West Monroe Partners Acquires Salesforce.com CRM Consulting Business

MINNETONKA, Minn., Oct. 26, 2015 — Digi International^®, (NASDAQ: DGII, www.digi.com), a leading global provider of mission-critical machine-to-machine (M2M) and IoT connectivity products and services, today announced the sale of Etherios, a leading Salesforce implementation partner. West Monroe Partners, a full-service North American business and technology consultancy, purchased Etherios for US$9 million in cash payable US$4 million at closing, US$3 million on the first anniversary of closing and US$2 million on the second anniversary of closing.

Etherios is a professional services firm and Salesforce Platinum Partner focused on delivering cloud-based sales excellence solutions specifically tailored for the Salesforce platform. The divestiture of Etherios allows Digi International to improve its focus on providing highly reliable machine connectivity solutions for business-critical and mission-critical application environments.
