Shareholders
5
Five shareholders are currently on record for BIOSIG TECHNOLOGIES, INC., reflecting the stock ledger kept by the company under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Legacy Wealth Managment, LLC/ID, holding 74.2% — a majority holding — followed by Vanguard Group Inc at 10.7%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 16 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Group Structure
BIOSIG TECHNOLOGIES, INC. has no recorded parent company — it sits at the top of its own group structure, with 3 subsidiaries recorded beneath it across 2 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 3 subsidiaries span United States, Canada jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear.
