Wind River Systems Inc’s share price recovered to just below its all time high on Wednesday as the Alameda, California-based provider of real-time operating systems turned in a convincing set of first quarter results. Net profits are up 100.7% to $3.0m on revenue that rose 46.0% to $18.4m. The shares took a huge tumble back in April this year but, since May, Wind River has mounted a recovery, with shares trading around the $34 mark on Thursday. The company says it now has around 9,000 customers for its Tornado real-time development environment for Unix and Windows, and has just released its second maintenance and enhancement release. It added 44 new staff in the quarter. Wind River is also riding off the back of the developing I20Intelligent Input-Output standard (CI No 3,120), and has customized Tornado for I20 products via the first I20 implementation of its IxWork real-time operating system, announced earlier this month. It says American Megatrends Inc, SuperMicro Inc and Hewlett-Packard Co have come to it for I20- related products. Also in the quarter, Lucent Technologies Inc selected Wind River’s VxWorks embedded operating system for use in its next generation digital switches.
