ACM Research, Inc. — FY2020 Form 10-K
Reporting period: Fiscal year ended December 31, 2020. Although the request identifies “2020 Q4,” this filing reports full-year results, not standalone fourth-quarter results.
Business context
ACM Research develops, manufactures and sells semiconductor manufacturing equipment, principally single-wafer wet-cleaning and other front-end processing tools, with additional advanced-packaging and back-end equipment. Operations are concentrated in China, and substantially all 2020 revenue came from customers in mainland China. ACM Research owned 91.7% of its principal operating subsidiary, ACM Shanghai, at year-end.
Financial performance
| Metric | FY2020 | FY2019 |
|---|---|---|
| Revenue | $156.6 million | $107.5 million |
| Gross profit / margin | $69.6 million / 44.4% | $50.7 million / 47.1% |
| Operating income / margin | $21.5 million / 13.7% | $17.8 million / 16.5% |
| Net income, consolidated | $21.7 million | $19.5 million |
| Net income attributable to ACM Research | $18.8 million | $18.9 million |
| Diluted EPS | $0.89 | $0.99 |
| Cash flow from operations | $(13.5) million | $9.4 million |
Revenue grew 45.7%, led by wet-cleaning and other front-end tools, which generated $136.3 million (87.0% of revenue), up from $90.9 million. Advanced packaging, other back-end tools, services and spares contributed $20.3 million, versus $16.6 million. Gross margin fell 2.7 percentage points, which management attributed primarily to product mix. Operating expenses increased 46.4% to $48.1 million; R&D expense was $19.1 million, or 12.2% of revenue.
Consolidated net income increased, but income attributable to ACM Research was slightly lower as minority shareholders’ share of ACM Shanghai earnings rose. Diluted EPS also declined. FY2020 results included a $12.0 million noncash expense from remeasurement of a financial liability and a $12.6 million unrealized gain on trading securities, substantially offsetting each other before other items and taxes.
Cash, liquidity and debt
At December 31, 2020, cash and cash equivalents were $71.8 million, working capital was $216.8 million, and total assets were $341.3 million. Short-term borrowings were $26.1 million and long-term borrowings were $19.6 million, for total borrowings of approximately $45.7 million. Management said available cash, operating cash flow and short-term bank borrowing were expected to meet anticipated needs for at least 12 months.
Operating cash flow turned negative, primarily amid increased accounts receivable and inventory. Inventory rose to $88.6 million from $44.8 million, and receivables to $56.4 million from $31.1 million. Investing cash outflow was $70.0 million, including $40.2 million prepaid for Lingang housing, $9.7 million for land-use rights, $15.0 million invested in SMIC shares and $5.2 million for property and equipment. The reported non-GAAP free cash flow was $(84.1) million, including these investments. Cash and cash equivalents at year-end were $71.8 million; prior-year cash and restricted cash together were $117.9 million, including $59.6 million restricted for potential redemption of ACM Shanghai private-placement shares, restrictions released in 2020.
Changes, outlook and material developments
- Revenue increased 45.7%; gross margin declined from 47.1% to 44.4%, and operating margin from 16.5% to 13.7%.
- Three customers generated 75.8% of 2020 revenue: the Huali Huahong Group 36.9%, Yangtze Memory Technologies and a subsidiary 26.8%, and SMIC 12.1%. The comparable three-customer concentration was 73.8% in 2019.
- Management expects gross margin of 40%–45% for the foreseeable future and R&D expense of 13%–15% of revenue; it expects sales and marketing, R&D and general and administrative expenses to rise in absolute dollars. The filing provides no specific revenue or earnings forecast.
- ACM expanded existing Shanghai production space by 50,000 square feet in 2020 and began construction of a planned 1-million-square-foot Lingang development and production center, with production targeted to begin in late 2022. The project carries milestone obligations and potential penalties under the land agreement.
- The planned STAR Market listing and IPO of ACM Shanghai remained pending. The listing committee had approved the application in September 2020, then initiated reassessment after an October short-seller report and a December securities class action. Formal registration and CSRC review and approval remained outstanding. ACM proposed offering up to 10% of ACM Shanghai.
- COVID-19 caused a six-day additional closure at ACM Shanghai’s headquarters and delayed some Q1 customer shipments, which were delivered in Q2. The company reported no material supply-chain issue or significant overall negative impact on operations or liquidity through year-end, while warning that future effects remained uncertain.
Risks, contingencies and unusual items
- Customer and market concentration: Dependence on a small group of major Asian customers makes results vulnerable to order timing, cancellations, acceptance delays and semiconductor-cycle downturns.
- Trade and geopolitical exposure: U.S. export restrictions and SMIC’s December 2020 addition to the Entity List could affect customer demand or ACM’s ability to supply. The filing also notes potential requirements concerning ACM Shanghai’s SMIC securities after SMIC’s designation as a “Communist Chinese military company.”
- SMIC investment: ACM Shanghai’s SMIC shares had $28.2 million year-end fair value against $15.0 million cost and were subject to a one-year lock-up. Valuation gains were unrealized; restrictions and the designation create material uncertainty.
- Litigation: A putative securities class action filed December 21, 2020 against ACM and three executives seeks unspecified damages. Management considers the claims without merit, but the company could not estimate likelihood or range of loss.
- Other exposures: The company relies on limited and single-source suppliers, has foreign-exchange exposure without hedging, and depends on PRC operations, subsidies and regulatory conditions. Its auditor is based in China and was not subject to PCAOB inspection, creating potential U.S. listing and audit-oversight risks.
- Reporting and governance: ACM became a large accelerated filer effective year-end. The filing reports unqualified audit opinions on the financial statements and internal controls, and management concluded disclosure controls and internal control over financial reporting were effective.
Most important facts for investors to verify
- Whether reported growth converts into cash: monitor receivables, inventory, customer collections and operating cash flow.
- Whether gross margin stabilizes within management’s 40%–45% outlook, particularly as product mix and manufacturing scale change.
- Whether the company reduces reliance on its three largest customers and expands revenue beyond mainland China.
- Progress, funding and milestone compliance for the Lingang facility and housing commitments, including the impact on liquidity and debt.
- Status and terms of the STAR listing reassessment, securities litigation, and any restrictions or divestiture requirements involving SMIC shares.
- Future earnings excluding volatile non-operating items, including the financial-liability remeasurement, securities gains, foreign-exchange effects and government subsidies.
