UnitedHealthcare of Wyoming Inc history

In January 1977 the company was incorporated as United HealthCare Corporation.

In June 1985 United HealthCare made its first major acquisition since going public, acquiring Share Development Corporation, an Indiana-based multi-state HMO through a stock swap valued at nearly $60 million.

That month, on the heels of the HMO America deal, United HealthCare agreed to make its first divestiture since 1987, selling its Des Moines-based health plan with about 26,000 members.

In another restructuring move designed to shore up its relationship with PHP, United agreed to a new five-year contract in April 1988, which gave the PHP board of directors the power to appoint its own chief executive and other key officers.

Nevertheless, the restructuring program eventually returned United to profitability, and by the end of 1989 it was one of the largest publicly traded HMOs in the United States, serving about one million people in 15 states.

In July 1990 United became the first managed health care company to go after clients already associated with other HMOs, offering three types of health care services separately rather than in a package.

In July 1991 United purchased the Wauwatosa, Wisconsin-based Samaritan Health Plan Insurance Corporation, one of the first hospital-sponsored HMOs in the country.
