Pre-tax profit at telecoms billing software firm Intec Telecom surged after its business emerged from harsh global economic conditions relatively unscathed. The group, whose clients include AT&T, Cable & Wireless, said adjusted profit before tax surged to £11.1m in the first half of the year from £2.2m the same time a year earlier. For the six months ended March 31 revenue rose 40% to £80.3m. "The strong first half performance and improved pipeline visibility gives us a higher degree of confidence in delivering our financial targets in 2009 before currency benefits," Intec said in a company statement.High military spending in the UK and US helped defence group QinetiQ post a sharp rise in revenues and underlying pre-tax profits. In the year to March 31, pre-tax profits climbed to £130.2m from £109m on revenues that rose to £1.617bn from £1.366bn. The company's strong order book was sustained by continuing operations in Iraq and Afghanistan.FTSE TechMARK - RisersIntec Telecom (ITL) 52.25p +24.40%NXT (NTX) 10.75p +10.26%AEA Technology (AAT) 16.50p +4.76%Phoenix IT Group (PNX) 136.25p +1.68%Trafficmaster (TFC) 30.50p +1.67%Kofax (KFX) 122.50p +1.45%ProStrakan (PSK) 85.00p +1.19%Ricardo Group (RCDO) 202.00p +0.50%FTSE TechMARK - FallersPuricore (PURI) 11.50p -9.80%Torotrak (TRK) 35.00p -9.09%Alizyme (AZM) 5.60p -5.08%E2V Technologies (E2V) 88.00p -4.86%Alphameric (ALM) 24.50p -3.92%Imagination Technologies (IMG) 98.50p -3.43%Sinclair Pharma (SPH) 30.00p -2.44%Elan Corporation (ELA) € 5.17 -2.36%Oxford Biomedica (OXB) 10.75p -2.27%Anite Group (AIE) 32.50p -2.26%
