The consolidated financial summary for Sony Ericsson Mobile Communications AB
(Sony Ericsson) for the fourth quarter ended December 31, 2006 is as follows:

                                  Q4 2005   Q3 2006   Q4 2006     FY05      FY06
                                  -------   -------   -------    -----    ------
Number of units shipped (million)   16.1      19.8      26.0     51.2       74.8
Sales (EURO m.)                    2,310     2,913     3,782    7,268     10,959
Income before taxes (EURO m.)        206       433       502      512      1,298
Net income (EURO m.)                 144       298       447      350        997

Units shipped in the quarter reached 26.0 million, a 61% increase compared to
the same period last year, generating significant year-on-year market share
gains. Sales for the quarter were Euro 3,782 million, representing a
year-on-year increase of 64%. Income before taxes for the quarter was Euro 502
million representing a year-on-year increase of 144%. Net income for the quarter
was Euro 447 million.

Sony Ericsson increased market share during the quarter due to the continued
success of products such as the K800/K790 Cyber-shot(TM) phone and Walkman(R)
phone line-up. Average Selling Price (ASP) was slightly higher than expected due
to more favourable than expected market conditions and continuing strong demand
for Sony Ericsson's hit model handsets. Particularly strong growth in emerging
markets in Latin America and Asia Pacific, as well as in Europe, illustrates
Sony Ericsson's success at expanding the portfolio to increase market share in
new markets with attractive mid-tier products, and without undermining

"The fourth quarter saw Sony Ericsson finish a strong year with record volumes,
sales and net income due to the soaring popularity of our imaging and music
phones. Earlier investments in R&D and marketing have enabled us to expand the
portfolio and strengthen the brand to increase consumer and operator appeal. Our
target is to become one of the top three players in the industry, and the
momentum we established in 2006 makes this an achievable ambition," said Miles
Flint, President of Sony Ericsson.

Sony Ericsson estimates the 2006 global handset market as being around 980
million units, higher than previous forecasts of over 950 million units for the
year. On this basis the company believes it has outperformed the market during
the quarter, gaining around 1% of market share sequentially, to achieve a global
market share of approximately 9% during Q4. In Q4 2006 Sony Ericsson grew market
share slightly over 2% against the same period for the previous year.

During the fourth quarter Sony Ericsson announced it had reached agreement in
principle to acquire the Swedish software company UIQ Technology AB, a wholly
owned subsidiary and business of Symbian Ltd. Sony Ericsson expects the
transaction to be completed during the first quarter 2007.
