How asset managers voted at the CLEAN HARBORS INC. 2023-2024 meeting

Each item below shows how the 488 asset managers that disclosed a CLEAN HARBORS 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 CLEAN HARBORS 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.

1. To approve on a non-binding, advisory basis, the compensation of the Company's named executive officers as described in the Company's definitive proxy statement.

About this page

Every figure above is derived from filings made with the US Securities and Exchange Commission: Form N-PX, in which registered investment companies and institutional managers disclose how they voted every proxy, and Form 8-K Item 5.07, in which the company reports its own meeting results. This page is a static snapshot rebuilt weekly on 02 October 2026; a live search always shows the current data.

At CLEAN HARBORS INC.'s shareholder meeting held 2024-05-22, in the 2023-2024 proxy season, 488 asset managers reported how they voted in their SEC Form N-PX filings, covering 3,672 separate fund positions. Their filings are grouped here into 10 reported items; because filers word the same ballot item differently, that can be more than the number of items on the ballot. On the most widely held item on that ballot — To approve on a non-binding, advisory basis, the compensation of the Company's named executive… — FOR was 95% of the votes cast (FOR divided by FOR plus AGAINST, the conventional basis for proxy support; abstentions, broker non-votes and unvoted shares are excluded because none of them took a side), which is more than half. Whether the item was approved is for the filing to say; that statement has not been read for this item. Source: CLEAN HARBORS INC.'s Form 8-K, Item 5.07, filed with the U.S. Securities and Exchange Commission on 2024-05-23.
