Based on the operating return on assets (operating ROA) data for Regeneron Pharmaceuticals, Inc. over the past eight quarters, there is a clear trend of decreasing operating ROA over time. The operating ROA has shown a steady decline from 34.52% in Q1 2022 to 12.79% in Q4 2023.

This decreasing trend in operating ROA may indicate that the company's operating income generated per dollar of assets has been declining over time. Factors such as increasing operating expenses, lower revenue growth, or inefficiencies in asset utilization could be contributing to this decline in operating ROA.
