Item 8.01

Other Events.

As previously disclosed, on February 24, 2021, PRA Health Sciences, Inc., a Delaware corporation (“PRA”) entered into an Agreement and Plan of Merger (the “Merger Agreement”) with ICON plc, a public limited company in Ireland (“ICON”), ICON US Holdings Inc., a Delaware corporation and subsidiary of ICON (“US HoldCo”), and Indigo Merger Sub, Inc., a Delaware corporation and subsidiary of ICON and US HoldCo (“Merger Subsidiary”). Upon the terms and subject to the conditions of the Merger Agreement, Merger Subsidiary will merge with and into PRA (the “Merger”), with PRA surviving as a subsidiary of ICON and US HoldCo.

The completion of the Merger is conditioned upon, among other things, the approval of the Merger having been granted by the French Ministry of Economy and Finance and the Austrian Federal Ministry for Digital and Economic Affairs, in each case relating to the consummation of the Merger. These approvals have been obtained, and we have now obtained all regulatory approvals that are conditions to the closing of the Merger.

The completion of the Merger remains subject to other customary closing conditions, including the adoption of the Merger Agreement by PRA’s stockholders and the approval by ICON’s shareholders of the issuance of ICON ordinary shares in the Merger. PRA expects the merger to close on July 1, 2021.

Cautionary Note Regarding Forward-Looking Statements

This communication contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements generally include statements regarding the potential transaction between ICON and PRA, including any statements regarding the expected timetable for completing the potential transaction, the ability to complete the potential transaction, the expected benefits of the potential transaction (including anticipated synergies, projected financial information and future opportunities) and any other statements regarding ICON’s and PRA’s future expectations, beliefs, plans, objectives, results of operations, financial condition and cash flows, or future events or performance. These statements are often, but not always, made through the use of words or phrases such as “anticipate,” “intend,” “plan,” “believe,” “project,” “estimate,” “expect,” “may,” “should,” “will” and similar expressions. All such forward-looking statements are based on current expectations of ICON’s and PRA’s management and therefore involve estimates and assumptions that are subject to risks, uncertainties and other factors that could cause actual results to differ materially from the results expressed in the statements. Key factors that could cause actual results to differ materially from those projected in the forward-looking statements include the ability to obtain the requisite ICON and PRA stockholder approvals; uncertainties as to the timing to consummate the potential transaction; the risk that a condition to closing the potential transaction may not be satisfied; litigation relating to the potential transaction that has been or could be instituted against ICON, PRA or their respective directors; the effects of disruption to ICON’s or PRA’s respective businesses; restrictions during the pendency of the potential transaction that may impact ICON’s or PRA’s ability to pursue certain business opportunities or strategic transactions; the effect of this communication on ICON’s or PRA’s stock prices; transaction costs; ICON’s ability to achieve the benefits from the proposed transaction; ICON’s ability to effectively integrate acquired operations into its own operations; the ability of ICON or PRA to retain and hire key personnel; unknown liabilities; and the diversion of management time on transaction-related issues. Other important factors that could cause actual results to differ materially from those in the forward-looking statements include the effects of industry, market, economic, political or regulatory conditions outside of ICON’s or PRA’s control (including public health crises, such as pandemics and epidemics); risks regarding PRA’s ability to maintain large customer contracts or enter into new contracts; PRA’s ability to attract suitable investigators and patients for its clinical trials; PRA’s ability to keep pace with rapid technological change; PRA’s potential liability if a patient is harmed; and the factors set forth under the heading “Risk Factors” of ICON’s Annual Report on Form 20-F and PRA’s Annual Report on Form 10-K and most recent Quarterly Report on Form 10-Q, and in subsequent filings with the U.S. Securities and Exchange Commission (the “SEC”). These risks, as well as other risks associated with the potential transaction, are more fully discussed in the joint proxy statement/prospectus filed with the SEC in connection with the proposed transaction. Other unpredictable or unknown factors not discussed in this communication could also have material adverse effects on forward-looking statements. Neither ICON nor PRA assumes any obligation to update any forward-looking statements, except as required by law. Readers are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof.

No Offer or Solicitation

This communication does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended.

Each of ICON and PRA commenced mailing copies of the definitive joint proxy statement/prospectus to stockholders of ICON and PRA, respectively, on or about April 28, 2021. ICON and PRA may also file other documents with the SEC regarding the potential transaction. This communication is not a substitute for the joint proxy statement/prospectus or registration statement or for any other document that ICON or PRA have filed or may file with the SEC in connection with the potential transaction.
