June 30, 2025 calculation
Operating ROA = Operating income (ttm) ÷ Total assets
= $-28,436,018K ÷ $1,032,690,000K
= -2.75%
The operating return on assets (ROA) of Alpha and Omega Semiconductor Ltd exhibits notable fluctuations over the analyzed period from September 30, 2020, to June 30, 2025. Initially, the company experienced a negative operating ROA of -0.37% as of September 30, 2020, indicating unprofitability or operational inefficiencies at that time. Subsequently, a marked improvement was evident, with the operating ROA turning positive at 1.64% by December 31, 2020, and demonstrating a consistent upward trajectory through the following year, reaching a peak of 8.35% as of December 31, 2021. This trend suggests an operational expansion or efficiency gains during this period.
However, from early 2022 onward, the operating ROA began to decline, decreasing to 8.08% by March 31, 2022, and further down to 6.53% and 5.80% as of June 30 and September 30, 2022, respectively. Continuing this downward movement, the ratio declined below 3% in late 2022 and into early 2023, reaching 1.56% by March 31, 2023, and approximately 1% subsequently.
From the first quarter of 2023 onward, the operating ROA transitioned to negative territory. It declined to 0.49% on September 30, 2023, and then further dropped, registering negative values of -0.34% on December 31, 2023, and -0.33% on June 30, 2024. This negative trend persisted into late 2024 and mid-2025, with the ratio reaching as low as -2.75% by June 30, 2025.
Overall, the data reflects a period of operational growth and profitability between late 2020 and the end of 2021, followed by a gradual decline in operating efficiency and profitability starting in 2022, culminating in sustained negative operating ROA in subsequent periods.
