AMKOR Technology Inc.'s operating return on assets (operating ROA) has shown a fluctuating trend over the past eight quarters. The operating ROA decreased from 13.32% in Q1 2022 to 6.95% in Q4 2023. This decline indicates a decrease in the company's ability to generate operating income relative to its total assets over this period.

The highest operating ROA was observed in Q2 2023 at 10.39%, suggesting a temporary improvement in the company's operating efficiency and profitability. However, this was followed by a decrease in the subsequent quarters.

The overall downward trend in operating ROA from Q1 2022 to Q4 2023 could be a cause for concern, as it indicates a potential decline in the company's operational profitability and productivity. Further analysis of the company's financial performance and operational efficiency may be required to understand the factors contributing to these fluctuations in operating ROA.
