How asset managers voted at the Columbia Banking System, Inc. 2025-2026 meetings

Each item below shows how the 521 asset managers that disclosed a Columbia Banking System, 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 Columbia Banking System, 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 Columbia Banking System, Inc. shareholders voting in 2025-2026

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 Columbia Banking System, Inc.’s 10-Q dated March 31, 2026. This page is a static snapshot rebuilt weekly on October 14, 2026; a live search always shows the current data.

At Columbia Banking System, Inc.'s 2 shareholder meetings in the 2025-2026 proxy season (held July 21, 2025 and May 14, 2026), 521 asset managers reported how they voted in their SEC Form N-PX filings, covering 7,675 separate fund positions. Their filings are grouped here into 19 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 May 14, 2026 — To approve, on an advisory basis, the compensation of Columbia Banking System, Inc.'s named… — 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: Columbia Banking System, Inc.'s Form 8-K, Item 5.07, filed with the U.S. Securities and Exchange Commission on May 15, 2026.
