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 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, 2020 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, 2020.

Note 2. Stock-Based Compensation

We maintain the Axcelis Technologies, Inc. 2012 Equity Incentive Plan, as amended (the “2012 Equity Plan”), which became effective on May 2, 2012, and permits the issuance of options, restricted stock, restricted stock units (“RSUs”) 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 options granted under the 2000 Stock Plan, which have a 10-year term, remain outstanding and subject to the terms of the 2000 Stock Plan. We also maintain the Axcelis Technologies, Inc. 2020 Employee Stock Purchase Plan (the “2020 ESPP”), an Internal Revenue Code Section 423 plan.

The 2012 Equity Plan is more fully described in Note 13 to the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2020.

We recognized stock-based compensation expense of $2.4 million and $1.7 million for the three-month periods ended March 31, 2021 and 2020, respectively. These amounts include compensation expense related to RSUs and non-qualified stock options.

In the three-month periods ended March 31, 2021 and 2020, we issued 0.3 million and 0.6 million shares of common stock, respectively, upon stock option exercises and vesting of RSUs. In the three-month periods ended March 31, 2021 and 2020, we received proceeds of $2.5 million and $4.5 million, respectively, in connection with the exercise of stock options.

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 as a result of the 2015 sale-leaseback of our corporate headquarters in Beverly, Massachusetts. All new agreements are reviewed to determine if they contain a lease component. A lease is a contract or part of a contract that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. We recognize the lease obligation on a discounted basis using the explicit or implicit discount rate stated within the agreement. We recognize a corresponding right-of-use asset, which is initially determined based upon the net present value of the associated liability and is adjusted for deferred costs and possible impairment, if

Table of Contents

any. For those lease agreements that do not indicate the applicable discount rate, we use our incremental borrowing rate. 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 is 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 sheets are as follows:

Finance lease assets are recorded net of accumulated depreciation of $48.4 million and include $0.7 million of prepaid financing costs as of December 31, 2020.

All of our operating lease office locations support selling and servicing functions. Operating lease expense, and depreciation and interest expense relating to our finance lease obligation, are recognized within our consolidated statement of operations for the three months ended March 31, 2021 and 2020 as follows:

Note 4. Revenue

To reflect the organization of our business operations, we divide revenue into two categories: revenue from sales of new systems and revenue arising from the sale of used systems, parts and labor to customers who own systems, which we refer to as “Aftermarket.”

Revenue by categories used by management are as follows:

Systems	$	80,991	$	82,338
Aftermarket		51,785		36,653
Total Revenue	$	132,776	$	118,991

We also consider revenue by geography. Revenue is allocated to geographic markets based upon the location to which our products are shipped and in which our services are performed. Revenue in our principal geographic markets is as follows:

Our system sales revenue transactions give rise to contract liabilities (in the case of pre-payments and the fair value of goods and services to be delivered after the system delivery, such as installation and certain warranty obligations).

Contract liabilities are as follows:


	March 31,		December 31,
	2021		2020

	(in thousands)
Contract liabilities	$	22,142	$	23,058

Contract liabilities are reflected as deferred revenue on the consolidated balance sheet and relate to payments invoiced or received in advance of completion of performance obligations under a contract. Contract liabilities are recognized as revenue upon the fulfillment of performance obligations.

The majority of our system transactions have payment terms of 90% due upon shipment of the tool and 10% due upon acceptance. Aftermarket transaction payment terms usually provide that payment is due either within 30 or 60 days after the service is provided or parts delivered.

Note 5. Receivables and Allowances for Credit Losses

All trade receivables are reported on the Consolidated Balance Sheets at their amortized cost adjusted for any write-offs and net of allowances for credit losses.

Axcelis maintains an allowance for credit losses, which represent an estimate of expected losses over the remaining contractual life of its receivables considering current market conditions and estimates for supportable forecasts when appropriate. The estimate is a result of the Company’s ongoing assessments and evaluations of collectability, historical loss experience, and future expectations in estimating credit losses in its receivable portfolio. Axcelis uses historical loss experience rates and applies them to a related aging analysis while also considering customer and/or economic risk where appropriate. Determination of the proper amount of allowances requires management to exercise judgment about the timing, frequency and severity of credit losses that could materially affect the provision for credit losses and, as a result, net earnings. The allowance takes into consideration numerous quantitative and qualitative factors that include receivable type, historical loss experience, loss migration, delinquency trends, collection experience, current economic conditions, estimates for supportable forecasts, when appropriate, and credit risk characteristics.

Axcelis evaluates the credit risk of the customer when extending credit based on a combination of various financial and qualitative factors that may affect its customers’ ability to pay. These factors may include the customer’s financial condition, past payment experience, and credit bureau report, as well as the value of the underlying collateral.

Management performs detailed reviews of Axcelis’ receivables on a quarterly basis to assess the adequacy of the allowances and to determine if any impairment has occurred. Amounts determined to be uncollectable are charged directly against the allowances, while amounts recovered on previously written-off accounts increase the allowances. Changes to the allowances for credit losses are maintained through adjustments to the provision for credit losses, which are charged to current period earnings.

Table of Contents

Note 6. 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 on exercise of stock options and vesting of RSUs had been issued, calculated using the treasury stock method.

The components of net earnings per share are as follows:


	Three months ended
	March 31,
	2021		2020

Net income available to common stockholders	$	16,480	$	11,221
Weighted average common shares outstanding used in computing basic income per share		33,715		32,872
Incremental options and RSUs		928		1,185
Weighted average common shares used in computing diluted net income per share		34,643		34,057
Net income per share
Basic	$	0.49	$	0.34
Diluted	$	0.48	$	0.33

Diluted weighted average common shares outstanding does not include 1,429 and 1,675 common equivalent shares issuable with respect to outstanding equity awards for the three-month periods ended March 31, 2021 and 2020, respectively, as their effect would have been anti-dilutive.

Note 7. Accumulated Other Comprehensive Income

Note 8. Cash, cash equivalents and restricted cash

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


	March 31,		December 31,
	2021			2020

Cash and cash equivalents	$	206,766	$	203,479
Long-term restricted cash		753		753
Total cash, cash equivalents and restricted cash	$	207,519	$	204,232

As of March 31, 2021, we had $0.8 million in restricted cash representing the total of (i) cash collateral for a $0.7 million letter of credit relating to workers’ compensation insurance and (ii) a $0.1 million deposit relating to customs activity.

Note 9. Inventories, net

The components of inventories are as follows:


	March 31,		December 31,
	2021		2020

	(in thousands)
Raw materials	$	100,634	$	100,254
Work in process		34,283		33,867
Finished goods (completed systems)		39,464		26,955
Inventories, net	$	174,381	$	161,076

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 10. 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.

Total warranty liability	$	4,740	$	3,805

Note 11. Fair Value Measurements

Certain assets on our balance sheets are reported at their fair value. Fair value is defined as the 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 12. 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 $48.0 million as of March 31, 2021. The associated lease payments include both an interest component and payment of principal, with the remaining 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 reduces our availability under our credit facility, as described in the next paragraph.

On July 31, 2020, we entered into a Senior Secured Credit Facilities Credit Agreement (the “Credit Agreement”) with Silicon Valley Bank, in its capacity as administrative agent and collateral agent for itself and as a lender, and such other banks and financial institutions or entities that from time to time join as lenders under the Credit Agreement. The Credit Agreement provides for a revolving credit facility in an aggregate principal amount not to exceed $40.0 million. Our obligations under the Credit Agreement are secured by a security interest, senior to any current and future debts and to any security interest, in all of our rights, title, and interest in, to and under substantially all of our assets, subject to limited exceptions, including permitted liens. The revolving credit facility terminates on July 31, 2023. As of March 31, 2021, we were in compliance with all covenant requirements of the Credit Agreement. As of such date, no borrowings had been made under the Credit Agreement, although a letter of credit for $5.9 million, previously issued by Silicon Valley Bank, had been rolled under the Credit Agreement, reducing the funds available for borrowing under the credit line. We entered into a First Amendment to the Credit Agreement with Silicon Valley Bank in March 2021 to (i) align the covenants with our 2021 stock repurchase program, and (ii) establish terms to transition from a Eurodollar based interest rate option to an interest rate benchmark using a secured overnight financing rate (known as “SOFR”) published by the Federal Reserve Bank of New York.

Note 13. Income Taxes

Table of Contents

position. The effective tax rate for the three months ended March 31, 2021 and 2020, respectively, was less than the U.S. statutory rate of 21% due to favorable discrete items related to equity compensation in those periods and Federal research and development tax credits that reduce the annual tax rate.

We had $54.9 million and $57.9 million of net deferred tax assets worldwide relating to net operating loss carryforwards, tax credit carryforwards and other temporary differences, as of March 31, 2021 and December 31, 2020, respectively. These deferred tax assets are available to reduce income taxes in future years. We have a $9.1 million valuation allowance in the U.S. against certain tax credits and state net operating losses due to the uncertainty of their realization based on long-term Company forecasts and the expiration dates on these tax assets. If future operating results of the Company within the U.S. or these foreign jurisdictions are significantly less than our expectations, it is reasonably possible that we would be required to record an additional valuation allowance on our deferred tax assets in the future.

Note 14. Concentration of Risk

For the three months ended March 31, 2021, one customer accounted for 29.6% of total revenue. For the three months ended March 31, 2020, four customers accounted for 20.9%, 16.9%, 14.6% and 10.7% of total revenue, respectively.

At March 31, 2021, one customer accounted for 19.8% of accounts receivable. At December 31, 2020, two customers accounted for 23.8% and 11.9% of accounts receivable, respectively.

Note 15. Share Repurchase

In December 2020, our Board of Directors approved stock repurchases of up to $100 million of our common stock through the end of 2021. During the three months ended March 31, 2021, we purchased 0.3 million shares at an average cost of $38.41 per share. The timing and actual number of shares repurchased under this program 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 22,160 unsettled share repurchases totaling approximately $0.9 million at March 31, 2021. 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 16. 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 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 17. Recent Accounting Guidance

Accounting Standards Update 2019-12 Income Taxes (Topic 740)

We adopted Financial Accounting Standards Board ASU No. 2019-12 “Income Taxes (Topic 740)” as of January 1, 2021 on a prospective basis. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions from the previous standard as well as requiring entities to include franchise tax partially based on income as an income based tax and to account for an enacted change in tax laws or rates in the annual effective tax rate computation in the interim period that includes the enactment date. The guidance in ASU 2019-12 is required for annual reporting periods beginning after December 15, 2020. Adoption of ASU 2019-12 had no material effect on our consolidated financial statements and disclosures.

Overview

We are primarily a producer of ion implantation 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. Our product development and manufacturing activities occur primarily in the United States. Our equipment and service products are highly technical and are sold through a direct sales force in the United States, Europe and Asia. 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 79.8% of total revenue for the three months ended March 31, 2021.

In the first three months of 2021, we delivered strong financial performance driven by demand for our Purion products and gross margins of 42.5% despite the many difficult logistical challenges brought on by trade tensions between the United States and China and the COVID-19 pandemic. We are continuing to work closely with our customers across market segments, even during this difficult time, to provide them with the best ion implant solutions for their specific manufacturing challenges.

In December 2020, the United States Commerce Department placed one of our major Chinese customers, Semiconductor Manufacturing International Corporation (“SMIC”), on the U.S. export controls Entity List. This same customer was identified by the Commerce Department in September 2020 as subject to a military end use rule that required us to obtain export controls licenses from the Commerce Department to ship high energy systems, but not our high current systems, ordered by this customer. As a result of the Entity List classification, we are required to obtain export controls licenses for all U.S. shipments to this customer. We did not receive any export controls licenses for this customer in the quarter ended March 31, 2021. This situation is currently delaying shipments to this customer.

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, 2020 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 ongoing 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, 2020.

Product

Product revenue, which includes systems sales, sales of spare parts, product upgrades and used systems was $126.6 million, or 95.4% of revenue during the three months ended March 31, 2021, compared with $112.1 million, or 94.2% of revenue for the three months ended March 31, 2020. The $14.5 million increase in product revenue for the three

Table of Contents

month period ending March 31, 2021, in comparison to the same period in 2020, was primarily driven by an increase in sales of spare parts, product upgrades and used systems.

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 March 31, 2021 and December 31, 2020 was $22.1 million and $23.1 million, respectively. The net decrease in deferred revenue was primarily due to the recognition of revenue on tool 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 $6.2 million, or 4.6% of revenue for the three months ended March 31, 2021, compared with $6.9 million, or 5.8% of revenue for the three months ended March 31, 2020. 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.

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-ion implant product lines, given that ion implantation systems are the primary driver of our growth and strategic objectives;

●

Systems and Aftermarket revenues, in which “Aftermarket” is

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

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.

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

Three months ended March 31, 2021 Compared with Three months ended March 31, 2020

Ion Implant

Included in total revenue of $132.8 million during the three months ended March 31, 2021 is revenue from sales of ion implant products and services of $128.8 million, or 97.0% of total revenue, compared with $115.0 million, or 96.7%, of total revenue for the three months ended March 31, 2020. The remaining $4.0 million of revenue for the three months ended March 31, 2021 was non-ion implant parts and services.

Table of Contents

Aftermarket

Included in total revenue of $132.8 million during the three months ended March 31, 2021 is revenue from our Aftermarket business of $51.8 million, compared to $36.7 million for the three months ended March 31, 2020. The remaining $81.0 million of revenue for the three months ended March 31, 2021 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 equipment.

Product

Gross margin from product revenue was 44.4% for the three months ended March 31, 2021, compared to 40.1% for the three months ended March 31, 2020. The increase in gross margin resulted from improved margins on Purion systems.

Services

Gross margin from services revenue was 2.6% for the three-month periods ended March 31, 2021, compared to 8.6% for the three months ended March 31, 2020. The decrease in gross margin is attributable to changes in the mix of service contracts.

Our ability to remain competitive depends largely on continuously developing innovative technology, with new and enhanced features and systems and introducing them at competitive prices on a timely basis. Accordingly, based on our strategic plan, we establish annual R&D budgets to fund programs that we expect will solve customers’ high value, high impact, ion implantation challenges.

Three months ended March 31, 2021 Compared with Three months ended March 31, 2020

Research and development expense was $15.7 million during the three months ended March 31, 2021, an increase of $1.1 million, or 7.4%, compared with $14.6 million during the three months ended March 31, 2020. The increase is primarily due to higher supplies and materials costs for ongoing projects, increased depreciation associated with capital additions and an increase in personnel expenses.

Other (expense) income consists primarily of interest expense relating to the finance lease obligation we incurred in connection with the 2015 sale of our headquarters facility 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 $2.1 million for the three months ended March 31, 2021, compared with $1.4 million for the three months ended March 31, 2020. This increase was primarily due to an increase in foreign currency exchange losses of $0.5 million as well as a reduction of $0.4 million in interest income when compared to the three month period ended March 31, 2020.

During the three-month periods ended March 31, 2021 and 2020, we had no significant off-balance-sheet risk such as exchange contracts, option contracts or other hedging arrangements.

Income Tax Provision


	Three months ended							Period-to-period
	March 31,							change
	2021			2020				$		%

Income tax provision	$	1,721			$	1,041		$	680	65.3	%
Percentage of revenue		1.3	%			0.9	%

Income tax expense was $1.7 million for the three months ended March 31, 2021, compared to $1.0 million for the three months ended March 31, 2020. The $0.7 million increase was primarily due to a $6.0 million increase in pretax income partially offset by a tax benefit of $0.2 million due to the expiration of a statute of limitations on an uncertain tax position. The effective tax rate for the three months ended March 31, 2021 and 2020, respectively, was less than the U.S. statutory rate of 21% due to favorable discrete items related to equity compensation in those periods as well as Federal research and development tax credits that reduce the annual tax rate.

Liquidity and Capital Resources

We had $206.8 million in unrestricted cash and cash equivalents at March 31, 2021, in addition to $0.7 million in restricted cash. 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 are considering 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 may also engage in stock repurchases, as discussed below.

During the three months ended March 31, 2021, we generated $15.1 million of cash related to operating activities. During the three months ended March 31, 2020, we generated $39.7 million of cash related to operating activities.

Investing activities for both three months ended March 31, 2021 and 2020 resulted in cash outflows of $1.3 million, respectively, used for capital expenditures.

Financing activities for the three months ended March 31, 2021 resulted in a cash usage of $11.7 million. During the first three months of 2021, $11.6 million in cash was used to repurchase our common stock and $2.4 million was used for payments to government tax authorities for income tax withholding on employee compensation arising from the vesting of RSUs, where shares are withheld by the Company, as well as $0.2 million relating to the reduction of the liability under the finance lease of our corporate headquarters. These amounts were partially offset by $2.5 million of proceeds from the exercise of stock options during the first three months of 2021. In comparison, financing activities for the three months ended March 31, 2020 resulted in cash usage of $4.1 million, $7.5 million of which related to the repurchase of our common stock and $1.2 million related to payments made to government tax authorities for income tax withholding on employee compensation arising from the vesting of RSUs. These amounts were partially offset by $4.5 million of proceeds related to the exercise of stock options and purchase of shares under our prior employee stock purchase plan during the first three months of 2020.

Under the rules of the U.S. Securities and Exchange Commission (the “SEC”), we qualify as a “well-known seasoned issuer,” which allows us to file shelf registration statements to register an unspecified amount of securities that are effective upon filing. On May 29, 2020, we filed such a shelf registration statement with the SEC for the issuance of an unspecified amount of common stock, preferred stock, various series of debt securities and/or warrants to purchase any of such securities, either individually or in units, from time to time at prices and on terms to be determined at the time of any such offering. This registration statement was effective upon filing and will remain in effect for up to three years from filing, prior to which time we may file another shelf registration statement to maintain the availability of this financing option.

On July 31, 2020, we entered into a Senior Secured Credit Facilities Credit Agreement (the “Credit Agreement”) with Silicon Valley Bank. The Credit Agreement provides for a revolving credit facility in an aggregate principal amount not to exceed $40.0 million. Our obligations under the Credit Agreement are secured by a security interest, senior to any current and future debts and to any security interest, in all of our rights, title, and interest in, to and under substantially all of our assets, subject to limited exceptions, including permitted liens. The revolving credit facility terminates on July 31, 2023. As of March 31, 2021, we were in compliance with all covenant requirements of the Credit Agreement. As of such date, no borrowings had been made under the Credit Agreement, although a letter of credit for $5.9 million, previously issued by Silicon Valley Bank, had been rolled under the Credit Agreement, reducing the funds available for borrowing under the credit line. We have no immediate plans to borrow under the Credit Agreement, but we will use the facility for letters of credit, for ongoing working capital needs and to fund general corporate purposes, as desired. We entered into a First Amendment to the Credit Agreement with Silicon Valley Bank in March 2021 to (i) align the covenants with our 2021 stock repurchase program, and (ii) establish terms to transition from a Eurodollar based interest rate option to an interest rate benchmark using a secured overnight financing rate (known as “SOFR”) published by the Federal Reserve Bank of New York.

We believe that based on our current market, revenue, expense and cash flow forecasts, our existing cash, cash equivalents and equity and debt financing capacity will be sufficient to satisfy our anticipated cash requirements for the short and long-term.
