Electronic Arts’ Harry Potter sales are helping boost the bottom line. However, the company reported a slight drop in revenue for its first quarter, which ended June 30. The Redwood City, California-based video game publisher generated US$395 million in net revenue, down 4% from ’06 numbers.

Harry Potter and the Order of the Phoenix, Command & Conquer 3 Tiberium Wars, The Sims 2 Pets, Need for Speed Carbon and The Sims 2 were the company’s highest-selling games in Q1.

Gross profit rang in at US$229 million, down 7%, while EA marked a net of US$132 million, up significantly from last year’s US$81 million total.

CEO John Riccitiello says that in the wake of the company’s reorganization into four divisions, he is pleased with the Q1 results and looks forward to launching a full slate of EA properties including the as-yet-unnamed Steven Spielberg title and The Simpsons video game.

Additionally, EA recently expanded into Asia with a 15% equity investment in Chinese online game operator The9 Limited, which has inked an agreement to bring EA Sports FIFA online to China.
