FDA regulatory approval risk - PEDD platform represents novel mechanism requiring extensive clinical validation; PMA pathway typically takes 3-5 years with 20-30% historical approval rates for Class III devices
Reimbursement uncertainty - CMS and private payers must establish separate payment codes for PEDD procedures; inadequate reimbursement levels could limit commercial adoption despite clinical efficacy
Clinical trial execution risk - liver cancer trials face enrollment challenges, high dropout rates, and competing standard-of-care options (TACE, systemic therapy, transplant)
Established interventional oncology competitors (Boston Scientific, Terumo, Merit Medical) could develop competing pressure-modulated delivery systems or acquire TLSI's technology
Systemic immunotherapy advances (checkpoint inhibitors, CAR-T) may reduce addressable market for locoregional liver therapies
Alternative hepatic delivery technologies (hepatic artery infusion pumps, Y90 radioembolization improvements) compete for same patient population
Capital runway risk - $20-25M annual burn rate with $60-70M estimated cash (based on 3.05x current ratio) suggests need for financing by Q4 2026 or Q1 2027; dilution risk at depressed valuation
Negative equity position (148.8% ROE with negative earnings indicates negative book value) limits access to traditional debt financing
Going concern risk if clinical milestones slip or FDA requests additional studies requiring capital beyond current runway
