Exhibit 1.01
KLA Corporation
Conflict Minerals Report for the
Reporting Period from January 1, 2023 to December 31, 2023

Introduction
This Conflict Minerals Report for KLA Corporation (“KLA”, “Company”, “we,” or “our”) for the reporting period from January 1, 2023 to December 31, 2023 is presented to comply with Rule 13p-1 under the Securities Exchange Act of 1934 (the “Rule”). The Rule was adopted by the Securities and Exchange Commission (the “SEC”) to implement reporting and disclosure requirements related to conflict minerals (as that term is defined below) as directed by the Dodd-Frank Wall Street Reform and Consumer Protection Act. The Rule imposes certain reporting obligations on each U.S. publicly traded company whose manufactured products contain columbite-tantalite, cassiterite, wolframite (or their derivatives tantalum, tin and tungsten, respectively), or gold (collectively referred to as “conflict minerals,” regardless of their geographic origin and whether or not they fund armed conflict in the Democratic Republic of Congo or adjoining countries (collectively, the “Covered Countries”)) that are necessary to the functionality or production of the company’s products. In summary, the Rule requires each of these U.S. publicly traded companies to conduct a reasonable inquiry with respect to the sourcing of the conflict minerals that such company uses in its products and file a description of the inquiry performed and the results of such inquiry. If a company determines or has reason to believe that these conflict minerals may have originated or did originate from the Covered Countries, and were not or may not be derived from scrap or recycled sources, the Rule requires such company to exercise due diligence on the source and chain of custody of the conflict minerals, including making an effort to determine whether trade in these minerals directly or indirectly finances or benefits armed groups in the Covered Countries, and to provide a Conflict Minerals Report as an exhibit to its Form SD.
KLA is committed to complying with the Rule. KLA does not have a direct relationship with conflict minerals smelters or refiners. Accordingly, with respect to the classification and certification of smelters and refiners, we have relied upon the activities, conclusions and reporting from the Responsible Business Alliance Responsible Minerals Initiative (“RMI”) and Responsible Minerals Assurance Process (“RMAP”).
Company Business and Products for 2023
KLA is engaged primarily in the design, manufacture and marketing of process control and process-enabling solutions for the semiconductor and related nanoelectronics industries. We provide advanced process control and yield management solutions for manufacturing wafers and reticles, integrated circuits, packaging, light emitting diodes (LED), power devices, compound semiconductor devices, microelectromechanical systems, data storage products, printed circuit board (PCB), flat panel display (FPD) and general materials research. In addition, KLA’s SPTS division designs, manufactures, sells, and supports etch, physical vapor deposition (PVD), chemical vapor deposition (CVD) and molecular vapor deposition (MVD) capital equipment, providing advanced wafer processing technologies and solutions for the semiconductor and microelectronics industry. (See KLA Products in Appendix B)
Metals included in the definition of “conflict minerals” are generally used throughout electronic components for purposes necessary to their functionality. Therefore, we believe that KLA products contain conflict minerals that are necessary to the products’ functionality.
Reasonable Country of Origin Inquiry
We conducted a reasonable country of origin inquiry on the conflict minerals that are necessary to the functionality or production of our products that we manufactured, or contracted to manufacture, during the reporting period.
We have worked with certain third-party service providers to contact the suppliers of components that potentially contain conflict minerals. We made reasonable efforts to determine the country of origin of the necessary conflict minerals used in the components these suppliers supplied to us for use in the products that we manufactured, or contracted to manufacture, during the reporting period. We have required these suppliers to provide conflict minerals use and sourcing information in the form of the RMI Conflict Minerals Reporting Template (the “Template”). Some suppliers provided responses with information for their company as a whole rather than the specific components that we purchase from them (referred to as the “declaration scope” within the Template). In those instances, the exact mapping of a supplier’s sourcing statements to our specific components was less certain. For example, if a supplier that manufactured many different components had produced only one
1


component that contained necessary conflict minerals that were not found to be conflict-free, this would tend to also be the supplier’s conclusion at their company level, even if the vast majority of their other products were otherwise conflict-free.
Pursuant to the Rule, we undertook due diligence on the source and chain of custody of the necessary conflict minerals in our products that we had reason to believe, based on our suppliers’ responses, may have originated from the Covered Countries and may not have come from scrap or recycled sources.
Design of Conflict Minerals Program
We designed our conflict minerals program to be in conformance with the Organization for Economic Co-operation and Development (“OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas Third Edition and related Supplements on Tin, Tantalum and Tungsten and on Gold (collectively, the “OECD Guidance”). Summarized below are the design components of our conflict minerals program as they relate to the five-step framework set forth in the OECD Guidance.
1.Establish strong company management systems:
a.Publicly communicate our conflict minerals sourcing policy on our corporate website. Please see Section D of our Product Regulatory Compliance Guidelines under Supply Chain Product Compliance at https://www.kla.com/company/supplier. The content of any website referred to in this Conflict Minerals Report is included for general information only and is not incorporated by reference in this Conflict Minerals Report or in KLA’s Specialized Disclosure Report on Form SD.
b.Operate an internal management conflict minerals team led by our Corporate Procurement organization and supported by a cross-departmental team consisting of representatives of a number of internal groups, including Corporate Product Regulatory Compliance, Finance, Legal, Information Technology and Global Operations, as well as third-party service providers.
c.Hold regular meetings of our internal conflict minerals team and provide summaries of the status of the conflict minerals program to the Chief Financial Officer, Chief Accounting Officer, Chief Legal Officer, Senior Vice President of Global Operations and Head of Procurement (“Senior Management”).
d.Establish a system of controls and transparency over the mineral supply chain through the use of a third-party system and use recognized due diligence tools created by the RMI in the evaluation of supplier responses regarding smelters and refiners of necessary conflict minerals that may be used in our products.
e.Incorporate supply chain regulatory compliance requirements into our standard template for supplier contracts so that suppliers comply with our policy on conflict minerals.
f.Retain records in accordance with our internal record retention policy.
g.Establish a hotline and website for use by employees, as well as third parties such as suppliers and customers, to report actual or suspected wrongdoing or other grievances and answer questions about business conduct, including reports or questions regarding our use of conflict minerals. The hotline and website are both operated by an independent third party, which provides tools to enable individuals to submit reports in a number of different languages and, where permitted by law, on an anonymous basis.
2.Identify and assess risks in our supply chain:
a.Identify the suppliers that provide components that potentially incorporate conflict minerals that are necessary to the functionality or production of our products that we manufactured, or contracted to manufacture.
b.Contact the suppliers of components that potentially contain conflict minerals and use the Template to capture the suppliers’ responses.
c.Use reasonable efforts to determine the country of origin of the necessary conflict minerals used in the components our suppliers provided to us that are incorporated into the products that we manufactured, or contracted to manufacture, during the reporting period.
d.Contact the suppliers that did not respond to the Template request and request their responses.
e.Conduct due diligence on the source and chain of custody of the necessary conflict minerals in our products that we had reason to believe may have originated from the Covered Countries and may not have come from scrap or recycled sources. Compare responses provided against the list of smelters and refiners that have received a “conformant” designation from the RMAP. Document the country of origin information for the smelters and refiners identified by the supply chain responses using RMI data.
3.Design and implement a strategy to respond to identified risks:
2


a.Verify smelters and refiners identified in response to the Template against the RMI list provided as part of our membership in the RMI.
b.Report our findings to our internal management conflict minerals team, outlining the information gathered and the actual and potential identified risks and any required action plans. The action plans will vary depending on the results of our due diligence efforts and the risks identified in any particular year.
c.Implement required action plans and report results to Senior Management.
4.Independent third-party audits of smelters and refiners sourcing:
a.Participate in the RMI and rely upon the results reported by RMI regarding audits of smelters and refiners.
b.Provide to RMI the smelters and refiners identified by our suppliers that are not on the RMI list.
5.Report on supply chain due diligence:
a.Report to the SEC annually our supply chain due diligence on a Form SD and conflict minerals report.
b.Publicly communicate our Form SD and conflict minerals report on our website at https://ir.kla.com/sec-filings/all-sec-filings.
Due Diligence Performed
Our due diligence process consists of the systematic review and analysis of the responses that were provided to us by our suppliers, as well as communication and follow-up with our suppliers based on the results of our review, in an effort to identify the source and chain of custody of the conflict minerals necessary to our products. We initially screened supplier survey responses for completeness, accuracy and internal consistency. Where suppliers provided information that was incomplete or appeared incorrect, we sought additional data from such suppliers to clarify or correct the originally provided information. We compared the information provided by the suppliers’ responses to the Template against our applicable internal component descriptions to confirm consistency between the various data sources regarding the presence of conflict minerals. In the case of conflict minerals that may have originated in the Covered Countries, we reviewed the data contained in the applicable responses to the Template against RMI data to make a determination about the country of origin of the conflict minerals or about the related smelters and refiners. We used the RMI information to identify legitimate smelters and refiners and smelters and refiners that were either conformant to, or active in, or in communication with the RMAP.
We reported our findings to our internal management conflict minerals team in monthly management review meetings outlining the information gathered and the actual and potential identified risks and any required action plans and actions taken against those plans.
Facilities Used to Process Necessary Conflict Minerals
Appendix A is a list of the entities that were identified by our suppliers as the smelters or refiners that process the necessary conflict minerals in the suppliers’ products that either (a) are conformant with the RMI RMAP assessment (Section 1 of Appendix A) or (b) have been verified by RMI as smelters or refiners that are active in or are in communication with or require outreach to participate in the RMAP process assessment (Section 2 of Appendix A).
Since some of the declarations we received from our suppliers were at a company level (and not a component-specific level), we do not know with certainty that each smelter listed on Appendix A actually processed conflict minerals that were used in components we purchased. We also received responses from suppliers listing smelters or refiners that have not yet been verified as smelters or refiners by RMI. Additionally, we received responses that indicated that some conflict minerals were obtained from scrap or recycled sources.
Country of Origin of the Necessary Conflict Minerals
As of March 31, 2024, we have compared the facilities used to process the necessary conflict minerals as identified by our suppliers against the country of origin information provided by the RMI for RMAP-conformant smelters and refiners and determined we have reason to believe that some of our necessary conflict minerals may have originated in the Covered Countries. The countries of origin of the necessary conflict minerals that may be in our products and are listed in the RMI for RMAP-conformant smelters and refiners may include Albania, Andorra, Angola, Argentina, Armenia, Australia, Austria, Azerbaijan, Belarus, Belgium, Benin, Bermuda, Bolivia (Plurinational State of), Botswana, Brazil, Bulgaria, Burkina Faso, Burundi, Cambodia, Canada, Central African Republic, Chile, China, Colombia, Congo, Cyprus, Democratic Republic of Congo, Djibouti, Dominica, Dominican Republic, Ecuador, Egypt, El Salvador, Eritrea, Estonia, Ethiopia, Fiji, Finland, France, Georgia, Germany, Ghana, Guam, Guatemala, Guinea, Guyana, Honduras, Hong Kong, Hungary, India, Indonesia, Ireland, Israel, Italy, Ivory Coast, Japan, Jersey, Kazakhstan, Kenya, Korea, Kyrgyzstan, Liberia, Liechtenstein, Lithuania,

Risk Mitigation/Improvements
The activities described above were intended to examine and mitigate the risk that our necessary conflict minerals benefited armed groups in the Covered Countries.
We made improvements over the previous reporting period by (a) continuing our membership in the RMI to obtain updated details regarding mines utilized by smelters conformant or not conformant with the RMAP; (b) identifying a greater percentage of smelters and refiners over that obtained in previous reporting periods; and (c) provided additional training and resources to our suppliers via web-based access through a third-party; and (d) improving the identification of high risk smelters of concern, assessing the supplier relationship and encouraging the supplier to take appropriate actions to find alternate acceptable sources of supply.
Through our due diligence we have identified smelters of concern that were reported by certain suppliers. These smelters were identified by our process as high risk smelters of concern due to not being listed as conformant by RMI and other factors such as their proximity to the Covered Countries, lack of a conflict minerals process and/or their alleged ties to human rights issues. In these cases, we have asked our suppliers to request that these smelters pursue certification with RMI or be removed from our supply chain. We do not source directly from these smelters of concern and because the conflict minerals information from many of these suppliers is presented as company-level responses (and not a component-specific level), it is uncertain that conflict minerals from these smelters are in our supply chain. Should these smelters decline to participate in an audit and our supplier refuses to remove these smelters from our supply chain, we will evaluate our relationship with that supplier and may explore alternatives. We are also a signatory to a letter that our third-party service provider initiates to all smelters identified as non-conformant as per the RMAP audit status, which encourages their participation in the program. In this communication, the smelters are provided explicit details about various RMI funding channels to help offset the costs of undergoing the audit and receiving certification.
We intend to take the following steps to further enhance our due diligence in future years: (a) improve our review of non-verified smelters and refiners; (b) work with suppliers to improve the accuracy and completeness of their responses; (c) continue our inclusion of new suppliers identified from new acquisitions; and (d) drive the sourcing of conflict free components in our design and engineering programs.
Forward-Looking Statements: Statements in this Conflict Minerals Report other than historical facts, such as statements regarding our intentions to investigate further details regarding mines utilized by smelters conformant with RMAP, improve our review of non-verified smelter and refiner names, work with our suppliers to improve the accuracy and completeness of their responses, and drive the sourcing of conflict free components in our design and engineering programs, are forward-looking statements, and are subject to the Safe Harbor provisions created by the Private Securities Litigation Reform Act of 1995. These forward-looking statements are based on current information and expectations, and involve a number of risks and uncertainties. Actual results may differ materially from those projected in such statements due to various factors, including but not limited to: our ability to use alternate suppliers; the inaccuracy of the information reported to us by our direct suppliers or industry information used by us; and the risk that smelters or refiners may not participate in the RMAP and that smelters listed as conformant by the RMAP does not necessarily mean that they were conformant for the whole reporting period and that some conformant statuses may have expired and that those smelters may/may not be in the process of a re-audit. For other factors that may cause actual results to differ materially from those projected and anticipated in forward-looking statements in this Conflict Minerals Report, please refer to the Company’s Annual Report on Form 10-K for the year ended June 30, 2023, subsequently filed Quarterly Reports on Form 10-Q and other filings with the SEC (including, but not limited to, the risk factors described therein). The Company assumes no obligation to, and does not currently intend to, update these forward-looking statements, except as required by law.
