Take-Two's third-quarter profit soared on a 76% increase in revenue, thanks in part to a record-breaking release of a basketball game. In addition, the New York game maker authorized the repurchase of up to 7.5 million shares. Take-Two shares jumped 6.6% after hours to $13.49.

Shutterfly's fourth-quarter earnings jumped 50% as the photo sharing and printing website operator's sales and margins improved. Shares climbed 14% to $38.35 after hours as results topped Shutterfly's estimates and as the company provided full-year revenue guidance above analyst expectations.

Expedia Inc.'s (EXPE) fourth-quarter profit slumped 90% as the online travel agent reported a large legal reserve, masking stronger revenue. However, shares rose 4.9% to $70.78 after hours as revenue beat analysts' expectations.

   Regular-Session Gainers 
 

Aecom Technology Corp.'s (ACM) fiscal first-quarter earnings topped analysts' expectations despite sliding 20% as weakness in Australia and the U.S. hurt the technical and management-support services provider's sales and margins.

Archer Daniels Midland Co.'s (ADM) fiscal second-quarter earnings surged as the agricultural giant operated U.S. soy-crushing plants at a record capacity in the quarter.

Cache Inc. (CACH) said Chairman and Chief Executive Thomas Reinckens is stepping down and will be succeed by industry veteran Jay Margolis, as the women's apparel company also said shareholders MFP Partners and Mill Road plan to appoint two representatives to the retailer's board. In addition, Cache projected fourth-quarter net sales that were slightly higher than analysts' views.

Centene Corp. (CNC) felt a worse-than-expected impact from a bad flu season in the fourth quarter, and Chief Executive Michael Neidorff said the Medicaid insurer's initial read suggests similar flu costs in January as was the case in December. But Centene had anticipated costs for the virus would be higher sequentially this quarter and Mr. Neidorff noted recent CDC data suggests the flu season peaked in mid-January. "Recognizing this, we have not changed our annual guidance," he said. Some analysts are viewing the maintained guidance as a positive sign against the backdrop of big fourth-quarter hit.

Computer Sciences Corp. (CSC) swung to a fiscal third-quarter profit as the technology-products distributor started to see benefits from its turnaround efforts. Margins more than doubled in the North American public-sector segment, even as revenue fell 2.8%.

Shares of Eaton Corp. (ETN) rose despite forecasting downbeat current-quarter income and reporting lower fourth-quarter earnings as weaker international electrical sales and acquisition costs masked the power-management-systems maker's improved revenue. However, the company has said it could benefit from a boost in demand for transformers, switching gear and other electrical equipment caused by superstorm Sandy, which devastated New Jersey, New York and nearby areas in October. Eaton in November closed on its roughly $11.8 billion acquisition of Cooper Industries and is poised to vastly expand its power-management portfolio and electrical business.

Estee Lauder Cos.'s (EL) fiscal second-quarter earnings rose 13% as the beauty-products company reported higher revenue, boosted by accelerated orders from some retailers. The company, home to brands such as Clinique and Origins as well as its namesake line, also raised its profit forecast for the year.

Opexa Therapeutics Inc. (OPXA) stands to be awarded up to $225 million in a commercialization deal struck with Merck KGaA's (MKGAY, MRK.XE) for Opexa's multiple-sclerosis therapy, Tcelna. Opexa's shares traded more than two times higher.

Circuits supplier Power Integrations Inc. (POWI) turned in better-than-expected fourth-quarter results, helped by a 50% jump in LED lighting revenue. "While peers are guiding down due to cyclical weakness in end-market demand, [Power Integrations] is outperforming," Sterne Agee said in a note, backing its buy rating on the stock.

Protalix BioTherapeutics Inc. (PLX) confirmed it is exploring strategic options, although it didn't specify as to whether these include the possibility of selling itself.

Regal-Beloit Corp. (RBC) shares continued to rise after its fourth-quarter results surpassed expectations and its current-quarter earnings guidance was also above Wall Street's view.

John Malone's international cable business Liberty Global Inc. (LBTYA) is close to a deal to buy U.K. cable-television and Internet provider Virgin Media Inc. (VMED), which could create a stronger competitor to market leader British Sky Broadcasting Group PLC (BSYBY, BSY.LN, BSV.LN). Virgin Media shares jumped in regular session trading.

 
  Regular-Session Decliners

BRE Properties Inc.'s (BRE) $2.40-a-share midpoint guidance for 2013 funds from operations was below analysts' expectations, weighing on shares, despite its fourth-quarter earnings more than doubling on same-store revenue growth and a gain on property sales.

Diamond Offshore Drilling Inc.'s (DO) fourth-quarter earnings fell 17% as lower day rates dampened improved utilization of ultradeep-water and midwater floaters, although results topped consensus estimates. Dahlman Rose and Co. and GHS Research said in analyst notes that 2013 downtime estimates by the company were higher than expected.

While Edwards Lifesciences Corp. (EW) beat analysts' expectations with its fourth-quarter results, investors are focused on U.S. sales of its Sapien heart valve. Nearly 20% came from healthcare-provider "stocking," or buying devices in anticipation of use. That is higher than expected, Wells Fargo said, and suggests somewhat lower Sapien utilization than anticipated.

Hemispherx Biopharma Inc. (HEB) said the U.S. Food and Drug Administration has declined to approve a proposed treatment for chronic-fatigue syndrome, saying the company didn't provide sufficient safety or efficacy data. The drug, Ampligen, has been in development for more than two decades. Shares sank after hours Monday, and continued to decline in recent trading.

Citigroup downgraded Iconix Brand Group Inc. (ICON) to neutral from buy based on valuation and lack of near-term catalysts, after the company said it acquired a 51% stake in the Buffalo David Bitton brand for $76.5 million. With the stock up historically, Citigroup believes the Buffalo and Umbro acquisitions are now priced in.

Rudolph Technologies Inc.'s (RTEC) fourth-quarter profit surged on tax-related adjustments and higher revenue. Shares fell, however, as the results missed Street expectations.

Yum Brands Inc.'s (YUM) fourth-quarter earnings slipped 5.3% as the fast-food chain's same-store sales in China were hurt by negative publicity from a government review of poultry supplies there. The company also said it no longer expects earnings growth this year.
