Insights
Large passive stake disclosed by Citadel-related entities and Kenneth Griffin.
The filing documents 6.9M-share holdings reported with shared voting and dispositive power, each tagged as 7.1% of the class using the issuer's outstanding share count as of April 21, 2026. This is a standard beneficial-ownership disclosure under Schedule 13G.
Impact depends on future changes in holdings or voting arrangements; subsequent filings would show purchases, dispositions, or changes to voting power.
Joint filing clarifies entity relationships and shared control signals.
The statement explains the ownership chain (portfolio manager, holding and GP entities) and notes shared power rather than sole voting/dispositive authority. It also includes an attorney-in-fact signature for Mr. Griffin via a previously filed power of attorney.
Governance implications are factual: the filing documents ownership structure; any governance effect will depend on future voting or scheduling disclosures.

"joint Schedule 13G reports that Citadel-related reporting persons may beneficially own"
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 ownfinancial
"may be deemed to beneficially own 6,902,504 Shares"
Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

attorney-in-factlegal
"Seth Levy is signing on behalf of Kenneth Griffin as attorney-in-fact"
An attorney-in-fact is the person or entity given legal authority through a power of attorney to act on behalf of another for specific tasks, such as signing documents, voting shares, or handling transactions. For investors, this matters because it lets a trusted representative make timely decisions or complete paperwork when the owner cannot, much like handing keys to someone to run errands on your behalf—so checks on scope and limits of that authority are important.
