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

Facebook shares were down more than 2 percent in choppy trade after the company's earnings easily surpassed expectations. The social-media giant beat on both its top and bottom lines Wednesday, as it added more users than Wall Street expected. The social media giant posted adjusted earnings of $1.09 per share on revenue of $7.01 billion, up from the comparable year-ago figures of 57 cents per share, adjusted, on $4.5 billion in revenue.

Advertising revenue hit $6.82 billion, above the $6.71 billion estimated by StreetAccount. Monthly active users rose to 1.79 billion, above the more than 1.75 billion expected. For the first time, more than 1 billion users were active only on their phones every month. Average revenue per user was $4.01 in the third quarter.

American International Group saw its stock fall more than 3 percent after its quarterly earnings report. The insurance company posted adjusted earnings of $1 a share, which is not comparable to estimates of $1.21. The AIG board of directors also authorized the repurchase of additional shares with an aggregate purchase price of up to $3 billion.

Qualcomm shares ticked down slightly in choppy trade, following the chipmaker reporting earnings after the bell Wednesday. The company posted earnings of $1.28 a share, beating EPS estimates of $1.13. It also beat on its top line, reporting revenues of $6.18 billion, versus estimates of $5.84 billion. It posted $1.9 billion in licensing revenue, as investors continue to watch its growth in China and look for details on the company's agreement to acquire NXP Semiconductors.

Whole Foods Market saw its stock jump 4 percent in extended trading. The company reported earnings of 28 cents per share, 4 cents above analysts' expectations. Its revenues of $3.5 billion were in line with estimates.

The supermarket chain announced it would eliminate its co-CEO structure, naming co-founder John Mackey as the sole chief executive. Walter Robb will remain on the company's board of directors and will continue to serve as chairman for both Whole Kids Foundation and Whole Cities Foundation, effective Dec. 31, the company said.
