• Serco Group are a services support group which means they provide outsourcing to the public and private sector. Where is there 'potential expansion and scope' which they say is boosting revenue growth? Currently, they provide 40 pct of their projects to the Government, 25 pct to defence, 20 pct to transport and 15 to pct science. Out of those only science appears to be relevant as the others are subject to the government's fiscal deficit cutbacks – whereas science is the only sector to receive money the private sector. In UK, most support services revolve around Government spending and unless Serco Group's contracts become more and more efficient, then how will they make more money?

• Operating Margins are said to be targeted for 6.3 pct by 2012, which Serco say they are on target to meet. Looking at its margins in each sector, transport and science are the highest. They have recently been given a contract for the Dubai metro, and have experience running the DLR in East London, therefore have a specialist market in those wanting to run driverless-train systems.

• Broker views: 2.11 (7 Buy, 4 Outperform, 6 Hold, 1 Sell). Panmure Gordon analysts are the only company to have this services firm on 'sell' with the reasoning that 19x profit/earnings is too high. Mitte has 12 x P/E, whereas Carillion has 8 x P/E albeit with 30 pct construction sector exposure. Carillion is rated a 'buy' at Panmure Gordon by analyst Andy Brown. "Although (Serco) has said it is progressing well, I would put it down to investor preference, or they think there's no need to buy more at this stage," added Henry Carver, analyst at KBC Peel Hunt today who also has a hold rating on support services rival 'Mouchel'.

• With half year results due on 25th August, guidance for 2010-12 is to raise revenues to around £5bn with adjusted operating profit margin 6.3%. This requires a raise of revenue to £2.25bn for this half year for which they say they are on track.
