Baidu fell more than 2.5 percent in after-hours trade after reporting a miss on revenue and light guidance on second-quarter revenue. The Chinese search engine giant did beat earnings per share estimates.

Marriott declined sharply in extended-hours trade after reporting earnings that beat on revenue that missed.

However, gross margins were just shy of the full-year margin target.

Equinix jumped more than 5 percent in after-hours trade after the global data center and interconnection firm raised guidance on its 2015 annual revenue and earnings.

LifeLock spiked more than 4 percent in extended-hours trade after the identity theft protection firm reported record quarterly revenue and record gross new members. Revenue for the first quarter of 2015 was $134.4 million, an increase of 25 percent from the same period last year, the company said in a release.

DexCom, the producer of a glucose monitoring device for diabetics, fell more than 4 percent in extended-hours trade despite reporting unaudited results for the first quarter that reported a 55 percent increase in total revenue from the first quarter last year, as well as a similar increase in total gross profit.

Apple fell about half a percent in after-hours trade on a report the iPhone maker found defects in a "key component" of its new Apple Watch, Dow Jones reported, citing sources.
