Outlook

“2012 fourth-quarter and full year sales and profit came in as expected, making the year our second best ever. The high level of sales was mainly supported by the large 28-32 nanometer (nm) capacity investment made by the Foundry industry, while Memory capacity investments represented only 25 percent of total net sales, never really picking

up, as its major driver, the PC business, shrunk compared to 2011. We plan net sales for 2013 at a similar level to that of 2012, with a slow Q1 start, recovering in Q2 and a relatively large second half. This full-year perspective is supported by two engines that are less dependent on macroeconomic circumstances: Firstly, there is a strategic technology transition need for very lithography-intensive 14-20 nm foundry and logic nodes, which will enable the next generation portable products, for which all semiconductor architecture leaders have designs pending and need initial capacity. Secondly, ASML will ship its first NXE:3300B EUV tool in Q2 targeting for a maximum of 11 potential shipments in 2013, representing a net sales value of around EUR 700 million. We are encouraged by the latest EUV development performance as we have now demonstrated a stable 40 Watts of EUV source power against a production target of 105 Watts. Also, the source design was tested successfully at up to 60 Watts for debris mitigation. Furthermore, the NXE:3300B first system has shown good overlay and imaging performance. We expect the DRAM and NAND Flash memory segments to continue investing at a minimum level in 2013, generating an upside revenue opportunity for ASML if the PC business picks up with good related Solid State Drive attach rates,” said Eric Meurice, President and Chief Executive Officer of ASML.

For the first quarter of 2013, ASML expects net sales of about EUR 850 million, gross margin of about 38 percent, R&D costs of EUR 185 million, other income of EUR 16 million which consists of contributions from participants of the Customer Co-Investment Program and SG&A costs of EUR 63 million including EUR 6 million in expenses related to the pending Cymer acquisition.

Fourth-Quarter Product Highlights

• Our TWINSCAN NXT lithography system has achieved record matched machine overlay of less than 4 nm, a 2 nm improvement.

• Holistic Lithography continued to expand and integrated metrology and feedback loops which enable shrink, reduce drift and improve yield contributed to record sales from service and field options of EUR 257 million.

• In our EUV program, our NXE:3100 pre-production systems have exposed a cumulative total of more than 30,000 wafers at customer sites, enabling successful recipe development for the sub-14 nm Logic and 22 nm DRAM nodes, which may soon lead to additional orders for production systems for delivery targeted in 2014.

• Imaging of the NXE:3300B, the system intended for high-volume manufacturing, continues to improve, shows excellent results down to 14 nm. The first NXE:3300B customer system is in final stage of test and qualification in our cleanroom in Veldhoven.

• Progress towards an EUV light source powerful enough for high-volume manufacturing has been encouraging and steady: We have seen in the past quarter results from the first fully integrated EUV source with stable full-field expose power of up to 40 Watts with good dose control over extended time. This allows us to prepare initial shipments of the NXE:3300B and gives us confidence in the ability to implement improvements over time to power levels enabling 70 wafers per hour at customers mid-2014.

• For our new 450mm development program, ASML is expanding the design team in line with the targeting of pre-production systems for 2016 and production for 2018

Cash return programs

Due to ASML’s strong financial position and operating cash flow prospects, we intend to continue to return excess cash to shareholders through increasing dividends and share buy back programs, thus supporting our shareholders in their continued investment in ASML.

ASML intends to again increase the dividend by 15 percent compared with last year. Therefore, we will submit a proposal to the 2013 Annual General Meeting of Shareholders (AGM) to declare a dividend in respect of 2012 of EUR 0.53 per ordinary share (for a total amount of approximately EUR 215 million), compared with a dividend of EUR 0.46 per ordinary share paid in respect of 2011. The proposed dividend represents 19.6 percent of earnings per share in 2012.

For regulatory reasons, ASML will not announce any new share buy back program before Cymer’s Extraordinary General Meeting of Shareholders, which will be held on 5 February 2013.

Additional information

• In the fourth quarter, we announced the intended cash-and-stock acquisition of lithographic light source supplier Cymer. As part of the regulatory review process, clearance has been granted by the U.S. Committee on Foreign Investment in the United States (CFIUS) and German anti-trust authorities. We continue to expect the transaction to close in the first half of 2013.

• In the fourth quarter ASML released EUR 119.5 million of its liability for unrecognized tax benefits after successful conclusion of tax audits in different jurisdictions, which resulted in a net tax benefit of EUR 115.8 million for the quarter. The release of the liability for unrecognized tax benefits almost completely offsets the income tax due over ASML’s earnings for the year.

• SG&A of EUR 79.5 million reflected exceptional additional costs of EUR 14 million, related to the acquisition offer for Cymer.
