ASML to Establish Center of Excellence in Taiwan

VELDHOVEN, the Netherlands, April 4, 2007 — ASML announced today that it has signed a contract with the Taiwanese Ministry of Economic Affairs (MOEA) to establish the ASML Center of Excellence (ACE) near Taipei. This follows the Letter of Intent ASML and MOEA signed late last year; ASML expects that ACE will be fully operational in Q2 2008 after construction is scheduled to be completed. ASML is currently recruiting personnel for ACE and has secured a temporary facility.

ACE will reinforce ASML’s commitment to customers in the Asia-Pacific region by focusing on technology and applications development, equipment support, training, logistics, and refurbishment. ACE will also enable local sourcing of equipment modules, components and services.

“The entire Asia-Pacific region is a key market for ASML; collectively it accounted for nearly two-thirds of our sales in 2006,” said Eric Meurice, president and CEO. By establishing ACE, we will ensure that ASML continues to meet the growing demands of customers throughout this important region.” The Semiconductor Industry Association predicts that the entire Asia-Pacific region will see 12 percent growth year over year in 2007, outpacing industry growth in the rest of the world.

ASML is actively recruiting qualified candidates to work at ACE for customer support, training, application development, development and engineering, logistics, sourcing, and refurbishment and repair. Interested candidates should visit ASML’s virtual cleanroom at www.careers.asml.com for more information.

Backlog summary Backlog value increased due to: Immersion bookings (wet ArF) valued at € 197 million or 21% of total bookings Dry ArF bookings valued at € 435 million or 47% of total bookings Q1 bookings strength is related to leading edge capacity additions and process development tools for shrink Steep increase of backlog ASP from € 13.2 to € 14.6 due to transition to technology buys from general capacity expansion

Market

Trends by sector - Flash Gartner Dataquest forecast 48% flash unit growth in 2007 ASML's current shipment plan supports forecast with no significant overcapacity in flash by the end of 2007 Sensitivity studies around the forecast indicates that a +/- 10% demand variation results in a +/- 1 calendar quarter shift in supply/demand balance Some production capacity reallocated to DRAM due to low flash prices and overcapacity in H1 2007 Flash is using immersion in production at the 6x node and ramping the 5x node

Trends by sector - DRAM Gartner Dataquest forecast 36% DRAM unit growth in 2007 ASML's current shipment plan supports forecast with no overcapacity in DRAM by the end of 2007 Sensitivity studies around the forecast indicates that a +/- 5% demand variation results in a +/- 1 calendar quarter shift in supply/demand balance DRAM price pressure forces manufacturers to speed up the ramp of 7x volume manufacturing for 1 Gbit and 2 Gbit products Immersion in volume manufacturing will start in 2008/2009 at the 5x node

Trends by sector - Foundry and IDM Foundry Utilization in factories appears to have bottomed in Q1 16% of Q1 bookings in value are received from foundries Announced to ramp immersion by the end of 2007 with volume manufacturing starting in 2008/2009 IDM IDM investment level is in-line with industry analyst forecasted IC unit growth of 10-11% 38% of Q1 bookings in value are received from IDM's

Accomplishments

Q1 accomplishments Growth Revenue 960 million, up 53% year-on-year Record high backlog at € 2,163 million Brion acquisition completed Profitability Recurring net income (excluding amortization in process R&D Brion) at 176 million or 18.3 % of sales Gross margin at 40.9% Cash Cash flow from operations € 173 million

Brion accomplishments Integration with ASML has begun and in progress Brion leads the worldwide market for optical proximity correction (OPC) verification, and is rapidly expanding in the OPC market Over 20 semiconductor manufacturers utilize Tachyon to verify their designs With Brion products there is no compromise between accuracy and speed Only commercially available and production proven one-model-across- process-window Fastest time to accurate model in the industry Tachyon 2.0 was announced during SPIE Tachyon 2.0 is Brion's 2nd generation, image-based hardware- accelerated computational lithography platform

Excess cash strategy - improving shareholder value ASML is a growth company Regular share buybacks is optimum instrument to create significant value Dividend is certainly an option in slower growth model ASML will maintain a strong gross cash liquidity buffer of M€1,000 to M€1,500 and use upside cash for buy backs Efficiency of capital structure is regularly reviewed Repurchased approx. 8 million shares in Q1 2007 Received authorization from shareholders to buy back additional shares

Q2 2007 outlook ASML expects to ship 69 systems ASP for new + refurbished systems expected to be € 12.0 million Gross margin will range between 40 - 41% R&D is expected to increase to € 120 million net of credit (including Brion) to strengthen technology leadership and enabling lithography growth SG&A will remain at € 56 million Continuous focus on flexibility of OPEX costs ASML can scale back on R&D by 30% and SG&A by 10% within a quarter

Immersion

XT:1700i performance XT:1700i's are now running in production Imaging down to 45 nm Overlay less than 7 nm Productivity greater than 122 wafers per hour Defect levels improving continuously Proven production machine output well over 1000 wafers per day per machine with a clear roadmap to 2000 wafers per day XT:1700i is the only immersion tool in the world capable of printing 45nm resolution in production

Knowledge gathered with over 40 machines at 19 customers The large installed base has enabled ASML to: Build knowledge on immersion process specifics for all customer segments (logic, foundry, memory, microprocessors) Develop best practices for immersion related defect optimization to enable high yield manufacturing at our customers Use customer feedback to improve on tool performance to ensure volume manufacturing stability and productivity requirements

XT:1900i - 5th generation immersion Only system available specified at 40 nm resolution and below in volume manufacturing First shipment planned for early Q3 2007 Evolutionary single barrel catadioptric lens shows excellent performance
