SD
Regulatory Filings Classification · 75% confidence The document is a Form SD “Specialized Disclosure Report” filed with the SEC under Rule 13p-1 covering conflict minerals for the period January 1 to December 31, 2025. This is a required regulatory submission (not a full financial report like a 10-K or an Interim Report, nor a simple notice or presentation). There is no dedicated category for Form SD, so it falls under the general “Regulatory Filings” bucket.

8-K - Leidos Holdings, Inc. (0001336920) (Filer)
M&A Activity 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 describes the completion of an acquisition transaction by Leidos Holdings, Inc., including details of the purchase agreement and the transaction amount. It also references a press release about the closing of the transaction. There are no financial statements or detailed financial analysis included, only an announcement of the acquisition completion. This fits the category of M&A Activity announcements rather than a full merger filing or annual report. The document length is under 5,000 characters and is primarily an announcement of a transaction completion, not a detailed report or proxy statement. Therefore, the appropriate classification is M&A Activity (TAR).

Major Shareholding Notification
2026-03-27 English
DEFA14A - Leidos Holdings, Inc. (0001336920) (Filer)
Remuneration Information Classification · 100% confidence The document is a Schedule 14A filing, which is a proxy statement or related materials filed with the SEC. The text explicitly states it is a 'Definitive Additional Materials' related to a proxy statement for Leidos Holdings, Inc. Proxy statements and related materials are classified under 'Remuneration Information' (DEF 14A) filings, as they detail compensation and solicit shareholder votes. The document length is short (1070 characters), consistent with additional proxy materials rather than a full report. Therefore, the correct classification is DEF 14A.
