The operating profit margin of Alpha and Omega Semiconductor Ltd has exhibited significant fluctuations over the specified period. As of June 30, 2021, the company posted a modest operating profit margin of 1.73%, indicating a relatively narrow margin between revenue and operating expenses. By June 30, 2022, this figure improved substantially to 13.12%, reflecting a notable increase in operational efficiency and profitability during that year.

However, the following year, the margin declined sharply to 3.26% as of June 30, 2023, suggesting a reduction in operational profitability and potential challenges in maintaining prior levels of efficiency. Moving into the fiscal year ending June 30, 2024, the operating profit margin turned negative at -0.57%, indicating an operating loss and possibly increased costs, reduced revenue, or both. This negative trend continued into June 30, 2025, with a further decline to -4.08%, which underscores ongoing operational difficulties and a substantial erosion of profitability.

Overall, the trend demonstrates initial improvement followed by a significant deterioration over the recent years, culminating in consistent operational losses. Such fluctuations highlight the importance of further analysis into the underlying factors affecting operational efficiency and cost management within the company during this period.
