Business.OverviewEverbridge is a global software company that provides enterprise software applications that automate and accelerate organizations’ operational response tocritical events in order to keep people safe and businesses running. During public safety threats such as active shooter situations, terrorist attacks or severeweather conditions, as well as critical business events such as IT outages, cyber-attacks or other incidents such as product recalls or supply-chaininterruptions, our SaaS-based platform enables our customers to quickly and reliably aggregate and assess threat data, locate people at risk and respondersable to assist, automate the execution of pre-defined communications processes, and track progress on executing response plans. Our customers use ourplatform to identify and assess hundreds of different types of threats to their organizations, people, assets or brand. Our solutions enable organizations todeliver intelligent, contextual messages to, and receive verification of delivery from, hundreds or millions of recipients, across multiple communicationsmodalities such as voice, SMS and e-mail. Our applications enable the delivery of messages in near real-time to more than 100 different communicationdevices, in over 200 countries and territories, in 15 languages and dialects – all simultaneously. We delivered 1.5 billion communications in 2016. Weautomate the process of sending contextual notifications to multiple constituencies and receiving return information on a person’s or operation’s status sothat organizations can act quickly and precisely. Our Critical Event Management platform is comprised of a comprehensive set of software applications thataddress the full spectrum of tasks an organization has to perform to manage a critical event, including Mass Notification, Incident Management, SafetyConnection, IT Alerting, Visual Command Center, Crisis Commander, Community Engagement and Secure Messaging. We believe that our broad suite ofintegrated, enterprise applications delivered via a single global platform is a significant competitive advantage in the market for Critical Event Managementsolutions, which we refer to generally as CEM.In critical situations, the speed at which threats are assessed and information is transmitted and accessed is essential. For example, United States Departmentof Homeland Security research indicates that the average duration of an active shooter event at a school is approximately 12.5 minutes, while the averagepolice response time to such events is 18 minutes. Accordingly, organizations must be able to aggregate multiple types of threat and incident data anddetermine whether their people, assets, or suppliers could be impacted, rapidly deliver messages that are tailored to multiple, specific audiences, in preciselocations and be assured of delivery. Further, the proliferation of mobile and digital communications has resulted in individuals spending less time in a fixedoffice location, with International Data Corporation estimating that by 2020 mobile workers will account for 72% of the total United States workforce, andthis trend has simultaneously increased the number of pathways through which people receive information. These developments have made it imperative thatorganizations be able to locate travelling or remote workers to determine who might be impacted by a critical event, and that critical communications bedelivered via voice, SMS, and email, as well as to social media, outdoor signage and personal computers. Moreover, organizations require the ability toleverage all of these pathways, individually or in sequence, to reach people in situations where a certain means of communication may be inoperative orindividuals are not responsive to a single pathway. During public safety threats and critical business events, the ability to gather, organize and analyze datain real time, and to enable secure, scalable, reliable and automated communications to people can be essential to saving lives, protecting assets andmaintaining businesses. Further, the ability to rapidly organize a response by locating available responders and reducing the time required to manage themvia automated communications can also result in significant economic savings, as each minute of unplanned downtime costs organizations an average ofapproximately $5,600, according to Gartner, Inc.The severity, complexity and frequency of these critical events, their implications for business performance and personal safety, and regulatory andcompliance challenges are increasing. The need for active shooter preparedness and public safety protection from terrorist attacks, as well managing theresponse to IT outages, cyber incidents, severe weather conditions, product recalls, supply-chain interruptions, hazardous material discharges and otherurgent events, drive the need for a secure, scalable and reliable CEM system that can be operated quickly and easily. In addition, there has been a rapidproliferation of connected devices and networked physical objects – the Internet of Things, or IoT – that have the capability to communicate informationabout status and environment and generate data that enables individuals and enterprises to take appropriate action. These dynamics have led to a growingneed for solutions that can deliver comprehensive yet targeted and contextually relevant content that facilitates the desired outcomes in critical situationsand overcomes the information overload that individuals face. We estimate, based on data from Frost & Sullivan, presented in an independent studycommissioned by us, and data from Markets and Markets, that the market for CEM solutions represented an $18.3 billion worldwide opportunity in 2015 andis expected to grow to $41.1 billion in 2020.2 Following the tragic events of 9/11, Everbridge was founded with a vision of helping people communicate effectively in critical situations. Our SaaS-basedCEM platform is built on a secure, scalable and reliable infrastructure with multiple layers of redundancy to enable the rapid delivery of criticalcommunications, with near real-time verification, over numerous devices and contact paths. Our Mass Notification application is our most establishedapplication and enables enterprises and governmental entities to aggregate and assess threat data, locate people based on their standard work or homelocation and send and receive two-way, contextually aware notifications to individuals or groups to keep them informed before, during and after natural orman-made disasters and other emergencies. For example, during Hurricane Sandy, our Mass Notification application was used along the U.S. East Coast todeliver more than eight million communications. By automating the delivery of these types of critical communications, we enable customers to increase thespeed and accuracy of their response and reduce associated costs. Importantly, given the pressure and anxiety most people experience in critical situations,our Mass Notification application provides a simple user interface and automated workflows for ease of use. The expertise that we garnered developing ourMass Notification application and our customers’ reliance on our solutions led us to leverage our platform to deploy solutions for CEM use cases. In turn, wehave developed a full suite of enterprise-scale applications that enable our customers to inform and organize people during critical situations, whether abroad audience or a targeted subset of individuals, globally or locally, and accounting for cultural, linguistic, regulatory and technological differences. As allof our applications leverage our CEM platform, customers can use a single contacts database, rules engine of algorithms and hierarchies and user interface toaccomplish multiple objectives. Our applications are easy-to-use, quickly deployable and require limited implementation services and no developmentresources.The following situations reflect examples of how our applications aggregate and assess data and enable improved management of critical events: •When an active shooter situation or terrorist attack occurs, organizations can quickly identify employees in the affected area, includingemployees not at their usual business location, in order to confirm that they are safe and provide tailored instructions. For example, shelter-in-place instructions may be provided to people in an impacted building while evacuation instructions are provided to those in an adjacentbuilding. At the same time, first responders and hospitals can use multiple modes of alerting to mobilize resources and call in staff to provideemergency care. •When a hurricane is imminent, local emergency management departments can alert affected communities with relevant safety and evacuationinstructions while companies can put in place emergency plans to notify employees of office closures while coordinating work assignmentsto maintain the continuity of core operations. •Companies can consolidate separate command centers for emergency operations and supply chain events, using one common data set toaggregate and assess data on severe weather, political unrest and other types of threats to their own and suppliers’ operations, therebyreducing costs while gaining efficiencies. •When IT systems fail, IT administrators can shorten the time required to alert cross-department responders, use scheduling information todetermine availability and quickly assemble appropriate personnel on a conference bridge, thereby reducing the costs incurred fromdowntime. •When a patient is suspected of having a stroke, an on-call specialist can provide a patient assessment via video communications during theambulance trip and the emergency room can be readied for an immediate stroke treatment, accelerating critical time to treatment. •When a cyber incident shuts down an IT network, management can alert employees of the network shutdown via a secure, alternatecommunication path. •When a power line is down, utility workers can utilize pre-configured incident management templates to alert affected customers andresponders and provide service updates. •When engine readings in critical equipment detect a malfunction, technicians with the appropriate skills can be automatically alerted andquickly deployed to minimize downtime and avoid revenue loss or service interruption.3 •When readings from an implanted medical device are abnormal, that information can be automatically routed to the individual’s healthcareprovider to enable timely medical care. •When a young child goes missing, local officials can send alerts to and receive tips from their communities to aid in locating and returningthe child. •When a financial services firm experiences disruptions in service, clients can be promptly notified and audit confirmations can be providedto document delivery.Our customer base has grown from 867 customers at the end of 2011 to more than 3,200 customers as of December 31, 2016. As of December 31, 2016, ourcustomers were based in 28 countries and included eight of the 10 largest U.S. cities, eight of the 10 largest U.S.-based investment banks, 24 of the 25 busiestNorth American airports, six of the 10 largest global consulting firms, six of the 10 largest global auto makers, all four of the largest global accounting firms,four of the 10 largest U.S.-based health care providers and four of the 10 largest U.S.-based health insurers.

Our customers span a widevariety of industries including technology, energy, financial services, healthcare and life sciences, manufacturing, media and entertainment, retail, highereducation and professional services.We derive substantially all of our revenue from subscriptions to our critical communications applications, which represented 96%, 97% and 97% of our totalrevenue in 2016, 2015 and 2014, respectively. Historically, we derived more than 86% of our revenue in each of the last three fiscal years from sales of ourMass Notification application. Our pricing model is based on the number of applications subscribed to and, per application, the number of people, locationsand things connected to our platform, as well as the volume of communications. We also offer premium services including data feeds for social media, threatintelligence and weather. We generate additional revenue by expanding the number of applications, number of contacts and number of devices that ourcustomers purchase over time.Recent DevelopmentsIn September 2016, we closed our initial public offering, or IPO, in which we sold a total of 6,250,000 shares of our common stock. We received net cashproceeds of $66.1 million, net of underwriting discounts and commissions and other costs associated with the offering paid or payable by us.In December 2016, we acquired 100% of the shares of Svensk Krisledning AB, or Crisis Commander. We acquired Crisis Commander for cash considerationof approximately $2.3 million with additional time and performance-based milestones that could result in additional payments of $0.4 million. CrisisCommander is a SaaS mobile crisis management company operating out of Sweden.In January 2017, we acquired 100% of the shares of IDV Solutions, LLC, or IDV. We acquired IDV for cash consideration of approximately $21.3 million,with additional time and performance-based milestones that could result in additional payments of $6.2 million. IDV is a provider of threat assessment andoperational visualization software located in Lansing, Michigan.Industry BackgroundOver the past two decades, methods to assess critical events and to automate and accelerate the process of managing and responding to such events haveevolved rapidly, in tandem with advances in technology, to include automated or system-generated responses, including voice calls, text messages, emails,social media and outdoor digital signage. In critical situations, the speed at which information is transmitted and accessed is essential.Key Trends Driving a Fundamental Shift in CommunicationsGovernmental entities and enterprises face increasing threats to the safety of their geographically disparate and constantly mobile residents and employees.According to the Global Terrorism Database, the number of global fatalities and injuries from terrorist acts has increased 400% from 2005 to 2015, and theworld has witnessed4 devastating attacks in Orlando, Berlin, Brussels, Nice, San Bernardino, Istanbul and other global cities. According to estimates by the Institute for Economicsand Peace, the economic cost of terrorism reached $52.9 billion in 2014. In addition, according to the Third National Climate Assessment prepared by theU.S. Global Change Research Program, the United States has been experiencing severe weather events above long-term averages, with, for example, thenumber of heat waves in 2011 and 2012 at nearly triple the long-term average. Similarly, a PricewaterhouseCoopers study found that the number of cybersecurity incidents across all industries rose by 38% in 2015 versus the prior year and Lloyd’s estimates that cyber-attacks cost businesses as much $400billion annually. Taken together, global reinsurer Swiss Reinsurance Company Ltd. found that the cost of disaster events, including man-made and severeweather incidents, reached $85 billion worldwide in 2015.At the same time, key business and technology trends continue to shift both the fundamental way that organizations communicate with relevant stakeholdersand how individuals regularly consume information. People increasingly consume most of their information through mobile devices and applications as wellas through social media and other digital channels. Increasingly, less information is shared using traditional “analog” communication methods, such asprinted media, television and landline telephones. The proliferation of mobile and digital communications, as well as the emergence of the IoT, hasaccelerated the speed at which people communicate, exponentially increasing the volume of communications that individuals must process. As a result ofthese dynamics, it has become imperative that communications be appropriately contextualized, meaningful and actionable.In light of these trends, communications have become one of the most important areas of technology investment. In a 2016 report, Gartner, Inc. estimates that$1.4 trillion, or 41.0%, of information technology, or IT, expenditure was for communications in 2016. Organizations are reaping the benefits of digitalcommunications to more easily and relevantly interact with their target constituents including customers, partners, employees, residents and other keystakeholders. Likewise, as IT innovation continues to shift to on-demand models, organizations have increasingly migrated from on-premises software tocloud-based solutions in order to improve agility and efficiency when seeking to communicate with their global, mobile, distributed stakeholders.In order to connect people across disparate communication modalities in diverse locations, organizations are increasingly investing in technologies thatunify different analog and digital real-time and non-real-time communications. The integration of real-time enterprise communication services such as instantmessaging and voice and video conferencing with non-real-time communication services such as voicemail, facsimile and e-mail can provide a consistentand unified user experience across multiple devices and media types.During public safety threats and critical business events, the ability to communicate life-saving or damage-mitigating information is crucial. Speed, security,scalability and reliability of communications is essential. The severity, complexity and frequency of these critical events, their implications for personalsafety or business performance and rising regulatory and compliance challenges are driving demand for CEM solutions, which we estimate, based on datafrom Frost & Sullivan, presented in an independent study commissioned by us, and data from Markets and Markets, represented an $18.3 billion worldwidemarket opportunity in 2015.Evolution of Critical Event Management SolutionsTraditional solutions for critical communications have not kept pace with the increasingly digital world, the evolving threat landscape and the opportunityto leverage technological innovation to more effectively communicate with people. These solutions are often developed in-house or are not truly enterprisegrade in scale and reliability, leaving many organizations to use analog, manual, one-way and people-based modalities to communicate with relevantstakeholders. These solutions lack the scale to reliably address the breadth of the different critical challenges that organizations increasingly face, thesophistication required to address evolving needs with aggregated data and analysis for threat assessment, automated workflows and the ability to rapidlydeliver messages that are contextually tailored to multiple, specific audiences, in precise locations, using a variety of different communication modalities.Traditional critical communication solutions also typically send notifications based upon a person’s static work or home address. Given the mobile nature oftoday’s workforce, solutions now need to be able to dynamically locate who is near a critical event and send instructions to impacted parties and respondersbased upon where they actually are.5 CEM solutions build upon the strengths of modern critical communications. Organizations today typically manage critical events across the organization insilos that use disparate data sources and unintegrated tools, making it difficult to achieve a common operational view of threats and of the status of response.Utilizing a common contact base, consistent rules engines, threat databases that are integrated with information on the location of an organization’s people,assets and suppliers, and a common visualization platform, CEM solutions can provide a more integrated solution which can improve management controland visibility and lower costs. The ability to cohesively and rapidly share information and collaborate across the organization underlies creating a commonoperational approach.Requirements of Effective Critical Event Management SolutionsIn order to deliver effective critical communications solutions, several requirements must be met: •Comprehensive Solution. Organizations require an enterprise-scale, comprehensive solution that can provide them with aggregated data andautomated workflows and deliver intelligent, contextual messages across multiple communications modalities – all operated from desktop ormobile devices to accommodate managing critical events whenever they occur. •Scalability and Speed. Organizations require a solution that is agile and flexible enough to reach individuals at both high volume/lowfrequency intervals, such as emergency mass notification situations, and low volume/high frequency intervals, such as for IT alerting andsecure messaging. •Enterprise-Grade Reliability. Given the inherent nature of critical events, organizations require a solution that is robust, resilient and highlyredundant, with a high level of assured uptime and a low degree of fault tolerance. •Situational Assessment. Organizations require ready access to information from weather feeds, threat sources and IT monitoring systems, aswell as the ability to incorporate trends from social media and feedback from their personnel in the field, in order to assess critical events andimpacted areas. •Dynamic Location Capability. With today’s mobile workforce, organizations need to be able to locate and instruct impacted people, andidentify and organize responders, based on where they actually are, not just based on their static office or home location. •Visualization. Organizations require a visualization platform that integrates threat and incident data from a wide variety of sources, as well asupdates on the status of incident response tasks, in order to improve their ability to assess the potential impact of events and the success ofmitigation strategies, and to improve management control. •Security and Regulatory Compliance. Organizations require a solution that is architected to ensure data and communications security giventhe significance of the content being managed and the regulatory requirements that apply to the sensitive data being communicated. •Intelligent Communication and Contextual Personalization. Organizations require sophisticated, intelligent technology that can tailorboth the content of communications and the modalities through which they are delivered based on differing individual preferences and rolesand responsibilities within the organization. •Ease-of-Use. Given the need for speed and the pressure and anxiety most people experience in critical situations, organizations require asolution that is simple and easy-to-use, particularly when lives and property are at risk. •Real-Time and After-Event Reporting and Analytics. To ensure that organizations can measure and improve performance around criticalevents, a solution should provide detailed, timely and compliant reporting and analytics on organizational responsiveness and theeffectiveness of communications. •Global Reach and Local Expertise. Global communications require a “local” approach to deal with the complexity of varying culturalpreferences, languages and device types, as well as technical and regulatory requirements.6 Key Benefits of Our Solutions and Competitive StrengthsEverbridge was founded with a vision to help organizations communicate quickly and reliably to deliver the right message to the right people, on the rightdevice, in the right location, at the right time during public safety threats and critical business events. Our CEM solutions enable organizations to assessthreats, locate impacted people and assets, and manage and respond to critical events, all on a single platform Key benefits of our solutions and competitivestrengths include the following: •Comprehensive, Enterprise-Scale Platform. The core of our solutions is our critical communications platform, which provides multiplelayers of redundancy to assure uptime and delivery of communications regardless of volume or throughput requirements. The platform issecure, scalable and reliable, enabling the delivery and verification of tens of millions of different communications virtually anywhere, inany volume, in near real-time.

Our SaaS-based applications are out-of-the box, enterprise-ready and can be utilizedwithout customer development, testing or ongoing maintenance. Regardless of a customer or prospect’s size or needs, our applications arebuilt to scale to its largest and most complex critical communications requirements. •Aggregated Threat Data and Analysis. Our software gathers and analyzes information from weather data feeds, public safety and threat datafeeds, social media, IT ticketing systems and monitoring systems, as well as inputs and feedback from two-way and polling messages. Datacan be geo-mapped and threat and incident data can be used to automatically trigger simple or complex workflows that are tied to standardoperating procedures or run-books. •Contextual Communications. We enable intelligence and personalization in the critical communications process by delivering contextualcommunications. Our customers can deliver and escalate critical communications broadly to a mass population or to a targeted subset ofindividuals based on geographic location, skill level, role and communication modality preferences for rich, two-way collaboration. •Dynamic Location Awareness. Our platform can provide organizations with the ability to send and receive notifications based on the lastknown locations of people, not just based on a static office or home address. Our platform integrates with a variety of sources of locationinformation, including building access control systems and corporate network access solutions. This location-specific approach enablesorganizations to quickly determine which individuals may be affected by a public safety threat or able to respond to a critical business event,and to provide targeted and relevant instructions and two- way communications. •Large, Dynamic and Rich Communications Data Asset. As of December 31, 2016, our data asset consists of our contacts databases thatmanage approximately 130 million contact profiles and connections from more than 3,200 customers based in 28 countries. Our contactsdatabases, which we refer to as contact stores, are initially created through an upload of contacts from the customer and are automaticallyupdated with the most current contact information provided by the customer or by individuals who opt-in to receive notifications from ourCommunity Engagement application. Our contact stores are repositories for all contact details, attributes and business rules and preferences,such as a person’s last-known location, language spoken, special needs, technical certifications and on-call status. •Multi-channel Visualization. Our platform provides the ability to create an integrated view of threats, incidents and the status of response, allwithin the context of the locations of an organization’s people, assets and suppliers. Multiple channels of information can be displayed side-by-side so different facets of a critical event can be monitored simultaneously, and the same data can be displayed on personal computerscreens and on a large command center wall to provide flexibility in deployment.7 •Robust Security, Industry Certification and Compliance. Our platform is built on a secure and resilient infrastructure with multiple layers ofredundancy. Many of our enterprise applications are designed to meet rigorous security and compliance requirements for financial servicesfirms, healthcare institutions, the U.S. federal government and other regulated industries, including facilitating compliance with FINRA andHIPAA standards. Our solutions received designation under the Support Anti-terrorism by Fostering Effective Technology Act of 2002, orSAFETY Act, and certification by U.S. Department of Homeland Security that places us on the approved product list for homeland security.Our solutions are also accredited under the Federal Information Security Management Act of 2002, or FISMA. •Automated Workflows. Our platform automates the workflows required to complete a critical notification, including establishing theindividuals within an organization authorized to send messages, the groups of stakeholders to whom messages will be sent and the content ofmessages to be sent to different groups of relevant stakeholders, in each case based on incident type. We believe that this automation reducesthe amount of time required to send critical notification as well as the associated cost. Our platform also enables customers to automaticallyestablish procedures for improving the success of communication efforts. •Globally Local. Our platform is designed to be utilized globally while accounting for local cultural, linguistic, regulatory and technologicaldifferences. We have relationships with suppliers and carriers in multiple countries to ensure delivery in compliance with local, technical andregulatory requirements.

Our platform is highly flexible and can support the development of newapplications to meet evolving safety and operational challenges. For example, our Safety Connection application enables organizations tolocate people and send them notifications based on their dynamic last known location, while actively incorporating threat and other data toallow for targeted and relevant communications. While the historic market for corporate security and safety solutions has been focused onestablishing perimeters – locks, alarms and guards – to keep threats to employees outside of the physical premises, our solutions areresponsive to the dramatic shift towards an increasingly mobile workforce where employees spend less time in traditional offices. At the sametime, protection of employees at traditional places of business remains crucial. Market research completed in 2016 by us together withEmergency Management & Safety Solutions, found that while organizations were very concerned about the risk of workplace violence, 79%said they were at best only somewhat prepared for an active shooter event, and communicating with people in an impacted building was seenas the biggest challenge. In light of these dynamics, we intend to continue to develop new applications for use cases in a variety of newmarkets and to leverage our platform and our existing customer relationships as a source of new applications, industry use cases, features andsolutions. •Expand Our International Footprint. We intend to continue to expand our local presence in regions such as Europe, the Middle East andAsia to leverage our relationships with local carriers and our ability to deliver messages to over 200 countries and territories in 15 languagesand dialects as well as expand our channel partnerships and also to opportunistically consider expanding in other regions. •Maintain Our Technology and Thought Leadership. We will continue to invest in our core CEM platform and our applications to maintainour technology leadership position. For example, we believe that we are the only company today that provides a full, integrated CEMsolution and that we provide the first solution to offer dynamic versus static location awareness integrated with analysis and communicationsfor the employee safety and security marketplace. Further, we believe we have a competitive advantage through our commitment toinnovation and thought leadership that has enabled us to take market share from our competitors and accelerate our growth. •Opportunistically Pursue Acquisitions. We plan to selectively pursue acquisitions of complementary businesses, technologies and teamsthat allow us to penetrate new markets and add features and functionalities to our platform.Our Market OpportunityThere is a significant demand for CEM solutions that meet the above requirements. We estimate, based on data from Frost & Sullivan, presented in anindependent study commissioned by us, and data from Markets and Markets, that the market for CEM solutions represented an $18.3 billion worldwideopportunity in 2015. This consists of an estimated addressable market of $7.3 billion in North America and $11.0 billion outside of North America. As theadoption of targeted and contextually aware CEM solutions continues to expand and take hold across a broader cross-section of organizations and industryverticals, we estimate, based on data from Frost & Sullivan, presented in an independent study commissioned by us, and data from Markets and Markets, thatour addressable market will grow at a compound annual growth rate of 17.5% to $41.1 billion in 2020.More specifically, Markets and Markets estimates that the aggregate market for mass notification software and services was $1.7 billion in 2015 and isprojected to grow at a compound annual growth rate of 20.9% to $4.4 billion in 2020. Within the market for mass notification software and services, Marketsand Markets estimates that the distributed recipient solutions segment was $713 million in 2015, and is projected to grow at a compound annual growth rateof 24.8% to $2.6 billion in 2021.

This engine is designed to address both the emergency and operationalcomponents of a critical communications program, and is capable of providing two-way communications and verified delivery in accordance with ourcustomers’ escalation policies. Our critical communications engine has multi-modal communications reach, including redundant global SMS and voicedelivery capabilities, and is designed to comply with local, technical and regulatory requirements, which we believe has provided us with a competitiveadvantage. For example, we believe that our early deployment of local SMS codes intended to comply with rules established by the Telecom RegulatoryAuthority of India allowed us to increase our SMS delivery success rates in India. Our CEM platform builds on the strengths of this critical communicationsengine, adding capabilities for integrated threat assessment, visualization, incident management and analytics.Additional core technical attributes of our platform include: •Monitors more than 100 types of threat data for situation assessment. •Multi-tenant architecture that supports multiple layers of redundancy to maximize uptime and delivery of critical content, regardless ofvolume or throughput requirements. •Dynamic spatial/geographic information system capability to geo-target communications by zip code, street address or a specific radius froma location. •Support for two-way communications and alerting on over 100 different devices and endpoints, including landline and wireless phones,hand-held communication and other voice-capable devices, satellite, SMS, two-way radios, outdoor digital signage, sirens and internetenabled devices. •Designed to meet rigorous security and compliance requirements for financial services firms, healthcare institutions, the U.S. federalgovernment and other regulated industries, including facilitating compliance with health care requirements such as HIPAA privacy andsecurity standards. •Extensive set of APIs and configuration capabilities to allow customers and partners to easily integrate our platform with other systems. OurAPIs’ two-way invocation capabilities enable third-party systems to flexibly and easily integrate with our platform. •Multi-channel visualization capabilities support integrated views of threats, incidents and status of response to improve managementvisibility and control. •Supports easy-to-use native mobile applications, including multiple secure mobile applications for message initiation, management andreporting. •Supports push notifications and two-way conversations that enable mobile users to send and receive secure messages such as text, pictures,videos and the users’ current geographic locations.Our Contact StoresOur contact stores manage approximately 130 million contact profiles and connections from more than 3,200 customers based in 28 countries as ofDecember 31, 2016, up from 15 million contact profiles as of December 31, 2012. They are initially created through an upload of contacts from the customerand are automatically updated with the most current contact information provided by the customer or by individuals who opt-in to receive notification fromour Community Engagement application. Our contact stores are simultaneously enriched by geographic, situational and other real-time data. Our contactstores are repositories for all contact details, attributes and business rules and preferences, such as a person’s last-known location, language spoken, specialneeds, technical certifications and on-call status.10 We leverage the data contained in our contact stores in a number of significant ways. Our data asset across multiple verticals enables us to develop bestpractices for reaching the intended contact, on the correct device, at the right location, at the appropriate time. We also use these data to better understand ourcustomer base and their emerging use cases in order to improve our existing applications and develop new applications.Everbridge Publishing NetworkAn important component of our platform is our Everbridge Publishing Network, which allows our customers to share relevant situational awarenessinformation with each other. Public safety agencies, for example, can publish information to the Everbridge Publishing Network about incidents that mightprove disruptive to the movement of people, goods and services for businesses within a certain area. If any of those businesses are also customers of ours, theywill receive this information from a source they know is vetted and reliable, and will be able to take timely steps to mitigate or remediate the situation.Our ApplicationsThrough our CEM platform, we deliver reliable enterprise-ready applications that provide organizations with the ability to assess threats, locate people,automate actions, monitor incident response, and deliver contextual communications in any volume, in near-real time. We have designed our applications’user interface to be easy to use. We understand that since some of our applications will be utilized to manage complex situations or to send large volumes ofmessages to key stakeholders during stressful situations, streamlining the user interface to reduce user errors and anxiety is essential. We conduct extensiveusability testing and design reviews with our stakeholders, and have applied in our designs the lessons learned over more than a decade of working withcritical communications users and professionals.Our applications enable: •Communications to key stakeholders during emergency situations. •Corporate communications with customers and employees. •Automated outreach to on-call personnel. •Integrated threat assessment and visualization. •Workgroup collaboration on mobile devices. •Integration of physical security data with location awareness data gathered from travel, network and access systems to rapidly find andcommunicate with employees during disruptive events. •Securely designed and efficiently implemented communications among healthcare providers and patients. •Community engagement and collaboration with citizens and businesses. •Critical IoT communications between machines and from machines to people •Mobile response plan deployment and management of incidence response.11 Our applications include: •Mass Notification. Our secure, scalable and reliable Mass Notification application is our most established application and enablesenterprises and governmental entities to send contextually aware notifications to individuals or groups to keep them informed before, duringand after natural or man-made disasters and other emergencies. We provide robust analytics, map-based targeting, flexible groupmanagement, distributed contact data, language localization, multiple options for contact data management and a globally-optimizedapproach to voice and SMS routing. We also support community engagement functionality, which provides a direct link between residentsand emergency management departments with the goal of fostering public safety. •Safety Connection. Our Safety Connection application enables organizations to send notifications based on dynamic last known location ofan individual, including the airport, street, building floor or conference room at which the individual was most recently present, whileactively incorporating threat and other data to allow for targeted and relevant communications. When fully deployed, the application canalso aggregate near real-time data from multiple sources, including building access control systems, wired and wireless network accesspoints, travel management systems and mobile application check-ins. We believe that Safety Connection represents a significant advance inhelping organizations use critical communications to keep their constituents safe, as many current solutions use only static office andresidential locations that are not sufficiently location-aware relative to an increasingly mobile workforce. •Incident Management. Our Incident Management application enables organizations to automate workflows and make their communicationscontextually relevant using drag and drop business rules to determine who should be contacted, how they should be contacted and whatinformation is required. We believe that this application decreases costly human errors and reduces downtime, while simultaneouslycapturing required compliance information. We also support cross-account collaboration and situational intelligence sharing during crisesfor corporations and communities. •IT Alerting. Our IT Alerting application enables IT professionals to alert and communicate with key members of their teams during an ITincident or outage, including during a cyber security breach. The application integrates with IT service management platforms, includingServiceNow, and uses automatic escalation of alerts, on-call scheduling and mobile alerting to automate manual tasks and keep IT teamscollaborating during an incident. We also provide real-time shift calendars with integrated on-call notifications to help users better manageemployee resources and get the right message to the right person, at the right time through automated staffing. Taken together, our ITAlerting application has the potential to provide meaningful savings to organizations by reducing mean-time-to-repair. Each minute ofunplanned downtime costs organizations an average of approximately $5,600, according to Gartner, while 59% of Fortune 500 companiesexperience 1.6 hours of downtime per week, according to Dunn & Bradstreet. IHS, Inc. estimates information and communication technologydowntime costs North American organizations $700 billion per year. •Visual Command Center. Our Virtual Command Center application enables customers to monitor and integrate more than 100 types of threatdata, as well as information on internal incidents, to generate and visualize an alert when potential risks occur within proximity of anorganization’s physical locations, suppliers, assets or people. The solution improves the ability to more quickly understand and assess theimpact of threats, execute the correct response, and monitor on-going resolution in order to mitigate risk to personnel safety, businesscontinuity, assets and supply chain operations. •Community Engagement. Our Community Engagement application integrates emergency management and community outreach byproviding local governments with a unified solution to connect residents to their public safety department, public information resources, andneighbors via social media and mobile applications. This creates a stronger and more engaged community improving the communicationreach for emergency personnel, while providing residents with real-time emergency and community information, and allows residents toanonymously opt-in and provide tips. For example, the City of Philadelphia experienced a 70% increase in opt-ins in 2015 with ourCommunity Engagement application. 12 •Crisis Commander. Our Crisis Commander application provides mobile access to crisis, recovery and brand protection plans, as well as thecapability to manage a crisis or event through role-based assignments and status updates. Organizations can enhance their overall crisismanagement efforts by making plans readily available to responders on the most popular mobile platforms regardless of their location. Theapplication also simplifies updating plans for changes to personnel or processes, and enhances visibility into response progress during acritical event. •Secure Messaging. Our Secure Messaging application meets the compliance and security requirements of organizations that need to providean alternative way for their employees to communicate and share nonpublic information. A tailored version of our Secure Messagingapplication, CareConverge, is designed for medical professionals and facilitates HIPAA-compliant communications without the need forpagers and other single use devices, supporting the development of a “connected” hospital. CareConverge also facilitates telemedicine byallowing medical professionals to hold video conferences with patients and other medical professionals as well as share medical imaging, labresults and other critical information. Our Secure Messaging application also enables financial services organizations’ employees andcustomers to securely communicate via text, voice, and video, while remaining FINRA compliant.Our TechnologyThe design and development of our applications, and our critical communication and critical event management platforms include the following keyattributes: •Robust, Enterprise-Grade Scalability and Reliability. Given the mission-critical nature of our solutions, our multi-tenant platform wasdesigned to provide a robust, high level of resiliency, scalability and redundancy. We use multiple geographically distributed serviceproviders and communications carriers to achieve a high degree of redundancy, fault tolerance and cost-effective operations. We havemultiple layers of redundancy and a horizontal scaling model across our infrastructure to deliver high availability and performance. Ourredundant data centers are located in Los Angeles, California; Denver, Colorado; San Francisco, California; Dallas, Texas; St. Louis,Missouri; and Toronto, Canada as well as in Germany, the United Kingdom and the Netherlands. Similarly, we leverage redundantdownstream communications providers to enable our services to remain uninterrupted even if a particular provider encounters technicaldifficulties. •Multi-Modal, Globally Local Communications Delivery. We optimize international call routing across hundreds of telecommunicationsproviders to enable higher voice quality, improved delivery rates during emergencies and the ability to configure local caller IDs to improverecognition and answer rates. We also work with multiple SMS providers to identify regulatory hurdles and deploy and actively manage anoptimal mix of national and international SMS codes to ensure high delivery and response rates. •Security and Compliance. Our security and data protection policies and controls are based on the Federal Information Security ManagementAct risk management framework defined by the National Institute of Standards and Technology, or NIST, special publication, or SP, 800-37.To meet the rigorous standards of our enterprise and government customers, an independent and accredited third-party security assessmentfirm annually verifies our compliance with over 800 security and data protection requirements detailed in NIST SP 800-53. Through thisprocess, we map our compliance with other security and data privacy frameworks including ISO 27001 and HIPAA. In addition, we holdcertifications including SysTrust Statement on Standards for Attestation Engagements No. 16, Service Operations Controls 2 & 3.We havealso been awarded approvals by DHS that enable us to receive priority treatment for vital voice and data circuits or other telecommunicationsservices. More recently, our critical communications solutions received designation under the SAFETY Act and certification by DHS thatplaces us on the approved product list for homeland security and provides us with the highest level of liability protection available under theSAFETY Act. The certification similarly protects our customers from legal liability claims arising from acts of terrorism, as contemplated bythe SAFETY Act. Further, our solutions are accredited under FISMA and we are certified under the EU-US Privacy Shield to meet regulatoryrequirements governing the processing of European Union residents’ personal data outside of the European Union.13 •Hybrid Infrastructure. To provide highly scalable and global solutions, we employ redundant, geographically diverse productionimplementations of our platform infrastructure in multiple SOC 2-compliant data center facilities in North America and Europe. Within eachdata center, we utilize a hybrid-cloud architecture that enables us to leverage both proprietary and third-party infrastructure services toenable “on-demand” capacity and performance without substantial upfront investment. Our hybrid-cloud architecture enables our customersto select the location in which to store their contact data, allowing for compliance with local and international data privacy laws. Ourarchitecture also enables our platform to dynamically determine the best location from which to deliver critical communications on behalf ofour customers and solves many international communications delivery challenges by utilizing in-country or in-region telephony, messagingand data communication providers. Our infrastructure is continuously maintained and monitored by dedicated engineers based in redundantnetwork operations centers in the Los Angeles and Boston areas. •Dynamic Location Detection. Our platform can create and update dynamic data sets containing a contact’s last-known location, includingthe airport, street, building floor or conference room at which the contact was most recently present. Multiple data sources can be aggregatedincluding building access control and badging systems, wired and wireless network access points, and corporate travel management andoffice hoteling systems. These data are used to best locate a contact in an emergency or critical business situation, independent of thecontact’s home or office location. Contacts can also share their location via a three-in-one mobile panic button application, which sends apanic message to the applicable organization’s security team, and also includes the ability to send audio and video content, to check-in tocapture and report geo-location data and to establish a safe corridor through a potentially unsafe area.Our Comprehensive Customer Support ServicesWe are committed to the success of our customers.

Research anddevelopment expense totaled $14.8 million, $11.5 million and $7.4 million for 2016, 2015 and 2014, respectively.18 Our CompetitionThe market for CEM solutions is highly fragmented, intensely competitive and constantly evolving. We compete with an array of established and emergingcompanies, many of whom are single product or single market focused, as well as in-house solutions. With the introduction of new technologies and marketentrants, we expect the competitive environment to remain intense going forward. The primary competitors for our Mass Notification and IncidentManagement applications include: BlackBerry Limited, Emergency Communications Network, F24 AG, Enera Inc., Nuance Communications, Inc., SWNCommunications Inc. and SunGard Data Systems Inc. The primary competitors for our IT Alerting application include: PagerDuty, Inc. and xMatters, Inc. Theprimary competitors for our Secure Messaging application include: DocHalo, LLC, Spok, Inc., Perfect Serve, Inc. and TigerText, Inc. With respect to ourrecent acquisitions, the primary competitors for our Visual Command Center and Crisis Commander applications include Planet Risk Inc. and In Case ofCrisis, respectively.We compete on the basis of a number of factors, including: •product functionality, including local and multi-modal delivery in international markets; •breadth of offerings; •performance, security, scalability and reliability; •compliance with local regulations and multi-language support; •brand recognition, reputation and customer satisfaction; •ease of implementation, use and maintenance; and •total cost of ownership.We believe that we compete favorably with respect to all of these factors and that we are well positioned as a leading provider of targeted and contextuallyrelevant critical communications.Intellectual PropertyOur future success and competitive position depend in part on our ability to protect our intellectual property and proprietary technologies. To safeguardthese rights, we rely on a combination of patent, trademark, copyright and trade secret laws and contractual protections in the United States and otherjurisdictions.As of December 31, 2016, we had 14 issued patents and four patent applications pending in the United States. We also had one issued patent in Canada. Wecannot assure you that any patents will issue from any patent applications, that patents that issue from such applications will give us the protection that weseek or that any such patents will not be challenged, invalidated, or circumvented. Any patents that may issue in the future from our pending or future patentapplications may not provide sufficiently broad protection and may not be enforceable in actions against alleged infringers.We have registered the “Everbridge” and “Nixle” names in the United States, and have registered the “Everbridge” name in the European Union. We haveregistrations and/or pending applications for additional marks in the United States; however, we cannot assure you that any future trademark registrationswill be issued for pending or future applications or that any registered trademarks will be enforceable or provide adequate protection of our proprietary rights.We also license software from third parties for integration into our offerings, including open source software and other software available on commerciallyreasonable terms. We cannot assure you that such third parties will maintain such software or continue to make it available.We are the registered holder of a variety of domestic and international domain names that include everbridge.com, as well as similar variations on that name.19 In order to protect our unpatented proprietary technologies and processes, we rely on trade secret laws and confidentiality agreements with our employees,consultants, vendors and others. Despite our efforts to protect our proprietary technology and trade secrets, unauthorized parties may attempt tomisappropriate, reverse engineer or otherwise obtain and use them. In addition, others may independently discover our trade secrets, in which case we wouldnot be able to assert trade secret rights, or develop similar technologies and processes. Further, the contractual provisions that we enter into may not preventunauthorized use or disclosure of our proprietary technology or intellectual property rights and may not provide an adequate remedy in the event ofunauthorized use or disclosure of our proprietary technology or intellectual property rights.If we become more successful, we believe that competitors will be more likely to try to develop solutions that are similar to ours and that may infringe ourproprietary rights. It may also be more likely that competitors or other third parties will claim that our solutions infringe their proprietary rights.Patent and other intellectual property disputes are common in our industry and we have been involved in such disputes from time to time in the ordinarycourse of our business. Some companies, including some of our competitors, own large numbers of patents, copyrights and trademarks, which they may use toassert claims against us. Third parties may in the future assert claims of infringement, misappropriation or other violations of intellectual property rightsagainst us. They may also assert such claims against our customers whom we typically indemnify against claims that our solution infringes, misappropriatesor otherwise violates the intellectual property rights of third parties. As the numbers of products and competitors in our market increase and overlaps occur,claims of infringement, misappropriation and other violations of intellectual property rights may increase. Any claim of infringement, misappropriation orother violation of intellectual property rights by a third party, even those without merit, could cause us to incur substantial costs defending against the claimand could distract our management from our business.Government RegulationWe are subject to a number of U.S. federal and state and foreign laws and regulations that involve matters central to our business. These laws and regulationsmay involve privacy, data protection, intellectual property, competition, consumer protection, export taxation or other subjects. Many of the laws andregulations to which we are subject are still evolving and being tested in courts and could be interpreted in ways that could harm our business. In addition,the application and interpretation of these laws and regulations often are uncertain, particularly in the new and rapidly evolving industry in which weoperate. Because global laws and regulations have continued to develop and evolve rapidly, it is possible that we may not be, or may not have been,compliant with each such applicable law or regulation.Culture and EmployeesWe believe that our culture has been a key contributor to our success to-date and that the critical nature of the solutions that we provide promotes a sense ofgreater purpose and fulfillment in our employees. We have invested in building a strong corporate culture and believe it is one of our most important andsustainable sources of competitive advantage.As of December 31, 2016, we had 467 full-time employees, including 98 in data center operations and customer support, 182 in sales and marketing, 123 inresearch and development and 64 in general and administrative. As of December 31, 2016, we had 360 full-time employees in the United States and 107 full-time employees internationally. None of our U.S. employees are covered by collective bargaining agreements. We believe our employee relations are goodand we have not experienced any work stoppages.20 FacilitiesOur principal executive offices are located in Burlington, Massachusetts, where we occupy an approximately 45,000 square-foot facility under a leaseexpiring on May 31, 2022, and in Pasadena, California, where we occupy an approximately 19,000 square-foot facility under a lease expiring on June 30,2018. We also have offices in San Francisco, California; Lansing, Michigan; Windsor, United Kingdom; Colchester, United Kingdom, Norsburg, Sweden andBeijing, China.Legal ProceedingsFrom time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently aparty to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business,operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlementcosts, diversion of management resources and other factors.SegmentsWe view our operations and manage our business as one operating segment.

Risk Factors.Our operations and financial results are subject to various risks and uncertainties including those described below. You should consider carefully the risksand uncertainties described below, in addition to other information contained in this Annual Report on Form 10-K, including our consolidated financialstatements and related notes, as well as our other public filings with the Securities and Exchange Commission. The risks and uncertainties described beloware not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also becomeimportant factors that adversely affect our business. If any of the following risks or others not specified below materialize, our business, financial conditionand results of operations could be materially adversely affected. In that case, the trading price of our common stock could decline.Risks Related to Our Business and Our IndustryIf our business does not grow as we expect, or if we fail to manage our growth effectively, our operating results and business prospects would suffer.We increased our number of full-time employees from 303 to 418 to 467 as of December 31, 2014, 2015 and 2016, respectively. In 2016, we made asignificant investment in our sales organization, growing our headcount by 16%, and our revenue increased by $18.1 million for the year endedDecember 31, 2016 compared to 2015, due in part to the increase in our customer base.However, our business may not continue to grow as quickly or at all in the future, which would adversely affect our revenue and business prospects. Ourbusiness growth depends on a number of factors including: •our ability to execute upon our business plan effectively; •our ability to accelerate our acquisition of new customers; •our ability to further sell to our existing customers new applications and features and to additional departments in their organizations; •our ability to develop new applications to target new markets and use cases; •our ability to expand our international footprint; •the growth of the market in which we operate; •our ability to maintain our technology leadership position; and •our ability to acquire complementary business, technologies and teams we need.Further, our growth has placed, and will continue to place, a strain on our managerial, operational, financial and other resources, and our future operatingresults depend to a large extent on our ability to successfully manage our anticipated expansion and growth. To manage our growth successfully and handlethe responsibilities of being a public company, we believe we must effectively, among other things: •increase our customer base and upsell and cross-sell additional and new applications to our existing customers; •invest in sales and marketing and expand our channel partner relationships; •develop new applications that target new markets and use cases; •expand our international operations; and •improve our platform and applications, financial and operational systems, procedures and controls.We intend to continue our investment in sales and marketing, platform and applications, research and development, and general and administrative functionsand other areas to grow our business. We are likely to recognize the costs associated with these investments earlier than some of the anticipated benefits andthe return on these investments may be lower, or may develop more slowly, than we expect, which could adversely affect our operating results.22 If we are unable to manage our growth effectively in a manner that preserves the key aspects of our corporate culture, we may not be able to take advantage ofmarket opportunities or develop new applications or upgrades to our existing applications and we may fail to satisfy customer requirements, maintain thequality and security of our applications, execute on our business plan or respond to competitive pressures, which could result in our financial results sufferingand a decline in our stock price.We have not been profitable on a consistent basis historically and may not achieve or maintain profitability in the future.We have posted a net loss in each year since inception, including net losses of $11.3 million, $10.8 million and $0.6 million in the years ended December 31,2016, 2015, 2014, respectively. As of December 31, 2016, we had an accumulated deficit of $89.6 million. While we have experienced significant revenuegrowth in recent periods and profitability solely in the quarters ended March 31, 2014, June 30, 2014 and September 30, 2014, we are not certain whether orwhen we will obtain a high enough volume of sales of our applications to sustain or increase our growth or achieve or maintain profitability in the future. Wealso expect our costs to increase in future periods, which could negatively affect our future operating results if our revenue does not increase. In particular, weexpect to continue to expend substantial financial and other resources on: •sales and marketing, including a significant expansion of our sales organization, both domestically and internationally; •research and development related to our platform and applications, including investments in our research and development team; •continued international expansion of our business; and •general and administration expenses, including legal and accounting expenses related to being a public company.These investments may not result in increased revenue or growth in our business. If we are unable to increase our revenue at a rate sufficient to offset theexpected increase in our costs, our business, financial position and results of operations will be harmed, and we may not be able to achieve or maintainprofitability over the long term. Additionally, we may encounter unforeseen operating expenses, difficulties, complications, delays and other unknownfactors that may result in losses in future periods. If our revenue growth does not meet our expectations in future periods, our financial performance may beharmed, and we may not achieve or maintain profitability in the future.To date, we have derived substantially all of our revenue from the sale of our Mass Notification application. If we are unable to renew or increase sales ofthis application, or if we are unable to increase sales of our other applications, our business and operating results could be adversely affected.While we have recently introduced five new critical communications applications, one of which was introduced in the middle of 2014, three of which wereintroduced in 2015 and one of which was introduced in 2016, we derived 86%, 91% and 96% of our revenue from sales of our Mass Notification applicationin 2016, 2015 and 2014, respectively, and expect to continue to derive a substantial portion of our revenue from sales of this application in the near term. Asa result, our operating results could suffer due to: •any decline in demand for our Mass Notification application; •pricing or other competitive pressures from competing products; •the introduction of applications and technologies that serve as a replacement or substitute for, or represent an improvement over, our MassNotification application; •technological innovations or new standards that our Mass Notification application do not address; and •sensitivity to current or future prices offered by us or competing solutions.23 Because of our reliance on our Mass Notification application, our inability to renew or increase sales of this application or a decline in prices of thisapplication would harm our business and operating results more seriously than if we derived significant revenue from a variety of applications. Any factoradversely affecting sales of our historical or new applications, including release cycles, market acceptance, competition, performance and reliability,reputation and economic and market conditions, could adversely affect our business and operating results.If we are unable to develop upgrades to our platform, develop new applications, sell our platform and applications into new markets or further penetrateour existing market, our revenue may not grow.Our ability to increase sales will depend in large part on our ability to enhance and improve our platform and applications, introduce new applications in atimely manner, develop new use cases for our platform and further penetrate our existing market. The success of any enhancement to our platform or newapplications depends on several factors, including the timely completion, introduction and market acceptance of enhanced or new applications, the ability tomaintain and develop relationships with channel partners and communications carriers, the ability to attract, retain and effectively train sales and marketingpersonnel and the effectiveness of our marketing programs. Any new application that we develop or acquire may not be introduced in a timely or cost-effective manner, and may not achieve the broad market acceptance necessary to generate significant revenue. Any new markets into which we attempt to sellour applications, including new vertical markets and new countries or regions, may not be receptive. Our ability to further penetrate our existing marketsdepends on the quality of our platform and applications and our ability to design our platform and applications to meet consumer demand. Any failure toenhance or improve our platform and applications as well as introduce new applications may adversely affect our revenue growth and operating results.If we are unable to attract new customers or sell additional applications to our existing customers, our revenue and revenue growth will be harmed.A part of our growth strategy is to add new customers and sell additional applications to our existing customers. Our ability to maintain existing customers,sell them new applications and to add new customers will depend in significant part on our ability to anticipate industry evolution, practices and standardsand to continue to introduce and enhance the applications we offer on a timely basis to keep pace with technological developments. However, we may proveunsuccessful in developing new applications and improving existing applications. In addition, the success of any new application depends on several factors,including the timely completion, introduction and market acceptance of the application. Any new applications we develop or acquire might not beintroduced in a timely or cost-effective manner and might not achieve the broad market acceptance necessary to generate significant revenue. If any of ourcompetitors implements new technologies before we are able to implement them or better anticipates market opportunities, those competitors may be able toprovide more effective or cheaper products than ours. As a result, we may be unable to renew our agreements with existing customers, attract new customers orgrow or maintain our business from existing customers, which could harm our revenue and growth.Failure to effectively develop and expand our sales and marketing capabilities could harm our ability to increase our customer base and achieve broadermarket acceptance of our platform and applications.To increase total customers and achieve broader market acceptance of our platform and applications, we will need to expand our sales and marketingorganization, including the vertical and geographic distribution of our salesforce and our teams of account executives focused on new accounts, accountmanagers responsible for renewal and growth of existing accounts, and business development representatives targeting new and growth business opportunitycreation. We will continue to dedicate significant resources to our global sales and marketing organizations. The effectiveness of our sales and marketingteams has varied over time and may vary in the future, and depends in part on our ability to maintain and improve our platform and applications. All of theseefforts will require us to invest significant financial and other resources and we are unlikely to see the benefits, if any, of these increases until future periodsafter incurring these expenses. Our business will be seriously harmed if our efforts do not generate a correspondingly significant increase in revenue. We maynot achieve revenue growth from expanding our salesforce if we are unable to hire, develop and retain talented sales personnel, if our new sales personnel areunable to achieve desired productivity levels in a reasonable period of time or if our sales and marketing programs are not effective.24 The nature of our business exposes us to inherent liability risks.Our applications, including our Mass Notification, Incident Management, IT Alerting, Safety Connection, Community Engagement, Visual CommandCenter, Crisis Commander and Secure Messaging applications, are designed to communicate life-saving or damage-mitigating information to the rightpeople, on the right device, in the right location, at the right time during public safety threats and critical business events. Due to the nature of suchapplications, we are potentially exposed to greater risks of liability for employee acts or omissions or system failures than may be inherent in otherbusinesses. Although substantially all of our customer agreements contain provisions limiting our liability to our customers, we cannot assure you that theselimitations will be enforced or the costs of any litigation related to actual or alleged omissions or failures would have a material adverse effect on us even ifwe prevail. Further, certain of our insurance policies and the laws of some states may limit or prohibit insurance coverage for punitive or certain other types ofdamages or liability arising from gross negligence and we cannot assure you that we are adequately insured against the risks that we face.Because we generally recognize revenue ratably over the term of our contract with a customer, downturns or upturns in sales will not be fully reflected inour operating results until future periods.Our revenue is primarily generated from subscriptions to our critical communications applications. Our customers do not have the right to take possession ofour software platform and applications. Revenue from subscriptions, including additional fees for items such as incremental usage, is recognized ratably overthe subscription period beginning on the date that the subscription is made available to the customer. Our agreements with our customers typically rangefrom one to three years. As a result, much of the revenue that we report in each quarter is attributable to agreements entered into during previous quarters.Consequently, a decline in sales, customer renewals or market acceptance of our applications in any one quarter would not necessarily be fully reflected inthe revenue in that quarter, and would negatively affect our revenue and profitability in future quarters. This ratable revenue recognition also makes itdifficult for us to rapidly increase our revenue through additional sales in any period, as revenue from new customers generally is recognized over theapplicable agreement term.We operate in an emerging and evolving market, which may develop more slowly or differently than we expect. If our market does not grow as we expect,or if we cannot expand our platform and applications to meet the demands of this market, our revenue may decline, fail to grow or fail to grow at anaccelerated rate, and we may incur operating losses.The market for CEM solutions is in an early stage of development, and it is uncertain whether this market will develop, and even if it does develop, howrapidly or how consistently it will develop or whether our platform and applications will be accepted into the markets in which we operate and plan tooperate. Our success will depend, to a substantial extent, on the widespread adoption of our platform and applications as an alternative to historical massnotification systems. Some organizations may be reluctant or unwilling to use our platform and applications for a number of reasons, including concernsabout additional costs, uncertainty regarding the reliability and security of cloud-based offerings or lack of awareness of the benefits of our platform andapplications. Many organizations have invested substantial personnel and financial resources to integrate traditional on-premise applications into theirbusinesses, and therefore may be reluctant or unwilling to migrate to cloud-based applications. Our ability to expand sales of our platform and applicationsinto new markets depends on several factors, including the awareness of our platform and applications; the timely completion, introduction and marketacceptance of enhancements to our platform and applications or new applications that we may introduce; our ability to attract, retain and effectively trainsales and marketing personnel; our ability to develop relationships with channel partners and communication carriers; the effectiveness of our marketingprograms; the costs of our platform and applications; and the success of our competitors. If we are unsuccessful in developing and marketing our platform andapplications into new markets, or if organizations do not perceive or value the benefits of our platform and applications, the market for our platform andapplications might not continue to develop or might develop more slowly than we expect, either of which would harm our revenue and growth prospects.25 Our estimates of market opportunity and forecasts of market growth may prove to be inaccurate, and even if the market in which we compete achieves theforecasted growth, our business could fail to grow at similar rates, if at all.Market opportunity estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may not prove to beaccurate. Our estimates and forecasts relating to the size and expected growth of our addressable market may prove to be inaccurate. Even if the market inwhich we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all.The markets in which we participate are competitive, and if we do not compete effectively, our operating results could be harmed.The market for critical communications solutions is highly fragmented, competitive and constantly evolving. With the introduction of new technologies andmarket entrants, we expect that the competitive environment in which we compete will remain intense going forward. Some of our competitors have made ormay make acquisitions or may enter into partnerships or other strategic relationships to provide a more comprehensive offering than they individually hadoffered or achieve greater economies of scale. In addition, new entrants not currently considered to be competitors may enter the market through acquisitions,partnerships or strategic relationships. We compete on the basis of a number of factors, including: •application functionality, including local and multi-modal delivery in international markets; •breadth of offerings; •performance, security, scalability and reliability; •compliance with local regulations and multi-language support; •brand recognition, reputation and customer satisfaction; •ease of application implementation, use and maintenance; and •total cost of ownership.We face competition from in-house solutions, large integrated systems vendors and established and emerging cloud and SaaS and other software providers.Our competitors vary in size and in the breadth and scope of the products and services offered. Many of our competitors and potential competitors havegreater name recognition, longer operating histories, more established customer relationships, larger marketing budgets and greater resources than we do.While some of our competitors provide a platform with applications to support one or more use cases, many others provide point-solutions that address asingle use case. Further, other potential competitors not currently offering competitive applications may expand their offerings to compete with our solutions.Our competitors may be able to respond more quickly and effectively than we can to new or changing opportunities, technologies, standards and customerrequirements. An existing competitor or new entrant could introduce new technology that reduces demand for our solutions. In addition to application andtechnology competition, we face pricing competition. Some of our competitors offer their applications or services at a lower price, which has resulted inpricing pressures. Some of our larger competitors have the operating flexibility to bundle competing applications and services with other offerings, includingoffering them at a lower price as part of a larger sale. For all of these reasons, we may not be able to compete successfully and competition could result inreduced sales, reduced margins, losses or the failure of our applications to achieve or maintain market acceptance, any of which could harm our business.We may not be able to scale our business quickly enough to meet our customers’ growing needs and if we are not able to grow efficiently, our operatingresults could be harmed.As usage of our platform and applications grows, we will need to continue making significant investments to develop and implement new applications,technologies, security features and cloud-based infrastructure operations. In addition, we will need to appropriately scale our internal business systems andour services organization, including customer support and professional services, to serve our growing customer base, particularly as our customerdemographics change over time. Any failure of, or delay in, these efforts could impair the performance of our platform and applications and reduce customersatisfaction. Even if we are able to upgrade our systems and26 expand our staff, any such expansion may be expensive and complex, requiring management’s time and attention. To the extent that we do not effectivelyscale our platform and operations to meet the growing needs of our customers, we may not be able to grow as quickly as we anticipate, our customers mayreduce or cancel use of our applications and professional services, we may be unable to compete effectively and our business and operating results may beharmed.Our quarterly results of operations may fluctuate, and if we fail to meet or exceed the expectations of investors or securities analysts, our stock price coulddecline.Our quarterly revenue and results of operations have historically varied from period to period, and we expect that they will continue to do so as a result of avariety of factors, including many that are outside of our control. Our future revenue is difficult to predict. Our expense levels are relatively fixed in the shortterm and are based, in part, on our expectations as to future revenue. If revenue levels are below our expectations, we may incur higher losses and may neverattain or maintain consistent profitability. Our operating results may be disproportionately affected by a reduction in revenue because a proportionatelysmaller amount of our expenses varies with our revenues. If our quarterly revenue or results of operations fall below the expectations of investors or securitiesanalysts, the price of our common stock could decline substantially. Fluctuations in our results of operations may be due to a number of factors, including: •fluctuations in demand for our platform and applications; •changes in our business or pricing policies in response to competitive pricing actions or otherwise; •the timing and success of introductions of new applications or upgrades to our platform; •the impact of acquisition transaction-related amortization expenses and other certain expenses on our gross profit; •competition, including entry into the industry by new competitors and new offerings by existing competitors; •changes in the business or pricing policies of our competitors; •the amount and timing of expenditures, including those related to expanding our operations, increasing research and development,enhancing our platform, introducing new applications or growing our sales and marketing teams; •our ability to effectively manage growth within existing and new markets, both domestically and internationally; •changes in the payment terms for our applications; •our ability to successfully manage any future acquisitions of businesses or technologies; •the strength of regional, national and global economies; and •the impact of natural disasters or man-made problems such as cyber incidents and terrorism.Due to the foregoing factors and the other risks discussed in this Annual Report on Form 10-K, you should not rely on quarter-to-quarter comparisons of ourresults of operations as an indication of our future performance nor should you consider our recent revenue growth or results in any single period to beindicative of our future performance.Interruptions or delays in service from our third-party data center providers could impair our ability to make our platform and applications available toour customers, resulting in customer dissatisfaction, damage to our reputation, loss of customers, limited growth and reduction in revenue.We currently serve part of our platform functions from third-party data center hosting facilities operated by Century Link and located in the Los Angeles,California and Denver, Colorado areas. In addition, we serve ancillary functions for our customers from third-party data center hosting facilities operated byInteroute located in the United Kingdom, Germany and the Netherlands, and by Elastichost in Toronto, Canada. We also rely on Amazon Web Serviceslocated in California and Virginia to host certain of our platform functions and applications. Our operations27 depend, in part, on our third-party facility providers’ abilities to protect these facilities against damage or interruption from natural disasters, power ortelecommunications failures, cyber incidents, criminal acts and similar events. In the event that any of our third-party facilities arrangements are terminated,or if there is a lapse of service or damage to a facility, we could experience interruptions in our platform as well as delays and additional expenses inarranging new facilities and services. Any changes in third-party service levels at our data centers or any errors, defects, disruptions, cyber incidents or otherperformance problems with our solutions could harm our reputation.Any damage to, or failure of, the systems of our third-party providers could result in interruptions to our platform. Despite precautions taken at our datacenters, the occurrence of spikes in usage volume, natural disasters, cyber incidents, acts of terrorism, vandalism or sabotage, closure of a facility withoutadequate notice or other unanticipated problems could result in lengthy interruptions in the availability of our platform and applications. Problems faced byour third-party data center locations, with the telecommunications network providers with whom they contract, or with the systems by which ourtelecommunications providers allocate capacity among their customers, including us, could adversely affect the experience of our customers. Because of thenature of the services that we provide to our customers during public safety threats and critical business events, any such interruption may arise when ourcustomers are most reliant on our applications, thereby compounding the impact of any interruption on our business. Interruptions in our services mightreduce our revenue, cause us to issue refunds to customers and subject us to potential liability.Further, our insurance policies may not adequately compensate us for any losses that we may incur in the event of damage or interruption. Although webenefit from liability protection under the Support Anti-Terrorism by Fostering Effective Technology Act of 2002, the occurrence of any of the foregoingcould reduce our revenue, subject us to liability, cause us to issue credits to customers or cause customers not to renew their subscriptions for ourapplications, any of which could materially adversely affect our business.Failures or reduced accessibility of third-party software on which we rely could impair the availability of our platform and applications and adverselyaffect our business.We license software from third parties for integration into our platform and applications, including open source software. These licenses might not continueto be available to us on acceptable terms, or at all. While we are not substantially dependent upon any third-party software, the loss of the right to use all or asignificant portion of our third-party software required for the development, maintenance and delivery of our applications could result in delays in theprovision of our applications until we develop or identify, obtain and integrate equivalent technology, which could harm our business.Any errors or defects in the hardware or software we use could result in errors, interruptions, cyber incidents or a failure of our applications. Any significantinterruption in the availability of all or a significant portion of such software could have an adverse impact on our business unless and until we can replacethe functionality provided by these applications at a similar cost. Furthermore, this software may not be available on commercially reasonable terms, or at all.The loss of the right to use all or a significant portion of this software could limit access to our platform and applications. Additionally, we rely upon thirdparties’ abilities to enhance their current applications, develop new applications on a timely and cost-effective basis and respond to emerging industrystandards and other technological changes. We may be unable to effect changes to such third-party technologies, which may prevent us from rapidlyresponding to evolving customer requirements. We also may be unable to replace the functionality provided by the third-party software currently offered inconjunction with our applications in the event that such software becomes obsolete or incompatible with future versions of our platform and applications oris otherwise not adequately maintained or updated.If we do not or cannot maintain the compatibility of our platform with third-party applications that our customers use in their businesses, our revenue willdecline.As a significant percentage of our customers choose to integrate our solutions with certain capabilities provided by third-party providers, the functionalityand popularity of our solutions depend, in part, on our ability to integrate our platform and applications with certain third-party systems. Third-partyproviders may change the features of their technologies, restrict our access to their applications or alter the terms governing use of their applications in anadverse manner. Such changes could functionally limit or terminate our ability to use these third-party technologies28 in conjunction with our platform and applications, which could negatively impact our solutions and harm our business. If we fail to integrate our solutionswith new third-party applications that our customers use, we may not be able to offer the functionality that our customers need, which would negativelyimpact our ability to generate revenue and adversely impact our business.Changes in the mix of sizes or types of businesses or government agencies that purchase our platform and applications purchased or used by our customerscould affect our operating results.We have sold and will continue to sell to enterprises of all sizes, municipal and regional governmental agencies, non-profit organizations, educationalinstitutions and healthcare organizations. Sales to larger organizations may entail longer sales cycles and more significant selling efforts. Selling to smallbusinesses may involve greater credit risk and uncertainty. Changes in the sizes or types of businesses that purchase our applications could cause ouroperating results to be adversely affected.If our, our customers’ or our third-party providers’ security measures are compromised or unauthorized access to the data of our customers or theiremployees, customers or constituents is otherwise obtained, our platform may be perceived as not being secure, our customers may be harmed and maycurtail or cease their use of our applications, our reputation may be damaged and we may incur significant liabilities.Our operations involve the storage and transmission of data of our customers and their employees, customers and constituents, including personallyidentifiable information such as contact information and physical location. Security incidents, whether as a result of third-party action, employee or customererror, technology impairment or failure, malfeasance or criminal activity, could result in unauthorized access to, or loss or unauthorized disclosure of, thisinformation, litigation, indemnity obligations and other possible liabilities, as well as negative publicity, which could damage our reputation, impair oursales and harm our customers and our business. Cyber incidents and malicious internet-based activity continue to increase generally, and providers of cloud-based services have been targeted. If third parties with whom we work, such as vendors or developers, violate applicable laws or our security policies, suchviolations may also put our customers’ information at risk and could in turn have an adverse effect on our business. We may be unable to anticipate orprevent techniques used to obtain unauthorized access or to sabotage systems because they change frequently and often are not detected until after anincident has occurred. As we increase our customer base and our brand becomes more widely known and recognized, third parties may increasingly seek tocompromise our security controls or gain unauthorized access to our sensitive corporate information or customers’ data. Further, because of the nature of theservices that we provide to our customers during public safety threats and critical business events, we may be a unique target for attacks.Many governments have enacted laws requiring companies to notify individuals of data security incidents or unauthorized transfers involving certain typesof personal data. In addition, some of our customers contractually require notification of any data security incident. Accordingly, security incidentsexperienced by our competitors, by our customers or by us may lead to public disclosures, which may lead to widespread negative publicity. Any securitycompromise in our industry, whether actual or perceived, could harm our reputation, erode customer confidence in the effectiveness of our security measures,negatively impact our ability to attract new customers, cause existing customers to elect not to renew their subscriptions or subject us to third-party lawsuits,regulatory fines or other action or liability, which could materially and adversely affect our business and operating results. Further, the costs of compliancewith notification laws and contractual obligations may be significant and any requirement that we provide such notifications as a result of an actual oralleged compromise could have a material and adverse effect on our business.While we maintain general liability insurance coverage and coverage for errors or omissions, we cannot assure you that such coverage would be adequate orwould otherwise protect us from liabilities or damages with respect to claims alleging compromises of personal data or that such coverage will continue to beavailable on acceptable terms or at all.29 If our applications fail to function in a manner that allows our customers to operate in compliance with regulations and/or industry standards, our revenueand operating results could be harmed.Certain of our customers require applications that ensure secure communications given the nature of the content being distributed and associated applicableregulatory requirements. In particular, our healthcare customers rely on our applications to communicate in a manner that is designed to comply with therequirements of the Health Insurance Portability and Accountability Act of 1996, the 2009 Health Information Technology for Economic and Clinical HealthAct, the Final Omnibus Rule of January 25, 2013, which are collectively referred to as HIPAA, and which impose privacy and data security standards thatprotect individually identifiable health information by limiting the uses and disclosures of individually identifiable health information and requiring thatcertain data security standards be implemented to protect this information. As a “business associate” to “covered entities” that are subject to HIPAA, we alsohave our own compliance obligations directly under HIPAA and pursuant to the business associate agreements that we are required to enter into with ourcustomers that are HIPAA-covered entities.Governments and industry organizations may also adopt new laws, regulations or requirements, or make changes to existing laws or regulations, that couldimpact the demand for, or value of, our applications. If we are unable to adapt our applications to changing legal and regulatory standards or otherrequirements in a timely manner, or if our applications fail to allow our customers to communicate in compliance with applicable laws and regulations, ourcustomers may lose confidence in our applications and could switch to products offered by our competitors, or threaten or bring legal actions against us.In addition, governmental and other customers may require our applications to comply with certain privacy, security or other certifications and standards. Forinstance, with regard to transfers of personal data, the EU-US Safe Harbor program, which provided a valid legal basis for transfers of personal data fromEurope to the United States, was invalidated in October 2015, which has a significant impact on the transfer of data from the European Union to U.S.companies, including us. We are certified under the EU-US Privacy Shield, the successor regime to the EU-US Safe Harbor. While we now have Privacy Shieldcertification and other legally recognized mechanisms in place that we believe allow for the lawful transfer of EU customer and employee information to theUnited States, it is possible that these mechanisms may also be challenged or evolve to include new legal requirements that could have an impact on how wemove this data. If our applications fail to maintain compliance with these certifications and standards, or our competitors achieve compliance with thesecertifications and standards, we may be disqualified from selling our applications to such customers, or may otherwise be at a competitive disadvantage,either of which would harm our business, results of operations and financial condition. If our policies and practices are, or are perceived to be, insufficient orif our customers have concerns regarding the transfer of data from the European Union to the United States, we could be subject to enforcement actions orinvestigations by EU Data Protection Authorities or lawsuits by private parties, and our business could be negatively impacted.If we fail to offer high-quality customer support, our business and reputation may suffer.We offer our customers implementation services and 24/7 support through our customer support centers as well as education, professional development andcertification through Everbridge University as well as a range of consulting services. Consulting service offerings include onsite implementation packages,Certified Emergency Management professional operational reviews, dedicated client care representatives, custom web-based training, and development ofclient-specific communications materials to increase internal awareness of system value.Providing this education, training and support requires that our personnel who manage our training resources or provide customer support have specificexperience, knowledge and expertise, making it more difficult for us to hire qualified personnel and to scale up our support operations. The importance ofhigh-quality customer support will increase as we expand our business and pursue new customers and larger organizations. We may be unable to respondquickly enough to accommodate short-term increases in customer demand for support services or scale our services if our business grows. We also may beunable to modify the format of our support services or change our pricing to compete with changes in support services provided by our competitors. Increasedcustomer demand for these services, without corresponding revenue, could increase our costs and harm our operating results. If we do not help our customersuse applications within our platform and provide effective ongoing support, our ability to sell additional applications to, or to retain, existing customers maysuffer and our reputation with existing or potential customers may be harmed.30 Our strategy includes pursuing acquisitions, and our potential inability to successfully integrate newly-acquired technologies, assets or businesses mayharm our financial results. Future acquisitions of technologies, assets or businesses, which are paid for partially or entirely through the issuance of stockor stock rights, could dilute the ownership of our existing stockholders.We may evaluate and consider potential strategic transactions, including acquisitions of, or investments in, businesses, technologies, services, products andother assets in the future. We also may enter into relationships with other businesses to expand our platform and applications, which could involve preferredor exclusive licenses, additional channels of distribution, discount pricing or investments in other companies.We have acquired businesses and technology in the past. For example, we acquired Vocal Limited in March 2014, the assets of Nixle, LLC in December2014, technology from Tapestry Telemed LLC in December 2014, Svensk Krisledning AB in December 2016 and IDV Solutions LLC in January 2017. Webelieve that part of our continued growth will be driven by acquisitions of other companies or their technologies, assets, businesses and teams. Anyacquisitions we complete will give rise to risks, including: •incurring higher than anticipated capital expenditures and operating expenses; •failing to assimilate the operations and personnel or failing to retain the key personnel of the acquired company or business; •failing to integrate the acquired technologies, or incurring significant expense to integrate acquired technologies, into our platform andapplications; •disrupting our ongoing business; •diverting our management’s attention and other company resources; •failing to maintain uniform standards, controls and policies; •incurring significant accounting charges; •impairing relationships with our customers and employees; •finding that the acquired technology, asset or business does not further our business strategy, that we overpaid for the technology, asset orbusiness or that we may be required to write off acquired assets or investments partially or entirely; •failing to realize the expected synergies of the transaction; •being exposed to unforeseen liabilities and contingencies that were not identified prior to acquiring the company; and •being unable to generate sufficient revenue and profits from acquisitions to offset the associated acquisition costs.Fully integrating an acquired technology, asset or business into our operations may take a significant amount of time. We may not be successful inovercoming these risks or any other problems encountered with acquisitions. To the extent that we do not successfully avoid or overcome the risks orproblems related to any such acquisitions, our results of operations and financial condition could be harmed. Acquisitions also could impact our financialposition and capital requirements, or could cause fluctuations in our quarterly and annual results of operations. Acquisitions could include significantgoodwill and intangible assets, which may result in future impairment charges that would reduce our stated earnings. We may incur significant costs in ourefforts to engage in strategic transactions and these expenditures may not result in successful acquisitions.We expect that the consideration we might pay for any future acquisitions of technologies, assets, businesses or teams could include stock, rights to purchasestock, cash or some combination of the foregoing. If we issue stock or rights to purchase stock in connection with future acquisitions, net income per shareand then-existing holders of our common stock may experience dilution.31 We rely on the performance of our senior management and highly skilled personnel, and if we are unable to attract, retain and motivate well-qualifiedemployees, our business and results of operations could be harmed.We believe our success has depended, and continues to depend, on the efforts and talents of senior management and key personnel, including JaimeEllertson, our President, Chief Executive Officer and Chairman of our board of directors, Kenneth S. Goldman, our Senior Vice President and Chief FinancialOfficer, and Imad Mouline, our Senior Vice President and Chief Technology Officer. Our future success depends on our continuing ability to attract, develop,motivate and retain highly qualified and skilled employees. Qualified individuals are in high demand, and we may incur significant costs to attract them. Inaddition, the loss of any of our senior management or key personnel could interrupt our ability to execute our business plan, as such individuals may bedifficult to replace. If we do not succeed in attracting well-qualified employees or retaining and motivating existing employees, our business and results ofoperations could be harmed.Uncertain or weakened global economic conditions may adversely affect our industry, business and results of operations.Our overall performance depends on domestic and worldwide economic conditions, which may remain challenging for the foreseeable future. Financialdevelopments seemingly unrelated to us or to our industry may adversely affect us and our planned international expansion. The U.S. economy and other keyinternational economies have been impacted by threatened sovereign defaults and ratings downgrades, falling demand for a variety of goods and services,restricted credit, threats to major multinational companies, poor liquidity, reduced corporate profitability, volatility in credit, equity and foreign exchangemarkets, bankruptcies and overall uncertainty. These conditions affect the rate of information technology spending and could adversely affect our customers’ability or willingness to purchase our applications and services, delay prospective customers’ purchasing decisions, reduce the value or duration of theirsubscriptions or affect renewal rates, any of which could adversely affect our operating results. We cannot predict the timing, strength or duration of theeconomic recovery or any subsequent economic slowdown worldwide, in the United States, or in our industry.Any future litigation against us could be costly and time-consuming to defend.We have in the past and may in the future become subject, from time to time, to legal proceedings and claims that arise in the ordinary course of businesssuch as claims brought by our customers in connection with commercial disputes or employment claims made by our current or former employees. Litigationmight result in substantial costs and may divert management’s attention and resources, which might seriously harm our business, overall financial conditionand operating results. Insurance might not cover such claims, might not provide sufficient payments to cover all the costs to resolve one or more such claimsand might not continue to be available on terms acceptable to us. A claim brought against us that is uninsured or underinsured could result in unanticipatedcosts, thereby reducing our operating results and leading analysts or potential investors to reduce their expectations of our performance, which could reducethe trading price of our stock.Because our long-term growth strategy involves further expansion of our sales to customers outside the United States, our business will be susceptible torisks associated with international operations.A component of our growth strategy involves the further expansion of our operations and customer base internationally. We opened our first internationaloffice in Beijing, China in April 2012 and subsequently opened an office in Windsor, United Kingdom in September 2012 as part of our geographicexpansion. In March 2014, we acquired Vocal Limited, a mass notification company based in Colchester, United Kingdom. In December 2016, we acquiredSvensk Krisledning AB, a SaaS mobile crisis management company based in Norsburg, Sweden. For the years ended December 31, 2016 and 2015,approximately 10% and 14% of our revenue was derived from customers located outside of the United States. We intend to further expand our local presencein regions such as Europe, the Middle East and Asia. Our current international operations and future initiatives will involve a variety of risks, including: •currency exchange rate fluctuations and the resulting effect on our revenue and expenses, and the cost and risk of entering into hedgingtransactions if we chose to do so in the future; •economic or political instability in foreign markets;32 •greater difficulty in enforcing contracts, accounts receivable collection and longer collection periods; •more stringent regulations relating to technology, including with respect to privacy, data security and the unauthorized use of, access to, ordeletion of commercial and personal information, particularly in the European Union; •difficulties in maintaining our company culture with a dispersed and distant workforce; •unexpected changes in regulatory requirements, taxes or trade laws; •differing labor regulations, especially in the European Union, where labor laws are generally more advantageous to employees as comparedto the United States, including deemed hourly wage and overtime regulations in these locations; •challenges inherent in efficiently managing an increased number of employees over large geographic distances, including the need toimplement appropriate systems, policies, benefits and compliance programs; •difficulties in managing a business in new markets with diverse cultures, languages, customs, legal systems, alternative dispute systems andregulatory systems; •limitations on our ability to reinvest earnings from operations in one country to fund the capital needs of our operations in other countries; •limited or insufficient intellectual property protection; •political instability or terrorist activities; •likelihood of potential or actual violations of domestic and international anticorruption laws, such as the U.S. Foreign Corrupt Practices Actand the U.K. Bribery Act, or of U.S. and international export control and sanctions regulations, which likelihood may increase with anincrease of sales or operations in foreign jurisdictions and operations in certain industries; and •adverse tax burdens and foreign exchange controls that could make it difficult to repatriate earnings and cash.Our limited experience in operating our business internationally increases the risk that any potential future expansion efforts that we may undertake will notbe successful. If we invest substantial time and resources to expand our international operations and are unable to do so successfully and in a timely manner,our business and operating results will suffer. We continue to implement policies and procedures to facilitate our compliance with U.S. laws and regulationsapplicable to or arising from our international business. Inadequacies in our past or current compliance practices may increase the risk of inadvertentviolations of such laws and regulations, which could lead to financial and other penalties that could damage our reputation and impose costs on us.If we cannot maintain our company culture as we grow, our success and our business may be harmed.We believe our culture has been a key contributor to our success to-date and that the critical nature of the solutions that we provide promotes a sense ofgreater purpose and fulfillment in our employees. We have invested in building a strong corporate culture and believe it is one of our most important andsustainable sources of competitive advantage. Any failure to preserve our culture could negatively affect our ability to retain and recruit personnel and toeffectively focus on and pursue our corporate objectives. As we grow and develop the infrastructure of a public company, we may find it difficult to maintainthese important aspects of our company culture. If we fail to maintain our company culture, our business may be adversely impacted.We may be subject to additional obligations to collect and remit sales tax and other taxes, and we may be subject to tax liability for past sales, whichcould harm our business.State, local and foreign jurisdictions have differing rules and regulations governing sales, use, value added and other taxes, and these rules and regulationsare subject to varying interpretations that may change over time. Further, these jurisdictions’ rules regarding tax nexus are complex and vary significantly. Ifone or more jurisdictions were to33 assert that we have failed to collect taxes for sales of applications that leverage our platform, we could face the possibility of tax assessments and audits. Asuccessful assertion that we should be collecting additional sales, use, value added or other taxes in those jurisdictions where we have not historically doneso and do not accrue for such taxes could result in substantial tax liabilities and related penalties for past sales or otherwise harm our business and operatingresults.We face exposure to foreign currency exchange rate fluctuations.As our international operations expand, our exposure to the effects of fluctuations in currency exchange rates grows. While we have primarily transacted withcustomers and vendors in U.S. dollars historically, we expect to continue to expand the number of transactions with our customers that are denominated inforeign currencies in the future. Fluctuations in the value of the U.S. dollar and foreign currencies may make our subscriptions more expensive forinternational customers, which could harm our business. Additionally, we incur expenses for employee compensation and other operating expenses at ournon-U.S. locations in the local currency for such locations. Fluctuations in the exchange rates between the U.S. dollar and other currencies could result in anincrease to the U.S. dollar equivalent of such expenses. These fluctuations could cause our results of operations to differ from our expectations or theexpectations of our investors. Additionally, such foreign currency exchange rate fluctuations could make it more difficult to detect underlying trends in ourbusiness and results of operations.We do not currently maintain a program to hedge transactional exposures in foreign currencies. However, in the future, we may use derivative instruments,such as foreign currency forward and option contracts, to hedge certain exposures to fluctuations in foreign currency exchange rates. The use of such hedgingactivities may not offset any or more than a portion of the adverse financial effects of unfavorable movements in foreign exchange rates over the limited timethe hedges are in place. Moreover, the use of hedging instruments may introduce additional risks if we are unable to structure effective hedges with suchinstruments.Our ability to raise capital in the future may be limited, and our failure to raise capital when needed could prevent us from growing.Our business and operations may consume resources faster than we anticipate. In the future, we may need to raise additional funds to invest in future growthopportunities. Additional financing may not be available on favorable terms, if at all. If adequate funds are not available on acceptable terms, we may beunable to invest in future growth opportunities, which could seriously harm our business and operating results. If we incur debt, the debt holders would haverights senior to common stockholders to make claims on our assets, and the terms of any debt could restrict our operations, including our ability to paydividends on our common stock. Furthermore, if we issue equity securities, stockholders will experience dilution, and the new equity securities could haverights senior to those of our common stock. Because our decision to issue securities in any future offering will depend on market conditions and other factorsbeyond our control, we cannot predict or estimate the amount, timing or nature of our future offerings. As a result, our stockholders bear the risk of our futuresecurities offerings reducing the market price of our common stock and diluting their interest.Our sales cycle can be unpredictable, time-consuming and costly, which could harm our business and operating results.Our sales process involves educating prospective customers and existing customers about the use, technical capabilities and benefits of our platform andapplications. Prospective customers, especially larger organizations, often undertake a prolonged evaluation process, which typically involves not only oursolutions, but also those of our competitors and lasts from four to nine months or longer. We may spend substantial time, effort and money on our sales andmarketing efforts without any assurance that our efforts will produce any sales.Events affecting our customers’ businesses may occur during the sales cycle that could affect the size or timing of a purchase, contributing to moreunpredictability in our business and operating results. As a result of these factors, we may face greater costs, longer sales cycles and less predictability in thefuture.34 Our ability to use our net operating losses to offset future taxable income may be subject to certain limitations.As of December 31, 2016, we had federal and state net operating loss carryforwards, or NOLs, of $46.2 million and $40.5 million, respectively, due to priorperiod losses, which expire in various years beginning in 2028 if not utilized. In general, under Section 382 of the Internal Revenue Code of 1986, asamended, or the Code, a corporation that undergoes an “ownership change” is subject to limitations on its ability to utilize its NOLs to offset future taxableincome. Our existing NOLs may be subject to limitations arising from previous ownership changes. Future changes in our stock ownership, some of which areoutside of our control, could result in an ownership change. There is also a risk that due to regulatory changes, such as suspensions on the use of NOLs, orother unforeseen reasons, our existing NOLs could expire or otherwise be unavailable to offset future income tax liabilities. Additionally, state NOLsgenerated in one state cannot be used to offset income generated in another state. For these reasons, we may not be able to realize a tax benefit from the use ofour NOLs, whether or not we attain profitability.Our business is subject to the risks of earthquakes, fires, floods and other natural catastrophic events and to interruption by man-made problems such ascyber incidents or terrorism.Our business and operations are vulnerable to damage or interruption from earthquakes, fires, floods, power losses, telecommunications failures, terroristattacks, acts of war, human errors, break-ins and similar events affecting us or third-party vendors we rely on, any of which could have a material adverseimpact on our business, operating results and financial condition. Acts of terrorism, which may be targeted at metropolitan areas that have higher populationdensity than rural areas, could cause disruptions in our or our customers’ businesses or the economy as a whole. Our servers and those of our third-partyvendors may also be vulnerable to cyber incidents, break-ins and similar disruptions from unauthorized tampering with our computer systems, which couldlead to interruptions, delays, loss of critical data or the unauthorized disclosure of confidential customer data. We or our customers may not have sufficientprotection or recovery plans in place, and our business interruption insurance may be insufficient to compensate us for losses that may occur. As we relyheavily on our servers, computer and communications systems, that of third parties and the Internet to conduct our business and provide high qualitycustomer service, such disruptions could have an adverse effect on our business, operating results and financial condition.Our reported financial results may be adversely affected by changes in accounting principles generally accepted in the United States.Generally accepted accounting principles in the United States are subject to interpretation by the Financial Accounting Standards Board, or FASB, the SECand various bodies formed to promulgate and interpret appropriate accounting principles. A change in these principles or interpretations could have asignificant effect on our reported financial results, and could affect the reporting of transactions completed before the announcement of a change.Impairment of goodwill and other intangible assets would result in a decrease in our earnings.Current accounting rules provide that goodwill and other intangible assets with indefinite useful lives may not be amortized but instead must be tested forimpairment at least annually. These rules also require that intangible assets with definite useful lives be amortized over their respective estimated useful livesto their estimated residual values, and reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assetsmay not be recoverable. We have substantial goodwill and other intangible assets, and we would be required to record a significant charge to earnings in ourconsolidated financial statements during the period in which any impairment of our goodwill or intangible assets is determined. Any impairment charges orchanges to the estimated amortization periods would result in a decrease in our earnings.35 Risks Related to Our Intellectual PropertyIf we fail to protect our intellectual property and proprietary rights adequately, our business could be harmed.Our future success and competitive position depend in part on our ability to protect our intellectual property and proprietary technologies. To safeguardthese rights, we rely on a combination of patent, trademark, copyright and trade secret laws and contractual protections in the United States and otherjurisdictions, some of which afford only limited protection.As of December 31, 2016, we had 14 issued patents and four patent applications pending in the United States. We also had one issued patent in Canada. Wecannot assure you that any patents will issue from any patent applications, that patents that issue from such applications will give us the protection that weseek or that any such patents will not be challenged, invalidated, or circumvented. Any patents that may issue in the future from our pending or future patentapplications may not provide sufficiently broad protection and may not be enforceable in actions against alleged infringers. In addition, we have registeredthe “Everbridge” and “Nixle” names in the United States, and have registered the “Everbridge” name in the European Union. We have registrations and/orpending applications for additional marks in the United States; however, we cannot assure you that any future trademark registrations will be issued forpending or future applications or that any registered trademarks will be enforceable or provide adequate protection of our proprietary rights.In order to protect our unpatented proprietary technologies and processes, we rely on trade secret laws and confidentiality agreements with our employees,consultants, vendors and others. Despite our efforts to protect our proprietary technology and trade secrets, unauthorized parties may attempt tomisappropriate, reverse engineer or otherwise obtain and use them. In addition, others may independently discover our trade secrets, in which case we wouldnot be able to assert trade secret rights, or develop similar technologies and processes. Further, the contractual provisions that we enter into may not preventunauthorized use or disclosure of our proprietary technology or intellectual property rights and may not provide an adequate remedy in the event ofunauthorized use or disclosure of our proprietary technology or intellectual property rights. Effective trade secret protection may not be available in everycountry in which our services are available or where we have employees or independent contractors. The loss of trade secret protection could make it easierfor third parties to compete with our solutions by copying functionality. In addition, any changes in, or unexpected interpretations of, the trade secret andemployment laws in any country in which we operate may compromise our ability to enforce our trade secret and intellectual property rights. Costly andtime-consuming litigation could be necessary to enforce and determine the scope of our proprietary rights, and failure to obtain or maintain trade secretprotection could adversely affect our competitive business position.In addition, to protect our intellectual property rights, we may be required to spend significant resources to monitor and protect these rights. Litigationbrought to protect and enforce our intellectual property rights could be costly, time-consuming and distracting to management and could result in theimpairment or loss of portions of our intellectual property. Failure to adequately enforce our intellectual property rights could also result in the impairment orloss of those rights. Furthermore, our efforts to enforce our intellectual property rights may be met with defenses, counterclaims and countersuits attacking thevalidity and enforceability of our intellectual property rights. Patent, copyright, trademark and trade secret laws offer us only limited protection and the lawsof many of the countries in which we sell our services do not protect proprietary rights to the same extent as the United States and Europe. Accordingly,defense of our trademarks and proprietary technology may become an increasingly important issue as we continue to expand our operations and solutiondevelopment into countries that provide a lower level of intellectual property protection than the United States or Europe. Policing unauthorized use of ourintellectual property and technology is difficult and the steps we take may not prevent misappropriation of the intellectual property or technology on whichwe rely. For example, in the event of inadvertent or malicious disclosure of our proprietary technology, trade secret laws may no longer afford protection toour intellectual property rights in the areas not otherwise covered by patents or copyrights. Accordingly, we may not be able to prevent third parties frominfringing upon or misappropriating our intellectual property.We may elect to initiate litigation in the future to enforce or protect our proprietary rights or to determine the validity and scope of the rights of others. Thatlitigation may not be ultimately successful and could result in substantial costs to us, the reduction or loss in intellectual property protection for ourtechnology, the diversion of our management’s attention and harm to our reputation, any of which could materially and adversely affect our business andresults of operations.36 Our failure or inability to adequately protect our intellectual property and proprietary rights could harm our business, financial condition and results ofoperations.An assertion by a third party that we are infringing its intellectual property could subject us to costly and time-consuming litigation or expensive licensesthat could harm our business and results of operations.Patent and other intellectual property disputes are common in our industry and we have been involved in such disputes from time to time in the ordinarycourse of our business. Some companies, including some of our competitors, own large numbers of patents, copyrights and trademarks, which they may use toassert claims against us. Third parties may in the future assert claims of infringement, misappropriation or other violations of intellectual property rightsagainst us. They may also assert such claims against our customers whom we typically indemnify against claims that our solution infringes, misappropriatesor otherwise violates the intellectual property rights of third parties. As the numbers of products and competitors in our market increase and overlaps occur,claims of infringement, misappropriation and other violations of intellectual property rights may increase. Any claim of infringement, misappropriation orother violation of intellectual property rights by a third party, even those without merit, could cause us to incur substantial costs defending against the claimand could distract our management from our business.As we seek to extend our platform and applications, we could be constrained by the intellectual property rights of others and it may also be more likely thatcompetitors or other third parties will claim that our solutions infringe their proprietary rights. We might not prevail in any intellectual property infringementlitigation given the complex technical issues and inherent uncertainties in such litigation. Defending such claims, regardless of their merit, could be time-consuming and distracting to management, result in costly litigation or settlement, cause development delays or require us to enter into royalty or licensingagreements. In addition, we currently have a limited portfolio of issued patents compared to our larger competitors, and therefore may not be able toeffectively utilize our intellectual property portfolio to assert defenses or counterclaims in response to patent infringement claims or litigation broughtagainst us by third parties. Further, litigation may involve patent holding companies or other adverse patent owners who have no relevant applications orrevenue and against which our potential patents provide no deterrence, and many other potential litigants have the capability to dedicate substantiallygreater resources to enforce their intellectual property rights and to defend claims that may be brought against them. If our platform or any of our applicationsexceed the scope of in-bound licenses or violate any third-party proprietary rights, we could be required to withdraw those applications from the market, re-develop those applications or seek to obtain licenses from third parties, which might not be available on reasonable terms or at all. Any efforts to re-developour platform and our applications, obtain licenses from third parties on favorable terms or license a substitute technology might not be successful and, in anycase, might substantially increase our costs and harm our business, financial condition and results of operations. If we were compelled to withdraw any of ourapplications from the market, our business, financial condition and results of operations could be harmed.We have indemnity obligations to our customers and certain of our channel partners for certain expenses and liabilities resulting from intellectualproperty infringement claims regarding our platform and our applications, which could force us to incur substantial costs.We have indemnity obligations to our customers and certain of our channel partners for intellectual property infringement claims regarding our platform andour applications. As a result, in the case of infringement claims against these customers and channel partners, we could be required to indemnify them forlosses resulting from such claims or to refund amounts they have paid to us. We also expect that some of our channel partners with whom we do not haveexpress contractual obligations to indemnify for intellectual property infringement claims may seek indemnification from us in connection with infringementclaims brought against them. We may elect to indemnify these channel partners where we have no contractual obligation to indemnify them and we willevaluate each such request on a case-by-case basis. If a channel partner elects to invest resources in enforcing a claim for indemnification against us, we couldincur significant costs disputing it. If we do not succeed in disputing it, we could face substantial liability.37 We may be subject to damages resulting from claims that our employees or contractors have wrongfully used or disclosed alleged trade secrets of theirformer employers or other parties.We have in the past and may in the future be subject to claims that employees or contractors, or we, have inadvertently or otherwise used or disclosed tradesecrets or other proprietary information of our competitors or other parties. Litigation may be necessary to defend against these claims. If we fail in defendingagainst such claims, a court could order us to pay substantial damages and prohibit us from using technologies or features that are essential to our solutions, ifsuch technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of these parties. In addition, wemay lose valuable intellectual property rights or personnel. A loss of key personnel or their work product could hamper or prevent our ability to develop,market and support potential solutions or enhancements, which could severely harm our business. Even if we are successful in defending against these claims,such litigation could result in substantial costs and be a distraction to management.The use of open source software in our platform and applications may expose us to additional risks and harm our intellectual property.Our platform and some of our applications use or incorporate software that is subject to one or more open source licenses and we may incorporate open sourcesoftware in the future. Open source software is typically freely accessible, usable and modifiable; however, certain open source software licenses require a userwho intends to distribute the open source software as a component of the user’s software to disclose publicly part or all of the source code to the user’ssoftware. In addition, certain open source software licenses require the user of such software to make any modifications or derivative works of the open sourcecode available to others on potentially unfavorable terms or at no cost. Use and distribution of open source software may entail greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or thequality of the code.The terms of many open source licenses to which we are subject have not been interpreted by U.S. or foreign courts, and accordingly there is a risk that thoselicenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to commercialize our platform and applications.In that event, we could be required to seek licenses from third parties in order to continue offering our platform and applications, to re-develop our platformand applications, to discontinue sales of our platform and applications or to release our proprietary software code in source code form under the terms of anopen source license, any of which could harm our business. Further, given the nature of open source software, it may be more likely that third parties mightassert copyright and other intellectual property infringement claims against us based on our use of these open source software programs. Litigation could becostly for us to defend, have a negative effect on our operating results and financial condition or require us to devote additional research and developmentresources to change our applications.Although we are not aware of any use of open source software in our platform and applications that would require us to disclose all or a portion of the sourcecode underlying our core applications, it is possible that such use may have inadvertently occurred in deploying our platform and applications, or thatpersons or entities may claim such disclosure to be required. Disclosing our proprietary source code could allow our competitors to create similar productswith lower development effort and time and ultimately could result in a loss of sales for us. Disclosing the source code of our proprietary software could alsomake it easier for cyber attackers and other third parties to discover vulnerabilities in or to defeat the protections of our products, which could result in ourproducts failing to provide our customers with the security they expect. Any of these events could have a material adverse effect on our business, operatingresults and financial condition. Additionally, if a third-party software provider has incorporated certain types of open source software into software we licensefrom such third party for our platform and applications without our knowledge, we could, under certain circumstances, be required to disclose the source codeto our platform and applications. This could harm our intellectual property position and our business, results of operations and financial condition.38 Risks Related to Government RegulationFailure to comply with governmental laws and regulations could harm our business.Our business is subject to regulation by various federal, state, local and foreign governments. For example, the Telephone Consumer Protection Act of 1991,or TCPA, restricts telemarketing and the use of automatic text messages without proper consent. The scope and interpretation of the laws that are or may beapplicable to the delivery of text messages are continuously evolving and developing. If we do not comply with these laws or regulations or if we becomeliable under these laws or regulations due to the failure of our customers to comply with these laws by obtaining proper consent, we could face directliability. In certain jurisdictions, these regulatory requirements may be more stringent than those in the United States. Noncompliance with applicableregulations or requirements could subject us to investigations, sanctions, enforcement actions, disgorgement of profits, fines, damages, civil and criminalpenalties, injunctions or other collateral consequences. If any governmental sanctions are imposed, or if we do not prevail in any possible civil or criminallitigation, our business, results of operations, and financial condition could be materially adversely affected. In addition, responding to any action will likelyresult in a significant diversion of management’s attention and resources and an increase in professional fees. Enforcement actions and sanctions could harmour business, reputation, results of operations and financial condition.A portion of our revenue is generated by subscriptions sold to governmental entities and heavily regulated organizations, which are subject to a number ofchallenges and risks.A portion of our revenue is generated by subscriptions sold to government entities. Additionally, many of our current and prospective customers, such asthose in the financial services, and healthcare and life sciences industries, are highly regulated and may be required to comply with more stringentregulations in connection with subscribing to and implementing our applications. Selling subscriptions to these entities can be highly competitive,expensive and time consuming, often requiring significant upfront time and expense without any assurance that we will successfully complete a sale.Furthermore, engaging in sales activities to foreign governments introduces additional compliance risks specific to the Foreign Corrupt Practices Act, theU.K. Bribery Act and other similar statutory requirements prohibiting bribery and corruption in the jurisdictions in which we operate. Governmental andhighly regulated entities often require contract terms that differ from our standard arrangements. For example, the federal government provides grants tocertain state and local governments for our applications and if such governmental entities do not continue to receive these grants, they have the ability toterminate their contracts without penalty. Governmental and highly regulated entities impose compliance requirements that are complicated, requirepreferential pricing or “most favored nation” terms and conditions, or are otherwise time consuming and expensive to satisfy. If we undertake to meet specialstandards or requirements and do not meet them, we could be subject to increased liability from our customers or regulators. Even if we do meet these specialstandards or requirements, the additional costs associated with providing our applications to government and highly regulated customers could harm ourmargins. Moreover, changes in the underlying regulatory conditions that affect these types of customers could harm our ability to efficiently provide ourapplications to them and to grow or maintain our customer base.Governmental demand and payment for our applications may also be impacted by public sector budgetary cycles and funding authorizations, with fundingreductions or delays adversely affecting public sector demand for our solutions.We are subject to governmental regulation and other legal obligations, particularly related to privacy, data protection and information security, and ouractual or perceived failure to comply with such obligations could harm our business. Compliance with such laws could also impair our efforts to maintainand expand our customer base, and thereby decrease our revenue.Our handling and storage of data is subject to a variety of laws and regulations, including regulation by various government agencies, including the U.S.Federal Trade Commission, or FTC, and various state, local and foreign agencies. We collect personally identifiable information and other data directly fromour customers and through our channel partners. We also process or otherwise handle personally identifiable information about our customers’ employees,customers and constituents in certain circumstances. We use this information to provide applications to our customers and to support, expand and improveour business. We may also share customers’ personally identifiable information with third parties as described in our privacy policy and/or as otherwiseauthorized by our customers.39 The U.S. federal and various state and foreign governments have adopted or proposed legislation that regulates the collection, distribution, use and storage ofpersonal information of individuals and that mandates security requirements with respect to certain personally identifiable information. In the United States,the FTC and numerous state attorneys general are imposing standards for the online collection, distribution, use and storage of data by applying federal andstate consumer protection laws. The lack of a clear and universal standard for protecting such information means, however, that these obligations may beinterpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other requirements or our practices. Any failureor perceived failure by us to comply with privacy or security laws, policies, legal obligations or industry standards or any security incident that results in theunauthorized release or transfer of sensitive corporate information, personally identifiable information or other customer data may result in governmentalenforcement actions, litigation, fines and penalties and/or adverse publicity, and could cause our customers to lose trust in us, which could have an adverseeffect on our reputation and business.Some proposed laws or regulations concerning privacy, data protection and information security are in their early stages, and we cannot yet determine howthese laws and regulations may be interpreted nor can we determine the impact these proposed laws and regulations, may have on our business. Suchproposed laws and regulations may require companies to implement privacy and security policies, permit users to access, correct and delete personalinformation stored or maintained by such companies, inform individuals of security breaches that affect their personal information, and, in some cases, obtainindividuals’ consent to use personal information for certain purposes. In addition, a foreign government could require that any personal information collectedin a country not be disseminated outside of that country, and we may not be currently equipped to comply with such a requirement. Our failure to complywith federal, state and international data privacy laws and regulators could harm our ability to successfully operate our business and pursue our businessgoals.In addition, several foreign countries and governmental bodies, including the European Union and Canada, have regulations governing the collection anduse of personal information obtained from their residents, which are often more restrictive than those in the United States. Laws and regulations in thesejurisdictions apply broadly to the collection, use, storage, disclosure and security of personal information that identifies or may be used to identify anindividual, such as names, email addresses and in some jurisdictions, Internet Protocol, or IP, addresses. Such regulations and laws may be modified and newlaws may be enacted in the future. Within the European Union, legislators recently adopted the General Data Protection Regulation, or GDPR, which, wheneffective in May 2018 will replace the 1995 European Union Data Protection Directive and supersede applicable European Union member state legislation.The GDPR includes more stringent operational requirements for processors and controllers of personal data and imposes significant penalties for non-compliance. If our privacy or data security measures fail to comply with current or future laws and regulations, we may be subject to litigation, regulatoryinvestigations, fines or other liabilities, as well as negative publicity and a potential loss of business. Moreover, if future laws and regulations limit ourcustomers’ ability to use and share personal information or our ability to store, process and share personal information, demand for our applications coulddecrease, our costs could increase, and our business, results of operations and financial condition could be harmed.New interpretations of existing laws, regulations or standards could require us to incur additional compliance costs and could restrict our business operations,and any failure by us to comply with applicable requirements may result in governmental enforcement actions, litigation, fines and penalties or adversepublicity, which could have an adverse effect on our reputation and business.Potential regulatory requirements placed on our applications and content could impose increased costs on us, delay or prevent our introduction of newapplications, and impair the function or value of our existing applications.Certain of our existing applications, such as CareConverge, a tailored version of our Secure Messaging application that is designed to comply with HIPAA,are and are likely to continue to be subject to increasing regulatory requirements in a number of ways and as we continue to introduce new applications, wemay be subject to additional regulatory requirements and other risks that could be costly and difficult to comply with or that could harm our business. Inaddition, we market our applications and professional services in certain countries outside of the United States and plan to expand our local presence inregions such as Europe, the Middle East and Asia. If additional legal and/or regulatory requirements are implemented in the foreign countries in which weprovide our services, the cost40 of developing or selling our applications may increase. As these requirements proliferate and as existing legal requirements become subject to newinterpretations, we must change or adapt our applications and professional services to comply. Changing regulatory requirements might render certain of ourapplications obsolete or might block us from accomplishing our work or from developing new applications. This might in turn impose additional costs uponus to comply or to further develop our applications. It might also make introduction of new applications or service types more costly or more time-consumingthan we currently anticipate. It might even prevent introduction by us of new applications or cause the continuation of our existing applications orprofessional services to become unprofitable or impossible.Risks Related to Ownership of Our Common StockOur stock price may be volatile and you may lose some or all of your investment.The market price of our common stock may be highly volatile and may fluctuate substantially as a result of a variety of factors, some of which are related incomplex ways. Since shares of our common stock were sold in our initial public offering, or IPO, in September 2016 at a price of $12.00 per share, our stockprice has ranged from an intraday low of $11.76 to an intraday high of $20.66 through December 31, 2016. Factors that may affect the market price of ourcommon stock include: •actual or anticipated fluctuations in our financial condition and operating results; •variance in our financial performance from expectations of securities analysts; •changes in the prices of our applications; •changes in our projected operating and financial results; •changes in laws or regulations applicable to our platform and applications; •announcements by us or our competitors of significant business developments, acquisitions or new applications; •our involvement in any litigation; •our sale of our common stock or other securities in the future; •changes in senior management or key personnel; •trading volume of our common stock; •changes in the anticipated future size and growth rate of our market; and •general economic, regulatory and market conditions.Recently, the stock markets have experienced extreme price and volume fluctuations that have affected and continue to affect the market prices of equitysecurities of many companies. These fluctuations have often been unrelated or disproportionate to the operating performance of those companies. Broadmarket and industry fluctuations, as well as general economic, political, regulatory and market conditions, may negatively impact the market price of ourcommon stock. In the past, companies that have experienced volatility in the market price of their securities have been subject to securities class actionlitigation. We may be the target of this type of litigation in the future, which could result in substantial costs and divert our management’s attention.An active public trading market for our common stock may not be sustained.Prior to the completion of our IPO in September 2016, no public market for our common stock existed. Although our common stock is listed on the NASDAQGlobal Market, we cannot assure you that an active public trading market for our common stock will continue to develop or be sustained. If an active marketfor our common stock does not continue to develop or is not sustained, it may be difficult for investors in our common stock to sell shares without depressingthe market price for the shares or to sell the shares at all. An inactive market may also impair our ability to raise capital to continue to fund operations byselling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.41 We are an emerging growth company, and we cannot be certain if the reduced reporting requirements applicable to emerging growth companies will makeour common stock less attractive to investors.We are an emerging growth company, as defined in the Jumpstart Our Business Startups Act, or the JOBS Act, enacted in April 2012. For as long as wecontinue to be an emerging growth company, we may take advantage of exemptions from various reporting requirements that are applicable to other publiccompanies that are not emerging growth companies, including not being required to comply with the auditor attestation requirements of Section 404 of theSarbanes-Oxley Act of 2002, as amended, or the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodicreports and proxy statements and exemptions from the requirements of holding nonbinding advisory votes on executive compensation and stockholderapproval of any golden parachute payments not previously approved. We will remain an emerging growth company until the earlier of (1) the last day of thefiscal year (a) following the fifth anniversary of the completion of the IPO, (b) in which we have total annual gross revenue of at least $1 billion or (c) inwhich we are deemed to be a large accelerated filer, which requires the market value of our common stock that is held by non-affiliates to exceed $700million as of the prior June 30th, and (2) the date on which we have issued more than $1 billion in non-convertible debt during the prior three-year period.We cannot predict if investors will find our common stock less attractive because we may rely on these exemptions. If some investors find our common stockless attractive as a result, there may be a less active trading market for our common stock and our stock price may be more volatile.As a result of becoming a public company, we are obligated to develop and maintain a system of effective internal control over financial reporting. Wemay not complete our analysis of our internal control over financial reporting in a timely manner, or these internal controls may not be determined to beeffective, which may harm investor confidence in our company and, as a result, the value of our common stock.We will be required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of ourinternal control over financial reporting in the second annual report we file with the U.S. Securities and Exchange Commission, or SEC. This assessment willneed to include disclosure of any material weaknesses identified by our management in our internal control over financial reporting. However, our auditorswill not be required to formally attest to the effectiveness of our internal control over financial reporting pursuant to Section 404 until we are no longer an“emerging growth company” as defined in the JOBS Act if we take advantage of the exemptions available to us through the JOBS Act.We are in the very early stages of the costly and challenging process of compiling the system and process documentation necessary to perform the evaluationneeded to comply with Section 404. In this regard, we will need to continue to dedicate internal resources, engage outside consultants and adopt a detailedwork plan to assess and document the adequacy of internal control over financial reporting, continue steps to improve control processes as appropriate,validate through testing that controls are functioning as documented and implement a continuous reporting and improvement process for internal controlover financial reporting. As we transition to the requirements of reporting as a public company, we may need to add additional finance staff. We may not beable to remediate any future material weaknesses, or to complete our evaluation, testing and any required remediation in a timely fashion. During theevaluation and testing process, if we identify one or more material weaknesses in our internal control over financial reporting, we will be unable to assert thatour internal controls are effective. If we are unable to assert that our internal control over financial reporting is effective, or if our auditors are unable toexpress an opinion on the effectiveness of our internal controls when they are required to issue such opinion, investors could lose confidence in the accuracyand completeness of our financial reports, the market price of our common stock could decline, and we could be subject to sanctions or investigations by theNASDAQ Stock Market, the SEC or other regulatory authorities. Failure to remedy any material weakness in our internal control over financial reporting, orto implement or maintain other effective control systems required of public companies, could also restrict our future access to the capital markets.42 If securities or industry analysts do not publish research or reports about our business, or if they issue an adverse or misleading opinion regarding ourstock, our stock price and trading volume could decline.The trading market for our common stock will be influenced by the research and reports that industry or securities analysts publish about us or our business.We do not have any control over these analysts. If any of the analysts who cover us issue an adverse or misleading opinion regarding us, our business model,our intellectual property or our stock performance, or if operating results fail to meet the expectations of analysts, our stock price would likely decline. If oneor more of these analysts cease coverage of us or fail to publish reports on us regularly, we could lose visibility in the financial markets, which in turn couldcause our stock price or trading volume to decline.We will incur increased costs as a result of operating as a public company and our management will be required to devote substantial time to newcompliance initiatives and corporate governance practices.As a public company, and particularly after we are no longer an “emerging growth company,” we will incur significant legal, accounting and other expensesthat we did not incur as a private company. The Sarbanes-Oxley Act, the Dodd-Frank Wall Street Reform and Consumer Protection Act, the listingrequirements of the NASDAQ Stock Market and other applicable securities rules and regulations impose various requirements on public companies. Ourmanagement and other personnel will need to devote a substantial amount of time to compliance with these requirements. Moreover, these rules andregulations will increase our legal and financial compliance costs and will make some activities more time-consuming and costly. We cannot predict orestimate the amount of additional costs we will incur as a public company or the timing of such costs. Such additional costs going forward could negativelyaffect our financial results.We do not anticipate paying any cash dividends in the foreseeable future, and accordingly, stockholders must rely on stock appreciation for any return ontheir investment.We have never declared or paid any cash dividends on our common stock and do not intend to pay any cash dividends to holders of our common stock in theforeseeable future. In addition, our ability to pay cash dividends is currently prohibited by the terms of our existing credit agreement and may be prohibitedby future credit agreements. As a result, capital appreciation, if any, of our common stock will be your sole source of gain for the foreseeable future.Our executive officers, directors and principal stockholders own a significant percentage of our stock and will be able to exert significant control overmatters subject to stockholder approval.Our directors, executive officers and holders of more than 5% of our common stock, some of whom are represented on our board of directors, together withtheir affiliates beneficially own approximately 47% of the voting power of our outstanding capital stock. As a result, these stockholders will be able to exertsignificant control over the outcome of matters submitted to our stockholders for approval. This ownership could affect the value of your shares of commonstock by, for example, these stockholders electing to delay, defer or prevent a change in corporate control, merger, consolidation, takeover or other businesscombination. This concentration of ownership may also adversely affect the market price of our common stock.We may invest or spend the proceeds of the IPO in ways with which you may not agree or in ways which may not yield a return.We anticipate that the remaining net proceeds from our IPO will be used for general corporate purposes, including working capital. We may also use a portionof the net proceeds to acquire complementary businesses, applications, services or technologies. However, we do not have any agreements or commitmentsfor any acquisitions at this time. Our management will have considerable discretion in the application of the net proceeds, and you will not have theopportunity to assess whether the proceeds are being used appropriately. The net proceeds may be invested with a view towards long-term benefits for ourstockholders and this may not increase our operating results or market value. The failure by our management to apply these funds effectively may adverselyaffect the return on your investment.43 Anti-takeover provisions in our charter documents and under Delaware law could make an acquisition of us more difficult, limit attempts by ourstockholders to replace or remove our current management and limit the market price of our common stock.Provisions in our amended and restated certificate of incorporation and our amended and restated bylaws may have the effect of delaying or preventing achange in control or changes in our management. Our amended and restated certificate of incorporation and amended and restated bylaws include provisionsthat: •authorize our board of directors to issue preferred stock, without further stockholder action and with voting liquidation, dividend and otherrights superior to our common stock; •require that any action to be taken by our stockholders be effected at a duly called annual or special meeting and not by written consent, andlimit the ability of our stockholders to call special meetings; •establish an advance notice procedure for stockholder proposals to be brought before an annual meeting, including proposed nominations ofpersons for director nominees; •establish that our board of directors is divided into three classes, with directors in each class serving three-year staggered terms; •require the approval of holders of two-thirds of the shares entitled to vote at an election of directors to adopt, amend or repeal our bylaws oramend or repeal the provisions of our certificate of incorporation regarding the election and removal of directors and the ability ofstockholders to take action by written consent or call a special meeting; •prohibit cumulative voting in the election of directors; and •provide that vacancies on our board of directors may be filled only by the vote of a majority of directors then in office, even though less thana quorum.These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult forstockholders to replace members of our board of directors, which is responsible for appointing the members of our management. In addition, because we areincorporated in Delaware, we are governed by the provisions of Section 203 of the General Corporation Law of the State of Delaware, which generallyprohibits a Delaware corporation from engaging in any of a broad range of business combinations with any “interested” stockholder for a period of threeyears following the date on which the stockholder became an “interested” stockholder. Any of the foregoing provisions could limit the price that investorsmight be willing to pay in the future for shares of our common stock, and they could deter potential acquirers of our company, thereby reducing thelikelihood that you would receive a premium for your common stock in an acquisition.Our amended and restated certificate of incorporation designates the Court of Chancery of the State of Delaware as the exclusive forum for certainlitigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us.Pursuant to our amended and restated certificate of incorporation, unless we consent in writing to the selection of an alternative forum, the Court of Chanceryof the State of Delaware is the sole and exclusive forum for (1) any derivative action or proceeding brought on our behalf, (2) any action asserting a claim ofbreach of a fiduciary duty owed by any of our directors, officers or other employees to us or our stockholders, (3) any action asserting a claim arising pursuantto any provision of the Delaware General Corporation Law, our amended and restated certificate of incorporation or our amended and restated bylaws or(4) any action asserting a claim governed by the internal affairs doctrine. Our amended and restated certificate of incorporation further provides that anyperson or entity purchasing or otherwise acquiring any interest in shares of our common stock is deemed to have notice of and consented to the foregoingprovision. The forum selection clause in our amended and restated certificate of incorporation may limit our stockholders’ ability to obtain a favorablejudicial forum for disputes with us.44 Future sales of our common stock in the public market could cause our share price to decline.Sales of a substantial number of shares of our common stock in the public market, or the perception that these sales might occur, could depress the marketprice of our common stock and could impair our ability to raise capital through the sale of additional equity securities. We are unable to predict the effectthat sales, particularly sales by our directors, executive officers and significant stockholders, may have on the prevailing market price of our common stock.Additionally, the shares of common stock subject to outstanding options under our equity incentive plans and the shares reserved for future issuance underour equity incentive plans, as well as shares issuable upon vesting of restricted stock awards, will become eligible for sale in the public market in the future,subject to certain legal and contractual limitations.Additionally, certain holders of our common stock have the right, subject to various conditions and limitations, to request we include their shares of ourcommon stock in registration statements we may file relating to our securities.In addition, in the future, we may issue common stock or other securities if we need to raise additional capital. The number of new shares of our commonstock issued in connection with raising additional capital could constitute a material portion of our then-outstanding shares of our common stock.Item 1B. Unresolved Staff Comments.NoneItem 2. Properties.Our principal executive offices are located in Burlington, Massachusetts, where we occupy an approximately 45,000 square-foot facility under a leaseexpiring on May 31, 2022, and in Pasadena, California, where we occupy an approximately 19,000 square-foot facility under a lease expiring on June 30,2018. We also have offices in San Francisco, California; Windsor, United Kingdom; Colchester, United Kingdom; Beijing, China; and Norsburg, Sweden.We believe that our current facilities are suitable and adequate to meet our current needs. We intend to add new facilities or expand existing facilities as weadd employees, and we believe that suitable additional or substitute space will be available as needed to accommodate any such expansion of our operations.Item 3. Legal Proceedings.From time to time we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently aparty to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business,operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlementcosts, diversion of management resources and other factors.Item 4. Mine Safety Disclosures.Not applicable45 PART IIItem 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities.Market InformationOur common stock, has been listed on The NASDAQ Global Market under the symbol “EVBG” since September 16, 2016. Prior to that date, there was nopublic trading market for our common stock.The following table sets forth the reported high and low sales prices of our common stock for the periods indicated, as quoted on The NASDAQ GlobalMarket: High Low Third Quarter (from September 16, 2016 to September 30, 2016) $18.73 $11.76 Fourth Quarter $20.66 $12.92 As of December 31, 2016, there were 525 holders of record of our common stock. Because many of our shares are held by brokers and other institutions onbehalf of stockholders, we are unable to estimate the total number of stockholders represented by these record holders.DividendsWe have never declared or paid, and do not anticipate declaring or paying in the foreseeable future, any cash dividends on our common stock. Any futuredetermination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors, subject to applicable laws, and willdepend on then existing conditions, including our financial condition, operating results, contractual restrictions, capital requirements, business prospects,and other factors our board of directors may deem relevant.Stock Performance GraphThe following shall not be deemed incorporated by reference into any of our other filings under the Securities Exchange Act of 1934, as amended, or theSecurities Act of 1933, as amended, except to the extent we specifically incorporate it by reference into such filings.The following graph shows a comparison from September 16, 2016 (the date our common stock commenced trading on The NASDAQ Global Market)through December 31, 2016 of the cumulative total return for an investment of $100 in our common stock, the S&P 500 Stock Index and the S&P 500Information Technology Index.

As of December 31, 2016, ourcustomers were based in 28 countries and included eight of the 10 largest U.S. cities, eight of the 10 largest U.S.-based investment banks, 24 of the 25 busiestNorth American airports, six of the 10 largest global consulting firms, six of the 10 largest global auto makers, all four of the largest global accounting firms,four of the 10 largest U.S.-based health care providers and four of the 10 largest U.S.-based health insurers. We provide our applications to customers ofvarying sizes, including enterprises, small businesses, non-profit organizations, educational institutions and governmental agencies. Our customers span awide variety of industries including technology, energy, financial services, healthcare and life sciences, manufacturing, media and entertainment, retail,higher education and professional services.We sell all of our critical communications applications on a subscription basis. We generally enter into contracts that range from one to three years in length,with an average contract duration of 2.0 years as of December 31, 2016, and generally bill and collect payment annually in advance. We derive most of ourrevenue from subscriptions to applications. Over 90% of the revenue that we recognized in each of the eight most recently completed quarters was generatedfrom contracts entered into in prior quarters or renewals of those contracts; the balance of the revenue that we recognized in each such quarter was generatedfrom contracts entered into with new customers or new contracts, other than renewals, entered into with existing customers in such quarter. Historically, wederived more than 86% of our revenue in each of the last three fiscal years from sales of our Mass Notification application. Our pricing model is based on thenumber of applications subscribed to and, per application, the number of people, locations and things connected to our platform as well as the volume ofcommunications. We also offer premium services including data feeds for social media, threat intelligence and weather. We generate additional revenue byexpanding the number of applications that our customers subscribe to and the number of contacts and devices connected to our platform.50 We generated revenue of $76.8 million in 2016, $58.7 million in 2015, $42.4 million in 2014 and $30.0 million in 2013, representing year-over-yearincreases of 41% in 2014, 38% in 2015 and 31% in 2016. We had net losses of $11.3 million, $10.8 million, $0.6 million and $0.9 million in 2016, 2015,2014 and 2013, respectively.As of December 31, 2016 and 2015, 14% and 17% of our customers, respectively, were located outside of the United States and these customers generated10% and 14% of our total revenue for the years ended December 31, 2016 and 2015, respectively.We have focused on rapidly growing our business and believe that the future growth of our business is dependent on many factors, including our ability toincrease the functionality of our platform and applications, expand our customer base, accelerate adoption of our applications beyond Mass Notificationwithin our existing customer base and expand our international presence. Our future growth will also depend on the growth in the market for criticalcommunications solutions and our ability to effectively compete. In order to further penetrate the market for critical communications solutions and capitalizeon what we believe to be a significant opportunity, we intend to continue to invest in research and development, build-out our data center infrastructure andservices capabilities and hire additional sales representatives, both domestically and internationally, to drive sales to new customers and incremental sales ofnew applications to existing customers. Nevertheless, we expect to continue to incur losses in the near term and, if we are unable to achieve our growthobjectives, we may not be able to achieve profitability.Recent DevelopmentsIn September 2016, we closed our initial public offering, or IPO, at which time we sold a total of 6,250,000 shares of our common stock. We received net cashproceeds of $66.1 million, net of underwriting discounts and commissions and other costs associated with the offering paid or payable by us.In December 2016, we acquired 100% of the shares of Svensk Krisledning AB, or Crisis Commander. We acquired Crisis Commander for cash considerationof approximately $2.3 million with additional time and performance-based milestones that could result in additional payments of $0.4 million. CrisisCommander is a SaaS mobile crisis management company operating out of Sweden.In January 2017, we acquired 100% of the shares of IDV Solutions, LLC, or IDV. We acquired IDV for cash consideration of approximately $21.3 million,with additional time and performance-based milestones that could result in additional payments of $6.2 million. IDV is a provider of threat assessment andoperational visualization software located in Lansing, Michigan.Presentation of Financial StatementsOur consolidated financial statements include the accounts of our wholly-owned subsidiaries. Business acquisitions are included in our consolidatedfinancial statements from the date of the acquisition. Our purchase accounting resulted in all assets and liabilities of acquired businesses being recorded attheir estimated fair values on the acquisition dates. All intercompany balances and transactions have been eliminated in consolidation.We report our financial results as one operating segment. Our operating results are regularly reviewed on a consolidated basis by our chief executive officer,who is our chief operating decision maker, principally to make strategic decisions regarding how we allocate our resources and to assess our consolidatedoperating performance.51 Other MetricsWe regularly monitor a number of financial and operating metrics in order to measure our current performance and estimate our future performance. Our otherbusiness metrics may be calculated in a manner different than similar other business metrics used by other companies. Year Ended December 31, 2016 2015 2014 (dollars in thousands) Revenue retention rate 116% 112% 111%Adjusted EBITDA $5 $(3,351) $2,524 Adjusted gross margin $55,577 $41,084 $30,663 Free cash flow $3,039 $(2,953) $3,884 •Revenue Retention Rate. We calculate our revenue retention rate by dividing (1) total revenue in the current 12-month period from thosecustomers who were customers during the prior 12-month period by (2) total revenue from all customers in the prior 12-month period. For thepurposes of calculating our revenue retention rate, we count as customers all entities with whom we had contracts in the applicable periodother than (1) customers of our wholly-owned subsidiary, Microtech, which generates an immaterial amount of our revenue in any given yearand (2) in the first year following our acquisition of another business, customers that we acquired in connection with such acquisition. Webelieve that our ability to retain our customers and expand their use of our solutions over time is an indicator of the stability of our revenuebase and the long-term value of our customer relationships. Our revenue retention rate provides insight into the impact on current periodrevenue of the number of new customers acquired during the prior 12-month period, the timing of our implementation of those newcustomers, growth in the usage of our solutions by our existing customers and customer attrition. If our revenue retention rate for a periodexceeds 100%, this means that the revenue retained during the period including upsells more than offset the revenue that we lost fromcustomers that did not renew their contracts during the period. Our revenue retention rate may decline or fluctuate as a result of a number offactors, including customers’ satisfaction or dissatisfaction with our platform and applications, pricing, economic conditions or overallreductions in our customers’ spending levels. •Adjusted EBITDA. Adjusted EBITDA represents our net loss before interest income and interest expense, income tax expense and benefit,depreciation and amortization expense and stock-based compensation expense. We do not consider these items to be indicative of our coreoperating performance. The items that are non-cash include depreciation and amortization expense and stock-based compensation expense.Adjusted EBITDA is a measure used by management to understand and evaluate our core operating performance and trends and to generatefuture operating plans, make strategic decisions regarding the allocation of capital and invest in initiatives that are focused on cultivatingnew markets for our solutions. In particular, the exclusion of certain expenses in calculating adjusted EBITDA facilitates comparisons of ouroperating performance on a period-to-period basis. Adjusted EBITDA is not a measure calculated in accordance with GAAP. We believe thatadjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the samemanner as our management and board of directors. Nevertheless, use of adjusted EBITDA has limitations as an analytical tool, and youshould not consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. Some of these limitationsare: (1) although depreciation and amortization are non-cash charges, the capitalized software that is amortized will need to be replaced inthe future, and adjusted EBITDA does not reflect cash capital expenditure requirements for such replacements or for new capital expenditurerequirements; (2) adjusted EBITDA does not reflect changes in, or cash requirements for, our working capital needs; (3) adjusted EBITDAdoes not reflect the potentially dilutive impact of equity-based compensation; (4) adjusted EBITDA does not reflect tax payments or receiptsthat may represent a reduction or increase in cash available to us; and (5) other companies, including companies in our industry, maycalculate adjusted EBITDA or similarly titled measures differently, which reduces the usefulness of the metric as a comparative measure.Because of these and other limitations, you should consider adjusted EBITDA alongside our other GAAP-based financial performancemeasures, net loss and our other GAAP financial results. The following table presents a reconciliation of adjusted EBITDA to net loss, themost directly comparable GAAP measure, for each of the periods indicated:52 Year Ended December 31, 2016 2015 2014 (in thousands) Net loss $(11,286) $(10,824) $(623)Interest expense, net 472 537 348 Benefit from income taxes (24) (562) (89)Depreciation and amortization 7,742 5,976 2,512 Stock-based compensation 3,101 1,522 376 Adjusted EBITDA $5 $(3,351) $2,524 •Adjusted Gross Margin. Adjusted gross margin represents gross profit plus stock-based compensation and amortization of acquiredintangibles. Adjusted gross margin is a measure used by management to understand and evaluate our core operating performance and trendsand to generate future operating plans. The exclusion of stock-based compensation expense and amortization of acquired intangiblesfacilitates comparisons of our operating performance on a period-to-period basis. In the near term, we expect these expenses to continue tonegatively impact our gross profit. Adjusted gross margin is not a measure calculated in accordance with GAAP. We believe that adjustedgross margin provides useful information to investors and others in understanding and evaluating our operating results in the same manner asour management and board of directors. Nevertheless, our use of adjusted gross margin has limitations as an analytical tool, and you shouldnot consider it in isolation or as a substitute for analysis of our financial results as reported under GAAP. You should consider adjusted grossmargin alongside our other GAAP-based financial performance measures, gross profit and our other GAAP financial results. The followingtable presents a reconciliation of adjusted gross margin to gross profit, the most directly comparable GAAP measure, for each of the periodsindicated: Year Ended December 31, 2016 2015 2014 (in thousands) Gross profit $53,079 $38,931 $30,332 Amortization of acquired intangibles 2,318 2,003 249 Stock-based compensation 180 150 82 Adjusted gross margin $55,577 $41,084 $30,663 •Free Cash Flow. Free cash flow represents net cash provided by operating activities minus capital expenditures and capitalized softwaredevelopment costs. Free cash flow is a measure used by management to understand and evaluate our core operating performance and trendsand to generate future operating plans. The exclusion of capital expenditures and amounts capitalized for internally-developed softwarefacilitates comparisons of our operating performance on a period-to-period basis and excludes items that we do not consider to be indicativeof our core operating performance. Free cash flow is not a measure calculated in accordance with GAAP. We believe that free cash flowprovides useful information to investors and others in understanding and evaluating our operating results in the same manner as ourmanagement and board of directors. Nevertheless, our use of free cash flow has limitations as an analytical tool, and you should not considerit in isolation or as a substitute for analysis of our financial results as reported under GAAP. You should consider free cash flow alongside ourother GAAP-based financial performance measures, net cash provided by operating activities, and our other GAAP financial results. Thefollowing table presents a reconciliation of free cash flow to net cash for operating activities, the most directly comparable GAAP measure,for each of the periods indicated: Year Ended December 31, 2016 2015 2014 (in thousands) Net cash provided by operating activities $9,503 $4,451 $7,716 Capital expenditures (970) (2,502) (2,155)Capitalized software development costs (5,494) (4,902) (1,677)Free cash flow $3,039 $(2,953) $3,884 53 Additional Supplemental Non-GAAP Financial MeasuresTo supplement our consolidated financial statements, which are prepared and presented in accordance with GAAP, we provide investors with certainadditional supplemental non-GAAP financial measures, including non-GAAP cost of revenue, non-GAAP gross profit, non-GAAP sales and marketingexpense, non-GAAP research and development expense, non-GAAP general and administrative expense, non-GAAP total operating expenses, non-GAAPoperating loss and non-GAAP net loss, which we collectively refer to as non-GAAP financial measures. These non-GAAP financial measures exclude all or acombination of the following (as reflected in the following reconciliation tables): stock-based compensation expense and amortization of acquiredintangibles. The presentation of the non-GAAP financial measures is not intended to be considered in isolation or as a substitute for, or superior to, thefinancial information prepared and presented in accordance with GAAP. We use these non-GAAP financial measures for financial and operational decision-making purposes and as a means to evaluate period-to-period comparisons. We believe that these non-GAAP financial measures provide useful informationabout our operating results, enhance the overall understanding of past financial performance and future prospects and allow for greater transparency withrespect to metrics used by our management in its financial and operational decision making. While our non-GAAP financial measures are an important toolfor financial and operational decision making and for evaluating our own operating results over different periods of time, you should consider our non-GAAPfinancial measures alongside our GAAP financial results.We exclude stock-based compensation expense because of varying available valuation methodologies, subjective assumptions and the variety of equityinstruments that can impact our non-cash expense. We believe that providing non-GAAP financial measures that exclude stock-based compensation expenseallow for more meaningful comparisons between our operating results from period to period. We believe that excluding the impact of amortization ofacquired intangibles allows for more meaningful comparisons between operating results from period to period as the intangibles are valued at the time ofacquisition and are amortized over a period of several years after the acquisition. Accordingly, we believe that excluding these expenses provides investorsand management with greater visibility of the underlying performance of our business operations, facilitates comparison of our results with other periods andmay also facilitate comparison with the results of other companies in our industry.There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP, may bedifferent from non-GAAP financial measures used by other companies and exclude expenses that may have a material impact upon our reported financialresults. Further, stock-based compensation expense has been and will continue to be for the foreseeable future a significant recurring expense in our businessand an important part of the compensation provided to our employees.54 The following table reconciles our GAAP to non-GAAP financial measures for the years ended 2016, 2015 and 2014: Year Ended December 31, 2016 2015 2014 (dollars in thousands) Cost of revenue $23,767 $19,789 $12,089 Amortization of acquired intangibles (2,318) (2,003) (249)Stock-based compensation expense (180) (150) (82)Non-GAAP cost of revenue 21,269 17,636 11,758 Gross profit 53,079 38,931 30,332 Amortization of acquired intangibles 2,318 2,003 249 Stock-based compensation expense 180 150 82 Non-GAAP gross profit 55,577 41,084 30,663 Non-GAAP gross margin 72.32% 69.97% 72.28% Sales and marketing expense 34,847 25,925 15,818 Stock-based compensation expense (725) (315) (120)Non-GAAP sales and marketing 34,122 25,610 15,698 Research and development expense 14,765 11,521 7,365 Stock-based compensation expense (348) (297) (147)Non-GAAP research and development 14,417 11,224 7,218 General and administrative expense 14,293 12,272 7,435 Amortization of acquired intangibles (916) (1,088) (720)Stock-based compensation expense (1,848) (760) (27)Non-GAAP general and administrative 11,529 10,424 6,688 Total operating expenses 63,905 49,718 30,618 Amortization of acquired intangibles (916) (1,088) (720)Stock-based compensation expense (2,921) (1,372) (294)Non-GAAP total operating expenses $60,068 $47,258 $29,604 Operating loss $(10,826) $(10,787) $(286)Amortization of acquired intangibles 3,234 3,091 969 Stock-based compensation expense 3,101 1,522 376 Non-GAAP operating income (loss) $(4,491) $(6,174) $1,059 Net loss $(11,286) $(10,824) $(623)Amortization of acquired intangibles 3,234 3,091 969 Stock-based compensation expense 3,101 1,522 376 Non-GAAP net income (loss) $(4,951) $(6,211) $722 Components of Results of OperationsRevenueWe derive substantially all of our revenue from the sale of subscriptions to our critical communications and enterprise safety applications.We generally bill and collect payment for our subscriptions annually in advance. All revenue billed in advance of services being delivered is recorded indeferred revenue. The initial subscription period typically ranges from one to three years. We offer varying levels of customer support based on customerneeds and the complexity of their businesses, including the level of usage by a customer in terms of minutes or the amount of data used to transmit thenotifications. Our pricing model is based on the number of applications subscribed to and, per application, the55 number of people, locations and things connected to our platform as well as the volume of communications. We also offer premium services including datafeeds for social media, threat intelligence and weather. We generate additional revenue by expanding the number of premium features and applications thatour customers subscribe to and the number of contacts connected to our platform.We generate an immaterial amount of revenue from set-up fees, which consist of participant process mapping, configuration, customer data migration andintegration. We also sell professional services, which have been immaterial to date.Cost of RevenueCost of revenue includes expenses related to the fulfillment of our subscription services, consisting primarily of employee-related expenses for data centeroperations and customer support, including salaries, bonuses, benefits and stock-based compensation expense. Cost of revenue also includes hosting costs,messaging costs and depreciation and amortization. As we add data center capacity and support personnel in advance of anticipated growth, our cost ofrevenue will increase and, if anticipated revenue growth does not occur, our gross profit will be adversely affected.Operating ExpensesOperating expenses consist of sales and marketing, research and development and general and administrative expenses. Salaries, bonuses, stock-basedcompensation expense and other personnel costs are the most significant components of each of these expense categories. We include stock-basedcompensation expense incurred in connection with the grant of stock options within the applicable operating expense category based on the equity awardrecipient’s functional area.Sales and MarketingSales and marketing expense primarily consists of employee-related expenses for sales, marketing and public relations employees, including salaries,bonuses, commissions, benefits and stock-based compensation expense. Sales and marketing expense also includes trade show, market research, advertisingand other related external marketing expense as well as office and software related costs to support sales. We defer certain sales commissions related toacquiring new customers and amortize these expenses ratably over the term of the corresponding subscription agreement. We plan to continue to expand oursales and marketing functions to grow our customer base and increase sales to existing customers. This growth will include adding sales personnel andexpanding our marketing activities to continue to generate additional leads and build brand awareness. In the near term, we expect our sales and marketingexpense to increase on an absolute dollar basis as we hire new sales representatives in the United States and worldwide and grow our marketing staff.Research and DevelopmentResearch and development expense primarily consists of employee-related expenses for research and development staff, including salaries, bonuses, benefitsand stock-based compensation expense. Research and development expense also includes the cost of certain third-party services, office related costs tosupport research and development activities, software subscriptions and hosting costs. We capitalize certain software development costs that are attributableto developing new applications and adding incremental functionality to our platform and amortize these costs over the estimated life of the new applicationor incremental functionality, which is generally three years. We focus our research and development efforts on improving our applications, developing newapplications and delivering new functionality. In the near term, we expect our research and development expense to increase on an absolute dollar basis as wecontinue to increase the functionality of our platform and applications.56 General and AdministrativeGeneral and administrative expense primarily consists of employee-related expenses for administrative, legal, finance and human resource personnel,including salaries, bonuses, benefits and stock-based compensation expense. General and administrative expense also includes professional fees, insurancepremiums, corporate expenses, transaction-related costs, office-related expenses, facility costs, depreciation and amortization and software license costs. Inthe near term, we expect our general and administrative expense to increase on an absolute dollar basis as we incur the costs associated with being a publiclytraded company.Interest IncomeInterest income consists of interest earned on our cash balances held at financial institutions.Interest ExpenseInterest expense consists of interest on our outstanding debt obligations and interest on our capital leases.Other Expenses, NetOther expenses, net consists primarily of realized foreign currency gains and losses.Results of OperationsThe following tables set forth our results of operations for the periods presented and as a percentage of our total revenue for those periods.

The remaining increase wasprincipally the result of a $2.8 million increase in depreciation and amortization expense attributable to our acquired intangible assets, a $1.8 millionincrease in hosting and messaging costs and a $0.3 million increase in office related expenses.Gross margin percentage decreased due to an increase in amortization of acquired intangible assets and capitalized software, as well as our continuedinvestment in personnel to support our growth.Operating ExpensesSales and Marketing Expense Year Ended December 31, Change 2015 2014 $ % (dollars in thousands) Sales and marketing $25,925 $15,818 $10,107 63.9%% of revenue 44% 37% Sales and marketing expense increased by $10.1 million in 2015 compared to 2014. The increase was primarily due to an $8.1 million increase in employee-related costs associated with our increased headcount from 104 employees as of December 31, 2014 to 157 employees as of December 31, 2015. Theremaining increase was principally the result of a $1.1 million increase in trade show and advertising costs and a $0.9 million increase in office related coststo support sales.Research and Development Expense Year Ended December 31, Change 2015 2014 $ % (dollars in thousands) Research and development $11,521 $7,365 $4,156 56.4%% of revenue 20% 17% Research and development expense increased by $4.2 million in 2015 compared to 2014. The increase was primarily due to a $6.5 million increase inemployee-related costs associated with our increased headcount from 83 employees as of December 31, 2014 to 109 employees as of December 31, 2015. Theremaining increase was principally the result of a $0.9 million increase in office and software related cost to support research and development activities. Atotal of $4.8 million of internally-developed software costs during 2015 and $1.6 million of internally-developed software costs during 2014 werecapitalized, resulting in a reduction of the expense by $3.2 million in 2015.General and Administrative Expense Year Ended December 31, Change 2015 2014 $ % (dollars in thousands) General and administrative $12,272 $7,435 $4,837 65.1%% of revenue 21% 18% 61 General and administrative expense increased by $4.8 million in 2015 compared to 2014. The increase was primarily due to a $2.5 million increase inemployee-related costs associated with our increased headcount from 44 employees as of December 31, 2014 to 62 employees as of December 31, 2015. Theremaining increase was the result of a $1.7 million increase in professional fees due to increased legal, accounting and audit services to support ouroperations and our preparations to become a public company, a $0.4 million increase in office related expenses and a $0.4 million increase in depreciationand amortization expense related to equipment. These increases were offset by a $0.2 million decrease in legal and transaction-related costs in 2015.Other Expense, Net Year Ended December 31, Change 2015 2014 $ % (dollars in thousands) Other expense, net $599 $426 $173 40.6%% of revenue 1% 1% Other expense, net increased by $0.2 million in 2015 compared to 2014 as a result of increased interest expense related to accretion of interest on our notespayable, interest expense due under our term loan and revolving line of credit.Income Taxes Year Ended December 31, Change 2015 2014 $ % (dollars in thousands) Benefit from income taxes $(562) $(89) $(473) 531.5%% of revenue 1% 0% Benefit from income taxes increased by $0.5 million in 2015 compared to 2014 due to our increased operations in foreign jurisdictions where we are subjectto income taxes on profits which have benefited from current losses.Liquidity and Capital ResourcesTo date, we have financed our operations primarily through cash from operating activities, along with equity issuances and debt financing arrangements. Ourprincipal source of liquidity is cash and cash equivalents totaling $60.8 million as of December 31, 2016, which includes the remaining net proceeds fromour initial public offering completed in September 2016. We received net proceeds of $66.1 million, after deducting underwriting discounts and offeringexpenses paid or payable by us. We have generated significant losses since inception and expect to continue to generate losses for the foreseeable future.We believe that our cash balances, our available borrowings under our revolving line of credit and the cash flows generated by our operations will besufficient to satisfy our anticipated cash needs for working capital and capital expenditures for at least the next 12 months. However, our belief may prove tobe incorrect, and we could utilize our available financial resources sooner than we currently expect. Our future capital requirements and the adequacy ofavailable funds will depend on many factors, including those set forth in the section of this Annual Report on Form 10-K titled “Risk Factors.” We cannotassure you that we will be able to raise additional capital on acceptable terms or at all. In addition, if we fail to meet our operating plan during the next 12months, our liquidity could be adversely affected.62 Cash FlowsThe following table shows a summary of our cash flows for the years ended December 31, 2016, 2015 and 2014: Year Ended December 31, 2016 2015 2014 (dollars in thousands) Cash and cash equivalents at beginning of period $8,578 $4,412 $3,040 Cash provided by operating activities 9,503 4,451 7,716 Cash used in investing activities (9,020) (7,404) (4,136)Cash provided by (used in) financing activities 51,470 7,219 (2,120)Effects of exchange rates on cash and cash equivalents 234 (100) (88)Cash and cash equivalents at end of period $60,765 $8,578 $4,412 At December 31, 2016, $1.5 million of the $60.8 million of cash and cash equivalents was held by foreign subsidiaries. Our intention is to indefinitelyreinvest foreign earnings in our foreign subsidiaries. If these earnings were used to fund domestic operations, they would be subject to additional incometaxes upon repatriation.Sources of Funds Initial Public OfferingOn September 21, 2016, we closed our initial public offering in which we issued and sold 6,250,000 shares of common stock at a public offering price of$12.00 per share for net proceeds of approximately $66.1 million, after deducting underwriting discounts and offering expenses paid or payable by us.Credit FacilityIn June 2015, we entered into a loan and security agreement with Western Alliance Bank (formerly known as Bridge Bank) to provide a secured revolvingline of credit that allows us to borrow up to $10.0 million for working capital and general business requirements. In February 2016, we entered into anamendment of our loan and security agreement with Western Alliance Bank to (1) increase the capacity of our revolving line of credit by $5.0 million to$15.0 million and (2) set the minimum prime rate based on which interest due is calculated at 3.25%. No other changes were made to the loan and securityagreement. The loan and security agreement, as amended, allows us to borrow up to $15.0 million for working capital and general business requirements.Amounts outstanding under the line of credit bear interest at the prime rate plus 0.75% with accrued interest payable on a monthly basis and outstanding andunpaid principal due upon maturity of the credit facility in June 2018. As of December 31, 2016, the total amount available to be borrowed by us was $15.0million and we had no outstanding balance on the revolving line of credit.Western Alliance Bank maintains a security interest in substantially all of our tangible and intangible assets, excluding intellectual property, to secure anyoutstanding amounts under the loan agreement. The loan agreement contains customary events of default, conditions to borrowing and covenants, includingrestrictions on our ability to dispose of assets, make acquisitions, incur debt, incur liens and make distributions and dividends to stockholders. The loanagreement also includes a financial covenant related to our recurring revenue renewal rate. During the continuance of an event of default, Western AllianceBank may accelerate amounts outstanding, terminate the credit facility and foreclose on the collateral.63 Uses of FundsOur historical uses of cash have primarily consisted of cash used for operating activities, such as expansion of our sales and marketing operations, researchand development activities and other working capital needs.Operating ActivitiesOur net loss and cash flows provided by operating activities are significantly influenced by our investments in headcount and infrastructure to support ourgrowth, marketing and sponsorship expenses, and our ability to bill and collect in a timely manner. Our net loss has been significantly greater than our use ofcash for operating activities due to the inclusion of non-cash expenses and charges.Operating activities provided $9.5 million in 2016, primarily from $9.6 million in cash provided as a result of changes in operating assets and liabilities,which was increased by $11.2 million of non-cash operating expenses and partially offset by our net loss of $11.3 million. Specifically, we recognized non-cash charges aggregating $7.7 million for depreciation and amortization of intangible assets, capitalized software development costs and property andequipment, $3.1 million for stock-based compensation expense, $0.4 million for the increase in our accounts receivable provision and $0.1 million related tonon-cash interest on notes payable, offset by a $0.1 million decrease in our deferred income taxes. The change in operating assets and liabilities reflected a$12.0 million increase in deferred revenue, a $1.3 million increase in accrued employee-related expenses due to timing of payments, and a $0.5 millionincrease in accrued expenses due to timing of payments made to vendors. These increases were partially offset by a $2.3 million increase in accountsreceivable, a $1.1 million increase in other assets due to timing of payments made for deferred IPO cost and commissions, a $0.4 million decrease in accountspayable due to the timing of payments made and a $0.3 million increase in prepaid expenses as a result of the increase in upfront payments made forinsurance services.Operating activities provided $4.5 million in 2015, primarily from $7.7 million in cash provided as a result of changes in operating assets and liabilities,which was increased by $7.5 million of non-cash operating expenses and partially offset by our net loss of $10.8 million. Specifically, we recognized non-cash charges aggregating $6.0 million for depreciation and amortization of intangible assets, capitalized software development costs and property andequipment, $1.5 million for stock-based compensation expense, $0.4 million for the increase in our accounts receivable provision and $0.1 million related tonon-cash interest on notes payable, offset by a $0.4 million decrease in our deferred income taxes. The change in operating assets and liabilities reflected an$11.6 million increase in deferred revenue, a $1.2 million increase in accrued employee-related expenses due to timing of payments and a $0.9 millionincrease in accounts payable due to timing of payments made to vendors. These increases were partially offset by a $4.8 million increase in accountsreceivable, a $0.7 million increase in prepaid expenses as a result of the increase in upfront payments made for insurance services, a $0.4 million increase inother assets due to timing of payments made for deferred IPO cost and commissions and a $0.2 million decrease in accrued expenses due to the timing ofpayments made.Investing ActivitiesOur investing activities consist primarily of capital expenditures for capitalized software development costs and property and equipment purchases.Investing activities used $9.0 million in 2016, primarily from net cash paid in acquisitions of $2.3 million, and our investment in software development of$5.5 million and property and equipment of $1.0 million.Investing activities used $7.4 million in cash in 2015, primarily from our investment in software development of $4.9 million and property and equipment of$2.5 million.Financing ActivitiesCash generated by financing activities includes proceeds from our initial public offering, borrowings under our term loan and credit facilities and proceedsfrom the issuance of common stock upon the exercise of employee stock options. Cash used in financing activities includes deferred initial public offeringcosts and payments on capital leases, notes payable and repayments of debt under our credit facilities.64 Financing activities provided $51.5 million of cash in 2016, which reflects proceeds of $67.8 million from our initial public offering, net of underwriter’sdiscount and commissions, $0.8 million from the exercise of stock options and proceeds from our line of credit of $9.5 million. These amounts were offset bya $19.5 million payment on our line of credit, a $5.0 million payment on our term loan and a $2.0 million payment on notes payable related to the VocalLimited acquisition.Financing activities provided $7.2 million in cash in 2015, primarily from proceeds from our term loan of $5.0 million and proceeds from our line of credit of$12.0 million, partially offset by a $1.5 million payment to repurchase outstanding shares of our common stock, $5.0 million in payments on our line ofcredit, $1.8 million in payments on notes payable, $1.4 million in payments attributed to deferred initial public offering costs and $0.1 million in paymentson capital leases.Contractual Obligations and CommitmentsThe following table summarizes our commitments to settle contractual obligations as of December 31, 2016: Less than1 Year 1 to 3Years 3 to 5Years More than5 Years Total (in thousands) Operating Leases (1) $1,828 $3,514 $3,335 $705 $9,382 $1,828 $3,514 $3,335 $705 $9,382 (1)Operating leases include total future minimum rent payments under non-cancelable operating lease agreements as described in note (18) of ourconsolidated financial statements included in this Annual Report on Form 10-K.Future minimum operating lease payments have been reduced by future minimum sublease income of $0.2 million.In December 2016, we entered into a new lease for our executive offices in Burlington, Massachusetts that will increase our future minimum leasecommitments over the next five years by $8.0 million.The above table does not include any payments we may have to make under the contingent liability related to the Crisis Commander and IDV acquisitions,as the amount of the ultimate payments are unknown. Please see Note 5 and 19 of the notes to our consolidated financial statements for more information.The commitment amounts in the table above are associated with contracts that are enforceable and legally binding and that specify all significant terms,including fixed or minimum services to be used, fixed, minimum or variable price provisions and the approximate timing of the actions under the contracts.The table does not include obligations under agreements that we can cancel without a significant penalty.BacklogWe sell all of our critical communications applications on a subscription basis. We generally enter into contracts that range from one to three years in length,with an average contract duration of 2.0 years as of December 31, 2016, and generally bill and collect payment annually in advance. Since we bill many ofour customers at the beginning of each contract year, there can be amounts that we have not yet been contractually able to invoice. Until such time as theseamounts are invoiced, they are not recorded in revenue, deferred revenue or elsewhere in our consolidated financial statements. As of December 31, 2016, thedollar amount of this backlog believed to be firm was $39.3 million. We expect that the amount of backlog relative to the total value of our subscriptionagreements will change from year to year for several reasons, including the specific timing and duration of customer agreements, varying invoicing cycles ofagreements, the specific timing of customer renewals and changes in customer financial circumstances. In addition, because revenue for any period is afunction of revenue recognized from deferred revenue under contracts in existence at the beginning of the period, as well as contracts that are renewed andnew customer contracts that are entered into during the period, backlog at the beginning of any period is not necessarily indicative of future performance. Ourpresentation of backlog may also differ from that of other companies in our industry. Due to these factors, as well as variances in billing arrangements withcustomers, we do not utilize backlog as a key management metric internally.65 Off-Balance Sheet ArrangementsWe do not have any relationships with unconsolidated entities or financial partnerships, including entities sometimes referred to as structured finance orspecial purpose entities that were established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.We do not engage in off-balance sheet financing arrangements. In addition, we do not engage in trading activities involving non-exchange traded contracts.Critical Accounting PoliciesOur consolidated financial statements are prepared in accordance with GAAP. The preparation of our consolidated financial statements require us to makeestimates, assumptions and judgments that affect the reported amounts of revenue, assets, liabilities, costs and expenses. We base our estimates andassumptions on historical experience and other factors that we believe to be reasonable under the circumstances. We evaluate our estimates and assumptionson an ongoing basis. Our actual results may differ from these estimates. Our most critical accounting policies are summarized below.Revenue RecognitionWe derive substantially all of our revenue from contract subscription fees for use of our applications.We recognize revenue in accordance with ASC Topic 605, Revenue Recognition, with respect to a transaction when all of the following conditions have beensatisfied: •persuasive evidence of an agreement exists; •the service has been provided to the customer; •fees are fixed or determinable; and •the collection of the fees is reasonably assured and acceptance criteria, if any, have been met.If any of these criteria are not met, revenue recognition is deferred until such time that all of the criteria are met.Our subscription arrangements do not provide customers with the right to take possession of our software at any time.Subscription RevenueWe recognize subscription revenue ratably over the initial subscription period committed by the customer commencing when the customer’s environmenthas been created in our hosted environment. The initial subscription period is typically one to three years and the level of service provided each customervaries based on the level of service required by the complexity of a customer’s business.Other RevenueWe recognize revenue for set-up fees, which historically have not been material to our financial statements. We have concluded that set-up fees do not meetthe criteria for separation from our primary service as they do not have stand-alone value as we have historically not sold set-up fees separately. We chargeset-up fees for substantially all new applications and services. These set-up fees are recognized ratably over the contractual period, which approximates thelife of the application. We also sell professional services, which have been immaterial to date.66 Deferred RevenueDeferred revenue includes amounts collected or billed in excess of recognizable revenue. Such amounts are recognized by us over the life of the contractupon meeting the revenue recognition criteria. Deferred revenue that will be recognized during the succeeding 12-month period is recorded as currentdeferred revenue and the remaining portion is recorded as non-current deferred revenue. Because the mix of billing terms with customers can vary from periodto period, the annualized value of the contracts that we enter into with our customers will not be completely reflected in deferred revenue at any single pointin time.Business CombinationsThe results of businesses acquired in a business combination are included in our consolidated financial statements from the date of the acquisition. Purchaseaccounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excessconsideration over the fair value of assets acquired and liabilities assumed is recognized as goodwill.We perform valuations of assets acquired and liabilities assumed on each acquisition accounted for as a business combination and allocate the purchase priceto the tangible and intangible assets acquired and liabilities assumed based on our best estimate of fair value. We determine the appropriate useful life ofintangible assets by performing an analysis of cash flows based on historical experience of the acquired businesses. Intangible assets are amortized over theirestimated useful lives based on the pattern in which the economic benefits associated with the asset are expected to be consumed, which to date hasapproximated the straight-line method of amortization.Transaction costs associated with business combinations are expensed as incurred and are included in general and administrative expense in our consolidatedstatements of operations and comprehensive loss.GoodwillGoodwill represents the excess of the aggregate purchase price paid over the fair value of the net assets acquired in our business combinations. Goodwill isnot amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not berecoverable. Events or changes in circumstances that could trigger an impairment review include a significant adverse change in business climate, an adverseaction or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of our use of the acquired assets orthe strategy for our overall business, significant negative industry or economic trends, or significant underperformance relative to expected historical orprojected future results of operations.We have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is morelikely than not that the fair value of a reporting unit is less than its carrying value, including goodwill. If, after assessing the totality of events orcircumstances, we determine that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, additional impairmenttesting is not required. However, if we conclude otherwise, we are required to perform the first step of a two-step impairment test. Alternatively, we may electto proceed directly to the first step of the two-step impairment test and bypass the qualitative assessment.The first step of the impairment test involves comparing the estimated fair value of a reporting unit with its book value, including goodwill. If the estimatedfair value exceeds book value, goodwill is considered not to be impaired and no additional steps are necessary. If, however, the fair value of the reporting unitis less than book value, the carrying amount of the goodwill is compared to its implied fair value. The estimate of implied fair value of goodwill may requirevaluations of certain internally generated and unrecognized intangible assets. If the carrying amount of goodwill exceeds the implied fair value of thatgoodwill, an impairment loss is recognized in an amount equal to the excess. We test for goodwill impairment on November 30 of each year.67 Software Development CostsWe capitalize the costs of software developed or obtained for internal use in accordance with ASC Topic 350-40, Internal Use Software. Capitalized softwaredevelopment costs consist of costs incurred during the application development stage and include purchased software licenses, implementation costs,consulting costs, and payroll-related costs for projects that qualify for capitalization. These costs relate to major new functionality. All other costs, primarilyrelated to maintenance and minor software fixes, are expensed as incurred.Stock-Based CompensationWe recognize stock-based compensation expense for stock-based compensation awards granted to our employees, directors, consultants and other serviceproviders that can be settled in shares of our common stock. Compensation expense for stock-based compensation awards granted is based on the grant datefair value estimate for each award as determined by our board of directors or the compensation committee of our board of directors. We recognize thesecompensation costs on a straight-line basis over the requisite service period of the award, which is generally four years. As stock-based compensation expenserecognized is based on awards ultimately expected to vest, such expense is reduced for estimated forfeitures.We estimate the fair value of stock-based compensation awards at the date of grant using the Black-Scholes option pricing model, which was developed foruse in estimating the value of traded options that have no vesting restrictions and are freely transferable. The fair values generated by the model may not beindicative of the actual fair values of our awards as it does not consider other factors important to those stock-based payment awards, such as continuedemployment, periodic vesting requirements and limited transferability.Determining the fair value of stock-based awards at the grant date requires judgment. We use the Black-Scholes option-pricing model to determine the fairvalue of stock options. The determination of the grant date fair value of options using an option-pricing model is affected by our estimated common stockfair value as well as assumptions regarding a number of other complex and subjective variables. These variables include the fair value of our common stock,the expected term of the options, our expected stock price volatility, risk-free interest rates, and expected dividends, which are estimated as follows: •Fair value of our common stock. Prior to our initial public offering, the fair value of our common stock was determined by the estimated fairvalue at the time of grant. For stock options granted subsequent to our initial public offering, the fair value of common stock is based on theclosing market price of our common stock as reported on the NASDAQ Global Market on the date of grant. •Expected term. The expected term represents the period that the stock-based compensation awards are expected to be outstanding. Since wedid not have sufficient historical information to develop reasonable expectations about future exercise behavior, we use the simplifiedmethod to compute expected term, which represents the average of the time-to-vesting and the contractual life. •Expected volatility. As we have a limited trading history for our common stock, the expected stock price volatility for our common stock isestimated by taking the average historic price volatility for industry peers based on daily price observations over a period equivalent to theexpected term of the stock option grants. We do not rely on implied volatilities of traded options in our industry peers’ common stockbecause the volume of activity was relatively low. We intend to continue to consistently apply this process using the same or similar publiccompanies until a sufficient amount of historical information regarding the volatility of our own common stock share price becomesavailable. •Risk-free interest rate. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S.Treasury notes with maturities approximately equal to the expected term of the options. •Expected dividend yield. We have never declared or paid any cash dividends and do not presently plan to declare or pay cash dividends inthe foreseeable future. Consequently, we used an expected dividend yield of zero.68 If any of the assumptions used in the Black-Scholes model change significantly, stock-based compensation for future awards may differ materially comparedwith the awards granted previously.The following table presents the weighted-average assumptions used to estimate the fair value of options granted during the periods presented: Year Ended December 31, 2016 2015 2014 Employee Stock Options: Expected term (in years) 5.29 - 6.11 5.09 - 6.15 5.89 - 6.13 Expected volatility 60% - 70% 60% 51.7% - 69% Risk-free interest rate 1.21% - 2.55% 1.41% - 1.94% 1.63% - 2.06% Dividend rate 0% 0% 0% Recent Accounting PronouncementsIn January 2017, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2017-04, Intangibles-Goodwill andOther (Topic 350): Simplifying the Test for Goodwill Impairment. This guidance eliminates Step 2 from the goodwill impairment test, instead requiring anentity to recognize a goodwill impairment charge for the amount by which the goodwill carrying amount exceeds the reporting unit’s fair value. Thisguidance is effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019, and early adoption is permitted.This guidance must be applied on a prospective basis. We expect to adopt this guidance for interim and annual goodwill impairment tests performed ontesting dates after January 1, 2017. We do not expect the adoption of this guidance to have a material impact on our financial position, results of operationsor cash flows.In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This guidance narrows thedefinition of a business. This standard provides guidance to assist entities with evaluating when a set of transferred assets and activities is a business. Thisguidance is effective for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted. This guidance must beapplied prospectively to transactions occurring within the period of adoption. We expect to adopt this guidance effective January 1, 2018. We do not expectthe adoption of this guidance to have a material impact on our financial position, results of operations or cash flows.In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This guidance requires that a statement of cashflows explain the change during the period in the total of cash, cash equivalents, and restricted cash. As a result, restricted cash will be included with cash andcash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new guidance iseffective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, and the new guidanceis to be applied retrospectively. We not expect the adoption of this guidance to have a material impact on our cash flows.In September 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. Thisguidance clarifies the presentation requirements of eight specific issues within the statement of cash flows. The new guidance is effective for fiscal yearsbeginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expectedto have a significant impact on our financial statements, as our treatment of the relevant affected items within its consolidated statement of cash flows isconsistent with the requirements of this guidance.In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based PaymentAccounting. This standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact,classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning afterDecember 15, 2016, and early adoption is permitted. The ASU will be effective for us in the first quarter of 2017. We do not expect this ASU to have amaterial impact on our consolidated financial statements.69 In February, 2016, the FASB issued ASU 2016-02, Leases. The standard will affect all entities that lease assets and will require lessees to recognize a leaseliability and a right-of-use asset for all leases (except for short-term leases that have a duration of less than one year) as of the date on which the lessor makesthe underlying asset available to the lessee. For public companies, the new standard is effective for fiscal years beginning after December 15, 2018, includinginterim periods within those fiscal years. Early adoption is permitted. For leases existing at, or entered into after, the beginning of the earliest comparativeperiod presented in the financial statements, lessees and lessors must apply a modified retrospective transition approach. We are still evaluating the effect thatthis guidance will have on our consolidated financial statements and related disclosures.In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. Thenew standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carryingamount of that debt liability. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015.We adopted this standard retrospectively in the first quarter of 2016. The balance sheet as of December 31, 2015 was retrospectively adjusted, which resultedin reductions to other assets of $0.1 million and long-term debt of $0.1 million.In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards forrevenue recognition. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,which delays the effective date of ASU 2014-09 by one year. The FASB also agreed to allow entities to choose to adopt the standard as of the originaleffective date. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations(Reporting Revenue Gross versus Net) which clarifies the implementation guidance on principal versus agent considerations. The guidance includesindicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The new revenuerecognition standard will be effective for us in the first quarter of 2018, with the option to adopt it in the first quarter of 2017. We currently anticipateadopting the new standard effective January 1, 2018. The new standard also permits two methods of adoption: retrospectively to each prior reporting periodpresented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initialapplication (the modified retrospective method). We currently anticipate adopting the standard using the modified retrospective method. We are still in theprocess of completing our analysis on the impact this guidance will have on our consolidated financial statements and related disclosures.Item 7A. Quantitative and Qualitative Disclosures About Market Risk.Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market riskexposure is primarily the result of fluctuations in interest rates and foreign exchange rates as well as, to a lesser extent, inflation.Interest Rate RiskWe are exposed to interest rate risk in the ordinary course of our business. Our cash equivalents includes cash in readily available checking and moneymarket accounts and marketable securities. These securities are not dependent on interest rate fluctuations that may cause the principal amount of these assetsto fluctuate.We had cash and cash equivalents of $60.8 million as of December 31, 2016, which consisted of bank deposits and money market funds. To date, fluctuationsin interest income have not been significant. We have no outstanding debt subject to interest rate risk as of December 31, 2016. Amounts outstanding underour revolving line of credit carry a variable interest rate of the prime rate, but in no event less than 3.25%, plus 0.75%. As of December 31, 2016, theapplicable prime rate was 3.75%. We monitor our cost of borrowing under our revolving line of credit, if any, taking into account our funding requirements,and our expectation for short-term rates in the future.70 We do not enter into investments for trading or speculative purposes and have not used any derivative financial instruments to manage our interest rate riskexposure. Although our credit facility and term loan have variable interest rates, a hypothetical 10% change in interest rates during any of the periodspresented would not have had a material impact on our financial statements.Foreign Currency Exchange RiskWe have foreign currency risks related to our revenue and operating expenses denominated in currencies other than our functional currency, the U.S. dollar,principally British pounds. Movements in foreign currencies in which we transact business could significantly affect future net earnings. We do not currentlyengage in any hedging activity to reduce our potential exposure to currency fluctuations, although we may choose to do so in the future. A hypothetical 10%change in foreign exchange rates during any of the periods presented would not have had a material impact on our consolidated financial statements. As ourinternational operations grow, we will continue to reassess our approach to manage our risk relating to fluctuations in foreign currency rate.Inflation RiskWe do not believe that inflation has had a material effect on our business, financial condition or results of operations. If our costs were to become subject tosignificant inflationary pressures, we may not be able to fully offset such higher costs through price increases. Our inability or failure to do so could harm ourbusiness, financial condition and results of operations.JOBS Act Transition PeriodIn April 2012, the Jumpstart Our Business Startups Act of 2012, or the JOBS Act, was enacted. Section 107 of the JOBS Act provides that an “emerginggrowth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revisedaccounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwiseapply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new orrevised accounting standards on the relevant dates on which adoption of such standards is required for other public companies.We are relying on other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions, as an emerging growthcompany, we may rely on certain of these exemptions, including without limitation, (i) providing an auditor’s attestation report on our system of internalcontrols over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (ii) complying with any requirement that may be adopted by thePublic Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additionalinformation about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an emerging growth company untilthe earlier to occur of (1) the last day of the fiscal year (a) following the fifth anniversary of the completion of our initial public offering, (b) in which we havetotal annual gross revenues of at least $1.0 billion or (c) in which we are deemed to be a “large accelerated filer” under the rules of the U.S. Securities andExchange Commission, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the prior June 30th, and(2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.Item 8.

We do not consider these items to be indicative of our core operating performance. The items that are non-cash include depreciation and amortizationexpense and stock-based compensation expense. Adjusted EBITDA is a measure used by management to understand and evaluate our core operating performance and trendsand to generate future operating plans, make strategic decisions regarding the allocation of capital and invest in initiatives that are focused on cultivating new markets for oursolutions. In particular, the exclusion of certain expenses in calculating adjusted EBITDA facilitates comparisons of our operating performance on a period-to-period basis.Adjusted EBITDA is not a measure calculated in accordance with GAAP. The following table presents a reconciliation of adjusted EBITDA to net loss, the most directlycomparable GAAP measure, for each of the periods indicated. See “Management’s Discussion & Analysis of Financial Conditions and Results of Operations—Other Metrics”for a discussion of the limitations of adjusted EBITDA.

The increase in revenue was partially offset by increases in amortizationexpense attributed to our acquisitions and capitalized software development costs. Quarterly Trends in Operating Expenses Our operating expenses generally have increased sequentially for the periods presented due primarily to increases in headcount and other office andinfrastructure related expenses to support our growth and becoming a public company. We anticipate our operating expenses will continue to increase inabsolute dollar terms as we invest in the long-term growth of our business. Item 9. Changes in and Disagreements With Accountants on Accounting and Financial Disclosure.NoneItem 9A. Controls and Procedures.Evaluation of Disclosure Controls and ProceduresWe maintain “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, orthe Exchange Act, that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under theExchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls andprocedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports thatit files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principalfinancial officers, as appropriate to allow timely decisions regarding required disclosure.Our management, with the participation of our principal executive officer and principal financial officer, has evaluated the effectiveness of our disclosurecontrols and procedures as of the end of the period covered by this Annual Report on Form 10-K. Based on such evaluation, our principal executive officerand principal financial officer have concluded that as of such date, our disclosure controls and procedures were effective at a reasonable assurance level as ofDecember 31, 2016.Management’s Annual Report on Internal Control Over Financial ReportingThis Annual Report on Form 10-K does not include a report of management’s assessment regarding internal control over financial reporting due to atransition period established by rules of the Securities and Exchange Commission for newly public companies.Inherent Limitations on Effectiveness of ControlsOur management, including our principal executive officer and principal financial officer, does not expect that our disclosure controls and procedures or ourinternal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, canprovide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems,no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. Thedesign of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that anydesign will succeed in achieving its stated goals under all potential future conditions. Over time, controls may become inadequate because of changes inconditions, or the degree of compliance with the policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system,misstatements due to error or fraud may occur and not be detected.73 Changes in Internal Control over Financial ReportingThere was no change in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d)of the Exchange Act that occurred during the period covered by this Annual Report on Form 10-K that has materially affected, or is reasonably likely tomaterially affect, our internal control over financial reporting.Item 9B.

F-6 Everbridge, Inc.Notes to the Consolidated Financial Statements(1) Business and Nature of OperationsEverbridge, Inc., a Delaware corporation (together with its wholly-owned subsidiaries, referred to as “Everbridge” or the “Company”), is a global softwarecompany that provides critical communications and enterprise safety applications that enable customers to automate and accelerate the process of keepingpeople safe and businesses running during critical events. The Company’s SaaS-based platform enables the Company’s customers to quickly and reliablydeliver messaging to a large group of people during critical situations. The Company’s enterprise applications, such as Mass Notification, IncidentManagement, IT Alerting, Safety Connection, Community Engagement, Secure Messaging, Crisis Commander and Visual Command Center, automatenumerous critical communications processes. The Company generates revenue primarily from subscription fees to the Company’s enterprise applications.The Company has operations in the United States, Sweden, the United Kingdom and China.Initial Public OfferingOn September 21, 2016, the Company completed an initial public offering, or IPO, in which the Company sold 6,250,000 shares of its common stock at thepublic offering price of $12.00 per share. The Company received net proceeds of $66.1 million, after deducting underwriting discounts and commissions andoffering expenses paid and payable by the Company, from sales of its shares in the IPO. In connection with the closing of the IPO, all shares of Class Acommon stock then outstanding were converted into 1,164,105 shares of common stock and all shares of convertible preferred stock then outstanding wereconverted into 8,354,963 shares of common stock, in each case on a one-to-one basis.(2) Summary of Significant Accounting PoliciesBasis of PresentationThe accompanying consolidated financial statements include the Company’s results of operations and those of its wholly-owned subsidiaries. Allintercompany transactions and balances have been eliminated in consolidation. The Company’s accounting and financial reporting policies conform togenerally accepted accounting principles in the United States of America, or U.S. GAAP.Principles of ConsolidationThe consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. Business acquisitions are included in theCompany’s consolidated financial statements from the date of the acquisition. The Company’s purchase accounting resulted in all assets and liabilities ofacquired businesses being recorded at their estimated fair values on the acquisition dates.Use of EstimatesThe preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect thereported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and thereported amount of revenues and expenses during the reporting period. Actual results could differ from those estimates.Assets and liabilities which are subject to judgment and use of estimates include allowances for doubtful accounts, the fair value of assets acquired andliabilities assumed in business combinations, the recoverability of goodwill and long-lived assets, valuation allowances with respect to deferred tax assets,useful lives associated with property and equipment and intangible assets, contingencies, and the valuation and assumptions underlying stock-basedcompensation. On an ongoing basis, the Company evaluates its estimates compared to historical experience and trends, which form the basis for makingjudgments about the carrying value of assets and liabilities.F-7 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) Recent Accounting StandardsIn January 2017, the Financial Accounting Standards Board, or FASB, issued Accounting Standards Update, or ASU, 2017-04, Intangibles-Goodwill andOther (Topic 350): Simplifying the Test for Goodwill Impairment. This guidance eliminates Step 2 from the goodwill impairment test, instead requiring anentity to recognize a goodwill impairment charge for the amount by which the goodwill carrying amount exceeds the reporting unit’s fair value. Thisguidance is effective for interim and annual goodwill impairment tests in fiscal years beginning after December 15, 2019, and early adoption is permitted.This guidance must be applied on a prospective basis. The Company expects to adopt this guidance for interim and annual goodwill impairment testsperformed on testing dates after January 1, 2017. The Company does not expect the adoption of this guidance to have a material impact on its financialposition, results of operations or cash flows.In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This guidance narrows thedefinition of a business. This standard provides guidance to assist entities with evaluating when a set of transferred assets and activities is a business. Thisguidance is effective for interim and annual reporting periods beginning after December 15, 2017, and early adoption is permitted. This guidance must beapplied prospectively to transactions occurring within the period of adoption. The Company expects to adopt this guidance effective January 1, 2018. TheCompany does not expect the adoption of this guidance to have a material impact on its financial position, results of operations or cash flows.In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This guidance requires that a statement of cashflows explain the change during the period in the total of cash, cash equivalents, and restricted cash. As a result, restricted cash will be included with cash andcash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new guidance iseffective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, and the new guidanceis to be applied retrospectively. The Company does not expect the adoption of this guidance to have a material impact on its cash flows.In September 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. Thisguidance clarifies the presentation requirements of eight specific issues within the statement of cash flows. The new guidance is effective for fiscal yearsbeginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance is not expectedto have a significant impact on the Company’s financial statements, as the Company's treatment of the relevant affected items within its consolidatedstatement of cash flows is consistent with the requirements of this guidance.In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based PaymentAccounting. This standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact,classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning afterDecember 15, 2016, and early adoption is permitted. The ASU will be effective for the Company in the first quarter of 2017. The Company does not expectthis ASU to have a material impact on its consolidated financial statements.In February, 2016, the FASB issued ASU 2016-02, Leases. The standard will affect all entities that lease assets and will require lessees to recognize a leaseliability and a right-of-use asset for all leases (except for short-term leases that have a duration of less than one year) as of the date on which the lessor makesthe underlying asset available to the lessee. For public companies, the new standard is effective for fiscal years beginning after December 15, 2018, includinginterim periods within those fiscal years. Early adoption is permitted. For leases existing at, or entered into after, the beginning of the earliest comparativeperiod presented in the financial statements, lessees and lessors must apply a modified retrospective transition approach. The Company is still evaluating theeffect that this guidance will have on its consolidated financial statements and related disclosures.In April 2015, the FASB issued ASU 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. Thenew standard requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carryingamount of that debt liability. TheF-8 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. The Company adopted thisstandard retrospectively in the first quarter of 2016. The balance sheet as of December 31, 2015 was retrospectively adjusted, which resulted in reductions toother assets of $0.1 million and long-term debt of $0.1 million.In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which amends the existing accounting standards forrevenue recognition. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date,which delays the effective date of ASU 2014-09 by one year. The FASB also agreed to allow entities to choose to adopt the standard as of the originaleffective date. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations(Reporting Revenue Gross versus Net), which clarifies the implementation guidance on principal versus agent considerations. The guidance includesindicators to assist an entity in determining whether it controls a specified good or service before it is transferred to the customers. The new revenuerecognition standard will be effective for the Company in the first quarter of 2018, with the option to adopt it in the first quarter of 2017. The Companycurrently anticipates adopting the new standard effective January 1, 2018. The new standard also permits two methods of adoption: retrospectively to eachprior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at thedate of initial application (the modified retrospective method). The Company currently anticipates adopting the standard using the modified retrospectivemethod. The Company is still in the process of completing its analysis on the impact this guidance will have on its consolidated financial statements andrelated disclosures.Fair Value MeasurementsFair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or mostadvantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Accountingstandards describe a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable, that maybe used to measure fair value which are the following:Level 1—Quoted prices in active markets for identical assets or liabilities or funds.Level 2—Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quotedprices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the fullterm of the assets or liabilities.Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.Contingent Consideration LiabilityThe Company recorded a contingent consideration liability upon the acquisition of Svensk Krisledning AB, or Crisis Commander, on December 30, 2016(See Note 5). Contingent consideration is measured at fair value and is based on significant inputs not observable in the market, which represents a Level 3measurement within the fair value hierarchy. The valuation of contingent consideration uses assumptions the Company believes would be made by a marketparticipant. The Company assesses these estimates on an on-going basis as additional data impacting the assumptions is obtained. Changes in the fair valueof contingent consideration related to updated assumptions and estimates are recognized within the consolidated statements of operations andcomprehensive loss. The Company determined the fair value of the contingent consideration using the probability adjusted discounted cash flow method.The significant unobservable inputs used in the fair value measurement of contingent consideration are the probabilities of achieving sales milestones, theperiod in which these milestones are expected to be achieved, and discount rates. At December 31, 2016, it was determined to be probable that the Companywould achieve the sales milestones as included in the Crisis Commander purchase agreement. This resulted in the recognition of an obligation of$0.4 million at December 31, 2016, which is classified under other long term liabilities. There was no change in the fair value of contingent considerationliability during the year ended December 31, 2016.F-9 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) Significant increases or decreases in the probabilities of achieving the milestones would result in a significantly higher or lower fair value measurement,respectively. Significant increases or decreases in the period in which milestones will be achieved would result in a significantly lower or higher fair valuemeasurement, respectively. The Company expects to pay the contingent consideration in March of 2018.Concentrations of Credit and Business RiskFinancial instruments that potentially subject the Company to a concentration of credit risk consist of cash, cash equivalents and accounts receivable.The Company maintains cash and cash equivalent balances at several banks. Accounts located in the United States are insured by the Federal DepositInsurance Corporation, or FDIC, up to $250,000. From time to time, balances may exceed amounts insured by the FDIC. The Company has not experiencedany losses in such amounts.The Company’s accounts receivable are generally unsecured and are derived from revenue earned from customers located in the United States and the UnitedKingdom and are generally denominated in U.S. dollars or British pounds. Each reporting period, the Company reevaluates each customer’s ability to satisfycredit obligations and maintains an allowance for doubtful accounts based on the evaluations. No single customer comprised more than 10% of theCompany’s total revenue for the years ended December 31, 2016 and 2015. No single customer comprised more than 10% of the Company’s accountsreceivable balance at December 31, 2016 and 2015.Cash and Cash EquivalentsThe Company considers all highly liquid investments purchased with an original maturity of three months or less to be cash equivalents. Cash equivalentsconsist of funds deposited into money market funds. Cash and cash equivalents are stated at cost which approximates fair value.Accounts ReceivableAccounts receivable includes trade accounts receivables from the Company’s customers, net of an allowance for doubtful accounts. Accounts receivable arerecorded at the invoiced amount and do not bear interest. Allowance for doubtful accounts is established based on various factors including credit profiles ofthe Company’s customers, historical payments and current economic trends. The Company reviews its allowance by assessing individual accounts receivableover a specific aging and amount and all other balances are pooled based on historical collection experience. Accounts receivable are written-off on a case bycase basis, net of any amounts that may be collected.Deferred CommissionsThe Company capitalizes commission costs earned by sales personnel that are incremental and directly related to the acquisition of customer contracts.Commission costs are accrued and capitalized upon execution of the sales contract by the customer. Payments to sales personnel are made shortly after thereceipt of the related customer payment. Commissions are earned based on annual billings and are not earned on multi-year contracts until the annual billingis renewed. Deferred commissions are amortized over the commissionable portion of the contract which is subject to clawback should the customer cancel,which generally can only occur if the Company materially fails to perform under the contract. Amortization of deferred commissions is included in sales andmarketing expenses in the accompanying consolidated statements of operations and comprehensive loss. Deferred commissions, net of amortization, areincluded in other assets in the accompanying consolidated balance sheet.Deferred Offering CostsDeferred offering costs consist primarily of direct incremental costs related to the Company’s proposed IPO of its common stock. Upon the completion of theCompany’s IPO in September 2016, $3.6 million was offset against the proceeds of the offering.F-10 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) Property and Equipment, NetProperty and equipment are stated at cost, less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated usefullives of the assets, which is generally three years for computer software, office computers and system software, five years for system hardware and furnitureand equipment, and over the shorter of lease term or useful life of the assets for leasehold improvements. Maintenance and repairs are expensed as incurred.When assets are retired or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any resulting gain or lossis reflected in the Company’s results of operations.Assets held under capital lease are recorded at the net present value of the minimum lease payments of the leased asset at the inception of the lease.Depreciation expense is computed using the straight-line method over the shorter of the estimated useful lives of the asset or the period of the related lease forleasehold improvements.Capitalized Software Development CostsThe Company capitalizes the costs of software developed or obtained for internal use in accordance with ASC Topic 350-40, Internal Use Software.Capitalized software development costs consist of costs incurred during the application development stage and include purchased software licenses,implementation costs, consulting costs, and payroll-related costs for projects that qualify for capitalization. These costs relate to major new functionality. Allother costs, primarily related to maintenance and minor software fixes, are expensed as incurred.The Company amortizes the capitalized software development costs on a straight-line basis over the estimated useful life of the software, which is generallythree years, beginning when the asset is substantially ready for use. The amortization of capitalized software development costs is reflected in cost of revenue.Business CombinationsThe results of businesses acquired in a business combination are included in the Company’s consolidated financial statements from the date of acquisition.Purchase accounting results in assets and liabilities of an acquired business being recorded at their estimated fair values on the acquisition date. Any excessconsideration over the value of the assets acquired and liabilities assumed is recognized as goodwill.The Company performs valuations of assets acquired and liabilities assumed on each acquisition accounted for as a business combination, and allocates thepurchase price to the tangible and intangible assets acquired and liabilities assumed based on its best estimate of fair value. Acquired intangible assetsinclude: tradenames, customer relationships, and developed technology. The Company determines the appropriate useful life of intangible assets byperforming an analysis of cash flows based on historical experience of the acquired businesses. Intangible assets are amortized over their estimated usefullives based on the pattern in which the economic benefits associated with the asset are expected to be consumed, which to date has approximated the straight-line method of amortization. The estimated useful lives for tradenames, customer relationships, and technology are generally, two to seven years, five years,and two to three years, respectively.Long Lived AssetsThe Company evaluates the recoverability of its long lived assets with finite useful lives for impairment whenever events or changes in circumstancesindicate that the carrying amounts may not be recoverable. The Company performs impairment testing at the asset group level that represents the lowest levelfor which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. If events or changes in circumstances indicate thatthe carrying amount of an asset group may not be recoverable and the expected undiscounted future cash flows attributable to the asset group are less thanthe carrying amount of the asset group, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Fair value isdetermined based upon estimated discounted future cash flows, if any.F-11 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) GoodwillGoodwill represents the excess of the aggregate purchase price paid over the fair value of the net assets acquired in our business combinations. Goodwill isnot amortized and is tested for impairment at least annually or whenever events or changes in circumstances indicate that the carrying value may not berecoverable. Events or changes in circumstances that could trigger an impairment review include a significant adverse change in business climate, an adverseaction or assessment by a regulator, unanticipated competition, a loss of key personnel, significant changes in the manner of our use of the acquired assets orthe strategy for our overall business, significant negative industry or economic trends, or significant underperformance relative to expected historical orprojected future results of operations. The Company has the option to first assess qualitative factors to determine whether the existence of events orcircumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying value, including goodwill.If, after assessing the totality of events or circumstances, the Company determines that it is not more likely than not that the fair value of a reporting unit isless than its carrying amount, additional impairment testing is not required. However, if the Company concludes otherwise, the Company is required toperform the first step of a two-step impairment test. Alternatively, the Company may elect to proceed directly to the first step of the two-step impairment testand bypass the qualitative assessment. The first step of the impairment test involves comparing the estimated fair value of a reporting unit with its bookvalue, including goodwill. If the estimated fair value exceeds book value, goodwill is considered not to be impaired and no additional steps are necessary. If,however, the fair value of the reporting unit is less than book value, the carrying amount of the goodwill is compared to its implied fair value. The estimate ofimplied fair value of goodwill may require valuations of certain internally generated and unrecognized intangible assets. If the carrying amount of goodwillexceeds the implied fair value of that goodwill, an impairment loss is recognized in an amount equal to the excess. The Company tests for goodwillimpairment annually on November 30.The Company performed a qualitative goodwill assessment at November 30, 2016 and concluded there was no impairment based on consideration of anumber of factors, including the improvement in the Company’s key operating metrics over the prior year, improvement in the strength of the generaleconomy and the Company’s continued execution against its overall strategic objectives.Based on the foregoing, the Company determined that it was not more likely than not that the fair value of its reporting unit is less than its carrying amountand therefore that no further impairment testing was required.Revenue RecognitionThe Company derives substantially all of its revenue from contract subscription fees for use of its applications. The Company recognizes revenues inaccordance with ASC 605, and accordingly revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixedor determinable, collectability is reasonably assured and acceptance criteria, if any, have been met. If any of these criteria are not met, revenue recognition isdeferred until such time that all of the criteria are met. The Company’s subscription arrangements do not provide customers with the right to take possessionof the software at any time.Subscription RevenueSubscription revenue is recognized ratably over the initial subscription period committed by the customer commencing when the customer’s environmenthas been created in the Company’s hosted environment. The initial subscription period is typically one to three years and the level of service provided eachcustomer varies based on the level of service required by the complexity of a customer’s business. The level of service also specifies the level of usage by thecustomer in terms of minutes or data used to transmit the notifications. In the event actual usage exceeds the level purchased, overages are invoiced and arerecorded as revenue during the service period. The subscription services are noncancelable, although customers have the right to terminate their contracts ifthe Company materially fails to perform. The Company generally invoices the Company’s customers in advance in annual installments for the subscriptionfees, including the set-up fees on the first annual invoice.F-12 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) Other RevenueThe Company recognizes revenue for set-up fees, which historically have not been material to the Company’s financial statements. The Company hasconcluded that set-up fees do not meet the criteria for separation from the Company’s primary service as they do not have stand-alone value as the Companyhas historically not sold set-up fees separately. Since set-up fees are charged for substantially all new applications and services, they are recognized ratablyover the contractual period, which approximates the life of the application. The Company also sells professional services, which have been immaterial todate.Deferred RevenueDeferred revenue includes amounts collected or billed in excess of recognizable revenue. Such amounts are recognized by the Company over the life of thecontract upon meeting the revenue recognition criteria. Deferred revenue that will be recognized during the succeeding 12-month period is recorded ascurrent deferred revenue and the remaining portion is recorded as non-current deferred revenue.Cost of RevenueCost of revenue includes expenses related to the fulfillment of the Company’s subscription services, consisting primarily of employee-related expenses fordata center operations and customer support, including salaries, bonuses, benefits and stock-based compensation expense. Cost of revenue also includeshosting costs, messaging costs and depreciation and amortization.Advertising ExpensesAdvertising expenses to promote the Company’s services are expensed as incurred. Advertising expenses included in sales and marketing expense were $1.1million, $0.8 million and $0.3 million for the years ended December 31, 2016, 2015 and 2014, respectively.Research and DevelopmentResearch and development expenses primarily consist of employee-related costs for research and development staff, including salaries, bonuses, benefits andstock-based compensation and the cost of certain third-party service providers related to the development of the Company’s solutions that do not meet thecriteria to be capitalized under ASC Topic 350-40, Internal Use Software.Stock-Based CompensationStock-based compensation expense is comprised of stock options, which are issued under the Company’s 2008 and 2016 equity incentive plans, andrestricted stock awards, or RSAs, and employee stock purchase plan awards.Stock-based compensation related to stock options and RSAs is measured at the grant date based on the fair value of the award and is recognized straight-lineas expense, net of estimated forfeitures, over the requisite service period, which is generally the vesting period of the respective award. The Company utilizesthe Black-Scholes pricing model for determining the estimated fair value of the stock options and RSAs. The Black-Scholes pricing model requires the use ofsubjective assumptions including the option’s expected term, the volatility of the underlying stock, the fair value of the stock and the expected forfeiturerate.Income TaxesThe Company accounts for income taxes using the asset and liability method of accounting for income taxes in which deferred tax assets and liabilities arerecognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities andtheir respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in whichthose temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized asincome in the period that includes the enactment date. A valuation allowance is established if it is more likely than not that all or a portion of the deferred taxasset will not be realized.F-13 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) The calculation of the Company’s tax liabilities involves dealing with uncertainties of the application of complex tax regulations. The Company recognizesliabilities for uncertain tax positions based on a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weightof available evidence indicates it is more likely than not, that the position will be sustained on audit, including resolution of related appeals or litigationprocesses, if any. The second step is to measure the tax benefit as the largest amount, which is more than 50% likely of being realized upon ultimatesettlement. The Company considers many factors when evaluating and estimating its tax positions and tax benefits, which may require periodic adjustments.Foreign Currency TranslationThe functional currency for the Company’s foreign subsidiaries is the local currency. For those subsidiaries, the assets and liabilities are translated into U.S.dollars at the exchange rate method at the balance sheet date. Income and expenses are translated at the average exchange rates for the period. Foreigncurrency exchange gain and losses are recorded in other expenses.Other Comprehensive Income (Loss)For all periods presented, the Company’s other comprehensive income (loss) is comprised of foreign currency translation adjustments related to theCompany’s foreign subsidiaries.Net Loss Per Share Attributable to Common StockholdersBasic net loss per share attributable to common stockholders is computed by dividing the Company’s net loss attributable to common stockholders by theweighted-average number of common shares used in the loss per share calculation during the period. Diluted net loss per share attributable to commonstockholders is computed by giving effect to all potentially dilutive securities, including stock options, restricted stock awards and warrants. Basic anddiluted net loss per share attributable to common stockholders was the same for all periods presented as the inclusion of all potentially dilutive securitiesoutstanding was anti-dilutive.(3) Accounts Receivable, NetAccounts receivable, net, is as follows (in thousands): As of December 31, 2016 2015 Accounts receivable $18,231 $16,080 Allowance for doubtful accounts (419) (381)Net accounts receivable $17,812 $15,699 Bad debt expense for the years ended December 31, 2016, 2015 and 2014 was $0.4 million, $0.4 million and $0.2 million, respectively.The following table summarizes the changes in the allowance for doubtful accounts (in thousands): As of December 31, 2016 2015 Allowance, at beginning of period $(381) $(282)Charged to bad debt expense (387) (366)Write-offs, net of recoveries 349 267 Allowance, at end of period $(419) $(381) F-14 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) (4) Property and EquipmentProperty and equipment consists of the following at December 31, 2016 and 2015 (in thousands): 'Useful life As of December 31, in years 2016 2015 Furniture and equipment 5 $928 $822 System hardware 5 3,320 6,495 Office computers 3 1,777 2,003 Computer and system software 3 1,478 1,341 7,503 10,661 Less accumulated depreciation and amortization (4,580) (7,041)Property and equipment, net $2,923 $3,620 Depreciation and amortization expense for the years ended December 31, 2016, 2015 and 2014 was $1.7 million, $1.4 million and $0.7 million, respectively.(5) GoodwillGoodwill was $9.7 million and $7.8 million as of December 31, 2016 and 2015, respectively. There were no impairments recorded against goodwill in 2016,2015 or 2014. The following table displays the changes in the gross carrying amount of goodwill (in thousands): Amount Balance at December 31, 2015 and 2014 $7,839 Crisis Commander acquisition 1,837 Balance at December 31, 2016 $9,676 AcquisitionOn December 30, 2016, the Company completed the acquisition of Crisis Commander, a privately held SaaS mobile crisis management company based out ofNorsburg, Sweden. The acquisition was consummated pursuant to a purchase agreement for an initial preliminary purchase price of $2.7 million, subject toearn out payments contingent on meeting certain revenue thresholds which are expected to be paid in March 2018.The excess of purchase consideration over the fair value of net tangible liabilities assumed and identifiable intangible assets acquired was recorded asgoodwill. The fair values assigned to tangible and identifiable intangible assets acquired and liabilities assumed are based on management’s estimates andassumptions. The estimated fair values of assets acquired and liabilities assumed may be subject to change as additional information is received. Thus, theprovisional measurements of fair value have been recorded.The goodwill balance is primarily attributed to the anticipated synergies from the acquisition and expanded market opportunities with respect to theintegration of Crisis Commander’s platform with the Company's other solutions. The goodwill balance is not deductible for U.S. income tax purposes.The assets and results of operations of Crisis Commander were not significant to the Company’s consolidated financial position or results of operations, andthus pro forma information is not presented.(6) Fair Value MeasurementsThe carrying amounts of cash and cash equivalents, accounts receivable, accounts payable, capital leases and accrued liabilities approximate fair valuebecause of the short maturity of these items. The fair value of the Company’s revolving line of credit and term loan approximates carrying value based on theCompany’s current incremental borrowing rate for similar types of borrowing arrangements. The fair value of the Company’s notes payable approximatescarrying value due to the short term nature of the arrangement.F-15 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) Certain assets, including long-lived assets, goodwill and intangible assets are also subject to measurement at fair value on a non-recurring basis if they aredeemed to be impaired as a result of an impairment review. For the years ended December 31, 2016 and 2015, no impairments were identified of those assetsrequiring measurement at fair value on a non-recurring basis.The following table summarizes the Company's financial assets and liabilities measured at fair value on a recurring basis at December 31, 2016 by levelwithin the fair value hierarchy. There were no financial assets and liabilities that were required to be measured at fair value basis on a non-recurring basis atDecember 31, 2015. Financial assets and financial liabilities are classified in their entirety based on the lowest level of input that is significant to the fairvalue measurement: At December 31, 2016 Quoted Significant Prices in Other Significant Active Observable Unobservable Markets Inputs Inputs Total Fair (Level 1) (Level 2) (Level 3) Value (in thousands) Assets: Money market funds (included in cash and cash equivalents) $57,032 — — $57,032 Total financial assets $57,032 $— $— $57,032 Liabilities: Contingent consideration — — $388 $388 Total financial liabilities $— $— $388 $388 The following table summarizes the changes in Level 3 financial instruments (in thousands).

Amortization of capitalized software development costs is classified within cost of revenue in the consolidatedstatements of operations and comprehensive loss.The expected amortization, as of December 31, 2016, for each of the next three years is as follows: Year ending December 31: (in thousands) 2017 $4,361 2018 2,844 2019 1,587 $8,792 (8) Intangible AssetsIntangible assets consisted of the following finite lived intangible assets at December 31, 2016 and 2015 (in thousands): As of December 31, 2016 Grosscarryingamount Weighted-average life(years) Accumulatedamortization Netcarryingamount Amortizable intangible assets: Developed technology $1,490 3.60 $(878) $612 Tradenames 883 6.08 (254) 629 Customer relationships 4,779 5.00 (2,080) 2,699 Total intangible assets $7,152 $(3,212) $3,940 As of December 31, 2015 Grosscarryingamount Weighted-average life(years) Accumulatedamortization Netcarryingamount Amortizable intangible assets: Developed technology $1,211 3.07 $(763) $448 Tradenames 582 5.55 (223) 359 Customer relationships 4,941 5.00 (1,629) 3,312 Total intangible assets $6,734 $(2,615) $4,119 Total amortization expense for the years ended December 31, 2016, 2015 and 2014 was $1.2 million, $1.5 million and $1.0 million, respectively.Amortization expense of tradenames and customer relationships is included within general and administrative expenses, while amortization of developedtechnology is included in cost of revenue. The Company recorded amortization expense attributed to developed technology of $0.2 million, $0.4 millionand $0.2 million for the period ended December 31, 2016, 2015 and 2014, respectively.F-17 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) The expected amortization of the intangible assets, as of December 31, 2016, for each of the next five years and thereafter is as follows: (in thousands) 2017 $1,392 2018 1,221 2019 772 2020 262 2021 263 Thereafter 30 $3,940 (9) Income TaxesThe components of loss before income taxes are as follows: Year Ended December 31, 2016 2015 2014 (in thousands) Domestic $(8,572) $(8,016) $395 Foreign (2,738) (3,370) (1,107)Total $(11,310) $(11,386) $(712) For purposes of the reconciling the Company’s provision for income taxes at the statutory rate and the Company’s provision (benefit) for income taxes at theeffective tax rate, a notional 34% tax rate was applied as follows: Year Ended December 31, 2016 2015 2014 (in thousands) Income tax at federal statutory rate $(3,846) $(3,871) $(242)Increase/(Decrease) in tax resulting from: State income tax expense, net of federal tax effect (183) (103) 9 Nondeductible permanent items 1,012 567 123 Foreign rate differential 662 474 228 State rate change (13) (74) 9 Adjustment to deferred taxes (132) (525) (2)Change in valuation allowance 2,351 2,921 (248)Uncertain tax positions 83 50 12 Other 42 (1) 22 Total $(24) $(562) $(89) The difference between the statutory federal income tax rate and the Company’s effective tax rate in 2016, 2015 and 2014 is primarily attributable to theeffect of state income taxes, difference between the U.S. and foreign tax rates, deferred tax state rate adjustment, share-based compensation and other non-deductible permanent items, and the change in valuation allowance. The Company’s China, Sweden and U.K. subsidiaries were subject to 25%, 22% and20% applicable statutory income tax rates, respectively, for the periods presented.F-18 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) The provision for (benefit from) income taxes is as follows: Year Ended December 31, 2016 2015 2014 (in thousands) Current: Federal $— $(14) $16 State 31 4 24 Foreign 109 (101) 191 140 (111) 231 Deferred: Federal (1,823) (2,536) 255 State (396) (315) (1)Foreign (296) (521) (326) (2,515) (3,372) (72)Change in valuation allowance 2,351 2,921 (248)Total $(24) $(562) $(89) The net deferred tax assets (liabilities) at December 31, 2016 and 2015 are comprised of the following: As of December 31, 2016 2015 (in thousands) Deferred rent $47 $110 AMT credit 31 50 Accrued expenses 1,091 1,341 Deferred revenue 441 359 Net operating loss carryforward 18,722 15,737 Other assets 423 411 Intangible assets (2,173) (1,524)Property and equipment (166) (282)Other liabilities (28) (16)Valuation allowance (18,882) (16,531)Total non-current deferred income tax liabilities $(494) $(345) In November 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes, requiring all deferred tax assets and liabilities, and anyrelated valuation allowance, to be classified as non-current on the balance sheet. The Company elected to retrospectively adopt the accounting standard inthe fourth quarter of 2015.Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existingdeferred tax assets. A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended December31, 2016. Such objective evidence limits the ability to consider other subjective evidence such as its projections for future growth. On the basis of thisevaluation, at December 31, 2016 and 2015, a valuation allowance of $18.9 million and $16.5 million, respectively, has been recorded since it is more likelythan not that the deferred tax assets will not be realized.At December 31, 2016, the Company has federal and state net operating loss carryforwards of $46.2 million and $40.5 million, respectively, which expire invarying amounts through 2036. At December 31, 2015, the Company has federal and state net operating loss carryforwards of $39.2 million and $36.6million, respectively. Section 382 of the Internal Revenue Code, or Section 382, imposes limitations on a corporation’s ability to utilize its Net OperatingLosses, or NOLs, if it experiences an “ownership change.” In general terms, an ownership change may result from transactions increasing the ownershippercentage of certain stockholders in the stock of the corporation by more than 50% over a three year period. In the event of an ownership change, utilizationof the NOLs would be subject to an annual limitation under Section 382 determined by multiplying the value of the Company’s stock at theF-19 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) time of the ownership change by the applicable long-term tax exempt rate. The Company has not completed a Section 382 study at this time; however shoulda study be completed certain NOLs may be subject to such limitations. Any future annual limitation may result in the expiration of NOLs before utilization.For the period ended December 31, 2016, 2015 and 2014, the Company has recorded income tax expense of $83,000, $50,000 and $12,000 related touncertain tax positions. The Company’s policy is to recognize potential interest and penalties related to unrecognized tax benefits associated with uncertaintax positions, if any, in the income tax provision. At December 31, 2016 and 2015, the Company had accrued $8,000 and $0 in interest and penalties relatedto uncertain tax positions.The Company is subject to taxation in the United States and various states along with other foreign countries. Due to the presence of net operating losscarryforwards, all of the income tax years remain open for examination by the IRS and various state and foreign taxing authorities. The Company has notbeen notified that it is under audit by the IRS for any of the tax years currently open. The Company is not currently under audit from any state taxingauthorities.The following changes occurred in the amount of unrecognized tax benefits during the years ended December 31, 2016, 2015, and 2014: Year Ended December 31, 2016 2015 2014 (in thousands) Beginning balance of unrecognized tax benefits $167 $117 $105 Additions for current year tax positions 75 50 12 Ending balance (excluding interest and penalties) 242 167 117 Interest and penalties 8 — — Total $250 $167 $117 The amount of income taxes the Company pays is subject to ongoing audits by taxing jurisdictions around the world. The Company’s estimate of thepotential outcome of any uncertain tax position is subject to management’s assessment of relevant risks, facts, and circumstances existing at that time. TheCompany believes that it has adequately provided for these matters. However, the Company’s future results may include favorable or unfavorableadjustments to its estimates in the period the audits are resolved, which may impact the Company’s effective tax rate. The Company does not believe that it isreasonably possible that the total amount of unrecognized tax benefits will significantly increase or decrease in the next 12 months. As of December 31,2016, the Company’s tax filings are generally subject to examination in major tax jurisdictions for years ending on or after December 31, 2012.Deferred income taxes have not been provided for undistributed earnings of the Company’s consolidated foreign subsidiaries because of the Company’sintent to reinvest such earnings indefinitely in active foreign operations.

If the Company was liquidated, dissolved or wound up, or if all or substantially all of the Company’s assets were acquired or if theCompany underwent a change in control, the holders of the Series A and Series A-1 then outstanding would have been entitled to be paid out of theCompany’s assets available for distribution, before any payment was made to the holders of common stock or Class A, the greater of (1) an amount in cashequal to the stated value per share of such holders’ preferred stock plus any accrued but unpaid dividends, whether or not declared, through the date of suchliquidation, sale or change in control or (2) such amounts as such holders would receive if, immediately prior to such liquidation, sale or change in control,the outstanding Series A, Series A-1, and Class A were converted into the Company’s common stock. If the assets or funds available for distribution to theholders of Series A and Series A-1 were insufficient to pay such holders the full amount to which they are entitled, the holders would share prorata in theassets and funds available for distribution, based upon the aggregate value per share of such holders’ preferred stock plus any unpaid dividends, whether ornot declared.Conversion Rights. Each share of preferred stock was convertible at the option of the holder into common stock at a conversion price per share of $2.25 and$2.49 (each subject to adjustments upon the occurrence of certain dilutive events) for Series A and Series A-1, respectively.

The stock options expire ten years after the date of grant.In connection with our IPO, our board of directors resolved not to make future grants under our 2008 Plan. The 2008 Plan will continue to governoutstanding awards granted thereunder.2016 PlanThe Company’s 2016 Equity Incentive Plan, or the 2016 Plan, became effective on September 15, 2016. The 2016 Plan provides for the grant of incentivestock options, non-qualified stock options, restricted stock awards, restricted stock unit awards, stock appreciation rights and performance share awards toemployees, directors and consultants of the Company. A total of 3,893,118 shares of the Company’s common stock were initially reserved for issuance underthe 2016 Plan, which is the sum of (1) 2,000,000 shares, (2) the number of shares reserved for issuance under the 2008 Plan at the time the 2016 Plan becameeffective (up to a maximum of 42,934 shares) and (3) shares subject to stock options or other stock awards granted under the 2008 Plan that would haveotherwise returned to our 2008 Plan (up to a maximum of 1,850,184 shares). The number of shares of common stock reserved for issuance under the 2016 Planwill automatically increase on January 1 of each year, beginning on January 1, 2017, by 3% of the number of shares of the Company’s capital stockoutstanding on the immediately preceding December 31, or such lesser number of shares as determined by the Company’s board of directors. As a result ofthe adoption of the 2016 Plan, no further grants may be made under the 2008 Plan. As of December 31, 2016, there were 2,005,483 shares available for grantunder the 2016 Plan and as of December 31, 2015 there were 232,304 shares available for grant under the 2008 Plan. Stock option awards are granted with anexercise price equal to the fair market value of the Company’s common stock at the date of grant based on the closing market price of our common stock asreported on The NASDAQ Global Market. The option awards generally vest over four years and are exercisable any time after vesting. The stock optionsexpire ten years after the date of grant.Employee Stock Purchase PlanThe Company’s Employee Stock Purchase Plan, or 2016 ESPP became effective on September 15, 2016. A total of 500,000 shares of the Company’s commonstock were initially reserved for issuance under the 2016 Plan. The number of shares reserved for issuance under the 2016 ESPP will automatically increase onJanuary 1 of each year, beginning on January 1, 2017, by the lesser of 200,000 shares of the Company’s common stock, 1% of the number of shares of theCompany’s common stock outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the Company’s boardof directors.The 2016 ESPP allows eligible employees to purchase shares of the Company’s common stock at a discount of up to 15% through payroll deductions of theireligible compensation, subject to any plan limitations. Except for the initial offering period, the 2016 ESPP provides for separate six-month offering periodsbeginning each March and October of each fiscal year.On each purchase date, eligible employees will purchase the Company’s stock at a price per share equal to 85% of the lesser of (i) the fair market value of theCompany’s common stock on the offering date or (ii) the fair market value of the Company’s common stock on the purchase date.For the year ended December 31, 2016, no shares of common stock were purchased under the 2016 ESPP and 83,790 shares are expected to be purchased atthe end of the initial offering period. The Company uses the Black-Scholes option pricing model to measure the fair value of its stock options and thepurchase rights issued under the ESPP. As of December 31, 2016, total recognized compensation cost was $0.2 million and unrecognized compensation costrelated to 2016 ESPP was $0.1 million, which will be amortized over a weighted-average period of 0.25 years. The 2016 ESPP is considered compensatory forpurposes of stock-based compensation expense.F-24 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) Stock OptionsThe weighted-average grant-date fair value per share of options granted for the years ended December 31, 2016, 2015 and 2014, was $14.49, $12.19 and$4.26, respectively. The Company recorded stock-based compensation expense of $3.1 million, $1.5 million and $0.4 million for the years ended December31, 2016, 2015 and 2014, respectively.The total intrinsic value of options exercised in 2016, 2015 and 2014 was $1.6 million, $0.5 million and $1.1 million, respectively. This intrinsic valuerepresents the difference between the fair market value of the Company’s common stock on the date of exercise and the exercise price of each option. Basedon the fair market value of the Company’s common stock at December 31, 2016, 2015 and 2014 the total intrinsic value of all outstanding options was $15.9million, $10.1 million and $5.0 million.There were no excess tax benefits realized for the tax deductions from stock options exercised during the years ended December 31, 2016, 2015 and 2014.The fair value of stock option grants is determined using the Black-Scholes option pricing model with the following assumptions. Year Ended December 31, 2016 2015 2014 Employee Stock Options: Fair value of common stock $14.21 - $18.83 $9.37 - $13.63 $7.02 Expected term (in years) 5.29 - 6.11 5.09 - 6.15 5.89 - 6.13 Expected volatility 60% - 70% 60% 51.7% - 69% Risk-free interest rate 1.21% - 2.55% 1.41% - 1.94% 1.63% - 2.06% Dividend rate 0% 0% 0% Employee Stock Purchase Plan: Expected term (in years) 0.50 — — Expected volatility 60% — — Risk-free interest rate 0.45% — — Dividend rate 0% — — (1)The expected term represents the period that the stock-based compensation awards are expected to be outstanding. Since the Company did not havesufficient historical information to develop reasonable expectations about future exercise behavior, the Company used the simplified method tocompute expected term, which reflects the average of the time-to-vesting and the contractual life;(2)The expected volatility of the Company’s common stock on the date of grant is based on the volatilities of publicly traded peer companies that arereasonably comparable to the Company’s own operations;(3)The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for zero coupon U.S. Treasury notes with maturitiesapproximately equal to the expected term of the options; and(4)The expected dividend yield is assumed to be zero as the Company has never paid dividends and have no current plans to pay any dividends on theCompany’s common stock.Total unrecognized compensation cost, adjusted for estimated forfeitures, related to nonvested stock options was approximately $6.6 million and $6.8million as of December 31, 2016 and 2015, respectively, and is expected to be recognized over a weighted average period of 2.59 years and 1.62 years as ofDecember 31, 2016 and 2015, respectively. The amount of cash received from the exercise of stock options in 2016 and 2015 was $0.8 million and $0.1million, respectively.F-25 Everbridge, Inc.Notes to the Consolidated Financial Statements—(Continued) A summary of activities under the 2008 Plan and 2016 Plan is shown as follows for the years ended December 31, 2016 and 2015: Stock optionsoutstanding Weightedaverageexercise price Outstanding at December 31, 2014 699,662 $2.24 Granted 1,190,317 $12.19 Exercised (37,559) $1.32 Forfeited (30,698) $7.76 Outstanding at December 31, 2015 1,821,722 $8.68 Granted 292,204 $14.75 Exercised (163,968) $4.30 Forfeited (65,533) $8.03 Outstanding at December 31, 2016 1,884,425 $10.02 Stock-based compensation expense is recognized over the award’s expected vesting schedule, which is reduced for estimated forfeitures.
