How asset managers voted at the Eos Energy Enterprises, Inc. 2025-2026 meetings

Each item below shows how the 267 asset managers that disclosed a Eos Energy Enterprises, Inc. 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 Eos Energy Enterprises, Inc.’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.

Largest Eos Energy Enterprises, Inc. shareholders voting in 2025-2026

Ranked separately for each type of Form N-PX report. 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 339,459,021 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 Eos Energy Enterprises, Inc.’s 10-Q dated March 31, 2026. This page is a static snapshot rebuilt weekly on October 18, 2026; a live search always shows the current data.

At Eos Energy Enterprises, Inc.'s 2 shareholder meetings in the 2025-2026 proxy season (held October 16, 2025 and June 3, 2026), 267 asset managers reported how they voted in their SEC Form N-PX filings, covering 1,742 separate fund positions. Their filings are grouped here into 9 reported items; because filers word the same ballot item differently, that can be more than the number of items on the ballot. Eos Energy Enterprises, Inc.'s own Form 8-K tally for this meeting is published below, but no row in it could be matched to the most widely held item, so this page states no certified outcome for that item. On that item — Non-binding advisory vote to approve our named executive officer compensation. — the reporting funds and managers cast 52.7% 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.
