This communication is filed pursuant to Rule 425 under the United States Securities Act of 1933
Subject Company: PRA Health Sciences, Inc.
(Commission File No. 001-36732)
Date: February 24, 2021
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 public limited company, a public limited company in Ireland (“ICON”) and PRA Health Sciences, Inc., a Delaware corporation
(“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; the risk that regulatory approvals are not obtained or are obtained subject to conditions that are not
anticipated by the parties; potential litigation relating to the potential transaction that 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 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 to be 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.

Securities Act of 1933, as amended.
