The Roxboro Group Plc, the Cambridge, UK-based components, sensors and instrumentation manufacturer, has reversed recent disappointments to produce some high quality figures in 1997, despite the strong pound and what the company called some challenging market conditions. Pre-tax profits rose 14% to 15.7m pounds, wiping out last years 3m pounds drop in profits, and revenue rose 4% to 113m pounds. The news follows up-beat remarks at the interim stage and cash flows were also much stronger than in the prior year. The group’s sensors division had a record year while the components division, which grew less strongly, saw a marked recovery from the instability of 1996. Operating margins improved by one and a half points to 14.6% and summing up, newly appointed chairman Sir Alan Cockshaw stated that it had been an excellent year. The full dividend for the year is up 11% at 7.3 pence.
