Overview

Xura was the communications-technology brand adopted by the combined Comverse and Acision businesses in September 2015. The company operated in the business-to-business telecommunications market, selling software, cloud services, and professional and managed services to communications service providers and enterprise customers. Its portfolio addressed digital communications, messaging, traditional and Internet-protocol-based value-added services, communications applications, policy and monetization functions, and security. The business had roots in Comverse, a communications-software company that had previously operated within Comverse Technology. Comverse Network Systems was incorporated in the United States in 1997 as part of that wider holding company. A restructuring announced in 2012 and completed in February 2013 separated Comverse from Comverse Technology, which was effectively liquidated as an operating holding entity. The independent Comverse business was led by Philippe Tartavull and continued developing systems for telecommunications operators. Comverse's activities included business-support systems, policy-control technologies such as policy and charging enforcement functions, traditional value-added services, IP communications, cloud business voice, unified communications, and related professional services. In June 2015, Comverse divested its business-support-systems operation to Amdocs. In August of the same year, it completed the acquisition of Acision, a company focused on mobile messaging, communications engagement, and related security capabilities. The combination provided the basis for the Xura identity. Xura was launched as the new brand of the combined company on September 9, 2015. The name was described as an adaptation of “Aura,” and the company stated that Comverse and Acision subsidiaries would also be renamed. Under Tartavull, Xura presented itself as a provider helping service providers and enterprises navigate and monetize the digital communications ecosystem. Its stated customer reach extended to more than 350 service providers and enterprises in more than 100 countries, although the available reference material does not provide a detailed revenue breakdown. The Xura portfolio was organized around digital communications and converged communications. Offerings included communications suites, messaging infrastructure, call-completion services, network-signaling and messaging security, low-credit services, advanced value-added services, white-label communications applications such as fuseMe, secure communications, and the forge framework for rich web and mobile application development. These products were intended to help operators launch communications services, improve customer engagement, manage network and messaging traffic, and create new monetization opportunities. Xura was publicly traded under the symbol MESG until its acquisition by affiliates of Siris Capital Group. In May 2016, the parties announced an all-cash transaction valued at approximately $643 million, based on an offer of $25 per share. The transaction closed on August 19, 2016, taking Xura private. Hubert de Pesquidoux, an executive partner of Siris Capital, became executive chairman. The privately backed company then pursued further expansion. In December 2016, Xura affiliates agreed to acquire Mitel Mobility, a division of Mitel Networks, for $385 million, and Ranzure Networks, an early-stage company working on cloud-based 5G radio-access-network technology, for an undisclosed amount. The Mitel Mobility and Ranzure transactions closed in February 2017. Xura was subsequently subsumed into a new entity known as Mavenir, ending Xura as a standalone corporate brand.

History

Xura emerged from the restructuring of Comverse Technology and the subsequent combination of Comverse with Acision. Comverse had operated for many years as part of Comverse Technology, whose businesses included communications and related technology activities. Comverse Network Systems was incorporated in the United States in November 1997. In 2012, transactions were announced to unwind Comverse Technology as a functioning holding company. Those transactions were completed by February 2013, leaving Comverse as an independent company led by Philippe Tartavull. The independent Comverse business supplied telecommunications software and services, including business-support systems, policy-control functions, value-added services, cloud business voice, unified communications, and professional and managed services. Its customers were principally communications service providers and other organizations operating communications networks. In June 2015, Comverse sold its business-support-systems business to Amdocs. This divestment narrowed the company's focus while allowing it to concentrate on digital communications and related network and customer-engagement capabilities. In August 2015, Comverse completed its acquisition of Acision, a privately held company associated with secure mobile messaging and communications engagement. The combined organization launched the Xura brand on September 9, 2015. Xura described the new identity as deriving from the word “Aura” and announced that the former Comverse and Acision subsidiaries would be renamed. Its commercial proposition centered on helping operators and enterprises create, manage, secure, and monetize digital communications services. Xura's portfolio covered three broad areas: digital communications, messaging infrastructure, and converged communications. Products and services included communications suites, call-completion capabilities, network-signaling security, messaging security, low-credit services, advanced value-added services, enterprise communications applications, secure communications, and development tools for web and mobile applications. The company also supported traditional and IP-based value-added services and offered cloud and managed-service models. Reference material states that its solutions were used by more than 350 service providers and enterprises in over 100 countries. Xura was listed on the NASDAQ exchange under the ticker MESG until its acquisition by affiliates of Siris Capital Group. Announced in May 2016 and completed on August 19, 2016, the transaction was an all-cash purchase at $25 per share with an indicated value of approximately $643 million. Xura became privately held, and Hubert de Pesquidoux, a Siris Capital executive partner, became executive chairman. The post-acquisition company continued pursuing consolidation and technology expansion. In December 2016, affiliates agreed to acquire Mitel Mobility, a Mitel Networks division, for $385 million, as well as Ranzure Networks, an early-stage developer focused on cloud-based 5G radio-access-network technology. Both transactions completed in February 2017. Xura was then subsumed into a new Mavenir entity, ending the independent Xura corporate identity.
