ICON Schedules Fourth Quarter and Full Year 2025 Earnings Conference Call and Acknowledges Receipt of Deficiency Notice from Nasdaq

Key Terms

annual report on form 20-f regulatory

An annual report on Form 20-F is a standardized filing that foreign companies submit to the U.S. securities regulator to disclose their financial results, business operations, risks, and management’s discussion of performance. It matters to investors because it provides a complete, audited snapshot—like a company’s financial report card and shareholder letter combined—used to assess transparency, compare companies, and judge whether the stock’s price matches underlying business strengths and risks.

nasdaq listing rule 5250(c)(1) regulatory

Nasdaq Listing Rule 5250(c)(1) requires companies listed on the Nasdaq stock exchange to promptly notify the exchange if their stock price falls below a certain minimum level, known as the "initial listing standards." This rule helps ensure that investors are aware of significant declines in a company's stock value, which could signal financial trouble or increased risk. Essentially, it helps maintain transparency and protect investors by keeping them informed about important changes in a company's stock performance.

forward-looking statements regulatory

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

u.s. securities and exchange commission regulatory

The U.S. Securities and Exchange Commission is a government agency responsible for overseeing the stock market and protecting investors. It sets rules to ensure that companies share truthful information and that trading is fair, helping to maintain trust in the financial system. This oversight is important because it helps prevent fraud and ensures that investors can make informed decisions.

DUBLIN--(BUSINESS WIRE)-- ICON plc (NASDAQ: ICLR), a world-leading clinical research organization, today announced that it will release financial results for the fourth quarter and full year 2025 results after the market closes on Wednesday, May 27, 2026. The Company will hold a conference call and webcast to discuss its financial results and performance on Thursday, May 28, 2026 at 8:00am ET.

The Company also announced that, as expected, as a consequence of not yet having filed its Annual Report on Form 20-F for the year ended December 31, 2025 (the “Form 20-F”), the Company has received a written notice from Nasdaq indicating that it is not in compliance with Nasdaq Listing Rule 5250(c)(1) (the “Listing Rule”), which requires timely filing of all required periodic financial reports with the U.S. Securities and Exchange Commission.

The notice has no immediate impact on the listing or trading of the Company’s securities. Nasdaq has provided the Company with 60 calendar days from the date of the notice to submit a plan to regain compliance.

The Company expects to regain compliance upon filing the Form 20-F, which it currently anticipates completing in advance of the conference call.
