What Went Well and What Went Wrong

What Went Well

• Strong liquidity supports an orderly wind-down and distribution: cash & cash equivalents were $271.6M at 3/31/25; management estimates initial distribution of $246.6–$255.4M ($5.13–$5.33 per share) in Q3 2025 and total distribution of $246.6–$259.8M ($5.13–$5.42 per share) pending the vote .
• THB335 Phase 2 readiness by mid-year 2025 maintained; management aims to complete all Phase 2 readiness activities to maximize sale value of the program .
• CEO emphasized decisive capital return strategy: “returning cash to shareholders and selling our assets, including THB335, is the best path forward” (Natalie Holles, CEO) .

What Went Wrong

• Net loss widened YoY: Q1 2025 net loss of $15.8M vs $7.9M in Q1 2024, driven by higher R&D and G&A (including $2.0M restructuring charges) and lower interest income .
• The Board’s adoption of the Plan of Dissolution signals inability to continue as a standalone R&D company; trading cessation and delisting will follow filing of the Certificate of Dissolution pending stockholder approval .
• Organizational disruption: ~50% workforce reduction and halting of all non‑THB335 activities, raising execution risk if the dissolution is not approved and the company must continue operations .

Key Takeaways for Investors

• Event-driven setup: The June 5, 2025 stockholder vote on the Plan of Dissolution and subsequent Certificate filing are the primary near‑term catalysts; initial liquidation distribution targeted for Q3 2025 at $5.13–$5.33 per share .
• Capital return size anchored by current cash and reserves: Total distributions estimated at $5.13–$5.42 per share, excluding any proceeds from sale of assets including THB335; outcome sensitive to reserve requirements and asset sale pricing .
• Operational de‑risking: Phase 2 readiness for THB335 by mid‑year 2025 is intended to enhance sale value; non‑core R&D halted and workforce reduced to conserve cash .
• Financial trajectory: Q1 net loss widened YoY as R&D and G&A increased (including $2.0M restructuring charges); interest income declined with rate changes; cash declined to $271.6M .
• Structural risks: The Board can abandon dissolution; distributions depend on claims resolution and contingency reserves under Delaware law, potentially affecting timing/amounts .
• Trading implications: Expect share price to anchor to per‑share liquidation estimates and timing milestones; additional upside could stem from asset sale proceeds for THB335 if achieved on attractive terms .
• Documentation focus: With no earnings call, rely on 8‑K/10‑Q updates for dissolution progress, distribution sizing and THB335 sale plans; monitor proxy materials and subsequent 8‑K disclosures .
