STALLERGENES (Paris:GENP):

Not for release, directly or indirectly, in South Africa, Australia, Canada, Japan, New Zealand or the United States of America

Strong growth in H1 2015 sales in all geographic regions

Sales for the first half of 2015 totalled €141.3 million, an increase of 8.7% compared with the first half of 2014.

Over the first half year, the "Southern Europe” region saw steady growth of 7.8%, driven by the continued success in France of the new dosing pump for the sublingual solutions treatment Staloral^®. The "Northern and Central Europe” region achieved growth of 3%, thanks to Poland, where Stallergenes has become the market leader, and Switzerland, where the Oralair^® tablet has enjoyed strong growth. Due to the continued progress of Staloral^®, a positive trend was seen in the UK, which remains an underdeveloped market.

Outside Europe, international markets performed well (up 33.8%), notably in Russia, due to the significant increase in the number of patients receiving allergen immunotherapy, and in Australia, where the sublingual segment grew strongly. In Canada, the affiliate created in late 2014 has yielded very encouraging initial results. In the United States, sales of Oralair^® to our US partner GREER LABORATORIES Inc. grew to €0.8 million over the first half.

All routes of administration and sales related to the main allergens on the increase

The sublingual route rose 9% over the half year, thanks notably to Oralair^® which continued its growth. With a 13.2% increase in first half sales in comparison with the same period the previous financial year, Oralair^® performed well in France, Germany, Switzerland and the Czech Republic.

The segments for the three main allergens (house dust mites, grass pollen and birch pollen) all grew, up 12.9%, 7.5%, and 10.1% respectively.

The project to combine STALLERGENES and GREER LABORATORIES Inc. approved by the Shareholders' General Meeting

At the General Meeting of 26 June 2015, STALLERGENES' shareholders approved the transaction to combine the activities of STALLERGENES with those of GREER Laboratories in order to form the global leader in allergen immunotherapy¹.

According to the current timetable, the transaction will take effect in September 2015, following completion of all the legal formalities required for its implementation.

Following completion of the transaction, STALLERGENES’ and GREER’s activities will be held by Ares Allergy Holdings PLC, UK subsidiary of Ares Life Sciences, whose shares will be listed on the Euronext Paris regulated market.
