Insights

Institutional Ownership Analyst

Large passive stake disclosure: 16.5M shares (4.9%) reported.

Capital World Investors is reported as the beneficial owner of 16,524,735 shares, equal to 4.9% of the company’s stated outstanding shares of 339,559,191 as of 03/31/2026. The filing attributes sole voting and dispositive powers to the reporting entity.

Because the position is below 5%, it fits routine institutional disclosure practice. Subsequent 13D/13G amendments or public statements would be the primary items to watch for any change in intent.

beneficially owned regulatory

"CWI is deemed to be the beneficial owner of 16,524,735 shares"

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.

Schedule 13G/A regulatory

"Amendment to a Schedule 13G (13G/A) filing for institutional investors"

A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.

sole dispositive power regulatory

"Sole power to dispose or to direct the disposition of: 16,524,735"

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.
