AMAT vs. ACMR: Which WFE Stock is the Better Buy Right Now?
Read MoreHide Full Article
Key Takeaways
ACMR is positioned as the better buy than AMAT amid AI-driven WFE demand shifts.
ACMR gains from rising chip complexity and cleaning needs, expanding capacity to $3B output.
ACMR's advanced packaging revenues jumped 45% YoY, driven by AI data center demand.
Applied Materials (AMAT - Free Report) and ACM Research (ACMR - Free Report) are two of the most crucial wafer equipment manufacturing (WFE) companies in the world, serving two different verticals. AMAT has the broadest and most diversified offerings as it provides solutions across multiple fabrication steps, like deposition, materials engineering, etch, metrology and packaging. ACMR is a near monopoly in wafer cleaning technology while also providing advanced packaging steps.
Both AMAT and ACMR have become crucial in the AI infrastructure market, bringing investors’ attention to their business models, risk profiles and long-term outlook. Let’s break down how each company is performing and which one looks like the better investment right now.
The Case for AMAT Stock
Applied Materials is a major manufacturer of semiconductor fabrication equipment, covering deposition, etching and inspection, serving the most crucial stages of chip manufacturing. AMAT expects its leading-edge foundry, logic, DRAM and high-bandwidth memory (HBM) to be the fastest-growing wafer fabrication equipment businesses in 2026.
Applied Materials expects its leading-edge foundry, logic, DRAM and HBM to be the fastest-growing wafer fabrication equipment businesses in 2026. In Logic, AMAT’s revenues are driven by the shift from FinFET to Gate-All-Around (GAA) transistors and backside power delivery.
The company specializes in GAA transistors at 2nm and below, HBM stacking and hybrid bonding and 3D device metrology, which are indispensable for manufacturing next-generation semiconductor chips. Recent launches like Xtera epi, Kinex hybrid bonding and PROVision 10 eBeam will add to AMAT’s growth story throughout 2026 and beyond.
AMAT’s DRAM offerings are gaining traction as customers are aggressively investing in 6F² nodes supported by rising demand for high bandwidth memory DRAM, driven by AI workloads. On its first-quarter 2026 earnings call, AMAT highlighted its record growth in both Logic and DRAM segments, driven by major semiconductor transitions.
Applied Materials’ HBM chips are increasing in complexity and size, with three to four times more wafer starts per bit than standard DRAM, making it highly equipment-intensive. This is good for AMAT as the market for HBM expands. Together, these factors will drive the top and bottom lines of AMAT. The Zacks Consensus Estimate for Applied Materials’ fiscal 2026 earnings suggests growth of 18%. The estimates for fiscal 2026 have been revised upward in the past 60 days.

The Case for ACMR Stock
ACM Research is gaining from increased complexity in semiconductor design as layer count and defect sensitivity are increasing the number of cleaning process steps. These factors have given rise to higher demand for high-performance cleaning tools, evident in growing demand for ACMR’s WFE products in Singapore, North America, Korea and Taiwan.
ACMR is trying to match this demand surge through capacity expansion, with Lingang and Oregon now supporting a $3 billion annual output. Furthermore, ACMR has a greater advantage in the market with its proprietary technology, like N2 bubbling technology for 3D NAND, SPM Nozzle design and horizontal plating.
Among these offerings, SPM cleaning is considered to be a high-margin underpenetrated business, supercritical CO2 cleaning that reduces 40% of the cost and other jewels like track systems, PECVD platforms, Panel-level plating tools and expected breakthroughs like ALD, PEALD, LPCVD are a major tailwind for the company.
ACMR’s advanced packaging grew 45% year over year in 2025, driven by increased process intensity and high demand from AI data centers and hyperscalers. These factors are likely to contribute to ACMR’s top line in the upcoming years. The Zacks Consensus Estimate for ACMR’s fiscal 2026 earnings suggests growth of 5.6%. The estimate for fiscal 2026 have been revised upward in the past 30 days.

Conclusion: AMAT vs. ACMR
While Applied Materials remains a high-quality, industry-leading semiconductor equipment company with strong exposure to leading-edge nodes, memory and HBM, ACMR is positioned at the intersection of several powerful structural tailwinds — rising process complexity, increasing cleaning intensity, and the rapid shift toward advanced packaging driven by AI workloads, ensuring multiyear growth. Given these factors, ACMR is a better buy than AMAT at present.
