Regulatory Filings Classification · 75% confidence The document is an SEC Form 8-K “Current Report” filed under the Securities Exchange Act of 1934. It furnishes an earnings press release (Exhibit 99.1) and an investor presentation (Exhibit 99.2) but does not itself contain the full financial statements or investor materials. As a regulatory compliance filing, it falls under the generic Regulatory Filings category (RNS), which serves as a catch-all for filings such as Form 8-K that do not neatly fit into other specific types.

8-K - Core Natural Resources, Inc. (0001710366) (Filer)
Declaration of Voting Results & Voting Rights Announcements Classification · 100% confidence The document is a Form 8-K filed with the SEC, dated April 30, 2026, reporting the submission of matters to a vote of security holders at the Annual Meeting held on the same date. It includes detailed voting results for director elections, appointment of the independent auditor, and advisory approval of executive compensation. The document also references a press release attached as an exhibit. The primary content is the official results from shareholder votes at the Annual Meeting, which aligns with the category for Declaration of Voting Results & Voting Rights Announcements (DVA). The document is not an Annual Report, Earnings Release, or Management Report, but specifically reports voting outcomes. Therefore, the correct classification is DVA with high confidence.
