Conflict Minerals Report of AmerisourceBergen Corporation

For the Reporting Period from January 1, 2021 to December 31, 2021

1. Introduction

This Conflict Minerals Report of AmerisourceBergen Corporation ("AmerisourceBergen" or the "Company") for the reporting period from January 1, 2021 to December 31, 2021 is presented in accordance with Rule 13p-1 ("Rule 13p-1") under the Securities Exchange Act of 1934, as amended. Rule 13p-1 imposes certain reporting obligations on Securities and Exchange Commission (the "SEC") registrants who manufacture or contract for the manufacture of products containing “conflict minerals” that are necessary to the functionality or production of their products. “Conflict minerals” are currently defined by the SEC as columbite-tantalite (coltan), cassiterite, gold, wolframite, or their derivatives, which are limited to tantalum, tin, and tungsten (collectively, "3TG Minerals").

Registrants that manufacture, or contract to manufacture, products that contain, or components that use, 3TG Minerals must conduct in good faith a reasonable country of origin inquiry ("RCOI") designed to determine whether any of the 3TG Minerals originated in the Democratic Republic of the Congo or an adjacent country (collectively, the "Covered Countries") or are from recycled or scrap sources. If, based on such inquiry, the registrant knows or has reason to believe that any of the 3TG Minerals contained in its products originated or may have originated in a Covered Country and knows or has reason to believe that such 3TG Minerals may not be from recycled or scrap sources, the registrant must conduct due diligence on the sources and chain of custody to conclude if the 3TG Minerals contained in those products did or did not directly or indirectly finance or benefit armed groups in the Covered Countries.

2. Company Overview

AmerisourceBergen is one of the largest global pharmaceutical sourcing and distribution services companies, helping both healthcare providers and pharmaceutical and biotech manufacturers improve patient access to products and enhance patient care. AmerisourceBergen delivers innovative programs and services designed to increase the effectiveness and efficiency of the pharmaceutical supply chain in both human and animal health. More specifically, AmerisourceBergen distributes a comprehensive offering of brand-name, specialty brand-name, and generic pharmaceuticals, over-the-counter healthcare products, home healthcare supplies and equipment, and related services to a wide variety of healthcare providers located in the United States and select global markets, including acute care hospitals and health systems, independent and chain retail pharmacies, mail order pharmacies, medical clinics, long-term care and alternate site pharmacies, physician practices, medical and dialysis clinics, veterinarians, and other customers. Additionally, AmerisourceBergen furnishes healthcare providers and pharmaceutical manufacturers with an assortment of related services, including data analytics, outcomes research, reimbursement and pharmaceutical consulting services, niche premium logistics services, inventory management, pharmacy automation, pharmacy management, and packaging solutions.

3. Product Description

AmerisourceBergen identified five types of products that it manufactures or contracts to have manufactured that contain necessary 3TG Minerals (such products are referred to herein as "Covered Products"). Accordingly, AmerisourceBergen conducted in good faith a RCOI to determine whether any of the 3TG Minerals in the Covered Products originated in the Covered Countries.

A business in the Company’s U.S. Healthcare Solutions reportable segment provides technology solutions for physician practices in the form of automated cabinets that are designed to assist in inventory management and refrigerated medication storage. These cabinets contain 3TG Minerals. The Company's MWI Animal Health business has a weight-based flow control and monitoring device for animal feed, a liquid application system for animal feed, surgical instruments, and surgical implants that also contain 3TG Minerals.

AmerisourceBergen does not directly purchase any 3TG Minerals from any source. AmerisourceBergen is a downstream company in the supply chain, and there are many third parties in the supply chain between the ultimate manufacturer of each Covered Product and the original sources of 3TG Minerals. AmerisourceBergen must therefore rely on its suppliers to provide information regarding the origin of the 3TG Minerals in the Covered Products.

4. Reasonable Country of Origin Inquiry

For Covered Products, AmerisourceBergen completed a RCOI utilizing the Responsible Minerals Initiative's Conflict Minerals Reporting Template ("CMRT") for data collection. To conduct the RCOI, direct suppliers were engaged to collect information regarding the presence and sourcing of 3TG Minerals used in the Covered Products. Information was collected and stored using an online platform provided by a third-party supply-chain consultant. AmerisourceBergen, with the assistance of the consultant, reviewed the information to determine whether any 3TG Minerals originated in the Covered Countries or were from recycled or scrap sources.

Supplier Engagement

AmerisourceBergen conducted the following steps to obtain information from suppliers:

•The Company sent an introduction email to direct suppliers determined to be in-scope, describing the Company's conflict minerals compliance program requirements and the Covered Products containing raw materials acquired from the supplier, and identifying the Company's third-party supply chain consultant as a partner in the program.

•Following the introductory email, the consultant sent a subsequent email to suppliers containing a registration and survey request link for an on-line data collection platform.

•In an effort to increase awareness of the conflict minerals compliance program, the initial registration email identified a conflict minerals supplier resource center, which was established and is maintained by the Company's third-party supply chain consultant. The supplier resource center contains, among other things, frequently asked questions concerning 3TG Minerals tracing and serves as an educational tool to enable the Company's suppliers to develop a deeper understanding of the program and why information was being requested. There were also opportunities for suppliers to participate in webinars providing information on the SEC’s rules related to conflict minerals.

•Following the initial introduction to the program and the information request, the consultant sent up to three reminder emails to each non-responsive supplier requesting survey completion.

Information Requested

Suppliers were asked to provide information regarding the sourcing of 3TG Minerals included in supplies they sold to AmerisourceBergen with the ultimate goal of identifying the smelters or refiners and

associated mine countries of origin. Suppliers that had already performed a RCOI through the use of the CMRT were asked to upload this document into the consultant’s system or to provide this information in the online survey version.

Quality Assurance

Supplier responses were evaluated by the third-party supply-chain consultant for plausibility, consistency, and gaps. The consultant also conducted additional outreach with specific suppliers as needed to address issues, including incomplete data on CMRT reporting templates, responses that did not identify smelters or refiners for listed minerals, and smelters or refiners with information that could not be verified.

Reasonable Country of Origin Inquiry Results

A total of 22 suppliers were identified by AmerisourceBergen as in-scope for conflict mineral regulatory purposes and contacted as part of the RCOI process. Twelve of the in-scope suppliers (55%) responded with a CMRT. Of the 12 suppliers that responded with a CMRT, eight (67%) confirmed that one or more of the 3TG Minerals are necessary to the functionality or production of the products that they supply to AmerisourceBergen.

Suppliers indicating use of 3TG Minerals identified a total of 341 smelters and refiners that may have been used to supply the 3TG Minerals contained in the products sold to AmerisourceBergen for its Covered Products. Based on the Company's third-party supply-chain consultant’s smelter and refiner database, 53 of the 341 smelters or refiners may source 3TG Minerals from the Covered Countries. Out of the 53 smelters and refiners with indicia of sourcing from Covered Countries, 48 are certified as conflict free pursuant to the Responsible Minerals Initiative's Responsible Minerals Assurance Process and/or the London Bullion Market Good Delivery Program. For five of the 53 smelters and refiners with indicia of sourcing from the Covered Countries, there is no corresponding conflict free certification. To the extent that a smelter or refiner identified by a supplier was not certified as conflict-free by an independent third-party, the Company’s third-party supply-chain consultant attempted to contact that smelter or refiner to gain information about its sourcing practices.

The suppliers reported the smelter and refiner information at a company level and not at a product level. Therefore, based on the information reported by the suppliers, AmerisourceBergen was unable to determine whether any of the identified smelters or refiners were in its supply chain. In addition, due to the lack of detail provided by the suppliers, AmerisourceBergen was unable to confirm that the 3TG Minerals in its products were processed by any particular smelter or smelters and is, therefore, unable to identify the processing facilities, country of origin, mine or location of origin of such 3TG Minerals.

5. Design of and Implementation of Due Diligence

AmerisourceBergen's due diligence process is based on the Organization for Economic Cooperation and Development's (“OECD”) Due Diligence Guidance for Responsible Supply Chains of Minerals from Conflict-Affected and High-Risk Areas: Third Edition (2016). It is important to note that the OECD Guidance was written for both upstream and downstream companies in the supply chain. As AmerisourceBergen is a downstream company in its supply chain, its due diligence practices were tailored accordingly.

Due diligence measures undertaken by AmerisourceBergen that are consistent with the OECD Guidance include the following:

•Adopted a conflict minerals policy. AmerisourceBergen's conflict minerals policy is publicly available at investor.amerisourcebergen.com.

•Included requirements in AmerisourceBergen’s Supplier Code of Conduct for suppliers to support the Company’s commitment to reduce and, where possible, eliminate from its supply chain the use of conflict minerals, and to take reasonable steps to track the source of minerals used in their products.

•Used an internal team to conduct supply chain due diligence.

•Used a third-party consultant to assist with due diligence of its supply chain.

•Attempted to identify the smelters or refiners in its supply chain.

•To the extent that a smelter or refiner identified by a supplier was not certified as conflict-free by an independent third-party, attempted to contact that smelter or refiner to gain information about its sourcing practices.

•Reported risk management findings to senior management.

•Reports annually on supply chain due diligence.

The Specialized Disclosure Report on Form SD and this Conflict Minerals Report are publicly available on the Company’s website at investor.amerisourcebergen.com.

6. Steps to Improve Due Diligence and Risk Mitigation

For future reporting periods, AmerisourceBergen intends to improve upon its supply chain due diligence efforts and its efforts to reduce the risk of 3TG Minerals benefiting armed groups in the Covered Countries via the following measures:

•Continue to assess the presence of 3TG Minerals in its supply chain.

•Clearly communicate expectations with regard to supplier performance, transparency and sourcing, including informing suppliers of the AmerisourceBergen Conflict Minerals Policy.

•Continue to engage with suppliers to improve the accuracy and completeness of the information provided to AmerisourceBergen about AmerisourceBergen’s supply chain.

•Continue to compare the RCOI results to information collected via independent conflict free smelter validation programs, such as the Conflict Free Sourcing Initiative's Conflict-Free Smelter Program.

•Review the work performed by the third-party supply chain consultant to evaluate its contributions to AmerisourceBergen's conflict minerals compliance program.
