To analyze Biogen Inc's days of sales outstanding (DSO) over the past eight quarters, we calculate the average DSO for the company during the period. The DSO represents the average number of days it takes for the company to collect payments from its customers after making a sale.

The average DSO for Biogen Inc over the mentioned period is 73.04 days. We observe a slight fluctuation in DSO over the quarters, ranging from 68.19 days in Q1 2022 to 80.71 days in Q3 2023. Generally, a lower DSO indicates a faster collection of accounts receivable, while a higher DSO suggests slower collections.
