Lam Research Corporation 2025 Q3 10-Q 17

EXECUTIVE SUMMARY

Lam Research Corporation is a global supplier of innovative wafer fabrication equipment and services to the semiconductor industry. We have built a strong global presence with core competencies in areas like nanoscale applications enablement, chemistry, plasma and fluidics, advanced systems engineering, and a broad range of operational disciplines. Our products and services are designed to help our customers build smaller and better performing devices that are used in a variety of electronic products, including mobile phones, personal computers, servers, wearables, automotive vehicles, and data storage devices.

Our customer base includes leading semiconductor memory, foundry, and integrated device manufacturers that make products such as non-volatile memory, dynamic random-access memory, and logic devices. Their continued success is part of our commitment to driving semiconductor breakthroughs that define the next generation. Our core technical competency is integrating hardware, process, materials, software, and process control, enabling results on the wafer.

Semiconductor manufacturing, our customers’ business, involves the complete fabrication of multiple dies or integrated circuits on a wafer. This involves the repetition of a set of core processes and can require hundreds of individual steps. Fabricating these devices requires highly sophisticated process technologies to integrate an increasing array of new materials with precise control at the atomic scale. Along with meeting technical requirements, wafer processing equipment must deliver high productivity and be cost-effective.

Demand from cloud computing, artificial intelligence, 5G, the Internet of Things, and other markets is driving the need for increasingly powerful and cost-efficient semiconductors. At the same time, there are growing technical challenges with traditional two-dimensional scaling. These trends are driving significant inflections in semiconductor manufacturing, such as the increasing importance of vertical scaling strategies like three-dimensional architecture as well as multiple patterning to enable shrinks.

We believe we are in a strong position with our leadership and expertise in deposition, etch, and clean markets to facilitate some of the most significant innovations in semiconductor device manufacturing. Our Customer Support Business Group provides products and services to maximize installed equipment performance, predictability, and operational efficiency. Several factors create opportunities for sustainable differentiation for us: (i) our focus on research and development, with several on-going programs relating to sustaining engineering, product and process development, and concept and feasibility; (ii) our ability to effectively leverage cycles of learning from our broad installed base; (iii) our collaborative focus with semi-ecosystem partners, including our close-to-customer focus; (iv) our ability to identify and invest in the breadth of our product portfolio to meet technology inflections; and (v) our focus on delivering our multi-product solutions with a goal to enhance the value of Lam’s solutions to our customers.

In fiscal year 2025, we anticipate strong wafer fabrication equipment spending levels driven by an increase in both the memory and non-memory market segments. In the short term, volatility in the semiconductor industry environment from trade restrictions, tariffs, as well as other direct and indirect risks and uncertainties, have, and in the future may, negatively impact our revenue and operating margin. Over the longer term, we believe that secular demand for semiconductors, combined with technology inflections in our industry, including 3D device scaling, multiple patterning, process flow, and advanced packaging chip integration, will drive sustainable growth and lead to an increase in the served available market for our products and services in the deposition, etch, and clean businesses.

On October 2, 2024, the Company effected a ten-for-one stock split of its common stock and a proportional increase in the number of authorized shares. All references made to share or per share amounts throughout this Form 10-Q, including those presented in the Management’s Discussion and Analysis of Financial Condition and Results of Operations, have been retroactively adjusted to reflect the stock split.

Lam Research Corporation 2025 Q3 10-Q 18

The following table summarizes certain key financial information for the periods indicated below:

In the March 2025 quarter, revenue increased 8% compared to the three months ended December 29, 2024 (the “December 2024 quarter”), driven by an increase in systems revenue as a result of strengthened investments in the Foundry market segment. The deferred revenue balance was $2,010.9 million at the end of the March 2025 quarter, a slight decrease relative to the balance at the end of the December 2024 quarter of $2,031.6 million.

We aim to balance the requirements of our customers with the availability of resources, as well as performance to our operational and financial objectives. As a result, from time to time, we exercise discretion and judgment as to the timing and prioritization of manufacturing and deliveries of products, which has impacted, including in the current fiscal year, and may in the future impact, the timing of revenue recognition with respect to such products.

The increase in gross margin as a percentage of revenue in the March 2025 quarter compared to the December 2024 quarter was primarily a result of favorable changes in customer and product mix. The increase in operating expenses in the March 2025 quarter compared to the December 2024 quarter was driven by an increase in employee-related costs as a result of seasonality and higher headcount, as well as increased supplies expense, offset by lower elective deferred compensation plan-related costs.

Our cash, cash equivalents, and restricted cash balances decreased to $5.5 billion at the end of the March 2025 quarter compared to $5.7 billion at the end of the December 2024 quarter. This decrease was primarily the result of $504.0 million of principal payments on debt instruments and debt issuance costs; $435.3 million of share repurchases, including net share settlement of employee stock-based compensation and excise tax; $295.7 million of dividends paid to stockholders; and $288.1 million of capital expenditures; partially offset by $1,308.7 million of cash generated from operating activities. Employee headcount as of March 30, 2025 was approximately 18,600.

RESULTS OF OPERATIONS

Revenue

The increase in revenue for the nine months ended March 30, 2025 compared to the same period in 2024 was due to increases in equipment spending by our customers across all market segments as well as higher customer support-related revenue.

Lam Research Corporation 2025 Q3 10-Q 19

The following table presents our revenue disaggregated between systems and customer support-related revenue:

Please refer to Note 3, “Revenue,” to the Condensed Consolidated Financial Statements of this Form 10-Q for additional information regarding the composition of the two categories into which revenue has been disaggregated.

The percentage of leading- and non-leading-edge equipment and upgrade revenue from each of the markets we serve was as follows:

The decrease in the memory market segment for the March 2025 quarter compared to the December 2024 quarter was primarily attributable to a decrease in non-volatile memory. There was also a decrease in Logic spending by our customers in the quarter. These decreases were offset by increased Foundry spending for both leading and mature node investments.

Gross Margin

Gross margin as a percentage of revenue was higher in the March 2025 quarter compared to the December 2024 quarter mainly as a result of favorable customer and product mix.

The increase in gross margin as a percentage of revenue in the nine months ended March 30, 2025 compared to the same period in the prior year was primarily due to improved factory efficiencies, partially offset by unfavorable changes in customer mix and increased transformational charges.

Research and Development

We continued to make significant R&D investments in the March 2025 quarter focused on leading-edge deposition, etch, clean and other semiconductor manufacturing processes. The increase in R&D expense in the March 2025 quarter compared to the December 2024 quarter was primarily driven by an increase in employee-related costs as a result of seasonality and higher headcount, as well as increased lab-related spending, partially offset by lower elective deferred compensation plan-related costs.

R&D expense in the nine months ended March 30, 2025 increased compared to the same period in the prior year, driven by higher employee-related costs as a result of increased headcount, as well as spending on outside services, partially offset by lower supplies expense and lower elective deferred compensation plan-related costs.

Lam Research Corporation 2025 Q3 10-Q 20

Selling, General, and Administrative

SG&A expense during the March 2025 quarter decreased compared to the December 2024 quarter as a result of lower facilities costs and elective deferred compensation plan-related costs.

SG&A expense during the nine months ended March 30, 2025 increased compared to the same period in the prior year, driven by higher employee-related costs as a result of increased headcount as well as higher spending for transformational activities, partially offset by lower elective deferred compensation plan-related costs.

Restructuring Charges, N****et

In fiscal year 2023, we initiated a restructuring plan that continued into fiscal year 2024, designed to better align our cost structure with our outlook for the economic environment and business opportunities. Under the plan we terminated approximately 1,760 employees, incurring expenses related to employee severance and separation costs. Employee severance and separation costs were primarily related to severance, non-cash severance, including equity award compensation expense, pension and other termination benefits. Additionally, we made a strategic decision to relocate certain manufacturing activities to pre-existing facilities. The restructuring plan was substantially completed as of June 30, 2024.

No restructuring charges were recorded during the nine months ended March 30, 2025. During the nine months ended March 31, 2024, the company recorded net restructuring costs of $57.1 million.

Please refer to Note 14, “Restructuring charges, net,” to our Condensed Consolidated Financial Statements, included in Part I of this Form 10-Q for additional information.

Other Income (Expense), Net

Other income (expense), net consisted of the following:

Interest income decreased in the March 2025 quarter as compared to the December 2024 quarter, primarily due to lower interest rates and lower cash average balances. Interest income decreased for the nine months ended March 30, 2025, compared to the same period in 2024, primarily due to lower interest rates, partially offset by higher cash balances.

Interest expense was at consistent levels for all periods presented.

The variations in deferred compensation plan-related assets, net were driven by fluctuations in the fair market value of the underlying funds for all periods presented.

Foreign exchange fluctuations were primarily due to currency movements against portions of our unhedged balance sheet exposures for all periods presented.

The variation in other, net was primarily driven by fluctuations in the fair market value of equity investments for all periods presented.

Lam Research Corporation 2025 Q3 10-Q 21

Income Tax Expense

Our provision for income taxes and effective tax rate for the periods indicated were as follows:

The increase in the effective tax rate for the March 2025 quarter compared to the December 2024 quarter was primarily due to the recognition of previously unrecognized tax benefits from lapses of statutes of limitation and the income tax benefit from a change in tax law in the December 2024 quarter.

The increase in the effective tax rate for the nine months ended March 30, 2025 compared to the same period in the prior year was primarily due to lower benefit of the R&D tax credit as a percentage of pre-tax income and lower stock-based compensation excess tax benefits, offset by the income tax benefit from a change in tax law in the nine months ended March 30, 2025.

International revenues account for a significant portion of our total revenues, such that a material portion of our pre-tax income is earned and taxed outside the United States. International pre-tax income is taxable in the United States at a lower effective tax rate than the federal statutory tax rate. Please refer to Note 7, “Income Taxes,” to our Consolidated Financial Statements in Part II, Item 8 of our 2024 Form 10-K for additional information.

We re-evaluate uncertain tax positions on a quarterly basis. This evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit, and new audit activity. Any change in recognition or measurement would result in the recognition of a tax benefit or an additional charge to the tax provision.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our critical accounting policies and estimates are unchanged from those disclosed in “Critical Accounting Policies and Estimates” in Part II, Item 7 of our 2024 Form 10-K.

Recent Accounting Pronouncements

See Note 2 - Recent Accounting Pronouncements, of our Condensed Consolidated Financial Statements, included in Part 1 of this Form 10-Q.

LIQUIDITY AND CAPITAL RESOURCES

Total gross cash, cash equivalents, and restricted cash balances were $5.5 billion at March 30, 2025 compared to $5.9 billion as of June 30, 2024. The decrease was primarily driven by $2,130.0 million of share repurchases, including net share settlement on employee stock-based compensation and excise tax; $854.3 million in dividends paid; $587.0 million in capital expenditures; and $506.0 million of principal payments on debt instruments and debt issuance costs, partially offset by cash generated from operating activities totaling $3,619.1 million.

Cash Flow from Operating Activities

Net cash provided by operating activities of $3,619.1 million during the nine months ended March 30, 2025 consisted of (in thousands):

Changes in operating asset and liability accounts, net of foreign exchange impact, included the following uses of cash: increases in accounts receivable of $706.3 million, inventory of $319.7 million, and prepaid expenses and other current assets of $41.9 million.

Lam Research Corporation 2025 Q3 10-Q 22

These uses of cash were offset by the following sources of cash: increases in deferred gross profit of $464.6 million, trade accounts payable of $193.8 million, and accrued expenses and other liabilities of $72.5 million.

Cash Flow from Investing Activities

Net cash used for investing activities during the nine months ended March 30, 2025 was $578.8 million, primarily consisting of capital expenditures.

Cash Flow from Financing Activities

Net cash used for financing activities during the nine months ended March 30, 2025 was $3,427.1 million, primarily consisting of $2,130.0 million in treasury stock repurchases, including net share settlement on employee stock-based compensation and excise tax, $854.3 million in dividends paid; and $506.0 million of principal payments on debt instruments and debt issuance costs.

Liquidity

Given that the semiconductor industry is highly competitive and has historically experienced rapid changes in demand, we believe that maintaining sufficient liquidity reserves is important to support sustaining levels of investment in R&D and capital infrastructure. Anticipated cash flows from operations based on our current business outlook, combined with our current levels of cash and cash equivalents as of March 30, 2025, are expected to be sufficient to support our anticipated levels of operations, investments, debt service requirements, capital expenditures, capital redistributions, and dividends through at least the next twelve months. However, factors outside of our control, including uncertainty in the global economy and the semiconductor industry, as well as disruptions in credit markets, have in the past, are currently, and could in the future, impact customer demand for our products, as well as our ability to manage normal commercial relationships with our customers, suppliers, and creditors.

During the three months ended March 30, 2025, $500 million principal value of our 2025 Notes were settled upon maturity using available cash on hand.

In January 2025, we entered into a Third Amended and Restated Credit Agreement. The amendment increased the unsecured revolving credit facility commitment from $1.5 billion to $2.0 billion and extended the maturity of the facility from June 2026 to January 2030. The facility provides for an expansion option that will allow us, subject to certain requirements, to request an increase in the facility of up to an additional $750 million, for a potential total commitment of $2.75 billion. Please refer to Note 11, “Long-term Debt and Other Borrowings,” to our Condensed Consolidated Financial Statements, included in Part I of this form 10-Q for additional information.

In the longer term, liquidity will depend to a great extent on our future revenues and our ability to appropriately manage our costs based on demand for our products and services. While we have substantial cash balances, we may require additional funding and need or choose to raise the required funds through borrowings or public or private sales of debt or equity securities. We believe that, if necessary, we will be able to access the capital markets on terms and in amounts adequate to meet our objectives. However, domestic and global macroeconomic and political conditions could cause disruptions to the capital markets and otherwise make any financing more challenging, and there can be no assurance that we will be able to obtain such financing on commercially reasonable terms or at all.

For financial market risks related to changes in interest rates and foreign currency exchange rates, refer to Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk”, in our 2024 Form 10-K. Our exposure related to market risk has not changed materially since June 30, 2024.

Design of Disclosure Controls and Procedures and Internal Control over Financial Reporting

We maintain disclosure controls and procedures and internal control over financial reporting that are designed to comply with Rule 13a-15 of the Exchange Act. In designing and evaluating the controls and procedures associated with each, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and that the effectiveness of controls cannot be absolute because the cost to design and implement a control to identify errors or mitigate the risk of errors occurring should not outweigh the potential loss caused by the errors that would likely be detected by the control. Moreover, we believe that a control system cannot be guaranteed to be 100% effective all of the time. Accordingly, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met.

Disclosure Controls and Procedures

As required by Exchange Act Rule 13a-15(b), as of March 30, 2025, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rule 13a-15(e). Based upon that evaluation, our Chief

Lam Research Corporation 2025 Q3 10-Q 23

Executive Officer, along with our Chief Financial Officer, concluded that our disclosure controls and procedures are effective at the reasonable assurance level.

We intend to review and evaluate the design and effectiveness of our disclosure controls and procedures on an ongoing basis and to correct any material deficiencies that we may discover. Our goal is to ensure that our senior management has timely access to material information that could affect our business.

Changes in Internal Control over Financial Reporting

There has been no change in our internal control over financial reporting during our most recent fiscal quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Effectiveness of Controls

While we believe the present design of our disclosure controls and procedures and internal control over financial reporting is effective at the reasonable assurance level, future events affecting our business may cause us to modify our disclosure controls and procedures or internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. Legal Proceedings

Please refer to the subsection entitled “Legal Proceedings” within Note 12 “Commitments and Contingencies," to our Condensed Consolidated Financial Statements in this quarterly report on Form 10-Q.

In addition to the other information in this Form 10-Q, the following risk factors should be carefully considered in evaluating us and our business because such factors may significantly impact our business, operating results, and financial condition. As a result of these risk factors, as well as other risks discussed in our other SEC filings, our actual results could differ materially from those projected in any forward-looking statements. No priority or significance is intended by, nor should be attached to, the order in which the risk factors appear.

INDUSTRY AND CUSTOMER RISKS

We Depend on Creating New Products and Processes and Enhancing Existing Products and Processes for Our Success; Consequently, We Are Subject to Risks Associated with Rapid Technological Change

Rapid technological changes in semiconductor manufacturing processes subject us to increased pressure to develop technological advances that enable those processes. We believe that our future success depends in part upon our ability to develop and offer new products with improved capabilities and to continue to enhance our existing products. If new products or existing products have reliability, quality, design, or safety problems, our performance may be impacted by reduced orders, higher manufacturing costs, delays in acceptance of and payment for new products, and additional service and warranty expenses. We may be unable to develop and manufacture products successfully, or products that we introduce may fail in the marketplace. For more than 25 years, the primary driver of technology advancement in the semiconductor industry has been to shrink the lithography that prints the circuit design on semiconductor chips. That driver could be approaching its technological limit, leading semiconductor manufacturers to investigate more complex changes in multiple technologies in an effort to continue technology development. In addition, the emergence of “big data” and new tools such as machine learning and artificial intelligence (“AI”) that capitalize on the availability of large data sets is leading semiconductor manufacturers and equipment manufacturers to pursue new products and approaches that exploit those tools to advance technology development. In the face of uncertainty on which technology solutions will become successful, we will need to focus our efforts on developing the technology changes that are ultimately successful in supporting our customers’ requirements. Our failure to develop and offer the correct technology solutions in a timely manner with productive and cost-effective products could adversely affect our business in a material way. Our failure to commercialize new products in a timely manner could result in loss of market share, unanticipated costs, and inventory obsolescence, which would adversely affect our financial results.

In order to develop new products and processes and enhance existing products and processes, we expect to continue to make significant investments in R&D, to investigate the acquisition of products and technologies, to invest in or acquire businesses or technologies, and to pursue joint development relationships with customers, suppliers, or other members of the industry. Our investments and acquisitions may not be as successful as we may expect, particularly in the event that we invest in or acquire product lines and technologies that are new to us. We may find that acquisitions are not available to us, for regulatory or other reasons, and that we must therefore limit ourselves to collaboration and joint venture development activities that do not have the same benefits as acquisitions. Pursuing development through collaboration and/or joint development activities rather than through an acquisition may pose substantial challenges for management, including those related to aligning business objectives; sharing confidential information, intellectual property and data; sharing value with third parties; and realizing synergies that might have been available in an acquisition but are not available through a joint development project. We must manage product transitions and joint development relationships successfully, as the introduction of new products could adversely affect our sales of existing products and certain jointly developed technologies may be subject to restrictions on our ability to share that technology, which could limit our market for products incorporating those technologies. Future technologies, processes, or product developments may render our current product offerings obsolete, leaving us with non-competitive products, obsolete inventory, or both. Moreover, customers may adopt new technologies or processes to address the complex challenges associated with next-generation devices. This shift may result in a reduction in the size of our addressable markets or could increase the relative size of markets in which we either do not compete or have relatively low market share.

We Face a Challenging and Complex Competitive Environment

We face significant competition from multiple competitors, and our competitors may be able to develop products comparable or superior to those we offer or may adapt more quickly to new technologies or evolving customer requirements. In particular, while we continue to develop product enhancements that we believe will address future customer requirements, we may fail in a timely manner to identify those future customer requirements, to devote appropriate resources to developing products to address those requirements, or to complete the development or introduction of these additional product enhancements successfully, or these product enhancements may not achieve market acceptance or be competitive. Accordingly, competition may intensify, and we may be

Lam Research Corporation 2025 Q3 10-Q 25

unable to continue to compete successfully in our markets, which could have a material adverse effect on our revenues, operating results, financial condition, and/or cash flows.

With increased consolidation efforts in our industry, as well as the emergence and strengthening of new, regional competitors, we may face increasing competitive pressures. Other companies continue to develop systems and/or acquire businesses and products that are competitive to ours and may introduce new products and product capabilities that may affect our ability to sell and support our existing products. We face a greater risk if our competitors enter into strategic relationships with leading semiconductor manufacturers covering products similar to those we sell or may develop, as this could adversely affect our ability to sell products to those manufacturers.

We believe that to remain competitive we must devote significant financial resources to offer products that meet our customers’ needs, to maintain customer service and support centers worldwide, and to invest in product and process R&D. Technological changes and developing technologies have required, and are expected to continue to require, new and costly investments. Certain of our competitors, including those that are created and financially backed by foreign governments, have substantially greater financial resources and more extensive engineering, manufacturing, marketing, and customer service and support resources than we do and therefore have the potential to offer customers a more comprehensive array of products and/or product capabilities and to therefore achieve additional relative success in the semiconductor equipment industry. These competitors may deeply discount or give away products similar to those that we sell, challenging or even exceeding our ability to make similar accommodations and threatening our ability to sell those products. We also face competition from our own customers, who in some instances have established affiliated entities that manufacture equipment similar to ours. In addition, we face competition from companies that exist in a mor
