CEO Statement

"We reported third-quarter sales and gross margin that were in line with our guidance, with a strong showing of the memory segment at more than 50 percent of system sales as well as record service and field option sales. ASML continues to support our customers' technology roadmaps through product innovations as evidenced by our new NXT:1980 immersion system which provides around 30 percent overlay and 10 percent throughput improvement. These systems started shipping in Q3 with the ramp starting this quarter," ASML President and Chief Executive Officer Peter Wennink said.

"In Extreme Ultraviolet (EUV) lithography, we continue to make progress towards our 2015 productivity and availability targets. We have proven the capability both to expose 1,000 wafers per day and, in a manufacturing readiness test, to expose 15,000 wafers in four weeks. We have also achieved a four-week average availability of more than 70 percent at multiple customer sites. The first shipment of our fourth-generation EUV lithography system, the NXE:3350B, is in progress, with two more expected to ship in Q4.

"Compared to our expectation of three months ago, foundry customers are slightly more cautious with their investment plans. As a result, we expect Q4 sales below the Q3 level, but we remain on track for a record year in terms of sales. Despite slightly lower deliveries to our logic customers in Q3 and Q4, this segment clearly remains committed to ramp the 10 nanometer node, which we expect to start in Q2 2016. Currently, our memory customers indicate that their system demand will continue at a healthy level throughout the first half of 2016, albeit somewhat below the Q3 level."

Q3 Product Highlights

• Shipment of the first two TWINSCAN NXT:1980 systems. Demonstrating a more than 30 percent improvement in overlay to 1.2 nanometer (nm) and a 40 percent improvement in focus uniformity to less than 10 nm, the NXT:1980 supports increasingly demanding multiple-patterning performance requirements while boosting throughput by 10 percent to 275 wafers per hour.
• In Holistic Lithography, leading customers are using our full suite of process window enhancement solutions to optimize both scanner settings and full-chip mask patterns in immersion multiple patterning for the best yield in 1x nm node production. They have also evaluated our NXE source-mask optimization software for EUV imaging of critical layers in development of the next generation devices. It has demonstrated

substantial improvement in process window, CD uniformity and pattern placement for both 7 and 5 nm node logic and 1x nm node memory.

• The first NXE:3350B EUV system is being shipped. The system achieves an overlay of 1.0 nanometers, a 50 percent improvement over the NXE:3300B, and also features a lens with a higher transmission, which means it generates higher throughput from a given EUV power source.

Outlook

For the fourth-quarter of 2015, ASML expects net sales at approximately € 1.4 billion, a gross margin of around 45%, R&D costs of about € 270 million, other income of about € 20 million -- which consists of contributions from participants of the Customer Co-Investment Program --, SG&A costs of about € 90 million and an effective annualized tax rate of around 11%.

Update Share Buyback Program

As part of ASML's policy to return excess cash to shareholders through dividend and regularly timed share buybacks, ASML in January 2015 announced its intention to purchase up to 3.3 million shares in 2015-2016 to cover employee stock and stock option plans (ESOPs). In addition, ASML announced its intention to purchase up to EUR 750 million of shares in 2015-2016 under this program, which it intends to cancel upon repurchase. On July 14, 2015, ASML completed the purchase of 3.3 million shares for ESOPs for a total amount of EUR 314.9 million. In addition, from July 16, 2015 to September 27, 2015, ASML has acquired 1.3 million shares which will be cancelled for a total consideration of EUR 111.2 million. In total ASML has acquired 4.6 million shares under the program for a total consideration of EUR 426.1 million.

The share buyback program may be suspended, modified or discontinued at any time. All transactions under this program will be published on ASML's website (www.asml.com/investors).

Notes to the Summary IFRS Consolidated Financial Statements

Basis of Presentation

The accompanying summary consolidated financial statements are stated in millions of euros ("EUR") unless otherwise indicated.

ASML has prepared the accompanying summary consolidated financial statements in accordance with International Financial Reporting Standards as adopted by the EU ("IFRS") accounting principles generally accepted in the Netherlands for companies quoted on Euronext Amsterdam. Further disclosures, as required under IFRS in annual reports and interim reporting (IAS 34), are not included in the summary consolidated financial statements.

For internal and external reporting purposes, we apply accounting principles generally accepted in the United States of America ("US GAAP"). US GAAP is our primary accounting standard for the setting of financial and operational performance targets.

Use of estimates

The preparation of our consolidated financial statements in conformity with IFRS requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities on the balance sheet dates, and the reported amounts of net sales and costs during the reported periods. Actual results could differ from those estimates.

Basis of consolidation

The consolidated financial statements include the financial statements of ASML Holding N.V. and all of its subsidiaries and the special purpose entity of which ASML is the primary beneficiary (referred to as "ASML"). All intercompany profits, balances and transactions have been eliminated in the consolidation. Subsidiaries are all entities over which ASML has the power to govern the financial and operating policies generally accompanying a shareholding of more than 50 percent of the voting rights.

Revenue recognition

In general, we recognize the revenue from the sale of a system upon shipment and the revenue from the installation of a system upon completion of that installation at the customer site. Each system undergoes, prior to shipment, a "Factory Acceptance Test" in our cleanroom facilities, effectively replicating the operating conditions that will be present on the customer's site, in order to verify whether the system will meet its standard specifications and any additional technical and performance criteria agreed with the customer, if any. A system is shipped, and revenue is recognized, only after all specifications are met and customer sign-off is received or waived. In case not all specifications are met and the remaining performance obligation is not essential to the functionality of the system but is substantive rather than inconsequential or perfunctory, a portion of the sales price is deferred. Although each system's performance is re-tested upon installation at the customer's site, we have never failed to successfully complete installation of a system at a customer's premises.

In connection with the introduction of new technology, such as NXE:3300B, we initially defer revenue recognition until acceptance of the new technology based system and completion of installation at the customer's premises. As our systems are based largely on two product platforms that permit incremental, modular upgrades, the introduction of genuinely "new" technology occurs infrequently, and in the past 15 years, has occurred on only two occasions: 2000 (TWINSCAN) and 2010 (EUV).

The main portion of our revenue is derived from contractual arrangements with our customers that have multiple deliverables, which mainly include the sale of our systems, installation and training services and prepaid extended and enhanced (optic) warranty contracts. The revenue relating to the undelivered elements of the arrangements is deferred until delivery of these elements. Revenue from installation and training services is recognized when the services are completed. Revenue from prepaid extended and enhanced (optic) warranty contracts is recognized over the term of the contract.

Foreign currency risk management

Our sales are predominately denominated in euros. Exceptions may occur on a customer by customer basis. Our cost of sales and other expenses are mainly denominated in euros, to a certain extent in U.S. dollars, Taiwanese dollars and Japanese yen and to a limited extent in other currencies. Therefore, we are exposed to foreign currency exchange risks.

It is our policy to hedge material transaction exposures, such as forecasted sales and purchase transactions, and material net remeasurement exposures, such as accounts receivable and payable. We hedge these exposures through the use of foreign exchange contracts.

ASML – Reconciliation US GAAP – IFRS 1,2

Notes to the reconciliation from US GAAP to IFRS

Note 1 Development expenditures

Under US GAAP, ASML applies ASC 730, "Research and Development". In accordance with ASC 730, ASML charges costs relating to research and development to operating expense as incurred.

Under IFRS, ASML applies IAS 38, "Intangible Assets". In accordance with IAS 38, ASML capitalizes certain development expenditures that are amortized over the expected useful life of the related product generally ranging between one and five years. Amortization starts when the developed product is ready for volume production.

Note 2 Share-based Payments

Under US GAAP, ASML applies ASC 718 "Compensation - Stock Compensation" which requires companies to recognize the cost of employee services received in exchange for awards of equity instruments based upon the grant-date fair value of those instruments. ASC 718's general principle is that a deferred tax asset is established as we recognize compensation costs for commercial purposes for awards that are expected to result in a tax deduction under existing tax law. Under US GAAP, the deferred tax recorded on share-based compensation is computed on the basis of the expense recognized in the financial statements. Therefore, changes in ASML's share price do not affect the deferred tax asset recorded in our financial statements.

Under IFRS, ASML applies IFRS 2, "Share-based Payments". In accordance with IFRS 2, ASML records as an expense the fair value of its share-based payments with respect to stock options and shares granted to its employees. Under IFRS, at period end a deferred tax asset is computed on the basis of the tax deduction for the share-based payments under the applicable tax law and is recognized to the extent it is probable that future taxable profit will be available against which these deductible temporary differences will be utilized. Therefore, changes in ASML's share price do affect the deferred tax asset at period-end and result in adjustments to the deferred tax asset.

Note 3 Income taxes

Under US GAAP, the elimination of unrealized net income from intercompany transactions that are eliminated from the carrying amount of assets in consolidation give rise to a temporary difference for which prepaid taxes must be recognized in consolidation. Contrary to IFRS, the prepaid taxes under US GAAP are calculated based on the tax rate applicable in the seller's rather than the purchaser's tax jurisdiction.

Under IFRS, ASML applies IAS 12, "Income Taxes". In accordance with IAS 12 unrealized net income resulting from intercompany transactions that are eliminated from the carrying amount of assets in consolidation give rise to a temporary difference for which deferred taxes must be recognized in consolidation. The deferred taxes are calculated based on the tax rate applicable in the purchaser's tax jurisdiction.

This document contains statements relating to certain projections and business trends that are forward-looking, including statements with respect to our outlook, including expectations for the third quarter and second half of 2015, backlog, expected customer demand in specified market segments including memory, logic and foundry, expected trends, expected levels of service sales, systems backlog, expected financial results, including expected sales, other income, gross margin, earnings per share and R&D and SG&A expenses and effective tax rate, annual revenue opportunity for ASML, productivity of our tools and systems performance, TWINSCAN and EUV system performance (such as endurance tests), expected industry trends, statements with respect to expected system shipments, including the number of EUV systems expected to be shipped and timing of shipments and other EUV targets (including availability, productivity and shipments), the expected continuation of Moore's law, expected annual revenue growth and goals for holistic lithography, intention to return excess cash to shareholders, and statements about our dividend policy and intention to repurchase shares. You can generally identify these statements by the use of words like "may", "will", "could", "should", "project", "believe", "anticipate", "expect", "plan", "estimate", "forecast", "potential", "intend", "continue" and variations of these words or comparable words. These statements are not historical facts, but rather are based on current expectations, estimates, assumptions and projections about the business and our future financial results and readers should not place undue reliance on them. Forward-looking statements do not guarantee future performance and involve risks and uncertainties. These risks and uncertainties include, without limitation, economic conditions, product demand and semiconductor equipment industry capacity, worldwide demand and manufacturing capacity utilization for semiconductors (the principal product of our customer base), including the impact of general economic conditions on consumer confidence and demand for our customers' products, competitive products and pricing, the impact of manufacturing efficiencies and capacity constraints, performance of our systems, the continuing success of technology advances and the related pace of new product development and customer acceptance of new products, the number and timing of EUV systems expected to be shipped and recognized in revenue, our ability to enforce patents and protect intellectual property rights, the risk of intellectual property litigation, availability of raw materials and critical manufacturing equipment, trade environment, changes in exchange rates, changes in tax rates, available cash, distributable reserves for dividend payments and share repurchases, and other risks indicated in the risk factors included in ASML's Annual Report on Form 20-F and other filings with the US Securities and Exchange Commission.
