TechMARK movers: Trafficmaster approach

Traffic information supplier Trafficmaster says that it is in discussions with a potential bidder. The share price has risen by one-fifth over the past week and this forced Trafficmaster to admit to the bid talks. The driving and vehicle services provider reported lower than expected revenues of £57.5m for 2009, but operating profit was better than expected at £6.7m. There was a £1m stock write-down in 2009. Traffic services fell into loss but the business services division reported sharply higher profits.LED products supplier Dialight is paying £3m in cash and shares for Denmark-based BTI Light Systems A/S. BTI supplies obstruction lighting and aids to navigation for the marine, wind and airport sectors. BTI reported a post-tax profit of £300,000 in the year to September 2009. The acquisition will enhance Dialight's position in the European offshore wind market.
