manufacture  and delivery  of additional inventory. If we underestimate
customer demand, our contract manufacturer  may have inadequate materials  and subcomponents on hand to produce components of our solutions, which could
result  in  manufacturing  interruptions,  shipment  delays,  deferral  or  loss  of  revenue,  and  damage  to  our  customer  relationships.  Conversely,  if  we  overestimate
customer  demand,  we  and  our  contract  manufacturers  may  purchase  more  inventory  than  required  for  actual  customer  orders,  resulting  in  excess  or  obsolete
inventory, thereby increasing our costs and harming our operating results.

If hospitals do not have and are not willing to install, upgrade and maintain the wireless infrastructure required to effectively operate our solutions, then they
may experience technical problems or not purchase our solutions at all.

The effectiveness  of our solutions depends upon the quality and compatibility  of the communications  environment that our healthcare customers maintain. Our
solutions require voice-grade wireless (Wi-Fi) installed through large enterprise environments, which can vary from hospital to hospital and from department to
department within a hospital. Many hospitals have not installed a voice-grade wireless infrastructure. If potential customers do not have a wireless network that can
properly and fully interoperate with our solutions, then such a network must be installed, or an existing Wi-Fi network must be upgraded or modified, for example,
by  adding  access  points  in  stairwells,  for  our  solutions  to  be  fully  functional.  The  additional  costs  of  installing  or  upgrading  a  Wi-Fi  network  may  dissuade
potential customers from installing our solutions. Furthermore, if changes to a customer’s physical or information technology environment cause integration issues
or degrade the effectiveness of our solutions, or if the customer fails to upgrade or maintain its environment as may be required for software releases or updates or
to  ensure  our  solution’s  effectiveness,  the  customer  may  not  be  able  to  fully  utilize  our  solutions  or  may  experience  technical  problems,  or  these  changes  may
impact the performance of other wireless equipment being used. If such circumstances arise, prospective customers may not purchase or existing customers may
not expand their use of or deploy upgraded versions of our solutions, thereby harming our business and operating results.

If we fail to achieve and maintain certification for certain U.S. federal standards, our sales to U.S. government customers will suffer.

We believe that a significant opportunity exists to continue to sell our products to healthcare facilities in the Veterans Administration and Department of Defense
(DoD). These customers require independent certification of compliance with specific requirements relating to encryption, security, interoperability and scalability,
including  Federal  Information  Processing  Standard  (FIPS)  140-2  and,  as  to  DoD,  certification  by  its  Joint  Interoperability  and  Test  Command  and  under  its
Information Assurance Certification and Accreditation Process. We have received certification under certain of these standards for military-specific configurations
of our solution incorporating our Badge, but we do not have these certifications for our new Smartbadge. We continue to carry out further compliance activities
and recertifications, as required. A failure on our part to achieve and maintain compliance and to respond to new threats and vulnerabilities, both as to current
products and as to new product versions, could adversely impact our revenue.

Our efforts to sell our solutions in non-healthcare markets may not be successful.

In  recent  years,  we  have  actively  engaged  in  sales  efforts  to  customers  outside  the  healthcare  markets,  including  hospitality,  energy  and  other  mobile  work
environments. We may not be successful in further penetrating the non-healthcare markets upon which we are initially focusing, or other new markets. To date, our
solutions have been selected by over 270 customers in non-healthcare markets. Total revenue from non-healthcare customers accounted for 3%, 3% and 3% of our
revenue  for  the  years  ended  December  31,  2018,  2017  and  2016,  respectively.  If  we  cannot  maintain  these  customers  by  providing  solutions  that  meet  their
requirements, if we cannot successfully expand our solutions in non-healthcare markets, or if adoption of our solutions remains slow, we may not obtain significant
revenue  from  these  markets.  We  may  experience  challenges  as we expand  in non-healthcare  markets,  including  pricing  pressure  on our solutions  and technical
issues as we adapt our solutions for the requirements of new markets. Our solutions

19

Table of Contents

also may not contain the functionality required by these non-healthcare markets or may be too expensive or may not sufficiently differentiate us from competing
solutions such that customers can justify deploying our solutions.

We generally recognize revenue from maintenance and support contracts and subscription arrangements over the contract term, and changes in sales may not
be immediately reflected in our operating results.

We generally recognize revenue from our customer maintenance and support contracts, extended warranty contracts and subscription arrangements ratably over the
contract term, which is typically 12 months, in some cases subject to an early termination right. Revenue from our maintenance and support contracts accounted for
35%, 32% and 33% of our revenue for the years ended December 31, 2018, 2017 and 2016, respectively. A portion of the revenue we report in each quarter is
derived from the recognition of deferred revenue relating to maintenance and support contracts entered into during previous quarters. Consequently, a decline in
new or renewed maintenance and support, extended warranty contracts or subscription agreements by our customers in any one quarter may not be immediately
reflected  in  our  revenue  for  that  quarter.  Such  a  decline,  however,  will  negatively  affect  our  revenue  in  future  quarters.  Accordingly,  the  effect  of  significant
downturns in sales and market acceptance of our services and potential changes in our rate of renewals may not be fully reflected in our operating results until
future periods.

Our success depends upon our ability to attract, integrate and retain key personnel, and our failure to do so could harm our ability to grow our business.

Our success depends, in part, on the continuing services of our senior management and other key personnel, and our ability to continue to attract, integrate and
retain  highly  skilled  personnel,  particularly  in  engineering,  sales  and  marketing.  Competition  for  highly  skilled  personnel  is  intense,  particularly  in  the  Silicon
Valley where our headquarters are located. If we fail to attract, integrate and retain key personnel, our ability to grow our business could be harmed.

The members of our senior management and other key personnel are at-will employees, and may terminate their employment at any time without notice. If one or
more members of our senior management terminate their employment, we may not be able to find qualified individuals to replace them on a timely basis or at all
and our senior management may need to divert their attention from other aspects of our business. Former employees may also become employees of a competitor.
We may also have to pay additional compensation to attract and retain key personnel. We also anticipate hiring additional engineering, marketing and sales, and
services personnel to grow our business. Often, significant amounts of time and resources are required to train these personnel. We may incur significant costs to
attract, integrate and retain them, and we may lose them to a competitor or another company before we realize the benefit of our investments in them.

Our international operations subject us, and may increasingly subject us in the future, to operational, financial, economic and political risks abroad.

Although we derive a relatively  small portion of our revenue  from  customers  outside  the United States,  we believe  that  non-U.S. customers  could represent  an
increasing share of our revenue in the future. During the years ended December 31, 2018, 2017 and 2016, we generated 10.2%, 10.2% and 10.4% of our revenue,
respectively, from customers outside of the United States, including Canada, the United Kingdom, Australia, New Zealand and Middle Eastern countries including
the  United  Arab  Emirates,  Saudi  Arabia  and  Qatar.  In  2014,  we  opened  a  new  innovation  center  in  India  and  a  sales  office  in  Dubai,  United  Arab  Emirates.
Accordingly, we are subject to risks and challenges that we would not otherwise face if we conducted our business solely in the United States, including:

•
•
•
•
•
•

•
•
•
•
•
•

challenges incorporating non-English speech recognition capabilities into our solutions as we expand into non-English speaking jurisdictions;
difficulties integrating our solutions with wireless infrastructures with which we do not have experience;
difficulties integrating local dialing plans and applicable PBX standards;
challenges associated with delivering support, training and documentation in several languages;
difficulties in staffing and managing personnel and resellers;
the  need  to  comply  with  a  wide  variety  of  foreign  laws  and  regulations,  including  increasingly  stringent  data  privacy  regulations,  requirements  for  export
controls for encryption technology, employment laws, changes in tax laws and tax audits by government agencies;
political and economic instability in, or foreign conflicts that involve or affect, the countries of our customers;
adverse effects on us directly, or on our customers and suppliers, of changes in trade, fiscal or tax policies, including the imposition of tariffs;
difficulties in collecting accounts receivable and longer accounts receivable payment cycles;
exposure to competitors who are more familiar with local markets;
risks associated with the Foreign Corrupt Practices Act and local anti-bribery law compliance;
difficulties associated with resolving contract disputes in foreign countries with varied legal systems;

•

limited or unfavorable intellectual property protection in some countries; and
currency exchange rate fluctuations, which could affect the price of our solutions relative to locally produced solutions.

Any of these factors could harm our existing international business, impair our ability to expand into international markets or harm our operating results.

Our solutions are highly complex and may contain software or hardware defects that could harm our reputation and operating results.

Our solutions  incorporate  complex  technology,  are  deployed  in a variety  of  complex  hospital  environments  and must interoperate  with  many different  types of
devices and hospital systems. While we test the components of our solutions for defects and errors prior to release, we or our customers may not discover a defect
or error  until  after  we have deployed  our solution,  integrated  it into the hospital  environment  and our customer  has commenced  general  use of the solution.  In
addition, our solutions in some cases are integrated with hardware and software offered by “middleware” vendors in order to interoperate with nurse call systems,
device  alarms  and  other  hospital  systems.  Our  software  may  also  be  deployed  on  third  party  devices,  including  devices  we  resell,  which  creates  additional
complexity because we share control of the customer experience. If we cannot successfully integrate our solutions with these vendors as needed or if any hardware
or software of these vendors, contains any defect or error, then our solutions may not perform as designed, or may exhibit a defect or error.

Any defects or errors in, or which are attributed to our solutions, or to products or services we resell, could result in:
•
•
•
•
•
•
•
•

delayed market acceptance of our affected solutions;
loss of revenue or delay in revenue recognition;
loss of customers or inability to attract new customers;
diversion of engineering or other resources for remedying the defect or error;
damage to our brand and reputation;
delay in delivery of information;
increased service and warranty costs, including potential replacement costs for product recalls or returns; and
legal actions by our customers and hospital patients, including product liability claims.

If any of these occur, our operating results and reputation could be harmed.

We face potential liability related to the privacy and security of personal information collected through our solutions.

In  connection  with  our  healthcare  business,  we  handle  and  have  access  to  personal  health  information  subject  in  the  United  States  to  the  Health  Insurance
Portability and Accountability Act of 1996 (HIPAA) or HITECH, regulations issued pursuant to these statutes, state privacy and security laws and regulations, and
associated  contractual  obligations  as  a  “business  associate”  of  healthcare  providers.  These  statutes,  regulations  and  contractual  obligations  impose  numerous
requirements regarding the use and disclosure of personal health information with which we must comply. Our failure to accurately anticipate the application or
interpretation of these statutes, regulations and contractual obligations as we develop our solutions, a failure by us to comply with their requirements (e.g., evolving
encryption and security requirements)  or an allegation that defects in our products have resulted in noncompliance by our customers could create material civil
and/or criminal liability for us, resulting in adverse publicity and negatively affecting our business.

In addition, the use and disclosure of personal health information is subject to laws and regulations in other jurisdictions in which we do business or expect to do
business  in  the  future.  Any  developments  stemming  from  enactment  or  modification  of  these  laws  and  regulations,  or  the  failure  by  us  to  comply  with  their
requirements or to accurately anticipate the application or interpretation of these laws could create material liability to us, result in adverse publicity and negatively
affect our business.

For example, the European Union previously adopted the Data Protection Directive (DPD), imposing strict regulations and establishing a series of requirements
regarding the storage of personally identifiable information on computers or recorded on other electronic media. This has been implemented by all EU member
states through national laws. DPD provides for specific regulations requiring all non-EU countries doing business with EU member states to provide adequate data
privacy protection when receiving personal data from any of the EU member states. In May 2016, the EU formally adopted the General Data Protection Regulation
(GDPR),  which  applied  to  all  EU  member  states  starting  in  May  2018  and  replaced  the  current  DPD.  The  GDPR  regulation  introduces  new  data  protection
requirements in the EU and substantial fines for breaches of the data protection rules. It increased our responsibility and liability in relation to personal data that we
process and we were required to put in place additional mechanisms ensuring compliance with the new EU data protection rules.  Additionally, Canada’s Personal
Information and Protection of Electronic Documents Act, as well as a variety of provincial statutes, provides Canadian residents with privacy protections in regard
to transactions with businesses and organizations in the private sector and sets out ground rules for how private sector organizations may collect, use and disclose
personal information in the course of commercial activities. A finding

21

Table of Contents

that we have failed to comply with applicable laws and regulations regarding the collection, use and disclosure of personal information could create liability for us,
result in adverse publicity and negatively affect our business.

Any legislation or regulation in the area of privacy and security of personal information could affect the way we operate our services and could harm our business.
For example, the European Court of Justice invalidated the U.S.-EU Safe Harbor framework that had been in place since 2000, which allowed companies to meet
certain EU legal requirements for the transfer of personal data from the European Economic Area to the United States. While other adequate legal mechanisms to
lawfully transfer such data remain, the invalidation of the U.S.-EU Safe Harbor framework may result in different European data protection regulators applying
differing standards for the transfer of personal data, which could result in increased regulation, cost of compliance and limitations on data transfer for us and our
customers. The costs of compliance with, and the other burdens imposed by, these and other laws or regulatory actions may prevent us from selling our solutions or
increase  the  costs  associated  with  selling  our  solutions,  and  may  affect  our  ability  to  invest  in  or  jointly  develop  solutions  in  the  United  States  and  in  foreign
jurisdictions.  Further,  we  cannot  assure  you  that  our  privacy  and  security  policies  and  practices  will  be  found  sufficient  to  protect  us  from  liability  or  adverse
publicity relating to the privacy and security of personal information.

The failure of our equipment lease customers to pay us under leasing agreements with them that we do not sell to third party lease finance companies could
harm our revenue and operating results.

In 2012, we began offering our solutions to our customers through multi-year equipment lease agreements. In connection with each sale, we recognize product-
related  revenue  at  the  net  present  value  of  the  lease  payment  stream  once  our  obligations  related  to  such  sale  have  been  met.  We  sell  the  bulk  of  these  leases,
including the related accounts receivables, to third party lease finance companies on a non-recourse basis. We will have to retain unsold leases in-house, which will
expose  us  to  the  creditworthiness  of  such  lease  customers  over  the  lease  term.  For  the  leases  that  we  retain  in-house,  our  ability  to  collect  payments  from  a
customer or to recognize revenue for the sale could be impaired if the customer fails to meet its obligations to us such as in the case of its bankruptcy filing or
deterioration in its financial position, or has other creditworthiness issues, any of which could harm our revenue and operating results.

22

If our efforts to protect the security of information collected by our customers are unsuccessful, we could become subject to costly government enforcement
actions and private litigation, and our sales and reputation could suffer.

The  nature  of  our  business  involves  the  receipt  and  storage  of  information  about  our  customers.  We  have  implemented  programs  to  detect  and  alert  us  to  data
security incidents. However, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and may
be  difficult  to  detect  for  long  periods  of  time,  we  may  be  unable  to  anticipate  these  techniques  or  implement  adequate  preventive  measures.  Companies  are
increasingly subject to a wide variety of security incidents, cyber-attacks and other attempts to gain unauthorized access. These threats can come from a variety of
sources, ranging in sophistication from an individual hacker to malfeasance by employees, consultants or other service providers to state-sponsored attacks. Cyber
threats  may  be  generic,  or  they  may  be  custom-crafted  against  our  information  systems.  In  recent  times,  cyber-attacks  have  become  more  prevalent  and  much
harder to detect and defend against. Our network and storage applications may be vulnerable to cyber-attack, malicious intrusion, malfeasance, loss of data privacy
or  other  significant  disruption  and  may  be  subject  to  unauthorized  access  by  hackers,  employees,  consultants  or  other  service  providers.  In  addition,  hardware,
software  or  applications  we  develop  or  procure  from  third  parties  may  contain  defects  in  design  or  manufacture  or  other  problems  that  could  unexpectedly
compromise  information  security.  Unauthorized  parties  may  also  attempt  to  gain  access  to  our  systems  or  facilities  through  fraud,  trickery  or  other  forms  of
deceiving  our  employees,  contractors  and  temporary  staff.  If  we  experience  significant  data  security  breaches  or  fail  to  detect  and  appropriately  respond  to
significant data security breaches, we could be exposed to government enforcement actions and private litigation, as well as potentially incur significant costs and
diversion  of  resources  to  comply  with  our  contractual  obligations  to  notify  our  customers  of  such  security  breaches,  particularly  with  respect  to  any  protected
health information  affected.  In addition, our customers could lose confidence  in our ability  to protect their information,  which could cause them to discontinue
using our products or purchasing from us altogether.

Our use of open source and non-commercial software components could impose risks and limitations on our ability to commercialize our solutions.

Our solutions contain software modules licensed under open source and other types of non-commercial licenses, including the GNU Public License, the Apache
License and others. We also may incorporate open source and other licensed software into our solutions in the future. Use and distribution of such software may
entail  greater  risks  than  use  of  third-party  commercial  software,  as  licenses  of  these  types  generally  do  not  provide  warranties  or  other  contractual  protections
regarding infringement claims or the quality of the code. Some of these licenses require the release of our proprietary source code to the public if we combine our
proprietary software with open source software in certain manners. This could allow competitors to create similar products with lower development effort and time
and ultimately result in a loss of sales for us.

The terms of many open source and other non-commercial licenses have not been judicially interpreted and there is a risk that such licenses could be construed in a
manner that could impose unanticipated conditions or restrictions on our ability to commercialize our solutions. In such event, in order to continue offering our
solutions, we could be required to seek licenses from alternative licensors, which may not be available on a commercially reasonable basis or at all, to re-engineer
our solutions or to discontinue the sale of our solutions in the event we cannot obtain a license or re-engineer our solutions on a timely basis, any of which could
harm  our  business  and  operating  results.  In  addition,  if  an  owner  of  licensed  software  were  to  allege  that  we  had  not  complied  with  the  conditions  of  the
corresponding license agreement, we could incur significant legal costs defending ourselves against such allegations. In the event such claims were successful, we
could be subject to significant damages, be required to disclose our source code, or be enjoined from the distribution of our solutions.

Claims of intellectual property infringement could harm our business.

Vigorous protection and pursuit of intellectual property rights has resulted in protracted and expensive litigation for many companies in our industry. Although
claims  of  this  kind  have  not  materially  affected  our  business  to  date,  there  can  be  no  assurance  of  the  absence  of  such  claims  in  the  future.  Any  claims  or
proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in
the diversion of significant operational resources, or require us to enter into royalty or licensing agreements, any of which could harm our business and operating
results.

Intellectual property lawsuits are subject to inherent uncertainties due to the complexity of the technical issues involved, and we cannot be certain that we will be
successful in defending ourselves against intellectual property claims. In addition, we currently have a limited portfolio of issued patents compared to many other
industry participants, and therefore may not be able to effectively utilize our intellectual property portfolio to assert defenses or counterclaims in response to patent
infringement claims or litigation brought against us by third parties. Further, we are a party to litigation with a patent holding company and it is possible that we
will be subject to future litigation with similar entities and other adverse patent owners who have no relevant products and against whom our potential patents may
provide little or no deterrence.

23

Table of Contents

Many potential litigants have the capability to dedicate substantially greater resources to enforce their intellectual property rights and to defend claims that may be
brought  against  them.  Furthermore,  a  successful  claimant  could  secure  a  judgment  that  requires  us  to  pay  substantial  damages  or  prevents  us  from  distributing
certain solutions or performing certain services. We might also be required to seek a license and pay royalties for the use of such intellectual property, which may
not  be  available  on  commercially  acceptable  terms  or  at  all.  Alternatively,  we  may  be  required  to  develop  non-infringing  technology,  which  could  require
significant effort and expense and may ultimately not be successful.

If we are unable to 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 protect our proprietary technology through patent, copyright, trade secret and
trademark laws in the United States and similar laws in other countries. We also protect our proprietary technology through licensing agreements, nondisclosure
agreements and other contractual provisions. These protections may not be available in all cases or may be inadequate to prevent our competitors from copying,
reverse engineering or otherwise obtaining and using our technology, proprietary rights or solutions in an unauthorized manner. The laws of some foreign countries
may  not  be  as  protective  of  intellectual  property  rights  as  those  in  the  United  States,  and  mechanisms  for  enforcement  of  intellectual  property  rights  may  be
inadequate. In addition, third parties may seek to challenge, invalidate or circumvent our patents, trademarks, copyrights and trade secrets, or applications for any
of the foregoing. Our competitors may independently develop technologies that are substantially equivalent, or superior, to our technology or design around our
proprietary rights. In each case, our ability to compete could be significantly impaired.

To prevent unauthorized use of our intellectual property rights, it may be necessary to prosecute actions for infringement or misappropriation of our proprietary
rights. Any such action could result in significant costs and diversion of our resources and management’s attention, and there can be no assurance that we will be
successful in such action. Furthermore, many of our current and potential competitors have the ability to dedicate substantially greater resources to enforce their
intellectual property rights than us. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing or misappropriating our intellectual
property. While we plan to continue to protect our intellectual property with, among other things, patent protection, there can be no assurance that:

•
•
•
•

current or future U.S. or foreign patent applications will be approved;
our issued patents will protect our intellectual property and not be held invalid or unenforceable if challenged by third parties;
we will succeed in protecting our technology adequately in all key jurisdictions in which we develop technology, or we or our competitors operate; or
others will not independently develop similar or competing products or methods or design around any patents that may be issued to us.

Our failure to obtain patents with claims of a scope necessary to cover our technology, or the invalidation of our patents, or our inability to protect any of our
intellectual property, may weaken our competitive position and harm our business and operating results. We might be required to spend significant resources to
monitor  and  protect  our  intellectual  property  rights.  We  may  initiate  claims  or  litigation  against  third  parties  for  infringement  of  our  proprietary  rights  or  to
establish the validity of our proprietary rights. Any litigation,  whether or not it is resolved in our favor, could result in significant expense to us and divert the
efforts of our technical and management personnel, which may harm our business, operating results and financial condition.

Product liability or other liability claims could cause us to incur significant costs, adversely affect the sales of our solutions and harm our reputation.

Our solutions are utilized by healthcare professionals and others in the course of providing patient care. As a result patients, family members, physicians, nurses or
others may allege we are responsible for harm to patients or healthcare professionals due to defects in, the malfunction of, the characteristics of, or the operation of,
our solutions. Any such allegations could harm our reputation and ability to sell our solutions.

Our solutions utilize lithium-ion batteries and electronic components that may overheat or otherwise malfunction as a result of physical or environmental damage.
Components  of  our  solutions  emit  radio  frequency  (RF)  emissions  which  have  been  alleged,  in  connection  with  cellular  phones,  to  have  adverse  health
consequences. Magnets in our badges may emit electromagnetic radiation and may be alleged to interfere with implanted medical or other devices. While these
components of our solutions comply with applicable guidelines, some may allege that these components of our solutions cause adverse health consequences. Also,
applicable  guidelines  may  change  making  these  components  of  our  solutions  non-compliant.  Any  such  allegations  or  non-compliance,  or  any  regulatory
developments, could negatively impact the sales of our solutions, require costly modifications to our solutions, and harm our reputation.

24

Table of Contents

Although our customer agreements contain terms and conditions, including disclaimers of liability, that are intended to reduce or eliminate our potential liability,
we could be required to spend significant amounts of management time and resources to defend ourselves against product liability, tort, warranty or other claims. If
any such claims were to prevail, we could be forced to pay damages, comply with injunctions or stop distributing our solutions. Even if potential claims do not
result in liability to us, investigating and defending against these claims could be expensive and time consuming and could divert management’s attention away
from our business. We maintain general liability insurance coverage, including coverage for errors and omissions; however, this coverage may not be sufficient to
cover large claims against us or otherwise continue to be available on acceptable terms. Further, the insurer could attempt to disclaim coverage as to any particular
claim.

We may require additional capital to support our business growth, and such capital may not be available.

We intend to continue to make investments to support business growth and may require additional funds to respond to business challenges, which include the need
to  develop  new  solutions  or  enhance  existing  solutions,  enhance  our  operating  infrastructure,  expand  our  sales  and  marketing  capabilities,  expand  into  non-
healthcare markets, and acquire complementary businesses, technologies or assets. Accordingly, we may need to engage in additional equity or debt financing to
secure funds. Equity and debt financing, however, might not be available when needed or, if available, might not be available on terms satisfactory to us. If we
raise  additional  funds  through  equity  financing,  our  stockholders  may  experience  dilution.  Debt  financing,  if  available,  may  involve  covenants  restricting  our
operations or our ability to incur additional debt. If we are unable to obtain adequate financing or financing on terms satisfactory to us in the future, our ability to
continue  to  support  our  business  growth  and  to  respond  to  business  challenges  could  be  significantly  limited  as  we  may  have  to  delay,  reduce  the  scope  of  or
eliminate some or all of our initiatives, which could harm our operating results.

Some of our solutions are, and others could become, subject to regulation by the U.S. Food and Drug Administration or similar foreign agencies, which could
increase our operating costs.

We provide certain products that are, and others that may become, subject to regulation by the Food and Drug Administration (FDA) and similar agencies in other
countries, or the jurisdiction of these agencies could be expanded in the future to include our solutions. The FDA regulates certain products, including software-
based products, as “medical devices” based, in part, on the intended use of the product and the risk the device poses to the patient should the device fail to perform
properly.  For  example,  the  clinical  alert  notification  solution  we  acquired  as  part  of  our  acquisition  of  Extension  Healthcare  and  the  clinical  communications
product we acquired from mVisum are regulated by the FDA as Class II medical devices. Although we have concluded that our wireless badge is a general-purpose
communications device not subject to FDA regulation, the FDA could disagree with our conclusion, or changes in our solutions or the FDA’s evolving regulation
could  lead  to  FDA  regulation  of  our  solutions.  Any  of  our  products  deemed  to  be  medical  devices  would  be  subject  to  the  2.3%  excise  tax  under  the  ACA;
however,  currently  there  is  a  moratorium  on  the  medical  device  tax  until  January  1,  2020.  Canada  and  many  other  countries  in  which  we  sell  or  may  sell  our
solutions  could  also  have  similar  regulations  applicable  to  our  solutions,  some  of  which  may  be  subject  to  change  or  interpretation.  We  may  incur  substantial
operating costs if we are required to register our solutions or components of our solutions as regulated medical devices under U.S. or foreign regulations, obtain
premarket  approval  from  the  FDA  or  foreign  regulatory  agencies,  and  satisfy  the  extensive  reporting  requirements.  In  addition,  failure  to  comply  with  these
regulations could result in enforcement actions and monetary penalties.

Our business is subject to the risks of earthquakes, fire, floods and other natural catastrophic events, and to interruption by man-made problems such as power
disruptions or terrorism.

Our corporate  headquarters  are  located  in the San  Francisco  Bay Area,  a region  known for seismic  activity,  and many critical  components  of our  solutions  are
sourced  in  Asia  and  Mexico,  regions  known  to  suffer  natural  disasters.  A  significant  natural  disaster,  such  as  an  earthquake,  fire  or  a  flood,  occurring  at  our
headquarters, our other facilities or where our contract manufacturer or its suppliers are located, could harm our business, operating results and financial condition.
In addition, acts of terrorism could cause disruptions in our business, the businesses of our customers and suppliers, or the economy as a whole. We also rely on
information technology systems to communicate among our workforce located worldwide, and in particular, our senior management, general and administrative,
and  research  and  development  activities  that  are  coordinated  with  our  corporate  headquarters  in  the  San  Francisco  Bay  Area.  Any  disruption  to  our  internal
communications, whether caused by a natural disaster or by man-made problems, such as power disruptions, in the San Francisco Bay Area, Asia or Mexico could
delay our research and development efforts, cause delays or cancellations of customer orders or delay deployment of our solutions, which could harm our business,
operating results and financial condition.

If we do not maintain effective internal control over financial reporting or disclosure controls and procedures in the future, the accuracy and timeliness of our
financial reporting may be adversely affected.

25

Table of Contents

The  Sarbanes-Oxley  Act  requires,  among  other  things,  that  we  assess  the  effectiveness  of  our  internal  control  over  financial  reporting  annually  and  disclosure
controls and procedures quarterly. In particular, we must obtain confidence in our internal control over financial reporting to allow management to report on the
effectiveness of our internal control over financial reporting as required by Section 404 of the Sarbanes-Oxley Act. To the extent we find a material weakness or
other deficiency in our internal control over financial reporting, the accuracy and timeliness of our financial reporting may be adversely affected.

Multiple negative consequences could ensue if a material weakness in our internal control over financial reporting is identified in the future, or we are not able to
comply with the requirements of Section 404 in a timely manner, or we do not maintain effective controls. For example, our reported financial results could be
materially misstated or could be restated, we could receive an adverse opinion regarding our controls from our independent registered public accounting firm, or
we could be subject to investigations or sanctions by regulatory authorities. All of these outcomes would require additional financial and management resources,
and the market price of our stock could decline.

We  will  continue  to  incur  substantial  costs  as  a  result  of  operating  as  a  public  company  and  our  management  devotes  substantial  time  to  public  company
compliance obligations.

As  a  public  company,  we  incur  substantial  legal,  accounting  and  other  expenses.  The  Sarbanes-Oxley  Act,  Dodd-Frank  Wall  Street  Reform  and  Consumer
Protection  Act  of  2010  and  rules  subsequently  implemented  by  the  SEC  and  our  stock  exchange,  impose  various  requirements  on  public  companies,  including
certain corporate governance practices. Our management and other personnel devote a substantial amount of time to these compliance requirements. Moreover,
these rules and regulations, along with compliance with accounting principles and regulatory interpretations of such principles, as amended by the JOBS Act, have
increased and will continue to increase our legal, accounting and financial compliance costs and have made and will continue to make some activities more time-
consuming and costly.

We face risks related to securities litigation that could result in significant legal expenses and settlement or damage awards.

We have in the past been, and may in the future become, subject to claims and litigation alleging violations of the securities laws or other related claims, which
could harm our business and require us to incur significant costs. For example, a purported securities class action was filed in August 2013 in the United States
District  Court  for  the  Northern  District  of  California  against  us  and  certain  of  our  officers  and  directors.  The  suit  purported  to  allege  claims  for  allegedly
misleading  statements  regarding  our  business  and  financial  results.  This  suit  was  settled  in  2016.  The  settlement,  which  called  for  payment  of  $9  million,  was
funded entirely and directly by our insurance carriers and paid during the three months ended September 30, 2016. Regardless of the outcome, these matters or
future litigation may require significant attention from management and could result in significant legal expenses, settlement costs or damage awards that could
have a material impact on our financial position, results of operations and cash flows.

The  SEC  “conflict  minerals”  rule  has  caused  us  to  incur  additional  expenses,  could  limit  the  supply  and  increase  the  cost  of  certain  metals  used  in
manufacturing our products and could make us less competitive in our target markets.

We are required to disclose the origin, source and chain of custody of specified minerals, known as conflict minerals, that are necessary to the functionality or
production  of  products  manufactured  or  contracted  to  be  manufactured.  The  SEC  requires  companies  to  obtain  sourcing  data  from  suppliers,  engage  in  supply
chain due diligence and file annually with the SEC a specialized disclosure report on Form SD covering the prior calendar year. The rule could limit our ability to
source at competitive prices and to secure sufficient quantities of certain minerals used in the manufacture of our products, as the number of suppliers that provide
conflict-free minerals may be limited. In addition, we have incurred, and may continue to incur, costs associated with complying with the rule, such as costs related
to auditing our compliance with the rules, costs related to the determination of the origin, source and chain of custody of the minerals used in our products, the
adoption  of  conflict  minerals-related  governance  policies,  processes  and  controls  and  possible  changes  to  products  or  sources  of  supply  as  a  result  of  such
activities. Within our supply chain, we may not be able to sufficiently verify the origins of the relevant minerals used in our products through the data collection
and due diligence procedures that we implement, which may harm our reputation. Furthermore, we may encounter challenges in satisfying those customers that
require that all of the components of our products be certified as conflict free, and if we cannot satisfy these customers, they may choose a competitor’s products.
We continue to investigate the presence of conflict materials within our supply chain.

Risks Related to the Notes

We have indebtedness in the form of convertible senior notes.

26

Table of Contents

As  a  result  of  the  Notes  offering,  we  incurred  $143.75  million  principal  amount  of  indebtedness,  the  principal  amount  of  which  we  may  be  required  to  pay  at
maturity in 2023. Holders of the Notes will have the right to require us to repurchase their Notes upon the occurrence of a “fundamental change” (as defined in the
indenture governing the Notes) at a purchase price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest, if any. In
addition, the indenture for the Notes provides that we are required to repay amounts due under the indenture in the event that there is an event of default for the
Notes that results in the principal, premium, if any, and interest, if any, becoming due prior to maturity date of the Notes. There can be no assurance that we will be
able to repay this indebtedness when due, or that we will be able to refinance this indebtedness on acceptable terms or at all. In addition, this indebtedness could,
among other things:

• heighten our vulnerability to adverse general economic conditions and heightened competitive pressures;
• require us to dedicate a larger portion of our cash flow from operations to interest payments, limiting the availability of cash for other purposes;
• limit our flexibility in planning for, or reacting to, changes in our business and industry; and
• impair our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other

purposes.

In  addition,  our  ability  to  purchase  the  Notes  or  repay  prior  to  maturity  any  accelerated  amounts  under  the  Notes  upon  an  event  of  default  or  pay  cash  upon
conversions  of  the  Notes  may  be  limited  by  law,  by  regulatory  authority  or  by  agreements  governing  our  indebtedness  outstanding  at  the  time.  Our  failure  to
repurchase Notes at a time when the repurchase is required by the indenture (whether upon a fundamental change or otherwise under the indenture) or pay cash
payable on future conversions of the Notes (unless we elect to deliver solely shares of our common stock to settle such conversion) as required by the indenture
would  constitute  a  default  under  the  indenture.  A  default  under  the  indenture  or  the  fundamental  change  itself  could  also  lead  to  a  default  under  agreements
governing any future indebtedness. If the repayment of any related indebtedness were to be accelerated after any applicable notice or grace periods, we may not
have sufficient funds to repay the indebtedness, repurchase the Notes or make cash payments upon conversions thereof.

Provisions in the indenture for the notes may deter or prevent a business combination that may be favorable to you.

If a fundamental change occurs prior to the maturity date of the Notes, holders of the Notes will have the right, at their option, to require us to repurchase all or a
portion  of  their  Notes.  In  addition,  if  a  make-whole  fundamental  change  occurs  prior  to  the  maturity  date,  we  will  in  some  cases  be  required  to  increase  the
conversion  rate  for  a  holder  that  elects  to  convert  its notes  in  connection  with such  make-whole  fundamental  change.  Furthermore,  the  indenture  for the  Notes
prohibits us from engaging in certain mergers or acquisitions unless, among other things, the surviving entity assumes our obligations under the Notes. These and
other provisions in the indenture could deter or prevent a third party from acquiring us even when the acquisition may be favorable to our stockholders.

The accounting method for convertible debt securities that may be settled in cash, such as the Notes, could have a material effect on our reported financial
results.

Under Accounting Standards Codification 470-20, Debt with Conversion and Other Options (ASC 470-20), an entity must separately account for the liability and
equity components of the convertible debt instruments (such as the Notes) that may be settled entirely or partially in cash upon conversion in a manner that reflects
the  issuer’s  economic  interest  cost.  The  effect  of  ASC  470-20  on  the  accounting  for  the  Notes  is  that  the  equity  component  is  required  to  be  included  in  the
additional paid-in capital section of stockholders’ equity on our consolidated balance sheet at the issuance date and the value of the equity component would be
treated as debt discount for purposes of accounting for the debt component of the Notes. We are required to record a non-cash interest expense for the amortization
of this debt discount for the term of the Notes which will adversely affect our financial results while the Notes are outstanding.

In  addition,  under  certain  circumstances,  convertible  debt  instruments  (such  as  the  Notes)  that  may  be  settled  entirely  or  partly  in  cash  may  be  accounted  for
utilizing  the  treasury  stock  method,  the  effect  of  which  is  that  the  shares  issuable  upon  conversion  of  such  Notes  are  not  included  in  the  calculation  of  diluted
earnings  per  share  except  to  the  extent  that  the  conversion  value  of  such  Notes  exceeds  their  principal  amount.  Under  the  treasury  stock  method,  for  diluted
earnings  per  share  purposes,  the  transaction  is  accounted  for  as  if  the  number  of  shares  of  common  stock  that  would  be  necessary  to  settle  such  excess,  if  we
elected to settle such excess in shares, are issued. We cannot be sure that the accounting standards in the future will continue to permit the use of the treasury stock
method. If we are unable, or otherwise elect not to, use the treasury stock method in accounting for the shares issuable upon conversion of the Notes, then our
diluted earnings per share could be adversely affected.

The capped call transactions may affect the value of the Notes and our common stock.

27

Table of Contents

In connection with the issuance of the Notes, we entered into capped call transactions with certain financial institutions (the option counterparties). The capped call
transactions are expected generally to reduce the potential dilution upon any conversion of the Notes and/or offset any cash payments we are required to make in
excess of the principal amount upon conversion of the Notes, with such reduction and/or offset subject to a cap. In connection with establishing their initial hedges
of  the  capped  call  transactions,  the  option  counterparties  and/or  their  respective  affiliates  purchased  shares  of  our  common  stock  and/or  entered  into  various
derivative  transactions  with  respect  to  our  common  stock.  This  activity  could  have  increased  (or  reduced  the  size  of  any  decrease  in)  the  market  price  of  our
common stock or the Notes at that time. In addition, the option counterparties and/or their respective affiliates may modify their hedge positions by entering into or
unwinding various derivatives with respect to our common stock and/or purchasing or selling our common stock in secondary market transactions (and are likely to
do so during any observation period related to a conversion of notes or following any repurchase of notes by us on any fundamental change repurchase date or
otherwise). This activity could also cause or avoid an increase or a decrease in the price of our common stock or the Notes. The potential effect, if any, of these
transactions and activities on the price of our common stock or the Notes will depend in part on market conditions and cannot be ascertained at this time. Any of
these activities could adversely affect the value of our common stock.

Risks related to our common stock

The market price of our common stock has been, and may continue to be, volatile, and your investment in our stock could suffer a decline in value.

There  has  been  significant  volatility  in  the  market  price  and  trading  volume  of  equity  securities,  which  is  often  unrelated  or  disproportionate  to  the  financial
performance of the companies issuing the securities. These broad market fluctuations may negatively affect the market price of our common stock. The market
price of our common stock could fluctuate significantly in response to the factors described in this “Risk Factors” section and elsewhere in this Form 10-K and
other factors, many of which are beyond our control, including:

•
•
•
•

•
•

•
•
•
•
•
•
•
•
•
•
•
•
•

actual or anticipated variation in anticipated operating results of us or our competitors;
the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;
announcements by us or our competitors of new solutions, new or terminated significant contracts, commercial relationships or capital commitments;
changes in the regulatory environment affecting our healthcare customers, including impediments to their ability to obtain reimbursement for their services,
and other actual or anticipated legal or regulatory developments in the United States or foreign countries;
actual or anticipated developments in our competitors’ businesses or the competitive landscape generally;
failure of securities analysts to maintain coverage of us, changes in financial estimates by any securities analysts who follow our company, or our failure to
meet these estimates or the expectations of investors;
developments or disputes concerning our intellectual property or other proprietary rights;
commencement of, or our involvement in, litigation;
announced or completed acquisitions of businesses, technologies or assets by us or our competitor;
changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular;
price and volume fluctuations attributable to inconsistent trading volume levels of our common stock;
our decision to seek additional equity or debt financing;
our public float relative to the total number of shares of our common stock that are issued and outstanding;
price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole;
rumors and market speculation involving us or other companies in our industry;
the dissemination of adverse or misleading reports or opinions about our business;
any major change in our management;
unfavorable economic conditions and slow or negative growth of our markets; and
other events or factors, including those resulting from war or incidents of terrorism.

If securities or industry analysts issue an adverse or misleading opinion regarding our stock or do not publish research or reports about our business, our stock
price could decline.

The trading market for our common stock depends in part on the research and reports that securities or industry analysts publish about us and our business. We do
not control these analysts or the content and opinions included in their reports. The price of our common stock could decline if one or more analysts downgrade our
common stock or if those analysts issue other unfavorable commentary or cease publishing reports about us or our business. If one or more analysts cease coverage
of our company or fail

28

Table of Contents

to  regularly  publish  reports  about  our  company,  we  could  lose  visibility  in  the  financial  market,  which  in  turn  could  cause  our  stock  price  to  decline.  Further,
securities or industry analysts may elect not to provide research coverage of our common stock and such lack of research coverage may adversely affect the market
price of our common stock.

We have never paid cash dividends on our capital stock, and we do not anticipate paying any dividends in the foreseeable future.

We  have  never  paid  cash  dividends  on  any  of  our  capital  stock  and  currently  intend  to  retain  our  future  earnings  to  fund  the  development  and  growth  of  our
business. As a result, capital appreciation, if any, of our common stock will be the sole source of gain for the foreseeable future.

Our  charter  documents  and  Delaware  law  could  discourage,  delay  or  prevent  a  change  of  control  of  our  company  or  change  in  our  management  that
stockholders consider favorable and cause our stock price to decline.

Certain provisions of our restated certificate of incorporation and restated bylaws and Delaware law could discourage, delay or prevent a change of control of our
company or change in our management that the stockholders of our company consider favorable. These provisions:

•

•
•

•
•
•

•
•
•

•

authorize the issuance of “blank check” preferred stock that our board of directors could issue to increase the number of outstanding shares and to discourage a
takeover attempt;
prohibit stockholder action by written consent, requiring all stockholder actions to be taken at a meeting of stockholders;
establish  advance  notice  procedures  for  nominating  candidates  to  our  board  of  directors  or  proposing  matters  that  can  be  acted  upon  by  stockholders  at
stockholder meetings;
limit the ability of our stockholders to call special meetings of stockholders;
prohibit stockholders from cumulating their votes for the election of directors;
permit newly created directorships resulting from an increase in the authorized number of directors or vacancies on our board of directors to be filled only by
majority vote of our remaining directors, even if less than a quorum is then in office;
provide that our board of directors is expressly authorized to make, alter or repeal our bylaws;
establish a classified board of directors so that not all members of our board are elected at one time;
provide that our directors may be removed only for “cause” and only with the approval of the holders of at least 66 2/3rds percent of our outstanding stock;
and
require super-majority voting to amend certain provisions in our certificate of incorporation and bylaws.

Section 203 of the Delaware General Corporation Law may also discourage, delay or prevent a change of control of our company.

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

The following discussion and analysis of our financial condition and results of operations should be read together with our consolidated financial statements and
related notes included in Item 8, “Financial Statements and Supplementary Data” included in this Annual Report on Form 10-K. This discussion and analysis
contains forward-looking statements that involve risks, uncertainties and assumptions, such as statements of our plans, objectives, expectations and intentions. The
cautionary statements made in this Annual Report on Form 10-K should be read as applying to all related forward-looking statements wherever they appear in this
Annual Report  on Form 10-K. Our actual results  may differ  materially  from those anticipated  in these  forward-looking statements as a result of many factors,
including but not limited to those set forth under Item 1A, “Risk factors” and elsewhere in this Annual Report on Form 10-K.

Business overview

We are a provider of secure, integrated, intelligent communication solutions, focused on empowering mobile workers in healthcare, hospitality, energy, and other
mission-critical mobile work environments, in the United States and internationally. Today, the significant majority of our business is generated from sales of our
solutions in the healthcare market to help our customers enhance patient safety and experience, improve staff resiliency and increase operational efficiency. As of
December 31, 2018, care teams at approximately 1,600 healthcare facilities worldwide have selected our solutions.

We primarily sell products, software maintenance and professional services directly to end users. Total revenue increased 8.2% to $179.6 million in 2018 from
$166.0 million in 2017 , and our 2017 revenue increased 25.7% from $132.0 million in 2016 . For the year ended December 31, 2018 , we recorded a net loss of
$9.7 million compared to a net loss of $10.9 million for the year ended December 31, 2017 .

Our  diverse  customer  base  ranges  from  large  hospital  systems  to  small  local  hospitals,  as  well  as  other  healthcare  facilities  and  customers  in  non-healthcare
markets. We do not rely on any one customer for a substantial portion of our revenue. While we have international customers in other English-speaking countries
such as Canada, the United Kingdom, Australia, New Zealand and parts of the Middle East, most of our customers are located in the United States. International
customers represented 10.2% and 10.2% of our revenue in 2018 and in 2017 , respectively. We believe certain international markets represent attractive growth
opportunities. We are exploring plans to expand our presence in other English-speaking markets and enter non-English speaking markets.

We outsource the manufacturing of our hardware products. Our outsourced manufacturing model allows us to scale our business without the significant capital
investment  and  on-going  expenses  required  to  establish  and  maintain  manufacturing  operations.  We  work  closely  with  our  contract  manufacturers,  including
Sercomm Corporation and SMTC Corporation, and key suppliers to manage the procurement, quality and cost of components. We seek to maintain an optimal
level of finished goods inventory to meet our forecast for sales and unanticipated shifts in sales volume and mix.

In the fourth quarter of 2016, we acquired all of the outstanding equity interest of Extension Healthcare for $52.5 million in cash. In addition, $2.5 million has been
set  aside  for  retention  bonuses  for  key  employees  of  which  $0.5  million  and  $1.0  million  was  paid  in  December  2016  and  October  2017,  respectively  and  the
remaining $.5 million due was paid in October 2018.

In  May  2014,  the  FASB together  with  the  International  Accounting  Standards  Board  issued  converged  guidance  for  revenue  recognition  that  will  replace  most
existing guidance, eliminate industry-specific guidance and provide a unified model for determining how and when revenue from contracts with customers should
be recognized. Under the new guidance, 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.

The new guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the
cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). 

We adopted the new guidance on January 1, 2018 using the full retrospective method, which requires us to present our historical financial information for fiscal
years 2017 and 2016 as if the new revenue guidance had been applied to all prior periods. 

The most significant impact of the standard relates to the timing of revenue recognition for software licenses sold with professional services where we did not have
vendor  specific  objective  evidence  (VSOE)  for  professional  services  under  current  guidance.      Under  the  new  standard,  the  requirement  to  have  VSOE  for
undelivered elements is eliminated and we will recognize revenue for software licenses upon transfer of control to our customers. Additionally, the new standard
requires the capitalization and amortization of costs related to obtaining a contract, such as sales commissions, which are currently recorded as an expense to sales
and marketing at the time they are incurred.  

34

Table of Contents

The adoption of the standard resulted in the recognition of additional revenue of $3.4 million and $4.3 million for the years ended December 31, 2017 and 2016,
respectively, an increase in gross profit of $3.4 million and $4.3 million for the years ended December 31, 2017 and 2016, respectively, an increase (decrease) in
sales  and  marketing  expense  of  $0.1  million  and $(1.5)  million  for  the  years  ended  December  31,  2017  and  2016,  respectively,  and  a  decrease  in  loss  from
operations of $3.3 million and $5.9 million for the years ended December 31, 2017 and 2016, respectively. In addition, the adoption of the standard resulted in a
decrease  in  total  net  deferred  revenue  of  $8.5  million  and  $5.3  million  as  of  December  31,  2017  and  2016,  respectively,  driven  by  the  upfront  recognition  of
software licenses sold with professional services for which we do not have VSOE, and an increase in total deferred commissions of $10.3 million and $10.4 million
as of December 31, 2017 and 2016, respectively, which will be recognized in sales and marketing expense in future periods. The adoption of the standard has not
had a significant impact to the provision for income taxes and has not had an impact on net cash from or used in operating, investing, or financing activities on our
consolidated  statements  of  cash  flows.  Refer  to  Note  2  in  the  Notes  to  Consolidated  Financial  Statements  for  the  impact  of  adoption  of  the  standard  on  the
Company's consolidated balance sheets and consolidated statements of operations.

Convertible Senior Notes

In May 2018, we issued $143.75 million aggregate principal amount of 1.50% Convertible Senior Notes due 2023, including $18.75 million aggregate principal
amount of such notes pursuant to the exercise in full of options granted to the initial purchasers, collectively the “Notes.” The total net proceeds from the offering,
after deducting initial purchase discounts and debt issuance costs, were approximately $138.9 million .

In  connection  with  the  pricing  of  the  Notes,  we  entered  into  privately  negotiated  capped  call  transactions  with  certain  counterparties,  the  “Capped  Calls.”  The
Capped Calls each have an initial strike price of approximately $32.25 per share, subject to certain adjustments, which correspond to the initial conversion price of
the  Notes.  The  Capped  Calls  have  initial  cap  prices  of  $38.94  per  share,  subject  to  certain  adjustments.  The  Capped  Calls  cover,  subject  to  anti-dilution
adjustments, approximately 4.5 million shares of our common stock. We used proceeds of $8.9 million to purchase the Capped Calls, which were recorded as a
reduction to additional paid-in capital. For further discussion on the Capped Calls, please refer to Note 8 in the Notes to Consolidated Financial Statements.

We expect to use the remaining net proceeds for general corporate purposes, which may include funding research and development, increasing working capital,
acquisitions or investments in complementary businesses, products or technologies and capital expenditures.

New Accounting Standards

We adopted Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606) (ASC 606), the new accounting standard related
to revenue recognition, effective January 1, 2018. Prior period information presented has been adjusted to reflect the adoption of this new standard. See Note 2 of
Notes to Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K for a summary of adjustments.

Components of operating results

Revenue.     We generate revenue from the sale of products and services. As discussed further in the section titled “Critical accounting policies and estimates—
Revenue recognition” below, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable
and collection is reasonably assured.

Revenue is comprised of the following:

•

Product.     Our solutions include both hardware and software. We refer to hardware revenue as device revenue, which includes revenue from sales of our
communication  badges  and  badge  accessories,  which  include  batteries,  battery  chargers,  lanyards,  clips  and  other  ancillary  badge  components  as  well  as
revenue  from  the  resale  of  TC51devices  and  related  accessories.  Software  revenue  is  derived  primarily  from  the  sale  of  perpetual  licenses  to  our  Vocera
Communication and Workflow System. We derive additional software revenue from the sale of term licenses and hosted software subscriptions, which can be
renewed on a subscription basis. Product revenue is generally recognized upon shipment of hardware and perpetual licenses and, in the case of term licenses or
subscription services, ratably over the applicable term.
Service.     We receive service revenue from sales of software maintenance, extended hardware warranties and professional services. Software maintenance is
typically  invoiced  annually  in advance,  recorded  as deferred  revenue,  and  recognized  as revenue  ratably  over  the  service  period.  Our professional  services
revenue is based on both time and materials, and fixed price contracts, and is recognized as the services are provided. Extended warranties are invoiced in
advance, recorded as deferred revenue, and recognized ratably over the extended warranty period.

Cost of revenue.     Cost of revenue is comprised of the following:

•

Cost of product.     Cost of product is comprised primarily of materials costs, software license costs, write-offs for excess and obsolete inventory, warranty,
and manufacturing overhead costs for test engineering, material requirements planning and our shipping and receiving functions. These overhead costs also
include facilities, equipment depreciation, amortization of developed technology and stock-based compensation expenses. We expect material costs to vary
with the product life cycle of our devices.
Cost  of  service.          Cost  of  service  is  comprised  primarily  of  employee  wages,  benefits  and  related  personnel  expenses  of  our  technical  support  team,  our
professional consulting personnel and our training teams. Cost of service also includes facility and information technology costs. We expect our cost of service
will increase as we continue to invest in support services to meet the needs of our customer base.

Operating expenses.     Operating expenses are comprised of the following:

•

•

•

Research and development.     Research and development expenses consist primarily of employee wages, benefits and related personnel expenses, hardware
materials, and consultant fees and expenses related to the design, development, testing and enhancements of our solutions. We intend to continue to invest in
improving the functionality of our solutions and the development of new solutions.
Sales and marketing.     Sales and marketing expenses consist primarily of employee wages, benefits and related personnel expenses, as well as trade shows,
marketing programs and collateral and public relations programs.
General and administrative.     General and administrative expenses consist primarily of employee wages, benefits and related personnel expenses, consulting,
accounting fees, legal fees and other general corporate expenses.

Interest income and other income (expense), net.

•

•

•

Interest income.     Interest income consists primarily of interest income earned on our cash, cash equivalent and short-term investment balances. Our interest
income  will  vary  each  reporting  period  depending  on  our  average  cash,  cash  equivalent  and  short-term  investment  balances  during  the  period  and  market
interest rates.
Interest expense. Interest expense consists of amortization of debt discount and debt issuance costs as well as the contractual interest incurred of the issuance
of the Convertible Senior Notes which are discussed in further detail in Note 8 to the consolidated financial statements.
Other income (expense), net.     Other income (expense), net consists primarily of foreign exchange gains and losses.

Provision for income taxes.     We are subject to income taxes in the countries where we sell our solutions. We anticipate that in the future as we expand our sale
of solutions to customers outside the United States, we will become subject to taxation based on the foreign statutory rates in the countries where these sales took
place and our effective tax rate could fluctuate accordingly. Currently, each of our international subsidiaries is operating under cost plus agreements where the U.S.
parent company reimburses the international subsidiary for its costs plus an arm's length profit.

Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the
financial  statement  and  tax  bases  of  assets  and  liabilities  using  enacted  tax  rates  in  effect  for  the  year  in  which  the  differences  are  expected  to  affect  taxable
income.  Valuation  allowances  have  been  established  to  reduce  deferred  tax  assets  to  the  amount  reasonably  expected  to  be  realized.  Changes  in  valuation
allowances are reflected as a component of provision for income taxes.

At December 31, 2018 , we held a $40.1 million valuation allowance against our deferred tax assets. We review on a quarterly basis our conclusions about the
appropriate amount of our deferred income tax asset valuation allowance.

Total revenue increased $13.6 million , or 8.2% , for the year ended December 31, 2018 compared to the year ended December 31, 2017. The increase in total
revenue was a result of increases in both product and services revenue.

Product  revenue  increased  $5.9  million  ,  or  6.4% ,  for  the  year  ended  December  31,  2018  compared  to  the  year  ended  December  31,  2017.  Device  revenue
decreased $1.6 million , or 2.6% , and software revenue increased $7.5 million , or 25.1% , for the year ended December 31, 2018, compared to the year ended
December 31, 2017. The decrease in device revenue was driven primarily by a decrease in unit sales of badges and related accessories to new customers making
initial purchases and existing customers expanding deployments within their facilities to departments and users. The increase in software revenue was mainly a
result of an increase in unit sales of licenses of our software platform.

Service revenue increased $7.8 million , or 10.5% , for the year ended December 31, 2018 compared to the year ended December 31, 2017. Software maintenance
and  support  revenue  increased  $9.9  million  ,  or  19.0% ,  and  professional  services  and  training  revenue  decreased  $2.1  million  ,  or  9.7% ,  for  the  year  ended
December 31, 2018 compared to the year ended December 31, 2017. The increase in software maintenance and support revenue was primarily a result of having a
larger customer base. The decrease in professional services and training revenue was due to a decrease of implementation services for our solutions.

Cost of product revenue increased $0.2 million , or 0.7% , for the year ended December 31, 2018 compared to the year ended December 31, 2017. The cost of
product revenue increased  primarily  due to an increase  of fixed overhead costs. Product gross margin as a percentage  of product revenue increased  in the year
ended December 31, 2018 compared to the year ended December 31, 2017 due to a larger mix of software revenue and higher absorption of fixed overhead costs.

Cost of service revenue increased $2.6 million , or 7.0% , for the year ended December 31, 2018 compared to the year ended December 31, 2017. The cost of
service  revenue  increased  primarily  due  to  an  increase  in  headcount.  Service  gross  margin  as  a  percentage  of  service  revenue  increased  for  the  year  ended
December 31, 2018 compared to the year ended December 31, 2017 primarily due to an increase in software maintenance and support revenue which typically
yields higher margins.

Research and development expense . Research and development expense increased $3.2 million , or 11.5% , for the year ended December 31, 2018 compared to
the year ended December 31, 2017. This increase was primarily due to a $2.0 million increase in compensation and benefits associated with increased headcount as
well as a $1.2 million increase in outside services primarily related to the development of our new Smartbadge announced in January 2019.

Interest income. Interest income increased $2.4 million for the year ended December 31, 2018 compared to the year ended December 31, 2017. This increase was
due to having higher cash balances as a result of the issuance of the Notes combined with a higher rate of return on our investments. For further discussion on the
Notes, please refer to Note 8 to the Consolidated Financial Statements.

Interest expense. For the year ended December 31, 2018, we had interest expense of $5.2 million resulting from the amortization of debt discount and debt issuance
costs and the contractual interest incurred on the issuance of the Notes.

Other expense, net. The change in other expense, net for the year ended December 31, 2018 compared to the year ended December 31, 2017 was primarily due to
foreign exchange fluctuations.

Provision  for income  taxes.  The $0.4 million benefit on $10.0 million of  loss  before  income  taxes  in  2018  represented  an  effective  tax  rate  of  3.5% . The tax
benefit for 2018 was due primarily to tax losses benefited against deferred tax liabilities as a result of teh enactment of the Tax Cuts and Jobs Act, partially offset
by  income  taxes  on  our  foreign  operations.  The  negative  effective  tax  rate  of  7.5% in  2017  was  due  primarily  to  the  re-measurement  of  the  net  deferred  tax
liabilities, resulting in a deferred tax benefit of $0.8 million upon the enactment of the Tax Cuts and Jobs Act as well as the impact of pre-tax losses in the U.S.
operations, partially offset by income taxes on our foreign operations.

Research and development expense . Research and development expense increased $9.4 million, or 51.6%, for the year ended December 31, 2017 compared to the
year  ended  December  31,  2016.  This  increase  was  primarily  due  to  a  $7.3  million  increase  in  compensation  and  benefits  associated  with  increased  headcount
resulting from the acquisition in October 2016.

Sales and marketing expense. Sales and marketing expense increased $8.8 million, or 17.2%, for the year ended December 31, 2017 compared to the year ended
December 31, 2016. This was primarily due to a $7.0 million increase in compensation and benefits associated with increased headcount. The sales and marketing
expense  increase  was  also  due  to  a  $0.8  million  increase  in  outside  services  and  a  $1.1  million  increase  in  amortization  of  intangibles  related  to  a  full  year  of

Interest income. Interest income decreased $0.1 million for the year ended December 31, 2017 compared to the year ended December 31, 2016 due to a decrease in
cash, cash equivalents and short-term investments partially offset by higher yields on interest bearing instruments.

Other expense, net. The change in other expense, net for the year ended December 31, 2017 compared to the year ended December 31, 2016 was primarily due to
foreign exchange fluctuations.

Provision for income taxes. The $0.8 million provision on $10.1 million of loss before income taxes in 2017 represented a negative effective tax rate of 7.5%. The
negative effective tax rate for 2017 was due primarily to the re-measurement of the net deferred tax liabilities, resulting in a deferred tax benefit of $0.7 million,
upon the enactment of the Tax Cuts and Jobs Act, as well as the impact of pre-tax losses in the U.S. operations, partially offset by income taxes on our foreign
operations. The negative effective tax rate of 4.9% in 2016 is due primarily to the impact of pre-tax losses in the U.S. operations, offset by income taxes from
foreign operations.

As of December 31, 2018 , we had cash and cash equivalents and short-term investments of $221.2 million .

In May 2018, we issued Convertible Senior notes with a 1.5% interest rate for an aggregate principal amount of $143.75 million. There are no required principal
payments prior to the maturity of the Notes. For additional information, see Note 8 of Notes to Consolidated Financial Statements included in Part II, Item 8 of this
Annual Report on Form 10-K.

During 2018 , 2017 and 2016 , our purchases of property and equipment were $4.9 million, $2.8 million and $4.7 million, respectively. The expenditures in 2018
primarily  related  to  leasehold  improvements  and  computer  equipment.  The  expenditures  in  2017  primarily  relate  to  leasehold  improvements  and  computer
equipment. The expenditures in 2016 primarily relate to leasehold improvements related to the renovation of our corporate offices.

We believe that our existing sources of liquidity will satisfy our anticipated working capital and capital requirements for at least the next twelve months. Our future
liquidity and capital requirements will depend upon numerous factors, including our rate of growth, the rate at which we add personnel to generate and support
future growth, and potential future acquisitions.

In  the  future,  we  may  seek  to  sell  additional  equity  securities  or  borrow  funds.  The  sale  of  additional  equity  or  convertible  securities  may  result  in  additional
dilution to our stockholders.  If  we raise additional  funds through the issuance of debt securities  or other borrowings, these  securities  or borrowings could have
rights senior to those of our common stock and could contain covenants that could restrict our operations. Any required additional capital may not be available on
reasonable terms, if at all.

Operating activities

Cash provided by operating activities was $14.3 million in 2018, due in part to non-cash items such as stock-based compensation of $21.0 million, amortization of
debt  discount  and  issuance  costs  of  $3.9  million  and  depreciation  and  amortization  of  $7.7  million  for  property  and  equipment  and  acquired  intangible  assets,
partially offset by the 2018 net loss of $9.7 million . With respect to changes in assets and liabilities, cash was provided through an increase of $1.5 million in
accounts payable and an increase of $3.5 million in deferred revenue. These factors were partially offset by certain cash outflows, including an increase in accounts
receivable  of $5.0 million,  an increase  in other  receivables  of $2.8 million,  an increase  in inventory  of $1.9 million,  an increase  in prepaid  expenses  and other
assets of $0.6 million, a decrease of $4.1 million in accrued payroll and other liabilities.

Cash provided by operating activities was $7.7 million in 2017, due in part to non-cash items such as stock-based compensation of $18.2 million and depreciation
and amortization of $7.6 million for property and equipment and acquired intangible assets, partially offset by the 2017 net loss of $10.8 million. With respect to
changes in assets and liabilities, cash was provided through a decrease of $1.4 million in inventory and a $5.4 million increase in deferred revenue. These factors
were partially offset by certain cash outflows, including an increase in accounts receivable of $11.0 million, which is attributable to current period's billings
exceeding collection on prior periods' invoices, an increase in prepaid expenses and other assets of $0.9 million, a decrease of $0.6 million in accounts payable and
a decrease of $1.1 million in accrued payroll and other liabilities.

Cash provided by operating activities was $11.3 million in 2016, due in part to non-cash items such as stock-based compensation of $12.0 million, $2.6 million in
non-cash compensation expense and depreciation and amortization of $3.8 million for property and equipment and acquired intangible assets, partially offset by the
2016 net loss of $11.4 million. With respect to changes in assets and liabilities, cash was provided through a decrease of $0.1 million in other receivables, a $0.2
million increase in accounts payable, a $2.4 million increase in accrued liabilities and an $6.9 million increase in deferred revenue. These factors were partially
offset by certain cash outflows, including an increase in accounts receivable of $0.3 million, which is attributable to current period's billings exceeding collection
on prior  periods'  invoices,  an increase  in inventory  of $2.0 million,  an increase  in deferred  commissions  of $1.5 million  and a $0.8 million  increase  in prepaid
expenses and other assets.

Investing activities

Cash  used  in  investing  activities  was  $139.5  million  in  2018,  which  was  primarily  attributable  to  $72.2  million  in  short-term  investment  maturities,  offset  by
$206.8 million in purchases  of short-term  investments.  An additional  $4.9 million of  cash  was  used  for  the  purchase  of  property  and  equipment  and  leasehold
improvements.

Cash provided by investing activities was $16.4 million in 2017, which was primarily attributable to $53.8 million in short-term investment maturities offset by
$67.4  million  in  purchases  of  short-term  investments.  An  additional  $2.8  million  of  cash  was  used  for  the  purchase  of  property  and  equipment  and  leasehold
improvements.

Cash provided by investing activities was $0.1 million in 2016, which was primarily attributable to $111.8 million in short-term investment maturities and $32.1
million in sales of short-term investments, offset by $86.6 million in purchases of short-term investments and $52.5 million used to complete the acquisition in
October 2016. An additional $4.7 million of cash was used for the purchase of property and equipment and leasehold improvements.

Financing activities    

Cash provided by financing activities was $130.8 million in 2018, primarily attributable to $7.3 million of proceeds from stock option exercises, $3.3 million of
proceeds from issuance of common stock from the employee stock purchase plan and $0.3 million of cash from lease-related performance obligations. These items
were partially offset by a $10.1 million decrease for employee taxes paid on net share settlement on the vesting of restricted stock awards.

Cash  provided  by  financing  activities  was  $2.4  million  in  2017,  primarily  attributable  to  $7.9  million  of  proceeds  from  stock  option  exercises,  $2.8  million  of
proceeds from issuance of common stock from the employee stock purchase plan and $0.7 million of cash from lease-related performance obligations. These items
were partially offset by a $9.0 million decrease for employee taxes paid on net share settlement on the vesting of restricted stock awards.

Cash  provided  by  financing  activities  was  $3.1  million  in  2016,  primarily  attributable  to  $2.5  million  of  proceeds  from  stock  option  exercises,  $1.7  million  of
proceeds from issuance of common stock from the employee stock purchase plan and $1.6 million of cash from lease-related performance obligations. These items
were partially offset by a $2.7 million decrease for employee taxes paid on net share settlement on the vesting of restricted stock awards.

As of December 31, 2018 , we had $0.5 million of net deferred tax liabilities and $0.3 million from uncertain tax positions, both recorded within other long-term
liabilities. The timing and amounts of any payments that could result from the net deferred tax liabilities and unrecognized tax benefits will depend upon a number
of factors. Accordingly, the timing and amounts of any eventual payment cannot be estimated for inclusion in the table above. We do not expect a significant tax
payment related to these obligations to occur within the next 12 months. Such tax contingencies are separately disclosed and discussed in Note 12 of the notes to
our consolidated financial statements.

Off-balance sheet arrangements

During 2018 , we did not have any relationships with unconsolidated organizations or financial partnerships, such as structured finance or special purpose entities
that would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

Critical accounting policies and estimates

The  preparation  of  our  consolidated  financial  statements  requires  us  to  make  estimates  and  assumptions  that  affect  the  amounts  reported  in  the  consolidated
financial  statements  and  accompanying  notes.  We  evaluate  our  estimates  on  an  ongoing  basis,  including  those  related  to  product  warranties,  goodwill  and
intangible assets, revenue recognition, stock-based compensation, accounting for business combinations and the provision for income taxes. We base our estimates
and judgments on our historical experience, knowledge of factors affecting our business and our belief as to what could occur in the future considering available
information and assumptions that we believe to be reasonable under the circumstances.

The accounting estimates we use in the preparation of our consolidated financial statements will change as events occur, more experience is acquired, additional
information  is  obtained  and  our  operating  environment  changes.  Changes  in  estimates  are  made  when  circumstances  warrant.  Such  changes  in  estimates  and
refinements in estimation methodologies are reflected in our reported results of operations and, if material, the effects of changes in estimates are disclosed in the
notes to our consolidated financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty and actual results
could differ materially from the amounts reported based on these estimates.

While our significant accounting policies are more fully described in Note 1 of the “Notes to our consolidated financial statements” included in Item 8, “Financial
Statements and Supplementary Data,” we believe the following reflects our critical accounting policies and our more significant judgments and estimates used in
the preparation of our financial statements.

Revenue Recognition

Some of our contracts with customers contain multiple performance obligations. Determining whether products and services are considered distinct performance
obligations that should be accounted for separately versus together may require significant judgment. For these contracts, we account for individual performance
obligations separately  if they are distinct.  The transaction  price is allocated to the separate performance  obligations on a relative  standalone selling price (SSP)
basis. For deliverables that we routinely sell separately, such as support and maintenance on our core offerings, we determine SSP by evaluating the standalone
sales  over  the  trailing  12  months.  For  those  that  are  not  sold  routinely,  we  determine  SSP  based  on  our  overall  pricing  trends  and  objectives,  taking  into
consideration market conditions and other factors, including the value of our contracts, the products sold and geographic locations.

If  the  contract  contains  a  single  performance  obligation,  the  entire  transaction  price  is  allocated  to  the  single  performance  obligation.  Contracts  that  contain
multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative SSP. We determine SSP based on
the price at which the performance obligation is sold separately. If the SSP is not observable through past transactions, we estimate the SSP, taking into account
available information such as market conditions and internally approved pricing guidelines related to the performance obligations.

The  new  standard  related  to  revenue  recognition,  ASC  606,  had  a  material  impact  on  our  consolidated  financial  statements.  Refer  to  Note  2  of  Notes  to
Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K for further discussion.

Standard product warranties

We  provide  for  the  estimated  costs  of  product  warranties  at  the  time  the  related  revenue  is  recognized.  Costs  are  estimated  based  on  historical  and  projected
product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific product warranty includes parts and
labor over a period generally ranging from one to three years. We provide no warranty for software. We regularly assess our estimates to evaluate the adequacy of
the recorded warranty liabilities and adjust the amounts as necessary. The total warranty expense under our standard warranty in 2018 was $0.1 million, compared
to $0.1 million in 2017 and $0.2 million in 2016. The key drivers to the warranty reserve calculation are the installed base of products under standard warranty, the
estimated return rate of the installed base of products under standard warranty, and the availability of refurbished units to fulfill expected warranty claims.

Stock-based compensation

Restricted Stock Units

We record all stock-based awards, which consist restricted stock units, at fair value as of the grant date and recognize the expense over the requisite service period
(generally over the vesting period of the award). The restricted stock units generally vest one third on the first anniversary of the grant, one third on the second
anniversary of the grant and one third upon the third anniversary of the grant. The grant date fair value of the RSUs is the closing market price on the date of grant;
this amount is charged to expense ratably over the requisite service period.

Goodwill and intangible assets

We  allocate  the  purchase  price  of  any  acquisitions  to  tangible  assets  and  liabilities  and  identifiable  intangible  assets  acquired.  Any  residual  purchase  price  is
recorded as goodwill. The allocation of the purchase price requires management to make significant

44

Table of Contents

estimates  in  determining  the  fair  values  of  assets  acquired  and  liabilities  assumed,  especially  with  respect  to  intangible  assets.  These  estimates  are  based  on
information obtained from management of the acquired companies and historical experience. These estimates can include, but are not limited to, the cash flows that
an asset is expected to generate in the future, and the cost savings expected to be derived from acquiring an asset. These estimates are inherently uncertain and
unpredictable, and if different estimates were used the purchase price for the acquisition could be allocated to the acquired assets and liabilities differently from the
allocation that we have made. In addition, unanticipated events and circumstances may occur which affect the accuracy or validity of such estimates, and if such
events occur we may be required to record a charge against the value ascribed to an acquired asset or an increase in the amounts recorded for assumed liabilities.

Goodwill

Goodwill is tested for impairment at the reporting unit level at least annually, or more often if events or changes in circumstances indicate the carrying value may
not be recoverable. Our annual assessment date is October 1st and the results of our assessment performed as of October 1st indicated no impairment had been
incurred. No impairment was recorded in 2018 , 2017 or 2016 . As of December 31, 2018 , no changes in circumstances indicate that goodwill carrying values may
not be recoverable. Application of the goodwill impairment test requires judgment. Circumstances that could affect the valuation of goodwill include, among other
things, a significant change in our business climate and the buying habits of our customers along with changes in the costs to provide our products and services.

Intangible assets

Intangible  assets  are  amortized  over  their  estimated  useful  lives.  Upon  completion  of  development,  acquired  in-process  research  and  development  assets  are
generally considered amortizable, finite-lived assets and are amortized over their estimated useful lives.

Finite-lived  intangible  assets  consist  of  customer  relationships,  developed  technology,  trademarks,  backlog  and  non-compete  agreements.  We  evaluate  our
intangible  assets  for  impairment  at  the  asset  group  level,  which  means  the  intangibles  grouped  with  other  assets  and  liabilities  at  the  lowest  level  for  which
identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Management has concluded that our asset groups align with our
reporting units. The intangible assets are allocated to the Product and Services asset groups, given that the Product and Services asset groups are the lowest level
for which discrete cash flow information are identifiable, independent from other assets. We assess the recoverability of these assets whenever adverse events or
changes  in  circumstances  or  business  climate  indicate  that  expected  undiscounted  future  cash  flows  related  to  such  intangible  assets  may  not  be  sufficient  to
support the net book value of such assets. An impairment is recognized in the period of identification to the extent the carrying amount of an asset exceeds the fair
value of such asset. No impairment of intangible assets was recorded in 2018 , 2017 or 2016 .

Significant  judgments  required  in  assessing  the  impairment  of  goodwill  and  intangible  assets  include  the  identification  of  reporting  units,  identifying  whether
events or changes in circumstances require an impairment assessment, estimating future cash flows, determining appropriate discount and growth rates and other
assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value as to whether an impairment exists and, if so, the
amount of that impairment.

Income taxes    

We use the asset and liability method of accounting for income taxes. Under this method, we record deferred income taxes based on temporary differences between
the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that we expect will be in effect when we recover those assets or
settle those liabilities, as the case may be, to measure those taxes. In cases where the expiration date of tax carryforwards or the projected operating results indicate
that  realization  is  not  likely,  we  provide  for  a  valuation  allowance.  Valuation  allowances  are  established  when  necessary  to  reduce  deferred  tax  assets  to  the
amounts expected to be realized.

We have deferred tax assets, resulting from deductible temporary differences that may reduce taxable income in future periods. A valuation allowance is required
when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In assessing the need for a valuation allowance, we estimate future
taxable  income,  considering  the  feasibility  of  ongoing  tax-planning  strategies  and  the  realizability  of  tax  loss  carryforwards.  Valuation  allowances  related  to
deferred tax assets can be impacted by changes in tax laws, changes in statutory tax rates and future taxable income levels. If we were to determine that we would
be  able  to  realize  our  deferred  tax  assets  in  the  future  in  excess  of  the  net  carrying  amounts,  we  would  decrease  the  recorded  valuation  allowance  through  an
increase  to  income  in  the  period  in  which  that  determination  is  made.  Due  to  the  amount  of  net  operating  losses  available  for  income  tax  purposes  through
December 31, 2018 , we had a full valuation allowance against our deferred tax assets. We continue to evaluate the realizability of our U.S. and Canadian deferred
tax assets. If our financial results improve, we will reassess the need for a full valuation allowance each quarter and, if we determine that it is more likely than not
the deferred tax assets will be realized, we will adjust the valuation allowance.

At December 31, 2018 , we had a valuation allowance against net deferred tax assets of $40.1 million . We review on a quarterly basis our conclusions about the
appropriate amount of our deferred tax asset valuation allowance. There is inherent uncertainty

45

Table of Contents

in evaluating the sustainability of the income tax positions we take on our tax returns. We assess our income tax positions and record tax benefits for all years
subject to examination based upon our management’s evaluation of the facts, circumstances and information available at the reporting date. For those tax positions
where it is more likely than not that a tax benefit will be sustained, we have recorded the highest amount of tax benefit with a greater than 50% likelihood of being
realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more
likely than not that a tax benefit will be realizable, no tax benefit has been recognized in our financial statements.

We  include  interest  and  penalties  with  income  taxes  on  the  accompanying  statement  of  operations.  Our  tax  years  after  2011  are  subject  to  tax  authority
examinations. Additionally, our net operating losses and research credits are subject to tax authority adjustment.

Recently issued accounting guidance

See “Note 1. The Company and Summary of Significant Accounting Policies” of the Notes to Consolidated Financial Statements in “Item 8. Financial Statements
and Supplementary Data” for a full description of recent accounting pronouncements including the respective expected dates of adoption and estimated effects, if
any on our consolidated financial statements.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The primary objective of our investment activities is to preserve principal while maximizing yields without significantly increasing risk. To achieve this objective,
historically we have invested in money market funds. With the proceeds from our two public offerings in 2012 and our Notes offering in 2018, we have invested in
a broader portfolio of high credit quality short-term securities. To minimize the exposure due to an adverse shift in interest rates, we maintain an average portfolio
duration of one year or less.

Our primary exposure to market risk is interest income and expense sensitivity, which is affected by changes in the general level of the interest rates in the United
States. However, because of the short-term nature of our interest-bearing securities, a 10% change in market interest rates would not be expected to have a material
impact on our consolidated financial condition or results of operations.

Historically our operations have consisted of research and development and sales activities in the United States. As a result, our financial results have not been
materially affected by factors such as changes in foreign currency exchange rates or economic conditions in foreign markets. We are developing plans to expand
our  international  presence.  Accordingly,  we  expect  that  our  exposure  to  changes  in  foreign  currency  exchange  rates  and  economic  conditions  may  increase  in
future periods.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Vocera Communications, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Vocera Communications Inc. and subsidiaries (the "Company") as of December 31, 2018 and
2017, the related consolidated statements of operations, comprehensive loss, stockholders' equity, and cash flows, for each of the three years in the period ended
December 31, 2018, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all
material respects, the financial position of the Company as of December 31, 2018 and 2017, and the results of its operations and its cash flows for each of the three
years in the period ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal
control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee
of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2019, expressed an unqualified opinion on the Company's internal
control over financial reporting.

Change in Accounting Principle

As discussed in Note 2 to the financial statements, the Company has changed its method of accounting for revenue from contracts with customer in the fiscal year
ended December 2018 due to adoption of Accounting Standard Update 2014-09, Revenue from Contracts with Customers (ASC 606).

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements
based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance
with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to
assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such
procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the
accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe
that our audits provide a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the shareholders and the Board of Directors of Vocera Communications, Inc.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Vocera Communications, Inc. and subsidiaries (the “Company”) as of December 31, 2018, based
on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission
(COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on
criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated financial
statements as of and for the year ended December 31, 2018, of the Company and our report dated February 27, 2019, expressed an unqualified opinion on those
financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal
control over financial reporting, included in the accompanying Management’s Report on Internal Control Over Financial Reporting . Our responsibility is to
express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and
are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the
Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance
about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal
control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control
based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable
basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial
reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the
transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of

The Company and Summary of Significant Accounting Policies

Notes to Consolidated Financial Statements

Background

Vocera Communications, Inc. and its subsidiaries (collectively, the Company) is a provider of secure, integrated, intelligent communication and clinical workflow
solutions, focused on empowering mobile workers in healthcare, hospitality, energy, and other mission-critical mobile work environments, in the United States and
internationally. The significant majority of the Company's business is generated from sales of its solutions in the healthcare market to help its customers improve
quality of care, patient and staff experience and increase operational efficiency.

The Vocera Communication and Workflow System is comprised of a unique software platform that connects communication devices, including our hands-free,
wearable, voice-controlled communication badges, and third-party mobile devices that use our software applications to our enterprise-class software platform. The
system transforms the way mobile workers communicate by enabling them to instantly connect via voice or secure text messaging. With a portfolio of over 120
third-party clinical integrations, our system also enables the intelligent delivery of alerts and alarms to a variety of mobile devices, providing real time situation
awareness  to  care  providers.  The  Company's  unique  hands-free  voice  capability  allows  mobile  workers  to  connect  with  the  right  person  simply  by  saying  or
selecting the name, function or group name of the person they want to reach, often while remaining at the point-of-care. The Company's system responds to over
100 spoken commands.

The Company was incorporated in Delaware on February 16, 2000. The Company formed wholly-owned subsidiaries Vocera Communications UK Ltd and Vocera
Communications Australia Pty Ltd. in 2005, Vocera Canada, Ltd. in 2010, Vocera Communications India Private Ltd. in 2013, Vocera Communications Middle
East FZ LLC in 2014 and acquired Extension, LLC in 2016.

Since its inception, the Company has incurred significant losses and, as of December 31, 2018 , had an accumulated deficit of $132.3 million . The Company has
funded its operations primarily with customer payments for its products and services, proceeds from the issuance of common stock in connection with its initial
public offering (IPO) and follow-on offering and proceeds from the issuance of convertible senior notes. As of December 31, 2018 , the Company had cash, cash
equivalents and short-term investments of $221.2 million .

The Company believes that its existing sources of liquidity will satisfy its working capital and capital requirements for at least the next twelve months.

Basis of presentation

The consolidated financial statements include the accounts of Vocera Communications, Inc. and its wholly owned subsidiaries. All inter-company transactions and
balances have been eliminated in consolidation. The accompanying notes are prepared in accordance with accounting principles generally accepted in the United
States (GAAP).

Effective January 1, 2018, we adopted Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (ASC 606), as discussed in detail in
Note 2. All amounts and disclosures set forth in this Annual Report on Form 10-K have been updated to comply with ASC 606, as indicated by the "as adjusted"
note. Certain prior period amounts have been adjusted as a result of our adoption of ASC 606. Refer to "Recently Adopted Accounting Pronouncements" below for
more information.

Use of estimates and reclassifications

The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of
assets  and  liabilities  and  disclosure  of  contingent  assets  and  liabilities  at  the  date  of  the  financial  statements  and  the  reported  amounts  of  revenue  and  expense
during  the  reporting  periods.  The  estimates  include,  but  are  not  limited  to,  revenue  recognition,  warranty  reserves,  inventory  reserves,  goodwill  and  intangible
assets, stock-based compensation expense, provisions for income taxes and contingencies. Actual results could differ from these estimates, and such differences
could be material to the Company’s financial position and results of operations.

Cash, cash equivalents and short-term investments

The  Company’s  cash  equivalents  and  short-term  investments  consist  of  money  market  funds,  commercial  paper,  U.S.  government  agency  notes,  U.S.  Treasury
notes, municipal debt and corporate debt. These investments are classified as available-for-sale securities and are carried at fair value with the unrealized gains and
losses reported as a component of stockholders’ equity. Management determines the appropriate classification of its investments at the time of purchase and re-
evaluates the available-for-sale designations as of each balance sheet date. Investments with an original purchase maturity of three months or less are classified as
cash equivalents, all those with longer maturities are classified as short-term investments, which are available-for-sale.

Allowance for doubtful accounts

The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the Company’s receivables portfolio determined on the
basis  of  historical  experience,  specific  allowances  for  known  troubled  accounts  and  other  currently  available  evidence.  The  Company  has  not  experienced
significant credit losses from its accounts receivable. The Company performs a regular review of its customers’ payment histories and associated credit risks as it
does not require collateral from its customers.

The following table presents the changes in the allowance for doubtful accounts:

Inventories are valued at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (net realizable value or replacement
cost).  The  Company  assesses  the  valuation  of  inventory  and  periodically  writes  down  the  value  for  estimated  excess  and  obsolete  inventory  based  upon
assumptions about future demand and market conditions.

Concentration of credit risk and other risks and uncertainties

Financial  instruments  that  subject  the  Company  to  concentration  of  credit  risk  consist  primarily  of  cash,  cash  equivalents  and  short-term  investments.  The
Company’s cash and cash equivalents are primarily deposited with high quality financial institutions and in money market funds. Deposits at these institutions and
funds may, at times, exceed federally insured limits. Management believes that these financial institutions and funds are financially sound and, accordingly, that
minimal credit risk exists. The Company has not experienced any losses on its deposits of cash and cash equivalents. Marketable securities are stated at fair value,
and accounted for as available-for-sale within short-term investments. The counterparties to the agreements relating to the Company’s investment securities consist
of major corporations, financial institutions and government agencies of high credit standing.

The primary hardware components of the Company’s products is currently manufactured by third-party contractors in Mexico and Taiwan. A significant disruption
in the operations of these contractors may impact the production of the Company’s products for a substantial period of time, which could harm the Company’s
business, financial condition and results of operations.

Concentration  of  credit  risk  with  respect  to  trade  accounts  receivable  is  considered  to  be  limited  due  to  the  diversity  of  the  Company’s  customer  base  and
geographic sales areas. At December 31, 2018 and 2017 , no customer accounted for 10% or more of accounts receivable. At December 31, 2018 and 2017, one
reseller represented 26.4% and 26.3% , respectively of accounts receivable. For the years ended December 31, 2018 , 2017 and 2016 , no customer represented
10% or more of revenue.

Property and equipment

Property and equipment  are stated  at cost and depreciated  on a straight-line  basis over the estimated  useful economic  lives of the assets. Assets generally  have
useful economic lives of three years except for leasehold improvements, which are amortized using the straight-line method over the shorter of the remaining lease
term or the estimated useful life of the related assets. Purchased or developed software also generally has a three year useful economic life, except for major ERP
implementations, for which the Company assumes a five year useful economic life. Upon retirement or sale, the cost and related accumulated depreciation and
amortization  are  removed  from  the  consolidated  balance  sheet  and  the  resulting  gain  or  loss  is  reflected  in  operations.  Maintenance  and  repairs  which  are  not
considered improvements and do not extend the useful life of the assets are charged to operations as incurred.

The Company periodically reviews property and equipment for impairment whenever events or changes in circumstances indicate that the carrying amount of an
asset is impaired or the estimated useful lives are no longer appropriate. Fair value is estimated based on discounted future cash flows. If indicators of impairment
exist and the undiscounted projected cash flows associated with such assets are less than the carrying amount of the asset, an impairment loss is recorded to write
the asset down to its estimated fair values. To date, the Company has not recorded any impairment charges.

Internal-use software development costs 

56

 
   
 
 
 
 
 
 
 
Table of Contents

For internal-use software, the Company capitalizes certain internal and external costs incurred in its acquisition and creation. Capitalized internal-use software is
included  in  property  and  equipment  when  development  is  complete  and  is  amortized  on  a  straight-line  basis  over  the  estimated  useful  life  of  the  related  asset,
generally three years, except that five years is assumed for major ERP implementations. Based on the authoritative guidance, costs incurred either before or after
the  period  satisfying  the  capitalization  criteria,  together  with  costs  incurred  for  training  and  maintenance,  are  expensed  as  incurred.  For  the  years  ended
December 31, 2018 , 2017 and 2016 , the Company capitalized costs of $0.7 million , $0.3 million and zero , respectively.

Goodwill and intangible assets

The Company allocates the purchase price of any acquisitions to tangible assets and liabilities and identifiable intangible assets acquired. Any residual purchase
price is recorded as goodwill.

Goodwill

Goodwill is tested for impairment at the reporting unit level at least annually, or more often if events or changes in circumstances indicate the carrying value may
not be recoverable. The Company has identified two operating segments (Product and Service) which management also considers to be reporting units. In testing
for goodwill impairment, the Company may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of a reporting
unit is less than its carrying value. If such qualitative assessment indicates that goodwill impairment is more likely than not, the Company performs a two-step
impairment  test.  The  Company  performed  its  goodwill  impairment  assessment  on  October  1,  2018  using  a  qualitative  assessment  and  determined  that  no
impairment existed as of the date of the impairment test because the fair value of each reporting unit exceeded its carrying value. As of December 31, 2018 , no
changes in circumstances indicate that goodwill carrying values may not be recoverable.

Intangible assets

Intangible  assets  are  amortized  over  their  estimated  useful  lives.  Upon  completion  of  development,  acquired  in-process  research  and  development  assets  are
generally  considered  amortizable,  finite-lived  assets  and  are  amortized  over  their  estimated  useful  lives.  Finite-lived  intangible  assets  consist  of  customer
relationships, developed technology, trademarks, backlog and non-compete agreements. The Company evaluates intangible assets for impairment by assessing the
recoverability  of  these  assets  whenever  adverse  events  or  changes  in  circumstances  or  business  climate  indicate  that  expected  undiscounted  future  cash  flows
related to such intangible assets may not be sufficient to support the net book value of such assets. An impairment is recognized in the period of identification to
the extent the carrying amount of an asset exceeds the fair value of such asset. No impairment of intangible assets was recorded in the years ended December 31,
2018 , 2017 or 2016 .

Revenue recognition

Effective January 1, 2018, we adopted ASC 606 using the full retrospective method. Refer to Note 2 for a detailed discussion of accounting policies related to
revenue recognition, including deferred revenue and commissions.

Revenue from sales-type leases

A portion of the Company's sales are made through multi-year lease agreements with customers. When these arrangements are considered sales-type leases, upon
delivery of leased products to customers, the Company recognizes revenue for such products in an amount equal to the net present value of the minimum lease
payments.  Unearned  income  is  recognized  as  part  of  product  revenue  under  the  effective  interest  method.  The  Company  recognizes  revenue  related  to  certain
executory costs, including maintenance and extended warranty, ratably over the term of the underlying arrangements. The Company recognizes revenue related to
battery refresh executory costs when such executory costs are incurred.

Proceeds from transfers of sales-type leases to third-party financial companies are allocated between the net investment in sales-type leases and the executory cost
component for remaining service obligations based on relative present value. The difference between the amount of proceeds allocated to the net investment in
lease and the carrying value of the net investment in lease is included in product revenue. Proceeds allocated to the executory cost component are accounted for as
financing liabilities.

For the year ended December 31, 2018 , the Company transferred $0.4 million  of lease receivables, recording an immaterial net loss and   $0.3 million  of new
financing liabilities for future performance of executory service obligations. For the year ended December 31, 2017 , the Company transferred $0.9 million of lease
receivables, recording an immaterial net loss and  $0.7 million  of new financing liabilities for future performance of executory service obligations.

For lease receivables retained as of December 31, 2018 and 2017 , the Company recorded  $0.7 million and $1.3 million , respectively, of net investment in sales-
type leases, equivalent to the minimum lease payments for the delivered product.

Shipping and handling costs

57

Table of Contents

Shipping and handling costs charged to customers are included in revenue and the associated expense is recorded in cost of revenue in the consolidated statements
of operations for all periods presented.

Research and development expenditures

Research and development  costs are charged  to operations  as incurred. Software development costs incurred  for external  products prior to the establishment  of
technological feasibility are included in research and development and are expensed as incurred. After technological feasibility is established, material software
development costs up to general availability of the software will be capitalized and amortized on a straight-line basis over the estimated product life, or based on
the ratio of current revenues to total projected product revenue, whichever is greater. To date, the time between the establishment of technological feasibility and
general  availability  has  been  very  short  and  therefore  no  significant  costs  have  been  incurred.  Accordingly,  the  Company  has  not  capitalized  any  software
development costs related to research and development expenditures.

Advertising costs

Advertising costs are included in sales and marketing expense and are expensed as incurred. Advertising costs for the years ended December 31, 2018 , 2017 and
2016 were immaterial.

Product warranties

The  Company  offers  warranties  on  certain  products  and  records  a  liability  for  the  estimated  future  costs  associated  with  warranty  claims,  which  is  based  upon
historical experience and the Company’s estimate of the level of future costs. The Company provides for the estimated costs of hardware warranties at the time the
related revenue is recognized. Costs are estimated based on historical and projected product failure rates, historical and projected repair costs, and knowledge of
specific product failures (if any). The specific hardware warranty includes parts and labor over a period generally ranging from one to three years. The Company
provides  no  warranty  for  software.  The  Company  regularly  re-evaluates  its  estimates  to  assess  the  adequacy  of  the  recorded  warranty  liabilities  and  adjust  the
amounts as necessary. Warranty costs are reflected in the consolidated statement of operations as cost of revenue.

Stock-based compensation

Stock-based compensation is measured at grant date based on the fair value of the award using the grant date closing stock price and is expensed on a straight-line
basis over the requisite service period.

Income taxes

The  Company  uses  the  asset  and  liability  method  of  accounting  for  income  taxes.  Under  this  method,  the  Company  records  deferred  income  taxes  based  on
temporary differences between the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that the Company expects will be in
effect when they recover those assets or settle those liabilities, as the case may be, to measure those taxes. In cases where the expiration date of tax carryforwards
or the projected operating results indicate that realization is not likely, the Company provides for a valuation allowance. Valuation allowances are established when
necessary to reduce deferred tax assets to the amounts expected to be realized.

The Company has deferred tax assets, resulting from net operating losses, research and development credits and temporary differences that may reduce taxable
income  in future  periods.  A valuation  allowance  is  required  when  it  is more  likely  than  not  that  all  or a  portion  of a  deferred  tax  asset  will not  be realized.  In
assessing the need for a valuation allowance, the Company estimates future taxable income, considering the feasibility of ongoing tax-planning strategies and the
realizability of tax loss carryforwards. Valuation allowances related to deferred tax assets can be impacted by changes in tax laws, changes in statutory tax rates
and future taxable income levels. If the Company were to determine that it would be able to realize its deferred tax assets in the future in excess of the net carrying
amounts, it would decrease the recorded valuation allowance through an increase to income in the period in which that determination is made. Due to the history of
losses the Company has generated in the past, the Company believes that it is not more likely than not that all of the deferred tax assets in the U.S. and Canada can
be realized as of December 31, 2018 and 2017, respectively. Accordingly, the Company has recorded a full valuation allowance on its deferred tax assets for these
years.

At December 31, 2018 , the Company had a valuation allowance against net deferred tax assets of $40.1 million .

There is inherent uncertainty in evaluating the sustainability of the income tax positions the Company takes on its tax returns. The Company assesses its income tax
positions and records tax benefits for all years subject to examination based upon management’s evaluation of the facts, circumstances and information available at
the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, the Company has recorded the highest amount of tax
benefit with a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information.
For  those  income  tax  positions  where  it  is  not  more  likely  than  not  that  a  tax  benefit  will  be  realizable,  no  tax  benefit  has  been  recognized  in  the  financial
statements.

Table of Contents

The  Company  includes  interest  and  penalties  with  income  taxes  in  the  accompanying  statement  of  operations.  All  of  the  Company’s  net  operating  losses  and
research credit carryforwards are subject to adjustment by tax authorities and all years after 2011 are still subject to tax authority examinations. The Company is
currently not subject to any income tax audit examinations by tax authorities in any jurisdictions including U.S. federal, state and local or foreign countries.

Foreign currency translation

The functional currency of the Company’s foreign subsidiaries is the U.S. dollar.  Accordingly, monetary assets and liabilities in non-functional currency of these
subsidiaries are remeasured using exchange rates in effect at the end of the period. Revenues and costs in local currency are remeasured using average exchange
rates  for  the  period,  except  for  costs  related  to  those  consolidated  balance  sheet  items  that  are  remeasured  using  historical  exchange  rates.  The  resulting
remeasurement gains and losses are included in the Company’s consolidated statements of operations. Translation gains and losses have not been significant to
date.

Segments

Operating  segments  are  components  of  an  enterprise  for  which  separate  financial  information  is  available  and  is  evaluated  regularly  by  the  Company’s  chief
operating  decision  maker  in  deciding  how  to  allocate  resources  and  in  assessing  performance.  The  Company’s  chief  operating  decision  maker  is  the  Chief
Executive Officer. The Company has two operating segments which are both reportable business segments: (i) Product; and (ii) Service.

Comprehensive loss

For the  years  ended  December  31, 2018  , 2017 and  2016,  the  only  component  of  other  comprehensive  loss  was  unrealized  (losses)  gains  on  available-for-sale
securities.

Related party transactions

During  the  years  ended  December  31,  2018  , 2017 and 2016 ,  the  Company  had  revenue  transactions  with  a  related  party,  the  University  of  Chicago  Medical
Center (UCMC), for $0.4 million , $0.4 million and $0.4 million , respectively, relating to consulting services and technology solutions. One of the Company's
board members is the President of UCMC.

Recently adopted accounting pronouncement

In  May  2014,  the  Financial  Accounting  Standards  Board  (FASB)  together  with  the  International  Accounting  Standards  Board  issued  converged  guidance  for
revenue  recognition  that  replaces  most  existing  guidance,  eliminates  industry-specific  guidance  and  provides  a  unified  model  for  determining  how  and  when
revenue from contracts with customers should be recognized. Under the new guidance, 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.

The new guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the
cumulative effect of initially applying the guidance recognized at the date of initial application (modified retrospective method). 

The Company adopted the new guidance on January 1, 2018 using the full retrospective method, which requires the Company to present its historical financial
information for fiscal years 2017 and 2016 as if the new revenue guidance had been applied to all prior periods.  Refer to Note 2 for the details of the impact to
previously reported results.

In  October  2016,  the  FASB  issued  amended  guidance  on  the  accounting  for  income  taxes.  The  new  guidance  requires  the  recognition  of  the  income  tax
consequences  of  an  intercompany  asset  transfer,  other  than  transfers  of  inventory,  when  the  transfer  occurs.    The  guidance  is  effective  for  reporting  periods
beginning after December 15, 2017, with early adoption permitted. The adoption of this standard did not have a material impact on the Company’s consolidated
financial statements.

In January 2017, the FASB issued new guidance which clarifies the definition of a business to assist companies with evaluating whether transactions should be
accounted  for  as  acquisitions  of  assets  or  businesses.  The  new  guidance  requires  a  company  to  evaluate  if  substantially  all  of  the  fair  value  of  the  gross  assets
acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of assets and activities is not a business.
The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs
are  described  in  the  guidance  for  revenue  from  contracts  with  customers.  The  new  guidance  was  effective  for  the  Company  in  the  first  quarter  of  2018.  The
guidance was applied prospectively to any transactions occurring within the period of adoption. The adoption of this standard did not have a material impact on the
Company’s consolidated financial statements.

In May 2017, the FASB amended the scope of modification accounting for share-based payment arrangements. The guidance clarifies the type of changes to terms
or conditions of share-based payment awards to which an entity would be required to apply modification accounting. Specifically, under this guidance, an entity
would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the
modification. The new

59

Table of Contents

standard is effective for the Company in the first quarter of 2018. The guidance was applied prospectively to awards modified on or after the adoption date. The
adoption of this standard did not have a material impact on the Company’s consolidated financial statements.

Recent accounting pronouncements

In February 2016, the FASB amended lease accounting requirements to begin recording assets and liabilities arising from leases on the balance sheet. The new
guidance  will  also  require  significant  additional  disclosures  about  the  amount,  timing  and  uncertainty  of  cash  flows  from  leases.  This  new  guidance  will  be
effective  beginning  on  January  1,  2019  under  a  modified  retrospective  approach.  The  modified  retrospective  approach  includes  a  number  of  optional  practical
expedients that entities may elect to apply. The Company will elect the package of practical  expedients permitted under the transition guidance within the new
standard, which among other things, allows us to carryforward the historical lease classification. The Company will make an accounting policy election to keep
leases  with  an  initial  term  of  12  months  or  less  off  of  the  balance  sheet.  The  Company  will  recognize  those  lease  payments  in  the  consolidated  statements  of
operations on a straight-line basis over the lease term. The Company estimates the adoption of the standard will result in recognition of right-of-use assets, which
includes the impact of existing deferred rents and tenant improvement allowances of $5.1 million and lease liabilities of $6.7 million , respectively as of January 1,
2019. The Company does not believe the standard will materially affect our consolidated net earnings. These are preliminary estimates that are subject to change as
we finalize our adoption.

In  June  2016,  the  FASB  issued  new  guidance  related  to  the  accounting  for  credit  losses  on  instruments  for  both  financial  services  and  non-financial  services
entities. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the
impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since
their origination. The guidance will be effective beginning January 1, 2020. Early adoption is permitted. The Company is currently evaluating the impact of this
new guidance on its consolidated financial statements.

In  January  2017,  the  FASB  issued  new  guidance  to  simplify  the  accounting  for  goodwill  impairment.  The  guidance  simplifies  the  measurement  of  goodwill
impairment by removing step 2 of the goodwill impairment test, which requires the determination of the fair value of individual assets and liabilities of a reporting
unit.  The new guidance requires goodwill impairment to be measured as the amount by which a reporting unit’s carrying value exceeds its fair value; however, the
loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments should be applied on a prospective basis.  The
new  standard  is  effective  for  fiscal  years  beginning  after  December  15,  2019  with  early  adoption  permitted  for  interim  or  annual  goodwill  impairment  tests
performed after January 1, 2017. The Company is evaluating the impact of this new accounting guidance on its consolidated financial statements.

In February 2018, the FASB issued new guidance which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded
tax effects resulting from the Tax Cuts and Jobs Act and required certain disclosures about stranded tax effects. This standard will be effective for the Company
beginning January 1, 2019 and may be applied either in the period of adoption or retrospectively. Early adoption is permitted. The adoption of this guidance is not
expected to have a material impact on the Company’s consolidated financial statements.

In August 2018, the SEC adopted the final rule under SEC Release No. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements
that  were  redundant,  duplicative,  overlapping,  outdated  or  superseded.  In  addition,  the  amendments  expanded  the  disclosure  requirements  on  the  analysis  of
stockholders' equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders' equity presented in the balance
sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period
for which a statement of comprehensive income is required to be filed. This final rule was effective on November 5, 2018. The Company is evaluating the impact
of this guidance on its condensed consolidated financial statements and expects to adopt this guidance in the first quarter of fiscal 2019.

2.

Revenue, deferred revenue and deferred commissions

Effective  January  1,  2018,  the  Company  adopted  ASC  606  using  the  full  retrospective  method,  which  requires  the  Company  to  present  its  historical  financial
information for fiscal years 2017 and 2016 as if the new revenue guidance had been applied to all prior periods. 

The most significant impact of the standard relates to the timing of revenue recognition for software licenses sold with professional services where the Company
did not have vendor specific objective evidence (VSOE) for professional services under prior guidance.  Under the new standard, the requirement to have VSOE
for undelivered elements is eliminated and the Company recognizes revenue for software licenses upon transfer of control to its customers. Additionally, the new
standard requires the capitalization

60

Table of Contents

and amortization of costs related to obtaining a contract, such as sales commissions, which were previously recorded as an expense to sales and marketing at the
time incurred.

The core principle of ASC 606 is to 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. This principle is achieved through applying the following five-step approach:

•

•

•

•

Identification of the contract, or contracts, with a customer - A contract with a customer exists when (i) the Company enters into an enforceable contract
with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or
services,  (ii)  the  contract  has  commercial  substance  and,  (iii)  the  Company  determines  that  collection  of  substantially  all  consideration  for  goods  or
services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. The Company applies judgment in
determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience or,
in the case of a new customer, published credit and financial information pertaining to the customer. Customer payments received by the Company are
non-refundable.

Identification  of  the  performance  obligations  in  the  contract  -  Performance  obligations  promised  in  a  contract  are  identified  based  on  the  goods  or
services that will be transferred to the customer that are capable of being both: a) functionally distinct, whereby the customer can benefit from the goods
or service  either  on their  own or together  with other  resources  that  are  readily  available  from  third  parties  or from  the Company, and  b) contractually
distinct,  whereby  the  transfer  of  the  goods  or  services  is  separately  identifiable  from  other  promises  in  the  contract.  To  the  extent  a  contract  includes
multiple promised goods or services, the Company applies judgment to determine whether promised goods or services are capable of being distinct and
distinct in the context of the contract. If these criteria are not met the promised goods or services are accounted for as a combined performance obligation.

Determination  of  the  transaction  price  -  The  transaction  price  is  determined  based  on  the  consideration  to  which  the  Company  will  be  entitled  in
exchange for transferring goods or services to the customer.

Allocation  of the transaction price to the performance obligations in the contract - If the contract contains a single performance obligation, the entire
transaction price is allocated  to the single performance  obligation. Contracts that contain multiple performance obligations require an allocation of the
transaction price to each performance obligation based on a relative standalone selling price, (SSP) basis. The Company determines standalone selling
price based on the price at which the performance obligation is sold separately. If the standalone selling price is not observable through past transactions,
the Company estimates the standalone selling price taking into account available information such as market conditions and internally approved pricing
guidelines related to the performance obligations.

•

Recognition of revenue when, or as, the Company satisfies a performance obligation - The Company satisfies performance obligations either over time or
at a point in time as discussed in further detail below. Revenue is recognized at the time the related performance obligation is satisfied by transferring a
promised good or service to a customer.

Disaggregation of Revenue

A  typical  sales  arrangement  involves  multiple  arrangements,  such  as  sales  of  the  Company’s  proprietary  communication  device  ("Vocera  Badge"),  perpetual
software licenses, professional services, and maintenance and support services which entitle customers to unspecified upgrades, patch releases and telephone-based
support.  The  following  table  depicts  the  disaggregation  of  revenue  according  to  revenue  type  and  is  consistent  with  how  the  Company  evaluates  its  financial
performance:

Device revenue - In transactions where the Company delivers hardware, the Company considers itself to be the principal in the transaction and records

revenue and costs of goods sold on a gross basis. Hardware revenue is generally recognized upon transfer of control to the customer.

Software revenue - Revenue from the Company’s software products is generally recognized upon transfer of control to the customer.

Maintenance and support revenue - The Company generates maintenance and support revenue primarily from post contract support (PCS) contracts, and,
to a lesser extent, from sales of extended warranties on the Vocera Badge. The majority of software sales are in conjunction with PCS contracts, which generally
have one-year terms. The Company recognizes revenue from PCS contracts ratably over the contractual service period. The service period typically commences
upon transfer of control of the corresponding software products to the customer. The Company recognizes revenue from extended warranty contracts ratably over
their contractual service period, which is typically one year. This period starts one year from the date on which the transfer of control on the underlying hardware
occurs because the hardware generally carries a one-year warranty.

Professional  services  and  training  revenue  -  Professional  services  and  training  revenue  is  generated  when  the  Company  installs  and  configures  its

software and devices at new or existing customer sites. The Company recognizes revenue related to professional services as they are performed.

Contracts with multiple performance obligations - Some of the Company’s contracts with customers contain multiple performance obligations. For these
contracts,  the  Company  accounts  for  individual  performance  obligations  separately  if  they  are  distinct.  The  transaction  price  is  allocated  to  the  separate
performance obligations on a relative stand-alone selling price basis. For deliverables that are routinely sold separately, such as maintenance and support on the
core offerings, the Company determines SSP by evaluating renewals over the trailing 12-months. For those that are not sold routinely, the Company determines
SSP based on its overall pricing trends and objectives, taking into consideration market conditions and other factors, including the value of the contracts and the
products sold.

Contract  balances  -  The  timing  of  revenue  recognition,  billings  and  cash  collections  result  in  billed  accounts  receivable,  unbilled  accounts  receivable
(contract  asset).  Accounts  receivable  are  recorded  at  the  invoiced  amount.  A  receivable  is  recognized  in  the  period  the  Company  delivers  goods  or  provides
services or when the right to consideration is unconditional. Payment terms on invoiced amounts are typically 30 days. The balance of accounts receivable, net of
allowance for doubtful accounts, as of

December  31,  2018  and  2017  is  presented  in  the  accompanying  consolidated  balance  sheets.  As  of  December  31,  2018  and  2017  contract  assets  totaled  $2.4
million and $0.2 million .

Costs to obtain and fulfill a contract - The Company capitalizes certain incremental contract acquisition costs consisting primarily of commissions paid
and  the  related  payroll  taxes  when  customer  contracts  are  signed.  The  Company  determines  whether  costs  should  be  deferred  based  on  its  sales  compensation
plans,  if  the  commissions  are  incremental  and  would  not  have  been  incurred  absent  the  execution  of  the  customer  contract.  Sales  commissions  for renewals  of
customer contracts are not commensurate with the commissions paid for the acquisition of the initial contract given the substantive difference in commission rates
in proportion to their respective contract values. Commissions paid upon the initial acquisition of a contract are amortized over the estimated period of benefit,
which may exceed the term of the initial contract. Accordingly, amortization of deferred costs is recognized on a systematic basis that is consistent with the pattern
of revenue recognition allocated to each performance obligation and is included in sales and marketing expense in the consolidated statements of operations. The
Company determines its estimated period of benefit, up to five years, by evaluating the expected renewals of its customer contracts, the duration of its relationships
with its customers and other factors. Deferred costs are periodically reviewed for impairment. Changes in the balance of total deferred commissions (contract asset)
during the year ended December 31, 2018 and 2017 are as follows:

expense over the next 12 months and the remainder thereafter.

Deferred  revenue  -  The  Company  records  deferred  revenue  when  cash  payments  are  received  in  advance  of  the  performance  under  the  contract.  The
current portion of deferred revenue represents the amounts that are expected to be recognized as revenue within one year of the consolidated balance sheet date.

3. Fair value of financial instruments

The carrying values of the Company’s cash and cash equivalents and short-term investments approximate their fair value due to their short-term nature. As a basis
for determining the fair value of its assets and liabilities, the Company utilizes a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair
value  as  follows:  (Level  1)  observable  inputs  such  as  quoted  prices  in  active  markets;  (Level  2)  inputs  other  than  the  quoted  prices  in  active  markets  that  are
observable either directly or indirectly; and (Level 3) unobservable inputs in which there is little or no market data which requires the Company to develop its own
assumptions.  This  hierarchy  requires  the  Company  to  use  observable  market  data,  when  available,  and  to  minimize  the  use  of  unobservable  inputs  when
determining fair value. For the years ended December 31, 2018 , 2017 and 2016 , there have been no transfers between Level 1 and Level 2 fair value instruments
and no transfers in or out of Level 3.

The Company's money market funds are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices. The fair value of
the Company's Level 2 fixed income securities are obtained from independent pricing services, which may use quoted market prices for identical or comparable
instruments  or model-driven  valuations using observable  market data or other inputs corroborated by observable  market data. The Company does not have any
financial instruments which are valued using Level 3 inputs.

In addition to its cash, cash equivalents and short-term investments, the Company measures the fair value of its Convertible Senior Notes on a quarterly basis for
disclosure purposes. The Company considers the fair value of the Convertible Senior Notes at December 31, 2018 to be a Level 2 measurement due to limited
trading activity of the Convertible Senior Notes. Refer to Note 8 to the consolidated financial statements for further information.

The table below summarizes the Company’s assets that are measured at fair value on a recurring basis, by level, within the fair value hierarchy as of December 31,
2018 and 2017 , respectively.

values.

The  Company  has  determined  that  the  unrealized  losses  on  its  short-term  investments  as  of  December  31,  2018  and  2017  do  not  constitute  an  "other  than
temporary  impairment".  The unrealized  losses for the  short-term  investments  as of  December  31, 2018  and 2017 have all  been in  a continuous  unrealized  loss
position for less than twelve months. The Company’s conclusion of no “other than temporary impairment” is based on the high credit quality of the securities, their
short remaining maturity and the Company’s intent and ability to hold such loss securities until maturity.

Classification of the cash, cash equivalent and short-term investments by contractual maturity was as follows:

The Company had $49.2 million and $49.2 million of goodwill as of December 31, 2018 and 2017 , respectively. Goodwill is tested for impairment at the reporting
unit level at least annually or more often if events or changes in circumstances indicate the carrying value may not be recoverable. The Company has two reporting
units: Product and Service. As of December 31, 2018 , $41.2 million of the Company's goodwill resides in the Product reporting unit and $8.0 million resides in the
Service reporting unit. The Company performed an impairment assessment in 2018 which determined that no impairment existed. For the years ended December
31,  2018  and  2017,  the  Company  used  the  qualitative  assessment  permitted  under  authoritative  accounting  guidance.  Among  the  qualitative  factors  considered
were changes since the prior impairment test in the following: industry and competitive environment, business strategy, product mix, buyer and supplier bargaining
power,  potential  market  size,  consistency  in  operating  margins  and  cash  flows,  change  in  reporting  unit  or  product  life  cycle  stage  and  earnings  quality  and
sustainability. No impairment was recorded in the years ended December 31, 2018 , 2017 or 2016 .

Intangible assets

The  fair  values  for  acquired  intangible  assets  were  determined  by  management  with  consideration  of,  in  part,  valuations  performed  by  independent  valuation
specialists. Acquisition-related intangible assets are amortized over the life of the assets on an accelerated basis that approximates the expected economic benefit of
the  assets.  This  assumption  results  in  amortization  that  is  higher  in  earlier  periods  of  the  useful  life.  To  date  there  has  been  no  impairment  of  the  Company's
intangible assets. The estimated useful lives and carrying value of acquired intangible assets are as follows:

principal  amount  of  such  notes  pursuant  to  the  exercise  in  full  of  options  granted  to  the  initial  purchasers,  collectively  the  “Notes.”  The  Notes  are  unsecured,
unsubordinated  obligations  and  bear  interest  at  a  fixed  rate  of  1.50% per  annum,  payable  semi-annually  in  arrears  on  May  15  and  November  15  of  each  year,
commencing on November 15, 2018. The total net proceeds from the offering, after deducting initial purchase discounts and estimated debt issuance costs, were
approximately $138.9 million .

Each $1,000 principal amount of the Notes will initially be convertible into 31.0073 shares of the Company’s common stock, the “Conversion Option,” which is
equivalent  to  an  initial  conversion  price  of  approximately  $32.25 per  share,  subject  to  adjustment  upon  the  occurrence  of  specified  events.  The  Notes  will  be
convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding February 15, 2023, only under the
following circumstances:

(1)  during  any  calendar  quarter  commencing  after  the  calendar  quarter  ending  on  June  30,  2018  (and  only  during  such  calendar  quarter),  if  the  last
reported sale price of the Company common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending
on the last trading day of the immediately  preceding  calendar quarter  is greater  than or equal to 130% of the conversion price of the Notes on each applicable
trading day;

(2) during the five business day period after any ten consecutive trading day period in which the trading price per $1,000 principal amount of the Notes
for each day of that ten day consecutive trading day period was less than 98% of the product of the last reported sale price of the Company’s common stock and the
conversion rate of the Notes on such trading day; or

(3) upon the occurrence of specified corporate events (as set forth in the indenture governing the Notes).

On or after February 15, 2023 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their
Notes  at  any  time,  regardless  of  the  foregoing  circumstances.  Upon  conversion,  the  Company  will  pay  or  deliver,  as  the  case  may  be,  cash,  shares  of  the
Company’s  common  stock  or  a  combination  of  cash  and  shares  of  the  Company’s  common  stock,  at  the  Company’s  election.  If  certain  specified  fundamental
changes occur (as set forth in the indenture

Table of Contents

governing  the  Notes)  prior  to  the  maturity  date,  holders  of  the  Notes  may  require  the  Company  to  repurchase  for  cash  all  or  any  portion  of  their  Notes  at  a
repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change
repurchase date. In addition, if specific corporate events occur prior to the applicable maturity date, the Company will increase the conversion rate for a holder who
elects to convert their notes in connection with such a corporate event in certain circumstances. It is the Company’s current intent and policy to settle conversions
through combination settlement which involves repayment of the principal portion in cash and any excess of the conversion value over the principal amount in
shares of its common stock. During the year ended December 31, 2018, the conditions allowing holders of the Notes to convert have not been met. The Notes are
therefore not convertible during the year ended December 31, 2018 and are classified as long-term debt.

In accounting for the transaction, the Notes were separated into liability and equity components. The carrying amount of the liability component was calculated by
measuring  the  fair  value  of  a  similar  debt  instrument  that  does  not  have  an  associated  convertible  feature.  The  carrying  amount  of  the  equity  component
representing the conversion option was $33.4 million and was determined by deducting the fair value of the liability component from the par value of the Notes.
The equity component was recorded in additional paid-in capital and will be remeasured as long as it continues to meet the conditions for equity classification. The
excess of the principal amount of the liability component over its carrying amount, the “debt discount,” is amortized to interest expense over the contractual term
of the Notes at an effective interest rate of 7.6% .

In  accounting  for  the  debt  issuance  costs  of  $4.9  million  related  to  the  Notes,  the  Company  allocated  the  total  amount  incurred  to  the  liability  and  equity
components of the Notes based on their relative values. Issuance costs attributable to the liability component were $3.8 million and will be amortized to interest
expense using the effective interest method over the contractual term of the Notes. Issuance costs attributable to the equity component were $1.1 million and are
included with the equity component in additional paid-in capital.

The Notes consist of the following:

The  total  estimated  fair  value  of  the  Notes  as  of  December  31,  2018  was  approximately    $210.6 million .  The  fair  value  was determined  based  on the  closing
trading  price  per  $100 of  the  Notes  as  of  the  last  day  of  trading  for  the  period.  The  fair  value  of  the  Notes  is  primarily  affected  by  the  trading  price  of  the
Company’s  common  stock  and  market  interest  rates.  Based  on  the  closing  price  of  the  Company’s  common  stock  of    $39.35  on  December  31,  2018,  the  if-
converted value of the Notes of $175.4 million  was greater than their principal amount.

Capped Calls

In connection with the pricing of the Notes, the Company entered into privately negotiated capped call transactions with certain counterparties, the “Capped Calls.”
The Capped Calls each have an initial strike price of approximately $32.25 per share, subject to certain adjustments, which correspond to the initial conversion
price of the Notes. The Capped Calls have initial cap prices of $38.94 per share, subject to certain adjustments. The Capped Calls cover, subject to anti-dilution
adjustments, approximately 4.5 million shares of the Company’s common stock. Conditions that cause adjustments to the initial strike price of the Capped Calls
mirror conditions that result in corresponding adjustments for the Notes. The Capped Calls are generally intended to reduce or offset the potential dilution to the
Company’s  common  stock  upon  any  conversion  of  the  Notes  with  such  reduction  or  offset,  as  the  case  may  be,  subject  to  a  cap  based  on  the  cap  price.  For
accounting purposes, the Capped Calls are separate transactions, and not part of the terms of the Notes. As these transactions meet certain accounting criteria, the
Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The cost of $8.9 million incurred in connection with the Capped Calls
was recorded as a reduction to additional paid-in capital.

The net impact to the Company’s stockholders' equity, included in additional paid-in capital, of the above components of the Notes is as follows:

The Notes will not have an impact on the Company’s diluted earnings per share until they meet the criteria for conversion, as discussed above, as the Company
intends to settle the principal amount of the Notes in cash upon conversion. Under the treasury stock method, in periods when the Company report net income, the
Company is required to include the effect of additional shares that may be issued under the Notes when the price of its’ common stock exceeds the conversion
price. However, upon conversion, there will be no economic dilution from the Notes until the average market price of the Company’s common stock exceeds the
cap price of $38.94  per share, as exercise of the capped calls offsets any dilution from the Notes from the conversion price up to the cap price. Capped Calls are
excluded from the calculation of diluted earnings per share, as they would be anti-dilutive under the treasury stock method.

9. Commitments and contingencies

Non-cancelable purchase commitments

The Company enters into non-cancelable purchase commitments with its third-party manufacturers whereby the Company is required to purchase any inventory
held  by  the  third-party  manufacturer  that  have  been  purchased  by  them  based  on  confirmed  orders  from  the  Company.  As  of  December  31,  2018  and 2017 ,
approximately $11.1 million and $4.4 million , respectively, of raw material inventory was purchased and held by the third-party manufacturer which was subject
to such purchase requirements.

Leases

The  Company  leases  office  space  for  its  headquarters  and  subsidiaries  under  non-cancelable  operating  leases,  which  will  expire  between  January  2019  and
February 2023. Total rent expense for the years ended December 31, 2018 , 2017 and 2016 was $2.7 million , $2.6 million and $2.4 million , respectively. The
Company recognizes rent expense on a straight-line basis over the lease period and has accrued for rent expense incurred but not paid.

The Company undertakes, in the ordinary course of business, to (i) defend customers and other parties from certain third-party claims associated with allegations of
trade secret misappropriation, infringement of copyright, patent or other intellectual property right, or tortious damage to persons or property and (ii) indemnify
and  hold  harmless  such  parties  from  certain  resulting  damages,  costs  and  other  liabilities.  The  term  of  these  undertakings  may  be  perpetual  and  the  maximum
potential liability of the Company under certain of these undertakings is not determinable. Based on its historical experience, the Company believes the liability
associated with these undertakings is minimal.

The Company has entered  into  indemnification  agreements  with its directors  and officers  that may require  the Company to indemnify  its  directors  and officers
against liabilities that may arise by reason of their status or service as directors or officers, other than liabilities arising from willful misconduct of the individual.
The Company currently has directors and officers insurance. As there has been no significant history of losses, no expense accrual has been made.

Litigation         

The Company is currently, and from time to time, the Company may be, involved in lawsuits, claims, investigations and proceedings, consisting of intellectual
property, commercial, employment and other matters which arise in the ordinary course of business. The Company defends itself vigorously against any such
claims. Although the outcome of these matters is currently not determinable, management expects that any losses from existing matters that are probable or
reasonably possible of being incurred as a result of these matters would not be material to the financial statements as a whole.

10. Common Stock and Share-based Compensation

The Company’s certificate of incorporation, as amended, authorizes the Company to issue 100 million shares of $0.0003 par value common stock.

At December 31, 2018 , the Company has 2,377,888 shares of common stock reserved for issuance under stock option plans.

Incentive stock option plans

The Company has four equity incentive plans: the 2000 Stock Option Plan (the 2000 Plan), the 2006 Stock Option Plan (the 2006 Plan), the 2012 Stock Option
Plan (the 2012 Plan) and the 2016 Equity Inducement Plan (the 2016 Plan). On March 26, 2012, all shares that were reserved under the 2006 Plan but not subject to
outstanding awards became available for grant under the 2012 Plan. No additional shares will be issued under the 2006 Plan. The 2000 Plan terminated in March
2010 and no additional shares will be issued under this plan. All options currently outstanding under the 2000 Plan and the 2006 Plan continue to be governed by
the terms and conditions of those plans. The 2016 Plan was adopted by the Company's Board of Directors without shareholder approval pursuant to the inducement
exemption provided under the NYSE listing rules for the issuance of restricted stock units (RSUs) to employee's who joined the Company after the acquisition of
Extension Healthcare. No additional shares will be issued under the 2016 Plan. Under the 2012 Plan, the Company has the ability to issue incentive stock options
(ISOs), stock appreciation rights, restricted stock awards, RSUs, performance awards and stock bonuses. The ISOs will be granted at a price per share not less than
the fair value at date of grant.

Employee Stock Purchase Plan

The  Company's  2012  Employee  Stock  Purchase  Plan  (ESPP)  allows  eligible  employees  to  purchase  shares  of  common  stock  at  a  discount  through  payroll
deductions of up to 15% of their eligible compensation, subject to any plan limitations. The ESPP provides for six -month offering periods.

At the end of each offering period, eligible employees are able to purchase shares at 85% of the lower of the fair market value of the Company's common stock on
the first trading day of the offering period or on the last day of the offering period. During the years ended December 31, 2018 and 2017 , employees purchased
157,426 and 159,532 shares, respectively, of common stock at an average purchase price of $20.77 and $17.23 , respectively. As of December 31, 2018 , 721,303
shares remained available for future issuance under the ESPP.

The Company uses the Black-Scholes option-pricing model to calculate the fair value of periodic ESPP offerings on their offer date. The following assumptions
were used for each respective period for the ESPP:

Volatility

Risk-free interest rate

Dividend yield

Allocation of Stock-Based Compensation Expense

Stock-based compensation expense is recognized based on a straight-line amortization method over the respective vesting period of the award. For the years ended
December 31, 2017 and 2018 the straight-line amortization is reduced by actual forfeitures. For the year ended December 31, 2016 the straight-line amortization
has been reduced for estimated forfeitures. The Company estimated the expected forfeiture rate based on its historical experience, considering voluntary
termination behaviors, trends of actual award forfeitures, and other events that will impact the forfeiture rate. To the extent the Company’s actual forfeiture rate is
different from the estimate, the stock-based compensation expense is adjusted accordingly.

The Company has two operating segments which are both reportable segments: (i) Product; and (ii) Service, which are comprised of the Company’s and its wholly-
owned subsidiaries’ results from operations. Operating segments are defined as components of an enterprise about which separate financial information is available
that  is  evaluated  regularly  by  the  chief  operating  decision  maker  (CODM),  or  decision-making  group,  in  deciding  how  to  allocate  resources  and  in  assessing
performance. The Company’s CODM is its Chief Executive Officer.

The CODM regularly receives information  related to revenue, cost of revenue, and gross profit for each operating segment, and uses this information to assess
performance  and  make  resource  allocation  decisions.  All  other  financial  information,  including  operating  expenses  and  assets,  is  prepared  and  reviewed  by  the
CODM on a consolidated basis.

Assets are not a measure used to assess the performance of the Company by the CODM, therefore the Company does not report assets by segment internally or in
its financial statements.

The Company's deferred tax liabilities are primarily related to tax deductible goodwill. The Company determines its valuation allowance on deferred tax assets by
considering  both  positive  and  negative  evidence  in  order  to  ascertain  whether  it  is  more  likely  than  not  that  deferred  tax  assets  will  be  realized.  Realization  of
deferred tax assets is dependent upon the generation of future taxable income, if any, the timing and amount of which are uncertain. Due to the history of losses the
Company  has  generated  in  the  past,  the  Company  believes  that  it  is  not  more  likely  than  not  that  all  of  the  deferred  tax  assets  in  the  U.S.  and  Canada  can  be
realized as of December 31, 2018 ; accordingly, the Company has recorded a full valuation allowance on its deferred tax assets.

On December 22, 2017, the Tax Cuts and Jobs Act (P.L. 115-97) was signed into law. Among other changes is a permanent reduction in the federal corporate
income  tax  rate  from  35% to 21% effective  January  1,  2018.  As  a  result  of  the  reduction  in  the  corporate  income  tax  rate,  the  Company  has  revalued  its  net
deferred tax liability at December 31, 2017. This resulted in a reduction in the value of the Company's net deferred tax asset of approximately $19.0 million , which
is offset by the change in valuation allowance of $19.7 million . This resulted in a deferred tax benefit of $0.7 million recorded in the statement of operations in the
three months ended December 31, 2017.

The Act includes certain anti-deferral and anti-abuse erosion provisions, including a new minimum tax on global intangible low-taxed income ('GILTI'). The Act
subjects the Company to current tax on GILTI of its controlled foreign corporations. At December 31, 2018, the Company recognized $1.1 million GILTI inclusion
reducing the deferred tax assets, which will be fully offset by the change in valuation allowance. There is no tax expense impact related to GILTI inclusion

The Company’s valuation allowance increased by $5.2 million and $2.9 million for the years ended December 31, 2018 and 2017 , respectively. The change in the
2018 valuation allowance was primarily due to the addition of current year loss carryforwards

and federal rate reduction. The change in the 2017 valuation allowance was primarily due to the addition of current year loss carryforwards.

At December  31,  2018  ,  the  Company  had  $124  million  and $63  million  ,  respectively,  of  federal  and  state  net  operating  loss  carryforwards.  The  federal  net
operating loss carryforward generated in the years ended December 31, 2002 through 2017 begin expiring in 2022.

Net operating losses originating before January 1, 2018 are eligible to offset taxable income, if not otherwise limited under IRS Section 382. Net operating losses
generated after December 31, 2017 have an infinite carryforward period and subject to 80% deduction limitation based upon pre-net operating deduction taxable
income.

The state net operating loss carryforward begins expiring in 2030, if not utilized.

In addition, the Company has federal research and development tax credits carryforwards of approximately $3.9 million and state research and development tax
credit carryforwards of approximately $5.3 million . The federal credit carryforwards begin expiring 2026 and the state credits carry forward  indefinitely . The
Internal Revenue Code (IRC) contains provisions which limit the amount of net operating loss (NOL) and research credit carryforwards that can be used in any
given year if a significant change in ownership has occurred. As of December 31, 2018, $11.5 million of the Company's NOL carryovers and $0.5 million of credit
carryovers  are  subject  to  an  annual  $0.6 million limitation,  of  which  $5.3 million NOLs  would  be  available  to  offset  future  taxable  income  in  the  twenty-year
carryforward period.

As a result of the Company’s historical losses and related valuation allowances, the Company has recorded substantially all of the uncertain tax amounts above as
reductions to deferred tax assets which are subject to a full valuation allowance in its consolidated balance sheet with an insignificant portion recorded in other
long-term liabilities. The Company recognizes interest and penalties relating to uncertain tax positions in income tax expense. As the Company is not currently
under examination, it is reasonable to assume that the balance of gross unrecognized tax benefits will likely not change in the next twelve months.

The Company files income tax returns in the United States on a federal basis and in various states. The Company is not currently under any international or any
United States federal, state and local income tax examinations for any taxable years. All of the Company’s net operating losses and research credit carryforwards
prior to 2018 are subject to tax authority adjustment and all years after 2011 are still subject to the tax authority examinations.

The  2017  tax  reform  legislation  provides  for  a  one-time  “deemed  repatriation”  of  accumulated  foreign  earnings  for  the  year  ended  December  31,  2017.  The
Company does not expect to pay U.S. federal cash taxes on the deemed repatriation due to its historical net operating loss for tax purposes. The Company does not
expect that the future foreign earnings will be subject to U.S. federal income tax since the Company intends to continue reinvesting such earnings outside the U.S.
indefinitely. On December 22, 2017, the SEC issued Staff Accounting Bulletin 118 (“SAB 118”), which provides guidance on accounting for tax effects of the Tax
Act.

SAB 118’s measurement period closed on December 22, 2018, one year from the Tax Act enactment. The Company completed its accounting for the impact of the
Tax Act and there were no subsequent revisions from the provisional amounts recorded in the prior year financial statements.

13. Business acquisitions

Acquisition of Extension Healthcare

On October 27, 2016 , the Company acquired all of the outstanding equity interest of Extension Healthcare for $52.5 million in cash. The Company incurred $5.8
million in merger and integration costs for the year ended December 31, 2016, which were recorded in cost of revenue and operating expenses in the consolidated
statements of operations.

Based  in  Fort  Wayne,  Ind.,  Extension  Healthcare  is  a  provider  of  clinical,  event-driven  communication  and  workflow  collaboration  software  for  the  hospital
environment. Extension Healthcare is known in the market for its clinical integration software solution Engage, which features an advanced clinical rules engine
that  unifies  data  from  multiple  sources  simultaneously,  enables  prioritization  of  notifications,  adds  patient  context,  and  sends  messages  to  the  right  care  team
members on their mobile devices. The Engage platform allows clinicians to be away from the bedside while staying informed about their patients.

The amortization of developed technology and backlog is recorded in "cost of revenues" for product and the amortization for the remaining intangibles is recorded
in "sales and marketing" expenses on the consolidated statement of operations.

The excess of the acquisition consideration over the fair values of the underlying net assets acquired was recorded as goodwill. Goodwill is largely attributable to
the synergy of Extension Healthcare’s proprietary solutions with the Company’s existing customer base, dedicated sales force and cross selling opportunities with
the Company’s other solutions. Goodwill is not amortized but instead is tested for impairment at least annually or more frequently if indicators of impairment are
present. For federal income tax purposes, the entire purchase consideration, including goodwill, is capitalizable and deductible over fifteen years. The goodwill

80

Table of Contents

recorded from the acquisition of Extension Healthcare was allocated with $31.2 million attributable to the Product reporting unit and $8.0 million attributable to
the Service reporting unit.

In connection with the acquisition the Company recorded a charge of $2.6 million related to the planned redistribution of proceeds by the selling shareholders to
employees of Extension Healthcare who will be retained by the Company post-acquisition. (Employee Payments). These payments are not dependent on continued
employment  with  the  Company  and  will  be  reduced  by  any  escrow  claims  made  by  the  Company  prior  to  redistribution.  Under  GAAP,  including  guidance
promulgated  by the  U.S. Securities  and Exchange  Commission,  actions  of economic  interest  holders  in a  company  may  be imputed  to  the  company  itself.  The
selling shareholders of Extension Healthcare meet the criteria of economic interest holders of the Company due to their ability to earn additional consideration in
connection with the close of escrow. As such, the redistribution of this portion of the purchase price to the acquired employees who did not have a right to such
payments based on their existing interest in Extension Healthcare at the time of acquisition are deemed to represent payments for services that benefit the Company
and must therefore be recorded as non-cash compensation expense incurred by the Company and a capital contribution received from the selling shareholders. In
substance, the Employee Payments are a second and separate transaction from the acquisition of Extension Healthcare, which is recorded as a separate non-cash
accounting entry.

Additionally, in connection with the acquisition the Company established a retention bonus plan for Extension Healthcare with potential additional compensation
over a two -year period of approximately $2.6 million , based on continued employment. Such amounts are not considered part of the purchase consideration and
are being recorded as compensation expense as earned. During the years ended December 31, 2018, 2017 and 2016, $0.5 million , $1.0 million and $0.5 million ,
respectively, of this retention bonus was paid and $0.3 million , $1.0 million and $0.7 million , respectively, was recorded as compensation expense.

Immediately subsequent to the acquisition the Company initiated a restructuring plan which resulted in $0.5 million of severance charges of which $0.1 million
was recorded to cost of revenue and $0.4 million was recorded to operating expenses. Substantially all of the amounts have been paid as of December 31, 2016.

The results of operations of Extension Healthcare are included in Vocera's consolidated results of operations beginning in the fourth quarter of fiscal 2016. For the
fiscal year ended December 31, 2016, immaterial revenue and operating loss of approximately  $7.1 million  attributable to Extension Healthcare were included in
the consolidated results of operations.

The unaudited  pro forma  financial  information  for  the  years  ended December  31, 2016 is presented  as if the acquisition  had occurred  on January  1, 2016. The
historical financial information is adjusted in the unaudited pro forma financial information to give effect to pro forma events that are (1) directly attributable to the
proposed acquisition, (2) factually supportable, and (3) expected to have a continuing impact on the combined results.

The  unaudited  pro  forma  financial  information  are  not  necessarily  indicative  of  or  intended  to  represent  the  results  that  would  have  been  achieved  had  the
transaction been consummated as of the dates indicated or that may be achieved in the future. The actual results reported by the combined company in periods
following the acquisition may differ significantly from those reflected in this unaudited pro forma financial information for a number of reasons, including cost
saving synergies from operating efficiencies and the effect of the incremental costs incurred to integrate the two companies.

Item 9A. Controls and Procedures     

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in reports filed or submitted under the Exchange Act is
recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Disclosure controls
and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in reports filed under the Exchange
Act is accumulated and communicated to management, including principal executive and principal financial officers, or persons performing similar functions, as
appropriate to allow timely decisions regarding required disclosure.

As of December 31, 2018 , we carried out an evaluation under the supervision of, and with the participation of our management, including our Chief Executive
Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and
15d-15(e)  of  the  Exchange  Act.  Based  on  our  evaluation,  our  Chief  Executive  Officer  and  Chief  Financial  Officer  concluded  that  our  disclosure  controls  and
procedures were effective as of December 31, 2018 .

Management's Report on Internal Control Over Financial Reporting

Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting  (as  defined  in  Rule  13a-15(f)  under  the
Exchange Act). Our management conducted an assessment of the effectiveness of our internal control over financial reporting based on the criteria set forth in the
2013 version of the Internal Control - Integrated Framework issued

by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (COSO).  Based  on  the  assessment,  management  has  concluded  that  our  internal
control over financial reporting was effective as of December 31, 2018 based on these criteria.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the three months ended December 31, 2018 that has materially affected,
or is reasonably likely to materially affect, our internal control over financial reporting.

Limitations on Effectiveness of Controls and Procedures and Internal Control over Financial Reporting

In designing and evaluating  the disclosure  controls and procedures  and internal  controls over financial  reporting,  management  recognizes  that any controls  and
procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of
disclosure  controls  and  procedures  and  internal  control  over  financial  reporting  must  reflect  the  fact  that  there  are  resource  constraints  and  that  management  is
required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.
