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 QUANTERIX CORP.’s 10-Q dated March 31, 2024. This page is a static snapshot rebuilt weekly on October 18, 2026; a live search always shows the current data.

At QUANTERIX CORP.'s shareholder meeting held June 3, 2024, in the 2023-2024 proxy season, 218 asset managers reported how they voted on 4 ballot items in their SEC Form N-PX filings, covering 1,123 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.
