TPST does not currently have enough recent insider (Form 4) trading activity to compute a convergence signal against its 13F institutional flows.
13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

View Full Filing (SEC EDGAR)On September 11, 2026, Tempest Therapeutics (TPST) signed a securities purchase agreement with an institutional investor for a private placement worth roughly $2.5 million in gross proceeds. The deal packages pre-funded warrants (exercisable at just $0.001/share) alongside Series C and Series D warrants — each covering up to about 3.1 million shares — with a combined price of $0.804 per unit. If the Series C and D warrants are fully exercised later, the company could pull in up to an additional $5 million, though that requires stockholder approval within 90 days. H.C. Wainwright served as placement agent, earning a 7% cash fee plus warrants to buy roughly 217,000 shares at $1.0063 each.
