Armistice Capital, LLC and Steven Boyd report beneficial ownership of 336,000 shares of FibroGen, Inc. common stock, representing 8.31% of the outstanding class based on the issuer's reported share count in its most recent 10-Q. Armistice Capital acts as investment manager to the Master Fund, the direct holder of the shares, and exercises shared voting and dispositive power over the reported securities. Mr. Boyd, as managing member of Armistice Capital, is similarly reported to have shared voting and dispositive power. The Master Fund disclaims direct beneficial ownership due to the investment management arrangement.

Insights
TL;DR: A single investment manager reports an 8.31% stake, signaling a meaningful equity position disclosed under Schedule 13G/A.
Armistice Capital's filing shows it manages a material minority stake in FibroGen through its Master Fund and reports shared voting and dispositive power over 336,000 shares. This is a passive ownership disclosure consistent with Schedule 13G/A practice where the filer states holdings are in the ordinary course of business and not intended to influence control. The reported percentage is calculated using the issuer's share count from its recent 10-Q and therefore reflects a non-trivial ownership level that could be relevant to shareholder composition analyses.
TL;DR: The filing documents joint reporting by manager and individual and clarifies governance/control relationships.
The statement delineates Armistice Capital's role as investment manager and Mr. Boyd's position as managing member, with both acknowledging shared voting and dispositive authority for the reported shares. The Master Fund's disclaimer of direct beneficial ownership due to the investment management agreement is explicitly stated, reducing ambiguity about who holds legal title versus who directs voting and disposition. The joint filing statement confirms responsibility-sharing for amendments and accuracy of reported information.
