DUBLIN and CHICAGO, March 27, 2026 (GLOBE NEWSWIRE) -- Iterum Therapeutics plc (in Provisional Liquidation) (NASDAQ:ITRM) (the "Company" or "Iterum" or "we"), a company focused on delivering next generation oral and IV antibiotics to treat infections caused by multi-drug resistant pathogens in both community and hospital settings, today announced that it has filed a petition in the High Court in Ireland to wind up the Company. An Order was made appointing Damien Murran and Jennifer McMahon, each of Teneo Restructuring (Ireland) Limited (the "Joint Provisional Liquidators"), as Joint Provisional Liquidators to the Company.

The petition is due to be heard on April 13, 2026. If a winding up order is made by the High Court, the Joint Provisional Liquidators will be confirmed as Joint Liquidators of the Company, and this will result in the winding up and, in due course, the ultimate dissolution of the Company. The Joint Provisional Liquidators were also appointed to the Company's Irish subsidiary, Iterum Therapeutics International Limited (in Provisional Liquidation).

In determining to pursue a wind up, liquidation and dissolution, the Company considered, among other factors, (1) its limited available cash resources and the restrictions on its ability to raise additional capital due to a lack of shares available for issuance and constraints on the authority of the Company's Board of Directors (the "Board") to allot and issue shares following the results of shareholder voting at its recent extraordinary general meeting (the "EGM Voting Results"), (2) its inability to regain compliance with Nasdaq continued listing requirements following the EGM Voting Results, (3) the absence of an alternative strategic transaction acceptable to the Board in the context of the limited time and resources available to the Company and (4) the significant expenses required to continue to fund the Company's business, including for the ongoing commercialization of ORLYNVAH™ against a backdrop of modest sales, and operating as a public company. Although the Company engaged in transaction discussions with two potential counterparties on proposed terms for the acquisition of sulopenem as part of the Company's evaluation of strategic alternatives, neither of the counterparties were able to finalize a definitive agreement and consummate such a transaction on the required timeline and terms, given the limited cash runway for the Company. Therefore, the Board determined that continuing to pursue either transaction was not in the best interests of the Company's creditors and shareholders and the Company has determined that there are no further reasonable avenues available at this time for an alternative strategic transaction outside the context of a liquidation.

It is intended that the Joint Provisional Liquidators will oversee a wind down of the Company's other subsidiaries, Iterum Therapeutics US Holding Limited, Iterum Therapeutics US Limited and Iterum Therapeutics Bermuda Limited.

It is likely that the Joint Provisional Liquidators may decide to manage a withdrawal of ORLYNVAH™ from the U.S. commercial market. Any such withdrawal would be done in accordance with U.S. Food and Drug Administration ("FDA") procedures and in consultation with the relevant third-party service providers including EVERSANA Life Science Services, LLC, and clinicians, as appropriate.

Stakeholders with questions should send any inquiries to the office of the Provisional Liquidators, Teneo Restructuring (Ireland) Limited, at Iterum.Liquidation@teneo.com.
