The earnings call reveals several challenges: revenue decline due to the end of the Novartis collaboration, cash burn, and significant risks in securing isotope supply, regulatory approvals, and clinical trials. The lack of a shareholder return plan and strategic misalignment with Novartis further weigh on sentiment. Although the cash position is stable, the reliance on external funding and competitive pressures add uncertainty. The Q&A section highlighted management's vague responses, particularly regarding clinical data timelines, adding to the negative sentiment. These factors collectively suggest a negative stock price movement in the short term.
