Notes to Consolidated Financial Statements (Unaudited)

Note 1.  Nature of Business

Axcelis Technologies, Inc. (“Axcelis” or the “Company”) was incorporated in Delaware in 1995, and is a worldwide producer of ion implantation and other processing equipment used in the fabrication of semiconductor chips in the United States, Europe and Asia. In addition, the Company provides extensive aftermarket service and support, including spare parts, equipment upgrades, used equipment and maintenance services to the semiconductor industry.

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments which are of a normal recurring nature and considered necessary for a fair presentation of these financial statements have been included. Operating results for the interim periods presented are not necessarily indicative of the results that may be expected for other interim periods or for the year as a whole.

The balance sheet at December 31, 2015 has been derived from the audited financial statements at that date but does not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. For further information, refer to the consolidated financial statements and footnotes thereto included in Axcelis Technologies, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2015.

Note 2.  Correction of Accounting Error in Prior Period

Subsequent to March 31, 2016, but prior to filing the Form 10-Q for the quarter ended June 30, 2016, the Company discovered a cumulative error associated with the elimination of profits on sales of inventory to its subsidiaries.  This error had no impact upon the Company’s consolidated statement of operations or consolidated statement of cash flows subsequent to the year ended December 31, 2010.  The following financial statement line items reported in the Company’s consolidated balance sheets for the years ended December 31, 2015 and 2014 were affected by the correction of this accounting error:

(in thousands)	Previously Reported December 31, 2015			Adjusted December 31, 2015	Effect of Change
Inventory, net	$	115,904	$	109,408	$	(6,496)
Total current assets		236,453		229,957		(6,496)
Total assets		288,280		281,784		(6,496)
Accumulated deficit		(336,209)		(342,705)		(6,496)
Total stockholders' equity		190,260		183,764		(6,496)
Total liabilities and stockholders' equity	$	288,280	$	281,784	$	(6,496)
(in thousands)	Previously Reported December 31, 2014			Adjusted December 31, 2014	Effect of Change
Inventory, net	$	104,063	$	97,567	$	(6,496)
Total current assets		185,135		178,639		(6,496)
Total assets		227,654		221,158		(6,496)
Accumulated deficit		(350,887)		(357,383)		(6,496)
Total stockholders' equity		168,352		161,856		(6,496)
Total liabilities and stockholders' equity	$	227,654	$	221,158	$	(6,496)

7

This error was associated with transactions occurring prior to September 2010, at which time the Company revised its methodology to compute and eliminate intercompany profits. However, the Company failed to identify and record an entry to eliminate the cumulative error resulting from the prior methodology. This $6.5 million error resulted in an overstatement of inventory and a cumulative understatement of cost of product revenue as of September 2010.  Thereafter, the effect was an overstatement of inventory and understatement of accumulative deficit for each subsequent reporting period.  The consolidated balance sheets as of December 31, 2015 and 2014 have been revised to reflect the correction of the error through a decrease in inventory and an increase in accumulated deficit of $6.5 million.  In the opinion of management, the effect is not material to the consolidated financial position or results of operations for any previously reported period.  However, prior year amounts will be revised, as reflected above, in future filings.

Note 3. 1-for-4 Reverse Stock Split 

As of 6:00 PM Eastern Time on June 30, 2016, the Company effected a 1-for-4 reverse stock split of its common stock. The Company continues to be traded under its unchanged symbol “ACLS.” All previously reported common stock share amounts in the accompanying financial statements and related notes have been retroactively adjusted to reflect the reverse stock split. As a result of the reduced number of shares outstanding after the reverse stock split, the stated capital attributable to common stock on the Company’s balance sheet (which consists of the unchanged $0.001 par value per share multiplied by the aggregate number of shares issued and outstanding), has been reduced. Correspondingly, the Company’s additional paid-in capital account, which consists of the difference between its stated capital and the aggregate amount paid to the Company upon issuance of all currently outstanding shares of its common stock, has been credited with the amount by which the stated capital was reduced. The Company’s stockholders’ equity, in the aggregate, remains unchanged.

Immediately prior to the effectiveness of the reverse stock split, the Company retired 120,000 shares of common stock held in treasury to the status of authorized and unissued.

Note 4.  Stock-Based Compensation

The Company maintains the Axcelis Technologies, Inc. 2012 Equity Incentive Plan (the “2012 Equity Plan”), which became effective on May 2, 2012, and permits the issuance of options, restricted stock, restricted stock units and performance awards to selected employees, directors and consultants of the Company. The Company’s 2000 Stock Plan (the “2000 Stock Plan”), expired on May 1, 2012 and no new grants may be made under that plan after that date.  However, unexpired awards granted under the 2000 Stock Plan remain outstanding and subject to the terms of the 2000 Stock Plan. The Company also maintains the Axcelis Technologies, Inc. Employee Stock Purchase Plan (the “ESPP”), an Internal Revenue Code Section 423 plan.

The 2012 Equity Plan and the ESPP are more fully described in Note 14 to the consolidated financial statements in the Company’s 2015 Annual Report on Form 10-K.

The Company recognized stock-based compensation expense of $1.9 million and $1.4 million for the three month periods ended September 30, 2016 and 2015, respectively. The Company recognized stock-based compensation expense of $3.9 million and $4.5 million for the nine month periods ended September 30, 2016 and 2015, respectively.  These amounts include compensation expense related to restricted stock units, non-qualified stock options and stock to be issued to participants under the ESPP.

In the three month and nine month periods ended September 30, 2016, the Company issued 0.2 million and 0.4 million shares of common stock, respectively, in connection with the exercise of stock options, resulting in proceeds of $1.2 million and $1.7 million, respectively.

Note 5.  Computation of Net Earnings per Share

Basic earnings per share is computed by dividing income available to common stockholders (the numerator) by the weighted‑average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased by the number of additional common shares that would have been outstanding if the potentially dilutive common shares issuable for stock options, restricted stock units and employee stock purchase plan accounts had been issued, calculated using the treasury stock method. The earnings per share amounts presented within our financial statements and related notes and the related basic and diluted weighted average share amounts stated below have been revised to reflect the 1-for-4 reserve stock split described in Note 3 above.

The components of net earnings per share are as follows:

	Three months ended  September 30,				Nine months ended September 30,
	2016		2015		2016		2015
	(in thousands, except per share data)
Net income available to common stockholders	$	2,151	$	6,101	$	7,036	$	13,852
Weighted average common shares outstanding used in computing basic earnings per share		29,221		28,700		29,118		28,480
Incremental options and RSUs		1,816		1,766		1,642		1,675
Weighted average common shares outstanding used in computing diluted net earnings per share		31,037		30,466		30,760		30,155
Net earnings per share
Basic	$	0.07	$	0.21	$	0.24	$	0.49
Diluted	$	0.07	$	0.20	$	0.23	$	0.46

Diluted weighted average common shares outstanding does not include options and restricted stock units outstanding to purchase 0.9 million and 0.9 million common equivalent shares for the three month periods ended September 30, 2016 and 2015, respectively, and does not include options and restricted stock units outstanding to purchase 0.9 million and 1.0 million common equivalent shares for the nine month periods ended September 30, 2016 and 2015, respectively, as their effect would have been anti-dilutive.

Note 6.  Accumulated Other Comprehensive Income (Loss)

The following table presents the changes in accumulated other comprehensive income (loss), net of tax, by component for the nine months ended September 30, 2016:

	Foreign		Defined benefit
	currency		pension plan		Total
	(in thousands)
Balance at December 31, 2015	$	(744)	$	(687)	$	(1,431)
Other comprehensive income and pension reclassification (1)		1,529		78		1,607
Balance at September 30, 2016	$	785	$	(609)	$	176

(1) The tax effect for pension reclassification was not material to the consolidated financial statements.

Note 7.  Inventories, net

The components of inventories are as follows:

	September 30,		December 31,
	2016		2015
	(in thousands)
Raw materials	$	77,498	$	72,070
Work in process		30,903		29,219
Finished goods (completed systems)		8,600		8,119
	$	117,001	$	109,408

The value of raw materials shown for December 31, 2015, reflects the correction of an immaterial error discussed in Note. 2.

When recorded, inventory reserves are intended to reduce the carrying value of inventories to their net realizable value. The Company establishes inventory reserves when conditions exist that indicate inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand for the Company’s products or market conditions. The Company regularly evaluates the ability to realize the value of inventories based on a combination of factors including the following: forecasted sales or usage, estimated product end of life dates, estimated current and future market value and new product introductions. Purchasing and usage alternatives are also explored to mitigate inventory exposure. As of September 30, 2016 and December 31, 2015, inventories are stated net of inventory reserves of $9.4 million and $10.5 million, respectively.

Note 8.  Product Warranty

The Company generally offers a one year warranty for all of its systems, the terms and conditions of which vary depending upon the product sold. For all systems sold, the Company accrues a liability for the estimated cost of standard warranty at the time of system shipment and defers the portion of systems revenue attributable to the fair value of non-standard warranty. Costs for non-standard warranty are expensed as incurred. Factors that affect the Company’s warranty liability include the number of installed units, historical and anticipated product failure rates, material usage and service labor costs. The Company periodically assesses the adequacy of its recorded liability and adjusts the amount as necessary.

The changes in the Company’s standard product warranty liability are as follows:

	Nine months ended
	September 30,
	2016		2015
	(in thousands)
Balance at January 1 (beginning of year)	$	3,555	$	1,526
Warranties issued during the period		2,286		3,543
Settlements made during the period		(3,570)		(1,611)
Changes in estimate of liability for pre-existing warranties during the period		551		345
Balance at September 30 (end of period)	$	2,822	$	3,803
Amount classified as current	$	2,597	$	3,532
Amount classified as long-term		225		271
Total warranty liability	$	2,822	$	3,803

Note 9.  Restructuring Charges

In the first quarter of 2016, due to changes in customer service contracts resulting from a consolidation in our customer base, the Company had severance and other costs related to a reduction in force. Changes in the Company’s restructuring liability, which consist primarily of payments made on obligations of severance and related costs (which obligations are included in amounts reported as other current liabilities), are as follows:

	(in thousands)
Balance at December 31, 2015	$	—
Severance and, related costs		282
Cash payments		(267)
Balance at September 30, 2016	$	15

Note 10.  Fair Value Measurements

Certain of the assets and liabilities on the Company’s balance sheets are reported at their “fair value.” Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

(a)  Fair Value Hierarchy

The accounting guidance for fair value measurement requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

Level 1 - applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2 - applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3 - applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

(b)  Fair Value Measurements

The Company’s money market funds are included in cash and cash equivalents in the consolidated balance sheets and are considered a level 1 investment as they are valued at quoted market prices in active markets. The Company’s sale leaseback obligation relating to the sale of our corporate headquarters is carried at amortized cost, which approximates fair value based on an implied borrowing rate of 10.65%. The underlying cash flow associated with our lease payments is being applied to both an interest and principal component using the effective interest method over the associated lease term. The liability is categorized as level 3 within the fair value hierarchy.

The following table sets forth the Company’s assets and liabilities by level within the fair value hierarchy:

Note 11.  Financing Arrangements

Sale Leaseback Obligation

On January 30, 2015, the Company sold its corporate headquarters facility to Beverly Property Owner LLC, an affiliate of Middleton Partners, based in Northbrook, Illinois, for the purchase price of $48.9 million. As part of the sale, the Company also entered into a 22-year lease agreement with Beverly Property Owner LLC. The sale leaseback is accounted for as a financing arrangement for financial reporting and, as such, the Company has recorded a financing obligation of $47.6 million as of September 30, 2016. The associated lease payments are deemed to include both an interest component and payment of principal, with the underlying liability being extinguished at the end of the original lease term. The Company posted a collateralized security deposit of $5.9 million in the form of an irrevocable letter of credit at the time of the closing. This letter of credit is cash collateralized and is classified as restricted cash as of September 30, 2016.

Note 12.  Income Taxes

Income tax expense relates principally to operating results of foreign entities in jurisdictions, primarily in Europe and Asia, where the Company earns taxable income. The Company has significant net operating losses in the United States and certain other tax jurisdictions and, as a result, does not pay significant income taxes in those jurisdictions.

At December 31, 2015, the Company had $124.2 million of deferred tax assets worldwide relating to net operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income taxes in future years. The Company maintains a 100% domestic valuation allowance, reducing the carrying value of the deferred tax assets in the United States to zero.  The Company will continue to maintain a full valuation allowance

12

for those tax assets until accounting principles require the release of the allowance based on expectations of continuing profitability.

During the first quarter of 2016, the statute of limitations associated with a tax position previously taken by the Company expired. The related tax reserve of $0.6 million and accrued interest of $0.3 million that had been recorded were reversed during the nine months ended September 30, 2016.

See Note 15 for the effect of the adoption of Accounting Standards Update No. 2015-17.

Note 13.  Concentration of Risk

For the three months ended September 30, 2016, three customers accounted for 16.0%, 12.0% and 11.7% of consolidated revenue, respectively. For the nine months ended September 30, 2016, two customers accounted for 12.3% and 10.1% of total revenue, respectively.

For the three months ended September 30, 2015, two customers accounted for 32.8% and 16.1%, of consolidated revenue, respectively. For the nine months ended September 30, 2015, one customer accounted for 33.0% of consolidated revenue.

At September 30, 2016, two customers accounted for 27.0% and 16.0% consolidated accounts receivable, respectively. At December 31, 2015, three customers accounted for 22.9%, 12.7% and 11.6% of accounts receivable, respectively.

Note 14.  Contingencies

(a)  Litigation

The Company is, from time to time, a party to litigation that arises in the normal course of its business operations. The Company is not presently a party to any litigation that it believes might have a material adverse effect on its business operations.

(b)  Indemnifications

The Company’s system sales agreements typically include provisions under which the Company agrees to take certain actions, provide certain remedies and defend its customers against third-party claims of intellectual property infringement under specified conditions and to indemnify customers against any damage and costs awarded in connection with such claims. The Company has not incurred any material costs as a result of such indemnifications and has not accrued any liabilities related to such obligations in the accompanying consolidated financial statements.

Note 15.  Recent Accounting Guidance

Accounting Standards or Updates Recently Adopted

In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” The amendments in this ASU require entities that present classified statements of financial position to classify deferred tax liabilities and assets as noncurrent. They apply to all entities that present a classified statement of financial position. For public business entities, the amendments in this ASU are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company adopted ASU No. 2015-17 

13

early, effective June 30, 2016, on a prospective basis.  As a result, we have presented all deferred tax assets and liabilities as noncurrent on our consolidated balance sheet as of September 30, 2016, reducing current deferred tax assets by $0.2 million, long-term deferred tax assets by $0.3 million and short-term deferred tax liabilities by $0.5 million. The current deferred tax assets and liabilities on our consolidated balance sheet as of December 31, 2015, have not been reclassified.  

Accounting Standards or Updates Not Yet Effective

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers” (Topic 606): Identifying Performance Obligations and Licensing, which further clarifies performance obligations in a contract with a customer. In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers” (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides a more narrow interpretation of ASU No. 2014-09. These ASUs are effective for annual reporting periods beginning after December 15, 2017 and interim periods within those annual periods. We are currently assessing the potential impact the adoption of these standards will have on our financial statements.

In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory,” which changes the inventory measurement principles for entities using the first-in, first-out (FIFO) or average cost methods. For entities utilizing one of these methods, the inventory measurement principle will change from lower of cost or market to the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the reasonably predictable costs of completion, disposal and transportation. The amendments are effective for annual and interim periods beginning after December 15, 2016. The adoption of this ASU will not have a material impact on our financial statements and disclosures.

In February 2016, the FASB issued ASU No. 2016-02 “Leases.” The ASU requires lessees to recognize the rights and obligations created by most leases as assets and liabilities on their balance sheet and continue to recognize expenses on their income statement over the lease term. It will also require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted for all entities. We are currently evaluating the impact of ASU 2016-02 on the consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU No. 2016-09 “Compensation — Stock Compensation,” which changes the accounting for stock-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for all entities and any entity that elects early adoption must adopt all of the amendments in the same period.  The adoption of this ASU will not have a material impact on our financial statements and disclosures.

Overview

Axcelis is a worldwide producer of ion implantation and other processing equipment used in the fabrication of semiconductor chips in the United States, Europe and Asia.  In addition, the Company provides extensive aftermarket service and support, including spare parts, equipment upgrades and maintenance services to the semiconductor industry worldwide.  Consolidation and partnering within the semiconductor manufacturing industry has resulted in a small number of customers representing a substantial portion of our business.  Our ten largest customers accounted for 69.0% of total revenue for the nine months ended September 30, 2016.

Our product development and manufacturing activities occur primarily in the United States.  Axcelis’ equipment and service products are highly technical and are sold primarily through a direct sales force in the United States, Europe and Asia.

Demand for semiconductor manufacturing equipment and services has historically been subject to cyclical industry conditions reflecting our customers’ responses to changes in the nature and timing of technological advances in fabrication processes, supply and demand for chips, and global economic and market conditions. Separately from overall market demand, Axcelis’ results are also impacted by our customers’ decisions to purchase our products rather than our competitors’ systems. Our financial results in 2015 reflected increased sales of our innovative Purion ion implantation systems over 2014. Purion sales in the first three quarters of 2016 as compared to the same period in 2015 have declined as a result of a decrease in purchasing by dynamic random access memory (DRAM) sector customers. In 2015 and throughout 2016, we have continued to invest in research and development programs related to our Purion products. We expect to continue to grow Purion system sales, gain market share and improve gross margins.   

In light of these conditions, Axcelis' results can vary significantly year-over-year, as well as quarter-over-quarter.  

Critical Accounting Estimates

Management’s discussion and analysis of our financial condition and results of operations included herein and in our Annual Report on Form 10-K for the year ended December 31, 2015 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, revenue and expenses and related disclosure of contingent assets and liabilities. On an on-going basis, we evaluate our estimates and assumptions. 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.

15

Management has not identified any need to make any material change in, and has not changed, any of our critical accounting estimates and judgments as described in Management’s Discussion and Analysis of Financial Conditions and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2015.

Three Months Ended September 30, 2016 Compared with Three Months Ended September 30, 2015

Product

Product revenue, which includes system sales, sales of spare parts, product upgrades and used systems was $59.3 million, or 90.3%, of revenue during the three months ended September 30, 2016, compared with $73.8 million, or 93.0% of revenue for the three months ended September 30, 2015. The $14.5 million decrease in product revenue for the three month period ending September 30, 2016, in comparison to the same period in 2015, was primarily driven by a decrease in the number of Purion systems sold.

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 September 30, 2016 and December 31, 2015 was $7.9 million and $8.5 million, respectively. The decrease is in deferred revenue is primarily due to the timing of the acceptance of system sales.

Services

Services revenue, which includes the labor component of maintenance and service contracts and fees for service hours provided by on-site service personnel, was $6.3 million, or 9.7% of revenue for the three months ended September 30, 2016, compared with $5.5  million, or 7.0% of revenue for the three months ended September 30, 2015. Although services revenue typically increases 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.

Nine Months Ended September 30, 2016 Compared with Nine Months Ended September 30, 2015

Product

Product revenue was $180.3 million, or 91.3% of revenue for the nine months ended September 30, 2016, compared with $214.1 million, or 92.7% of revenue for the nine months ended September 30, 2015. The $33.7 million decrease in product revenue was primarily driven by a decrease in the number of Purion systems sold.    

Services

Services revenue was $17.3 million, or 8.7% of revenue for the nine months ended September 30, 2016, compared with $17.0 million, or 7.3% of revenue for the nine months ended September 30, 2015. 

Revenue Categories used by Management

As an alternative to the line item revenue categories discussed above, management also uses revenue categorizations which divide revenue into new systems sales and “aftermarket,” meaning sales of spare parts, product upgrades and used systems, combined with the sale of maintenance labor and service contracts and services hours.

Three Months Ended September 30, 2016 Compared with Three Months Ended September 30, 2015

Systems

Included in total revenue of $65.7 million during the three months ended September 30, 2016 is revenue from sales of new systems of $30.9 million, or 47.1% of total revenue, compared with $47.0 million, or 59.3%, of total revenue for the three months ended September 30, 2015. The decrease was due to lower sales of our Purion systems sold in the recent quarter.

17

Aftermarket

Included in total revenue of $65.7 million during the three months ended September 30, 2016 is revenue from our aftermarket business of $34.8 million, compared to $32.3 million for the three months ended September 30, 2015. Aftermarket revenue fluctuates from period to period based on capacity utilization at customers’ manufacturing facilities, which affects the sale of spare parts and demand for equipment service.  Aftermarket revenue can also fluctuate from period to period based on the demand for system upgrades or used tools.

Nine Months Ended September 30, 2016 Compared with Nine Months Ended September 30, 2015

Systems

Included in total revenue of $197.6 million during the nine months ended September 30, 2016 is revenue from sales of new systems of $101.6 million, or 51.4% of total revenue, compared with $131.1 million, or 56.7% of total revenue of $231.0 million for the nine months ended September 30, 2015. The decrease was due to lower sales of our Purion systems in the recent period.

Aftermarket

Included in total revenue of $197.6 million during the nine months ended September 30, 2016 is revenue from our aftermarket business of $96.0 million, or 48.6%, compared to $99.9 million, or 43.3% for the nine months ended September 30, 2015.

Three Months Ended September 30, 2016 Compared with Three Months Ended September 30, 2015

Product

Gross margin from product revenue was 38.7% for the three months ended September 30, 2016, compared to 38.1% for the three months ended September 30, 2015. The increase in gross margin of 0.6 percentage points resulted from improved margins on Purion systems combined with an increased mix of higher margin parts and upgrades.

18

Services

Gross margin from services revenue was 18.3% for the three months ended September 30, 2016, compared to 19.6% for the three months ended September 30, 2015. The decrease in gross margin in the recent period is attributable to changes in the mix of service contracts compared with the prior period.

Nine Months Ended September 30, 2016 Compared with Nine Months Ended September 30, 2015

Product

Gross margin from product revenue was 38.3% for the nine months ended September 30, 2016, compared to 35.8% for the nine months ended September 30, 2015.  The increase in gross margin of 2.5 percentage points resulted from improved margins on Purion systems, combined with an increased mix of higher margin parts and upgrades.

Services

Gross margin from services revenue was 20.7% for the nine months ended September 30, 2016, compared to 18.3% for the nine months ended September 30, 2015. The increase in gross margin in the recent period is attributable to an increased share of higher margin service revenue compared with the prior period and lower service costs.

Percentage of revenue		31.1	%		27.1	%						31.3	%		26.6	%

Our operating expenses consist primarily of personnel costs, including salaries, commissions, expected incentive plan payouts, stock-based compensation and related benefits and taxes; project material costs related to the design and development of new products and enhancement of existing products; and professional fees, travel and depreciation expenses.

Personnel costs, exclusive of our restructuring charge, are our largest expense, representing $12.1 million and $35.3 million, or 59.1% and 57.0%, of our total operating expenses for the three and nine month periods ended September 30, 2016, respectively. For the three and nine month periods ended September 30, 2015, personnel costs were $13.2 million and $36.4 million, respectively, or 61.4% and 59.3%, respectively, of our total operating expenses. The lower personnel costs for the three and nine months ended September 30, 2016 are primarily due to lower incentive based pay expense.

Our general and administrative expenses result primarily from the costs associated with our executive, finance, information technology, legal and human resource functions.

Three Months Ended September 30, 2016 Compared with Three Months Ended September 30, 2015

General and administrative expense was $6.0 million during the three months ended September 30, 2016; a decrease of $0.6 million, or 9.1%, compared to $6.6 million during the three months ended September 30, 2015.  The decrease is primarily due to a reduction in incentive plan expense.

Nine Months Ended September 30, 2016 Compared with Nine Months Ended September 30, 2015

General and administrative expense was $18.3 million during the nine months ended September 30, 2016, a decrease of $0.6 million, or 3.5%, compared to $18.9 million during the nine months ended September 30, 2015.  The decrease is primarily due to a reduction in incentive plan expense.

Percentage of revenue		(2.0)	%		(1.8)	%						(2.0)	%		(1.8)	%

Other (expense) income consists primarily of foreign exchange gains and losses attributable to fluctuations against local currencies of the countries in which we operate, interest earned on our invested cash balances, bank fees associated with our financing arrangements and interest expense related to financing arrangements. Other expense was $1.3 million for the three months ended September 30, 2016, relatively flat compared with $1.4  million for the three months ended September 30, 2015. During both of the three month periods ended September 30, 2016 and 2015, the

21

Company recorded $1.3 million in deemed interest expense associated with the sale leaseback of our headquarters in Beverly, which is being accounted for as a financing obligation.

Other expense was $3.9 million for the nine months ended September 30, 2016, compared to $4.2 million for the nine months ended September 30, 2015. The $0.3 million decrease in other expense in the current period was primarily due to an expense in 2015 for the prepayment charge associated with the satisfaction of a term loan.

During the three and nine month periods ended September 30, 2016 and 2015, with the exception of operating lease agreements entered into by the Company, we had no significant off-balance-sheet risk such as exchange contracts, option contracts or other foreign hedging arrangements.

Percentage of revenue		0.2	%			0.2	%						(0.1)	%			0.1	%

We incur income tax expense relating principally to operating results of foreign entities in Europe and Asia, where we earn taxable income. We have significant net operating loss carryforwards in the United States and certain European tax jurisdictions and, as a result, we do not currently pay significant income taxes in those jurisdictions. Additionally, we do not recognize the tax benefit for such losses in the United States and certain European taxing jurisdictions, and will not do so until we have sufficient income such that these tax benefits can be utilized. The Company will continue to maintain a full valuation allowance for these tax assets until accounting principles require the release of the allowance based on expectations of continuing profitability.

During the first quarter of 2016, the statute of limitations associated with a tax position previously taken by the Company expired. The related tax reserve of $0.6 million and accrued interest of $0.3 million that had been recorded were reversed during the nine months ended September 30, 2016.

Liquidity and Capital Resources

The Company had $65.6 million in unrestricted cash and cash equivalents at September 30, 2016, in addition to $6.9 million in restricted cash, primarily comprised of the $5.9 million security deposit under the lease on our headquarters. Management believes that maintaining a strong cash balance is necessary to provide funding for potential ramps in our business, which can require significant cash investment to meet sudden demand.

Our liquidity is affected by many factors.  Some of these relate specifically to the operations of our business, for example, the rate of sale of our products, and others relate to the uncertainties of global economies, including the availability of credit and the condition of the overall semiconductor equipment industry. Our established cost structure, other than cost of goods sold, does not vary significantly with changes in volume. We experience fluctuations in operating results and cash flows depending on these factors.

During the nine months ended September 30, 2016, the Company used $13.0 million of cash in operating activities. This use of cash was predominately driven by system orders from customers and is reflected in increases in accounts receivable, inventories and other assets and liabilities as well as  an increase to accounts payable over the period. In comparison, during the nine months ended September 30, 2015, the Company generated $12.4 million of cash from operating activities.

Investing activities for the nine months ended September 30, 2016 and 2015 generated cash outflows of $2.3 million and $1.3 million, respectively, used for capital expenditures.

22

Financing activities for the nine months ended September 30, 2016 provided net cash of $1.7 million, primarily relating to the proceeds from the exercise of stock options. In comparison, financing activities for the nine months ended September 30, 2015 provided net cash of $37.7 million, primarily due to a net cash inflow of $48.5 million from the sale and leaseback of our corporate headquarters building in Beverly, Massachusetts. This cash inflow from the sale and leaseback was reduced by $0.8 million of related financing costs and the $14.5 million discharge of a term loan secured by a mortgage on the property. Cash provided by financing activities in the nine month period of 2015 also included $3.8 million in proceeds from the exercise of stock options and from stock purchases under the Employee Stock Purchase Plan as well as a $0.8 million decrease in our restricted cash balance. 

We believe that based on our current market, revenue, expense and cash flow forecasts, our existing cash and cash equivalents will be sufficient to satisfy our anticipated cash requirements for the short and long-term. We currently have no credit facility but management believes we would be able to borrow on reasonable terms if needed.

Commitments and Contingencies

Significant commitments and contingencies at September 30, 2016 are consistent with those discussed in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Note 17 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015.

As of September 30, 2016, there have been no material changes to the quantitative information about market risk disclosed in Item 7A to our annual report on Form 10-K for the year ended December 31, 2015.

Correction of Accounting Error in Prior Period

Note 2.  Correction of Accounting Error in Prior Period

Subsequent to March 31, 2016, but prior to filing the Form 10-Q for the quarter ended June 30, 2016, the Company discovered a cumulative error associated with the elimination of profits on sales of inventory to its subsidiaries.  This error had no impact upon the Company’s consolidated statement of operations or consolidated statement of cash flows subsequent to the year ended December 31, 2010.  The following financial statement line items reported in the Company’s consolidated balance sheets for the years ended December 31, 2015 and 2014 were affected by the correction of this accounting error:

(in thousands)	Previously Reported December 31, 2015			Adjusted December 31, 2015	Effect of Change

Inventory, net	$	104,063	$	97,567	$	(6,496)
Total current assets		185,135		178,639		(6,496)

Accumulated deficit		(350,887)		(357,383)		(6,496)

Total liabilities and stockholders' equity	$	227,654	$	221,158	$	(6,496)

This error was associated with transactions occurring prior to September 2010, at which time the Company revised its methodology to compute and eliminate intercompany profits. However, the Company failed to identify and record an entry to eliminate the cumulative error resulting from the prior methodology. This $6.5 million error resulted in an overstatement of inventory and a cumulative understatement of cost of product revenue as of September 2010.  Thereafter, the effect was an overstatement of inventory and understatement of accumulative deficit for each subsequent reporting period.  The consolidated balance sheets as of December 31, 2015 and 2014 have been revised to reflect the correction of the error through a decrease in inventory and an increase in accumulated deficit of $6.5 million.  In the opinion of management, the effect is not material to the consolidated financial position or results of operations for any previously reported period.  However, prior year amounts will be revised, as reflected above, in future filings.

1-for-4 Reverse Stock Split

Note 3. 1-for-4 Reverse Stock Split

As of 6:00 PM Eastern Time on June 30, 2016, the Company effected a 1-for-4 reverse stock split of its common stock. The Company continues to be traded under its unchanged symbol “ACLS.” All previously reported common stock share amounts in the accompanying financial statements and related notes have been retroactively adjusted to reflect the reverse stock split. As a result of the reduced number of shares outstanding after the reverse stock split, the stated capital attributable to common stock on the Company’s balance sheet (which consists of the unchanged $0.001 par value per share multiplied by the aggregate number of shares issued and outstanding), has been reduced. Correspondingly, the Company’s additional paid-in capital account, which consists of the difference between its stated capital and the aggregate amount paid to the Company upon issuance of all currently outstanding shares of its common stock, has been credited with the amount by which the stated capital was reduced. The Company’s stockholders’ equity, in the aggregate, remains unchanged.

Immediately prior to the effectiveness of the reverse stock split, the Company retired 120,000 shares of common stock held in treasury to the status of authorized and unissued.

The Company maintains the Axcelis Technologies, Inc. 2012 Equity Incentive Plan (the “2012 Equity Plan”), which became effective on May 2, 2012, and permits the issuance of options, restricted stock, restricted stock units and performance awards to selected employees, directors and consultants of the Company. The Company’s 2000 Stock Plan (the “2000 Stock Plan”), expired on May 1, 2012 and no new grants may be made under that plan after that date.  However, unexpired awards granted under the 2000 Stock Plan remain outstanding and subject to the terms of the 2000 Stock Plan. The Company also maintains the Axcelis Technologies, Inc. Employee Stock Purchase Plan (the “ESPP”), an Internal Revenue Code Section 423 plan.

The 2012 Equity Plan and the ESPP are more fully described in Note 14 to the consolidated financial statements in the Company’s 2015 Annual Report on Form 10-K.

The Company recognized stock-based compensation expense of $1.9 million and $1.4 million for the three month periods ended September 30, 2016 and 2015, respectively. The Company recognized stock-based compensation expense of $3.9 million and $4.5 million for the nine month periods ended September 30, 2016 and 2015, respectively.  These amounts include compensation expense related to restricted stock units, non-qualified stock options and stock to be issued to participants under the ESPP.

In the three month and nine month periods ended September 30, 2016, the Company issued 0.2 million and 0.4 million shares of common stock, respectively, in connection with the exercise of stock options, resulting in proceeds of $1.2 million and $1.7 million, respectively.

Computation of Net Earnings per Share

Note 5.  Computation of Net Earnings per Share

Basic earnings per share is computed by dividing income available to common stockholders (the numerator) by the weighted‑average number of common shares outstanding (the denominator) for the period. The computation of diluted earnings per share is similar to basic earnings per share, except that the denominator is increased by the number of additional common shares that would have been outstanding if the potentially dilutive common shares issuable for stock options, restricted stock units and employee stock purchase plan accounts had been issued, calculated using the treasury stock method. The earnings per share amounts presented within our financial statements and related notes and the related basic and diluted weighted average share amounts stated below have been revised to reflect the 1-for-4 reserve stock split described in Note 3 above.

The components of net earnings per share are as follows:

When recorded, inventory reserves are intended to reduce the carrying value of inventories to their net realizable value. The Company establishes inventory reserves when conditions exist that indicate inventory may be in excess of anticipated demand or is obsolete based upon assumptions about future demand for the Company’s products or market conditions. The Company regularly evaluates the ability to realize the value of inventories based on a combination of factors including the following: forecasted sales or usage, estimated product end of life dates, estimated current and future market value and new product introductions. Purchasing and usage alternatives are also explored to mitigate inventory exposure. As of September 30, 2016 and December 31, 2015, inventories are stated net of inventory reserves of $9.4 million and $10.5 million, respectively.

Note 8.  Product Warranty

The Company generally offers a one year warranty for all of its systems, the terms and conditions of which vary depending upon the product sold. For all systems sold, the Company accrues a liability for the estimated cost of standard warranty at the time of system shipment and defers the portion of systems revenue attributable to the fair value of non-standard warranty. Costs for non-standard warranty are expensed as incurred. Factors that affect the Company’s warranty liability include the number of installed units, historical and anticipated product failure rates, material usage and service labor costs. The Company periodically assesses the adequacy of its recorded liability and adjusts the amount as necessary.

Fair Value Measurements

Fair Value Measurements

Fair Value Measurements

Note 10.  Fair Value Measurements

Certain of the assets and liabilities on the Company’s balance sheets are reported at their “fair value.” Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

(a)  Fair Value Hierarchy

The accounting guidance for fair value measurement requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard establishes a fair value hierarchy based on the level of independent, objective evidence surrounding the inputs used to measure fair value. A financial instrument’s categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The fair value hierarchy is as follows:

Level 1 - applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2 - applies to assets or liabilities for which there are inputs other than quoted prices that are observable for the asset or liability, such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3 - applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

(b)  Fair Value Measurements

The Company’s money market funds are included in cash and cash equivalents in the consolidated balance sheets and are considered a level 1 investment as they are valued at quoted market prices in active markets. The Company’s sale leaseback obligation relating to the sale of our corporate headquarters is carried at amortized cost, which approximates fair value based on an implied borrowing rate of 10.65%. The underlying cash flow associated with our lease payments is being applied to both an interest and principal component using the effective interest method over the associated lease term. The liability is categorized as level 3 within the fair value hierarchy.

The following table sets forth the Company’s assets and liabilities by level within the fair value hierarchy:

	September 30, 2016
	Fair Value Measurements
	Level 1		Level 2		Level 3		Total
	(in thousands)

(c)  Other Financial Instruments

The carrying amounts reflected in the consolidated balance sheets for cash and cash equivalents (which are comprised primarily of deposit and investment accounts), accounts receivable, prepaid expenses and other current and non-current assets, accounts payable and accrued expenses approximate fair value due to their short-term maturities.

On January 30, 2015, the Company sold its corporate headquarters facility to Beverly Property Owner LLC, an affiliate of Middleton Partners, based in Northbrook, Illinois, for the purchase price of $48.9 million. As part of the sale, the Company also entered into a 22-year lease agreement with Beverly Property Owner LLC. The sale leaseback is accounted for as a financing arrangement for financial reporting and, as such, the Company has recorded a financing obligation of $47.6 million as of September 30, 2016. The associated lease payments are deemed to include both an interest component and payment of principal, with the underlying liability being extinguished at the end of the original lease term. The Company posted a collateralized security deposit of $5.9 million in the form of an irrevocable letter of credit at the time of the closing. This letter of credit is cash collateralized and is classified as restricted cash as of September 30, 2016.

Income tax expense relates principally to operating results of foreign entities in jurisdictions, primarily in Europe and Asia, where the Company earns taxable income. The Company has significant net operating losses in the United States and certain other tax jurisdictions and, as a result, does not pay significant income taxes in those jurisdictions.

At December 31, 2015, the Company had $124.2 million of deferred tax assets worldwide relating to net operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income taxes in future years. The Company maintains a 100% domestic valuation allowance, reducing the carrying value of the deferred tax assets in the United States to zero.  The Company will continue to maintain a full valuation allowance for those tax assets until accounting principles require the release of the allowance based on expectations of continuing profitability.

During the first quarter of 2016, the statute of limitations associated with a tax position previously taken by the Company expired. The related tax reserve of $0.6 million and accrued interest of $0.3 million that had been recorded were reversed during the nine months ended September 30, 2016.

Accounting Standards or Updates Recently Adopted

In November 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-17, “Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes.” The amendments in this ASU require entities that present classified statements of financial position to classify deferred tax liabilities and assets as noncurrent. They apply to all entities that present a classified statement of financial position. For public business entities, the amendments in this ASU are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The Company adopted ASU No. 2015-17 early, effective June 30, 2016, on a prospective basis. As a result, we have presented all deferred tax assets and liabilities as noncurrent on our consolidated balance sheet as of September 30, 2016, reducing current deferred tax assets by $0.2 million, long-term deferred tax assets by $0.3 million and short-term deferred tax liabilities by $0.5 million. The current deferred tax assets and liabilities on our consolidated balance sheet as of December 31, 2015, have not been reclassified.

Accounting Standards or Updates Not Yet Effective

In May 2014, the FASB issued ASU No. 2014-09, “Revenue from Contracts with Customers,” which provides guidance for revenue recognition. The standard’s core principle is that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In April 2016, the FASB issued ASU 2016-10, “Revenue from Contracts with Customers” (Topic 606): Identifying Performance Obligations and Licensing, which further clarifies performance obligations in a contract with a customer. In May 2016, the FASB issued ASU 2016-12, “Revenue from Contracts with Customers” (Topic 606): Narrow-Scope Improvements and Practical Expedients, which provides a more narrow interpretation of ASU No. 2014-09. These ASUs are effective for annual reporting periods beginning after December 15, 2017 and interim periods within those annual periods. We are currently assessing the potential impact the adoption of these standards will have on our financial statements.

In July 2015, the FASB issued ASU No. 2015-11, “Simplifying the Measurement of Inventory,” which changes the inventory measurement principles for entities using the first-in, first-out (FIFO) or average cost methods. For entities utilizing one of these methods, the inventory measurement principle will change from lower of cost or market to the lower of cost and net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less the reasonably predictable costs of completion, disposal and transportation. The amendments are effective for annual and interim periods beginning after December 15, 2016. The adoption of this ASU will not have a material impact on our financial statements and disclosures.

In February 2016, the FASB issued ASU No. 2016-02 “Leases.” The ASU requires lessees to recognize the rights and obligations created by most leases as assets and liabilities on their balance sheet and continue to recognize expenses on their income statement over the lease term. It will also require disclosures designed to give financial statement users information on the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted for all entities. We are currently evaluating the impact of ASU 2016-02 on the consolidated financial statements and disclosures.

In March 2016, the FASB issued ASU No. 2016-09 “Compensation — Stock Compensation,” which changes the accounting for stock-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted for all entities and any entity that elects early adoption must adopt all of the amendments in the same period.  The adoption of this ASU will not have a material impact on our financial statements and disclosures.
