Because TSMC is the world's leading manufacturer of advanced AI chips and ASML's largest foundry customer, its revenue trajectory is a leading indicator for lithography equipment orders. ASML opened up 3.14% on August 11 and held those gains through the close as investors priced in continued capacity expansion from the foundry giant .

2. Second Guidance Raise in 2026

The company's own financial trajectory has been equally compelling. ASML reported Q2 2026 net sales of €9.33 billion — beating consensus estimates of roughly €8.8 billion — and net income of €2.92 billion . Gross margin improved to 54.0% from 53.0% in the prior quarter as the company sold 86 new lithography systems, up from 67 in Q1 .

More importantly, management raised full-year 2026 guidance for the second time. The new outlook calls for net sales of €43–€45 billion with a gross margin of 54–56%, up sharply from the €34–€39 billion range set at the start of the year . CEO Christophe Fouquet described first-half orders as "extremely strong," with customers racing to expand capacity for AI chip production .

3. Analyst Upgrades: Goldman Sachs and Bernstein

On August 4 — a week before the TSMC-driven rally — Goldman Sachs added ASML to its European Conviction List, while Bernstein simultaneously named it a top pick for Q3 2026 . The double endorsement triggered institutional buying that pushed the stock up 4.3% that day alone .

Bernstein set a Street-high price target of $2,623, implying roughly 50% upside from August 10 levels . The consensus across 44 analysts sits at an average target of $2,178.04, about 25% above the stock's price in early August . Bank of America had already lifted its target to $2,345 in late June, while Wells Fargo raised its to $2,200 .

4. Structural EUV Monopoly

Underpinning every bullish thesis is a fact that no competitor can replicate: ASML is the world's sole producer of extreme ultraviolet (EUV) lithography systems. These machines are essential for manufacturing the most advanced semiconductors used in AI accelerators and data centers .

This near-insurmountable competitive moat means that every major AI infrastructure buildout flows through ASML's order book. The company's capacity upgrade plans — a 30% increase in output in each of the coming two years — are designed to keep pace with what Fouquet described as demand that now stretches into 2028 .

5. €12 Billion Share Buyback Program

ASML announced a new €12 billion share buyback program in January 2026, running through December 2028 . In Q2 2026 alone, the company repurchased roughly €1.1 billion worth of shares, with most cancelled . The buyback mechanically boosts earnings per share and signals management's confidence in future cash flows . Combined with a 17% dividend increase to €7.50 per share for 2025, ASML is returning capital at a pace that rivals best-in-class tech companies .

The Counterargument: Is the Stock Priced for Perfection?

For all the bullish signals, ASML's valuation gives pause. GuruFocus estimates the stock is 45.5% overvalued on a GF Value basis as of August 2026, with a fair value estimate of $1,196.15 against a market price of $1,740.99 . The stock has already more than doubled from its 52-week low of $710.45 and sits at a P/E ratio of 54 .

Bulls counter that a structural monopoly combined with AI-driven order acceleration justifies the premium. With a Street-high target still implying 50% upside, many see the current price as a buying opportunity rather than a top . The key risk is that any slowdown in AI capex — from regulatory changes, trade tensions, or a cyclical downturn — would hit ASML disproportionately hard given the premium multiple.

For now, the evidence points to a market that believes the AI infrastructure buildout has years left to run, and that ASML remains the single most critical supplier in that story.
