In addition to these sales of instruments and services, the order book at March 31, 2009 amounted to

1,355 M€, compared to 1,310 M€ one year earlier.

After a slow start to the year, sales picked up significantly in line with expectations during the

second quarter. However, for the half year taken as a whole, which historically represents 35-

40% of annual sales, growth was limited to 13,9%, which is below our expectations. It should be

noted that Périchrom was not consolidated for the first half 2007-08.

High added-value service and engineering revenues performed strongly (+ 43.8%) over the

period thanks to the growth of the customer base and the emphasis on long-term development

projects. Geographically, Asia was commercially dynamic whereas the European and US markets

remained morose. The opening of a new subsidiary in Japan in April will allow the group to

capitalize on the enormous potential within this market. The majority of sales by segment

continued to be in the food and environmental sectors, which are at the heart of the Group’s

development and commercial strategy.

According to Jean-Christophe MIFSUD, CEO of Alpha Mos, « We are satisfied with the

reaction observed during the second quarter and the strength of the order book in the face of a

difficult economic climate. However, even if the commercial outlook for the second half-year is

good, the profitability of the Group will be lower than expected, adversely affected by the level

of investment made at the end of last year and the beginning of 2009.

We will continue to promote and sell our technology, looking to exploit those sectors which

appear the most promising in the short term while at the same time bringing into line our

operating structure and level of fixed costs. We will continue to work on the important

opportunities for high volume and value sales already identified but for which the lead-times are

more difficult to ascertain in the current climate of affairs».

Full audited results for the first half year will be published on May 29, 2009.
