How asset managers voted at the TANDEM DIABETES CARE INC. 2024-2025 meeting

Each item below shows how the 349 asset managers that disclosed a TANDEM DIABETES CARE 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 TANDEM DIABETES CARE 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. To approve, on a non-binding, advisory basis, the compensation of our named executive officers.

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 TANDEM DIABETES CARE INC.’s 10-Q dated 2025-03-31. This page is a static snapshot rebuilt weekly on 02 October 2026; a live search always shows the current data.

At TANDEM DIABETES CARE INC.'s shareholder meeting held 2025-05-21, in the 2024-2025 proxy season, 349 asset managers reported how they voted in their SEC Form N-PX filings, covering 3,503 separate fund positions. Their filings are grouped here into 14 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 97% 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.
