Take a look at some of Thursday's after-hours buzz:
Restoration Hardware fell more than 3.5 percent in extended-hours trade after the firm gave weak guidance, citing the negative impact of the West Coast port shutdown. The upscale home goods brand reported fourth-quarter earnings that were mostly in line with estimates.
GameStop fell more than 4 percent in after-hours trade after reporting fourth-quarter earnings that showed a 5.6 percent drop in quarterly revenue, hurt by lower hardware demand during the holiday shopping season. The world's largest retailer of video game products also reported a decline in total global sales and a 1.8 percent decrease in comparable-store sales.
Google edged higher in extended-hours trade after the tech giant announced that Ruth Porat will have a base pay of $650,000, a $5 million signing bonus and a large amount of restricted stock. Currently an executive at Morgan Stanley, Porat will officially join Google as its chief financial officer and executive vice president on May 26, 2015.
Carnival gained more than 1 percent in after-hours trade when the cruise company announced in a press release that it signed two partnerships with European shipbuilders to add nine new cruise ships over a four-year period starting in 2019.
