Viacom - Viacom earned $1.21 per share for the fourth quarter, excluding certain items, four cents above estimates. Revenue was slightly light, in part because of a drop in filmed entertainment revenues.
PetSmart - The pet supplies retailer reported third-quarter profit of $0.75 per share, 12 cents above estimates. Same-store sales were up a better-than-expected 6.5 percent for the quarter. The company also raised its earnings guidance for the year.
Diamond Foods – Diamond completed a restatement of its first three quarters of 2012, following an internal probe that highlighted errors in accounting for payments to walnut growers. Its restatement resulted in a loss for the three quarters, as well as cutting the snack maker's earnings by 57 percent for 2011 and by 46 percent for 2010.
NetApp – The company earned $0.51 per share, excluding certain items, for its fiscal second quarter, three cents above estimates. Its current-quarter forecast is also slightly ahead of Street estimates, and the maker of data storage equipment said it will buy back another $1.5 billion in stock.
Limited Brands – Limited earned $0.26 per share, excluding certain items, for its third quarter, two cents above estimates. The retailer also raised its full-year forecast and has authorized a new $250 million share repurchase program, but its revised guidance remains short of Street estimates. Limited's results were driven by upbeat sales at its Victoria's Secret and Bath & Body Works divisions.
GlaxoSmithKline - A U.S. Food and Drug Administration panel has recommended approval of Glaxo's H5N1 influenza vaccine. The FDA is not required to follow the recommendations of its panels, but usually does so. The vaccine is already approved for use in the European market.
News Corp. – The media giant is reportedly close to a deal to buy a minority stake in the YES regional sports network, according to The Wall Street Journal. The deal would value the network, which televises New York Yankee games, at about $3 billion, with News Corp. acquiring a 40 percent stake.
Williams-Sonoma - The home goods retailer earned $0.45 per share for the third quarter, four cents above estimates, with revenue also beating consensus. However, its current-quarter guidance is short of what the Street was expecting.
