Mammoth Energy Services, Inc. 2024-2025 Proxy Voting Records

At Mammoth Energy Services, Inc.'s shareholder meeting held June 11, 2025, in the 2024-2025 proxy season, 81 asset managers reported how they voted in their SEC Form N-PX filings, covering 710 separate fund positions. Their filings are grouped here into 7 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 AN ADVISORY BASIS, THE COMPANY'S EXECUTIVE COMPENSATION — Mammoth Energy Services, Inc.'s filing reports the proposal as approved, with 99% support 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). Source: Mammoth Energy Services, Inc.'s Form 8-K, Item 5.07, filed with the U.S. Securities and Exchange Commission on June 12, 2025.

How asset managers voted at the Mammoth Energy Services, Inc. 2024-2025 meeting

Each item below shows how the 81 asset managers that disclosed a Mammoth Energy Services, 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 Mammoth Energy Services, 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.
