It’s earnings season for some of the key firms in the mobile gaming world, with three more companies declaring their Q3 financials yesterday: DeNA, Gameloft and Com2uS.

DeNA is the 900lb gorilla of the trio, having generated revenues of $627m in Q3, up 45% year-on-year. The Japanese company posted operating income of $254m, up 38%.

The bulk of those revenues are still coming from Japan, but the company’s global expansion is proceeding apace, with more than 80 games now available in the West using its Mobage platform.

French-headquartered publisher Gameloft reported its Q3 results too, posting revenues of $70.8m – its profit figures will follow later, as usual.

The company said its smartphone and tablet sales grew 124% year-on-year, and now account for 56% of its revenues – with three fifths of those smartphone and tablet revenues coming from IAP and ads. Gameloft added that it now has 56m monthly active users across its games.

Finally, Korean publisher Com2uS reported $20.5m of revenues for Q3 and net income of $6.8m, with smartphones accounting for 94% of its total revenues compared to 74% a year ago.
