Insights
Large passive stake reported by Arrowstreet across advisory clients
Arrowstreet reports 8,533,736 shares beneficially owned, with 8,378,951 shares of sole voting power and 8,533,736 shares of sole dispositive power as stated. The filing identifies holdings as held for ASC advisory clients and ACH as parent.
Holder disclosures show investor-level control metrics but attribute economic ownership to multiple clients; subsequent filings could disclose client identities if any exceed 5% individually.
Filing clarifies voting and disposition authority
The Schedule 13G lists sole voting power of 8,378,951 shares and sole dispositive power of 8,533,736 shares, indicating Arrowstreet exercises voting and sale authority for the reported block. The statement also notes no known single client holds >5%.
Because the filing is passive reporting under Rule 13G, it signals institutional accumulation but does not, by itself, reflect any planned corporate action.

Schedule 13Gregulatory
"This Schedule is filed by ASC, in its capacity as investment adviser"
A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.
Beneficially ownedfinancial
"Amount beneficially owned: 8,533,736"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
Sole dispositive powerregulatory
"Sole power to dispose or to direct the disposition of: 8,533,736"
Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.
