Beginning this quarter Sony Ericsson is expanding its financial disclosure. More
information can be found at the end of this report. This decision was made as a
result of the company's continuing growth and in consultation with the parent
companies.

Units shipped in the quarter reached 21.8 million, a 63% increase compared to
the same period last year, generating significant year-on-year market share
gains and continuing the momentum of 2006. Sales for the quarter were Euro 2,925
million, representing a year-on-year increase of 47%. Income before taxes for
the quarter was Euro 362 million representing a year-on-year increase of 139%.
Net income for the quarter was Euro 254 million. ASP decreased to Euro 134 as we
continue to expand our product portfolio successfully with mid-tier and with
more competitively priced phones.

"Sony Ericsson has made a very positive start to the year selling 63% more
phones in the first quarter than a year ago. The strong sales and solid
financial performance demonstrate a continuation of the momentum we established
last year," said Miles Flint, President of Sony Ericsson. "We have announced a
number of exciting new products during the quarter many of which are already
shipping and have been well received by consumers. The company continues to
develop hit model products with a clear consumer proposition that appeals to
operators, and then rapidly ramp-up volume to meet market demand," he added.

Sony Ericsson continued to build on the success of 2006 with strong growth in
Asia Pacific, Latin America and Europe. The company captured market share in
these markets through low and mid-tier products such as the W300 and W200
Walkman(R) phones and the K310 camera phone without undermining profitability.
Margins improved year-on-year despite the increased proportion of mid and low
tier products in the line-up illustrating management's focus on controlling cost
and maintaining margins while expanding Sony Ericsson's appeal to a wider
market.

Sony Ericsson also announced a number of attractive new products during the
quarter, including two new Cyber-shot(TM) phones, five additional Walkman(R)
models across a variety of price points to further strengthen its unique music
offering, and its first HSDPA handset aimed primarily at the North American
market.

In February in Japan Sony Ericsson started shipping the SO703i, a mobile phone
with selectable Style-Up panels that include a scented sheet to match the
panel's design, for NTT DoCoMo, and the W51S, a new clam-shell phone with
illuminated icons, for au (KDDI). Both phones were well received by consumers.

During the quarter Sony Ericsson made a number of strategic announcements:

Following the rapid growth in sales in the Asia Pacific region, the company
announced plans to start manufacturing phones in India through its global
manufacturing partners, Flextronics and Foxconn.

In February Sony Ericsson announced it had completed the acquisition of the
Swedish software company UIQ Technology AB, and established a separate holding
company, UIQ Holdings, to manage the business.

In March Sony Ericsson signed licensing and development agreements concerning
entry-level GSM, GPRS and EDGE mobile phones with Sagem Communication (SAFRAN
Group). Through this co-operation, Sony Ericsson will be able to strengthen its
position in the entry level area of the market.

Sony Ericsson forecasts that the 2007 global handset market will be above 1.1
billion units. The company believes that in Q1 2007 it grew market share around
2 percentage points compared with the same period last year to over 8%.

Sony Ericsson will make a total payment of Euro 848 million to its parent
companies in 2007 in the form of dividends, or both a dividend and a capital
redemption.
