Current Filing Status With SEC is Critical Step Forward for the Company

Company Expects to Resume Share Repurchase Program

MINNEAPOLIS -- UnitedHealth Group Incorporated (NYSE:UNH) announced today that the Company expects to file its Form 10-K for 2006 with the Securities and Exchange Commission (SEC) on or before March 15, 2007, along with an amended Form 10-Q filing for the first quarter 2006 and Form 10-Q filings for the second and third quarters of 2006. The Company did not complete these quarterly reports previously due solely to stock option accounting matters. Today the Company filed Form 12b-25 requesting an automatic two-week extension beyond the March 1 deadline for filing its Form 10-K.

When its Form 10-K for 2006 has been filed and the Company is once again current with its SEC periodic reports, UnitedHealth Group expects to resume its share repurchase program.

Stephen J. Hemsley, president and chief executive officer of UnitedHealth Group, said, "Resuming timely and complete periodic reports is critical to the interest of our investors, customers and employees, and we are very pleased that we have been able to move quickly and judiciously in cooperation with the SEC. We look forward to completing these reports, continuing our efforts to improve corporate governance, and focusing intently on executing our business strategy for the benefit of our customers."
