The pretax margin of Alpha and Omega Semiconductor Ltd exhibits significant variability over the observed period. Starting from a negative value of -1.34% as of September 30, 2020, the margin transitioned into positive territory by December 31, 2020, reaching 1.95%. This upward trend continued robustly through the first half of 2021, culminating in a substantial increase to 10.57% as of September 30, 2021. A remarkable surge is observed at the end of 2021, with pretax margins escalating sharply to 65.91%, maintaining a similar high level of 65.55% through March 2022. During this period, the company was operating with very high profitability before experiencing a gradual decline in subsequent quarters, with margins decreasing to approximately 62.23% by September 30, 2022.
From late 2022 onward, the pretax margin demonstrates a marked decline, dropping to 10.78% by December 31, 2022, and continuing downward through 2023, reaching 4.84% in March 2023 and further declining to 2.85% by June 2023. The trend persists into the third quarter of 2023, with margins decreasing to 0.67%, and subsequently turning negative to -0.68% by the end of December 2023. For the first half of 2024, the pretax margin remains negative, with values of 0.09% in March 2024 and -0.40% in June 2024, and further declines observed in subsequent quarters: -2.09% in September 2024, -2.67% in December 2024, and continuing into the subsequent quarters with -2.64% in March 2025 and a significant drop to -14.95% by June 2025. Overall, the data indicates a period of very high profitability during late 2021 and early 2022, followed by a persistent decline into negative territory, suggesting increasing challenges in maintaining pre-tax profitability over the analyzed timeframe.
