Videogame developer THQ Inc. saw its profit and a sales jump on solid sales of its “Saints Row” videogame.

The Agoura Hills-based company reported second-quarter net income of $12.6 million (19 cents per share), an improvement from a loss of $1.4 million (-2 cents) for the same period a year earlier. Sales were up 40 percent to $240 million. However, THQ said the results are likely to change because of an investigation into the company’s stock option grants.

The results topped the Wall Street estimates of 3 cents a share on $201 million in sales. They were boosted mainly by strong sales of new games, specifically “Saints Row” which shipped more than 1 million copies in the quarter as well as older titles such as “Cars,” which performed well in Europe, the company said.

Shares in THQ were up 2 cents to $30.12 in early trading Friday.
