MONOLITHIC POWER SYSTEMS, INC. is a registered legal entity registered in United States under 1936281, and its current status with California Secretary of State — bizfile Online is inactive. The company was incorporated on 22 August 1997 and lists its registered address as LOS GATOS, United States. 5 shareholders are on record for MONOLITHIC POWER SYSTEMS, 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
5
Five shareholders are currently on record for MONOLITHIC POWER SYSTEMS, 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 Vanguard Group Inc, holding 8.3% — the largest recorded stake — followed by Blackrock Inc. at 7.6%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 45 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
MONOLITHIC POWER SYSTEMS, INC. has no recorded parent company — it sits at the top of its own group structure, with 3 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 3 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.
