Take a look at some of Monday's morning movers:
Lowe's - The home improvement retailer reported third-quarter profit of $0.40 per share, excluding certain items, five cents above estimates. Revenue and same-store sales also exceeded consensus.
Tyson Foods - The food producer earned 55 cents per share for its fiscal fourth quarter, excluding certain items, 11 cents above estimates. Tyson has also declared a special dividend of 10 cents per share, and increased its regular quarterly dividend to 5 cents per share from four cents.
Republic Services - Cascade Investments increased its stake in the waste management company to 23 percent. Cascade is the investment company that manages the bulk of Microsoft Chairman Bill Gates' wealth.
eBay - The company is the target of a U.S. Justice Department lawsuit, which charged the online auction company with violating antitrust laws. The DOJ said eBay entered into an agreement not to recruit or hire employees from Intuit, with former eBay CEO Meg Whitman and Intuit founder Scott Cook heavily involved in formulating that agreement.
Yahoo - CEO Marissa Mayer is reportedly ending the company's practice of giving most employees the week off between Christmas and New Year's Day. All Things D reports that this is not necessarily an unpopular move within Yahoo, given the challenges that the company faces.
HSBC - The bank is in talks to sell its 15.6 percent stake in China insurer Ping An. The stake is currently worth approximately $9.3 billion.
Cisco Systems - Cisco is buying San Francisco-based Meraki for $1.2 billion. Meraki is a provider of various forms of cloud computing technology, and the company will be the basis of Cisco's new Cloud Networking group.
BP - BP will spend up to $5.9 billion buying back stock, according to London's Sunday Times. That follows last week's agreement to pay record criminal penalties related to the massive 2010 Gulf oil spill.
Monsanto - The company says the Justice Department has ended its antitrust probe of the seed industry in general and its soybean genetic traits business in particular. Monsanto had been the target of complaints saying it was trying to limit access to older, cheaper products to push a new, more expensive offering.
E*Trade Financial - The online broker is shutting down its British brokerage business, according to The Wall Street Journal, so it can concentrate on its U.S. operations.
Best Buy - CEO Hubert Joly will meet with founder Richard Schulze this week, according to the Minneapolis Star Tribune. The two will discuss Schulze's offer to buy the electronics retailer.
Facebook, Yahoo - The two may or may not be in talks about a potential search-related collaboration. London's Sunday Telegraph reports such talks have taken place, but All Things D says the report is incorrect and that Yahoo isn't anywhere near cutting off its current partnership with Microsoft.
Diamond Foods - The stock has been downgraded to "underperform" from "hold" at Jefferies, following the food producer's restatement of earnings and what it calls a lack of earnings visibility.
Rambus - The chipmaker's shares have been upgraded to "overweight" from "neutral" at JPMorgan Chase.

Computer Sciences - Deutsche Bank has upgraded the stock to "buy" from "hold" following a meeting with the company's new management, which indicated that a turnaround at is happening faster than initially expected.
