Insights

Financial Analyst

TL;DR: Institutional ownership of 4.8% is notable but below the 5% threshold for larger regulatory implications.

State Street’s position of 2,995,144 shares (4.8%) places it among meaningful institutional holders without crossing the common 5% filing threshold for some investor actions. The reported shared voting and dispositive powers and zero sole powers are consistent with an asset manager or custodial arrangement rather than a control stake. For investors, this filing documents ownership concentration but does not, on its face, signal a change in control or an activist intent.

Corporate Governance Expert

TL;DR: The filing reads as a passive, non-control disclosure by a holding company and its advisory subsidiaries.

The schedule classifies the reporting person as HC and lists multiple State Street Global Advisors entities as acquiring subsidiaries, indicating portfolio management activity across funds or accounts. The certification that the shares are held in the ordinary course and not to influence control aligns with a Schedule 13G passive disclosure. The shared voting power of 2,756,191 suggests delegation of voting to pooled accounts or clients rather than unilateral control.
