ST. PETERSBURG, Fla., (April 4, 2006) – Catalina Marketing Corporation (NYSE: POS) today announced that it received notification from the U.S. Securities and Exchange Commission (SEC) that it has completed its investigation of Catalina Marketing.

Throughout the investigation, Catalina cooperated fully with the SEC. The SEC staff notified Catalina that they do not intend to recommend enforcement action against the company.

“The notification from the SEC was an important development for Catalina Marketing,” said Dick Buell, chief executive officer. “Since the SEC began its investigation, we have been committed to helping to resolve any and all issues in a timely fashion.
