The days of inventory on hand (DOH) for Tandem Diabetes Care Inc have shown an increasing trend over the past two years, from 84.96 days in Q1 2022 to 151.69 days in Q4 2023. This indicates that the company is holding its inventory for longer periods before selling it. A high DOH value could suggest potential issues such as overstocking, slow-moving inventory, or changing customer demand patterns. Tandem Diabetes Care Inc may need to evaluate its inventory management practices to optimize its inventory turnover and ensure efficient liquidity and working capital management.
