Filing Released Lang Actions
SD
Regulatory Filings Classification · 85% confidence The document is a U.S. SEC Form SD (“Specialized Disclosure Report”) filed under Rule 13p-1 concerning conflict minerals. It is a standalone regulatory disclosure filing, not an Annual Report, quarterly/interim report, or any other specific financial report category. It does not fit into categories like ER, IR, 10-K, etc., and contains no officer certifications only. Therefore, it falls under Regulatory Filings (RNS) as a fallback for miscellaneous SEC filings.

8-K - LAM RESEARCH CORP (0000707549) (Filer)
Earnings Release Classification · 95% confidence The document is a Form 8-K filed with the SEC, dated April 22, 2026, reporting the financial results for the fiscal quarter ended March 29, 2026. It includes a press release announcing quarterly financial results (Exhibit 99.1). The document explicitly states it is a Current Report on Form 8-K and includes Item 2.02 (Results of Operations and Financial Condition), which corresponds to an earnings release or quarterly results announcement. The document length is 4089 characters, which is relatively short and primarily contains the announcement and the press release text. This matches the definition of an Earnings Release (ER) as it is the initial announcement of quarterly financial results with key highlights. It is not a full interim report (IR) with comprehensive financial statements and analysis, nor is it a regulatory filing or report publication announcement. Therefore, the correct classification is Earnings Release (ER).
