Check out which companies are making headlines before the bell on Thursday:
Smithfield Foods - The largest pork processor reported fiscal third-quarter profit of $0.58 per share, and $0.69 when certain items are excluded, compared to estimates of $0.50 a share. A rise in sales of packaged meats helped offset a decline in sales of fresh pork.
Dell - Dell has responded to new shareholder Carl Icahn's demand for a leveraged recapitalization and a $9 a share special dividend if the current proposed buyout deal is voted down by shareholders. Dell said it is engaged in an active "go-shop" process for alternative proposals, and that it welcomes Icahn's involvement.
PetSmart - The company reported fourth-quarter profit of $1.24 per share, three cents a share above estimates, as sales and profit margins grew. However, the pet supplies retailer is forecasting 2013 profit of $3.76 to $3.92 per share, below estimates of $3.93 a share.
