[SCHEDULE 13G/A] Roblox Corporation SEC Filing

Rhea-AI Filing Summary

FMR LLC, together with Chair & CEO Abigail P. Johnson, submitted Amendment No. 7 to Schedule 13G for Regeneron Pharmaceuticals (REGN). The group reports beneficial ownership of 3,359,562.56 common shares, representing 3.2 % of the class as of 30 Jun 2025, and therefore affirms “ownership of 5 percent or less.”

FMR discloses sole voting power over 3,156,857.64 shares and sole dispositive power over the full 3,359,562.56 shares; no shared voting or dispositive authority exists. The position is held in the ordinary course of business under Rule 13d-1(b) and is not intended to influence control of the issuer. Signatures were executed by attorney-in-fact Richard Bourgelas on 5 Aug 2025.

Key takeaway: Fidelity-affiliated entities remain a significant institutional holder, yet their stake has slipped below the 5 % threshold that would otherwise trigger a Schedule 13D filing.

Positive

• None.

Negative

• FMR LLC’s ownership fell to 3.2 %, dropping below the 5 % threshold, indicating a reduction of institutional support or possible share sales.

Insights

Financial Analyst

TL;DR – Fidelity now owns 3.2 % of REGN, down from >5 %, signaling modest divestment but still a sizeable long-term stake.

The filing confirms that FMR LLC and Abigail P. Johnson collectively control 3.36 m REGN shares. Moving below the 5 % mark eliminates additional reporting burdens and can indicate either measured selling or issuer share count changes. With sole voting and dispositive authority, Fidelity remains an influential top-tier shareholder, yet the reduced stake may lessen any perception of an activist role. Because REGN’s float exceeds 100 m shares, a 3 % position is material but unlikely, on its own, to move the stock. Overall impact: modestly negative sentiment due to reduced institutional ownership but fundamentally neutral for long-term outlook.
