Options at notional value: the value of the shares the contracts control, as filers report them, not what the options cost. Not included in the holders, shares or buying above.

Major shareholders (over 5%)

Anyone who owns more than 5% of a class of the company's shares has to say so: on Schedule 13D if they may try to influence or control the company, on 13G if they're a passive investor, and update it as the stake changes. Each holder's latest filing, from 19 Dec 2024 on; percentages are of the share class, as the holder worked them out.

No one currently above 5% in the filings since 19 Dec 2024.

Fell to 5% or below in the last year: GOLDMAN SACHS GROUP INC (0.0%, 2025-11-14), Pentwater Capital Management LP (0.0%, 2025-11-14)
