YIT CORPORATION STOCK EXCHANGE RELEASE JULY 21, 2003 11:00 1(1)

YIT’S
ACQUISITION OF ABB’S BUILDING SYSTEMS BUSINESS IN
FINLAND APPROVED BY THE
FINNISH COMPETITION AUTHORITY

On July 4, 2003 YIT Corporation signed an
agreement whereby it
purchased from ABB the company’s Building Systems
operations, which
offer technical building systems, property and industrial
services in
Finland, Sweden, Norway, Denmark, the Baltic states and
Russia.
The approval of the competition authorities was required before
the
deal will enter into force. On July 18, 2003, the Finnish
Competition
Authority announced that it has approved the acquisition of
the
Building Systems operations in Finland. "The acquisition
neither
establishes nor strengthens a dominant market position,
which
significantly would restrict the competition on the Finnish market or
a
substantial part thereof", the Competition Authority states in
its
decision.
