APPLIED MATERIALS, INC.

CONFLICT MINERALS REPORT

FOR YEAR ENDED DECEMBER 31, 2022

This is the Conflict Minerals Report of Applied Materials, Inc., including its subsidiaries (collectively, “Applied” or the “Company”), prepared in accordance with Rule 13p-1 under the Securities Exchange Act of 1934. Terms used in this report have the meaning specified in Rule 13p-l and/or Form SD issued by the Securities and Exchange Commission, except as otherwise expressly defined herein. Form SD defines “conflict minerals” as cassiterite, columbite-tantalite (coltan) and wolframite (and their derivatives, tin, tantalum and tungsten, respectively), and gold, regardless of the geographic origin of the minerals and whether or not they fund armed conflict. This report pertains to products manufactured from January 1 through December 31, 2022 for which any conflict minerals are necessary to the functionality or production of the product, as described further below.

Company Overview

A global company with a broad set of capabilities in materials engineering, Applied provides manufacturing equipment, services and software to the semiconductor, display, and related industries, and operates under three reportable segments: Semiconductor Systems, Applied Global Services, and Display and Adjacent Markets.

Applied Materials is committed to the responsible sourcing of materials used in our products and requires its direct suppliers to reasonably ensure products they sell to Applied do not contain conflict minerals unless these originated outside the Democratic Republic of the Congo or an adjoining country (collectively, the “DRC”) or from RMI “Conformant” sources within the DRC, as further defined below. Applied does not directly purchase raw ore or unrefined conflict minerals, nor does it have a direct relationship with any mines of origin or with any smelters or refiners (collectively, “smelters”) that process these minerals. Rather, Applied is a downstream company with an extensive and complex supply chain from which it purchases parts, components and assemblies (collectively, “Parts”). The Company’s manufacturing activities consist primarily of the assembly, testing and integration of various proprietary and commercial Parts that are used to manufacture systems. Applied has a distributed manufacturing model under which manufacturing and supply chain activities are conducted at its facilities, or those of contract manufacturers, located in various countries. Applied’s equipment products, due to their size and complexity, generally consist of thousands of Parts sourced from a multitude of suppliers. Applied relies on its direct suppliers to provide information on the origin of any conflict minerals contained in Parts they sell to the Company, including the source of conflict minerals they obtain from lower tier suppliers and smelters.

As detailed in this report, our approach to verifying the source and chain of custody of conflict minerals in our supply chain is designed to conform in all material respects with the OECD Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas: Third Edition and the related Supplements (“OECD Guidance”).

Products Covered by this Report

Tantalum, tin, tungsten and gold are metals commonly used in the electronics and related industries due to physical properties that make them well-suited for a variety of applications, such as in cables, printed circuit boards, power supplies, capacitors, solder alloys and certain plastics. As a result, all or substantially all of Applied’s equipment products, and many of its spare parts products, manufactured in 2022 include

1

components for which one or more conflict minerals are necessary to the functionality or production of the product and are therefore considered “Covered Products” for purposes of this report. The following is a general description of Covered Products by reporting segment.

Semiconductor Systems. Applied’s Semiconductor Systems segment develops, manufactures and sells a wide range of manufacturing equipment used to fabricate semiconductor chips, also referred to as integrated circuits (ICs). The Semiconductor Systems segment includes semiconductor capital equipment used for many steps of the chip making process including the transfer of patterns into device structures, transistor and interconnect fabrication, metrology, inspection and review, and packaging technologies for connecting finished IC die. The company’s platforms that perform these functions include: the Axcela^TM, Centris^®, Centura^®, Charger^TM, Endura^®, Mirra^®, Nokota^TM, Olympia^TM, P-300BV, Picosun^® Morpher, Producer^®, Raider^®, Radiance, Reflexion^®, Sprinter, Vantage^® and VIISta^® platforms. Applied’s metrology and inspection systems, which include the Enlight^®, PROVision^®, SEMVision^®, UVision^®, VeritySEM^® and Aera4^™ Mask Inspection systems, are used to locate, measure and analyze defects and features on the wafer during various stages of the fabrication processes. The majority of Applied’s new equipment sales are to leading integrated device manufacturers and foundries worldwide.

Applied Global Services. This segment provides integrated solutions to optimize equipment and fab performance and productivity, including spares, upgrades, services, remanufactured earlier generation equipment and factory automation software for semiconductor, display and other products.

Display and Adjacent Markets. This segment is comprised primarily of products for manufacturing liquid crystal displays (LCDs), organic light-emitting diodes (OLEDs), and other display technologies for TVs, monitors, laptops, personal computers (PCs), electronic tablets, smart phones and other consumer-oriented devices. While similarities exist between the technologies utilized in semiconductor and display fabrication, the most significant differences are in the size and composition of the substrate. Substrates used to manufacture display panels and other devices are typically glass, although newer flexible materials are entering the market. The Display and Adjacent Markets segment offers a variety of products and technologies, including: the AKT^® Electron Beam Array Test system for array test, AKT^® PECVD systems for CVD, AKT^® Aristo^™ and PiVot^™ systems for PVD, AKT^® TFE systems for thin-film encapsulation, and the AKT^® Electron Beam Review system for defect review.

Other Products. Applied’s Baccini^® systems are used for fabricating crystalline-silicon (c-Si) solar PV cells. Applied’s flexible coating systems, which include TopBeam^™, TopMet^™ and SmartWeb^®, utilize physical vapor deposition, thermal evaporation, chemical vapor deposition and e-beam technology to deposit thin layers of metal onto flexible substrates for packaging, flexible electronics and security industries.

Applied’s Conflict Mineral’s Compliance Program and Findings

Applied conducted in good faith a reasonable country of origin inquiry (“RCOI”) that it believes was reasonably designed to determine whether any of the necessary conflict minerals in its Covered Products manufactured in 2022 originated in the Democratic Republic of the Congo or an adjoining country (collectively, the “DRC”), or Conflict Affected High Risk Areas (CAHRAs), or were from recycled or scrap sources. Based on its RCOI, Applied determined it had insufficient information to conclude either (i) that all of its necessary conflict minerals originated outside the DRC or any CAHRAs or from sources within the DRC or any CAHRAs deemed “Conformant” by the Responsible Minerals Initiative (“RMI”), or (ii) that all of its necessary conflict minerals came from recycled or scrap sources.

Applied therefore undertook further due diligence on the source and chain of custody of necessary conflict minerals contained in its Covered Products. Its due diligence approach was designed to conform

2

in all material respects with the OECD Guidance. Since 2019, the Company has retained Assent Compliance (“Assent”), a third-party service provider, to assist Applied in conducting outreach to suppliers and evaluating the suppliers’ responses and their smelter engagements.

For calendar year 2022, Applied started with the list of surveyed suppliers for calendar year 2021 (211 suppliers) and added suppliers considered reasonably likely to provide Parts containing conflict minerals to arrive at a target list of suppliers to be contacted by Assent on behalf of Applied (the “Surveyed Suppliers”) (292 in total). The Surveyed Suppliers represent approximately 77% of the Company’s actual total expenditures to all direct suppliers for fiscal year 2022.¹ Ninety-nine percent (99%) of the Surveyed Suppliers responded. Approximately 22% of the responding Surveyed Suppliers provided product-level responses. Of the Smelters or Refiners that were reported by the Surveyed Suppliers, 8% used minerals that originated from 100% recycled or scrap sources.

The table below summarizes certain information pertaining to smelters identified by Surveyed Suppliers. The Responsible Minerals Initiative (“RMI”), of which Applied is a member, was founded by the Responsible Business Alliance (“RBA”), formerly the Electronics Industry Citizenship Coalition (“EICC”), and the Global eSustainability Initiative. Under the RMI, “Conformant” smelters are those smelters that are conformant with the Responsible Minerals Assurance Process (“RMAP”) assessment protocols. “Active” smelters and refiners are participants in the RMAP who have agreed in writing to undergo a third-party audit or are participating in one of the cross-recognized certification programs, signed an “Agreement for the Exchange of Confidential Information” and submitted a due diligence checklist. The classification of smelters considered Conformant or Active is current as of January 9, 2023.

As a result of its due diligence, Applied found evidence of potential sourcing from two gold smelters in the DRC (CID003185 - African Gold Refinery and CID002567 - Sudan Gold Refinery). These two smelters have not been assessed by the RMI. Information about these smelters was provided to Applied by fourteen Surveyed Suppliers as “product-level” responses, but these responses lacked a chain of custody and therefore were insufficient to tie gold from one or more of these smelters to products supplied to Applied. Applied found no direct evidence that minerals from these two smelters were incorporated into its Covered Products. Thus, it is uncertain whether these smelters are part of Applied’s supply chain.

In the past, the Company had instructed the affected Surveyed Suppliers to remove these two smelters from their supply chains and to require their relevant sub-tier suppliers to request the smelters to join the RMAP. However, many Surveyed Suppliers have no direct relationship with the smelters and are merely reporting information they received from their suppliers. Therefore, the Company’s Responsible Minerals Sourcing Team is contacting these smelters directly, as well as other smelters reported by the Surveyed Suppliers that are not RMI Conformant or Active; Assent is contacting the smelters on behalf of Applied; and the Company is also contacting the smelters via working groups within the RMI, urging them to submit to an RMI assessment and conform to the RMAP.

Attached as Appendix A is a list of the smelters or refiners identified by the Surveyed Suppliers as the facilities that process conflict minerals necessary to their products. Since the majority of the Surveyed Suppliers reported smelter information at the company level and not at the product level, and they did not identify the specific smelter that processed conflict minerals contained in a particular Part, we do not know with certainty that each smelter or refiner listed in Appendix A processed minerals that were used in the

3

Parts we purchased. However, as an improvement over prior years, a growing number of Surveyed Suppliers submitted product specific Conflict Minerals Reporting Templates (“Templates”) (63 of the 292 Surveyed Suppliers who responded to our due diligence request).

For the significant majority of smelters reported by the Surveyed Suppliers, there is inadequate information available to assess the source of the conflict minerals they process. Therefore, for Covered Products manufactured in 2022, Applied concluded in good faith that it lacks sufficient information to trace the chain of custody of any conflict minerals contained in its Covered Products up through the supply chain to a specific smelter or, in turn, to a country or mine of origin.

Applied’s Due Diligence Process

Applied’s due diligence approach on the source and chain of custody of its necessary conflict minerals was designed to conform in all material respects with the OECD Guidance. The OECD Guidance is an internationally recognized due diligence framework consisting of a multi-step, risk-based process, certain aspects of which differ depending in part on the position of a company in the supply chain. Applied is a “downstream” company, which refers to supply chain participants from the smelter to the retailer, in contrast to those “upstream,” that is, from the mine to the smelter.

As a downstream provider of finished products, Applied does not have direct relationships with smelters and does not perform or specify audits of such entities upstream in its supply chain. Through its membership and participation in the RBA, RMI and related working groups, Applied believes that seeking reliable information about smelters in its supply chain from its direct suppliers represents a reasonable and cost-effective approach to determine the mines or other locations of origin of conflict minerals in its products.

Company Management System

Applied established a cross-functional Responsible Minerals Sourcing Compliance Team, which is responsible for implementing the Company’s Responsible Minerals Sourcing program and briefing senior management about the results of these due diligence efforts. As noted above, Applied uses Assent to assist with evaluating supply chain information regarding conflict minerals, identifying potential risks and developing appropriate mitigation strategies. In addition, Applied leverages Assent’s Managed Services and works with dedicated program specialists to support and improve Applied’s Responsible Minerals Sourcing program.

The Company expects its suppliers to have programs and procedures in place to ensure that any conflict minerals used in the production of products sold to Applied conform to the requirements of the RMI. This means that products must not contain conflict minerals that directly or indirectly finance or benefit armed groups in the DRC. In addition, as a member of the RBA, Applied requires its suppliers to conform to the RBA Code of Conduct, which includes requirements pertaining to the responsible sourcing of conflict minerals. Such requirements, along with a requirement that suppliers provide completed Conflict Minerals Reporting Templates at Applied’s request, also are reflected in supplier contracts. If Applied learns that a Surveyed Supplier does not meet the Company’s requirements, Applied pursues appropriate corrective action.

Violations or grievances related to conflict minerals can be reported at the industry level to the RMI at http://www.responsiblemineralsinitiative.org/.

Applied retains relevant documentation for a period of five years, including Templates completed by the Surveyed Suppliers.

Risk Identification and Assessment

In light of the complexity of its supply chain, Applied used a risk-based approach in designing the scope of its RCOI and due diligence process. As previously noted, the Company focused on direct suppliers who previously indicated the products they provide to Applied contain conflict minerals, and then added suppliers considered reasonably likely to provide Parts containing conflict minerals, to arrive at the target list of Surveyed Suppliers. Assent conducted the outreach to the Surveyed Suppliers with support from Applied’s Responsible Minerals Sourcing Compliance Team. Applied then compared information provided by the Surveyed Suppliers with data from RMI concerning the RMAP audit status of the applicable smelter or refiner.

The Conflict Minerals Reporting Template (the “Template”) developed by the RMI was used to collect information on the conflict minerals that may be in Covered Products manufactured in 2022. The Template was designed to facilitate a supplier’s disclosure of information regarding conflict minerals contained in the supplier’s products, including the country of origin and the name and location of the smelters that process the conflict minerals. Using the Assent Sustainability Manager (“ASM”), a software-as-a-service platform provided by Assent, Assent and Applied contacted the Surveyed Suppliers and requested them to complete the Template with respect to Parts they supplied to Applied and to upload their completed Templates directly to the platform for validation, assessment and management. The ASM provides functionality that meets the OECD Guidance process expectations by evaluating the quality of each supplier response to increase the accuracy of submissions.

Risks at the supplier level may include non-responsive suppliers, incomplete Templates or Templates that are submitted at the company level and are not directly relevant to products manufactured by Applied. Applied received wholly or partially completed Templates from 99% of its Surveyed Suppliers. The majority of the responding Surveyed Suppliers provided data at a company or “user defined” level, rather than at a part number level, a permitted option under the Template. Those suppliers who reported at a user defined level reported data at the business division level. As noted above, approximately 22% of the Surveyed Suppliers submitted data at a part number level.

Applied worked with Assent to assess the status of smelters and refiners identified in the supply chain by the Surveyed Suppliers who listed mineral processing facilities in their Templates. Each identified smelter or refiner of a conflict mineral is assessed according to red-flag indicators defined in the OECD Guidance. These factors include geographic proximity to the DRC, known mineral source country of origin, RMAP audit status, credible evidence of unethical or conflict sourcing and peer assessments conducted by credible third-party sources. Such smelters are labeled smelters of interest. Applied then used Assent’s findings to determine which Surveyed Suppliers required further engagement, such as those who reported “red-flag smelters” or who provided incomplete, untimely or inconsistent information, and made further inquiries of those suppliers.

Applied was not required to, and it did not, obtain an independent private sector audit of its due diligence approach.

Risk Mitigation Strategy and Future Due Diligence

Risk mitigation activities included asking Surveyed Suppliers to provide product specific Templates. In addition, in 2022, the Company supported approximately 17 smelters undergoing RMI assessments to retain their “Conformant” status.

5

We refined our due diligence efforts during calendar year 2022: we increased the number of Surveyed Suppliers by approximately 38% in comparison to the prior year by including suppliers who sell products to Applied that do contain conflict minerals:

Applied intends to improve its ability to identify suppliers reasonably likely to provide Parts containing conflict minerals as well as its ability to link the smelter information its suppliers report to specific products they supply to Applied by requiring suppliers to provide product level Templates for tantalum target, gold plating and special process parts and continuing to work with Assent to improve the quality of data submitted by the suppliers. Applied further has undertaken to report relevant smelter information it obtains to RMI, and to encourage its suppliers to reach out (or to encourage their own suppliers to reach out) to upstream smelters that provide them with conflict minerals and require that such smelters obtain a “conflict-free” designation from an industry program such as the RMAP. To this end, Applied and Assent, on behalf of Applied, will continue to communicate directly with smelters reported by the Surveyed Suppliers who have not yet been deemed conformant with the RMAP to request sourcing information and encourage the smelters to engage with the RMAP program. Applied is a co-chair of the RMAP Smelter Engagement Team, which contacts smelters and assists them with undergoing RMAP assessments to validate the smelters’ company-level management processes for responsible minerals procurement. Such engagement is expected to increase participation and retention of the smelters in the RMAP program. In addition, the Company is exploring other opportunities for increasing the use of recycled minerals in products it purchases.
