                       AETNA REPORTS FIRST QUARTER RESULTS

      -     FIRST-QUARTER OPERATING EARNINGS OF $1.92 PER SHARE

      -     FIRST-QUARTER OPERATING EARNINGS, EXCLUDING FAVORABLE RESERVE
            DEVELOPMENT, OF $1.75 PER SHARE, COMPARED WITH THOMPSON/FIRST CALL
            MEAN OF $1.72, A 31 PERCENT INCREASE OVER PRIOR-YEAR QUARTER

      -     FIRST QUARTER NET INCOME OF $2.28 PER SHARE

      -     MEDICAL MEMBERSHIP INCREASE OF 342,000 FROM YEAR-END 2003

HARTFORD, CONN., APRIL 29, 2004 - Aetna (NYSE: AET) today announced first
quarter operating earnings of $1.92 per share. Operating earnings, excluding
favorable reserve development, were $1.75 per share, an increase of 31 percent
compared to the prior year. This increase primarily reflects growth in revenues
in part from increased medical membership, solid underwriting results, and
reduced operating expenses. Net income for the quarter was $2.28 per share
compared to $2.12 in the prior-year period. Operating earnings exclude net
realized capital gains.(1)

"This quarter marks the achievement of two very significant milestones in
Aetna's turnaround: top-line revenue growth and membership growth," said John W.
Rowe, M.D., chairman and CEO. "For the first time in the turnaround, our revenue
increased, by 8 percent to $4.8 billion from the first quarter of 2003. Medical
membership increased by 342,000, or 2.6 percent, to more than 13.3 million from
December 2003, reflecting both momentum in new customer sales and higher
customer retention. We also experienced meaningful increases in membership in
our dental, pharmacy and group insurance products. Our comprehensive medical
cost management programs and our ongoing operating expense management efforts
continue to have a favorable impact on our results.


Aetna/2

"With our strong first quarter performance, we reaffirm our full-year operating
earnings guidance of $6.60 to $6.75 per share."(2)

"We announced this quarter that Aetna will offer the new Medicare-approved
prescription drug discount card on a national basis and that we will improve our
Medicare Advantage offerings to be more competitive.

"We also announced several new initiatives to reduce complexity for and improve
communications with physicians, including a new information resource, a billing
dispute mechanism, and dedicated service centers. And the National Advisory
Committee of Practicing Physicians, recently formed as a direct result of our
`new era of cooperation' agreement with physicians, held its first meeting.

"Finally, we announced Aetna Integrated Health and Disability, an
industry-leading approach to the coordination and delivery of benefits across
medical, disability, behavioral health and pharmacy," Rowe said.

"The execution of our strategy, which centers on a commitment to disciplined
pricing to achieve profitable growth while focusing on the unique needs of each
of our customer markets, is yielding positive results and contributing to solid
top-line growth," said Ronald A. Williams, president.

HEALTH CARE RESULTS

Health Care, which provides a full range of insured and self-insured medical,
dental, pharmacy and behavioral health products and services, reported:

      -     Operating earnings of $288.4 million in the first quarter of 2004,
            compared with $293.3 million in the first quarter of 2003. Excluding
            favorable reserve development of approximately $27 million after tax
            in the first quarter of 2004 and approximately $107 million after
            tax in the first quarter of 2003, operating earnings were $261.4
            million in the first quarter of 2004 and $186.3 million in the first
            quarter of 2003. This increase was due to higher revenue in part
            from increased medical membership, solid underwriting results and a
            decrease in operating expenses.

      -     Net income of $295.5 million in the first quarter of 2004, compared
            with $301.9 million in the first quarter of 2003.

      -     A Commercial Risk Medical Cost Ratio (MCR) of 77.6 percent in the
            first quarter of 2004, compared with 77.0 percent in the first
            quarter of 2003, excluding favorable reserve development in both
            periods, reflecting a slightly higher percentage increase in
            per-member medical costs over premiums. Including development, the
            Commercial Risk MCR was 76.6 percent in the first quarter of 2004
            and 72.0 percent in the first quarter of 2003.

      -     A Medicare MCR of 86.6 percent in the first quarter of 2004,
            compared with 84.4 percent in the first quarter of 2003, excluding
            favorable reserve development in both periods, reflecting higher
            utilization of health care services in the first quarter of 2004.
            Including development, the Medicare MCR was 84.5 percent in the
            first quarter of 2004, compared with 79.0 percent in the first
            quarter of 2003.

      -     Total medical membership of approximately 13.3 million at March 31,
            2004, compared with 13.0 million at December 31, 2003, an increase
            of 2.6 percent.

      -     Total revenues in the first quarter of 2004 of $4.1 billion,
            compared with $3.8 billion in the first quarter of 2003.

Aetna/4

GROUP INSURANCE RESULTS

Group Insurance, which includes Group Life, Disability and Long-Term Care
products, reported:

      -     Operating earnings of $30.8 million in the first quarter of 2004,
            compared with $32.6 million in the first quarter of 2003. Operating
            earnings were lower because of a slightly higher benefit cost ratio
            and higher operating expenses offset in part by higher net
            investment income.

      -     Net income of $38.7 million in the first quarter of 2004, compared
            with $35.1 million in the first quarter of 2003.

      -     Total revenues in the first quarter of 2004 of $484.9 million,
            compared with $457.4 million in the first quarter of 2003,
            reflecting higher premiums associated with an increase in group life
            membership.

LARGE CASE PENSIONS RESULTS

Large Case Pensions, which manages a variety of discontinued and other
retirement and savings products primarily for defined benefit and defined
contribution plan customers, reported:

      -     Operating earnings of $6.1 million in the first quarter of 2004,
            compared with $6.8 million in the first quarter of 2003.

      -     Net income of $8.1 million in the first quarter of 2004, compared
            with $9.8 million in the first quarter of 2003.

TOTAL COMPANY RESULTS

      -     TOTAL REVENUES. Revenues were $4.8 billion in the first quarter of
            2004, compared with $4.5 billion in the first quarter of 2003. The
            growth in revenue reflects both rate increases and a higher level of
            membership, which resulted in an increase of 9 percent in premiums
            and 8 percent in fees.

      -     TOTAL OPERATING EXPENSES. Operating expenses, which include selling
            and general and administrative expenses, were $983.7 million in the
            first quarter of 2004, $36.7 million less than in the first quarter
            of 2003. General and administrative expenses declined by
            approximately $54 million due to ongoing expense initiatives,
            partially offset by approximately $18 million of increased selling
            expenses associated with membership growth.

Aetna/5

      -     CORPORATE INTEREST expense was $16.5 million after tax in the first
            quarter of 2004, compared with $16.8 million in the first quarter of
            2003.

      -     NET INCOME. Aetna reported net income of $365.8 million in the first
            quarter of 2004, compared with $330.0 million in the first quarter
            of 2003.

      -     PRETAX OPERATING MARGIN(4) improved to 10.0 percent in the first
            quarter of 2004, from 8.2 percent in the first quarter of 2003. The
            after-tax operating margin, which represents income from continuing
            operations divided by total revenue, was 6.8 percent in the first
            quarter of 2004, compared with 7.4 percent in the first quarter of
            2003.

Aetna is one of the nation's leading providers of health care, dental, pharmacy,
group life, disability and long-term care benefits, serving approximately 13.3

(1) Operating earnings exclude net realized capital gains from income from
continuing operations. Although the excluded item may recur, management believes
that operating earnings and operating earnings per share provide a useful
comparison of its underlying business performance from period to period.
Management uses operating earnings to

Aetna/6

assess business performance and to make decisions regarding its operations and
allocation of resources among its businesses. Operating earnings is also the
measure reported to the Chief Executive Officer for these purposes. Realized
capital gains and losses arise from various types of transactions primarily in
the course of managing a portfolio of assets that support the payment of
liabilities, but these transactions do not directly relate to the underwriting
or servicing of products for customers and are not directly related to the core
performance of the company's business operations.

The company also displays certain metrics (e.g., medical cost ratios, operating
earnings, operating earnings per share and pretax operating margins) excluding
changes to prior-period health care cost estimates. Each quarter, the Company
re-examines previously established health care cost payable estimates based on
actual claim submissions and other changes in facts and circumstances. Decreases
(increases) in prior periods' estimates represent the effect of favorable
(unfavorable) development of prior period health care cost estimates on current
period results of operations, at each financial statement date. The Company
believes excluding changes to prior period health care cost estimates better
reflects the underlying current-period health care costs.

For a reconciliation of these items to financial measures calculated under
accounting principles generally accepted in the United States of America (GAAP),
refer to the tables on pages 7 to 11 of this release.

(2) Projected operating earnings per share for full year 2004 exclude $17.0
million of net realized capital gains for the first quarter of 2004 and any
future net realized capital gains or losses. The company is not able to project
the amount of future net realized capital gains or losses and cannot therefore
reconcile projected full year 2004 operating earnings to projected income from
continuing operations. The projected operating earnings per share for full year
2004 also exclude approximately $27 million, after tax, of favorable development
of prior-period health care cost estimates for the first quarter of 2004.

(3) Income from discontinued operations of approximately $40 million for first
quarter 2004 reflects the completion of certain Internal Revenue Service audits
associated with businesses previously sold (former Aetna).

(4) In order to provide useful information regarding profitability of the
company on a basis comparable to others in the industry, without regard to
financing decisions, income taxes and amortization of other acquired intangible
assets (each of which may vary for reasons not directly related to performance
of the underlying business), the company's pretax operating margin excludes
interest expense, income taxes and amortization of other acquired intangible
assets. Management also uses pretax operating margin to assess its performance,
including performance versus competitors. Operating earnings used in the pretax
margin calculation also exclude the items noted in footnote 1. For a
reconciliation to margin calculated under GAAP, refer to the tables on page 10
of this release.

ADDITIONAL INFORMATION; CAUTIONARY STATEMENT -- Certain information in this
press release is forward looking, including, without limitation, the projection
of 2004 operating earnings. Forward-looking information is based on management's
estimates, assumptions and projections, and is subject to significant
uncertainties and other factors, many of which are beyond Aetna's control.
Important risk factors could cause actual future results and other future events
to differ materially from those currently estimated by management. Those risk
factors include, but are not limited to: unanticipated increases in medical
costs (including increased medical utilization, increased pharmacy costs,
increases resulting from unfavorable changes in contracting or re-contracting
with providers, changes in membership mix to lower-premium or higher-cost
products or membership-adverse selection; as well as changes in medical cost
estimates due to the necessary extensive judgment that is used in the medical
cost estimation process, the considerable variability inherent in such
estimates, and the sensitivity of such estimates to changes in medical claims
payment patterns and changes in medical cost trends); decreases in membership or
failure to achieve desired membership growth due to significant competition or
other factors; increases in medical costs or Group Insurance claims resulting
from any acts of terrorism; the ability to reduce administrative expenses while
maintaining targeted levels of service and operating performance, and to improve
relations with providers while taking actions to reduce medical costs; the
ability to successfully implement Aetna's new operating model to a projected
growing membership base; lower levels of investment income from continued low
interest rates; adverse government regulation (including legislative proposals
or court decisions eliminating or reducing ERISA pre-emption of state laws that
would increase potential litigation exposure, and other proposals, such as
patients' rights legislation, that would increase potential litigation exposure
or mandate coverage of certain health benefits); adverse pricing actions by
government payors; changes in size, product mix and medical cost experience of
membership in key markets; and the outcome, including any negotiated resolution,
of various litigation and regulatory matters, including ongoing reviews of
business practices by various regulatory agencies. For more discussion of
important risk factors that may materially affect Aetna, please see the risk
factors contained in Aetna's 2003 Annual Report on Form 10-K, on file with the
Securities and Exchange Commission. You also should read Aetna's 2003 Annual
Report on Form 10-K and Aetna's 2004 first quarter report on Form 10-Q when
filed with the Securities and Exchange Commission for a discussion of Aetna's
historical results of operations and financial condition.
