Fidessa Group plc Interim Management Statement

Fidessa group plc (LSE: FDSA), a leading global provider of multi-asset trading
systems, market data and global connectivity solutions, is releasing its interim
management statement for the period from 1 January 2008 to date.

The year has started well with strong revenue growth and stable margins. Good
progress has been made across all regions and product lines and the indications
are that the structural changes in the market, which occurred in 2007, are
resulting in increased fragmentation of liquidity which is driving demand for
our product set. The strong demand means that we expect that results for the
year are likely to be around the upper end of market expectations.

At this stage, we are seeing no measurable change in buying cycles as a result
of the credit problems currently affecting the global financial markets. We have
seen some acceleration of M&A and restructuring activity within our customer
base, such as JP Morgan's proposed acquisition of Bear Stearns, but the breadth
and depth of our client relationships lead us to believe that, at present, this
will have minimal impact on our revenues in the foreseeable future. In addition,
the underlying strength of our business, with high levels of recurring revenue,
strong cash generation and no debt, leaves us well positioned to meet any
challenge should the situation in the financial markets worsen over the coming
months.

Commenting on Fidessa's performance over the period, Chris Aspinwall said: "We
are pleased to be able to report continued strong demand for our products and
services across the regions and believe that this is likely to be reflected in
results around the upper end of market expectations for 2008 as a whole"
