### Risk Assessment

- Foreign exchange risk resulted in a $10.9 million loss in 2025 compared to a $4.2 million gain in 2024, directly impacting the 'Other expense, net' line item. (2 intensifying, 3 easing) (POSITIVE, Risk: MODERATE)
  > Other expense, net primarily reflects (a) unrealized foreign exchange loss recognized from the impact of exchange rates between RMB and U.S. dollar on our working-capital which was $(9.5) million for the three months ended March 31, 2026
- **[CATALYST] Export Rule Change** (NEGATIVE): The risk is intensifying as the company notes that operations, including component imports and U.S. personnel activities, may be further impacted by these designations which prohibit furnishing hardware/software without authorization. (1 intensifying)
  > Our operations in mainland China and Korea... may be further impacted by the addition of ACM Shanghai, ACM Korea and related entities to the BIS Entity List.
- **[METRIC] Gross Margin by Mix** (NEGATIVE, Risk: MODERATE): The risk is easing. Gross margin for Q2 2025 improved to 48.5% from 47.8% in Q2 2024, though the six-month margin (48.2%) remains lower than the prior year (49.6%). (1 easing, 2 intensifying, 1 stable)
  > The decrease in gross margin versus the prior-year period was primarily due to revenue mix between product categories.
- **[METRIC] Inventory Days and Channel Health** (NEGATIVE, Risk: MODERATE): Operating cash flow has deteriorated significantly. For the first six months of 2025, net cash used in operations was $39.6 million, compared to $51.9 million provided in the prior year period, driven by inventory and accounts receivable growth. (3 intensifying, 1 stable)
  > Net cash (used in) provided by operating activities ($29,538) [in 2026] $5,282 [in 2025]
- **[PRINCIPLE] Hyperscaler Concentration Risk** (NEGATIVE, Risk: HIGH): Customer concentration remains high and is intensifying. In Q2 2025, four customers accounted for 66.5% of revenue, compared to 57.9% in the same period in 2024. (3 intensifying, 2 easing, 2 high-severity)
  > Revenue concentration. For the three months ended March 31, 2026 and 2025, three customers accounted for 45.9% and four customers accounted for 53.6% of revenue, respectively.
- **[PRINCIPLE] Chip Cycles Require Supply Discipline** (NEUTRAL): Geographic concentration remains extreme. Substantially all revenue for the first half of 2025 was derived from customers in the People's Republic of China (PRC). (1 stable)
  > During the three and six months ended June 30, 2025 and 2024, substantially all of the Group's revenue were derived from customers with the PRC.
- **[PRINCIPLE] Export Control Exposure** (NEGATIVE, Risk: HIGH): The risk is stable but remains a critical operational hurdle. ACM Shanghai and ACM Korea were added to the BIS Entity List in late 2024, requiring licenses for U.S.-origin technology. (2 stable, 2 intensifying, 3 high-severity)
  > Among the 140 companies added to the BIS Entity List were two subsidiaries of ACM Research, ACM Shanghai, located in the People’s Republic of China, and ACM Korea... the new BIS Entity List designations prohibit any party worldwide from furnishing hardware, software, or technologies that are subject

### Scenario Analysis

- A shift toward lower Fed rates directly reduces the equity discount rate, providing a valuation tailwind for ACMR’s long-duration earnings profile. This first-order change in Treasury yields flows into a second-order acceleration of customer orders, as semiconductor fabricators find it cheaper to finance the massive 'refinancing walls' associated with new plant construction. Ultimately, this triggers a third-order structural shift where ACMR benefits from a sector leadership rotation toward high-growth semiconductor equipment, offsetting the marginal increase in interest expenses from its floating-rate debt facilities. (POSITIVE)
  > Interest income $ 4,719 [in 2026] $ 3,339 [in 2025]... Interest income increased 41.3%... Time deposits held as of March 31, 2026 had interest rates of 1.2% to 3.75%.
- The massive capex expansion by hyperscalers into GPUs and AI servers directly fuels demand for ACM’s ECP and furnace technologies, which are essential for the advanced packaging (like CoWoS) that enables high-performance AI chips. This first-order revenue surge creates a second-order benefit of multi-year backlog visibility and increased R&D capacity for next-generation tools like PECVD. However, this growth is structurally challenged by third-order regulatory shifts, where US-China trade restrictions and outbound investment limits (OISP) threaten to bifurcate the company's capital structure and supply chain, forcing a strategic pivot toward domestic US manufacturing in Oregon. (POSITIVE)
  > Effective on December 2, 2024, the U.S. Department of Commerce’s Bureau of Industry and Security (“BIS”) promulgated a final rule naming a number of companies to the BIS Entity List... Among the 140 companies added to the BIS Entity List were two subsidiaries of ACM Research, ACM Shanghai... and ACM
- The imposition of U.S. export controls on ACM's core subsidiaries acts as a primary first-order shock, severing access to critical U.S. technology and hardware. This triggers a second-order paradox where Chinese customers front-load orders to localize supply chains, temporarily boosting revenue while simultaneously trapping the company's assets in a restricted jurisdiction. Ultimately, this leads to a third-order structural valuation discount as the company becomes a 'stranded asset' in the eyes of U.S. investors, burdened by higher tax rates and restricted capital flows under the COINS Act. (NEGATIVE)
  > Effective on December 2, 2024, the U.S. Department of Commerce’s Bureau of Industry and Security (“BIS”) promulgated a final rule naming a number of companies to the BIS Entity List... Among the 140 companies added to the BIS Entity List were two subsidiaries of ACM Research, ACM Shanghai... and ACM
