Rhea-AI Filing Summary

Astria Therapeutics Schedule 13G/A summary: Four reporting persons—RA Capital Management, L.P., RA Capital Healthcare Fund, L.P., Peter Kolchinsky and Rajeev Shah—filed a joint Schedule 13G amendment reporting that they do not beneficially own any shares of Astria Therapeutics common stock. The cover pages show aggregate beneficial ownership of 0 shares, representing 0.0% of the class, and no sole or shared voting or dispositive power is reported. The filing disclaims group status and incorporates a prior joint filing agreement by reference.

Insights

Financial Analyst

TL;DR Reporting persons state zero beneficial ownership in Astria Therapeutics, so no investor position or control influence is indicated.

The Schedule 13G/A is a routine disclosure showing that RA Capital entities and two individuals hold no beneficial shares and report 0.0% ownership. From an investor-significance perspective this filing is neutral: it neither signals accumulation nor divestiture by these parties. The disclaimer of group status and cross-reference to a prior joint filing agreement are procedural and do not change the ownership picture.

Corporate Governance Expert

TL;DR The filing documents no voting or dispositive power and disclaims group status, indicating no governance influence by the filers.

This amendment clarifies governance exposure: none of the reporting persons claims sole or shared voting or dispositive authority over Astria common stock. The explicit 0.0% ownership and the statement that securities are not held to influence control reinforce that these filers are not active participants in corporate governance. The referenced joint filing agreement is procedural for coordinated reporting.
