Revenue grew 41.3%; management attributed growth to higher shipments and a favorable product mix, including a 143.7% increase in power IC revenue. Unit shipments rose 23.0%, while average selling price increased 14.5% due to mix. Gross margin improved by 9.0 percentage points, with higher JV capacity utilization cited as a contributor. R&D expense increased 22.8% to $63.0 million; SG&A rose 19.6% to $77.5 million.
At June 30, 2021, cash and cash equivalents were $202.4 million, working capital was $174.1 million, total assets were $918.6 million, and total liabilities were $402.2 million. Consolidated bank borrowings were $136.0 million and finance lease liabilities were $29.4 million. The JV’s debt is included in the consolidated reporting; it is owed by the separate JV entity, and AOSL states it does not guarantee that debt or have direct access to its loan proceeds. Cash, cash equivalents and restricted cash totaled $204.8 million. Operating cash flow was strong, while capital spending included $72.7 million of property and equipment purchases.
Changes, outlook and material risks
- Quarterly momentum: FY2021 revenue increased each quarter, from $151.6 million in September 2020 to $177.3 million in June 2021. June-quarter net income attributable to AOSL was $19.5 million.
- Capacity and investment: The Chongqing JV reached targeted assembly and test production and was expected to ramp its Phase I 12-inch wafer-fab target run rate in the quarter ending September 30, 2021. AOSL began plans to expand and upgrade its Oregon fab; after year-end, its subsidiary entered into a loan agreement for up to $45 million for that purpose.
- Management outlook: AOSL said existing cash and operating cash flows should cover anticipated needs, including working capital and capital expenditures, for at least 12 months. It did not provide specific revenue or earnings guidance in the filing. It expects margins to remain sensitive to product mix, utilization, JV ramp costs, input costs and market conditions.
- Market and concentration exposure: PC applications represented 42.5% of FY2021 revenue. Two distributors accounted for 64.1% of revenue. Demand, seasonality and distributor inventory changes may cause substantial quarterly fluctuations.
- Export-control matter: The DOJ investigation into export-control compliance involving Huawei remained pending; AOSL had not shipped to Huawei since December 31, 2019. The company could not estimate a reasonably possible loss or range of loss. A related shareholder class action was also pending, and AOSL said it intended to defend it.
- Other significant risks: COVID-19-related demand and supply-chain uncertainty, semiconductor capacity constraints, U.S.-China tensions and export rules, JV financing and ramp execution, product pricing pressure, and restrictions on moving funds from China. Approximately $209.9 million, or 50.4% of consolidated net assets attributable to AOSL, was described as restricted in China.
- Commitments and audit: Contractual obligations totaled $384.1 million, including $90.0 million of capital commitments and $81.8 million of purchase commitments. The auditor gave an unqualified opinion on the financial statements and internal controls; inventory valuation was identified as a critical audit matter.
