EFJ(EFJI) tumbled 16% after the wireless telecom-systems company posted fourth-quarter results that fell well below expectations. The company reported a loss of $7.8 million, or 30 cents a share, on revenue of $23.9 million. Analysts expected a loss of 8 cents a share on revenue of $31.3 million. During the year-earlier period, the company posted a profit of $15.4 million, or 59 cents a share, on revenue of $29.8 million.

EFJ blamed the revenue decline on lower revenue in its wireless business segment. "Our private wireless business segment was much softer than anticipated," the company said. "This was due to market delays in shipping rebanding orders, shifts in product mix and unanticipated outsourcing issues which delayed our launching of new improved products."

Looking ahead, EFJ sees 2007 operating income of $7 million to $10 million on revenue of $185 million to $195 million. Analysts project earnings of 46 cents a share on revenue of $193 million. Shares were trading down $1.03 to $5.36.
