Check out which companies are making headlines before the bell on Wednesday:
Comcast —NBCUniversal's parent company reported second quarter profit of 65 cents per share, two cents above estimates, with revenue beating consensus as well. Its results were helped by stronger growth in high speed internet customers.
Humana — The health plan provider earned $2.63 per share for the second quarter, beating estimates of $2.47, and raised its guidance for the year on strong growth in membership levels.
Energizer Holdings —The battery maker increased its quarterly dividend by 25 percent to 50 cents per share from 40 cents.
Hyatt Hotels —The hotel operator earned 43 cents per share, excluding certain items, for the second quarter, beating estimates by 13 cents, as strong U.S. demand helped push room rates higher.
SodaStream —The maker of home soda systems earned 74 cents per share for the second quarter, excluding certain items, beat Street estimates by 18 cents. The company said it is encouraged by operating income that's growing faster than revenue.
Delphi Automotive — The auto parts maker earned $1.24 per share for the second quarter, ten cents above estimates, but gave downbeat guidance for the current quarter.
ADT —The security products maker earned 53 cents per share for the second quarter, nine cents above estimates, on the strength of sales growth and cost controls.
Garmin —Garmin posted second quarter profit of 76 cents per share, 11 cents above estimates, with revenue beating consensus by a wide margin. Garmin did warn that declines in its personal navigation device market will continue to be a headwind.
Facebook — Facebook came within four cents Tuesday of equaling its IPO price of $38 for the first time since its debut in May 2012.
Symantec —Symantec reported first quarter profit of 44 cents per share, eight cents above estimates, with revenue also above consensus. The maker of Norton anti-virus software saw increased sales following a series of high profile hacking attacks.
Amgen — Amgen reported second quarter profit of $1.89 per share, excluding certain items, beating estimates by 15 cents. Revenue exceeded forecasts, and the biotech giant also sees full year profit above street estimates.
Buffalo Wild Wings — The restaurant chain beat estimates by nine cents, earning 88 cents per share for the second quarter. But the stock is under pressure on investor concern about slowing same-store sales growth.
IAC/InterActiveCorp — IAC earned 95 cents per share, excluding certain items, for the second quarter, beating estimates by a penny. Revenue outdistanced forecasts, as revenue from Match.com increased.
Aflac —Aflac earned $1.62 per share for the second quarter, excluding certain items, 11 cents above estimates, with revenue beating consensus, as premium growth for its Japanese unit improved. However, the life insurer's current quarter forecast is below Street forecasts.
Take-Two Interactive — The video game maker lost 54 cents per share for its first quarter, a slightly smaller loss than the 57 cent number forecast by analysts.

Genworth Financial — Genworth earned 27 cents per share for the second quarter, missing estimates by two cents, with revenue falling short as well. Genworth said its U.S. mortgage insurance business will likely post a loss for the second half of the year.
