Check out which companies are making headlines before the bell:
Hershey—The chocolate maker earned $1.05 per share for the third quarter, 3 cents below estimates, with revenue essentially in line. The company said net sales exceeded its own forecasts, and it also saw an increase in market share. Hershey also lowered its guidance for the year due to lower-than-expected international sales.
Garmin—The maker of GPS devices earned an adjusted 76 cents for the third quarter, 5 cents above estimates, and revenue scored a solid beat over analyst forecasts. Garmin's full-year forecast is also above Street estimates, as it sees growth in its non-automotive/mobile segment.
WellPoint—The health insurer reported third quarter profit of $2.36 per share, 9 cents above estimates. Revenue was below forecasts, but WellPoint raised its 2014 forecast on the basis of a growing customer base.
Sanofi—The drug maker's board of directors has removed Christopher Viebacher as chief executive officer, and appointed chairman Serve Weinberg as interim CEO. Sanofi plans to separate the jobs of chairman and chief executive officer once again when it appoints a permanent CEO.
SodaStream—The company reported third quarter profit of 45 cents per share, 6 cents above estimates, but revenue fell below consensus forecasts. The maker of home soda machines said its performance was impacted by "challenging selling conditions," primarily in the U.S.
Automatic Data Processing—The payroll processor reported fiscal first quarter profit of 62 cents per share, 2 cents above estimates, with revenue essentially in line. The results were helped by new recurring revenue in ADP's Human Capital Management business.
Eaton Corp.—The diversified manufacturer beat estimates by 6 cents with third quarter profit of $1.29 per share, although revenue was slightly shy of Street forecasts. Increased sales in its electrical and aerospace business helped Eaton's results.
STMicroelectronics—Europe's largest chip maker is seeing its shares come under pressure, after it said profit margins would be flat and revenue would decline during the year's final quarter.
Facebook—The social network's latest quarterly earnings were 3 cents above estimates at 43 cents per share, and revenue also beat consensus forecasts. However, Facebook also said revenue growth would slow this quarter and that spending would increase significantly in 2015.
Gilead Sciences—The company beat estimates by 13 cents with adjusted quarterly earnings of $2.05 per share, while revenue exceeded forecasts as well. That comes despite lower than expected sales of its hepatitis C treatment Sovaldi.
Electronic Arts—The video game publisher scored a 20 cent beat with an adjusted quarterly profit of 73 cents per share, with revenue also above consensus. EA also raised its 2015 forecast as it cuts expenses and sees strong sales of its FIFA and Madden titles.
Express Scripts—The company matched estimates with an adjusted quarterly profit of $1.29 per share, while revenue came in above analyst forecasts. The pharmacy benefits manager saw better profit margins during the quarter, and it also narrowed its profit forecast for the full year.
Deutsche Bank—The bank has reassigned chief financial officer Stefan Krause, naming Goldman Sachs executive Marcus Schenk as its new CFO.
Marriott—The hotel operator reported quarterly earnings of 65 cents per share, beating estimates by 3 cents. Marriott also raised its earnings forecast for the year as its revenue per available room and average daily rates rise by a healthy margin.
Panera Bread—The restaurant chain reported quarterly profit of $1.46 per share, 4 cents above estimates, but Panera also cut its fourth quarter and full-year guidance. Panera's profit margins have been hurt by higher costs for ingredients, as well as investments in new ways to speed its service.
Western Digital—The hard disk drive maker beat estimates by 7 cents, reporting adjusted quarterly profit of 7 cents per share. Revenue was above estimates as well, as businesses increase spending on computer upgrades.
Anadarko Petroleum—The oil and gas exploration company came in 11 cents shy of estimates, with quarterly profit of $1.16 per share, even though revenue was above consensus. Anadarko did raise its full-year output forecast, and continues to sell assets with lower returns.
Wynn Resorts—The hotel and casino operator beat estimates by 11 cents, earning an adjusted $1.95 per share for its latest quarter. Wynn did see losses in Macau, but those were offset by higher profits in Las Vegas.
Orbital Sciences—The company's unmanned Antares rocket exploded a few seconds after liftoff in Virginia. The rocket was intended to carry supplies to the International Space Station.
Delta Air Lines—The company is the subject of a Transportation Department probe, after a complaint by local officials and a private group that the airline used "unfair and deceptive practices" to block a new major airport near Atlanta.
