Executive Summary

Shattuck Labs is conducting a $75M underwritten public offering of 10.9M common shares and 7.9M pre-funded warrants at $4.00/share, a ~6.3% discount to the $4.27 prior close. The company simultaneously disclosed that ~96% of warrants from its August 2025 PIPE have been exercised, generating ~$54.9M in gross proceeds, extending cash runway into 2029. The offering adds ~$70.5M net proceeds, but immediate dilution to new investors is $2.08/share (52% of offering price).

Actionable Insight

The dilutive offering at a discount to market price creates near-term selling pressure, but the extended cash runway into 2029 removes financing overhang for a pre-revenue biotech. Monitor for the underwriters' greenshoe exercise and any insider participation. The Phase 1 SL-325 data provides a positive catalyst backdrop, but the primary endpoint readout from the Phase 2b RECEPTIVE-CD1 trial is not expected until H1 2028 — a long wait with no near-term catalysts.

Key Facts

  • Offering of 10,879,376 common shares and 7,870,624 pre-funded warrants at $4.00 per share, raising $75M gross / $70.5M net
  • Offering price represents a ~6.3% discount to the $4.27 prior close on June 9, 2026
  • Immediate dilution of $2.08 per share (52% of offering price) for new investors
  • Pro forma net tangible book value per share after offering: $1.92 (vs. $1.27 pre-offering)
  • Underwriters have 30-day option for an additional 2,812,500 shares
  • Concurrent warrant exercises: ~50.6M common stock warrants exercised (96% of Aug 2025 PIPE), generating ~$54.9M gross proceeds
  • Cash runway extended into 2029, per company guidance (including warrant exercise proceeds)
  • Pre-funded warrants have nominal $0.0001 exercise price, no public trading market expected
  • Positive Phase 1 SL-325 data announced June 8, 2026 — no serious AEs, complete DR3 occupancy at all doses, quarterly dosing potential

Financial Impact

$75M gross / $70.5M net proceeds from offering; $54.9M from warrant exercises; combined cash ~$215M pro forma (est.)

Risk Factors

  • Immediate 52% dilution per share for new investors
  • No public market for pre-funded warrants limits liquidity for those holders
  • Massive warrant overhang: 47.5M common warrants and 38.4M pre-funded warrants outstanding as of March 31, 2026
  • Pre-revenue biotech with no approved products; Phase 2b data not expected until H1 2028
  • Stock price volatility typical for clinical-stage biotech; potential for further dilutive offerings
