Actionable Insight • Neutral

This is a routine governance filing with no immediate trading catalyst. Monitor the EGM on October 2 for any unexpected proposals, but the sole agenda item (board election) is non-controversial. The pipeline updates are backward-looking and do not change the near-term outlook. No action required.

Executive Summary

AC Immune SA filed a 6-K announcing an Extraordinary General Meeting (EGM) on October 2, 2026, to elect Tom Graney to the Board of Directors and the Audit and Finance Committee, replacing Carl June who is stepping down. This is a routine governance filing involving a board member change with no material financial impact. The filing also recaps recent pipeline progress (FDA Fast Track for ACI-7104, Phase 1 data for ACI-19764, ongoing ACI-24 trial) but these are descriptive updates, not new catalysts.
