Shares in the 3G mobile broadband equipment maker have bounced nearly 14 per cent since hitting a six-month low of 18¢ on Monday after management gave a revised earnings guidance for the year to June 30, 2011. While management lowered the sales forecast to between $71 million and $87 million from guidance of $100 million to $116 million in August, it kept its earnings before interest and tax forecast of $8 million to $13 million – more than double what it made last year. The result was driven by a change in product mix to lower-turnover but higher-margin equipment. This reduction in sales intensity will not hurt earnings, which means that NetComm is operating more efficiently.
