ASML announces customer co-investment program aimed at accelerating innovation

VELDHOVEN, the Netherlands, July 9, 2012—ASML Holding NV announces today that it has established a program to enable minority equity investments in ASML by its largest customers in addition to commitments to fund ASML’s research and development (R&D) spending for future programs. The objective of the program is to accelerate ASML’s development of Extreme Ultraviolet (EUV) technology beyond this current generation and ASML’s development of future 450 mm silicon wafer technology, both due in the second half of this decade.

As part of this program, ASML may issue up to an aggregate 25 percent minority equity stake to customers. The entire cash proceeds from the share issuance will be returned to ASML shareholders (not including participating customers). Alongside these equity investments, participating customers would fund a significant portion of ASML’s research and development (R&D) activities for the next five years.

Intel is the first participant in the customer co-investment program, and has committed to acquire up to a 15% equity ownership interest at a subscription price of EUR 39.91 per share¹, and to also provide EUR 829 million to ASML in R&D funding, which will be dedicated to the development of 450 mm and EUV technology. Additionally, Intel has contractually committed to advance purchase orders for 450 mm and EUV development and production tools from ASML to support technology and infrastructure development under agreed upon conditions of sales.

Other customers are currently evaluating joining the program.

“This funding and participation by a leading semiconductor manufacturer is an acknowledgement of the essential contribution of lithography technology in ensuring the continuation of Moore’s Law. Moore’s Law, which stipulates that transistor density and microchip performance doubles roughly every 18 months, requires ever-increasing investments by the semiconductor industry, and in particular the equipment industry. We

welcome Intel as the first customer to agree to contribute to these investments, the results of which will be available to every semiconductor manufacturer with no restrictions,” said Eric Meurice, Chief Executive Officer of ASML. “We hope to be able to announce additional investments by our other customers in the coming weeks.”

“Circuit design scaling and enhanced productivity in wafer manufacturing technologies, especially lithography, are direct enablers of Moore’s Law which provides economic benefits to consumers,” said Brian Krzanich, Intel Senior Vice President and Chief Operating Officer. “This investment will reinforce EUV technology development and enable 450 mm prototype systems as early as 2015, allowing the industry to accelerate process development and manufacturing productivity programs. By using EUV technology, the industry will be able to scale geometries further. By moving from today’s standard 300 mm wafers to new larger 450 mm wafers, the industry can effectively double the capacity of its factories for only a fraction of the cost. This collaboration enhances our ability to improve shareholder and customer value through significant capital productivity improvement benefits.”

Transaction details

If the maximum aggregate 25% available shares are fully subscribed, customers would have acquired the shares for an aggregate value of EUR 4.19 billion², and would have committed R&D funding of EUR 1.38 billion, to be received over the period 2013 to 2017.

The program consists of two funding projects: a 450 mm technology development project and a next-generation EUV development project.

Under the terms of the agreement, ASML will first issue new shares equivalent to 9.99% of ASML’s issued share capital (the” First Issuance”), to Intel in exchange for EUR 1.7 billion in cash. In addition, Intel has committed EUR 553 million of R&D funding to accelerate ASML’s 450 mm silicon wafer technology development. ASML can issue the shares under the First Issuance as per the decisions made at ASML’s 2012 Annual General Meeting of shareholders. Subject to shareholders’ approval at an Extraordinary General Meeting of shareholders (“EGM”) to be scheduled for September 2012, the entire cash proceeds from the First Issuance will be returned to ASML shareholders (not including participating customers) through a synthetic buy-back as described below.

ASML intends to issue the remaining shares in the program (the “Second Issuance”), up to a total of 15% of ASML’s issued share capital, the proceeds of which will also be returned to shareholders (not including participating customers) through a synthetic buy-back. The Second Issuance, as well as the synthetic buy-back, are subject to the approval of ASML’s shareholders at the EGM. Of this 15%, Intel has agreed to purchase 5% of ASML’s issued share capital and will commit EUR 277 million R&D funding for the EUV project upon approval by ASML shareholders. Other customers are currently considering the opportunity to invest in the remaining available 10% of ASML’s issued share capital under the Second Issuance, on the same basic terms as Intel and at a price not lower than the Intel price. If shareholder approval is not obtained at the EGM, there will be neither a synthetic buyback nor a Second Issuance, in which case the number of our issued shares would increase by 9.99% (the First Issuance), with Intel remaining obligated to fund the 450 mm technology development project.

The customer co-investment program is intended to have no effect on the total current number of ASML shares outstanding. Following the receipt from participating customers of the aggregate subscription proceeds from the First Issuance and the Second Issuance, ASML will effect a synthetic buy-back, consisting of a repayment to shareholders of the aggregate subscription proceeds and a reverse stock split. The shares purchased by participating customers will be excluded from the synthetic buy-back. ASML has used a similar synthetic buy-back process in 2007 as an efficient way of executing large buy-backs for its own share repurchase program: 55,093,409 shares were repurchased in this manner for a total amount of EUR 1,012 million.

The shares issued through the program to ASML customers will be held by a foundation (Stichting Administratiekantoor) until a relevant termination event occurs; in order to ensure ASML’s strategic and operational independence, these shares will be non-voting, except in limited extraordinary circumstances, and will be subject to a lock-up. As part of these arrangements, any single customer would not increase its holdings in ASML above 19.9% for a period of six years.

The terms of the proposed synthetic buy-back and the Second Issuance will be subject to approval by ASML shareholders at the EGM and statutory provisions regarding repayment of capital. In addition, the participation of Intel in the customer co-investment program will be subject to customary regulatory approvals, including the termination of waiting periods applicable under the U.S. Hart-Scott-Rodino (HSR) Act.

For regulatory reasons, in connection with the transactions described in this press release, ASML has suspended its regular share buy-back programs until further notice. ASML intends to resume share buy-backs when permitted under applicable regulations.

About the Semiconductor Lithography industry

A critically important aspect of this transaction is the provision for additional funding of ASML’s industry-leading EUV and 450 mm development work. Current lithography technologies are being stretched to enable the industry to deliver smaller, faster, cheaper, and lower power devices through smaller geometries on advanced manufacturing nodes. However, this results in increased manufacturing complexity and capital expenditures through Multiple Patterning whereby silicon wafers are processed multiple times to etch the finest geometric patterns onto the silicon. With the successful introduction of EUV lithography in high-volume manufacturing, multiple processing steps on critical layers can be eliminated on advanced manufacturing nodes, resulting in substantial manufacturing productivity gains, product power and performance enhancements, and lower capital expenditures. Transition from 300 mm wafer size to 450 mm wafer size will further increase manufacturing efficiencies for very high volume manufacturing.
