FORM SD
Regulatory Filings Classification · 94% confidence The document is an SEC Form SD (Specialized Disclosure Report) filed under Rule 13p-1 disclosing conflict minerals for a specified period. It is a mandated regulatory filing that references an exhibit and provides specialized disclosures, rather than being a full financial report, management discussion, or minutes. It does not fit into specific categories like annual reports, earnings releases, ESG reports, or presentations. Therefore it is best classified under the general Regulatory Filings category (RNS).

8-K - MONOLITHIC POWER SYSTEMS INC (0001280452) (Filer)
Audit Report / Information Classification · 95% confidence The document is a Form 8-K Current Report filed with the SEC by Monolithic Power Systems, Inc. It reports a restatement of previously issued financial statements due to an accounting error related to deferred income taxes. The document discusses the impact on prior annual and quarterly financial statements, including the 10-K for the fiscal year ended December 31, 2024, and quarterly 10-Q filings for 2025. It provides detailed restated financial data and reconciliations. The document is not the full annual report itself but a regulatory filing to disclose the restatement and non-reliance on prior financial statements. It is a standalone audit-related disclosure about financial statement restatements and corrections, which fits the category of Audit Report / Information (AR). The document is substantive and lengthy (15,000 characters), not a mere announcement or certification, so it is not Regulatory Filings (RNS) or Report Publication Announcement (RPA). Therefore, the best classification is AR with high confidence.
