Industry overview
Vocera provides communication and workflow solutions for mobile workers in healthcare, hospitality, retail, 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 providinglacking “closed loop” communication, workflow standardization, or the scale required by health systems. Further, they often contribute to noisy environments for patients and negatively impact healing, safety, quality of care and operational efficiency.
Broadly, we believe the healthcare industry is placing greater emphasis on the need for better communication and workflow to meet increasing requirements for care quality, efficiency, patient satisfaction and staff safety and resiliency. Hospitals are struggling to attract and retain the needed nurses and other frontline caregivers to meet their demands.The pandemic has resulted in many nurses leaving the profession and hospital administrators are looking for tools and technologies that can help connect and protect frontline caregivers.The need for clinical communication and workflow solutions is being identified as a key technology to improve staff and patient safety, efficiencythroughput, and patient satisfaction. Healthcare providers 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.retention. A number of non-government organizations, such as The Joint Commission, are also requiring improvements in patient safety and quality of care. These forces are driving hospitals to invest in technology and process improvements to manage their operations more efficiently, improve quality of care, and increase patient satisfaction and staff resiliency. Our solutions help hospitals increase productivity and reduce costs by enhancing workflow and improving patient and staff satisfaction through secure, integrated and intelligent communication.

Our strategy
Our goal is to extend our leadership position as a provider of communication and workflow solutions in the healthcare market and add new customers in non-healthcare markets.
Key elements of our strategy include:
 
Expand our business to new U.S. healthcare customers.    We believe our solutions can provide significant value to health systems, hospitals and smaller healthcare facilities. We plan to continue to add new customers among hospitals of all sizes, and expand to outpatient clinics, aged-care and skilled nursing facilities.
We are increasingly selling enterprise level deployments across entire health systems which is resulting in higher average selling prices.


Further expand our footprint within our existing installed customer base.    Typically,    Many of our customers initially deploy our solutions in a fewseveral departments of a hospital and gradually expand to additional departments as they come to fully appreciate its value.the value of the solutions. We have a significant opportunity to up-sell and cross-sell to our existing customers, including into new hospitals that are part of an existing healthcare system customer. Key sales strategies include expanding our footprint at existing customer facilities and capturing additional revenue by cross selling additional solutions.some of our newer solutions like Engage, Ease, Edge, and the Smartbadge. We plan to continue expanding within our existing customers in order to grow our revenue and maintain and improve the customer experience.



Extend our technology advantage and create new product solutions.    We intend to continue our investment in research and development to enhance the functionality of our solutions and further differentiate them from other competing solutions.

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


Invest in partnerships. In order to gain access to clinical data and patient context needed to To create a highlymore efficient communication and workflow system for the entire care team our solution needs to access clinical data and patient context. To enhance that access, we plan to continue to broaden our ecosystem of technology partners, including vendors that provide nurse call systems, patient monitoring systems, analytics and EHRs. We are developing a range of businessadded new partnerships in 2021 and will continue to explore new relationships that broaden our overall market presence and accelerate the sales of our offerings.

We intend to continue to pursue acquisition opportunities that we believe can accelerate the growth of our business.


Grow our international healthcare presence.    Today, in addition to our core U.S. market, we sell into other English-speaking markets, including Canada, the United Kingdom, Australia, New Zealand, and Middle Eastern countries including the United Arab Emirates, Saudi Arabia, Oman and Qatar.

We plan to utilize both our direct sales force and leverage channel partners to expand our presence into other markets over time.


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

Our customer-centric marketing strategy is important toin generating new sales leads as word of mouth promotion and testimonials are some of our most valuable marketing tools. A number of our customers have agreed to participate in video testimonials, white papers and case studies that validate the efficacy and the financial benefits of our solutions. We have been featured in numerous articles and on network television demonstrating increased patient satisfaction, streamlined hospital operations and enhanced employee satisfaction and safety. Additionally, we sponsor numerous customer-led webinars to demonstrate customer success and to let prospective customers hear from their peer group about the positive impact that our solutions have made on their hospitals. Many of our sales leads come from referrals of existing customers or users who have moved from a hospital already using Vocera to a new facility or health system. We also invest in digital outreach to better influence buyers early on in their decision-making to take advantage of changes in buying behavior within our target market.decision-making.
We have an integrated product management organization that manages the full lifecycle of our products and services; from strategy through execution to end-of-life. Our product roadmaps are driven by current and prospective customers and continually validated using primary and secondary research. We collect customer feedback through surveys and focus groups, customer visits, a customer advisory board, user forums and participation in industry standards organizations. Integral to this team are product managers and user experience designers skilled in clinical and operating workflows, and business development resources that create and manage the ecosystems of clinical and technology system partners.
Customers
Our solutions have been selected by nearly 2,800 facilities worldwide. Of these, over 1,700 facilities worldwide, of which nearly 1,5002,300 are hospitals and other healthcare facilities, and approximately 250 of thoseover 400 are outside of the United States. Our healthcare customers include national and international health and hospital systems, large and medium-sized independent and academic hospitals, small hospitals and healthcare facilities, and U.S. governmental hospitals and care facilities. With our diverse customer base we have very low customer revenue concentration.
During 2017 and 2016, non-U.S. markets represented approximately 10.5% and 10.6% of our revenue, respectively. We are developing plans to offer our solutions in a wider range of international markets.
Competition
We do not believe any single competitor offers a similar intelligent communication system to the healthcare market that allows instant, hands-free communication through voice-activated, role-based and activity-based calling, secure texting, and clinical integrations and workflows, and that features an advanced clinical rules engine that unifies data from multiple sources simultaneously on a combination of dedicated, proprietary devices, as well as third-party smartphones and other devices.
At this time, the primary alternative to our system consists of a combination of traditional communication methods utilizing wired phones, wireless in-building phones, smartphones, pagers and overhead paging systems.

The most significant alternative with which we compete for new sales in the hospital are in-building wireless telephones andhospitals is smartphone applications. While we compete with the providers of these wireless phones in making sales to hospitals, theyThese smartphone applications do not at this time purport to containhave the system intelligence, integrated workflow and convenience of our communication and workflow solutions. The marketsolutions and are primarily focused on basic text messaging and simple communications.
Additionally, we compete against EHR companies, which have their own smartphone application for in-building wireless phones is dominatedsecure texting that they continue to enhance. We differentiate our solutions from these vendors by large communications companies such as Cisco Systems, Ascomenabling hands-free communication via our Smartbadge and Spectralink.

Badge and offering a sophisticated rules engine to support more advanced clinical workflows with more than 150 system integrations.
We believe that the use of mobile smartphone apps for healthcare will continue to expand in our target market and may represent a source of competition, but this trend also represents an opportunity to expand our communication solutions with our smartphone applications, which enable all members of the patient's care team to connect to our software platform and participate as users on our Communication system.
We believe that the primary competitive factors at work in our market include:
 
comprehensiveness of the solution, and the features provided and the ability to purchase the complete solution from a single vendor
product performance and reliability
the initial cost and ongoing cost of ownership
customer service and support capabilities

clinical expertise and our deep understanding of clinical workflows and communications challenges
We may face increased competition in the future, including from large, multinational companies or private equity backed organizations with significant resources. Potential competitors may have existing relationships with purchasers of other products and services within the hospital, which may enhance their ability to gain a foothold in our market. In addition, the continuing expansion of our communication and workflow collaboration capabilities may introduce us to a broader set of competitors. These competitors may include companies that provide clinical workflow solutions, enterprise software, cloud-based solutions and electronic health records.
Research and development
Our continued investment in research and development is critical to our business. We have assembled teams of engineers with expertise in various fields, including software, firmware, database design, applications, speech recognition, wireless communication and hardware design. We employ research and development personnel in San Jose, California; San Diego, California; Fort Wayne, Indiana; Knoxville, Tennessee;Orlando, Florida; Toronto, CanadaCanada; Reading, United Kingdom, and Bangalore, India. There were 152211 full-time research and development employees as of December 31, 2017. We also utilized small teams of2021. Finally, we have periodically engaged outsourced development firms and contractors in Indiato help us with the development and Ukraine to assist with quality assurance testing and automation, and targeted development efforts. Our research and development expenditures were $27.7 million, $18.3 million and $17.0 million in 2017, 2016 and 2015, respectively.of certain elements of our software offerings.
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 3033 U.S. patents as of December 31, 2017,2021, including patents on many capabilities of our software platform and communication badge.wearable devices. The expiration dates of these patents range from 20182022 through 2032.2036. One or more utility patents have also been issued in Australia, Canada, India, Japan and the European Patent Office (with validation in Germany, 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 wearable device products to original design manufacturers and contract manufacturers, including Sercomm and SMTC Corporation (SMTC). Our communication badgeVocera Smartbadge is currently built in Taiwan and our Vocera Badge is made 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 (ODMs) in Asia.
These manufacturers are responsible for procuring all the components included in our products, as specified and approved by us. Some of these components are sole-sourced off-the-shelf and some are custom components built exclusively for our products. In the event we are unable to procure certain components, we could be required to redesign some of our products in order to incorporate technology from alternative sources. An unplanned redesign of our products could materially and adversely affect our business.
We require our suppliers to perform both incoming and outgoing product inspections. In addition, we perform in-house quality control and ongoing reliability testing.
We also resell the Spectralink Versity Smartphone and Zebra Technologies MC40-HC and TC51TC52 Android mobile computers.computer. These devices are offered as a bundled solution with our smartphone applications to provide a complete, turnkey solution for our customers’ clinical communication needs.
Employees and Workforce Management
As of December 31, 2017,2021, we had 590745 employees consistingdedicated to our mission of 22improving the lives of healthcare professionals and patients. These consist of 20 in manufacturing and quality operations, 152211 in research and development, 183219 in sales and marketing, 174224 in services and support and 5971 in general and administrative. Our workforce is distributed globally across 6 countries with 586 employees located in the U.S. and 159 located outside the U.S. None of our employees are covered by a collective bargaining agreement or are represented by a labor union. We consider current employee relationsour company culture to be good.a unique asset, and we believe we have maintained excellent relations with our employees.

Vocera’s workforce is governed by various federal, state, and local regulations. We monitor all key employment activities such as hiring, termination, and pay practices for compliance with established regulations globally. The Compensation Committee of our Board of Directors is responsible for monitoring our workforce management, including, among other aspects, management depth and strength assessment, leadership development, talent assessment, diversity, equity, inclusion, and belonging, and our employee experience survey results. While workforce management is overseen at the highest level of our company, it is woven into the everyday fabric of Vocera’s culture.
At Vocera, our people are our greatest asset, a competitive advantage, and are the core component behind our every success. The cultural values we put into action are: build with respect, embrace innovation, think customer first, drive for results and lead with passion. These values are the framework we align with to hire, train, manage and assess the performance of our global employees. We believe these values differentiate us and, in part, allowed us to consistently retain our employees throughout fiscal year 2021, as our attrition rate continues to be lower than benchmark data. Our employee average tenure globally is 4.8 years.
We foster a culture where our employees can thrive both at work and at home. We apply a systemic approach to culture and people and align performance with pay and rewards. As part of Vocera’s dedication to and investment in its employees, we conduct organizational health surveys designed to assess employee engagement, leadership, work environment, and culture.
Diversity, Equity, Inclusion, and Belonging: We embrace diversity and inclusion and strive to provide a rich environment with diverse skills, backgrounds, and perspectives. As of December 31, 2021, 34% of global employees, 28% of leadership positions, and 33% of our board of directors identified as female. In terms of racial and ethnic diversity, 34% of our employees in the United States self-identified as part of a minority group. At Vocera we are committed to diversity, equity, and inclusion. In 2021, we measured our employees' perceptions on this topic and scored at or above industry benchmark. 2021 was a year of program development and growth around this topic including: a comprehensive internal assessment, internal communications campaign, global listening tour, multiple diversity, equity, inclusion, and belonging virtual events, employee resource group development, required management training, and the publishing of our diversity, equity, inclusion, and belonging statement and commitment.
Employee Well-being and Resilience: We provide comprehensive benefits related to health, wellness, mental health and family resources designed to meet the needs of our diverse global workforce. Employee resilience, physical and psychological safety is of paramount importance to us in any year and was of particular focus in 2021 in light of the ongoing COVID-19 pandemic. We enhanced and promoted programs, events, and resources to support our employees' physical, financial, social, emotional, and family’s well-being through our Vocera on Wellness and Employee Assistance Programs. As part of our ongoing response to the pandemic, we provide PPE to our frontline employees, continue to implement new safety protocols, enhance utilization of existing productivity and collaboration tools, and establish structures for timely communication and decision making
10

throughout the changing environment. As a partner to healthcare providers, we connect our purpose and align our safety requirements to stand shoulder to shoulder with our customers. We facilitate frequent town halls to clearly articulate expectations and engage in meaningful dialogue with all employees. As a result of these efforts, we maintain high employee satisfaction results.
People Development: We believe in investing in our employees, and their professional growth and development is a priority for our company. We engage in detailed discussions around succession planning and talent development to achieve business results at all levels. We have robust employee development review discussions where high-performing and high potential employees are identified for future growth opportunities, as well as succession planning for future critical leadership positions. Actions and development plans as a result of this work are ongoing throughout the year. With an emphasis on supporting women in navigating and accelerating their careers, a cohort of employees participated in a career advancement program. With an added focus on developing our leaders, our people managers attended management essentials sessions, and we hosted a customized year-long leadership development program focused on our top talent and future leaders. Due to the prolonged nature of the pandemic, we offered leaders additional training to maintain high employee engagement in a largely remote working environment.
Community and Social Impact: Vocera strongly believes in giving back to local communities by volunteering and making direct donations where our employees live and work. While the global pandemic continued to limit our ability to volunteer in-person in certain regions, our employee-run community involvement council held some in-person and virtual charitable events and was able to make multiple donations to food banks and other regional and national non-profit agencies.
Backlog
Our backlog of undelivered orders, which includes non-cancellable and cancellable amounts, was $64.4$162.1 million and $69.5$109.2 million at December 31, 20172021 and 2016,2020, respectively. Of the current backlog, all but $13.4$84.2 million is expected to be delivered in 2018.2022.
Government regulations and standards
Substantially allA majority of our revenue is derived from the healthcare industry. The healthcare industry is highly regulated and is subject to changing political, legislative, regulatory and other influences. These factors affect the purchasing practices and operations of healthcare organizations, as well as the behavior and attitudes of our users. Representatives of the U.S. federal legislature and agencies have announced plans to reform or revise aspects of the U.S. healthcare system and we expect these efforts to continue over the next several years. We also expect federal and state legislatures and agencies to continue to consider new programs to reform or revise aspects of the U.S. healthcare system. These programs may contain proposals to increase governmental involvement in healthcare or otherwise change the environment in which healthcare industry participants operate.
HIPAA privacy and security standards
In connection with our healthcare communications business, we access personal health information on behalf of our customers. Accordingly, in the United States, we are subject to the Health Insurance Portability and Accountability Act of 1996 (HIPAA), and its implementing regulations, which established uniform standards for certain “covered entities” (healthcare providers engaged in electronic transactions, health plans and healthcare clearinghouses) governing the conduct of certain electronic healthcare transactions and protecting the security and privacy of protected health information. The American Recovery and Reinvestment Act of 2009 included sweeping expansion of HIPAA’s privacy and security standards as reflected in the Health Information Technology for Economic and Clinical Health Act, (HITECH). Among other things, the new law makes certain HIPAA privacy and security standards directly applicable to “business associates” - independent contractors or agents of covered entities that receive or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. Most of our customers are covered entities under HIPAA and, to the extent that we access personal health information on their behalf, we are their “business associates” and are subject to HIPAA and associated contractual obligations, as well as comparable state privacy and security laws.
In addition, we are subject to privacy and security regulations in other jurisdictions. For example, the European Union (EU) adopted the Data Protection Directive (DPD) (officially Directive 95/46/EC), imposing strict regulations and establishing a series of requirements regarding the storage of personally identifiable information on computers or recorded on other electronic media. This has been implemented by all EU member states through national laws. DPD provides for specific regulations requiring all non-EU countries doing business with EU member states to provide adequate data privacy protection when receiving personal data from any of the EU member states. Inin May 2016, the EU formally adopted the General Data Protection Regulation, or GDPR, which will apply to all EU member states beginningbecame effective in May 2018 and will replace the current DPD.2018. The regulation introducesintroduced new data protection requirements in the EU and substantial fines for breaches of the data protection rules. It will increaseincreased our responsibility and liability in relation to personal datainformation that we process and we expect to put in place additional mechanisms ensuringto enhance our compliance with the new EU data protection rules. Additionally, Canada’s Personal Information and Protection of Electronic Documents Act provides Canadian residents with privacy protections in regard to transactions with businesses and organizations in the private sector and sets out ground rules for how private sector organizations may collect, use and disclose
11

personal information in the course of commercial activities. While the United States does not yet have an overarching federal privacy law, several states have enacted or are in the process of enacting state privacy laws. For example, the California Consumer Privacy Act of 2018, or the CCPA, came into effect on January 1, 2020, and became enforceable by the California Attorney General on July 1, 2020, along with related regulations which came into force on August 14, 2020. Additionally, although not effective until January 1, 2023, the California Privacy Rights Act, or the CPRA, which expands upon the CCPA, was passed in the recent election on November 3, 2020. The CCPA requires covered companies to provide new disclosures to California consumers about their data collection, use and sharing practices and provide such consumers new data protection and privacy rights. The CCPA does have an exemption for HIPAA-covered protected health information, however, the CCPA may still apply to other personal information that we collect and process.
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,customers, and damage to our brand and reputation. We endeavor to mitigate these risks through measures we believe to be appropriate for the specific circumstances, including storing personal datainformation 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.information, and training our personnel. We are committed to protecting the confidentiality, integrity, and availability of personal health information we may encounter in the course of our business activities. Accordingly, we have adopted specific policies and procedures addressing the conduct of the company, employees and specific other third parties regarding how to appropriately safeguard such information in the course of daily activities, and our mandatory annual training includes courses on data security and our code of conduct and policies. All employees are required to sign a certification of completion with respect to such training on an annual basis.
Medical device regulation
The U.S. Food and Drug Administration (FDA) regulates certain products, including software-based products, as “medical devices” based, in part, on the intended use of the product and the risk the device poses to the patient should the device fail to perform properly. We have concluded that our communication products are general-purpose communication solutions and are not subject to FDA regulation. However, either the FDA could disagree with our conclusion or changes in our product or the FDA’s evolving regulations could lead to the imposition of medical device regulation on more of our products. In this event, we would be subject to additional regulatory requirements, including the expense of compliance with Medical Device Reporting and Quality System regulation and the potential of liability for failure to comply, and we could be required to obtain 510(k) clearance

or premarket approval of those products from the FDA prior to commercial distribution. Some of the new products acquired as a result of the Extension Healthcare and mVisum acquisitions are regulated by the FDA as Class II medical devices under applicable law and FDA regulations. This includes potentially being subject to the 2.3% excise tax that was initially legislated under the Affordable Care Act, but which has been delayed through 2019 by a moratorium on the tax included in recent Congressional budget legislation passed in January of 2018. Class II devices are devices classified by the FDA as posing a moderate to high risk and therefore subject to both “general controls” and “special controls,” as such terms are defined in the Food, Drug and Cosmetics Act. Further, our other products could become subject to the 2.3% excise tax when it becomes effective, if the FDA were to determine in the future that they constitute medical devices.
Electrical standards and FCC regulations
Our products emit radio frequency energy in the 2.4 and 5.0 GHz spectrum bands for which licensing by U.S. and other regulatory authorities is not required, provided that the products conform to certain requirements, e.g., maximum power output and tolerance of interference from other devices sharing that spectrum band. We subject our products to testing by independent testing laboratories for compliance with the relevant standards issued by various U.S. and international bodies, including the EU (with respect to the “CE” mark), the International Electrotechnical Commission, the Australian Communications and Media Authority, Underwriters Laboratories and CSA International.
Information about segment and geographic revenue
Information about segment and geographic revenue is set forth in Note 9 of the Notes to Consolidated Financial Statements under Item 8 of this Annual Report on Form 10-K. In addition, financial information regarding our operations, assets and liabilities, including our total net revenue and net income (loss) for the years ended December 31, 2017, 2016 and 2015, and our total assets as of December 31, 2017 and 2016, is included in our Consolidated Financial Statements under Item 8 of this Annual Report on Form 10-K.

Item 1A.Risk Factors
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.

Summary of Risk Factors

Our business is subject to a number of risks and uncertainties, including those risks discussed at-length below. These risks include, among others, the following:
The Transaction (as defined herein), the pendency of the Transaction or our failure to complete the Transaction could have a material adverse effect on our business, results of operations, financial condition and stock price.
We have incurred significant losses in the past and will likely experience losses in the future.
We depend on sales in the healthcare market for the majority of our revenue, and a decrease in sales in the healthcare market would harm our business.
Our sales cycle and our deployment timelines can be lengthy and unpredictable, which may cause our revenue and operating results to fluctuate significantly.
If we fail to offer high-quality products and services, our operating results and our ability to sell these in the future will be harmed.
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 depend on some 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.
Because we depend on contract manufacturers and original design manufacturers, our operations could be harmed and we could lose sales if we encounter problems with these manufacturers.
If we fail to forecast our manufacturing requirements accurately or fail to properly manage our inventory with our contract manufacturers, we could incur additional costs or experience manufacturing delays that could impact the timing of our revenue recognition and adversely affect our operating results.
If we fail to successfully develop and introduce new solutions and features to existing solutions, our revenue, operating results, and reputation could suffer.
The COVID-19 outbreak has had a material impact on the U.S. and global economies and could have a material adverse impact on our employees, suppliers, manufacturing and customers, which could adversely and materially impact our business, financial condition and results of operations.
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.
Our revenue and operating results have fluctuated, and are likely to continue to fluctuate, making our quarterly results difficult to predict, which may cause us to miss analyst expectations and may cause the price of our common stock to decline.
Developments in the healthcare industry and governing regulations have negatively affected and may continue to negatively affect our business.
If we fail to increase market awareness of our brand and solutions, and expand our sales and marketing operations, our business could be harmed.
Failure to protect our information technology infrastructure against cyber-based attacks, network security breaches, service interruptions, or data corruption could significantly disrupt our operations and adversely affect our business and operating results.
Our international operations subject us, and may increasingly subject us in the future, to operational, financial, economic and political risks abroad.
Our efforts to sell our solutions in non-healthcare markets may 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.
We have indebtedness in the form of convertible senior notes. The provisions of indenture for the 2023 notes and 2026 notes (the Notes), accounting method for the Notes and capped call transactions entered into related to the Notes could have a material effect on our operating results, value of the Notes and our common stock or may deter or prevent a business combination.

Risks related to our business and industry


The Transaction, the pendency of the Transaction or our failure to complete the Transaction could have a material adverse effect on our business, results of operations, financial condition and stock price.
On January 6, 2022, we entered into an Agreement and Plan of Merger (the “Merger Agreement”), with Stryker Corporation, a Michigan corporation (“Parent” or “Stryker”), and Voice Merger Sub Corp., a Delaware corporation and a direct or indirect wholly owned subsidiary of Parent (“Merger Sub” or “Purchaser”). The Merger Agreement provides that, subject to the terms and conditions of the Merger Agreement, Merger Sub would commence a cash tender offer (the “Offer”) to purchase all of the outstanding shares of our common stock at a price per share equal to $79.25 (the “merger consideration”), net to the seller in cash, without interest, and subject to withholding taxes required by applicable law (the “Offer Price”).
Following the expiration of the Offer and the acceptance by Merger Sub of the tendered shares in the Offer, on the terms and subject to the conditions in the Merger Agreement, Merger Sub would merge with and into Vocera, with Vocera continuing as the surviving corporation and becoming a wholly owned subsidiary of Stryker (the “Merger” and collectively with the Offer, the “Transaction”), and each then-outstanding share of our common stock (with certain limited exceptions) would be converted into the right to receive the Offer Price. Consummation of the Transaction is subject to various conditions, including, in respect of Merger Sub’s obligation to purchase and accept the tendered shares in the Offer, the condition that the number of shares validly tendered and not properly withdrawn prior to the Expiration Time (as defined in the Merger Agreement) is, when added to the shares, if any, owned by Parent, Merger Sub, or any subsidiary of Parent, represents at least a majority of all shares of our common stock then outstanding. The tender offer expires at one minute after 11:59 p.m., Eastern time, on February 22, 2022. The Transaction is expected to close in the first quarter of 2022, subject to the satisfaction of customary closing conditions. However, there is no assurance that all of the various conditions to the Transactions will be satisfied, or that the Transaction will be completed on the proposed terms pursuant to the Merger Agreement, within the expected timeframe, or at all. Furthermore, there are additional inherent risks to the Transaction, including the risks detailed below.
During the period prior to the closing of the Transaction, our business is exposed to certain inherent risks due to the effect of the announcement or pendency of the Transaction on our business relationships, financial condition, operating results and business, including:
potential uncertainty in the marketplace, which could lead current and prospective customers to purchase offerings from other providers or delay purchasing from us.
the possibility of disruption to our business and operations, including diversion of management attention and resources from ongoing business operations.
the inability to attract, hire and retain key personnel, and the possibility that our current employees could be distracted, and that their productivity may decline as a result, due to uncertainty regarding the Transaction.
the inability to pursue alternative business opportunities or make changes to our business pending the completion of the Transaction, and other restrictions on our ability to conduct our business contained in the Merger Agreement.
unexpected costs, fees, expenses and charges related to the Merger Agreement and the Transaction.
other developments beyond our control, including, but not limited to, changes in domestic or global economic conditions, political conditions, regulatory requirements, licensing requirements and tax matters.

The Transaction may be delayed, and may ultimately not be completed, due to a number of factors, including:
less than the requisite percentage of our stockholders support the proposed Transaction and tender their shares.
the possibility that competing offers or acquisition proposals for our business will be made.
stockholder litigation, which could result in significant costs of defense, indemnification and liability.
the failure by Parent and Merger Sub to obtain the necessary financing to complete the Transaction.
the failure to satisfy any or all conditions to the completion of the Transaction, including the possibility that a Company Material Adverse Effect (as defined in the Merger Agreement) would permit Parent not to close the Transaction.
the occurrence of any other event, change or other circumstance that could give rise to the termination of the Merger Agreement, including in circumstances that would require us to pay a termination fee or other expenses.

If the Transaction does not close, our business and stockholders would be exposed to additional risks, including:
to the extent that the current market price of our stock reflects an assumption that the Transaction will be completed, the price of our common stock could decrease if the Transaction is not completed.
investor confidence could decline, additional stockholder litigation could be brought against us, relationships with existing and prospective customers, service providers, investors, lenders and other business partners may be adversely impacted, we may be unable to retain key personnel, and profitability may be adversely impacted due to costs incurred in connection with the pending Transaction.

the requirement that we pay a termination fee of $108.7 million to Parent if the Merger Agreement is terminated in certain circumstances.

Even if successfully completed, the Transaction has certain consequences and poses certain risks to our stockholders, including:
the fact that receipt of the all-cash per share consideration under the Merger Agreement will generally be taxable to stockholders that are treated as U.S. holders for U.S. federal income tax purposes.
the fact that, if the Transaction is completed, we will no longer operate as an independent public company and our stockholders will forgo the opportunity to realize potential growth and profits, including any potential growth in sales and revenues that could have resulted if we had remained independent, in future prices for our common stock in excess of the $79.25 per share offer price.

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 $14.2$8.5 million for the year ended December 31, 2017.2021. As of December 31, 2017,2021, we had an accumulated deficit of $141.7$153.3 million. If we cannot make consistent progress toward future profitability, our business and our stock price may be adversely affected.
Our ability to be profitable in the future depends upon continued demand for our solutions from existing and new customers. Further market adoption of our solutions including increased penetration within our existing customers, depends upon our ability to improve quality of care, andenhance patient and staff satisfaction, and increase hospital efficiency and productivity, and bring value to customers outside of healthcare. In addition, our profitability will be affected by, among other things, our ability to execute on our business strategy, the timing and size of orders, the pricing and costs of our solutions, competitive offerings, macroeconomic conditions affecting the health care industry and the extent to which we invest in sales and marketing, research and development and general and administrative resources.



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


To date, substantially all of our revenue has been derived from sales to the healthcare market and, in particular, hospitals. Sales to the healthcare market accounted for 98%, 97%98% and 98%96% of our revenue for the years ended December 31, 2017, 20162021, 2020 and 2015,2019, respectively. We anticipate that sales to the healthcare market will represent a significant portion of our revenue for the foreseeable future.
Most of our solutions require a substantial upfront investment by new customers. The cost of the initial deployment depends on the number of users and departments involved, the size and age of the hospital and the condition of the existing wireless and technology infrastructure, if any, within the hospital. Even if hospital personnel determine that our solutions provide compelling benefits over their existing communications methods, their hospitals may not have, or may not be willing to spend, the resources necessary to install and maintain wireless and technology infrastructure to initially deploy and support our solutions or expand our solutions to other departments or users. Hospitals face significant budget constraints from the COVID-19 pandemic, as they have had to postpone elective procedures that provide a significant portion of their revenue. Hospital budgets are also constrained by 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 fromwhich add to these budget pressures. Also as part of the implementation oftax reform law that came into effect in December 2017, the tax penalty for violating the individual health insurance mandate under the Patient Protection and Affordable Care Act of 2010 (ACA) and now face uncertainty aswas set to zero effective in 2019, essentially repealing it. It is uncertain if there will be changes to the President ofACA, but there have been attempts in the United States and members of the legislature have announced their intention to attemptpast to repeal or reformamend the ACA, as well as continue to undertake other healthcare reform.reforms. As a consequence weof these regulatory and other factors, hospitals may experiencedelay or reduce their spending, which may cause slowdowns and deferral of orders for our solutions, thator customers may choose other less expensive solutions, both of which could negatively impact our sales. We might not be able to sustain or increase our revenue from sales of our solutions, or achieve the growth rates that we envision, if hospitals continue to face significant budgetary constraints and reduce their spending on communications systems.
While we are seeking

Our sales cycles and our deployment timelines can be lengthy and unpredictable. Our sales efforts involve educating our customers about the use and benefits of our solutions, to non-healthcare customers, we do not anticipate non-healthcare markets to representincluding the technical capabilities of our solutions and the potential cost savings and productivity gains achievable by deploying them. Customers typically undertake a significant portionevaluation process, which frequently involves not only our solutions but also their existing communications methods and those of our competitors and can result in a lengthy sales cycle that sometimes exceeds twelve months.

We have experienced and may continue to experience elongated sales cycles due to ongoing uncertainty caused by the COVID-19 pandemic, as well as past and future healthcare reform legislation, the impact of shifting federal government budgets, changes to Medicare and Medicaid reimbursement and potential future statutes and rule making.


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


Our ability to sell our solutions is dependent upondepends on our professional servicesability to offer high-quality product and technical support teams providing high-quality servicesservices. Our solutions incorporate complex technology, are deployed in a variety of complex hospital environments and support. 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 to interoperate with nurse call systems, device alarms and other hospital systems. Our software may be partnered with third party software to provide for potential joint solutions with such third party. Our software may also be deployed on third party devices, including devices we resell, which creates additional complexity because we share control of the customer experience. If we cannot successfully integrate our solutions with these vendors as needed or if any hardware or software of these vendors contains any defect or error, then our solutions may not perform as designed, or may exhibit a defect or error.
Our professional services team assists our customers with their wireless infrastructure assessment, clinical workflow design, communication solution configuration, clinical integration, training and project management during the pre-deployment and deployment stages. Once our solutions are deployed within a customer’s facility, the customer typically depends on our technical support team to help resolve technical issues, assist in optimizing the use of our solutions and facilitate adoption of new functionality. In some cases, we also use third parties to provide professional services to our customers, which means that we have less control over how these services are performed. If we do not effectively assist our customers in deploying our solutions, succeed in helping our customers quickly resolve technical and other post-deployment issues, or provide effective ongoing support services, our ability to expand the use of our solutions with existing customers and to sell our solutions to new customers will be harmed. If deployment of our solutions is deemed unsatisfactory, we may incur significant costs to attain and sustain customer satisfaction or, in extreme cases, our customers may choose not to deploy our solutions. As we rapidly hire new services and support personnel, we may inadvertently hire underperforming people who will have to be replaced, or fail to effectively train such employees, leading in some instances to slower growth, additional costs and poor customer relations. In addition, the failure of channel partners or other outsourced professional support contractors to provide high-quality services and support in markets outside the United States could also harm sales of our solutions.
Any defects or errors in, or which are attributed to our solutions, or to products or services we resell, could result in:
delayed market acceptance of our affected solutions;
loss of revenue or delay in revenue recognition;
loss of customers or inability to attract new customers;
diversion of engineering or other resources for remedying the defect or error;
damage to our brand and reputation;
delay in delivery of information;
increased service and warranty costs, including potential replacement costs for product recalls or returns; and
legal actions by our customers and hospital patients, including product liability claims.
If any of these occur, our operating results and reputation could be harmed.
As we continue to pursue opportunities for larger deals that have greater technical complexity, including deals that include the Engage software,require more complex integrations with our customers' workflows, we may experience a longer time period for the dealsour solutions to deploy and as a result, our revenue recognition for these deals may be delayed. Additionally, as we enter agreements with new and existing customers for larger and more complex deals across multiple sites, we have been, and may continue to be, required to agree to customer acceptance and cancellation clauses. DelaysWith 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 Cancellation clauses 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, effortcustomer canceling an order for our hardware, software and money in our sales efforts without any assurance that our efforts will produce sales. Similarly, our increasing dependence on larger, hospital-wide deployments may increase fluctuations in our revenue and operating results because the failure to complete a significant sale, or the loss of a large customer will have a greater

impact on those results.In addition, purchases of our solutions are frequently subject to budget constraints, multiple approvals, and unplanned administrative, processing and other delays. For example, we experienced elongated sales cycles due to uncertainty surrounding healthcare reform and lower hospital admission trends in 2013 and 2014, and it is possible that the current uncertainty about healthcare will extend hospital sales cycles. Hospitals in the U.S. continue to face significant uncertainty over the continuing impact of federal government budgets, and continuing changes in the implementation and deadlines for compliance with the ACA, the potential repeal or reform of the ACA, changes to Medicare and Medicaid reimbursement, Federal budgeting in the Veterans Administration and Department of Defense, 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 hire additional direct sales, professional services, and marketing personnel domestically and internationally, acquire complementary businesses, technologies or assets, and increase our investment in research and development. Our future operating results depend to a large extent on our ability to successfully implement such plans and manage such investments. To do so successfully we must, among other things:
manage our expenses in line with our operating plans and current business environment;
maintain and enhance our operational, financial and management controls, reporting systems and procedures;
integrate acquired businesses, technologies or assets;
manage operations in multiple locations and time zones; and
develop and deliver new solutions and enhancements to existing solutions efficiently and reliably.

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;
the availability of government funding for healthcare facilities operated by the United States federal government;
changes in the regulatory environment affecting our healthcare customers, including impediments to their ability to obtain reimbursement for their services;
our ability to expand our sales and marketing operations;
our ability to successfully integrate acquired businesses;
the announcement of new significant contracts or relationships;
the procurement and deployment cycles of our healthcare customers and the length of our sales cycles;
changes in customer deployment timelines;
variations in the amount of orders booked in a prior quarter but not delivered until later quarters;
our mix of solutions and the varying revenue recognition rules that apply;
pricing, including discounts by us or our competitors;
our ability to expand into non-healthcare markets;
our ability to develop significant new reseller relationships and maintain existing reseller relationships;
the financial health of our resellers;
our ability to successfully deploy our solutions in a timely manner;
our ability to forecast demand and manage lead times for the manufacture of our solutions;
our ability to develop and introduce new solutions and features to existing solutions that achieve market acceptance;
fluctuations in foreign currencies in the international markets in which we operate; and

future accounting pronouncements and changes in accounting policies, including our ability to implement the new procedures and processes necessary to accurately recognize and forecast our revenue under the new revenue recognition standard, Accounting Standards Codification No. 606 (ASC 606).

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

We have acquired, and in the future may acquire, complementary businesses, technologies or assets that we believe to be strategic. We may not achieve the anticipated strategic or financial benefits, or be successful in integrating any acquired businesses, technologies or assets. If we cannot effectively integrate the acquired business and products into our business, we may not achieve market acceptance for, or 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;
experience unforeseen and significant problems or liabilities associated with quality, technology and legal contingencies relating to the acquisition, such as intellectual property or employment matters; and
incur substantial costs to integrate the acquired business.

If we were to proceed with one or more additional significant acquisitions in which the consideration included cash, we could be required to use a substantial portion of our available cash. To the extent we issue shares of capital stock or other rights to purchase capital stock, including options and warrants, the ownership of existing stockholders would be diluted. In addition, acquisitions may result in the incurrence of debt, contingent liabilities, large write-offs, or other unanticipated costs, events or circumstances, any of which could harm our operating results.
In addition, from time to time we may enter into negotiations for acquisitions that are not ultimately consummated. These negotiations could result in significant diversion of management time, as well as substantial out-of-pocket costs.

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

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

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

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. Further, the President of the United States and members of the legislature have stated their intent to significantly revise, repeal or reduce funding under the ACA. Uncertainty surrounding the status of the ACA and its regulations may impact the spending of our healthcare customers, and we cannot predict the effect on our business of any new legislation and regulations that may be adopted if the ACA is significantly changed or repealed.
We believe that our healthcare customers are unsure of the impact that a number of the elements of those acts, as well as the related efforts to reform or repeal the ACA will have on their business, and cannot predict the timing and requirements of the final rules issued by the U.S. Department of Health and Human Services (HHS) for these statutes, making managing their business operations more difficult.  Further, as has been experienced since 2010, as rules and agency guidance pursuant to these statutes are implemented and revised by HHS, a number of aspects of the acts have been interpreted, modified or delayed. For example, sudden changes in the rules for individuals buying insurance through state or federal health insurance exchanges, and individual and employer mandates to have and offer insurance coverage, 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. During the year ended December 31, 2017, we generated approximately 18% of our revenue from these customers. These 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 the primary competition for ourOur prospective customers primarily use legacy communication solutions has consisted of traditional methods usingsuch as wired and wireless phones, pagers and overhead intercoms. While weWe believe that our system is superior to these legacy methods, our solutions require a significant infrastructure investment by a hospital and many hospitals’ spending is severely constrained by other priorities.
methods. Manufacturers and distributors of product categories such as cellular phones, smartphone applications, pagers, mobile radios and in-building wireless telephones alsocontinue to sell their products to hospitals as components of communication solutions. Of these product categories, in-building wireless telephones and pagers represent the most significant current competition for the sale of our solutions. The market for in-building wireless phones is dominated by communications companies such as Cisco Systems, Ascom and Spectralink.hospitals. In addition, the growing proliferation of smartphones and related applications, including cloud-based applications, represents another category of competitive offerings. While we consider secure text-messaging using smartphones a feature valued by many customers, we do not believe most ofFurthermore, our potential customers would consider that feature alone an adequate substitute for a comprehensive multi-mode communication solution. Some customers may choose solutions that are not HIPAA-compliant, given their budget constraints. Furthermore, in clinical integrations and middleware wesolutions compete with a variety of companies including Connexallthat offer clinical integration technology. Similarly we may face a different set of competitors in our patient and Philips Healthcare.family engagement solutions.

While we do notWe believe currently have athere is no directly comparable single competitor that provides a solution as richly-featured as the Vocera Communication and Workflow System for the healthcare market as richly-featured as ours, but we could face such competition in the future. Potential competitors in the healthcare or communications markets include large, multinational companies with significantly more resources to dedicate to product development and sales and marketing. These companies, which may include electronic health record vendors or other large software and healthcare IT companies, may have existing relationships within the hospital, which may enhance their ability to gain a foothold in our market. For example, some of the electronic health record vendors have started to offer secure text messaging as an additional service. Customersservice and have said they plan to expand these offerings to complete more directly with us. Some 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. In addition, our acquisition of Extension Healthcare may introduce us to a broader set of competitors.

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

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

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

We rely on information technology and telephone networks and systems, including the Internet, to process and transmit sensitive electronic information and to manage or support a variety of business processes and activities, including sales, billing, customer service, procurement and supply chain. We use enterprise information technology systems to record, process, and summarize financial information and results of operations for internal reporting purposes and to comply with regulatory financial reporting, legal, and tax requirements. Our information technology systems, some of which are managed by third-parties, may be susceptible to damage, disruptions or shutdowns due to computer viruses, attacks by computer hackers, failures during the process of upgrading or replacing software, databases or components thereof, power outages, hardware failures, telecommunication failures, user errors or catastrophic events. Although we have developed systems and processes that are designed to protect 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.


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


We depend on sole and limited source suppliers for several hardware components of our solutions, including our batteries and integrated circuits. We purchase inventory generally through individual purchase orders. Any of these suppliers could cease production of our components, cease to provide the necessary levels of support for our use of their components, experience capacity constraints, material shortages, work stoppages, epidemics or contagious diseases, such as the coronavirus outbreak, that negatively impact them and their suppliers, 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. For example, we have experienced, and may continue to experience periodic delays in deliveries from our suppliers as a result of the COVID-19 pandemic. 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.source if a component becomes unavailable.
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 atwith substantial cost and time investments to incorporate alternative software components or be subject to higher royalty costs. Any of these circumstances could adversely affect the cost and availability of our solutions.
Third-party licensors generally require us to incorporate specific license terms and conditions in our agreements with our customers. If we are alleged to have failed to incorporate these license terms and conditions, we may be subject to claims by these licensors, incur significant legal costs defending ourselves against such claims and, if such claims are successful, be subject to termination of licenses, monetary damages, or an injunction against the continued distribution of one or more of our solutions.

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


We do not have internal manufacturing capabilities and rely upon atwo contract manufacturer,manufacturers, Sercomm and SMTC, to produce the primary hardware component ofmake our solutions.wearable devices. We have entered into a manufacturing agreementagreements with Sercomm and SMTC that isare terminable by either party with advance notice and that may also be terminated for a material uncured breach. We expect to enter into additional contract manufacturing agreements as we expand our business. We also rely on original design manufacturers or ODMs,(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, epidemics or contagious diseases that negatively impact them and their suppliers, financial difficulties, cost increases or other reductions or disruptions in output, cease operations or be acquired by, or enter into exclusive arrangements with, a competitor. If Sercomm, SMTC, or another contract manufacturer or an ODM is unable or unwilling to continue manufacturing components of our solutions in the volumes and timeframes that we require, fails to meet our quality specifications or significantly increases its prices, we may not be able to deliver our solutions to our customers with the quantities, quality and performance that they expect in a timely manner. As a result, we could lose sales and our operating results could be harmed.
Sercomm, SMTC, other contract manufacturers or ODMs may experience problems that could impact the quantity and quality of hardware components of our Vocera Communication and Workflow System,solution, including disruptions in their manufacturing operations due to equipment breakdowns, labor strikes or shortages, component or material shortages and cost increases. SMTC, other contract manufacturers and these ODMs generally rely on purchase orders rather than long-term contracts with their suppliers, and as a result, may not be able to secure sufficient components or other materials at reasonable prices or of acceptable quality to build components of our solutions in a timely manner. The majority of the hardware components of our Vocera Communication and Workflow Systemsolution are manufactured in Asia or Mexico, and adverse changes in political or economic circumstances, or health related issues such as epidemics or contagious diseases, in those locations could also disrupt our supply and quality of components of our solutions. For example, there is currently a global shortage of semiconductors that are used in a wide variety of products, including ours. Our contract manufacturers currently have an adequate supply of semiconductors to satisfy our expected demand for 2022, but a prolonged shortage could result in manufacturing delays for our products. In addition, U.S. government officials have recently proposedimposed changes in trade, tariffs, fiscal orand tax policies and may do so in the future, and any such changes in the U.S. or in other countries from which we source components of our products could adversely affect our business.
Companies occasionally encounter unexpected difficulties in ramping up production of new products, and we may experience such difficulties with future generations of our products. Sercomm, SMTC, other contract manufacturers and our ODMs also manufacture products for other companies. Generally, our orders represent a relatively small percentage of the overall orders received by Sercomm, SMTC, other contract manufacturers and these ODMs from their customers; therefore, fulfilling our orders may not be a priority in the event Sercomm, SMTC, other contract manufacturers or an ODM is constrained in its ability to fulfill all of its customer obligations. In addition, if Sercomm, SMTC, other contract manufacturers or an ODM is unable or unwilling to continue manufacturing components of our solutions, we may have to identify one or more alternative manufacturers. The process of identifying and qualifying a new contract manufacturer or ODM can be time consuming, and we may not be able to substitute suitable alternative manufacturers in a timely manner or at an acceptable cost. Additionally, transitioning to a new manufacturer may cause us to incur additional costs and delays if the new manufacturer has difficulty manufacturing components of our solutions to our specifications or quality standards.


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 andor experience manufacturing delays which canthat could impact the timing of our revenue recognition and adversely affect our operating results.


We place orders with our contract manufacturers, including Sercomm and SMTC, and we and our contract managersmanufacturers place orders with suppliers based on forecasts of customer demand. Because of our international low costlow-cost sourcing strategy, our lead times are long and cause substantially more risk to forecasting accuracy than would result were lead times shorter. Our forecasts are based on multiple assumptions, each of which may introduce errors into our estimates affecting our ability to meet our customers’ demands for our solutions. We also may face additional forecasting challenges due to new product introductions, product transitions in the components of our solutions, or to

our suppliers discontinuing production of materials and subcomponents required for our solutions. If demand for our solutions increases significantly, we may not be able to meet demand on a timely basis, and we may need to expend a significant amount of time working with our customers to allocate limited supply and maintain positive customer relations, or we may incur additional costs in order to source additional materials and subcomponents to produce components of our solutions or to expedite the manufacture and delivery of additional inventory. If we underestimate customer demand, we and 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,
18

we and SMTCour contract manufacturers may purchase more inventory than required for actual customer orders, resulting in excess or obsolete inventory, thereby increasing our costs and harming our operating results.

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

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

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

We believe that a significant opportunity exists to continue to sell our products to healthcare facilities in the Veterans Administration and Department of Defense (DoD). These customers require independent certification of compliance with specific requirements relating to encryption, security, interoperability and scalability, including Federal Information Processing Standard (FIPS) 140-2 and, as to DoD, certification by its Joint Interoperability and Test Command and under its Information Assurance Certification and Accreditation Process. We have received certification under certain of these standards for military-specific configurations of our solution incorporating our badges. We continue to carry out further compliance activities and recertifications, as required. A failure on our part to achieve and maintain compliance and to respond to new threats and vulnerabilities, both as to current products and as to new product versions, could adversely impact our revenue.

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

In recent years, we have actively engaged in sales efforts to customers outside the healthcare markets, including hospitality, energy and other mobile work environments. We may not be successful in further penetrating the non-healthcare markets upon which we are initially focusing, or other new markets. To date, our solutions have been selected by over 270 customers in non-healthcare markets. Total revenue from non-healthcare customers accounted for 2%, 3% and 2% of our revenue for the years ended December 31, 2017, 2016 and 2015, respectively. If we cannot maintain these customers by providing solutions that meet their requirements, if we cannot successfully expand our solutions in non-healthcare markets, or if adoption of our solutions 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 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.


Our success depends, in part, upon our ability to develop and introduce new solutions and to add 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 thatrequirements. Similarly, our new solutions and features may not sufficiently differentiate us from competing solutions such that

customers can justify deploying our solutions. We expect to incur costs associated with the development and introduction of new solutions before the anticipated benefits or the returns are realized, if at all. We may experience technical problems and additional costs as we introduce new features to our software platform, deploy future models of our wireless badges, or deploy new smartphone apps, which can require customers to perform software upgrades to their systems, and integrate new solutions with existing customer clinical systems and workflows. In addition, we may face technical difficulties as we expand into non-English speaking countries and incorporate non-English speech recognition capabilities into our solutions. We also may incur substantial costs or delays in the manufacture of any additional new products or models as we seek to optimize production methods and processes at our contract manufacturer.manufacturers. In addition, we expect that we willmay 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.

The COVID-19 outbreak has had a material impact on the U.S. and global economies and could have a material adverse impact on our employees, suppliers, manufacturing and customers, which could adversely and materially impact our business, financial condition and results of operations.
We generally recognize revenue from maintenanceThe ongoing outbreak of coronavirus, SARS-CoV-2 (COVID-19) continues to be a global pandemic and support contractsboth a public health and subscription arrangements overeconomic emergency. Many federal, state and local governments and private entities have mandated and lifted various restrictions, including travel restrictions, restrictions on public gatherings, stay at home orders and advisories and quarantining of people who may have been exposed to the contract term,virus. As the COVID-19 pandemic is complex and rapidly evolving, our business may be negatively affected for a prolonged period of time. At this point, we cannot reasonably estimate the duration and severity of this pandemic, which could have a material adverse impact on our business, results of operations, financial position and cash flows.
The pandemic has affected, and may continue to adversely affect, our customers’ operations, our employees and our employee productivity. It may impact the ability of our customers, subcontractors, partners, and suppliers to operate and fulfill their contractual obligations, and result in an increase in payment defaults, collection costs and/or delays or disruptions in performance. In particular, hospitals and healthcare facilities have prioritized the care and treatment of COVID-19 patients and may have restricted access for most visitors and reduced spending unrelated to COVID-19. These customers have also had to suspend elective procedures in some cases, which generate a majority of their profits, adding to their financial difficulties. While many elective procedures have resumed, it is uncertain whether consumers will seek those procedures due to concerns about COVID-19 and its variants, including Delta and Omicron, and it is also uncertain if elective procedures will be suspended again if cases increase. In response, some have furloughed staff, including those we ordinarily work with to sell and implement our offerings.
Outside of healthcare, some of our clients in the hospitality and retail industries have suspended or modified operations until stay-at-home orders are lifted, and potentially beyond. Although stay-at-home orders have been lifted in many areas, it is uncertain whether consumers will return to those establishments and how successful these businesses will be. As a result, we have experienced delays in planned deployments and changes in customer demand, and could experience additional delays, discounts, customer payment issues, bad debt, potential terminations and unpredictability as our customers continue to respond to the challenges of treating and containing the COVID-19 pandemic.
We have also experienced some disruptions in our supply chain and our manufacturers have similarly experienced disruptions in their supply chains. To the extent our suppliers prioritize the manufacturing of other products or experience facility or business disruptions due to sick employees, stay-at-home orders, supply chain disruptions or otherwise, we may be unable to maintain a sufficient supply of our products to meet demand. Additionally, our employees, in many cases, are working remotely and using various technologies to perform their functions, which may create security risks, inefficiencies and reduced productivity, and reduce the effectiveness of our sales team.
19

These effects on our business, and the direct effect of the virus and the disruption on our employees and operations, may negatively impact our revenue, profit margins and liquidity. Additionally, the disruption and volatility in the global and domestic capital markets may increase the cost of capital and limit our ability to access capital.
The ongoing COVID-19 pandemic has also caused us to modify our business practices including employee travel, customer visits, employee work locations, and cancellation of physical participation in meetings, events and conferences which are important to support our sales approach. We also are requiring our employees to be vaccinated against COVID-19 unless they qualify for an exemption. We may take further actions as may be required by government authorities or that we determine are in the best interests of our employees, customers and business partners. A prolonged disruption or any further unforeseen delay in our operations or within any of our business activities could result in reduced revenue. We could also be adversely affected if government authorities impose additional restrictions or extend the length of restrictions on public gatherings, human interactions, mandatory closures, seek voluntary closures, restrict hours of operations or impose curfews, restrict the import or export of products or if suppliers issue mass recalls of products. There is no certainty that such measures will be sufficient to mitigate the risks posed by the virus or otherwise be satisfactory to government authorities.
Both the health and economic aspects of the COVID-19 virus are highly fluid and the future course of each is uncertain. For these reasons and other reasons that may come to light as the coronavirus pandemic and associated protective or preventative measures develop, we may experience a material adverse effect on our business operations, revenues and financial condition; however, its ultimate impact is highly uncertain and subject to change.

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

We have experienced periods of expansion, relative stability and contraction in our revenues and operations in the past. Such fluctuations have placed, and may continue to place, strains on our management systems, infrastructure and other resources. Especially during growth periods, we hire additional direct sales, professional services and marketing personnel domestically and internationally, acquire complementary businesses, technologies or assets, and increase our investment in research and development. Our future operating results depend to a large extent on our ability to successfully implement such plans and manage such investments. To do so successfully we must, among other things:
manage our expenses in line with our operating plans and current business environment;
maintain and enhance our operational, financial and management controls, reporting systems and procedures;
integrate acquired businesses, technologies or assets;
manage operations in multiple locations and time zones; and
develop and deliver new solutions and enhancements to existing solutions efficiently and reliably.

We expect to incur costs associated with the investments made to support our business strategy before the anticipated benefits or the returns are realized, if any. If we are unable to grow our business or manage our future growth effectively, we may not be immediately reflectedable 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.results have fluctuated, and are likely to continue to fluctuate, making our quarterly results difficult to predict, which may cause us to miss analyst expectations and may cause the price of our common stock to decline.


We generally recognize revenue fromOur 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 customer maintenance and support contracts, extended warranty contracts and subscription arrangements ratably over the contract term, which is typically 12 months, in some cases subject to an early termination right. Revenue from our maintenance and support contracts accounted for 32%, 34% and 37%control.
Comparisons of our revenue for the years ended December 31, 2017, 2016 and 2015, 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,operating results on a decline in new or renewed maintenance and support, extended warranty contracts or subscription agreements by our customers in any one quarterperiod-to-period basis may not be immediately reflectedmeaningful. 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 ongoing impact of the COVID-19 pandemic;
the financial health of our healthcare customers and budgetary constraints on their ability to upgrade their communications, particularly in our revenuelight of the pandemic;
the availability of government funding for that quarter. Such a decline, however, will negatively affect our revenuehealthcare facilities operated by the United States federal, state and local governments;
changes in future quarters. Accordingly, the effect of significant downturns incustomer purchasing patterns or sales and cycles;
market acceptance of our Smartbadge and its impact on orders for our existing Badge and related software;
20

changes in the regulatory environment affecting our healthcare customers, including impediments to their ability to obtain reimbursement for their services;
our ability to expand and improve our sales and marketing operations;
our ability to successfully integrate acquired businesses, technologies or assets;
the announcement of new significant contracts or relationships;
the procurement and deployment cycles of our healthcare customers and the length of our sales cycles;
changes in how healthcare operating and capital budgets are administered by our customers;
changes in customer deployment timelines;
variations in the amount of orders booked in a prior quarter but not delivered until later quarters;
our mix of solutions and the varying revenue recognition rules that apply;
pricing, including discounts by us or our competitors;
our ability to expand into non-healthcare markets;
our ability to develop significant new reseller relationships and maintain existing reseller relationships;
the financial health of our resellers;
our ability to successfully deploy our solutions in a timely manner;
our ability to sell and integrate third-party products and services, and our customer’s satisfaction with those third-party products and services;
our ability to forecast demand and manage lead times for the manufacture of our solutions;
our ability to develop and introduce new solutions and features to existing solutions that achieve market acceptance;
the announcement of a new product, which may cause sales cycles to lengthen;
federal government shutdowns;
occurrence of health epidemics or contagious diseases and potential effects on our business and manufacturing operations;
fluctuations in foreign currencies in the international markets in which we operate; and
future accounting pronouncements and changes in accounting policies.

If we do not achieve the anticipated strategic or financial benefits from our rate of renewalsacquisitions 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. For example, in the prior fiscal year we acquired EASE, a cloud-based communication platform and mobile application, to help enhance care team communication with patients and families, and in the current year, we acquired PatientSafe, a clinical communication and collaboration (CC&C) solution designed for hospitals and health systems that have invested in their EHR mobile workflow software, are smartphone centric, and may prefer a cloud-based CC&C solution. We may not achieve the anticipated strategic or financial benefits, or be fully reflectedsuccessful in integrating EASE or PatientSafe or any acquired businesses, technologies or assets. If we cannot effectively integrate the acquired business and products into our business, we may not achieve market acceptance for, or derive significant revenue from, these new solutions.
Integrating newly acquired businesses, technologies and assets could strain our resources, could be expensive and time consuming, and might not be successful. Our recent acquisitions expose us, and we will be further exposed, if we acquire or invest in additional businesses, technologies or assets, to a number of risks, including that we may:
experience technical issues as we integrate acquired businesses, technologies or assets into our existing solutions;
encounter difficulties leveraging our existing sales and marketing organizations, and direct sales channels, to increase our revenue from acquired businesses, technologies or assets;
find that the acquisition does not further our business strategy, we overpaid for the acquisition or the economic conditions underlying our acquisition decision have changed;
have difficulty retaining key personnel of acquired businesses;
suffer disruption to our ongoing business and diversion of our management’s attention as a result of transition or integration issues and the challenges of managing geographically or culturally diverse enterprises;
experience unforeseen and significant problems or liabilities associated with quality, technology and legal contingencies relating to the acquisition, such as intellectual property or employment matters; and
incur substantial costs to integrate the acquired business.

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

21

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.

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.technology field. If we fail to attract,create work environments viewed as attractive and 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.


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

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

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

Substantially all of our revenue is derived from customers in the healthcare industry, in particular, hospitals. The healthcare industry is highly regulated and is subject to changing political, legislative, regulatory and other influences. Developments generally affecting the healthcare industry, including new regulations or new interpretations of existing regulations, could adversely affect spending on information technology and capital equipment by reducing funding, changing healthcare pricing or delivery or creating impediments for obtaining healthcare reimbursements, which together with declining admission trends, could cause our sales to decline and negatively impact our business. For example, the margins of our hospital customers are modest, and potential decreases in reimbursement for healthcare costs may reduce the overall solvency of our customers or cause further deterioration in their financial or business condition.
In the past bills were signed into law that impact the U.S. healthcare system, including the ACA. Uncertainty surrounding the status of the ACA and its regulations may impact the spending of our healthcare customers, and we cannot predict the effect on our business of any new legislation and regulations that may be adopted if the ACA is significantly changed or repealed or of additional regulations.
Federal budget activities also impact our customers. Our customers include healthcare facilities run by the Department of Defense and the U.S. Department of Veterans Affairs. During the years ended December 31, 2021, 2020 and 2019, we generated approximately 20%, 18% and 17%, respectively, of our revenue from these customers. Our reseller to the Department of Defense and the U.S. Department of Veterans Affairs represented 17% and 33% of our accounts receivable as of December 31, 2021 and 2020, respectively. These customers have been and may continue to be impacted by budgetary and legislative actions.
In the past certain departments of the U.S. federal government temporarily stopped operating as a result of failure by the legislative and executive branches of the government to pass bills to keep them operating. In the current political climate there is a risk that the government could be shut down again. Any past or future shutdown may impact our US government customers’ spending decisions, as well as those of our non-US government customers. Any reduction or delay in our customers’, or potential customers’ spending decisions may result in a delay, or reduction, to our revenue.
22

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.

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

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

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

We rely on information technology and telephone networks and systems, including the Internet, to process and transmit sensitive electronic information and to manage or support a variety of business processes and activities, including sales, billing, customer service, procurement and our 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. In the ordinary course of our business, we also collect, store, process, use and transmit large amounts of confidential information, including intellectual property, protected health information, proprietary business information and personal information. 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. Most of our workforce is currently working remotely as a result of the COVID-19 pandemic, which also increases risks related to information security. Although we have developed systems and processes that are designed to protect confidential information and prevent data loss and other security breaches, including systems and processes designed to reduce the impact of a security breach, such measures cannot provide absolute security. The risk of a security breach or disruption or data loss, particularly through cyber-attacks or cyber intrusion, including by computer hackers, foreign governments and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. We may not be able to anticipate all types of security threats, and we may not be able to implement preventive measures effective against all such security threats. Although we maintain cybersecurity insurance, 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 beyond our insurance coverage. In addition, such a breach may require notification to governmental agencies, the media and/or affected individuals pursuant to various federal, state (including regulations promulgated by the Federal Trade Commission and state breach notification laws) and international privacy (including GDPR) and security laws, if applicable, including HIPAA or HITECH and its implementing rules and regulations. Security breaches could also cause us to incur significant remediation costs, result in product development delays, disrupt key business operations, adversely impact customer relationships, damage our reputation and divert attention of management and key information technology resources.

During fiscal year 2020, one of our vendors, SolarWinds, was the victim of a cyberattack that inserted a vulnerability in their platform. We use SolarWinds services for our internal corporate network so this introduced a potential vulnerability in our internal systems. We have removed the vulnerable software from our network and have not found any indication that the
23

vulnerability was exploited. There are still uncertainties about the full scope of this cyberattack and we may learn of other vulnerabilities and potential network intrusions by third parties.

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

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

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

We believe that a significant opportunity exists to continue to sell our products to healthcare facilities in the Veterans Administration and Department of Defense (DoD). These customers require independent certification of compliance with specific requirements relating to encryption, security, interoperability and scalability, including Federal Information Processing Standard (FIPS) 140-2 and, as to DoD, certification by its Joint Interoperability and Test Command and under its Information Assurance Certification and Accreditation Process. We have received certification under certain of these standards for military-specific configurations of our solution incorporating our Badge and Smartbadge. We continue to carry out further compliance activities and recertifications, as required. A failure on our part to achieve and maintain compliance and to respond to new threats and vulnerabilities, both as to current products and as to new product versions, could adversely impact our revenue.

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


Although we derive a relatively small portion of our revenue from customers outside the United States, we believe that non-U.S. customers could represent an increasing share of our revenue in the future. During the years ended December 31, 2017, 20162021, 2020 and 2015,2019, we generated 10.5%9.4%, 10.6%10.7% and 8.8%8.7% of our revenue, respectively, from customers outside of the United States, including Canada, the United Kingdom, Australia, New Zealand and Middle Eastern countries including the United Arab Emirates, Saudi Arabia and Qatar. In 2014, we opened a newWe also operate an 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 asif we expand into non-English speaking jurisdictions;markets;
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;

the impacts associated with epidemics or contagious diseases;
adverse effects on us directly, or on our customers and suppliers, of changes in trade, fiscal or tax policies;policies, including the imposition of tariffs;
difficulties in collecting accounts receivable and longer accounts receivable payment cycles;
exposure to competitors who are more familiar with local markets;
24

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

In recent years, we have actively engaged in sales efforts to customers outside the healthcare markets, including hospitality, retail, energy, education and other mobile work environments. We may not be successful in further penetrating the non-healthcare markets upon which we are highly complexinitially focusing, or other new markets. To date, our solutions have been selected by over 450 customers in non-healthcare markets. Total revenue from non-healthcare customers accounted for 2%, 2% and 4% of our revenue for the years ended December 31, 2021, 2020 and 2019, respectively. If we cannot maintain these customers by providing solutions that meet their requirements, if we cannot successfully expand our solutions in non-healthcare markets, or if adoption of our solutions remains slow, we may not obtain significant revenue from these markets. We may experience challenges as we expand in non-healthcare markets, including pricing pressure on our solutions, budget constraints, and technical issues as we adapt our solutions for the requirements of new markets. For example, some of our hospitality and retail customers have been significantly impacted by the COVID-19 pandemic and they have been forced to close locations and face significant revenue declines. Our solutions also may not contain softwarethe functionality required by these non-healthcare markets, may be too expensive or hardware defectsmay not sufficiently differentiate us from competing solutions such that could harmcustomers can justify deploying our reputationsolutions.

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.


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 andWe generally recognize revenue from our customer has commenced general use ofsubscription and support contracts and extended warranty contracts ratably over the solution.

Revenue from our subscription and software offeredsupport contracts accounted for 40%, 40% and 38% of our revenue for years ended December 31, 2021, 2020, and 2019, respectively. A portion of the revenue we report in each quarter is derived from the recognition of deferred revenue relating to subscription and support contracts entered into during previous quarters. Consequently, a decline in new or renewed subscription and support, extended warranty contracts or subscription agreements by “middleware” vendorsour customers in order to interoperate with nurse call systems, device alarms and other hospital systems.

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


In connection with our healthcare business, we handle and have access to personal health information“Protected Health Information” (PHI) subject in the United States to HIPAA or HITECH,the Health Insurance Portability and Accountability Act of 1996 (HIPAA) as amended and supplemented by the Health Information Technology for Economic and Clinical Health Act of 2009 (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 informationPHI with which we must comply. Among other things, HITECH made certain aspects of HIPAA’s rules, notably the “HIPAA Security Rule,” directly applicable to business associates, independent contractors or agents of covered entities that create, receive, maintain or transmit PHI in connection with providing a function on behalf of, or a service to, a covered entity (e.g., health care communication solutions). HITECH also created four new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates and gave state attorneys general new authority to file civil actions for damages or injunctions in federal court to enforce the federal HIPAA regulation and seek attorney’s fees and costs associated with pursuing federal civil actions. The U.S. Department of Health & Human Services Office for Civil Rights (OCR) has increased its focus on compliance and continues to train state attorneys general for enforcement purposes. The OCR has recently increased both its efforts to audit HIPAA compliance and its level of enforcement, with one recent penalty exceeding $16 million. 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.
25

In addition, the use and disclosure of personal health information, non-health personal information is also 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 (including but not limited to regulatory enforcement actions), which may 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. Inin May 2016, the EU formally adopted the General Data Protection Regulation (GDPR), which will applybecame effective in May 2018. The GDPR greatly increased the European Commission’s jurisdictional reach of its laws and adds a broad array of requirements for handling personal information, including, for example, requirements to allestablish a legal basis for processing, higher standards for obtaining consent from individuals to process their personal information, more robust disclosures to individuals and a strengthened individual data rights regime, requirements to implement safeguards to protect the security and confidentiality of personal information that requires the adoption of administrative, physical and technical safeguards, shortened timelines for data breach notifications to appropriate data protection authorities or data subjects, limitations on retention and secondary use of information, increased requirements pertaining to health data and additional requirements that we impose certain contractual obligations on third-party processors in connection with the processing of the personal information. EU member states beginningare tasked under the GDPR to enact, and have enacted, certain implementing legislation that adds to and/or further interprets the GDPR requirements and potentially extends our obligations and potential liability for failing to meet such obligations. The GDPR, together with national legislation, regulations and guidelines of the EU member states governing the processing of personal information, impose strict obligations and restrictions on the ability to collect, use, retain, protect, disclose, transfer and otherwise process personal information. In particular, the GDPR includes obligations and restrictions concerning the consent and rights of individuals to whom the personal information relates, the transfer of personal information out of the European Economic Area, security breach notifications and the security and confidentiality of personal information. The GDPR authorizes fines for certain violations of up to 4% of global annual revenue or €20 million, whichever is greater, and other administrative penalties. Additionally, the United Kingdom (UK) implemented the Data Protection Act effective in May 2018 and will replacestatutorily amended in 2019, that substantially implements the current DPD.GDPR and contains provisions, including UK-specific derogations, for how GDPR is applied in the UK. Since the beginning of 2021 (when the transitional period following Brexit expired), we also have to continue to comply with the GDPR and the Data Protection Act, with each regime having the ability to fine up to the greater of €20 million (£17 million) or 4% of global revenue. The regulation introduces newrelationship between the UK and the EU remains uncertain, for example how data protection requirements intransfers between the UK and the EU and substantial fines for breachesother jurisdictions will be treated and the role of the UK’s supervisory authority. For example, on June 28, 2021, the European Commission adopted the adequacy decision (the “UK Adequacy Decision”) in the wake of a non-binding vote by the European Parliament against the then-draft UK Adequacy Decision the month prior. Consequently, personal data can continue to flow from the EEA to the UK without the need for appropriate safeguards. The UK Adequacy Decision includes a “sunset clause”, rendering the decision valid for four years only, after which it will be reviewed by the European Commission and renewed only if the European Commission considers that the UK continues to ensure an adequate level of data protection. The European Commission also stated that it would intervene at any point within the four years if the UK deviates from the level of protection rules. Itpresently in place. If this adequacy decision reversed by the European Commission, it would require that companies implement protection measures such as the standard contractual clauses, or “Standard contractual Clauses,” for data transfers between the EU and the UK. These changes will lead to additional costs as we try to ensure compliance with new privacy legislation and will increase our responsibility and liability in relation to personal data that we process and we may be required to put in place additional mechanisms ensuringoverall risk exposure.
The costs of compliance with, the new EU data protection rules.  Additionally, Canada’s Personal Information and Protection of Electronic Documents Act, as well as a variety of provincial

statutes, provides Canadian residents with privacy protections in regard to transactions with businesses and organizations in the private sector and sets out ground rules for how private sector organizations may collect, use and disclose personal information in the course of commercial activities. A finding that we have failed to comply with applicableother burdens imposed by, such laws and regulations regardingthat are applicable to our business operations may limit the collection, use and disclosureadoption of personal informationour services and reduce overall demand for them. Changes in these legislations may add additional complexity, variation in requirements, restrictions and potential legal risk, require additional investment in resources for compliance programs, could create liability for us,impact strategies and availability of previously useful data, and could result in adverse publicityincreased compliance costs and/or changes in business practices and negatively affect our business.policies.
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 EuropeanGDPR imposes strict rules on the transfer of personal information out of the EU to the United States. These obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other requirements or our practices. In addition, these rules are consistently under scrutiny. For example, on July 16, 2020, the Court of Justice of the European Union (the Court of Justice) invalidated the U.S.-EU Safe Harbor frameworkEuropean Union-United States (EU-U.S.) Privacy Shield on the grounds that had beenthe EU-U.S. Privacy Shield failed to offer adequate protections to EU personal information transferred to the United States. While the Court of Justice upheld the use of other data transfer mechanisms, such as the Standard Contractual Clauses, the decision has led to some uncertainty regarding the use of such mechanisms for data transfers to the United States, and the court made clear that reliance on Standard Contractual Clauses alone may not necessarily be sufficient in place since 2000, which allowed companies to meet certain EU legal requirementsall circumstances. The use of Standard Contractual Clauses for the transfer of personal information specifically to the United States also remains under review by a number of European data protection supervisory authorities. For example, German and Irish supervisory authorities have indicated that the Standard Contractual Clauses alone provide inadequate protection for EU-U.S. data transfers. Use of the data transfer mechanisms must
26

now be assessed on a case-by-case basis taking into account the legal regime applicable in the destination country, in particular applicable surveillance laws and rights of individuals.
On June 4, 2021, the European Commission finalized new versions of the Standard Contractual Clauses, with the implementing decision, or “Implementing Decision,” now in effect as of June 27, 2021. Under the Implementing Decision, the revised clauses must be used for relevant new data transfers from September 27, 2021 and existing standard contractual clauses arrangements must be migrated to the revised clauses by December 27, 2022. To comply with the Implementing Decision and the new Standard Contractual Clauses, we may need to implement additional safeguards to further enhance the security of data transferred out of the European Economic Area, which could increase our compliance costs, expose us to further regulatory scrutiny and liability, and adversely affect our business.
Additionally, other countries (e.g., Australia and Japan) have adopted certain legal requirements for cross-border transfers of personal information. These obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other requirements or our practices. Further, since the transition period for Brexit ended December 31, 2020, there remains some uncertainty regarding cross-border data transfers from the EU to the United States. While other adequate legal mechanisms to lawfully transfer such data remain,Kingdom following 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.June 2021 UK Adequacy Decision. 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. If we are required to implement additional measures to transfer data from foreign jurisdictions, such as the EU, this could increase our compliance costs, and could adversely affect our business, financial condition and results of operations. Further, we cannot assure youguarantee 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.

Additionally, several states have begun enacting new data privacy laws. For example, California recently enacted legislation, the California Consumer Privacy Act (CCPA), that, among other things, requires covered companies to provide new disclosures to California consumers, and afford such consumers new abilities to opt out of certain sales of personal information. The CCPA took effect on January 1, 2020 and became enforceable by the California Attorney General on July 1, 2020. The CCPA has been amended on multiple occasions and additional regulations of the California Attorney General came into effect on August 14, 2020 and were most recently amended on March 15, 2021. However, aspects of the CCPA and its interpretation remain unclear. The effects of the CCPA are significant and may require us to modify our data processing practices and policies and to incur substantial costs and expenses in an effort to comply. Moreover, a new privacy law, the California Privacy Rights Act (CPRA) was recently approved by California voters in connection with the election on November 3, 2020. The CPRA creates obligations relating to consumer data beginning on January 1, 2022, with implementing regulations expected on or before July 1, 2022, and enforcement beginning July 1, 2023. The CCPA requires (and the CPRA will require) covered companies to, among other things, provide new disclosures to California consumers, and affords such consumers new privacy rights such as the ability to opt-out of certain sales of personal information and expanded rights to access and require deletion of their personal information, opt out of certain personal information sharing, and receive detailed information about how their personal information is collected, used and shared. The CCPA provides for civil penalties for violations, as well as a private right of action for security breaches that may increase security breach litigation. Potential uncertainty surrounding the CCPA and CPRA may increase our compliance costs and potential liability, particularly in the event of a data breach, and could have a material adverse effect on our business, including how we use personal information, our financial condition, the results of our operations or prospects. The CCPA has also prompted a number of proposals for new federal and state privacy legislation that, if passed, could increase our potential liability, increase our compliance costs and adversely affect our business. Two states have recently passed personal information laws: the Colorado Privacy Act, which goes into effect on July 1, 2023; and Virginia’s Consumer Data Protection Act, which goes into effect on January 1, 2023.
The interplay of federal and state laws (e.g., in addition to California, Massachusetts and Nevada have adopted laws requiring the implementation of certain security measures to protect personal information, and all 50 states and the District of Columbia, Puerto Rico and Guam, have adopted breach notification laws) may be subject to varying interpretations by courts and government agencies, creating complex compliance issues for us and our customers and potentially exposing us to additional expense, adverse publicity and liability. Further, as regulatory focus on privacy, security and data use issues continues to increase and laws and regulations concerning the protection of personal information expand and become more complex, these potential risks to products and services could intensify.
As mentioned, changing definitions of personal data and information may also limit or inhibit our ability to operate or expand our business, including limiting strategic partnerships that may involve the sharing of data. Also, some jurisdictions require that certain types of data be retained on servers within these jurisdictions. Our failure to comply with applicable laws, directives, and regulations may result in enforcement action against us, including fines, and damage to our reputation, any of which may have an adverse effect on 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 revenuebusiness and operating results.


In 2012, we began offering our solutions to our customers through multi-year equipment lease agreements. In connection with each sale, we recognize product-related revenue at the net present value
27


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.customers, including personal information and PHI. We have implemented programs to detect and alert us to data security incidents. However, because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and may be difficult to detect for long periods of time, we may be unable to anticipate these techniques or implement adequate preventive measures. Companies are increasingly subject to a wide variety of security incidents, cyber-attacks and other attempts to gain unauthorized access. These threats can come from a variety of sources, ranging in sophistication from an individual hacker to malfeasance by employees, consultants or other service providers to state-sponsored attacks. Cyber threats may be generic, or they may be custom-craftedcustom 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.litigation, as well as potentially incur significant costs and diversion of resources to comply with our contractual obligations to notify our customers of such security breaches, particularly with respect to any protected health information affected. Moreover, if a computer security breach affects our systems or results in the unauthorized access, use or disclosure of personal information, our reputation could be materially damaged. In addition, such a breach may require notification to governmental agencies, the media and/or affected individuals pursuant to various federal, state and international privacy and security laws, if applicable, including HIPAA or HITECH and its implementing rules and regulations, as well as regulations promulgated by the Federal Trade Commission and state breach notification laws. We would also be exposed to a risk of loss or litigation and potential liability under laws, regulations and contracts that protect the privacy and security of personal information. For example, as stated above, the CCPA imposes a private right of action for security breaches that could lead to some form of remedy including regulatory scrutiny, fines, private right of action settlements, and other consequences. The financial exposure from the events referenced above could either not be insured against or not be fully covered through any insurance that we may maintain, and there can be no assurance that the limitations of liability in any of our contracts would be enforceable or adequate or would otherwise protect us from liabilities or damages as a result of the events referenced above. Any of the foregoing could have a material adverse effect on our business, reputation, results of operations, financial condition and prospects. 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.


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

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

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
28

from alternative licensors, which may not be available on a commercially reasonable basis or at all, to re-engineer our solutions or to discontinue the sale of our solutions in the event we cannot obtain a license or re-engineer our solutions on a timely basis, any of which could harm our business and operating results. In addition, if an owner of licensed software were to allege that we had not complied with the conditions of the corresponding license agreement, we could incur significant legal costs defending ourselves against such allegations. In the event such claims were successful, we could be subject to significant damages, be required to disclose our source code, or be enjoined from the distribution of our solutions.


Claims of intellectual property infringement could harm our business.


Vigorous protection and pursuit of intellectual property rights has resulted in protracted and expensive litigation for many companies in our industry. Although claims of this kind have not materially affected our business to date, there can be no assurance of the absence of such claims in the future. Any claims or proceedings against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time, result in the diversion of significant operational resources, or require us to enter into royalty or licensing agreements, any of which could harm our business and operating results.
Intellectual property lawsuits are subject to inherent uncertainties due to the complexity of the technical issues involved, and we cannot be certain that we will be successful in defending ourselves against intellectual property claims. In addition, we currently have a limited portfolio of issued patents compared to many other industry participants, and therefore may not be able to effectively utilize our intellectual property portfolio to assert defenses or counterclaims in response to patent infringement claims or litigation brought against us by third parties. Further, 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.
29

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


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


Our solutions are utilized by healthcare professionals and others in the course of providing patient care. As a result, patients, family members, physicians, nurses or others may allege we are responsible for harm to patients or healthcare professionals due to defects in, the malfunction of, the characteristics of, or the operation of, our solutions. Any such allegations could harm our reputation and ability to sell our solutions. For example, we are currently a defendant, along with several other healthcare and equipment providers, in a litigation involving the death of a patient undergoing surgery at a hospital of one of our customers. The Company plans to defend itself vigorously in this matter, but the outcome of any litigation is inherently uncertain.
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 badgesBadges may emit electromagnetic radiation and may be alleged to interfere with implanted medical or other devices. While these components of our solutions comply with applicable guidelines, some may allege that these components of our solutions cause adverse health consequences. Also, applicable guidelines may change making these components of our solutions non-compliant. Any such allegations or non-compliance, or any regulatory developments, could negatively impact the sales of our solutions, require costly modifications to our solutions, and harm our reputation.
Although our customer agreements contain terms and conditions, including disclaimers of liability, that are intended to reduce or eliminate our potential liability, we could be required to spend significant amounts of management time and resources to defend ourselves against product liability, tort, warranty or other claims. If any such claims were to prevail, we could be forced to pay damages, comply with injunctions or stop distributing our solutions. Even if potential claims do not result in liability to us, investigating and defending against these claims could be expensive and time consuming and could divert management’s attention away from our business. We maintain general liability insurance coverage, including coverage for errors and omissions; however, this coverage may not be sufficient to cover large claims against us or otherwise continue to be available on acceptable terms. Further, the insurer could attempt to disclaim coverage as to any particular claim.


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


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


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


We provide certain products that are, and others that may become, subject to regulation by the FDAFood and Drug Administration (FDA) and similar agencies in other countries, or the jurisdiction of these agencies could be expanded in the future to include our solutions. The FDA regulates certain products, including software-based products, as “medical devices” based, in part, on the intended use of the product and the risk the device poses to the patient should the device fail to perform properly. For example, the clinical alert notification solution we acquired as part of our acquisition of Extension Healthcare and the clinical communications product we acquired from mVisum are regulated by the FDA as Class II medical devices. Although we have concluded that our wireless badgeBadge 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
30

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. The clinical alert notification solution

Environmental and social (E&S) regulations, policies and provisions, as well as customer demand, may make our supply chain more complex and may adversely affect our relationships with customers.

There is an increasing focus on the governance of environmental and social risks in our industry. A number of our customers have adopted, or may adopt, procurement policies that include E&S provisions that their suppliers must comply with, or they may seek to include such provisions in their procurement terms and conditions. An increasing number of participants in the industry are also joining voluntary E&S initiatives, such as the Responsible Business Alliance. These E&S provisions and initiatives are subject to change, can be unpredictable, and may be difficult and expensive for us to comply with, given the complexity of our supply chain and our outsourced manufacturing. If we acquiredare unable to comply or are unable to cause our suppliers or contract manufacturers to comply, with such policies or provisions, a customer may stop purchasing products from us, and may take legal action against us, which could harm our reputation, revenue and results of operations.

In addition, as part of their E&S programs, an increasing number of customers are seeking to source products that do not contain minerals sourced from areas where proceeds from the sale of such minerals are likely to be used to fund armed conflict, such as in the Democratic Republic of the Congo. This could adversely affect the sourcing, availability and pricing of minerals used in the manufacture of our acquisitionequipment. Since our supply chain is complex, we are not currently able to definitively ascertain the origins of Extension Healthcareall of the minerals and metals used in our products. As a result, we may face difficulties in satisfying these customers’ demands, which may harm our sales and operating results.

Risks Related to our Notes

We have indebtedness in the form of convertible senior notes.

As a result of the Notes offerings, we incurred $265.3 million principal amount of indebtedness, the principal amount of which we may be required to pay at maturity in 2023 and 2026. Holders of the Notes will have the right to require us to repurchase their Notes upon the occurrence of a “fundamental change” (as defined in the indenture governing the Notes) at a purchase price equal to 100% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest, if any. In addition, the indenture for the Notes provides that we are required to repay amounts due under the indenture in the event that there is an event of default for the Notes that results in the principal, premium, if any, and interest, if any, becoming due prior to maturity date of the Notes. There can be no assurance that we will be able to repay this indebtedness when due, or that we will be able to refinance this indebtedness on acceptable terms or at all. In addition, this indebtedness could, among other things:

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

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

Although the Notes are referred to as convertible senior notes, they are effectively subordinated to any of our secured debt and any liabilities of our subsidiaries.

The Notes rank senior in right of payment to any of our indebtedness that is expressly subordinated in right of payment to the Notes; equal in right of payment to all of our existing and future liabilities that are not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all indebtedness and other liabilities (including trade payables) of our current or future subsidiaries. In the
31

event of our bankruptcy, liquidation, reorganization, or other winding up, our assets that secure debt ranking senior or equal in right of payment to the Notes will be available to pay obligations on the Notes only after the secured debt has been repaid in full from these assets, and the clinical communications productassets of our subsidiaries will be available to pay obligations on the Notes only after all claims senior to the Notes have been repaid in full. There may not be sufficient assets remaining to pay amounts due on any or all of the Notes then outstanding. The indentures governing the Notes do not prohibit us from incurring additional senior debt or secured debt, nor do they prohibit any of our current or future subsidiaries from incurring additional liabilities.

Servicing our debt requires, and will require, a significant amount of cash. We may not have sufficient cash flow to make payments on our debt, which could adversely affect our business, financial condition and results of operations.

Our ability to make scheduled payments of the principal of, to pay interest on or to refinance our indebtedness, including the Notes, depends on our future performance, which is subject to economic, financial, competitive and other factors beyond our control. Our business may not continue to generate cash flow from operations in the future sufficient to service our debt and make necessary capital expenditures. If we acquired from mVisum are regulatedunable to generate such cash flow, we may be required to adopt one or more alternatives, such as selling assets, restructuring debt or obtaining additional equity capital on terms that may be onerous or highly dilutive. Our ability to refinance our indebtedness will depend on the capital markets and our financial condition at such time. We may not be able to engage in any of these activities or engage in these activities on desirable terms, which could result in a default on our debt obligations, including the Notes or otherwise.

In addition, our significant indebtedness, combined with our other financial obligations and contractual commitments, could have other important consequences. For example, it could:

make us more vulnerable to adverse changes in general U.S. and worldwide economic, industry and competitive conditions and adverse changes in government regulation;
limit our flexibility in planning for, or reacting to, changes in our business and our industry;
place us at a disadvantage compared to our competitors who have less debt; and
limit our ability to borrow additional amounts for working capital and other general corporate purposes, including to fund possible acquisitions of, or investments in, complementary businesses, products, services and technologies.

Any of these factors could materially and adversely affect our business, financial condition and results of operations. In addition, if we incur additional indebtedness, the risks related to our business and our ability to service or repay our indebtedness would increase.

Recent and future regulatory actions and other events may adversely affect the trading price and liquidity of the Notes.

We expect that many investors in, and purchasers of, the Notes will employ, or seek to employ, a convertible arbitrage strategy with respect to the Notes. Investors would typically implement such a strategy by selling short the common stock underlying the notes and dynamically adjusting their short position while continuing to hold the notes. Investors may also implement this type of strategy by entering into swaps on our common stock in lieu of or in addition to short selling the common stock.

The SEC and other regulatory and self-regulatory authorities have implemented various rules and taken certain actions, and may in the future adopt additional rules and take other actions, that may impact those engaging in short selling activity involving equity securities (including our common stock). Such rules and actions include Rule 201 of SEC Regulation SHO, the adoption by the FDAFinancial Industry Regulatory Authority, Inc. and the national securities exchanges of a “Limit Up-Limit Down” program, the imposition of market-wide circuit breakers that halt trading of securities for certain periods following specific market declines, and the implementation of certain regulatory reforms required by the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Any governmental or regulatory action that restricts the ability of the holders the Notes to effect short sales of our common stock, borrow our common stock, or enter into swaps on our common stock could adversely affect the trading price and the liquidity of the Notes.

Volatility in the market price and trading volume of our common stock could adversely impact the trading price of the Notes.

We expect that the trading price of the Notes will be significantly affected by the market price of our common stock. The stock market in recent years has experienced significant price and volume fluctuations that have often been unrelated to the operating performance of companies. The market price of our common stock could fluctuate significantly for many reasons. A decrease in the market price of our common stock would likely adversely impact the trading price of the Notes. The market price of our common stock could also be affected by possible sales of our common stock by investors who view the Notes as Class II medical devices.a more attractive means of equity participation in us and by hedging or arbitrage trading activity that we expect to develop involving our common stock. This trading activity could, in turn, affect the trading price of the Notes.

32


We may still incur substantially more debt or take other actions which would intensify the risks discussed above.

We and our subsidiaries may incur substantial additional debt in the future, subject to the restrictions contained in our debt instruments, some of which may be secured debt. We will not be restricted under the terms of the indentures governing the Notes from incurring additional debt, securing existing or future debt, recapitalizing our debt, or taking a number of other actions that are not limited by the terms of the indentures governing the Notes that could have the effect of diminishing our ability to make payments on our debt, including the Notes, when due.

We may not have the ability to raise the funds necessary to settle conversions of the Notes in cash or to repurchase the Notes upon a fundamental change, and our future debt may contain limitations on our ability to pay cash upon conversion or repurchase of the Notes.

Holders of the Notes will have the right, subject to certain conditions and limited exceptions, to require us to repurchase all or a portion of their Notes upon the occurrence of a fundamental change before the maturity date at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest, if any, In addition, upon conversion of the Notes, unless we elect to deliver solely shares of our common stock to settle such conversion (other than paying cash in lieu of delivering any fractional share), we will be required to make cash payments in respect of the Notes being converted. However, we may not have enough available cash or be able to obtain financing at the time we are required to make repurchases of the Notes surrendered therefor or pay cash with respect to Notes being converted.

In addition, our ability to repurchase Notes or to pay cash upon conversions of the Notes may be limited by law, regulatory authority, or any agreements governing our future indebtedness. Our failure to repurchase Notes at a time when the repurchase is required by the indenture or to pay any cash upon conversions of the Notes as required by the indenture would constitute a default under the indenture. A default under the indenture or the fundamental change itself could also lead to a default under agreements governing our future indebtedness. If the payment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Notes or to pay cash upon conversions of the notes.

Redemption may adversely affect a holder’s return on the 2026 Notes.

We may not redeem the 2026 Notes prior to March 20, 2024. We may redeem for cash all or any portion of the 2026 Notes (subject to the partial redemption limitation (as defined in the indenture governing the notes)), at our option, on or after March 20, 2024 if the last reported sale price of our common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. As a result, we may choose to redeem some or all of the 2026 Notes, including at times when prevailing interest rates are relatively low. As a result, you may not be able to reinvest the proceeds you receive from the redemption in a comparable security at an effective interest rate as high as the interest rate on your 2026 Notes being redeemed. In addition, a redemption of less than all of the outstanding 2026 Notes will likely harm the liquidity of the market for the unredeemed 2026 Notes following the redemption. Accordingly, if your 2026 Notes are not redeemed in a partial redemption, then you may be unable to sell your 2026 Notes at the times you desire or at favorable prices, if at all, and the trading price of your 2026 Notes may decline.

The conditional conversion feature of the Notes, if triggered, may adversely affect our financial condition and operating results

In the event the conditional conversion feature of the Notes is triggered, holders of the Notes will be entitled to convert their Notes at any time during specified periods at their option. If one or more holders elect to convert their Notes, unless we elect to satisfy our conversion obligation by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share), we would be required to settle a portion or all of our conversion obligation through the payment of cash, which could adversely affect our liquidity. In addition, even if holders of the Notes do not elect to convert their Notes, we could be required under applicable accounting rules to reclassify all or a portion of the outstanding principal of the Notes as a current rather than long-term liability, which would result in a material reduction of our net working capital.

During the year ended December 31, 2021, the conditions allowing holders of the 2023 Notes to convert have been met because our stock price traded above the minimum price specified in the Indenture during the year ended December 31, 2021. The 2023
33

Notes are convertible at the option of the holder until at least March 31, 2022 and are classified as current debt as of December 31, 2021.

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

The accounting method for reflecting the Notes on our balance sheet, accruing amortized interest expense for the Notes and reflecting the underlying shares of our common stock in our reported diluted earnings per share may adversely affect our reported earnings and financial condition. For the fiscal year beginning January 1, 2021, we have elected to early adopt new accounting guidance that was recently released that simplifies the accounting for convertible debt that may be settled in cash (ASU 2020-06), amending Accounting Standards Codification 470-20, Debt with Conversion and Other Options (ASC 470-20). As a result, we recorded the convertible debt securities (including the Notes) entirely as a liability on our balance sheet, net of issuance costs incurred, with interest expense reflecting the cash coupon plus the amortization of the capitalized issuance costs. Additionally, the new guidance modifies the treatment of convertible debt securities that may be settled in cash or shares by requiring the use of the “if-converted” method. Under that method, diluted earnings per share would generally be calculated assuming that all the Notes were converted solely into shares of common stock at the beginning of the reporting period, unless the result would be antidilutive. In addition, in the future, we may, in our sole discretion, irrevocably elect to settle the conversion value of the Notes in cash up to the principal amount being converted. Following such an irrevocable election, we will calculate our diluted earnings per share by assuming that all of the Notes were converted at the beginning of the reporting period and that we issued shares of our common stock to settle the excess, unless the result would be anti-dilutive. The application of the if-converted method may reduce our reported diluted earnings per share. Furthermore, if any of the conditions to the convertibility of the Notes are satisfied, then, under certain conditions, we may be required under applicable accounting standards to reclassify the liability carrying value of the Notes as a current, rather than a long-term, liability. This reclassification could be required even if no noteholders convert their Notes and could materially reduce our reported working capital.

Future sales of our common stock or equity-linked securities in the public market could lower the market price for our common stock and adversely impact the trading price of the Notes.

In the future, we may sell additional shares of our common stock or equity-linked securities to raise capital. In addition, a substantial number of shares of our common stock is reserved for issuance upon the exercise of stock options and upon conversion of the Notes. We cannot predict the size of future issuances or the effect, if any, that they may have on the market price for our common stock. The issuance and sale of substantial amounts of our common stock or equity-linked securities, or the perception that such issuances and sales may occur, could adversely affect the trading price of the Notes and the market price of our common stock and impair our ability to raise capital through the sale of additional equity or equity-linked securities.

Holders of the Notes will not be entitled to any rights with respect to our common stock, but they will be subject to all changes affecting our common stock to the extent satisfaction of our conversion obligation includes shares of our common stock.

Holders of the Notes will not be entitled to any rights with respect to our common stock (including, without limitation, voting rights and rights to receive any dividends or other distributions on our common stock) prior to the conversion date relating to such Notes (if we have elected to settle the relevant conversion by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share)) or the last trading day of the relevant observation period (if we elect to pay and deliver, as the case may be, a combination of cash and shares of our common stock in respect of the relevant conversion), but holders of the Notes will be subject to all changes affecting our common stock. For example, if an amendment is proposed to our restated certificate of incorporation or restated bylaws requiring stockholder approval and the record date for determining the stockholders of record entitled to vote on the amendment occurs prior to the conversion date related to a holder’s conversion of its Notes (if we have elected to settle the relevant conversion by delivering solely shares of our common stock (other than paying cash in lieu of delivering any fractional share)) or the last trading day of the relevant observation period (if we elect to pay and deliver, as the case may be, a combination of cash and shares of our common stock in respect of the relevant conversion), such holder will not be entitled to vote on the amendment, although such holder will nevertheless be subject to any changes affecting our common stock.

34

The conditional conversion feature of the Notes could result in holders of our Notes receiving less than the value of our common stock into which the Notes would otherwise be convertible.

Prior to the close of business on the business day immediately preceding June 15, 2026, a holder may convert 2026 Notes only if specified conditions are met. If the specific conditions for conversion are not met, a holder will not be able to convert 2026 Notes, and a holder may not be able to receive the value of the cash, common stock or a combination of cash and common stock, as applicable, into which the 2026 Notes would otherwise be convertible.

Upon conversion of the Notes, our Note holders may receive less valuable consideration than expected because the value of our common stock may decline after the exercise of conversion rights but before we settle our conversion obligation.

Under the Notes, a converting holder will be exposed to fluctuations in the value of our common stock during the period from the date such holder surrenders Notes for conversion until the date we settle our conversion obligation. For example, upon conversion of the 2026 Notes, we have the option to pay or deliver, as the case may be, cash, shares of our common stock, or a combination of cash and shares of our common stock. If we elect to satisfy our conversion obligation in cash or a combination of cash and shares of our common stock, the amount of consideration that our Note holders will receive upon conversion of their 2026 Notes will be determined by reference to the volume weighted average prices of our common stock for each trading day in a 40 trading day observation period. This period would be: (i), subject to clause (ii), if the relevant conversion date occurs prior to June 15, 2026, the 40 consecutive trading days beginning on, and including, the second trading day immediately succeeding such conversion date; (ii) with respect to any 2026 Notes called for redemption (or deemed called for redemption) and prior to the relevant redemption date, the 40 consecutive trading days beginning on, and including the 41st scheduled trading day immediately preceding such redemption date; and (iii) subject to clause (ii) if the relevant conversion date occurs on or after June 15, 2026, the 40 consecutive trading days beginning on, and including, the 41st scheduled trading day immediately preceding the maturity date. Accordingly, if the price of our common stock decreases during this period, the amount and/or value of consideration a Note holder receives will be adversely affected. In addition, if the market price of our common stock at the end of such period is below the average of the daily volume weighted average prices of our common stock during such period, the value of any shares of our common stock that a Note holder will receive in satisfaction of our conversion obligation will be less than the value used to determine the number of shares that the Note holder will receive. If we elect to satisfy our conversion obligation solely in shares of our common stock upon conversion of the 2026 Notes, we will be required to deliver the shares of our common stock, together with cash for any fractional share, on the second business day following the relevant conversion date. Accordingly, if the price of our common stock decreases during this period, the value of the shares that a Note holder receives will be adversely affected and would be less than the conversion value of the 2026 Notes on the conversion date.

The Notes are not protected by restrictive covenants.

The indentures governing the Notes do not contain any financial or operating covenants or restrictions on the payments of dividends, the incurrence of indebtedness, or the issuance or repurchase of securities by us or any of our subsidiaries. The indentures do not contain any covenants or other provisions to afford protection to holders of the Notes in the event of a fundamental change or other corporate transaction involving us except to the extent described in the indentures governing the Notes.

The increase in the conversion rate for Notes converted in connection with a make-whole fundamental change or a notice of redemption may not adequately compensate Note holders for any lost value of their Notes as a result of such transaction or redemption.

If a make-whole fundamental change occurs prior to the maturity date or if we deliver a notice of redemption, we will, under certain circumstances, increase the conversion rate by a number of additional shares of our common stock for Notes converted in connection with such make-whole fundamental change or Notes called (or deemed called) for redemption that are converted during the related redemption period. The increase in the conversion rate will be determined based on the date on which the make-whole fundamental change occurs or the date we deliver the notice of redemption, as the case may be, and the price paid (or deemed to be paid) per share of our common stock in the make-whole fundamental change or determined with respect to the notice of redemption, as the case may be. The increase in the conversion rate for Notes converted in connection with a make-whole fundamental change or called (or deemed called) for redemption that are converted during the related redemption period may not adequately compensate a Note holder for any lost value of the Notes as a result of such transaction or redemption. Furthermore, if we call only a portion of the outstanding Notes for redemption, only those Notes called (or deemed called) for redemption will become convertible as a result of such call for redemption and only the conversion rate of the Notes converted in connection with such notice of redemption will be increased. Accordingly, Notes not called for redemption will not become
35

convertible if not otherwise convertible at such time and will remain outstanding, and may have reduced liquidity and a resulting reduced trading price.

In addition, for the 2026 Notes, if the price per share of our common stock is greater than $325.00 per share or less than $44.55 per share (in each case, subject to adjustment), no additional shares will be added to the conversion rate. Moreover, in no event will the conversion rate per $1,000 principal amount of 2026 Notes as a result of this adjustment exceed 22.4466 shares of common stock, subject to adjustment. The 2023 Notes contain substantially similar conversion features.

Our obligation to increase the conversion rate for Notes converted in connection with a make-whole fundamental change or Notes called (or deemed called) for redemption that are converted during the related redemption period could be considered a penalty, in which case the enforceability thereof would be subject to general principles of reasonableness and equitable remedies.

The conversion rate of the Notes may not be adjusted for all dilutive events.

The conversion rate of the Notes is subject to adjustment for certain events, including, but not limited to, the issuance of certain stock dividends on our common stock, the issuance of certain rights or warrants, subdivisions, combinations, distributions of capital stock, indebtedness, or assets, cash dividends, and certain issuer tender or exchange offers. However, the conversion rate will not be adjusted for other events, such as a third-party tender or exchange offer or an issuance of our common stock for cash, that may adversely affect the trading price of the Notes or our common stock. An event that adversely affects the value of the Notes may occur, and that event may not result in an adjustment to the conversion rate.

Provisions in the indentures for the Notes may deter or prevent a business combination that may be favorable to our security holders.

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

Some significant restructuring transactions may not constitute a fundamental change, in which case we would not be obligated to offer to repurchase the Notes.

Upon the occurrence of a fundamental change, our Note holders have the right to require us to repurchase all or a portion of their Notes. However, the fundamental change provisions will not afford protection to holders of the Notes in the event of other transactions that could adversely affect the Notes. For example, a significant change in the composition of our board of directors or transactions such as leveraged recapitalizations, refinancings, restructurings, or acquisitions initiated by us may not constitute a fundamental change requiring us to offer to repurchase the Notes. In the event of any such transaction, the holders would not have the right to require us to repurchase the Notes, even though each of these transactions could increase the amount of our indebtedness, or otherwise adversely affect our capital structure or any credit ratings, thereby adversely affecting the holders of the Notes.

We have not registered, and are not required to register, the Notes or the common stock issuable upon conversion of the Notes, if any, which will limit our Note holders’ ability to resell them.

The Notes and the shares of common stock issuable upon conversion of the Notes, if any, have not been, and are not required to be, registered under the Securities Act or any state securities laws. Unless the Notes and any shares of common stock issuable upon conversion of the Notes, if any, have been registered, the Notes and such shares may not be transferred or resold except in a transaction exempt from or not subject to the registration requirements of the Securities Act and applicable state securities laws. We do not intend to file a registration statement for the resale of the Notes and the common stock, if any, into which the Notes are convertible.

We cannot assure you that an active trading market will develop for the Notes.

We do not intend to apply to list the Notes on any securities exchange or to arrange for quotation on any automated dealer quotation system. The liquidity of the trading market in the Notes, and the market price quoted for the Notes, may be adversely
36

affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry generally. As a result, an active trading market may not develop for the Notes. If an active trading market does not develop or is not maintained, the market price and liquidity of the Notes may be adversely affected. In that case Note holders may not be able to sell their Notes at a particular time or may not be able to sell their Notes at a favorable price.

Any adverse rating of the Notes may cause their trading price to fall.

We do not intend to seek a rating on the Notes. However, if a rating service were to rate the Notes and if such rating service were to lower its rating on the Notes below the rating initially assigned to the Notes or otherwise announces its intention to put the Notes on credit watch, the trading price of the Notes could decline.

Note holders may be subject to tax if we make or fail to make certain adjustments to the conversion rate of the Notes even though they do not receive a corresponding cash distribution.

The conversion rate of the Notes is subject to adjustment in certain circumstances, including the payment of cash dividends. If the conversion rate is adjusted as a result of a distribution that is taxable to our common stockholders, such as a cash dividend, Note holders may be deemed to have received a dividend subject to U.S. federal income tax without the receipt of any cash. In addition, a failure to adjust (or to adjust adequately) the conversion rate after an event that increases a Note holder’s proportionate interest in us could be treated as a deemed taxable dividend to the holder. If a make-whole fundamental change occurs prior to the maturity date or if we deliver a notice of redemption, we will, under some circumstances, increase the conversion rate for Notes converted in connection with the make-whole fundamental change or called (or deemed called) for redemption that are converted during the related redemption period. Such increase may also be treated as a distribution subject to U.S. federal income tax as a dividend. If a Note holder is a non-U.S. holder, any deemed dividend would generally be subject to U.S. federal withholding tax, which may be set off against subsequent payments on the Notes or other amounts received by the holder.

Because the Notes are held in book-entry form, holders must rely on The Depository Trust Company (DTC) procedures to receive communications relating to the Notes and exercise their rights and remedies.

We have issued the Notes in the form of one or more global notes registered in the name of Cede & Co., as nominee of DTC. Beneficial interests in global notes will be shown on, and transfers of global notes will be effected only through, the records maintained by DTC. Except in limited circumstances, we will not issue certificated notes.

Accordingly, if a Note holder owns a beneficial interest in a global note, then it will not be considered an owner or holder of the Notes. Instead, DTC or its nominee will be the sole holder of the Notes. Unlike persons who have certificated notes registered in their names, owners of beneficial interests in global notes will not have the direct right to act on our solicitations for consents or requests for waivers or other actions from holders. Instead, those beneficial owners will be permitted to act only to the extent that they have received appropriate proxies to do so from DTC or, if applicable, a DTC participant. The applicable procedures for the granting of these proxies may not be sufficient to enable owners of beneficial interests in global notes to vote on any requested actions on a timely basis. In addition, notices and other communications relating to the Notes will be sent to DTC. We expect DTC to forward any such communications to DTC participants, which in turn would forward such communications to indirect DTC participants. However, we can make no assurances that Note holders will timely receive any such communications.

37

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

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

Risks related to our common stock

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

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

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

Certain provisions of our restated certificate of incorporation and restated bylaws and Delaware law could discourage, delay or prevent a change of control of our company or change in our management that the stockholders of our company consider favorable. These provisions:
authorize the issuance of “blank check” preferred stock that our board of directors could issue to increase the number of outstanding shares and to discourage a takeover attempt;
prohibit stockholder action by written consent, requiring all stockholder actions to be taken at a meeting of stockholders;
establish advance notice procedures for nominating candidates to our board of directors or proposing matters that can be acted upon by stockholders at stockholder meetings;
limit the ability of our stockholders to call special meetings of stockholders;
prohibit stockholders from cumulating their votes for the election of directors;
permit newly created directorships resulting from an increase in the authorized number of directors or vacancies on our board of directors to be filled only by majority vote of our remaining directors, even if less than a quorum is then in office;
provide that our board of directors is expressly authorized to make, alter or repeal our bylaws;
establish a classified board of directors so that not all members of our board are elected at one time;
provide that our directors may be removed only for “cause” and only with the approval of the holders of at least 66 2/3rds percent of our outstanding stock; and
require super-majority voting to amend certain provisions in our certificate of incorporation and bylaws.
Section 203 of the Delaware General Corporation Law may also discourage, delay or prevent a change of control of our company.
38

The exclusive forum provision in our amended and restated bylaws may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, or other employees, which may discourage lawsuits with respect to such claims.

Section 22 of the Securities Act creates concurrent jurisdiction for federal and state courts over all claims brought to enforce any duty or liability created by the Securities Act or the rules and regulations thereunder. In April 2020, we amended and restated our restated bylaws to provide that the federal district courts of the United States of America will, to the fullest extent permitted by law, be the exclusive forum for resolving any complaint asserting a cause of action arising under the Securities Act (a Federal Forum Provision). Our decision to adopt a Federal Forum Provision followed a decision by the Supreme Court of the State of Delaware holding that such provisions are facially valid under Delaware law. While there can be no assurance that federal courts or other state courts will follow the holding of the Delaware Supreme Court or determine that the Federal Forum Provision should be enforced in a particular case, application of the Federal Forum Provision generally means that suits brought by our stockholders to enforce any duty or liability created by the Securities Act must be brought in federal court and cannot be brought in state court. While neither the exclusive forum provision nor the Federal Forum Provision applies to suits brought to enforce any duty or liability created by the Exchange Act, Section 27 of the Exchange Act creates exclusive federal jurisdiction over all claims brought to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder. Accordingly, actions by our stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder also must be brought in federal court. Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder.

Any person or entity purchasing or otherwise acquiring or holding any interest in any of our securities shall be deemed to have notice of and consented to our exclusive forum provisions, including the Federal Forum Provision. These provisions may limit a stockholder’s ability to bring a claim in a judicial forum of their choosing for disputes with us or our directors, officers, or other employees, which may discourage lawsuits against us and our directors, officers, and other employees.

General risk factors

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

There has been significant volatility in the market price and trading volume of equity securities, which is often unrelated or disproportionate to the financial performance of the companies issuing the securities. These broad market fluctuations may negatively affect the market price of our common stock. The market price of our common stock could fluctuate significantly in response to the factors described in this “Risk Factors” section and elsewhere in this Form 10-K and other factors, many of which are beyond our control, including:
actual or anticipated variation in anticipated operating results of us or our competitors;
the financial projections we may provide to the public, any changes in these projections or our failure to meet these projections;
announcements by us or our competitors of new solutions, new or terminated significant contracts, commercial relationships or capital commitments;
changes in the regulatory environment affecting our healthcare customers, including impediments to their ability to obtain reimbursement for their services, and other actual or anticipated legal or regulatory developments in the United States or foreign countries;
actual or anticipated developments in our competitors’ businesses or the competitive landscape generally;
failure of securities analysts to maintain coverage of us, changes in financial estimates by any securities analysts who follow our company, or our failure to meet these estimates or the expectations of investors;
developments or disputes concerning our intellectual property or other proprietary rights;
commencement of, or our involvement in, litigation;
announced or completed acquisitions of businesses, technologies or assets by us or our competitor;
changes in operating performance and stock market valuations of other technology companies generally, or those in our industry in particular;
price and volume fluctuations attributable to inconsistent trading volume levels of our common stock;
our decision to seek additional equity or debt financing;
our public float relative to the total number of shares of our common stock that are issued and outstanding;
price and volume fluctuations in the overall stock market, including as a result of trends in the economy as a whole;
rumors and market speculation involving us or other companies in our industry;
the dissemination of adverse or misleading reports or opinions about our business;
any major change in our management;
39

unfavorable economic conditions and slow or negative growth of our markets; and
other events or factors, including those resulting from war, incidents of terrorism or health epidemics or contagious diseases.

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.disasters and epidemics or contagious diseases. A significant natural disaster, such as an earthquake, fire or a flood, or epidemic or contagious disease, 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, an epidemic or contagious disease, or by man-made problems, such as power disruptions, in the San Francisco Bay Area, Asia or Mexico could delay our research and development efforts, cause delays or cancellations of customer orders or delay deployment of our solutions, which could harm our business, operating results and financial condition.


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


The Sarbanes-Oxley Act requires, among other things, that we assess the effectiveness of our internal control over financial reporting annually and disclosure controls and procedures quarterly. In particular, we must obtain confidence in our internal control over financial reporting to allow management to report on the effectiveness of our internal control over financial reporting as required by Section 404 of the Sarbanes-Oxley Act. To the extent we find a material weakness or other deficiency in our internal control over financial reporting, the accuracy and timeliness of our financial reporting may be adversely affected.
Multiple negative consequences could ensue if a material weakness in our internal control over financial reporting is identified in the future, or we are not able to comply with the requirements of Section 404 in a timely manner, or we do not maintain effective controls. For example, our reported financial results could be materially misstated or could be restated, we could receive an adverse opinion regarding our controls from our independent registered public accounting firm, or we could be subject to investigations or sanctions by regulatory authorities. All of these outcomes would require additional financial and management resources, and the market price of our stock could decline.


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


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


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


We have in the past been, and may in the future become, subject to claims and litigation alleging violations of the securities laws or other related claims, which could harm our business and require us to incur significant costs. For example, a purported securities class action was filed in August 2013 in the United States District Court for the Northern District of California against us and certain of our officers and directors. The suit purported to allege claims for allegedly misleading statements regarding our business

and financial results. This suit was settled in 2016. The settlement, which called for payment of $9 million, was funded entirely and directly by our insurance carriers and paid during the three months ended September 30, 2016. Regardless of the outcome, these matters or future litigation may require significant attention from management and could result in significant
40

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:

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.Item 1B.Unresolved Staff Comments

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

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

Certain provisions of our restated certificate of incorporation and restated bylaws and Delaware law could discourage, delay or prevent a change of control of our company or change in our management that the stockholders of our company consider favorable. These provisions:
authorize the issuance of “blank check” preferred stock that our board of directors could issue to increase the number of outstanding shares and to discourage a takeover attempt;
prohibit stockholder action by written consent, requiring all stockholder actions to be taken at a meeting of stockholders;
establish advance notice procedures for nominating candidates to our board of directors or proposing matters that can be acted upon by stockholders at stockholder meetings;
limit the ability of our stockholders to call special meetings of stockholders;
prohibit stockholders from cumulating their votes for the election of directors;
permit newly created directorships resulting from an increase in the authorized number of directors or vacancies on our board of directors to be filled only by majority vote of our remaining directors, even if less than a quorum is then in office;
provide that our board of directors is expressly authorized to make, alter or repeal our bylaws;
establish a classified board of directors so that not all members of our board are elected at one time;
provide that our directors may be removed only for “cause” and only with the approval of the holders of at least 66 2/3rds percent of our outstanding stock; and
require super-majority voting to amend certain provisions in our certificate of incorporation and bylaws.
Section 203 of the Delaware General Corporation Law may also discourage, delay or prevent a change of control of our company.

COVID-19 Pandemic
The ongoing outbreak of coronavirus, SARS-CoV-2, or COVID-19, continues to be a global pandemic and public health emergency. Many federal, state and local governments and private entities have mandated various restrictions, including travel restrictions, restrictions on public gatherings, stay at home orders and advisories and quarantining of people who may have been exposed to the virus. Since our last filing, COVID-19 infections have continued and are increasing in many geographies of the world as new variants arise and these rates may continue to increase. Over the course of the COVID-19 pandemic, our business has been impacted in several ways, including the following:
We have taken measures to protect the health and safety of our employees, primarily by shifting the majority of our employees to remote work.
Our access to our healthcare customers’ locations for sales and implementation activities was limited in many cases. The sales cycle and implementation timeline for broader strategic deals in some cases has been elongated as they shifted their primary focus to preparing for and responding to the pandemic.
We have experienced some delays in receiving parts due to supplier and shipping issues.
Overall, the outbreak did not have a material impact on our operating results or business in the year ended December 31, 2021. While future impacts cannot be predicted at this time, the shift in hospital resources, attention to treatment of COVID-19 patients and declines in hospital revenues may result in reduced demand for our products and solutions, longer sales cycles, and/or delays of customer implementations, which could negatively impact our financial condition.

We have generated operating cash flows in the past and our $332.4 million in cash. In addition, $2.5 million has been set aside for retention bonuses for key employeescash and short-term investments provides us with ample liquidity to meet our current needs. However, given the dynamic nature of which $0.5 million and $1.0 million was paid in December 2016 and October 2017, respectively and $1.0 million will be paid in October 2018.this situation, we cannot accurately estimate the impacts of COVID-19 on our financial condition, results of operations or cash flows.

Revenue.    We generate revenue from contracts with customers should be recognized. Under the new guidance, an entity should recognizesale of products and services. As discussed further in the section titled “Critical accounting policies and estimates—Revenue recognition”, revenue to depictis recognized utilizing a five-step approach which depicts the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.
The new guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application(modified retrospective method). 
We adopted the new guidance on January 1, 2018 using the full retrospective method, which requires us to present our historical financial information for fiscal years 2016 and 2017 as if the new revenue guidance had been applied to all prior periods. 
The most significant impact of the standard relates to the timing of revenue recognition for software licenses sold with professional services where we did not have vendor specific objective evidence (“VSOE”) for professional services under current guidance.   Under the new standard, the requirement to have VSOE for undelivered elements is eliminated and we will recognize revenue for software licenses upon transfer of control to our customers. Additionally, the new standard requires the capitalization and amortization of costs related to obtaining a contract, such as sales commissions, which are currently recorded as an expense to sales and marketing at the time they are incurred.  

The adoption of the standard will result in the recognition of additional revenue of $2.7 million and $4.3 million for the years ended December 31, 2017 and 2016, respectively, an increase in gross profit of $2.7 million and $4.3 million for the years ended December 31, 2017 and 2016, respectively, an increase (decrease) in sales and marketing expense of $0.1 million and $(1.5) million for the years ended December 31, 2017 and 2016, respectively, and a decrease in loss from operations of $2.6 million and $5.8 million for the years ended December 31, 2017 and 2016, respectively. In addition, the adoption of the standard will result in a decrease in total net deferred revenue of $7.8 million and $5.2 million as of December 31, 2017 and 2016, respectively, driven by the upfront recognition of software licenses sold with professional services for which we do not have VSOE, and an increase in total deferred commissions of $10.3 million and $10.4 million as of December 31, 2017 and 2016, respectively, which will be recognized in sales and marketing expense in future periods. The adoption of the standard will not have a significant impact to the provision for income taxes and will not have an impact on net cash from or used in operating, investing, or financing activities on our consolidated statements of cash flows. Refer to Note 1 in the notes to consolidated financial statements for the impact of adoption of the standard on the Company's consolidated balance sheets and consolidated statements of operations.

Components of operating results
Revenue.    We generate revenue from the sale of products and services. As discussed further in the section titled “Critical accounting policies and estimates—Revenue recognition” below, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the price is fixed or determinable and collection is reasonably assured.
Revenue is comprised of the following:
 
Product.     Our solutions include both hardware and software. We refer to hardware revenue as device revenue, which includes revenue from sales of our communication badges and badge accessories, which include batteries, battery chargers, lanyards, clips and other ancillary badge components as well as revenue from the resale of MC40third-party devices and related accessories. Software revenue is derived primarily from the sale of perpetual or term-based licenses to our Vocera Communication and Workflow System. We derive additional software revenue from the sale of termTerm based licenses and hosted software subscriptions, whichdelivered on-premises can be renewed on a subscription basis. Product revenue is generally recognized upon shipment of hardware and perpetual licenses and, in the casedelivering of term licenses or subscription services, ratably over the applicable term.
licenses.
Service. We receive service revenue from sales of software maintenance, sales of cloud-based software subscriptions, extended hardware warranties and professional services. SoftwareSubscription revenue is generally recognized ratably over the application term. Cloud-based software subscription and software maintenance isare 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-offsprovisions 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
46

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.
Interest expense.      Interest expense consists of amortization of debt discount and debt issuance costs as well as the contractual interest incurred due to the issuance of the Convertible Senior Notes which are discussed in further detail in Note 8 of the Notes to Consolidated Financial Statements.
Other income (expense), net.    Other income (expense), net consists primarily of foreign exchange gains and losses.
Provision for income taxes.    We are subject to income taxes in the countries where we sell our solutions. We anticipate that in the future as we expand our sale of solutions to customers outside the United States, we will become subject to taxation based on the foreign statutory rates in the countries where these sales took place and our effective tax rate could fluctuate accordingly. Currently, each of our international subsidiaries is operating under cost plus agreements where the U.S. parent company reimburses the international subsidiary for its costs plus an arm's length profit.
Income taxes are computed using the asset and liability method, under which deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances have been established to reduce deferred tax assets to the amount reasonably expected to be realized. Changes in valuation allowances are reflected as a component of provision for income taxes.
At December 31, 2017,2021, we held a $45.3$61.5 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.

Interest income. Interest income decreased $0.1$2.1 million for the year ended December 31, 20172021, compared to the year ended December 31, 20162020. This decrease was due to earning a lower rate of return on our investments.
Interest expense. Interest expense decreased $6.2 million for the year ended December 31, 2021, compared to the year ended December 31, 2020.

The negative effective tax rate for 20172021 was due primarily to the re-measurement of the net deferred tax liabilities, resulting in a deferred tax benefit of $0.7 million upon the enactment of the Tax Cuts and Jobs Act as well as the impact of pre-tax losses in the U.S. operations, partially offset by income taxes on our foreign operations. The negative effective tax rate of 3.2% in 2016 is due primarily to the impact of pre-tax losses in the U.S. operations offset by income taxes from foreign operations.

Device revenue increased $9.5 million, or 23.5%, and software revenue increased $5.4 million, or 35.9%, for the year ended December 31, 2016, compared to the year ended December 31, 2015. The increase in device revenue, which related entirely to our Communication and Workflow System, 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 software platform.

Service revenue increased $8.7 million, or 17.9%, for the year ended December 31, 2016 compared to the year ended December 31, 2015. Software maintenance and support revenue increased $5.0 million, or 13.0%, and professional services and training revenue increased $3.7 million, or 36.9%, for the year ended December 31, 2016 compared to the year ended December 31, 2015. 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 solutions.

Cost of product revenue increased $3.1 million, or 15.9%, for the year ended December 31, 2016 compared to the year ended December 31, 2015. The cost of product revenue increased primarily due to a higher number of communication badges and related accessories sold and amortization of intangibles related to the acquisition in October 2016. Product gross margin as a percentage of product revenue increased in the year ended December 31, 2016 compared to the year ended December 31, 2015 due to decreased costs related to our hardware products, a larger mix of software revenue and higher absorption of fixed overhead costs.

Research and development expense. Research and development expense increased $1.3 million, or 7.5%, for the year ended December 31, 2016 compared to the year ended December 31, 2015. This increase was primarily due to a $1.2 million increase in compensation and benefits associated with increased headcount.

Sales and marketing expense. Sales and marketing expense increased $5.2 million, or 10.8%, for the year ended December 31, 2016 compared to the year ended December 31, 2015. This was primarily due to a $4.1 million increase in compensation and benefits associated with increased headcount and performance. The sales and marketing expense increase was also due to a $0.4 million increase in marketing development costs, a $0.2 million increase in travel and $0.2 million in amortization of intangibles related to the acquisition in October 2016.

General and administrative expense. General and administrative expense increased $7.8 million, or 46.4%, from the year ended December 31, 2016 compared to the year ended December 31, 2015. This resulted primarily from an increase of $5.1 million in acquisition related expenses from the acquisition in October 2016, a $2.0 million increase in compensation and benefits due to increased headcount and performance and a $0.7 million increase in outside services. Included in the $5.1 million of acquisition related expenses is $2.6 million of non-cash salary expense related to a portion of the purchase price that is expected to be distributed to certain employees who were not selling shareholders of the acquired business ("Employee Payments"). For further discussiontax benefit on the Employee Payments, please refer to Note 11 in the notes to consolidated financial statements.

As of December 31, 2017,2021, we had cash and cash equivalents and short-term investments of $81.2$332.4 million.

In March 2021, we issued $200.0 million in aggregate principal amount of 0.50% Convertible Senior Notes and no debt.we used part of the net proceeds from the issuance of the 2026 Notes to retire approximately $102.9 million aggregate principal amount of the 2023 Notes. In addition, in April 2021, the purchasers partially exercised the overallotment option and we issued an additional $24.5 million aggregate principal amount of the 2026 Notes. For additional information, see Note 8 of the Notes to the consolidated financial statements.
During 2017, 20162021 and 2015,2020, our purchases of property and equipment were $2.8 million, $4.7$3.8 million and $1.2$4.2 million, respectively. The expenditures in 20172021 primarily relaterelated to purchases associated with the new company headquarters and other leasehold improvements, manufacturing tools and equipment, and computer equipment. The expenditures in 2016 primarily relate to leasehold improvements related to the renovation of our corporate offices. The expenditures in 20152020 primarily related to leasehold improvements, manufacturing tools and equipment, and computer equipment.
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.

As of December 31, 2017, we had $1.3 million of net deferred tax liabilities and $0.3 million from uncertain tax positions, both recorded within other long-term liabilities. The timing and amounts of any payments that could result from the net deferred tax liabilities and unrecognized tax benefits will depend upon a number of factors. Accordingly, the timing and amounts of any eventual payment cannot be estimated for inclusion in the table above. We do not expect a significant tax payment related to these obligations to occur within the next 12 months. Such tax contingencies are separately disclosed and discussed in Note 10 of the notes to our consolidated financial statements.

Off-balance sheet arrangements
During 2017, 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, contingent consideration, and the provision for income taxes. We base our estimates and judgments on our historical experience, knowledge of factors affecting our business and our belief as to what could occur in the future considering available information and assumptions that we believe to be reasonable under the circumstances.
The accounting estimates we use in the preparation of our consolidated financial statements will change as events occur, more experience is acquired, additional information is obtained and our operating environment changes. Changes in estimates are made when circumstances warrant. Such changes in estimates and refinements in estimation methodologies are reflected in our reported results of operations and, if material, the effects of changes in estimates are disclosed in the notes to our consolidated financial statements. By their nature, these estimates and judgments are subject to an inherent degree of uncertainty and actual results could differ materially from the amounts reported based on these estimates.
While our significant accounting policies are more fully described in Note 1 of the “Notes to our consolidated financial statements” included in Item 8, “Financial Statements and Supplementary Data,” we believe the following reflects our critical accounting policies and our more significant judgments and estimates used in the preparation of our financial statements.
Revenue recognitionRecognition
We derive revenue from the salesSome of communication badges, smartphones, perpetual software licenses for software that is essential to the functionality of the 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 badges, which may include clinical integration and mobile application software 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 involvesour contracts with customers contain multiple elements, such as sales of badges or smartphones, 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, but may take longer depending on the complexity of the work involved.
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 software maintenance. When VSOE of selling price is not available, third-party evidence (TPE) of selling price for similarobligations. Determining whether 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.
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. 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 software maintenance, which we refer to as maintenance and support. Our revenue arrangements do not include a general right of return relative to the delivered products. We apply the combined services approach for arrangements in which we have VSOE for software maintenance but not for professional services. Under this approach, we ratably recognize revenue over the longer of the period over which professional services is expected to be delivered or the software maintenance period.

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,distinct performance obligations that should be accounted for separately versus together may require significant judgment. For these contracts, we recognize revenueaccount for such products in an amount equal to the net present value of the minimum lease payments. Unearned incomeindividual performance obligations separately if they are distinct. The transaction price 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.

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 andseparate performance obligations on a relative standalone selling price (“SSP”) basis. If the carrying value ofcontract contains a single performance obligation, the net investment in leaseentire transaction price is included in product revenue. Proceeds allocated to the executory cost componentsingle performance obligation. For performance obligations that we routinely sell separately, such as support and maintenance on our core offerings, we determine SSP by evaluating the standalone sales over the trailing 12 months. For those that are accounted for initially as financing liabilities, with subsequent amortization recorded in revenue for maintenance, extended warrantynot sold routinely, we determine SSP based on our overall pricing trends and battery refresh programs, offset by interest expense.objectives, taking into consideration market conditions and other factors, including the value of our contracts, the products sold and geographic locations.
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 repairreplacement costs, and knowledge of specific product failures, (if any).if any. The specific product warranty includes parts and labor over a period generally ranging from one to three years. We generally do not provide no warrantyperformance warranties 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 20172021 was $0.1$0.2 million, compared to $0.3 million in 2020 and $0.2 million in 2016 and $0.9 million in 2015.2019. 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
Performance Stock optionsUnits
We record all stock-based awards, whichPerformance stock units consist of grants of performance-based restricted stock option grants, atunits to certain members of executive management that vest contingent upon the achievement of pre-determined market and service conditions (referred to herein as “performance stock units”). The 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. Noperformance stock options were issued during the year ended December 31, 2017 and 2016.
We use the Black-Scholes option-pricingunits is estimated using a Monte-Carlo simulation model to calculatewhich is a probabilistic approach for calculating the fair value of the awards. The Monte-Carlo simulation is a statistical technique used, in this instance, to simulate future stock options on their grant date. Thisprices of Vocera relative to constituents in the S&P 600 Health Care Equipment and Services Index. Key assumptions for the Monte-Carlo simulation 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,are the risk-free interest rate, and expected dividend yield. The following assumptions were used for each respective period for employee stock-based compensation:
Year ended December 31,
2015
Expected term (in years)5.39
Volatility41.3% - 41.8%
Risk-free interest rate1.62% - 1.63%
Dividend yield0.0%

We base the risk-free rate for thevolatility, 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. For the year ended December 31, 2017 the straight-line amortization is reduced by actual forfeitures. For the years ended December 31, 2016 and 2015 the straight-line amortization 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
In addition to stock options, we also issue restricted stock units to our employees, 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. 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.correlation coefficient.
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 annual assessment date is October 1st and the results of our assessment performed as of October 1st indicated nothat an impairment had been incurred.was not required. No impairment was recorded in 2017, 20162021, 2020 or 2015.2019. As of December 31, 2017,2021, no changes in circumstances indicate that goodwill carrying values may not be recoverable. Application of the goodwill impairment test requires judgment. Circumstances that could affect the valuation of goodwill include, among other things, a significant change in our business climate and the buying habits of our customers along with changes in the costs to provide our products and services.
Intangible assets
Intangible assets are amortized over their estimated useful lives. Upon completion of development, acquired in-process research and development assets are generally considered amortizable, finite-lived assets and are amortized over their estimated useful lives.
Finite-lived intangible assets consist of customer relationships, developed technology, trademarks, backlog and non-compete agreements. We evaluate our intangible assets for impairment at the asset group level, which means the intangibles grouped with other assets and liabilities at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. Management has concluded that our asset groups align with our reporting units.unit. The intangible assets are allocated to the Product and Services asset groups, given that the Product and Services asset groups are the lowest level for which discrete cash flow information are identifiable, independent from other assets. We assess the recoverability of these assets whenever adverse events or changes in circumstances or business climate indicate that expected undiscounted future cash flows related to such intangible assets may not be sufficient to support the net book value of such assets. An impairment is recognized in the period of identification to the extent the carrying amount of an asset exceeds the fair value of such asset. No impairment of intangible assets was recorded in 2017, 20162021, 2020 or 2015.2019.
Significant judgments required in assessing the impairment of goodwill and intangible assets include the identification of the reporting units,unit, 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.
53

Income taxes
We use the asset and liability method of accounting for income taxes. Under this method, we record deferred income taxes based on temporary differences between the financial reporting and tax bases of assets and liabilities and use enacted tax rates and laws that we expect will be in effect when we recover those assets or settle those liabilities, as the case may be, to measure those taxes. In cases where the expiration date of tax carryforwards or the projected operating results indicate that realization is not likely, we provide for a valuation allowance. Valuation allowances are established when necessary to reduce deferred tax assets to the amounts expected to be realized.
We have deferred tax assets, resulting from deductible temporary differences that may reduce taxable income in future periods. A valuation allowance is required when it is more likely than not that all or a portion of a deferred tax asset will not be realized. In assessing the need for a valuation allowance, we estimate future taxable income, considering the feasibility of ongoing tax-planning strategies and the realizability of tax loss carryforwards. Valuation allowances related to deferred tax assets can be impacted by changes in tax laws, changes in statutory tax rates and future taxable income levels. If we were to determine that we would be able to realize our deferred tax assets in the future in excess of the net carrying amounts, we would decrease the recorded valuation allowance through an increase to income in the period in which that determination is made. Due to the amount of netrecurring operating losses, available for income tax purposeswe established a full valuation allowance through December 31, 2017,2021, 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, 2017,2021, we had a valuation allowance against net deferred tax assets of $45.3$61.5 million. We 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 20102014 are subject to tax authority examinations. Additionally, our net operating losses and research credits after 2010 are subject to tax authority adjustment.


Recently issued accounting guidance


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


Item 7A.Quantitative and Qualitative Disclosures about Market Risk
Item 7A.Quantitative and Qualitative Disclosures about Market Risk
The primary objective of our investment activities is to preserve principal while maximizing yields without significantly increasing risk. To achieve this objective, historically we have invested in money market funds. With the proceeds from our two public offerings in 2012 and our Notes offerings in 2018 and 2021, 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, a majority of our operations, have consisted ofincluding research and development, and sales, activitieshave been 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 developingconsidering 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 shareholdersStockholders and the Board of Directors of Vocera Communications, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Vocera Communications, Inc. and subsidiaries (the "Company") as of December 31, 20172021 and 2016,2020, the related consolidated statements of operations, comprehensive loss, stockholder’sstockholders' equity, and cash flows for each of the three years in the period ended December 31, 20172021, and the related notes (collectively referred to as the “financial statements”"financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 20172021 and 2016,2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017,2021, in conformity with the accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2017,2021, based on criteria established in Internal Control - Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 5, 2018,February 22, 2022, expressed an unqualified opinion on the Company’sCompany's internal control over financial reporting.

Change in Accounting Principle
As discussed in Note 8 to the financial statements, the Company has changed its method of accounting for convertible debt effective January 1, 2021 using a modified retrospective transition approach due to adoption of Accounting Standards Codification No. 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity.
Basis for Opinion

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

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

Critical Audit Matters
The critical audit matters communicated below are matters arising from the current-period audit of the financial statements that were communicated or required to be communicated to the audit committee and that (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.
Revenue Recognition - Refer to Note 2 to the Financial Statements
Critical Audit Matter Description
The Company recognizes revenue upon transfer of control of promised products or services to customers in an amount that reflects the consideration the Company expects to receive in exchange for those products or services. The Company offers products and services including its proprietary communication badges, perpetual software licenses, professional services, maintenance and support services, and extended hardware warranties. Product revenue was $118 million and service revenue was $116 million for the year ended December 31, 2021.

56

Significant judgment is exercised by the Company in determining revenue recognition for the Company’s customer contracts, and includes the following:
Identification and evaluation of terms and conditions within contracts that impact revenue recognition
Determination of whether promised goods or services, such as hardware and software licenses, are capable of being distinct and are distinct in the context of the Company’s customer contracts which leads to whether they should be accounted for as individual or combined performance obligations
Determination of stand-alone selling prices for each distinct performance obligation and for products and services that are not sold separately
Determination of transaction price and allocation of transaction price to identified performance obligations
We identified revenue recognition as a critical audit matter because of these significant judgments required by management. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate whether revenue was recognized to depict the transfer of promised products or services to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.
How the Critical Audit Matter Was Addressed in the Audit
Our principal audit procedures related to the Company’s revenue recognition for these customer agreements included the following:
We tested the effectiveness of controls related to the identification and evaluation of terms and conditions in contracts, determination of distinct performance obligations, determination of the standalone selling prices, determination of transaction price, allocation of the transaction price to the performance obligations in the contract, and recognition of revenue when, or as, the Company satisfies a performance obligation.
We evaluated management’s significant accounting policies related to revenue recognition for reasonableness.
We selected a sample of recorded revenue transactions and performed the following procedures:
Obtained and read customer purchase orders and the underlying contract for each selection, including master agreements and related amendments to evaluate if relevant contractual terms have been appropriately considered by management.
Evaluated management’s application of their accounting policy and tested revenue recognition for specific performance obligations by comparing management’s conclusions to the underlying master agreement and any related amendments.
Tested the mathematical accuracy of management’s calculations of revenue and the associated timing of revenue recognized in the financial statements.
We evaluated the reasonableness of management’s estimate of standalone selling prices for products and services that are not sold separately by performing the following:
Assessed the appropriateness of the Company’s methodology and mathematical accuracy of the determined standalone selling prices.
Tested the completeness and accuracy of the source data utilized in management’s calculations.
Business Acquisitions — Refer to Note 12 to the Financial Statements
Critical Audit Matter Description
As described in Note 12, the Company completed the acquisition of Patient Safe Solution, LLC (“PSS”) for capital consideration of $36 million on May 4, 2021. The Company accounted for the acquisition of PSS under the acquisition method of accounting for business combinations. Accordingly, the purchase price was allocated on a preliminary basis, to the assets acquired and liabilities assumed based on their respective fair values, including developed technology intangible assets with an aggregate fair value of approximately $5.3 million. The Company estimated the fair value of the developed technology intangible assets using an income-based valuation methodology, which is a specific relief-from-royalty method.

Significant judgment is exercised by the Company in determining the fair value of the acquired developed technology intangible assets, including the following:
Future expected revenue for acquired developed technology,
57

Useful life of acquired developed technology,
Valuation methodology, and
Discount and royalty rates.
Given the fair value determination of developed technology intangible assets acquired requires management to make significant estimates related to the above assumptions, performing audit procedures to evaluate the reasonableness of these assumptions required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists. Thus, we deemed this to be a critical audit matter.
How the Critical Audit Matter Was Addressed in the Audit
Our audit procedures related to the fair value of developed technology intangible assets acquired for PSS included the following, among others:
We tested the effectiveness of controls over the purchase price allocation, including management’s controls over the forecast utilized, and the valuation methodology and inputs for estimating the fair value of developed technology intangible assets acquired.
Our internal valuation specialists assisted us in evaluating the reasonableness of the (1) valuation techniques used for developed technology intangible assets acquired, (2) valuation assumptions used in the relief-from-royalty method including royalty rate, obsolescence factor, and discount rates, and (3) testing the mathematical accuracy of the calculation of estimated fair value of the developed technology intangible acquired assets, and developing a range of independent estimates and comparing our estimates to those used by management.
We assessed the reasonableness of management’s projections of economic useful life of developed technology intangible assets acquired, and percentage of revenue attributable to the intangible asset by comparing the assumptions used in the projections to external market sources, existing contracts, historical data, and results from other areas of the audit.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

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

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Vocera Communications, Inc. and subsidiaries (the “Company”) as of December 31, 2017,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2017,2021, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB),the consolidated financial statements as of and for the year ended December 31, 2017,2021, of the Company and our report dated March 5, 2018,February 22, 2022 expressed an unqualified opinion on those financial statements.

Basis for Opinion

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

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

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

The Company's system responds to over 100 spoken commands.Smartbadge both inside and outside the hospital, replacing legacy pagers and in-building wireless phones.
The Company was incorporated in Delaware on February 16, 2000. The Company formed wholly-owned subsidiaries Vocera Communications UK LtdLtd. and Vocera Communications Australia Pty Ltd. in 2005, Vocera Canada, Ltd. in 2010, Vocera Communications India Private Ltd. in 2013, Vocera Communications Middle East FZ LLC in 2014, and acquired Extension, LLC in 2016.2016, EASE Applications, LLC ("EASE") in 2020 and PatientSafe Solutions, Inc. (“PatientSafe”) in 2021.
Since its inception, the Company has incurred significant losses and, as of December 31, 2017,2021, had an accumulated deficit of $141.7$153.3 million. The Company has funded its operations primarily with customer payments for its products and services, proceeds from the issuance of common stock in connection with its initial public offering ("IPO")(IPO) and follow-on offering.offering and proceeds from the issuance of convertible senior notes. As of December 31, 2017,2021, the Company had cash, cash equivalents and short-term investments of $81.2$332.4 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.
Merger Agreement
On January 6, 2022, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”), with Stryker Corporation, a Michigan corporation (“Parent”) and Voice Merger Sub Corp., a Delaware corporation and a direct or indirect wholly owned subsidiary of Parent (“Merger Sub”).
The Merger Agreement provides that, subject to the terms and conditions of the Merger Agreement, Merger Sub would commence a cash tender offer (the “Offer”) to purchase all of the outstanding shares of our common stock at a price per share equal to $79.25, net to the seller in cash, without interest, and subject to withholding taxes required by applicable law (the “Offer Price”). Following the expiration of theOffer and the acceptance by Merger Sub of the tendered shares in the Offer, on the terms and subject to the conditions in the Merger Agreement, Merger Sub would merge with and into Vocera, with Vocera continuing as the surviving corporation and becoming a wholly owned subsidiary of Stryker (the “Merger” and collectively with the Offer, the “Transaction”), and each then-outstanding share of our common stock (with certain limited exceptions) would be converted into the right to receive the Offer Price. Consummation of the Transaction is subject to various conditions, including, in respect of Merger Sub’s obligation to purchase and accept the tendered shares in the Offer, the condition that the number of shares validly tendered and not properly withdrawn prior to the Expiration Time (as defined in the Merger Agreement) is, when added to the shares, if any, owned by Parent, Merger Sub, or any subsidiary of Parent, represents at least a majority of all shares of our common stock then outstanding. However, there is no assurance that all of the various conditions to the Transactions will be satisfied, or that the Transaction will be completed on the proposed terms pursuant to the Merger Agreement within the expected timeframe, or at all. Furthermore, there are additional inherent risks to the Transaction, including the risks detailed elsewhere in this Annual Report on Form 10-K. The Transaction is expected to close in the first quarter of 2022, subject to the satisfaction of customary closing conditions.
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)("GAAP").
66

Use of estimates and reclassifications
The preparation of financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expense during the reporting periods. The estimates include, but are not limited to, revenue recognition, warranty reserves, allowance for doubtful accounts, inventory reserves, bonuses, goodwill and intangible assets, stock-based compensation expense, provisions for income taxes, contingent consideration 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.
Certain reclassifications have been made to the prior year financial statements to conform to the current year presentation. These reclassifications had no impact on the previously reported net loss or accumulated deficit.
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 Company's marketable securities are recorded at their estimated fair value. Unrealized gains or losses on available-for-sale securities are reported in other comprehensive loss. The Company periodically assesses whether its securities are in an unrealized loss position which may become a realized loss in order to determine if an allowance for doubtful accounts reflects the Company’s best estimate of probablecredit losses inherent in the Company’sis required.
Accounts receivable and allowance for credit losses
Accounts receivable primarily include amounts related to receivables portfolio determined on the basis of historical experience, specific allowances for known troubled accounts and other currently available evidence.from customers. The Company has not experienced significant credit losses from itsmonitors collectability of accounts receivable.receivable primarily through review of the accounts receivable aging. 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 When collection is at risk, the changesCompany assesses the impact on amounts recorded for credit losses and, if necessary, records a charge in the period such a determination is made, reflecting the Company’s best estimate of probable losses inherent in the Company’s receivables portfolio. The Company has not experienced significant credit losses from its accounts receivable. No allowance for doubtful accounts:credit losses was recorded in the years ended December 31, 2021, 2020 and 2019.

Inventories
Inventories are valuedrecorded at the lower of standard cost (which approximates actual cost on a first-in, first-out basis) or market (netnet realizable value or replacement cost).value. 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 componentcomponents of the Company’s products isare currently manufactured by a third-party contractorcontractors in Mexico.Mexico and Taiwan. A significant disruption in the operations of this contractorthese contractors may impact the production of the Company’s products for a substantial period of time, which could harm the Company’s business, financial condition and results of operations.
Concentration of credit risk with respect to trade accounts receivable is considered to be limited due to the diversity of the Company’s customer base and geographic sales areas. At December 31, 20172021 and 2016, no customer accounted for 10% or more of accounts receivable. At December 31, 20172020, one reseller represented 26.3%17.4% and 32.7%, respectively of our accounts receivable. For the years ended December 31, 2017, 20162021, 2020 and 2015,2019, no customer represented 10% or more of revenue.
67

Other risks and uncertainties
The ongoing outbreak of coronavirus, SARS-CoV-2, or COVID-19, continues to be a global pandemic and public health emergency. Many federal, state and local governments and private entities have mandated various restrictions, including travel restrictions, restrictions on public gatherings, stay at home orders and advisories and quarantining of people who may have been exposed to the virus. Since the Company's last filing, COVID-19 infections have continued in many geographies of the world. In response to the ongoing and evolving COVID-19 pandemic, the Company considered the impact of the estimated economic implications on critical and significant accounting estimates, including assessment of collectability of customer contracts and the valuation of accounts receivable. Overall, the COVID-19 pandemic has not had a material impact on the Company's operating results or business in the year ended December 31, 2021. While future impacts cannot be predicted at this time, the shift in hospital resources, attention to treatment of COVID-19 patients and declines in hospital revenues may result in reduced demand for the Company's products and solutions, longer sales cycles and/or delays of customer implementations, which could negatively impact financial condition.
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 of three years, except for major ERP implementations, for which the Company assumes a five year useful economic life.life of five years. 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 discountedundiscounted 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 material impairment charges.
SoftwareInternal-use software development costs 
For internal-use software, theThe Company capitalizes certain internal and external costs incurred in itsthe acquisition and creation.creation of internal-use software. 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.years. 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, 2017, 20162021, 2020 and 2015,2019, the Company capitalized costs of $0.3$0.2 million, zero$0.5 million and zero,$0.6 million, respectively.

Segment
The Company’s chief operating decision maker ("CODM") receives and regularly reviews financial information on an entity-wide basis. The CODM considers entity-wide financial information in deciding how to allocate resources in assessing performance of the Company’s communication and clinical workflow solutions and services business. There are no segment managers who are held accountable for operations, operating results or plans for levels or components. The Company’s CODM is its Chief Executive Officer. As a result, the Company reports its financial performance consistent with its single reporting segment and operating unit structure.
Goodwill and intangible assets
The Company allocates the purchase price of any acquisitions to tangible assets and liabilities and identifiable intangible assets acquired. Any residual purchase price is recorded as goodwill.
Goodwill
Goodwill is tested for impairment at the reporting unit level at least annually, or more often if events or changes in circumstances indicate the carrying value may not be recoverable. The Company has identified two1 operating segments (Product and Service)segment which management also considers to be a reporting units.unit. In testing for goodwill impairment, the Company may elect to utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of athe reporting unit is less than its carrying value. If such qualitative assessment indicates that goodwill impairment is more likely than not, the Company performs a two-stepquantitative impairment test. The Company performed its goodwill impairment assessment on October 1, 20172021 using a qualitative assessment and determined that no impairment existed as of the date of the impairment test because the fair value of eachthe Company's reporting unit more likely than not exceeded its carrying value. As of December 31, 2017,2021, no changes in circumstances indicate that goodwill carrying values may not be recoverable.
68

Intangible assets
Intangible assets are amortized over their estimated useful lives. Upon completion of development, acquired in-process research and development assets are generally considered amortizable, finite-lived assets and are amortized over their estimated useful lives. Finite-lived intangible assets consist of customer relationships, developed technology, trademarks, backlog and non-compete agreements. The Company evaluates intangible assets for impairment by assessing the recoverability of these assets whenever adverse events or changes in circumstances or business climate indicate that expected undiscounted future cash flows related to such intangible assets may not be sufficient to support the net book value of such assets. An impairment is recognized in the period of identification to the extent the carrying amount of an asset exceeds the fair value of such asset. No impairment of intangible assets was recorded in the years ended December 31, 2017, 20162021, 2020 or 2015.2019.
Leases
The Company determines if an arrangement is a lease at inception. Operating leases are included in other long-term assets, accrued payroll and other current liabilities and other long-term liabilities on the consolidated balance sheets.
The Company has elected an accounting policy to not recognize short-term leases (one year or less) on the consolidated balance sheet. The Company also elected the package of practical expedients which applies to leases that commenced before the adoption date. By electing the package of practical expedients, the Company did not need to reassess whether any existing contracts are or contained a lease or the lease classification for any existing leases.
Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate, the incremental borrowing rate is used based on the information available at commencement date in determining the present value of future payments. The Company’s incremental borrowing rate is determined by estimating the cost to the Company to borrow a collateralized amount equal to the total lease payments over a similar lease term and is based on credit-adjusted and term-specific discount rates, using a third-party yield curve. The operating lease right-of-use asset also includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company accounts for lease components and non-lease components as a single lease component.
Business combination
Acquisitions are accounted for using the acquisition method. Goodwill is measured at the acquisition date as the excess of the purchase price over the fair value of the assets acquired and liabilities assumed. Significant estimates and assumptions are made by management to value such assets and liabilities. Although the Company believes that those estimates and assumptions are reasonable and appropriate, they are inherently uncertain and subject to refinement. Additional information related to the acquisition date fair value of acquired assets and assumed liabilities obtained during the measurement period, not to exceed one year, may result in changes to the recorded values of such assets and liabilities, resulting in an offsetting adjustment to the goodwill associated with the business acquired. Uncertain tax positions and tax-related valuation allowances are initially established in connection with a business combination as of the acquisition date. The Company continues to collect information and reevaluate these estimates and assumptions. Any contingent consideration payable is recognized at fair value at the acquisition date. Liability-classified contingent consideration is remeasured each reporting period, with changes in fair value recognized in earnings until the contingent consideration is settled. Acquisition related costs incurred in connection with a business combination are expensed as incurred.
Revenue recognition
The core principle of Accounting Standards Codification ("ASC") 606, Revenue from Contracts with Customers (Topic 606) is to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This principle is achieved through applying the following five-step approach:
Identification of the contract, or contracts, with a customer - A contract with a customer exists when (i) the Company enters into an enforceable contract with a customer that defines each party’s rights regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, (ii) the contract has commercial substance and, (iii) the Company determines that collection of substantially all consideration for goods or services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. The Company derives revenue fromapplies judgment in determining the salescustomer’s ability and intention to pay, which is based on a variety of badges, smartphones, perpetual software licenses for software that is essentialfactors including the customer’s historical payment experience or, in the case of a new customer, published credit and financial information pertaining to the functionalitycustomer. Customer payments received by the Company are non-refundable.
Identification 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 badges, which may include Clinical Integration and Vocera smartphone applications 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,performance obligations in the form ofcontract - Performance obligations promised in a written contract amendments to that contract, or purchase orders from a third party;
delivery has occurredare identified based on the goods 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 valuethat will be transferred to the customer that are capable of being both: a)
69

functionally distinct, whereby the customer can benefit from the goods or service either on their own or together with other resources that are readily available from third parties or from the Company, and b) contractually distinct, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. To the extent a contract includes multiple promised goods or services, the Company applies judgment to determine whether promised goods or services are capable of being distinct and unique in the context of the contract. If these criteria are not met the promised goods or services are accounted for as a combined performance obligation.
Determination of the transaction price - The transaction price is determined based on the consideration to which the Company is entitled in exchange for transferring goods or services to the customer.
Allocation of the transaction price to the performance obligations in the contract - If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (SSP) basis. The Company allocates arrangement consideration at the inception of the arrangement to all deliverables using the relativedetermines standalone selling price method. This method requiresbased on the Company to determine the selling price at which each deliverable could be sold if it were sold regularly on a standalone basis. When available, the Company uses vendor-specific objective evidence ("VSOE") of the selling price. VSOE represents the price charged for a deliverable when itperformance obligation is sold separately, or for a deliverable not yet being sold separately,separately. If the price established by management with the relevant authority. The Company has established VSOE of the selling price for software maintenance. When VSOE ofstandalone selling price is not available, third-party evidence ("TPE") ofobservable through past transactions, the Company estimates the standalone selling price for similar products and services is acceptable; however, the Company's offerings and market strategy differ from those of its competitors, such that the Company cannot obtain sufficient comparabletaking into account available 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 andinternally approved pricing practices.guidelines related to the performance obligations.
Recognition of revenue when, or as, the Company satisfies a performance obligation - The Company regularly reviews and update its VSOE and BESP information.satisfies performance obligations either over time or at a point in time as discussed in further detail below. Revenue is recognized at the time the related performance obligation is satisfied by transferring a promised good or service to a customer.
The relative selling price method allocates total arrangement consideration proportionallyDevice revenue - In transactions where the Company delivers hardware, the Company considers itself to each deliverable onbe 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 itemsprincipal in the arrangement.transaction and records revenue and costs of goods sold on a gross basis. Hardware revenue is generally recognized upon transfer of control to the customer.
A typical sales arrangement involves multiple elements, such as sales of badges, perpetual software licenses, professional services and maintenance services which entitle customers to unspecified upgrades, bug fixes, patch releases and telephone support.Software revenue - Revenue

from the saleCompany’s software products is generally recognized upon transfer of badges and perpetual software licensescontrol to the customer. Revenue is generally recognized upon shipment of hardware and software licenses.
Subscription and support revenue - The Company generates subscription and support revenue primarily from post contract support ("PCS") contracts, cloud-based subscription sales, and sales of extended warranties on the Vocera Badge. Subscription revenue is generally recognized ratably over the applicable term. The majority of software sales are in conjunction with PCS contracts, which generally have a one-year term. The Company recognizes revenue from PCS contracts ratably over the contractual service period. The service period typically commences upon transfer of control of the corresponding software products to the customer. The Company recognizes revenue from extended warranty contracts ratably over their contractual service period, which is primarily two years. This period starts one year from the date on which the transfer of control on the underlying hardware occurs because the hardware generally carries a one-year warranty.
Professional services and training revenue - Professional services and training revenue is generated when the Company installs and configures its software and devices at new or deliveryexisting customer sites. The Company recognizes revenue related to professional services as they are performed.
Contracts with multiple performance obligations - Some of the Company’s contracts with customers contain multiple performance obligations. For these contracts, the Company accounts for individual performance obligations separately if they are distinct. The transaction price is allocated to the separate performance obligations on a relative stand-alone selling price (SSP) basis. For deliverables that are routinely sold separately, such as subscription and support on the core offerings, the Company determines SSP by evaluating renewals over the trailing 12-months. For those that are not sold routinely, the Company determines SSP based on its overall pricing trends and objectives, taking into consideration market conditions and other factors, including the value of the contracts and the products sold.
Contract assets - The timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable are recorded 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 overinvoiced amount and in 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, but may take longer depending on the complexity of the work involved.  
For non-essential software arrangements with multiple deliverables, including license, professional services and maintenance, the Company recognizes license revenue usingdelivers goods or provides services or when the residual methodCompany’s right to consideration is unconditional. Payment terms on invoiced amounts are typically 30-45 days. The balance of accounting pursuant to relevant softwareaccounts receivable, net of allowance for doubtful accounts, as of December 31, 2021 and 2020 is presented in the accompanying consolidated balance sheets. In situations where revenue recognition guidance. Under the residual method, revenueoccurs before invoicing, an unbilled receivable is recognized when VSOE for fair value exists for allcreated, which represents a contract asset. As of the undelivered elementsDecember 31, 2021 and 2020 contract assets totaling $5.4 million and $4.2 million, respectively, were included in other receivables in the arrangement, but doesconsolidated balance sheet. Contract assets are evaluated for impairment whenever changes in events or changes in circumstances indicate that the carrying amount of such assets may not exist for one or more of the delivered elements in the arrangement. If evidence of fair value cannot be establishedrecoverable. There were no impairment losses incurred for the undelivered elements, allyears ended December 31, 2021 and 2020.

Revenue from sales-type leases
A portion of the Company's sales are made through multi-year lease agreements with customers. Sales-type leases are included in other receivables, accrued payroll and other current liabilities and other long-term liabilities on the consolidated balance sheets. When these arrangements are considered sales-type leases, upon delivery of leased products to customers, the Company recognizes revenue for such products in an amount equal to the net present value of the minimum lease payments. Unearned income is recognized as part of product revenue under the effective interest method. The Company recognizes revenue related to certain executory costs, including maintenance and extended warranty, ratably over the term of the underlying arrangements. The Company recognizes revenue related to battery refresh executory costs when such executory costs are incurred.
Proceeds from transfers of sales-type leases to third-party financial companies are allocated between the net investment in sales-type leases and the executory cost component for remaining service obligations based on relative present value. The difference between the amount of proceeds allocated to the net investment in lease and the carrying value of the net investment in lease is included in product revenue. Proceeds allocated to the executory cost component are accounted for as financing liabilities.


For the year ended December 31, 2017,2021, the Company transferred $0.9$0.5 million of lease receivables, recording an immateriala net loss of $0.1 million and $0.7$0.5 million of new financing liabilities for future performance of executory service obligations. For the year ended December 31, 2016,2020, the Company transferred $3.6$2.5 million of lease receivables, recording an immateriala net loss of $0.2 million and $1.6$2.0 million of new financing liabilities for future performance of executory service obligations.


For lease receivables retained as of December 31, 20172021 and 2016,2020, the Company recorded $1.3$0.4 million and $1.9$0.7 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 revenue in the consolidated statements of operations for all periods presented.
Research and development expenditures
Research and development costs are charged to operations as incurred. Software development costs incurred for external products prior to the establishment of technological feasibility are included in research and development and are expensed as incurred. After technological feasibility is established, material software development costs up to general availability of the software will beare 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,revenue, whichever is greater. To date, the time between the establishment of technological feasibility and general availability has been very short and therefore no significant costs have been incurred. Accordingly, the Company has not capitalized any software development costs related to research and development expenditures.

Advertising costs
Advertising costs are included in sales and marketing expense and are expensed as incurred. Advertising costs for the years ended December 31, 2017, 20162021, 2020 and 20152019 were immaterial.$0.7 million, $0.6 million, and $0.3 million, respectively.
Product warranties
The Company offers warranties on certain products and records a liability for the estimated future costs associated with warranty claims, which is based upon historical experience and the Company’s estimate of the level of future costs. The Company provides for the estimated costs of hardware warranties at the time the related revenue is recognized. Costs are estimated based on historical and projected product failure rates, historical and projected repair costs, and knowledge of specific product failures (if any). The specific hardware warranty includes parts and labor over a period generally ranging from one to three years. The Company provides no warranty for software. The Company regularly re-evaluates its estimates to assess the adequacy of the recorded warranty liabilities and adjust the amounts as necessary. Warranty costs are reflected in the consolidated statement of operations as cost of revenue.
Stock-based compensation
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.
For stock options issued to 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.
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 useuses 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
71

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, 20172021 and 2016,2020, respectively. Accordingly, the Company has recorded a full valuation allowance onagainst its deferred tax assets for these years.
At December 31, 2017,2021, the Company had a valuation allowance against net deferred tax assets of $45.3$61.5 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 are subject to adjustment by tax authorities and all years after 20102014 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, 2017, 20162021, 2020 and 2015,2019, 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, 2017, 20162020 and 2015,2019, the Company had revenue transactions with a related party, the University of Chicago Medical Center (UCMC)("UCMC"), for $0.4 million, $0.4$1.0 million and $0.4$1.3 million, respectively, relating to consulting services and technology solutions. One of the Company's board members iswas the President of UCMC.
Recently Adopted Accounting Pronouncement

In March 2016, the Financial Accounting Standards Board (FASB) issued new guidanceUCMC until her retirement in July of 2020 and as such, in 2021, UCMC is no longer deemed a related to accounting for stock-based payment award transactions. The guidance is designed to simplify several aspects of accounting for share-based payment awardparty. No material related party transactions including the income tax consequences, classification of awards as either equity or liabilities, classification on the statement of cash flows and forfeiture rate calculations. The guidance eliminates the requirement to delay the recognition of excess tax benefits until they reduce current taxes payable. Under this standard, previously unrecognized excess tax benefits shall be recognized on a modified retrospective basis. However, as of January 1, 2017, the previously unrecognized excess tax benefits of $10.4 million had no impact on the Company’s accumulated deficit balance as the related U.S. deferred tax assets were fully offset by a valuation allowance. The guidance also requires excess tax benefits and deficiencies to be recognized prospectively in the provision for income taxes rather than additional paid-in capital. The Company therefore determined that adoption of the new guidance had no material impact on the condensed consolidated statement of operations and the condensed consolidated statement of cash flows. Further, the new guidance eliminates the requirement to estimate forfeitures and reduce stock compensation expenseoccurred during the vesting period. Instead, companies can elect to account for actual forfeitures as they occur and record any previously unrecognized compensation expense for estimated forfeitures up to the period of adoption as a retrospective adjustment to beginning retained earnings. The Company has made the election to account for actual forfeitures as they occur starting in fiscal year 2017. During the year ended December 31, 2017, the Company recorded a retrospective adjustment to accumulated deficit of $0.4 million.2021.
RecentRecently adopted accounting pronouncements

In May 2014,August 2020, the FASB togetherissued ASU 2020-06 Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, related to the International Accounting Standards Board issued convergedaccounting for debt with conversion features. The amendments in this update simplify the accounting for convertible instruments by reducing the number of accounting models available for convertible debt instruments and convertible preferred stock. This update also amends the guidance for revenue recognition that will replace most existing guidance, eliminate industry-specific guidance and provide a unified modelthe derivatives scope exception 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 entity's own equity to reduce form-over-substance-based accounting conclusions and requires the application of the if-converted method for calculating diluted earnings per share. The update also requires entities to provide expanded disclosures about the terms and features of convertible instruments, how the instruments have been reported in the entity's financial statements and information about events, conditions and circumstances that can affect how to assess the amount that reflects the considerationor timing of an entity's future cash flows related to which the entity expects to be entitled in exchangethose instruments. The guidance is effective for interim and annual periods beginning after December 15, 2021 with early adoption permitted for fiscal years beginning after December 15, 2020, including interim periods within those goods or services.
The new guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application(modified retrospective method). 
fiscal years. The Company adopted the new guidance onbeginning January 1, 2018 using the full retrospective method, which requires the Company to present its historical financial information for fiscal years 2016 and 2017 as if the new revenue guidance had been applied to all prior periods. 
The most significant impact of the standard relates to the timing of revenue recognition for software licenses sold with professional services where the Company did not have vendor specific objective evidence (“VSOE”) for professional services under current guidance.  Under the new standard, the requirement to have VSOE for undelivered elements is eliminated and the Company will recognize revenue for software licenses upon transfer of control to its customers. Additionally, the new standard requires the

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

The adoption of the standard will resultthis guidance resulted in the recognitionan increase of additional revenue of $2.7$17.0 million and $4.3$15.2 million for the years ended December 31, 2017to convertible senior notes, net and 2016,accumulated deficit, respectively, an increasea reduction to additional paid-in capital of $32.2 million, a deferred tax liability of $4.4 million. The related valuation allowance was reversed upon adoption, resulting in gross profitno tax expense impact.

Table of $2.7 million and $4.3 million for the years ended December 31, 2017 and 2016, respectively, an increase (decrease) in sales and marketing expense of $0.1 million and $(1.5) million for the years ended December 31, 2017 and 2016, respectively, and a decrease in loss from operations of $2.6 million and $5.8 million for the years ended December 31, 2017 and 2016, respectively. In addition, the adoption of the standard will result in a decrease in total deferred revenue of $7.8 million and $5.2 million as of December 31, 2017 and 2016, respectively, driven primarily by the upfront recognition of software licenses sold with professional services for which the Company does not have VSOE, and an increase in total deferred commissions of $10.3 million and $10.4 million as of December 31, 2017 and 2016, respectively, which will be recognized in sales and marketing expense in future periods. The adoption of the standard will not have a significant impact to the provision for income taxes and will not have an impact on net cash provided by or used in operating, investing, or financing activities on the Company's consolidated statements of cash flows. See Expected Impact to Reported Results below for the impact of adoption of the standard on the Company's consolidated balance sheets and consolidated statements of operations.Contents

In February 2016, the FASB amended lease accounting requirements to begin recording assetsMarch 2020 and liabilities arising from leases on the balance sheet. The new guidance will also require significant additional disclosures about the amount, timing and uncertainty of cash flows from leases. This new guidance will be effective beginning on January 1, 2019 using a 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 determined the future effect of the standard on its financial position or results of operations.
In June 2016,2021, the FASB issued new guidance related to Reference Rate Reform. These pronouncements provide optional guidance for a limited period of time to ease the potential burden in accounting for credit losses(or recognizing the effects of) reference rate reform on instruments for both financial servicesreporting. The amendments in this update are elective and non-financial services entities.subject to meeting certain criteria, that have contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform. This could affect balances of right of use assets, lease liabilities, and notes payables. The new guidance introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. It also modifies the impairment model for available-for-sale debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. The guidance will be effective beginning January 1, 2020. Early adoption is permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements.
In October 2016, the FASB issued amended guidance on the accounting for income taxes. The new guidance requires the recognition of the income tax consequences of an intercompany asset transfer, other than transfers of inventory, when the transfer occurs.  The guidance will be effective for reporting periods beginning after December 15, 2017, with early adoption permitted. The Company is currently evaluating the impact of this new guidance on its consolidated financial statements, but does not expect that it will have a material impact on its consolidated financial statements.
In January 2017, the FASB issued new guidance which clarifies the definition of a business to assist companies with evaluating whether transactions should be accounted for as acquisitions of assets or businesses. The new guidance requires a company to evaluate if substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets; if so, the set of assets and activities is not a business. The guidance also requires a business to include at least one substantive process and narrows the definition of outputs by more closely aligning it with how outputs are describedamendments in the guidance for revenue from contracts with customers. The new guidance will beMarch update are effective foras of March 12, 2020 through December 21, 2022 and the Companyamendments in the first quarter of 2018. Early adoption is permitted. The guidance should be applied prospectively to any transactions occurring within the period of adoption.January update are effective immediately for all entities. The adoption of this guidance isthese pronouncements did not expected to have a material impact on the Company’s consolidated financial statements.
Recently issued and not yet adopted accounting pronouncements
In January 2017,October 2021, the FASB issued new guidance to simplify the accountingASU No. 2021-08, Business Combinations (Topic 805): Accounting for goodwill impairment. The guidance simplifies the measurement of goodwill impairment by removing step 2 of the goodwill impairment test, Contract Assets and Contract Liabilities from Contracts with Customers which requires the determinationrecognition and measurement of contract assets and contract liabilities acquired in a business combination in accordance with ASC 606, Revenue from Contracts with Customers. Considerations used to determine the amount of contract assets and contract liabilities to record at the acquisition date include the terms of the fair valueacquired contract, such as timing of individual assetspayment, identification of each performance obligation in the contract, and liabilitiesallocation of the contract transaction price to each identified performance obligation on a reporting unit.relative standalone selling price basis as of contract inception. ASU 2021-08 is effective for the Company beginning in the first quarter of fiscal year 2023. The new guidance requires goodwill impairment to be measured as the amount by which a reporting unit’s carrying value exceeds its fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. The amendments should be applied prospectively for acquisitions occurring on a prospective basis.  The new

Early adoption of the proposed amendments is effective for fiscal years beginning after December 15, 2019 with earlypermitted, including adoption permitted forin an interim or annual goodwill impairment tests performed after January 1, 2017.period. The Company is evaluatingcurrently assessing the impact of this new accounting guidance will have on its consolidated financial statements.
In May 2017, the FASB amended the scope
2.Revenue, deferred revenue and deferred commissions
Disaggregation of modification accounting for share-based payment arrangements. The guidance clarifies the type of changes to terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting. Specifically, under this guidance, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The new standard is effective for the Company in the first quarter of 2018. Early adoption is permitted. The guidance will be applied prospectively to awards modified on or after the adoption date. The Company does not expect the guidance to have a material impact on its consolidated financial statements.Revenue

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

Costs to obtain and fulfill a contract

The Company capitalizes certain incremental contract acquisition costs consisting primarily of commissions paid and the related payroll taxes when customer contracts are signed. The Company determines whether costs should be deferred based on its sales compensation plans, if the commissions are incremental and would not have been incurred absent the execution of the customer contract. Sales commissions for renewals of customer contracts are not commensurate with the commissions paid for the acquisition of the initial contract given the substantive difference in commission rates in proportion to their respective contract values. Commissions paid upon the initial acquisition of a contract are amortized over the estimated period of benefit, which may exceed the term of the initial contract. Accordingly, amortization of deferred costs is recognized on a systematic basis that is consistent with the pattern of revenue recognition allocated to each performance obligation and is included in sales and marketing expense in the consolidated statements of operations. The Company determines its estimated period of benefit, up to five years, by evaluating the expected renewals of its customer contracts, the duration of its relationships with its
73

customers, average life of the Company's technology, and other factors. Deferred costs are periodically reviewed for impairment. In accordance with Topic 340, an entity may elect a practical expedient that allows the entity to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset that the entity otherwise would have recognized is one year or less. The Company has elected this practical expedient and recognizes costs paid to obtain contracts as expense when incurred. Changes in the balance of total deferred commissions (contract asset) during the year ended December 31, 2021 and 2020 were as follows:
(in thousands)December 31, 2020AdditionsCommissions RecognizedDecember 31, 2021

Deferred commissions$10,477 $10,469 $(8,653)$12,293 

Deferred revenue
The Company records deferred revenue when cash payments are received in advance of the performance under the contract. The current portion of deferred revenue represents the amounts that are expected to be recognized as revenue within one year of the consolidated balance sheet date.
Revenue recognized during the year ended December 31, 2021 from deferred revenue balances as of December 31, 2020 was $60.4 million. Revenue recognized during the year ended December 31, 2020 from deferred revenue balances as of December 31, 2019 was $53.4 million.
The “contracted but not recognized” performance obligations represent the Company’s deferred revenue and non-cancelable backlog amounts. This balance as of December 31, 2021 was $200.1 million, of which the Company expects to recognize approximately 65% of the revenue over the next 12 months and the remainder thereafter.

3.Fair value of financial instruments
The Company’s cash, cash equivalents and short-term investments approximateare carried at their fair value due tovalues with any differences from their short-term nature.amortized cost recorded in equity as unrealized gains (losses) on marketable securities. As a basis for determining the fair value of its assets and liabilities, the Company utilizesfollows 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, 2017, 20162021, 2020 and 2015,2019, 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'sCompany’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'sCompany’s Level 2 fixed income securities areis 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.
In addition to its cash, cash equivalents and short-term investments, the Company measures the fair value of its Convertible Senior Notes on a quarterly basis for disclosure purposes. The Company does not have anyconsiders the fair value of the Convertible Senior Notes at December 31, 2021 to be a Level 2 measurement due to limited trading activity of the Convertible Senior Notes. Refer to Note 8 to the consolidated financial instrumentsstatements for further information.
The agreement for the acquisition of EASE includes contingent payments to the owners of EASE, payable based on achievement of post-acquisition financial metrics. This contingent consideration is a Level 3 fair value measurement, and the valuation of the Company’s contingent consideration obligation was estimated as the present value of total expected contingent consideration payments which are valueddetermined using Level 3 inputs.a Monte Carlo simulation. This analysis reflects the contractual terms of the purchase agreements and utilizes assumptions with regard to future sales, probabilities of achieving such future sales, the
74

likelihood and timing of expected payments and a discount rate. Significant increases with respect to assumptions as to future sales and probabilities of achieving such future sales would result in a higher fair value measurement, while an increase in the discount rate would result in a lower fair value measurement. The unobservable inputs in the valuation include revenue volatility of 10%, a risk-free rate of 2.50%. The fair value adjustment for the contingent consideration of $2.9 million for the year ended December 31, 2021 was recorded as other income and expense.
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, 20172021 and 2016,2020, respectively. There were no liabilities measured at fair value on a recurring basis for these dates.

Goodwill
The Company had $49.2 $94.9 million and $49.2$69.2 million of goodwill as of December 31, 20172021 and 2016,2020, respectively. The addition to goodwill during the year ended December 31, 2021 of $25.7 million was based on the purchase price allocations of the acquisition completed in May of 2021 (See Note 12). 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, 2017 $41.2 million of the Company's goodwill resides in the Product reporting unit and $8.0 million resides in the Servicea single reporting unit. The Company performed an impairment assessment in 2017 which determined that no impairment existed. For 2017existed as of December 31, 2021 and 2016,2020. To assess goodwill for impairment for the years ended December 31, 2021 and 2020, the Company used the qualitative assessment permitted under authoritative accounting guidance. Among the qualitative factors considered were changes since the prior impairment test in the following: industry and competitive environment, business

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.

8.Convertible Senior Notes
Convertible Senior Notes due 2026
In March 2021, the Company issued $200.0 million in aggregate principal amount of its 0.50% Convertible Senior Notes, due 2026 (the “2026 Notes”). The 2026 Notes are unsecured, unsubordinated obligations of the Company and bear interest at a fixed rate of 0.50% per annum, payable semi-annually in arrears on March 15 and September 15 of each year, commencing on September 15, 2021. The 2026 Notes mature on September 15, 2026, unless converted, redeemed or repurchased in accordance with their terms prior to such date. The Company granted the initial purchasers an overallotment option under the purchase agreement to purchase up to an additional $30.0 million aggregate principal amount of the 2026 Notes to cover overallotments within a 30-day period. The purchasers partially exercised the overallotment option in April 2021 and the Company issued an additional $24.5 million of the 2026 Notes. The Company may not redeem the 2026 Notes prior to March 20, 2024. The Company may redeem for cash all or any portion of the 2026 Notes (subject to the partial redemption limitation (as defined in the indenture governing the 2026 Notes)), at its option, on or after March 20, 2024 if the last reported sale price of common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the

trading day immediately preceding the date on which the Company provides a redemption notice at a redemption price equal to 100% of the principal amount of the 2026 Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date.
The 2026 Notes are convertible into cash, shares of Company’s common stock or a combination of cash and shares of common stock, at the Company’s election, at an initial conversion rate of 16.6272 shares of common stock per $1,000 principal amount of the 2026 Notes, which is equal to an initial conversion price of approximately $60.14 per share of common stock. The 2026 Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding June 15, 2026, only under the following circumstances:
(1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2021 (and only during such calendar quarter), if the last reported sale price of common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price of the 2026 Notes on each applicable trading day
(2) during the 5 business day period after any 10 consecutive trading day period in which the trading price per $1,000 principal amount of the 2026 Notes for each trading day of that 10 day consecutive trading day period was less than 98% of the product of the last reported sale price of common stock and the conversion rate of the 2026 Notes on such trading day;
(3) if the Company calls any or all of the 2026 Notes for redemption, at any time prior to the close of business on the second scheduled trading day prior to the applicable redemption date; or
(4) upon the occurrence of specified corporate events.
On or after June 15, 2026, holders of the 2026 Notes may convert all or any portion of their 2026 Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date, regardless of the foregoing circumstances. If a fundamental change occurs (as set forth in the indenture governing the 2026 Notes), each holder of the 2026 Note shall have the right, at such holder’s option, to require the Company to repurchase for cash all of such their Notes, or any portion of the principal amount, at a repurchase price equal to 100% of the principal amount thereof, plus accrued and unpaid interest. During the year ended December 31, 2021, the conditions allowing holders of the 2026 Notes to convert have not been met and there were no changes to the initial conversion price of the 2026 Notes. The 2026 Notes are not convertible during the year ended December 31, 2021 and are classified as long-term debt.
In accounting for the 2026 Notes after adoption of ASU 2020-06, the 2026 Notes are accounted for as a single liability. The carrying amount of the liability component for 2026 Notes is $218.6 million as of December 31, 2021, with principal of $224.5 million, net of unamortized issuance costs of $5.9 million. The costs related to the 2026 Notes are being amortized to interest expense over the contractual term of the 2026 Notes at an effective interest rate of 1.05%.
The 2026 Notes and related interest expense consist of the following:

2026 Capped Calls
In connection with the pricing of the 2026 Notes, the Company entered into privately negotiated capped call transactions with certain counterparties (the “2026 Capped Calls”). The 2026 Capped Calls have an initial strike price of $60.14 per share, subject to certain adjustments, which correspond to the initial conversion price of the 2026 Notes. The 2026 Capped Calls have initial cap prices of $77.96 per share, subject to certain adjustments. Conditions that cause adjustments to the initial strike price of the 2026 Capped Calls mirror conditions that result in corresponding adjustments for the 2026 Notes. The 2026 Capped Calls are generally intended to reduce or offset the potential dilution to the Company’s common stock upon any conversion of the 2026 Notes with such reduction or offset, as the case may be, subject to a cap based on the cap price. For accounting purposes, the 2026 Capped Calls are separate transactions, and not part of the terms of the 2026 Notes. As these transactions meet certain accounting criteria, the 2026 Capped Calls are recorded in stockholders' equity at an amount of $17.4 million and are not accounted for as derivatives. In connection with the partial exercise of the overallotment option and the issuance by the Company of $24.5 million of 2026 Notes on April 5, 2021, the Company entered into $1.9 million of additional privately negotiated capped calls with the same terms as the initial capped calls.
Convertible Senior Notes due 2023
In May 2018, the Company issued $143.8 million aggregate principal amount of 1.50% Convertible Senior Notes due May 15, 2023 (the “2023 Notes”), including $18.8 million aggregate principal amount of such notes pursuant to the exercise in full of options granted to the initial purchasers. The 2023 Notes are unsecured, unsubordinated obligations and bear interest at a fixed rate of 1.50% per annum, payable semi-annually in arrears on May 15 and November 15 of each year, commencing on November 15, 2018. The total net proceeds from the offering, after deducting initial purchase discounts and estimated debt issuance costs, were approximately $138.9 million.
In the first quarter of 2021, the Company used part of the net proceeds from the issuance of the 2026 Notes to retire $102.9 million aggregate principal amount of the 2023 Notes in privately negotiated transactions for consideration of $102.9 million in cash and 1,277,731 shares of the Company’s common stock (the "2023 Note Repurchase Transactions"). The Company separately settled the accrued interest of approximately $0.5 million associated with the retired 2023 Notes in cash.
Out of the common stock issued, the Company provided additional issuance of 46,216 shares of the Company’s common stock not provided for under the original conversion terms of the 2023 Notes to induce the holders of the 2023 Notes to agree to the retirement. The Company used cash to settle the principal of the retired 2023 Notes and issued common stock to settle the conversion spread.

The 2023 Note Repurchase Transactions met the requirements to be accounted for as an induced conversion. Under the induced conversion guidance, the total fair value of the additional cash and common stock issued to induce conversion is recognized as an inducement expense. The remaining cash and common stock consideration issued under the original terms of the 2023 Notes are accounted for under the general conversion accounting guidance. The 2023 Note Repurchase Transactions resulted in a $2.1 million inducement loss equal to the fair value of the additional common stock issued for inducement and the difference of approximately $1.6 million between the carrying amount of the 2023 Notes retired, including debt issuance costs of $1.6 million, and the cash consideration paid, and the par amount of the common stock issued was recorded in additional paid-in capital.

Each $1,000 principal amount of the remaining 2023 Notes is initially convertible into 31.0073 shares of the Company’s common stock (the “2023 Notes Conversion Option”), which is equivalent to an initial conversion price of approximately $32.25 per share, subject to adjustment upon the occurrence of specified events. The 2023 Notes will be convertible at the option of the holders at any time prior to the close of business on the business day immediately preceding February 15, 2023, only under the following circumstances:
(1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2018 (and only during such calendar quarter), if the last reported sale price of the Company common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price of the 2023 Notes on each applicable trading day;
(2) during the 5 business day period after any 10 consecutive trading day period in which the trading price per $1,000 principal amount of the 2023 Notes for each day of that 10 day consecutive trading day period was less than 98% of the product of the last reported sale price of the Company’s common stock and the conversion rate of the 2023 Notes on such trading day; or
(3) upon the occurrence of specified corporate events (as set forth in the indenture governing the 2023 Notes).

Table of Contents
For at least 20 trading days during the period of 30 consecutive days ended December 31, 2021, the last reported sale price of the Company’s common stock was equal to or exceeded 130% of the conversion price of the 2023 Notes on each applicable trading day. As a result, the 2023 Notes are convertible at the option of the holders during the fiscal quarter ending December 31, 2021; and were classified as current liabilities on the balance sheet as of December 31, 2021.
On or after February 15, 2023 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert their 2023 Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of the Company’s common stock or a combination of cash and shares of the Company’s common stock, at the Company’s election. If certain specified fundamental changes occur (as set forth in the indenture governing the 2023 Notes) prior to the maturity date, holders of the 2023 Notes may require the Company to repurchase for cash all or any portion of their Notes at a repurchase price equal to 100% of the principal amount of the 2023 Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date. In addition, if specific corporate events occur prior to the applicable maturity date, the Company will increase the conversion rate for a holder who elects to convert their notes in connection with such a corporate event in certain circumstances.
Prior to the adoption of the ASU 2020-06 on January 1, 2021 and in accounting for the issuance of the 2023 Notes, the 2023 Notes were separated into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar debt instrument that does not have an associated conversion feature. The carrying amount of the equity component representing the 2023 Conversion Option was $33.4 million and was determined by deducting the fair value of the liability components from the par value of the 2023 Notes. The equity component was recorded in additional paid-in-capital and was not re-measured as long as they continued to meet the conditions for equity classification. The excess of the principal amount of the liability component over its carrying amount (the “Debt Discount”) was amortized to interest expense over the contractual term of the 2023 Notes at an effective interest rate of 7.6%.
Prior to the adoption of the ASU 2020-06 on January 1, 2021 and in accounting for the debt issuance costs of $4.9 million related to the 2023 Notes, the Company allocated the total amount incurred to the liability and equity components of the 2023 Notes based on their relative values. Issuance costs attributable to the liability component were $3.8 million and were amortized to interest expense using the effective interest method over the contractual term of the 2023 Notes. Issuance costs attributable to the equity components were netted with the equity component in additional paid-in-capital.
The Company elected to early adopt ASU 2020-06 as of January 1, 2021 based on a modified retrospective transition method. Under such transition, prior-period information has not been retrospectively adjusted.
In accounting for the 2023 Notes after adoption of ASU 2020-06, the 2023 Notes are accounted for as a single liability. The carrying amount of the liability component for 2023 Notes is $40.4 million as of December 31, 2021, with principal of $40.8 million, net of debt issuance cost of $0.4 million. The issuance costs related to the 2023 Notes are being amortized to interest expense over the contractual term of the 2023 Notes at an effective interest rate 2.19%.

The total estimated fair value of the 2023 and 2026 Notes ("the Notes") as of December 31, 2021 was approximately $365.1 million. The fair value was determined based on the closing trading price per $1,000 of the Notes as of the last day of trading for the period. The fair value of the Notes is primarily affected by the trading price of the Company’s common stock and market interest rates.
2023 Capped Calls
In connection with the pricing of the 2023 Notes, the Company entered into privately negotiated capped call transactions with certain counterparties, the “2023 Capped Calls.” The 2023 Capped Calls entered into with the 2023 Notes are still outstanding and each have an initial strike price of approximately $32.25 per share, subject to certain adjustments, which correspond to the initial conversion price of the 2023 Notes. The 2023 Capped Calls have initial cap prices of $38.94 per share, subject to certain adjustments. The 2023 Capped Calls cover, subject to anti-dilution adjustments, approximately 4.5 million shares of the Company’s common stock. Conditions that cause adjustments to the initial strike price of the Capped Calls mirror conditions that result in corresponding adjustments for the 2023 Notes. The 2023 Capped Calls are generally intended to reduce or offset the potential dilution to the Company’s common stock upon any conversion of the 2023 Notes with such reduction or offset, as the case may be, subject to a cap based on the cap price. For accounting purposes, the 2023 Capped Calls are separate transactions, and not part of the terms of the 2023 Notes. As these transactions meet certain accounting criteria, the 2023 Capped Calls are recorded in stockholders' equity and are not accounted for as derivatives. The cost of $8.9 million incurred in connection with the 2023 Capped Calls was recorded as a reduction to additional paid-in capital. The 2023 Capped Calls were not impacted by the 2023 Note Repurchase Transactions and continue to remain outstanding.
The net impact to the Company’s stockholders' equity, included in additional paid-in capital, of the above components of the 2023 Notes is as follows:

Impact on Earnings Per Share
Prior to the adoption of ASU 2020-06, the Company used the treasury stock method for calculating any potential dilutive effect of the conversion spread of its 2023 Notes. Under the treasury stock method, in periods when the Company reports net income, the Company is required to include the effect of additional shares that may be issued under the 2023 Notes when the price of its’ common stock exceeds the conversion price. The conversion spread on the 2023 convertible senior notes had an anti-dilutive impact during the year ended December 31, 2021, since the average market price of the Company’s common stock during the period did not exceed the initial conversion price per share for the 2023 Notes and the Company was in a net loss position.

After the adoption of ASU 2020-06, the Company uses the if-converted method for calculating any potential dilutive effect of its 2023 Notes and 2026 Notes for the year ended December 31, 2021. Under this method, diluted earnings per share would generally be calculated assuming that all the 2023 and 2026 Notes were converted solely into 5.0 million shares of common stock at the beginning of the reporting period, unless the result would be antidilutive. The potential shares of common stock issuable upon the conversion of the 2023 and 2026 Notes were excluded from the calculation of diluted net loss per share for the year ended December 31, 2021 because their effect was anti-dilutive as of December 31, 2021.

The Company currently has directors and officers insurance. As there has been no significant history of losses, no expense accrual has been made.

10.Common Stock and Share-based Compensation
The Company’s certificate of incorporation, as amended, authorizes the Company to issue 100 million shares of $0.0003 par value common stock.
At December 31, 2017,2021, the Company has 1,297,0721,205,378 shares of common stock reserved for issuance under stock option plans.
Incentive stock option plans
The Company has four6 equity incentive plans: the 2000 Stock Option Plan (the “2000 Plan”("the 2000 Plan"), the 2006 Stock Option Plan (the “2006 Plan”("the 2006 Plan"), the 2012 Stock Option Plan (the “2012 Plan”("the 2012 Plan") and, the 2016 Equity Inducement Plan ("the 2016 Plan") and the 2020 Equity Inducement Plan ("the 2020 Plan") and the 2021 Equity Incentive plan (the "2016 Plan"“2021 Plan”). On March 26, 2012, allAll shares that were previously reserved under the 2006 Plan and 2012 Plan but not subject to outstanding awards became available for grant under the 20122021 Plan. No additional shares will be issued under the 2006 Plan or 2012 Plan. The 2000 Plan terminated in March 2010 and no additional shares will be issued under this plan. All options currently outstanding under the 2000 Plan and the 2006 Plan continue to be governed by the terms and conditions of those plans. The 2016 Plan wasand 2020 Plan were adopted by the Company's Board of Directors without shareholder approval pursuant to the inducement exemption provided under the NYSE listing rules for the issuance of restricted stock units ("RSUs") to employee's who joined the Company after the acquisitionacquisitions of Extension Healthcare.Healthcare and Ease.

Under the 20122021 Plan, the Company has the ability to issue incentive stock options (“ISOs”("ISOs"), stock appreciation rights, restricted stock awards, RSUs, performance awards and stock bonuses. The ISOs will be granted at a price per share not less than the fair value at date of grant.
Valuation Assumptions
Compensation expense for all share-based payment awards, including stock options, restricted stock units (“RSUs”), and performance stock units (“PSUs”), is measured based on the estimated fair value of the award on the grant date over the related vesting or performance periods.
We estimate the fair value of our stock-based awards as follows:
Restricted Stock Units. The fair value of restricted stock units is determined based on the quoted market price of our common stock on the date of grant.

Performance Stock Units. Performance stock units consist of grants of performance-based restricted stock units to certain members of executive management that vest contingent upon the achievement of pre-determined market and service conditions (referred to herein as “performance stock units”). The fair value of our performance stock units is estimated using a Monte-Carlo simulation model which is a probabilistic approach for calculating the fair value of the awards. The Monte-Carlo simulation is a statistical technique used, in this instance, to simulate future stock prices of the Company relative to constituents in the S&P 600 Health Care Equipment and Services Index. Key assumptions for the Monte-Carlo simulation model are the risk-free interest rate, expected volatility, expected dividends and correlation coefficient.
Stock Options and Employee Stock Purchase Plan. The fair value of stock options and stock purchase rights granted pursuant to new hires generally vest over a 4-year period with 25% vestingour equity incentive plans and our ESPP, respectively, is estimated using the Black-Scholes valuation model based on the multiple-award valuation method. Key assumptions of the Black-Scholes valuation model are the risk-free interest rate, expected volatility, expected term and expected dividends. The risk-free interest rate is based on U.S. Treasury yields in effect at the endtime of one yeargrant for the expected term of the option. Expected volatility is based on a combination of historical stock price volatility. An expected term is estimated based on historical exercise behavior, post-vesting termination patterns, options outstanding 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.future expected exercise behavior.

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 employee stock-based compensation:
Year ended December 31,
2015
Expected term (in years)5.39
Volatility41.3% - 41.8%
Risk-free interest rate1.62% - 1.63%
Dividend yield0.0%
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)ESPP program allows eligible employees to purchase shares of common stock at a discount through payroll deductions of up to 15% of their eligible compensation, subject to any plan limitations. The ESPP provides for six-month offering periods.
At the end of each offering period, eligible employees are able to purchase shares at 85% of the lower of the fair market value of the Company's common stock on the first trading day of the offering period or on the last day of the offering period. During the years ended December 31, 20172021 and 2016,2020, employees purchased 159,532149,617 and 188,372240,593 shares, respectively, of common stock at an average purchase price of $17.23$27.74 and $8.97,$15.54, respectively. As of December 31, 2017, 584,6082021, 1,126,334 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:

At December 31, 2017,2021, there was $28.1$52.8 million of unrecognized compensation cost related to RSUs and PSUs, which is expected to be recognized over a weighted-average period of 1.711.68 years.
During the third quarter of this fiscal year 2021 and the second quarter of fiscal year 2020 the Company granted 144,523 and 145,877 PSUs, respectively to certain executives under the 2021 Equity Incentive plan (the “2021 Plan”) and the 2012 Equity Incentive Plan (the “2012 Plan”), respectively. PSUs are contingent on the achievement of our comparative market-based returns. On the date of grant, the fair value of the total shareholder return (TSR) component of the PSUs is estimated using a Monte Carlo valuation model. The PSUs will vest over an approximate three-year performance period. The number of shares the PSU holder receives is based on the extent to which the corresponding market conditions have been achieved. For awards subject to service and market conditions, the number of shares of our stock issued pursuant to the award can range from 0% to 200% of the target amount. Compensation expense for awards with performance-based and service-based conditions is recognized over the requisite service period. These grants were reduced from shares of common stock reserved for issuance under stock plans as if 200% of the target amount were achieved. The assumptions used to determine the fair value are level 3 fair value measurements which include unobservable inputs that are significant to the measurement of the fair value of the assets or liabilities that are supported by little or no market data.
The assumptions used in the Monte Carlo valuation model to value the PSUs were as follows:

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.award and forfeitures are recognized as incurred. For the yearyears ended December 31, 20172021, 2020 and 2019 the straight-line amortization is reduced by actual forfeitures. For the years ended December 31, 2016 and 2015 the straight-line amortization has been reduced for estimated forfeitures. The Company estimated the expected forfeiture rate based on its historical experience, considering voluntary termination behaviors, trends of actual award forfeitures, and other events that will impact the forfeiture rate. To the extent the Company’s actual forfeiture rate is different from the estimate, the stock-based compensation expense is adjusted accordingly.

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 following table presents a summary of the operating segments:

As of December 31, 2021 and 2020, the Company has provided a valuation allowance against certain federal and state deferred tax assets. Management continues to evaluate the realizability of deferred tax assets and the related valuation allowance. If management’s assessment of the deferred tax assets or the corresponding valuation allowance were to change, the Company would record the related adjustment to income during the period in which management makes the determination.
On August 18, 2020, as part of the acquisition of EASE Applications, the Company recorded $2.1 million in deferred tax liabilities, related to the intangible assets acquired. Changes in the acquiring company’s deferred tax assets or liabilities subsequent to a business combination are required to be recorded in income during the period in which the transaction occurs. The Company was able to offset these deferred tax liabilities with a release of a portion of the Company’s valuation allowance. Accordingly, the $2.1 million decrease in the Company’s net deferred tax assets resulted in the release of a corresponding $2.1 million valuation allowance and recognition of a tax benefit for the year ended December 31, 2020.
On March 27, 2020, the Coronavirus Aid, Relief and Economic Security Act ("CARES Act") was enacted and signed into law. The CARES Act, among other things, permits net operating loss carryovers and carrybacks to offset 100% of taxable income for taxable years beginning before 2021. The Company has determined that the net operating loss provisions of the CARES Act will not result in a material benefit to the Company since the Company has been generating taxable losses.
In addition, the CARES Act allows for the deferral of payment on the Company's share of the 6.2% Social Security tax on wages paid beginning on March 27, 2020 and ending on December 31, 2020. Deferred amounts are payable in two installments, with 50% of such taxes totaling $0.9 million due on December 31, 2021, and the remainder of $0.9 million due on December 31, 2022. The first installment in the amount of $0.9 million has been paid as of December 31, 2021.

The Company's deferred tax liabilities are primarily related to tax deductible goodwill. The Company determines its valuation allowance on deferred tax assets by considering both positive and negative evidence in order to ascertain whether it is more likely than not that deferred tax assets will be realized. Realization of deferred tax assets is dependent upon the generation of future taxable income, if any, the timing and amount of which are uncertain. Due to the history of losses the Company has generated in the past, the Company believes that it is not more likely than not that all of the deferred tax assets in the U.S. and Canada can be realized as of December 31, 2017;2021; accordingly, the Company has recorded a full valuation allowance onagainst its deferred tax assets.
On December 22, 2017, the Tax Cuts and Jobs Act (P.L. 115-97) was signed into law. Among other changes is a permanent reduction in the federal corporate income tax rate from 35% to 21% effective January 1, 2018. As a result of the reduction in the corporate income tax rate, the Company has revalued its net deferred tax liability at December 31, 2017. This resulted in a reduction in the value of the Company's net deferred tax asset of approximately $19.0 million, which is offset by the change in valuation allowance of $19.7 million. This resulted in a deferred tax benefit of $0.7 million recorded in the statement of operations in the three months ending December 31, 2017.
The Company’s valuation allowance increased by $2.9$21.6 million and $6.4increased by $0.5 million for the years ended December 31, 20172021 and 2016,2020, respectively. The change in the 20172021 valuation allowance was primarily due to the addition of current year loss carryforwards and federal rate reduction.loss carryforwards from the PatientSafe acquisition. The change in the 20162020 valuation allowance was primarily due to the addition of current year loss carryforwards.carryforwards and EASE acquisition related tax benefits.
At December 31, 2017,2021, the Company had $113.9$176.7 million and $56.5$151.8 million, respectively, of federal and state net operating loss carryforwards. The federal net operating loss carryforward generated in the years ended December 31, 2002 through 2017 begin expiring in 2022.
Net operating losses originating before January 1, 2018 are eligible to offset taxable income, if not otherwise limited under IRS Section 382. Net operating losses generated after December 31, 2017 have an indefinite carryforward period and subject to 80% deduction limitation based upon pre-net operating deduction taxable income. The CARES Act temporarily removes the 80% taxable income limitation for tax years beginning before 2021. Furthermore, it allows for a five-year carryback of Federal net operating losses that arose in 2020, 2019, and 2018.
In addition, the Company has federal research and development tax credits carryforwards of approximately $3.1$7.6 million and state research and development tax credit carryforwards of approximately $4.8$10.1 million. The federal credit carryforwards begin expiring

in 2026 and the state credits carry forward indefinitely. The Internal Revenue Code (IRC) contains provisions which limit the amount of net operating loss (NOL)("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, 2017, $11.52021, $1.1 million of the Company's NOL carryovers and $0.5 million of creditnet operating loss 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.$0.6 million.

As a result of the Company’s historical losses and related valuation allowances, the Company has recorded substantially all of the uncertain tax amounts above as reductions to deferred tax assets which are subject to a full valuation allowance in its consolidated balance sheet with an insignificant portion recorded in other long-term liabilities. The Company recognizes interest and penalties relating to uncertain tax positions in income tax expense. As the Company is not currently under examination, it is reasonable to assume that the balance of gross unrecognized tax benefits will likely not change in the next twelve months.
The Company files income tax returns in the United States on a federal basis and in various states. The Company is not currently under any international or any United States federal, state and local income tax examinations for any taxable years. All of the Company’s net operating losses and research credit carryforwards prior to 20172021 are subject to tax authority adjustment and all years after 20102014 are still subject to the tax authority examinations.

Acquisition of Extension HealthcarePatientSafe Solutions, Inc.
On October 27, 2016,May 4, 2021, the Company acquired all of the outstanding equity interest of Extension HealthcarePatientSafe for $52.5approximately $36.0 million in cash. The Company incurred $5.8 million in mergercash, net of cash acquired of $0.2 million. PatientSafe provides a clinical communication and integration costscollaboration (CC&C) solution for the year ended December 31, 2016, which were recorded in cost of revenue and operating expensessmartphones that is engineered to run in the consolidated statementscloud.

Total liabilities6,434 
Net assets acquired$36,000 
The estimated fair values of identifiable customer relationship and backlog intangible assets were primarily determined using discounted cash flow models and the fair value of developed technology was determined using the relief-from-royalty method. The estimation of the fair value of the intangible assets required the use of valuation techniques and entailed consideration of all the relevant factors that might affect the fair value, such as present value factors, estimates of future revenues and costs, and applicable royalty rates. The amortization of developed technology and backlog intangibles are recorded in "cost of revenues" for product and the amortization for customer relationship intangibles is recorded in "sales and marketing" expenses on the consolidated statement of operations.

The excess of the acquisition consideration over the fair values of the underlying net assets acquired was recorded as goodwill. Goodwill is largely attributed to the synergy of PatientSafe’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 is instead tested for impairment at least annually or more frequently if indicators of impairment are present. The goodwill acquired as part of the acquisition is not deductible for tax purposes.

The Company incurred $3.9 million of acquisition-related costs in the year ended December 31, 2021 that were expensed as incurred. These costs are recorded as general and administrative expenses in the consolidated statement of operations.
The acquisition did not result in material contributions to revenue in the consolidated financial statements for the year ended December 31, 2021 and due to the continued integration of the combined businesses, it was impractical to determine the impact of the acquisition on earnings. Additionally, pro forma financial information is not provided for consolidated revenue and net income as such amounts attributable to PatientSafe were insignificant to the Company’s consolidated financial statements taken as a whole.

Acquisition of EASE Applications, LLC
On August 18, 2020, the Company acquired all of the outstanding equity interest of EASE Applications for $24.2 million in cash, net of $0.3 million of cash acquired. EASE Applications, now called Vocera Ease, offers a cloud-based communication platform and mobile application built to improve the patient experience by enabling friends and family members to receive timely updates about the progress of their loved one in the hospital. Vocera Ease enables nurses and other care team members to send Health Insurance and Portability and Accountability Act ("HIPAA")-compliant texts, photos, and video updates to patients’ loved ones, putting them at ease and saving valuable time. With this acquisition, Vocera further strengthened its ability to fulfill its mission to improve the lives of patients, families and care teams.

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

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

The goodwill recorded from the acquisition of Extension Healthcare was allocated with $31.2 million attributableagreement also included contingent payments to the Product reporting unitowners of EASE Applications, payable based on achievement of post-acquisition financial metrics as of December 31, 2021 and $8.0December 31, 2022. If these financial metrics were to be achieved the Company would have owed additional consideration of $2.5 million attributable to the Service reporting unit.
Inas of December 31, 2021 and 2022. This contingent consideration was fair valued in connection with the acquisition the Company recorded a charge of $2.6 million related to the planned redistribution of proceeds by the selling shareholders to employees of Extension Healthcare who will be retained by the Company post-acquisition. ("Employee Payments"). These payments are not dependent on continued employment with the Company and will be reduced by any escrow claims made by the Company prior to redistribution. Under GAAP, including guidance promulgated by the U.S. Securities and Exchange Commission, actions of economic interest holdersresulted in a company may be imputed to the company itself. The selling shareholdersliability of Extension Healthcare meet the criteria of economic interest holders$2.2 million as of the acquisition date. The fair value of contingent consideration was $0.1 million and $3.0 million as of December 31, 2021 and 2020, respectively (See Note 3). The estimated fair value was determined using a Monte Carlo valuation model.

The Company due to their ability to earn additional consideration in connection with the closeincurred $0.6 million of escrow. As such, the redistribution of this portion of the purchase price to the acquired employees who did not have a right to such payments based on their existing interest in Extension Healthcare at the time of acquisition are deemed to represent payments for servicesacquisition-related costs that benefit the Company and must therefore bewere expensed as incurred. These costs were recorded as non-cash compensation expense incurred bygeneral and administrative expenses in the Company and a capital contribution received from the selling shareholders.

Additionally, in connection with the acquisition the Company established a retention bonus plan for Extension Healthcarecontinuing EASE Applications employees with potential additional compensation over a two-year period of approximately $2.6$5.0 million, based on achievement of financial metrics and continued employment.

____________________
(1) Mr. Spencer left the company in June 2021.

The compensation provided to our named executive officers for 2021 is incorporatedset forth in detail in the Summary Compensation Table and other tables that follow this section, as well as the accompanying footnotes and narrative discussions relating to those tables. This section also discusses our executive compensation philosophy, objectives and design; how and why the Compensation Committee arrived at the specific compensation policies and decisions for our named executive officers during 2021; the role of Compensia, our outside compensation consultant for executive compensation decisions for 2021; and the peer companies used in evaluating executive officer compensation.

Executive Compensation Philosophy, Objectives and Design

Philosophy

We operate in a highly competitive and rapidly evolving market, and we expect competition among companies in our market to continue to increase. Our ability to compete and succeed in this environment is directly correlated to our ability to recruit, incentivize and retain talented individuals in the areas of product development, sales, marketing, services and general and administrative functions. The market for skilled personnel in these areas is very competitive. Additionally, as we are headquartered in San Jose, CA, we face intense competition among large and small firms in the Silicon Valley market. Our compensation philosophy is designed to establish and maintain a compensation program that attracts and rewards talented individuals who possess the skills necessary to support our near-term objectives, create long-term value for our stockholders, expand our business and assist in the achievement of our strategic goals.

Table of Contents
Objectives

We have designed our executive compensation program to reward our executive officers, including our named executive officers, at a level consistent with our overall strategic and financial performance and to provide remuneration sufficient to attract, retain and motivate them to exert their best efforts in the highly competitive environment in which we operate. We believe in providing competitive compensation packages consisting of a combination of base salaries, annual cash bonuses and long-term incentive opportunities in the form of equity awards that are earned over a multi-year period. We believe the approach that has been adopted by our Compensation Committee, with an emphasis on variable cash compensation and equity awards, enables us to attract top talent, motivate successful short-term and long-term performance, satisfy our retention objectives and align the compensation of our executive officers with our performance and long-term value creation for our stockholders.

In 2021, the Compensation Committee reviewed our executive compensation program to ensure that it effectively supports our business strategies and is aligned with executive compensation best practices, and market trends and drives the success of our business.

Key Features of our Executive Compensation Program

The Compensation Committee reviews on an ongoing basis our executive compensation and benefits programs to evaluate whether these programs support our compensation philosophy and objectives, as described herein, and serve the interests of our stockholders. Our practices include the following, each of which the Compensation Committee believes reinforces our executive compensation philosophy and objectives:

WHAT WE DOWHAT WE DO NOT DO
Pay for Performance: We link pay to performance and stockholder interests by heavily weighting total compensation to long-term equity awards, a significant portion of which is performance-based, that align executive interests with our stockholders and encourage retention.No Single Trigger Acceleration: We do not provide for single trigger acceleration of equity awards following a change of control.
Linkage Between Bonus and Performance Measures: Our cash bonus program allows our executives to earn a target cash bonus only if specified performance metrics are met.No Guaranteed Bonuses; Bonus Payout Caps: We do not provide guaranteed minimum bonus amounts, and maximum payout levels apply to all amounts payable under the executive bonus plans.
Independent Compensation Advisor: The Compensation Committee selects and engages its own independent advisors.No Special Perquisites: We do not provide special perquisites for executives.
Thoughtful Peer Group Analysis: The Compensation Committee reviews external market data when making compensation decisions and annually reviews our peer groups with its independent compensation consultant.No Hedging in Company Securities: Executives, directors and all employees are prohibited from engaging in any hedging transaction with respect to company equity securities.
Thorough Compensation Risk Assessment: The Compensation Committee conducts an annual assessment of our executive and broad-based compensation programs to ensure prudent risk management.No Discounted Options / SARs or Option Repricing: We do not provide discounted stock options or stock appreciation rights, and we do not reprice underwater stock options without stockholder approval.
Compensation Committee Independence and Experience: The Compensation Committee is comprised solely of independent directors who have extensive experience.No Tax Gross-Ups: We do not provide tax gross-ups for “excess parachute payments.”
103

Table of Contents
Stock Ownership Guidelines: Our non-executive directors are subject to stock ownership guidelines equal to a value of not less than five times the then annual cash retainer for general board service, and our Chief Executive Officer is subject to stock ownership guidelines equal to a value of not less than six times his then annual base salary.No Service-Based Defined Benefit Pension Plan or Other Similar Benefits: We do not maintain a pension plan or provide other similar benefits.
Recoupment Policy: We maintain a clawback provision that provides our Board with the authority to recoup past incentive compensation (both cash and equity) paid to an executive officer in the event of a material restatement of our company’s financial results due to fraud or intentional misconduct of that executive officer.

Design

Our executive compensation program has been, and continues to be, heavily weighted towards equity. The Compensation Committee believes that compensation in the form of equity helps to align the interests of our executive officers with the long-term interests of our stockholders by driving achievement of our strategic and financial goals. We use restricted stock units, (or RSUs), and performance-based restricted stock units, or PSUs as our primary equity vehicles for our executive officers, including our named executive officers. We believe that RSUs align the interests of executive officers with stockholders and provide a longer-term focus through a multi-year vesting schedule, while managing dilution to existing investors and providing a level of predictability to our executive officers in the value of their compensation. Additionally, we believe that PSUs motivate and reward our executive officers for effectively executing long-term strategic, financial and operational objectives. The mix of PSUs (which directly link our executive officers’ target total direct compensation to the performance of our stock price) and RSUs (which offer more predictable value over time) further aligns the long-term interests of our executive officers with stockholders while addressing our retention objectives. On an annual basis, our Compensation Committee has reviewed, and will continue to review and evaluate, the types of equity vehicles best aligned with our business needs and priorities. To maintain a competitive compensation program, we also offer cash compensation in the form of base salaries and semi-annual cash bonuses tied to specific performance measures. We do not specifically target or benchmark our cash or equity compensation to align with those of our peer companies, but instead use the peer group information for general guidance. Further, when making compensation decisions for our executive officers, including our named executive officers, the Compensation Committee seeks to set both individual pay elements and target total direct compensation at competitive levels, using a balanced and flexible approach that is not restricted by adherence to specific percentile-based target levels. In other words, while competitive market data is an important reference in understanding general market practice, our actual compensation decisions reflect the Compensation Committee’s exercise of its business judgment after considering the following key factors:

to the extent there are gaps to market in target pay positioning for cash compensation, alignment may occur over multiple years;
the number of equity awards we grant will be subject to adjustment year-over-year to reflect dilution considerations, our retention objectives, company and individual performance, and other relevant factors; and
actual pay opportunities and outcomes will vary among executive officers and relative to market based on company performance and our position relative to our peers based on financial and other relevant criteria.

During 2021, our Compensation Committee, with the assistance of its compensation consultant, Compensia, Inc., or Compensia, reviewed our executive compensation program, including base salaries, bonuses, equity awards, and benefit programs, to ensure that our compensation program promotes stockholder interests and provides appropriate rewards and incentives for our executive officers.

Our Compensation-Setting Process

Oversight of Executive Compensation

Pursuant to its charter and in accordance with New York Stock Exchange rules, the Compensation Committee is responsible for reviewing, evaluating and approving the compensation arrangements of our executive officers and for establishing, benchmarking and maintaining our executive compensation policies and practices. Our Compensation Committee seeks input and receives recommendations from other members of our executive team when discussing the performance and compensation of other executive officers, and in determining the financial and accounting implications of our compensation programs and hiring decisions. The Compensation Committee is authorized to engage its own independent advisors to provide advice on matters related to executive compensation and general compensation programs. Currently, our Compensation Committee is
104

Table of Contents
comprised solely of independent directors. For additional information on the Compensation Committee, see “Committees of Our Board of Directors — Compensation Committee” elsewhere in this Form 10-K.

The initial compensation arrangements with our named executive officers were the result of arm’s-length negotiations between us and each individual executive officer at the time of his or her hire or appointment. In 2021, the Compensation Committee considered numerous factors in determining whether to make adjustments to the cash and equity compensation of our executive officers, including our named executive officers. The Compensation Committee reviewed the performance of the company and our executive officers, taking into consideration financial, operational, customer, strategic, product and competitive factors, as well as the succession planning objectives for our various executive officer positions. The Compensation Committee also reviewed a study by Compensia regarding the compensation of executives at companies in our compensation peer group to provide context and general guidance. However, as noted above, we do not target or benchmark the compensation levels of our executive officers to align with any specific percentile relative to our peer companies. Except with respect to his own compensation, our Chief Executive Officer made recommendations to the Compensation Committee regarding the compensation for our executive officers, which was also taken into account by the Compensation Committee in making its decisions regarding executive compensation. Our Chief Executive Officer was not present for the discussions of our Compensation Committee regarding his performance and compensation. The Compensation Committee also took into consideration the input from our Proxy Statementstockholders, both from our recent say on pay vote as well as stockholder outreach conducted in 2020 and 2021. Following deliberation, the Compensation Committee approved the cash compensation to be filedpaid to our named executive officers and as well as RSU and PSU awards for our named executive officers, each as described below and in the Summary Compensation Table.

Role of Human Resources Team

The role of our Human Resources team and management is to design our executive compensation programs, policies and governance and make recommendations to the Compensation Committee regarding these matters. Management is responsible for, among other things:

Reviewing the effectiveness of our compensation programs, including competitiveness and alignment with our objectives;
Recommending changes to compensation programs, as may be required, to ensure achievement of all program objectives;
Recommending base salaries, bonuses and other awards for our executive officers, including our named executive officers other than the Chief Executive Officer; and
Reviewing and making recommendations with respect to the adoption and approval of, or amendments to, company-wide incentive compensation plans.

Role of the Compensation Consultant

The Compensation Committee retained Compensia, Inc., an outside compensation expert, to advise on our 2021 executive compensation programs and practices and our executive compensation decisions given Compensia’s expertise in the technology industry and its knowledge of our peer companies. During 2021, Compensia provided the following services as requested by the Compensation Committee:

Assisted in the development of the compensation peer groups we used to understand market competitive compensation practices;
Reviewed and assessed our compensation practices and the cash and equity compensation levels of our executive officers (including an equity retention analysis), including our named executive officers;
Reviewed and assessed our current compensation programs to determine any changes that may need to be implemented in order to remain competitive with the market;
Provided market data and analysis regarding equity incentive plan dilution metrics and practices; and
Advised on regulatory developments relating to executive compensation.

All other analyses related to executive compensation for 2021 were conducted internally. Internal analyses included gathering and analyzing data, conducting a risk assessment relating to employee compensation and reviewing and advising on principal aspects of executive compensation. Base salaries, bonuses and equity awards for our executive officers were among the items reviewed based on market data provided by Compensia.

During 2021, the Compensation Committee reviewed the fees provided to Compensia relative to Compensia’s revenues, the services provided by Compensia to the Compensation Committee, the relationships between Compensia and its consultants and our executive officers, and other factors relating to Compensia’s independence, and concluded that Compensia is independent within the meaning of the listing standards of The New York Stock Exchange and that its engagement did not present any conflict of interest.

Compensation Peer Group

The Compensation Committee analyzes competitive market data on executive compensation levels and practices. This data is drawn from a select group of peer companies, as well as compensation survey data.

The Compensation Committee, with the assistance of Compensia, developed a group of peer companies, as detailed below, to be used as a reference for market positioning and for assessing competitive market compensation practices. In developing this peer group, consideration was given to our industry sector, geographies of the locations where our executives are based, company size (based on revenues and market capitalization) relative to our size and growth rate, and the comparability of business model and focus.

Following this review, Compensia recommended and the Compensation Committee approved use of a peer group of 20 publicly-traded companies for reference in making determinations regarding 2021 compensation:

8x8 Inc.LivePerson Inc.
A10 Networks, Inc.Model N, Inc.
Accolade*Omnicell, Inc.
Brightcove Inc.PagerDuty, Inc.*
Computer Programs and Systems, Inc.Phreesia Inc.
Domo, Inc.Rapid7, Inc.
Evolent Health, Inc.Tabula Rasa HealthCare
Health Catalyst, Inc.Workiva Inc.
HealthStream, Inc.Upland Software, Inc.
Inseego Corp.Zuora, Inc.*
______________________
*Added to the compensation peer group for 2021.

At the time of the compensation review, these companies had revenues for the most recently completed four quarters ranging from approximately $149 million to $1,022 million, and market capitalizations ranging from approximately $442 million to $5,874 million.

In addition, we removed the following companies from our 2021 peer group as they did not meet one or more of the criteria discussed above or were otherwise not considered to be a good fit based on geography or business: MobileIron, Inc., Livongo Health, Inc. and TeleNav, Inc.

This peer group was used by the Compensation Committee in connection with its annual review of our 2018 executive compensation program during 2021. Specifically, the Compensation Committee reviewed the compensation data drawn from the compensation peer group, in combination with industry-specific compensation survey data, to develop an objective, independent representation of the “competitive market” with respect to current executive compensation levels and related policies and practices. The Compensation Committee then evaluated how our pay practices and the compensation levels of our executive officers compared to the competitive market.

Elements of Our Executive Compensation Program

The key elements of our executive compensation program include base salary, semi-annual cash bonuses, equity-based awards, and health and welfare programs. Except with respect to target semi-annual cash bonuses, which typically are expressed as a pre-determined percentage of each executive officer’s base salary, we do not use specific formulas or weightings in determining the allocation of the various pay elements. Rather, each executive officer’s compensation has been designed to provide a combination of pay elements that are tied to achievement of our short-term and long-term financial and operational objectives. In particular, our use of RSU awards, which vest over three years, and PSU awards, which vest based on our total stockholder return (or TSR) relative to the S&P 600 Health Care Equipment and Services Index (or the Index) over three performance periods spanning a three-year period, promotes a culture of long-term value creation, while cash bonuses are payable semi-annually, promoting more immediate corporate performance.

In 2021, the Compensation Committee conducted its regular annual review of our executive compensation program, including an evaluation of competitive market practices; conducted annual performance reviews for our executive officers; considered adjustments to our executive officers’ base salaries and target annual bonus opportunities as needed; and made annual equity awards after taking account of any then currently unvested equity held by executive officers. Following deliberation and
106

Table of Contents
consideration of the factors discussed below, our Board of Directors and Compensation Committee determined that equity awards should continue to be a significant portion of executive compensation, and that it was in the best interests of the company and our stockholders to continue to use PSUs, which were introduced during 2020, and that cash compensation (including base salary and bonuses) should remain consistent with market norms at or above the 50th percentile.

Base Salary

We offer base salaries that are intended to provide a stable level of fixed compensation to our executive officers, including our named executive officers, for performance of their day-to-day responsibilities. Each named executive officer’s initial base salary was established as the result of arm’s-length negotiation with the individual at the time of his or her hiring or appointment. Base salaries for our executive officers are reviewed annually to determine whether an adjustment is warranted or required, taking into account the responsibilities required by the executive’s position, the executive’s length of service in a position and at our company, and the amount of other elements of compensation. The amount of any increase or decrease in base salary is considered based on the above-mentioned factors, as well as the company’s financial performance and, in the discretion of the Compensation Committee, the compensation paid by our competitors and/or other comparable-sized companies.

For 2021, the Compensation Committee reviewed the base salaries of our named executive officers, after considering a compensation analysis performed by Compensia. The base salaries paid to our named executive officers for 2021 are set forth in the Summary Compensation Table below.

Annual MeetingCash Bonuses

In addition to the payment of Stockholders.salaries that it believes are competitive and assist in the retention of our executive officers, our Compensation Committee believes that a significant portion of our executive officers’ cash compensation should be tied to corporate performance. Our cash bonus program, payments under which are included as “Non-Equity Incentive Plan Compensation” in the Summary Compensation Table below, allows our executives to earn a target cash bonus if specified metrics are satisfied at the target level, to earn a reduced level of bonus if the metrics achieved are below the target level but above a specified threshold level, and to receive a larger bonus if metrics are achieved at a level above the target. The target bonus is set as a percentage of each officer’s base salary:

For 2021, the payment of cash bonuses was based on the achievement of a revenue target, with the bonus calculation being further conditioned on achievement of an adjusted EBITDA threshold. This structure is based on our Compensation Committee’s decision that the most important factor in increasing stockholder value in 2021 was revenue growth. The Compensation Committee further determined that the inclusion of an earnings metric, such as the adjusted EBITDA threshold, would help to ensure that revenue growth was sought in a fiscally prudent manner. These revenue and adjusted EBITDA measures are provided below and were established by the Compensation Committee based on the corresponding amounts in the annual financial plan approved by the Board of Directors. Executives were eligible to receive the bonuses in two payments, based on company performance against the targets in the first and second half of the year. Additionally, the cash bonus amounts for each half of the year are zero if the actual revenue or adjusted EBITDA falls below specified thresholds.

Table of Contents
For 2021, the Compensation Committee determined that 100% of the metrics were achieved, and awarded the cash bonuses set forth in the Summary Compensation Table below.

Mr. Johnson is also compensated through a performance-based sales commission plan. Under that plan, his 2021 target commission was $127.0 thousand and his actual commission was $133.2 thousand.

Ms. Duffy is also compensated through a performance-based sales commission plan. Under that plan, her 2021 target commission was $102.0 thousand and her actual commission was $102.2 thousand.

Equity-Based Awards

The majority of the target total direct compensation of our executive officers, including our named executive officers, is provided through equity awards. By having a significant percentage of our executive officers’ target total direct compensation payable in the form of equity that vests over a number of years and, thus, subject to higher risk and longer vesting than cash compensation, our executive officers are motivated to focus on long-term performance. This approach also helps retain key employees because the RSUs are subject to a vesting period, and unvested awards are forfeited by the employee when employment ends. We received feedback from some of our stockholders indicating a preference for performance-based equity awards. Our Compensation Committee considered this feedback, and determined that a mix of time-based equity awards and performance-based equity awards best aligned with the interests of our stockholders by creating an appropriate balance between our goals of business execution, long-term share price growth and named executive officer retention. Accordingly, our Compensation Committee introduced PSUs in 2020 and continued to grant PSUs in 2021. Our PSUs are measured based on our three-year relative total shareholder return.

In granting PSUs, the Compensation Committee considered a variety of factors, including, our continued growth, the dynamic, highly competitive and fast-moving healthcare technology industry, and the difficulty of predicting future performance in such an environment. As a result, the Compensation Committee concluded that relative total shareholder return (TSR) over a three-year performance period, which is in line with peer practice in our industry, best-enabled the company to incentivize high-caliber executives over a longer-term horizon and align their success with that of our stockholders. Our Compensation Committee sought to establish performance goals that were sufficiently rigorous to align with stockholder interests, but also sufficiently reasonable to retain incentive value for our executives. Accordingly, our Compensation Committee determined that the PSU could be earned at target TSR performance that matches the Index, with lower or higher potential payments than target based on actual TSR achievement. We believe the selected structure and terms of the PSUs best motivate the named executive officers to perform against reasonably aggressive targets in alignment with our stockholders and rewards our leadership team for taking actions today that will create value for our stakeholders for years to come.

We make annual equity grants to our executive officers in order to align their interests with those of our stockholders and to ensure appropriate incentives are in place to promote a focus on our long-term strategic and financial objectives. The sizes of these awards were not determined based on a specific formula, but rather through the exercise of the collective judgment of the Compensation Committee and after considering the following factors:

each executive officer’s individual performance, including financial, operational, customer, strategic, product and competitive factors;
the appropriate level of compensation for the position;
the need to hire or retain an individual in a particular position and the perceived retentive value of the proposed awards;
the size and vesting schedule of outstanding and unvested equity awards;
the level of each executive officer’s target total cash compensation (base salary plus target annual cash bonus opportunity); and
the recommendations of the Chief Executive Officer (except with respect to his award).

For the Chief Executive Officer, executive leadership factors were also considered. In addition, the Compensation Committee reviews and considers the equity awards granted to the executives at the companies in the compensation peer groups, although it does not specifically target or benchmark to those companies.

Our Compensation Committee typically grants awards in June of each year, and calculates the number of shares subject to the awards using the average closing stock price over the month prior to the date of grant. Our Compensation Committee granted these awards in July because it was necessary to wait until after our shareholders approved our new 2021 Equity Incentive Plan.

Topic 718. The grant date fair value of the PSUs computed in accordance with FASB ASC Topic 718 is set forth in the Summary Compensation Table below.
(3) Mr. Spencer left the company in June 2021.

On July 1, 2021, the Compensation Committee granted PSUs based on our total stockholder return percentile rank (or TSR Percentile Rank) within the range of the percentile distribution of the total stockholder returns of the companies included in the Index over the following three performance periods (or Performance Periods): (i) the single year beginning July 1, 2021 and ending June 30, 2022 (ii) the two approximate years beginning July 1, 2021 and ending May 31, 2023 and (iii) the three approximate years beginning July 1, 2021 and ending May 31, 2024. The Compensation Committee, in consultation with Compensia, believed that the Index was an appropriate comparison because it represents a broad group of companies with whom we compete for talent and investment dollars and is broad enough to account for potential consolidation in our industry sector. Also, the PSUs reward and incentivize continued performance over each period within a three-year period.

At the end of each Performance Period, the Compensation Committee will compare our TSR Percentile Rank based on the percentage change in our share price against the range of the percentile distribution of the changes in the share price of the companies in the Index, in each case using the difference between the average of the daily closing prices per share during the 30 trading days ending immediately prior to the grant date and the applicable performance period (or the TSR). The number of PSUs earned in a particular Performance Period is then determined by multiplying the number of PSUs eligible to be earned during the applicable Performance Period, by the performance multiplier corresponding to our TSR percentile rank as set forth in the table below:

Item 14.50th percentilePrincipal Accounting Fees and Services100%
75th percentile or greater200%

If our TSR Percentile Rank is the 50th percentile, then 100% of the PSUs eligible to be earned during the applicable Performance Period will vest. The maximum number of PSUs that may be earned and vest during an applicable Performance Period is 200%, subject to our achievement of a TSR percentile rank of 75th or greater. As noted above, our Compensation Committee wanted to balance the need for rigorous performance goals to align with stockholder interests, but also have goals that were sufficiently reasonable to maintain the incentive value for our executives. Accordingly, our Compensation Committee determined that PSUs would be earned at target for achievement matching the Index, but the PSUs earned could increase or decrease, as noted above, based on the Company’s TSR achievement relative to the Index.

The number of PSUs earned during each of the first and second Performance Periods may not exceed one-third of the target number of PSUs subject to the PSU award. The number of PSUs earned during the third Performance period may not exceed the maximum number of PSUs subject to the PSU award and will be reduced by the number of PSUs earned during the first and second Performance Periods. Performance multipliers between the TSR Percentile Ranks set forth in the table above will be determined based on linear interpolation. In addition, if our TSR at the end of the third performance period is negative, the total number of shares earned for the third performance period may not exceed the target number of shares subject to the PSU.

PSUs will vest upon certification by the Compensation Committee of the TSR Percentile Rank attained for an applicable Performance Period. Each named executive officer must remain employed by us on the last day of each applicable Performance Period in order to earn and vest in the PSUs eligible to be earned during such Performance Period, except as discussed below in “Employment, Severance and Change of Control Agreements.”

The Compensation Committee reviewed the size and vesting schedule for the remaining unvested portion of all outstanding equity awards held by our executive officers, including our named executive officers, and agreed that the existing equity awards, together with the existing equity grants, appropriately satisfied our motivation and retention goals for each individual.

2020 PSU Achievement

In June 2020, our Compensation Committee granted to certain of our executive officers PSUs (or 2020 PSUs). These 2020 PSUs vest based on our TSR Percentile Rank within the range of the percentile distribution of the total stockholder returns of the component companies in the S&P 600 Health Care Equipment and Services Index over the following three performance periods: (i) the single year beginning June 1, 2020 and ending May 31, 2021, (ii) the two years beginning June 1, 2020 and ending May 31, 2022 and (iii) the three years beginning June 1, 2020 and ending May 31, 2023. Based on our TSR percentile rank of 64th percentile as of May 31, 2021, the final date of the first performance period, one third of the 2020 PSUs were

earned and became vested at such time. For additional detail regarding the 2020 PSUs, please see page 47 of our definitive proxy statement filed with the Securities and Exchange Commission on April 15, 2021.

Treatment in Connection with the Merger

Treatment of Vocera Equity Awards

As of immediately prior to the closing of the Merger, each RSU and PSU (after giving effect to the PSU Achievement Calculation (as defined below)) that is outstanding and unvested will not be assumed by Stryker, and as a result under the terms of the applicable Vocera equity incentive plan and the Merger Agreement, will become immediately vested in full. At the closing of the Merger (after giving effect to such accelerated vesting), each such vested RSU and PSU will be canceled and the holder thereof will be entitled to receive an amount in cash, without interest, less any applicable tax withholding, equal to the number of Shares issuable under such RSU or PSU multiplied by the merger consideration (collectively, the “RSU Cash Consideration”).

The achievement of applicable performance metrics of each PSU (or portion thereof) that is outstanding and unvested for which the performance period has not been completed as of the closing of the Merger will, as of immediately prior to the closing of the Merger, be determined in good faith by our Board or a committee thereof in accordance with the terms of the PSU award agreements by multiplying the target number of shares subject to the PSU by the applicable multiplier based on actual performance measured from the grant date of the applicable PSU through the last trading day immediately preceding the day the Merger closing occurs and using the merger consideration as our share price with respect to the performance goals, which are based on total shareholder return. The resulting number of shares subject to each PSU will be reduced by the number of shares, if any, earned and paid with respect to any previously completed performance periods applicable to such PSU. However, for any performance period that has been completed prior to the closing of the Merger, but for which the performance achievement has not yet been determined as of prior to the closing of the Merger, the our Board or a committee thereof will determine in good faith the performance achievement and the resulting number of shares eligible to vest on the applicable vesting date prior the closing of the Merger based on actual performance of the applicable performance goals as set forth under the applicable award agreement. Based on the merger consideration, the applicable performance metrics for all outstanding PSUs are expected to be achieved at the maximum level and the maximum number of Shares subject to each PSU is expected to be eligible to vest as of immediately prior to the closing of the Merger.

As of immediately prior to the closing of the Merger, each stock option that is outstanding (other than rights under the ESPP) will not be assumed by Stryker, and as a result under the terms of the applicable Vocera equity incentive plan and the Merger Agreement, will be cancelled and the holder thereof will be entitled to receive an amount of cash, without interest, less any applicable tax withholding, equal to the product obtained by multiplying i) the excess (if any) of the merger consideration over the exercise price per share of company common stock underlying such company stock option by (ii) the number of shares of company common stock underlying such outstanding stock options (the “Stock Option Cash Consideration”).

Stryker will cause the surviving corporation to pay the RSU Cash Consideration and the Stock Option Cash Consideration at or reasonably promptly (generally no later than 5 business days) after the closing of the Merger, in accordance with the terms of the Merger Agreement.

In accordance with the Merger Agreement, immediately prior to the closing of the Merger, the ESPP will terminate and any in-progress ESPP offering period will be shortened and the applicable purchase date will occur before the closing of the Merger. All shares purchased under the ESPP will be treated identically to other outstanding shares, such that they will be canceled and converted into the right to receive the merger consideration.

Benefits Programs

Our employee benefit programs, including our 401(k) plan, ESPP, and health and welfare programs, including health savings accounts and flexible spending arrangements, are designed to provide a competitive level of benefits to our employees generally, including our executive officers and their families. We adjust our employee benefit programs as needed based upon regular monitoring of applicable laws and practices and the competitive market. Our executive officers are eligible to participate in the same employee benefit plans and programs, and on the same terms and conditions, as all other U.S. full-time employees.

Perquisites and Other Personal Benefits

Currently, we do not view perquisites or other personal benefits as a significant component of our executive compensation program. Accordingly, we do not generally provide perquisites to our executive team.

Post-Employment Compensation
111

Table of Contents

Certain of our executive officers have post-employment compensation arrangements, which provide for severance payments and benefits in the event of a termination of employment under certain conditions, including following a change of control of the company. The Compensation Committee determined that these arrangements were both competitively reasonable and necessary to recruit and retain key executives. The material terms of these post-employment payments to named executive officers are set forth in “Employment, Severance and Change of Control Agreements” below. These agreements do not provide for single trigger equity acceleration following a change of control and do not provide tax gross-ups for “excess parachute payments.”

Other Compensation Policies and Practices

Executive Officer Recoupment Policy

We maintain a clawback provision that provides our Board with the authority to recoup past incentive compensation from an executive officer in the event of a material restatement of our company’s financial results due to fraud or intentional misconduct of that executive officer.

Equity Administration Committee

Our Compensation Committee provides that the Equity Administration Committee, consisting of the Chief Executive Officer, the Chief Financial Officer and the General Counsel, may make equity awards to non-executive employees within prescribed limits. Generally, equity awards will be effective on the 1st market day of the month following approval by the Equity Administration Committee, unless determined otherwise with advice of counsel. While we do not generally grant stock options at this time, the exercise price of all stock options must be equal to or greater than the fair market value of our common stock on the date of grant.

Derivatives Trading and Anti-Hedging Policy

Our Policy Prohibiting Insider Trading prohibits our employees, including our executive officers and members of our Board of Directors, from purchasing financial instruments, or otherwise engaging in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market value of company common stock, such as prepaid variable forward contracts, equity swaps, collars, forward sale contracts and exchange funds.

Stock Ownership Guidelines

We maintain stock ownership guidelines that require our Chief Executive Officer, as well as our non-executive directors, to maintain a specified level of stock ownership.

Compensation Policies and Practices as they relate to Risk Management

The Compensation Committee has reviewed our executive and employee compensation programs and does not believe that our compensation policies and practices encourage undue or inappropriate risk taking or create risks that are reasonably likely to have a material adverse effect on us. The reasons for the Compensation Committee’s determination include the following:

We structure our compensation program to consist of both fixed and variable components. The fixed (or base salary) component of our compensation programs is designed to provide income independent of our stock price performance so that employees will not focus exclusively on stock price performance to the detriment of other important business metrics. The variable (cash bonus and equity) components of our compensation programs are designed to reward both short-term and long-term company performance, which we believe discourages employees from taking actions that focus only on our short-term success and helps align our employees with our stockholders and on our longer-term success. Our RSUs have time-based vesting and our PSUs have a multi-year performance period encouraging long-term, sustained success.
We maintain internal controls over the measurement and calculation of financial information, which are designed to prevent this information from being manipulated by any employee, including our executive officers.
While we generally do not cap the cash incentive award for our Sales Compensation Plan to maximize the incentive for our sales force to meet and exceed their revenue objectives, we do maintain internal controls over the determination of sales incentive awards which we believe help prevent problematic behaviors.
Our employees are required to comply with our Employee Code of Conduct and Ethics, which covers, among other things, accuracy in keeping financial and business records.
The Compensation Committee approves the employee annual and new hire equity award guidelines as well as the overall annual equity pool. Any recommended equity awards outside these guidelines require approval by the Compensation Committee. We believe that this helps ensure we grant equity compensation appropriately and in a sustainable manner.

A significant portion of the compensation paid to our executive officers and the members of our Board of Directors is in the form of RSUs and, for this Item is incorporated by referenceour executive officers, PSUs to align their interests with the interests of stockholders.
We maintain Stock Ownership Guidelines for our Chief Executive Officer and the members of the Board of Directors to ensure that they retain specified levels of equity in the company.
As part of our Policy Prohibiting Insider Trading, we prohibit the trading of derivatives or hedging transactions involving our securities so that our executive officers and other employees cannot insulate themselves from the effects of poor stock price performance.

Tax and Accounting Considerations

Deductibility of Executive Compensation

Section 162(m) of the Code limits the amount that we may deduct from our Proxy Statementfederal income taxes for remuneration paid to our named executive officers (other than our Chief Financial Officer) to $1 million dollars per executive officer per year. “Grandfather” provisions of the Code provide exceptions from this deduction limitation and may apply to certain compensation arrangements, including certain grants of stock options and certain RSUs, that were entered into before the company was publicly traded and through November 2, 2017. Except for compensation attributable to the exercise of most options granted prior to November 2, 2017 under the “grandfather provisions,” compensation in excess of $1 million will likely not be deductible.

No Tax Reimbursement of Parachute Payments and Deferred Compensation

We did not provide any executive officer, including any named executive officer, with a “gross-up” or other reimbursement payment for any tax liability that he or she might owe as a result of the application of Sections 280G, 4999, or 409A of the Code during 2021, and we have not agreed and are not otherwise obligated to provide any named executive officer with such a “gross-up” or other reimbursement.

Accounting Treatment

We account for stock compensation in accordance with the authoritative guidance set forth in FASB ASC Topic 718, which requires companies to measure and recognize the compensation expense for all share-based awards made to employees and directors over the period during which the award recipient is required to perform services in exchange for the award. We determine both the grant date fair value and the service period based on applicable accounting standards. This calculation is performed for accounting purposes and reported in the compensation tables included in this Form 10-K.

Report of the Compensation Committee

The Compensation Committee has reviewed and discussed the Compensation Discussion and Analysis included in this Form 10-K with management and, based on such review and discussions, the Compensation Committee recommended to our Board of Directors that the Compensation Discussion and Analysis be incorporated in this Form 10-K for fiscal year 2021.

(1) Represents RSUs granted under our 2012 and 2021 Equity Incentive Plan which vests in three equal installments commencing on the first anniversary of the first day of the month following the award grant date.
(2) The market value of the shares of RSUs that have not vested is calculated by multiplying the number of unvested shares held by the applicable named executive officer by the closing price of our common stock on December 31, 2021, the last trading day of our fiscal year, which was $64.84.
(3) PSUs with a grant date of June 1, 2020 (or 2020 PSUs) vest based on our total stockholder return percentile rank (or “TSR Percentile Rank”) within the range of the percentile distribution of the total stockholder returns of the component companies in the S&P 600 Health Care Equipment and Services Index over the following three performance periods: (i) the single year beginning June 1, 2020 and ending May 31, 2021, (ii) the two years beginning June 1, 2020 and ending May 31, 2022 and (iii) the three years beginning June 1, 2020 and ending May 31, 2023. Based on our 64th TSR percentile as of May 31, 2021, the final date of the first performance period, one third of the 2020 PSUs were earned and became vested at such time. The outstanding 2020 PSUs represent the remaining target number of shares subject to the PSU that may be earned.
(4) PSUs with a grant date of July 1, 2021 (or 2021 PSUs) vest based on our total stockholder return percentile rank (or TSR Percentile Rank) within the range of the percentile distribution of the total stockholder returns of the companies included in the S&P 600 Health Care Equipment and Services Index over the following three performance periods: (i) the single year beginning July 1, 2021 and ending June 30, 2022, (ii) the two approximate years beginning July 1, 2021 and ending May 31, 2023 and (iii) the three approximate years beginning July 1, 2020 and ending May 31, 2024. The unvested 2021 PSUs in the table above include the target number of 2021 PSUs. If the PSUs metrics were achieved at maximum, the executive (if applicable) would be eligible to receive the maximum number of 2021 PSUs included in the “Grant of Plan-Based Awards” table above.
(5) The market value of the PSUs that have not vested is calculated by multiplying the number of unvested shares held by the applicable named executive officer by the closing price of our common stock on December 31, 2021, the last trading day of our fiscal year, which was $64.84.

(6) Except as otherwise described in these footnotes, all options vest as to 1/4th of the shares of common stock underlying the options on the first anniversary of the vesting commencement date and as to 1/48th of the shares of common stock underlying the option each month thereafter.
(7) The exercise price of our equity awards granted after March 28, 2012 is the closing price of our common stock on the date of grant.

(1)The value realized on exercise is calculated as the difference between the market price of our common stock at the time of exercise on the exercise date and the applicable exercise price of those options.
(2)The value realized on vesting is calculated by multiplying the number of shares vesting by the closing price of our common stock as traded on the NYSE on the applicable vesting date or, if the vesting date was not a trading day, the next trading date.

CEO Pay Ratio

The 2021 annual total compensation of our Chief Executive Officer was $8,072,541, the 2021 annual total compensation of our median compensated employee was $187,093 and the ratio of these amounts is 43.1 to 1.

In 2021, there was no change in our employee population or employee compensation arrangements that we believe would significantly impact the pay ratio. Accordingly, for purposes of calculating the pay ratio set forth above, we are permitted to use the same median employee that we identified for purposes of our 2020 pay ratio. For a description of our methodology for identifying the median employee, see “CEO Pay Ratio” on page 48 of our definitive proxy statement filed with the Securities and Exchange Commission on April 16, 2020.

Because SEC rules for identifying the median of the annual total compensation of all employees allow companies to adopt a variety of methodologies, apply certain exclusions, and make reasonable estimates and assumptions that reflect their employee population and compensation practices, the pay ratio reported by other companies may not be comparable to our pay ratio, as other companies have different employee populations and compensation practices and may have used different methodologies, exclusions, estimates and assumptions in calculating their pay ratios. As explained by the SEC when it adopted these rules, the rule was not designed to facilitate comparisons of pay ratios among different companies, even companies within the same industry, but rather to allow stockholders to better understand and assess each particular company’s compensation practices and pay ratio disclosures.

Employment, Severance and Change of Control Agreements

Brent D. Lang. We entered into an offer letter agreement with Brent D. Lang, our President and Chief Executive Officer, dated June 8, 2012, which superseded an offer letter agreement, dated November 12, 2007. The offer letter agreement has no specific term and constitutes at-will employment.

In addition, in April 2013 our Compensation Committee authorized that we enter into a revised change of control severance agreement, in the form previously approved by our Board of Directors, with Mr. Lang to reflect his transition to our Chief Executive Officer in June 2013. Our Compensation Committee amended and restated this change of control severance agreement in September 2021 to make certain clarifications, but did not modify the benefits payable in connection with a termination of employment or a change of control of the company. The agreement with Mr. Lang provides that, in the event of
117

Table of Contents
Mr. Lang’s termination without cause or resignation for good reason, he will be entitled to receive cash severance payments equal to one year of his annual base salary, plus the greater of his target bonus for the year of termination or the amount of bonus paid to him in the prior year, plus 12 months of acceleration of outstanding equity awards and 12 months of COBRA coverage. For a termination without cause or resignation for good reason occurring within two months prior to, or 12 months following, a change of control of Vocera (the “Change of Control Period”), the agreement provides that Mr. Lang will be entitled to receive a cash severance payment equal to 150% of his annual base salary plus 150% of the greater of his target bonus for the year of termination or the amount of bonus paid to him in the prior year, plus acceleration of 100% of his outstanding equity awards in addition to 18 months of COBRA coverage.

In addition, Mr. Lang’s PSUs, granted in June 2020 and July 2021, the terms of which are described above in “Compensation Discussion and Analysis — Equity-Based Awards” provide that upon a termination of Mr. Lang’s employment with us for any reason other than a termination without cause or resignation for good reason prior to the end of an applicable Performance Period (as described above in “Compensation Discussion and Analysis — Equity-Based Awards”), all PSUs which have not been earned as of the date of such termination will be forfeited. In the event Mr. Lang’s employment with us terminates due to a termination without cause or resignation for good reason, in each case outside of the Change in Control Period (as defined in Mr. Lang’s change of control severance agreement and described above), Mr. Lang will remain eligible to vest in any PSUs that are earned as a result of the achievement of the performance metrics in respect of the Performance Period that ends within twelve months following the date of such termination as if he had remained employed with us on the date such Performance Period ended, subject to any reduction for prior earned tranches of the PSUs, if applicable (as described above in “Compensation Discussion and Analysis — Equity Based Awards”).

In the event of a “corporate transaction”, as defined in our 2012 Equity Incentive Plan or 2021 Equity Incentive Plan, as applicable, before the end of any of the Performance Periods, a CIC Performance Period (or the CIC Performance Period) beginning on the grant date of a PSU award and ending on the last trading day immediately preceding the closing date of the corporate transaction will be used for determining the number of earned PSUs, except that our TSR (as described above in “Compensation Discussion and Analysis — Equity-Based Awards”) for such period will be determined by using the price per share to be paid to stockholders in such corporate transaction. The PSUs earned during such period will be reduced by the number of PSUs previously earned during prior Performance Periods, as applicable. The number of PSUs earned in respect of the CIC Performance Period will be multiplied by a fraction, the numerator of which equals the number of days in the CIC Performance Period and the denominator of which equals the number of days contained in the third Performance Period, and such number of PSUs shall be settled within 30 days following the corporate transaction (or the Closing-Settled PSUs). The portion of PSUs earned during the CIC Performance Period that exceeds the number of Closing-Settled PSUs will convert to time-based vesting (or the Time-Vesting PSUs) and will vest in equal installments on the remaining original Performance Period end dates, subject to Mr. Lang’s employment on such dates. In the event that the PSUs are not assumed or replaced by the successor entity in connection with the corporate transaction, any PSUs that are earned upon the corporate transaction as described in this paragraph will become vested immediately prior to the corporate transaction. In the event of a termination without cause or resignation for good reason during the Change in Control Period, 100% of the Time-Vesting PSUs shall accelerate (the “Time-Vesting Acceleration Percentage”).

For additional information on the treatment of stock options, PSUs and RSUs in connection with the pending Merger, see the section titled “Treatment in Connection with the Merger” above.

In addition, we entered into a change of control severance agreement with Mr. Anheier in June 2021. Our Compensation Committee amended and restated this change of control severance agreement in September 2021 to make certain clarifications, but did not modify the benefits payable in connection with a termination of employment or a change of control of the company.

For a termination without cause or resignation for good reason occurring within a Change of Control Period, the agreement provides that Mr. Anheier will be entitled to receive a cash severance payment equal to 100% of his annual base salary plus 100% of the greater of his target bonus for the year of termination or the amount of bonus paid to him in the prior year, plus acceleration of 100% of his outstanding equity awards in addition to 12 months of COBRA coverage.

(1) The value of accelerated RSUs is calculated by multiplying the number of shares being accelerated by the closing price of our common stock on December 31, 2021, the last trading day of our fiscal year, which was $64.84. The value of accelerated PSUs is calculated as described above, using the closing price of our common stock on December 31, 2021, the last trading day of our fiscal year, which was $64.84.
(2) As of December 31, 2021, all options are fully vested, and the underlying shares are no longer subject to acceleration under change of control severance agreements.

The severance payments under the change of control severance agreements with each of our executive officers are contingent upon such executive officer’s execution, delivery and non-revocation of a release and waiver of claims satisfactory to us within 45 days of such executive officer’s separation from service.

For information on the treatment of stock options, PSUs and RSUs in connection with the pending Merger, see the section titled “Treatment in Connection with the Merger” above.Please also see page 13 of the Schedule 14D-9filed with the Securities and Exchange Commission on January 25, 2021 for a table quantifying amounts payable in connection with the Merger.

Mr. Spencer left the company in June 2021.He did not receive any termination benefits or payments and was not eligible for any as of December 31, 2021.

Restricted Covenant & Compensation Recovery Agreement

On February 8, 2022, Stryker and each of Brent D. Lang, our Chief Executive Officer, Paul T. Johnson, our Chief Commercial Officer, Douglas A. Carlen, our General Counsel, and Steven J. Anheier, our Chief Financial Officer (each, a “Restricted Executive”) entered into a Restrictive Covenant and Compensation Recovery Agreement (each a “Restrictive Covenant Agreement”). Each Restrictive Covenant Agreement requires that each Restricted Executive, for a period of three (3) years following the date upon which the Merger is consummated (the “Closing Date”): (i) not compete, directly or indirectly, with the Company’s business as it exists as of the Closing Date, (ii) not solicit certain employees and independent contractors of the Company and (iii) not solicit the business of certain current, prospective of past customers of the Company. Certain violations by a Restricted Executive of the applicable Restrictive Covenant Agreement may require such executive to repay to Stryker a designated amount of the consideration received by the Restricted Executive in connection with the Merger. The Restrictive Covenant Agreements are contingent upon and effective as of the consummation of the Merger. Other than the Restrictive Covenant Agreements, none of the Restricted Executives have entered into any other agreements with Stryker or any of its affiliates.

Director Compensation

We compensate our non-employee directors with a combination of cash and equity. The form and amount of compensation paid to our non-employee directors for serving on our Board and its committees is designed to be competitive in light of industry practices and the obligations imposed by such service. In order to align the long-term interests of our directors with those of our stockholders, a portion of the director compensation is provided in equity-based compensation. The value of total annualized compensation of our non-employee directors is targeted to be at approximately the median of a peer group of similarly-sized technology companies with similar business and financial characteristics. The director compensation practice of this peer group
120

Table of Contents
of companies was the benchmark used when considering the competitiveness of our director compensation. Our Compensation Committee’s independent compensation consultant, Compensia, previously collected and developed the competitive data and analyses that the Committee used to benchmark and establish our director compensation and based on advice from Compensia, the Compensation Committee determined that our non-employee director compensation is reasonable and appropriate, and the Board approved the director compensation as set forth below. The Compensation Committee periodically reviews market data in consultation with its independent advisor Compensia.

Annual Cash Retainer. Each director receives an annual base cash retainer of $40,000 for general board service, to be paid quarterly. Additionally, we compensate our Board of Directors for service on our committees and for service as our lead independent director and the chair of our Board as follows:

The chair of our Audit Committee receives an annual cash retainer of $20,000 for such service, paid quarterly, and each of the other members of the Audit Committee receives an annual cash retainer of $10,000, paid quarterly.
The chair of our Compensation Committee receives an annual cash retainer of $12,500 for such service, paid quarterly, and each of the other members of the Compensation Committee receives an annual cash retainer of $5,000, paid quarterly.
The chair of our Governance and Nominating Committee receives an annual cash retainer of $9,000 for such service, paid quarterly, and the other member of the Governance and Nominating Committee receives an annual cash retainer of $5,000, paid quarterly.
Our lead independent director receives an additional annual cash retainer of $20,000 for such service, paid quarterly.
The non-executive chair of our Board of Directors receives an additional annual cash retainer of $25,000 for such service, paid quarterly. Since our current chair, Mr. Lang, is an executive officer of the Company, he does not receive this cash retainer.

Equity Awards. In April 2021, the Board approved the annual equity grant to non-employee directors effective July 1, 2021 of a number of restricted stock units calculated as $150,000 divided by the average daily closing price of our common stock as reported by the New York Stock Exchange during May 2021 (rounded down to the nearest share). Each restricted stock unit (“RSU”) will vest in full on the earlier of (i) July 1, 2022 or (ii) the date of the 2022 annual meeting, subject to the director’s continuous service through such vesting date, and will automatically vest in full upon a change of control of our company. Equity awards for new non-employee directors shall be determined by the Compensation Committee. Notwithstanding the foregoing, no non-employee director shall receive equity awards, that when combined with cash compensation received for service as a non-employee director, with a fair market value on the date of grant that exceeds (i) $600,000 in value in the year of such director’s initial appointment to the Board or (ii) $400,000 in value in any other calendar year.

Other. We reimburse all of our directors for travel, director continuing education programs and other business expenses incurred in connection with their services as a member of our Board of Directors and its committees, and we extend coverage to them under our travel accident and directors’ and officers’ indemnification insurance policies.

The following table provides information for the year ended December 31, 2021 regarding all compensation awarded to, earned by or paid to each person who served as a non-employee director during 2021. Mr. Lang, our current Chairman and Chief Executive Officer, did not receive any compensation for his service as director during the year ended December 31, 2021.

Item 13.Certain Relationships and Related Transactions, and Director Independence

Related Party Transactions

From January 1, 2021 to the present, there have been no material transactions, and there are currently no proposed transactions, to which we or any of our subsidiaries was (or is to be) a party and in which any director, director nominee, executive officer, holder of more than 5% of our capital stock, or any immediate family member of or person sharing the household with any of these individuals, had (or will have) a direct or indirect material interest, except for payments set forth under “Executive Compensation” and “Director Compensation” above.

Review, approval or ratification of transactions with related parties

Our Board of Directors recognizes that transactions between our company and persons or entities that may be deemed related persons can present potential or actual conflicts of interest and create the appearance of impropriety. Accordingly, our Board has delegated authority for the review and approval of all related person transactions to the Governance and Nominating Committee of our Board of Directors. We have adopted a Related Person Transactions Policy to provide procedures for reviewing, approving and ratifying any transaction involving our company or any of its subsidiaries in which a 5% or greater stockholder, director, executive officer or members of their immediate family have or will have a material interest as determined by our Governance and Nominating Committee. This policy is intended to supplement, and not to supersede, our company’s other policies that may be applicable to or involve transactions with related persons. The full text of this policy is posted on the investor relations section of our website at www.vocera.com.

Director Independence

Our common stock is listed on the New York Stock Exchange. The listing rules of the New York Stock Exchange require that a majority of the members of our Board of Directors be independent. Our Board of Directors has confirmed that all of our directors and director nominees are independent, except Brent D. Lang. Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, our Board of Directors determined each of Michael Burkland, Julie Iskow, Howard E. Janzen, Alexa King, John N. McMullen, Sharon L. O’Keefe, Ronald A. Paulus and Bharat Sundaram does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors or director nominees is “independent” as that term is defined under the rules of the New York Stock Exchange and the Securities and Exchange Commission. In making this determination, our Board of Directors considered the relationships that each director has with our company and all other facts and circumstances our Board of Directors deemed relevant in determining their independence, including certain contracts for products or services in place between Vocera and entities affiliated with our directors. Each director who serves on our Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee are independent under the listing rules of the New York Stock Exchange. See “Corporate Governance” in Item 10 above for more information.

Presiding Director of Independent Director Meetings

The independent directors meet in regularly scheduled executive sessions without management over which our lead independent director presides. Our lead independent director is currently Mr. Janzen.

124

Table of Contents
Board and Committee Meetings and Attendance

The Board of Directors and its committees meet throughout the year on a pre-determined schedule and also hold special meetings and act by written consent from time to time.

Typically, in conjunction with the regularly scheduled meetings of the Board, the independent directors meet in executive sessions outside the presence of management.

These services may include audit services, audit-related services, tax services and other services. Pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget.
