ASML Holding N.V. (Ticker: ASML) is a critical player in the technology world, enabling the creation of the advanced microchips that power everything from smartphones to artificial intelligence.

1. The Business Model (How They Make Money)

ASML's core business revolves around designing and manufacturing highly sophisticated machines called photolithography systems, often referred to as "scanners." These machines are essential for semiconductor manufacturers to print incredibly tiny, intricate patterns onto silicon wafers, which are then turned into integrated circuits or microchips. ASML holds a unique position as the world's only supplier of Extreme Ultraviolet (EUV) lithography machines, which are necessary for producing the most advanced chips.

ASML generates its money primarily through two main avenues:

• Selling Advanced Lithography Systems: This is the largest part of their business. They sell various types of lithography systems, including EUV and Deep Ultraviolet (DUV) systems, as well as metrology and inspection tools. These machines are incredibly complex and expensive, representing a significant investment for chipmakers like Intel, Samsung, and TSMC. In 2025, ASML's total net sales were €32.7 billion. Of this, EUV system sales alone accounted for €11.6 billion. For the first quarter of 2026, total net sales were €8.8 billion, with system sales reaching approximately €6.3 billion. In the second quarter of 2026, total net sales were €9.3 billion, with net system sales contributing €6.6 billion.
• Installed Base Management (Services and Upgrades): Beyond the initial sale, ASML provides ongoing services, maintenance, and upgrades for the machines already installed at customer factories. This creates a recurring revenue stream, much like how a printer company sells ink cartridges after selling the printer. This "razor and razorblade" approach ensures continued revenue as chipmakers rely on ASML to keep their equipment running efficiently and up-to-date. In 2025, net service and field option sales increased by 26.2% compared to 2024, reaching €8.2 billion. In the first quarter of 2026, Installed Base Management revenue was approximately €2.5 billion, and in the second quarter of 2026, it was €2.8 billion.

The demand for ASML's equipment is currently being significantly boosted by the rapid growth in artificial intelligence (AI), which requires more advanced and powerful chips. ASML anticipates its total net sales for the full year 2026 to be between €43 billion and €45 billion.

2. The Metrics That Matter Most

For ASML, a company at the forefront of semiconductor technology, these metrics are particularly insightful:

• Revenue: This is the total amount of money ASML brings in from selling its lithography systems and providing services. For ASML, revenue is crucial because it directly reflects the demand for their highly specialized and essential equipment. Strong revenue growth indicates that chip manufacturers are investing heavily in new production capabilities, often driven by the need for more advanced chips for things like AI. ASML reported total net sales of €32.7 billion in 2025.
• Net Income: This metric shows how much profit ASML actually keeps after covering all its costs, including manufacturing, research, sales, and taxes. For a company with high fixed costs and significant investments, net income demonstrates its overall financial health and efficiency in turning sales into profit. In 2025, ASML's net income was €9.6 billion.
• R&D Expenses (Research & Development Expenses): ASML's competitive edge comes from its continuous innovation in lithography technology. R&D expenses represent the money ASML pours back into developing next-generation machines and improving existing ones. High and consistent R&D spending is vital for ASML to maintain its technological leadership and ensure future revenue streams in a rapidly evolving industry. In 2025, ASML's R&D costs totaled €4.7 billion.
• Gross Margin: This tells you the profit ASML makes from each sale after subtracting the direct costs of making the product or providing the service, but before accounting for operating expenses like R&D or sales. For ASML, a high gross margin (52.8% in 2025 and 54.0% in Q2 2026) indicates strong pricing power for its unique and indispensable technology, as well as efficient manufacturing processes for its complex systems.
• Operating Cash Flow: This metric shows the cash generated from ASML's regular business activities before accounting for investments or financing. For a company that requires substantial capital to build its advanced machines and fund its extensive R&D, a healthy operating cash flow is essential. It ensures ASML has enough cash from its core operations to fund its growth, pay its suppliers, and potentially return money to shareholders, without having to borrow excessively.

3. How to Value This Company

The most relevant valuation metric for ASML is the P/E Ratio (Price-to-Earnings Ratio).

The P/E ratio compares ASML's current stock price to its earnings per share. It helps you understand how much investors are willing to pay for each dollar of ASML's profit. For a company like ASML, which is a market leader with a strong growth trajectory and a near-monopoly in critical technology, the P/E ratio is a widely used tool to gauge its value.

Why it matters for ASML: ASML's unique position and its role in enabling the entire semiconductor industry mean it often commands a premium valuation. By looking at the P/E ratio, you can see if the market is valuing ASML's future growth potential appropriately. If the P/E ratio is significantly higher than its historical average or that of similar high-growth technology companies, it might suggest the stock is considered "expensive," meaning investors are paying a lot for its expected future earnings. Conversely, a lower P/E could suggest it's "cheap" relative to its earnings power. As of September 30, 2026, ASML's trailing twelve months (TTM) P/E ratio was 58.13x, which is higher than its five-year median P/E of 39.25x. This indicates that the market has high expectations for ASML's future earnings growth.
