Nokia has filed its draft public exchange offer document with the French stock market authority relating to the proposed public exchange offer to acquire Alcatel-Lucent

The information contained in the draft public exchange offer document filed with the French stock market authority (Autorité des marchés financiers, “AMF”) on October 29, 2015 is preliminary and incomplete and the draft is subject to future amendments. Please note that the statements in the draft public exchange offer document are presented as of the date of filing of the proposed public exchange offer. Nokia may not commence the public exchange offer until the draft public exchange offer document has been reviewed and cleared by the AMF.

Espoo, Finland — Nokia today announced that it has filed its draft public exchange offer document (note d’information) with the AMF relating to the proposed public exchange offer. As previously announced, Nokia intends to acquire all ordinary shares, American depositary shares (“ADSs”) and convertible bonds (“OCEANEs”) issued by Alcatel-Lucent through a public exchange offer in France (the “French Offer”) and in the United States (the “U.S. Offer”) whereby Alcatel-Lucent securities will be exchanged for Nokia shares in the French Offer and Nokia shares or Nokia ADSs in the U.S. Offer (jointly, the “Exchange Offer”).

Nokia expects to open the Exchange Offer in the second half of November 2015, following the review and clearance of the proposed public exchange offer by the AMF. Once the Exchange Offer period opens, the proposed transaction will remain subject to approval by Nokia shareholders and the satisfaction of the minimum tender condition set at more than 50% of Alcatel-Lucent’s share capital on a fully diluted basis, unless such condition is waived in accordance with applicable law and regulation.

Information disclosed in the draft public exchange offer document

The information contained in the draft public exchange offer document filed with the AMF is preliminary and incomplete and the draft is subject to future amendments before being cleared by the AMF. The draft public exchange offer document includes more detailed information on the terms of the proposed French Offer. A copy of the draft public exchange offer document is posted on Nokia’s website at http://company.nokia.com/en/investors/financial-reports/filings-related-to-the-alcatel-lucent-transaction.

In the draft public exchange offer document, Nokia is providing, among others, the following information not previously disclosed.

Terms of the Exchange Offer

As previously disclosed, Nokia is offering a consideration of 0.5500 Nokia shares in exchange for each Alcatel-Lucent share and Alcatel-Lucent ADS and such number of Nokia shares in exchange for one OCEANE that is based on the exchange ratio of 0.5500 Nokia shares per each Alcatel-Lucent share which would be issuable upon conversion or exchangeable upon exchange of the OCEANE at the conversion/exchange ratio which will apply on the opening date of the Exchange Offer.

The precise offer price for the OCEANEs cannot be determined until the opening date of the Exchange Offer has been established, but preliminarily, Nokia is offering to exchange the Alcatel-Lucent OCEANEs for Nokia shares under the following exchange ratios (based on the expected opening date of November 18, 2015):

·                                          0.6930 Nokia share for one tendered Alcatel-Lucent 2018 OCEANE;

·                                          0.7040 Nokia share for one tendered Alcatel-Lucent 2019 OCEANE; and

·                                          0.7040 Nokia share for one tendered Alcatel-Lucent 2020 OCEANE.

Timetable of the Exchange Offer

The timetable for the French Offer is subject to approval by the AMF, but based on an indicative timetable and assuming that the AMF clearance decision would be received on November 12, 2015, the French Offer would be opened on November 18, 2015, closed on December 22, 2015 and settled on January 7, 2016. Assuming that the Exchange Offer is successful, the French Offer would be reopened on January 14, 2016, close on February 3, 2016 and settle on February 12, 2016. The timetable for the U.S. Offer is expected to follow that of the French Offer.

Recommendation by the Board of Directors of Alcatel-Lucent published and draft response document filed

The information contained in the draft response document filed by Alcatel-Lucent with the AMF is preliminary and incomplete and the draft is subject to future amendments before being cleared by the AMF. A copy of the draft response document is posted on Alcatel-Lucent’s website at https://www.alcatel-lucent.com.

Alcatel-Lucent has today announced that its Board of Directors has unanimously determined that Nokia’s public exchange offer is in the best interest of Alcatel-Lucent, its employees and its stakeholders (including holders of Alcatel-Lucent shares and holders of other Alcatel Lucent securities) and recommended that all holders of Alcatel-Lucent shares, ADSs and OCEANEs, respectively, tender their Alcatel-Lucent securities pursuant to the Exchange Offer. Alcatel-Lucent’s Board of Directors made its decision on the basis of a number of factors further detailed in Alcatel-Lucent’s draft response document (note en réponse) filed with the AMF today, which include, inter alia, the report issued by Associés en Finance, acting as independent expert in connection with the French Offer which concluded that the terms of the public exchange offer by Nokia on Alcatel-Lucent’s shares and OCEANEs are fair.
