Actionable Insight • Neutral

The company continues to fail to secure the 75% supermajority vote needed for the charter amendment, now adjourning twice. Monitor the October 14 reconvened meeting for vote results; failure to pass could signal governance friction and limit the board's flexibility on future actions.

Executive Summary

Tempest Therapeutics adjourned its reconvened special meeting of stockholders on September 15, 2026, because it lacked sufficient votes to approve a charter amendment replacing supermajority voting requirements and permitting stockholder action by written consent. The meeting will reconvene on October 14, 2026. The proposal requires 75% of votes entitled to be cast, and only 72.7% of outstanding shares were present at the meeting.

Key Facts

  • Special meeting reconvened and adjourned on September 15, 2026 due to insufficient votes for the proposal.
  • Proposal requires affirmative vote of holders of at least 75% of votes entitled to be cast in any annual election of directors.
  • 10,760,144 shares (72.7% of 14,806,997 outstanding) were present, constituting a quorum.
  • Meeting will reconvene on October 14, 2026 at 12:00 p.m. ET via live webcast.
  • No changes made to the proposal; record date remains May 28, 2026.
  • Company engaged Sodali & Co. proxy solicitation firm to assist with obtaining quorum.

Financial Impact

No financial impact disclosed; the filing concerns a governance vote that remains pending.

Risk Factors

  • If the proposal fails again, the company retains supermajority voting requirements, potentially impeding future governance changes or strategic transactions.
  • Prolonged inability to secure votes may indicate shareholder dissatisfaction or low engagement.
