Hwatsing Technology: A Real CMP Champion, Priced as if the Platform Story Is Already Won

Hwatsing Technology (688120.SHG) is China's domestic leader in chemical-mechanical-polishing equipment, expanding from a single CMP tool into a broader semiconductor-equipment and services platform. 2025 revenue grew 36.5% to CNY 4.65 billion and net profit rose to CNY 1.08 billion, but operating cash flow fell 30.7% as inventory and receivables absorbed cash, even as the stock trades near 120.6x trailing earnings around the 99th percentile of its own valuation history. Rating Avoid: the CMP franchise and platform ambition are real, but the price already assumes a platform future the segment disclosures cannot yet prove, with the ideal buy zone at CNY 110 to 125.

ACM Research Shanghai: A Genuine Platform Story, Priced for Zero Margin of Safety

ACM Research Shanghai is the Shanghai-listed operating core of a dual-listed Chinese semiconductor wet-process equipment group, whose U.S. parent ACM Research (ACMR.US) holds a 73.6% stake but trades at a steep discount to the A-share line's implied look-through value. 2025 revenue rose 20.8% to CNY 6.79 billion and net profit rose 21.1% to CNY 1.40 billion, but operating cash flow collapsed to just CNY 239 million from CNY 1.22 billion and turned negative in the first quarter of 2026, even as the stock trades near 130 times trailing earnings and about 180% above the parent-implied look-through value. Rating Watch: the platform story is real, but the price already assumes near-flawless execution while cash conversion has weakened, with the ideal buy zone at CNY 140 to 150.

KINGSEMI: A Scarce Domestic Track Asset, Priced Well Ahead of the Evidence

KINGSEMI is a specialized Chinese semiconductor-equipment maker in front-end coat/develop tracks and single-wafer wet tools, now controlled by NAURA. 2025 revenue grew 11% to CNY 1.95 billion, but attributable profit fell 65% to CNY 71.7 million, and a one-month 79% surge lifted the market cap to CNY 88.5 billion, about 45 times sales. Rating Avoid: a genuinely scarce front-end track franchise, but at CNY 439 the price already assumes a mature cleaning-and-platform business the operating evidence does not yet support.

Beijing Jingyi: A Genuine Semiconductor Subsystem Business at an Increasingly Demanding Price

ACM Research: A Credible China Semicap Franchise, a Demanding Holdco Structure

ACM Research is a Nasdaq-listed holding company whose value is dominated by its roughly 73.6%-owned, Shanghai-listed subsidiary ACM Shanghai, built on a single-wafer wet-cleaning franchise now broadening into plating, furnace, track and PECVD. The parent trades at a steep discount to the quoted value of that stake, yet the A-share quote is already rich, four customers make up 52.2% of 2025 revenue, and first-quarter 2026 free cash flow was negative 52.1 million USD. Rating Hold: strong China semicap execution is real, but at 104.50 USD the price offers too little protection against cash-conversion, policy and holdco-structure risk.

NAURA Technology Group SUN-R Investment Analysis

NAURA is China's broadest listed domestic wafer-fab equipment platform, selling into etch, deposition, cleaning and more, with 2025 process-equipment revenue of CNY 36.73 billion. Real usage clearly carries the story, with two tool families each topping CNY 10 billion in 2025, yet at roughly 48x forward earnings the stock already discounts years of near-flawless execution. Rating Watch: a genuine national champion worth owning on pullbacks into the CNY 500-580 fair-buy band, not chasing because the localization story is true.
