Results at a glance

No official results are on file for this meeting: no Form 8-K tally (Item 5.07) from Ero Copper Corp. has been matched to it. The figures below are the funds’ own votes from Form N-PX. They are not the meeting result, so they are not used to judge dissent.

Material dissent: a director nominee under 80% of the votes cast, say-on-pay under 70%, any other item the board put forward under 80%, or a shareholder proposal with more than 50%, on the company’s own Form 8-K tally. How this is decided

How asset managers voted at the Ero Copper Corp. 2025-2026 meeting

Each item below shows how the 96 asset managers that disclosed a Ero Copper Corp. vote in their SEC Form N-PX filings actually voted. Share totals are the shares those managers' funds voted, summed across every fund they report. These are reported items, not a count of the ballot: fund filings describe one ballot item in different words. Two descriptions are shown as one item only on evidence — the same text (or one cut short of the other), the same director nominee, or a match to the same row of Ero Copper Corp.’s own Form 8-K tally — never because they merely read alike. A description that could not be joined that way is listed on its own, so one ballot item can appear more than once.

An institutional manager can report shares that a fund it advises also reports, so the two tables can list the same shares and are never added together. Each is ranked by the shares voted on the item that the most managers of that type reported, shown as a share of the 104,192,288 shares outstanding at the time of that meeting.

About this page

Every figure above is derived from filings made with the US Securities and Exchange Commission: Form N-PX, in which registered funds disclose how they voted every proxy and institutional managers disclose their votes on executive pay (say-on-pay, say-on-frequency and golden parachutes), and Form 8-K Item 5.07, in which the company reports its own meeting results. Shares outstanding are taken from Ero Copper Corp.’s 40-F dated December 31, 2025. This page is a static snapshot rebuilt weekly on October 14, 2026; a live search always shows the current data.

At Ero Copper Corp.'s shareholder meeting held June 29, 2026, in the 2025-2026 proxy season, 96 asset managers reported how they voted in their SEC Form N-PX filings, covering 1,416 separate fund positions. Their filings are grouped here into 22 reported items; because filers word the same ballot item differently, that can be more than the number of items on the ballot. No official Form 8-K vote tally has been matched to this meeting, so this page states no certified outcome for its most widely held ballot item. On that item — To approve a non-binding advisory "say on pay" resolution accepting the Company's approach to… — the reporting funds and managers cast 99.9% of the shares they voted in favour (FOR divided by FOR plus AGAINST plus WITHHELD; abstained and unvoted shares are excluded because neither took a side). Fund and manager reports are combined in it and may count the same shares twice: it adds fund reports to institutional-manager reports, which can cover the same shares. It is not the company's certified result.
