Pre-close announcement

Pre-close meetings 28 June 2013 Ahead of Serco Group plc entering its close period for the half-year ending 30June 2013, and following the recent Interim Management Statement released on 15May 2013, we will be holding our customary pre-close meetings with analystsover the coming days. No new material information will be disclosed. The Groupis on track to meet expectations for 2013: for the full year, we expect amodest improvement in the rate of organic revenue growth and the Adjustedoperating margin to be broadly maintained around the level achieved in 2012. Weremain confident in the ongoing resilience, overall outlook and future growthprospects for the Group. For the first half of 2013, we expect to report strong organic revenue growthahead of our expectations. This is driven in part by last year's record levelof contract awards, many of which only started part way through last year,together with additional revenue from certain volume-related and project-basedwork. The effect of last year's acquisitions and disposals has a broadlyneutral impact on total revenue growth. Supporting the strong pipeline and market opportunities in the Global Servicesdivision, the level of investment in contract bidding and new marketdevelopment activity has increased. Including the effect of this, a smallreduction in the Adjusted operating margin for the Group as a whole isanticipated for the first half of 2013. The comparable period's Adjustedoperating margin, before the reorganisation costs incurred in 2012, was 5.9%. The net effect of stronger revenue growth and the small reduction in Adjustedoperating margin is expected to result in an Adjusted operating profit for thehalf-year that is in line with our original expectations. Driven principally by the incremental working capital investment that issupporting BPO growth as previously disclosed, the phasing of free cashgeneration over the course of 2013 is anticipated to be broadly similar to theprior financial year. Serco will release its half-year results on Thursday 29August 2013. Aspreviously described, our reporting will now reflect the changes to accountingstandards IAS19 and IFRS11. Neither of these have a material impact on theGroup's reported earnings. A restatement of the 2012 financial year (aspreviously provided) and the first half of 2012 is published today onwww.serco.com.
