Exhibit 1.01

Conflict Minerals Report of Crown Holdings, Inc.

This Conflict Minerals Report (“CMR”) of Crown Holdings, Inc. (“Crown” or the “Company”) for calendar year 2020 was prepared in accordance with Rule 13p-1 under the Securities Exchange Act of 1934 and the Company’s Conflict Minerals Policy. Numerous terms in this CMR are defined in Rule 13p-1 or in the related Securities and Exchange Commission (“SEC”) Release No. 34-67716 (August 22, 2012) and the reader is referred to the same for such definitions. Throughout this report, the minerals tin, tantalum, tungsten and gold (collectively, “3TG”), when sourced in a way that directly or indirectly finances or benefits armed groups in Covered Countries, are referred to as “conflict minerals.”

Business Overview

Crown Holdings, Inc., through its subsidiaries, is a leading global supplier of rigid packaging products to consumer marketing companies, as well as transit and protective packaging products, equipment and services to a broad range of end markets. The Company has determined that tin is contained in the tinplate steel it purchases for its metal packaging businesses (the “Metal Packaging Business”). Additionally, the Company has determined that 3TG may be contained in certain purchased components for the products of both its can-making machinery and equipment business (the “Can Machinery Business”) and its transit packaging machinery and equipment businesses, as well as the tools (and spare parts) that it makes for transit packaging (collectively, the “Transit Machinery Businesses”).

Crown does not directly purchase any of the 3TG minerals. Crown’s supply chain is complex, and Crown is typically several tiers removed from the smelter or refiner and mineral origin. Because Crown has limited visibility beyond its direct suppliers to entities within the supply chain, Crown relies principally on its direct suppliers to provide information on the origin of the 3TG necessary to the functionality or production of Crown’s products.

Due Diligence Design Overview

Crown’s due diligence processes for tracing and sourcing 3TG in its products have been designed in conformance with the due diligence related steps of the framework in The Organisation 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 the related supplements for 3TG, consistent with the Company’s position as a downstream company. Crown also relied on information from the Responsible Minerals Assurance Process (“RMAP”), a voluntary initiative managed by the Responsible Minerals Initiative (the “RMI”) in which an independent third party audits the procurement activities of a smelter or refiner to determine with reasonable confidence that the minerals it processes originated from conflict-free sources. Upon completion of a successful audit, the smelter or refiner is designated by the RMI as “Conformant.” Where information from the RMI is not available, the Company conducts its own diligence, which includes: contacting its first-tier suppliers for additional information; conducting internet research; and analyzing the likelihood that the 3TG originated from a Covered Country based on the smelter’s location. In addition, Crown has engaged Assent Compliance (“Assent”), a third-party service provider, to assist with the contacting of and processing of responses received from suppliers to its Transit Machinery Businesses.

To guide its due diligence, the Company has established a due diligence compliance process that includes a documentation and record maintenance mechanism to ensure the retention of relevant documentation in a structured electronic database. Documentation with respect to the Company’s Transit Machinery Businesses is first separately

collected and stored using the Assent Compliance Platform before being integrated in the rest of the Company’s due diligence compliance process. The Company expects to continue to refine, revise and improve its due diligence compliance process as appropriate.

The Company’s due diligence on the source and chain of custody of the 3TG contained in the covered products included the following measures:

OECD Step 1 – Establish Strong Company Management Systems

Policy. Crown aims to avoid the use of conflict minerals in the manufacture of its products and is committed to complying with its reporting obligations under applicable law. Crown has adopted a company-wide Conflict Minerals Policy which is set forth on its website at https://www.crowncork.com/conflict-minerals-policy. In addition, Crown’s Supplier Code of Conduct includes a provision regarding responsible sourcing (Origin Mapping), and Crown’s written contracts with the tinplate steel suppliers to its Metal Packaging Business, and most of Crown’s written contracts with suppliers to its Can Machinery Business and Transit Machinery Businesses, contain obligations of the suppliers to cooperate with Crown in its efforts to eliminate conflict minerals from the supply chain. Suppliers who do not comply with Crown’s Conflict Minerals Policy may be denied future business, and those who violate contractual provisions or policies are subject to enforcement actions by Crown.

Personnel. The Company’s conflict minerals compliance effort involves a cross-functional group of personnel from the legal, finance and operations functions. This team is responsible for implementing Crown’s conflict minerals compliance strategy.

Supplier Engagement. The Company contacted all of the first-tier suppliers of tinplate steel for its Metal Packaging Business and contacted (or arranged for Assent to contact) almost all of the first-tier suppliers for its Can Machinery Business and Transit Machinery Businesses to provide them with notice of the relevant SEC requirements and to advise them of the Company’s commitment to responsibly source materials and of its due diligence expectations. The Company intends to archive the received supplier responses as part of its reasonable country of origin inquiry (“RCOI”) and due diligence. Feedback from this process will be used to modify, where appropriate, the design of the Company’s conflict minerals due diligence compliance process.

Grievance Mechanism. The Company’s existing procedures for reporting code of conduct or other ethics violations are also available for reporting conflict minerals compliance problems.

OECD Step 2 – Identify and Assess Risk in the Supply Chain

Identification of Risk. To identify risks in its supply chain, the Company first assessed the likelihood of the presence of conflict minerals in each of its products. If a product clearly does not contain 3TG (e.g., aluminum cans), the inquiry ended. For each of its other products, the Company used its own and outside resources to determine whether such product contains 3TG. At the end of this process, the Company determined that most of its steel containers and container components (e.g., cans, jar lids and bottle caps) contain tin. The Company also has determined that its Can Machinery Business’ products and its Transit Machinery Businesses’ products may contain 3TG.

The Company then contacted all of the first-tier suppliers of tinplate steel for its Metal Packaging Business and contacted (or arranged for Assent to contact) almost all of the first-tier suppliers for its Can Machinery Business and Transit Machinery Businesses identified through its RCOI to request information regarding the source and chain of custody of 3TG in its supply chain. To facilitate the collection of complete, accurate, standardized and verifiable

information, the Company relied primarily on the Conflict Minerals Reporting Template (the “CMRT”) made available by the RMI. The CMRT facilitates the transfer of information through the supply chain regarding country of origin, mine location and smelters and refiners used. Written instructions and recorded training illustrating the use of the CMRT are available on the RMI’s website.

Assessment of Risk. Upon receipt of completed CMRTs from its suppliers, the Company assessed the due diligence efforts of any identified smelter or refiner by examining the information provided in the CMRT to determine if the smelter or refiner has been validated under the RMI’s RMAP as “Conformant.” The RMAP provides information regarding those smelters or refiners that, following an independent third-party audit, have been found to be compliant with the RMAP’s assessment protocols to assure sourcing of only conflict-free materials. Where information from the RMI is not available, or where the supplier provides information in a form other than the CMRT, the Company conducts its own diligence, which includes: contacting its first-tier suppliers for additional information; conducting internet research; and analyzing the likelihood that the 3TG originated from a Covered Country based on the smelter’s location. In addition, the Company has engaged Assent to conduct CMRT validation checks as part of the due diligence of its Transit Machinery Businesses. Assent evaluates supplier responses for plausibility, consistency, and gaps, and conducts additional supplier inquiries to address issues such as incomplete data on CMRTs, responses that did not identify smelters or refiners for listed metals, and responses that identified organizations as smelters or refiners which were not verified as such through further analysis and research.

OECD Step 3 – Design and Implement a Strategy to Respond to Identified Risks

The Company expects to take the following steps, among others, to improve its due diligence measures, increase supply chain transparency and further mitigate the risk that the 3TG contained in its products may finance or benefit armed groups in the Covered Countries:

• continue to engage and document communication with suppliers to increase the response rate and facilitate the collection of current, accurate and complete information about the supply chain, smelters, refiners and mineral origin;

• encourage suppliers to implement responsible sourcing and request that suppliers encourage smelters and each of their refiners to obtain a “conflict-free” designation from an independent third-party auditor;

• enforce its rights under its Supplier Code of Conduct regarding responsible sourcing; and

• report findings from Crown’s conflict minerals due diligence compliance process to senior management.

OECD Step 4 – Carry Out an Independent Third-Party Audit of Supply Chain Due Diligence

The Company does not have any direct relationships with smelters or refiners that process 3TG, and it does not perform or direct audits of these entities within its supply chain. As an alternative, the Company intends to rely on information collected and provided by independent third-party audit programs, such as the RMAP, when necessary.

Due Diligence Results

Facilities and Country of Origin of 3TG

Metal Packaging Business

Crown purchases tinplate steel from fifty-five (55) suppliers of primary cansheet for its Metal Packaging Business, fifty-two (52) of whom have provided Crown with a list of their tin smelters in connection with Crown’s due diligence compliance process. The three (3) suppliers that did not provide a list of tin smelters all certified that none of the 3TG found in their products was sourced from a Covered Country.

Tinplate steel from any of these fifty-five (55) suppliers may be used in Crown’s metal packaging products. Tin is the only 3TG mineral identified in the Company’s Metal Packaging Business. The Company contacted all of these suppliers as part of its due diligence compliance process. Of the suppliers who provided complete responses to the Company’s inquiry, three (3) of these suppliers indicated the intentional addition or use of 3TG in their products or production process which was sourced from a Covered Country, but the minerals came from a smelter or refiner that has been validated under the RMI’s RMAP as “Conformant.” The countries in which the smelters identified by the Company’s tinplate steel suppliers are located are as follows: Belgium, Bolivia, Brazil, China, Indonesia, Republic of Korea (South Korea), Malaysia, Peru, Spain and Thailand.

Can Machinery Business

None of Crown’s direct suppliers are 3TG smelters and Crown does not purchase any 3TG directly for its Can Machinery Business’ products. Any 3TG materials that may be part of Crown’s Can Machinery Business’ products are incorporated into components (or components of components) or raw materials that are purchased by Crown and included in the Can Machinery Business’ products.

As a result of Crown’s RCOI process and due diligence for its Can Machinery Business’ products, which account for less than 2% of Crown’s net sales in fiscal year 2020, Crown identified as in-scope and contacted a total of one hundred twenty-six (126) suppliers. All suppliers contacted, representing, collectively, over 95% of the Can Machinery Business’ annual purchases of raw materials and components, responded to Crown’s inquiry. Of the suppliers who provided completed CMRTs, twenty-three (23) suppliers indicated the intentional addition or use of 3TG in their products or production process. Four (4) of those twenty-three (23) suppliers indicated that one or more of the smelters that provided the 3TG found in the parts, sub-assemblies or components sold to them did source from a Covered Country (and had not been validated under the RMI’s RMAP as “Conformant”). None of these four (4) suppliers, who each sell a wide range of general supply products such as hardware, controllers and other components, had the capability to identify the country of origin of the 3TG found in the products that they specifically sold to Crown because of the nature of the products sold to Crown. Twelve (12) of the twenty-three (23) suppliers indicated that none of the smelters that provided the 3TG found in the products sold to Crown sourced from a Covered Country. Every one of the smelters identified by these twelve (12) suppliers has been identified by the RMI as “Conformant” or was cleared by the Company’s own due diligence investigation. The remaining seven (7) of the twenty-three (23) suppliers either (i) indicated that the 3TG found in the products sold to Crown was not sourced from a Covered Country but did not provide a smelter list to verify the declaration or (ii) indicated that they were unable to confirm that one or more of the smelters that provided the 3TG found in the products sold to Crown did not source from a Covered Country because of the nature of the products sold to Crown. The information provided by the responding suppliers was often incomplete or unverifiable. Additionally, based on the information provided by many of Crown’s suppliers who are engaged in general supply industries such as hardware, controllers and other components, it cannot be verified that all the smelters identified contributed to parts that ended up in Crown products or even that the 3TG materials were incorporated in Crown products, since some of these responses cover the entire product range of the supplier’s products and not just those sold to Crown.

Because of the long supply chain from most smelters to the component suppliers to Crown’s Can Machinery Business, information provided to Crown by its component suppliers did not enable Crown to verify the country of origin for all of the 3TG added to the specific parts that ended up in Crown’s can-making machinery and equipment products.

Transit Machinery Businesses

The Company acquired its Transit Packaging Division, including the Transit Machinery Businesses, on April 3, 2018. As was done last year, which was the first declaration year for the newly acquired businesses, the Company this year assessed the likelihood of the presence of conflict minerals in each of the products of its Transit Packaging Division as part of Step 2 of its due diligence compliance process described above. At the end of this process, the Company determined that its transit packaging metal strapping business and plastic and paperboard businesses do not use or manufacture products that contain 3TG. Certain products of its Transit Machinery Businesses, however, may contain 3TG.

As a result of Crown’s RCOI process and due diligence for its Transit Machinery Businesses products, Crown identified as in-scope a total of four hundred twenty-nine (429) suppliers and delivered this list of in-scope suppliers to Assent. Assent then attempted to verify, for each of the in-scope suppliers, whether that supplier is active and self-certifies that its products do not contain 3TG. Assent contacted and solicited the completion of CMRTs (much like Crown does for its Can Machinery Business) from each of the in-scope suppliers that is active and not certified.

For calendar year 2020, three hundred sixty-seven (367) suppliers of Crown’s Transit Machinery Businesses, representing more than 85% of the number of suppliers to Crown’s Transit Machinery Businesses contacted and, collectively, over 95% of the Transit Machinery Businesses’ annual purchase value of raw materials and components, responded to Assent’s inquiry. Of the suppliers who provided completed CMRTs, one hundred four (104) suppliers indicated the intentional addition or use of 3TG in their products or production process. Fifty-one (51) of those one hundred four (104) suppliers indicated that none of the smelters that provided the 3TG found in the products sold to Crown sourced from a Covered Country. Fourteen (14) of those one hundred four (104) suppliers were unable to confirm which smelters provided the 3TG found in the products specifically sold to the Transit Machinery Businesses. Thirty-nine (39) of those one hundred four (104) suppliers indicated that one or more of the smelters that provided the 3TG to them did source from a Covered Country. None of these thirty-nine (39) suppliers, who all sell a wide range of general supply products such as hardware, controllers and other components, had the capability to identify the country of origin of the 3TG found in the products specifically sold to the Transit Machinery Businesses because of the nature of the products sold to the Company. The information provided by the responding suppliers is, by nature, unverifiable. Additionally, as it relates to Crown’s suppliers who are engaged in general supply industries such as hardware, controllers and other components, it cannot be verified that all the smelters identified contributed to parts that ended up in Crown products, or even that the 3TG materials were incorporated in Crown products, since some of these responses cover the entire product range of the supplier’s products and not just those sold to Crown.

Due Diligence Improvements

Crown will undertake the following steps during the next compliance period:

• pursue the sustainability goals announced as part of its Twentyby30 program to reduce the amount of minerals mined from the Earth;

• continue to direct suppliers to the RMI for information and encourage them to support the RMI’s efforts through membership;

• continue to refine its due diligence process for suppliers who indicate the intentional addition or use of 3TG in their products or production process but who (i) are unable to confirm whether the smelters that provided the 3TG found in the products sold to Crown businesses source from a Covered Country or (ii) did not provide a smelter list so that their responses could be verified; and

• further engage with suppliers that did not respond to the request for information for calendar year 2020.
