Overview

Axcelis Technologies, Inc. ("Axcelis," "the Company," "we," "us," or "our"), is a worldwide producer of equipment used in the fabrication of semiconductors. In addition, the Company provides extensive aftermarket service and support, including spare parts, equipment upgrades, and maintenance services to the semiconductor industry.

The semiconductor capital equipment industry is subject to significant cyclical swings in capital spending by semiconductor manufacturers. Capital spending is influenced by demand for semiconductors and the products using them, the utilization rate and capacity of existing semiconductor manufacturing facilities and changes in semiconductor technology, all of which are outside of our control. As a result, our revenues and gross margins, to the extent affected by increases or decreases in volume, fluctuate from year to year and period to period. The industry experienced a downturn beginning in the second half of 2007 which is expected to continue at least through 2009. Our gross margins are also affected by the introduction of new products. We typically become more efficient in manufacturing products as they mature. Our expense base is largely fixed and does not vary significantly with changes in volume. Therefore, we experience fluctuations in operating results and cash flows depending on our revenues as driven by the level of capital expenditures by semiconductor manufacturers.

The sizable expense of building, upgrading or expanding a semiconductor fabrication facility is increasingly causing semiconductor companies to contract with foundries to manufacture their semiconductors. In addition, consolidation and partnering within the semiconductor manufacturing industry is increasing. We expect these trends to continue to reduce the number of our potential customers. This growing concentration of customers may increase competitive pricing as higher percentages of our total revenues are tied to the buying decisions of a particular customer or a small number of customers.

During the three and six months ended June 30, 2009 we incurred net losses. Beginning in 2004, most customers shifted from multi wafer tools to single wafer tools for high current ion implant applications. Because we did not have a single wafer high current product, we have experienced a significant loss of market share which we have yet to regain. We introduced our single wafer Optima HD (for high current applications) product in 2006 and have begun to gain traction with this tool at a number of customers through evaluation arrangements. During the three and six months ended June 30, 2009, we recognized revenue of approximately $4.3 million and $4.5 on sales of the Optima HD, respectively.

During the three and six months ended June 30, 2009, our stock price continued to trade significantly below book value. Our inability to repay our outstanding debt in January 2009 and our

inability to generate sufficient cash flows to support ongoing operations have adversely impacted our stock price. In concert with the market uncertainty resulting from the current credit crisis, we believe that declining business and consumer confidence and increased unemployment have precipitated an economic slowdown and fears of a prolonged recession. An economic downturn characterized by higher unemployment, lower family income, lower corporate earnings, lower business investment and lower consumer spending has severely impacted many technology manufacturers and has significantly lowered the demand for our products. As mentioned above, we have lost significant market share in high current ion implant (the largest market segment in ion implant) over the past several years. We believe that we have competitive products in the high current, medium current and high energy ion implant market segments, as well as dry strip. However, challenging market conditions have severely limited our ability to increase sales and market share. We believe that a combination of these factors accounts for the difference between our stock trading price and our book value.

Continuing capital market upheavals will have an adverse effect on our Company because we are dependent on customer behavior. Our revenues would likely continue to decline in such circumstances and our profit margins would continue to erode.

Axcelis' liquidity is affected by many factors. Some of these factors are based on normal operations of the business, including acceptance of the Optima product line, and others relate to the uncertainties of global economies, including the availability of credit, and the state of the semiconductor equipment industry. Although our cash requirements fluctuate based on the timing and extent of these factors, we believe that, based on our current market, revenue and expense forecast, our existing cash and cash equivalents will be sufficient to satisfy our anticipated cash requirements at least through June 2010 and into the foreseeable future. However, if the downturn in the semicap equipment industry continues into 2010 and our operating performance does not improve significantly as compared to the six months ended June 30, 2009, there could be a significant adverse effect on our liquidity and our ability to continue in the future as a going concern.

Operating results for the periods presented are not necessarily indicative of the results that may be expected for future interim periods or years as a whole.

Critical Accounting Estimates

Management's discussion and analysis of our financial condition and results of operations are based upon Axcelis' consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates, including those related to revenue recognition, income taxes, accounts receivable, inventory and warranty obligations. Management's estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

There has been no material change in the nature of our critical accounting estimates and judgments as described in Management's Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2008.

Revenue

Product

Product revenue, which includes systems sales, sales of spare parts and product upgrades, was $25.8 million, or 76.8% of revenue, for the three months ended June 30, 2009, compared with $61.3 million, or 79.7% of revenue for the three months ended June 30, 2008. Product revenue was $43.5 million, or 73.4% of revenue for the six months ended June 30, 2009, compared with $131.1 million, or 81.0% of revenue for the six months ended June 30, 2008. System sales were $9.5 million, or 28.3% of revenue, for the three months ended June 30, 2009, compared with $37.2 million, or 48.4% of revenue for the three months ended June 30, 2008. System sales were $16.6 million, or 28.0% of revenue, for the six months ended June 30, 2009, compared with $80.3 million, or 49.6% of revenue, for the six months ended June 30, 2008. Product revenue in 2008 and 2009 has been reduced by our loss of high current market share, as discussed above. The decline in product revenue in the three and six month period ended June 30, 2009 is also attributable to a weakening semiconductor market and a related decrease in capital spending by semiconductor manufacturers, generally, exacerbated by a decrease in capacity expansion at 200mm manufacturing facilities.

A portion of our revenue from system sales is deferred until installation and other services related to future deliverables are performed. The total amount of deferred revenue at June 30, 2009 and 2008 was $9.3 million and $17.8 million, respectively. The decline was mainly due to the decrease in systems sales in 2008 and the three and six months ended June 30, 2009.

Service

Service revenue, which includes the labor component of maintenance and service contracts and fees for service hours provided by on-site service personnel, was $7.6 million, or 22.7% of revenue, for the three months ended June 30, 2009, compared with $14.2 million, or 18.5% of revenue, for the three months ended June 30, 2008. Service revenue was $15.4 million, or 26.0% of revenue for the six months ended June 30, 2009, compared with $28.2 million, or 17.4% of revenue for the six months ended June 30, 2008. Although service revenue should increase with the expansion of the installed base of systems, it can fluctuate from period to period based on capacity utilization at customers' manufacturing facilities, which affects the need for equipment service. The decline during the three and six months ended June 30, 2009 was primarily due to the continuing depressed fabrication utilization in the semiconductor industry.

Royalties

Royalty revenue was $0.2 million, or 0.5% of revenue, for the three months ended June 30, 2009, compared with $1.4 million, or 1.8% of revenue, for the three months ended June 30, 2008. Royalty revenue for the six months ended June 30, 2009 was $0.4 million, or 0.6% of revenue, compared to $2.5 million, or 1.6%, of revenue for the six months ended June 30, 2008. Royalties were earned primarily under our prior license agreement with SEN Corporation, an SHI and Axcelis Company ("SEN"). Until March 30, 2009, we owned 50% of the equity of a joint venture with Sumitomo Heavy Industries, Ltd. ("SHI") in Japan. This joint venture, known as SEN, licensed technology from us relating to the manufacture of specified ion implantation products and had exclusive rights to manufacture and sell these products in the territory of Japan. Changes in royalty revenue were mainly attributable to fluctuations in SEN sales volume based on demand for equipment by Japanese semiconductor manufacturers and the timing of shipments in Japan. As a result of the sale of the

Company's investment in SEN, on March 30, 2009, SEN has no further obligation to pay royalties to the Company.

Ion Implant

Revenue from sales of ion implantation products and service accounted for $27.3 million, or 81.4% of total revenue, in the three months ended June 30, 2009, compared with $63.9 million, or 83.1% of total revenue, for the three months ended June 30, 2008. Revenue from sales of ion implantation products and service accounted for $49.5 million, or 83.5% of revenue, for the six months ended June 30, 2009, compared to $133.8 million, or 82.7% of revenue, in the six months ended June 30, 2008. The decline was due to the factors discussed above for product revenues.

Aftermarket

The Company's product revenues include sales of spare parts and product upgrades as well as complete systems. We refer to the business of selling spare parts and product upgrades, combined with the sale of maintenance labor and service contracts and service hours, as the "aftermarket" business. The revenue from our aftermarket business was $23.9 million for the three months ended June 30, 2009, compared to $38.3 million for the three months ended June 30, 2008. The revenue from our aftermarket business was $42.3 million for the six months ended June 30, 2009, compared to $78.9 million for the six months ended June 30, 2008. Aftermarket revenue generally increases with expansion of the installed base of systems but can fluctuate period to period based on capacity utilization at customers' manufacturing facilities which affects the sale of spare parts and demand for equipment service. The decline during the three and six months ended June 30, 2009 was primarily due to the continuing depressed fabrication utilization in the semiconductor industry.

Gross Profit

Product

Gross profit from product revenue was 12.1% for the three months ended June 30, 2009, compared to gross profit of 31.2% for the three months ended June 30, 2008. Approximately 7.5% of the 19.1% decrease resulted from an additional provision for excess inventory. The remaining 11.6% decrease is attributable to significantly lower system sales volume during the three months ended June 30, 2009 and the related under absorption of manufacturing overhead, which reduced gross margins by 24.3%, offset by a 12.7% increase in gross margin resulting from the favorable impact of an increased mix of parts and upgrade revenue at higher margins. Gross profit from product revenue was 6.0% for the six months ended June 30, 2009, compared with 31.2% for the six months ended June 30, 2008. Approximately 15.0% of the 25.2% decrease resulted from an additional provision for excess inventory. The remaining 10.2% decrease is attributable to significantly lower systems sales volume during the six months ended June 30, 2009 and the related under absorption of manufacturing overhead, which reduced gross margins by 24.5%, offset by a 14.3% increase in gross margin resulting from the favorable impact of an increased mix of parts and upgrade revenue at higher margins.

Service

Gross profit from service revenue was 34.2% for the three months ended June 30, 2009, compared to 46.2% for the three months ended June 30, 2008. Gross profit from service revenue was 38.3% for the six months ended June 30, 2009, compared to 45.6% for the six months ended June 30, 2008. The decrease in gross profit is attributable to significantly lower volumes.

Research and development expense was $7.8 million in the three months ended June 30, 2009, a decrease of $9.2 million, or 54.1%, compared with $17.0 million in the three months ended June 30, 2008. The decrease was due to decreased payroll costs ($3.8 million), decreased consulting costs ($1.0 million), decreased project material costs ($1.6 million), decreased development asset amortization and depreciation costs ($2.2 million) and decreased other miscellaneous expenses ($0.6 million). Research and development expense was $17.3 million for the six months ended June 30, 2009, a decrease of $16.5 million or 48.8%, compared with $33.8 million for the six months ended June 30, 2008. The decrease was due to decreased payroll costs ($7.0 million), decreased consulting costs ($1.6 million), decreased project material costs ($2.5 million), decreased development asset amortization and depreciation costs ($4.3 million) and decreased other miscellaneous expenses ($1.1 million).

Research and development expense was attributable to the following activities for the six months ended June 30, 2009: 51% for new product development, 32% for improvement of existing products, and 17% for product testing.

Sales and Marketing

Sales and marketing expense was $6.3 million in the three months ended June 30, 2009, a decrease of $6.2 million, or 49.6%, compared with $12.5 million for the three months ended June 30, 2008. The decrease was due to decreased payroll costs ($3.0 million), decreased professional fee expenses ($0.9 million), decreased supplies and marketing service expenses ($1.2 million), decreased travel costs ($0.7 million), decreased freight costs ($0.3 million), and decreased other miscellaneous expenses ($0.1 million). Sales and marketing expense was $13.2 million for the six months ended June 30, 2009, a decrease of $11.2 million, or 45.9%, compared with $24.4 million for the six months ended June 30, 2008. The decrease was driven primarily by decreased payroll costs ($5.7 million), decreased professional fee expenses ($1.8 million), decreased supplies and marketing service expenses ($1.5 million), decreased travel cost ($1.3 million), decreased freight costs ($0.6 million), and decreased other miscellaneous expense ($0.3 million).

General and Administrative

General and administrative expense was $8.5 million for the three months ended June 30, 2009, a decrease of $2.4 million or 22%, compared with $10.9 million in the three months ended June 30, 2008. The decrease was due to decreased payroll costs ($1.6 million), decreased professional fee expenses ($0.3 million), decreased amortization expense ($0.2 million) and decreased other miscellaneous expenses ($0.3 million). General and administrative expense was $19.2 million for the six months ended June 30, 2009, a decrease of $1.5 million, or 7.2%, compared with $20.7 million in the six months ended June 30, 2008. The decrease was due to decreased payroll costs ($2.5 million), decreased amortization costs ($0.4 million), decreased other miscellaneous expenses ($0.5 million), offset by increased professional fees ($1.9 million).

Restructuring

For the three and six months ended June 30, 2009, we implemented a reduction in force to further reduce costs to mitigate deteriorating industry fundamentals. This reduction in force resulted in a total charge to expense of approximately $5.6 million related to separation and outplacement costs for the six months ended June 30, 2009, offset by a reversal of $0.5 million of accrued compensation expense related to terminated employees. A charge to expense of $4.6 million was recorded in the three months ended June 30, 2009, offset by a reversal of $0.5 million of accrued compensation expense related to terminated employees.

The sale of the Company's investment in SEN resulted in a gain of approximately $1.1 million for the six months ended June 30, 2009. This gain includes net proceeds of $122.2 million and cumulative foreign translation gain of $23.5 million, previously recorded in other comprehensive income, reduced by the carrying value of the investment on the date of sale of $144.6 million.

No equity loss or income was attributable to SEN for the three months ended June 30, 2009. Equity loss attributable to SEN was $3.2 million for the six months ended June 30, 2009. Equity loss attributable to SEN was $0.1 million for the three and six months ended June 30, 2008. As a result of the sale of the Company's investment in SEN, subsequent to March 30, 2009, the Company no longer records equity income or loss from SEN.

Interest income decreased by $0.4 million and $1.0 million from the three and six months ended June 30, 2009, compared to the three and six months ended June 30, 2008, due primarily to lower average cash balances.

Interest expense decreased by $1.7 million and $1.6 million for the three and six months ended June 30, 2009, compared to the three and six months ended June 30, 2008. The decrease for the three and six months ended June 30, 2009 is due to the payment in full of the convertible senior subordinated notes at March 30, 2009.

Income Taxes (Credits)

We incur income tax expense relating principally to operating results of foreign entities in jurisdictions, principally in Asia, where we earn taxable income. We have significant net operating loss carryforwards in the United States and certain foreign jurisdictions, principally Europe, and, as a result, we do not currently pay significant income taxes in those jurisdictions and we do not recognize the tax benefit for such losses as discussed in Note 11 to the consolidated financial statements. Accordingly, our effective income tax rate is not meaningful.

Liquidity and Capital Resources

Our liquidity is affected by many factors. Some of these relate specifically to the operations of our business, for example, the rate of acceptance of the Optima product line, and others relate to the uncertainties of global economies, including the availability of credit, and the condition of the overall semiconductor equipment industry.

During the three and six months ended June 30, 2009, we experienced negative cash flows from operations. Cash used for operations was predominately driven by the net loss from operations attributable to the depressed semiconductor equipment market and the resultant decline in revenues. Unrestricted cash and cash equivalents at June 30, 2009 were $49.8 million, compared to $37.7 million at December 31, 2008. The $12.1 million increase in cash and cash equivalents is primarily attributable to proceeds from the sale of our Investment in SEN on March 30, 2009, partially offset by repayment of our Convertible Senior Subordinated Notes and cash used in operations.

On March 30, 2009, pursuant to the Share Purchase Agreement with SHI and SEN, we sold all of our common shares in SEN to SHI for proceeds of $132.8 million before advisor fees and other expenses of $10.6 million, of which $7.1 million was paid during the quarter ended June 30, 2009. We used $86.4 million ($83.3 million principal and $3.1 million accrued interest and bank fee), of that amount to pay in full our outstanding obligations on our 4.25% Convertible Senior Subordinated Notes.

Our 2009 cash position will be driven by reductions in working capital, as inventory for the Optima product line is converted into revenue.

On April 23, 2008, we entered into a revolving credit facility with a bank that provides for borrowings up to the lesser of $50 million or specified percentages of the amounts of qualifying accounts receivable and inventory. We are currently unable to borrow against the facility because we are not currently, and do not expect to become, in compliance with the financial covenants contained in the underlying credit agreement. This facility expires in April 2010. If we terminate this revolving credit facility prior to its expiration, we will have to pay an early termination fee of approximately $0.5 million as of the date of termination.

We do not currently have access to any other source of credit. We are continuing to explore new financing sources. However, in light of the current negative economic environment, including the prolonged downturn in the semiconductor and semicap equipment industries, and the negative effect it has had on the Company's results of operations, financial position, liquidity, and the lending environment, we anticipate that it would be very difficult for us to obtain significant new credit on favorable terms, if at all.

We believe that based on our current market, revenue and expense forecasts our existing cash and cash equivalents and the net proceeds from the sale of our SEN investment will be sufficient to satisfy our anticipated cash requirements at least through June 2010 and into the foreseeable future. However, if the downturn in the semicap industry continues into 2010 there could be a significant adverse effect on our liquidity and our ability to continue in the future as a going concern.
