      IMS Health Reports Strong Momentum in Second-Quarter 2005,
       With Double-Digit Revenue and Earnings-Per-Share Growth


    FAIRFIELD, Conn.--(BUSINESS WIRE)--July 20, 2005--IMS Health
(NYSE: RX) today announced second-quarter 2005 revenues of $433.3
million, up 14 percent (12 percent constant dollar), compared with
revenues of $379.6 million for the second quarter of 2004.
Second-quarter diluted earnings per share on an SEC-reported basis was
$0.41, up 52 percent, compared with $0.27 in the 2004 second quarter.
Second-quarter adjusted diluted earnings per share was $0.34, compared
with $0.29 per share in the same period of 2004, an increase of 17
percent. Net income on an SEC-reported basis was $93.2 million, up 43
percent compared with net income of $65.1 million in the year-earlier
quarter. On an adjusted basis, net income for the second quarter of
2005 was $77.8 million, up 12 percent, compared with net income of
$69.5 million in the prior year.
    "Our second-quarter results were strong around the world, led by
the U.S. and Europe. In fact, our teams delivered double-digit
reported revenue gains in all regions-the Americas, Europe and Asia
Pacific," said David R. Carlucci, IMS chief executive officer and
president. "IMS's outstanding performance demonstrates our continued
success in delivering essential market intelligence to help clients
with their most critical business decisions. Our momentum is strong,
and we remain confident that we will achieve our financial objectives
for the year."
    Operating income in the second quarter was $103.3 million on an
SEC-reported basis and $110.7 million on an adjusted basis, compared
with operating income of $102.5 million on both an SEC-reported and
adjusted basis in the year-earlier period. Adjusted operating income
excludes a charge of $7.4 million for costs associated with the
proposed merger of IMS and VNU, N.V. Operating income rose 1 percent
on an SEC-reported basis and 8 percent on an adjusted basis (7 percent
constant dollar).
    Adjusted results for the second quarter of 2005 exclude the
merger-related costs mentioned above, certain net pre-tax income items
totaling $5.1 million, and certain net tax benefits of $17.6 million,
including a $24.3 million tax benefit related to a technical
correction Congress passed in the American Jobs Creation Act of 2004
(AJCA).
    Adjusted results for the 2004 second quarter 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, 2005 and 2004, respectively.
    On July 11, 2005, IMS announced a definitive agreement to merge
with VNU, a global information and media company with leading market
positions and recognized brands in marketing information (ACNielsen),
media measurement and information (Nielsen Media Research) and
business information (publications and trade shows). The merger, which
is expected to be completed in the first quarter of 2006, is subject
to the approval of shareholders of IMS and VNU, regulatory approvals
and other customary conditions.

    For the first half of 2005, revenues were $844.3 million, up 14
percent (11 percent constant dollar) over the first six months of
2004. SEC-reported diluted earnings per share for the 2005 first half
was $0.54, compared with $0.61 in the year-earlier period, down 11
percent. Adjusted diluted earnings per share in the 2005 first half
was $0.63, a 17 percent increase over the $0.54 reported in the
prior-year period. On an SEC-reported basis, net income for the first
six months of this year was $123.5 million, compared with $146.2
million for the year-ago period, a 16 percent decrease. On an adjusted
basis, net income for the 2005 first half was $145.9 million, up 11
percent, compared with adjusted net income of $131.0 million in the
first half of 2004.
    For the first six months of 2005, operating income was $200.2
million on an SEC-reported basis and $207.6 million on an adjusted
basis, compared with $198.7 million on both an SEC-reported and
adjusted basis in the year-earlier period. Operating income in the
2005 first half rose 1 percent on an SEC-reported basis and was up 4
percent on an adjusted basis (3 percent constant dollar) from the same
period last year.
    Adjusted results for the 2005 first half exclude the
merger-related costs mentioned above and certain net pre-tax income
items totaling approximately $14.5 million, as well as certain net tax
provisions of approximately $29.5 million, primarily related to the
tax recorded in the first half of 2005 on cash IMS intends to
repatriate under the AJCA. Adjusted results for the first half of 2004
exclude certain net pre-tax income items of approximately $11.3
million and certain net tax benefits of approximately $3.9 million.
See Tables 6 and 8 for a reconciliation between SEC and adjusted
results for the six months ended June 30, 2005 and 2004, respectively.

                              IMS Health
                       NOTES TO FINANCIAL TABLES

    (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 are
        those used by management for the purposes of global business
        decision-making, including developing budgets and managing
        expenditures. Adjusted results exclude certain U.S. GAAP
        measures to the extent that management believes exclusion will
        facilitate comparisons across periods and more clearly
        indicate trends. Although IMS discloses adjusted results in
        order to give a full picture to investors of its business as
        seen by management, these adjusted results are not prepared
        specifically for investors and are not a replacement for the
        more comprehensive information for investors included in IMS's
        U.S. GAAP results. 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.
        Investors interested in management's adjusted results are
        urged to review the detailed reconciliations of the adjusted
        measures to comparable U.S. GAAP results.

    (b) Revenue in 2004 has been reclassified to conform to the 2005
        presentation, including a reclassification of Consulting and
        Services revenue into the other three business lines.
        Consulting and Services revenue was $62.4 million in
        second-quarter 2005, up 35% (33% constant dollar) from $46.2
        million in second-quarter 2004. Consulting and Services
        revenue was $117.1 million in first-half 2005, up 47% (44%
        constant dollar) from $79.6 million in first-half 2004.

    (c) Operating expenses in 2004 reflect a reclassification between
        operating costs and selling and administrative expenses to
        make them comparable with the 2005 presentation.

    (d) In the fourth quarter of 2004, IMS sold its entire interest in
        TriZetto back to the company.

    (e) Losses from investments, net were $0.3 million in the second
        quarter of 2005, relating primarily to management fees for the
        Enterprise investments. This is compared with a net gain of
        $2.1 million in the second quarter of 2004 primarily from the
        sale of certain Enterprise investments, partially offset by
        $0.4 million of management fees for the Enterprise
        investments. For the first six months of 2005, Gains from
        investments, net were $2.4 million relating primarily to a
        $3.0 million gain from the sale of a 20% interest we held in a
        German company (GPI), partially offset by $0.6 million of
        management fees for the Enterprise investments. This is
        compared with a net gain of $8.5 million in the first six
        months of 2004 from the sale of certain Enterprise
        investments. These gains and losses from Enterprise
        investments are excluded from adjusted results because they
        relate to non-strategic investments and are not related to
        IMS's core business operations.

    (f) Merger costs relate to professional fees incurred during the
        second quarter of 2005 in connection with IMS's proposed
        merger with VNU, N.V., as announced on July 11, 2005. These
        costs, and the associated tax benefits, are excluded from
        adjusted results because they were incurred specifically in
        relation to the proposed merger of IMS with VNU, N.V. and are
        not related to IMS's core business operations.

    (g) Other income (expense), net includes $0.0 million and $1.2
        million of expenses for legal fees in the second quarter of
        2005 and 2004, respectively, related to the IRI litigation.
        For the first six months, IRI litigation legal fees were $1.2
        million and $1.6 million in 2005 and 2004, 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 income (expense),
        net excludes a quarterly phasing adjustment of foreign
        currency hedge gains (losses), net of $(5.4) million and
        $(16.3) million in the second quarter and first six months of
        2005, respectively, compared with $1.2 million and $(4.4)
        million in the second quarter and first six months of 2004,
        respectively. 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 is no difference between the
        hedge gains in adjusted and SEC results.

    (h) The tax provision for the second quarter and first six months
        of 2005 includes a tax benefit of $1.2 million and a tax
        provision of $2.0 million, respectively, related to the
        Enterprise investments described in note (e) and the items
        described in notes (f) and (g). The tax provision for the
        second quarter and first six months of 2004 includes a tax
        benefit of $0.2 million and a tax provision of $4.0 million,
        respectively, related to the items described in notes (e) and
        (g). These tax provisions are excluded from adjusted results
        because the related charges and gains are excluded from
        adjusted results. The tax provision in the first six months of
        2005 also included a $29.3 million tax benefit related to a
        favorable audit resolution in Japan of the tax years through
        2003. Adjusted results include a phasing adjustment to
        recognize this benefit ratably throughout the year; the
        phasing adjustment for the second quarter and first six months
        of 2005 was $(7.8) million and $15.3 million, respectively.
        This phasing adjustment allows the full year effective tax
        rate to be applied in each quarter to adjusted pretax results.
        Also in the first six months of 2005, $42.8 million of tax
        expense was recorded related to the decision to repatriate
        approximately $650 million of foreign earnings back to the
        U.S. during 2005 under the American Jobs Creation Act of 2004
        (AJCA), including a tax benefit of $24.3 million recorded in
        the second quarter as a result of Congress passing a technical
        correction to the AJCA. As the AJCA is a one-time event, this
        tax expense has been 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. The
        phasing adjustment for the second quarter of 2004 was $(4.2)
        million and $7.9 million for the first six months of 2004.
