NEW YORK (TheStreet) -- Shares of Glu Mobile (GLUU - Get Report) were gaining 14.1% to $4.38 after-hours Wednesday after the mobile game publisher announced a new game with Katy Perry and beat analysts' estimates for the fourth quarter.

Glu will release a free-to-play game for iOS and Android using the voice, likeness, and personality of Katy Perry worldwide in late 2015, the company announced.

Katy Perry "is a cultural icon and we expect to translate key elements of her success into an innovative, highly entertaining mobile experience," Glu CEO Niccolo de Masi said. "We anticipate that Katy`s significant global audience, including more than 170 million* fans on social media, will make her a strong gaming partner for Glu."

TheStreet Ratings team rates GLU MOBILE INC as a Hold with a ratings score of C. TheStreet Ratings Team has this to say about their recommendation:

"We rate GLU MOBILE INC (GLUU) a HOLD. The primary factors that have impacted our rating are mixed -- some indicating strength, some showing weaknesses, with little evidence to justify the expectation of either a positive or negative performance for this stock relative to most other stocks. The company's strengths can be seen in multiple areas, such as its robust revenue growth, largely solid financial position with reasonable debt levels by most measures and impressive record of earnings per share growth. However, as a counter to these strengths, we find that the stock has had a generally disappointing performance in the past year."
