The earnings call highlights several challenges: reduced revenue guidance, logistical delays, and increased expenses. Despite positive developments like new customer onboarding and potential Medicare reimbursement, the lowered guidance and uncertainties in timelines overshadow the positives. The Q&A session reveals cautious management responses and possible revenue delays into Q1. These factors, combined with increased cash usage and reduced gross margin projections, suggest a negative market reaction in the short term, likely leading to a stock price decline of -2% to -8%.
