Cabaletta Bio, Inc. 2025-2026 Proxy Voting Records

At Cabaletta Bio, Inc.'s shareholder meeting held June 9, 2026, in the 2025-2026 proxy season, 82 asset managers reported how they voted in their SEC Form N-PX filings, covering 347 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 a non-binding, advisory basis, the compensation of our named executive officers. — FOR was 51.3% 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.

How asset managers voted at the Cabaletta Bio, Inc. 2025-2026 meeting

Each item below shows how the 82 asset managers that disclosed a Cabaletta Bio, 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 Cabaletta Bio, 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.
