SONERA'S PERFORMANCE CONTINUES TO IMPROVE DURING THE FOURTH QUARTER

EUR million	Oct.- 2002	Dec. 2001		Change %
Revenues	606	556		9
Underlying EBITDA	214	155		38
Underlying EBITDA margin, %	35.3	27.9

Reported operating profit	33	(38	)	n/m

Free cash flow	40	(2	)	n/m

Consolidated revenues in the fourth quarter of 2002 grew 9% to EUR 606 million (EUR 556 million in the fourth quarter of 2001), mainly due to the acquisition and consolidation of Fintur. Comparable revenues increased by 5%, taking into account all businesses divested and the pro forma revenues of Fintur.

Underlying EBITDA (excluding all non-recurring items) hit record highs for the fourth quarter in a row, rising to EUR 214 million (155) in the fourth quarter, representing 35.3% of revenues (27.9%). The improvement was mainly due to the narrowing of EBITDA losses from Service Businesses, and the consolidation of Fintur.

Underlying operating profit also improved to EUR 121 million (75), showing a growth of 61 percent, while the reported operating profit improved to EUR 33 million (loss of EUR 38 million). Reported operating profit for the fourth quarter of 2002 also includes a non-cash write-down of EUR 72 million on Xfera, a Spanish UMTS joint venture where Sonera holds 14.25%.

Sonera's equity loss in associated companies in the fourth quarter narrowed to a loss of EUR 3 million (loss of EUR 67 million), primarily due to the improved results of Turkcell, and the discontinued equity accounting for Group 3G in Germany, the carrying value of which Sonera wrote down to zero in the second quarter of 2002. Equity loss in the fourth quarter also includes a EUR 32 million goodwill write-down of MetroOne.

The underlying profit before income taxes and minority interest improved to EUR 132 million (11). The reported profit before income taxes and minority interest for the fourth quarter rose to EUR 4 million (loss of EUR 8 million in 2001). The reported net income was EUR 119 million (56) in the

fourth quarter, including a deferred tax benefit of EUR 124 million (65) recorded for the fourth quarter.

The underlying earnings per share were EUR 0.21 (EUR 0.07) while the reported earnings per share were EUR 0.11 (0.06).

Cash provided by operating activities in the fourth quarter grew to EUR 145 million (91). Cash from operating activities was improved by higher underlying EBITDA and lower interest expenses. Though capital expenditures also increased to EUR 105 million (93), free cash flow (cash from operating activities less capital expenditure on fixed assets) for the fourth quarter improved to EUR 40 million (EUR 2 million negative).

REPORT OF THE BOARD OF DIRECTORS FOR 2002

After the slow growth of the world economy in 2001, growth accelerated somewhat in the early part of 2002, but has subsequently been more sluggish than expected. In the first half of 2002, growth also accelerated modestly in Finland from the very low level of 2001, led by exports and private consumption.

Toward the end of 2002, Finland's mobile phone penetration rate rose to approximately 85%. Sonera's market share of GSM subscriptions at the end of 2002 was slightly below 60%. Mobile Communications Finland was Sonera's main business area, accounting for 55% of consolidated revenues.

In March 2002, Sonera and Telia AB of Sweden announced a plan to merge. The merger was completed in early December. The merged entity, renamed TeliaSonera, is the largest telecommunications operator in the Nordic region.

During 2002, Sonera also refocused its business organization to an integrated customer-driven approach, successfully continued its cash flow improvement and debt reduction programs, and acquired control in Fintur GSM operations as part of Sonera's growth strategy.

Based on changes in circumstances and expectations, the quarterly impairment analyses performed by Sonera on its international UMTS investments resulted in non-cash write-downs in 2002 totaling EUR 4,352 million before taxes, or EUR 3,117 million net of deferred tax benefit.

UNDERLYING EBITDA IMPROVES BY 42% AND FREE CASH FLOW TURNS POSITIVE

Consolidated revenues in 2002 grew by 2% from the previous year and totaled EUR 2,241 million (EUR 2,187 million in 2001), due to the acquisition of Fintur. Comparable revenues grew by 6%, taking into account the businesses divested and the pro forma revenues of Fintur.

Underlying EBITDA (excluding all non-recurring items) improved by 42% and was EUR 799 million (562), representing 35.7% of revenues (25.7%). The improvement was mainly due to the narrowing of EBITDA losses from Service Businesses and the acquisition of Fintur.

Underlying operating profit doubled to EUR 460 million (230) while the reported operating profit remained at EUR 234 million (951). The reported operating profit in 2002 also includes capital gains of EUR 392 million mainly relating to the sales of Pannon, Sonera Info Communications, Primatel and Libancell; non-cash write-downs of EUR 597 million mainly relating to Ipse 2000, Xfera, Juniper Financial Corporation and 724 Solutions Inc.; expenses of EUR 13 million relating to the merger with Telia; and other non-recurring expenses of EUR 48 million mainly relating to the restructuring of operations and write-downs. In 2001, the reported operating profit included non-recurring gains totaling EUR 890 million, mainly relating to the sales of TietoEnator, VoiceStream and Powertel; and non-recurring losses of EUR 169 million, mainly relating to write-downs and restructuring of operations.

Sonera's equity loss in associated companies in 2002 increased to EUR 3,977 million (loss of EUR 202 million), primarily due to a non-cash write-down recorded for Group 3G in the second quarter of 2002.

The underlying profit before income taxes and minority interest improved to EUR 325 million (loss of EUR 4 million), mainly due to significant improvement in the underlying EBITDA. As a consequence of the non-cash write-downs of international UMTS investments, the reported loss before income taxes and minority interest in 2002 was EUR 3,828 million (profit of EUR 445 million). The reported net loss was EUR 2,497 million (profit of EUR 409 million).

The underlying earnings per share improved to EUR 0.36 (0.07) while the reported loss per share was EUR 2.24 (earnings per share of EUR 0.44).

Cash provided by operating activities in 2002 grew more than three-fold to EUR 654 million (197). Free cash flow (cash from operating activities less capital expenditure on fixed assets), improved to EUR 379 million from the negative free cash flow of EUR 162 million in 2001.

Net debt continued to decrease significantly during 2002, and totaled EUR 2,101 million on December 31, 2002 (EUR 3,268 on December 31, 2001).

During the year, Sonera's average payroll was 8,169 (10,482), showing a decrease of 22%, primarily due to the divestment of business operations. At the end of 2002, the number of employees was 7,639, showing a decrease of 24% from the year-end 2001. The acquisition of Fintur added some 850 employees in the consolidated number.

(1): Excluding service providers.

Revenues from Mobile Communications Finland were up 2% on the previous year, reaching EUR 1,237 million (1,213). Revenue growth was supported by increased usage of mobile services and the revised sharing of mobile-originated international call revenues between Mobile Communications Finland and Sonera Telecom. However, revenue growth was slowed due to new interconnection agreements that began September 2001, lower SMS prices, high overall penetration, as well as the strategic goal to seek profitable growth. Revenues from non-voice services remained at EUR 147 million (147).

The profitability of the business area continued to be very strong. Underlying EBITDA for 2002 was EUR 618 million (604), corresponding to 50.0% of revenues (49.8%). Operating profit was EUR 493 million (477). Profitability improved due to increased revenues, continued cost control, and process development efforts. Capital expenditures for the business area were EUR 98 million (102). The simplified free cash flow measure as applied to Sonera's business areas, underlying EBITDA less capital expenditure, improved by 4% to EUR 520 million (502).

During 2002, the average monthly use of a Sonera mobile subscription rose by 4% to 151 minutes (145) and average monthly revenues per user (ARPU) were EUR 40.0 (40.5). The average number of text messages sent from a Sonera GSM subscription per month was 27.2 (26.4), representing a rise of 3%.

The number of Sonera's GSM subscriptions grew by a net 68,244 from the end of 2001, and was 2,489,777 at the end of 2002 (2,421,533). Sonera's primary goal is to focus on long-term profitable growth rather than market share. GSM customer churn grew to 12.6% (10.1%) due to increased price competition. Including service provider subscriptions, the total number of all GSM subscriptions in Sonera's network was 2,524,915 at the end of the year (2,510,028).

(1): Includes Fintur from the beginning of September 2002.
(2): Pro forma presents the Fintur transaction as if it had already taken place on January 1, 2001.

In August 2002, Sonera completed the purchase of an additional 23.24% interest in Fintur Holdings B.V. from the Çukurova Group, raising its total holding in Fintur to 58.55%. As part of the transaction, Fintur's loss-making technology and media businesses were sold to the Çukurova Group. Sonera paid a purchase price of approximately EUR 117 million and assumed interest-bearing net debt of Fintur of approximately EUR 125 million.

Fintur operates through its majority-owned subsidiaries in the emerging GSM markets of Azerbaijan, Georgia, Kazakhstan and Moldova. As of December 31, 2002, Fintur had approximately 1.6 million subscribers, a growth of 43% as compared to December 31, 2001.

Sonera consolidated Fintur as of September 2002, allowing only four months of Fintur's results of operations to be included in Sonera's income statement for 2002. In the fourth quarter, the combined revenues of Fintur companies totaled USD 65 million (USD 48 million in the fourth quarter of 2001), underlying EBITDA 36 million (21) and operating profit USD 24 million (11). On a pro forma basis for the full year 2002, Fintur recorded revenues of USD 240 million (USD 175 million in 2001), underlying EBITDA of USD 123 million (64) and operating profit of USD 75 million (26).

Sonera's equity loss in mobile associated companies, before goodwill amortization and write-downs, was EUR 76 million (loss of EUR 180 million) in 2002, mainly due to improved results of Turkcell and Fintur as compared to 2001.

Equity income recorded from Turkcell was EUR 7 million (loss of EUR 61 million) for Sonera's 2002 income statement. Turkcell is consistently included in Sonera's equity income with a three-month lag. Turkcell's net income in 2002 turned positive as a result of the subscriber growth effects on revenues and EBITDA. The foreign exchange losses and financial expenses of Turkcell also decreased and contributed to the improved net income. On December 31, 2002, Turkcell had 15.7 million customers, consisting of 4.7 million post-paid and 11.0 million pre-paid subscribers.

Equity income recorded from other GSM associated companies decreased to EUR 43 million (56), primarily due to the sale of Pannon GSM during the first quarter of 2002.

In Russia, the restructuring of MegaFon was completed in 2002, and Sonera holds 26% in the new company. The customer base of MegaFon grew by approximately 2.1 million during 2002 and totaled approximately 3.0 million at the end of the year.

In July, Sonera, assisted by a third party advisor, performed impairment analyses based on its international UMTS investments due to changed circumstances and assumptions, which led to a EUR 3,844 million non-cash write-down of Sonera's investment in Group 3G for the second quarter of 2002. The write-down reduced the carrying value of Sonera's investment to zero. Sonera also wrote down its investment in Ipse, totaling EUR 294 million. Additionally, Sonera charged its Ipse-related capital commitments of EUR 143 million to expense.

As a result of its EUR 4,280 million write-down of its UMTS investments in Germany and Italy, Sonera recorded a deferred tax benefit of EUR 1,235 million in the second quarter of 2002. Although Sonera currently estimates that the deferred tax asset can be realized in six to eight years under different scenarios, there can be no assurance of sufficient taxable income within this period. Tax loss carry-forwards in Finland expire after ten years. Sonera has also received advance rulings that these write-downs created a tax benefit in Finland, and that the tax benefit can also be utilized after the TeliaSonera merger.

As part of its quarterly review of carrying values, Sonera also performed an impairment analysis on Xfera of Spain as of December 31, 2002. Based on the continued delay for the launch of 3G services in the market, and further negative changes in the market expectations during the fourth quarter of 2002, the analysis led to a non-cash write-down of Sonera's investment in Xfera totaling EUR 72 million. The write-down of Xfera did not result in a deferred tax benefit. In January 2003, the Spanish government proposed a bill to allow frequency trading in Spain. Additionally, there are indications that the Spanish government may consider lowering significantly the amount of performance guarantees issued by the license holders in Spain.

SERVICE BUSINESSES—BEATING THE EBITDA LOSS-REDUCTION TARGETS

Revenues from Service Businesses decreased by 12% to EUR 284 million (321) in 2002, primarily due to the divestment of Sonera Info Communications at the end of March 2002. Underlying EBITDA loss for the business area decreased significantly to EUR 41 million (loss of EUR 244 million), clearly beating the target of EUR 50 million. Due to a sales gain recorded in the first quarter, reported operating loss for the business area remained at EUR 12 million (loss of EUR 384 million). Underlying operating loss decreased to EUR 81 million (loss of EUR 291 million) in 2002. Capital expenditures totaled EUR 18 million (53). The simplified free cash flow measure as applied to Sonera's business areas, underlying EBITDA loss plus capital expenditure, narrowed to EUR 59 million (297) of cash spent.

Revenues from Sonera Telecom were EUR 991 million (1,024) in 2002, decreasing by 3% mainly due to the sale of Primatel and the Gateway leasing business at the end of May 2002. On a comparable basis, however, revenues increased by 5% when taking into account disposals of businesses.

Underlying EBITDA for the business area decreased to EUR 176 million (230) in 2002, primarily due to the revised revenue sharing of mobile international call revenues between Sonera Telecom and Mobile Communications Finland from the beginning of 2002 and the sale of Primatel and Gateway operations. The reported operating profit was EUR 90 million (108) and the underlying operating profit was EUR 59 million (107). Capital expenditure for the business area was reduced to EUR 110 million (186) in 2002. The simplified free cash flow measure as applied to Sonera's business areas, underlying EBITDA less capital expenditure, therefore improved to EUR 66 million (44) in 2002.

At the end of 2002, the total number of equivalent fixed network access lines in Finland was 721,194 (753,140), showing a decrease of 4%. The number of ADSL and other broadband consumer connections continued to show strong growth and totaled 59,628 at the end of the year (11,603). The largest share of Sonera's ADSL base is in the large cities, and more than half of the base is outside of Sonera's traditional service areas.

Sonera's equity income in its Baltic and Finnish fixed network associated companies decreased to EUR 26 million (35) primarily due to decreased revenues of Lattelekom and Lietuvos Telekomas because of tightening competition. The estimated number of subscriptions of the associated companies totaled approximately 2.3 million at the end of the year.

In January 2002, pursuant to an option in the shareholder agreement, International Finance Corporation (IFC) sold its 10% minority stake in Sonera's Danish holding company Tilts Communications A/S to Sonera for EUR 34 million (US$30 million). After the deal, Sonera owns 49% of the shares in Lattelekom SIA, the largest fixed line operator in Latvia. In January 2002, Sonera also increased its holding in Loimaan Seudun Puhelin Oy (LSP) by 5% to a total of 29.1%. LSP is a local fixed line operator in southwestern Finland.

LEGAL AND REGULATORY DEVELOPMENTS

In May, the parties to Lattelekom arbitration stated their claims. Tilts Communications A/S, Sonera's wholly-owned Danish subsidiary, claims approximately EUR 152 million from the Republic of Latvia as compensation for losses sustained as a consequence of the shortening by the Republic of Latvia of the twenty-year exclusivity period granted to Lattelekom in 1994, and failure by the Republic of Latvia to ensure that telecommunications tariffs were fixed at contractually agreed levels. The Republic of Latvia has quantified counterclaims of approximately EUR 1,040 million, principally arising from the alleged failure by Tilts to digitalize the fixed network in Latvia and certain other alleged breaches by Tilts of its obligations. Sonera considers that it has valid claims against the Republic of Latvia and will pursue these. Sonera also believes that the counterclaims by the Republic of Latvia are unfounded and will vigorously defend itself against these counterclaims. Sonera's current holding in Lattelekom is 49%.

In July, the Supreme Administrative Court accepted an appeal that Sonera filed in January 2002 against the Competition Council's decision to prohibit Sonera's acquisition of 16.7% in Loimaan Seudun Puhelin Oy (LSP). After the Supreme Administrative Court's decision, Sonera will start taking the measures required by the initial approval by the Finnish Competition Authority in August 2001. Sonera's current holding in LSP is 29.1%.

In July, the Finnish Communications Regulatory Authority (FICORA) issued its decision on a complaint filed by Telepohja Oy in January 2000 concerning the pricing of Sonera's leased line operations especially in rural areas. In its decision, the FICORA states that Sonera's pricing is cost-oriented as required by the legislation, and that Sonera has operated in compliance with the Communications Market Act (formerly, Telecommunications Market Act). Telepohja also filed a similar complaint with the Finnish Competition Authority (FCA) in January 2000; the complaint is still pending.

In August, a settlement was reached in respect of the dispute between Sonera and Harri Vatanen, former CEO of Sonera SmartTrust Ltd, about the Sonera SmartTrust technology and the termination of Mr. Vatanen's employment. The parties agreed to terminate all pending legal actions in full.

In September, the Administrative Court of Helsinki issued a decision on the appeal filed by Sonera against the decision issued in April 2001 by the Finnish Communications Regulatory Authority (FICORA, formerly the Telecommunications Administration Centre). The Administrative Court of Helsinki stated that the FICORA's opinion of Sonera's interconnection pricing in domestic mobile communications not being reasonable in relation to the actual costs would not be considered erroneous. Sonera appealed the decision to the Supreme Administrative Court in October. The decision issued by the FICORA in April 2001 is not enforceable until the Supreme Administrative Court has issued its decision. Sonera believes that the correct price level for interconnection traffic should be based on commercially negotiated solutions. In the spring and summer of 2001, Sonera concluded new mobile interconnection agreements with all mobile network operators in Finland. The interconnection fees of Sonera's mobile communications are lower than those of other Finnish operators and are also low in international comparison. A similar case is also pending at the Finnish Competition Authority.

In October, Sonera requested the police to investigate the allegations published in the media according to which the Company had violated the secrecy of communications in the years 2000 and 2001. After this, the police launched a pre-trial investigation.

In November, Sonera was served a writ by Broadband Mobile ASA bankruptcy estate, claiming a total of NOK 332 million (approximately EUR 45 million) from the shareholders of Broadband Mobile (Sonera 50%). On December 18, 2002, Sonera filed a response to the writ with a district court in Norway. The hearing of the case is not expected to take place until at the end of 2003.

CLEARLY IMPROVED FREE CASH FLOW

Cash provided by operating activities in 2002 more than tripled to EUR 654 million (197). Cash from operating activities was improved primarily by higher underlying EBITDA and lower interest expenses. Cash paid for net interest expenses reduced significantly to EUR 87 million (278) as a result of lower net debt. Dividends received from associated companies totaled EUR 44 million (47) in 2002.

Capital expenditures on fixed assets decreased by 23% to EUR 275 million (359) in 2002, representing 12.2% of revenues (16.4%). Free cash flow (cash from operating activities less capital expenditure on fixed assets) improved significantly to EUR 379 million in 2002 from the negative free cash flow of EUR 162 million in 2001.

Equity investments and shareholder loans granted also remained lower than last year at EUR 170 million (572). The largest individual equity investment during the year was the payment of EUR 120 million for the Fintur acquisition, less cash acquired of EUR 17 million.

During the year, Sonera received proceeds of EUR 1,024 million (2,193) from asset sales, mainly due to the sale of Pannon GSM, Sonera Info Communications, the remaining Deutsche Telekom shares, Primatel, Gateway leasing business, and Libancell.

PROPOSAL OF THE BOARD OF DIRECTORS FOR PROFIT DISTRIBUTION

According to the financial statements as of December 31, 2002, the Group's distributable funds totaled EUR 576 million, and the corresponding amount for the Parent Company was EUR 356 million.

After the exchange offer by TeliaSonera was completed in December 2002, Sonera became a subsidiary of TeliaSonera. The Board of Directors proposes to Sonera's annual general meeting that no dividend be paid for the 2002 fiscal year.

TeliaSonera's profit distribution will be approved in the Annual General Meeting of TeliaSonera AB, based on the proposal by the TeliaSonera Board of Directors.

Financial information

The financial information given in this report is based on Sonera's consolidated financial statements that are prepared in accordance with Finnish accounting practice.

This report includes information on "underlying EBITDA" and on other similar "underlying" measures of Sonera's results of operations. Underlying EBITDA equals operating profit before depreciation and amortization, before gains and losses from sale of shares and fixed assets, before write-downs, and before restructuring expenses. Sonera's management believes that, except for depreciation and amortization, these items excluded from the definition of underlying EBITDA do not reflect the underlying fundamentals of the operating results from Sonera's business segments. Sonera's management also believes that underlying EBITDA is a standard measure commonly reported and widely used by analysts, investors and others in the telecommunications industry. Accordingly, this information has been disclosed to permit a more complete comparative analysis of the segmental operating performance relative to other companies in the industry. Underlying EBITDA, however, should not be considered as an alternative to operating profit as an indicator of operating performance. Similarly, underlying EBITDA should not be considered as an alternative to cash flows from operating activities as a measure of liquidity. Underlying EBITDA is not a measure of financial performance under Finnish GAAP or U.S. GAAP and may not be comparable to other similarly titled measures for other companies. Underlying EBITDA is not meant to be predictive of potential future results.
