     FAIRFIELD, Conn.--(BUSINESS WIRE)--July 20, 2004--IMS Health (NYSE: RX)
today announced second-quarter 2004 revenues of $379.6 million, up 12 percent (9
percent on a constant-dollar basis) compared with revenues of $337.8 million for
the second quarter of 2003. SEC-reported diluted earnings per share in the 2004
second quarter was $0.27, an increase of 17 percent compared with $0.23 in the
prior-year period. Adjusted diluted earnings per share for the second quarter of
2004 was $0.29, up 16 percent compared with $0.25 in the 2003 second quarter.
Net income for the second quarter of 2004 was $65.1 million on an SEC-reported
basis and $69.5 million on an adjusted basis, compared with net income of $55.4
million on an SEC-reported basis and $60.4 million on an adjusted basis in the

operating income was $102.5 million in the 2004 second quarter, up 5 percent (3
percent constant dollar) from $97.3 million for the year-ago period.
     The company also announced that it is raising its 2004 guidance. IMS now
expects 2004 constant-dollar revenue growth to be within a range of 8 - 10
percent, versus its previously stated estimate of 7 - 9 percent. Adjusted
diluted earnings per share for 2004 is now expected to be in the $1.15 - $1.20
range, up from $1.12 - $1.17. See Note (l) for an explanation of the
reconciliation between expected SEC-reported and adjusted full-year diluted
earnings per share.
     "Once again, we delivered a strong quarter, with our business around the
world showing solid growth and momentum," said David Thomas, IMS chairman and
CEO. "Our new offerings increasingly combine our data assets with consulting and
services skills to generate opportunities for us with new and existing
customers. Demand for our solutions remains strong. We are particularly pleased
with our Global Consulting and Services revenue performance, which grew 50
percent in the first half."
     Adjusted results for the second quarter of 2004 exclude certain net pre-tax
expense items totaling approximately $0.4 million, as well as certain net tax
provisions of approximately $4.0 million. See Tables 5 and 7 for a
reconciliation between SEC and adjusted results for the quarters ended June 30,

                              IMS Health
                                 NOTES

(a) "SEC Income Statement" (Tables 1 and 2) differs from the "Adjusted
    Income Statement" (Tables 3 and 4) by amounts that are detailed on
    Tables 5, 6, 7 and 8. Adjusted results generally exclude from
    corresponding U.S. GAAP measures items that are not related to the
    core business of IMS (such as gains/losses on non-core
    transactions, gains/losses on issuance of investees' stock, a tax
    provision related to D&B legacy and related subsequent tax
    transactions, etc.) and from time to time also have excluded items
    that are related to the core business of IMS but that management
    does not expect to be relevant to the business going forward (such
    as special restructuring, severance, impairment and other
    charges), together with the tax effect of these items. Severance,
    impairment and other charges were recorded in 2000, 2001 and 2003,
    and there can be no assurance that such charges will not be
    recorded in the future. Management uses these adjusted results to
    evaluate its financial results for business decision-making, to
    develop budgets and to manage expenditures with respect to its
    core business. Management believes that the adjusted results are
    useful to investors as a supplement to historical U.S. GAAP
    information because they facilitate comparisons across periods,
    more clearly indicate trends and add insight into the Company's
    performance by focusing on the results generated by the Company's
    core operations. However, the fact that an item has been excluded
    from adjusted results does not mean that similar items will not be
    recorded in the future. The method IMS uses to prepare adjusted
    results differs in significant respects from U.S. GAAP and is
    likely to differ from the methods used by other companies.
    Adjusted results should not be regarded as a replacement for
    corresponding U.S. GAAP measures, which provide more comprehensive
    information about the financial results of IMS. Investors are
    urged to review the detailed reconciliations of the adjusted
    measures to the comparable U.S. GAAP results.

(b) Operating expenses in 2003 reflect a reclassification between
    operating costs and selling and administrative expenses to make
    them comparable with the 2004 presentation.

(c) TriZetto Equity Loss in the second quarter of 2004 is based on an
    estimate of TriZetto's results and includes IMS's share of such
    estimated TriZetto results as well as purchase accounting
    amortization expenses.

(d) IMS divested its equity interest in CTS on February 6, 2003 via a
    split-off transaction. Income from discontinued operations
    includes IMS's share of CTS income on an after-tax basis for the
    portion of the first quarter of 2003 prior to the split-off.
    Previously CTS had been consolidated into the IMS Health financial
    statements.

(e) Gains from investments, net were $2.1 million in the second
    quarter of 2004, relating primarily to an earn-out payment from
    the sale of an Enterprise investment. This is compared with a gain
    of less than $0.1 million in the second quarter of 2003. Gains
    from investments, net were $8.5 million for the first six months
    of 2004, primarily from the sale of a security in the first
    quarter and the items discussed above. This is compared with a
    loss of $0.8 million in the first six months of 2003. These gains
    and losses are excluded from adjusted results because they relate
    to non-strategic investments and are not related to IMS's core
    business operations.

(f) Loss on issuance of investees' stock, net was $0.1 million in the
    second quarter and the first six months of 2004 compared with a
    gain of $0.1 million in the second quarter of 2003 and a loss of
    $0.3 million in the first six months of 2003. These SAB 51 losses
    relate to the exercise of stock options by TriZetto employees and
    TriZetto share repurchases. They are excluded from adjusted
    results because they are not related to IMS's core business
    operations.

(g) Other expense, net includes $1.2 million and $(2.2) million of
    expenses for legal fees in the second quarter of 2004 and 2003,
    respectively, related to the IRI litigation. For the first six
    months, IRI litigation legal fees were $1.6 million and $(1.8)
    million in 2004 and 2003, respectively. These expenses are
    excluded from adjusted results because they relate to a D&B legacy
    matter and are not related to IMS's core business operations. In
    addition, other expense, net excludes a quarterly phasing
    adjustment of foreign currency hedge gains (losses), net of $1.2
    million in the second quarter and $(4.5) million for the first six
    months of 2004, and $4.8 million in the second quarter and $10.6
    million for the first six months of 2003. This phasing adjustment
    is made to adjusted results in order to more closely match the
    timing of foreign exchange hedge gains (losses) with the operating
    income being hedged. For the full year, there will be no
    difference between the hedge gains (losses) in adjusted and SEC
    results.

(h) The tax provision for the second quarter and first six months of
    2004 includes a tax benefit of $0.2 million and tax provision of
    $4.0 million, respectively, related to the items described in
    notes (e), (f) and (g). The tax provision for the second quarter
    and first six months of 2003 includes a tax benefit of $0.9
    million and $3.5 million, respectively, for the items described in
    notes (e), (f) and (g), and a tax benefit of $13.2 million for the
    item in note (i). These tax provisions and benefits are excluded
    from adjusted results because the related charges are excluded
    from adjusted results. In addition, the first-quarter 2004 tax
    provision also includes a $15.6 million tax benefit related to a
    favorable audit resolution in the U.S. of the 1998 and 1999 tax
    years. Adjusted results include a phasing adjustment to recognize
    it ratably throughout 2004. The second quarter phasing adjustment
    was $4.2 million and the phasing adjustment for the first six
    months was $(7.9) million. This phasing adjustment allows the
    full-year effective rate to be applied in each quarter to adjusted
    pretax results. Similarly, the tax provision for the first quarter
    of 2003 included a $13.9 million tax benefit; adjusted results
    included a phasing adjustment to recognize it ratably throughout
    2003. The second-quarter 2003 phasing adjustment was $3.4 million
    and the phasing adjustment for the first six months of 2003 was
    $(7.9) million.

(i) IMS incurred $37.2 million of expense in the first quarter of 2003
    for severance, impairment and other charges, including severance
    for approximately 80 employees, contract cancellations and
    impairments, idle real estate facilities and software writedowns.
    These amounts are excluded from adjusted results because
    management does not expect them to be relevant to the business
    going forward. Severance, impairment and other charges were
    recorded in 2000, 2001 and 2003, and there can be no assurances
    that such charges will not be recorded in the future.

(j) The TriZetto Impairment Charge, net recorded in the first quarter
    of 2003 reduced the book value per share of IMS's investment in
    TriZetto shares ($6.14 per share) down to the March 31, 2003
    market value per share ($4.13). This charge is excluded from
    adjusted results because it relates to a non-strategic investment
    and is not related to IMS's core business operations.

(k) The split-off of CTS described in note (d) generated a net gain of
    $495.1 million in the first quarter of 2003. This gain is
    calculated as the proceeds from the split-off less the book value
    of IMS's investment in CTS and transaction costs. No tax provision
    is provided as the split-off is expected to be a tax-free
    transaction. This gain is excluded from adjusted results as it
    relates to the divestiture of the business and is not related to
    IMS's ongoing core business operations.

(l) IMS expects SEC-reported full-year diluted earnings per share
    ("EPS") to differ from adjusted diluted EPS. For the first six
    months of 2004, the SEC-reported diluted EPS of $0.61 was $0.07
    higher than adjusted diluted EPS of $0.54. See Table 6. This
    difference was due to net gains from IMS investments, legal fees
    relating to the IRI litigation, phasing adjustments of foreign
    currency hedge gains (losses) and phasing adjustments relating to
    a tax benefit. By year-end, it is expected that the $0.01 foreign
    currency hedge gain difference and $0.03 phasing adjustments for a
    tax benefit difference between SEC-reported and adjusted diluted
    EPS for the first six months of 2004 will reverse, resulting in no
    difference in these items between SEC-reported and adjusted
    diluted EPS for the full year. Additional items that could cause
    full-year 2004 SEC-reported diluted EPS to differ from adjusted
    diluted EPS include, but are not limited to, additional IRI legal
    fees and gains or losses resulting from strategic actions with
    respect to IMS's investments. IMS is unable to predict at this
    time the occurrence or amount of these as well as other items that
    could cause full-year 2004 SEC-reported diluted EPS to differ from
    adjusted diluted EPS.

    Statements relating to guidance are based on current expectations
    as of the date of this release. These statements are
    forward-looking, and actual results may differ materially. IMS
    does not undertake to update these targets in any way or for any
    reason prior to discussing actual results.

     Amounts presented in the financial tables may not add due to rounding.

     These financial tables should be read in conjunction with IMS Health's
filings previously made or to be made with the Securities and Exchange
Commission.
