Cautionary Statements Regarding Forward Looking Statements This communication contains “forward-looking statements” within the meaning of the federal securities laws, including Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. In this context, forward-looking statements often address expected future business and financial performance and financial condition, and often contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “see,” “will,” “would,” “target,” similar expressions, and variations or negatives of these words. Forward-looking statements by their nature address matters that are, to different degrees, uncertain, such as statements about the potential timing or consummation of the proposed transaction or the anticipated benefits thereof, including, without limitation, future financial and operating results. IMS Health and Quintiles caution readers that these and other forward-looking statements are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to risks and uncertainties related to (i) the ability to obtain shareholder and regulatory approvals, or the possibility that they may delay the transaction or that such regulatory approval may result in the imposition of conditions that could cause the parties to abandon the transaction, (ii) the risk that a condition to closing of the merger may not be satisfied; (iii) the ability of IMS Health and Quintiles to integrate their businesses successfully and to achieve anticipated cost savings and other synergies, (iv) the possibility that other anticipated benefits of the proposed transaction will not be realized, including without limitation, anticipated revenues, expenses, earnings and other financial results, and growth and expansion of the new combined company’s operations, and the anticipated tax treatment, (v) current or potential future litigation relating to the proposed transaction that has been or could be instituted against IMS Health, Quintiles or their respective directors, (vi) possible disruptions from the proposed transaction that could harm IMS Health’s or Quintiles’ business, including current plans and operations, (vii) the ability of IMS Health or Quintiles to retain, attract and hire key personnel, (viii) potential adverse reactions or changes to relationships with clients, employees, suppliers or other parties resulting from the announcement or completion of the merger, (ix) potential business uncertainty, including changes to existing business relationships, during the pendency of the merger that could affect IMS Health’s and/or Quintiles’ financial performance, (x) certain restrictions during the pendency of the merger that may impact IMS Health’s or Quintiles’ ability to pursue certain business opportunities or strategic transactions, (xi) continued availability of capital and financing and rating agency actions, (xii) legislative, regulatory and economic developments and (xiii) unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as management’s response to any of the aforementioned factors. These risks, as well as other risks associated with the proposed transaction, are more fully discussed in the preliminary joint proxy statement/prospectus included in the registration statement on Form S-4 filed with the SEC in connection with the proposed transaction. While the list of factors presented here is, and the list of factors presented in the registration statement on Form S-4 are, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on IMS Health’s or Quintiles’ consolidated financial condition, results of operations, credit rating or liquidity. Neither IMS Health nor Quintiles assumes any obligation to provide revisions or updates to any forward looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws. Note on Non-GAAP Financial Measures Non-GAAP results, such as combined adjusted EBITDA, constant currency growth, adjusted income from operations, diluted adjusted EPS and free cash flow, are presented only as a supplement to IMS Health’s and Quintiles’ financial statements based on GAAP. Non-GAAP financial information is provided to enhance understanding of IMS Health’s and Quintiles’ financial performance, but none of these non-GAAP financial measures are recognized terms under GAAP and non-GAAP measures should not be considered in isolation from, or as a substitute analysis for, IMS Health’s and Quintiles’ results of operations as determined in accordance with GAAP. Definitions and reconciliations of non-GAAP measures to the most directly comparable GAAP measures are provided within the schedules attached to this release. IMS Health and Quintiles use non-GAAP measures in their respective operational and financial decision making, and believe that it is useful to exclude certain items in order to focus on what they regard to be a more reliable indicator of the underlying operating performance of the business. As a result, internal management reports feature non-GAAP measures which are also used to prepare strategic plans and annual budgets and review management compensation. IMS Health and Quintiles also believe that investors may find non-GAAP financial measures useful for the same reasons, although investors are cautioned that non-GAAP financial measures are not a substitute for GAAP disclosures. Non-GAAP measures are frequently used by securities analysts, investors and other interested parties in their evaluation of companies comparable to IMS Health and Quintiles, many of which present non-GAAP measures when reporting their results. Non-GAAP measures have limitations as an analytical tool. They are not presentations made in accordance with GAAP, are not measures of financial condition or liquidity and should not be considered as an alternative to profit or loss for the period determined in accordance with GAAP or operating cash flows determined in accordance with GAAP. Non-GAAP measures are not necessarily comparable to similarly titled measures used by other companies. As a result, you should not consider such performance measures in isolation from, or as a substitute analysis for, IMS Health’s and Quintiles’ respective results of operations as determined in accordance with GAAP.
