UBS Reinforces a Constructive View on China Semiconductor Equipment, Raising 2027-28 WFE Spending and Target Prices for Three Leaders

Overview

This UBS report on China semiconductor equipment focuses on 2026-28E China fab equipment spending, memory capex, localization of equipment, and the earnings and valuation of three leading Chinese WFE players. The report argues that, although the related stocks have already rallied sharply year to date, the medium-term earnings growth of NAURA, AMEC and ACMR Shanghai is still not fully reflected, supported by a more durable memory upcycle, faster localization, rising domestic vendor share, and advanced logic demand.

Core views

The key views are: first, visibility for China WFE spending growth in 2027-28 has improved, mainly due to the expanded memory capex capacity that follows the significant improvement in profitability and cash flow at CXMT and YMTC. Second, DRAM equipment localization is likely to accelerate from 2026, helping domestic equipment makers win higher order share. Third, the positive demand and order commentary from NAURA and AMEC, the solid 1Q26 performance of major WFE companies, and breakthroughs in high-end equipment all support earnings upgrades. Fourth, although valuations have already moved higher, the three covered names still trade at a discount to domestic WFE peers, and UBS believes stronger growth should justify higher target P/E multiples.

Analysis framework

The report uses a combined top-down and bottom-up approach: it first updates forecasts for total China WFE spending, memory WFE spending and logic WFE spending, then incorporates capex plans at key customers such as CXMT and YMTC, supply-chain feedback, changes in localization rates, and each equipment vendor's product mix to derive revenue, EPS, gross margin and target P/E multiples for NAURA, AMEC and ACMR Shanghai. The valuation method is mainly the P/E multiple method.

Methodology notes

• Valuation methodsPE multiple valuation

  P/E multiple valuation

  UBS values AMEC, NAURA and ACMR Shanghai using 2027E P/E multiples, and raises target multiples on the back of higher EPS CAGR, faster localization and upward re-rating across peers.

• Industry forecastWFE spending forecast

  WFE spending forecast

  The report updates 2026-28E China WFE spending forecasts based on domestic memory and logic fab expansion, customer cash flow, supply-chain feedback and localization assumptions.

• Earnings forecastEPS revision

  EPS revision

  UBS raises 2027/28E EPS for the three covered companies on assumptions of higher revenue, stable or improving gross margins, R&D efficiency and operating leverage.

• Theme analysislocalisation and share gain

  Localization and share gains

  The report treats localization of DRAM, NAND and advanced logic equipment as a long-term structural driver, with a focus on share gain opportunities for each company in etch, deposition, cleaning and advanced packaging.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• NAURA

  A leading Chinese WFE vendor and one of the report's key Buy ideas

  Strengths

  Leading domestic revenue scale, coverage of etch, PVD and cleaning, high exposure to advanced logic and DRAM customers, and a breakthrough in CCP etch at NAND customers. UBS expects WFE revenue CAGR above 40% in 2026-28E.

  Weaknesses

  Ramp-up of new products may bring debugging costs, and digestion of mature-node demand may offset some growth.

  Comparison

  The report believes NAURA trades at a discount to domestic WFE peers, but its earnings growth outlook is stronger; the market underestimates its wallet share in 3D NAND, memory expansion and advanced logic.

  Risks

  Geopolitical restrictions widen, China WFE demand is weaker than expected, and intensifying competition in etch, deposition and cleaning leads to share loss.

• AMEC

  One of China's key WFE suppliers and technology leaders

  Strengths

  Has technical advantages in plasma etch and deposition, benefits from China WFE expansion and localization; its 90:1 high-aspect-ratio CCP etch tool at NAND customers could expand SAM upon certification. UBS expects revenue CAGR of 46% in 2026-28E.

  Weaknesses

  High R&D spending may pressure profits in the near term, and product-line expansion requires continued investment.

  Comparison

  The report also believes AMEC trades at a discount, but its earnings growth in NAND, DRAM and advanced logic expansion is underestimated.

  Risks

  Geopolitical restrictions, weaker-than-expected China WFE demand, intensifying competition for etch share, longer-than-expected development cycles for new products, and loss of key management or R&D leaders.

• ACMR Shanghai

  A cleaning-equipment leader and a beneficiary of localization

  Strengths

  High-end cleaning equipment has passed qualification with domestic customers; SPM has started shipping and is ramping, while PECVD, track, ECP and advanced packaging-related demand provide growth opportunities. UBS expects revenue CAGR of around 30-40% over the next two to three years.

  Weaknesses

  Cleaning equipment has relatively low barriers to entry, competition is more intense, and growth is slightly lower than NAURA and AMEC.

  Comparison

  The report says ACMR Shanghai trades at a discount to domestic WFE peers, and the market has not fully priced in its competitiveness in cleaning and advanced packaging equipment.

  Risks

  Geopolitical restrictions, weaker-than-expected China WFE demand, share loss due to competition in the cleaning equipment market, and longer-than-expected new product development cycles.

• China WFE equipment vendors overall

  An industry asset group benefiting from domestic fab expansion and equipment localization

  Strengths

  Improved visibility on CXMT and YMTC capex, faster DRAM localization, advanced logic expansion and upstream equipment localization are all expanding demand.

  Weaknesses

  The industry remains affected by the semiconductor cycle, export controls and customer capex timing.

  Comparison

  Compared with overseas WFE peers, Chinese equipment vendors are expected to deliver higher earnings CAGR, but some valuations still remain below what their growth outlook would imply.

  Risks

  Weaker macro and end-market demand, escalating geopolitics, a downturn that lasts longer than expected, Chinese fabs pausing projects or cutting capex, and slower-than-expected R&D progress.

Impact & implications

If UBS is right, the investment thesis for China semiconductor equipment will extend from near-term earnings leverage to medium-term visibility on 2027-28 memory and advanced logic expansion, while higher localization could enlarge the revenue pool and valuation tolerance for domestic leaders. For investors, the key issue is not only 2026 growth, but also whether capex continues to be delivered after DRAM and NAND customers improve cash flow, and whether domestic equipment vendors can win meaningful share in high-end etch, deposition, cleaning and advanced packaging.

Risks

• Macro conditions and end-market demand are weaker than expected, reducing semiconductor equipment demand.
• Geopolitical tensions intensify, and export controls or restricted scopes expand.
• The semiconductor downcycle lasts longer than expected.
• Chinese fab projects are paused or capex comes in below UBS estimates.
• Domestic equipment vendors' R&D progress is slower than expected, affecting the introduction of high-end tools and share gains.
• Competition intensifies in etch, deposition and cleaning sub-segments, which may pressure market share or gross margins.
• New product development, customer qualification and mass-production ramp-up take longer than expected.

What to watch

• Whether revenue, profitability, operating cash flow and capex plans at CXMT and YMTC continue to improve.
• Whether the DRAM and NAND upcycles continue until around UBS's assumed 2Q28 and 4Q27, respectively.
• Whether domestic memory expansion in 2026-28E stays close to the roughly 120k/200k wpm range and the further upside implied for 2028.
• Whether DRAM equipment localization accelerates from 2026 and drives higher order share for domestic vendors.
• Changes in NAURA's share in high-end CCP etch, advanced logic and DRAM customers.
• Order conversion for AMEC's high-aspect-ratio CCP etch tool after NAND customer qualification.
• The pace of revenue ramp-up for ACMR Shanghai's high-end SPM, PECVD, track and ECP equipment.
• Whether gross margins for Chinese WFE companies can stabilize in 2026 and continue to improve as product mix improves.
• The impact of geopolitical restrictions, export controls and supply-chain feedback on domestic fab expansion timing.
