Gainers

Oclaro, Inc. (OCLR) stock jumped 12.24 percent to $3.30 in after-market trading. The company provided additional details about the progress of the company's recovery efforts from the flooding in Thailand. The company said it currently expects four of the five flood affected product lines to have restarted commercial output at Fabrinet's Pinehurst facility by the end of January. The company also raised its second quarter preliminary revenue guidance to about $86 million from the previous forecast of $75 million to $85 million, while Street predicts $80.69 million. Oclaro currently expects capital expenditures of about $6 million in each of the second and third fiscal quarters. Commercial shipments of WSS products are expected to begin at the end of the March quarter and production capacity is expected to return to pre-flood levels in the June quarter.

Zumiez Inc. (ZUMZ) stock climbed 10.75 percent to $29.16 in after-market trading. The company said Wednesday that its comparable store sales for December month increased 10.0 percent. Sales for the month grew 18.1 percent to $104.6 million. Looking ahead into the fourth quarter, the company raised its earnings guidance to range of $0.57 to $0.58 per share from previous forecast of $0.52 to $0.54 per share. The company also increased its fourth quarter sales outlook to range of $180 million to $181 million from previous range of $174 million to $177 million. Street analysts currently predict profit of $0.52 per share on revenue of $176.81 million for the fourth quarter.

National Instruments Corp. (NATI) stock grew 8.77 percent to $26.37 in after-market trading. The shares closed Wednesday's regular trading down 7.05 percent at $24.51 after the company slashed its fourth quarter guidance, Tuesday after the market close, due to reduced demand for its measurement and automation products in crisis-hit Europe.

Seagate Technology (STX) stock gained 8.13 percent to $18.07 in after-market trading. The company said it raised its second quarter revenue to range of $3.1 billion to $3.2 billion from previous forecast of $2.8 billion, while Street predicts $2.81 billion. Seagate said it shipped 47 million disk drives in the second quarter, higher than its guidance of about 43 million units provided at the end of November. The shipments include about 700,000 Samsung disk drives after Seagate closed the acquisition of Samsung Electronics Co. Ltd's hard disk drive business on Dec. 19. Gross margin as a percent of revenue for the second quarter is expected to be at least 30.5 percent, compared to the maximum 29 percent forecast earlier. The estimate does not include charges related to the acquisition of Samsung's hard disk drive business.

Seagate expects pricing to remain stable in calendar 2012, backing its prior view that demand would exceed supply in 2012. Late November, the company had anticipated significant constraint of hard disk drive supply for several quarters. For the third quarter, excluding costs related to Samsung, Seagate expects shipments to be higher than the second quarter. The company increased its third quarter revenue guidance to range of $4.2 billion to $4.5 billion from previous forecast of at least $3.75 billion, while Street predicts $3.62 billion. The company also lifted its third quarter gross margin outlook to at least 33 percent from previous forecast of maximum of 29 percent.

Losers

DryShips Inc. (DRYS) stock declined 2.68 percent to $2.18 in after-market trading.

Savient Pharmaceuticals Inc. (SVNT) stock decreased 2.53 percent to $2.31 in after-market trading.

Sonic Corp. (SONC) stock declined 2.19 percent to $6.70 in after-market trading. Profit for the first quarter was $5.5 million or $0.09 per share, down from $7.2 million or $0.12 per share last year. Revenue moved down 0.7 percent to $128.3 million. Analysts had expected profit of $0.09 per share on revenue of $129.87 million. Looking ahead, the company expects its initiatives to drive sales improvements; however, uncertainty with regard to the external environment and its impact on consumer confidence may result in continued sales volatility. The fiscal second quarter is seasonally Sonic's lowest in sales volume and most volatile period, as it is more susceptible to adverse weather conditions.

Summit first deployed ZixCorp solutions in 2003 to protect patient data in external email communication and meet the compliance requirements of the Health Insurance Portability and Accountability Act (HIPAA). In its third renewal, Summit continues to select ZixCorp solutions based on its reliable technology and user convenience.
