Astria Therapeutics, Inc. Form 8-K Filing

This filing details a Form 8-K report by Astria Therapeutics, Inc., dated December 17, 2025. It supplements a definitive proxy statement related to a special meeting of stockholders concerning a merger agreement between Astria Therapeutics, Inc., BioCryst Pharmaceuticals, Inc., and Axel Merger Sub, Inc. The report discloses two lawsuits filed in the Supreme Court of the State of New York: the "Grant Action" and the "Kent Action."

The report also includes cautionary statements regarding forward-looking statements and provides information on where to find additional details about the merger and related filings.
