Aehr Test Systems — FY2022 Form 10-K
Reporting period: Fiscal year ended May 31, 2022. The filing is an annual report, not a standalone fourth-quarter filing; selected unaudited Q4 results are included below. Aehr develops and sells semiconductor test and burn-in equipment, with FY2022 growth concentrated in wafer-level products used for silicon carbide applications.
Financial performance
| Metric | FY2022 | FY2021 |
|---|---|---|
| Net sales | $50.8 million | $16.6 million |
| Gross profit / margin | $23.7 million / 46.6% | $6.0 million / 36.3% |
| Operating income (loss) | $7.8 million | ($4.2 million) |
| Net income (loss) | $9.45 million | ($2.03 million) |
| Diluted EPS | $0.34 | ($0.09) |
| Net cash from (used in) operations | $1.5 million | ($2.7 million) |
- Revenue rose 206%, primarily on wafer-level product sales, which increased to $48.9 million from $15.0 million. Packaged-part sales were $1.9 million.
- Gross margin improved 10.3 percentage points; management attributed the increase mainly to manufacturing efficiencies at higher sales volume.
- FY2022 net income included a $1.698 million gain from forgiveness of the PPP loan. The loan and accrued interest were fully forgiven; operating income was $7.8 million.
- Q4 FY2022 sales were $20.3 million, gross profit $10.5 million, and net income $5.8 million, compared with Q3 sales of $15.3 million and net income of $2.2 million.
Liquidity, debt, and cash flow
- At May 31, 2022, cash and cash equivalents were $31.5 million, working capital $49.0 million, and total shareholders’ equity $51.0 million.
- Operating cash flow was positive $1.5 million, but growth absorbed working capital: accounts receivable increased $7.8 million and inventory $6.7 million. Capital expenditures were $0.4 million.
- Financing provided $25.8 million, including $24.0 million net proceeds from a public offering and $3.6 million from employee stock plans, partly offset by repayment of the $1.4 million line-of-credit balance.
- No amount was drawn on the credit facility at year-end; $8.8 million was available to borrow. The facility’s maturity was January 2023. The PPP loan was forgiven, and no current portion of long-term debt remained.
- Management expected cash, operating receipts, backlog, inventory sales, and customer deposits to cover working capital and capital equipment needs for the next 12 months. This is management’s assessment, not a quantified earnings forecast.
Material changes and business developments
- Revenue rebounded sharply from FY2021, when sales fell 25.5% amid COVID-related disruption. FY2022 wafer-level sales were driven by stronger silicon carbide demand.
- Backlog increased to $11.1 million from $1.6 million year over year. Orders may be rescheduled or canceled, so backlog is not assured future revenue.
- One customer, ON Semiconductor, represented approximately 82% of FY2022 sales; the five largest customers represented 98%. Asia accounted for $45.7 million, about 90% of sales.
- Research and development expense rose 59% to $5.8 million; SG&A increased 53% to $10.0 million, reflecting higher compensation, commissions, and headcount.
- Inventory reached $15.1 million, up from $8.8 million; the company recorded $1.0 million in inventory write-downs. The auditor identified inventory valuation and demand forecasts as a critical audit matter.
- Common shares outstanding increased to 27.1 million from 23.7 million during the year, including shares issued in the public offering and under employee plans.
Outlook, risks, and unusual items
- No specific revenue, earnings, or margin guidance was provided. Management said it would continue investing in priority areas to support long-term profitable growth.
- Key risks include reliance on a small number of customers, lumpy high-value system orders, customer order cancellations or delays, and lengthy customer qualification of FOX systems.
- Supply-chain constraints, limited-source suppliers, component cost inflation, and manufacturing or shipment delays could restrict fulfillment or pressure margins. The company reported $17.6 million of purchase obligations due within 12 months; most purchase orders are cancelable, sometimes with fees.
- Other stated exposures include intense competition and price pressure, semiconductor industry cyclicality, COVID-related disruption, international trade and geopolitical uncertainty, foreign-exchange movements, cybersecurity incidents, and the need to protect intellectual property.
- There were no pending legal proceedings reported and no material off-balance-sheet financing arrangements. Indemnification obligations exist, but their maximum potential amount could not be determined.
Important facts for investors to verify
- Whether silicon carbide demand and customer spending remain strong, and how much of the reported backlog converts to shipments and revenue.
- Customer concentration and collection exposure: three customers comprised 97% of year-end gross receivables, while one customer generated 82% of annual sales.
- Inventory quality and forecast assumptions, including whether the $15.1 million balance can be sold or used without additional write-downs.
- Operating cash conversion as receivables and inventory expand, and liquidity after the public offering proceeds and customer deposits.
- The effect of equity issuance, employee compensation, and potential future financing on per-share results and shareholder dilution.
