The optical-networking-parts maker posted a net loss of $11.9 million, or 28 cents a share, for the quarter ended Dec. 31. Excluding one-time items, Bookham's pro forma net loss was 19 cents a share. Sales rose to $60.7 million from $45.8 million in the year-ago period but fell from $62.6 million in the prior quarter.

Analysts were looking for an adjusted loss of 18 cents a share on sales of $59.4 million in the most recent quarter.

Wall Street had been looking for a smaller decline, with revenue estimates around $58 million, according to Reuters Research.

"On the operations front, we continued to make significant progress moving our assembly and test operations to Shenzhen, China," CEO Dr. Giorgio Anania said in a press release Thursday.

Bookham shares were whipsawed Thursday, closing the regular session up 12% before falling 90 cents to $6.90 in postclose trading.
