Shattuck Labs meldete eine Privatplatzierung am 25.08.2025, bei der akkreditierte Investoren unter Führung von OrbiMed-Fahrzeugen insgesamt 6.306.127 Stammaktien erwarben und vorrangig finanzierte Warrants zum Kauf von bis zu 12.133.661 Aktien sowie zusätzliche Stammwarrants zum Erwerb von bis zu 18.439.799 Aktien erhielten. Der Preis pro Aktie mit begleitendem Stammwarrant betrug $0,8677; der Preis des vorrangig finanzierten Warrants mit begleitendem Stammwarrant betrug $0,8676. Vorrangig finanzierte Warrants sind sofort ausübbar, unterliegen jedoch einer 9,99% Sperre des wirtschaftlichen Eigentums. Der Bericht wurde von Mona Ashiya eingereicht, die als Direktorin bezeichnet ist und das wirtschaftliche Eigentum an den Wertpapieren außer im Rahmen eines pecuniären Interesses bestreitet; die Wertpapiere sind auf OrbiMed-Fonds und zugehörige Einheiten eingetragen.

Positive
  • Material capital raise: Issuer sold shares and warrants to accredited investors, providing immediate funding.
  • Pre-funded warrants allow investors to limit immediate dilution until exercised.
  • Detailed disclosure of entity relationships and beneficial ownership disclaimers enhances transparency.
Negative
  • Potential dilution: Warrants could convert into a large number of shares (up to 18,439,799), creating future overhang.
  • Low unit price: Pricing at ~$0.8677 per share/unit may reflect downward pressure on equity valuation.
  • Immediate exercisability of pre-funded warrants (subject to blocker) could lead to concentrated ownership changes if exercised.

Insights

TL;DR: Company raised capital via a private placement led by OrbiMed, creating significant warrant overhang but providing immediate cash at sub-$1 pricing.

The private placement injected cash into the company through sale of common shares and a mix of pre-funded warrants and common warrants. Aggregate figures are material relative to typical micro/small-cap financings: 6.3 million shares plus pre-funded warrants for 12.1 million shares and warrants for 18.4 million shares, priced at about $0.87 per unit. The pre-funded warrants reduce immediate dilution until exercised but are exercisable now subject to a 9.99% blocker. The multi-party ownership structure and disclaimers indicate that OrbiMed-affiliated entities hold record title while investment and voting power is routed through OrbiMed Advisors. This transaction likely improves near-term liquidity while creating a meaningful potential share overhang contingent on future warrant exercises.

TL;DR: Reporting shows standard institutional placement mechanics with customary manager disclosures and beneficial ownership disclaimers.

The Form 4 discloses that record ownership rests with OrbiMed funds and that OrbiMed Advisors, GP entities, and a management committee may be deemed to have voting and investment power, while each party disclaims beneficial ownership except for pecuniary interest. Mona Ashiya is identified as a director filing the Form 4, and the filing includes the required signature and explanatory footnotes clarifying relationships among OrbiMed entities. From a governance perspective, disclosures align with Rule 16 reporting practices and clarify chain-of-control without asserting direct beneficial ownership by the director.
