ASML ANNOUNCES 2003 FIRST QUARTER RESULTS


VELDHOVEN, the Netherlands, April 16, 2003 - ASML Holding NV (ASML) today
announced its first quarter 2003 results as follows:

    o    Sales of 33 lithography systems - 27 new and 6 refurbished systems -
         up from Q1 02 sales of 13 lithography systems, including 1
         refurbished system;
    o    Increase in average selling price to EUR 9.2 million, up 10 percent
         from a Q1 02 average selling price of EUR 8.4 million;
    o    Net loss of EUR 82 million or EUR .17 per ordinary share, compared
         with a Q1 02 net loss of EUR 108 million or EUR .23 per ordinary
         share;
    o    Cash generation of EUR 40 million in Lithography, up from Q1 02 cash
         usage in Lithography of EUR 194 million;
    o    Continued improvements in working capital of EUR 92 million;
    o    Pre-tax loss from Discontinued Operations narrowed to EUR 22 million,
         including one-time charges of EUR 11 million in Q1 03, from EUR 33
         million in Q1 02.


Commenting on Q1 03 results, Doug Dunn, president and CEO, ASML said:

"Historically, the first quarter is a weak quarter. Our results reflect that
trend as well as a poor global economy, generally, and a continued depressed
market in the semiconductor industry, specifically. The same factors that
affect consumer confidence resonate throughout the semiconductor supply chain
also affecting equipment manufacturers.

"However, within this tough environment, we continued to generate cash,
increased worldwide market share according to industry analysts and
implemented actions to lower our breakeven level. Despite difficult business
conditions, ASML continued to outpace the competition and maintain its
commitment to leadership."


Lithography - Continuing Operations

Total net sales in the first three months of 2003 were EUR 318 million as
compared with total net sales of EUR 179 million for the first three months of
2002. This reflects a net increase of EUR 139 million or a 78 percent increase
year-on-year from the same quarter last year.

As of March 31, 2003, the order backlog for lithography systems was 87 units
with a total value of EUR 870 million. This compares with an order backlog for
lithography systems of 103 units with a value of EUR 1,077 million as of
December 31, 2002. The order backlog reflects the number of systems ordered to
date by customers for shipment over the following 12-month period. ASML
continues not to issue guidance or forecasts due to uncertain market
conditions.

The total gross margin for lithography operations in the first quarter 2003
was 16.6 percent, compared to a gross margin of 9.6 percent in the first
quarter 2002. The gross margin was depressed due to continued price pressure
and the relatively low number of product shipments causing under-utilization
of manufacturing capacity and facilities. Due to better fixed-cost coverage,
gross margin improves during financial quarters if shipments are higher.

Track and Thermal - Discontinued Operations

As previously announced, ASML decided to terminate its Track equipment
activities in 2002 and sell its Thermal operations in 2003. The decision
resulted in a first quarter 2003 net loss from Discontinued Operations of EUR
13 million, compared with a first quarter 2002 net loss of EUR 22 million.
This decrease was due to lower operating losses resulting from the termination
of Track activities but was offset by valuation allowances for buildings and
the results of previously announced cost cutting measures in the Thermal
business, which ASML still intends to sell during 2003.

Please note: Results for 2002 have been restated to reclassify Track and
Thermal activities as Discontinued Operations.

Financial Position

In the first quarter 2003, the Lithography operation generated EUR 40 million
in cash from operating, investing and financing activities while the Track and
Thermal business used EUR 12 million. In addition, there was the negative
impact on cash of EUR 8 million due to foreign exchange rate fluctuations.
This compares with 2002 first quarter totals of EUR 194 million in cash used
by the Lithography operation and EUR 7 million used by the Track and Thermal
business.

In the second half 2002, ASML implemented measures focused on improving its
working capital management and reducing headcount. These measures contributed
to the company ending the first quarter with a cash balance of EUR 688
million, up from EUR 669 million as of December 31, 2002. The company is still
on target to reach the intended size of its lithography operation, 5,200
employees, by July 2003. ASML will continue its increased efforts to improve
the collection of accounts receivable and current tax assets, reduce inventory
and manage accounts payable, among other measures.


ASML also remains focused on its target of achieving a balance of cash and
cash equivalents in excess of EUR 1 billion by year-end 2003.

Additional Financial Information

Selling, general and administrative (SG&A) costs were EUR 61 million in the
first quarter 2003, compared with first quarter 2002 SG&A costs of EUR 61
million. Restructuring expenses relating to the cost cutting measures
announced on December 18, 2002, still estimated at less than EUR 10 million in
costs for this year, amounted to EUR 6 million for this quarter.

Net research and development costs for Lithography for the first quarter 2003
was EUR 76 million, an increase of EUR 7 million compared with the first
quarter of 2002. The rise is due to the timing of research and development
costs for leading-edge products, particularly 93-nanometer technology.
