ICON plc Provides Update on Vaccine Study

On March 3, 2025, ICON plc, announced that the large-scale next generation COVID vaccine study that was highlighted on our earnings call on February 20, 2025 as actively screening and moving forward as planned, has now also been delayed by the sponsor.  Current information indicates a delay of 90 days, suggesting that the study will re-commence late in Q2 2025.  While the delay will impact our revenue for the first half of 2025, at this time there is no change to our financial guidance for the full year 2025.

This statement contains forward-looking statements, including statements about our financial guidance. These statements are based on management's current expectations and information currently available, including current economic and industry conditions. These statements are not guarantees of future performance or actual results, and actual results, developments and business decisions may differ from those stated in this statement. The forward-looking statements are subject to future events, risks, uncertainties and other factors that could cause actual results to differ materially from those projected in the statements, including, but not limited to, the ability to enter into new contracts, maintain client relationships, manage the opening of new offices and offering of new services, the integration of new business mergers and acquisitions, as well as other economic and global market conditions and other risks and uncertainties detailed from time to time in SEC reports filed by ICON, all of which are difficult to predict and some of which are beyond our control. For these reasons, you should not place undue reliance on these forward-looking statements when making investment decisions. The word "expected" and variations of such words and similar expressions are intended to identify forward-looking statements. Forward-looking statements are only as of the date they are made and we do not undertake any obligation to update publicly any forward-looking statement, either as a result of new information, future events or otherwise. More information about the risks and uncertainties relating to these forward-looking statements may be found in SEC reports filed by ICON, including its Form 20-F, F-1, F-4, S-8, F-3 and certain other reports, which are available on the SEC's website at http://www.sec.gov.
