Unlisted Securities Market counter, systems house and Texas Instruments reseller Radius Plc of Hull is bubbling with pre-tax profit up 40% on sales up 37.5% for the year to November 30 (see below). The company attributed its strong performance to its switch to Unix products with the focus on vertical markets. What has proved to be a winning formula for Radius was in large measure created by Texas Instruments’ decision to abandon its proprietary operating system in favour of Unix. This forced Radius to diversify by acquiring two Unix specialists last year Amstrong Micro Electronics Ltd for UKP500,000 and Advanced Business Technology Ltd – also a Data General reseller – for a nominal sum – and building up Unix expertise. Now Radius is committed to continuing to expand by organic growth and acquisition of firms with vertical market software and systems. Radius also has a 5.4% stake in the listed Altos Computer and Wyse Techno.lh 6 logy distributor Logitek Plc as an investment.
