The average estimate of analysts polled by

was for a loss of 11 cents a share in the quarter.

"Sales and profitability have been tougher than anticipated during the first 13 weeks, but the transformation is ahead of schedule," said Johnson in a press release.

surged in late trades after the China-based company reported non-GAAP earnings of $4.5 million, or 13 cents a share, on revenue of $169.3 million, up nearly 70% from last year.

Jeffrey Kang, Cogo's CEO and chairman, also said the company's audit committee continues to review his proposal to buy "certain assets, liabilities and operating business units" with the process expected to be completed by the end of the second quarter.

"Target companies of the deal roughly account for 26% of the group's revenue, with a gross margin of approximately 5% in the first quarter of 2012," Kang said in a press release.

"Although we expect macroeconomic headwinds to continue into the second quarter, we have begun test trials of Weibo brand advertising, which is powered by a social interest graph recommendation engine, and expect this new product offering to have a meaningful impact on our brand advertising business in the second half of this year."
