Tempest reported $822,000 of stockholders' equity against Nasdaq's $2,500,000 minimum, and two director resignations leave it short of several board rules. Its 10-K already carried a going-concern warning.
Tempest sold 405,000 shares and prefunded warrants for 334,000 shares to one institutional investor at $6.25 each, for about $4.1 million net. The company's cash estimate runs only into the second quarter of 2026, and it is exploring strategic alternatives.
Nasdaq sent the company a formal notice of compliance on April 24, 2025. The 8-K does not say how the price was restored, and the lead drug's Phase 3 timeline is subject to funding.
Tempest Therapeutics will cut 21 of its 26 full-time employees as it explores strategic alternatives, with cuts effective April 30, 2025. It expects about $1.5 million in cash costs, mostly severance, and its 2024 10-K said cash of $30.3 million would last at least 12 months.
Latest balance sheet, Jun 30, 2026 (10-Q): cash and equivalents $779,000.
