Raster Graphics Inc, San Jose-based maker of digital printing systems, says that, based on preliminary analysis, net revenue for the first quarter will be significantly below planned levels, and should come in between $9m and $10m, down from $12.6 in the year-ago period. The shortfall should leave the company with a pre-tax loss of $4.5m to $5m, against net income of $1.1m a year ago. The company offered a host of reasons for the shortfall, including weak revenue from certain geographic markets – mainly the US and Germany – decreased gross margins, increased operating expenses, restructuring charges associated stemming from headcount reduction and increased reserves. The company also says it’s retained the services of an investment bank with a view towards evaluating potential strategic partners. It’s not clear whether Raster is up for sale or it’s just looking for a financing deal, as the company could not be reached for comment.
