Lam Research Corporation 2024 Q1 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, 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 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 opportunity 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; (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.

Overall calendar year 2023 customer demand weakened due to wafer fabrication equipment spending reductions resulting primarily from weakness in the memory market. In addition, the U.S. government’s restrictions on sales of equipment, parts and service for specific technologies and customers in China further impacted equipment demand in the year. As a result of the reduced business levels in calendar year 2023, we initiated a restructuring plan in the quarter ended March 26, 2023 designed to better align the Company’s cost structure with our outlook. We incurred a charge for the workforce actions associated with the restructuring plan of approximately $107.1 million in the second half of fiscal year 2023 and $5.5 million in the September 2023 quarter. We continue to work towards a number of business process improvements and initiatives and expect to incur expenditures in the range of $250 million, inclusive of the restructuring activity. Risks and uncertainties related to trade restrictions and the semiconductor demand environment may continue to 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.

Lam Research Corporation 2024 Q1 10-Q 18

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

In the September 2023 quarter, revenue increased 9% compared to the June 2023 quarter, primarily as a result of increased investments in the DRAM segment as well as increased spending by our China customers for mature node equipment. The deferred revenue balance was $1,690.4 million at the end of the September 2023 quarter, a decrease to the balance at the end of the June 2023 quarter of $1,837.9 million, primarily due to a decrease in advanced deposits. 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 delivery of products, which has impacted, 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 September 2023 quarter compared to the June 2023 quarter was primarily due to favorable customer mix, partially offset by unfavorable factory absorption costs. The increase in operating expenses in the September 2023 quarter compared to the June 2023 quarter was primarily driven by increases in employee-related costs, supplies expense, and outside service spending, partially offset by a decrease in deferred compensation plan-related costs.

Our cash and cash equivalents, investments, and restricted cash and investments balances decreased to $5.2 billion at the end of the September 2023 quarter compared to $5.6 billion at the end of the June 2023 quarter. This decrease was primarily the result of $843.2 million of share repurchases, including net share settlement of employee stock-based compensation; $253.1 million of repayment of debt, largely associated with the purchase of certain properties under finance leases; and $230.3 million of dividends paid to stockholders, partially offset by $951.2 million of cash generated from operating activities. Employee headcount as of September 24, 2023 was approximately 17,200.

RESULTS OF OPERATIONS

Revenue

Revenue for the September 2023 quarter increased 9% from the June 2023 quarter primarily as a result of increased investments in the DRAM segment as well as increased spending by our China customers for mature node equipment.

Lam Research Corporation 2024 Q1 10-Q 19

The following table presents our revenue disaggregated between system 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 for the three months ended September 24, 2023 as compared to the same period in 2022, is primarily due to decreases in NAND spending by our customers during this time period.

Gross Margin

Gross margin as a percentage of revenue was higher in the September 2023 quarter compared to the June 2023 quarter primarily due to favorable customer mix partially offset by unfavorable factory absorption costs.

The increase in gross margin as a percentage of revenue in the three months ended September 24, 2023 compared to the same period in the prior year was primarily due to favorable customer mix as well as reduced spending on material costs, freight and logistics, partially offset by unfavorable factory utilization.

Research and Development

We continued to make significant R&D investments in the September 2023 quarter focused on leading-edge deposition, etch, clean and other semiconductor manufacturing processes. The increase in R&D expense in the September 2023 quarter compared to the June 2023 quarter was primarily driven by increases in supplies and employee-related costs, partially offset by a decrease in deferred compensation plan-related costs.

The decrease in R&D expense in the three months ended September 24, 2023 compared to the same period in the prior year was primarily driven by a decrease in outside service spending and lower employee-related costs.

Lam Research Corporation 2024 Q1 10-Q 20

Selling, General, and Administrative

SG&A expense during the September 2023 quarter increased in comparison to the June 2023 quarter, primarily driven by an increase in employee-related costs.

SG&A expense during the three months ended September 24, 2023 is flat to the same period in the prior year.

Restructuring Charges, Net

During fiscal year 2023, we initiated a restructuring plan designed to better align our cost structure with our outlook for the economic environment and business opportunities. Under the plan we terminated approximately 1,650 employees, incurring expenses related to employee severance and separation costs. Employee severance and separation costs primarily relate 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 charges in the September 2023 quarter decreased compared to the June 2023 quarter, due to the timing of employee separation activities. No restructuring charges were recognized during the three months ending September 25, 2022.

During the three months ended September 24, 2023 net restructuring costs of $7.9 million and $2.0 million were recorded in restructuring charges, net - cost of goods sold, and restructuring charges, net - operating expenses, respectively in our Condensed Consolidated Financial Statements, included in Part I of this Form 10-Q. Please refer to Note 15, “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 increased in the September 2023 quarter as compared to the June 2023 quarter, primarily due to higher average yields partially offset by lower average cash balances. Interest income increased for the three months ended September 24, 2023, compared to the same period in 2022, because of higher average yields and higher average cash balances.

Interest expense is consistent across all periods presented.

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

Lam Research Corporation 2024 Q1 10-Q 21

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

The losses in other, net for the September 2023 quarter were lower compared to the June 2023 quarter, primarily driven by fluctuations in the fair market value of equity investments. The losses in other, net for the three months ended September 24, 2023, were flat compared to same period in 2022.

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 September 2023 quarter compared to the June 2023 quarter was primarily due to the change in level and proportion of income in higher and lower tax jurisdictions, and the recognition of previously unrecognized tax benefits from lapses of statutes of limitation in the June 2023 quarter.

The effective tax rate for the September 2023 quarter compared to the same period in the prior year remained consistent.

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 2023 Form 10-K for additional information.

On August 16, 2022, the IRA was signed into law. In general, the provisions of the IRA are effective beginning with our fiscal year 2024, with certain exceptions. The IRA includes a new 15% corporate minimum tax. We have evaluated the potential impacts of the IRA and do not expect it to have a material impact on our effective tax rate. However, we expect future guidance from the Treasury Department and will further analyze when the guidance is issued.

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

A critical accounting policy is defined as one that has both a material impact on our financial condition and results of operations and requires us to make difficult, complex and/or subjective judgments, often as a result of the need to make estimates about matters that are inherently uncertain. The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make certain judgments, estimates and assumptions that could affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. We base our estimates and assumptions on historical experience and on various other assumptions we believe to be applicable and evaluate them on an ongoing basis to ensure they remain reasonable under current conditions. Actual results could differ significantly from those estimates, which could have a material impact on our business, results of operations, and financial condition. Our critical accounting estimates include:

• the recognition and valuation of revenue from arrangements with multiple performance obligations which impacts revenue;

• the valuation of inventory, which impacts gross margin;

• the recognition and measurement of current and deferred income taxes, including the measurement of uncertain tax positions, which impact our provision for income tax expenses; and

• the valuation and recoverability of long-lived assets, which impacts gross margin and operating expenses when we record asset impairments or accelerate their depreciation or amortization.

Refer to our “Critical Accounting Policies and Estimates” included in Part II, Item 7 of our 2023 Form 10-K for a discussion of the critical accounting estimates identified above.

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, investments, and restricted cash and investments balances were $5.2 billion at September 24, 2023 compared to $5.6 billion as of June 25, 2023. This decrease was primarily driven by $843.2 million of share repurchases, including net share settlement on employee stock-based compensation; $253.1 million of repayment of debt largely associated with the purchase of certain properties under finance leases; and $230.3 million in dividends paid; partially offset by $951.2 million of cash generated from operating activities.

Net cash provided by operating activities of $951.2 million during the three months ended September 24, 2023, consisted of (in thousands):

Significant changes in operating asset and liability accounts, net of foreign exchange impact, included the following uses of cash: decreases in deferred profit of $100.1 million, and accrued expenses and other liabilities of $39.8 million, along with an increase in prepaid expenses and other current assets of 43.8 million. The uses of cash are offset by the following sources of cash: increase in accounts payable of $53.5 million along with decreases in inventory of $51.7 million and accounts receivable of $9.0 million.

Cash Flow from Investing Activities

Net cash used for investing activities during the three months ended September 24, 2023, was $74.7 million, primarily consisting of $77.0 million in capital expenditures, partially offset by proceeds from maturities of available-for-sale securities of $7.3 million.

Cash Flow from Financing Activities

Net cash used for financing activities during the three months ended September 24, 2023, was $1.3 billion, primarily consisting of $843.2 million in treasury stock repurchases, including net share settlement on employee stock-based compensation, $253.1 million of repayment of debt, largely associated with the purchase of certain properties under finance leases, and $230.3 million in dividends paid.

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, cash equivalents, and short-term investments as of September 24, 2023, 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.

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.

Lam Research Corporation 2024 Q1 10-Q 23

For financial market risks related to changes in interest rates, marketable equity security prices, and foreign currency exchange rates, refer to Part II, Item 7A, “Quantitative and Qualitative Disclosures About Market Risk”, in our 2023 Form 10-K. Our exposure related to market risk has not changed materially since June 25, 2023.

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 September 24, 2023, 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 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, 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 13 “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

The Semiconductor Capital Equipment Industry Is Subject to Variability and Periods of Rapid Growth or Decline; We Therefore Face Risks Related to Our Strategic Resource Allocation Decisions

The semiconductor capital equipment industry has historically been characterized by rapid changes in demand. Variability in our customers’ business plans may lead to changes in demand for our equipment and services, which could negatively impact our results. The variability in our customers’ investments during any particular period is dependent on several factors, including but not limited to electronics demand, economic conditions (both general and in the semiconductor and electronics industries), industry supply and demand, prices for semiconductors, and our customers’ ability to develop and manufacture increasingly complex and costly semiconductor devices. The changes in demand may require our management to adjust spending and other resources allocated to operating activities.

During periods of rapid growth or decline in demand for our products and services, we face significant challenges in maintaining adequate financial and business controls, management processes, information systems, and procedures for training, assimilating, and managing our workforce, and in appropriately sizing our supply chain infrastructure and facilities, work force, and other components of our business on a timely basis. If we do not adequately meet these challenges during periods of increasing or declining demand, our gross margins and earnings may be negatively impacted.

We continuously reassess our strategic resource allocation choices in response to the changing business environment. If we do not adequately adapt to the changing business environment, we may lack the infrastructure and resources to scale up our business to meet customer expectations and compete successfully during a period of growth, or we may expand our capacity and resources too rapidly and/or beyond what is appropriate for the actual demand environment, resulting in excess fixed costs.

Especially during transitional periods, resource allocation decisions can have a significant impact on our future performance, particularly if we have not accurately anticipated industry changes. Our success will depend, to a significant extent, on the ability of our executive officers and other members of our senior management to identify and respond to these challenges effectively.

Future Declines in the Semiconductor Industry, and the Overall World Economic Conditions on Which It Is Significantly Dependent, Could Have a Material Adverse Impact on Our Results of Operations and Financial Condition

Our business depends on the capital equipment expenditures of semiconductor manufacturers, which in turn depend on the current and anticipated market demand for integrated circuits. With the consolidation of customers within the industry, the semiconductor capital equipment market may experience rapid changes in demand driven both by changes in the market generally and the plans and requirements of particular customers. The economic, regulatory, political, and business conditions occurring nationally, globally, or in any of our key sales regions, which are often unpredictable, have historically impacted customer demand for our products and normal commercial relationships with our customers, suppliers, and creditors. Additionally, in times of economic uncertainty, our customers’ budgets for our products, or their ability to access credit to purchase them, could be adversely affected. This would limit their ability to purchase our products and services. As a result, changing economic, regulatory, political or business conditions can cause material adverse changes to our results of operations and financial condition, including but not limited to:

• a decline in demand for our products or services;

• an increase in reserves on accounts receivable due to our customers’ inability to pay us;

• an increase in reserves on inventory balances due to excess or obsolete inventory as a result of our inability to sell such inventory;

• valuation allowances on deferred tax assets;

• restructuring charges;

• asset impairments including the potential impairment of goodwill and other intangible assets;

• a decline in the value of our investments;

Lam Research Corporation 2024 Q1 10-Q 25

• exposure to claims from our suppliers for payment on inventory that is ordered in anticipation of customer purchases that do not come to fruition; and

• challenges maintaining reliable and uninterrupted sources of supply.

Fluctuating levels of investment by semiconductor manufacturers may materially affect our aggregate shipments, revenues, operating results, and earnings. Where appropriate, we will attempt to respond to these fluctuations with cost management programs aimed at aligning our expenditures with anticipated revenue streams, which sometimes result in restructuring charges. Even during periods of reduced revenues, we must continue to invest in R&D and maintain extensive ongoing worldwide customer service and support capabilities to remain competitive, which may temporarily harm our profitability and other financial results.

We Have a Limited Number of Key Customers

Sales to a limited number of large customers constitute a significant portion of our overall revenue, shipments, cash flows, collections, and profitability. As a result, the actions of even one customer may subject us to variability in those areas that is difficult to predict. In addition, large customers may be able to negotiate requirements that result in decreased pricing, increased costs, and/or lower margins for us and limitations on our ability to share technology with others. Similarly, significant portions of our credit risk may, at any given time, be concentrated among a limited number of customers so that the failure of even one of these key customers to pay its obligations to us could significantly impact our financial results.

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 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
