These tallies are IMMUNOGEN INC.’s own, as disclosed to the U.S. Securities and Exchange Commission on Form 8-K, filed January 31, 2024 (Item 5.07, “Submission of Matters to a Vote of Security Holders”). They cover every share voted at the meeting, not just the funds that file Form N-PX.

How asset managers voted at the IMMUNOGEN INC. 2023-2024 meeting

Each item below shows how the 335 asset managers that disclosed a IMMUNOGEN 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 IMMUNOGEN 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.

An institutional manager can report shares that a fund it advises also reports, so the two tables can list the same shares and are never added together. Each is ranked by the shares voted on the item that the most managers of that type reported, shown as a share of the 265,842,000 shares outstanding at the time of that meeting.

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 IMMUNOGEN INC.’s 10-Q dated September 30, 2023. This page is a static snapshot rebuilt weekly on October 14, 2026; a live search always shows the current data.

At IMMUNOGEN INC.'s shareholder meeting held January 31, 2024, in the 2023-2024 proxy season, 335 asset managers reported how they voted in their SEC Form N-PX filings, covering 1,157 separate fund positions. Their filings are grouped here into 5 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 — A proposal to approve, on a non-binding, advisory basis, the compensation that may be paid or… — IMMUNOGEN INC.'s filing reports the proposal as not approved, with 43% support 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). Source: IMMUNOGEN INC.'s Form 8-K, Item 5.07, filed with the U.S. Securities and Exchange Commission on January 31, 2024.
