  *UnitedHealth Group’s full year 2012 revenues of $110.6 billion grew $8.8
    billion or 9 percent year-over-year. Revenue growth accelerated to 11
    percent year-over-year in the fourth quarter, as a result of strong
    advances from UnitedHealthcare Medicare & Retirement, OptumHealth,
    OptumInsight and the continuing development of UnitedHealthcare
    International’s business. Fourth quarter 2012 revenues grew $2.9 billion
    to $28.8 billion.
  *Full year 2012 earnings from operations were $9.3 billion and net earnings
    were $5.5 billion or $5.28 per share. Fourth quarter earnings from
    operations were $2.1 billion and net earnings were $1.2 billion or $1.20
    per share. UnitedHealthcare and Optum exceeded the 2012 revenue and
    earnings outlooks provided in November 2012.
  *Cash flows from operations were $7.2 billion ^ for the full year,
    including $1.7 billion in the fourth quarter. Cash flows from operations
    represented a multiple of 1.3 times 2012 net earnings.
  *Fourth quarter 2012 days sales outstanding in accounts receivable of 9
    days and days claims payable of 49 days both increased by one day
    year-over-year.
  *UnitedHealth Group repurchased 57 million shares for $3.1 billion in 2012
    and paid $820 million in shareholder dividends in 2012, a growth of 26
    percent year-over-year. The full year 2012 return on equity was 18.7
    percent.

  *The full year 2012 commercial medical cost trend was less than 5.5 percent
    and was favorable to management’s forecast. The full year 2012 medical
    care ratio of 80.4 percent decreased 40 basis points year-over-year. The
    fourth quarter 2012 medical care ratio increased 80 basis points
    year-over-year to 80.5 percent. The higher fourth quarter ratio was due to
    a lower level of favorable reserve development: $140 million in fourth
    quarter 2012 compared to $310 million in the fourth quarter of 2011. The
    figures for both periods include $70 million in reserve development from
    prior years.
  *The full year 2012 operating cost ratio of 15.6 percent and the fourth
    quarter ratio of 16.9 percent both increased 30 basis points
    year-over-year, as expected. The increases were driven by changes in
    business mix and investments to transition commercial pharmacy benefit
    management programs to OptumRx and to implement the TRICARE West Region
    contract award in April 2013, partially offset by advances in productivity
    and overall operational efficiency. Spending on reform readiness and
    compliance remained at elevated levels in 2012.
  *The full year 2012 tax rate of 35.9 percent increased 50 basis points, as
    the 2011 rate benefitted from the resolution of various historical tax
    matters.
  *During the fourth quarter the Company purchased approximately 65 percent
    of the outstanding shares of Amil Participacoes S.A. (Amil), the largest
    health care company in Brazil, for $3.5 billion. UnitedHealth Group
    expects to acquire an additional 25 percent interest during the first half
    of 2013 through a tender offer for Amil’s publicly traded shares. The
    remaining 10 percent interest will be retained by Amil’s existing
    management for at least five years.

  *Full year 2012 UnitedHealthcare revenues of $103.4 billion grew $8.1
    billion or 8 percent year-over-year. UnitedHealthcare provided medical
    benefits to 41 million people at year end, having grown by 6.4 million
    people in the past year. Broad-based gains included more than 1 million
    people served in U.S. commercial markets, nearly 1 million people served
    in U.S. public and senior markets and more than 4.4 million people served
    in Brazil via the Amil acquisition. UnitedHealthcare is well positioned to
    continue to grow in 2013 based on initial January 2013 enrollment results.
  *UnitedHealthcare earnings from operations for full year 2012 of $7.8
    billion grew $612 million or 8 percent year-over-year, with fourth quarter
    earnings from operations decreasing $153 million year-over-year to $1.6
    billion due to comparatively lower levels of reserve development in the
    quarter. The full year 2012 operating margin remained consistent at 7.6
    percent for the third consecutive year.

UnitedHealthcare Employer & Individual

  *Full year 2012 UnitedHealthcare Employer & Individual revenues of $46.6
    billion grew $1.2 billion or 3 percent year-over-year. Fourth quarter
    revenues were $11.8 billion.
  *Over the past year, UnitedHealthcare grew its commercial business by
    1,055,000 people. The 2012 full year results included growth of 1,265,000
    people in fee-based offerings, partially offset by a decrease of 210,000
    in risk-based products reflecting funding conversions and
    UnitedHealthcare’s continuing underwriting discipline. Year-end commercial
    enrollment remained unchanged from September 30, 2012.
  *Year-over-year, UnitedHealthcare’s full year 2012 commercial medical care
    ratio of 80.6 percent decreased 30 basis points, while the fourth quarter
    care ratio of 82.8 percent was consistent year-over-year.

UnitedHealthcare Medicare & Retirement

  *UnitedHealthcare Medicare & Retirement revenues of $39.3 billion grew $4.3
    billion or 12 percent year-over-year and $1.3 billion or 15 percent
    year-over-year to $9.8 billion in the fourth quarter. UnitedHealthcare
    continues to rapidly expand the number of senior customers served.

       *In Medicare Advantage, UnitedHealthcare grew to serve 400,000 more
         seniors and other beneficiaries in 2012, an 18 percent year-over-year
         increase, including growth of 25,000 people in the fourth quarter.
       *Growth in active Medicare Supplement products continued, with the
         number of seniors and other beneficiaries served increasing by
         245,000 in 2012, including 45,000 people in the fourth quarter.
       *At December 31, 2012, 4.2 million seniors and other beneficiaries
         participated in the Company’s stand-alone Part D prescription drug
         plans, a decline of 630,000 people year-over-year due to the Company
         pricing higher than the benchmarks for the low income subsidy markets
         in most regions.

UnitedHealthcare Community & State

  *In 2012, Community & State revenues of $16.4 billion grew $1.5 billion or
    10 percent year-over-year, due to strong growth in people served through
    state sponsored benefit programs. Fourth quarter revenues grew $245
    million year-over-year to $4.2 billion.
  *UnitedHealthcare expanded its Medicaid services to 405,000 more people in
    2012, including 60,000 in the fourth quarter. The fourth quarter net
    decrease of 115,000 people included the planned fourth quarter market
    withdrawal from one product in a portion of Wisconsin, affecting 175,000
    beneficiaries. Full year net membership, including this market exit, grew
    by 230,000 people or more than 6 percent in 2012, driven by continued
    local market growth and geographic and product expansion.

UnitedHealthcare International

  *UnitedHealthcare International fourth quarter 2012 revenues of $1.0
    billion represented the initial results from Amil during the quarter as
    well as a small amount of revenues from international businesses already
    owned by UnitedHealthcare. Amil ended the year serving more than 4.4
    million people with medical benefits.

  *In 2012, Optum revenues grew by $735 million or 3 percent to $29.4
    billion, with fourth quarter revenues of $7.5 billion relatively stable
    year-over-year, as expected. Significant growth and business expansions in
    key technology and service categories over the past year were offset by a
    reduction in pharmacy service revenues due to reduced levels of Part D
    prescription drug membership and related prescription volumes.

       *OptumHealth revenues of $8.1 billion grew $1.4 billion or 22 percent
         year-over-year in 2012, including growth of $325 million or 18
         percent year-over-year to $2.1 billion in fourth quarter of 2012.
       *OptumInsight revenues grew to $2.9 billion in 2012, advancing $211
         million or 8 percent year-over-year. Fourth quarter 2012 revenues of
         $822 million accelerated to 15 percent growth year-over-year.
         OptumInsight’s revenue backlog grew 14 percent year-over-year to $4.6
         billion at December 31, 2012, reflecting strong demand for clinical
         systems and compliance and payment integrity services.
       *OptumRx full year 2012 revenues of $18.4 billion decreased 5 percent
         year-over-year due to the reduction in UnitedHealthcare Part D plan
         participants. Fourth quarter 2012 revenues of $4.6 billion decreased
         10 percent year-over-year but grew $125 million or 3 percent from
         third quarter 2012 due to a higher volume of traditional and
         specialty pharmaceutical prescriptions in the fourth quarter.

  *Optum’s 2012 earnings from operations of $1.4 billion grew $178 million or
    14 percent year-over-year and operating margins expanded 50 basis points
    year-over-year. Fourth quarter earnings from operations of $459 million
    grew $180 million or 65 percent year-over-year and operating margin
    expanded 240 basis points to 6.1 percent. Earnings growth and margin
    expansion were driven by revenue growth in higher margin products and by
    improvements in business simplification, integration and efficiency
    efforts that benefitted operating earnings in the second half of 2012.

       *Full year 2012 OptumHealth earnings from operations of $561 million
         grew $138 million year-over-year, and the operating margin improved
         60 basis points to 6.9 percent. Fourth quarter operating earnings of
         $178 million grew $114 million and operating margins expanded nearly
         5 percentage points. Gains in operating efficiency and cost
         management and increased earnings from integrated care delivery were
         principal contributors to the strong margin expansion and earnings
         growth.
       *OptumInsight’s full year 2012 earnings from operations of $485
         million grew $104 million or 27 percent year-over-year and the full
         year operating margin expanded from 14.3 percent to 16.8 percent.
         Fourth quarter operating earnings of $175 million grew $55 million
         and operating margin expanded 460 basis points year-over-year to 21.3
         percent. Growth, favorable business mix and operating and cost
         efficiencies drove full year and fourth quarter 2012 margin expansion
         and overall earnings performance.
       *OptumRx full year 2012 earnings from operations of $393 million
         decreased $64 million year-over-year, as the business absorbed $115
         million in investments to support the transition of UnitedHealthcare
         commercial pharmacy benefits and position OptumRx for broader market
         growth. Fourth quarter 2012 earnings from operations of $106 million
         improved 12 percent year-over-year and the fourth quarter operating
         margin improved 40 basis points to 2.3 percent driven by increasing
         specialty pharmaceutical volume and a 5 percentage point
         year-over-year advance in the use of generic medications, to 81
         percent of total prescription volume in fourth quarter 2012.

Generally the words “believe,” “expect,” “intend,” “estimate,” “anticipate,”

statements, which generally are not historical in nature. These statements may
contain information about financial prospects, economic conditions and trends
and involve risks and uncertainties. We caution that actual results could
differ materially from those that management expects, depending on the outcome
of certain factors.

Some factors that could cause results to differ materially from the
forward-looking statements include: our ability to effectively estimate, price
for and manage our medical costs, including the impact of any new coverage
requirements; the potential impact that new laws or regulations, or changes in
existing laws or regulations, or their enforcement or application could have
on our results of operations, financial position and cash flows, including as
a result of increases in medical, administrative, technology or other costs or
decreases in enrollment resulting from U.S., Brazilian and other
jurisdictions' regulations affecting the health care industry; the impact of
any potential assessments for insolvent payers under state guaranty fund laws;
the ultimate impact of the Patient Protection and Affordable Care Act, which
could materially and adversely affect our results of operations, financial
position and cash flows through reduced revenues, increased costs, new taxes
and expanded liability, or require changes to the ways in which we conduct
business or put us at risk for loss of business; potential reductions in
revenue received from Medicare and Medicaid programs; uncertainties regarding
changes in Medicare, including potential changes in risk adjustment data
validation audit and payment adjustment methodology; failure to comply with
patient privacy and data security regulations; regulatory and other risks and
uncertainties associated with the pharmacy benefits management industry and
our ability to successfully repatriate our pharmacy benefits management
business; competitive pressures, which could affect our ability to maintain or
increase our market share; the impact of challenges to our public sector
contract awards; our ability to execute contracts on competitive terms with
physicians, hospitals and other service professionals; increases in costs and
other liabilities associated with increased litigation, government
investigations, audits or reviews; failure to complete or receive anticipated
benefits of acquisitions and other strategic transactions, including the Amil
acquisition; our ability to attract, retain and provide support to a network
of independent producers (i.e., brokers and agents) and consultants; events
that may adversely affect our relationship with AARP; the potential impact of
adverse economic conditions on our revenues (including decreases in enrollment
resulting from increases in the unemployment rate and commercial attrition)
and results of operations; the performance of our investment portfolio;
possible impairment of the value of our goodwill and intangible assets in
connection with dispositions or if estimated future results do not adequately
support goodwill and intangible assets recorded for our existing businesses or
the businesses that we acquire; increases in health care costs resulting from
large-scale medical emergencies; failure to maintain effective and efficient
information systems or if our technology products otherwise do not operate as
intended; misappropriation of our proprietary technology; our ability to
obtain sufficient funds from our regulated subsidiaries or the debt or capital
markets to fund our obligations, to maintain our debt to total capital ratio
at targeted levels, to maintain our quarterly dividend payment cycle or to
continue repurchasing shares of our common stock; the impact of fluctuations
in foreign currency exchange rates on our reported shareholders' equity and
results of operations; potential downgrades in our credit ratings; and failure
to achieve targeted operating cost productivity improvements, including
savings resulting from technology enhancement and administrative
modernization.

This list of important factors is not intended to be exhaustive. We discuss
certain of these matters more fully, as well as certain risk factors that may
affect our business operations, financial condition and results of operations,
