SPHERE ENTERTAINMENT CO SPHR

* Summed across managers. Shares that two managers' reports both contain – a subsidiary's holdings that its parent's report includes too, or a sub-adviser's in its client's – are counted once ($21.7m this quarter). Holder counts are more reliable. Implied quarter-end price ≈ $117.30. Options: 11 managers hold calls ($101.2m notional), 15 hold puts ($95.0m).

Trends to Q1 2026

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.
