Biogen Inc's return on assets (ROA) has shown fluctuations over the past eight quarters. In Q1 2022, the ROA was 6.14%, which increased to 8.21% in Q2 2022. The ROA further improved in Q3 2022 to 11.53% and reached its peak in Q4 2022 at 12.41%. However, in Q1 2023, there was a significant decrease in ROA to 12.73%, followed by a further decline to 10.59% in Q2 2023 and 5.18% in Q3 2023. In the most recent quarter, Q4 2023, Biogen Inc's ROA stands at 4.33%.

Overall, the trend indicates a general downward trajectory in ROA since Q4 2022, with a sharp decline from Q3 2023 to Q4 2023. This declining trend may suggest potential inefficiencies in asset utilization or declining profitability relative to the company's asset base. Further analysis of the company's financial performance and underlying factors affecting ROA would be necessary to identify the specific reasons for the observed fluctuations.
