KEY FIGURES AND EVENTS AT SEGMENT LEVEL

IBA reported the following segmental trends and news during the first quarter of 2015:

Proton Therapy and Other Accelerators

• At the end of the first quarter, the segment reported revenues of EUR 44.0 million, compared to EUR 33.1 million for the same period in 2014
• In demonstration of the continuing strength of the proton therapy market, IBA again reported a record backlog in Proton Therapy and Other Accelerators amounting to EUR 278.8 million for the first quarter of 2015
• IBA's proton therapy pipeline also remains very strong and the Company is currently working on tenders and opportunities totalling in excess of EUR 1 billion, with growing international demand both for the compact solution Proteus®ONE and Proteus®PLUS
• In 2014, IBA and Philips joined forces to collaborate on sales, marketing, research and development of imaging and therapy solutions in oncology. This collaboration is progressing well with promising prospects being generated in several key markets, as well as good progress on the technical aspects of the collaboration
• Post the period end, IBA was delighted to secure another strategic partnership, this time with Toshiba giving IBA broader access to the Japanese market for its Proteus®ONE system, as well as greater exposure to carbon therapy treatment which has the potential to be a complimentary treatment to proton therapy in the future

Dosimetry

• The backlog at the end of the first quarter amounted to EUR 17.4 million compared with a 16.8 million backlog end of 2014
• Two important multi-year tender won for Venezuela and Brazil showing competitiveness of IBA Dosimetry solutions.

Discontinued Operations

On April 17th IBA announced that Illinois Health and Science (IHS), a non-profit healthcare system, had signed a definitive agreement with IBA Molecular (IBAM), a joint-venture jointly owned by IBA and SK Capital Partners, to acquire IBA Molecular North America, Inc. (IBAM NA), the US subsidiary of IBA Molecular, subject to financing. It is not expected to have a significant financial impact on IBA's 2015 profit and loss statement

OUTLOOK

IBA reiterates its guidance given at the time of the Company's 2014 Full Year Results in March 2015. From 2015 to 2018, IBA expects to achieve average revenue growth greater than 10% per annum. The Company expects its operating margin to stabilize at 10% in 2015 and then grow at 1% per annum until 2018. Net debt is expected to stay limited over the course of the years to come. Due to the necessary continued investments in technological advances in proton therapy to maintain leadership in the space, IBA is planning a dividend payout ratio of 20% in 2015 based on 2014 results, but it is the Company's intention that if market conditions prevail, the dividend should gradually reach a payout ratio of 30% in the future.
