Ironwood Pharmaceuticals, Inc. (the “Company”) (Nasdaq: IRWD), a biotechnology company developing and commercializing life-changing therapies for people living with gastrointestinal (GI) and rare diseases, today announced that it received a notification letter (the “Notice”) on March 21, 2025 from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that, as a result of the Company’s delay in filing its Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”) with the Securities and Exchange Commission (the “SEC”), the Company is not in compliance with Nasdaq Listing Rule 5250(c)(1) (the “Rule”), which requires Nasdaq-listed companies to timely file all required periodic financial reports with the SEC.

The Notice from Nasdaq is standard practice in the event of a delayed periodic financial report filing. The Notice has no immediate effect on the listing of the Company’s common stock on Nasdaq. Under Nasdaq rules, the Company has 60 calendar days from the date of the Notice, or until May 20, 2025, to submit to Nasdaq a plan to regain compliance with the Rule. The Company plans to file its 2024 Form 10-K as soon as practicable and thereby expects to regain compliance with the Rule.
