Check out which companies are making headlines before the bell on Thursday:
Facebook - The social network operator reported fourth-quarter profit of $0.17 per share, two cents above estimates, with revenue slightly above consensus. Facebook also doubled its mobile advertising from the prior quarter, although that fell short of some of the most optimistic analyst estimates.
Dow Chemical - The chemical maker earned $0.33 per share for the fourth quarter, one cent below estimates, though revenue did beat consensus. The company said it saw significant deterioration in markets it serves, especially China, during the second half of the year.
Whirlpool - The appliance maker earned $2.29 per share for the fourth quarter, excluding certain items, six cents above estimates. Higher prices for its products helped the bottom line, along with cost cutting measures.
Dunkin' Brands - The restaurant operator earned $0.34 per share, excluding certain items, for the fourth quarter, one cent above estimates. It also raised its quarterly dividend to $0.19 per share from $0.15. Its results were helped by a better-than-expected 3.2 percent increase in same-store sales.
Qualcomm - Qualcomm earned $1.26 per share for its fiscal first quarter, 13 cents above estimates, with revenue beating estimates, as well. The chipmaker also issued better-than-expected guidance for the current quarter, as inventories have been built back up to sufficient levels following shortages last year.
Under Armour - The athletic apparel maker earned $0.47 per share for the fourth quarter, one cent above estimates, with revenue also above consensus, as the company enjoyed upbeat holiday sales.
Hershey - The chocolate maker fell short of estimates by two cents with fourth-quarter profit of $0.74 per share. The company did raise its full-year guidance for 2013, however, as it reported strength in all its product categories.
Colgate-Palmolive - The consumer products maker earned $1.41 per share for the fourth quarter, one cent above estimates. Colgate benefited from higher prices, and an ad campaign that attracted more shoppers.
Citrix Systems - Citrix earned $0.90 per share for its fourth quarter, six cents better than consensus. Revenue was above estimates, as is the business software maker's revenue estimates for the current quarter. The upbeat report followed cautious comments back in October, when Citrix highlighted weak spending by the U.S. government and economic uncertainty in overseas markets.
Electronic Arts - EA earned $0.57 per share for its third quarter, one cent above estimates, though revenue fell below forecasts. The videogame maker did forecast weaker-than-expected revenue for the current quarter, with EA noting weaker-than-expected sales of its "Medal of Honor: Warfighter" game and the end of the current console cycle.
Las Vegas Sands - The casino operator earned $0.54 per share, excluding certain items, for its fourth quarter, five cents below estimates. But revenue beat forecasts, and growth in the China market more than made up for declines in Las Vegas and Singapore.
JDS Uniphase - JDS beat estimates by four cents for its second quarter with per-share earnings of $0.18. The maker of fiber optic components also saw revenue top estimates, as well as a rise in profit margins.
Skyworks Solutions - Skyworks reported fiscal first-quarter profit of $0.55, one cent above estimates, with revenue also above consensus. Skyworks, a supplier to Apple, saw demand jump for its chips that are used to connect cellphones to networks.
ConocoPhillips - The company earned $1.43 per share, excluding certain items, for the fourth quarter, one cent above estimates. The energy producer's profits did drop from the prior year on weaker oil and gas prices.
STMicroelectronics - STMicro lost $0.11 per share for the fourth quarter, excluding certain items, a smaller loss than the $0.12 analysts were expecting. The chipmaker's revenue was essentially in line with estimates, though the company said it continues to see softness in the semiconductor market.
Diageo - The company said its net profits rose 61 percent for the six months ending Dec. 31, thanks to higher prices and strong sales in America. Diageo is the maker of the Johnny Walker, Smirnoff, and Guinness alcoholic beverage brands.
