What changed in Lam Research's 10-K for the fiscal year ended June 28, 2026

Tariffs, export controls, additional taxes, trade barriers, sanctions, the termination or modification of trade agreements, trade zones, and other duty mitigation initiatives, and any reciprocal retaliatory actions, can increase our manufacturing costs, decrease margins, reduce the competitiveness of our products, disrupt our supply chain operations, or inhibit our ability to sell products or provide services, all of which has had and in the future could have a material adverse effect on our business, results of operations, or financial condition. For example, our business requires steel and aluminum to manufacture our products, and the imposition of tariffs on steel and aluminum imports into the United States increased our manufacturing costs in fiscal year 2026, which adversely impacted our margins. Certain of our international sales depend on our ability to obtain export licenses from the U.S. or foreign governments. Our inability to obtain such licenses, or an expansion of the number or kinds of sales for which export licenses are required, has limited and could in the future further limit the market for our products and has had and could in the future have an adverse impact on our revenues. As is discussed below under the heading "Our Sales to Customers in China, a Significant Region for Us, Have Been Impacted, and are Likely to Be Materially and Adversely Affected by Export License Requirements and Other Regulatory Changes, or Other Governmental Actions in the Course of the Trade Relationship Between the U.S. and China," the U.S. government has in recent years imposed new controls, including expanded export license requirements and restrictions on sales to certain Chinese entities that significantly impact trade with China. In addition, the U.S. government has an ongoing process of assessing technologies that may be subject to new or additional export controls, and it is possible that such additional controls, if and when imposed, could further adversely impact our ability to sell our products outside the United States. The implementation by the U.S. government of broad export controls restricting access to our technology (such as recent controls limiting exports to China) may cause customers with international operations to reconsider their use of and reliance on our products, which could adversely impact our future revenue and profits and strengthen competitors who are not subject to such restrictions. Furthermore, there are risks that foreign governments may, among other things, take retaliatory actions; insist on the use of local suppliers; compel companies to partner with local companies to design and supply equipment on a local basis, requiring the transfer of intellectual property rights and/or local manufacturing; utilize their influence over their judicial systems to respond to intellectual property disputes or issues; and provide special incentives to government-backed local customers to buy from local competitors, even if their products are inferior to ours; all of which could adversely impact our ability to compete as well as our revenues and margins. For example, China is the primary source of supply of certain rare earth elements critical to the manufacture of certain of our products. [added] The Chinese government has imposed export controls and license requirements on certain rare earth elements and on certain products that contain Chinese-origin rare earth elements that are manufactured outside of China (which have been suspended in part until November 2026 (unless extended)) and could expand such controls or licensing requirements in the future. Such measures could delay or prevent our suppliers from sourcing the materials, or producing the components, required for us to manufacture our products, and increase the costs of such materials or components. In addition, to the extent these controls require us to obtain export licenses for certain products manufactured outside of China, we would experience increased compliance burdens, may be unable to obtain the required licenses, and may be unable to obtain materials or components necessary to meet our production requirements or product specifications in a timely manner, or at all, or on commercially acceptable terms. The occurrence of any of these risks could materially and adversely affect our business, results of operations, financial condition, and margins.

The technology, data, intellectual property and other sensitive information we seek to protect, and the information systems used to store, process, or transmit such information, are subject to loss, unauthorized access, unauthorized release, misappropriation, misuse, disruption, breach, degradation, or failure, any of which could have a material adverse effect on our business or operations. Such events may result from various possible causes, including mistakes or unauthorized actions by our employees, contractors, or other third parties, or cyberattacks or other malicious activities by third parties, including industrial, corporate, or other espionage, criminal hackers, or state-sponsored intrusions, by methods that include exploitation of known or unknown software or hardware vulnerabilities, viruses, malware, ransomware, social engineering (such as phishing schemes), credential harvesting, denial of service attacks, destructive or inadequate code, software or hardware failure, power failures, or physical damage to computers, hard drives, communication lines, or networking equipment, in each case with respect to us or the third-party product and service providers upon which we rely. We or our third-party product and service providers may not be able to anticipate, identify, or implement effective preventive measures against cyberattacks or data security incidents and, even if timely identified, we or our third-party product and service providers may not be able to remediate such attacks or incidents in a timely and effective manner, or to mitigate or avoid adverse impacts resulting from any such attacks or incidents. [added] These threats continue to evolve and may include the use of tools and techniques that change frequently or may be disguised or difficult to detect, or designed to circumvent security controls, evade detection, or remove forensic evidence, or remain dormant until a triggering event, or that may continue undetected for an extended period of time, which may hinder our or our third-party product and service providers' ability to identify, investigate, and remediate attacks or incidents in a timely and effective manner, or to mitigate or avoid adverse impacts resulting from any such attacks or incidents. In addition, the development and deployment of AI models, tools, and other applications expose us, our customers, suppliers, and other third-party providers to increased and novel risks and vulnerabilities, including prompt injection, hallucinations, errors, and other issues related to AI agents, as well as the risk of compromise of valuable intellectual property. For example, the autonomous nature of agentic AI increases the risk that agents learn to circumvent security controls, and certain generative AI systems and large language models may, in order to satisfy user prompts, access or retrieve data using the credentials, permissions, or access rights of the user or connected systems, which may increase the risk of unauthorized access, data leakage, or improper use of sensitive or proprietary information. To the extent AI capabilities improve and are increasingly adopted, they may be used to introduce, identify, or exploit vulnerabilities and to implement increasingly sophisticated cybersecurity attacks and could materially and adversely impact our business or operations. In addition, even if we or our third-party product and service providers are able to develop patches or other mitigations to address newly identified vulnerabilities, the pace at which AI enables the discovery and exploitation of such vulnerabilities may exceed our or our third-party product and service providers' ability to implement such patches and mitigations quickly enough to prevent the exploitation of such vulnerabilities.

[added] • any disruption to our relationship with, or loss of business from, customers, including due to actual or alleged non-compliance with contractual or other customer requirements, applicable laws, rules, or regulations, or breaches of customer trust;

We are subject to various risks in the jurisdictions in which we operate related to (1) new, different, inconsistent, or even conflicting laws, rules, and regulations that may be enacted by legislative or executive bodies and/or regulatory agencies; (2) disagreements or disputes related to international trade; and (3) the interpretation and application of laws, rules, and regulations. As a public company with global operations, we are subject to the laws of multiple jurisdictions and the rules and regulations of various governing bodies, including, but not limited to, those related to import and export controls and other trade restrictions, national and economic security (including receipt or use of designated technologies), intellectual property rights, taxes, financial and other disclosures, corporate governance, data protection, privacy, anti-corruption, such as the Foreign Corrupt Practices Act and other local laws prohibiting corrupt payments to governmental officials, anti-boycott compliance, conflict minerals or other social responsibility legislation, immigration or travel regulations, antitrust regulations, foreign ownership and investment, employment and labor, product and manufacturing regulations, environmental, health, and safety requirements, human rights, and laws or regulations relating to carbon emissions, such as the recent reporting requirements imposed by the State of California that require companies to provide climate-related disclosures, as well as other laws or regulations imposed in response to climate change concerns, among others. [added] Each of these laws, rules, and regulations imposes costs on our business, including financial costs and our management's attention associated with compliance, that could adversely impact our competitive position and our ability to meet customer demand. There have been, and may continue to be, instances of our compliance policies and procedures not being effective to ensure full compliance with all of the laws, rules and regulations to which we are subject. Such instances of non-compliance have presented and may present risks to our business, including the risk of legal, administrative, or regulatory proceedings, claims, demands, inquiries or investigations, fines, criminal penalties, restrictions on our actions or conduct of our business, loss of customer trust, and reputational damage. The occurrence of any of these risks could materially and adversely affect our business, financial condition, and/or results of operations.

[added] In March 2026, we increased the issuance capacity under our commercial paper program (the "CP Program") from $1.50 billion to $2.00 billion. The net proceeds from the CP Program may be used for general corporate purposes, including repurchases of our Common Stock from time to time under our stock repurchase program. As of June 28, 2026, we had no outstanding borrowings under the CP Program.

[added] The Organization for Economic Co-operation and Development's Base Erosion and Profit Shifting 2.0 ("BEPS 2.0") GMT was fully effective for us this fiscal year. We assessed GMT under currently enacted legislation and determined that we met transitional safe harbor requirements in most jurisdictions, with limited jurisdictions subject to GMT. We assessed the impact and concluded that it was not material. The impact has been included within income tax expense in fiscal year 2026.

[added] We present our revenues disaggregated by geographic region based on the location of customers' facilities to which products were shipped and services were rendered. A significant portion of our revenue is generated outside of the United States.

[added] The increase of $781.1 million in net cash used for financing activities during fiscal year 2026 compared to fiscal year 2025 was primarily the result of increased Common Stock repurchase activity, principal payments on debt instruments resulting from maturities of our 2026 Senior Notes, and higher dividends paid associated with an increased dividend rate.

There is inherent [added] risk that political, diplomatic and national security influences can lead to trade disputes, impacts and/or disruptions, in particular those affecting the semiconductor industry. This can adversely affect our business [added] in China, Japan, Korea, and/or Taiwan and perhaps the entire Asia Pacific region or [added] worldwide. A significant trade dispute, impact, and/or disruption in any area where we do business could have a materially adverse impact on our future [added] results of operations and cash flows. For example, the conflict that began in February 2026 between the United States, Israel, a number of states in the Persian Gulf, and Iran has led to significant regional instability and disruption in the Middle East, including the closure of or restrictions on the Strait of Hormuz, threatened or actual attacks on vessels in the Red Sea, and threatened or actual attacks on transportation and energy infrastructure, which has significantly and adversely affected the supply and prices of oil, refined oil products and byproducts, liquid natural gas, as well as certain other industrial commodities, such as aluminum, helium, bromine, and sulfur. Some of these commodities are important to the semiconductor industry. As a result, this instability and disruption has adversely affected, and may in the future materially and adversely affect, our business, results of operations, and financial condition. The extent to which we may be affected by this conflict will depend on various factors, including the scope, severity, and duration of the conflict and the extent to which the conflict, or additional laws, sanctions, or trade restrictions arising from or related to the conflict, further disrupt the availability or cost of critical inputs used in the semiconductor industry. Continuation or escalation of this conflict may also magnify the impact of other risks identified in this 2026 Form 10-K.

We have [added] $3.75 billion in aggregate principal amount of senior unsecured notes outstanding (the "Senior Notes"). Additionally, we have funding available to us under our [added] $2.00 billion commercial paper program and our [added] $2.00 billion revolving credit facility, which serves as a backstop to our commercial paper program. Our revolving credit facility also includes an option to increase the amount up to an additional $750.0 million, for a potential total commitment of $2.75 billion. We may, in the future, decide to enter into additional debt arrangements.

Total gross cash, cash equivalents, and restricted cash balances were [added] $5.60 billion at the end of fiscal year [added] 2026 compared to [added] $6.41 billion at the end of fiscal year [added] 2025. This decrease was primarily due to Common Stock repurchases in connection with our stock repurchase program, dividends paid, capital expenditures, and principal payments on debt [added] instruments, partially offset by cash provided by operating activities.

Please refer to Note 14, "Long-term Debt and Other Borrowings" to our Consolidated Financial Statements, included in Part II, Item 8 of this [added] 2026 Form 10-K for additional information.
