LAM RESEARCH CORPORATION
LAM RESEARCH CORPORATION appears on the New York Department of State corporate register under DOS ID 1561515. New York classifies the entity as a FOREIGN BUSINESS CORPORATION whose jurisdiction of incorporation is Delaware, so the New York record is an authority to transact business in the state and not an incorporation. The filing that opened it, dated 15 July 1991, is an Application of Authority made under section 1304 of the New York Business Corporation Law. The registration is Active, and the latest status entry and biennial statement are both dated 25 July 2025. Duration is perpetual, the county of principal office on file is New York, and the principal executive office recorded in the register is 4650 Cushing Parkway, Fremont, California 94538, USA. New York records the Delaware incorporation date separately as 8 September 1989. The registered name has not been amended since the 1991 authority filing.
The authority holder is the same legal person that reports to the SEC as Lam Research Corporation, CIK 0000707549, admitted to trading on the Nasdaq Global Select Market under the symbol LRCX. Its Form 10-K for the fiscal year ended 28 June 2026 carries the identical charter name, a Delaware charter, IRS employer identification number 94-2634797 and the same Fremont principal executive office. That filing describes the company as a Delaware corporation, first incorporated in 1980 and headquartered in Fremont, California, which supplies wafer-fabrication equipment, spare parts and process services to semiconductor manufacturers across deposition, etch, strip and clean process steps. Revenue of USD 23,232,690 thousand for the fiscal year ended 28 June 2026 and approximately 23,300 regular full-time employees at 4 August 2026 are consolidated group figures reported by that registrant; they are not attributable to New York activity.
Data availability
The registry facts above come from New York’s published open-data extracts of the corporate register, retrieved 30 September 2026. New York publishes no revenue, employee, activity or financial data for a foreign business corporation, so the business description and the group figures are taken from the registrant’s own annual report on Form 10-K. The only entity type New York records for DOS ID 1561515 is FOREIGN BUSINESS CORPORATION; no other legal form is asserted here.

Shareholders
Shareholders of LAM RESEARCH CORPORATION
The New York Department of State publishes no shareholder, share-capital or beneficial-ownership data for DOS ID 1561515. A foreign business corporation files an Application of Authority and biennial statements in New York, and neither instrument captures share ownership. The state’s corporate stock dataset holds no record at all for this registration.
Because the authority holder is the SEC registrant Lam Research Corporation (CIK 0000707549), ownership of its common stock is partly visible in federal filings — but only partly. Schedules 13D and 13G capture holders that cross 5% of a registered class; Forms 3, 4 and 5 capture directors, officers and 10% holders. Together these disclose reportable positions only. They are not a shareholder register and do not describe the full shareholder base of a company with 1,251,321,000 shares of common stock outstanding at 4 August 2026.
The most recent such filing naming this issuer is a Schedule 13G filed on 30 April 2026 by Vanguard Capital Management LLC, reporting 93,575,293 shares, or 7.49% of the class, as at the event date of 31 March 2026, with sole voting power over 12,419,549 shares. The filer identifies itself as an investment adviser. A position held by an investment adviser is a managed holding on behalf of client funds and accounts; it is not ownership by an ultimate owner and must not be read as one. A Schedule 13G/A filed on 27 March 2026 by The Vanguard Group, Inc. reports nil shares.
No ultimate beneficial owner is identified by New York, by the SEC filings consulted, or by any other source used for this record.
Data availability
Shareholders: not published by New York. Reportable holders above the 5% threshold: available from SEC beneficial-ownership filings, and the most recent one is set out above. Full shareholder base: not publicly available for a company whose shares trade on a public market. Share capital recorded in New York: none. Ultimate beneficial owner: not disclosed.

Officers
Directors and officers of LAM RESEARCH CORPORATION
New York does disclose one officer for this registration. Section 408 of the Business Corporation Law requires a biennial statement to give the name and business address of the corporation’s chief executive officer, and the statement filed for DOS ID 1561515 on 25 July 2025 names the person below. The state’s Active Corporations extract carries the same name in its chief executive field, and the corporate addresses dataset records the entry under address type 3, chief executive officer.
- TIM ARCHER — chief executive officer as named on the biennial statement filed 25 July 2025 (film number 250725001873). Business address on file: 4650 Cushing Parkway, Fremont, California 94538, USA. Nationality: Not disclosed. Date of birth: not disclosed. The same name appears on this registration’s biennial statements filed 19 July 2019, 7 July 2023 and 25 July 2025. The Form 10-K of the same legal person for the fiscal year ended 28 June 2026 was signed on 7 August 2026 by Timothy M. Archer as President, Chief Executive Officer and Director, which corroborates that the officer New York names remains in office.
New York discloses no directors, no secretary and no other officers for a foreign business corporation, and this record contains none. The agent designated for service of process, and the registered agent, is C T Corporation System at 28 Liberty St., New York, NY 10005, most recently changed by certificates of change filed on 28 January 2019. A registered agent is a commercial provider of a service-of-process address; it is not an officer, director, shareholder or owner of the company.
The registrant’s Form 10-K lists further executive officers of the wider Lam Research group. They are deliberately not reproduced here, because no New York filing ties any of them to DOS ID 1561515 and the register names only the chief executive officer.
Data availability
Chief executive officer: disclosed by New York and named above, with the filing date and film number of the statement that discloses him. Directors: not disclosed by New York for a foreign business corporation. Other officers: not disclosed by New York. Nationalities and dates of birth: not disclosed by New York for any officer, and none is inferred here. Registered agent: disclosed and named above. Any statement that officer data is unavailable for this jurisdiction is incorrect for this record.

Group Structure
Group structure of LAM RESEARCH CORPORATION
The New York Department of State publishes no ownership, parent or subsidiary data for DOS ID 1561515. New York’s constituent-entity dataset holds no record for this registration, so the state records no merger or consolidation into or out of this authority, and no name change since 1991.
Data caveat on the provider group tree. The group tree held against this record by the third-party data provider is keyed to a Californian identifier, given as “US CA 2207172”, and not to New York DOS ID 1561515. The provider’s own internal identifier for this record is the same node as that Californian root, so the entire tree hangs from an entity identified by a California state number rather than from the New York authority described on this page. The root name matches this company, but the identifier is not the one the New York register uses, and it is not the Delaware charter either. The California Secretary of State’s business search refused programmatic access when checked on 30 September 2026, so what “US CA 2207172” denotes could not be verified against the California register. The tree’s keying should therefore be treated as unconfirmed, and nothing in it should be read as a New York disclosure.
A primary group list is available instead, from the company’s own SEC filing. Exhibit 21 to the Form 10-K of Lam Research Corporation for the fiscal year ended 28 June 2026, filed on 7 August 2026, lists 40 subsidiaries of the registrant as of 7 August 2026. This is group-level information describing the Delaware registrant Lam Research Corporation and its consolidated subsidiaries. It is not a disclosure about the New York authority, and New York publishes no equivalent. The exhibit is also incomplete by design: it states that, under Item 601(b)(21) of Regulation S-K, the names of some subsidiaries that are not significant in the aggregate have been omitted.
Entities named in that exhibit, with the jurisdiction of operation the exhibit gives for each:
- Austria — Lam Research AG; Lam Research Management GmbH; Lam Research Salzburg GmbH

Where the provider tree and Exhibit 21 both name an entity, the jurisdictions do not always agree. Exhibit 21 records Lam Research International Holding Company, Coventor, Inc. and Silfex, Inc. as Delaware subsidiaries, whereas the provider labels them with California, California and Ohio state identifiers respectively. Those state numbers may be local qualifications rather than charters; the registrant’s own exhibit is the primary statement of jurisdiction and is preferred here.
No ultimate beneficial owner, and no controlling natural person, is identified by New York or by the filings consulted. Lam Research Corporation is itself the top entity of this group in its own SEC filings; its shares are publicly traded and no parent undertaking is disclosed.
Data availability
Parent, ownership and subsidiary data in New York: not published for this registration. Merger or constituent-entity records in New York: none. Subsidiaries of the SEC registrant: available from Exhibit 21 as set out above, at group level, abbreviated under Item 601(b)(21) of Regulation S-K. The provider group tree: keyed to a Californian identifier rather than to DOS ID 1561515, and unverified. Ultimate beneficial owner: not disclosed.
