POSITIVE ACHIEVEMENTS

> Good business momentum- 11 new customers (excluding GYPRO®)- Further penetration of new markets

(Life Sciences)

> Acceleration of international development

> Ramp up of activity at Dallas

> Strengthening of inertial product range GYPRO® and AXO

> Significant investments for the development of new products

DIVERSIFICATION OF CUSTOMER PORTFOLIO

STRENGTHENING AT INTERNATIONAL LEVEL

… AND FACTORS THAT WEIGHED ONPROFITABILITY

> No revenue from the historical customer of the Group (vs €1.8M in 2014) in an unfavourable oil environment

> Volume of manufacturing orders lower than expected at the beginning of the period (optical, RF MEMS)

> Finalisation of an engineering project with high added value postponed to 2016

> Longer timeframes than expected between engineering phase and production launch

LAUNCH OF A €700K COST REDUCTION PLAN AT THE

END OF 2015, EFFECTIVE IN 2016
