Actionable Insight • Neutral

The company is narrowly short of the 75% threshold needed to pass the charter amendment. Watch the November 12 reconvened meeting for final vote results; if the proposal fails, management may need to seek alternative governance changes or negotiate with large holders.

Executive Summary

Tempest Therapeutics filed a DEFA14A (definitive additional proxy soliciting materials) reporting that its reconvened special meeting of stockholders on October 14, 2026, was adjourned again due to insufficient votes to approve a charter amendment to lower supermajority voting requirements and permit stockholder action by written consent. The meeting will reconvene on November 12, 2026. The proposal requires 75% of outstanding votes, and with 74.3% of shares present, the company is narrowly short of passage.
