Solid order book supports robust H1 revenue Backlog is 89 systems valued at &128; 1,697 Million 78% of backlog is shippable in the next 6 months Immersion represents 60% of backlog Solid IDM demand - 26% of backlog - underpins the non memory portion of backlog Limited exposure to second tier DRAM manufacturers - 9% of backlog

Significance of the immersion market in 2008 ASML immersion net sales expected to almost double in 2008 Volume of immersion systems will lead to significant system ASP growth Further market gains in Japan expected based upon highest productivity with 14 immersion systems installed productivity with 14 immersion systems installed productivity with 14 immersion systems installed productivity with 14 immersion systems installed productivity with 14 immersion systems installed productivity with 14 immersion systems installed

ASML: In the "sweet spot" of semiconductor equipment supply Lithography: the enabler of shrink for lower cost per chip Lithography benefits from multiple growth drivers Industry segment growth Process complexity driving more litho layers Higher ASP tools ASML reaping the reward of immersion leadership

Business performance

8 Quarters of robust Operating Margin performance ASML Operating Margin

Improving shareholder value in 2007 In 2007, ASML returned &128; 1,372 million to shareholders through share buyback programs and a capital repayment Reduced outstanding shares by 72 million shares Issued 26 million shares for convertible bond redemption The number of outstanding basic shares reduced in 2007 to 436 million shares at the end of the year

Improving shareholder value going forward ASML is committed to return cash above its target cash & cash equivalents buffer of &128; 1 billion to &128; 1.5 billion to shareholders The share buyback program of 14 million shares to cover for outstanding employees stock options has been completed ASML is confident about its ability to generate cash above operational needs in 2008 We will consider all available opportunities to return excess cash to shareholders including: share buy back capital repayment dividend

Outlook

Q1 2008 outlook ASML expects to ship 50 systems ASP for new + refurbished systems expected to be &128; 16.3 million Gross margin between 40 - 41% R&D is expected at &128; 127 million net of credit SG&A is expected at &128; 58 million

2008 Outlook Although independent market researchers still expect a double digit increase in demand for integrated circuit units in 2008, which should translate into lithography market expansion in 2008, we are awaiting confirmation of this potential growth through the exact level of Q1 and Q2 bookings We remain optimistic, in view of our customers' large immersion technology needs, their high level of capacity utilization, and the low IC inventory levels in the market
