Insights

Financial Analyst

TL;DR: Frontier holds a material 9.22% passive stake, with full disposal rights and significant voting exposure on roughly half the position.

Frontier Capital's reported 17,960,663 shares (9.22%) is a material position that can attract market attention because it exceeds the 5% disclosure threshold. The report shows sole dispositive power over the entire holding and sole voting power over 9,034,858 shares, indicating the adviser controls trading decisions and votes a substantial subset of the position. The certification states the holdings are maintained in the ordinary course and not for control, consistent with a passive 13G posture rather than an activist 13D approach. For market participants, this is a notable institutional stake but not, on its face, an intent to change control.

Corporate Governance Expert

TL;DR: A governance-relevant disclosure: a single adviser holds voting influence on ~9.03M shares while disclaiming intent to influence control.

The filing identifies Frontier as an investment adviser with sole dispositive authority and significant sole voting power on roughly half the reported shares. That split—dispositive control of 17,960,663 shares and voting control of 9,034,858—means Frontier can direct trades and will vote a material block at shareholder meetings. The certificate affirms the position is not intended to effect control, which limits immediate governance implications, but the size of the stake means future engagement or voting decisions could be consequential to shareholders and management depending on future actions.
