Shareholders
5
Five shareholders are currently on record for VICOR CORPORATION, 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 Blackrock Inc., holding 15.8% — the largest recorded stake — followed by Vanguard Group Inc at 10.8%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 6 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.

The Treasurer of VICOR CORPORATION currently on record is JAMES SIMMS; five officers are currently on record for VICOR CORPORATION, filed with California Secretary of State — bizfile Online.
The register reports 38 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at VICOR CORPORATION 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
VICOR CORPORATION has no recorded parent company — it sits at the top of its own group structure, with 20 subsidiaries recorded beneath it across 11 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 20 subsidiaries span United States, China, Taiwan, United Kingdom, France, Japan, and 5 more 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.
