Shelf registration — potential dilution
Actionable Insight ▼ Bearish

The S-3 registration converts warrant overhang into freely tradable shares. Monitor for stockholder approval (needed for warrant exercisability) and any subsequent selling by Sabby, the dominant holder. The company's going-concern status and need for capital suggest additional future dilution is likely beyond this registration.

Executive Summary

Tempest Therapeutics filed an S-3 registration statement to register 2,426,897 shares of common stock for resale by selling stockholders, consisting of shares underlying New Warrants (2,344,828 shares at $1.73 exercise price) and Placement Agent Warrants (82,069 shares at $2.1625 exercise price) issued in a May 28, 2026 warrant inducement transaction. The company will not receive proceeds from share resales but could receive up to ~$4.23M if all warrants are exercised for cash; however, the registration enables near-term overhang from up to 2.4M potential shares entering the market, representing ~15% dilution on the current 15.98M outstanding shares.

Key Financial Metrics

Dilution
15.2%

Key Facts

  • S-3 registers up to 2,426,897 shares for resale by selling stockholders, primarily Sabby Volatility Warrant Master Fund (2,344,828 shares of New Warrants).
  • New Warrants have $1.73 exercise price, become exercisable upon stockholder approval, expire May 29, 2028; Placement Agent Warrants at $2.1625.
  • Company received ~$2.03M cash from exercise of Existing Warrants at $1.73 on 1,172,414 shares on May 28, 2026.
  • If all Warrants exercised for cash, gross proceeds to company would be ~$4.23M for working capital.
  • Maximum share count would increase from 15,979,411 to 18,406,308 — dilution of ~15.2%.
  • Last closing price $1.05 on June 25, 2026; market cap ~$18M.
  • Auditor Ernst & Young included going-concern qualification in 10-K for year ended Dec 31, 2025.
  • 10-Q shows accumulated deficit and need for additional capital to fund operations.

Financial Impact

Potential ~$4.23M cash proceeds if all warrants exercised; registration alone creates ~15% share overhang risk on $18M market cap.

dilutionshare count

Risk Factors

  • Near-term selling pressure from resale registration of up to 2.4M shares (~15% of outstanding).
  • Going-concern qualification in 10-K indicates high risk of further dilutive financing.
  • Warrant exercises depend on stockholder approval and market price above $1.73/$2.1625.
