ASPEN AEROGELS, INC.
ASPEN AEROGELS, INC. is a Public Limited Company registered in United States under 000979392, and its current status with Massachusetts Secretary of the Commonwealth is active. The company was incorporated on 5 June 2008 and lists its registered address as United States. 4 shareholders are on record for ASPEN AEROGELS, INC., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn.

Shareholders
4
Four shareholders are currently on record for ASPEN AEROGELS, 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 Kim, LLC , holding 18.8% — the largest recorded stake — followed by Vanguard Group Inc at 8.3%; the remaining 2 shareholders shown hold smaller stakes.
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
ASPEN AEROGELS, INC. has no recorded parent company — it sits at the top of its own group structure, with 5 subsidiaries recorded beneath it across 3 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 5 subsidiaries span United States, Taiwan, Germany 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.
