UnitedHealth Group Highlights

UnitedHealth Group reported growth in earnings from operations for all reporting segments in 2007. Fourth quarter results included growth in earnings from operations for Prescription Solutions, OptumHealth and Ingenix, while Health Care Services fourth quarter earnings from operations decreased modestly, as expected.

• Consolidated revenues for full year 2007 increased $3.9 billion or 5 percent to $75.4 billion. Revenues for every reporting segment increased in 2007, with particularly notable growth in Prescription Solutions, Ingenix and AmeriChoice in Health Care Services. Fourth quarter revenues of $18.7 billion increased $577 million or 3 percent year-over-year and were stable sequentially.

• Full year adjusted earnings from operations of $8.0 billion advanced 15 percent over 2006 results. Each reporting segment increased its operating earnings by a double-digit percentage in 2007, led by Prescription Solutions, up 94 percent, and Ingenix, up 51 percent. Earnings from operations increased to $2.0 billion in the fourth quarter, up $57 million or 3 percent over the prior year, and down $117 million or 5 percent sequentially. This decline was entirely due to the seasonal decrease in Health Care Services fourth quarter results.

• Full year adjusted net earnings advanced to $4.766 billion¹, up $607 million or 15 percent over 2006 results. Fourth quarter consolidated net earnings increased to $1.216 billion, up $41 million or 3 percent year-over-year, and decreased $67 million or 5 percent on a sequential quarter basis, as expected.

• The full year adjusted operating margin of 10.6 percent improved 80 basis points from 9.8 percent in 2006, driven by gains in both the medical care ratio and operating cost ratio. The consolidated fourth quarter operating margin of 10.9 percent was stable with the fourth quarter of 2006.

• Full year adjusted earnings of $3.50 per share¹ increased 18 percent from $2.97 per share in 2006 driven by 15 percent growth in adjusted earnings from operations and a 3 percent reduction in diluted weighted average shares outstanding. Fourth quarter earnings per share of $0.92 increased 10 percent from $0.84 in the fourth quarter of 2006, and decreased 3 cents or 3 percent from the third quarter of 2007, as expected.

Highlights for UnitedHealth Group – Continued

• Cash flows from operations were 126 percent of net earnings or $5.88 billion for the year, including $1.07 billion for the fourth quarter. The timing of state Medicaid program receivables collections, income tax payments and federal program payments affected fourth quarter cash flows.

• The 2007 consolidated medical care ratio of 80.6 percent decreased 60 basis points from 81.2 percent in 2006 due largely to improvements in public and senior markets businesses. The fourth quarter medical care ratio of 79.9 percent was stable compared with 80.0 percent in the fourth quarter of 2006.

• Full year favorable development of prior year medical cost estimates of $420 million in 2007 compares to $430 million in 2006 and $400 million in 2005. During the fourth quarter, the Company realized favorable development of $70 million in its estimates of medical costs incurred in 2006. The Company also realized $10 million in favorable development in the fourth quarter related to estimates of medical costs incurred in the first nine months of 2007, with no effect on full year results.

• Consolidated medical costs days payable were 57 days for the fourth quarter of 2007, as compared to 56 days for the fourth quarter of 2006. Excluding the AARP division of Ovations, medical costs days payable were 54 days for the fourth quarter of 2007 and 53 days for the fourth quarter of 2006.

• The full year adjusted operating cost ratio of 13.8 percent¹ improved 20 basis points from 14.0 percent in 2006 reflecting effective operating cost management. Operating costs represented 14.4 percent of revenues in the fourth quarter, including about 30 basis points of incremental advertising and related market launch expenses for the AARP-branded Medicare Advantage offerings. Excluding these expenses, the fourth quarter 2007 operating cost ratio was stable with fourth quarter 2006.

• The income tax rate of 36.3 percent was consistent for full year 2007 and 2006. The fourth quarter 2007 income tax rate of 35.5 percent decreased 80 basis points sequentially primarily due to the mix of profitability among state tax jurisdictions.

• UnitedHealth Group repurchased 125 million shares in 2007 for $6.6 billion, including 40 million shares in the fourth quarter for $2.2 billion.

• Full year 2007 return on equity exceeded 22 percent, with fourth quarter 2007 annualized return on equity at 24 percent. Strong returns on equity were driven by double digit operating margins and an increasingly efficient capital structure.

As previously disclosed, during the fourth quarter of 2007 the Company completed the realignment of its business segment financial reporting. The most prominent changes to segment reporting include disclosure of the results of operations of the pharmacy benefit management business – Prescription Solutions – as a free-standing segment, and the inclusion of the large group, multi-site health benefits company – Uniprise – as part of the Health Care Services reporting segment. The fourth quarter and full year 2007 information reflects this new reporting structure. Historical financial data also reflect the new segment presentation to enhance comparability between periods.

Outlook

UnitedHealth Group continues to project earnings of approximately $3.95 to $4.00 per share for full year 2008, an increase of approximately 13 percent to 14 percent over adjusted 2007 results, and cash flows from operations are expected to approach $7 billion. First quarter 2008 earnings are expected to be in the range of $0.82 to $0.84 per share.

Key Developments for Health Care Services

The fourth quarter for the Health Care Services segment included important product launch activities for UnitedHealthcare, improving AmeriChoice financial performance, intensive marketing of Ovations Medicare Advantage offerings for January 2008, and sequential growth in fee-based employer-sponsored product lines offset by a decrease in consumers served under risk-based arrangements.

• Full year Health Care Services revenues increased $3.4 billion or 5 percent to $71.2 billion, led by the $1.8 billion advance in Ovations revenues. Revenues grew $442 million or 3 percent year-over-year and decreased $31 million sequentially to $17.6 billion in the fourth quarter of 2007. The decrease was primarily due to the timing of Part D revenue recognition and routine product and membership reconciliations with the Centers for Medicare and Medicaid Services, offset by business growth at AmeriChoice.

Page 4 of 11

Key Developments for Health Care Services – Continued

• Full year Health Care Services earnings from operations grew $735 million or 13 percent over 2006 results due largely to the strong performance of public and senior markets businesses. Fourth quarter Health Care Services earnings from operations of $1.6 billion decreased $50 million or 3 percent year-over-year and $187 million or 10 percent from third quarter of 2007. These decreases reflect a seasonally higher fourth quarter medical care ratio at UnitedHealthcare and increased market launch, advertising and enrollment costs for Ovations.

• Health Care Services full year operating margin of 9.3 percent expanded 70 basis points year-over-year and decreased 50 basis points year-over-year and 110 basis points sequentially to 9.1 percent in the fourth quarter of 2007.

• Full year Ovations revenues of $26.5 billion increased more than $1.8 billion or 7 percent over 2006 results, with revenue advances in its AARP Medicare supplement, SecureHorizons Medicare Advantage, Evercare chronic and elderly, and Part D businesses. Ovations reported revenues of $6.3 billion in the fourth quarter, up $109 million or 2 percent year-over-year. Revenues decreased $87 million or 1 percent from the third quarter of 2007 due to the timing of Part D revenue recognition and routine product and membership reconciliations with the Centers for Medicare and Medicaid Services

• Ovations saw strong membership growth in its active Medicare supplement products in 2007, with its membership growing by 125,000 seniors or 5 percent for the full year, including 30,000 seniors or 1 percent growth in the fourth quarter. Participation in Medicare Advantage offerings was stable in the fourth quarter and decreased by 75,000 people or 5 percent in 2007, principally in Private Fee-for-Service products.

• On October 1, 2007, Ovations launched nationwide marketing for its Medicare products for 2008. New developments include a significant expansion of chronic care Special Needs Plan offerings from seven states to 34 states; new Part D drug benefits, including zero copay generic prescriptions filled by mail order; and targeted geographic expansions for Medicare Advantage programs. Importantly, Ovations network-based SecureHorizons Medicare Advantage programs are now exclusively offered on a co-branded basis with AARP for the first time. Ovations estimates it will add 125,000 to 175,000 seniors in its Medicare Advantage product lines in 2008.

• Full year AmeriChoice revenues of $4.5 billion increased $750 million or 20 percent year-over-year, driven by strong organic growth in people served and moderate increases in premium yields on a same-state basis. AmeriChoice fourth quarter revenues of $1.2 billion increased $227 million or 24 percent year-over-year and $35 million or 3 percent from the third quarter of 2007.

• AmeriChoice expanded its services to an additional 245,000 people in 2007, representing a 17 percent increase year-over-year, including 10,000 people in the fourth quarter. Growth highlights include the successful initiation of services to residents of central Tennessee covered by the TennCare program, expansion in Texas, and new services in Indiana that became available on January 1, 2008.

Key Developments for Health Care Services – Continued

• UnitedHealthcare and Uniprise combined full year revenues of $40.3 billion increased by $821 million or 2 percent year-over-year as yield increases more than offset a modest reduction in people served. Fourth quarter revenues increased $106 million or 1 percent year-over-year and grew $21 million sequentially.

• UnitedHealthcare and Uniprise had a combined decrease of 175,000 people served, or about 0.7 percent, across all products in 2007, including more than 300,000 people related to the continued repositioning of the PacifiCare acquisition, which will continue through the first half of 2008. The full year results include a decrease of 50,000 people in the fourth quarter, as growth of 25,000 consumers in fee-based products was offset by a reduction in risk-based membership of 75,000 people.

• In 2007 Uniprise and UnitedHealthcare advanced their leadership position in the consumer-directed health benefit product market. These businesses served a total of 2.3 million people through their consumer-directed offerings at December 31, 2007, representing organic growth of 425,000 consumers or 22 percent year-over-year. More than 9 percent of commercial membership is in one of these plans, with penetration reaching 12 percent for both Uniprise large group and UnitedHealthcare small business customers. This strong growth has been spurred by UnitedHealth Group’s investment in tools and resources that engage and support consumers in information gathering and decision-making, as well as the ability to offer seamless linkages to health financial services through OptumHealth.

• The full year UnitedHealthcare medical care ratio of 82.1 percent increased 230 basis points in 2007. As previously disclosed, this ratio reflects an unfavorable variance in reserve development between years and a shortfall in realized premium yield. The Company anticipates this medical care ratio will be stable in 2008.

• UnitedHealthcare’s fourth quarter 2007 medical care ratio of 83.7 percent compares to a ratio of 81.6 percent in the third quarter of 2007. The sequential increase reflects higher seasonal utilization of health care services in the fourth quarter, as anticipated, as well as an accrual that reduced premium revenues in the quarter, due to one state’s recently issued regulatory determinations on prior year underwriting performance.

Key Developments for OptumHealth

During 2007, UnitedHealth Group rebranded its specialty businesses as OptumHealth, reinforcing their personalized, caring and lifelong relationships with consumers. The unified OptumHealth image better reflects its comprehensive and integrated capabilities.

• OptumHealth expanded its market share in 2007 by both providing services to 2.1 million more people and by increasing product and service penetration within its established customer base. Full year OptumHealth revenues of $4.9 billion increased $579 million or 13 percent, while fourth quarter revenues rose to $1.3 billion, up $145 million or 13 percent year-over-year, and $16 million or 1 percent over third quarter 2007.

• Full year earnings from operations at OptumHealth grew $86 million or 11 percent year-over-year to $895 million. In the fourth quarter, earnings from operations of $239 million increased $24 million or 11 percent year-over-year and improved $15 million or 7 percent from third quarter 2007.

• The OptumHealth operating margin of 18.2 percent in 2007 compares to 18.6 percent in 2006. The year-over-year margin change reflects strong growth from public sector clients that are contributing relatively larger per client revenues at comparatively lower overall margins. OptumHealth’s fourth quarter operating margin of 19.0 percent decreased 40 basis points year-over-year but increased 90 basis points sequentially. The sequential gain in operating margin was principally due to effective operating cost management.

• Optum Financial Services (Exante) reached $460 million in assets under management and served more than 1.3 million financial accounts at December 31, 2007. Optum Financial Services (Exante) moved $19 billion in payments electronically to health system providers during 2007, representing 80 percent growth in electronic payments year-over-year.

Operating Margin		29.0	%		19.2	%		24.6	%		20.4	%		18.4	%

Key Developments for Ingenix

Ingenix continues to build momentum, with strong growth in virtually every performance metric. This business is responding to the growing needs for data-driven solutions, analytics and consulting services by all participants across the health care system. Fourth quarter results show particularly notable strength due to the seasonal sales activity that occurs annually in the fourth quarter in certain Ingenix product lines.

• On a full year basis, Ingenix grew revenues by $348 million or 36 percent over 2006 results, with strong revenue growth across every major product line. In the fourth quarter of 2007, Ingenix revenues increased $113 million or 38 percent year-over-year and $70 million or 20 percent sequentially, to $414 million.

• The Ingenix revenue backlog of $1.7 billion at December 31, 2007 increased 46 percent year-over-year, positioning Ingenix for continued growth performance in 2008.

• Market demand for newer Ingenix offerings continues to expand. For example, data interchange volume tripled year-over-year in the fourth quarter of 2007, and Ingenix nearly doubled its in-house consulting capacity to more than 1,000 professionals over the course of the year.

• Ingenix full year earnings from operations increased $90 million or 51 percent, with fourth quarter earnings from operations of $120 million, up $46 million or 62 percent year-over-year and $54 million or 82 percent from third quarter 2007. The full year 2007 operating margin of 20.4 percent improved 200 basis points over 2006. The fourth quarter 2007 operating margin of 29.0 percent increased 440 basis points year-over-year and 980 basis points on a sequential basis, due to seasonal demand for certain higher-margin Ingenix offerings.

Key Developments for Prescription Solutions

During 2007 Prescription Solutions was established as a free-standing reporting segment of UnitedHealth Group and continued to strengthen its capabilities as it positioned for growth.

• On January 1, 2007, Prescription Solutions began providing prescription drug benefit services to approximately 4 million additional seniors on behalf of Ovations. Driven by this growth, Prescription Solutions revenues increased $9.2 billion or 224 percent for full year 2007 and $2.3 billion or 215 percent for fourth quarter 2007, reaching $13.2 billion and $3.3 billion for the respective periods. Because of the relationship between Ovations and Prescription Solutions, approximately $9 billion of the full year revenue growth is eliminated in the intercompany elimination process.

• Full year earnings from operations grew $130 million or 94 percent to $269 million, with fourth quarter earnings from operations of $78 million increasing $37 million or 90 percent over comparable 2006 results. The Prescription Solutions full year operating margin of 2.0 percent declined 140 basis points year-over-year, reflecting the comparatively lower margin earned in the high volume Ovations Part D prescription drug service contract and, to a lesser extent, costs associated with positioning the business for continued strong growth. For similar reasons, the fourth quarter operating margin of 2.4 percent decreased 150 basis points year-over-year and was stable sequentially.

(a) Certain account balances and financial measures have been presented in this earnings release excluding our AARP business. Management believes these disclosures are meaningful since underwriting gains or losses related to the AARP business are recorded as an increase or decrease to a rate stabilization fund (RSF) and the effects of changes in balance sheet amounts associated with the AARP program accrue to the overall benefit of the AARP policyholders through the RSF balance. Although the Company is at risk for underwriting losses to the extent cumulative net losses exceed the balance in the RSF, the Company has not been required to fund any underwriting deficits to date and management believes the RSF balance is sufficient to cover potential future underwriting or other risks associated with the contract.
