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, 2023 has been derived from the audited consolidated financial statements at that date but does not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. As of March 31, 2024, there have been no material changes in the Company’s significant accounting policies, other than with respect to the Company’s accounting policy for derivative financial instruments, which it had not held in prior periods, as described in Note 2 below. For further information, refer to the consolidated financial statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (the “SEC”) on February 23, 2024, as amended by Amendment No. 1 thereto, filed with the SEC on February 28, 2024 (as so amended, the “2023 Form 10-K”).

Note 2. Significant Accounting Policies

Derivative instruments

We are exposed to certain risks relating to our ongoing business operations, including market risks relating to fluctuations in foreign currency exchange rates. We have entered into forward exchange contracts in order to mitigate risks associated with fluctuations in exchange rates on forecasted transactions denominated in foreign currencies and to minimize the impact of foreign currency fluctuations on our earnings and cash flows. These contracts have month-to-month settlement dates. As of March 31, 2024, we had open contracts with a notional value of $100 million. We measure these instruments at fair value and recognize assets or liabilities associated with the intrinsic value on these open contracts on the Consolidated Balance Sheets at the end of each reporting period. At March 31, 2024, the recognized unrealized gain on these forward exchange contracts was approximately $18 thousand and is included in other current assets within our Consolidated Balance Sheets. Unrealized gains and losses are shown in our cash flows from operating activities within our Consolidated Statement of Cash Flows. We have not designated these forward exchange contracts as hedging instruments and we record changes in the fair values at each measurement date in Other, net on the Consolidated Statements of Operations. For the three months ended March 31, 2024, we recorded $1.5 million of gain on forward currency exchange contracts.

We do not offset fair value amounts of derivative instruments. We do not use derivative instruments for speculative purposes.

Note 3. 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.

Table of Contents

The 2012 Equity Plan is more fully described in Note 13 to the consolidated financial statements in our 2023 Form 10-K.

We recognized stock-based compensation expense of $4.7 million and $3.2 million for the three-month periods ended March 31, 2024 and 2023, respectively. These amounts include compensation expense related to RSUs and non-qualified stock options.

In the three-month period ended March 31, 2024, we issued 41,941 shares of common stock upon vesting of RSUs. In the three-month period ended March 31, 2023, we issued 57,604 shares of common stock upon vesting of RSUs and stock option exercises. In the three-month period ended March 31, 2024, we received no proceeds in connection with the exercise of stock options. In the three-month period ended March 31, 2023, we received proceeds of $25.0 thousand in connection with the exercise of stock options.

Note 4. Leases

We have operating leases for manufacturing, 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 Beverly, Massachusetts. We review all agreements to determine if the agreement contains a lease component. An agreement contains a lease component if it provides for the use of a specific physical space or a specific physical item.

We recognize operating lease obligations under Accounting Standards Codification Topic 842, Leases (“Topic 842”). The guidance in Topic 842 requires recognition of lease assets and related liabilities 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 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 sheets; (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 by one to three years. The exercise of lease renewal options is at our sole discretion. For lease extensions that are reasonably certain to occur, we have included the 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:

The lease of our corporate headquarters, shown below under finance leases, had an original lease term of 22 years, beginning in January 2015 and expiring in January 2037, with renewal options. All other locations are treated as operating leases, with lease terms ranging from one to 16 years. The tables below reflect the minimum cash outflow regarding our current lease obligations as well as the weighted-average remaining lease term and weighted-average discount rates used in our calculation of our lease obligations and right-of-use assets as of March 31, 2024:

The majority of our system transactions have either (1) payment terms of 90% due upon shipment of the system and 10% due upon acceptance or (2) a pre-shipment deposit ranging from 20% to 60%, with the remainder due upon shipment, less 10% due at acceptance. Aftermarket transaction payment terms typically provide that payment is due either within 30 or 60 days after the service is provided or parts delivered.

Note 6. 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.

We maintain an allowance for credit losses, which represents an estimate of expected losses over the remaining contractual life of our receivables, considering current market conditions and estimates for supportable forecasts when appropriate. The estimate is a result of our ongoing assessments and evaluations of collectability, historical loss experience, and future expectations in estimating credit losses in our receivable portfolio. We use historical loss experience rates and apply 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

Table of Contents

experience, loss migration, delinquency trends, collection experience, current economic conditions, trade restrictions, estimates for supportable forecasts, when appropriate, and credit risk characteristics.

We evaluate the credit risk of the customer when extending credit based on a combination of financial and qualitative factors that may affect our 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 our 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. We recorded $0.5 million of recovery of bad debt expense for the three-month period ended March 31, 2024. We did not have any allowance or incur any credit losses or recoveries for the three-month period ended March 31, 2023. As of both March 31, 2024 and 2023, we had no provision for credit losses.

Note 7. 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 shares of common stock 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 shares of common stock that would have been outstanding if the potentially dilutive shares of common stock 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,
	2024		2023

Net income available to common stockholders	$	51,595	$	47,697
Weighted average shares of common stock outstanding used in computing basic income per share		32,638		32,744
Incremental options and RSUs		288		549
Weighted average shares of common stock used in computing diluted net income per share		32,926		33,293
Net income per share
Basic	$	1.58	$	1.46
Diluted	$	1.57	$	1.43

Diluted weighted average shares of common stock outstanding does not include 19,548 and 1,120 common equivalent shares issuable with respect to outstanding equity awards for the three-month periods ended March 31, 2024 and 2023, respectively, as their effect would have been anti-dilutive.

As of March 31, 2024, we had $6.7 million in restricted cash representing the total of (i) a $5.9 million cash collateral relating to our lease for our headquarters in Beverly, Massachusetts, (ii) a $0.7 million letter of credit relating to workers’ compensation insurance and (iii) a $0.1 million deposit relating to customs activity. See Note 13 for further discussion on the $5.9 million cash collateral.

Note 10. Inventories, net

The components of inventories are as follows:

Finished goods (completed systems)		28,235		29,909
Inventories, net	$	312,170	$	306,482

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 our 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 11. 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, if applicable, defer the portion of systems revenue attributable to 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 12. Fair Value Measurements

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 with initial maturities of three months or less are included in cash and cash equivalents in the consolidated balance sheets. Other investments that have a maturity of greater than three months but less than one year are included within short-term investments in the consolidated balance sheets.

(c) Other Financial Instruments

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

(d) Forward Currency Exchange Contracts

Beginning in February 2024, we entered into forward currency exchange contracts to minimize the impact of foreign currency fluctuations on our earnings and cash flows. These contracts have month-to-month settlement dates. Any gains or losses on these contracts are reported within Other, net within our Consolidated Statement of Operations. Any open contracts at period end that have settlement dates within one month after the reported period end and any mark-to-market valuation adjustments related to these open contracts are recorded within the current asset or current liability account and any unrealized gain or loss recognized is recorded within Other, net within our Consolidated Statement of Operations. These contracts are measured at fair value using observable market inputs such as forward currency exchange rates and our counterparties’ credit risks. Based on these inputs, the derivative instruments are classified within Level 2 of the valuation hierarchy. At March 31, 2024, the recognized unrealized gain on these forward exchange contracts was approximately $18 thousand and is included in other current assets within our Consolidated Balance Sheets. Based on our continued ability to trade and enter into forward contracts, we consider the markets for our fair value instruments to be active. We evaluated the credit risk associated with the counterparties to these derivative instruments and determined that as of March 31, 2024, such credit risks have not had an adverse impact on the fair value of these instruments.

Note 13. 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 $44.8 million as of March 31, 2024. 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.

Table of Contents

As of March 31, 2024, we had a security deposit of $5.9 million related to this lease in the form of a cash collateralized letter of credit issued with UBS Bank USA, which is classified as long-term restricted cash on our balance sheet at March 31, 2024.

Note 14. Income Taxes

Income tax expense was $7.4 million for the three months ended March 31, 2024, compared to $5.2 million for the three months ended March 31, 2023. The $2.2 million increase was primarily due to an increase in pre-tax income and a decrease in stock compensation deduction partially offset by the tax deduction related to foreign sales taxed at a lower rate.

The effective tax rate for the three months ended March 31, 2024 was less than the U.S. statutory rate of 21% due to a forecasted Foreign Derived Intangible Income deduction, Federal research and development tax credits and a favorable discrete item related to equity compensation that reduces the annual tax rate.

The deferred income taxes of $54.5 million and $53.4 million as of March 31, 2024 and December 31, 2023, respectively, reflect the net tax effect of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, as well as the tax effect of carryforwards. As of March 31, 2024, we have recorded a $10.8 million valuation allowance in the U.S. against certain tax credits and state net operating losses due to the uncertainty of their realization. Realization of our net deferred tax assets is dependent on future taxable income. We believe it is more likely than not that such assets will be realized; however, ultimate realization could be impacted by market conditions and other variables not known or anticipated at this time.

Note 15. Concentration of Risk

For the three months ended March 31, 2024, no individual customer accounted for greater than ten percent of total revenue. For the three months ended March 31, 2023, two customers accounted for 15.2% and 12.9% of total revenue, respectively.

At March 31, 2024, no individual customer accounted for greater than ten percent of accounts receivable. At December 31, 2023, one customer accounted for 12.2% of accounts receivable.

Note 16. Share Repurchase

In February 2022, our Board of Directors approved stock repurchases of up to $100 million of our common stock. In August 2023, our Board of Directors approved additional funding of $200 million for our stock repurchase program, to be available on full utilization of the $100 million repurchase funding approved in February 2022. During the three months ended March 31, 2024, we repurchased 0.1 million shares at an average cost of $122.99 per share. The timing and actual number of any additional shares to be repurchased under this program will depend on various factors including price, corporate and regulatory requirements, alternative investment opportunities and other market conditions.

Repurchased shares are accounted for when the transaction is settled and returned to the status of authorized but unissued shares. Accordingly, on our balance sheet, the repurchase price is deducted from common stock 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 17. 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 18. Recent Accounting Guidance

In November 2023 the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”). ASU 2023-07 is intended to enhance disclosures for significant segment expenses for all public entities required to report segment information in accordance with ASC Topic 280, Segment Reporting (“ASC 280”). ASC 280 requires a public entity to report for each reportable segment a measure of segment profit or loss that its chief operating decision maker (“CODM”) uses to assess segment performance and to make decisions about resource allocations. ASU 2023-07 is intended to improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more useful financial analyses. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply ASU 2023-07 retrospectively to all prior periods presented in the consolidated financial statements. We are currently evaluating the impact of ASU 2023- on our future consolidated financial statements and related disclosures.

In December 2023 the FASB issued Accounting Standards Update 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). ASU 2023-09 is intended to enhance the transparency and decision usefulness of income tax disclosures. ASU 2023-09 addresses investor requests for enhanced income tax information primarily through changes to the rate reconciliation and income taxes paid information. Early adoption is permitted. A public entity should apply ASU 2023-09 prospectively to all annual periods beginning after December 15, 2024. We are currently evaluating the impact of ASU 2023-09 on our future consolidated financial statements and related disclosures.

The forward-looking statements contained herein are based on current expectations and entail various risks and uncertainties that could cause actual results to differ materially from those expressed in such forward-looking statements. Factors that might cause such a difference include, among other things, those set forth under "Liquidity and Capital Resources" below and under “Risk Factors” in Part I, Item 1A to our 2023 Form 10-K, which discussion is incorporated herein by reference. Readers are cautioned not to place undue reliance on these forward-looking statements, which reflect management's analysis only as of the date hereof. We assume no obligation to update these forward-looking statements to reflect actual results or changes in factors or assumptions affecting forward-looking statements, except as may be required by law.

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 currently occur primarily in the United States and South Korea. 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 54.8% of total revenue for the three months ended March 31, 2024.

The first three months of 2024 exhibited continued strong demand for our capital equipment. The overall mature process segment represented 99% of our shipped systems revenue, with 1% of shipments to dynamic random-access memory (“DRAM”). Power device shipments comprised 55% of total systems revenue with the general mature segment representing 41%, and image sensors at 3%. Looking ahead, we expect that the general mature process technology markets may improve in the second half of 2024, and DRAM and “Not AND” memory segments are forecast to have a strong year in 2025.

Critical Accounting Estimates

Management’s discussion and analysis of our financial condition and results of operations included herein and in our 2023 Form 10-K 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 Condition and Results of Operations” included in our 2023 Form 10-K.

Product

Product revenue, which includes systems sales, sales of spare parts, product upgrades and used systems, was $243.4 million, or 96.5% of revenue, during the three months ended March 31, 2024, compared with $246.0 million, or 96.8% of revenue, for the three months ended March 31, 2023. The $2.6 million decrease in product revenue for the three-month period ended March 31, 2024, in comparison to the same period in 2023, was primarily driven by a decrease in aftermarket sales.

Table of Contents

Deferred revenue includes payments received in advance of system sales as well as deferral of revenue from systems sales for installation and other future performance obligations. The total amount of deferred revenue at March 31, 2024 and December 31, 2023 was $208.4 million and $210.9 million, respectively.

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 $9.0 million, or 3.5% of revenue, for the three months ended March 31, 2024, compared with $8.0 million, or 3.2% of revenue, for the three months ended March 31, 2023. 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:

●

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 process technology and leading edge foundry and logic.

Aftermarket and Systems Revenue

Included in total revenue of $252.4 million during the three months ended March 31, 2024 is revenue from our Aftermarket business of $56.9 million, compared with $58.8 million of Aftermarket revenue for the three months ended March 31, 2023. 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. The remaining $195.5 million of revenue for the three months ended March 31, 2024 was from system sales, compared with $195.2 million of systems revenue for the three months ended March 31, 2023. Systems revenue fluctuates from period to period based on our customers’ capital spending.

Total gross profit	$	116,051		$	104,019		$	12,032	11.6	%
Gross margin		46.0	%		41.0	%

Product

Gross margin from product revenue was 47.5% for the three months ended March 31, 2024, compared to 42.0% for the three months ended March 31, 2023. The increase in gross margin primarily resulted from a favorable mix of system revenue.

Services

Gross margin from services revenue was 6.1% for the three months ended March 31, 2024, compared to 9.8% for the three months ended March 31, 2023. The decrease in gross margin is attributable to changes in the mix of service contracts.

Operating Expenses

The following table sets forth our operating expenses:

Total operating expenses	$	59,512		$	52,662		$	6,850	13.0	%
Percentage of revenue		23.6	%		20.8	%

Our operating expenses consist primarily of personnel costs, including salaries, commissions, incentive-based compensation, 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 are our largest expense, representing $36.4 million, or 61.2%, of our total operating expenses for the three months ended March 31, 2024, compared to $30.7 million, or 58.2%, of our total operating expenses for the three months ended March 31, 2023. The higher personnel costs for the three months ended March 31, 2024 are primarily due to increases in salary associated with an increase in headcount as well as bonus and stock compensation expenses.

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 research and development budgets to fund programs that we expect will solve customers’ high value, high impact, ion implantation challenges.

Other income (expense):	$	2,460		$	1,545		$	915	59.2	%

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

Other income was $2.5 million for the three months ended March 31, 2024, compared with other income of $1.5 million for the three months ended March 31, 2023. The $0.9 million change in other income (expense) compared to the same prior year period was primarily due to an increase in interest income of $1.6 million and an increase in foreign exchange losses of $2.2 million partially offset by foreign exchange gains of $1.5 million from forward currency exchange contracts.

Liquidity and Capital Resources

At March 31, 2024, we had $134.0 million in unrestricted cash and cash equivalents and $396.2 million in short-term investments, in addition to $6.7 million in restricted cash. Management believes that maintaining a strong cash balance is necessary to fund a continuing ramp in our business which can require significant cash investment to meet sudden demand. Additionally, we are using cash to repurchase shares as part of our stock repurchase program and are considering both organic and inorganic opportunities to drive future growth, for which cash resources will be necessary.

Table of Contents

Our liquidity is affected by many factors. Some of these relate specifically to the operations of our business, for example, the rate of sales 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 industry requires ongoing investments in operations and research and development that are not easily adjusted to reflect changes in revenue. As a result, profitability and cash flows can fluctuate more widely than revenue. Stock repurchases, as discussed below, also reduce our cash balances.

During the three months ended March 31, 2024 and 2023, we generated $42.2 million and $34.6 million, respectively, of cash related to operating activities.

Investing activities for the three months ended March 31, 2024 resulted in cash outflows of $55.7 million, $1.6 million of which was used for capital expenditures and $145.1 million of which was used to purchase short-term investments, offset by $91.1 million related to maturities of short-term investments. Investing activities for the three months ended March 31, 2023 resulted in cash outflows of $33.0 million, $2.2 million of which was used for capital expenditures and $61.8 million of which was used to purchase short-term investments, offset by $31.0 million related to maturities of short-term investments.

Financing activities for the three months ended March 31, 2024 resulted in a cash usage of $18.1 million. During the first three months of 2024, $15.0 million in cash was used to repurchase our common stock and $2.7 million was used for payments to government tax authorities for income tax withholding on employee compensation arising from the vesting of RSUs, where units are withheld by us to cover taxes, as well as $0.4 million relating to the reduction of the liability under the finance lease of our corporate headquarters. In comparison, financing activities for the three months ended March 31, 2023 resulted in cash usage of $16.7 million, $12.5 million of which related to the repurchase of our common stock and $3.9 million of which related to payments made to government tax authorities for income tax withholding on employee compensation arising from the vesting of RSUs, as well as $0.3 million relating to the reduction of our financing lease liability.

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.

Commitments and Contingencies

Significant commitments and contingencies at March 31, 2024 are consistent with those discussed in Item 7, “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” and Note 16 to the consolidated financial statements included in our 2023 Form 10-K.
