6-K
Regulatory Filings Classification · 80% confidence The document is a U.S. SEC Form 6-K from a foreign private issuer, Nexa Resources S.A., filed under the Securities Exchange Act to furnish information (here including proxy statement exhibits). A Form 6-K is a general regulatory filing rather than a full annual report or any of the other specified disclosure types. There is no dedicated category for Form 6-K, so it falls under the fallback “Regulatory Filings” category (RNS).

Environmental & Social Information Classification · 90% confidence The document is a Form 6-K, which is a report of a foreign private issuer filed with the U.S. SEC under the Securities Exchange Act of 1934. It is dated April 24, 2026, and includes a signature from the CFO. The exhibit index references the publication of the 2025 Sustainability Report. Form 6-K filings typically provide current reports or updates but are not full annual or interim reports themselves. The mention of the Sustainability Report indicates the content relates to environmental and social performance. Given the document length is short (1902 characters) and it primarily announces the publication of the Sustainability Report, it fits best under Environmental & Social Information (SR).

Report Publication Announcement Classification · 95% confidence The document is a Form 6-K, which is a report of a foreign private issuer filed with the SEC. It references the filing of an Annual Report on Form 20-F for the fiscal year ended 2025 and the publication of a mining report. The document length is 1963 characters, which is relatively short and primarily serves as an announcement of the filing and publication rather than containing the full annual report itself. According to the 'MENU VS MEAL' rule, such a document is classified as a Report Publication Announcement (RPA) rather than the Annual Report (10-K or 20-F) itself.
