Shareholders
5
Five shareholders are currently on record for PERMA-FIX ENVIRONMENTAL SERVICES, INC., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 12% — the largest recorded stake — followed by iShares Trust-iShares Russell 2000 ETF at 5.4%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 8 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.

Management authority at PERMA-FIX ENVIRONMENTAL SERVICES, INC. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
PERMA-FIX ENVIRONMENTAL SERVICES, INC. has no recorded parent company — it sits at the top of its own group structure, with 22 subsidiaries recorded beneath it across 1 jurisdiction. 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 22 subsidiaries span United States jurisdiction, 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. Two of the 22 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
