11-K
Annual Report Classification · 88% confidence The document is an SEC filing titled “Form 11-K,” which is the annual report for an employee benefit plan (The Nebraska Furniture Mart, Inc. Profit Sharing Plan) for the fiscal year ended December 31, 2025. It contains audited financial statements, notes, and the independent auditor’s report—i.e. a full annual report for the plan. While the form number differs from a corporate 10-K, it is nonetheless the plan’s annual report under SEC rules, matching the Annual Report category. FY 2025

11-K
Regulatory Filings Classification · 85% confidence The document is a Form 11-K, which is an annual report for an employee benefit plan filed under Section 15(d) of the Securities Exchange Act. It contains full audited financial statements, footnotes, and schedules. Since Form 11-K is not one of the specific annual financial report types listed (e.g., 10-K) and does not fit other categories like earnings release, proxy, management change, etc., this falls into the general Regulatory Filings category (RNS) as a SEC compliance filing that does not match another specific type.
2026-05-28 English
SD
Regulatory Filings Classification · 95% confidence The document is an SEC Form SD (Specialized Disclosure Report) for conflict minerals under Rule 13p-1. It is neither an annual report (10-K) nor an earnings release, nor any managerial change or governance presentation. Form SD is a specific regulatory filing without a dedicated category in our taxonomy, so it falls under the Regulatory Filings (RNS) catch-all.

8-K - BERKSHIRE HATHAWAY INC (0001067983) (Filer)
Capital/Financing Update Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events that shareholders should know about. The content focuses on the issuance of multiple series of senior notes (debt securities) by Berkshire Hathaway, including details about the notes, underwriting agreement, indenture, and officers' certificates. There is no detailed financial statement or comprehensive financial analysis, but rather an announcement of new debt issuance and related agreements. This fits the category of Capital/Financing Update (CAP), which covers updates on company fundraising and financing activities. The document length is 8858 characters, which is substantial and contains detailed information about the financing event, not just a brief announcement or reference to another report. Therefore, the classification is CAP with high confidence.

424B5 - BERKSHIRE HATHAWAY INC (0001067983) (Filer)
Capital/Financing Update Classification · 95% confidence The document is a prospectus supplement filed pursuant to Rule 424(b)(5) related to a registration statement for a debt offering by Berkshire Hathaway Inc. It details the terms of multiple series of senior notes, including interest rates, maturity dates, redemption options, underwriting discounts, and legal notices. The document is clearly a detailed offering prospectus supplement for a debt issuance, which is a capital raising activity. It is not a financial report, earnings release, or management discussion. It is not a regulatory filing unrelated to financing, nor is it a report publication announcement. The content focuses on the issuance of senior notes, their terms, and related underwriting information, which fits the definition of a Capital/Financing Update (CAP). The document length is substantial and contains detailed financial terms of the offering, not just an announcement or summary. Therefore, the correct classification is CAP with high confidence.
