Item 1.

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 improve patient safety and experience, and increase operational efficiency. As of December 31, 2015, our
solutions had been selected by more than 1,400 facilities worldwide.

Our  Communication  solution,  which  includes  an  intelligent  enterprise  software  platform;  a  lightweight,  wearable,  voice-controlled  communication  badge;  and
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
securely delivers text messages and alerts directly to and from smartphones, replacing legacy pagers.

At  the  core  of  our  Communication  solution  is  a  patent-protected,  enterprise-class  server  software  platform.  Our  software  platform  is  built  upon  a  scalable
architecture  and recognizes more than 100 spoken commands. Users can instantly communicate  with others using the Vocera communication badge or through
client applications for iPhone and Android devices. Our solution 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 company. Our Communication solution can be integrated with
other  clinical  systems,  including  Electronic  Health  Records  (EHR),  nurse  call,  and  patient  monitoring,  to  provide  critical  data,  alerts  and  clinical  context,  and
enable consistent workflows. Today, we have integrations with more than 70 other clinical systems. We have recently expanded our Communication solution to
include our Clinical Workflow Engine, which provides connectivity to leading nurse call and physiological monitors and includes alarm analytics software that
enables  nurses  and  clinicians  to  view,  prioritize  and  respond  to  critical  alarms  and  set  better  alarm  policies  via  intelligent  analytics,  which  helps  reduce  alarm
fatigue and improve patient safety.

Beyond  healthcare,  our  Communication  solution  is  used  to  quickly  and  contextually  connect  staff  in  other  mission-critical  mobile-worker  environments.  Our
communication  solution  is  used  in  the  nuclear  power  industry  to  facilitate  instant,  efficient  communications  during  maintenance  shutdowns.  In  the  hospitality
industry, Vocera connects front-of-house and back-of-house staff to improve guest experience and staff productivity.

Over our 16-year history, we have significantly enhanced and added features and functionality to this solution through ongoing development based on frequent
interactions with our customers.

Vocera  Care  Experience  is  a  hosted  software  solution  suite  that  coordinates  and  streamlines  provider-to-patient  and  provider-to-provider  communication  to
improve patient safety and experience, reduce care provider's risk and improve reimbursements.  The

3

Table of Contents

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 and staff experience.

As of December 31, 2015, our solutions were selected by over 1,150 hospitals and healthcare facilities, including large hospital systems, small and medium-sized
local  hospitals,  and  a  small  number  of  clinics,  surgery  centers  and  aged-care  facilities.  Over  1,400 facilities,  including  non-healthcare  users,  have  selected  our
solutions. 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, CA 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 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 changes occurring in the healthcare industry enhance the need for better communication to meet increasing requirements for care quality,
patient  safety,  efficiency  and  patient  satisfaction.  These  changes  also  require  greater  coordination  of  care  among  clinicians  for  the  industry’s  shift  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  and  to  improve  safety,  quality  and  cost  of  care  and  patient  satisfaction.  Our  communication  and  patient  experience  solutions  help
hospitals increase productivity and reduce costs by streamlining operations, improving patient and staff satisfaction by enabling secure, integrated and intelligent
communication.

We also serve other industries, including hospitality, nuclear energy and education. In the hospitality industry, our Communication solution can be used to increase
guest experience and loyalty, as well as staff productivity and responsiveness. In the nuclear energy industry, Vocera can be used to instantly connect people and
resources,  reducing  turnaround  times  and  workers’  exposure  to  radiation.  Schools  can  leverage  our  Communication  solution  to  increase  security  and  staff
communication, and libraries can use our Communication solution to enable their librarians to be more mobile and attentive to their patrons.

Our strategy

Our goal is to extend our leadership position as a provider of communication 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 communication and collaboration platform can provide significant value to both
large and small hospitals. We plan to continue to add new customers among hospitals of all sizes, and expand to outpatient clinics, skilled nursing facilities
and physician practices. We have structured and incentivized our sales organization to focus on sales to new customer sites, particularly within large health
systems.
Further penetrate our existing installed customer base.     Typically, our customers initially deploy our Communication solution in a few departments of a
hospital and gradually expand to additional departments as they come to fully appreciate the value of our solution. We recognize the 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 promoting further adoption of our Communication solution, and demonstrating the value of our new solutions to our existing customers. We

4

•

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 communication solutions and further differentiate them from other competing solutions. We plan to invest in product upgrades, product
line extensions and new solutions to enhance our portfolio, including further development of applications for iPhone and Android devices.
Invest in partnerships. In order to gain access to clinical data and patient context needed to create a highly efficient communication 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 and
EHRs. We are developing a range of business partnerships to broaden our overall market presence and accelerate the sales of our offerings.
Pursue acquisitions of complementary businesses, technologies and assets.     We have completed six small acquisitions since 2010 to expand our solutions
offering, 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 and New Zealand. As of December 31, 2015, our solutions were selected by over 170 healthcare facilities outside the United
States. We plan both to utilize our direct sales force and leverage channel partners to expand our presence in other English-speaking markets. We have also
introduced localized versions of our Communication solution for English speakers in Singapore, Malaysia and Middle Eastern countries including the United
Arab Emirates and Saudi Arabia. We believe that the rapid pace of investment in new healthcare facilities in these developing international markets provides a
significant opportunity for growth.
Expand  our  communication  solutions  in  non-healthcare  markets.         While  our  primary  focus  is  on  the  healthcare  market,  we  believe  that  our
communication solutions can also provide value in non-healthcare markets. Our communication solutions have been selected by over 270 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  System,  Vocera  Care  Experience  suite  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 System

The Vocera Communication 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 become part of the Vocera system. The system transforms
the way mobile workers communicate by enabling them to instantly connect via voice or text messaging 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.

Components of the Vocera Communication System include:

•

Vocera Communication Platform.     At the heart of our Vocera Communication System is a patent-protected, enterprise-class software platform that runs on
our customers' Windows-based servers. 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

5

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

and  management  functionality,  reporting  and  analytics  tools,  clinical  directories  and  user  profiles.  In  addition,  the  platform  contains  our  robust  workflow
capability  that  enables  customization  of  workflow  patterns  for  each  customer.  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 Communication Badge .     Our communication badge is a wearable device weighing less than two ounces that operates over customers’ industry-
standard Wi-Fi networks. The badge is worn clipped to a shirt or on a lanyard. It can be used to conduct hands-free communication and is the only hands-free
device  of  its kind. It  enables  instant  two-way  voice  conversations  without  the need to  remember  a phone  number  or use  a handset.  An over-the-air  update
mechanism  seamlessly  updates  device  software.  Our  badge  also  incorporates  automatic  diagnostic  mechanisms  that  feed  data  on  wireless  network
performance back to the software platform for reporting and diagnosis of problems. The Vocera B3000n badge, our fifth generation communication badge,
builds  upon  the  improved  durability,  louder  speaker  for  noisy  environments  and  proprietary  acoustic  noise  reduction  technology  of  the  fourth  generation
B3000 badge, and adds new wireless capability by supporting the IEEE 802.11n wireless standard. In April 2014 the Vocera B3000 communication badge
received FIPS 140-2 certification from the National Institute of Standards and Technology, and we are in the process of applying for these certifications for the
B3000n.  In  January  2015,  we  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 Collaboration Suite. The Vocera Collaboration Suite provides 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, the Vocera Collaboration Suite supports both personal (BYOD) and shared device usage models. The
Collaboration Suite includes both 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, and send
through a web-based console, or through integrated third-party clinical systems. Our software platform provides a highly reliable push messaging mechanism
as well as centralized routing intelligence, a directory of clinical users and contacts and the monitoring controls that display a real-time dashboard of delivery
and receipt confirmations and responses.

Vocera  Secure  Texting.  Launched  in  mid-2015,  Vocera  Secure  Texting  is  an  easy  to  use  alternative  to  non-secure  SMS  texting  that  enables  HIPAA-
compliance and includes our cloud-based Secure Texting application, extending the power of the Vocera Communication Platform to physicians and care
teams  that  are  located  both  inside  and  outside  the  hospital.  Vocera  Secure  Texting  balances  security  and  convenience  by  providing  an  easy-to-use,
HIPAA-compliant alternative to non-secure SMS texting and includes basic voice capabilities to enhance communication and collaboration. The solution
integrates  seamlessly  with the Vocera  Communication  Platform  , providing  texting  and voice  capabilities  across  a  wide  range  of  end  points  including
iPhone  and  Android  devices  and  all  popular  browsers.  Vocera  Secure  Texting  is  available  at  no additional  cost  to  existing  Vocera  customers  who are
current with their software maintenance contract.

Clinical Integration. Our platform has the ability to integrate with a diverse set of standards-based and customized adapters to a variety of telephony, clinical
and  EHR  systems.  We  can  integrate  and  manage  workflows  with  over  70  third-party  clinical  systems,  including  nurse  call,  patient  monitoring  and  EHR
systems. Our integration platform provides the content, context and workflow that enable the immediate delivery of interactive alerts and contextually relevant
data to hospital workers, helping to improve patient safety and satisfaction. For some integrations, customers can use the Vocera Clinical Workflow Engine to
integrate with these clinical systems and reduce the need for additional middleware, by enabling the Vocera Communication Platform to connect with a variety
of nurse call and patient monitoring systems. For example, as a result of our acquisition of mVisum, Inc., in 2014 we offer an FDA cleared solution that acts as
a secondary alarm notification system and provides clinical context, including waveforms, like EKGs and vital signs, providing decision support and insight
into the criticality of each alarm. The integration uses patented push notification technology to connect with and distribute data from many hospital alarm-
generating devices and deliver alarms and patient details to physicians and specialists on their smartphones. Configurable dashboards allow users to monitor
alarms  and alarm  responses at  the floor, nurse and individual  bed levels. Our Clinical  Analytics module  works in conjunction  with the Vocera  system and
provides  hospitals  with  the  evidence  needed  to  manage  and  improve  their  alarm  management  strategy  with  the  goal  of  reducing  alarm  fatigue,  improving
patient safety, and enhancing care team efficiency.

Choice  of  Devices.  In  July  2015,  we  announced  that  we  will  resell  Zebra  Technologies  MC40-HC  Android  mobile  computer  (MC40).  The  MC40  will  be
offered as a bundled solution with the Vocera Collaboration Suite to provide a complete, turnkey solution for our customers’ clinical communication needs.
We also work closely with Apple Inc. to offer a bundled solution that delivers our solution on iOS devices. This gives our customers a choice of different
devices to access the power of the Vocera Communications platform, including both iOS and Android devices.

Sales and marketing

Sales

Our sales employees call on hospitals and healthcare systems in the United States, the United Kingdom, Australia, New Zealand, Singapore, Malaysia and several
countries in the Middle East. As of December 31, 2015, we had 126 sales and account support employees. The sales team is organized to allow us to better serve
our  customers  and  to  support  the  different  elements  of  our  sales  strategy.  Certain  members  of  the  sales  team  focus  on  the  development  of  new  customer
relationships with large integrated health systems and government healthcare facilities. Our compensation is structured to incentivize new account development.
We  supplement  our  sales  organization  by  utilizing  a  U.S.  government-authorized  reseller  to  facilitate  our  sales  to  Veterans  Administration  and  Department  of
Defense healthcare facilities. Sales team members also focus on new customer development with smaller systems and individual hospitals. The sales team further
includes account managers who focus on service and additional sales to existing customers. We enhance our sales efforts by including in our sales staff individuals
with nursing backgrounds to address clinical uses with, and provide utilization advice to, customers and potential customers. We have also staffed our sales team
with system engineers who focus on the technical elements of system optimization, particularly wireless, and overall product configuration. We have a small direct
sales team to focus on developing our non-healthcare business, including hospitality, energy and other mission critical mobile work environments.

We strive to hire sales employees with at least 10 years of experience selling enterprise solutions in healthcare and who have experience selling in competitive and
complex environments with multiple decision makers. In markets outside the United States, our sales efforts are supplemented by a select group of resellers and
distributors.

Marketing

Our marketing efforts focus on building awareness and generating demand. We believe 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, 2015, we had  24 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  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 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  customers  include  over  1,150  hospitals  and  other  healthcare  facilities,  of  which  over  170  are  outside  of  the  United  States.  In  addition,  our  Vocera
Communication  solution  has  been  selected  by  over  270 facilities  in  other  non-healthcare  markets.  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. Our diverse customer base has very low customer revenue concentration.

During 2015 and 2014 , non-U.S. markets represented approximately 8.8% and 9.9% 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 on a combination of dedicated, proprietary
devices, as well as third-party smartphones and other devices.

8

Table of Contents

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. 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  solution.  The  market  for  in-building  wireless  phones  is  dominated  by  large  communications  companies  such  as  Cisco  Systems,  Ascom  and
Spectralink.

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  Collaboration  Suite  smartphone  apps,  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
product performance and reliability
the initial cost and ongoing cost of ownership
customer service and support capabilities

We may face increased competition in the future, including competition from large, multinational companies 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.

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; Knoxville, Tennessee; Toronto, Canada and Bangalore, India. There were 88 full-time research and development employees as
of December  31, 2015  .  We  also  utilized  small  teams  of  contractors  in  India  and  Ukraine  to  assist  with  quality  assurance  testing  and  automation,  and  targeted
development efforts. Our research and development expenditures were $17.0 million , $18.0 million and $14.9 million in 2015 , 2014 and 2013 , respectively.

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 29 U.S. patents as of December 31, 2015, including patents on many capabilities of our software platform and communication badge.  The expiration
dates of these patents range from 2018 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, France, the United Kingdom and the 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  device  products  to  original  design  manufacturers  and  contract  manufacturer,  SMTC  Corporation  (SMTC).  Our
communication badge is currently built in Mexico using custom tools and test equipment owned by us. Initial volumes of new products may be manufactured by
our contract manufacturer in U.S. facilities. Most of our accessories, including batteries, chargers and attachments, are built by original design manufacturers in
Asia.

9

 
Table of Contents

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.

In July 2015, we announced that Vocera will resell Zebra Technologies MC40-HC Android mobile computer (MC40). The MC40 will be offered as a bundled
solution with the Vocera Collaboration Suite to provide a complete, turnkey solution for our customers’ clinical communication needs.

Employees

As of December 31, 2015 , we had 387 employees, consisting of 18 in manufacturing and quality operations, 88 in research and development, 150 in sales and
marketing, 88 in services and 43 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 $58.2 million and $33.1 million at December 31, 2015 and 2014 , respectively. Of the current backlog, all but $28.7 million
is expected to be delivered in 2016.

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. Healthcare reform has been recently enacted at the federal level. We expect federal and state legislatures and agencies to continue to consider 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.  Similarly,  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 customer, and damage to our brand and reputation. We endeavor to mitigate these
risks through measures we believe

10

Table of Contents

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 devices 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  our  products.  In  this  event,  we  would  be  subject  to  extensive
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 or premarket approval of our products from the FDA prior to commercial distribution. Some
of  the  new  products  acquired  as  a  result  of  the  mVisum  acquisition  are  regulated  by  the  FDA  as  Class  II  medical  devices  under  applicable  law  and  FDA
regulations,  including  being  subject  to  the  2.3%  excise  tax  that  was  in  effect  under  the  Affordable  Care  Act  through  December  31,  2015.  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, for other products we could become subject to the 2.3% excise tax 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 $17.1 million for the year ended December 31, 2015. As of December 31, 2015 , we had
an accumulated deficit of $109.8 million . If we cannot achieve profitability in future periods, our business and our stock price may be adversely affected.

12

 
Table of Contents

Our  ability  to  be  profitable  in  the  future  depends  upon  continued  demand  for  our  communication  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 patient safety and satisfaction and
increase  hospital  efficiency  and  productivity,  and  to  bring  value  to  customers  outside  of  healthcare.  Additionally,  further  adoption  of  our  solutions  in  non-
healthcare  markets  depends  on  our  ability  to  modify  our  products  to  successfully  respond  to  the  challenges  in  those  markets  and  our  sales  efforts  to  reach  the
customers in those markets. 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  of  our  Vocera  Communication  solution  in  the  healthcare  market  for  substantially  all  of  our  revenue,  and  decrease  in  sales  in  the
healthcare market would harm our business.

To date, substantially all of our revenue has been derived from sales of our Vocera Communication solution to the healthcare market and, in particular, hospitals.
Sales of our Vocera Communication solution to the healthcare market accounted for 94%, 90% and 91% of our revenue for the year ended December 31, 2015 ,
December 31, 2014 and 2013, respectively. We anticipate that sales of our Vocera Communication solution will represent a significant portion of our revenue for
the foreseeable future.

We obtain a significant portion of our sales from existing hospital customers. While we are seeking to sell our Vocera Communications solution to non-healthcare
customers, we do not anticipate that sales of our Vocera Communication solution in non-healthcare markets will represent a significant portion of our revenue for
the foreseeable future.

Our success depends in part upon the deployment of our Vocera Communication solution by new hospital customers, the expansion and upgrade of our solution at
existing  customers,  and  our  ability  to  continue  to  provide  on  a  timely  basis  cost-effective  solutions  that  meet  the  requirements  of  our  hospital  customers.  Our
Vocera Communication solution requires a substantial upfront investment by customers. Typically, our hospital customers initially deploy our solution for specific
users in specific departments before expanding our solution into other departments or for other users. 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 infrastructure, if any, within the hospital.

Even  if  hospital  personnel  determine  that  our  Vocera  Communication  solution  provides  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
solution or expand our solution to other departments or users. Hospitals are currently facing 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 penalties from the implementation of the Patient Protection and Affordable
Care Act of 2010 (ACA) and other healthcare reform legislation. As a consequence, we may experience slowdowns and deferral of orders for our solution that
could  negatively  impact  our  sales.  We  might  not  be  able  to  sustain  or  increase  our  revenue  from  sales  of  our  Vocera  Communication  solution,  or  achieve  the
growth rates that we envision, if hospitals continue to face significant budgetary constraints and reduce their spending on communications systems.

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 Vocera Communication or Care Experience 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, 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 solution. 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.

13

Table of Contents

As we continue to pursue opportunities for larger deals, we may experience a longer time period for the deals 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 of nine to twelve months or more. We spend substantial time, effort and money in our sales efforts without any assurance that our
efforts will produce sales. In addition, purchases of our solutions are frequently subject to budget constraints, multiple approvals, and unplanned administrative,
processing and other delays. For example, we experienced elongated sales cycles due to uncertainty surrounding healthcare reform and lower hospital admission
trends in 2013 and 2014. At this time, hospitals in the U.S. face significant uncertainty over the continuing impact of federal government budgets, and continuing
changes  in  the  implementation  and  deadlines  for  compliance  with  the  ACA  and  other  healthcare  reform  legislation,  as  well  as  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  fluctuation  has  placed,  and  may
continue to place, strains on our management systems, infrastructure and other resources. Especially during growth periods, we may plan to hire additional direct
sales 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 at all. 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 result in 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;
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;
the announcement of new significant contracts or relationships;
the procurement and deployment cycles of our healthcare customers and the length of our sales cycles;

variations in the amount of orders booked in a prior quarter but not delivered until later quarters;
our mix of solutions and pricing, including discounts by us or our competitors;
our ability to expand into non-healthcare markets;
our ability to develop significant new reseller relationships;
our ability to forecast demand and manage lead times for the manufacture of our solutions; and
our ability to develop and introduce new solutions and features to existing solutions that achieve market acceptance.

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 profit margins of our hospital customers are modest, and pending changes 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 drive substantive changes over several years to the operating processes, reimbursements and
rules governing the U.S. healthcare system. The actual end effect of these laws on the marketplace is not yet fully understood.

We believe that our healthcare customers are unsure of the impact that a number of the elements of those acts 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,  have  challenged  hospitals’
abilities to forecast patient utilization and revenues, and to set operational plans and budget accordingly.

Federal  budget  activities  also  impact  our  customers.  We  believe  that  it  is  likely  that  additional  legislative  changes  by  Congress  and  rulemaking  by  HHS  will
continue. Our customers include healthcare facilities run by the Department of Defense and the U.S. Department of Veterans Affairs. These potential customers
have been and may continue to be impacted by budgetary and legislative actions.

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  at  this  time  the  primary  competition  for  our  Vocera  Communication  solution  consists  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 solution requires 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
attempt  to  sell  their  products  to  hospitals  as  components  of  an  overall  communication  system.  Of  these  product  categories,  in-building  wireless  telephones
represent  the most significant  competition  for the sale of our solution. The market  for in-building wireless phones is dominated  by communications  companies
such as Cisco Systems, Ascom and

15

Table of Contents

Spectralink. In addition, the proliferation of smartphones and related applications, including cloud-based applications, may represent a new category of competitive
offerings. While we consider secured text-messaging using smartphones a feature valued by many customers, we do not believe most of our potential customers
would consider that feature alone an adequate substitute for a voice communication solution. However, some customers may choose free text-messaging solutions
even if not HIPAA-compliant, given their budget constraints.

While we do not have a directly comparable competitor that provides a solution as richly-featured as the Vocera Communication system 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 may have existing relationships within the hospital,
which may enhance their ability to gain a foothold in our market. 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.

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 Vocera Communication solution, 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  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 upon a contract manufacturer 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 a  contract  manufacturer,  SMTC,  to  produce  the  primary  hardware  component  of  our  Vocera
Communication solution. We have entered into a manufacturing agreement with SMTC that is terminable by either party with advance notice and that may also be
terminated  for  a  material  uncured  breach.  We  also  rely  on  original  design  manufacturers,  or  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  SMTC  or  an  ODM  is  unable  or  unwilling  to  continue  manufacturing
components  of our solutions in the  volumes 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.

SMTC or ODMs may experience problems that could impact the quantity and quality of components of our Vocera Communication solution, including disruptions
in their manufacturing operations due to equipment breakdowns, labor strikes or shortages, component or material shortages and cost increases. SMTC 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  components  of  our
Vocera Communication 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.

Companies  occasionally  encounter  unexpected  difficulties  in  ramping  up  production  of  new  products,  and  we  may  experience  such  difficulties  with  future
generations of our products. SMTC and our ODMs also manufacture products for other companies. Generally, our orders represent a relatively small percentage of
the overall orders received by SMTC and these ODMs from their customers; therefore, fulfilling our orders may not be a priority in the event SMTC or an ODM is
constrained in its ability to fulfill all of its customer obligations. In addition, if SMTC 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.

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 manufacturer, SMTC, and we and SMTC 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 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 SMTC 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  Vocera
Communication solution, then they may experience technical problems or not purchase our solution at all.

The  effectiveness  of  our  Vocera  Communication  solution  depends  upon  the  quality  and  compatibility  of  the  communications  environment  that  our  healthcare
customers maintain. Our solutions require voice-grade wireless, or Wi-Fi, installed through large enterprise environments, which can vary from hospital to hospital
and from department to department within a hospital. Many

17

Table of Contents

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 Vocera Communication solution, 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  Vocera  Communication  solution  to  be  fully  functional.  The  additional  cost  of  installing  or  upgrading  a  Wi-Fi  network  may
dissuade  potential  customers  from  installing  our  solution.  Furthermore,  if  changes  to  a  customer's  physical  or  information  technology  environment  cause
integration  issues  or  degrade  the  effectiveness  of  our  solution,  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 solution 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 Vocera Communication solution, 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 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  the
Vocera communication solution incorporating the B2000 and B3000 badges. We are continuing to carry out further compliance activities. A failure on our part to
achieve and maintain compliance, both as to current products and as to new product versions, could adversely impact our revenue.

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  customer  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  and  divert  attention  of  management  and  key  information
technology resources.

Our efforts to sell our communications 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
Vocera Communication solution has been deployed in over 250 customers in non-healthcare markets. Total revenue from non-healthcare customers accounted for
2% of our revenue for the year ended December 31, 2015 and 3% for each of the years ended December 31, 2014 and 2013. If we cannot maintain these customers
by providing communications solutions that meet their requirements, if we cannot successfully expand our communications solutions in non-healthcare markets, or
if adoption of our solutions is 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  communications
solutions also may not contain the functionality required by these non-healthcare markets or may not sufficiently differentiate us from competing solutions such
that customers can justify deploying our solutions.

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

18

Table of Contents

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  may  experience  technical  problems  and
additional  costs  as  we  introduce  new  features  to  our  software  platform,  deploy  future  models  of  our  wireless  badges,  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  Vocera  Communication
solution. 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  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,  such as our  acquisitions  of
mVisum in the first quarter of 2014 and Prana Technologies in the third quarter of 2014. 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 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 communications 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 the 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; and
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.

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.  If  we  were  to  proceed  with  one  or  more  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.

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  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 37% , 37% and 31%
of our revenue for the year ended December 31, 2015 , December 31, 2014 and 2013, 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 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 year ended December 31, 2015 , December 31, 2014 and 2013, we generated 8.8% , 9.9% and 10.5% of
our  revenue,  respectively,  from  customers  outside  of  the  United  States,  including  Canada,  the  United  Kingdom,  Australia,  the  Republic  of  Ireland  and  New
Zealand. In the second quarter of 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;
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. If we cannot successfully integrate our solution with these vendors as needed or if any hardware or software of these
vendors contains any defect or error, then our solution may not perform as designed, or may exhibit a defect or error.

Any defects or errors in, or which are attributed to, our solutions, 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; 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 communications business, we handle and have access to personal health information subject in the United States to 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  EU  adopted  the  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. Similarly, 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 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 recently 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 badges and related hardware accessories 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 plan to
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-

21

Table of Contents

house, which will expose us to the creditworthiness of such equipment 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.

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. We believe that
companies have been 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. In addition, our customers could further 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

22

Table of Contents

brought against us by third parties. Further, litigation may involve patent holding companies or other adverse patent owners who have no relevant products and
against whom our potential patents may provide little or no deterrence.

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. It is possible that 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-

23

Table of Contents

compliance,  or  any  regulatory  developments,  could  negatively  impact  the  sales  of  our  solutions,  require  costly  modifications  to  our  solutions,  and  harm  our
reputation.

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.

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 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. 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. 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. A clinical communications product acquired from mVisum is regulated by the FDA as a Class II medical device.

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.

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  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, 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.

As  an  “emerging  growth  company”  under  the  JOBS  Act,  we  are  permitted  to,  and  may,  rely  on  exemptions  from  certain  disclosure  and  governance
requirements.

As an “emerging growth company” under the Jumpstart Our Business Startups Act (JOBS Act), we are permitted to, and may, rely on exemptions from certain
disclosure  and  governance  requirements.  For  example,  for  so  long  as  we  are  an  emerging  growth  company,  which  can  last,  at  most,  until  the  first  fiscal  year
following the fifth anniversary of our initial public offering, we will not be required to:
•

have  our  independent  registered  public  accounting  firm  report  on  our  internal  control  over  financial  reporting  pursuant  to  Section  404(b)  of  the  Sarbanes-
Oxley Act of 2002 (Sarbanes-Oxley Act);
comply  with  any  requirement  that  may  be  adopted  by  the  Public  Company  Accounting  Oversight  Board  regarding  mandatory  audit  firm  rotation  or  a
supplement to the auditor's report providing additional information about the audit and the financial statements;
provide  the  “compensation  discussion  and  analysis”  and  certain  compensation  tables  for  our  named  executive  officers  in  our  Form  10-K  or  annual  proxy
statement; and
submit certain executive compensation matters to stockholder advisory votes, such as “say on pay” and “say on frequency.”

•

•

We could be an emerging growth company until the first fiscal year following the fifth anniversary of our initial public offering. However, if the market value of
our common stock that is held by non-affiliates exceeds $700 million as of June 30th of any year, we could cease to be an “emerging growth company” as of the
following December 31st. This threshold was not reached for June 30, 2015. After exceeding the threshold, as of each fiscal year end, our independent registered
public accounting firm will be required to evaluate and report on our internal control over financial reporting under Section 404(b) of the Sarbanes-Oxley Act.
While management has established plans to accommodate the additional assessment and attestation procedures and related costs of Section 404(b) compliance, we
may incur additional costs or require additional management time to comply with Section 404(b) in a timely manner.

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.

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 (once
such  opinion  is  required  under  the  Sarbanes-Oxley  Act),  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, even though we as an “emerging growth company” may rely upon the disclosure
and  governance  exemptions  under  the  JOBS  Act.  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 are currently, 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 is pending in the United States District Court for the Northern
District  of  California  against  us  and  certain  of  our  officers  and  directors.  The  suit  purports  to  allege  claims  for  allegedly  misleading  statements  regarding  our
business and financial results. 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 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;
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 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;
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 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.

From time to time, we 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.

Securities Litigation

On August 1 and 21, 2013, two putative securities class action suits were filed in the United States District Court for the Northern District of California against us
and  certain  of  our  officers,  our  board  of  directors,  a  former  director  and  the  underwriters  for  the  initial  public  offering.    On  November  20,  2013,  the  court
consolidated  the  actions  as  In  re  Vocera  Communications,  Inc.  Securities  Litigation  and  appointed  Lead  Plaintiffs.    Lead  Plaintiffs  filed  their  consolidated
complaint on September 19, 2014.   The consolidated complaint names certain current and former officers and directors and the underwriters for our initial public
offering and secondary offering and alleges claims under Sections 11, 12(a)(2) and 15 of the Securities Act of 1933, as amended (Securities Act) and Section 10(b)
and  20(a)  of  the  Exchange  Act  based  on  allegedly  false  and  materially  misleading  statements  and  omissions  in  the  registration  statement  for  our  initial  public
offering and secondary offering and in communications regarding its business and financial results. The suit is purportedly brought on behalf of purchasers of our
securities between March 28, 2012 and May 2, 2013, and seeks compensatory damages, rescission, fees and costs, as well as other relief.  On November 3, 2014,
Defendants moved to dismiss the consolidated complaint. On February 11, 2015, the Court granted Defendants' motion to dismiss the Securities Act claims, but
denied the motion as to the Exchange Act claims, allowing the matter to proceed on that basis. On April 27, 2015, Defendants filed answers to the consolidated
complaint.

In connection with a mediation, an agreement in principle to settle the suit was reached in October 2015. On March 4, 2016, the Court issued an order granting
Lead Plaintiffs' motion for preliminary approval of the settlement. The settlement, which is subject final approval of the Court, calls for payment of $9 million,
which will be funded entirely by our insurance carriers.

Due to the inherent uncertainties of litigation, we cannot accurately predict the ultimate outcome of this matter. We are unable at this time to determine whether the
outcome of the litigation would have a material impact on our results of operations, financial condition or cash flow. We have not established any reserve for any
potential liability relating to this lawsuit.

As of March 11, 2016 , we had 65 holders of record of our common stock. The actual number of stockholders is greater than this number of record holders, and
includes stockholders who are beneficial owners, but whose shares are held in street name by brokers and other nominees. This number of holders of record also
does not include stockholders whose shares may be held in trust by other entities.

Dividend policy

We have never declared or paid any cash dividends on our capital stock, and we do not currently intend to pay any cash dividends on our common stock for the
foreseeable future. We expect to retain future earnings, if any, to fund the development and growth of our business. Any future determination to pay dividends on
our common stock will be at the discretion of our board of directors and will depend upon, among other factors, our financial condition, operating results, current
and anticipated cash needs, plans for expansion and other factors that our board of directors may deem relevant.

Stock Performance

This stock performance graph shall not be deemed “soliciting material” or to be “filed” with the SEC for purposes of Section 18 of the Exchange Act, or otherwise
subject to the liabilities  under that Section, and shall not be deemed to be incorporated by reference into any filing of Vocera Communications, Inc. under the
Securities Act or the Exchange Act.

The following stock performance graph compares the cumulative total return provided to holders of the common stock of Vocera Communications, Inc. relative to

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 improve patient safety and experience, and increase operational efficiency. As of December 31, 2015, our
solutions have been selected by more than 1,400 facilities worldwide.

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  manufacturer,  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 sales and unanticipated shifts in sales volume and mix.

We primarily sell products, software maintenance and professional services directly to end users. Total revenue increased 9.1% to $104.1 million in 2015 from
$95.4 million in 2014 , and our 2014 revenue decreased 6.9% from $102.5 million in 2013 . For the year ended December 31, 2015 , we recorded a net loss of
$17.1 million compared to a net loss of $28.3 million for the year ended December 31, 2014 .

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,  Singapore  and  parts  of  the  Middle  East,  most  of  our  customers  are  located  in  the  United  States.  International
customers  represented  8.8% and 9.9% of  our  revenue  in  2015 and  in  2014 ,  respectively.  We  are  developing  plans  to  expand  our  presence  in  other  English-
speaking markets and enter non-English speaking markets.

In  recent  years,  U.S.  hospital  spending  on  information  technology  has  been  predominantly  directed  toward  further  investment  in  electronic  health  records  and
preparation for utilizing new ICD-10 diagnosis coding, which are both driven by regulatory requirements and reimbursement  earn-back incentives from federal
healthcare  reform.  In  addition,  as  patient  volumes  and  reimbursement  levels  continued  to  fluctuate  for  many  healthcare  providers,  hospitals  exercised  strong
expense  limits  and  reductions,  also  impacting  capital  purchases  and  departmental  operating  budgets  through  which  our  solutions  are  purchased.  However,  we
believe that healthcare providers are placing increased emphasis on and investment in solutions for communication and care coordination, a trend that we believe is
favorable for Vocera.

We believe certain international markets represent attractive opportunities for growth. We currently sell our solutions in Canada, the United Kingdom as well as
multiple English speaking countries in the Asia-Pacific and Middle East regions where we see significant investment in healthcare systems to improve capacity and
quality.

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 and deferred revenue” 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.  Software
revenue is derived primarily from the sale of perpetual licenses to our Vocera Communication System. We derive additional software revenue from the sale of
term licenses and hosted software

32

 
Table of Contents

•

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. Sales commissions are earned when an order is received from a customer, and as a result, in
some cases these commissions are expensed in an earlier period than the period in which the related revenue is recognized. Historically, our bookings have
tended to peak in the fourth quarter of each year, driving higher sales commissions, and to be lowest in the first quarter. We intend to continue to expand our
direct sales force and invest in sales support functions and new marketing programs for the foreseeable future.
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.
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, 2015 , we held a $36.0 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  $8.7 million , or 9.1% , for  the  year  ended  December  31, 2015 compared  to  the  year  ended  December  31,  2014. The  increase  in  total
revenue was a result of increases in both product and services revenue.

Product  revenue  increased  $4.6  million  ,  or  9.0% ,  for  the  year  ended  December  31,  2015  compared  to  the  year  ended  December  31,  2014.  Device  revenue
increased $3.1 million , or 8.3% , and software revenue increased $1.5 million , or 11.2% , for the year ended December 31, 2015, compared to the year ended
December 31, 2014. The increase in device revenue, which related entirely to our Communication solution, was driven primarily by an increase 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 Communication software.

Service revenue increased $4.0 million , or 9.1% , for the year ended December 31, 2015 compared to the year ended December 31, 2014. Software maintenance
and  support  revenue  increased  $3.1  million  ,  or  8.7% ,  and  professional  services  and  training  revenue  increased  $1.0  million  ,  or  10.6% ,  for  the  year  ended
December 31, 2015 compared to the year ended December 31, 2014. The increase in software maintenance and support revenue was primarily a result of having a
larger  customer  base.  The  increase  in  professional  services  and  training  revenue  was  due  to  the  increases  in  implementation  services  for  our  Communication
solution.

Cost of product revenue increased $0.9 million , or 4.8% , for the year ended December 31, 2015 compared to the year ended December 31, 2014. The cost of
product  revenue  increased  primarily  due  to  a  higher  number  of  communication  badges  and  related  accessories  sold.  Product  gross  margin  as  a  percentage  of
product revenue increased in the year ended December 31, 2015 compared to the year ended December 31, 2014 due to higher absorption of fixed overhead costs.

Cost of service revenue increased $1.4 million , or 7.4% , for the year ended December 31, 2015 compared to the year ended December 31, 2014. The cost of
service  revenue  increased  primarily  due  to  an  increase  in  the  number  of  deployments  of  our  Communication  solution.  Service  gross  margin  as  a  percentage  of
service revenue increased for the year ended December 31, 2015 compared to the year ended December 31, 2014 due to higher absorption of our fixed overhead
costs and improved resource utilization rates.

Research and development expense . Research and development expense decreased $1.0 million , or 5.8% , for the year ended December 31, 2015 compared to the
year ended December 31, 2014. This decrease was primarily due to a $1.1 million decrease in outside services. This decrease was partially offset by an increase of
$0.1 million in equipment supplies.

Sales and marketing expense. Sales and marketing expense decreased $2.0 million , or 4.0% , for the year ended December 31, 2015 compared to the year ended
December 31, 2014. This was primarily due to a $0.6 million decrease in personnel and travel costs associated with lower compensation and timing of hiring as
well as a $1.6 million decrease in outside services and marketing programs. This decrease was partially offset by a $0.2 million increase in equipment and supplies.

General and administrative expense. General and administrative expense decreased $1.3 million , or 7.4% , from the year ended December 31, 2015 compared to
the year ended December 31, 2014. This resulted primarily from a decrease of $0.4 million in outside services related to lower legal expenses and a lower reliance
on consultants.

Restructuring  expense.  Restructuring  expense  decreased  $0.6  million  for  the  year  ended  December  31,  2015  compared  to  the  year  ended  December  31,  2014.
During the fourth quarter of 2014, we initiated a restructuring plan that resulted in $0.7 million of severance charges, of which $0.1 million was recorded to cost of
revenue and $0.6 million was recorded to operating expenses. See Note 6, Consolidated balance sheet components , in the Notes to the Consolidated Financial
Statements in Item 8 of this Report, for further discussion of our restructuring activities.

Interest income. Interest income increased $0.2 million for the year ended December 31, 2015 compared to the year ended December 31, 2014 due to the shift in
these periods from cash equivalents to higher interest-bearing short-term investments.

Other expense, net. The change in other expense, net for the year ended December 31, 2015 compared to the year ended December 31, 2014 was primarily due to
foreign exchange fluctuations.

Provision for income taxes. The $0.5 million provision on $16.6 million of loss before income taxes in 2015 represented a negative effective tax rate of 2.8% . The
negative effective tax rate for 2015 was due primarily to the impact of pre-tax losses in the U.S. operations, offset by income taxes from foreign operations. The
negative effective tax rate of 1.2% in 2014 is due primarily to the impact of pre-tax losses in the U.S. operations, offset by income taxes from foreign operations.

Total  revenue  decreased  $7.1  million,  or  6.9%,  for  the  year  ended  December  31,  2014  compared  to  the  year  ended  December  31,  2013.  The  decrease  in  total
revenue was primarily a result of an $11.3 million decrease in product revenue, partially offset by a $4.2 million increase in service revenue.

Product  revenue  decreased  $11.3  million,  or  18.1%,  for  the  year  ended  December  31,  2014  compared  to  the  year  ended  December  31,  2013.  Device  revenue
decreased  $9.2  million,  or  19.7%,  and  software  revenue  decreased  $2.1  million,  or  13.4%  for  the  year  ended  December  31,  2014  compared  to  the  year  ended
December 31, 2013. The decrease in device revenue, which related entirely to our Voice Communication solution, was driven primarily by a decrease in unit sales
of badges and related accessories. We believe that our product revenue for the year ended December 31, 2014 was adversely affected by the conditions affecting
the U.S. healthcare industry as described above. The decrease in software revenue was mainly a result of a decrease in sales of Voice Communication software
licenses.

Service revenue increased $4.2 million, or 10.5%, for the year ended December 31, 2014 compared to the year ended December 31, 2013. Software maintenance
and support revenue increased $3.8 million, or 12.0%, and professional services and training revenue increased minimally, for the year ended December 31, 2014
compared to the year ended December 31, 2013. The increase in software maintenance and support revenue was primarily a result of having a larger customer base
purchasing our maintenance and extended warranty offerings which increased software maintenance revenue by $2.8 million and extended warranty revenue by
$1.0  million.  Professional  services  and  training  revenue  increased  $0.4  million,  or  5%,  for  the  year  ended  December  31,  2014  compared  to  the  year  ended
December 31, 2013. This increase was due to an increase in the total number of deployments in 2014, primarily related to our existing customer base.

Cost of product revenue decreased $2.9 million, or 13.6%, for the year ended December 31, 2014 compared to the year ended December 31, 2013. The cost of
product  revenue  decreased  primarily  due  to  a  decrease  in  the  number  of  units  of  communication  badges  and  related  accessories  sold,  lower  standard  warranty
expense, partially offset by higher overhead costs.

Cost of service revenue increased $1.9 million, or 11.3%, for the year ended December 31, 2014 compared to the year ended December 31, 2013. This increase
was primarily due to a $1.4 million increase in employee wages and other personnel costs and a $0.3 million increase in travel related expenses in our services
organization to support growth in customer deployments and technical support. Extended warranty expenses increased $0.2 million due to an increase in badges
under the extended warranty program and related warranty claims.

Research and development expense . Research and development expense increased $3.1 million, or 20.9%, for the year ended December 31, 2014 compared to the
year  ended  December  31,  2013.  This  increase  was  primarily  due  to  a  $2.2  million  increase  in  personnel  costs  and  other  expenses  associated  with  increases  in
headcount, including acquisitions, a $0.5 million increase due to additional external resources for research and development projects, a $0.2 million increase in
materials for research and development projects and a $0.2 million increase in stock-based compensation.

Sales and marketing expense. Sales and marketing expense increased $4.7 million, or 10.4%, for the year ended December 31, 2014 compared to the year ended
December  31,  2013.  This  increase  was  primarily  due  to  a  $2.7  million  in  increased  employee  wages,  commissions  and  personnel  costs  and  $1.2  million  in
increased stock-based compensation.

General and administrative expense. General and administrative expense increased $3.2 million, or 21.2%, from the year ended December 31, 2014 compared to
the year ended December 31, 2013. This increase was due primarily to an increase of $1.2 million in personnel costs, an increase of $0.8 million in stock-based
compensation, an increase of $0.4 million in legal expenses primarily related to litigation, an increase of $0.3 million in depreciation associated with the SAP ERP
deployment, an increase of $0.2 million in facilities-related expenses and an increase of $0.1 million in business insurance.

Restructuring  expense.  Restructuring  expense  increased  $0.6  million  for  the  year  ended  December  31,  2014  compared  to  the  year  ended  December  31,  2013.
During the fourth quarter of 2014, we initiated a restructuring plan that resulted in $0.7 million of severance charges, of which $0.1 million was recorded to cost of

Provision for income taxes. The $0.3 million provision on $28.0 million of loss before income taxes in 2014 represented a negative effective tax rate of 1.2%. The
negative effective tax rate for 2014 was due primarily to the impact of pre-tax losses in the U.S. operations, offset by income taxes from foreign operations. The

As of December 31, 2015 , we had cash and cash equivalents and short-term investments of $116.8 million and no debt.

During 2015 , 2014 and 2013 , our purchases of property and equipment were $1.2 million, $2.0 million and $3.8 million, respectively. The expenditures in 2015
primarily  relate  to  leasehold  improvements  and  computer  equipment.  The  expenditures  in  2014  primarily  relate  to  leasehold  improvements  and  computer
equipment. The expenditures in 2013 included completion of the first phase of our ERP implementation in August 2013 and build out of additional leased space
available in April 2013.

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 used by operating activities was $0.1 million in 2015, due in part to the 2015 net loss of $17.1 million , partially offset by non-cash items such as depreciation
and  amortization  of  $3.3  million  for  property  and  equipment  and  acquired  intangible  assets  and  stock-based  compensation  of  $11.0  million.  With  respect  to
changes in assets and liabilities, cash was provided through a decrease of $0.6 million in inventory, a $1.1 million increase in accounts payable, a $2.8 million
increase in accrued liabilities and a $4.1 million increase in deferred revenue. These factors were offset by certain cash outflows, including an increase in accounts
receivable of $5.1 million, which is attributable to current period's billings exceeding collection on prior periods' invoices, and $0.3 million increase in prepaid
expenses.

Cash used by operating activities was $4.7 million in 2014, due in part to the 2014 net loss of $28.3 million, partially offset by non-cash items such as depreciation
and  amortization  of  $3.0  million  for  property  and  equipment  and  acquired  intangible  assets  and  stock-based  compensation  of  $11.1  million.  With  respect  to
changes  in  assets  and  liabilities,  cash  was  provided  by  a  decrease  in  accounts  receivable  of  $5.7  million,  which  is  attributable  to  collection  on  prior  periods'
invoices exceeding the current period's billings, a decrease of $1.9 million in inventory, a $1.1 million increase in accrued liabilities and a $2.8 million increase in
deferred revenue. These factors were offset by certain cash outflows, including a $1.7 million decrease in accounts payable and $0.3 million increase in prepaid
expenses.

Cash  used  by  operating  activities  was  $1.3  million  in  2013,  due  in  part  to  the  2013  net  loss  of  $10.5  million,  together  with  inventory  growth  of  $3.0  million
attributable to downward revision of projections for our 2013 shipments which did not significantly reduce the lagged inventory receipt commitments until year-
end,  accounts  receivable  growth  of  $1.9  million,  and  decrease  in  accrued  and  other  liabilities  of  $1.9  million.  These  were  partially  offset  by  non-cash  items,
including stock-based compensation of $8.7 million and depreciation of property and equipment and intangibles amortization of $2.5 million. Additional offset was
provided by the increase in deferred revenues of $4.2 million and the increase of $0.7 million in accounts payable.

Investing activities

Cash used in investing activities was $3.8 million in 2015, which was primarily attributable to $109.3 million in purchases of short-term investments, partly offset
by  $106.7  million  short-term  investment  maturities.  An  additional  $1.2  million  of  cash  was  used  for  the  purchase  of  property  and  equipment  and  leasehold
improvements.

Cash  used  in  investing  activities  was  $14.4  million  in  2014,  which  was  primarily  attributable  to  $7.0  million  for  the  acquisitions  of  mVisum  and  Prana
Technologies, net of cash acquired, and $112.3 million for purchases of short-term investments, net of maturities received of $102.7 million and $3.9 million in
sales of short-term investment. An additional $2.0 million of cash was used for the purchase of property and equipment, partly offset by the release of $0.3 million
in restricted cash.

Cash used in investing activities was $56.7 million in 2013, which was primarily attributable to the purchase of short-term investments of $118.7 million, net of
maturities  received  of  $65.7  million,  plus  the  purchase  of  property  and  equipment  and  leasehold  improvements  of  $3.8  million.  The  short-term  investment
purchases primarily reflected our decision in early 2013 to migrate all investment and cash equivalents from our single asset manager into new portfolios, split
between two new asset managers. The maturities reflected the proceeds from the liquidation of the former asset manager's portfolio, as well as fairly short-term
maturities  on  the  new  portfolios,  leading  to  a  short-term  investments  balance  of  $88.0  million  as  of  December  31,  2013,  with  the  remainder  invested  in  cash
equivalents.

Financing activities    

Cash  provided  by  financing  activities  was  $1.8 million in  2015,  primarily  attributable  to  $1.2 million of  proceeds  from  stock  option  exercises,  $1.3 million of
proceeds from issuance of common stock from the employee stock purchase plan, $0.1 million of proceeds from common stock warrant exercises and $0.9 million
of cash from lease-related performance obligations. These items were partially offset by a $1.7 million decrease for employee taxes paid on net share settlement on
the vesting of restricted stock awards.

Cash provided  by financing  activities  was $2.1 million  in 2014, which was attributable  to employee  stock purchase plan proceeds  of $1.6 million,  exercises  of
stock  options  of  $1.1  million  and  cash  from  lease-related  performance  obligations  of  $0.6  million,  partially  offset  by  $1.2  million  of  taxes  paid  on  behalf  of
employees for net share settlement.     

Cash provided  by financing  activities  was $5.1 million  in 2013, which was attributable  to employee  stock purchase plan proceeds  of $3.0 million,  exercises  of
stock options of $1.8 million, cash from lease-related performance obligations of $0.8 million, exercise of common stock warrants of $0.2 million, partially offset
by $0.7 million of taxes paid on behalf of employees for net share settlement.

(1) Consists of contractual obligations from non-cancelable office space under operating leases.
(2) Consists of minimum purchase commitments with our independent contract manufacturer and other vendors.

As of December 31, 2015 , we had $0.5 million of net deferred tax liabilities and $0.2 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 10.

Off-balance sheet arrangements

During 2015 , 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

40

 
 
 
 
 
 
 
Table of Contents

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

We  derive  revenue  from  the  sales  of  communication  badges,  smartphones,  perpetual  software  licenses  for  software  that  is  essential  to  the  functionality  of  the
communication badges, software maintenance, extended warranty and professional services. We also derive revenue from the sale of licenses for software that is
not  essential  to  the  functionality  of  the  communication  badges,  which  may  include  Clinical  Integration  and  Vocera  Collaboration  Suite  as  well  as  certain
subscription-based revenues including Vocera Care Experience. Sales tax is excluded from reported total revenue.

Revenue is recognized when all of the below criteria are met:

•
•
•
•

there is persuasive evidence that an arrangement exists, in the form of a written contract, amendments to that contract, or purchase orders from a third party;
delivery has occurred or services have been rendered;
the price is fixed or determinable after evaluating the risk of concession; and
collectability is reasonably assured based on customer creditworthiness and past history of collection.

A  typical  sales  arrangement  involves  multiple  elements,  such  as  sales  of  communications  badges,  perpetual  software  licenses,  professional  services  and
maintenance services which entitle customers to unspecified upgrades, bug fixes, patch releases and telephone support. Revenue from the sale of communication
badges and perpetual software licenses is recognized upon shipment or delivery at the customers’ premises as the contractual provisions governing sales of these
products do not include any provisions regarding acceptance, performance or general right of return or cancellation or termination provisions adversely affecting
revenue recognition. Revenue from the sale of maintenance services on software licenses is recognized over the period during which the services are provided,
which is generally one year. Revenue from professional services is recognized either on a fixed fee basis based on milestones or on a time and materials basis as
the services are provided, both of which generally take place over a period of two to twelve weeks.

We  also  derive  revenue  from  the  provision  of  hosted  services  on  a  subscription  basis.  Revenue  from  these  products  is  recognized  ratably  over  the  term  of  the
arrangement.

In arrangements with multiple deliverables, assuming all other revenue criteria are met, we recognize revenue for individual delivered items if they have value to
the customer on a standalone basis. We allocate arrangement consideration at the inception of the arrangement to all deliverables using the relative selling price
method.  This  method  requires  us  to  determine  the  selling  price  at  which  each  deliverable  could  be  sold  if  it  were  sold  regularly  on  a  standalone  basis.  When
available, we use vendor-specific objective evidence (VSOE) of the selling price. VSOE represents the price charged for a deliverable when it is sold separately, or
for a deliverable not yet being sold separately, the price established by management with the relevant authority. We have established VSOE of the selling price for
our post-installation technical support services. When VSOE of selling price is not available, third-party evidence (TPE) of selling price for similar products and
services  is  acceptable;  however,  our  offerings  and  market  strategy  differ  from  those  of  our  competitors,  such  that  we  cannot  obtain  sufficient  comparable
information about third parties' prices. If neither VSOE nor TPE are available, we use our best estimates of selling prices (BESP). We determine BESP considering
factors such as market conditions, sales channels, internal costs and product margin objectives and pricing practices. We regularly review and update our VSOE
and BESP information.

The relative selling price method allocates total arrangement consideration proportionally to each deliverable on the basis of its estimated selling price. In addition,
the amount recognized for any delivered items cannot exceed that which is contingent upon delivery of any remaining deliverables in the arrangement.

A portion of our 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,  we  recognize  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.  We  recognize  revenue  related  to  certain  executory  costs,  including
maintenance and extended warranty, ratable over the term of the underlying arrangements. We recognize revenue related to battery refresh executory costs when
such executory costs are incurred.

For non-essential software arrangements with multiple-deliverables, including license, professional services and maintenance, we recognize license revenue using
the residual method of accounting pursuant to relevant software revenue recognition guidance.

41

Table of Contents

Under the residual method, revenue is recognized when VSOE for fair value exists for all of the undelivered elements in the arrangement, but does not exist for one
or more of the delivered elements in the arrangement. If evidence of fair value cannot be established for the undelivered elements, all of the revenue is deferred
until evidence of fair value can be established, or until the items for which evidence of fair value cannot be established are delivered. We have established VSOE
for post installation technical support services, which we refer to as maintenance and support. Our revenue arrangements do not include a general right of return
relative to the delivered products.

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
initially  as  financing  liabilities,  with  subsequent  amortization  recorded  in  revenue  for  maintenance,  extended  warranty  and  battery  refresh  programs,  offset  by
interest expense.

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 2015 was $0.9 million, compared
to $0.7 million in 2014 and $1.7 million in 2013. 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

Stock options

We record all stock-based awards, which consist of stock option grants, 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 expenses relating to these awards have been reflected in our financial statements. Stock options granted to our
employees vest over periods of 12 to 48 months.

We use the Black-Scholes option-pricing model to calculate the fair value of stock options on their grant date. This model requires the following major inputs: the
estimated fair value of the underlying common stock, the expected life of the option, the expected volatility of the underlying common stock over the expected life
of the option, the risk-free interest rate and expected dividend yield. The following assumptions were used for each respective period for employee stock-based
compensation:

Expected term (in years)

Volatility

Risk-free interest rate

Dividend yield

Years ended December 31,

2015

5.39

41.3% - 41.8% 

1.62% - 1.63%

0.0%

2014

5.41-5.45

41.4% - 48.2%

1.59% - 1.78%

0.0%

2013

5.38 - 5.43

46.7% - 48.1%

0.81% - 1.80%

0.0%

We base the risk-free rate for the expected term of options on the U.S. Treasury Constant Maturity Rate as of the grant date. The computation of expected life was
determined  based  on  the  historical  exercise  and  forfeiture  behavior  of  our  employees,  giving  consideration  to  the  contractual  terms  of  the  stock-based  awards,
vesting schedules and expectations of future employee behavior. The expected stock price volatility for our common stock was estimated based on the historical
volatility of a group of comparable companies for the same expected term of our options. The comparable companies were selected based on industry and market
capitalization data. We assumed the dividend yield to be zero, as we have never declared or paid dividends and do not expect to do so in the foreseeable future.

Stock-based  compensation  expense  is  recognized  based  on  a  straight-line  amortization  method  over  the  respective  vesting  period  of  the  award  and  has  been
reduced for estimated forfeitures. We estimated the expected forfeiture rate based on our historical experience, considering voluntary termination behaviors, trends
of actual award forfeitures, and other events that will impact the forfeiture rate. To the extent our actual forfeiture rate is different from our estimate, the stock-
based compensation expense is adjusted accordingly.

Restricted Stock Units

During the year ended December 31, 2012, we began incorporating restricted stock units as an element of our compensation plans. Beginning in May 2012, we
granted certain employees restricted stock units, which 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. We did not grant any restricted stock units prior to May 2012. 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. Beginning with 2012, RSU's have formed the largest
amount of stock compensation expense, in terms of grant type.

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 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 historical annual assessment date was September 30 and the results of our assessment performed as of September 30, 2015 indicated no
impairment had been incurred. During the fourth quarter of fiscal 2015 we changed our annual assessment date from September 30th to October 1st to better align
with our forecasting calendar. Further, we updated our goodwill impairment assessment as of October 1, 2015. No impairment was recorded in 2015 , 2014 or 2013
. As of December 31, 2015 , 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 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  asset  group,  given  that  the  Product  asset  group  is  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 2015 , 2014 or 2013 .

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

43

Table of Contents

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, 2015 , 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, 2015 , we had a valuation allowance against net deferred tax assets of $36.0 million . We intend to review on a quarterly basis our conclusions
about the appropriate amount of our deferred tax asset valuation allowance. There is inherent uncertainty 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  2008  are  subject  to  tax  authority
examinations. Additionally, our net operating losses and research credits prior to 2015 are subject to tax authority adjustment.

Recently issued accounting guidance

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 standard will also introduce additional disclosures,
changes in asset and liability accounting, and changes in gain/loss recognition for asset transfers unrelated to customer transactions.

In July 2015 the FASB affirmed a one-year deferral of the effective date of the new revenue standard. Our effective date for this standard will be the first quarter of
2018.  Early  adoption  is  permitted  but  not  before  the  original  effective  date  of  annual  reporting  periods  beginning  after  December  15,  2016.  Two  methods  of
transition are provided: a full retrospective approach, with certain practical expedients allowed, and a cumulative effect method, with balance sheet adjustment as
of  January  1,  2018.  We  are  evaluating  the  effect  the  new  standard  will  have  on  our  consolidated  financial  statements  and  related  disclosures.  We  have  not  yet
selected a transition method nor have we determined the future effect of the standard on our financial position or results of operations.

In November 2015, the FASB issued new guidance to eliminate the requirement for companies to separate deferred income tax liabilities and assets into current
and noncurrent amounts on the balance sheet. Instead, we will be required to classify all deferred tax liabilities and assets as noncurrent. We elected to early adopt
this new guidance during the fourth quarter of fiscal year 2015 on a prospective basis, which did not result in a material change to our financial statements. Prior
periods were not retrospectively adjusted.

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 for us beginning on January 1, 2019 using a modified retrospective approach. The modified retrospective approach includes a number of optional
practical expedients that entities may elect to apply. We have not yet selected a transition method nor have we determined the future effect of the standard on our
financial position or results of operations.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

44

Table of Contents

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, 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 Board of Directors and Stockholders of Vocera Communications, Inc.

San Jose, California

We have audited the accompanying consolidated balance sheets of Vocera Communications, Inc. and subsidiaries (the "Company") as of December 31, 2015 and
2014, and the related consolidated statements of operations, comprehensive loss, stockholders' equity, and cash flows for each of the two years in the period ended
December 31, 2015. These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial
statements based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we
plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. The Company is not required to
have, nor were we engaged to perform, an audit of its internal control over financial reporting. Our audits included consideration of internal control over financial
reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness
of the Company's internal control over financial reporting. Accordingly, we express no such opinion. An audit also includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position of Vocera Communications, Inc. and
subsidiaries as of December 31, 2015 and 2014, and the results of their operations and their cash flows for each of the two years in the period ended December 31,
2015 in conformity with accounting principles generally accepted in the United States of America.

The Company and Summary of Significant Accounting Policies

Notes to Consolidated Financial Statements

Background

Vocera  Communications,  Inc.  and  its  subsidiaries  (the  "Company”)  is  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  U.S.  and  internationally.  The
significant majority of the Company's business is generated from sales of its solutions in the healthcare market to help our customers improve patient safety and
experience, and increase operational efficiency. As of December 31, 2015, the Company's solutions have been selected by in more than 1,400 facilities worldwide.

The Vocera Communication System, which includes an intelligent enterprise software platform, a lightweight, wearable, voice-controlled communication badge,
and 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
securely delivers text messages and alerts directly to and from smartphones, replacing legacy pagers.

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  and  Vocera  Communications
Middle East FZ LLC in 2014.

Since its inception, the Company has incurred significant losses and, as of December 31, 2015 , had an accumulated deficit of $109.8 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, before  the IPO, from  the issuances  of convertible  preferred  stock and from  borrowings under its term loan
facility and the utilization of its line of credit. As of December 31, 2015 , the Company had cash, cash equivalents and short-term investments of $116.8 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).

Use of estimates

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  component  of  the  Company’s  products  is  currently  manufactured  by  a  third-party  contractor  in  Mexico.  A  significant  disruption  in  the
operations of this contractor 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, 2015 and 2014 , no customer accounted for 10% or more of accounts receivable. For the years ended December 31, 2015 ,
2014 and 2013 , 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.

Software development costs 

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, 2015 , 2014 and 2013 , the Company capitalized costs of zero , $0.2 million and $2.1 million , respectively.

Goodwill and intangible assets

55

   
 
 
 
 
 
 
 
Table of Contents

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, we 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  our  qualitative  assessment  indicates  that  goodwill  impairment  is  more  likely  than  not,  we  perform  a  two-step  impairment  test.  The
Company performed its goodwill impairment assessment on September 30, 2015 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. During the fourth quarter of fiscal 2015 the Company
changed its annual assessment date from September 30th to October 1st to better align with its forecasting calendar. The Company updated its goodwill impairment
assessment as of October 1, 2015 which determined that no impairment existed. As of December 31, 2015 , 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  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,
2015 , 2014 or 2013 .

Revenue recognition

The Company derives revenue from the sales of communication badges, smartphones, perpetual software licenses for software that is essential to the functionality
of the communication badges, software maintenance, extended product warranty and professional services. The Company also derives revenue from the sale of
licenses for software that is not essential to the functionality of the communication badges, which may include Clinical Integration and Vocera Collaboration Suite
as well as certain subscription-based revenues including Vocera Care Experience. Sales tax is excluded from reported total revenue.

Revenue is recognized when all of the below criteria are met:

•
•
•
•

there is persuasive evidence that an arrangement exists, in the form of a written contract, amendments to that contract, or purchase orders from a third party;
delivery has occurred or services have been rendered;
the price is fixed or determinable after evaluating the risk of concession; and
collectability is reasonably assured based on customer creditworthiness and past history of collection.

In arrangements  with multiple  deliverables,  assuming  all  other  revenue  criteria  are  met,  the  Company recognizes  revenue  for individual  delivered  items  if they
have value to the customer on a standalone basis. The Company allocates arrangement consideration at the inception of the arrangement to all deliverables using
the  relative  selling  price  method.  This  method  requires  us  to  determine  the  selling  price  at  which  each  deliverable  could  be  sold  if  it  were  sold  regularly  on  a
standalone basis. When available, we use vendor-specific objective evidence ("VSOE") of the selling price. VSOE represents the price charged for a deliverable
when it is sold separately, or for a deliverable not yet being sold separately, the price established by management with the relevant authority. The Company has
established  VSOE  of  the  selling  price  for  our  post-installation  technical  support  services.  When  VSOE  of  selling  price  is  not  available,  third-party  evidence
("TPE") of selling price for similar products and services is acceptable; however, our offerings and market strategy differ from those of our competitors, such that
the  Company  cannot  obtain  sufficient  comparable  information  about  third  parties'  prices.  If  neither  VSOE  nor  TPE  are  available,  the  Company  uses  its  best
estimates  of  selling  prices  ("BESP").  The  Company  determines  BESP  considering  factors  such  as  market  conditions,  sales  channels,  internal  costs  and  product
margin objectives and pricing practices. The Company regularly reviews and update our VSOE and BESP information.

The relative selling price method allocates total arrangement consideration proportionally to each deliverable on the basis of its estimated selling price. In addition,
the amount recognized for any delivered items cannot exceed that which is contingent upon delivery of any remaining items in the arrangement.

56

 
Table of Contents

A typical sales arrangement involves multiple elements, such as sales of communication badges, perpetual software licenses, professional services and maintenance
services which entitle customers to unspecified upgrades, bug fixes, patch releases and telephone support. Revenue from the sale of communication badges and
perpetual software licenses is recognized upon shipment or delivery at the customers’ premises as the contractual provisions governing sales of these products do
not  include  any  provisions  regarding  acceptance,  performance  or  general  right  of  return  or  cancellation  or  termination  provisions  adversely  affecting  revenue
recognition. Revenue from the sale of maintenance services on software licenses is recognized over the period during which the services are provided, which is
generally one year. Revenue from professional services is recognized either on a fixed fee basis based on milestones or on a time and materials basis as the services
are provided, both of which generally take place over a period of two to twelve weeks.  

For  non-essential  software  arrangements  with  multiple-deliverables,  including  license,  professional  services  and  maintenance,  the  Company  recognizes  license
revenue using the residual method of accounting pursuant to relevant software revenue recognition guidance. Under the residual method, revenue is recognized
when  VSOE  for  fair  value  exists  for  all  of  the  undelivered  elements  in  the  arrangement,  but  does  not  exist  for  one  or  more  of  the  delivered  elements  in  the
arrangement.  If  evidence  of  fair  value  cannot  be  established  for  the  undelivered  elements,  all  of  the  revenue  is  deferred  until  evidence  of  fair  value  can  be
established,  or  until  the  items  for  which  evidence  of  fair  value  cannot  be  established  are  delivered.  The  Company  has  established  VSOE  for  maintenance  and
support. The Company's revenue arrangements do not include a general right of return relative to the delivered products.

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, ratable 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, 2015 , the Company transferred $1.5 million  of lease receivables, recording an immaterial net loss and   $0.9 million  of new
financing liabilities for future performance of executory service obligations. For the year ended December 31, 2014 , the Company transferred $1.4 million of lease
receivables, recording an immaterial net gain and  $0.6 million  of new financing liabilities for future performance of executory service obligations.

For lease receivables retained as of December 31, 2015 and 2014 , the Company recorded  $1.5 million and $0.9 million , respectively, of net investment in sales-
type leases, equivalent to the minimum lease payments for the delivered product.

Commissions expense

Sales commissions  are  recorded  as  sales  and marketing  expense  and accrued  as a current  liability  as orders  are  recorded;  thus  no contract  acquisition  costs are
capitalized.

Shipping and handling costs

Shipping  and  handling  costs  charged  to  customers  are  included  in  revenue  and  the  associated  expense  is  recorded  in  cost  of  products  sold  in  the  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 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 revenues, 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.

Advertising costs

57

Table of Contents

Advertising costs are included in sales and marketing expense and are expensed as incurred. Advertising costs for the years ended December 31, 2015 , 2014 and
2013 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 sales.

Stock-based compensation

For options granted to employees, stock-based compensation is measured at grant date based on the fair value of the award and is expensed on a straight-line basis
over the requisite service period. The Company determines the grant date fair value of the options using the Black-Scholes option-pricing model. Restricted stock
awards and restricted stock units result in compensation expense, and are recognized on a straight-line basis over the requisite service period, based on the grant
date  closing  stock  price.  Equity  instruments  issued  to  non-employees  are  recorded  at  their  fair  value  on  the  measurement  date  and  are  subject  to  periodic
adjustment as the underlying equity instruments vest. The fair value of options granted to non-employees is amortized over the vesting period, on a straight-line
basis.

For  stock  options  issued  to  employees  and  non-employees  with  specific  performance  criteria,  the  Company  makes  a  determination  at  each  balance  sheet  date
whether the performance criteria are probable of being achieved. Compensation expense is recognized until such time as the performance criteria are met or when
it is probable that the criteria will not be met.

The Company will only recognize a tax benefit from stock-based awards in additional paid-in capital if an incremental tax benefit is realized after all other tax
attributes currently available to the Company have been utilized. In addition, the Company has elected to account for the indirect effects of stock-based awards on
other tax attributes, such as the research tax credit, through its statement of operations.

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, 2015 and 2014, respectively. Accordingly, the Company has recorded a full valuation allowance on its deferred tax assets for these
years.

At December 31, 2015 , the Company had a valuation allowance against net deferred tax assets of $36.0 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.

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 prior to 2015 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, 2015 , 2014 and 2013, 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, 2015 , 2014 and 2013 , the Company billed a related party, the University of Chicago Medical Center (UCMC), $0.4 million,
$0.3 million and $0.5 million, respectively, for consulting services and technology solutions. One of the Company's board members is the President of UCMC.
These  transactions  were  recorded  at  arms-length  prices.  During  the  year  ended  December  31,  2013,  the  Company  billed  a  related  party,  the  Hewlett-Packard
Company, approximately $9,200 for software and support, at arms’ length prices. Through July of 2013 one of the Company’s board members served as Treasurer
& Senior Vice President at Hewlett-Packard.

Recent accounting pronouncements

In  May  2014,  the  Financial  Accounting  Standards  Board  (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 standard
will also introduce additional disclosures, changes in asset and liability accounting, and changes in gain/loss recognition for asset transfers unrelated to customer
transactions.

In July 2015 the FASB affirmed a one-year deferral of the effective date of the new revenue standard. The Company’s effective date for this standard will be the
first quarter of 2018. Early adoption is permitted but not before the original effective date of annual reporting periods beginning after December 15, 2016. Two
methods of transition are provided: a full retrospective approach, with certain practical expedients allowed, and a cumulative effect method, with balance sheet
adjustment as of January 1, 2018. The Company is evaluating the effect the new standard will have on its consolidated financial statements and related disclosures.
The Company has not yet selected a transition method nor has it determined the future effect of the standard on its financial position or results of operations.

In November 2015, the FASB issued new guidance to eliminate the requirement for companies to separate deferred income tax liabilities and assets into current
and noncurrent amounts on the balance sheet. Instead, companies will be required to classify all deferred tax liabilities and assets as noncurrent. The Company has
elected to early adopt this new guidance during the fourth quarter of fiscal year 2015 on a prospective basis as permitted under the standard, which did not result in
a material change to our financial statements. Prior periods were not retrospectively adjusted.

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 for us beginning on January 1, 2019 using a

59

Table of Contents

modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply. The
Company has not yet selected a transition method nor has it determined the future effect of the standard on its financial position or results of operations.

2. 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, 2015 , 2014 and 2013 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.

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,
2015 and 2014 , respectively. There were no liabilities measured at fair value on a recurring basis for these dates.

The financial accounts that are not subject to recurring fair value measurement include trade and other receivables, prepaid expenses and other current assets, total
current liabilities and deferred revenues, both current and long-term. Due to their short maturities, the carrying amounts of these accounts approximate their fair
values.

The  Company  has  determined  that  the  unrealized  losses  on  its  short-term  investments  as  of  December  31,  2015  and  2014  do  not  constitute  an  "other  than
temporary  impairment".  The unrealized  losses for the  short-term  investments  as of  December  31, 2015  and 2014 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 $10.0 million and $10.0 million of goodwill as of December 31, 2015 and 2014 , 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, 2015 all of the Company's goodwill resides in the Product reporting unit. The Company performed an impairment

which determined that no impairment existed. For 2014, the Company performed the annual required test of impairment of goodwill by performing Step 1 under
authoritative accounting guidance. The Company’s annual impairment test indicated that the fair value exceeded the carrying value for each of its reporting units.
For 2015, the Company used the qualitative assessment permitted under authoritative accounting guidance. Among the qualitative factors considered were changes
since the prior impairment 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  /  product  life  cycle  stage  and  earnings  quality  and  sustainability.  No
impairment was recorded in the years ended December 31, 2015 , 2014 or 2013 .

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:

The Company enters into  non-cancelable  purchase  commitments  with its third-party  manufacturer  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,  2015  and 2014 ,
approximately $7.8 million and $1.9 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 April 2016 and March
2022.  In  April  2015,  the  Company  extended  the  lease  on  the  San  Jose,  California  headquarters  through  March  2022.  Total  rent  expense  for  the  years  ended
December 31, 2015 , 2014 and 2013 was $2.3 million , $2.0 million and $2.0 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.

Securities Litigation         

On August 1 and 21, 2013, two putative securities class action suits were filed in the United States District Court for the Northern District of California against the
Company and certain of its officers, its board of directors, a former director and the underwriters for the Company's initial public offering.  On November 20, 2013,
the court consolidated the actions as In re Vocera Communications, Inc. Securities Litigation and appointed Lead Plaintiffs.  Lead Plaintiffs filed their consolidated
complaint on September 19, 2014.   The consolidated complaint names certain current and former officers and directors and the underwriters for the Company's
initial  public  offering  and  secondary  offering  and  alleges  claims  under  Sections  11,  12(a)(2)  and  15  of  the  Securities  Act  and  Section  10(b)  and  20(a)  of  the
Exchange Act based on allegedly false and materially misleading statements and omissions in the registration statement for the Company's initial public offering
and  secondary  offering  and  in  communications  regarding  its  business  and  financial  results.  The  suit  is  purportedly  brought  on  behalf  of  purchasers  of  the
Company's  securities  between  March  28,  2012  and  May  2,  2013,  and  seeks  compensatory  damages,  rescission,  fees  and  costs,  as  well  as  other  relief.    On
November 3, 2014 Defendants moved to dismiss the consolidated complaint. On February 11, 2015, the Court granted Defendants' motion to dismiss the Securities
Act claims, but denied the motion as to the Exchange Act claims, allowing the matter to proceed on that basis. On April 27, 2015 Defendants filed answers to the
consolidated complaint.

In connection with a mediation, an agreement in principle to settle the suit was reached in October 2015. On March 4, 2016, the Court issued an order granting
Lead Plaintiffs' motion for preliminary approval of the settlement. The settlement, which is subject final approval of the Court, calls for payment of $9 million ,
which will be funded entirely by the Company's insurance carriers.

Due to the inherent uncertainties of litigation, the Company cannot accurately predict the ultimate outcome of this matter. The Company is unable at this time to
determine whether the outcome of the litigation would have a material impact on its results of operations, financial condition or cash flow. The Company has not
established any reserve for any potential liability relating to this lawsuit because this contingency is not considered probable and reasonably estimable.

From  time  to  time,  the  Company  may  be  involved  in  other  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.

8. Common Stock and Share-based Compensation

66

 
Table of Contents

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, 2015 , the Company has 1,366,097 shares of common stock reserved for issuance under stock option plans.

Incentive stock option plans

The Company has three equity incentive plans: the 2000 Stock Option Plan (the “2000 Plan”), the 2006 Stock Option Plan (the “2006 Plan”) and the 2012 Stock
Option Plan (the “2012 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.
Under  the  2012  Plan,  the  Company  has  the  ability  to  issue  incentive  stock  options  (“ISOs”),  stock  appreciation  rights,  restricted  stock,  restricted  stock  units
(“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. Options granted to new
hires generally vest over a 4 -year  period  with  25% vesting  at  the  end  of  one  year  and  the  remaining  vest  monthly  thereafter,  options  granted  as  merit  awards
generally vest monthly over a four-year period. Options granted generally are exercisable up to 10 years .

Early exercise of stock options

The  Company  typically  allows  employees  to  exercise  options  granted  under  the  2000  and  2006  Plans  prior  to  vesting.  The  unvested  shares  are  subject  to  the
Company’s repurchase right at the original purchase price. The proceeds initially are recorded as an accrued liability from the early exercise of stock options and
reclassified to common stock as the Company’s repurchase right lapses. At December 31, 2015 , 2014 and 2013 , there were unvested shares in the amount of zero
, 2,358 and 14,360 , respectively, which were subject to repurchase at an aggregate price of zero , $12,000 and $0.1 million , respectively.

At December 31, 2015 , there was $4.0 million of unrecognized  net compensation  cost related  to options which is expected  to be recognized  over a weighted-
average period of 2.19 years

During  the  year  ended  December  31,  2014,  the  Company  modified  35,528 outstanding  restricted  stock  units  and  84,758 stock  options  to  allow  for  continued
vesting of the awards pursuant to the terms of consulting arrangements entered into with the Company’s former Chief Financial Officer and Executive Chairman. 
The stock-based compensation expense recognized during the period and remaining unamortized stock-based compensation expense as of December 31, 2014 for
the awards were not material and were fully recognized by June 30, 2015, the quarter in which the consulting arrangements are expected to terminate.  The share
amounts and related compensation expense are included in the options and RSU tables below, as well as in the income statement allocation table. The Company
did not grant non-employee options in year ended December 31, 2013.

Using the Black-Scholes option-pricing model, the weighted-average grant-date fair value of options granted to employees during the years ended December 31,
2015 , 2014 and 2013 was $3.92 per share, $4.77 per share and $7.34 per share, respectively. Further

The Company uses the Black-Scholes option-pricing model to calculate the fair value of stock options on their grant date. This model requires the following major
inputs: the estimated fair value of the underlying common stock, the expected term of the option, the expected volatility of the underlying common stock over the
expected life of the option, the risk-free interest rate and expected dividend yield. The following assumptions were used for each respective period for employee
stock-based compensation:

Expected Term (in years)

Volatility

Risk-free interest rate

Dividend yield

2013

5.38 - 5.43

46.7% - 48.1%

0.81% - 1.80%

0.0%

The computation of expected term is based on the historical exercise and forfeiture behavior of the Company’s employees, giving consideration to the contractual
terms of the stock-based awards, vesting schedules and expectations of future employee behavior. For the expected term so determined, the risk-free rate is the
U.S. Treasury Rate for that term on the grant date. The Company's expected common stock price volatility is based on the historical volatility of a peer group of
publicly-traded companies, using the same expected term. The peer group was selected based on industry and market capitalization data. The Company assumes
the dividend yield to be zero , as the Company has never declared or paid dividends and does not expect to do so in the foreseeable future.

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, except for the first
offering period which was for 11 months. Additionally, in April 2013, the Company's compensation committee determined that following the February 15, 2013
six-month  offering  period,  the  next  offering  period  under  the  ESPP would last  for  three  months  (commencing  August 15, 2013 and  expiring  on November  14,
2013) and, following the expiration of such offering period, offering periods thereafter will commence on November 15, 2013, and May 15, 2014 and so on, each
consisting of a single six-month purchase period. 

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 year ended December 31, 2015 and 2014 , employees purchased
145,487 and 160,936 shares, respectively, of common stock at an average purchase price of $8.94 and $9.87 , respectively. As of December 31, 2015 , 393,608
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:

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 and 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.

Prior to the April 2012 IPO, outstanding warrants to purchase preferred stock were classified as liabilities, which were adjusted to fair value at each reporting
period until the earlier of their exercise or expiration or the completion of a liquidation event, including the completion of an initial public offering, at which time
the preferred stock warrant liability automatically converted into a warrant to purchase shares of common stock and was reclassified to stockholders’ equity. The
Company recorded an expense in other income (expense), net of $1.6 million for the year ended December 31, 2013 , respectively, to reflect the change in the fair
value of the outstanding preferred stock warrants. Since April 2012, the converted common stock warrants are classified within stockholder's equity.

9. Segments

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 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, 2015 ; accordingly, the Company has recorded a full valuation
allowance on its deferred tax assets.

The Company’s valuation allowance increased by $5.9 million and $9.0 million for the years ended December 31, 2015 and 2014 , respectively. The change in the
2015 and 2014 valuation allowance was primarily due to the addition of current year loss carryforwards.

At December 31, 2015 , the Company had $79.9 million and $34.9 million , respectively, of federal and state net operating loss carryforwards. Included in the
gross  amount,  approximately  $33.9  million  of  net  operating  loss  is  created  by  excess  stock  option  deduction.  An  increase  to  additional  paid-in  capital  within
stockholders' equity will be recorded when the excess stock option deduction reduces the income tax payable.

The federal net operating loss carryforward begins expiring in 2022, and the state net operating loss carryforward begins expiring in 2016, if not utilized.

In addition, the Company has federal research and development tax credits carryforwards of approximately $2.5 million and state research and development tax
credit carryforwards of approximately $3.8 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, 2015, $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 historic 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. For the years ended December 31,
2015 and 2014 , penalties and interest were $29,000 and $13,000 , respectively. 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 2015 are subject to tax authority adjustment and all years after 2008 are still subject to the tax authority examinations.

The Company has not provided for U.S. federal and foreign withholding taxes on $1.4 million of the Company’s non-U.S. subsidiaries’ undistributed earnings as
of December 31, 2015 , since the Company intends to reinvest this amount outside the U.S. indefinitely.

11. Business acquisitions

Acquisition of mVisum net assets

On January 13, 2014 , the Company acquired substantially all assets of mVisum, Inc., an innovative provider of alarm management technology solutions for health
systems  (mVisum),  for  $3.5  million  in  cash  consideration.  The  acquisition  enabled  the  Company  to  enhance  its  existing  platform  with  complementary
communications solutions for healthcare and other mission-critical environments.

The following table presents the fair value of the identifiable assets acquired and liabilities assumed as of the acquisition date:

The  estimated  fair  values  of  identifiable  intangible  assets  were  primarily  determined  using  discounted  cash  flow  models.  The  acquired  intangible  assets  are
amortized over their estimated useful lives of 4.0 to 7.0 years with a weighted average amortization period of 5.7 years.

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  mVisum’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 deductible over fifteen years. The goodwill recorded from the
acquisition of mVisum is attributed to the Product reporting unit.

The Company incurred $0.2 million of acquisition-related costs that were expensed as incurred. These costs are recorded as general and administrative expenses in
the  consolidated  statement  of  operations.  Additionally,  in  connection  with  the  acquisition  the  Company  established  a  retention  bonus  plan  for  mVisum  with
potential additional compensation over a two-year period of approximately $0.5 million , based on achievement of operating objectives and continued employment.
Such amounts are not considered part of the purchase consideration and are being recorded as compensation expense as earned. The acquisition did not result in
material contributions to revenue or net loss in the consolidated financial statements at the acquisition date. Additionally, pro forma financial information is not
provided for consolidated revenue and net loss as such amounts attributable to mVisum were insignificant.

Acquisition of Prana Technologies assets

On  August  8,  2014,  the  Company  acquired  substantially  all  assets  of  Prana  Technologies,  Inc.  (Prana)  for  $3.45 million in cash consideration.  The acquisition
provides  the  Company  with  technology  critical  to  cloud-based  applications  extending  our  communication  and  collaboration  network  to  include  physicians  and
other geographically dispersed users.  The Company believes this will advance its vision of integrating voice, text, and content-based workflows, on a range of
devices and desktop solutions, across all care locations.

The  estimated  fair  values  of  identifiable  intangible  assets  were  primarily  determined  using  discounted  cash  flow  models.  The  non-compete  intangible  has  an
estimated useful life of two years and the in-process research and development was initially classified

as an asset with an indefinite life. During the year ended December 31, 2015, the product offering associated with the in-process research and development became
generally available. This developed technology has an estimated useful life of six years.

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  Prana’s  proprietary  cloud  technology  expanding  upon  and  being  integrated  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 deductible over fifteen years. The goodwill recorded from the acquisition of Prana is attributed to the Product reporting unit.

The agreement also included contingent payments to the selling stockholders payable based on certain employee retention requirements and the achievement of a
post-acquisition  quality  milestone.  The  Company  considered  these  contingent  payments  as  a  compensation  expense  due  to  the  explicit  and  implied  continuing
employment requirements associated with earning such contingent payments. The company paid $0.8 million in compensation-related elements at the acquisition
date,  which  was  amortized  in  2014.  These  costs  are  recorded  primarily  as  general  and  administrative  expenses  in  the  consolidated  statement  of  operations.  In
addition, the Company expensed as incurred $0.1 million of acquisition-related costs.

The  acquisition  did  not  result  in  material  contributions  to  revenue  or  net  loss  in  the  consolidated  financial  statements  since  the  acquisition  date,  other  than  the
compensation elements discussed above. Additionally, pro forma financial information is not provided for consolidated revenue and net loss, since the acquisition
was not material to the consolidated financial statements.

Item 9.

Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

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, 2015 , 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, 2015 .

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, 2015 based on these criteria. This
Annual Report on Form 10-K does not include an attestation report of our registered public accounting firm on our internal control over financial reporting due to
an exemption established by the JOBS Act for "emerging growth companies."

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, 2015 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.
