How asset managers voted at the NorthWestern Energy Group, Inc. 2025-2026 meetings

Each item below shows how the 412 asset managers that disclosed a NorthWestern Energy Group, 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 NorthWestern Energy Group, 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.

Fund voting reports and institutional-manager reports both cover this item. An institutional manager can report shares that a fund it advises also reports, so the two are shown separately below and never added together, and their sum is not shown (fund and manager reports combined may count the same shares twice). The figure above is FOR ÷ (FOR + AGAINST + WITHHELD) of the shares these managers voted; abstained and unvoted shares are in neither half, and these managers are a subset of all shareholders, not the meeting result.

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 NorthWestern Energy Group, Inc.’s 10-Q dated April 24, 2026. This page is a static snapshot rebuilt weekly on October 14, 2026; a live search always shows the current data.

At NorthWestern Energy Group, Inc.'s 2 shareholder meetings in the 2025-2026 proxy season (held April 2, 2026 and April 30, 2026), 412 asset managers reported how they voted in their SEC Form N-PX filings, covering 6,206 separate fund positions. Their filings are grouped here into 20 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 of the season, voted at the meeting held April 30, 2026 — Advisory vote to approve named executive officer compensation. — FOR was 98% 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.
