JORMA OLLILA, CHAIRMAN AND CEO:

I was pleased to see strong year-on-year sales growth for the third quarter in a row. Our overall sales growth of 18% was accompanied by an increase in net profit of 29% and resulting in EPS growth of 33%. Profitability was driven by an excellent performance from our device businesses. This was backed by growing strength in our product portfolio and our ability to manage costs and execute well.

Overall industry volume growth for the third quarter continued to exceed our expectations at 199 million units. We have again raised our full year market estimate to approximately 780 million units. Our own third-quarter volumes grew to a record 66.6 million units.

We saw growth in our market share, which reached an estimated 33%, up from 32% in the third quarter last year and stable sequentially. We continued to gain share both sequentially and year on year in China and Asia Pacific, while our share in Europe/Middle East/Africa was stable sequentially and grew year on year. In Latin America and to a lesser extent North America our market share declined sequentially.

As we indicated in July, profitability in our Networks business during the third quarter continued to be under pressure. This was largely due to the combined effects of a fiercely competitive market, our investments into building a presence in the growing network services market and our ongoing push into new growth markets.

In mobile devices, we have been making excellent progress in expanding and upgrading our product offering, which is the broadest in the market and caters to all relevant consumers and trade customers globally. Recent launches include mobile devices for business users, a fold phone targeting high-growth markets, music-optimized phones, and even a fashion collection. Earlier this summer, we also sold our one billionth mobile phone – a Nokia 1100 in Nigeria.

INDUSTRY DEVELOPMENTS AND NOKIA Q4 OUTLOOK

Based on volume developments during the third quarter 2005, Nokia now expects the overall mobile device market for the full year to reach approximately 780 million units, compared with our previous estimate of 760 million units, and up from an estimated 643 million units in 2004. Industry volumes in the fourth quarter 2005 are expected to reflect the usual holiday seasonality and grow compared with the third quarter 2005.

Nokia mobile device volume growth is expected to exceed overall market growth in the fourth quarter, with Nokia’s market share expected to increase both year on year and sequentially.

Industry volume growth is expected to come primarily from an expanding mobile subscriber base in developing markets, where Nokia believes it has a strong volume advantage backed by its brand, quality and broad distribution presence. In more developed markets, replacement and upgrade sales continue to be driven by the availability of new features, services and cameras. Nokia continues to expand and upgrade its portfolio of mid- and high-end devices to capitalize on this.

We expect Nokia’s average selling prices in the fourth quarter to decline sequentially. This is primarily because mobile device volumes from Latin and North America, where low-end products predominate, are expected to represent a significantly higher proportion of Nokia’s overall device volumes in the fourth quarter, compared with the third quarter.

In mobile infrastructure, Nokia now expects the overall market in 2005 to show slight to moderate growth compared with 2004 in euro terms. Operators in developing countries are at various stages of acceleration in their capacity upgrades to meet rising subscriber growth, while in advanced markets, there is ongoing targeted investment in capacity and network optimization. Nokia expects its own networks sales to be down year on year when compared to the exceptionally strong sales generated by operator year-end spending in the fourth quarter of 2004, but also due to the fact that a significant amount of operators’ current investment is taking place in markets were Networks has not historically had a major presence, such as the Middle East and Africa.

Q3 2005 FINANCIAL HIGHLIGHTS

(Comparisons are given to the third-quarter 2004 results, unless otherwise indicated.)

Nokia Group

Nokia’s third-quarter 2005 group net sales increased by 18% to EUR 8.4 billion, compared with EUR 7.1 billion in the third quarter 2004. At constant currency, group net sales would have increased by 23%. All four of Nokia’s business groups contributed to this year-on-year sales growth.

Nokia’s third-quarter 2005 operating profit grew 19% year on year to EUR 1.1 billion (including the positive impact of special items of EUR 87 million), compared with EUR 969 million in the third quarter 2004 (including a net negative impact of special items of EUR 18 million). Nokia’s third-quarter 2005 operating margin was 13.7% (13.6%).

Operating cash flow for the third quarter 2005 was EUR 1.2 billion, compared with EUR 510 million for the second quarter 2005, and total combined cash and other liquid assets were EUR 11.0 billion, compared with EUR 11.2 billion at June 30, 2005. As of September 30, 2005, our net debt-equity ratio (gearing) was -82%, compared with -80% at June 30, 2005.

Mobile devices

In the third quarter 2005, the total mobile device volume achieved by our Mobile Phones, Multimedia and Enterprise Solutions business groups reached 66.6 million units, representing 29.5% year-on-year growth and 9.5% sequential growth. Overall industry volume for the same period reached an estimated 199 million units, representing 25% year-on-year growth and 9% sequential growth.

In smartphones, according to Nokia estimates, the total industry volume reached about 14 million units for the third quarter 2005, compared with an estimate of 5.2 million units in the third quarter 2004. Nokia’s own smartphone volume grew to 7.1 million units, compared with 2.9 million units in the third quarter 2004.

The following chart sets out Nokia’s mobile device volume for the periods indicated as well as the year-on-year and sequential growth rates by geographic area.

NOKIA MOBILE DEVICE VOLUME BY GEOGRAPHIC AREA

Strong volume growth in China continued to be driven by sales across the range of Nokia’s broad product portfolio through our extensive distribution system.

In Asia Pacific, strong sequential volume growth reflected our ability to capitalize on strong market growth, particularly in the fastest growing market, India, where we kept our market share and industry-leading position.

In Europe/Middle East/Africa, sequential growth largely reflected continuing strong overall market growth in the Middle East, Africa and Russia.

In Latin America, Nokia’s third-quarter volumes declined sequentially, reflecting lower volumes in the market overall and a lower Nokia share. North America remained a challenging environment for Nokia.

Based on our preliminary market estimate, Nokia’s market share for the third quarter 2005 grew to 33%, compared with 32% in the third quarter 2004. Sequential market share was stable compared with the second quarter 2005, reflecting strong gains in China and Asia Pacific, offset by a significant share decrease in Latin America and to a lesser extent in North America. We maintained our market share in Europe/Middle East/Africa.

3

Nokia average selling prices in the third quarter 2005 declined to EUR 102, compared with EUR 108 in the third quarter 2004 and EUR 105 in the second quarter of this year. Average selling prices continued to trend down primarily reflecting strong volume growth in emerging markets. However, Nokia third-quarter average selling prices benefited from the company’s success in China, Asia-Pacific and Europe/Middle East/Africa.

Mobile Phones: Third-quarter 2005 net sales grew 15% to EUR 5.2 billion, compared with EUR 4.5 billion in the third quarter 2004, driven by good demand, our product competitiveness and relatively firm prices. Sales growth was strongest in China, followed by Asia Pacific and Europe/Middle East/Africa. Sales declined year on year in North America and to a lesser extent in Latin America.

Mobile Phones operating profit grew 4% to EUR 880 million, compared with EUR 848 million in the third quarter 2004, with an operating margin of 16.9% (18.8%). Profit growth in the third quarter 2005 was supported by a strong product portfolio and effective cost management.

Multimedia: Third-quarter 2005 net sales increased 55% to EUR 1.4 billion, compared with EUR 931 million in the third quarter 2004. Sales continued to be predominantly in Europe/Middle East/Africa, where growth was strongest, followed by Asia Pacific and then China. Sales in the Americas continued to be disappointing.

Multimedia third-quarter operating profit grew by 163% to EUR 245 million, compared with EUR 93 million in the third quarter 2004, with an operating margin of 16.9% (10.0%). Operating profit included a EUR 19 million gain related to the divestiture of Nokia’s Tetra business. Sales and profitability were driven by a strong sales performance in the high-end imaging smartphone business and effective cost management.

Enterprise Solutions: Third-quarter 2005 net sales grew by 16% to EUR 203 million, compared with EUR 175 million in the third quarter 2004. Sales were supported by the wider availability of mobile applications for the Nokia 9300 enterprise smartphone, with availability improving throughout the quarter.

Networks

Third-quarter 2005 net sales increased by 2% to EUR 1.6 billion, compared with EUR 1.5 billion in the third quarter 2004. Strong sales in Asia Pacific and Latin America were substantially offset by a sales decline in China, while sales in North America and Europe/Middle East/Africa were virtually unchanged.

Networks third-quarter operating profit declined by 20% to EUR 157 million, compared with EUR 197 million in the third quarter 2004, with an operating margin of 10.1% (12.9%). This included a EUR 42 million gain related to the divestiture of Nokia’s Tetra business and a EUR 18 million gain related to the partial sale of a minority investment.

Networks operating profit was negatively affected by a number of factors, including investments in our capability and presence in the growing network services market, and our ongoing push into new growth markets.
