McGuire, M.D. “Our services now extend to 70 million people, as we have significantly expanded our share in high-growth health care markets such as senior health care, consumer-driven health products, and technology and data services, as well as deepened our position in employer benefit services in key geographic markets,” stated Dr. McGuire. “Our operating momentum now supports earnings per share growth in the range of 23 percent to 25 percent in 2006, a further advance over our outlook of three months ago.”

UnitedHealth Group Highlights

UnitedHealth Group first and second quarter 2006 revenues, earnings from operations and operating margins were significantly affected by the acquisition of PacifiCare Health Systems (PacifiCare) and the commencement of Medicare Part D. In the UnitedHealth Group and segment highlights, only sequential quarterly comparisons and commentary are provided for certain metrics, as year-over-year performance comparability is affected by the business mix changes driven by those two important developments.

• Second quarter earnings per share of $0.70 increased 21 percent from $0.58 in the second quarter of 2005, and improved 7 cents or 11 percent from the first quarter of 2006.

• Second quarter consolidated net earnings increased to $974 million, up $204 million or 26 percent year-over-year and $75 million or 8 percent from the first quarter of 2006.

• Consolidated revenues of $17.9 billion increased $6.5 billion or 57 percent year-over-year, and $331 million or 2 percent from the first quarter of 2006.

• Consolidated earnings from operations increased to $1.6 billion in the second quarter, up $389 million or 31 percent over the prior year, and up $152 million or 10 percent sequentially.

• The Company expanded its reach to nearly 4 million entirely new individuals through the first six months of 2006, with strong growth achieved across employer health benefits programs, senior and government services offerings and specialty product lines.

• Consolidated second quarter operating margin improved to 9.1 percent from 8.4 percent in the first quarter of 2006, reflecting diversified growth coupled with effective continuing expense management and improved underlying business performance in multiple businesses.

UnitedHealth Group Highlights – Continued

• Second quarter operating costs of $2.6 billion increased by only $6 million from their level in first quarter 2006. Operating costs declined to 14.4 percent of revenues in the second quarter, an improvement of 70 basis points from the second quarter of 2005 and 20 basis points from the first quarter of 2006.

• The consolidated medical care ratio (medical costs as a percentage of premium revenues), which includes all businesses and products, declined 50 basis points on a sequential quarter basis to 82.0 percent. As expected, on a year-over-year basis the consolidated medical care ratio increased due to the impact of the acquisition of PacifiCare and the commencement of Medicare Part D.

• Consolidated medical costs payable, excluding the AARP division of Ovations, increased to $7.2 billion at June 30, 2006. Medical costs days payable, which includes all recent acquisitions and the Part D business, remained at 53 days for the quarter, comparable to its level of 53 days payable at March 31, 2006.

• During the second quarter, the Company realized favorable development of $150 million in its previous estimates of medical costs incurred, virtually all of which pertained to prior years.

• Accounts receivable, excluding the AARP division of Ovations, were $929 million at June 30, 2006, and represented 5 days sales outstanding.

• Reported cash flows from operations were $1.7 billion for the second quarter, bringing year-to-date operating cash flows to $4.6 billion. Adjusted to align CMS payment timing to the proper periods, second quarter cash flows from operations were $1.54 billion, up 24 percent year-over-year, and adjusted year-to-date cash flows were $3.1 billion.

• The Company repurchased 10 million shares during the second quarter of 2006, bringing the year-to-date total share repurchase to 40 million shares, or 3 percent of the shares outstanding at December 31, 2005.

• Second quarter 2006 annualized return on equity was 22 percent, up from 20 percent in first quarter 2006.

• The Company supplemented its GAAP results by reporting Part D normalized results for the second quarter of 2006 as follows: earnings per share of $0.73, revenues of $17.841 billion, medical costs of $13.392 billion, a consolidated medical care ratio of 81.5 percent, an operating cost ratio of 14.4 percent, earnings from operations of $1.705 billion, and net earnings of $1.017 billion. Because Part D benefit costs for the new Medicare Part D program are disproportionately higher in the first half of the contract year due to the benefit design, Part D normalized results assume that full-year Medicare Part D benefit costs are recognized based on actuarially projected utilization over the contract year. These amounts represent non-GAAP financial measures and have been presented to facilitate comparability with 2005 quarterly financial results. A further explanation of this basis of presentation and a reconciliation of such amounts to the comparable GAAP measures is included in the attached financial schedules.

Closing Comment

“We have a positive outlook for further earnings growth this year. Our businesses are in an excellent position to sustain growth and performance, driven by the overall value that their services, technologies and products offer to customers in the end-markets they serve,” concluded Dr. McGuire. “Our quarterly results should benefit substantively in the second half of 2006 from the natural seasonality embedded in a number of our businesses, including Medicare Part D. We therefore expect to see accelerating earnings per share growth in the second half of this year. At the same time, we continue to build a foundation for future growth in 2007 and beyond, and expect baseline earnings per share to climb another 15 percent in 2007 above our increased 2006 outlook of $2.91 to $2.95 per share.”

Key Developments for Health Care Services

Health Care Services revenues, earnings from operations and operating margins were significantly affected on a year-over-year basis by the acquisition of PacifiCare and the commencement of Medicare Part D.

• Revenues for Health Care Services grew $6.2 billion or 63 percent year-over-year and $302 million or 2 percent sequentially to $16.0 billion in the second quarter of 2006.

• Second quarter Health Care Services earnings from operations of $1.2 billion increased $291 million or 32 percent year-over-year and $147 million or 14 percent sequentially.

• The second quarter operating margin of 7.5 percent expanded 80 basis points sequentially due to an overall improvement in segment profitability and a significant reduction in the quarterly loss incurred on a GAAP basis in the Medicare Part D business.

Key Developments for Health Care Services – Continued

• UnitedHealthcare second quarter revenues of $8.8 billion increased $2.1 billion or 31 percent year-over-year and $111 million or 1 percent sequentially.

• The number of consumers served by UnitedHealthcare at June 30, 2006 was in line with the first quarter, with a gain in fee-based subscribers of 20,000 people offset by a net 45,000-person reduction in risk-based members, including the divestiture of business in Arizona pursuant to the conditions of the PacifiCare merger. This brought the UnitedHealthcare year-to-date net sales gain to 225,000 people. Combining UnitedHealthcare with Uniprise, UnitedHealth Group achieved strong enterprise-wide organic growth of 715,000 consumers in employer-sponsored health benefits through the first six months of 2006.

• The second quarter 2006 medical care ratio for UnitedHealthcare was 79.9 percent, which was essentially stable with a ratio of 79.7 percent in the first quarter of 2006 for UnitedHealthcare. Excluding acquired commercial businesses, UnitedHealthcare had a medical care ratio of 78.9 percent in the second quarter of 2006, which was consistent with the first quarter 2006 ratio of 78.9 percent and up 30 basis points year-over-year from 78.6 percent in the second quarter of 2005. The 30 basis point increase reflected the fact that second quarter 2005 results for UnitedHealthcare included a comparatively higher level of favorable prior period development.

• Ovations reported revenues of $6.4 billion in the second quarter, up $4.1 billion or 180 percent year-over-year and $168 million or 3 percent from the first quarter of 2006. Ovations revenues grew 95 percent year-over-year on an organic basis, including the launch of Part D and growth in the PacifiCare senior businesses subsequent to closing.

• Ovations saw a strong increase in senior participation in medical products through the first six months of 2006, with gains in Medicare supplement product membership of 30,000 people in the second quarter and 85,000 people year-to-date. Similarly, Secure Horizons programs added 100,000 more seniors in the second quarter, bringing total year-to-date organic growth to 215,000 people in this set of offerings.

• The Ovations Part D business served a total of 5.7 million seniors as of June 30, 2006, and generated revenue of $1.5 billion and a reduced loss from operations in the second quarter as compared to first quarter 2006. The Part D business is well on track to provide positive contributions to earnings on a GAAP basis in the third and fourth quarters and meet its 2006 full-year operating margin target of 3 percent to 4 percent.

• AmeriChoice second quarter revenues of $913 million increased $69 million or 8 percent year-over-year and $23 million or 3 percent from the first quarter of 2006.

• AmeriChoice membership increased by a total of 110,000 people through the first six months of 2006, including growth of 15,000 individuals in the second quarter.

• Uniprise increased the number of people it serves in the national multilocation employer segment by 90,000 in the second quarter, bringing year-to-date organic growth to 490,000 new consumers. Uniprise and UnitedHealthcare together have grown their employer-sponsored health benefits businesses by 715,000 people through the first six months of 2006.

• Participation in consumer-driven health plan products grew by 175,000 people in the second quarter and reached 1.8 million people across UnitedHealth Group businesses as of June 30, 2006, reflecting growing market response to new approaches that provide clinical and financial transparency along with individual consumer control.

• Uniprise earnings from operations of $218 million grew $33 million or 18 percent year-over-year and $3 million or 1 percent over the first quarter of 2006. The Uniprise operating margin of 15.7 percent expanded 80 basis points year-over-year, reflecting ongoing advances in quality process improvements.

Earnings From Operations	$	186 million		$	182 million		$	130 million
Operating Margin		18.8	%		18.6	%		19.2	%

Key Developments

• Second quarter revenues rose to $990 million, up $312 million or 46 percent year-over-year and $10 million or 1 percent from the first quarter of 2006.

• Specialized Care Services signed new contracts in the second quarter totaling more than $100 million in projected new annual revenue with payers and other entities that represent 2.2 million people. Effective dates of service commence from July 1, 2006 through early 2007.

• In the second quarter, earnings from operations of $186 million increased $56 million or 43 percent year-over-year and $4 million or 2 percent sequentially.

• The Specialized Care Services second quarter operating margin of 18.8 percent remained generally consistent with prior periods, increasing 20 basis points sequentially and decreasing 40 basis points year-over-year. The slight year-over-year margin decrease reflected strong growth in comparatively lower margin service lines, offset by continued gains in quality initiatives and operating efficiencies.

Business Description

Ingenix is a leader in the field of health care data, analysis and application, serving pharmaceutical companies, health insurers and other payers, physicians and other health care providers, large employers and governments.

Quarterly Financial Performance

Earnings From Operations	$	32 million		$	34 million		$	23 million
Operating Margin		15.2	%		17.0	%		13.1	%

Key Developments

• Ingenix revenues increased $36 million, or 21 percent year-over-year, to $211 million in the second quarter of 2006, reflecting strong growth across the full scope of Ingenix product lines.

• The Ingenix contract revenue backlog across its diverse product lines reached more than $1.05 billion at June 30, 2006. This compares to backlog levels of $822 million for the comparable prior-year period and $850 million as of year-end 2005, highlighting growing revenue momentum.

• New sales activity in the second quarter included significant new orders in pharmaceutical safety and research services, decision-support tools, fraud and recovery services, and technologies to collect, analyze and manage medical cost data.

• Ingenix second quarter earnings from operations increased $9 million or 39 percent year-over-year and decreased $2 million or 6 percent sequentially. The second quarter operating margin of 15.2 percent declined 180 basis points from first quarter 2006 and increased 210 basis points year-over-year. The sequential reduction in operating margin in the second quarter was due to increased new product development and marketing activities, as well as the typical seasonal slowdown in shipments of coding and referential products to the physician and provider market segment.

• Ingenix anticipates sequential gains in revenues, earnings from operations and operating margin in the second half of 2006 as compared to the first six months, as product revenues are expected to again increase seasonally in the second half of the year.

Note: The Company began providing Medicare Part D prescription drug insurance coverage on January 1, 2006. As a result of the Medicare Part D benefit design, the Company incurs benefit costs unevenly during the contract year with a disproportionate amount of claims incurred in the first half of the annual contract year. On a full year basis, management estimates that Medicare Part D will generate a 3% to 4% operating margin, however, as a result of the benefit design, Medicare Part D revenues of approximately $3.1 billion generated a negative operating margin of approximately 4% during the first half of 2006.

The “Part D Normalized” results have been presented to enhance comparability with 2005 quarterly results. The “Part D Normalized” results assume that full year Medicare Part D benefit costs are recognized based on actuarially projected utilization over the contract year. Accordingly, “Part D Normalized” results for the first half of 2006 include a pro rata share of management’s estimate of full year 2006 Medicare Part D benefit costs relating to beneficiaries as of June 30, 2006. “Part D Normalized” results are not meant to be considered in isolation or as a substitute for net earnings or diluted net earnings per share prepared in accordance with GAAP.

(a) Represents estimated CMS Medicare Part D risk-share premium adjustment that is recorded under GAAP as results fall within the provisions of the risk-sharing arrangement. This adjustment is not necessary under “Part D Normalized” as medical costs reflect a pro-rata share of estimated annual medical costs.

(b) Represents actual medical costs incurred under the Medicare Part D contract in excess of a pro-rata share of estimated annual medical costs.

(a) Adjusted Cash Flows From Operating Activities is presented to facilitate the comparison of cash flows from operating activities for periods in which the Company does not receive its monthly premium payments from the Centers for Medicare and Medicaid Services (CMS) in the applicable quarter. CMS generally pays their monthly premium on the first calendar day of the applicable month. If the first calendar day of the month falls on a weekend or a holiday, CMS has typically paid the Company on the last business day of the preceding calendar month. As such, GAAP operating cash flows may vary depending upon which payments are received by the Company from CMS during a particular period. Adjusted Cash Flows From Operating Activities presents operating cash flows assuming that each monthly CMS premium payment was received on the first calendar day of the applicable month.

(a) Reflects the impact of FAS 123R, which we adopted effective January 1, 2006.

Note: Starting in 2006, we have reclassified or “grossed up” premium revenue and expenses for a Uniprise account where we have employed third party reinsurance. While this reinsurance contract has been in place for a number of years, recent accounting interpretations suggest this reinsurance arrangement be presented on a gross versus net basis. We have conformed all reporting periods to this practice to make all periods comparable. This change had no impact to reported earnings.
