- Sole voting power: 2,091,091 shares
- Shared voting power: 0
- Sole dispositive power: 0
- Shared dispositive power: 2,091,091 shares
The stake is reported under Rule 13d-1(b) by an entity classified as an investment adviser (IA), indicating the shares are held in the ordinary course of business without intent to influence control. Certification is signed by Senior Vice President – Compliance, Beata Markowicz, on 6 Aug 2025.
