Outlook

Q4 2007 outlook ASML expects to ship 55 systems ASP for new + refurbished systems expected to be &128; 15.0 million Gross margin between 40 - 41% R&D is expected at &128; 125 million net of credit SG&A will remain at &128; 56 million

Market conditions - ASML growth drivers Short term: Flash Improving order trend led by Flash memory Ongoing capacity additions at 55 nm node 4 and 8 Gb Flash densities require 45 nm imaging Strong Flash unit growth expected Mid term: DRAM DRAM invests in immersion for 55 nm for higher density chips Installing immersion to reduce cost as price pressure continues Reduced DRAM unit growth expected Cost-driven factory conversions from 200 to 300 mm wafers Long term: Foundries Year ending utilization rates are high Litho purchases required to support industry growth

2007 - 2008 Outlook Q4 order intake will exceed Q3 bookings Potential for revenues over the first 3 quarters of 2008 to exceed the first 3 quarters of 2007
