Tesla Motors - The electric automaker's adjusted first-quarter loss was narrower-than-expected as revenue rose more than 50 percent from a year ago. However, the company warned that the stronger dollar would negatively impact margins in the coming quarter. Shares rose more than 2 percent after the announcement.

21st Century Fox - The media and entertainment firm's shares rose about 1 percent after it topped earnings projections, although sales figures trailed estimates.

Whole Foods - Shares plunged 10 percent after the natural and organic foods retailer missed revenue forecasts, while comparable-store sales rose 3.6 percent, well under the 5.3 percent Wall Street had expected. The company reported fiscal second-quarter earnings of 43 cents a share, in line with estimates, on $3.65 billion in revenue. Analysts had forecast sales of $3.71 billion.

Zynga - The gaming developer said it would reduce its workforce by about 18 percent as a part of its new restructuring plan. The company also topped first-quarter estimates on the top and bottom lines, sending shares up about 7 percent in after-hours trading.

Keurig Green Mountain - The maker of K-Cup single-serve coffee pods reported adjusted earnings of $1.03 a share on $1.13 billion in revenue, missing expectations of $1.05 a share on $1.15 billion in revenue. Shares tumbled about 12 percent in extended trading.

Ann Inc - The women's retailer is reportedly in advanced talks to possibly be acquired by Golden Gate Capital, according to Reuters. Ann shares jumped as much as 15 percent after the news.
