Holder counts are more reliable. Implied quarter-end price ≈ $0.73. Options: 2 managers hold calls ($9.5k notional), 2 hold puts ($294).

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: BIGGER CAPITAL FUND L P (1.9%, 2026-04-22), ARMISTICE CAPITAL, LLC (5.0%, 2025-11-14)
