Eidos plc Trading Update

    LONDON--(BUSINESS WIRE)--May 20, 2004--Eidos plc ("Eidos"),
(LSE:EID.L, NASDAQ:EIDSY), one of the world's leading publishers and
developers of entertainment software, today provides an update on
trading during the second half of the financial year to 30 June 2004.
    The initial shipments of Hitman: Contracts, released in the last
week of April, have been broadly in line with management expectations.
The title has reviewed well and has shipped approximately 1.5 million
units to date. The title has also achieved number one rating status in
the UK, France, Germany and the US during the first two weeks of
launch.
    However, the recent and unexpected softness of the games market,
particularly in the US, is having a negative effect on the unit sales
of Hitman: Contracts and will, therefore, adversely impact upon the
Company's financial performance for the full year. Based on overall
sell-through rates to date, management has identified a potential
shortfall exposure of c.700,000 units of previously anticipated
re-orders that are now unlikely to materialise. Whilst the operating
profit contribution from the re-orders would have been expected to be
in the region of GBP 9 million, the actual impact on the year-end
outcome, while very significant, will depend upon a number of other
factors, including the on-going sales of other titles.
    The Company has two remaining titles scheduled for release prior
to the end of the financial year, Thief: Deadly Shadows and
ShellShock: Nam '67. Thief is in manufacture for shipment on 25 May in
the US and 11 June in Europe. ShellShock is in the approval process
and is due to ship in the last week of the financial year as
originally forecast.
    Eidos intends to announce its full year results for the current
financial year in early September. The Company will keep the market
informed in a timely manner should any material changes occur in the
intervening period.
    In the light of continuing media speculation concerning a possible
approach to the Company, the Board can confirm that it has received no
such approach and is not in discussions with any party concerning a
possible offer.
    Eidos is the largest video games publisher and developer of
entertainment software in the UK. It has publishing operations across
Europe (France, Germany, Spain and the UK) and in the US, Japan and
Australia. It also has significant development studio expertise, both
internal and external, in Europe and the US.

    Eidos plc is a public limited company registered in England
(number 2501949). Its Ordinary shares are listed on the London Stock
Exchange (ticker: EID.L) and, in the form of American Depositary
Shares, on the NASDAQ National Market (symbol: EIDSY). Further
