This communication includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Such forward-looking statements reflect, among other things, our current expectations and anticipated results of operations, all of which are subject to known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements, market trends, or industry results to differ materially from those expressed or implied by such forward-looking statements. Therefore, any statements contained herein that are not statements of historical fact may be forward-looking statements and should be evaluated as such. Without limiting the foregoing, the words “anticipates,” “believes,” “can,” “continue,” “could,” “estimates,” “expects,” “intends,” “may,” “might,” “plans,” “projects,” “should,” “would,” “targets,” “will” and the negative thereof and similar words and expressions are intended to identify forward-looking statements. 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. INC Research cautions 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 INC Research and inVentiv to integrate their businesses successfully and to achieve anticipated 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) potential litigation relating to the proposed transaction that could be instituted against INC Research, inVentiv or their respective directors, (vi) possible disruptions from the proposed transaction that could harm INC Research’s and/or inVentiv’s business, including current plans and operations, (vii) the ability of INC Research or inVentiv 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 INC Research’s or inVentiv’s financial performance, (x) certain restrictions during the pendency of the merger that may impact INC Research’s or inVentiv’s 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, will be more fully discussed in the proxy statement that will be filed with the Securities and Exchange Commission in connection with the proposed transaction. While the list of factors presented here is, and the list of factors to be presented in the proxy statement 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 INC Research’s or inVentiv’s consolidated financial condition, results of operations, credit rating or liquidity. Unless legally required, INC Research does not assume any obligation to update any such forward-looking information to reflect actual results or changes in the factors affecting such forward-looking information.
