Activist meets distress Mixed ◆ strength 0.55

An activist has arrived at a company that needs cash — a potential catalyst, but any financing terms may favour the newcomer. A new active >5% holder appeared while the company is under cash or listing pressure - the classic precursor to a recapitalization, board change, or takeover at a discount.

Would confirm: 13D/A with a plan (Item 4), DEFC14A proxy contest, or 8-K 5.02 board seats.
Would invalidate: 13D/A showing the position sold down.
