Coinstar, owner of the Redbox movie-rental kiosks, said second-quarter profit rose 38 percent after the company added new locations and customers.

The shares fell nearly 13 percent after hours as revenue growth missed estimates.

Net income rose to $36.9 million, or $1.11 a share, from $26.7 million, or 83 cents, a year earlier, the Bellevue, Washington-based Coinstar said yesterday.

Excluding items, its profit of $1.25 exceeded the $1.16 a share that was expected.
