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 QUANTERIX CORP.’s 10-Q dated 2024-03-31. This page is a static snapshot rebuilt weekly on 02 October 2026; a live search always shows the current data.

At QUANTERIX CORP.'s shareholder meeting held 2024-06-03, in the 2023-2024 proxy season, 216 asset managers reported how they voted on 4 ballot items in their SEC Form N-PX filings, covering 1,120 separate fund positions. On the most widely held item on that ballot — To approve, by a non-binding advisory vote, the compensation of our named executive officers… — 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. Source: QUANTERIX CORP.'s Form 8-K, Item 5.07, filed with the U.S. Securities and Exchange Commission on 2024-06-07.
