Check out which companies are making headlines before the bell:
Lululemon—The yoga wear maker reported quarterly profit of 42 cents per share, 4 cents above estimates, though revenue was slightly short of consensus. The company also saw comparable sales come in better than expected, thanks to a jump in online orders.
Dominion Resources—Citi added the stock to its focus list, resuming coverage with a "buy" rating. Citi said the energy producer and transporter has a very bright cash flow outlook not yet fully appreciated by investors.
Ciena—The maker of networking equipment posted an adjusted quarterly loss of 8 cents per share, compared to forecasts of a 12-cent per share profit. Revenue was above estimates, but Ciena's bottom line was hurt by a significant drop in profit margins.
RadioShack—The electronics retailer posted a bigger-than-expected quarterly loss, and saw revenue and same-store sales fall short of estimates as well. It unveiled new cost-reduction initiatives and said its retail business is showing signs of recovery.
Staples—Activist investor Starboard Value took a 5.1-percent stake in Staples, and also raised its stake in Office Depot to 9.9 percent. Analysts say Starboard could push for a combination of the two office supply retailers.
Wal-Mart—The retailer said it discovered accounting discrepancies in its China operations, and that it has reinforced its compliance policies. That follows a Bloomberg report saying Wal-Mart's China accounting practices made its results in that country seem stronger than they were.
Walgreen—CEO Greg Wasson will retire after the completion of the drugstore chain's deal to buy Alliance Boots. Alliance Boots executive chairman Stefano Pessina will become acting CEO as a search is conducted for a permanent replacement.
Restoration Hardware—The company beat estimates by 1 cent with adjusted quarterly profit of 49 cents per share, with revenue also above consensus. Following a surge in sales growth in the third quarter, the home goods retailer raised its earnings forecast for the full year.

EBay—The online marketplace is reportedly considering cutting thousands of jobs in early 2015, ahead of planned separation of its PayPal unit. The Wall Street Journal reports the cuts would likely come from eBay's core marketplace operations.
Johnson Controls—The company cut CEO Alex Molinaroli's bonus by 20 percent after determining that he violated the auto parts maker's ethics policy. An SEC filing said Molinaroli failed to disclose an extramarital affair with a company consultant.
