Amentum Holdings LLC
Amentum Holdings LLC is a Private limited company (Ltd.) registered in United States under 11721600, and its current status with Virginia State Corporation Commission is active. The company was incorporated on 26 November 2019 and lists its registered address as United States. 3 shareholders are on record for Amentum Holdings LLC, 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. This profile is sourced directly from Virginia State Corporation Commission and was last updated on 29 September 2026.

Shareholders of Amentum Holdings LLC
Three shareholders are currently on record for Amentum Holdings LLC, 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 8.5% — the largest recorded stake — followed by Fidelity Capital Trust-Fidelity Value Fund at 1.1%; the remaining 1 shareholder shown holds 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.
