Pre-close Statement

28 June 2011

Ahead of meetings with analysts prior to its half year end on 30 June 2011,
Serco Group plc (Serco) reconfirms the guidance given in its Interim Management
Statement on 9 May 2011.

For 2011, we expect good organic revenue growth and progress towards our 2012
margin guidance. By the end of 2012 we expect increases in revenue to
approximately £5bn and in Adjusted operating profit margin to approximately
6.3%; these increases exclude material acquisitions, disposals and currency
effects.

We remain encouraged by the developments in our markets across the world.
However, as previously noted, the market in the UK remains challenging, with
short-term headwinds resulting from government austerity measures, together
with some uncertainties regarding public service reform.

The acquisition of Intelenet, announced on 31 May 2011, is expected to complete
in the coming weeks.

Serco will release its 2011 half year results on 24 August 2011.
