Weakened CapitalizationSustained negative equity and elevated 2025 leverage constrain financial flexibility and increase insolvency risk under stress. Over the medium term this raises the probability of further financing, potential covenant constraints or dilution, and limits the company’s capacity to self-fund expensive late-stage trials.

This structural cash burn means strategic choices and timelines depend on successful financing or milestones, increasing execution risk and potentially forcing program prioritization or slower platform scale-up.
