RIBER presents its financial objectives for 2011-2015

Bezons, May 26th, 2011 –7 am – At its combined general meeting held today, RIBER, the global leader for molecular beam epitaxy (MBE), set out its objectives for the current year and presented its development plan for 2011-2015.

2011: double digit growth in business

Thanks to RIBER's portfolio of orders, it is able to forecast strong growth in its business over 2011. At April 30th, it represented €19.7 million (€9.2 million at the end of April 2010), including certain sales to be delivered after 2011.

In view of the current order book and the performance recorded over the first quarter, revenues are expected to climb to between €27 and €29 million for 2011, enabling RIBER to achieve a further improvement in its profitability.

2015: doubling revenues in relation to 2010

In the MBE Systems business, growth will be driven by the expansion of the commercial offer, made possible by the development of new dedicated systems for research institutes and the semiconductor industry, which is seeing an average annual growth rate of 8%.

The Services and Accessories business will continue to capitalize on the installed base of 800 systems, combined with growth in epitaxy equipment sales and the development of activities in emerging countries. Sales are expected to grow 40% by 2015.

The diversification into the OLED (Organic LED) and thin-layer solar cell (CIGS technology) markets which look set for strong growth is also expected to support RIBER's sales and consolidate its position as a high value-added equipment manufacturer.

Looking ahead to 2015, RIBER is targeting €40 million in revenues (compared with €20.7 million in 2010).
