How asset managers voted at the Old Second Bancorp, Inc. 2025-2026 meeting

Each item below shows how the 212 asset managers that disclosed a Old Second Bancorp, 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 Old Second Bancorp, 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. Proposal to approve on a non- binding, advisory basis, the compensation of the Company's named executive officers, as described in the Company's 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. Shares outstanding are taken from Old Second Bancorp, Inc.’s 10-Q dated 2026-05-05. This page is a static snapshot rebuilt weekly on 02 October 2026; a live search always shows the current data.

At Old Second Bancorp, Inc.'s shareholder meeting held 2026-05-19, in the 2025-2026 proxy season, 212 asset managers reported how they voted in their SEC Form N-PX filings, covering 1,436 separate fund positions. Their filings are grouped here into 8 reported items; because filers word the same ballot item differently, that can be more than the number of items on the ballot. Old Second Bancorp, 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 — Proposal to approve on a non- binding, advisory basis, the compensation of the Company's named… — the reporting funds cast 99.6% of the shares they voted in favour (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). That is the aggregate of those managers' own N-PX disclosures, not the company's certified result, and the funds are a subset of all shareholders.
