Computer Management Group Plc is at an advanced stage of talks to take over an unnamed German company that would double its turnover in that country, the UK computer services company said yesterday. No further details of the planned transaction were given. The company, which had planned to float this half, but postponed it because it didn’t like the look of the market weather forecast, produced updated 1994 figures showing net profit up 50% at ú8.1m – pre-tax was up 24.3% at ú13.8m, and turnover was up 14% at ú146.3m. It took a ú453,000 hit for the cost of the aborted flotation. On Germany, Computer Management said its existing loss-making unit there was on course to become profitable in 1995.
