During the first quarter of fiscal 2011, Siemens and Origin S.A. (“Atos”) signed an option agreement which grants Atos the right to acquire Siemens IT Solutions and Services in exchange for 12.5 million newly issued shares in Atos with a five-year lock-up commitment, a five-year convertible bond of €250 million and a cash payment of €186 million with a total value of €850 million at the time of announcement. The final value of the consideration will depend on the price of Atos shares and the bond value at closing. Furthermore, Siemens will provide extensive support in order to foster the company’s business success including, among others, up to €250 million to the integration and training costs and further protections and guarantees. Related to the transaction is a seven-year outsourcing contract worth around €5.5 billion, under which Atos would provide managed services and systems integration to Siemens. On February 1, Atos exercised the option and signed a final binding agreement to acquire Siemens IT Solutions and Services. Pending certain closing conditions, including receipt of the necessary approvals from regulatory authorities and governing bodies of Atos, closing of the transaction is expected in the fourth quarter of fiscal 2011.
