To evaluate Boston Scientific Corp.'s days of inventory on hand (DOH) over the past eight quarters, we observe a consistent upward trend from Q1 2022 to Q1 2023, with a minor fluctuation in the middle quarters. The company's DOH increased steadily from 167.99 days in Q1 2022 to 208.67 days in Q4 2023, indicating an extended period for the company to convert inventory into sales during the most recent quarter.

This trend suggests potential concerns regarding the management of inventory levels and efficiency in inventory turnover. A higher DOH may imply excess inventory or slow sales, leading to higher storage costs, risk of obsolescence, and reduced liquidity. Although some variability was observed in the middle quarters, the overall rising trend in DOH warrants further investigation to identify potential inefficiencies in inventory management that could impact the company's operational performance and profitability.
