Exhibit 1.01

Conflict Minerals Report of Materion Corporation

for the Reporting Period from January 1, 2020 to December 31, 2020

Overview

This Conflict Minerals Report (this “Report”) of Materion Corporation (including its consolidated subsidiaries, “we”, “Materion” or the “Company”) has been prepared pursuant to Rule 13p-1 (the “Rule”) as promulgated under the Securities Exchange Act of 1934 for the reporting period from January 1, 2020 to December 31, 2020 (the “Reporting Period”).

Forward-looking statements contained in this Report are made based on known events and circumstances at the time of release, and as such, are subject in the future to unforeseen uncertainties and risks. Statements in this Report which express a belief, expectation or intention, as well as those that are not historical fact, are forward-looking statements, including statements related to the Company’s compliance efforts and expected actions identified in this Report. These forward-looking statements are subject to various risks, uncertainties and assumptions, including, among other matters, the Company’s customers' requirements to use certain suppliers, the Company’s suppliers' responsiveness and cooperation with the Company’s due diligence efforts, the Company’s ability to implement improvements in its conflict minerals program and the Company’s ability to identify and mitigate related risks in its supply chain. If one or more of these or other risks materialize, actual results may vary materially from those expressed. For a more complete discussion of these and other risk factors, see the Company’s other filings with the Securities and Exchange Commission (“SEC”), including its Annual Report on Form 10-K for the year ended December 31, 2020 and subsequent Quarterly Reports on Form 10-Q. The Company makes these statements as of the date of this disclosure, and undertakes no obligation to update them unless otherwise required by law.

Rule 13p-1, through Form SD, requires the disclosure of certain information if a company manufactures or contracts to manufacture products for which certain “conflict minerals” (as defined below) are necessary to the functionality or production of such products. The SEC defines “conflict minerals” as: (i)(a) columbite-tantalite (or coltan, the metal ore from which tantalum is extracted), (b) cassiterite (the metal ore from which tin is extracted), (c) gold and (d) wolframite (the metal ore from which tungsten is extracted), or their derivatives, which are currently limited to tantalum, tin and tungsten; or (ii) any other mineral or its derivatives determined by the U.S. Secretary of State to be financing conflict in the Democratic Republic of the Congo or an “adjoining country,” as such term is defined in Section 1502 of the Dodd-Frank Wall Street Reform and Consumer Protection Act (collectively, the “Covered Countries”).

The Company’s operations may at times manufacture, or contract to manufacture, products for which conflict minerals are necessary to the functionality or production of those products (collectively, the “products”). As required by the Rule, the Company has conducted a good faith, reasonable country of origin inquiry (“RCOI”) regarding the conflict minerals included in the products during the Reporting Period to determine whether any such conflict minerals originated in the Covered Countries and/or whether any of the conflict minerals were from recycled or scrap sources. Where applicable, the Company has conducted additional due diligence regarding the sources of the conflict minerals. The results of the Company’s RCOI regarding the conflict minerals, as well as the Company’s additional due diligence regarding the sources of such conflict minerals, are contained in this Report, which is publicly available at www.materion.com. The content on, or accessible through, any web site referred to in this Report is not incorporated by reference into this Report unless expressly noted.

Description of Materion's Reasonable Country of Origin Inquiry

Materion has performed a good faith RCOI regarding the conflict minerals that were in our supply chain between January 1, 2020 and December 31, 2020 to determine whether any of the conflict minerals originated in the Covered Countries and whether any of the conflict minerals may be from recycled or scrap sources in accordance with the Rule and related guidance provided by the SEC.

The Company’s global supply chain is complex. In the course of its business operations, the Company may purchase materials and metals containing conflict minerals. These materials and metals may, in turn, be included in the Company’s products. Because the Company does not normally purchase conflict minerals directly from mines, smelters or refiners, there are many third parties in the supply chain between the Company and the original sources of conflict minerals. As a result, the Company relies on its direct suppliers to provide information regarding the origin of any conflict minerals that are included in its products. In accordance with the framework in the Organization for Economic Co-operation and Development Due Diligence Guidelines for Responsible Supply Chain of Minerals from Conflict-Affected and High Risk Areas: Third Edition, including the related supplements on gold, tin, tantalum and tungsten (the “OECD Guidelines”), and related guidance provided by the SEC, the Company worked with its direct suppliers to identify, where possible, the smelters and/or refiners and countries of origin of the conflict minerals.

Prior to and during the Reporting Period, the Company worked to identify current and new direct materials suppliers that it believed could potentially provide materials or metals containing conflict minerals (collectively, the “Identified Suppliers”). The Company then surveyed all the Identified Suppliers to determine whether each such Identified Supplier was supplying materials or metals to the Company that contained conflict minerals and, if so, to determine the source of such conflict minerals. The Company’s surveys required Identified Suppliers to, among other matters, confirm the source of any conflict minerals contained in materials or metals supplied to the Company and to provide any updates regarding such responses.

The Company, with respect to the Reporting Period, reasonably determined that certain of its products described above under “Overview” contain conflict minerals necessary to the functionality or production of such products.

For the Reporting Period, the Company sought and obtained representations from all 58 Identified Suppliers from whom the Company sought such representations. Such representations included, from all Identified Suppliers, Responsible Minerals Initiative (“RMI”) Conflict Minerals Reporting Template (“CMRT”) indicating the facility at which the conflict minerals were processed.

Based on the information obtained pursuant to the RCOI process described above, the Company has concluded, in good faith, that it does not have sufficient information with respect to the Reporting Period to determine the country of origin of all of the conflict minerals.

Due Diligence

For the Reporting Period, Materion performed due diligence from November 2020 through April 2021 to determine the source and chain of custody necessary to determine conflict minerals in the Company’s product offerings. Materion designed its due diligence measures to conform in all material respects with the OECD Guidelines and the Responsible Business Alliance’s Responsible Minerals Assurance Process ("RMAP"). This process included building conflict minerals awareness across the supply base and the survey of all Identified Suppliers that were known to or may have provided products containing metal and /or conflict minerals.

Materion occupies a “downstream” position in the supply chain and followed the principles outlined in the OECD Guidelines for downstream companies with no direct relationships to smelters or refiners. In this context, “downstream” refers to the supply chain from smelters and refiners to retailers and includes companies such as ours, as well as product and component manufacturers and retailers. A summary of Materion’s due diligence activities in line with the OECD Guidelines is outlined below.

Step 1: Establish strong company management systems:

•Materion has published an updated formal Responsible Minerals Sourcing Policy to address conflict minerals sourcing in the Covered Countries expanding the scope to include conflict-affected and high-risk areas ("CAHRAs") in accordance with UN resolutions with a pledge to purchase materials only from sources that are not involved in or contributing to illegal armed groups, human rights violators, or financial wrongdoings;

•Materion maintains a governance model to oversee the implementation and ongoing management of the Conflict Minerals Compliance Program. The governance model consists of two groups: The Steering Committee and the Core Team, and various work products. The objective is to develop, document and maintain a governance structure that enables sustainable compliance and actively mitigates the risk of not meeting regulatory requirements;

•Materion maintains a process to evaluate raw materials, parts and suppliers in the supply chain for potential conflict minerals risk;

•Materion communicates its policy regarding the responsible sourcing of conflict minerals to all existing and new suppliers including through language incorporated in supplier contracts, agreements, flow down language in all United States Government contracts and the Materion Supplier Code of Conduct.

Additionally, wording has been added to supplier contracts and written agreements including the right to conduct unannounced spot-checks;

•Materion continues to leverage SAP and other enterprise resource planning ("ERP") systems and Quality Management procedural controls to prevent transactions with non-conforming conflict mineral suppliers;

•Materion has established long-term relationships with suppliers and closely manages the pool of suppliers eligible to be utilized; and

•Materion will continue to refer to RMI’s Grievance Mechanism to collect information on grievances for all interested parties to provide information or voice their concerns regarding its sourcing and use of conflict minerals in its products.

Step 2: Identify and assess risks in the supply chain:

•On an annual basis, Materion evaluates raw materials and parts that are known or are likely to contain conflict minerals using a risk-based approach;

•Each compliance year, Materion requires identified suppliers to provide a CMRT. Materion has a 100% response rate for six consecutive years;

•Materion engages Identified Suppliers in one-on-one individualized capability training in order to build their capabilities and to enable them to improve their understanding of the regulation and their responsibility as a Materion supplier;

•Materion conducts a review of supplier responses to determine that all required questions and sections of the CMRT were completed, follows up with any supplier that did not complete all required questions, and verifies the CMRT had an acceptable Effective Date and appropriate CMRT version;

•Materion reviews the survey responses and validates them for completeness and sufficiency;

•Materion reviews aggregated supplier survey responses and reports key metrics as part of the monthly conflict minerals reporting process; and

•Materion conducts an annual review of summary smelter information to determine if the smelter is certified as conformant or presented a "red flag" as defined by the OECD Guidelines. To make the determination of each smelter's conflict status, Materion relies upon information provided by the RMI. RMI conducts a RMAP, in which it certifies smelters and refiners worldwide as being Conformant or Active (in the process of a RMAP assessment and previously Conformant) after confirming specific information, including country of origin for conflict minerals that the smelter/refiner may purchase for its operations. RMI makes available to the public the list of smelters/refiners that have been certified by RMI as Conformant or Active. Additionally, Materion is considering membership in RMI or other minerals authorities in order to obtain additional information such as country of origin and risk management assessment tools not available to non-members.

Step 3: Design and implement a strategy to respond to identified risks:

•Annually, Materion completes the RMAP Downstream Assessment, the RMI and OECD Due Diligence Guidance Expectations for Downstream companies, at the conclusion of its due diligence and provides a summary of the identified risks and gaps to senior management with recommended action plans to reduce risks and close gaps;

•Materion maintains a risk mitigation strategy with the goal of systematically reducing the extend of exposure to certain risk and the likelihood of its occurrence;

•Materion maintains a risk mitigation plan and monitors execution. New supplier onboarding includes requirements for all suppliers to provide a current CMRT and an agreement to respond to annual conflict

minerals surveys;

•Materion continues to systematically and procedurally limit purchasing with suppliers based on their unresponsiveness to conflict minerals inquiries or use of non-Conformant Smelters and Refiners;

•Materion places additional restrictions on smelter sources based on non-conflict mineral related customer requirements; and

•Additional fact finding, risk assessments and changes in circumstances take place as part of Materion's annual review of its Conflict Minerals Compliance Playbook.

Step 4: Carry out independent third-party audit of smelter/refiner's due diligence practices:

•In accordance with the OECD Guidelines, Materion participates and contributes through industry organizations to enhance transparency and traceability in the supply chain and supports independent third-party audits of smelters/refiners; and

•Materion is not in a position to audit smelter/refiners directly. Materion does, however, reach out to smelters identified by their suppliers to request that they participate in the RMI RMAP initiative and become certified as Conformant. In addition, Materion’s gold recycling operation in Buffalo, New York successfully completed the annual RMI RMAP to maintain its RMI Conformant Gold Refiner status, including having submitted relevant documentation, completed an on-site assessment and addressed relevant findings.

Step 5: Report annually on supply chain due diligence:

•Annually, Materion performs due diligence in their conflict minerals supply chain, maintains a process to summarize, review and approve compliance results, complete the Form SD and the Conflict Minerals Report and timely file the Form SD and any Conflict Minerals Report with the SEC.

Continuous Improvement of Supply Chain Due Diligence

The Company expects to continue to maintain its supply chain due diligence efforts including:

•Implement a strategy to support and build supplier capabilities and design improvement plans with suppliers to enhance the Company’s risk mitigation plan;

•Continue to assess the presence of conflict minerals in its supply chain as part of the its New Product Introduction ("NPI") process;

•Continue to require suppliers to identify the conflict minerals contained in the products they supply and when requested on an annual basis, to provide current, accurate and complete information on the smelters/refiners used in the manufacture of materials supplied to Materion;

•Continue to compare RCOI results to information collected via independent conflict free smelter validation programs such as the RMAP;

•Continue to partner with suppliers who are committed to participation in obtaining a "conformant" designation from an industry program such as the RMAP; and

•Continue to respond to customer requests to source responsibility and limit smelters active in the supply chain in CAHRAs, for minerals other than 3TG or due to non-conflict minerals sourcing concerns such as embargos or sanctioned countries.

Determination

Based on the process described above, Materion achieved a 100% response rate from the 58 direct material suppliers identified as supplying raw materials or parts containing conflict minerals and all but one smelter out of the 215 identified smelters or refiners were conformant.

Of the smelters identified in the RCOI due diligence process, the one reported non-conformant gold refiner was removed from the Responsible Minerals Initiative’s Conformant Gold Refiners List in August 2020 because the refiner was moved to the LBMA's former Good Delivery List at its request because the refiner no longer met the Good Delivery List requirements. The gold refiner is not expected to participate in the RMI RMAP process and Materion is now in the process of removing it from the supply chain, and as of May 24, 2021, successfully achieved removal of this refiner from all but one supplier. Additional non-conformant smelters were reported out of Indonesia but were identified as being closed in 2019 and were therefore removed from Materion’s list of smelters or refiners used in 2020.

Based on the information provided by Materion suppliers utilized during 2020, Materion believes that the facilities that may have been used to process conflict minerals in Materion’s products included the smelters and refiners lists in Appendix I. The suppliers’ responses include Conformant, Active and Known smelters, where Active smelters are in the process of recertification of their conformant status as well as the aforementioned single Known smelter that was previously Conformant.

Based on the due diligence efforts and the absence of full supply chain visibility throughout the supply base, Materion is unable to determine the origin of the conflict minerals and does not have sufficient information to conclusively determine the countries of origin of conflict minerals contained in Materion’s products.
