FORM 8-K
Regulatory Filings Classification · 95% confidence The document is a Form 8-K Current Report filed with the SEC, which is used for reporting unscheduled material events or corporate changes that are important to shareholders. The text includes details about a definitive agreement for a business combination transaction, press release information, and references to proxy statements and registration statements related to the transaction. It does not contain full financial statements or detailed financial performance data typical of Annual Reports (10-K) or Interim Reports (IR). It also is not a transcript, audit report, or other specific report types. The document is a regulatory filing reporting a significant corporate event (business combination agreement) and related disclosures. Therefore, the appropriate classification is Regulatory Filings (RNS). The document length (15,000 characters) and content confirm it is not merely an announcement of a report but a substantive regulatory filing.

425 Filing
Regulatory Filings Classification · 95% confidence The document is a Form 8-K filed with the SEC, which is a Current Report pursuant to the Securities Exchange Act of 1934. It reports a significant corporate event: a definitive agreement for a business combination (merger/acquisition) involving SilverBox Corp IV and Parataxis Holdings LLC. The text includes details about the transaction, forward-looking statements, and references to proxy statements and registration statements related to the business combination. There are no financial statements or detailed financial analysis present, but rather an announcement of a material event and related disclosures. This fits the category of a Regulatory Filing (RNS) as it is a general regulatory announcement and does not fit into more specific categories like M&A filings (which are typically Forms 425, DEFM14A, SC 14D9, etc.), nor is it a proxy solicitation or voting results announcement. The document is substantive and longer than 5,000 characters, so it is not merely a report publication announcement. Therefore, the best classification is Regulatory Filings (RNS).
