Evolving Systems Acquires Telespree Communications, Gaining Cloud-Based Activation Platform

Expands DSA Solution with Complementary SaaS Service Enablement and Accelerates Momentum into US Market

ENGLEWOOD, Colorado — Evolving Systems, Inc. (NASDAQ: EVOL), a leading provider of activation-based solutions to telecom operators worldwide, today announced it has acquired privately held Telespree Communications, a SaaS provider of service activation, self-service mobile applications and data enablement solutions to wireless carriers and MVNOs.  Telespree is based in San Francisco, CA.

Highlights of the acquisition include:

·                  Telespree’s customer base is comprised entirely of US-based carriers and MVNOs with over 50% of revenue derived from a tier-1 wireless carrier.  This complements Evolving Systems’ overseas customer base and provides the Company with significant expansion opportunities in North American markets.

·                  Telespree’s cloud-based service activation and mobile broadband enablement solutions are ideal extensions to Evolving Systems’ Dynamic SIM Allocation™ (DSA) solution. Telespree’s deep experience with SaaS solutions, which account for 100% of its revenue, will provide Evolving Systems with immediate benefits as the Company prepares to introduce a SaaS version of its DSA solution. Telespree will also augment Evolving Systems’ expertise in the areas of Android and iOS mobile app development and turnkey platform development.

·                  Through Telespree’s Dataspree Control Solutions, Evolving Systems  will accelerate and expand its solutions for the connected device and M2M markets.

·                  Telespree holds 11 US patents — seven of which have relevance to SIM cards and Evolving Systems’ DSA solution — which further strengthens the Company’s growing IP portfolio. Evolving Systems recently was granted its fourth US patent on elements of its DSA solution.

“Telespree’s production-proven SaaS-based activation solutions and US customer base are great additions to Evolving Systems. Specifically, Telespree’s unique mobile broadband service enablement SaaS platform — offered to both LTE and 3G carriers — as well as their M2M cloud solution will position us to capitalize on demand in both domestic and international markets,” said Thad Dupper, Chairman and CEO of Evolving

Systems. “Our acquisition of Telespree supports our strategic plans to offer SaaS as well as premise-based solutions and continues our transition to more of a recurring revenue business model.”

“We are excited about joining Evolving Systems,” said Ellen Schwab, CEO of Telespree. “Our product portfolio and SaaS expertise are extremely complementary to Evolving Systems’ operations and we look forward to working with their team to offer these solutions internationally. I am also confident, given the synergy between the two companies, that the combined teams will continue to develop and deliver innovative, industry leading solutions worldwide.”
