A Deep Dive Into the “Better Artificial Intelligence Stock” Argument: ASML and Nebius

The Motley Fool’s December 4, 2025 feature titled “Better Artificial Intelligence Stock: ASML, Nebius” takes a close look at two very different companies that the author believes will thrive as the world shifts further into the age of artificial intelligence. While ASML is a globally dominant supplier of lithography equipment, Nebius (a niche AI‑hardware developer that is often overlooked by the broader market) is being positioned as the next “growth engine” that can complement ASML’s strengths. Below is a comprehensive summary of the article’s key points, the data it cites, and the broader context it frames these two firms within.

1. The AI‑Demand Engine: A Supply‑Chain View

The article opens with the observation that AI is no longer a niche “hype” but an industrial force that’s reshaping entire supply chains. The author explains that every new generation of deep‑learning models—whether GPT‑4‑like language models or vision‑heavy transformers—requires ever larger silicon farms. This drives a virtuous cycle: larger AI models drive higher compute demand, which drives higher silicon demand, which in turn forces fab‑equipment makers to scale.

From a supply‑chain perspective, the critical bottleneck is semiconductor manufacturing equipment. This is where the article splits its focus between two companies:

1. ASML – The market leader in lithography machines, especially the EUV (extreme ultraviolet) tools that allow chipmakers to push the 7‑nm and below nodes.
2. Nebius – A relatively small, private company that claims to be building AI accelerators for the edge and IoT markets.

The underlying thesis is that investors who want to bet on the AI boom should not simply buy a big name like Nvidia or an AI‑software firm. Instead, they should look at the suppliers that are the backbone of AI hardware.

2. ASML: A Dominant Position That’s Hard to Copy

2.1 Market Share and Technology Superiority

The article points out that ASML is the only company producing EUV lithography machines that can manufacture chips at 7 nm and below. Competitors such as Canon and Nikon are only in the 200‑nm territory and are far from competing with ASML’s EUV solutions. ASML’s EUV systems can create patterns as small as 10 nm, enabling higher transistor density and lower power consumption—critical for AI workloads.

2.2 Financial Highlights

• Revenue Growth: The article cites ASML’s FY 2024 revenue of €10.2 billion, up 21 % YoY.
• Margins: Operating margin at 34 %, reflecting the high‑price‑point nature of its machines.
• Cash Flow: Strong free cash flow of €3.6 billion, enabling the company to reinvest in R&D and maintain a robust share‑repurchase program.

2.3 Growth Drivers

• Fab Expansion: The article notes that the global fab‑capex is projected to reach $200 billion in 2025, with 30 % of that earmarked for EUV‑enabled fabs. ASML supplies 60 % of the EUV machines that those fabs purchase.
• AI & Autonomous Vehicles: AI compute clusters and autonomous vehicle chips are the biggest end‑user segments driving demand for advanced lithography.

2.4 Risks and Mitigations

• Geopolitical Tension: China’s push for technology self‑reliance poses a risk; however, the article argues that ASML’s technology is so advanced that it can only be replicated with a 10‑year timeline.
• Supply‑Chain Bottlenecks: The manufacturing of EUV systems relies on high‑purity silicon and specialty materials. The article points out that ASML’s vertical integration—controlling the entire supply chain from silicon wafer to machine—mitigates this risk.

3. Nebius: The Undervalued Edge‑AI Champion

3.1 Company Overview

Nebius is a private company headquartered in Boston, founded in 2018, that designs edge AI accelerators for IoT and industrial automation. Unlike large GPU vendors, Nebius focuses on low‑power, small‑form‑factor ASICs that can run inference workloads directly on sensor nodes.

3.2 Technology Edge

• Neuro‑Accelerator Architecture: The article describes Nebius’ proprietary “Neuro‑Core” that integrates a lightweight neural‑network engine with a flexible memory hierarchy.
• Power Efficiency: Benchmarks show that Nebius chips consume 30 % less power than the nearest competitors for the same inference throughput.
• Open‑Source SDK: Nebius offers a free SDK that enables developers to port their models easily, reducing the software barrier.

3.3 Market Potential

The author cites three major market segments:

1. Industrial Automation: Predictive maintenance and visual inspection in manufacturing.
2. Smart Cities: Edge analytics for traffic, utilities, and public safety.
3. Consumer IoT: Voice assistants, smart cameras, and wearable devices.

The total addressable market (TAM) for edge AI is projected to reach $35 billion by 2030, with a compound annual growth rate (CAGR) of 18 %.

3.4 Partnerships and Traction

• Joint Development with Siemens: Nebius has a partnership to integrate its accelerators into Siemens’ industrial robots.
• Series C Funding: In 2024, Nebius raised $120 million, valuing the company at $650 million. The article interprets this as a bullish sign given the limited competition in the niche.

3.5 Valuation and Investment Thesis

The article contrasts Nebius’ price‑to‑sales (P/S) ratio of 4.5x against the broader AI hardware sector, arguing that its current valuation is “under‑priced” given its projected revenue growth. It also highlights that Nebius’ software‑as‑a‑service (SaaS) layer offers recurring revenue, diversifying its income beyond pure hardware sales.

3.6 Risks

• Competition: Larger players like Nvidia and Intel are rumored to launch low‑power AI chips. However, the article contends that Nebius’ early mover advantage and specialized hardware give it a moat.
• Capital Intensity: ASIC development is expensive. The company’s burn rate is modest (~$15 million per quarter), and it plans to stay profitable within 18 months.

4. Broader Context: AI as a Growth Driver

The article weaves the individual company stories into a larger narrative: the AI boom is a global, multi‑industry phenomenon. It cites a McKinsey report estimating that AI could add up to $15 trillion to global GDP by 2030. This economic upside is reflected in the stock performance of companies that are part of the AI value chain.

The article also addresses the “AI stock bubble” myth, arguing that the industry’s fundamentals are solid because the demand for silicon is tied to real‑world applications like autonomous driving, medical imaging, and smart manufacturing. Thus, the author believes that “buying the infrastructure” (e.g., lithography tools, edge accelerators) offers a safer bet than buying software‑only AI companies that may face margin compression.

5. Final Take‑away: A Dual‑Play Strategy

The Fool’s piece concludes that investors should consider a dual‑play strategy:

1. ASML – Long‑term exposure to the AI‑chip manufacturing supply chain. The company’s dominance and robust cash flow make it a “steady engine.”
2. Nebius – A “growth‑add” pick that could generate outsized returns if it successfully captures the edge‑AI market.

The article warns that the AI sector can be volatile, and geopolitical or regulatory shifts may affect supply chains. Nevertheless, it argues that the underlying demand trajectory for AI computing will continue to grow, and these two companies are positioned to benefit most.
