Nokia to issue convertible bonds of EUR 1.5 billion to Microsoft

Nokia Corporation

Stock exchange release

September 6, 2013 at 18.40 (CET+1)

Espoo, Finland — On September 3, 2013 Nokia announced that, in connection with its announcement to sell to Microsoft Corporation substantially all of its Devices & Services business (the “Sale of the D&S Business”), Microsoft had agreed to make available to Nokia EUR 1.5 billion of financing in the form of three EUR 500 million tranches of convertible bonds.

Today, Nokia announces that it has decided to draw down all of this financing and thus Nokia will issue three tranches of senior unsecured convertible bonds, each with a nominal value of EUR 500 million (the “Bonds”). Nokia’s Board of Directors decided today to issue the Bonds on the basis of the authorization granted by the Annual General Meeting of Nokia held on May 7, 2013.

Nokia intends to use the proceeds of the offering to prepay financing raised for the acquisition of the shares in NSN which was completed in August 2013 and for general corporate purposes.

The key terms of the Bonds to be issued are as follows:

· The first tranche (the “2018 Bonds”) matures in 5 years and has a 1.125% per annum coupon payable semi-annually with an initial conversion price of EUR 3.9338.

· The second tranche (the “2019 Bonds”) matures in 6 years and has a 2.5% per annum coupon payable semi-annually with an initial conversion price of EUR 4.0851.

2

· The third tranche (the “2020 Bonds”) matures in 7 years and has a 3.625% per annum coupon payable semi-annually with an initial conversion price of EUR 4.2364.

If the Sale of the D&S Business is completed, the Bonds will be redeemed and the principal amount and accrued interest netted against the Sale of the D&S Business proceeds.

All the Bonds are issued at par and will be redeemed at par on the closing date of the Sale of the D&S Business. Should the Sale of the D&S Business not be completed, the Bonds will be redeemed at par on their respective maturity dates, unless otherwise redeemed, purchased, converted or cancelled in accordance with their terms.

The Bonds are expected to be issued on or about September 23, 2013.

Microsoft has agreed not to sell any of the Bonds or convert any of the Bonds to Nokia shares prior to the closing of the Sale of the D&S business.

Should the Sale of the D&S Business not be completed, Microsoft would have the right to sell the 2018 Bonds immediately. Microsoft has agreed not to sell any of the 2019 Bonds prior to the second anniversary of their issuance date and any of the 2020 Bonds prior to the third anniversary of their issuance date.

Microsoft has also agreed not to convert any of the 2018 Bonds and any of the 2019 Bonds into Nokia shares prior to the second anniversary of their issuance date and for the 2020 Bonds prior to the third anniversary of their issuance date, except in a change of control situation. Thereafter, the conversion right continues until the date falling seven business days prior to the maturity date of the relevant bond. If the Bonds are converted into Nokia shares by Microsoft, Microsoft has agreed to vote according to recommendations of Nokia’s Board of Directors, save in circumstances where this would be construed as Microsoft acting in concert with Nokia for purposes of the Finnish Securities Markets Act.

3

Nokia has the right to redeem all outstanding 2018 Bonds and 2019 Bonds after the third anniversary of their issuance date plus 30 days if the volume weighted average price of the Nokia shares is at least 130% of the then prevailing conversion price for a specified period of time, and with respect to the 2020 Bonds Nokia has a similar right after the fourth anniversary of their issuance date plus 30 days. Nokia will also have the right to redeem each tranche of Bonds at any time if conversion rights are exercised and/or purchases (and corresponding cancellations) and/or redemptions are effected in respect of 85% or more in principal amount of such tranche of Bonds. The terms and conditions of the Bonds provide for adjustments of the then applicable conversion price for any dividends in cash or in kind as well as customary anti-dilution adjustments.

Nokia will make an application to include the Bonds for trading on the Open Market (Freiverkehr) segment of the Frankfurt Stock Exchange as soon as reasonably practicable following the issuance date of the Bonds.

The maximum number of shares which may be issued by Nokia upon conversion of all the Bonds (based on the initial conversion price of each tranche) is approximately 367.5 million, representing approximately 8.9 % of Nokia’s shares as calculated based on current amount of shares added with shares to be issued upon conversion of all the Bonds.

Stock exchange release

September 6, 2013 at 18.45 (CET+1)

Espoo, Finland — Nokia has on September 6, 2013 received a flagging notification in accordance with Chapter 9, section 5 of the Finnish Securities Markets Act from Microsoft Corporation. As announced on September 3, 2013 Microsoft has made available to Nokia EUR 1.5 billion financing in the form of convertible bonds to be issued by Nokia. Each tranche is of nominal value of EUR 500 million maturing in 2018 (“2018 Bond”), in 2019 (“2019 Bond”) and in 2020 (“2020 Bond”), respectively. The financing is provided by Microsoft International Holdings B.V., an indirectly wholly owned subsidiary of Microsoft Corporation. Nokia has on September 6, 2013 decided to draw down the facility and the three tranches of convertible bonds will be issued on or about September 23, 2013.

If the transaction announced on September 3, 2013 by which Microsoft is expected to purchase substantially all of Nokia’s Devices & Services business would not close and all the convertible bonds were converted into shares of Nokia this arrangement could lead to Microsoft International Holdings B.V.’s holdings in Nokia to be altogether 367 524 324 shares and voting rights, representing 8.9 % of all the shares and voting rights in Nokia as calculated based on current amount of shares added with shares from conversion of all the above bonds.  The 2018 Bond could be converted into 127 103 563 shares and votes, the 2019 Bond into 122 396 024 shares and votes and 2020 Bonds into 118 024 737 shares and votes.

At closing of the sale of substantially all of Devices & Services business, announced on September 3, 2013, Nokia shall buy and  Microsoft International Holdings B.V.  shall sell the bonds at the closing and the nominal value of the bonds plus accrued interest will be netted against the proceeds from the sale.

Microsoft International Holdings B.V. has committed not to convert the 2018 Bonds and 2019 Bonds into shares of Nokia until the second anniversary of the issuance date of the bonds and 2020 Bonds until the third anniversary of the issuance date of the bonds. Thereafter, the conversion right continues until the date falling seven business days prior to the maturity date of the relevant bond. If the bonds are converted into Nokia shares Microsoft International Holdings B.V. has committed to vote in accordance with the recommendations of Nokia’s board of directors, except when it would be deemed to be acting in concert with Nokia pursuant to the Finnish Securities Markets Act.

Microsoft International Holdings B.V. (tax ID: 17103708) has its head office in Netherlands and is a indirectly wholly owned subsidiary of Microsoft Corporation (Tax ID: 600413485).

The current number of shares and voting rights in Nokia is 3 744 994 342. Should all the convertible bonds be converted into shares in Nokia, the number of shares and votes would increase to 4 112 518 666 (assuming that no other new shares would have been issued by Nokia).
