Shares in BTG have fallen following the release of its interim management statement for the period between 1 October 2010 and 27 January 2011. BTG says that its recurring revenues will grow by £5m following the Biocompatibles acquisition. This will take them to £98m-£102m in the year to March 2011. Additional one-off revenues take the full year revenue range to £108m-£114m. Peel Hunt still expects a loss of around £5m. Cash in the bank is expected to be between £68m and £73m by the end of March 2011. Instrumentation and sensors supplier Renishaw continues to rise following yesterday's positive interim statement. Operating profit jumped from £6.92m to £35m in the six months to December 2010. This improvement was down to a strong turnaround in the metrology division. The healthcare division increased its loss. FinnCap has upgraded its profit forecast for the year to June 2011 from £55.9m to £73.6m.
