PARIS — (BUSINESS WIRE) — June 4, 2015 — Alain de Rouvray, ESI Group’s (Paris: ESI) Chairman and CEO, comments: "First quarter revenue, entirely achieved on an organic basis, rose nearly 20% compared to the same period last year. This strong and balanced growth was helped by favorable currency effects. Such very good performance, in line with our expectations, attests to the solid sales momentum at the beginning of the fiscal year across all our business activities. In addition, our Licenses activity showed an especially high rate of repeat business on the installed base, and grew in every geographic area. At the same time, the Services activity achieved a growth of nearly 18% after our successful refocusing on high value-added projects, demonstrating the exceptional value of our Virtual Prototyping predictive solutions. Our disruptive offer enables simultaneous multi-domain optimization all the way to the virtual pre-certification of our customers’ innovative products. The continued rollout of our virtual engineering products, combined with our recent, future-oriented acquisitions, gives us confidence in the success of our short- and medium-term corporate development plans."
