### 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 47.4% of total revenue for the six months ended June 30, 2024.

The first six months of 2024 exhibited continued strong demand for our capital equipment. The overall mature process segment represented 98% of our shipped systems revenue, with 1% of shipments to advanced logic and 1% of shipments to dynamic random-access memory (“DRAM”). Power device shipments comprised 59% of total systems revenue with the general mature segment representing 36%, and image sensors at 4%. Looking ahead, we expect demand from silicon carbide customers within the power segment to remain healthy in the second half, while in general mature, we may see some moderation in revenue in the second half, dependent on the macroeconomic environment and its impact on our customers’ spending patterns. In addition, we expect DRAM customers to start adding capacity as we exit 2024 and into 2025, while “NAND” spending is expected to begin picking up 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.

#### Three months ended June 30, 2024 Compared with Three months ended June 30, 2023

#### Product

Product revenue, which includes systems sales, sales of spare parts, product upgrades and used systems, was $245.4 million, or 95.7% of revenue, during the three months ended June 30, 2024, compared with $265.7 million, or 97.0% of revenue, for the three months ended June 30, 2023. The $20.3 million decrease in product revenue for the three- month period ended June 30, 2024, in comparison to the same period in 2023, was primarily driven by a decrease in system sales.

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 June 30, 2024 and December 31, 2023 was $174.0 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 $11.1 million, or 4.3% of revenue, for the three months ended June 30, 2024, compared with $8.3 million, or 3.0% of revenue, for the three months ended June 30, 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.

#### Six months ended June 30, 2024 Compared with Six months ended June 30, 2023

#### Product

Product revenue was $488.8 million, or 96.1% of revenue, during the six months ended June 30, 2024, compared with $511.7 million, or 96.9% of revenue, for the six months ended June 30, 2023. The $22.9 million decrease in product revenue for the six-month period ended June 30, 2024, in comparison to the same period in 2023, was primarily driven by a decrease in system sales.

#### Services

Services revenue was $20.1 million, or 3.9% of revenue, for the six months ended June 30, 2024, compared with $16.3 million, or 3.1% of revenue, for the six months ended June 30, 2023.

### 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:

A. The portion of Product revenue relating to spare parts, product upgrades and used equipment, 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 process technology and leading edge foundry and logic.

#### Aftermarket and Systems Revenue

#### Three months ended June 30, 2024 Compared with Three months ended June 30, 2023

Included in total revenue of $256.5 million during the three months ended June 30, 2024 is revenue from our Aftermarket business of $57.9 million, compared with $58.8 million of Aftermarket revenue for the three months ended June 30, 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 $198.6 million of revenue for the three months ended June 30, 2024 was systems revenue, compared with $215.2 million of systems revenue for the three months ended June 30, 2023. Systems revenue fluctuates from period to period based on our customers’ capital spending.

#### Six months ended June 30, 2024 Compared with Six months ended June 30, 2023

Included in total revenue of $508.9 million during the six months ended June 30, 2024 is revenue from our Aftermarket business of $114.8 million, compared with $117.6 million of Aftermarket revenue for the six months ended June 30, 2023. The remaining $394.1 million of revenue for the six months ended June 30, 2024 was systems revenue, compared with $410.4 million of systems revenue for the six months ended June 30, 2023.

| Percentage of revenue | ​ | ​ 23.3% | ​ 20.5% | ​ ​ | ​ | ​ ​ | ​ 23.4% | ​ 20.6% | ​ ​ | ​ | ​ ​ | ​ |

Our operating expenses consist primarily of personnel costs, including wages, 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 $35.3 million, or 59.2%, of our total operating expenses for the three months ended June 30, 2024, compared to $33.8 million, or 60.4%, of our total operating expenses for the three months ended June 30, 2023. Personnel costs were $71.7 million, or 60.2%, of our total operating expenses for the six months ended June 30, 2024, compared to $64.5 million, or 59.3%, of our total operating expenses for the six months ended June 30, 2023. The higher personnel costs for the three and six months ended June 30, 2024 are primarily due to increases in wages and headcount as well as stock compensation expense, partially offset by a decrease in bonus expense.

| Percentage of revenue | ​ | 1.8% | 0.4% | ​ ​ | ​ | ​ ​ | ​ | 1.4% | 0.5% | ​ ​ | ​ | ​ ​ | ​ |

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 $4.5 million for the three months ended June 30, 2024, compared with other income of $0.9 million for the three months ended June 30, 2023. The $3.5 million increase in other income (expense) compared to the same prior year period was primarily due to an increase in interest income of $1.7 million and foreign exchange gains of $2.3 million from forward currency exchange contracts partially offset by foreign exchange losses of $2.5 million. Other income was $6.9 million for the six months ended June 30, 2024, compared with other income of $2.5 million for the six months ended June 30, 2023. The $4.5 million increase in other income (expense) compared to the same prior year period was primarily due to an increase in interest income of $3.3 million and foreign exchange gains of $3.8 million from forward currency exchange contracts partially offset by foreign exchange losses of $5.9 million.

### Income Tax Provision

| Income tax provision |  | $6,399 ​ |  | $3,037 | $3,362 |  | 110.7% |  | $13,803 ​ |  | $8,242 | $5,561 |  | 67.5% | ​ |
| Percentage of revenue | ​ | 2.5% | ​ | 1.1% | ​ ​ | ​ | ​ ​ | ​ | 2.7% | ​ | 1.6% | ​ ​ | ​ | ​ ​ | ​ |

Income tax expense was $6.4 million for the three months ended June 30, 2024, compared to $3.0 million for the three months ended June 30, 2023. The $3.4 million increase was primarily due to a decrease in stock compensation deduction. Income tax expense was $13.8 million for the six months ended June 30, 2024, compared to $8.2 million for the six months ended June 30, 2023. The increase was primarily due to a decrease in stock compensation deduction.

The effective tax rate for the three and six months ended June 30, 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 $55.4 million and $53.4 million as of June 30, 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 June 30, 2024, we have recorded a $11.3 million valuation allowance in the U.S. against certain tax credits 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.

### Liquidity and Capital Resources

At June 30, 2024, we had $145.2 million in unrestricted cash and cash equivalents and $403.1 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.

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 six months ended June 30, 2024 and 2023, we generated $82.3 million and $67.3 million, respectively, of cash related to operating activities.

Investing activities for the six months ended June 30, 2024 resulted in cash outflows of $61.3 million, $3.6 million of which was used for capital expenditures and $249.0 million of which was used to purchase short-term investments, offset by $191.3 million related to maturities of short-term investments. Investing activities for the six months ended June 30, 2023 resulted in cash outflows of $73.2 million, $5.2 million of which was used for capital expenditures and $188.9 million of which was used to purchase short-term investments, offset by $120.9 million related to maturities of short-term investments.

Financing activities for the six months ended June 30, 2024 resulted in a cash usage of $40.7 million. During the first six months of 2024, $30.0 million in cash was used to repurchase our common stock and $11.2 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 $0.7 million relating to the reduction of the liability under the finance lease of our corporate headquarters. These amounts were partially offset by $1.2 million of proceeds related to the purchase of shares under our 2020 ESPP during the first six months of 2024. In comparison, financing activities for the six months ended June 30, 2023 resulted in cash usage of $40.1 million, $25.0 million of which related to the repurchase of our common stock and $15.5 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 $0.6 million relating to the reduction of our financing lease liability. These amounts were partially offset by $1.0 million of proceeds related to the purchase of shares under our 2020 ESPP and exercise of stock options during the first six months of 2023.

As of June 30, 2024, we had a security deposit of $5.9 million related to the lease of our corporate headquarters 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.

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.
