AMKOR Technology Inc.'s operating return on assets (operating ROA) has fluctuated over the past five years. The operating ROA was 6.95% in 2023, a decrease from 13.15% in 2022 but still higher than the 9.10% reported in 2020. This indicates that the company's operating efficiency in generating earnings from its assets declined in 2023 compared to the previous year but improved compared to 2020. The company's operating ROA has shown a positive trend overall since 2019 when it was 4.90%, indicating that the company has become more effective in utilizing its assets to generate operating profits over the years. However, the significant decrease from 2022 to 2023 suggests that further analysis is required to understand the factors driving this change in operating performance.
