Item 1. Legal Proceedings

Apraglutide

On October 2, 2025, Ferring International Center S.A., or Ferring, filed a complaint against our wholly-owned subsidiary, VectivBio AG, for trade secret misappropriation and correction of patent inventorship and ownership in the U.S. District Court in the Eastern District of Texas (Case No. 2:25-cv-01001-RWS-RSP), alleging that VectivBio AG misappropriated Ferring’s technology for its own benefit and improperly filed patent applications claiming that technology without reference to Ferring’s inventorship and ownership interests. Ferring is seeking monetary damages, a declaratory order regarding ownership of certain intellectual property Ferring purports to own, an injunction ordering the transfer or control of such intellectual property, a constructive trust, and certain exemplary damages and costs. We dispute the claims raised in the complaint and intend to vigorously defend our intellectual property rights.
