Wisconsin Firm to Buy HMO California

HMO California said Wednesday that it has agreed to be acquired by Employers Health Insurance Co., a unit of Emphesys Financial Group Inc. of Green Bay, Wis. Terms of the purchase by Employers Health, the nation’s 10th-largest group health insurance company, were not disclosed.

HMO California, a privately held company based in Newport Beach, has customers in Orange, Los Angeles, Riverside and San Bernardino counties.

The transaction calls for the five medical groups that previously owned HMO California to continue as health care providers for the new owner.
