Percentages above are of 38,873,000 shares outstanding, as reported by Quanterix Corporation on its Form 10-Q dated June 30, 2025 (see the filing on EDGAR). This is the count contemporaneous with the 2025-2026 meeting, not today’s. Each holding is as of its own filing, which may be dated before or after the meeting.
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 Corporation’s 10-Q dated June 30, 2025. This page is a static snapshot rebuilt weekly on November 1, 2026; a live search always shows the current data.
At Quanterix Corporation's 2 shareholder meetings in the 2025-2026 proxy season (held September 29, 2025 and June 9, 2026), 174 asset managers reported how they voted on 13 ballot items in their SEC Form N-PX filings, covering 2,020 separate fund positions. On the most widely held item of the season, voted at the meeting held September 29, 2025 — Approval, on an advisory basis, of the compensation of the Company's named executive officers. — FOR was 85% 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.
