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 producer of ion implantation and other processing equipment used in the fabrication of semiconductor chips in the United States, Europe and Asia. In addition, we provide extensive worldwide 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, 2018 has been derived from the audited consolidated 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, 2018.

Note 2. Stock-Based Compensation

We maintain 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. Our 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. We also maintain 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 13 to the consolidated financial statements in our 2018 Annual Report on Form 10-K.

We recognized stock-based compensation expense of $2.3 million and $2.1 million for the three month periods ended June 30, 2019 and 2018, respectively. We recognized stock-based compensation expense of $4.0 million and $3.2 million for the six month periods ended June 30, 2019 and 2018, respectively. These amounts include compensation expense related to restricted stock units (“RSUs”), non-qualified stock options and stock to be issued to participants under the ESPP.

In the three month periods ended June 30, 2019 and 2018, we issued 0.3 million and 0.2 million shares of common stock, respectively, upon stock option exercises, purchases under the ESPP and vesting of RSUs. In the three month periods ended June 30, 2019 and 2018, we received proceeds of $1.0 million and $0.9 million, respectively, in connection with the exercise of stock options and ESPP purchases.

In the six month periods ended June 30, 2019 and 2018, we issued 0.6 million and 0.3 million shares of common stock, respectively, upon stock option exercises, purchases under the ESPP and vesting of RSUs. In the six month periods ended June 30, 2019 and 2018, we received proceeds of $2.8 million and $1.3 million, respectively, in connection with the exercise of stock options and ESPP purchases.

Note 3. Leases

We have operating leases for office space, warehouse space, computer and office equipment and vehicles used in our business operations. We have a finance lease in relation to the 2015 sale-leaseback of our corporate headquarters in

Table of Contents

Beverly, Massachusetts. We review all contract agreements to determine if the agreement contains a lease component. An agreement contains a lease component if it provides the use of a specific physical space or a specific physical item. We recognize the lease obligation on a discounted basis using the explicit or implicit discount rate stated within the agreement. For those lease agreements that do not indicate the applicable discount rate, we use the corporate borrowing rate. The value of the right-of-use asset is initially determined based on the net present value of the associated liability, and is adjusted for deferred costs and possible impairments, if any. We have made the following policy elections: (i) operating leases with an initial term of 12 months or less are not recorded on the consolidated balance sheet; (ii) we recognize lease expense for operating leases on a straight-line basis over the lease term; and (iii) we account for lease components and non-lease components that are fixed payments as one component. Some of our operating leases include one or more options to renew, with renewal terms that can extend the respective lease term 1 to 3 years. The exercise of lease renewal options are at our sole discretion. For lease extensions that are reasonably certain to occur, we have included these renewal periods in our calculation of the net present value of the lease obligation and related right-of-use asset. Certain leases also include options to purchase the leased property. The depreciable life of certain assets and leasehold improvements are limited by the expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. The amounts of operating and finance lease right-of-use assets and related lease obligations recorded within our consolidated balance sheet are as follows:

Leases	Classification	June 30, — 2019

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 and RSUs had been issued, calculated using the treasury stock method.

The components of net earnings per share are as follows:

	Three months ended — June 30,		Six months ended — June 30,
	2019	2018	2019	2018
	(in thousands, except per share amounts)
Net income available to common stockholders	$ 556	$ 14,669	$ 6,618	$ 28,584
Weighted average common shares outstanding used in computing basic income per share	32,729	32,214	32,706	32,154
Incremental options and RSUs	1,172	1,728	1,358	1,894
Weighted average common shares used in computing diluted net income per share	33,901	33,942	34,064	34,048

Basic	$ 0.02	$ 0.46	$ 0.20	$ 0.89
Diluted	$ 0.02	$ 0.43	$ 0.19	$ 0.84

Diluted weighted average common shares outstanding does not include options and RSUs outstanding to purchase 0.2 million and 0.3 million common equivalent shares for the three month periods ended June 30, 2019 and 2018, respectively, nor options and RSUs outstanding to purchase ten thousand common equivalent shares for the six month periods ended June 30, 2019 and 2018, respectively, as their effect would have been anti-dilutive.

Note 7. Cash, cash equivalents and restricted cash

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the consolidated balance sheet that sum to the total of the amounts shown in the statement of cash flows.

Total cash, cash equivalents and restricted cash	$ 143,164	$ 184,902

As of June 30, 2019, we had $6.8 million in restricted cash which relates to a $5.9 million letter of credit associated with a security deposit for the lease of our corporate headquarters in Beverly, Massachusetts, a $0.7 million letter of credit relating to workers’ compensation insurance, a bank guarantee of our performance relating to a customer payment in the amount of $0.1 million and a $0.1 million deposit relating to customs activity.

Note 8. Inventories, net

Finished goods (completed systems)	14,412	13,268
Inventories, net	$ 135,141	$ 129,000

When recorded, inventory reserves reduce the carrying value of inventories to their net realizable value. We establish 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. We regularly evaluate 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.

Note 9. Product Warranty

We generally offer a one year warranty for all of our systems, the terms and conditions of which vary depending upon the product sold. For all systems sold, we accrue a liability for the estimated cost of standard warranty at the time of system shipment and defer 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 our warranty liability include the number of installed units, historical and anticipated product failure rates, material usage and service labor costs. We periodically assess the adequacy of our recorded liability and adjust the amount as necessary.

Note 10. Fair Value Measurements

Certain assets on our 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

Our money market funds and short-term investments are included in cash and cash equivalents in the consolidated balance sheets.

Table of Contents

The following table sets forth our assets by level within the fair value hierarchy:

(c) Other Financial Instruments

The carrying amounts reflected in the consolidated balance sheets for accounts receivable, prepaid expenses and other current assets and non-current assets, restricted cash, accounts payable and accrued expenses approximate fair value due to their short-term maturities.

Note 11. Financing Arrangements

On January 30, 2015, we sold our corporate headquarters facility in Beverly Massachusetts for $48.9 million. As part of the sale, we also entered into a 22-year lease agreement of our headquarters facility. This sale leaseback is accounted for as a financing lease under generally accepted accounting principles and, as such, we have recorded a financing obligation of $48.5 million as of June 30, 2019. Our current lease payments are interest only payments. Commencing in April, 2020, the associated lease payments will include both an interest component and payment of principal, with the underlying liability being extinguished at the end of the original lease term. We posted a 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 the associated cash is included in long-term restricted cash.

Note 12. Income Taxes

The income tax provision was $0.8 million during the three months ended June 30, 2019, a decrease of $2.2 million when compared to the three months ended June 30, 2018. The $2.2 million decrease was primarily due to a $3.4 million reduction in tax expense attributable to the decrease in pretax income of $16.3 million, partially offset by a $0.9 million increase in our valuation allowance relating to uncertainty regarding our utilization of research and development credits and $0.3 million of tax benefits relating to stock option exercises and RSU vesting.

The income tax provision was $1.3 million during the six months ended June 30, 2019, a decrease of $5.3 million when compared to the six months ended June 30, 2018. Of the $5.3 million decrease, $5.7 million was attributable to the decrease in pretax income of $27.2 million, offset by $0.4 million primarily related to a decrease in the tax benefits relating to stock option exercises and RSU vesting.

We have significant net operating loss carryforwards in the United States and certain European jurisdictions, and, as a result, we do not currently pay significant income taxes in those jurisdictions. Tax expense reflects the tax liability that would be payable without consideration of the usage of any net operating loss carryforwards. At December 31, 2018, we had $71.9 million of deferred tax assets worldwide comprised of net operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income tax liabilities in future years. This amount was net of

Table of Contents

a $6.8 million valuation allowance. As of June 30, 2019, the valuation allowance increased to $7.7 million due to the uncertainty of the utilization of certain research and development credits.

Note 13. Concentration of Risk

For the three months ended June 30, 2019, four customers accounted for 15.7%, 14.2%, 12.7% and 12.5% of total revenue, respectively. For the three months ended June 30, 2018, one customer accounted for 23.9% of total revenue.

For the six months ended June 30, 2019, four customers accounted for 14.8%, 14.4%, 11.4% and 11.2% of total revenue, respectively. For the six months ended June 30, 2018, two customers accounted for 24.9% and 11.8% of total revenue, respectively.

At June 30, 2019, three customers accounted for 20.2%, 14.3% and 12.2% of accounts receivable, respectively. At December 31, 2018, two customers accounted for 21.9% and 11.5% of accounts receivable, respectively.

Note 14. Share Repurchase

Under the current stock repurchase plan, announced on January 14, 2019, we are authorized to repurchase up to $35 million of our common stock through the end of 2019. During the six months ended June 30, 2019, we purchased 0.9 million shares at an average cost of $15.83 per share. The timing and actual number of shares repurchased will depend on various factors including price, corporate and regulatory requirements, alternative investment opportunities and other market conditions.

Shares repurchased by us are accounted for when the transaction is settled. There were no unsettled share repurchases at June 30, 2019. Shares repurchased and retired are deducted from common stock for par value and from additional paid-in capital for the excess over par value. If additional paid-in capital has been exhausted, the excess over par value is deducted from retained earnings. Direct costs incurred to acquire the shares are included in the total cost of the shares.

Note 15. Contingencies

(a) Litigation

We are, from time to time, a party to litigation that arises in the normal course of our business operations. We are not presently a party to any litigation that we believe might have a material adverse effect on our business operations.

(b) Indemnifications

Our system sales agreements typically include provisions under which we agree to take certain actions, provide certain remedies and defend our 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. We have not incurred any material costs as a result of such indemnifications and have not accrued any liabilities related to such obligations in the accompanying consolidated financial statements.

Note 16. Headcount-related Actions

During the three months ended June 30, 2019, given the industry slowdown, we took steps to reduce expenses through a variety of programs. Headcount–related actions resulted in $1.0 million of additional expense in the quarter ended June 30, 2019. This expense was recorded as follows; $0.5 million to cost of revenue, $0.3 million to research and development and $0.1 million to both sales and marketing and general and administrative, respectively. As of June 30, 2019, all of these expenses remained accrued within current liabilities.

Note 17. Recent Accounting Guidance

(a) Accounting Standards Update 2016-02 on Leases Effective January 1, 2019

We adopted Accounting Standards Update (“ASU”) No. 2016-02, “ Leases” and ASU No. 2018-11 “ Leases (Topic 842)” , collectively (“Topic 842) as of January 1, 2019, using the modified retrospective approach, applying the new lease standard at the adoption date. We elected the package of practical expedients permitted under the transition guidance within the new standard, carrying forward the historical lease classification for both operating and finance leases. We made an accounting policy election to keep leases with an initial term of 12 months or less off of the balance sheet. We recognize the lease expense relating to operating leases on a straight-line basis over the respective lease term and report the associated expense within the operating activities section of our statement of cash flows. We recognize the interest expense on our finance lease within the operating activities section of our statement of cash flows and recognize the payment of principal of our finance lease obligation within the financing activities section of our statement of cash flows.

The adoption of Topic 842 resulted in the recording of additional net operating lease assets and related lease liabilities of $7.5 million as of January 1, 2019. We also reclassified $22.1 million net, of previously capitalized property, plant and equipment associated with the sale of our corporate headquarters, as well as $0.8 million of prepaid transaction costs, as finance lease assets, within our balance sheet. The related finance lease liability associated with the sale-leaseback increased $0.8 million as a result of the reclassification of the prepaid transaction costs. The standard had no impact on our consolidated net earnings and cash flows.

(b) Accounting Standards Update 2018-13 on Fair Value Measurements

We adopted ASU No. 2018-13 “Fair Value Measurement (Topic 820)” as of January 1, 2019, The amendments in ASU No. 2018-13 modify the disclosure requirements on fair value measurements in Topic 820, removing disclosure requirements for transfers between Level 1 and Level 2 within the fair value hierarchy, as well as modifying the disclosure requirement relating to the timing of liquidation for investments calculated on net asset value. The ASU also requires the disclosure of unrealized gains and losses for the period included in other comprehensive income for Level 3 instruments. The amendments on changes for unrealized gains and losses should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. The adoption of ASU 2018-13 did not have any impact on our consolidated financial statements and disclosures.

(c) Accounting Standards Update 2019-04 on Financial Instruments; Topic 326, Topic 815 and Topic 825 to be Effective January 1, 2020

In April 2019, the Financial Accounting Standards Board issued ASU No. 2019-04 “Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging, and Topic 825, Financial Instruments.” The amendments in this Update clarify the guidance within Topic 326 relating to credit losses. The guidance is effective for annual reporting periods beginning after December 15, 2019, and interim periods within those years. Early adoption is permitted in any interim period after issuance of this Update as long as the entity has adopted the amendments in Update 2016-13. The amendments in these Updates should be applied on a modified-retrospective basis by means of a cumulative-effect adjustment to the opening retained earnings balance in the statement of financial position as of the date of adoption of Update 2016-13. The adoption of these Updates is not expected to have a material impact on our results of operations or cash flows.

Overview

We are a producer of ion implantation and other processing equipment used in the fabrication of semiconductor chips in the United States, Europe and Asia. In addition, we provide extensive worldwide aftermarket service and support, including spare parts, equipment upgrades and maintenance services to the semiconductor industry. 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 77.4% of total revenue for the six months ended June 30, 2019.

Our product development and manufacturing activities occur primarily in the United States. Our equipment and service products are highly technical and are sold primarily through a direct sales force in the United States, Europe and Asia. In the first half of 2019, our revenues were adversely affected by the current industry slowdown, but we delivered solid financial performance at the lower revenue level, driven by improved gross margin. Our strong gross margins in the second quarter are the result of margin improvement initiatives and product mix. Given the industry slowdown, we took steps during the quarter to reduce expenses through a variety of programs. Headcount–related actions resulted in $1.0 million of additional expense in the second quarter 2019. We continued to invest in new product extensions during the 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, 2018 are based upon our 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 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.

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, 2018.

Three months ended June 30, 2019 Compared with Three months ended June 30, 2018

Product

Product revenue, which includes systems sales, sales of spare parts, product upgrades and used systems was $68.7 million, or 92.5% of revenue during the three months ended June 30, 2019, compared with $112.5 million, or 94.3% of revenue for the three months ended June 30, 2018. The $43.8 million decrease in product revenue for the three month

Table of Contents

period ending June 30, 2019, in comparison to the same period in 2018, was primarily driven by a decrease in the number of systems sold.

A portion of our revenue from systems sales is deferred until installation and other services related to future performance obligations are performed. The total amount of deferred revenue at June 30, 2019 and December 31, 2018 was $14.1 million and $22.6 million, respectively. The net decrease in deferred revenue is primarily due to the decrease in the number of systems sold and to a lesser extent, the timing of system acceptances.

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 $5.6 million, or 7.5% of revenue for the three months ended June 30, 2019, compared with $6.8 million, or 5.7% of revenue for the three months ended June 30, 2018. 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.

Six months ended June 30, 2019 Compared with Six months ended June 30, 2018

Product

Product revenue, which includes systems sales, sales of spare parts, product upgrades and used systems was $152.9 million, or 92.2% of revenue during the six months ended June 30, 2019, compared with $228.5 million, or 94.6% of revenue for the six months ended June 30, 2018. The $75.6 million decrease in product revenue for the six month period ending June 30, 2019, in comparison to the same period in 2018, was primarily driven by a decrease in the number of systems sold.

Services

Services revenue was $12.9 million, or 7.8% of revenue for the six months ended June 30, 2019, compared with $13.0 million, or 5.4% of revenue for the six months ended June 30, 2018.

Revenue Categories used by Management

In addition to the line item revenue categories discussed above, management also regularly disaggregates revenue in the following categories, which it finds relevant and useful:

· Ion implant revenue separate from revenue from legacy non-implant product lines, given that ion implantation systems are critical to our growth and strategic objectives;

· Systems and aftermarket revenues, in which “Aftermarket” is

A. the portion of Product revenue relating to spare parts, product upgrades and used systems combined with

B. Services revenue, which is the labor component of aftermarket revenues;

Aftermarket purchases reflect current fab utilization as opposed to Systems purchases which reflect capital investment decisions by our customers, which have differing economic drivers;

· Revenue by geographic regions, since economic factors impacting customer purchasing decisions may vary by geographic region; and

· Revenue by our customer market segments, since they can be subject to different economic drivers at different periods of time, impacting a customer’s likelihood of purchasing capital equipment during any particular period. Currently, management references three customer market segments: memory, mature technology processes and leading edge foundry and logic.

Table of Contents

The ion implant and aftermarket revenue categories for recent periods are discussed below.

Three months ended June 30, 2019 Compared with Three months ended June 30, 2018

Ion Implant

Included in total revenue of $74.3 million during the three months ended June 30, 2019 is revenue from sales of ion implant of $70.2 million, or 94.5% of total revenue, compared with $113.6 million, or 95.2%, of total revenue for the three months ended June 30, 2018. The remaining $4.1 million of revenue for the three months ended June 30, 2019 was non-ion implant products and services.

Aftermarket

Included in total revenue of $74.3 million during the three months ended June 30, 2019 is revenue from our aftermarket business of $37.1 million, compared to $45.3 million for the three months ended June 30, 2018. The remaining $37.2 million of revenue for the three months ended June 30, 2019 was from system sales. 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.

Other (expense) income consists primarily of interest relating to the finance lease obligation we incurred in connection with the 2015 sale of our headquarters facility (“sale leaseback)” and other financing obligations, foreign exchange gains and losses attributable to fluctuations of the U.S dollar against local currencies of certain of the countries in which we operate as well as interest earned on our invested cash balances.

Other expense was $0.7 million for the three months ended June 30, 2019, compared with $1.6 million for the three months ended June 30, 2018. The decrease in other expense for the three month period ended June 30, 2019 compared to the three month period ended June 30, 2018, was primarily due to lower foreign currency exchange losses in the current year period compared to the prior year and increased interest earned on our invested cash balances. Other expense was $1.2 million for the six months ended June 30, 2019, compared with $2.7 million for the six months ended June 30, 2018. The decrease in other expense for the six month period ended June 30, 2019 compared to the six month period ended June 30, 2018, was primarily due to lower foreign currency exchange losses in the current year and increased interest earned on our invested cash balances compared to the same period last year.

At December 31, 2018, we had $71.9 million of deferred tax assets worldwide comprised of net operating loss carryforwards, tax credit carryforwards and other temporary differences, which are available to reduce income tax liabilities in future years. This amount was net of a $6.8 million valuation allowance. As of June 30, 2019, the valuation allowance increased to $7.7 million due to the uncertainty of the utilization of certain research and development credits. Management considered the weight of all available evidence in determining whether a valuation allowance was required. After consideration of both positive and negative evidence, management concluded that it is more likely than not that a substantial portion of the Company’s deferred tax assets will be realized. The positive evidence considered was three year U.S. historical cumulative profitability, projected future taxable income and length of carry-forward periods of net operating losses and tax credits. The primary negative evidence considered was the volatility of the semiconductor industry in which we operate.

Liquidity and Capital Resources

We had $136.3 million in unrestricted cash and cash equivalents at June 30, 2019, in addition to $6.8 million in restricted cash, primarily comprised of the $5.9 million security deposit for the lease of our corporate 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. Additionally, we have begun efforts to identify both organic and inorganic opportunities to drive future growth, for which cash resources will be necessary.

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 economic conditions, 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. We are also engaging in stock repurchases, as discussed below.

During the six months ended June 30, 2019, we used $20.3 million of cash related to operating activities. This was predominately driven by inventory purchases, payments to our vendors and prior year incentive based pay. In comparison, during the six months ended June 30, 2018, we generated $15.3 million of cash from operations.

Investing activities for the six months ended June 30, 2019 and 2018 resulted in cash outflows of $8.8 million and $1.7 million, respectively, used for capital expenditures.

Financing activities for the six months ended June 30, 2019 used net cash of $12.8 million, $14.0 million of which related to the repurchase of our common stock and $1.6 million related to the payments made to government tax authorities for income tax withholding on RSU vesting, where shares are withheld by the Company. These amounts were partially offset by $2.8 million of proceeds related to the exercise of stock options and purchase of shares under our ESPP. Financing

Table of Contents

activities for the six months ended June 30, 2018 used net cash of $0.1 million, of which $1.4 million related to payments made to government tax authorities for income tax withholding on RSU vesting, where shares are withheld by the Company the proceeds from the exercise of stock options, partially offset by $1.3 million related to the exercise of stock options and issuance of shares under our ESPP.

We believe that based on our current market, revenue, expense and cash flow forecasts, our existing cash, cash equivalents and borrowing capacity 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.

On January 14, 2019 we announced that our Board of Directors authorized a one-year share repurchase program of up to $35 million of our common stock. These shares may be purchased in the open market or through privately negotiated transactions. We commenced repurchases of our stock in the quarter ended June 30, 2019, using $14.0 million in cash for this purpose. As of June 30, 2019, we had approximately $21.0 million remaining under the share repurchase program. See Part II of this report. We have no obligation to repurchase any additional shares under the authorization, and the timing, actual number and value of shares which are repurchased will depend on a number of factors, including the price of our common stock, general business and market conditions, and alternative investment opportunities. We may suspend or discontinue the repurchase program at any time.
