(Oxford) (NYSE: OHP) announced today that they have signed a definitive agreement under which UnitedHealthcare, a wholly owned subsidiary, will merge with Oxford. Oxford serves and provides health care and benefit services for approximately 1.5 million people, principally in New York City, northern New Jersey and southern Connecticut. Completion of the acquisition, subject to regulatory approvals, approval by Oxford shareholders and other customary conditions, is expected during the fourth quarter of 2004. Under the terms of the agreement, Oxford shareholders will receive UnitedHealth Group stock at a fixed exchange ratio of 0.6357 shares for each Oxford share, plus $16.17 in cash per Oxford share. The total consideration for the transaction is a combination of approximately 54.7 million shares and $1.4 billion in cash, not including the effective benefit of Oxford's cash of approximately $200 million in excess of debt and capital requirements. This mix of equity and cash preserves the current balanced capital structure of UnitedHealth Group. UnitedHealth Group Chairman and CEO William W. McGuire, MD, commented that "this business combination provides the basis for significantly advancing the breadth and quality of health care services available to people in the tri-state region, and seeks to enhance our ability to work effectively and efficiently with key physicians and care providers within this large and diverse community. Those advances should produce greater access and affordability." McGuire added that "this merger with Oxford brings together their exceptionally focused local capabilities and UnitedHealth Group's national access, specialized centers of excellence Premium Networks, market-leading technologies and data sources, diverse specialized products and services, and unique offerings to seniors. The combined companies will have the scale and resources to more fully advance services on behalf of the broad client base within the tri-state area, as well as their related business affiliates across the country." "This merger will enhance our capabilities, strengthen our product offerings and build on the leadership of the Oxford brand in the tri-state region, said Charles Berg, president and CEO of Oxford. "The joining together of our two highly complementary organizations will provide important benefits to the people and communities we serve and allow us to leverage important new business opportunities. The combination will diversify our customer portfolio and enable us to better address the needs of consumers, our care providers and other key constituencies by offering enhanced flexibility, efficiencies and service. The key to Oxford's success has always been our exceptional people and relationships, and we are excited about expanding our ability to deliver quality and affordable health care in the tri-state area." Robert Sheehy, UnitedHealthcare CEO, stated, "Oxford's brand and reputation will significantly expand our presence in the northeastern markets. We will retain the Oxford brand and operations, and the combined tri-state business will continue under the leadership of Chuck Berg. We have immense respect for Oxford management and employees, the company they have become, and the quality of services they provide to this important marketplace. All of us look toward a future built around growth through superior products, high quality services and greater affordability." Tracy Bahl, CEO of Uniprise, UnitedHealth Group's business dedicated to serving large, multisite employers, added that "we look forward to bringing the unique health system access that Oxford offers to the 43 large, multisite, employers based in the tri-state area that we currently serve, as well as the opportunity to present our joint capabilities to the nearly 50 Fortune 500 employers headquartered in the region and with whom we have no current relationship. In addition, we are excited about presenting our combined resources and capabilities to the many large employers that are headquartered elsewhere and have significant employment bases in the tri-state area." UnitedHealth Group anticipates the acquisition will be immediately accretive to earnings per share upon closing, adding earnings at an annual rate of $0.16 per share, excluding first year operational synergies of at least $80 million to $100 million. The earnings from accretion and operational synergy will be additive to the UnitedHealth Group current expectation of 15 percent or greater growth in earnings per share in 2005 and will be included in the Company's forward financial projections after the transaction is closed.
