BELLEVUE, Wash. ( TheStreet) -- DVD specialist Coinstar ( CSTR) posted robust first-quarter results after market close on Thursday, boosted by the company's Redbox rental business. Coinstar, which released preliminary numbers earlier this month, brought in revenue of $568.2 million, a 34% hike on the prior year's quarter, and comfortably above analysts' forecast of $563.49 million. The company's Redbox revenue climbed 38.8% year-over-year to $502.9 million, driven by growth in same-location sales, new kiosk installations, and the strong performance of new release titles. In a statement, Coinstar also noted consumer acceptance of a price increase implemented on Oct. 31, 2011. Excluding items, Coinstar earned $1.39 a share, up from 46 cents a share in the prior year's quarter. Analysts surveyed by Thomson Reuters were looking for earnings of $1.34 a share. "Coinstar delivered strong financial results in the first quarter demonstrating the strength of our core businesses and the value we offer consumers," said Paul Davis, the Coinstar CEO, in the statement. "As we move forward in 2012, we continue to execute on a number of important initiatives including the launch of our Redbox digital solution with Verizon ( VZ) via our joint venture and the rollout of one to two of our new venture businesses." The Bellevue, Wash.-based firm expects second-quarter revenue between $525 million and $550 million and earnings between $1.09 and $1.24 a share. Analysts are looking for sales of $544.14 million and earnings of $1.05 a share. For the full year, Coinstar reiterated its earlier forecast of revenue between $2.155 billion and $2.28 billion and earnings between $4.40 and $4.80 a share, at the low end of analysts' forecasts.
