LAM RESEARCH CORPORATION
LAM RESEARCH CORPORATION is a registered legal entity registered in United States under 973137, and its current status with California Secretary of State — bizfile Online is inactive. The company was incorporated on 21 January 1980 and lists its registered address as FREMONT, United States. 2 shareholders are on record for LAM RESEARCH CORPORATION, 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 of LAM RESEARCH CORPORATION
Two shareholders are currently on record for LAM RESEARCH 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 Fidelity Concord Street Trust-Fidelity 500 Index Fund, holding 2.2% — the largest recorded stake — followed by Fidelity Select Portfolios-Select Semiconductors Portfolio at 1.2%. 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.
