Everbridge Announces Critical Event Management and Acquisition of IDV Solutions

IDV’s Threat Assessment and Operational Visualization Solution to Become Part of Industry’s First Integrated Software Platform for Managing Critical Events

Burlington, Mass. – January 31, 2017 – Everbridge, Inc. (NASDAQ: EVBG), a global software company that provides critical communications and enterprise safety applications to help keep people safe and businesses running, today announced that it has acquired IDV Solutions, LLC, a leading provider of threat assessment and operational visualization software. IDV’s powerful Visual Command Center® (“VCC”) application displays an integrated picture of external threats and events overlaid with an organization’s people, assets and supply routes, along with other contextual information to enable timely assessment and operational response. In combination with Everbridge’s critical communication, incident management and employee safety capabilities, IDV’s VCC application will form a key component of the industry’s first Critical Event Management™ (CEM) platform for dynamically assessing, responding to, and managing the resolution of the wide range of threats and disruptions which impact organizations’ daily operations.

IDV Solutions transforms an organization’s situational intelligence and operational visibility during a critical event. The VCC application enables customers to monitor and integrate more than 100 types of threat data, as well as information on internal incidents, to generate and visualize an alert when potential risks occur within proximity of an organization’s physical locations, suppliers, assets and people. The solution improves the ability to more quickly understand and assess the impact of threats, execute the correct response, and monitor on-going resolution in order to mitigate risk to personnel safety, business continuity, assets and supply chain operations. The highly visual and intuitive VCC solution is used by global distribution companies such as Amazon, leading technology companies such as Dell and VMware, pharmaceutical giants such as Pfizer, major retailers such as Tiffany & Company, large energy companies such as Noble Energy, supply chain leaders such as XPO Logistics, and government entities such as St. Clair County in Michigan.

IDV has been an Everbridge strategic partner since 2014. Everbridge’s global, multi-modal communication capabilities enhance VCC’s ability to help companies take action based upon identified risks, and Everbridge’s Safety Connection® application will enable users of VCC to more dynamically locate people who may be at risk, or can respond to an incident.

Industry’s First Critical Event Management (“CEM”) Platform Everbridge is integrating its market leading critical communication, incident management (enhanced by the previously announced Crisis Commander acquisition) and employee safety capabilities with the threat assessment and visualization capabilities of the VCC application to create the industry’s first CEM platform. Everbridge’s CEM is designed to provide organizations with a single platform for managing the full array of intelligence, coordination and task execution items required to speed the response to the many critical incidents that impact daily operations, including severe weather, terrorism, workplace violence, IT outages and cyberattacks, supply chain disruptions, product recalls, environmental accidents or power outages. The annual cost of these types of events exceeded $535 billion in 2015, and they are complex to assess, manage and mitigate.

CEM will provide organizations with a more integrated operational approach to the often disparate systems used today to manage major incidents and IT operations events by delivering an end-to-end view integrating threats, operational impact and response status information on a “single pane of glass.” CEM is intended to enable corporate and government organizations to consolidate overlapping systems and drive cost efficiencies, as well as to improve response time, minimize disruption, and attain better management control in handling critical events. The CEM platform will also integrate with leading Governance, Risk and Compliance (GRC) as well as Business Continuity Planning (BCP) solutions.

“Many of our over 3,000 corporate and government customers have told us that they are spending hundreds of thousands of dollars supporting separate command centers for security, IT, and supply chain operations, and yet they still struggle to manage the increasing number of critical events affecting their enterprises,” said Jaime Ellertson, CEO, Everbridge. “We believe CEM can provide a unified understanding of these critical events through a common platform that will enable a higher level of situational intelligence and collaboration, ultimately reducing the cost and overall impact to operations.”

“Leveraging Everbridge’s deep and complementary technical capabilities will enhance our ability to provide even more strategic value and expertise to our customers,” said Mark Morrison, CEO, IDV Solutions. “The ability to combine security, supply chain and IT operations threats and incidents in one common view, ensure all the relevant stakeholders are informed and receive feedback from them, have continuous visibility into the status of remediation, and analyze team performance over time to identify bottlenecks and make improvements will greatly enhance the impact of our current solutions.”

Financial Information The aggregate consideration paid by Everbridge was approximately $18.7 million in cash, with additional time and performance-based cash payments that could total as much an additional $8.7 million. Everbridge will provide specific information on the expected impact of the acquisition on Everbridge’s financial results after completing its purchase accounting review. In addition, as previously announced, Everbridge will report its fourth quarter and full year 2016 financial results on February 27, 2017, at which time it will also provide guidance for its business for the first quarter and full year 2017.
