Insights

Financial Analyst

TL;DR: AQR reports a material passive stake—1.5M shares (6.35%)—with shared voting/dispositive power, disclosed as held in the ordinary course.

The disclosed position of 1,502,205 shares representing 6.35% of the class crosses the 5% reporting threshold and is therefore material from a disclosure perspective. The filing shows no sole voting or dispositive authority and includes a certification the stake is held in the ordinary course of business and not to influence control, consistent with passive Schedule 13G reporting. For investors, this is a significant disclosure of ownership concentration but does not, by itself, indicate activist intent or control efforts.

Corporate Governance Expert

TL;DR: Ownership structure shows shared authority among AQR entities and a formal statement that the holdings are not intended to affect control.

The filing documents shared voting and dispositive power across three affiliated AQR entities and explicitly identifies the parent/subsidiary relationships. The Item 10 certification that the securities are not held to change or influence control is material for governance interpretation: it frames the stake as passive under the filers' representation. This clarifies that routine disclosure requirements are being met without signaling an imminent governance campaign.
