THQ Inc. said Wednesday that it has received a delisting notice from the Nasdaq Stock Market for failure to file its most recent quarterly financial reports.

The Agoura hills-based videogame developer said it has requested a hearing and attributed the delay in filing to an ongoing investigation into past stock option grants.

THQ was notified by the Securities and Exchange Commission on Aug 7 that a formal investigation would be conducted into stock options grants made by the company from 1996 until now.

Shares of THQ will remain on the Nasdaq while a hearing is conducted.

THQ is among at least 180 companies whose past option grants have come under internal or U.S. regulatory review, and one of several companies in the L.A. area, including the Cheesecake Factory, Activision Inc., Hansen Natural Corp. and KB Home.

Shares in THQ were up 19 cents to $31.29 in trading Wednesday.
