FOR IMMEDIATE RELEASE

 

INTERPUBLIC SCHEDULES FULL YEAR 2005 EARNINGS RELEASE

New York, NY (March 9, 2006) – Interpublic Group (NYSE: IPG) today announced that it will release earnings for the full year 2005 and file its annual report on form 10-K on the morning of March 22, 2006. The company will hold a conference call for investors at 8:30 a.m. Eastern Time on that date to review results.

The company intends to avail itself of a portion of the 15-day grace period afforded by SEC Rule 12b-25. The company indicated that, given its previously disclosed material weaknesses, the extension is necessary to complete the procedures required to finalize the accounting for previously disclosed issues primarily related to client and vendor credits.

Management expects that it will receive an unqualified opinion on the company’s 2005 financial results from its outside auditors and, consistent with previous disclosure, an adverse opinion on the operating effectiveness of its internal controls over financial reporting. The company also reiterated that it will hold its Investor Day meeting on March 27, 2006 in New York.

To join the conference call on March 22, please call (866) 314-5050. Outside the United States, please call (617) 213-8051. The participant passcode is 77796093. The call can be accessed live on the company’s website, www.interpublic.com.

The conference call will be recorded and available for 30 days by calling (888) 286-8010 followed by the passcode 95089674. Outside the United States, please call (617) 801-6888 followed by the passcode 95089674. The call will also be archived and available in the investor relations section of the company’s website.
