Market Insider | What's Shaking | Earnings to Watch | Before the Bell

Check out which companies are making headlines before the bell on Wednesday:

Comcast – The NBCUniversal parent earned 65 cents per share for the third quarter, four cents above estimates, though revenue was slightly shy of consensus. Free cash flow reached record levels during the quarter, and CEO Brian Roberts points out that the year-ago quarter got an extra boost from the Summer Olympics.

General Motors – The automaker reported third quarter profit of 96 cents per share, excluding certain items, beating estimates by two cents, though revenue was slightly short of consensus.

Garmin –The maker of GPS devices earned 69 cents per share for the third quarter, ten cents above estimates, with revenue also beating consensus. Garmin saw improved results in its aviation and fitness-related product lines.

Corning – Corning earned 33 cents per share for the third quarter, a penny above estimates, with revenue in line with forecasts. Gross margins increased, though Corning was affected by a moderate drop in LCD glass prices.

Automatic Data Processing – The payroll services provider beat consensus by two cents with fiscal first quarter earnings of 68 cents per share, and revenue also came in slightly above estimates. ADP results were helped by improvement in the U.S. job market.

Southern Co. – The utility earned $1.08 per share for the third quarter, excluding certain items, three cents below estimates, with revenue short as well. The company's bottom line was hurt by excessive rainfall and cooler than normal temperatures.

Nike – Morgan Stanley upgraded the athletic footwear and apparel maker's stock to "overweight" from "equalweight", citing the potential for an acceleration in earnings growth. The firm said the power of Nike's balance sheet is not properly understood by the Street.

Bed Bath & Beyond – Cannacord downgraded the retailer's stock to "hold" from "buy", citing a difficult retail climate.

Electronic Arts – EA reported second quarter profit of 33 cents per share, excluding certain items, beating estimates by 20 cents. Revenue was also above estimates, and the game maker raised its full-year outlook ahead of the release of new video game consoles. However, EA's current quarter earnings and revenue estimates are short of analyst forecasts.

Yelp – Yelp lost four cents per share for the third quarter, excluding certain items, wider than the one cent loss analysts were anticipating. However, the review site operator's revenue and current quarter estimates are above Street consensus. Yelp's bottom line has been impacted by increased marketing expenses, but it did raise its full-year revenue outlook.

LinkedIn –The business networking site operator earned 39 cents per share, excluding certain items, for the third quarter, beating estimates by seven cents, and also saw revenue come in above forecasts as well. Its current quarter revenue forecast, however, is below Street forecasts, despite a jump in the number of users this year.

Buffalo Wild Wings – Buffalo Wild Wings reported third quarter profit of 95 cents per share, ten cents above estimates, with revenue beating analyst forecasts as well. The restaurant chain benefited from lower prices for chicken wings, and also saw a 4.8 percent increase in same-store sales at company-owned locations, as well as a 3.9 percent rise at franchises.

Shutterfly – Shutterfly lost 24 cents per share for the third quarter, excluding certain items, smaller than the 60 cent loss analysts were expecting. Revenue was above consensus, but the photo sharing service's current quarter EPS and revenue estimates fall well below analyst estimates.

DreamWorks – The movie studio earned 12 cents per share for the third quarter, surprising analysts who had forecast a break-even quarter. Revenue came in above expectations, and investors appear relieved that the profit drop of 59 percent from a year earlier wasn't as large as some had thought.

IAC/Interactive– IAC reported third quarter profit of $1.29 per share, excluding certain items, well above estimates of 95 cents. Revenue fell short of forecasts, despite growth from the company's dating sites like Match.com.

Take-Two Interactive – Take-Two beat estimates by a wide margin, earning $2.49 per share for its second quarter compared to estimates of $1.71. Revenue trounced estimates, and current quarter revenue estimates for the video-game maker are above forecasts as well. The company's results were helped by the popularity of the newly-released "Grand Theft Auto V".

Gilead Sciences – The biotech company reported third quarter profit of 52 cents per share, excluding certain items, four cents above estimates. Gilead also raised its full-year sales guidance, thanks to good results for its line of HIV drugs.

Baidu – China's leading internet company beat estimates for the third quarter with its latest results, and also gave an upbeat current quarter forecast.

Caesars Entertainment– Caesars lost $6.03 per share for the third quarter, much wider than the $1.29 per share loss forecast by analysts. Revenue was also below consensus, as the casino operator saw weakness in its U.S. operations.

Aflac – Aflac earned $1.47 per share for the third quarter, missing estimates by one cent. However, the insurance company did say it would buy back more stock in 2014 than it had previously anticipated.
