Take a look at some of the companies making headlines after the close:
Netflix surged 12 percent to a new high in after-hours trade after reporting strong growth in subscribers. However, the streaming service posted earnings that missed expectations on revenue that was in line with estimates.
SanDisk fell more than 2.5 percent in extended-hours trade after posting the first decline in quarterly revenue in two years. Lower prices and weaker-than-expected sales of data center storage products hurt the memory chipmaker.
Kinder Morgan fell nearly 1 percent in extended-hours trade after the energy infrastructure company reported a decline in first-quarter revenue to $3.5 billion from $4 billion during the same period last year. However, the firm announced a 14 percent increase in its quarterly dividend from the year-ago period.
Amgen gained more than 1 percent in after-hours trade following news the U.S. Federal and Drug Administration approved the firm's first cardiovascular drug, Corlanor, which treats patients with chronic heart failure.
