Instrumentation supplier Renishaw increased revenues by 85% in the first quarter and pre-tax profit jumped from £2m to £15.1m. Revenues rose from £32.5m to £60.1m in the three months to September 2010, although this was a weak period for the business. China has been the main engine of growth and the Far East now accounts for 42% of revenues, up from 35% last year. Exchange rates flattered the profit figure by around £900,000 but it is still an impressive improvement. The comparatives are weak but the latest figure is still better than the £9.8m profit in the first quarter two years ago. Renishaw had net cash of £30.8m at the end of September 2010Enterprise software firm Autonomy is continuing its decline even though it signed up a UK regulatory authority responsible for financial industry oversight as a client yesterday. It is a multi-million pound deal. The share price has fallen by nearly 105 over the past week and by nearly one-quarter over one month - due to the recent profit warning.
