Expiration date of Nokia’s public buy-out offer for Alcatel-Lucent securities extended following a legal action against AMF clearance decision; squeeze-out to follow completion of public buy-out offer

Espoo, Finland — The French stock market authority (Autorité des marchés financiers, “AMF”) announced today that a legal action was filed before the Paris Court of Appeal on September 30, 2016 for annulment of the AMF’s clearance decision regarding Nokia’s public buy-out offer (the “Public Buy-Out Offer”), which would be followed by a squeeze-out (the “Squeeze-Out”, together with the Public Buy-Out offer, the “Offer”), for all remaining securities of Alcatel-Lucent. Consequently, the Public Buy-Out Offer period is extended until further notice and the Squeeze-Out, which had been scheduled for October 6, 2016, will take place once the public buy-out offer is completed.

Nokia is now awaiting details of the legal action, and the AMF will publish a further notice with a new timetable in due course. Nokia believes that the Offer complies with all applicable laws and regulations and expects that, unfortunate delay aside, the legal action will not have a material impact on its acquisition of the remaining outstanding securities of Alcatel-Lucent.

Documentation relating to the Offer, which includes Nokia and Alcatel-Lucent’s joint offer document (note d’information conjointe) and Nokia’s and Alcatel-Lucent’s respective “other information” documents, is available on the AMF website (www.amf-france.org), on Nokia’s website (http://company.nokia.com/en/investors/financial-reports/filings-related-to-the-alcatel-lucent-transaction), and on Alcatel-Lucent’s website (www5.alcatel-lucent.com).
